Two cases of transient neonatal diabetes mellitus associated with anemia, macroglossia and umbilical hernia were studied in relation to the possible etiologies that have been postulated to be responsible for this syndrome. Both patients required insulin therapy for the control of their hyperglycemia but case number two needed to be treated for 14 months before glucose normalization occurred. This patient developed classical insulin dependent diabetes mellitus during our follow-up; the HLA typing showed DR4 allele.

Within four years a 44-year-old man developed a glucagonorma syndrome with insulin dependent diabetes mellitus, weight loss, diarrhea, anemia and a marked superinfected eczema. He developed an organo-cerebral psychosyndrome with cognitive retardation and syncoptic disturbance of consciousness, followed by a tetraspasticity with tetraparesis, micturition difficulties and fecal incontinence. There were a general cerebral atrophy as verified by means of MRT and signs of a demyelinating cerebral disease. The plasma concentration of glucagon was 48 fold elevated to 8,536 ng/l. By means of ultrasonography, CT, ERCP, and angiography a tumorous mass of the corpus and tail of the pancreas, 61 x 32 mm in size, was found with signs of infiltration into the region of the aorta and the splenic vein. Furthermore the liver showed diffuse partially cystic metastases. The diagnosis was certified by fine needle biopsy and histologic examination with Grimelius straining. A thrombosis of the femoral vein was detected by CT. The patient was treated by a debulking resection of the corpus and cauda of the pancreas combined with splenectomy and a drug therapy using octreotide. All paraneoplastic symptoms could be widely reduced. Plasma glucagon concentration decreased from 2,200 ng/l to 600 ng/l. Because of a liver enlargement due to the growth of metastases he was successfully treated with dacarbazine 250 mg/m2 per day during six monthly cycles for five days and interferon-alpha 3 x 3 millions units per week for six months followed by a normalization of the liver volumen.

The association of anemia and hyporeninemic hypoaldosteronism (HRHA) in type 1 diabetes has been described, and erythropoietin deficiency has been proposed as the cause. Subjects with type 1 diabetes with (n = 8) and without HRHA (n = 11) were studied, as were subjects taking angiotensin-converting enzyme inhibitors (ACEIs; n = 10). Renal function and sodium excretion were estimated with a 24-hour urine collection. Values for hemoglobin, hematocrit, serum erythropoietin, and red blood cell volume were determined. HRHA subjects were anemic (hemoglobin, 99 +/- 8 g/L ), and ACEI subjects had lower hemoglobin concentrations (120 +/- 4 g/L) compared with controls (134 +/- 3 g/L; P < 0.001 and P = 0.01, respectively). Also, the red cell mass in patients with HRHA was significantly less than that in controls (14.8 +/- 1.4 v 20.8 +/- 1.1 mL/kg; P = 0.004), indicating that the lower hemoglobin level in HRHA is not attributable to an expansion of extracellular volume. Erythropoietin levels in the HRHA (27% +/- 11% of predicted) and ACEI groups (43% +/- 9% of predicted) were low compared with controls (94% +/- 13% of predicted; P = 0.001 and P = 0.005, respectively). Renal function was greater than the levels at which anemia becomes a clinical feature in all groups, but creatinine clearance was less in the HRHA (63 +/- 12 mL/min/1.73 m2) and ACEI groups (76 +/- 11 mL/min/1.73 m2) compared with controls (123 +/- 9 mL/min/1.73 m2; P < 0.001 and P = 0.004, respectively). The fractional sodium reabsorption was decreased in HRHA (98.7% +/- 0.3%) and ACEI groups (98.7% +/- 0.3%) versus controls (99.4% +/- 0.1%; P = 0.007 and P = 0.01, respectively). Subjects with type 1 diabetes with HRHA had low hemoglobin concentrations that were caused, at least in part, by inappropriately low serum erythropoietin levels.

