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.

COVID-19 IN INFLAMMATORY BOWEL DISEASE: SHOULD WE BE MORE CAREFUL WITH THE USE OF SALICYLATES?

BACKGROUNDS: Fortunately, much has been studied about COVID-19 in patients with inflammatory bowel diseases (IBD). Evidence suggests that these patients do not appear to be at increased risk of severe COVID-19. However, there are still some uncertainties regarding the clinical manifestations of COVID-19 in patients with immune-mediated diseases. OBJECTIVE: This study aimed to describe the main symptoms of COVID-19 and their frequency in IBD patients and evaluate the impact of the IBD therapeutic drugs on clinical presentation of COVID-19 and to determine factors associated with COVID-19 in this population. METHODS: Adult patients with IBD from three tertiary-care public, teaching hospitals in Ceará, Northeastern Brazil, were evaluated during one scheduled appointment from March to December 2020. Patients with possible or confirmed COVID-19 were compared with patients without COVID-19. Furthermore, incidences of each symptom were evaluated based on the use of IBD therapeutic drugs. RESULTS: A total of 515 patients with IBD were included in the study: 234 with CD, and 281 with UC. Of these, 174 patients (34%) had possible/confirmed COVID-19 of whom 156 (90%) were symptomatic. Main symptoms were fever (65%) and headache (65%); gastrointestinal symptoms occurred in one third of patients and were higher than COVID-19 in general population. The factors associated with having COVID-19 were female gender (OR 1.71, 95%CI: 1.17-2.50); contact at home (OR 5.07, 95%CI: 3.31-7.78) and outside the home (OR 3.14, 95%CI: 2.10-4.71) with a case of COVID-19; work outside of the home (OR 1.87, 95%CI: 1.26-2.78); family history of COVID-19 (OR 2.29, 95%CI 1.58-3.33) use of salicylate (OR 1.71, 95%CI: 1.17-4.28); and asthma (OR 7.10, 95%CI: 1.46-34.57). CONCLUSION: IBD patients at high risk of COVID-19 infection may need to avoid salicylate therapy but further studies are necessary to confirm this association.

Data-driven, cross-disciplinary collaboration: lessons learned at the largest academic health center in Latin America during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency. Methods: At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output. Results: Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19. Discussion: Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.

RESUMO Contexto: Felizmente, muito se tem estudado sobre a COVID-19 em pacientes com doenças inflamatórias intestinais (DII). As evidências sugerem que esses pacientes não parecem ter risco aumentado de COVID-19 grave. Mas ainda se tem algumas incertezas com relação às manifestações clínicas da COVID-19 em portadores de doenças imunomediadas. Objetivo: Este estudo teve como objetivo descrever os principais sintomas da COVID-19 e sua frequência em pacientes com DII e avaliar o impacto dos medicamentos utilizados no tratamento das DII na apresentação clínica da COVID-19. Métodos: Pacientes adultos com DII de três hospitais públicos terciários de ensino do Ceará, Nordeste do Brasil, foram avaliados em consulta ambulatorial no período de março a dezembro de 2020. Pacientes com COVID-19 possível ou confirmada foram comparados com pacientes sem COVID-19. Além disso, as incidências de cada sintoma foram avaliadas com base no uso de medicamentos utilizados para tratamento da DII. Resultados: Foram incluídos no estudo 515 pacientes com DII: 234 com DC e 281 com RCU. Destes, 174 pacientes (34%) tinham COVID-19 possível/confirmado, dos quais 156 (90%) eram sintomáticos. Os principais sintomas foram febre (65%) e dor de cabeça (65%); sintomas gastrointestinais ocorreram em um terço dos pacientes, sendo mais frequentes do que na população geral com COVID-19. Os fatores associados a ter COVID-19 foram sexo feminino (OR 1,71, IC95%: 1,17-2,50); ter contato com caso de COVID-19, tanto intradomiciliar (OR 5,07; IC95%: 3,31-7,78) como fora do domicílio (OR 3,14; IC95%: 2,10-4,71); trabalhar fora de casa (OR 1,87; IC95%: 1,26-2,78); história familiar de COVID-19 (OR 2,29, IC95% 1,58-3,33), uso de salicilato (OR 1,71, IC95%: 1,17-4,28) e asma (OR 7,10; IC95%: 1,46-34,57). Conclusão: Pacientes com DII com alto risco de infecção por COVID-19 podem precisar evitar a terapia com salicilatos, mas mais estudos são necessários para confirmar esta associação.

