Assessment of Carotid Intima Media Thickness and Left Ventricular Mass Index in Children with Idiopathic Nephrotic Syndrome

Objective Several studies revealed relations between low or high insulin-like growth factor I (IGF-I) levels and risk of cardiovascular diseases or mortality, whereas the mechanisms behind these associations are still unknown. Design The study aimed to explore the relations between IGF-I and changes in surrogate markers of cardiovascular disease including carotid intima-media thickness (IMT), left ventricular mass index (LVMI) and N-terminal pro-brain natriuretic peptide (NT-proBNP). Methods Longitudinal data of the population-based cohort Study of Health in Pomerania (SHIP) were used. IMT was measured by ultrasonography and LVMI was determined based on echocardiography. IGF-I and IGF-binding protein-3 (IGFBP-3) levels were measured by chemiluminescent immunoassays and the IGF-I/IGFBP-3 ratio was calculated. Mixed linear regression models adjusted for known cardiovascular confounders were performed. Results Statistical analyses demonstrated relations between low baseline IGF-I levels (beta for ΔIMT per s.d. increase −0.044 (s.e. 0.012)) or IGF-I/IGFBP-3 ratio (beta −0.045 (0.012)) and a long-term IMT increase. No associations between IGF-I, IGFBP-3 or IGF-I/IGFBP-3 ratio and changes in LVMI were detected. With respect to NT-proBNP sex-specific associations with IGF-I were found. In women, higher baseline IGF-I levels (beta for ΔNT-proBNP per s.d. increase 5.92 (2.2)) or IGF-I/IGFBP-3 ratio (beta 4.48 (2.2)) were related to an increase in NT-proBNP levels. Among men, U-shaped relations of baseline levels of IGF-I, IGFBP-3 and the IGF-I/IGFBP-3 ratio with an increase in NT-proBNP were found. Conclusions The study detected significant relations between IGF-I and long-term changes in IMT and NT-proBNP but not LVMI. These findings argue for different effects of the IGF-I axis with respect to various cardiovascular entities.

Background: To investigate the association between ankle-brachial index (ABI), left ventricular hypertrophy (LVH) and left ventricular mass index (LVMI) in a general population. Patients and methods: The study population consisted of 8,246 people aged 50 years and older who participated in the baseline survey of the Dong-gu Study conducted in Korea between 2007 and 2010. Trained research technicians measured LV mass using mode M ultrasound echocardiography and ABI using an oscillometric method. Results: After adjustment for risk factors and common carotid artery intima-media thickness (CCA-IMT) and the number of plaques, higher ABIs (1.10 1.19, 1.20 - 1.29, and ≥ 1.30) were significantly and linearly associated with high LVMI (1.10 - 1.19 ABI: β, 3.33; 95 % CI, 1.72 - 4.93; 1.20 - 1.29 ABI: β, 6.51; 95 % CI, 4.02 - 9.00; ≥ 1.30 ABI: β, 14.83; 95 % CI, 6.18 - 23.48). An ABI of 1.10 - 1.19 and 1.20 - 1.29 ABI was significantly associated with LVH (1.10 - 1.19 ABI: OR, 1.35; 95 % CI, 1.19 - 1.53; 1.20 - 1.29 ABI: OR, 1.59; 95 % CI, 1.31 - 1.92) and ABI ≥ 1.30 was marginally associated with LVH (OR, 1.73; 95 % CI, 0.93 - 3.22, p = 0.078). Conclusions: After adjustment for other cardiovascular variables and CCA-IMT and the number of plaques, higher ABIs are associated with LVH and LVMI in Koreans aged 50 years and older.
