Next step towards point-of-care molecular diagnosis of female genital schistosomiasis (FGS): evaluation of an instrument-free LAMP procedure

Detection of Schistosoma spp. DNA in gynaecological samples by quantitative real-time polymerase chain reaction (qPCR) is considered to be the reference diagnostic test for female genital schistosomiasis (FGS). However, qPCR needs expensive laboratory procedures and highly trained technicians. Loop-mediated amplification (LAMP) is a more field-friendly isothermal procedure for the detection of parasite-specific DNA, but it still requires electrically powered equipment. Here, we validated a Schistosoma haematobium-specific Sh-LAMP procedure and tested a fully instrument-free isothermal amplification using a novel low-cost, and reusable Temperature-cup (T-cup) device. Specific primers were selected based on published assays, targeting the ribosomal intergenic spacer (IGS) region of S. haematobium. Technical validation of the IGS-Sh-LAMP was performed using 20 negative controls, including DNA extracts of soil-transmitted helminths and S. mansoni, and a 10-fold dilution series (100–10−3) of DNA extracted from a single S. haematobium egg (n=4). For clinical validation, the IGS-Sh-LAMP was tested on 125 DNA samples extracted from vaginal swabs of a previous FGS study in Madagascar. Results were compared with the quantification cycle value (Cq) of the standard ITS-2 targeting qPCR. Single S. haematobium egg DNA up to a 10–2 dilution and an ITS-2 Cq <35 tested positive in the IGS-Sh-LAMP. The specificity was found to be excellent (100%). In the clinical samples, IGS-Sh-LAMP showed comparable results with the qPCR, with 35.2% and 33.6% positives, respectively, and a concordance of 79.2% (99/125). Of the 12 false-negatives, 5 corresponded to the 7 qPCR positive samples with very low DNA levels (Cq ≥35). On the other hand, IGS-Sh-LAMP detected 14 additional cases that were not detected by qPCR. The T-cup IGS-Sh-LAMP performance was evaluated in a representative sub-selection (n=10) of IGS-Sh-LAMP positive clinical samples. The T-cup IGS-Sh-LAMP was found to be a very user-friendly method, but in different runs, it missed 1 to 4 of the 10 IGS-Sh-LAMP positive samples, specifically those with a low DNA load. Our results show that the IGS-Sh-LAMP is a suitable alternative to the ITS-2 qPCR for the diagnosis of FGS in gynaecological samples, with high potential for the T-cup as a fully instrument-free isothermal amplification device for point-of-care diagnosis in low-resource settings.

Female genital schistosomiasis burden and risk factors in two endemic areas in Malawi nested in the Morbidity Operational Research for Bilharziasis Implementation Decisions (MORBID) cross-sectional study.

Female genital schistosomiasis (FGS), caused by the parasite Schistosoma haematobium (Sh), is prevalent in Sub-Saharan Africa. FGS is associated with sexual dysfunction and reproductive morbidity, and increased prevalence of HIV and cervical precancerous lesions. Lack of approved guidelines for FGS screening and diagnosis hinder accurate disease burden estimation. This study evaluated FGS burden in two Sh-endemic areas in Southern Malawi by visual and molecular diagnostic methods. Women aged 15-65, sexually active, not menstruating, or pregnant, were enrolled from the MORBID study. A midwife completed a questionnaire, obtained cervicovaginal swab and lavage, and assessed FGS-associated genital lesions using hand-held colposcopy. 'Visual-FGS' was defined as specific genital lesions. 'Molecular-FGS' was defined as Sh DNA detected by real-time PCR from swabs. Microscopy detected urinary Sh egg-patent infection. In total, 950 women completed the questionnaire (median age 27, [IQR] 20-38). Visual-and molecular-FGS prevalence were 26·9% (260/967) and 8·2% (78/942), respectively. 6·5% of women with available genital and urinary samples (38/584) had egg-patent Sh infection. There was a positive significant association between molecular- and visual-FGS (AOR = 2·9, 95%CI 1·7-5·0). 'Molecular-FGS' was associated with egg-patent Sh infection (AOR = 7·5, 95% CI 3·27-17·2). Some villages had high 'molecular-FGS' prevalence, despite <10% prevalence of urinary Sh among school-age children. Southern Malawi carries an under-recognized FGS burden. FGS was detectable in villages not eligible for schistosomiasis control strategies, potentially leaving girls and women untreated under current WHO guidelines. Validated field-deployable methods could be considered for new control strategies.

Knowledge of female genital schistosomiasis and urinary schistosomiasis among final-year midwifery students in the Volta Region of Ghana.

