BACKGROUND Henoch-Schönlein purpura arising in childhood could cause renal impairment or even an end-stage renal disease later in life. We aimed to assess long-term outcome of childhood Henoch-Schönlein purpura after 24 years. METHODS We studied a cohort of 26 boys and 26 girls who were treated for Henoch-Schönlein purpura at Helsinki University Hospital(More)
An unselected population of 8,954 children, age 8 to 15 years, was screened for hematuria. Four urine specimens from each were examined; microscopic hematuria was found in one or more specimens in 4.1%, and in two or more specimens in 1.1% of the children. The prevalence was not age or sex dependent. Those with two or more positive samples were re-examined(More)
OBJECTIVE To evaluate the efficacy of early prednisone therapy in preventing renal and treating extrarenal and renal symptoms in Henoch-Schönlein purpura (HSP) in a placebo-controlled trial. STUDY DESIGN A total of 171 patients (84 treated with prednisone and 87 receiving placebo) were included and followed up for 6 months. The endpoints were renal(More)
A total of 532 children, 401 from Europe and 131 from the United States, was recruited into an international multicenter study comparing the results of medical and surgical treatment of children with international grade III or IV vesicoureteral reflux and urinary tract infection. Patient age was less than 11 years, glomerular filtration rate was greater(More)
Progressive glomerulonephritis is the most serious feature of Henoch-Schönlein syndrome. In a series of 141 children with Henoch-Schönlein purpura 39 (28%) had abnormal urinary sediment for a duration of more than one month. This subgroup was followed up for 3.0 to 13.8 (mean 7.2) years. One child progressed to renal failure and 2 developed chronic(More)
PATIENTS AND METHODS All children with Henoch-Schoenlein glomerulonephritis (HSP-GN) and nephrotic-range proteinuria (> 40 mg/h/m2), treated at 5 university hospitals and in 1 central hospital in Finland during in 1990-1997, were analyzed retrospectively. The mean age of these 19 patients (8 girls, 11 boys) at the time of diagnosis was 9.9 years (range(More)
One hundred and fourteen children with primary nephrotic syndrome were followed up prospectively for periods of between 5 and 14 years. Urine samples from 94 of them became protein-free during the initial 8-week course of prednisone, and the outcome for these children was good: 74 of them have been free of symptoms for at least 3 years, 18 have had relapses(More)
We evaluated the natural long-term outcome after childhood IgA nephritis. Altogether 55 patients with biopsy-proven IgA nephritis were identified, 37 (67%) responded to the health questionnaire and 31 (56%) participated in the medical examination after a mean follow-up of 18.7 years (SD 6.2; range 8.5–29.8). The results of medical examination, onset data(More)
OBJECTIVE To assess the risk factors for developing Henoch-Schönlein purpura nephritis (HSN) and to determine the time period when renal involvement is unlikely after the initial disease onset. DESIGN A prospective study of 223 paediatric patients to examine renal manifestations of Henoch-Schönlein purpura (HSP). The patient's condition was monitored with(More)
