RESUMO

Transplant centers and physicians in the United States have limited guidance on the information which they can and cannot provide to transplant candidates regarding donors of potential organs. Patients may refuse organs for a variety of reasons ranging from pernicious requests including racism to misinformation about emerging medicine as with the COVID-19 vaccine and infection. Patient autonomy, organ stewardship, and equity are often at odds in these cases, but precedent indeed exists to help address these challenges. This work uses such cases to highlight the urgent need for uniform, national policy prohibiting informational requests unrelated to well-established risks.

RESUMO

PROBLEM: Most Americans indicate they are religious and/or spiritual and wish to have their beliefs taken into account when engaging with health care providers, yet gaps in medical education and health care practice remain. To underscore the importance of spirituality as a significant social determinant of health, a team at the Icahn School of Medicine at Mount Sinai in New York developed mandatory spirituality and health training for students integrated into all 4 years of the undergraduate medical education curriculum. APPROACH: From 2014 to 2020, a small group of faculty took an innovative approach, launching the initiative and expanding the team by engaging interprofessional faculty and staff from across the institution. The team used an iterative process to integrate 4 distinct modules into 4 existing courses, spanning the 4 years of medical school. OUTCOMES: The majority of students found that the spirituality and health curriculum was valuable to training and professional development. They appreciated the importance of patients' spiritual needs, valued learning about the role chaplains play in patient care and how to initiate a consult, and indicated they intended to integrate spiritual history taking in their patient care. With respect to process, 3 key factors-establishing an interprofessional team, working through an iterative process, and integrating the curriculum into existing courses-were critical to designing and implementing the modules. NEXT STEPS: The team aims to expand and improve the curriculum by linking learning to specific standardized competencies as well as developing more specific performance assessments to demonstrate achievement of competencies. Professional development efforts will be enhanced so faculty can better model and reinforce the integration of spirituality into health care practices and expand the curriculum on spirituality and health into graduate medical education.

RESUMO

BACKGROUND: Our center has one of the largest representations of African Americans in listed and transplanted patients. We investigated if and how racial differences affect outcomes in our patient population. METHODS: We performed a retrospective analysis of all kidney transplants in African American and (non-Hispanic) White patients in our center from 1/1/2005 to 12/31/2014. Cox regression was performed to evaluate the adjusted hazard ratios for graft loss. We investigated the influence of socioeconomic status on transplant outcomes. We stratified our patients into three groups based on income: lower (<$50 000 annual household income), medium ($50 000-100 000 annual household income), and higher (>$100 000 annual household income. RESULTS: There were 1333 patients in our study, 696 Whites and 637 African Americans. The 1-, 5-, and 10-year graft survival between the two groups was 96.5% vs 91.1%, 89% vs 80.7%, and 77% vs 66.3%, respectively (P < .001 by Log Rank, Breslow and Taron-Ware). When we compared the two groups separately in each income category, we found no statistical difference between African Americans and Whites in graft survival. In the regression model, income and not race was the significant factor influencing graft survival (P < .001 vs P = .61).

RESUMO

Rejection rates in HIV-infected kidney transplant (KTx) recipients are higher than HIV-negative recipients. Immunosuppression and highly active antiretroviral therapy (HAART) protocols vary with potentially significant drug-drug interactions, likely influencing outcomes. This is an IRB-approved, single-center, retrospective study of adult HIV-infected KTx patients between 5/2009 and 12/2014 with 3-year follow-up, excluding antibody-depleting induction. A total of 42 patients were included; median age was 52 years, 81% male, 50% African American, 29% Hispanic, 17% Caucasian. The most common renal failure etiology was hypertensive nephrosclerosis (50%) with 5.8 median years of pre-transplant dialysis. All patients received IL-2 receptor antagonist, were maintained on tacrolimus (76%) or cyclosporine (17%), and 40% received ritonavir-boosted PI-based HAART (rtv+) regimen. Patient and graft survival at 3 years were 93% and 90%. At 1-, 2-, and 3-year time points, median serum creatinine was 1.49, 1.35, and 1.67; treated biopsy-proven rejection was 38%, 38%, and 40.5%; and 92% of episodes were acute rejection. At these time points, rejection rates were significantly higher with boosted PI HAART regimens compared to other HAART regimens, 59% vs 24% (P = 0.029), 59% vs 24% (P = 0.029), and 68% vs 24% (P = 0.01). Despite higher rejection rates, HIV-infected KTx recipients have reasonable outcomes. Given significantly higher rejection rates using rtv+ regimens, alternative HAART regimens should be considered prior to transplantation.