Female genital schistosomiasis (FGS) is a gynaecological complication of urinary schistosomiasis (US) with an estimated burden of 20-120 million cases in endemic areas. A neglected sexual and reproductive health disease in sub-Saharan Africa, FGS increases susceptibility to sexually transmitted infections including cervical cancer and infertility among other morbidities. However, there appears to be limited FGS knowledge among practicing and pre-service health providers with implications for control. We assessed FGS awareness among final-year midwifery students who would soon be delivering primary maternal and reproductive health care. A cross-sectional study was conducted among 193 randomly selected final-year students from all three midwifery training institutions in the Volta region of Ghana in August/September, 2022. Data on participants' demographics and knowledge of the transmission, signs and symptoms, complications, treatment and prevention of both FGS and US were collected using structured questionnaires. Summary statistics were presented as frequencies, proportions and percentages. Only 23.3% (44/189) of participants had heard about FGS compared to 64% (123/192) for US. Of the former, 42 (95%), 40 (91%) and 36 (81.8%) respectively identified genital itching/burning sensation, bloody vaginal discharge and pelvic pain/pain during intercourse as part of the symptoms of FGS. Less than a third (13/44) and about half (25/44) of those who indicated hearing about FGS knew it can be a risk for ectopic pregnancies and infertility respectively. Majority of these participants, 40 (91%), wrongly selected antibiotics as treatment for FGS while 9 indicated it is prevented by sleeping in insecticide-treated nets. Awareness of FGS was limited among the study participants. The high prevalence of knowledge of some FGS symptoms related to the genitalia needs cautious interpretation. Health care training institutions must make deliberate efforts to highlight FGS in the training of midwives as the condition has diagnostic and management implications for some sexual and reproductive health conditions.

Diagnosis of female genital schistosomiasis and other genital infections in young South African women: challenges in the syndromic approach

IntroductionFemale genital schistosomiasis is a common but neglected disease, which results in symptoms similar to sexually transmitted infections in Schistosoma haematobium-endemic areas of Africa and Middle East. In primary healthcare of low-income countries, healthcare professionals use syndromic management protocols for guidance when treating symptoms of genital infection, due to lack of laboratory resources. These protocols do not include treatment for female genital schistosomiasis, despite the overlap of symptoms. Women are at risk of not receiving the appropriate treatment. The aim of this study was to investigate challenges and missed opportunities when using syndromic management protocols for sexually transmitted infections in female genital schistosomiasis-endemic areas.MethodsThis is a secondary analysis of data from a large cross-sectional prevalence study conducted in 2011 in KwaZulu-Natal, South Africa. Young women in schistosomiasis-endemic areas were asked about genital symptoms and underwent laboratory testing and gynecological examinations to look for common genital infections including female genital schistosomiasis. We used the current South African syndromic management protocols as the basis and analyzed the associations between the reported genital symptoms and the differential diagnoses with logistic regression.ResultsBy use of the syndromic approach the conditions gonorrhea, trichomoniasis and herpes could be identified. The symptom “lower abdominal pain” was significantly associated with documented female genital schistosomiasis. However, the same association was not found with gonorrhea or chlamydia. We found no significant association between reported vaginal discharge syndrome and female genital schistosomiasis or between genital ulcer syndrome and female genital schistosomiasis.DiscussionFemale genital schistosomiasis frequently co-exists with, and mimics other genital infections in rural areas of Sub-Saharan Africa. The management protocols in schistosomiasis endemic countries should include advice on how to diagnose and manage this chronic, waterborne genital condition. There is an urgent need to upscale laboratory and diagnostic resources in low-and middle-income countries and specifically schistosomiasis-endemic areas, to diagnose these common genital infections more accurately and to treat affected women accordingly.

Assessing urogenital schistosomiasis and female genital schistosomiasis (FGS) among adolescents in Anaocha, Anambra State, Nigeria: implications for ongoing control efforts

