BACKGROUND: Although clinical and immunological studies have shown a possible link between allergy and idiopathic nephrotic syndrome (INS), the nature of the relationship remains unclear. Asthma is the most common chronic allergic airway inflammation. However, no study has used a longitudinal design with a population cohort to investigate INS in children with asthma.
METHODS: Using nationwide claims data from 2000 through 2007, we randomly selected 251,698 asthma cases and 1,006,791 frequency-matched controls. Incidence rates of INS and hazard ratios (HRs) were calculated.
RESULTS: The INS incidence was 3.36-fold greater in the asthma cohort than in the nonasthma control (9.26 vs. 2.76 per 100,000 person-years; 95% confidence interval (CI): 2.65-4.26). The HR for INS increased for those with more asthma-related medical visits per year, from 1.49 (95% CI: 1.06-2.11) for <3 visits to 15.7 (95% CI: 11.5-21.5) for ≥6 visits (trend test, P < 0.0001). The HR for INS slightly decreased during the follow-up period, from 3.41 (95% CI: 2.66-4.38) for ≤5.5 y to 2.90 (95% CI: 1.33-6.30) for >5.5 y.
CONCLUSION: We conclude that children with asthma had an increased incidence rate of INS, and increased incidence rate correlated with asthma-related medical visits.
