Prevalence and associated risk factors of HIV in prisons in Balochistan, Pakistan: a cross-sectional study.

ABSTRACT: Background: The prevalence of HIV is 0.1% in Pakistan, with epidemicity in high-risk groups. The infection is on verge of transmission from key populations to the general population through people who inject drugs and sexual transmission. Prisoners are vulnerable to infectious diseases like HIV. This study was conducted in four prisons in Balochistan, Pakistan to determine the prevalence of HIV and associated risk factors. Methods: This cross sectional study was conducted from March to June 2018, in the prisons of Balochistan. WHO-approved rapid diagnostic kits were used for determining the prevalence of HIV and structured interviews were conducted for the assessment of risk factors. Results: Out of 2084 screened prisoners, 33 (1.6%) were found to be positive. A subset of 104 interviews was analyzed for risk factors of HIV. Among HIV-infected prisoners 68.8% (OR 4.48; 95% CI 1.41-14.2) had extramarital sex, 43.8% (OR 2.09 95% CI 0.69-6.28) had a homosexual experience, and 50% had a history of needle sharing (OR 43; 95% CI 7.77-237). About 94% (OR 16.42; 95% CI 2.09-129.81) of prisoners had a history of drug addiction of any type while 50% (OR 13; 95% CI 2.82-60.01) of HIV-infected had a history of using injectable drugs. Around 75% of HIV-infected prisoners had spent 1-5 years in prison, and 25% had spent more than 10 years. Conclusion: The high prevalence of HIV in prisons of Balochistan demands that preventive and treatment strategies should be designed and implemented carefully, allowing early diagnosis and treatment initiation to minimize the spread of infection among the prisons and ultimately their onward transmission into the community.

Project description:BACKGROUND:Human Immunodeficiency Virus (HIV), Hepatitis, and Tuberculosis (TB) are three primary communicable infections have the likely potential to cause severe morbidity in prison settings. The prison has the most favorable environment for the transmission of infections. We conducted this survey to determine the prevalence and feasibility of rapid diagnostic tests in an active screening of these infectious diseases in prison. METHODS:This cross-sectional survey conducted in central Jail Gaddani, one of the largest prisons in the Balochistan province of Pakistan. All prisoners, jail staffs, and staff's family members participated. Informed consent obtained from each participant before the screening. Van equipped with digital X-ray linked with Computer-Aided Detection for TB (CAD4TB) software used for testing. Sputum samples tested on Xpert for MTB/RIF assay and blood specimens collected for HIV and hepatitis serology. Diagnosed TB patients enrolled for treatment at Basic Management Unit (BMU), reactive on hepatitis Rapid Diagnostic Tools (RDTs) were referred for further testing and management, while HIV reactive referred to Anti Retro Viral (ARV) center for Anti Retro Viral Treatment (ART). RESULTS:A total of 567 participants offered screening, 63% (356) prisoners, 23% (129) staff's family members, and 14% (82) jail staffs. Among tested 10.3% (58/562) were hepatitis seropositive (Hepatitis-C 41 [7.29%] Hepatitis-B, 16 [2.84%] Hepatitis B&C both, 01 [0.17%]). In reactive participants, 49 were prisoners, 08 were jail staffs, and 01 was the staff's family member. HIV seropositive was 4% (24/566), and all were prisoners. Almost 99% (565/567) screened by digital X-ray, 172 (30%) were with abnormal CAD4TB suggestion (score?>?50), out of them sputum of 26% (148) tested on Xpert, and 2% (03) found Mycobacterium tuberculosis Positive (MTB+). A total of five TB patients were detected; out of two were diagnosed clinically. Co-morbidities observed in 15 patients, (01?TB/HIV co-infected, 12 HIV/HCV, 01 HIV/HBV, and 01 HBV/HCV). CONCLUSION:The high frequency of infectious diseases in prison is alarming. For limiting the transmission of infections among prison and community, immediate steps are needed to be taken for improvement of prisons condition by application of recommended screening protocols at the time of the first entry of prisoners in prisons.

