Abstract
The incidence and distribution of coccidioidomycosis are increasing. Information scarcity is evident in Mexico, particularly in non-endemic zones and specific populations. We compared the treatment and outcomes for patients with isolated pulmonary infections and those with disseminated coccidioidomycosis, including mortality rates within six weeks of diagnosis. Of 31 CM cases, 71% were male and 55% were disseminated. For 42% of patients, there was no evidence of having lived in or visited an endemic region. All patients had at least one comorbidity, and 58% had pharmacologic immunosuppressants. The general mortality rate was 30%; without differences between disseminated and localized disease. In our research, we describe a CM with a high frequency of disseminated disease without specific risk factors and non-significant mortality. Exposure to endemic regions was not found in a considerable number of subjects. We consider diverse reasons for why this may be, such as climate change or migration.

Abstract
Granulomas are frequently encountered by pathologists in all types of lung specimens and arise from diverse etiologies. They should always be reported as necrotizing or non-necrotizing, with microorganism stains performed to evaluate for infection. With attention to distribution, quality (poorly vs well-formed), associated features, and correlation with clinical, radiologic, and laboratory data, the differential diagnosis for granulomatous lung disease can usually be narrowed to a clinically helpful "short list." This review describes a practical approach to pulmonary granulomas and reviews the clinicopathological aspects of common entities, including infectious (mycobacteria, fungi) and noninfectious (hypersensitivity pneumonitis, sarcoid, and vasculitis) causes.

Coccidioides Serologic Screening Practices in Individuals With Rheumatic and Autoimmune Diseases. ACR Open Rheumatol 2024; 6:380-387. [PMID: 38477182 PMCID: PMC11168914 DOI: 10.1002/acr2.11663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 01/25/2024] [Accepted: 02/09/2024] [Indexed: 03/14/2024] Open
Abstract
OBJECTIVE We aimed to estimate Coccidioides serologic screening rates before initiation of biologic disease-modifying antirheumatic drugs including tofacitinib (b/tsDMARDs), conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and/or noninhaled corticosteroids. METHODS This retrospective cohort study used 2011 to 2016 US Medicare claims data and included beneficiaries with rheumatic or autoimmune disease residing in regions within Arizona, California, and Texas endemic for Coccidioides spp. with ≥1 prescription for a b/tsDMARD, csDMARD, and/or noninhaled corticosteroid. We estimated prior-year serologic screening incidence before initiating b/tsDMARDs, csDMARD, and/or noninhaled corticosteroid. RESULTS During 2012 to 2016, 4,331 beneficiaries filled 64,049 prescriptions for b/tsDMARDs, csDMARDs, and noninhaled corticosteroids. Arizona's estimated screening rate was 20.1% (95% confidence interval [95% CI] 14.5-25.7) in the year before prescription initiation for b/tsDMARDs, 8.1% (95% CI 6.5-9.7) before csDMARDs, and 6.9% (95% CI: 5.6-8.2) before corticosteroids. Screening rates for b/tsDMARDs (2.8%, 95% CI 0.0-6.7), csDMARDs (1.0%, 95% CI 0.0-2.0), and corticosteroids (0.8%, 95% CI: 0.4-1.1) were negligible in California and undetected in Texas. Adjusted screening rate before prescription for b/tsDMARDs in Arizona increased from 14.5% (95% CI 7.5-21.5) in 2012 to 26.7% (95% CI 17.6-35.8) in 2016. Rheumatologists prescribing b/tsDMARDs in Arizona screened more than other providers (20.9% [95% CI 13.9-27.9] vs 12.9% [95% CI 5.9-20.0]). CONCLUSION Coccidioides serologic screening rates among Medicare beneficiaries with rheumatic/autoimmune diseases on b/tsDMARDs, csDMARDs, and noninhaled corticosteroids was low in Coccidioides spp.-US endemic regions between 2012 and 2016. Alignment of screening recommendations and clinical practice is needed.

Abstract
The National Reference Laboratory in Clinical Mycology of Argentina conducted a retrospective review of human coccidioidomycosis cases diagnosed by the National Mycology Laboratory Network of Argentina between 2010 and 2022 to determine the burden of the disease in the country. A total of 100 human coccidioidomycosis cases were documented, with a higher prevalence in male patients (male-to-female ratio of 1.9:1), with a median age of 41 years. Comparing the number of cases between two 10-year periods (2000-2009 and 2010-2019), the increase was 36.51% (from 63 to 86 cases). Among the 100 recorded cases, 79 tested positive using the double immunodiffusion test. Spherules were observed in 19 cases through histopathology or direct microscopic examination and the fungus was isolated in 39 cases. Thirty-six isolates were identified as Coccidioides posadasii through partial sequencing of the Ag2/PRA gene. Catamarca province had the highest number of cases, comprising 64% of the total, with an incidence rate above 1.0-2.5/100,000 inhabitants until 2018. However, there has been a recent downward trend in the region from 2018 to 2022. It is concerning that more than half of diagnosed cases were chronic pulmonary or disseminated forms, indicating a lack of early disease detection. To rectify this issue, it is imperative to conduct targeted training programs for healthcare personnel and enhance public awareness within the endemic area. This will contribute to a better understanding of the true burden of coccidioidomycosis and enable the implementation of appropriate sanitary control measures.

