A case of idiopathic crescentic membranous glomerulonephritis is reported. In addition to the present case, eight cases of this type of glomerulonephritis reported in the literature are reviewed. This is an uncommon form of glomerulonephritis, seen in middle age and in both sexes. Clinical presentation is similar to idiopathic membranous nephropathy. Lupus and antiglomerular-basement membrane nephritis should be excluded by serological tests. Prognosis is grave, resulting in end-stage renal failure (ESRD) within a year in most patients. There is no specific therapy known to alter the course of the disease. In this patient, short courses of high-dose corticosteroids, administered during flares of glomerulonephritis, seemed to improve renal function.

Six children with systemic lupus erythematosus treated over the last 10 years are described. There are 3 boys and 3 girls and their ages at presentation ranged from 9.25 to 15 years; follow-up ranges from 11 months to 12 years. The modalities of treatment, methods of follow-up, and regular assessment of lupus activity are discussed with a brief review of the relevant literature. One patient has progressed to end-stage renal failure and is awaiting renal transplantation. Of the others, 2 have mild renal impairment and 3 have normal renal function. We believe that an aggressive therapeutic approach with meticulous follow-up can improve the outlook in children with this condition.

We assessed renal histological features in 20 children with diffuse proliferative lupus nephritis (DPLN) to determine whether they were useful in predicting clinical outcome. Renal biopsies were analyzed by assigning scores indicating an activity index (AI) and chronicity index (CI). Clinical assessment of renal function at biopsy and outcome were graded according to urinalysis, serum creatinine, need for dialysis and/or transplantation, and/or death from end-stage renal failure. Renal function at biopsy correlated significantly with AI and CI. Serum complement (C3 and C4) correlated significantly with CI but not with AI. The usefulness of the clinical grading system was confirmed in ten patients who underwent repeat biopsies. Of these, four converted from DPLN to mesangial or membranous lupus and showed improvement in their grade, while only one of the six with DPLN on both biopsies improved. After a mean follow-up of 4.0 years, 14 of the 20 patients showed clinical improvement, four were unchanged, and two were worse. CI predicted clinical outcome (P less than 0.01) but AI did not. Histologic scores of AI and CI obtained from renal biopsies showing DPLN may be useful in predicting therapeutic responses and designing prospective clinical trials to determine optimum management of children with DPLN.

Patients with lupus nephritis and severe renal failure progress to end-stage renal disease despite aggressive therapy to suppress immunologic function. Within this group is a small subset presenting with rapid progression of renal failure and requiring dialytic support. We reviewed the clinicopathologic data of four such patients who were able to terminate dialysis after acute renal failure due to lupus nephritis. Three of these patients have remained independent of dialysis up to 4 years, and one patient returned to dialysis 1 month following discontinuation. Although glomerular pathology was variable in the four patients, a lesion common to all at presentation was acute tubular necrosis. It is suggested that tubular necrosis may cause reversible renal failure when part of the nephropathy of disseminated lupus treated with corticosteroids.

Four patients presented with the nephrotic syndrome. The histological appearances on renal biopsy were in three characteristic and in one suggestive of lupus nephritis. These patients did not initially have other clinical features of SLE, but three had a positive ANA and one a raised DNA titre. Remission occurred in two patients, in one spontaneously and in another following corticosteroid therapy, but two developed renal failure. During follow-up all developed elevated DNA binding levels and arthralgia or lymphopenia. The ARA classification criteria for lupus were only fulfilled at this late stage.

Over 20 years 42 of 138 patients with systemic lupus erythematosus "died"--that is, suffered actual death or went into terminal renal failure, or both; data from 41 were available for analysis. In most patients the causes of death were multiple. Twenty seven patients went into terminal renal failure, of whom 25 were offered dialysis treatment. Three regained renal function later, 12 survived on dialysis or with functioning kidney allografts--almost all with inactive lupus--but 13 died after starting dialysis, most within a few weeks or months. The principal causes were active lupus or infection. In those patients with renal failure after rapid deterioration in renal function (n = 14) there were nine deaths, while of 10 patients with a slow evolution into renal failure, only four died. Four patients with impaired and 10 with normal renal function died, again most often from complications of lupus or from infection. Vascular disease was a major cause of death in seven patients, all but two of whom were young; of 15 postmortem examinations, eight showed severe coronary artery atheroma, and three surviving patients required coronary bypass operations. Analysis of the timing of death or entry into renal failure showed that in 12 out of 13 patients who died within two years of onset the lupus was judged to be active, while this was true in only eight out of 19 patients who died later. Six of the seven vascular deaths occurred later than two years from onset, while only nine of 26 renal "deaths" occurred before two years; deaths from infections (n = 13) were distributed equally. Despite this and aggressive treatment of active disease, the principal cause of actual death was uncontrolled lupus.

