Glucose monitoring has evolved from self-monitoring of blood glucose to glycated hemoglobin, and the latest continuous glucose monitoring (CGM). A key challenge to adoption of CGM for management of diabetes in Asia is the lack of regional CGM recommendations. Hence, thirteen diabetes-specialists from eight Asia-Pacific (APAC) countries/regions convened to formulate evidence-based, APAC-specific CGM recommendations for individuals with diabetes. We defined CGM metrics/targets and developed 13 guiding-statements on use of CGM in: (1) people with diabetes on intensive insulin therapy, and (2) people with type 2 diabetes on basal insulin with/without glucose lowering drugs. Continual use of CGM is recommended in individuals with diabetes on intensive insulin therapy and suboptimal glycemic control, or at high risk of problematic hypoglycemia. Continual/intermittent CGM may also be considered in individuals with type 2 diabetes on basal insulin regimen and with suboptimal glycemic control. In this paper, we provided guidance for optimizing CGM in special populations/situations, including elderly, pregnancy, Ramadan-fasting, newly diagnosed type 1 diabetes, and comorbid renal disease. Statements on remote CGM, and stepwise interpretation of CGM data were also developed. Two Delphi surveys were conducted to rate the agreement on statements. The current APAC-specific CGM recommendations provide useful guidance for optimizing use of CGM in the region.

The global burden of diabetes is estimated to escalate from about 171 million in 2000 to 366 million people in 2030. The routine of diabetes treatment by injection of insulin incurs pain and has been one major factor negating the quality of life of diabetic patients. The possibility of administering insulin via alternative routes such as oral and nasal pathways has been investigated over the years, but with insulin experiencing risks of enzymatic degradation and poor transmucosal absorption. This leads to the rising needs to develop new formulation strategies emphasizing on the assembly of insulin and excipients into a physical structure to maintain the stability and increase the bioavailability of insulin. Chitosan and its derivatives or salts have been widely investigated as functional excipients of delivering insulin via oral, nasal and transdermal routes. The overview of various recent patented strategies on non-injection insulin delivery denotes the significance of chitosan for its mucoadhesive and able to protect the insulin from enzymatic degradation, prolong the retention time of insulin, as well as, open the inter-epithelial tight junction to facilitate systemic insulin transport. The chitosan can be employed to strengthen the physicochemical stability of insulin and multi-particulate matrix. The introduction of chitosan coat or co-formulation of chitosan with cationic gelatin or electrolytes which provide solidified or partially crosslinked structures retain and/or enhance the positive charges of dosage form necessary to induce mucoadhesiveness. The chitosan is modifiable chemically to produce water-soluble low molecular weight polymer which renders insulin able to be processed under mild conditions, and sulphated chitosan which markedly opens the paracellular channels for insulin transport. Combination of chitosan and fatty acid as hydrophobic nanoparticles promotes the insulin absorption via lymphoid tissue. Attainment of optimized formulations with higher levels of pharmacological bioavailability is deemed possible in future through targeted delivery of insulin using chitosan with specific adhesiveness to the intended absorption mucosa.

Adding biphasic insulin aspart 30 once or twice daily is more efficacious than optimizing oral antidiabetic treatment in patients with type 2 diabetes

Bebakar WM, Chow CC, Kadir KA, Suwanwalaikorn S, Vaz JA, Bech OM, et al.

Diabetes Obes Metab, 2007 Sep;9(5):724-32.
PMID: 17593237 DOI: 10.1111/j.1463-1326.2007.00743.x

Aim: To evaluate the efficacy and safety of adding biphasic insulin aspart 30 (BIAsp30; NovoMix 30) to existing oral antidiabetic agents (OADs) vs. optimizing OADs in a subgroup of Western Pacific patients with type 2 diabetes inadequately controlled on oral monotherapy or oral combination therapy.

Methods: This 26-week, multi-centre, open-labelled, randomized, two-arm parallel trial consisted of a 2-week screening period, followed by 24 weeks of treatment. Subjects randomized to BIAsp30 treatment (n = 129) received BIAsp30 once daily (o.d.) at dinnertime between Week 2 and Week 14, and those not reaching treatment targets were switched to twice daily (b.i.d.) BIAsp30 at Week 14 (n = 50). Subjects randomized to the OAD-only arm (n = 63) continued with their previous OAD treatment and, in an attempt to reach treatment goals, the dose was optimized (but OAD unchanged) in accordance to local treatment practice and labelling.

Results: Significantly greater reductions in HbA(1c) over Weeks 0-13 with BIAsp30 (o.d.) vs. OAD-only treatment (1.16 vs. 0.58%; p < 0.001), and over Weeks 0-26, with BIAsp30 (o.d.) and BIAsp30 (b.i.d.) treatments vs. OAD-only treatment (1.24 vs. 1.34 vs. 0.67%; p < 0.01). Hypoglycaemic episodes were reported in 54% of the patients in BIAsp30 (o.d. and b.i.d. pooled) and 30% of the patients in OAD-only group. All episodes were minor or symptomatic, except for one in each treatment group, which was major.

