RESUMEN
Introduction: Anaemia is a commonly encountered condition among the elderly population which calls for further evaluation to identify the cause and to prevent complications. Objectives: To determine the prevalence, causes and complications related to anaemia among elderly patients admitted to two medical wards (15/16) of Colombo North (Teaching) Hospital, Ragama, Sri Lanka. Methods: Patients aged over>65 years admitted to the above wards between April -Sep 2020 and who had anaemia were included in the study. Clinical and nutritional data were collected using an interviewer-administered questionnaire. Laboratory findings were extracted from hospital records. Results: The majority of the patients were females (63.2%; n = 129). The mean age was 72.5 years (65 - 92 years). Most of the patients (62.3%; n = 127) were symptomatic for anaemia at the time of hospital admission. The majority of the participants (75.5%; n = 154) did not demonstrate any complications related to anaemia. The severity of the anaemia was moderate among more than half of the patients (52.5%; n=107). Anaemia of chronic disease (54.4%; n=111) was the commonest etiological category detected. The majority of the cases with anaemia of chronic disease were due to chronic renal insufficiency (73.9%; n=82). The severity of the anaemia increased significantly with the presence of chronic disease (p 0.030). Conclusion: Most patients in the present study had moderate anaemia whilst anaemia of chronic disease was the leading aetiological class contributor. Community-based studies are needed to understand the true burden of anaemia in the ageing population in Sri Lanka.

BACKGROUND: Imerslund-Gräsbeck syndrome is a rare genetic disease characterised by vitamin B12 deficiency and proteinuria. CASE PRESENTATION: A 4-year old Sri Lankan boy presented with gradually worsening difficulty in walking for two weeks duration. He was previously diagnosed and managed as having non-transfusion-dependent α-thalassaemia based on the presence of hypochromic microcytic anaemia, haemoglobin H inclusion bodies in the blood film and compound heterozygous α-thalassaemia genotype with a gene deletion. However, his transfusion requirement increased over the past three months and he gradually lost his motor developmental milestones during two weeks before admission. The neurological examination revealed generalised hypotonia, exaggerated knee jerks and extensor plantar response. His complete blood count showed pancytopenia, and bone marrow biopsy revealed megaloblastic changes. Serum vitamin B12 and red blood cell folate levels were low. MRI revealed sub-acute combined degeneration of the spinal cord with characteristic 'inverted V sign'. Urine analysis showed non-nephrotic range proteinuria. The diagnosis of Imerslund-Gräsbeck syndrome was made due to the presence of non-nutritional vitamin B12 deficiency and asymptomatic proteinuria. He showed a rapid haematological and neurological improvement to intramuscular hydroxocobalamin. CONCLUSIONS: This case report presents a rare occurrence of severe vitamin B12 deficiency due to Imerslund-Gräsbeck syndrome masked by co-existent α-thalassaemia, resulting in serious consequences. It highlights the need for a high index of suspicion in evaluating children with severe anaemia, especially in the presence of mixed pathologies.

Microcytic anemia in children is commonly attributed to iron deficiency without attempting to find the cause. Inadequate investigations to exclude hemoglobinopathies lead to missed opportunities for identification of thalassemia carriers. Here we aim to describe the relative contribution of iron deficiency and thalassemia to microcytic anemia in children. This hospital-based prospective study was conducted at the Colombo North Teaching Hospital, Ragama, Sri Lanka. All newly diagnosed patients with microcytic anemia were recruited and data were collected using an interviewer-administered questionnaire. Full blood count, blood film, serum ferritin, c-reactive protein, quantification of hemoglobin sub-types and α-globin genotype were performed using 4 ml of venous blood. A total of 104 children (Male- 60.5%) were recruited. Iron deficiency was the cause for anemia in 49% whilst 16% and 10% had α- and ß-thalassemia trait respectively. Seven (6.7%) children had co-existing iron deficiency and thalassemia trait while two coinherited α- and ß-thalassemia trait. Children with ß-thalassemia trait had significantly higher red cell count and lower mean corpuscular volume compared to children with iron deficiency. However, none of the red cell parameters were significantly different between children with α-thalassemia trait and iron deficiency. Iron deficiency contributes only to half of children with microcytic anemia; one-fourth had thalassemia trait. Co-existence of iron deficiency and thalassemia trait or co-inheritance of α- and ß-thalassemia trait were found in 9%. Parallel investigation of children with microcytic anemia to diagnose iron deficiency and thalassemia provides an opportunity to identify thalassemia carriers which is beneficial for thalassemia prevention.
