Clinical and laboratory characteristics of 71 patients with acquired immunodeficiency syndrome complicated with disseminated nontuberculous mycobacterial disease / 中华传染病杂志

Objective:To explore the clinical and laboratory characteristics of acquired immunodeficiency syndrome (AIDS) patients complicated with disseminated nontuberculous mycobacterial (NTM) disease, in order to provide basis for clinical therapy.Methods:The clinical findings, imaging and etiological data of the 71 AIDS patients complicated with disseminated NTM disease admitted to Beijing You′an Hospital from June 2016 to June 2021 were retrospectively analyzed.Results:Among 71 patients with disseminated NTM disease, the most common initial symptom was fever, followed with cough, expectoration, fatigue, poor appetite, abdominal pain and diarrhea. Seventy point four percent (50/71) of these patients had at least two comorbidities, with oral candida infection, cytomegalovirus infection, syphilis, pneumocystis pneumonia and bacterial pneumonia being the most common. Hemoglobin ((87.8±24.2) g/L) and albumin ((27.3±7.0) g/L) levels significantly decreased, while erythrocyte sedimentation rate ((59.8±28.6) mm/1 h) and C-reactive protein ((74.7±50.8) mg/L) levels increased in most cases. The median CD4 + T lymphocyte count was 7×10 6/L. The median time of positive blood culture of NTM was 260 h. Among the 71 patients, 40 cases (56.3%) were infected with Mycobacterium avium, 15 cases (21.1%) with Mycobacterium intracellulare, 10 cases (14.1%) with Mycobacterium colombiense, three cases (4.2%) with Mycobacterium marseillense and three cases (4.2%) with Mycobacterium kansasii.The frequent imaging findings were patchy and nodular shadows in lungs, and most patients had mediastinal or hilar lymph node enlargement and splenomegaly. Conclusions:AIDS complicated with disseminated NTM disease is prevalently occurred in patients with severe immune deficiency, and most of the bacteria belong to the Mycobacterium avium- intracellulare complex. Early obtaining positive etiological results of NTM is essential to guide the correct clinical diagnosis and accurate treatment.

Coagulation factor XII deficiency: Clinical report of 7 patients and literature review / 中国输血杂志

【Objective】 To retrospectively analyze the clinical manifestations and laboratory characteristics of 7 patients with coagulation factor Ⅻ deficiency in our hospital from February 2016 to January 2020 in order to improve the understanding of diagnosis and treatment for the diseases. 【Methods】 The clinical data of 7 patients with coagulation factor Ⅻ deficiency were analyzed, and related literatures were reviewed. 【Results】 All the 7 patients showed significantly prolonged APTT without bleeding or thrombosis. Among them, 1 had a positive family history, and 1 acquired coagulation factor Ⅻ deficiency secondary to the tumor. 【Conclusion】 It is very necessary to comprehensively screen related internal and external coagulation factors and acquired factors in patients with prolonged APTT but no bleeding, so as to avoid missed diagnosis, misdiagnosis and over treatment.

Mieloma múltiplo: características clínicas e laboratoriais ao diagnóstico e estudo prognóstico / Multiple myeloma: clinical and laboratory characteristics in the diagnosis and prognostic study

O mieloma múltiplo (MM) caracteriza-se por expansão clonal plasmocitária na medula óssea e produção de imunoglobulina monoclonal, promovendo progressivamente destruição óssea, falência renal, supressão da hematopoiética e infecções. A identificação de fatores clínicos e laboratoriais ao diagnóstico é importante para predizer sobrevida. O sistema de estadiamento de Durie e Salmon (1975) é o mais utilizado e baseia-se na correlação entre parâmetros clínico-laboratoriais à massa tumoral. A combinação de β2 microglobulina e albumina sérica resultou em um sistema de estadiamento simples e confiável, conhecido como Sistema Internacional de Estadiamento (ISS), que tem sido reconhecido atualmente. O objetivo deste trabalho foi analisar as características clínicas e laboratoriais, ao diagnóstico, de pacientes portadores de MM e estudo de sobrevida. Realizou-se estudo de coorte não concorrente de 101 pacientes portadores de MM atendidos no Serviço de Hematologia do Hospital das Clínicas da UFMG, que receberam diagnóstico no período de abril de 1994 a 31 de outubro de 2006, através da coleta de dados contidos em prontuários médicos. Os pacientes foram acompanhados até maio de 2007. Foi feita análise descritiva das características ao diagnóstico e estudo de sobrevida, utilizando-se análise univariada pela técnica do produto-limite de Kaplan & Meier e teste de Log-Rank para comparação das curvas; já na análise multivariada, utilizou-se regressão múltipla de Cox. A mediana de idade dos pacientes foi de 63 anos de idade, 47,5 por cento eram homens e 52,5 por cento mulheres, sendo 50,6 por cento brancos, 33,3 por cento negros e 16,1 por cento pardos. Manifestações clínicas mais comuns foram: dor óssea (83,2 por cento), fraqueza (70,3 por cento) e perda de peso (40,6 por cento). Radiografia de esqueleto mostrou alterações em 83,8 por cento dos casos. Em relação ao sistema de estadiamento proposto por Durie & Salmon, 63 (62,4 por cento) pacientes...

Multiple myeloma (MM) is characterized by plasmocyte expansion in the bone marrow and the production of monoclonal immunoglobulin, causing bone destruction, renal failure, hematopoietic suppression and infections. Identification of clinical and laboratory factors in the diagnosis are important to predict survival. The Dürie/Salmon staging system, used for the disease, is based on the correlation of clinical and laboratory parameters on tumoral mass. Studies of the combination of β2 microglobulin and albumin resulted in a simple staging system, known as the International Staging System (ISS), which is currently being used. The objectives of this work were to analyze clinical and laboratory characteristics in the diagnosis of MM patients and a study of survival. A non-competitive cohort study was performed of 101 MM patients attended in the Hematology Service/Hospital das Clínicas-UFMG who were diagnosed in the period of April 1994 to October 2006.A descriptive analysis of the characteristics at diagnosis and a study of survival were made. The descriptive analysis was achieved using the Kaplan-Meier technique and the Log-Rank test utilized for a comparison of survival curves. The Cox regression test was used for multivariate analysis. The average age of the patients was 63 years, 47.5 percent were men and 52.5 percent women, with 50.6 percent being white, 33.3 percent black and 16.1 percent mulattos. The most common clinical manifestations were: bone pain (83.2 percent) and weakness (70.3 percent). Radiographies of the skeleton showed alterations in 83.8 percent of the cases. In respect to the Dürie/Salmon staging system, 63 (62.4 percent) patients were in stage III, 32 (31.7 percent) in stage II and 6 (5.9 percent) in stage I. Using the ISS classification, 22 (30.1 percent) patients were in stage III, 31 (42.5 percent) in stage II and 20 (27.4 percent) in stage I. Overall survival was 66.52 months with a follow-up of 20 months. In...
