Rifabutin is used to treat and prevent disseminated Mycobacterium avium-complex infection. 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 and macrolide therapy for Mycobacterium avium intracellulare infection in AIDS patients. the principal risk factor for rifabutin induced uveitis wasconcurrentclarithromycin therapy. Results:  |  The risk of rifabutin-associated uveitis may be increased in patients receiving concurrent therapy with clarithromycin or fluconazole because of drug interactions.

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. In some cases, hy-popyon and severe vitritis with snowballs opac-ities can be present (16).

We report the case of a rifabutin-induced cystoid macular oedema (CMO) in an immunocompetent patient with pulmonary MAC infection. Drug-induced uveitis is a relatively rare occurrence. Only systemically administered biphosphonates and, perhaps, topical metipranolol meet all seven criteria. Dosage and duration are significant risk factors for rifabutin-induced uveitis. Three patients on rifabutin therapy for MAC chest infection developed anterior uveitis with vitreous infiltrates. Rifabutin-induced uveitis with inflammatory vitreous infiltrate.

Symptoms of acute uveitis may present 2 weeks to more than 7 months following initiation of therapy. 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 was initially thought to be a rare, dose-limited complication of rifabutin therapy. Curr Opin Ophthalmol, 29(6):588-603, 01 Nov 2018 Cited by 3 articles | PMID: 30222658. Review.
