In 2010, global anemia prevalence was 32.9%, that is, more than 2.2 billion people were affected. 1 The World Health Organization (WHO) defines anemia as a hemoglobin (Hb) count of less than 13 g/L in men, less than 12 g/L in nonpregnant women, and less than 11 g/L in pregnant women and the.

Tropical Sprue. Tropical sprue is a rare acquired disease, probably of infectious etiology, characterized by malabsorption and megaloblastic anemia. Diagnosis is clinical and by small-bowel biopsy. Treatment is with tetracycline and folate for 6 months [19,21] Both epoetin alfa and darbepoetin alfa are indicated for the treatment of anemia in patients with cancer who have nonmyeloid malignancies and anemia associated with chronic renal failure. Epoetin alfa carries additional indications for anemia in zidovudine-treated patients with HIV and reduction of transfusions in surgery patients •Mild anemia (Hb ≥9 g/dL): The Hb should rise at least 1 g/dL within four weeks of treatment •Moderate or severe anemia (Hb <9 g/dL): The Hb should rise at least 1 g/dL within the first two weeks of treatment •a reticulocyte response may be seen as soon as 72 hours after treatment initiation.

New York, McGraw-Hill Co, 1977, pp 356-362 Cotrimoxazole can also cause megaloblastic anemia because of folate antagonism, One plausible explanation for the reduction in anemia after initiation of treatment is that HAART can suppress HIV, a virus which is known to directly affect the bone marrow; UpToDate, Mitty J 2016 Megaloblastic anemia is a subset of macrocytic anemias that arises because of impaired nucleic acid synthesis in erythroid precursors. This impairment leads to ineffective RBC production and intramedullary hemolysis that is characterized by large cells with arrested nuclear maturation. The most common causes are vitamin B 12 and folic acid. Megaloblastic anemia due to vitamin B12 deficiency: Oral vitamin B12 1000 μg daily for 90 days vs. IM vitamin B12 1000 μg daily for 10 days, then once weekly for 28 days and after that continued with once monthly: Serum vitamin B12 levels increased in both groups at 90 days (oral group 213.8 pg/mL and IM group 225.5 pg/mL) Megaloblastic Anemia. Megaloblastic anemia is one form of macrocytic anemia in which red blood cells become enlarged and oval-shaped. It is caused by deficiencies of vitamin B12 (cobalamin) or folate. Numerous hematologic and neurologic abnormalities can result from the impaired DNA processes these deficiencies can cause

Vitamin B12 (cobalamin) is a water-soluble vitamin that is derived from animal products such as red meat, dairy, and eggs. Intrinsic factor is a glycoprotein that is produced by parietal cells in the stomach and necessary for the absorption of B12 in the terminal ileum. Once absorbed, B12 is used as a cofactor for enzymes that are involved in the synthesis of DNA, fatty acids, and myelin Transfusions are rarely required in patients with a megaloblastic anemia that is due to vitamin B12 deficiency. The likelihood of obtaining a dramatic response to cobalamin therapy within a few days of initiating treatment makes it unnecessary to subject the patient to the hazards of blood transfusion Treatment might include oxygen, pain relievers, and oral and intravenous fluids to reduce pain and prevent complications. Doctors might also recommend blood transfusions, folic acid supplements and antibiotics. A cancer drug called hydroxyurea (Droxia, Hydrea, Siklos) also is used to treat sickle cell anemia.

Clin Obstet Gynecol 1995; 38: 460 In our study, we came across 31 pediatric pancytopenic cases; again megaloblastic anemia was the common cause for pancytopenia, followed by aplastic anemia. Similar results were reported by Bhatnagar et al .[ 8 However, in a study by Gupta and colleagues, 105 patients aged 1.5 to 18 years, with a mean age of 8.6years, were included in the study Also, a complete blood count may show a megaloblastic anemia with elevated MCV (pernicious anemia). Treatment consists of replacing B 12, usually through injections. However, recent studies suggest that oral B 12 in high doses may be as beneficial as injections (Bolaman et al., 2003; Butler et al., 2006). Further studies are needed to clarify.

The hematological effect in both cases is the result of intracellular concentrations.

Treatment of tropical sprue with folic acid replacement was introduced more than 50 years ago and has become standard medical treatment. Vitamin B(12) replacement is usually added if there is evidence of B(12) deficiency or malabsorption. Treatment of tropical sprue with folate and B(12) cures the macrocytic anemia and the accompanying. The anemia of chronic disease is a multifactorial anemia.

The term pernicious anemia is an anachronism—it dates from the era when treatment had not yet been discovered, and the disease was fatal—but it remains in use for megaloblastic anemia resulting from vitamin B12 deficiency due to lack of intrinsic factor (IF).

Anemia: Overview. Anemia is a condition in which individuals have low Hb levels, which can arise from various causes. Anemia is accompanied by a reduced number of RBCs and may manifest with fatigue, shortness of breath, pallor, and weakness. Subtypes are classified by the size of RBCs, chronicity, and etiology Albai O, Timar B, Paun DL, Sima A, Roman D, Timar R.

Anemia may be common in the elderly patient, but it should not be accepted as normal aging. The scientific evidence suggests that consequences of untreated geriatric anemia are significant. Anemia leads to poorer quality of life and increased morbidity and mortality. Even mild anemia is more significant than traditionally thought by clinicians and is associated with increased hospitalizations.
