My son and daughter have atypical cf. My daughter is doing great we do her treatments everyday, she is in school and loving it. My son is 2 and has been sick pretty much his whole life. His sweat test was negative, we did an ambrey test when he was about 8 months old and it came back that he has 7t 7t varient. He has been hospitalized 5 times and 2 picc lines. He has had a fever everyday since Aug 2010. He has tested positve for Staph, psuedomonous,ecoli. and stenotrophomonas multiphila. His white count is always high, it stays around 15,0000 when he is on ivs it comes down this last time after three weeks of tobramycin and ceftazidime it came down to 6,600and a week laterwas back up to 9,600. He is always stuffy and hoarse, the ent doesn't have any answers the meds he put him on didn't work he has had 3 ct scans of his siniuses since March of this year.The ID doctor thinks its viral. and the cf doctor is waiting for him to either get "sick" or culture something again so she can put him back in the hospital and do another bronc. ( had one in Aug 2010). I am fusterated and confused. My sister in law passed away in 2000 from Cf and this all scares me.
