    Abstract:
    BACKGROUND: Intrauterine growth restriction seems to be a risk factor for an aggravated course of secondary renal diseases in children. Catch-up growth after birth may play a critical role. We tested if there is an association between an aggravated course of nephritis in Henoch-Schönlein Purpura (PSHN) and low birth weight or early weight gain during infancy. PATIENTS: We retrospectively analysed the clinical course of 34 children with PSHN. METHODS: Patients were sorted according their birth weight standard deviation score (SDS) in tertiles. Early weight gain was defined as gain of weight standard deviation score >0.67 between birth and 2 years of age. RESULTS: Patients with higher birth weight needed Cyclophosphamide in a higher rate than low birth weight children. In the high weight gain group (SDS gain >0.67) 9 of the 11 patients compared to 7 of 22 patients in the low weight gain group (SDS gain <0.67) presented with arterial hypertension during the initial manifestation of PSH nephritis (p=0.01). Median systolic blood pressure SDS in the high weight gain group was 1.54 (-1.39-4.71) versus 0.29 (0.52-4.05) in the low weight gain group (p=0.008). Nevertheless, other clinical parameters during first manifestation and follow-up were not relevantly different. CONCLUSION: In contrast to the data of children with idiopathic nephrotic syndrome or IgA nephropathy, this study does neither provide evidence for an association between low birth weight nor early weight gain and the later course of PSHN. Interestingly, early weight gain was associated with a higher systolic blood pressure during the initial manifestation of PSHN.
