Evaluation of children with macrocytosis: clinical study

Magnitude and morphological types of anemia differ by age among under five children: A facility-based study

Background

World Health Organization recently acknowledged the proportion of anemia attributable to iron deficiency among under-five children could be lower than the previously assumed 50%. Ethiopia reported 8.6% and 12.3% prevalence of iron deficiency anemia by serum ferritin and soluble transferrin receptor respectively. However, evidence generated from large samples on the magnitude of different types of anemias is limited. We aimed to determine the prevalence and morphological types of anemia in relation to age.

Methods

A retrospective analysis was conducted using electronic records of hemoglobin and red blood cell indices of 4739 children of 6-59 months of age who visited Hawassa University Comprehensive and Specialized Hospital from May 2017 to May 2019. Microcytic hypochromic morphology combined with high red cell distribution width was used to estimate the prevalence of iron deficiency.

Results

About 44.7% of the children were anemic. Anemia affected 6-23 months old children (53.1%) more than 24-59 (37.2%) months (p < 0.001) with no difference among boys and girls. Iron deficiency and iron-deficiency anemia, as explained by microcytic hypochromic morphology with high red cell distribution width combined model, were estimated to be 38.6% and 24.1%, respectively. About 54% of anemic children had iron deficiency which was higher among 6-23 months (63.5%) than 24-59 months (41.8%) (P < 0.001; X2 = 98.883). Regardless of anemia status, iron deficiency was two-fold higher among 6-23 months old children than 24-59 months of age. On the contrary, normocytic normochromic anemia affected significantly 24-59 months old children (23.1%) compared to 6-23 months. Less than 6% of the total anemia was macrocytic showing no significant relation with age. About 96% of macrocytic anemia was coupled with high red cell distribution width, indicating folate and vitamin B12 deficiency.

Conclusions

Microcytic hypochromic anemia with high red cell distribution width was the most prevalent type affecting primarily under two children. Normocytic normochromic anemia was significant among 24-59 months while macrocytic anemia had no age-related pattern. An in-depth study of causes of anemia other than iron deficiency particularly among 24-59 months children is essential.

Comparison of the severity of cytopenias with etiologic factors in patients with pancytopenia and bicytopenia

Introduction

The aim of this study was to evaluate the severity of hematological findings according to etiology in patients with pancytopenia and bicytopenia.

Methods

Patients with bicytopenia and pancytopenia who were examined in Diyarbakir Children Hospital Pediatric Hematology and Oncology clinic between June 2017-June 2018 were evaluated retrospectively.

Results

Of the 130 patients included in the study, 73 (56.2%) were male and 43 (43.8%) were female. The mean age of the patients was 4.9 ± 4.86. Forty-five (34.6%) patients had pancytopenia and 85 (65.3%) had bicytopenia. The youngest patient was 1-month old and the oldest patient was 18-year-old. The mean blood count parameters were white blood cell (WBC): 10.207 ± 39.781, neutrophil: 1515 ± 1418, hgb: 9.3 ± 2.3, mean corpuscular volume (MCV): 80 ± 13.1, platelet: 118.823 ± 93.645. Three out of 130 patients had hyperleukocytosis (WBC > 50.000/mm³). Vitamin B12 deficiency was detected in 35 patients. When patients with primary hematological disease were compared with patients with secondary causes of cytopenias, a significant difference was found in terms of leukocyte count, hemoglobin level, MCV elevation, and low platelet count.

Conclusion

The determination of the severity of cytopenias in differential diagnosis may be useful in distinguishing primary hematological diseases from secondary causes of pancytopenia and bicytopenia. However, vitamin B12 deficiency in developing countries is one of the most important causes of public health as well as in the etiology of pancytopenia and bicytopenia.
