SCHISTOSOMIASIS

URINARY

SCHISTOSOMIASIS

Species Schistosoma Mansoni

Schistosoma Japonica

Schistosoma Haematobium
Pathogenesis Inflammatory granulomatous response to allergens from eggs in the colon Inflammatory granulomatous response to allergens from eggs in the bladder and lower ureters.
ACUTE

SCHISTOSOMIASIS

Eosinophilia

Granulomatous Polyps in Colon

Fever, anorexia, weight loss, anemia

Portal Hypertension

Eosinophilia

Hematuria

Terminal Dysuria (pain, difficulty at end of micturition)

Secondary Sites of Infection Eggs go back through portal circulation to liver, causing granulomatous inflammation in liver Eggs go back through systemic circulation (iliacs) to Lungs, causing granulomatous inflammation in lungs.
Sequelae

CHRONIC SCHISTOSOMIASIS

Portal Hypertension leads to Splenomegaly, esophageal varices, and ascites.

Biliary cirrhosis and end-stage liver disease.

Obstructed urine flow results in Hydroureter and Hydronephrosis

Risk for Squamous Cell Carcinoma of the bladder.

CESTODES (TAPEWORMS): Has a scolex (head), proglottids (segments), and suckers.
