1/219. Effects of diabetes mellitus on patients with acute intermittent porphyria.OBJECTIVES: To study the effects of diabetes mellitus in patients with acute intermittent porphyria (AIP). Haeme deficiency in the liver of AIP patients stimulates an increase in ALA-synthase which triggers an escalating metabolic chain reaction, leading to an increase in the porphyrin content. This reaction can be reduced by treating AIP patients with haeme arginate or with glucose. DESIGN: A population-based study of all patients > 18 years of age having dna-verified AIP (n = 328) living in the two most northerly counties of sweden (Norrbotten and Vasterbotten, with 550,000 inhabitants) of whom 16 had type 2 diabetes. prevalence of diabetes was studied retrospectively in 26 AIP patients with hepatocellular carcinoma (HCC). RESULTS: None of the patients showed symptoms of AIP after the onset of their diabetes. Three patients had had recurrent, severe attacks for many years but when their diabetes became manifest, their urinary ALA and PBG levels decreased and the AIP symptoms resolved, to the relief of the patients. Amongst the 26 AIP patients with HCC, only one with signs of diabetes was identified (impaired glucose tolerance test). CONCLUSIONS: This study raises the possibility that diabetes mellitus may be beneficial for patients with severe AIP.- - - - - - - - - - ranking = 1keywords = glucose (Clic here for more details about this article) |
2/219. Systematic approach to the management of the Type II diabetic patient: case presentation.Recently there has been a trend toward more aggressive management of people with diabetes. This stems from the conclusive clinical data that substantiate the benefit of tight glycemic control. It is clear that achieving near normoglycemia in people with diabetes will prevent and slow the progression of the microvascular complications and reduce the risk of the macrovascular complications. Clinicians now have multiple agents with differing mechanisms and sites of action allowing them to individualize the medication regimen and move toward normalizing the blood glucose levels. The following case is representative of a typical patient with Type II diabetes. This patient presents with multiple disease states and various treatment issues that must be addressed. An in-depth evaluation of the patient case is presented along with recommendations for drug therapy modifications.- - - - - - - - - - ranking = 0.5keywords = glucose (Clic here for more details about this article) |
3/219. Non-insulin-dependent diabetes mellitus with type I multiple symmetrical lipomatosis: a case report.Type I multiple symmetrical lipomatosis (MSL; Madelung's disease) is characterized by lipomas in the nape of the neck and the supraclavicular and deltoid regions, resulting in a bull-necked appearance (Madelung's collar). It is most common in alcoholic men between 35 and 50 years of age. Type I MSL has been reportedly associated with hyperinsulinemia, but its association with diabetes mellitus is rarely discussed. We describe a case of non-insulin-dependent diabetes mellitus (NIDDM) associated with type I MSL. A 47-year-old alcoholic man presented with a seven-year history of hyperglycemia and progressive neck swelling with dysphagia for one year. physical examination showed diffuse and symmetrical swelling of the bilateral posterior aspects of the neck. biochemistry profiles revealed elevated concentrations of fasting serum glucose (276 /- 16 mg/dl), triglycerides (358 /- 79 mg/dl) and total cholesterol (323 /- 28 mg/dl). Endocrinologic studies showed normal thyroid function. neck sonography revealed diffuse thickening and swelling of the fatty structures of both sides of the neck. Normal sonography showed no fatty deposition in the liver. Maxillary and neck computerized tomography revealed diffuse fat accumulation in the submental and posterior neck regions, with no extension to the superior mediastinum. Fine needle aspiration cytology of the neck masses showed only fat cells. The patient received an oral hypoglycemic agent (glibenclamide 5 mg bid) for blood glucose control and lovastatin (20 mg before bed-time) for hyperlipidemia, and ceased drinking alcohol. The neck swelling resolved markedly after 15 months of medical treatment. This suggests that, in addition to the cessation of alcohol consumption, the reduction of blood glucose and lipid concentrations by medication may also assist in resolving the accumulated fat of type I MSL in patients with NIDDM.- - - - - - - - - - ranking = 1.5keywords = glucose (Clic here for more details about this article) |

