Endoscopically diagnosed hookworm infestation in an adult with chronic iron deficiency anaemia

Abstract

Despite advances in hookworm control and prevention campaigns, the prevalence remains high in sub-Saharan Africa. Iron deficiency anaemia is a major complication in those with prolonged infection, a high hookworm burden, and undernutrition, though most infected people are asymptomatic. While infected patients are commonly diagnosed by the presence of ova or cysts in the stool, gastrointestinal (GI) endoscopy is required for those with negative stool tests and chronic iron deficiency anaemia. A 48-year-old female with symptoms of anaemia for nearly two years presented to Mbarara Regional Referral Hospital with worsening palpitations, easy fatigability, and dizziness over a period of one month. She was given blood transfusions on two occasions. She lives near the lake where she also gets water for drinking and domestic use. We advise GI endoscopy for all patients with chronic iron deficiency anaemia of unexplained aetiology on standard non-invasive testing. Hookworm’s mass empirical treatment policy in endemic areas should be further emphasised.
