Oxidative stress and inflammatory parameters in adult patients presenting with celiac disease
Get PDFCeliac disease is a chronic small intestinal inflammatory condition caused by an inappropriate immune response to gluten of wheat, rye and barley, with a prevalence of about 1: 100 in the Caucasian population when occurs a inflammatory response and seems to involve high levels of interleukins. Objective: Determine the presence of oxidative stress and inflammation in the gut of patients with CD. Methods: Transversal study that included patients undergoing upper gastrointestinal (GI) endoscopy was performed. The study population consisted 24 cases and 26 controls. The duodenal levels of protein carbonyls, thiobarbituric acid reactive species (TBARS), as well as catalase (CAT), superoxide dismutase (SOD) activities were measured. Gut levels of interleukin (IL) 6, 10 and 8 were also determined. The Marsh classification was recorded and used as a parameter of disease severity. Results: Both IL-6 and IL-10, but not IL8, were increased in CD patients when compared to healthy individuals. Oxidative damage parameters were increased while antioxidant defenses were decreased in our sample. Both IL6 levels and SOD activity were related to Marsh score. Conclusions: Different markers of inflammation and oxidative stress are altered in the gut of CD patients, and some of them are related to disease severity
Evaluation of Serum Cytokines Levels and the Role of Cannabidiol Treatment in Animal Model of Asthma
No full textAsthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways. Studies have demonstrated the presence of T-helper 2 lymphocytes in the lung of patients with asthma. These cells are involved in cytokine production that regulates immunoglobulin synthesis. Recognizing that T cell interaction with antigens/allergens is key to the development of inflammatory diseases, the aim of this study is to evaluate the anti-inflammatory potential of cannabidiol (CBD) in this setting. Asthma was induced in 8-week-old Wistar rats by ovalbumin (OVA). In the last 2 days of OVA challenge animals received CBD (5 mg/kg, i.p.) and were killed 24 hours after. The levels of IL-4, IL-5, IL-13, IL-6, IL-10, and TNF-α were determinate in the serum. CBD treatment was able to decrease the serum levels of all analyzed cytokines except for IL-10 levels. CBD seems to be a potential new drug to modulate inflammatory response in asthma
