Idiopathic pulmonary hemosiderosis mimicking iron deficiency anemia: a delayed diagnosis?

Idiopathic pulmonary hemosiderosis (IPH) is an uncommon chronic disorder in children. It is characterized by recurrent pulmonary hemorrhage and may result in hemoptysis and pulmonary insufficiency. The most common hematologic manifestation of IPH is iron deficiency anemia. The etiology of IPH is not known and its diagnosis may be difficult due to the variable clinical courses. The most helpful signs for identifying IPH are iron deficiency anemia and recurrent or chronic cough, hemoptysis, dyspnea, wheezing. We report here 5 pediatric cases of IPH presenting with iron deficiency anemia and without pulmonary symptoms. Mean corpuscular volume was low in all patients; iron was low in 4 out of 5 cases; total iron binding capacity was high in all of them; ferritin was low in 3 patients. At follow up, none of them had responded successfully to the iron therapy. Although they didn’t present with pulmonary symptoms, chest radiographs incidentally revealed diffuse reticulonoduler shadows in all of them. Computed tomography revealed diffuse ground-glass opacities, consolidation, increased density. The diagnosis was confirmed by the detection of hemosiderinladen macrophages in bronchoalveolar lavage fluid and gastric aspirate. If patients with iron deficiency anemia don’t respond to iron therapy, they should be examined for IPH. Chest radiographs should be taken even in absence of pulmonary symptoms. Early diagnosis is important for a timely management of IPH

Successful Management of L-Asparaginase-Associated Pancreatitis With Octreotide and Pegylated Asparaginase in 2 Patients With Acute Lymphoblastic Leukemia: Is There a Different Rare Warning Sign of Hypoglycemia for L-Asparaginase-Associated Pancreatitis?

L-Asparaginase (L-Asp) is a critical component of chemotherapy for acute lymphoblastic leukemia (ALL). However, toxic effects associated with L-Asp, such as hepatic dysfunction, pancreatitis, hypercholesterolemia, and hyperglycemia, have occurred. In addition, acute pancreatitis is a significant life-threatening adverse event associated with ALL. We describe 2 patients with ALL who had L-Asp-associated pancreatitis (AAP), with one patient presenting with hyperglycemia and the other presenting with hypoglycemia during induction treatment. When octreotide was administered to both of these patients, the clinical findings and laboratory data were improved. AAP was not repeated after treatment with pegylated asparaginase. Although AAP has a high risk of mortality and morbidity in childhood, APP treatment with appropriate agents, such as octreotide, can be successful. (C) 2020 Elsevier Inc

Late diagnosis of leukocyte adhesion deficiency type II and Bombay blood type in a child: A rare case report

Leukocyte adhesion deficiency type II (LAD II) is a rare, autosomal, recessive inherited immunodeficiency disease that induces frequent and recurrent infections, persistent leukocytosis, severe mental and growth retardation, and impaired wound healing. The Bombay blood group is a rare blood group phenotype that is characterised by the deficiency of H, A, and B antigens on the surface of red cells. LAD II and the Bombay blood group are always seen together, because both of them are associated with a global defect in the common pathway of fucose metabolism. Here we report the case of an 11-year-old boy with LAD II, who presented with the Bombay blood group. Agglutination with strength of 4+ was detected in all cross-matching due to erythrocyte transfusions for our patient. Therefore, the Bombay blood group was incidentally determined due to deficient expression of the CD15 adhesion molecules on the surface of the leukocytes according to the results of flow cytometry. Upon detecting the Bombay blood type, LAD II was then diagnosed as a result of flow cytometry and the clinical findings of mental retardation and history of recurrent infections such as abscesses

Refugee children with beta-thalassemia in Turkey: Overview of demographic, socioeconomic, and medical characteristics

Aim Since the beginning of the Syrian civil war, more than 3.5 million Syrians have been under temporary protection status in Turkey. Because beta-thalassemia (BT) is a prevalent disorder in the Mediterranean countries, we decided to estimate the prevalence of and make an overview of the demographic, socioeconomic, medical characteristics, and healthcare problems of refugee children with BT. Patients Eighteen Turkish Pediatric Hematology Oncology Centers (PHOC) with 318 refugee children from 235 families participated in the study. The mean age of the patients was 8.1 +/- 4.8 years (0.5-21 years). The mean time after immigration to Turkey was 2.5 +/- 1.5 years (range, 0.1-7 years). Seventy-two (22.6%) of them were born and diagnosed with BT in Turkey. On physical examination, 82 patients (26%) were underweight and 121 patients (38%) were stunted. The appearance of a thalassemic face was reported for 207 patients (65.1%). Hepatomegaly and splenomegaly were reported in 217 (68.2%) and 168 (52.8%) patients, respectively. The median ferritin level was 2508 ng/mL (range, 17-21 000 ng/mL) at the first admission, and 2841 ng/mL (range, 26-12 981 ng/mL) at the last visit after two years of follow-up in a PHOC (P > 0.05). The most frequently encountered mutation was IVSI-110 (G>A) (31%). Before immigration, only 177 patients (55.6%) reported the use of chelators; after immigration it increased to 268 (84.3%). Conclusion Difficulties in communication, finding a competent translator capable in medical terminology, nonregular use of medications, and insensitivity to prenatal diagnosis were preliminary problems. The current extent of migration poses emerging socioeconomic and humanitarian challenges for refugee patients with BT
