Antidepressants are effective in treating interferon-α/ribavirin (IFN-α/RBV)-associated depression during or after treatment of chronic hepatitis C (CHC). Whether antidepressant prophylaxis is necessary in this population remains under debate.
Comprehensive searches were performed in Medline, Embase, Cochrane Controlled Trials Register and PubMed. Reference lists were searched manually. The methodology was in accordance with the 2009 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Statement.
We identified six randomized, double-blind, placebo-controlled trials involving 522 CHC patients treated with pegylated (PEG)-IFN-α plus RBV. The antidepressants used were escitalopram, citalopram, and paroxetine, which are selective serotonin reuptake inhibitors (SSRIs). The rates of depression (17.9% vs. 31.0%, P = 0.0005), and rescue therapy (27.4% vs. 42.7%, P<0.0001) in the SSRI group were significantly lower than those in the placebo group. The rate of sustained virological response (SVR) (56.8% vs. 50.0%, P = 0.60) and drug discontinuation (18.7% vs. 21.1%, P = 0.63) in the SSRI group did not differ significantly to those in the placebo group. In terms of safety, the incidence of muscle and joint pain (40.8% vs. 52.4%, P = 0.03) and respiratory problems (29.3% vs. 40.1%, P = 0.03) were lower, but the incidence of dizziness was significantly higher (22.3% vs. 10.2%, P = 0.001) in the SSRI group.
Prophylactic SSRI antidepressants can significantly reduce the incidence of PEG-IFN-α/RBV-associated depression in patients with CHC, with good safety and tolerability, without reduction of SVR.

    ABSTRACT: Background: Depression related to interferon-alpha (IFN-α) is common, may reduce adherence, and can be treatment limiting. HIV-HCV coinfected persons experience lower sustained virologic response rates and commonly have psychiatric comorbidities, thus they may benefit from prevention of depression. Objective: The aim of the study was to determine whether prophylactic citalopram can increase HCV treatment adherence and reduce the incidence of moderate depression in HIV-HCV coinfected patients initiating PEG-IFN-α/ribavirin therapy. Methods: This was an investigator-initiated Canadian multicenter randomized, double-blind placebo-controlled trial. HIV-HCV coinfected patients were randomized in a 1:1 ratio to receive citalopram or placebo 3 weeks prior to starting PEG-IFN-α2b/ribavirin, stratified by study center and HCV genotype. The protocol design permitted the comparison of prophylaxis with the treatment of emergent depression. The primary outcomes were adherence (assessed through questionnaire and returned medication) and time to moderate depression measured by Beck Depression Inventory-II (BDI- II) score greater than 15, confirmed 2 weeks apart. Results: Seventy-six patients (36 citalopram/40 placebo) were randomized. Overall adherence was high, ranging from 95% (week 12) to 91% (week 48). There was no difference between arms with respect to mean or median adherence at any study time point. Cumulative incidence of moderate depression did not differ significantly by group (log rank P = .32). The hazard ratio for moderate depression was 0.81 (95% CI, 0.26 to 2.54) for citalopram compared with placebo when adjusted for baseline BDI-II score. Conclusions : A strategy of prophylactic citalopram compared to treatment of emergent depression was not associated with higher adherence or a reduction in treatment-limiting depression nor did it significantly reduce depressive symptoms among HIV-HCV coinfected persons during treatment for HCV.

    ABSTRACT: Objective : This study aimed to study the symptom profile and the role of baseline depressive symptoms in the development of depressive episode in patients receiving a combination of pegylated IFN-alpha and ribavirin. Methods : 82 consecutive patients with HCV infection in whom combination of pegylated interferon-α 2a/2b and ribavirin was prescribed were assessed at baseline and thereafter at 2, 4, 8 and 12 weeks. At the baseline, patients were assessed on Patient Health Questionnaire (PHQ-9), Mini International Neuropsychiatric Interview (MINI) and Beck Depression Inventory (BDI-II). Thereafter patients were assessed on PHQ-9 and when ever found to have Major Depressive Disorder as per PHQ-9, they were assessed on MINI. Those found to have Major Depressive Episode (MDE) on MINI were rated on BDI-II for phenomenology and severity of depression. Results : Common symptoms of pegylated IFN-alpha and ribavirin induced MDE include sadness, irritability, work inhibition, sleep disturbance, fatigability and loss of appetite. Presence of certain depressive symptoms i.e., presence of little interest or pleasure in doing things, feeling tired or having little energy, poor appetite, social withdrawal and work inhibition at the baseline were associated with development of depression during the course of pegylated IFN-alpha plus Ribavirin therapy. Conclusion :Depressive symptoms in patients with pegylated IFN-alpha and ribavirin induced MDE are influenced by the symptoms of depression prior to starting of pegylated IFN-alpha and ribavirin combination. A short screening questionnaire may be constructed which will include the symptoms which predict of development of depression to screen patients at high risk for development of depression.

    ABSTRACT: Interferon-α (IFN-α) is a pleiotropic cytokine that is administered as a therapeutic in highly prevalent medical conditions such as chronic hepatitis C and B virus infection, melanoma and lymphoma. IFN-α induces, to a clinically relevant degree, concentration, memory, drive and mood disturbances in almost half of all patients. For this reason, IFN-α is increasingly being replaced by more specifically acting drugs. In the past decades, IFN-α has offered a valuable insight into the pathogenesis of major depression, particularly in settings associated with inflammation. IFN-α triggers immune responses, hypothalamo-pituitary-adrenal axis abnormalities and disturbances of brain metabolism resembling those in other depression states. IFN-α stimulates indoleamine-2,3 dioxygenase-1, activating the kynurenine pathway with reduced formation of the neurotransmitters serotonin and dopamine, excessive formation of the NMDA agonist quinolinic acid, and reduced formation of the NMDA antagonist kynurenic acid. In addition, IFN-α disturbs neurotrophic signaling and impedes neurite outgrowth, synaptic plasticity, endogenous neurogenesis and neuronal survival. Consequently, IFN-α-related depression may represent a model for the neurodegenerative changes that are noticed in late-life major depression. Indeed, the observation that brain responses in IFN-α-related depression resemble idiopathic depression is supported by the existence of common genetic signatures, among which of note, a number of neuronal survival and plasticity genes have been identified. In view of the high incidence of depressive symptoms, IFN-α-related depression is an attractive model for studying links between neuronal plasticity, neurodegeneration and depression. We predict that in the latter areas new targets for anti-depressant therapies could be identified, which may deepen our understanding of idiopathic major depression.
