There’s NEVER been a BETTER time to have CVS!

Submitted by: Colleen Rice

Among many support groups for Cyclical Vomiting there is very often a loud call for “FIND A CURE NOW” the pressure from parents asking and sometimes begging make this horrible thing go away. I’ve heard we can send man to the moon but we can’t cure cancer, CVS etc. I like to point out that the common cold has affected more people still has no cure as well. So, here’s my take on why I think there’s never been a better time to have CVS diagnosis.

Recently my 10 year old son and I read”The Apprenticeship of Lucas Whitaker”over Thanksgiving break. As a family we are very much into FIRST Lego League, and we were reading this as part of research for next years WORLD CLASS Challenge. Next years challenge is looking at how kids learn in the 21st century. This book came recommended by our favorite librarian friend, as being a great book that was an example of common ways that children learned in other places and in different ways outside of the classroom. You see, Lucas is the sole survivor in his family as the rest have died from an illness had no cure or as far as anyone knew. He stumbles into a neighboring town lost and looking for direction following his mothers death. He happens to find a sign on a door that says help wanted. lucky he knew how to read, apparently not a common skill in that area. The person looking for the help is a doctor who then take Lucas in as his apprentice.

Why you might be asking why am I bothering to tell you all this. This simple story of a snapshot of American history and culture is classic and a reminder every parent of a sick child needs to remember. In the historical fictional story, you learn the doctor’s sister who used to live in the city, has an obsession with washing which comes across as a mental condition to Lucas. Why was she making him bath everyday in the dead of winter (keep in mind it was the 1800 when there was no easy hot water heater other than a pot of water and a stove ). This sister was in fact ahead of her time, having learned about the importance of washing to avoid illness. Today that sounds like a no brainier….but back then it was groundbreaking that it was revolutionary. It was not that people were dumb, bathing was not a practical thing when you consider the evolution of indoor plumbing and such.

It not difficult when you realize that these people were doing the best with the information they have. There was no internet to google a condition, or even a pediatric specialist of these things to take your child to. Personally, I believe many server cases of CVS in these days probably resulted in death due to dehydration. As a parent of a CVS child, you have seen how fast a child who is retching 10x an hour can dehydrate. We are blessed that we can take our child to a hospital by driving our warm cars in the dead of winter to the local hospital maybe 2 hours away or less… There we meet a team of doctors and nurses who though probably unfamiliar with CVS, can easily spot the need for IV fluids, and also have the supplies readily on hand to administer this life saving treatment to our children.This is a luxury many parents at other times in human history never even had the option of. There has never been a time in history to have CVS.

OK so your thinking, yeah I know we’ve come a long way but everything has… that’s a lifetime ago and I can’t relate to that. Let me tell you another story, my story of what it was like being a child in 1980’s having CVS. Everyone knew when I threw up I never stopped, and dry heaved for hours to the point of bile and would lay there in what I know now to be call a conscious coma. The doctors never knew what to think when my mom brought me. My parents had a friend who was a pharmacist who recommended Emetrol which only seemed to aggravate the vomiting. If I was finally to be admitted to the hospital for this which only happens 3x in my childhood, the nurses would tell my parents I was just being stubborn and I needed to stop. They also pushed fluids orally non stop which as you have come to realize probably is the last thing to do during the height of a cycle.

My parents stopped bringing me to the doctor for it and we always rode it out home which felt like torture. I on some level carried such guilt… why could I not throw up like everyone else? Why would the sound of someone flushing the toilet trigger such horrible retching over and over again? Why could I not swallow or take sips and keep them down like everyone else? The problem must be me…I must be weak or so I’d think to myself every time I got sick. It in no way saying my parents neglectful at all,they did the best the could with the knowledge they had and the resources available to them. The next time we sought treatment for an episode was in 1991 when my kidneys started to shutdown during an episode.

Thankfully after this episode it seems to resolved itself exept for when big life changes occur…such as graduation from college or after my wedding and even those were mild. Then came our first child and for the first time in my life oddly enough, I could puke and be fine! I realized there’s something different going on here.. I can puke and still make dinner and not be down for days. Then our 3rd child was born, and by the time he was 3 I knew he puked like me, but never did I imagine it would progress to the world wind of a thing it’s turned into. I knew when he had his tonsils out he needed to have extra IV fluids to aviod a cycle like I did when I had mine out. But it was not until 2012 that this puking thing had a name, and more than that there were things you could to to help.

