ANTIBIOTICS FOR PATIENTS WITH ME/CFS?

RETROSPECTIVE ANALYSIS OF A COHORT OF INTERNATIONALLY CASE DEFINED CHRONIC FATIGUE SYNDROME PATIENTS IN A LYME ENDEMIC AREA

Samuel Shor¹, MD, FACP

ABSTRACT

Background

Chronic fatigue syndrome is a diagnosis of exclusion for which there are no markers. Lyme disease is the most common vector borne illness in the United States for which chronic fatigue is a frequent clinical manifestation. Intervention of patients with Lyme disease with appropriately directed antimicrobials has been associated with improved outcomes.

Methods

An arbitrary date was chosen such that all patients registered in the database of the practice of the PI, which is located in the Lyme endemic area of Northern Virginia area were reviewed. The diagnosis of clinically significant fatigue > 6 months was chosen. Inclusion criteria required fulfilling the International Case Definition for CFS.

Results

Of the total 210 included in the analysis, 209 or 99% were felt to represent a high likelihood of “seronegative Lyme disease.” Initiating various antimicrobial regimen, involved at least a 50% improvement in clinical status in 130 or 62%. Although not achieving the 50% threshold according to the criteria discussed, another 55 patients subjectively identified a beneficial clinical response to antimicrobials, representing a total of 188 or 88% of the total identified as having a high potential for seronegative Lyme disease.

Conclusions

A potentially substantial proportion of patients with what would otherwise be consistent with internationally case defined CFS in a Lyme endemic environment actually have a perpetuation of their symptoms driven by a persistent infection by Borrelia burgdorferi. By treating this cohort with appropriately directed antimicrobials, we have the ability to improve outcomes.

Of course here in the UK a growing number of areas are being found to have ticks carrying Lyme Disease so depending on having been infected in just the known Lyme Endemic areas is just not the best way forward. What we need is much more research relevant to the situation in the UK.

Meanwhile anyone with ME/CFS symptoms should at least consider the possibility that it could be Lyme Disease, not everyone is aware of the sometimes poppy seed sized tick that can infect us and currently research shows that blood tests can miss up to 50% of cases, with about 50% of those infected not seeing a typical Bulls eye rash.

Lyme Life written in 2009

I started suffering with arthritis in mainly my large joints especially my knees 6 years ago. The symptoms varied and I remember saying that every joint was affected except my elbows to one doctor. I was told it would be hormonal and to take the usual supplements cod liver oil or glucosamine ( I would certainly recommend buying shares in the companies producing these supplements) They had no noticeable affect.

All my symptoms deteriorated significantly over a few weeks,4 years ago. Hips shoulders and knees being the worst and I started with muscle weakness in upper arms and upper legs. I had difficulty standing and walking across a room. I was unable to walk upstairs and my husband was making plans to convert to a downstairs bedroom. I had seen 5 doctors and 3 Rheumatologists and put on steroids for Poly Myalgia Rheumatica diagnosis. I had been diagnosed with Fibromyalgia and ME/CFS.

I have X rays and scans showing signs of osteoarthritis and Rheumatoid arthritis. ( later note.- the X rays done some years into treatment showed my hands completely normal no signs of inflammation or RA confirming how they felt - normal) I have been retired early from the Civil Service having lost my job not to mention my earning potential. My illness seemed to progress through my body not affecting the same joints left to right at the same time. I had bursitis in left hip, right hip, left elbow. I had synovial thickening in both wrists. At that time I could not lift and hold a magazine so lifting a kettle I could only do if a third full and with two hands. Each joint in my hands fingers feet and toes were affected. I had swallowing difficulties and many other symptoms. None of this describes the endless and awful pain whenever I moved or the tiredness but inability to get quality sleep.

Two years ago my GP gave me Amoxicilin for a sinus/throat/chest infection. All my arthritis symptoms improved. The course ended the symptoms deteriorated I started a second course the symptoms improved. The improvement was more significant than when I had started taking steroids. This led my GP to suspect Lyme Disease. I laughed because we do not travel abroad but she said they had had other cases in the surgery in the early stages of tick bite and Erythma Migrans rash. She said but you have not had a bite. I said oh yes I have I had two on my ankles with rashes, March 05 this was confirmed on her computer when I had seen a locum doctor. My worst symptoms were waking up feeling rigid and having to painfully flex every joint in my body before struggling to get up. The only other time I had experienced this was in May 2003 during a flu like illness like no other I had ever experienced. At that time I had a bite and similar rash on my right foot which lasted like the other rashes about four weeks. I had also consulted the surgery and it was dismissed as a virus. I walked our dog daily in the woods adjacent to our house where the deer roam, prime tick area. Thus started my very lengthy search about Lyme Disease leading me through Lyme Disease Action to a doctor who specialises in this illness. He confirmed my GP's suspicions. I never had a positive blood test but then they are antigen tests and there is much research that shows they are unreliable. In my case the year of steroids and many weeks antibiotics could have affected the results. So with a clinical diagnosis and following ILADS International Lyme and Associated Disease Society guidelines I continued on antibiotics for two years. Both my doctors continued to treat me despite of Health Protection Agency advising against long term antibiotics. I am now nearly 100% recovered I have no pain or muscle weakness. I can walk upstairs something I could not do for three and a half years. I can garden do house work and live a normal life. I still need to pace myself and with only a few months to 60 will not be looking to return to work. Life is such a joy. Sadly there is much controversy about Lyme Disease and doctors in UK are taught that it is so rare. Well where I live in Guildford I have been in contact with a dozen other people with it so perhaps not so rare as HPA would like us to believe. I am in touch with nearly 2000 other patients through a chat line Eurolyme most had been misdiagnosed with several other illnesses. Look at UK charity Lyme Disease Action if you want to read more about this illness. There are many MP's taking an interest in the problems surrounding diagnosis and treatment see above charity links into a recent meeting at the House of Commons.

Thank goodness there are some thinking doctors around who have courageously treated me against opposition and I have made such a miraculous recovery albeit rather a lengthy one. One day there will be many more people who are helped with their chronic illnesses when IDSA starts taking note of what our courageous LLMD’s are doing following ILADS Guidelines.

ME/CFS, Fibromyalgia, Poly Myalgia Rheumatica, Arthritis, Bell’s Palsy, MS,MN, ALS, Parkinson’s, Alzheimer’s, Heart Block, Stroke, Psychiatric, gastric problems the list is endless. Not all suffering from Lyme Borrelia but how many are even properly assessed for it.
