Exploring the Journeys of Patients with Mucopolysaccharidosis Type VI and Their Family Members at a Tertiary Care Hospital in Saudi Arabia: A Mixed-Methods Case Study
This mixed-methods study of MPS-VI patients in Saudi Arabia demonstrates that while Enzyme Replacement Therapy significantly improves growth and functional endurance, families continue to face substantial challenges including diagnostic delays, treatment interruptions, logistical burdens, and psychosocial strain.

Imagine a body that slowly fills with a sticky, unusable substance, clogging the machinery of cells and causing bones to stiffen, hearts to struggle, and growth to stall. This is the reality for people living with Mucopolysaccharidosis type VI, a rare genetic condition where the body lacks a specific tool needed to break down complex sugars. Without this tool, the sugars build up inside tissues, leading to a progressive decline in health. While the condition affects the entire body, it leaves the mind sharp, meaning children with the disease are fully aware of their physical struggles. In Saudi Arabia, where families often marry within their extended kin, this rare disorder appears more frequently than in many other parts of the world, creating a unique challenge for the healthcare system to support these families.
Researchers at a major medical center in Riyadh set out to understand the full journey of these families, looking beyond just medical charts to see how the disease and its treatment play out in real life. They combined hard data from patient records with personal stories from parents and siblings. The study focused on nine children receiving a specific treatment called enzyme replacement therapy, which involves weekly infusions of a missing protein to help clear the buildup of sugars. By tracking these children over time and listening to their families, the team mapped the path from the first signs of illness to the long-term effects of treatment, revealing a story of medical hope shadowed by significant logistical and emotional hurdles.
The medical results showed that the treatment works. The children who received the infusions grew taller and gained weight, with the group growing an average of nearly 17 centimeters over the course of their treatment. Their ability to walk and move also improved; those who could walk a certain distance before treatment were able to walk about 75 meters further after receiving the therapy for a few years. The longer a child received the treatment, the more they seemed to benefit, suggesting that starting early and staying consistent is key. However, the researchers noted that while the children improved, they did not return to the physical norms of healthy children their age, indicating that some damage to the skeleton and body had already occurred before treatment began.
Despite these clear physical gains, the path to getting help was often long and confusing. On average, it took families about two years from the moment they first noticed something was wrong to finally receiving a confirmed diagnosis. During this time, parents described a frustrating cycle of visiting different doctors, receiving conflicting opinions, and being told their child had various other common illnesses. Many families felt they had to become their own experts, researching symptoms online and pushing for genetic tests just to get answers. This delay meant that children often started treatment later than they should have, missing out on the earliest possible window to prevent some of the physical decline.
Once a diagnosis was made, the journey did not become smooth; it became a test of endurance against a fragmented system. Even with a confirmed diagnosis, families faced delays in starting the treatment due to bureaucratic hurdles and the need for special approvals to import the medication. Once treatment began, it was not always uninterrupted. Families reported running into stock shortages at the hospital pharmacy, waiting hours for a dose to be prepared, or being told the medicine was unavailable on the day of their appointment. These interruptions were not just administrative annoyances; they caused physical pain for the children, who sometimes felt their symptoms return during breaks in therapy.
The burden of care fell heavily on the families, particularly those living outside the capital city. Because the specialized treatment was only available at one major hospital in Riyadh, parents had to travel long distances every week. This meant renting apartments in the city, taking time off work, and managing the stress of constant travel. For some, the hospital provided housing, but it was often too far from the clinic to be useful, forcing families to sleep in their cars or pay for their own lodging. The lack of a coordinated system meant that parents had to juggle separate appointments for different specialists, often on different days, turning a medical visit into a multi-day ordeal that drained their finances and energy.
Beyond the physical and logistical struggles, the emotional toll was profound. Parents described the shock of the diagnosis as a moment where their world stopped, followed by years of anxiety and grief. They watched their children struggle with pain, fatigue, and the feeling of being different from their peers. While many found strength in their faith, viewing their caregiving as a spiritual duty, they often lacked access to professional psychological support. The children themselves faced social stigma and bullying, leading some families to move to private schools or withdraw from community activities to protect them. The study highlighted that while the medical treatment addressed the biological disease, the system failed to address the human cost of living with it.
The researchers concluded that while the enzyme treatment is a powerful tool that helps children grow and move better, the system surrounding it is broken. The benefits of the medicine are being undermined by delays in diagnosis, inconsistent access to the drug, and a lack of support for the families who administer it. To truly help these children, the study suggests that Saudi Arabia needs to decentralize care, bringing specialized services closer to where families live, and streamline the processes that govern how treatment is approved and delivered. Most importantly, the healthcare system must recognize that caring for a child with a rare disease requires more than just medicine; it requires a coordinated network of logistical, educational, and emotional support that currently does not exist.
