Invasive pneumokokkinfeksjoner hos barn fra Troms, Nordland og Sör- Tröndelag 1980-95
Sammanfattning
X : Invasive pneumococcal infections may be severe. We have examined epidemiology, risk factors and outcome of these infections. In the years 1980-95, 76 children below the age of 15 with invasive pneumococcal infections were admitted to the hospitals in the counties of Troms, Nordland and Sør-Trøndelag in Norway. The incidence rate in children 0-2 years old was 10.3 cases per 100,000 persons per year, and 1.8 in children 3-14 years. Of the patients 24 had meningitis and 52 bacteraemia. All bacteriological isolates were sensitive to benzylpenicillin. Seven patients died and five developed sequelae. Thirty-one of the children had risk factors prior to the infection. Children with hypo- or hyperventilation at the time of arrival, and/or impaired circulation fared worse than those with normal findings. Children with underlying risk factors have a much higher frequency of invasive pneumococcal infections than other children. Patients who had impaired circulation or ventilation on admission have a bad prognosis for healthy survival.
