[SSRI - treatment and bleeding. What risks do we take?]

[Treatment of depression in coronary heart disease]

Depression and coronary heart disease (CHD) are leading causes of disability and show a high comorbidity. Furthermore, depression is an independent risk factor for an unfavorable course and increased mortality in patients with CHD. In contrast, successful treatment of depression can reduce the risk of cardiac events. Currently, there are several treatment options for the management of depression in CHD, including self-management strategies, psychotherapy, pharmacotherapy and collaborative care models. This article provides an overview of the epidemiology of depression in CHD, the mechanisms of association and the current state of evidence with respect to the different treatment options.

Depressive syndromes in neurological disorders

Depressive syndromes represent a common and often characteristic feature in a number of neurological disorders. One prominent example is the development of post-stroke depression, which can be observed in more than one-third of stroke survivors in the aftermath of an ischemic stroke. Thus, post-stroke depression represents one of the most prevalent, disabling, and potentially devastating psychiatric post-stroke complications. On the other hand, depressive syndromes may also be considered as a risk factor for certain neurological disorders, as recently revealed by a meta-analysis of prospective cohort studies, which demonstrated an increased risk for ischemic events in depressed patients. Moreover, depressive syndromes represent common comorbidities in a number of other neurological disorders such as Parkinson's disease, multiple sclerosis, or epilepsy, in which depression has a strong impact on both quality of life and outcome of the primary neurological disorder.

[Depression and neurological diseases]

In many neurological diseases a depressive syndrome is a characteristic sign of the primary disease or is an important comorbidity. Post-stroke depression, for example, is a common and relevant complication following ischemic brain infarction. Approximately 4 out of every 10 stroke patients develop depressive disorders in the course of the disease which have a disadvantageous effect on the course and the prognosis. On the other hand depression is also a risk factor for certain neurological diseases as was recently demonstrated in a meta-analysis of prospective cohort studies which revealed a much higher stroke risk for depressive patients. Furthermore, depression plays an important role in other neurological diseases with respect to the course and quality of life, such as Parkinson's disease, multiple sclerosis and epilepsy. This article gives a review of the most important epidemiological, pathophysiological and therapeutic aspects of depressive disorders as a comorbidity of neurological diseases and as a risk factor for neurological diseases.

SSRI-induced coagulopathy: is it reality?

OBJECTIVES

To study the effect of escitalopram and fluoxetine on coagulation profile in patients with major depression.

METHOD

This was a prospective, open-label, single-centre study in 40 patients diagnosed with major depressive disorder. The patients were diagnosed using Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. Twenty patients receiving escitalopram 10 mg per day and 20 patients receiving fluoxetine 20 mg per day participated in the study and were followed up for 3 months. Coagulation parameters - bleeding time, clotting time, platelet count, prothrombin time and partial thromboplastin kaolin time - were evaluated at baseline and after 3 months.

RESULTS

At the end of 3 months, a significant increase in bleeding time was seen in patients receiving fluoxetine, but within the normal range. No rise was seen in the group given escitalopram.

CONCLUSION

In patients with depression, fluoxetine increases bleeding time whereas escitalopram has no effect on coagulation profile. However, both the drugs can be used safely for long-term treatment.
