INTRODUCTION: The aim of this work was to summarize relationships between two subtypes of major depressive disorder (melancholic and atypical) and four core features of depression that reflect the domains identified consistently in previous studies of major depressive disorder endophenotypes (exaggerated reactivity to negative information, altered reward processing, cognitive control deficits, and somatic symptoms) on the one hand and selected peripheral inflammatory markers (C-reactive protein [CRP], cytokines, and adipokines) on the other. METHODS: A systematized review was conducted. The database used for searching articles was PubMed (MEDLINE). RESULTS: According to our search, most peripheral immunological markers associated with major depressive disorder are not specific to a single depressive symptom group. The most evident examples are CRP, IL-6, and TNF-α. The strongest evidence supports the connection of peripheral inflammatory markers with somatic symptoms; weaker evidence indicates a role of immune changes in altered reward processing. The least amount of evidence was found for the role of peripheral inflammatory markers in exaggerated reactivity to negative information and cognitive control deficits. Regarding the depression subtypes, a tendency for higher CRP and adipokines was observed in atypical depression; increased IL-6 was found in melancholic depression. CONCLUSION: Somatic symptoms of depression could be a manifestation of a specific immunological endophenotype of depressive disorder. Melancholic and atypical depression may be characterized by different profiles of immunological markers.

OBJECTIVE: To evaluate the need for cardiac monitoring in unselected patients recovered from COVID-19 and to estimate the risk of heart complications after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). MATERIALS AND METHODS: During March 2020 and January 2021, 106 patients who had recovered from SARS-CoV-2 (alpha and beta variants) were enrolled in prospective observational cohort study CoSuBr (Covid Survivals in Brno). The diagnosis was based on a reverse transcription-polymerase chain reaction swab test of the upper respiratory tract. Demographic parameters, patient history, clinical evaluation, cardiac biomarkers, ECG and echocardiography were recorded during three visits (Visit 1 at least 6 weeks after infection, Visit 2 three months later, and Visit 3 one year after Visit 1). RESULTS: 58.5% of the study group (n = 106) were female, while the mean age was 46 years (range 18-77 years). The mean time interval between the onset of infection and the follow-up visit was 107 days. One quarter (24.5%) of the patients required hospitalization during the acute phase of the disease; the rest recovered at home. 74% suffered a mild form of the disease, with 4.8, 18.1, and 2.9% suffering moderate, severe, and critical forms, respectively. At the time of enrolment, 64.2% of the patients reported persistent symptoms, while more than half of the whole group (50.9%) mentioned at least one symptom of possible cardiac origin (breathing problems, palpitations, exercise intolerance, fatigue). In the 1-year follow-up after COVID-19 infection, left ventricle ejection fraction showed no significant decrease [median (IQR) change was -1.0 (-6.0; 4.0)%, p = 0.150], and there were no changes of troponin (mean change -0.1 ± 1.72 ng/L; p = 0.380) or NT-proBNP [median (IQR) change 2.0 (-20.0; 29.0) pg/mL; p = 0.315]. There was a mild decrease in right ventricle end diastolic diameter (-mean change 2.3 ± 5.61 mm, p < 0.001), while no right ventricle dysfunction was detected. There was very mild progress in left ventricle diastolic diameter [median (IQR) change 1.0 (-1.0; 4.0) mm; p = 0.001] between V1 and V3, mild enlargement of the left atrium (mean change 1.2 ± 4.17 mm; p = 0.021) and a non-significant trend to impairment of left ventricle diastolic dysfunction. There was a mild change in pulmonary artery systolic pressure [median (IQR) change 3.0 (-2.0; 8.0) mmHg; p = 0.038]. CONCLUSION: Despite a lot of information regarding cardiac impairment due to SARS-CoV2, our study does not suggest an increased risk for developing clinically significant heart changes during the 1-year follow-up. Based on our results, routine echocardiography and biomarkers collection is currently not recommended after COVID-19 recovery.

