Doxycycline for potential(?) vascular stabilization

Postby josh » Wed Jan 14, 2015 12:28 am

Hi All!

(typical disclaimer I am not a doctor, talk to your neuro/doctor before trying anything!)

In the quest for vascular stabilization, doxycycline comes up as a focus of research but far from proven for stabilizing cavernous malformation. But it seems interesting anyway and certainly some basic research in this direction. My apologies if this drug has been discussed before for potential treatment.

Below are some research links (the research on doxycycline seems endless btw) ...

-- "MMP-2 and MMP-9 were more strongly expressed in the vascular walls of CCMs compared to cAVMs for all comparable layers: endothelium, subendothelium and the perivascular space."

-- "Independent of its dose, short-term preoperative doxycycline therapy improves the proteolytic balance in AAA, presumably through an effect on aortic wall neutrophil content. "

MRI in March 2012 shows growth and symptoms worsening (sigh). MRI in Sep 2012 maybe shrinking! New bleed in 2014,CM bigger,recovering OK *meh*
