My daughter is 16 mths. old and was diagnosed at three months of age due to failure to thrive. (She is pancreatic insufficient, takes CREON 5 and recently had a g-tube placed. ) At six months, she was hospitalized with a chest infection and a bronchoscopy was done. She cultured positive for pseudomonas but was not treated for it because our pulmonologist believed her infection was due to a virus not the pseudomonas ????? (We have since switched to another pulmonologist) When she began retracting and coughing soon afterward we began a round of Cipro and Tobi. She continued the one month on and one month off schedule of Tobi for three months. She always did relatively well while on the Tobi but within two weeks of being off it, she would get sick again. By "sick" - I mean, the retracting would become more evident, cough would slowly increase . . . it was always a gradual process. She continued to get throat cultures every 2-3 months but never cultured positive for pseudomonas again. She cultured positive for Staph. during another hospital stay where she received 14 days of I.V. antibiotics. Even after the round of I.V. antibiotics, she was sick again in two weeks. She did another round of Tobi and did fairly well during the month of June. I attribute this also to the g-tube placement and the supplemental nutrition she is receiving. Just when I thought that we were finally getting out of the "hole" that we have been in since the initial diagnosis, she is now sick again. She is now on Bactrim, Cipro, Orapred, Albuterol, Pulmazyme twice a day, Flovent. And - she is still not culturing positive for anything. However, her retractions are more severe and her cough is progressively getting worse. We give her CPT three times a day religiously.Our CF team believes that because of her symptoms she should be treated for pseudomonas despite the negative cultures. She will begin Tobi again tonight and if no improvement is seen soon, she will probably receive I.V. antibiotics again. I guess the reason I am posting today is out of sheer frustration and anger. Anger with this disease that keeps getting the best of us. Anger at seeing what happens to my daughter, my family (we have two other daughters, no CF, ages 3 and 5), and myself when she gets ill. When I should be sleeping,I find myself searching sites and message boards to find someone in a similar situation - with a child so young, who already has a g-tube, repeated hospitalizations, pseudomonas ... I don't know why ... maybe so I won't feel so isolated ... maybe so I won't feel that she has a severe case ... maybe so I won't fear the future so much. Rebekah - in reply to your inquiries about future chest infections: Since your son has cultured pseudomonas they probably will treat any flare up - increase in cough, retractions - with Cipro or Tobi. In my daughter's case these flare-ups have always been a gradual process not an abrupt illness and she has never had pneumonia. The important thing is to maintain a high level of nutrition. Studies have shown that good nutrition from birth to age three improves lung function down the road. Good luck and take care.Maria - mother of beautiful Samantha
