Staphylococcus aureus causes most liver abscesses in patients with CGD. Often the liver abscesses are hard to drain and may need surgery. [primaryimmune.org]

Treatment
Early diagnosis and treatment during infancy can improve prognosis; however, liver cirrhosis can still impact life expectancy. Treatment Treatment for CDG Type 1B involves life-long management with high doses of oral mannose therapy. [evolvegene.com]
Treatment options are being explored to facilitate glycosylation with either a membrane-permeable mannose-1-phosphate treatment or enzyme replacement therapy. [digitalcommons.hsc.unt.edu]