Abstract
PURPOSE OF REVIEW The recent COVID-19 pandemic has shaped the epidemiology of other infectious diseases globally. International tourist arrivals are increasing and recovering to prepandemic levels. This review focuses on respiratory infections in travelers, highlighting the characteristics of the main imported viral, bacterial, fungal, and parasitic infections with pulmonary involvement. RECENT FINDINGS A recent systematic review estimated a prevalence of respiratory symptoms in travelers of around 35%, increasing to nearly 65% in the context of mass gatherings. Common viral and bacterial pathogens account for the majority of respiratory infections with an identified cause; however, recent data focus on the need for surveillance of emerging infections such as MERS-CoV, henipaviruses and multidrug resistant bacteria, which may be spread through travel. Fungal and parasitic respiratory infections are less common, and acquisition is usually associated with specific risk factors or exposure in endemic areas. Special risk groups, such as immunocompromised travelers, may be particularly vulnerable, presenting with severe disease or reactivation of latent infections. SUMMARY The next significant international epidemic could involve another new infectious agent causing respiratory disease and spreading via mobile populations. Official protocols should be adhered to, and public health interventions implemented for effective control. Continued and globally coordinated investments in research for new vaccines, therapeutic agents, disease modeling, and digital tracking strategies are essential.

Abstract
PURPOSE Coccidioidomycosis, caused by the Coccidioides species, is a well-known disease in the Southwestern United States and North Mexico, with scattered reports in Latin America countries. While this disease is still rare in Japan and other Asian countries, its incidence has been increasing over the last two decades. Coccidioides species are highly infectious and require caution when encountered. This study presents a case series of chronic pulmonary coccidioidomycosis surgically treated at a single institution. METHODS We conducted a retrospective chart review of six patients who underwent lung resection for pulmonary coccidioidomycosis at Chiba University Hospital between January 2007 and December 2021. RESULTS All six patients had travelled to the Southwestern United States. Preoperative serology was negative for the anti-Coccidioides antibody in four patients and positive in two. Chest computed tomography revealed a single, well-defined round nodule in all patients. Preoperative biopsy taken from three patients failed to obtain a definitive diagnosis. Histopathological examination of the resected pulmonary nodules revealed granulomas that contained numerous spherules with many endospores, thereby confirming the diagnosis of pulmonary coccidioidomycosis. CONCLUSIONS Pulmonary coccidioidomycosis should be suspected based on travel history and radiological findings. Meticulous care should be taken during specimen processing to prevent cross infection.

Abstract
Valley Fever is a respiratory disease caused by inhalation of arthroconidia, a type of spore produced by fungi within the genus Coccidioides spp. which are found in dry, hot ecosystems of the Western Hemisphere. A quantitative microbial risk assessment (QMRA) for the disease has not yet been performed due to a lack of dose-response models and a scarcity of quantitative occurrence data from environmental samples. A literature review was performed to gather data on experimental animal dosing studies, environmental occurrence, human disease outbreaks, and meteorological associations. As a result, a risk framework is presented with information for parameterizing QMRA models for Coccidioides spp., with eight new dose-response models proposed. A probabilistic QMRA was conducted for a Southwestern US agricultural case study, evaluating eight scenarios related to farming occupational exposures. Median daily workday risks for developing severe Valley Fever ranged from 2.53 × 10-7 (planting by hand while wearing an N95 facemask) to 1.33 × 10-3 (machine harvesting while not wearing a facemask). The literature review and QMRA synthesis confirmed that exposure to aerosolized arthroconidia has the potential to result in high attack rates but highlighted that the mechanistic relationships between environmental conditions and disease remain poorly understood. Recommendations for Valley Fever risk assessment research needs in order to reduce disease risks are discussed, including interventions for farmers.

Abstract
Coccidioidomycosis is a fungal infection primarily Endemic in the Southwest United States. Disseminated Coccidioidomycosis is a life-threatening variant that mainly occurs in an immunocompromised host. This report describes an unusual presentation of disseminated Coccidioidomycosis in an immunocompetent individual. The patient was admitted with a subacute cough, progressively worsening shortness of breath, significant weight loss, nodular skin lesions in upper extremities, and acute hypoxemic respiratory failure. Chest imaging revealed extensive nodularity and mass-like lesions. What sets this case apart is the significant endotracheal and endobronchial involvement, which mimicked metastatic lung cancer. The diagnosis was confirmed through serology and bronchoscopy biopsy. This case underscores the critical importance of considering detailed travel history and maintaining a high index of suspicion for fungal infections in patients with endobronchial lesions, particularly in regions where Coccidioidomycosis is endemic.

