RESUMEN
OBJECTIVE: The present study was a prospective, parallel group, open-labeled, comparative, multicentric, active controlled study to evaluate the safety, tolerability and benefits of fixed dose combination of acarbose and metformin versus metformin alone in type 2 diabetic patients. METHODS: A total of 229 patients with type 2 diabetes were enrolled at 5 medical centers across India. They received either acarbose (50 mg) + metformin (500 mg) bid/tid (n=115) or metformin monotherapy (500 mg) bid/ tid (n=114) for 12 weeks. Primary objective was to evaluate safety and tolerability based on the adverse events reported. Secondary objective was efficacy assessment based on changes in fasting, post prandial blood glucose and HbA1c values. RESULTS: In the acarbose + metformin group 10 patients reported 14 adverse events while in metformin group 9 patients reported 10 adverse events. No patient reported any serious adverse event or was withdraw from study because of adverse events. In the acarbose plus metformin group fasting blood glucose (FBG) decreased from a baseline of 158.85 +/- 18.14 mg/dl to 113.55 +/- 19.38 mg/dl (p < 0.0001) (decrease of 45.30 +/- 15.30 mg/dl) at 12 weeks, while in the metformin group fasting blood glucose decreased from a baseline of 158.31 +/- 26.53 mg/dl to 130.55 +/- 28.31 mg/dl (p < 0.0001) (decrease of 27.76 +/- 22.91 mg/dl) at 12 weeks. In the acarbose plus metformin group postprandial blood glucose (PPBG) decreased from a baseline of 264.65 +/- 34.03 mg/dl to 173.22 +/- 31.40 mg/dl (p < 0.0001) (decrease of 91.43 +/- 28.65 mg/dl) at 12 weeks, while in the metformin group PPBG decreased from a baseline of 253.56 +/- 36.28 mg/dl to 205.36 +/- 39.49 mg/dl (p < 0.0001) (decrease of 48.20 +/- 32.72 mg/dl) at 12 weeks. In the acarbose plus metformin group glycosylated haemoglobin (HbA1c) decreased from a baseline of 9.47 +/- 0.69% to 7.71 +/- 0.85% (p < 0.0001) (% decrease of 1.76 +/- 1.11) at 12 weeks, while in the metformin group HbAlc decreased from a baseline of 9.32 +/- 0.65% to 8.26 +/- 0.68% (p < 0.0001) (% decrease of 1.06 +/- 0.66) at 12 weeks. The combination of acarbose and metformin was found to be significantly superior in lowering the FBC (p < 0.0001), PPBG (p < 0.0001) and HbA1c (p < 0.0001) at 12 weeks as compared to metformin monotherapy. CONCLUSIONS: Fixed dose combination of acarbose and metformin was well tolerated and it was superior to metformin monotherapy in controlling FBG, PPBG and HbA(1C) levels in Type 2 Diabetes Mellitus patients.

OBJECTIVE: To compare the efficacy, safety, and tolerability of Epalrestat with Methylcobalamine in patients with diabetic neuropathy. MATERIALS AND METHODS: This prospective, open-labeled, comparative, and multicentric study was conducted on an outpatient basis by qualified investigators at four different centers. A total of 242 patients with diabetic neuropathy were enrolled in the study. The enrollment of patients was as per inclusion/exclusion criteria. After obtaining their informed consent, they were individually interviewed, examined, investigated, and treated as per the study protocol. Each patient was administered with one tablet containing Epalrestat 50 mg thrice daily or Methylcobalamine 500 microg thrice daily for 12 weeks. They were followed up at the end of weeks 4, 8, and 12 for their examination. Therapeutic success was assessed in terms of clinical symptoms, physical examinations, and electrophysiological assessments. RESULTS: A significant improvement in all the efficacy parameters was observed with Epalrestat treatment compared to Methylcobalamin treatment. The efficacy parameters assessed were loss of sensation, burning sensation, numbness, muscle cramps, spontaneous pain, weakness, mean score of isometric muscle strength, tendon reflexes, and sensation. Epalrestat treatment is associated with very few adverse events. The tolerability to Epalrestat treatment was also reported to be excellent in the majority of the study population compared to tolerability to Methylcobalamine. Patients as well as physicians reported that the Epalrestat treatment is superior in efficacy and safety parameters compared to Methylcobalamin. CONCLUSION: The present study concludes that Epalrestat has better efficacy and safety profile than Methylcobalamine in the treatment of diabetic neuropathy.
