Methylmalonic Acidemia and Megaloblastic Anemia due to Congenital Intrinsic Factor Deficiency
Causes of vitamin B12 deficiency in children include decreased intake, abnormal absorption, and inborn errors of B12 transport and metabolism. Rare causes of abnormal cobalamin absorption include Imerslund-Grasbeck syndrome (IGS) and intrinsic factor deficiency (IFD). IGS and IFD are caused by defects in the genes CUBN, AMN, and GIF. We describe a 2 year old male who presented with severe megaloblastic anemia and methylmalonic acidemia. He was found to have a GIF heterozygous mutation c.79+1G>A associated with congenital gastric intrinsic factor deficiency and a novel variant c.960C>A in trans position.
Descriptive Study of Exposure to Inhalation Zanamivir and Pregnancy-Related Outcomes
The Health Improvement Network (THIN) provided data from UK General Practitioners (GPs) for 144 pregnant women who were prescribed zanamivir and 144 age- and date-matched untreated comparators with no recorded diagnosis of influenza. Groups were assessed for baseline characteristics, treatment-emergent diagnoses in the mother, pregnancy outcomes and congenital malformations diagnosed in the offspring within 28 days of birth.
