AB  - A specific feature of dyslipidemia in pregnancy is increased high-density lipoprotein (HDL) cholesterol concentration, which is probably associated with maternal endothelium protection. However, preeclampsia is most often associated with low HDL cholesterol, and the mechanisms behind this change are scarcely explored. We aimed to investigate changes in HDL metabolism in risky pregnancies and those complicated by late-onset preeclampsia. We analyze cholesterol synthesis (cholesterol precursors: desmosterol, 7-dehydrocholesterol, and lathosterol) and absorption markers (phytosterols: campesterol and β-sitosterol) within HDL particles (NCSHDL), the activities of principal modulators of HDL cholesterol’s content, and major HDL functional proteins levels in mid and late pregnancy. On the basis of the pregnancy outcome, participants were classified into the risk group (RG) (70 women) and the preeclampsia group (PG) (20 women). HDL cholesterol was lower in PG in the second trimester compared to RG (p < 0.05) and followed by lower levels of cholesterol absorption markers (p < 0.001 for campesterolHDL and p < 0.05 for β-sitosterolHDL). Lowering of HDL cholesterol between trimesters in RG (p < 0.05) was accompanied by a decrease in HDL phytosterol content (p < 0.001), apolipoprotein A-I (apoA-I) concentration (p < 0.05), and paraoxonase 1 (PON1) (p < 0.001), lecithin–cholesterol acyltransferase (LCAT) (p < 0.05), and cholesterol ester transfer protein (CETP) activities (p < 0.05). These longitudinal changes were absent in PG. Development of late-onset preeclampsia is preceded by the appearance of lower HDL cholesterol and NCSHDL in the second trimester. We propose that reduced capacity for intestinal HDL synthesis, decreased LCAT activity, and impaired capacity for HDL-mediated cholesterol efflux could be the contributing mechanisms resulting in lower HDL cholesterol.

AB  - Background A three-year COVID-19 pandemic revealed a spectrum of disease severity and clinical manifestations. The most intriguing part of this phenomenon lays in interindividual variability in COVID-19 course among patients, which is attributable to patient's age, comorbidities and general health status. Focus of this follow-up study was to assess leukocyte telomere length change in mild-to-moderate COVID-19 patients and concomitant influence of inflammation, oxidative stress (OS), pulmonary involvement and implemented therapy on the course of the disease.

Material and methods Routine biochemical/haematological parameters, markers of OS (prooxidants and antioxidants), vitamin D, IgM and IgG antibodies level and relative length of leukocyte telomeres (rLTL) were measured at three time-points (at diagnosis, after 14 and 21 days from the disease onset) in blood samples of 31 consecutive COVID-19 patients, with a mild (n=16) and moderate (n=15) form of the disease, treated on an outpatient basis.

Results Although the patients had reduced rLTL at baseline (median: 0.592; 25th – 75th percentiles: 0.518-0.724), it significantly increased during the follow-up (median: 0.773; 25th – 75th percentiles: 0.615-0.923; P<0.01). The rate of telomere attrition was associated with the extent of OS and pulmonary involvement. During follow-up, the burden of OS was reduced, while antioxidative defence mechanisms were recovered. The use of antibiotics and N-acetylcysteine-propolis supplementation was associated with telomere lengthening.

Conclusion Results of this study revealed significant interaction between OS, inflammation and leukocyte telomere length attrition in COVID-19. Our data suggest that rRTL can be a biomarker that enables more precise therapy decision and accurate patient status estimation.

AB  - The aim of this multicentric study was to assess the impacts of oxidative stress, inflam-
mation, and the presence of small, dense, low-density lipoproteins (sdLDL) on the antioxidative
function of high-density lipoprotein (HDL) subclasses and the distribution of paraoxonase-1 (PON1)
activity within HDL in patients with ST-segment elevation acute myocardial infarction (STEMI). In
69 STEMI patients and 67 healthy control subjects, the lipoproteins’ subclasses were separated using
polyacrylamide gradient (3–31%) gel electrophoresis. The relative proportion of sdLDL and each
HDL subclass was evaluated by measuring the areas under the peaks of densitometric scans. The
distribution of the relative proportion of PON1 activity within the HDL subclasses (pPON1 within
HDL) was estimated using the zymogram method. The STEMI patients had significantly lower
proportions of HDL2a and HDL3a subclasses (p = 0.001 and p < 0.001, respectively) and lower pPON1
within HDL3b (p = 0.006), as well as higher proportions of HDL3b and HDL3c subclasses (p = 0.013
and p < 0.001, respectively) and higher pPON1 within HDL2 than the controls. Independent positive
associations between sdLDL and pPON1 within HDL3a and between malondialdehyde (MDA) and
pPON1 within HDL2b were shown in the STEMI group. The increased oxidative stress and increased
proportion of sdLDL in STEMI are closely related to the compromised antioxidative function of small
HDL3 particles and the altered pPON1 within HDL.

