Background: Potential interactions between mood disorders and microcytic anaemias have been suggested by case reports, surveys of haematological parameters in psychiatric populations, and surveys of psychiatric morbidity in thalassaemic carriers. Objectives: a) To review published studies. b) To study the prevalence of microcytic anaemia in a sample of Sardinian outpatients with recurrent mood disorders. c) To check whether mood disorders and microcytic anaemia co-segregate within families. Methods: We extracted data on blood count and serum iron concentrations from the records of patients admitted between January 1st, 2001 and December 31st, 2016, to our clinic for mood disorders. Moreover, we studied siblings of subjects with both major mood disorders (according to Research Diagnostic Criteria) and heterozygous thalassaemia (according to Mean Corpuscular Volume, serum iron, and haemoglobin A2 concentrations). Siblings affected with a major mood disorder were examined for haematological concordance with the proband (reduced MCV and/or increased HbA2 in case of heterozygous β-thalassaemia, or presence of gene deletions in case of α-thalassaemia). Results: Microcytic anaemia was highly prevalent (81/337 = 24.0%) among outpatients with mood disorders. Starting from 30 probands with heterozygous ß-thalassaemia, concordance for reduced MCV and/or increased HbA2 was found in 78% (35/45) of affected siblings. Starting from 3 probands with heterozygous α-thalassaemia, only one of the 5 affected siblings carried four α-globin functional genes. Conclusion: Based on the review of the literature, the high prevalence of microcytic anaemia in outpatients, and the concordance between affected siblings, we can conclude that a role of heterozygous thalassaemias is highly probable. Future studies are required to establish the relevance of heterozygous thalassaemias and evaluate the magnitude of the effect, possibly using a molecular diagnosis also in the case of heterozygous β-thalassaemia.

Background. Anaemia, a common nutritional deficiency, is a public health problem in the Mount Cameroon area. This study determined the prevalence and possible risk factors of microcytic and malarial anaemia in children less than ≤15 years residing in the Buea and Limbe municipalities in the Mount Cameroon area. Methods. A total of 566 children were clinically examined in a cross-sectional study from December 2018 to August 2019 for anaemia and malaria parasites. Blood samples collected were used in evaluating full blood count with the aid of an automated haemoanalyser, and malaria parasite was confirmed by microscopy. Anaemia was defined based on WHO standards while microcytic anaemia and malarial anaemia were defined as microcytosis + anaemia and malaria + anaemia, respectively. Factors that showed significance in the bivariate analysis were entered into a multinomial logistic regression to determine risk factors for microcytic and malarial anaemia. Results. The overall prevalence for anaemia, microcytosis, microcytic anaemia, and malarial anaemia was, respectively, 68.7%, 48.9%, 36.9%, and 19.6% with microcytic anaemia representing 53.7% of all anaemic cases. Risk factors for microcytic anaemia included child age of 1–5 years P = 0.007 , forest ethnicity P = 0.019 , parents being farmers P = 0.038 or jobless P = 0.009 , and having moderate malaria parasitaemia P = 0.048 while those for malarial anaemia were child age of 6–10 years P = 0.008 , parents’ age of 26–35 years P = 0.049 , parents being jobless P = 0.023 , and consuming plantains 3-4 times P = 0.024 a week. Conclusion. Microcytic anaemia is getting to be a severe public health concern while malarial anaemia is a mild public health issue in children residing in urban areas of Mount Cameroon. Parents’ occupation was directly linked to all anaemia forms; hence, any intervention to curb anaemia should consider aspects that will raise the socioeconomic status of the population.

Abiotrophia defectiva is a rare agent of endocarditis and subacute presentation may delay the diagnosis. We present the case of a 41-year-old male who was admitted to the hospital for further investigation regarding a consumptive syndrome with microcytic anaemia. Past medical history included new-onset mitral insufficiency followed by an ischaemic stroke due to small vessel disease. Thoraco-abdominal computed tomography revealed a splenic infarction. In the presence of two ischaemic events associated with mitral valve disease of unknown aetiology, we considered the possibility of subacute endocarditis. Blood cultures were positive for Abiotrophia defectiva, and transoesophageal echocardiography confirmed the diagnosis. As a subacute presentation of endocarditis, the paucity of symptoms caused a five-month delay in diagnosis. New-onset valvular disease and a stroke in an otherwise healthy young patient should always prompt proper investigation. This case highlights several complications caused by septic emboli of undiagnosed and untreated endocarditis.

