INTRODUCTION: Ionised hypocalcemia (S-Ca2+) has been repeatedly observed in neonates with sepsis. Our aim was to evaluate total calcemia (S-Ca) and its relationship to laboratory markers of infection. METHODS: We retrospectively evaluated total calcemia (S-Ca) and its relationship to laboratory markers of sepsis/infection (serum levels of C-reactive protein - S-CRP and procalcitonin - S-PCT) in 29 full-term neonates with early-onset neonatal infection hospitalized at our neonatology ward between 2012 and 2016. The control group consisted of 705 neonates without infection. RESULTS: In neonates with early-onset infection , the S-Ca on day 1, 2 and 3 was significantly lower (p < 0.0001; p < 0.0001; p = 0.05 versus controls) same as the pooled S-Ca (p < 0.0001 versus controls). There was a weak negative correlation between pooled S-Ca and S-PCT, or pooled S-Ca and S-CRP (r = -0.22, p = 0.06; r = -0.19, p = 0.09). CONCLUSION: S-Ca was decreased in neonates with early-onset infection and did show a slight tendency to inverse correlation with S-CRP and S-PCT. Pediatricians must be aware of the fact that a drop in total S-Ca should alert their attention to the risk of neonatal infection, and, likewise, that the children with neonatal infection are at a higher risk of hypocalcemia with all its consequences.

Cíl studie: Sledování kinetiky calprotectinu a calgranulinu C v krvi u polytraumatizovaných pacientů, posouzení sérových koncentrací obou proteinů jako prediktorů nozokomiální infekce a srovnání sérových koncentrací calprotectinu a calgranulinu C s rutinními prozánětovými faktory a skórovacími systémy. Typ pracoviště: Pracoviště intenzivní medicíny fakultní nemocnice. Typ studie: Monocentrická prospektivní studie. Materiál a metoda: Do studie bylo zařazeno 25 pacientů s polytraumatem a 20 zdravých dobrovolníků. Pacientům byla odebrána krev při příjmu (1. den) a 3., 5. a 7. den hospitalizace a byla stanovena sérová koncentrace calprotectinu a calgranulinu C enzymoimunoanalyticky. Pacienti byli skórováni dle Injury Severity Score, Acute Physiology And Chronic Health Evaluation II a Sequential Organ Failure Assessment Score (SOFA). Z rutinních laboratorních parametrů byl stanoven počet leukocytů, C-reaktivní protein (CRP), prokalcitonin (PCT), glykemie, laktát. Dále byl sledován případný rozvoj nozokomiální infekce. Výsledky: U polytraumatizovaných pacientů byly zjištěny signifikantní elevace sérové koncentrace calprotectinu a calgranulinu C oproti zdravým kontrolám po celou dobu sledování. Dále byla zjištěna pozitivní korelace mezi oběma proteiny a SOFA skóre 1. a 3. den hospitalizace. Calprotectin a calgranulin C pozitivně korelovaly 3. den s CRP a PCT a calprotectin koreloval s CRP i 5. den studie. Patrný byl trend nižší koncentrace calprotectinu a calgranulinu C u 10 pacientů s nozokomiální infekcí a u těchto nemocných byla pozorována 1., 3. a 5. den signifikantně vyšší glykemie oproti pacientům bez infekční komplikace (n = 8). Závěr: Výsledky naznačují využití sérových koncentrací calprotectinu a calgranulinu C jako potencionálních biomarkerů polytraumatu.
Objective: To study the kinetics of calprotectin and calgranulin C in the serum of patients with polytrauma, to evaluate the serum levels of both the proteins as predictors of nosocomial infection (NI), and to compare calprotectin and calgranulin C with routine biomarkers and scoring systems. Design: Monocentric, prospective, clinical study Setting: University Hospital ICU Materials and methods: The study included 25 polytrauma patients and 20 healthy volunteers. The blood specimens were collected on admission (day 1) and then on days 3, 5 and 7 of hospitalization. Concentrations of calprotectin and calgranulin C were determined by enzyme immunometric assay. Patients were scored with Injury Severity Score, Acute Physiology And Chronic Health Evaluation II a Sequential Organ Failure Assessment Score (SOFA). The white blood cell count and the serum concentrations of the C-reactive protein (CRP), procalcitonin (PCT), glucose and lactate were the measured routine biomarkers. Other parameters included length of ICU stay, duration of mechanical ventilation, antibiotic therapy and development of nosocomial infection. Results: Significant elevations of the calprotectin and calgranulin C serum levels in trauma patients in comparison to healthy subjects were observed during the whole study period. Concentrations of both the proteins correlated positively with the SOFA score on days 1 and 3, CRP and PCT on day 3; and calprotectin also correlated with CRP on day 5. A trend of low serum levels of calprotectin a calgranulin C was observed in patients with nosocomial infection (n=10). In addition, these patients had significantly higher glycaemia on days 1, 3 and 5 in comparison to patients without infectious complication (n=8). Conclusions: The results suggest calprotectin and calgranulin C serum levels as suitable biomarkers of severe injury.

