Characteristics of Cytomegalovirus Infection in the Upper Gastrointestinal Tract en-subtitle= kn-subtitle= en-abstract= kn-abstract=We retrospectively analyzed the cases of 14 patients (9 women, 5 men, mean age: 51.6 years) with cytomegalovirus (CMV) involvement in the esophagus, stomach, and/or duodenum diagnosed at a single center, to determine their endoscopic features and clinical backgrounds. Thirteen patients (92.9%) had hematologic disease; the other had rheumatoid arthritis. Of the former, 12 patients underwent allogeneic hematopoietic stem cell transplantation, and 9 of these patients had graft-versus-host disease (GVHD) before undergoing esophagogastroduodenoscopy (EGD). All 14 patients had been taking one or more immunosuppressive agents including cyclosporine (n=10), corticosteroids (n=9), mycophenolic acid (n=6), tacrolimus (n=3), and methotrexate (n=1). Tests for CMV antigenemia were positive in 11 patients (78.6%). EGD examinations revealed esophageal (n=3), gastric (n=9), and duodenal involvement (n=6). Macroscopically, esophageal lesions by CMV infection presented as redness (n=1), erosions (n=1), and ulcers (n=1). Gastric lesions manifested as redness (n=7), erosions (n=3), exfoliated mucosa (n=2), and verrucous erosions (n=1). Mucosal appearances in the duodenum varied: redness (n=2), ulcers (n=2), multiple erosions (n=2), single erosion (n=1), edema (n=1). CMV was detected even in the intact duodenal mucosa (n=1). In conclusion, physicians must recall the relevance of CMV infection when any mucosal alterations exist in the upper gastrointestinal tract of immunosuppressed patients. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Division of Infection Control and Prevention, Osaka University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Departments of Endoscopy, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine kn-affil= en-keyword=cytomegalovirus kn-keyword=cytomegalovirus en-keyword=duodenum kn-keyword=duodenum en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=esophagus kn-keyword=esophagus en-keyword=stomach kn-keyword=stomach END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=4 article-no= start-page=279 end-page=283 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201608 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Case of Diffuse Large B-cell Lymphoma in a Patient with IgG4-Related Autoimmune Pancreatitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here, we discuss the risk of malignancies, particularly malignant lymphoma in patients with IgG4-related disease. The importance of pathological analysis to reach the appropriate diagnosis in such cases should be emphasized. en-copyright= kn-copyright= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OchoKazuki en-aut-sei=Ocho en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraKosuke en-aut-sei=Kimura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=IgG4-related disease kn-keyword=IgG4-related disease en-keyword=autoimmune pancreatitis kn-keyword=autoimmune pancreatitis en-keyword=immunophenotyping kn-keyword=immunophenotyping en-keyword=diffuse large B-cell lymphoma kn-keyword=diffuse large B-cell lymphoma END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=3 article-no= start-page=217 end-page=221 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Increased Serum KL-6 Levels Induced by Pulmonary Mycobacterium Avium Complex Infection in a Patient with RA-associated Lung Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels. Following tapering of prednisolone, chest image findings deteriorated again as levels of KL-6 increased, suggesting recurrence of RA-ILD. Bronchoscopic examination revealed active MAC infection. Treatment of MAC infection not only improved chest image findings but also decreased KL-6 levels in serum, suggesting that KL-6 was increased by active MAC infection by itself, not by recurrence of RA-ILD. To the best of our knowledge, this is the first documentation of KL-6 elevation in serum in association with active MAC infection. en-copyright= kn-copyright= en-aut-name=WasedaKoichi en-aut-sei=Waseda en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OchoKazuki en-aut-sei=Ocho en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KimuraKosuke en-aut-sei=Kimura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Departments of Hematology, Oncology, Allergy and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Departments of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=KL-6 kn-keyword=KL-6 en-keyword=mycobacterium avium complex kn-keyword=mycobacterium avium complex en-keyword=pulmonary nontuberculous mycobacterium infection kn-keyword=pulmonary nontuberculous mycobacterium infection en-keyword=rheumatoid arthritis-associated interstitial lung disease kn-keyword=rheumatoid arthritis-associated interstitial lung disease en-keyword=bronchial alveolar lavage kn-keyword=bronchial alveolar lavage END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=2 article-no= start-page=123 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Complication of Chronic Eosinophilic Pneumonia in an Elderly Patient with Sj?gren Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=An 81-year-old Japanese male with primary Sj?gren syndrome (pSS) developed a low-grade fever and productive cough which were refractory to antibiotic therapy. Based on the high level of eosinophils observed in his bronchial alveolar lavage, he was diagnosed with chronic eosinophilic pneumonia (CEP) and successfully treated by oral prednisolone. Interstitial lung diseases associated with pSS (pSS-ILDs) usually present as nonspecific interstitial pneumonia or usual interstitial pneumonia; therefore, the present