Temporal Trends in Renal Replacement Therapy in Community-Based People with or without Type 2 Diabetes: The Fremantle Diabetes Study.

ABSTRACT: Although rates of cardiovascular disease complicating type 2 diabetes are declining, equivalent data for renal replacement therapy (RRT) are conflicting. The aim of this study was to characterize temporal changes in RRT incidence rates (IRs) in Australians with or without type 2 diabetes. Participants with type 2 diabetes from the Fremantle Diabetes Study Phases I (FDS1; n = 1291 recruited 1993-1996) and II (FDS2; n = 1509 recruited 2008-2011) were age-, sex- and postcode-matched 1:4 to people without diabetes and followed for first hospitalization for/with RRT. Five-year IRs, IR ratios (IRRs) for those with versus without diabetes in FDS1 and FDS2, and IR differences (IRDs), were calculated. The 13,995 participants had a mean age of 64.8 years and 50.4% were males. For the type 2 diabetes cohorts, the 5-year RRT IR was nearly threefold higher in FDS2 versus FDS1 (IRR (95% CI): 2.85 (1.01-9.87)). Sixteen more participants with type 2 diabetes/10,000 person-years received RRT in FDS2 than FDS1 compared with an IRD of 2/10,000 person-years in those without diabetes. Type 2 diabetes increased RRT risk at least 5-fold. This increased risk was greater in Aboriginal participants who were relatively young when RRT was initiated and more prone to rapid progression to RRT. Multivariable analysis using the combined FDS type 2 diabetes cohorts confirmed albuminuria as a strong independent RRT risk factor. The incidence of RRT is increasing substantially in Australians with type 2 diabetes, especially in Aboriginals who progress to RRT more rapidly at a younger age than non-Aboriginals.

Project description:BackgroundThere is a paucity of contemporary data on the prevalence and prognostic significance of cardiac autonomic neuropathy (CAN) from community-based cohorts with type 2 diabetes assessed using gold standard methods. The aim of this study was to assess these aspects of CAN in the longitudinal observational Fremantle Diabetes Study Phase II (FDS2).MethodsFDS2 participants were screened at baseline using standardised cardiovascular reflex tests (CARTs) of heart rate variation during deep breathing, Valsalva manoeuvre and standing. CAN (no/possible/definite) was assessed from the number of abnormal CARTs. Multinomial regression identified independent associates of CAN status. Cox proportional hazards modelling determined independent baseline predictors of incident heart failure (HF) and ischaemic heart disease (IHD), and all-cause mortality.ResultsOf 1254 participants assessed for CAN, 86 (6.9%) were outside CART age reference ranges and valid CART data were unavailable for 338 (27.0%). Of the remaining 830 (mean age 62.3 years, 55.3% males, median diabetes duration 7.3 years), 51.0%, 33.7% and 15.3% had no, possible or definite CAN, respectively. Independent associates of definite CAN (longer diabetes duration, higher body mass index and resting pulse rate, antidepressant and antihypertensive therapies, albuminuria, distal sensory polyneuropathy, prior HF) were consistent with those reported previously. In Kaplan-Meier analysis, definite CAN was associated with a lower likelihood of incident IHD and HF versus no/possible CAN (P < 0.001) and there was a graded increase in all-cause mortality risk from no CAN to possible and definite CAN (P < 0.001). When CAN category was added to the most parsimonious models, it was not a significant independent predictor of IHD (P ≥ 0.851) or HF (P ≥ 0.342). Possible CAN (hazard ratio (95% CI) 1.47 (1.01, 2.14), P = 0.046) and definite CAN (2.42 (1.60, 3.67), P < 0.001) increased the risk of all-cause mortality versus no CAN.ConclusionsRoutine screening for CAN in type 2 diabetes has limited clinical but some prognostic value.

Project description:Aims/hypothesisInfection is an under-recognised but important complication in people with diabetes. Studies on temporal trends in incidence of infection in this population are limited. We report the trends in infection-related hospitalisation in people with diabetes and compared hospitalisation rates between people with and without diabetes in Hong Kong.MethodsHospital admissions with infection, including pneumonia, influenza, tuberculosis, kidney infection, urinary tract infection, cellulitis, osteomyelitis, foot infection and sepsis, listed as principal diagnosis occurring between 2001 and 2016 were identified from people with diabetes in the electronic medical record system of the Hong Kong Hospital Authority. Data on hospitalisation for a subset of these infections in the general population between 2007 and 2016 were obtained from the Department of Health. The number of people with diabetes ranged between 117,322 in 2001 and 570,929 in 2016, and the number without diabetes ranged between 5,242,614 in 2007 and 5,593,153 in 2016. Joinpoint regression was used to describe the trends.ResultsIn people with diabetes, over a period of 16 years, the age-standardised annual rates of hospitalisation decreased for tuberculosis but increased for influenza; rates of hospitalisation for pneumonia increased up until 2004/2005 and declined in men and stabilised in women. The rates of hospitalisation for most infection types were unchanged or increased in the 20-44 year and 45-64 year age groups and decreased in those aged 65 years or above. Trends for most of the infections were similar when comparing sexes. Between 2007 and 2016, the rate ratios of hospitalisation for most infection types between people with and without diabetes were stable, and the rate ratios remained higher in people with diabetes, ranging from 1.3-1.4 for pneumonia to 3.2-4.9 for kidney infections in 2016 compared with non-diabetic individuals.Conclusions/interpretationDespite advances in medical care, hospitalisation due to infections remains a major healthcare burden in people with diabetes.
