These observations may be extendable to other conditions in which trauma is purposefully administered (chemotherapy, radiotherapy, surgery for inflammatory bowel disease) to depleted patients.

Chlamydia trachomatis and wheezing SIR,-Dr Bavastrelli and colleagues (May 9, p 1174) report wheezing simulating asthma in 7 children who had evidence of Chlamydia trachomatis infection diagnosed either by isolation on McCoy cell culture and/’or by direct fluorescent antibody testing of conjunctival or pharyngeal swabs. They report that asthmatic symptoms were eradicated in all 7 children after anti-chlamydial antibiotic therapy. Because this information is potentially very important, further details of these patients would be helpful. In particular, what clinical characteristics differentiated these children from "true" asthmatics? Bavastrelli et al report that these children did not respond to bronchodilator agents. Are they referring to inhaled adrenergic agents, theophylline preparations, steroids, or others? Were pulmonary function tests done? It is important to note that the cited high childhood rates (26.7% and 47. 2%) of C trachomatis seroprevalence are mostly due to crossreaciivity with C pneumoniae.1 Bavastrelli et al state "C pneunzorziae strain T W A R grows only on HeLa 229 cells and not on the McCoy cells we used for our isolation procedures". C pnetanomae does grow on McCoy cells, albeit not as readily as on HeLa 229 cells. McCoy cells have been used successfully to isolate .2 the organism in serologically confirmed C pnewnoniae infection The direct fluorescence antibody test for C trachomatis is speciesspecific only if the fluorescein-conjugated major outer membrane protein antibody is used.

SIR,- The children we investigated had, besides the presenting expiratory wheezing, persistent dry cough, chest hyperexpansion, no fever, often conjunctivitis, and eosinophilia. The picture could hardly be differentiated from atopic asthma on clinical grounds alone, but in all children IgE was not raised and none showed specific responses to common allergens, on RAST or symptom of
treated with oral betamethasone sodium
phosphate, others with a mixture of beclomethasone dipropionate plus salbutamol by inhalation. With these treatments the wheezing persisted unmodified, but was eliminated by one or two courses of 2-week amacrolide. Pulmonary-function tests were not obtained. The direct fluorescence antibody test we used, in parallel with culture on McCoy cells, was Microtrak (Syva), which is based on monoclonal antibody raised against the fifteen serotypes of Chlamydia trachomatis that do not cross react with C pneumoniae. Moreover, C pneumoniae is more common in adults and is rare in childhood.’1 The conjunctival involvement in six of our seven patients, with ocular symptoms in four, favours a C trachomatis aetiology. Furthermore, C trachomatis was present in the urogenital tract or in the conjunctiva of the children’s parents, whereas TWAR does not appear to be a sexually transmitted disease or an important cause of
emerging from our data, perhaps worth is that C trachomatis infection should be suspected emphasising, and diagnosed not only in the child with wheezing but also in other members of his family. In fact, we have an additional duty to prevent reinfection by eradicating C trachomatis from the entire family. We agree that more data are needed to draw definitive conclusions, but we think that it was worth publishing out preliminary observation at a time when possible respiratory involvement by C trachomatis is emerging in bronchiolitis or pneumonia in children.3 message
