• #1 Diagnosis of Cyclic Vomiting Syndrome – NIDDK

  https://www.niddk.nih.gov/health-information/digestive-diseases/cyclic-vomiting-syndrome/diagnosis

  Doctors diagnose cyclic vomiting syndrome based on family and medical history, a physical exam, pattern of symptoms, and medical tests. […] Your doctor may diagnose cyclic vomiting syndrome even if your pattern of symptoms or your child’s pattern of symptoms do not fit the patterns described here. Talk to your doctor if your symptoms or your child’s symptoms are like the symptoms of cyclic vomiting syndrome. […] Doctors use lab tests, upper GI endoscopy, and imaging tests to rule out other diseases and conditions that cause nausea and vomiting. Once other diseases and conditions have been ruled out, a doctor will diagnose cyclic vomiting syndrome based on the pattern or cycle of symptoms.

Cyclic Vomiting Syndrome Diagnostic criteria Must include all of the following: Two or more periods of intense, unremitting nausea and paroxysmal vomiting, lasting hours to days within a 6-month period […] Episodes are stereotypical in each patient […] Episodes are separated by weeks to months with return to baseline health between episodes […] After appropriate evaluation, the symptoms cannot be attributed to another medical condition.

• #1 Cyclic Vomiting Syndrome Clinical Presentation: History

  https://emedicine.medscape.com/article/933135-clinical

  Cyclic vomiting syndrome (CVS) is characterized by recurrent, discrete, stereotypical episodes of rapid-fire vomiting between varying periods of completely normal health. This on-and-off stereotypical pattern of vomiting is nearly pathognomonic of CVS. […] The Rome IV diagnostic criteria for CVS in children include the following, both of which must be met: At least 2 periods of unremitting vomiting with or without retching, lasting hours to days within a 6-month period; A return to the usual state of health that lasts weeks to months. […] Because this 2-episode cutoff resulted in a significant number of misdiagnoses, the guidelines were modified by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) as follows (all criteria must be met): At least 5 episodes, or a minimum of 3 over a 6-month period; Episodic attacks of intense nausea and vomiting lasting 1 hour to 10 days, occurring at least 1 week apart; Stereotypical pattern and symptoms in the individual patient; Vomiting during episodes occurs at least 4 times an hour for at least 1 hour; A return to baseline health during episodes; Symptoms cannot be attributed to another disorder.

• #1 Cyclic vomiting syndrome – Wikipedia

  https://en.wikipedia.org/wiki/Cyclic_vomiting_syndrome

  Cyclic vomiting syndrome (CVS) is a chronic functional condition of unknown pathogenesis. […] The cause of CVS has not been determined and there are no diagnostic tests for CVS. Several other medical conditions, such as cannabinoid hyperemesis syndrome (CHS), can mimic the same symptoms, and it is important to rule these out. If all other possible causes have been excluded, a diagnosis of CVS using Rome criteria by a physician may be appropriate. […] Due to the lack of specific biomarkers available for the disorder, and if all other possible causes can be ruled out (such as intestinal malrotation), physicians rely on the Rome IV process criteria in order to diagnose patients. Patients must meet all three of the following criteria to receive diagnosis: Stereotypical episodes of acute vomiting each with a duration of less than 1 week; A history of at least three discrete episodes in the prior year and at least two episodes in the past 6 months, each occurring at least 1 week apart; An absence of vomiting between episodes, but other milder symptoms can be present between cycles.