BackgroundUrogenital schistosomiasis (UgS) remains a persistent health challenge among adolescents in Anambra State, Nigeria, despite ongoing control efforts. Mass praziquantel treatment programs, initiated in 2013, primarily target primary school-aged children (5–14 years old), leaving adolescents (10–19 years old) enrolled in secondary schools vulnerable to urogenital schistosomiaisis. Additionally, the extent of female genital schistosomiasis (FGS), a neglected gynaecological manifestation of UgS remains unclear.MethodologyTo address these gaps, a cross-sectional study was conducted in Anaocha Local Government Area from February to May 2023. Four hundred and seventy consenting adolescents aged 10–19 years were enrolled. Urinalysis including urine filtration was employed to confirm haematuria and detect urogenital schistosomiasis (UGS) among the participants. For females with heavy infections (≥ 50 eggs/10 ml urine), a gynaecologist performed colposcopy examinations, complemented by acetic acid and Lugol’s iodine staining to assess for female genital schistosomiasis (FGS) lesions or other related reproductive health conditions. Socio-demographic data, including information on potential risk factors, were systematically collected using the Kobo ToolBox software, following gender-sensitive data collection guidelines. Data were analysed using SPSS version 25, incorporating descriptive statistics, multinomial logistic regression, odds ratios, and significance testing.ResultsAmong the 470 adolescents (52.8% females, 47.2% males) examined, an overall UgS prevalence of 14.5% was observed, with an average of 5.25 eggs per 10 ml of urine. Females had a slightly higher prevalence (16.1%), and 7.5% had heavy infections. Although gender differences in infection rates were not statistically significant, males had slightly higher odds of infection (OR: 1.332; 95% CI: 0.791–2.244; p-value: 0.280). Adolescents aged 10–14 had the highest prevalence, with significantly increased odds of infection (OR: 1.720; 95% CI: 1.012–2.923; p-value: 0.045). Colposcopy examinations of females with heavy infections revealed FGS lesions and co-infections with Trichomonas vaginalis. Haematuria, though prevalent (24.6%), was not the sole indicator, as those without it faced significantly higher odds of infection (OR: 2.924; 95% CI: 1.731–4.941; p-value: 0.000). Dysuria and genital itching/burning sensation were other UgS and FGS associated symptoms. Direct water contact was associated with higher infection odds (OR: 2.601; 95% CI: 1.007–6.716; p-value: 0.048). Various risk factors were associated with UgS.ConclusionThe study highlights the need for a comprehensive Urogenital Schistosomiasis (UGS) control strategy that includes secondary school adolescents, emphasizes risk factor management, promotes safe water practices, and raises awareness about UGS and Female Genital Schistosomiasis (FGS) among adolescents, thus improving control efforts and mitigating this health challenge in the region.

Illness experiences and mental health challenges associated with female genital schistosomiasis in Cameroon: a gender analysis.

This paper highlights the role of cultural and structural gaps that shape illness experiences of women with manifestations of female genital schistosomiasis (FGS) and their impacts upon mental well-being. Using ethnography, case study narrative accounts of women manifesting symptoms of FGS, as well as interviews with health workers within FGS-endemic rural fishing communities in Cameroon, we present experiences of women affected by FGS, alongside information on FGS health service provision. Our results show how gendered power dynamics in decision making, gendered experiences around menstrual health and structural gaps in service provision, combine and lead to poor mental well-being. Subfertility brings a heavy psychosocial toll from external blame and rejection, exacerbated by internalised stigma and the challenge of not being able to fulfil cultural and gendered social norms. Gender analysis is key to developing context-embedded understanding and addressing FGS-related challenges. With context-specific experiences demonstrating FGS comorbidity with mental ill health, there is a need to prioritise mental health integration at policy level through a person-centred approach. Furthermore, to address stigma and discrimination, campaigns to raise awareness in Cameroon, and beyond, are needed. Cet article met en évidence le rôle des lacunes culturelles et structurelles qui façonnent les expériences des femmes atteintes de schistosomiase génitale féminine (SGF) et leur impact sur le bien-être mental. À l'aide de l'ethnographie, de récits d'études de cas de femmes présentant des symptômes de schistosomiase génitale féminine, et d'entretiens avec des agents de santé au sein de communautés de pêcheurs ruraux endémiques de la schistosomiase génitale féminine au Cameroun, nous présentons les expériences des femmes touchées par le SGF, ainsi que des informations sur les services de santé liés au SGF. Nos résultats montrent comment la dynamique du pouvoir dans la prise de décision, les expériences de la santé menstruelle et les lacunes structurelles dans la fourniture de services, interagissent et conduisent à un manque de bien-être psychologique. La sous-fécondité entraîne un lourd fardeau psychosocial du fait du blâme et de rejet externes auxquelles sont assujetties les personnes souffrant de la maladie, ce qui est exacerbé par la stigmatisation intériorisée et le défi que représente leur incapacité à respecter les normes sociales culturelles et sexospécifiques. L'analyse de genre est essentielle pour développer une compréhension intégrée au contexte et pour relever les défis liés aux SGF. les défis liés à l'ESF. Avec des expériences spécifiques au contexte démontrant la comorbidité de la FGS avec la mauvaise santé mentale, il est nécessaire de donner la priorité à l'intégration de la santé mentale au niveau politique par le biais d'une approche centrée sur la personne. l'intégration de la santé mentale au niveau politique par une approche centrée sur la personne. En outre, pour lutter contre la stigmatisation et la stigmatisation et la discrimination, des campagnes de sensibilisation sont nécessaires au Cameroun et au-delà. En este documento se pone de relieve el papel de las brechas culturales y estructurales que dan forma a las experiencias de enfermedad de las mujeres con manifestaciones de Esquistosomiasis Genital Femenina (EGF), y sus impactos en el bienestar mental. Utilizando la etnografía, estudios de caso mediante relatos narrativos de mujeres que manifiestan síntomas de EGF y entrevistas con trabajadores sanitarios de comunidades pesqueras rurales endémicas en Camerún, presentamos las experiencias de las mujeres afectadas por la EGF, junto con información sobre la prestación de servicios sanitarios para la EGF. Nuestros resultados muestran cómo la dinámica de poder de género en la toma de decisiones, las experiencias de género en torno a la salud menstrual y las deficiencias estructurales en la prestación de servicios se combinan y conducen a un bienestar mental deficiente. La subfertilidad conlleva un alto coste psicosocial debido a la culpa y el rechazo externos, exacerbados por el estigma interiorizado y el reto de no poder cumplir las normas culturales y de género. El análisis de género es clave para desarrollar una comprensión integrada en el contexto y abordarlos retos relacionados con la EGF. Dado que las experiencias específicas de cada contexto demuestran la comorbilidad de las EGF con la enfermedad mental, es necesario priorizar la integración de la salud mental en las políticas a través de un enfoque centrado en la persona. Además, para hacer frente al estigma y la discriminación, son necesarias campañas de sensibilización en Camerún y en otros lugares.

