Neutrophils are frequently found in the cytological picture of synovial fluid in several joint pathologies, and a higher proportion of them can even wrongly indicate these cases as purulent inflammation. For reliable differentiation between purulent and non-purulent cases, we use the cytological energy analysis of the synovial fluid. Using this method, we examined 350 knee joint synovial fluid samples. Overall, we found that the percentage of neutrophils ranged between 20.0% and 50.0% in 44 (12.6%) cases and was above 50.0% in 231 (66.0%) cases. In the same group, only 85 (24.3%) highly anaerobic synovial fluid samples were evaluated as purulent inflammation, and another 17 (4.9%) cases were evaluated as very likely purulent inflammation. Further, we quantified the immediate risk of purulent inflammation using the "purulent score" (PS). Of the total of 350 samples, 103 (29.4%) cases were classified as having a very high risk of purulent inflammation (PS = 4), 53 (15.1%) cases were classified as having a significant risk of purulent inflammation (PS = 3), 17 (4.9%) cases were classified as having a moderate risk of purulent inflammation (PS = 2), and 75 (21.4%) cases were classified as having no immediate risk of purulent inflammation (PS = 1). Based on our results and analyses, the cytological energy analysis of synovial fluid is an effective method that can be used to detect and specify joint inflammation and the risk of septic arthritis development.

Laboratory analysis of basic cerebrospinal fluid (CSF) parameters is considered as essential for any CSF evaluation. It can provide rapidly very valuable information about the status of the central nervous system (CNS). Our retrospective study evaluated parameters of basic CSF analysis in cases of either infectious or non-infectious CNS involvement. Neutrophils are effector cells of innate immunity. Predominance of neutrophils was found in 98.2% of patients with purulent inflammation in CNS. Lymphocytes are cellular substrate of adaptive immunity. We found their predominance in 94.8% of patients with multiple sclerosis (MS), 66.7% of patients with tick-borne encephalitis (TBE), 92.2% of patients with neuroborreliosis, 83.3% of patients with inflammatory response with oxidative burst of macrophages in CNS and 75.0% of patients with malignant infiltration of meninges (MIM). The simultaneous assessment of aerobic and anaerobic metabolism in CSF using the coefficient of energy balance (KEB) allows us to specify the type of inflammation in CNS. We found predominantly aerobic metabolism (KEB > 28.0) in 100.0% CSF of patients with normal CSF findings and in 92.8% CSF of patients with MS. Predominant faintly anaerobic metabolism (28.0 > KEB > 20.0) in CSF was found in 71.8% patients with TBE and in 64.7% patients with neuroborreliosis. Strong anaerobic metabolism (KEB < 10.0) was found in the CSF of 99.1% patients with purulent inflammation, 100.0% patients with inflammatory response with oxidative burst of macrophages and in 80.6% patients with MIM. Joint evaluation of basic CSF parameters provides sufficient information about the immune response in the CSF compartment for rapid and reliable diagnosis of CNS involvement.

The simultaneous cytological and metabolic investigation of various extravascular body fluids (EBFs) provides clinically relevant information about the type and intensity of the immune response in particular organ systems. The oxidative burst of professional phagocytes with the concomitant production of reactive oxygen species consumes a large amount of oxygen and is the cause of switch to the development of anaerobic metabolism. We assessed the relationships between percentages of neutrophils, aerobic and anaerobic metabolism, and tissue damage via the determination of aspartate aminotransferase catalytic activities (AST) in cerebrospinal fluid (CSF), pleural effusions (PE), abdominal effusions (AE), and synovial fluids (SF). EBFs with 0.0-20.0% neutrophils: 83.0% aerobic and 1.3% strongly anaerobic cases with median of AST = 13.8 IU/L in CSF; 68.0% aerobic and 9.0% strongly anaerobic cases with median of AST = 20.4 IU/L in PE; 77.5% aerobic and 10.5% strongly anaerobic cases with median of AST = 18.0 IU/L in AE; 64.1% aerobic and 7.7% strongly anaerobic cases with median of AST = 13.8 IU/L in SF. EBFs with 80.0-100.0% neutrophils: 4.2% aerobic and 73.7% strongly anaerobic cases with median of AST = 19.2 IU/L in CSF; 7.4% aerobic and 77.3% strongly anaerobic cases with median of AST = 145.2 IU/L in PE; 11.8% aerobic and 73.7% strongly anaerobic cases with median of AST = 61.8 IU/L in AE; 25.5% aerobic and 38.2% strongly anaerobic cases with median of AST = 37.2 IU/L in SF. The significant presence of neutrophils, concomitant strong anaerobic metabolism, and elevated AST in various EBFs are reliable signs of damaging purulent inflammation.

