    Multisystem inflammatory syndrome (MIS-C) in children is a rare complication of SARS-CoV-2 infection. Knowing the course of the affected or unaffected coronary arteries in the patients under follow-up is important in terms of defining the long-term prognosis of the disease and determining the follow-up plan. This is a multicenter and retrospective study. The data were obtained from nine different centers. Between May 2020 and August 2022, 68 of 790 patients had coronary artery involvement. One-year echocardiographic data of 67 of 789 MIS-C patients with coronary artery involvement were analyzed. Existing pathologies of the coronary arteries were grouped as increased echogenicity, dilatation and aneurysm according to Z scores, and their changes over a 1-year period were determined. The data of all three groups are defined as frequency. SPSS Statistics version 22 was used to evaluate the data. In our study, aneurysm was observed in 16.4%, dilatation in 68.7% and increased echogenicity in 13.4% of the patients. All of the patients with involvement in the form of increased echogenicity recovered without sequelae by the end of the first month. No progression to aneurysm was observed in any of the patients with dilatation. No new-onset involvement was observed in patients with previously healthy coronary arteries during the convalescent period. In addition, from the sixth month follow-up period, there was no worsening in the amount of dilatation in any of the patients. At least 94% of the patients who completed the 12th month control period returned to normal.

    Vitamin D levels in children presenting with breath-holding spells: An example of a university hospital
    (2023) İpek, Rojan; Varan, Celal; 0000-0002-5636-0262; 0000-0002-3875-214X
    Aim: This study aimed to examine the vitamin D levels in children who experience breath-holding spells (BHS) and to compare these levels with those of a healthy control group. The goal was to establish a connection between BHS and vitamin D levels. Method: The records of 98 patients, who presented to the Pediatric Neurology and Pediatric Cardiology polyclinics of Adıyaman University Training and Research Hospital between December 2019 and October 2022, were retrospectively reviewed. Fifty-two patients who did not meet the inclusion criteria were excluded. The study included forty-six patients with BHS whose laboratory results were assessed and a healthy control group of fifty-three individuals. Fe, serum iron binding capacity, ferritin, vitamin B12, and vitamin D levels were measured in all patients. Results: The study group comprised 46 patients (female/male ratio = 1.4), consisting of 27 girls (58.6%) and 19 boys (41.3%). Within our patient cohort, 39 individuals (84.8%) were diagnosed with cyanotic-type spells, three (6.5%) with pallid-type spells, and four (8.7%) with mixed-type spells. For patients experiencing BHS, a comprehensive analysis was conducted on parameters including complete blood count, iron levels, iron-binding capacity, ferritin levels, vitamin B12, and vitamin D levels. Although no significant correlation was identified with vitamin D levels in this study, noteworthy connections were established with lower hemoglobin levels, decreased vitamin B12 levels, and reduced ferritin levels. Moreover, upon exclusion of patients exhibiting low vitamin B12 values from the analysis, a statistically significant relationship emerged between iron deficiency anemia and the occurrence of BHS (p<0.05). Conclusion: The study results suggest no significant correlation between low vitamin D levels and BHS, which generally have a favorable prognosis. However, considering the potential connections between iron deficiency anemia and vitamin B2 levels, it is advisable to assess these factors routinely.
