“…For instance, some reports either associated males [35,38,39] or females [40] with the risk of S. haematobium infection while other studies reported no association between gender and the risk of S. haematobium infection. [41] Although limited in evidence, the present result showed high risk of S. haematobium infection among males compared to females in both communities (table 3), perhaps due to the aggressive nature of male children and their natural tendency to play than their female counterparts, who are relatively reserved.…”

Background: Schistosoma haematobium co-infection with S. mansoni and soil-transmitted helminthes afflict most-at-risk populations in endemic communities in the developing world. Aim: This study investigated S. haematobium co-infection with soil-transmitted helminthes, and host risk factors in two communities in the central region of Ghana. Methods: Schools and children were selected by stratified cluster and random sampling methods respectively. A total of 250 school children (aged 5 -> 20 years) were recruited. Teachers issued questionnaires to obtain information on host risk factors, water-contact activities and knowledge of S. haematobium infection. Urine and stool samples were examined for S. haematobium infection and S. mansoni and soil-transmitted helminthes using sedimentation quantitative and direct smear/formol-ether sedimentation concentration techniques respectively. Results: S. haematobium infection (1 -50 eggs/10 ml urine) prevalence at Apewosika and Putubiw were 27.5 % and 17 % respectively. Males were more at risk of S. haematobium infection than females. S. haematobium co-infection with soil-transmitted helminthes (A. lumbricoides, E. histolytica, and T. trichuria) was recorded in Putubiw, with females more at risk than males. Children aged 16-19 and 10-15 were more at risk of S. haematobium infection and helminthic co-infection respectively. Haematuria and proteinuria were predictive of S. haematobium infection. School children had poor knowledge of S. haematobium infection. Water-contact activity was common. Conclusion: S. haematobium prevalence and its co-infection with soil-transmitted helminthes were common in Putubiw. Watercontact activity and poor knowledge about S. haematobium infection were major risk factors. Increased education on preventive and control measures especially in schools is recommended.

“…16,[29][30][31][32][33][34][35][36][37][38] However, these studies have been primarily focused on responses among children and not adults. Doehring and others documented improvement of bladder lesions associated with schistosomiasis among children within 2 months, 29 and found reversibility of urinary tract obstructive findings within 1 year after treatment.…”

“…Ultrasound examinations are carried out in local village structures under field conditions using a portable ultrasound unit (Sonosite 180, Bothell, WA) run on battery power. 16,21 Images were archived either by thermal printing or electronic image capture. Ultrasound examinations are performed and scored by two independent readers of the study team who were unaware of the subject's infection status, using the standardized WHO Niamey protocols for detection of morbidity of the urinary tract caused by S. haematobium.…”

“…[8][9][10] As schistosomiasis control programs based on mass drug treatment have aimed to reduce or prevent morbidity, 11 portable ultrasound examination emerged as a useful tool for diagnosing and monitoring schistosome-associated structural urinary tract disease. [12][13][14][15][16] Beginning in the 1990s, the World Health Organization (WHO) has developed guidelines to standardize the use of ultrasonography for the assessment of schistosomiasis-related morbidity. 17 While earlier studies have reported in some detail on the effects of drug treatment on schistosomiasis-associated urinary tract disease among children, 12 relatively little is known about the impact of treatment of affected adults who live in highly endemic areas where the risk of reinfection and recurrent damage is high.…”

Abstract. Previous population-based studies have examined treatment impact on Schistosoma-associated urinary tract disease among children, but much less is known about longer-term treatment benefits for affected adult populations in areas where risk of recurrent infection is high. In communities in Msambweni, along the Kenya coast, we identified, using a portable ultrasound, 77 adults (aged 17-85) with moderate-to-severe obstructive uropathy or bladder disease due to Schistosoma haematobium. Treatment response was assessed by repeat ultrasound 1-2 years after praziquantel (PZQ) therapy and compared with interval changes among age-and sex-matched infected/treated control subjects who did not have urinary tract abnormalities at the time of initial examination. Of the 77 affected adults, 62 (81%) had improvement in bladder and/or kidney scores after treatment, 14 (18%) had no change, and one (1.3%) had progression of disease. Of the 77 controls, 75 (97%) remained disease free by ultrasound, while two (3%) had apparent progression with abnormal findings on follow-up examination. We conclude that PZQ therapy for S. haematobium is effective in significantly reducing urinary tract morbidity from urogenital schistosomiasis among adult age groups, and affected adults stand to benefit from inclusion in mass treatment campaigns.

“…Fibrotic changes of the urinary tract because of schistosomiasis can easily be identified by US, 58 and findings are described in WHO guidelines for identification and reporting of schistosomiasis. 59 Bladder wall thickening and intravesical masses are common observations; in advanced disease, upper urinary tract obstruction is characterized by dilatation of the renal pelvis ( Figure 5).…”

Abstract. The development of good quality and affordable ultrasound machines has led to the establishment and implementation of numerous point-of-care ultrasound (POCUS) protocols in various medical disciplines. POCUS for major infectious diseases endemic in tropical regions has received less attention, despite its likely even more pronounced benefit for populations with limited access to imaging infrastructure. Focused assessment with sonography for HIV-associated TB (FASH) and echinococcosis (FASE) are the only two POCUS protocols for tropical infectious diseases, which have been formally investigated and which have been implemented in routine patient care today. This review collates the available evidence for FASH and FASE, and discusses sonographic experiences reported for urinary and intestinal schistosomiasis, lymphatic filariasis, viral hemorrhagic fevers, amebic liver abscess, and visceral leishmaniasis. Potential POCUS protocols are suggested and technical as well as training aspects in the context of resourcelimited settings are reviewed. Using the focused approach for tropical infectious diseases will make ultrasound diagnosis available to patients who would otherwise have very limited or no access to medical imaging.
