Idiopathic non-cirrhotic portal hypertension in a patient with Talaromyces marneffei infection: a case report

Abstract

BackgroundThe etiopathogenesis of idiopathic non-cirrhotic portal hypertension (INCPH) is so far poorly understood. Altered immunity, blood diseases, infections, congenital defects and drug exposure have been documented in a part of patients with INCPH owing to increased recognition of the disorder in patients with HIV, or various haematological disorders or autoimmune diseases. We aim to discuss the possible etiopathogenesis of INCPH.Case presentationWe reported that a patient with intestinal infection of T. Marneffei and hyper-IgE syndrome, a group of rare primary immunodeficiency disorders, was finally diagnosed with INCPH for gastroesophageal variceal bleeding. The diagnosis was mainly based on histopathological features. Transjugular intrahepatic portosystemic shunt was performed and there was no recurrence of melena during the six-month follow-up.ConclusionIn the context of immunodeficiency, INCPH may associated with intestinal infections. Thus, screening for enterogenic infection and immunological disorders in patients with unexplained portal hypertension is necessary.
