Abstract:

Objective

To observe the therapeutic effects of lienal polypeptide injection in the adjunctive treatment of childhood Henoch-Schonlein purpura nephritis (HSPN).

Methods

Children with first onset HSPN with mild to severe proteinuria [>25 mg/(kg·24 h)] diagnosed by renal biopsy within 8 weeks at Children's Hospital of Hebei Province from January 2017 to December 2018 were collected and divided randomly into either an observation group or a control group. Both groups were treated with glucocorticoid and cyclophosphamide, and the observation group was additionally given lienal polypeptide injection. The efficacy and safety were compared between the two groups.

Results

Sixty cases were collected finally with 30 cases in each group. At 4 weeks after treatment, there was no difference in the overall effective rate between the two groups (80.0% vs 70.0%, P>0.05). While at 8 weeks and 6 months after treatment, the overall effective rates of the observation group were significantly higher than those of the control group (93.3% vs 80.0%, χ2=8.665, P=0.003; 100.0% vs 90.0%, χ2=10.526, P=0.001). The infective rate of the observation group was significantly lower than that of the control group (χ2=20.454, P<0.001); there were three (10.0%) infected cases in the observation group and 9 (30.0%) infected cases in the control group in the 8 weeks of acute duration. No adverse events were observed in the observation group.

Conclusion

Lienal polypeptide injection is effective and safe in the adjunctive therapy of childhood HSPN, which can reduce the infective rate and increase the effective rate by improving the immune function.