  In the evaluation of the patient for possible GI disease, screening blood work should include a complete blood count (CBC) with differential, assessment of the erythrocyte sedimentation rate (ESR), and measurement of levels of hepatic transaminases, pancreatic amylase, and lipase. […] Screening for multiple metabolic and endocrine disorders can be accomplished by assessing pH and measuring levels of electrolytes, glucose, lactic acid, ammonia, amino acids, adrenocorticotropic hormone (ACTH), and antidiuretic hormone (ADH). […] Imaging studies may be indicated as follows. […] Until prospective trials are conducted, the authors current approach generally includes initial blood and urine screens, including metabolic screening and UGI radiography at initial presentation. […] The presence of specific symptoms such as hematemesis, bilious vomiting, persistent headache, flank pain, acidosis, or uncharacteristically severe or atypical vomiting episodes should raise the clinicians index of suspicion of an underlying disorder and should warrant a prompt and more extensive or repeat evaluation.

  https://pmc.ncbi.nlm.nih.gov/articles/PMC5833754/

  Cyclic vomiting syndrome (CVS) is a disorder characterized by episodes of nausea and vomiting lasting for 15 days followed by asymptomatic periods. […] Diagnosis is often delayed with a mean of 15 emergency department (ED) visits prior to identification. […] The diagnostic criteria for adult CVS according to the Rome IV criteria are stereotypic episodes of vomiting with the following characteristics: at least two acute-onset episodes in the past 6 months, each occurring at least 1 week apart, and persisting for less than 1 week. […] The Rome IV workgroup recommends a more extensive diagnostic workup in patient presenting with bilious vomiting, abdominal tenderness, abnormal neurologic findings, or a worsening pattern of vomiting episodes. […] If these tests are unremarkable, consider obtaining a gastric-emptying evaluation. […] The Rome IV workgroup states if severe symptoms persist, antroduodenal or normal manometry can assess for enteric neuropathy or myopathy. […] The Rome IV workgroup cites five studies using two attacks in the past 6 months with adequate specificity to diagnosis.

  Cyclic vomiting syndrome is a poorly understood phenomenon that causes periods of nausea and vomiting alternating with asymptomatic periods. […] Cyclic vomiting syndrome is a diagnosis of exclusion. […] The American Gastroenterological Association suggests a three-step approach to the initial evaluation of nausea and vomiting. […] If no diagnosis is determined after initial evaluation, gastric motility studies (e.g., gastric emptying scintigraphy, cutaneous electrogastrography, antroduodenal manometry) may be considered. However, the utility of such tests is controversial, and many experts suggest a trial of antiemetic or prokinetic medications instead. […] Finally, if all organic, gastrointestinal, and central causes of nausea and vomiting have been explored, psychogenic vomiting should be considered.

  Cyclic vomiting syndrome (CVS) is a potentially exhausting disorder and has an adverse impact on quality of life, but it is poorly recognized and is always misdiagnosed leading to a diagnostic delay of several years, especially in adults. […] Based on typical symptoms and the exclusion of other diseases associated with repeated vomiting, the diagnosis was made as CVS. […] CVS is not rare in adults, but its diagnosis is usually delayed due to poor recognition of the condition. Clinician awareness of CVS should be enhanced to improve early diagnosis. […] The diagnosis of CVS is based on the history and exclusion of other diseases; the Rome IV criteria suggested that expensive and unnecessary investigations should be avoided, because the vast majority (90%) of patients with symptoms consistent with CVS did not have any organ abnormalities on investigation. […] Increased physician awareness could reduce the delayed diagnosis of CVS.

  Cyclic Vomiting Syndrome (CVS) patients also have times where they are feeling sick to the stomach and can also throw up for between 12 hours to about a week. […] Because we do not know a lot about these two problems, your regular doctor may not think about them as a cause of your sickness. This can make it take a long time to figure out what is happening, and it can take around 10 years from the time you start having trouble. […] Most people end up having an abdominal ultrasound, upper scope, and a test to see how fast stuff gets out of the stomach before we figure out that their problem is CVS or CHS. We do these to make sure that nothing really bad is happening. […] So we can figure out if you have CVS or CHS, we look for the below differences. […] The most important thing to make CHS better is stopping marijuana use. Your doctor probably should send you to see a stomach doctor, who knows more about your problem and can help you feel better.

