Priming the Immune Pump: Antibiotic-Induced DRESS-Associated Hepatic Injury Following Infection With SARS-CoV-2
AMERICAN JOURNAL OF GASTROENTEROLOGY(2021)
摘要
Introduction: Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a systemic adverse drug reaction that manifests as rash and fever with visceral involvement, most commonly hepatic and renal. It typically develops within 2-6 weeks of drug exposure or weeks after cessation. An increased incidence of DRESS syndrome in the context of recent SARS-CoV-2 infection has been identified. This is postulated to be a result of an augmented antiviral immune response upon ingestion of an offending agent. Here we present a case of DRESS syndrome following recent SARS-CoV-2 infection. Case Description/Methods: A 19-year-old female with a history of outpatient SARS-CoV-2 infection one month prior presented with a two-week history of nausea, vomiting, and jaundice after treatment with azithromycin and nitrofurantoin for upper respiratory and urinary tract infections. She was febrile to a maximum temperature of 38.8ºC. Physical exam revealed normal vital signs, scleral icterus, perioral and periorbital edema, and a diffuse pruritic reticular rash with areas of confluence and macules on >50% of body surface area. Transaminases were elevated (AST 873 IU/L; ALT 1078 IU/L). Leukocytosis (31,112/mL) with eosinophilia and atypical lymphocytes was observed. Serologic testing for viral hepatitis A, B, and C was negative. Mononucleosis screen was negative. Screening for other metabolic or autoimmune etiologies of liver injury was negative. Liver biopsy on hospital day 4 showed active hepatitis with evidence suggestive of a drug reaction. Skin biopsy from the left thigh on hospital day 5 showed perivascular lymphohistiocytic infiltrate with vacuolar epidermal changes, focal spongiosis, and occasional eosinophils consistent with DRESS syndrome. She was treated with prednisone with significant improvement. Full resolution of the elevated liver enzymes and rash was observed within two weeks. Discussion: There have been several recent reports of DRESS syndrome after SARS-CoV-2 infection. It is postulated that patients with recent SARS-CoV-2 infection are at higher risk of idiosyncratic drug-induced liver injury due to the dysregulation of innate and adaptive immune responses following infection. Several medications have been implicated in the development of DRESS syndrome including azithromycin and nitrofurantoin. This case illustrates a rare complication of SARS-CoV-2 infection and highlights the importance of further investigating the immunomodulatory effects of the virus.Figure 1.: Diffuse pruritic reticular rash consistent with DRESS syndrome on back.
