We have observed the occurrence of focal segmental glomerulosclerosis in all three siblings of a single Hispanic family. Each of the children had the onset of significant proteinuria on or before the age of 10. The two oldest children have had progression of their disease to end-stage with subsequent successful transplantation. The youngest sibling continues to have normal renal function. All three patients had renal biopsies prior to the onset of renal insufficiency and each of the biopsies showed the presence of focal segmental glomerulosclerosis with mild diffuse mesangial hypercellularity. Finally, HLA-typing revealed the presence of DRw8 in all three siblings and the father. This report further suggests that genetic factors may be quite important in the development of the lesion of focal segmental glomerulosclerosis.

To define risk factors and markers associated with proliferative retinopathy (PR), we compared 44 insulin-dependent diabetic patients with PR with 45 matched patients without advanced retinopathy (NR). Glycemic control assessed by HbA1 measurements from 5 yr preceding diagnosis of PR was significantly worse than in NR patients. The NR patients had more frequently been treated with multiple daily insulin injections than the PR patients. About half of the PR patients had Albustix-positive proteinuria, and these patients were further characterized by an abnormal lipid profile in plasma and increased frequency of cardiovascular disease. In contrast, PR patients without proteinuria did not differ from NR patients in these variables. Sensorimotor and autonomic neuropathy were twice as frequent in the PR than in the NR group. There was no correlation between anti-insulin antibody titer, immune complexes, and the presence of PR, but T-lymphocyte response to different stimuli was slightly reduced in the PR patients. The anti-insulin-antibody titer correlated with duration of diabetes in the NR but not the PR group. The frequency of HLA-DRw8 was slightly higher in the PR group than in the NR group (16 vs. 0%, NS), but we could not confirm the previously suggested association between HLA-DR4 and PR. Serum C4 levels were low in the diabetics but did not differ between PR patients without proteinuria and NR patients. In conclusion, poor glycemic control was clearly associated with PR in this study, and attempts to prevent this hazardous complication should include means to improve insulin therapy. We did not find support for the view that susceptibility to PR is associated with any known HLA antigen(s).(ABSTRACT TRUNCATED AT 250 WORDS)

This report described 45-year-old identical twin sisters with IgA nephropathy. Case 1 presented with microscopic hematuria and proteinuria at the age of 39. Case 2 was found proteinuria at the age of 32. Both the physical examination and laboratory data of these cases were normal. Serum level of IgA was not elevated. The renal biopsy specimen of two cases showed slight mesangial proliferation by light microscopy and mesangial IgA deposition by immunofluorescence microscopy. Their serotype for HLA was found to be HLA-A2, A24, Bw35, Cw1, Cw3, DRw8, DRw12. Several reports indicated the familial occurrence of patients with IgA nephropathy and a strong association with HLA-Bw35 in those patients. The present cases also suggested that an abnormal immune response-linked HLA system may be involved in the development of IgA nephropathy.

A 50-year-old woman was admitted because of high fever and fatigue. Proteinuria, hematuria, and elevated BUN (47.8 mg/dl) and creatinine (3.4 mg/dl) suggested rapidly progressive glomerulonephritis. The serological study revealed all negative results for rheumatoid factor, antinuclear antibody, serum cryoglobulins, MPO-ANCA, PR3-ANCA, and anti-streptolysin O. Antiglomerular basement membrane (GBM) antibody, as assessed by ELISA, was 11 EU (normal, <10). Kidney biopsy on the eighth hospital day demonstrated pauci-immune-type crescentic glomerulonephritis without ANCA. Methylprednisolone pulse therapy (500 mg/day, 3 days) and 45 mg/day prednisolone orally were started. At 3 weeks after kidney biopsy, the anti-GBM antibody value increased from 11 EU/ml to 116 EU/ml, and MPO and PR3-ANCA were still negative. HLA type was DR8 and DR 15(2), with a genotype of HLA-DRB1*08021 and HLA-DRB1*15011. The present case suggests that HLA-DR15 plays an important role on antibody production against alpha 3(IV) NC1 autoantigen after severe nephritis or tissue damage.
