Assessment of Acceptability of Pre-exposure Prophylaxis for HIV Prevention Among Men Who Sex with Men and Transgender Community in Pakistan.

OBJECTIVE: To assess the level of acceptability of oral pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) and transwomen (TW) in Pakistan. STUDY DESIGN: Cross-sectional study. Place and Duration of the Study: Online study portal from September to November 2021. METHODOLOGY: The study participants were recruited through snowball sampling. Consenting individuals who were >13 years and were identified as MSM or TW were included in the study. Data were analysed using SPSS version 25. Frequencies, percentages and correlation coefficients were computed. RESULTS: A total of 347 participants were recruited. The mean age of all participants was 29.8 ± 6.7 years. Fifty-eight (19.7%) of the participants had chemsex with amphetamine-type stimulants (ATS) at least once in preceding six months of the study, and 58 (19.7%) had a sexually transmitted infection (STI) in preceding six months whereas 10 (3.4%) participants had used drugs via injection. Two hundred and thirty-eight (72%) of the participants were aware of PrEP, 30 (11.7%) had used PrEP in the past, and 3.88% were currently using PrEP. The willingness to use PrEP, free of cost, was shown by 300 participants (86.45%) and by 180 (54.5%), if available at a low cost. CONCLUSION: There was a high prevalence of risk factors posing them at considerable risk of human immunodeficiency virus (HIV). The majority was aware of PrEP for HIV prevention. The willingness to use PrEP was high when PrEP was offered free of cost but dropped down when participants were asked to pay for PrEP. Based on this finding, PrEP should be available free of cost at the community preferred outlets. KEY WORDS: Gay, Men who have sex with men, HIV, Pre-exposure prophylaxis Pakistan, Transwomen, Chemsex, People living with HIV.

Acceptability and feasibility of intra-peer and social media approach for HIV self-testing among men who have sex with men in Karachi: lessons from a pilot study.

OBJECTIVE: To use a peer-to-peer and social media approach to reach out to men who have sex with men (MSM) and to distribute human immunodeficiency virus self-testing kits among them in an urban setting. METHODS: The cross-sectional, pilot study was conducted by a community-based organisation in Karachi from November 2020 to February 2021, and comprised men aged 18 years or above who have sex with men. The subjects were provided one human immunodeficiency virus self-testing kit (HIVST) per person by trained outreach workers. It was an oral fluid-based kit. Data related to demographics, behavioural patterns and human immunodeficiency virus testing detail was collected on a structured questionnaire with some open-ended questions. The analysis of qualitative data was done manually, using content analysis technique in which all common responses were grouped that led to the generation of themes. RESULTS: There were 150 male subjects with mean age 31.5+/-8.7 years. Overall, 62(41.3%) subjects had received up to 15 years of formal education, 94(62.6%) were first-time testers; 139(92.7%) performed the test at home; 11(7.3%) used the kit at the community-based organisation's office. In terms of results, 1(0.7%) participant had a reactive result which was later confirmed as positive for human immunodeficiency virus. Of the total, 145(96.6%) participants found the instructions and the kit easy to use on their own, 83(55.3%) preferred a social media-based approach, and 68(45.3%) preferred the peer-to-peer approach. CONCLUSIONS: The HIVST was found to be acceptable among men who have sex with men, while peer-led and social media approaches seemed to be an effective method of information dissemination.

Acceptability and feasibility of HIV self-testing among transgender people in Larkana, Pakistan: Results from a pilot project.

