Pediatric Metabolic Disease

What is Pediatric Metabolic Disease?

The Metabolic Clinic consists of a multidisciplinary team dedicated to providing care to children with known or suspected inborn errors of metabolism. The clinic provides diagnostic evaluations of children, from birth to 18 years old, in whom a metabolic disorder is considered. Therapeutic management is provided for children with diagnosed inborn errors of metabolism, age’s birth to 21 years. We work closely with parents and families to provide treatment and support to improve clinical outcomes.

The Texas State Department of Health (TDSH) screens approximately 400,000 newborns annually for inherited metabolic diseases and other conditions. Babies who have abnormal newborn screens and go on to be diagnosed with an inborn error of metabolism receive follow up and long term care in the Metabolic Clinic. For more information on the newborn screening diagnostic process, please see Newborn Screening.

The Metabolism Clinic physicians are available for inpatient and outpatient consultations for physicians with diagnostic or management concerns related to metabolic diseases.

How is Pediatric Metabolic Disease diagnosed?

Diagnostic Evaluation of Patients with Suspected Metabolic Disease

The Metabolic Clinic staff evaluates patients with a history concerning for a metabolic disease. The evaluation process includes review of clinical and laboratory findings, plus family history information. Recommendations for additional testing and evaluation are provided.

Diagnosis and ongoing care of patient with lysosomal storage disorders

The Metabolic Clinic provides diagnosis, management, treatment, genetic counseling, and education for lysosomal storage disorders. This includes Gaucher disease, Fabry disease, and mucopolysaccharidoses (MPS disorders) such as Hurler, Sanfilippo and Morquio syndromes. We coordinate clinically available enzyme replacement therapy for these conditions. Children’s Health Special Procedures Clinic nurses provide weekly or biweekly enzyme replacement with oversight of the metabolic physicians.

Ongoing Care of Patients with Inborn Errors of Metabolism

The Metabolic Clinic consists of a team of specialists dedicated to working with families to provide on-going management recommendations and support for treatment of inborn errors of metabolism. This team includes metabolic physicians, genetic counselors, a metabolic dietitian and a metabolic social worker.

We participate in the annual family camp, Camp PHEnomenal, for children on low protein diets, primarily PKU. Ask the clinic staff for more information regarding this year’s camp.

How is Pediatric Metabolic Disease treated?

Dietary Management

An individualized plan of dietary treatment is developed for each patient who has a confirmed diagnosis that is managed by diet. This includes disorders of amino acids, organic acids, and carbohydrate metabolism. The dietitian evaluates the patient's current nutritional status, obtaining nutrition history from patients and parents, and develops dietary treatment plans by correlating blood levels with intake of target nutrients. We also provide diet teaching and resources to assist in managing your child’s special diet.

Genetic Counseling

The Metabolic Clinic provides genetic counseling and education related to inborn errors of metabolism. This may include an explanation of the patient's diagnosis, mode of inheritance, chance of recurrence in future children or grandchildren, and information regarding prenatal diagnosis if applicable.
