ABSTRACT

The assumption of accelerated postoperative recovery according to the ERAS (Enhanced Recovery After Surgery) method is good condition of the patient prepared for surgery and gently operated on. Application of ERAS in postoperative care in the situation of patient with multimorbidity requires an individual approach and greater pre-operative preparation. During the healing process, the operation causes a systemic inflammatory reaction in the body, which is proportional to the size of the surgery trauma. There is fluid movement between the intravascular and interstitial spaces, increased protein catabolism, increased susceptibility to infectious complications and increased risk of decompensation of chronic diseases. The mandatory content of the pre-operative examination is a functional cardiopulmonary reserves assessment, nutritional risk screening, update of diagnostic summary and optimization of chronic medication before surgery. Prehabilitation and nutritional preparation before the planned operation is influenced by the time urgency of the operation, but even in the case of cancer, short-term nutritional preparation is indicated., Medical workplaces are the most suitable for parenteral and enteral pre-operative nutrition however some surgical departments perform the preparation themselves if necessary. The GDT (Goal Directed Therapy) regimen with a higher degree of hemodynamic monitoring and intervention is applied in the postoperative care of hemodynamic unstable risk patients. Next to decompensation of a chronic disease is mainly heart rhythm disorders (most often atrial fibrillation), cardiac complications including coronary event, stroke, acute delirium.

ABSTRACT

BACKGROUND AND AIMS: Enhanced recovery after surgery (ERAS) is currently the modern perioperative method of care for improvement of post-surgery patient condition and for minimising various postoperative complications. A question of some negative impact of early postoperative parenteral nutrition on postoperative inflammatory response intensity has not clear-cut answer yet. This pilot project was focused on the possible influence of early parenteral nutrition on the intensity of inflammatory postoperative response to operating trauma in surgical patients. Elected as a model of these conditions were patients with colorectal cancer undergoing major surgery. PATIENTS AND METHODS: 45 patients (of whom 39 were analysed finally) operated for cancer of the large bowel were enrolled into the clinical, prospective, randomized, blinded, and monocentric trial - reference number 201811 S09P of the Ethics committee, University Hospital Hradec Kralove, Czech Republic. Patients were divided into two subgroups according to the type of nutrition: subgroup A - supplemented only with 10% glucose for supported mineral carrier; and subgroup B - supplemented with total parenteral nutrition. Samples of blood and urine were examined immediately after surgery, and on the first, second, and fourth days postoperatively. The inflammatory reaction was monitored by the serum or/and urine concentration of neopterin, tryptophan, and kynurenine, and their urinary ratios with creatinine. The results were analysed by multivariate analysis, and p-values ≤ 0.05 were considered statistically significant. RESULTS: The final total of 39 patients comprised 20 from subgroup A and 19 from subgroup B. The intensity of the inflammatory response detected by the selected inflammatory markers (serum and urine concentrations of neopterin, kynurenine, tryptophan, their serum ratios, and their urinary ratios to creatinine) did not demonstrate statistically significant differences after early administration of the two alternative types of parenteral nutrition. CONCLUSIONS: The results of the study demonstrated the same or a very similar impact on the intensity of postoperative inflammatory response, regardless of whether the patient received intravenous administration of a small simple sugar infusion or total parenteral nutrition during early postoperative care.

