This study examined the adiponectin and leptin levels and insulin resistance (IR) in patients with inflammatory bowel disease (IBD) and the associations between these factors and IBD characteristics. Fasting serum leptin, adiponectin, glucose, and insulin levels, as well as inflammatory parameters, were measured in 105 patients with IBD (49 patients with Crohn’s disease [CD], 56 patients with ulcerative colitis [UC]) and 98 healthy controls [HC]. IR was evaluated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). Disease activity and severity in patients with UC were evaluated using the Truelove–Witts index, and patients with CD were evaluated using the Crohn’s Disease Activity Index. Serum adiponectin levels were found to be significantly lower in patients with CD and UC (p<0.001). Serum leptin levels were also found to be significantly higher in both the UC and CD groups (p<0.001). When HOMA-IR levels were compared, no significant difference was detected for either the CD or UC groups compared with the controls. In conclusion, it was shown that leptin levels increased and adiponectin levels decreased in patients with IBD, which is thought to be related to chronic inflammation. The effects of adipocytokines in patients with IBD with inflammatory and metabolic processes need to be investigated in further broader studies.

Mortality from cardiovascular disease has been found to be increased in patients with systemic lupus erythematosus (SLE). Coronary flow reserve (CFR) measurement is used both to assess epicardial coronary arteries and to examine the integrity of coronary microvascular circulation. Oxidative stress, enhancing modification of plasma lipids, is also associated with atherosclerotic events in lupus patients. Impairment of CFR and TAS has been shown to be an early manifestation of coronary atherosclerosis. Forty patients with SLE and 33 healthy volunteers were included in this study. Echocardiographic examination included left ventricular myocardial velocity measurements and coronary flow reserve (CFR) measurement. Serum total antioxidant status levels (TAS) also were measured using TAS kit. Lateral myocardial early peak velocity (Em) and lateral Em/Am ratio did not differ between the groups, but lateral myocardial atrial peak velocity (Am) was significantly higher in SLE group than the control group. Baseline coronary diastolic peak flow velocity (DPFV) of left anterior descending was similar in both the groups. However, hyperemic DPFV and CFR (2.50 ± 0.42 vs. 3.09 ± 0.45, P < 0.0001) were significantly lower in the SLE group than in the control group. CFR significantly and inversely correlated with CRP and significantly correlated with TAS. Subclinical coronary microvascular dysfunction can occur in SLE patients without traditional cardiovascular risk factors, probably associated with underlying inflammation and impairment of TAS.

Women with a GDM history may be at more risk regarding coronary microvascular dysfunction compared to the healthy ones.

Although the number of patients included in this study is limited, high EFT results may indicate presence of atherosclerosis in women with previous GDM.
