ABSTRACT

BACKGROUND: We aimed to evaluate the complications that we observed in children with acute lymphoblastic leukemia (ALL) during the remission induction, consolidation, and reinduction phases of chemotherapy retrospectively. METHODS: We analysed the clinical records of 128 patients with ALL who were diagnosed and treated in the Department of Pediatric Hematology of Istanbul Medeniyet University Goztepe Training Hospital between August 2009 and April 2014 to document the acute complication other than febrile neutropenia episodes, which developed during the induction, consolidation and reinduction phases of chemotherapy. RESULTS: We documented 279 complications. Of these, 53.05% were in males, 46.95% in females; 32.26% were in standard-risk, 45.52% in medium-risk, 22.22% in high-risk group of patients. Common documented events were pneumonia (25%), therapy-induced hyperglycemia (16.40%) therapy-related hepatitis (15.6%), generalized tonic-clonic seizures (14.8%), anaphylaxis to asparaginase (14.1%), hypertension (13.3%) varicella zoster virus (VZV) infection (13.3%), renal tubulopathy (12.5%). Time of complications was induction phase in 32.62%, consolidation in 19.35%, HR blocks in 18.28%, reinduction 29.75% during the phases. Mortality rate due to complications was 13.28%. CONCLUSIONS: Therapy-related complications can limit the survival rates in children with ALL. To minimize the treatment burden, even very rare complications must be considered and treated promptly with a multidisciplinary approach.

ABSTRACT

Mean platelet volume (MPV) and platelet distribution width (PDW) can help diagnose cardiovascular pathologies. In this study, we aimed to demonstrate the changes in platelet (PLT) indices in children diagnosed with bicuspid aortic valve (BAV) with mild stenosis and without stenosis to compare patients with mild stenosis with those without stenosis. A total of 73 children diagnosed with BAV (30 patients with mild stenosis and 43 without stenosis) with a mean age 9.73 ± 5.01 years and a control group were included in the study. Mean MPV value was significantly lower in the control group compared with patients with BAV with mild stenosis and patients without stenosis (p = 0.001, and p < 0.01, respectively). MPV was significantly greater in patients with mild stenosis than in patients without stenosis (p = 0.049 and p < 0.05, respectively). Patients with mild stenosis had a significantly greater mean PDW value compared with patients without stenosis and the control group (p = 0.024 and p < 0.05, respectively). There was no significant difference between patients without stenosis and the control group with respect to mean PDW value (p > 0.05). In conclusion, the results of this study demonsrate that children with BAV either with or without stenosis have increased MPV; the ones with mild stenosis have even greater values than the ones without stenosis. It emphasizes the risk of thrombosis in children with BAV.
