Vitamin B12 deficiency is uncommon in pregnancy, it occurs in 10–28% of uncomplicated pregnancies, and is associated with a few complications. We present a case report of a 21-year-old patient with severe anaemia during late pregnancy caused by vitamin B12 deficiency. At 38 weeks gestation and with a BMI of 48.9, a history of rupture of membranes was given but not confirmed. On examination, she appeared pale and therefore full blood counts were done. Interestingly her haemoglobin (Hb) levels were 3.7 g/dL. Folate and vitamin B12 levels were also found to be low, and the diagnosis of anaemia caused by vitamin B12 deficiency was made. After treatment with vitamin B12 injections, folic acid and blood transfusions, the patient’s haemoglobin levels improved from 3.7 g/dL to 10.7 g/dL. The conclusion is that effective history taking, diagnosis, and management can prevent many complications that are usually associated with vitamin B12 deficiency anaemia.

Background: Folate and vitamin B 12 deficiency can lead to pancytopenia in pregnancy. Some cases of pancytopenia due to COVID-19 infection have also been reported. The two cases that we present are related to the coincidence of pregnancy and deficiency of folic acid and vitamin B12 with COVID-19 infection. Case presentation: A 26-year- woman G3P1L1A1 and 21-year-woman G2P1L1 presented with pancytopenia and mild COVID-19 infection. The antenatal period was uneventful, and both cases also had folate and vitamin B12 deficiency. They received blood products, folic acid, and vitamin B12 supplementation. COVID- 19 infection was managed well with analgesic and vital monitoring. Postpartum hemorrhage occurred in the second case, which was well managed with uterotonics. All laboratory parameters came out to be normal after three months of supplementation of folic acid and vitamin B12. Conclusion: Pancytopenia in pregnancy due to folate and vitamin B12 deficiency and COVID- 19 infection can be easily managed with timely intensive targeted therapy, but we should be extra vigilant while handling such complicated cases, keeping in mind all possible differential diagnoses for pancytopenia.

Vitamin B12 is known to be vital for cell growth and population during pregnancy. This retrospective and prospective case−control study was aimed to disclose a health risk for pregnant women with vitamin B12 deficiency, as well as the one of the preterm birth. The main tasks set and performed in this research were as follows: to compare the obstetrics anamnesis between the women who gave birth on term and women who gave birth before term; to find the prevalence of vitamin B12 insufficiency in pregnancy; to determine its association with preterm birth and low birth weight; to examine its association with spontaneous abortions, and to investigate its relationship with obesity and hemoglobin levels in pregnant women. The conducted investigation involved 107 women who gave birth before the 37th week of gestation and 101 women who gave birth after the 37th week of gestation at the outpatient clinic of the University Hospital "Maichin Dom" in Bulgaria. Our study revealed a correlation between maternal vitamin B12 deficiency, overweight and low hemoglobin level. Our results showed no significant correlation between serum vitamin B12 level and the risk of preterm birth. However, we found an inverse association between vitamin B12 level and overweight before pregnancy and at the time of giving birth. As well there was confirmed the strong connection between meat consumption and vitamin B12 level. The paper emphasizes that the deficiency of the vitamin occurs most likely in the women with inadequate diets. Such a deficiency is actually confirmed to have serious health consequences for pregnant women and their offspring. Therefore further profound and numerous studies should be performed to properly assess the correlation between vitamin B12 and preterm birth, as well as to understand better the impact of vitamin B12 over pregnant women. Key words: vitamin B12, preterm birth, pregnancy, overweight, hemoglobin.

Abstract 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.

Abstract Alterations in reticulocyte size occur 2–3 days after the onset of iron deficient or megaloblastic erythropoiesis and precede, by several weeks, changes in mean corpuscular volume (MCV). Iron-deficiency anemia induced in a normal subject by repeated phlebotomies was characterized by the initial development of larger than normal reticulocytes followed by an abrupt decrease in reticulocyte size. Microreticulocytes appeared 3 days after the fall in per cent iron saturation and antedated the decrease in MCV to below normal by 6 wk. Mean reticulocyte size was disproportionately smaller than normal in patients presenting with iron deficiency. In contrast, reticulocyte size increased abruptly in a patient (and rats) 2–3 days after administration of methotrexate. Mean reticulocyte size was disproportionately larger than normal in patients presenting with folate or vitamin B12 deficiency. Specific replacement therapy with iron, folate, or vitamin B12 was quickly followed by normalization of reticulocyte size.

Celiac disease (CD) is a multisystemic disorder with different clinical expressions, from malabsorption with diarrhea, anemia, and nutritional compromise to extraintestinal manifestations. Anemia might be the only clinical expression of the disease, and iron deficiency anemia is considered one of the most frequent extraintestinal clinical manifestations of CD. Therefore, CD should be suspected in the presence of anemia without a known etiology. Assessment of tissue anti-transglutaminase and anti-endomysial antibodies are indicated in these cases and, if positive, digestive endoscopy and intestinal biopsy should be performed. Anemia in CD has a multifactorial pathogenesis and, although it is frequently a consequence of iron deficiency, it can be caused by deficiencies of folate or vitamin B12, or by blood loss or by its association with inflammatory bowel disease (IBD) or other associated diseases. The association between CD and IBD should be considered during anemia treatment in patients with IBD, because the similarity of symptoms could delay the diagnosis. Vitamin B12 deficiency is common in CD and may be responsible for anemia and peripheral myeloneuropathy. Folate deficiency is a well-known cause of anemia in adults, but there is little information in children with CD; it is still unknown if anemia is a symptom of the most typical CD in adult patients either by predisposition due to the fact of age or because biochemical and clinical manifestations take longer to appear.

Severe vitamin B12 deficiency may present with hematologic abnormalities that mimic thrombotic microangiopathy disorders such as hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. We report a patient diagnosed with severe vitamin B12 deficiency, following termination of pregnancy for suspected preeclampsia and HELLP syndrome at 21 weeks’ gestation. When hemolysis and thrombocytopenia persisted after delivery, testing was performed to rule out other etiologies of thrombotic microangiopathy, including atypical hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, and vitamin B12 deficiency. This work-up revealed undetectable vitamin B12 levels and presence of intrinsic factor antibodies, consistent with pernicious anemia. Parenteral B12 supplementation was initiated, with subsequent improvement in hematologic parameters. Our case emphasizes the importance of screening for B12 deficiency in pregnancy, especially in at-risk women with unexplained anemia or thrombocytopenia. Moreover, providers should consider B12 deficiency and pernicious anemia in the differential diagnosis of pregnancy-associated thrombotic microangiopathy.
