The prognostic markers in 87 consecutive patients with lupus nephritis who underwent renal biopsy are reported for five clinically relevant long-term outcomes--renal insufficiency, renal failure, death due to renal systemic lupus erythematosus, death due to non-renal SLE and death due to SLE, both renal and non-renal. We have demonstrated that a number of previously neglected or rarely studied predictors were important prognostic markers. These included the duration of renal disease before biopsy, overall severity of SLE, as well as the presence of vasculitis, hypertension or a comorbid ailment. Furthermore, the study confirms the predictive importance of serum creatinine, 24-h urinary excretion of protein, C3, and of the activity and chronicity indices on biopsy. However, overall a simple measure of tubulointerstitial disease was the best predictor obtained from biopsy. Prognostic models based on clinical data alone were developed for each of the five outcomes. The models amplify our clinical understanding of lupus nephritis. Markers of renal severity were most important in predicting renal outcomes such as renal insufficiency and renal failure. Prognostic factors less directly related to renal disease (comorbidity and vasculitis) were important predictors of fatality. A marker of immunologic disease activity (C3) was a valuable predictor for many of the outcomes. Thus markers of disease severity reflecting organ damage due to SLE and other comorbid conditions could be combined with markers of immunologic activity to predict a variety of outcomes of relevance to a clinician. When biopsy data obtained by light or electron microscopy were evaluated for their ability to add new predictive information to the clinical models, only a limited value for biopsy was noted. It is likely that this reflected the close correlational relationships between clinical and biopsy variables, the strong clinical models generated, and the inclusion in the clinical models of the previously neglected clinical variables, duration of renal disease before biopsy and the presence of vasculitis or comorbid disease.

A total of 411 children, aged from 0.3 to 18 years, suffering from glomerular diseases, were studied by renal biopsy between 1976 and 1985. The clinical presentation included nephrotic syndrome (79% of cases), renal failure (43%), and arterial hypertension (38%). In all, 177 cases presented with primary nephrotic syndrome; all had complicated courses and most were either corticosteroid-dependent or -resistant. Only 26.6% had minimal change disease on renal biopsy; 56.5% had focal-segmental sclerosis; and immunofluorescent deposits were observed in half of the group. Acute poststreptococcal (36 cases), mesangiocapillary (80 cases), and lupus (34 cases) glomerulonephritis occurred frequently; IgA glomerulopathy (10 cases) and haemolytic uraemic syndrome (6 cases) were uncommon. Glomerular crescents were observed in 71 cases. These observations illustrate the types of glomerular diseases seen in Iranian children.

A retrospective study of all patients with systemic lupus erythematosus (SLE) who died at the University Hospital of the West Indies over a 14-year period is presented. The major cause of death was infection followed by renal failure. Gram-negative organisms were the major microbiological agents causing infections. Side-effects of therapy were common, in particular bone marrow depression and haemorrhage related to anticoagulants. It appears that controlling severe lupus activity without increasing the risk of lifethreatening complications remains an important goal in the treatment of SLE.

In 177 patients with lupus nephritis in the course of three decades three methods of immunotherapy were used the effect of which was evaluated retrospectively. When the criterium of the survival period was used, it was revealed that from a group of 66 patients treated only with glucocorticoids (mainly prednisone by the oral route) less than 60% survived five years the onset of lupus nephritis, only 33% survived 10 years. From a group of 81 patients treated with glucocorticoids and cytostatics (mostly cyclophosphamide by the oral route) 80% survived five years and 50% ten years, while in a group of 30 patients treated with glucocorticoids, cyclophosphamide and levamisole 90% survive five years and as many as 70% ten years from the onset of lupus nephritis. From the onset of SLE however as many as 80% survived ten years in all three analyzed groups, which provides evidence that lupus nephritis accounts for the greatest mortality in patients with SLE, as renal failure was the cause of death in one third of the patients. As to complications, secondary infections were recorded in almost 30% of the patients, incl. 9% lethal ones, non-infections complications less than 5%. The authors discuss assumed mechanism of the action of combined immunotherapy, which holds a priority position, as compared with glucocorticoid monotherapy.

We report a case of an 8-year-old girl with adrenogenital syndrome secondary to adrenocortical hyperplasia. Thirteen years later systemic lupus erythematosus developed with lupus nephritis. In spite of complex continuous immunosuppressive therapy, she died from terminal renal failure. At autopsy, extensive bilateral renal malacoplakia was discovered. The role of recurrent urinary tract infections and of immunological disturbances in the pathogenesis of malacoplakia is discussed.

The possible infections of 43 hospitalized patients with systemic lupus erythematosus (SLE) has been assessed. Out of the 43 patients 17 had some type of infection (41%). The diagnosis was proven by positive cultures in 84% of the cases. Urinary infections due to E. coli were the infections most commonly found. Four infections due to staphylococcus, 2 to S. typhi and 2 to invasive Aspergillosis were also found. Tuberculosis was observed only in 2 patients. In twelve out of the 17 patients with infections, SLE was active and 10 of the latter had renal failure. In addition to the 18 urinary infections diagnosed, sepsis was encountered in 5 patients and pneumonias in 4. Only two infected patients died (those with invasive aspergillosis). Thus, infections are frequent in patients with SLE and precise diagnosis often requires positive culture test.

