Intensive Frequent Granulocyte Adsorptive Apheresis Therapy for Acute Fulminant Ulcerative Colitis: Two Consecutive Case Reports.

Granulocyte/monocyte adsorptive apheresis (GMA) therapy is a treatment method for ulcerative colitis (UC). Twice-weekly GMA regimens are usually administered to treat severe UC. Although GMA efficacy is considered frequency-dependent, there is no uniformly accepted optimal GMA regimen, and there is insufficient evidence regarding optimal GMA therapy frequency for acute fulminant UC.

Disseminated Bacillus Calmette-Guérin Infection with Rhabdomyolysis, Acute Kidney Injury, and Interstitial Pneumonia after Bacillus Calmette-Guérin Intravesical Instillation Therapy.

A 79-year-old man experienced a fever and immobility after receiving 6 doses of Bacillus Calmette-Guérin (BCG) intravesical instillation therapy for bladder tumor. Rhabdomyolysis and acute kidney injury occurred; therefore, hemodialysis was performed. His kidney function was restored.

Amplified EPOR/JAK2 Genes Define a Unique Subtype of Acute Erythroid Leukemia.

Unlabelled: Acute erythroid leukemia (AEL) is a unique subtype of acute myeloid leukemia characterized by prominent erythroid proliferation whose molecular basis is poorly understood. To elucidate the underlying mechanism of erythroid proliferation, we analyzed 121 AEL using whole-genome, whole-exome, and/or targeted-capture sequencing, together with transcriptome analysis of 21 AEL samples. Combining publicly available sequencing data, we found a high frequency of gains and amplifications involving EPOR/JAK2 in TP53-mutated cases, particularly those having >80% erythroblasts designated as pure erythroid leukemia (10/13).

Hypertensive Anaphylaxis After Moderna COVID-19 Vaccination: A Case Report.

Hypotension after exposure to an allergen is a well-known indicator of an anaphylactic reaction. However, hypertensive anaphylaxis often goes unrecognized. Increased blood pressure can present as an anaphylactic reaction, which is called hypertensive anaphylaxis.

Acute tubulointerstitial nephritis in a patient with early bronchial tuberculosis.

Patients with chronic kidney disease (CKD) are commonly at high risk of tuberculosis (TB). Conversely, TB rarely causes tubulointerstitial nephritis. A 75-year-old Japanese man who was undergoing periodic follow-ups for CKD stage G3aA3 with membranous nephropathy was diagnosed with acute kidney injury (AKI) (estimated glomerular filtration rate [eGFR]: 15 mL/min/1.

Anti-neutrophil cytoplasmic antibody-associated vasculitis accompanied by type II heparin-induced thrombocytopenia resulting in asymptomatic cerebral infarction: a case report.

Background: Heparin-induced thrombocytopenia (HIT) involves platelet activation and aggregation caused by heparin or HIT antibodies associated with poor survival outcomes. We report a case of HIT that occurred after hemodialysis was started for rapidly progressive glomerulonephritis (RPGN), which was caused by anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), and ultimately resulted in asymptomatic cerebral infarction.

Case Presentation: A 76-year-old Japanese man was urgently admitted to our hospital for weight loss and acute kidney injury (serum creatinine: 12 mg/dL).

Relationship Between Infection and Arteriosclerosis.

It is reported that () infection may be linked to non-digestive tract diseases, such as arteriosclerosis including dyslipidemia, diabetes, obesity, hypertension, and cardiovascular disease. Therefore, we reviewed recent studies available in PubMed dealing with the mechanisms of arteriosclerosis due to infection and the effects of eradication. Conventional studies suggested that infection may increase the risk of arteriosclerosis.

Health risk of travel for chronic kidney disease patients.

The number of people with chronic kidney disease (CKD) has increased and so has their demand for travel. However, the health risk posed by travel in these patients is unclear. Few reports document the travel risk in CKD and dialysis patients.

Efficacy of High-Dose Mycophenolate Mofetil in Multitarget Therapy for Lupus Nephritis: Two Consecutive Case Reports.

The complete remission rate for lupus nephritis (LN) is higher with multitarget therapy (MT) using tacrolimus (TAC), mycophenolate mofetil (MMF), and steroids than with steroid plus cyclophosphamide co-therapy. MT is also considered highly safe and is used to treat refractory LN. During MT, MMF is usually administered at a dose of 1 g/day similar to conventional MT; however, it remains unclear whether this is the optimal dose of MMF for Japanese patients, especially those refractories to conventional MT.

Non-urate transporter 1, non-glucose transporter member 9-related renal hypouricemia and acute renal failure accompanied by hyperbilirubinemia after anaerobic exercise: a case report.

Background: Renal hypouricemia (RHUC) is an inherited heterogenous disorder caused by faulty urate reabsorption transporters in the renal proximal tubular cells. Anaerobic exercise may induce acute kidney injury in individuals with RHUC that is not caused by exertional rhabdomyolysis; it is called acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE). RHUC is the most important risk factor for ALPE.

Successful management of visceral disseminated varicella zoster virus infection during treatment of membranous nephropathy: a case report.