RESUMO

Simultaneous liver-kidney allocation protocols allocate dual organs based on a sustained eGFR of 30 mL/min or less. A 2017-UNOS update includes CKD3 as dual organ candidates but only when the listing eGFR is <30 mL/min while recommending a "safety net" for prioritized kidney listing post-LT. We retrospectively reviewed adult LTs examine whether the UNOS proposal captured the LT population at highest risk for developing post-LT ESRD. Among 290 LT recipients, 67 had pre-LT CKD3, 141 had AKI, of whom 47 required dialysis (<4 weeks). During follow-up, 25 (8.62%) developed ESRD, while 70 (24.1%) died. In adjusted Cox models, CKD3 had an independent association with post-LT ESRD (adjusted HR 4.8; P = 0.001), independent of AKI. Interestingly, CKD3 with listing GFR >30 mL/min was still significantly associated with post-LT ESRD. AKI was associated with reduced post-LT survival (adjusted HR 1.9; P = 0.02), albeit only in the first-year post-LT. Severe AKI-D was associated with post-LT ESRD and mortality. The safety net would have captured only 60% of all post-LT ESRD cases in our cohort. Pre-LT CKD3 was associated with increased risk of post-LT ESRD above the recommended cutoff for listing GFR. These findings, if generalizable in larger cohorts have important implications for dual organ allocation.

RESUMO

Introduction: Despite many patients wanting physicians to inquire about their religious/spiritual beliefs, most physicians do not make such inquiries. Among physicians who do, surgeons are less likely than family and general practitioners and psychiatrists to do so. Methods: To address this gap, we developed a 60-minute curriculum that follows the Kolb cycle of experiential learning for third-year medical students on their surgery/anesthesiology clerkship. The session includes definitions of religion/spirituality, an overview of the literature on spirituality in surgery, a review of the FICA Spiritual History Tool, discussion of the role of the chaplain and the process of initiating a chaplain consult, and three cases regarding the spiritual needs of surgical patients. Results: In total, 165 students participated in 10 sessions over 13 months. Of these, 120 students (73%) provided short-term feedback. Overall, 82% rated the session above average or excellent, and 72% stated the session was very relevant to patient care. To improve the session, students recommended assigning key readings, discussing more cases, role-playing various scenarios, inviting patients to speak, practicing mock interviews, and allowing for more self-reflection and discussion. Long-term feedback was provided by 105 students (64%) and indicated that the spirituality session impacted their attitudes about the role of religion/spirituality in medicine and their behaviors with patients. Discussion: We have designed a successful session on spirituality for third-year students on their surgery/anesthesiology clerkship. Students reported it to be a positive addition to the curriculum. The session can be modified for other surgical subspecialties and specialties outside of surgery.

RESUMO

INTRODUCTION: Patients with end-stage renal disease are under increased risk for renal cell carcinoma development, and radical nephrectomy is the preferred treatment in this setting. Owing to the increased surgical morbidity and mortality, active surveillance (AS) may be a valid option for treatment of small renal masses (SRM). As there is a lack of high-level evidence for treatment recommendations, we performed a survey analysis to analyze the treatment patterns of transplant surgeons. MATERIAL AND METHODS: A 21-question online survey designed to analyze the practice patterns to treat SRM in renal transplant recipient candidates was sent to active transplant centers in the United States. The list of recipients to whom the survey was distributed was obtained with permission from the American Society of Transplant Surgeons. RESULTS: We received 62 responses. All regions of United Network of Organ Sharing were represented. Radical nephrectomy was the preferred treatment (59%, n = 61), followed by AS (21.3%, n = 13), partial nephrectomy (14.8%, n = 9), and focal ablative therapy (4.9%, n = 3). Among the responders whose institutions did not allow AS, 77.4% indicated that if presented with long-term data showing safety of AS, they would perform immediate transplantation and monitor SRM. Responders were more likely to allow immediate transplantation after radical nephrectomy (77.4%), as opposed to partial nephrectomy (58.1%) and focal ablation (45.2%). CONCLUSION: Though radical nephrectomy is the preferred treatment, most transplant surgeons would consider AS if long-term safety data were available.

