Hyperlipidemia is common in patients with glomerular proteinuria. It may contribute to atherosclerotic complications and accelerate glomerular damage. Early trials of the fibric acid derivative clofibrate led to a myositis syndrome causing many nephrologists to abandon attempts at treatment of nephrotic hyperlipidemia. Recent trials with lipid-lowering medications have been successful without major side effects. The bile acid sequestrants colestipol and cholestyramine bind bile acids in the gut and deplete the hepatic cholesterol pool, thus inducing LDL hepatocyte receptors. Recent studies showed a reduction of total cholesterol of 8-20% and LDL cholesterol of 19-31% without significant changes in HDL cholesterol. Probucol has reduced total cholesterol 23-30% and LDL cholesterol 23-25% in nephrotic patients. Although HDL cholesterol was reduced, the LDL/HDL ratio remains favorably changed. The fibric acid derivative gemfibrozil inhibits adipose lipolysis and enhances lipoprotein lipase activity thus decreasing LDL synthesis and increasing its removal. It caused a large decrease in triglycerides with a 13-15% decrease in total and LDL cholesterol in a recent trial. HDL cholesterol increased 18%. The HMG-CoA reductase inhibitors inhibit the rate-limiting step in cholesterol biosynthesis hence inducing an increase in LDL receptors on hepatocytes. Trials have shown decreases of 18-36% in total cholesterol and 18-47% in LDL cholesterol, while HDL cholesterol was either increased or unchanged. The use of lipid-lowering agents of several classes has been effective in ameliorating the progression of glomerular damage in a number of different models of glomerulosclerosis. Nevertheless, so far in humans lipid lowering drugs have not been established to have an effect on either the degree of proteinuria or the progression of glomerulosclerosis.

After a controlled, double blind multicenter trial of D-penicillamine in the treatment of rheumatoid arthritis, 148 patients were followed for an additional year in an open label trial. Complications of longterm D-penicillamine included rash, gastrointestinal manifestations, proteinuria, bone marrow depression, myasthenia gravis, myositis, acute febrile reaction and pemphigus foliaceus. With the exception of one patient with myasthenia gravis, all adverse reactions resolved after withdrawal of D-penicillamine. While the complications of D-penicillamine therapy are usually dose related, these reactions can occur at any time and at any dose. Continued and frequent longterm monitoring of D-penicillamine therapy is required.

The protean manifestations of Legionnaires' disease are described in an analysis of 12 sporadic cases. Two forms of the disease have been delineated. One variant (Group A) consisted of six patients who had a mild form of non-progressive pneumonia with minimum extra-pulmonary involvement. Six patients (Group B) were differentiated by rapidly progressive pulmonary infiltrates, severe hypoxia and respiratory failure, plus a higher frequency of band neutrophils and extra-pulmonary manifestations. Particularly notable were evidence of severe myositis (elevated creatinine phosphokinase and lactate dehydrogenase), anaemia, and neurological findings which included alterations in the sensorium, meningitis, and convulsions. Cerebrospinal fluid (CSF) abnormalities were seen frequently in patients with neurological manifestations, and necropsy findings in one patient suggested that the Legionnaires' bacillus was capable of producing a fatal leucoencephalitis. Renal findings included haematuria, proteinuria and oliguric renal failure. Hepatic transaminases (SGPT, SGOT) were elevated in six patients and serum bilirubin was abnormal in five. Alkaline phosphatase values were normal to minimally elevated. The gastrointestinal symptoms commonly considered to be a frequent initial manifestation of Legionnaires' disease were rare in this series. Recommendations for instituting empirical therapy, based upon recognition of a clinical syndrome which should suggest the diagnosis of Legionnaires' disease, are included.

Myositis was diagnosed twenty months after starting treatment with d-penicillamine in a patient suffering from uncomplicated rheumatoid arthritis for nearly three years. The diagnosis was established by electromyographic investigation and by biopsy. In this patient d-penicillamine had been intermittently increased to a dose over 1 g per day and then reduced because of mild proteinuria. The appearance of myositis during d-penicillamine therapy, its immediate regression on discontinuing the drug, and the absence of signs of vasculitis or other extraarticular manifestations in this patient suggest that this complication may be drug-induced. The clinical course is compared with isolated cases reported in the literature. The significance of this rare side effect is discussed.

A 20-year-old man experienced the onset of progressive scleroderma-like skin changes with eosinophilia and hypergammaglobulinaemia after strenuous military activity. A biopsy showed faciitis. Concomitant splenomegaly, polysynovitis, restrictive lung function, myositis, decrease hepatic clotting factors and proteinuria were documented. He responded well to corticosteroids, relapse upon their discontinuation and had a complete remission of both skin and systemic features while on penicillamine and azathioprine. He is new in good health and has received no medication for the past two years.