Urinary schistosomiasis among female secondary school students in Ndokwa East Local Government Area in Delta State, Nigeria: Knowledge, risk factors and prevalence

x`Undiagnosed and untreated cases of urinary schistosomiasis in females usually lead to severe gynaecological complications, collectively known as Female Genital Schistosomiasis. Periodic assessment of schistosomiasis in vulnerable endemic communities will prevent late diagnosis and treatment. This study was conducted to determine the prevalence, knowledge, and risk factors of urinary schistosomiasis among female secondary school students in Ndokwa East Local Government Area, Delta State, Nigeria. A Cross-sectional research design and multi-stage sampling technique were used to select 401 female secondary school students in the Ndokwa East Local Government Area. Participants’ urine samples were obtained and examined for Schistosoma haematobium eggs. A questionnaire was administered to collect information on the knowledge of schistosomiasis and exposure to known schistosomiasis risk factors from each participant. Urinary schistosomiasis was not detected in any of the analysed samples. Most students were uneducated (8% had good knowledge) regarding the infection. The absence of egg- patent prevalence in the samples may be due to mass administration of praziquantel to control the disease in the LGA. Knowledge about the disease was low. None of the independent variables was a significant predictor of knowledge about urinary schistosomiasis.

Predictors for participation in mass-treatment and female genital schistosomiasis re-investigation, and the effect of praziquantel treatment in South African adolescents.

Female Genital Schistosomiasis (FGS) causes intravaginal lesions and symptoms that could be mistaken for sexually transmitted diseases or cancer. In adults, FGS lesions [grainy sandy patches (GSP), homogenous yellow patches (HYP), abnormal blood vessels and rubbery papules] are refractory to treatment. The effect of treatment has never been explored in young women; it is unclear if gynaecological investigation will be possible in this young age group (16-23 years). We explored the predictors for accepting anti-schistosomal treatment and/or gynaecological reinvestigation in young women, and the effects of anti-schistosomal mass-treatment (praziquantel) on the clinical manifestations of FGS at an adolescent age. The study was conducted between 2011 and 2013 in randomly selected, rural, high schools in Ilembe, uThungulu and Ugu Districts, KwaZulu-Natal Province, East Coast of South Africa. At baseline, gynaecological investigations were conducted in female learners in grades 8 to 12, aged 16-23 years (n = 2293). Mass-treatment was offered in the low-transmission season between May and August (a few in September, n = 48), in accordance with WHO recommendations. Reinvestigation was offered after a median of 9 months (range 5-14 months). Univariate, multivariable and logistic regression analysis were used to measure the association between variables. Prevalence: Of the 2293 learners who came for baseline gynaecological investigations, 1045 (46%) had FGS lesions and/or schistosomiasis, 209/1045 (20%) had GSP; 208/1045 (20%) HYP; 772/1045 (74%) had abnormal blood vessels; and 404/1045 (39%) were urine positive. Overall participation rate for mass treatment and gynaecological investigation: Only 26% (587/2293) learners participated in the mass treatment and 17% (401/2293) participated in the follow up gynaecological reinvestigations. Loss to follow-up among those with FGS: More than 70% of learners with FGS lesions at baseline were lost to follow-up for gynaecological investigations: 156/209 (75%) GSP; 154/208 (74%) HYP; 539/722 (75%) abnormal blood vessels; 238/404 (59%) urine positive. The grade 12 pupil had left school and did not participate in the reinvestigations (n = 375; 16%). Follow-up findings: Amongst those with lesions who came for both treatment and reinvestigation, 12/19 still had GSP, 8/28 had HYP, and 54/90 had abnormal blood vessels. Only 3/55 remained positive for S. haematobium ova. Factors influencing treatment and follow-up gynaecological investigation: HIV, current water contact, water contact as a toddler and urinary schistosomiasis influenced participation in mass treatment. Grainy sandy patches, abnormal blood vessels, HYP, previous pregnancy, current water contact, water contact as a toddler and father present in the family were strongly associated with coming back for follow-up gynaecological investigation. Challenges in sample size for follow-up analysis of the effect of treatment: The low mass treatment uptake and loss to follow up among those who had baseline FGS reduced the chances of a larger sample size at follow up investigation. However, multivariable analysis showed that treatment had effect on the abnormal blood vessels (adjusted odds ratio = 2.1, 95% CI 1.1-3.9 and p = 0.018). Compliance to treatment and gynaecological reinvestigation was very low. There is need to embark on large scale awareness and advocacy in schools and communities before implementing mass-treatment and investigation studies. Despite challenges in sample size and significant loss to follow-up, limiting the ability to fully understand the treatment's effect, multivariable analysis demonstrated a significant treatment effect on abnormal blood vessels.

