Here, we report a case of CNL with presence of the JAK2 sellekchem V617F mutation. After treatment with interferon alfa-2b with 3 million units every other day for 1 month, the patient’s white blood cell count was well controlled below 10.0 x 10(9)/l. At present, our patient remains symptomatically well and is maintained on interferon alfa-2b (3 million units twice a week), and his neutrophil count now averages around 8.0-10.0 x 10(9)/l.

BK virus-associated hemorrhagic cystitis (BKV-HC) is a severe complication after allogeneic hematopoietic stem cell transplantation. So far, no specific antiviral drug with proven efficacy has been approved for treating BKV-HC. Leflunomide is an immunosuppressive drug with antiviral activity and has been used in treating BKV-associated nephropathy after renal transplantation.

This is the first report on the efficacy and safety of leflunomide in the treatment of BKV-HC. From January 2006 to January 2009, 89 patients received allogeneic hematopoietic stem cell transplantation, and among them, 18 patients were identified as having BKV-HC, with a 20% cumulative incidence. Fourteen patients were treated with oral leflunomide. Three days of 100 mg/day leflunomide was used as loading doses and followed by maintenance doses of 20 mg/day. The urinary BKV-DNA load was monitored weekly by real-time quantitative PCR. The efficacy was evaluated on day 20 after leflunomide treatment. Seven patients (50%) achieved complete remission, 5 patients (35.7%) achieved partial remission, and 2 patients (14.

3%) had more than a 1-log reduction in urinary BKV-DNA loads after treatment. During the Carfilzomib leflunomide treatment, the graft-versus-host disease of the patients did not progress, and the dosages of the immunosuppressant were reduced simultaneously. One patient discontinued treatment because of intolerable gastrointestinal symptoms. Neutropenia occurred in 2 cases. These preliminary data suggest that leflunomide may be a potentially effective medication for treating BKV-HC without significant toxicity, but evidence supporting its use requires randomized controlled trials.

The “acid mantle” is a topic not only of historical interest, but also of clinical significance and has recently been linked to vital stratum corneum function. Despite compelling basic science evidence placing skin pH as a key factor in barrier homeostasis, stratum corneum integrity, and antimicrobial defense, application of the acid mantle concept in clinical care is lacking. We review recent basic science investigations into skin pH, discuss skin disorders characterized by aberrant pH, and finally discuss practical application for preservation of the acid mantle.
