RESUMO
Membranous nephropathy (MN) is a leading cause of kidney failure worldwide and frequently recurs after transplant. Available data originated from small retrospective cohort studies or registry analyses; therefore, uncertainties remain on risk factors for MN recurrence and response to therapy. Within the Post-Transplant Glomerular Disease Consortium, we conducted a retrospective multicenter cohort study examining the MN recurrence rate, risk factors, and response to treatment. This study screened 22,921 patients across 3 continents and included 194 patients who underwent a kidney transplant due to biopsy-proven MN. The cumulative incidence of MN recurrence was 31% at 10 years posttransplant. Patients with a faster progression toward end-stage kidney disease were at higher risk of developing recurrent MN (hazard ratio [HR], 0.55 per decade; 95% confidence interval [CI], 0.35-0.88). Moreover, elevated pretransplant levels of anti-phospholipase A2 receptor (PLA2R) antibodies were strongly associated with recurrence (HR, 18.58; 95% CI, 5.37-64.27). Patients receiving rituximab for MN recurrence had a higher likelihood of achieving remission than patients receiving renin-angiotensin-aldosterone system inhibition alone. In sum, MN recurs in one-third of patients posttransplant, and measurement of serum anti-PLA2R antibody levels shortly before transplant could aid in risk-stratifying patients for MN recurrence. Moreover, patients receiving rituximab had a higher rate of treatment response.

INTRODUCTION: Facial function correlates with quality of life in facial palsy. Previous studies have examined a linear relationship; based on clinical experience, we hypothesize a curved regression (i.e. quadratic or cubic) will be more fitting to show the correlation between quality of life and facial function. METHODS: We compared the fit of a linear regression model between Sunnybrook scores (facial function) and FaCE and FDI scores (quality of life) to a quadratic and cubic regression model in 125 patients cross-sectionally. RESULTS: A total of 125 patients were included, 53.6% female with a mean (standard deviation) age of 56.6 (16.7) and a median (interquartile range) duration of palsy of 6.6 (1.5; 18.3) years. The quadratic regression proved a significant improvement over a linear regression analysis in the model using the FaCE total score (linear R2 =.346, quadratic R2 = .378, p = .033) and the FDI physical score (linear R2 = .245, quadratic R2 =.276, p = .034). The cubic regression analysis was no significant improvement over a quadratic regression. DISCUSSION: The relationship between facial function and quality of life in facial palsy is not linear meaning that there is a lot of variation in QoL in cases with severe and moderate facial impairment. This is most applicable to patients suffering from post-paralysis synkinesis, proving the highly individually experienced burden of synkinesis. As the relationship is not linear it should not be included as such in future research studies.

Background: In solid organ transplant recipients (SOTRs), studies investigating post-acute sequelae of SARS-CoV-2 infection (PASC) are limited, and risk factors for their development require further investigation. Methods: In this cross-sectional study, we evaluated PASC symptoms among SOTRs followed at our institutions who had COVID-19 during the Omicron period from December 28, 2021, to November 4, 2022. Participants were surveyed using a newly published PASC score containing 13 symptoms experienced for ≥30 d. PASC was defined as a score of ≥12. Results: Of 299 SOTRs invited, 93 completed the survey and were analyzed. The mean age was 58 y and 43% were women. Forty-six individuals (49%) reported experiencing ≥1 PASC symptom for ≥30 d, of whom 13 (14%) met the PASC definition. Multivariable analysis showed that female sex (adjusted odds ratio [aOR] = 0.32; 95% confidence interval [CI], 0.12-0.83), years from transplantation (aOR = 0.90 per additional year; 95% CI, 0.81-0.99), and tixagevimab-cilgavimab preexposure prophylaxis (aOR = 0.33; 95% CI, 0.12-0.84) were associated with significantly lower odds of developing ≥1 PASC symptom. Conclusions: PASC symptoms are common in SOTRs infected during the Omicron period. PASC symptoms are less frequent in those with a longer time since transplant and in those who received tixagevimab-cilgavimab. New SARS-CoV-2 prevention and treatment strategies should also evaluate PASC symptoms as outcomes.
RESUMO
Introduction: Cardiovascular disease is a significant cause of mortality after kidney transplantation. Whether pre-transplant screening for coronary artery disease (CAD) in asymptomatic kidney transplant candidates (KTCs) is beneficial is unclear. Methods: We conducted a retrospective cohort study evaluating post-transplant cardiovascular events in 192 high-risk KTCs who underwent pre-transplant CAD evaluation. The study aimed to identify risk factors associated with finding severe CAD on pre-transplant angiography, and to assess the relationship between screening strategies and post-transplant cardiovascular events. Results: At five years post-transplant, cardiovascular events occurred in 23.9% of subjects. Prior CAD history and left ventricular ejection fraction (LVEF) < 50% were associated with higher odds of finding severe CAD on pre-transplant angiography. Severe CAD on angiography was associated with a higher risk of early cardiovascular events within six months of transplantation. However, coronary intervention in KTCs with severe CAD was not associated with lower rates of post-transplant cardiovascular events. Conclusion: Pre-transplant coronary angiography to identify severe CAD is of highest yield in KTCs with a history of CAD or an LVEF < 50%. Our findings indicate that the identification of severe CAD in KTCs has prognostic significance for the early post-transplant period. Optimization of medical therapy in these high-risk KTCs may improve post-transplant cardiovascular outcomes.
