Dinitrochlorobenzene responsivity: difference between patients with severe pulmonary coccidioidomycosis and patients with disseminated coccidioidomycosis.

Immunologic responses in 15 patients with severe pulmonary coccidioidomycosis and in 50 patients with disseminated coccidioidomycosis were measured by determination of complement-fixing (CF) antibody titers to coccidioidin in serum, coccidioidin (1:100) skin tests, and sensitization to dinitrochlorobenzene. Among the patients with desseminated coccidioidomycosis, the nine with CF antibody titers of less than or equal to 1:8 had normal responses to dinitrochlorobenzene, but the 41 with titers of greater than or equal to 1:16 had responses that were significantly lower than those of controls (P less than 0.001). In contrast, all patients with severe pulmonary coccidioidomycosis had CF antibody titers of greater than or equal to 1:16 and had responses to dinitrochlorobenzene that were greater (but not significantly greater) than those of controls. Among subjected with antibody titers of greater than or equal to 1:16, responsiveness to coccidioidin was found in 27% of those with severe pulmonary disease and in 39% of those with disseminated disease. Thus impaired responsivity to dinitrochlorobenzene in coccidioidomycosis is restricted to patients who have disseminated illness and high titers of CF antibody and is separable from lack of responsiveness to coccidioidin.

Agar-gel precipitin-inhibition test for coccidioidomycosis. I. Preliminary evaluation of the complement-fixation and agar-gel precipitin tests in the serodiagnosis of human coccidioidomycosis.

The agar-gel precipitin-inhibition serological test for coccidioidomycosis was a more sensitive indicator of Coccidioides immitis antibodies than the tube precipitin, the agar-gel immunodiffusion, in the complement-fixation tests in assaying monkey sera, whether these sera were from prechallenge-vaccinated or postchallenged animals. When applying this technique to the assay of human sera, an analogous finding generally persisted. However, some human sera were positive by the complement-fixation test and negative by the agar-gel precipitin-inhibition test. These sera were diffused in agar-gel against various coccidioidin complement-fixation, tube precipitin, and agar-gel precipitin-inhibition test antigens with essentially negative results.

Coccidioidomycosis during human immunodeficiency virus infection: results of a prospective study in a coccidioidal endemic area.

PURPOSE: To determine the incidence of active coccidioidomycosis among subjects infected with the human immunodeficiency virus (HIV) living in an area endemic for coccidioidomycosis and to identify factors associated with the development of active coccidioidomycosis in these patients. PATIENTS AND METHODS: This was a prospective cohort analysis of HIV-infected subjects living in an area endemic for coccidioidomycosis in Arizona. On entry and at approximately 4-month intervals, subjects were interviewed and examined, and had spherulin skin testing and CD4 lymphocyte counts performed along with other tests. During each interval, it was determined whether the subject had developed active coccidioidomycosis according to established criteria. RESULTS: One hundred seventy subjects entered the study. Median follow-up was 11.3 months (range: 0 to 44 months). Thirteen subjects developed active coccidioidomycosis, with an estimated cumulative incidence of 24.6% by 41 months (95% confidence limits 8.2% and 41.1%). Risk factors associated with the development of active coccidioidomycosis in the cohort were a CD4 lymphocyte count of less than 0.250 x 10(9)/L and a diagnosis of acquired immunodeficiency syndrome. Factors associated with prior coccidioidal infection, including a positive spherulin skin test, length of residence in the endemic area for more than 25 months, and a prior history of coccidioidomycosis, were not associated with the development of active infection. CONCLUSION: Active coccidioidomycosis among individuals infected with HIV is common in the coccidioidal endemic area. Immunodeficiency appears to be the major risk factor for the development of disease. Evidence of prior coccidioidomycosis, including a positive spherulin skin test, does not appear to predict the development of active infection.

Increased risk of coccidioidomycosis in patients treated with tumor necrosis factor alpha antagonists.

