Mustard oil consumption and Harris platelet syndrome: unveiling a dietary link to thrombocytopenia in the Indian subcontinent

Abstract

Background and objectives: Asymptomatic thrombocytopenia, characterized by a reduced platelet count without bleeding symptoms, is notably prevalent in certain regions of India and Bangladesh, presenting a diagnostic challenge. A significant portion of healthy blood donors from Bangladesh and various parts of India, particularly West Bengal, exhibit this condition, termed Harris platelet syndrome (HPS). This review explores the potential correlation between mustard oil consumption, a common dietary staple in these regions, and the incidence of HPS. Methods: A comprehensive narrative review was conducted using systematic search strategies across databases such as Google Scholar, MEDLINE, PubMed, and Scopus. Keywords included "Harris platelet syndrome," "mustard oil consumption," "thrombocytopenia," and "erucic acid." Studies were selected based on relevance and quality, focusing on the epidemiology of HPS, dietary habits, and the thrombocytopenic effects of erucic acid. Results: HPS shows a significant geographical prevalence in the Indian subcontinent, notably in regions like West Bengal, Kashmir, and Assam. The review identifies a higher prevalence of thrombocytopenia in areas with predominant mustard oil usage. Studies highlight the association between dietary erucic acid from mustard oil and thrombocytopenia, with notable effects observed in patients treated with Lorenzo’s Oil, which contains erucic acid. Conclusions: The review highlights a significant association between mustard oil consumption and asymptomatic thrombocytopenia in the Indian subcontinent. The similarity in hematological profiles between HPS and erucic acid-induced thrombocytopenia underscores the need for further research. This includes measuring erucic acid levels in patients, conducting controlled dietary interventions, and genetic analyses to differentiate between genetic and environmental factors.
