RESUMO
Rationale and Objective: Latinx individuals are at a higher risk for kidney failure than non-Latinx White individuals; however, they are less likely to receive pre-kidney failure medical care. The objective of this study was to determine the feasibility and acceptability of a community health worker (CHW) intervention that facilitated access to medical care for Latinx individuals. Study Design: Single-arm prospective study. Setting and Participants: Latinx adults were found to have albuminuria or risk factors for kidney disease at community screening events in Austin, Texas. Intervention: A 6-month CHW intervention that facilitated the following: (1) obtaining medical insurance; (2) medical care coordination with primary and nephrology care; (3) kidney disease education; and (4) connection with local resources to address health-related social needs. Outcomes: Recruitment, retention, medical care linkage, and participant and CHW-reported satisfaction with the intervention. Results: Of the 173 individuals who attended the 2 community screening events, 49 agreed to participate in the study, of whom, 51% were men with a mean ± standard deviation (SD) age of 45 ± 14 years, and all self-identified as Mexican or Chicano. The mean ± SD estimated glomerular filtration rate (eGFR) was 110 ± 21 mL/min/1.73 m2 and 41% of the participants reported a urine albumin-creatinine ratio of ≥30 mg/g. Among those enrolled, 28 of the 49 (57%) completed at least 1 CHW visit, and 20 of 49 (41%) completed the intervention. 7 individuals who needed assistance with insurance obtained insurance, and 15 of 20 (75%) scheduled an appointment with a primary care physician within 180 days. Participants reported that the US health care previously seemed inaccessible but gained insurance, the ability to navigate the system, and the ability to help others in their community to access medical care because of the program. Limitations: Small sample size and a single community may limit generalizability. Conclusions: We reported the acceptability of a CHW intervention. We encountered challenges with feasibility and identified strategies to overcome them. Studies are needed to test the effect of CHW interventions on outcomes and kidney health disparities. Funding: National Kidney Foundation young investigator research grant to Dr Novick. Plain Language Summary: Latinx individuals are at a higher risk for kidney failure than non-Latinx White individuals; however, they are less likely to receive pre-kidney failure medical care. We piloted a community health worker intervention that connected people with risk factors or showed evidence of kidney dysfunction at community screening events with medical care. Our findings indicate the acceptability of the intervention. We encountered challenges with feasibility and identified strategies to overcome them.
RESUMO
Kidney transplantation (KT) is the optimal therapy for end-stage kidney disease (ESKD), resulting in significant improvement in survival as well as quality of life when compared with maintenance dialysis. The burden of cardiovascular disease (CVD) in ESKD is reduced after KT; however, it still remains the leading cause of premature patient and allograft loss, as well as a source of significant morbidity and healthcare costs. All major phenotypes of CVD including coronary artery disease, heart failure, valvular heart disease, arrhythmias and pulmonary hypertension are represented in the KT recipient population. Pre-existing risk factors for CVD in the KT recipient are amplified by superimposed cardio-metabolic derangements after transplantation such as the metabolic effects of immunosuppressive regimens, obesity, posttransplant diabetes, hypertension, dyslipidemia and allograft dysfunction. This review summarizes the major risk factors for CVD in KT recipients and describes the individual phenotypes of overt CVD in this population. It highlights gaps in the existing literature to emphasize the need for future studies in those areas and optimize cardiovascular outcomes after KT. Finally, it outlines the need for a joint 'cardio-nephrology' clinical care model to ensure continuity, multidisciplinary collaboration and implementation of best clinical practices toward reducing CVD after KT.

BACKGROUND: Patients with pretransplantation strong donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA) are at higher risk for rejection. We aimed to study the safety of kidney transplantation in patients with lower strength DSAs in a prospective cohort study. METHODS: Three hundred and seventy-three consecutive adult kidney transplant recipients with (DSA+; n=66) and without (DSA-; n=307) DSA were evaluated. Anti-HLA antibodies with mean fluorescence intensity values over 5,000 for HLA-A, HLA-B, and HLA-DR and more than 10,000 for HLA-DQ were reported as unacceptable antigens. Patients received transplant if flow cytometry T-cell and B-cell cross-match channel shift values were less than 150 and 250, respectively, with antithymocyte globulin and intravenous immunoglobulin induction treatment. RESULTS: Patients had a mean number of 1.6 ± 0.8 DSAs with a mean fluorescence intensity value of 2,815 ± 2,550. Twenty-seven percent were flow cytometry cross-match positive with T-cell and B-cell channel shift values of 129 ± 49 and 159 ± 52, respectively. During a median follow-up of 24 months (range, 6-50), there were no statistically significant differences in patient (99% vs. 95%) and graft survival (88% vs. 90%) rates between DSA+ and DSA- groups, respectively. Cumulative acute rejection rates of 11% in the DSA+ group and 12% in the DSA- group were similar. Two DSA+ (3%) and five DSA- (2%) patients developed chronic antibody-mediated rejection (3%). The mean serum creatinine levels were identical between the two groups (1.4 ± 0.6 mg/dL). CONCLUSION: Similar patient and graft survival, and acute rejection rates can be achieved in DSA+ patients compared to DSA- patients with pretransplantation immunologic risk assessment.
