Allergic reaction to insulin is mediated by several mechanisms; differences in amino acid sequence of animal and human insulin, altered tertiary structure of insulin and the presence of non-insulin protein contaminants or pharmaceutical additives. Anaphylactic reactions to insulin only occur in 0.1 to 2% of patients who stopped insulin therapy and have then resumed treatment. We report a diabetic patient who suffered severe anaphylactic reactions to human recombinant insulin, successfully treated by desensitization. A 19-year-old man with type 1 diabetes receiving Insulatard HM(R) developed generalized urticaria and angioedema with progression to dyspnea, dizziness and syncope. Skin prick test to all kinds of human recombinant insulin products revealed immediate type hypersensitivity and the titer of insulin IgE was increased in serum. The desensitization trial with Velosulin HM(R) using modified desensitization method was performed. Six months after the desensitization he was taking Velosulin HM(R) as well as Insulatard HM(R) without any evidence of systemic allergic reactions.

Background and Objective: Anthocyanins are associated with aging and longevity. However, the mechanism involving the pure anthocyanin compounds in aging remains elusive. To investigate the possible mechanism of action of the different anthocyanin compounds towards aging-associated enzymes, the lead-likeness, binding affinity, and binding interactions were evaluated. Methodology: The different anthocyanin compounds such as cyanidin, delphinidin, malvidin, pelargonidin, peonidin, and petunidin were assessed for lead-likeness following the criteria of Lipinski's rule of five (Ro5). These same compounds were virtually docked to different aging-related enzymes involved in MAPK, AMPK, and insulin signaling pathways. The top binding anthocyanins for each enzyme were visualized and compared to the enzyme inhibitors. Results: The different anthocyanin compounds abide with Ro5 denoting its potential as a lead compound. For each enzyme, there were different top-binding anthocyanins. The crystal structures of the docked anthocyanins reveal that there were different substructures involved during the non-covalent interaction. Some substructures, particularly the hydroxy groups, have different roles during the H-bond formation. These findings suggest that the various anthocyanin compounds may have a distinct mechanism of action towards a specific enzyme. Conclusion Taken together, these results suggest that the anthocyanin compounds may have varying effects in aging enzymes, which may be due to the differences in their substructures. Nonetheless, further investigations are needed to understand these findings using cells and animal models.

Background: Diabetes Mellitus (DM), characterised by chronic hyperglycaemia, exposes patients to acute and chronic complications, such as hypoglycaemia and vascular complications, respectively. The latter is associated with the degree of glycaemic control. Glycated haemoglobin (HbA1c) indicates long-term glycaemic control of the preceding 2-3 months. The practice of self-monitoring blood glucose (SMBG) is essential for insulin-treated diabetic patients to achieve optimum glycaemic control and prevent hypoglycaemia. Aim: The study aimed to determine the SMBG practice and frequency and its association with HbA1c and factors in insulin-treated diabetic patients. Methods: This was a cross-sectional study of insulin-treated diabetic patients attending follow-up at the diabetic clinic of Hospital Serdang from April 2015 to August 2015. Consented eligible patients completed validated selfadministered questionnaires. Patients’ HbA1c results were obtained from the hospital information system. Results: Ninetyone of 137 (66%) patients practiced SMBG and 46 (34%) did not. Although 82% had seen diabetic nurses, 54% of patients did not alter their treatment accordingly. Neither the practice nor the frequency of SMBG was significantly associated with differences in HbA1c levels (p=0.334 and p=0.116 respectively). Ethnicity and household income significantly affected SMBG practice. The presence and frequency of hypoglycaemia significantly increased the likelihood of SMBG practice (p<0.001) and frequency (p<0.001). Conclusions: The prevalence of SMBG practice in diabetic patients on insulin was 66%. However, SMBG was not followed by proper treatment alteration in 54% of patients. There was no association between SMBG practice and frequency with good glycaemic control. Hypoglycaemia significantly affected the practice and frequency of SMBG.

Objective: To provide real-world data on hypoglycaemia incidence in patients with type 1 (T1D) or type 2 diabetes (T2D) from the Southeast Asian cohort of the International Operations Hypoglycaemia Assessment Tool (IO HAT) study. Methodology: IO HAT was a non-interventional, multicentre, 6-month retrospective and 4-week prospective study of hypoglycaemic events among insulin-treated adults with T1D or T2D, including four countries in Southeast Asia (Singapore, Philippines, Indonesia, and Bangladesh). Data were collected using a two-part self-assessment questionnaire (SAQ1 for retrospective and SAQ2 for prospective). The primary endpoint was the percentage of patients experiencing at least one hypoglycaemic event during the 4-week prospective observational period (ClinicalTrials.gov Identifier: NCT02306681). Results: A total of 2594 patients completed SAQ1. Nearly all patients reported experiencing any hypoglycaemic event in the 4-week prospective period (T1D, 100%; T2D, 97.3%), with all patients reporting higher rates in the prospective versus retrospective period. Severe hypoglycaemia was also reported higher prospectively (57.2% and 76.9%) than retrospectively (33.9% and 12.2%) in both T1D and T2D, respectively. Nocturnal hypoglycaemia was reported higher retrospectively than prospectively. Conclusion Incidence of any and severe hypoglycaemia in the Southeast Asian cohort of IO HAT was higher prospectively versus retrospectively, suggesting hypoglycaemia has previously been under-reported in this region.

OBJECTIVE: To evaluate the safety, effectiveness and health-related quality of life (HRQoL) parameters of A1chieve study participants in the Philippine cohort, who were treated with BIAsp 30.
METHODOLOGY: A1chieve is a non-interventional, six-month, observational study of 66,726 people with type 2 diabetes mellitus (T2DM), including both insulin users and non-insulin users, started on insulin detemir, insulin aspart, or BIAsp 30 in 28 countries across four continents. The present study evaluates the safety, effectiveness and HRQoL in 1,252 subjects from the Philippine cohort of the A1chieve study who were treated with BIAsp 30.
RESULTS: At baseline, the mean age, duration of diabetes and mean BMI were found to be 55.5±11.7 years, 7.2 ± 5.6 years and 25.4 ± 5.3 kg/m2, respectively. Seventy-eight percent (78%) of subjects were insulin naïve and 22% were prior insulin users. At baseline, glycemic control was poor (HbA1c = 9.9%) in the entire cohort. Overall there was a 2.7% reduction in mean HbA1c and 44.2% subjects achieved the HbA1c target of <7.0%, after 24 weeks of therapy with BIAsp 30. There were significant reductions in total cholesterol, LDL-cholesterol, triglycerides and systolic blood pressure after 24 weeks of therapy with BIAsp 30. There was no increase in the incidence of hypoglycemia among insulin-naïve subjects, while there was a marked reduction in hypoglycemia (4.93 to 2.53 events/person-year) among prior insulin users at 24 weeks.
CONCLUSION: BIAsp 30 is safe and efficacious for initiating and intensifying insulin therapy for Filipino T2DM patients.
