Abstract
AIDS-related disseminated histoplasmosis (DH) can cause septic shock and multiorgan dysfunction with mortality rates of up to 80%. A 41-year-old male presented with fever, fatigue, weight loss, disseminated skin lesions, low urine output, and mental confusion. Three weeks before admission, the patient was diagnosed with HIV infection, but antiretroviral therapy (ART) was not initiated. On day 1 of admission, sepsis with multiorgan dysfunction (acute renal failure, metabolic acidosis, hepatic failure, and coagulopathy) was identified. A chest computed tomography showed unspecific findings. Yeasts suggestive of Histoplasma spp. were observed in a routine peripheral blood smear. On day 2, the patient was transferred to the ICU, where his clinical condition progressed with reduced level of consciousness, hyperferritinemia, and refractory septic shock, requiring high doses of vasopressors, corticosteroids, mechanical ventilation, and hemodialysis. Amphotericin B deoxycholate was initiated. On day 3, yeasts suggestive of Histoplasma spp. were observed in the bone marrow. On day 10, ART was initiated. On day 28, samples of peripheral blood and bone marrow cultures revealed Histoplasma spp. The patient stayed in the ICU for 32 days, completing three weeks of intravenous antifungal therapy. After progressive clinical and laboratory improvement, the patient was discharged from the hospital on oral itraconazole, trimethoprim-sulfamethoxazole, and ART. This case highlights the inclusion of DH in the differential diagnosis of patients with advanced HIV disease, septic shock and multiorgan dysfunction but without respiratory failure. In addition, it provides early in-hospital diagnosis and treatment and comprehensive management in the ICU as determining factors for a good outcome.

Abstract
Coccidioidomycosis is an endemic fungal infection that is reported in up to 20,000 persons per year and has an economic impact close to $1.5 billion. Natural infection virtually always confers protection from future exposure, and this suggests that a preventative vaccine strategy is likely to succeed. We here review progress toward that objective. There has been ongoing research to discover a coccidioidal vaccine over the past seven decades, including one phase III clinical trial, but for reasons of either efficacy or feasibility, a safe and effective vaccine has not yet been developed. This review first summarizes the past research to develop a coccidioidal vaccine. It then details the evidence that supports a live, gene-deletion vaccine candidate as suitable for further development as both a veterinary and a human clinical product. Finally, a plausible vaccine development plan is described which would be applicable to this vaccine candidate and also useful to other future candidates. The public health and economic impact of coccidioidomycosis fully justifies a public private partnership for vaccine development, and the development of a vaccine for this orphan disease will likely require some degree of public funding.