ABSTRACT

BACKGROUND: Meropenem dosing for septic critically patients is difficult due to pathophysiological changes associated with sepsis as well as supportive symptomatic therapies. A prospective single-center study assessed whether fluid retention alters meropenem pharmacokinetics and the achievement of the pharmacokinetic/pharmacodynamic (PK/PD) targets for efficacy. METHODS: Twenty-five septic ICU patients (19 m, 6f) aged 32-86 years with the mean APACHE II score of 20.2 (range 11-33), suffering mainly from perioperative intra-abdominal or respiratory infections and septic shock (n = 18), were investigated over three days after the start of extended 3-h i.v. infusions of meropenem q8h. Urinary creatinine clearance (CLcr) and cumulative fluid balance (CFB) were measured daily. Plasma meropenem was measured, and Bayesian estimates of PK parameters were calculated. RESULTS: Eleven patients (9 with peritonitis) were classified as fluid overload (FO) based on a positive day 1 CFB of more than 10% body weight. Compared to NoFO patients (n = 14, 11 with pneumonia), the FO patients had a lower meropenem clearance (CLme 8.5 ± 3.2 vs 11.5 ± 3.5 L/h), higher volume of distribution (V1 14.9 ± 3.5 vs 13.5 ± 4.1 L) and longer half-life (t1/2 1.4 ± 0.63 vs 0.92 ± 0.54 h) (p < 0.05). Over three days, the CFB of the FO patients decreased (11.7 ± 3.3 vs 6.7 ± 4.3 L, p < 0.05) and the PK parameters reached the values comparable with NoFO patients (CLme 12.4 ± 3.8 vs 11.5 ± 2.0 L/h, V1 13.7 ± 2.0 vs 14.0 ± 5.1 L, t1/2 0.81 ± 0.23 vs 0.87 ± 0.40 h). The CLcr and Cockroft-Gault CLcr were stable in time and comparable. The correlation with CLme was weak to moderate (CLcr, day 3 CGCLcr) or absent (day 1 and 2 CGCLcr). Dosing with 2 g meropenem q8h ensured adequate concentrations to treat infections with sensitive pathogens (MIC 2 mg/L). The proportion of pre-dose concentrations exceeding the MIC 8 mg/L and the fraction time with a target-exceeding concentration were higher in the FO group (day 1-3 f Cmin > MIC: 67 vs 27%, p < 0.001; day 1%f T > MIC: 79 ± 17 vs 58 ± 17, p < 0.05). CONCLUSIONS: These findings emphasize the importance of TDM and a cautious approach to augmented maintenance dosing of meropenem to patients with FO infected with less susceptible pathogens, if guided by population covariate relationships between CLme and creatinine clearance.

ABSTRACT

OBJECTIVE: Loss of muscle mass in critically ill patients is associated with serious consequences, such as prolonged mechanical ventilation, intensive care unit confinement, and higher mortality. Thus, monitoring muscle mass, and especially its decline, should provide a useful indicator of morbidity and mortality. Performing evaluations according only to body mass index is imperfect, therefore the aim of this article was to evaluate appropriate methods for muscle mass loss determination in ICU patients. METHODS: For this review, the literature searches were conducted through Embase and Medline, PubMed and Google Scholar databases up to February 2018 for the following Medical Subject Headings terms muscle atrophy, protein catabolism, ICU-aquaired weakness, muscle muss loss, myolysis, critical illness, stress metabolism, computed tomography, magnetic resonance imaging, dual-energy X-ray absorptiometry, neutron activation analysis, anthropometric examination, determination of endogenous metabolites of the skeletal muscles, bioimpedance spectroscopy, ultrasound. RESULT: It appears that ultrasound, which is widely available in hospitals, is the most advantageous method. Muscle ultrasound is non-invasive, relatively inexpensive, and is a bedside method that is free of ionizing radiation. Furthermore, muscle ultrasound also seems to be valid in patients with severe fluid retention, which is a typical complication with other conventional methods. CONCLUSION: Early detection of critical illness neuromyo-pathy could be beneficial for improving the standards of intensive care, and thus reducing the risk of mortality in these patients.

ABSTRACT

PCSK9-inhibitors belong to the new class of hypolipidemic agents. They enhance catabolism of low density lipoprotein cholesterol (LDL-C) through inhibiting activity of proprotein convertase subtilisin/kexin type 9 (PCSK9). They are monoclonal antibodies (alirocumab, evolocumab etc). Under clinical development are also other types of PCSK9-inhibitors which act at a subcellular level. The treatment with PCSK9-inhibitors can be beneficially combined with lipoprotein apheresis (LA). If such treatment using PCSK9-inhibitors is possible with regard to an individual patients genotype, the combination of LA and PCSK9-inhibitors leads to slowing the space of LDL-C increase between individual procedures of apheresis and enables attaining of the lowest possible values of LDL-cholesterolemia for the longest possible period of time. Due to high efficiency of PCSK9-inhibitors lowering LDL-C, but also their lower cost as compared to therapeutic LA, PCSK9-inhibitors now take precedence over the use of extracorporeal lipoprotein apheresis which, nonetheless, still remains the final method for hypolipidemic treatment of patients with severe hypercholesterolemia, who are resistant to conventional therapy while not reaching the target lipid values and at high cardiovascular risk. They belong to extracorporeal elimination methodologies which remove low density lipoprotein (LDL) cholesterol from circulating blood. LA in combination with higher doses of statins and ezetimib currently represents the most efficient method of treatment of homozygous and statin-refractory heterozygous familial hypercholesterolemia (FH). Residual cardiovascular risk in these patients still remains high, in particular because, despite the aforementioned treatment, the target values for lipids according to present recommendations cannot be reached. The combination of LA with the new drugs is promising, primarily due to its potential for further lowering of LDL-cholesterolemia between the individual apheresis procedures. Preliminary results of the ongoing studies indicate that the new hypolipidemic drugs in combination with LA, or when used separately, will substantially enrich and improve the treatment of refractory FH.Key words: alirocumab - atherosclerosis - evolocumab - hypercholesterolemia - cardiovascular disease - lipoprotein apheresis.

