İnfluenza virüsü (H1N1)'ne sekonder gelişen miyokardit olgusu.

Although influenza is an acute and uncomplicated disease, that limits itself in the healthy children, it may lead to death by rarely forming the sickness. The most common complication of influenza is pneumonia and it is a rare complication which is developed together with myocarditis by influenza A and B viruses. A 32 months-old male patient was admitted for rapidly developed respiratory distress and tachycardia after fever, cough, vomiting, malaise and runny nose. His general status was medium, he had conscious and had hepatomegaly, tachycardia, dyspnea, tachypnea, intercostal-subcostal retractions and bilateral rhonchus. Cardiac enzyme levels and other laboratory parameters were found normal. Myocarditis and ejection fraction was determined as 42% in echocardiography. However, hospitalization hours between 24 and 48, the patient, whose significant respiratory compromise developed, was intubated and fastened to a mechanical ventilator. H1N1 is produce in nasopharyngeal swab culture at the sixth day of follow-up. Because we think H1N1 virus was responsible from current myocarditis, oseltamivir treatment was initiated. In the fourth day of the treatment the patient's fever returned to normal, in the ninth day a dramatic recovery was observed. In tracking echocardiography, a significant improvement was observed in the ejection fraction and myocarditis picture compared with admission time. This case was presented in order to remind that in a patients, who present with influenza findings but have respiratory distress and tachycardia in addition to lower respiratory tract infection, myocarditis should also be considered in the differential diagnosis and to remind that promising results could be obtained with the early diagnosis and treatment.
