Introduction: Preeclampsia has been one of the leading causes of maternal death in Indonesia. It is postulated that its relationship with oxidative stress may be the underlying pathology of the disease. Nutrients and amino acids have been suggested as a scavenger for oxygen-free radicals. No previous study regarding the amino acid status in preeclampsia has been conducted in women in Indonesia. Methods: This was a cross-sectional study of a total of 64 pregnant women, 30 with normal pregnancy and 34 with severe preeclampsia. Data were obtained in Cipto Mangunkusumo National Referral Hospital in Jakarta from July to December 2020. Maternal blood samples were taken during or soon after delivery. Amino acid levels were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Bivariate analysis was then performed. Results: We identified 19 different levels of amino acids in this study. Four amino acids that were elevated in the preeclampsia group were phenylalanine, serine, glycine, and glutamate. Serine (331.55 vs. 287.43; p = 0.03), glycine (183.3 vs. 234.35, p = 0.03), and glutamate levels (102.23 vs. 160.70, p = 0.000) were higher in preeclamptic patients. While in the essential amino acids group, phenylalanine levels (71.5 vs. 85.5, p = 0.023) were higher, and methionine levels (16.3 vs. 12.9, p = 0.022) were lower in preeclamptic patients. Conclusions: These findings suggest that severe preeclampsia had differences in concentration of some amino acids compared to normal pregnancy. Glutamate and methionine were associated with preeclampsia. Furthermore, a more detailed study regarding amino acids in the pathomechanism of preeclampsia is suggested. 相似文献

Common variable immune deficiency (CVID) is an assorted group of primary diseases
that clinically manifest with antibody deficiency, infection susceptibility, and
autoimmunity. Heterozygous mutations in the gene encoding the tumor necrosis factor
receptor superfamily member TACI are associated with CVID and autoimmune
manifestations, whereas two mutated alleles prevent autoimmunity. To assess how the
number of TACI mutations affects B cell activation and
tolerance checkpoints, we analyzed healthy individuals and CVID patients carrying one
or two TACI mutations. We found that TACI interacts with the
cleaved, mature forms of TLR7 and TLR9 and plays an important role during B cell
activation and the central removal of autoreactive B cells in healthy donors and CVID
patients. However, only subjects with a single TACI mutation
displayed a breached immune tolerance and secreted antinuclear antibodies (ANAs).
These antibodies were associated with the presence of circulating B cell lymphoma
6–expressing T follicular helper (Tfh) cells, likely stimulating autoreactive
B cells. Thus, TACI mutations may favor CVID by altering B cell
activation with coincident impairment of central B cell tolerance, whereas residual B
cell responsiveness in patients with one, but not two, TACI
mutations enables autoimmune complications. 相似文献

INTRODUCTION : Antipsychotic medication continues to be an essential component in the treatment of schizophrenia. Neuroleptic malignant syndrome (NMS) is one of the most serious complications of neuroleptic treatment and the optimal therapeutic aftercare regimen for patients is unclear. Also, it is not clear if low-dose neuroleptic maintenance in such patients is safe and efficient enough over time. METHOD : We present a case of a 56-year-old woman suffering from schizoaffective disorder, who was successfully treated with a low dosage of clozapine for 6.5 years following a NMS episode. RESULT : To the best of our knowledge this is the first report of such a long-term beneficial use of low-dose clozapine in a patient who previously underwent such a serious complication. CONCLUSION : Large-scale studies are needed to substantiate this observation. (Int J Psych Clin Pract 2002; 6: 121-123) 相似文献

Post‐transplantation cyclophosphamide versus conventional graft‐versus‐host disease prophylaxis in mismatched unrelated donor haematopoietic cell transplantation 下载免费PDF全文