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

ABSTRACT 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.

Evaluation of eleven immunochromatographic assays for SARS-CoV-2 detection: investigating the dengue cross-reaction

ABSTRACT COVID-19 disease is spread worldwide and diagnostic techniques have been studied in order to contain the pandemic. Immunochromatographic (IC) assays are feasible and a low-cost alternative especially in low and middle-income countries, which lack structure to perform certain diagnostic techniques. Here we evaluate the sensitivity and specificity of eleven different IC tests in 145 serum samples from confirmed cases of COVID-19 using RT-PCR and 100 negative serum samples from blood donors collected in February 2019. We also evaluated the cross-reactivity with dengue using 20 serum samples from patients with confirmed diagnosis for dengue collected in early 2019 through four different tests. We found high sensitivity (92%), specificity (100%) and an almost perfect agreement (Kappa 0.92) of IC assay, especially when we evaluated IgG and IgM combined after 10 days from the onset of symptoms with RT-PCR. However, we detected cross-reactivity between dengue and COVID-19 mainly with IgM antibodies (5 to 20% of cross-reaction) and demonstrated the need for better studies about diagnostic techniques for these diseases.

Use and misuse of biomarkers and the role of D-dimer and C-reactive protein in the management of COVID-19: A post-hoc analysis of a prospective cohort study

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

Characterization of epidemiological surveillance systems for healthcare-associated infections (HAI) in the world and challenges for Brazil / Caracterizacao dos sistemas de vigilancia epidemiologica das infeccoes relacionadas a assistencia a saude (IRAS) no mundo e desafios para o Brasil / Caracterizacion de los sistemas de vigilancia epidemiologica de las infecciones asociadas a la atencion en salud (IAAS) en el mundo y los desafios para Brasil

Surveillance systems for healthcare-associated infections (HAI) are essential for planning actions in prevention and control. Important models have been deployed in recent decades in different countries. This study aims to present the historical and operational characteristics of these systems and discuss the challenges for Brazil. Various models around the world have drawn on the experience of the United States, which pioneered this process. In Brazil, several initiatives have been launched, but the country still lacks a full national information system on HAI, thus indicating the need to promote action strategies, strengthen the role of States in communication between the Federal and local levels, pursue a national plan to organize surveillance teams with the necessary technological infrastructure, besides updating the relevant legislation for dealing with these challenges. Such measures are essential in the Brazilian context for the unified surveillance of HAI, aimed at healthcare safety and quality.

A formação de sistemas de vigilância de infecções relacionadas à assistência à saúde (IRAS) é medida essencial para o planejamento de ações de prevenção e controle. No mundo, importantes modelos estão sendo implantados nas últimas décadas. Este estudo busca apresentar os aspectos históricos e operacionais desses sistemas, discutindo os desafios para o Brasil. Os modelos internacionais se espelham no exemplo americano, pioneiro nesse processo. No Brasil, diversas iniciativas foram e estão sendo estabelecidas, entretanto, não temos um pleno sistema nacional de informação sobre IRAS, o que aponta a necessidade de reconhecer estratégias em vigência, fortalecendo o Estado como elo de comunicação; buscando um plano nacional para a formação de equipes de vigilância com aparato tecnológico necessário, e discutindo a atualização das legislações que já não contemplam os desafios atuais de tais ocorrências. Essas são medidas essenciais no contexto brasileiro para a vigilância unificada de IRAS, almejando segurança e qualidade nos cuidados em saúde.

