Pediculosis is a common condition caused by an infestation of head and body louse (ectoparasites) and remains a public health concern. Generally, infestation presents as pruritus in children and has a benign course, but there have been a handful of cases reported in the literature describing severe iron deficiency anemia (IDA) in high-risk groups such as children, history of psychiatric disorder including depression, and low socioeconomic status. Though an uncommonly encountered etiology of anemia, the aim of this case is to increase awareness of a rare cause of severe anemia from an ectoparasites affecting a high risk population, even in developed countries.

Zieve syndrome presents with a triad of hemolytic anemia, unexplained jaundice, and hyperlipidemia secondary to alcohol use/alcohol-induced liver injury, highlighting hemolytic anemia as the hallmark feature. Zieve syndrome is more common than originally perceived as its incidence is estimated to be 1 in 1600 admissions, but its mechanism is still poorly understood. This is a case of a 29-year-old man who developed Zieve syndrome shortly after admission for pancreatitis secondary to alcohol use disorder. Early diagnosis is important to reduce unnecessary tests and interventions. Further studies should be considered to evaluate the association between Zieve syndrome and pancreatitis.
