Antibiotics and onset of MDS

When I was diagnosed with Diverticulitis in May (pre MDS diagnosis) I was prescribed 2000 mg Metronidazole/day plus 200 mg Cipro/day. I have been doing some research and learned that Metronidazole and Cirpro can cause bone marrow depression/aplasia. Sometimes the symptoms reverse when the meds are stopped and sometimes they do not. I am wondering if anybody knows anything about the connection between antibiotics and bone marrow aplasia?

Just anecdotal, but after 2 years of antibiotics for a bone infection (many different kinds), my husband developed MDS. First the hematologist just thought the antibiotics had suppressed his neutrophils, then other lines were affected.

Oddly enough I first developed anaemia after a long course of both IV and oral antibiotics for severe pneumonia. The antibiotics were given over about three months and I had Amoxil then Augmentin, then Ceftazadine, then Benzylpenicillan then Cipro, Doxycycline, Dicloxicillan and lastly metronidazole for the antibiotic induced diarrhea.

I have always assumed the pneumonia was my first symptom/sign that something was wrong but maybe it was the antibiotics causing the ensuing anaemia and neutropenia.

I will probably never know.

Yes, the doctors really don't really seem to care about the cause, because it's all about moving forward with treatment once it shows up. For a while, we also suspected heavy metal poisoning because Bruce was also exposed to benzene and to pesticides.

I have some anecdotal experience to relate as well

The person was on a heavy dose of ß-lactam antibiotics for 60 days. Following this, the blood counts became very low and eventually was diagnosed with AML - acute myeloid leukemia.
