Severe MPS II: A Challenging Condition
Severe MPS II, a condition predominantly found in young males, is characterized by limited concentration abilities and a significant discrepancy between physical capabilities and mental capacity. These children often struggle with toilet training, resulting in a continued reliance on diapers throughout their lives. Disciplinary measures may prove ineffective, as these children may demonstrate unresponsiveness. Aggressive outbursts are not uncommon.
Dietary restrictions are necessary for individuals with severe MPS II, and they often require assistance with feeding. Difficulties in chewing and swallowing pose a constant risk of choking. Consequently, food must be pureed or mashed to mitigate this hazard. As the mental capacity of these children diminishes, they may exhibit behaviors such as rocking, chewing on their fingers or clothing, and frequently dozing off. The reduced activity levels contribute to muscle mass and strength loss. Additionally, seizures and chest infections are frequent occurrences.
Unfortunately, the life expectancy for individuals with severe MPS II is often limited, with many not surviving past their mid-teens.
Treatment and Research
When it comes to Hunter syndrome, there is currently no known cure. However, medical professionals primarily concentrate on enhancing the child’s quality of life and slowing down the progression of the disease through treatment. Additionally, physicians may also address the underlying enzyme deficiency. In 2006, the FDA approved a drug for enzyme replacement therapy, which has proven to be beneficial in various ways. It has shown improvements in lung function, reduced liver size, and decreased GAG levels in the urine. Unfortunately, it does not have an impact on neurocognitive decline. To find alternative solutions, researchers are actively exploring different treatment options such as stem cell transplants. Furthermore, studies are being conducted on gene therapy with the aim of replacing the chromosome responsible for producing the IDS enzyme. However, researchers emphasize the need for further analysis in these areas.