Extravasation of blood in the central nervous system (CNS) represents a very strong damaged associated molecular patterns (DAMP) which is followed by rapid inflammation and can participate in worse outcome of patients. We analyzed cerebrospinal fluid (CSF) from 139 patients after the CNS hemorrhage. We compared 109 survivors (Glasgow Outcome Score (GOS) 5-3) and 30 patients with poor outcomes (GOS 2-1). Statistical evaluations were performed using the Wilcoxon signed-rank test and the Mann-Whitney U test. Almost the same numbers of erythrocytes in both subgroups appeared in days 0-3 (p = 0.927) and a significant increase in patients with GOS 2-1 in days 7-10 after the hemorrhage (p = 0.004) revealed persistence of extravascular blood in the CNS as an adverse factor. We assess 43.3% of patients with GOS 2-1 and only 27.5% of patients with GOS 5-3 with low values of the coefficient of energy balance (KEB < 15.0) in days 0-3 after the hemorrhage as a trend to immediate intensive inflammation in the CNS of patients with poor outcomes. We consider significantly higher concentration of total protein of patients with GOS 2-1 in days 0-3 after hemorrhage (p = 0.008) as the evidence of immediate simultaneously manifested intensive inflammation, swelling of the brain and elevation of intracranial pressure.

Materiál a metody: Náš soubor pro tuto studii zahrnuje 96 případů nezánětlivých pleurálních výpotků od pacientů s kardiálním postižením či systémovou sepsí, 211 případů pleurálních výpotků od pacientů s purulentní pneumonií a 283 případů pleurálních výpotků od pacientů s hrudním empyémem. Ve všech případech jsme provedli vyšetření vybraných parametrů dle Lightových pravidel (počet jaderných elementů na 1 μl, koncentrace celkové bílkoviny, glukózy a laktátu a katalytická aktivita laktátdehydrogenázy (LDH)) a kompletní cytologicko-energetickou analýzu (četnost neutrofilních granulocytů, výpočet koeficientu energetické bilance (KEB) a katalytická aktivita aspartátaminotrasferázy (AST)). Pro statistické zhodnocení souboru jsme použili Kruskal-Wallisův test s vícenásobným porovnáním p-hodnot a ROC analýzu. Výsledky: Na úrovni všech zmíněných parametrů dle Lightových kritérií i cytologicko-energetické analýzy nacházíme při porovnání nezánětlivých a zánětlivých výpotků statisticky významné rozdíly (p < 0,01). Při porovnání výpotků pacientů s purulentními pneumoniemi a hrudními empyémy nacházíme statisticky významné diference (p < 0,01) v případě „Lightových“ počtů jaderných elementů, koncentrací celkové bílkoviny a laktátu a katalytických aktivit LDH a „cytologicko-energetických“ hodnot KEB a katalytických aktivit AST. Pro rozlišení nezánětlivých a parapneumonických výpotků dosáhly vysokou diagnostickou efektivitu „Lightovy“ koncentrace glukózy (AUC = 0,981), laktátu (AUC = 0,970) a katalytické aktivity LDH (AUC = 0,962) a „cytologicko- energetické“ četnosti neutrofilních granulocytů (AUC = 0,982), hodnoty KEB (AUC = 0,999) a katalytické aktivity AST (AUC = 0,954).Pro rozlišení nezánětlivých výpotků a výpotků pacientů s hrudními empyémy dosáhly vysokou diagnostickou efektivitu „Lightovy“ počty jaderných elementů (AUC = 0,939), koncentrace glukózy (AUC = 0,967), laktátu (AUC = 0,987) a katalytické aktivity LDH (AUC = 0,984) a „cytologicko-energetické“ četnosti neutrofilních granulocytů (AUC = 0,985), hodnoty KEB (AUC = 0,991) a katalytické aktivity AST (AUC = 0,979). Podstatně nižších diagnostických efektivit všech sledovaných parametrů bylo dosaženo při diferenciaci parapneumonických výpotků a výpotků pacientů s hrudními empyémy: „Lightovy“ počty jaderných elementů (AUC = 0,714), koncentrace glukózy (AUC = 0,631), laktátu (AUC = 0,721), celkové bílkoviny (AUC = 0,537) a katalytických aktivit LDH (AUC = 0,710) a „cytologicko-energetické“ četnosti neutrofilních granulocytů (AUC = 0,553), hodnot KEB (AUC = 0,671) a katalytických aktivit AST (AUC = 0,718). Závěr: Předností cytologicko-energetické analýzy oproti analýze pleurálních výpotků dle Lightových kritérií je charakteristika lokální imunitní odpovědi s ohledem na její energetické nároky. Obě metodiky se vhodně doplňují. V žádném případě si ale neodporují.
