@entity1 @entity154 @entity281 @entity465 @entity1200
INTRODUCTION: Sixty-four @entity465 @entity1 were registered at the Pediatric Allergy and Immunology Department, @entity1 's Hospital, Ain Shams University, Cairo, Egypt. DATA: @entity465 were the most common category (35.9%) followed by combined T- and B-cell @entity465 (29.7%), other well defined @entity465 syndromes (18.7%), @entity154 of phagocyte number, function or both (12.5%), and @entity1200 (3.1%). The most frequent disorder was common variable @entity465 (18.7%). The mean age at diagnosis was 29.9 months. The consanguinity rate was 62.5%. Recurrent severe @entity281 were seen in all categories. Fifteen @entity1 died (23.4%) from @entity281 with the highest mortality for combined T- and B-cell @entity465 (15.6%). CONCLUSIONS: @entity1200 are not rare in Egyptian @entity1 . The observed frequency of combined T- and B-cell @entity465 in our cohort is relatively higher than other countries. It is a prerequisite to establish a national registry of @entity465 in Egypt.
