What Causes CSID? Will You Outgrow CSID?

Certain mutations in the sucrase-isomaltase gene (SI) cause Congenital Sucrase-Isomaltase Deficiency (CSID). The SI gene provides genetic instructions to the cells for producing the sucrase-isomaltase enzymes. These enzymes are found in the brush border of the small intestine and are responsible for breaking down sucrose and maltose into their simple sugar components. Once these simple sugars are broken down, they are absorbed by the small intestine and into the bloodstream.

Genetic mutations that cause CSID do so by providing genetic instructions that alter the sucrase-isomaltase enzyme structure, disrupt production of the enzyme, or impair the functioning of the enzyme. These changes prevent the enzyme from breaking down sucrose and maltose, causing the gastrointestinal symptoms associated with CSID.

CSID is a rare, inherited disorder that is not outgrown, although some factors may mitigate the gastrointestinal symptoms over time. Congenital means “present at birth,” and the enzyme deficiency is not acquired due to infection or other external influence. Proper sucrose digestion requires production of new sucrase-isomaltase enzymes each time food is consumed. Those with CSID lack the ability to produce sucrase-isomaltase, so CSID is a chronic disorder that will never be outgrown.

IMPORTANT SAFETY INFORMATION FOR SUCRAID^® (SACROSIDASE) ORAL SOLUTION

Sucraid^® may cause a serious allergic reaction. If you notice any swelling or have difficulty breathing, get emergency help right away.
Tell your doctor if you are allergic to, have ever had a reaction to, or have ever had difficulty taking yeast, yeast products, papain, or glycerin (glycerol).
Sucraid^® does not break down some sugars that come from the digestion of starch. You may need to restrict the amount of starch in your diet. Your doctor will tell you if you should restrict starch in your diet.
Tell your doctor if you have diabetes, as your blood glucose levels may change if you begin taking Sucraid^®. Your doctor will tell you if your diet or diabetes medicines need to be changed.
Some patients treated with Sucraid^® may have worse abdominal pain, vomiting, nausea, or diarrhea. Constipation, difficulty sleeping, headache, nervousness, and dehydration have also occurred in patients treated with Sucraid^®. Check with your doctor if you notice these or other side effects.
Sucraid^® has not been tested to see if it works in patients with secondary (acquired) sucrase deficiency.
NEVER HEAT SUCRAID OR PUT IT IN WARM OR HOT BEVERAGES OR INFANT FORMULA. Do not mix Sucraid^® with fruit juice or take it with fruit juice. Take Sucraid® as prescribed by your doctor. Normally, half of the dose of Sucraid^® is taken before a meal or snack and the other half is taken during the meal or snack.
Sucraid^® should be refrigerated at 36°F-46°F (2°C-8°C) and should be protected from heat and light.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.FDA.gov/medwatch or call 1-800-FDA-1088.
