    Antifungal stewardship: The Latin American experience
    (2023) RIERA, F.; LUNA, J. Cortes; RABAGLIATTI, R.; SCAPELLATO, P.; CAEIRO, J. P.; MAGRI, M. M. Chaves; SOTOMAYOR, C. E.; FALCI, D. Rodrigues
    Antifungal stewardship is a critical component of healthcare management that focuses on optimizing the use of antifungal medications to improve patient outcomes, minimize resistance, and reduce healthcare costs. In resource-limited settings, the prevalence of fungal infections remains a significant health concern, often exacerbated by factors such as compromised immune systems, inadequate diagnostic capabilities, and limited access to antifungal agents. This paper reviews the current state of antifungal stewardship practices in developing countries, addressing the unique socioeconomic and healthcare landscape.

    (2023) VANNI, Tazio; SALOMAO, Maria da Grada; VISCONDI, Juliana Yukari Kodaira; BRAGA, Patricia Emilia; SILVA, Anderson da; PIORELLI, Roberta de Oliveira; SANTOS, Joane do Prado; GATTAS, Vera Lucia; LUCCHESI, Maria Beatriz Bastos; OLIVEIRA, Mayra Martho Moura de; KOIKE, Marcelo Eiji; CAMPOS, Lucia M. A.; COELHO, Eduardo B.; WECKX, Lily Yin; LARA, Amanda Nazareth; PAIVA, Terezinha M.; TIMENETSKY, Maria do Carmo S. T.; PRECIOSO, Alexander Roberto
    Background: To enhance the production and availability of influenza vaccines in different regions of the world is paramount to mitigate the global burden of this disease. Instituto Butantan developed and man-ufactured an embryonated egg-based inactivated split-virion trivalent seasonal influenza vaccine as part of a technology transfer partnership with Sanofi Pasteur.Methods: This is a phase IV, randomized, double-blind, active-controlled, multicenter clinical trial includ-ing adults 18-60 and > 60 years recruited during the 2019 southern hemisphere influenza season. Subjects were randomized 1:1 to receive either the Sanofi Pasteur Trivalent Seasonal Influenza Vaccine (SP-TIV) or Instituto Butantan Trivalent Seasonal Influenza Vaccine (IB-TIV). Hemagglutinin inhibition antibody titers were assessed pre-vaccination and 21 days post-vaccination.Results: 624 participants were randomized and vaccinated. In both intention-to-treat and per-protocol analysis, non-inferiority of the SP-TIV versus IB-TIV was demonstrated for the three influenza strains. In the per-protocol analysis, the SP-GMT/IB-GMT ratios for H1N1, H3N2, and B were 0.9 (95%CI, 0.7- 1.1), 1.2 (95%CI, 1.0-1.4), and 1.1 (95%CI, 0.9-1.3), respectively. Across vaccination groups, the most com-mon adverse reactions (AR) were limited to the injection-site, including pain and tenderness. The major-ity of the ARs were graded 1 and/or 2 and lasted less than one day. No serious adverse reaction was observed.Conclusion: This study demonstrated the non-inferiority of the immunogenicity of a single-dose of Instituto Butantan versus a single dose of the Sanofi Pasteur Seasonal Trivalent Influenza Vaccine in adults. Both vaccines were well tolerated and presented similar safety profiles.(c) 2023 Elsevier Ltd. All rights reserved.

    Finger-Prick Whole Blood Cryptococcal Antigen Lateral Flow Assay for the Diagnosis of Cryptococcosis in HIV-Negative Patients: A Case Series Study in Two Tertiary Centers in São Paulo, Brazil
    (2023) VIDAL, Jose E.; OLIVEIRA, Fernanda Gurgel; VIEIRA, Marcela; PEREIRA, Luisa; LUCAS JUNIOR, Rodovaldo M.; GUEDES, Bruno Fukelman; MAGRI, Marcello Chaves; BOULWARE, David R.
    Cryptococcosis in HIV-negative patients can be an opportunistic or endemic disease. There are no published studies on the use of the finger-prick whole blood (point-of-care) cryptococcal antigen lateral flow assay (CrAg LFA) for diagnosing cryptococcosis in HIV-negative patients. We conducted a case series study of HIV-negative patients with cryptococcosis in two centers in S & atilde;o Paulo, Brazil. The objectives were to identify the sensitivity of a finger-prick whole blood CrAg LFA and to describe the main characteristics of this population. We identified 30 HIV-negative patients with cryptococcosis [19 (63%), male; median age, 47 years]. Ten (33%) patients were immunosuppressed, ten (33%) had other comorbidities, and ten (33%) were apparently immunocompetent and without comorbidities. The distribution of the sites of cryptococcosis was as follows: the central nervous system, 90% (n = 27); pulmonary, 43% (n = 13); and other extrapulmonary sites, 40% (n = 12). The sensitivity of the finger-prick whole blood CrAg LFA for the diagnosis of cryptococcosis was 97% (29/30). Among 26 participants with cryptococcal meningitis, the sensitivity of testing cerebrospinal fluid was as follows: CrAg latex agglutination, 77% (20/26); CrAg LFA, 96% (25/26); and culture, 81% (21/26). Culture speciation identified Cryptococcus gattii in 16 (62%) cases, and all had a positive finger-prick whole blood CrAg LFA. This test presented high sensitivity to the diagnosis of cryptococcosis in HIV-negative patients, including those caused by C. gattii.

