Almost a quarter of a millennium after the discovery of an acidic substance in sour milk by Swedish chemist Carl Wilhelm Scheele and more than 100 years after the demonstration of a tight connection between this lactic acid and tissue hypoxia in shock, we are still surrounded by false beliefs and misunderstandings regarding this fascinating molecule. Common perceptions of lactate, the conjugate base of lactic acid, as a plain waste product of anaerobic metabolism and a marker of cellular distress could not be further from the truth. Lactate is formed and utilized continuously by our cells, even under fully aerobic conditions, in large quantities, and although marked hyperlactatemia is always a red flag in our patients, not all these conditions are life-threatening and vice versa-not all critically ill patients have hyperlactatemia. Lactate also does not promote acidosis by itself; it is not toxic, nor is it a metabolic renegade. On the contrary, it has many beneficial properties, and an interpretation of hyperlactatemia might be trickier than we tend to think. The aim of this article is to debunk some of the deeply rooted myths regarding this fascinating molecule.

Komunitní pneumonie je akutní zánětlivé onemocnění plicního parenchymu vzniklé mimo zdravotnické zařízení nebo do 48 hodin od přijetí do nemocnice. I přes dostupnost kauzální antibiotické léčby se dle dat Světové zdravotnické organizace jedná o celosvětově nejčastější příčinu úmrtí z infekčních příčin. Přestože by se mohlo zdát, že léčba infekčních onemocnění dolních cest dýchacích je uzavřenou kapitolou, opak je pravdou. Diagnostický rámec pneumonie zahrnuje heterogenní skupinu pacientů, kteří svým individuálním fenotypem onemocnění vyžadují specifický terapeutický přístup. Kontroverzní otázkou posledních dvaceti let je především adjuvantní použití kortikosteroidů s cílem modulace imunitně ‐inflamatorního poškození plicního parenchymu u těžké komunitní pneumonie. Výsledky klinických studií a jejich metaanalýz jsou bohužel protichůdné. Poslední konsensus čtyř významných evropských odborných společností doporučuje podání kortikoidů pouze u pacientů se současně přítomným septickým šokem. Stanovisko však bylo vydáno před uveřejněním dosud největší studie (CAPE COD), která svými závěry kontrastuje s uvedeným doporučením a velmi pravděpodobně v dohledné době změní přísné vymezení kortikoidů u pacientů se závažnou komunitní pneumonií. Cílem tohoto sdělení je poskytnout krátký klinicky orientovaný přehled ve stále kontroverzním problému a nabídnout k další odborné diskuzi pohled našeho pracoviště do doby, než budou k dispozici nová data a doporučení relevantních odborných grémií.
Community-acquired pneumonia (CAP) is an acute inflammatory disease of the lung parenchyma acquired outside the healthcare facilities or within 48 hours after admission to the hospital. Despite the availability of antibiotics, pneumonia remains the leading cause of death from infectious causes, according to World Health Organization data. Although it might seem that the treatment of lower respiratory tract infections is a closed chapter in a medical textbooks, it is quite the opposite. Our perception of pneumonia as a unifying diagnosis comes with a burden of heterogeneity and we need to approach each patient individually, based on their disease-specific phenotype. The adjuvant use of corticosteroids to modulate and dampen inflammation-induced lung injury in severe community-acquired pneumonia has been a matter of debate for the last twenty years. Up until recently, clinical trials and meta-analyses yielded conflicting results. Therefore, the last consensus of four respected European societies, recommends using corticosteroids in patients with severe community-acquired pneumonia only if septic shock is present. Unfortunately, those guidelines had been released shortly before the largest trial ever conducted on this group of patients (CAPE COD), which indicated different conclusions. This will probably lead to a reevaluation of the current strict recommendations for the use of corticosteroids. The following text aims to provide a brief clinically-oriented review of this controversial topic and present a perspective of our intensive care unit for further discussion until we have new relevant data and subsequent guidelines.

PURPOSE: To assess long-term outcomes of restrictive versus standard intravenous (IV) fluid therapy in adult intensive care unit (ICU) patients with septic shock included in the European Conservative versus Liberal Approach to Fluid Therapy in Septic Shock in Intensive Care (CLASSIC) trial. METHODS: We conducted the pre-planned analyses of mortality, health-related quality of life (HRQoL) using EuroQol (EQ)-5D-5L index values and EQ visual analogue scale (VAS), and cognitive function using Mini Montreal Cognitive Assessment (Mini MoCA) test at 1 year. Deceased patients were assigned numerical zero for HRQoL as a state equal to death and zero for cognitive function outcomes as worst possible score, and we used multiple imputation for missing data on HRQoL and cognitive function. RESULTS: Among 1554 randomized patients, we obtained 1-year data on mortality in 97.9% of patients, HRQoL in 91.3%, and cognitive function in 86.3%. One-year mortality was 385/746 (51.3%) in the restrictive-fluid group versus 383/767 (49.9%) in the standard-fluid group, absolute risk difference 1.5%-points [99% confidence interval (CI) - 4.8 to 7.8]. Mean differences were 0.00 (99% CI - 0.06 to 0.05) for EQ-5D-5L index values, - 0.65 for EQ VAS (- 5.40 to 4.08), and - 0.14 for Mini MoCA (- 1.59 to 1.14) for the restrictive-fluid group versus the standard-fluid group. The results for survivors only were similar in both groups. CONCLUSIONS: Among adult ICU patients with septic shock, restrictive versus standard IV fluid therapy resulted in similar survival, HRQoL, and cognitive function at 1 year, but clinically important differences could not be ruled out.

