Item Atorvastatin improves arterial stiffness in normotensive normolipidaemic persons with type 2 diabetes.(2008-11-17) Mukherjee, Sarmistha; Mukhopadhyay, Pradip; Pandit, Kaushik; Mukherjee, Satinath; Chowdhury, SubhankarIncreased arterial stiffness is an independent predictor of cardiovascular disease and mortality in middle-aged and olderadults. We measured arterial stiffness by pulse wave velocity (PWV)in brachial-ankle segments by automated oscillometry in 71 normotensive and normolipidaemic subjects with type 2 diabetes (40 males and 31 females). 57 patients (whose baPWV was more than 1400 cm/second) were randomised into two groups, group A (n=29) were given 10 mg atorvastatin daily for 6 months and group B (n=28) were given placebo. After 6 months, atorvastatin group had significant improvement in brachial-ankle pulse wave velocity (baPWV) (1712.03 +/- 349.9 cm/second versus 1558.81 +/- 303.26 cm/ second, p< 0.05). Though the placebo group showed some improvement (1692.03 +/- 425.15 cm/second versus 1636.78 +/- 425.1 cm/second) it was not statistically significant. Despite correlation was noted between baPWV and systolic blood pressure (SBP), there was no significant correlation between the mean baPWV and duration of diabetes, body mass index (BMI), waist circumference, waist-hip ratio (WHR), waist to height ratio (WHtR), glycated haemoglobin (HbA1c), LDL, HDL cholesterol and spot urine albumin creatinine ratio (ACR) at the baseline. The decrement of LDL-cholesterol is correlated with the decrement of the baPWV in the atorvastatin group only (p<0.01).Item Authors’ response.(2014-06) Dutta, Deep; Maisnam, Indira; Shrivastava, Ankit; Sinha, Anirban; Ghosh, Sujoy; Mukhopadhyay, Pradip; Mukhopadhyay, Satinath; Chowdhury, SubhankarItem Authors’ response.(2014-06) Dutta, Deep; Maisnam, Indira; Shrivastava, Ankit; Sinha, Anirban; Ghosh, Sujoy; Mukhopadhyay, Pradip; Mukhopadhyay, Satinath; Chowdhury, SubhankarItem Drug therapy in prediabetes.(2005-11-31) Mukhopadhyay, Pradip; Chowdhury, SubhankarPatients with impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) have been designated by American Diabetes Association (ADA, 2004) as having 'prediabetes', which indicates the higher risk of developing the disease in these patients. Prediabetes is important to recognise because of at least 2 major implications: increased risk for future diabetes and for atherosclerotic cardiovascular diseases. Pharmacotherapy in prediabetes should therefore be directed at preventing or, at least, delaying the onset of the disease as well as reducing the morbidity and mortality from atherosclerotic complications. Several drugs having different mechanisms of action, such as metformin, glitazones, acarbose, orlistat, nateglinide, glicazide, angiotensin-converting enzymes, angiotensin receptor blockers have been found to be effective in prediabetes to improve the glycaemic status, though they are still not recommended by any professional organisation.Item Insulin therapy--role beyond glucose control.(2004-10-13) Pandit, Kaushik; Mukhopadhyay, PradipLarger studies had shown improved patient outcome and lower probability of coronary artery disease in insulin treated groups. The classical lipid abnormalities associated with type 2 diabetes are low HDL-cholesterol concentration and high triglyceride concentration. Insulin usage leads to a decrease in triglyceride concentration, primarily by its effect on the enzyme adipose tissue lipoprotein lipase. Insulin suppresses the enzyme, thereby controlling lipolysis in uncontrolled diabetes. Insulins therapy also improves the endothelial dysfunction especially in people with evident macrovascular complications. Though insulin is noted to increase adrenergic tone and may cause elevation of blood pressure, still patients with insulinoma do not have high blood pressure. Some studies suggest weight gain with insulin therapy, others contradict it. One study suggests that insulin does not affect treatment satisfaction. Insulin is known to improve the glycaemic scenario and also the insulin secretory pattern by reducing the glucotoxicity.Item Management of diabetic gastroparesis.(2005-03-22) Mukhopadhyay, Pradip; Basu, A KDiabetic gastroparesis is a long term complication of diabetes mellitus which could basically be defined as dysregulated gastric emptying leading to various pathological, biochemical and clinical changes in absence of any structural changes. Symptoms include nausea, vomiting, bloating, epigastric pain, anorexia, weight loss and so on. For symptomatic gastroparesis prokinetic drugs like metoclopramide, domperidone, cisapride, erythromycin and itcopride are used. Itopride is currently emerging as a prokinetic drug of choice. There is also scope of surgery.Item Profile of hypopituitarism in a tertiary care hospital of eastern India--is quality of life different in patients with growth hormone deficiency?