We report a case of ANKL in which EBV-specific cytotoxic T lymphocytes (CTLs) were induced. A 41-year-old male suffered from fever, pancytopenia, and hepatosplenomegaly. The number of abnormal large granular lymphocytes in the bone marrow was increased and the cells were positive for CD56 and EBV-encoded small nuclear RNAs. The patient was diagnosed with ANKL and achieved a complete response following intensive chemotherapy. He then underwent allogeneic peripheral blood stem cell transplantation from his sister. Conditioning therapy consisted of total body irradiation and cyclophosphamide. Graft-versus-host disease prophylaxis consisted of cyclosporine and methotrexate. On day 31, complete donor chimerism was achieved and no acute graft-versus-host disease developed. The ANKL relapsed on day 80, and cyclosporine was rapidly tapered and chemotherapy was started. During hematopoietic recovery, the number of atypical lymphocytes increased, but they were donor-derived EBV-specific CTLs. The patient achieved a partial response and EBV viral load decreased to normal range. Unfortunately, ANKL worsen again when the CTLs disappeared from his blood. This is the first case report of ANKL in which induced EBV-specific CTLs may have contributed to disease control..

In this report, we present a rare manifestation of methotrexate (MTX)-associated lymphoproliferative disorders (LPDs) with AITL-like features accompanied by γ-HCD in a 75-year-old man with rheumatoid arthritis (RA). A biopsy specimen was evaluated using immunohistochemistry, clonal analyses of immunoglobulin VH and T-cell receptor γ gene rearrangements by polymerase chain reaction, and Sanger sequencing for confirmation of the structure of deleted γ-HCD clones. The histological features characterized by proliferation of CD4- and PD-1-positive medium-sized T cells and arborizing high endothelial venules together with numbers of small lymphocytes, eosinophils, plasma cells, and histiocytes in the background mimicked those of AITL, but did not completely fulfill the diagnostic criteria. Clonal analysis demonstrated that the specimen contained multiple LPDs of both B-cell and T-cell lineages. Sequence analysis confirmed the co-existence of a clone responsible for production of the abnormal heavy chain. This report provides new insights into the pathology of γ-HCD. Multiple host-derived factors (e.g., RA and/or use of MTX) may be responsible for the occurrence of LPDs of multiple lineages within a single lymph node..

A 64-year-old woman was diagnosed with AIP in 2007. The symptoms resolved with prednisolone (PSL). Although the dose of PSL was tapered to 7.5 mg/day for maintenance, serum IgG4 levels remained high. She suddenly presented with subcutaneous bleeding in 2015. Her activated partial thromboplastin time was prolonged (80.0 s). A mixing test showed an inhibitor pattern, factor VIII (FVIII) activity was less than 1%, and FVIII inhibitor was 290 BU/mL. She was diagnosed with AHA. Her serum IgG4 was elevated to 133 mg/dL. She was treated first with PSL alone, but she developed bladder tamponade. Cyclophosphamide and activated prothrombin complex concentrate were combined with PSL. She then achieved hemostasis, and FVIII inhibitor disappeared. FVIII inhibitor had been detected since PSL was tapered and AHA recurred two months later. An enzyme-linked immunosorbent assay showed that the inhibitor was mainly IgG4 and IgG1. This case suggests that elevation of IgG4 may be associated with the development of both AHA and AIP..

PATIENTS AND METHODS: Patients received up to 6 mEPOCH cycles. Etoposide (50 mg/m2/day), doxorubicin (10 mg/m2/day), and vincristine (0.4 mg/m2/day) were each given as a continuous 96-hour infusion on days 1 to 4. Prednisolone (40 mg/m2/day) was given intravenously or orally on days 1 to 4 and then tapered and stopped on day 7, and carboplatin (dose calculated for each patient individually using Calvert's formula according to a target under the curve of 3 mg/mL/min) was given as a 2-hour intravenous infusion on day 6. RESULTS: In 103 patients, overall response rate and complete response rate were 58% and 25%, respectively. With a median follow-up of 8.9 months, the median survival time was 9.8 months (95% confidence interval, 7.2-13.9 months). The median progression-free survival (PFS) was 4.2 months (95% confidence interval, 3.4-5.7 months). Patients who completed ≥ 4 cycles experienced significantly better overall survival and PFS compared with those who completed < 4 cycles. Twenty-eight patients underwent allogeneic hematopoietic stem cell transplantation after mEPOCH and demonstrated significantly prolonged overall survival and PFS compared with those who did not undergo transplantation. CONCLUSION: The mEPOCH regimen is effective with tolerable adverse effects and may be an alternative treatment option for adult T-cell leukemia/lymphoma..

However, the mechanism underlying innate immune detection leading to the priming of T cells is not fully understood, as H. pylori evades TLR detection. Here, we report that H. pylori metabolites modified from host cholesterol exacerbate gastritis through the interaction with C-type lectin receptors. Cholesteryl acyl α-glucoside (αCAG) and cholesteryl phosphatidyl α-glucoside (αCPG) were identified as noncanonical ligands for Mincle (Clec4e) and DCAR (Clec4b1). During chronic infection, H. pylori-specific T cell responses and gastritis were ameliorated in Mincle-deficient mice, although bacterial burdens remained unchanged. Furthermore, a mutant H. pylori strain lacking αCAG and αCPG exhibited an impaired ability to cause gastritis. Thus H. pylori-specific modification of host cholesterol plays a pathophysiological role that exacerbates gastric inflammation by triggering C-type lectin receptors..
