ABSTRACT Background Several therapies have been used or proposed for the treatment of COVID-19, although their effectiveness and safety have not been properly evaluated. The purpose of this document is to provide recommendations to support decisions about the drug treatment of outpatients with COVID-19 in Brazil. Methods A panel consisting of experts from different clinical fields, representatives of the Brazilian Ministry of Health, and methodologists (37 members in total) was responsible for preparing these guidelines. A rapid guideline development method was used, based on the adoption and/or adaptation of recommendations from existing international guidelines combined with additional structured searches for primary studies and new recommendations whenever necessary (GRADE-ADOLOPMENT). The rating of quality of evidence and the drafting of recommendations followed the GRADE method. Results Ten technologies were evaluated, and 10 recommendations were prepared. Recommendations were made against the use of anticoagulants, azithromycin, budesonide, colchicine, corticosteroids, hydroxychloroquine/chloroquine alone or combined with azithromycin, ivermectin, nitazoxanide, and convalescent plasma. It was not possible to make a recommendation regarding the use of monoclonal antibodies in outpatients, as their benefit is uncertain and their cost is high, with limitations of availability and implementation. Conclusion To date, few therapies have demonstrated effectiveness in the treatment of outpatients with COVID-19. Recommendations are restricted to what should not be used, in order to provide the best treatment according to the principles of evidence-based medicine and to promote resource savings by aboiding ineffective treatments.

Resumen: En | Texto: En | PDF: En

Abstract Chronic hepatitis B is an important health problem that can progress to cirrhosis and complications such as hepatocellular carcinoma. There is approximately 290 million of people with chronic hepatitis B virus (HBV) infection worldwide, however only 10% of patients are currently identified.Most part of Brazil is considered of low prevalence of HBV infection but there are some regions with higher frequency of carriers. Unfortunately, many infected patients are not yet identified nor evaluated for treatment.The Brazilian Society of Infectious Diseases (SBI) and the Brazilian Society of Hepatology worked together to elaborate a guideline for diagnosis and treatment of hepatitis B. The document includes information regarding the population to be tested, diagnostic tools, indications of treatment, therapeutic schemes and also how to handle HBV infection in specific situations (pregnancy, children, immunosuppression, etc).Delta infection is also part of the guideline, since it is an important infection in some parts of the country.

RESUMO Introdução: Há diversas terapias sendo utilizadas, consideradas ou propostas para o tratamento da COVID-19, muitas carecendo de apropriada avaliação de efetividade e segurança. O propósito deste documento é fornecer recomendações baseadas nas evidências científicas disponíveis e em sua interpretação transparente, para subsidiar decisões sobre o tratamento farmacológico da COVID-19 no Brasil. Métodos: Um grupo de 27 especialistas e metodologistas integraram a força-tarefa formada pela Associação de Medicina Intensiva Brasileira (AMIB), pela Sociedade Brasileira de Infectologia (SBI) e pela Sociedade Brasileira de Pneumologia e Tisiologia (SBPT). Foram realizadas revisões sistemáticas rápidas, atualizadas até 28 de abril de 2020. A qualidade das evidências e a elaboração das recomendações seguiram o sistema GRADE. As recomendações foram elaboradas nos dias 5, 8 e 13 de maio de 2020. Resultados: Foram geradas 11 recomendações, embasadas em evidência de nível baixo ou muito baixo. Não há indicação para uso de rotina de hidroxicloroquina, cloroquina, azitromicina, lopinavir/ritonavir, corticosteroides ou tocilizumabe no tratamento da COVID-19. Heparina deve ser utilizada em doses profiláticas no paciente hospitalizado, mas não deve ser realizada anticoagulação na ausência de indicação clínica específica. Antibacterianos e oseltamivir devem ser considerados somente nos pacientes em suspeita de coinfecção bacteriana ou por influenza, respectivamente. Conclusão: Até o momento, não há intervenções farmacológicas com efetividade e segurança comprovada que justifiquem seu uso de rotina no tratamento da COVID-19, devendo os pacientes serem tratados preferencialmente no contexto de pesquisa clínica. As recomendações serão revisadas continuamente, de forma a capturar a geração de novas evidências.