  Cyclic vomiting syndrome (CVS) is a disorder noted for its unique intensity of vomiting, repeated emergency department visits and hospitalizations, and reduced quality of life. […] It is often misdiagnosed due to the unappreciated pattern of recurrence and lack of confirmatory testing. […] The recommended diagnostic approach is to avoid „shotgun” testing and instead to use a strategy of targeted testing that varies with the presence of 4 red flags: abdominal signs (eg, bilious vomiting, tenderness), triggering events (eg, fasting, high protein meal), abnormal neurological examination (eg, altered mental status, papilledema), and progressive worsening or a changing pattern of vomiting episodes. […] This document represents the official recommendations of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition for the diagnosis and treatment of CVS in children and adolescents.

• #1 Cyclical vomiting syndrome: Recognition, assessment and management

  https://www.wjgnet.com/2219-2808/full/v3/i3/54.htm

  Cyclical vomiting syndrome (CVS) is a functional disorder in childhood which is increasingly being recognised. The diagnosis of CVS remains largely one of exclusion. In a child with recurrent vomiting, it is important to rule out life-threatening conditions such as gastro-intestinal structural anomalies including malrotation with volvulus, brain tumours and inborn errors of metabolism. The overall lower frequency of attacks and the higher peak intensity of vomiting in CVS usually allow its distinction from disorders such as bulimia nervosa. While CVS can occur in infants and young children, a diagnosis should be made after a period of observation and careful exclusion of other causes of recurrent vomiting. […] In 2008, the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition appointed a task force to develop a consensus report for CVS to improve the recognition and treatment of this disorder. […] Investigations that are routinely done during the work-up of a child with suspected CVS include both blood and imaging modalities. […] The diagnosis of CVS remains largely one of exclusion.

• #1 Differential Diagnosis of Cyclic Vomiting in Children | AAFP

  https://www.aafp.org/pubs/afp/issues/1999/0201/p675.html

  Cyclic vomiting is defined as episodes of vomiting interspersed with periods of wellness. Patients with cyclic vomiting have at least four episodes of vomiting per hour, but no more than two episodes per week. After testing, no cause of the vomiting is found. […] Li and colleagues conducted a chart review of children who presented with an episodic pattern of vomiting to determine which disorders should be included in the differential diagnosis for a work-up of a child with cyclic vomiting. […] The authors conclude that a rational laboratory evaluation of cyclic vomiting may be initiated based on the results of this study. The tests with the highest yield of positive results in this study were endoscopy and radiography of the sinus and small bowels. More specialized testing, such as determination of blood glucose, electrolytes, liver enzymes, pancreatic enzymes and ammonia levels, should be performed during the vomiting episode, when possible, to maximize the chance of detecting an intermittent or heterozygous disorder. Finally, surgical disorders are best detected by radiographs of the small bowel, abdominal imaging and cranial imaging.

  In adults, much consideration must be used to differentiate CVS from gastroparesis. […] Gastric emptying studies should be performed during the remission phase when there are minimal or no symptoms and no narcotic medications are being received. […] The important message for our clinicians is that CVS can be presented to the patient as a potentially reversible disease: Following initial intensive treatment to achieve remission and after effectively addressing comorbidities, the dose of amitriptyline can be slowly tapered and even stopped over time. […] This is the CVS blue print and epigastric abdominal pain should be added to the Rome criteria for adult CVS patients. […] Finally, CVS patients have either a rapid or normal GE. This is a signature finding separating CVS from gastroparesis and we strongly recommend that GE status be added as one of the major criteria for the diagnosis of CVS.

  Learn how to diagnose and manage cyclic vomiting syndrome (CVS). […] Cyclic vomiting syndrome (CVS) is a chronic disorder of gut–brain interaction characterized by acute episodes of nausea, vomiting, and retching, separated in time by episode-free periods. Individuals with CVS can identify a stereotypic pattern of symptoms that present during both the prodromal and emetic phases. Although there are effective treatments for most patients, the condition remains underdiagnosed and thus undertreated. Most patients experience years of diagnostic delays, extensive and futile investigations, and even unnecessary surgical procedures. Approximately one-half of people with CVS visit the emergency department (ED) at least annually, and 1 in 3 adults with CVS will become disabled. Access to care, early recognition of CVS, and appropriate treatment can reduce CVS symptoms, reduce health care utilization, and improve patients’ quality of life.

  Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction (DGBI) and is characterized by recurrent episodes of severe nausea, vomiting, and often, abdominal pain. Patients are usually asymptomatic in between episodes. […] CVS remains a clinical diagnosis since there are no biomarkers. While there is a lack of data on the optimal work-up in these patients, experts recommend an upper endoscopy or upper GI series in order to rule out alternative gastric and intestinal pathology (e.g., malrotation with volvulus). […] The severity and unpredictable nature of symptoms makes it difficult for some patients to attend school or work; one study found that 32% of patients with CVS were completely disabled. […] Despite increasing awareness of this disorder, patients often are misdiagnosed. The prevalence of CVS in an outpatient gastroenterology clinic in the United Kingdom was 11% and was markedly underdiagnosed in the community.

Your doctor will review your medical and family history, review the cycle of symptoms and may order tests to rule out other diseases and conditions with similar CVS symptoms such as gastroesophageal reflux disease (GERD) and irritable bowel syndrome. […] Tests may include: […] Routine exam: Your doctor will ask you questions about your symptoms and perform a physical exam. This may include a blood or urine test. […] Upper GI endoscopy: A flexible tube equipped with a light and a tiny camera (endoscope) is inserted down the throat to see inside the esophagus and stomach. If needed, a tissue sample (biopsy) can be done during an endoscopy. […] CT scan: This test produces images of your abdomen and digestive system that might rule out other causes of your symptoms.

  Cyclic vomiting syndrome (CVS) is a condition characterized by recurrent, stereotypical bouts of intense vomiting interspersed with periods of completely normal health. […] Treatment of CVS begins with identification of the condition. A distinction is made between chronic vomiting and cyclic vomiting syndrome. Underlying conditions such as gastroesophageal reflux disease (GERD) and sinus infection (sinusitis) should be sought and treated in the patient. […] Not every child requires every medical test. However, if certain warning signs are present the doctor may order one or more tests including: Urinalysis, Upper GI endoscopy, Abdominal ultrasound, Brain CT or MRI, Metabolic blood tests.

  In adults, much consideration must be used to differentiate CVS from gastroparesis. […] Gastric emptying studies should be performed during the remission phase when there are minimal or no symptoms and no narcotic medications are being received. […] The important message for our clinicians is that CVS can be presented to the patient as a potentially reversible disease: Following initial intensive treatment to achieve remission and after effectively addressing comorbidities, the dose of amitriptyline can be slowly tapered and even stopped over time. […] This is the CVS blue print and epigastric abdominal pain should be added to the Rome criteria for adult CVS patients. […] Finally, CVS patients have either a rapid or normal GE. This is a signature finding separating CVS from gastroparesis and we strongly recommend that GE status be added as one of the major criteria for the diagnosis of CVS.

  CVS is a condition that causes you to vomit many times in a row for no known reason. […] Your healthcare provider will examine you and ask about your symptoms. Tell your provider if you have had 3 or more episodes in the past year. Your provider will ask if you or anyone in your family has CVS or migraines. […] Tests may be used to rule out medical conditions that can cause vomiting. An endoscopy is a test that uses a scope to see your stomach and intestines. CT or MRI scans may be used to check for blockages or other problems. A motility test checks how well food moves through your digestive system.

  https://www.aafp.org/pubs/afp/issues/2007/0701/p76.html

  Cyclic vomiting syndrome is a poorly understood phenomenon that causes periods of nausea and vomiting alternating with asymptomatic periods. […] Cyclic vomiting syndrome is a diagnosis of exclusion. […] The American Gastroenterological Association suggests a three-step approach to the initial evaluation of nausea and vomiting. […] If no diagnosis is determined after initial evaluation, gastric motility studies (e.g., gastric emptying scintigraphy, cutaneous electrogastrography, antroduodenal manometry) may be considered. However, the utility of such tests is controversial, and many experts suggest a trial of antiemetic or prokinetic medications instead. […] Finally, if all organic, gastrointestinal, and central causes of nausea and vomiting have been explored, psychogenic vomiting should be considered.

