RESUMO
The adipocytokine leptin is a key mediator of energy homeostasis. Recent papers have suggested that leptin may also have roles in the brain however it is unclear whether leptin is connected to symptoms of mental disorders. In this study, we sought to clarify the relationships between serum leptin level and psychopathology in schizophrenia (SZ) patients. The severity of positive symptoms inversely correlated with the serum leptin levels among SZ patients. There was no correlation between leptin levels and negative symptoms or neurocognition. Our data suggest a role of leptin in SZ positive symptoms.

Epidemiologic studies of autoimmune diseases have not considered them in the aggregate. The objective was to estimate the prevalence of 30 autoimmune diseases separately and in aggregate according to ICD-10 classification. The lifetime prevalence of the entire population of 5,506,574 persons alive in Denmark on October 31, 2006, was estimated by linking records of all visitors to hospitals and specialty clinics via National Patient Registers from January 1, 1977 through October 31, 2006. The prevalences vary from 0.06/1,000 for Pemphigus to 8.94/1,000 for Type 1 diabetes. Nearly 4% of the population had one or more autoimmune disease. The general conclusion is that autoimmune diseases as an aggregate are common.
