目的探讨多发性骨髓瘤患者化疗后感染病原菌及辅助型T淋巴细胞/调节性T淋巴细胞(Th17/Treg)与细胞因子。方法选择核工业四一六医院血液风湿科2016年3月-2019年9月收治的多发性骨髓瘤化疗后感染患者60例作为感染组,选择同期收治的多发性骨髓瘤化疗后未感染患者40例纳入未感染组。对感染组患者感染部位及病原菌进行分析,检测两组患者外周血Th17/Treg、白细胞介素-17(IL-17)、IL-23、干扰素-γ(IFN-γ),对感染组不同分期患者Th17、Treg、Th17/Treg、IL-17、IL-23、IFN-γ水平进行比较。结果多发性骨髓瘤患者化疗后以呼吸道感染为主(71.67%);共培养分离病原菌10株,其中革兰阴性菌4株,革兰阳性菌2株,真菌(白假丝酵母)4株;感染组Th17、Th17/Treg、IL-17、IL-23分别为(2.09±0.61)%、1.77±0.29、(83.81±24.25)pg/ml、(43.51±16.34)pg/ml高于未感染组,Treg、IFN-γ分别为(1.18±0.35)%、(20.81±8.94)pg/ml低于未感染组(P<0.05);三组患者Th17、Treg、Th17/Treg、IL-17、IL-23、IFN-γ总体差异具有统计学意义(P<0.05),其中III期患者Th17、Th17/Treg、IL-17、IL-23分别为(2.41±0.31)%、(2.56±0.23)、(89.86±17.28)pg/ml、(47.61±12.19)pg/ml高于I期及II期患者,Treg、IFN-γ分别为(0.94±0.18)%、(14.29±4.97)pg/ml低于I期及II期患者(P<0.05);II期患者Th17、Th17/Treg、IL-17、IL-23高于I期患者,Treg、IFN-γ则低于I期患者(P<0.05)。结论多发性骨髓瘤患者化疗后以呼吸道感染居多,病原菌总体分布松散,且随临床分期增加Th17/Treg的失衡也逐渐严重,临床应加强病原培养及针对性用药。     

慢性丙型肝炎患者外周血T淋巴细胞亚群变化的临床分析

目的：分析慢性丙型肝炎（CHC）患者外周血T淋巴细胞亚群（CD3+、CD4+和CD8+细胞）以及调节性T淋巴细胞（CD4+CD25+Treg）表达与HCV RNA水平之间的关系。方法选取CHC 患者128例,根据HCV RNA水平高低将他们分为HCV RNA阴性组48例,低病毒组40例（HCV RNA<105 IU/mL）,高病毒组40例（HCV RNA≥105 IU/mL）,另外选取30名健康体检者作为对照组。检测4组样本的外周血T淋巴细胞亚群和调节性T淋巴细胞,分析各组间的差异。结果 CD4+CD25+Treg表达率在HCV RNA高病毒组、低病毒组、阴性组与健康对照组分别为（13.57±1.87）%、（9.38±1.74）%、（5.95±1.28）%和（5.89±1.15）%,差异存在统计学意义（F=35.28, P<0.01）。 CD4+CD25+Treg水平随HCV RNA的升高而升高,两者呈正相关（r=0.625, P<0.05）。 CD3+、CD4+及CD4+/CD8+在4组间的差异均有统计学意义（F=21.51、28.52和15.51,P均<0.01）,其中外周血CD4+百分率及CD4+/CD8+在高病毒组均低于其他3组,在低病毒组均低于健康对照组和阴性组（P均<0.05）。结论 CHC患者外周血CD4+CD25+Treg升高与HCV RNA含量正相关,提示它可能参与了HCV感染慢性化的进程;外周血CD4+百分率及CD4+/CD8+随着HCV RNA水平的升高而明显降低,提示病毒复制水平越高,机体免疫抑制就越明显。     

Efficacy of vaccination against influenza in patients with multiple sclerosis: The role of concomitant therapies

Multiple sclerosis is a chronic progressive demyelinating disease affecting over 2.1 million patients worldwide. Patients affected by MS are exposed to an increased risk of infection from communicable diseases, which may lead to severe disease relapses.     

