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.

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.

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.


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.

I have been remiss in posting recently ( busy enjoying life ) and also finding lots of interesting info on Lyme Disease and ME/CFS through Facebook but I had to post the above excellent research.

The above study concentrated on a known endemic area but here in the UK there is not so much research done on Lyme Disease areas to see where it is endemic.

My own diagnosis was part of a domino affect.

A nurse training at the Royal Surrey hospital had a patient admitted, on the ward with a tick bite and overheard talk about Lyme Disease.

Never having heard of Lyme Disease she looked it up on the Internet.

Only a fortnight later her new found knowledge proved useful when her husband had a tick attached whilst sitting in his garden. The husband attended the local surgery and Lyme Disease was dismissed as unlikely as the patient had not been infected in a known Lyme endemic area.

However a few days later the typical bulls eye rash appeared (lucky him as 40% of cases often don't get a rash). Still his GP and Dermatologist shook their heads and dismissed Lyme Disease, however the wife had by then pursuaded the GP to prescribe antibiotics and just as well as the NHS blood tests came back positive for Lyme.

That was the first known case at my surgery, later other cases presented in the early stages of tick bite and bulls eye rashes and eventually led to my GP suspecting I had Lyme when a chance course of antibiotics significantly improved my chronic arthritis and muscle weakness (My story is in the right hand column).

Since, there have been several patients present at my surgery and several other surgeries in the Guildford locality- seems once doctors start to look they find.

An area is only endemic when sufficient research has been done to establish that it is endemic - if the research is not done that does not mean there is no Lyme Disease in the area.
