The objective of this study was to investigate whether serum cytokine levels correlate with depression and anxiety in colorectal cancer (CRC) patients. Twenty patients hospitalized for surgical resection of CRC were included in the study group and twenty healthy volunteers comprised the control group. Depression and anxiety were analyzed using the Hospital Anxiety and Depression Scale (HADS), and serum levels of IL-1β, IL-6, IL-8, IL-10, IL-12, TNF-α, and TGF-β were measured by Cytometric Bead Array. We found that more than half of CRC patients presented clinically significant levels of anxiety or depression, and 65% of them manifested a combination of severe anxiety and depression. CRC patients had increased serum levels of IL-1β, IL-6, IL-8, and TNF-α but lower IL-10 concentrations. Correlation analysis between HADS score and cytokine levels revealed a positive association of anxiety and/or depression with IL-1β, IL-6, IL-8, and TNF-α and a negative correlation with IL-10. These results indicate that circulating proinflammatory cytokines are involved in the pathophysiology of anxiety and depression in CRC patients. A better understanding of the molecular mechanisms involved in these psychological disorders will allow the design of therapeutic interventions that lead to an improved quality of life and overall survival of CRC patients.
Resumo A gastrite isquêmica é uma doença rara, podendo ocorrer por insuficiência vascular focal ou sistêmica. Essa condição é raramente vista na prática médica devido à vasta rede colateral arterial do estômago pelo tronco celíaco e mesentérica superior. A apresentação clássica da isquemia crônica é formada pela tríade de dor pós-prandial, perda de peso e sopro abdominal. A intervenção está indicada naqueles pacientes sintomáticos, sendo o tratamento endovascular uma alternativa à cirurgia em pacientes com alta comorbidade, tendo bons resultados. Reportamos um caso de gastrite isquêmica grave com úlceras e sangramento que foi causado por isquemia mesentérica crônica, em uma paciente de 71 anos, com oclusão do tronco celíaco e mesentérica inferior, além de estenose crítica da superior. O diagnóstico foi confirmado por exame de imagem, e a paciente foi submetida a tratamento endovascular. Trata-se de uma condição rara de diagnóstico e tratamento desafiadores, a qual requer uma equipe multidisciplinar para o manejo adequado.
