A Rare Case of Severe Folate Deficiency-Induced Pancytopenia.

Chronic alcoholism is a well-documented cause of folate deficiency, with past studies revealing high prevalence rates among alcoholics. Despite mandatory folate fortification in the UK from 2021, individuals with chronic alcohol consumption remain susceptible to severe folate deficiencies. This case study explores the hematological impact of severe folate deficiency in a 38-year-old female chronic alcoholic who presented with pancytopenia. The patient's symptoms included cough, shortness of breath, lethargy, reduced appetite, constipation, and rectal bleeding. Her medical history included polycystic ovarian syndrome and fatty liver disease. Blood tests revealed macrocytosis, pancytopenia, elevated bilirubin, and low serum folate levels. Management involved transfusions with packed red blood cells and oral folate supplementation, resulting in rapid hematological improvement. This case underscores the importance of early diagnosis and intervention for folate deficiency, particularly among chronic alcoholics. Folate, or vitamin B9, is essential for DNA synthesis and red blood cell production. Chronic alcohol consumption disrupts folate metabolism and absorption, leading to deficiencies. The patient's improvement with folate supplementation highlights the efficacy of this treatment. This case emphasizes the need for ongoing monitoring and support for chronic alcoholics to prevent recurrent folate deficiency. Further studies are necessary to assess the long-term efficacy of folate-fortification programs and ensure they meet the needs of vulnerable groups, including those with chronic alcohol dependence.
