Incident HIV infection among men attending STD clinics in Pune, India: pathways to disparity and interventions to enhance equity

Systematic disparities in rates of HIV incidence by socioeconomic status were assessed among men attending three sexually transmitted disease (STD) clinics in Pune, India, to identify key policy-intervention points to increase health equity. Measures of socioeconomic status included level of education, family income, and occupation. From 1993 to 2000, 2,260 HIV-uninfected men who consented to participate in the study were followed on a quarterly basis. Proportional hazards regression analysis of incident HIV infection identified a statistically significant interaction between level of education and genital ulcer disease. Compared to the lowest-risk men without genital ulcer disease who completed high school, the relative risk (RR) for acquisition of HIV was 7.02 (p < 0.001) for illiterate men with genital ulcer disease, 3.62 (p < 0.001) for men with some education and genital ulcer disease, and 3.02 (p < 0.001) for men who completed high school and had genital ulcer disease. For men with no genital ulcer disease and those with no education RR was 1.09 (p = 0.84), and for men with primary/middle school it was 1.70 (p = 0.03). The study provides evidence that by enhancing access to treatment and interventions that include counselling, education, and provision of condoms for prevention of STDs, especially genital ulcer disease, among disadvantaged men, the disparity in rates of HIV incidence could be lessened considerably. Nevertheless, given the same level of knowledge on AIDS, the same level of risk behaviour, and the same level of biological co-factors, the most disadvantaged men still have higher rates of HIV incidence.     

Male circumcision and risk of HIV-1 and other sexually transmitted infections in India

Circumcised men have a lower risk of HIV-1 infection than uncircumcised men. Laboratory findings suggest that the foreskin is enriched with HIV-1 target cells. However, some data suggest that circumcision could simply be a marker for low-risk behaviours. In a prospective study of 2298 HIV-uninfected men attending sexually transmitted infection clinics in India, we noted that circumcision was strongly protective against HIV-1 infection (adjusted relative risk 0.15; 95% CI 0.04-0.62; p=0.0089); however, we noted no protective effect against herpes simplex virus type 2, syphilis, or gonorrhoea. The specificity of this relation suggests a biological rather than behavioural explanation for the protective effect of male circumcision against HIV-1.     

Correlates and trend of HIV prevalence among female sex workers attending sexually transmitted disease clinics in Pune, India (1993-2002)

In India, substantial efforts have been made to increase awareness about HIV/AIDS among female sex workers (FSWs). We assessed the impact of awareness regarding safe sex in a cohort of FSWs by studying trends in HIV prevalence, sexually transmitted diseases (STDs), and risk behaviors measured from 1993 to 2002 in Pune, India. A total of 1359 FSWs attending 3 STD clinics were screened for HIV infection, and data on demographics, sexual behaviors, and past and current STDs were obtained. The overall HIV prevalence among FSWs was 54%. Not being married (adjusted odds ratio [AOR] = 1.74, 95% confidence interval [CI]: 1.17 to 2.59), being widowed (AOR = 2.10, 95% CI: 1.16 to 3.80), inconsistent condom use (AOR = 1.60, 95% CI: 1.02 to 2.50), clinical presence of genital ulcer disease (GUD; AOR = 1.66, 95% CI: 1.07 to 2.56), and genital warts (AOR = 4.70, 95% CI: 1.57 to 14.08) were independently associated with HIV infection among FSWs. The prevalence of HIV remained stable over 10 years (46% in 1993 and 50% in 2002; P = 0.80). The prevalence of GUD decreased over time (P < 0.001), whereas that of observed genital discharge remained stable. Reported consistent condom use as well as the proportion of FSWs who refused sexual contact without condoms increased over time (P < 0.001). These data collectively suggest that safe sex interventions have had a positive impact on FSWs in Pune, India.     

High rates of syphilis among STI patients are contributing to the spread of HIV-1 in India

