To be fair to rayban, “it’s complicated” and I like to think he’s suggesting that it may not be a long term infection but possibly inflammatory response
I think there’s a bit of science in support of that (CBA looking now). There’s also the difficulty Drs face that there are no quick and dependable tests to show active infection, even before we get to low-level persistence & sessile cells.
(doxycycline in particular is an antibiotic with identifiable anti-inflammatory properties and so you might even stretch to a rationale for it working in the absence of active Lyme infection. The “plaquenil” mentioned in that article is hydroxychloroquine – used to be quite widely used vs rheumatiod arthritis etc because it also modulates chronic immune response)
Look at this recent list from the EMA:
arthralgia, pain in extremities, gait disturbance, neuropathies associated with paraesthesia, depression, fatigue, memory impairment, sleep disorders, and impaired hearing, vision, taste and smell
That’s not Lyme, it’s long-term adverse effects of quinolone antibiotics – been on the market & widely used for, what, 30 years or so and it took that long for an association to be endorsed by EMA (US was a bit earlier)
Those are vague & really common symptoms in isolation or small combinations, experienced often without identifiable causes and that’s why it takes ages to identify common links between people experiencing them. I wonder if anyone’s looked into the drug histories of the chronic Lyme sufferers to see how many had quinolones (ever, not just “for” their Lyme)?
