Ramírez-Pavez TN, Machado-Linde F, García-Peñarrubia P, Nieto-Meca L, Martínez-Esparza M, Marín-Sánchez P. Optimization of peritoneal fluid and leukocyte collection in patients with endometriosis. Fertil Steril 2023; 120:917-919. [PMID: 37392781 DOI: 10.1016/j.fertnstert.2023.06.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 06/20/2023] [Accepted: 06/21/2023] [Indexed: 07/03/2023]
Abstract
OBJECTIVE To propose a standardized protocol for peritoneal free fluid and leukocyte sample collection in women with endometriosis suitable for biomedical research on the basis of the surgical procedure, the clinical and technical conditions, and the quality of the samples obtained. DESIGN Video showing the step-by-step collection procedure and the suitability of samples obtained for biomedical research. SUBJECTS This study included 103 women with confirmed endometriosis by pathology analysis, who signed informed consent and were recruited from the Hospital "Virgen de la Arrixaca", Murcia, Spain. The study was approved by the Ethics Committee of University of Murcia (CEI 3156/2020). MAIN OUTCOME MEASURES We analyzed the presence of free fluid in the peritoneal cavity and its relationship with hormonal treatment intake. In addition, the presence of blood contamination, the number of viable leukocytes and macrophages in free peritoneal fluid and lavages as well as their relationship with the lavage volume used, the body mass index, and the age of patients were analyzed. RESULTS The presence of free peritoneal fluid, in which cells and molecules could be quantified, was scarce in the patients (21%), and it was not significantly related to hormonal treatment intake. The cell viability was higher than 98% in all collected samples; although 54% showed good quality and enough cellularity to be used in biomedical research, 40% were contaminated with blood and 6% had low cellularity. The number of leukocytes and macrophages recovered from the peritoneal lavages correlated positively with the lavage volume used and negatively with the body mass index and was independent of the age of the patients. CONCLUSION We describe a standardized step-by-step procedure for peritoneal fluid and leukocyte collection in women with endometriosis, suitable for biomedical research, taking into account that not all women present free fluid in the peritoneal cavity. We propose to increase the lavage volume recommended by the World Endometriosis Research Foundation from 10 mL to at least 40 mL of sterile saline solution and its mobilization for at least 30 seconds within the peritoneal cavity, especially in patients with higher body mass index, to improve the efficiency of the procedure.

Abstract
The inflammatory response may play a role in depression and the response to antidepressants. Electroconvulsive therapy (ECT), the most acutely powerful antidepressant treatment, can also affect the innate immune system. Here, we determined circulating blood concentrations of the inflammatory mediators C-reactive protein (CRP), IL-1β, IL-6, IL-10, and TNF-α in depressed patients compared to healthy controls and assessed the effect of ECT on their concentrations. Relationships between inflammatory mediator concentrations and mood/cognition scores were also explored. Plasma CRP, IL-1β, IL-6, IL-10, and TNF-α concentrations were examined in 86 depressed patients and 57 controls. Relationships between inflammatory mediators and clinical or cognitive outcomes following ECT were assessed using correlation and linear regression analyzes, respectively. CRP, IL-6, IL-10, and TNF-α were elevated in patients at baseline/pre-ECT compared to controls. However, only IL-6 and TNF-α survived adjustment for potential confounders. IL-1β was undetectable in most samples. ECT did not significantly alter plasma concentrations of any of the inflammatory mediators. No relationship was identified between CRP, IL-6, IL-10, and TNF-α and mood or neurocognitive scores. Overall, our data do not support a major role for these four inflammatory markers in clinical outcomes following ECT or in cognition.

Abstract
ABSTRACT Depression is a major mental health disorder, and its pathophysiology is still largely unknown, as is the action mechanism of electroconvulsive therapy (ECT). Some evidence suggests that inflammation might play a role in depression, and several studies have attempted to demonstrate a link between ECT and cytokines. This systematic review used a qualitative analysis to assess the effect of ECT on inflammatory markers as it relates to the clinical response of depressive symptoms in major depressive disorders. The bibliographic search engines CINAHL, Embase, PsychInfo, and PubMed were used to identify articles published up to July 2020. Search terms related to depression, ECT, and inflammation were used. Descriptive statistical analyses were performed to relate changes in inflammatory markers to clinical response to ECT. Twenty-five studies were included in the analysis. No systematic increases or decreases were found in a given inflammatory marker over the ECT; however, we observed that tumor necrosis factor α and interleukin-6 (IL-6) were more often found to be decreased after ECT, whereas IL-8 and IL-10 were more often found to be increased after treatment. No trend in correlation was found between the degree of clinical improvement of depressive symptoms and the variation of any inflammatory markers, despite positive clinical response to ECT. Great heterogeneity with regard to methodology used and lack of power of the studies included in this review could explain the lack of systematic change and correlation found in this study. Future research conducted on this subject should take into account these methodological limitations to allow subsequent meta-analysis.

