    Acceptability and implementation considerations of the patient-collected rectal swab for sexually transmitted infections testing among men who have sex with men and transgender women in Kigali, Rwanda

    by Jean Olivier Twahirwa Rwema, Nneoma E. Okonkwo, Matthew M. Hamill, Carrie E. Lyons, Neia Prata Menezes, Jean Damascene Makuza, Julien Nyombayire, Gallican Nshogoza Rwibasira, Aflodis Kagaba, Patrick S Sullivan, et al.

    Background: Rectal sexually transmitted infections (STI) are prevalent among men who have sex with men (MSM) and transgender women (TGW). Self-collection of rectal specimens is widely used globally, but limited data exist on its implementation in Africa. We report experiences of MSM/TGW self-collecting rectal STI specimens in Kigali. Methods: From March to August 2018, 738 MSM/TGW were recruited in a cross-sectional study using respondent-driven sampling in Kigali. We tested for Neisseria gonorrhea and Chlamydia trachomatis using the Cepheid GeneXpert CT/NG platform on self-collected rectal swabs. Likert scales assessed self-collection difficulty and comfort. Ordered logistic regression analyses were performed to characterize factors associated with self-collection difficulty. Results: Overall, 14%(106) identified as TGW. In total, 78%(577) found rectal swab self-collection easy/very easy, while 15%(108) found it difficult/very difficult. Most, 92%(679), were comfortable/very comfortable with the test, and 98%(730) said they would repeat the test in the future. In multivariable RDS-adjusted analyses, discomfort with the swab was positively associated with difficulty in self-collection (adjusted cumulative odds ratios ((aCOR): 7.9(95%CI: 4.9-12.8)) and having a prevalent rectal STI (aCOR: 4.19, 95%CI: 2.02-8.72) was significantly associated with difficulty. Furthermore, 10%(75) of rectal swabs returned indeterminate results (65 invalid results and 10 errors). Conclusion: Most MSM/TGW found self-collection of rectal swabs easy, comfortable, and collected valid samples. Self-collection of rectal swabs could be used alongside clinic- and community-based STI testing to improve diagnosis and treatment in Rwanda. However, measures to optimize sample collection and processing are needed to reduce the cost and clinical implications of indeterminate results

    Competing health risks associated with the COVID-19 pandemic and early response: A scoping review

    by Stefan Baral, Amrita Rao, Jean Olivier Twahirwa Rwema, Carrie Lyons, Muge Cevik, Anna E. Kågesten, Daouda Diouf, Annette H. Sohn, Refilwe Nancy Phaswana-Mafuya, Adeeba Kamarulzaman, et al.

    Background: COVID-19 has rapidly emerged as a global public health threat with infections recorded in nearly every country. Responses to COVID-19 have varied in intensity and breadth, but generally have included domestic and international travel limitations, closure of non-essential businesses, and repurposing of health services. While these interventions have focused on testing, treatment, and mitigation of COVID-19, there have been reports of interruptions to diagnostic, prevention, and treatment services for other public health threats. Objectives: We conducted a scoping review to characterize the early impact of COVID-19 on HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition. Methods: A scoping literature review was completed using searches of PubMed and preprint servers (medRxiv/bioRxiv) from November 1st, 2019 to October 31st, 2020, using Medical Subject Headings (MeSH) terms related to SARS-CoV-2 or COVID-19 and HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition. Empiric studies reporting original data collection or mathematical models were included, and available data synthesized by region. Studies were excluded if they were not written in English. Results: A total of 1604 published papers and 205 preprints were retrieved in the search. Overall, 8.0% (129/1604) of published studies and 10.2% (21/205) of preprints met the inclusion criteria and were included in this review: 7.3% (68/931) on HIV, 7.1% (24/339) on tuberculosis, 11.6% (26/224) on malaria, 7.8% (19/183) on sexual and reproductive health, and 9.8% (13/132) on malnutrition. Thematic results were similar across competing health risks, with substantial indirect effects of the COVID-19 pandemic and response on diagnostic, prevention, and treatment services for HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition. Discussion: COVID-19 emerged in the context of existing public health threats that result in millions of deaths every year. Thus, effectively responding to COVID-19 while minimizing the negative impacts of COVID-19 necessitates innovation and integration of existing programs that are often siloed across health systems. Inequities have been a consistent driver of existing health threats; COVID-19 has worsened disparities, reinforcing the need for programs that address structural risks. The data reviewed here suggest that effective strengthening of health systems should include investment and planning focused on ensuring the continuity of care for both rapidly emergent and existing public health threats.

