| Resumen: |
BACKGROUND: Cocaine use disorder (CUD) is a complex health condition, especially when it is accompanied by comorbid psychiatric disorders (dual diagnosis). Dual diagnosis is associated with difficulties in the stratification and treatment of patients. One of the major challenges in clinical practice of addiction psychiatry is the lack of objective biological markers that indicate the degree of consumption, severity of addiction, level of toxicity and response to treatment in patients with CUD. These potential biomarkers would be fundamental players in the diagnosis, stratification, prognosis and therapeutic orientation in addiction. Due to growing evidence of the involvement of the immune system in addiction and psychiatric disorders, we tested the hypothesis that patients with CUD in abstinence might have altered circulating levels of signaling proteins related to systemic inflammation. METHODS: The study was designed as a cross-sectional study of CUD treatment-seeking patients. These patients were recruited from outpatient programs in the province of Malaga (Spain). The study was performed with a total of 160 white Caucasian subjects, who were divided into the following groups: patients diagnosed with CUD in abstinence (N = 79, cocaine group) and matched control subjects (N = 81, control group). Participants were clinically evaluated with the diagnostic interview PRISM according to the DSM-IV-TR, and blood samples were collected for the determination of chemokine C-C motif ligand 11 (CCL11, eotaxin-1), interferon gamma (IFN?), interleukin-4 (IL-4), interleukin-8 (IL-8), interleukin-17? (IL-17?), macrophage inflammatory protein 1? (MIP-1?) and transforming growth factor ? (TGF?) levels in the plasma. Clinical and biochemical data were analyzed in order to find relationships between variables. RESULTS: While 57% of patients with CUD were diagnosed with dual diagnosis, approximately 73% of patients had other substance use disorders. Cocaine patients displayed greater cocaine symptom severity when they were diagnosed with psychiatric comorbidity. Regarding inflammatory factors, we observed significantly lower plasma levels of IL-17? (p DISCUSSION: IL-17?, MIP-1? and TGF? levels are different between the cocaine and control groups, and TGF? levels facilitate the identification of patients with dual diagnosis. Because TGF? reduction is associated with enhanced responses to cocaine in preclinical models, we propose TGF? as a potential biomarker of complex CUD in humans. |