BACKGROUND: HIV self-testing (HIVST) is an innovative HIV testing approach that effectively reaches those who do not otherwise test, including key populations (KPs). Despite potential benefits, HIVST is not currently implemented in Pakistan. The high risk of HIV among transgender (TGs) persons is among the highest risk group for HIV in Pakistan, yet knowledge of HIV status remains low in this key population group. We conducted a pilot project to assess the acceptability and feasibility of distributing HIVST to TGs in Larkana. METHODS: Eligible participants were 18 years or above and self-identified as transgender ("hijra"). One oral fluid HIVST kit per person was distributed free of cost in the community by trained transgender peer outreach workers (ORW). Participants could request a demonstration of the HIVST procedure before performing self-testing which was provided by the trained ORW. Demographic characteristics of participants were collected. The ORW followed up with phone calls two days later to record if HIVST kits were used, the results, and whether assistance was required. RESULTS: Between November 2020 and February 2021, 150 HIVST kits were distributed to eligible TGs. The average age of participants was 25.5 years (standard deviation: 7.0). Over a third (52, 34.7%) had no formal education, while (16, 10.6%) had attended at least five years of schooling. Over one-third (58, 38.6%) of participants were first-time testers. One hundred and thirty-nine (92.7%) participants reported their results within two days. For the remaining 11 participants, ORWs had to contact them. All participants reported using HIVST kits within three days. A majority (141, 94%) used the kit in their homes, and the remaining nine (6%) used it at the community-based organization's office. Overall, a small proportion (11, 7.3%) of participants requested a demonstration of the test procedure before performing HIVST. Four (2.7%) participants who had performed unsupervised self-tests reported reactive HIVST results; all were linked to treatment within five working days once their HIV result was confirmed. The majority (136, 90.6%) of participants felt that self-testing was easy to perform independently, and 143 (95%) reported that they would recommend HIVST to their peers. CONCLUSION: HIVST is acceptable among TGs and identified by first-time testers as undiagnosed infections. Peer-led distribution appears to be a feasible approach for implementation in this setting. HIVST should be considered for routine implementation and scale up to reduce testing gaps among Pakistan's key population, particularly TGs.

Index testing among HIV-positive patients is feasible and successful in identifying additional HIV infections in Pakistan.

OBJECTIVE: To assess the feasibility of index testing approach to test the parents and siblings of human immunodeficiency virus (HIV)-positive children, and identify HIV-positive individuals. METHODS: The study was conducted at Ratodero, Pakistan. Study participants were enrolled from September 2019 to February 2020. The list of HIV-positive persons was provided by the Sindh AIDS Control Programme. Families of 706 HIV-positive persons were approached and all of them agreed to participate. The first test was performed by trained outreach workers. All those with a reactive first test were transported to the nearest health facility for further testing and confirmation. Mothers and siblings were tested at home while additional visits were carried out to reach the fathers. RESULTS: A total of 1766 persons were tested through HIV index testing. Biological siblings accounted for 81% of the contacts. We were able to test 413/463 (89.2%) mothers, 232/413 (56.2%) fathers and 1121/1392 (80.5%) siblings. Out of these, 7 mothers (1.7%) and 22 siblings (2.0%) were confirmed to be HIV-positive, while no one was found to be positive among the fathers. The overall HIV prevalence was 1.6% (29/1766). All HIV-positive persons were guided for treatment and care. CONCLUSIONS: Results indicate that index-testing approach is feasible in Pakistan to expand HIV testing services through home visits.

Research on health priorities: a regional agenda and its implementation in Jordan and Pakistan.

The Eastern Mediterranean Region (EMR) is facing extraordinary social and health challenges, aggravated by epidemiologic variations, high morbidity and mortality burden (communicable, noncommunicable, injuries), consequences of emergencies (including current COVID-19 pandemic), conflicts and massive migrant population movements. Research for health is essential for generating necessary evidence, which contributes to sustainable development, economic growth and sound health policy-making. Moreover, research for health that addresses national public health priorities is essential for developing required evidence for explanations that contribute towards health improvement and can assist in best utilization of available resources towards issues that maximize the research impact on population health.

Examining unsafe injection practices associated with auto-disable (AD) syringes: a systematic review.

