Magnetic resonance enterography shows promising ability to characterize the presence of active Crohn disease as well as chronic complications (eg, differentiate between stricture due to edema vs fibrotic scarring). Magnetic resonance enterography is fast becoming a useful adjunct in the management algorithm of patients with Crohn disease.
Retransplant outcomes have improved over time, yet increased rejection and immunologic graft loss rates remain associated with pancreas retransplantation. In contrast, risk of technical failure and patient death for primary versus retransplants are similar. Therefore, pancreas retransplantation in highly selected candidates should be considered in experienced centers.
Background
Severe pulmonary hypertension (PH) has been associated with decreased post–kidney transplant survival and increased rate of long‐term cardiovascular complications. Despite a high prevalence of PH in patients with end‐stage renal disease, data on post‐transplant renal allograft survival in recipients with pre‐existing mild‐to‐moderate PH are limited.
Methods
The single‐center retrospective study cohort consisted of 192 consecutive (2008–2015) renal transplant recipients with documented pretransplantation transthoracic echocardiogram (TTE) pulmonary artery systolic pressure (PASP). Mean age was 50.9 ± 12.4 years, 36.5% were females, and 81.25% were Caucasians.
Results
Elevated PASP ≥ 37 mm Hg was present in 51 patients. Elevated PASP was more common in patients with decreased <50% left ventricular ejection fraction (13.73% vs 3.55%, P = 0.010); otherwise, there were no significant differences in baseline demographic (age, ethnicity, gender, and donor status) and clinical parameters between patients with normal and elevated PASP. Four‐year mortality (5.7%) was not significantly affected by elevated PASP. However, elevated PASP was associated with significantly decreased estimated glomerular filtration rate (eGFR) at 1 year (52.26 vs 60.13 mL/min, P = 0.019) and 2 years (51.04 vs 60.28 mL/min, P = 0.006) post‐transplant.
Conclusion
Mild and moderately elevated pre–kidney transplant PASP does not affect 4‐year post‐transplant mortality or graft loss. However, elevated pretransplant PASP is significantly associated with decreased 1 year and 2 years post‐transplant eGFR. Preoperative echocardiographic evaluation for PH may be useful in predicting the probability of short‐term renal graft and long‐term graft dysfunction in these patients.
Long-term use of steroids results in predictable secondary effects that can lead to increased morbidity and mortality. In this study, we present 10 years worth of data of early steroid withdrawal (ESW) immunosuppression consisting of mycophenolate, sirolimus, and tacrolimus. From 2003 to 2013, 563 kidney transplant recipients were weaned off steroids prior to discharge. We compared outcomes with that of our 65 historical controls maintained on steroids. We analyzed graft and patient survival and determined the incidence of steroid-related comorbidities such as hypertension, hypercholesterolemia, diabetes, coronary artery disease, and weight gain. Patients on ESW maintenance immunosuppression had improved patient and graft survival compared to controls. (HR: 0.23; P≤.011, 0.57; P=.026). Rates of biopsy-proven acute rejection were not different among both groups (HR: 1.24; P=.610). Incidence of post-transplant diabetes were reduced but not statistically significant (OR: 0.67; P=.138). Additionally, the development of hypertension (OR: 0.86, P≤.01), hypercholesterolemia (RR: 0.82; P=.027), CAD (RR: 0.43; P=.002), and >20 lbs. weight gain (RR: 0.29; P≤.01) was significantly improved over 10 years following initiation of ESW protocols. Early steroid withdrawal in renal transplant recipients results in improved patient and graft survival as well as better rates of post-transplant comorbid conditions.
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.
