Background: This study evaluated the effect of empagliflozin on postprandial glucose (PPG) and 24-hour glucose variability in Japanese patients with type 2 diabetes mellitus (T2DM). Methods: Patients (N = 60; baseline mean [SD] HbA1c 7.91 [0.80]%; body mass index 24.3 [3.2] kg/m²) were randomized to receive empagliflozin 10 mg (n = 20), empagliflozin 25 mg (n = 19) or placebo (n = 21) once daily as monotherapy for 28 days. A meal tolerance test and continuous glucose monitoring (CGM) for 24 hours were performed at baseline and on days 1 and 28. The primary endpoint was change from baseline in area under the glucose concentration-time curve 3 hours after breakfast (AUC1-4hfor PPG) at day 28. Results: Adjusted mean (95%) differences versus placebo in changes from baseline in AUC1-4h for PPG at day 1 were -97.1 (-126.5, -67.8) mg·h/dl with empagliflozin 10 mg and -91.6 (-120.4, -62.8) mg·h/dl with empagliflozin 25 mg (both p < 0.001 versus placebo) and at day 28 were -85.5 (-126.0, -45.0) mg · h/dl with empagliflozin 10 mg and -104.9 (-144.8, -65.0) mg·h/dl with empagliflozin 25 mg (both p < 0.001 versus placebo). Adjusted mean (95% CI) differences versus placebo in change from baseline in 24-hour mean glucose (CGM) at day 1 were -20.8 (-27.0, -14.7) mg/dl with empagliflozin 10 mg and -23.9 (-30.0, -17.9) mg/dl with empagliflozin 25 mg (both p < 0.001 versus placebo) and at day 28 were -24.5 (-35.4, -13.6) mg/dl with empagliflozin 10 mg and -31.7 (-42.5,-20.9) mg/dl with empagliflozin 25 mg (both p < 0.001 versus placebo). Changes from baseline in mean amplitude of glucose excursions (MAGE; CGM) were not significantly different with either empagliflozin dose versus placebo at either timepoint. Curves of mean glucose (CGM) did not change between baseline and day 1 or 28 with placebo, but shifted downward with empagliflozin. Percentage of time with glucose =70 to <180 mg/dl increased from 52.0% at baseline to 77.0% at day 28 with empagliflozin 10 mg and from 55.0% to 81.1% with empagliflozin 25 mg, without increasing time spent with hypoglycemia. Conclusion: Empagliflozin for 28 days reduced PPG from the first day and improved daily blood glucose control in Japanese patients with T2DM. [ABSTRACT FROM AUTHOR]

Aims/hypothesis. Data now indicate that proinsulin C-peptide exerts important physiological effects and shows the characteristics of an endogenous peptide hormone. This study aimed to investigate the influence of C-peptide and fragments thereof on erythrocyte deformability and to elucidate the relevant signal transduction pathway. Methods. Blood samples from 23 patients with type 1 diabetes and 15 matched healthy controls were incubated with 6.6 nM of either human C-peptide, C-terminal hexapeptide, C-terminal pentapeptide, a middle fragment comprising residues 11-19 of C-peptide, or randomly scrambled Cpeptide. Furthermore, red blood cells from 7 patients were incubated with C-peptide, penta- and hexapeptides with/without addition of ouabain, EDTA, or pertussis toxin. Erythrocyte deformability was measured using a laser diffractoscope in the shear stress range 0.3-60 Pa. Results. Erythrocyte deformability was impaired by 18-25% in type 1 diabetic patients compared to-matched controls in the physiological shear stress range 0.6-12 Pa (P < .01-.001). C-peptide, penta- and hexapeptide all significantly improved the impaired erythrocyte deformability of type 1 diabetic patients, while the middle fragment and scrambled C-peptide had no detectable effect. Treatment of erythrocytes with ouabain or EDTA completely abolished the C-peptide, penta-and hexapeptide effects. Pertussis toxin in itself significantly increased erythrocyte deformability. Conclusion/interpretation. C-peptide and its C-terminal fragments are equally effective in improving erythrocyte deformability in type 1 diabetes. The C-terminal residues of C-peptide are causally involved in this effect. The signal transduction pathway is Ca2+-dependent and involves activation of red blood cell Na+,K+-ATPase.

