Association between neuroimaging and clinical outcomes in individuals with central nervous system cryptococcosis.

BACKGROUND: The radiological manifestations of central nervous system (CNS) cryptococcosis are diverse and often subtle. There is heterogeneity on how different neuroimaging patterns impact prognosis. This study aims to assess the association between the neuroimaging and clinical outcomes of CNS cryptococcosis. METHODS: All patients with CNS cryptococcosis between July 2017 and April 2023 who underwent brain magnetic resonance imaging (MRI) were included. The primary outcome was mortality during hospitalisation. Secondary outcomes were readmission, ventricular shunting, duration of hospitalisation and time to the first negative cerebrospinal fluid culture. We compared the outcomes for each of the five main radiological findings on the brain MRI scan. RESULTS: We included 46 proven CNS cryptococcosis cases. The two main comorbidity groups were HIV infection (20, 43%) and solid organ transplantation (10, 22%), respectively. Thirty-nine patients exhibited at least one radiological abnormality (85%), with the most common being meningeal enhancement (34, 74%). The mortality rates occurred at 11% (5/46) during hospitalisation. We found no significant disparities in mortality related to distinct radiological patterns. The presence of pseudocysts was significantly associated with the need for readmission (p = .027). The ventricular shunting was significantly associated with the presence of pseudocysts (p = .005) and hydrocephalus (p = .044). CONCLUSION: In this study, there is no association between brain MRI findings and mortality. Larger studies are needed to evaluate this important issue.

Clinical and immunological features of laryngeal cryptococcosis.

The literature holds few descriptions on immune response findings for laryngeal cryptococcosis. Immunology has been more extensively described in cases involving the central nervous system and the lungs, although many of these studies were conducted in animal models. We aimed to analyze the clinical and immunological characteristics of three patients with laryngeal cryptococcosis. We observed a weak participation of the innate immune response, whereas adaptive immunity showed the predominance of a Th2-type response over a Th1-type response. Most cases occur in male older adults with immunosuppressive conditions, of which HIV infection was absent. Hoarseness configured the main symptom. We found a disease that was restricted to the larynx and possibly the lungs by contiguity. Patients with hoarseness and lesions in nasal endoscopy should be investigated for cryptococcosis by a biopsy of the larynx, including with negative serum cryptococcal antigen. The immunological aspects of our findings of laryngeal involvement resembled those in the most commonly affected systems.

Histoplasmosis in a fingolimod-treated patient: case report and scoping review.

Fingolimod is a sphingosine-1-phosphate receptor modulator used to treat multiple sclerosis. While fingolimod has been associated with an increased risk of cryptococcal meningitis, its correlation with other deep mycoses remains unclear. In this study, we conducted a scoping review of fingolimod associated with histoplasmosis, based on a case report, a literature review, and data from the FDA Adverse Events Reporting System (FAERS) as of January 24th, 2023. A 30-year-old Brazilian woman diagnosed with relapsing-remitting multiple sclerosis, receiving a daily dose of 0.5 mg of fingolimod, presented with a two-month history of fever and unintended weight loss, accompanied by lymphadenopathy, splenomegaly, and lung involvement was investigated. Biopsy of a lung nodule revealed fungal structures suggestive of Histoplasma sp. Additionally, serological testing yielded positive for Histoplasma capsulatum. Disseminated histoplasmosis should be considered in the differential diagnosis of febrile syndromes in patients undergoing fingolimod therapy for multiple sclerosis, particularly in the Americas, where this mycosis is endemic. Treatment with itraconazole and modification of immunotherapy can achieve excellent clinical outcomes.

Epidemiological Assessment and Risk Factors for Mortality of Bloodstream Infections by Candida sp. and the Impact of the COVID-19 Pandemic Era.

