Emergency Preparedness Plans for ME/CFS and FM Patients

Living in New England or other parts of the country where weather tends to be unpredictable and often severe, it is essential that people with chronic illnesses and health problems make it a habit to prepare themselves for emergencies. Most of these will be weather-related but difficult situations, like loss of electricity, heat and water can last longer than expected.


As patients with a chronic illness, being prepared as much as possible is key to reducing the stress that comes from lack of preparation. It is no secret that stress is not our friend, especially if you have Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) or Fibromyalgia (FM).

This article is a detailed outline of what to prepare for so you don't have to think. However, keep in mind that each individual person may have to personalize the list. And in no way does it cover absolutely everything. Feel free to add your particulars to the list.

Contact your county government's emergency information management office and see what they have to offer for planning resources.

If you use services from your state, county or city as a disabled person, such as meals-on-wheels or home aid, contact them and ask what services they provide in an emergency and see if they maintain a list of disabled people on which you can be put. In a disaster, this means someone would be looking for you.


What to keep in your car

For automobiles: there are some specific things to keep in the car either for emergencies or for inclement weather, especially when we start another unpredictable winter in New England:

  • Your name, address, phone, work and home, emergency contact numbers and your physician's name, address and phone. You may want to include your date of birththis can be a written list you keep on your person
  • Window brush and/or scraper
  • Bag of icemelt (cheap brands don't work as well)
  • Roll of paper towels
  • Small shovelcan have the fold up handle or be a child's plastic shovel
  • Car cell phone charger, if you have a cell phone
  • Flashlight with batteries and make sure it is in working order
  • Portable radio with batteries
  • Emergency lights
  • A few plastic forks, spoons and knives, bendable straws
  • Maps of the areas you travel the most
  • An extra fleece coat or jacket because fleece keeps you warm
  • Extra pair of gloves
  • Warm hat
  • A few bags of dried food that has a long shelf life
  • Emergency blanket such as a sheet of mylar that is lightweight but can keep you warm. It might be a good idea to include one in the emergency kit for your home

    • Large sterile gauze pads
    • Paper tape in a wider size so it can be can into smaller pieces if necessary
    • Scissors (to cut clothes, gauze etc.)
    • Assortment of stiri-strips and band aids
    • Ace bandage
    • Aspirin
    • Face mask
    • Benadryl for itch and allergy relief
    • Non-latex gloves (preferably several pairs)
    • Pain medicine if you have extra
    • Something to make a tourniquet
    • Drinking water
    • Small but warm blanket
    • A tarp
    • Hand warmers that when snapped, heat up
    • Whistleso people can find you

     

     


For your home or apartment

Depending on space, this may have to be adjusted. Plan on having at least a 3-day supply of food. As we have seen, outages can last for longer, so being prepared is important.

First, have a plan

  • First and foremost have a plan with the residents of your home where to meet outside the home should you have to leave quickly (as in fire, etc). If children are involved, practice this plan

What to put in an emergency grab bag— documentation

  • Emergency Grab Bag of Documentation comprising of important papers (ask yourself "if I had to start life over, what would I need?"). This should be done for each person in the household, including children and pets. Make copies of all important papers/bills/documentation and put them in the largest ziplock bag (waterproof) and keep them in an emergency grab area BEFORE you will need them.

    Information can be coordinated into groups. Check off as you go along.

Contact Lists

Checklist of supplies that you should have readily available

Food and Kitchen Supplies:

