Delirious conditions in surgical ICU - case report.

Delirious conditions are encountered in daily practice in the surgical ward, especially in intensive care units (ICUs). An ordinary surgeon must deal with these conditions very often. The case report of a patient with alcoholic delirium is presented. For a comprehensive view of the issue, we present a simple communication on delirious situations in the ICU. Deliria are classified according to their manifestations, and their etiology is briefly described. For practice, an outline of examinations and treatments is provided which is fundamentally different for alcoholic and nonalcoholic delirium.

Screening of RHD fetal genotype in RhD negative women.

OBJECTIVE: In the Czech Republic in all women within a first trimester screening a laboratory testing for RhD blood group from the peripheral blood should be performed. The aim of the screening is to diagnose RhD negative pregnant women, who may be at risk of developing RhD alloimmunization if the fetus is RhD positive. Currently, the prevention of RhD alloimmunization is carried out regardless of the knowledge of RHD fetal status. Already at the beginning of pregnancy it is possible to determine the RHD genotype of the fetus non-invasively due to cell free fetal DNA circulating in maternal peripheral blood detection. The issue of screening examination of fetal RHD genotype is solved worldwide. In some European countries, the examination is routinely established and thus contributes to the optimization of prenatal care for RhD negative pregnant women, immunoglobulin administration is targeted only in pregnancies with RhD positive fetus. The aim of our study is to evaluate clinical and laboratory effectiveness of fetal RHD genotype screening in RhD negative women by TaqMan Real-time PCR method. Designe: Prospective cohort study. SETTING: Obstetrics and Gynecology Clinic of the Faculty of Medicine University Palacky and the University Hospital Olomouc; Institute of Medical Genetics of the Faculty of Medicine UP and the University Hospital Olomouc; Transfusion Department of the University Hospital Olomouc; Institute of Biophysics of the Faculty of Medicine UP Olomouc. MATERIAL AND METHODS: In 2011-2015 at the University Hospital Olomouc 337 examinations of RHD fetal genotype were performed in pregnant women in first and second trimester and evaluated by TaqMan Real-time PCR, followed by verification of the newborn RHD genotype. RESULTS: Methodology of fetal RHD genotype examination is accurate, reliable and useful in clinical practice. The sensitivity was 97.8%. The specificity was 98.7%. When assessing the effectiveness of the introduction of non- -invasive fetal RHD genotype screening in RhD negative women, it is necessary to assess the medical, organizational and economic aspects. More consistent prevention of RhD alloimmunization in the cases actually indicated may reduce the incidence of RhD alloimmunization. CONCLUSION: From the medical point of view the RHD genotype determination in all RhD negative women at the beginning of pregnancy seems effective. It allows to diagnose about 40% of pregnancies with RhD negative fetuses that do not require administration of IgG anti-D. IgG anti-D should be administered only in indicated cases. Determination of fetal RHD genotype by using TaqMan Real-time PCR is useful in clinical practice.

The effectiveness of KEL and RHCE fetal genotype assessment in alloimmunized women by minisequencing.

OBJECTIVE: To evaluate the effectiveness of the fetal KEL and RHCE genotype assessment in alloimmunized pregnant women by minisequencing. DESIGN: Prospective cohort study. SETTING: Obstetrics and Gynecology Clinic of the Faculty of Medicine UP and the University Hospital Olomouc; Institute of Medical Genetics of the Faculty of Medicine UP and the University Hospital Olomouc; Transfusion Department of the University Hospital Olomouc; Institute of Biophysics of the Faculty of Medicine UP Olomouc. SUBJECT AND METHOD: In the years 2001-2019, 366 samples of pregnant women in the first and second trimester were assessed KEL (n = 327) or RHCE (n = 39) genotype from the free fetal DNA circulating in the peripheral blood by minisequencing. The genotype of the fetus was verified from the buccal smear of the newborn. RESULTS: The KEL genotype was assessed in 327 women (the presence of a variant of the KEL1 alele, which corresponds to the presence of the erythrocyte antigen “K“. The analysis failed in 2 cases (2/327), 16 heterozygote women (KEL1/KEL2) were excluded and in the case of 309 homozygote women (KEL2/KEL2) the fetal KEL genotype was assessed. In the case of 95.8% of the fetuses (296/309) and 95.5% of the newborns (295/309), the KEL2/KEL2 genotype was assessed. In the case of 4.2 % of the fetuses (13/309) and 4.5% of the newborns (14/309), the KEL1/KEL2 genotype was assessed. The sensitivity was 92.86%. The specificity was 100%. The RHCE genotype was assessed in 39 women. In the case of 22 women, the presence of a variant of the RHCE gene, which corresponds to the presence of the erythrocyte antigen “C“/“c“, was assessed. 5 heterozygote women (C/c) were excluded. In the case of 11 homozygote women (C/C), the RHCE genotype was assessed. In the case of 64% (7/11) of the fetuses and newborns, the C/c genotype was assessed, in the case of 36% (4/11) the C/C genotype was assessed. In the case of 6 homozygote women (c/c), the RHCE genotype was assessed. In the case of 67% (4/6) of the fetuses and newborns, the C/c genotype was assessed, in the case of 33% (2/6) the c/c genotype was assessed. The sensitivity and specificity were 100%. In the case of 17 women, the presence of the variant of the RHCE gene, which corresponds to the presence of the erythrocyte antigen “E“/“e“, was assessed. 1 heterozygote woman (E/e) was excluded. In the case of 16 homozygote women (e/e), the RHCE genotype was assessed. In the case of 75% (12/16) of the fetuses and newborns, the e/e genotype was assessed, in the case of 25% (4/16) the E/e genotype was assessed. The sensitivity and specificity were 100%. CONCLUSION: The minisequencing method using the capillary electrophoresis enabled a reliable detection of the fetal KEL and RHCE genotype from the peripheral blood of pregnant women.