Candidemia is one of the healthcare-associated infections that has high mortality. The risk factors that predispose a patient to develop this infection are mostly found in patients of greater severity and COVID-19 contributes to the risk of death. The aim of this study is to evaluate epidemiological characteristics and risk factors for mortality in patients with candidemia before and during the COVID-19 pandemic era. This is a retrospective study conducted at Instituto Central from 2016 to 2020 of patients with candidemia that were evaluated for demographic data, medical history, risk factors, microbiological data, therapeutic measures, complementary exams, device management, and outcome defined by 30-day mortality. A total of 170 episodes were included (58.2% males; mean age of 56 years). The overall incidence density of candidemia per 1000 admissions and per 1000 patient-days was 1.17 and 0.17, respectively, with an increase of 38% in the year 2020. The use of a central venous catheter was the most prevalent (93.5%) condition, followed by the previous use of antibiotics (91.1%). Corticosteroid use ranked seventh (56.4%). C. albicans was responsible for 71 (41.7%) of the isolates, followed by C. tropicalis and C. glabrata, with 34 (20%) isolates each. Echinocandin was prescribed in 60.1% of cases and fluconazole in 37%. Echocardiography resulted in six (5.08%) cases of endocarditis and fundoscopy resulting in two (2.4%) endophthalmitis. The 30-day mortality was 93/170 (54.7%). The risk factors associated with mortality were age (OR 1.03, CI 95% 1.01-1.06), heart disease (OR 7.51, CI 95% 1.48-37.9), hemodialysis (OR 3.68, CI 95% 1.28-10.57), and use of corticosteroids (OR 2.83, CI 95% 1.01-7.92). The COVID-19 pandemic had an impact on the increase incidence of candidemia. The persistently high mortality highlights the need for better management strategies, control of risk factors, and guarantee of adequate treatment.

Guideline Adherence and Outcomes of Patients with Candidemia in Brazil.

Candidemia is a significant cause of mortality among hospitalized patients, both worldwide and in Brazil. Prompt and appropriate treatment are essential to mitigate mortality, and clinical practice guidelines aim to optimize patient care based on the best scientific evidence. This study aims to examine the management of candidemia, assessing adherence to the guidelines of the Brazilian Society of Infectious Diseases in a single center located at São Paulo, Brazil. All adult patients hospitalized from 2016 to 2018 who presented one positive blood culture for Candida spp. were included. Electronic medical records were retrospectively reviewed to collect information relevant to the treatment for candidemia, in order to assess the adherence to the Brazilian guideline for the management of candidemia in relation to nine defined outcomes, and we correlated those findings with 30-day mortality by using uni- and multivariate analyses. A total of 115 patients were included; 68 patients (59.1%) were male, with a mean age of 55 years. C. albicans, C. tropicalis and C. glabrata were the most prevalent species. In total, 80 patients (69.5%) received antifungal treatment. The adherence to Brazilian guideline recommendations was determined as described in the following: initial treatment with echinocandin in 48 (60%); step-down to fluconazole in 21 (26.2%); collection of first control blood culture in 43 (58.9%); collection of second control blood culture, if the first one had been positive, in 14 (73.6%); treatment for 14 days after the first negative blood culture in 53 (65.4%); central venous catheter (CVC) removal in 66 (82.5%); CVC removal if the first control blood culture had been positive in 17 (89.4%); performance of a transthoracic echocardiogram in 51 (63.7%) and performance of a fundoscopy in 59 (73.7%). Univariate analysis showed that CVC removal and initial echinocandin therapy were more prevalent in the surviving group, but with no statistically significant difference. On the other hand, step-down to fluconazole demonstrated higher survival rate in the multivariate analysis OR 0.15 (95% CI 0.03-0.8); p = 0.02. The analysis of these nine recommendations demonstrates that it is necessary to improve adherence to specific recommendations and also disseminate strategies of the initial use of echinocandin as the drug of choice and addressing length of treatment and follow-up and complementary exams. Our study provides reassurance that the step-down to fluconazole is safe and may be recommended, if the preexisting conditions are present.

Paracoccidioidomycosis after eyebrow micropigmentation: Unusual reactivation or a new form of transmission by cutaneous inoculation?

We report a case of unusual paracoccidioidomycosis reactivation after eyebrow micropigmentation in a Brazilian patient. The cutaneous lesion was the only clinical manifestation. Direct cutaneous inoculation in dermal tissues with Paracoccidioides sp. is extremely rare, explaining why paracoccidioidomycosis is not classically considered a cutaneous implantation mycosis.

Clinical characteristics, diagnosis, and treatment of central nervous system sporotrichosis: Systematic review and meta-analysis.

