代谢综合征交感神经系统兴奋性增高的机制   总被引:2,自引:0,他引:2  
代谢综合征(metabolic syndrome,MS)是以多种代谢异常集簇出现为特点的一组临床症候群,可显著增加心血管疾病的发病率及死亡率,成为现在研究的热点问题.MS的发病机制目前学说主要集中在遗传因素、胰岛素抵抗、致动脉粥样硬化性血脂异常、腹型肥胖和慢性低度炎症状态等方面,然而上述机制并不是独立起作用的,而是各种因素间相互影响,致使很难阐述MS的病理生理机制.大量临床研究证实,MS大多组分包括高血压、腹型肥胖、高胰岛素血症均与交感神经活性增强密切相关,因此国外学者提出交感神经活性增强可作为上述发病机制的共同发病的基础.本文就MS患者交感神经系统(sympathetic nervous system,SNS)兴奋性增强的机制作一综述,以指导临床治疗.  相似文献

Diagnosis and pathogenesis of CNS lupus   总被引:5,自引:0,他引:5  
Summary The central nervous system (CNS) is clinically involved in approximately 40% of all systemic lupus erythematosis (SLE) patients. Minor psychiatric symptoms and abnormalities on neuropsychological testing are being detected with increasing frequency. This review summarizes current thinking concerning the diagnosis and pathogenesis of CNS lupus. The main symptoms of CNS lupus can be diffuse (generalized seizures, psychosis) or focal (stroke, peripheral neuropathies). Neuropsychiatric symptoms often occur in the first year of SLE, but are rarely the presenting symptoms of the disease. In studies on the pathology of CNS lupus, vasculopathy, infarcts and haemorrhages are often observed, whereas vasculitis is rare. Endocardial lesions and mural thrombi have also been reported in 33–50% of CNS lupus patients. In fliagnostic imaging of the CNS, magnetic resonance imaging (MRI) scans often provide evidence for edema or small infarcts, both in focal and diffuse CNS lupus, whereas computerized tomography (CT) scans only show gross abnormalitites. The first reports on position emission tomography (PET) scans in CNS lupus patients show decreased glucose uptake in the brain. The cerebral blood flow decreases during active diffuse and focal CNS lupus. The blood-brain barrier is somewhat more frequently impaired in diffuse CNS lupus. Intrathecal IgG and IgM production is observed in 25–66% of all CNS lupus patient. Various specificities of autoantibodies have been observed in CNS lupus. Of these, anticardiolipin (ACA) antibodies show a well-documented association with focal involvement of the CNS in SLE. These antibodies could cause thrombosis by interfering with the protein C pathway of fibrinolysis. In addition, they are associated with endocardial and valvular heart disease, which is often observed in SLE and which could cause ombolism. The relation between ACA and diffuse CNS lupus is not yet clear. Low-avidity anti-DNA antibodies are also found in CNS lupus, possibly because of their fross-reaction with cardiolipin. Antineuronal antibodies and lymphocytotoxic antibodies have been associated with diffuse CNS lupus and abnormalities on neuropsychological testing. However, the population of these antibodies is rather heterogeneous and it has not been possible to assess a common target antigen. Therefore, it is still obscure whether there is also a second immune-mediated mechanism responsible for the development of the diffuse form of CNS lupus.  相似文献

Primary angiitis of the central nervous system (PACNS) is an idiopathic vasculitis of the small to medium vessels that often eludes diagnosis because of its variable signs and symptoms. A 36‐year‐old woman presented with a 4‐week history of progressive memory loss. Neurological examination revealed only severe cognitive deficits including anterograde amnesia. Magnetic resonance imaging demonstrated multiple ring‐enhancing lesions involving the left frontal lobe and uncus and bilateral thalami. Stereotactic biopsy showed findings consistent with CNS angiitis. Further workup revealed no evidence of systemic disease. We report the first case of biopsy‐proven PACNS presenting as profound isolated anterograde amnesia.  相似文献

Though the incidence of CNS relapse in acute promyelocytic leukemia (AML-M3 FAB classification) has increased following the advent of all-trans retinoic acid (ATRA), still CNS relapse accounts for only 2–3% of all relapses in AML-M3 trated with standard ATRA plus chemotherapy regimen. We report a case of low risk AML-M3 treated with standard therapy, developing CNS relapse while on maintenance therapy with ATRA + 6-mercaptopurine (6-MP) + methotrexate (MTX).  相似文献

Wegener granulomatosis (WG) is a systemic vasculitis of small and medium vessels. It predominantly affects the upper and/or lower respiratory airway and kidneys. Its pathogenesis is not fully understood. WG relatively frequently affects the nervous system (in 30–50% according to the different studies). Most frequently, it manifests as necrotizing vasculitis that leads to the peripheral neuropathies or to the cranial nerves palsy. Impairment of the central nervous system (CNS) is less frequent and occurs in 2–8% of patients. Three major pathogenetic mechanisms were described: CNS vasculitis, spreading of granulomas from the adjacent anatomical areas (paranasal cavities, orbit etc.), and new formation of granulomas in brain tissue. This case report describes patients in whom WG manifested in the form of localized skin involvement and combined CNS involvement that included pituitary gland. Atypical presentation of WG impedes and slows down the process of diagnosis and emphasizes the need for collaboration between medical specialists.  相似文献