case is extremely unique in that the patient?s condition was complicated with CEP. A diagnosis of advanced gallbladder cancer was made in the patient?s clinical course, suggesting the advisability of a whole-body workup in cases of pSS, especially in elderly patients. en-copyright= kn-copyright= en-aut-name=WasedaKoichi en-aut-sei=Waseda en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TerasakaTomohiro en-aut-sei=Terasaka en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraKosuke en-aut-sei=Kimura en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NadaTakahiro en-aut-sei=Nada en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakamuraEri en-aut-sei=Nakamura en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MurakamiKazutoshi en-aut-sei=Murakami en-aut-mei=Kazutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=10 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=11 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=12 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=bronchial alveolar lavage kn-keyword=bronchial alveolar lavage en-keyword=eosinophilic pneumonia kn-keyword=eosinophilic pneumonia en-keyword=eosinophilia kn-keyword=eosinophilia en-keyword=interstitial lung diseases kn-keyword=interstitial lung diseases en-keyword=Sj?gren syndrome kn-keyword=Sj?gren syndrome END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=6 article-no= start-page=379 end-page=383 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=POEMS Syndrome in a 20-year-old Patient Diagnosed Following a Complaint of Reduced Visual Acuity en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of POEMS syndrome in a 20-year-old patient diagnosed after visiting an eye clinic with a chief complaint of reduced visual acuity. A male university student aged 20 years was referred to our department complaining of blurred vision in both eyes that had persisted for 1 month. He also noted headache, nausea, and paresthesia in the lower extremities around the same time. The visual acuity of his right and left eye was 20/40 and 20/20, respectively. Optic disc edema and serous retinal detachment were present. Brain magnetic resonance imaging showed no intracranial abnormalities, while elevated cerebrospinal fluid pressure, reduced nerve conduction velocity in both lower extremities, hepatosplenomegaly, M proteinemia, high blood VEGF levels, osteoblastic and osteolytic changes in the spine, and atypical plasma cells in bone lesions were noted. From the above findings, the patient was diagnosed with POEMS syndrome. He received high-dose dexamethasone, thalidomide, and radiotherapy on the sacral mass, followed by high-dose melphalan with autologous stem-cell support, and showed subsequent systemic and ophthalmologic improvement. Here, we report the youngest case ever of POEMS syndrome with ocular manifestation. If patients have optic disc edema in both eyes with no intracranial space-occupying lesion, POEMS syndrome should be considered in differential diagnosis, regardless of age. en-copyright= kn-copyright= en-aut-name=DoiShinichiro en-aut-sei=Doi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HosogiMika en-aut-sei=Hosogi en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HosokawaMio en-aut-sei=Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawataTetsuhiro en-aut-sei=Kawata en-aut-mei=Tetsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShiragaFumio en-aut-sei=Shiraga en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=POEMS syndrome kn-keyword=POEMS syndrome en-keyword=serous retinal detachment kn-keyword=serous retinal detachment en-keyword=VEGF kn-keyword=VEGF END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=6 article-no= start-page=363 end-page=368 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Severe Case of Peripheral Leukocytosis Initially Diagnosed as Myelodysplastic Syndrome/Myeloproliferative Neoplasm, Unclassifiable, but Possibly Prefibrotic Primary Myelofibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leukocytosis is occasionally seen in patients with presumptive but undiagnosed myeloproliferative disorders (MPD). A 74-year-old woman was admitted to our hospital for tarry stools, anemia, and marked peripheral leukocytosis of 1.4~105/ƒÊL. Gastroenteroscopy revealed an acute gastric and duodenal mucosal lesion that was treated successfully via endoscopic hemoclipping. Bone marrow aspiration revealed marked megakaryocyte proliferation with atypia of naked nuclei and marrow hypercellularity (90% cellularity). A fluorescence in situ hybridization test could not detect the BCR-ABL fusion gene. Bone marrow aspiration later revealed further abnormalities of megakaryocytes. The patient died from cerebral bleeding. The present case fulfilled 2 of the 3 major criteria of primary myelofibrosis according to the World Health Organization 2008 classification:namely, megakaryocytic hyperplasia with hypercellular marrow and granulocytic hyperplasia. However, the megakaryocytic abnormality was not strictly compatible with the criteria. Instead, we considered prefibrotic primary myelofibrosis as a possibility, although myelodysplastic syndrome/myeloproliferative neoplasm, unclassifiable (MDS/MPN-U) was technically the correct diagnosis. The present case shows that MPN diagnosis remains difficult and suggests that other cases of peripheral leukocytosis with diagnosed MDS/MPN-U might include similar findings. en-copyright= kn-copyright= en-aut-name=OtaSeisuke en-aut-sei=Ota en-aut-mei=Seisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramatsuYasushi en-aut-sei=Hiramatsu en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KasaharaAkinori en-aut-sei=Kasahara