Johanson-Blizzard syndrome



My younger son has Johanson Blizzard syndrome. He has arrested growth, hearing loss, some teeth disappearance and pancreatic insufficiency. He was also diagnosed with pure red cell aplasia. How can we help pancreatic insufficiency, which helps with growth? Is there any help for hearing impairment?

The treatment of Johanson-Blizzard syndrome focuses on the specific symptoms that are present in each individual. Those with pancreatic insufficiency may require pancreatic enzyme supplements (e.g., oral pancreatin) to promote proper absorption of fats and other necessary nutrients. Vitamin supplements may also be needed to prevent or treat vitamin deficiencies that may result from malabsorption due to pancreatic insufficiency. A special diet with easily-absorbed, high-protein supplements may also be prescribed to ensure that total nutritional requirements are met. Although these therapies usually lead to improved nutrient absorption and weight gain, most affected children still remain smaller and shorter than average for their ages. A surgery for pancreas removal (pancreatectomy) and with islet autotransplantation (TPIAT) should be used only as a last resort for patients with severe symptoms of pancreatitis.[1]
 
Individuals with hypothyroidism may need thyroxine hormone replacement therapy. Other abnormalities such as craniofacial, genitourinary, cardiac, and/or other malformations associated with the condition may be treated with surgery. Dental abnormalities may be treated with bonding agents, use of dentures, and/or other techniques. Hearing loss may be treated with hearing aids. Early intervention is important to ensure that children with JBS reach their full potential. Affected children may benefit from special remedial education, special social support, and other medical, social, and/or vocational services.[1]
