Heartfulness Meditation (HFM) in Cyclic Vomiting Syndrome (CVS)
NCT05961995
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 stress exposure. This may reflect an underlying dysfunction of the ECSS in CVS and impaired stress responsivity. Given these data and our preliminary findings of the beneficial effects of HFN meditation, our central hypothesis is that HFN meditation will increase circulating endocannabinoids in CVS and that this will be correlated with a reduction in anxiety and other psychological outcomes and overall quality of life.
We propose to test our hypothesis with the following specific aims
Specific Aim 1a: Conduct a prospective study to elucidate the acute effects of HFN meditation on the ECSS in CVS. We will measure circulating endocannabinoids and related lipids immediately before and after HFN meditation.
1b: Correlate indices of ECSS with state anxiety and mood pre-and post-HFN meditation. We will measure state anxiety and mood with validated tools including the State Trait Anxiety Inventory (STAI) and Profile of Mood States (POMS) which evaluates tension, depression, anger, vigor, fatigue, and confusion.
Hypothesis: HFN meditation will acutely increase circulating endocannabinoids which will be correlated with a reduction in state anxiety and improvement in mood.
Specific Aim 2: Determine the long-term effects of a 6-week HFN meditation program on ECSS and correlate with psychological outcomes including psychological distress, STAI scores, sleep quality, and HRQoL. We will measure these outcomes with validated tools including the Brief Symptom Inventory (BSI), STAI, Pittsburgh Sleep Quality Index (PSQI), and PROMIS quality of life questionnaires.
Hypothesis: A regular HFN meditation practice over 6 weeks will further augment ECSS, and this will be correlated with an improvement in psychological outcomes such as psychological distress, sleep, mood and HRQoL.