en-aut-mei=Akinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakadaSaimon en-aut-sei=Takada en-aut-mei=Saimon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UmenaSachio en-aut-sei=Umena en-aut-mei=Sachio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NoguchiToshio en-aut-sei=Noguchi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsumuraTadashi en-aut-sei=Matsumura en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital affil-num=2 en-affil= kn-affil=Department of Hematologic Internal Medicine, Himeji Red Cross Hospital affil-num=3 en-affil= kn-affil=Department of Hematology and Oncology, Okayama University Hospital affil-num=4 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital affil-num=5 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital affil-num=6 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital affil-num=7 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital affil-num=8 en-affil= kn-affil=Department of Hematology and Oncology, Okayama University Hospital affil-num=9 en-affil= kn-affil=Department of Internal Medicine, Himeji St. Mary?s Hospital en-keyword=prefibrotic primary myelofibrosis kn-keyword=prefibrotic primary myelofibrosis en-keyword=leukocytosis kn-keyword=leukocytosis en-keyword=anemia kn-keyword=anemia en-keyword=acute gastric mucosal lesion kn-keyword=acute gastric mucosal lesion en-keyword=multiple cerebral hemorrhages kn-keyword=multiple cerebral hemorrhages END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=2 article-no= start-page=183 end-page=191 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mammalian Target of Rapamycin Inhibitors Permit Regulatory T Cell Reconstitution and Inhibit Experimental Chronic Graft-versus-Host Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic graft-versus-host disease (GVHD) remains a major late complication of allogeneic bone marrow transplantation (BMT). In a previous study, impaired thymic negative selection of the recipients permitted the emergence of pathogenic T cells that cause chronic GVHD using MHC class II-deficient (H2-Ab1 KO) B6 into OH model and CD4(+) T cells isolated from chronic GVHD mice caused chronic GVHD when administered into the secondary recipients. In this study, we evaluated the kinetics of regulatory T cell (Treg) reconstitution in wild type B6 into C3H model. After myeloablative conditioning, host Tregs disappeared rapidly, followed by expansion of Tregs derived from the donor splenic T cell inoculum. However, the donor splenic T cell derived Treg pool contracted gradually and was almost completely replaced by newly generated donor bone marrow (BM)-derived Tregs in the late post-transplantation period. Next, we compared the effects of cyclosporine (CSA) and mammalian target of rapamycin (mTOR) inhibitors on Treg reconstitution. Administration of CSA significantly impaired Treg reconstitution in the spleen and thymus. In contrast, BM-derived Treg reconstitution was not impaired in mTOR inhibitor-treated mice. Histopathological examination indicated that mice treated with GSA, but not mTOR inhibitors, showed pathogenic features of chronic GVHD on day 120. Mice treated with CSA until day 60, but not mTOR inhibitors, developed severe chronic GVHD followed by adoptive transfer of the pathogenic CD4(+) T cells isolated from H2-Ab1 KO into C3H model. These findings indicated that long-term use of CSA impairs reconstitution of BM-derived Tregs and increases the liability to chronic GVHD. The choice of immunosuppression, such as calcineurin inhibitor-free GVHD prophylaxis with mTOR inhibitor, may have important implications for the control of chronic GVHD after BMT. en-copyright= kn-copyright= en-aut-name=SugiyamaHaruko en-aut-sei=Sugiyama en-aut-mei=Haruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasujiYoshiko en-aut-sei=Yamasuji en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinagawaKatsuji en-aut-sei=Shinagawa en-aut-mei=Katsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakeuchiKengo en-aut-sei=Takeuchi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TeshimaTakanori en-aut-sei=Teshima en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=2 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=3 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=4 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=5 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=6 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=7 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=8 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol affil-num=9 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=10 en-affil= kn-affil=Japanese Fdn Canc Res, Inst Canc, Pathol Project Mol Target affil-num=11 en-affil= kn-affil=Hokkaido Univ, Dept Hematol affil-num=12 en-affil= kn-affil=Okayama Univ, Gradu Sch Med Dent & Pharmaceut Sci, Dept Hematol & Oncol en-keyword=Chronic graft-versus-host disease (GVHD) kn-keyword=Chronic graft-versus-host disease (GVHD) en-keyword=Cyclosporine kn-keyword=Cyclosporine en-keyword=Mammalian target of rapamycin (mTOR) inhibitor kn-keyword=Mammalian target of rapamycin (mTOR) inhibitor en-keyword=Regulatory T cell kn-keyword=Regulatory T cell END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20030630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ƒŒƒgƒƒEƒCƒ‹ƒXƒxƒNƒ^[‚É‚æ‚éRŒ´ˆâ“`Žq“±“üCD40-activated B×–E‚ðRŒ´’ñŽ¦×–E‚Æ‚µ‚½RŒ´“ÁˆÙ“I×–EŠQ«T×–EŠ”‚ÌŽ÷—§ kn-title=Efficient Generation of Antigen-Specific Cytotoxic T Cells Using Retrovirally Transduced CD40-Activated B Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KondoEisei en-aut-sei=Kondo en-aut-mei=Eisei kn-aut-name=‹ß“¡‰p¶ kn-aut-sei=‹ß“¡ kn-aut-mei=‰p¶ aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=‰ªŽR‘åŠw END