RESUMO

Belatacept is a non-nephrotoxic immunosuppressive agent, which may make it the ideal agent for patients with delayed or slow graft function on calcineurin inhibitors. There are limited data on conversion of patients to belatacept within 6 months of transplantation. Between January 2012 and December 2015, 16 patients were converted to belatacept for delayed or poor graft function (eGFR<30 mL/min/1.73 m2 , MDRD); three were HIV positive. Conversion protocols were analyzed in patients ≤4 months and 4-6 months post-transplantation. Mean serum creatinine levels after belatacept conversion were compared with preconversion levels. Patient survival was 100%, and graft survival was 88%. The mean creatinine fell from 3.9±1.82 mg/dL prebelatacept conversion to 2.1±1.1 mg/dL at 6 months and 1.9±0.47 mg/dL (median 1.8 mg/dL) at 12 months postconversion. There was no significant increased risk of rejection, infection, or malignancy. HIV parameters remained largely stable. Early conversion to belatacept in patients with DGF or slow graft function is safe and efficacious, in a single-center nonrandomized retrospective analysis.

RESUMO

INTRODUCTION: Renal transplantation candidates are a highly screened population. There are currently no guidelines or consensus on prostate cancer (CaP) screening in these patients. In light of the recent United States Preventive Services Task Force recommendations against prostate-specific antigen (PSA) screening, we conducted a survey of transplantation surgeons to gain a better understanding of practice patterns among U.S. centers. MATERIALS AND METHODS: A 14-question multiple-choice online survey was e-mailed to 195 U.S. renal transplantation centers. The questionnaire assessed CaP screening and treatment practices. The survey also evaluated characteristics of the respondent's institution. Descriptive statistics were used for each of the responses, and associations were made with program characterization using logistic or linear regression models. RESULTS: A total of 90 surgeons responded, representing 65 of 195 programs (33% response rate). Overall, 89% of respondents reported routinely screening for CaP in renal transplantation candidates and 71% had set guidelines for PSA screening. The most common age to start PSA screening was 50 years (51%) and 79% of respondents reported no age limit to stop PSA screening. Definitive treatment of CaP was required before proceeding to transplantation in 45% of respondents. Active surveillance was a viable option in 67% of responders. Most respondents (73%) replied that the waiting time for eligibility after treatment depended on the CaP stage and risk. CONCLUSIONS: Although most programs have guidelines on PSA screening in renal transplantation candidates, there is still variation nationwide in screening and treatment practices. AS is a viable treatment option in most of the programs. Our results suggest a benefit of a consensus panel to recommend guidelines in this population.

RESUMO

Although numerous studies highlighted the role of Epstein-Barr Virus (EBV) in B-cell transformation, the involvement of EBV proteins or genome in the development of the most frequent adult leukemia, chronic lymphocytic leukemia (CLL), has not yet been defined. We hypothesized that EBV microRNAs contribute to progression of CLL and demonstrated the presence of EBV miRNAs in B-cells, in paraffin-embedded bone marrow biopsies and in the plasma of patients with CLL by using three different methods (small RNA-sequencing, quantitative reverse transcription PCR [q-RT-PCR] and miRNAs in situ hybridization [miRNA-ISH]). We found that EBV miRNA BHRF1-1 expression levels were significantly higher in the plasma of patients with CLL compared with healthy individuals (p < 0 · 0001). Notably, BHRF1-1 as well as BART4 expression were detected in the plasma of either seronegative or seropositive (anti-EBNA-1 IgG and EBV DNA tested) patients; similarly, miRNA-ISH stained positive in bone marrow specimens while LMP1 and EBER immunohistochemistry failed to detect viral proteins and RNA. We also found that BHRF1-1 plasma expression levels were positively associated with elevated beta-2-microglobulin levels and advanced Rai stages and observed a correlation between higher BHRF1-1 expression levels and shorter survival in two independent patients' cohorts. Furthermore, in the majority of CLL cases where BHRF1-1 was exogenously induced in primary malignant B cells the levels of TP53 were reduced. Our findings suggest that EBV may have a role in the process of disease progression in CLL and that miRNA RT-PCR and miRNAs ISH could represent additional methods to detect EBV miRNAs in patients with CLL.