Auto-disable (AD) syringes are specifically designed to prevent syringe reuse. However, the notion that specific AD syringe designs may be unsafe due to reuse concerns related to the syringe's activation point has surfaced. We conducted a systematic review for evidence on the association between AD syringe design and syringe reuse, adverse events following immunization (AEFI), or blood borne virus (BBV) transmission. We found no evidence of an association between AD syringe design and unsafe injection practices including syringe reuse, AEFIs, or BBVs. Authors of three records speculated about the possibility of AD syringe reuse through intentionally defeating the disabling mechanism, and one hinted at the possibility of reuse of larger-than-required syringes, but none reported any actual reuse instance. In contrast to AD syringes, standard disposable syringes continue to be reused; therefore, the global health community should expand the use of AD syringes in both immunization and therapeutic context as an essential strategy for curbing BBV transmission.

Visibility and Analytics Network (VAN) approach to improve immunization supply chain and management performance system in Pakistan.

BACKGROUND: Pakistan has been experiencing several immunization related challenges. The supply chain management information system (MIS) is considered an important component of immunization services as it can improve visibility in key areas such as vaccine shortages or wastage. This study assessed the effectiveness of the Visibility and Analytics Network (VAN) approach in improving vaccine supply and availability of stocks by comparing the situation in intervention and non-intervention districts in Sindh province of Pakistan. METHODS: We utilized a quantitative and qualitative approach to collect data to assess the VAN approach in two districts of Sindh province in Pakistan. The data were collected between August and October 2017. VAN is a systematic monitoring system which measures the performance of vaccine supply chain management based on a set of indicators. We assessed storage facilities of the Expanded Programme on Immunization (EPI) in Sindh and interviewed personnel involved using a pre-tested data collection tool. We also conducted in depth interviews with senior management to assess performance of VAN, adoption mechanism and needs to scale up the VAN approach. RESULTS: We assessed 52 EPI facilities of Sindh province government. In the intervention district 83.3% managers were using MIS data for decision making related to vaccine supplies whereas in the non- intervention district no MIS based data were available. Ninety percent of stores were maintaining a stock registry and 100% supplies matched with requisitions in the intervention district compared to 40% and 35% in the non-intervention district for the same variables. Vaccine wastage was high in the non- intervention district (BCG 46.7% vs 33.9; OPV 13.5% vs 9.5%; pneumococcal 11.4% vs 7.4%). In-depth interview findings suggested that the VAN approach provided data guided monitoring in Pakistan for the first time. The approach also enabled district managers to make timely decisions. CONCLUSION: The VAN approach improves vaccine supply chain management. It should be scaled up and implemented at national or sub national especially in countries struggling with vaccine supply chain management.

Is Pakistan at the cusp of an ART resistance?

Only 10% of HIV positive individuals in Pakistan are receiving anti-retroviral therapy (ART) and the dropout rate from HIV treatment is extremely high. This short report attempts to highlight the risk of ART resistance. Pakistan National AIDS Control Programme's website reports 15,390 HIV positive persons receiving ART out of which 4,697 (30.5%) are people who inject drugs (PWIDs) among whom HIV prevalence is reported to be 38.4%. In the two large provinces of the country (Punjab and Sindh) with more than 90% burden of HIV, ART was initiated in 2,807 patients between April and September 2018, out of these 37% were lost to follow up. Many patients have cited issues related to quality of service at the ART centres as one of the reasons to not revisiting the treatment centres. HIV planners in Pakistan urgently need to make a new strategy and improve not only the quality of services but also increase the number of HIV positive persons receiving ART.

Reuse of syringes for therapeutic injections in Pakistan: rethinking determinants.

