Major depressive disorder (MDD) is a debilitating disorder and its pathophysiology is associated with deregulation of the immune system. We investigated the changes in circulating levels of proinflammatory cytokines (specifically IL-6 and TNF-α) measured by the ELISA kit in two psychotherapeutic interventions for MDD: Narrative Cognitive Therapy (NCT) and Cognitive Behavioral Therapy (CBT). This is a randomized clinical trial including 97 individuals (18 to 29years-old) with MDD. In CBT there was a significant difference in serum levels of IL-6 and TNF-α, therefore indicating that CBT was more effective than NCT on serum levels proinflammatory cytokines.
