Effects of iron manipulation on trace elements level in a model of colitis in rats

AIM: Trace elements (TE) metabolism is altered in inflammatory bowel diseases. TE (zinc and copper) are constituents of antioxidant enzymes. Iron is involved in the pathogenesis of chronic inflammation. The aim was to evaluate zinc and copper status and the effects of iron manipulation in experimental colitis. METHODS: Twenty-four male Sprague-Dawley rats were divided into four groups: standard diet, iron-deprived diet, iron-supplemented diet, and sham-treated controls. Macroscopic damage was scored. DNA adducts were measured in the colon. Liver and colonic concentration of TE were measured. RESULTS: Macroscopic damage was reduced in iron-deprived groups and increased in iron-supplemented rats. Damage to the DNA was reduced in iron-deprived groups and increased in iron-supplemented groups. Liver and colonic iron concentrations were reduced in iron-deprived and increased in iron-supplemented rats. Liver zinc concentration was reduced after supplementation whereas colonic levels were similar in controls and treated rats. Liver copper concentration was reduced in all the colitic groups except in the iron-supplemented group whereas colonic concentration was increased in iron-deprived rats. CONCLUSION: Iron deprivation diminishes the severity of DNBS colitis while supplementation worsens colitis. Zinc and copper status are modified by iron manipulation.     

Does current treatment of cardiogenic shock complicating the acute coronary syndromes comply with guidelines?

Background

The purpose of our study was to evaluate the implementation of guidelines for the treatment of cardiogenic shock (CS) complicating the acute coronary syndromes (ACS).

Methods and Results

Of the 10 136 patients in the Euro-Heart-Survey-ACS with complete data, CS occurred in 549 (5.4%), of whom 28.6% had CS upon presentation. We examined the use of coronary angiography (CA), percutaneous (PCI) and surgical (CABG) revascularization, and intra-aortic balloon counterpulsation (IABP) among ACS patients with and without CS. During the hospital course, there were no significant differences between patients with and without CS in referral to CA (52.4% vs 53.3%, respectively) or CABG (4.4% vs 4.5%), but CS patients were more likely to undergo IABP (17.7% vs 0.8%, P < .001) and PCI (40.8% vs 31.8%, P < .001), especially younger (<75 years) patients (52.2% vs 31.8%, P < .001). A similar trend was observed when comparing ST-elevation-ACS patients with (368 [8.5%]) and without CS (3945): CA (58.1% vs 56.2%), CABG (3.6% vs 3.3%), IABP (20.0% vs 0.9%, P < .01), and PCI (47.3% vs 40.6%, P < .01; 54.4% vs. 44.6% for patients <75 years, P < .003). Of the 94 ST-elevation-ACS patients presenting with CS, only 39 (41.4%) received any reperfusion treatment, more often fibrinolysis (64.1%). The in-hospital mortality was 52.1% for all CS pts vs 2.0% for all others (P < .001).

Conclusions

Our contemporary survey demonstrates prohibitively-high mortality rates among ACS patients complicated by CS and poor implementation of recent guidelines advocating an aggressive invasive approach, including low rates of revascularization and IABP. Improved adherence to the guidelines pertaining to ACS patients developing CS may hopefully improve outcomes.     

Systemic inflammatory diseases and silicone breast prostheses: report of a case of adult still disease and review of the literature

There has been a debate about the possibility of a link between silicone breast implants and the onset of systemic connective tissue diseases (eg, scleroderma, systemic lupus erythematosus, rheumatoid arthritis) and other inflammatory pathologies, such as silicone implant associated syndrome and adult Still disease. We report a case of adult Still disease in a patient with a silicone gel breast implant. The disease regressed with steroidal treatment, and the patient is now no longer steroid-dependent, although the implant is still in place.     

Ebstein disease and pregnancy

Three patients with Ebstein's disease became pregnant 11 times, 6 of which ended as spontaneous abortion, 2 newborn deaths and 3 successful term pregnancies. Ventricular overloading, arterial hypoxemia and arrhythmias are the major physiopathologic determinants. The ventricular overloading is the most important risk factor for the mother, so as the hypoxemia and the arrhythmias for the fetus. Pregnancy in these patients must be considered at high risk, and a close cardiologic assess with continuous hormonal controls of fetus maturity during the last trimester should be done. A team including obstetricians, cardiologists and anesthesiologists is suggested for the care of these patients in the view of a successful outcome.
