The results of a study of Inter-Alpha-Trypsin Inhibitor (ITI) polymorphism in 281 blood samples are reported in this paper. These samples were taken from healthy individuals of both sexes, unrelated and resident in the Province of Cadiz. The frequency of ITI*1 was 0.617 and of ITI*2 was 0.383. The probability of exclusion in paternity testing was 0.18.  相似文献

We describe the recipient of a marrow graft from an HLA-serologically identical unrelated donor from whom highly potent host-reactive CTL of donor origin were isolated in association with acute GVHD. Extensive sequence and biochemical analysis of the HLA complex of this donor and recipient revealed several disparities in class I and class II HLA with the potential to be recognized by T cells from the donor or the host. The donor-derived CTL exclusively recognized a class I HLA difference associated with HLA-B44. Nucleotide sequencing of donor and recipient cells revealed that the patient possessed the HLA-B*4402 allele recognized by IEF as B44.2 while the donor possessed HLA-B*4403 (IEF variant B44.1). These alleles differ at one amino acid residue located at position 156 in the alpha 2 domain. The donor-derived CTL were shown to be specific for B44.2 by blocking studies and by the lysis of five different B44.2+ unrelated cell lines, two of which were confirmed by sequencing to be homozygous for B*4402. A host-specific difference involving a HLA-DRB1 allele was not recognized by the CTL, neither did HLA differences unique to the donor HLA-B*4403 and HLA-DQ8 elicit a host response. These data show that certain HLA disparities may be tolerated at the same time that other disparities elicit a potent immunologic response. The chemical nature of the difference, its structural impact, as well as the conditions of transplant appear to influence the type of response which occurs.  相似文献

Between May 1984 and October 1995 we performed 114 autologous stem cell transplants for lymphoma in our centre; 77/114 (68%) were transplanted after primary therapy. The conditioning regimen varied according to diagnosis; 26 patients were conditioned with melphalan and total body irradiation, 66 received melphalan and etoposide and the remainder (50) were conditioned with melphalan alone. The median follow-up is 62 months. Only two new haematological malignancies have occurred, both in patients with Hodgkin's disease. One patient developed Ph+ chronic myeloid leukaemia 18 months post-transplant. In this case, because of the timing of the haematological disorder, we considered the malignancy to be concurrent with or to have preceded the transplant. A second patient developed acute myeloid leukaemia 20 months post-transplant. She had been treated for Hodgkin's disease for 10 years and was transplanted in third complete remission. Cytogenetic analysis in this case showed trisomy 11. We believe this to have been an unequivocal second malignancy. Our finding of a 1.1% incidence of secondary haematological malignancy (95% CI 0.02-4.96) from a census population adds weight to the hypothesis that haematological problems post-transplant reflects prior chemotherapy rather than toxicity from the transplant procedure itself.  相似文献

Idiopathic granulomatous hepatitis is a rare disease of unknown cause that is characterized by recurrent fevers and granuloma in the liver. Attempts to define an exact etiology of the fever of granulomatous hepatitis frequently do not yield a precise diagnosis. Idiopathic granulomatous hepatitis was confirmed after a thorough work up and negative cultures and serologies were obtained, and in the absence of another condition that could lead to granulomas in the liver. We have experienced a 67-year-old female patient who presented with prolonged fever for 2 months and revealed granuloma in liver biopsy. She was treated with glucocorticosteroid and defervescence resulted.  相似文献

