- Abstract
Background: The Revised National TB Control Program bases diagnosis of tuberculosis (TB) on sputum smear examination and response to a course of antibiotics, whereas World Health Organization recommends early chest radiography [chest x-ray (CXR)] for HIV-infected symptomatic patients. We evaluated the utility of initial CXR in the diagnostic algorithm for symptomatic HIV-infected patients with negative sputum smears., Methods: HIV-infected ambulatory patients with cough or fever of ≥2 weeks and 3 sputum smears negative for acid-fast bacilli were enrolled in Chennai and Pune, India, between 2007 and 2009. After a CXR and 2 sputum cultures, a course of broad-spectrum antibiotics was given and patients were reviewed after 14 days. Sensitivity, specificity, positive and negative predictive values of symptoms, CXR, and various combinations for diagnosing pulmonary tuberculosis (PTB) were determined, using sputum culture as gold standard., Results: Five hundred four patients (330 males; mean age: 35 years; median CD4: 175 cells per cubic millimeter) were enrolled. CXR had a sensitivity and specificity of 72% and 57%, respectively, with positive predictive value (PPV) of 21% and negative predictive value (NPV) of 93% to diagnose PTB. TB culture was positive in 49 of 235 patients (21%) with an abnormal initial CXR and 19 of 269 patients (7%) with a normal CXR (P < 0.001). Sensitivity and specificity of cough ≥2 weeks for predicting PTB was 97% and 6%, with PPV and NPV of 14% and 94%, respectively., Conclusions: Although moderately sensitive, basing a diagnosis of TB on initial CXR leads to overdiagnosis. An absence of weight loss had a high NPV, whereas none of the combinations had a good PPV. A rapid and accurate diagnostic test is required for HIV-infected chest symptomatic.

- Abstract
Objective: A recent report suggesting declining HIV transmission rates in southern India has been based on HIV seroprevalence data to estimate HIV incidence. We analyzed HIV incidence rates among 3 cohorts (male, female non-sex worker, female sex worker [FSW]) presenting to sexually transmitted infection (STI) clinics in Pune, India over 10 years., Methods: Between 1993 and 2002, consenting HIV-uninfected individuals were enrolled in a prospective study of the risks for HIV seroconversion. Standardized HIV incidence estimates were calculated separately for the 3 cohorts., Results: HIV acquisition risk declined by more than 70% for FSWs (P = 0.02) and men (P < 0.001) attending the STI clinics. There was no significant reduction in HIV incidence among women attending STI clinics (P = 0.74). The decline in HIVacquisition risk among male patients with STIs was associated with an increase in reported condom use with recent FSW contact and a decrease in genital ulcer disease., Conclusions: We report the first direct evidence for a decline in HIV incidence rates in FSWs and male patients with STIs over time. The lack of change in HIV infection risk among non-sex worker women highlights the need for additional targeted HIV prevention interventions.

- Abstract
Objectives: To determine HIV/sexually transmitted infection (STI) prevalence, trends, and risk behaviors of men who have sex with men (MSM) and compare these with those of non-MSM attending STI clinics in Pune, India over a 10-year period., Design: Cross-sectional., Methods: From 1993 through 2002, men attending 3 STI clinics in Pune underwent HIV/STI screening. Demographic, risk behavior, clinical, and laboratory data were collected using standardized questionnaires and laboratory procedures., Results: Of 10,785 men screened, 708 (6.6%) were MSM. Among these 708 MSM, 189 (31.7%) had 10 or more lifetime partners, 253 (35.7%) were married, 163 (23.1%) had sex with a hijra (eunuch), and 87 (13.3%) had exchanged money for sex. A total of 134 (18.9%) were HIV-positive, 149 (21.5%) had genital ulcer disease (GUD), 37 (5.8%) had syphilis, and 29 (4.3%) had gonorrhea (GC). Over the decade, neither HIV nor GC prevalence changed among MSM (P = 0.7), but syphilis and GUD decreased significantly (P < 0.0001). Compared with non-MSM, MSM were more likely to initiate sexual activity at age <16 years, to have >10 lifetime partners, to have sex with a hijra, and to use condoms regularly, but they did not differ significantly in HIV prevalence and had a lower prevalence of GC, GUD, and syphilis. Independent factors associated with HIV among MSM were employment (adjusted odds ratio [AOR] = 3.08; P = 0.02), history of GUD (AOR = 1.86; P = 0.003), and syphilis (AOR = 2.09; P = 0.05)., Conclusions: Same-sex and high-risk sexual behaviors are prevalent among men attending STI clinics in India. Although syphilis and GUD rates decreased, HIV prevalence remained high during the decade, highlighting the importance of additional targeted efforts to reduce HIV risk among all men, including MSM, in India.
