Hematologic Findings of Inherited Metabolic Disease: They are More Than Expected

Inherited metabolic diseases are pathologic conditions that generally develop as a result of impairment of the production or breakdown of protein, carbohydrate, and fatty acids. Early determination of hematological findings has a positive effect on the prognosis of metabolic diseases. Three hundred eighteen patients who were being followed-up within the previous 6 months at Department of Pediatric Nutrition and Metabolism, Gazi University, Turkey, were included in the study. The hematological findings were classified under 7 main groups: anemia of chronic disease, iron deficiency anemia, vitamin B12 deficiency anemia, hemophagocytosis, leukocytosis, and thrombocytosis. Nine hundred twenty-two hematological examinations of the 319 patients were included in the study, and 283 hematological findings were determined, 127 anemia of chronic disease, 81 iron deficiency anemia, 56 cytopenia, and 4 vitamin B12 deficiency anemia. Leukocytosis (n=1), thrombocytosis (n=5), and hemophagocytosis (n=9) were also observed. It was determined that, although anemia of chronic disease and nutritional anemia are the most common hematological findings, these may be diagnosed late, whereas neutropenia, thrombocytopenia, pancytopenia, and hemostasis disorders may be diagnosed earlier. Our study is the most comprehensive one in the literature, and we think it would positively contribute to the monitoring and prognosis of congenital metabolic diseases.

Long-term efficacy of lipoprotein apheresis in the management of familial hypercholesterolaemia: Application of two different apheresis techniques in childhood

Lipoprotein apheresis is used to treat patients with familial hypercholesterolemia (FH). The aim of the present study is to clarify the lipoprotein apheresis procedure performed by cascade filtration (CF) or double filtration plasmapheresis (DFPP) on pediatric patients in terms of side effects, laboratory results and cardiovascular follow-up. Data of ten pediatric patients were analyzed retrospectively. The average age of the patients was 12.1 ± 3.4 years. Percentage of long term reduction of low density lipoprotein cholesterol was 62.35 ± 7.19% (n = 3) for CF and 63.66 ± 6.63% (n = 3) for CF plus DFPP, 64.79 ± 8.29% (n = 7) for DFPP. Cardiovascular disease was not detected in thirty percent of the patients. Lesions remained stable in fifty percent of patients with heart valve lesions. Valvular lesions worsened in twenty percent of patients. Lipoprotein apheresis can be used effectively and successfully in pediatric patients as well as adults for homozygous FH.
