Letter to the Editor Early enteral nutrition and optimization of the energy with supplemental parenteral nutrition Keywords: Critically-ill patients Enteral Parenteral Nutrition Supplemental Gut Dear Editor, Enteral nutrition is believed to preserve gut integrity, both structural and functional, through varied mechanisms including blood flow stimulation, induction of trophic endogenous agents and secretory IgA release, and retain of the intra-epithelial tight junctions and villous height. Adverse changes in gut permeability are parts of a dynamic time-dependent phenomenon whose conse- quences are but not limited to increased systemic infection and multi-organ dysfunction syndrome probability [1]. Yet, the most effective and easiest method for maintaining gut function is providing enteral nutrition as soon as possible. Some of the recently introduced approaches mention that there are only two options in feeding protocols for the critically-ill pa- tients: either to feed the patients at an escalating rate or keep them nil per os (NPO) [2]. One of the undesirable consequences of such strategies is that many patients who cannot tolerate the standard escalating rate of EN are kept NPO unnecessarily when a lower constant dose of EN can definitely be suitable. Based on 2009 ASPEN adult critical care guidelines, in critical ill patients unable to meet energy requirements (100% of target goal calories) after 7e10 days by the enteral route alone, we might consider initiating supplemental PN [3]. Hence, considering the fact that the gut plays a pivotal role in the critical illness and in or- der to maintain the gut integrity and functionality, whenever total energy requirements cannot be met form enteral route, it is logical to use PPN and reserve keeping NPO only for those in which there are contraindications for enteral nutrition. Calorie deficit is accom- panied by poor outcome considering the fact that the difficulties in maintaining enteral nutrition could lead to hypocaloric feeding throughout the more critical first week of ICU admission [4].

Dear Editor,
Enteral nutrition is believed to preserve gut integrity, bothstructural and functional, through varied mechanisms includingblood flow stimulation, induction of trophic endogenous agentsand secretory IgA release, and retain of the intra-epithelial tightjunctions and villous height. Adverse changes in gut permeabilityare parts of a dynamic time-dependent phenomenonwhose conse-quences are but not limited to increased systemic infection andmulti-organ dysfunction syndrome probability [1]. Yet, the mosteffective and easiest method for maintaining gut function isproviding enteral nutrition as soon as possible.
Some of the recently introduced approaches mention that thereare only two options in feeding protocols for the critically-ill pa-tients: either to feed the patients at an escalating rate or keepthem nil per os (NPO) [2]. One of the undesirable consequencesof such strategies is that many patients who cannot tolerate thestandard escalating rate of EN are kept NPO unnecessarily when alower constant dose of EN can definitely be suitable.
Based on 2009 ASPEN adult critical care guidelines, in critical illpatients unable to meet energy requirements (100% of target goalcalories) after 7e10 days by the enteral route alone, we mightconsider initiating supplemental PN [3]. Hence, considering thefact that the gut plays a pivotal role in the critical illness and in or-der to maintain the gut integrity and functionality, whenever totalenergy requirements cannot be met form enteral route, it is logicalto use PPN and reserve keeping NPO only for those in which thereare contraindications for enteral nutrition.
