Nonarteritic Anterior Ischemic Optic Neuropathy and Semaglutide: What is This All About?

Nonarteritic anterior ischemic optic neuropathy (NAION) was first documented by a French physician Jean-Pierre Saint-Yves in 1817 (19th century). The clinical description of NAION was not known until 1935 when C. Miller Fischer thoroughly described it. Briefly, NAION is a rare (2.5-11.8 per 1,00,000 cases in men above 50 years) but serious condition that causes sudden painless loss of vision due to ischemia of the optic nerve.1 It is more common in Caucasians compared with Asians and is associated with various risk factors such as hypertension, type 2 diabetes (T2D), smoking, hyperlipidemia, obesity, obstructive sleep apnea, small optic nerve cup ("disk at risk"), optic nerve drusen, and certain drugs, especially phosphodiesterase type 5 inhibitors (PDE-5I), amiodarone, and cabergoline.2 Although the clinical development programs and real-world studies of semaglutide [a glucagon-like peptide-1 receptor agonist (GLP-1RA) approved for the treatment of T2D and obesity] did not report any significant increase in the risk of NAION, a recent retrospective cohort study suggested a possible link between NAION and semaglutide.3 This editorial briefly summarizes the current knowledge about NAION and its relation to metabolic disorders, cardiovascular, and antidiabetes drugs and puts a perspective concerning semaglutide.

Responsible Use of Oral Corticosteroids in People with Comorbid Diabetes: An Expert Consensus.

Globally, diabetes mellitus (DM) is a substantial contributor to morbidity and mortality. Comorbidities and intercurrent illnesses in people with diabetes may necessitate the use of steroids. Acute as well as chronic use of steroids contributes substantially to the development of various complications. Despite this, there are no standard guidelines or consensus to provide a unified approach for the rational use of steroids in people with diabetes. Also, there is scant harmonization among clinicians with the use of different steroids in routine practice. To address the inconsistencies in this clinical arena, the consensus working group (CWG) formulated a unified consensus for steroid use in people with diabetes. In people with diabetes, the use of steroids causes hyperglycemia and may precipitate diabetic ketoacidosis (DKA). An increase in weight is directly related to the dose and duration of the steroid therapy. Steroid-related alterations in hyperglycemia, dyslipidemia, and hypertension (HTN) add to the increased risk of cardiovascular (CV) disease. The risk of complications such as infections, osteoporosis, myopathy, acne, cataracts, and glaucoma may increase with the use of steroids. Appropriate and timely monitoring of these complications is necessary for early detection and treatment of such complications. Given the systemic effects of various antihyperglycemic drugs, there is a possibility of aggravating or diminishing the specific complications. Preference to a safer steroid is required matching the steroid dose equivalence and individualizing patient management. In conclusion, short-, intermediate-, or long-term use of steroids in people with diabetes demands their rational use and holistic approach to identify, monitor, and treat the complications induced or aggravated by the steroids.

Fixed-Dose Combination of Canagliflozin and Metformin as an Adjunct to Diet and Exercise in Indian Adults with Type 2 Diabetes Mellitus: Results from a Multicentric, Open-Label, Single-Arm, Phase IV Study.

BACKGROUND: Canagliflozin and metformin fixed-dose combination (CANA/MET FDC), an approved treatment for type 2 diabetes mellitus (T2DM) in India, effectively lowers glycated hemoglobin (HbA1c), promotes weight loss, and improves patient adherence. As a regulatory requirement, we aimed to evaluate the safety and efficacy of CANA/MET FDC in Indian patients with T2DM. RESEARCH DESIGN AND METHODS: This prospective, multicenter, open-label, single-arm, phase IV study included Indian patients with T2DM (aged 18-65 years) inadequately controlled on diet and exercise. Patients received CANA/MET (50/500 and 50/1000 mg) immediate-release (IR) FDC twice daily for 24 weeks. The primary endpoint was safety assessment, including adverse events (AEs) and serious AEs (SAEs). The secondary endpoint included a change in HbA1c from baseline to weeks 12 and 24. Descriptive statistics were used for all continuous safety variables and efficacy parameters. RESULTS: Of the 310 patients screened, 276 were enrolled. 114/274 (41.6%) patients had ≥1 treatment-emergent AE [treatment-emergent AEs (TEAEs), among which 29 (10.6%) were related to study intervention]. The most common TEAEs were dyslipidemia (4.7%), pyrexia (4.7%), genital infections (3.3%), hypoglycemia (3.3%), and urinary tract infections (2.6%). Three (1.1%) patients had serious TEAEs, and all cases were resolved. No deaths were reported. The mean change in HbA1c from baseline was -0.92 and -0.93% at weeks 12 and 24, respectively. CONCLUSION: The study demonstrates the safety and efficacy of CANA/MET FDC in Indian patients with T2DM, presenting a safe therapeutic option for diabetes management in India.

