Portal Hypertension Due to Hepatoportal Sclerosis in an HIV-Positive Patient Secondary to Didanosine Use

Noncirrhotic portal hypertension (NCPH) has recently been found in human immunodeficiency virus (HIV) -infected patients taking didanosine. Here, we describe an HIV-infected patient with portal hypertension due to hepatoportal sclerosis who presented with hematemesis at the emergency department (ED). CT angiography of the abdomen and pelvis with and without contrast revealed a diminutive portal vein with corresponding massive lower esophageal varices and superior mesenteric vein to the right gonadal vein varices. Esophagogastroduodenoscopy (EGD) revealed grade II varices were found in the lower third of the esophagus, for which the patient???s symptoms improved with emergency endoscopic band ligation, octreotide and didanosine discontinuation. Our case demonstrates a rare complication that can occur with continued didanosine use in an HIV-positive patient. We highlight the need for a standard diagnostic upper gastrointestinal endoscopy to screen for portal hypertension and high-risk esophageal varices in patients with long-term didanosine use as seen in our patient.