Conclusions: Initiating BIAsp30 treatment is a safe and more effective way to improve glycaemic control in Western Pacific patients with type 2 diabetes inadequately controlled with oral monotherapy or oral combination therapy compared with optimizing oral combination therapy alone. In patients not reaching treatment target on BIAsp30 (o.d.), treatment with BIAsp30 (b.i.d.) should be considered.

Metformin: A Salutary Candidate for Colorectal Cancer Treatment in Patients with Diabetes

Samuel VP, Dahiya R, Singh Y, Gupta G, Sah SK, Gubbiyappa SK, et al.

J Environ Pathol Toxicol Oncol, 2019;38(2):133-141.

The current study is a review of the literature on patients with diabetes who are diagnosed with colorectal cancer (CRC), encompassing recent research on CRC and the molecular level changes occurring in these patients on the basis of varying environmental as well as non-environmental factors. It has been noted that nearly 50% of all patients undergo the systemic treatment module; however, most of them exhibit drug resistance. In addition, targeted gene therapy has also been used in treatment but has been found to be effective only in patients with a specified molecular profile (or else this might lead to an increased risk of developing resistant mutations). This has led to increasing interest among researchers in finding innovative treatment options. Metformin, a biguanide, has been widely used in treating diabetes. The drug has been reportedly used in cases of hypothesis-generating retrospective population studies of diabetic patients showing reduced incidence of cancer. Metformin helps in reduction of excess insulin levels that possess various effects on cell signaling and metabolism. Nonetheless, there is need for an in-depth study on its molecular mechanism to fill any existing research gaps.

Fulltext Review of insulin-associated hypoglycemia and its impact on the management of diabetes in Southeast Asian countries

Goh SY, Hussein Z, Rudijanto A

J Diabetes Investig, 2017 Sep;8(5):635-645.
PMID: 28236664 DOI: 10.1111/jdi.12647

Although the incidence of diabetes is rising in Southeast Asia, there is limited information regarding the incidence and manifestation of insulin-associated hypoglycemia. The aim of the present review was to discuss what is currently known regarding insulin-associated hypoglycemia in Southeast Asia, including its known incidence and impact in the region, and how the Southeast Asian population with diabetes differs from other populations. We found a paucity of data regarding the incidence of hypoglycemia in Southeast Asia, which has contributed to the adoption of Western guidelines. This might not be appropriate, as Southeast Asians have a range of etiological, educational and cultural differences from Western populations with diabetes that might place them at greater risk of hypoglycemia if not managed optimally. For example, Southeast Asians with type 2 diabetes tend to be younger, with lower body mass indexes than their Western counterparts, and the management of type 2 diabetes with premixed insulin preparations is more common in Southeast Asia. Both of these factors might result in higher rates of hypoglycemia. In addition, Southeast Asians are often poorly educated about hypoglycemia and its management, including during Ramadan fasting. We conclude there is a need for more information about Southeast Asian populations with diabetes to assist with the construction of more appropriate national and regional guidelines for the management of hypoglycemia, more closely aligned to patient demographics, behaviors and treatment practices. Such bespoke guidelines might result in a greater degree of implementation and adherence within clinical practice in Southeast Asian nations.

Early transition from insulin to sulfonylureas in neonatal diabetes and follow-up: Experience from China

Li X, Xu A, Sheng H, Ting TH, Mao X, Huang X, et al.

Pediatr Diabetes, 2018 03;19(2):251-258.
PMID: 28791793 DOI: 10.1111/pedi.12560

BACKGROUND: Sulfonylurea therapy can improve glycemic control and ameliorate neurodevelopmental outcomes in patients suffering from neonatal diabetes mellitus (NDM) with KCNJ11 or ABCC8 mutations. As genetic testing results are often delayed, it remains controversial whether sulfonylurea treatment should be attempted immediately at diagnosis or doctors should await genetic confirmation.
OBJECTIVE: This study aimed to investigate the effectiveness and safety of sulfonylurea therapy in Chinese NDM patients during infancy before genetic testing results were available.
METHODS: The medical records of NDM patients with their follow-up details were reviewed and molecular genetic analysis was performed. Sulfonylurea transfer regimens were applied in patients diagnosed after May 2010, and glycemic status and side effects were evaluated in each patient.
RESULTS: There were 23 NDM patients from 22 unrelated families, 10 had KCNJ11 mutations, 3 harbored ABCC8 mutations, 1 had INS mutations, 4 had chromosome 6q24 abnormalities, 1 had a deletion at chromosome 1p36.23p36.12, and 4 had no genetic abnormality identified. Sixteen NDM infants were treated with glyburide at an average age of 49 days (range 14-120 days) before genetic confirmation. A total of 11 of 16 (69%) were able to successfully switch to glyburide with a more stable glucose profile. The responsive glyburide dose was 0.51 ± 0.16 mg/kg/d (0.3-0.8 mg/kg/d), while the maintenance dose was 0.30 ± 0.07 mg/kg/d (0.2-0.4 mg/kg/d). No serious adverse events were reported.
CONCLUSIONS: Molecular genetic diagnosis is recommended in all patients with NDM. However, if genetic testing results are delayed, sulfonylurea therapy should be considered before such results are received, even in infants with newly diagnosed NDM.