AB  - Purpose: End-stage renal disease patients on chronic hemodialysis (HD) have a shortened life expectancy compared to the general population. The aim of this study was to evaluate a possible link between three new and emerging factors in renal pathophysiology: Klotho protein, telomere length in peripheral blood mononuclear cells (TL) and redox status parameters before HD (bHD) and after HD (aHD), and to test mortality prediction capability of these emerging parameters in a population of HD patients. Methods: The study included 130 adult patients with average age 66 (54–72), on HD (3 times per week; 4–5 h per session). Klotho level, TL, routine laboratory parameters, dialysis adequacy and redox status parameters: advanced oxidation protein products (AOPP), prooxidant–antioxidant balance (PAB), superoxide anion (O2.−), malondialdehyde (MDA), ischemia-modified albumin (IMA), total sulfhydryl group content (SHG), and superoxide dismutase (SOD) were determined. Results: Klotho concentration was significantly higher aHD; 68.2 (22.6–152.9) vs. bHD 64.2 (25.5–119.8) (p = 0.027). The observed increase in TL was not statistically significant. AOPP, PAB, SHG, and SOD activity were significantly increased aHD (p > 0.001). The patients with the highest mortality risk score (MRS) had significantly higher PAB bHD (p = 0.002). Significantly lower O2.− (p < 0.001), SHG content (p = 0.072), and IMA (p = 0.002) aHD were found in patients with the lowest MRS values. Principal component analysis revealed redox balance-Klotho factor as a significant predictor of high mortality risk (p = 0.014). Conclusion: Decreased Klotho and TL attrition as well as redox status disturbance could be connected with higher mortality rate in HD patients.

Results: Klotho concentration was significantly higher aHD; 68.2 (22.6–152.9) vs. bHD 64.2 (25.5–119.8) (p = 0.027). The observed increase in TL was not statistically significant. AOPP, PAB, SHG, and SOD activity were significantly increased aHD (p > 0.001). The patients with the highest mortality risk score (MRS) had significantly higher PAB bHD (p = 0.002). Significantly lower O2.− (p < 0.001), SHG content (p = 0.072), and IMA (p = 0.002) aHD were found in patients with the lowest MRS values. Principal component analysis revealed redox balance-Klotho factor as a significant predictor of high mortality risk (p = 0.014). Conclusion: Decreased Klotho and TL attrition as well as redox status disturbance could be connected with higher mortality rate in HD patients.",

AB  - Background/Aim. One of the complications that can oc-
cur during pregnancy is the development of preeclampsia
(PE). The main characteristics of this condition are high
blood pressure and very often signs of kidney damage or
other organ damage. The condition affects 5–7% of all
pregnant women and is one of the main factors of maternal
and perinatal morbidity and mortality worldwide. The aim
of this study was to investigate the structural and functional
modifications of high-density lipoprotein (HDL) particles
during high-risk pregnancies (HRP) for PE development.
Methods. The longitudinal prospective study included a to-
tal of 91 pregnant women with a HRP for developing PE.
Out of this total number, 71 women did not develop PE
until delivery, and this group was designated as the group
without PE (WPE). The rest of the 20 HRP women devel-
oped PE before delivery and were designated as the PE
group. The blood was sampled toward the end of each tri-
mester and before the delivery. The distribution of HDL
particles was determined by the vertical 3–31% polyacryla-
mide gradient gel electrophoresis method. The antioxidative capacity of HDL particles was measured by the activity of
the HDL-associated enzyme – paraoxonase 1 (PON1).
PON1 activity was determined by the method of kinetic
spectrophotometry from serum samples. Results. The re-
sults have shown that the proportions of HDL 2b particles
significantly increased in the 2nd trimester (p ˂ 0.05) and
remained increased until the end of pregnancy in the WPE
group. PON1 activity was significantly higher in the 3 rd tri-
mester (p < 0.05) of the WPE group. In the PE group, we
found that the proportions of HDL 3a particles significantly
decreased in the 2 nd trimester (p < 0.05) and remained de-
creased until the end of pregnancy. PON1 activity has not
changed in the PE group during pregnancy. Conclusion.
Dyslipidemia in pregnancy could be associated with differ-
ent modifications of HDL particles. The adaptive pregnancy
mechanisms expressed as a functional modification of HDL
particles in pregnant women who develop PE seem inade-
quate and, therefore, lose their atheroprotective role.

