9 - IMPACT OF CHRONIC HYPOPARATHYROIDISM ON HEALTH-RELATED QUALITY OF LIFE: FINDINGS FROM A 13-COUNTRY PATIENT SURVEY

Thursday, Apr 25
12:30 PM – 1:00 PM

Objective :

Significant knowledge gaps exist regarding the humanistic effects of hypoparathyroidism (HypoPT), a rare debilitating disorder. We report results from a global survey (13 countries) to characterize the impact of HypoPT on health-related quality of life (HRQoL) from the patient (pt) perspective.


Methods :

An anonymous survey was conducted in pts with uncontrolled chronic HypoPT (as determined by pts’ report of persistent symptoms and/or poorly controlled calcium levels as told by their physician) despite receiving conventional therapy. Pts currently or previously treated with parathyroid hormone were excluded. HRQoL and health status were evaluated using 2 validated instruments, 36-item short form health survey (SF-36) and 5-level EuroQoL 5 dimensions (EQ-5D-5L). HypoPT-associated symptoms were assessed through a disease-specific Hypoparathyroidism Symptom Diary. All analyses were descriptive.


Results :

Survey was conducted Oct 2017─Mar 2018 in 398 pts who met the study inclusion criteria (mean age, 51.7 years; women, 78%; surgery as main cause of HypoPT, 80%; mean duration of HypoPT, 8.9 years). Per Hypoparathyroidism Symptom Diary, pts reported symptoms of physical fatigue (97%), muscle cramps (86%), tingling (84%) and heaviness in limbs (82%), and cognitive and mood symptoms of brain fog (77%), anxiety (78%), and depression (76%). There was an inverse relationship between HypoPT symptom severity and both HRQoL assessment scores – the greater the severity, the lower the HRQoL and health status scores. Mean EQ-5D-5L utility scores (0–1) were 0.9/0.8/0.7/0.4 for pts reporting no/mild/moderate/severe HypoPT symptoms, respectively. EQ-5D-5L visual analog scale scores (0–100) were 86.9/72.5/57.7/41.1 for pts reporting no/mild/moderate/severe HypoPT symptoms, respectively. Mean SF-36 summary scores (0‒100) were 45.4/44.6/37.1/28.7 (physical component summary [PCS]) and 53.2/44.9/35.2/31.6 (mental health component summary [MCS]) for pts reporting no/mild/moderate/severe HypoPT symptoms, respectively.


Discussion :

Uncontrolled chronic HypoPT can be associated with substantial burdensome symptoms. The degree of HRQoL reduction corresponds with the magnitude of HypoPT-related symptom severity reported by pts. Mean SF-36 PCS and MCS scores for pts with chronic HypoPT in this survey were lower than scores reported in literature for pts with other disease states, including heart disease, hematologic disorders, pituitary disorders, diabetes, and cancer.


Conclusion :

Findings showed that despite receiving conventional treatment, chronic HypoPT was associated with burdensome symptoms  and negative impact on HRQoL.

Today’s Medical Profession in the Pharmaceutical Industry is naturally positioned to play an expanded role along the full drug value chain, straddling the Research & Development and the Marketing sides of Pharma. In line with this concept - particularly relevant for rare diseases – I have covered a variety of medical tasks across functions as detailed below: I have been in clinical practice as MD with specialization in cardiology for some years and then I have joined Pharma Industry Companies initially as Medical Director in Italy, then covering global positions in R&D, Strategic Marketing and Medical Affairs for over 25 years, with focus on imaging diagnostics and on rare diseases. Also conversant with the discovery and the preclinical phases of drug development in addition to the post-Market authorization phases of drug development, in 2004 I was honored by the American College of Cardiology with the fellowship for outstanding contributions to the cardiovascular field. Owner of three patents on new methods for diagnostic imaging in heart failure, I am author of >50 publications in peer review journals.