BACKGROUND: The clinical features of central nervous system (CNS) sporotrichosis are derived from case reports and a limited series of cases. Our objective was to carry out a systematic review and meta-analysis of CNS sporotrichosis. METHODS: We searched PubMed/MEDLINE, Embase, Scopus, and LILACS on 9 September 2023. Our inclusion criteria were documentation of Sporothrix and demonstrated CNS involvement. A metaproportion or metamean analysis was performed to estimate a summary proportion with 95% confidence intervals. RESULTS: We included 52 cases of CNS sporotrichosis published from 1966 to 2023. Forty-six patients were male (88%, 95% CI: 77-95), and the mean age was 39 years (95% CI: 36-43). Close contact with cats was reported in 55% of cases (95% CI: 37-72). Thirty-two (61.5%) patients were from Brazil, 18 patients from the United State of America (34.6%). Only two Sporothrix species were reported: S. schenckii (26/41, 63%), and S. brasiliensis (15/41, 37%). The most common neurological symptom was headache. Meningitis was chronic in approximately 80% of cases. A significant majority of the patients were immunocompromised. HIV infection was the primary cause of immunosuppression (85%, 95% CI: 61-95). Overall mortality was 56% (22/39). The comparison of Kaplan-Meier survival curve showed a higher mortality with a statistically significant difference in immunosuppressed patients (p = .019). CONCLUSION: CNS sporotrichosis represents a notable cause of chronic meningitis, especially in individuals living in the Americas with HIV infection and concurrent skin lesions.

Effectiveness, Tolerability, and Safety of Different Amphotericin B Formulations in Invasive Fungal Infections: A Multicenter, Retrospective, Observational Study.

PURPOSE: Data on the real-life use of amphotericin B lipid complex (ABLC) compared with other available formulations are limited. This study aimed to evaluate the effectiveness, tolerability, and safety of different amphotericin B (AMB) intravenously administered in the context of hospital practice for the treatment of invasive fungal infections (IFI) and to provide new insights into the profile of ABLC. METHODS: This is a multicenter, retrospective, observational study conducted at 10 tertiary Brazilian hospitals. Patients first exposed to any formulation of AMB for treating endemic and opportunistic IFI who had received at least 2 intravenous doses were screened. Retrospective data (from January 2014 to December 2019) were extracted from the patients' medical records. Clinical parameters were examined pre- and post-treatment to determine effectiveness; acute infusion-related side effects (IRSE) and drug interruption to determine tolerability; and adverse events, toxicity, and treatment interruption were stated to analyze safety. FINDINGS: Overall, 1879 medical records of patients were identified. The median (interquartile rate) duration of treatment was 14 (7-21) days. The overall success rate (95% confidence interval [CI]) was 65% (95% CI 60-65). ABLC proved to be effective among AMB formulations with 59% (95% CI 55.6-62.5) within complete response. This was significantly higher in patients who received the drug for a longer period, ≥4 weeks compared to <1 week treatment (P < 0.001). IRSE was observed in 446 (23.7%) patients. Eight cases (1.4%) of severe IRSE in pediatrics and 14 (1.1%) in adults resulted in treatment discontinuation. Regarding safety, 637 (33.9%) patients presented some alteration in creatinine levels during AMB exposure, and 89 (4.74%) had to interrupt or discontinue the drug within the first 14 days of therapy because of renal dysfunction. Overall mortality was 34%. IMPLICATIONS: ABLC is an effective formulation for the treatment of invasive fungal infections, with few adverse events leading to drug discontinuation or lethal outcomes. Furthermore, this real-life study confirmed the comparative safety of AMB lipid formulations versus AMB deoxycholate.

Incomplete recovery of the CD4+/CD8+ ratio is associated with the late introduction of antiretroviral therapy among people living with HIV infection.

Despite being subject to lower AIDS-related mortality rates and having a higher life expectancy, patients with HIV are more prone to develop non-AIDS events. A low CD4+/CD8+ ratio during antiretroviral therapy identifies people with heightened immune senescence and increased risk of mortality. In clinical practice, finding determinants of a low CD4+/CD8+ ratio may be useful for identifying patients who require close monitoring due to an increased risk of comorbidities and death. We performed a prospective study on the evolution of the CD4+/CD8+ ratio in 60 patients infected with HIV (80% males), who were subjected to two different antiretroviral regimens: early and deferred therapy. The initial CD4+/CD8+ ratio was ≤1 for 70% of the patients in both groups. Older age, CD4+ cell count at inclusion, Nadir CD8+T-cell count, and Initial CD4+/CD8+ ratio ≤ 1 were risk factors for lack of ratio recovery. In the multivariate analysis, a CD4+/CD8+ ratio > 1 at the start of the treatment was found to be a determinant factor in maintaining a CD4+/CD8+ ratio > 1. The nadir CD4+T-cell count was lower in the deferred therapy group (p=0.004), and the last CD4+/CD8+ ratio ≤1 was not associated with comorbidities. Ratio recovery was not associated with the duration of HIV infection, time without therapy, or absence of AIDS incidence. A greater improvement was observed in patients treated early (p=0.003). In contrast, the slope of increase was slower in patients who deferred treatment. In conclusion, the increase in the CD4+/CD8+ ratio occurred mostly for patients undergoing early strategy treatment and its extension did not seem to be related to previous HIV-related factors.

