Clinico-laboratory Profile and Outcomes of Megaloblastic Anemia presenting as Severe Pyrexial Illness mimicking Tropical Infection.

BACKGROUND: Anemia-causing fever has been described in patients with megaloblastic anemia. Although the exact mechanism of this is unknown, high-grade fever is relatively less reported. MATERIALS AND METHODS: This prospective observational study included all new cases of megaloblastic anemia presenting with febrile illness (>101°F) during a 3-year period. Patients with existing anemia, comorbidities, and other causes of macrocytosis were excluded. A detailed evaluation for megaloblastic anemia and workup for excluding tropical infections was done. The patients were treated with parenteral vitamin B12, folic acid, and other hematinics. RESULTS: Around 24 cases of megaloblastic anemia presenting with high-grade fever were included, with 14 (58.3%) males, mean duration of fever 7.7 days (4-18 days), and 09 (37.5%) having temperature >103°F. The mean hemoglobin (Hb) was 8.15 g/dL (3.7-11.1 g/dL), the mean corpuscular volume (MCV) was 111 ± 7.8 fL, 18 (75%) had unconjugated hyperbilirubinemia, the mean lactate dehydrogenase (LDH) was 814 ± 24 IU/L, and 21 (87.5%) had low B12 or folate levels. Most showed good therapeutic response to B12 or folic acid with defervescence in 1-5 days (mean 2.6 days) and improvement in lab parameters in 1 week. The study population was divided into those with temperature ≥103°F, and temperature <103°F it was seen that there was a significant association (p < 0.05) with leucocyte count of ≤3000/cumm, and MCV ≥110 fL, in patients with temperature ≥103°F Conclusion: Megaloblastic anemia should be considered in the differentials of a patient presenting with a febrile illness with no clinical localization and a negative initial fever workup. Early identification and prompt therapy of this easily treatable disorder are very essential.

Human C-terminal CUBN variants associate with chronic proteinuria and normal renal function.

BACKGROUNDProteinuria is considered an unfavorable clinical condition that accelerates renal and cardiovascular disease. However, it is not clear whether all forms of proteinuria are damaging. Mutations in CUBN cause Imerslund-Gräsbeck syndrome (IGS), which is characterized by intestinal malabsorption of vitamin B12 and in some cases proteinuria. CUBN encodes for cubilin, an intestinal and proximal tubular uptake receptor containing 27 CUB domains for ligand binding.METHODSWe used next-generation sequencing for renal disease genes to genotype cohorts of patients with suspected hereditary renal disease and chronic proteinuria. CUBN variants were analyzed using bioinformatics, structural modeling, and epidemiological methods.RESULTSWe identified 39 patients, in whom biallelic pathogenic variants in the CUBN gene were associated with chronic isolated proteinuria and early childhood onset. Since the proteinuria in these patients had a high proportion of albuminuria, glomerular diseases such as steroid-resistant nephrotic syndrome or Alport syndrome were often the primary clinical diagnosis, motivating renal biopsies and the use of proteinuria-lowering treatments. However, renal function was normal in all cases. By contrast, we did not found any biallelic CUBN variants in proteinuric patients with reduced renal function or focal segmental glomerulosclerosis. Unlike the more N-terminal IGS mutations, 37 of the 41 proteinuria-associated CUBN variants led to modifications or truncations after the vitamin B12-binding domain. Finally, we show that 4 C-terminal CUBN variants are associated with albuminuria and slightly increased GFR in meta-analyses of large population-based cohorts.CONCLUSIONCollectively, our data suggest an important role for the C-terminal half of cubilin in renal albumin reabsorption. Albuminuria due to reduced cubilin function could be an unexpectedly common benign condition in humans that may not require any proteinuria-lowering treatment or renal biopsy.FUNDINGATIP-Avenir program, Fondation Bettencourt-Schueller (Liliane Bettencourt Chair of Developmental Biology), Agence Nationale de la Recherche (ANR) Investissements d'avenir program (ANR-10-IAHU-01) and NEPHROFLY (ANR-14-ACHN-0013, to MS), Steno Collaborative Grant 2018 (NNF18OC0052457, to TSA and MS), Heisenberg Professorship of the German Research Foundation (KO 3598/5-1, to AK), Deutsche Forschungsgemeinschaft (DFG) Collaborative Research Centre (SFB) KIDGEM 1140 (project 246781735, to CB), and Federal Ministry of Education and Research (BMB) (01GM1515C, to CB).

