Clinical Trial
Effects of irbesartan on inflammatory cytokine concentrations in patients with chronic glomerulonephritis.
Some angiotensin receptor blockers (ARBs), including irbesartan, increase the peroxisome proliferator-activated receptor (PPAR)-g activity in vitro. The aim of this study was to evaluate the interactions between obesity and the effects of irbesartan on inflammatory cytokines in chronic glomerulonephritis patients without diabetes. ⋯ Irbesartan improves metabolic parameters in nondiabetic hypertensive chronic glomerulonephritis patients, especially those with a high BMI. Improving the adiponectin concentration may be important for reducing proteinuria.

Case Reports
Papillary squamous cell carcinoma of the trachea associated with human papillomavirus-18 infection.
A 75-year-old man presented with the chief complaints of coughing and dyspnea. Chest computed tomography revealed narrowing of the trachea. ⋯ Multiplex polymerase chain reaction confirmed human papillomavirus type 18 DNA in the tumor. At the 12-month follow-up visit following the administration of radiotherapy, the patient exhibited no local recurrence or distant metastasis.

Type 1 autoimmune pancreatitis (AIP) is characterized by a high serum IgG4 concentration and is closely associated with the HLA-DRB1(*)04:05-DQB1(*)04:01 haplotype, for which family studies may disclose its immunogenetic significance. In the present study, we encountered two male siblings with type 1 AIP who exhibited diffuse pancreatic swelling with a capsule-like rim and diffuse pancreatic duct stricture. The younger brother also displayed characteristic IgG4-related sialadenitis and retroperitoneal fibrosis. Contrary to our expectations, the siblings showed only normal or slightly elevated values of serum IgG4 and no HLA DRB1(*)04:05-DQB1(*)04:01 haplotype, suggesting that type 1 autoimmune pancreatitis is associated with multiple immunogenetic factors.

We herein report the case of a 17-year-old man who developed an increased plasma creatinine level (11.1 mg/dL) and oliguria with massive proteinuria (27.3 g/day) four weeks after an abraded wound to his right knee. The histology of the renal biopsy specimens showed diffuse endocapillary proliferative glomerulonephritis with the deposition of nephritis-associated plasmin receptor in the glomerulus. A case of acute kidney injury due to nephrotic syndrome caused by acute post-streptococcal glomerulonephritis was diagnosed. His renal function and proteinuria were improved with supportive care, including hemodialysis, without the administration of immunosuppressive agents.

Community-acquired pneumonia (CAP) remains a major cause of death. No studies have reported the use of rapid influenza diagnostic tests (RIDT) for the etiological diagnosis, and the factors contributing to severity and mortality have not yet been fully investigated. The aim of this study was to review the etiologies of CAP using RIDT and to identify risk factors related to the severity and mortality of the disease. ⋯ In addition to S. pneumoniae, the influenza virus was a frequent cause of CAP overall and a frequent causative pathogen in both severe cases of CAP and non-survivors. Legionella spp. infection and polymicrobial infection were found to be an independent factor for the severity of CAP along with advanced age and certain comorbidities. An advanced age, certain respiratory comorbidities and severe CAP were found to be important independent factors for the mortality of CAP.
