Impact of COVID-19 Pandemic on HIV Testing Uptake Among Key Populations Enrolled in Targeted Intervention Program in Maharashtra, India.

The COVID-19 pandemic posed unprecedented challenges to HIV services globally. We evaluated the impact of the COVID-19 pandemic on the uptake of HIV testing in the Targeted Intervention (TI) program in Maharashtra-a high HIV burden state in India. Annual HIV testing was sustained during the pandemic year (2020-2021), at levels similar to the pre-pandemic year (2019-2020), among Female Sex Workers (FSW), Men having Sex with Men (MSM), Transgender (TG), and Truckers; but not among Migrants and Intravenous Drug Users (IDU). There was an acute decline during the lockdown across all typologies. Sharp recovery was seen among FSW, MSM, and TG during the early months of the un-lockdown. The community-based screening (CBS) approach primarily contributed to this recovery. Among migrants and truckers, recovery was delayed. There was an overall reduction of 58% in annual HIV-positive registrations. The community-based networks, participatory structures, and processes of HIV programs played an essential role in reaching the community during the pandemic.

Mapping HIV risk trajectories from adolescence to young adulthood: a life-course study among unmarried urban Indian youth.

The study explores trajectories of HIV risks from adolescence to adulthood among unmarried, educated (12+ years of formal education), 20-29 year old youth. Retrospective time event data (n=517) was used to build HIV risk trajectories (age 10 onwards), employing group-based trajectory technique and multinomial logistic regression in SAS v9.4. Among men (n=271), 10% had "Declining risk - high to low", and 15% had "consistent high risk". Among women (n=246), 11% had "late-rising risk", and 15% had "consistent high risk". Among women, childhood experience of sexual abuse, having self-income, father education until 12th standard, frequent alcohol use predicted higher risk trajectories. Among men, it was an early sexual debut, alcohol dependency in parent/s, non-heterosexual orientation, early sexual debut, and frequent alcohol use. The HIV risk behaviors of unmarried Indian youth are diverse. A subsection engages in high-risk behaviors that change over time and have linkages to developmental factors.

The use of emergency contraceptive pills in India: A meta-analysis.

BACKGROUND: Unplanned pregnancies are a major public health concern. In India, 33% of an estimated 48.1 million pregnancies end in induced abortions. Emergency contraceptive pills (ECPs) can prevent pregnancy after sexual intercourse, have been part of India's family planning program since 2002-2003 and are available as over-the-counter drugs. While there are concerns about the overuse of ECPs, the pattern of use of ECPs in India is unknown. OBJECTIVES: The objective is to determine the proportion of women who have ever used ECPs and repeatedly used ECPs and also to assess the reasons for use and nonuse of EC pills along with factors associated with the use. METHODS: A systematic review of ECP use in India was conducted by electronically searching three databases-PubMed, Popline, and Google Scholar. All studies were published between 2001 and 2017, and the electronic search was last conducted in July 2018. The proportion of use was calculated using meta-analysis, and the other factors were assessed by narratively synthesizing the findings. Thirty-three articles met the inclusion criteria. RESULTS: The pooled proportion of women who ever used ECPs was 6% (95% confidence interval, 0.03-0.10). The proportion of repeat use ranged from 12% to 69%. Five studies reported reasons for not using ECPs, and the most common reasons were religious/cultural beliefs followed by fear of side effects and inadequate knowledge. Studies to understand sociodemographic and other factors affecting the use of ECPs in India are lacking. There are significant concerns about the quality of the studies. The definition of repeat use of ECPs is inconsistent across papers. Furthermore, judgmental attitudes of health-care providers were apparent in some papers. CONCLUSION: The review highlights important research and program gaps.

Increasing sero-discordancy among young HIV infected pregnant women from India: a likely pointer of changing transmission dynamics.