OBJECTIVE: To describe a group of patients who were treated with tumor necrosis factor alpha (TNF alpha) antagonists and who developed coccidioidomycosis, and to test the hypothesis that patients with inflammatory arthritis receiving TNF alpha antagonist therapy are at higher risk for developing symptomatic coccidioidomycosis. METHODS: Cases of coccidioidomycosis were identified and reviewed from among patients receiving TNF alpha antagonist therapy from May 1998 through February 2003 in 5 practices within the areas endemic for coccidioidomycosis (Arizona, California, and Nevada). In addition, the relative risk of developing symptomatic coccidioidomycosis was calculated in patients with inflammatory arthritis who were receiving treatment with infliximab, in comparison with patients with inflammatory arthritis who were not receiving infliximab, from January 2000 to February 2003 in a single medical center. RESULTS: Thirteen cases of documented coccidioidomycosis were associated with TNF alpha antagonist therapy. Twelve cases were associated with the use of infliximab and 1 case with etanercept. Among the cohort of patients from a single medical center, 7 of the 247 patients receiving infliximab and 4 of the 738 patients receiving other therapies developed symptomatic coccidioidomycosis (relative risk 5.23, 95% confidence interval 1.54-17.71; P < 0.01). CONCLUSION: Patients with inflammatory arthritis who are undergoing treatment with infliximab appear to be at higher risk for developing symptomatic coccidioidomycosis as compared with those not receiving infliximab.

Treatment of coccidioidomycosis with ketoconazole: an evaluation utilizing a new scoring system.

The evaluation of the response of patients with coccidioidomycosis to any therapeutic modality is a major challenge. A numerical scoring system was devised to quantitate separately the severity of disease on clinical presentation, the findings on chest film, bone scan, gallium scan, serology and skin test with coccidioidin and spherulin. The scoring system was used to evaluate the response to treatment with ketoconazole of seven patients with infiltrate pulmonary coccidioidomycosis; 20 patients with chronic cavitary coccidioidomycosis; and 40 patients with disseminated coccidioidomycosis. Dissemination included the soft tissue in 15, bone in 15, synovium in 11 and skin in 18. In all categories clinical severity scores improved dramatically. Radiographic scores showed similar improvement in cases of infiltrative pulmonary coccidioidomycosis but showed no change in cavitary coccidioidomycosis. Serology scores improved significantly (-2 or more) in one of seven infiltrative pulmonary cases, three of twenty chronic cavitary cases and twenty-three of forty disseminated cases. Among those with adequate mycology followup, cultures converted to negative in two of three infiltrative pulmonary coccidioidomycosis; seven of fourteen chronic cavitary coccidioidomycosis; and sixteen of twenty-two with disseminated disease. Unfortunately, when ketoconazole was discontinued or interrupted, symptoms recurred in four of twenty (20 percent) with chronic cavitary and ten of forty (25 percent) of disseminated cases. The disease in two patients progressed while on ketonconazole. One of those developed meningitis.

Coccidioidomycosis after renal transplantation in an endemic area.

Coccidioidomycosis is an endemic fungal infection of the desert southwestern United States of particular concern for immunosuppressed renal transplant recipients. The clinical course of coccidioidomycosis can be severe in immunosuppressed patients, with high rates of dissemination and mortality, and antifungal prophylaxis is routinely administered to high-risk patients. We sought to determine the impact of coccidioidomycosis on patients who received their renal transplant at our hospital in Phoenix, Arizona. A retrospective records review of the first 205 patients who received a renal transplant between June 1999 and December 2003 identified 6 patients (3%) who had contracted coccidioidomycosis after transplantation. All six cases occurred more than 6 months after transplantation. Two of these six patients had disseminated coccidioidomycosis. Two patients, one with pulmonary infection and one with disseminated infection, died. None of the six patients with coccidioidomycosis after transplantation had identified risk factors before transplantation. No high-risk patient who received targeted antifungal prophylaxis had a reactivation of coccidioidomycosis after transplantation. Treatment for acute rejection and induction with antithymocyte globulin did not appear to increase the risk of subsequent coccidioidomycosis.

Coccidioidomycosis of the male genital tract.