AB  - Oxidative stress is the consequence of an overproduction of reactive oxygen species (ROS) that exceeds the antioxidant defense mechanisms. Increased levels of ROS contribute to the development of cardiovascular disorders through oxidative damage to macromolecules, particularly by oxidation of plasma lipoproteins. One of the most prominent features of atherogenic dyslipidemia is plasma accumulation of small dense LDL (sdLDL) particles, characterized by an increased susceptibility to oxidation. Indeed, a considerable and diverse body of evidence from animal models and epidemiological studies was generated supporting oxidative modification of sdLDL particles as the earliest event in atherogenesis. Lipid peroxidation of LDL particles results in the formation of various bioactive species that contribute to the atherosclerotic process through different pathophysiological mechanisms, including foam cell formation, direct detrimental effects, and receptor-mediated activation of pro-inflammatory signaling pathways. In this paper, we will discuss recent data on the pathophysiological role of oxidative stress and atherogenic dyslipidemia and their interplay in the development of atherosclerosis. In addition, a special focus will be placed on the clinical applicability of novel, promising biomarkers of these processes.

AB  - Disorders of lipoprotein metabolism and glucose homeostasis are common consequences of insulin resistance and usually co-segregate in patients with metabolic syndrome and type 2 diabetes mellitus (DM). Insulin-resistant subjects are characterized by atherogenic dyslipidemia, a specific lipid pattern which includes hypertriglyceridemia, reduced high-density lipoprotein cholesterol level, and increased proportion of small, dense low-density lipoprotein (LDL). Chronic hyperglycemia favors the processes of non-enzymatic glycation, leading to the increased production of advanced glycation end products (AGEs). Apart from direct harmful effects, AGEs are also potent inducers of oxidative stress and inflammation. In addition, increased AGEs’ production may induce further qualitative modifications of small, dense LDL particles, converting them to glycated LDLs. These particles are even more atherogenic and may confer an increased cardiovascular risk. In this narrative review, we summarize the available evidence of the pathophysiological role and clinical importance of circulating AGEs and glycated LDLs in patients with dyslipidemia, particularly those with DM and related complications. In addition, we discuss recent advances and the issues that should be improved regarding laboratory assessment of AGEs and glycated LDLs, as well as the possibilities for their therapeutic modulation.

AB  - In order to understand the metabolic and immune potential of adiponectin in
colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC.
AB  - Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema

abstract = "In order to understand the metabolic and immune potential of adiponectin in
colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC., Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema
grupama: 38 uzoraka zdravih subjekata i 55 pacijenata sa CRC. GSEA analiza skupa podataka
GSE44076 je implicira da su nivoi iRNK ADIPOR1 negativno korelirali sa MTORC1 i TNF-α
NF-κB signalnim putevima u tumorskom tkivu. Istovremeno, ADIPOR2 je bio pozitivno

AB  - The pathogenesis of the COVID-19 infection caused by the SARS-CoV-2 coronavirus is
the subject of active research worldwide. As a complex disease, it is suspected that oxidative
stress plays a role in its pathogenesis and contributes to the progressive shortening of
telomeres. Patients aged 25–84 years (n=31) were monitored at the time of diagnosis, as
well as at control on the 14th and 21st days. Redox status parameters were determined: total
oxidant status (TOS), superoxide anion radical (O2.-), prooxidant-antioxidant balance (PAB),
advanced protein oxidation products (AOPP), malondialdehyde (MDA), and ischemia-
modified albumin (IMA) as prooxidants and total antioxidant status (TAS), superoxide-
dismutase (SOD) and paraoxonase 1 (PON1) enzyme activity, total antioxidant and total
oxidant status ratio (TAS/TOS), and total sulfhydryl groups (SHG) as antioxidants. Patients
have the shortest telomeres at diagnosis and their length increases during recovery. A
statistically significant difference in rTL was shown in patients at the time of diagnosis and
after 21 days (p=0.008). rTL has a statistically significant negative correlation with SHG in
patients at the time of diagnosis (ρ=-0.386, p=0.038), as well as in patients after 14 days (ρ =-
0.389, p=0.037). After 21 days, a statistically significant positive correlation was shown
between rTL and SOD (ρ =0.381, p=0.046). The obtained results indicate progressive
shortening of telomeres caused by COVID-19 infection, impaired redox status, as well as the
change of these parameters during recovery, which confirms the link between oxidative
stress and rTL, as well as the participation of these processes in the pathogenesis of COVID-
19.
AB  - Patogeneza COVID-19 infekcije izazvane koronavirusom SARS-CoV-2 je predmet
aktivnog istraživanja širom sveta. Kako je u pitanju složena bolest, smatra se da i u njenoj
patogenezi leži oksidativni stres, koji doprinosi progesivnom skraćivanju telomera. Pacijenti
starosti 25-84 godina (n=31) praćeni su u trenutku postavljanja dijagnoze, kao i na kontroli
14. i 21. dana. Parametri redoks statusa određivani su iz seruma ili plazme odgovarajućim
spektrofotometrijskim metodama, dok je iz leukocita periferne krvi merena relativna dužina
telomera (rTL) pomoću qPCR metode. Od parametara oksidativnog statusa određivani su:
totalni oksidantni status (TOS), superoksidni anjon radikal (O2.- ), prooksidantno-
antioksidantni balans (PAB), uznapredovali produkti oksidacije proteina (AOPP),
malondialdehid (MDA), ishemijom modifikovan albumin (IMA). Kao parametri
antioksidativne zaštite određivani su: totalni antioksidantni status (TAS), aktivnost enzima
superoksid-dismutaze (SOD) i paraoksonaze 1 (PON1), odnos totalnog antioksidantnog i
totalnog oksidantnog statusa (TAS/TOS), kao i ukupne sulfhidrilne grupe (SHG). Pacijenti u
trenutku postavljanja dijagnoze imaju najkraće telomere i njihova dužina se povećava tokom
oporavka. Pokazana je statistički značajna razlika u rTL kod pacijenata u trenutku
postavljanja dijagnoze i nakon 21 dan (p=0,008). rTL je u statistički značajnoj negativnoj
korelaciji sa SHG kod pacijenata u trenutku postavljanja dijagnoze (ρ=-0,386, p=0,038), kao i
kod pacijenata nakon 14 dana oporavka (ρ=-0,389, p=0,037). Nakon 21 dan, pokazana je
statistički značajna pozitivna korelacija između rTL i SOD (ρ=0,381, p=0,046). Dobijeni
rezultati ukazuju na progresivno skraćenje telomera izazvano COVID-19 infekcijom, narušen
redoks status, kao i na promenu ovih parametara tokom oporavka, koja potvrđuje vezu
između oksidativnog stresa i rTL, kao i učešće ovih procesa u patogenezi COVID-19.

