Differential flow cytometric detection of intracellular cytokines in peripheral and peritoneal mononuclear cells of women with endometriosis

OBJECTIVE: The pathogenesis of endometriosis is related to functional changes in CD3+ and CD14+ cells observed both at the local and systemic level. Here we investigated whether, and if so, how the body compartment influences cytokine expression in stimulated peritoneal and peripheral CD3+ and CD14+ cells of women with endometriosis. STUDY DESIGN: Isolated peripheral blood (PB) and peritoneal fluid (PF) mononuclear cells from women with endometriosis were cultured under non-adherent conditions and stimulated with PMA and ionomycin for 6h to induce intracellular cytokine synthesis of TNF-alpha, IFN-gamma, and IL-8 by CD3+ cells or with LPS for 9h to produce TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 by CD14+ cells. RESULTS: The percentages of positive CD3+ cells stained for TNF-alpha and IFN-gamma were significantly higher and those stained for IL-8 were significantly lower in PF compared with PB, this being independent of the stage of endometriosis. In contrast, the percentages of CD14+ cells producing TNF-alpha, IL-6, IL-10, MCP-1, and IL-8 were significantly higher in PB than PF of women with endometriosis. CONCLUSIONS: Monocytes/macrophages and lymphocytes derived from the peripheral and peritoneal compartments of women with endometriosis differentially respond to stimulated cytokine synthesis induction. However, it is difficult to state whether the observed phenomenon is more related to body compartment influence per se or to the presence of endometriosis.     

Analysis of steps adapted protocol in cardiac rehabilitation in the hospital phase

Objective

To analyze a cardiac rehabilitation adapted protocol in physical therapy during the postoperative hospital phase of cardiac surgery in a service of high complexity, in aspects regarded to complications and mortality prevalence and hospitalization days.

Methods

This is an observational cross-sectional, retrospective and analytical study performed by investigating 99 patients who underwent cardiac surgery for coronary artery bypass graft, heart valve replacement or a combination of both. Step program adapted for rehabilitation after cardiac surgery was analyzed under the command of the physiotherapy professional team.

Results

In average, a patient stays for two days in the Intensive Care Unit and three to four days in the hospital room, totalizing six days of hospitalization. Fatalities occurred in a higher percentage during hospitalization (5.1%) and up to two years period (8.6%) when compared to 30 days after hospital discharge (1.1%). Among the postoperative complications, the hemodynamic (63.4%) and respiratory (42.6%) were the most prevalent. 36-42% of complications occurred between the immediate postoperative period and the second postoperative day. The hospital discharge started from the fifth postoperative day. We can observe that in each following day, the patients are evolving in achieving the Steps, where Step 3 was the most used during the rehabilitation phase I.

Conclusion

This evolution program by steps can to guide the physical rehabilitation at the hospital in patients after cardiac surgery.     

The Importance of Interleukin 18, Glutathione Peroxidase, and Selenium Concentration Changes in Acute Pancreatitis

Cytokinemia and oxidative stress are important factors responsible for an inadequate immune response in the early course of acute pancreatitis (AP). The aim of the study was to evaluate the profiles of interleukin 18 (IL-18), glutathione peroxidase (GPx), and selenium concentrations in serum with respect to AP severity and to study the relationships between these parameters and recognized prognostic indicators of AP severity. Prospective clinical analyses were performed on 61 patients with mild and severe forms of AP and for 15 healthy volunteers. In both forms of AP severity, the IL-18 concentration in the serum was significantly higher than in healthy controls. In the severe form of AP, the IL-18 concentration was the highest and exceeded significantly the values recorded on the 1st, 2nd, 3rd, 5th, and 10th days of mild AP. A significantly lower GPx concentration in the serum was recorded in severe AP compared to the mild form and in the control group. There was a significantly lower selenium concentration in the severe form of AP. Significant correlations between GPx and selenium, between IL-18 and GPx, and between IL-18 and selenium were recorded. The ROC analysis shows a high prognostic accuracy of IL-18 and GPx concentrations in the determination of AP severity. IL-18 is released early in the course of AP and may be a key immunomodulator of the inflammatory response in the severe form of this disease. Low GPx and selenium concentrations in severe AP reflect the lower antioxidative ability in this form of AP. IL-18 and GPx may represent new indicators of AP severity.     

Amiodarone induced pneumonitis and hyperthyroidism: case report

Amiodarone is a highly effective antiarrhythmic agent used in life-threatening ventricular and supraventricular arrhythmias. Its long-term use may however lead to several adverse effects, including corneal deposits, liver and thyroid gland dysfunction, lung lesions, bone marrow injury, skin lesions, or neurological abnormalities. The article presents the case of a 56-year-old man with a history of a stroke, who after a few days of amiodarone therapy for an episode of atrial fibrillation was diagnosed with amiodarone-induced hyperthyroidism and interstitial pulmonary lesions. Clinical and laboratory symptoms of hyperthyroidism and radiographic signs of pulmonary involvement did not occur until several weeks after discontinuation of amiodarone therapy. Differential diagnosis of causes of hyperthyroidism and diseases causing nodular pulmonary lesions did not demonstrate any other pathologies. Empirical antibiotic therapy and administration of thiamazole and high doses of propranolol failed to improve the patient's clinical status. It was not until thiamazole was given in combination with glucocorticosteroids, when a slow relief of hyperthyroidism symptoms and resolution of radiographic pulmonary signs were observed. Based on the presented case, the risk of appearance of 2 serious concomitant adverse effects was demonstrated, even following a short-term amiodarone therapy. This paper also contains an overview of adverse effects which may be encountered during or after therapy with this effective antiarrhythmic agent. It was emphasized how important it is to select patients appropriately, and to monitor potential adverse effects during amiodarone therapy.
