Benha Med. J. 11(3):235-242 Sept. (1994). A study of intestinal parasitic infections in children with bronchial asthma. Abdul-Hamid S. El-Hamshary, Rabaa M. Abdul-Hady, Mona E. Nasr and Ibrahim Nagaty In order to study the relation between intestinal parasites and bronchial asthma 75 cases of children having a history of bronchial asthma and 75 control cases, without any respiratory problems were taken from the out and inpatient clinic of Benha University Hospital. All cases were subjected to full clinical, parasitological examination of stool (simple smear-formol ether concentration-floatation technique- perianal swab- stool culture) and sputum (simple smear- concentration technique) and complete blood picture. Results showed that intestinal parasites were present in 50 cases of asthmatic group and in 44 cases of non asthmatic control. This difference was statistically insignificant. Eosinophilia was present in both asthmatic children and parasitically infected children. It is suggested that there is no causative relation between intestinal parastitism and bronchial asthma.
