0 BU/ml. Based on these findings, the patient was finally diagnosed of acquired factor V inhibitor. One month after prednisolone administration at 20 mg/day, the PT and APTT were normalized, and prednisolone was tapered off. Although the use of dabigatran has been associated with iatrogenic acquired factor V inhibitor, we describe the first case of acquired factor V inhibitor associated with direct Xa inhibitor.A 76-year-old male with lower-limb weakness was admitted to our hospital where thrombocytopenia and anemia were noticed. CT showed massive splenomegaly and multiple nodules inside the spleen. Bone marrow examination showed an increase of macrophages with large cytoplasm. Suspected of splenic lymphoma, the patient underwent splenectomy. Spleen specimens were histologically analyzed and suggested the probability of Gaucher's disease (GD). Leukocyte glucocerebrosidase (GBA) enzyme activity had decreased to 1.25 nmol/mg, and mutation analysis of GBA revealed two missense variants, p.D448H (D409H), p.L483P (L444P), which confirmed the diagnosis of type I GD. Fourteen months after splenectomy, he developed right buttock pain, and pelvic magnetic resonance imaging showed a fragile right pubic and pelvic fracture. We initiated injection of imiglucerase as enzyme replacement therapy (ERT) and administered bisphosphonate. His symptoms gradually improved without surgical treatment. In addition, thrombocytopenia and anemia also improved, and angiotensin-converting enzyme levels decreased. Type I GD should be considered a differential diagnosis of giant splenomegaly and thrombocytopenia, even in the elderly. ERT or substrate reduction therapy should be administrated to GD patients, while paying attention to the development of bone lesions.Venetoclax, a selective BCL-2 inhibitor, is prescribed clinically for acute myeloid leukemia (AML) treatment.  https://www.selleckchem.com/products/azd9291.html  However, it is unclear if known chromosomal or genetic abnormalities associated with AML also influence BCL-2 expression. Few studies have examined BCL-2 expression in AML-related precursor neoplasms such as primary myeloid sarcoma (MS) and blastic plasmacytoid dendritic cell neoplasm (BPDCN). In this study, we examined BCL-2 expression using immunohistochemistry in 7 patients with AML, who also carried genetic and chromosomal abnormalities typical to AML including t (8;21), t (15;17), FLT3-ITD mutation, and complex karyotype, along with 1 patient with primary MS and 3 patients with BPDCN. As a result, expression of BCL-2 was observed in all patients with AML and 1 patient with primary MS. In the patients with BPDCN, BCL-2 was highly expressed in all regions with evidence of tumor cell infiltration, such as skin, bone marrow, and lymph node. These results could be used as evidence in the support of administering venetoclax to adverse-risk patients with AML, MS, or BPDCN.Glomerular inflammation is a putative aggravation factor for type 2 diabetic nephropathy and urinary thrombin is a novel marker of glomerular inflammation. To clarify the relationship between glomerular inflammation and progression of the nephropathy, we measured urinary thrombin in 118 patients with type 2 diabetic nephropathy at different stages. To investigate the implications of urinary thrombin in the nephropathy, we compared urinary thrombin with expression of tissue factor, the trigger of blood coagulation activation, in glomeruli and with markers of renal injury (estimated glomerular filtration rate (eGFR) and proteinuria). Urinary thrombin was found in 4.9% (3/61), 0.0% (0/12), 29.6% (8/27) and 50.0% (9/18) of patient groups at stages 1, 2, 3 and 4, respectively. Thus, urinary thrombin was negligible in the patients at early stages (stages 1 and 2), but was present predominantly in the patients at advanced stages (stages 3 and 4). Tissue factor was expressed in accumulated macrophages in glomeruli, which indicates that thrombin may be generated in inflamed glomeruli presumably via inflammation-induced activation of the exudated coagulation factors into glomerular tissues and then be excreted in urine. Urinary thrombin was significantly associated with both decreased eGFR and increased proteinuria in type 2 diabetic nephropathy. Therefore, increased urinary thrombin in patients with advanced stages of type 2 diabetic nephropathy suggests that glomerular inflammation may injure the tissues, thereby impairing renal function. Monitoring an effect of anti-diabetic treatments on glomerular inflammation in the patients with type 2 diabetic nephropathy may be a possible application of urinary thrombin.In esophageal squamous cell carcinoma (ESCC) comprising 90% of cases with esophageal cancer, endoscopic resection (ER) is recommended for patients with negligible risk of ESCC-related mortality. In fact, a main cause of death in patients underwent ER is not ESCC. We thus aimed to clarify the predictors for early and late mortality among patients underwent ER of ESCC between 2005 and 2018 at our institution. In this retrospective cohort study, we investigated the prognosis and predictors of early and late mortality with the cut-off value of 3 years. We enrolled 407 patients with a median 69 months follow-up. The 5-year overall survival and disease-specific survival, an indicator of ESCC-related mortality, were 83.4% and 98.4%, respectively. In multivariate Cox analyses, Eastern Cooperative Oncology Group performance status (ECOG-PS), consisting of six grades by a patient's level of activity, ≥ 2 was a predictor for early and late morality [hazard ratio (HR), 7.21 (P = 0.007) and 15.62 (P = 0.021), respectively]. Charlson comorbidity index (CCI), which is an index for predicting mortality by comorbid conditions, ≥ 2 was also a predictor for both mortality [HR, 2.97 (P = 0.017) and 1.90 (P = 0.019), respectively]. However, age was a predictor only for late mortality [HR, 3.08 (P = 0.010) in 80-84 years and 8.38 (P less then 0.001) in ≥ 85 years]. Considering the predictive ability for early mortality, we propose that ECOG-PS and/or CCI are better indices compared with age in deciding treatment strategy after ER for ESCC.Juvenile idiopathic arthritis (JIA) is a heterogeneous autoimmune disease characterized by arthritis of unknown etiology. JNK pathway-associated phosphatase (JKAP) is reported to be a negative regulator of T-cell activation, but its clinical role in JIA is unknown. This study aimed to investigate the correlation of JKAP with disease activity and treatment response to a tumor necrosis factor (TNF) inhibitor, etanercept (ETN), in JIA patients. Totally, 104 JIA patients (6.9 ± 2.7 years old) and 100 age- and sex-matched healthy controls (HCs) (7.2 ± 2.4 years old) were enrolled, and their serum samples were collected for measuring JKAP by enzyme-linked immunoassay. In JIA patients, after 24-week ETN treatment, clinical response was assessed based on the American College of Rheumatology pediatric criteria (ACRpedi) 50 criteria. Results showed that JKAP levels were significantly lower in JIA patients compared with HCs, and of good value in differentiating JIA patients from HCs. Among JIA patients, higher JKAP levels were associated with lower disease activity indexes, including C-reactive protein, number of joints with active arthritis, physician's global assessment of disease activity, and the present history of disease-modifying antirheumatic drugs; higher baseline JKAP levels were correlated with worse ACRpedi 50 response to ETN at week 24, and was also an independent predictive factor for worse ACRpedi 50 response to ETN.