RESUMO

Mount Sinai Hospital in New York has a long history in the field of organ transplantation. The first kidney transplant at Mount Sinai was performed in 1967 by the late Dr. Lewis Burrows and the first laparoscopic donor nephrectomy in New York was performed at Mount Sinai in 1996. Over 3000 kidney transplantations have been performed at Mount Sinai. In the early 1990s, the first hepatitis C virus (HCV) positive patient at Mount Sinai underwent a kidney transplant and the first kidney transplant in a patient with human immunodeficiency virus (HIV) in New York was performed at Mount Sinai in 2001. In general, these patients have done well after renal transplantation, with outcomes similar to those seen in non-infected patients. This chapter will describe the evolution of immunosuppressive regimens in HCV positive and HIV positive patients, and will describe the outcomes of kidney transplantation in these patients. Given the favorable outcomes, it is reasonable to continue to offer renal transplantation as a treatment for end stage renal disease patients with HCV and/or HIV.

RESUMO

Patients with chronic lymphocytic leukemia (CLL) are known to have an increased incidence of second cancers, but the contribution of commonly used frontline therapies to the incidence of second cancers is unclear. We report on the characteristics, incidence, outcomes and factors associated with second cancers in 234 patients receiving fludarabine, cyclophosphamide and rituximab (FCR) based regimens in the frontline setting. The risk of second cancers was 2.38 times higher than the expected risk in the general population. Ninety-three patients (40%) had other cancers before and 66 patients (28%) after FCR. Rates of therapy related acute myeloid leukemia/myelodysplastic syndrome (t-AML/MDS) (5.1%) and Richter transformation (RT) (9%) were high, while solid tumors were not increased. Overall survival of patients with second cancers after frontline FCR was shorter (median of 4.5 years) compared to patients with and without prior cancers. Second cancer risk after frontline FCR is mainly due to high rates of t-AML/MDS and RT, and as speculated the survival of affected patients is shorter.

RESUMO

Although fludarabine, cyclophosphamide, and rituximab (FCR) together are established as a standard first-line treatment of younger patients with chronic lymphocytic leukemia (CLL), there is little information to guide the management of patients with CLL refractory to, or who have relapsed after, receiving frontline FCR treatment. To define optimal salvage strategy and identify patients unsuitable for retreatment with FCR, we examined the survival and treatment outcome of 300 patients enrolled in a phase 2 study of FCR. After a median 142 months of follow-up, 156 patients developed progressive CLL, with a median survival of 51 months after disease progression. The duration of first remission (REM1) was a key determinant of survival after disease progression and first salvage. Patients with a short REM1 (<3 years) had a short survival period, irrespective of salvage therapy received; these patients have high unmet medical needs and are good candidates for investigation of novel therapies. In patients with a long REM1 (≥3 years), salvage treatment with either repeat FCR or lenalidomide-based therapy results in subsequent median survival exceeding 5 years; for these patients, FCR rechallenge represents a reasonable standard of care.

