Abstract
Secondary pharmacology screening of investigational small-molecule drugs for potentially adverse off-target activities has become standard practice in pharmaceutical research and development, and regulatory agencies are increasingly requesting data on activity against targets with recognized adverse effect relationships. However, the screening strategies and target panels used by pharmaceutical companies may vary substantially. To help identify commonalities and differences, as well as to highlight opportunities for further optimization of secondary pharmacology assessment, we conducted a broad-ranging survey across 18 companies under the auspices of the DruSafe leadership group of the International Consortium for Innovation and Quality in Pharmaceutical Development. Based on our analysis of this survey and discussions and additional research within the group, we present here an overview of the current state of the art in secondary pharmacology screening. We discuss best practices, including additional safety-associated targets not covered by most current screening panels, and present approaches for interpreting and reporting off-target activities. We also provide an assessment of the safety impact of secondary pharmacology screening, and a perspective on opportunities and challenges in this rapidly developing field.

Abstract
COVID‐19 and ME/CFS present with some similar symptoms, especially physical and mental fatigue. In order to understand the basis of these similarities and the possibility of underlying common genetic components, we performed a systematic review of all published genetic association and cohort studies regarding COVID‐19 and ME/CFS and extracted the genes along with the genetic variants investigated. We then performed gene ontology and pathway analysis of those genes that gave significant results in the individual studies to yield functional annotations of the studied genes using protein analysis through evolutionary relationships (PANTHER) VERSION 17.0 software. Finally, we identified the common genetic components of these two conditions. Seventy‐one studies for COVID‐19 and 26 studies for ME/CFS were included in the systematic review in which the expression of 97 genes for COVID‐19 and 429 genes for ME/CFS were significantly affected. We found that ACE, HLA‐A, HLA‐C, HLA‐DQA1, HLA‐DRB1, and TYK2 are the common genes that gave significant results. The findings of the pathway analysis highlight the contribution of inflammation mediated by chemokine and cytokine signaling pathways, and the T cell activation and Toll receptor signaling pathways. Protein class analysis revealed the contribution of defense/immunity proteins, as well as protein‐modifying enzymes. Our results suggest that the pathogenesis of both syndromes could involve some immune dysfunction.

Abstract
BACKGROUND Indolent systemic mastocytosis (ISM) is characterized by pathological accumulation of mast cells. The mechanism behind its phenotypic heterogeneity is not well understood. Interaction of mast cells with other immune cells might cause systemic inflammation and thereby associated symptoms. OBJECTIVE To investigate peripheral leukocyte compartments and serum immune proteome in ISM. METHODS Peripheral blood leukocyte phenotyping using flowcytometry in a cohort of 18 adults with ISM and 12 healthy controls. Targeted proteomics was performed to measure 169 proteins associated with inflammation on serum of another 20 ISM patients and 20 healthy controls. RESULTS Proportions of plasmacytoid dendritic cells (pDC) and monocytes were significantly decreased while T-helper 2 cells were increased in peripheral blood of ISM patients. Furthermore, a shift from naïve to memory T-cells was observed. Hierarchical clustering of the serum proteome revealed two distinct subgroups within ISM patients. In subgroup A (n=8), 62 proteins were significantly overexpressed, whereas subgroup B (n=12) was comparable to healthy controls. Patients in subgroup A displayed upregulated signaling pathways downstream of Toll-like receptor 4, TNF-α and interferon-γFatigue was more often present in subgroup A compared to B (75% vs. 33% respectively, p 0.06). CONCLUSIONS Altered distribution of leukocyte subsets and a pro-inflammatory proteome were observed in subsequent two cohorts of ISM patients. We hypothesize that neoplastic mast cells recruit and activate pDC, monocytes and T-cells leading to a vicious cycle of inflammation. CLINICAL IMPLICATION Characterization of inflammatory mechanisms in ISM might uncover additional targets for treatment, in particular for constitutional symptoms such as fatigue.

