Causes and Symptoms of PKU

Phenylketonuria, commonly known as PKU, is an inherited disorder caused by a genetic mutation. This mutation causes the body to be unable to break down an amino acid called phenylalanine properly. Phenylalanine comes from foods that contain protein. If left untreated, it can build up to high levels in the blood and cause intellectual disability and other neurological problems.

The most common symptoms of PKU include delayed development, unintelligible speech, lighter skin, eczema, and a "musty" body odor. If PKU goes undiagnosed and untreated, it can lead to serious intellectual disabilities, seizures, behavioral and psychiatric problems later in life. Early diagnosis through newborn screening allows for treatment to begin promptly to prevent disabilities.

Dietary Treatment for PKU

The primary Phenylketonuria Treatment involves following a lifelong diet that is very low in phenylalanine. This is known as the phenylalanine-restricted diet. It focuses on limiting foods high in protein from meat, fish, eggs, dairy, nuts, and beans. These foods are restricted or eliminated to reduce phenylalanine intake.

The PKU diet is made up of foods that are low in protein and specially formulated medical foods and formulas that provide protein in forms the body can use without producing excess phenylalanine. These medical foods and formulas contain amino acid replacements or synthetic proteins that lack phenylalanine. They come as powders, tablets, and liquids that are mixed into foods or consumed separately.

Strict adherence to the low-phenylalanine diet is critical for preventing complications. Dietary balance and supplements are also important to ensure the intake of other essential nutrients. A nutritionist can provide guidance on meal planning, recipes, and substitutes to help make the diet sustainable long-term. Monitoring blood phenylalanine levels regularly helps adjust the intake as needed as an individual grows.

Medication Options for Phenylketonuria Treatment

For some individuals with PKU, dietary treatment alone may not keep phenylalanine levels low enough. In these cases, medication can provide extra treatment beyond diet. The main medication options for PKU include:

- Sapropterin dihydrochloride (Kuvan): This medication helps some people with mild PKU metabolize phenylalanine better. It makes the restrictive diet less strict. Close monitoring is needed when using sapropterin.

- Pegvaliase-pqpz (Palynziq): This medication enables the body to break down phenylalanine in a different way for some with PKU. It must be used along with the low-phenylalanine diet. Side effects can include abdominal pain and vomiting.

- BH4 (biohagen hydrochloride): This is a newer investigational medication similar to sapropterin. Its long-term safety and effectiveness are still being evaluated.

- Gene therapy: Research into developing gene therapies that can permanently correct the genetic mutation causing PKU is underway. These hold promise but remain experimental.

Diet and medication treatment allows most individuals with PKU to live healthy lives if started early and adhered to properly under medical supervision. Optimizing phenylalanine control is key for normal development and preventing complications of the disorder.

Complimentary Therapies and Lifestyle Management in Phenylketonuria Treatment

Beyond core dietary and medical therapies, individuals with PKU may benefit from complementary approaches to treatment. These include monitoring stress levels and practicing relaxation techniques. Staying socially engaged and maintaining support networks can also help manage life with a chronic health condition.

Counseling may aid in acceptance of the diagnosis and build coping skills. Support groups can reduce feelings of isolation by connecting with others facing similar challenges. Transition plans from pediatric to adult healthcare are important for ensuring ongoing medical support. Care coordination between all specialists in biochemistry, nutrition, and behavior is also valuable. Lastly, regular physical activity is encouraged for overall wellness. With a comprehensive lifelong care approach, PKU can generally be successfully maintained.
