Prisoners co-infected with tuberculosis and HIV: a systematic review.
INTRODUCTION: Almost from the beginning of the HIV epidemic in 1981, an association with tuberculosis (TB) was recognized. This association between HIV and TB co-infection has been particularly evident amongst prisoners. However, despite this, few studies of TB in prisons have stratified results by HIV status. Given the high prevalence of HIV-positive persons and TB-infected persons in prisons and the documented risk of TB in those infected with HIV, it is of interest to determine how co-infection varies amongst prison populations worldwide. For this reason we have undertaken a systematic review of studies of co-infected prisoners to determine the incidence and/or prevalence of HIV/TB co-infection in prisons, as well as outcomes in this group, measured as treatment success or death. METHODS: A literature search was undertaken using the online databases PubMed, Embase, IBSS, Scopus, Web of Science, Global Health and CINAHL Plus. No restrictions were set on language or publication date for article retrieval, with articles included if indexed up to 18 October 2015. A total of 1975 non-duplicate papers were identified. For treatment and outcome data all eligible papers were appraised for inclusion; for incidence/prevalence estimates papers published prior to 2000 were excluded from full text review. After full text appraisal, 46 papers were selected for inclusion in the review, 41 for incidence/prevalence estimates and nine for outcomes data, with four papers providing evidence for both outcomes and prevalence/incidence. RESULTS: Very few studies estimated the incidence of TB in HIV positive prisoners, with most simply reporting prevalence of co-infection. Co-infection is rarely explicitly measured, with studies simply reporting HIV status in prisoners with TB, or a cross-sectional survey of TB prevalence amongst prisoners with HIV. Estimates of co-infection prevalence ranged from 2.4 to 73.1% and relative risks for one, given the other, ranged from 2.0 to 10.75, although some studies reported no significant association between HIV and TB. Few studies provided a comparison with the risk of co-infection in the general population. CONCLUSIONS: Prisoners infected with HIV are at high risk of developing TB. However, the magnitude of risk varies between different prisons and countries. There is little evidence on treatment outcomes in co-infected prisoners, and the existing evidence is conflicting in regards to HIV status influence on prisoner treatment outcomes.PROSPERO Number: CRD42016034068
High tuberculosis prevalence in a South African prison : the need for routine tuberculosis screening.
CAPRISA, 2014.Background: Tuberculosis is a major health concern in prisons, particularly where HIV prevalence is high. Our objective was to determine the undiagnosed pulmonary tuberculosis (‘‘undiagnosed tuberculosis’’) prevalence in a representative sample of prisoners in a South African prison. In addition we investigated risk factors for undiagnosed tuberculosis, to explore if screening strategies could be targeted to high risk groups, and, the performance of screening tools for tuberculosis.
Methods and Findings: In this cross-sectional survey, male prisoners were screened for tuberculosis using symptoms, chest radiograph (CXR) and two spot sputum specimens for microscopy and culture. Anonymised HIV antibody testing was performed on urine specimens. The sensitivity, specificity and predictive values of symptoms and investigations were calculated, using Mycobacterium tuberculosis isolated on sputum culture as the gold standard. From September 2009 to October 2010, 1046 male prisoners were offered enrolment to the study. A total of 981 (93.8%) consented (median age was
32 years; interquartile range [IQR] 27–37 years) and were screened for tuberculosis. Among 968 not taking tuberculosis treatment and with sputum culture results, 34 (3.5%; 95% confidence interval [CI] 2.4–4.9%) were culture positive for Mycobacterium tuberculosis. HIV prevalence was 25.3% (242/957; 95% CI 22.6–28.2%). Positive HIV status (adjusted odds ratio [aOR] 2.0; 95% CI 1.0–4.2) and being an ex-smoker (aOR 2.6; 95% CI 1.2–5.9) were independently associated with undiagnosed tuberculosis. Compared to the gold standard of positive sputum culture, cough of any duration had a sensitivity of 35.3% and specificity of 79.6%. CXR was the most sensitive single screening modality (sensitivity 70.6%,
specificity 92.2%). Adding CXR to cough of any duration gave a tool with sensitivity of 79.4% and specificity of 73.8%.
Conclusions: Undiagnosed tuberculosis and HIV prevalence was high in this prison, justifying routine screening for tuberculosis at entry into the prison, and intensified case finding among existing prisoners
Substance Use During Imprisonment in Low- and Middle-Income Countries
Substance use disorders are among the most common health problems of people involved in the criminal justice system. Scaling up addiction services in prisons is a global public health and human rights challenge especially in poorly resourced countries. The aim of the present study was to systematically review the prevalence of substance use in prison populations in low- and middle-income countries (LMIC). We searched for studies reporting prevalence rates of nicotine, alcohol, illicit drug and injection drug use during imprisonment in unselected samples of imprisoned people in LMIC. Data were meta-analyzed and sources of heterogeneity examined by meta-regression. The prevalence of nicotine use during imprisonment ranged from 5% to 87% with a random-effects pooled estimate of 56% (95% CI: 45, 66) with significant geographical heterogeneity. Alcohol use varied from 1% to 76%. The pooled prevalence was 16% (95% CI: 9, 25). A quarter of the people who are imprisoned (25%, 95% CI: 17, 33; range: 0, 78) used illicit drugs during imprisonment. The prevalence of injection drug use varied from 0% to 26% with a pooled estimate of 1.6% (95% CI: 0.8, 3.0). Secondary analyses investigated lifetime substance use. The high prevalence of smoking in prison suggests that policies around smoking need careful review. Furthermore, the findings underscore the importance of timely, scalable and available treatments for alcohol and illegal drugs in people involved with the criminal justice system