Objective: To discuss the impact of depression on work and how depression-related sick leave duration could be a potential indicator and outcome for measuring functionality in depression.Methods: Our review was based on a literature search and expert opinion that emerged during a virtual meeting of European psychiatrists that was convened to discuss this topic.Results: Current evidence demonstrates that depression-related sick leave duration is influenced by multiple disease-, patient- and work-related factors, together with societal attitudes towards depression and socioeconomic conditions. A wide variety of pharmacological and non-pharmacological treatments and work-based interventions are effective in reducing depression-related sick leave duration and/or facilitating return to work. Recent real-world evidence showed that patients treated with antidepressant monotherapy appear to recover their working life faster than those receiving combination therapy. Although depression-related sick leave duration was found to correlate with severity of depressive symptoms, it cannot be used alone as a viable marker for disease severity.Conclusions: Given its multifactorial nature, depression-related sick leave duration is not on its own a viable outcome measure of depression severity but could be used as a secondary outcome alongside more formal severity measures and may also represent a useful measure of functionality in depression. Key pointsDepression in the working population and depression-related sick leave have a profound economic impact on societyDepression-related sick leave duration is influenced by multiple disease-, patient- and work-related factors, together with societal attitudes towards depression and socioeconomic conditionsA wide variety of pharmacological and non-pharmacological treatments and work-based interventions have been shown to be effective in reducing depression-related sick leave duration and/or facilitating return to workIn terms of pharmacological intervention, recent real-world evidence has shown that patients treated with antidepressant monotherapy are able to recover their working life faster than those treated with combination therapyAlthough depression-related sick leave duration has been shown to correlate with severity of depressive symptoms, it is not a viable outcome measure of depression severity on its own, but could be used as secondary outcome alongside more formal clinician- and patient-rated severity measuresDepression-related sick leave duration may, however, represent a viable outcome for measuring functionality in depression.

OBJECTIVES: Osteocalcin is a protein secreted by osteoblasts with a versatile endocrine role. Several domains in which it plays a role-stress response, monoamine synthesis, and cognitive functioning-are implicated also in the pathophysiology of major depressive disorder. In search of possible objective biomarkers of depression, the aim of the study was to assess the relationship between osteocalcin and depressive symptoms during the treatment of depressive episode. METHODS: The study included female inpatients with at least moderate depressive episode. In these patients, depression severity was measured using the Montgomery-Åsberg Depression Rating Scale (MADRS), and osteocalcin levels were assessed before the stabilization of antidepressive treatment and after 6 weeks. Relationships between osteocalcin levels and symptoms were analyzed with mixed-effect and linear models, taking into account age, menopausal status, and body mass index. RESULTS: In 11 out of 13 enrolled inpatients, osteocalcin levels decreased during the first 6 weeks of treatment; this decrease was significant according to the mixed-effects model (t = -2.345, p = 0.019). According to the linear model, this decrease was significantly associated with reduction in depressive symptom severity (t = 2.673, p = 0.028). Osteocalcin was not associated with initial depressive symptom severity, and initial osteocalcin levels did not predict response to treatment. Limitations of the study include low sample size and inclusion of both pre- and postmenopausal women of various ages. CONCLUSIONS: This preliminary study suggests that osteocalcin may be a candidate biomarker of antidepressive treatment response and that this topic warrants further investigation.

OBJECTIVE: Currently available methods for endogenous cortisol monitoring in patients with hormonal insufficiency rely on measurements of plasma levels only at a single time point; thus, any kind of chronic exposure to cortisol is challenging to evaluate because it requires collecting samples at different time points. Hair cortisol levels acquired longitudinally better reflected chronic exposure (both cortisol synthesis and deposition) and may significantly contribute to better outcomes in glucocorticoid replacement therapies. DESIGN: Twenty-two patients on cortisol substitution therapy were monitored for plasma, urinary, and hair cortisol levels for 18 months to determine whether hair cortisol may serve as a monitoring option for therapy setting and adjustment. METHODS: Plasma and urinary cortisol levels were measured using standardized immunoassay methods, and segmented (∼1 cm) hair cortisol levels were monitored by liquid chromatography coupled to mass spectrometry. A log-normal model of the changes over time was proposed, and Bayesian statistics were used to compare plasma, urinary, and hair cortisol levels over 18 months. RESULTS AND CONCLUSIONS: Hair cortisol levels decreased over time in patients undergoing substitutional therapy. The residual variance of hair cortisol in comparison to plasma or urinary cortisol levels was much lower. Thus, longitudinal monitoring of hair cortisol levels could prove beneficial as a noninvasive tool to reduce the risk of overdosing and improve the overall patient health.