Objective: Comparison of diagnostic efficiency of Light's parameters with cytological-energy analysis parameters of pleural effusion. Design: retrospective. Settings: Biomedical Centre, Krajská zdravotní, a. s. - Masaryk Hospital in Ústí nad Labem, o. z.; Department of Clinical Immunology and Allergology, Faculty of Medicine and University Hospital in Hradec Králové, Charles University in Prague; Laboratory for Cerebrospinal Fluid, Neuroimmunology, Pathology and Special Diagnostics Topelex, s.r.o; Department of Thoracic Surgery, Krajská zdravotní, a.s. - Masaryk Hospital in Usti nad Labem, o.z.; Department of Clinical Biochemistry, Krajská zdravotní, a.s. – Masaryk Hospital in Ústí nad Labem, o.z. Material and Methods: The 96 samples of noninflammatory pleural effusions of patients with cardiac failure or systemic sepsis, the 211 samples of pleural effusions of patients with purulent pneumonia and the 283 samples of pleural effusions of patients with chest empyema were analysed. In all cases, we analysed selected parameters of Light criteria (total number of nuclear elements in 1 μl, concentration of total protein, glucose, lactate and catalytic activity of lactate dehydrogenase (LDH)) and parameters of cytological-energy analysis (frequency of neutrophils, KEB value and catalytic activity of aspartate aminotransferase (AST)). Statistical analysis was performed using the ANOVA Kruskal-Wallis test and ROC-analysis. Results: We found significant differences of parameters of Light‘s criteria and cytological-energy analysis between inflammatory and noninflammatory pleural effusions (p < 0.01). We found significant differences between patients with purulent pneumonia and chest empyema (p < 0.01). Light's criteria parameters included total number of nuclear elements, concentration of total protein, lactate and catalytic activities of LDH. Cytological-energy parameters included KEB value and catalytic activities of AST. We found high diagnostic accuracy of ,,Light's‘‘ concentration of glucose (AUC = 0.981), lactate (AUC = 0.970) and catalytic activities of LDH (AUC = 0.962) and ,,cytological-energy‘‘ frequency of neutrophils (AUC = 0.982), KEB values (AUC = 0.999) and catalytic activities of AST (AUC = 0.954) to distinguish between noninflammatory and parapneumonic pleural effusions. We found high diagnostic accuracy of „Light's“ total number of nuclear elements (AUC = 0.939), concentration of glucose (AUC = 0.967), lactate (AUC = 0.987) and catalytic activities of LDH (AUC = 0.984) and ,,cytological-energy‘‘ frequency of neutrophils (AUC = 0.985), KEB values (AUC = 0.991) and catalytic activities of AST (AUC = 0.979) to distinguish between noninflammatory pleural effusions and pleural effusions of patients with chest empyema. We found low diagnostic accuracy of all parameters to distinguish parapneumonic effusion and pleural effusion of patients with chest empyema: „Light's“ total number nuclear elements (AUC = 0.714), concentration of glucose (AUC = 0.631), lactate (AUC = 0.721), total protein (AUC = 0.537) and catalytic activities of LDH (AUC = 0.710) and „cytological-energy‘‘ frequency of neutrophils (AUC = 0.553), KEB values (AUC = 0.671) and catalytic activities of AST (AUC = 0.718). Conclusion: The advantage of cytological-energy analysis versus Light's criteria parameters is in their abilities to characterize a local immune response considering the energy state. Both methods complement each other appropriately. In any case, they do not contradict each other.