• #2 Cyclic vomiting syndrome: An important differential diagnosis to cannabinoid hyperemesis syndrome | The BMJ

  https://www.bmj.com/content/366/bmj.l4336/rr-1

  We read the article on cannabinoid hyperemesis syndrome (CHS) by Chocron, Zuber Vaucher with great interest. Nonetheless, we would like to emphasize the importance of cyclic vomiting syndrome (CVS) as a differential diagnosis to CHS, especially in patients presenting to emergency departments. Such patients require different pharmacological treatment than patients affected by CHS. […] The clinical differentiation between CVS and CHS can therefore be difficult. However, the intensity of the cannabis use and especially the presence of a trigger for an episode of vomiting can be diagnostic hints. […] According to the Rome IV classification CVS and CHS are both part of the same subgroup, namely subgroup B3: Nausea and vomiting disorders (CVS: B3b, CHS: B3c). […] To fulfill diagnostic criteria of CVS, patients must have had at least two such episodes during the last six months. […] Evidence-based treatment guidelines for CVS were published recently.

  In the evaluation of the patient for possible GI disease, screening blood work should include a complete blood count (CBC) with differential, assessment of the erythrocyte sedimentation rate (ESR), and measurement of levels of hepatic transaminases, pancreatic amylase, and lipase. […] Screening for multiple metabolic and endocrine disorders can be accomplished by assessing pH and measuring levels of electrolytes, glucose, lactic acid, ammonia, amino acids, adrenocorticotropic hormone (ACTH), and antidiuretic hormone (ADH). […] Imaging studies may be indicated as follows. […] Until prospective trials are conducted, the authors current approach generally includes initial blood and urine screens, including metabolic screening and UGI radiography at initial presentation. […] The presence of specific symptoms such as hematemesis, bilious vomiting, persistent headache, flank pain, acidosis, or uncharacteristically severe or atypical vomiting episodes should raise the clinicians index of suspicion of an underlying disorder and should warrant a prompt and more extensive or repeat evaluation.

  Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction (DGBI) and is characterized by recurrent episodes of severe nausea, vomiting, and often, abdominal pain. Patients are usually asymptomatic in between episodes. […] CVS remains a clinical diagnosis since there are no biomarkers. While there is a lack of data on the optimal work-up in these patients, experts recommend an upper endoscopy or upper GI series in order to rule out alternative gastric and intestinal pathology (e.g., malrotation with volvulus). […] The severity and unpredictable nature of symptoms makes it difficult for some patients to attend school or work; one study found that 32% of patients with CVS were completely disabled. […] Despite increasing awareness of this disorder, patients often are misdiagnosed. The prevalence of CVS in an outpatient gastroenterology clinic in the United Kingdom was 11% and was markedly underdiagnosed in the community.

  Cyclic vomiting syndrome (CVS) is a chronic functional condition of unknown pathogenesis. […] The cause of CVS has not been determined and there are no diagnostic tests for CVS. Several other medical conditions, such as cannabinoid hyperemesis syndrome (CHS), can mimic the same symptoms, and it is important to rule these out. If all other possible causes have been excluded, a diagnosis of CVS using Rome criteria by a physician may be appropriate. […] Due to the lack of specific biomarkers available for the disorder, and if all other possible causes can be ruled out (such as intestinal malrotation), physicians rely on the Rome IV process criteria in order to diagnose patients. Patients must meet all three of the following criteria to receive diagnosis: Stereotypical episodes of acute vomiting each with a duration of less than 1 week; A history of at least three discrete episodes in the prior year and at least two episodes in the past 6 months, each occurring at least 1 week apart; An absence of vomiting between episodes, but other milder symptoms can be present between cycles.
