High-dose (HD) cytosine arabinoside (ARA-C) is more effective treatment than conventional-dose ARA-C regimens for patients with relapsed acute nonlymphocytic leukemia (ANLL). We report here that HD ARA-C given during the first remission of ANLL has resulted in long remission durations and a high proportion of patients who survive more than three years free of disease. From August 1979 to September 1983, 36 adult patients with ANLL in first remission received one to three courses of HD ARA-C (3 g/m2 by one-hour infusion every 12 hours for 12 doses on days 1 through 6) alone or with daunorubicin (30 mg/m2 for two or three doses on days 7 through 9). Three patients died of sepsis or hemorrhage during consolidation, and 14 patients have relapsed from five to 48 months after diagnosis. The remaining 19 patients are in continued complete remission (CCR) from 11 to 62 months. Denoting all deaths in remission as relapse, the actuarial probability of CCR is 42% at 62 months, with an apparent plateau in the survival curve. Of the first 22 patients treated, ten remain in CCR from 37 to 62 months with no therapy for at least three years. Due to its heightened anti-leukemic activity, HD ARA-C allows brief but effective consolidation of ANLL in first remission, with long-term disease-free survival comparable to other approaches. 相似文献

Baka is a platelet alloantigen whose putative allele, Bakb, has not been identified previously. By using a serum, "Har," obtained from a patient with posttransfusion purpura, we describe the platelet alloantigen Bakb. The Har serum reacted with an NP-40-extractable platelet membrane protein of 142 kd with mobility similar to platelet glycoprotein IIb alpha. We found that the antigen recognized by the Har serum is inherited in an autosomal dominant mode with an apparent gene frequency of .39. Chi-square analysis of observed and expected phenotype frequencies indicated that serum Har recognizes Bakb, the anticipated allele of Baka. Our findings provide new evidence for polymorphism of glycoprotein IIb and for the association of posttransfusion purpura with alloimmunization to determinants on this glycoprotein. 相似文献

Lethal midline granuloma (LMG) is associated with Epstein-Barr virus (EBV). The latter has at least two subtypes with different biological properties. The subtypes can be identified by their genomic configuration. Using EBV-RNA (EBER) in situ hybridization and EBV polymerase chain reaction (PCR), we have looked for the presence of EBV in six LMGs and six non-Hodgkin's lymphomas (NHLs) located in the nasopharyngeal region, and determined the subtype of EBV. Six of six LMGs were positive by PCR and EBER in situ hybridization, whereas NHLs were either negative or, in three of six cases, showed few EBER- positive cells considered to be nonneoplastic lymphocytes. The subtype 2 was found in LMG lesions of three of six patients; the remaining three of six patients with LMG had the generally occurring subtype 1. The results indicate that the association of EBV with NHL may depend more on tumor type than on its localization. The occurrence of the rare subtype 2 in LMG may relate to a covert immune defect. 相似文献

Objective To determine the association between endometrial thickness and endometrial histology in a large sample of women using HRT.
Design Results from three multi-centre studies were combined.
Participants Five hundred and sixty-four climacteric women were treated with either sequential, continuous combined or long-cycle therapy.
Main outcome measures The women underwent 717 examinations with both transvaginal ultrasonography and histological examination of the endometrium. Endometrial thickness was measured and associated with the histological findings.
Results Eight cases of endometrial hyperplasia were diagnosed. All the hyperplasias were simple without atypia. Two cases had an endometrial thickness < 4 mm and two a thickness > 8 mm. The > 4 mm threshold for abnormal endometrium had a sensitivity of 75%, a specificity of 47%. a positive predictive value of 2% and a negative predictive value of 99%.
Conclusion No association could be found between the endometrial thickness measured by transvaginal ultrasonography and endometrial pathology. In six out of eight women with simple hyperplasia the endometrium measured > 4 mm. 相似文献

