ABSTRACT

BACKGROUND@#Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis.@*METHODS@#We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12.@*RESULTS@#The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported.@*CONCLUSION@#During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR), ChiCTR-TRC-13003259; http://www.chictr.org.cn/showprojen.aspx?proj=6300.

ABSTRACT

BACKGROUND@#Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.@*METHODS@#This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12.@*RESULTS@#A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period.@*CONCLUSION@#Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03066609; https://clinicaltrials.gov/ct2/show/record/NCT03066609.

ABSTRACT

Objective:To study the effect of modified Shaoyao Gancao Tang on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease model mice. Method:The sixty C57/BL6 mice were randomly divided into normal group, model group, Madopar group (50 mg·kg-1) and low, medium and high doses modified Shaoyao Gancao Tang (1,2,4 g·kg-1). The modeling method was to intraperitoneally inject C57/BL6 mice with MPTP(40 mg·kg-1) once a day for 7 days. Except normal group and model group were given normal saline daily,drug-administered group was intragastrical administered once a day, and the third day after the drug was administered according to the above method (except normal group). The behavior of each group of mice (climbing test, swimming test, and tail suspension test) was examined up to 15 days after administration. Subsequently, the levels of Cystatin-C (Cys-C) and neuron-specific enolase (NSE) in the serum of each group were detected by enzyme-linked immunosorbent assay (ELISA). The levels of superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) in striatum of each group were detected by spectrophotometry. The protein expression of α-synuclein (α-syn), tyrosine hydroxylase (TH),B lymphoma-2 gene (Bcl-2) and Bcl-2 related X protein (Bax) in the striatum of each group was detected by Western blot. Result:Compared with normal group, the swimming experiment scores and suspension experiments scores in the behavioral experiments of model group mice were significantly lower (PPPPPPPα-syn and Bax expression in striatum were significantly increased (PPPPPPPPα-syn and Bax expression in striatum were significantly decreased (PPPPPPPPα-syn expression and Bax expression in the striatum were significantly decreased (PConclusion:The neuroprotective effect of modified Shaoyao Gancao Tang on MPTP-induced Parkinson's disease model mice may be achieved by inhibiting oxidative damage and apoptosis.

ABSTRACT

<p><b>BACKGROUND</b>Candida albicans (C. albicans) can become a pathogen causing superficial as well as life-threatening systemic infections, especially in immunocompromised patients. Many phenotypic attributes contribute to its capacity to colonize human organs. In our study, 93 C. albicans isolates from patients of various candidiasis in a hospital of China were surveyed. We aimed to investigate the white-opaque (WO) switching competence, drug sensitivity, and virulence of mating type-like (MTL) a/α isolates.</p><p><b>METHODS</b>Internal transcribed spacer (ITS) gene and the MTL configuration were detected in all the isolates by reverse transcription-polymerase chain reaction. White/opaque phenotype and doubling time of cell growth were determined. The minimum inhibitory concentrations of antifungal agent were measured using broth microdilution method.</p><p><b>RESULTS</b>Sixty-four isolates (69.6%) were classified to serotype A, 19 (20.6%) to serotype B, and 9 (9.8%) to serotype C. Moreover, phylogenetic analysis showed that these isolates were divided into four different subgroups of ITS genotypes. Most of our clinical isolates were MTL a/α type, while 6.8% remained MTL a or MTLα type. The frequency of opaque phenotype was 71.0% (66 isolates). Following the guidelines of Clinical and Laboratory Standards Institute M27-A3, all isolates were susceptible to caspofungin and a few (0.6-3.2%) of them showed resistance against amphotericin B, flucytosine, fluconazole, itraconazole, and voriconazole.</p><p><b>CONCLUSIONS</b>From these analyses, there were comparatively more C. albicans strains classified into serotype B, and the frequency of opaque phase strains was significant in the clinical isolates from China. Genetic, phenotypic, or drug susceptibility patterns were not significantly different from previous studies. MTL a/α isolates could also undergo WO switching which facilitates their survival.</p>

