A modelling group convened by the World Health Organization and UNAIDS has estimated that if efforts are not made to mitigate and overcome interruptions in health services and supplies during the COVID-19 pandemic, a six-month disruption of antiretroviral therapy could lead to more than 500 000 extra deaths from AIDS-related …
South Asia despite decreasing rates of infectious disease, accounts for a significant proportion of their global burden. The sub-continent is also in the midst of rapid economic growth; large scale changes in land use, access to water and sanitation, and agricultural production; environmental degradation; and technological transformation, all against a …
Global tuberculosis incidence has declined marginally over the past decade, and tuberculosis remains out of control in several parts of the world including Africa and Asia. Although tuberculosis control has been effective in some regions of the world, these gains are threatened by the increasing burden of multidrug-resistant (MDR) and …
South Africa has a large burden of rifampicin-resistant tuberculosis (RR-TB), with 18,734 patients diagnosed in 2014. The number of diagnosed patients has increased substantially with the introduction of the Xpert MTB/RIF test, used for tuberculosis (TB) diagnosis for all patients with presumptive TB. Routine aggregate data suggest a large treatment …
People living with a human immunodeficiency virus (HIV) infection have a high risk of tuberculosis and should undergo regular screening. However, they can be difficult to reach because they are stigmatized and discriminated against. Original Source
Cattle were one of the first animals to be cloned. Scientists in China say they have produced cloned cattle with increased resistance to bovine tuberculosis.Twenty calves were born, of which 11 survived for more than three months. Bovine TB is a risk to cattle in many countries, including parts of …
Novel drug regimens are needed for tuberculosis (TB) treatment. New regimens aim to improve on characteristics such as duration, efficacy, and safety profile, but no single regimen is likely to be ideal in all respects. By linking these regimen characteristics to a novel regimen’s ability to reduce TB incidence and …
Poor-quality medicines present a serious public health problem, particularly in emerging economies and developing countries, and may have a significant impact on the national clinical and economic burden. Attention has largely focused on the increasing availability of deliberately falsified drugs, but substandard medicines are also reaching patients because of poor …
India has 23% of the global burden of active tuberculosis (TB) patients and 27% of the world’s “missing” patients, which includes those who may not have received effective TB care and could potentially spread TB to others. The “cascade of care” is a useful model for visualizing deficiencies in case …
Non-fatal outcomes of disease and injury increasingly detract from the ability of the world’s population to live in full health, a trend largely attributable to an epidemiological transition in many countries from causes aff ecting children, to non-communicable diseases (NCDs) more common in adults. For the Global Burden of Diseases, …
A large isoniazid-resistant tuberculosis outbreak centred on London, United Kingdom, has been ongoing since 1995. The aim of this study was to investigate the power and value of whole genome sequencing (WGS) to resolve the transmission network compared to current molecular strain typing approaches, including analysis of intra-host diversity within …
Mycobacterium tuberculosis is recognised as the primary cause of human tuberculosis worldwide. However, substantial evidence suggests that the burden of Mycobacterium bovis, the cause of bovine tuberculosis, might be underestimated in human beings as the cause of zoonotic tuberculosis. In 2013, results from a systematic review and meta-analysis of global …
While modern cephalosporins developed for broad spectrum antibacterial activities have never been pursued for tuberculosis (TB) therapy, we identified first generation cephalosporins having clinically relevant inhibitory concentrations, both alone and in synergistic drug combinations. Common chemical patterns required for activity against Mycobacterium tuberculosis were identified using structure-activity relationships (SAR) studies. …
The researchers analyzed data for a retrospective cohort of patients treated for extensively drug-resistant tuberculosis in 2 provinces in South Africa and compared predictors of treatment outcome in HIV-positive patients who received or had not received antiretroviral drugs with those for HIV-negative patients. Overall, 220 (62.0%) of 355 patients were …
The prison setting presents not only challenges, but also opportunities, for the prevention and treatment of HIV, viral hepatitis, and tuberculosis. We did a comprehensive literature search of data published between 2005 and 2015 to understand the global epidemiology of HIV, hepatitis C virus (HCV), hepatitis B virus (HBV), and …
India has a large and heterogeneous tribal population of approximately 104 million. This accounts for 8.6 per cent of the total population and it is spread over a vast area. Apart from the States of the northeastern region, Madhya Pradesh, Chhattisgarh, Jharkand, Maharashtra, Orissa and Gujarat have large tribal populations. …
Bedaquiline to be introduced in 104 districts across 5 States, at 6 identified tertiary care centres. On the eve of World Tuberculosis Day, Health Minister J.P. Nadda launched Bedaquiline — new drug for Drug Resistant TB — as part of the national programme. The drug will be introduced in 104 …
Bedaquiline, which is a drug for Multi-Drug Resistant TB, is being introduced at six identified tertiary care centres across India. The Union Health Ministry has introduced Bedaquiline into the national tuberculosis (TB) programme. This was among several initiatives Health Minister J P Nadda launched on Monday. Bedaquiline, which is a …
Immunosuppression resulting from HIV infection increases the risk of progression to active tuberculosis (TB) both in individuals newly exposed to Mycobacterium tuberculosis (MTB) and in those with latent infections. We hypothesized that HIV-positive individuals who do not develop TB, despite living in areas where it is hyperendemic, provide a model …
Reasons for the highly variable and often poor protection conferred by the Mycobacterium bovis bacille Calmette-Guerin (BCG) vaccine are multifaceted and poorly understood. The objective of the study was to determine whether early life PCB (polychlorinated biphenyls) and DDE (1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene) exposure reduces 6-month infant BCG vaccine response.
