Schistosomiasis is the second most common parasitic infection affecting humans, endemic in the Middle East, especially Egypt (1), and in 42 African countries (2). There are 5 main species infecting humans: S. mansoni, S. haematobium, S. japonicum, S. intercalatum, and S. mekongi. S. haematobium is responsible for chronic urogenital infections that may cause serious complications (3). Urinary schistosomiasis is mostly borne in rural and agricultural communities, according to WHO (4)

NF-kappa-B and Protein kinase Cα
Association and changes of NF-kappa-B and Protein kinase Cα as diagnostic markers in chronic schistosomaiasis with or without bladder cancer
2 years
heat shock protein
Changes of heat shock protein HSP 70 as urinary biomarkers for Schistosomal bladder diseases.
1 year
patient has symptoms suggestive of Schistosoma haematobium infection like terminal hematuria and burning micturition
as control group
from patient undergone diagnostic cystoscopy and sampling and confirmed pathologically as Schistosomal bladder cancer.
from patient undergone diagnostic cystoscopy and sampling and confirmed pathologically as non Schistosomal bladder cancer.
Tissue samples: * Histopathological examination: Hematoxylin and Eosin slides will be prepared and examined. * The only dependable criterion for the diagnosis of bilharzial infestation is the microscopic detection of Bilharzia ova in pathological sections. * Pathology (cystitis- cancer and its grade staging will be reported in accordance with the 2022 World Health Organization Classification of Tumors of the Urinary System (17). * To quantify levels of Nuclear factor kappa B and protein kinase c α: * Immunohistochemistry according to the manufacturer's instructions.
Male and female patients of different age groups known to suffer from cystitis and bladder cancer regardless results from schistosomal infection or any other causes.
