ABSTRACT
Recent data have shown the presence of immunological alterations in adult patients suffering from obsessive-compulsive disorder (OCD). The objective of this study was to examine the possible effects of 12 months of treatment with different serotonergic drugs, such as clomipramine and selective serotonin reuptake inhibitors (SSRIs) on peripheral immunological cells of 18 OCD patients. Both the absolute number and percent of CD4+, CD8+, CD3+, CD19+ and CD56+ cells were measured in peripheral blood before and after treatment by means of a Facstar Flow Sorter apparatus. At baseline, all patients showed a significant increase of CD8+ and decrease of CD4+ lymphocytes when compared with a similar group of healthy control subjects; after the treatment, CD8+ and CD4+ cells, respectively, decreased and increased significantly, and the CD4+/CD8+ ratio increased, when compared with baseline values, in parallel with the clinical improvement. These data suggest that the alterations of immune cells reported in patients with OCD at baseline may be reverted by treatment with SRIs and should be considered a state-dependent marker, perhaps related to a condition of stress.

OBJECTIVE: The aim of this study was to investigate the impact of disability and lifetime subthreshold depressive symptoms on Health-Related Quality of Life (HRQoL) among patients with rheumatoid arthritis (RA). METHODS: Ninety-two subjects with a diagnosis of RA according to the American College of Rheumatology (ACR) criteria were recruited at the Department of Rheumatology of the University Hospital, Pisa, Italy. Participants who met DSM-IV-TR diagnostic criteria for current or previous Axis I disorders were excluded. Assessments of functional status and disability was conducted using both the ACR classification and the Stanford Health Assessment Questionnaire (HAQ). Health-related Quality of Life was assessed using the Medical Outcomes Study Short Form 36 health survey questionnaire (MOS-SF36) and lifetime depressive spectrum symptomatology using the Mood Spectrum Questionnaire, Self-Report version (MOODS-SR). RESULTS: Comparison with MOS-SF36 Italian normative values indicated that RA patients were significantly impaired on mental and physical HRQoL areas. Correlations between MOODS-SR depressive scores and ACR severity (Spearman rho = 0.15, p = 0.07) and HAQ score (Spearman rho = 0.20, p = 0.05) were modest in absolute value and borderline significant. Lifetime mood depressive spectrum was related with impaired HRQoL levels, both in physical (except for bodily pain) and mental (except for social functioning) domains. Associations of mood depressive spectrum and general health, vitality, role emotional and mental health continued to be significant after controlling for functional status, duration of illness, age and gender. CONCLUSIONS: Because lifetime mood depressive symptoms significantly contribute to impairment in HRQoL in RA patients without a past psychiatric history, even after controlling for functional status, duration of illness and demographic characteristics, these symptoms should be assessed for an accurate clinical evaluation and appropriate clinical management of RA patients.