The flat-lining of HIV incidence in India has raised concerns about the presence of emerging risk groups. As HIV prevalence among pregnant women is reflective of the situation in general population, its closer scrutiny provides valuable insights about the evolving epidemic. The present study assesses temporal trends of sero-discordance (where woman is HIV infected and husband is uninfected), among pregnant women living with HIV (pWLHIV) from India. Data of program for prevention of parent to child transmission of HIV was analyzed. Statistical analysis was done using Cochrane-Armitage trend test and logistic regression. Of the 1209 currently married pWLHIV, 302 (25%) were sero-discordant. The proportion increased from 16% in 2007 to 36% in 2016-17 (p = 0.000). The likelihood of sero-discordance was higher for women aged 18-20 (OR: 2.68, CI: 1.30-5.83) and 21-23 (OR: 1.98, CI: 1.01-4.15) years compared to 36-40 years; and for primi-parous women (OR: 1.84, CI: 1.31-2.58) compared to women pregnant for second/third time. The findings are indicative of changing HIV transmission dynamics. Steeper rise in sero-discordance in younger women implies an increasing risk of HIV in unmarried women population. A better understanding of HIV specific vulnerabilities of young women, married and unmarried, is warranted.

Pattern of linkage and retention in HIV care continuum among patients attending referral HIV care clinic in private sector in India.

Continued engagement throughout the HIV care continuum, from HIV diagnosis through retention on antiretroviral therapy (ART), is crucial for enhancing impact of HIV care programs. We assessed linkage and retention in HIV care among people living with HIV (PLHIV) enrolled at a private HIV care clinic in Pune, India. Of 1220 patients, 28% delayed linkage after HIV diagnosis with a median delay of 24 months (IQR = 8-43). Younger people, women, low socioeconomic status, and those diagnosed at facilities other than the study clinic were more likely to delay linkage. Those with advanced HIV disease at diagnosis and testing for HIV due to HIV-related illness were linked to care immediately. Of a total of 629 patients eligible for ART at first CD4 count, 68% initiated ART within 3 months. Among those not eligible for ART, only 46% of patients sought subsequent CD4 count in time. Multivariate logistic regression analysis revealed that patients with initial CD4 count of 350-500 cells/cu mm (OR: 2, 95% CI: 1.1-3.5) and >500 cells/cu mm (OR: 2.1, 95% CI: 1.2-3.7) were less likely to do subsequent CD4 test on time as compared to those with CD4 < 50 cells/cu mm. Among patients not eligible for ART, those having >12 years of education (OR: 0.4, 95% CI: 0.2-0.9) were more likely to have timely uptake of subsequent CD4 count. Among ART eligible patients, being an unskilled laborer (OR: 2.2, 95% CI: 1.1-4.2) predicted lower uptake. The study highlights a long delay from HIV diagnosis to linkage and further attrition during pre-ART and ART phases. It identifies need for newer approaches aimed at timely linkage and continued retention for patients with low education, unskilled laborers, and importantly, asymptomatic patients.

Systematic review of public health research on prevention of mother-to-child transmission of HIV in India with focus on provision and utilization of cascade of PMTCT services.

BACKGROUND: In spite of effective strategies to eliminate mother-to-child-transmission of HIV, the implementation of such strategies remains a major challenge in developing countries. In India, programs for the prevention of mother-to-child transmission (PMTCT) have been scaled up widely since 2005. However, these programs reach only a small percentage of pregnant women, and their overall effectiveness is low. Evidence-based program planning and implementation could significantly improve their effectiveness. This study sought to systematically retrieve, thematically categorize and review published research on PMTCT of HIV in India, focusing on research related to the provision and/or utilization of the cascade of services provided in a PMTCT program, in order to direct further research to enhance program implementation and effectiveness. METHODS: A systematic search using MEDLINE, US National Library of Medicine Gateway system (PubMed) and ISI Web of Knowledge resulted in 1,944 abstracts, of which 167 met our inclusion criteria. RESULTS: A huge share of the empirical literature on PMTCT in India (N = 134) deals with epidemiological studies (N = 60). The 46 papers related to utilization/provision of the cascade of PMTCT services were mostly from the four high HIV prevalence states in southern India and from the public sector. Studies on experiences of implementing a PMTCT program (N = 20) show high rates of drop out of women in the cascade particularly prior to receiving ARV. Studies on individual components of the cascade (N = 26) show that HIV counseling and testing is acceptable and feasible. Literature on other components of the cascade - such as pregnant women's access to ANC care, HIV infected women's immunological assessment using CD4 testing, repeat HIV testing among pregnant women, early infant diagnosis and factors related to linking HIV infected women and children to postnatal care - is lacking. CONCLUSIONS: While the scale of the Indian PMTCT program is large, comprehensive understanding of the context-driven factors affecting its efficiency is lacking. Systematic and more focused public health research output is needed on the issues related to reduction of drop outs of women in the cascade, role of PMTCT programs in improving maternal and child health indicators and role of private sector in delivering PMTCT services.

