Hepatic infarction rarely occurs due to the double supply of arterial and portal inflow. A 53-year-old man with diabetes mellitus developed multiple hepatic infarctions after an episode of fever and diarrhea. The infarction was documented by pathology after partial liver resection. Several causes of hepatic infarction may present in this patient: dehydration and hypotension caused by fever and diarrhea, type 2 diabetes and administration of glibenclamide, diabetic ketoacidosis and widespread atherosclerosis. We suggest that diabetic patient with elevated liver enzyme should be considered the possibility of hepatic infarction.

The spontaneously diabetic Torii (SDT) rat was recently recognized as a new animal model of non-obese type 2 diabetes. As the severe diabetic ocular complications seen in SDT rats already have been investigated, we examined another common diabetic complication, gastroenteropathy. Male SDT rats developed diabetes at 20 weeks and diarrhea at 28 weeks of age. Gastrointestinal motility was evaluated at 28 weeks by measuring the distance of small intestinal transit by oral administration of the non-absorbed marker, arabic gum. SDT rats exhibited greater intestinal transit distance than control SD rats (54.1+/-2.6% versus 43.0+/-1.2%). Insulin treatment of SDT rats begun at 20 weeks of age produced improved stool and reduced intestinal transit distance (41.4+/-0.3%). Morphologically, the SDT rats exhibited longer villi and heavier weight of intestine compared to control SD rats. These results suggest that the SDT rat may be a useful animal model for studies of diabetic gastroenteropathy.

Pseudomembranous colitis (PMC) is known to develop after antibiotic administration, but antituberculosis agents are rarely associated with this disorder. We report 6 cases of PMC after rifampicin administration; the clinical manifestations, laboratory findings, imaging findings, and clinical course are described. The median age of patients was 68 years (range, 54 to 82 y). All patients were diagnosed with active pulmonary tuberculosis by sputum smear and culture, and 2 suffered from type 2 diabetes mellitus. The average interval between initiation of antituberculosis therapy and the onset of diarrhea was 19.8 days. The anatomic distribution of PMC included the rectum and sigmoid colon in 5 cases and up to the hepatic flexure in 1 case. All patients were cured with medical treatment, which include discontinuation of rifampicin and oral metronidazole and vancomycin. PMC recurred in 1 patient after retreatment with rifampicin. Our findings suggest that patients who are treated with antituberculosis agents, who develop acute diarrhea during or after therapy, should be evaluated for PMC.

The incretin hormones are intestinal peptides that enhance insulin secretion following ingestion of nutrients. Liraglutide is a glucagon-like peptide-1 receptor analogue, which is obtained by derivatising glucagon-like peptide-1 with a fatty acid, providing a compound with pharmacokinetic properties that are suitable for once-daily dosing. Liraglutide has demonstrated lasting improvement of HbA(1c )levels, weight reduction and improved beta-cell function in patients with Type 2 diabetes mellitus. Liraglutide is well tolerated; the adverse events that are most frequently reported being transient nausea and diarrhoea. This article reviews the mechanisms of action and efficacy of liraglutide for the treatment of Type 2 diabetes mellitus. This agent is presently in Phase III clinical development.

Exenatide is the first drug in the incretin mimetic class and is indicated for treatment of type 2 diabetes mellitus. Although structurally similar to the native glucagon-like peptide, this synthetic form has a much longer duration of action. Randomized trials have shown exenatide to be efficacious in improving glycemic control when combined with either metformin or a sulfonylurea. The dose is initially 5 mcg subcutaneously twice daily and may be titrated to 10 mcg subcutaneously twice daily to achieve better diabetes management. Nausea, vomiting, and diarrhea were the most common adverse events reported with exenatide therapy. Exenatide is not associated with hypoglycemia, which may provide advantages over adding insulin to a sulfonylurea or metformin.

Type 2 diabetes mellitus is a common chronic disease that causes significant morbidity and mortality worldwide. The primary goal of treatment is to target glycemic control by maintaining the glycosylated hemoglobin level near 6-7% without predisposing patients to hypoglycemia. Diabetes results from a combination of increased hepatic glucose production, decreased insulin secretion from beta cells, and insulin resistance in the peripheral tissues. Currently available antidiabetic agents work by different mechanisms to lower blood glucose levels. Unfortunately, each of them has its tolerability and safety concerns that limit its use and dose titration. Sitagliptin is the first antidiabetic agent from the class of dipeptidyl peptidase-4 enzyme inhibitors. It increases the amount of circulating incretins, which stimulate insulin secretion and inhibit glucose production. Sitagliptin was approved by the US Food and Drug Administration (FDA) for use with diet and exercise to improve glycemic control in adult patients with type 2 diabetes. It can be used alone or in combination with metformin or a thiazolidinedione (pioglitazone or rosiglitazone) when treatment with either drug alone provides inadequate glucose control. The usual adult dose is 100 mg once daily. A dose of 25-50 mg once daily is recommended for patients with moderate-to-severe renal impairment. In randomized, placebo-controlled trials that lasted for up to 6 months, sitagliptin lowered glycosylated hemoglobin levels by 0.5-0.8%. In a 52-week clinical trial, sitagliptin was shown to be noninferior to glipizide as an add-on agent in patients inadequately controlled on metformin alone. Sitagliptin was well tolerated with the most common side effects being gastrointestinal complaints (up to 16%), including abdominal pain, nausea and diarrhea; hypoglycemia and body weight gain occurred at similar rates compared with placebo. Overall, sitagliptin provides a treatment option for patients with type 2 diabetes as a monotherapy, or as an adjunct to metformin or a thiazolidinedione when patients achieve inadequate glycemic control while on either of the agents. It is also an alternative therapy for those patients who have contraindications or intolerability to other antidiabetic agents.

