ACUTE FOLIC ACID DEFICIENCY OF UNKNOWN AETIOLOGY: TEMPERATE SPRUE

Area of Science:

• Gastroenterology
• Hematology
• Internal Medicine

Background:

• Idiopathic steatorrhea encompasses various conditions causing fat malabsorption.
• Diarrhea is a common symptom, but not always present in malabsorption syndromes.
• Folic acid deficiency leading to megaloblastic anemia indicates significant nutrient malabsorption.

Purpose of the Study:

• To investigate a potential homogeneous group of patients presenting with specific symptoms.
• To differentiate this group from typical idiopathic steatorrhea cases.
• To propose a novel diagnostic label for this patient cohort.

Main Methods:

• Retrospective analysis of 20 patient cases.
• Clinical history review focusing on symptoms and duration.
• Laboratory evaluation for nutritional deficiencies, specifically folic acid.

Main Results:

• Patients presented with megaloblastic anemia due to folic acid deficiency.
• Short patient histories were noted.
• Diarrhea was not a predominant feature in this cohort.
• These findings suggest a distinct clinical entity.

Conclusions:

• The identified patient group may represent a homogeneous syndrome.
• The proposed diagnostic label is 'temperate sprue'.
• This classification aids in differentiating from idiopathic steatorrhea when diarrhea is absent.
