COULD BORRELIA MIYAMOTOI INFECTIONS EXPLAIN PERSISTENT SYMPTOMS IN LYME DISEASE PATIENTS?
“This is the first study to investigate the presence of B. miyamotoi antibodies in a clinical population experiencing persistent symptoms and suspected tick-borne illness,” writes Delaney and colleagues from Columbia University Irving Medical Center. [1] According to the findings, Lyme disease patients testing positive for Borrelia miyamotoi were more likely to present with sleepiness and pain.
Borrelia miyamotoi (BM) is another tick-borne pathogen and “unlike Lyme disease, erythema migrans rash, and arthralgias are uncommon,” the authors write in the journal Frontiers in Medicine. The infection is diagnosed with polymerase chain reaction (PCR) called glycerophosphodiester phosphodiesterase (GlpQ) enzyme immunoassay.
Investigators looked at the incidence of BM in 82 patients who were seeking a second opinion regarding persistent symptoms which included fatigue, pain, neurocognitive, and psychiatric problems.
In their study, 1 out of 4 Lyme disease patients tested positive for Borrelia miyamotoi,using a GlpQ test. The BM positive group were significantly more likely to suffer from sleepiness (according to the Epworth Sleepiness Scale) and from pain, as measured by the McGill VAS Pain Scale, and Zung Anxiety Scale.
Eight patients with Lyme disease and Borrelia miyamotoi were hospitalized. “Eight of 21 (38%) reported hospitalization (seven medical and one psychiatric) since symptom onset, three for cardiac and two for neurologic abnormalities,” according to the authors.
All of the patients, except for one, with Lyme disease (LD) and Borrelia miyamotoi were treated with antibiotics. “All 21 received prior antibiotic treatment, of whom 20 received at least 2 weeks of doxycycline or amoxicillin.”
Five of the 21 patients with LD and BM lived outside of the with Northeast/Mid-Atlantic states. “Two lived in California, two lived in Florida, and one lived in Illinois.”
Study insights
The study found that clinicians are not testing for Borrelia miyamotoi, as only 1 out of the 82 study participants were tested for the infection.
Furthermore, clinicians were often dismissive of a tick-borne illness. “Many patients reported that their clinicians dismissed the possibility of tick-borne illness both at the onset and during the course of their illness and attributed symptoms to psychological stress,” writes Delaney.
The authors raise a public health concern:
“In Lyme disease, delayed diagnosis and treatment is associated with prolonged symptoms. The same may prove true for B. miyamotoi disease.”
Editor’s note: A co-infection with Borrelia miyamotoi may explain why some Lyme disease patients are sicker than others. Unfortunately, there are still problems with the reliability of testing for Borrelia miyamotoi. There is also uncertainty over the best treatment approach for the infection.

Re: Tick bite
Dear Editor
Razai et al, in their consultation on tick bite, missed an important message to learners (1).
The most common infectious agents transmitted by Ixodes species ticks in North America that have the potential for co-infection with B burgdorferi are Anaplasma phagocytophilum, Babesia species, deer tick (Powassan) virus, Borrelia miyamotoi, and the Ehrlichia muris–like agent (2).
A phagocytophilum is transmitted by the same Ixodes ticks as B burgdorferi in the United States and causes fever, chills, headache, myalgia, and fatigue arising 1 to 3 weeks following tick exposure. Most cases are mild and self-limited. However, severe manifestations may include respiratory failure, adult respiratory distress syndrome, peripheral neuropathy, rhabdomyolysis, acute renal failure, pancreatitis, and coagulopathies.
It has been found that in Wisconsin, approximately 3% of I scapularis ticks examined were co-infected with B burgdorferi and A phagocytophilum (3). A similar study in 11,000 ticks in public parks of New York State’s Hudson Valley Region found that co-infection rates of nymphs and adults were 0.5% and 6.3%, respectively (4).
The frequency of humans with Lyme disease simultaneously co-infected with A phagocytophilum from various studies ranges from 2% to 10% (5,6). Similirly, Babesiosis is transmitted through the bite of infected I scapularis and I pacificus ticks. Most patients are asymptomatic or have mild, self-limited disease but may be complicated by renal failure, acute respiratory distress, and shock.
In a study of patients with Lyme disease from southern New England, approximately 10% were co-infected with babesiosis (7).
Unlike Lyme disease and Anaplasmosis, doxycycline is not an effective treatment of babesiosis and requires atovaquone and azithromycin or combination of clindamycin with quinine, making it imperitive to consider this diagnosis in mind in patients with tick bite.
Of the 3 species of Ehrlichia in United States, only E muris–like (EML) agent is transmitted by I scapularis is the vector of this emerging pathogen(8).
Possible co-infections should be considered in any patients who are diagnosed with tick bite or Lyme disease, especially those who have unexplained leukopenia, thrombocytopenia, or anemia, or who fail to respond to treatment for Lyme’s disease.

**Comment**
This important letter to the editor highlights many contentious issues Lyme/MSIDS patients have to muddle through. From where I sit, I disagree with the author’s statements that these infections are ‘mild and self-limited’, but I deal with sick people – not healthy. If there’s one thing I DO know, it’s that these infections have been downplayed for far too long, and it’s been a real problem. Patients haven’t been taken seriously for over 40 years!
The consideration of coinfections; unfortunately, is not common in mainstream medicine regarding Lyme/MSIDS. They still treat this as a one germ disease with doxycycline curing it, when nothing could be further from the truth: https://madisonarealymesupportgroup.com/2018/10/30/study-shows-lyme-msids-patients-infected-with-many-pathogens-and-explains-why-we-are-so-sick/
