Highly active antiretroviral therapy (HAART) is known to cause lipid abnormalities such as dyslipidaemia in HIV-infected individuals. Yet, dyslipidaemia may not independently occur as it may be worsened by single nucleotide polymorphisms (SNPs) in lecithin cholesterol acyltransferase (LCAT) and lipoprotein lipase (LPL). This case–control study was conducted in three-selected hospitals in the Northern part of Ghana. The study constituted a total of 118 HIV-infected participants aged 19–71 ...
Abstract Alcohol has particularly harmful health effects in HIV-infected patients; therefore, HIV clinics are an important setting for integration of routine alcohol screening as an integral component of HIV care.In sub-Sahara Africa, little is known about AUDs among people attending HIV services. Objective: To estimate the prevalence of alcohol use disorder in patients attending CCC at KNH Design: A descriptive cross-sectional study Setting: Comprehensive Care Center, Kenyatta National Hosp...
Abstract Ethnopharmacological relevance Medicinal plants play a major role in many communities across the world, in the treatment and prevention of disease and the promotion of general health. The aim of the study was to escalate documentation from an earlier study of medicinal plants, traditionally used to combat malaria by the Ameru community of Imenti Forest area and Gatunga in Eastern Region of Kenya, and validate their ethnopharmacological claims by evaluating their antiplasmodial effic...
Abstract Background Although injection drug use drives antiretroviral drug resistance, the prevalence of protease inhibitor (PI) resistance among Kenyan IDUs remains undetermined. We, therefore, explored PI resistance mutations and their association with viral load and CD4+ T cell counts in HIV-1 infected IDUs (ART-naive, n = 32; and -experienced, n = 47) and non-drug users (ART-naive, n = 21; and -experienced, n = 32) naive for PI treatment from coastal Kenya. Results Only IDUs harboured ma...
Abstract Introduction: the interaction between Mycobacterium tuberculosis and HIV leads to rapid progression of tuberculosis (TB) and human immunodeficiency virus (HIV)-induced immunosuppression. Diagnosis of TB in these patients is more difficult due to its atypical presentations giving contradicting results. The overall aim of this study was to evaluate the ability of pro-inflammatory cytokine (Th1) and anti-inflammatory cytokine (Th2) to discriminate between culture-positive and -negative...
Abstract Background Improved understanding of the molecular mechanisms involved in pediatric severe malarial anemia (SMA) pathogenesis is a crucial step in the design of novel therapeutics. Identification of host genetic susceptibility factors in immune regulatory genes offers an important tool for deciphering malaria pathogenesis. The IL-23/IL-17 immune pathway is important for both immunity and erythropoiesis via its effects through IL-23 receptors (IL-23R). However, the impact of IL-23R v...
Abstract An understanding of the immunogenetic basis of naturally acquired immunity to Plasmodium falciparum infection would aid in the designing of a rationally based malaria vaccine. Variants within the Fc gamma receptors (FcγRs) mediate immunity through engagement of immunoglobulin G and other immune mediators, such as gamma interferon (IFN-γ), resulting in erythrophagocytosis and production of inflammatory cytokines in severe malarial anemia (SMA). The Toll-like receptors (TLRs) trigge...

Abstract In holoendemic Plasmodium falciparum transmission areas such as western Kenya, severe malarial anemia [SMA,hemoglobin (Hb) < 6.0 g/dL, with any density parasitemia] is the most common clinical manifestation of severe malariaresulting in high rates of pediatric morbidity and mortality in these regions. Previous studies associated interleukin (IL)-13with pathogenesis of different infectious diseases, including P. falciparum malaria. However, the functional roles ofpolymorphic variants...
Abstract Mycobacterium tuberculosis, a Gram-positive bacterium of great clinical relevance, is a lethal pathogen owing to its complex physiological characteristics and development of drug resistance. Several molecular genetic tools have been developed in the past few decades to study this microorganism. These tools have been instrumental in understanding how M. tuberculosis became a successful pathogen. Advanced molecular genetic tools have played a significant role in exploring the complex ...
Aims: The involvement of maternal sociodemographic, obstetric, clinical, anthropometric and biochemical variables in preeclampsia has been demonstrated in previous studies. However, there are intra- and inter-population variabilities in study findings due to differences in genetic and environmental factors. This requires population-specific studies to aid the formulation of local protocols for the early detection and management of preeclampsia. Study Design: This was a case-control study Pl...
Abstract: Objective: To evaluate the insecticide, larvicidal and repellent activity of the essential oils from Callistemon viminalis, Melaleuca leucadendron, and Hyptis suaveolens against Chrysodeixis chalcites and to compare it with neem oil (Azadirachta indica). Methods: The essential oils of the leaves of these aromatiques plants were extracted by steam distillation and contacts tests were carried out. Results: Essential oils in ethanol from Callistemon viminalis showed a higher biologica...
Background: Blood glucose measurement is a way of monitoring changes in glycaemia. Different point-of-care testing (POCT) glucose meters are on the market and hence there is an increase in variability of the results given by these meters. This study sought to measure the glycaemic variability using four different point-of-care glucose meters Methods: Four point of care glucometers namely; Accu-chek performer nano, OneTouch select plus flex, OneTouch Ultra 2 and Easy Check were used test blood...
Background: The onset of preeclampsia (PE) may be early (EOPE), or late (LOPE). Preeclampsia may also be characterized by severe features (PS) or without severe features (PNS). This study aimed to predict the onset and severity of PE using biomarkers including neutrophil gelatinase-associated lipocalin (sNGAL) and endothelin-1 (ET-1). Method: This was a case-control study from January to June 2020. The study involved 270 pregnant women (control=135, PE=135), aged between 18-37 years. The case...
Prenatal hormone exposure has been suggested as a correlate of adult circulating estrogen and testosterone. If this observation is true, then prenatal hormone exposure may have an association with lipid homeostasis in adulthood. The study sought to investigate sexual dimorphism and the interactions between the putative marker of prenatal hormone exposure (2D : 4D) and sex on adult fasting plasma lipid variables. The study was cross-sectional from June to December 2021 at the University for De...
