Using a registration sheet of a prospective registration system for aplastic anemia (AA)/myelodysplastic syndromes (MDS), by the National Research Group on Idiopathic Bone Marrow Failure Syndromes, Japan, we carried out a survey on examinations for diagnosis of bone marrow failure. Bone marrow trephine biopsy was performed in 66 of 105 cases (63%) [Original diagnosis: AA 51 cases (80%), MDS 12 (32%), undiagnosable 3 (75%)]. Bone marrow aspiration was performed in all cases, and aspiration was performed at least twice in 36 cases (34%). The first-line anatomic site for bone marrow aspiration was the posterior iliac crest (62%). Cytogenetic examination was performed in 93%. The concordance rate between the original and the central review diagnosis was 93% among the studied cases: AA, Idiopathic cytopenia of undetermined significance (ICUS) and MDS in total. Flow cytometry analysis to detect paroxysmal nocturnal hemoglobinuria (PNH)-type blood cells was performed in 32%. 相似文献

A 22-year-old man with chronic active Epstein-Barr virus infection underwent allogeneic bone marrow transplantation (allo-BMT) from an HLA two allele-mismatched unrelated donor. Ten months after allo-BMT, he developed protein-losing enteropathy following a respiratory syncytial virus infection. A diagnosis of a recurrent type of acute graft-versus-host disease (GVHD) was made based on the histopathological findings, such as the infiltration of T lymphocytes into the superficial epithelium and crypts, and apoptotic bodies in crypts. Although methylprednisolone (mPSL: 10 mg/kg) administration for two consecutive days improved gastrointestinal symptoms, acute pancreatitis and severe depression developed in association with corticosteroid treatment. Reduction of mPSL and administration of infliximab (5 mg/kg/dose, 3 times) resulted in rapid improvement of depression and pancreatitis without aggravating intestinal GVHD. Recent studies have demonstrated that tumor-necrosis-factor (TNF)-α is associated with not only GVHD but also depression and acute pancreatitis. In the present case, anti-TNF-α treatment enabled us to reduce corticosteroid dose without aggravating GVHD, which suggests that this approach might be effective for the treatment of depression and acute pancreatitis. 相似文献

Hypergammaglobulinemia is often found in patients with autoimmune diseases, such as systemic lupus erythematosus (SLE), and its level may correlate with disease activity. However, it is unclear whether immunoglobulin G (IgG) displays seasonal changes. We analyzed the seasonal change in serum IgG by assessing 450 patients with connective tissue disease. The serum IgG levels in summer were compared with those in winter from 2006 to 2009. Independent samples from 355 patients were analyzed to confirm results in the first set. The differences in the IgG levels between the two seasons were analyzed in each disease and compared with disease activity. 488 patients without connective tissue disease were analyzed as reference instead of healthy people as control. We found that connective tissue disease patients tended to show higher levels of serum IgG in summer than in winter every year from 2006 to 2009, whereas patients without connective tissue disease did not demonstrate such a tendency. We observed this seasonal tendency in each disease. Seasonal changes weakly correlated with those of anti-DNA antibody in SLE patients and those of disease activity score in rheumatoid arthritis (RA) patients. Serum IgG levels of patients with connective tissue diseases display seasonal variations. Biological and clinical significance of these variations should be elucidated. 相似文献

The aim of reconstruction of the webs for syndactyly of the foot is cosmetic improvement, so skin grafting should be avoided. We present our long-term results of 19 feet with simple cutaneous syndactyly in 15 patients who were treated by an open technique. The bottom of the web was covered with a dorsal rectangular flap and the remaining skin defect was left open to epithelialise spontaneously. This took about 4 weeks. After a mean follow-up of 5.7 years (range 3-9), no hypertrophic scar or pigmentation of the skin had developed. Creeping of the web was seen only during the first postoperative year. The final depth of the web satisfied the families of all patients. As the aim of web reconstruction for syndactyly of the foot is purely cosmetic, we conclude that this simple method is reasonable treatment. 相似文献

This article describes the foundation of a psychoanalytic institute in Japan and how its creation was based on the experience of training at the William Alanson White Institute. The process of starting a new institute is compared to the stages of growing plants, including planting seeds, sprouting, pruning, and transplanting. Creating an “ideal” institute requires a belief in education, the ability to find joy in relating to colleagues, and a capacity to deal with the evaluation process and with healthy tensions among subgroups. 相似文献

Antibody‐mediated rejection after ABO‐incompatible pediatric living donor liver transplantation for propionic acidemia: A case report 下载免费PDF全文

We herein present the case of a four‐yr‐old boy with PA who developed AMR after ABO‐incompatible LDLT despite undergoing B cell desensitization using rituximab. Although the CD19+ lymphocyte count decreased to 0.1% nine days after the administration of rituximab, he developed a high fever which was accompanied by arthralgia due to a streptococcal infection 13 days after rituximab prophylaxis. After the clearance of the infection, he underwent ABO‐incompatible LDLT 36 days after the administration of rituximab. The CD19+ lymphocyte count just prior to LDLT was 1.2%. He developed AMR five days after LDLT, and the antidonor‐type IgM and IgG antibody titers increased to 1:1024 and 1:1024, respectively. He was treated by plasma exchange, IVIG, steroid pulse therapy, and rituximab re‐administration; however, his liver dysfunction continued. Despite intensive treatment, he died due to complicated abdominal hernia, acute renal failure, and ARDS. This case suggests that a streptococcal infection may induce the activation of innate immune responses; thus, additional desensitization therapy should be considered prior to ABO‐incompatible LDLT if B cell reactivation is suspected. 相似文献

High mobility group box 1 (HMGB1), a nuclear protein, once released into the extracellular space under pathological conditions, plays a pronociceptive role in redox-dependent distinct active forms, all-thiol HMGB1 (at-HMGB1) and disulfide HMGB1 (ds-HMGB1), that accelerate nociception through the receptor for advanced glycation endproducts (RAGE) and Toll-like receptor 4 (TLR4), respectively. Thrombomodulin (TM), an endothelial membrane protein, and soluble TM, known as TMα, promote thrombin-mediated activation of protein C and also sequester HMGB1, which might facilitate thrombin degradation of HMGB1. The present study aimed at clarifying the role of thrombin in TMα-induced suppression of peripheral HMGB1-dependent allodynia in mice. Thrombin-induced degradation of at-HMGB1 and ds-HMGB1 was accelerated by TMα in vitro. Intraplantar (i.pl.) injection of bovine thymus-derived HMGB1 in an unknown redox state, at-HMGB1, ds-HMGB1 or lipopolysaccharide (LPS), known to cause HMGB1 secretion, produced long-lasting mechanical allodynia in mice, as assessed by von Frey test. TMα, when preadministered i.pl., prevented the allodynia caused by bovine thymus-derived HMGB1, at-HMGB1, ds-HMGB1 or LPS, in a dose-dependent manner. The TMα-induced suppression of the allodynia following i.pl. at-HMGB1, ds-HMGB1 or LPS was abolished by systemic preadministration of argatroban, a thrombin-inhibiting agent, and accelerated by i.pl. co-administered thrombin. Our data clearly indicate that TMα is capable of promoting the thrombin-induced degradation of both at-HMGB1 and ds-HMGB1, and suppresses the allodynia caused by either HMGB1 in a thrombin-dependent manner. Considering the emerging role of HMGB1 in distinct pathological pain models, the present study suggests the therapeutic usefulness of TMα for treatment of intractable and/or persistent pain. 相似文献
