Non-DS-AMKL has many clinical and laboratory features similar to and must be distinguished from Acute panmyelosis with myelofibrosis, a disorder characterized by bone marrow fibrosis, abnormal megakaryocytes, macrocytic erythropoiesis, defects in neutrophil production, reduced blood levels of most circulating cells (i.e. pancytopenia), and low levels of circulating blast cells. Analyses of circulating and bone marrow blast cells for features of AMKL (see Diagnosis section of DS-AMKL) and genetic aberrations is helpful in distinguishing the two diseases. Treatment
In a review of 153 patients treated for non-DS-AMKL between 1990 and 2014 with various intensive chemotherapy protocols that included cytarabine, an anthracycline (e.g. daunorubicin, doxorubicin), and in 25% of cases human stem cell transplantation, the probability of overall 4 year survival rate, probability of 4 year event-free survival, and probability of 4 year cumulative relapse rate were 56, 51, and 29%, respectively. A more recent treatment regimen that is similar to that used to treat DS-AMKL as described above (except it employs the high dose of cytarabine used to treat AML) gives better results and has been recommended for non-DS-AMKL. The response to this regimen approached that seen in non-DS-AMKL, i.e. its complete remission and estimated 10 year survival rates were both 76%. Similar to DS-AMKL treatment regimens, allogenic rather than autologous stem cell bone marrow transplantation should be considered in non-DS-AMKL cases that have relapsed following their first chemotherapy-induced complete remission.
Neonatal Hemochromatosis is a rare and severe liver disease of unknown origin, though research suggests that it may be alloimmune condition. Its characteristics are similar to hereditary hemochromatosis, where iron deposition causes damage to the liver and other organs and tissues. Causes
The causes of neonatal hemochromatosis are still unknown, but recent research has led to the hypothesis that it is an alloimmune disease. Evidence supporting this hypothesis includes the high rate among siblings (>80%). This evidence along with other research indicates that neonatal hemochromatosis could be classified as a congenital alloimmune hepatitis. Diagnosis
Differential diagnosis
The condition is sometimes confused with juvenile hemochromatosis, which is a hereditary hemochromatosis caused by mutations of a gene called hemojuvelin. While the symptoms and outcomes for these two diseases are similar, the causes appear to be different. Treatment
Effective treatment of the disease has been confined to liver transplants. Success has also been reported with an antioxidant chelation cocktail, though its effectiveness cannot be confirmed. Based on the alloimmune cause hypothesis, a new treatment involving high-dose immunoglobulin to pregnant mothers who have had a previous pregnancy with a confirmed neonatal hemochromatosis outcome, has provided very encouraging results.
