By ULFAR JONSSON, 0. STUART ROATH AND CHARLOTFE I. F. KIRKPATRICK BONE MARROW CHANGES suggestive or diagnostic of megaloblastic erythropoiesis have been recognized on a number of occasions in patients with hemolytic anemia. 4 ln many of these patients evalumation of a possible response to agents effective in megaloblastic anemias has not been possible because of concurrent transfusions or for o...

Deficiency of folate or vitamin B(12) (cobalamin) causes megaloblastic anemia, a disease characterized by pancytopenia due to the excessive apoptosis of hematopoietic progenitor cells. Clinical and experimental studies of megaloblastic anemia have demonstrated an impairment of DNA synthesis and repair in hematopoietic cells that is manifested by an increased percentage of cells in the DNA synth...

We present an eight-year-old boy who initially presented to us with megaloblastic anemia and subsequently developed dislocation of lens. The child had a positive sodium nitroprusside test and homocystinuria. He was diagnosed to have homocystinuria type 1. His anemia improved on oral pyridoxine and folic acid therapy. Homocystinuria should be remembered as a cause of megaloblastic anemia.

We prospectively studied 478 patients with megaloblastic anemia living in Tunisia. Overall, 98% of patients had vitamin B12 deficiency. Pernicious anemia accounted for most of these cases, and median age at presentation was 45 years. Megaloblastic anemia occurred in 19 subjects under 15 years of age, and of these, nine had the Immerslund-Graesbeck syndrome.

primary adrenal insufficiency (addison’s disease) is due to adrenocortical disease. this study is about a 40 year old man who had been referred to a hematologist who assessed him for anemia. he  had been affected by a periodic paresthesia one month prior to his visit to the physician. according to the clinical presentation, macrocytic anemia and hypersegmentation of pmn in pbs, bma/b was perfor...

Deficiency of vitamin B12 and/or folic acid as a cause of pyrexia, though known, is rarely reported in literature. We aimed to report a case in a 51 year old woman, who presented with fever and pancytopenia and was diagnosed to have megaloblastic anemia secondary to vitamin B12 and folate deficiency. The pyrexia subsided following the intramuscular injection of vitamin B12 and oral folic acid a...

Background: Megaloblastic anaemia is one of the frequently occurring diseases in a developing country such as India. anemia occurs mainly because vitamin B12 and folate deficiency. Proper clinical assessment megaloblastic very important for diagnosis treatment. Aim Objective: profile different age group, central Indian population. Material &Methods: A cross-sectional, observational study wa...

A nine years old boy presented with history of pallor and anaemia since early infancy along with neural hearing loss responding to empirical multivitamin and folic acid therapy started on basis of blood complete picture showing anaemia and megaloblastic anaemia. On investigation he was diagnosed with Thiamine Responsive Megaloblastic Anaemia, a very rare condition in our settings.

The incidence of megaloblastic anaemia in pregnancy and the puerperium in north Staffordshire has steadily declined as a result of prophylaxis with folic acid. In the presence of advanced folic acid deficiency and with a florid megaloblastic marrow, the anaemia is usually severe, but in many patients the disease is relatively mild and the degree of anaemia is determined more by blood loss or as...

The pathogenesis of many of the common forms of megaloblastic anaemia in malnourished populations is obscure. The aetiological factors and response to therapy vary in different geographical areas, and confusion has arisen by the retention of certain ambiguous terms. Thus "nutritional megaloblastic anaemia" is often really megaloblastic anaemia associated with pregnancy, and "tropical megaloblas...
