ABSTRACT
Abstract Objective: The aim of this study is to define the predictors of chronic carditis in patients with acute rheumatic carditis (ARC). Methods: Patients diagnosed with ARC between May 2010 and May 2011 were included in the study. Echocardiography, electrocardiography, lymphocyte subset analysis, acute phase reactants, plasma albumin levels, and antistreptolysin-O (ASO) tests were performed at initial presentation. The echocardiographic assessments were repeated at the sixth month of follow-up. The patients were divided into two groups according to persistence of valvular pathology at 6th month as Group 1 and Group 2, and all clinical and laboratory parameters at admission were compared between two groups of valvular involvement. Results: During the one-year study period, 22 patients had valvular disease. Seventeen (77.2%) patients showed regression in valvular pathology. An initial mild regurgitation disappeared in eight patients (36.3%). Among seven (31.8%) patients with moderate regurgitation initially, the regurgitation disappeared in three, and four patients improved to mild regurgitation. Two patients with a severe regurgitation initially improved to moderate regurgitation (9.1%). In five (22.8%) patients, the grade of regurgitation [moderate regurgitation in one (4.6%), and severe regurgitation in 4 (18.2%)] remained unchanged. The albumin level was significantly lower at diagnosis in Group 2 (2.6 ± 0.48 g/dL). Lymphocyte subset analysis showed a significant decrease in the CD8 percentage and a significant increase in CD19 percentage at diagnosis in Group 2 compared to Group 1. Conclusion: The blood albumin level and the percentage of CD8 and CD19 (+) lymphocytes at diagnosis may help to predict chronic valvular disease risk in patients with acute rheumatic carditis.
Resumo Objetivo: Definir os preditores da cardite crônica em pacientes com cardite reumática aguda (CRA). Métodos: Os pacientes diagnosticados com CRA entre maio de 2010 e maio de 2011 foram incluídos no estudo. Foram feitos os testes de ecocardiografia, eletrocardiograma, uma análise do subgrupo de linfócitos, provas de fase aguda, níveis de albumina plasmática, antiestreptolisina-O (ASO) na manifestação inicial. As avaliações ecocardiográficas foram repetidas no 6º mês de acompanhamento. Os pacientes foram divididos em dois grupos de acordo com a persistência da patologia valvular no 6º mês como Grupo 1 e Grupo 2 e todos os parâmetros clínicos e laboratoriais na internação foram comparados entre dois grupos de comprometimento valvular. Resultados: Durante o período do estudo de um ano, 22 pacientes apresentaram doença valvular; 17 (77,2%) apresentaram regressão da patologia valvular. Houve desaparecimento de regurgitação moderada inicial em oito pacientes (36,3%). Entre sete (31,8%) pacientes com regurgitação moderada inicialmente, a regurgitação desapareceu em três e quatro apresentaram melhoria para regurgitação leve. Dois pacientes com regurgitação grave inicialmente apresentaram melhoria para regurgitação moderada (9,1%). Em cinco (22,8%) pacientes o grau de regurgitação (regurgitação moderada em um [4,6%] e regurgitação grave em quatro [18,2]) continuou inalterado. O nível de albumina foi significativamente menor no diagnóstico no Grupo 2 (2,6 ± 0,48 gr/dL). A análise do subgrupo de linfócitos mostrou uma redução significativa no percentual de CD8 e um aumento significativo no percentual de CD19 no Grupo 2 em comparação com o Grupo 1. Conclusão: O nível de albumina no sangue e o percentual de linfócitos CD8 e CD19 (+) no diagnóstico podem ajudar a prever risco de doença valvular crônica em pacientes com cardite reumática aguda.

Objective To research the mechanism of the changes of T lymphocyte subtypes and provide reference for clinically prevention,diagnosis and treatment for NSCLC through analysis of the expression of Th1 ,Th2 in Non-small-cell carcinoma (NSCLC)patients.Methods Whole blood (EDTA anticoagulant treatment)from 60 NSCLC patients and 60 healthy sub-j ects were collected to detect of the expression of CD3 +T cells,CD4+T cells and CD8+T cells on T lymphocytes and the lev-els of Th1 and Th2 cells by flow cytometer (FCM),and the absolute value of T lymphocyte by hematology analyzer.Results Compared with normal control group,after surgery 1~3 days NSCLC groups,the percent of CD3 +T,CD4+T,CD8+T cells and the CD4+/CD8+ ratio in the NSCLC patients before surgery were significantly reduced 58.40±10.27 vs 66.58± 6.84,31.32±8.65 vs 39.40±6.43,34.23±8.00 vs 24.31±8.16,0.96±0.23 vs 1.58±0.23 (t=-6.726~14.916,P<0.05).The percent of CD3 +T,CD4+T,CD8+T cells and the CD4+/CD8+ ratio in the NSCLC patients after surgery 1~3 days were also significantly decreased 56.31±8.00 vs 66.58±6.84,27.72±7.55 vs 39.40±6.43,33.69±7.10 vs 24.31± 8.16,0.87±0.31 vs 1.58±0.23 (t=-6.720~14.367,P<0.05).The percent of CD4+T cells in the NSCLC patients af-ter surgery 4~7 days was increased 33.23±4.13 vs 39.40±6.43(t=6.257,P<0.05).Compared with the control group, within the helper T cell subsets,the cell content of Th1,Th2 cells (× 10/μl)and the Th1/Th2 ratio were significantly changed in different extent in the NSCLC group before surgery 6.79±1.34 vs 12.52±3.56,4.82±0.51 vs 2.32±0.82, 1.39±0.84 vs 5.36±1.42 (t=-20.087~18.630,P<0.05).The content of Th1 cells was lower in the NSCLC patients after 1~3 days and 4~7 days 8.86±1.52 vs 12.52±3.56,7.02±1.27 vs 12.52±3.56 (t=7.339~11.275,P<0.05). Conclusion The NSCLC patients presented immune dysfunction,like T lymphocytes and helper T cells decreased and Th2 cells were clearly in the ascendant.Also,the cytotoxic T cells increased by the stimulation of cancer cells,but they began to decrease after the surgery.
