Toenail onychomycosis is a common disease that can have serious adverse effects on the quality of life (QOL) of patients.', 'To evaluate the impact of itraconazole pulse therapy on the QOL of patients with toenail onychomycosis.', 'A total of 20 patients with disto-lateral subungual toenail onychomycosis were treated with itraconazole 200 mg twice daily for 1 week every 4 weeks for 12 weeks. The patients were asked to complete a QOL questionnaire before treatment and on the last follow-up visit (week 48). A score of 0-4 was given according to the five possible responses to each question and these were summed to give the final score of the patient. The mean of the final scores of the patients before and after treatment were compared using the Wilcoxon matched-pairs test.', 'At 48 weeks after commencing treatment, 14 patients (70%) responded to treatment (nine patients were cured with almost totally clear toenails and five patients improved), and 16 patients (80%) were mycologically cured (negative KOH smear and culture). The mean of the QOL scores of the patients before treatment was 18.0+/-7.8, which reduced to 13.1+/-11.3 after treatment (two-tailed, p=0.009).
Does itraconazole pulse therapy improve the quality of life of patients with toenail onychomycosis?

GM-CSF has broad clinical applicability as a potent myelopoietic stimulator. However, its function is not restricted to the myelopoietic system and several observations suggest that GM-CSF may interfere with the hemostatic balance. In order to assess whether GM-CSF has any influence on hemostasis, we evaluated some coagulative and fibrinolytic parameters in patients treated with GM-CSF following chemotherapy.', 'Fibrinolytic activity (FA), fibrinogen and D-dimer were evaluated before and after high-dose cyclophosphamide in 6 patients additionally treated with GM-CSF and in 5 control patients; moreover, tissue plasminogen activator (tPA) was assayed in those treated with GM-CSF. Comparative in vitro analysis was performed on cultured endothelial cells before and after exposure to GM-CSF.', 'Control patients showed a significant decrease in plasma FA after chemotherapy compared to basal values (FA/mm2: 15.6 +/- 2.1 at day + 2 and 20.8 +/- 19 at day + 4 vs. 103.8 +/- 64.2 at day 0; p < 0.005); conversely, no FA reduction was observed in GM-CSF-treated subjects. In this latter group a marked increase in tPA antigen was seen, consistent with enhanced FA. No significant changes in plasma D-dimer and fibrinogen values were detected in the two groups. tPA, urokinase-type plasminogen activator, PAI-1 and procoagulant activity were evaluated in vitro on cultured human endothelial cells and found to be unchanged following GM-CSF addition.
Is reduction of plasma fibrinolytic activity following high-dose cyclophosphamide neutralized in vivo by GM-CSF administration?

To determine interrelationships between the expression of long intergenic (noncoding) RNA-p21 (lincRNA-p21), NF-κB activity, and responses to methotrexate (MTX) in rheumatoid arthritis (RA) by analyzing patient blood samples and cell culture models.', 'Expression levels of long noncoding RNA and messenger RNA (mRNA) were determined by quantitative reverse transcription-polymerase chain reaction. Western blotting and flow cytometry were used to quantify levels of intracellular proteins. Intracellular NF-κB activity was determined using an NF-κB luciferase reporter plasmid.', 'Patients with RA expressed reduced basal levels of lincRNA-p21 and increased basal levels of phosphorylated p65 (RelA), a marker of NF-κB activation. Patients with RA who were not treated with MTX expressed lower levels of lincRNA-p21 and higher levels of phosphorylated p65 compared with RA patients treated with low-dose MTX. In cell culture using primary cells and transformed cell lines, MTX induced lincRNA-p21 through a DNA-dependent protein kinase catalytic subunit (DNA PKcs)-dependent mechanism. Deficiencies in the levels of PRKDC mRNA in patients with RA were also corrected by MTX in vivo. Furthermore, MTX reduced NF-κB activity in tumor necrosis factor α-treated cells through a DNA PKcs-dependent mechanism via induction of lincRNA-p21. Finally, we observed that depressed levels of TP53 and lincRNA-p21 increased NF-κB activity in cell lines. Decreased levels of lincRNA-p21 did not alter NFKB1 or RELA transcripts; rather, lincRNA-p21 physically bound to RELA mRNA.

Does methotrexate inhibit NF-κB activity via long intergenic ( noncoding ) RNA-p21 induction?