Odaman-Al I, Gezdirici A, Yildiz M, Ersoy G, Aydogan G, Salcioglu Z, Tahtakesen TN, Önal H, Küçükemre-Aydin B. A novel mutation in the SLC19A2 gene in a Turkish male with thiamine-responsive megaloblastic anemia syndrome. Turk J Pediatr 2019; 61: 257-260. Thiamine-responsive megaloblastic anemia (TRMA) is a very rare syndrome characterized by the triad of early onset megaloblastic anemia, sensorineural deafness and diabetes mellitus. Here we report, a 5-year-old boy who presented with transfusion dependent anemia and diabetes mellitus and was diagnosed with TRMA. Besides reporting a novel mutation of the causative gene SLC19A2, we wanted to emphasize this syndrome in the aspect of coexistence of insulin dependent diabetes, transfusion dependent anemia and thrombocytopenia.

[Etiological profile of anemia in a department of internal medicine]. / Profil étiologique des anémies dans un service de médecine interne.

Anemia is a major public health problem worldwide despite remarkable improvement in living conditions. The World Health Organization (WHO) classifies it as one of the ten most serious problems in the world. This study aims to describe the epidemiologic and etiologic profiles of the cases of anemia treated during our training. We conducted a retrospective study involving 150 patients carried out over 5 years, from January 2011 to December 2015. The average age of our patients was 48.8 years and women were more likely to be affected than men, with a sex ratio of 1.78. The mean hemoglobin was 8 g/dl, ranging from 3.4 to 11.4 g/dl. Iron deficiency anemia was the leading etiologic diagnosis made in 60% of cases, followed by megaloblastic anemia in 21% of patients and haemolytic anemia in 7.33% of cases. The occurrence of anemia in adults may represent a real diagnostic challenge for the internist as it is sometimes associated with an emergency context. Specialized examinations may be necessary.

Iron deficiency anemia and megaloblastic anemia in obese patients.

BACKGROUND: The association between obesity and different types of anemia remained uncertain. The present study aimed to assess the relation between obesity parameters and the occurrence of iron deficiency anemia and also megaloblastic anemia among Iranian population. METHODS AND MATERIALS: This cross-sectional study was performed on 1252 patients with morbid obesity that randomly selected from all patients referred to Clinic of obesity at Rasoul-e-Akram Hospital in 2014. The morbid obesity was defined according to the guideline as body mass index (BMI) equal to or higher than 40 kg/m2. Various laboratory parameters including serum levels of hemoglobin, iron, ferritin, folic acid, and vitamin B12 were assessed using the standard laboratory techniques. RESULTS: BMI was adversely associated with serum vitamin B12, but not associated with other hematologic parameters. The overall prevalence of iron deficiency anemia was 9.8%. The prevalence of iron deficiency anemia was independent to patients' age and also to body mass index. The prevalence of vitamin B12 deficiency was totally 20.9%. According to the multivariable logistic regression model, no association was revealed between BMI and the occurrence of iron deficiency anemia adjusting gender and age. A similar regression model showed that higher BMI could predict occurrence of vitamin B12 deficiency in morbid obese patients. CONCLUSION: Although iron deficiency is a common finding among obese patients, vitamin B12 deficiency is more frequent so about one-fifth of these patients suffer vitamin B12 deficiency. In fact, the exacerbation of obesity can result in exacerbation of vitamin B12 deficiency.

Hematologic features among anemic Cameroonian pregnant women: a cross sectional study.

