Question: Pneumonia with no fever


 Khalil - Sun Mar 29, 2009 2:56 pm

My son is 5 months old. 10 days back he developed whistling breathing with chest whizzing. He was diagnosed as having allergy and was given Decadron (Cortizon-bsed infant drug). When the symptoms continued for 5 days, a chest X-ray was done and he was diagnozed with Pneumonia taking 3/4 of the right lung. He never had fever, he was all the way active, though had lack of apetite for 3 days.

Doctors treating him were puzzeled by the fact that this baby has this X-ray as normally in such babies they are in hospital already.

He's being treated now by antibiotics at home. A blood exam yesterday was normal with no infection shown.

We are puzzled. Is there a Pneumonia with no fever? Are the X-ray symptoms of his right lung due to Cortizan?

User avatar Hello --

There are two reasons, as a rule, that a pneumonia may present without fever. First, some viral pneumonias simply never rise to the level of febrile, although with such a large amount of one lung involed this is surprising. There is a second possibility too, however. There is a form of pneumonia known as bronchiolitis obliterans organizing pneumonia or B.O.O.P. This is not an infectious pneumonia and usually will not trigger a fever (although it can). This type is usually of unknown cause, but is frequently found to be due to some inhaled or ingested substance which happens to trigger it.

There is also a possibility that, if cortisone (as Decadron) was administered, this may have suppressed any fever entirely, and this is the most likely cause of this in your son's case. Since steroids suppress inflammation they also suppress fever, and this is probably why, by the time pneumonia was diagnosed, there was no fever.

I hope this answers your question. Best of luck to you.
