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.

Settings: All hospitals managing drug-resistant tuberculosis (DR-TB) according to national guidelines in Pakistan. Objectives: To assess the effect of diabetes mellitus (DM) and factors associated with unfavourable outcomes in DR-TB. Methods: A cross-sectional study based on a retrospective record review of patients enrolled on DR-TB treatment from 2010 to 2014 in Pakistan. DR-TB data reported to Pakistan's National TB Control Programme on a monthly basis were used for the study. Result: Among 5811 patients enrolled on second-line drugs, 8.8% had DM. Overall, 68.9% had favourable outcomes. No association was found between DM and DR-TB treatment outcomes (risk ratio 0.90, 95%CI 0.74–1.05). Unfavourable outcomes were more frequent among DR-TB patients with human immunodeficiency virus (HIV) co-infection (OR 11.58, 95%CI 2.20–60.72), extensively drug-resistant TB patients (OR 5.36, 95%CI 1.00–28.72), patients with exposure to both first-line and second-line anti-tuberculosis drugs (OR 2.45, 95%CI 1.21–4.97) and those with a previous history of treatment in the private sector (OR 1.53, 95%CI 1.16–2.02). Conclusion: Although there were limitations to correctly measuring DM and its management, DM appears not to be a risk factor for unfavourable outcomes in DR-TB patients in our study. DR-TB and HIV co-infection, second-line drug resistance and history of treatment in the private sector were nevertheless more frequently associated with adverse outcomes.

SETTING: This study was conducted at a private tertiary hospital engaged with the TB control programme in the city of Lahore, Pakistan. OBJECTIVE: To assess the healthcare-seeking pathways, different delays and factors associated with delays among the patients who presented in the outpatient department with tuberculous lymphadenitis and pleuritis, the most common manifestations of extrapulmonary TB. DESIGN: This cross-sectional study was conducted prospectively from April 2016 to August 2017. RESULTS: The median age of the 339 patients analysed was 22 years (IQR 17–30); tuberculous lymphadenitis was predominant in females (63%), while pleuritis affected more males (64%). Overall, 62% reported seeking care from healthcare providers before diagnosis, of whom 62% sought care from private facilities, 32% visited facilities >2 times and 8% visited traditional healers. Diagnostic delay was associated with tuberculous lymphadenitis, age 15–44 years, poor socio-economic status and poor TB knowledge. CONCLUSION: There was considerable delay in the management of extrapulmonary TB patients, and the health-system delay was the major contributor, leading to increased patient suffering. Efforts towards minimising health-system delay need to be prioritised for patient screening and diagnosis, with a feasible algorithm that is workable in resource-limited settings.

SETTING: This survey was conducted at 35 sites of 20 cities in 15 districts with low programmatic TB case notifications in the past years in Balochistan. OBJECTIVE: To assess the effectiveness of the systemic community-based screening and diagnosis for early detection of TB; and 2) to describe the characteristics and understand the strengths and weaknesses of the intervention in Balochistan, and sociodemographic factors associated with it. DESIGN: This cross-sectional descriptive study was conducted using a mobile van equipped with a digital X-ray machine with computer-aided detection for TB (CAD4TB) software for screening, followed by confirmatory high sensitivity Xpert® MTB/RIF assay testing. RESULTS: A total of 236 (3.4%) TB cases was detected out of 6,899 screened. About 1,168 (17%) presumptive TB cases were identified and 1,065 (91%) sputum samples were tested on Xpert. Among those diagnosed, 166 (70%) were Mycobacterium tuberculosis -positive and 70 (30%) were with clinical suspicion. Of the sputum samples tested, 87% (923/1065) had a probability score of >70 on CAD4TB. CONCLUSION: Community-based screening with innovative activities, comprising sensitive screening and diagnostic tools, effectively improves TB case detection, which might suffice to reduce the prevalence of TB and break the chain of infection transmission in the at-risk population.

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.

Setting: Three public sector tertiary care hospitals in Quetta, Balochistan, Pakistan, with anecdotal evidence of gaps between the diagnosis and treatment of patients with tuberculosis (TB). Objectives: To assess the proportion of pre-treatment loss to follow-up (LTFU), defined as no documented evidence of treatment initiation or referral in TB registers, among smear-positive pulmonary TB patients diagnosed in 2015, and the associated sociodemographic factors. Design: A retrospective cohort study involving the review of laboratory and TB registers. Results: Of 1110 smear-positive TB patients diagnosed (58% female, median age 40 years, 5% from outside the province or the country), 235 (21.2%) were lost to follow-up before starting treatment. Pre-treatment LTFU was higher among males; in patients residing far away, in rural areas, outside the province or the country; and in those without a mobile phone number. Conclusion: About one fifth of the smear-positive TB patients were lost to follow-up before starting treatment. Strengthening the referral and feedback mechanisms and using information technology to improve the tracing of patients is urgently required. Further qualitative research is needed to understand the reasons for pre-treatment LTFU from the patient's perspective.
