B12 Deficiency

Background: Pancytopenia is one of the common laboratory findings in patients presenting to us with varied clinical presentations. Risks of untreated Pancytopenia are high causing anxiety to treating doctors and patients alike. It also involves long list of investigations including a very painful marrow biopsy, life-threatening complications and treatment involves multiple blood component therapy. A total of 101 cases of pancytopenia over a period of 1 year were analysed retrospectively to find i) commonest presenting symptoms ii) commonest cause of pancytopenia, response to treatment iii) Depending on the cause, to consider if any measures can be taken for preventionMethods: Cross sectional study of 101 admitted patients of Pancytopenia on the basis of information extracted from the case sheets. The data was analyzed and presented as frequencies and Percentages.Results: Out of 101 cases analysed, 53 (52.47%) were females 48 (47.52%) patients males. Fatigue 74 patients (73.2%) was the commonest presenting symptom followed by fever 33 (32.6%), breathlessness 13 (12.87%) and bleeding 4(3.8%). Vitamin B12 deficiency 58 (57.6%) patients showed and was the commonest cause of pancytopenia. Infections in 24 (23.7%) like malaria16 (15.6%), dengue 5 (4.96%), PLHA 1(0.96%) and hepatitis B 2 (1.96%) was the second common cause in present study. Recovery of pancytopenia was prompt in Malaria Dengue. HIV, Hepatitis B viral infection showed persistent pancytopenia with hypoplastic marrow. Chronic liver disease portal hypertension splenomegaly accounted for 9 (8.9%) patients. Drug induced marrow suppression due to ongoing treatment for underling disease resulted in pancytopenia in 4 (3.96%) patients. Aplastic anaemia in3 (2.9%), myelodysplastic syndrome 2 (1.9%) and acute leukaemia 1 (0.96%) were the less common causes.Conclusions: Commonest symptom on presentation were related more to anaemia than to neutropenia and thrombocytopenia. megaloblastic anaemia due to Vitamin B12 deficiency was the leading reversible cause of pancytopenia in present study followed by infections like Malaria Dengue. Gujarat, India being predominantly vegetarian state, local dietary habits are thought to be responsible for inadequate B12 daily consumption, hence we suggest fortifying the daily diet with B12 supplementation at a larger scale just like iodisation of salt to counter iodine deficiency.

Vitamin B12 Malabsorption

Vitamin B12 deficiency is common in people of all ages who consume a low intake of animal-source foods, including populations in developing countries. It is also prevalent among the elderly, even in wealthier countries, due to their malabsorption of B12 from food. Several methods have been applied to diagnose vitamin B12 malabsorption, including Schilling’s test, which is now used rarely, but these do not quantify percent bioavailability. Most of the information on B12 bioavailability from foods was collected 40 to 50 years ago, using radioactive isotopes of cobalt to label the corrinoid ring. The data are sparse, and the level of radioactivity required for in vivo labeling of animal tissues can be prohibitive. A newer method under development uses a low dose of radioactivity as 14C-labeled B12, with measurement of the isotope excreted in urine and feces by accelerator mass spectrometry. This test has revealed that the unabsorbed vitamin is degraded in the intestine. The percent bioavailability is inversely proportional to the dose consumed due to saturation of the active absorption process, even within the range of usual intake from foods. This has important implications for the assessment and interpretation of bioavailability values, setting dietary requirements, and interpreting relationships between intake and status of the vitamin.

Abstract. Vitamin B12 deficiency may have indirect cardiovascular effects in addition to hematological and neuropsychiatric symptoms. It was shown that the monocyte count-to-high density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel cardiovascular marker. In this study, the aim was to evaluate whether MHR was high in patients with vitamin B12 deficiency and its relationship with cardiometabolic risk factors. The study included 128 patients diagnosed with vitamin B12 deficiency and 93 healthy controls. Patients with vitamin B12 deficiency had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), MHR, C-reactive protein (CRP) and uric acid levels compared with the controls (median 139 vs 115 mmHg, p < 0.001; 80 vs 70 mmHg, p < 0.001; 14.2 vs 9.5, p < 0.001; 10.2 vs 4 mg/dl p < 0.001; 6.68 vs 4.8 mg/dl, p < 0.001 respectively). The prevalence of left ventricular hypertrophy was higher in vitamin B12 deficiency group (43.8%) than the control group (8.6%) (p < 0.001). In vitamin B12 deficiency group, a positive correlation was detected between MHR and SBP, CRP and uric acid (p < 0.001 r:0.34, p < 0.001 r:0.30, p < 0.001 r:0.5, respectively) and a significant negative correlation was detected between MHR and T-CHOL, LDL, HDL and B12 (p < 0.001 r: −0.39, p < 0.001 r: −0.34, p < 0.001 r: −0.57, p < 0.04 r: −0.17, respectively). MHR was high in vitamin B12 deficiency group, and correlated with the cardiometabolic risk factors in this group, which were SBP, CRP, uric acid and HDL. In conclusion, MRH, which can be easily calculated in clinical practice, can be a useful marker to assess cardiovascular risk in patients with vitamin B12 deficiency.

Vitamin B12 Supplementation

Introduction: An unusual case of a 19 year old female, presenting with fever, pallor and hepatosplenomegaly for one month. She had microcytic anemia on peripheral smear examination but her bone marrow aspiration & biopsy revealed a hypercelluar marrow with megaloblastic erythroid hyperplasia. Resolution of fever within 48 hours of Vitamin B12 supplementation, initiated in view of the megaloblastic bone marrow picture & low serumVitamin B12 level, suggests a causal association. Conclusion: Vitamin B12 deficiency seems to be an unusual cause of PUO (Pyrexia of unkown origin) which should be ruled out in every case of PUO.