ABSTRACT Introduction: Different therapies are currently used, considered, or proposed for the treatment of COVID-19; for many of those therapies, no appropriate assessment of effectiveness and safety was performed. This document aims to provide scientifically available evidence-based information in a transparent interpretation, to subsidize decisions related to the pharmacological therapy of COVID-19 in Brazil. Methods: A group of 27 experts and methodologists integrated a task-force formed by professionals from the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB), the Brazilian Society of Infectious Diseases (Sociedad Brasileira de Infectologia - SBI) and the Brazilian Society of Pulmonology and Tisiology (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT). Rapid systematic reviews, updated on April 28, 2020, were conducted. The assessment of the quality of evidence and the development of recommendations followed the GRADE system. The recommendations were written on May 5, 8, and 13, 2020. Results: Eleven recommendations were issued based on low or very-low level evidence. We do not recommend the routine use of hydroxychloroquine, chloroquine, azithromycin, lopinavir/ritonavir, corticosteroids, or tocilizumab for the treatment of COVID-19. Prophylactic heparin should be used in hospitalized patients, however, no anticoagulation should be provided for patients without a specific clinical indication. Antibiotics and oseltamivir should only be considered for patients with suspected bacterial or influenza coinfection, respectively. Conclusion: So far no pharmacological intervention was proven effective and safe to warrant its use in the routine treatment of COVID-19 patients; therefore such patients should ideally be treated in the context of clinical trials. The recommendations herein provided will be revised continuously aiming to capture newly generated evidence.

Resumen: En | Texto: En | PDF: En

ABSTRACT Urinary tract infection (UTI) is a common condition in women. There is an increased concern on reduction of bacterial susceptibility resulting from wrongly prescribing antimicrobials. This paper summarizes the recommendations of four Brazilian medical societies (SBI - Brazilian Society of Infectious Diseases, FEBRASGO - Brazilian Federation of Gynecology and Obstetrics Associations, SBU - Brazilian Society of Urology, and SBPC/ML - Brazilian Society of Clinical Pathology/Laboratory Medicine) on the management of urinary tract infection in women.Asymptomatic bacteriuria should be screened at least twice during pregnancy (early and in the 3rd trimester). All cases of significant bacteriuria (≥105 CFU/mL in middle stream sample) should be treated with antimicrobials considering safety and susceptibility profile. In women with typical symptoms of cystitis, dipsticks are not necessary for diagnosis. Urine cultures should be collected in pregnant women, recurrent UTI, atypical cases, and if there is suspicion of pyelonephritis. First line antimicrobials for cystitis are fosfomycin trometamol in a single dose and nitrofurantoin, 100 mg every 6 hours for five days. Second line drugs are cefuroxime or amoxicillin-clavulanate for seven days. During pregnancy, amoxicillin and other cephalosporins may be used, but with a higher chance of therapeutic failure.In recurrent UTI, all episodes should be confirmed by urine culture. Treatment should be initiated only after urine sampling and with the same regimens indicated for isolated episodes. Prophylaxis options of recurrent UTI are behavioral measures, non-antimicrobial and antimicrobial prophylaxis. Vaginal estrogens may be recommended for postmenopausal women. Other non-antimicrobial prophylaxis, including cranberry and immunoprophylaxis, have weak evidence supporting their use. Antimicrobial prophylaxis may be offered as a continuous or postcoital scheme. In pregnant women, options are cephalexin, 250-500 mg and nitrofurantoin, 100 mg (contraindicated after 37 weeks of pregnancy). Nonpregnant women may use fosfomycin trometamol, 3 g every 10 days, or nitrofurantoin, 100 mg (continuous or postcoital).