Brain ischemia after central nervous system (CNS) bleeding significantly influences the final outcome of patients. Catalytic activities of aspartate aminotransferase (AST) in the cerebrospinal fluid (CSF) to detect brain ischemia were determined in this study. The principal aim of our study was to compare the dynamics of AST in 1956 CSF samples collected from 215 patients within a 3-week period after CNS hemorrhage. We compared concentrations of the AST catalytic activities in the CSF of two patient groups: survivors (Glasgow Outcome Score (GOS) 5-3) and patients in a vegetative state or dead (GOS 2-1). All statistical evaluations were performed using mixed models and the F-test adjusted by Kenward and Roger and the Bonferroni adjustment for multiple tests. The significantly higher catalytic activities of AST in the CSF from patients with the GOS of 2-1 when compared to those who survived (GOS 5-3, p = 0.001) were found immediately after CNS haemorrhage. In the further course of time, the difference even increased (p < 0.001). This study confirmed the key association between early signs of brain damage evidenced as an elevated AST activity and the prediction of the final patient's clinical outcome. The study showed that the level of AST in the CSF could be the relevant diagnostic biomarker of the presence and intensity of brain tissue damage.

BACKGROUND: The predominance of neutrophils in pleural effusions of patients with different serious impairments of the pleural cavity organs is often found. The aim of this study was to identify the type of injury using the cytological-energy analysis of pleural effusions. METHODS: We analysed 635 samples of pleural effusions with predominance of neutrophils. We compared the values of the coefficient of energy balance (KEB), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) catalytic activities in the following subgroups of patients: with transudative effusions, purulent pneumonia, chest empyema and after chest surgery with and without purulent complications. Statistical analysis was performed using the ANOVA Kruskal-Wallis test (p < 0.05 was considered as significant). RESULTS: We found the lowest KEB values in pleural effusions of patients with chest empyema and their gradual increases in patients with purulent pneumonia and with transudative effusions. We observed the highest LDH and AST enzymes activity in patients with chest empyema and their gradual decrease in patients with purulent pneumonia and with transudative effusions. LDH and AST enzymes activity was significantly higher in pleural effusions of patients after chest surgery with purulent complications compared with non-purulent cases. CONCLUSION: The most intensive inflammation and the most extensive tissue destruction in the pleural cavity were found in patients with chest empyema. Significantly better parameters were observed in patients with purulent pneumonia. The absence of serious inflammation and the absence of tissue destruction were typical for patients with transudative effusions. Finally, our results confirmed an anticipated higher tissue destruction in patients after chest surgery. Significantly worse injury was found in surgical patients with purulent complications compared with non-purulent ones. The reviews of this paper are available via the supplemental material section.

BACKGROUND: The concentrations of glucose and lactate in cerebrospinal fluid (CSF) provide important information about energy metabolism in the CSF compartment. To improve our understanding of this information we introduced a new parameter resulting from a formula for calculating the fictitious production of adenosine triphosphate, i.e., the coefficient of energy balance (KEB). METHODS: We evaluated cytology, the concentrations of glucose and lactate and the KEB in the CSF of 948 patients, who were divided into five groups. For statistical analysis we used the Kruskal-Wallis test with post-hoc analysis using the Dunn method and multinomial regression analysis. We determined the specificities and sensitivities of the cytological pictures and the KEB. RESULTS: A KEB>28.0 corresponded to normal energy metabolism in the CSF. A KEB<28.0 corresponded to an increased level of anaerobic metabolism in the CSF during inflammation in the CNS. A KEB<10.0 corresponded to a high level of anaerobic metabolism in the CSF during severe inflammation with an oxidative burst of professional phagocytes in the CNS. The KEB parameter increased the specificities of cytological examinations of the CSF in all cases. CONCLUSIONS: The KEB represents an equation for calculating the fictitious average number of ATP molecules produced in the CSF compartment from one molecule of glucose, and we used it successfully as a new parameter for evaluating energy metabolism status in the CSF.
