A variety of antihypertensive drugs have been introduced into clinical practice at excessively high dose. Examples include most thiazide diuretics, propranolol, oxprenolol, atenolol, methyldopa, hydralazine and captopril. These very high doses have usually resulted from studies in which doses have been increased at regular intervals until the desired antihypertensive effect has been achieved or until unacceptable adverse effects have resulted. Frequently the starting doses were too high and the intervals between dose adjustment too short. In many cases these large doses resulted in unnecessary adverse effects--the adverse biochemical effects of thiazide diuretics, nephrotic syndrome, taste disturbances and neutropenia with captopril, the lupus syndrome with hydralazine and the central nervous system effects of methyldopa. Parallel group design with single doses and sufficient statistical power to distinguish between the upper and lower ends of the antihypertensive dose-response relationship should replace the dose-escalating design.

C1q deposits are usually found in association with other complement components and immunoglobulins in proliferative glomerulonephritis and may predominate in systemic lupus erythematosus (SLE). We report the clinical outcome of four patients who developed a nephrotic syndrome associated with C1q nephropathy unrelated to SLE. On presentation the mean urinary protein loss was 6.8 g/24 h (range 4-10), and renal function impaired, mean serum creatinine 201 mumol/l (150-400). Over a mean follow up period of 6.5 years (1.7-19), all four patients improved, three spontaneously and one treated with steroids and cyclosporin, to a current urinary protein loss of 0.3 g/24 h (less than 0.2-0.9) and serum creatinine 98 mumol/l (68-115). C1q nephropathy was confirmed in each biopsy by conventional immunohistology. C1q deposits were demonstrated within the glomerular basement membrane of three biopsies and the mesangium in two samples. One patient had been categorized on light- and electron-microscopy as having mesangiocapillary glomerulonephritis, one membranous glomerulonephritis, one proliferative glomerulonephritis with focal segmental glomerulosclerosis, and one diffuse proliferative glomerulonephritis with both subendothelial and mesangial dense deposits. In view of the expected progressive nature of the underlying renal histopathological appearance, the presence of predominant C1q deposits would appear to be associated with a better clinical outcome.

Acquired hypercoagulable states comprise a diverse group of clinical conditions that are associated with an increased risk of thrombosis. These clinical conditions include malignancy, diabetes mellitus, venous stasis, pregnancy, oral contraceptive use, lupus anticoagulant, postoperative state, immobilization, myeloproliferative disorders, and nephrotic syndrome. Recognition of these associations, possible underlying mechanisms, identification of high risk individuals, thromboembolic prophylaxis, and other clinical implications are discussed.

We investigated the clinical significance of glucocorticoid receptor determination in 20 patients with systemic lupus erythematosus (SLE) who afterwards developed nephrotic syndrome. Glucocorticoid receptor concentrations in mononuclear leukocytes (MNL) in these patients were comparable with those in both other patients with SLE and healthy persons. Improvement in urinary protein excretion and in disease activity, which was scored according to the SLE Disease Activity Index system of the University of Toronto, closely related to the glucocorticoid receptor concentrations in MNL isolated from the corresponding patients. In summary, glucocorticoid receptor determination in patients with lupus nephritis may be a predictive clue for assessing responsiveness to glucocorticoid therapy.

In this report the association of autoimmunity and autoimmune syndromes with lymphoproliferative disorders (LPD) is described in 15 patients. Non-Hodgkin's lymphoma (NHL) developed in 10 patients, Hodgkin's disease (HD) in 3 and chronic lymphocytic leukemia (CLL) in two. In most instances clinical and laboratory phenomena preceded the development/diagnosis of these disorders. Manifestations ranged from the presence of autoantibodies in the serum to the presence of both ill defined or incomplete autoimmune syndromes including cold urticaria, Raynaud's phenomenon, cold agglutinin disease, thyroiditis, nephrotic syndrome and vasculitis to typical systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and even one of scleroderma. It is suggested that in some patients (in)complete clinical manifestations of autoimmunity may precede the development of lymphoid neoplasias. The link between autoimmunity and lymphoproliferative disorders is briefly discussed.

