Outcome in refractory depression

Journal of Affective Disorders, 1999

Background: Failure to respond to first-line antidepressant treatment can occur in up to 40% of patients with depressive illness. A proven strategy for managing this refractory depression is lithium augmentation. The long-term outcome and optimal management of patients treated with lithium augmentation remains unclear. We describe a 4-8 year naturalistic follow-up of patients treated with lithium augmentation in two controlled studies of its efficacy in refractory depression. Method: Cases were followed up with personal interview where possible, and by telephone and general practitioner contact otherwise. Lifetime clinical status was ascertained using the Schedule for Affective Disorders and Schizophrenia-Lifetime (SADS-L). Results: We obtained outcome data on 53 of the original eligible 76 patients. There was a good outcome in 38 (72%) patients. Good outcome was associated with a less endogenous nature of depression and an absence of previous hospitalisations. Conclusions: There do not seem to be any specific prognostic indicators of long-term outcome to lithium augmentation beyond those recognised to be relevant in the outcome of depression generally. Limitations: The conclusions are limited by incomplete follow-up of the total original sample and lack of objective illness and medication data for the intervening period.

Acute Antidepressive Efficacy of Lithium Monotherapy, Not Citalopram, Depends on Recurrent Course of Depression

Journal of Clinical Psychopharmacology, 2013

Studies of the 1970s and 1980s showed lithium monotherapy to be an effective treatment of acute unipolar major depressive disorder (MDD) and hence as a potential alternative to monoaminergic antidepressants. The objective was to conduct the first comparison of a lithium monotherapy with a modern antidepressant in the acute treatment of MDD. Results were compared with citalopram's efficacy as shown in a different but methodologically identical study (including same researchers, same time, and same place). Thirty patients with an acute MDD (Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM IV] I) were treated with lithium monotherapy (study 1) or with citalopram monotherapy (study 2, N = 32) for 4 weeks. Response rates (decrease in Hamilton Depression Rating Scale score 950%) were 50% for lithium and 72% for citalopram (P = 0.12). Citalopram-treated subjects showed a greater decrease in Hamilton Depression Rating Scale scores (significant at 2 weeks). In the lithium study, only patients with a recurrent episode (DSM-IV: 296.3) responded (15/22), as opposed to none of 8 patients with a first/single episode (DSM-IV: 296.2) (P = 0.002). Patients with a single episode responded significantly more often to citalopram than to lithium (P = 0.007). Both drugs were well tolerated. Only one patient (citalopram) terminated the study prematurely owing to adverse effects. Our results do not support the use of lithium as an alternative to SSRI in the treatment of acute MDD. The finding of a better response to lithium in patients with a recurrent depression has not been reported before and warrants replication. The comparison is limited by the lack of a randomized double-blind design.

Comparative efficacy of lithium and amitriptyline in the maintenance treatment of recurrent unipolar depression: a randomised study

Journal of Affective Disorders, 1996

The present study, including 81 depressive patients, compares the prophylactic efficacy of lithium and amitriptyline in recurrent unipolar depression over a treatment period of 2.5 years in a randomised multicentre design. Hospitalisation, re-emergence of depressive or subdepressive recurrences, unwanted side-effects and need of concomitant psychotropic medication were considered to indicate treatment failures. Average dosage for amitriptyline was 98 + 37 mg/day, average lithium blood level was 0.59 f 0.12 mmol/l. Survival analyses demonstrated a significant superiority of lithium (P = 0.015) regarding the outcome criteria 'recurrences and/or subclinical recurrences' and non-significantly better results of lithium compared to amitriptyline concerning 'recurrence' (P = 0.059) or 'recurrence and/or concomitant medication' (P = 0.066).

Is the polarity of relapse/recurrence in bipolar-I disorder patients related to serum lithium levels? Results from an empirical study

Journal of Affective Disorders, 2009

Background: Preliminary evidence suggests that the polarity of relapse/recurrence (depressive vs. hypomanic/manic/mixed) in bipolar patients on lithium might be related to serum lithium levels. Methods: Polarity of episodes in 64 bipolar-I patients on lithium monotherapy during a prospective 18-month maintenance trial was predicted from (a) intra-individual oscillations of lithium levels over time and from (b) absolute lithium levels preceding relapse/recurrence. Results: On an individual basis, depressive (vs. hypomanic/manic/mixed) episodes were mostly preceded by lithium levels above the individual means (p b 0.001). Relapse/recurrence occurring at lithium levels above the overall mean serum level of 0.66 mmol/l was depressive (not hypomanic/manic/mixed) in most cases (odds-ratio = 3.86, p = 0.032). Lithium levels before depressive episodes were numerically higher than before hypomanic/manic/mixed episodes (0.769 ± 0.242 vs. 0.675 ± 0.262 mmol/l, p = 0.13). Cox-regression including current lithium levels as time-dependent predictor essentially confirmed these results. Limitations: As patients were not randomized to specific lithium levels, potential confounders could not be completely ruled out. Furthermore, a closer than monthly assessment of both lithium levels and psychopathology would have been desirable to better understand the interplay between lithium levels and new mood episodes.

