The Effect of Enzyme Replacement Therapy in Mucopolysaccharidosis
2021년 8월 7일 업데이트: Serkan Usgu, Hasan Kalyoncu University
Effects of Enzyme Replacement Therapy on Quality of Life, Functional Independence and Aerobic Capacity in Children With Mucopolysaccharidosis
Mucopolysaccharidosis (MPS) causes chronic, progressive systemic disorders due to enzyme deficiency.
Musculoskeletal manifestations of MPS include bone and vertebral deformities, restricted joint function and ROM (range of motion), rib cage abnormalities, short stature and hip dysplasia as well as flexion contracture in the knee and interphalangeal joints and joint laxity.
Currently, there is no treatment that cures the symptoms of MPS.
However, there are some forms of treatment that can delay the progression of the disease.
Enzyme replacement therapy is one such treatment and used for the management of some subtypes of MPS disease.
Enzyme replacement therapy (ERT) is based on the concept of replacing the missing enzyme in the circulation to prevent the build-up of glycosaminoglycan (GAG) in the tissues.
Very few studies in the literature have examined the impact of MPS in the lives of children affected by this disease.
Studies investigating functional capacity, independence and quality of life in children receiving or not receiving enzyme replacement therapy have not provided a clear picture of the problems faced by these children.
Secondly, psychological problems experienced by caregivers of children with MPS have not been studied specifically in former studies.
Therefore, the aim of this study was to examine the impact of ERT on aerobic capacity, functional independence and quality of life in children with MPS and to determine the anxiety and depression levels of their caregivers.

Pediatric Quality of Life Inventory
기간: 1 year
|
The Pediatric Quality of Life Inventory (PedsQL) is a health status instrument for the assessment of health-related quality of life in children and adolescents from 2 to 18 years of age.
The PedsQL can be completed by children themselves or with their parents.
The tool consists of a total of 23 questions that assess physical functioning (8 questions), emotional functioning (5 questions), social functioning (5 questions), and school functioning (5 questions).
Possible maximum scores range between 0 and 100 and higher scores indicate better quality of life.

Functional Independence Measure
기간: 1 year
|
Functional independence of the subjects was assessed using the Functional Independence Measure for Children (WeeFIM).
It is a short and validated tool to determine impairment of developmental, educational and social functioning in children with cerebral palsy and other developmental disorders.
The WeeFIM is an 18-item scale that measures the performance of the child in activities of daily living including bowel and bladder control, transfers, mobility, communication, eating, grooming, bathing, upper body dressing, lower body dressing, toileting and social cognition.
Each item is assigned a score between 1 and 7 points.
Higher total scores indicate greater level of independence.

Aerobic Capacity
기간: 1 year
|
Aerobic capacity was assessed using the 6-minute walk test (6MWT) and timed up and go (TUG) test. For the 6MWT test, the subjects were asked to walk but not run for 6 minutes on a 30-meter corridor as fast as possible. Care was taken not to change the pace. At the end of the test, total distance covered was measured. The TUG test is a practical test that allows quick assessment of dynamic balance, gait speed and mobility. During the test, the subjects were asked to stand up from a chair without holding on to the arms of the chair, walk 3 meters, turn, return to the chair without touching anything and sit down again. Total time was recorded in seconds. |

Balance
기간: 1 year
|
The modified functional reach test was developed by Lynch et al. to evaluate dynamic balance of the trunk.
It is a reliable and validated test to measure the distance an individual can reach forward without losing balance while sitting in a fixed position.
For the test, the subjects were instructed to sit with the arm kept parallel to the wall and shoulder flexed to 90 degrees and measurement was taken from the distal end the third metacarpal.

Depression Level
기간: 1 year
|
The Beck Depression Inventory (BDI) was used to determine the depression level of caregivers.
The BDI was developed for measure the risk of depression, the level of depressive symptoms and changes in the severity of depression in adults.
Reliability and validity of a Turkish version of the BDI were demonstrated by Hisli (1989).
The BDI is a 21-item, self-rated scale and each item is scored between 1 and 3 points.
Higher total scores indicate greater depression severity.

Anxiety Level
기간: 1 year

The Beck Anxiety Inventory (BAI) was used to evaluate the anxiety level of caregivers.
The BAI was developed for determine the frequency of anxiety symptoms experienced by individuals.
It is a 21-item, Likert scale with scores ranging from 0 and 3 points.
Higher overall scores denote greater level of anxiety.
Reliability and validity of a Turkish version of the BAI were demonstrated by Ulusoy et al. (1998).
