Heartfulness Meditation (HFM) in Cyclic Vomiting Syndrome (CVS)

Study Summary

Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction (DGBI) characterized by episodes of vomiting often triggered by stress. CVS affects 2% of the population and has a disproportionate negative impact on patients and the healthcare system. Although gastrointestinal symptoms are prominent, most patients have comorbid anxiety, depression, high degrees of psychological distress, and other negative cognitive traits that adversely affect health-related quality of life (HRQoL). This is independent of typical measures of severity of CVS and warrants treatment. Recent guidelines recommend a biopsychosocial model of care incorporating techniques like meditation to mitigate stress and improve psychological outcomes in CVS. One potential approach to improve these outcomes is the use of heartfulness (HFN) meditation. Heartfulness meditation is a secular, specific, guided meditation technique that includes progressive relaxation with a concentrated focus on the heart. It is offered virtually and is free-of charge ensuring no barriers to broad application in clinical practice. A pilot study incorporating HFN meditation in CVS significantly reduced psychological distress, perceived stress, and improved coping strategies, sleep quality, and HRQoL. Other data also show that HFN meditation improves overall well-being and reduces perceived stress. However, there are significant gaps in our understanding of the mechanism underlying HFN meditation and its effects on patient outcomes. The endocannabinoid signaling system (ECSS) is activated by stress exposure and functions through multiple neuroendocrine responses to mitigate the negative effects of stress. We examined the role of the ECSS in CVS and found that endocannabinoids were not elevated during an acute CVS episode. This lack of a response in the ECSS during an acute CVS episode, which is characterized by panic, intense nausea and vomiting is striking, given that the ECSS is typically activated by stres

Primary Outcome

The primary outcomes were state and trait anxiety and mood states, measured using the State-Trait-Anxiety Inventory (STAI) and Profile of Mood States (POMS) respectively. The STAI-S evaluates current feelings of apprehension, tension, nervousness, and worry. The scale consists of two 20-item subscales and four rating categories including very much so, moderately so, somewhat and not at all. Scores for STAI range from 20 to 80. Higher scores indicate great anxiety, lower scores indicate no or low