Resumen: En | Texto: En | PDF: En

ABSTRACT The Choosing Wisely Initiative aims to collect statements from medical societies all over the world on medical interventions that result in no benefit to patients, with the potential to cause harm. In this article we present the views of the Diagnostic Laboratory Group at the Brazilian Society of Infectious Diseases (SBI). Ten experts from SBI were asked to list 10 diagnostic tests that were perceived as unnecessary in the field of infectious diseases. After voting for the more relevant topics, a questionnaire was sent to all SBI members, in order to select for the most important items. A total of 482 votes were obtained, and the top 10 results are shown in this manuscript. The Choosing Wisely statements of SBI should facilitate clinical practice by optimizing the use of diagnostic resources in the field of infectious diseases.

It has been suggested that the clinical features of giardiasis might vary in patients of different age groups. Objective: To compare clinical presentation of giardiasis in children less than 5 years of age and older children. Methods: A retrospective study of patients hospitalized with giardiasis during 2007 was performed. The clinical features of the two age groups were compared. Additionally, length of stay was analyzed. Results: In total, 170 patients were included. In children ≥ 5 years of age, abdominal pain and urticaria were significantly more frequent (OR=9.46; 95%CI: 4.35-20.52,P5=0.000+ and OR=11.0; 95%CI: 1.205-101.11, P=0.023, respectively). Diarrhoea was more frequently found in children younger than 5 years (OR=6.45; IC 95%: 3. 12-13.37, P=0.000+). The frequencies of other symptoms were similar. Length of stay was significantly higher in children under 5 years of age. Discussion and conclusions: Clinical presentations differed in some aspects among the examined age group of our paediatric patients. Our finding might be of importance for an early recognition of giardiasis, which is essential for an accurate diagnosis and a prompt treatment.

La giardiosis es una enfermedad frecuente a escala internacional. Se ha sugerido por algunos autores que su presentación clínica puede variar con la edad. Objetivo: Comparar las manifestaciones clínicas de la giardiosis en los niños hospitalizados bajo 5 años de edad con las de niños de 5 años o más. Métodos: Estudio retrospectivo realizado en el Hospital Pediátrico de Centro Habana durante el año 2007. Las manifestaciones clínicas fueron extraídas utilizando un formulario prediseñado y separadas de acuerdo a los grupos de edades estudiados. Adicionalmente, se extrajo la estadía hospitalaria. Resultados: Se incluyeron 170 pacientes. Los niños de 5 y más años de edad manifestaron con mayor frecuencia dolor abdominal (OR = 9,46; IC 95%: 4,35-20,52, p = 0,000+) y urticaria (OR = 11,0; IC 95%: 1,205-101,11, p = 0,023), mientras que la diarrea se encontró más frecuentemente bajo 5 años de edad (OR = 6,45; IC 95%: 3,12-13,37, p = 0,000+). En el resto de las manifestaciones clínicas no se encontraron diferencias significativas en sus frecuencias entre ambos grupos de edades (p > 0,05). La estadía hospitalaria fue significativamente más prolongada entre los pacientes bajo 5 años de edad. Discusión y conclusiones: Las manifestaciones clínicas pueden variar en algunos aspectos entre los diferentes grupos de edades pediátricas. Su rápido reconocimiento es esencial con el fin de arribar a un diagnóstico preciso y al tratamiento oportuno.

