The effects of patient and disease-related factors on the quality of life in patients with hypoparathyroidism.

Abstract

Hypoparathyroidism (HypoPT) is an orphan disease, which causes physical, emotional, and cognitive problems. We aimed to estimate the factors affecting the quality of life (QOL) of HypoPT patients. Basal characteristics, treatments, and laboratory results of the participants were recorded. QOL of the patients and controls were evaluated via the Short Form-36 (SF-36) survey. One hundred sixty HypoPT patients were compared with 148 controls. Patients had lower scores in all SF-36 domains than controls. Non-surgical patients had better scores in vitality and mental health compared with post-surgical ones. Males had higher scores in mental and physical health domains than females. Non-surgical patients had higher scores in mental health compared with post-surgical ones when calcium levels were between 8 and 8.9mg/dL. When we compared the patients with the pathological results, QOL scores of post-surgical patients with thyroid cancer were not different from the patients with thyroid nodular hyperplasia. HypoPT patients having an additional disease presented lower scores in physical functions and general health. Disease duration was found out positively correlated with vitality in non-surgical patients. While QOL is reduced in both post-surgical and non-surgical HypoPT groups, mental health seems to be less affected in non-surgical patients. Non-surgical patients might be tolerating hypocalcemia symptoms, lower calcium levels, and longer disease duration better than post-surgical ones. Having an additional disease affects the QOL negatively but having thyroid cancer may not change the QOL results of post-surgical patients.
