Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a frequent and severe chronic disease drastically impairing life quality. The underlying pathomechanism is incompletely understood yet but there is convincing evidence that in at least a subset of patients ME/CFS has an autoimmune etiology. In this review, we will discuss current autoimmune aspects for ME/CFS. Immune dysregulation in ME/CFS has been frequently described including changes in cytokine profiles and immunoglobulin levels, T- and B-cell phenotype and a decrease of natural killer cell cytotoxicity. Moreover, autoantibodies against various antigens including neurotransmitter receptors have been recently identified in ME/CFS individuals by several groups. Consistently, clinical trials from Norway have shown that B-cell depletion with rituximab results in clinical benefits in about half of ME/CFS patients. Furthermore, recent studies have provided evidence for severe metabolic disturbances presumably mediated by serum autoantibodies in ME/CFS. Therefore, further efforts are required to delineate the role of autoantibodies in the onset and pathomechanisms of ME/CFS in order to better understand and properly treat this disease. 相似文献

Background/Purpose
Intracranial hemorrhage (ICH) is a severe complication of biliary atresia (BA). We aimed to compare the clinical data of BA patients with and without ICH.Methods
Sixty-three BA patients who underwent Kasai portoenterostomy were included in this study. We retrospectively reviewed their clinical records, and compared the ICH and non-ICH groups.Results
ICH occurred in seven patients (11.1%). The patients with ICH were significantly older at the time of Kasai portoenterostomy (median age: 90.0 vs 65.5?days). The hepatobiliary enzyme levels of the patients with ICH were significantly lower in comparison to the patients without ICH (T-Bil 6.7 vs 9.8?mg/dl; AST 95 vs 194?U/L; ALT 44 vs 114?U/L). On the other hand, the coagulation test values of the patients with ICH were significantly higher in comparison to the patients without ICH (PT 50.0 vs 12.4?s; APTT 200.0 vs 36.9?s). Although the survival rates did not differ to a statistically significant extent, persistent neurological sequelae occurred in two patients in the ICH group.Conclusions
The hepatobiliary enzyme levels of the patients with ICH were significantly lower than those without ICH. However, coagulopathy was found to be significantly more progressive in patients with ICH.Levels of Evidence

Background
Patients with cirrhosis and end-stage liver disease (ESLD) develop severe nutrition deficits that affect morbidity and mortality. Laboratory measures of nutrition fail to fully assess clinical deficits in muscle mass and fat stores. This study employs computed tomography imaging to assess muscle mass and subcutaneous and visceral fat stores in patients with ESLD.Methods
This 1:1 case-control study design compares ESLD patients with healthy controls. Study patients were selected from a database of ESLD patients using a stratified method to assure a representative sample based on age, body mass index (BMI), sex, and model for end-stage liver disease score (MELD). Control patients were trauma patients with a low injury severity score (<10) who had a computed tomography scan during evaluation. Cases and controls were matched for age ± 5 years, sex, and BMI ± 2.Results
There were 90 subjects and 90 controls. ESLD patients had lower albumin levels (P < .001), but similar total protein levels (P = .72). ESLD patients had a deficit in muscle mass (?19%, P < .001) and visceral fat (?13%, P < .001), but similar subcutaneous fat (?1%, P = .35). ESLD patients at highest risk for sarcopenia included those over age 60, BMI<25.0, and female sex. We found degree of sarcopenia to be independent of model for end-stage liver disease score.Conclusions
These results support previous research demonstrating substantial nutrition deficits in ESLD patients that are not adequately measured by laboratory testing. Patients with ESLD have significant deficits of muscle and visceral fat stores, but a similar amount of subcutaneous fat. 相似文献996.
