South Africa has one of the highest burdens of TB worldwide, driven by the country's widespread prevalence of HIV, and further complicated by drug resistance. Active case finding within the community, particularly in rural areas where healthcare access is limited, can significantly improve diagnosis and treatment coverage in high-incidence settings. We evaluated the potential health and economic consequences of implementing community-based TB/HIV screening and linkage to care. Using a dynamic model of TB and HIV transmission over a time horizon of 10 years, we compared status quo TB/HIV control to community-based TB/HIV screening at frequencies of once every two years, one year, and six months...

AIM: Safer and shorter antituberculosis treatment (ATT) regimens represent the unmet medical need. PATIENTS & METHODS: The patients were randomly assigned into two arms: the first (n = 137) received once-daily sublingual honey lozenge formulated with botanical immunomodulator Immunoxel and the second (n = 132) received placebo lozenges along with conventional ATT. Immunoxel and placebo arms were demographically similar: 102 versus 106 had drug-susceptible TB; 28 versus 20 multidrug-resistant TB (MDR-TB); 7 versus 7 extensively drug resistant TB (XDR-TB); and 22 versus 20 TB-HIV...

Mycobacterium tuberculosis (Mtb) and the Human Immunodeficiency Virus (HIV) pose a major public health threat. The 2015 World Health Organization (WHO) report estimates that one in three HIV deaths is due to Mtb, the causative agent of Tuberculosis (TB). The lethal synergy between these two pathogens leads to a decline in the immune function of infected individuals as well as a rise in morbidity and mortality rates. The deadly interaction between TB and HIV, along with the heightened emergence of drug resistance, drug-drug interactions, reduced drug efficacy and increased drug toxicity, has made the therapeutic management of co-infected individuals a major challenge...

Although human immunodefiency virus (HIV) coinfection is the most important risk factor for poor antituberculosis (anti-TB) treatment response, its effect on the pharmacokinetics of the first-line drugs in children is understudied. This study examined the pharmacokinetics of the four first-line anti-TB drugs in children with tuberculosis (TB) with and without HIV coinfection. Ghanaian children with TB on isoniazid, rifampin, pyrazinamide and ethambutol for at least 4 weeks had blood samples collected at pre-dose, 1, 2, 4, and 8-hours post-dose...

Tuberculosis (TB) is the most prevalent opportunistic infection among HIV patients, and the leading cause of death among HIV patients worldwide. Simultaneous treatment of both diseases is recommended by current guidelines, but can be challenging due to the potential for drug-drug interactions, overlapping toxicities, difficulty adhering to medications, and an increased risk for immune reconstitution inflammatory syndrome (IRIS). Clinical manifestations of TB can also vary between HIV-infected patients and uninfected patients, which can increase the risk for delayed diagnosis...

BACKGROUND: A delay presentation for human immunodeficiency virus (HIV) patient's care (that is late engagement to HIV care due to delayed HIV testing or delayed linkage for HIV care after the diagnosis of HIV positive) is a critical step in the series of HIV patient care continuum. In Ethiopia, delayed presentation (DP) for HIV care among vulnerable groups such as tuberculosis (Tb) /HIV co-infected patients has not been assessed. We aimed to assess the prevalence of and factors associated with DP (CD4 < 200 cells/μl at first visit) among Tb/HIV co-infected patients in southwest Ethiopia...

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...

With anti-retroviral treatment (ART) scale-up set to continue over the next few years it is of key importance that manufacturers and planners in low- and middle-income countries (LMICs) hardest hit by the HIV/AIDS pandemic are able to anticipate and respond to future changes to treatment regimens, generics pipeline and demand, in order to secure continued access to all ARV medicines required. We did a forecast analysis, using secondary WHO and UNAIDS data sources, to estimate the number of people living with HIV (PLHIV) and the market share and demand for a range of new and existing ARV drugs in LMICs up to 2025...