The medial preoptic nucleus (MPN) is an essential site for the regulation of male sexual behavior. Previous studies using c-fos as a marker for neural activation have shown that copulation increased c-fos expression in the MPN. Neural activation was also present in brain regions that are connected with the MPN and are involved in male sexual behavior, including the posteromedial bed nucleus of the stria terminalis (BNSTpm), posterodorsal preoptic nucleus (PD), posterodorsal medial amygdala (MEApd), and parvocellular subparafascicular thalamic nucleus (SPFp). The present study investigated whether the copulation-induced, activated neurons in these brain regions are involved in the bidirectional connections with the MPN. Therefore, mating-induced Fos expression was combined with application of anterograde (biotinylated dextran amine) or retrograde (cholera toxin B subunit) tracers in the MPN. The results demonstrated that neurons in the BNSTpm, PD, MEApd, and SPFp that project to the MPN were activated following copulation. However, in males that displayed sexual behavior but did not achieve ejaculation, few double-labeled neurons were evident, although both retrogradely labeled neurons and Fos-immunoreactive cells were present. In addition, retrograde neurons that expressed Fos were located in discrete subdivisions within the brain regions studied, where Fos is induced after ejaculation. Likewise, anterogradely labeled fibers originating from the MPN were not distributed homogeneously but were particularly dense in these discrete subdivisions. These results demonstrate that copulation-induced Fos-positive neurons in specific subdivisions of the BNSTpm, PD, MEApd, and SPFp have bidirectional connections with the MPN. Taken together with previous findings, this supports the existence of a discrete subcircuit within a larger neural network underlying male sexual behavior.  相似文献

The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth.  相似文献

We report a 15-year-old boy with chronic myelogenous leukemia who received unrelated bone marrow transplantation (uBMT) after surgical resection of cerebral arteriovenous malformation (AVM). The incidence of cerebral hemorrhage caused by rupture of cerebral ABM in cases of BMT is uncertain. However, since the risk of rupture of AVM was supposed to increase due to both severe thrombocytopenia after intensive chemotherapy and increased intracranical pressure because of total body irradiation (TBI) as preconditioning therapy for BMT, we have first carried out surgical resection of the cerebral AVM, and subsequently performed uBMT. This resulted in a favorable clinical course without serious complications.  相似文献

Two males of 3 and 3 1/2 years of age with the Wiskott-Aldrich syndrome who underwent bone marrow transplantation from an HLA compatible brother following conditioning treatment with busulphan and cyclophosphamide are described. In both patients the taking of the graft was proven by study of blood subgroups and correction of the immunodeficiency, normalization of platelet number and function and disappearance of cutaneous eczema were seen. At 3 and 1 year respectively of the transplantation the patients showed no evidence of graft versus host disease and no severe infections or hemorrhagic episodes have seen.  相似文献

The prognosis of patients with severe capillary leakage syndrome (CLS) after bone marrow transplantation (BMT) is dismal despite aggressive use of intensive care therapy. Because the activated classical pathway of complement and relatively low levels of C1 esterase inhibitor (C1 INH) activity are known features in these patients, we evaluated the efficacy of a therapy using purified, human C1 INH concentrate. Severe CLS was defined as increase in body weight by more than 3% within 24 h combined with generalized edema, impaired hemodynamic system (tachycardia and/or decreased blood pressure), and non-responsiveness to furosemide. Of 142 patients, 22 developed severe CLS. The first seven patients whom we diagnosed with this complication were assessed as control patients. Fifteen patients with severe CLS were treated with C1 INH concentrate using a cumulative dose of 180 units/kg body wt. (initial dose: 60 units/kg, followed by two doses at 30 units/kg and four doses at 15 units/kg, every 12 h). The survival rate of patients with CLS was 57% at 1 year after BMT in the C1 INH treatment group, compared with 14% in the control group (p = 0.008). Eight of 15 treated patients are alive at a median of 9 months (range: 4-55) after BMT. The plasma levels of the complement activation parameters C4d and C5a were 3 +/- 1.1 mg/dl (mean +/- S.D.) and 0.3 +/- 0.1 microgram/l, respectively, prior to BMT, increasing to 8.2 +/- 2.1 mg/dl and 1.3 +/- 0.4 micrograms/l, respectively, at diagnosis of CLS. After infusion of C1 INH concentrate the plasma levels of C5a and C4d normalized. The activity of C1 INH rose to 139 +/- 10% of normal human plasma NHP pool (mean +/- S.D.) after infusion. The CH50 values were not significantly altered. The fluid status normalized within 11 days in 14 of 15 treated patients. The results of this study suggest that therapy with C1 INH concentrate improves the prognosis of patients with CLS after BMT. This has to be confirmed in a randomized, controlled trial.  相似文献

