Abstract:
Objective:To assess the efficacy and safety of Tacrolimus(TAC)in combination with glucocorticosteroid(GC)for treating IgA vasculitis nephritis(IgAVN)in children.Methods:A retrospective analysis was conducted on pediatric patients who were diagnosed with IgAVN from January 2015 to January 2022 in Children's Hospital of Hebei Province.The patients presented with nephrotic-range proteinuria or persistent urine protein(>0.5g/24 h)despite adequate glucocorticoid and other treatments in patients who do not reach massive proteinuria levels.They were treated with TAC combined with GC. The following laboratory parameters were obtained for outcome assessment: 24-hour urinary protein excretion, serum albumin, serum creatinine levels, and fasting blood glucose measurements. The efficacy and adverse reactions of TAC were summarized.Results:A total of 97 children (55 males and 42 females) were included. The average age of diagnosis of IgA vasculitis was (8.65±2.46) years, and 95.9% of the children developed renal involvement within 30 days after diagnosis. Pathological examination of renal puncture: 5 cases of grade Ⅱa, 2 cases of grade Ⅱb, 31 cases of grade Ⅲa, 57 cases of grade Ⅲb, and 2 cases of grade Ⅳb.Remission rate at 3 months was 96.9%(94/97).Three patients failed to achieve clinical remission who were treaed with other immunosuppressants.After 1, 3, 6 and 12 months of TAC treatment, the urine protein levels of 94 children were lower than those before treatment, and the differences were statistically significant ( P < 0.05), showing a gradual downward trend. Serum albumin levels were higher than those before treatment, and the differences were statistically significant ( P < 0.05), showing a gradual upward trend.After 3 months and 6 months of TAC treatment, the serum creatinine and fasting blood glucose of the children increased. With the remission of the disease, TAC dosage decreased, the mean values of serum creatinine and fasting blood glucose decreased after 12 months of treatment.The average treatment time of TAC was (10.8±2.6) months, the average follow-up time was (3.33±1.56) years, and the longest follow-up time was 8 years. During the follow-up period, there were no serious adverse reactions such as gastrointestinal discomfort, liver function damage and severe infection. After stopping GC and TAC treatment, 80 children got sustained remission. Conclusion:The combination of TAC and GC has been proved to be effective in treating IgAVN in children.The overall effective rate is high,and clinical remission can be achieved quickly with relatively mild adverse reactions.