Diabetic angiopathy is a serious problem in antidiabetic therapy. We wanted to investigate whether treatment with the endothelin(A) receptor antagonist LU 135252 or with the angiotensin-converting enzyme inhibitor trandolapril might prevent angiopathy in long-term type I diabetes mellitus. Six groups of male Wistar rats were investigated: untreated age-matched control rats, healthy controls treated with trandolapril (0.3 mg/kg), healthy controls treated with LU 135252 (100 mg/kg), untreated diabetic rats, and diabetic rats treated with either trandolapril or LU 135252. Rats were rendered diabetic by injection of streptozotozin. Duration of the disease was 6 months. Thereafter, rats were sacrificed, and hearts, kidneys, and a mesenterial loop were removed. Hearts and kidneys were processed histologically; the mesenterial loop was perfused with saline at constant pressure for investigation of microvessels using microvideoangiometry while treated with either 30 mM KCl, 1 microM acetylcholine, or 1 microM sodium nitroprusside. All diabetic rats developed hyperglycemia without differences among these three groups. Diabetic rats exhibited marked anemia, which was significantly antagonized by both treatments. The heart capillaries/muscle fibers ratio was decreased significantly in diabetic animals, which was prevented fully by both treatments. Renal glomerular diameter was increased in diabetic rats. This was significantly antagonized by LU 135252 but not by trandolapril. Deposition of homogeneous eosinophilic material within the glomeruli was nearly completely prevented by LU 135252. The acetylcholine-induced vasodilation in mesenteric microvessels was significantly attenuated in diabetic rats, which was significantly antagonized by both treatments. We conclude that both angiotensin and endothelin seem to contribute to the development of diabetic angiopathy and that, in addition to angiotensin-converting enzyme inhibition, blockade of endothelin(A) receptors may be an interesting new approach to antiangiopathic therapy.

Injectable gallium (Ga) nitrate, approved in the United States for the treatment of hypercalcemia of malignancy, has been known for more than 2 decades to have immunosuppressive properties. At therapeutic doses, it has few adverse effects, although high-dose infusions may result in severe nephrotoxicity, particularly in patients who are not adequately hydrated, and severe anemia. In animal models, Ga has been shown to have efficacy in the treatment of adjuvant arthritis, type 1 diabetes, experimental autoimmune encephalomyelitis, experimental pulmonary inflammation, cardiac allograft rejection, experimental autoimmune uveitis, endotoxic shock, and systemic lupus erythematosus. Clinical trials have demonstrated efficacy in Paget's disease of bone and activity against some malignancies, including epithelial ovarian carcinoma, non-squamous cell carcinoma of the cervix, bladder cancer, and non-Hodgkin's lymphoma. Other clinical trials underway include studies of sarcoidosis and rheumatoid arthritis. Future studies should be conducted not only in other autoimmune diseases, such as multiple sclerosis, but also in graft-versus-host disease, leprosy, and acquired immunodeficiency syndrome (AIDS).

The prevalence of coeliac disease (CD) in the adult population is unknown because silent and latent stages do exist. Type 1 diabetes mellitus may be associated with CD because of common genetic background and/or shared pathogenetic mechanisms. We investigated 74 adults with type 1 diabetes (32+/-11 yr, disease duration 13+/-9 yr), 69 parents of diabetic probands (56+/-10 yr), 59 siblings (30+/-11 yr) and 50 healthy controls (35+/-10 yr) for the presence of circulating islet cell antibodies (ICA), anti-glutamic acid decarboxylase antibodies (GADA65), anti-gliadin immunoglobulins A and G (IgA- and IgG-AGA). All patients with raised AGA, performed also IgA anti-endomysium antibody (EmA) indirect immunofluorescence assay. Samples were positive for ICA in 19 diabetics (26%), 4 parents (6%), 4 siblings (7%), 0 controls (p<0.001); for GADA in 34 diabetics (46%), 4 parents (6%), 1 sibling (2%), 0 controls (p<0.001). Twenty-five diabetic patients (34%), 10 parents (14%), 5 siblings (8%), 3 controls (6%) (p<0.001) had raised IgA-AGA (>4.4 mg/l). Four diabetic patients (5%), 5 parents (7%), 0 siblings (0%), 4 controls (8%) had raised IgG-AGA (>18 mg/l). Both IgA- and IgG-AGA were detected in 1 diabetic and 2 parents. The prevalence of ICA, GADA, and IgA-AGA positivity in Type 1 diabetes patients was significantly higher than in controls (p<0.001). Finally, 50 AGA-positive subjects performed EmA test: only 2 of them resulted EmA-positive, a diabetic patient and a sibling. The patient with Type 1 diabetes had a small-bowel biopsy specimen consistent with CD and, as sole evidence of malabsorption, sideropenic anaemia. EmA-positive sibling also showed severe iron deficiency, yet refused endoscopy. We conclude that: 1) CD cannot be diagnosed on the basis of associated IgA- and IgG-AGA alone. Nevertheless, detection of such antibodies is useful, in combination with EmA, in screening for endoscopic biopsy; 2) too high rate of detection of IgA-AGA in Type 1 diabetic patients in comparison with other groups excludes a false positivity of the test itself, while suggests a pathogenetic association of both immunological disorders, perhaps related to abnormal gammadelta TCR-bearing intraepithelial lymphocytes.