So for some the diagnosis of Cyclical Vomiting Syndrome is overwhelming and unfamiliar. For me it was a name to an enemy that plagued my childhood and made me fear vomiting. For me to learn its name and that there was a plan was a time of sheer and utter joy. My son does not have to lay on the floor on the verge of passing out for days, he is blessed to go into the hospital and get the IV fluids and meds needed to stop further damage from being done to his frail and weakened body. He has tears in his stomach from the forceful retching at the tender age of 6. He’s been hospitalized over 20x in his life for this condition in the last 2 years alone. Without these hospitalization, I can say with almost certainty that he would have died long ago if had not been for the medical advances today that many take for granted.

When my son ends up in the hospital, I am nothing but grateful!

There has never been a better time to have CVS.

We don’t have a cure…and I’m OK with that…Because what we do have is a lot!!! We now know more about what it is as a migraine variant. We have drugs we can give to try to reduce severity and frequency. We also know that if all that fails we can give meds and fluids needed to ride out the cycle! These things are a huge step from 30 years ago! I am just starting to learn the mito-component and it again seems like a huge blessing and that we are taking huge steps to a better quality of life for these kids. It will be part of their lives, we can’t change that…. what we can teach them is that they can get through this and that we as caregivers will be there to help. We will continue to seek out answers and better ways to help and minimize CVS’s interruptions in our lives.

Til then It’s Stay Calm and Puke on!


Alyssa’s Story

My daughter, Alyssa, was diagnosed with CVS. Alyssa has always been an over achiever. This year she is attending college her senior year, playing sports such as soccer and softball, and works for the city of recreation doing coaching and ref games. Plus, she was looking for a second job!

Four months ago, when soccer began, she started having this gag reflex. Being a person with exercise induced asthma, we thought it was because she was using her inhaler more. Within 2 months, she started vomiting once a day. At first it we thought it was because she would over eat at dinner. Being on the go a lot, she would skip meals because she didn’t like to eat before practice or a game. She said it would make her a sick. By Thanksgiving and Christmas break, she would vomit after every meal.

We saw her doctor the first week of January. She had weighed 96 lbs. which was a surprise to my daughter. At 4″11 she always weighed around 100-105 when playing sports. Her doctor ran some blood test, but by the end of that week she had dropped down to 86 lbs, and that’s when we had her admitted to the ER.

She was on an IV for a week while they ran every test possible, and yet they still couldn’t find out why she couldn’t hold any food down. A friend told us about CVS, she had found it online. We brought it to the doctors attention, and we asked for them to start her on a white rice diet. At first, only a palm size came up every 10-20 minutes for an hour and then it all started to stay down. Now she is home eating chicken/turkey with rice. Almond milk works; so I make pancakes and try other recipes with it, but not all meals work.

It is definitely a life changing experience. She had to quit soccer, but is hoping to be well enough by softball season.

Cyclic Vomiting Syndrome and Mitochondrial Dysfunction: Research and Treatments

From HORMONES MATTER: Where health and hormones make sense

Cyclic vomiting syndrome (CVS) is a debilitating disease characterized by episodes of severe nausea and persistent vomiting interspersed with periods of wellness. CVS affects about 2 percent of school-aged children, and also affects adults, although in adults it is often not recognized. Getting a diagnosis can be challenging, and sometimes takes a long time. Episodes of CVS can be extremely debilitating, and are sometimes difficult to treat and require hospitalization.

My daughter has suffered from this disease for 10 years, since she was 2 years old (see her story here). Her episodes were somewhat predictable when she was younger, but have changed and become less predictable, and more difficult to manage with medication, as she gets older. Although we try to avoid triggers such as stress and fatigue, being a pre-teen girl, she likes to have sleepovers with her friends and stay up chatting all night.  Unlike other pre-teen girls, however, she suffers the aftereffects of the sleepovers sometimes by vomiting for 24 hours or more.

What Causes Cyclic Vomiting Syndrome?

Although it has long been thought to be related to migraines, many sources state that the cause of cyclic vomiting syndrome is not known. Mechanisms that may be involved include episodic dysautonomia (malfunction of the autonomic nervous system that can result in a variety of symptoms), mitochondrial DNA mutations that cause deficits in cellular energy production, and heightened stress response that causes vomiting. However, there is mounting evidence for the role of mitochondrial dysfunction in the pathogenesis of this disease, a fact that is not often understood by the average practicing gastroenterologist. The connection to mitochondrial dysfunction has important implications for effective treatment of cyclic vomiting syndrome.

