Abstract
BACKGROUND Drug-induced immune hemolytic anemia (DIIHA) is a rare condition that may result from the administration of an antibiotic, most notably the cephalosporin class, commonly used in both the adult and pediatric populations. A delay in recognition by a provider may lead to continuation of the offending agent and possibly result in fatal outcomes. CASE REPORT We report the case of a 65-year-old woman on ceftriaxone infusions after being diagnosed with acute mitral valve endocarditis 3 weeks prior, which presented with severe anemia and bilateral transient vision loss. Being a Jehovah's Witness, the patient refused blood product transfusions and was managed with alternative therapies. The etiology of the symptoms was suspected to be a hemolytic anemia directly related to her ceftriaxone infusions. CONCLUSIONS This report demonstrates the importance of close vigilance while prescribing drugs known to cause hemolytic anemia. Although rare, drug-induced immune hemolytic anemia caused by ceftriaxone may be a potentially fatal condition, but with early recognition and withdrawal of the offending agent, successful treatment may ensue. Serological tests should be utilized to obtain a definitive diagnosis.