Histoplasmosis in a fingolimod-treated patient: case report and scoping review

ABSTRACT Fingolimod is a sphingosine-1-phosphate receptor modulator used to treat multiple sclerosis. While fingolimod has been associated with an increased risk of cryptococcal meningitis, its correlation with other deep mycoses remains unclear. In this study, we conducted a scoping review of fingolimod associated with histoplasmosis, based on a case report, a literature review, and data from the FDA Adverse Events Reporting System (FAERS) as of January 24th, 2023. A 30-year-old Brazilian woman diagnosed with relapsing-remitting multiple sclerosis, receiving a daily dose of 0.5 mg of fingolimod, presented with a two-month history of fever and unintended weight loss, accompanied by lymphadenopathy, splenomegaly, and lung involvement was investigated. Biopsy of a lung nodule revealed fungal structures suggestive of Histoplasma sp. Additionally, serological testing yielded positive for Histoplasma capsulatum. Disseminated histoplasmosis should be considered in the differential diagnosis of febrile syndromes in patients undergoing fingolimod therapy for multiple sclerosis, particularly in the Americas, where this mycosis is endemic. Treatment with itraconazole and modification of immunotherapy can achieve excellent clinical outcomes.

Clinical and immunological features of laryngeal cryptococcosis

ABSTRACT The literature holds few descriptions on immune response findings for laryngeal cryptococcosis. Immunology has been more extensively described in cases involving the central nervous system and the lungs, although many of these studies were conducted in animal models. We aimed to analyze the clinical and immunological characteristics of three patients with laryngeal cryptococcosis. We observed a weak participation of the innate immune response, whereas adaptive immunity showed the predominance of a Th2-type response over a Th1-type response. Most cases occur in male older adults with immunosuppressive conditions, of which HIV infection was absent. Hoarseness configured the main symptom. We found a disease that was restricted to the larynx and possibly the lungs by contiguity. Patients with hoarseness and lesions in nasal endoscopy should be investigated for cryptococcosis by a biopsy of the larynx, including with negative serum cryptococcal antigen. The immunological aspects of our findings of laryngeal involvement resembled those in the most commonly affected systems.

Cutaneous Naganishia albida (Cryptococcus albidus) infection: a case report and literature review.

Naganishia albida (Cryptococcus albidus) is considered saprophytic fungi, and is rarely reported as a human pathogen. Cutaneous infections caused by non-neoformans cryptococcus are rare. We describe a case of an immunocompetent older male with cutaneous cryptococcosis caused by Naganishia albida following skin trauma, and conduct a literature review in PubMed, Lilacs, and Embase. Only six previous similar reports were found. The seven cases (including ours) were widely distributed geographically (Brazil, the US, the UK, Hungary, South Korea, and Iran), all males, and their ages varied, ranging from 14 to 86 years. Four individuals had underlying skin diseases (Sezary Syndrome, psoriasis, and skin rash without etiology) plus potentially immunosuppressive underlying conditions (diabetes mellitus, kidney transplantation, and the use of etanercept, adalimumab, and methylprednisolone). Cutaneous presentation was polymorphic, with lesions characterized as warts, ulcers, plaques, and even macules. Two patients presented disseminated disease. Serum cryptococcal antigen was negative in six patients, and diagnosis was made by fungal culture in all. There is a lack of data on optimal antifungal treatment and outcomes.

Itraconazole Serum Trough Concentrations Using Oral Capsules for the Treatment of Chronic Pulmonary Aspergillosis: What is the Target?