Background: Visceral disseminated varicella zoster virus (VDVZV) infection is a rare disease with a high mortality rate (55%) in immunocompromised patients, but it is not yet widely recognized in the field of nephrology. We report a case of VDVZV contracted during immunosuppressive therapy for membranous nephropathy.

Case Presentation: A 36-year-old woman was diagnosed with membranous nephropathy and was being treated with immunosuppressive therapy consisting of 60 mg/day prednisolone, 150 mg/day mizoribine, and 150 mg/day cyclosporine.

Focal segmental glomerulosclerosis lesion associated with inhibition of tyrosine kinases by lenvatinib: a case report.

Background: Lenvatinib is a tyrosine kinase inhibitor with novel binding ability. It is considered the standard of care for metastatic thyroid cancer; moreover, whether it is indicated for other malignant tumors has been examined. Lenvatinib increases the risk of kidney injury in some patients.

Reduced Clearance of Phenobarbital in Advanced Cancer Patients near the End of Life.

Background And Objectives: Little is known about the pharmacokinetics of phenobarbital in terminally ill cancer patients. We investigated whether phenobarbital clearance alters depending on the length of survival.

Methods: We retrospectively reviewed the clinical, laboratory, and therapeutic drug monitoring (TDM) records of patients who received parenteral or oral phenobarbital for 21 consecutive days or longer between 2000 and 2016.

Membranoproliferative glomerulonephritis-like findings for TAFRO syndrome, associated with an anterior mediastinal tumor: A case report.

Rationale: TAFRO syndrome is a systemic inflammatory disease proposed recently from Japan. The cause of TAFRO syndrome is unclear. Moreover, the disease characteristics and kidney pathology are yet unknown well and there are few cases.

Final 3-year Results of the Dasatinib Discontinuation Trial in Patients With Chronic Myeloid Leukemia Who Received Dasatinib as a Second-line Treatment.

Introduction: We previously reported an interim analysis of the DADI (dasatinib discontinuation) trial. The results showed that 48% of patients with chronic myeloid leukemia in the chronic phase who maintained a deep molecular response (DMR) for ≥ 1 year could discontinue second- or subsequent-line dasatinib treatment safely at a median follow-up of 20 months. However, the results from longer follow-up periods would be much more useful from a clinical perspective.

Development of pancreatic cancer is predictable well in advance using contrast-enhanced CT: a case-cohort study.

Objectives: To investigate the radiological findings prognostic for the development of pancreatic adenocarcinoma in a cohort of patients with hepatocellular carcinoma, using multiphasic computed tomography (CT).

Methods: A case-cohort study performed in a single university hospital. A database of patients who received hepatocellular carcinoma (HCC) treatment and trimonthly follow-up with four-phase dynamic CT was used (n = 1848).

Randomized clinical trial of 24 versus 72 h antimicrobial prophylaxis in patients undergoing open total gastrectomy for gastric cancer.

Background: Open total gastrectomy carries a high risk of surgical-site infection (SSI). This study evaluated the non-inferiority of antimicrobial prophylaxis for 24 compared with 72 h after open total gastrectomy.

Methods: An open-label, randomized, non-inferiority study was conducted at 57 institutions in Japan.

A randomized, double-blind trial of pegfilgrastim versus filgrastim for the management of neutropenia during CHASE(R) chemotherapy for malignant lymphoma.

Pegfilgrastim is a pegylated form of the granulocyte-colony stimulating factor, filgrastim. Herein, we report the results of a multicentre, randomized, double-blind phase III trial comparing the efficacy and safety of pegfilgrastim with filgrastim in patients with malignant lymphoma. Patients were randomized to receive either a single subcutaneous dose of pegfilgrastim or daily subcutaneous doses of filgrastim on day 4 after the completion of cyclophosphamide, cytarabine, etoposide and dexamethasone ± rituximab (CHASE(R); day 1-3) chemotherapy.

Obesity with abundant subcutaneous adipose tissue increases the risk of post-ERCP pancreatitis.

Background/purpose: The risk factors for post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) have been widely investigated. However, studies focusing on the body mass index (BMI) and distribution of adipose tissue have not been reported. Therefore, we examined the correlation between PEP and these factors.

Discontinuation of dasatinib in patients with chronic myeloid leukaemia who have maintained deep molecular response for longer than 1 year (DADI trial): a multicentre phase 2 trial.

Background: First-line imatinib treatment can be successfully discontinued in patients with chronic myeloid leukaemia after deep molecular response has been sustained for at least 2 years. We investigated the safety and efficacy of discontinuing second-line or subsequent dasatinib after at least 1 year of deep molecular response.

Methods: The Dasatinib Discontinuation trial was a prospective multicentre trial done in Japan.

Prophylactic Efficacy of 3- or 5-cm Pancreatic Stents for Preventing Post-ERCP Pancreatitis: A Prospective, Randomized Trial.

Background And Study Aims: Prophylactic pancreatic stent placement is effective for preventing postendoscopic retrograde cholangiopancreatography pancreatitis (PEP). The most effective type of stent, however, remains unclear. Therefore, we prospectively compared the prophylactic efficacy for PEP prevention between short (3 cm) and long (5 cm) pancreatic stent.
