- BACKGROUND: Electroconvulsive therapy (ECT) is effective for unipolar depression but relapse and suicide are significant challenges. Lithium could potentially lower these risks, but is used only in a minority of patients.AimsThis study quantifies the effect of lithium on risk of suicide and readmission and identifies factors that are associate with readmission and suicide.METHOD: This population-based register study used data from the Swedish National Quality Register for ECT and other Swedish national registers. Patients who have received ECT for unipolar depression as in-patients between 2011 and 2016 were followed until death, readmission to hospital or the termination of the study at the end of 2016. Cox regression was used to estimate hazard ratios (HR) of readmission and suicide in adjusted models.RESULTS: Out of 7350 patients, 56 died by suicide and 4203 were readmitted. Lithium was prescribed to 638 (9%) patients. Mean follow-up was 1.4 years. Lithium was significantly associated with lower risk of suicide (P = 0.014) and readmission (HR 0.84 95% CI 0.75-0.93). The number needed to be treated with lithium to prevent one readmission was 16. In addition, the following factors were statistically associated with suicide: male gender, being a widow, substance use disorder and a history of suicide attempts. Readmission was associated with young age, being divorced or unemployed, comorbid anxiety disorder, nonpsychotic depression, more severe symptoms before ECT, no improvement with ECT, not receiving continuation ECT or antidepressants, usage of antipsychotics, anxiolytics or benzodiazepines, severity of medication resistance and number of previous admissions.CONCLUSIONS: More patients could benefit from lithium treatment.

Tidskriftsartikel (refereegranskat)abstract
- Background: It is unclear whether benzodiazepines increase the risk of suicide. The aim of this study was to test the hypothesis that benzodiazepines are associated with an increased risk of suicide, by comparing psychopharmacological interventions between psychiatric patients who committed suicide and a group of matched controls.Methods: The case group comprised 154 psychiatric patients (101 men, 53 women; age range: 13-96 years) who had committed suicide in orebro County, Sweden. Control psychiatric patients matched by age, sex, and main psychiatric diagnosis were selected for each case. Binary logistic regression was used to calculate odds ratios in unadjusted and adjusted models.Results: Benzodiazepine prescriptions were more common among cases than controls (65/154 [42.2%] versus 43/154 [27.9%], p = 0.009, odds ratio: 1.89 [95% CI: 1.17-3.03]). This association remained significant in a model adjusted for previous suicide attempts and somatic hospitalizations (odds ratio: 1.83 [95% CI: 1.06-3.14]). No statistically significant differences were seen between the groups in the use of any other subtype of psychopharmaceutical agent.Conclusions: These data indicate that benzodiazepine use may increase the risk of suicide. However, this study is limited by the potential for indication bias.

"Treatment Resistance" in Electroconvulsive Therapy (ECT) Patients : Time to Move On
- 2019
-
Ingår i: Acta Psychiatrica Scandinavica. - : Wiley-Blackwell Publishing Inc.. - 0001-690X .- 1600-0447. ; 140:5, s. 490-491

- The concept of "treatment resistance" has become all the rage in depression research. It is used to define populations in research studies and in treatment algorithms as a rationale for moving on from standard antidepressants to other therapies. In such algorithms, electroconvulsive therapy (ECT) is often bundled improperly with less effective neurostimulation-methods and experimental pharmacotherapies.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Electroconvulsive therapy (ECT) is an effective treatment for depression, but there is risk of cognitive adverse events. This risk has been partially attributed to electrical charge, thus the optimal electrical stimulus dose is still under discussion. The aim of this study was to evaluate how the risk of subjective memory worsening was changed after lowering stimulus dose during ECT for patients with major depression.METHOD: A retrospective register-based intervention study of the effects of reduced electrical charges for patients receiving ECT for depression was conducted. The primary outcome was subjective memory worsening and the secondary outcome change in effect on depressive symptoms.RESULTS: A total of 154 patients were enrolled in the study (High dosage group: n = 57; Lower dosage group: n = 97). Subjective memory worsening after ECT occurred in 44% of patients in the high dosage group and in 25% of patients in the lower dosage group(p = 0.014). There was no significant between-group difference in the anti-depressive effect of ECT.LIMITATIONS: The study was register-based and the two groups were not randomized. A large portion of patients were initially excluded due to missing data in the register. The study lacks a long-term follow up.CONCLUSION: After implementing a change of treatment protocol, that lowered ECT stimulus doses from high to moderate, the occurrence of subjective memory worsening was significantly reduced without compromising treatment results.