INTRODUCTION: Iron deficiency anemia is the leading cause of anemia worldwide. It may also be the leading cause of anemia in pregnancy, although this has not yet been demonstrated in our country. The aim of the study was to describe hematologic features of Cameroonian anemic pregnant women. METHODS: This cross sectional analytical study was carried out in the maternity of the Yaoundé University Teaching Hospital, Cameroon, from March 1(st), 2011 to February 28(th), 2013. Two hundred women with singleton pregnancies and Hb concentration at booking <10 g/dl were recruited. Main variables recorded were maternal age, parity, marital status, gestational age, Hb concentration, blood group, Hb electrophoresis, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), pack cell volume (PCV). Data were analyzed using SPSS 18.0. P<0.05 was considered statistically significant. RESULTS: Figures for 110 women (55%) showed microcytosis, hypochromia was observed in 122 (61%) women and megaloblastic anemia in eight women (4%). Thrombopenia was observed in 16 women (8%) and thrombocytosis in six women (3%). Anemia was microcytic hypochromic in 110 women (55%), megaloblastic in eight women (4%), normocytic hypochromic in 12 women (6%), and normocytic normochromic in 70 women (35%). CONCLUSION: Hematologic features of Cameroonian anemic pregnant women showed that although iron deficiency anemia is the leading cause of anemia, megaloblastic anemia is also present in our environment. A normal hematologic feature in more than the third of women shows that the cause of anemia is not always nutritional.

Anemia in severe acute malnutrition.

OBJECTIVES: India has the highest prevalence of severe acute malnutrition (SAM). Severe anemia is one of the comorbidities responsible for increased mortality in severely malnourished children, yet it has not received the attention it should. The aim of the present study was to determine the prevalence and type of anemia and to evaluate the possible etiologies for severe anemia, in these children. METHODS: A cross-sectional study of patients with SAM in a tertiary care hospital in northern India over a period of 12 mo from Sept. 1, 2010 to Aug. 31, 2011 was conducted. We observed the prevalence of severe anemia (hemoglobin < 7 g/dL), morphologic type of anemia, number of patients requiring blood transfusion, hematologic profile of mothers, nature of feeding, duration of exclusive breastfeeding, and the demographic profile of these patients. RESULTS: Included in the study were 131 cases of SAM. The age group varied between 6 and to 59 mo. Of patients with SAM, 67.3% had severe anemia; 13.8% had moderate anemia. Of these patients, 25% required packed red blood cell transfusion. The most common type of anemia was microcytic (38.6%) followed by megaloblastic (30.5%). CONCLUSIONS: A high incidence of severe anemia in SAM with a large proportion (25%) requiring blood transfusion is a pointer toward nutritional anemia being a very common comorbidity of SAM requiring hospital admission. Because megaloblastic anemia closely followed microcytic anemia, supplementation with vitamin B12 in addition to iron and folic acid would be recommended.

Anemia after gastrectomy for early gastric cancer: long-term follow-up observational study.

AIM: To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer. METHODS: The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed. Patients with anemia in the preoperative workup, cancer recurrence, undergoing systemic chemotherapy, with other medical conditions that can cause anemia, or treated during follow up with red cell transfusions or supplements for anemia were excluded. Anemia was defined by World Health Organization criteria (Hb < 12 g/dL in women and < 13 g/dL in men). Iron deficiency was defined as serum ferritin < 20 µg/dL. Vitamin B12 deficiency was defined as serum vitamin B12 < 200 pg/mL. Iron deficiency anemia was defined as anemia with concomitant iron deficiency. Anemia from vitamin B12 deficiency was defined as megaloblastic anemia (mean cell volume > 100 fL) with vitamin B12 deficiency. The profile of anemia over 48 mo of follow-up was analyzed. RESULTS: One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed. The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery. The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery. Anemia of chronic disease and megaloblastic anemia were uncommon. The incidence of anemia in female patients was significantly higher than in male patients at 12 (40.0% vs 22.0%, P = 0.033), 24 (45.0% vs 25.0%, P = 0.023), 36 (55.0% vs 28.0%, P = 0.004), and 48 mo (52.0% vs 31.0%, P = 0.022) after surgery. Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery (60.7% vs 31.3%, P = 0.008). The incidence of iron deficiency was significantly higher in female patients than in male patients at 6 (35.4% vs 13.3%, P = 0.002), 12 (45.8% vs 16.8%, P < 0.001), 18 (52.1% vs 22.3%, P < 0.001), 24 (60.4% vs 20.9%, P < 0.001), 36 (62.5% vs 29.2%, P < 0.001), and 48 mo (66.7% vs 34.7%, P = 0.001) after surgery. CONCLUSION: Anemia was frequent after gastrectomy for early gastric cancer, with iron deficiency being the major cause. Evaluation for anemia including iron status should be performed after gastrectomy and appropriate iron replacement should be considered.