The cellular pathology of schizophrenia and the potential of antipsychotics to target underlying neuronal dysfunctions are still largely unknown. We employed glutamatergic neurons derived from induced pluripotent stem cells (iPSC) obtained from schizophrenia patients with known histories of response to clozapine and healthy controls to decipher the mechanisms of action of clozapine, spanning from molecular (transcriptomic profiling) and cellular (electrophysiology) levels to observed clinical effects in living patients. Glutamatergic neurons derived from schizophrenia patients exhibited deficits in intrinsic electrophysiological properties, synaptic function and network activity. Deficits in K+ and Na+ currents, network behavior, and glutamatergic synaptic signaling were restored by clozapine treatment, but only in neurons from clozapine-responsive patients. Moreover, neurons from clozapine-responsive patients exhibited a reciprocal dysregulation of gene expression, particularly related to glutamatergic and downstream signaling, which was reversed by clozapine treatment. Only neurons from clozapine responders showed return to normal function and transcriptomic profile. Our results underscore the importance of K+ and Na+ channels and glutamatergic synaptic signaling in the pathogenesis of schizophrenia and demonstrate that clozapine might act by normalizing perturbances in this signaling pathway. To our knowledge this is the first study to demonstrate that schizophrenia iPSC-derived neurons exhibit a response phenotype correlated with clinical response to an antipsychotic. This opens a new avenue in the search for an effective treatment agent tailored to the needs of individual patients.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (1). Overall COVID-19-related rates of mortality are low; deaths usually occur in patients older than 60 and those suffering from serious chronic diseases. Most of the patients recover within one or two weeks. However, in approximately 5-10 % of the patients some of the symptoms persist for weeks and months. Post-COVID-19 syndrome is a multisystem disease with overlapping symptoms and may occur even in patients who were relatively mildly affected during the acute phase of the disease. Evaluating the number of patients with or after the novel coronavirus infection in the Czech Republic, it can be estimated that in the next months there will be about 50,000 new patients suffering from long-COVID-19 requiring attention of general practitioners in the least, and, in all probability, also of other medical specialists. A thorough knowledge of the syndrome and efficient ideally evidence-based guidelines have to be formulated to combat the adverse impact of the pandemic.

OBJECTIVES: The aim of this study was to describe the practice of electroconvulsive therapy (ECT) in child and adolescent patients in the Czech Republic. METHODS: We conducted a mail questionnaire survey among Czech facilities associated with the Association of Child and Adolescent Psychiatry, and university hospitals with inpatient psychiatric wards, focused on the practice of ECT between 2013 and 2017 in patients younger than 18 years. RESULTS: Of 18 approached facilities, 13 had access to ECT, and only 6 used ECT on 16 patients. The most common diagnosis was schizophrenia or related disorders (68.75% of patients), and the most common reason for ECT was catatonic symptoms (37.5%). The most common ECT methodology was bitemporal electrode placement with brief-pulse current (62.5%). In 2 patients, ECT was terminated because of ineffectiveness and in 1 patient because of adverse reaction. In other patients, ECT ended after achieving a clinical effect. The most common adverse effect was transient memory impairment in a quarter of the patients. The number of pharmacological treatment attempts before ECT significantly correlated with hospitalization length. CONCLUSIONS: The utilization of ECT among children and adolescents was low. It was usually used in severe conditions after several pharmacological treatment attempts, which may indicate reluctance among providers to use this modality. A number of pharmacological attempts were associated with longer hospitalizations. In the majority of patients, ECT was effective and safe. On the other hand, the monitoring of cognitive adverse effects was insufficient and could be improved.
