Relationship between sodium-glucose cotransporter-2 inhibitors and muscle atrophy in patients with type 2 diabetes mellitus: a systematic review and meta-analysis

Sodium-Glucose Cotransporter-2 Inhibitors in Liver Cirrhosis: A Systematic Review of Their Role in Ascites Management, Slowing Disease Progression, and Safety

Sodium-glucose cotransporter-2 inhibitors (SGLT2Is) are widely used for type 2 diabetes mellitus (T2DM), conferring cardiovascular and renal benefits with evidence supporting their role in metabolic-associated steatotic liver disease (MASLD), the fastest rising etiology for liver cirrhosis. Our study collects and synthesizes all available data on SGLT2I use in liver cirrhosis to summarize their potential benefits and risks. We systematically reviewed the literature on SGLT2I use in adults with cirrhosis, focusing on 6 outcome domains, including ascites reduction, disease progression, hemodynamics, acute kidney injury (AKI), electrolyte abnormalities, and infection risk. We identified 16 studies: compensated (n = 5), decompensated (n = 3), and refractory ascites (n = 8). All studies of decompensated cirrhosis (n = 11) reported ascites reduction. Most studies (7 of 9) indicated SGLT2Is slowed disease progression by reducing clinical decompensation (n = 4) or improving laboratory markers (n = 3). A minority of studies revealed safety concerns with 2 of 9 studies showing evidence of hemodynamic instability and acute kidney injury (AKI), 2 out of 13 for electrolyte abnormalities, and 2 out of 5 for infection risk. Current evidence strongly supports SGLT2Is for refractory ascites management and suggests potential benefits in slowing progression across cirrhosis severities. Longer-term prospective trials in patients with non-refractory decompensated cirrhosis and real-world safety data are essential to clarify and potentially expand the role of SGLT2Is in cirrhosis management.

Effect of glucagon-like peptide-1 receptor agonists and co-agonists on body composition: Systematic review and network meta-analysis

BACKGROUND AND AIMS

While glucagon-like peptide-1 receptor agonists (GLP-1RAs) effectively reduce body weight, their impact on lean mass remains uncertain. This meta-analysis evaluated the effects of GLP-1RAs and GLP-1/GIP receptor dual agonists (GLP-1/GIP-RAs) on body composition, focusing on total weight, fat mass, and lean mass in adults with diabetes and/or overweight/obesity.

METHODS

A systematic search of Medline, Embase, and the Cochrane Library was conducted through November 12, 2024. Data were analyzed using random-effects pairwise and network meta-analyses to compare interventions with placebo or active comparators.

RESULTS

Twenty-two randomized controlled trials (2258 participants) were included. GLP-1RAs significantly reduced total body weight (MD -3.55 kg, 95 %-CI [-4.81, -2.29]), fat mass (MD -2.95 kg, 95 %-CI [-4.11, -1.79]), and lean mass (MD -0.86 kg, 95 %-CI [-1.30, -0.42]), with lean mass loss comprising approximately 25 % of the total weight loss. However, the relative lean mass, defined as percentage change from baseline, was unaffected. Liraglutide, at 3.0 mg weekly or 1.8 mg daily, was the only GLP-1RA to achieve significant weight reduction without significantly reducing lean mass. Tirzepatide (15 mg weekly) and semaglutide (2.4 mg weekly) were the most effective for weight and fat mass reduction but were among the least effective in preserving lean mass.

CONCLUSIONS

Potent GLP-1 RAs, such as tirzepatide and semaglutide, demonstrate greater overall weight loss but are associated with a significant reduction in lean mass.

Empagliflozin-induced Myopathy

Sodium/glucose co-transporter 2 (SGLT2) inhibitors are a frequently used medication for patients with type 2 diabetes, congestive heart failure (CHF), and chronic kidney disease. We present a 47-year-old patient with past medical history of type 2 diabetes and CHF who was initiated on empagliflozin and subsequently developed muscle pain and weakness. Evaluation of patient and laboratory testing confirmed drug-induced myopathy with elevated creatinine kinase (CK). Symptoms of myopathy and elevated CK resolved after holding empagliflozin. There are no current adverse effects listed with SGLT2 inhibitors including myopathy or rhabdomyolysis with the exception of other case studies. Physicians should be aware of this rare but serious side effect when initiating SGLT2 inhibitors.

Peter WL, Shubrook JH. Type 2 Diabetes and Chronic Kidney Disease: An Opportunity for Pharmacists to Improve Outcomes

Chronic kidney disease (CKD) is an important contributor to end-stage kidney disease, cardiovascular disease, and death in people with type 2 diabetes (T2D), but current evidence suggests that diagnosis and treatment are often not optimized. This review examines gaps in care for patients with CKD and how pharmacist interventions can mitigate these gaps. We conducted a PubMed search for published articles reporting on real-world CKD management practice and compared the findings with current recommendations. We find that adherence to guidelines on screening for CKD in patients with T2D is poor with particularly low rates of testing for albuminuria. When CKD is diagnosed, the prescription of recommended heart-kidney protective therapies is underutilized, possibly due to issues around treatment complexity and safety concerns. Cost and access are barriers to the prescription of newer therapies and treatment is dependent on racial, ethnic, and socioeconomic factors. Rates of nephrologist referrals for difficult cases are low in part due to limitations of information and communication between specialties. We believe that pharmacists can play a vital role in improving outcomes for patients with CKD and T2D and support the cost-effective use of healthcare resources through the provision of comprehensive medication management as part of a multidisciplinary team. The Advancing Kidney Health through Optimal Medication Management initiative supports the involvement of pharmacists across healthcare systems to ensure that comprehensive medication management can be optimally implemented.

Drug-related sarcopenia as a secondary sarcopenia

Sarcopenia has a significant impact on falls, physical function, activities of daily living, and quality of life in older adults, and its prevention and treatment are becoming increasingly important as the global population ages. In addition to primary age-related sarcopenia, activity-related sarcopenia, disease-related sarcopenia, and nutrition-related sarcopenia have been proposed as secondary sarcopenia. Polypharmacy and potentially inappropriate medication based on multiple diseases cause health problems in older patients. In some cases, drugs used for therapeutic or preventive purposes act on skeletal muscle as adverse drug reactions and induce sarcopenia. Although sarcopenia caused by these adverse drug reactions may be more common in older patients, in particular those taking many medications, drug-related sarcopenia has not yet received much attention. This review summarizes drugs that may induce sarcopenia and emphasizes the importance of drug-related sarcopenia as a secondary sarcopenia. Geriatr Gerontol Int 2024; 24: 195-203.
