RESUMEN
OBJECTIVES: Studies suggest that transplant patients are at a higher risk of developing chronic rhinosinusitis (CRS). However, there is a dearth of studies describing the factors that may be linked to the development of CRS in this population. Our objective is to identify the risk factors associated with the development of CRS in transplant recipients. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary care center. METHODS: This cohort included 3347 transplant recipients seen between 2017 and 2022. Of these, 2128 patients met the inclusion criteria and were grouped according to whether they were diagnosed with CRS during the post-transplant period. The analysis included both univariate and multivariate analysis to ascertain the odds ratio (OR) and predictive factors. RESULTS: Of the 2128 patients, 649/2128 (30.4%) had CRS. CRS patients had an increased prevalence of previous endoscopic sinus surgery, allergic rhinitis, and recurrent acute rhinosinusitis in the pre-transplant period compared to the non-CRS group. According to the multivariate analysis, patients with primary immunodeficiency and additional transplant were 1.9 and 3.1 times more likely to develop CRS during the posttransplant period (95% CI: 1.3-2.6, p < .0001), (95% CI: 1.3 -7.3, p = .01), respectively. Sirolimus use was also associated with the development of CRS (OR = 1.4, 95% CI: 1.1-1.9, p = .01). CONCLUSION: This study is the largest cohort aimed at determining the predictive factors associated with the development of CRS. Patients with pretransplant rhinologic conditions, hematologic deficiencies, and the utilization of specific immunosuppressants were found to have a higher likelihood of developing CRS following transplantation.
RESUMEN
Autoimmune hepatitis is an immune-mediated inflammatory condition of the liver of undetermined cause that affects both sexes, all ages, races, and ethnicities. Its clinical presentation can be very broad, from having an asymptomatic and silent course to presenting as acute hepatitis, cirrhosis, and acute liver failure potentially requiring liver transplantation. The diagnosis is based on histological abnormalities (interface hepatitis), characteristic clinical and laboratory findings (increased aspartate aminotransferase, alanine aminotransferase, and serum IgG concentration), and the presence of one or more characteristic autoantibodies. The large heterogeneity of these clinical, biochemical, and histological findings can sometimes make a timely and proper diagnosis a difficult task. Treatment seeks to achieve remission of the disease and prevent further progression of liver disease. First-line therapy includes high-dose corticosteroids, which are later tapered to decrease side effects, and azathioprine. In the presence of azathioprine intolerance or a poor response to the standard of care, second-line therapy needs to be considered, including mycophenolate mofetil. AIH remains a diagnostic and therapeutic challenge, and a further understanding of the pathophysiological pathways of the disease and the implementation of randomized controlled trials are needed.
RESUMEN
With donation after circulatory death (DCD) liver transplantation (LT), the goal of the recipient implantation procedure is to minimize surgical complexity to avoid a tenuous environment for an already marginal graft. The presence of portal vein thrombosis (PVT) at the time of LT adds surgical complexity, yet' to date, no studies have investigated the utilization of DCD liver grafts for patients with PVT. Methods: All DCD LT performed at Mayo Clinic-Florida, Mayo Clinic-Arizona, and Mayo Clinic-Rochester from 2006 to 2020 were reviewed (N = 771). Patients with PVT at the time of transplant were graded using Yerdel classification. A 1:3 propensity match between patients with PVT and those without PVT was performed. Results: A total of 91 (11.8%) patients with PVT undergoing DCD LT were identified. Grade I PVT was present in 62.6% of patients, grade II PVT in 27.5%, grade III in 8.8%, and grade 4 in 1.1%. At the time of LT, thromboendovenectomy was performed in 89 cases (97.8%). There was no difference in the rates of early allograft dysfunction (43.2% versus 52.4%; P = 0.13) or primary nonfunction (1.1% versus 1.1%; P = 0.41) between the DCD PVT and DCD without PVT groups, respectively. The rate of ischemic cholangiopathy was not significantly different between the DCD PVT (11.0%) and DCD without PVT groups (10.6%; P = 0.92). Graft (P = 0.58) and patient survival (P = 0.08) were similar between the 2 groups. Graft survival at 1-, 3-, and 5-y was 89.9%, 84.5%, and 79.3% in the DCD PVT group. Conclusions: In appropriately selected recipients with grades I-II PVT, DCD liver grafts can be utilized safely with excellent outcomes.
