Unrelenting depression: ‘I would rather be dead than feel this way’

The authors’ observations

MDD is a mood disorder characterized by depressed mood and/or loss of interest or pleasure for more than 2 weeks.³ First-line pharmacotherapy for MDD includes monotherapy with a selective serotonin reuptake inhibitor (SSRI), serotonin-norepinephrine reuptake inhibitor (SNRI), mirtazapine, or bupropion.⁴ Medication selection is typically based on patient-specific factors, adverse effect profile, drug–drug interactions, and cost. Other treatments include electroconvulsive therapy (ECT) or cognitive-behavioral therapy (CBT).^4,5 Augmentation agents, such as second-generation antipsychotics, lithium, thyroid hormone supplementation, buspirone, anticonvulsants, and combinations of antidepressants, may also be considered.⁴

TREATMENT Condition worsens

On Day 2 of hospitalization, Mr. J is started on aripiprazole, 5 mg/d, clonazepam, 1 mg twice daily, and melatonin, 5 mg, each night for sleep. Aripiprazole, 5 mg/d, is initiated as an adjunct to sertraline for MDD because Mr. J reports feeling much worse and continues to report that he would “rather die than feel this way.” Mr. J begins to believe that his current state is his new baseline, and that feeling better is no longer possible.

On Day 3 of hospitalization, records are obtained from a clinician at an outside facility who previously treated Mr. J; this clinician suspected Mr. J may have bipolar disorder. On Days 3 and 5 of hospitalization, aripiprazole is titrated to 10 mg/d, and then to 20 mg/d, respectively. On Day 6, sertraline is increased to 150 mg/d because Mr. J continues to report low mood and limited sleep and is less and less interactive during interviews. He remains suicidal, and because bipolar depression is suspected (although this is not a clear diagnosis in his records), a trial of divalproex sodium, 250 mg twice daily, is initiated on Day 6.

By Day 8 of hospitalization, there is no notable change in Mr. J’s depressive symptoms. On Day 9, sertraline is increased to 200 mg/d, with little improvement from Mr. J’s perspective. The multidisciplinary team evaluates him, and when directly asked, Mr. J cites his 4 greatest complaints to be poor sleep, fatigue, no appetite, and depressed mood. Once again, he states, “I would rather be dead than go on feeling this way.”

The authors’ observations

Due to Mr. J’s severe, unrelenting depressive episode, the treatment team obtained his informed consent to undergo ECT. On Day 9, before initiating ECT, the pharmacist recommended mirtazapine, even though the patient weighed almost 89 kg (196.21 lb) and had a body mass index of 27.8 kg/m². The treatment team thought that mirtazapine augmentation could potentially help the sertraline work more quickly while targeting Mr. J’s 4 greatest complaints.

Mirtazapine is a central alpha-2 antagonist or noradrenergic and specific serotonergic antidepressant (NaSSA) that works through antagonism of the presynaptic alpha-2 adrenergic receptors to indirectly regulate release of monoamines and increase the release of serotonin and norepinephrine.⁶ Additionally, mirtazapine has antagonist actions at 5HT2A, 5HT2C, 5HT3, and histamine-1 receptors.⁶ Potential adverse effects include drowsiness and increased appetite leading to weight gain.⁷ Mirtazapine’s therapeutic efficacy is similar to SSRIs for treating depression.⁴ Mirtazapine in combination with an SNRI has been referred to as “California rocket fuel” due to the theoretical pharmacologic synergy and resulting strong antidepressant action.⁶ It was hypothesized that similar effects could be seen by augmenting the SSRI sertraline with mirtazapine.
