Risk factors for Schistosoma mansoni and hookworm in urban farming communities in western Côte d'Ivoire

Abstract Background: Schistosomiasis remains an important public health issue among adults and infected individuals not treated serve as a reservoir of the parasite. Despite this fact, evidence on the epidemiology of schistosomiasis in adults in Côte d’Ivoire is scanty. This study aimed to determine the prevalence and risk factors of schistosomiasis among adults in the Taabo health and demographic surveillance system in the south-central part of Côte d’Ivoire.Methods: A cross-sectional survey was carried out in April and May 2017 in the frame of the “Côte d’Ivoire Dual Burden of Disease Study” (CoDuBu). A total of 901 randomly selected individuals, aged 18-90 years, provided blood, stool and urine samples for the diagnosis of malaria and helminth infections. With an emphasis on schistosomiasis, stool samples were subjected to the Kato-Katz technique for detection of Schistosoma mansoni eggs, while urine samples were examined for eggs of Schistosoma haematobium and circulating cathodic antigen of S. mansoni. Risk factors and morbidity profiles were assessed using health examination and questionnaires. Multinomial logistic regressions were employed to identify independent risk factors and morbidity patterns associated with S. mansoni mono- and co-infections.Results: The prevalence of S. mansoni and S. haematobium was 23.2% and 1.0%, respectively. Most S. mansoni were mono-infections (81.3%). Independent determinants of S. mansoni infection were young age, low socioeconomic status (mono- and co-infection) and poor hygiene practices (co-infection). S. mansoni infection was independently associated with higher pain and symptom scores (mono-infection), poor self-rated health and low healthcare use (co-infection).Conclusions: This study showed that adults represent a substantial reservoir of S. mansoni. To sustain schistosomiasis control and improve people’s wellbeing, it is important to expand preventive chemotherapy from school-aged children to adults, coupled with hygiene and health education.

True Infection

In low-endemicity settings, current tools for diagnosis and surveillance of schistosomiasis are often inaccurate in detecting true infection. We assessed the accuracy of an up-converting phosphor lateral flow circulating anodic antigen (UCP-LF CAA) test and a point-of-care circulating cathodic antigen (POC-CCA) urine cassette test for the diagnosis of Schistosoma mansoni. Our study was conducted in eight schools of western Côte d’Ivoire. Fifty children, aged 9 to 12 years, were enrolled per school. From each child, a single urine specimen and two stool specimens were collected over consecutive days for diagnostic workup. Urine samples were subjected to UCP-LF CAA and POC-CCA tests. From each stool sample, triplicate Kato-Katz thick smears were examined. Overall, 378 children had complete data records. The prevalence of S. mansoni, as assessed by six Kato-Katz thick smears, was 4.0%. The UCP-LF CAA and POC-CCA tests revealed S. mansoni prevalence of 25.4% and 30.7%, respectively, when considering trace results as positive, and prevalence of 23.3% and 10.9% when considering trace results as negative. In the latter case, based on a composite gold standard, the sensitivity of UCP-LF CAA (80.7%) was considerably higher than that of POC-CCA (37.6%) and six Kato-Katz thick smears (13.8%). The negative predictive value of UCP-LF CAA, POC-CCA, and six Kato-Katz thick smears was 92.8%, 79.8%, and 74.1%, respectively. Our results confirm that UCP-LF CAA is more accurate than Kato-Katz and POC-CCA for the diagnosis of S. mansoni in low-endemicity settings.

Spatial Risk

The objectives of this study were (1) to examine risk factors for Schistosoma mansoni infection among schoolchildren living in western Côte d'Ivoire, and (2) to carry forward spatial risk prediction and mapping at non-sampled locations. First, demographic and socio-economic data were obtained from 3818 children, aged 6–16 years, from 55 schools. Second, a single stool sample was examined from each child by the Kato-Katz technique to assess infection status of S. mansoni and its intensity. Third, remotely sensed environmental data were derived from satellite imagery and digitized ground maps. With these databases a comprehensive geographical information system was established. Bayesian variogram models were applied for spatial risk modelling and prediction. The infection prevalence of S. mansoni was 38·9%, ranging from 0% to 89·3% among schools. Results showed that age, sex, the richest wealth quintile, elevation and rainfall explained the geographical variation of the school prevalences of S. mansoni infection. The goodness of fit of different spatial models revealed that age, sex and socio-economic status had a stronger influence on infection prevalence than environmental covariates. The generated risk map can be used by decision-makers for the design and implementation of schistosomiasis control in this setting. If successfully validated elsewhere, this approach can guide control programmes quite generally.

Objectives. Postpartum haemorrhage is one of several direct causes of maternal death in Côte d’Ivoire. It is recurrent in the department of gynaecology and obstetrics at Bouaké University Hospital (CHU de Bouaké), but little is known to date about the underlying risk factors. The present study aims to describe the levels and trends displayed by the risk factors of postpartum haemorrhage before determining the contributing social factors in the aforesaid department. Material and methods. This study is retrospective in nature, concerning the period from 2014 to 2016. Data was obtained from delivery records and through individual interviews. The overall approach adopted is an anthropological one. Results. Postpartum haemorrhage is significant in light of its very high and increasing incidence (22.31%) among multiparous mothers. Within the latter category, fatal complications are a critical problem, with an annual average estimated at 35.98% and on the rise. The overall situation is alarming in view of this progressive deterioration. The persistence of the reproductive morbidity is attributable to various economic, social, cultural, and infrastructural factors. Conclusions. Communicational strategies are proposed as a type of community intervention conducive to social and behavioural change, with multiparous mothers as a priority target group, followed by older mothers in the medium term and by adolescent mothers in the long term. This should raise awareness about high-risk reproductive behaviours and practices as well as the environmental, economic, social, cultural, and infrastructural factors correlated to postpartum haemorrhage, with the ultimate goal of improving the quality and safety of reproductive practices. Keywords: postpartum haemorrhage, reproductive behaviour, high risk, obstetric emergency, maternal morbidity, Côte d’Ivoire.
