Severity of illness was assessed on the basis of two scores which are used for routine assessment following patients’ admission to the PICUs: the paediatric logistic organ dysfunction (PELOD) score and the paediatric risk of mortality (PRISM) III score for the first 24<span class="elsevierStyleHsp" style=""></span>h following diagnosis.

Consistent to previous similar studies, the choice of timing of samples collection at days 1 and 7 was based on the fact that NK cells act both in innate and adaptive immune responses. During the rapid innate immune response, they act during the first few days by killing through apoptosis or antibody-dependent cell mediated cytotoxicity. Later on, NK cells start to proliferate and release IFN-γ and other cytokines such as IL-1 and GM-CSF that lead to activation of cell-mediated immune response of the adaptive immune system and this reaches its maximum starting at one week of infection.<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">17</span></a></p></li></ul></p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0075">Statistical analysis</span><p id="par0065" class="elsevierStylePara elsevierViewall">Collected data were entered and analysed using the Statistical Package for Social Science Software (SPSS) program, version 21.0 IBM.
