Post-Transplant Diabetes Mellitus in Kidney-Transplanted Patients: Related Factors and Impact on Long-Term Outcome.

This study aimed to investigate the prevalence and determinants of glucose metabolism abnormalities and their impact on long-term clinical outcomes in kidney transplant recipients (KTxps). A retrospective analysis of 832 KTxps (2004-2020) was performed. Patients were assessed at 1 (T1), 6 (T6), and 12 (T12) months post-transplantation and clinically followed for an average of 103 ± 60 months. At T6, 484 patients underwent an oral glucose tolerance test for the diagnosis of alterations in glucose metabolism (AMG+) or post-transplant diabetes mellitus (PTDM+). The prevalence of pre-transplant diabetes was 6.2%, with 22.4% of PTDM+ within the 1st year. Patients with AMG were older and exhibited altered lipid profiles, higher body mass index, and increased inflammatory indices. Age at transplantation, lipid profile, and inflammatory status were significant determinants of PTDM. Graft loss was unaffected by glucose metabolism alterations. Survival analysis demonstrated significantly worse long-term survival for KTxps with diabetes (pre- and PTDM+, p = 0.04). In a comparison of the ND and PTDM+ groups, no significant differences in death with a functioning graft were found. The AMG+ group exhibited worse survival (p < 0.001) than AMG-, even after excluding patients with diabetes mellitus. Future randomized controlled trials are necessary to delve deeper into this subject, specifically examining the effects of new antidiabetic treatments.

Acute pericarditis with pleuropulmonary involvement, fever and elevated C-reactive protein: A systemic autoinflammatory disease? A cohort study.

OBJECTIVES: This cohort study describes a systemic phenotype of pericarditis, comparing this phenotype with other forms of pericarditis. PATIENTS AND METHODS: Patients in our center were enrolled in a prospectively maintained registry from 2019 to 2022. 412 patients with idiopathic recurrent pericarditis were analyzed. "Systemic inflammatory" subset was defined as the presence of all the following criteria: fever ≥38C°, CRP ≥2 times normal values, pleural effusion detected with any imaging techniques. The absence of any of the 3 criteria was defined as "isolated" subset. RESULTS: We found that 211 (51.2%) of 412 patients (188 female) presented the systemic subset and the variables significantly associated with this subset in univariate analysis (p<0.001) were: higher mean age: 45.5 (±SD 17.2) vs 39.9 (±SD 16.4) years, higher mean CRP values: 128.8 vs 49.9 mg/L, higher proportion of pericardiocentesis: 19% vs 1.5%, higher mean leukocyte count: 13,143.3 vs 9910.3/mm3, higher mean neutrophils number: 10,402.5 vs 6779.8 /mm3 and lower mean lymphocyte count: 1693.9 vs 2079.3 /mm3. As results the neutrophil-to-lymphocyte ratio was higher in systemic inflammatory phenotype: 6.6 vs 3.4 (p< 0.001). Anti-IL1 therapy was started more frequently in the systemic subgroup (26%) than in the isolated subset (7.5%) (p < 0.001). On multivariate analysis neutrophil count and lymphopenia were statistically associated with the systemic subset (p < 0.001). CONCLUSION: This results demonstrate the relevance of the systemic inflammatory phenotype, characterized by pleural effusions, confirming its analogy with autoinflammatory diseases, thus possibly requiring an eventual escalation of therapy to IL-1 inhibitors.
