886 Varicella Complicated with Lobar Pneumonia and Parapneumonic Pleurisy

Background and Aims Chickenpox is an acute, benign, highly contagious disease characterized by generalized vesicular exanthema with self-limited evolution. Pneumonia is the most serious complication of varicella, occurring more frequently in adults (>20%) than in children. An outbreak of the disease started in late autumn 2011 in Romania and continues in present. Methods and results: The authors present the case of a 4 years old boy admitted into the Infectious Diseases Hospital with chickenpox. On the 4-th day of the disease high fever, dyspnea with tachypnea, intercostal retractions, pleuritic pain and cough appeared and the patient was transferred to the Children Hospital. Clinical examination showed abolished left basal vesicular breath sound with wet crackles in the middle and superior lung area; chest X-ray finded inferior left lobe pneumonia and mild pleural effusion. Tracheal aspirate culture was negative. Leucokytosis with neutrophilia and increased ESR and C-reactive protein was founded. Broad spectrum antibiotherapy was started with favourable evolution after 3 weeks. Conclusions Among the most serious complications of varicella is pneumonia; it is less common in children than in adults but it may lead to death. However, the epidemic status in Romania in 2011–2012 was associated with an increased number of viral pneumonias; in our case the radiological aspect was highly suggestive for a secondary bacterial infection even with negative aspirate culture (explained by prior antibiotherapy). The history for chickenpox vaccine was negative in our patient. In Romania, the chickenpox immunization is not included into the National Programe of Immunisations at this moment.
