tuberculosis and hiv

A S Sandhya, Brijesh Prajapat
Thrombocytopenia is one of the most common hematological manifestations seen in HIV patients with approximately 40% of the patients developing thrombocytopenia during their course of illness. Opportunistic infection like tuberculosis is a rare but curative cause of thrombocytopenia in these patients. Clinically, it is a challenge to determine the exact cause and decide the treatment of thrombocytopenia in these patients as both infections can lead to significant thrombocytopenia by varied mechanisms. The treatment options are limited by drug antitubercular treatment highly active antiretroviral therapy (ATT and HAART)-induced thrombocytopenia...

Opportunistic infections (OIs) are the most significant complication of human immunodeficiency virus (HIV) infection. The prevalence of OIs differs among various countries in part due to different climates and socio-economic conditions. We, therefore, carried out the retrospective study at the Public Health Clinical Center of Chengdu, Sichuan to comprehensively investigate the prevalence of OIs, predictors of OIs, and risk factors for in-hospital death among HIV-infected patients. Sichuan in West China is characterized by the largest population living with HIV/Acquired immunodeficiency syndrome (AIDS) across China...

We aimed to estimate for the first time the burden of fungal infections in Uruguay. Data on population characteristics and underlying conditions were extracted from the National Statistics Institute, the World Bank, national registries, and published articles. When no data existed, risk populations were used to estimate frequencies extrapolating from the literature. Population structure (inhabitants): total 3,444,006; 73% adults; 35% women younger than 50 years. Size of populations at risk (total cases per year): HIV infected 12,000; acute myeloid leukemia 126; hematopoietic stem cell transplantation 30; solid organ transplants 134; COPD 272,006; asthma in adults 223,431; cystic fibrosis in adults 48; tuberculosis 613; lung cancer 1400...

BACKGROUND: Cough frequency, and its duration, is a lab-free biomarker that can be used in low-resource settings and has been associated with transmission and treatment response. Radiological characteristics associated with increased cough frequency may be important in understanding transmission. The relationship between cough frequency and cavitary lung disease has never been studied. METHODS: We analyzed 41 human immunodeficiency virus-negative adults with culture-confirmed, drug-susceptible pulmonary tuberculosis throughout treatment...

BACKGROUND: Drug resistant Tuberculosis (TB) is considered a global public health threat. Whole-genome sequencing (WGS) is a new technology for tuberculosis (TB) diagnostics and is capable of providing rapid drug resistance profiles and genotypes for epidemiologic surveillance. Therefore, we used WGS to determine genotypic drug resistance profiles and genetic diversity of drug resistant Mycobacterium tuberculosis isolates from Mwanza, North-western Tanzania. METHODS: A cross-sectional study was conducted at the Bugando Medical Center (BMC) from September 2014 to June 2015...

Tuberculosis (TB) remains a serious threat in underdeveloped areas. Mycobacterium tuberculosis curli pili (MTP), a virulence factor, is a potential biomarker for a reliable point of care (POC) test and was evaluated for its ability to react with Immunoglobulin G (IgG) in TB patients. An MTP synthetic peptide in a slot blot assay was used to screen serum/plasma samples (n = 65) in 3 separate cohorts, including 40 TB positive (16 HIV co-infected), 20 TB negative/HIV negative patients and 5 healthy volunteers...

BACKGROUND: Since 2006, the Peruvian National TB program (NTP) recommends voluntary counseling and testing (VCT) for all tuberculosis (TB) patients. Responding to the differential burden of both diseases in Peru, TB is managed in peripheral health facilities while HIV is managed in referral centers. This study aims to determine the coverage of HIV screening among TB patients and the characteristics of persons not screened. METHODS: From March 2010 to December 2011 we enrolled new smear-positive pulmonary TB adults in 34 health facilities in a district in Lima...

Transgender people experience a disproportionate burden of human immunodeficiency virus (HIV) and incarceration. Discrimination, victimization, poverty, and poor mental health drive vulnerability to HIV and related infections, as well as risk of arrest, detention, and incarceration. In this paper, we systematically review published data on HIV, sexually transmitted infections, viral hepatitis, and tuberculosis among incarcerated transgender people; describe potential structural determinants of HIV risk and transmission; identify gaps in the literature; and make recommendations for research and interventions to address this neglected population...

BACKGROUND: Knowledge of tuberculosis (TB) treatment outcomes is substantially needed to assess the performance of national TB controls programs (NTPs). To date, the overall estimates of treatment outcomes have not been determined in Ethiopia. Therefore, this meta-analysis was undertaken to produce pooled estimates of TB treatment outcomes and to analyze the impact of prior anti-TB drug exposure and HIV co-infection. METHODS: Potentially relevant studies were retrieved from PubMed, EMBASE, and MEDLINE online databases...

BACKGROUND: Precise designation of high risk forms of latent Mycobacterium tuberculosis-M.tb infections (LTBI) is impossible. Delineation of high-risk LTBI can, however, allow for chemoprophylaxis and curtail majority cases of active tuberculosis (ATB). There is epidemiological evidence to support the view that LTBI in context of HIV-1 co-infection is high-risk for progression to ATB relative to LTBI among HIV-ve persons. We recently showed that assays of M.tb thymidylate kinase (TMKmt) antigen and host specific IgG can differentiate ATB from LTBI and or no TB (NTB, or healthy controls)...

OBJECTIVE(S): HIV-positive adolescents have low ART-adherence, with consequent increased risks of mortality, morbidity and viral resistance. Despite high rates of violence against children in the Africa region, no known studies have tested impacts on HIV-positive adolescents. We examine associations of ART-adherence with adolescent violence victimisation by caregivers, teachers, peers, community members, and healthcare providers. DESIGN AND METHODS: HIV-positive adolescents were interviewed (n = 1060), and clinic biomarker data collected...
