BACKGROUND: Cerebrospinal fluid (CSF) is an essential bio-fluid of the central nervous system (CNS), playing a vital role in the protection of CNS and performing neuronal function regulation. The chemical composition of CSF varies during onset of meningitis, neurodegenerative disorders (positive controls) and in traumatic cases (negative controls). METHODS: The study design was broadly categorized into meningitis cases, negative controls and positive controls. Further differentiation among the three groups was carried out using Principal Component Analysis (PCA) followed by supervised Partial Least Square Discriminant Analysis (PLS-DA)...

BACKGROUND: Malnutrition hastens progression to Acquired Human Immunodeficiency Syndromes (AIDS) related illnesses; undermines adherence and response to antiretroviral therapy (ART) in resource-poor settings. However, nutritional status of people living with HIV (PLHIV) can be affected by various psychosocial factors which have not been well explored in Ethiopia. Therefore, the objective of this study was to determine psychosocial correlates of nutritional status among people living with HIV (PLHIV) on ART in Central zone of Tigray, Northern Ethiopia...

BACKGROUND: More cost-effective HIV control may be achieved by targeting geographical areas with high infection rates. The AIDS Impact model of Spectrum - used routinely to produce national HIV estimates - could provide the required subnational estimates but is rarely validated with empirical data, even at a national level. DESIGN: The validity of the Spectrum model estimates were compared with empirical estimates. METHODS: Antenatal surveillance and population survey data from a population HIV cohort study in Manicaland, East Zimbabwe, were input into Spectrum 5...

Gilbert syndrome (GS) is a frequent benign clinical condition, marked by intermittent unconjugated hyperbilirubinemia, mostly due to the polymorphism uridine diphosphate-glucuronosyltransferase 1A1*28 (UGT1A1*28). Hyperbilirubinemia has been reported in a GS patient undergoing hepatitis C treatment, and other UGT isoforms polymorphisms have been linked to worse outcomes in viral hepatitis. Yet, little is known to GS contributions' to the liver disease scenario. Our aim was to assess UGT1A1 genotypes' frequency in chronic hepatitis C (CHC) patients and correlate with total bilirubin (TB)...

Drug-induced liver injury (DILI) is a known adverse effect of both anti-tuberculosis (anti-TB) and antiretroviral (ARV) drugs. Recent studies highlight the implications of genetic predispositions to DILI. We performed a case-control study to identify Human Leukocyte Antigen-B (HLA-B) variant alleles associated with anti-TB and ARV co-treatment induced liver toxicity in Ethiopian TB and HIV co-infected patients. A total of 495 newly diagnosed TB and HIV co-infected patients were enrolled and received rifampicin based anti-TB and efavirenz based ARV therapy...

BACKGROUND: Routes of transmission of multidrug-resistant gram-negative organisms (MDRGN) are not completely understood. Since sexual transmission of MDRGN might represent a potential mode that has not been noticed so far, this study evaluated transmission of MDRGN in HIV positive men. METHODS: Between November 2014 and March 2016, we retrospectively investigated the MDRGN prevalence in rectal swabs of n = 109 males tested positive for HIV (HP). These findings were compared to the MDRGN prevalence in n = 109 rectal swabs in age-matched males tested negative for HIV (HN) within the same period...

We evaluated IL-10 -592 C/A, IL-4 -589 C/T, IFN-γ +874 A/T, CTLA-4 +49 A/G gene polymorphisms in efavirenz hypersensitivity reaction. A total of 63 HIV-positive patients under treatment at a public hospital were included in the study, of which 21 presented efavirenz hypersensitivity. Patients who presented efavirenz hypersensitivity reaction showed a higher frequency of the IL-10 -592A allele than the controls (p = 0.028). The allele A was associated with increased risk to efavirenz hypersensitivity (OR = 2...

BACKGROUND: Considering the remarkable efficacy of the strategies for preventing mother-to-child transmission of HIV infection (PMTCT), failures are rare in high-resource countries and deserve further investigation. Moreover, infants have been found to be at increased risk of viral failure. We analyzed the factors related to the children's environment, including maternal psychological factors that may be associated with viral failure in children diagnosed before the age of 1 year. PATIENTS AND METHODS: Retrospective study of all HIV-infected infants, born in France between July 2003 and July 2013, diagnosed before the age of 1 year, cared for in a single reference center, comparing the group of children in viral success to the group of children presenting at least one episode of viral failure, using data available in their medical, psychological and social files...

BACKGROUND: Young children bear the world's highest prevalence of anaemia, the majority of which is of multifactorial aetiology, which in turn hampers its successful prevention. Even moderate degrees of anaemia are associated with increased mortality and morbidity. Despite this evidence, there is a lack of effective preventive programs and absence of consensus in the safety of iron supplementation in malaria areas, which reflects the poor understanding of the contribution of different aetiologies to anaemia...

BACKGROUND: No published randomised controlled data on the use of direct acting antivirals (DAA) in acute hepatitis C (AHC) coinfection exist. However, with the AHC epidemic ongoing among men who have sex with men (MSM) these are urgently needed. METHODS: The CHAT study is a randomised controlled trial of pegylated interferon + ribavirin (PR) plus telaprevir (TVR) for 12-24 weeks versus PR alone for 24-48 weeks in the response guided treatment of patients with AHC genotype (GT) 1 infection and HIV-1 co-infection in Germany and Great Britain...

Recurrent tuberculosis is an important indicator of the effectiveness of tuberculosis control and can occur by relapse or exogenous reinfection. We conducted a retrospective cohort study on all bacteriologically confirmed tuberculosis cases that were successfully treated between 2000 and 2012 in Shanghai, an urban area with a high number but a low prevalence rate of tuberculosis cases and a low prevalence of HIV infection. Genotyping the Mycobacterium tuberculosis from clinical isolates was used to distinguish between relapse and reinfection...

Depression is a leading cause of HIV/AIDS disease burden; it worsens health outcomes and quality of life. Addressing this problem requires accurate quantification of the extra burden of depression to HIV/AIDS in a given population, and knowledge of the baseline depression prevalence in the general population. There has been no previous study of depression in the general Cameroonian population. The current study attempts to address that important need. We used the Beck Depression Inventory-II to assess the prevalence and severity of depressive symptoms in 270 HIV-infected and seronegative Cameroonians...

Ending the HIV epidemic needs additional methods to better assess the incidence and prevalence of HIV infection. In this study, a new indicator - G-rate was developed for the evaluation of HIV epidemics across regions with regard to geographic area size. Different from the commonly used incidence and prevalence rates that assess the HIV epidemic with reference to population (termed as P rate in this study), G rate measures the number of new infections (incidence) or cases (prevalence) over a unit land area in one year...
