That inhaled corticosteroids (Becotide) could impair the growth of some children with asthma – contrary to establish teaching.

As I noted in the introduction to the First Original Observation section of this website, there are advantages for a clinician personally seeing and treating many patients over a prolonged period. A prolonged period is necessary to observe the effects of any interventions. A wise observation of that great physician Sir William Osler is relevant to the following section –“ Medicine is to be learned by experience; and is not an inheritance; it cannot be revealed. Learn to see, learn to hear, learn to feel, learn to smell, and know that by practice alone can you become expert”. One could also add the value of continuity of care – sometimes sadly lacking in modern times.
Hence my enthusiasm for seeing as many patients as possible in clinics where one could improve knowledge of a condition and observe where improvements and changes in management were needed. Certainly in 1968, when I was first appointed as an NHS consultant paedaitrician, there was room for improvement in many areas.
All three original observations were the result of accumulating considerable experience derived from personally following, investigating or treating many children with a particular condition. The importance of significant patient numbers, careful follow-up and note-taking and particularly continuity of personal professional involvement are of great importance. Good care is a team effort. The care and dedication of the nurses and other professional staff in the paediatric clinics and wards and the skill, interest and collaboration of people in many other departments at St James’s in Leeds was of crucial importance in providing a effective professional service and bringing these observations to eventual publication.
As a general paediatric consultant appointed in the late Sixties it was to be expected there would be many children with asthma of varying degrees of severity refered to my outpatient clinic. As my experience increased and the numbers of children with asthma attending my outpatients mounted, on moving to St James’s in 1980 I devoted a regular outpatient session to children with asthma.
We published a number of papers on various aspects of asthma during the Eighties and I also was invited to give postgraduate talks on the subject around the country.

There was a very efficient paediatric outpatient clinic at St James’s with one of my regular session devoted to children with asthma. The clinic was run by an efficient Sister and experienced Nurses who appreciated the importance of careful weighing and measuring each child in minimal clothing on every attendance; the height was measured very accurately with a Harpenden Stadiometer. The results were recorded on a standard outpatient asthma follow-up form. Simple respiratory function tests using a peak flow meter were carried out each attendance. When the child came in to see the doctor (always myself or my Registrar) the recorded height and weight were charted by the doctor on the child’s Tanner growth chart.

This routine became a permanent method of accurately documenting and recording the child’s progress. It was following the child heights recorded on these charts over a number of years that first drew my attention to the fall off in growth of some children who were receiving inhaled corticosteroids. We had been assured in publications by paediatric respiratory experts such as Simon Godfrey that inhaled steroids did not affect growth. Nonetheless, in some of our children, despite a marked improvement of their asthma, there was a slowing of height gain but normal or even accelerated weight gain – and many of these were children in mid-childhood and nowhere near puberty.
So I decided to look at our whole clinic to see if other children had changes in growth rate. The co-authors were Dr Andrew Johnson a scientist from the University Department of Medicine at St James’s, Dr Phoebe Edwards a general practitioner who worked with me for two days a week and Ann Littlewood SRN, a nurse who was responsible for the unit’s clinical computerised database.
We reviewed 346 children with asthma attending my outpatients, 81 of whom were receiving inhaled beclomethasone in doses ranging from 200 to 800 ug daily. Those receiving the inhaled corticosteroids had significantly lower height standard deviation scores than those not on steroids. The slowing of growth in some was quite obvious on the growth charts.
For example although Balfour-Lynn had noted a high prevalence of delated puberty he had not noted adverse growth effects with inhaled corticosteroids with doses up to 600 ug daily (Balfour-Lynn L. Growth and childhood asthma. Arch Dis Child 1986;61:1049-55).
It was noted that there was a difference in age between the two groups and it was suggested the difference could be related to the natural pattern of prepubertal growth declaration seen in older corticosteroid treated patients. There were quite strong objections to our findings from a number of colleagues.