- Objective Electroconvulsive therapy (ECT) is used in patients with severe forms of bipolar depression. ECT is effective but not all patients respond. The aim of this study was to determine prognostic factors for response to ECT in patients hospitalized for bipolar depression. Methods Data were obtained from several national Swedish registers. All patients with bipolar depression treated with ECT in any hospital in Sweden between 2011 and 2016 for whom information about ECT response was available were included (n = 1251). Response was defined as a score on the Clinical Global Impression - Improvement scale of one or two. Univariate and multivariate logistic regression were conducted to investigate associations between socio-demographic and clinical factors and response. Results Response was achieved in 80.2% patients. Older age was associated with higher response rate to ECT. Patients with comorbid obsessive-compulsive disorder or personality disorder, and patients previously treated with lamotrigine had lower response rate. Conclusion Electroconvulsive therapy for bipolar depression was associated with very high response rates. The strongest prognostic factors were higher age, absence of comorbid obsessive-compulsive disorder or personality disorder, and less prior pharmacologic treatment.

- OBJECTIVES: Electroconvulsive therapy (ECT) is used in some cases of postpartum depression (PPD) and postpartum psychosis (PPP). The risk of relapse for PPD and PPP after ECT is unknown. This study compared the relapse rate after ECT between women who had been treated for PPD and/or PPP and women who had been treated for depression and/or psychosis outside the postpartum period.METHODS: The Swedish National Quality Register for ECT and the Swedish National Patient Register were used to identify women with PPD and/or PPP who had been treated with ECT within 6 months after delivery. For each case, a control (treated with ECT but not postpartum) patient was also selected. A Kaplan-Meier estimator was used to calculate the relapse rate (defined as rehospitalization or suicide) after ECT. Cox regression was used to identify variables associated with relapse.RESULTS: A total of 180 patients were included in each group. The proportions of patients who suffered relapse after 6 months, 1 year, and 2 years were 28%, 31%, and 40% for the postpartum group and 39%, 50%, and 55% for the nonpostpartum group. Treatment with benzodiazepines, several previous psychiatric admissions, and the absence of improvement after ECT were associated with relapse.CONCLUSIONS: The risk of relapse after ECT is lower for patients with PPD and/or PPP than for patients outside the postpartum period, but the risk is nonetheless substantial in both groups.

- PURPOSE: To compare the rate of remission, rate of response, change in depressive symptoms, and adverse effects between repetitive transcranial magnetic stimulation (rTMS) and electroconvulsive therapy (ECT).MATERIALS AND METHODS: In this retrospective case-control study, 35 patients treated for depression with rTMS (left dorsolateral prefrontal cortex, 90% observed motor threshold, 10 Hz, 2000 pulses/session, 15 sessions) at Örebro University Hospital, Sweden (cases), were compared with a matched group of 35 patients treated for depression with ECT (controls). Data on controls were obtained from the Swedish National Quality Register for ECT (Q-ECT). Severity of depression was evaluated using the Montgomery-Åsberg Depression rating scale (MADRS).RESULTS: Remission rate was 26% for cases and 43% for controls (p = .3). Response rate was 40% for cases and 51% for controls (p = .63). The median decrease in MADRS was 11 (IQR 3-19) vs. 17 (IQR 6-27; p = .10) for rTMS and ECT, respectively. There was no statistically significant difference in any measure of treatment effect between rTMS and ECT. More than half of the patients of the rTMS group experienced scalp discomfort and 11% of the ECT group had memory disturbances.CONCLUSIONS: All measures of therapeutic efficacy were numerically inferior in the rTMS group compared to the ECT group. The differences were not statistically significant, probably because the sample size was small. More studies are required to find the optimal place for rTMS within the Swedish health care system. Such studies could be facilitated by inclusion of rTMS in the Q-ECT.