Project description:IntroductionTransgender women may face the highest prevalence of HIV of any population, experiencing a disproportionate burden of disease frequently confirmed in surveys throughout the developing and developed world. However, few studies have been conducted specifically for transgender women in China. This study aimed to measure HIV prevalence and explore risk factors for infection in a diverse sample of Chinese transgender women to help advocate for prevention and care interventions for this population.MethodsFrom July 2018 to May 2019, we adapted a respondent-driven sampling (RDS) approach to recruit a diverse sample of 250 transgender women through chains of peer referrals in two cities of eastern China, Nanjing and Suzhou. Eligible participants (i.e. 18 years of age or older, living in Jiangsu province and assigned male sex at birth but currently self-identified as a gender different from male) completed a self-administered questionnaire on a mobile phone to collect demographic characteristics and risk behaviours and underwent HIV testing.Results and discussionThe survey sample was young (82% under age 35 years), with 28.8% having a university degree, 39.2% reporting work at entertainment venues, 47.6% ever having taken hormones and 6.4% being diagnosed with an STI in the last year. One in five (20.8%) reported having engaged in sex work. HIV prevalence was 14.8% (95% CI 10.6 to 19.8), with 75.6% of those testing HIV positive reporting they were already aware of their serostatus. In multivariate analysis, HIV prevalence was significantly higher among transgender women above the age of 24 years, those who work at entertainment venues, who never have taken hormones, and who had been diagnosed with an STI in the last year.ConclusionsThe prevalence of HIV among transgender women in our study, at 14.8%, is among the highest detected in any population in eastern China. Chinese transgender women may therefore follow the disparity in the burden of HIV noted worldwide. Data support policies to prioritize transgender women for HIV testing outreach, for in-depth research to better understand the specific drivers of infection in this population, and for trans-friendly HIV care and prevention programmes to address their specific needs.

Project description:Type 2 diabetes (T2D) has a reported greater prevalence and poorer treatment outcomes in people living with HIV (PLWH) than comparable HIV-uninfected cohorts. We conducted a cross-sectional study to delineate the factors driving T2D in PLWH in an ethnically diverse cohort, and additionally observed how these have changed over time.We studied a diverse HIV cohort in London to determine the prevalence and risk factors for T2D, and compared them to a cohort studied 10 years previously.Patients were classified as normoglycaemic (fasting glucose <6.0 mmol/l) or dysglycaemic (?6.0 mmol/l). The relative contribution to dysglycaemia of modifiable and fixed factors, including demographics, anthropometrics, comorbidities, immune status, and HIV therapy, were analysed using univariate and logistic regression analyses.T2D prevalence was 15.1% in 2015 with a relative risk of 2.4 compared to the general population. The prevalence compared to 6.8% ten years earlier. The 2015 versus the 2005 cohort was significantly older (median age 49 (42-57) years versus 41 (IQR 35-47), p<0.001), had a higher BMI (27.4 (23.3-29.9) versus 24.9 (22.4-28.0) kg/m2 respectively, p = 0.019) and hypertensive (37.9% versus 19.6 respectively, p<0.001). The strongest predictors of dysglycaemia in the 2015 cohort were hepatic steatosis and hypertension, odds ratios (OR) and 95% confidence intervals (CI) 6.74 (3.48-13.03) and 2.92 (1.66-5.16) respectively, and also HIV-related factors of weight gain following antiretroviral initiation and longer known duration of HIV infection (OR 1.07 (1.04-1.11) and 1.06 (1.02-1.10) respectively).The alarmingly high prevalence of T2D in HIV requires improved screening, targeted to older patients and those with a longer duration of exposure to antiretrovirals. Effective diabetes prevention and management strategies are needed urgently to reduce this risk; such interventions should target both conventional risk factors, such as abdominal obesity, and HIV-specific risk factors such as weight gain following initiation of antiretrovirals.

Project description:OBJECTIVES:Epidemiological studies aimed at stroke and its risk factors can help identify persons at higher risk and therefore promote stroke prevention strategies. We aimed to explore the current prevalence of stroke and its associated risk factors in northeast China. DESIGN:Population based cross sectional study. SETTING:Data were collected using a structured precoded questionnaire designed by the Stroke Screening and Prevention Programme of the National Health and Family Planning Commission of China, between January and March 2016. PARTICIPANTS:4100 permanent residents, aged 40 years or older, who had lived in Dehui City of Jilin Province for more than 6 months volunteered to participate in the survey, with a response rate of 92.2%. For the purpose of the present analysis, 48 subjects were excluded due to missing values, giving a total of 4052 people included in this analysis. MAIN OUTCOME MEASURE:The questionnaire included demographic characteristics, stroke related behavioural factors, personal and family medical history of stroke, physical examination and laboratory testing. RESULTS:The overall prevalence of stroke in Jilin Province was 7.2% (95% CI 6.3% to 8.2%). Of all stroke cases, 91.7% (95% CI 87.4% to 94.6%) were ischaemic stroke and 8.3% (95% CI 5.4% to 12.6%) were haemorrhagic stroke. The prevalence rates of dyslipidaemia, smoking and hypertension were ranked as the top three cerebrovascular risk factors and were 62.1%, 61.8% and 57.3%, respectively. We found that hypertension, dyslipidaemia and lack of exercise were associated with ischaemic stroke. However, only hypertension (OR=4.064, 95%?CI 1.358 to 12.160) was significantly associated with haemorrhagic stroke. CONCLUSIONS:The prevalence of stroke, especially ischaemic stroke, and associated cerebrovascular risk factors among adults aged 40 years or older in northeast China were high. A higher regional prevalence of hypertension, dyslipidaemia and lack of exercise may be responsible.

