Itraconazole treatment of coccidioidomycosis. NAIAD Mycoses Study Group.

PURPOSE: The purpose of this study was to assess the tolerance and efficacy of itraconazole in the treatment of coccidioidomycosis. PATIENTS AND METHODS: Fifty-one patients with nonmeningeal coccidioidomycosis were considered for treatment with intraconazole. Forty-nine patients who met study criteria were treated with itraconazole given orally in doses of 100 to 400 mg/day for periods up to 39 months. Of these patients, 12 had osteoarticular disease, 23 had chronic pulmonary disease, and 14 had skin or soft tissue disease. Clinical response was evaluated using a scoring system accounting for lesion number and size, symptoms, culture, and serologic titer. Remission was defined as reduction of the pretreatment score by 50% or more. RESULTS: Patients with osteoarticular, chronic pulmonary, and soft tissue disease improved at similar rates. Because two patients had no scoring assessment for efficacy, they were considered inassessable for efficacy. Forty-seven patients are evaluable. Of these patients, 44 have completed therapy, and three are still receiving itraconazole. Of the 44 patients no longer receiving therapy, 25 (57%) achieved remission. Of the 25 patients achieving remission, four later experienced a relapse. Therapy failed in 19 patients (43%). Of these cases, 16 (36%) were clinical failures and three (7%) developed drug intolerance that precluded continuation of treatment. Evaluation of culture conversions was of limited value in the osteoarticular patients, fewer than half of whom had follow-up biopsies. However, culture conversions were a useful index of response in patients with chronic pulmonary disease. During the course of treatment, serologic titers declined in the two groups with extrapulmonary disease, but not in patients with pulmonary coccidioidomycosis. Possible toxicities were generally mild. CONCLUSION: Itraconazole appears efficacious and very well tolerated in patients with coccidioidomycosis.

Itraconazole therapy for blastomycosis and histoplasmosis. NIAID Mycoses Study Group.

OBJECTIVE: To assess the efficacy and toxicity of orally administered itraconazole in the treatment of nonmeningeal, nonlife-threatening forms of blastomycosis and histoplasmosis. DESIGN: Prospective, nonrandomized, open trial. SETTING: Multicenter trial at 14 university referral centers. PATIENTS: Eighty-five patients with culture or histopathologic evidence of blastomycosis (48 patients) or histoplasmosis (37 patients). Patients receiving other systemic antifungal therapy were excluded. INTERVENTIONS: Itraconazole was administered orally at doses of 200 to 400 mg/d. Patients in whom treatment was considered a success were treated for a median duration of 6.2 months (blastomycosis) and 9.0 months (histoplasmosis). Disease activity was assessed at baseline; drug efficacy and toxicity were evaluated at monthly intervals during therapy, and efficacy was evaluated at regular follow-up visits after completion of therapy. The median duration of posttreatment evaluation for successfully treated patients was 11.9 months (blastomycosis) and 12.1 months (histoplasmosis). MEASUREMENTS AND MAIN RESULTS: Among the 48 patients with blastomycosis, success was documented in 43 (90%). The success rate for patients treated for more than 2 months was 95% (38 of 40). Among the 37 patients with histoplasmosis, success was documented in 30 (81%). The success rate for patients treated for more than 2 months was 86% (30 of 35). All patients with histoplasmosis in whom treatment failed had chronic cavitary pulmonary disease. Toxicity was minor; only 25 (29%) patients experienced any side effects, and itraconazole toxicity necessitated stopping therapy in only 1 patient. CONCLUSIONS: Itraconazole is a highly effective therapy for nonmeningeal, nonlife-threatening blastomycosis and histoplasmosis. The drug is associated with minimal toxicity.

Treatment of sporotrichosis with itraconazole. NIAID Mycoses Study Group.

PURPOSE: To describe the clinical presentation and outcomes of treatment with itraconazole in patients with sporotrichosis. METHODS: A culture for Sporothrix schenckii or compatible histopathology was required for inclusion in the study. Patients with both cutaneous and systemic sporotrichosis were treated. Patients received from 100 to 600 mg of itraconazole daily for 3 to 18 months. Patients were classified as responders or nonresponders. Responders were further classified as remaining on treatment, relapsed, or free of disease. Nonresponders included patients who failed to respond or progressed during treatment with itraconazole. RESULTS: Twenty-seven patients (mean age: 53 years) were treated with 30 courses of itraconazole. Diabetes mellitus and alcoholism were present in eight and seven patients, respectively. Sites of involvement included lymphocutaneous alone in 9 patients, articular/osseous in 15 (multifocal in 3), and lung in 3. Prior therapy was unsuccessful in 11 patients. Among the 30 courses, there were 25 responders and 5 nonresponders. All 5 nonresponders received at least 200 mg daily of itraconazole for durations that ranged from 6 to 18 months. Of the 25 responders, 7 relapsed 1 to 7 months after treatment durations of 6 to 18 months. Of the 7 who relapsed, 2 are responding to a second course. One responder was lost to follow-up after 10 months of treatment with itraconazole. Of the remaining 17 responders, 3 remain on treatment, and 14 are free of disease over follow-up durations of 6 to 42 months (mean: 17.6 months). Itraconazole was well tolerated with few side effects noted. CONCLUSIONS: These results document the efficacy of itraconazole in the treatment of cutaneous and systemic sporotrichosis.