Abstract
Coccidioides is an endemic fungus that causes infections ranging from mild respiratory illness to life-threatening disease, and immunocompromised hosts such as solid organ transplant recipients are at higher risk for disseminated infection and mortality. Our center administers fluconazole prophylaxis to kidney transplant recipients residing in geographic areas with higher incidences of coccidioidomycosis. However, because drug-drug interactions occur between triazoles and immunosuppressants used in transplant medicine, we undertook a study to ascertain whether fluconazole prophylaxis was associated with any important safety outcomes in kidney transplant recipients. This retrospective study evaluated patients who had undergone kidney transplantation between 2016 and 2019. Data on patient demographics, transplant-related clinical information, use of fluconazole prophylaxis (200 mg daily for 6-12 months post-transplant), and patient outcomes were obtained. The primary outcome was mean estimated glomerular filtration rate (eGFR) at 12 months, comparing those who received fluconazole prophylaxis to those who did not. Secondary outcomes included mean eGFR at 3 months, 6 months, and 9 months post-transplant, patient survival, biopsy-proven graft rejection, graft loss, or a new requirement for post-transplant dialysis, all within 12 months post-transplant. The mean eGFR at 12 months was similar between both groups, with 66.4 ml/min/1.73 m² in the fluconazole prophylaxis group vs. 64.3 ml/min/1.73 m² in the non-fluconazole prophylaxis group (P = 0.55). Secondary outcomes were similar across both groups. Multivariable linear regression found no significant association between fluconazole use and graft function. Fluconazole prophylaxis for prevention of coccidioidomycosis was not associated with adverse graft outcomes in kidney transplant recipients.

The Ecology of Non- Candida Yeasts and Dimorphic Fungi in Cetaceans: From Pathogenicity to Environmental and Global Health Implications. J Fungi (Basel) 2024; 10:111. [PMID: 38392783 PMCID: PMC10889755 DOI: 10.3390/jof10020111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/20/2024] [Accepted: 01/24/2024] [Indexed: 02/24/2024] Open
Abstract
Cetaceans, which are integral to marine ecosystems, face escalating anthropogenic threats, including climate change and pollution, positioning them as critical sentinel species for ocean and human health. This review explores the neglected realm of non-Candida yeasts in cetaceans, addressing the gaps in the understanding of their prevalence, pathogenicity, and environmental impacts. By examining identified species such as Cryptococcus spp., Paracoccidioides spp., and several dimorphic fungi, this review emphasizes global prevalence, epidemiology and ecology, pathogenicity, and potential zoonotic implications. It also discusses the fine line between yeast commensalism and pathogenicity by considering environmental influences such as pollution, climate shifts, and immune suppression. Environmental impact discussions delve into how rising ocean temperatures and pollution can modify yeast mycobiota, potentially affecting marine host health and broader ecosystem dynamics. The cetacean's unique physiology and ecological niches are considered, highlighting potential impacts on behaviors, reproductive success, and survival rates. Identifying crucial knowledge gaps, the review calls for intensified research efforts, employing advanced molecular techniques to unravel the cetacean mycobiome. Systematic studies on yeast diversity, antifungal susceptibility, and their influence on environmental and ecosystem health are proposed, and the balance between commensal and pathogenic species emphasizes the significance of the One Health approach. In conclusion, as marine mammals face unprecedented challenges, unveiling non-Candida yeasts in cetaceans emerges as a critical endeavor with far-reaching implications for the conservation of marine ecosystems and for both animal and human public health.

Abstract
Voriconazole-induced periostitis is a rare adverse effect in patients on long-term therapy, characterised by periosteal inflammation and associated bony pain. The accompanying lab abnormalities (elevated serum alkaline phosphatase and fluoride) and characteristic imaging findings (uptake of radionuclide tracer on nuclear bone scan) are critical for diagnosis. The disease process is thought to be secondary to excess fluoride from voriconazole which stimulates bone formation and decreases osteoclast bone resorption. Management includes stopping voriconazole and switching to another agent.

Abstract
Coccidioides is the fungal causative agent of Valley fever, a primarily pulmonary disease caused by inhalation of fungal arthroconidia, or spores. Although Coccidioides has been an established pathogen for 120 years and is responsible for hundreds of thousands of infections per year, little is known about when and where infectious Coccidioides arthroconidia are present within the ambient air in endemic regions. Long-term air sampling programs provide a means to investigate these characteristics across space and time. Here we present data from > 18 months of collections from 11 air sampling sites across the Phoenix, Arizona, metropolitan area. Overall, prevalence was highly variable across space and time with no obvious spatial or temporal correlations. Several high prevalence periods were identified at select sites, with no obvious spatial or temporal associations. Comparing these data with weather and environmental factor data, wind gusts and temperature were positively associated with Coccidioides detection, while soil moisture was negatively associated with Coccidioides detection. These results provide critical insights into the frequency and distribution of airborne arthroconidia and the associated risk of inhalation and potential disease that is present across space and time in a highly endemic locale.