    Injection drug use practices and HIV infection among people who inject drugs in Kigali, Rwanda: a cross-sectional study

    by Jean Olivier Twahirwa Rwema, Vianney Nizeyimana, Neia M. Prata, Nneoma E. Okonkwo, Amelia A. Mazzei, Sulemani Muhirwa, Athanase Rukundo, Lisa Lucas, Audace Niyigena, Jean Damascene Makuza, et al.

    Background: In Rwanda, epidemiological data characterizing people who inject drugs (PWID) and their burden of HIV are limited. We examined injection drug use (IDU) history and practices, and HIV infection in a sample of PWID in Kigali. Methods: From October 2019 to February 2020, 307 PWID aged ≥ 18 were enrolled in a cross-sectional study using convenience sampling in Kigali. Participants completed interviewer-administered questionnaires on IDU history and practices and HIV testing. We used Poisson regression with robust variance estimation to assess IDU practices associated with HIV infection and assessed factors associated with needle sharing in the six months preceding the study. Results: The median age was 28 years (IQR 24–31); 81% (251) were males. Female PWID were more likely to report recent IDU initiation, selling sex for drugs, and to have been injected by a sex partner (p < 0.05). In the prior six months, heroin was the primary drug of choice for 99% (303) of participants, with cocaine and methamphetamine also reported by 10% (31/307) and 4% (12/307), respectively. In total, 91% (280/307) of participants reported ever sharing needles in their lifetime and 43% (133) knew someone who died from a drug-related overdose. HIV prevalence was 9.5% (95% CI 6.6–13.3). Sharing needles at least half of the time in the previous six months was positively associated with HIV infection (adjusted prevalence ratio (aPR) 2.67; 95% CI 1.23–5.78). Overall, 31% (94/307) shared needles and 33% (103/307) reused needles in the prior six months. Female PWID were more likely to share needles compared to males (aPR 1.68; 95% CI 1.09–2.59). Additionally, bisexual PWID (aPR 1.68; 95% CI 1.09–2.59), those who shared needles at the first injection (aPR 2.18; 95% CI 1.59–2.99), reused needles recently (aPR 2.27; 95% CI 1.51–3.43) and shared other drug paraphernalia (aPR 3.56; 95% CI 2.19–5.81) were more likely to report recent needle sharing. Conclusion: HIV infection was common in this study. The high prevalence of needle reuse and sharing practices highlights significant risks for onward transmission and acquisition of HIV and viral hepatitis. These data highlight the urgent need for PWID-focused harm reduction services in Rwanda, including syringe services programs, safe injection education, naloxone distribution, and substance use disorder treatment programs and optimizing these services to the varied needs of people who use drugs in Rwanda.


  • The Relationship Between Sexual Behavior Stigma and Depression Among Men Who have Sex with Men and Transgender Women in Kigali, Rwanda: a Cross-sectional Study

    by Nneoma Okonkwo, Jean Olivier Twahirwa Rwema, Carrie Lyons, Benjamin Liestman, Julien Nyombayire, Oluwasolape Olawore, Sabin Nsanzimana, Placidie Mugwaneza, Aflodis Kagaba, Patrick Sullivan, et al.

    To evaluate the role of sexual behavior stigma as a determinant of depressive symptoms among men who have sex with men (MSM) and transgender women (TGW) in Kigali, Rwanda. MSM/TGW aged ≥ 18 years were recruited using respondent-driven sampling (RDS) between March–August, 2018. Mental health was assessed using the Patient Health Questionnaire (PHQ-9). Sexual behavior stigma from friends and family, healthcare workers, and community members was assessed using a validated instrument. Multinomial logistic regression models were used to determine the association between sexual behavior stigma and depressive symptoms and depression. Secondary analyses further compared depression and depressive symptoms among MSM and TGW. Among the 736 participants included, 14% (106/736) identified as TGW. Depression 8.9% (RDS-adjusted, 7.6%; 95% CI, 4.6–10.6) and mild/moderate symptoms of depression 26.4% (RDS-adjusted, 24.1%; 95% CI, 19.4–28.7) were common and higher among TGW compared to MSM (p < 0.001). Anticipated (41%), perceived (36%), and enacted (45%) stigmas were highly prevalent, and were also significantly higher among TGW (p < 0.001). In multivariable RDS-adjusted analysis, anticipated (relative risk ratio (RRR), 1.88; 95% CI, 1.11–3.19) and perceived (RRR, 2.06; 95% CI, 1.12–3.79) stigmas were associated with a higher prevalence of depressive symptoms. Anticipated (RRR, 4.78; 95% CI, 1.74–13.13) and enacted (RRR, 3.09; 95% CI, 1.61–5.93) stigmas were also associated with a higher prevalence of depression. In secondary analyses, the significant differences between MSM and TGW were lost after adjusting for stigma. These data demonstrate a high burden of depressive symptoms and depression among MSM/TGW in Kigali. Conceptually, stigma is a likely antecedent of mental health stress among MSM and TGW suggesting the potential utility of scaling up stigma mitigation interventions to improve the quality of life and mental health outcomes among sexual and gender minority communities in Rwanda.