RESUMO

BACKGROUND: Ibrutinib, an orally administered covalent inhibitor of Bruton's tyrosine kinase (BTK), is an effective treatment for relapsed chronic lymphocytic leukaemia (CLL). We investigated the activity and safety of the combination of ibrutinib with the monoclonal antibody rituximab in patients with high-risk CLL. METHODS: In this single-arm phase 2 study, we enrolled adult patients with high-risk CLL at the MD Anderson Cancer Center (Houston, TX, USA). All enrolled participants had high-risk cytogenetic abnormalities (deletion 17p, TP53 mutation, or deletion 11q) or a short progression-free survival (PFS <36 months) after previous first-line chemoimmunotherapy. Patients with symptomatic disease requiring therapy received 28-day cycles of once-daily ibrutinib 420 mg together with rituximab (375 mg/m(2), intravenously, every week during cycle 1, then once per cycle until cycle 6), followed by continuous daily single-agent ibrutinib 420 mg until disease progression or until toxicities or complications precluded further treatment. The primary endpoint was progression-free survival in the intention-to-treat population. This study is registered with ClinicalTrials.gov number NCT01520519, and is no longer accruing patients. FINDINGS: Between Feb 28, 2012, and Sept 11, 2012, we enrolled 40 patients with CLL with high-risk disease features, 20 of whom had deletion 17p (del[17p]) or TP53 mutations (16 previously treated, four untreated), 13 had relapsed CLL with deletion 11q (del[11q]), and seven a PFS less than 36 months after first-line chemoimmunotherapy. 18-month PFS in all patients was 78·0% (95% CI 60·6-88·5), whereas in those with a del(17p) or TP53 mutation it was 72·4% (45·6-87·6) Toxicity was mainly mild to moderate in severity (grade 1-2). Diarrhoea occurred in ten (25%) patients (grade 1 in nine patients and grade 2 in one), bleeding events in 14 (33%) patients (eight grade 1 and five grade 2), nausea or vomiting in 15 patients (38%) (ten grade 1 and five grade 2), and fatigue in seven (18%) patients (four grade 1 and three grade 2). Five patients (13%) had grade 3 infections (two lung infections, one upper respiratory tract infection, one sepsis, and one mucositis), and no grade 4 or 5 infections occurred. One patient had grade 4 neutropenia. INTERPRETATION: The encouraging safety and activity of ibrutinib and rituximab in this population of patients with high-risk CLL merits further investigation of this combination.

RESUMO

Richter syndrome (RS) is associated with poor outcome. The prognosis of patients with histologically aggressive chronic lymphocytic leukemia (CLL), or HAC, has not been studied. We aimed to correlate 2-deoxy-2-[(18)F]fluoroglucose/positron emission tomography (FDG/PET) data, histological diagnosis, clinical characteristics, and survival in patients with CLL. A total of 332 patients with CLL were histologically classified as: 95 RS, 117 HAC, and 120 histologically indolent CLL (HIC). HAC and RS patients had higher maximum standardized uptake value (SUVmax), more frequent constitutional symptoms, poorer performance status (PS), lower hemoglobin and platelets, and higher lactate dehydrogenase and ß-2-microglobulin. An SUVmax ≥10 strongly correlated with mortality (overall survival [OS], 56.7 vs 6.9 months in patients with SUVmax <10 vs ≥10). Survival of patients with RS and HAC was similar among patients with SUVmax <10 or ≥10. SUVmax ≥10, PS ≥2, bulky disease, and age ≥65 were independently associated with shorter OS. In patients undergoing both fine-needle aspiration and biopsy, the former proved diagnostically inadequate in 23%, 29%, and 53% of HIC, HAC, and RS, respectively. FDG/PET is a useful diagnostic tool in patients with CLL and suspected transformation. Patients with HAC show different characteristics and worse prognosis compared with those with HIC. Patients with different CLL phases, but similar SUVmax have similar outcome. Tissue biopsy should be preferred for diagnosing RS.

RESUMO

Fludarabine, cyclophosphamide and rituximab (FCR), the standard of care for the frontline treatment of patients with chronic lymphocytic leukemia (CLL), is associated with a high rate of neutropenia and infectious complications. Granulocyte macrophage colony-stimulating factor (GM-CSF) reduces myelosuppression and can potentiate rituximab activity. We conducted a clinical trial combining GM-CSF with FCR for frontline treatment of 60 patients with CLL. Eighty-six percent completed all six courses and 18% discontinued GM-CSF for toxicity: grade 3-4 neutropenia was observed in 30% of cycles, and severe infections in 16% of cases. The overall response rate was 100%. Both median event-free survival (EFS) and overall survival (OS) have not been reached. Longer EFS was associated with favorable cytogenetics. GM-CSF led to a lower frequency of infectious complications than in the historical FCR group, albeit similar EFS and OS.