BACKGROUND: Frequent reuse of syringes during medical injections is fuelling epidemics of human immunodeficiency virus and hepatitis C virus infections in many low- and middle-income countries including Pakistan. AIMS: To explore specific factors related to syringe reuse during therapeutic injections. METHODS: We randomly surveyed 319 healthcare providers from 2 socioeconomically diverse districts in Pakistan, along with 625 of their patients. RESULTS: Providers see 12-25 patients per day, and provide 7-14 therapeutic injections or intravenous drips. Comparing daily stocks with injections provided, we estimated that 38% of providers (Rawalpindi: 14%, Tando Allah Yar: 44%) likely reuse syringes 2 or 3 times. Rural location and longer duration of practice predict a higher likelihood of reuse. Physicians and non-physicians were equally likely to reuse. Most patients were unaware when a syringe had been reused. CONCLUSIONS: High rate of syringe reuse is driven by high injection demand by patients, to which providers comply. Patients are generally unaware of the harm of injections with syringe reuse or that reuse happens. Our findings suggest that patient focused approaches may help reduce syringe reuse.

Hepatitis C elimination in Pakistan is a distant dream unless government controls the health sector.

The World Health Organisation (WHO) has set an ambitious target to eliminate hepatitis C virus (HCV) by 2030. Pakistan is one of the focused countries because of the high prevalence of HCV. The prices of direct-acting antiviral drugs(DAA)have significantly reduced to between 11-25 dollars for a month's treatment. To achieve the 2030 elimination target, Pakistan has to provide treatment to one million HCV-infected patients every year, beginning from 2018. This short report highlights a key barrier to achieve this target,i.e. the unsafe practices by regulated and unregulated healthcare delivery system comprising trained and untrained healthcare providers who can continue to churn out new patients with their unsafe healthcare practices and increase the possibility of reinfection in those who have been treated. Only the government has the power and authority to regulate and control the healthcare delivery system. Elimination of Hepatitis in Pakistan will remain a distant dream unless the healthcare delivery system is tamed.

Injection practices in 2011-2015: a review using data from the demographic and health surveys (DHS).

BACKGROUND: Reuse of injection devices to give healthcare injections decreased from 39.8 to 5.5% between 2000 and 2010, but trends since 2011 have not been described. We reviewed results of Demographic and Health Surveys (DHS) to describe injection practices worldwide from 2011 to 2015. METHODS: We searched the DHS Internet site for data published on injection practices conducted in countries from 2011 to 2015, extracted information on frequency (number of healthcare injections per person in the last 12 months) and safety (proportion of syringes and needles taken from a new, unopened package). We compared gender groups and WHO regions in terms of frequency and safety. For countries with data available, we compared injection practices 2004-2010 and 2011-2015. RESULTS: Since 2011, 40 of 92 countries (43%) that conducted DHS surveys reported on injection practices. On average, the frequency of injection was 1.64 per person per year (from 3.84 in WHO Eastern Mediterranean region to 1.18 in WHO African region). Among those, 96.1% of injections reportedly used new injection devices (from 90.2% in the WHO Eastern Mediterranean region to 98.8% in the WHO Western Pacific region). On average, women received more injections per year (1.85) than men (1.41). Among 16 (40%) countries with data in 2004-2010 and 2011-2015, 69% improved in terms of safety. The annual number of unsafe injections reduced in 81% of countries. In Pakistan, the number of unsafe injections was the highest and did not decrease between 2006 and 2012. CONCLUSIONS: Injection practices have continued to improve in most countries worldwide, although the Eastern Mediterranean region in particular still faces unsafe practices that are not improving. Further efforts are needed to eliminate unsafe injection practices in health care settings, including through the use of reuse-prevention devices. Despite some limitations, DHS is an easily available method to measure progress over time.

Correlates of Knowledge of HIV Transmission Among Incident Cases of HIV in a Cohort of Injection Drug Users Receiving Harm Reduction Services at Karachi, Pakistan.

