    ABSTRACT: We report a 67-year-old woman who was diagnosed with hepatic portal venous gas associated with severe graft-versus-host disease (GVHD) of the gastrointestinal tract. The patient received allogenic peripheral blood stem cell transplantation from a haploidentical son against Philadelphia chromosome-positive acute lymphocytic leukemia. The patient developed grade 3 intestinal GVHD on day 90 from the transplantation. On day 149, she presented septic shock and computed tomography (CT) scan revealed hepatic portal venous gas (HPVG); an ileocecal resection was performed immediately. The damage of gastrointestinal mucosa by GVHD resulted in the invasion of gas-producing bacteria. Although HPVG-associated gastrointestinal GVHD is extremely rare, we should pay special attention to this pathogenesis.

    ABSTRACT: A 58-year-old woman was admitted to our hospital because of fever, systemic lymphadenopathy with abnormal Epstein-Barr virus (EBV) antibody titers, and a high EBV-DNA load in the serum. She had been diagnosed as possibly having chronic active EBV infection (CAEBV) during a previous hospitalization. The EBV-DNA load of the plasma (pEBV-DNA), examined at our hospital, was elevated to 1.8×10(4) copies/ml, whereas that of the peripheral blood mononuclear cells was 3.4×10(1) copies/μg DNA, which was not clearly elevated, unlike in cases with CAEBV. Biopsy of the cervical lymph node was performed and the diagnosis of mixed cellularity classical Hodgkin lymphoma, Stage4B was made. Hodgkin cells were positive for EBV. COPP therapy was started and pEBV-DNA decreased drastically. The treatment was followed by ABVD therapy and pEBV-DNA turned negative after one course of ABVD therapy. She achieved complete response after 4 courses of the treatment. Reports from abroad indicate that pEBV-DNA parallels the disease state of EBV-positive Hodgkin lymphoma. Our results were consistent with these reports, and demonstrated that, in a Japanese patient, EBV-DNA load and its localization in the peripheral blood fractions could be useful tools for diagnosis as well as evaluating the disease status.

    ABSTRACT: We report the case of a 68-year-old man who was diagnosed with Fournier's gangrene (FG), which developed during immunosuppresive treatment for idiopathic thrombocytopenic purpura (ITP). The patient was administered steroids for ITP but on the 36th day, he developed FG and septic shock. We initiated antibiotic treatment and drained a periproctal abscess immediately. On day 53, extensive drainage to progressive FG and a splenectomy was performed, following which both FG and thrombocytopenia improved. This is the first case of FG has developing in a ITP patient. It appears that high-dose immunoglobulin therapy and splenectomy should be considered earlier especially for a patient complicated with FG.

    ABSTRACT: Quantitative assay for serum free light chains (sFLC) is reported as a useful test for diagnosis and monitoring of patients with nonsecretory multiple myeloma (NSM). We performed serial sFLC assays in a patient with NSM with light chain cast nephropathy (LCCN) and light chain deposition disease (LCDD). After 3 cycles of VAD induction therapy, while plasma cells in the marrow decreased from 93.0% to 0.2%, sFLCkappa/lambda ratio remained abnormal. Flow cytometry assay also showed that these plasma cells were CD19 negative. After the subsequent high dose melphalan therapy followed by autologous peripheral blood stem cell transplantation (PBSCT), the sFLCkappa/lambda ratio returned to normal and the patient achieved a stringent complete response (sCR). One year after PBSCT, the patient remained in sCR with improved renal function. The quantitative FLC assay was useful for the diagnosis and monitoring of NSM and LCDD in this patient.
