Association between Dental Scaling and Reduced Risk of End-Stage Renal Disease: A Nationwide Matched Cohort Study.

ABSTRACT: Periodontitis is prevalent in patients with chronic kidney disease (CKD) and is also associated with kidney function decline. It is unclear whether dental scaling treatment prevents the progression of CKD. In a nationwide cohort study, Taiwan's National Health Insurance Research Database was used to select people with CKD. Propensity score-matching procedures were performed to compare the long-term risk of end-stage renal disease (ESRD) between CKD patients with and without the receipt of dental scaling. A total of 33,637 matched pairs with CKD were included, with 503,373 person-years of follow-up for analyses. Dental scaling was significantly associated with a lower risk of ESRD (adjusted hazard ratio (aHR): 0.83, 95% confidence interval (CI): 0.77-0.90). In addition, there was a dose-dependent relationship between the frequency of dental scaling and a reduced risk of ESRD. Dental scaling was also linked to reduced risks of major adverse cardiovascular events (aHR: 0.91, 95% CI: 0.87-0.95), sepsis (aHR: 0.81, 95% CI: 0.77-0.85), and all-cause mortality (aHR: 0.81, 95% CI: 0.76-0.87). Dental scaling was significantly associated with lower risks of progression to ESRD in patients with CKD. Regular dental scaling may serve as a prophylactic measure for kidney function decline.

Project description:Objectives:No previous study has evaluated the risks associated with transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma in patients on hemodialysis (HD) for end stage renal disease (ESRD), because invasive treatment is rarely performed for such patients. We used a nationwide database to investigate in-hospital mortality and complication rates following TACE in patients on HD for ESRD. Methods:Using the Japanese Diagnosis Procedure Combination database, we enrolled patients on HD for ESRD who underwent TACE for hepatocellular carcinoma. For each patient, we randomly selected up to four non-dialyzed patients using a matched-pair sampling method based on the patient's age, sex, treatment hospital, and treatment year. In-hospital mortality and complication rates were compared between dialyzed and non-dialyzed patients following TACE. Results:We compared matched pairs of 1551 dialyzed and 5585 non-dialyzed patients. Although the complication rate did not differ between the dialyzed and non-dialyzed ESRD patients [5.7% vs 5.8%, respectively; odds ratio, 0.99; 95% confidence interval (0.79-1.23); p = 0.90], the in-hospital mortality rate was significantly higher in dialyzed ESRD patients than in non-dialyzed patients [2.2% vs 0.97%, respectively; odds ratio, 2.21; 95% confidence interval (1.44-3.40); p < 0.001]. Among the dialyzed patients, the mortality rate was not significantly associated with sex, age, Charlson comorbidity index, or hospital volume. Conclusions:The in-hospital mortality rate following TACE was 2.2 % and was significantly higher in dialyzed than in non-dialyzed ESRD patients. The indications for TACE in HD-dependent patients should be considered carefully with respect to the therapeutic benefits v s risks. Advances in knowledge:In hospital mortality rate following TACE in dialyzed patients was more than twice compared to non-dialyzed patients. Post-procedural complication following TAE in ESRD onHD patients was 5.7%, and did not differ from that in non dialyzed patients.

Project description:OBJECTIVE:Serum albumin is a marker of malnutrition and inflammation and has been demonstrated as a strong predictor of mortality in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. Yet, whether serum albumin levels in late-stage CKD are associated with adverse outcomes after the transition to ESRD is unknown. We hypothesize that lower levels and a decline in serum albumin in late-stage CKD are associated with higher risk of mortality and hospitalization rates 1 year after transition to ESRD. DESIGN AND METHODS:This retrospective cohort study included 29,124 US veterans with advanced CKD transitioning to ESRD between 2007 and 2015. We evaluated the association of pre-ESRD (91 days before transition) serum albumin with 12-month post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates as well as the association of 1-year pre-ESRD albumin slope and 12-month post-ESRD mortality using hierarchical multivariable adjustments. RESULTS:There was a negative linear association between serum albumin and all-cause mortality, such that risk doubled (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.87, 2.28) for patients with the lowest serum albumin <2.8 g/dL (ref: ?4.0 g/dL) after full adjustment. A consistent relationship was observed between serum albumin and cardiovascular and infection-related mortality, and hospitalization outcomes. An increase in serum albumin of >0.25 g/dL/year was associated with reduced mortality risk (HR: 0.76, 95% CI: 0.63, 0.91) compared with a slight decline in albumin (ref: >-0.25 to 0 g/dL/year), whereas a decline more than 0.5 g/dL/year was associated with a 55% higher risk in mortality (HR: 1.55, 95% CI: 1.43, 1.68) in fully adjusted models. CONCLUSIONS:Lower pre-ESRD serum albumin was associated with higher post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates. Declining serum albumin levels in the pre-ESRD period were also associated with worse 12-month post-ESRD mortality.

Project description:BackgroundPrevious studies have demonstrated that early pre-end-stage renal disease (ESRD) nephrology care could improve postdialysis prognosis. However, less is known about the specific types of interventions responsible for the improved outcomes. We hypothesized that more frequent predialysis laboratory testing is associated with better postdialysis outcomes in incident ESRD patients.MethodsIn all, 23?089 patients with available outpatient laboratory tests performed during the 2-year predialysis (i.e. prelude) period were identified from a total of 52?172 American veterans with chronic kidney disease (CKD) transitioning to dialysis between October 2007 and September 2011. The associations between the frequency of combined laboratory tests, including serum creatinine, serum potassium and hemoglobin (test trio), with postdialysis mortality and hospitalization were examined in multivariable adjusted Cox and logistic regression models.ResultsWhen entering the 2-year prelude period, the mean age (Standard Deviation) of the patients was 66.2 (SD 11.3)?years and the mean estimated glomerular filtration rate was 46.8 (SD 23.9)?mL/min/1.73 m2. In all, 14% of patients had the test trio performed less than twice in 24?months and 8.9% had the trio measured more often than every other month. Over a 2.5-year median postdialysis follow-up period, 15?303 (66.3%) patients died (mortality rate 260/1000 patient-years). The adjusted hazard ratio of all-cause mortality and adjusted odds ratio of the composite of hospitalization or death associated with lab testing done >12/24?months compared with 2-?4/24 months were 0.68 [95% confidence interval (CI) 0.65-0.73] and 0.70 (95% CI 0.62-0.79), respectively.ConclusionsMore frequent laboratory testing in patients with advanced CKD is associated with better clinical outcomes after dialysis. Further examination in clinical trials is needed before the implementation of more frequent laboratory testing in clinical practice.