Abstract
Purpose The aim of the present article was to briefly summarize current knowledge about the immunomodulatory effects of general anesthetics and the possible clinical effects of this immunomodulation in patients with COVID-19. Methods The PubMed, Scopus, and Google Scholar databases were comprehensively searched for relevant studies. Findings The novel coronavirus causes a wide spectrum of clinical manifestations, with a large absolute number of patients experiencing severe pneumonia and rapid progression to acute respiratory distress syndrome and multiple organ failure. In these patients, the equilibrium of the inflammatory response is a major determinant of survival. The impact of anesthetics on immune-system modulation may vary and includes both pro-inflammatory and anti-inflammatory effects. Implications Inhibition of the development of severe inflammation and/or the enhancement of inflammation resolution by anesthetics may limit organ damage and improve outcomes in patients with COVID-19.

Abstract
Major Depressive Disorder (MDD) is a major contributor to the global burden of disease. Approximately 30-50% of depressed patients fail to reach remission with standard treatment approaches. Electroconvulsive therapy (ECT) is one of the most effective options for these patients. Its exact therapeutic mechanism remains elusive, and reliable predictors of response are absent in the routine clinical practice. To characterize its mode of action and to facilitate treatment decision-making, we analyzed ECT's acute and chronic effects on various immune cell subsets. For this purpose, blood was withdrawn from depressed patients (n=21) directly before and 15 min after the first and last ECT session, respectively. After isolating peripheral blood mononuclear cells, we investigated defined populations of immune cells and their proportional changes upon ECT treatment using flow cytometry. By these means, we found ECT remitters (R; n=10) and non-remitters (NR; n=11) to differ in their relative proportion of putative immunoregulatory CD56highCD16-/dim and cytotoxic CD56dimCD16+ natural killer (NK) cells (CD56highCD16-/dim/CD56dimCD16+: R=0.064(±0.005), NR=0.047(±0.005), p<0.05; linear mixed models) and thus in their NK cell cytotoxicity. NK cell cytotoxicity was further increased after a single ECT session (before=0.066(±0.005), after=0.045(±0.005), p<0.001) and was associated with ECT quality parameters (maximum sustained coherence: r2=0.389, β=-0.656, p<0.001) and long-term BDI-II rating changes (r2=0.459, β=-0.726, p<0.05; both linear regression analysis). To conclude, particular NK cell subsets seem to be involved in ECT's acute effect and its clinical outcome. Due to the limited number of patients participating in our pilot study, future approaches are required to replicate our findings.

Abstract
Objectives: Evidence points towards an important relationship between the antidepressant effects of electroconvulsive therapy (ECT) and the modulation of the immune system. To further elucidate this interplay, we performed a study on the effects of the antidepressant treatment by ECT on 25 cytokines in patients with depression.Methods: We measured 25 different cytokines (interleukin (IL)-1β, IL-1RA, Il-2, IL-2R, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12 (p40/p70), IL-13, IL-15, IL-17, tumor necrosis factor-α, interferon (IFN)-α, IFN-γ, granulocyte-macrophage colony-stimulating factor, macrophage inflammatory protein (MIP)-1α, MIP-1β, IFN-γ-induced protein 10 (IP-10), monokine induced by IFN-γ, Eotaxin, Rantes and monocyte chemoattractant protein 1) in the cerebrospinal fluid (CSF) and blood of 12 patients with a severe and treatment-resistant depressive episode before and after a course of ECT.Results: CSF levels of IP-10, IL-5 and IL-8 were elevated after ECT and more ECT sessions were associated with the differences of CSF levels before and after ECT of IFN-γ, IL-2RA, Rantes, IL-6 and IL-1β. Responders and/or remitters had a decrease of CSF levels of IL-17, MIP-1α, Rantes and IL-2R during ECT. CSF IP-10 levels increased less during ECT in patients who had a remission.Conclusions: Although the sample size was small, we found different effects of the ECT treatment per se and of the antidepressant action induced by ECT in CSF and blood.

