VIEKIRA PAK (ritonavir-boosted paritaprevir/ombitasvir and dasabuvir) is an approved treatment for compensated patients with genotype 1 (GT1) chronic hepatitis C virus (HCV) infection. This oral regimen has minimal adverse effects and is well tolerated. Cure rates are 97% in patients infected with HCV GT 1a and 99% in those with HCV GT 1b. We report the first case of life-threatening allergic pneumonitis associated with VIEKIRA PAK. This unexpected serious adverse event occurred in a 68-year-old Chinese female with genotype 1b chronic hepatitis C and Child-Pugh A cirrhosis. One week into treatment with VIEKIRA PAK without ribavirin, she was admitted to hospital with respiratory distress and acute kidney injury requiring intensive care input. She was initially diagnosed with community acquired pneumonia and improved promptly with intravenous antibiotics and supported care. No bacterial or viral pathogens were cultured. Following complete recovery, she recommenced VIEKIRA PAK but represented 5 days later with more rapidly progressive respiratory failure, requiring intubation and ventilation, inotropic support, and haemodialysis. The final diagnosis was drug induced pneumonitis.

BACKGROUND: Scleromyxedema, also referred to as the Arndt-Gottron (S-AG) syndrome or the systemic form of Lichen myxedematosus (LM), is a cutaneous mucinosis with a chronic course and high lethality from systemic involvement of other organs and systems. Interesting in several aspects is the association between scleromyxedema and viral hepatitis about: 1) hepatitis virus infection as a possible etiological factor for the development of scleromyxedema, 2) antiretroviral therapy for the treatment of hepatitis as a method of reversing scleromyxedema and 3) antiviral drugs as inducers of scleromyxedema. CASE REPORT: We present a 53-year old patient who for nine months had been on tenofovir disoproxil 245 mg (0-0-1) therapy for chronic hepatitis B. Three months after the start of antiviral therapy (i.e. for a period of 6 months), the patient observed swelling, itching and hardening of the skin on the face, ears and hands, which subsequently spread throughout the trunk. Subsequent histological study of a skin biopsy revealed changes of scleromyxedema at an advanced stage, though immunoelectrophoresis of serum and urine excluded the presence of paraproteinaemia or para proteinuria. Systemic antihistamine and topical corticosteroid therapy were instituted. Bone involvement with possible plasmacytoma was excluded, and a myelogram showed evidence of an erythroblastic reaction of bone marrow. CONCLUSION: We believe that drug-induced scleromyxedema is a rare but possible phenomenon. We describe the first case of tenofovir-induced scleromyxedema within the framework of chronic hepatitis B treatment.