    Injection Drug use Practices and HIV infection among People Who Inject Drugs in Kigali, Rwanda

    by Jean Olivier Twahirwa Rwema, Vianney Nizeyimana, Neia Prata Menezes, Nneoma E. Okonkwo, Amelia Aibina Mazzei, Sulemani Muhirwa, Athanase Rukundo, Lisa Lucas, Audace Niyigena, Jean Damascene Makuza, et al.

    Background In Rwanda, epidemiological data characterizing people who inject drugs (PWID) and their burden of HIV are limited. We examined injecting drug use (IDU) history, practices, and HIV infection in a sample of PWID in Kigali. Methods From October 2019–February 2020, 322 PWID aged ≥18 were enrolled in a cross-sectional study using convenience sampling in Kigali. Participants underwent a structured interview and HIV testing. We used Poisson regression with robust variance estimation to assess IDU practices associated with HIV infection. Results The median age was 28 years(IQR:24-31) and 81%(248) were male. The median age at first injection was 23 years (IQR:20-27). HIV prevalence was 9.5%(95%CI:8.7-9.3). In the six months preceding the study, heroin was the primary drug of choice for 99%(303); but cocaine and methamphetamine were also reported by 10%(31) and 4%(12) respectively. Furthermore, 31%(94) and 33%(103) of participants, shared or reused needles in the previous six months, respectively. Up to 43%(133) knew someone who died from a drug-related overdose. PWID reporting sharing needles at least half the time in the previous six months had increased likelihood of HIV-infection, compared to those who did not (aPR: 2.67; 95%CI:1.23–5.78). Conclusion HIV infection was common in this sample of PWID in Kigali. The high prevalence of needle reuse and sharing practices highlight significant risk for onward transmission and acquisition of HIV and hepatitis B and C. PWID-focused harm reduction services, including needle and syringe programs, safer injection education, naloxone distribution, and substance use disorder treatment programs, are needed in Rwanda.

  • Cross-sectional assessment of determinants of STIs among men who have sex with men and transgender women in Kigali, Rwanda

    by Jean Olivier Twahirwa Rwema, Sara Herbst, Matthew M Hamill, Benjamin Liestman, Julien Nyombayire, Carrie E Lyons, Placidie Mugwaneza, Jean Damascène Makuza, Patrick Sean Sullivan, Susan Allen, et al.

    Background: STIs among men who have sex with men (MSM) and transgender women (TGW) continue to increase. In Rwanda, STI management relies on syndromic management with limited empirical data characterising the burden of specific STIs among MSM/TGW. This study evaluated the prevalence of syphilis, Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) and associated factors among MSM/TGW in Kigali.Methods: From March to August 2018, 737 MSM/TGW >18 years were enrolled using respondent-driven sampling (RDS). Structured interviews and HIV/STI screening were conducted. Syphilis was screened with rapid plasma reagin confirmed by Treponema pallidum hemagglutination assay. CT/NG were tested by Cepheid GeneXpert. RDS-adjusted multivariable Poisson regression models with robust variance estimation were used to evaluate factors associated with any STI, and determinants of urethral and rectal STIs separately.Results: Prevalence of any STI was 20% (RDS adjusted: 16.7% (95% CI: 13.2% to 20.2%)). Syphilis was 5.7% (RDS adjusted: 6.8% (95% CI: 4.3% to 9.4%)). CT was 9.1% (RDS adjusted: 6.1% (95% CI: 3.9% to 8.4%)) and NG was 8.8% (RDS adjusted: 7.1% (95% CI: 4.9% to 9.2%)). STIs were more common among older MSM and those with HIV (p<0.05). Of CT infections, 67% were urethral, 27% rectal and 6% were dual site. For NG infections, 52% were rectal, 29% urethral and 19% were dual site. Overall, 25.8% (23 of 89) of those with confirmed STI and returned for their results were symptomatic at time of testing.STI symptoms in the previous year (adjusted prevalence ratio (aPR): 1.94 (95% CI: 1.26 to 2.98)) were positively associated with any STI. Being circumcised was negatively associated with any STI (aPR: 0.47 (95% CI: 0.31 to 0.73)). HIV was positively associated with rectal STIs (aPR: 3.50 (95% CI: 1.09 to 11.21)) but negatively associated with urethral STIs.Conclusion: MSM/TGW, especially those living with HIV, are at high risk of STIs in Rwanda with the vast majority being asymptomatic. These data suggest the potential utility of active STI surveillance strategies using highly sensitive laboratory methods among those at high risk given the anatomical distribution and limited symptomatology of STIs observed among Rwandan MSM/TGW.