La formación de los sistemas de vigilancia de infecciones asociadas a la atención en salud (IAAS) es una medida esencial para la planificación de acciones de prevención y control. Algunos modelos importantes en el mundo se están desplegando en las últimas décadas. Este estudio analiza los aspectos históricos y operativos de estos sistemas, discutiendo los desafíos para Brasil. Los modelos internacionales se reflejan en el ejemplo norteamericano, pionero en este proceso. En Brasil varias iniciativas han sido y están siendo establecidas, sin embargo, no se dispone de un pleno sistema nacional de información sobre IAAS, señalando la necesidad de reconocer estrategias vigentes; así como el fortalecimiento del Estado como un enlace de comunicación, buscando un plan nacional para formar equipos de vigilancia con los aparatos tecnológicos necesarios, así como discutiendo la actualización de las leyes que ya no incluyen los desafíos actuales para este tipo de ocurrencias. Estos son pasos esenciales en el contexto brasileño para el control unificado de las IAAS con los objetivos de seguridad y calidad en el cuidado de la salud.

The minimal inhibitory concentration for sulbactam was not associated with the outcome of infections caused by carbapenem-resistant Acinetobacter sp. treated with ampicillin/sulbactam

OBJECTIVE: The objective of this study was to evaluate whether the outcomes of carbapenem-resistant Acinetobacter infections treated with ampicillin/sulbactam were associated with the in vitro susceptibility profiles. METHODS: Twenty-two infections were treated with ampicillin/sulbactam. The median treatment duration was 14 days (range: 3-19 days), and the median daily dose was 9 g (range: 1.5-12 g). The median time between Acinetobacter isolation and treatment was 4 days (range: 0-11 days). RESULTS: The sulbactam minimal inhibitory concentration (MIC) ranged from 2.0 to 32.0 mg/L, and the MIC was not associated with patient outcome, as 4 of 5 (80%) patients with a resistant infection (MIC≥16), 5 of 10 (50%) patients with intermediate isolates (MIC of 8) and only 1 of 7 (14%) patients with susceptible isolates (MIC ≤4) survived hospitalization. CONCLUSION: These findings highlight the need to improve the correlation between in vitro susceptibility tests and clinical outcome. .

Smqnr VARIANTS IN CLINICAL ISOLATES OF Stenotrophomonas maltophilia IN BRAZIL / Variantes de Smqnr de isolados clínicos de Stenotrophomonas maltophilia no Brasil

SUMMARY Stenotrophomonas maltophilia contains a novel chromosomally-encoded qnr gene named Smqnr that contributes to low intrinsic resistance to quinolone. We described Smqnr in 13 clinical isolates of S. maltophilia from two Brazilian hospitals, over a 2-year period. The strains were identified by API 20 NE (bioMérieux, France). Susceptibility by microdilution method to trimetroprim/sulfamethoxazole, ciprofloxacin, levofloxacin, minocycline, ceftazidime, chloramphenicol and ticarcillin/clavulanate was performed according to CLSI. PCR detection of Smqnr gene was carried out. The sequence of Smqnr was compared with those deposited in GenBank. Pulsed-field gel electrophoresis (PFGE) of all strains was performed. Thirteen Smqnr positives isolates were sequenced and three novel variants of Smqnr were identified. All 13 Smqnr isolates had distinguishable patterns by PFGE. This is the first report of Smqnr in S. maltophilia isolated in Brazil. .

RESUMO S. maltophilia contem um novo gene qnr cromossômico denominado Smqnr que contribui para baixa resistência intrínseca a quinolonas. Descrevemos Smqnr em 13 isolados clínicos de S. maltophilia de dois hospitais brasileiros, ao longo do período de dois anos. Os isolados foram identificados pela API 20 NE (bioMérieux, França). Susceptibilidade pelo método de microdiluição dos seguintes antibióticos trimetroprim/sulfametoxazol, ciprofloxacina, levofloxacina, minociclina, ceftazidima, cloranfenicol e ticarcilina/clavulanato foi realizada segundo o CLSI. Detecção do gene de Smqnr foi realizada por PCR. A sequência de Smqnr foi comparada com aquelas depositadas no GenBank. Foi realizada eletroforese em gel de campo pulsado (PFGE) de todos os isolados. Treze isolados contendo Smqnr foram sequenciados e identificados três variantes do gene Smqnr. Todos os 13 isolados de Smqnr apresentaram diferentes padrões por PFGE. Este é o primeiro relato de Smqnr em isolados de S. maltophilia no Brasil. .

