Question
Should interferon-induced depression respond to antidepressant monotherapy?
Yes
No
Attending physician’s mental notes: initial evaluation
This patient has her first MDE now
This seems superimposed upon GAD, which was likely pre-existing
She is remarkably agitated and looks horribly withdrawn and fatigued
It is acute and precipitated by a medication (Interferon) known to induce MDD in patients being treated for hepatitis
There is some evidence that SSRI and TCA treat interferon-induced depression
– Sometimes SSRIs are used prophylactically as a pretreatment
– She could respond to initial monotherapies
Her initial failure to a subtherapeutic SSRI and SNRI is possibly alarming, but her issue has been intolerance, not inefficacy
She was recently started on a minimally therapeutic dose of a third antidepressant in a novel class
– Mirtazapine (Remeron) is an NaSSA antidepressant
– It is unlikely to be problematic
She has known CYP450 2D6 and 2C19 genetic enzyme deficiencies
Mirtazapine pharmacokinetics include
Approximately 100% of the orally administered dose is excreted via urine and feces within four days
Biotransformation is mainly mediated by the CYP2D6 and CYP3A4 isoenzymes
Inhibitors of these isoenzymes (or those with genetic enzyme deficiencies) cause modest increases in mirtazapine plasma concentrations (17% and 32%, respectively) usually without leading to clinically relevant consequences as mirtazapine has multiple routes of metabolism and clearance
Mirtazapine has little inhibitory effects on CYP isoenzymes and, therefore, the pharmacokinetics of co-administered drugs are usually unaffected
However, her documented CYP450 2D6 liver enzyme deficiency will predispose her to side effects of many drugs and many psychotropics will need to be dose-modified during her care
– Her first two reactions (to an SSRI and SNRI) and side effects clearly worsened her agitation and her trust of psychotropics
Escitalopram (Lexapro) requires CYP450 2C19 and 3A4 enzymes
Her 3A4 system should have been able to metabolize the escitalopram
However, 2C19-deficient patients can show a 1.8-fold increase in escitalopram, making her initial SSRI side effects possibly related to her 2C19 enzyme deficiency
Desvenlafaxine (Pristiq) requires no CYP450 metabolism and is renally excreted; it should not have caused side effects based upon her CYP450 genetic deficiencies
Her side effects appear to be either usual activating side effects or hypochondriacal responses
– She seems convinced and determined that she will be hurt by all interventions
Her clear isoenzyme deficiencies, anxiety, and hypochondriacal thought processes make her prognosis difficult to determine
