Can Lyme disease trigger an autoimmune disease?

An increasing number of studies indicate that Lyme disease may ignite an autoimmune reaction in some individuals or symptoms may mimic an autoimmune disease. In their report, "Lyme arthritis presenting as adult-onset Still's disease," researchers describe the first known case of Lyme disease triggering Adult-Onset Still's Disease, an auto-inflammatory condition that can impact the entire body (systemic disease).

 

Adult-onset Still’s disease (AOSD) is often thought to be an autoimmune disease, but is, in fact, a systemic auto-inflammatory condition, believed to be caused by an over-reactive immune response to an infection, such as Lyme disease. As Cimmino points out, both diseases share several clinical characteristics.¹

Still’s disease can cause “a triad of high fever, salmon-colored nodular rash and arthritis and/or arthralgia,” explains Ocon in the British Medical Journal.² Lyme disease can also present with fevers, atypical rashes and arthritis and/or arthralgias.

Both conditions were first identified in children. Still’s disease was initially considered a severe version of juvenile idiopathic arthritis (JIA), while Lyme disease symptoms were originally attributed to juvenile rheumatoid arthritis (JRA).

Lyme disease and autoimmune diseases

A growing number of studies indicate that Lyme disease may trigger an autoimmune response in some individuals or symptoms may mimic an autoimmune disease.

Cross et al. describe the case of a Lyme disease patient with persistent neuropsychiatric symptoms who developed an autoimmune disorder, known as Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS).³ The patient recovered following treatment with intravenous immunoglobulin (IVIG).

Investigators report the case of an elderly woman whose Lyme disease symptoms mimicked dermatomyositis (DM), a serious autoimmune disease which typically requires immunosuppressive therapy. The patient was eventually diagnosed with Lyme disease and recovered completely with antibiotic treatment.

The authors suggest, “[Lyme disease] could be a great mimicker of other autoimmune diseases like DM.”

Case Presentation: Still’s disease

A 61-year-old man presented with a “complaint of intermittent spiking fevers, night sweats, generalised malaise, as well as a history of erythematous circular rashes on his right upper extremity,” writes Ocon.²

He was diagnosed clinically with Lyme disease and received two 10-day courses of doxycycline, but continued to suffer from fevers, chest pressure, a dry cough, along with malaise and arthralgia.

The man was subsequently diagnosed with Still’s disease, as he met the criteria with a fever greater than 102.2°F for at least 1 week; a characteristic rash; a white cell count of at least 10,000; lymphadenopathy, and elevated liver transaminases.

He was treated successfully with intravenous steroids and anakinra (a humanised interleukin-1 receptor antagonist), which is used to modulate the immune system.

Author’s Takeaway:

“For the first time, we describe a case of AOSD precipitated by Lyme disease.”

“Lyme disease is a rare trigger of adult-onset Still’s disease, likely mediated via immune system inflammatory activation.”

“AOSD presented with a rare manifestation of haemorrhagic pericarditis and tamponade.”

“We believe that the immunological response to Lyme disease may have triggered AOSD via a hyper-activated immune system.”

    I too have been diagnosed with Stills disease after contracting Lyme disease back in March 2021. I live in Wasaga Beach Ontario Canada. I took doxycycline for 5 weeks and then was prescribed Anakinra daily injection. I have been on the daily injection for one year now.
    Do you think there is any chance that this will ever end or is it for life .
    Thank you

    This interesting. For years I had sore shoulders
    feet and neck, eyes conjunctivitis issues, random fatigue and weakness,, inflamed lymph nodes in neck (Lymes meningitis), and general inflammation. When I got bit by a tick again and finally had “bullseyes” over my body. I was treated with doxycycline and felt like a new man. All symptoms just disappeared. Now a year later I have most of the symptoms back and a photosensitive rash on my scalp and forearms. I have been diagnosed with an autoimmune reaction of which the doctors are unfamiliar with. I have amazed my doctor and that is probably not what I was going for. I will now see a Rheumatologist to hopefully get more answers. I have not yet had a full discussion about what I feel is an association between what I have been feeling the last few years and Lymes and this autoimmune reaction. I do a lot of landscaping and other outdoor activities so just avoiding the sun is out of the question and just plain strange.