A comparison of responsiveness indices in multiple sclerosis patients

Responsiveness was measured in a number of health-related quality of life (HRQoL) instruments among which two generic (SF-36 and COOP/WONCA Charts) and one disease-specific instrument, the Disability & Impact Profile (DIP). Subjects were 162 multiple sclerosis patients. The following responsiveness indices were used: effect size, standardised response mean and smallest real difference (SRD). The latter measure gives an indication of the magnitude of real change, i.e. change not attributable to noise or error and can thus be used for the interpretation of change scores in clinical practice whereby change scores larger than the SRD value indicate real change. It is assumed that low SRD values indicate high responsiveness. The results confirmed our expectation that the effect size and standardised response mean are probably less suitable for use in slowly progressive diseases, since they use the average change as the numerator. Therefore, the article focused on the SRD. Compared to scales, items measured on a visual analogue scale show high SRD values. The DIP scales generally show lower SRD values compared to scales of other questionnaires. The SRD seems to be a promising new measure to study responsiveness. More research into the interpretation of this measure is necessary.     

Self-report versus performance measure in gauging level of function with multiple sclerosis

BackgroundMultiple sclerosis (MS) is a debilitating, progressive disease with no known cure. Symptoms vary widely for persons with MS and measuring levels of fine motor, gross motor and cognitive function is a large part of assessing disease progression in both clinical and research settings. While self-report measures of function have advantages in cost and ease of administration, questions remain about the accuracy of such measures and the relationship of self-reports of functioning to performance measures of function.ObjectiveThe purpose of this study was to compare scores on a self-report measure of functional limitations with MS with a performance-based measure at five different time points.MethodsSixty participants in an ongoing longitudinal study completed two measures of function annually over a five-year period – the self-report Incapacity Status Scale and the MS Functional Composite (MSFC), a performance test. Pearson correlations were used to explore the association of self-report and performance scores.ResultsThere were moderate to strong correlations among the ISS total (r = −.53 to −.63, p < .01) and subscale scores of gross (r = .79 to .87; p < .01)) and fine (r = .47 to .69; p < .01) motor function and the corresponding MSFC performance measure. The pattern of change over time in most scores on self-report and performance measures was similar.ConclusionFindings suggest that the self-report measure examined here, which has advantages in terms of feasibility of administration and patient burden, does relate to performance measurement, particularly in the area of gross motor function, but it may not adequately reflect cognitive function.

Abstract：

Objective To analyze the changes in CD8low T lymphocyte subsets in patients with occupational chronic lead poisoning. Methods Flow cytometric analysis was used to count the numbers of CD8+ cells. 23 patients with occupational chronic lead poisoning and 20 controls were examined. Results Compared with control group (8.21%±3.02%), the CD8low T lymphocyte (12.98%±5.62%) were significantly increased in patients with occupational chronic lead poisoning. Conclusion Although the ratio of CD +T lymphocyte is normal, the CD8 level is significantly decreased. The increase of CD8low T lymphocyte may be an important phenomenon of immuno-injury induced by lead. CD8low T lymphocyte could be an new direction for research of lead immuno-toxicity.     

Factors associated with poor sleep quality in patients with multiple sclerosis differ by disease duration

BackgroundSleep disturbance is a common symptom of multiple sclerosis (MS) and knowledge about factors that contribute to poor sleep quality is scarce.ObjectiveThe aim was to explore the differences in the prevalence and determinants of poor sleep quality in a sample of patients with MS with disease duration ≤5 years and >5 years.MethodsWe collected data from 152 consecutive patients with MS; 66 patients (78% women, averaged 37.35 ± 10.1 years) were in the group with disease duration ≤5 years and 86 patients (73.3% women, averaged 42.10 ± 9.4 years) in the group with disease duration >5 years. Patients filled out the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, the Multidimensional Fatigue Inventory, one item of the Incapacity Status Scale regarding bladder problems and one item of the Short Form-36 regarding pain. Multiple linear regression was used to analyze the relationship between the study variables.ResultsThe prevalence of poor sleep is significantly higher in patients with longer disease duration (34.8 vs. 51.2%). Anxiety, reduced motivation and mental fatigue (all p < 0.05) were associated with poor sleep quality in patients with disease duration ≤5 years, whereas pain (p < 0.01), depression and mental fatigue (both p < 0.05) were in patients with disease duration >5 years.ConclusionSleep problems are present in patients with MS with both short and long disease duration, but these problems are associated with different factors. These should be recognized and managed in addition to the treatment of sleep disorders.
