The specific associations between antidepressant treatment and alterations in the levels of cytokines remain to be elucidated. In this study, we aimed to explore the role of IL-2, IL-4, IL-12, TNF-α, TGF-β1, and MCP-1 in major depression and to investigate the effects of sertraline therapy. Cytokine and chemokine levels were measured at the time of admission and 8 weeks after sertraline treatment. Our results suggest that the proinflammatory cytokines (IL-2, IL-12, and TNF-α) and MCP-1 were significantly higher, whereas anti-inflammatory cytokines IL-4 and TGF-β1 were significantly lower in patients with major depression than those of healthy controls. It seems likely that the sertraline therapy might have exerted immunomodulatory effects through a decrease in the proinflammatory cytokine IL-12 and an increase in the anti-inflammatory cytokines IL-4 and TGF-β1. In conclusion, our results indicate that Th1-, Th2-, and Th3-type cytokines are altered in the depressed patients and some of them might have been corrected by sertraline treatment.

Mirtazapine augmentation is a good choice for the treatment of SSRI-induced sexual dysfunction, and the results are typically seen later after 4-8 weeks.

There has been no follow-up study regarding the effect of alexithymic features on antidepressant treatment. This study was planned to observe whether alexithymia effects short-term treatment outcome in depression. The study included 32 alexithymic and 33 nonalexithymic outpatients with major depression. Depression was assessed on the basis of the Structured Clinical Interview for DSM-IV (SCID-I). Level of depression was measured using the 17-item Hamilton Rating Scale for Depression (HAM-D). Alexithymia was screened using the Turkish version of Toronto Alexithymia Scale (TAS-20). All patients received 20 mg/d paroxetine for 10 weeks. Alexithymic and nonalexithymic patients were compared on the HAM-D scores, TAS-20 scores, and rate of response to antidepressant medication. The rate of responders, defined by a reduction of >50% from baseline in HAM-D total score, was 21.9% in the alexithymic group and 54.5% in the nonalexithymic group. Changes in the HAM-D scores were significantly correlated with the TAS-20 scores. TAS-20 scores dropped below 61 in only 31.2% of the alexithymic patients, and 68.8% of patients remained alexithymic. Whereas 50% of patients whose TAS-20 scores dropped below 61 responded to antidepressant medication, this rate was only 9.1% among patients who remained alexithymic. These findings indicated that the stability of alexithymic features had a negative effect on antidepressant treatment in depression.

The transition metal zinc is an essential element for normal development and function of biological systems including the central nervous system (CNS). Zinc may be an important trace element for the etiology and symptoms of subgroups of autistic children because it is an essential catalytic or structural element of many proteins and important for neural activity and the control of neuronal death. The aim of this study was to evaluate zinc status in children with autistic disorder. Plasma, erythrocyte, and hair zinc levels were measured by atomic absorption spectrophotometry in the 45 and 39 autistic children, respectively. Forty-one healthy children 3 in the same age group were selected as controls. Plasma and erythrocyte zinc levels in the autistic children were found to be significantly lower than normal (P < 0.05). The mean hair zinc level of the patients was also low when compared with that obtained from normal Turkish children. These results may indicate chronic zinc deficiency or metabolic abnormality of zinc in autistic children. Further studies are required to clarify underlying mechanisms.

There is no proven effective treatment for tardive dyskinesia (TD). However, clozapine has been reported to be effective in suppressing TD symptoms. In this article, we report a TD case who received clozapine. The patient recovered from TD symptoms with a dose of 450 mg/day clozapine. At the end of the first year, clozapine was decreased to a dose of 250 mg/day and TD symptoms re-emerged.