BACKGROUND: In regions where there is only itraconazole capsule as a therapeutic option for treatment of chronic pulmonary aspergillosis (CPA), measuring the serum concentrations becomes even more important for therapeutic success. OBJECTIVE: Evaluate the initial itraconazole serum trough concentrations after the administration of oral capsule of itraconazole for the treatment of CPA. METHODS: The measurement was performed at least 7-days after initiation of therapy. The standard treatment at our institution was a 200 mg capsule every 12 h. We defined that an adequate serum trough concentration of itraconazole during treatment was 1-4 mg/L. RESULTS: This study recruited 28 patients. The median value was 0.30 mg/L (IQR 0.01-0.70). Only 11% (n = 3) had adequate serum concentrations based on guideline recommendation. All patients with clinical deterioration had itraconazole serum levels ≤ 0.8 mg/L. CONCLUSION: The initial serum concentrations of itraconazole after capsule formulation administration were low. Increasing the dose should be considered when the itraconazole concentration is low, especially if it is ≤ 0.8 mg/L, and the patient presents with clinical deterioration. Larger studies are needed to evaluate the adequate concentrations recommended for CPA.

Systematic review and meta-analysis of galactomannan antigen testing in serum and bronchoalveolar lavage for the diagnosis of chronic pulmonary aspergillosis: defining a cutoff.

BACKGROUND: A clear cutoff value of galactomannan (GM) has not been established for chronic pulmonary aspergillosis (CPA) and is frequently extrapolated from invasive pulmonary aspergillosis. We performed a systematic review and meta-analysis to evaluate the diagnostic performance of serum and bronchoalveolar lavage (BAL) GM, and to propose a cutoff. METHODS: We extracted from the studies the cutoff of serum or/and BAL GM associated with true positives, false positives, true negatives, and false negatives. We performed a multi-cutoff model and a non-parametric random effect model. We estimated the optimal cutoff and the area under the curve (AUC) for GM in serum and BAL samples. RESULTS: Nine studies from 1999 to 2021 were included. Overall, the optimal cutoff of serum GM was 0.96 with a sensitivity of 0.29 (95%CI: 0.14-0.51); specificity of 0.88 (95%CI: 0.73-0.95); and AUC of 0.529 (with a CI: [0.415-0.682] [0.307-0.713]). The AUC for the non-parametric ROC model was 0.631. For BAL GM the cutoff was 0.67 with a sensitivity of 0.68 (95%CI: 0.51-0.82), specificity of 0.84 (95%CI: 0.70-0.92), and AUC of 0.814 (with a CI: [0.696-0.895] [0.733-0.881]). The AUC for the non-parametric model was 0.789. CONCLUSION: The diagnosis of CPA requires the assessment of a combination of mycological and serological factors, as no single serum and/or BAL GM antigen test is adequate. BAL GM performed better than serum, with better sensitivity and excellent accuracy.

Clinical, radiological and laboratory characteristics of central nervous system histoplasmosis: A systematic review of a severe disease.

BACKGROUND: The knowledge of central nervous system (CNS) histoplasmosis is limited to case reports and series. OBJECTIVES: Our objective was to synthesise clinical, radiological and laboratory characteristics of CNS histoplasmosis to improve our understanding of this rare disease. METHODS: We performed a systematic review using Pubmed/MEDLINE, Embase and LILACS databases accessed on March 2023 without publication date restrictions. Inclusion criteria comprised: (1) histopathological, microbiological, antigen or serological evidence of histoplasmosis; (2) CNS involvement based on cerebrospinal fluid pleocytosis or neuroimaging abnormalities. We classified the certainty of the diagnosis in proven (CNS microbiological and histopathological confirmation), probable (CNS serological and antigen confirmation) or possible (non-CNS evidence of histoplasmosis). Metaproportion was used to provide a summary measure with 95% confidence intervals for the clinical, radiological and laboratory characteristics. Chi-squared test was used to compare mortality between pairs of antifungal drugs. RESULTS: We included 108 studies with 298 patients. The median age was 31 years, predominantly male, and only 23% were immunocompromised (134/276, 95%CI: 3-71), mainly due to HIV infection. The most common CNS symptom was headache (130/236, 55%, 95%CI: 49-61), with a duration predominantly of weeks or months. Radiological presentation included histoplasmoma (79/185, 34%, 95%CI: 14-61), meningitis (29/185, 14%, 95%CI: 7-25), hydrocephalus (41/185, 37%, 95%CI: 7-83) and vasculitis (18/185, 6%, 95%CI: 1-22). There were 124 proven cases, 112 probable cases and 40 possible cases. The majority of patients presented positive results in CNS pathology (90%), serology (CSF: 72%; serum: 70%) or CSF antigen (74%). Mortality was high (28%, 56/198), but lower in patients who used liposomal amphotericin B and itraconazole. Relapse occurred in 13% (23/179), particularly in HIV patients, but less frequently in patients who used itraconazole. CONCLUSION: Central nervous system histoplasmosis usually presents subacute-to-chronic symptoms in young adults. Neuroimaging patterns included not only focal lesions but also hydrocephalus, meningitis and vasculitis. Positive results were commonly found in CSF antigen and serology. Mortality was high, and treatment with liposomal amphotericin B followed by itraconazole may decrease mortality.