    Hemoperitoneum after a Bothrops snakebite: Case report
    (2024) RIBEIRO, Adriana Baqueiro Abad; SANTORO, Marcelo Larami; DUARTE, Marcelo Ribeiro; VIRGULINO, Cristiana Cruz; OLIVEIRA, Gerson Sobrinho Salvador de; FRANCA, Francisco Oscar de Siqueira
    Snakebites are frequent in tropical countries. Brazil has an average of 27,000 cases per year, with a fatality rate of 0.5%, and the Bothrops genus is the most common causative agent, accounting for about 70-90% of the accidents. This report describes a case of human envenomation by a juvenile Bothrops jararaca snake in Sa similar to o Paulo, Brazil, in a 71 years-old man, previously healthy. He presented a life-threatening envenomation, which developed to severe hypotension, acute kidney injury and extensive peritoneal hemorrhage. The hemoperitoneum was diagnosed due to persistent hypotension associated with anemia, pain and gastrointestinal complaints. Abdominal Computed Tomography scans showed a moderate to large amount of presumable hematic material inside the abdominal cavity, predominantly in the perihepatic and perisplenic spaces. The intra-abdominal hemorrhage was not surgically addressed, and the patient was discharged 5 days after hospitalization, with the progressive absorption of the hemoperitoneum. Systemic bleeding is one of the complications and main causes of death in Bothrops envenomations. Acute peritoneal hemorrhage is one of these serious complications that must be carefully addressed since its management must take into account the risk of bleeding caused by toxins that affect hemostasis. The case described highlights the importance of early diagnosis and adequate management of this potentially fatal complication in snakebites.

    Cutaneous Naganishia albida (Cryptococcus albidus) infection: a case report and literature review
    (2023) OLIVEIRA, Vitor Falcao de; FUNARI, Alexandre Pereira; TABORDA, Mariane; MAGRI, Adriana Satie Goncalves Kono; LEVIN, Anna Sara; MAGRI, Marcello Mihailenko Chaves
    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.

    New Allele-Specific Oligonucleotide (ASO) amplifications for Toxoplasma gondii rop18 allele typing: Analysis of 86 human congenital infections in Brazil
    (2023) SANTOS, Emilly Henrique dos; BARREIRA, Gabriel Acca; YAMAMOTO, Lidia; ROCHA, Mussya Cisotto; RODRIGUES, Karen Alessandra; CRUZ, Maria Carolina Pires; KANUNFRE, Kelly Aparecida; OKAY, Thelma Suely
    This study aimed to detect and differentiate Toxoplasma gondii by the allele typing of its polymorphic rop18 gene. For this purpose, a novel genotyping system using allele-specific oligonucleotides (ASOs) was designed, consisting of three ASO pairs. The first and third pairs specifically amplify rop18 allele I and allele III, while the second pair amplify both allele I and II. Genomic DNA from 86 congenital infections was analyzed by ASO-PCRs, successfully typing 82 (95.35%) samples. The remaining 4 samples (4.65%) required sequencing and single nucleotide polymorphism (SNP) analysis of the amplification products. The distribution of samples according to rop18 alleles was: 39.5% of allele III, 38.4% of allele II, 19.8% of mixed rop18 alleles (I/III or II/III), and 2.3% of allele I. The six severely compromised infants exhibited the highest parasite load levels and were infected during the first and early second trimesters of pregnancy. Among these cases, two were associated with rop18 allele I parasites, two with mixed rop18 alleles (I/III), one with allele II, and one with allele III parasites. In conclusion, all severe cases of congenital toxoplasmosis were infected during early pregnancy, but they were not exclusively associated with rop18 allele I parasites, as observed in murine toxoplasmosis. Furthermore, nearly one-fifth of parasites were non-archetypal, exhibiting more than one rop18 allele, indicating a higher genetic diversity of Toxoplasma gondii in this South American sample. Overall, a robust T. gondii rop18 allele typing was developed and suggested that congenital toxoplasmosis in humans involves complex mechanisms beyond the parasite genotype.

