Sixteen patients suffering from rheumatoid arthritis (RA) (n = 8), systemic lupus erythematosus (SLE) (n = 5), and systemic sclerosis (SSc) (n = 3), and 10 healthy subjects matched for age, sex, and body mass index, were submitted to an intravenous (IV) glucose tolerance test (GTT) (0.33 g/kg of body weight in 3 minutes) and to a euglycemic hyperinsulinemic glucose clamp to study insulin response and action. In the euglycemic clamp, along with the two insulin infusion rates (0.5 mU/kg.min from 0 to 120 minutes and 1 mU/kg.min from 121 to 240 minutes), a primed (20 microCi) continuous (0.2 microCi/min) infusion of 3H-glucose allowed determination of glucose kinetics. Our data show that patients versus controls have (1) a significant increase in basal plasma insulin levels (87.2 +/- 14.8 v 41.3 +/- 6.0 pmol/L, P less than .05); (2) similar glucose-induced acute insulin response; and (3) a lower glucose disappearance rate (Rd), glucose metabolic clearance rate (gMCR), and glucose infusion rate (GIR) when the lowest insulin infusion rate was delivered. These differences disappeared when the insulin infusion rate was doubled. Furthermore, basal plasma insulin levels and glucose disappearance rate significantly correlated with the main inflammatory indices of each disease studied. We conclude that in our patients impaired glucose handling is mainly due to peripheral insulin resistance.

We describe a patient with systemic lupus erythematosus (SLE) who presented with acute transverse myelitis. Magnetic resonance imaging (MRI) of the cervical spine demonstrated increased signal intensity and diffuse edema in the cervical cord. The patient had low titer of IgG antiphospholipid antibodies and hypocomplementemia. Cerebrospinal fluid analysis showed pleocytosis, increased protein and decreased glucose. Clinical improvement of the neurologic impairment was noted after high dose corticosteroids and intravenous bolus cyclophosphamide. A repeat MRI 12 days after the treatment was normal. MRI of the spine can be useful in the diagnosis and followup of patients with SLE presenting with an acute myelopathic syndrome. Early aggressive treatment may contribute to complete recovery of these patients.

An elderly woman with unexplained episodic fasting hypoglycemia was hospitalized for ascites. Evaluation revealed polyserositis, arthritis and immunologic abnormalities that suggested the diagnosis of systemic lupus erythematosus (SLE). Antibodies to insulin receptor with insulin binding inhibitory activity were detected in her serum. Treatment with prednisone was accompanied by resolution of hypoglycemic episodes and disappearance of the antireceptor antibodies. Autoantibody mediated alterations in serum glucose may be included in the growing list of autoimmune phenomena in SLE. Antiinsulin receptor antibodies should be sought in patients with SLE and idiopathic hypoglycemia.

A 47-year-old man with Graves' disease suffered from a feeling of hunger and sweating in the night, polyarthralgia and fever one month after the start of treatment with methimazole. The above symptoms were ascribed to the side effects of methimazole; insulin autoimmune syndrome and lupus-like syndrome. The change in the antithyroid drug to propylthiouracil caused an amelioration of the symptoms. In addition to an anti-insulin antibody with a high binding capacity, hyperglucagonemia (260 pg/ml with a plasma glucose level of 61 mg/dl) was observed, which returned to normal in parallel with the decrease in the insulin binding capacity of the plasma one month after beginning the treatment with propylthiouracil. A normal decrease in the plasma glucagon level due to exogenous insulin (2 mU/kg/min) was observed with the euglycemic clamp. However, the plasma glucagon level was not suppressed by the oral glucose loading and elicited a poor response to the arginine infusion. Taking previous reports into account, this basal hyperglucagonemia seems to be a characteristic finding in the insulin autoimmune syndrome, while a sluggish response of glucagon to oral glucose or arginine infusion might be ascribed to hyperthyroidism. This is the first case report concerning a kinetical study of the glucagon secretion in insulin autoimmune syndrome with Graves' disease.

During a survey period of 28 years a total of 449 patients suffering respectively from pemphigus, systemic lupus erythematous and chronic nephritis was admitted to the hospital. Of the 286 patients who received glucocorticoid treatment 28 were found to have steroid diabetes (9.8%). The incidences of steroid diabetes in these diseases were as follows: pemphigus 20% (7/35), systemic lupus erythematous 12.5% (14/112), chronic nephritis 5% (7/139). Two thirds of the diabetic subjects appeared asymptomatic, while the remainder showed polydipsia and polyuria. Renal glucosuria was seen in 3 cases and hyperosmolar hyperglycemia in 4. Blood glucose level in 10 out of the 21 remaining cases was 8.9 +/- 1.5 mmol/L and in the other 11 cases 14.8 +/- 2.4 mmol/L. Generally, the treatment of steroid diabetes is not intricate. Satisfactory improvement was seen in about 80% of the patients if a strict line of therapy against primary diabetes was oriented. In this series 18 patients did well under the treatment either with reduction of steroid or with use of oral hypoglycemic agents or insulin or both. Their blood glucose levels returned to normal and urine sugar disappeared rapidly. Four of the 5 deaths were caused by their primary diseases. One died of pemphigus complicated with infection and shock exhibiting an ante mortem blood glucose level as high as 31.7 mmol/L, obviously hyperosmolar status being the predisposing factor. Due to the fact that most of the steroid diabetic patients were clinically asymptomatic, delayed or misbranded diagnosis was not infrequently seen.(ABSTRACT TRUNCATED AT 250 WORDS)

