Designer insulins regimens in clinical practice--pilot multicenter Indian study.

BACKGROUND: Newer insulin analogues viz., premix insulin analogue (biphasic insulin aspart) and insulin glargine are now available in India. A multicenter all-India study was done to document the patient profile and responses to these analogues in routine clinical practice. METHODS: The study was conducted prospectively at 4 diabetes care clinics in different regions of India and collected data on the use of either of the two regimens A. Premix insulin analogue given twice-daily B. Basal-bolus analogue regimen (insulin aspart with every meal and insulin glargine once-a-day at bedtime). The centers collected all data at 3 time-points--baseline, 4 weeks later and end of 12 weeks. The study measures were FPG (fasting plasma glucose), PPPG (postprandial plasma glucose), HbA1c and insulin dose. FPG and PPPG were recorded at each of the three time points. HbA1c was recorded at baseline and end of study. Safety was assessed based on reported adverse drug reactions and occurrence of hypoglycaemias. RESULTS: Data of 145 patients was available for analysis (n=114 on premix insulin analogue and n=31 on basal-bolus analogue regimen). Baseline demography was comparable in the two groups. Both the regimens lowered all blood glucose parameters including HbA1c significantly as compared to baseline. However, the premix insulin analogue fared better than the basal-bolus regimen in lowering HbA1c (1.58 vs. 1.16% respectively; p<0.05). Also 41% more patients in the premix group could achieve target HbA1c of < 7% at the end of study. The mean insulin dose was lower with the premix analogue group at the end of 12 weeks. There was no significant difference between the two groups in terms of change in body weight. No major hypoglycaemias were reported and the percentage of patients experiencing a minor episode was lower with the premix analogue than the basal-bolus regimen both at 4 and 12 weeks (11.4 vs. 35.48%; 16.7 vs. 58.06% respectively). No adverse drug reactions were reported throughout the study. CONCLUSION: We conclude that both premix analogue administered twice a day and four times a day basal bolus regimen appear to be a convenient, safe and effective way of initiating insulin therapy in people with type-2 diabetes. The premix analogues achieves target better than the basal bolus regimen as has better compliance.

Conscious sedation as an anaesthetic technique in patients undergoing nonthoracotomy placement of automatic implantable cardioverter defibrillator: an initial experience.

Six adult patients with life threatening recurrent ventricular arrhythmias who underwent non- thoracotomy placement of automatic implantable cardioverter defibrillator under conscious sedation are reported. Our clinical experience, patient satisfaction, recovery profile, complications and cardiologist perception about the technique of conscious sedation is presented and discussed.

Medical arthroscopy--emerging era of rheumatological intervention.

OBJECTIVE: To evaluate the safety and diagnostic value of arthroscopy performed by a rheumatologist. METHODS: Decisions for performing arthroscopy were taken when detailed clinical history-and relevant rheumatological investigations failed to arrive at a definite diagnosis. Arthroscopies were performed under local anesthesia as a daycare procedure. Synovial biopsies taken during procedures were subjected to histopathological examination (HPE). RESULTS: Of the 50 patients enrolled, 39 were males while 11 were females with mean age of 35.5 years. In lower limb oligoarthritis group of patients, three had macroscopic picture of crystal arthropathy, rest of the 29 patients revealed gross picture indicative of non-specific synovitis. While in polyarticular group of eight patients, three had macroscopic picture suggestive of crystal arthropathy (probably polyarticlar gout) while five were indicative of rheumatoid arthritis. In monoarticular disease pattern (n= 10) macroscopic picture findings were as follows- crystal arthropathy-two, tubercular-three, synovial chondromatosis-one and non-specific synovitis-two. HPE of synovium did not correlate in many cases. CONCLUSION: Arthroscopy using a 4 mm scope under local anesthesia in the hands of rheumatologists is a safe daycare procedure. In few cases arthroscopy helped in arriving at a final diagnosis but many patients remained undiagnosed. Both the rheumatologists and the pathologists require further experience in this field.

Coronary artery disease pattern in the young.

Ninety-two patients aged 40 years or less with documented coronary artery disease were studied with special emphasis on risk factors, coronary angiographic patterns and left ventricular function. Tobacco consumption was the most common risk factor (54%) followed by family history of coronary artery disease (40%). Hyperlipidaemia was not a frequent risk factor. Significant single vessel disease was present in 29% of patients. The incidence of double vessel and triple vessel disease was much higher. The left anterior descending artery was the most commonly involved vessel followed by right and circumflex coronary arteries. Left ventricular function as determined by ejection fraction was abnormal in 51% of patients; left ventricular end diastolic pressure was abnormal in 28% of patients. Sixty-eight percent of patients with no risk factors had either zero vessel or single vessel disease indicating a positive relationship between occurrence of risk factors and significant coronary artery disease in the young.
