Toll-Like Receptor (TLR) 1, 2, and 6 Gene Polymorphisms Support Evidence of Innate Immune Factors in Schizophrenia.

Introduction: Schizophrenia is a complex psychiatric disorder with an important genetic contribution. Immunological abnormalities have been reported in schizophrenia. Toll-like receptor (TLR) genes play an important role in the activation of the innate immune response, which may help to explain the presence of inflammation in people with this disorder. The aim of this study was to analyze the association of TLR1, TLR2, and TLR6 gene polymorphisms in the etiology of schizophrenia. Methods: We included 582 patients with schizophrenia and 525 healthy controls. Genetic analysis was performed using allelic discrimination with TaqMan probes. Results: We observed significant differences between patients and controls in the genotype and allele frequencies of TLR1/rs4833093 (χ2 = 17.3, p = 0.0002; χ2 = 15.9, p = 0.0001, respectively) and TLR2/rs5743709 (χ2 = 29.5, p = 0.00001; χ2 = 7.785, p = 0.0053, respectively), and in the allele frequencies of TLR6/rs3775073 (χ2 = 31.1, p = 0.00001). Finally, we found an interaction between the TLR1/rs4833093 and TLR2/rs5743709 genes, which increased the risk of developing schizophrenia (OR = 2.29, 95% CI [1.75, 3.01]). Discussion: Our findings add to the evidence suggesting that the activation of innate immune response might play an important role in the development of schizophrenia.

Tratamiento de la esquizofrenia en México: recomendaciones de un panel de expertos.

La esquizofrenia es una enfermedad compleja que actualmente no tiene cura. Existen, sin embargo, numerosas terapias que, solas o en combinación, son eficaces para tratar los síntomas de la enfermedad y mantenerla bajo control. La elección del tratamiento debe ser siempre individualizada, y basarse en la presentación clínica de la enfermedad, el estado general del paciente y la eficacia del fármaco, si bien hay que considerar también el costo y el acceso a servicios y al fármaco, que en México tiene algunas limitaciones. Un panel de 12 expertos mexicanos se reunió de forma virtual para revisar los últimos datos publicados y establecer unas recomendaciones de tratamiento en México, basadas en la evidencia, que garanticen una atención médica integral, homogénea, eficiente y con calidad.Schizophrenia is a complex illness that currently has no cure.

Abstract Schizophrenia is a complex illness that currently has no cure. There are, however, numerous therapies that, alone or in combination, are effective in treating the symptoms of the disease and keeping it under control. The choice of treatment must always be individualized, and based on the clinical presentation of the disease, the general condition of the patient and the efficacy of the drug, although the cost and access to services and to the drug must also be considered, as in Mexico it has some limitations. A panel of 12 Mexican experts met virtually to review the latest published data and establish evidence-based treatment recommendations in Mexico that guarantee comprehensive, homogeneous, efficient, and quality medical care.
