Despite improvements in key parameters, the effectiveness of intravitreal ranibizumab is still compromised by poor compliance with the guidelines, especially the frequency of postinduction monitoring that is now the most important determinant of successful treatment.
Markers of epithelial‐mesenchymal transition (EMT) may identify patients at high risk of graft fibrogenesis who could benefit from early calcineurin inhibitor (CNI) withdrawal. In a randomized, open‐label, 12‐month trial, de novo kidney transplant patients received cyclosporine, enteric‐coated mycophenolate sodium (EC‐MPS) and steroids to month 3. Patients were stratified as EMT+ or EMT− based on month 3 biopsy, then randomized to start everolimus with half‐dose EC‐MPS (720 mg/day) and cyclosporine withdrawal (CNI‐free) or continue cyclosporine with standard EC‐MPS (CNI). The primary endpoint was progression of graft fibrosis (interstitial fibrosis/tubular atrophy [IF/TA] grade increase ≥1 between months 3–12) in EMT+ patients. 194 patients were randomized (96 CNI‐free, 98 CNI); 153 (69 CNI‐free, 84 CNI) were included in histological analyses. Fibrosis progression occurred in 46.2% (12/26) CNI‐free EMT+ patients versus 51.6% (16/31) CNI EMT+ patients (p = 0.68). Biopsy‐proven acute rejection (BPAR, including subclinical events) occurred in 25.0% and 5.1% of CNI‐free and CNI patients, respectively (p < 0.001). In conclusion, early CNI withdrawal with everolimus initiation does not prevent interstitial fibrosis. Using this CNI‐free protocol, in which everolimus exposure was relatively low and administered with half‐dose EC‐MPS, CNI‐free patients were overwhelmingly under‐immunosuppressed and experienced an increased risk of BPAR.
AimTo assess in real life the rate of hypoglycemia during Ramadan in patients with type 2 diabetes (T2DM) in France, according to their ongoing dual therapy of metformin-vildagliptin or metformin-sulfonylurea/glinide (IS).MethodsProspective, non-interventional study with 2 visits (within 8 weeks before and 6 weeks after the end of Ramadan 2012). Study diaries were not used to collect events or record values of glucose monitoring. One hundred and ninety-eight patients on stable oral dual therapy for ≥2 months and with glycosylated hemoglobin (HbA1c) ≤8.0% were recruited by 62 centers: 83 in the IS cohort and 115 in the vildagliptin cohort.ResultsApproximately 90% of patients were from Maghreb. The two cohorts were well balanced: 60% men, mean age 59 years, BMI 28 kg/m2, metformin dose ~2,000 mg/day, and HbA1c 7.2%. Distinct therapeutic management was planned in view of Ramadan with drug-adaptation intended in 61.4% of IS and 18.3% of vildagliptin patients. Hypoglycemia was reported in 37% of IS and 34% of vildagliptin patients; episodes declared as confirmed in 30.8% and 23.5%, respectively, and episodes documented as adverse event (AE) in 17.9% (22 episodes) and 7.5% (13 episodes), respectively (P = 0.025). Severe episodes were reported in 3.9% of IS and 1.7% of vildagliptin patients. 10.4% of IS and 2.6% of vildagliptin patients reported severe episodes and/or unscheduled medical visits due to hypoglycemia (P = 0.029). Glycemic control remained stable in both cohorts. Compliance with fasting was high, as well as adherence to drug with ≥5 missed-dose for 15.4% of IS and 8.5% of vildagliptin patients.ConclusionAlthough the overall frequency of malaise suggestive of hypoglycemia was high, which would be expected with prolonged fasting in a well-controlled T2DM population during hot summer days, the incidence of more severe and better-documented episodes (AE, severe event, event leading to unscheduled medical visit) were much lower, with consistently less events with vildagliptin therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
