Inverse association between Chlamydia pneumoniae respiratory tract infection and initiation of asthma or allergic rhinitis in children.

Pediatr Allergy Immunol 2005 Mar;16(2):137-44

To evaluate the role of Chlamydia pneumoniae respiratory tract infection on pediatric asthma, allergic rhinitis or atopic eczema initiation, children of three age groups (n=1211) were prospectively studied for a C. pneumoniae infection using throat swabs and polymerase chain reaction (PCR) with enzyme immunoassay (EIA) detection. Infected children (study group, SG) were examined monthly until the agent could not be detected, quantifying persistent infection. They were compared with randomly selected, non-infected children without asthma matched for age, gender and origin (control group, CG) regarding lung function and inflammatory parameters as well as initiation of allergic diseases judged by family doctor diagnosis after, in median, 22 months. At the first follow-up examination, SG children revealed a higher leukotriene B4 (median 36 pg/ml vs. 19, p=0.04) and 8-isoprostane (median 15 pg/ml vs. 12, p=0.04) in breath condensate characterizing neutrophil, agent-related inflammation and oxidative stress in the lower airways. Cysteinyl leukotrienes, important in acute allergic inflammation, were without difference. Local, anti C. pneumoniae secretory immunoglobulin A antibodies were higher in children after C. pneumoniae infection (optical density median 0.7 vs. 0.4, p=0.001) confirming PCR-EIA results. At the final examination, there was no difference in pathological lung function tests, parameters of exhaled breath condensate or eosinophilia of the nasal mucosa. Incidence of asthma (0/55 vs. 5/54, p=0.03) and allergic rhinitis [3/53 vs. 10/52, p=0.04, odds ratio and 95% confidence interval-OR 0.25 (0.06;0.98)] as well as prevalence of asthma [1/56 vs. 9/58, p=0.02, OR 0.1 (0.01;0.81)] and allergic rhinitis [6/56 vs. 16/58, p=0.03, OR 0.32 (0.11;0.88)] were lower in the SG children. There was no association in atopic eczema. Three children with persistent infection revealed a slightly higher incidence in allergic rhinitis without significance than those with single C. pneumoniae detection (1/3 vs. 2/50), however, not to the CG. In conclusion a C. pneumoniae upper respiratory tract infection may be regarded as a protective factor for childhood asthma or allergic rhinitis in a population of kindergarten and school-age children.

Tendonitis in variant hyperimmunoglobulinaemia D and periodic fever syndrome--a rare disease with a new symptom.

Eur J Pediatr 2005 Jun 16;164(6):391-4. Epub 2005 Mar 16.

University Children's Hospital, Soldmannstrasse 15, 17487, Greifswald, Germany.

Unlabelled: Hyperimmunoglobulinaemia D syndrome (HIDS) is defined as recurrent fever, generalised lymphadenitis, abdominal pain, arthritis and raised polyclonal serum IgD >100 IU/ml. The cause is a mutation in the mevalonate kinase gene. Other periodic fever syndromes are known. We report a new patient and describe orbital tendonitis as a hitherto unreported symptom

Conclusion: Without any underlying cause, the tendonitis must be seen as new symptom of variant hyperimmunoglobulinaemia D syndrome. We speculate that the inflammation of the Tenon spatium is similar to the process of inflammation of the connective tissue in the joint in hyperimmunoglobulinaemia D syndrome where deposits of C3 and IgM are present. Variant hyperimmunoglobulinaemia D syndrome can be present in one family.
