Patten and Barbui [1] have performed a singular service to the profession by carrying out a systematic review on drug-induced depression. Their recommendations are based on studies that have randomly allocated patients into study and control groups, and the authors have provided an adequate justifi cation for this being the most scientifi c approach. This letter is to point out that the authors have erroneously designated a study as a randomized controlled trial. The authors state that… Expand
Association of chronic hepatitis C with major depressive disorders: irrespective of interferon-alpha therapy

Interferon Alpha-Induced Depression in Chronic Hepatitis C Patients: Comparison between Different Types of Interferon Alpha
TLDR
A very careful selection of hepatitis C patients is required before starting IFN alpha therapy, as leukocyte IFNAlpha seemed to present a more elevated tolerability than other IFNalpha types available for clinical practice. Expand
The phenomenology and treatment of interferon-induced depression.
TLDR
Review of the literature suggests that symptoms of depression induced by IFN therapy, in particular IFN-alpha therapy, are common and can limit the treatment utility, often necessitating discontinuation ofIFN therapy or the use of psychopharmacologic agents. Expand
Drug-Induced Depression: A Systematic Review to Inform Clinical Practice
TLDR
Evidence was found linking corticosteroids, interferon-α, interleukin-2, gonadotropin-releasing hormone agonists, mefloquine, progestin- releasing implanted contraceptives and propranolol to the etiology of atypical depressive syndromes. Expand
Depression during pegylated interferon-alpha plus ribavirin therapy: prevalence and prediction.
TLDR
Development of moderate to severe depressive symptoms occurred frequently during PEG IFN/ribavirin treatment and was predicted by baseline depression scores and higher doses of ribavirin, but only through association with elevated baseline depression status. Expand
Neuropsychiatric Adverse Effects of Interferon-α
Recombinant preparations of the cytokine interferon (IFN)-α are increasingly used to treat a number of medical conditions, including chronic viral hepatitis and several malignancies. AlthoughExpand
Neuropsychiatric adverse effects of interferon-alpha: recognition and management.
TLDR
Depression-specific symptoms are highly responsive to serotonergic antidepressants, whereas neurovegetative symptoms are significantly less responsive to these agents, and these symptoms may be more effectively treated by agents that modulate catecholaminergic functioning. Expand
Early increase in vegetative symptoms predicts IFN-α-induced cognitive-depressive changes
TLDR
During IFN-α treatment, vegetative symptoms of depression appear earlier than, and are predictive of, their cognitive counterparts, which suggests that low mood state may in part be driven by the increase in early vegetative-depressive symptoms in the course of IFn-α-induced immune activation.
