    Objectives: The association between vitamin D deficiency and anemia is known. Vitamin D deficiency and anemia are common in kidney transplant recipients. We examined the relationship between vitamin D levels and anemia in pediatric kidney transplant recipients. Materials and Methods: We reviewed retrospectively the data of 75 pediatric kidney transplant recipients (0-18 years of age). Patients were evaluated in 3 groups according to serum 25-hydroxyvitamin D levels (<20, 20-30, and >30 ng/mL) in the first year posttransplant: group 1 was the vitamin D deficiency group, group 2 was the vitamin D insufficiency group, and group 3 was normal vitamin D level group, respectively. Groups were compared in terms of anemia parameters, calcium, phosphorus, alkaline phosphatase, and parathyroid hormone levels, as well as infection, rejection, and graft loss status. All patients included in the study were grouped as those with anemia and without anemia, and the 2 groups were compared in terms of vitamin D levels, serum parathyroid hormone values, estimated glomerular filtration rate, and infection, rejection, and graft loss status. Results: There were 41 patients (54.7%) in group 1, 24 patients (32%) in group 2, and 10 patients (13%) in group 3. There were 65 patients (86.7%) with vitamin D deficiency/insufficiency. When groups were compared, the hematocrit level was found to be lower in groups 1 and 2 (P < .05) and ferritin level was found to be lower in group 1 (P < .05). Anemia was present in 20 patients (26.6%): 61% of patients with anemia had vitamin D deficiency and 33% had vitamin D insufficiency (P > .05). In total, 94% of patients with anemia had vitamin D deficiency/insufficiency. Conclusions: Vitamin D deficiency/insufficiency is common in pediatric kidney transplant recipients. Vitamin D levels should be measured, especially in all kidney transplant recipients with persistent anemia. Thus, risk factors associated anemia can be reduced by treating the deficiency/insufficiency.

    Comparison of Clinical Features and Laboratory Findings of Coronavirus Disease 2019 and Influenza A and B Infections in Children: A Single-Center Study
    (2021) Siddiqui, Meraj; Gultekingil, Ayse; Bakirci, Oguz; Uslu, Nihal; Baskin, Esra; https://orcid.org/0000-0002-5739-6590; https://orcid.org/0000-0001-7955-5735; 34015895; ABF-7609-2022; AAR-9945-2020
    Background: As the coronavirus disease 2019 (COVID-19) outbreak continues to evolve, it is crucially important for pediatricians to be aware of the differences in demographic and clinical features between COVID-19 and influenza A and B infections. Purpose: This study analyzed and compared the clinical features and laboratory findings of COVID-19 and influenza A and B infections in children. Methods: This retrospective study evaluated the medical data of 206 pediatric COVID-19 and 411 pediatric seasonal influenza A or B patients. Results: COVID-19 patients were older than seasonal influenza patients (median [interquartile range], 7.75 [2-14] years vs. 4 [2-6] years). The frequency of fever and cough in COVID-19 patients was lower than that of seasonal influenza patients (80.6% vs. 94.4%, P<0.001 and 22.8 % vs. 71.5%, P<0.001, respectively). Ageusia (4.9%) and anosmia (3.4%) were present in only COVID-19 patients. Leukopenia, lymphopenia, and thrombocytopenia were encountered more frequently in influenza patients than in COVID-19 patients (22.1% vs. 8.5%, P=0.029; 17.6% vs. 5.6%, P=0.013; and 13.2% vs. 5.6%, P=0.048, respectively). Both groups showed significantly elevated monocyte levels in the complete blood count (70.4% vs. 69.9%, P=0.511). Major chest x-ray findings in COVID-19 patients included mild diffuse ground-glass opacity and right lower lobe infiltrates. There were no statistically significant intergroup differences in hospitalization or mortality rates; however, the intensive care unit admission rate was higher among COVID-19 patients (2.4% vs. 0.5%, P=0.045). Conclusion: In this study, pediatric COVID-19 patients showed a wide range of clinical presentations ranging from asymptomatic/mild to severe illness. We found no intergroup differences in hospitalization rates, oxygen requirements, or hospital length of stay; however, the intensive care unit admission rate was higher among COVID-19 patients.
