RESUMO

OBJECTIVES@#Based on peripheral blood lymphocyte subsets and common laboratory test indexes, this study aimed to construct a predictive scoring system for intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD).@*METHODS@#Children hospitalized in Tianjin Children's Hospital from January 2021 to March 2023 were included in the study (185 cases of IVIG-sensitive KD and 41 cases of IVIG -resistant KD). Forty-six healthy children matched for age and gender were selected as controls. The relative percentage and absolute counts of peripheral lymphocyte subsets were measured by flow cytometry. Multivariate logistic regression was used to identify the predictive factors for IVIG-resistant KD and to construct a predictive scoring system for predicting IVIG-resistant KD.@*RESULTS@#The multivariate logistic regression analysis showed that CD4+ T cell absolute count, natural killer cell absolute count, serum sodium level, globulin level, and total bilirubin level were identified as predictive factors for IVIG-resistant KD (P<0.05). The predictive scoring system based on these factors achieved a sensitivity of 70.7% and a specificity of 83.8% in predicting IVIG-resistant KD.@*CONCLUSIONS@#Peripheral blood lymphocyte subsets can serve as predictive indicators for IVIG-resistant KD in children. The introduction of this indicator and the establishment of a scoring system based on it can provide a higher accuracy in predicting IVIG-resistant KD in children.

RESUMO

Objective To observe the change of peripheral blood lymphocytes subsets in patients with active ulcerative colitis (UC) and explore its clinical significance. Methods The clinical data and lymphocyte subsets of 40 active UC patients who admitted to the Department of Gastroenterology, Peking University First Hospital,from June 2007 to January 2010 were retrospectively analyzed. Patients who had previously used immunosuppressants or tumor necrosis factor monoclonal antibody were excluded. Seventy-nine subjects with health examination served as controls. Peripheral blood lymphocyte subsets detected included total T cells, CD4 + T cells, CD8 + T cells, B cells, and NK cells. Only the first detection results of UC patients were used for analysis. Results The proportion of total T cells for UC patients (73.60% ± 8.35% ) was significantly higher than the controls (69. 76% ±7.37%) (P =0.012). CD8+T cell ratio (35.53% ± 10.99%) was significantly higher than the controls ( 30. 56% ± 6. 75 % ) ( P = 0. 011 ). When the UC patients were stratified according to inflammatory involvement,the total T cells, CD8 +T cell, and NK cell ratio were significantly different among pancolitis, non-pancolitis, and the controls ( all P < 0. 05 ). When the UC patients were stratified according to the disease course, the total T cells and CD8 + T cell ratio were significantly different among chronic recurrent/persistent, onset, and the controls ( both P < 0.05 ). When the UC patients were stratified according to the extraintestinal manifestations, the total T cells and CD8 + T cell ratio were significantly different among those with extraintestinal manifestations, those without extraintestinal manifestations, and the controls ( both P < 0.05 ). Conclusions The proportion of total T cells and CD8 + T cells increase in UC patients. Such immune abnormalities are even more distinctive in those UC patients who suffer from pancolitis or chronic recurrent/persistent type or those with extraintestinal manifestations.