  • A number of foil pans
  • A metal frame used to hold the pans (used for cooking)
  • Several cans of sterno for cooking
  • Manual can opener, preferably the type that uncrimps the can and leaves no sharp edges or food contamination
  • Bottle opener
  • Flame lighter
  • Several books of matches or a box of kitchen matches (they are longer than books of matches) kept in a dry, waterproof container or a sealed plastic bag
  • Box of zip-lock freezer bags in quart and gallon size—if possible, try to have the 2 ½ gallon size (made by Hefty brand)
  • Heavy duty aluminum foil
  • Canned food or dried food has a longer shelf life. Items such as tuna fish, cereal and black beans and items such as nutella do not need to be heated. Nutella is a chocolate spread that does not need refrigeration and can be found in the grocery store near the peanut butter. Spread on rice cakes, English muffins or toast, it is breakfast. Canned soup is also a good storage item. There are a number of single serving items which would eliminate the issue of what to do with leftovers. Fruit and pudding items such as applesauce, fruit cocktail, pineapple, chocolate pudding etc., come in either small cans or single serving sizes and do not need refrigeration. Various nuts have nutritional value and can be easily stored. Milk is available in either the dried variety, or boxed style. One variety is called Parmalat, which is an ultra pasteurized 100% cow's milk, and can be stored on a shelf for up to 6 months. There is always the peanut butter staple. Food bars are another item that can be stored. They tend to be a bit expensive, but can give you a boost when you really need it. Pay attention to expiration dates on everything including the water. Replace as necessary, or no later than 6 months. Label and date all food as you bring it in. If storing dried food such as cereal, pasta, or nuts, store in a plastic air-tight container to avoid rodent or insect issues
  • Reusable cold compresses—if you keep several of these in various sizes in your freezer, other than the medical use, they come in handy if you need to toss them into the cooler.
  • A cooler. The old fashion hard shell type works well (also works as additional seating) but the newer soft sided ones with the thermal insulated lining will keep things cold for a very long time. If a storm hits, and you lose electricity, throw the perishables into the cooler. You can use snow inside the cooler if you don't have enough ice. Should you lose electricity, do not repeatedly open your freezer or refrigerator door. Take out what goes into a cooler and then keep the door closed. Things could last 2-3 days this way. When cleaning out after the fact, if in doubt, throw it out.
  • If you are diabetic or have other medical/nutritional needs, then it is important and necessary that you plan and make proper preparations ahead of time.
  • Paper plates, plastic cups, forks, spoons and knives and napkins
  • Mess kit
  • Cooking utensils
  • Small camp stove or gas grill used outside the home (also fuel for use)
  • Several gallons of commercially filled water jugs per person and pet per day. If you fill containers yourself, make sure they are sanitized and use a food-grade container which can be found at camping supply stores. The Centers for Disease Control and Prevention (CDC) recommends at least one gallon per day but that is for drinking water only, not cleaning or bathing. If there is room to store 2 weeks worth of supplies, it is a good idea to do so.
  • Fire extinguisher should be kept near or in the kitchen

Household Supplies:

  • If possible, a gas-run generator. This is only applicable to single households, and not appropriate for individual apartments. Propane gas can only be stored in a garage or outdoors, NOT inside a home
  • Extra toilet paper
  • Extra paper towels
  • Dishwashing liquid and /or bar of soap
  • A large bottle of unscented liquid chlorine bleach for sanitizing and disinfecting water, should it be necessary. To sanitize containers, use 1 teaspoon bleach to one quart of water
  • Medicine dropper—when diluted nine parts water to one part bleach, bleach can be used as a disinfectant. Or in an emergency, you can use it to treat water by using 16 drops of regular household liquid bleach per gallon of water. Do not use scented, color safe or bleaches with added cleaners.
  • A large plastic tub and pitcher
  • Flashlights in several places and certainly on each floor in a house. Hand-cranked flashlights don't use batteries and are an option. Best to have both types on hand.
  • Battery-run radio with earphones, and/or small speakers
  • Extra batteries for flashlights and radio (the batteries last longer if kept in the fridge when there is no power outage)
  • Extra blankets and perhaps sleeping bags for warmth
  • If at all possible, invest in a fleece blanket
  • First Aid kit, same as in your automobile
  • Hand warmers which when snapped, they heat up. In an emergency, they can act as a heating pad
  • Roll of duct tape
  • Plastic sheeting for making a shelter
  • Scissors
  • Flameless candles are now battery run with small LED lights
  • Garbage bags and ties for sanitation needs
  • A box of moist towelettes (these tend to dry out so keep current)

Medical Supplies:

  • Compile all the medicines you take plus any over the counter items in one place such as a small bag. Stay on top of refills so you don't run out of an important medication
  • If children are involved, you will need their medications as well
  • Items duplicated from the automobile first aid kit
  • Services, devices, tools and techniques you use to live with a disability
  • Medical needs such as canes, crutches and walkers should have a name tag on them with identification
  • Extra eyeglasses and/or hearing aids
  • Medical alert tags (that you are supposed to be wearing)
  • A written list of your medications and description of your illness so if you are unable to speak in an emergency, the information is available. This can be kept in your wallet or purse. This is in addition to the same information in your Emergency Grab Bag
  • If you use a motorized wheelchair, have a light weight manual chair available for emergencies. Know the size and weight of your wheelchair, in addition to whether or not it is collapsible, in case it has to be transported
  • Personal hygiene products and feminine supplies
  • Deodorant
  • Toothbrush, toothpaste and mouth wash
  • Baby's diapers and baby wipes
  • Baby powder—not just for babies. If your hair gets oily, dust a bit of powder on your scalp and brush through. It absorbs oil
  • Cotton balls or cotton pads

General Supplies:

  • Find out if you can subscribe to your town's emergency alert system. If so, list your cell phone number (provided it is charged and on) which means you'd get the alerts even if you are not home. Keep in mind cordless phones need electricity and only work with them plugged in. No electricity, no phone. It is a good idea to have at least one telephone that is wired
  • Keep basic tools handy such as wrench, screwdriver and hammer handy in case of needing them to turn off water or gas lines, or building some sort of tenting.
  • Create and keep posted a hardcopy (print off from computer, if that's where you keep information) of important contact information
  • Keep handy a paper map of your local area. If everything is on your smart phone, computer or electrical device, and there is no power, then what?
  • When severe weather or a snowstorm is forecast during the winter, have extra blankets at the ready, especially if outages are frequent. Invest in a simple zip-up sleeping bag that can handle low temp if blankets are not enough to keep you warm
  • Invest in a set of thermal underwear-purchasing these items at the end of a selling season, often when they are greatly discounted, will save you money
  • Keep a pad of paper, pen and pencil handy
  • If you receive any governmental funds by mail, such as social security disability checks, consider arranging for direct deposit so as not to interrupt receipt of money. In a disaster or heavy snowstorm, mail can be delayed or stopped. Register for direct deposit at: www.GoDirect.org. You can also call your Social Security office to make arrangements
  • For those who may not have a bank account, you can sign up for The Direct Express® prepaid debit card as a safe and easy alternative to paper checks. Call toll-free at (877) 212-9991 (phone), (866) 569-0447(TTY) or sign up online at: www.USDirectExpress.com
  • If you depend on well water and a storm is forecast, fill your bathtub with water, along with several jugs of water—not for drinking, but to flush toilets
  • If you have a baby or small child, make sure you have enough diapers, formula and supplies for them
  • Try to keep some cash on hand in small bills ($10.00 or $20.00). In a power outage, the ATM's do not work. Put the money in an envelope and mark it "for emergency use only" and put it with important papers or your emergency grab bag
  • If possible, keep a couple of small battery operated fans on hand. Purchase them on sale at the end of the summer selling season. If the electricity goes out in the summer, they could be a life saver
  • Winter cleats such as Yaktrax that slip over your shoes or boots and keep you from slipping on ice. Such items can be found on the shopping channels, in the Walmart automotive section and possibly at Sears. This is a seasonal item so you will only find it in the winter selling season.

For folks whose lose power and have gas hot water heater and/or stove, it may be possible to light the pilot light on the hot water heater using a long handle butane lighter. Check with your manufacturer or a plumber. To light a gas stove pilot light, use the same type of lighter, turn on the gas slowly and light the pilot light on the stove. Do not put your face down into the stove to watch!

Snowstorms and hurricanes are common to our area. However, 2011 showed us we also have to be aware of tornadoes and earthquakes—2011 saw it all. Should the household have to be evacuated, for whatever reason, there are a few precautions CFS/FM patients, or any chronically ill person, should take. Since a timeline is not known for returning, the reasoning is better to be prepared and not need something, than need it and not be prepared.