    Family planning science and practice lessons from the 2018 International Conference on Family Planning

    by Jean Christophe Rusatira, Claire Silberg, Alexandria Mickler, Carolina Salmeron, Jean Olivier Twahirwa Rwema, Maia Johnstone, Michelle Martinez, Jose G. Rimon, Linnea Zimmerman

    Background Since 2009, the International Conference on Family Planning (ICFP) has served as an opportunity for the global reproductive health community to share FP advances and practice lessons in the areas of research, programming, and advocacy. The purpose of this paper was to synthesize the key results and findings presented by members of the FP community at the 2018 ICFP Conference. Methods More than 700 abstracts from all 15 conference tracks were reviewed and 64 abstracts total were selected for this paper based on the novelty and urgency of the findings. The content analysis of conference abstracts were grouped into six final thematic areas. Results 1) Investing in family planning for a lifetime of returns. FP continues to face a shortage of funding. Domestically based and locally owned funding models provide alternative financing solutions. 2) Addressing inequities in family planning for key populations. Various populations still face challenges in accessing FP. Youth-inclusive and user-centered programming show promise in addressing such challenges. 3) Reproductive justice, Unsafe abortions tend to be more common among younger, poor, uneducated and rural women. Legislation is still needed to facilitate a culture of safe abortions. 4) Couple dynamics and decision-making. Couples who share equitable responsibility in decision-making processes are more likely to use contraceptives; couple disagreement influences women’s decisions to covertly use FP. 5) Male involvement in programming. Male champions can successfully promote uptake of FP. Gender-transformative programming promotes gender equity and impacts behavior change. 6) Breakthroughs in novel contraceptives and systems improvement in family planning. Recent advances include user-centered contraceptive technologies that allow for self-administration and information systems which optimize supply chain management. Conclusion The research, advocacy, and programmatic abstracts at ICFP 2018 highlighted research advances, showcased implementation science wins, and provided evidence of critical knowledge gaps in global FP access and use

    The Relationship Between the Global Burden of Influenza From 2017 to 2019 and COVID-19: Descriptive Epidemiological Assessment

    by Stefan David Baral, Katherine Blair Rucinski, Jean Olivier Twahirwa Rwema, Amrita Rao, Neia Prata Menezes, Daouda Diouf, Adeeba Kamarulzaman, Nancy Phaswana-Mafuya, Sharmistha Mishra

    Background: SARS-CoV-2 and influenza are lipid-enveloped viruses with differential morbidity and mortality but shared modes of transmission. Objective: With a descriptive epidemiological framing, we assessed whether recent historical patterns of regional influenza burden are reflected in the observed heterogeneity in COVID-19 cases across regions of the world. Methods: Weekly surveillance data reported by the World Health Organization from January 2017 to December 2019 for influenza and from January 1, 2020 through October 31, 2020, for COVID-19 were used to assess seasonal and temporal trends for influenza and COVID-19 cases across the seven World Bank regions. Results: In regions with more pronounced influenza seasonality, COVID-19 epidemics have largely followed trends similar to those seen for influenza from 2017 to 2019. COVID-19 epidemics in countries across Europe, Central Asia, and North America have been marked by a first peak during the spring, followed by significant reductions in COVID-19 cases in the summer months and a second wave in the fall. In Latin America and the Caribbean, COVID-19 epidemics in several countries peaked in the summer, corresponding to months with the highest influenza activity in the region. Countries from regions with less pronounced influenza activity, including South Asia and sub-Saharan Africa, showed more heterogeneity in COVID-19 epidemics seen to date. However, similarities in COVID-19 and influenza trends were evident within select countries irrespective of region. Conclusions: Ecological consistency in COVID-19 trends seen to date with influenza trends suggests the potential for shared individual, structural, and environmental determinants of transmission. Using a descriptive epidemiological framework to assess shared regional trends for rapidly emerging respiratory pathogens with better studied respiratory infections may provide further insights into the differential impacts of nonpharmacologic interventions and intersections with environmental conditions. Ultimately, forecasting trends and informing interventions for novel respiratory pathogens like COVID-19 should leverage epidemiologic patterns in the relative burden of past respiratory pathogens as prior information.
