Burden of genital warts in Peru: an observational study.

Genital warts (GW) are mucosal or skin lesions caused by sexual transmission of human papillomavirus (HPV). This study estimates the frequency of GW cases in physicians' clinics and physicians' usual practices of GW referral and diagnosis in Peru. Participants in this study were a convenience sample of 100 physicians in five specialties: primary care (17), gynecology (37), urology (10), dermatology (31), and infectious diseases (5). Physicians completed a survey and daily log of all patients aged 18-60 years seen over ten days in their offices located in Peru. The survey recorded GW referral patterns and the daily log recorded patient demographic information and GW diagnosis. Among 12,058 patients, the annual GW prevalence (95% confidence interval [CI]) was 2.28% (2.02-2.56) and cumulative incidence (95% CI) was 1.60% (1.38-1.84). Physicians reported that most GW patients were direct consult (73.5% of male and 67.9% of females) and physicians treated most GW patients themselves (73.4% of males and 76.7% of females). As reported, the most common reasons for referring were 'serious cases requiring more specialized treatment' (73.2% of male and 72.2% of female) and 'lack of resources to treat' (26.8% of male and 27.8% of female). We conclude that GW cases are commonly seen by physicians in Peru.

Feasibility of Chlamydia trachomatis screening and treatment in pregnant women in Lima, Peru: a prospective study in two large urban hospitals.

OBJECTIVES: Chlamydia trachomatis, which is asymptomatic in most women, causes significant adverse effects for pregnant women and neonates. No programmes conduct antenatal screening in Latin America. We determined chlamydia prevalence, feasibility and acceptability of chlamydia screening, and adherence to treatment in pregnant women in two urban public hospitals in Lima, Peru. METHODS: We offered chlamydia screening using self-collected vaginal swabs to pregnant women ≥ 16 years of age during their first antenatal visit. Chlamydia-infected women were contacted within 14 days and asked to bring partners for counselling and directly observed therapy with oral azithromycin. Unaccompanied women received counselling, directly observed therapy, and azithromycin to take to partners. Test of cure was performed ≥ 3 weeks after treatment. RESULTS: We approached 640 women for the study and enrolled 600 (93.8%). Median age was 27.3 years (range 16-47), median lifetime partners 2.3 (range 1-50), and median gestational age 26.1 weeks (range 4-41). Chlamydia prevalence was 10% (95% CI 7.7% to 12.7%). Of 60 infected patients, 59 (98%) were treated with one dose of azithromycin. Fifty-two of 59 (88%) returned for test of cure, all of whom were treated successfully, with 46 (86%) achieving negative test of cure with one dose of azithromycin, and 6 (12%) after retreatment with a second dose. CONCLUSIONS: C. trachomatis screening and treatment in pregnancy was feasible and highly acceptable in two urban hospitals in Peru. Chlamydia prevalence was high. Clinical trials to evaluate efficacy and cost-effectiveness of chlamydia screening, and treatment of pregnant women to prevent adverse pregnancy outcomes in low-resource settings, are warranted.

Rapid Syphilis Tests as Catalysts for Health Systems Strengthening: A Case Study from Peru.

OBJECTIVES: Untreated maternal syphilis leads to adverse pregnancy outcomes. The use of point of care tests (POCT) offers an opportunity to improve screening coverage for syphilis and other aspects of health systems. Our objective is to present the experience of the introduction of POCT for syphilis in Peru and describe how new technology can catalyze health system strengthening. METHODS: The study was implemented from September 2009-November 2010 to assess the feasibility of the use of a POCT for syphilis for screening pregnant women in Lima, Peru. Outcomes measured included access to syphilis screening, treatment coverage, partner treatment, effect on patient flow and service efficiency, acceptability among providers and patients, and sustainability. RESULTS: Before the introduction of POCT, a pregnant woman needed 6 visits to the health center in 27 days before she received her syphilis result. We trained 604 health providers and implemented the POCT for syphilis as the "two for one strategy", offering with one finger stick both syphilis and HIV testing. Implementation of the POCT resulted in testing and treatment on the first visit. Screening and treatment coverages for syphilis improved significantly compared with the previous year. Implementation of POCT has been scaled up nationally since the study ended, and coverages for screening, treatment and partner treatment have remained over 92%. CONCLUSIONS: Implementation of POCT for syphilis proved feasible and acceptable, and led to improvement in several aspects of health services. For the process to be effective we highlight the importance of: (1) engaging the authorities; (2) dissipating tensions between providers and identifying champions; (3) training according to the needs; (4) providing monitoring, supervision, support and recognition; (5) sharing results and discussing actions together; (6) consulting and obtaining feedback from users; and (7) integrating with other services such as with rapid HIV testing.
