An early suspicion of rifabutin induced uveitis could also prevent invasive ocular procedures like aqueous sampling and a detailed drug history should be elicited in unexplained uveitis [15]. In some cases, hy-popyon and severe vitritis with snowballs opac-ities can be present (16). Uveitis was initially thought to be a rare, dose-limited complication of rifabutin therapy. So the hypopyon anterior uveitis, often unilateral, was a characteristic finding of rifabutin induced uveitis. uveitis) is recommended when rifabutin is coadministered with voriconazole. In an early dose-ranging tolerance study, uveitis was associated with daily doses of 1200 mg or more. The purpose of this study is to report the case of an HIV+ patient with unilateral rifabutin induced intermediate uveitis after 4 months of treatment with low dose rifabutin (150 mg daily) in combination with ritonavir and fluconazole.

In general, the path­ogenesis of drug-induced inflammation is not well understood. The rifabutin was stopped two months after the initiation and the uveitis resolved with topical corticosteroids. 1997 Apr;28(4):321-4. DESIGN: Retrospective observational study. 88,89 Rifabutin-induced uveitis may mimic infectious endophthalmitis, especially when a hypopyon is present; therefore, prompt evaluation is necessary. It’s a derivative of rifampin, used in immunocompromised patients, and it was characterized by hypopyon development. Saran and associates described the clinical features of seven patients with HIV/AIDS who received between 300 to 600 mg of rifabutin daily … The risk of rifabutin-associated uveitis may be increased in patients receiving concurrent therapy with clarithromycin or … 1996 Aug 8;335(6):377-83. doi: 10.1056/NEJM199608083350602.

Rifabutin is used to treat and prevent disseminated Mycobacterium avium-complex infection. Rifabutin is prescribed frequently for the prophylaxis and treatment of MAC infection, especially in patients with HIV. This study describes the clinical features and analyses the factors associated with rifabutin induced uveitis. Abstract Rifabutin is a semi-synthetic antimycobacterial agent mainly used in the treatment of Mycobacterium avium-complex (MAC) in AIDS patients. Intermediate uveitis is a relatively rare manifestation of Rifabutin induced uveitis. Indirectly induced uveitis can occur when a drug (alone or in combination with tissue or serum proteins) stimulates the immune system to form antidrug antibodies.41, 72, 73 If these antibodies result in immune complex deposition in uveal tissues, uveitis can be produced. Data sources: Rifabutin-induced uveitis occurs rarely when the drug is used as sole antimycobacterial therapy at the usual prophylactic dosage (i.e., 300 mg daily) for the prevention of M. avium complex (MAC) infections in patients with advanced HIV infection, even in combination with macrolide antibiotics or … Uveitis Associated with Rifabutin Therapy . Rifabutin-induced anterior uveitis has been reported previously. In an open-label, randomized trial comparing 2 regimens for the treatment of Mycobacterium avium complex bacteremia in patients with AIDS, the rate of uveitis was high (24/63 patients) in the arm receiving 600 mg of rifabutin in combination with ethambutol and clarithromycin. Rifabutin is a semi-synthetic antimycobacterial agent mainly used in the treatment of Mycobacterium avium-complex (MAC) in AIDS patients. 2020 Sep;68(9):1787-1798. doi: 10.4103/ijo.IJO_1248_20.

The authors review reports of drug-associated uveitis, applying the seven criteria and examining possible mechanisms. Proc Am Thorac Soc. Note the typical history and important findings of a constricted slightly irregular pupil with ciliary flush (i.e. Moorthy RS, Moorthy MS, Cunningham ET. Our findings support the observation that prophylactic doses of rifabutin, combined with clarithromycin, fluconazole or other agents which can increase rifabutin levels, can induce uveitis in patients with AIDS. If uveitis occurs, temporarily interrupt rifabutin therapy and obtain ophthalmic evaluation. A brief review of uveitis including its classification, causes, symptoms and signs is presented along with a review of systemic medications associated with uveitis. Revue des Maladies Respiratoires 21: 1004-1005, No. Uveitis associated with rifabutin and macrolide therapy for Mycobacterium avium intracellulare infection in AIDS patients. Although most cases of uveitis are due to autoimmune disorders or infections, medications are recognized as an increasingly important cause of uveitis. Most of our understanding of rifabutin-induced uveitis comes from cases series reported in the early- to mid-1990s … Clinical experience with rifabutin in the treatment of mycobacterial infections. 27 Indian J Ophthalmol. OBJECTIVE: Uveitis has been increasingly recognised as a side effect of rifabutin regimens in the prophylaxis and treatment of Mycobacterium avium intracellulare (MAI) infection. Rifabutin associated uveitis has been described in AIDS patients and is identified as a dose-dependent, idiosyncratic side effect [7]. Rifabutin is being prescribed increasingly for the treatment and prophylaxis of Mycobacterium avium complex (MAC) infection in the HIV-infected population. Clin Infect Dis. HHS Intermediate uveitis is a relatively rare manifestation of Rifabutin induced uveitis. Introduction Disodium Pamidronate, a Calcium regulating agent, was described by Macarol and Frauenfelder [1] and other authors [2-5] to induce ocular inflammation. Uveitis was rare when this drug was used as a single agent at 300 mg/day, or in combination with fluconazole and/or macrolides (e.g., clarithromycin). The purpose of this study is to report the case of an HIV+ patient with unilateral rifabutin induced intermediate uveitis after 4 months of treatment with low dose rifabutin (150 mg daily) in combination with ritonavir and fluconazole. COVID-19 is an emerging, rapidly evolving situation. Topical ocular medications such as beta-blockers and corticosteroids as well as other topical ocular medications have been associated with uveitis.
