Abstract:
Objective:To analyze the clinical features of severe refractory mycoplasma pneumoniae pneumonia (SRMPP) in children, and explore its risk factors complicated with extrapulmonary organ dysfunction.Methods:The clinical data of children with SRMPP who were admitted to the Department of Critical Care Medicine of Shanghai Children's Hospital from July 2017 to June 2019 were retrospectively summarized. The patients were divided into two groups according to the occurrence of extrapulmonary organ dysfunction: the extrapulmonary organ dysfunction group and the respiratory dysfunction group. The differences of clinical features and laboratory indexes between the two groups were compared, and the risk factors of extrapulmonary organ dysfunction were screened out by logistic regression analysis.Results:A total of 107 cases with SRMPP were admitted to the Pediatric Intensive Care Unit during the past two years, and there were 44 cases (41.1%) complicated with pleural effusion, 17 cases (15.9%) with plastic bronchitis, 104 cases (97.2%) with positive results for macrolide resistance genes (2063, 2064), with an in-hospital mortality rate of 2.8% (3/107). Among 107 children with SRMPP, there were 51 cases (47.7%) with extrapulmonary organ dysfunction, 43 cases (40.2%) with cardiovascular dysfunction, 13 cases (12.1%) with coagulation dysfunction, 11 cases (10.3%) with gastrointestinal dysfunction, 4 cases (3.7%) with renal dysfunction, 4 cases (3.7%) with brain dysfunction, 3 cases (2.8%) with liver dysfunction, and 16 cases (15.0%) with multiple organ dysfunction. Compared with the respiratory dysfunction group, the incidence of capillary leak syndrome was higher (52.9% vs. 17.9%, P < 0.001), the capillary leak index was increased [11.71 (4.63, 27.07) vs. 5.78 (2.07, 15.71), P =0.019], serum albumin was decreased [(32.2 ± 5.6)g/L vs. (34.7 ± 6.7)g/L, P=0. 041], and prothrombin time was prolonged significantly [12.7 (11.7, 13.8)s vs. 12.0 (11.4, 13.0)s, P=0. 009]. Logistic regression analysis showed that capillary leak syndrome ( OR=0. 278, 95% CI 0.102-0.759, P=0. 013) and prolonged prothrombin time ( OR=1. 443, 95% CI 1.018-2.046, P=0. 039) were independent risk factors for SRMPP complicated with extrapulmonary organ dysfunction. Conclusions:Approximately 50% of children with SRMPP have dysfunction of extrapulmonary organs, such as circulation, coagulation and gastrointestinal disorders. Capillary leak syndrome and prolonged prothrombin time are independent risk factors for SRMPP complicated with extrapulmonary organ dysfunction.
