The impact of selective serotonin reuptake inhibitors on the risk of intracranial haemorrhage: A systematic review and meta-analysis

Clinical considerations in early-onset cerebral amyloid angiopathy

Cerebral amyloid angiopathy (CAA) is an important cerebral small vessel disease associated with brain haemorrhage and cognitive change. The commonest form, sporadic amyloid-β CAA, usually affects people in mid- to later life. However, early-onset forms, though uncommon, are increasingly recognized and may result from genetic or iatrogenic causes that warrant specific and focused investigation and management. In this review, we firstly describe the causes of early-onset CAA, including monogenic causes of amyloid-β CAA (APP missense mutations and copy number variants; mutations of PSEN1 and PSEN2) and non-amyloid-β CAA (associated with ITM2B, CST3, GSN, PRNP and TTR mutations), and other unusual sporadic and acquired causes including the newly-recognized iatrogenic subtype. We then provide a structured approach for investigating early-onset CAA, and highlight important management considerations. Improving awareness of these unusual forms of CAA amongst healthcare professionals is essential for facilitating their prompt diagnosis, and an understanding of their underlying pathophysiology may have implications for more common, late-onset, forms of the disease.

Examining the Association Between Serotonergic Antidepressants and Blood Transfusion Requirements in Orthopaedic Surgery: A Comprehensive Analysis

AIM

The study aimed to investigate the association between the use of serotonergic antidepressants and blood transfusion requirements in orthopedic surgical patients.

METHODOLOGY

A retrospective follow-up study was conducted at Kota Trauma Hospital, Kota, Rajasthan focusing on patients who underwent orthopedic surgeries between November 2021 through December 2022. Patients were categorized into two groups: users of serotonergic antidepressants and users of other antidepressants (non-selective serotonergic antidepressants). The requirement for blood transfusion for both groups was assessed. Covariate factors, such as medication use and comorbidities (e.g., diabetes mellitus, cardiovascular diseases), were examined to control potential confounding variables.

RESULT

A total of 170 subjects with complete medical records were included in the study. The results presented a significant association between the usage of serotonergic antidepressants and blood transfusion requirements (p=0.001). While no significant differences between the two groups were observed in perioperative hemoglobin levels and fluid infusion, there was a significant difference in blood loss and postoperative drainage.

CONCLUSION

Serotonergic antidepressant usage was correlated with increased blood transfusion requirements in orthopedic surgery patients on antidepressants. The study underscores the importance of considering medication factors in perioperative management and highlights potential implications for patient care strategies.

Incidence of bleeding events in patients on concomitant tyrosine kinase inhibitors and selective serotonin reuptake inhibitors

INTRODUCTION

In this study, we aim to determine the risk of bleeding or thrombosis with concurrent use of tyrosine kinase inhibitors (TKIs) used to treat CML, and serotonin reuptake inhibitors (SSRIs).

METHODS

We conducted a retrospective cohort study of patients with CP-CML cared for at Massachusetts General Hospital (MGH) between April 2016 to February 2021. Participants were included if diagnosed with CP-CML and began TKI treatment (imatinib, dasatinib, nilotinib, bosutinib, or ponatinib) after April 2016.

RESULTS

One hundred patients were evaluated, eighty of whom were taking TKIs only (median age 55, 40% female), and twenty were taking TKI and SSRI concomitantly (median age 53.5, 55% female). Baseline demographics between these groups were similar across all variables. Patients in the TKI only group had 9 bleeding events and 3 thrombotic events. Patients in the combination group had 6 bleeding events and 1 thrombotic event. There was no difference between overall rates of major bleeding (4% v. 10%, p = 0.26) or thrombotic events (4% v. 5%, p = 1). However, patients in the combination group were more likely to have major intracranial bleeding events (0% v. 10%, p = 0.04), and there was a trend to significance for minor bleeding events (7.5% v. 20%, p = 0.11).