Mitochondrial Dysfunction, Cyclic Vomiting and Other Conditions

Mitochondria are small organelles within the cell responsible for energy production and other critical functions. Because of these crucial functions, Dr. Richard Boles, Director of the Metabolic and Mitochondrial Disorders Clinic at Children’s Hospital Los Angeles, explains that “30 years or so ago, many scientists couldn’t believe that mitochondrial disease could exist, because how does the organism survive?” However, mitochondrial dysfunction plays a role in many diseases, including CVS, and according to Dr. Boles:

“these are partial defects. Mitochondrial dysfunction doesn’t really cause anything, what it does is predisposes towards seemingly everything. It’s one of many risk factors in multifactorial disease. It can predispose towards epilepsy, chronic fatigue, and even autism, but it doesn’t do it alone. It does it in combination with other factors, which is why in a family with a single mutation going through the family, everyone in the family is affected in a different way. Because it predisposes for disease throughout the entire system.”

DNA mutations that affect mitochondrial function can occur in the DNA that is found in the nucleus of the cell (genomic DNA), or they can occur in the DNA that is found within the mitochondria themselves. Mitochondrial DNA is inherited differently than nuclear DNA. Most people are familiar with the inheritance of nuclear DNA, in which we have two copies of every gene, and we inherit one copy from each of our parents. However, mitochondrial DNA is inherited exclusively through the mother; therefore, mutations that affect the mitochondrial DNA can be traced through the maternal lineage of a family.

A possible relationship between cyclic vomiting syndrome and mitochondrial dysfunction was suggested by the finding that in some families, CVS was maternally inherited. Mitochondrial DNA mutations and deletions have been reported in patients with CVS, and disease manifestations of mitochondrial dysfunction have been found in the maternal relatives of patients with CVS. In other words, conditions such as migraines, irritable bowel syndrome, depression, and hypothyroidism, are often found in the maternal relatives of patients with CVS.

Mitochondrial DNA mutations don’t cause CVS directly, in the way that a DNA mutation causes cystic fibrosis, for example. In some patients, mitochondrial dysfunction plays a greater role in the causation of their disease, and in other patients, it may be less of a factor. Dr. Boles explains: “In some cases it’s a clear mitochondrial disorder, they have multiple other manifestations and it drives the disease. However, in most patients, it is one of many factors in disease pathogenesis.” Patients with classical mitochondrial disorders have disease manifestations such as muscle weakness, neurological problems, autism, developmental delays, gastrointestinal disorders, and autonomic dysfunction. Some patients with CVS have these other disease manifestations, and some have only CVS symptoms.

Treatment for Cyclic Vomiting Syndrome and Mitochondrial Dysfunction

As with many diseases, understanding as least some of the cause of CVS has allowed for the development of treatments tailored towards fixing the root cause. Co-enzyme Q10 and L-carnitine are two dietary supplements that have been used to treat a wide variety of conditions.  Both supplements may be able to assist the mitochondria with energy production and thus, help compensate for mitochondrial dysfunction. A retrospective chart review study found that using these two supplements, along with a dietary protocol of fasting avoidance (having three meals and three snacks per day), was able to decrease the occurrence of, or completely resolve, the CVS episodes in some patients. In those patients who didn’t respond to treatment with supplements alone, the addition of amitriptyline or cyproheptadine, two medications that have been used for prevention of CVS episodes, helped to resolve or decrease the episodes. Treatment with the cofactors alone was well tolerated with no side effects, and treatment with cofactors plus amitriptyline or cyproheptadine was tolerated by most patients. Therefore effective treatment for prevention of CVS episodes does exist, although it may not be widely employed by most gastroenterologists.

My daughter is currently trying to treat her CVS with the combination of co-enzyme Q10 and L-carnitine. So far she hasn’t experienced any side-effects, and over the next few months we will see if she experiences a decrease or even a complete cessation of her episodes. My hope for her is that she won’t have to choose between missing out on a fun night with her friends, and being able to be functional for the rest of the weekend. Maybe she can be like every other teenager and go to a sleepover, and just be grumpy the next day, instead of spending the next day vomiting and lying on the bathroom floor in pain.