A clinicopathologic autopsy study of the vascular changes in the kidneys of 100 patients with systemic lupus erythematosus was undertaken. Necrotizing arteritis was found in seven patients, mucinous intimal thickening in nine, onion-skin intimal thickening in two, and renal vein thrombosis in two. Active necrotizing arteritis was present most frequently in the arterioles and interlobular arteries, with healing necrotizing arteritis predominating in the arcuate and interlobar arteries. These events were closely related to the activity of glomerular lesions, and immunologic vascular injury seemed to be the causative factor. Rapidly progressive renal failure and severe hypertension had characterized the clinical courses of the patients. Mucinous intimal thickening, present in the arterioles and interlobular arteries, had been accompanied by accelerated hypertension. Although dialysis or accelerated hypertension may have been causes, other factors, including glucocorticoid therapy, must be considered. In one patient with class II lupus nephritis, renal vein thrombosis was considered the cause of the nephrotic syndrome. These vasculopathies, often detected in patients with lupus at autopsy, seem to alter the clinical course.

The authors report the association of a clinically florid form of lupus with malignant hypertension and renal failure. The renal histology revealed lesions of nephroangiosclerosis, with virtually no signs of lupus proliferative glomerulonephritis. With a follow-up period of 42 months, the renal function has returned to normal, although steroid treatment has been interrupted for 33 months. However, intensive antihypertensive treatment is still required. This unusual case is discussed in the light of previous reports in the literature of the association of disseminated lupus erythematosus and malignant hypertension, which is nevertheless a rare entity.

C1 and C3 activation, measured as C1r-C1s-C1 inactivator C1s-C1r-C1IA complexes in serum and circulating C3d were studied in serial samples from 33 patients with SLE. All patients demonstrated exacerbations during observation periods of 10-30 months and were divided into groups according to principal clincal features (mild SLE, severe extra-renal SLE, and lupus glomerulonephritis). Increased C1 activation was consistently found during exacerbation. C3d in plasma was a feature associated with severe disease flares. Activation of C1, but not of C3, was documented before flare-ups of disease activity, but such predictive information was mostly restricted to patients with extra-renal disease. C2 cleavage in plasma, studied serially in a few patients, appeared to be closely associated with C1 activation. Circulating immune complexes, measured with solid-phase C1q assay, did not always increase before development of clinical manifestations. Remission of symptoms was paralleled by decreasing concentrations of C1r-C1s-C1IA and of, when present, C3d. Similar findings were made for immune complexes but only in severe disease. Persisting C3d was observed in 3 patients, who subsequently developed renal failure. C1q levels were transiently low during flare-ups of lupus glomerulonephritis, but otherwise the concentrations of C1q, C4 and C3 did not show consistent patterns of variation in relation to disease activity.

The influence of lupus nephropathy on pregnancy and reciprocally was retrospectively studied in a series of 131 pregnancies observed from 1962 to 1981 in 45 systemic lupus erythematosis (SLE) women with renal involvement. Renal biopsy showed proliferative lupus glomerulonephritis in 27. The incidence of live births, corrected for induced abortions, was 87% in 89 pregnancies started before, and 89% in 32 started after the clinical onset of SLE; it was only 63% in 10 cases where lupus nephritis developed during gestation. Relapse or exacerbation of disease activity occurred in 15 (47%) of 32 pregnancies antedated by the onset of SLE, with irreversible renal failure in two cases. Clinical exacerbation of SLE was observed in 13 (76%) of 17 cases where SLE was clinically active at the time of conception, and in only 2 of 15 cases where lupus nephritis was in stable clinical remission for at least 5 months prior to conception. Our data suggest that a successful outcome of pregnancy, without SLE exacerbation, may be expected, even in the more severe forms of lupus nephritis, when gestation begins after a sustained, complete clinical remission.