Abstract
Although Valley fever represents a growing public health challenge for Central and Southern Californian residents, awareness remains severely limited. The California Department of Public Health (CDPH) ran a cross-platform campaign to mitigate this awareness gap and impact prevention behavior. This study evaluates exposure to the CDPH campaign, followed by an examination of the information consumption patterns associated with key health outcomes. Results suggest that the CDPH campaign successfully improved knowledge accuracy, reduced misperceptions, and increased the likelihood of prevention behavior. Using an information repertoire lens revealed a more nuanced account. Most information repertoires positively influenced accurate knowledge retention and prevention behavior compared to those who were not exposed. The most diverse information repertoire, including interpersonal and media channels, was associated with increased knowledge accuracy, affective risk concerns, personal susceptibility, and prevention behavior. However, exposure to this repertoire was also associated with greater misperceptions. In addition, medical professional and radio-based repertoires positively influenced personal susceptibility perceptions. Overall, this research illustrates the importance of examining not only the general outcomes of health campaigns but also the patterns of information acquisition - particularly when working with underserved communities whose health information consumption preferences may not be comprehensively reflected in the literature.

Abstract
While rare, the likelihood of encountering a case of a pulmonary endemic mycosis (PEM) in the UK is increasing. Diagnosis may be challenging, often leading to considerable delay to appropriate treatment. Clinical suspicion must be present for respiratory disease, particularly in the immunocompromised or in those not responding to empiric treatment approaches, and an extended travel history should be obtained. This article summarises the epidemiology of PEM, key clinical features, diagnostic strategies and management.

Abstract
Coccidioidomycosis, also termed Valley fever, is a fungal infection caused by the inhalation of Coccidioides endospores. Once inhaled by a human host, the arthroconidia endospores travel to the lungs' alveoli to transform into spherules that grow and rupture to release more endospores. In the host immune response, macrophages, neutrophils, and dendritic cells will recognize the fungal antigen, producing pro-inflammatory cytokine. Th2 lymphocytes (type 2 helper T cells) are theorized to be the main human defense against Coccidioides given that Th2 deficiency is seen in patients with disseminated forms of the disease. A common triad of symptoms of coccidioidomycosis, also called "desert rheumatism," include fever, erythema nodosum, and arthralgia, often accompanied by a respiratory problem. In a clinical setting, along with the evaluation of symptoms, a medical provider may also test the patient's blood using antibody tests or perform microscopy to directly detect the presence of Coccidioides in a patient tissue sample for confirmation of a diagnosis. Imaging modalities may also be used to determine lung involvement and assess disease progression. A majority of coccidioidomycosis cases do not require specific treatment and will resolve on their own, so an approach with symptomatic treatment in mind is appropriate. If symptoms do not resolve, azoles or amphotericin B may be used, with the standard drug of choice being fluconazole (Diflucan, Pfizer, New York, New York, United States). Treatment varies depending on the immunocompetency of the patient. To name a few, pregnant patients and those with history of human immunodeficiency virus (HIV) or transplantation require special considerations.

Abstract
Cutaneous Coccidioidomycosis (CC) infection can present with a wide variety of clinical presentations and is well known as a 'great imitator'. We performed a retrospective analysis of patients with CC in a large referral center in Central Valley, California, from 2010 to 2022 using the ICD9 and ICD10 codes for coccidioidomycosis and CC. We identified 40 patients with CC during the study period. The mean age of the study population was 43 years (with standard deviation of 14.08). Among these, 60% were men and 40% women. The appearance of the lesions varied from ulcers, plaques, nodules, blisters, cellulitis, and abscesses. The most common site of CC lesions was in the lower extremities (42.5%), followed by upper extremities (30%), chest and abdomen, head and neck (25% each). Only 22.5% of the 40 cases were diagnosed as CC and 15% were diagnosed as erythema nodosum. Rest were diagnosed initially as bacterial cellulitis in 37.5%, tinea in 7.5%, and others in 12.5%. There was resolution of the cutaneous lesions in all patients with antifungal treatment. The mean time of diagnosis from onset of symptoms on an average was 12 weeks (8-16 weeks) in our study with 75% cases initially misdiagnosed. Comprehensive knowledge about the manifestations and evaluation of CC among primary care providers and emergency room physicians is essential to prevent delays in diagnosis and treatment.

Abstract
Coccidioidomycosis, caused by Coccidioides immitis and C. posadasii, causes significant morbidity and mortality, both in immunocompetent and immunocompromised people, mainly in endemic areas. The present work analyzed its epidemiology, diagnostic methods, and treatment by reviewing clinical cases published from 1950 to 2021. Fifty-nine articles were included, corresponding to 275 clinical cases. The results showed a higher incidence of coccidioidomycosis in the male gender than the female gender. The most affected age group was 31-40 years, and the most reported clinical presentation was disseminated with greater involvement in cutaneous and subcutaneous tissue, followed by the CNS, bone system, and peritoneum. The species most frequently reported was C. immitis. The most used treatment was azoles, followed by their combination with amphotericin B, monotherapy with amphotericin B, and alternative medicine. This work shows that epidemiological data outside the USA are still scarce. Serological tests are the preferred diagnostic method in daily medical practice, and cultures remain the gold standard. The treatment for coccidioidomycosis is ketoconazole and amphotericin B, individually or in combination.