RESUMO

BACKGROUND: The combination of fludarabine, cyclophosphamide, and rituximab (FCR) has produced improved response rates and a prolonged survival in patients with chronic lymphocytic leukemia (CLL). However, its therapeutic power is counterbalanced by significant hematologic toxicity. Persistent and new-onset cytopenia after the completion of FCR raise concern about disease recurrence, the development of therapy-related myeloid malignancies (TRMM), and infections. METHODS: A total of 207 patients with CLL who achieved complete response, complete response with incomplete bone marrow recovery, or nodular partial remission were analyzed after frontline FCR therapy. RESULTS: Three months after the completion of therapy, 35% of patients had developed grade 2 to 4 cytopenia (according to Common Terminology Criteria for Adverse Events [version 4.0]). Factors found to be associated with cytopenia at 3 months after therapy were older age, advanced Rai stage disease, and lower baseline blood counts. Moreover, patients with cytopenia were less likely to have completed 6 courses of therapy with FCR. At 6 months and 9 months after therapy, the prevalence of grade 2 to 4 cytopenia was 24% and 12%, respectively. No differences in progression-free survival and overall survival were noted between cytopenic and noncytopenic patients or between patients with persistent and new-onset cytopenia. The prevalence of TRMM was 2.3% and did not differ significantly between cytopenic and noncytopenic patients or between those with persistent and new-onset disease. Late infections were more common in patients who were cytopenic at 9 months (38%) and were mostly bacterial (67%). CONCLUSIONS: Cytopenia after the completion of therapy is a common complication of frontline FCR that improves over time, particularly for new-onset cases. The presence of persistent cytopenia (lasting up to 9 months after the completion of therapy) should not raise concern about CLL recurrence of the development of TRMM, but should encourage surveillance for bacterial infections for an additional 9 months.

RESUMO

Noncoding RNAs play a pivotal role in the pathogenesis of chronic lymphocytic leukemia (CLL). We hypothesized that microRNAs (miRs) are involved in the transition from monoclonal B-cell lymphocytosis (MBL) to CLL and tested miR-15a/16-1 cluster, miR-21, and miR-155 expression in purified B cells of normal individuals, individuals with MBL, and patients with CLL. When we analyzed 224 samples from 2 independent training and validation cohorts, we found that miR-155 was overexpressed in B cells from individuals with MBL, and even more so in B cells from patients with CLL, when compared with B cells from normal individuals. Furthermore, we were able to identify miR-155 in circulating microvesicles from both individuals with MBL and patients with CLL. Next, to examine the prognostic role of miR-155, we measured its expression level in plasma samples collected before treatment initiation in 228 patients with CLL. We found significantly higher miR-155 expression levels in patients who failed to achieve a complete response compared with those who experienced complete response. Our findings support the use of cellular and plasma levels of miR-155 as biomarkers for the risk of progression in individuals with MBL, as well as to identify patients with CLL who may not respond well to therapy.

RESUMO

PURPOSE: This analysis examined associations between gender and health-related quality of life (HRQOL) in patients with B-cell chronic lymphocytic leukemia (CLL) as they initiate therapy for CLL outside the clinical trial setting. METHODS: Baseline data were collected as part of Connect® CLL Registry, a prospective observational study initiated in community, academic, and government centers. Patient demographics and clinical characteristics were provided by clinicians. Patients reported HRQOL using the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Mean scores were analyzed, with statistical significance of differences determined by ANOVA. Multivariate analysis also considered age and line of therapy. RESULTS: Baseline HRQOL data were available for 1,140 patients: 710 (62 %) men and 430 (38 %) women from 161 centers. Patients were predominantly white (89 %) with mean age 69 ± 11 years. Women reported significantly worse global fatigue (P <0.0001), fatigue severity (P <0.0001), and fatigue-related interference (P = 0.0005) versus men (BFI). Pain/discomfort (P = 0.0077), usual activities (P = 0.0015), and anxiety/depression (P = 0.0117) were significantly worse in women than in men (EQ-5D). With women reporting a better social/family score (P = 0.0238) and men reporting a better physical score (P = 0.0002), the mean FACT-G total score did not differ by gender. However, the mean FACT-Leu total score was better among men versus women (P = 0.0223), primarily because the mean leukemia subscale score was significantly better among men (P <0.0001). Multivariate analysis qualitatively confirmed these findings. CONCLUSIONS: Connect® CLL Registry results indicate that significant differences exist in certain HRQOL domains, as women reported greater levels of fatigue and worse functioning in physical domains.
