Inflammatory cytokines and depression symptoms following hematopoietic cell transplantation.

Increased synthesis and release of inflammatory signalling proteins is common among individuals with hematologic malignancies undergoing hematopoietic cell transplantation (HCT) due to intensive conditioning regimens and complications such as graft-versus-host-disease and infections. Prior research indicates that inflammatory responses can activate central nervous system pathways that evoke changes in mood. This study examined relationships between markers of inflammatory activity and depression symptoms following HCT. Individuals undergoing allogeneic (n = 84) and autologous (n = 155) HCT completed measures of depression symptoms pre-HCT and 1, 3, and 6 months post-HCT. Proinflammatory (IL-6, TNF-α) and regulatory (IL-10) cytokines were assessed by ELISA in peripheral blood plasma. Mixed-effects linear regression models indicated that patients with elevated IL-6 and IL-10 reported more severe depression symptoms at the post-HCT assessments. These findings were replicated when examining both allogeneic and autologous samples. Follow-up analyses clarified that relationships were strongest for neurovegetative, rather than cognitive or affective, symptoms of depression. These findings suggest that anti-inflammatory therapeutics targeting an inflammatory mediator of depression could improve quality of life of HCT recipients.

Psychological and physical function in allogeneic hematopoietic cell transplant survivors with chronic graft-versus-host disease.

PURPOSE: Chronic graft-versus-host disease (cGVHD) is a common late complication of allogeneic hematopoietic cell transplantation (HCT). This study comprehensively evaluated physical and psychological function among individuals with cGVHD. Additional aims were to investigate relationships between disease severity and psychological and physical function, and to investigate patterns of psychological and physical function by disease site. METHOD: Adults at least 6 months post allogeneic HCT were enrolled and either had cGVHD (n =59) or served as a reference sample of HCT survivors with no cGVHD history (n = 19). Participants completed self-report measures of depression, anxiety, fatigue, insomnia, pain, cognition, and sexual function and had a comprehensive clinical evaluation of cGVHD using NIH consensus scoring criteria. Participants with cGVHD were stratified by disease severity and site and compared to the reference group with no cGVHD. RESULTS: Participants with mild cGVHD had comparable psychological and physical symptoms to the reference sample, while participants with moderate cGVHD experienced more severe anxiety and problems with sexual function, and participants with severe cGVHD experienced more severe depressive symptoms and pain compared to the reference sample. Participants with cGVHD manifesting in the skin and GI tract had the most severe symptoms, including mood disturbance, fatigue, and pain. CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS: Results suggest that patients with more severe cGVHD and those with cGVHD manifesting in the skin, GI tract, and lungs are at risk for poorer psychological and physical outcomes and may benefit from proactive interventions to optimize function.

Impact of the COVID-19 pandemic on cancer patients and psycho-oncology providers: Perspectives, observations, and experiences of the American Psychosocial Oncology Society membership.

OBJECTIVE: To understand: (1) psycho-oncology providers' perspectives on and observations of the psychological responses of their cancer patients during the pandemic, and (2) psycho-oncology providers' own experiences delivering care. METHODS: In this concurrent mixed methods study, a survey was distributed to psychosocial providers who were members of the American Psychosocial Oncology Society (APOS). Survey respondents were invited to participate in a one-on-one audio-recorded interview via phone or secure Zoom®. RESULTS: seventy-six self-identified psycho-oncology providers responded to the survey and 11 participated in a one-on-one interview. Approximately half reported that patients responded in unique ways to COVID-19 stress relative to other populations. Three themes emerged from qualitative analyses: (1) unique burden on patients, (2) cancer patients' pandemic response and its relationship to their cancer experience, and (3) unexpected positive changes. Providers emphasized that the cancer experience may have prepared patients for the existential distress of the pandemic and described patients' resiliency. Two themes emerged regarding delivery of care: (1) new professional and personal challenges and (2) provider resiliency. CONCLUSIONS: Although providers observed that the pandemic placed new burdens on patients, they emphasized that the cancer experience may have prepared patients for the existential distress of the pandemic and described patients' resiliency. To overcome challenges, psycho-oncology providers used innovative strategies to support patients and foster their own mental health.

Biobehavioral Research and Hematopoietic Stem Cell Transplantation: Expert Review from the Biobehavioral Research Special Interest Group of the American Society for Transplantation and Cellular Therapy.

Hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for many hematologic conditions. Despite advances in conditioning and supportive measures, however, there remain significant comorbidities that threaten survivorship. Adverse effects of stress-related biobehavioral processes-defined here as the interactions of behavioral, psychological, and socioenvironmental factors with biology-impact immune recovery and function and are particularly salient in the HCT context, given the importance of immune reconstitution for improved survivorship. However, biobehavioral processes have been underinvestigated in this vulnerable group compared with other cancer populations. Here the Biobehavioral Research Special Interest Group (SIG) of the American Society for Transplantation and Cellular Therapy provides an expert review to inform research directions explicating the biological correlates of behavioral symptoms and evaluate the impact of these on HCT outcomes. The goal of this expert review is to provide a foundation for advancing science that effectively integrates behavioral and biological processes to optimize quality of life and improve clinical outcomes for HCT recipients.

Mindfulness, Experiential Avoidance, and Recovery From Hematopoietic Stem Cell Transplantation.

BACKGROUND: Mood disturbance, pain, and fatigue are prevalent and distressing concerns for patients with hematologic cancer recovering from hematopoietic stem cell transplantation (HSCT). The way in which individuals approach difficult thoughts and emotions may affect symptoms and functioning. Specifically, mindfulness has been associated with more optimal psychological and physical functioning, whereas experiential avoidance has been associated with poorer outcomes. PURPOSE: The primary objective was to determine whether mindfulness and experiential avoidance measured prior to HSCT were associated with recovery of psychological and physical functioning following HSCT. We also evaluated dimensions of mindfulness to determine which were most robustly associated with outcomes. METHODS: Participants completed measures of mindfulness and experiential avoidance prior to HSCT. Depression and anxiety symptoms and pain and fatigue interference with daily activities were assessed prior to HSCT and 1, 3, and 6 months post-HSCT. RESULTS: Participants who reported better ability to describe their internal experiences and who were better able to act with awareness experienced less depression, anxiety, and fatigue interference following HSCT. Participants who were nonjudgmental and nonreactive toward thoughts and emotions experienced less depression and anxiety following HSCT, but these traits were not associated with pain or fatigue interference. Being a good observer of internal experiences was not associated with outcomes, nor was experiential avoidance. CONCLUSIONS: Results suggest that most facets of mindfulness may optimize psychological functioning following HSCT, and the ability to describe one's internal experience and to focus on the present moment may have a beneficial influence on physical functioning.
