Introduction: Schistosomiasis associated pulmonary arterial hypertension belongs to group 1 of the pulmonary hypertension classification and should be considered in any patient with pulmonary hypertension returning from an endemic area.
Case report: A 17-year-old patient was hospitalized for pulmonary hypertension detected during the initial assessment of viral hepatitis B-related cirrhosis with portal hypertension. The initial assessment established the diagnosis of pulmonary hypertension secondary to viral hepatitis B-cirrhosis. The patient's hepatic and haemodynamic condition deteriorated and he was treated with intravenous epoprostenol. This allowed subsequent performance of a liver transplantation. Epoprostenol could then be discontinued. Unexpectedly, histology of the liver explant revealed florid schistosomiasis in addition to hepatitis B cirrhosis.
Conclusion: The diagnosis of pulmonary arterial hypertension associated with schistosomiasis may be difficult. It is necessary to repeat the serological studies and, sometimes, to obtain a rectal biopsy. The treatment of pulmonary arterial hypertension associated with schistosomiasis is based on specific therapies and antiparasitic treatment.
