We report the case of a rifabutin-induced cystoid macular oedema (CMO) in an immunocompetent patient with pulmonary MAC infection. matory opacities of the vitreous in rifabutin-associated uveitis. Anterior segment manifestations of human immunodeficiency virus/acquired immune deficiency syndrome.  |  Mycobacterium avium complex infection, rifabutin, and uveitis--is there a connection? Rifabutin-associated uveitis has been reported frequently in AIDS patients and more rarely in immunocompetent patients. Drug-induced uveitis. We will report a case of uveitis induced by the same substance in a patient treated for hypercalcemia secondary to multiple myeloma. Ophthalmic Surg Lasers. Topical ocular medications such as beta-blockers and corticosteroids as well as other topical ocular medications have been associated with uveitis. Uveitis occurred in patients given 1050 to 2400 mg/day; symptoms abated when treatment was discontinued. Risk factors for developing rifabutin associated-uveitis include a high dose of rifabutin reaching 600 mg orally daily, low body weight, and concomitant use of other drugs, such as macrolides or ritonavir. PURPOSE: To describe an ocular complication of rifabutin therapy in the treatment of Mycobacterium avium complex (MAC) infection in the absence of HIV infection or AIDS. In general, the pathogenesis of drug-induced inflammation is not well understood. Clipboard, Search History, and several other advanced features are temporarily unavailable. We report the case of a rifabutin-induced cystoid macular oedema (CMO) in an immunocompetent patient with pulmonary MAC infection. Early diagnosis and is important and reduction or discontinuance of the rifabutin as well as anti-inflammatory therapy need to be implemented when a patient develops this condition. Other systemic medications may cause uveitis. USA.gov. Data synthesis: Because this toxicity appeared to be dose-related, lower dosages (300-600 mg/d) of rifabutin were selected for study in subsequent clinical trials. Cidofovir (intravenous) 2. Of these patients, 158 (72%) tolerated rifabutin during treatment, but 47 (21%) and 16 (7%) experienced mild and severe rifabutin-related ARs (including neutropenia, severe hepatitis and uveitis), respectively, and needed to discontinue rifabutin. severe acute anterior uveitis, spillover vitreous cells may occur. Symptoms of acute uveitis may present 2 weeks to more than 7 months following initiation of therapy. Rifabutin-associated uveitis is only rarely seen in children. A minority of patients treated with higher doses (300 to >450 mg/day) can develop uveitis 2 weeks to 14 months after treatment initiation. To review rifabutin-associated uveitis and discuss the mechanism and potential role of drug interactions with clarithromycin and fluconazole in contributing to this adverse event. In 1993, the Public Health Service Task Force recommended use of Mycobutin * (rifabutin) at a daily dose of 300 mg for prophylaxis for disseminated Mycobacterium avium complex (MAC) infection in patients with human immunodeficiency virus (HIV) infection and less than 100 CD4+ T-lymphocytes/uL (1). [Uveitis associated with rifabutin treatment. Uveitis is a rare, dose-related toxicity of this therapy. Miotics 3. In an early dose-ranging tolerance study, uveitis was associated with daily doses of 1200 mg or more. Results: Risk factors for developing rifabutin associated-uveitis include a high dose of rifabutin reaching 600 mg orally daily, low body weight, and concomitant use of other drugs, such as macrolides or ritonavir. In most cases, uveitis resolved within 1-2 months following discontinuation of rifabutin with or without administration of topical corticosteroids. Rifabutin induced uveitis is typically - as presented in patient 1 - unilateral, non granulomatous with a mild to moderate cellular reaction of the anterior segment and the vitreous.

Uveitis, which unsurprisingly means inflammation of the uveal tract. We will report a case of uveitis induced by the same substance in a patient treated for hypercalcemia secondary to multiple myeloma. 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. Rifabutin has been associated not only with a characteristic hypopyon anterior uveitis, but also with other forms of uveitis such as intermediate uveitis, panuveitis, and retinal vasculitis, which have been recently reported. If uveitis occurs, temporarily interrupt rifabutin therapy and obtain ophthalmic evaluation. Data sources: Intermediate uveitis, panuveitis and retinal vasculitis have been reported with rifabutin. All articles and abstracts reporting uveitis potentially related to rifabutin were considered for inclusion.

However, clarithromycin and/or fluconazole can raise rifabutin levels (and consequently the risk for uveitis) due to shared hepatic metabolism by the same cytochrome P450 system. Uveitis is usually due to immune or infectious causes; however, certain systemic or local drugs may also precipitate intra­ocular inflammation. Clarithromycin inhibited rifabutin’s metabolism and doubled the blood level. 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. 2008 Sep-Oct;56(5):363-75. doi: 10.4103/0301-4738.42412.