The pulmonary function of 88 consecutive leukemic patients who had undergone allogeneic bone marrow transplantation (BMT) was studied beforehand, at 3 months, at 6 months, and annually thereafter until 5 years after grafting. The parameters for function which are indicative for obstructive and restrictive lung disease deteriorated in all patient groups during the first 3 to 6 months after BMT but partially recovered within one year. Long-term decline in lung function was similar in all patient groups, and neither the onset nor the magnitude of pulmonary dysfunction was related to the occurrence of pulmonary impairment within 6 months after grafting. Multivariate analysis was then employed to assess predictors for long-term pulmonary disease. Despite the obvious effect of chronic graft versus host disease on the course of lung function, it was in itself not a significant predictor of long-term pulmonary outcome. Rather, the conditioning regimen turned out to be indicative; compared with busulfan, fractionated total body irradiation was demonstrated to be clearly superior with a lower incidence of both restrictive and obstructive long-term lung impairment. Our data indicate a previously unknown long-term side effect of busulfan conditioning.  相似文献

OBJECTIVE: To provide an overview of the role of cytomegalovirus (CMV) in the bone marrow transplant (BMT) population and update the current methods of prevention and treatment of CMV infection and disease, with emphasis on CMV interstitial pneumonia (CMV-IP). DATA SOURCES: The current medical literature, including abstracts presented at recent national and international meetings, is reviewed. References were identified by searching the MEDLINE database from January 1988 through June 1994. The reference lists of the published studies and reviews obtained from the initial literature search were reviewed as well. STUDY SELECTION: Data regarding the epidemiology of CMV, the risk factor associated with CMV infection and disease, as well as data on the prevention and the treatment of CMV infection and disease in the BMT population are cited. Specific attention was focused on randomized, placebo-controlled studies pertaining to the prevention of CMV infection and disease in CMV-immunoglobulin G positive recipients undergoing allogeneic BMT. Information from nonrandomized, placebo-controlled studies was included in the absence of stronger data. DATA EXTRACTION: Information contributing to CMV in the BMT population was reviewed. Data supporting and disputing specific preventive and treatment modalities are presented. DATA SYNTHESIS: The incidence of CMV seropositivity in the general population is high and while BMT becomes a widely accepted treatment modality, CMV reactivation and subsequent disease, especially CMV-IP, becomes a significant prognostic factor of morbidity and mortality. Even though antiviral agents such as ganciclovir and foscarnet can inhibit the viral replication in vivo, they have not been able to treat CMV-IP effectively. It has been suggested that CMV-IP is an immunopathologic process that can cause irreversible damage, hence, the low efficacy of antiviral therapy and the associated high mortality. Immunomodulating agents such as intravenous immune globulin and cytomegalovirus hyperimmune globulin can increase the efficacy of antivirals in the treatment of CMV-IP. This further supports the postulated immunopathologic process of this disease. The lack of understanding of the pathophysiology of the disease compromised the efforts of treatment and led to the development of preventive interventions with antiviral and immunomodulatory regimens that resulted in a significantly lower incidence of infection and disease. As a result of current data, the Eastern Cooperative Oncology Group has published guidelines for the prevention and treatment of CMV infection and disease. CONCLUSIONS: The prognosis of CMV disease in the BMT recipients has improved as a result of a wide variety of modifications in the management of BMT recipients. These include an increased understanding of the risk factors associated with CMV infection, routine screening for CMV replication and excretion, and more effective prophylactic regimens. Still, more than half of the patients who develop pneumonia will die, indicating that more studies are needed to increase the understanding of the pathophysiology and refine the preventive and therapeutic regimens against CMV.  相似文献

A 15-year-old girl developed massive, fatal eosinophilic disease following autologous bone marrow transplantation (BMT) for Hodgkin's disease (HD). Prior to autologous BMT, the erythrocyte sedimentation rate (ESR) was elevated, with active HD, but eosinophilia was absent. Post-autologous BMT, ESR and peripheral eosinophilia were observed to correlate with respiratory symptoms. Initial evaluation revealed no recurrent tumor, infection or other identifiable etiology. A diagnosis of chronic eosinophilic pneumonia was made following lung biopsy. A complete response was initially achieved with steroid therapy; however, when steroid therapy was tapered, the eosinophilia and elevated ESR recurred with worsening respiratory symptoms. Terminally, severe pulmonary disease developed and recurrent HD was found in lung, lymph nodes and bone marrow. During episodes of eosinophilia, the patient's serum stimulated her bone marrow as well as control marrow to produce predominantly eosinophilic colonies. Eosinophilic colony production was not observed with patient's sera obtained prior to or during autologous BMT or with control sera. This patient died of eosinophilic inflammatory disease following autologous BMT. The etiology of this disease was not definitely identified but appeared to be due to an eosinophilic-stimulating factor which developed after autologous BMT.  相似文献

