ABSTRACT

Objective:

COVID-19 pandemic was associated with increased risk of hypovitaminosis D due to lockdown regulations and limited outdoor activities, while young adult patients with autoimmune conditions may associated decreased values of 25-hydroxyvitamin D due to copresence of celiac disease, glucocorticoid exposure, malabsorption, overtreatment of autoimmune hypothyroidism, etc. (1-5).We aim to introduce a female case known with autoimmune conditions who was admitted for vitaminD deficiency related symptoms during pandemic. Case report A 41-year-old, nonsmoker female is admitted for nonspecific muscle cramps, and joints pain, asthenia which is persistent for the last several months in addition to chronic low back pain (which required chronic use of nonsteroid anti-inflammatory medication). Her personal medical background reveals a diagnosis of HLA-B27-positive ankylosing spondylitis that was established seven years before current admission. She is also known with autoimmune thyroiditis with negative antibodies, a diagnostic that was based on suggestive ultrasound features with highly hypoechoic pattern of relative small thyroid gland (and normal thyroid function). She is also confirmed with thrombophilia. She has a negative personal history of confirmed COVID-19 infection and she followed the lockdown restrictions for several weeks. The family medical history is irrelevant. On admission, clinical examination of the thyroid is within normal limits on amenstruated normal weighted female. Biochemistry data points out normal total calcium of 9.45 mg/dL (normal 8.4-10.3 mg/dL). Endocrine panel shows TSH=1.28 μUI/mL (normal 0.5-4.5 μUI/mL), free levothyroxine=11.65 pmol/L (normal 9-19 pmol/L), anti-thyroperoxidase antibodies=10.88 UI/mL (normal 0-35), anti-thyroglobulin antibodies=10 UI/mL (normal 0-115 UI/mL). 25-hydroxyvitamin D=10 ng/mL (normal >30 ng/mL) with increased PTH levels and negative antibodies for celiac disease. Supplementation with daily 2000 UI of vitamin D for 12 weeks followed by daily 1000 UI was recommended.

Conclusion:

The association thrombophilia-hypovitaminosis D has been reported in some patients, but it is rather incidental. Chronic use of antiinflammatory medication may cause malabsorption, and also the potential of a second autoimmune disease at intestinal level may cause this deficiency, but the current pandemic reality has become a new cause of it.
