Neurocognitive profile in HIV subjects on INSTI-regimen- one year follow up: Is there room for optimism?

The introduction of antiretroviral therapy (ART) has successfully changed the clinical course of people with HIV, leading to a significant decline in the incidence of HIV-related neurocognitive disorders. Integrase strand transferase inhibitors (INSTI) are recommended and preferred first-line ART for the treatment of HIV-1 infection in ART-naïve subjects. This type of therapy regimen is expected to have higher CNS penetration, which may bring more cognitive stability or even make significant cognitive improvement in people with HIV.

Additive Effect of Metabolic Syndrome on Brain Atrophy in People Living with HIV-Magnetic Resonance Volumetry Study.

With people living with HIV (PLWH) reaching the senium, the importance of aging-related comorbidities such as metabolic syndrome (MS) becomes increasingly important. This study aimed to determine the additive effect of MS on brain atrophy in PLWH. This prospective study included 43 PLWH, average age of 43.

Sagittal Abdominal Diameter as the Best Predictor of Metabolic Syndrome in HIV-Infected Men on Antiretroviral Therapy.

Background: The interaction of human immunodeficiency virus (HIV), host and antiretroviral therapy (ART) causes a range of metabolic disorders that can be characterized as a metabolic syndrome (MetS) that increases the cardiovascular risk. MetS involves central obesity, which can be detected using different anthropometric parameters.

Objective: To assess the abilities of different anthropometric parameters in the prediction of MetS in HIV-infected men on ART.

Relation of Steatosis to Neurocognitive Function in People Living with HIV.

Background: In HIV negative population metabolic syndrome and steatosis are related to poorer neurocognitive (NC) performance. We investigated if similar relation exists in people living with HIV (PLWH).

Methods: We included male PLWH aged 20-65, with undetectable viral load for at least 6 months.

Associations of visceral fat thickness and anthropometric measurements with non-alcoholic fatty liver disease development in male patients mono-infected with human immunodeficiency virus.

Background: Non-alcoholic fatty liver disease (NAFLD) represents the most common form of chronic liver disease in mono-infected (without concomitant hepatitis B and/or C virus infection) people living with human immunodeficiency virus (HIV). The proper and on time identification of at-risk HIV-positive individuals would be relevant in order to reduce the rate of progression from NAFLD into non-alcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma.

Objectives: The aim of this study was to explore visceral fat thickness (VFT) and anthropometric measurements associated with the development of NAFLD in patients mono-infected with HIV and on long-standing combination antiretroviral therapy (cART).

Executive Functions Rating Scale and Neurobiochemical Profile in HIV-Positive Individuals.

The set of complex cognitive processes, that are necessary for the cognitive control of behavior, known as executive functions (EF), are traditionally associated with the prefrontal cortex and commonly assessed with laboratory based tests and conventional neuroimaging. In an effort to produce a more complete and ecologically valid understanding of executive functioning, the rating scales have been developed in order to assess the behavioral aspects of EF within an everyday real-world context. The main objective of this study was to examine the relationship between behavioral aspects of EF measured by rating scale and neurometabolic profile in neurologically asymptomatic HIV-positive individuals under cART, measured using multi-voxel magnetic resonance spectroscopy (mvMRS).

Neuroendocrine disorder in chronic fatigue syndrome.

Background/aim: Neuroendocrine disorders are considered a possible pathogenetic mechanism in chronic fatigue syndrome (CFS). The aim of our study was to determine the function of the hypothalamic-pituitary-adrenal axis (HPA) and thyroid function in women of reproductive age suffering from CFS. Materials and methods: The study included 40 women suffering from CFS and 40 healthy women (15-45 years old).

Neurocognitive profile of HIV-positive adults on combined antiretroviral therapy: A single-centre study in Serbia.

The advent of combined antiretroviral therapy (cART) has prolonged the life expectancy of HIV + individuals and decreased the incidence of HIV-associated dementia. However, milder forms of neurocognitive impairment remain common and are often associated with poor daily functioning and lower medication adherence. This paper presents a research aimed at exploring the cognitive status differences between HIV + subjects (N = 39) on cART therapy and a group of demographically comparable healthy subjects (N = 39) in Serbia.

