Abstract:
Schistosomiasis, a snail-borne disease caused by infection with a trematode parasite of the genus Schistosoma, is one of the most neglected tropical diseases in the world. One of its rare complications is hepatosplenic schistosomiasis which ultimately leads to fibrosis and presinusoidal portal hypertension.
We report a case of a 13-year-old Filipino male from Quezon City with previous one year residence in the endemic island of Leyte, presenting with melena. Diagnostic work-up revealed hepatosplenomegaly and periportal fibrosis with multiple hepatic nodules on ultrasound, positive Schistosoma japonicum eggs on Kato-Katz stool examination technique, and findings of esophageal varices on upper endoscopy. The patient was managed with praziquantel, propranolol, and endoscopic rubber band ligation of the esophageal varices, with note of resolution of bleeding, and improvement on sonographic liver findings.
The degree of liver fibrosis from schistosomiasis is affected by poorly understood mechanisms which affect its severity, progression, and complications, regardless of biosocial factors including egg burden and duration of parasite exposure. This is the first case report on a Filipino adolescent to document significant interval improvement, within four weeks of treatment, of the characteristic fibrotic pattern in hepatosplenic schistosomiasis. Hepatosplenic schistosomiasis is still often missed out as the diagnosis in patients who consult with common symptoms, and high index of suspicion is recommended for those with history of residence in endemic areas. Likewise, treatment focusing on parasite eradication can aid in promptly addressing the resulting fibrosis and its complications.