AB  - Background. Metabolic alterations, particularly disorders of lipoprotein metabolism in COVID-19, may affect the course and outcome of the disease. This study aims at evaluating the lipoprotein profile and redox status in SARS-CoV-2 infected patients with different pneumonia severity and their association with lethal outcomes. Methods. The prospective cohort study was performed on 98 COVID-19 patients with mild, moderate, and severe pneumonia. Lipid and inflammatory parameters, lipoprotein subclasses, and redox status biomarkers were determined at the study entry and after one week. Results. Compared to patients with mild and moderate pneumonia, severely ill patients had higher oxidised low-density lipoprotein (oxLDL) and malondialdehyde levels and lower high-density lipoprotein cholesterol (HDL-C) concentrations and paraoxonase 1 activity. Reduction in the proportion of large HDL 2a subclasses with a concomitant increase in the proportion of smallest HDL 3c and small dense LDL (sdLDL) particles was observed in patients with severe disease during the time. However, these changes were reversed in the mild and moderate groups. The results showed a positive association between changes in oxLDL and total antioxidative status. However, prooxidants and antioxidants in plasma were lower in patients with lethal outcomes. Conclusions. Increased levels of oxLDL and sdLDL particles may contribute to the severity of COVID-19. The role of oxidative stress should be clarified in further studies, mainly its association with lethal outcomes.

AB  - Adiponectin (ADIPOQ) as both a regulator of metabolic homeostasis and a protein involved in immune response might be of particular interest to contemporary laboratory medicine, especially in terms of minimally invasive diagnostics. The diverse roles of ADIPOQ with regard to the immune and metabolic aspects of colorectal carcinogenesis have been proposed. However, the expression of its receptors ADIPOR1 and ADIPOR2 is scarcely explored in peripheral blood mononuclear cells (PBMCs). Moreover, ADIPORs’ relationships with the immune response mediator TNF-α have not been previously investigated in the PBMCs of CRC patients. This study used both in silico and observational case–control analyses with the aim of exploring the association of ADIPOR gene expression and ADIPOQ single nucleotide polymorphisms (SNPs) with the inflammatory marker TNF-α and lipid status parameters in patients with CRC. Publicly available transcriptomic datasets (GSE47756, GSE44076) obtained from analyses of monocytes and CRC tissue samples were employed for the in silico evaluation of ADIPORs’ specific genetic traits. GSE47756 and GSE44076 datasets were processed with GSEA software to provide a genetic fingertip of different signaling pathways associated with ADIPORs’ mRNA levels. The case–control aspect of the study included the PBMC samples of 73 patients diagnosed with CRC and 80 healthy volunteers. The PCR method was carried out for the PBMC gene expression analysis (ADIPOR1, ADIPOR2, TNF-α mRNA levels) and for the subjects’ genotyping (ADIPOQ rs266729, ADIPOR1 rs7539542). GSEA showed significant associations of ADIPOR mRNA expression with gene sets related to metabolic and immune homeostasis in both datasets. The case–control study revealed the association of ADIPOR1 rs7539542 with reduced lipid status parameters in CRC. In addition, PBMC ADIPOR1 mRNA levels decreased in CRC (p < 0.001), whereas ADIPOR2 mRNA did not differ between the groups (p = 0.442). A reduction in PBMC TNF-α mRNA levels was noted in CRC (p < 0.05). Our results indicate that ADIPOR1 and ADIPOR2 play a significant role in the alteration of both metabolic and immune homeostasis during the progression of CRC. For the first time, ADIPOR1 is shown to be a specific receptor for mediating ADIPOQ’s effects in the PBMCs of CRC patients.