Understanding Emergent Dynamism of Covid-19 Pandemic in a City.

Predicting the evolution of a pandemic requires precise understanding of the pathogen and disease progression, the susceptible population group, means of transmission, and possible control mechanisms. It has been a significant challenge as Covid-19 virus (SARS-CoV-2 family) is not well understood yet; the entire human population is susceptible, and the virus transmits easily through airborne particles. Given its size and connectedness, it is not feasible to test the entire population and to isolate the infected individuals. Moreover, rapid and continuous mutation of virus open up the possibility of reinfection. As a result, the evolution of pandemic is not uniform and in-step throughout the world but is significantly influenced by local characteristics pertaining to people, places, dominant virus strain, extent of vaccination, and adherence to pandemic control interventions. Traditional macro-modelling techniques, such as variations of SEIR models, provide only a coarse-grained, 'lumped up' understanding of the pandemic which is not enough for exploring and understanding possible fine-grained factors that are effective for controlling the Covid-19 pandemic. This paper explores the problem space from a system theoretic perspective and presents a fine-grained city digital twin as an in-silico experimentation aid to understand the complex interplay of factors that influence infection spread and also help in controlling the Covid-19 pandemic. Our focus is not to speculate the possibility of the next wave or how the next wave may look like. Instead, we systematically seek answers to questions such as: what are indicators should we consider for a future wave? What are the parameters that may influence those indicators? When and why should they be tweaked (in terms of interventions) to control unacceptable situations? We validate our approach on the second and third waves of Covid-19 pandemic in Pune city.

Socio-demographic factors associated with loss to follow-up of HIV-infected women attending a private sector PMTCT program in Maharashtra, India.

Currently, 40% of HIV-infected women enrolled in national prevention of mother-to-child transmission (PMTCT) program in India are loss to follow-up (LTF) before they can receive single dose Nevirapine. To date no study from India has examined the reasons for inadequate utilization of PMTCT services. This study sought to examine the socio-demographic factors associated with LTF of HIV-infected women enrolled during 2002-2008 in a large-scale private sector PMTCT program in Maharashtra, India. Data on HIV-infected women who were enrolled during pregnancy (N=734) and who reported live birth (N=770) were used to analyze factors associated with LTF before delivery and after delivery, respectively. Univariate and multivariate analyses were conducted to estimate the associations between being LTF and socio-demographic factors using generalized linear models. Eighty (10.9%) women were LTF before delivery and 151 (19.6%) women were LTF after delivery. Women with less than graduate level education (RR = 6.32), from a poor family (RR = 1.61), who were registered after 20 weeks of pregnancy (RR = 2.02) and whose partners were HIV non-infected or with unknown HIV status (RR = 2.69) were more likely to be LTF before delivery. Similarly, the significant factors for LTF after delivery were less than graduate level education (RR = 1.82), poor family (RR = 1.42), and registration after 20 weeks of pregnancy (RR = 1.75). This study highlights the need for innovative and effective counseling techniques for less educated women, economic empowerment of women, better strategies to increase uptake of partner's HIV testing, and early registration of women in the program for preventing LTF in PMTCT programs. This need for innovative counseling techniques is even greater for PMTCT programs in the public health sector as the women accessing care in the public sector are likely to be less educated and economically more deprived.

Love, sex, and commitment: relationship choices and trajectories among unmarried youth in India.