Abstract
OBJECTIVES A bidirectional link between the antidepressant effects of electroconvulsive therapy (ECT) and the modulation of the immune system has been proposed. To elucidate the interplay between antidepressant treatment and macrophage/microglia activation in humans, we performed a study on the effects of the antidepressant treatment by ECT on markers of macrophage/microglia activation in patients with depression. METHODS We measured six different markers (IL-6, neopterin, sCD14, sCD163 MIF and MCP1) of macrophage/microglia activation in the cerebrospinal fluid (CSF) and blood of 12 patients with a severe, treatment-resistant depressive episode before and after a course of ECT. RESULTS Some markers in the CSF of remitters were reduced after the ECT course and differed from non-remitters, but no differences were found before and after ECT independently from the antidepressant efficacy. CSF baseline levels of some markers could predict the reduction of depressive psychopathology during ECT. Higher CSF levels indicating increased macrophage/microglia activation at baseline predicted a better treatment response to ECT. CONCLUSIONS Although the sample size was small, our data suggest that macrophages/microglia are involved in the pathophysiology of major depression and that antidepressant efficacy by ECT might be partly explained by the modulation of the innate immune system within the brain.

Abstract
OBJECTIVE Changes in the tumor necrosis factor-α (TNFα) have been associated with major depressive disorder (MDD). Findings concerning the effects of electroconvulsive therapy (ECT) on the TNFα level have been contradictory. The aim was to examine the immediate and long-term changes in the TNFα level and their associations with symptom reduction in patients with MDD during ECT. METHOD The study included 30 patients with MDD. Their TNFα levels were measured at baseline and 2 and 4 hr after the first, fifth and last ECT session. Depressive symptoms were assessed with the Montgomery-Asberg Depression Rating Scale (MADRS). RESULTS The TNFα level decreased from baseline to the 2- and 4-hr measurements. There was a correlation between the first ECT session TNFα levels and the relative symptom reduction according to the MADRS score after the ECT series. Both the first (baseline) ECT and 4-hr TNFα levels were lower in responders than in nonresponders. CONCLUSION ECT consistently induced a decrease in the TNFα level after each studied session. A low TNFα level at the first ECT appeared to predict a symptom reduction. These findings suggest that TNFα might have a role in the pathogenesis in MDD and in the mechanism of action of ECT.

Electroconvulsive therapy enhances the anti-ageing hormone Klotho in the cerebrospinal fluid of geriatric patients with major depression. Eur Neuropsychopharmacol 2018; 28:428-435. [PMID: 29274997 DOI: 10.1016/j.euroneuro.2017.12.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Revised: 10/25/2017] [Accepted: 12/06/2017] [Indexed: 02/06/2023]
Abstract
Klotho is a humoral factor with pleiotropic effects. Most notably, Klotho deficiency is associated with a phenotype comprising organ manifestations accompanying aging including atherosclerosis and cognitive impairment. Research on the role of Klotho in affective disorder is scarce, which is surprising in light of the fact that depression is associated with accelerated cellular aging as well as aging-related phenotypes and comorbidity observed in Klotho deficiency. On these grounds we investigated Klotho levels in the cerebrospinal fluid (CSF) and serum of eight geriatric patients undergoing electroconvulsive therapy (ECT) for severe depression. We hypothesize that ECT as a highly effective antidepressant treatment leads enhances Klotho levels. We found a significant difference between pre- and post-ECT CSF Klotho (792.5pg/ml vs. 991.3pg/ml, p=0.0020), but no difference in serum Klotho (602.5 vs. 594.3, p=0.32). Moreover, CSF Klotho increase positively correlated with the number of single ECT sessions that were performed in each patient (F1, 6)=7.84, p=0.031). Conjointly, the results of our exploratory study with a small sample size suggest a central nervous system-specific impact of ECT on Klotho, which may in turn partake in mediating the antidepressant effect of ECT. We suggest the modulation of neuroinflammatory processes, which have been ascribed pathophysiological relevance within the conceptual framework of the neuroinflammation hypothesis of depression, through ECT as a potential mechanism by which Klotho is enhanced in response to treatment. Further preclinical and clinical investigation should aim for a precise identification of the role of Klotho in depressive disorder.

