Metabolic Syndrome in People Living with Antiretroviral Therapy: A Cross-Sectional Investigation from Pune, India

Background: Improved longevity of people living with HIV on highly active antiretroviral therapy and accelerated aging processes are considered contributory to Metabolic Syndrome. Objectives: The current study investigated metabolic syndrome (MetS) in people living with HIV (PLH) who were receiving antiretroviral therapy (ART) under the ongoing National AIDS Control Program. Methods: Clinic attendees(n = 3088) who were on ART for more than 6 months constituted the sampling frame, from which 378 study participants were randomly drawn and included in the analysis following the eligibility check. One hundred and fifty‑nine clinic attendees, initiated on ART in ≤6 months, provided an opportunity to estimate the prevalence of MetS in them. Sixty‑two PLH from this smaller group were enrolled. Results: MetS was found among 19% (73/378; 95% confidence interval [CI] 15.5%–23.7%) PLH who were on ART >6 months compared with 24% (15/62; 95% CI 14.2%–36.7%) in those who were on ART for ≤6 months based on harmonization criteria for the Asian population; the confidence intervals overlapped and apparently observed difference was not statistically significant. Adjusted for age, body mass index (BMI), protease inhibitor (PI)‑based ART regimen, duration of ART, insulin resistance (IR), reported family history of hypertension and residential setting, factors independently associated with MetS were PI containing ART regimen, IR, duration of ART intake and BMI. In the adjusted model, the odds of MetS were three times higher among PLH on PI containing ART regimen (95% CI of adjusted odds ratio; aOR 1.27–8.51) and those having IR (95% CI of aOR 1.48–5.07). The odds of MetS among PLH with BMI ≥23 kg/m2 was 4 (95% CI of aOR 2.08–6.81) times higher than those with lower BMI. Conclusions: MetS in PLH requires the attention of health‑care workers in India. Appropriate screening would help initiate early management.

Expanded Indian National Rotavirus Surveillance Network in the Context of Rotavirus Vaccine Introduction.

Objective: To extend a nation-wide rotavirus surveillance network in India, and to generate geographically representative data on rotaviral disease burden and prevalent strains. Design: Hospital-based surveillance. Setting: A comprehensive multicenter, multi-state hospital based surveillance network was established in a phased manner involving 28 hospital sites across 17 states and two union territories in India. Patients: Cases of acute diarrhea among children below 5 years of age admitted in the participating hospitals. Results: During the 28-month study period between September 2012 and December 2014, 11898 children were enrolled and stool samples from 10207 children admitted with acute diarrhea were tested; 39.6% were positive for rotavirus. Highest positivity was seen in Tanda (60.4%) and Bhubaneswar (60.4%) followed by Midnapore (59.5%). Rotavirus infection was seen more among children aged below 2 years with highest (46.7%) positivity in the age group of 12-23 months. Cooler months of September – February accounted for most of the rotavirus-associated gastroenteritis, with highest prevalence seen during December – February (56.4%). 64% of rotavirus-infected children had severe to very severe disease. G1 P[8] was the predominant rotavirus strain (62.7%) during the surveillance period. Conclusions: The surveillance data highlights the high rotaviral disease burden in India. The network will continue to be a platform for monitoring the impact of the vaccine.

An Outbreak of Cholera Associated with an Unprotected Well in Parbatia, Orissa, Eastern India.

In November 2003, an outbreak (41 cases; attack rate–4.3%; no deaths) of severe diarrhoea was reported from a village in Orissa, eastern India. Thirteen of these cases were hospitalized. A matched case-control study was conducted to identify the possible exposure variables. Since all wells were heavily chlorinated immediately after the outbreak, water samples were not tested. The cases were managed symptomatically. Descriptive epidemiology suggested clustering of cases around one public well. Vibrio cholerae El Tor O1, serotype Ogawa was isolated from four of six rectal swabs. The water from the public well was associated with the outbreak (matched odds ratio: 12; 95% confidence interval 1.2-44.1). On the basis of these conclusions, access to the well was barred immediately, and it was protected. This investigation highlighted the broader use of field epidemiology methods to implement public-health actions guided by epidemiologic data to control a cholera epidemic.