There is limited research in India to understand young people's decision-making processes about intimate relationships before marriage. This paper, adopting a life course perspective, explains relationship choices and diachronic trajectories of relationships from adolescence to young adulthood. Retrospective data were collected from 1240 never married 20-29-year-old men and women living in Pune using a relationships history calendar. All the relationships from 10 years of age onwards were plotted on the calendar, and information on predictor variables was collected through structured questionnaires. Data were analysed using descriptive statistics. Sequence analysis approach was used to identify different typologies. Overall, 76% of the participants reported having at least one relationship. More women compared to men (84% vs 70%) ever had a relationship. The median age of starting the first relationship was 17 years for women and 18 for men. Different relationship types were reported, such as "serious", casual, "friends with benefit", and "exploring". The level of emotional involvement, commitment, and physical intimacy significantly differed in different relationship types with significant gender differences. Four typologies of relationships were observed, labelled as (1) Commitment-No sex (N = 187); (2) Commitment-Sex-Some exploration (N = 189); (3) No commitment-Exploration (N = 281), and (4) No relationship (N = 583). Compared to men, women were more likely to follow the trajectory of "Commitment-No sex" (RR 2.13, CI 1.5-3.03). Family environment was significantly related to young people's relationship choices. The findings strongly suggest the need to adopt a developmental perspective towards intimate relationships to understand and address the vulnerabilities of young people across the life course.

An Agent-Based Digital Twin for Exploring Localized Non-pharmaceutical Interventions to Control COVID-19 Pandemic.

The COVID-19 epidemic created, at the time of writing the paper, highly unusual and uncertain socio-economic conditions. The world economy was severely impacted and business-as-usual activities severely disrupted. The situation presented the necessity to make a trade-off between individual health and safety on one hand and socio-economic progress on the other. Based on the current understanding of the epidemiological characteristics of COVID-19, a broad set of control measures has emerged along dimensions such as restricting people's movements, high-volume testing, contract tracing, use of face masks, and enforcement of social-distancing. However, these interventions have their own limitations and varying level of efficacy depending on factors such as the population density and the socio-economic characteristics of the area. To help tailor the intervention, we develop a configurable, fine-grained agent-based simulation model that serves as a virtual representation, i.e., a digital twin of a diverse and heterogeneous area such as a city. In this paper, to illustrate our techniques, we focus our attention on the Indian city of Pune in the western state of Maharashtra. We use the digital twin to simulate various what-if scenarios of interest to (1) predict the spread of the virus; (2) understand the effectiveness of candidate interventions; and (3) predict the consequences of introduction of interventions possibly leading to trade-offs between public health, citizen comfort, and economy. Our model is configured for the specific city of interest and used as an in-silico experimentation aid to predict the trajectory of active infections, mortality rate, load on hospital, and quarantine facility centers for the candidate interventions. The key contributions of this paper are: (1) a novel agent-based model that seamlessly captures people, place, and movement characteristics of the city, COVID-19 virus characteristics, and primitive set of candidate interventions, and (2) a simulation-driven approach to determine the exact intervention that needs to be applied under a given set of circumstances. Although the analysis presented in the paper is highly specific to COVID-19, our tools are generic enough to serve as a template for modeling the impact of future pandemics and formulating bespoke intervention strategies.

Neurosymptomatic cerebrospinal fluid escape in HIV-2: a case report.

Cerebrospinal fluid (CSF) escape phenomenon is widely studied and documented in HIV-1. However, hardly anything is known about progressive neurologic disease in otherwise well-controlled HIV-2 infection. We present a case of neurosymptomatic CSF escape in HIV-2 infection from India.

"Now What?" to "So What!": Journey with Perinatally HIV Infected Adolescents Transitioning to Adulthood.

Adolescents living with HIV (ALHIV) struggle with questions pertaining to their future; contemplating "Now what?" The authors, a nongovernmental organization from India, designed residential workshops for ALHIV to provide them the space to share concerns and draw support from peers. This increased their self-belief and agency, induced voluntarism, and resulted in formation of a support group, "So What!" The members volunteered in planning a similar workshop for their peers and also shared their experiences of disclosure in the form of a booklet. Active involvement of ALHIV could be a key strategy to address the needs of ALHIV.

Growth Patterns of HIV Infected Indian Children in Response to ART: A Clinic Based Cohort Study.