In case of evacuation take-with items:

  • Emergency Grab Bag of Documentation
  • All your medicines in their bottles. Keeping them together in one spot helps the grab and go. For those who put out the medication in a weekly container, grab that container, but also take your bottles
  • Computer and cables, flash drives of information
  • Battery chargers for phone, computer, cameras, and if applicable medical devices which require batteries such as wheelchairs, hearing aids, etc.
  • A complete change of clothing, extra tops for layering, underwear, long pants and socks and sturdy shoes
  • If during the winter, take a warm coat, gloves, hat and scarves
  • If in summer, take battery operated small fans
  • Specific pillows, if needed
  • Any medical devices that are used—i.e. cane, wheelchair
  • Pets—if you have a pet, you will need to bring some food, snacks, leash, coat, medication if needed, etc., plus your pet. Your pet's medical information should be in your Emergency Grab Bag of Documentation kit
  • If you have children and time allows, take some books, toys, crayons, paper, puzzles and games to keep the children entertained, as well as their favorite stuffed animal
  • If you are in a shelter that has electricity, computer games or videos may be an option
  • If you live alone, make a plan with support folks and/or friends and make sure someone you trust has an extra key to your place. Put their name and number in your Emergency Grab Bag of Documentation kit as a contact
  • If you are a woman, then you know to grab your pocketbook, checkbook with checks and wallet
  • Heating pad, if necessary along with an extension cord assuming there is electricity where you are going
  • Any special foods you'll need
  • Cash
  • Identification such as a driver's license, medical insurance card, social security card, etc.

Although this looks like a long list, do a little at a time, and before you know it, it will be done. Start with the Emergency Grab Bag of Documentation, as that is probably the most important, next to your medications.

Summary of the Massachusetts CFIDS/ME & FM Association Fall 2011 Educational Forum

The Massachusetts CFIDS/ME & FM Association held its Fall 2011 educational forum, co-sponsored by the Massachusetts Department of Health, on November 5, 2011 at the UMass-Hinton State Laboratory Institute Auditorium in Jamaica Plain, MA.

The meeting was a review of research and other content from the September 2011 International Association for Chronic Fatigue Syndrome /Myalgic Encephalomyelitis (IACFS/ME) Conference held in Ottawa, Canada. The written summary is in two parts.

Part 1: Dr. Anthony Komaroff’s review of the conference highlights (presented at the meeting on audio, with accompanying slides)

Part 2: Dr. Kenneth Friedman and Dr. Alan Gurwitt spoke about other studies, news and developments.

MassCFIDS 2011 Fall Meeting Highlights Part 1: Dr. Komaroff's Summary of IACFS/ME 2011 Meeting

The Massachusetts CFIDS/ME & FM Association held its Fall 2011 educational forum, co-sponsored by the Massachusetts Department of Health, on November 5, 2011 at the UMass-Hinton State Laboratory Institute Auditorium in Jamaica Plain, MA. Review of research abstracts from the September 2011 International Association for Chronic Fatigue Syndrome /Myalgic Encephalomyelitis (IACFS/ME) Conference held in Ottawa, Canada was presented in two segments: Dr. Anthony Komaroff’s review of the conference highlights (on audio, with accompanying slides), while Dr. Kenneth Friedman and Dr. Alan Gurwitt spoke about other studies, news and developments (their presentation will be released as a separate article, due to the length and depth of content).

As always, Dr. Komaroff’s summary of the IACFS/ME meeting highlights was most informative and articulate, and the Massachusetts CFIDS/ME & FM Association is deeply appreciative of Dr. Komaroff’s continued interest and support of our educational programs in giving us permission to replay this material.

The following article reviews studies selected by Dr. Komaroff which he felt had represented some of the more intriguing and provocative areas of research, as listed:

Epidemiology
Virology
Immunology
Exercise challenge studies
Studies of the brain
Gene structure and expression
CFS multi-center research initiatives


Epidemiology

Long-term ME/CFS

A long-term study done by Dr. Leonard Jason, from DePaul University in Chicago IL, helps to answer the question of what is the longer term history of CFS. Data gathered for 213 patients, over a period of 15 years or longer, showed that 67% of individuals continued to fit CFS criteria; some who initially had idiopathic chronic fatigue, went on to develop full-blown CFS; and half of those who no longer had CFS, still had fatigue. Dr. Komaroff explained this suggests there is a continuum between full-blown CFS, idiopathic chronic fatigue, and normal health. Thus over time, some patients move back and forth between these categories. This study confirms that CFS is a chronic illness and in adults, it can persist for decades.