    Safety and immunogenicity of influenza A(H3N2) component vaccine in juvenile systemic lupus erythematosus
    (2023) AIKAWA, Nadia Emi; BORBA, Eduardo Ferreira; BALBI, Verena Andrade; SALLUM, Adriana Maluf Elias; BUSCATTI, Izabel Mantovani; CAMPOS, Lucia Maria Arruda; KOZU, Katia Tomie; GARCIA, Cristiana Couto; CAPAO, Artur Silva Vidal; PROENCA, Adriana Coracini Tonacio de; LEON, Elaine Pires; DUARTE, Alberto Jose da Silva; LOPES, Marta Heloisa; SILVA, Clovis Artur; BONFA, Eloisa
    Introduction Seasonal influenza A (H3N2) virus is an important cause of morbidity and mortality in the last 50 years in population that is greater than the impact of H1N1. Data assessing immunogenicity and safety of this virus component in juvenile systemic lupus erythematosus (JSLE) is lacking in the literature.Objective To evaluate short-term immunogenicity and safety of influenza A/Singapore (H3N2) vaccine in JSLE.Methods 24 consecutive JSLE patients and 29 healthy controls (HC) were vaccinated with influenza A/Singapore/INFIMH-16-0019/2016(H3N2)-like virus. Influenza A (H3N2) seroprotection (SP), seroconversion (SC), geometric mean titers (GMT), factor increase in GMT (FI-GMT) titers were assessed before and 4 weeks post-vaccination. Disease activity, therapies and adverse events (AE) were also evaluated.Results JSLE patients and controls were comparable in current age [14.5 (10.1-18.3) vs. 14 (9-18.4) years, p = 0.448] and female sex [21 (87.5%) vs. 19 (65.5%), p = 0.108]. Before vaccination, JSLE and HC had comparable SP rates [22 (91.7%) vs. 25 (86.2%), p = 0.678] and GMT titers [102.3 (95% CI 75.0-139.4) vs. 109.6 (95% CI 68.2-176.2), p = 0.231]. At D30, JSLE and HC had similar immune response, since no differences were observed in SP [24 (100%) vs. 28 (96.6%), p = 1.000)], SC [4 (16.7%) vs. 9 (31.0%), p = 0.338), GMT [162.3 (132.9-198.3) vs. 208.1 (150.5-287.8), p = 0.143] and factor increase in GMT [1.6 (1.2-2.1) vs. 1.9 (1.4-2.5), p = 0.574]. SLEDAI-2K scores [2 (0-17) vs. 2 (0-17), p = 0.765] and therapies remained stable throughout the study. Further analysis of possible factors influencing vaccine immune response among JSLE patients demonstrated similar GMT between patients with SLEDAI < 4 compared to SLEDAI >= 4 (p = 0.713), as well as between patients with and without current use of prednisone (p = 0.420), azathioprine (p = 1.0), mycophenolate mofetil (p = 0.185), and methotrexate (p = 0.095). No serious AE were reported in both groups and most of them were asymptomatic (58.3% vs. 44.8%, p = 0.958). Local and systemic AE were alike in both groups (p > 0.05).Conclusion This is the first study that identified adequate immune protection against H3N2-influenza strain with additional vaccine-induced increment of immune response and an adequate safety profile in JSLE.

    Systematic review and meta-analysis of galactomannan antigen testing in serum and bronchoalveolar lavage for the diagnosis of chronic pulmonary aspergillosis: defining a cutoff
    (2023) OLIVEIRA, Vitor Falcao de; SILVA, Guilherme Diogo; TABORDA, Mariane; LEVIN, Anna S.; MAGRI, Marcello Mihailenko Chaves
    BackgroundA 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.MethodsWe 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.ResultsNine 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.ConclusionThe 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.