To cite this article: Sandin A, Björkstén B, Böttcher MF, Englund E, Jenmalm MC, Bråbäck L. High salivary secretory IgA antibody levels are associated with less late‐onset wheezing in IgE‐sensitized infants. Pediatr Allergy Immunol 2011; 22 : 477–481. Low levels of secretory IgA (SIgA) and transient IgA deficiency have been associated with an increased risk for allergy, but data are conflicting. The aim was to assess the relationship between salivary SIgA antibody levels at 1 yr and wheezing at age four in a birth cohort, in particular the possible protective role of salivary SIgA in sensitized children. Saliva samples were obtained from all children (n = 67) with a positive skin prick test (SPT) at 1 yr and 212 children with a negative SPT. In all, 200 of these children responded to questionnaires at 4 yrs and 183 were skin prick tested at that age. The levels of salivary SIgA and salivary IgA antibodies to the most common food allergen egg and inhalant allergen cat were analyzed by ELISA. Serum was analyzed for IgE antibodies to egg and cat. Development of late‐onset wheezing was associated with low SIgA levels in children with positive SPT to at least one allergen both at 1 and 4 yrs of age (p = 0.04), as well as in children with circulating IgE antibodies to egg or cat at 1 yr (p = 0.02). None of nine persistently sensitized children with SIgA levels in the upper quartile developed wheezing, when compared to 10/20 children with lower levels (p = 0.01). Older siblings, more than three infections during infancy, at least one smoking parent, and male gender, were all associated with SIgA in the upper quartile. In conclusion, high levels of SIgA antibodies in sensitized infants were associated with significantly less late‐onset wheezing, supporting a protective role against development of asthmatic symptoms. Recurrent infections and other factors supporting an increased microbial pressure during infancy were associated with high levels of salivary SIgA. 相似文献

OBJECTIVE: To investigate patient preference for three established androgen-deprivation therapies for locally advanced prostate cancer; the patient's capacity to decide his therapy; the reasons for selecting a certain mode of therapy; and patient satisfaction with the chosen therapy 3 months after initiation. PATIENTS AND METHODS: In all, 150 patients (mean age 75 years, range 57-89) with previously untreated locally advanced prostate cancer from 13 hospitals were consecutively given the chance to choose between the antiandrogenic oral drug bicalutamide, a gonadotrophin-releasing hormone analogue (GnRH) by injection, or surgical orchidectomy. After discussing the nature of their disease the patients took home written information about prostate cancer and the three different treatment options. After 1 week they were assessed using a questionnaire for biographical data, their attitude towards the different treatment alternatives and their choice of therapy. Three months later the patients completed a questionnaire about the treatment they had undergone. RESULTS: Sixty-three patients (42%) chose bicalutamide, 51 (34%) the GnRH analogue and 36 (24%) orchidectomy; 87% of those choosing bicalutamide, 84% GnRH and 94% orchidectomy, respectively, were sure about their choice but 12%, 17% and 3% of the patients, respectively, had some difficulty in deciding. The most important reasons for the therapy chosen were avoidance of injections and surgery, and a lower risk of impotence (bicalutamide), negative attitude to surgery and tablets (GnRH), and avoidance of injections and tablets (orchidectomy). Almost all patients (98%, 98% and 97%, respectively) were satisfied with their choice after 3 months of treatment. CONCLUSION: There are three equally effective forms of androgen deprivation for locally advanced prostate cancer without known metastases. There are major differences among these treatments in the mode of application and the likelihood and impact of side-effects. When patients are fully informed and play an active role in the treatment decision they are satisfied with their decision 3 months later. 相似文献

The clinical history and histological features of seven cases of granulomatous mastitis are presented. The lesion occurs in young parous women as a tender extra-areolar breast lump. Histologically, non-caseating discrete granulomas are present, confined to breast lobules with, in three cases, coalescence of the granulomas and microabscess formation. Pathogenesis of the changes is discussed. It is thought that granulomatous mastitis is an entity morphologically distinct from duct ectasia/plasma cell mastitis and the commoner forms of granulomatous breast diseases. 相似文献