RESUMEN
BACKGROUND: The treatment of tuberculosis (TB) with category I regimen of the Revised National Tuberculosis Control Programme (RNTCP) for patients with diabetes mellitus (DM) needs evaluation. OBJECTIVE: To assess the cure and relapse rates in 3 years, among the new smear-positive TB patients with Type-2 DM (DMTB) treated with CAT-I regimen (2E3H3R3Z3/4R3H3) of RNTCP. METHODOLOGY: TB suspects attending the diabetology units and the TB research centre (TRC) Chennai, were investigated. Eligible DMTB cases were enrolled. Baseline estimation of cardiac, renal, liver function tests and glycosylated-HBA1c were undertaken. All patients received 2E3H3R3Z3/4R3H3 under supervision at TRC. Clinical and sputum (smear and culture) examinations and monitoring of diabetic status were undertaken every month up to 24 months, then once in 3 months up to 36 months. RESULTS: Of 100 patients admitted, 7 were excluded for various reasons from analysis. Of 93 patients, 87 (94%) had a favourable response at the end of treatment. Pre and post treatment mean glycosylated-HBA1c were 9.7% and 8.4% (>7% poor control). During follow-up period, 6 died and one lost to follow-up. Of the remaining, four relapsed. CONCLUSION: Category-I regimen, recommended for all the new smear-positive patients in the Indian TB programme, is effective in the treatment of DMTB patients, despite poor control of diabetes.

To evaluate efficacy and tolerability of telmisartan, an angiotensim II receptor blocker, in reducing microalbuminuria in adult Indian hypertensive patients with type 2 diabetes mellitus, a prospective, open-label, non-comparative, assessor-blind, multicentric, pilot study was conducted in 60 eligible hypertensive patients with type 2 diabetes mellitus and microalbuminuria after obtaining their informed consent. The study was approved by the respective institutional review boards. Each patient received telmisartan 40 mg initially once daily for first 4 weeks which was titrated upwards to 80 mg once daily for the next 8 weeks. Blood pressure was assessed at the end of every 2 weeks and urinary albumin excretion and creatinine clearance were measured at baseline and after 12 weeks of therapy. Safety outcome measures included monitoring of physical examination, laboratory parameters and monitoring treatment-emergent adverse events. Fifty-five patients completed the study while 5 cases were lost to follow-up. The mean age of the patients was 48.27 years. Of the total patients 63.6% were males and 46.4% were females. At baseline the mean urinary albumin excretion rate was 131.81 +/- 38.82 mg/minute. A statistically significant (p < 0.05) reduction (32.96%) in urinary albumin excretion rate occurred after 12 weeks of therapy (118.36 +/- 37.22). The mean pre-study systolic blood pressure was 165.05 +/- 15.24 mmHg which was significantly (p < 0.05) reduced to 123.72 +/- 5.88 mmHg at the end of 12 weeks. At baseline the mean diastolic blood pressure was 103.55 +/- 9.84 mmHg which was significantly (p < 0.05) reduced to 84.71 +/- 8.54 mmHg. The JNC-VII goal of blood pressure below 130/80 was achieved in 34 (61.8%)of the 55 patients at the end of 12 weeks. Both fasting and postprandial blood sugar levels were well-controlled at the end of the study. Telmisartan was well tolerated with only 9.09% of the patients reported mild and transient adverse events like fatigue, dizziness, nausea and diarrhoea. No abnormalities were detected in the laboratory parameters. The results of this pilot study indicate that telmisartan is effective, safe and well tolerated while reducing microalbuminuria in adult Indian hypertensive patients with type 2 diabetes mellitus.
