ᅟ: Helicobacter bilis is a commensal bacterium causing chronic hepatitis and colitis in mice. In humans, enterohepatic Helicobacter spp. are associated with chronic hepatobiliary diseases.
Purpose: We aimed at understanding the microbial etiology in a patient with X-linked agammaglobulinemia presenting with suppurative cholangitis.
Methods: 16S rDNA PCR directly performed on a liver biopsy retrieved DNA of H. bilis.
Results: Clinical outcome resulted in the normalization of clinical and biological parameters under antibiotic treatment by a combination of ceftriaxone, metronidazole, and doxycyclin followed by a 2-week treatment with moxifloxacin and a 2-month treatment with azithromycin.
Conclusion: In conclusion, these data suggest a specific clinical and microbiological approach in patients with humoral deficiency in order to detect H. bilis hepatobiliary diseases.