INTRODUÇÃO: Estudos indicam a Dientamoeba fragilis como uma das causas de diarréia em pacientes com HIV/AIDS. MÉTODOS: Os objetivos deste estudo foram avaliar a prevalência de D. fragilis associadas com as causas de diarréia em pacientes com HIV/AIDS internados no Instituto de Infectologia Emílio Ribas (IIER). Oitenta e dois pacientes internados no IIER fizeram parte deste estudo de setembro de 2006 a novembro de 2008. RESULTADOS: No total, 105 amostras foram coletadas a partir de 82 pacientes neste estudo. Sexo desprotegido foi à causa mais frequente para a aquisição do HIV (46,3%), seguido pelo uso de drogas injetáveis ou não injetáveis (14,6%). Relações heterossexuais foram os mais citados (19,5%). Pacientes apresentaram carga viral entre 49 e 750.000 (média de 7.849 ± 124.850) e CD4 variando de 2 a 1.306 (média de 159 ± 250). Em média, as chances de um resultado ser positivo com outras técnicas foram 2,7 vezes maiores do que a chance de um resultado positivo com hematoxilina férrica simplificada. Foram encontradas diferenças significativas entre os métodos (p=0,003). CONCLUSÕES: As outras técnicas são capazes de detectar uma quantidade significativa maior de parasitas em comparação com a hematoxilina férrica simplificada, especialmente em relação à Isospora belli, Cryptosporidium sp., Schistossoma mansoni e Strongyloides stercoralis que não foram encontrados utilizando a hematoxilina e a Endolimax nana e D. fragilis foram mais detectados pela hematoxilina férrica simplificada, principalmente a D. fragilis que não foi detectada pelos outros métodos.

INTRODUCTION: Studies strongly indicate Dientamoeba fragilis as one of the causes of diarrhea in human immunodeficiency virus (HIV) patients. METHODS: The objective of the present study was to evaluate the prevalence of D. fragilis associated with the causes of diarrhea in 82 HIV/ AIDS patients hospitalized at the Instituto de Infectologia Emílio Ribas from September 2006 to November 2008. RESULTS: In total, 105 samples were collected from 82 patients. Unprotected sex was the most frequent cause of HIV infection (46.3%), followed by the use of injectable or non-injectable drugs (14.6%). Patients presented with viral loads of 49-750,000 copies/ mL (average: 73,849 ± 124,850 copies/mL) and CD4 counts ranging of 2-1,306 cells/mm³ (average: 159 ± 250 cells/mm³). On an average, the odds of obtaining a positive result by using the other techniques (Hoffman, Pons and Janer or Lutz; Ritchie) were 2.7 times higher than the chance of obtaining a positive result by using the simplified iron hematoxylin method. Significant differences were found between the methods (p = 0.003). CONCLUSIONS: The other techniques can detect a significantly greater amount of parasites than the simplified iron hematoxylin method, especially with respect to Isospora belli, Cryptosporidium sp., Schistosoma mansoni, and Strongyloides stercoralis, which were not detected using hematoxylin. Endolimax nana and D. fragilis were detected more frequently on using hematoxylin, and the only parasite not found by the other methods was D. fragilis.

Resumen: En | Texto: En | PDF: En

In the advanced stages of AIDS, characterized by severe immunodepression, tuberculosis (TB) may present with a clinical picture of septic shock, due to typical bacteremia. Hematogenic dissemination of mycobacteria is frequent in immunodepressed patients with TB or disseminated mycobacteriosis, leading to increased positivity in detection by automated blood culture. The objective of our study was to determine the prevalence of mycobacteremia in patients with AIDS and with prolonged fever seen at the Emilio Ribas Institute of Infectology. Patients with a history of daily fever (37.8ºC), lasting more than 30 days, and with CD4+ helper lymphocyte counts below 200 cells/mL, were selected from February 2001 to March 2002. A 5 mL peripheral blood sample was collected from each patient for mycobacterial blood culture by an automated method, using the BACTEC 9000 MB and MB/BACT techniques. Forty-five patients aged on average 35 years, most of them males, were included in the study. The mean T CD4+ lymphocyte count was 58 cells/mL. Among the samples submitted to blood culture, 30% gave M. tuberculosis growth, with 62% sensitivity. Among the patients with a negative blood culture, nine had received a diagnosis of TB by another method. Automated blood culture proved to be a technique of relevant diagnostic value for M. tuberculosis in patients with prolonged fever in advanced stages of AIDS. The method is simple, and it helps the physician to select the best therapeutic option.