13 patients with adult non-lymphocytic leukemia (ANLL) who developed central nervous system (CNS) involvement during the course of their illness are reported and compared with a control group of 26 ANLL patients without CNS involvement. The incidence of CNS involvement was 13/510 patients (2.5%). Initial symptoms and signs and routine laboratory data were not helpful in predicting which patients would ultimately develop CNS involvement. Almost 1/2 of the patients were in clinical and haematological remission at the time of the diagnosis of CNS involvement. Specific treatment to the CNS including intrathecal cytotoxic drugs and/or radiotherapy failed to increase the survival rate significantly. Whether the establishment of an early diagnosis of CNS involvement and the institution of appropriate treatment may improve the prognosis of this complication is a question which presently remains unanswered.  相似文献

Diagnosis of primary central nervous system lymphoma (PCNSL) is challenging, and although brain biopsy remains the gold standard, cerebrospinal fluid (CSF) constitutes a less invasive source of lymphomatous biomarkers. In a retrospective cohort of 54 PCNSL cases tested at diagnosis or relapse, we evaluated the contribution of immunoglobulin heavy chain (IGH) gene clonality and MYD88 L265P detection on both CSF cell pellets and supernatants, in comparison with cytology, flow cytometry, interleukin (IL)-10 and IL-6 quantification. Clonality assessment included a new assay to detect partial IGH-DJ rearrangements. Clonal IGH rearrangements and/or MYD88 L265P mutation were detected in 27 (50%) cell pellets and 24 (44%) supernatant cell-free (cf) DNA. Combining analyses on both compartments, 36 (66%) cases had at least one detectable molecular marker, present only in cfDNA for 9 (16%) of them. While cytology and flow cytometry were positive in only 7 (13.0%) and 9 (17.3%) cases respectively, high IL-10 levels were observed in 36 (66.7%) cases. Overall, taking into account molecular and cytokine results, 46/54 (85%) cases had at least one lymphomatous biomarker detectable in the CSF. These results show that this combination of biomarkers evaluated on both cell pellet and supernatant CSF fractions improves significantly the biological diagnosis of PCNSL.  相似文献

Overall survival in diffuse large B-cell lymphoma (DLBCL) has significantly improved in the last decade, especially after the incorporation of rituximab. Involvement of the central nervous system (CNS) at presentation or at recurrence is an uncommon event, but carries a dismal prognosis with median survival of less than 6 months. Although prophylactic CNS directed therapy is a widely used approach to prevent this complication, randomized clinical trials have been very limited. CNS prophylaxis has inherent toxicities; therefore, identifying the population of patients who would receive most benefit is of utmost importance. From an extensive review of current literature, we report the incidence of CNS relapse in DLBCL and describe the role of CNS prophylaxis in the post-rituximab compared to the pre-rituximab era. We also review the current modalities of CNS prophylaxis and attempt to identify the high-risk patients who would benefit. Lastly, we present a treatment algorithm that defines the role of CNS prophylaxis in the management of patients with DLBCL.  相似文献

Central nervous system (CNS) relapse following R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone) occurs in 2–5% of patents with diffuse large B-cell lymphoma (DLBCL). Many patients aged ≥70 years are unsuitable for high-dose methotrexate (HDMTX) prophylaxis and therefore often receive stand-alone intrathecal prophylaxis. The CNS international prognostic index (CNS-IPI) is a clinical CNS relapse risk score that has not specifically been validated in elderly patients. The value of CNS prophylaxis in patients aged ≥70 years remains uncertain. Data on 690 consecutively R-CHOP-treated DLBCL patients aged ≥70 years were collected across 8 UK centres (2009–2018). CNS prophylaxis was administered per physician preference. Median age was 77·2 years and median follow-up was 2·8 years. CNS-IPI was 1–3 in 60·1%, 4 in 23·8%, 5 in 13·0% and 6 in 3·3%. Renal and/or adrenal (R/A) involvement occurred in 8·8%. Two-year overall CNS relapse incidence was 2·6% and according to CNS-IPI, 1–3:0·8%, 4:3·6%, 5:3·8% and 6:21·8%. Two-year CNS relapse incidence for R/A was 10·0%. When excluding HDMTX (n = 31) patients, there remained no change in unadjusted/adjusted CNS relapse for intrathecal prophylaxis effect according to CNS-IPI. CNS-IPI is valid in elderly R-CHOP-treated DLBCL patients, with the highest risk in those with CNS-IPI 6 and R/A involvement. We observed no clear benefit for stand-alone intrathecal prophylaxis but observed an independent increased risk of infection-related admission during R-CHOP when intrathecal prophylaxis was administered.  相似文献

The clinical and pathological findings of plasmablastic lymphoma (PBL) have been described in the literature but the etiology is not well established, and treatment options are poorly defined. We reviewed patients with PBL in our institution to characterize the clinicopathologic features in our patient population. In this retrospective analysis from a single academic institution, five patients with PBL were identified and analyzed. Human immunodeficiency virus and human herpesvirus 8 (HHV-8) were identified in 40% (two out of five) and 80% (four out of five) of these patients, respectively. Central nervous system (CNS) involvement was identified in four out of five (80%) patients. Interestingly, three out of five patients had a concurrent or preceding second primary malignancy including small lymphocytic lymphoma, endometrial cancer, and nonsmall cell lung cancer. Most of the patients had advanced disease and a poor performance status at diagnosis. Only two of the patients received systemic chemotherapy with an initial partial response. All five patients died; the median overall survival was 1 month. Our experience in patients with PBL indicates that CNS involvement is more common than reported in the literature. Coexistence of a second primary malignancy may be frequent, and prognosis remains dismal with standard lymphoma therapy. Lastly, the role of HHV-8 in the etiopathogenesis needs further trials.  相似文献