AB  - Objectives: Obstructive sleep apnea (OSA) is a common condition closely related to obesity, insulin resistance, dyslipidemia, and cardiovascular disease. The aim of this study was to explore the possible relationship between OSA and proprotein convertase subtilisin/kexin type 9 (PCSK9). Methods: Full-night polysomnography was performed on 150 participants who were divided into three groups: controls, OSA patients on statin therapy, and OSA patients not on statin therapy. Biochemical markers, plasma low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subclasses, and PCSK9 were determined. Results: PCSK9 was highest in OSA patients on statins compared to the control group and to OSA patients not on statins (p = 0.036 and p = 0.039, respectively), after adjustment for body mass index (BMI). LDL diameter was greater in OSA patients not on statins compared to OSA patients on statins (p = 0.032). PCSK9 was highest in the group of patients with all three risk factors (diagnosed OSA, statins, BMI ≥25 kg/m2) compared to groups with no, one, and two risk factors (p = 0.031, p = 0.001, and p = 0.029, respectively). Presence of OSA, statin therapy, and BMI ≥25 kg/m2 when combined were independently associated with higher levels of PCSK9 when adjusted for antihypertensive therapy, small dense LDL, and HDL 3c subclass (odds ratio = 2.849; interquartile range [1.026–7.912], p = 0.044). Conclusion: Statin therapy was closely related to PCSK9. OSA along with obesity and statin use induces elevation of PCSK9.

AB  - Background and Objectives: Diabetic foot (DF) development is driven by complex interactions of hyperglycemia, inflammation, and oxidative stress (OS). We aimed to investigate OS and inflammatory biomarkers in patients with DF and their potential to improve early diagnosis and management of DF. Materials and Methods: The prooxidant–antioxidant balance (PAB), superoxide dismutase (SOD), total oxidative status (TOS), total sulfhydryl groups (SHG), routine biochemical parameters, and complete blood count were determined in 42 patients with type-2 DM, of which 23 patients had DF, while 19 patients were without DF complications. The neutrophils-to-lymphocyte ratio (NLR) was evaluated as a biomarker of inflammation. Results: Patients with DF had significantly higher (p < 0.05) PAB levels (170 ± 33.9 U/L) compared to those without DF complications (142 ± 31.3 U/L). In addition, patients with DF had significantly reduced SOD activities (p < 0.01). NLR values were significantly higher in the DF group (median: 2.8; interquartile range: 2.0–4.3) than in the group without DF (median: 1.4; interquartile range: 1.4–2.1; p < 0.01). A positive correlation was found between the PAB and NLR index (r = 0.449; p < 0.05). The diagnostic accuracy of both PAB (AUC = 0.741; p < 0.01) and NLR (AUC = 0.760; p < 0.01) was estimated as acceptable. Conclusions: In conclusion, the development of DF is associated with enhanced OS and inflammation processes. PAB and NLR could be useful non-invasive biomarkers of DF development.

AB  - Metabolic disorders in pregnancy, particularly gestational diabetes mellitus (GDM), are associated with an increased risk for adverse pregnancy outcome and long-term cardiometabolic health of mother and child. This study analyzed changes of serum cholesterol synthesis and absorption markers during the course of high-risk pregnancies, with respect to the development of GDM. Possible associations of maternal lipid biomarkers with neonatal characteristics were also investigated. The study included 63 women with high risk for development of pregnancy complications. Size and proportions of small low-density (LDL) and high-density lipoprotein (HDL) particles were assessed across trimesters (T1–T3), as well as concentrations of cholesterol synthesis (lathosterol, desmosterol) and absorption markers (campesterol, β-sitosterol). During the study, 15 women developed GDM, while 48 had no complications (non-GDM). As compared to the non-GDM group, women with GDM had significantly higher triglycerides in each trimester, while having a lower HDL-C level in T3. In addition, they had significantly lower levels of β-sitosterol in T3 (p < 0.05). Cholesterol synthesis markers increased across trimesters in both groups. A decrease in serum β-sitosterol levels during the course of pregnancies affected by GDM was observed. The prevalence of small-sized HDL decreased in non-GDM, while in the GDM group remained unchanged across trimesters. Newborn’s size in the non-GDM group was significantly higher (p < 0.01) and inversely associated with proportions of both small, dense LDL and HDL particles (p < 0.05) in maternal plasma in T1. In conclusion, high-risk pregnancies affected by GDM are characterized by altered cholesterol absorption and HDL maturation. Advanced lipid testing may indicate disturbed lipid homeostasis in GDM.