Abstract
Mastocytosis is an orphan disease associated with many systemic symptoms, chronic handicap, and potentially marked social consequences despite improved therapies. In this study, the authors aimed to measure the effect of 2 hypnosis sessions on mastocytosis symptoms in a clinical setting. Questionnaires (pain, flushes, energy, digestive symptoms, quality of life, perceived symptom severity, and global impression of change) were completed pre- and posthypnosis intervention. Data from 20 patients were analyzed (mean age: 53.3 years, 75% female). Compared to baseline assessment, patients exhibited a significant improvement immediately after the first and second hypnosis sessions with regard to the number of days with abdominal pain, abdominal pain intensity and fatigue (p = .03 and p = .005; p = .05 and p = .02; p = .034, and p = .039, respectively). Perceived severity of symptoms was significantly improved throughout the study (p = .0075). Long-term improvement in global impression of change was observed in half the responders (8/16). Patients with mastocytosis had an improvement in disabling symptoms with the impact of hypnotic intervention persisting at 1 month. Several patients experienced long-term improvement.

Abstract
BACKGROUND Psychological symptoms appear to be frequent among patients with mastocytosis and can significantly affect patient quality of life. However, it remains unclear whether and to which extent this may be the case. OBJECTIVE To investigate he presence and type of psychological symptoms and quality of life in patients with mastocytosis. METHODS In this cross-sectional cohort study of adult patients with mastocytosis, all patients completed the 36-item Short Form Health Survey (SF-36) and the 90-item Symptom Checklist (SCL-90). Results were compared with those of a healthy groups of patients with other diseases (chronic pain and cancer) and healthy populations. RESULTS Fifty patients were included in the study. Seventy percent had indolent systemic mastocytosis. Patients with mastocytosis scored significantly worse than a healthy norm group on the total SCL-90 and more specifically on the dimensions of depression, somatization, sleeping problems, and inadequacy of acting and thinking. Strikingly, patients with mastocytosis scored similarly to patients with cancer on the SF-36 subdomains of general health perception and vitality. However, no significant difference in the mental health subdomain of the SF-36 was found when compared with a healthy group. CONCLUSION In addition to the presence of psychological symptoms, the physical symptoms that are associated with mastocytosis also have a significant impact on the quality of life of patients with this disease. Therefore, correct treatment through symptom control and psychological counseling is necessary. TRIAL REGISTRATION EudraCT Identifier 2015-004604-37.

Abstract
PURPOSE The aim of this study was to evaluate the effects of a dietary supplement containing primarily an extract of salmon's milt (semen) on symptoms and blood levels of proinflammatory molecules in patients with fibromyalgia syndrome (FMS), a chronic, painful musculoskeletal disease without a distinct pathogenesis or treatment. We recently reported increased serum levels of the proinflammatory molecules substance P (SP) and tumor necrosis factor (TNF) in patients with FMS as compared to those in normal controls. METHODS This prospective, open-label study was conducted in patients with FMS (n = 87; 80 women, 7 men; age range, 18-80 years) selected from 2 clinical centers in Spain. Patients were administered the supplement and were evaluated at weeks 1 (before treatment), 4, 8, and 12 (end of treatment) for clinical parameters of functioning, fatigue, and pain, as well as overall impression. Patients were directed to take 1 capsule per day in the morning for the first 4 weeks, followed by 1 capsule in the morning and 1 capsule in the evening for the remaining 8 weeks. Differences in symptom scores in patients with FMS between weeks 1 and weeks 4, 8, and 12 were evaluated using ANOVA. Blood was obtained and serum separated in patients with FMS at 1 and 12 weeks and in a separate population of healthy controls (n = 20; 15 women, 5 men; age range, 25-65 years). Serum levels of SP and TNF were measured in patients with FMS at 1 and 12 weeks and in healthy controls by ELISA. TNF and SP levels in patients with FMS were compared between weeks 1 and 12, as well as between patients with FMS and untreated controls, using the Mann-Whitney U test. FINDINGS Clinical parameters of functioning, fatigue, and pain, as well as overall impression, were improved significantly at 4 weeks as compared to 1 week and remained unchanged for the duration of the study (all, P < 0.0001). Serum TNF and SP levels were significantly elevated at 1 week in patients with FMS compared to controls and were decreased significantly at 12 weeks as compared to 1 week (all, P < 0.0001). IMPLICATIONS Our findings indicate that this dietary supplement may significantly improve symptoms in patients with FMS. This is the first time to our knowledge that any molecule has been reported to be associated with a reduction in serum SP level. Consequently, the supplement or its hypothesized main active ingredient, spermine, may be developed as a novel treatment approach to FMS or other neuroinflammatory conditions.