    Robust immunogenicity to the H3N2 component of influenza A vaccine in primary Sjogren syndrome
    (2023) PASOTO, Sandra Gofinet; BORBA, Eduardo Ferreira; FORMIGA, Francisco Fellipe Claudino; PEDROSA, Tatiana do Nascimento; AIKAWA, Nadia Emi; SIQUEIRA, Marilda Agudo Mendonca Teixeira de; CAPAO, Artur Silva Vidal; PROENCA, Adriana Coracini Tonacio de; FULLER, Ricardo; YUKI, Emily Figueiredo Neves; LEON, Elaine Pires; MARTINS, Victor Adriano de Oliveira; LOPES, Marta Heloisa; DUARTE, Alberto Jose da Silva; SILVA, Clovis Artur Almeida da; BONFA, Eloisa
    Introduction Influenza A (H3N2) virus is the major cause of morbidity/mortality due to seasonal influenza over 50 years. Data about the safety/immunogenicity of influenza A/Singapore (H3N2) vaccine are scarce in primary Sjogren syndrome (pSS). Methods Twenty-one consecutive pSS patients and 42 HC (healthy control individuals) were immunized with influenza A/Singapore/INFIMH-16-0019/2016 (H3N2)-like virus. Rates of SP (seroprotection) and SC (seroconversion), GMT (geometric mean titers), FI-GMT (factor increase in GMT), ESSDAI (EULAR Sjogren's Syndrome Disease Activity Index), and adverse events were appraised before and 4 weeks post-vaccination. Results pSS and HC had similar mean age (51.2 +/- 14.2 vs. 50.6 +/- 12.1 years, p =0.886). Pre-vaccination SP rates were high in pSS and HC (90.5% vs. 71.4%, p =0.114), and GMT were higher in pSS [80.0 (52.4-160.0) vs. 40.0 (20.0-80.0), p =0.001]. The percentage of influenza vaccination in the preceding two years was elevated and similar in pSS and HC (94.1% vs. 94.6%, p = 1.000). GMT values augmented in both groups four weeks after vaccination and persisted higher in the first group [160.0 (80.0-320.0) vs. 80.0 (40.0-80.0), p< 0.001] with equivalent FI-GMT [1.4 (1.0-2.8) vs. 1.4 (1.0-2.0), p = 0.410]. Both groups had low and similar SC rates (19.0% vs. 9.5%, p = 0.423). ESSDAI values persisted steadily during the study (p = 0.313). No serious adverse events have occurred. Conclusion The novel demonstration that the influenza A/Singapore (H3N2) vaccine induces a different pattern of immunogenicity from other influenza A constituents in pSS, featured by a desirable high pre- and post-vaccination immunogenicity, is in line with reported differences in immune responses between strains in trivalent vaccines and may be related to pre-existing immunity. #NCT03540823.

    Usefulness of PCR for Trypanosoma cruzi DNA in blood and endomyocardial biopsies for detection of Chagas disease reactivation after heart transplantation: A comparative study
    Background: Chagas disease reactivation (CDR) after heart transplantation is characterized by relapse of the infectious disease with proliferation and dissemination of Trypanosoma cruzi parasites. Serial blood PCR testing is consensually recommended for CDR monitoring, but there is uncertainty about the incremental value in performing the molecular tests in endomyocardial biopsies (EMB). Methods: We compared qualitative and quantitative results of PCR for T cruzi DNA in 62 pairs of blood and EMB collected with a maximum time interval of 7 days, from 34 heart-transplanted, chagasic patients. Results: Blood PCR resulted positive in 39/62 (62.9%) samples, with PL ranging from 0.14 to 1610.73 (median: 3.31). PCR resulted positive in 8/60 (13.3%) EMB, with PL ranging from 2.82 to 1670.55 (median: 65.63). All blood samples which tested negative presented a paired EMB which also tested negative. However, 31/39 (79.5%) blood samples which tested positive presented a paired EMB which tested negative. There was poor agreement between blood and EMB PCR (kappa = 0.153). CDR affecting the myocardium (myo-CDR) was diagnosed in three occasions. PCR resulted positive in both blood and EMB at the time of myo-CDR, with PL ranging from 0.61 to 1610.73 in blood and 13.8 to 1670.55 in EMB. Conclusions: Negative PCR for T cruzi in blood rules out myo-CDR, with no value of testing EMB. Positive PCR in blood with high PL is diagnostic for myo-CDR. If PCR in blood results positive with low PL, testing EMB is useful: negative PCR turns unlikely, and positive PCR reinforces greatly the possibility of myo-CDR. © 2021 Wiley Periodicals LLC

