METHODS: We retrospectively reviewed the case records of patients with positive serology findings for syphilis in University Malaya Medical Center (UMMC) from January 2010 to December 2015. Serological positivity was defined as having a positive rapid plasma reagin (RPR) or Venereal Disease Research Laboratory (VDRL) with a confirmatory positive Treponema pallidum particle agglutination assay (TPPA). Treatment outcomes were divided into two, success or failure. Demographic and clinical characteristics associated with predictors of treatment failure were assessed using statistical package for the social science (SPSS). This study also included a neurosyphilis descriptive sub-study.
RESULTS: There were 637 patients identified with positive syphilis serology, but 258 patients were excluded as they did not meet the inclusion criteria. 379 patients were then taken for the demographic study; 14 patients (3.7%) were treated for neurosyphilis; 170 patients with complete data were included. In all 42/170 (24.7%) failed treatment, 12/170 (7.1%) had reinfection and 116/170 (68.2%) had treatment success. A final number of 158 patients were then taken and analyzed for predictors of treatment failure after excluding the 12 reinfection patients. Only low baseline RPR (<1:16) was found to be significant on multivariate logistic regression analysis (p value: 0.007, 95% CI: 1.42, 9.21).
CONCLUSION: Most of the patients were HIV positive and from the MSM (Men who have sex with Men) population. Low baseline RPR titre is a predictor of treatment failure.
METHODS: A randomly sampled, nationwide biobehavioural health survey was conducted in 8 prisons in Kyrgyzstan among all soon-to-be-released prisoners; women were oversampled. Consented participants underwent computer-assisted, standardized behavioural health assessment surveys and testing for HIV, HCV, HBV, and syphilis. Prevalence and means were computed, and generalized linear modelling was conducted, with all analyses using weights to account for disproportionate sampling by strata.
RESULTS: Among 381 prisoners who underwent consent procedures, 368 (96.6%) were enrolled in the study. Women were significantly older than men (40.6 vs. 36.5; p=0.004). Weighted prevalence (%), with confidence interval (CI), for each infection was high: HCV (49.7%; CI: 44.8-54.6%), syphilis (19.2%; CI: 15.1-23.5%), HIV (10.3%; CI: 6.9-13.8%), and HBV (6.2%; CI: 3.6-8.9%). Among the 31 people with HIV, 46.5% were aware of being HIV-infected. Men, compared to women, were significantly more likely to have injected drugs (38.3% vs.16.0%; p=0.001). Pre-incarceration and within-prison drug injection, primarily of opioids, was 35.4% and 30.8%, respectively. Independent correlates of HIV infection included lifetime drug injection (adjusted odds ratio [AOR]=38.75; p=0.001), mean number of years injecting (AOR=0.93; p=0.018), mean number of days experiencing drug problems (AOR=1.09; p=0.025), increasing duration of imprisonment (AOR=1.08; p=0.02 for each year) and having syphilis (AOR=3.51; p=0.003), while being female (AOR=3.06; p=0.004) and being a recidivist offender (AOR=2.67; p=0.008) were independently correlated with syphilis infection.
CONCLUSION: Drug injection, syphilis co-infection, and exposure to increased risk during incarceration are likely to be important contributors to HIV transmission among prisoners in Kyrgyzstan. Compared to the community, HIV is concentrated 34-fold higher in prisoners. A high proportion of undiagnosed syphilis and HIV infections presents a significant gap in the HIV care continuum. Findings highlight the critical importance of evidence-based responses within prison, including enhanced testing for HIV and sexually transmitted infections, to stem the evolving HIV epidemic in the region.