Colonization pressure as a risk factor for colonization by multiresistant Acinetobacter spp and carbapenem-resistant Pseudomonas aeruginosa in an intensive care unit

OBJECTIVE: To determine factors associated with colonization by carbapenem-resistant Pseudomonas aeruginosa and multiresistant Acinetobacter spp. METHODS: Surveillance cultures were collected from patients admitted to the intensive care unit at admission, on the third day after admission and weekly until discharge. The outcome was colonization by these pathogens. Two interventions were implemented: education and the introduction of alcohol rubs. Compliance with hand hygiene, colonization pressure, colonization at admission and risk factors for colonization were evaluated. RESULTS: The probability of becoming colonized increased during the study. The incidence density of colonization by carbapenem-resistant P. aeruginosa and multiresistant Acinetobacter spp. and colonization pressure were different between periods, increasing gradually throughout the study. The increase in colonization pressure was due to patients already colonized at admission. The APACHE II score, colonization pressure in the week before the outcome and male gender were independent risk factors for colonization. Every 1% increase in colonization pressure led to a 2% increase in the risk of being colonized. CONCLUSION: Colonization pressure is a risk factor for carbapenem-resistant P. aeruginosa and multiresistant Acinetobacter spp. colonization. When this pressure reaches critical levels, efforts primarily aimed at hand hygiene may not be sufficient to prevent transmission. .

Guidelines on management of human infection with the novel virus influenza A (H1N1): a report from the Hospital das Clínicas of the University of São Paulo

The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July, 2009. Since then, 9.249 cases were confirmed in Brazil, most of them concentrated in São Paulo. The Hospital das Clínicas of the University of São Paulo is a reference center for H1N1 cases in São Paulo. The purpose of this review is to analyze the evidence concerning diagnosis, prevention, and treatment of novel influenza A (H1N1) infection. In addition, we propose guidelines for the management of this pandemic emphasizing Hospital das Clínicas "bundles" for the control of the pandemic novel influenza A (H1N1).

Epidemiology of human infection with the novel virus influenza A (H1H1) in the Hospital das Clínicas, São Paulo, Brazil - june-september 2009

The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July 16, 2009. Since then, 46,810 cases of acute respiratory syndrome have been reported in Brazil, most of them concentrated in São Paulo. Through September 16, we have confirmed 9,249 cases of novel influenza A H1N1in Brazil, including 699 deaths. The mortality rate observed in Brazil is 0.47/100,000 inhabitants and varies according to region. In this period, São Paulo registered 3733 cases (40.3 percent of the total) of novel influenza A (H1N1) infection and 327 deaths, reflecting a mortality rate of 0.79/100,000 inhabitants. The Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC) is a reference center for H1N1 cases in São Paulo. During the winter of 2009, 472 patients in this hospital were diagnosed with H1N1 infection; of these, 210 were admitted, and 16 died. To control this pandemic and to provide adequate care for these patients, the Hospital das Clínicas implemented "bundles" including prevention strategies, an epidemiologic surveillance service, availability of fast diagnosis, antiviral treatment and training of staff. The purpose of this manuscript is to describe the epidemiologic features of novel human influenza A (H1N1) infection in the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the winter period of the 2009 pandemic.

