coccidioidomycosis AND complement

Scott A Weisenberg
A 78-year-old man developed right knee pain and swelling without other systemic symptoms. He had travelled frequently to the Central Valley of California. He was diagnosed with coccidioidomycosis based on joint fluid culture. Coccidioidal complement fixation antibody titres were extremely elevated. Arthroscopic debridement and fluconazole therapy did not lead to satisfactory improvement. Subsequent open debridement and change to itraconazole was followed by resolution of clinical signs of infection.

OBJECTIVE: Coccidioidomycosis is an invasive fungal disease that may present with extrathoracic dissemination. Patients with spinal coccidioidomycosis require unique medical and surgical management. We review the risk factors and clinical presentations, discuss the indications for surgical intervention, and evaluate outcomes and complications after medical and surgical management. METHODS: A review of the English-language literature was performed. Eighteen articles included the management of 140 patients with spinal coccidioidomycosis...

Coccidioidomycosis is a common cause of community-acquired pneumonia in areas of the southwestern United States in which the disease is endemic. Clinical presentations range from self-limited disease to severe disseminated disease. Therefore, early and accurate diagnosis is essential to ensure appropriate treatment and monitoring. Currently available diagnostic tests have variable accuracy, particularly in certain patient populations, and new tests may offer improved accuracy for the diagnosis of coccidioidomycosis...

Coccidioidomycosis is an insidious infection caused by Coccidioides spp (C. immitis and C. posadasii). Disseminated disease occasionally involves tendon sheaths and synovium of the joints leading to tenosynovitis. Here, we describe the case of a 72-year-old woman from southern Arizona, who presented with right ankle pain, redness and swelling for 2 months. Her serum IgG was positive for C. immitis on complement fixation, and her MRI of the right ankle joint showed extensive tenosynovitis of the right peroneal tendons, and subtalar joint effusions with associated synovitis...

A 31-year-old Filipino active duty marine presented with a 2-year history of a waxing and waning nodule on his left cheek that had been incised and drained on multiple occasions. The patient had no significant medical history other than a positive purified protein derivative test with negative chest x-ray finding treated with a 9-month course of isoniazid in 2010. He denied cough, fever, chills, night sweats, weight loss, joint/bone pain, or prior trauma to the area. On initial examination, there was a 1×1-cm erythematous indurated nodule associated with an overlying violaceous scar on his left preauricular cheek...

BACKGROUND: Coccidioidal meningitis (CM), a common cause of chronic meningitis in endemic area, is usually diagnosed by detection of anti-Coccidioides antibodies in cerebrospinal fluid (CSF), and findings may be negative in up to one-third of cases. CSF cultures and cytology are infrequently positive. Antigen detection has been used for the diagnosis of other forms of coccidioidomycosis and meningitis caused by other mycoses. The purpose of this study was to assess the diagnostic utility of CSF Coccidioides antigen (CAg) detection for the diagnosis of CM...

Coccidioides spp. are dimorphic pathogenic fungi whose parasitic forms cause coccidioidomycosis (Valley fever) in mammalian hosts. We use an innovative interdisciplinary approach to analyze one-on-one encounters between human neutrophils and two forms of Coccidioides posadasii. To examine the mechanisms by which the innate immune system coordinates different stages of the host response to fungal pathogens, we dissect the immune-cell response into chemotaxis, adhesion, and phagocytosis. Our single-cell technique reveals a surprisingly strong response by initially quiescent neutrophils to close encounters with C...

Gastrointestinal coccidioidomycosis is extremely rare, with less than 10 cases reported in the literature. We report a case of small bowel dissemination of coccidioidomycosis in a 21-year-old African American male with a history of living in San Joaquin Valley. The patient presented with one week of abdominal pain, nausea, shortness of breath, intermittent fever, and sweat, and one month of abdominal distention. A chest radiograph revealed complete effusion of left lung. A computed tomography scan of the abdomen showed diffuse small bowel thickening and enhancement, as well as omental and peritoneal nodules, and ascites...

Coccidioides immitis and Coccidioides posadasii, the two recognized causes of coccidioidomicosis, may be diagnosed by direct microscopy, culture, serologic and the skin-test with mycelial coccidioidin. Identification of spherules by direct examination of secretions after addition of KOH, is more rapid and may speed diagnosis. Histopathology of infected tissue demonstrates acute and chronic granulomatous inflammation and in the section strained with hematoxylin-eosine (HE) or Grocott metamine-silver (GMS). Isolation of Coccidioides spp...

