Using HIV and Hepatitis C Molecular Epidemiology to Investigate Assisted Partner Services Recruitment Among People Who Inject Drugs in Kenya.

Sexual and/or injecting partners of people who inject drugs (PWID) may have an elevated risk of HIV infection either from sharing a transmission network or an epidemiological environment. We estimated the degree of similarity between HIV and hepatitis C (HCV) sequences from PWID and their partners to assess whether partner-based recruitment identifies sexual or injecting partners within transmission networks. We used assisted partner services (APS) to recruit sexual and injecting partners of PWID living with HIV in Kenya and evaluated trends in the TN93 distances (an adjusted measure of sequence similarity) of the HIV-1 and HCV sequences from partner pairs.

A phylogenetic assessment of HIV-1 transmission trends among people who inject drugs from Coastal and Nairobi, Kenya.

Although recent modeling suggests that needle-syringe programs (NSPs) have reduced parenteral HIV transmission among people who inject drugs (PWID) in Kenya, the prevalence in this population remains high (∼14-20%, compared to ∼4% in the larger population). Reducing transmission or acquisition requires understanding historic and modern transmission trends, but the relationship between the PWID HIV-1 sub-epidemic and the general epidemic in Kenya is not well understood. We incorporated 303 new (2018-21) HIV-1 sequences from PWID and their sexual and injecting partners with 2666 previously published Kenyan HIV-1 sequences to quantify relative rates and direction of HIV-1 transmissions involving PWID from the coast and Nairobi regions of Kenya.

Experience and challenges delivering hepatitis C virus treatment for people who inject drugs in Kenya.

Despite having a higher risk of hepatitis C virus (HCV) infections, people who inject drugs (PWID) in sub-Saharan Africa (SSA) have limited access to HCV treatment. There is scarce literature on treatment delivery modalities that overcome logistical and financial barriers. We utilized different service delivery modalities to provide direct-acting antivirals (DAAs) to PWIDs infected with HCV through methadone clinics and needle and syringe program (NSP) sites in Kenya.

HIV testing services and HIV self-testing programming within emergency care in Kenya: a qualitative study of healthcare personnel to inform enhanced service delivery approaches.

In Kenya, persons insufficiently engaged in HIV Testing Services (HTS) are often treated in emergency departments (ED). There are limited data from healthcare workers on ED-HTS. A qualitative study was completed to understand challenges and facilitators for ED-HTS and HIV self-testing (HIVST).

"We only trust each other": A qualitative study exploring the overdose risk environment among persons who inject drugs living with HIV in Nairobi, Kenya.

In Kenya, overdose remains a major public health concern with approximately 40% of persons who inject drugs (PWID) reporting personal overdoses. PWID living with HIV (PWID-LH) are particularly vulnerable to experiencing fatal and non-fatal overdoses because of the surrounding physical, social, economic, and political environments, which are not fully understood in Kenya. Through qualitative inquiry, this study characterizes Kenya's overdose risk environment.

Defining a screening tool for post-traumatic stress disorder in East Africa: a penalized regression approach.

Background: Scalable PTSD screening strategies must be brief, accurate and capable of administration by a non-specialized workforce.

Methods: We used PTSD as determined by the structured clinical interview as our gold standard and considered predictors sets of (a) Posttraumatic Stress Checklist-5 (PCL-5), (b) Primary Care PTSD Screen for the DSM-5 (PC-PTSD) and, (c) PCL-5 and PC-PTSD questions to identify the optimal items for PTSD screening for public sector settings in Kenya. A logistic regression model using LASSO was fit by minimizing the average squared error in the validation data.

Efficacy of assisted partner services for people who inject drugs in Kenya to identify partners living with HIV and hepatitis C virus infection: a prospective cohort study.

Background: People who inject drugs are at increased risk of both HIV and hepatitis C virus (HCV) infections but face barriers to testing and engagement in care. Assisted partner services are effective in locating people with HIV but are understudied among people who inject drugs. We assessed whether assisted partner services could be used to find, test for HIV and HCV infections, and link to care the partners of people who inject drugs in Kenya.

