Discordance of 3rd and 4th generation QuantiFERON-TB Gold assays by pregnancy stages in India.

Background: Pregnancy and HIV affect CD4+ T lymphocytes and impact performance of QuantiFERON-TB Gold (QFT). We compared the results of QFT with QuantiFERON-TB Gold Plus (QFT-Plus), which also measures CD8+ responses to TB antigens, during pregnancy and postpartum.

Methods: We screened 516 pregnant women for TB infection (TBI) with IGRA.

Burden of COVID-19 and case fatality rate in Pune, India: an analysis of the first and second wave of the pandemic.

Objective: To assess trends in case incidence and fatality rate between the first and second waves, we analyzed programmatic COVID-19 data from Pune city, an epicenter of COVID-19 cases in India.

Method: The trends of cases incidence, time-to-death and case fatality rate (CFR) were analyzed. Poisson regression models adjusted for age and gender were used to determine the independent effect of pandemic waves on mortality.

Tuberculosis preventive treatment should be considered for all household contacts of pulmonary tuberculosis patients in India.

The World Health Organization (WHO) recently changed its guidance for tuberculosis (TB) preventive treatment (TPT) recommending TPT for all pulmonary TB (PTB) exposed household contacts (HHC) to prevent incident TB disease (iTBD), regardless of TB infection (TBI) status. However, this recommendation was conditional as the strength of evidence was not strong. We assessed risk factors for iTBD in recently-exposed adult and pediatric Indian HHC, to determine which HHC subgroups might benefit most from TPT.

Assessment of lung function in successfully treated tuberculosis reveals high burden of ventilatory defects and COPD.

Background: Burden, phenotype and risk-factors of lung function defects in successfully treated tuberculosis cases are unclear.

Methods: We performed spirometry with bronchodilators in new drug-sensitive adult (≥18 years) pulmonary tuberculosis cases during the 12 months following successful treatment in India. Airflow obstruction was defined as pre-bronchodilator FEV1/FVC<5th percentile of Global Lung Initiative mixed-ethnicity reference (lower limit of normal [LLN]).

Tuberculosis screening among persons with diabetes mellitus in Pune, India.

Background: Diabetes mellitus (DM) increases tuberculosis (TB) risk, and there is increasing concern over the public health implications of the convergence of these two epidemics. Screening for TB among people with DM is now recommended in India.

Methods: People with DM seeking care at a large public sector tertiary care hospital clinic in Pune, India, were screened for TB from June 2015 to May 2016.

High prevalence of cryptococcal antigenaemia amongst asymptomatic advanced HIV patients in Pune, India.

Background: The World Health Organization recommends routine cryptococcal antigen (CrAg) screening in advanced AIDS patients initiating antiretroviral treatment (ART). India has yet to adopt this strategy as the burden of cryptococcal antigenaemia is unknown.

Methods: A prospective study was conducted in a large public sector ART centre and the inpatient wards of Sassoon Hospital, Pune, India.

Tuberculosis Risk among Medical Trainees, Pune, India.

During 2012-2013, at a public hospital in Pune, India, 26 (3.9%) cases of tuberculosis were reported among 662 medical trainees, representing an estimated incidence of 3,279 cases/100,000 person-years. Three of these infections were isoniazid-resistant, 1 was multidrug-resistant, and 1 occurred in a trainee who had fulminant hepatitis after starting treatment for TB.
