Abstract:
Objective To investigate the clinical features of X-linked agammaglobulinemia (XLA)in children,and to improve the early diagnostic rate.Methods The medical records of 11 children with XLA between Dec 2003 and Nov 2011 were reviewed.Results The smallest age of 11 cases with XLA presenting the first symptoms was 0.4 years old and the oldest age was 4 years old with a mean of 2.4 years old.The first diagnosis time was at the age of 3.5 to 13 years old,with a mean of 7 years old.The age at first diagnosis in 63.6% ( 7/11 ) of patients was more than 7 years old.Two patients ( 18.2% ) had the family history of the similar disease.Two patients were died from the infection and 1 patient was missed.The other 8 patients were survived.Respiratory infections occurred in 100% of the 11 patients.54.5% (6/11 )of the patients were suffered with otitis media and digestive infections were seen in 36.4% (4/11 ) of the patients.The levels of lgA,IgM and IgG in the serum of the pauents were all decreased.The levels of IgG in the serum of 9 patients were less than 2 g/L and in the serum of the other 2 patients were less than 2.4 g/L.The levels of CD19 in the serum were all less than 1% and an inversed ratio of CD4/CD8 was observed in 9 patients.Eight patients were diagnosed as XLA by gene detection.Conclusion The age presenting first symptoms in children with XLA in this study is earlier than the reported data and the age at first diagnosis is later.Respiratory infection is the most common manifestation.High prevalence of otitis media and digestive infections are common.The patients with XLA rarely have the family history.The early diagosis and long-term treatment with the intravenous immunoglobulin may improve the prognosis of XLA.