PURPOSE: Symptomatic genital tract infection is a rare manifestation of disseminated coccidioidomycosis. We characterized the clinical presentation, diagnosis, management and outcome in male patients with genitourinary coccidioidomycosis. MATERIALS AND METHODS: We reviewed all cases of genital tract coccidioidomycosis involving testes, epididymis or prostate at our institution between 1990 and 2000, and searched the medical literature for all reports since the first reported case in 1943. RESULTS: A total of 30 male patients with a median age of 58 years who had coccidioidomycosis of the genital tract were identified, including 6 at our institution. Four patients (13%) had a simultaneous pulmonary infection and 63% (19) had a remote history of primary pulmonary coccidioidomycosis. The most commonly involved genital tract sites were the epididymis in 18 cases, prostate in 14 and testes in 6. Patients with prostatitis presented with urinary obstruction, prostatic enlargement, tenderness and palpable nodules. Most patients with epididymal infection presented with scrotal swelling, tenderness and induration. All 30 patients (100%) had histopathological evidence of granulomatous inflammation with fungal spherules. Urine fungal cultures were positive in 19 cases (63%). A total of 12 patients received combined medical and surgical treatment, and 18 underwent surgical excision only. Most immunocompetent patients with isolated genital coccidioidomycosis did well with surgical resection alone. Six deaths occurred in patients with multifocal, extragenital, disseminated disease. CONCLUSIONS: Male genitourinary coccidioidomycosis is rare but it should be considered in the differential diagnosis of patients with exposure to the endemic area who present with prostatitis or epididymitis.

In vitro whole-blood analysis of cellular immunity in patients with active coccidioidomycosis by using the antigen preparation T27K.

Measurement of cellular immunity in human coccidioidomycosis has important diagnostic and prognostic implications. The coccidioidin skin test has been the standard for the measurement of this, but it is not available in the United States. We examined the utility of measuring surface expression of CD69 on T lymphocytes in whole blood incubated with the coccidioidal antigen preparation T27K as an alternative to the skin test. Seventy donors with active coccidioidomycosis were studied. The mean fluorescent intensity (MFI) of CD69 expression on CD3 lymphocytes in response to T27K was 28.61 +/- 1.77, significantly greater than the control response of 11.45 +/- 0.78 (P < 0.001). The MFI CD69 response to T27K above that for the control (MFI CD69 above control) was 6.35 +/- 2.18 for seven subjects with disseminated coccidioidomycosis who were studied within 5 months of diagnosis. This was significantly below the value of 20.17 +/- 3.17 for 18 subjects with pulmonary coccidioidomycosis studied within 5 months of diagnosis and the value of 19.58 +/- 2.91 for 27 subjects with disseminated coccidioidomycosis studied after 5 months of diagnosis (for both, P < 0.05). There was an inverse correlation between coccidioidal clinical score and MFI CD69 above control for all 34 subjects with disseminated coccidioidomycosis (r = 0.362; P = 0.036) but not for the 36 subjects with pulmonary disease (r < 0.001; P = 0.993). Among 30 subjects for whom data were available, there was a highly significant association between the MFI CD69 above control and the supernatant concentrations of gamma interferon, interleukin-2 (IL-2), and tumor necrosis factor alpha (for all, P < 0.001), but not for IL-4, IL-5, or IL-10. These data indicate that in vitro assessment of CD69 expression on T lymphocytes by using T27K may be a useful measure of cellular immune response among subjects with active coccidioidomycosis.

Miliary coccidioidomycosis in the immunocompetent.

BACKGROUND: Miliary coccidioidomycosis indicates hematogenous or lymphatic spread of Coccidioides immitis and is characterized by the development of multiple small granulomas throughout the lungs and other organs. Previous reports have suggested that this disorder occurs almost exclusively in immunocompromised patients, with most patients succumbing to progressive respiratory failure. In this article, we describe the largest series of immunocompetent patients with miliary coccidioidomycosis, define clinical characteristics, and outline important aspects of diagnosis and treatment. MATERIALS AND METHODS: We identified eight patients (five men and three women; age range, 23 to 65 years) with miliary coccidioidomycosis diagnosed at Kern Medical Center (located in an endemic area) from 1990 to 1997. Four of the patients were white, two were African American, and two were Hispanic. A miliary pattern was defined as the presence of discrete 2- to 10-mm lesions diffusely distributed throughout both lung fields, as shown on chest radiograph. Microscopic examination and culture of C immitis from sputum, tissue, or body fluid confirmed diagnosis. Patients with HIV were excluded. RESULTS: These patients constituted approximately 1% of those admitted to our institution for coccidioidomycosis from 1990 to 1997. Four patients had symptoms for < or = 1 week before admission (acute), and four had symptoms for between 5 and 12 weeks (chronic). Four patients demonstrated a miliary pattern on initial chest radiograph, and two of these patients received an initial diagnosis of miliary coccidioidomycosis. Five patients required mechanical ventilation. Arterial blood gas measurements revealed a mean PO(2) of 54.2 +/- 8. 6 mm Hg and a mean PCO(2) of 32.5 +/- 3.2 mm Hg. Five patients developed ARDS. Five patients had extrapulmonary involvement, with the meninges (n = 4) and skin (n = 4) being the most common sites. All patients were treated with fluconazole and/or amphotericin B. Three patients died; all had chronic involvement and received mechanical ventilation. CONCLUSION: We present eight immunocompetent patients with a lower mortality rate and better outcome than previously reported. In our series, miliary coccidioidomycosis manifested as either an acute respiratory illness or an advanced stage of a chronic illness occurring in the context of widespread dissemination. All who died had chronic involvement. Prompt recognition of miliary coccidioidomycosis is crucial, but may be hindered by the large differential diagnosis. Important diagnostic factors include a history of travel through endemic areas, ethnicity, immunologic status, involvement of multiple organ sites, and pronounced hypoxemia not accounted for by the degree of pulmonary involvement seen on chest radiograph.