Frequency and characterisation of pancytopenia in megaloblastic anaemia.

BACKGROUND: A wide variety of clinical conditions, that primarily or secondarily affect the bone-marrow may present with pancytopenia, one of such conditions is megaloblastic anaemia. The purpose of this study was to determine the frequency and nature of pancytopenia in megaloblastic anaemia. METHODS: This was a prospective, cross-sectional descriptive study conducted in Medical Units, Ayub Teaching Hospital, Abbottabad, Pakistan during July 2010-January 2011. Total 90 patients were included in this study. Data were collected including history, clinical examination, haemoglobin level, mean cell volume, bone marrow examination and peripheral smear examination. RESULTS: Of total 90 patients, 54 were male and 36 were female. Mean age was 28 +/- 15.84 years. Common presenting features were weakness, fever and bleeding manifestations. Pancytopenia was present in 63 (70%) patients. Most common presenting feature related to anaemia was weakness (80%). Bleeding manifestations, related to low platelet count were found in 35 (39%) patients. Physical Examination findings were: pallor (100%), splenomegaly (33%), bleeding manifestations (25%), hepatomegaly (17%), and hepatosplenomegaly (19%). Mean peripheral blood findings of the study population included haemoglobin level (6.25 g/dL), total leukocyte count (2818.7/microL), platelet count (44040/uL), and reticulocyte count (1.7%). Mean values for red cells indices included red blood cells count (2.6 million/uL), mean corpuscular volume (114.3 fL), mean corpuscular haemoglobin (27.3 pg) and mean corpuscular haemoglobin concentration (31.8 g/dL). CONCLUSIONS: In megaloblastic anaemia, pancytopenia is a common and important clinical and haematological problem. Patients should be properly investigated for pancytopenia and its causes because many of them are completely curable while others are manageable. This will help to reduce patients' suffering, improve quality of life and prolong survival.

Bone marrow examination in pancytopenia.

Pancytopenia is defined by reduction of all the three formed elements of blood below the normal reference. It may be a manifestation of a wide variety of disorders, which primarily or secondarily affect the bone marrow. Haematological investigation forms the bedrock in the management of patients with pancytopenia and therefore needs detailed study. The total number of cases studied were 100 over a period of two years in the department of pathology, JSS Hospital, Mysore. Megaloblastic anaemia (33%) was the commonest cause of pancytopenia. Other causes were nutritional anaemia (16%), aplastic anaemia (14%), hypersplenism (10%), sepsis (9%) and leukaemia (5%). Less common causes were alcoholic liver disease, haemolytic anaemia, HIV, dengue, systemic lupus erythematosus, viral hepatitis, disseminated TB and multiple myeloma. Most of the patients were in the age group of 11-30 years with a male:female ratio of 1.6:1.Generalised weakness and fatigue (88%) were the commonest presenting complaints. Haemoglobin level varied from 1-10 g/dl with majorIty (70%) of them in the range of 5.1-10 g/dI. TLC was in the range of 500-4000 cells/cmm. Most (34%) of them had 3100-4000 cells/cmm. Platelet count was in the range of 4000-1,40,000 cells/cmm. Reticulocyte count varied from 0.1%-15% with majority (82%) of them ranging from 0.1%-2%. The bone marrow cellularity was hypocellular in 14%, hypercellular in 75%, and normocellular in 11% of the patients. Pancytopenia is a relatively common entity with inadequate attention in Indian subcontinent. A comprehensive clinical and haematological study of patients with pancytopenia will usually help in the identification of the underlying cause. However in view of wide array of aetiologies, pancytopenia continues to be a diagnostic challenge for haematologists.