Cíle studie: 1. Zhodnocení buněčností likvoru (CSF, z angl. cerebrospinal fluid = mozkomíšní mok), koncentrací glukózy v CSF, hodnot glukózového kvocientu (Q glu. ), koncentrací laktátu v CSF a hodnot koeficientu energetické bilance (KEB) coby ukazatelů intenzity zánětlivého procesu v centrálním nervovém systému (CNS) ve skupinách pacientů bez postižení CNS, pacientů s mírnými serózními záněty CNS neinfekční etiologie, pacientů se serózními záněty CNS infekční etiologie a pa- cientů s purulentními záněty CNS s extracelulárními bakteriemi v patogenezi. 2. Porovnání informačního potenciálu parametrů energetického metabolismu glukózy v likvorovém kompartmentu v soubo - ru vyšetřených pacientů, tzn. koncentrací glukózy v CSF, hodnot Q glu. , koncentrací laktátu v CSF a hodnot KEB. Typ studie: Retrospektivní studie. Materiál a metody: Vyšetřili jsme 133 vzorků CSF pacientů bez postižení CNS, 227 vzorků CSF pacientů s mírnými serózními záněty CNS s intrathekální syntézou imunoglobulinů neinfekční etiologie, 208 vzorků CSF pacientů se serózními záněty CNS infekční příčiny a 140 vzorků CSF pacientů s purulentními záněty CNS s extracelulárními bakteriemi v patogenezi. Oblastí našeho zájmu byly buněčnost CSF, koncentrace glukózy v CSF, hodnoty Q glu. , koncentrace laktátu v CSF a hodnoty KEB. Pro statistické hodnocení vybraných parametrů jsme použili D’Agostinův omnibus test, Kruskalův-Wallisův test s následnou post hoc analýzou Dunnovou metodou, Spearmanův korelační koeficient a multinomiální logistickou regresní analýzu. Výsledky: V likvorovém kompartmentu pacientů bez postižení CNS jsme nezjistili žádné změny na úrovni buněčností CSF ani změny energetické. V likvorovém kompartmentu pacientů s mírnými serózními záněty CNS neinfekční etiologie byly pouze v některých případech patrny zvýšené buněčnosti CSF a jisté odchylky hodnot Q glu. , koncentrací laktátu v CSF a hod - not KEB od normálu. V likvorovém kompartmentu pacientů se serózními záněty CNS infekční etiologie byly pozorovány projevy nápadně zvýšené intenzity zánětlivého procesu v likvorovém kompartmentu především na úrovni buněčností CSF, koncentrací laktátu v CSF a hodnot KEB. Vysoká intenzita purulentního zánětlivého procesu bakteriální etiologie v CNS se výrazně projevila na úrovni všech sledovaných parametrů. Nejtěsnější vztah jsme v našem souboru pacientů zjistili mezi buněčnostmi CSF a hodnotami KEB ( ρ = -0,770), následoval vztah mezi buněčnostmi CSF a koncentracemi laktátu v CSF ( ρ = 0,734), hodnotami Q glu. ( ρ = -0,676) a koncentracemi glukózy v CSF ( ρ = -0,544). Využitelnost uvedených parametrů k predikci intenzity zánětlivého procesu v CNS jsme ověřili pomocí multinomiální logistické regresní analýzy. Nejvyšší pre - dikční potenciál měly buněčnost CSF se 71,9 % a KEB se 71,6 % správně zařazených pacientů. Následovaly koncentrace laktátu v CSF s 64,7 %, Q glu. s 58,8 % a koncentrace glukózy v CSF s 54,7 % správně klasifikovaných pacientů. Závěr: Získané výsledky podpořily vhodnost využití úrovní buněčností CSF, koncentrací glukózy v CSF, hodnot Q glu. , kon - centrací laktátu v CSF a hodnot KEB k diagnostice postižení a monitorování intenzity zánětů v CNS. Navíc umožnily vytvořit pořadí energetických parametrů v likvorovém kompartmentu pacientů našeho souboru podle úrovně jejich informačního potenciálu. Nejpříznivějších výsledků pro hodnocení intenzity zánětlivého procesu v CNS tak bylo dosaženo v případě hod - not KEB, následovaly je koncentrace laktátu v CSF a hodnoty Q glu. a nejméně příznivých výsledků jsme dosáhli v případě koncentrací glukózy v CSF.
