Insights
Cesarean delivery (CS) is linked to a higher risk of relapse in children with idiopathic nephrotic syndrome (INS). This finding suggests a potential connection between birth method and disease recurrence in pediatric nephrology.
Area of Science:
- Pediatric Nephrology
- Obstetrics and Gynecology
Background:
- Childhood chronic diseases are increasing.
- Cesarean delivery rates have also risen significantly.
- The relationship between cesarean delivery and idiopathic nephrotic syndrome (INS) relapse is unclear.
Purpose of the Study:
- To investigate the hypothesis that cesarean section (CS) delivery increases the risk of relapse in children with INS.
- To analyze the association between birth by CS and the frequency of INS relapses.
Main Methods:
- A cohort of 56 children diagnosed with INS was studied.
- Patients were categorized into three groups based on relapse frequency: no relapse (Group A), infrequent relapse (Group B), and frequent relapse (Group C).
- The proportion of births via CS was compared across these groups.
Main Results:
- Group C (frequent relapse) had a significantly higher CS rate (37.5%) compared to Group A (0%) and Group B (7.1%).
- A statistically significant association (P < 0.001) was found between CS delivery and frequent relapses of INS.
- No children in the no-relapse group were delivered by CS.
Conclusions:
- Cesarean delivery is associated with an increased risk of relapse in childhood idiopathic nephrotic syndrome.
- Further research is warranted to understand the underlying mechanisms connecting CS and INS relapse.
- This finding may inform clinical management and counseling for families affected by INS.
Abstract:
In parallel with the increase in the prevalence of childhood chronic diseases, the rate of cesarean delivery has risen during the past decades. This study tested the hypothesis that children delivered by cesarean section (CS) have a higher risk of relapse of idiopathic nephrotic syndrome (INS). Fifty-six children with INS were categorized into three groups. Group A consisted of patients with INS who had no relapses after the onset of INS; group B consisted of patients with INS who had infrequent relapse; and group C consisted of patients with INS who had frequent relapse. The number of enrolled patients in groups A, B, and C was 10, 14, and 32, respectively. The ratio of neonates delivered via CS was significantly higher in group C (37.5%, P < 0.001) than in groups A (0%) and B (7.1%). This study shows that CS is associated with an increased risk of relapse of childhood INS.
