Randomized Controlled Trial
Activation of the interleukin-34 inflammatory pathway in response to influenza A virus infection.
Interleukin 34 (IL-34) is a newly recognized cytokine that functions similarly to macrophage colony-stimulating factor. This study investigated the mechanism by which IL-34 is produced in response to exogenous pathogen infections in humans. The results showed that the IL-34 levels were higher in the serum and peripheral blood mononuclear cells (PBMCs) from 155 influenza A virus (IAV)-infected patients than in those from 145 healthy individuals. ⋯ This result showed that the production of IL-22 and IL-34 is both from the same and different subset of cells, which indicated that the regulatory mechanism of IL-22/IL-34 is through the autocrine or paracrine systems. In conclusion, IL-34 is induced by IL-22 in the inflammatory cascade in response to IAV infection. Therefore, IL-34 is a promising target for the screening of anti-inflammatory medicines.

Comparative Study Clinical Trial
Plasma levels of C1q/TNF-related protein 1 and interleukin 6 in patients with acute coronary syndrome or stable angina pectoris.
C1q/TNF-related protein 1 (CTRP-1), a novel adipocyte factor, may participate in the mechanisms of metabolism and inflammation. Interleukin 6 (IL-6) is a proinflammatory cytokine that is correlated with the severity of coronary heart disease (CHD). In this study, we focused on the levels of CTRP-1 and IL-6 in patients with CHD. ⋯ The variation of plasma CTRP-1 and IL-6 concentrations may play an important role in reflecting the degree of inflammation in CHD and the severity of coronary arterial atherosclerosis. This potential suggests that evaluating CTRP-1 and IL-6 in combination may aid in predicting the occurrence of CHD.

Morbidities related to atherosclerosis, such as acute coronary syndrome (ACS), remain the leading cause of mortality. Axl is a receptor tyrosine kinase that is expressed in mammalian vascular and immune cells. Axl signaling is involved in the regulation of the inflammatory response. A considerable amount of evidence indicates that inflammation is responsible for the development of atherosclerosis in patients with ACS. ⋯ Serum levels of sAxl correlate to inflammatory biochemical markers. These findings demonstrate for the first time that sAxl does have a role in ACS, presumably connected to the inflammation.

Reports on adherence among patients with rheumatoid arthritis (RA) in Egypt and the Middle East region are lacking. This study aimed to measure adherence to treatment among a sample of patients with RA at Ain Shams University Rheumatology outpatient clinic and to assess factors affecting it. ⋯ Higher adherence was associated with more positive beliefs on medication, greater satisfaction with health care and less disease activity.
