Item Detection of Urinary Tract Pathology in Some Schistosoma haematobium Infected Nigerian Adults(Hindawi Publishing Corporation, 2016-07) Onile, O. S.; Awobode, H. O.; Oladele, V. S.; Agunloye, A. M.; Anumudu, C. I.Screening for Schistosoma haematobium infection and its possible morbidity was carried out in 257 adult participants in Eggua community,Ogun State,Nigeria. Parasitological assessment for the presence of ova of S. haematobiumin urine and abdominopelvic ultrasonographic examination for bladder and secondary kidney pathology were carried out. S. haematobiumprevalence of 25.68% (66/257) was recorded among the participants. There was a significantly higher prevalence of 69.2% of urinary schistosomiasis in the females than the prevalence of 31.8% inmales (𝑃 = 0.902). The intensity of infections was mostly light (55) (21.8%) compared to heavy (10) (3.9%) with themean intensity of 16.7 eggs/10mL urine. Structural bladder pathology prevalence among participants was 33.9%. The bladder and kidney pathologies observed by ultrasound in subjects with S. haematobium infections included abnormal bladder wall thickness (59%), abnormal bladder shape (15.2%), bladder wall irregularities (15.2%), bladder masses (1.5%), bladder calcification (1.5%), and hydronephrosis (3%). Infection with S. haematobium was associated with bladder pathology. Higher frequencies of bladder abnormalities were observed more in the participants with light intensity of S. haematobium infection than in those with heavy infection. More bladder pathology was also seen in women than in men, although this was not statistically significant. In conclusion, there is evidence that the development of bladder pathology may be associated with S. haematobium infection.Item IL4, IL13, GSTM1 and T1 variants and susceptibility to Schistosomiasis and associated bladder pathologies in Eggua, Nigeria(Nigerian Journal of Biotechnology, 2020-06) Onile, O. S.,; Awobode, H. O.; Agunloye, A. M.; Marquez-Duenas, C.; Manning Cela, R. G.; Anumudu, C. I.Failure of the human host to elicit adequate immune responses to the adult Schistosoma haematobium worm and continuous strong inflammatory responses to the eggs have been the main causes of bladder pathology in chronic Schistosomiasis. Identification of susceptibility biomarkers for schistosomiasis- associated bladder pathology is necessary in order to detect genetic factors responsible for the infection and spread of the disease. The aim of this study was to identify candidate-biomarkers for susceptibility to schistosomiasis and its associated pathologies. A total of 371 adult participants, comprising 130 males and 241 females from Eggua community, Ogun State, Nigeria, were randomly recruited into a cross sectional study from August 2012 to May 2014. They were screened for S. haematobium ova and bladder pathologies by microscopy and ultrasonography, respectively. Human host susceptibility to schistosomiasis and its associated bladder pathologies were determined by PCR genotyping of Interleukin (IL4 and IL13) genes, and glutathione-S-transferase (GSTT1 and GSTM1) genes. The overall prevalence of S. haematobium in the population was 29.3% (108/369). Bladder pathologies were observed in 32.3% (117/362) of the population. Polymorphisms in IL 4-590 and IL 13-1055 were observed in 24.1% and 9.3% schistosomiasis cases, respectively. The IL 13-1055 polymorphism did not indicate susceptibility to schistosomiasis in males (OR 0.7, 95% CI 0.3-2.1) but a slight risk was found in females (OR 1.1, 95% CI 0.7-1.7). Participants with GSTM1 and GSTT1 polymorphisms expressed elevated risks of bladder pathologies (OR = 4.3, 95% CI 2.0 - 9.2 and OR = 4.2, 95% CI 1.5 – 12.0, respectively), with the pathology and schistosomiasis group having more GST polymorphisms than bladder pathologies.
