Fiberoptic bronchoscopy in the diagnosis and therapeutic decision for respiratory infections in hematological febrile neutropenic patients

INTRODUÇÃO: A neutropenia febril é uma complicação frequente dos pacientes submetidos ao tratamento quimioterápico ou Transplante de Célula Tronco Hematopioetica (TCTH). A fibrobroncoscopia(FBC) flexível tem sido utilizada para auxiliar no diagnóstico de doenças pulmonares. No entanto, não há consenso em relação ao benefício do exame para estabelecer diagnóstico e alterar o tratamento das doenças pulmonares nesse contexto. Estudos prévios, retrospectivos e bastante heterogêneos, com pacientes imunocomprometidos não-HIV mostraram que o rendimento da fibrobroncoscopia para estabelecer diagnóstico etiológico varia de 13 a 81% e gera alteração de terapêutica em 5 e 51%. O objetivo deste estudo foi avaliar o rendimento da Fibrobroncoscopia, o risco ao procedimento em pacientes hematológicos e neutropenicos. MÉTODOS: Estudo transversal retrospectivo que avaliou pacientes com neoplasia hematológica e neutropenia febril e que tenham sido submetidos à fibrobroncoscopia diagnóstica entre janeiro de 2011 e dezembro de 2012 internados no Hospital de Clínicas de Porto Alegre. RESULTADOS: Foram incluídos 45 pacientes: 18 (36%) tiveram resultado positivo no Lavado Broncoalveolar (LAB), sendo que houve mudança na conduta terapêutica em 95% dos pacientes que apresentaram positividade no LAB. Com relação ao risco do procedimento tivemos uma taxa de 2,2% de complicação, com um paciente que apresentou dessaturação imediatamente após o procedimento. CONCLUSÃO: Apesar do numero limitado de pacientes, nossos achados indicam que a realização da fibrobroncoscopia com LAB em pacientes neutropenicos é segura e com um rendimento semelhante aos descritos na literatura.INTRODUCTION: Febrile neutropenia is a common complication in patients undergoing chemotherapy or hematopoietic Stem Cell Transplantation (HSCT). Flexible fiberoptic bronchoscopy has been used to aid in the diagnosis of pulmonary diseases. However, there is no consensus regarding the benefit of the exam in establishing diagnosis and in changing the treatment of lung disease in this context. Previous retrospective studies, quite heterogeneous and with non-HIV immunocompromised patients, showed that the yield of fiberoptic bronchoscopy in establishing etiology ranges from 13% to 81%, and in changing therapy, from 5% to 51%. To evaluate the efficiency of Fiberoptic bronchoscopy and the procedurerelated risk for neutropenic patients with hematologic malignancy. METHODS: This retrospective cross-sectional study analyzed the medical records of patients with hematologic malignancy with febrile neutropenia who had undergone diagnostic fiberoptic bronchoscopy between January 2011 and December 2012 at the Hospital de Clínicas de Porto Alegre. RESULTS: A total of 45 patients were included: 18 (36%) tested positive for bronchoalveolar lavage, with change in therapeutic management occurring for 95% of them. The procedure-related risk was 2.2%, with one patient showing desaturation immediately after the procedure. CONCLUSION: Despite the limited number of patients, our findings indicate that fiberoptic bronchoscopy in neutropenic patients is safe, and the results are similar to those previously reported

Management of anticoagulation with vitamin K antagonists in a tertiary hospital outpatient clinic

Introduction: atrial fibrillation (AF) is one of the main risk factors for stroke. Vitamin K antagonists (VKA) reduce this risk, and the effectiveness of this treatment is directly related to time in therapeutic range (TTR). This study aimed to report the TTR in patients with non-valvular AF at an anticoagulation outpatient clinic; and to describe the profile of this population of patients in terms of risk of stroke, as well as the occurrence of adverse events during the follow-up. Methods: Retrospective cohort study involving patients of the anticoagulation outpatient clinic of the Department of Internal Medicine at Hospital de Clínicas de Porto Alegre. We evaluated outpatient visits, hospital admissions, and emergency visits from January to December 2011. TTR was calculated using the Rosendaal method. Results: Sixty-three patients were investigated. Their mean age was 74.3±10.9 years. The CHADS2 score was ≥ 4 in 44.5% of the patients; 63.5% of them had a CHA2DS2-VASc score ≥ 5. The TTR was 64.8%. During follow-up, the incidence of overall bleeding was 31.7%, with major and minor bleeding rates of 4.8% and 34.9%, respectively. There were no other complications related to AF or anticoagulation. Conclusion: The patients achieved a TTR of 64.8% during follow-up, which is deemed appropriate and in agreement with the literature. Patients had high risk for stroke, and the incidence of minor bleeding was higher than the rate found in the literature, whereas the incidence of major bleeding was similar to the one found in previous studies