The WHO atlas for female-genital schistosomiasis: Co-design of a practicable diagnostic guide, digital support and training.

Up to 56 million young and adult women of African origin suffer from Female Genital Schistosomiasis (FGS). The transmission of schistosomiasis happens through contact with schistosomiasis infested fresh water in rivers and lakes. The transmission vector is the snail that releases immature worms capable of penetrating the human skin. The worm then matures and mates in the blood vessels and deposits its eggs in tissues, causing urogenital disease. There is currently no gold standard for FGS diagnosis. Reliable diagnostics are challenging due to the lack of appropriate instruments and clinical skills. The World Health Organisation (WHO) recommends "screen-and-treat" cervical cancer management, by means of visual inspection of characteristic lesions on the cervix and point-of-care treatment as per the findings. FGS may be mistaken for cervical cancer or sexually transmitted diseases. Misdiagnosis may lead to the wrong treatment, increased risk of exposure to other infectious diseases (human immunodeficiency virus and human papilloma virus), infertility and stigmatisation. The necessary clinical knowledge is only available to a few experts in the world. For an appropriate diagnosis, this knowledge needs to be transferred to health professionals who have minimal or non-existing laboratory support. Co-design workshops were held with stakeholders (WHO representative, national health authority, FGS experts and researchers, gynaecologists, nurses, medical doctors, public health experts, technical experts, and members of the public) to make prototypes for the WHO Pocket Atlas for FGS, a mobile diagnostic support tool and an e-learning tool for health professionals. The dissemination targeted health facilities, including remote areas across the 51 anglophone, francophone and lusophone African countries. Outcomes were endorsed by the WHO and comprise a practical diagnostic guide for FGS in low-resource environments.

Developing and validating a screening tool for female genital schistosomiasis in urban Zambia

BackgroundThe World Health Organization estimates that 56 million women and girls live with female genital schistosomiasis (FGS) in sub-Saharan Africa. FGS is often confused with symptoms of other genital abnormalities, and gold standard diagnosis with colposcopy is infeasible in most health facilities. Schistosomiasis haematobium is endemic in Zambia, yet routine screening or diagnostic efforts for FGS remain unavailable. Our study aimed to develop and pilot test a feasible FGS screening algorithm to implement in Zambian government clinics.Methodology/Principal FindingsWe recruited 499 women from a longitudinal cohort of HIV-negative adult women in Lusaka and Ndola, Zambia. We used demographic, risk factor, and symptom data collected from standardized surveys, gynecological exams, and laboratory tests to develop a screening algorithm for FGS among a derivation cohort (n=349). After cross-validation using 5-fold iterative resampling, the algorithm was applied in a holdout sample of the cohort (n=150). The prevalence of FGS (ascertained by expert review) was 23.4% in the study population. The screening algorithm included childhood and travel exposure to rivers and streams; testing positive for visual inspection of the cervix with acetic acid; hematuria; reporting less than the median average age at sexual debut (&amp;lt;17 years); when asked what diseases can be transmitted via freshwater exposure, reporting ‘none’; being born outside of Lusaka or Copperbelt Province; and reporting occupation as ‘Housekeeper’. The screening algorithm had reasonable discrimination in the derivation cohort (area under the curve [AUC]=0.69, 95% confidence interval [CI]: 0.66-0.79, p-value&amp;lt;0.001). Using a score cut off ≥ 2 the risk algorithm in the derivation cohort had 77% sensitivity, 48% specificity, 35% positive predictive value, and 85% negative predictive value.Conclusions/SignificanceGiven the prevalence of FGS and associated morbidities, improved screening for FGS is imperative. We developed a simple screening algorithm to improve the diagnosis and treatment of FGS among adult women in Zambian government clinics.

