Tract Disease

DURING the past ten years there has been an exponential increase in our understanding of the etiology and epidemiology of acute respiratory disease. Unfortunately development of the means for control of these illnesses has not kept pace with etiologic or epidemiologic understanding. In this presentation an attempt will he made to summarize the role of a number of viruses and mycoplasmas in acute respiratory disease of infancy and childhood. In addition the ecology of such infections will be discussed, particularly those aspects of infection which have relevance to the problem of immunoprophylaxis. Much of the information to be discussed is derived from studies at the Children's Hospital of D.C. and the Junior Village Welfare Nursery of D.C. In many instances similar findings have been reported from other localities so that the conclusions which can be drawn from the Washington, D.C., studies would appear to have more than local significance. Since the Washington D.C., studies represent the longest continuous inquiry into the nature of acute pediatric respiratory disease primary emphasis will be placed on the interpretation of these findings. Bacteria Although group A beta hemolytic streptococci play an important role in upper respiratory tract disease it would appear that these organisms are relatively unimportant in the more serious types of illness in which lower respiratory tract involvement occurs. The careful studies of Babe, Beem, and co-workers indicate that pathogenic bacteria are not important primary etiologic agents in lower respiratory tract disease of infancy and childhood. For this reason major emphasis in this presentation will be given to the role of viruses and mycoplasmas in respiratory disease.

Human respiratory syncytial virus (RSV) is the single most important cause of lower respiratory tract disease in infants and young children and a major viral agent responsible for respiratory tract disease in immunosuppressed individuals and the elderly, but no vaccines and antiviral drugs are available. Herein the recombinant RSV (rRSV) encoding enhanced green fluorescence protein (EGFP, rRSV-EGFP) was constructed and the potential for screening anti-RSV drugs was investigated. The recombinant plasmid of pBRATm-rRSV-EGFP, containing T7 transcription cassette composed of T7 promoter, RSV antigenomic cDNA with EGFP gene, HDV ribozyme (δ), and T7 terminator in the order of 5′ to 3′, was constructed and cotransfected into BHK/T7-9 cells together with helper plasmids encoding N, P, L, and M2-1 gene, respectively. The rescued rRSV-EGFP was confirmed by increasing expression of EGFP over blind passages and by RT-PCR. rRSV-EGFP was comparable to the other two recombinant RSVs encoding red fluorescent protein (RFP, rRSV-RFP) or luciferase (Luc, rRSV-Luc) in the growth kinetic, and there was a difference in sensitivity between them for screening anti-RSV agents based on infection of HEp-2 cells. The EGFP-encoding rRSV has been constructed and rescued successfully and has the potential for high-throughput anti-RSV drug screening in vitro.

Respiratory Tract Colonization

Respiratory tract colonization with Chlamydia trachomatis commonly occurs in natally acquired chlamydial infection and is sometimes associated with a chronic, afebrile pneumonia that has relatively distinctive clinical characteristics. To further define the frequency and clinical characteristics of lower respiratory tract disease associated with C trachomatis, we grouped 56 infants aged less than 6 months with afebrile pneumonia according to nasopharyngeal shedding of Chlamydia and viruses and compared their illnesses. Forty-one (73%) were positive for C trachomatis (23 had C trachomatis only, while 18 had C trachomatis plus a virus [cytomegalovirus, respiratory synctial virus, adenovirus, rhinovirus, or enterovirus]), and 15 were C trachomatis negative (nine had a virus only, and six had neither C trachomatis nor virus). The 41 infants with C trachomatis alone or C trachomatis plus a virus were similar clinically and differed significantly from other infants in several ways: (1) onset of symptoms before 8 weeks of age; (2) gradually worsening symptoms; (3) presentation for care at 4 to 11 weeks of age; (4) presence of conjunctivitis and ear abnormalities; (5) chest roentgenograms showing bilateral, symmetrical, interstitial infiltrates and hyperexpansion; (6) peripheral blood eosinophils ≥300/cu mm; and (7) elevated values for serum immunoglobulins M, G, and A.