Abstract
Valley fever or coccidioidomycosis is a pulmonary infection caused by species of Coccidioides fungi that are endemic to California and Arizona. Skeletal coccidioidomycosis accounts for about half of disseminated infections, with the vertebral spine being the preferred site of dissemination. Most cases of skeletal coccidioidomycosis progress to bone destruction or spread to adjacent structures such as joints, tendons, and other soft tissues, causing significant pain and restricting mobility. Manifestations of such cases are usually nonspecific, making diagnosis very challenging, especially in non-endemic areas. The lack of basic knowledge and research data on the mechanisms defining susceptibility to extrapulmonary infection, especially when it involves bones and joints, prompted us to survey available clinical and animal data to establish specific research questions that remain to be investigated. In this review, we explore published literature reviews, case reports, and case series on the dissemination of coccidioidomycosis to bones and/or joints. We highlight key differential features with other conditions and opportunities for mechanistic and basic research studies that can help develop novel diagnostic, prognostic, and treatment strategies.

Abstract
Background Pneumonia is the leading infectious cause of death among children under five globally. Objective The study aims to determine socio-demographic factors associated with the severity of pneumonia among children under five in Wasit Governorate. Methods A cross-sectional study and convenience sampling (non-probability) were conducted among 477 children admitted to Wasit governorate hospitals. This sample was distributed throughout five hospitals selected using convenience sampling techniques, including AL-Zahra Hospital, AL-Numaniyah General Hospital, AL-Karama Teaching Hospital, Martyr Fairouz General Hospital, and AL-Kut Gynecology Hospital. It was conducted from October 1st, 2022, to May 1st, 2023. Through questionnaires, data were collected and analyzed through descriptive and inferential statistics. Results The results showed that the participants' distribution according to pneumonia severity was such that the majority of children (81%) included in the study suffered from pneumonia. 14% of children suffered from very severe pneumonia, and 5% suffered from severe pneumonia. The children at risk of developing pneumonia were within the age group of 1-11 months (55.6%), were male (60.6%), and resided in urban areas (63.7%). Both the mother and the father had completed their primary education (50.9% and 47.4%, respectively), and 99.4% and 97.5% of the mothers were married and housewives. More than half of the fathers, 59.5%, were self-employed, and 25.6% suffered from house overcrowding. In addition, 65% had low socioeconomic status. There was a significant relationship between pneumonia severity and the father's occupation and socioeconomic status. Conclusions This study concludes that pneumonia was the most common diagnosis at admission. Among the risk factors studied, low socioeconomic status and the father's occupation were significant risk factors for pneumonia in children.

[PMID: 37504720 PMCID: PMC10381299 DOI: 10.3390/jof9070731] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/29/2023] [Accepted: 07/05/2023] [Indexed: 07/29/2023] Open
Abstract
We describe the epidemiology of coccidioidomycosis among a national cohort of Veterans. Using electronic health record data from adults tested for coccidioidomycosis between 1 January 2013 and 31 December 2022, we analyzed differences in baseline demographics (age, sex, race/ethnicity, birth country, comorbidities, residence, and Charlson Comorbidity Index score) between 4204 coccidioidomycosis-test-positive and 63,322 test-negative Veterans. Log-binomial regression models with adjusted risk ratios (aRRs) were used to evaluate risk factors associated with coccidioidomycosis including dissemination, hospitalization, and mortality. Case counts and incidence rates were highest in select counties in Arizona and California where Coccidioides is endemic. Coccidioidomycosis-positive Veterans were younger, more likely to be male, and Philippine-born. The risk factors most highly associated with being coccidioidomycosis-positive included Native Hawaiian/Pacific Islander (aRR 1.068 [95%CI: 1.039-1.098]), Asian (aRR 1.060 [95%CI: 1.037-1.083]), Black (aRR 1.029 [95%CI: 1.022-1.036]), American Indian/Alaska Native (aRR 1.026 [95%CI: 1.004-1.048]) race, and Hispanic/Latino ethnicity (aRR 1.021 [95%CI: 1.013-1.028]). Black race (aRR: 1.058 [95%CI: 1.037-1.081]) and Hispanic/Latino ethnicity (aRR 1.018 [95%CI: 1.0003-1.036]) were also associated with disseminated coccidioidomycosis, strengthening the evidence for the association of coccidioidomycosis, including severe infections, with specific racial and ethnic groups. There were no statistically significant differences in hospitalization within 45 days of testing or 30-day all-cause mortality. Improving our understanding of coccidioidomycosis risk factors is important for targeted prevention strategies and to reduce delays in diagnosis and ineffective treatment.