Female Genital Schistosomiasis: A Neglected among the Neglected Tropical Diseases.

Schistosomiasis is a neglected parasitic disease linked to water, posing a global public health concern with a significant burden in sub-Saharan Africa. It is transmitted by Schistosoma spp., causing both acute and chronic effects affecting the urogenital or the hepato-intestinal system. Through granuloma formation, chronic schistosomiasis weakens host immunity, heightening susceptibility to coinfections. Notably, female genital schistosomiasis (FGS), a disregarded gynecological condition, adversely affects girls' and women's reproductive health and increases vulnerability to HIV. This review explores the intricate interplay between schistosomiasis and HIV, considering their geographical overlap. We delve into the clinical features of this coinfection, underlying mutual influences on transmission, diagnostic challenges, and therapeutic approaches. Understanding the dynamics of FGS and HIV coinfection is pivotal for integrated healthcare strategies in regions with co-endemicity, aiming to mitigate the impact of the two infections on vulnerable populations.

Minimum service package for the integration of female genital schistosomiasis in sexual and reproductive health services in Kenya

Female genital schistosomiasis (FGS) is caused by chronic Schistosoma hematobium infection. Over 56 million women and girls in sub-Saharan Africa are estimated to be infected with FGS. However, gaps in knowledge of the symptomatology of FGS often lead to misdiagnosis and undertreatment. FGS presents with nonspecific genital symptoms and is likely to be misdiagnosed as a sexually transmitted infection (STI). Recurrent treatment for STIs may result in marital discord, intimate partner violence, and social stigma. Other FGS complications include ectopic pregnancy, infertility, urine incontinence, 3-4-fold increased susceptibility to HIV infection, and persistence of human papillomavirus infection (HPV). A minimum service package (MSP) that is acceptable and feasible for the integration of FGS and sexual and reproductive health (SRH) services is needed. A foundational literature review was conducted to identify service points for FGS and sexual and reproductive health (SRH) service integration. The final MSP was developed through collaborative efforts with stakeholders in various fields associated with FGS and SRH services. The MSP identified four key areas for successful integration of FGS into SRH services including: health literacy, screening and diagnosis, treatment and care, and social inclusion and equity at the community and healthcare facility level. A context-specific integration MSP may be the most efficient, effective, and ethical way to comprehensively address the burden of FGS faced by women and girls in Africa.

Female Genital Schistosomiasis Lesion Resolution Post-Treatment with Praziquantel in Zambian Adults.

We evaluated changes in female genital schistosomiasis (FGS) 6 to 12 months after praziquantel treatment among 43 adult Zambian women. Most women (60%) experienced decreased FGS severity and 23% experienced complete lesion resolution. This is the first study to demonstrate a meaningful effect of praziquantel treatment of FGS in adult women.

Time to bring female genital schistosomiasis out of neglect.

Female genital schistosomiasis (FGS) is a chronic gynaecological disease affecting girls and women in sub-Saharan Africa (SSA), caused by the parasite Schistosoma (S.) haematobium. FGS is associated with sexual dysfunction, reproductive tract morbidity and increased prevalence of HIV and cervical precancer lesions. Key peer-reviewed published literature. FGS screening and diagnosis require costly equipment and specialized training, seldom available in resource-limited settings. FGS surveillance is not included in wider schistosomiasis control strategies. The interplay of FGS with other SRH infections is not fully understood. Integration of FGS within sexual and reproductive health (SRH) control programmes needs to be explored. There are no standardized methods for individual or population-based FGS screening and diagnosis, hindering accurate disease burden estimates and targeted resource allocation. Treatment recommendations rely on public health guidelines, without rigorous clinical evidence on efficacy. Integrating FGS screening with SRH programmes offers an opportunity to reach at-risk women with limited access to healthcare services. Home-based self-sampling coupled with handheld colposcopes operated by primary healthcare workers show promise for FGS diagnosis and surveillance at scale. There is growing interest in decentralizing strategies for FGS screening and diagnosis. The accurate predictions on the 'cost-effectiveness' of these approaches will determine their affordability and feasibility within the overburdened health systems in SSA. Clinical trials are needed to optimize FGS treatment. Longitudinal studies can expand on the epidemiological knowledge on co-morbidities and integration within other SRH interventions.

