Background: A link between major depressive disorder (MDD) and haematological as well as co-agulation disorders has been postulated. This study aims to evaluate haematological and haemostatic changes among Nigerians with major depressive disorder Methods: Two hundred volunteers consisting of an equal number of individuals diagnosed with major depressive disorder (MDD) based on DMS-IV criteria and apparently healthy control participated in this study. The blood sample was collected into tri-sodium citrate K2EDTA bottles respectively and was evaluated for some haemostatic parameters , using ELISA, Clauss, Quick’s One Stage, Proctor and Rapaport’s methods. Results: The mean WBC, hemoglobin and differential lymphocyte were significantly higher among MDD total volunteers (p < 0.001). The red cell indices and platelet count were lower among MDD (p <0.001). Also the prothrombin time (PT), fibrinogen, protein-C and erythrocytes sedimentation rate (ESR) were all raised (p <0.001) among volunteers with MDD. Positive associations existed be-tween MCV and RBC (r: 0.364; p<0.001), PT and APTT (r: 0.319 p <0.001), APTT and fibrinogen (r: 0.239, p = 0.017) as well as PT and fibrinogen (r: 0.275 p = 0.006) at 95% confidence interval. Conclusion: Changes in total leucocytes count, lymphocytes values and haemostatic parameters among volunteers with depression may impacts deleterious effects on the immune response as well as haemostatic homeostasis, while decreased red cell indices may suggest occult nutritional anaemia.


Background and aim Deficiency of vitamin D is known as a health problem all over the world and a recognized clinical complication of beta thalassemia patients. Vitamin D acts as a hormone at the nuclear receptor rendering it a beneficial medication for a number of diseases. It is believed that vitamin D is important in the modulation of the inflammation system by regulating the formation of inflammatory cytokines and immune cells. This study aimed to investigate the effect of vitamin D supplementation on the red cell indices and cytokines levels in patients with beta thalassemia major, in an open label randomized clinical trial. Patients and Methods: this study performed an open-label randomized clinical trial in patients with beta thalassemia major. Forty-six patients completed the eight weeks clinical trial and were allocated to administer oral vitamin D3 supplement of 100,000 IU every two weeks as an add-on treatment. During the study, hematological indices, serum iron, ferritin, vitamin D, calcium and inflammatory markers (interleukin-6, interleukin-2 and interleukin-10) were evaluated before (at baseline) and after vitamin D supplementation for 8 weeks. Results: Vitamin D3 supplements significantly decreases interleukin-6 levels and elevates the serum levels of anti-inflammatory cytokines IL-2 and IL-10, it also significantly reduced serum ferritin level, but it did not alter the hematological indices. Conclusion: Our results suggest that administration of vitamin D has a potential anti-inflammatory role in beta thalassemia patients and reduces serum ferritin levels, which may reduce the burdens of iron overload in thalassemia patients.

BACKGROUND Thyroid hormones play an important role in the regulation and production of red blood cells. Thyroid dysfunction induces different effects on blood cells such as anaemia, erythrocytosis, leucopenia, thrombocytopenia and alteration in red cell indices. In this study, we wanted to compare the changes in haematological parameters of thyroid dysfunction patients with those of euthyroid group. METHODS This was a retrospective study done on 310 individuals by collecting data from the medical records. Later the patients were categorized into hypothyroid (33) thyroid stimulating hormone (TSH > 5.5 μIU/mL), hyperthyroid (19) (TSH < 0.3 μIU/mL) and euthyroid (258) (TSH = 0.3 - 5.5 μIU/ml) groups. The haematological parameters of all these patients were obtained by 5-part automated cell count analyser. Finally, the obtained data was analyzed by statistical package for social sciences (SPSS) software. RESULTS The data obtained from the analysis revealed statistically significant (P < 0.05) difference between hypothyroidism, hyperthyroidism and euthyroidism in mean red blood cell (RBC) count, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), red cell distribution width (RDW), white blood cell (WBC) count and platelet count but the difference was not significant for mean haemoglobin, mean corpuscular haemoglobin concentration (MCHC) (P > 0.05). The mean haemoglobin was lower in hypothyroid patients when compared to euthyroid and hyperthyroid patients. The RBC count (P < 0.007), MCH (P = 0.002) and RDW (P < 0.001) showed statistically significant difference between hypothyroidism and euthyroidism, MCV (P = 0.005) showed statistically significant difference between hyperthyroid and euthyroid groups. CONCLUSIONS In case of patients with abnormal haematological parameters, thyroid hormones evaluation is necessary.

Background: Fetal iron stores are affected by maternal diabetes and it is lower at birth in infants of diabetic mothers (IDMs). Risks for developing iron deficiency and neurocognitive impairment are reported in IDMs. This study was done to assess serum ferritin and red cell indices in IDMs and to compare the values with infants born to mothers without diabetes mellitus. Methods: This cross-sectional study was carried out at BIRDEM General Hospital from March to October, 2018. Total 102 full term neonates were included in this study. Among them 70 neonates were IDMs and 32 were infants born to mother without diabetes mellitus. Serum ferritin and red cell indices like hemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW) were measured within 48 hours of birth. Comparison of red cell indices and serum ferritin level were done between IDMs and infants of non-diabetes mothers. Statistical analysis was performed by using Epi info, and p value of <0.05 was considered statistically significant. Results: IDMs had significantly higher value of Hb% (19.00 vs 17.47 g/dl), PCV (57.60 vs 52.67 %) and RDW (20.09 vs17.77 %) than infant of non-diabetic mother (p <0.05). But there was no significant difference regarding the values of MCV, MCH and MCHC between IDMs and infants of non-diabetic mothers (p >0.05). Serum ferritin level was found significantly low in IDMs (94.51 vs 307.50 ng/ml, p <0.001). Conclusion: Iron stores of IDMs were found significantly lower at birth despite higher hemoglobin content, as indicated by lower serum ferritin level. Further studies and long-term follow up are needed to determine whether these infants are at risk for developing iron deficiency anemia or iron-deficient neurocognitive disorder Birdem Med J 2020; 10(3): 182-186
