Praziquantel Treatment

Schistosomiasis haematobia or urinary schistosomiasis is one of the main public health problems in Africa and the Middle East. A single dose of 40 mg praziquantel per kg body weight continues to be the treatment of choice for this infection. The aims of this follow-up were to study the post-treatment course of a patient infected with S. haematobium and not submitted to re-exposure, and to identify complications of the disease and/or therapeutic failure after praziquantel treatment by histopathological analysis. Treatments were repeated under medical supervision to ensure the correct use of the drug. In view of the suspicion of lesions in cystoscopy, the patient was submitted to bladder biopsy. The histopathological characteristics observed in biopsies obtained, after each treatment, indicated viability of parasite eggs and activity of granulomas.

Urinary schistosomiasis is considered a major public health parasitic disease in African communities. Prior to this study, Nsugbe community was not considered endemic for the disease and as such was not involved in Praziquantel-Preventive Chemotherapy (PC). Longitudinal study of 281 consented pupils aged 5-16 years was carried out with aim of determining the status of urinary schistosomiasis. Urinalysis laboratory test strip, urine filtration technique and syndromic diagnosis were used for the confirmation of the presence of haematuria in urine samples, identification of Schistosoma haematobium ova and the confirmation of female genital schistosomiasis (FGS), respectively. Risk factors for urinary schistosomiasis infection were determined using pre-tested structured questionnaire. Data were analyzed using Minitab 17 software and intensity of infection categorized following World Health Organization (WHO) recommendations. Of the 281 pupils, 117 (42%) were males and 164 (58%) were females with mean age of 9 years. At baseline, an overall prevalence of 0.4% (1/281) which was of light intensity was established. At follow-up, an overall prevalence of 2.1% (6/281) which was of both light (16.7%) and heavy infection (83.3%) was established. The result of the clinical examination showed eggs of S. haematobium in and around the vaginal area indicating FGS of a female pupil aged 12 years. This was treated. Identified risk factors for S. haematobium infection in the community include water-contact activities, ignorance, source of water supply among others. The study revealed the need for an all inclusive mass administration of Praziquantel-PC in the study community for effective control and possible elimination.

The transmission of some schistosome parasites is dependent on the planorbid snail hosts. Bulinus truncatus is important in urinary schistosomiasis epidemiology in Africa. Hence, there is a need to define the snails’ phylogeography. This study assessed the population genetic structure of B. truncatus from Giza and Sharkia (Egypt), Barakat (Sudan) and Madziwa, Shamva District (Zimbabwe) using mitochondrial cytochrome oxidase subunit 1 gene (COI) and internal transcribed spacer 1 (ITS 1) markers. COI was sequenced from 94 B. truncatus samples including 38 (Egypt), 36 (Sudan) and 20 (Zimbabwe). However, only 51 ITS 1 sequences were identified from Egypt (28) and Sudan (23) (because of failure in either amplification or sequencing). The unique COI haplotypes of B. truncatus sequences observed were 6, 11, and 6 for Egypt, Sudan, and Zimbabwe, respectively. Also, 3 and 2 unique ITS 1 haplotypes were observed in sequences from Egypt and Sudan respectively. Mitochondrial DNA sequences from Sudan and Zimbabwe indicated high haplotype diversity with 0.768 and 0.784, respectively, while relatively low haplotype diversity was also observed for sequences from Egypt (0.334). The location of populations from Egypt and Sudan on the B. truncatus clade agrees with the location of both countries geographically. The clustering of the Zimbabwe sequences on different locations on the clade can be attributed to individuals with different genotypes within the population. No significant variation was observed within B. truncatus populations from Egypt and Sudan as indicated by the ITS 1 tree. This study investigated the genetic diversity of B. truncatus from Giza and Sharkia (Egypt), Barakat area (Sudan), and Madziwa (Zimbabwe), which is necessary for snail host surveillance in the study areas and also provided genomic data of this important snail species from the sampled countries.
