1. Oksi, J., et al., 1999, Borrelia burgdorferi detected by culture and PCR in clinical relapse of disseminated Lyme Borreliosis. Annals of Medicine, 1999, 31(3):225-32. Of 165 patients treated for disseminated Lyme borreliosis with three months or more of antibiotics (including a minimum of two weeks of ceftriaxone), 32 had treatment failure. At follow-up, 13 patients with clinical relapse were PCR or culture positive (10 PCR positive, 1 culture positive, 2 PCR and culture positive). “In this study, culture or PCR-based evidence for the presence of live spirochetes was obtained in more than 40% of the patients with relapsed disease.” “The treatment caused only temporary relief in the symptoms of the patients.” “We conclude that the treatment of Lyme borreliosis with appropriate antibiotics for even more than 3 months may not always eradicate the spirochete.”

[Abstract:] “The results of our study revealed that Lyme meningitis frequently occurs without meningeal signs and is often accompanied by additional borreliosis persisted or occurred for the first time in several patients. They were not infrequent even at the examination performed one year after therapy.”

treatment of four cases. Acta Cinica Belgica, 1998, 53(3):178-83.

A five-week treatment with doxycycline at a dose of 200 mg daily was prescribed. Fatigue, arthralgia en myalgia seemed to respond positively to the initiated therapy. However, they reappeared two weeks after cessation of doxycycline. …it was decided to treat with ceftriaxone IM 2 g daily for three weeks. This resulted in a complete resolution of the general symptoms. However, three weeks later arthralgia of the knees and myalgia in both legs recurred. …Symptoms and signs may improve only temporarily shortly after treatment, but re-emerge within weeks or months.

[From the abstract:] “Patients with erythema migrans can fail to respond to antibiotic therapy. Persistent or recurrent erythema migrans, major sequelae such as meningitis and arthritis, survival of borrelia burgdorferi and significant and persistent increase of antibody titres against B. burgdorferi after antibiotic therapy are strong indications of a treatment failure. Most, if not all, antibiotics used so far have been associated with a treatment failure in patients with erythema migrans.”

[Persistence:] “…clinical persistence of borrelia burgdorferi in patients with active Lyme borreliosis occurs despite obviously adequate antibiotic therapy…” “The persistence of Bb even after therapy with antibiotics has been demonstrated in cerebrospinal fluid (CSF), in skin, iris, heart and joint biopsies.” [Cysts:] In vitro investigation of morphological variants of B. burgdorferi, in an effort to explain the clinical persistence of active Lyme borreliosis despite antibiotic therapy. The authors suggest that these atypical forms may allow Borrelia to survive antibiotic treatment.

6. Bayer, ME., et al., 1996, Borrelia burgdorferi DNA in the urine of treated patients with chronic Lyme disease symptoms. A PCR study of 97 cases. Infection, 1996, 24 No. 5.

The urine of 74.2% of patients previously treated with antibiotics for Lyme disease was found to be positive for B.burgdorferi DNA using PCR testing. All patients (n=97) had prior documented EM rash and had received a minimum of 3 weeks to 2 months oral or intravenous antibiotics. In 4 patients, PCR results were temporarily negative after treatment, but became positive again 4-6 weeks later. All patients suffered “continuing, often gradually worsening Lyme disease-like symptoms. …it seems to be characteristic for most of the patients in our study that, after antibiotic-free periods of a few months, they had again become increasingly ill with neurological and arthritic symptoms, so that treatment had been resumed.”

[From the abstract:] “The authors report a case of fatal neuropsychiatric Lyme disease (LD) that was expressed clinically by progressive frontal lobe dementia and pathologically by severe subcortical degeneration. Antibiotic treatment resulted in transient improvement, but the patient relapsed after the antibiotics were discontinued. LD [Lyme disease] must be considered even in cases with purely psychiatric presentation and prolonged antibiotic therapy may be necessary.”

“Ten of the 38 patients with Lyme disease reported relapses within 1 year of treatment…and had had repeated antibiotic treatment (5 patients with intravenous ceftriaxone). …Patient 4, in addition, had had second degree atrioventricular block with acute Lyme disease that resolved with penicillin treatment. Her irregular rhythm recurred 2 years later, resolved temporarily with ceftriaxone treatment, but progressed to complete heart block requiring a pacemaker. …Patient 12…was treated with 2 weeks of parenteral penicillin. She later developed a progressive speech disorder, bradykinesia, and abnormal ocular motor function. Magnetic resonance imaging of the brain showed scattered white matter lesions in the hemispheres and pons…she was re-treated with 2 weeks of parenteral ceftriaxone in 1989 that had no effect on her neurologic symptoms. During the time of observation, this patient died. At autopsy…[using] Dieterle silver stain, a spirochete was present in the cortex and another was exterior to a leptomeningeal vessel.”