Post‐transplantation cyclophosphamide (PTCy) is an effective strategy to prevent graft‐versus‐host disease (GVHD) after haploidentical haematopoietic cell transplantation (HCT). We determined the efficacy of PTCy‐based GVHD prophylaxis in human leucocyte antigen (HLA)‐mismatched unrelated donor (MMUD) HCT. We analysed 113 adult patients with high‐risk haematological malignancies who underwent one‐antigen MMUD transplantation between 2009 and 2013. Of these, 41 patients received PTCy, tacrolimus and mycophenolate mofetil (MMF) for GVHD prophylaxis; 72 patients received conventional prophylaxis with anti‐thymocyte globulin, tacrolimus and methotrexate. Graft source was primarily bone marrow (83% PTCy vs. 63% conventional group). Incidence of grade II–IV (37% vs. 36%, P = 0·8) and grade III–IV (17% vs. 12%, P = 0·5) acute GVHD was similar at day 100. However, the incidence of grade II‐IV acute GVHD by day 30 was significantly lower in the PTCy group (0% vs. 15%, P = 0·01). Median time to neutrophil (18 days vs. 12 days, P < 0·001) and platelet (25·5 days vs. 18 days, P = 0·05) engraftment was prolonged in PTCy group. Rates of graft failure, chronic GVHD, 2‐year non‐relapse mortality, relapse, progression‐free survival or overall survival were similar. Our results demonstrate that PTCy, tacrolimus and MMF for GVHD prophylaxis is safe and produced similar results as conventional prophylaxis in patients with one antigen HLA‐MMUD HCT. 相似文献

Live, cold-adapted, temperature-sensitive (ca/ts) Russian influenza A vaccines are prepared in eggs by a 6:2 gene reassortment of the ca/ts donor strain A/Leningrad/134/17/57 (H2N2) (Len/17) with a current wild-type (wt) influenza A strain contributing hemagglutinin (HA) and neuraminidase (NA) genes. However, egg-derived reassortant vaccines are potentially more problematic to manufacture in large quantities than vaccines from cell-based procedures. To compare egg- and cell culture-derived reassortant vaccines, we prepared in Madin Darby canine kidney (MDCK) cells two cloned, ca/ts reassortants (25M/1, 39E/2) derived from Len/17 and a wt reference strain A/New Caledonia/20/99 (H1N1) (NC/wt). Both 25M/1 and 39E/2 reassortants preserved the ca/ts phenotype and mutations described for internal genes of the A/Len/17 parent. When compared to a commercial, egg-derived ca/ts Russian A/17/NC/99/145 (H1N1) New Caledonia vaccine (NC/145), the MDCK-derived reassortant 39E/2 vaccine conferred similar levels of protection in ferrets challenged i.n. with 7 x 10(10) pfu of NC/wt. In a dose-ranging study, the protective vaccine dose for 50% of ferrets (PD50) was less than 1.2 x 10(4) pfu for the 25M/1 vaccine derived by recombination and amplification in MDCK cells. Clonal isolates of ca/ts influenza A/New Caledonia/20/99 (H1N1) obtained by recombination and amplification entirely in MDCK cells can be highly protective i.n. vaccines. 相似文献

Tears in the gluteus medius and minimus tendons, often misdiagnosed as trochanteric bursitis, have recently emerged as an important cause of recalcitrant greater trochanter pain syndrome. Advances in endoscopic surgery of the hip have created opportunities to better evaluate and treat pathology in the peritrochanteric compartment. We reviewed the literature on trochanteric pain syndrome and gluteus medius tendon injuries. Existing techniques for endoscopic and open gluteus tendon repair and potential challenges in restoration of abductor function were analyzed. Partial-thickness undersurface tears of the gluteus medius were identified as a common pathologic entity. Although these tears are otherwise analogous to partial-thickness tears of the rotator cuff, the lack of arthroscopic access to the deep side of the gluteus medius tendon represents a unique technical challenge. To address the difficulty in visualizing and thus repairing undersurface tears of the gluteus medius, a novel endoscopic trans-tendinous repair technique was developed. The purposes of this article are to review the anatomy, pathology, and existing repair techniques of gluteus medius tendon tears and to describe the rationale and surgical steps for endoscopic trans-tendinous repair. 相似文献
