1/33. Patient case studies.Three contrasting cases of obese patients with type 2 diabetes mellitus are presented, which illustrate the management difficulties faced by clinicians. The first raises the issue of when to commence an oral hypoglycaemic agent in a newly diagnosed but asymptomatic obese patient; the second case addresses the problem of when to commence insulin in the face of continuing weight gain and poor glycaemic control; the final case is an example of the vicious metabolic spiral which so many patients enter, with increasing body weight, poor diabetic control and associated co-morbidities. The discussion that follows each case presentation recognises the considerable cardiovascular risk faced by such patients and provides guidance about possible management pathways including adjunctive anti-obesity pharmacotherapy.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
2/33. Bone amyloidoma in a diabetic patient with morbid obesity.Bone localisations of amyloidosis are rare, usually diffuse and associated with myeloma. We report the case of a patient with massive obesity complicated by diabetes, hypertension, sleep apnea and liver steatosis, who complained of rapidly worsening bilateral polyradiculalgia of the lower limbs. After sufficient weight loss made nuclear magnetic resonance imaging feasible, a spinal tumour was visualised on the 5th lumbar vertebra, extending to soft tissues. Total excision was performed, and pathological studies revealed an amyloid bone tumour with no evidence of myeloma.- - - - - - - - - - ranking = 5keywords = obesity (Clic here for more details about this article) |
3/33. A case of obesity, diabetes and hypertension treated with very low calorie diet (VLCD) followed by successful pregnancy with intrauterine insemination (IUI).The patient was a 32-year-old obese woman with a history of type 2 diabetes and hypertension for 6 years. Although she was treated with antihypertensive agents and intensive insulin therapy, her hyperglycemia was difficult to control. She wanted to have a baby but pregnancy was not recommended because her diabetes was under poor control and the use of antihypertensive medication. To achieve good control of obesity, diabetes and hypertension, she was admitted to our clinical department for weight reduction using very low calorie diet (VLCD). During VLCD she had a 19.8 kg reduction in body weight and her blood glucose and blood pressure were in good control without the use of drugs. Five months later, she became pregnant after the fourth trial of intrauterine insemination (IUI) and gave birth to a female baby under insulin therapy. This is the first report that showed the usefulness of VLCD for prepregnant control of glucose metabolism and blood pressure in an obese hypertensive patient with type 2 diabetes mellitus.- - - - - - - - - - ranking = 5keywords = obesity (Clic here for more details about this article) |
4/33. Olanzapine-induced diabetes mellitus.OBJECTIVE: To report two cases of new-onset diabetes mellitus resulting after the initiation of olanzapine treatment. CASE SUMMARY: A 31-year-old African American man and a 44-year-old white man, both with schizoaffective disorder, developed diabetes mellitus within weeks or months of olanzapine initiation. DISCUSSION: Our reports of new-onset diabetes due to olanzapine are consistent with those in the literature. Although the mechanism is not yet known, it has been hypothesized that perhaps damage to the pancreatic islet cells, weight gain, dysregulation of the sympathetic system, and insulin resistance are contributing factors. CONCLUSIONS: diabetes mellitus secondary to olanzapine use seems to be a rare occurrence. However, certain risk factors such as obesity, family history, and concomitant medications may predispose an individual to development of diabetes mellitus while taking olanzapine. An increased awareness of this reaction is essential in the treatment of patients at risk. Periodic serum glucose monitoring in these individuals may be warranted.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
5/33. Ophthalmologic and systemic features of the alstrom syndrome: report of 9 cases.The alstrom syndrome is a rare autosomal recessive disorder characterized by pigmentary retinopathy, diabetes mellitus, sensorineural deafness and obesity. A normal intelligence is often present. We report 9 patients.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
6/33. Type 2 diabetes in obese white children.We report four white adolescents aged 13 to 15 years (three females, one male) from the south and west region of england who presented with type 2 diabetes mellitus associated with significant obesity (body mass index more than 3SDS) in the past two years. Although these are the first reported obese, white cases from the UK to present with diabetes, we believe this clinical scenario will become more prevalent given the epidemic of childhood obesity in this country.- - - - - - - - - - ranking = 2keywords = obesity (Clic here for more details about this article) |