LABORATORY FINDINGS: Hemoglobin, 13.2 gm/dL; mean corpuscular volume, 80 micron 3; white blood cell count, 7,200/mm3 (normal differential); platelet count, 137,000/mm3. serum: electrolytes, normal; blood urea nitrogen, 18 mg/dL; creatinine, 0.8 mg/dL; glucose, 308 mg/dL; total protein, albumin, liver enzymes, and creatine kinase, normal. urine: 1 glucose. Venereal disease test: nonreactive; hiv test: negative. DIFFERENTIAL diagnosis: dermatomyositis; heavy-metal poisoning; diabetic amyotrophy. HOSPITAL COURSE: The patient was given 50 mg/day of oral amitriptyline to alleviate the painful paresthesias and was switched to 20 U/day of subcutaneously injected neutral protamine Hagedorn (NPH) insulin to normalize the blood glucose level. Histologic studies of skin and muscle showed sun damage and neuropathic changes, respectively. There was no evidence of vasculitis. Screening for heavy-metal toxins produced negative results.- - - - - - - - - - ranking = 1.5keywords = glucose (Clic here for more details about this article) |
5/219. Triglyceride-induced diabetes associated with familial lipoprotein lipase deficiency.Raised plasma triglycerides (TGs) and nonesterified fatty acid (NEFA) concentrations are thought to play a role in the pathogenesis of insulin-resistant diabetes. We report on two sisters with extreme hypertriglyceridemia and overt diabetes, in whom surgical normalization of TGs cured the diabetes. In all of the family members (parents, two affected sisters, ages 18 and 15 years, and an 11-year-old unaffected sister), we measured oral glucose tolerance, insulin sensitivity (by the euglycemic-hyperinsulinemic clamp technique), substrate oxidation (indirect calorimetry), endogenous glucose production (by the [6,6-2H2]glucose technique), and postheparin plasma lipoprotein lipase (LPL) activity. In addition, GC-clamped polymerase chain reaction-amplified dna from the promoter region and the 10 coding LPL gene exons were screened for nucleotide substitution. Two silent mutations were found in the father's exon 4 (Glu118 Glu) and in the mother's exon 8 (Thr361 Thr), while a nonsense mutation (Ser447 Ter) was detected in the mother's exon 9. Mutations in exons 4 and 8 were inherited by the two affected girls. At 1-2 years after the appearance of hyperchylomicronemia, both sisters developed hyperglycemia with severe insulin resistance. Because medical therapy (including high-dose insulin) failed to reduce plasma TGs or control glycemia, lipid malabsorption was surgically induced by a modified biliopancreatic diversion. Within 3 weeks of surgery, plasma TGs and NEFA and cholesterol levels were drastically lowered. Concurrently, fasting plasma glucose levels fell from 17 to 5 mmol/l (with no therapy), while insulin-stimulated glucose uptake, oxidation, and storage were all markedly improved. Throughout the observation period, plasma TG levels were closely correlated with both plasma glucose and insulin concentrations, as measured during the oral glucose tolerance test. These cases provide evidence that insulin-resistant diabetes can be caused by extremely high levels of TGs.- - - - - - - - - - ranking = 3.5keywords = glucose (Clic here for more details about this article) |
6/219. hepatitis a-induced diabetes mellitus, acute renal failure, and liver failure.A 38-year-old otherwise healthy man presented with hepatic failure (aspartate aminotransferase of 7212 U/L, alanine aminotransferase of 6629 U/L, total and direct bilirubin of 10.7 mg/dL) and acute renal failure (creatinine of 11.6 mg/dL and blood urea nitrogen of 42 mg/dL), which required hemodialysis when the creatinine increased to 21 mg/dL, with a blood urea nitrogen of 115 mg/dL, and the patient became oliguric. On admission, this patient also had a lipase of 1833 U/L, amylase of 211 U/L, glucose of 210 mg/dL, and reactive IgM antibody for acute hepatitis a. The hepatitis and acute renal failure resolved in 3 months, but this patient continues to have type II diabetes mellitus 7 years after the hepatitis a infection. This case illustrates that hepatitis a infection may be severe with liver failure, acute renal failure, and permanent diabetes mellitus as sequale of this infection.- - - - - - - - - - ranking = 0.5keywords = glucose (Clic here for more details about this article) |
