RESUMO
PURPOSE OF REVIEW: This article summarizes the diagnosis and treatment of coccidioidal meningitis (CM) and its complications. An overview of current and prospective pharmacologic treatment options and monitoring parameters is provided. A consensus has not been reached regarding universally accepted therapeutic serum levels for azoles because of insufficient evidence. We describe the preferred therapeutic drug level ranges that our institution uses to monitor azole therapy. RECENT FINDINGS: Ho et al. described the preparation and administration of intrathecally delivered amphotericin B deoxycholate. Thompson et al. described possible benefits of controversial adjuvant corticosteroid therapy for secondary prevention of vasculitic infarction secondary to CM. CM was universally fatal until the advent of intrathecal amphotericin B deoxycholate therapy, the introduction of which changed the natural history of the disease in much the same way as penicillin changed the natural history of bacterial meningitis. Although there was still significant morbidity, survival rates drastically increased to approximately 70%. The introduction of azole therapy has decreased the side effects and burden of treatment but without a significant change in CM-related mortality and morbidity compared with the use of intrathecal amphotericin B deoxycholate therapy.

Coccidioidal meningitis (CM) is a devastating complication of coccidioidomycosis. Since the late 1950s, intrathecal (IT) amphotericin B deoxycholate (AmBd) has been successfully used to treat and often cure this disease, reducing mortality rates from 100% to approximately 30%. The introduction of azoles further revolutionized the treatment of coccidioidal infections. However, IT AmBd remains the only known curative option in the management of CM. While the use of IT AmBd is well described in many articles, few discuss the actual methods behind preparation, titration, and dosing strategies utilized. The practitioners at Kern Medical (Bakersfield, California) have >60 years of experience in the utilization of IT AmBd and the treatment of CM. This article describes the practice experience in the treatment of CM, preparation of IT AmBd, and the different dosing strategies used in regard to route of administration (ie, cisternal, lumbar, ventricular).