Coccidioidomycosis during pregnancy. An analysis of ten cases among 47,120 pregnancies.

Previous studies have suggested that coccidioidomycosis during pregnancy is a devastating illness associated with high maternal mortality. However, this concept recently has been challenged. We examined the incidence of coccidioidomycosis during pregnancy in Tucson, Arizona, an area endemic for this infection. After reviewing the records of three separate health care facilities, we found ten cases of coccidioidomycosis among 47,120 pregnancies. Nine of the ten women had no underlying disease. Seven were diagnosed with coccidioidomycosis during either the first or second trimester. Illness resolved in all seven. Three other patients were diagnosed during the first ten days postpartum. While infection was self-limited in one woman, two others developed severe disseminated coccidioidomycosis associated with meningitis. Despite this, there were no maternal deaths. Of eight deliveries, all were uncomplicated and produced healthy infants. In summary, diagnosing coccidioidomycosis during pregnancy is rare. Although we observed no maternal death, our experience suggests that women who develop coccidioidomycosis late in pregnancy are at risk for developing severe disseminated infection.

Coccidioidomycosis--the airborne assault continues: an unusual presentation with a review of the history, epidemiology, and military relevance.

Despite remarkable advances in detection and therapy, coccidioidomycosis remains a persistent threat to military troops deployed in endemic areas. Pregnant women, immunocompromised hosts, and dark-skinned persons, particularly those of Filipino, African, Hispanic or Asian ancestry, are at greatest risk for disseminated coccidioidomycosis. The ethnically diverse military forces have susceptible active duty and reserve members stationed at or temporarily trained on bases located in endemic areas for Coccidioides immitis. Although the vast majority of infections with this organism are subclinical, unusual patterns of dissemination pose a diagnostic challenge. The military physician may be tasked with recognizing acute non-specific symptoms as well as bizarre, occult manifestations of coccidioidomycosis. We present a case of disseminated coccidioidomycosis in an active duty Caucasian male who presented with a right shoulder mass. Our patient is atypical in that he had disseminated disease although immunocompetent and Caucasian. Another unusual feature is that the mass was not preceded or accompanied by any other symptoms. We could find only two other reported cases of coccidioidomycosis presenting as a soft tissue mass, both in African-American patients. The epidemiology and history of coccidioidomycosis will be reviewed, with an emphasis on military populations. The insidious nature of coccidioidomycosis, the importance of early detection and treatment in decreasing morbidity and mortality, and the presence of large numbers of military members in the endemic areas make the lessons of this case particularly relevant for all flight surgeons.

A coccidioidomycosis outbreak following the Northridge, Calif, earthquake.

OBJECTIVE: To describe a coccidioidomycosis outbreak in Ventura County following the January 1994 earthquake, centered in Northridge, Calif, and to identify factors that increased the risk for acquiring acute coccidioidomycosis infection. DESIGN: Epidemic investigation, population-based skin test survey, and case-control study. SETTING: Ventura County, California. RESULTS: In Ventura County, between January 24 and March 15, 1994, 203 outbreak-associated coccidioidomycosis cases, including 3 fatalities, were identified (attack rate [AR], 30 cases per 100,000 population). The majority of cases (56%) and the highest AR (114 per 100,000 population) occurred in the town of Simi Valley, a community located at the base of a mountain range that experienced numerous landslides associated with the earthquake. Disease onset for cases peaked 2 weeks after the earthquake. The AR was 2.8 times greater for persons 40 years of age and older than for younger persons (relative risk, 2.8; 95% confidence interval [CI], 2.1-3.7; P<.001). Environmental data indicated that large dust clouds, generated by landslides following the earthquake and strong aftershocks in the Santa Susana Mountains north of Simi Valley, were dispersed into nearby valleys by northeast winds. Simi Valley case-control study data indicated that physically being in a dust cloud (odds ratio, 3.0; 95% CI, 1.6-5.4; P<.001) and time spent in a dust cloud (P<.001) significantly increased the risk for being diagnosed with acute coccidioidomycosis. CONCLUSIONS: Both the location and timing of cases strongly suggest that the coccidioidomycosis outbreak in Ventura County was caused when arthrospores were spread in dust clouds generated by the earthquake. This is the first report of a coccidioidomycosis outbreak following an earthquake. Public and physician awareness, especially in endemic areas following similar dust cloud-generating events, may result in prevention and early recognition of acute coccidioidomycosis.