Induction therapy of promyelocytic leukemia with all-trans retinoic acid is a standard therapy despite significant side-effects. The most important, the "retinoic acid syndrome", consists of a hyperinflammatory reaction with capillary leakage (edema, pleural, and pericardial effusion), infiltration of myeloid cells into internal organs and systemic signs of inflammation. We describe here two cases of another hyperinflammatory reaction during all-trans retinoic acid therapy, the Sweet's syndrome, consisting of infiltrates of the skin and internal organs by neutrophilic granulocytes. Fever, painful erythematous cutaneous plaques, prominent musculoskeletal involvement (myositis, fasciitis), a sterile pulmonary infiltration and intercurrent proteinuria characterized the clinical course of all-trans retinoic acid-associated Sweet's syndrome. Treatment with glucocorticoids led to resolution of the syndrome within 48 h. Three other cases of all-trans retinoic acid-associated Sweet's syndrome without involvement of internal organs, prominent on our cases, were published previously. Recognition of ATRA-associated Sweet's syndrome is of practical importance.

Hantaviruses are etiologic agents of hemorrhagic fever with renal syndrome, an acute illness characterized by acute renal insufficiency, proteinuria, and hemodynamic instability. Recently, a New World form of hantavirus disease, hantavirus pulmonary syndrome (HPS), was recognized; in this form, pulmonary edema is prominent, but renal insufficiency is generally lacking. HPS cases from the southeastern United States may be exceptional in that they have exhibited both pulmonary and renal manifestations. One case in Louisiana and one case in Florida were linked to infection by the distinct but closely related Bayou and Black Creek Canal hantaviruses, respectively. We report a nonfatal case of HPS caused by Bayou hantavirus that occurred in eastern Texas. Clinical manifestations included pulmonary and renal insufficiency and myositis, which had previously been observed in the patient from Florida. The occurrence of distinctive clinical abnormalities in HPS cases from the southeastern United States supports the concept that there are clinically significant differences between western and southeastern forms of HPS.

The objective was to study the relationship between the levels of interleukin-1 receptor antagonist (IL-1Ra) and disease activity and the acute-phase response in SLE patients with and without renal involvement. Twenty SLE patients who had distinct active clinical manifestations (eight glomerulonephritis, four systemic vasculitis without kidney involvement, nine skin rash, 12 arthritis, five serositis, four neuropsychiatric manifestations, three thrombocytopenia, one myositis and one haemolytic anaemia) were studied during a period of 8-12 months. Serum and plasma samples were taken at intervals of 6 weeks-4 months and tested for IL-1Ra, IL-1 beta, IL-6, IgG and anti-dsDNA, Clq, C3, C4 and C-reactive protein (CRP). IL-1Ra serum concentrations were increased in most SLE patients with active disease when compared to normal blood donors. However, at the time of flare, significantly higher levels of IL-1Ra were observed in patients with extra-renal disease as compared to other patients (median [range]: 363 [202-3041] and 4847 [268-27180] pg/ml for patients with and without renal involvement, respectively). This difference was not due to proteinuria. IL-1Ra levels did not correlate with SLEDAI score during flares, but they were elevated during flares in patients with extra-renal manifestations. When disease activity was at its highest, IL-1Ra concentrations correlated with IL-1 beta (r = 0.76; P < 0.001), IL-6 (r = 0.60; P < 0.01) and CRP (r = 0.61; P < 0.01), but not with C1q, C3, C4 and anti-dsDNA levels. The study showed that the pattern of inflammatory cytokines in active SLE varies in a manner that is dependent on which organs are involved. A relative absence of IL-1Ra response appears to be a feature characteristic of kidney involvement. IL-1Ra elevation clearly correlates with flares involving other organs.

A Danish multicentre study was undertaken of the manifestations, infections, thrombotic events, survival and predictive factors of survival in 513 Danish patients with systemic lupus erythematosus (SLE) according to the 1982 classification criteria of the American College of Rheumatology. The mean duration of follow-up was 8.2 years from diagnosis and 12.8 years from first symptom. This paper describes the most common clinical and laboratory manifestations and their relationship to sex and age at the time of onset and diagnosis. Cluster analysis revealed three clinically defined clusters at the time of disease onset. Cluster 1 (57% of patients) consisted of relatively elderly patients without nephropathy or malar rash, but with a high prevalence of discoid lesions. Cluster 2 (18%) consisted of patients with nephropathy, a third of whom also developed serositis and lymphopenia. The patients of the third cluster (25%) all had malar rash and half were photosensitive. Follow-up showed that the patients of cluster 2 developed azotaemia, large proteinuria, arterial hypertension and myositis significantly more often than did the rest of the patients, but the mortality was not increased. The risk of developing renal end-stage disease was highest in men with early-onset disease.

The medical records of 158 dogs with visceral leishmaniasis confirmed cytologically and/or serologically were reviewed. Ages of affected dogs varied from nine months to 15 years, with a male-to-female ratio of 1.3. The most common clinical manifestations of the disease were variable cutaneous lesions such as exfoliative dermatitis and skin ulcerations, chronic renal failure, peripheral lymphadenopathy or lymph node hypoplasia, masticatory muscle atrophy (i.e., chronic myositis), ocular lesions (i.e., conjunctivitis, keratoconjunctivitis sicca, blepharitis, and uveitis), and poor body condition. Ascites, nephrotic syndrome, epistaxis, polyarthritis, and ulcerative stomatitis were seen only in a small number of cases. Clinical splenomegaly was not a common finding. The clinicopathological abnormalities were nonregenerative anemia, hyperproteinemia, glomerular proteinuria, and symptomatic or asymptomatic azotemia. In this study, an indirect immunofluorescence assay's diagnostic sensitivity was found to be higher than that of lymph node aspiration cytology.
