Subacute sclerosing panencephalitis is a fatal infectious disease of childhood caused by persistence of the measles virus in the brain. The effect of human immunodeficiency virus (HIV) co-infection on subacute sclerosing panencephalitis remains elusive and rare. We report a child who developed subacute sclerosing panencephalitis following a short latency period and a rapidly progressive course with HIV co-infection.

BACKGROUND: The therapy of visceral leishmaniasis (VL) is limited by resistance, toxicity and decreased bioavailability of the existing drugs coupled with dramatic increase in HIV-co-infection, non-availability of vaccines and down regulation of cell-mediated immunity (CMI). Thus, we envisaged combating the problem with plant-derived antileishmanial drug that could concomitantly mitigate the immune suppression of the infected hosts. Several plant-derived compounds have been found to exert leishmanicidal activity via immunomodulation...

Tumor necrosis factor (TNF) is a key cytokine in HIV replication and pathogenesis. For reasons that are not entirely clear, the cytokine remains upregulated despite anti-retroviral therapy (ART). Here we demonstrate that HIV Nef induces an alternative TNF secretion mechanism that remains active in chronic infection. Ingestion of Nef-containing plasma extracellular vesicles (pEV) from ART patients by primary immune cells, but also Nef expression, induced intracellular proTNF cleavage and secretion of vesicular TNF endosomes...

Patients infected with human immunodeficiency virus (HIV) are living longer, healthier lives on highly active antiretroviral therapy and, as a result, interest in kidney transplantation for HIV-infected patients with end-stage renal disease has increased. HIV is no longer considered a contraindication to solid-organ transplantation and the number of kidney transplants performed in HIV-infected patients each year is increasing steadily. HIV-infected kidney transplant recipients have had excellent outcomes overall, but there are still significant challenges, including high rates of acute rejection, drug-drug interactions, and poor outcomes in patients co-infected with hepatitis C virus...

BACKGROUND: HBV and HIV share similar transmission routes. Concurrent infection with the two viruses usually results in more severe and progressive liver disease, and a higher incidence of cirrhosis, liver cancer and mortality. Further, this co-infection may lead to cross-resistance between HIV and HBV drugs and increased liver injury, either due to direct hepatotoxicity or drug-related immune-reconstitution hepatitis. These challenges necessitate continuous surveillance for HBV among HIV infected individuals to guide patient management...

BACKGROUND: According to the World Health Organization, South Africa ranks as one of the highest burden of TB, TB/HIV co-infection, and drug-resistant TB (DR-TB) countries. DR-TB treatment is complicated to administer and relies on the use of multiple toxic drugs, with potential for severe adverse drug reactions. We report the occurrence of adverse events (AEs) during a standardised DR-TB treatment regimen at two outpatient, decentralized, public-sector sites in Johannesburg, South Africa...

Chronic Hepatitis C is a major public health problem. The chronicity of the Hepatitis C can lead to advanced liver disease, cirrhosis and even hepatocellular carcinoma. Chronic hepatitis C is the leading indication of for liver transplantation in the United States. Since the introduction of directly acting antiviral agents (DAAs), there have been there have been dramatic advances in treatment of hepatitis C in terms of tolerability, duration of therapy with significant increases in the rates of sustained virology response (SVR)...

Current antiretrovirals (ARVs) have demonstrated the ability to prolong the life of an HIV infected individual via suppression of the virus and subsequent restoration of immune function. Despite significant advancement, there remains an opportunity for improvement. One ARV that attempts to fill global HIV therapeutic needs by balancing convenience, safety, and efficacy is elvitegravir (EVG). Areas covered: Using MEDLINE/PubMed, a literature search was conducted for published articles on the safety and efficacy of EVG in the treatment of HIV infection...

Co-infection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) often accelerates the course of HCV-associated liver disease. Daclatasvir (DCV) plus asunaprevir (ASV) have been shown to be highly effective for HCV-infected patients with genotype 1b. Three patients co-infected with HIV/HCV genotype 1b were enrolled in this study. Prior to initiation of HCV treatment, the variants associated with L31 and Y93 in the non-structural protein 5A (NS5A) region of the HCV genome were confirmed to be absent using a direct sequencing method...

BACKGROUND: There is a scarcity of data on the distribution of human papillomavirus (HPV) genotypes in the HIV positive population and in invasive cervical cancer (ICC) in Kenya. This may be different from genotypes found in abnormal cytology. Yet, with the advent of preventive HPV vaccines that target HPV 16 and 18, and the nonavalent vaccine targeting 90% of all ICC cases, such HPV genotype distribution data are indispensable for predicting the impact of vaccination and HPV screening on prevention...

OBJECTIVE: To investigate the HIV-1 molecular epidemiology among young people (18 to 25 years old) in Hangzhou. METHODS: Plasma samples from 262 newly diagnosed HIV-1 infected patients were collected between 2009 and 2013 from Hangzhou of Zhejiang province. HIV-1 nucleotide sequences of pol gene regions were amplified using a nested PCR method and sequenced. Phylogenetic and recombination analyses were used to determine the HIV-1 genotypes. RESULTS: Based on all sequences generated, the subtype/circulating recombinant forms (CRF) distribution was as follows: CRF01_AE (68...

CD8(+) T cell recognition of virus-infected cells is characteristically restricted by major histocompatibility complex (MHC) class I, although rare examples of MHC class II restriction have been reported in Cd4-deficient mice and a macaque SIV vaccine trial using a recombinant cytomegalovirus vector. Here, we demonstrate the presence of human leukocyte antigen (HLA) class II-restricted CD8(+) T cell responses with antiviral properties in a small subset of HIV-infected individuals. In these individuals, T cell receptor β (TCRβ) analysis revealed that class II-restricted CD8(+) T cells underwent clonal expansion and mediated killing of HIV-infected cells...

BACKGROUND: Urine biomarkers have helped identify persons at risk for progressing to kidney disease in the setting of HIV infection. We explored factors associated with changes in three urine biomarkers over 10 years among women living with HIV. METHODS: Prospective cohort of 294 HIV-infected women from the multicenter Women's Interagency HIV Study (WIHS). Predictors included HIV viral and immunological parameters, co-morbid conditions and health-related behaviors...

HIV type 1 overcomes the host restriction factor apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3 (APOBEC3) proteins by organizing an E3 ubiquitin ligase complex together with viral infectivity factor (Vif) and a host transcription cofactor core binding factor β (CBFβ ). CBFβ is essential for Vif to counteract APOBEC3 by enabling the recruitment of cullin 5 to the complex and increasing steady-state level of Vif protein, however, the mechanisms by which CBFβ up-regulates Vif protein remains unclear...

BACKGROUND: Co-infection with Mycobacterium tuberculosis remains a leading cause of morbidity and mortality among HIV infected individuals especially in developing countries. Early initiation of cART in these patients when CD4+ T cell count is less than 200cells/mm(3) has reduced disease progression and mortality. However for patients with higher CD4+ T cell counts greater than 350cells/mm(3) evidence is conflicting. In this study we seek to evaluate the effectiveness of cART in reducing mortality among TB-HIV co-infected patients with CD4 + T cells above 350cells/mm(3) at the time of TB diagnosis...