Extended follow-up of the CYCLOFA-LUNE trial comparing two sequential induction and maintenance treatment regimens for proliferative lupus nephritis based either on cyclophosphamide or on cyclosporine A.

Objective To evaluate the extended follow-up of the CYCLOFA-LUNE trial, a randomized prospective trial comparing two sequential induction and maintenance treatment regimens for proliferative lupus nephritis based either on cyclophosphamide (CPH) or cyclosporine A (CyA). Patients and methods Data for kidney function and adverse events were collected by a cross-sectional survey for 38 of 40 patients initially randomized in the CYCLOFA-LUNE trial. Results The median follow-up time was 7.7 years (range 5.0-10.3). Rates of renal impairment and end-stage renal disease, adverse events (death, cardiovascular event, tumor, premature menopause) did not differ between the CPH and CyA group, nor did mean serum creatinine, 24 h proteinuria and SLICC damage score at last follow-up. Most patients in both groups were still treated with glucocorticoids, other immunosuppressant agents and blood pressure lowering drugs. Conclusion An immunosuppressive regimen based on CyA achieved similar clinical results to that based on CPH in the very long term.

[RHD genotyping from cell-free fetal DNA circulating in pregnant women peripheral blood and sensitivity assessment of innovated diagnostic approaches for introduction into the clinical practice]. / Stanovení RHD genotypu plodu z plazmy periferní krve tehotné zeny a posouzení citlivosti nových diagnostických postupu pro zavedení do klinické praxe.

OBJECTIVE: Introduction of fetal RHD genotyping from cell-free fetal DNA circulating in the peripheral blood of pregnant women to clinical practice. Sensitivity assessment of innovated method using range of dilution series and internal control of amplification. DESIGN: Procedure creating of noninvasive determination of fetal RHD genotyping from blood plasma of pregnant women. Detection of limit of minority representation RHD+/- sample in the RHD-/- sample. SETTING: University Hospital Olomouc, Institute of Medical Genetics and Fetal Medicine, Clinic of Obstetrics and Gynecology, Transfusion Department. METHODS: TaqMan Real-Time PCR without an internal amplification controls. Optimization and calibration of RHD genotyping using RHD multiplex by TaqMan Real-Time PCR with an internal amplification control and by minisequencing (Snapshot - multiplex) with an internal amplification controls. RESULTS: RHD positive or negative fetuses were determined by amplification curves from Real-Time PCR system that matches the parameters for the evaluation of the output data using series of amplification and contamination parallel controls. TaqMan based Real-Time PCR and minisequencing (SNaPshot) based quantification were able to detect 0.22% of artificial RHD+/- sample diluted in RHD-/- sample. In addition, SNaPshot assay is suitable for heterozygozity and homozygozity recognition. CONCLUSION: Current established and routinely used procedure is based on the detection of exon 7 of the RHD gene and on the series of parallel amplification and contamination controls. Both newly developed methods could be, after validation of the larger set of control samples, introduced into clinical practice.

[Analysis of cell free fetal DNA fragmentation rate in pregnant women during the course of gravidit]. / Analýza fragmentu volné fetální DNA v plazme tehotných zen v prubehu tehotenství.

AIM OF STUDY: To assess cell free fetal DNA (cffDNA) fragmentation rate in pregnant women during the course of gravidity. STUDY DESIGN: QF PCR efficiency in cffDNA and quantitative analyses in particular cffDNA molecular size fractions. SETTING: The study was performed at Department of Medical Genetics and Fetal Medicine, University Hospital Olomouc. METHOD: 1. 363 plasma DNA samples from women in different week of pregnancy (from 4th w.g. to 37th w.g.) were tested for QF PCR efficiency in particular STRs and AMELX/Y. 2. Size fractionated cff DNA (150-300 bp, 300-500 bp, 500-760 bp) was quantified by QF PCR in 91 pregnant women (from 9th w.g. to 40th w.g.). 3. Size fractionated cff DNA from male fetuses was quantified by real time PCR (SRY/internal control) in 22 pregnant women (from 9th w.g. to 36th w.g.). RESULTS: 1. QF PCR efficiency decreased from longer to shorter molecules. 2. The only 500 -760 bp fraction showed cffDNA increase in relation to week of gravidity. 3. Indirect relation between amount of cffDNA and week of gravidity was found in 150-300 bp fraction by Real-time PCR. CONCLUSION: Assembling of all 3 approaches indicates increase of longer cffDNA molecules during the gravidity while level of the short cffDNA molecule fragments probably remains from the approximately 9th w.g. the same.

Cyclosporine A or intravenous cyclophosphamide for lupus nephritis: the Cyclofa-Lune study.

Intravenous cyclophosphamide is considered to be the standard of care for the treatment of proliferative lupus nephritis. However, its use is limited by potentially severe toxic effects. Cyclosporine A has been suggested to be an efficient and safe treatment alternative to cyclophosphamide. Forty patients with clinically active proliferative lupus nephritis were randomly assigned to one of two sequential induction and maintenance treatment regimens based either on cyclophosphamide or Cyclosporine A. The primary outcomes were remission (defined as normal urinary sediment, proteinuria <0.3 g/24 h, and stable s-creatinine) and response to therapy (defined as stable s-creatinine, 50% reduction in proteinuria, and either normalization of urinary sediment or significant improvement in C3) at the end of induction and maintenance phase. Secondary outcomes were incidence of adverse events, and relapse-free survival. At the end of the induction phase, 24% of the 21 patients treated by cyclophosphamide achieved remission, and 52% achieved response, as compared with 26% and 43%, respectively of the 19 patients treated by the Cyclosporine A. At the end of the maintenance phase, 14% of patients in cyclophosphamide group, and 37% in Cyclosporine A group had remission, and 38% and 58% respectively response. Treatment with Cyclosporine A was associated with transient increase in blood pressure and reversible decrease in glomerular filtration rate. There was no significant difference in median relapse-free survival. In conclusion, Cyclosporine A was as effective as cyclophosphamide in the trial of sequential induction and maintenance treatment in patients with proliferative lupus nephritis and preserved renal function.(ClinicalTrials.gov identifier: NCT00976300)

[Biological treatment of rheumatic diseases]. / Biologická terapie revmatických onemocnení.

During recent two decades the progress in the understanding of the pathogenesis of the autoimmune diseases have led to new treatment targets, whose achievement claims new therapeutic advancings. Biological drugs complete or replace conventional immunosuppressive therapies in the treatment of autoimmune diseases. In the treatment of rheumatic diseases are currently used TNFalpha inhibitors and blockade of the IL-1, in phase of clinical trials or actual registration are agents blocking IL-6, the antibodies against B cell and inhibition of activation of T-cells by costimulating blockade with CTLA4Ig. In the Czech Republic are for treating of rheumatic diseases approved TNF blocking drugs. Treatment with this drugs is centred in biological therapy centres and patients are enroled into Registry of patients treated with anti TNFalpha drugs (ATTRA), which enable longterm observation of efficacy and toxicity.

[Treatment of osteoarthritis of the knee joint. Efficacy and tolerance to acemetacin slow release in comparison to celecoxib]. / Behandlung der Gonarthrose. Wirksamkeit und Verträglichkeit von retardiertem Acemetacin im Vergleich zu Celecoxib.

OBJECTIVE: The aim of this trial was to compare acemetacin (ACE) with celecoxib (CEL) in terms of tolerability and efficacy in the treatment of osteoarthritis of the knee joint. METHODS: A total of 105 patients (26-64 years old) suffering from primary osteoarthritis (OA) of the knee were enrolled in this international, multicenter, randomized, double blind controlled trial. Fifty three patients were given ACE and 52 CEL. They were treated with either 90 mg bid of slow release ACE or 200 mg bid of CEL for 6 weeks. Additional gastroprotective therapy was not provided. Tolerability was assessed by physical examination, laboratory tests, vital signs and reports of side effects, as well as by patient and physician global assessments. Efficacy parameters comprised pain assessment by visual analogue scale (VAS) and ordinal scale, WOMAC, SF-36 and patient and physician global impressions of efficacy. In addition, acetaminophen consumption was recorded. RESULTS: In 21 ACE (39.6%) and 19 CEL patients (36.5%), the number of side effects totaled 56 (ACE n=29; CEL n=27) (ns). Mean pain reduction at week 6 was highly significant ( P<0.0001) in both groups and amounted to 38.7 mm (+/-20.3) in the ACE group and to 35.1 mm (+/-18.7) in the CEL group (ns). Very similar results were seen with respect to the other efficacy parameters. CONCLUSION: ACE is not inferior to CEL for the short-term treatment of knee OA in terms of tolerability and efficacy.

[Arthropathy and para-arthropathy in uremic patients on regular hemodialysis]. / Artropatie a paraartropatie u pravidelne hemodialyzovaných uremiku.

Arthropathies and para-arthropathies occur in two thirds of regularly haemodialyzed uraemic subjects. The incidence does not depend on age but the period of haemodialyzation treatment. After five years of treatment the articular apparatus is affected in 100%. In women, as compared with men, the joints of the upper extremities, in particular the small joints of the hands are significantly more frequently affected.