Background: Iron deficiency anaemia (IDA) is the prevalent form of anaemia which has become a major public health problem, globally. Women in the reproductive age group (15–49 years of age) are at increased risk, especially in the South Asian population. It is of paramount importance to identify these micronutrient deficiencies in this age group as it adversely affects the birth outcomes, but the mother and the child at risk of morbidity and mortality during pregnancy.  Methods: A cross-sectional study was conducted at Civil Hospital, Karachi for 12 months i.e. October, 2018 to December, 2019. Data was prospectively collected from patients after obtaining written informed consent. 377 patients were included who met the diagnostic criteria. Descriptive statistics were used and qualitative data analysis; mean, standard deviation, frequency, and percentages were respectively calculated. Effect modifiers were controlled through stratification to see the effect of these on the outcome variable. For post-stratification, the chi-square test was applied with a p value of≤0.05.Results: A total of 377 patients with microcytic anaemia were enrolled from Civil Hospital, Karachi. Mean age, duration of anaemia, haemoglobin, height, weight and BMI in our study was 29.28±6.14 years, 1.41±0.26 months, 9.27±0.86 mg/dl, 26.72±1.56 kg/m2, 138±7.28 cm and 78.7±9.87 kg. Out of 377 patients with microcytic anaemia, 144 (38.2%) and 233 (61.8%) had and did not have iron deficiency anaemia.  Conclusions: IDA is frequently found in microcytic anaemia patients. Thus, it is important to screen premenopausal in female patients for iron deficiency presenting with microcytic anaemia to prevent adverse outcomes.

Objective: This study aimed to determine the prevalence of anaemia in children aged six months to fifteen years old treated in a single centre from 2008 to 2018. Methods: A retrospective study was conducted among 274 children age six months to fifteen years old, treated in Advanced Medical and Dental Institute (AMDI), Universiti Sains Malaysia (USM) from 2008 to 2018. The data was obtained from computerised hospital data (CARE2X), Laboratory Information System (LIS) or medical record. Parents of the eligible participants were called for any incomplete data and verbal consents were obtained. Descriptive analysis was conducted to determine the prevalence whereas the relationship between independent variables with types of anaemia were examined using simple logistic regression. Results: The prevalence of anaemia was 22.3%. Among the anaemic children, the predominant morphology form was hypochromic microcytic anaemia (82%) followed with normochromic normocytic anaemia (18%). Iron deficiency anaemia (IDA) was found to be the commonest cause (24%) of hypochromic microcytic anaemia, followed by IDA with concomitant thalassaemia (14%) and thalassaemia alone (8%). In simple logistic regression analysis, no significant association was found. Conclusions: The prevalence of anaemia was 22.3%, which is considered as moderate public health problem according to WHO. Hypochromic microcytic anaemia was the predominant red cell morphology (82%) and IDA was the commonest causes (24%).

Abstract Objective: To study the frequency and types of haemoglobinopathies in children with microcytic anaemia. Method: The prospective study was conducted at the Paediatric Out-patient Department of Shifa Falahi Community Health Centre, Islamabad, Pakistan, from July to December, 2018, and comprised patients aged from 3 months to 14 years who had haemoglobin <10mg/dl and mean corpuscular volume <70fL. Serum ferritin and haemoglobin electrophoresis were done to check for iron deficiency anemia and haemoglobinopathies. Data was analysed using SPSS 23. Results: Of 175 subjects, 33(18.9%) had haemoglobinopathies and 142(81.1%) had iron deficiency anaemia. Thalassemia trait 18(10.3%) was the leading cause amongst haemoglobinopathies, followed by thalassemia major 8(4.6 %) and intermedia 5(2.9%). There were 2(1.1%) patients with haemoglobin D. Conclusion: The prevalence of hemoglobinopathies was high. Identification of haemoglobinopathies is important for proper treatment, antenatal screening and future genetic counselling. Key Words: Haemoglobinopathy, Iron deficiency anaemia, Microcytic, MCV, IDA.

We describe a dominant β-thalassaemia caused by a deletion of G at nucleotide position 364 in exon 3 of the β-globin gene. The heterozygosity of this mutation was found in a 36-year-old Thai patient who had moderate hypochromic microcytic anaemia with haemolytic blood picture. Haemoglobin (Hb) analysis revealed relatively higher Hbs A2 (6.8%) and F (4.7%) as compared with those of β0-thalassaemia (n=278) and β+-thalassaemia (n=55) carriers in our series. Secondary structure prediction of the elongated β-globin chain showed that the α-helix at the C-terminal is disrupted dramatically by the random coil and β-sheet, which should result in a highly unstable β-globin variant, undetectable in peripheral blood and a dominant clinical phenotypic feature.

Introduction: Haemoglobin A1C (A1C), as a parameter of long-term glycaemic control, has been adopted to guide diabetic therapy all over the world. However, falsely high or low A1C could be troublesome in daily practice. Case description: A 75-year-old male diabetic patient affected by a reasonably inferred life-long history of microcytic anaemia was found to have abnormally low A1C values in the previous 5 months. Subsequent laboratory assessment with brilliant cresyl blue staining and haemoglobin electrophoresis detected haemoglobin H disease as the underlying cause of both the microcytic anaemia and the disturbed A1C measurement. Discussion: Enhanced erythrocyte destruction such as in haemoglobin H disease could explain a falsely decreased A1C level very well. Upon facing a questionable A1C value, physicians dealing with diabetes should consider the possibility of undiscovered underlying causes rather than too tightly glycaemic control.