Coccidioidomycosis in patients with hematologic malignancies.

BACKGROUND: An endemic fungal infection of the desert southwestern United States, coccidioidomycosis is generally a self-limited illness in healthy persons. Immunosuppressed persons who contract coccidioidomycosis, however, are at increased risk for disseminated infection. METHODS: We conducted a retrospective review of patients with coccidioidomycosis and hematologic malignancy or bone marrow disease. RESULTS: Fifty-five patients were identified. The most common underlying malignancies were non-Hodgkin lymphoma and chronic lymphocytic leukemia. Extrathoracic (or disseminated) infection was observed in 12 patients (22%). Fifteen patients (27%) died with active coccidioidomycosis. Treatment of the hematologic disease with corticosteroids or antineoplastic chemotherapy increased the risk of death. CONCLUSION: To date, this is the largest case series of patients with hematologic malignancy and coccidioidomycosis. In persons with hematologic malignancy, coccidioidomycosis can be a severe illness with a high risk for disseminated infection and death.

Coccidioidomycosis in pregnancy: case report and review of the literature.

BACKGROUND: Coccidioidomycosis is an uncommon fungal infection during pregnancy. We report a case and review the literature on coccidioidomycosis in pregnancy. METHODS: We searched MEDLINE (1966-2005), PubMed (1950-2005), Embase (1974-2005), the Cochrane Library, and the Index-Catalogue of the Library of the Surgeon-General's Office United States Army (1880-1961) for cases of coccidioidomycosis occurring during pregnancy. We describe a woman with disseminated coccidioidomycosis during the last trimester of pregnancy with fungemia, respiratory failure, a miliary pattern on chest radiograph, and skin and bony involvement. RESULTS: We identified 80 additional cases of coccidioidomycosis occurring with pregnancy in the literature. The mean age of patients was 26 years (range 16-38 years). Disseminated disease was strongly associated with the trimester of pregnancy; 40% of the cases diagnosed before pregnancy, 50% of the cases diagnosed in the first trimester, 62% of the cases diagnosed in the second trimester, and 96% of the cases diagnosed in the third trimester had dissemination (P<.001). In addition, African American women had a 13-fold increased risk of dissemination compared with white women (P=.007). CONCLUSIONS: Mortality rates have improved over time in association with the timely administration of antifungal therapy. Disseminated coccidioidomycosis may occur during pregnancy, especially during the third trimester. Improved maternal and fetal survival is associated with early disease recognition and administration of amphotericin B.

Coccidioidomycosis among persons with human immunodeficiency virus infection in the era of highly active antiretroviral therapy (HAART).

Coccidioidomycosis remains an important opportunistic infection among individuals infected with human immunodeficiency virus (HIV) who live in the coccidioidal endemic area. There are several manifestations of coccidioidomycosis during HIV infection, but pulmonary disease, either diffuse or focal, is the most common. The most important factor associated with the risk for developing clinically active coccidioidomycosis is a CD4 peripheral blood lymphocyte count of less than 250/microL. The advent of highly active antiretroviral therapy (HAART) for the treatment of HIV infection has changed our approach to the management of opportunistic infections, including coccidioidomycosis. Few data are available regarding the incidence of coccidioidomycosis since the initiation of HAART, but these suggest a decline. It is currently recommended that antifungal therapy for coccidioidomycosis during HIV infection be continued indefinitely, even among those with asymptomatic disease. Future studies should indicate whether this is necessary if immune function has been reconstituted through appropriate therapy for the HIV infection.
