Background:In this study, 66 patients with Henoch-Schonlein nephritis (HSN)
were investigated clinicopathologically.
Methods: The patients were classified according to their initial presentati
on, histologic findings, recurrences of purpura, type of treatment and clin
ical outcome. Logistic regression analysis was performed.
Results: Sixty-eight percent of patients were hospitalized with mild renal
disease. Most patients were evaluated as class I and II according to light
microscopy. In addition to IgA deposition alone. 33% of patients showed IgA
+ C3 and 27% had IgA + IgG + C, depositions. After the follow-up period of
3.3 years, 15 patients had minor urinary findings, 4 had active renal dise
ase and 1 had renal insufficiency Recurrences occurred in 37.9% of patients
and 37.1% of patients with recurrences had persistent pathologic findings.
Symptomatic treatment was given to 51.5% of patients, while 27.2% were giv
en corticotherapy.
Conclusions: Clinical presentation was found to be correlated with outcome.
Recurrence of the disease and the type of the treatment also affected the
outcome. It was also thought that mesangial IgG and C-3 depositions may hav
e a role in the pathogenesis of renal damage in HSN.