Improved prevention of female genital schistosomiasis: piloting integration of services into the national health system in Côte d’Ivoire

IntroductionFemale genital schistosomiasis (FGS) is a neglected gynecological condition, putting women at-risk of poor sexual and reproductive health (SRH), including pregnancy complications or infertility. Early treatment of schistosomiasis with praziquantel is important to avoid disease progression to FGS as it is not always possible to reverse these symptoms. However, prevention programs with praziquantel have historically focused on school-aged children. Therefore, there is a gap to provide prevention services for young women in endemic areas, including Côte d’Ivoire.MethodsWe piloted integration of FGS prevention services into routine SRH care in seven health centers (Soubré district, Côte d’Ivoire, November 2020 to April 2021) and enrolled 56 health workers. We used mixed methods including key informant interviews, focus group discussions, and questionnaires to determine effectiveness, feasibility and acceptability of integration across health system decision makers, health workers and female patients (15 to 29 years old). For qualitative data, we used an inductive coding process to analyze themes. We used descriptive statistics to analyze quantitative data.ResultsInterviewed health workers perceived that the integrated services increased access and improved health outcomes for women (15 to 29 years old) due to the more comprehensive approach, although barriers to access included lack of transportation. Female patients surveyed at baseline (n=448) indicated there were no routine FGS prevention services. During the pilot, FGS prevention services were provided to &amp;gt;8500 women at-risk. Health workers interviewed at the end of the pilot indicated they could feasibly provide FGS prevention services as part of routine patient consultations, and they maintained knowledge from training on the key FGS health education points and the consultation processes to follow. The greatest challenge expressed by health workers was the high workload.DiscussionProvision of integrated healthcare in the health center setting is an effective and acceptable way to increase access to prevention services and provide holistic care for women (15 to 29 years old) in this setting in Côte d’Ivoire. Future scale-up will require further streamlining of the strategy, building on existing platforms, whilst ensuring reduced impact on workload and consideration of how to overcome barriers to accessing health centers.

Presence of tissue schistosomiasis in KwaZulu-Natal, South Africa: a retrospective histopathologic review

BackgroundSchistosomiasis affects many parts of the human body including those not usually accessible during routine clinical follow-up. We investigated the presence of schistosomiasis in routine tissue specimens sent to the only public histopathology laboratory in KwaZulu-Natal, South Africa.MethodsThe catchment area for the Department of Anatomical Pathology constitutes 11 million people in 10 districts. We retrospectively reviewed all the histopathology reports for occurrence of schistosomiasis between 1 January 2015 and 30 June 2020.ResultsSchistosomiasis was identified in the appendix, uterine cervix, urinary bladder, lung, liver, fallopian tubes and prostate. During the study period, 725 cases had a diagnosis of schistosomiasis confirmed on histopathology, which equals 0.3% of the total number of specimens sent to the laboratory. Female genital schistosomiasis represented 49.1% (356/725) of the schistosomiasis cases of which 25.1% (182) were from the uterine cervix and 24% (174) from the fallopian tubes. The appendix had 39.7% (289) of all the cases of schistosomiasis. Other organs were urinary bladder (4.4%, 32), lung (3.2%, 23) and liver (2.6%, 19). There were two cases of schistosomiasis in the prostate and four cases in the anorectal region. The main three indications for taking biopsies were acute appendicitis, cervical intraepithelial neoplasia, and sterilization. Majority of the schistosomiasis cases (312) were from eThekwini/Durban metropolitan district, however this represented only 1.2% (312/25 111) of the specimens received from eThekwini/Durban. The districts with the highest percentage positive cases were uMkhanyakude (43/965, 4.5%), followed by Ugu (129/5 251, 2.6%), and King Cetshwayo districts (132/5 360, 2.5%).ConclusionClinicians in the KwaZulu-Natal public health sector hospitals did not suspect schistosomiasis when they submitted patient samples for histopathological investigations. The study indicates the prevalence and the diversity of the body organs affected by schistosomiasis.

Case Report: Three cases of suspected female genital schistosomiasis and precancerous lesions for cervical cancer in a highly endemic country—from clinical management to public health implications

Female genital schistosomiasis (FGS) is a chronic manifestation of schistosomiasis, usually caused by Schistosoma haematobium infection, which can be responsible for infertility, ectopic pregnancy, and abortion, and is associated with an increased prevalence of HIV infection. No screening programs are currently recommended for FGS. Colposcopy, the conventionally suggested diagnostic tool for FGS, is also considered a crucial screening tool for cervical cancer (CC). We performed an experimental screening via colposcopy for FGS at primary healthcare centers (PHCCs) in the Boeny region of Madagascar, allowing for the detection of patients with both FGS signs and HPV-related dysplasia (HPV-dy). All suspected FGS cases were treated with praziquantel on the day of colposcopy, and all images of suspected CC or HPV-dy were re-assessed by a gynecologist and, if needed, patients were then provided with additional colposcopy for histologic diagnosis and treatment. We describe three cases of FGS and HPV-related precancerous lesions detected during the project, discussing the state of art of the relationship between CC, FGS and HPV and the real-life challenges encountered in terms of both patient compliance and the diagnostic and treatment cascade. Despite the current diagnostic limitations, a screening for FGS via colposcopy may contribute to the early identification of CC or precancerous lesions. The addition of visual inspection with acetic acid (VIA) during colposcopy for FGS screening could improve its impact on CC screening. In addition, although there is limited evidence of the effectiveness of praziquantel in FGS, treatment should in any case be proposed for suspicious lesions, given its safety and ease of administration. The benefit of combined screening could be maximised by increasing the availability of good quality services and improve awareness of both diseases among women