ABSTRACT

OBJECTIVE: The association between energy metabolism and prognosis in polytrauma patients has not yet been defined. The aim of this study was to describe energy metabolism and analyze the prognostic value of respiratory quotient (RQ) and nonprotein respiratory quotient (npRQ) in fasting polytrauma patients (fPP) and polytrauma patients with nutritional support (nsPP). METHODS: Twenty-two polytrauma patients (before and after parenteral nutrition administration) and 22 healthy controls (after overnight fasting) were examined on day 4 (median) after admission to the intensive care unit. To evaluate energy expenditure in nsPP and resting energy expenditure in fPP and controls with RQ and npRQ in all groups, we used indirect calorimetry. With regression analysis, the descriptive models of intensive care unit (ICU) length of stay (LOS) and mechanical ventilation time (VT) were derived. RESULTS: RQ and npRQ were significantly lower in fPP than in controls (P < 0.05 and P < 0.01, respectively) and in nsPP (P < 0.05). In nsPP, relationships between RQ or npRQ and the ICU LOS or mechanical VT were demonstrated (P < 0.0001, r = -0.78 for RQ and VT; P < 0.0001, r = -0.78 for npRQ and VT; P < 0.001, r = -0.69 for RQ and LOS; P < 0.001, r = -0.72 for npRQ and LOS). CONCLUSIONS: RQ and npRQ parameters measured by indirect calorimetry in polytrauma patients with parenteral nutrition on the fourth day of ICU stay related to clinical outcomes such as duration of mechanical ventilation and ICU LOS.

ABSTRACT

AIMS: Critically ill patients undergoing aggressive fluid resuscitation and treated empirically with hydrosoluble time-dependent beta-lactam antibiotics are at risk for sub-therapeutic plasma concentrations. The aim of this study was to assess the impact of two covariates - creatinine clearance (Clcr) and cumulative fluid balance (CFB) on pharmacokinetics/pharmacodynamics (PK/PD) target attainment within a week of treatment with meropenem (ME) or piperacillin/tazobactam (PIP/TZB). METHODS: In this prospective observational pharmacokinetic (PK) study, 18 critically ill patients admitted to a surgical Intensive Care Unit (ICU) were enrolled. The primary PK/PD target was free antibiotic concentrations above MIC at 100% of the dosing interval (100%fT>MIC) to obtain maximum bactericidal activity. Drug concentration was measured using liquid chromatography-tandem mass spectrometry. RESULTS: The treatment of both 8 septic patients with IV extended ME dosing 2 g/3 h q8 h and 10 polytraumatized patients with IV intermittent PIP/TZB dosing 4.0/0.5 g q8 h was monitored. 8/18 patients (44%) manifested augmented renal clearence (ARC) where Clcr ≥130 mL/min/1.73 m2. Maximum changes were reported on days 2-3: the median positive CFB followed by the large median volume of distribution: Vdme=70.3 L (41.9-101.5), Vdpip = 46.8 L (39.7-60.0). 100%fTme>MIC was achieved in all patients on ME (aged ≥60 years), and only in two patients (non-ARC, aged ≥65 years) out of 10 on PIP/TZB. A mixed model analysis revealed positive relationship of CFBpip with Vdpip (P=0.021). CONCLUSION: Assuming that the positive correlation between CFB and Vd exists for piperacillin in the setting of the pathological state, then CFB should predict Vdpip across subjects at each and every time point.

