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.

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.

A young woman with recurrent deep venous thromboses and spontaneous abortions was studied. She suffered an ovarian infarction followed by aortic thrombosis and renal failure. Evidence for deficient prostacyclin production was found and she responded to treatment with a prostacyclin infusion. This syndrome is identical with that seen in women with the lupus anticoagulant, but the lupus anticoagulant was not detected and no other cause was identified.

We studied retrospectively the influence of lupus nephropathy on the outcome of pregnancy and of pregnancy on the course of lupus nephritis in 213 pregnancies observed from 1962 to 1985 in a series of 73 patients with systemic lupus erythematosus (SLE). Renal biopsy demonstrated diffuse or focal proliferative glomerular lesions in 48 of 66 patients. The overall incidence of live births was 162 in 213 (76%). Fetal death rate, corrected for induced abortions, was markedly higher when SLE first manifested during or immediately after the index gestation (five of 11, or 45%) than in pregnancies that began prior to clinical onset of SLE (16 of 140, or 11.4%) and in those occurring after onset of SLE (five of 38, or 13.1%). Relapse or an exacerbation of SLE activity occurred in 18 (34%) of 53 pregnancies (in 35 women) which took place after the clinical onset of the disease. Such complications were more frequent (16 of 26 cases, or 61%) in pregnancies in which SLE was clinically active at conception as compared with gestations in which SLE was in clinical remission prior to conception (two of 27 cases, or 7%). There were six instances of severe renal "flare-up," four of which progressed to end-stage renal failure (ESRF) within a few years, including one instance in a patient who was in remission before conception. We conclude that successful outcome of pregnancy without deterioration of maternal renal function may most often be obtained even in previously severe forms of SLE, provided gestation is started in a period of sustained therapeutic remission.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical features in 12 women with a circulating coagulation inhibitor (lupus 'anticoagulant') were studied and correlated with findings in 22 renal biopsies in these patients. Four of 12 women had serological evidence of systemic lupus. Only two of 23 pregnancies in these women were successful. Lesions in all biopsies were remarkably similar. Seven biopsies taken during or soon after pregnancy showed acute fibrinoid lesions. 'Acute' lesions consisted of fibrin thrombi in glomeruli arterioles and arteries and double contours in glomerular capillary walls. Biopsies carried out remote from pregnancy in these seven patients showed persisting double contours in glomeruli together with narrowing of arteries due to recanalizing thrombi and cellular intimal proliferation. All other biopsies showed similar lesions. The lesions were essentially the same as those of thrombotic microangiopathy and those described previously in post-partum renal failure. Renal function was severely impaired in four patients and showed moderate impairment in two patients at the time that acute thrombotic lesions were demonstrated in glomeruli. Renal function in two patients improved during plasma exchange therapy. Because all biopsies showed either acute, healing or healed, thrombotic lesions, it is proposed that these lesions are characteristic of the renal findings in patients with a lupus 'anticoagulant'. In all but two cases the acute lesions were seen during or soon after pregnancy.

Critical conditions had been established in 21 (23.1%) of 91 patients with systemic connective tissue diseases for a 12 year period: renal failure (most often), sepsis, pericarditis with cardiac tamponade, hemorrhagic diathesis, terminal arteritis with gangrene, gastrointestinal perforations with peritonitis, etc. The corticosteroids applied in high doses and predominantly parenterally and the immunosuppressors are the main drugs used in the treatment of these conditions. Plasmapheresis when possible is a useful supplement. The prognosis of the acute critical conditions depends mainly on the affected organ (more favorable in pericarditis with tamponade and unfavorable in renal failure and gastrointestinal perforations with peritonitis (and on the basic disease) more optimistic in systemic lupus erythematodes and very pessimistic in nodal periarteritis and other allergic vasculitis).

We encountered five otherwise healthy adults with alterations of the tarsal navicular bone compatible with spontaneous osteonecrosis. Four women had bilateral involvement and one man had unilateral involvement. The patients were 23-71 years old. The disorder was initially described by Mueller and Weiss and should not be confused with Koehler disease (osteochondrosis of the tarsal navicular in children). This group of patients was compared with five other patients (29-74 years old) with similar radiographic and clinical changes in whom an underlying disease (rheumatoid arthritis, renal failure, trauma, and lupus erythematosus) associated with osteonecrosis was known. Routine radiography in both groups defined characteristic abnormalities of the navicular bone (decreased size, a comma-shaped configuration, increased radiodensity, fragmentation, and medial or medial and dorsal osseous protrusion). MR in three patients confirmed alterations consistent with osteonecrosis. Three of the patients without underlying disease had bilateral involvement on plain films, with flat feet and hindfoot valgus deformity, leading to local pain and deformity. In a fourth patient, bilateral distribution was documented by MR as marrow alterations. Although no certain pathogenic explanation for spontaneous osteonecrosis of the tarsal navicular is known, trauma and chronic stress changes caused by physiologic pressure on the medial longitudinal arch in hindfoot valgus and increased tension forces of the plantar aponeurosis during weight-bearing (in pes planus) may be important. Discrimination of primary from secondary osteonecrosis of the tarsal navicular bone is not possible by radiologic means alone, although bilateral distribution, particularly in women, favors the diagnosis of spontaneous disease.

Predominant interstitial nephritis is a rare manifestation of systemic lupus erythematosus. Only seven cases have been reported in the literature. Owing to the rarity of this entity, the natural history of predominant interstitial nephritis in lupus has not been adequately recorded and an appropriate therapeutic approach has yet to be defined. In this report we present the case of a 25 year old woman with active systemic lupus erythematosus complicated by kidney failure and renal tubular acidosis due to predominant interstitial nephritis. We describe the course of her disease over a three year period. Seven additional patients with systemic lupus erythematosus and predominant interstitial nephritis are reviewed.

We evaluated renal function in 107 patients with active lupus nephritis who participated in long-term randomized therapeutic trials (median follow-up, seven years). For patients taking oral prednisone alone, the probability of renal failure began to increase substantially after five years of observation. Renal function was better preserved in patients who received various cytotoxic-drug therapies, but the difference was statistically significant only for intravenous cyclophosphamide plus low-dose prednisone as compared with high-dose prednisone alone (P = 0.027). The advantage of treatment with intravenous cyclophosphamide over oral prednisone alone was particularly apparent in the high-risk subgroup of patients who had chronic histologic changes on renal biopsy at study entry. Patients treated with intravenous cyclophosphamide have not experienced hemorrhagic cystitis, cancer, or a disproportionate number of major infections. We conclude that, as compared with high-dose oral prednisone alone, treatment of lupus glomerulonephritis with intravenous cyclophosphamide reduces the risk of end-stage renal failure with few serious complications.

Well-documented cases of systemic lupus erythematosus (SLE) with thrombotic microangiopathy (TMA) are rare. Renal biopsy in a 25-year-old woman with SLE who was in renal failure demonstrated proliferative lupus glomerulonephritis with arteriolar thrombosis and the arterial intimal changes of TMA. No staining of vessels for immunoglobulins or complement was found by direct immunofluorescence. Fibrillar and flocculent deposits were seen in the widened and rarefied subendothelial space in a small artery and two glomeruli, one of which also contained electron-dense deposits. The vascular findings, which are those of TMA, are distinct from the immune complex vasculopathy of SLE.