Multimorbidita – současná přítomnost více chronických onemocnění – je u kriticky nemocných velmi častá. Její preva- lence je zhruba 40–85 % a trendově se dále zvyšuje. Určitá chronická onemocnění, jako např. diabetes mellitus, obezita, chronické onemocnění srdce, plic, jater či ledvin a malignity, jsou asociovány s vyšším rizikem rozvoje závažných akutních komplikací a tedy i případné potřeby intenzivní péče. Tento přehledový článek shrnuje a diskutuje vybraná specifika péče o multimorbidní kriticky nemocné.
Multimorbidity - the simultaneous presence of several chronic diseases - is very common in the critically ill patients. Its prevalence is roughly 40-85 % and continues to increase further. Certain chronic diseases such as diabetes, obesity, chronic heart, pulmonary, liver or kidney disease and malignancy are associated with higher risk of developing serious acute complications and therefore the possible need for intensive care. This review summarizes and discusses selected specifics of critical care for multimorbid patients.
BACKGROUND: Sepsis is a common worldwide health condition with high mortality. It is caused by a dysregulated immune response to the pathogen. Severe infections resulting in sepsis can be also determined by monitoring several bloodstream biomarkers, one of them being pro-hormone procalcitonin (PCT). PCT concentration in the bloodstream correlates well with sepsis and in severe cases increases up to a thousand times from the healthy physiological values in a short time. In this study, we developed a rapid technique for PCT detection by MALDI-TOF mass spectrometry, that uses in-situ enrichment directly on the specialized immuno MALDI chips that are utilized as MALDI plates. The method's ability to detect PCT was confirmed by comparing the results with LC-MS bottom-up workflow. The new method detects intact PCT by its m/z and uncovers its alternations in septic serum. METHODS: The MALDI chips used for the detection of PCT were prepared by ambient ion soft landing of anti-PCT antibody on an ITO glass slide. The chips were used for the development of the rapid MALDI-TOF MS method. A parallel method based on affinity enrichment on magnetic beads followed by LC-MS/MS data-dependent peptide microsequencing was used to prove PCT presence in the sample. All samples were also tested by ELISA to determine PCT concentration prior to analyzing them by mass spectrometry methods. RESULTS: The MALDI chip method was optimized using recombinant PCT spiked into the human serum. The PCT detection limit was 10 ng/mL. The optimized method was used to analyze 13 sera from patients suffering sepsis. The PCT results were confirmed by LC-MS/MS. The measurement of the intact PCT by the MALDI chip method revealed that sera of patients with severe sepsis have other forms of PCT present, which show post-processing of the primary sequence by cleavage of PCT, resulting in the formation of N and C termini fragments. CONCLUSIONS: Procalcitonin from human serum was successfully enriched and detected using immunoaffinity MALDI chips. The intact PCT was characterized in 13 septic patients. The method is more specific compared to non-MS-based immunoaffinity techniques and allows observation of different variants of PCT in septic patients.

Patients with preexisting metabolic disorders such as diabetes are at a higher risk of developing severe coronavirus disease 2019 (COVID-19). Mitochondrion, the very organelle that controls cellular metabolism, holds the key to understanding disease progression at the cellular level. Our current study aimed to understand how cellular metabolism contributes to COVID-19 outcomes. Metacore pathway enrichment analyses on differentially expressed genes (encoded by both mitochondrial and nuclear deoxyribonucleic acid (DNA)) involved in cellular metabolism, regulation of mitochondrial respiration and organization, and apoptosis, was performed on RNA sequencing (RNASeq) data from blood samples collected from healthy controls and patients with mild/moderate or severe COVID-19. Genes from the enriched pathways were analyzed by network analysis to uncover interactions among them and up- or downstream genes within each pathway. Compared to the mild/moderate COVID-19, the upregulation of a myriad of growth factor and cell cycle signaling pathways, with concomitant downregulation of interferon signaling pathways, were observed in the severe group. Matrix metallopeptidase 9 (MMP9) was found in five of the top 10 upregulated pathways, indicating its potential as therapeutic target against COVID-19. In summary, our data demonstrates aberrant activation of endocrine signaling in severe COVID-19, and its implication in immune and metabolic dysfunction.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infected individuals display a wide spectrum of disease severity, as defined by the World Health Organization (WHO). One of the main factors underlying this heterogeneity is the host immune response, with severe COVID-19 often associated with a hyperinflammatory state. AIM: Our current study aimed to pinpoint the specific genes and pathways underlying differences in the disease spectrum and outcomes observed, through in-depth analyses of whole blood transcriptomics in a large cohort of COVID-19 participants. RESULTS: All WHO severity levels were well represented and mild and severe disease displaying distinct gene expression profiles. WHO severity levels 1-4 were grouped as mild disease, and signatures from these participants were different from those with WHO severity levels 6-9 classified as severe disease. Severity level 5 (moderate cases) presented a unique transitional gene signature between severity levels 2-4 (mild/moderate) and 6-9 (severe) and hence might represent the turning point for better or worse disease outcome. Gene expression changes are very distinct when comparing mild/moderate or severe cases to healthy controls. In particular, we demonstrated the hallmark down-regulation of adaptive immune response pathways and activation of neutrophil pathways in severe compared to mild/moderate cases, as well as activation of blood coagulation pathways. CONCLUSIONS: Our data revealed discrete gene signatures associated with mild, moderate, and severe COVID-19 identifying valuable candidates for future biomarker discovery.
