ABSTRACT
Acyclovir is a remarkably safe drug with potent antiviral effect against herpes virus. The two most serious adverse effects are neurotoxicity and nephrotoxicity. We here report the case of a 64-year old woman with acyclovir induced acute interstitial nephritis. She developed non-oliguric acute renal failure following the administration of oral acyclovir(800mg five times per day) to treat herpes zoster of left 2nd and 3rd thoracic nerves. We documented a normal serum creatinine level just before exposure to the drug. On admission, serum creatinine level was 2.4 mg/dL(baseline level; 0.8mg/dL). Percutaneous renal biopsy revealed interstitial infiltration of lymphocyte and eosinophil with interstitial edema, but there was no crystal formation in the tubules or collecting ducts. After withdrawal of the acyclovir, renal function returned to normal within 1 week.

Although gastrointestinal manifestations are very common in patients with Henoch-Sch nlein purpura, protein losing enteropathy is a rare complication. We here report a case of protein losing enteropathy in a patient with Henoch-Sch nlein purpura. A 52-year old woman presented with lower abdominal pain, purpura and edema on lower extremity. Serum albumin was 1.9g/dL and 24 hour urine protein was 4.7g/ day. Skin and kidney biopsy revealed leukocytoclastic vasculitis and mesangial proliferative glomerulonephritis consistent with Henoch-Sch nlein purpura, respectively. Colonoscopy showed diffuse mucosal erosion at right colon. 99mTc-human serum albumin scintigraphy and fecal alpha-1-antitrypsin clearance confirmed protein losing enteropathy. The protein losing enteropathy improved with steroid treatment.