Abstract
Introduction: Spinal Coccidioidomycosis, although rare, represents the most frequent osseous presentation of Coccidioides spp infection. The present review aims to describe the anatomical distribution, the epidemiological characteristics, and the diagnostic and therapeutic approach of this severe infection. Methods:A meticulous review of all published spinal Coccidioidomycosis cases was carried out. The studied population's demographics and the anatomical distribution of the infection were recorded. Furthermore, the medical and operative management as well as the disease outcome were studied. Results:Seventy-six cases (of which 78.9% males) with a mean age of 35.5 years were located. Regarding the anatomical distribution of the infection, the thoracic area was the most commonly affected spine region (26.3%). Among the studied patients, 14 (18.4%) were immunocompromised. Pain was the most commonly reported symptom (21.1%). Regarding the diagnostic approach of this infection, plain x-ray or CT scan indicated the disease in the majority of cases (44.7%). Pathology (48.7%), serology (42.1%) and microbiological examinations (35.5%) further established the firm diagnosis, with Coccidioides immitis being the most frequently isolated fungus. Medical management included mainly amphotericin B (in 57.9% of cases), followed by fluconazole (in 38.2% of cases). The disease required surgical intervention in the majority of cases (76.3%), while the infection had a successful outcome in 80.3% of cases. Conclusion:Spinal Coccidioidomycosis seems to require prolonged medical treatment, including proper antifungal therapy and, in most cases, operative management. Multidisciplinary approach, including infectious disease specialists, orthopaedic and/or spine surgeons, microbiologists and radiologists seems to be of utmost important for yielding favorable outcomes.

Abstract
Fungal pathogens have become an increasingly important topic in recent decades. Yet whilst various cankers and blights have gained attention in temperate woodlands and crops, the scope for fungal pathogens of animals and their potential threat has received far less attention. With a shifting climate, the threat from fungal pathogens is predicted to increase in the future, thus understanding the spread of fungi over landscapes as well as taxa that may be at risk is of particular importance. Cave ecosystems provide potential refugia for various fungi, and roosts for bats. With their well vascularized wings and wide-ranging distributions, bats present potential fungal vectors. Furthermore, whilst bat immune systems are generally robust to bacterial and viral pathogens, they can be susceptible to fungal pathogens, particularly during periods of stress such as hibernation. Here we explore why bats are important and interesting vectors for fungi across landscapes and discuss knowledge gaps that require further research.

Abstract
Coccidioidomycosis is a fungal disease associated with soil exposure that frequently goes undiagnosed due at least in part to its nonspecific presentation and the lack of clinical suspicion by health care providers. Currently available diagnostics for coccidioidomycosis offer qualitative results that can suffer from low specificity, while semiquantitative assays are labor-intensive and complex and can require multiple days to complete. Furthermore, significant confusion exists regarding the optimal diagnostic algorithms and appropriate usage of available diagnostic tests. This review aims to inform clinical laboratorians and treating clinicians about the current diagnostic landscape, appropriate diagnostic strategies, and future diagnostic directions for coccidioidomycosis, which is expected to become more prevalent due to increased migration into areas of endemicity and climate changes.

Abstract
Coccidioides species are thermally dimorphic fungi found in geographically defined areas of the Western Hemisphere. The primary portal of entry is respiratory, with symptomatic pneumonic diseases as the most common presentation. Subsequent pulmonary complications as well as extrapulmonary metastatic infection may occur, either of which may be the presenting disease manifestation. Cavitary lung disease may be found incidentally or when investigating symptoms such as cough or hemoptysis. This study aims to explore the spectrum of coccidioidal cavities and the evaluation and management in a cohort of patients seen at Kern Medical over the last 12 years.

Abstract
Fungal infections are a significant source of morbidity in the lung transplant population via direct allograft damage and predisposing patients to the development of chronic lung allograft dysfunction. Prompt diagnosis and treatment are imperative to limit allograft damage. This review article discusses incidence, risk factors, and symptoms with a specific focus on diagnostic and treatment strategies in the lung transplant population for fungal infections caused by Aspergillus, Candida, Coccidioides, Histoplasma, Blastomyces, Scedosporium/Lomentospora, Fusarium, and Pneumocystis jirovecii. Evidence for the use of newer triazole and inhaled antifungals to treat isolated pulmonary fungal infections in lung transplant recipients is also discussed.

Abstract
Coccidioidomycosis is a rare infection caused by the dimorphic fungi Coccidiodes immitus or Coccidioides posadasii. This fungal infection is very common in the American Southwest as well as northern Mexico. Though the fungus is ubiquitous, symptomatic coccidioidomycosis usually occurs in the elderly or immunocompromised. This case report discusses a unique instance of an immunocompetent 29-year-old male without any notable past medical history who was found to have a coccidioidal cavitary lung lesion with concomitant pyopneumothorax.

Abstract
There is a scarcity of data on endemic and regionally limited fungal and parasitic infections in recipients of haematopoietic stem-cell transplantation (HSCT) outside western Europe and North America. This Worldwide Network for Blood and Marrow Transplantation (WBMT) Review is one of two papers aiming to provide guidance to transplantation centres worldwide regarding prevention, diagnosis, and treatment based on the currently available evidence and expert opinion. These recommendations were created and reviewed by physicians with expertise in HSCT or infectious disease, representing several infectious disease and HSCT groups and societies. In this paper, we review the literature on several endemic and regionally limited parasitic and fungal infections, some of which are listed as neglected tropical diseases by WHO, including visceral leishmaniasis, Chagas disease, strongyloidiasis, malaria, schistosomiasis, histoplasmosis, blastomycosis, and coccidioidomycosis.

