Abstract Central nervous system infection with Coccidioides spp. is fatal if untreated and complications occur even when therapy is directed by experienced clinicians. We convened a panel of clinicians experienced in the management of coccidioidal meningitis to summarize current controversies and provide consensus for the management of this difficult infection.
FDA Public Workshop Summary—Coccidioidomycosis (Valley Fever): Considerations for Development of Antifungal Drugs
Abstract Coccidioidomycosis is a fungal disease endemic to the southwestern United States, Mexico, and Central and South America. Prevalence rates are increasing steadily, and new endemic areas of Coccidioides are emerging. Standard treatment is often administered for months to decades, and intolerance to medications and treatment failures are common. No new treatments for coccidioidomycosis have been approved in the United States in nearly 40 years. On 5 August 2020, the US Food and Drug Administration convened experts in coccidioidomycosis from academia, industry, patient groups, and other government agencies to discuss the disease landscape and strategies to facilitate product development for treatment of coccidioidomycosis. This article summarizes the key topics concerning drug development for coccidioidomycosis presented by speakers and panelists during the workshop, such as unmet need, trial designs, endpoints, incentives, research and development support, and collaborations to facilitate antifungal drug development.
Treatment for Early, Uncomplicated Coccidioidomycosis: What Is Success?
AbstractThe care of primary pulmonary coccidioidomycosis remains challenging. Such infections produce a variety of signs, symptoms, and serologic responses that cause morbidity in patients and concern in treating clinicians for the possibility of extrapulmonary dissemination. Illness may be due to ongoing fungal growth that produces acute inflammatory responses, resulting in tissue damage and necrosis, and for this, administering an antifungal drug may be of benefit. In contrast, convalescence may be prolonged by other immunologic reactions to infection, even after fungal replication has been arrested, and in those situations, antifungal therapy is unlikely to yield clinical improvement. In this presentation, we discuss what findings are clinical indicators of fungal growth and what other sequelae are not. Understanding these differences provides a rational management strategy for deciding when to continue, discontinue, or reinstitute antifungal treatments.
Oxygen Consumption Deficits in Patients With Residual Fatigue After Primary Coccidioidomycosis
Abstract Patients with coccidioidomycosis often report prolonged and debilitating fatigue after other evidence of infection has resolved. In this study, we quantify fatigue, muscle weakness, and impaired aerobic capacity in 5 such individuals. A closer examination of the cardiorespiratory system may contribute to a better understanding of underlying mechanisms and potential interventions.
Approach to Management of Coccidioidomycosis in Patients Receiving Inhibitors of Tumor Necrosis Factor-α
Abstract Inhibitors of tumor necrosis factor-α (TNFIs) have revolutionized the treatment for patients with a variety of inflammatory illnesses, including rheumatoid arthritis, psoriasis and psoriatic arthritis, ankylosing spondylitis, and other inflammatory diseases, and have improved the outcomes and quality of life for such patients. Endemic fungal infections, such as coccidioidomycosis, are observed to occur in persons who are treated with these agents and who live in the Coccidioides-endemic area with similar frequency as persons in the general, healthy public but with an increased likelihood of symptomatic infection and extrapulmonary dissemination. Because the control of coccidioidal infections requires the formation and maintenance of granuloma, it is not unexpected that TNFIs, which inhibit granuloma formation, seem to increase the risk of clinical disease. No guidelines exist to address the prevention and management of disease in patients whose treatment course with TNFIs is complicated by subclinical or clinical coccidioidal infection. Therefore, we reviewed the available medical literature and offer suggestions to the approach and treatment of patients with various forms of coccidioidomycosis before and during therapy with TNFIs.
Executive Summary: 2016 Infectious Diseases Society of America (IDSA) Clinical Practice Guideline for the Treatment of Coccidioidomycosis
Abstract It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. Infectious Diseases Society of America considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances. Coccidioidomycosis, also known as San Joaquin Valley fever, is a systemic infection endemic to parts of the southwestern United States and elsewhere in the Western Hemisphere. Residence in and recent travel to these areas are critical elements for the accurate recognition of patients who develop this infection. In this practice guideline, we have organized our recommendations to address actionable questions concerning the entire spectrum of clinical syndromes. These can range from initial pulmonary infection, which eventually resolves whether or not antifungal therapy is administered, to a variety of pulmonary and extrapulmonary complications. Additional recommendations address management of coccidioidomycosis occurring for special at-risk populations. Finally, preemptive management strategies are outlined in certain at-risk populations and after unintentional laboratory exposure.