Nutritional B12 deficiency in infants of vitamin B12-deficient mothers.

AIM: Nutritional vitamin B12 deficiency in infants may occur because the maternal diet contains inadequate animal products. Clinical presentations of the infants who had nutritional vitamin B12 deficiency were analyzed in this study. SUBJECTS AND METHODS: Patients with nutritional vitamin B12 deficiency were enrolled in the study between 2003 and 2010. The diagnosis was based on a nutritional history of mothers and infants, clinical findings, hematological evaluation, and low level of serum vitamin B12. RESULTS: Thirty children aged 1 - 21 months constituted the study group. Poverty was the main cause of inadequate consumption of animal products of the mothers. All infants had predominantly breastfed. The most common symptoms were developmental delay, paleness, apathy, lethargy, anorexia, and failure to thrive. Hematological findings were megaloblastic anemia (83.3 %), thrombocytopenia (30 %), and severe anemia (13.3 %). All of the mothers had low serum B12 levels; eight of them had megaloblastic anemia. CONCLUSION: The unusual clinical manifestations of vitamin B12 deficiency may also be seen apart from neurological and hematological findings. Nutritional vitamin B12 deficiency due to maternal deficiency might be a serious health problem in infants. Therefore, screening and supplementation of pregnant and lactating women to prevent infantile vitamin B12 deficiency should be considered.

Anemia en el anciano / Anemia in the elderly

La anemia es un problema frecuente en las personas mayores y está relacionada con un aumento de la morbilidad y mortalidad. En las personas ancianas aunque la anemia tiene una prevalencia elevada, existen diversos aspectos como el umbral de hemoglobina por debajo del cual debemos preocuparnos o la identificación de las causas de la misma que no son fáciles de establecer. La presente revisión se centra en conocer lo que se considera niveles de hemoglobina normales en los adultos, las causas más frecuentes de la anemia y sus posibles consecuencias en pacientes de edad avanzada. Se aporta un algoritmo diagnóstico y una aproximación al tratamiento en que se abordan nuevas posibilidades terapéuticas como el hierro parenteral y los agentes estimulantes de la eritropoyesis(AU)

Anemia is a common disorder in the elderly and is associated with increased morbidity and mortality. In elderly subjects, in whom anemia is highly prevalent, there are several aspects, such as a hemoglobin at a level which should concern us limit, or identifying its causes, that are not easy to establish. This review focuses on knowing what is considered to be normal hemoglobin levels in adults and the common causes and potential consequences of anemia in elderly patients. It provides a diagnostic algorithm and an approach to treatment that addresses new treatments such as parenteral iron drugs and erythropoiesis-stimulating agents(AU)

Megaloblastic anemia: back in focus.

Megaloblastic anemia (MA), in most instances in developing countries, results from deficiency of vitamin B(12) or folic acid. Over the last two to three decades, incidence of MA seems to be increasing. Of the two micronutrients, folic acid deficiency contributed to MA in a large majority of cases. Now deficiency of B(12) is far more common. In addition to anemia, occurrence of neutropenia and/or thrombocytopenia is increasingly being reported. Among cases presenting with pancytopenia, MA stands out as an important (commonest cause in some series) cause. This article focuses on these and certain other aspects of MA. Possible causes of increasing incidence of MA are discussed. Observations on other clinical features like neurocognitive dysfunction, associated hyperhomocysteinemeia and occurrence of tremors and thrombocytosis during treatment are highlighted.

Thiamine responsive megaloblastic anemia.

This report describes a female child with thiamine responsive megaloblastic anemia syndrome (Rogers syndrome), presenting with anemia and diabetes mellitus responding to thiamine. She also had retinitis pigmentosa. The anemia improved and blood sugar was controlled with daily oral thiamine. Previously unreported olfactory abnormalities, as described in Wolfram syndrome, were also present in our patient.