BACKGROUND: Knowledge of risk factors for HIV transmission in high-risk population plays a critical role in averting the risk of HIV transmission. In Pakistan, injection drug users (IDUs) constitute the core risk group of HIV prevalence, where the epidemic has transitioned to a "concentrated level." Still nothing is known about the role of knowledge in HIV transmission and HIV sero-conversion among IDUs in Pakistan. METHODS: From 2009 to 2011, a nested case-control study was conducted in a cohort of 636 IDUs receiving harm reduction services in the mega city of Karachi. RESULTS: In multivariable regression analysis, 3 factors, namely HIV does not spread through unprotected sex (adjusted odds ratio [AOR]: 3.1, 95% confidence interval [CI] 1.39-6.90, P value .01), HIV does not transmit by sharing syringes (AOR: 3.5, 95% CI 1.97-6.40, P value <.00), and the risk of HIV cannot be minimized by using new syringe every time (AOR: 2.0, 95% CI 1.16-3.60, P value .01), were significantly associated with the incident cases of HIV. CONCLUSION: The study findings suggest the association between knowledge of HIV transmission and HIV sero-incident cases.

Towards safe injection practices for prevention of hepatitis C transmission in South Asia: Challenges and progress.

AIM: To summarize the available information about injection use and its determinants in the South Asian region. METHODS: We searched published and unpublished literature on injection safety in South Asia published during 1995-2016 using the keywords "injection" "unsafe injection" and "immunization injection" and combined these with each of the countries and/or their respective states or provinces in South Asia. We used a standardized questionnaire to abstract the following data from the articles: the annual number of injections per capita, the proportion of injections administered with a reused syringe or needle, the distribution of injections with respect to prescribers and providers and determinants of injection use. RESULTS: Although information is very limited for certain countries (i.e., Bhutan, Maldives and Sri Lanka), healthcare injection use is very common across South Asia, with cross-country rates ranging from 2.4 to 13.6 injections/person/year. Furthermore, recent studies show that 5% to 50% of these injections are provided with reused syringes, thus creating potential to transmission of blood-borne pathogens. Qualified and unqualified practitioners, especially in the private sector, are the major drivers behind injection use, but patients also prefer injections, especially among the rural, poor or uneducated in certain countries. According to available data, Pakistan and India have recently taken steps towards achieving safe injection. Potential interventions include the introduction of reuse prevention devices, and patient-, community- and patient/community and provider-centered interventions to change population and practitioner behavior. CONCLUSION: Injection use is common in South Asian countries. Multilevel interventions aiming at patients, providers and the healthcare system are needed to reduce injection use and reuse.

Risk Factors for Loss to Follow-Up among People Who Inject Drugs in a Risk Reduction Program at Karachi, Pakistan. A Case-Cohort Study.

INTRODUCTION: Retention of male people who inject drugs (PWIDs) is a major challenge for harm reduction programs that include sterile needle/syringe exchange in resource-limited settings like Pakistan. We assessed the risk factors for loss to follow-up among male PWIDs enrolled in a risk reduction program in Karachi, Pakistan. METHODS: We conducted a prospective cohort study among 636 HIV-uninfected male PWIDs enrolled during March-June 2009 in a harm reduction program for the estimation of incidence rate. At 24 months post-enrollment, clients who had dropped out of the program were defined as lost to follow-up and included as cases for case-cohort study. RESULTS: The median age of the participants was 29 years (interquartile range: 23-36). Active outreach accounted for 76% (483/636) of cohort recruits. Loss to follow-up at 24 months was 25.5% (162/636). In multivariable logistic regression, younger age (AOR: 0.97, 95% CI: 0.92-0.99, p = 0.028), clients from other provinces than Sindh (AOR: 1.49, 95% CI: 1.01-2.22, p = 0.046), having no formal education (AOR: 3.44, 95% CI: 2.35-4.90, p<0.001), a history of incarceration (AOR: 1.68, 95% CI: 1.14-2.46, p<0.008), and being homeless (AOR: 1.47, 95% CI: 1.00-2.19, p<0.049) were associated with loss to follow-up. CONCLUSIONS: Our cohort retained 74.5% of male PWIDs in Karachi for 24 months. Its loss to follow up rate suggested substantial ongoing programmatic challenges. Programmatic enhancements are needed for the highest risk male PWIDs, i.e., younger men, men not from Sindh Province, men who are poorly educated, formerly incarcerated, and/or homeless.