Fortifying Micronutrient Supplementation in India: Indian Expert consensus.

Micronutrients play a key role in human health, being involved in energy metabolism, immunity, cellular functioning, growth, and development. Deficiencies in micronutrients occur in individuals of all ages due to several factors, including inadequate diets, disease states, and overweight/obesity. Guidelines from the Indian Council of Medical Research (ICMR) National Institute of Nutrition (NIN) Expert Group on Nutrient Requirements for Indians (2023) have specified the Recommended Dietary Allowances (RDA) for macronutrients and micronutrients. In addition, a healthy diet is crucial for overall health and should be the first step toward addressing micronutrient deficiencies. When diet is inadequate, micronutrient supplements can be provided to compensate. An expert panel of Indian doctors was convened to develop a pathway toward micronutrient supplementation among the Indian population. This Consensus Statement recognizes that different populations have varying needs for specific micronutrients, and ensuring adequate intake of such micronutrients can improve health outcomes. The panel provided recommendations for dietary practices and micronutrient supplementation when diet is inadequate. Addressing micronutrient deficiencies at the primary care level can prevent chronic deficiencies and their consequences. This Consensus Statement can serve as a primer for physicians to monitor and address deficiencies and thus help individuals maintain their health.

SGLT2i as a First-line Antihyperglycemic in the Management of Type 2 Diabetes in the Context of Indians: A Systematic Review and Consensus.

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been used for almost a decade and have proven to be effective not only in managing Type 2 diabetes (T2D), but their cardio and renal protective features make them very useful in managing patients with risk of multiple comorbidities. This systematic review was undertaken by the authors because there is no evidence currently available in India that has studied the suitability of SGLT2i as a first-line agent in patients newly diagnosed with T2D in India. MATERIALS AND METHODS: First, literature was searched to identify features that are considered important when deciding on a first-line agent for managing T2D. A total of 5 broad topics were identified-glycemic control, extra glycemic effects, antihyperglycemic combination therapy, safety, and cost-effectiveness. These domains had further subheadings, and a total of 16 domains were identified. Metformin is the drug of choice as a first-line agent in such situations and has been considered the gold standard for evaluating the effects of SGLT2i across these domains. A systematic literature review on each domain was conducted to compare SGLT2i with the gold standard in Indian patients newly diagnosed with T2D. Evidence was graded (levels of evidence (LoE)-A, B, and C), and recommendations (class of recommendation (CoR)-I, II, and III) were classified by the expert group as defined in the methodology. RESULTS: According to the systematic reviews conducted, 11 domains had Level A evidence, 2 domains (impact on lipids and gut microbiome) had Level B, and 3 domains had Level C (ß-cell function, renal protection, and glycemic variability) evidence. Based on evidence and expert opinion, the authors recommend SGLT2i as a first-line agent for managing newly diagnosed patients with T2D with a Class I recommendation for 13 domains and Class II for the remaining 3 (impact on lipids, gut microbiome, and ß-cell function). Although a poorer level of evidence (Level C) was available for the glycemic variability domain, the authors still reported this as Class I recommendations according to their expert opinion and consensus. CONCLUSION: This article advocates adopting SGLT2 inhibitors as the primary treatment choice for treating patients with newly diagnosed T2D in India.