Non-cirrhotic Portal Hypertension Associated with Didanosine and Streptococcus agalactiae Infection: A Case Report.

Background: Non-Cirrhotic Portal Hypertension (NCPH) is a rare but potentially fatal liver disorder described in patients treated with anti-retroviral therapy for Human Immunodeficiency Virus (HIV). In particular, the most important predisposing factor to its development has been identified as prolonged exposure to Didanosine (ddI). The clinical entity of NCPH is characterized by an increase in portal pressure due to pre- or intra-hepatic causes, in absence of liver cirrhosis.

Prediction of brain atrophy using three drug scores in neuroasymptomatic HIV-infected patients with controlled viremia.

Background: Despite potent antiretroviral therapy, HIV still causes brain damage. Better penetration into the CNS and efficient elimination of monocyte/macrophages reservoirs are two main characteristics of an antiretroviral drug that could prevent brain damage. The aim of our study was to assess efficacy of three antiretroviral drug scores to predict brain atrophy in HIV-infected patients.

Multivitamin mineral supplementation in patients with chronic fatigue syndrome.

Background: Chronic fatigue syndrome (CFS) is characterized by medically unexplained persistent or reoccurring fatigue lasting at least 6 months. CFS has a multifactorial pathogenesis in which oxidative stress (OS) plays a prominent role. Treatment is with a vitamin and mineral supplement, but this therapeutic option so far has not been properly researched.

Adaptation of marine plankton to environmental stress by glycolipid accumulation.

A systematic investigation of non-phosphorus containing glycolipids (GL) was conducted in the northern Adriatic Sea during two years at two stations with different nutrient loads. GL concentration varied both spatially and temporally, with values of 1.1-21.

Lipid and protein oxidation in female patients with chronic fatigue syndrome.

Introduction: Chronic fatigue syndrome (CFS) is a widely recognized problem, characterized by prolonged, debilitating fatigue and a characteristic group of accompanying symptoms, that occurs four times more frequently in women than in men. The aim of the study was to determine the existence of oxidative stress and its possible consequences in female patients with CFS.

Material And Methods: Twenty-four women aged 15-45 who fulfilled the diagnostic criteria for CFS with no comorbidities were recruited and were age matched to a control group of 19 healthy women.

Minimal hepatic encephalopathy in patients with decompensated liver cirrhosis.

Minimal hepatic encephalopathy (mHE) is characterized by some minimal unspecific alterations of cerebral functions that can only be detected by neuropsychological or neurophysiological diagnostic tests, which dysfunctions nevertheless interfere with the patient's daily living. Early recognition of these impairments may prevent the progression or delay the development of the disease to overt hepatic encephalopathy. The aim of this study was to diagnose mHE in patients with decompensated liver cirrhosis.

Thiobarbituric acid reactive substances as marker of oxidative stress in pregnancies with pre-eclampsia.

Pre-eclampsia is characterized by increased lipid peroxidation and diminished antioxidant capacity. The aim of the study was to establish concentration of thiobarbituric acid reactive substances as a marker of lipid peroxidation in normal pregnancies and in pregnancies complicated with pre-eclampsia, and to estimate the possibility of using thiobarbituric acid reactive substances as a screening method for development of pre-eclampsia. The study was conducted at the Department of Obstetrics and Gynaecology, Clinical Centre of Vojvodina.

Cystatin C in pre-eclampsia.

Objective: To evaluate diagnostic value of cystatin C serum levels as alternative marker of renal function in pre-eclamsia (PE) and compare it with the traditional markers of renal function, creatinine and uric acid. In order to investigate the possible influence of inflammation on biochemical markers of renal function, serum levels of high sensitive CRP were measured (hsCRP).

Methods: In this prospective study markers of kidney function were investigated in two groups of pregnant women: one with PE (n = 32) and the other of healthy pregnant women (n = 60).

Chronic fatigue syndrome.

Chronic fatigue syndrome (CFS) is defined by a profound, debilitating fatigue, lasting for at least 6 months and resulting in a substantial reduction of occupational, personal, social and educational status. CFS is a relatively poorly recognized clinical entity, although everyday experience shows that there are many patients with CFS symptoms. The incidence and prevalence of CFS remain unknown in most countries; however, the working population is most affected with predominantly female patients in generative period.
