Recurrent/persistent pneumonia among children in upper Egypt

Abstract

Objectives: Recurrent/persistent pneumonia in children continues to be a major challenge for the pediatricians. The aim of our study was to establish the prevalence and underlying causes of recurrent/persistent pneumonia in children in Upper Egypt. Settings: Assiut University Children Hospital, Assiut, Egypt. Patients and Methods: Patients, admitted for pneumonia to the hospital during 2 years, were investigated with microbiological, biochemical, immunological and radiological tests in order to establish the prevalence of recurrent/persistent pneumonia and to find out its underlying causes. Results: 113 out of 1228 patients (9.2%) met the diagnosis of recurrent /persistent pneumonia. Identified causes were; aspiration syndrome (17.7%), pulmonary TB (14.0%), congenital heart disease (11.5%), bronchial asthma (9.7%), immune deficiency disorders (8.8%) and vitamin D deficiency rickets (7.0%). Other causes included; congenital anomalies of the respiratory tract, interstitial lung diseases, bronchiectasis, and sickle cell anemia. No predisposing factors could be identified in 15% of cases. Conclusion: Approximately 1 out of 10 children with diagnosis of pneumonia in Assiut University Children Hospital had recurrent/persistent pneumonia. The most frequent underlying cause for recurrent/persistent pneumonia was aspiration syndrome, followed by pulmonary TB.
