An 11-Year-old Male with X-linked Agammaglobulinemia and Persistent Abdominal Pain

Metagenomic next-generation sequencing is a promising tool for detecting pathogens that are difficult to isolate by traditional modalities, particularly in the diagnosis of complex infections in immunocompromised children. We describe a child with X-linked agammaglobulinemia and chronic abdominal pain diagnosed with a multiorganism infection (Helicobacter cinaedi, Campylobacter coli and Parainfluenza) identified by various diagnostic tools, including plasma metagenomic next-generation sequencing.