BACKGROUND: Infectious complications (IC) are one of the main causes of worsening prognosis after long-term ventricular assist device (LVAD) implantation. Procalcitonin (PCT) is widely used for diagnosis of a bacterial infection. The objective of this study was to assess PCT dynamics after LVAD surgery and their relationship to the infectious complications. METHODS: A total of 25 consecutive patients indicated for LVAD implantation as a bridge to heart transplant were included. Procalcitonin levels were prospectively assessed before surgery and during the postoperative period (day 1, 2, 14 and 30). Values were compared according to the presence of IC. RESULTS: Procalcitonin levels were low before surgery, raised significantly within 1st and 2nd day after operation and decreased in the 14th and 30th days back to the baseline. There was no significant difference in PCT values between patients with or without IC as well as with or without right ventricle assist device (RVAD). Acute renal failure (ARF) increased PCT significantly only 14 days after LVAD implantation. In patients with ARF and/or RVAD we observed significantly higher PCT values in the 2nd, 14thand 30thday after operation. In subjects with IC and/or ARF and/or RVAD we also observed significantly elevated PCT concentrations 2 and 14 days after surgery. CONCLUSIONS: Our data show that the ability of PCT to detect IC in patients after LVAD implantation is limited and its concentrations more likely correlate with postoperative complications in general.

Navzdory obrovskému pokroku v neonatologické péči, a to především v péči o nezralé novorozence, zůstává stále velkým problémem novorozenecká sepse. Novorozeneckou sepsi dělíme na časnou, tzv. „early-onset sepsis“, a pozdní, tzv. „late-onset sepsis“. V tomto přehledovém článku se zaměřujeme především na novorozeneckou sepsi časnou. Včasná diagnostika a zahájení terapie rozhoduje zásadním způsobem o dalším osudu dítěte. Klasická definice sepse se opírá o klinické známky a průkaz patogenu. V klinické praxi je to však problematické, a jsou tedy používány také pomocné laboratorní znaky bakteriální infekce. V přehledu uvádíme stručné informace o běžně užívaných laboratorních znacích. Druhou část sdělení věnujeme novým možnostem diagnostiky, konkrétně vyšetření sérového kalprotektinu a CD64 – povrchovému markeru leukocytů.
Despite the huge progress in neonatology, especially in care of premature infants, newborn sepsis remains a big problem.In neonatology, we talk about early-onset newborn sepsis and late-onset newborn sepsis. This review is focused on early-onsetsepsis. Early diagnosis and initiation of therapy is essential for infant`s good prognosis. Classic definition of sepsis is based onthe clinical signs and proof of pathogen in the blood stream. But, this is problematic in clinical practice, so another laboratorymar kers of bacterial infection are used. In this review article, we discuss commonly used markers. In the second part of thisarticle we introduce new diagnostic possibilities, especially new laboratory markers – calprotectin and CD64 (surface markerof leukocytes).