The authors studied 35 marrow biopsies from 32 patients with rheumatoid arthritis, systemic lupus erythematosus, mixed connective tissue disease, polymyositis, and psoriatic arthritis. Reasons for biopsy included cytopenia, fever of unknown origin, and malignancy. Cellularity was abnormal in 71%. Plasma cells were increased in 60% and associated with lymphoid aggregates. Immunoperoxidase stains showed polyclonal perivascular plasma cells and increased T-cells forming lymphoid aggregates. Two patients had granulomas without documented infection. Anemic patients had findings consistent with anemia of chronic disease, erythroid aplasia, hemolysis, and iron deficiency. Iron stores were variable. Platelet and granulocyte precursors were variably altered and did not predictably correlate with the presence, absence, or cause of thrombocytopenia and neutropenia. Myelodysplastic syndromes were present in two patients with rheumatoid arthritis. Osteomalacia and osteoporosis were seen, resulting from renal failure and steroids. Marrow findings are unpredictable and reflect the diverse causes of cytopenias in patients with connective tissue disorders.

A prospective study of 110 patients with systemic lupus erythematosus (SLE) was undertaken to evaluate the reliability of clinical signs of lupus nephritis, which developed in 39 (35%) patients. Those patients with SLE who showed no clinical signs of lupus nephritis had an excellent survival rate (10 year survival 93%) and retained normal renal function (serum creatinine less than 130 mumols/l); clinical lupus nephritis developed mainly in the first three years after diagnosis of SLE and was associated with a decreased survival rate (10 year survival 62%). Increased mortality was found in male patients with lupus nephritis over 25 years of age and in female patients with lupus nephritis under 25 years of age, while renal failure rates did not differ between these groups. Treatment of lupus nephritis with high dose prednisone alone or in combination with immunosuppressants did not result in differences in patient survival or renal function preservation. It was concluded that clinical variables are a reliable guide in the management of patients with SLE, and routine use of renal biopsy in these patients is rejected.

Clinical and laboratory features were evaluated in 48 patients with lupus anticoagulants and the efficiency of three different assays in the detection of lupus anticoagulants was compared. The diagnosis of lupus anticoagulants was based on a prolonged activated partial thromboplastin test not corrected in a mixture of 1:1 with normal plasma and lack of specific inhibitors against coagulation factors. Platelet neutralization procedure was positive for lupus anticoagulants in 98% of the patients, tissue thromboplastin inhibition ratio in 79%, and kaolin clotting time index in 77%. At least one of the assays was positive in 100% of the cases. The largest minority of the patients (31%) suffered from systemic lupus erythematosus. The others had a variety of non-immunological disorders. In the 13 patients who had been operated on, only 1 with renal failure developed hemorrhagic complications after renal biopsy due to thrombocytopathy. The incidence of recurrent spontaneous miscarriage, immune thrombocytopenia and positive direct antiglobulin test, anti-nuclear and anti-DNA antibodies and VDRL was significantly higher in patients with lupus anticoagulants and systemic lupus erythematosus compared to patients with lupus anticoagulants but without systemic lupus erythematosus.

The diagnosis of recurrent renal disease after transplantation is dependent on an accurate and complete diagnosis of the initial cause of renal failure and a similar determination of the cause of graft failure. To be classified as recurrent, the disease in the renal graft must be identical to that seen in the native kidneys. Recurrence of disease accounts for less than 2% of all graft failures, but the overall incidence of recurrent disease is probably 5 to 10 times more common. The most frequent cause of recurrent disease is glomerulonephritis, which was first recognized to recur soon after renal transplantation was introduced. It was then recognized that a variety of metabolic disorders would recur, but it has taken 25 years of experience for a clear picture to emerge of recurrence in most conditions. No initial cause of renal failure poses a contraindication to at least one attempt at transplantation, although with Fabry's disease and oxalosis, a special assessment of the risks for the individual recipient is warranted. In some patients, experience has shown the need for a delay in the commitment to transplantation (eg, in those with anti-glomerular basement membrane [GBM] antibody glomerulonephritis or Henoch Schonlein purpura), the need for the choice of a particular immunosuppressive regimen (eg, in hemolytic uremic syndrome [HUS]), the need for avoidance of primary nonfunction (eg, in oxalosis), and the desirability of avoiding live kidney donation (eg, in heterozygote donors in Fabry's disease, high-risk recipients with focal glomerulosclerosis, and in recipients with HUS). Probably all types of glomerulonephritis recur, but with great variation in frequency and severity. In some forms of glomerulonephritis, recurrence may be frequent and definite on histopathological criteria but may only have a minor clinical expression (eg, dense deposit disease, anti-GBM antibody glomerulonephritis, IgA nephropathy), but in others, recurrence is less predictable yet it is clearly associated with premature graft failure (eg, focal glomerulosclerosis, membranous nephropathy). A common theme emerging is that where the initial glomerulonephritis is aggressive and causes kidney failure over a short time, recurrence is more likely, and when present, it will lead to graft failure with an increased frequency. Clinical manifestations, the frequency of recurrence, and the prognosis of the graft are now identified for most conditions. Unexpected observations have included the rarity of recurrent systemic lupus erythematosus (SLE), the immediate return of heavy proteinuria in focal glomerulosclerosis, and the predictable return of dense deposit disease.(ABSTRACT TRUNCATED AT 400 WORDS)
