Abstract
AIM
The recognition and diagnosis of primary immunodeficiency disorders (PIDs) is challenging in developing countries. This study aimed to describe the features of PID patients in a tertiary care setting in Egypt and analyse the distribution, clinical features and outcome of PID among paediatric patients.
METHODS
This cross-sectional retrospective study was conducted between January 2016 and January 2021, to evaluate all paediatric patients aged below 18 years with PID that were diagnosed according to the International Union of Immunological Societies 2017 classification. We retrospectively studied the clinical features, diagnostic spectrum, laboratory investigations and relevant immunological workup, and treatment options.
RESULTS
A total of 61 PID patients were enrolled in the current study. The median age at diagnosis was 22 months. The overall consanguinity rate was 49.2%, and the family history of PID was 19.7%. Among all PIDs, the combined immunodeficiency with syndromic features predominates with 17 cases, accounting for 27.9% of all cases of PIDs. The predominant antibody deficiency was the second common PID that was diagnosed in 14 patients (23%). Recurrent pneumonia was the most common initial presentation, occurring in 77% of patients, followed by failure to thrive (63.9%), and recurrent otitis media (55.7%). The total deaths were 18 patients (29.5%).
CONCLUSION
Paediatric patients with PIDs are not uncommon in Egypt. There is a need to improve PID diagnosis and treatment, for better estimation of PID and to decrease morbidity and mortality.
