[The risk of developing cardiovascular disease in bipolar disorder. Biological factors and therapy].

BACKGROUND: Bipolar disorder (BD) is one of the most common mental disorders characterized by alternating episodes of mania/hypomania and depression, as well as the possibility of developing mixed conditions. Correct and timely diagnosis of BD is important due to the presence of a high suicidal risk and a high predisposition to the development of cardiovascular disease (CVD). The risk of CVD is higher in ВD than in other mental disorders. MATERIALS AND METHODS: A sample assessment was made of current studies focusing on the vascular-bipolar link. The search was carried out in the PubMed and eLIBRARY databases for the following keywords: bipolar disorder, psychopharmacology, cardiovascular disease, biological mediators. RESULTS: There are several biological factors which explain the close association and common pathogenetic mechanisms of BD and CVD. The most interesting of them are inflammation, oxidative stress, and brain-derived neurotrophic factor. Neuroimaging methods have shown similar structural brain changes in people with BD and with CVD. There is some evidence of the efficacy of statins and angiotensin-converting enzyme inhibitors in reducing cardio-vascular risk factors in BD patients. CONCLUSION: The predisposition of patients of BD to CVD is beyond doubt. It is necessary to consider the peculiarities of the course of BD and conduct active monitoring and preventive measures to reduce the risk of developing life-threatening CVDs. Further research focused on the pathogenetic relationship between BD and CVD could provide more insight into this area.

[The risk of developing cardiovascular disease in bipolar disorder. Clinical and social factors].

Bipolar disorder (BD) is one of the most common mental disorders in the world with high mortality and a hard economic burden. Although suicide is the leading cause of death in BD, cardiovascular disease (CVD) also contributes significantly to this rate, the risk of which is seriously underestimated in BD. A sample assessment was made of current studies focusing on the link between BD and CVD. The search was carried out in the PubMed and eLIBRARY databases for the following keywords: bipolar disorder, psychopharmacology, cardiovascular disease, metabolic syndrome. The association between BD and vascular disease is large. The analysis of adjusted mortality estimates in patients with bipolar disorder showed a significant contribution of CVD. A detailed study of the mutual influence of bipolar disorder BD and CVD is difficult due to the earlier manifestation of BD in comparison with CVD. Most of the studies have focused on cardiovascular risk factors (CVRFs), which are more common in BD than in the general population. Metabolic syndrome (MS) plays a significant role among CVRFs. The reasons for the development of MS in patients with BD are currently not known for sure, however, the instigated factors are certainly a disturbance of the diet, decreased physical activity, pharmacological therapy, and the lack of early preventive and medical care. Patients with hyperuricemia had a higher risk of developing MS. Lifestyle correction and a reduction of CVFRs, as well as the rational use of certain cardiac drugs can improve the better prognosis of the disease and reduce mortality in patients with BD. The predisposition of patients with BD to CVD is undeniable. It is necessary to consider the high frequency of CVRFs in people with BD, and promptly recommend appropriate treatment and special rehabilitation programs for the prevention of CVD complications, considering the change in affective phases and the applied mood-stabilizing drugs.

[POEMS-syndrome: diagnostic difficulties].

POEMS syndrome is a rare paraneoplastic syndrome whose name is an acronym formed from the initial letters of the names of the symptoms originally used to determine it: polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes. Due to the rarity of the disease and the small number of cases described in the literature, its diagnosis is difficult. The average time from onset of symptoms to diagnosis is 18 months. Moreover, the prognosis of the disease depends on the early onset of specific treatment. The article describes a clinical case of POEMS-syndrome in a 53-year-old man, which illustrates the difficulties associated with the timely recognition of this unusual disease.