NIAID Mycoses Study Group Multicenter Trial of Oral Itraconazole Therapy for Invasive Aspergillosis.

BACKGROUND: Invasive aspergillosis is the most common invasive mould infection and a major cause of mortality in immunocompromised patients. Response to amphotericin B, the only antifungal agent licensed in the United States for the treatment of aspergillosis, is suboptimal. METHODS: A multicenter open study with strict entry criteria for invasive aspergillosis evaluated oral itraconazole (600 mg/d for 4 days followed by 400 mg/d) in patients with various underlying conditions. Response was based on clinical and radiologic criteria plus microbiology, histopathology, and autopsy data. Responses were categorized as complete, partial, or stable. Failure was categorized as an itraconazole failure or overall failure. RESULTS: Our study population consisted of 76 evaluable patients. Therapy duration varied from 0.3 to 97 weeks (median 46). At the end of treatment, 30 (39%) patients had a complete or partial response, and 3 (4%) had a stable response, and in 20 patients (26%), the protocol therapy was discontinued early (at 0.6 to 54.3 weeks) because of a worsening clinical course or death due to aspergillosis (itraconazole failure). Twenty-three (30%) patients withdrew for other reasons including possible toxicity (7%) and death due to another cause but without resolution of aspergillosis (20%). Itraconazole failure rates varied widely according to site of disease and underlying disease group: 14% for pulmonary and tracheobronchial disease, 50% for sinus disease, 63% for central nervous system disease, and 44% for other sites; 7% in solid organ transplant, 29% in allogeneic bone marrow transplant patients, and 14% in those with prolonged granulocytopenia (median 19 days), 44% in AIDS patients, and 32% in other host groups. The relapse rates among those who completed therapy and those who discontinued early for possible toxicity were 12% and 40%, respectively; all were still immunosuppressed. CONCLUSION: Oral itraconazole is a useful alternative therapy for invasive aspergillosis with response rates apparently comparable to amphotericin B. Relapse in immunocompromised patients may be a problem. Controlled trials are necessary to fully assess the role of itraconazole in the treatment of invasive aspergillosis.

Treatment of histoplasmosis with fluconazole in patients with acquired immunodeficiency syndrome. National Institute of Allergy and Infectious Diseases Acquired Immunodeficiency Syndrome Clinical Trials Group and Mycoses Study Group.

PURPOSE: This study assesses the efficacy and safety of fluconazole therapy in patients with acquired immunodeficiency syndrome (AIDS) and mild to moderately severe manifestations of disseminated histoplasmosis. PATIENTS AND METHODS: This was a multicenter, open-label, nonrandomized prospective trial. All patients had AIDS and disseminated histoplasmosis. Patients were treated with 1,200 mg of fluconazole given by mouth once on the first day, then 600 mg once daily for 8 weeks, and those patients who improved clinically were then assigned fluconazole maintenance therapy 200 mg once daily for at least 1 year. Interim analysis revealed a high failure rate (10 of 20, 50%), causing revision of the protocol to increase the fluconazole dose to 1,600 mg given once on the first day, then 800 mg once daily, and the duration to 12 weeks for induction therapy and then 400 mg daily for 1 year for maintenance therapy. MEASUREMENTS AND MAIN RESULTS: Thirty-six of 49 patients (74%; 95% confidence interval [CI]: 59% to 85%) with mild to moderately severe clinical manifestations who entered into the revised study responded to 800 mg of fluconazole daily for 12 weeks as induction therapy. Of the seven patients who failed induction therapy because of progression of histoplasmosis, one died of the infection. Of 36 patients who entered into the maintenance phase of the study receiving 400 mg of fluconazole daily for 1 year, 11 (30.5%) relapsed, including one who died (2.8%). Two of the 49 patients (4.1%) were removed because of grade 4 adverse events, alkaline phosphatase elevation for one and aspartate aminotransferase elevation in the other. The relapse-free rate at 1 year was 53% (95% CI: 32% to 89%), prompting closure of the study. CONCLUSIONS: Fluconazole 800 mg daily is a safe and moderately effective induction therapy for mild or moderately severe disseminated histoplasmosis in patients with AIDS. On the basis of historic comparison, fluconazole 400 mg daily is less effective than itraconazole 200 to 400 mg daily or amphotericin B 50 mg given weekly as maintenance therapy to prevent relapse.
