Abstract
Background and objectives: Acute myeloid leukemia (AML) is a malignancy that involves the bone marrow and peripheral blood. Some chemokines play a role in the progression, migration and tumor initiation and are therefore associated with poor prognosis. CCL2 promotes tumor growth and is associated with poor prognosis in AML patients. We investigated effects of chemotherapy on serum level of CCL2 in AML patients.
Methods: Throughout this case-control study, blood samples were collected from 25 healthy individuals and 25 AML (M4 and M5) patients before and after the first stage of the current chemotherapy regimen (7+3). Serum level of CCL2 was measured using commercial ELISA kits. Data were analyzed in SPSS 22 using the two-sample t-test and paired t-test.
Results: Before chemotherapy, serum level of CCL2 was significantly higher in the patients than in the healthy controls. Following chemotherapy, the serum level of CCL2 reduced significantly to a level comparable to that of the healthy controls.
Conclusion: The current chemotherapy (7+3) can effectively inhibit CCL2 in AML patients.

Abstract
Background: Atopic dermatitis (AD) is a common allergic disorder. Detection of responsible pathogenic allergens in AD patients by reliable methods has a fundamental role in the prevention, management, and treatment of AD. This study was conducted to determine the most common allergens by the skin prick test (SPT) and immunoblotting among AD patients referring to an allergy clinic in Birjand City, Iran.
Methods: The presence of AD was confirmed by an expert allergist. Serum levels of total and specific immunoglobulin E (sIgE) against 30 food and inhalant allergens were evaluated by a commercial immunoblotting kit (AlleisaScreen).
Results: The skin prick test was performed by a battery of 17 allergens. In total, 34 AD patients (mean age, 28.76 ± 17.36 years; range, 1-60 years; F/M ratio: 0.88) were enrolled in this study. The sensitization rates to at least 1 fungus, pollen, food, or indoor allergen by the immunoblotting method were 32.35%, 61.76%, 52.94%, and 47.05%, respectively. The most prevalent allergens were ragweed (52.94), Olive tree (41.16), Eucalyptus (35.29), date palm (35.29), and grass mix (32.28).
Conclusion: The study found that 85.29% of the studied population were sensitized to at least 1 allergen. Pollens and date palms were the most common allergens among AD patients, but the pattern of sensitization in SPT and immunoblotting was not exactly similar. Detection of allergens to which patients are sensitized and avoidance can help in the management of the disease and its symptoms.
