Abstract
Background: Temporal arteritis is a large-vessel vasculitis mostly seen in the elderly. Amyloidosis may be secondary to a chronic inflammation of body organs. Here, we present the second case report of temporal arteritis complicated by amyloidosis that was successfully treated by tocilizumab.
Case presentation: A 64-year-old female presented complaining of fatigue, fever, and diarrhea accompanied by abdominal pain. One year before presentation, she was diagnosed with temporal arteritis. She was treated with 15 mg/day oral prednisone for the last 6 months, with partial remission, but persistence of the fatigue and an elevated erythrocyte sedimentation rate (ESR, 56 mm/h). Physical examination showed tenderness of both temporal arteries and a soft abdomen. Colon tissue biopsy showed amyloid depositions in the vessels and stroma that were positive for Congo red staining. Tocilizumab was started with 8 mg/kg intravenous, the diarrhea resolved, and the arthralgia improved within 1 month, with a decrease in the ESR to 8 mm/h, and a C-reactive protein (CRP) level of 0.98 mg/dl. Monthly tocilizumab therapy remains efficacious 12 months later and was stopped due to lack of tocilizumab from the hospital. No side effects of tocilizumab were registered.
Conclusion: Chronic inflammation may be complicated by amyloidosis in patients with rheumatic diseases and genetic predisposition. Therefore, it is important to screen for intestinal Amyloid A (AA) amyloidosis in individuals with gastrointestinal disorders complicated by rheumatic disorders. AA amyloidosis may be complicated by temporal arteritis and presented with gastrointestinal symptoms such as diarrhea.
Learning points: Amyloidosis is manifested by the deposition of insoluble protein aggregates in organs.Amyloid A (AA) amyloidosis occurs as a complication of chronic inflammation in patients with a genetic predisposition to rheumatic diseases.Temporal arteritis complicated with AA amyloidosis is extremely rare.
期刊介绍：
The European Journal of Case Reports in Internal Medicine is an official journal of the European Federation of Internal Medicine (EFIM), representing 35 national societies from 33 European countries. The Journal''s mission is to promote the best medical practice and innovation in the field of acute and general medicine. It also provides a forum for internal medicine doctors where they can share new approaches with the aim of improving diagnostic and clinical skills in this field. EJCRIM welcomes high-quality case reports describing unusual or complex cases that an internist may encounter in everyday practice. The cases should either demonstrate the appropriateness of a diagnostic/therapeutic approach, describe a new procedure or maneuver, or show unusual manifestations of a disease or unexpected reactions. The Journal only accepts and publishes those case reports whose learning points provide new insight and/or contribute to advancing medical knowledge both in terms of diagnostics and therapeutic approaches. Case reports of medical errors, therefore, are also welcome as long as they provide innovative measures on how to prevent them in the current practice (Instructive Errors). The Journal may also consider brief and reasoned reports on issues relevant to the practice of Internal Medicine, as well as Abstracts submitted to the scientific meetings of acknowledged medical societies.
