Could This Treatment Method Help Those With Persistent Lyme Disease?

I know of a number of people in NY and NJ who have been struggling for years with persistent Lyme disease. So this research with the possibility of treatments that actually work is fantastic. And it gives support to all those people who say they still have Lyme disease after antibiotic treatment, but the medical establishment says they're wrong -  that it's all their mind or due to something else. Yes, they still have Lyme disease from persister cells that avoided the antibiotic treatment! Persister cells are drug-tolerant,dormant variants of Borrelia burgdorferi  (the bacterium that causes Lyme disease). And perhaps pulse-dosing antibiotics may work to get rid of the persister cells. The antibiotic they successfully used in the research is ceftriaxone (a cephalosporin antibiotic) - but only in cultures grown in a lab. Further research is needed. From Science Daily:

Researchers' discovery may explain difficulty in treating Lyme disease

North­eastern Uni­ver­sity researchers have found that the bac­terium that causes Lyme dis­ease forms dor­mant per­sister cells, which are known to evade antibi­otics. This sig­nif­i­cant finding, they said, could help explain why it's so dif­fi­cult to treat the infec­tion in some patients.

In other chronic infec­tions, Lewis' lab has tracked the resis­tance to antibi­otic therapy to the pres­ence of per­sister cells--which are drug-tolerant, dor­mant vari­ants of reg­ular cells. These per­sister cells are exactly what they've iden­ti­fied here in Bor­relia burgdor­feri, the bac­terium that causes Lyme disease.The researchers have also reported two approaches--one of them quite promising--to erad­i­cate Lyme dis­ease, as well as poten­tially other nasty infections.

Lyme dis­ease affects 300,000 people annu­ally in the U.S., according to the Cen­ters for Dis­ease Con­trol and Pre­ven­tion, and is trans­mitted to people via bites from infected black­legged ticks. If caught early, patients treated with antibi­otics usu­ally recover quickly. How­ever, about 10 to 20 per­cent of patients, par­tic­u­larly those diag­nosed later, who have received antibi­otic treat­ment may have per­sis­tent and recur­ring symp­toms including arthritis, muscle pain, fatigue, and neu­ro­log­ical prob­lems. These patients are diag­nosed with Post-treatment Lyme Dis­ease Syndrome.

In addi­tion to iden­ti­fying the pres­ence of these per­sister cells, Lewis' team also pre­sented two methods for wiping out the infection--both of which were suc­cessful in lab tests. One involved an anti-cancer agent called Mit­o­mycin C, which com­pletely erad­i­cated all cul­tures of the bac­terium in one fell swoop. How­ever, Lewis stressed that, given Mit­o­mycin C's tox­i­city, it isn't a rec­om­mended option for treating Lyme dis­ease, though his team's find­ings are useful to helping to better under­stand the disease.

The second approach, which Lewis noted is much more prac­tical, involved pulse-dosing an antibi­otic to elim­i­nate per­sis­ters. The researchers intro­duced the antibi­otic a first time, which killed the growing cells but not the dor­mant per­sis­ters. But once the antibi­otic washed away, the per­sis­ters woke up, and before they had time to restore their pop­u­la­tion the researchers hit them with the antibi­otic again. Four rounds of antibi­otic treat­ments com­pletely erad­i­cated the per­sis­ters in a test tube.

"This is the first time, we think, that pulse-dosing has been pub­lished as a method for erad­i­cating the pop­u­la­tion of a pathogen with antibi­otics that don't kill dor­mant cells," Lewis said. "The trick to doing this is to allow the dor­mant cells to wake up.