7/219. Insulin and type 2 diabetes. Last resort or rational management?BACKGROUND: Recent evidence indicates that lower glucose levels in people with type 2 diabetes result in fewer complications. People with diabetes generally have sub-optimal glycaemic control. The natural progression of diabetes is characterised by increasing glucose levels requiring increasing therapy. OBJECTIVE: This article explores the possible role of therapeutic insulin in the management of type 2 diabetes. Arguments for earlier use of insulin, illustrative cases and common dilemmas faced when introducing insulin are examined. DISCUSSION: Findings from the United Kingdom Prospective Diabetes Study (UKPDS) are reviewed. It suggests that active and aggressive management of type 2 diabetes in general practice can have a role to play in reducing complications from diabetes. It now appears that insulin has a role earlier in the management of type 2 diabetes.- - - - - - - - - - ranking = 1keywords = glucose (Clic here for more details about this article) |
8/219. Providing timely and ongoing vision rehabilitation services for the diabetic patient with irreversible vision loss from diabetic retinopathy.BACKGROUND: diabetic retinopathy (DR) remains the leading contributor to severe vision loss in the united states among persons 20 to 70 years of age. Despite advances in disease management and treatment, patients with vision loss from DR continue to constitute a significant portion of patients served in vision rehabilitation service (VRS) settings. These patients present special challenges to VRS providers because of early onset, fluctuations in and the complex nature of vision loss, unique visual demands of disease management, and associated multi-system losses. case reports: After introductory epidemiologic review, a case presentation format is used to illustrate solutions a multidisciplinary VRS can offer the special visual challenges of the person with diabetes with vision loss from DR. Four patients are presented--ages 30 to 70 years--with varying degrees and types of vision loss, with different lifestyle demands and disease management needs. The cases address vocational issues, vision fluctuation, coordinating adaptive solutions to complex visual losses, and meeting diabetic needs to measure medication, insulin, and blood glucose levels, to maintain skin care, diet, exercise, transportation, family roles, and support systems. CONCLUSIONS: The unique and complex needs of people with diabetes who experience vision loss can be well addressed through timely and ongoing VRS consultations, in conjunction with medical/ocular disease management.- - - - - - - - - - ranking = 0.5keywords = glucose (Clic here for more details about this article) |
9/219. hypoglycemia associated with high doses of sertraline and sulphonylurea compound in a noninsulin-dependent diabetes mellitus patient.Unlike other selective serotonin reuptake inhibitors (SSRIs), sertraline has linear pharmacokinetics so that increases in dose lead to proportional increases in drug concentration. The half-life of sertraline is about 26 h so that it reaches a steady state in one week, according to the product monograph. hypoglycemia associated with sertraline and coadministration of oral hypoglycemics belonging to the sulphonylurea derivatives has rarely been reported. A patient with schizoaffective disorder with non-insulin-dependent diabetes mellitus (NIDDM) treated with sertraline, risperidone and glyburide who developed hypoglycemia is presented. The article highlights that inhibition of P450 enzymes can be affected by several different factors. Interactions are possible whenever a patient concomitantly receives two drugs that bind to the same P450 system Greater inhibition was likely induced at doses higher than those recommended. This process was reversed within 10 days of discontinuing the sertraline. Good glycemic control followed discontinuation of psychotropic drugs and the oral hypoglycemic agent. knowledge of the individual P450 enzymes is important in the metabolism of individual drugs, together with an understanding of the patient's drug metabolizing ability. These factors may lead to more appropriate prescribing and further research into specific P450 enzymes responsible for metabolism of particular drugs, which remains unclear.- - - - - - - - - - ranking = 0.012966244910081keywords = metabolism (Clic here for more details about this article) |
10/219. Hb Ube-2 in a diabetic case with an abnormally low HbA1C value.A 69-year-old male diabetic patient had an abnormally low HbA1C value of 2.8%, which was inconsistent with his elevated fasting plasma glucose of 8.2 mmol/l. Hb analysis disclosed that the abnormal Hb was Hb Ube-2 [alpha68 (E17) Asn --> Asp] and it accounted for 21.5% of the total Hb. Since the glycated abnormal Hb emerged at the same position as did HbF on high performance liquid chromatography, the HbA1C value was falsely low. The present case demonstrates that Hb Ube-2 is one of the abnormal Hbs in which caution should be exercised when monitoring diabetic control.- - - - - - - - - - ranking = 0.5keywords = glucose (Clic here for more details about this article) |