Vitamin B12 deficiency--a major cause of megaloblastic anaemia in patients attending a tertiary care hospital.

BACKGROUND: Folate and vitamin B12 deficiencies have been known to cause megaloblastic anaemia. Since the deficiencies of these two vitamins are very common in Pakistani population, it would be imperative to investigate their role in causing megaloblastic anaemia. The objective of this study was to find out the contribution of folate and vitamin B12 deficiencies in causing megaloblastic anaemia in our patient population. METHODS: In this retrospective cohort study, clinical records of 220 patients (101 females and 119 males with an age range of 1-80 years) who presented themselves with macrocytic anaemia at the Aga Khan University Hospital were collected. Data pertaining to complete blood count and serum levels of folate and vitamin B12 were analysed. RESULTS: The mean haemoglobin (Hb) level was 6.8 +/- 0.2 gm/dl. Sixty-nine percent of the patients had severe anaemia (Hb < 8 gm/dl). Mean +/- SEM values of haemoglobin, serum folate and serum B12 were not significantly different between males and females (Hb 6.4 +/- 0.3 gm/dl vs 6.3 +/- 0.3 gm/dl; folate 6.9 +/- 0.8 etag/ml vs 7.8 +/- 1 etag/ml; B12 259 +/- 65 rhog/ml vs 225 +/- 45 rhog/ml, respectively). Linear regression analysis showed that serum folate was inversely related with the mean corpuscular volume (MCV, p = 0.04). Spearman's correlation analysis indicated an inverse mild association between MCV and serum folate (correlation coefficient = -0.18). Folate deficiency was 43.4%, while vitamin B12 deficiency was 78.5% in these patients. Seventy-one percent of folate-deficient patients had vitamin B12 deficiency as well, while 26.1% of patients with B12 deficiency had a co-occurrence of folate deficiency. CONCLUSION: Vitamin B12 deficiency appears to be the major factor leading to megaloblastic anaemia in our study population. Inadequate dietary intake, over-cooking of our food and poor absorption might be contributing to high prevalence of vitamin B12 deficiency in this population.

Megaloblastic anaemia: prevalence and causative factors.

BACKGROUND: Megaloblastic anaemia is not uncommon in India, but data are insufficient regarding its prevalence, and causative and precipitating factors. We did a prospective study to document such data for patients of megaloblastic anaemia. METHODS: All patients presenting to our hospital over a period of 6 months with a haemoglobin < 10 g/dl and/or mean corpuscular volume > 95 fL and blood film findings consistent with megaloblastosis were included in the study. Demographic data, diet, drug intake, previous blood transfusion and presenting symptoms were recorded. Clinical findings were obtained from medical records of patients. Complete blood counts, blood film examination, reticulocyte count and cobalamin and folate assays were done. Results of liver function tests and bone marrow slides were available for review. RESULTS: Megaloblastic anaemia was diagnosed in 175 patients with anaemia. Assays were done on 120 patients (55 were lost to follow up) and results showed cobalamin deficiency in 78 patients (65%), combined cobalamin and folate deficiency in 20 patients (12%) and pure folate deficiency in 8 patients (6%). Fifteen per cent of patients had normal or high values of both vitamins, having received blood or haematinics before the diagnosis was established. The peak incidence of megaloblastic anaemia was in the age group of 10-30 years (48%), with female preponderance (71%). The predominant symptoms were fatigue, anorexia and gastritis, low grade fever, shortness of breath, palpitations and mild jaundice. Twenty-five per cent of patients were on acid-suppressing medication and 15% had previous transfusion for anaemia. Eighty-seven per cent of patients with cobalamin deficiency and 75% with folate deficiency were lactovegetarians. In the combined deficiency cohort, 71% were vegetarians and 29% were occasional non-vegetarians. Physical findings were pallor (85%), glossitis (29%), mild icterus (25%) and hyperpigmentation (18%). Abnormal haematological findings were mean corpuscular volume 77-123 fL (9 patients had iron deficiency), red cell distribution width 16%-44%, pancytopenia in 62% of patients, reticulocyte count > 2% in 42% of patients and typical megaloblastic blood films in all patients. Bone marrow smears available in 22 patients showed moderate-to-severe megaloblastosis. Thirty-two per cent of patients in whom liver function tests were done showed indirect bilirubinaemia with normal enzymes. CONCLUSION: Megaloblastic anaemia was diagnosed from complete blood counts, red cell indices, blood film examination and assays of the two vitamins. Bone marrow examination was not essential for diagnosis. Cobalamin deficiency was the major cause of megaloblastosis. Aetiological factors were a diet poor in cobalamin or folate, increased requirements during the growth period and pregnancy, and the use of acid-suppressing medication. Physicians managing these patients need to be aware of the timing of blood sampling for assays, that haematinics and transfusions provide only short term benefits, and that long term follow up and diet counselling is crucial.

