Overview
Atrophic glossitis is a condition characterized by inflammation and atrophy of the tongue epithelium, often associated with nutritional deficiencies, particularly of vitamin B12, iron, and folic acid 12.Diagnosis
Key Diagnostic Criteria: Presence of oral symptoms such as tongue swelling, discoloration (often erythematous or smooth), and discomfort 1.
Recommended Tests:
- Hemoglobin levels (Hb <13 g/dl in men, <12 g/dl in women)
- Serum iron levels (<60 μg/dl)
- Vitamin B12 levels (<200 pg/ml)
- Folic acid levels (<4 ng/ml)
- Serum homocysteine levels (elevated)
- Gastric parietal cell antibodies (GPCA) 2Management
First-Line Treatments:
- Supplementation with vitamin B complex (including B12) and deficient hematinics (iron if deficient) 1
Adjunctive Treatments:
- Address underlying deficiencies specifically (e.g., vitamin B12, iron, folic acid) 12Special Populations
Elderly: Higher prevalence of nutritional deficiencies; regular monitoring and supplementation recommended 2
Comorbidities: Presence of gastric parietal cell antibodies suggests autoimmune etiology; consider broader autoimmune workup 2Key Recommendations
Supplement with vitamin B complex and deficient hematinics to reduce elevated homocysteine levels (Evidence: Strong 1)
Screen for deficiencies in hemoglobin, iron, vitamin B12, and folic acid in patients with atrophic glossitis (Evidence: Strong 2)
Evaluate for gastric parietal cell antibodies in patients with atrophic glossitis to identify potential autoimmune associations (Evidence: Moderate 2)References