We have intensely followed 45 consecutive women who underwent high-dose chemotherapy (cyclophosphamide/cisplatin/BCNU) and autologous bone marrow transplant (HDC/ABMT) for primary breast cancer with pulmonary function testing and computed tomography at regular intervals up to 126 wk (median follow-up, 72 wk). Our results show a high incidence of interstitial pneumonitis requiring steroids (64%), but no deaths due to pulmonary toxicity. The DL(CO) reaches a nadir of 58.2 +/- SEM 3.4 (expressed as a percent of baseline value) 15-18 wk following HDC/ABMT, and marginally improves with time. To a much lesser extent, vital capacity is reduced with a parallel drop in FEV1, suggesting mild restrictive changes without significant obstruction. Patients who develop pulmonary symptoms of cough or dyspnea have a corresponding significantly greater and earlier decline in DL(CO). Chest computed tomography was neither sensitive nor specific for diagnosing pulmonary toxicity. For patients who received steroids for pulmonary toxicity, there was a subsequent improvement in DL(CO) of 17.1% (p = 0.0001). Because our patients do not fit with the recent definition of idiopathic pulmonary syndrome (IPS), we propose the term delayed pulmonary toxicity syndrome (DPTS) to better describe the milder form of lung toxicity seen in our patient population. We were unable to correlate the severity of DPTS with age, tobacco use, baseline pulmonary function, or systemic exposure to BCNU, cyclophosphamide, or cisplatin. These data suggest that factor(s) other than, or in addition to, chemotherapy systemic exposure can contribute to DPTS. Furthermore, early identification and institution of systemic corticosteroids may improve lung function.  相似文献

PURPOSE: To determine the incidence, natural history, and risk factors associated with myelodysplastic syndrome (MDS) occurring as a late complication following autologous bone marrow transplantation for patients with non-Hodgkin's lymphoma. METHODS: We retrospectively reviewed the charts of all 262 patients who underwent autologous bone marrow transplantation for non-Hodgkin's lymphoma at the Dana-Farber Cancer Institute from 1982 through 1991. Although patients received a variety of treatments before they were eligible for transplant, identical myeloablative therapy (cyclophosphamide 60 mg/kg/d for 2 days plus total-body irradiation twice daily for 3 days) was administered in each case. By collecting data on pretransplant and early posttransplant variables, we attempted to identify risk factors for the development of MDS. RESULTS: The crude overall incidence of posttransplant MDS or acute myeloid leukemia (AML) was 7.6%. The actuarial risk at 6 years was 18% +/- 9%. The median time of onset was 31 months (range, 10 to 101) after transplant or 69 months (range, 27 to 141) after initial treatment for lymphoma. Pretreatment variables predictive for the development of MDS (univariate analysis) included prolonged interval between initial treatment and the transplant procedure (P = .003), increased duration of exposure to chemotherapy (P = .019) or to alkylating agents (P = .045), and use of radiation therapy (P = .032) or pelvic radiation (P = .003) before transplant. CONCLUSION: MDS is a potential complication of autologous bone marrow transplantation for non-Hodgkin's lymphoma; bone marrow stem-cell damage sustained before the transplant may be the most important risk factor.  相似文献

Since information concerning reflux oesophagitis in the elderly is limited, particularly in Japan, the severity and symptomatic profiles of reflux oesophagitis in elderly patients were investigated. One hundred and nineteen patients with reflux oesophagitis found among 2278 endoscopy cases between 1993 and 1996 were investigated in this study. The patients were divided into two groups, elderly and non-elderly. The severity of reflux oesophagitis was estimated by the Los Angeles classification. The presence or absence of typical symptoms (heartburn and regurgitation) was determined by interview. Reflux oesophagitis was not only more frequently found in the elderly group, but was more severe than in the non-elderly. Although the degree of manifestation of typical symptoms was similar between the elderly and the non-elderly with high-grade oesophagitis, the elderly patients with mild reflux oesophagitis were less symptomatic than the non-elderly. Mild reflux oesophagitis in the elderly may be missed due to its rarity of typical reflux symptoms and a substantial number of elderly persons might have subclinical reflux oesophagitis.  相似文献