ABSTRACT

The guidelines for nutritional support in critically ill adult patients differ in various aspects. The optimal amount of energy and nutritional substrates supplied is important for reducing morbidity and mortality, but unfortunately this is not well known, because the topic is complex and every patient is individual. The aim of this review was to gather recent pertinent information concerning the nutritional support of critically ill patients in the intensive care unit (ICU) with respect to the energy, protein, carbohydrate, and lipid intakes and the effect of their specific utilization on morbidity and mortality. Enteral nutrition (EN) is generally recommended over parenteral nutrition (PN) and is beneficial when administered within 24-48 h after ICU admission. In contrast, early PN does not provide substantial advantages in terms of morbidity and mortality, and the time when it is safe and beneficial remains unclear. The most advantageous recommendation seems to be administration of a hypocaloric (<20 kcal · kg-1 · d-1), high-protein diet (amino acids at doses of ≥2 g · kg-1 · d-1), at least during the first week of critical illness. Another important factor for reducing morbidity is the maintenance of blood glucose concentrations at 120-150 mg/dL, which is accomplished with the use of insulin and lower doses of glucose of 1-2 g · kg-1 · d-1, because this prevents the risk of hypoglycemia and is associated with a better prognosis according to recent studies. A fat emulsion is used as a source of required calories because of insulin resistance in the majority of patients. In addition, lipid oxidation in these patients is ∼25% higher than in healthy subjects.

ABSTRACT

BACKGROUND: In critically ill patients, multi-trauma and intensive therapy can influence the pharmacokinetics (PK) and pharmacodynamics (PD) of antibiotics with time-dependent bacterial killing. Consequently, PK/PD targets (%fT>MIC) - crucial for antimicrobial effects -may not be attained. METHODS: Two patients admitted to the surgical ICU of the University Hospital in Hradec Králove for multiple-trauma were given piperacillin/tazobactam by 1-hour IV infusion 4/0.5 g every 8h. PK variables: total and renal clearance (CLtot, CLR), volume of distribution (Vd), and elimination half-life (T1/2) were calculated, followed by glomerular filtration rate (MDRD) and cumulative fluid balance (CFB-total fluid volume based on 24-h registered fluid intake minus output). The PK/PD target attainment (100%fT>MIC) was defined as free (f) piperacillin plasma concentrations that remain, during the entire dosing interval (T), above the minimum inhibitory concentration (100%fT>MIC) within days 4-8 (when CFB culminates and disappears). Piperacillin concentrations were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and corrected for unbound fraction (22%). RESULTS: CFB culminated over days 2-5 reaching 15-30 L and was associated with a large Vd (29-42 L). While MDRD in patient 1 was low (0.3-0.4 mL s⁻¹ 1.7 m⁻²), that of patient 2 was increasing (> 3.1 mL s⁻¹ 1.7 m⁻²), which was associated with augmented CLR. In patient 2, the fT reached only 62, 52, and 44% on days 4, 6, and 8, respectively. In patient 1, the %fT was much higher, attaining values four to fivefold greater than that targeted. CONCLUSIONS: Critically ill patients are at risk of drug under- or overdosing without dose up-titration with regard to covariate effects and individual drug pharmacokinetics.

ABSTRACT

Lipoprotein apheresis (LA) is an effective treatment method the patients with severe hypercholesterolemia, resistant to the standard therapy. LA is an extracorporeal elimination technique, which specifically removes low density lipoprotein (LDL) cholesterol from the circulation. At present, lipoprotein apheresis, combined with high-dose statin and ezetimibe therapy, is the best available means of treating patients with homozygous and statin refractory heterozygous familial hypercholesterolaemia (FH). However, the extent of cholesterol-lowering achieved is often insufficient to meet the targets set by current guidelines. The recent advent of new classes of lipid-lowering agents provides new hope that the latter objective may now be achievable. These compounds act either by reducing low density lipoprotein (LDL) cholesterol production by inhibiting apolipoprotein B synthesis with an antisense oligonucleotide (mipomersen), or by inhibiting microsomal triglyceride transfer protein (lomitapid), or by enhancing LDL catabolism via monoclonal antibody-mediated inhibition of the activity of proprotein convertase subtilisin/kexin 9 (PCSK9-alirocumab, evolocumab etc). The promising is the combination of LDL-apheresis with new drugs, namely for its potential to further decrease of LDL-cholesterol between apheresis. Depending on the outcome of current trials, it seems likely that these compounds, used alone or combined with lipoprotein apheresis, will markedly improve the management of refractory FH.