Incidence of megaloblastic anaemia and its correction in leishmaniasis--a prospective study at BPKIHS hospital, Nepal.

Fifty (50) cases of Leishmaniasis were included in a prospective study after making the diagnosis based on the demonstration of L D Bodies on bone marrow aspirate. Hemoglobin (Hb) and total leucocyte count (TLC) were less than 10 gm/dl and 4000 per/ml respectively in 22 out of 50 cases. Among 50 cases, 30 showed macrocytic red cell and hypersegmented neutrophils on peripheral blood smear as features of megaloblastic anemia. Out of 30 cases of leishmaniasis with megaloblastic anemia, 10 cases showed decreased reticulocyte count. Bone marrow aspiration cytology showed megaloblastic maturation in erythroid series and giant metamyelocytes in myeloid series in all 30 cases of leishmaniasis with megaloblastic changes. Bone marrow iron was also increased in these cases. However megakaryocyte was normal in all. Among 30 cases of leishmaniasis with megaloblastic changes, 15 cases were treated with sodium antimony gluconate (SAG) only and other 15 with SAG, folic acid and Vit. B12. Rest 20 cases of leishmaniasis without megaloblastic changes were also treated with SAG only. After treatment with SAG alone as well as with SAG, folic acid and vit. B12, hemoglobin and TLC improved in all 50 cases. Of 15 cases of leishmaniasis with megaloblastic changes, who were treated with SAG, folic acid and vit. B12, the reticulocyte count reached at peak on the 7th day and normalized at the end of 4th week. Red blood cells (RBC) also became normocytic normochromic and neutrophils became normal on peripheral blood smear. But no change was observed in reticulocyte count, RBC and white blood cell (WBC) morphology on peripheral blood smear in cases of leishmaniasis without megaloblastic changes and other 15 cases of leishmaniasis with megaloblastic changes, who received SAG only.

Spectrum of anemia in pregnant Indian women and importance of antenatal screening.

Anemia is a common health problem but control of anemia in pregnant women is less well studied. The purpose was to study prevalence of anemia in young pregnant women, correlate with indices and study significance of identification of hemoglobinopathies. Of the 120 pregnant women, Hb was less than 8 g% in 58 (44.2%). Seventy-eight (65%) had iron deficiency, 22 (18.3%) had dimorphic anemia, and 14 (11.6%) had hemolytic anemia. Megaloblastic anemia was present in 6 (5%). Of hemolytic anemia, 50% were thalassemia trait. MCV< 76 fl was observed in 88 (73.3 %) cases. MCV<76 fl and MCH < 27 pg had 100 % sensitivity and 28.7 % specificity for screening of beta-thalassemia trait. NESTROFT had comparable sensitivity but lower specificity (14.9%). Sixty-three percent (60/78) of IDA had increased RDW whereas 78 % (11/14) of hemolytic anemia had RDW value in normal range (p value< 0.05). MCV/RBC of <14 was more specific parameter (96.8%) for beta-thalassemia trait. Four high-risk couples were identified. Thus, moderate to severe anemia was observed in most pregnant women. Hemoglobinopathies should be screened in antenatal clinics to identify the couples that would need a prenatal test. A lower MCV/RBC with RDWin the normal range may be useful in screening for thalassemia trait in pregnant women.
