We investigated and compared the results of treating the chronic hepatitis C (HCV) infection of different groups of psychiatric-risk patients and controls with pegylated interferon alpha (pegIFN-␣) plus ribavirin. Seventy patients were prospectively screened for psychiatric disorders. Seventeen patients without psychiatric diseases or drug addiction (controls), 22 patients with psychiatric disorders, 18 patients who had received methadone substitution treatment and 13 patients who were former drug users were treated with pegIFN-␣ plus ribavirin. Sustained virological response (SVR), adherence, and psychiatric side effects (using the MontgomeryAsberg Depression Rating Scale and the Brief Psychiatric Rating Scale) in the groups were compared. An SVR was found in 58.6% of all patients: 58.8% of the controls, 50% of psychiatric patients, 72.2% of methadone patients, and 53.8% of former drug users. Methadone-substituted patients and former drug users had significantly higher dropout rates. Scores for neither depressive nor psychotic symptoms differed significantly between groups during treatment. However, the controls had lower pretreatment scores, followed by a significant higher increase to maximum scores. A stepwise logistic regression model showed that only genotype, not group (control, psychiatric, methadone, or former drug abuse), type of psychiatric diagnosis (affective disorder, personality disorder, or schizophrenic disorder), depression scores before and during treatment, change in depression score, antidepressive treatment, sex, or liver enzymes before treatment, was associated with SVR. Conclusion: In an interdisciplinary treatment setting psychiatric diseases and/or drug addiction did not negatively influence psychiatric tolerability of and antiviral response rate to HCV treatment with pegIFN-␣ and ribavirin. ( I t is estimated that 170 million people worldwide are infected with the hepatitis C virus (HCV). Although the prevalence in the general population ranges between 1% and 2.4%, 1,2 the prevalence of HCV infection in patients with a chronic psychiatric disorder has been found to be significantly higher-between 6.8% and 8.5%. 3,4 Moreover, between 60% and 98% of intravenous drug users are chronically infected with HCV. [5][6][7] Interferon alpha (IFN-␣) is still the only effective treatment for chronic hepatitis C infection. In 1998, 2 studies showed that a combined regimen of IFN-␣ with ribavirin increased the sustained virological response (SVR) from 10% to 40%. 8,9 The development of pegylated interferons (pegIFN alpha-2a and pegIFN alpha-2b), characterized by a significantly longer half-life that allowed subcutaneous injection only once a week, further significantly improved therapeutic outcome when used in treatment in combination with ribavirin. 10-12 SVR rates between 51% and 82% have been reported, depending on the virus genotype. 10,11 Antiviral treatment of chronic hepatitis C with IFN-␣ is associated with several neuropsychiatric side effects such as fatigue, anhedonia, depression, irritab...
Over the course of the past decade, the acceptance of several second-generation antipsychotics (SGAs) as effective medication for the treatment of schizophrenia has led to some changes. SGAs have a lower risk of inducing extrapyramidal side effects and tardive dyskinesia compared with first-generation antipsychotics, and have been said to be more successful in long-term treatment and tolerability. They also significantly improve the quality of life of schizophrenic patients. However, during treatment with SGAs other adverse effects can occur, such as weight gain, metabolic changes, sexual dysfunction and QTc-prolongation, significantly affecting the patient's physical health. Consequently, these side effects might be the reason that a high proportion of patients discontinue treatment with SGAs. Thus, from the authors' view, optimising individualised treatment implies increasing the efficacy of current schizophrenia drugs. This can be achieved by finding clinical or pharmacogenetic predictors for the most appropriate drug or drug combination, and by improving side-effect management in combination with non-pharmacological interventions in order to increase patients' quality of life and treatment compliance, possibly resulting in a better long-term outcome.
The purpose of the present study was to evaluate the incidence, spectrum and extent of psychiatric symptoms in patients with malignant melanoma (MM) before and during adjuvant treatment with interferon-alpha (IFN-alpha). 850 patients with cutaneous MM of > or =1.5 mm tumor thickness received standard low-dose IFN-alpha 2a in this prospective multicenter trial of the Dermatologic Cooperative Oncology Group (DeCOG). Psychiatric symptoms were evaluated at baseline and after 3, 6, and 12 months with the Beck Depression Inventory (BDI) and the Symptom Check List 90-Revised (SCL 90-R). In all, 282 patients completed all questionnaires. Mean BDI depression scores increased significantly during the first 6 months of IFN-alpha treatment (P < or =0.001), followed by a mild but not significant decrease. Also mean SCL 90-R scores increased significantly during the first 3 months of adjuvant treatment with IFN-alpha (P< or =0.001) and remained elevated until month 12 (P< or =0.001). Only 5% developed BDI scores >10, indicating a clinically significant depressive syndrome and only 1.4% reached a BDI score > or =18, indicating a moderate to severe depressive syndrome. Patients, who dropped-out early from psychiatric reasons, had significantly increased BDI and SCL-90R scores at baseline. Women scored higher in both scales before and during treatment if compared with men. In conclusion, adjuvant treatment with IFN-alpha was associated with a significant increase of BDI- and SCL 90-R scores. A higher pretreatment depression score was found to be a risk factor for an early drop-out during therapy. Pretreatment screening and an interdisciplinary care of the patients is recommended.