ABSTRACT

Colorectal cancer is a clinical condition whose treatment often involves intestinal resection. Such treatment frequently results in two major gastrointestinal complications after surgery: anastomotic leakage and prolonged ileus. Anastomotic leakage is a serious complication which, more often than not, is diagnosed late; to date, C-reactive protein is the only available diagnostic marker. A monocentric, prospective, open case-control study was performed in patients (n = 117) undergoing colorectal surgery. Intestinal fatty acid binding protein (i-FABP), citrulline, D-lactate, exhaled hydrogen, Escherichia coli genomic DNA, and ischemia modified albumin (IMA) were determined preoperatively, postoperatively, and on the following four consecutive days. Bacterial DNA was not detected in any sample, and i-FABP and D-lactate lacked any distinct potential to detect postoperative bowel complications. Exhaled breath hydrogen content showed unacceptably low sensitivity. However, citrulline turned out to be a specific marker for prolonged ileus on postoperative days 3-4. Using a cut-off value of 20 µmol/L, a sensitivity and specificity of ~75% was achieved on postoperative day 4. IMA was found to be an efficient predictor of anastomosis leak by calculating the difference between preoperative and postoperative values. This test had 100% sensitivity and 80% specificity and 100% negative and 20% positive predictive value.

ABSTRACT

PURPOSE: To evaluate the influence of endovascular therapy of ruptured abdominal or iliac aneurysms on total mortality. MATERIALS AND METHODS: We analyzed the mortality of 40 patients from 2005 to 2009, when only surgical treatment was available. These results were compared with the period 2010 to 2013, when endovascular aneurysm repair (EVAR) was assessed as the first option in selected patients. RESULTS: During 2005 to 2009, the mortality was 37.5%. From 2010 to 2013, 45 patients were treated with mortality 28.9%. Open repair was performed in 35 (77.8%) patients and EVAR in 10 (22.2%) patients. The 30-day and 1-year mortality rates of the EVAR group were 0% and 20%, respectively, and the total mortality rate was 30% during follow-up (median 11 months, range 1-42 months). The 30-day mortality in the surgical group remained unchanged, at 37.1%, and 1-year and total mortality rates were 45.7% and 51.4%, respectively. CONCLUSION: Following integration in the treatment algorithm, EVAR decreased total mortality in our center by 8.6%.

ABSTRACT

LDL-apheresis is an extracorporeal elimination technique, which specifically removes LDL-cholesterol from the circulation. There are six methods for the selective LDL-cholesterol removal these days. The main indications for LDL-apheresis are the diagnosis of homozygous familial hypercholesterolemia, heterozygous familial hypercholesterolemia which is refractory the standard care and intolerance of routine care, and also patients with lipoprotein(a) increase resistant to the farmacotherapy. There is still debate which LDL-cholesterolemia is indication for LDL-apheresis therapy, and the recommendation differs among various countries. Despite large randomized trials are missing, there are several good quality studies to conclude, that the beneficial cardiovascular effects of LDL-apheresis in severe hypercholesterolemia are important and beneficial.

ABSTRACT

OBJECTIVE: Hypovolemia has occurs frequently in sepsis. Due to pathologically increased permeability of the capillaries, the fluid leaks to the interstitium. An adequate fluid therapy is the corner stone to achieve circulatory stabilization and sufficient tissue perfusion; on the other hand, according to the data from the literature a tissue swelling is associated with a risk of deteriorated function of the tissues. The study aimed to examine the effect of a positive fluid balance on muscular metabolism. METHODS: The experimental study employed the model of sepsis in the domestical pig. Ten animals were randomly distributed into a control and a septic group. Sepsis was induced by intravenous administration of E. coli, followed by fluid resuscitation by crystaloids. Microdialysis samples were withdrawn at one-hour intervals for a period of 24 hours and values of lactate, pyruvate, glycerol, and glucose. RESULTS: Pearson's method revealed positive correlations between the lactate/pyruvate ratio and cumulative fluid balance in the septic group (R=0.292, p<0.001) and negative correlations in the control group (R=-0.279, p<0.05). In both groups, however, there was a gradual significant decrease in glycerol values. CONCLUSION: Fluid resuscitation results in positive fluid balance in both septic and control animals. This leads to circulatory stabilization of septic animals, but not a decrease in the anaerobic share of glycolysis. A positive fluid balance in control animals does not result in alteration of muscular aerobic glycolysis. Decreasing glycerol levels in both groups give evidence that a positive fluid balance does not exert a negative impact on cell metabolism.