Abstract
Biological particles, along with inorganic gaseous and particulate pollutants, constitute an ever-present component of the atmosphere and surfaces. Among these particles are fungal species colonizing almost all ecosystems, including the human body. Although inoffensive to most people, fungi can be responsible for several health problems, such as allergic fungal diseases and fungal infections. Worldwide fungal disease incidence is increasing, with new emerging fungal diseases appearing yearly. Reasons for this increase are the expansion of life expectancy, the number of immunocompromised patients (immunosuppressive treatments for transplantation, autoimmune diseases, and immunodeficiency diseases), the number of uncontrolled underlying conditions (e.g., diabetes mellitus), and the misusage of medication (e.g., corticosteroids and broad-spectrum antibiotics). Managing fungal diseases is challenging; only four classes of antifungal drugs are available, resistance to these drugs is increasing, and no vaccines have been approved. The present work reviews the implications of fungal particles in human health from allergic diseases (i.e., allergic bronchopulmonary aspergillosis, severe asthma with fungal sensitization, thunderstorm asthma, allergic fungal rhinosinusitis, and occupational lung diseases) to infections (i.e., superficial, subcutaneous, and systemic infections). Topics such as the etiological agent, risk factors, clinical manifestations, diagnosis, and treatment will be revised to improve the knowledge of this growing health concern.

Abstract
Fungal infections are a serious global concern because of their ability to spread and colonize host tissues in immunocompromised individuals. Such infections have been frequently reported worldwide and are currently gaining clinical research relevance owing to their resistant character, representing a bottleneck in treating affected people. Resistant fungi are an emergent public health threat. The upsurge of such pathogens has led to new research toward unraveling the destructive potential evoked by these species. Some fungi-grouped into Candida, Aspergillus, and Cryptococcus-are causative agents of severe and systemic infections. They are associated with high mortality rates and have recently been described as sources of coinfection in COVID-hospitalized patients. Despite the efforts to elucidate the challenges of colonization, dissemination, and infection severity, the immunopathogenesis of fungal diseases remains a pivotal characteristic in fungal burden elimination. The struggle between the host immune system and the physiological strategies of the fungi to maintain cellular viability is complex. In this brief review, we highlight the relevance of drug resistance phenotypes in fungi of clinical significance, taking into consideration their physiopathology and how the scientific community could orchestrate their efforts to avoid fungal infection dissemination and deaths.

Abstract
Coccidioidomycosis (CM) and paracoccidioidomycosis (PCM) are systemic mycoses that are highly endemic in Latin America and have recently been included on the World Health Organization (WHO) Fungal Priority Pathogens List. Coccidioides immitis and Coccidioides posadasii are recognized as etiological agents of CM, with peculiarities in their geographic distribution. The genus Paracoccidioides now includes Paracoccidioides lutzii and the Paracoccidioides brasiliensis complex, which encompasses four phylogenetic species. In both diseases, pulmonary signs and symptoms are the main reasons for patients to seek medical assistance, and they are frequently misdiagnosed as tuberculosis. In this paper, we present a critical view of the strategies for diagnosis and clinical management of CM and PCM. Over the past few decades, there has been an increase in the number of reports of endemic fungal infections in areas previously thought to be "non-endemic" due to climate change and increased travel, among other factors. Learning to recognize their main epidemiological aspects and clinical manifestations is crucial so that clinicians can include them in the differential diagnosis of lung disease and avoid late diagnosis.

J Investig Med High Impact Case Rep 2023; 11:23247096231197863. [PMID: 37700666 PMCID: PMC10501056 DOI: 10.1177/23247096231197863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 08/07/2023] [Accepted: 08/13/2023] [Indexed: 09/14/2023] Open
Abstract
Cavitary pulmonary coccidioidomycosis is rare diagnosis with an incidence of 13% to 15% of pulmonary coccidioidomycosis cases. High clinical suspicion is necessary in the setting of geographical location endemicity. We present a 49-year-old male who has lived in the Coachella Valley of California for several years, with a medical history of uncontrolled type 2 diabetes who noted 1 week of right-sided chest pain with shortness of breath, fever, chills, night sweats, and weight loss. A chest X-ray revealed a 4- to 5-cm mass in the right lung. Initial workup revealed negative sputum cultures (aerobic/anaerobic, acid-fast bacilli). However, dedicated fungal cultures (samples from sputum, lymph nodes, lung right lower lobe bronchial swabs), bronchial washings, and surgical tissue biopsy of the right lower lobe revealed mold. The patient underwent right thoracotomy with right lower lobectomy and right mediastinal lymph node dissection for both diagnostic (lung specimen) and therapeutic (removing necrotic lung tissue, source control) purposes. Finally, serum Coccidioides antigens were positive and antibody titers were positive at 1:8; surgical biopsy of the right lower lobe grew mold that came back positive for Coccidioides posadasii. Targeted pharmacotherapy was commenced using intravenous fluconazole and then oral fluconazole for 3 months was prescribed upon discharge. The patient had gradual improvement of his shortness of breath and was instructed to follow-up at an infectious disease clinic.

