To report the impact of an inpatient anticoagulation stewardship program at a community hospital to promote optimal anticoagulant use. The anticoagulation team (ACT) stewardship program consists of two clinical pharmacists and hematologists to provide oversight of anticoagulants, high cost reversal agents including prothrombin complex concentrate (PCC, Kcentra™), and heparin-induced thrombocytopenia (HIT) management. Intervention data and number of charts reviewed were collected.

Hereditary hemochromatosis is a common disorder of iron metabolism most frequently associated with mutations in the HFE gene. Hereditary hemochromatosis may be caused by other less common genetic mutations including those in the ferroportin gene. Whereas hereditary hemochromatosis associated with HFE mutations is an autosomal recessive disorder, essentially all cases of hereditary hemochromatosis associated with ferroportin mutations follow an autosomal dominant pattern of inheritance, and most cases are notable for the lack of an elevated transferrin saturation and presence of iron deposition in Kupffer cells.

Acute promyelocytic leukemia (APL) is the most curable subtype of AML yet it is not known to what extent newer therapies will succeed in the very elderly. Conventional chemotherapeutic induction regimens are usually too toxic for older patients, however, all trans-retinoic acid (ATRA) and arsenic trioxide (ATO) may be useful therapeutic options if used judiciously. This case series describes three octogenarians with APL all treated with ATRA and achieved complete remissions.

Article Synopsis
  • Two main mutations in the HFE gene, C282Y and H63D, are primarily responsible for hereditary hemochromatosis, affecting iron absorption in the body.
  • A study analyzed serum samples from nearly 5,000 patients to determine the frequency of these mutations and their clinical impact, revealing low rates of serious complications among homozygotes.
  • The research indicated that while C282Y homozygotes often show high transferrin saturation and serum ferritin levels, the presence of H63D mutations demonstrates modest biochemical impact and low clinical penetrance.