Characteristics, mortality, associated variables with death, and therapeutic response among HIV-positive, solid organ transplant (SOT), and non-HIV-positive/non-transplant (NHNT) patients with cryptococcosis: First multicenter cohort study in Brazil.

Cryptococcosis is traditionally associated with immunocompromised patients but is increasingly being identified in those without the human immunodeficiency virus (HIV) or other immunocompetent individuals. We aim to describe the characteristics, mortality, and associated variables with death among hospitalized patients with cryptococcosis in Brazil. This is the first multicenter retrospective cohort study conducted in seven public tertiary Brazilian hospitals. A total of 384 patients were included; the median age was 39 years and 283 (73.7%) were men. In all, 304 HIV-positive were hosts (79.2%), 16 (4.2%) solid organ transplant (SOT), and 64 (16.7%) non-HIV-positive/non-transplant (NHNT). Central nervous system (CNS) cryptococcosis had a significantly higher number across disease categories, with 313 cases (81.5%). A total of 271 (70.6%) patients were discharged and 113 (29.4%) died during hospitalization. In-hospital mortality among HIV-positive, SOT, and NHNT was 30.3% (92/304), 12.5% (2/16), and 29.7% (19/64), respectively. Induction therapy with conventional amphotericin B (AMB) mainly in combination with fluconazole (234; 84.2%) was the most used. Only 80 (22.3%) patients received an AMB lipid formulation: liposomal (n = 35) and lipid complex (n = 45). Most patients who died belong to the CNS cryptococcosis category (83/113; 73.4%) when compared with the others (P = .017). Multivariate analysis showed that age and disseminated cryptococcosis had a higher risk of death (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.01-1.05; P = .008 and OR, 1.84; 95% CI, 1.01-3.53; P = .048, respectively). Understanding the epidemiology of cryptococcosis in our settings will help to recognize the burden and causes of mortality and identify strategies to improve this scenario.

This multicenter cohort study included 384 hospitalized individuals with cryptococcosis in Brazil. Most individuals were men (74%), HIV-positive (79%), had central nervous system involvement (82%), and received conventional amphotericin plus fluconazole (84%). In-hospital mortality was high (29%).

Challenges, Characteristics, and Outcomes of Chronic Pulmonary Aspergillosis: A 11-Year Experience in A Middle-Income Country.

OBJECTIVES: Chronic pulmonary aspergillosis (CPA) is a research priority in fungal diseases with a need for new studies to reduce misdiagnosis with more common diseases, discuss improvement in diagnostic methods and better characterize gaps in antifungal and surgical treatments to improve clinical outcomes. METHODS: In this retrospective study, we reviewed medical records of patients diagnosed with CPA from January 2010 to June 2021 at University of São Paulo, São Paulo, Brazil. We evaluated clinical characteristics, radiological findings, serology, treatment, and outcomes. RESULTS: The study included 91 participants, with 43 (47.3%) patients who underwent surgery and 69 (75.8%) received antifungal therapy. We found a predominance of middle-aged adults (median 51 years), males (n = 58, 64%) with lower BMI (median 21.3 kg/m2). The most common underlying lung disease was pulmonary tuberculosis (n = 70, 76.9%). The commonest symptoms were cough (n = 67, 74%), haemoptysis, and dyspnea (n = 63, 70%). The most common chest computerized tomography abnormalities were cavity (n = 86, 94.5%), with a predominance of mycetomas (n = 78, 91%). The serology was positive in 81% (61/75). The one-year mortality was low (3.3%). Clinical improvement and stability occurred in 89% of participants for constitucional symptoms and 86% for pulmonary symptoms. While serological improvement and stability occurred in 71%. Radiological improvement and stability occurred in 75%. CONCLUSION: We observed a good outcome after 1-year follow-up, in which the majority had improvement or stability of pulmonary and constitutional symptoms, decrease in CIE titers and low mortality.