Mutants of human prothymosin alpha with impaired ability to inhibit yeast Saccharomyces cerevisiae. cerevisiae cell growth were characterized. Two types of prothymosin alpha-inactivating mutations were observed. Mutations that belong to the first type compromised the nuclear entry of prothymosin alpha by affecting its nuclear localization signal. Analysis of subcellular distribution of GFP-prothymosin alpha fusions revealed a bipartite nuclear localization signal that is both necessary and sufficient for nuclear import of the protein in human cells. Mutations of the second type abrogated the inhibitory action of prothymosin alpha through an unknown mechanism, without influencing the nuclear import of the protein.  相似文献

Examination was made of the urinary and biliary excretion of the metabolites of genistein and genistein, the major components of Glycine and Sophora genus in rats. The urine of rats administered genistein orally contained eight metabolites. Three of these metabolites, genistein 4'-O-sulfate (M-1), genistein 7-O-beta-D-glucuronide (M-3), genistein 4'-O-sulfate 7-O-beta-D-glucuronide (M-6), were identified from spectroscopic and chemical data. The bile of rats administered genistein orally contained M-2, M-3 and M-6. M-6, a major biliary metabolite, was isolated and identified from spectroscopic and chemical data. The urine or bile of rats treated with genistein, the glycoside of genistein, contained M-1-M-8 or M-2, M-3, M-6 in the above metabolites. These findings suggest that genistein is absorbed as genistein after hydrolysis in the gastrointestinal tract. The total cumulative amounts of the two metabolites and genistein excreted in the urine during 48h, or of M-6 excreted in the bile during 36h following the oral administration of genistein, were approximately 5.7% or 16.0% of the doses administered, respectively. The result show that M-1, M-3 and M-6, having a free hydroxyl, glucuronide- or sulfate-conjugated hydroxyls at the C-7 or C-4' position, are excreted in the urine and bile as parts of the metabolites of genistein.  相似文献

Hypothalamic-pituitary-adrenal (HPA) axis disturbances in depressed children with a history of abuse were examined. Thirteen depressed abused, 13 depressed nonabused, and 13 normal control children were given 1.0 microgram/kg of human corticotropin-releasing hormone (CRH) intravenously. Blood samples for corticotropin (ACTH) and cortisol were obtained at nine intervals. When compared to depressed nonabused and normal control children, depressed abused children had significantly greater peak, total, and net ACTH secretion post-CRH. Increased ACTH secretion was only observed in depressed abused children experiencing ongoing chronic adversity (marital violence, emotional abuse, poverty, lack of supports). The pattern of findings of the depressed abused children experiencing ongoing adversity parallels the pattern of HPA axis dysregulation reported in animal studies of chronic stress. They add to a growing body of literature suggesting measures of past trauma and current adversity are important sources of variability in psychobiological correlates of major depression.  相似文献

We review the cutaneous manifestations of acute and chronic graft versus host disease (GvHD). Acute GvHD is characterized by initial itching, pain on pressure and erythema which begins on posterior auricular skin, palms and soles. The disease evolves into a typical but nonspecific maculopapular rash. Confluent rashes and follicular erythema may occur. Erosive oral lesions usually develop. The most severe variant of GvHD is toxic epidermal necrolysis, which often has a fatal outcome. The onset of chronic GvHD usually occurs more than 100 days after bone marrow transplantation and may be preceded by the acute form. The spectrum of skin changes includes lichenoid pruritic lesions with violaceous color and scleroderma-like skin involvement. Investigation of unknown rashes in these patients includes skin biopsy, which clearly differentiates leukocytoclastic vasculitis and erythema exsudativum multiforme with lymphocytic vasculitis from cutaneous manifestations of GvHD. Special stains may reveal bacteria and fungus in septicemic patients. The therapeutic options are discussed.  相似文献