Understanding of ME/CFS by the medical community and the public

Two studies conducted by Dr. Elizabeth Unger, from the Centers for Disease Control and Prevention (CDC), show improvement in the overall recognition of CFS by the medical community and general public over the past 20 years. The first study focused on health care practitioners. Of the 2,000 surveyed, the majority of them (94%) had heard of CFS; 37% reported they had personally diagnosed cases of CFS in their practice; and about 14% of them still thought CFS was a psychiatric condition.

The second study surveyed 4,200 U.S. citizens. More than of half (57%) reported they had heard of CFS, while only 2% of the public still believed it was a psychiatric condition. Dr. Komaroff said that when thinking back to the first international CFS conference held in 1992, this data demonstrates substantial change in awareness and knowledge of CFS.


Virology

Enteroviruses 

One of the poster presentations made by Dr. John Chia and his son, Andrew Chia, demonstrated that enteroviral infections were frequently found in CFS. Their research confirmed enteroviruses (EV) in the tissue samples taken from 132 consecutive stomach biopsies of CFS patients. (Some of these patients also had gastrointestinal symptoms). The majority of CFS cases tested positive— 82% had viral protein and 64% had viral nucleic acid, while EV was found in only a small fraction of controls (i.e., 10% or 4 of 40 controls).

In addition, when biopsied material that looked like it contained viral antigens and proteins was injected into animals which were later checked for replicating virus, many of them revealed production of antiviral proteins and antibodies to the EV. The importance of this study, according to Dr. Komaroff, was that the Chias’ research suggests EV may play a central role in this illness.

XMRV and pMLV false-positive results came from contamination

Topics of utmost interest at the Ottawa conference were xenotropic murine leukemia retroviruses (XMRV) and polytropic murine leukemia viruses (pMLVs), especially since the results of the multi-laboratory XMRV/MLV study were being published by Science at the same time. Dr. Komaroff briefly touched on the differences in research findings, from the original data published by Whittemore Peterson Institute (WPI) to the final results of the Blood Working Group Study.

Two years ago, WPI came out with some remarkable information: a significant percentage of CFS patients were found to have viral nucleic acid and viral antigen to XMRV; that the virus could be cultivated from patients’ plasma and cells; that antibodies to the virus were found in CFS patients; and moreover, that some of the healthy blood donors had also tested positive.

A second study by scientists from the National Institutes of Health (NIH) and Food and Drug Administration (FDA) only looked for XMRV viral nucleic acid, which they failed to confirm. However, they detected MLV-related virus in CFS. Many laboratories around the world tried to repeat the studies, but results came back negative and/or with inconsistencies. A large replication study was established to verify these findings. The research was spread across 9 highly reputable laboratories that conducted blinded testing of blood samples from a large CFS patient group, including those which had previously tested positive for XMRV or pMLVs. But the results were negative.

False positives of XMRV /pMLVs are now attributed to contamination of laboratory reagents and commercial reagents with mouse DNA. Dr. Komaroff indicated that XMRV was an accidental laboratory recombinant virus, going back to the early 1990s and considered this finding in itself as troubling, because quite a few people developed CFS many years prior to this incident.

Various cell lines were also found to be contaminated with mouse DNA and this contamination is considered to be widespread, affecting many laboratories around the world. In view of these results and developments, Dr. Komaroff regards XMRV/ pMLVS research to be on very “shaky grounds.” 


Immunology

NK-cell function in ME/CFS—conflicting results?

Most previous studies on Natural Killer (NK) cell function had shown reduced function in CFS patients. However, two studies presented at the Ottawa conference came to two different conclusions. One study confirmed impaired NK cell function in CFS/ME patients which may be related to alterations in cytokines and reduced immune function in patients with CFS (EW Brenu). The other study found that NK cell function was higher in patients while they were acutely ill and during a period of time following the active infection (B Katz).