Objective: 1. Evaluate the numbers of cells in the cerebrospinal fluid (CSF), glucose concentrations in the CSF, values of the glucose quotient (Q glu. ), lactate concentrations in the CSF and values of the coefficient of energy balance (KEB) as indicators of intensity of the inflammatory process in the CSF in groups of patients without CNS impairment, with slight serous inflam - mation of non-infectious aetiology in the CNS, with serous inflammation of infectious aetiology in the CNS and of patients with purulent inflammation in the CNS with extracellular bacteria in pathogenesis. 2. Compare the information potential of the used parameters of the glucose energy metabolism in the CSF compartments in our group of the investigated patients, i.e. concentrations of glucose in the CSF, values of the Q glu. , concentrations of lactate in the CSF and values of the KEB. Design: Retrospective study. Material and Methods: We examined 133 CSF specimens in patients without CNS impairment, 227 CSF specimens in pa - tients with slight serous inflammation with intrathecal synthesis of immunoglobulins of non-infectious aetiology in the CNS, 208 CSF specimens in patients with serous inflammation of infectious aetiology in the CNS and 140 CSF specimens in patients with purulent inflammation in the CNS with extracellular bacteria in pathogenesis. The objects of our interest were numbers of cells in the CSF, concentrations of glucose in the CSF, values of the Q glu. , concentrations of lactate in the CSF and values of the KEB. The D’Agostino Omnibus test, the Kruskal-Wallis test with follow-up post hoc analysis using the Dunn’s method, the Spearman correlation coefficient and the multinomial logistic regression analysis were used for statis - tical analysis of the examined parameters. Results: We did not find any changes in the numbers of cells in the CSF and in energy ratios in the CSF compartment of patients without CNS impairment. We found raised numbers of cells in the CSF and slight alterations of the glucose quo - tients, lactate concentrations in the CSF and the values of the KEB only in some patients with slight serous inflammations of non-infectious aetiology in the CNS. We observed manifestations of conspicuously increased intensity of inflammation in the numbers of cells in the CSF, lactate concentrations in the CSF and the values of the KEB in patients with serous inflam - mations of infectious aetiology in the CNS. Very high intensity of purulent inflammation in the CNS of bacterial aetiology was well apparent in all the evaluated parameters. Concerning the relationship, either direct or indirect, between the number of cells in the CSF and the other parameters, we found the highest correlation between the number of cells in the CSF and the values of the KEB ( ρ = -0.770), followed by the lactate concentrations in the CSF ( ρ = 0.734), the Q glu. ( ρ = -0.676) and the glucose concentrations in the CSF ( ρ = -0.544). We verified the applicability of the parameters mentioned above for prediction of the intensity of inflammation in the CNS via multinomial logistic regression analysis. The number of cells and the KEB, with 71.9 % and 71.6 % respectively, has the highest prediction potential of the correctly classified patients. They were followed by the lactate concentration in the CSF with 64.7 %, the Q glu. with 58.8 % and the glucose concentration with 54.7 % of the correctly classified patients. Conclusion: Our study supports the applicability of the numbers of cells in the CSF, the glucose concentrations in the CSF, the values of the Q glu. , the lactate concentrations in the CSF and the values of the KEB for diagnosing CSF impairment and for monitoring the intensity of inflammation in the CNS. Further, the results enabled determination of the information potential of the energy parameters. The values of the KEB were most suitable for evaluation of the intensity of inflammation in the CNS. Less suitable results were achieved in case of the lactate concentrations in the CSF. Even worse results were observed in case of the values of Q glu. and the least suitable results were observed in case of the glucose concentrations in the CSF.
