Have you had
Lyme disease (LD) and received 4 weeks of treatment?
If so, should
you later experience symptoms that could be Lyme-related without
the possibility of becoming re-infected, do not worry, the antibiotics
almost certainly eradicated the LD bacteria from your body, regardless
of how long you were infected before treatment.
The symptoms
you're experiencing are because you are getting old. You just
think they're Lyme symptoms because you've heard previous reports,
riddled with hyperbole, that detail a wide array of physical
and mental impairments you can get from the disease.
Of course,
in some cases it is possible an ailment is responsible for the
symptoms you're experiencing. If so, what you need is another
diagnosis to find the actual cause of your symptoms. After all,
you only had LD.
Convinced?
Hopefully
not, but a recent study hailed as one of the few studies that
examine "the long-term health of patients diagnosed with
Lyme" deceptively concludes that long-term mental or physical
abnormalities in Lyme patients are uncommon.
"Long-term
Outcomes of Persons with Lyme Disease," published in a February
edition of the Journal of the American Medical Association (JAMA)
concludes that people who receive conventional therapy for LD
return to just as good health as people who never had the disease.
The study observed 678 patients for up to 11 years and focuses
on cases reported to the Connecticut Department of Health from
1984-91.
While 69%
of the patients reported an increase frequency of joint pain,
fatigue and headaches, most patients, the study says, attributed
the symptoms to aging or other illness such as a stroke. According
to the study, the frequency of symptoms was similar to that of
a control group of people not diagnosed with the disease.
- The study,
however, has a number of flaws that make it hard to accept its
conclusions:
1) It examines
mainly patients with early LD. Roughly 88% of the patients who
met the Centers for Disease Control and Prevention's (CDC) narrow
surveillance criteria had the classic, telltale, bull's eye Lyme
rash or multiple Lyme rashes. Therefore, it is likely these patients
received timely diagnosis and antibiotic treatment. No patients
in the study exhibited late-stage symptoms such as encephalopathy
(any dysfunction of the brain) or encephalomyelitis (acute inflammation
of the brain or spinal cord). These are the patients most prone
to treatment failures and long-term health problems from LD.
2) The data
was collected not by a trained health professional but by a research
assistant asking questions over the phone using a symptom history
questionnaire that has no established reliability or validity.
No patients underwent physical examination.
3) Although
the majority of patients felt they were cured of LD at follow-up,
25% of the patients who met the LD surveillance criteria and
37% of those who did not were still uncertain whether or not
they still had the disease.
4) Contrary
to the conclusion by one of the study's authors, Eugene D. Shapiro,
MD, the study DID NOT find persons who have had Lyme to be just
as mentally and physically healthy as persons without Lyme. A
212 person subset from the 678 patients, matched against 212
healthy controls, revealed Lyme patients had an increased incidence
of joint or muscle pain (33.5% to 24.1%), fatigue (19.3% to 14.6%),
and ability to formulate ideas (11.3% to 3.8%). The study also
found patients experienced increased difficulty with memory,
exercise, naming objects, and judgment.
A recent study
published in the LDF's Journal of Spirochetal and Tick-Borne
Diseases (JSTD) examines a patient group largely ignored by many
researchers and clinicians: patients with chronic LD that experience
cognitive deficits despite receiving 4-16 weeks of intravenous
antibiotic therapy.
That study,
conducted by LDF scientific adviser Brian Fallon, found repeated
antibiotic therapy can be beneficial among patients who have
been previously treated, and even with patients who tested negative
on Western blot. Patients treated intravenously showed the most
functional and cognitive improvement.
