ABSTRACT
BACKGROUND: Children with acute respiratory tract infection (ARTI) represent an important target group for efforts aimed at reducing unnecessary antibiotic use. OBJECTIVE: To present the epidemiological data and evaluate the effect of clinical, laboratory, radiological and microbiological data on the decision to prescribe antibiotics to pediatric patients with ARTI as well as to seek criteria that would justify antibiotic use. PATIENTS AND METHODS: A retrospective review was made of the clinical histories of 147 previously healthy children, consecutively admitted to our hospital with ARTI for 1 year (May 1996-April 1997). Patients were divided in two groups: those not treated with antibiotics (n = 92) and those treated (n = 55). Data from the two groups were compared with a statistical computer program (R-Sigma). RESULTS: Of the 147 patients studied, mean age was 2.5 years (range 0-14 years) and 85 (58%) males. One-hundred-and-five patients (72%) had previously been attended to in the emergency room, and 45 patients (30%) had been treated with antibiotics. Upper respiratory tract infection was diagnosed in 81 patients (54%), bronchitis in 28 (18%), bronchiolitis in 23 (15%) and pneumonia in 15 (10%). Ninety-seven patients (66%) had viral infection and only two (1%) had bacterial infection. Syncytial respiratory virus was isolated in 41 patients (28%) and adenovirus in 30 (20%). In the untreated group, the longer duration of symptoms before admission, lymphocytosis, clinical diagnosis of bronchiolitis and normal thorax X-ray, were statistically significant. In the treated group, fever, leukocytosis, neutrophilia and a diagnosis of pneumonia were statistically significant. Length of stay was longer in this group than in the untreated group. CONCLUSIONS: It is difficult to prescribe antibiotics on the basis of bacteriologic data. Laboratory, analytic and radiological data can be helpful in the rational use of antibiotics.

Antecedentes: Los niños con infección respiratoria aguda constituyen un grupo permanente de estudio para evitar el tratamiento innecesario con antibióticos. Objetivo: Presentar los datos epidemiológicos y estudiar el efecto que tienen los datos clínicos, analíticos, radiológicos y microbiológicos en la decisión de tratar con antibióticos a niños hospitalizados por infección respiratoria aguda, buscando criterios que justifiquen su uso. Pacientes y métodos Se revisan las historias clínicas de 147 niños ingresados consecutivamente por catarro de vías altas, bronquitis, bronquiolitis y neumonía, durante un año (mayo 1996-abril 1997). Los pacientes se dividieron en 2 grupos: pacientes no tratados con antibióticos (n = 92), y pacientes tratados (n = 55) y se compararon estadísticamente los datos mediante un programa R-Sigma. Resultados En el conjunto de la serie, la edad media fue de 2,5 años con predominio de varones 85 (58 por ciento); habían consultado previamente en urgencias 105 pacientes (72 por ciento) y estaban recibiendo antibióticos 45 pacientes (30 por ciento). Se diagnosticó catarro de vías altas en 81 pacientes (54 por ciento), bronquitis en 28 (18 por ciento), bronquiolitis en 23 (15 por ciento) y neumonía en 15 (10 por ciento). Hubo 97 pacientes (66 por ciento) con infección viral demostrada y 2 (1 por ciento) bacteriana. El virus respiratorio sincitial se aisló en 41 pacientes (28 por ciento) y el adenovirus en 30 (20 por ciento). Entre los pacientes no tratados resultaron estadísticamente significativos la mayor duración de los síntomas antes del ingreso, la linfocitosis, el diagnóstico de bronquiolitis y la radiografía de tórax normal. Entre los pacientes tratados fueron estadísticamente significativas fiebre, leucocitosis, neutrofilia y el diagnóstico de neumonía, siendo así mismo más larga la estancia hospitalaria. Conclusión En nuestro medio, es difícil indicar un tratamiento antibiótico basándose en criterios bacteriológicos; los criterios clínicos, radiológicos y analíticos pueden ayudar en la toma de decisiones (AU)

OBJECTIVE: The aims of this study were: 1) To assess the effectiveness of viral culture and serology. 2) To check if there are clinical differences between patients with viral or bacterial infections. 3) Assessment of treatment, previous to and during the hospital stay. PATIENTS AND METHODS: A prospective study was carried out between January 1994 and June 1995 on 56 inpatients diagnosed of pneumonia. The mean age was 3 years (range: 2 months- 14 years). Viral cultures on cell monolayers was carried out in 46 patients. Serology was carried out in 33 patients older than six months of age. Blood cultures were obtained in 27 patients and a tuberculine reaction was studied in 15 patients. On the basis of microbiological results, three groups were formed (viral, bacterial and unknown) and clinical symptoms, thorax X-rays, and laboratory data were compared. RESULTS: The etiologic agent was detected in 36 patients (64%). The most frequent pathogens detected were adenovirus and respiratory syncytial virus with 11 patients (19%) each, followed by Mycoplasma pneumoniae with 9 patients (16%): Viral cultures were positive in 16 patients (35%) and serology in 22 patients (66%). Viral infection was detected in 20 patients (36%) and bacterial infection in 16 (28%). Mixed infection (bacterial/viral) was found in 5 patients (9%). The patients with viral infections showed significant differences (p < 0.01) for age (younger) and tachypnea compared with those with bacterial infections. Sixty-six percent of the patients had received antibiotic treatment previous to hospital admission and 87% during their hospitalization. CONCLUSIONS: Although the etiologic studies were positive in 64% of the patients, the delay in obtaining the results make them scarcely useful in determining whether to initiate or not antibiotic therapy (87% of inpatients). Clinical data, radiology results and leukocyte counts do not show any difference between viral and bacterial infections.