7/33. Evaluation of insulin resistant diabetes mellitus in alstrom syndrome: a long-term prospective follow-up of three siblings.alstrom syndrome is a rare cause of diabetes mellitus. We studied two generations of a Turkish family in whom four members were affected by alstrom syndrome. The natural course of the syndrome in three sisters was followed for 13 yr. The three sisters had short stature and truncal obesity, and developed complete blindness due to retinitis pigmentosa at 10, 5 and 13 yr of age. Two had sensorineural hearing loss and mild mental retardation, while the other developed diabetic ketoacidosis (DKA) at 14 yr and was treated with insulin from onset of diabetes. In the second case, diagnosis of diabetes was made by an OGTT at age 20 yr, and controlled with diet alone for 11 yr, then with a sulphonylurea for 2.5 yr, then with insulin. The third case developed acute hyperglycaemia at 20 yr, and required insulin from onset. Moreover, transitional features of impaired carbohydrate and fat metabolism (severe hyperinsulinaemia and insulin resistance progressing to islet beta cell failure, and hypertriglyceridaemia with fatty liver) were demonstrated, in accord with the literature. Previously unreported findings characteristic of nephro-uropathy with early-onset hypertension were also detected, and included in all cases proteinuria, glomerulopathy, and abnormal locations of the kidneys, narrowed uretero-renal junctions and dilated ureters.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
8/33. Recurrent and de novo non-alcoholic steatohepatitis following orthotopic liver transplantation.BACKGROUND: Non-alcoholic steatohepatitis was coined in 1980 to describe pathological and clinical features of non-alcoholic disease associated with pathological features, commonly seen in alcoholic-liver disease itself. It is now a well-recognised cause of end-stage liver disease and a rare cause of orthotopic liver transplantation. A small number of cases with recurrent non-alcoholic steatohepatitis following liver transplantation have been reported, however de novo non-alcoholic steatohepatitis in the liver allograft is not well recognised. AIMS/RESULTS: We report four cases of non-alcoholic steatohepatitis following orthotopic liver transplantation describing the factors related with the pathology. The recurrence of fatty infiltration occurred within 21 months and transition from mild steatosis to non-alcoholic steatohepatitis and early fibrosis was observed within 60 months post transplant in all four patients. All four cases had association with one or multiples risk factors (obesity, type 2 diabetes and/or hyperlipidemia). CONCLUSIONS: Management of this risk factors may play a therapeutic role in the prevention of recurrent and de novo non-alcoholic steatohepatitis following orthotopic liver transplantation.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
9/33. Maternal uniparental disomy for chromosome 14 with diabetes mellitus.A 20-year-old Japanese man was admitted to our hospital because of thirst and weight loss. His fasting plasma glucose, glycated hemoglobin, and urinary c-peptide were 262 mg/dl, 13.6%, and 44.8 microg/day, respectively, and the autoimmune antibodies related to type 1 diabetes were negative. Chromosome analysis of his peripheral blood lymphocytes showed a mos45,XY,der(14;14)(q10;ql0)[129]/ 46,XY, 14, der(14;14)(q10;q10)[1] karyotype. His parents were karyotypically normal. Microsatellite marker analysis on chromosome 14 demonstrated mosaic maternal segmental isodisomy for 14q21-q24. Although the parents had normal glucose regulation, the patient who finally returned to impaired glucose tolerance and his mother both have a deficiency in early postprandial insulin secretion. Since obesity was mild (body mass index, 24.1 kg/m2) and he was relatively young for type 2 diabetes, we speculated that his isodisomy 14 may have been involved in the onset of diabetes mellitus in this patient.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
10/33. Clinical features of a young Japanese woman having marked obesity and abrupt onset of diabetes mellitus with ketoacidosis.The subject was a 26-year-old Japanese woman of 148 cm height, 96.2 kg of body weight (BW) (body mass index (BMI) of 43.8 kg/m(2)). She was referred to our hospital on May 1, 2000 for the evaluation of marked hyperglycemia with clinical symptom of general malaise, polydipsia, and ketonuria (3 ). She did not smoke, or drink alcohol. But, she tended to eat lots of sweet food every day before the onset of this symptom. Her father was diagnosed type 2 diabetes mellitus. Her fasting plasma glucose and HbA(1c), and serum c-peptide were 398 mg/dl, 7.8% and less than 0.05 ng/ml [normal range: 0.94-2.8], respectively. She tested negative for anti-glutamic acid decarboxylase (GAD) antibodies and islet-cell antibodies. c-peptide level in her urine was as low as 3.4 microg/day. We immediately started insulin treatment under the diagnosis of abrupt onset of diabetes mellitus with diabetic ketoacidosis on the day of her admission, and the insulin treatment was continued after her being discharged. She showed continuous BW reduction until her BW reached approximately 60 kg, followed by her BW being plateau. During the period, intra-abdominal visceral fat (VF) and subcutaneous fat (SF) volume assessed by helical computerized tomography (CT) showed a substantial reduction [3.9-0.5 l for VF, 19-3.2 l for SF volume]. Pre-heparin plasma lipoprotein lipase (LPL) mass showed a considerably lower value when she had continuous BW reduction than did it when her BW reduction discontinued. These findings suggest that in this subject, continuous BW reduction after the abrupt onset of diabetes is closely associated with intra-abdominal fat mass reduction, which may be related to decreased production of LPL.- - - - - - - - - - ranking = 4keywords = obesity (Clic here for more details about this article) |
