abstract
Background: The Achieve, a multicentric (28 countries), 24-week, non-interventional study evaluated the safety and effectiveness of insulin detemir, biphasic insulin aspart and insulin aspart in people with T2DM (n = 66,726) in routine clinical care across four continents. Materials and Methods: Data was collected at baseline, 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled from West Bengal, India. Results: A total of 1133 patients were enrolled in the study. Four different insulin analogue regimens were used in the study. Patients had started on or were switched to biphasic insulin aspart (n = 897), insulin detemir (n = 94), insulin aspart (n = 90), basal insulin plus insulin aspart (n = 28) and other insulin combinations (n = 19). At baseline glycaemic control was poor for both insulin naïve (mean HbA1c: 8.5%) and insulin user (mean HbA1c: 8.9%) groups. After 24 weeks of treatment, both the study groups showed improvement in HbA1c (insulin naïve: -1.3%, insulin users: -1.6%). SADRs including major hypoglycaemic events or episodes did not occur in any of the study patients. Conclusion: Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia.

Introduction
62.4 million Indians were reported to have type 2 diabetes mellitus (T2DM) putting India on the forefront of diabetic epidemic across globe.[1,2] Fear of hypoglycaemia and gain in body weight are barriers for initiation of insulin therapy.[3] Modern insulin analogues are a convenient new approach or tool to glycaemic control, associated with low number of hypoglycaemia and favourable weight change.[4] Achieve, a multinational, 24-week, non-interventional study, assessed the safety and effectiveness of insulin analogues in people

with T2DM (n = 66,726) in routine clinical care.[5] This short communication presents the results for patients enrolled from West Bengal, India.

Results
A total of 1133 patients were enrolled in the study. The patient characteristics for the entire cohort divided as insulin-nai've and insulin users is shown in the Table 1. Glycaemic control at baseline was poor in this population. The majority of patients (79.2%) started on or switched to biphasic insulin aspart. Other groups were insulin detemir (n = 94), insulin aspart (n = 90), basal insulin plus insulin aspart (n = 28) and other insulin combinations (n = 19).

0.9 events/patient-year in insulin users whereas overall hypoglycaemia increased from 0.2 events/patient-year to 0.7 events/patient-year in insulin naive group. However, this hypoglycaemia incidence in insulin naive group at 24 weeks was still lower than that observed in insulin users at baseline. SADRs including major hypoglycaemic events did not occur in any of the study patients. Blood pressure decreased while overall lipid profile and quality of life improved at week 24 in the total cohort but the findings were limited by number of observations [Tables 2 and 3].
All parameters of glycaemic control improved from baseline to study end in the total cohort [Table 4].
Biphasic insulin aspart ± OGLD
Of the total cohort, 897 patients started on biphasic insulin aspart ± OGLD, of which 769 (85.7%) were insulin naïve and 128 (14.3%) were insulin users. After 24 weeks of starting or switching to biphasic insulin aspart, hypoglycaemic events decreased from 7.7 events/ patient-year to 1.1 events/patient-year in insulin user group while hypoglycaemia increased from 0.2 events/ patient-year to 0.8 events/patient-year in insulin naive group. A small increase in body weight was observed. Quality of life improved after 24 weeks [Tables 5 and 6].

Insulin detemir ± OGLD
Of the total cohort, 94 patient started on insulin detemir ± OGLD, of which 82 (87.2%) were insulin naïve and 12 (12.8%) were insulin users. After 24 weeks of starting or switching to insulin detemir, hypoglycaemic events reduced from 0.8 events/patient-year to 0.4 events/patient-year in insulin naive group, whereas hypoglycaemia increased from 1.1 events/ patient-year to 1.3 events/patient-year in insulin user group. Quality of life improved after 24 weeks [Table 11 and 12].
All parameters of glycaemic control improved from baseline to study end in those who started on or were switched to insulin detemir ± OGLDs for both insulin-naïve and insulin user groups [Table 13].

and 5 (5.6%) were insulin users. After 24 weeks of treatment starting or switching to insulin aspart, hypoglycaemic events decreased from 31.1 events/patient-year to 0.0 events/ patient-year in insulin users while hypoglycaemia increased from 0.0 events/patient-year to 0.2 events/patient-year in insulin naive group. An increase in body weight was observed for insulin user group [Table 14 and 15].
All parameters of glycaemic control improved from baseline to study end in those who started on or were switched to insulin aspart ± OGLDs for insulin naïve group while mean HbA^ and FPG values improved in the insulin user group [Table 16].
Conclusion
Our study reports improved glycaemic control and quality of life following 24 weeks of treatment with any of the insulin analogues (biphasic insulin aspart; basal + insulin

SADRs including major hypoglycaemic events or episodes did not occur in any of the study patients. Though the findings are limited by number of patients, still the trend indicates that insulin analogues can be considered effective and possess a safe profile for treating type 2 diabetes in West Bengal, India.
