The efficacy and safety of gliclazide (Diamicron) were studied in 29 NIDDM patients (19 men and 10 women aged 25-68 years) who failed to improve with diet or with diet plus a sulfonylurea. All patients were overweight and had fasting blood glucose levels consistently above 150 mg/dl (8.24 mmol/l). After withdrawal of oral hypoglycemics where applicable, they received 40 mg Diamicron three times daily with meals. The dose was increased by 40-80 mg/day until optimum control was obtained or up to a maximum of 320 mg/day. Treatment lasted for 12 months. At the end of this period the mean fasting blood glucose level had fallen by 35% from 238 to 154 mg/dl and the mean 2-h postprandial blood glucose level had fallen by 28% from 237.7 to 195 mg/dl. The mean glycosylated hemoglobin level also fell by 30% from 10.10 to 7.02%, i.e. within the normal range. In addition, there was a 19% fall in triglyceride and a 10% fall in cholesterol levels, with no change in body weight. No changes were observed for serum insulin, C-peptide and glucagon levels, thyroid function tests, blood counts, liver and kidney function tests, uric acid, electrolytes, blood pressure or heart rate. No clinical or ECG abnormalities were observed in patients with or without cardiovascular disease. There were two presumptive hypoglycemic reactions, but these did not require treatment. Adverse effects were reported by 22 patients, including dizziness and light-headedness, diarrhea, nausea, palpitations and pruritus, but none required modification of Diamicron therapy. The results therefore show that Diamicron is safe, effective and well tolerated in suitably selected NIDDM patients.

Although quinidine has been widely used since the beginning of the century, quinidine-induced hepatotoxicity has been recently reported in the literature. We describe a reversible case of quinidine-induced hepatotoxicity. A 62-y-old male with a past medical history of atrial flutter and adult onset diabetes was admitted to the hospital with a 3-d history of diarrhea, nausea, fever, chills and palpitations. Past medications included 7.5 mg glyburide daily for 4 y, 0.25 mg digoxin daily for 3 w, 324 mg quinidine gluconate 3 times daily for 2 w, and 150 mg papaverine daily for 2 y. On admission, liver enzyme levels were elevated (SGOT 606, SGPT 1104). Quinidine was considered an etiologic agent and was discontinued after administration of 1 dose. The patient became afebrile within 48 h, liver enzyme levels gradually decreased, and the patient was discharged on day 6 of hospitalization. Repeat enzyme levels obtained 12 d after discharge were mostly within normal limits. The symptoms were atypical as described in the literature. We conclude that unexplained fever or elevated liver enzyme levels should alert the clinician to the possibility of quinidine-induced hepatotoxicity.

Gastric emptying time was measured by ultrasonography in 18 NIDDM patients with and without autonomic neuropathy, evaluated by cardiovascular autonomic tests and in 10 controls before and after a physiologic test meal. Six neuropathic subjects showed gastrointestinal symptoms such as fullness and early satiety. Blood glucose, gastrin and pancreatic polypeptide were evaluated before and up to 200 min after the test meal. The gastric emptying rate was similar in controls (275 +/- 45 min) and in diabetic patients without (260 +/- 49 min) and with autonomic neuropathy (257 +/- 48 min) (p = ns), while diabetic symptomatics showed a significant reduction of gastric emptying rate (420 +/- 19.7 min) (p less than 0.001). Basal serum glucose concentration was similar in all diabetic patients (132 +/- 18 mg/dl, 166 +/- 52 mg/dl, 161 +/- 61 mg/dl, p = ns). A basal value of serum gastrin was similar in all groups while the test meal produced a rise with a peak at 40' significantly higher only in symptomatics (195 +/- 58 pg/ml vs control 107 +/- 88 pg/ml, diabetics without and with autonomic neuropathy: 98 +/- 12 pg/ml and 88 +/- 22 pg/ml respectively; p less than 0.01). Basal and stimulated PP values were similar in all groups. In conclusion ultrasonography is a simple, reliable method to evaluate gastric emptying rate without any interference in the mechanism of digestion and absorption of nutrients. The presence of non specific symptoms, such as nausea and gastric fullness, may indicate an early gastric involvement as supported by sonographic evidence of impaired emptying.

A 49-year-old man with an 11 year history of NIDDM presented hypercalcemic and with acute on chronic renal failure. His only symptoms were mild anorexia and nausea. Four years previously he had been diagnosed as having lipoid pneumonia, with classical histological findings. On this admission, serum parathyroid hormone was suppressed and 1,25 dihydroxyvitamin D levels elevated. The cause of his hypercalcemia presumably was ectopic 1 hydroxylation of 25 hydroxyvitamin D in the chronic granulomata in his lungs. It should be emphasised that any chronic granulomatous disease, and not just sarcoidosis, may be a cause of hypercalcemia.

To determine the frequency of gastrointestinal symptoms in diabetic patients, 190 patients, consecutively referred to the Diabetes Research Institute, reported their gastrointestinal symptoms on a standardized symptom list. One hundred and eighty non-diabetic healthy subjects served as (matched) controls. Finally, 75 patients with Type 1 (insulin-dependent) diabetes mellitus (33 male, 43 female; age 34,1 (18-60) yrs, diabetes duration: 11,1 (0,3-41) yrs) and 68 patients with Type 2 (non-insulin-dependent) diabetes mellitus (31 male, 37 female, age: 61,4 (37-88) yrs, diabetes duration: 10,7 (0,3-40) yrs) were studied and compared with two cohorts of controls of the same size. There were no differences in prevalence of symptoms referrable to the upper and lower GI-tract in type 1 diabetic patients as compared with controls. Among patients with type 2 diabetes the main gastrointestinal complaint was constipation (22,1% vs 10,3%; p < 0.05). Upper gastrointestinal symptoms were also more frequent among Type 2 diabetic subjects (nausea 11,8% vs 2,9%, p < 0.05). There was a tendency for an increased symptom prevalence with higher age in both type 1 and type 2 diabetes. Presence of peripheral neuropathy was associated with a higher symptom prevalence in type 1 diabetes. After stratification, diabetes duration and glycaemic control (HbA1c) did not influence the frequency of symptoms. Thus, gastrointestinal symptoms occur frequently among both diabetic patients and non-diabetic subjects. However, significant differences were found only in type 2 (non-insulin-dependent) diabetes, the commonest symptom being constipation. These findings support the need of a nondiabetic control group in epidemiological studies evaluating symptom prevalence in diabetes mellitus.