(2008-06-09) Chatterjee, Purushottrram; Mukhopadhyay, Pradip; Pandit, Kaushik; Roychowdhury, Bibek; Sarkar, Dasarathi; Mukherjee, Satinath; Chowdhury, SubhankarHypopituitarism is of diverse aetiology. Apart from pituitary adenoma and Sheehan's syndrome, snakebite is a common aetiology of hypopituitarism. A total of 82 patients of hypopituitarism were studied. Biochemical and radiological investigations were done in all the cases. A quality of life questionnaire was put among the patients. Scores were calculated from the answers of the questionnaire and they were assessed about quality of life. Though growth hormone deficiency is associated with poor quality of life there were no significant differences with patients with hypopituitarism without any growth hormone deficiency.Item Serum vitamin-D predicts insulin resistance in individuals with prediabetes.(2013-12) Dutta, Deep; Maisnam, Indira; Shrivastava, Ankit; Sinha, Anirban; Ghosh, Sujoy; Mukhopadhyay, Pradip; Mukhopadhyay, Satinath; Chowdhury, SubhankarBackground & objectives: Patients with diabetes and vitamin-D insufficiency have increased insulin resistance. Similar observations among individuals with prediabetes are not well documented. The aim of this study was to find the occurrence of vitamin-D insufficiency/deficiency among individuals with prediabetes and to evaluate the relationship between vitamin-D status and insulin resistance. Methods: One hundred fifty seven individuals with prediabetes who fulfilled all the inclusion and exclusion criteria underwent clinical examination, anthropometric measurements (waist circumference, waist-hip ratio, waist-height ratio) and blood sampling after overnight fast for estimation of fasting blood glucose, fasting insulin, 25(OH)vitamin-D, intact parathyroid hormone (iPTH) and lipid profile. One hour post 75 g glucose (1hPG) blood glucose during oral glucose tolerance test was measured. Results: Vitamin-D deficiency/insufficiency was found in 115 (73.25%) individuals with prediabetes. Severe vitamin-D deficiency (<10 ng/ml) was seen in 14.65 per cent individuals. Individuals with the lowest vitamin-D levels (<10 ng/ml) had the highest insulin resistance (HOMA2-IR: 2.04 ± 0.67). Serum 25(OH)D had a statistically significant inverse correlation with insulin resistance (HOMA2-IR; r=-0.33; P=0.008), and positive correlation with insulin sensitivity (QUICKI; r=0.39; P=0.002), after adjusting for BMI and HbA1c. There was no correlation between vitamin-D status and estimated beta cell mass (HOMA-β). The mean waist-height ratio among individuals with prediabetes was 0.57 (normal<0.5) indicating a high risk of cardiovascular morbidity. Individuals with elevated 1hPG>155 mg/dl had significantly higher BMI and worse insulin resistance, and 1hPG correlated well with 2 hour post glucose blood glucose (r=0.57; P<0.001). Interpretations & conclusions: Vitamin-D deficiency/insufficiency may have some role in the development/worsening of insulin resistance in individuals with prediabetes in our country who have a high cardiovascular risk. Prospective studies on a large group of individuals need to be done to confirm the findings.Item A study of aspirin resistance in type 2 diabetes.(2008-11-17) Singla, Mani Kant; Lahiri, Prabir; Mukhopadhyay, Pradip; Pandit, Kaushik; Chaudhuri, Utpal; Chowdhury, SubhankarAspirin is currently known to give inadequate protection against coronary artery disease in diabetes compared to person without it. We evaluated 97 consecutive patients with type 2 diabetes for assessing laboratory aspirin resistance and attempted to assess the impact of various clinical and biochemical parameters on it. Thirty-eight patients (39.1%) were found to be less sensitive to the action of aspirin, 7 persons (7.2%) were found to be resistant and 31 persons (31.9%) were aspirin semi-responders. Only total cholesterol, LDL-cholesterol and triglyceride had statistically significant impact on aspirin resistance (p<0.05). Three persons out of 9 with some form of macrovascular disease had aspirin resistance.Item A study on endocrine changes in patients in intensive care unit.(2008-06-09) Sahana, Pranab Kumar; Ghosh, Asutosh; Mukhopadhyay, Pradip; Pandit, Kaushik; Chowdhury, Bibek Roy; Chowdhury, SubhankarPattern of endocrine changes in moderate to severely ill patients in a medical intensive care unit, correlation with the severity of illness and whether these changes can predict outcome of the critically ill patients were evaluated and studied in 80 patients admitted with acute physiology and chronic health evaluation (APACHE) II score >10 and without any pre-existing endocrinopathies or on drugs likely to affect the endocrine axis. Adrenal insufficiency was present in 45%, and mortality was higher in those with lower (<15 microg/dl) and higher (>30 microg/dl) serum cortisol. Sick euthyroid syndrome was detected in 80%, and those with low mean T3 (<0.6 ng/ml), free T4 (<0.89 ng/dl) and total T4 (<4 microg/dl) and had increased mortality. Hypotestosteronaemia was found in 92% of men and was significantly associated with severity of illness in men. Though prolactin is the first hormone to be elevated, there was no correlation between prolactin and severity of illness or mortality.
