Unusual glomerulopathy with aggregated subepithelial microspheric particles resembling membranous nephropathy: a variant of glomerulopathy associated with podocytic infolding?

A 69-year-old woman presented with unusual electron microscopic findings. The patient was admitted to ascertain the cause of her persistent proteinuria, and kidney biopsy was performed. While light microscopic findings and immunofluorescence study suggested membranous nephropathy, electron microscopic study showed microspheric particles aggregated in the subepithelial space where electron-dense deposits should have existed.

HLA class II haplotypes associated with pulmonary interstitial lesions of polymyositis/dermatomyositis in Japanese patients.

To elucidate the immunogenetic background of idiopathic inflammatory myopathies (IIM) such as polymyositis (PM), dermatomyositis (DM) and any overlapping subsets, with other collagen vascular diseases, HLA class I antigens and class II alleles were determined and compared from individuals with various clinical and serological features of IIM, including pulmonary interstitial lesions (PI). Seventy-three Japanese patients with myositis (32 PM, 18 DM, 23 overlapped subsets) and 62 healthy unrelated controls were enrolled onto the study. Statistical differences between groups were determined by the Fisher's exact probability test.

[A case of antiphospholipid antibody syndrome with variable renal histological change despite of poor changes in urinalysis].

We experienced a case of lupus nephritis with antiphospholipid antibody syndrome. A renal biopsy specimen from this patient showed various renal histological changes, but the results of urinalysis were almost normal. The patient was a 56-year-old woman diagnosed as having systemic lupus erythematosus with antiphospholipid antibody syndrome in 1983.

[Two cases of episodic angioedema associated with eosinophilia].

We experienced two cases of limb edema of unknown pathogenesis. No evidence was found concerning involvement of the kidneys, heart of other visceral organs. Case 1 was 22-year-old woman.