CONCLUSIONS

Concomitant use of TKIs and SSRIs does not appear to increase the total risk of bleeding or thrombotic events compared to patients on TKIs only. However, concomitant use of TKIs and SSRIs may increase risk of intracranial bleeding. Further work is needed to fully assess this risk.

Depression and Suicide Risk Screening: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

Importance

Depression is common and associated with substantial burden. Suicide rates have increased over the past decade, and both suicide attempts and deaths have devastating effects on individuals and families.

Objective

To review the benefits and harms of screening and treatment for depression and suicide risk and the accuracy of instruments to detect these conditions among primary care patients.

Data Sources

MEDLINE, PsychINFO, Cochrane library through September 7, 2022; references of existing reviews; ongoing surveillance for relevant literature through November 25, 2022.

Study Selection

English-language studies of screening or treatment compared with control conditions, or test accuracy of screening instruments (for depression, instruments were selected a priori; for suicide risk, all were included). Existing systematic reviews were used for treatment and test accuracy for depression.

Data Extraction and Synthesis

One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Findings were synthesized qualitatively, including reporting of meta-analysis results from existing systematic reviews; meta-analyses were conducted on original research when evidence was sufficient.

Main Outcomes and Measures

Depression outcomes; suicidal ideation, attempts, and deaths; sensitivity and specificity of screening tools.

Results

For depression, 105 studies were included: 32 original studies (N=385 607) and 73 systematic reviews (including ≈2138 studies [N ≈ 9.8 million]). Depression screening interventions, many of which included additional components beyond screening, were associated with a lower prevalence of depression or clinically important depressive symptomatology after 6 to 12 months (pooled odds ratio, 0.60 [95% CI, 0.50-0.73]; reported in 8 randomized clinical trials [n=10 244]; I2 = 0%). Several instruments demonstrated adequate test accuracy (eg, for the 9-item Patient Health Questionnaire at a cutoff of 10 or greater, the pooled sensitivity was 0.85 [95% CI, 0.79-0.89] and specificity was 0.85 [95% CI, 0.82-0.88]; reported in 47 studies [n = 11 234]). A large body of evidence supported benefits of psychological and pharmacologic treatment of depression. A pooled estimate from trials used for US Food and Drug Administration approval suggested a very small increase in the absolute risk of a suicide attempt with second-generation antidepressants (odds ratio, 1.53 [95% CI, 1.09-2.15]; n = 40 857; 0.7% of antidepressant users had a suicide attempt vs 0.3% of placebo users; median follow-up, 8 weeks). Twenty-seven studies (n = 24 826) addressed suicide risk. One randomized clinical trial (n=443) of a suicide risk screening intervention found no difference in suicidal ideation after 2 weeks between primary care patients who were and were not screened for suicide risk. Three studies of suicide risk test accuracy were included; none included replication of any instrument. The included suicide prevention studies generally did not demonstrate an improvement over usual care, which typically included specialty mental health treatment.

Conclusions and Relevance

Evidence supported depression screening in primary care settings, including during pregnancy and postpartum. There are numerous important gaps in the evidence for suicide risk screening in primary care settings.

Association between selective serotonin and serotonin-noradrenaline reuptake inhibitor therapy and hematuria

BACKGROUND

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) are used as first-line treatment for many psychiatric diseases, especially major depressive disorder. However, an important side effect of these drugs is the risk of bleeding due to platelet dysfunction. The aim of this study was to determine the frequency of hematuria in patients using SSRI/SNRIs and to compare with a control group.

METHODS

This study included patients who were followed up and treated with SSRI/SNRI in the psychiatric outpatient clinic of the Antalya Medical Park Hospital between 1 January 2021 and 31 March 2021 and a control group comprising patients who presented to the medical check-up outpatient clinic between the same dates. Complete urinalysis was performed for all patients and the results were compared between the groups.

