OBJECTIVE(S): The aim of our study is to analyse the inflammatory markers and lipid accumulation product (LAP) index in nonobese adolescents and younger aged women with polycystic ovary syndrome (PCOS) compared with age and body mass index (BMI)-matched healthy controls and to determine whether the investigated parameters are potential markers for the etiopathogenesis of PCOS. We also aim to determine whether these inflammatory markers are predictive for developing some clinical implications, such as cardiovascular disease (CVD) and insulin resistance (IR), associated with PCOS...

Angiotensin II, one of the rennin-angiotensin system components, is important in the cardiovascular hemodynamic and plays an important role in the development of cardiovascular disease in systemic lupus erythematosus (SLE) patients. The angiotensin II, through interaction with angiotensin II type 1 receptor (AGTR1), promotes proliferation, inflammation and fibrosis. The single nucleotide polymorphism of the AGTR1 (dbSNP: rs5186) gene can be associated with development and progression of SLE disease. The aims of this study were to compare the frequency of AGTR1 rs5186 in SLE patients with healthy individuals and to evaluate possible association between AGTR1 A1166C gene polymorphism and serum level of lipids, neopterin and malondialdehyde in SLE patients from a population of West Iran...

Bipolar disorder (BD) is a recurrent, episodic mood disorder for which there are no current diagnostic, prognostic or theranostic biomarkers. Two peripheral markers of the acute phase immune response, zinc and neopterin, are consistently associated with severity of depression in literature. Given gender differences in clinical presentation of BD and in inflammatory processes, we aimed to explore the interaction between gender and immune biomarkers to predict mood severity in BD. Participants with DSM IV BD I and II were recruited through the Pennsylvania Psychiatric Institute during an acute mood episode...

Aging is associated with a decline in the normal functioning of the immune system. Several studies described the relationship between immunological alterations, including immunosenescence and inflammation, and aging or age-related outcomes, such as sarcopenia, depression, and neurodegenerative disorders. Physical activity is known to improve muscle function and to exert a number of benefits on older adult health, including reduced risk for heart and metabolic system chronic diseases. However, the positive influence of physical activity on the immune system has not been elucidated...

Experimental models of bullous pemphigoid (BP), the most frequent subepidermal autoimmune bullous disease, revealed that the immune response leading to blister formation represents an incompletely understood complex process involving different inflammatory cells. In contrast to previous reports commonly focusing on limited molecular and cellular phenotypes of the disease, the aim of this study was to investigate a broad spectrum of markers of cellular immune activation in patients with BP. We found that serum levels of soluble CD4, myeloperoxidase, S100A12, eosinophil cationic protein, and soluble P-selectin were significantly elevated in patients with active BP compared with normal controls...

INTRODUCTION: Neopterin and biopterin are sub-products of redox reactions, which act as cofactors of enzymes responsible for nitric oxide production. The hypothesis is presented that plasma neopterin and biopterin evolve differently during the first days in a critically ill child. METHODS: A single-centre prospective observational study was conducted on patients 7 days to 14 years admitted to our Paediatric Intensive Care Unit (PICU) and that met Systemic inflammatory response syndrome (SIRS) criteria...

BACKGROUND: Sepsis is one of the most common causes of hospitalization and it is characterized by a high mortality rate in spite of the great progress in diagnosis and treatment achieved in recent years. Early diagnosis of sepsis is one of the most important elements of effective treatment. The clinical symptoms are not specific and biomarkers are considered to be useful tools in sepsis diagnostics. OBJECTIVES: The aim of our study was to evaluate the diagnostic value of sCD163 as a marker of sepsis and a comparison of it with procalcitonin and neopterin in ICU patients...

BACKGROUND: Environmental enteropathy (EE), the adverse impact of frequent and numerous enteric infections on the gut resulting in a state of persistent immune activation and altered permeability, has been proposed as a key determinant of growth failure in children in low- and middle-income populations. A theory-driven systems model to critically evaluate pathways through which enteropathogens, gut permeability, and intestinal and systemic inflammation affect child growth was conducted within the framework of the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) birth cohort study that included children from eight countries...

In 1984, we started using therapeutic plasmapheresis (plasma exchange) as a method of extracorporeal lipoprotein elimination for the treatment of hypercholesterolemic patients. We evaluated the results of long-term therapy in 14 patients, 8 men and 6 women. The average age was 55.6+/-13.2 (range 28-70), median 59.5 years. 14 patients were diagnosed with familial hypercholesterolemia (FH): 5 homozygous, 9 heterozygous. Ten patients in the group were treated using immunoadsorption lipoprotein apheresis and 4 using hemorheopheresis...

The role of CD36 in oxidised low-density lipoprotein (oxLDL) mediated cell death was examined by down regulating the receptor level with the macrophage generated antioxidant 7,8-dihydroneopterin. Down regulation of CD36 protein levels in human monocyte derived macrophages by 7,8-dihydroneopterin corresponded to a decrease in CD36-mRNA. The oxidation products of 7,8-dihydroneopterin, dihydroxanthopterin and neopterin did not significantly down regulate CD36. The CD36 down regulation resulted in a decrease in oxLDL uptake measured as 7-ketocholesterol accumulation...
