Contaminating white blood cells in stored platelet concentrate (PC) are the source of many pro-inflammatory cytokines. These are implicated in transfusion reactions. To study the release of interleukin (IL)-8 and tumor necrosis factor alpha (TNF-α) at different time interval in PC prepared by-platelet rich plasma (PRP) and buffy coat (BC) using different principles. Fifteen PCs were prepared by both the methods. The supernatants of PCs prepared by PRP and BC methods were collected aseptically after 1, 18, 65 and 112 h of preparation. pH, platelet and WBC counts were done. The supernatants were frozen in aliquots at −56 °C for measurement of IL-8 and TNF-α concentration using ELISA. The Mean ± SD value of WBC in PRP-PC was 7.4 ± 3.75 × 107 and in BC-PC 3.9 ± 2.2 × 107. The mean platelet counts were 6.05 ± 1.94 × 1010 and 6.54 ± 2.18 × 1010 respectively. The highest level of IL-8 in one hour was up to 30 pg/ml in both the type of PC. It increased up to 986 pg/ml in PRP-PC and 481 pg/ml in BC-PC at 112 h. IL-8 increased significantly during storage period of 5 days in both types of PCs (P0.000 and P0.01). TNF-α level remained low up to 18 h. The highest level was 72 pg/ml in PRP-PC and 57 pg/ml in BC-PC at 65 h. IL-8 levels significantly increased after one hour of storage and TNF-α. levels were low up to 18 h and then showed increase. The BC-PC had significantly low levels of IL-8 compared to PRP-PC (P0.0001). 相似文献

Highly active antiretroviral therapy has greatly reduced mortality among human immunodeficiency virus (HIV)-infected patients by delaying, and possibly preventing, progression to AIDS. The risk of cardiovascular disease (CVD) is now an important consideration in these patients and may increase as they live longer. Risk factors for CVD, the inflammatory effects of HIV, and the metabolic complications of antiretroviral therapy may accelerate the onset of CVD. Death from myocardial infarction, however, is still rare compared with death from progression of HIV disease, and the benefits of antiretroviral therapy clearly outweigh any associated risk of CVD. In this review, the authors describe the risk of accelerated CVD in HIV-infected individuals, the proposed viral and therapy-related mechanisms of CVD, the clinical features of CVD in these patients, and monitoring and management guidelines to reduce CVD risk. Identifying, monitoring, and treating CVD risk factors in HIV-positive patients is vital to improving their lives and should become standard practice. 相似文献

A 20‐year‐old male presented 3.5 years after intestinal transplantation with rapidly progressive sensorineural hearing loss. Initial brain imaging was consistent with inflammation and/or demyelination. Lumbar puncture was initially non‐diagnostic and a broad infectious workup was unrevealing. Three months after presentation, a repeat LP detected JC virus for which tests had not earlier been conducted. He continued to deteriorate despite withdrawal of prior immunosuppression and addition of mirtazapine, maraviroc, and steroids. He died of progressive neurologic decompensation 5 months after his initial presentation. This case highlights progressive multifocal leukoencephalopathy (PML) as a rare complication after solid organ transplantation and acute sensorineural hearing loss as an unusual first presenting symptom of PML. JC virus should be considered in the differential diagnosis of acute sensorineural hearing loss in any immunocompromised patient. 相似文献

The field of women's health developed based on the recognition that there are important sex‐based differences regarding several aspects of medical illnesses. We performed a literature review to obtain information about differences between women and men for neurological movement disorders. We identified important differences in prevalence, genetics, clinical expression, course, and treatment responses. In addition, we found that female life events, including menstruation, pregnancy, breast feeding, menopause, and medications prescribed to women (such as oral contraceptives and hormone‐replacement therapy), have significant implications for women with movement disorders. Understanding this biological sex‐specific information can help improve the quality and individualization of care for women with movement disorders and may provide insights into neurobiological mechanisms. © 2013 International Parkinson and Movement Disorder Society 相似文献