How Long Should the Lithium Augmentation Strategy be Maintained? A 1-Year Follow-up of a Placebo-Controlled Study in Unipolar Refractory Major Depression

Journal of Clinical Psychopharmacology, 2002

There is compelling evidence from placebocontrolled studies that lithium augmentation is an effective strategy in the acute and continuation treatment of refractory unipolar major depression. Authors prospectively investigated the 1-year outcome of 22 subjects diagnosed with unipolar major depression who had participated in a 4-month placebo-controlled, double-blind continuation study of lithium augmentation without relapse. At the end of the double-blind phase, the blinded medication (lithium in 14 patients, placebo in 8 patients) was tapered off over a 1-week period, while the antidepressant was continued at the same dosage for another 4 weeks. Subsequently, the antidepressant was gradually discontinued over a 4-week period. Clinical status was assessed at regular follow-up visits. During the open 6-month follow-up period, seven subjects suffered an affective recurrence, five of whom had received lithium during the placebo-controlled, double-blind phase of the study. Study data suggest that active medication should be maintained for at least 1 year after successful lithium augmentation in patients with unipolar major depressive disorder.

Sixteen-year mortality in patients with affective disorder commenced on lithium

The British Journal of Psychiatry, 2000

Background Lithium treatment is claimed to reduce mortality in patients with affective disorder, but the evidence is conflicting. Aim To estimate mortality rates from a cohort of patients with affective disorder commenced on lithium with an observation period of two years and a follow-up after 16 years. Method The mortality rates of patients were compared with those of the general Danish population, standardised for age, gender and calendar time with respect to death from all causes, suicide and death from cardiovascular disease. Results Forty of the study's 133 patients died during the 16-year observation period (11 from suicide). Mortality among patients commenced on lithium was twice that of the general population. The statistically significantly elevated mortality was due largely to an excess of suicides; mortality from all other causes was similar to the background populations. Thirty-two patients died after the first two years of observation and were included in the analys...

Lithium prophylaxis of recurrent bipolar affective disorder: Long-term outcome and its psychosocial correlates

Journal of Affective Disorders, 1999

Background: Discrepancy between efficacy of prophylactic lithium and its effectiveness in ordinary clinical practice necessitates long-term follow-up data from specialised lithium clinics. Also, role of psychosocial factors in influencing the outcome is unclear. Methods: One hundred and eighteen patients of bipolar affective disorder attending a lithium clinic were followed-up for ∼11 years (range 2–27 years). Demographic and clinical data, measures of social support and psychosocial stress were obtained at the intake in 1989–1990. Study design combined retrospective chart-review (till the time of intake) with prospective follow-up till July 1995. Results: On lithium, the patients had a mean of 0.43 relapses per year (manic, 0.26; depressive, 0.17) which was significantly less (p<0.01) than the pre-lithium episode frequency. The figure for entirely relapse-free patients was 24%, and 62% had relapses up to one episode per year (median=0.3 per year). Fifty-eight (49%) patients were good responders to lithium (relapses≤0.30 per year). In comparison to good responders, partial/poor responders had a significantly greater number of pre-lithium depressive episodes, poor lithium compliance, more psychosocial stress and lower social support at intake. These variables correlated well with relapses and explained 32% of the variance of the data. Conclusions: Lithium had a definite prophylactic effect on long-term outcome. Social support and stressful life events are significant correlates of response to lithium. Clinical Implications: Lithium prophylaxis of bipolar affective disorders seems justified though psychosocial factors appear to modulate its effectiveness. Limitations: Other psychotropic medications were used during relapse and the assessment of psychosocial factors was cross-sectional.

Outcome of lithium prophylaxis: a prospective follow‐up of affective disorder patients assigned to high and low serum lithium levels

Acta Psychiatrica Scandinavica, 1998

The purpose of the study was to examine the outcome of long‐term lithium treatment in consecutively admitted affective disorder patients assigned to high and low serum lithium levels. A total of 91 patients were diagnosed according to DSM‐III criteria and randomly allocated to two open treatment groups in which prophylactic lithium was administered in high (serum lithium 0.8‐1.0 mmol L‐1) and low (serum lithium 0.5‐0.8 mmol L‐1) doses, respectively. The patients were followed for 2 years or until discontinuation of lithium treatment or readmission to hospital for recurrence of affective illness. The main outcome of the treatment groups was compared with Kaplan‐Meier survival curves and by Cox regression analysis. A total of 31 patients (34%) completed 24 months of prophylactic lithium treatment without recurrence and readmission to hospital. In total, 18 patients (20%) suffered a recurrence on lithium, and 42 patients (46%) discontinued lithium or were lost to follow‐up. No effect o...