Diabetic neuropathy is a common chronic complication of diabetes and cause of significant morbidity and mortality, because it may involve the autonomous and peripheral nervous systems. Autonomic diabetic neuropathy is a challenging chronic complication of long-standing diabetes manifested with hypotension, syncope, gastroparesis, diarrhea, constipation, bladder dysfunction, sexual dysfunction, cardiac arrest, and/or sudden death. We present a case of diabetic gastroparesis in an older woman. The patient was an 83-year-old woman with a 40-year history of type 2 diabetes who was admitted with hypoglycemia, malnutrition, persistent vomiting, and obstinate constipation. After several unsuccessful attempts with different therapies, we administered intravenous azithromycin (500 mg/day). After 3 days of treatment, vomiting was resolved and the patient evacuated normal feces, with notable improvement in the general conditions and metabolic control. Because diabetic gastroparesis frequently is difficult to manage clinically and there are few beneficial therapeutic choices available at present, the macrolide antibiotic azithromycin, which has strong prokinetic properties, may be a useful option in the treatment of this complex condition.

Postprandial hyperglycaemia and spikes have deleterious effects on Insulin secretion and sensitivity. The present study was undertaken to evaluate the efficacy, safety and tolerability of miglitol 50 mg three times daily for 12 weeks in 129 patients with type 2 diabetes mellitus, inadequately managed with diet and exercise therapy alone for 3 months after obtaining their written informed consent. The primary efficacy variables were per cent change from baseline at week 12 in fasting and postprandial plasma glucose concentrations and glycosylated haemoglobin (HbA(1C)) levels. After treatment at the end of 12 weeks mean reduction in fasting plasma glucose levels was 35.7% and 44.33% in postprandial plasma glucose levels while the mean HbA(1C) was significantly reduced by 0.88% (p<0.05). Total cholesterol, HDL, LDL and TC/HDL ratio did not showed any significant change but a non-significant reduction in triglyceride levels was observed in some patients. The mean body mass index was reduced non-significantly by 8% from baseline values. A total 19.5% patients treated with miglitol reported adverse events like flatulence, abdominal pain, nausea/vomiting, diarrhoea and dyspepsia. Only one patient reported hypoglycaemia. The results of the present study indicate that miglitol reduces fasting and postprandial plasma glucose levels, Improving glycaemic control, which is reflected in a reduced HbA(1C) level in patients with type 2 diabetes mellitus. It could be a useful first-line therapy in patients with type 2 diabetes mellitus inadequately controlled by diet alone and as adjuvant therapy in patients who are inadequately controlled with diet and sulfonylureas.

Metformin is a biguanide commonly used in type 2 diabetes mellitus (DM). Lactic acidosis, a potentially life-threatening metabolic disorder, may be due to a number of different causes, including metformin therapy. We present a case of a severe metformin-induced lactic acidosis in a patient with type 2 DM, admitted to the emergency department with a history of dehydration due to diarrhoea and complicated by acute renal failure. Patient complained malaise and severe weakness and was tachypneic (Kussmaul's respiration), agitated and confused, with a Glasgow Coma Scale score of 13/15. Heart rate was 75 b/min and blood pressure 110/80 mmHg. The pH was 6.87, HCO3- 3 mmol/l, lactate 15 mmol/l, potassium 6.9 mEq/l. The renal function was markedly impaired with a creatinine of 9.75 mg/dl, and pancreatic enzymes, amylase and lipase, were also increased in absence of abdominal pain. Patient was treated with intravenous fluids, bicarbonate infusion and haemodialysis with bicarbonate buffered replacement fluid. Clinical conditions improved rapidly, with a progressive normalization of the acid-base balance and the other laboratory data. Authors discuss the pathophysiologic mechanisms of these alterations with particular regard to the role played by metformin as potential cause of lactic acidosis.

Ingestion of Escherichia coli O157:H7 can cause a spectrum of acute illness, ranging from overt hemolytic-uremic syndrome (HUS), to gastroenteritis with bloody diarrhea, to no symptoms. This organism has been responsible for dozens of outbreaks of gastroenteritis and HUS in industrialized nations, and thus is a major public health concern. Although the acute effects of E. coli O157:H7 ingestion are well understood, the long-term complications are less well known. Here, we review the biological and empirical evidence supporting a link between E. coli O157:H7 and long-term diabetes mellitus. Survivors with diarrhea-associated HUS have a significantly increased incidence of diabetes due to complete insulin deficiency, which may recur several years after the initial infection. However, less severe forms of infection, such as E. coli O157:H7 gastroenteritis without overt HUS, do not appear to result in an increased risk of type 2 diabetes.