AB  - Introduction  The aim of this study was to investigate lipoprotein particle distributions and the likelihood of achieving cholesterol homeostasis in the remission phase of nephrotic syndrome (NS) in paediatric patients. We hypothesized that lipoprotein particle distributions moved toward less atherogenic profile and that cholesterol homeostasis was achieved. Materials and methods  Thirty-three children, 2 to 9 years old with NS were recruited. Blood sampling took place both in the acute phase and during remission. Serum low-density lipoprotein particles (LDL) and high-density lipoprotein particles (HDL) were separated using non-denaturing polyacrylamide gradient gel (3-31%) electrophoresis. Serum non-cholesterols sterols (NCSs), desmosterol, lathosterol, 7-dehydrocholesterol (7-DHC), campesterol and β-sitosterol were measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Results  All patients had desirable serum HDL cholesterol concentrations during remission. The dominant lipoprotein diameters and LDL subclass distribution did not change significantly during follow-up. In contrast, HDL lipoprotein particle distribution shifted towards larger particles. The absolute concentration of desmosterol was significantly lower during remission (P = 0.023). β-sitosterol concentration markedly increased during remission (P = 0.005). Desmosterol/β-sitosterol (P < 0.001) and 7-DHC/β-sitosterol (P = 0.005) ratios significantly declined during disease remission. Conclusions  Favourable changes in the serum lipid profiles, HDL particle subclass distribution and cholesterol metabolism in paediatric patients with NS during remission took place. For the first time, we found that cholesterol homeostasis changed in favour of increased cholesterol absorption during disease remission. Nevertheless, complete cholesterol homeostasis was not achieved during disease remission.

AB  - Numerous risk factors have been associated with breast cancer (BC), exposure to metalloestrogen, like lead, being such. Since lead involvement in BC is still equivocal, we focused on lead levels in three compartments of BC patients, blood, healthy, and malignant tissues. Also, as the cholesterol role in cancer development was recognized at the beginning of the twentieth century and led to involvement in lipid profile impairment, we further extend our research on lipid profile and enzymes responsible for maintaining lipid balance in BC patients. Fifty-five women diagnosed with BC were enrolled in the study. Forty-one healthy women represented the control group. Lead levels in blood, healthy surrounding and malignant tissue, and lipid profile parameters in serum, were determined. Higher lead levels were obtained in surrounding healthy tissue samples compared to cancerous tissue samples, while blood lead levels of BC women did not differ significantly from the control group. The altered lipid profile scheme in women diagnosed with breast cancer contained significantly higher triglycerides levels (P < 0.001). Moreover, logistic regression analysis revealed triglycerides as a significant predictor of BC (OR = 2.6; P < 0.01). Although statistical significance was missing for lower paraoxonase-1 (PON-1) activities observed in BC women, multivariate logistic regression singled out PON-1 activities as significant BC predictors. The result of the present study further indicated oxidative status imbalance and tissue levels bioelements perturbation. Obtained results in the present study propose possible lead involvement in BC onset accompanied with bioelements redistribution and oxidative stress occurrence.

AB  - Compelling evidence supports the causative link between increased levels of low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (CVD) development. For that reason, the principal aim of primary and secondary cardiovascular prevention is to reach and sustain recommended LDL-C goals. Although there is a considerable body of evidence that shows that lowering LDL-C levels is directly associated with CVD risk reduction, recent data shows that the majority of patients across Europe cannot achieve their LDL-C targets. In attempting to address this matter, a new overarching concept of a lipid-lowering approach, comprising of even more intensive, much earlier and longer intervention to reduce LDL-C level, was recently proposed for high-risk patients. Another important concern is the residual risk for recurrent cardiovascular events despite optimal LDL-C reduction, suggesting that novel lipid biomarkers should also be considered as potential therapeutic targets. Among them, small dense LDL particles (sdLDL) seem to have the most significant potential for therapeutic modulation. This paper discusses the potential of traditional and emerging lipid-lowering approaches for cardiovascular prevention by targeting sdLDL particles.

AB  - Atherosclerosis is responsible for large cardiovascular mortality in many countries globally. It has been shown over the last decades that the reduction of atherosclerotic progression is a critical factor for preventing future cardiovascular events. Low-density lipoproteins (LDL) have been successfully targeted, and their reduction is one of the key preventing measures in patients with atherosclerotic disease. LDL particles are pivotal for the formation and progression of atherosclerotic plaques; yet, they are quite heterogeneous, and smaller, denser LDL species are the most atherogenic. These particles have greater arterial entry and retention, higher susceptibility to oxidation, as well as reduced affinity for the LDL receptor. Increased proportion of small, dense LDL particles is an integral part of the atherogenic lipoprotein phenotype, the most common form of dyslipidemia associated with insulin resistance. Recent data suggest that both genetic and epigenetic factors might induce expression of this specific lipid pattern. In addition, a typical finding of increased small, dense LDL particles was confirmed in different categories of patients with elevated cardiovascular risk. Small, dense LDL is an independent risk factor for cardiovascular diseases, which emphasizes the clinical importance of both the quality and the quantity of LDL. An effective management of atherosclerotic disease should take into account the presence of small, dense LDL in order to prevent cardiovascular complications.

