A case report: the antibiotic roxithromycin induces PR in a patient with smoldering myeloma

Well…Well…WELL!!! I’ve got a very interesting item for you today…

Many many many thanks to my blog reader Charlotte for this gem: goo.gl/hMsWov

The link will lead you to a case report about a 86-year-old patient (with IgA lambda smoldering myeloma) who went into partial remission after taking roxithromycin, an antibiotic, for just ONE MONTH. This happened last year in New Zealand.

The patient’s paraprotein, which had been increasing since he was diagnosed in 2008, dropped from 46 g/L to 20 g/L.

That’s a 57% decrease! Wowsie.

And another thing: in addition to his other markers remaining stable (calcium and creatinine, e.g.) in the four months after taking roxithromycin, his hemoglobin increased to 132…from 97. Another wowsie.

I also discovered something else: the antibiotic clarithromycin has been found to have anti-myeloma activity BUT only in association with other drugs (dexamethasone, etc.). That’s the difference between the two antibiotics, since roxithromycin appears to have “significant single-agent anti-myeloma activity.” That is, it goes after myeloma all by itself…

I’m not a big fan of antibiotics, that’s for sure (although when you need ’em, you need ’em!!!), but this case report has certainly given me food for thought…

A lot of food for thought…

  1. could be because chronic infections are known triggering agents for initiating SMM. Get rid of the infection (especially early enough in cancer formation), then get rid of SMM.

  2. The macrolides have anti inflammatory/Pleiotropic effects/activity. So do the tetracyclines, minocycline and Doxycycline.

    There a cancer centre in London which is using doxycycline and other old existing, low cost, well tolerated medicines to treat cancer-drugs in combination with chemotherapy . They seem to have good success.

    They use a mix of drugs: statins, Metformin, Mebendazole (Vermox-a deworming tablet-cheap as chips) cimetidine, Itraconazole, Isotretinoin. They also do constant research.

    Care Oncology Clinic in London.

    And then there is this-The professor who ‘cured’ his cancer with a cocktail of everyday pills and 20 years on remains disease-free. Admittedly he had neuroblastome but this is usually a fatal cancer.

  3. The good news is that early-stage laboratory experiments and clinical studies, as well as large scale epidemiological research point to the potential cancer-fighting properties of dozens of existing medicines that millions of people take safely every day for other ailments. Aspirin is the most high-profile example. Research funded in part by Cancer Research UK shows that it can significantly cut the risk of bowel, throat and stomach cancer if taken daily by people aged 50-65 (although the CRC warns on its website that aspirin can have side effects and should not be taken regularly without medical advice).

    The Repurposing Drugs in Oncology (ReDo) Project, an international collaboration between the Anticancer Fund and US-based non-profit organisation Global Cures has identified 70 potential agents for which there is evidence of cancer-fighting properties. These include the diabetes tablet metformin, cholesterol-lowering statins, the antacid cimetidine, the de-worming tablet mebendazole, the anti-fungal itraconazole, and all the drugs Professor Williams took as he battled his brain tumour.
