Cannabinoid hyperemesis and the cyclic vomiting syndrome in adults: recognition, diagnosis, acute and long-term treatment.

ABSTRACT: The cannabinoid hyperemesis syndrome (CHS) and the cyclic vomiting syndrome in adults (CVS) are both characterized by recurrent episodes of heavy nausea, vomiting and frequently abdominal pain. Both syndromes are barely known among physicians. Literature is inconsistent concerning clinical features which enable differentiation between CVS and CHS. We performed a literature review using the LIVIVO search portal for life sciences to develop a pragmatic approach towards these two syndromes. Our findings indicate that complete and persistent resolution of all symptoms of the disease following cannabis cessation is the only reliable criterion applicable to distinguish CHS from CVS. Psychiatric comorbidities (e.g. panic attacks, depression), history of migraine attacks and rapid gastric emptying may serve as supportive criteria for the diagnosis of CVS. Compulsive bathing behaviour, a clinical observation previously attributed only to CHS patients is equally present in CVS patients. Long-term follow-up is essential in order to clearly separate CHS from CVS. However, long-term follow-up of CVS and CHS cases is seldom. We provide a standard operating procedure applicable to a broad spectrum of health care facilities which addresses the major issues of CVS and CHS: awareness, diagnosis, treatment, and follow-up.

Project description:Cyclic Vomiting Syndrome (CVS) is an underdiagnosed episodic syndrome characterized by frequent hospitalizations, multiple comorbidities, and poor quality of life. It is often misdiagnosed due to the unappreciated pattern of recurrence and lack of confirmatory testing. CVS mainly occurs in pre-school or early school-age, but infants and elderly onset have been also described. The etiopathogenesis is largely unknown, but it is likely to be multifactorial. Recent evidence suggests that aberrant brain-gut pathways, mitochondrial enzymopathies, gastrointestinal motility disorders, calcium channel abnormalities, and hyperactivity of the hypothalamic-pituitary-adrenal axis in response to a triggering environmental stimulus are involved. CVS is characterized by acute, stereotyped and recurrent episodes of intense nausea and incoercible vomiting with predictable periodicity and return to baseline health between episodes. A distinction with other differential diagnoses is a challenge for clinicians. Although extensive and invasive investigations should be avoided, baseline testing toward identifying organic causes is recommended in all children with CVS. The management of CVS requires an individually tailored therapy. Management of acute phase is mainly based on supportive and symptomatic care. Early intervention with abortive agents during the brief prodromal phase can be used to attempt to terminate the attack. During the interictal period, non-pharmacologic measures as lifestyle changes and the use of reassurance and anticipatory guidance seem to be effective as a preventive treatment. The indication for prophylactic pharmacotherapy depends on attack intensity and severity, the impairment of the QoL and if attack treatments are ineffective or cause side effects. When children remain refractory to acute or prophylactic treatment, or the episode differs from previous ones, the clinician should consider the possibility of an underlying disease and further mono- or combination therapy and psychotherapy can be guided by accompanying comorbidities and specific sub-phenotype. This review was developed by a joint task force of the Italian Society of Pediatric Gastroenterology Hepatology and Nutrition (SIGENP) and Italian Society of Pediatric Neurology (SINP) to identify relevant current issues and to propose future research directions on pediatric CVS.

Project description:IntroductionReddit hosts a large active community of members dedicated to the discussion of cannabinoid hyperemesis syndrome. We sought to describe common themes discussed and the most frequently mentioned triggers and therapies for cannabinoid hyperemesis syndrome exacerbations in the Reddit online community.MethodsData collected from six subreddits were filtered using natural language processing to curate posts referencing cannabinoid hyperemesis syndrome. Based on a manual review of posts, common themes were identified. A machine learning model was trained using the manually categorized data to automatically classify the themes for the rest of the posts so that their distributions could be quantified.ResultsFrom August 2018 to November 2022, 2683 unique posts were collected. Thematic analysis resulted in five overall themes: cannabinoid hyperemesis syndrome-related science; symptom timing; cannabinoid hyperemesis syndrome treatment and prevention; cannabinoid hyperemesis syndrome diagnosis and education; and health impacts. Additionally, 447 trigger and 664 therapy-related posts were identified. The most commonly mentioned triggers for cannabinoid hyperemesis syndrome episodes included: food and drink (n = 62), cannabinoids (n = 45), mental health (e.g., stress, anxiety) (n = 27), and alcohol (n = 22). Most commonly mentioned cannabinoid hyperemesis syndrome therapies included: hot water/bathing (n = 62), hydration (n = 60), antiemetics (n = 42), food and drink (n = 38), gastrointestinal medications (n = 38), behavioral therapies (e.g., meditation, yoga) (n = 35), and capsaicin (n = 29).DiscussionReddit posts for cannabinoid hyperemesis syndrome provide a valuable source of community discussion and individual reports of people experiencing cannabinoid hyperemesis syndrome. Mental health and alcohol were frequently reported triggers within the posts but are not often identified in the literature. While many of the therapies mentioned are well documented, behavioral responses such as meditation and yoga have not been explored by the scientific literature.ConclusionsKnowledge shared via online social media platforms contains detailed information on self-reported cannabinoid hyperemesis syndrome disease and management experiences, which could serve as valuable data for the development of treatment strategies. Further longitudinal studies in patients with cannabinoid hyperemesis syndrome are needed to corroborate these findings.