The beneficial effects obtained with dehydroisoandrosterone (DHA) feeding in the treatment of murine systemic lupus erythematosus are similar to those obtained with caloric restriction or with dietary manipulation of essential fatty acid availability. In this study, the fatty acid composition of selected tissues was examined in NZB/W F1 mice fed a diet containing 0.4% DHA. The effect of the DHA diet on liver composition and the activity of key hepatic enzymes involved in fatty acid synthesis and glucose metabolism was also investigated. The content of the essential fatty acid, arachidonate, was decreased in plasma cholesteryl esters and liver and kidney phospholipids in mice fed the DHA diet, yet no significant decrease in arachidonate content was observed in plasma phospholipid. The most striking change in both plasma and liver phospholipid was an increase in palmitic acid and a decrease in stearic acid, which could result from a decreased ability for fatty acid elongation. The liver mass was dramatically increased in the mice fed DHA, primarily from parenchymal cell hypertrophy, and contained little lipid. Significant changes in the activities of malic enzyme, glucose-6-phosphate dehydrogenase and pyruvate kinase, similar to those changes which occur with fasting, were observed during the initial adaptation to the DHA diet. The pyruvate kinase activity remained low, suggesting a decrease in liver glycolysis. These results are consistent with the concept that diets containing DHA result in an altered metabolism with a decreased dependence on carbohydrate metabolism and an increased metabolism of lipids.

Peripheral blood adherent cells from patients with systemic lupus erythematosus (SLE) were shown to have markedly reduced phagocytic activity as compared to normal adherent cells or those from non-SLE patients receiving corticosteroid therapy. Both resting and phagocytosing monocytes showed decreased hexose monophosphate shunt and glycolytic activity. Mononuclear cells from SLE patients showed grossly impaired proliferative activity after NaIO4 activation. Furthermore, addition of SLE adherent cells to normal adherent cell-depleted lymphocytes decreased [3H]thymidine incorporation of the latter cells following NaIO4 treatment. Addition of normal adherent cells to SLE lymphocytes corrected the previous defect, indicating that an adherent abnormality is responsible for the defect in SLE mononuclear cell proliferation to NaIO4 activation.

The pathophysiology of chorea in systemic lupus erythematosus (SLE) is uncertain. Pathologic examination has not identified a specific location for the causative lesion(s) and immunologic mechanisms have been suggested in its etiology. In other choreic disorders, such as Huntington's disease and benign hereditary chorea, glucose hypometabolism in the striatum has been demonstrated by positron computed tomography (PCT) using [18F]deoxyglucose. With this technique we have studied four patients with chorea secondary to SLE. In these patients the regional distribution of cerebral glucose metabolism was normal. In particular, striatal glucose metabolism was within the normal range, even though the ratio of striatal to cortical glucose metabolism was increased. Our results show that striatal hypometabolism, as seen in other disorders manifesting chorea, is not the PCT correlate of the dyskinesia.

Autoantibodies in sera from newly diagnosed insulin-dependent diabetes mellitus (IDDM) patients recognize a 64,000 Mr human islet cell antigen. The incidence of these antibodies was 86% in 28 insulin-dependent diabetes mellitus patients, 100% in seven first-degree relatives with abnormal glucose tolerance, 6% in 34 healthy individuals, 17% in 29 patients with Hashimoto's or Graves' disease, and 0% in five systemic lupus erythematosis patients. It is suggested that the 64,000 Mr human islet cell protein is the major target antigen of islet cell autoantibodies in insulin-dependent diabetes mellitus.

In the studies reported here we demonstrate that bombesin decreases food intake in wolf (Canis lupus) pups without altering glucose or insulin levels. A high dose of cholecystokinin-octapeptide (CCK, 5 micrograms/kg) decreased food intake. CCK produced a transient increase in insulin, without altering glucose. Glucagon (0.5 mg/kg) failed to decrease food intake despite producing a marked hyperglycemia and hyperinsulinemia. Calcitonin was ineffective at decreasing food intake, although it did decrease the time spent feeding. These studies suggest a potential role for peripheral peptides in food regulation in the wolf.
