Evaluation of the efficacy and safety of Diamicron in non-insulin-dependent diabetic patients.

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.

Hematological and biochemical changes in water buffalo calves (Bubalus bubalis) infected with Trypanosoma evansi.

Four water buffalo calves (Bubalus bubalis) were each inoculated intravenously with 10(6)T. evansi (camel isolate) and the fifth calf kept as non-infected control. The blood and sera of all calves were examined every 4 days during the first month post-inoculation (pi) and then once weekly until the end of the experiment (88 days pi). They were examined for hematological and biochemical changes, liver and kidney function tests. Hemoglobin concentration (Hb%), packed cell volume (PCV) and red blood cell count were significantly decreased. Total leucocytic count, lymphocytes and monocytes showed significant increase. Liver function tests revealed significant elevation in the activity of lactate dehydrogenase enzyme (LDH), globulin, total biliruben and indirect biliruben while alkaline phosphatase enzyme showed significant decrease. Kidney function tests revealed significant decrease of both creatinine and urea.

[Kidney function in test subjects: published results and clinical relevance].

Sevoflurane degrades in CO2 absorbents to produce compound A, which may have hepatotoxic potential in humans. Several recent studies in human volunteers have been performed to evaluate this potential. Three studies have evaluated sevoflurane administered to volunteers using a 3% concentration for 8 h duration at approximately 2 L/min flow rate. The initial investigation found high excretion of protein, glucose and renal tubular enzymes in the urine of the volunteers receiving sevoflurane. Subsequent investigations using identical protocols found more minor or absent changes in excretion of these markers. One additional investigation in volunteers studied 3% sevoflurane anesthesia for 4 h duration using a low-flow (1 L/min) technique. No significant excretion of protein, glucose or renal enzymes was observed. Application of these results to clinical practice must be interpreted in light of the experimental nature of the anesthetic administration. Although some controversy remains, these data, combined with results of recent studies in surgical patients, suggest that renal function following modest duration low-flow sevoflurane anesthesia is similar to that following isoflurane anesthesia.