ABSTRACT

Only a few cases of pneumocystis pneumonia (PCP) in Cushing's syndrome have been published in the literature so far. In the majority of these patients, the pneumonia occurred after reduction of the hypercortisolism with medicamentous treatment. We report two cases of PCP during conservative treatment of hypercortisolism. We describe clinical, imaging and laboratory findings in two patients and review published cases of pneumocystits pneumonia in Cushing's syndrome. A 60-year-old woman and 20-year-old man with Cushing's syndrome due to ectopic ACTH syndrome were treated at our department. Both developed pneumocystis pneumonia early after treatment with ketoconazole and ethomidate bromide had been introduced and the levels of cortisol rapidly decreased. PCP prophylaxis in patients with high cortisolemia should be started before treatment of hypercortisolism in current practice. Gradual lowering of plasma cortisol should also reduce the risk of infection by Pneumocystis jiroveci.

ABSTRACT

BACKGROUND AND AIMS: Increasing evidence suggests that preoperative fasting, as was the clinical practice for many decades, might be associated with untoward consequences and that a standardized preoperative intake of nutrients might be advantageous; this is a component of the enhanced recovery after surgery (ERAS) concept. Thus, in a randomized controlled trial we compared preoperative fasting with preoperative preparation with either oral or intravenous intake of carbohydrates, minerals and water. Biochemical, psychosomatic, echocardiographic and muscle-power parameters were assessed in surgical patients with colorectal diseases during the short-term perioperative period. We also assessed the safety of peroral intake shortly before surgery. METHODS: A total of 221 elective colorectal surgery patients in this bicentric, randomized, prospective and blinded clinical trial were divided into three groups: A - patients fasting from midnight (control group); B - patients supported preoperatively by glucose, magnesium and potassium administered intravenously; C - patients supported preoperatively by oral consumption of a specifically composed solution (potion). RESULTS: The general perioperative clinical status of patients in groups C and B was significantly better than those in group A. Psychosomatic conditions postoperatively were found to be best in group C (P < 0.029). The rise in the index of insulin resistance (QUICKI) from the preoperative to the postoperative state was significant in group A (P < 0.05). The systolic and diastolic function of the left ventricle improved postoperatively in group C vs. group A (P < 0.04), and the ejection fraction was also significantly higher postoperatively in group C vs. group A (P < 0.03). The gastric residual volume was 5 ml and the pH of stomach juice was 3.5-5 in all groups without statistically significant difference. No difference was found in the length of hospital stay or the rate of complications. CONCLUSIONS: Preoperative fasting does not confer any benefit or advantage for surgical patients. In contrast, consumption of an appropriate potion composed of water, minerals and carbohydrates offers some protection against surgical trauma in terms of metabolic status, cardiac function and psychosomatic status. Peroral intake shortly before surgery did not increase gastric residual volume and was not associated with any risk.

ABSTRACT

Nonbacterial thrombotic endocarditis (NBTE) is a well-known complication of hypercoagulable states, particularly in patients with malignancies. Its complications comprise thrombembolism rather than valvular dysfunction. We present a case of a 71-year-old man treated for colonic carcinoma, who died 1 month after tumor resection with clinical signs of respiratory failure. Ante mortem, there was no suspicion of cardiac disease. The autopsy revealed NBTE affecting all four cardiac valves simultaneously, as well as multiple systemic and pulmonary thrombemboli. Microscopically, neither microorganisms nor inflammation were found in the thrombi and/or valve tissues. To the best of our knowledge, this is the fourth case of quadri-valvular NBTE reported in the English-written literature so far.
