Cross-sectional correlates of paraoxonase 1 and soluble intercellular adhesion molecule-1 in metabolic syndrome patients with and without diabetes

Background: Paraoxonase 1 (PON1) and soluble intercellular adhesion molecule-1(sICAM-1) are intricately involved in metabolic syndrome (MetS) and type 2 diabetes mellitus (T2DM) pathophysiology. This study aimed to investigate PON1 and sICAM-1 plasma levels in addition to correlating them with adiposity, atherogenicity and hematological indices in T2DM and MetS. Methods: This cross-sectional study composed of 28 healthy lean subjects (control), 29 normoglycemic MetS subjects and 30 MetS-Pre/T2DM. Results: The sICAM-1 levels (ng/ml) were markedly higher in the pre/diabetic MetS group (828 ± 250.37 versus controls’ 608.62 ± 184; p < 0.05). Conversely, PON1 levels (mlU/ml) were markedly lower in the pre/diabetic MetS group [252,700 (163,950, 362,800) versus controls’ 394,900 (212,550, 469,350); p < 0.05]. sICAM-1 correlated directly with all adiposity indices [conicity index (CI), waist circumference (WC), waist–hip ratio (WHR) waist-to-height (WHtR) ratio, hip circumference (HC) and body adiposity index (BAI)] in addition to the atherogenicity index of plasma (AIP). PON1 correlated negatively and significantly with CI, WC, WHR, WHtR and HC but directly with lymphocyte. Significantly, a reciprocal sICAM-1–PON1 relationship was observed in the total population ( r = −0.262, p = 0.015). Conclusion: Utility of sICAM-1 and PON1 as surrogate prognostic biomarkers and putative therapeutic targets in the management of diabetes and MetS is strongly suggested

Cross-sectional correlates of increased IL-18 but reduced fetuin-A and oxytocin with adiposity and blood indices in metabolic syndrome patients with and without prediabetes

Background: Oxytocin (OXT), fetuin-A and interleukin-18 (IL-18) are involved in the development and progression of metabolic syndrome (MetS) and prediabetes (pre/T2DM). Aims, participants and methods: This study aimed to compare and correlate the plasma levels of OXT, fetuin-A and IL-18 with clinical parameters, haematological indices and adiposity indices in Jordanian MetS subjects. In a cross-sectional study, 30 normoglycaemic lean study participants (control), 30 MetS study participants, and 29 MetS pre/T2DM study participants were recruited. Results: Median circulating levels of both OXT and fetuin-A were lower in MetS and MetS pre/T2DM versus control group. OXT (pg/ml; median interquartile range): MetS 1975.4 and MetS pre/T2DM 1403 versus control 4176.6 ( p = 0.009 and p = 0.001, respectively). For fetuin-A (ng/ml), MetS (5784) and MetS pre/T2DM (2154) were lower versus control (6756.3) ( p = 0.040 and p = 0.007, respectively). Neither biomarker was described as substantially different in MetS versus MetS pre/T2DM ( p = 0.071 and p = 0.155, respectively). Conversely, a non-significant increase in IL-18 was observed in the MetS and MetS pre/T2DM groups compared to normoglycaemic lean controls (232 and 287.5, p > 0.05 versus 108 for both). In addition, conicity index (C-index), atherogenicity index (TG-HDL-C), waist to hip ratio, mean platelet volume (MPV; fl) and red cell distribution width (RDW-CV%) in both MetS and MetS pre/T2DM were significantly higher ( p < 0.001) versus controls. However all above MetS-related indices were not ascribed any statistically marked variation in the MetS group when compared to the MetS pre/T2DM group. Both total study pool of recruits’ fetuin-A (Spearman r = – 2.66, p = 0.049) as well as MetS pre/T2DM group IL-18 (Spearman r = 0.380, p = 0.046) were inversely correlated with RDW-CV%. OXT in MetS inversely correlated with waist circumference/hip circumference ratio (Spearman r = −0.387, p = 0.038). No other pronounced associations between biomarkers could be detected in any study arm. Conclusion: These findings substantiate the clinical relevance and significance of OXT, fetuin-A and IL-18 as surrogate screening/prognostic tools and therapeutic targets to predict/prevent metabolic dysregularities and anomalies
