Kopsavilkums
2024. gadā tika publicēti jauni Fīniksas sepses kritēriji sepses indentificēšanai bērniem. Fīniksas sepses skalā iegūti 2 vai vairāk punkti norāda uz dzīvību apdraudošu respiratoru, kardiovaskulāru, koagulācijas vai nervu sistēmas orgānu disfunkciju bērniem ar aizdomām par vai apstiprinātu infekciju. Līdz ar to ir nepieciešams noteikt iekaisuma marķieri, kurš spēs radīt aizdomas par infekciju pēc iespējas agrīnāk. C-reaktīvā proteīna daudzums, salīdzinot ar interleikīna-6 līmeni, asins serumā palielinās vairākas stundas vēlāk, tādēļ palielināta IL-6 līmeņa noteikšana varētu paātrināt infekcijas agrīnu diagnostiku. Efektīvas ārstēšanas stratēģijas nodrošina iespēju uzsākt empīrisku terapiju agrīnāk, kas samazinātu hospitalizācijas laiku un ekonomisko slogu.
Pētījuma mērķis ir noteikt, kurš iekaisuma biomarķieris - CRP vai IL-6 - ir agrīnāks infekcijas indikators sepses pacientiem, un analizēt to saistību ar leikocitozi un hipertermiju.
Tika veikts retrospektīvs pētījums. No 117 hospitalizētiem pacientiem Bērnu klīniskās universitātes slimnīcā no 2017. līdz 2023. gadam, 102 pacienti tika iekļauti pētījumā. Iekļaušanas kritēriji – 1)CRP un IL-6 līmenis noteikts asinīs iestāšanās laikā, 2)Sepses vai septiska šoka diagnoze uzstādīta, iestājoties slimnīcā, 3)Vecums no 1 mēneša līdz 18 gadiem. Pacientu vitālie rādītāji un laboratorie rezultāti tika iegūti no elektronisko sistēmu Andromeda un ICCA izrakstiem. IBM SPSS programma tika izmantota statistikas analīzei.
Mainīgie neatbilda normālsadalījumam. Spīrmena Ro tests atklāja statistiski nozīmīgu, pozitīvu, vāju korelāciju starp CRP un IL-6 (Rho=0,228, p=0,021), kā arī starp IL-6 un hipertermiju (Rho=0,257, p=0,009). Lai gan attiecīgi 18%, 4% un 42% pacientiem tika novērots normāls CRP, IL-6 un leikocītu daudzums asinīs, Manna-Vitnija U tests neuzrādīja statistiski nozīmīgas atšķirības CRP un IL-6 līmeņa, leikocītu daudzuma un hipertermijas attiecība starp pacientiem, kuriem bija sepse vai septisks šoks pēc Fīniksas sepses skalas un tiem, kuriem nebija (p>0,05). Līdz pat 75,5% pacientu tika novērota sepses hiperdiagnostika, izmantojot 2005.gadā publicētos IPSKK kritērijus.
1.Iekaisuma marķieri CRP un IL-6 ir vienlīdz vērtīgi infekcijas indikatori, neuzrādot statistiski nozīmīgas atšķirības starp sepses un ne-sepses grupām. 2.CRP līmenis vāji korelē ar IL-6 līmeni, savukārt IL-6 vāji korelē ar hipertermiju. 3.Fīniksas sepses kritēriji ir precīzāki, un tos ir nepieciešams integrēt bērnu veselības aprūpē. 4.Fīniksas sepses kritēriji ir būtiski sepses un septiska šoka diagnostikā, taču reti tiek izmantoti, tāpēc pacientiem ar sepsi vai septisku šoku ir nepieciešams veikt asinsspiediena mērījumus un koagulācijas paneli asins analīzēs. 5.Sepse un septisks šoks biežāk skar bērnus pirmsskolas vecumā, meitenes, hospitalizācijas ilguma mediāna ir 16 dienas. 6.Turpmāki pētījumi pediatrijas jomā ir nepieciešami, lai izpētītu iekaisuma biomarķierus agrīnas sepses un septiska šoka prognozēšanā un diagnostikā.
In 2024 new Phoenix sepsis criteria for identifying sepsis in children was published. 2 or more points in the Phoenix sepsis score indicate potentially life-threatening organ dysfunction of the respiratory, cardiovascular, coagulation, or neurological systems in children with suspected or confirmed infection. Consequently, it is necessary to determine an inflammatory marker which can suspect infection earlier. CRP, compared to IL-6 levels in blood serum, rise several hours later, so elevated IL-6 level detection could potentially accelerate the early diagnosis of infection and thus sepsis. Effective testing strategies provide an opportunity to initiate empiric therapy earlier, which would reduce the time spent in the hospital and economic burden. The aim of this study is to determine which inflammatory marker –CRP or IL-6– is an earlier indicator of infection in sepsis or septic shock patients and analyze the association of inflammatory biomarkers with hyperthermia and leukocytosis. A retrospective study was conducted. Of 117 patients hospitalized in Children’s Clinical University Hospital from 2017 to 2023, 102 were included in research. Inclusion criteria – 1)CRP and IL-6 determined in blood sample upon admission to the hospital, 2)Sepsis or septic shock diagnosis established upon admission, 3)Age from one month to 18 years. Patient vital signs and laboratory results were retrieved form electronic health record systems. IBM SPSS was used for statistical analysis. None of the variables followed normal distribution. Spearman’s rho test showed statistically significant positive correlation between CRP and IL6 (Rho=0,228, p=0,021) as well as IL-6 and hyperthermia (Rho=0,257, p=0,009). 18%, 4% and 42% of patients had normal CRP, IL-6 levels and white blood cell count, respectively. Mann-Whitney U Test showed no statistically significant difference in the distribution of CRP and IL6 levels, leukocytosis and hyperthermia between patients who had sepsis according to Phoenix Sepsis Score and who did not (p>0,05). Up to 75,5% of patients were over diagnosed using the IPSCC 2005 criteria. 1.Inflammatory markers CRP and IL-6 are equally valuable infection indicators, showing no statistically significant differences between sepsis and non-sepsis groups. 2.CRP levels weakly correlate with IL-6 levels, and IL-6 weakly correlates with hyperthermia. 3.The Phoenix sepsis criteria are more accurate and should be integrated into pediatric healthcare. 4.The Phoenix sepsis criteria are crucial for the diagnosis of sepsis, but are rarely used. Therefore, for patients with sepsis or septic shock, it is necessary to perform blood pressure measurements and include the coagulation panel in blood tests. 5.Sepsis and septic shock more often affects preschool-aged children, girls and the median length of hospitalization is 16 days. 6.Further studies are needed to investigate inflammatory biomarkers for early prediction and diagnosis of sepsis and septic shock.
