Dr. Deutsch said that at Cincinnati Childrens Hospital and the other medical centers that participated in the study, the new classification system is helping pathologists diagnose childrens lung disease more accurately, leading in some cases to more appropriate treatment.
For instance, in the past, children with lung growth abnormalities might have been treated as though they had ILD and given steroids, which may not be an effective treatment for them.
The new system also gives doctors more information about an infants prognosis. In the past, children with ILD were thought to have a high rate of illness and death. The classification system can help doctors distinguish certain children who may appear very ill, but who have a high chance of recovery (such as children with pulmonary interstitial glycogenosis and neuroendocrine cell hyperplasia of infancy), from those with a particular genetic mutation, known as ABCA3, who are unlikely to recover on their own and may need a lung transplant, Dr. Deutsch said.
This new system gives clinicians, radiologists and pathologists a structure upon which to base diagnoses in a uniform fashion well all be reading from the same book, said Andrew Nicholson, M.D., consultant histopathologist at Royal Brompton Hospital and professor of respiratory pathology at the National Heart and Lung Institute Division of Imperial College School of Medicine in London, who co-authored an editorial accompanying the study with Andrew Bush, M.D.
The next step is for researchers at other medical institutions and in other countries to test the new system to see how applicable it is to their patients, Dr. Nicholson said. Pathologists should review other cohorts of cases to see if any disease groups are missing, or if others a
