Bloom Syndrome (Congenital Telangiectatic Erythema) Follow-up
- Author: Amira M Elbendary, MBBCh, MSc; Chief Editor: Dirk M Elston, MD more...
Men with Bloom syndrome (congenital telangiectatic erythema) are sterile; women have reduced fertility and a shortened reproductive span.
Recurrent respiratory and gastrointestinal tract infections and the development of chronic lung disease are additional complications, as is the early development of different types of cancers at any site.
Increased risk of premature death in the second or third decade occurs secondary to malignancies. Patients with Bloom syndrome (congenital telangiectatic erythema) are estimated to develop malignancy at a rate 150-300 times higher than the general population. Twenty percent of Bloom syndrome patients develop malignancy during their life time. Various types of leukemia develop at a mean age of 22 years. Patients who survive beyond age 22 years develop solid tumors at an average age of 35 years. Fortunately, these tumors are sensitive to chemotherapy and radiotherapy.
Early diagnosis of leukemia is, at present, not known to improve the chances of curative therapy. Frequent hematologic examinations in children are not advised for fear of untoward psychologic effects. Allogeneic marrow grafting has not been performed in Bloom syndrome patients. Men with Bloom syndrome are sterile; women have reduced fertility and a shortened reproductive span. Bloom syndrome patients who become pregnant are at high risk for premature delivery. Intelligence is usually normal, although mild deficiency has occurred in a few affected persons. Diabetes occurs in approximately 10% of individuals with Bloom syndrome.
Resistance to infections gradually improves with age, as do erythema and photosensitivity.
