BACKGROUND Thalassemia is the most common inherited disease in southern China. However, this disorder is usually ignored by Jiangxi provincial health system and government due to lack of epidemiological data. MATERIALS AND METHODS A total of 9489 samples from Hakka Han and Gan-speaking Han in three geographical areas of Jiangxi Province were analyzed for both complete blood cell (CBC) count a...
The mechanism whereby deferoxamine (DF) inhibits the growth of malaria parasites was studied in rats infected with Plasmodium berghei. Peak parasitemia was 32.6% (day 14) in untreated controls and 0.15% (day 7) in rats receiving 0.33 mg/g in 8 hourly DF injections, subcutaneously. DF inhibition of parasite growth was achieved without any reduction in transferrin saturation or hemoglobin synthes...
Thalassaemia is a hereditary anaemia of widespread geographical distribution with marked variation in clinical severity. Morphological changes in the erythrocytes include microcytosis, anisopoikilocytosis, and the presence of target cells, while an increase in erythrocytic osmotic resistance is characteristic. The haemoglobin content of the erythrocytes is reduced and the present aetiological c...
We present a case of a 40-year-old female from Turkey, who was referred to our outpatient clinic for an undetermined thalassemia and sickle cell trait. At first consultation hemoglobin was decreased (71 g/L) with microcytosis (MCV 55.1 fL), and hypochromia (MCHC 239 g/L). The patient had severe iron deficiency. Brilliant cresyl blue staining showed >50% of the erythrocytes with typical Hemoglob...
BACKGROUND & OBJECTIVES In a routine community health survey conducted in adult Adivasis of the costal Maharashtra, microcytosis and hyprochromia were observed in more than 80 per cent of both males and females having normal haemoglobin levels suggesting the possibility of α-thalassaemia in these communities. We conducted a study in Adivasi students in the same region to find out the magnitude ...
The red cell distribution width (RDW) is an index of the variation in red cells size (anisocytosis). A study was conducted to examine the validity of using RDW in improving classification of microcytic anaemias. A total of 300 blood samples collected from a patient population aged 3 months to 55 years who were referred for haemoglobin electrophoresis were examined at the Aga Khan University Hos...
Iron metabolism in the Belgrade rat was examined in the intact animal and in the reticulocyte suspensions. The plasma iron turnover was increased. However, when allowance was made for the effect of the elevated plasma iron concentration, erythroid marrow capacity for iron uptake was at basal levels. Numbers of erythroid cells in marrow and spleen measured by the radioiron dilution technique wer...
Hemoglobin (Hb) D. Punjab [β121(GH4) Glu→Gln; HBB: C.364G>C] and β0-thalassemia 3.4 kb deletion are very rare in the Thai population. For the first time, the coinheritance of HbD-Punjab with β0-thalassemia 3.4 kb deletion was reported in a 7-year-old Thai girl. She had mild anemia (Hb 115.0 g/L and mean corpuscular hemoglobin 18.1 pg) with red blood cell microcytosis (mean corpuscular volume 52...
BACKGROUND Thalassemia major is one of the most common genetic disorders in Pakistan and over five thousand new patients are added in the pool annually. This familial disease has both medical and social implications, and therefore there is a need to assess the magnitude of beta-Thalassemia trait amongst family members of Thalassemia major patients. METHODS This cross-sectional descriptive stu...
BACKGROUND AND OBJECTIVE alpha-thalassemia is very common on all thalassemic geographical regions. The present work aimed at analyzing the relationship between the degree of microcytosis and hematological parameters and the type of alpha-thalassemic mutation. DESIGN AND METHODS Five hundred and thirty-six subjects with 4 kinds of alpha-thalassemia were examined using established techniques th...
