目的探讨布鲁菌病误诊、误治的常见疾病,以增加临床对布鲁菌病的认知度。
方法通过对布鲁菌病误诊个例的文献复习,将误诊疾病按系统进行分类分析。
结果布鲁菌病累及呼吸系统可被误诊为重感冒、支气管炎、支气管肺炎、支原体肺炎、结核性胸膜炎或胸膜间皮瘤,累及循环系统可被误诊为病毒性心肌炎或风湿性心脏病,累及消化系统可被误诊为药物性肝炎、肝硬化或胆道蛔虫病,累及血液系统可被误诊为恶性淋巴瘤,累及神经系统可被误诊为脊髓炎,累及运动系统可被误诊为痛风性关节炎、髋关节滑膜炎、腰椎骨折、腰椎间盘突出或腰椎结核,累及生殖系统可被误诊为睾丸炎、附件炎或先兆早产,其他也可被误诊为成人Still病。
结论布鲁菌病可被误诊为多系统、多器官疾病。详细追问患者的流行病学史、常规进行试管凝集试验(SAT)和虎红平板凝集试验(RBPT)检测是减少布鲁菌病误诊误治的有效途径。 相似文献

结果急性期与亚急性期布鲁菌病患者感染性指标WBC、PCT、hsCRP、ALT、Crea和mALB水平差异均无统计学意义(tWBC = 2.04、P = 0.082,tPCT = 1.98、P = 0.093,thsCRP = 2.18、P = 0.081,tALT = 0.94、P = 0.18,tCrea = 2.31、P = 0.088,tmALB = 2.02、P = 0.085)。急性期布鲁菌病患者AST水平显著低于亚急性期患者(t = 7.59、P = 0.023),且急性期布鲁菌病患者WBC、PCT、hsCRP、ALT、Crea和mALB水平较慢性期患者差异有统计学意义(tWBC = 8.43、P = 0.021,tPCT = 18.36、P = 0.013,thsCRP = 12.35、P = 0.020,tALT = 5.38、P = 0.024,tCrea = 4.81、P = 0.036,tmALB = 10.87、P = 0.020)。亚急性期与慢性期布鲁菌病患者感染性指标WBC、PCT、hsCRP、ALT、Crea和mALB水平差异均无统计学意义(tWBC = 1.12、P = 0.096,tPCT = 2.19、P = 0.082,thsCRP = 2.03、P = 0.084)。随着病期延长,布鲁菌病患者从急性期进展为慢性期,PLT降低、ESR增快、血培养阳性率逐渐降低,但试管凝集试验阳性率一直较高。急性期、亚急性期和慢性期布鲁菌病患者治疗前后PCT和hsCRP差异均有统计学意义(tPCT = 7.85、16.31、27.60,P = 0.018、0.0023、0.003;thsCRP = 9.98、12.14、7.88,P = 0.021、0.036、0.031)。
结论WBC、PLT、ALT、AST、Crea和ESR等指标变化可反映布鲁菌病患者病情的动态变化,血培养和试管凝集试验阳性为布鲁菌病诊断标准;PCT和hsCRP可作为治疗前后患者病情监测及预后的参考依据。 相似文献

Twenty‐one villages in Punjab Province, seven from each region (North, Central & South) were randomly selected to determine the prevalence of B. abortus infection by two age categories (Group A: 0–2 years; Group B: >2 years) in cattle and buffalo populations. In each village, eight blood samples were collected from each age group of cattle and buffaloes. Sera from a total of 672 blood samples (336 each from cattle and buffaloes) were analysed for the presence of antibodies to B. abortus using rose bengal plate agglutination test (RBPT). Further confirmation of the RBPT‐positive samples was carried out using competitive ELISA. Overall, 43 of 672 (6.4%) sera were found positive for the presence of antibodies to B. abortus using RBPT. In cattle, the prevalence of B. abortus antibody was 5.06%, and in buffaloes, it was 7.74%. From the RBPT‐positive sera, 30 (70%) sera were confirmed for B. abortus antibodies using competitive ELISA. Results indicated that the prevalence of infection increased with the age of animals i.e. 3.27% and 9.52% in groups A and B, respectively. In cattle, incidence of these antibodies was 3.57% and 6.54% while in buffaloes, it was 2.98% and 12.50% in groups A and B, respectively. The region‐wise prevalence of B. abortus infection in buffaloes was 3.13%, 4.46% and 4.02% and in cattle, it was 3.13%, 1.79% and 2.68% in Northern, Central and Southern regions, respectively. This study provided baseline data on the occurrence of brucellosis infection in cattle and buffaloes at village level. This is the first study in Punjab province on the prevalence of brucellosis at village level. 相似文献