RESULTS

Each group included 100 patients with a female/male ratio of 1. The mean age was 41.45 ± 13.47 (16-74) years in the study group and 40.51 ± 13.75 (20-70) years in the control group (p = 0.519). Mean duration of SSRI/SNRI use in the study group was 13.35 ± 1.32 (1-64) months. The prevalence of hematuria was 17% in the SSRI/SNRI group and 6% in the control group (p = 0.015). All cases of hematuria were microscopic hematuria.

CONCLUSION

Hematuria is significantly more common in patients receiving SSRI/SNRI treatment. The use of SSRI/SNRI should also be taken into account when investigating the etiology of hematuria.

Use of serotonin reuptake inhibitor antidepressants and the risk of bleeding complications in patients on anticoagulant or antiplatelet agents: a systematic review and meta-analysis

BACKGROUND

Serotonin reuptake inhibitor (SRI) antidepressants are implicated in increasing the risk of bleeding among users; however, the comparative increase in bleeding risk with concurrent antithrombotic therapy (anticoagulant or antiplatelet) remains unclear. As such, we performed a systematic review and meta-analysis of all available evidence to evaluate the effects of SRI and the risk of bleeding complications among patients receiving antithrombotic therapy.

METHODS

We searched Medline, Embase, PubMed, PsycINFO, Cochrane Library, Web of Science, Scopus, CINAHL, and grey literature (Google Scholar and preprint reports) up to 26 November, 2020, with no language restrictions (updated on 31 July 2021). The primary outcome of interest was major bleeding. Secondary outcomes included intracranial haemorrhage, gastrointestinal bleeding, and any bleeding events. We used a random-effects model meta-analysis to estimate the odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

We did not identify any randomised studies but found 32 non-randomized studies (cohort or case-control) with 1,848,285 patients that fulfilled the study selection criteria and were included in the meta-analysis. Among individuals receiving anticoagulants (13 studies), SRI users experienced a statistically higher risk of major bleeding compared to non-SRI users: pooled OR was 1.39 (95% CI, 1.23-1.58; p < .001; moderate heterogeneity). Among individuals receiving antiplatelet therapy (2 studies), SRI users were associated with an increased risk of major bleeding: pooled OR was 1.45 (95% CI, 1.17-1.80; p = .001; low heterogeneity). For secondary outcomes, the use of SRI among individuals treated with antithrombotic therapy revealed a higher risk of gastrointestinal bleeding or any bleeding events, whereas only anticoagulant use was illustrated an increased risk of intracranial haemorrhage.

CONCLUSIONS

The use of SRI antidepressants among patients treated with antithrombotic therapy (either anticoagulant or antiplatelet) is associated with a higher risk of bleeding complications, suggesting that caution is warranted in co-prescription.

PROSPERO REGISTRATION

CRD42018083917KEY MESSAGESIn this meta-analysis of 32 non-randomized studies, SRI users were associated with the risk of bleeding complications compared to non-SRI users, with concurrent antithrombotic use (either anticoagulant or antiplatelet).The risk was consistently elevated across types of bleeding events (major bleeding, gastrointestinal bleeding, or any bleeding events), whereas only anticoagulant use was associated with intracranial haemorrhage.To promote the rational use of medicines, our findings suggest that the risk-benefit ratio must account for the clear efficacy of SRI against safety concerns in terms of bleeding risks.

Safety considerations for prescribing SSRI antidepressants to patients at increased cardiovascular risk

INTRODUCTION

With the development of selective serotonin reuptake inhibitors (SSRI), a relatively uncomplicated treatment of depression and a safer alternative to tricyclic antidepressants was introduced. Any medical treatment has potential safety risks, however, and these risks should also be considered when prescribing SSRIs.

AREAS COVERED

The present review focuses on safety considerations when prescribing SSRIs to patients with previous stroke and myocardial infarction, as depression, and the need for antidepressant treatment, is common in these patients. At the same time, patients with stroke and myocardial infarction may be at increased risk of developing adverse events due to higher age, comorbidity, and co-medication. Specifically, the evidence of the risk of QT prolongation and bleeding versus thrombotic events will be discussed in the present review.