    The methodological quality of economic evaluations of measles outbreaks: A systematic review of cost-of-illness studies
    (2023) SOAREZ, Patricia Coelho de; ROZMANA, Luciana Martins; FONSECA, Taiane Siraisi; BORSARI, Pietro Rodrigo; PERCIO, Jadher; BARRERA, Lely Stella Guzman; SARTORI, Ana Marli Christovam
    Objectives: To identify the main cost components included in the economic evaivations of measles outbreaks, their items and cost drivers, and evaluate the quality of costing methodology, analyzing the key features that may affect the validity of these studies in countries with different income leveis Methods: We systematically searched multiple databases EMBASE, MEDLINE (via PubMed), Biblioteca Virtual em Saude do Ministerio da Saude (BVS MS), NHS Economic Evaluation Database (NHS EED) and NHS Health Technology Assessment (NHS HTA) (via The Centre for Reviews and Dissemination Library - CRD), and EconLit, SCOPUS, and Web of Science, selecting cost analysis and cost of illness studies (COI) of measles outbreaks. Two independent reviewers screened articles for relevance and extracted the data. The quality of costing methods was assessed using a guide to critical evaluation of COI studies. We performed a qualitative narrative synthesis. Results: Twenty-two studies were reviewed. Most studies evaluated outbreaks that occurred from 2011 to 2013 and 2017 to 2019. Total costs varied from $40,147 to $39.3 million. Per case cost varied from $168 to $49,439. The main drivers of measles outbreak costs were outbreak response, personnel, and productivity losses. Most studies (20/22) did not report the costing methodology adonted, the degree of disaggregation used in the identification and measurement of resource and costs components and the method for the valuation of resource and cost components. Conclusions: The quality of the costing methodology, its transparency and accuracy are essential to the validity of these studies results and their potential use to allocate public health resources in the most efficient manner and to inform measles outbreak control strategies, with rapid and effective response.

    Risk factors for reduction in adherence to protective measures following coronavirus disease 2019 (COVID-19) vaccination and vaccine perceptions among healthcare workers, in Sao Paulo, Brazil
    (2023) LOPEZ, Andres Mello; BORGES, Igor Carmo; LUNA-MUSCHI, Alessandra; PERES, Carlos Henrique Mesquita; CARRENO, Paolo Gripp; OLIVEIRA, Arthur Magalhaes de; ALMEIDA, Humberto Bertola Siqueira de; MARQUES, Vivian Helena de Castro; CORCHS, Felipe; LEVIN, Anna Sara; COSTA, Silvia Figueiredo; SARTORI, Ana Marli Christovam
    A survey evaluated 2,300 healthcare workers following the first dose of a coronavirus disease 2019 (COVID-19) vaccine in a tertiary-quaternary hospital in Sao Paulo, Brazil. Adherence to protective measures following vaccination was compared to previous non-work-related behaviors. Younger age, previous COVID-19, and burnout symptoms were associated with reduced adherence to mitigation measures.

    Performance of a Real-Time PCR Assay for the Detection of Five Candida Species in Blood Samples from ICU Patients at Risk of Candidemia
    (2023) FELIX, Gabriel N.; FREITAS, Vera L. T. de; SILVA JUNIOR, Afonso R. da; MAGRI, Marcello M. C.; ROSSI, Flavia; SEJAS, Odeli N. E.; ABDALA, Edson; MALBOUISSON, Luiz M. S.; GUIMARAES, Thais; BENARD, Gil; NEGRO, Gilda M. B. Del
    The gold standard for diagnosing invasive candidiasis still relies on blood cultures, which are inefficient and time-consuming to analyze. We developed an in-house qPCR assay to identify the 5 major Candida species in 78 peripheral blood (PB) samples from ICU patients at risk of candidemia. Blood cultures and (1,3)-beta-D-glucan (BDG) testing were performed concurrently to evaluate the performance of the qPCR. The qPCR was positive for DNA samples from all 20 patients with proven candidemia (positive PB cultures), showing complete concordance with Candida species identification in blood cultures, except for detection of dual candidemia in 4 patients, which was missed by blood cultures. Additionally, the qPCR detected Candida species in six DNA samples from patients with positive central venous catheters blood (CB) but negative PB cultures. BDG values were similarly high in these six samples and the ones with proven candidemia, strongly suggesting the diagnosis of a true candidemia episode despite the negative PB cultures. Samples from patients neither infected nor colonized yielded negative results in both the qPCR and BDG testing. Our qPCR assay was at least as sensitive as blood cultures, but with a shorter turnaround time. Furthermore, negative results from the qPCR provided strong evidence for the absence of candidemia caused by the five major Candida species.