Awareness and knowledge of female genital schistosomiasis in a population with high endemicity: a cross-sectional study in Madagascar.

Female genital schistosomiasis (FGS) is a neglected disease with long-term physical and psychosocial consequences, affecting approximately 50 million women worldwide and generally representing an unmet medical need on a global scale. FGS is the chronic manifestation of a persistent infection with Schistosoma haematobium. FGS services are not routinely offered in endemic settings with a small percentage of women at risk receiving adequate care. Madagascar has over 60% prevalence of FGS and no guidelines for the management of the disease. This study aimed to determine FGS knowledge among women and health care workers (HCWs) in a highly endemic area of Madagascar. A convenience sampling strategy was used for this cross-sectional study. Descriptive statistics including proportions and 95% confidence intervals (CI) were calculated, reporting socio-demographic characteristics of the population. Knowledge sources were evaluated descriptively. Binary Poisson regression with robust standard errors was performed; crude (CPR) and adjusted prevalence ratio (APR) with 95% CIs were calculated. A total of 783 participants were included in the study. Among women, 11.3% (n = 78) were aware of FGS while among the HCWs 53.8% (n = 50) were aware of FGS. The highest level of knowledge was observed among women in an urban setting [24%, (n = 31)] and among those with a university education/vocational training [23% (n = 13)]. A lower APR of FGS knowledge was observed in peri-urban [APR 0.25 (95% CI: 0.15; 0.45)] and rural [APR 0.37 (95% CI 0.22; 0.63)] settings in comparison to the urban setting. Most HCWs reported other HCWs [40% (n = 20)] while women mainly reported their family [32% (n = 25)] as being their main source of information in the 6 months prior to the survey. Our study shows limited awareness and knowledge of FGS among population groups in the highly endemic Boeny region of Madagascar. With this study we contribute to identifying an important health gap in Madagascar, which relates to a disease that can silently affect millions of women worldwide. In alignment with the targets of the NTD roadmap, addressing schistosomiasis requires a paradigm shift for its control and management including a greater focus on chronic forms of the disease.

Female genital schistosomiasis, human papilloma virus infection, and cervical cancer in rural Madagascar: a cross sectional study

BackgroundWomen’s health in resource-limited settings can benefit from the integrated management of high-burden diseases, such as female genital schistosomiasis (FGS) and human papilloma virus (HPV)-related cervical cancer. In schistosomiasis-endemic countries such as Madagascar, data on FGS and HPV prevalence are lacking as well as preventive measures for both conditions. This study aims to estimate the prevalence of FGS and HPV in rural Madagascar, and to examine associated risk factors to identify opportunities for improving women’s health.MethodsAfter initial community outreach activities, interested women aged 18–49 years were recruited consecutively in 2021 at three primary health care centers in the district of Marovoay. FGS was detected by colposcopy. Colposcopy images were double-blind reviewed by two independent specialists. A Luminex bead-based assay was performed on cervical vaginal lavage specimens for HPV typing. Crude (CPR) and adjusted prevalence ratios (APR) of associations between selected factors and FGS and HPV positivity were estimated using univariable and multivariable binary Poisson regression with 95% confidence intervals (CIs).ResultsAmong 500 women enrolled, 302 had complete information on FGS and HPV diagnosis, and were thus eligible for analysis. Within the sample, 189 (62.6%, 95% CI: 56.9–68.1) cases of FGS were detected. A total of 129 women (42.7%, 95% CI: 37.1–48.5) tested positive for HPV. In total, 80 women (26.5%, 95% CI: 21.6–31.8]) tested positive for both conditions. No association was observed between FGS and HPV positivity, while previous pregnancy (APR = 0.65, 95% CI: 0.43–0.78) and older age (APR = 0.59, 95% CI: 0.42–0.81) are showing a negative association with HPV infection compared to no previous pregnancy and younger age groups.ConclusionsThe results of the study show that FGS and HPV are highly prevalent in rural Madagascar. The concurrent prevalence of these two conditions requires urgent adaptations of public health strategies to improve women’s health, such as integrated services at primary level of care.Graphical
