Filter by:This is an observational study involving chart review of patients seen in the bariatric clinic since 2012 at The Ohio State University (OSU). Obese patients will be divided into two groups according to their metabolic profile (healthy vs unhealthy). The assignment to each group will be determined by the presence of diagnosis of hypertension, diabetes mellitus and/or dyslipidemia. The presence of at least 2 diagnoses will be defined as metabolically unhealthy. Then, each group will be divided based on the presence of Obstructive Sleep Apnea diagnosis. All data will be collected through a review of the patient's electronic medical record from the bariatric clinic database (the investigators will collect variables as age, gender, race, BMI, smoking status, the presence of diagnosis as Obstructive sleep apnea, hypertension, diabetes, hyperlipidemia). The investigators will analyze that data and establish if there is any correlation between sleep apnea and the subjects' metabolic profile.
The pathophysiological mechanisms explaining the association between psoriasis and type 2 diabetes are largely unknown but it has been hypothesized that systemic inflammation found in both psoriasis and type 2 diabetes might play a role. In a recent study hyperinsulinaemic euglycaemic clamps were performed and it showed that normal glucose-tolerant patients with moderate to severe psoriasis had lower whole-body insulin sensitivity during insulin stimulation compared to healthy matched controls. Thus, the increased risk of type 2 diabetes in patients with psoriasis appears to include defects in the glucose metabolism linked to psoriasis itself. However, the methods applied did not allow a detailed characterization of the metabolism in patients with psoriasis. Tracer technique combined with indirect calorimetry has never been applied to study hepatic and whole body insulin sensitivity, and glucose and fat oxidation, during basal conditions or during insulin stimulation in patients with psoriasis. Aim of study: The aim of this study is to investigate hepatic and whole body insulin sensitivity and glucose and fat oxidation during both basal and insulin-stimulated conditions in patients with psoriasis.