BACKGROUND: Up to 7% of term and late-preterm neonates in high-income countries receive antibiotics during the first 3 days of life because of suspected early-onset sepsis. The prevalence of culture-proven early-onset sepsis is 0·1% or less in high-income countries, suggesting substantial overtreatment. We assess whether procalcitonin-guided decision making for suspected early-onset sepsis can safely reduce the duration of antibiotic treatment. METHODS: We did this randomised controlled intervention trial in Dutch (n=11), Swiss (n=4), Canadian (n=2), and Czech (n=1) hospitals. Neonates of gestational age 34 weeks or older, with suspected early-onset sepsis requiring antibiotic treatment were stratified into four risk categories by their treating physicians and randomly assigned [1:1] using a computer-generated list stratified per centre to procalcitonin-guided decision making or standard care-based antibiotic treatment. Neonates who underwent surgery within the first week of life or had major congenital malformations that would have required hospital admission were excluded. Only principal investigators were masked for group assignment. Co-primary outcomes were non-inferiority for re-infection or death in the first month of life (margin 2·0%) and superiority for duration of antibiotic therapy. Intention-to-treat and per-protocol analyses were done. This trial was registered with ClinicalTrials.gov, number NCT00854932. FINDINGS: Between May 21, 2009, and Feb 14, 2015, we screened 2440 neonates with suspected early-onset sepsis. 622 infants were excluded due to lack of parental consent, 93 were ineligible for reasons unknown (68), congenital malformation (22), or surgery in the first week of life (3). 14 neonates were excluded as 100% data monitoring or retrieval was not feasible, and one neonate was excluded because their procalcitonin measurements could not be taken. 1710 neonates were enrolled and randomly assigned to either procalcitonin-guided therapy (n=866) or standard therapy (n=844). 1408 neonates underwent per-protocol analysis (745 in the procalcitonin group and 663 standard group). For the procalcitonin group, the duration of antibiotic therapy was reduced (intention to treat: 55·1 vs 65·0 h, p<0·0001; per protocol: 51·8 vs 64·0 h; p<0·0001). No sepsis-related deaths occurred, and 9 (<1%) of 1710 neonates had possible re-infection. The risk difference for non-inferiority was 0·1% (95% CI -4·6 to 4·8) in the intention-to-treat analysis (5 [0·6%] of 866 neonates in the procalcitonin group vs 4 [0·5%] of 844 neonates in the standard group) and 0·1% (-5·2 to 5·3) in the per-protocol analysis (5 [0·7%] of 745 neonates in the procalcitonin group vs 4 [0·6%] of 663 neonates in the standard group). INTERPRETATION: Procalcitonin-guided decision making was superior to standard care in reducing antibiotic therapy in neonates with suspected early-onset sepsis. Non-inferiority for re-infection or death could not be shown due to the low occurrence of re-infections and absence of study-related death.

Double balloon enteroscopy (DBE) was introduced 15 years ago. The complications of diagnostic DBE are rare, acute pancreatitis is most redoubtable one (incidence about 0.3%). Hyperamylasemia after DBE seems to be a rather common condition respectively. The most probable cause seems to be a mechanical straining of the pancreas. We tried to identify patients in a higher risk of acute pancreatitis after DBE. We investigated several laboratory markers before and after DBE (serum cathepsin B, lactoferrin, E-selectin, SPINK 1, procalcitonin, S100 proteins, alfa-1-antitrypsin, hs-CRP, malondialdehyde, serum and urine amylase and serum lipase). Serum amylase and lipase rose significantly with the maximum 4 hours after DBE. Serum cathepsin and procalcitonin decreased significantly 4 hours after DBE compared to healthy controls and patients values before DBE. Either serum amylase or lipase 4 hours after DBE did not correlate with any markers before DBE. There was a trend for an association between the number of push-and-pull cycles and procalcitonin and urine amylase 4 hours after DBE; between procalcitonin and alfa-1-antitrypsin, cathepsin and hs-CRP; and between E-selectin and malondialdehyde 4 hours after DBE. We found no laboratory markers determinative in advance those patients in a higher risk of acute pancreatitis after DBE.