Dr. Komaroff thought this was quite feasible because if a viral infection is believed to trigger this illness, which applies to many but not all cases, then NK cell function could increase during the initial phase of infection and remain relatively stable, for a while, immediately after an infection. But when patients become chronically ill and NK cells are repeatedly activated to protect the body against viruses and other pathogens, this could lead to an exhaustion of NK cell function response (i.e., what is commonly seen in full-blown, persistent CFS).


Exercise challenge studies

An exercise challenge study is actually a set of maximum exercise tests (i.e., in this case, not an elaborate technique, but a commonly used test in clinical settings for decades) that is conducted 24 hours apart and can measure post-exertional malaise. Dr. Komaroff regards work done by Betsy Keller in this field to be provocative and valuable because it is able to demonstrate significant changes between the first and second exercise tests, such as decreased work capacity, decreased heart rate, lower anaerobic threshold and lower functional capacity. After the second test, post-exertional malaise brought significantly reduced functional capacity—below that which would be typically needed for many sedentary jobs and daily living activities. Exercise challenge tests, in Dr. Komaroff’s opinion, suggest a way that post-exertional malaise could be documented for a variety of needs.


Studies of the brain

Dr. Komaroff remarked that many interesting studies of the brain were presented at the conference, even though he did not go into too much detail on these. Some of the many brain abnormalities included reductions in grey matter and white matter (IH Treasaden) and decreased activation of basal ganglia (i.e., typically in the caudate and globus pallidus) in CFS and other fatiguing, neurological illnesses using advanced functional magnetic resonance (fMRI) techniques (AH Miller).

Other remarkable research alluded to by Dr. Miller (not part of the abstracts presented at the conference) was the ability to experimentally induce fatigue and reduce activation in basal ganglia, in humans, with the infusion of pro-inflammatory cytokines. Symptoms of CFS have long been associated with pro-inflammatory cytokines produced in, or getting through the brain blood-barrier, and into the central nervous system.

Another study of the brain assessed blood flow in patients with CFS, those with major depressive disorder, and healthy controls. Cerebral blood flow to certain regions of the brain was notably reduced in CFS when compared to healthy controls and no significant differences were found in values between CFS and major depressive disorder (JP Dyke).

Though this pilot study was felt to be intriguing, Dr. Komaroff said it needs to be reproduced, because a small study like this is prone to the beta error problem (i.e., the problem in finding real differences in small studies is difficult). The measurement of tissue blood flow in the brain has greatly advanced, and this technology is now widely available and may allow for better assessment and treatment of patients. But how this technology will be ultimately used needs to be worked out.


Gene structure and expression

Do people with CFS have differences in the way their genes are built—from inheritance— compared to health controls? Is there a difference in which genes are “turned on” (expressed)? Is there a relationship between these differences and the underlying biology of this illness?

Dr. Komaroff reviewed a selection of genomic and genetic research presentations from the Ottawa conference which exemplify how this science and tools can help to identify patterns unique to CFS.  It is important to note many other fields are using gene expression patterns/results in their studies to evaluate CFS compared to healthy controls or other illnesses.

Gene structure

Gene structure in CFS was assessed by Dr. M.S. Rajeevan, with the CDC, by using community-based samples and comparing these to healthy controls. This study reported polymorphisms in genes that are involved in the immune response—more specifically, complement cascade, chemokine production and toll-like receptor signaling—which were different in CFS patients. Basically, this study demonstrates how changes in gene sequences detected could determine that these genes played a role in innate immune response.

Dr. Lea Steele, at Baylor University, combined an epidemiological study with molecular biology, and identified two polymorphisms that reduced the body’s ability to degrade nerve gases and pesticides, respectively. These polymorphisms were found to correlate strongly with the presence of Gulf War Syndrome in individuals who had been military personnel exposed to those environmental toxins, and not in those unexposed. Steele’s study also showed a dose-response relationship with homozygotes of these polymorphisms had a clearer, more severe form of GWS compared to heterozygotes (per Dr. Komaroff’s IACFS/ME Meeting Highlights PowerPoint slides on Gene Structure). Dr. Komaroff remarked that it remains to be seen whether these results in GWS will have any relevance to CFS/ME or Fibromyalgia.

