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)
OBJECTIVE To describe the extrarenal symptoms and clinical course of Henoch-Schönlein purpura (HSP). DESIGN A prospective national multicentre trial with 6-month follow-up. Patients A total of 223 newly diagnosed paediatric HSP patients. RESULTS Purpura was the initial symptom in 73% of the patients and was preceded by joint or gastrointestinal(More)
A 2-hour adrenocorticotrophic-hormone (A.C.T.H.) test was given to 23 children in their first attack of idiopathic nephrotic syndrome, after treatment with prednisone according to the schedule of the International Study of Kidney Disease in Children. The length of the first remission was correlated with the response to the postmedication A.C.T.H. test. In(More)
Familial juvenile nephronophthisis (NPH) is an autosomal recessive tubulointerstitial kidney disease associated with formation of medullary and corticomedullary cysts. It progresses to end stage renal failure and its biochemical defect is unknown. An NPH locus has been assigned to a 2 cM interval on chromosome 2q13 by linkage studies. Homozygous deletions(More)
The effect of age on compensatory hypertrophy and functional adaptation to loss of 75 percent of renal mass was studied in canine puppies. In one group of animals the surgery was done between 1-5 days after birth and in another group, at two months of age. All animals were studied six weeks later. Shamoperated littermates served as controls. The newborn(More)
Interstitial nephritis was diagnosed at renal biopsy in 10 previously healthy children. All had identical clinical symptoms: anaemia, raised sedimentation rate, low glomerular filtration rate, protein and leucocytes in the urine, but no bacteria; nine also had glycosuria. Six of the children had a history of recent ingestion of drugs or a serologically(More)
