Effect of ipragliflozin on liver enzymes in type 2 diabetes mellitus: a meta-analysis of randomized controlled trials.

INTRODUCTION: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is estimated to affect upto 70-80% of people with type 2 diabetes mellitus (T2DM). Although several anti-hyperglycemic drugs have been shown to be effective in such patients, there remains an unmet need for newer drugs. The objective of this meta-analysis was to analyze the effect of ipragliflozin on aspartate aminotransferase (AST), alanine transaminase (ALT), and gamma-glutamyl transpeptidase (GGT) levels in patients with T2DM. METHODS: A literature search on electronic databases was conducted to identify potential randomized clinical trials (RCT) as per predetermined study selection criteria. Mean difference (MD) was calculated using Cochrane review manager. RESULTS: Twelve studies were included in the meta-analysis, including 1349 subjects. Compared to the control group, ipragliflozin as a monotherapy showed a significant reduction in levels of ALT at week 12 (p = 0.02) and at week 24 (p = 0.007), GGT at week 12 (p < 0.00001). Ipragliflozin as an add-on therapy showed significant reduction in levels of AST at week 24 (p < 0.00001), ALT at week 12 (p = 0.002), ALT at week 24 (p < 0.00001), and GGT at week 24 (p < 0.00001). CONCLUSION: Findings suggest the beneficial effects of ipragliflozin on liver enzymes. Further large-scale RCTs are required to confirm ipragliflozin's role for liver-related conditions in T2DM.

A systematic review and meta-analysis on efficacy and safety of Ganaxolone in epilepsy.

INTRODUCTION: Ganaxolone has exhibited potential in managing seizures for epilepsy. This systematic review and meta-analysis aim to assess both the safety and efficacy of Ganaxolone for refractory epilepsy. METHODS: A thorough search of electronic databases was conducted to identify relevant randomized controlled trials involving patients with drug-resistant focal epilepsy and CDKL5 deficiency disorder. Efficacy and safety outcomes were extracted from the selected studies. Cochrane Review Manager was utilized for data synthesis and analysis, with risk ratios and mean differences calculated to evaluate the efficacy and safety profile of Ganaxolone. RESULTS: The meta-analysis included a total of five randomized controlled trials. Ganaxolone exhibited significant efficacy in reducing seizure frequency by at least 50% from baseline [RR 0.90 (95% CI: 0.83, 0.98), p = 0.02]. However, the results did not reach significance for reducing 28-day seizure frequency [Mean Difference -1.45 (95% CI: -3.39, 0.49), p = 0.14]. Ganaxolone exhibited a positive safety profile, with no statistically significant occurrence of adverse events [RR 1.30 (95% CI: 0.93, 1.83), p = 0.12] and adverse events leading to discontinuation of the study drug [RR 1.01 (95% CI: 0.42, 2.39), p = 0.99] compared to placebo. CONCLUSION: Ganaxolone presents itself as a viable therapeutic option for refractory epilepsy, showing efficacy in reducing seizure frequency and exhibited a favorable safety profile.

Longitudinal efficacy of Ertugliflozin in type 2 diabetes mellitus: a meta-analysis of randomized controlled trials.

INTRODUCTION: Ertugliflozin, a sodium-glucose cotransporter-2 inhibitor, seems to improve glycemic control in type 2 diabetes mellitus (T2DM). We aim to evaluate the efficacy of Ertugliflozin across multiple time intervals (18, 26, and 52 weeks) in T2DM patients. METHODS: A literature search was conducted on electronic databases. Data was extracted from eligible studies at both 5 mg and 15 mg doses in monotherapy and as add-on therapy. Cochrane RevMan was used to perform the meta-analysis. RESULTS: Ertugliflozin, at both 5 mg and 15 mg doses, demonstrated a significant improvement in HbA1c levels at 18 weeks 5 mg [P = 0.00001], 15 mg [P = 0.05], and at 26 weeks in monotherapy 5 mg [P = 0.006], monotherapy 15 mg [P = 0.006], 5 mg as add-on therapy [P = 0.00001], 15 mg add-on therapy [P = 0.00001] respectively. At 52 weeks, the reduction in HbA1c was significant in 15 mg add-on therapy [P = 0.0001]. Additionally, ertugliflozin as an add-on therapy also led to a significant reduction in FPG, body weight, and systolic blood pressure. CONCLUSION: Ertugliflozin showed clinical efficacy in improving glycemic control, fasting plasma glucose, body weight, and systolic blood pressure in T2DM patients over the studied time intervals compared to placebo.

Impact of tofogliflozin on hepatic outcomes: a systematic review.

PURPOSE: Studies have demonstrated a high prevalence of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM) patients. The aim was to review the effect of tofogliflozin on hepatic outcomes in T2DM patients. METHODS: A literature search in PubMed, Science Direct and Cochrane Central Register of Controlled Trials was conducted for randomised clinical trials of tofogliflozin by applying predetermined inclusion and exclusion criteria. RESULTS: A total number of four randomised clinical trials, including 226 subjects, were included in the review. There was a significant decrease in aspartate aminotransferase (AST) and alanine transaminase (ALT) levels in the tofogliflozin group as compared to the control or active comparator groups. Additionally, gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP) and magnetic resonance imaging proton density fat fraction (MRI-PDFF) levels were also significantly decreased in the tofogliflozin group. However, no significant difference was observed in levels of adiponectin. CONCLUSION: Overall, an improvement in levels of hepatic parameters was observed in T2DM patients with concurrent liver disorders. However, a large number of clinical trials are needed to prove the efficacy of tofogliflozin on hepatic outcomes in patients with T2DM.

Rotational synchronization of pinned spiral waves.

Coupled rotors can spontaneously synchronize, giving rise to a plethora of intriguing dynamics. We present here a pair of spiral waves as two synchronizing rotors, coupled by diffusion. The spirals are pinned to unexcitable obstacles, which enables us to modify their frequencies and restrain their drift. In experiments with the Belousov-Zhabotinsky reaction, we show that two counterrotating spiral rotors, pinned to circular heterogeneities, can synchronize in frequency and phase. The nature of the phase synchronization varies depending on the difference in their characteristic frequencies. We observe in-phase and out-of-phase synchronization, lag synchronization, and phase resetting across the experiments. The time required for the two spirals to synchronize is found to depend upon the relative size of their pinning obstacles and the distance separating them. This distance can also modify the phase lag of the two rotors upon synchronization. Our experimental observations are reproduced and explained further on the basis of numerical simulations of an excitable reaction-diffusion model.