Gene expression

A mini primer on gene expression, prepared by Dr. Komaroff, was helpful in getting across the basic aspects of this science, in this way:

Genes are only important if they are “expressed”, or “turned on” and are making messenger RNA.  The central process can be stated as follows:

DNA→ makes messenger-RNA (mRNA)→ makes Protein.

DNA not only makes full-length genes but also makes tiny microRNAs, which feed back on specific mRNAS and interfere with protein production. Consequently, they block protein production—the result is they “turn off” the gene.

A method of detecting gene expression is using a tool called microarrays, which allow for extensive analysis of many genes at one time (up to 22,000). This technique makes it possible to take a tissue and be able to tell which genes are turned on and off. Microarray tests are performed on silicone chips, and when a gene sequence finds its complementary match on the chip (when there is a fit), they will light up—the patterns of genes that are “turned on” help to make many inferences about what is going on.

Gene Expression studies

The importance of gene expression can be demonstrated in this preliminary study that had found 6 miRNAs to be substantially down-regulated in both NK-cells and CD8+ cells in CFS patients, compared to healthy controls. These cells play a critical role in antiviral activities and have been shown to function defectively in CFS in previous studies. These miRNAs regulate the expression of genes involved in cell cycle regulation, apoptosis, and toll-like receptor expression (EW Brenu).

An exercise challenge test, conducted at University of Miami, confirmed an enhanced alteration in the expression patterns of a group of genes, as previously found in ME/CFS by Dr. John Kerr from the U.K. (i.e, the Miami study used the Kerr ME/CFS platform to evaluate gene expressions). The genes that were altered are those which play important roles in antiviral defense, mitochondrial function, and immune activation. The same changes were not seen in healthy controls or patients with Gulf War Illness. (L Garcia)

Dr. G. Broderick used data from Dr. Katz’s study of adolescents with infectious mononucleosis and post-mono CFS, and his study could identify biological pathways that are up-regulated or down-regulated. Children with post-mono CFS had 5 signaling pathways with altered activity, most notably, the phenylalanine metabolic pathway which was down-regulated. Patients with greater down-regulation had greater fatigue—a “dose-response” relationship (Broderick, Katz, Taylor).

Dr. Lucinda Bateman presented research done by Dr. Alan Light and Dr. Kathleen Light that looked for changes that exercise would make in gene expressions, in patients with CFS, CFS and Fibromyalgia (FM), FM only, Multiple Sclerosis (MS), and in healthy controls. (CFS and FM patients used in this study were referred by Dr. Bateman, clinical collaborator.)

Dr. Bateman reported that both patient self-rated and physician-rated symptom severity correlated with greater post-exercise increases in these genes. However, a subgroup (about 30%) of patients did not demonstrate such gene expression changes and the clinical clue for difference was the history of orthostatic intolerance in this subgroup. Results seen in CFS patients were not seen in healthy controls, FM only, or MS.


CFS multi-center research initiatives

The good news is there is a movement by key federal health agencies and other facilities/organizations, to better coordinate and collaborate research efforts, as shown below:

  • CFIDS Association clinical and laboratory database
  • NIH-funded multi-center study, centered at Columbia University
  • CASA—Initiative of the NIH and CDC to develop common instruments and strategies for multicenter CFS research studies
  • Chronic Fatigue Initiative—Multicenter initiative to discover possible pathogens and mechanisms of disease

Notice about names

The Massachusetts ME/CFS & FM Association would like to clarify the use of the various acronyms for Chronic Fatigue Syndrome (CFS), Chronic Fatigue & Immune Dysfunction Syndrome (CFIDS) and  Myalgic Encephalomyelitis (ME) on this site. When we generate our own articles on the illness, we will refer to it as ME/CFS, the term now generally used in the United States. When we are reporting on someone else’s report, we will use the term they use. The National Institutes of Health (NIH) and other federal agencies, including the CDC, are currently using ME/CFS. 

Massachusetts ME/CFS & FM Association changed its name in July, 2018, to reflect this consensus.