EXPERT OPINION

No medical treatment comes without risk and SSRIs are no exception. Depression, a common complication after vascular events, is a potentially life-threatening condition in itself and relevant and sufficient treatment is imperative. SSRIs are often the first medical treatment choice in the ambulatory setting, also in patients at increased cardiovascular risk. Relevant comorbidity and co-medication, however, should always be taken into account when initiating treatment and when choosing a specific SSRI.

Association of Selective Serotonin Reuptake Inhibitor Use After Intracerebral Hemorrhage With Hemorrhage Recurrence and Depression Severity

IMPORTANCE

Selective serotonin reuptake inhibitors (SSRIs) are widely used to treat poststroke depression but are associated with increased incidence of first-ever intracerebral hemorrhage (ICH) in the general population. The decision to treat ICH survivors with SSRIs must therefore balance potential risks of ICH recurrence with presumed benefits on depressive symptoms.

OBJECTIVE

To determine whether SSRI use among survivors of primary ICH was associated with ICH recurrence and decreased severity of depressive symptoms.

DESIGN, SETTING, AND PARTICIPANTS

Longitudinal ICH cohort study at a tertiary care center enrolling from January 2006 to December 2017, with follow-up for a median of 53.2 months (interquartile range, 42.3-61.2 months). The study included 1279 consenting individuals (1049 White, 89 Black, 77 Hispanic, and 64 other race/ethnicity) of 1335 eligible patients presenting with primary ICH and who were discharged alive from initial hospitalization for stroke.

MAIN OUTCOMES AND MEASURES

We conducted univariable and multivariable analyses for ICH recurrence risk and depression severity, including subset analyses for patients with 1 or more of the following characteristics associated with high ICH recurrence risk: (1) lobar ICH; (2) presence of the apolipoprotein ε2/ε4 gene variants; (3) prior history of ICH/TIA/ischemic stroke; and (4) Black or Hispanic race/ethnicity.

RESULTS

Mean age of study participants was 71.3 years, with 602 women (47%); of the 1279 participants, 1049 were White, 89 were Black, 77 were Hispanic, and 64 were other race/ethnicity. SSRI exposure was associated with both ICH recurrence (subhazard ratio [SHR], 1.31; 95% CI, 1.08-1.59) and resolution of post-ICH depression (SHR, 1.53; 95% CI, 1.12 2.09). Among those individuals at high risk for recurrent ICH, SSRIs were associated with further elevation in risk for ICH recurrence (SHR, 1.79; 95% CI, 1.22-2.64) compared with all other survivors of ICH (SHR, 1.20; 95% CI, 1.01-1.42; P = .008 for comparison of effect sizes). The association of SSRI with reduced depressive symptoms did not differ between high those at high risk for recurrent ICH and all other ICH survivors.

CONCLUSIONS AND RELEVANCE

Selective serotonin reuptake inhibitor exposure after ICH is associated with both improvement in depressive symptoms and increased risk of recurrent hemorrhagic stroke. Clinical history, neuroimaging data, and genetic biomarkers may help to identify survivors of ICH more likely to safely tolerate SSRI use.

Neuropsychiatric issues after stroke: Clinical significance and therapeutic implications

A spectrum of neuropsychiatric disorders is a common complication from stroke. Neuropsychiatric disorders after stroke have negative effects on functional recovery, increasing the rate of mortality and disability of stroke survivors. Given the vital significance of maintaining physical and mental health in stroke patients, neuropsychiatric issues after stroke have raised concerns by clinicians and researchers. This mini-review focuses on the most common non-cognitive functional neuropsychiatric disorders seen after stroke, including depressive disorders, anxiety disorders, post-traumatic stress disorder, psychosis, and psychotic disorders. For each condition, the clinical performance, epidemiology, identification of the therapeutic implication, and strategies are reviewed and discussed; the main opinions and perspectives presented here are based on the latest controlled studies, meta-analysis, or updated systematic reviews. In the absence of data from controlled studies, consensus recommendations were provided accordingly.
