Recurrent Campylobacter Bacteremia as The First Manifestation of Hypogammaglobulinemia: A Case Report and Literature Review.
A 30-year-old woman with a past medical history of autoimmune hemolytic anemia presented with fever. Blood cultures grew Campylobacter. Her medical history was significant for four prior episodes of Campylobacter gastroenteritis and bacteremia. She received ciprofloxacin for the index presentation, then Meropenem de-escalated to doxycycline 6 months later following recurrence of Campylobacter. This prompted investigation for an immunodeficiency disorder. She was found to have hypogammaglobulinemia. Her Campylobacter infections resolved following the administration of intravenous immunoglobulins every 3 weeks. She did not have recurrence of Campylobacter during 5 years of follow-up. A literature search revealed an additional four case reports of six hypogammaglobulinemic adult individuals presenting with recurrent Campylobacter infections. Two patients were already on IVIG when Campylobacter infection occurred, and two patient achieved clinical cure following therapy with imipenem and IVIG. This case report highlights the importance of suspecting hypogammaglobulinemia in patients with recurrent Campylobacter infections, as this is sometimes the first manifestation of the condition.