The relation between presence of antispermatozoal antibodies in infertile men and the inhibition of the in vitro sperm penetration into cervical mucus (CM) was studied with the sperm cervical mucus contact (SCMC) test. The tests were performed with semen from infertile men and from semen donors. The CM used permitted good penetration of normal spermatozoa. The so called "shaking phenomenon", the result of a specific interaction of spermatozoa and CM, was expressed in the shaking percentage (S%).
The S% did not change beyond the experimental error within 30 min after mixing semen and CM. The S% was 30 at the most in 194 out of 198 SCMC tests with normal donor semen and normal pre-ovulatory CM. Significant negative correlations ( P < 0.005) were found between the readings of the sperm penetration meter (SPM) test on one hand and the S%, the sperm agglutination titer in the serum and the sperm agglutination titer in the seminal plasma (SP) on the other hand. Significant positive correlations ( P < 0.005) were found between the S% and the sperm agglutination titer in the SP. The sperm agglutination titer in serum and in SP correlated significantly better ( P < 0.02) with the S% in the SCMC test than with the readings of the SPM test.
It was concluded that: 1. A high S% is highly specific for the presence of antispermatozoal antibodies in infertile men, 2. The SCMC test is more suited than the SPM test for studying the effect of antispermatozoal antibodies on the penetration and migration of spermatozoa into CM, 相似文献

Summary. The most widely used tests to detect seminal and serum sperm antibodies are the mixed antiglobulin reaction (MAR as recommended by WHO) and the tray agglutination test (TAT). It has been suggested that the prognostic significance of sperm antibody tests might be influenced by a concomitant reduction of sperm numbers and/or sperm motility. Furthermore, the relative sensitivity of these sperm antibody tests to detect sperm antibodies is not known. We therefore compared TAT, performed with serum and MAR results retrospectively for 565 infertile patients and MAR IgA and MAR IgG results for 1189 infertile patients. The association of TAT and MAR results with changes in sperm number, morphology and motility was assessed for 565 and 1185 patients, respectively. The influence of MAR and TAT results on sperm cervical mucus penetration test (SCMPT) results was investigated for 349 and 434 patients, respectively. Whereas only 23% of all MAR IgG positive patients were also MAR IgA positive, 82% of all MAR IgA positive patients were also MAR IgG positive. There was a significant ( P < 0.0001) correlation between serum TAT, and MAR results. Positive MAR and TAT results were not associated with reductions in sperm number, motility and morphology. There was a significant correlation between MAR IgG and MAR IgA results and the sperm cervical mucus penetration test (SCMPT) results. According to these results, the MAR IgG would be sufficient as an initial screening for seminal sperm antibodies. MAR IgG negative patients with strong indication for immunologic infertility should also be investigated with the MAR IgA and the serum TAT. Serum and seminal sperm antibodies do not seem to influence male fertility via reductions of sperm number, motility and morphology. However because of their significant influence on SCMPT results, MAR IgG and MAR IgA results seem to be of prognostic significance. 相似文献

The objective of this study was to determine the diagnostic value of maternal serology for the diagnosis of Salmonella Dublin bovine abortion and stillbirth. A retrospective, unmatched, case–control study was carried out using twenty year's data (1989–2009) from bovine foetal submissions to an Irish government veterinary laboratory. Cases (n = 214) were defined as submissions with a S . Dublin culture‐positive foetus from a S . Dublin unvaccinated dam where results of maternal S . Dublin serology were available. Controls (n = 415) were defined as submissions where an alternative diagnosis other than S . Dublin was made in a foetus from an S . Dublin unvaccinated dam where the results of maternal S . Dublin serology were available. A logistic regression model was fitted to the data: the dichotomous dependent variable was the S . Dublin foetal culture result, and the independent variables were the maternal serum agglutination test (SAT ) titre results. Salmonella serology correctly classified 87% of S . Dublin culture‐positive foetuses at a predicted probability threshold of 0.44 (cut‐off at which sensitivity and specificity are at a maximum, J = 0.67). The sensitivity of the SAT at the same threshold was 73.8% (95% CI : 67.4%–79.5%), and the specificity was 93.2% (95% CI : 90.3%–95.4%). The positive and negative predictive values were 84.9% (95% CI : 79.3%–88.6%) and 87.3% (95% CI : 83.5%–91.3%), respectively. This study illustrates that the use of predicted probability values, rather than the traditional arbitrary breakpoints of negative, inconclusive and positive, increases the diagnostic value of the maternal SAT . Veterinary laboratory diagnosticians and veterinary practitioners can recover from the test results, information previously categorized, particularly from those results declared to be inconclusive. 相似文献

