ABSTRACT
BACKGROUND: To report a case of coinfection of Toxoplasma gondii (Tg) and Epstein Barr Virus (EBV) in a diabetic patient with rheumatoid arthritis and immunosuppressive biological therapy. CASE PRESENTATION: A 70-year-old female with a history of rheumatoid arthritis on therapy with corticosteroids, methotrexate, and abatacept presented bilateral granulomatous panuveitis associated with retinal necrosis and macular involvement. A diagnostic vitrectomy detected Tg and EBV. Treatment with clindamycin, trimethoprim-sulfamethoxazole, and acyclovir was established, achieving improvement. CONCLUSIONS: Patients undergoing immunosuppressive therapy are at risk of developing opportunistic infections, often presenting with severe and atypical clinical manifestations. In such cases, multiplex polymerase chain reaction is an invaluable diagnostic tool that helps identify the specific pathogens involved. This enables healthcare professionals to make informed treatment decisions and provide targeted therapy for each identified pathogen.
ABSTRACT
Background. The syndrome of tubulointerstitial nephritis and uveitis (TINU) is a rare oculorenal condition, mainly seen in children and women. The underlying cause of this disease is unknown. Case Presentation. We report a 24-year-old male without any past medical history, diagnosed with bilateral uveitis and azotemia. Biopsy revealed tubulointerstitial nephritis, consistent with TINU syndrome. Fluorescein angiogram revealed peripheral retinal vasculitis. Discussion. TINU is a rare disorder that needs to be distinguished from sarcoidosis, Sjogren's disease, and tuberculosis. Treatment is indicated in patients with progressive renal insufficiency, consisting of steroid therapy. Most patients recover kidney function. Its early recognition is important to offer the best chance of organ preservation.
ABSTRACT
Purpose: To describe a case of leprosy presenting chronic anterior uveitis associated with other systemic lesions.Methods: Case report and systematic literature review.Results: We describe the case of a 65-year-old patient presenting clinical features of chronic uveitis and poor response to topical and intravitreal steroid treatment. Upon ocular examination, diffuse iris atrophy and macular edema were observed and laboratory tests for autoimmune and infectious diseases were within normal range. Physical examination revealed the presence of skin lesions on trunk and extremities, which were biopsied and identified as positive for leprosy.Conclusion: The case reported herein presented atypical characteristics of uveitis due to the involvement of the posterior segment of the eye. Leprosy diagnosis could be a challenge, a systematic approach is mandatory to achieve adequate treatment.