Farr's assay using double-stranded (ds) DNA from E. coli is a most sensitive and specific method for the detection of anti ds-DNA antibodies in patients with systemic lupus erythematosus (SLE). Because of the lack of sufficient DNA antigens, however, final antibody titers were hardly determined when the sera contained antibodies titered more than 100U/ml (or more than 60 per cent by DNA binding activities). In such sera DNA binding activities were measured by using ds-DNA tracer adjusted final concentration of NaCl to 125 mM. Higher binding activities measured by high-salt tracer are obtained significantly in SLE patients groups with nephrotic syndrome, proteinuria, cast, renal failure, diffuse proliferative nephritis, low serum complement levels, anemia and/or low IgG/IgA levels compared with the patients who lacked these clinical findings. In contrast the patients with digital rash or cramp showed significantly lower high-salt binding activities. The patients with pleuropericarditis tended to have lower bindings. The non-lupus patients including MCTD also had lower levels. These clinical characteristics could not be evaluated by standard Farr's assay. High-salt bindings suggest the presence of high avidity antibodies and also partly may mean the high levels of low avidity antibodies. The application of high-salt binding activities, thus, is a useful tool for the evaluation of clinical characteristics of SLE patients who had high levels of anti ds-DNA antibodies by standard Farr's assay.

The nephrotic syndrome is characterized by proteinuria, hypoalbuminemia and hypercholesterolemia. Hypercholesterolemia is in some cases a risk factor for atherosclerosis in this group of patients. The lipid plasma spectrum was studied in 45 patients with the nephrotic syndrome. Most pronounced changes of the lipid composition of the plasma were revealed in patients with systemic lupus erythematosus and a special form of mesangio-proliferative glomerulonephritis which is characterized by a torpid course and rapid development of chronic renal failure. Plasma atherogenicity was calculated according to the index of plasma atherogenicity. A high atherogenicity index was revealed in patients with an association of the nephrotic syndrome and arterial hypertension. Plasma atherogenicity is determined mainly by the level of high-density-lipoprotein cholesterol.

The overall incidence per year of deep vein thrombosis is about one per thousand, but may be much higher in the presence of certain clinical risk factors such as advanced age, immobilization, surgical procedures, pregnancy, puerperium, use of oral contraceptive agents and malignancy. Moreover, homocystinuria, nephrotic syndrome, systemic lupus erythematosus and hematological disorders such as paroxysmal nocturnal hemoglobinuria or myeloproliferative syndromes predispose to thrombotic disease. Evaluation of the patient with thromboembolism should include detailed history, clinical examination and laboratory investigation to exclude these secondary thrombophilic states. Primary or hereditary thrombophilia is suspected mainly in patients suffering from (venous) thromboembolism at an early age (< 45 years), especially if recurrent and/or familial thrombosis is present. Hereditary thrombophilia may be due to deficiency of antithrombin III, protein C, protein S or plasminogen, some other defects being less well-established prethrombotic risk factors. These currently recognized primary prethrombotic molecular defects are found in 10 to 30% of patients with idiopathic thromboembolism. In the majority of cases the cause of thrombosis remains unknown.

A middle-aged women with hypothyroidism, idiopathic portal hypertension and nephrotic syndrome is presented. This unusual clinical appearance could not be explained as SLE by serological examinations. Pathohistological examinations showed "Banti's liver", Hashimoto's thyroiditis and diffuse proliferative glomerulonephritis with severe tubulo-interstitial nephritis. Immunohistochemical studies revealed IgA deposits in glomeruli. Electron microscopic study disclosed peculiar lucent areas of rarefaction with osmiophilic particles in tubular basement membranes. This tubulointerstitial nephritis was considered to be related to the immunological mechanism involving thyroid gland, liver and kidney disorders. This case thus had a clinically rare combination of these three.

A 36-year-old woman was admitted to the hospital with the diagnosis of nephrotic syndrome due to lupus nephritis. The patient had panperitonitis caused by Staphylococcus aureus as a complication, and an emergency laparotomy was performed. After the operation, the patient developed a massive lung alveolar hemorrhage. Methylprednisolone pulse therapy showed a marked effect on the lung hemorrhage. It is known that lung alveolar hemorrhages associated with systemic lupus erythematosus have a very high mortality; the present case is relatively rare because of the good response to steroid pulse therapy.