“[The patient] received 2 g of ceftriaxone daily for 4 weeks. Marked early clinical improvement was observed and continued for 3 weeks after therapy was discontinued. He received 6 additional courses of intravenous antibiotics for 3 to 5 weeks’ duration (penicillin, doxycycline [two courses], and ceftriaxone [three courses], and 1 oral antibiotic (azithromycin). His general condition improved, but each antibiotic course was followed by a relapse.”

167:1074-1081.

This study found that B. burgdorferi spirochetes can survive antibiotic treatment through intracellular sequestion within firbroblasts. “In these experiments, we demonstrated that fibroblasts and keratinocytes were able to protect B. burgdorferi from the action of this B-lactam antibiotic [ceftriaxone] even at antibiotic concentrations > or = 10 times the MBC of the antibiotic. The protective effect was sustained for , or = 14 days and required viable fibroblast monolayers…We have demonstrated the presence of intracellular B. burgdorferi within HF [human fibroblasts] using laser scanning confocal microscopy…The observation of viable spirochetes within fibroblasts coupled to protection of B. burgdorferi from extracellular microbicidal antibiotics by fibroblasts [19] suggests that B. burgdorferi may be among the small number of bacteria that can cause chronic infection by localizing within host cells where they remain sequestered from some antimicrobial agents and the host humoral immune response.”

Borrelia burgdorferi, from ceftriaxone in vitro. Journal of Infectious Diseases,
1992, 166(2):440-4.

[From the abstract:] “The Lyme disease spirochete, Borrelia burgdorferi, can be recovered long after initial infection, even from antibiotic-treated patients, indicating that it resists eradication by host defense mechanisms and antibiotics. …Human foreskin fibroblasts protected B. burgdorferi from the lethal action of a 2-day exposure to ceftriaxone at 1 microgram/mL, 10-20 x MBC. In the absence of fibroblasts, the organisms did not survive…Fibroblasts protected B. burgdorferi for at least 14 days of exposure to ceftriaxone. Mouse keratinocytes, HEp-2 cells, and Vero cells but not Caco-2 cells showed the same protective effect. Thus, several eukaryotic cell types provide the Lyme disease spirochete with a protective environment contributing to its long-term survival.” [From the article:] “An intracellular site of survival would provide protection, since many of the antibiotics are much less concentrated in the cells than in extracellular spaces…Possibly fibroblasts and keratinocytes are the initial sites of this intracellular survival. This is especially relevant in that the first contact between the spirochete and the host in Lyme disease occurs in the skin.” (p.443)

“Spirochetes were visualized in imprint prepareations of freshly thawed frontal lobe cortex with monoclonal antibody H5332, which specifically binds to the outer surface membrane of Borrelia burgdorfer. Borrelia spirochetes were recovered from cultures of freshly thawed cerebral cortex and hippocampus in Barbour-Stoenner-Kelly medium. An unexpected observation was the identification of cystic forms of the Borrelia spirochete in dark-field preparations of cultured hippocampus and in imprints of hippocampus using the monoclonal antibody H9724, which binds to class-specific axial filament proteins of borrelia spirochetes.”

spirochetes in vivo. APMIS, 2001, May;109(5):383-8.

“Cystic forms (also called spheroplasts or starvation forms) and their ability to reconvert into normal motile spirochetes have already been demonstrated in the Borrelia burgdorferi sensu lato complex. The aim of this study was to determine whether motile B. garinii could develop from cystic forms, not only in vitro but also in vivo, in cyst-inoculated mice. The cysts prepared in distilled water were able to reconvert into normal motile spirochetes at any time during in vitro experiments, lasting one month, even after freeze-thawing of the cysts. Motile spirochetes were successfully isolated from 2 out of 15 mice inoculated intraperitoneally with cystic forms, showing the infectivity of the cysts. The demonstrated capacity of the cysts to reconvert into motile spirochetes in vivo and their surprising resistance to adverse environmental conditions should lead to further studies on the role and function of these forms in Lyme disease.”
