At Last – A Treatment For Jaw Osteonecrosis

Osteonecrosis mandible from mostly IV biphosphamates can be a real hazard in cancer treatments – now it looks like teriparatide – human recombinant pararthyroid hormone peptide 1-34 – was able to help recovery

Successful treatment of advanced bisphosphonate-related osteonecrosis of the mandible with adjunctive teriparatide therapy.
Lee JJ, Cheng SJ, Jeng JH, Chiang CP, Lau HP, Kok SH. abstract

  • “78-year-old osteoporotic woman with osteonecrosis of the mandible related to alendronate therapy”
  • “daily subcutaneous injection of 20 microg teriparatide, as usually recommended for treatment of osteoporosis”
  • “RESULTS.: The oral mucosa completely regrew, and pain subsided 4 weeks after the initiation of teriparatide administration. Progressive bone regeneration was found during and after the 6-month period of teriparatide therapy”

Comment – looks great but debridement is necessary to area. Won’t be cheap.

addendum:

There is evidence that drugs like pamidronate allow bacteria to stick to bone better and cause an osteomyelitis:

Long term antibiotics can produce healing combined with local treatments: – only B groups results are shown as they got 100% recovery

  • “surgical procedure consisted of sequestrectomy, block resection , bone surface smoothing, surgical cleaning of periodontal pockets and root surface
    smoothing of the adjacent teeth, extraction of teeth that needed removal, and a tension-free soft tissue coverage”
  • “Preoperatively antibiotics were given intravenously for a median of 1 to 3 days and after operation for a median of 7 days
    (Table 3). After discharge from hospital, oral antibiotic therapy followed. “
  • “Sutures were removed after the 14th day if necessary. Sutures that could not be removed easily were left for self-resorption.”
  • “In addition, chlorhexidine mouth rinses 0.12% (CHX) once a day were recommended.”
  • “median duration of preoperative antibiotic therapy was 31 days (23 to 54 days) orally and 1 day intravenously (1 to 3 days). Postoperatively,
    the patients received antibiotics intravenously for 7 days (3 to 14 days) and afterward orally for another 12 days (5 to 47 days;”
  • “Further antibiotic therapy was adjusted to the antibiogram-resistogram profile if necessary. Fluconazole (Diflucan 50; Pfizer, Berlin, Germany)
    was added for 3 to 4 weeks if microbiologic findings showed Candida”
     
  • Comment – there is strong usage of sultamicillin (a peniciliin plus a beta-lactamase inhibitor)- a Phizer product Unasyn that  ?could be gotten by emergency release though I did find an out of country site for purchase:
