We report a case of a male teenager with severe heart and acute renal failure as the dominant clinical manifestations of renovascular hypertension (RVH) caused by atypical giant cell arteritis (GCA). Unrecognized RVH and treatment of the consequent heart failure by angiotensin-converting enzyme inhibitors (ACEI) probably contributed to progression of renovascular disease to bilateral renal artery occlusion. Recurrent "flash" pulmonary edemas could not be prevented until surgical revascularization of the only functioning right kidney was achieved by an aortorenal bypass. Prompt post-operative normalization of heart function and arterial hypertension occurred despite the histopathological finding of the resected renal artery compatible with GCA and 4-year duration of significant renovascular disease. At the last check-up, the patient was asymptomatic, with normal arterial pressure on the prescribed treatment: carvedilol, hydrochlorothiazide, prednisolone 20 mg daily and aspirin. Subsequent follow-up is necessary to observe the evolution of GCA as an exceptionally rare cause of RVH. 相似文献

ABSTRACTCollaboration between physicians and pharmacists is recognized as an important factor for reducing medication errors and improving patient outcomes. Therefore, two pharmacotherapy workshops were delivered in Croatia - one for pre-registration medical (n=42, 4th-6th year) and pharmacy (n=38, 4th-5th year) students, and the other one for physicians (n=18) and pharmacists (n=23). The purpose of this study was to determine whether participation in common pharmacotherapy workshop could improve attitudes among participants towards interprofessional collaboration between pharmacists and physicians. Attitudes were measured by validated questionnaire “Scale of Attitudes Towards Collaboration Between Pharmacists and Physicians” at the beginning and at the end of the workshops. Three complex clinical scenarios were presented during the workshops. Participants were given general information about cases (all participants) and 2 groups of specific information (only for medical students/physicians and only for pharmacy students/pharmacists). For the first scenario, medical and pharmacy students/professionals were not allowed to exchange their specific information. However, participants collaborated for the 2nd and 3rd scenarios in order to achieve the hypothesized therapeutic goals. Before the workshops, pharmacists and pharmacy students showed more positive attitudes than physicians and medical students. However, the workshop contributed in closing the gap by equating health care professionals’ attitudes. Additionally, students’ attitudes were more positive after the workshop with an increase of 10% for medical and 2.2% for pharmacy students. This study indicates that interprofessional pharmacotherapy workshops could significantly improve attitudes toward collaboration between physicians and pharmacists for both students and practicing professionals. 相似文献

The early diagnosis of human cytomegalovirus (CMV) infection in immunosuppressed patients has been improved by molecular detection of CMV DNA. In this study, corresponding EDTA whole blood and EDTA plasma specimens were obtained from 42 bone marrow transplant recipients. For detection of CMV DNA, two commercially available assays, the CMV HHV6,7,8 R-gene (ARGENE), and the artus CMV LC PCR Kit (QIAGEN), were employed. The linearity of both assays was determined by using a clinical EDTA whole blood sample with high CMV DNA load. With the CMV HHV6,7,8 R-gene test, CMV DNA was detected in 40 EDTA whole blood and in 19 EDTA plasma samples, while the artus CMV LC PCR Kit test detected CMV DNA in 27 EDTA whole blood and in 30 EDTA plasma samples. In conclusion, EDTA whole blood samples were found to be the superior material when using the CMV HHV6,7,8 R-gene test. However, this benefit may not exist when employing alternative assays. 相似文献

