Relapsing polychondritis with crescentic glomerulonephritis.

Relapsing polychondritis is rare and its cause is unknown. The tissues affected are those with a high glycosaminoglycan content, such as cartilage, the aorta, the sclera and cornea, and parts of the ear. Symptoms can usually be controlled with oral steroids, but when there is coexistent progressive crescentic glomerulonephritis quadruple chemotherapy may be used. Three cases of the clinical syndrome of relapsing polychondritis were studied in which rapidly progressive cresentic glomerulonephritis developed. In two the patients appeared to respond to aggressive treatment with immunosuppressive agents and anticoagulants. The multisystemic nature of the disease, the renal lesions, and the response to treatment all suggested that the condition might be related to periarteritis nodosa.

Methylprednisolone pulse therapy in the treatment of polyarteritis nodosa.

Two cases of lung granulomata associated with "crescentic" glomerulonephritis both in a clinical setting of polyarteritis nodosa were treated with high doses of intravenous methylprednisolone ("pulse therapy") in single injections of 30 mg/kg body-weight. In the first case rapidly progressive glomerulonephritis with 100% crescents was arrested and followed by improvement of renal function from a creatinine clearance of 5 ml/min to 30 ml/min; in the second case multiple lung granulomata of 8 months' standing, unresponsive to oral steroids, disappeared 8 days after treatment with high dosage intravenous methylprednisolone. The use of "pulse therapy" with methylprednisolone is advocated, not only in such cases where arteritis is known or suspected, but also in radidly progressive glomerulonephritis associated with crescents.

The different forms of glomerulonephritis morphological and clinical aspects, analyzed in 2500 patients.

Comparative morphological and clinical studies of 2,500 patients suffering from glomerulonephritis, enabled us to divide the different forms of diffuse glomerulonephritis into 3 distinct groups and to separate these groups from the focal glomerulonephritides. The different forms of diffuse glomerulonephritis in group I are: 1. endocapillary (acute) glomeruloenphritis (of the post-streptococcal type), 2. mesangioproliferative glomerulonephritis, 3. mesangioproliferative glomerulonephritis with focal crescents, 4. mesangioproliferative glomerulonephritis with focal scarring, 5. minimal proliferating intercapillary glomerulonephritis without nephrotic syndrome. It is emphasised that these forms can transform into one another, that they seldom occur with nephrotic syndrome, and with varying frequency with hypertension. Group II consists of: 1. minimal proliferating intercapillary glomerulonephritis with nephrotic syndrome, 2. focal sclerosing glomerulonephritis, 3. perimembranous glomerulonephritis, 4. membranoproliferative glomerulonephritis, 5. lobular glomerulonephritis. It is stressed that these glomerulonephritis forms usually do not develop out of group I type glomerulonephritis forms, and that in this group a nephrotic syndrome is the most prominent clinical syndrome. In the third group are 1. mesangioproliferative glomerulonephritis with diffuse crescents, 2. necrotising glomerulonephritis. It is shown that this form of glomerulonephritis does not usually develop from either group I of II forms. The fourth group of focal glomerulonephritis is uncommon. This disease is characterized by a necrotising and proliferative inflammatory lesion found segmentally and focally in the glomeruli. Most of the other glomeruli appearing normal. It is emphasised that in the literature the diagnosis focal glomerulonephritis is made far too often. This is because glomeruli in which the inflammatory process in a few lobules is of varying prominence, are included in the focal glomerulonephritis group. The classification of the different forms of glomerulonephritis into 3 groups here described, is thought of as a basic classification. It is compared with Ellis' classification (1942), with which it has much in common.

[Perimembranous glomerulonephritis after treatment with D-penicillamine. Report on 31 cases (author's transl)].

This report includes 31 patients who developed a perimembranous glomerulonephritis generally 7 months after the onset of the treatment of various illnesses with D-Penicillamine. In all cases the patients had a proteinuria, associated with a hematuria in 12 cases. After the treatment was stopped 8 patients rapidly developed a nephrotic syndrome, while its onset was more gradual in 12 other patients. 5 patients initially with a nephrotic syndrome had no proteinuria at the time of a second biopsy made up to 12 months later. In these 5 cases the typical changes of perimembranous glomerulonephritis observed on electron microscopy were much reduced in the second biopsy.

750 MHz 1H-NMR spectroscopy of human blood plasma.

The application of high-resolution 750 MHz 1H-NMR spectroscopy to a biological fluid is demonstrated for the first time and its advantages over 600 MHz 1H observation shown by reference to studies on human blood plasma. Improvements in signal dispersion were observed which facilitated improved signal assignments. Differences in lipid/lipoprotein signal line-widths between 600 and 750 MHz were noted indicating that ultrahigh field measurements may help to give insight into dynamic motional phenomena of lipids in whole plasma. The two-dimensional J-resolved (JRES) technique and spin-echo spectra measured at 750 MHz have enabled new signal assignments to be made in control plasma. The application of 750 MHz JRES to the clinical chemical problem of the detection of abnormal metabolites associated with chronic renal failure is also demonstrated.
