OBJECTIVES: To investigate the difference in the therapeutic effect of mycophenolate mofetil (MMF) or cyclophosphamide (CTX) in children with Henoch-Schönlein purpura nephritis (HSPN) of different age groups. METHODS: A retrospective analysis was conducted on the clinical data of 135 children with HSPN who were treated with MMF or CTX in the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics, from October 2018 to October 2020. According to the immunosuppressant used, they were divided into two groups: MMF group and CTX group, and according to the age, each group was further divided into two subgroups: ≤12 years and >12 years, producing four groups, i.e, the ≤12 years MMF subgroup (n=30), the >12 years MMF subgroup (n=15), the ≤12 years CTX subgroup (n=71), and the >12 years CTX subgroup (n=19). All children were followed up for at least 12 months, and the above groups were compared in terms of clinical outcomes and the incidence rate of adverse reactions. RESULTS: There was no significant difference in the complete response rate between the MMF group and the CTX group after 3, 6, and 12 months of treatment (P>0.05). There were no significant difference in the complete response rate and the incidence rate of adverse reactions between the >12 years MMF subgroup and the ≤12 years MMF subgroup at 3, 6, and 12 months of treatment (P>0.05). The >12 years CTX subgroup had a significantly lower complete response rate than the ≤12 years CTX subgroup at 6 and 12 months of treatment (P<0.05). The >12 years CTX subgroup had a significantly higher incidence rate of adverse reactions than the >12 years MMF subgroup (P<0.05). CONCLUSIONS: The efficacy and adverse reactions of MMF are not associated with age, but the efficacy of CTX is affected by age, with a higher incidence rate of adverse reactions. CTX should be selected with caution for children with HSPN aged >12 years.

Clinical effect of different prednisone regimens in the treatment of children with primary nephrotic syndrome and risk factors for recurrence. / ä¸åŒæ–¹æ¡ˆæ³¼å°¼æ¾æ²»ç–—å„¿ç«¥åŽŸå‘æ€§è‚¾ç— ç»¼åˆå¾çš„ç–—æ•ˆåŠå¤å‘å±é™©å› ç´ åˆ†æž.

OBJECTIVES: To study the clinical effect of full-dose prednisone for 4 or 6 weeks in the treatment of children with primary nephrotic syndrome and its effect on recurrence. METHODS: A prospective non-randomized controlled clinical trial was performed on 89 children who were hospitalized and diagnosed with incipient primary nephrotic syndrome from December 2017 to May 2019. The children were given prednisone of 2 mg/(kg·day) (maximum 60 mg) for 4 weeks (4-week group) or 6 weeks (6-week group), followed by 2 mg/(kg·day) (maximum 60 mg) every other day for 4 weeks and then a gradual reduction in dose until drug withdrawal. The children were regularly followed up for 1 year. The two groups were compared in terms of the indices including remission maintenance time and recurrence rate. A Cox regression analysis was used to assess the risk factors for recurrence. RESULTS: Within 3 months after prednisone treatment, the 4-week group had a significantly higher recurrence rate than the 6-week group (P<0.05). After 1-year of follow-up, there was no significant difference between the two groups in the recurrence rate, remission maintenance time, and recurrence frequency (P>0.05). The risk of recurrence increased in children with an onset age of ≥6 years or increased 24-hour urinary protein (P<0.05). CONCLUSIONS: For the treatment of incipient primary nephrotic syndrome, full-dose prednisone regimen extended from 4 weeks to 6 weeks can reduce recurrence within 3 months. The children with an onset age of ≥6 years or a high level of urinary protein should be taken seriously in clinical practice, and full-dose prednisone treatment for 6 weeks is recommended to reduce the risk of recurrence.

[Efficacy and safety of mycophenolate mofetil versus cyclophosphamide in the treatment of Henoch-Schönlein purpura nephritis with nephrotic-range proteinuria in children: a prospective randomized controlled trial].

OBJECTIVE: To study the efficacy and safety of mycophenolate mofetil (MMF) versus cyclophosphamide (CTX) in the treatment of children with Henoch-Schönlein purpura nephritis (HSPN) and nephrotic-range proteinuria. METHODS: A prospective clinical trial was conducted in 68 pediatric patients who were admitted to the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics and who were diagnosed with HSPN and nephrotic-range proteinuria from August 2016 to November 2019. The patients were randomly divided into two groups:MMF treatment (n=33) and CTX treatment (n=35). The two groups were compared in terms of complete remission rate, response rate (complete remission + partial remission), urinary protein clearance time, and adverse events. RESULTS: At months 3, 6, and 12 of treatment, there was no significant difference in the complete remission rate and the response rate between the MMF treament and CTX treatment groups (P > 0.05). There was also no significant difference between the two groups in the urinary protein clearance time and the incidence rate of adverse events (P > 0.05). CONCLUSIONS: MMF and CTX have similar efficacy and safety in the treatment of HSPN children with nephrotic-range proteinuria.

[A prospective, randomized, controlled clinical study of Huai Qi Huang granules in treatment of childhood primary nephrotic syndrome].

OBJECTIVE: To study the efficacy of Huai Qi Huang granules in the treatment of childhood primary nephrotic syndrome. METHODS: Between July 2009 and December 2011, patients who were admitted and diagnosed for the first time as childhood primary nephrotic syndrome were randomized into a treatment group (Huai Qi Huang granules plus glucocorticoid; n=23) and a control group (glucocorticoid alone; n=19) for a prospective study. The two groups were compared for regression time of edema, time to urinary protein clearance, relapse rate, incidence of infection, dosage of glucocorticoid, and humoral and cellular immunological indicators. RESULTS: There were no significant differences in regression time of edema, time to urinary protein clearance, and relapse rate between the treatment and control groups (P>0.05). The treatment group had significantly lower incidence of infection and daily dose of glucocorticoid (at month 6) than the control group (P<0.05). Humoral and cellular immunological indicators showed no significant differences between the two groups (P>0.05). No Huai Qi Huang-related adverse events were observed in this study. CONCLUSIONS: Huai Qi Huang granules treatment can reduce the dose of glucocorticoid and the incidence of infection in children with primary nephrotic syndrome and has a favourable safety.