BACKGROUND: Recent syphilis outbreaks have raised concern regarding the potential enhancement of HIV transmission. The incidence of syphilis and its association with HIV-1 infection rates among a cohort of sexually transmitted infection (STI) clinic attendees was investigated. METHODS: 2732 HIV-1 seronegative patients attending three STI and one gynaecology clinic, were enrolled from 1993-2000 in an ongoing prospective cohort study of acute HIV-1 infection in Pune, India. At screening and quarterly follow up visits, participants underwent HIV-1 risk reduction counselling, risk behaviour assessment and HIV/STI screening that included testing for serological evidence of syphilis by RPR with TPHA confirmation. Patients with genital ulcers were screened with dark field microscopy. RESULTS: Among 2324 participants who were HIV-1 and RPR seronegative at baseline, 172 participants were found to have clinical or laboratory evidence of syphilis during follow up (5.4 per 100 person years, 95% CI 4.8 to 6.5 per 100 person years). Independent predictors of syphilis acquisition based on a Cox proportional hazards model included age less than 20 years, lack of formal education, earlier calendar year of follow up, and recent HIV-1 infection. Based on a median follow up time of 11 months, the incidence of HIV-1 was 5.8 per 100 person years (95% CI 5.0 to 6.6 per 100 person years). Using a Cox proportional hazards model to adjust for known HIV risk factors, the adjusted hazard ratio of HIV-1 infection associated with incident syphilis was 4.44 (95% CI 2.96 to 6.65; p<0.001). CONCLUSIONS: A high incidence rate of syphilis was observed among STI clinic attendees. The elevated risk of HIV-1 infection that was observed among participants with incident syphilis supports the hypothesis that syphilis enhances the sexual transmission of HIV-1 and highlights the importance of early diagnosis and treatment of syphilis.     

The reliability and validity of the Modified Condom Outcome Expectancy Scale (MCOES) among an international sample of HIV-negative partners of people living with HIV/AIDS

Safer sexual behaviour is vital in curbing the HlV epidemic in many developing countries where the epidemic is primarily transmitted through heterosexual sex. Reliable and valid assessment of factors related to HIV risk behaviours are important in testing behavioural theories as well as informing effective AIDS prevention programmes. The current study tests the reliability and validity of a modified version of the Condom Outcome Expectancy Scale (COES) among a sample of HI'-negative sexual partners (n = 100) of HIV-infected individuals in Pune, India, Chang Mai,Thailand and Kampala, Uganda. Internal consistency reliability was measured using Cronbach's alpha coefficient, which had a value of 0.80 for the entire sample, with site-specific values of. 0.78 for India; 0.75 for Thailand; and 0.79 for Uganda. Test-retest reliability was conducted to test the scale's stability over time with 60% of the sample, resulting in a Cronbach's alpha coefficient of 0.70. The scale's structure was explored by analyzing response scores on the items using principal components analysis, which yielded a two-factor solution. The study indicates the utility of a modified version of the widely tested COES across international settings. Such research is necessary in understanding intervention targets across international settings.     

Effect of α-thalassemia on sickle-cell anemia linked to the Arab-Indian haplotype in India

Two population groups from Western India with a high prevalence of the β^s gene, one tribal (Valsad) and the other nontribal (Nagpur), were studied. The β^s gene frequency in both populations was similar (0.22 vs. 0.23), but not the clinical expression of sickle-cell anemia (SS): the sickle homozygotes in the tribal group appeared to have a mild clinical course, whereas the majority in the nontribal group exhibited a more severe clinical phenotype. Both tribal and nontribal SS patients had a similarly high mean hemoglobin (Hb)F expression (18.5% vs. 15.5%) and a high number of F cells (72.3% vs. 66.6%). DNA analysis of the β-globin gene cluster region revealed that in these two populations, this portion of DNA was identical with and corresponded to the typical Arab-Indian haplotype. Nevertheless, in heterozygotes, the mean β^s expression was lower (27.9%) in the tribal as compared to the nontribal group (35.5%). The major epistatic factor distinguishing the milder presentation in tribals vs. a more severe manifestation in nontribals was the very high frequency (0.97) of the α-thalassemia gene in the former as compared to the latter (0.24). We conclude that the phenotypic expression of sickle-cell anemia, linked to the Arab-India haplotype and expressing similar levels of HbF and F cells, is not uniformly mild in India and that α-thalassemia is a powerful and additional epistatic factor in the Indian subcontinent.

Cerebral thrombosis in childhood nephrosis

Sinovenous thrombosis is an uncommon but serious complication associated with nephrotic syndrome in children. We describe a 9-year-old Caucasian boy who presented with dehydration, vague neurological symptoms and seizures. A diagnosis of nephrotic syndrome was made during the course of hospitalization. The serum antithrombin III level was decreased and brain imaging showed cerebral sinovenous thrombosis. Anticoagulant therapy with heparin was commenced and the patient made a slow but gradual clinical, as well as radiological recovery. We describe this case and review available literature to highlight the importance of suspecting and recognizing this potentially life threatening complication and initiating early treatment.