OBJECTIVE: To describe catch-up growth after antiretroviral therapy (ART) initiation among children living with human immunodeficiency virus (CLHIV), attending a private clinic in India. METHODS: This is a retrospective analysis of data of CLHIV attending Prayas clinic, Pune, India. Height and weight z scores (HAZ, WAZ) were calculated using WHO growth charts. Catch-up growth post-ART was assessed using a mixed method model in cases where baseline and at least one subsequent follow-up HAZ/WAZ were available. STATA 12 was used for statistical analysis. RESULTS: During 1998 to 2011, 466 children were enrolled (201 girls and 265 boys; median age = 7 y). A total of 302 children were ever started on ART; of which 73 and 76 children were included for analysis for catch up growth in WAZ and HAZ respectively. Median WAZ and HAZ increased from -2.14 to -1.34 (p = 0.007) and -2.42 to -1.94 (p = 0.34), respectively, 3 y post ART. Multivariable analysis using mixed model (adjusted for gender, guardianship, baseline age, baseline WAZ/HAZ, baseline and time varying WHO clinical stage) showed gains in WAZ (coef = 0.2, 95 % CI: -0.06 to 0.46) and HAZ (coef = 0.49, 95 % CI: 0.21 to 0.77) with time on ART. Lower baseline WAZ/HAZ and older age were associated with impaired catch-up growth. Children staying in institutions and with baseline advanced clinical stage showed higher gain in WAZ. CONCLUSIONS: The prevalence of stunting and underweight was high at ART initiation. Sustained catch-up growth was seen with ART. The study highlights the benefit of early ART in achieving normal growth in CLHIV.

Effect of highly active antiretroviral treatment (HAART) during pregnancy on pregnancy outcomes: experiences from a PMTCT program in western India.

Previous research regarding the effect of highly active antiretroviral treatment (HAART) on pregnancy outcomes shows conflicting results and is predominantly situated in developed countries. Recently, HAART is rapidly being scaled up in developing countries for prevention of mother-to-child transmission (PMTCT). This study compared adverse pregnancy outcomes among HIV infected women (N=516) who received either HAART (N=192)--mostly without protease inhibitor--or antepartum azidothymidine (AZT) with intrapartum nevirapine (N=324) from January 2008 to March 2012 through a PMTCT program in western India. We analyzed the effect of HAART on preterm births, low birth weight, and all adverse pregnancy outcomes combined using univariate and multivariate logistic regression models. Women on HAART had 48% adverse pregnancy outcomes, 25% preterm births, and 34% low birth weight children compared to respectively 32%, 13%, and 22% among women on AZT. Women receiving HAART were more likely to have adverse pregnancy outcomes and preterm births compared to women receiving AZT. Preconception HAART was significantly related to low birth weight children. This study demonstrated increased risk of adverse pregnancy outcomes with protease inhibitor excluded HAART. Prospective studies assessing the impact of HAART on MTCT as measured in terms of HIV-free survival among children are needed.

Declining HIV prevalence among women attending antenatal care in Pune, India.

A declining prevalence of HIV among young women has been reported by the public sector implementing prevention of mother-to-child transmission (PMTCT) programmes, sentinel surveillance sites and research institutions in India. However, there are no reports evaluating such trends from the private healthcare sector. This study is a retrospective analysis of data collected by PRAYAS as a part of the PMTCT programme at Sane Guruji Hospital (SGH), a secondary care hospital in Pune, India. Women attending the antenatal clinic at SGH were screened for HIV following a group counselling session, with an option to opt out. Between January 2003 and March 2008, the overall HIV prevalence was 111/17 578 (0.6%, 95% CI 0.5-0.7%). The HIV prevalence among antenatal women was 1.1% in 2003 and 0.2% in 2008 (i.e. 82% decline in HIV prevalence over the 5-year period) and the odds ratio (OR) of HIV prevalence declined by 0.24 per year from 2003 to March 2008 (OR=0.76, 95% CI 0.69-0.87; P<0.001). The risk of having HIV infection was significantly higher in women aged ≥ 24 years and those who were uneducated. To our knowledge, this is the first report from any private sector health system in India documenting a declining HIV prevalence among antenatal women. Characterising the risk profile of this small percentage of at-risk women will help in planning prevention strategies.
