[PMID: 36906234 DOI: 10.1016/j.diabres.2023.110618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/15/2023] [Accepted: 03/06/2023] [Indexed: 03/11/2023]
Abstract
AIMS To assess whether, besides "traditional" risk factors, overall oxidative stress, oxidized lipoproteins, and glycemic variability are associated with early macro-vascular damage in type 1 diabetes (T1D). METHODS In 267 children/adolescents with T1D (130 girls, age 9.1-23.0 years) we evaluated: derivatives of reactive oxygen metabolites [d-ROMs], serum total antioxidant capacity [TAC] and oxidized LDL-cholesterol [oxLDL]; markers of early vascular damage (Lipoprotein-associated phospholipase A2 [Lp-PLA2], z-score of carotid intima-media thickness [z-cIMT] and carotid-femoral pulse wave velocity [z-PWV]); CGM metrics of four weeks preceding the visit, central systolic/diastolic blood pressures (cSBP/cDBP), and HbA1c, z-score of BP (z-SBP/z-DBP) and circulating lipids longitudinally collected since T1D onset.. Three general linear models were built with z-cIMT, z-PWV adjusted for current cDBP, and Lp-PLA2 as independent variables. RESULTS The z-cIMT was associated with male gender (B = 0.491, η2 = 0.029, p = 0.005), cSBP (B = 0.023, η2 = 0.026, p = 0.008) and oxLDL (B = 0.022, η2 = 0.022, p = 0.014). The z-PWV was associated with diabetes duration (B = 0.054, η2 = 0.024, p = 0.016), daily insulin dose (B = 0.52, η2 = 0.018, p = 0.045), longitudinal z-SBP (B = 0.18, η2 = 0.018, p = 0.045) and dROMs (B = 0.003, η2 = 0.037, p = 0.004). Lp-PLA2 was associated with age (B = 0.221, η2 = 0.079, p = 3*10-6), oxLDL (B = 0.081, η2 = 0.050, p = 2*10-4), longitudinal LDL-cholesterol (B = 0.031, η2 = 0.043, p = 0.001) and male gender (B = -1.62, η2 = 0.10, p = 1.3*107). CONCLUSIONS Oxidative stress, male gender, insulin dose, diabetes duration and longitudinal lipids and blood pressure, contributed to the variance of early vascular damage in young patients with T1D.

The significance of central blood pressure for cardiovascular target organ damage in children and adolescents after kidney transplantation. Pediatr Nephrol 2023:10.1007/s00467-022-05857-y. [PMID: 36629915 PMCID: PMC10393860 DOI: 10.1007/s00467-022-05857-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 12/08/2022] [Accepted: 12/08/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Cardiovascular (CV) complications are important causes of morbidity and mortality in children after kidney transplantation (KTx). In adults, central blood pressure (cBP) is an accepted predictor of CV sequelae. We aimed to assess the prognostic value of cBP over peripheral blood pressure (pBP) for existing CV damage. METHODS We measured cBP and pBP in 48 pediatric KTx recipients (mean age: 13.5 ± 4.2 years). Assessment of left ventricular mass index (LVMI) and aortic pulse wave velocity (PWV) allowed detection of CV target organ damage. LVMI and PWV were used as endpoints in multivariable linear regression models, in which cBP and pBP were compared for their predictive value. RESULTS Using cBP z-scores, we identified a larger number of patients with uncontrolled or untreated hypertension compared to pBP (36% vs. 7%). Central systolic blood pressure (cSBP) was a significant independent predictor of LVMI, while peripheral systolic blood pressure (pSBP) was not. Comparing central (cDBP) and peripheral (pDBP) diastolic blood pressure for their predictive value on PWV revealed a greater estimate for cDBP (0.035 vs. 0.026 for pDBP) along with a slightly better model fit for cDBP. CONCLUSIONS Our data in a small group of patients provide first evidence that cBP measurements in pediatric KTx recipients might be helpful in identifying patients at risk for the development of CV sequelae. Investigating a larger patient number, ideally repeatedly, is needed to create further evidence supporting our findings. In light of available devices measuring cBP noninvasively, the implementation of such clinical studies post-KTx care should be feasible. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
INTRODUCTION Type 1 diabetes mellitus (T1D) is a chronic disease leading to cardiovascular complications that can be diagnosed early as subclinical vascular damage. To prevent such damage, it is important to increase knowledge of the effects of the different cardiovascular risk factors in patients with T1D. The aim of our study was to assess possible associations between markers of subclinical arterial damage and traditional cardiovascular risk factors, with a special focus on peripheral blood pressure and central blood pressure (cBP), in a sample of young adults with T1D. PATIENTS AND METHODS The study included 172 T1D patients (mean age 24.7 ± 8.7 years, duration of T1D 13.5 ± 9.6 years). Pulse wave velocity (PWV), pulse wave analysis and cBP were assessed by tonometry (SphygmoCor Xcel). Carotid intima-media thickness (cIMT) and carotid distensibility coefficient (cDC) were assessed by high-resolution echo-Doppler analysis and further examined with dedicated hardware. RESULTS Seventeen patients (10.1%) were classified as hypertensive by office peripheral blood pressure, and 48 patients (27.9%) were classified as hypertensive by cBP. One hundred sixteen patients (68.8%) had cDC under the range of normality, one patient had a PWV (0.6%) above 10 m/s, and no patients had a cIMT above 0.9 mm. In multivariable analysis, central SBP, but not metabolic parameters, remained associated with all the markers of subclinical arterial damage [cIMT ( β = 0.288 ± 0.001; P < 0.001), PWV ( β = 0.374 ± 0.007; P < 0.001), cDC ( β = -0.149 ± 0.055; P = 0.029)]. CONCLUSION The independent association between cBP and markers of subclinical vascular damage underlines the importance of haemodynamic factors in the development of early signs of macrovascular disease in T1D patients. Further studies are warranted to better define the role of cBP to stratify cardiovascular risk, to individualize the need for follow-up and to tailor preventive strategies in T1D patients.
