Objectives To review the clinical features in children with methylmalonic academia (MMA) having the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment. Methods The clinical data of 4 children diagnosed of MMA with the primary clinical manifestations of microangiopathic hemolytic anemia and renal impairment were retrospectively analyzed from August 2013 to present. Results In the four children (two boys and two girls) with the age from nine months to three years seven mouths, two children were diagnosed with MMA combined with homocysteine, and 2 children were diagnosed with MMA, but there was no homocysteine testing. All four children showed moderate to severe anemia, proteinuria, hematuria, and hypertension. One child had abnormal renal function and thrombocytopenia, and manifested as hemolytic uremic syndrome. Renal biopsy was performed in 2 children and they had glomerular sclerosis lesions with renal tubular necrosis and mesangial proliferative glomerulonephritis respectively. All children were treated with vitamin B12, and the indexes of microangiopathic hemolytic anemia and renal impairment were improved signiifcantly. Conclusions MMA may be combined with microangiopathic hemolytic anemia, renal impairment and even hemolytic uremic syndrome, and the early diagnosis and treatment is required.

Objective To evaluate the efficacy and safety of tigecycline-based treatment approach on severe infection of patients with hematological diseases. Methods The clinical data of 64 patients who were treated with tigecycline-based treatment approach for severe infection were retrospectively reviewed. The curative effect was evaluated, meanwhile the drug side effects were observed. Results A total of 51 strains of bacteria were isolated from 64 patients, including 12 extended-spectrum β-lactamase(ESBL)and 15 multi-drug resistant strains and the total effective rate was 59.4%(38/64). Five patients diagnosed as carbapenem resistant infection and were treated with the addition dose of tigecycline and 3 patients relieved. Main adverse events were nausea, vomiting, diarrhea and hepatic dysfunction, but all events were slight. Conclusions Tigecycline-based treatment approach has a good clinical efficacy in treating severe infection of patients with hematological diseases, and the side effect is few.Tigecycline-based treatment approach could be used as a new choice for patients non-responding favorably to conventional anti-infective treatment or multiple resistant bacteria.

This article reported a rare case of harlequin ichthyosis which was indicated with multiple structural abnormalities by prenatal ultrasound and diagnosed by trio-based whole-exome sequencing (Trio-WES). Prenatal diagnosis was performed because the ultrasound at 24 +4 gestational weeks revealed the fetus presenting with eclabium, flattened nose, short mandible, small auricle and abnormal posture of the toes. Copy number variation sequencing (CNV-seq) showed no chromosome aneuploidy or pathogenic copy number variants over 100 kb in the fetal or parental samples. Trio-WES showed that the fetus carried two heterozygous mutations, c.2593-1G>A and c.7444C>T in ABCA12. Sanger sequencing confirmed that c.2593-1G>A, a previously unreported variant, was paternally inherited and c.7444C>T was maternally inherited. Both parents had normal phenotype. The fetus was finally diagnosed with harlequin ichthyosis. After prenatal counseling, the parents made an informed choice to terminate the pregnancy at 28 +4 gestational weeks. The stillborn fetus showed multiple malformations The variants in this case expand the spectrum of variants in ABCA12 gene.

Objective:To analyze and summarize the efficacy and safety of thalidomide in the treatment of refractory systemic juvenile idiopathic arthritis(sJIA).Methods:The clinical data of ten patients with refractory sJIA admitted to Department of Nephrology and Immunology in Children's Hospital of Hebei Province from January 2015 to March 2022 were collected,and the clinical manifestations,efficacy and safety of thalidomide in the treatment of refractory sJIA were analyzed retrospectively. Systemic juvenile arthritis disease activity score(sJADAS)was used to evaluate the efficacy of the treatment. Statistical analysis was performed by repeated measurements using general linear models.Results:Among the 10 children(4 males and 6 females)with refractory sJIA,the average age of onset was(7.5±3.3)years. Seven patients were complicated with macrophage activation syndrome at an early stage of disease.The average course of disease was(4.4±1.7)years,and the longest course of disease was 8.3 years. Before the application of thalidomide,all the 10 children experienced relapses(ranging from 2 to 10 times). The indices of 10 children treated with thalidomide at 6 months and 12 months were compared with those before treatment. Peripheral blood leukocytes[(10.19±3.67)×10 9/L,(8.53±2.83)×10 9/L vs.(16.11±7.81)×10 9/L, F=7.918,11.084, P=0.020,0.009],C-reactive protein[19.13(0.38,35.21)mg/L,8.05(0.10,18.00)mg/L vs. 59.34(24.20,131.90)mg/L, F=7.030,12.731, P=0.026,0.006],sJADAS scores[6.00(1.50,12.50)scores,3.00(0,12.50)scores vs. 20.00(11.50,28.00)scores, F=14.710,17.870, P=0.004,0.002]were decreased significantly. The doses of prednisone[0.13(0,0.45)mg/(kg·d),0.02(0,0.06)mg/(kg·d)vs. 0.42(0.16,1.47)mg/(kg·d), F=5.890,7.623, P=0.041,0.022]were significantly decreased.All the differences were statistically significant. Prednisone was successfully discontinued in 7 cases. Tocilizumab was gradually withdrawn in 3 cases,and tocilizumab administration interval was prolonged in 1 case. None of the 10 children had serious adverse reactions. Conclusion:Thalidomide is clinically effective in the treatment of sJIA,and can reduce the required dose of prednisone and prolong the tocilizumab free remission.