Abstract
Coccidioidomycosis is an endemic disease that is particularly prevalent in the United States. However, its geographic distribution is becoming widespread. Here, we present a Japanese male who resided in the United States for 1 year, where he was diagnosed with pulmonary coccidioidomycosis that was accompanied by cavity formation. He did not tolerate antifungal therapy and consequently underwent partial resection of the upper lobe of his left lung upon his return to Japan. The patient's symptoms improved after surgery. The trend toward global networking and logistics means that a diagnosis of coccidioidomycosis should be considered in routine practice in nonendemic areas. Due to the rarity of surgical treatment for this disease, prolonged follow-up is necessary. During the last follow-up, the patient was symptom-free.

Abstract
Granulomas have been defined as inflammatory infiltrates formed by recruitment of macrophages and T cells. The three-dimensional spherical structure typically consists of a central core of tissue resident macrophages which may merge into multinucleated giant cells surrounded by T cells at the periphery. Granulomas may be triggered by infectious and non-infectious antigens. Cutaneous and visceral granulomas are common in inborn errors of immunity (IEI), particularly among patients with chronic granulomatous disease (CGD), combined immunodeficiency (CID), and common variable immunodeficiency (CVID). The estimated prevalence of granulomas in IEI ranges from 1%-4%. Infectious agents causing granulomas such Mycobacteria and Coccidioides presenting atypically may be 'sentinel' presentations for possible underlying immunodeficiency. Deep sequencing of granulomas in IEI has revealed non-classical antigens such as wild-type and RA27/3 vaccine-strain Rubella virus. Granulomas in IEI are associated with significant morbidity and mortality. The heterogeneity of granuloma presentation in IEI presents challenges for mechanistic approaches to treatment. In this review, we discuss the main infectious triggers for granulomas in IEI and the major forms of IEI presenting with 'idiopathic' non-infectious granulomas. We also discuss models to study granulomatous inflammation and the impact of deep-sequencing technology while searching for infectious triggers of granulomatous inflammation. We summarize the overarching goals of management and highlight the therapeutic options reported for specific granuloma presentations in IEI.

Abstract
The human fungal pathogen Coccidioides spp. causes valley fever, a treatment-refractory and sometimes deadly disease prevalent in arid regions of the western hemisphere. Fungal virulence in the mammalian host hinges on a switch between growth as hyphae and as large spherules containing infectious spores. How these virulence programs are encoded in the genome remains poorly understood. Drawing on Coccidioides genomic resources, we first discovered a new facet of genome organization in this system: spherule-gene islands, clusters of genes physically linked in the genome that exhibited specific mRNA induction in the spherule phase. Next, we surveyed copy-number variation genome-wide among strains of C. posadasii. Emerging from this catalog were spherule-gene islands with striking presence-absence differentiation between C. posadasii populations, a pattern expected from virulence factors subjected to different selective pressures across habitats. Finally, analyzing single-nucleotide differences across C. posadasii strains, we identified signatures of natural selection in spherule-expressed genes. Together, our data establish spherule-gene islands as candidate determinants of virulence and targets of selection in Coccidioides.

Abstract
The endemic mycoses blastomycosis, coccidioidomycosis, histoplasmosis, paracoccidioidomycosis, cryptococcosis, sporotrichosis, talaromycosis, adiaspiromycosis, and emergomycosis are mostly caused by geographically limited thermally dimorphic fungi (except for cryptococcosis), and their diagnoses can be challenging. Usual laboratory methods involved in endemic mycoses diagnosis include microscopic examination and culture of biological samples; however, serologic, histopathologic, and molecular techniques have been implemented in the last few years for the diagnosis of these mycoses since the recovery and identification of their etiologic agents is time-consuming and lacks in sensitivity. In this review, we focus on the immunologic diagnostic methods related to antibody and antigen detection since their evidence is presumptive diagnosis, and in some mycoses, such as cryptococcosis, it is definitive diagnosis.

Abstract
We discuss several issues raised by Comrie (2021, https://doi.org/10.1029/2021GH000504), which uses a crowdsourced data set to study dust storms and coccidioidomycosis (Valley fever). There is inconsistency in the term "dust storm" used by science communities. The dust data from National Oceanic and Atmospheric Administration Storm Events Database are from diverse sources, unsuitable for assessing dust-coccidioidomycosis relationships. Population exposure to dust or Coccidioides needs to consider the frequency, magnitude, and duration of dust events. Given abundant evidence that dust storms are a viable driver to transport pathogens, it is in best public interest to advocate dust storms may put people at risk for contracting Valley fever.