We report the case of a 52-year-old woman with long-term type 1 diabetes mellitus, complicated with proliferative retinopathy, autonomic neuropathy and microalbuminuria and moderate renal failure. A normochromic, normocytic are generative anaemia had been diagnosed for three years. Clinical and biological investigations for the aetiology of anaemia remained normal or negative. Anaemia was associated with a concentration of erythropoietin (EPO) in the normal range, but inappropriately low regarding anaemia. Treatment with recombinant EPO induced a rapid increase in haemoglobin level and improved the patient's quality of life. The role of diabetic neuropathy in the genesis of anaemia, in conjunction with a modest renal impairment is discussed.

In Germany, 36% of all new chronic dialysis patients have diabetic nephropathy. The majority are type 2 diabetics. Early intervention has the greatest effect. Incipient nephropathy can be diagnosed by evidence of microalbuminuria (30-300 mg albumin/g creatinine). Proteinuria on the standard test strip (>300 mg/g) indicates manifest nephropathy followed by progressive renal failure. Important cofactors for progression are hypertension, hyperglycemia, and smoking. Low normal blood pressure levels (<130/80 mmHg without and <125/75 mmHG with proteinuria) based on ACE inhibitors/AT1 blockers are the goal. Combination therapies are frequently necessary. This can often reverse microalbuminuria. Chronic renal failure requires special attention (e.g. bone metabolism, anemia, acidosis). Timely initiation of renal replacement therapy (GFR <15 ml/min) reduces morbidity and mortality. In addition to hemo- and peritoneal dialysis, early kidney and in individual cases of type 1 diabetes combined kidney/pancreas transplantation is appropriate.

Anaemia is a common complication of chronic kidney disease (CKD). It is often more severe and occurs at an earlier stage in patients with diabetic nephropathy than in patients with CKD of other causes. This anaemia results from erythropoietin deficiency, which seems to develop in patients with type 1 diabetes even at relatively "normal" levels of serum creatinine. Early erythropoietin- deficiency anaemia occurs in both type 1 and type 2 diabetes, although the prevalence may be higher in type 1 diabetes. However, numerically most patients with erythropoietin-deficiency anaemia have type 2 diabetes as it is a much more common disease. There is also a greater prevalence in women than men but this is not related to iron stores. In addition, erythropoietin-deficiency anaemia is associated with the presence of autonomic neuropathy in patients with diabetes. Small studies have suggested that recombinant human erythropoietin (rhEPO; epoetin) treatment is effective in correcting erythropoietin-deficiency anaemia in patients with diabetes. Additionally, rhEPO therapy improves quality of life and well-being in these patients. Studies also suggest that treatment with rhEPO to restore a normal haematocrit ameliorates orthostatic hypotension. Given the high cardiovascular risk in patients with diabetic nephropathy, it is important to determine in prospective clinical trials whether early anaemia correction can also improve cardiovascular outcomes.

Coeliac disease (CD) is caused by a complex immunological response provoked by grain protein in susceptible people. The majority of people with CD are symptom-free adults; the remainder are prone to a bewildering variety of signs and symptoms, ranging from infertility to type 1 diabetes. Many patients with undiagnosed CD spend years seeking help for complaints such as chronic tiredness or mild abdominal symptoms. In primary care, an appropriate target group to test for CD is people with anaemia (especially women), chronic tiredness, non-specific abdominal symptoms (including so-called "irritable bowel syndrome"), or a family history of CD. The response to an appropriate gluten-free diet is often life-transforming for symptomatic patients. Positive serological tests for CD require confirmation by duodenal biopsy and, if confirmed, referral to a dietitian and a coeliac society, followed by a life-long gluten-free diet.