Oral fluid has been used widely as sample matrix for the detection and quantitation of viral nucleic acids. However, in the vast majority of previous studies, various methods for collection of oral fluid and molecular assays lacking automation and standardization were used. In this study, a new standardized liquid phase-based saliva collection system was employed followed by a fully automated viral nucleic acid extraction and real-time PCR using commercially available in vitro diagnostics (IVD)/Conformité Européene (CE) labeled molecular assays. When the lower limit of detection of herpes simplex virus (HSV)-1/2 DNA, varicella zoster virus (VZV) DNA, and hepatitis C virus (HCV) RNA in spiked oral fluid was tested, the results were found to be comparable to those with defined sample materials recommended by the assay manufacturers. When clinical specimens were investigated, 21 of 25 (84%) oral fluids obtained from patients with clinically apparent herpetic lesions tested positive for HSV DNA, 7 of 10 (70%) oral fluids obtained from patients with Ramsay Hunt Syndrome tested positive for VZV DNA, and 19 of 40 (48%) oral fluids collected from patients with chronic HCV infection tested positive for HCV RNA. The automated extraction instruments completed all extractions without malfunction and no inhibitions were observed throughout the entire study. Liquid phase-based saliva collection in conjunction with automated and standardized commercially available molecular assays allows reliable quantitation of viral nucleic acids in oral fluid samples and may contribute to improved comparable and interpretable test results. 相似文献

Implications of antibodies to pyruvylated glucose in healthy populations for mycobacterioses and other infectious diseases. 总被引:1,自引:0,他引:1 下载免费PDF全文

Members of the Mycobacterium avium-Mycobacterium intracellulare (MAI) complex are typeable because each serovar is characterized by its own specific antigenic glycolipid. By means of an enzyme-linked immunosorbent assay, we studied serum specimens obtained from 148 healthy college students for antibodies to these glycopeptidolipids. Ninety-two (61.5%) of the serum specimens were positive to the specific glycolipid antigen from MAI serovar 8. In a study of a pediatric population, antibodies appeared to develop during adolescence. Individuals with overt mycobacterial disease had a significantly lower incidence (tuberculosis patients, 34.5%; leprosy patients, 25%). We found a lower incidence of positive results in a survey of 96 Japanese serum specimens (29.1%), but the results from a survey of sera obtained from Bombay, India, indicated a large degree of reactivity (55.5%). Antibodies to other MAI serovars (serovars 2, 4, and 11) were not found, except antibodies to MAI serovar 21 were seen in the same individuals with antibodies to serovar 8. The dominant epitope of the MAI serovar 8-specific glycopeptidolipid is a terminal pyruvylated 3-O-methylglucose residue [4,6-(1'-carboxyethylidene)-3-O-methyl-alpha-D-glucopyranosyl] unit, whereas that of the MAI serovar 21 has the same terminal pyruvylated glucose devoid of the 3-methoxy group. Thus the antibodies appear specific for the pyruvylated glucose. It is unclear whether the high prevalence of antibodies to these epitopes reflects a high incidence of subclinical colonization or infection with certain MAI serovars or whether they are acquired through contact with some other related antigen source. 相似文献

Antibodies against beta2-glycoprotein I are among the most commonly detected subset of antiphospholipid antibodies. The inter-laboratory comparability of results is hardly possible due to methodological differences, lack of international standards and different cut-off values. We evaluated an ELISA for the detection of anti-beta2-glycoprotein I using the analytical goals based on biological variations for similar analytes (immunoglobulins). By our ELISA we fulfilled the optimal (IgA, IgM) or minimal (IgG) analytical goals in long-term imprecision. The determination of cut-off values was based on the frequency distribution of results obtained on 434 healthy Caucasians. To aim at a better inter-laboratory comparability we tested two monoclonal antibodies as possible calibrators: HCAL (IgG) and EY2C9 (IgM). Binding properties determined by dilutional curves showed great similarities with polyclonal sera, used as in-house standards. Cut-off values were expressed by concentrations of IgG and IgM monoclonal antibodies (4.5 and 25.3 microg/l). Our study shows the possibility for a successful application of analytical goals based on biological variation even when data for a particular analyte are not available. The expression of cut-off values, obtained on a large scale Caucasian population, by the concentration of IgG and IgM monoclonal antibodies could make possible a more reliable inter-laboratory comparison of data. 相似文献