AB  - The presence of residual cardiovascular disease (CVD) risk is a current dilemma in clinical practice; indeed, despite optimal management and treatment, a considerable proportion of patients still undergo major CV events. Novel lipoprotein biomarkers are suggested as possible targets for improving the outcomes of patients at higher risk for CVD, and their impact on major CV events and mortality have previously been investigated. Innovative antidiabetic therapies have recently shown a significant reduction in atherogenic lipoproteins, beyond their effects on glucose parameters; it has also been suggested that such anti-atherogenic effect may represent a valuable mechanistic explanation for the cardiovascular benefit of, at least, some of the novel antidiabetic agents, such as glucagon-like peptide-1 receptor agonists. This emphasizes the need for further research in the field in order to clearly assess the effects of innovative treatments on different novel biomarkers, including atherogenic lipoproteins, such as small dense low-density lipoprotein (LDL), lipoprotein(a) (Lp(a)) and dysfunctional high-density lipoprotein (HDL). The current article discusses the clinical importance of novel lipid biomarkers for better management of patients in order to overcome residual cardiovascular risk.

AB  - Objective: Polycystic ovary syndrome (PCOS) is associated with altered lipid profile and increased small, dense LDL particles (sdLDL). Considering that paraoxonase 1 (PON1) is an anti-oxidative enzyme located on high-density lipoprotein (HDL) particles, the aim of this study was to investigate the connection between oxidative stress (OS) and PON1 activity with lipoprotein subclasses in PCOS depending on obesity. Methods: In 115 PCOS patients lipoprotein subclasses distributions were determined by gradient gel electrophoresis. OS status was assessed by total oxidative status (TOS), advanced oxidation protein products (AOPP), malondialdehyde (MDA), prooxidant-Antioxidant balance (PAB), total antioxidant status (TAS) and superoxide dismutase (SOD) and PON1 activity. Results: Overweight/obese PCOS patients (n=55) had increased OS compared to normal weight patients (n=60). In addition, overweight/obese group had lower HDL size and higher proportion of HDL 3a subclasses (P<0.05). PAB was in negative correlation with HDL 2a (P<0.001), whereas MDA and SOD correlated positively with HDL 3 subclasses (P<0.05). Serum PON1 activity was positively associated with proportions of PON1 activity on HDL 2b (P<0.05) and 2a (P<0.01), but negatively with the proportion on HDL 3 particles (P<0.01). LDL B phenotype patients had increased TAS, SOD and PON1 activity on HDL 2b, but decreased PON1 activity on HDL 3 subclasses. Conclusion: OS is associated with altered lipoprotein subclasses distribution in PCOS patients. Obesity in PCOS affects the profile of HDL subclasses, reflected through the reduced proportion of PON1 activity on HDL 3 subclasses in the presence of sdLDL particles.

abstract = "Objective: Polycystic ovary syndrome (PCOS) is associated with altered lipid profile and increased small, dense LDL particles (sdLDL). Considering that paraoxonase 1 (PON1) is an anti-oxidative enzyme located on high-density lipoprotein (HDL) particles, the aim of this study was to investigate the connection between oxidative stress (OS) and PON1 activity with lipoprotein subclasses in PCOS depending on obesity. Methods: In 115 PCOS patients lipoprotein subclasses distributions were determined by gradient gel electrophoresis. OS status was assessed by total oxidative status (TOS), advanced oxidation protein products (AOPP), malondialdehyde (MDA), prooxidant-Antioxidant balance (PAB), total antioxidant status (TAS) and superoxide dismutase (SOD) and PON1 activity. Results: Overweight/obese PCOS patients (n=55) had increased OS compared to normal weight patients (n=60). In addition, overweight/obese group had lower HDL size and higher proportion of HDL 3a subclasses (P<0.05). PAB was in negative correlation with HDL 2a (P<0.001), whereas MDA and SOD correlated positively with HDL 3 subclasses (P<0.05). Serum PON1 activity was positively associated with proportions of PON1 activity on HDL 2b (P<0.05) and 2a (P<0.01), but negatively with the proportion on HDL 3 particles (P<0.01). LDL B phenotype patients had increased TAS, SOD and PON1 activity on HDL 2b, but decreased PON1 activity on HDL 3 subclasses. Conclusion: OS is associated with altered lipoprotein subclasses distribution in PCOS patients. Obesity in PCOS affects the profile of HDL subclasses, reflected through the reduced proportion of PON1 activity on HDL 3 subclasses in the presence of sdLDL particles.",