In patients with type 1 or type 2 diabetes mellitus disturbances of the gastrointestinal transit are well recognized. In decreasing order of frequency, transit disturbance through the colon, stomach, small intestine and esophagus as well as altered motility of the gallbladder occur. Acute changes of blood glucose concentrations have a major, however, reversible influence on motility in various parts of the intestinal tract. Long-term hyperglycemia may influence the incidence of gastrointestinal involvement via the occurrence of neuropathic changes of the autonomic nervous system. Early satiety, nausea, vomiting, weight loss, constipation, diarrhea and epigastric pain are often reported. These symptoms and recurrent episodes of hypoglycemia or prolonged hyperglycemia can result from intestinal transit disturbances.

A 45-year-old Mexican woman with a history of noninsulin dependent diabetes mellitus (NIDDM), hypertension, and coronary artery disease presented to the hospital after 2 months of intractable nausea, vomiting and diarrhea-all made worse by eating and drinking. She reported fever, chills, anorexia and a documented 50-pound weight loss during this period. She denied the signs and symptoms of melena, hematochezia, steatorrhea or constipation. She also reported left leg pain and decreased sensation and strength of her left leg compared to the right leg. She had been hospitalized 2 weeks prior to admission with the same symptoms and a diagnosis of viral gastroenteritis. She was also treated for H. pylori, but subsequent biopsy results were negative by Steiner stain.

The mechanism of action, pharmacokinetics, pharmacodynamics, clinical efficacy, and adverse effects of candesartan cilexetil are reviewed. Candesartan is an angiotensin II-receptor blocker (ARB). It is administered as a pro-drug that undergoes activation during gastrointestinal absorption. The agent is excreted mostly unchanged and has a terminal half-life of about nine hours (slightly longer in the elderly). Candesartan differs from other agents in its class in that it is tightly bound to angiotensin II type 1 receptors, allowing prolonged activity. In clinical trials, candesartan cilexetil has produced a dose-dependent effect when given in dosages of 2-32 mg/day. Observed trough-to-peak blood pressure ratios support a once-daily dosage regimen. The antihypertensive effect of candesartan cilexetil 4-16 mg/day was as great as that of enalapril 10-20 mg/day and amlodipine 5 mg/day and larger than that of losartan potassium 50 mg/day. Adding candesartan cilexetil to hydrochlorothiazide 12.5-25 mg/day and amlodipine 5 mg/day led to enhanced blood-pressure reductions and was well tolerated. It appears that candesartan can decrease renal perfusion without adversely affecting renal blood flow and may mediate a decrease in albuminuria in hypertensive patients with type 2 diabetes. No clinically important drug interactions have been reported. Adverse effects include headache, dizziness, nausea, diarrhea, and transient elevations in liver transaminases. The frequency of cough is similar to that seen with placebo. Candesartan cilexetil is an effective antihypertensive agent that can be used alone or in combination with other antihypertensive drugs. It is generally well tolerated and may be an option for patients who cannot tolerate angiotensin-converting-enzyme inhibitors because of cough.

The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, interactions, and dosage of nateglinide are reviewed. Nateglinide is an oral hypoglycemic agent approved for use alone or in combination with metformin as an adjunct to diet and exercise for the treatment of type 2 diabetes mellitus. Nateglinide, an amino acid derivative of D-phenylalanine, stimulates the secretion of insulin by binding to the ATP potassium channels in pancreatic beta cells. The result is an increase in beta-cell calcium influx, which leads to rapid, short-lived insulin release. The drug is rapidly and completely absorbed in the small intestine. The estimated bioavailability is 72%. Nateglinide is highly bound to plasma proteins, is metabolized extensively by the liver, and has an elimination half-life of 1.4 hours. Several clinical trials of nateglinide, alone and in combination with other oral hypoglycemic agents, have found the drug to be safe, effective, and well tolerated. The most common adverse effects are nausea, diarrhea, dizziness, and lightheadedness. There is a potential for interactions between nateglinide and medications affected by the cytochrome P-450 isoenzyme system. Dosage regimens ranging from 60 to 240 mg have been evaluated. The maximum effective dosage is 120 mg taken 10 minutes before meals three times a day. Nateglinide is an alternative to second-generation sulfonylureas for the treatment of type 2 diabetes mellitus. Additional comparative trials are needed to fully elucidate nateglinide's role.

A case of lipoma of the liver is reported in a 57-year-old woman with a 10-month history of non-insulin dependent diabetes mellitus and 3 days with abdominal pain, distention, nausea, and vomiting. On medical examination, the liver was palpable 5 cm below the right costal margin without splenomegaly or ascites. A CT scan revealed a well-defined fat attenuation tumor and an MR demonstrated a well-circumscribed lesion with bright signal intensity. An extended right hepatic lobectomy was performed. The resected specimen measured 28.6 x 18.3 x 8.2 cm and weighed 2,200 g. The yellow and well-circumscribed tumor measured 15 x 9.5 cm and was composed of mature adipose cells pushing the liver tissue at the periphery. The patient was asymptomatic 6 months after surgery.