Virologic Nonsuppression and HIV Drug Resistance Among People Who Inject Drugs and Their Sexual and Injecting Partners in Kenya.

We evaluated the prevalence and correlates of HIV viral nonsuppression and HIV drug resistance (HIV-DR) in a cohort of people who inject drugs living with HIV (PWID-LH) and their sexual and injecting partners living with HIV in Kenya. HIV-DR testing was performed on participants with viral nonsuppression. Of 859 PWID-LH and their partners, 623 (72.

Prevalence and correlates of violence among sexual and injecting partners of people who inject drugs living with HIV in Kenya: a cross-sectional study.

Background: In Kenya, violence is common among people who inject drugs (PWID) living with HIV and their sexual and injecting partners and may lead to decreased uptake of HIV services, increased HIV risk behaviors, and increased HIV transmission. Violence is defined as any physical harm, threatened harm, or forced sexual acts inflicted on a person in the past year. Understanding the nature of violence and its correlates among PWID and their partners will inform population-specific public health interventions and policy recommendations.

Simulated patient training to improve youth engagement in HIV care in Kenya: A stepped wedge cluster randomized controlled trial.

Youth living with HIV (YLHIV) report that negative interactions with health care workers (HCWs) affects willingness to return to care. This stepped wedge randomized trial evaluated effectiveness of a standardized patient actor (SP) HCW training intervention on adolescent engagement in care in Kenya. HCWs caring for YLHIV at 24 clinics received training on adolescent care, values clarification, communication, and motivational interviewing, with 7 SP encounters followed by facilitated feedback of videotaped interactions.

Oral Pre-Exposure Prophylaxis (PrEP) Awareness and Acceptability Among Persons who Inject Drugs (PWID) in Kenya: A Qualitative Investigation.

Background: People who inject drugs (PWID) are disproportionately affected by HIV despite the availability of multiple efficacious biomedical prevention interventions including oral pre-exposure prophylaxis (PrEP). Little is known about the knowledge, acceptability, and uptake of oral PrEP among this population in Kenya. To inform the development of oral PrEP uptake optimization interventions for PWID in Kenya, we conducted a qualitative assessment to establish oral PrEP awareness and willingness to take PrEP by this group in Nairobi City.

SARS-CoV-2 antibody prevalence, correlates, and access to harm reduction services among people who inject drugs living with and without HIV and their partners in Kenya.

Background: In sub-Saharan Africa many people who inject drugs (PWID) are living with undiagnosed or untreated HIV and experience high levels of poverty and conditions that can contribute to worse outcomes from SARS-CoV-2 infection. Identifying the burden of SARS-CoV-2 infection in marginalized populations like PWID may contribute to controlling the pandemic.

Methods: This is a nested cross-sectional study within an ongoing cohort study that recruits PWID living with HIV and their injecting and/or sexual partners at needle and syringe program sites and methadone clinics in Kenya.

'My people perish for lack of knowledge': barriers and facilitators to integrated HIV and hypertension screening at the Kenyatta National Hospital, Nairobi, Kenya.

Introduction: HIV and cardiovascular disease (CVD) are the two main causes of death in Kenya with hypertension as CVD's leading risk factor and HIV infection a risk factor for hypertension. We qualitatively evaluated the feasibility of integrated HIV and hypertension screening at Kenyatta National Hospital.

Methods: We conducted two focus group discussions (FGDs) in November 2020 (female FGD: n=7; male FGD: n=8) to elicit facilitators, barriers and viability of integrated diagnosis and management of both conditions at HIV testing service (HTS) facilities.

Occupational roles and risks of community-embedded peer educators providing HIV, hepatitis C and harm reduction services to persons who inject drugs in Nairobi, Kenya.

