To the Editor,

Pediatric acute respiratory distress syndrome (PARDS) is an acute-onset and progressive hypoxic condition caused by direct injury to the lung (e.g., pneumonia and gastric aspiration) or indirect injury (e.g., sepsis, trauma and pancreatitis).1 Blood types were discovered in the early 1900s, and blood type system based on the presence or absence of specific antigens on the surface of red blood cells (RBC).2 The antigens of the ABO blood group system (referred to as A, B, and H) are complex carbohydrate molecules located on the erythrocyte cell surface. They are also highly expressed on the surface of various human cells and tissues including the epithelium, sensory neurons, platelets, and vascular endothelium. Several previous studies have shown that blood group antigens are closely related to infectious diseases, vascular diseases, autoimmune diseases, malignant tumors, and other diseases.3,4

Blood type A has been associated with increased risk of endothelial inflammation. Previous studies noticed that the a glycosyltransferase phenotype is associated with an increased risk of myocardial infarction and thrombotic events.5,6 In blood type A phenotype, the polymorphisms of glycosyltransferase may lead to increased risk of vascular diseases. These effects

of ABO glycosyltransferase activity on von Willebrand factor structure have been hypothesized in order to explain the association between ABO blood type and vascular diseases.7 It is not clear the relationship between the activity of the ABO glycosyltransferases and the development of ARDS. In one study, blood type A was found to be associated with increased risk of ARDS in critically ill patients with trauma and sepsis.8 We investigated total of 22 children (aged 1 month to 18 years old) diagnosed with PARDS and 11 of non-ARDS cases. Patients were fulfilled the Pediatric Acute Lung Injury Consensus Conference definition for PARDS and intubated.

While pneumonia (13 of 22 patients, 59.0%) was the most common pulmonary reason of PARDS, aspiration was seen in that of 3 (13.6%) cases. Trauma and sepsis were recorded in that of one (4.6%), and 5 (22.8%) patients, respectively as extrapulmonary causes. ABO blood type was determined by standard RBC typing performed for clinical purposes before the receipt of transfused blood products. The ABO blood type was collected from blood bank records, allowing patients to be classifed as blood type A, B, AB, and O. Blood type A, B, AB, and O were detected in 12, 5, 1 and 4 patients with ARDS, respectively. The degree of hypoxemia was noted as 2 mild, 5 moderate and 5 severe hypoxemia in PARDS children with blood type A. In our study, some variables, such as pneumonia Sema Yılmaz1, Özden Özgür Horoz2, Gizem Güngör3, Dinçer Yıldızdaş2

was mostly seen 8 (36.3%) of patients who had A blood type and showed 75% infiltration area of lung.

In the present study, we hypothesized that blood type A was associated with increased risk of ARDS in critically ill children.

The potential mediators may directly or indirectly have an effect of ABO blood type on ARDS. The relationship between ABO blood type and pathogenesis of ARDS should be analyzed before these results are accepted into clinical practice. Future studies are needed to explore the main role of blood type A in mediating ARDS risk.