Background: MSProDiscuss is a validated physician-completed tool based on a set of weighted questions that include information on multiple sclerosis (MS) relapses, symptoms, and impacts experienced by the patient within the past 6 months. The tool's traffic light system-linked output is meant as an aid for discussing the signs of MS disease progression. The tool is available online at www.msprodiscuss.com. Objectives: To report physician findings on usability and usefulness testing of the MSProDiscuss tool while discussing disease progression with patients in the real-world setting. Methods: An online qualitative survey was undertaken in 34 countries. Health care practitioners (HCPs) completed individual questionnaires (i) after using MSProDiscuss during face-to-face patient consultations and a final questionnaire (f) to capture the overall experience on the tool. The HCPs also provided general feedback and recommendations for improving the tool. Results: In total, 301 HCPs (including 23 MS nurses and 6 neurology nurse practitioners) tested the tool in 6974 patients with MS. The time taken to complete MSProDiscuss during a regular consultation was 1-4 minutes in 97% (i) to 98% (f) of the time. In 94% (i) to 97% (f ) of cases, HCPs agreed that patients were able to comprehend the questions from the tool. HCPs were willing to use the tool again in the same patient 91% (i) of the time. MSProDiscuss was useful in discussing MS symptoms and its impact on daily activities (88% i / 92% f) and cognitive function (79% both i and f) and in discussing progression in general (88% i / 90% f). While completing the final questionnaire, 95% of HCPs agreed that the questions were similar to those asked in regular consultation. MSProDiscuss was also found helpful for understanding the impact of MS symptoms on daily activities (91%) and cognitive function (80%). Overall, 92% of the HCPs would recommend MSProDiscuss to a colleague. Regarding integration of MSProDiscuss into their clinical practice, 92% of HCPs think that it is feasible and 86% are willing to integrate. Key recommendations were to allow for longitudinal follow-up, expand on cognitive assessments, and provide a patient-completed version; these are considered in the updated version of MSPro- Discuss. Conclusions: The findings from this real-world study suggest that MSProDiscuss is a usable and useful tool to facilitate physician-patient discussion on disease progression in daily clinical practice by capturing structured disease history.

Background: The alternative complement pathway plays a key role in the pathogenesis of IgA nephropathy. Iptacopan specifically binds to factor B and inhibits the alternative pathway., Methods: In this phase 3, double-blind, randomized, placebo-controlled trial, we enrolled adults with biopsy-confirmed IgA nephropathy and proteinuria with a 24-hour urinary protein-to-creatinine ratio of 1 or higher (with protein and creatinine both measured in grams) despite optimized supportive therapy. Patients were randomly assigned, in a 1:1 ratio, to receive oral iptacopan (200 mg) or placebo twice daily for 24 months while continuing to receive supportive therapy. The primary objective of this prespecified interim analysis was to assess the efficacy of iptacopan as compared with that of placebo in reducing proteinuria at month 9; the primary end point was the change from baseline in the 24-hour urinary protein-to-creatinine ratio at month 9. The proportion of patients who had a 24-hour urinary protein-to-creatinine ratio of less than 1 at month 9 without receiving rescue or alternative medication or undergoing kidney-replacement therapy (dialysis or transplantation) was a secondary end point. Safety was also assessed. The effect of iptacopan on kidney function will be assessed at the end of the 2-year double-blind treatment period., Results: The main trial population included 222 patients in the iptacopan group and 221 in the placebo group. The interim efficacy analysis included the first 250 patients who underwent randomization in the main trial population (125 patients in each group) and who remained in the trial until month 9 or discontinued the trial by month 9. Safety was assessed in all the patients in the main trial population. At month 9, the adjusted geometric mean 24-hour urinary protein-to-creatinine ratio was 38.3% (95% confidence interval, 26.0 to 48.6; two-sided P<0.001) lower with iptacopan than with placebo. The reduction in proteinuria was supported by consistent results in secondary end point analyses. There were no unexpected safety findings with iptacopan. The incidence of adverse events that occurred during the treatment period was similar in the two groups; most events were mild to moderate in severity and reversible. No increased risk of infection was observed., Conclusions: Among patients with IgA nephropathy, treatment with iptacopan resulted in a significant and clinically meaningful reduction in proteinuria as compared with placebo.

Background: To assign a course of secondary progressive multiple sclerosis (MS) (SPMS) may be difficult and the proportion of persons with SPMS varies between reports. An objective method for disease course classification may give a better estimation of the relative proportions of relapsing-remitting MS (RRMS) and SPMS and may identify situations where SPMS is under reported., Materials and Methods: Data were obtained for 61,900 MS patients from MS registries in the Czech Republic, Denmark, Germany, Sweden, and the United Kingdom (UK), including date of birth, sex, SP conversion year, visits with an Expanded Disability Status Scale (EDSS) score, MS onset and diagnosis date, relapses, and disease-modifying treatment (DMT) use. We included RRMS or SPMS patients with at least one visit between January 2017 and December 2019 if ≥ 18 years of age. We applied three objective methods: A set of SPMS clinical trial inclusion criteria ("EXPAND criteria") modified for a real-world evidence setting, a modified version of the MSBase algorithm, and a decision tree-based algorithm recently published., Results: The clinically assigned proportion of SPMS varied from 8.7% (Czechia) to 34.3% (UK). Objective classifiers estimated the proportion of SPMS from 15.1% (Germany by the EXPAND criteria) to 58.0% (UK by the decision tree method). Due to different requirements of number of EDSS scores, classifiers varied in the proportion they were able to classify; from 18% (UK by the MSBase algorithm) to 100% (the decision tree algorithm for all registries). Objectively classified SPMS patients were older, converted to SPMS later, had higher EDSS at index date and higher EDSS at conversion. More objectively classified SPMS were on DMTs compared to the clinically assigned., Conclusion: SPMS appears to be systematically underdiagnosed in MS registries. Reclassified patients were more commonly on DMTs., Competing Interests: The authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Lars Forsberg has nothing to disclose.