Background: In Kenya, harm reduction organizations have adopted evidence-based peer educator (PE) programs, where former people who inject drugs (PWID) serve as community health liaisons to engage PWID in HIV, HCV and harm reduction services. While PEs play an integral role in healthcare delivery, little data exists on their roles, risks and experiences working with PWID, which may be used to inform local harm reduction policy.

Methods: PE's from two harm reduction sites in Nairobi were randomly and purposively selected to participate in semi-structured in-depth interviews.

Usability and acceptability of oral fluid hepatitis C self-testing among people who inject drugs in Coastal Kenya: a cross-sectional pilot study.

Background: People who inject drugs (PWID) are disproportionally affected by hepatitis C virus (HCV) infection and many remain undiagnosed. HCV self-testing (HCVST) may be an effective approach to increase testing uptake, but has rarely been used among PWID. We assessed the usability and acceptability of HCVST among PWID in Kenya.

"They have given you the morale and confidence:" adolescents and young adults want more community-based oral HIV self-testing options in Kenya.

Community-based delivery of oral HIV self-testing (HIVST) may expand access to testing among adolescents and young adults (AYA). Eliciting youth perspectives can help to optimize these services. We conducted nine focus group discussions (FGDs) with HIV negative AYA aged 15-24 who had completed oral HIVST following community-based distribution through homes, pharmacies, and bars.

":" Training Satisfaction and Subsequent Practice among Health Providers Participating in a Standardized Patient Actor Training to Improve Adolescent Engagement in HIV Care.

Background: Poor health care worker (HCW) interactions with adolescents negatively influence engagement in HIV care. We assessed the impact of standardized patient actor training on HCW competence in providing adolescent HIV care in Kenya.

Methods: We conducted pre-post cross-sectional surveys and qualitative exit interviews during a stepped wedge randomized trial.

Characteristics associated with HIV and hepatitis C seroprevalence among sexual and injecting partners of HIV positive persons who inject drugs in Nairobi and coastal Kenya.

Background: Persons who inject drugs (PWID) have higher HIV and hepatitis C virus (HCV) seroprevalence than the general population in many parts of sub-Saharan Africa (SSA). The seroprevalences of HIV and HCV are also higher in coastal Kenya than in Nairobi. Understanding drivers of regional HIV and HCV variation among PWID in Kenya may inform population-specific prevention interventions.

Kenyan HIV Clinics With Youth-Friendly Services and Trained Providers Have a Higher Prevalence of Viral Suppression Among Adolescents and Young Adults: Results From an Observational Study.

Sustained viral suppression in adolescents and young adults living with HIV (AYALWH) is necessary for epidemic control. We evaluated facility and individual correlates of viral suppression using programmatic data from AYALWH between ages 10 and 24 years at 24 HIV clinics in Kenya. Binomial regression was used to evaluate correlates of viral load (VL) suppression (<1,000 copies/ml).

Barriers and facilitators of HIV and hepatitis C care among people who inject drugs in Nairobi, Kenya: a qualitative study with peer educators.

Background: In Kenya, people who inject drugs (PWID) are disproportionately affected by HIV and hepatitis C (HCV) epidemics, including HIV-HCV coinfections; however, few have assessed factors affecting their access to and engagement in care through the lens of community-embedded, peer educators. This qualitative study leverages the personal and professional experiences of peer educators to help identify HIV and HCV barriers and facilitators to care among PWID in Nairobi, including resource recommendations to improve service uptake.

Methods: We recruited peer educators from two harm reduction facilities in Nairobi, Kenya, using random and purposive sampling techniques.

High Acceptance and Completion of HIV Self-testing Among Diverse Populations of Young People in Kenya Using a Community-Based Distribution Strategy.

Oral HIV self-testing (HIVST) may expand access to testing among hard-to-reach reach adolescents and young adults (AYA). We evaluated community-based HIVST services for AYA in an urban settlement in Kenya. Peer-mobilizers recruited AYA ages 15-24 through homes, bars/clubs, and pharmacies.
