RESUMO
Objective:To investigate the efficacy and safety of plasma exchange(PE) in the treatment of autoimmune hemolytic anemia in children.Methods:The data from 8 hospitals in China during November 2014 to April 2017 were collected, and the clinical characteristics of PE in children with AHA were analyzed retrospectively.Results:A total of 21 children with AHA were included in the study, including 17 cases from PICU and 4 cases from pediatric kidney ward, with 11 boys and 10 girls, and the median age was 3.64(0.25, 11.10)years old, and median hospital stay was 12(4, 45)days.There were 15 cases(71.4%) with infection, 2 cases(9.5%)with autoimmune diseases, 4 cases(19.0%) with unknown.Consciousness disturbance occurred in 4 patients before replacement and recovered to normal after PE.The volume of blood decreased in two cases(9.5%) and completely relieved.There were 20 cases of anemia (95.2%), 15 cases were normal after PE, and 5 cases were improved.Jaundice occurred in 18 cases (85.7%), 12 cases were normal after PE, 6 cases were improved.Hepatosplenomegaly was found in 11 cases, 10 cases were normal after PE, 1 case was improved.After PE, the hemoglobin and red blood cell count increased, while the total bilirubin, indirect bilirubin, urea nitrogen and lactate dehydrogenase decreased, there were significant differences between pre-and post-replacement ( P<0.05). Only 1 case had allergic reaction, which was improved after symptomatic treatment, and PE was continued.After PE, 2 cases (9.5%) had complete remission, 16 cases (76.2%) had partial remission and 3 cases (14.3%) had been discharged. Conclusion:PE therapy can obviously improve the clinical symptoms and laboratory indexes of children with AHA who have failed to respond to conservative treatment.It can be used as a treatment measure for children with severe AHA and has a good safety.

RESUMO
Objective:To analyze the clinical characteristics of severe adenovirus pneumonia with bacterial infection in children, so as to provide clinical evidences for early diagnosis and reliable treatment.Methods:A total of 72 pediatric cases with severe adenovirus pneumonia admitted to Pediatric Intensive Care Unit at the First People′s Hospital of Chenzhou from January 2018 to August 2019 were included.The clinical features, laboratory and imaging data, efficacy of the treatments and prognosis were investigated retrospectively.Patients were divided into with bacterial infection group and without bacterial infection group.The clinical characteristics were analyzed.Results:Among the 72 children, there were 54 males and 18 females, aging from 3 months to 5 years, including 37cases with bacterial infection and 35 cases without bacterial infection.Compared with the group without bacterial infection, the group with bacterial infection had longer heat duration and hospital stay [12.0 (10.0, 18.5) days vs.10.0 (9.0, 12.0) days; 6.0(4.0, 7.0) days vs.11.0(6.5, 16.0) days, P<0.05], the incidences of diarrhea and hepatomegaly were higher[35.1% (13/37) vs.14.3%(5/35); 45.9%(17/37)vs.8.6%(3/35), P<0.05], the proportion of five lobes involved in lung imaging was higher [91.8% (34/37) vs. 57.1%(20/35), P<0.05]. The incidences of complications with respiratory failure, hemophagocytic lymphohistiocytosis, and bronchiolitis obliterans in the group with bacterial infection were significantly higher than those of without bacterial infection group ( P<0.05). Conclusion:For children under 2 years old age with severe adenovirus pneumonia, there are prolonged high fever and extensive pulmonary lesions.We should be highly alert to the combination of bacterial infection and timely anti-infection therapy.Children with severe adenovirus pneumonia with bacterial infection have severe clinical manifestations and many complications with respiratory failure, hemophagocytic lymphohistiocytosis, and bronchiolitis obliterans.
