The effects of calcitonin on quality of life in hypothyroid patients – A pilot study

Abstract

Introduction: Hypothyroidism is a very common endocrine disorder routinely treated with levothyroxine replacement therapy. Despite treatment to biochemical euthyroidism, some individuals continue to have hypothyroidism-related symptoms. Many individuals with hypothyroidism also have low levels of calcitonin. Our aim was to evaluate the effects of calcitonin treatment on quality of life in hypothyroid individuals treated with levothyroxine. Methods: Adult, hypothyroid individuals were treated with nasal calcitonin spray, 200 international units daily for 6 weeks. Participants completed a modified City of Hope Quality of Life questionnaire prior to initiating calcitonin and after completing 6 weeks of therapy. Perception of quality-of-life benefit with calcitonin was also assessed. Results: Improvements in quality-of-life scores with calcitonin treatment from 184.77 to 148.44 (p = 0.342) were not statistically significant. Also, only one individual perceived any benefit with calcitonin therapy. Conclusion: Treatment with nasal calcitonin spray in individuals with hypothyroidism on levothyroxine replacement therapy did not result in quality-of-life benefit.
