ABSTRACT

Infecções por micobactéria não tuberculosa (MNT) representam uma emergência epidemiológica e sanitária, especialmente, em pacientes submetidos a procedimentos invasivos. Frente ao exposto, objetivou-se analisar as evidências científicas, na literatura científica, sobre a ocorrência no Brasil de infecções por MNT em pacientes cirúrgicos. Utilizou-se como método de pesquisa a revisão integrativa da literatura nas bases de dados Lilacs, Medline/Pubmed, ISI Web of Science e Biblioteca Cochrane. Foram selecionadas 15 publicações sobre a temática nos últimos 30 anos que estavam direcionadas às medidas de prevenção e controle com foco na vigilância pós-alta, no uso de antibioticoterapia e glutaraldeído. Cirurgias oftalmológicas, estéticas, cardíacas e procedimentos laparoscópicos e artroscópicos foram as mais investigadas. A situação nacional das MNTs é preocupante, ainda mais quando se reconhece a possibilidade de subnotificação.


Infections caused by nontuberculous mycobacteria (MNT) represent an epidemiological and health emergency, especially in patients undergoing invasive procedures. Based on these, we aimed to analyze the scientific evidence, the scientific literature, on the occurrence in Brazil of MNT infections in surgical patients. We used as a research method integrative review of the literature using the databases Lilacs, Medline/Pubmed, ISI Web of Science and the Cochrane Library. We selected 15 publications on this theme from the last 30 years that were directed at methods of prevention and control, with a focus on post-discharge surveillance, the use of antibiotics and glutaraldehyde. Eye surgery, cosmetic, heart, laparoscopic and arthroscopic procedures were the most commonly investigated. The national situation of MNTs is concerning, especially when one recognizes the possibility of underreporting.

ABSTRACT

A úlcera de Buruli, uma doença infecciosa causada pela Mycobacterium ulcerans (M. ulcerans),é a terceira micobacteriose em ocorrência, após a hanseníase e a tuberculose. Essa micobacteriose atípica tem sido relatada em mais de 30 países, principalmente, nos que têm climas tropicais e subtropicais, mas a sua epidemiologia permanece obscura. Recentemente, os primeiros casos autóctones do Brasil foram relatados, fazendo com que dermatologistas brasileiros estejam atentos a esse diagnóstico. O quadro clínico varia: nódulos, áreas de edema, placas, mas a manifestação mais típica é uma grande úlcera, que ocorre, em geral, nas pernas ou nos braços. Apesar do amplo conhecimento quanto ao seu quadro clínico em países endêmicos, nas outras áreas, esse diagnóstico pode passar despercebido. Assim, médicos devem ser orientados quanto à úlcera de Buruli, pois o diagnóstico precoce, o tratamento específico e a introdução de cuidados na prevenção de incapacidades são essenciais para uma boa evolução.


Buruli ulcer, an infectious disease caused by Mycobacterium ulcerans, is the third most prevalent mycobacteriosis, after tuberculosis and leprosy. This atypical mycobacteriosis has been reported in over 30 countries, mainly those with tropical and subtropical climates, but its epidemiology remains unclear. The first autochthonous cases of infection in Brazil have recently been described, making this diagnosis important for Brazilian dermatologists. Clinical manifestations vary from nodules, areas of edema, and plaques, but the most typical presentation is a large ulcer, usually in the limbs. Despite considerable knowledge about its clinical manifestations in some endemic countries, in other areas the diagnosis may be overlooked. Therefore, physicians should be educated about Buruli ulcer, since early diagnosis and treatment, including measures to prevent disability, are essential for a good outcome.

ABSTRACT

We report a case of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule (SPN). A 35-year-old male was admitted due to a SPN in the right upper lobe which was detected on the chest radiography being examed due to recurrent cough for 1 year. The computed tomography (CT) revealed a spiculated nodule containing air-bronchogram, which was suspicious of malignancy. We performed transbronchial biopsy and the pathology showed granulomatous inflammation with caseous necrosis. Under the presumptive diagnosis of pulmonary tuberculosis, we started anti-tuberculous medication including isoniazid, rifampin, ethambutol, and pyrazinamide. In one month, however, the sputum culture was positive for Mycobacterium intracellulare. The follow-up chest CT showed slight aggravation of the previous lesions. Under the final diagnosis of Mycobacterium intracellulare pulmonary infection presenting as a solitary pulmonary nodule, we changed the regimen to rifampin, ethambutol, and clarithromycin. The follow-up chest CT after the completion of treatment, revealed resolution of the previous lesions.

ABSTRACT

Between August 2006 and February 2007, in the state of Rio de Janeiro, Brazil, a massive outbreak of RGM infections after video laparoscopy was mainly associated to the recently described Mycobacterium massiliense species. All confirmed and probable cases reports described the use of high-level disinfection of medical devices by using 2 percent glutaraldehyde (2 percent GA) for 30 min before the surgical procedures. We investigated the susceptibility of the M. massiliense isolates recovered during the outbreak to high-level disinfection after 30 min, 1h, 6h and 10h of exposure to the commercial disinfectants. Reference strains for official mycobactericidal tests such as Mycobacterium abscessus, Mycobacterium bovis, Mycobacterium chelonae, Mycobacterium neoaurum and Mycobacterium smegmatis were included as controls. Although all the reference strains were eliminated in 30 min of exposure to 2 percent GA, we observed the recovery of all M. massiliense clinical isolates even after 10h of exposure. This study suggests that failures in high-level disinfection and the high tolerance of these M. massiliense clinical strains to the 2 percent GA were strongly associated to the magnitude of the outbreak.

ABSTRACT

Mycobacterium kansasii is one of the most common cause of pulmonary diseases due to nontuberculous mycobacteria. We investigated the changing in the number of isolation of M. kansasii and the clinical characteristics of M. kansasii pulmonary disease in Korea. Through searching the database of the Korean Institute of Tuberculosis, we identified the cases of isolated M. kansasii from 1992 to 2002. The number of M. kansasii isolation had increased from once in 1992 to 62 in 2002. Fifteen patients with M. kansasii pulmonary disease were identified during the period January 1997 to December 2002. Twelve patients (80%) were male and fourteen (93%) were from highly industrialized areas. The most common symptom was a cough. Seven patients (47%) had a cavitary lesion and right upper lobe was most commonly involved. Patients responded well to isoniazid and rifampicin based regimens both bacteriologically and radiographically. In conclusion, M. kansasii isolation has increased, especially in highly industrialized areas, as well as other nontuberculous mycobacteria in Korea.

ABSTRACT

The purpose of this study was to explore the incidence of tuberculosis (TB) in chronic renal failure (CRF) patients with or without renal replacement therapy and to evaluate the effect of chemoprophylaxis on incidence of active TB. A total of 3360 CRF patients from April 1989 to Sept. 2002 were enrolled in this study. Chemoprophylaxis for TB was given to the patients with increased serum anti PPD IgG levels from Jan. 1995 to Sept. 2002. The prevalence of active TB during this period was compared with that of the historical control group from April 1989 to Dec. 1998 (without prophylaxis). The results showed that the overall incidence of active TB in all patients was 2 4% (82/3360). Extrapulmonary TB was the most common feature (75 6%) with the major infective sites in pleura (20 7%) and lymph node (17 7%). There were 58 5% patients with active TB showing increased serum and/or serous exudate anti PPD IgG levels and 24 2% patients showing positive TB bacillus DNA (PCR). The total incidences of TB (1 76%) and disseminated TB (2 3%) in the chemoprophylaxis group were significantly lower than those in the non chemoprophylaxis group (4 1% and 7 5%, respectively, P
