    Objective: Celiac disease (CD) is a systemic inflammatory disease associated with a number of hematological findings. The most common symptom other than the intestinal system is iron deficiency anemia (IDA). It is difficult to distinguish IDA that occurs in CD from nutritional IDA. In this study, the use of hematological parameters and leukocyte formulas, which are reported to be of diagnostic importance in inflammatory diseases, as a screening test in predicting CD in children with IDA was investigated. Methods: Forty-six children with CD and IDA, 46 children with nutritional IDA and 46 healthy children as a control group were included in the study. The patient files were examined retrospectively. The blood count parameters [Hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), mean platelet volume (MPV), platelet distribution width (PDW), erythrocyte, leukocyte, neutrophil, lymphocyte, platelet count] of the patients before starting iron therapy were recorded. Leukocyte formulas [neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), RDW/lymphocyte ratio (RLR)] were calculated. Results: There was no difference between the patient and control groups in terms of age and gender distribution (p>0.05). Hb, MCV, MCH, MCHC values of CD+IDA and IDA groups were lower than the values of the control group (p<0.001, for all), RDW, RLR, PLR values, and platelet count were higher than the values of the control group (p<0.001 and p<0.001; p<0.05 and p<0.01; p<0.05 and p<0.05; p<0.001 and p<0.05, respectively). Leukocyte, neutrophil, lymphocyte, erythrocyte counts, MPV, PDW, NLR were found to be similar in the patient and control groups (p>0.05 for all). There was no difference between the patient groups in terms of NLR, PLR, and RLR (p>0.05 for all). Conclusion: Our study showed that hematological parameters and leukocyte formulas are not useful in predicting CD in children with IDA.

    Tandem high-dose chemotherapy followed by autologous stem cell transplantation: An infant with trilateral retinoblastoma
    (Wiley, 2023) Toret, Ersin; Ozdemir, Zeynep Canan; Zengin Ersoy, Gizem; Oztunali, Cigdem; Bozkurt, Ceyhun; Kebudi, Rejin
    BackgroundRetinoblastoma (RB) is the most common intraocular malignancy in childhood. Advanced RB, associated with exceedingly poor prognosis, requires more intensive multiagent chemotherapy than conventional regimens. Rescue of the bone marrow after intensive chemotherapy is achieved with stem cell transplantation. The sequential courses (tandem transplantation) of high-dose chemotherapy followed by autologous stem cell transplantation allow for even greater dose intensity in consolidation with the potential to use different active chemotherapeutics at each transplant and have proven feasible and successful in treating children with recurrent/refractory solid tumors. Case DescriptionWe report an infant with trilateral high-risk RB who received tandem high-dose chemotherapy (HDC) followed by autologous stem cell transplantation after the conventional chemotherapy. A 5-month-old female patient presented with strabismus, and the ophthalmoscopic examination showed intraocular tumoral lesions in both eyes. Magnetic resonance imaging (MRI) concluded the trilateral retinoblastoma diagnosis due to a tumoral mass in the optic chiasm. The follow-up ophthalmologic examinations and the MRI detected stable disease after six cycles of multiagent chemotherapy. ConclusionsRescue with autologous stem cell transplantation after HDC allows for an increase in chemotherapy intensity. Tandem transplantation provides the chance to perform different chemotherapeutics at each transplant and enables an increase in the chemotherapy intensity, thus providing a positive effect on disease-free survival.