Abstract
Major depressive disorder (MDD) is a complex and multi-factorial disorder. Although genetic factors and other molecular aspects of MDD have been widely studied, the underlying pathological mechanisms are still mostly unknown. We sought to investigate the pathophysiology of MDD by identifying and characterising serum molecular differences and their correlation to symptom severity in first onset, antidepressant drug-naïve MDD patients. We performed an exploratory molecular profiling study on serum samples of MDD patients and controls using multiplex immunoassay and label-free liquid chromatography mass spectrometry in data independent mode (LC-MSE). We included two independent cohorts of first onset, antidepressant drug-naïve MDD patients (n = 23 and 15) and matched controls (n = 42 and 21) in our study in order to validate the results. The main outcome included the following list of circulatory molecules changing and/or correlating to symptom severity: angiotensin-converting enzyme, acute phase proteins (e.g. ferritin and serotransferrin), brain-derived neurotrophic factor, complement component C4-B, cortisol, cytokines (e.g. macrophage migration inhibitory factor and interleukin-16), extracellular newly identified receptor for advanced glycosylation end products-binding protein, growth hormone and superoxide dismutase-1. This study provides evidence of an increased pro-inflammatory and oxidative stress response, followed by a hyperactivation of the HPA-axis in the acute stages of first onset MDD, as well as a dysregulation in growth factor pathways. These findings help to elucidate MDD related pathways in more detail and further studies may lead to identification of novel drug targets, including components of the inflammatory and oxidative stress response.

Abstract
Objective To standardize the recording of surgical phenotypic information on endometriosis and related sample collections obtained at laparoscopy, allowing large-scale collaborative research into the condition. Design An international collaboration involving 34 clinical/academic centers and three industry collaborators from 16 countries. Setting Two workshops were conducted in 2013, bringing together 54 clinical, academic, and industry leaders in endometriosis research and management worldwide. Patient(s) None. Intervention(s) A postsurgical scoring sheet containing general and gynecological patient and procedural information, extent of disease, the location and type of endometriotic lesion, and any other findings was developed during several rounds of review. Comments and any systematic surgical data collection tools used in the reviewers' centers were incorporated. Main Outcome Measure(s) The development of a standard recommended (SSF) and minimum required (MSF) form to collect data on the surgical phenotype of endometriosis. Result(s) SSF and MSF include detailed descriptions of lesions, modes of procedures and sample collection, comorbidities, and potential residual disease at the end of surgery, along with previously published instruments such as the revised American Society for Reproductive Medicine and Endometriosis Fertility Index classification tools for comparison and validation. Conclusion(s) This is the first multicenter, international collaboration between academic centers and industry addressing standardization of phenotypic data collection for a specific disease. The Endometriosis Phenome and Biobanking Harmonisation Project SSF and MSF are essential tools to increase our understanding of the pathogenesis of endometriosis by allowing large-scale collaborative research into the condition.

Abstract
Electroconvulsive therapy (ECT) is mainly used to treat medication resistant major depressive disorder (MDD) patients, with a remission rate of up to 90%. However, little is known about the serum molecular changes induced by this treatment. Understanding the mechanisms of action of ECT at the molecular level could lead to identification of response markers and potential new drug targets for more effective antidepressant treatments. We have carried out a pilot study which analysed serum samples of MDD patients who received a series of ECT treatments over 4 weeks. Patients received only ECT treatments over the first two weeks and a combination of ECT and antidepressant drugs (AD) over the subsequent two weeks. Blood serum analyses were carried out using a combination of multiplex Human MAP® immunoassay and liquid-chromatography mass spectrometry (LC-MS(E)) profiling. This showed that ECT had a predominant acute effect on the levels of serum proteins and small molecules, with changes at the beginning of ECT treatment and after administration of the ECT+AD combination treatment. This suggested a positive interaction between the two types of treatment. Changed molecules included BDNF, CD40L, IL-8, IL-13, EGF, IGF-1, pancreatic polypeptide, SCF, sortilin-1 and others which have already been implicated in MDD pathophysiology. We conclude that ECT appears to exert mainly acute effects on serum molecules.

Abstract
The process of protein phosphorylation in cells is well studied in the context of a wide range of biologic functions such as signalling, cell cycle, cell growth and differentiation, and others. In contrast, little progress has been made in the investigation of protein phosphorylation specifically in blood. Here, we focussed on the phosphoproteome in human blood serum to study its extent and characteristics, and to explore the potential clinical utility. Immobilised metal ion affinity chromatography (IMAC) for the enrichment of intact phosphorylated proteins and label-free liquid chromatography-mass spectrometry (LC-MS(E)) were used for the molecular analysis of a large number of serum samples. To obtain high-confidence results, phosphorylated peptides had to be detected in at least 2 out of 3 technical replicates per sample and in >70% of the serum samples drawn from 80 volunteers. Individual analysis of these 80 non-pooled samples resulted in the detection of 5825 unique phosphorylated peptides after filtering, which corresponded to 502 unique proteins. The results provided evidence that blood serum may be an untapped source of phosphoproteins suitable for potential use in understanding disease pathophysiology and for identification of disease and drug response biomarkers. This article is part of a Special Issue entitled: Integrated omics.
