Early sexual debut is associated with drug use and decreased educational attainment among males and females in Kisumu County, Kenya.

Differing global sociocultural contexts of sexual relationships influence age at first sexual intercourse with potentially long-lasting region-specific effects such as increased risk of contracting HIV and other sexually transmitted infections (STIs). In these cross-sectional analyses of data from the screening and enrollment visits for an HIV incidence study in Kisumu County, Kenya, we evaluated factors associated with having experienced an early sexual debut (ESD) among males and females aged 18-35 years. Clinical evaluation was performed and sexual behaviors were assessed via questionnaire.

Safety and immunogenicity of a purified inactivated Zika virus vaccine candidate in adults primed with a Japanese encephalitis virus or yellow fever virus vaccine in the USA: a phase 1, randomised, double-blind, placebo-controlled clinical trial.

Background: Zika virus infection is a threat to at-risk populations, causing major birth defects and serious neurological complications. Development of a safe and efficacious Zika virus vaccine is, therefore, a global health priority. Assessment of heterologous flavivirus vaccination is important given co-circulation of Japanese encephalitis virus and yellow fever virus with Zika virus.

Initiation of anti-retroviral/Trimethoprim-Sulfamethoxazole therapy in a longitudinal cohort of HIV-1 positive individuals in Western Kenya rapidly decreases asymptomatic malarial parasitemia.

Interactions between malaria and HIV-1 have important public health implications. Our previous cross-sectional studies showed significant associations between HIV-1 positivity and malarial parasitemia with an increased risk of gametocytemia. In this follow-up longitudinal study, we evaluated these associations to determine the magnitude of asymptomatic parasitemia over time, and to examine the effects of initiating Antiretroviral Therapy (ART) together with the broad-spectrum antibiotic Trimethoprim Sulfamethoxazole (TS) on asymptomatic parasitemia.

Longitudinal and Cross-sectional Analyses of Asymptomatic HIV-1/Malaria Co-infection in Kisumu County, Kenya.

Individuals infected with HIV-1 experience more frequent and more severe episodes of malaria and are likely to harbor asymptomatic parasitemia, thus potentially making them more efficient reservoirs of malaria. Two studies (cross-sectional and longitudinal) were designed in sequence between 2015-2018 and 2018-2020, respectively, to test the hypothesis that HIV-1 infected individuals have higher prevalence of asymptomatic parasitemia and gametocytemia than the HIV-1 negatives. This article describes the overall design of the two studies, encompassing data for the longitudinal study and additional data to the previously published baseline data for the cross-sectional study.

Brief Report: Increased Inflammation and Liver Disease in HIV/HBV-Coinfected Individuals.

Objective: HIV and hepatitis B virus (HBV) coinfection can accelerate morbidity and mortality, especially in sub-Saharan Africa where both infections are common. Although inflammation contributes to disease progression, more information is needed to better understand the pathology. This study compared markers of cirrhosis and inflammation in HIV/HBV-coinfected individuals compared with monoinfected and uninfected patients.

Clinical laboratory reference values in adults in Kisumu County, Western Kenya; hematology, chemistry and CD4.

Background: Clinical laboratory reference intervals (RIs) are essential for diagnosing and managing patients in routine clinical care as well as establishing eligibility criteria and defining adverse events in clinical trials, but may vary by age, gender, genetics, nutrition and geographic location. It is, therefore, critical to establish region-specific reference values in order to inform clinical decision-making.

Methods: We analyzed data from a prospective observational HIV incidence cohort study in Kombewa, Kenya.

Asymptomatic Visceral Leishmania infantum Infection in US Soldiers Deployed to Iraq.

Background: Visceral leishmaniasis (VL), due to Leishmania infantum, is a persistent intracellular parasitic infection transmitted by the bite of infected sand flies. Symptomatic VL has been reported in U.S.

Methicillin-Resistant as a Probable Cause of Antibiotic-Associated Enterocolitis.

Antibiotic-associated diarrhea is typically associated with . However, has also been described as a cause of antibiotic-associated enterocolitis and diarrhea and is likely an underrecognized etiology. We present a case of enterocolitis and urinary tract infection caused by methicillin-resistant following antibiotic treatment.

An Adverse Drug Reaction to Trimethoprim-Sulfamethoxazole Revealing Primary HIV: A Case Report and Literature Review.

Adverse drug reactions (ADRs) to antibiotics complicate the management of any infection, particularly opportunistic infections in advanced HIV as some ADRs are potentiated by HIV. Trimethoprim-sulfamethoxazole (TMP-SMX) causes ADRs in 40-80% of HIV infected individuals, compared to 3-5% in the general population. The incidence and severity of ADRs among HIV infected individuals appear to increase as they progress from latent infection to AIDS.

Leishmaniasis: treatment updates and clinical practice guidelines review.

Purpose Of Review: This review summarizes recent important and interesting articles investigating the challenging treatment of the parasitic infection, leishmaniasis. In addition, it compares and contrasts leishmaniasis clinical practice treatment guidelines.

Recent Findings: Studies show that, in contrast to experience in India, visceral leishmaniasis in East Africa requires higher doses of liposomal amphotericin for effective treatment results and that pentavalent antimonial drugs remain efficacious.

Ciguatera fish poisoning in Hawai'i and the Pacific.

Ciguatera fish poisoning (CFP) is a foodborne illness caused by fish containing ciguatoxin (CTX). The toxin is produced by the microalgae Gambierdiscus spp. which are then eaten by reef fish; humans contract the illness when eating either fish that have eaten the algae, or carnivorous fish that have eaten those fish.

Mycobacterium haemophilum Masquerading as Leprosy in a Renal Transplant Patient.

Opportunistic infections following immunosuppression in solid organ transplant (SOT) patients are common complications with the skin being a common sight of infection. Nontuberculous mycobacteria (NTM) are rare but potential causes of skin infection in SOT patients. We present a case of an adult male immunosuppressed following renal transplantation who presented with an asymptomatic rash for several months.