Many challenges exist in the precise diagnosis and clinical management of secondary progressive multiple sclerosis (SPMS) because of the lack of definitive clinical, imaging, immunologic, or pathologic criteria that demarcate the transition from relapsing-remitting MS to SPMS. This review provides an overview of the diagnostic criteria/definition and the heterogeneity associated with different SPMS patient populations; it also emphasizes the importance of available prospective/retrospective tools to identify patients with SPMS earlier in the disease course so that approved disease-modifying therapies and nonpharmacological strategies will translate into better outcomes. Delivery of such interventions necessitates an evolving patient-clinician dialog within the context of a multidisciplinary team., (Copyright © 2022 The Author(s).

Background and Objectives: A descriptive analysis of COVID-19 infection in patients with multiple sclerosis (MS) receiving fingolimod or siponimod., Methods: We reviewed the cases of COVID-19 from postmarketing or ongoing clinical trials reported to Novartis through December 27, 2020., Results: As of December 27, 2020, 283 cases had been reported in fingolimod-treated patients. The mean age was 44 years (from n = 224; range 11-69 years), and 190 were women. Of 161 cases with available information, 138 were asymptomatic (6), mild (100), or moderate (32); 50 cases required hospitalization. At the last follow-up, 140 patients were reported as recovered/recovering, condition was unchanged in 22, and deteriorated in 3 patients; 4 patients had a fatal outcome. Information was not available for 114 patients. Of the 54 cases of COVID-19 reported in siponimod-treated patients, 45 were from the postmarketing setting and 9 from an ongoing open-label clinical trial. The mean age was 54 years (from n = 45; range 31-70), and 30 were women. Of 28 cases with available information, 24 were asymptomatic (2), mild (17), or moderate (5); 9 cases required hospitalization. At the last follow-up, 27 patients were reported as recovered/recovering, condition remained unchanged for 1, and 3 patients had a fatal outcome. Information was not available for 23 patients., Discussion: Based on a review of available information, the risk of more severe COVID-19 in patients receiving fingolimod or siponimod seems to be similar to that reported in the general population and the MS population with COVID-19. However, limitations of spontaneous reporting, especially missing data, should be considered in the interpretation of these observations., (Copyright © 2021 The Author(s).

Aims: To analyse the effect of baseline glycated haemoglobin (HbA 1c ) on the reduction in HbA 1c with empagliflozin compared with sitagliptin or glimepiride in patients with type 2 diabetes., Materials and Methods: Using regression analyses of individual patient data from two Phase III studies, we compared the change in HbA 1c according to a unit change in baseline HbA 1c (the slope) with empagliflozin 10 mg or 25 mg vs sitagliptin (monotherapy) after 24 weeks, and with empagliflozin 25 mg vs glimepiride (as add-on to metformin) after 52 weeks., Results: Steeper slopes of HbA1c decline were observed with empagliflozin 10 or 25 mg vs sitagliptin monotherapy at week 24. Regression analysis showed slopes of -0.59 (95% CI -0.70, -0.47), -0.49 (95% CI -0.62, -0.37) and -0.29 (95% CI -0.42, -0.15) for empagliflozin 10 mg, empagliflozin 25 mg and sitagliptin, respectively ( P  < .001 and P  < .05 for empagliflozin 10 mg and empagliflozin 25 mg, respectively, vs sitagliptin). Similarly, a steeper slope of HbA 1c decline was observed with empagliflozin 25 mg vs glimepiride as add-on to metformin at week 52. Regression analysis showed slopes of - 0.52 (95% CI -0.59, -0.44) and -0.32 (95% CI -0.39, -0.25) for empagliflozin 25 mg and glimepiride, respectively ( P  < .001 for empagliflozin 25 mg vs glimepiride)., Conclusions: Incremental reductions in HbA 1c with increasing baseline HbA 1c are greater with empagliflozin compared with sitagliptin or glimepiride in patients with type 2 diabetes.