A cross‐sectional study was conducted to determine the presence of brucellosis in cattle, goats and humans in farms from south‐western Uganda and identify risk factors associated with brucellosis in these three host groups. Data and serum samples were collected from 768 cattle, 315 goats and 236 humans, with 635 samples of bovine milk, from 70 farms in two different study areas in south‐western Uganda. Sera from livestock were tested with the Rose Bengal Plate test, using B. abortus and B. melitensis antigens, and human sera were tested with a commercial IgG/IgM lateral flow assay. Milk samples were tested using the OIE‐approved milk ring test. Screening tests for brucellosis were positive in 14% of cattle serum, 29% of bovine milk, 17% of goat serum and 11% of human serum samples. There were significant differences in the test prevalence of brucellosis by study site, with levels higher in the study area near Lake Mburo National Park than in the study area near Queen Elizabeth National Park. Multivariable regression models identified risk factors associated with increasing test positivity at the individual and farm levels for cattle, goats and humans. Positive associations were seen between increasing seropositivity of brucellosis in goats, cattle and humans. Results of multivariable analyses suggest that improvements in farm biosecurity and hygiene may reduce the risk of brucellosis on the farm and suggest a role for ticks in bovine brucellosis. Although cattle are the focus of brucellosis control in Uganda, the significant associations between seropositivity in humans and seropositivity in goats suggest that brucellosis in goats may be an important contributor to the epidemiology of the disease on the farm. 相似文献

BACKGROUND: We studied the usefulness of a new assay method that detects only the intact human osteocalcin molecule in haemodialysed patients. METHODS: Iliac bone biopsy specimens obtained from 62 haemodialysed patients were analysed. RESULTS: Bone formation rates (BFR/BS) correlated positively with serum intact osteocalcin concentrations (n=62), osteocalcin concentrations assayed by a conventional method (n=31), parathyroid hormone (PTH) concentrations (n=62), and total alkaline phosphatase concentrations (r=0.602, 0. 588, 0.650, and 0.401 respectively). Based on ROC curve and Youden index analysis, the optimal cut-off value to distinguish adynamic bone disease from a mild lesion was 195 pg/ml of serum PTH concentration (Youden index=0.233) or 30 ng/ml of serum intact osteocalcin concentration (Youden index=0.628). The optimal cut-off value to distinguish between hyperparathyroid bone and a mild lesion was 455 pg/ml of serum PTH level (Youden index=0.63) or 50 ng=ml of serum intact osteocalcin concentration (Youden index=0.634). Since both ROC curve and Youden index suggested that the serum PTH concentration was not a good marker to distinguish adynamic bone from a mild lesion or hyperparathyroid bone, we designed a two-step procedure. The first step was the diagnosis of adynamic bone (cut-off: 65 pg/ml) or hyperparathyroid bone (cut-off: 455 pg/ml) according to serum PTH concentration. In a second step, we assessed serum intact osteocalcin concentration in patients with serum PTH concentrations between 65 and 455 pg/ml. The cut-off values for adynamic and hyperparathyroid bone in this diagnostic approach were 30 and 70 ng/ml respectively. As a result, 49 out of 62 patients were diagnosed properly. The Youden index of this two-step diagnosis was 0.527 and 0.661 for adynamic bone and hyperparathyroid bone respectively. Sensitivity markedly improved to 94.4% and 96.2% for adynamic bone and hyperparathyroid bone respectively, without sacrificing specificity (84.0 and 88.8% respectively). CONCLUSION: Measurement of serum intact osteocalcin concentration is useful for the diagnosis of adynamic bone in haemodialysed patients. A two-step procedure involving also simultaneous measurement of serum PTH concentration further improved the sensitivity of each individual marker while maintaining specificity. 相似文献

Brucellosis is an important animal and human health issue in developing countries. This study aimed to identify risk factors associated with occupational Brucella infection in veterinary personnel in India. Blood samples were collected from 279 veterinary personnel working in the public sector. Sera were tested with rose bengal plate test (RBPT ), standard tube agglutination test (STAT ), and IgG and IgM ELISA s. Information about participant demographics, risk of exposure and infection control practices was collected using a self‐completed questionnaire. The outcome measure of Brucella infection was created based on a positive RBPT or STAT test and a positive IgG ELISA test. Binomial logistic regression analyses were conducted to evaluate associations between explanatory variables and the outcome variable. Of the 279 participants, 61 (21.9%), 67 (24.0%), 55 (19.7%) and 150 (53.8%) were positive in RBPT , STAT , IgM and IgG ELISA , respectively. Compared to a trained veterinarian, veterinary pharmacists and animal handlers had greater odds of being test positive, suggesting that they were at greater risk of Brucella infection. Number of years spent working with animals was associated with greater odds of a person being positive for Brucella infection (p = .015). Counter‐intuitively, those using personal protective equipment (PPE ) for handling sick animals were found to be at greater risk, suggesting that either the use of PPE is inappropriate—making it ineffective—or that it is reverse association whereby those experiencing brucellosis symptoms start using PPE . Brucellosis is a common occupational zoonosis among veterinary personnel in India with the risk being higher in paraveterinary staff than veterinarians and in those who have been practicing for a longer period of time. Further investigations are required to clarify the effectiveness of PPE to reduce Brucella infection in veterinary personnel in India. 相似文献
