X-linked agammaglobulinemia (XLA) is caused by mutation in the gene coding for Bruton's tyrosine kinase (BTK), which impairs peripheral B cell maturation and hypogammaglobulinemia. In this report, we present a case of XLA in a 22-year-old adult male. Genetic testing revealed a novel mutation located at the conserved region (c.383T>C). The patient had a history of recurrent respiratory tract infection which eventually progressed to chronic type II respiratory failure. Several pathogenic bacteria were isolated on culture of respiratory secretions obtained on bronchoscopy. The patient improved on treatment with antibiotics.
X连锁无丙种球蛋白血症(XLA)由编码布鲁顿酪氨酸激酶(BTK)的基因突变引起,该突变会损害外周B细胞成熟并导致低丙种球蛋白血症。在本报告中,我们介绍了一名22岁成年男性的XLA病例。基因检测发现一个位于保守区域的新突变(c.383T>C)。该患者有反复呼吸道感染病史,最终发展为慢性II型呼吸衰竭。支气管镜检查获取的呼吸道分泌物培养分离出几种病原菌。患者经抗生素治疗后病情好转。
