Hi - DS6 just had IVig a few days ago. He has been doing very well except for flares during exposure. This 2nd IVig was to try to take care of the flares. Otherwise, he has progressed very well since the 1st IVig last Sept. The doc wants to have him take a run of 30 days Clyndo and 14 days Rifampin, together. She wants us to start it now in roder to "blow out any residual Strep that might be left". His titres have been elevated, but not too bad: Anti-DNase 355 and ASO now normal this time, but both or at least 1 are generally elevated to a minor degree at various blood draws every 3 months. Nothing blaring. His other doc, an immunologist, feels that this abx therapy is unnecessary and says that if he had an active infection we would know about it because he wouldn't be doing so much better. DS is currently on a combo of Augmentin and Azith daily, has been for 2 years, and we know he can tolerate abx pretty well. I am just not convinced that these big gun abx are safe - just do not know a lot about them. Any thoughts, advice?
