ABSTRACT
Cow's milk protein allergy (CMPA) is the most common type of food-allergy in younger children. Prognosis is usually good, with most children developing tolerance before school age. Children may present with a wide spectrum of symptoms that range from mild to severe; skin reactions such as angioedema and urticaria and gastrointestinal symptoms are the most common presentations of CMPA. Approximately one-third of CMPA patients suffer from multiple food-allergies; severe conditions such as anaphylactic shock (9%), eosinophilic esophagitis (4.7%), and food-protein induced enterocolitis (1%) may also develop in some children. Timely and accurate diagnosis and management is essential for proper growth and development of children with CMPA. In this expert consensus report, we aimed to adapt current understandings in the CMPA field to the specific conditions in Turkey and health system to help physicians with their day-to-day decision making

Background: Several pro-inflammatory and anti-inflammatory mediators play a role in the immunopathogenesis of food allergy (FA). The aim of this study was to investigate the utility of serum biomarkers like interleukin (IL)-10, TNF-alfa, and IL-6 in the diagnosis and/or follow-up of FA. Methods: Sixty (25 females, 41.6%) newly diagnosed FA patients [IgE mediated (group-1, n = 37), non-IgE (group-2, n = 23)] with a median age of nine (1-33) months were enrolled. Twenty-four healthy children with a median age of eight (1-36) months constituted the control group (CG). In all the subjects, serum TNF-alfa, IL-6 and IL-10 levels were evaluated at the time of diagnosis and reassessed four weeks after therapeutic elimination diet (TED). Results: The mean white blood cell count and median absolute eosinophile count of the CG were significantly lower than group-1 (p values were 0.019 and 0.006, respectively). The mean absolute neutrophile count and the median IL-6 were significantly higher in group-1 when compared with group-2 (p values were 0.005 and 0.032, respectively. Median TNF-alfa and IL-6 levels were significantly higher in the pre-TED among all patients (p values were 0.005 and 0.018, respectively). In group-1, median TNF-α and IL-6 levels decreased significantly after TED (p values were 0.01 and 0.029, respectively). Conclusions: Our findings support the role of inflammation in the pathogenesis of FA. Serum TNF-alfa and IL-6 levels may be useful markers for follow-up in FA, especially among IgE-mediated FA patients. Evaluation of IL-10 results was not sufficient for an interpretation of clinical tolerance