AB  - Insulin resistance, hyperlipidemia, oxidative stress and low-grade inflammation are
mechanisms underlying endothelial dysfunction and atherosclerosis development in non-
pregnant state, but in pregnancy they are adaptive mechanisms responsible for fetal
development without health risks for mothers. A special feature of lipids profile in pregnancy
is increase in high density lipoprotein (HDL) cholesterol concentration. Protective role of
HDL particles resides on its complex composition that goes beyond its cholesterol
concentration and exhibits vasodilatory, antioxidant, anti-inflammatory and
antithrombogenic effects. Even the importance of HDL functionality in pathogenesis of
cardiovascular disease has been investigated and confirmed its role in persevering metabolic
health in pregnancy are almost unexplored. Project "HDL research to improve pregnancy
outcome" investigate the pattern of HDL particle distribution and functionality (HDL-ome)
with different pregnancy outcomes. With the sophisticated analytical methods we determine
HDL-ome in uncomplicated and high-risk pregnancies. We mark the HDL-ome component
with a different pattern of change during high-risk pregnancies and test their potential for
pregnancy complications risk assessment. In this this research we investigate molecular
mechanisms crucial for HDL remodelling during pregnancy and possible associations
between maternal metabolic health during pregnancy and maternal and child health in the
future. Such comprehensive approach will provide a better insight into HDL role in maternal
metabolic health during pregnancy and will open a door for further research in this area.

AB  - Non-enzymatic glycation, oxidative stress (OS) and dyslipidemia are the main
metabolic alterations behind the development of macrovascular
complications (cardiovascular diseases) of diabetes mellitus (DM).
However, clinical relevance of biomarkers of these processes in patients with microvascular
complications (nephropathy, neuropathy, retinopathy) is less understood. Therefore, the aim
of this study was to examine advanced glycation products (AGEs), biomarkers of OS, and
dyslipidemia in 100 DM patients (33 without microvascular complications and 77 with
complications) and 30 subjects without DM. AGEs levels were higher in patients with
complications than in those without complications (median: 5.72; interquartile range: 4.60-
6.54 U/mL vs. median: 4.84; interquartile range: 4.10-5.40 U/L; P<0.05). In addition to
AGEs, the group with diabetic retinopathy had higher plasma total antioxidant capacity
(P<0.05), while the group with diabetic nephropathy had smaller LDL size than the patients
without these complications (25.48±1.26 nm vs. 26.21±1.19 nm; P<0.05). The patients
with co-existing cardiovascular disease were further characterized by dysfunctional HDL
particles, as evidenced by increased small HDL particles (P<0.05) and reduced paraoxonase-
1 activities. Significant increase in both pro-oxidant-antioxidant balance and ischemia-
modified albumin (P<0.05), with simultaneously decreased activity of superoxide-dismutase
(P<0.05) was found in patients with progressive diabetic neuropathy, indicating the highest
degree of oxidative damage. It can be concluded that patients with microvascular
complications of DM have aggravated redox imbalance and lipid profile alterations. In
addition to metabolic control, strategies aimed at lowering OS and correcting dyslipidemia
can contribute to the prevention of microvascular complications of diabetes.

dijabetesa melitusa (DM). Međutim, klinički značaj određivanja biomarkera ovih procesa
kod pacijenata sa mikrovaskularnim komplikacijama (retinopatija, nefropatija, neuropatija)
nije dovoljno razjašnjen. Cilj ovog istraživanja je bio ispitivanje produkata uznapredovale
glikacije (AGE), biomarkera OS i dislipidemije kod 100 pacijenata sa DM (33 bez
mikrovaskularnih komplikacija i 77 sa komplikacijama) i 30 ispitanika bez DM. Nivo
cirkulišućih AGE je bio značajno viši u grupi pacijenata sa komplikacijama (medijana: 5,72;
interkvartilni raspon: 4,60-6,54 U/mL) u odnosu na pacijente bez komplikacija (medijana:
4,84; interkvartilni raspon 4,10-5,40 U/L; P<0,05). Pored povišenih koncentracija AGE,
pacijenti sa dijabetesnom retinopatijom su imali i povišene vrednosti totalnog oksidativnog
statusa (P<0,05), a pacijenti sa dijabetesnom nefropatijom manje dijametre LDL čestica
(25,48±1,26 nm) u poređenju sa sa pacijentima bez komplikacija (26,21±1,19 nm;
P<0,05). Nadalje, kod pacijenata sa pridruženim makrovaskularnim komplikacijama
(kardiovaskularnim bolestima) utvrđeno je prisustvo disfunkcionalnih HDL čestica, na
osnovu povećanog udela malih HDL čestica (P<0.05) i smanjene aktivnosti paroksonaze-
1. Pacijenti sa progresivnom dijabetesnom neuropatijom su imali značajno povišene
vrednosti prooksidativno-antioksidativnog balansa i ishemijom modifikovanog albumina
(P<0,05), uz istovremeno sniženje aktivnosti superoksid-dismutaze (P<0,05), što ukazuje da
je stepen oksidativnog oštećenja u ovoj grupi bio najveći. Može se zaključiti da, pored
adekvatne metaboliče kontrole, strategije usmerene ka sniženju OS i korekciji dislipidemije,
mogu doprineti prevenciji razvoja mikrovaskularnih komplikacija dijabetesa.