    Clinical, radiological and laboratory characteristics of central nervous system histoplasmosis: A systematic review of a severe disease
    (2023) OLIVEIRA, Vitor Falcao de; KRUSCHEWSKY, Wdson Luis Lima; SEKIGUCHI, William Kazunori; COSTA, Silvia F. F.; LEVIN, Anna S. S.; MAGRI, Marcello Mihailenko Chaves; SILVA, Guilherme Diogo
    BackgroundThe knowledge of central nervous system (CNS) histoplasmosis is limited to case reports and series. ObjectivesOur objective was to synthesise clinical, radiological and laboratory characteristics of CNS histoplasmosis to improve our understanding of this rare disease. MethodsWe 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. ResultsWe 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. ConclusionCentral 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.

    Background: Sporotrichosis is an endemic subcutaneous mycosis classically caused by the Sporothrix schenckii species complex. Recently, sporotrichosis has emerged in Brazil as a cat-transmitted epidemic caused by a new species, Sporothrix brasiliensis. Objectives: To survey the clinical-epidemiological profile of all sporotrichosis cases diagnosed between 2011 and 2020 at a reference hospital in Sao Paulo metropolitan area and evaluate the annual distribution of cases in relation to seasonality. Methods: Patients' demographic and clinical-epidemiological data were surveyed. A generalized linear model was fitted to relate the quarterly number of sporotrichosis cases detected between 2015 and 2019 with precipitation and temperature series. Prediction of the number of cases from 2011 to 2014 was attempted based on the fitted model without the trend component that appears from 2015. Results: Among 271 suspected cases admitted during 2011-2020, 254 were confirmed by fungal isolation and/or clinical-epidemiological criteria. We observed that 2015 onwards the number of cases regularly increased during Autumn and Winter, the driest and coldest stations of the year. We verified that temperature series affected the number of cases (p = .005) because an increase of 1 degrees C in the temperature series was associated with a 14.24% decrease in the average cases number, with the average number of cases increasing by 10.96% (p < .0001) every quarter, corresponding to an annual increase of 52%. Between 2011 and 2014, the predicted number of sporotrichosis cases averaged 10-12 per year, with 33%-38% occurring in the winter. Conclusion: We hypothesize that sporotrichosis seasonality is associated with the felines' oestrus cycle, which may provide alternative, cat-directed approaches to the sporotrichosis epidemic control.

    Candidemia remains a major public health challenge due to its high mortality rates, especially in developing countries. Monitoring epidemiological trends may provide insights for better clinical outcomes. This study aimed to describe trends in the epidemiology, therapeutic practices, and mortality in candidemia through a retrospective comparative analysis between two surveillance cohorts of all candidemic adults at eleven tertiary hospitals in Brazil, from 2010-2011 (Period I) versus 2017-2018 (Period II). A total of 616 cases were diagnosed, with 247 being from Period II. These patients were more likely to have three or more coexisting comorbidities [72 (29.1%) vs. 60 (16.3%), p < 0.001], had a prior history of in-hospital admissions more often [102 (40.3%) vs. 79 (21.4%), p = 0.001], and presented with candidemia earlier after admission, within 15 days (0-328) vs. 19 (0-188), p = 0.01. Echinocandins were more frequently prescribed [102 (41.3%) vs. 50 (13.6%), p = 0.001], but time to antifungal initiation [2 days (0-14) vs. 2 (0-13), p = 0.369] and CVC removal within 48 h [90/185 (48.6%) vs. 148/319 (46.4%), p = 0.644] remained unchanged. Additionally, many patients went untreated in both periods I and II [87 (23.6%) vs. 43 (17.4%), p = 0.07], respectively. Unfortunately, no improvements in mortality rates at 14 days [123 (33.6%) vs. 93 (37.7%), p = 0.343] or at 30 days [188 (51.4%) vs. 120 (48.6%), p = 0.511] were observed. In conclusion, mortality rates remain exceedingly high despite therapeutic advances, probably associated with an increase in patients' complexity and suboptimal therapeutic interventions. Management strategies should be tailored to suit epidemiological changes, expedite diagnosis to reduce the number of untreated eligible patients and guarantee early antifungal initiation and source control.
