OBJECTIVE To evaluate the impact of sublingual immunotherapy(SLIT)on the balance of Treg/Th17 cells and related cytokines in preschool children aged 3-6 years with allergic rhinitis(AR).METHODS Seventy preschool children aged 3-6 years with AR were divided into the SLIT group and the medication group,and their clinical data were retrospectively analyzed.The medication group received symptomatic treatment alone,while the SLIT group received a combined treatment of SLIT and symptomatic medication,with a 3-year follow-up period.The Treg/Th17 cell balance,serum levels of TGF-β,IL-10,IL-17,IL-21,as well as the total nasal symptom score(TNSS),total medication score(TMS),and visual analog scale(VAS)scores were compared before and after treatment between the two groups.RESULTS After 3 years of treatment,both groups showed significant improvements(P<0.05)in the percentages of CD4+CD25+Foxp3+Treg and CD4+IL-17+Th17 cells among CD4+T cells,percentages of Treg and Th17 cells,serum levels of TGF-β,IL-10,IL-17,IL-21,TNSS,TMS,and VAS scores.Moreover,the SLIT group exhibited significantly better outcomes compared to the medication group(P<0.05).CONCLUSION SLIT can modulate the balance of Treg/Th17 cells and improve serum levels of TGF-β,IL-10,IL-17,and IL-21.
Résumé
Objective It has been increasingly realized that perioperative nutritional support plays an important role in improving clinical outcomes in children with congenital heart disease ( CHD) undergoing cardiopulmonary bypass surgery.The purpose of this review was to examine the nutritional conditions in perioperative CHD children and the main problems in nutri-tional management in the cardiac intensive care unit ( CICU) , based on which further directions were proposed .We found that preoperative malnutrition is common .This limited research of energy and protein is further compounded by the complex meta-bolic alterations with hyper-metabolism, hyper-catabolism and hypo-anabolism in the early postoperative course.Knowledge a-bout energy and protein metabolism and requirements in post-CPB children remains much limited .The current nutritional rec-ommendations in the CICU are based on little evidence .Insufficient energy and protein supply to meet demands remains a norm in the immediate postoperative period .The commonly used predictive equations do not provide accurate estimate of energy re-quirement in individual patients during the highly dynamic postoperative course .Indirect calorimetry can provide the best esti-mate of energy requirements for CHD infants .Nitrogen balance is recommended to assess the minimal protein requirement . During the early postoperative period, daily measurements of resting energy expenditure using indirect calorimetry and nitrogen balance in each individual child are essential to optimize energy and protein supply to meet requirements .A paradigm should be shifted toward individualized nutrition prescription in the context of a specific CICU feeding algorithm .