Fulminant hepatitis: a clinical review of 11 years

Vinte e quatro casos de hepatite fulminante (HF), internados na Clínica de Doenças Infecciosas e Parasitárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de Säo Paulo durante o período de janeiro de 1976 a dezembro de 1986, foram revistos para a obtençäo de dados clínicos, epidemiológicos e laboratoriais. 88% dos pacientes morreram. Vinte (83%) dos pacientes apresentaram hemorragias, dentre os quais 19 morreram (95%). Infecçöes bacterianas secundárias ocorreram em 14 pacientes (58%) todos os quais faleceram. Ascite foi notada em 3 casos e edema cerebral em 16 casos. Os valores máximos de ALT obtidos para cada paciente durante a internaçäo variaram de 81 a 40460 UI/l. Treze pacientes tiveram elevaçäo de creatinina (54%). A atividade do tempo de protrombina variou de 2,1% a 67%. A febre esteve presente em 20 casos (83%). A encefalopatia surgiu durante as 2 primeiras semanas de doenças em 72% dos casos. Em 7 casos havia doenças associadas à hepatite. A etiologia näo pode ser determinada em 13 casos; 3 casos foram por febre amarela; e 6 casos por outros vírus. Em 1 caso a causa foi drogas e em um caso, possivelmente, foi álcool. Os autores acreditam que a definiçäo de HF merece discussäo antes de ser totalmente aceita. Neste estudo, a HF foi uma doença que acometeu principalmente jovens. A letadade encontrada foi semelhante a de outros estudos. Fatores que contribuiram para o óbito foram hemorragias e infecçöes bacterianas secundárias. Fatores de piora do prognóstico de hepatite foram a presença de outras doenças associadas e de procedimento cirurgico. Os níveis de ALT durante a internaçäo näo refletiram a gravidade da hepatite. Os autores acreditam que a febre amarela deve ser considerada um agente etiológico de HF quando o seu quadro clínico seja compatível com tal, embora os mecanismos fisiopatológicos da encefalopatia sejam ainda obscuros. Os dados clínicos dos 3 casos de febre amarela säo apresentados à parte

Resistance of streptococcus pneumoniae to antimicrobials in São Paulo, Brazil: clinical features and serotypes

To study resistance to antimicrobials, serotypes and clinical features of S. pneumoniae in S. Paulo, Brazil, 50 patients with a positive culture were evaluated: 7 were considered carriers and 43 had pneumococcal infections. Pneumonia and meningitis were the most common infections. Mortality was 34 and underlying diseases were present in 70. Relative resistance to penicillin occurred in 24 and complete resistance was not detected. Resistance to tetracycline was 32 and to sulfamethoxazole/trimethoprim 32; one strain had intermediate susceptibility to erythromycin; no resistance was present for chloramphenicol, rifampin or vancomycin. Resistance to at least one of the drugs tested occurred in 62. Results by the E-test for penicillin were similar to those by the agar dilution method. There were 24 different serotypes and 74 of the strains belonged to the 23-valent vaccine including all the penicillin-resistant strains. In this study S. pneumoniae caused severe infections and presented a high resistance rate to commonly used antimicrobials. Routine surveillance of resistance and the use of vaccination, as well as the restriction of inappropriate use of antimicrobials, are recommended in São Paulo, Brazil.

Five cases of nosocomial and community-acquired Legionnaires' disease in São Paulo, Brazil

Legionella sp has been emerging over the last decade as an important cause of pneumonia both hospital and community-acquired. Following an outbreak in a Renal-Transplant Unit stocked serum was tested for antibodies against Legionella pneumophila serogroup 1, and 5 cases of Legionnaires' Disease were reviewed. Two of the cases were nosocomial and three cases were community-acquired. Clinical and laboratorial aspects were similar to those expected for other causes of pneumonia, however jaundice was encountered in two cases. This study suggests that the real incidence of pneumonia caused by Legionella sp is being underestimated and the authors emphasize the importance of considering Legionnaires' Disease when empirically treating community-acquired pneumonia.

Legionnaires'disease in the renal transplant unit of Hospital das Clinicas FMUSP: during a five year period (1988-1993)

Embora varios trabalhos tem mostrado a presenca de Legionella pneumophila associado a pneumopatias infecciosas em transplantados renais, tal associacao nao fora antes realizado de maneira sistematica no Brasil. Os autores julgaram oportuno a determinacao da incidencia por comprovacao sorologica da Legionella pneumophila sorogrupo 1 em transplantados renais num periodo de 5 anos. Para tanto amostras de soros de 70 pacientes com pneumopatia infecciosa internados na UTR do HC-FMUSP, colhidos na fase aguda e convalescente da infeccao, foram submetidas a reacao de imunofluorescencia indireta para pesquisa de anticorpos anti-Legionella pneumophila sorogrupo 1....