Project description:BACKGROUND:The association between HIV and cardiovascular disease (CVD) has been reported in several studies. However, there is paucity of information on the prevalence of subclinical disease as well as its associated risk factors in sub-Saharan African population. The aim of this study was to determine the prevalence and associated risk factors of peripheral artery disease (PAD) among virologically suppressed HIV-infected participants in Kwara State, Nigeria. METHODS:This study was conducted between July 2018 and December 2018. A total of 150 HIV-infected participants aged between 20 and 55 years and 50 HIV non-infected age-matched controls were randomly recruited in the study. Sociodemographic, anthropometric and clinical data were collected using a well-structured questionnaire. Ankle brachial index (ABI) was measured, PAD was defined as ABI of < 0.9. Cryopreserved serum was used to evaluate lipid profile parameters. Student's t-test and Chi-square were used to compare continuous and categorical variables. Associations of CVD risk factors and clinical data, and lipid profile with low ABI were assessed using logistic regression analysis. RESULTS:The study participants had a mean age of 43.73 ± 8.74, majority were females (72.7%) with a mean duration on ART of 7.73 ± 3.52 years. Hypertension was present in 15.9%, diabetes 4%, family history of CVD 8.6% and metabolic syndrome 17.3% in the study group. The study participants recorded significantly lower mean values for ABI, HDL-C and significantly higher mean values of TG (P < 0.05) compared to the control group. The prevalence of low ABI (14.6%) was higher in the study group compared to the control group (2%). A significantly negative correlation between ABI and duration on ART (r = - 0.163, P = 0.041) and a positive correlation between viral load and TG were observed in the study group. TC (OR 1.784, P = 0.011), LDL-C (OR 1.824, P = 0.010) and CD4 cell count < 200 cells/mm3 (OR 2.635, P = 0.364) were associated with low ABI in the participants. CONCLUSION:Viral suppression with combined antiretroviral therapy and long term treatment is associated with dyslipidaemia, with increased risk of PAD. Prevalence of PAD in virologically-suppressed individuals does not differ from the controls in the population studied.

Project description:BackgroundLeptospirosis is a zoonotic disease transmitted through the urine of wild and domestic animals, and is responsible for over 50,000 deaths each year. In East Africa, prevalence varies greatly, from as low as 7% in Kenya to 37% in Somalia. Transmission epidemiology also varies around the world, with research in Nicaragua showing that rodents are the most clinically important, while studies in Egypt and Chile suggest that dogs may play a more important role. There are no published studies of leptospirosis in Rwanda.Methods & findingsWe performed a cross-sectional survey of asymptomatic adults recruited from five occupational categories. Serum samples were tested using ELISA and Microscopic Agglutination Test (MAT). We found that 40.1% (151/377) of asymptomatic adults had been exposed to Leptospira spp. Almost 36.3% of positive subjects reported contact with rats (137/377) which represent 90.7% among positive leptospira serology compared with 48.2% of negative subjects (182/377) which represent 80.5% among negative leptospira serology (OR 2.37, CI 1.25-4.49) and 1.7 fold on prevalence ratio and 2.37 of odd ratio. Furthermore, being a crop farmer was significantly associated with leptospirosis (OR 2.06, CI 1.29-3.28). We identified 6 asymptomatic subjects (1.6%) who met criteria for acute infection.ConclusionsThis study demonstrates a high prevalence of leptospiral antibodies infection among asymptomatic adults in rural Rwanda, particularly relative to neighboring countries. Although positive subjects were more likely to report rat contact, we found no independent association between rats and leptospirosis infection. Nonetheless, exposure was high among crop farmers, which is supportive of the hypothesis that rats together with domestic livestock might contribute to the transmission. Further studies are needed to understand infecting Leptospira servers and elucidate the transmission epidemiology in Rwanda and identify means of host transmitters.
