Otorhinolaryngological dysfunctions induced by chronic kidney disease in pre- and post-transplant stages.

ABSTRACT: PURPOSE:Otorhinolaryngological abnormalities are common complications of chronic kidney disease (CKD) and its treatment. The main aim of this study was to provide a brief and precise review of the current knowledge regarding CKD and its treatment-related influence on head and neck organs. METHODS:The Medline and Web of Science databases were searched using the terms "chronic kidney disease", "kidney transplantation", "immunosuppression", "dialysis" in conjunction with "otorhinolaryngological manifestation". Articles that did not address the topics, low-quality studies, case reports, and studies based on nonsignificant cohorts were excluded, and the full text of remaining high-quality, novel articles were examined and elaborated on. RESULTS:Patients with CKD are prone to develop sensorineural hearing loss, tinnitus, recurrent epistaxis, opportunistic infections including oropharyngeal candidiasis or rhino-cerebral mucormycosis, taste and smell changes, phonatory and vestibular dysfunctions, deep neck infections, mucosal abnormalities, gingival hyperplasia, halitosis or xerostomia. Immunosuppressive therapy after kidney transplantation increases the risk of carcinogenesis, both related and not-related to latent viral infection. The most commonly viral-related neoplasms observed in these patients are oral and oropharyngeal cancers, whereas the majority of not-related to viral infection tumors constitute lip and thyroid cancers. CKD-related otorhinolaryngological dysfunctions are often permanent, difficult to control, have a significant negative influence on patient's quality of life, and can be life threatening. CONCLUSION:Patients with CKD suffer from a number of otorhinolaryngological CKD-induced complications. The relationship between several otorhinolaryngological complications and CKD was widely explained, whereas the correlation between the rest of them and CKD remains unclear. Further studies on this subject are necessary.

Project description:INTRODUCTION:Decreased insulin sensitivity blunts the normal increase in gene expression from skeletal muscle after exercise. In addition, chronic inflammation decreases insulin sensitivity. Chronic kidney disease (CKD) is an inflammatory state. How CKD and, subsequently, kidney transplantation affects skeletal muscle gene expression after exercise are unknown. METHODS:Study cohort: non-diabetic male/female 4/1, age 52±2 years, with end-stage CKD who underwent successful kidney transplantation. The following were measured both pre-transplant and post-transplant and compared to normals: Inflammatory markers, euglycemic insulin clamp studies determine insulin sensitivity, and skeletal muscle biopsies performed before and within 30 minutes after an acute exercise protocol. Microarray analyses were performed on the skeletal muscle using the 4x44K Whole Human Genome Microarrays. Since nuclear factor of activated T cells (NFAT) plays an important role in T cell activation and calcineurin inhibitors are mainstay immunosuppression, calcineurin/NFAT pathway gene expression was compared at rest and after exercise. Log transformation was performed to prevent skewing of data and regression analyses comparing measures pre- and post-transplant performed. RESULT:Markers of inflammation significantly improved post-transplantation. Insulin infusion raised glucose disposal slightly lower post-transplant compared to pre-transplant, but not significantly, thus concluding differences in insulin sensitivity were similar. The overall pattern of gene expression in response to exercise was reduced both pre-and post-transplant compared to healthy volunteers. Although significant changes were observed among NFAT/Calcineurin gene at rest and after exercise in normal cohort, there were no significant differences comparing NFAT/calcineurin pathway gene expression pre- and post-transplant. CONCLUSIONS:Despite an improvement in serum inflammatory markers, no significant differences in glucose disposal were observed post-transplant. The reduced skeletal muscle gene expression, including NFAT/calcineurin gene expression, in response to a single bout of exercise was not improved post-transplant. This study suggests that the improvements in inflammatory mediators post-transplant are unrelated to changes of NFAT/calcineurin gene expression.

Project description:Background and objectivesMineral and bone disorders (MBDs) are common in long-term dialysis patients and are risk factors for unfavorable outcomes. The associations between pretransplant levels of MBD surrogates and outcomes after kidney transplantation are not clear.Design, setting, participants, & measurementsData from the Scientific Registry of Transplant Recipients up to June 2007 were linked to the 5-year (July 2001-June 2006) cohort of a large dialysis organization in the United States. All dialysis patients who received a kidney transplant during this period were identified and divided into groups according to increments of pretransplant MBD markers. Unadjusted and multivariate adjusted predictors of transplant outcomes were examined.ResultsThe 11,776 patients were aged 47 ± 14 years and 39% were women. Compared with recipients with pretransplant time-averaged serum alkaline phosphatase of 80-120 U/L, recipients with pretransplant serum alkaline phosphatase of 120-160 and ≥160 U/L had 49% and 64% higher graft failure censored all-cause mortality in multivariable adjusted models. There was no significant association between time-averaged serum alkaline phosphatase categories and risk of death censored graft failure, delayed graft function (DGF), or acute rejection (AR). Compared with recipients with pretransplant time-averaged serum parathyroid hormone (PTH) levels of 150-300 pg/ml, there was no significant association with graft censored death among recipients with pretransplant serum PTH ≥800 pg/ml. In addition, the risk of graft failure, DGF, and AR did not show any association with time-averaged serum intact PTH level. There was no significant association between time-averaged serum calcium categories and risk of graft failure censored death, DGF, and AR.ConclusionsIn this cohort, hemodialysis patients with pretransplant serum alkaline phosphatase >120 U/L have unfavorable post-transplant mortality, whereas there was no association between serum PTH and serum calcium levels and post-transplant outcomes.

Project description:BackgroundBehavioral factors, such as lifestyle, have been shown to explain approximately 24% of the excess risk of chronic kidney disease (CKD) among African Americans. However, there are limited intervention studies culturally tailored to African Americans with type 2 diabetes mellitus and CKD.ObjectiveThe main objective of this study was to examine the feasibility and preliminary efficacy of a culturally tailored lifestyle intervention among African Americans with type 2 diabetes mellitus and CKD.MethodsA pre-post design was used to test the feasibility of a lifestyle intervention in 30 African American adults recruited from the Medical University of South Carolina between January 2017 and February 2017. A research nurse delivered the manualized study intervention weekly for 6 weeks. Clinical outcomes (hemoglobin A1c, blood pressure, and estimated glomerular filtration rate [eGFR]) were measured at baseline and postintervention. Disease knowledge, self-care, and behavior outcomes were also measured using validated structured questionnaires at baseline and postintervention. Descriptive statistics and effect sizes were calculated to determine clinically important changes from baseline.ResultsSignificant pre-post mean differences and decreases were observed for hemoglobin A1c (mean 0.75%, 95% CI 0.16-1.34; P=.01), total cholesterol (mean 16.38 mg/dL, 95% CI 5.82-26.94; P=.004), low-density lipoprotein (mean 13.73 mg/dL, 95% CI 3.91-23.54; P=.008), and eGFR (mean 6.73 mL/min/1.73m2, 95% CI 0.97-12.48; P=.02). Significant pre-post mean differences and increases were observed for CKD self-efficacy (mean -11.15, 95% CI -21.55 to -0.75; P=.03), CKD knowledge (mean -2.62, 95% CI -3.98 to -1.25; P<.001), exercise behavior (mean -1.21, 95% CI -1.96 to -0.46; P=.003), and blood sugar testing (mean -2.15, 95% CI -3.47 to -0.83; P=.003).ConclusionsThis study provides preliminary data for a large-scale appropriately powered randomized controlled trial to examine a culturally tailored lifestyle intervention in African Americans with type 2 diabetes mellitus and CKD in order to improve clinical, knowledge, self-care, and behavior outcomes in this population.