An 11 yr-old female Pacific walrus (Odobenus rosmarus divergens) demonstrated decreased appetite and weight loss approximately 4 wk after truck transport from a northern California facility to a southern California facility. An initial blood analysis revealed a leukocytosis of 22,800 white blood cells (WBC)/microl, with a left shift, low iron (58 microg/dl), and mild hyperglobulinemia (4.3 g/dl). Empiric antibiotic therapy was started with amoxicillin and clavulanic acid (14 mg/kg p.o. b.i.d.). Clinical improvement was observed initially; however, follow-up blood analysis demonstrated a persistent leukocytosis (24,000 WBC/microl), with left shift and progressive hyperglobulinemia (6...

Although routinely done, there has been no evaluation of the utility of performing routine cerebrospinal fluid (CSF) examination in patients with active coccidioidomycosis and high complement fixation (IgG) antibody titers or other risk factors for disseminated infection. In our review 100% of patients diagnosed with coccidioidal meningitis had at least one sign or symptom consistent with infection of the central nervous system, headache was present in 100% of those with meningitis, while no patients without signs/symptoms of CNS infection were found to have coccidioidal meningitis, irrespective of antibody titers or other risk factors...

SESSION TYPE: Infectious Disease Cases IIIPRESENTED ON: Wednesday, October 24, 2012 at 11:15 AM - 12:30 PMINTRODUCTION: Coccidioidomycosis is caused by the soil-dwelling dimorphic fungi Coccidioides immitis and Coccidioides posadasii, which are endemic in southwestern United States, as well as northwestern Mexico. The most typical clinical manifestation is asymptomatic pulmonary disease. However, a subset may develop complications, such as cavitary disease.CASE PRESENTATION: A 53-year-old Mexican man with a history of diabetes mellitus and tobacco use presented with three months of hemoptysis (one teaspoon daily), unintentional weight loss and fatigue...

BACKGROUND: Coccidioidomycosis, an endemic fungal infection seen throughout the southwestern United States, is not well described in children. METHODS: We performed a retrospective observational study of all children admitted to Children's Hospital Central California with coccidioidomycosis from 1 January 2010 to 1 September 2011. RESULTS: Thirty-three children, aged 6 months to 17 years, were hospitalized during the study period. These included patients with pneumonia (n = 28), pleural effusion (n = 13), pleural empyema (n = 4), lung abscess (n = 7), pericarditis (n = 2), osteomyelitis (n = 5), meningitis/cerebritis (n = 2), and vocal cord infection (n = 1)...

Solid organ transplant recipients who acquire coccidioidomycosis have high rates of disseminated infection and mortality, and diagnosis of infection in these immunosuppressed patients is challenging because of suboptimal sensitivity of diagnostic tests. To characterize the utility of diagnostic tests for coccidioidomycosis in this population, we conducted a retrospective chart review of all solid organ transplant recipients with newly acquired coccidioidomycosis who were seen at our institution from 1999 to 2011...

BACKGROUND: In a patient with positive serum serology for coccidioidomycosis, the differential diagnosis of concurrent pleural effusions can be challenging. We, therefore, sought to clarify the performance characteristics of biochemical, serologic, and nucleic-acid-based testing in an attempt to avoid invasive procedures. The utility of adenosine deaminase (ADA), coccidioidal serology, and polymerase chain reaction (PCR) in the evaluation of pleuropulmonary coccidioidomycosis has not been previously reported...

The diagnosis of coccidioidomycosis relies heavily on serologic test results in addition to clinical history, physical examination, and radiographic findings. Use of the enzyme immunoassay (EIA) has increased because it is rapidly performed and does not require referral to a reference laboratory, as do complement fixation and immunodiffusion tests. However, interpretation of immunoglobulin M (IgM) reactivity by EIA in the absence of immunoglobulin G (IgG) reactivity has been problematic. We conducted a retrospective medical record review of all patients with such IgM reactivity at our institution to identify situations where the finding was more likely to be clinically specific for coccidioidal infection...

Coccidioides is a fungal pathogen and causative agent of a human respiratory disease against which no clinical vaccine exists. In this study we evaluated a novel vaccine adjuvant referred to as EP67, which is a peptide agonist of the biologically active C-terminal region of human complement component C5a. The EP67 peptide was conjugated to live spores of an attenuated vaccine strain (ΔT) of Coccidioides posadasii. The non-conjugated ΔT vaccine provided partial protection to BALB/c mice against coccidioidomycosis...

BACKGROUND: We have observed a number of patients who fail to develop coccidioidal complement fixing (CF) antibody (immunoglobulin [IgG]) after the initiation of early antifungal therapy. Although this is the first description of this phenomenon in mycology, a precedent for the abrogation of the immune response has been observed in other conditions, including primary syphilis and primary Lyme disease. METHODS: We conducted a retrospective case-control study to determine any patient-specific risk factors associated with this observation...