ABSTRACT

<p><b>BACKGROUND</b>Invasive aspergillosis (IA), which is mainly caused by Aspergillus fumigatus (A. fumigatus), is a major cause of morbidity and mortality in immunocompromised patients. Despite considerable progress in currently available antifungals the mortality still remains high in critically ill patients. U0126 which is a highly selective inhibitor of MEK1 and MEK2 in the RAF/MEK/ERK pathway in mammalian cells has been demonstrated to have an anti-proliferative role in cancer cells. The purpose of this study was to explore the role of U0126 on growth inhibition and activation of mitogen-activated protein kinases (MAPKs) in A. fumigatus.</p><p><b>METHODS</b>Germination percentage and hyphae growth in A. fumigatus treated with U0126 were observed and compared with untreated controls. Western blotting analysis was used to detect changes in activation of SakA, MpkA and MpkB.</p><p><b>RESULTS</b>U0126 inhibited germination and hyphae growth in A. fumigatus and enhanced the phosphorylation of SakA and MpkA under oxidative stress. U0126 at 10 µmol/L did not block the activation of MpkB during nitrogen starvation stress.</p><p><b>CONCLUSION</b>U0126 shows promise as an antifungal candidate and the MAPK pathway may be a possible antifungal drug target for A. fumigatus.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the feasibility of PCR/reverse line blot hybridization (RLB) assay in the detection and identification of clinical pathogens in fungal sinusitis (FS).</p><p><b>METHODS</b>Twenty-six formalin-fixed and paraffin-embedded tissues and 8 fresh tissues of FS were collected from Beijing Tongren Hospital, Capital Medical University from May 2009 to February 2010. Pathological examination, fungal culture and ITS2 region sequencing were carried out. The DNA of all samples was extracted by standard procedure and fungal universal primers ITS3 and ITS4 were used for PCR amplification of all tissues. Then the amplified products were used for RLB with five fungal species-specific probes. The results of PCR/RLB were compared with ITS region sequencing, fungal culture and pathological examination.</p><p><b>RESULTS</b>For the biopsy tissues, fungal cultures were positive in 14 cases (41.2%); pathologic examination demonstrated fungal hyphae in all cases; ITS2 region sequencing was successful in 16 cases (47.1%); PCR/RLB showed A. flavus in 14 cases, A. fumigatus in 10 cases, A. niger in four cases, A. nidulans in one case, A. flavus and A. fumigatus in three cases, and A. fumigatus and A. niger in two cases.</p><p><b>CONCLUSIONS</b>The PCR/RLB assay is suitable for rapid and accurate detection and identification of the pathogenic fungus of FS. Compared with the conventional fungal culture and microscopy, pathologic examination and DNA sequencing, the PCR/RLB has the advantages of more economy, time saving, and higher sensitivity, specificity and throughput.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the value of cryptococcal latex agglutination test in the diagnosis and treatment of cryptococcal meningitis in children.</p><p><b>METHODS</b>The clinical data of 10 children with cryptococcal meningitis were retrospectively studied. Cryptococcal meningitis was confirmed based on clinical manifestations, India ink stain, cryptococcal latex agglutination test or cryptococcal culture. The outcome of antifungal treatment and the changes of latex agglutination test titer were followed up for 2 to 4 years.</p><p><b>RESULTS</b>Latex agglutination test and/or India ink stain were positive (titer 1 : 64-1 : 1024) in 8 patients in the first examination of cerebrospinal fluid. In the other 2 patients, latex agglutination test was positive (titer 1 : 256) in the fourth examination of cerebrospinal fluid in one, and India ink stain was positive in the eleventh examination in the other. After antifungal treatment, six patients were cured, two patients died, and two patients were lost to follow-up. The positive cryptococcal latex agglutination test (titer 1 : 2-1 : 16) was seen respectively in six, three, two and one cured patients 6 months, 1 year, 2 years and 4 years later.</p><p><b>CONCLUSIONS</b>The cryptococcal latex agglutination test of cerebrospinal fluid is valuable for the quick and early diagnosis of cryptococcal meningitis; however, the decision of withdrawal of antifungal treatment should not rely on the results of the test.</p>

ABSTRACT

<p><b>BACKGROUND</b>Glucocorticoid is speculated to be able to have Aspergillus fumigatus (A. fumigatus) being more susceptible to reactive oxygen species (ROS) by inhibiting Afyap1, the transcription factor activating protein-1 (AP-1) homologue in A. fumigatus, which may provide a clue to expand the clinical use of glucocorticoid in patients with fungal infections. In this study, we used dexamethasone to determine the direct effect on oxidative killing susceptibility of A. fumigatus in vitro, as well as the expression level of Afyap1 gene and its target genes (catalase and superoxide dismutase (SOD) genes).</p><p><b>METHODS</b>A. fumigatus spores were treated with different concentrations (0, 0.02, 0.2 mg/ml) of glucocorticoids and assigned to four groups (A: 0.5 hour, B: 2 hours, C: 7 hours, D: 16 hours) according to the time of treatment. The H2O2 oxidative killing assay was done, using the standard method-spot test, in each group of A. fumigatus. We measured the oxidative killing susceptibility as well as the expression level of the gene Afyap1, CATA, SOD1 and SOD2 in A. fumigatus at each group. The antifungal susceptibility to itraconazole and amphotericin B in each group of A. fumigatus was also measured with M38-A2 method.</p><p><b>RESULTS</b>The oxidative killing susceptibility of A. fumigatus was increased, consistent with the reduction of Afyap1, CATA, SOD1 and SOD2 gene expression level after being treated with dexamethasone for 0.5 hours. However, these observations were disappeared along with being treated for longer time. The antifungal susceptibility to itraconazole and amphotericin B in the A. fumigatus strains treated with dexamethasone indicated no change, compared with those without dexamethasone treatment.</p><p><b>CONCLUSION</b>Dexamethasone can have A. fumigatus being more susceptible to ROS when treated for shorter period (0.5 to 2 hours) via the reduction of Afyap1 gene expression as well as the down-stream enzyme-coding gene expression.</p>

ABSTRACT

<p><b>BACKGROUND</b>The cytochrome P450 lanosterol 14alpha-demethylase (Erg11p) encoded by ERG11 gene is the primary target for azole antifungals. Changes in azole affinity of this enzyme caused by amino acid substitutions have been reported as a mechanism of azole antifungal resistance. This study aimed to investigate the relationship between amino acid substitutions in Erg11p from fluconazole resistant Candida albicans (C. albicans) isolates and their cross-resistance to azoles.</p><p><b>METHODS</b>Mutations in ERG11 gene were screened in 10 clinical isolates of fluconazole resistant C. albicans strains. DNA sequence of ERG11 was determined by PCR based DNA sequencing.</p><p><b>RESULTS</b>In the 10 isolates, 19 types of amino acid substitutions were found, of which 10 substitutions (F72S, F103L, F145I, F198L, G206D, G227D, N349S, F416S, F422L and T482A) have not been reported previously. Mutations in ERG11 gene were detected in 9 isolates of fluconazole resistant C. albicans, but were not detected in 1 isolate.</p><p><b>CONCLUSIONS</b>Although no definite correlation was found between the type of amino acid substitutions in Erg11p and the phenotype of cross-resistance to azoles, the substitutions F72S, F145I and G227D in our study may be highly associated with resistance to azoles because of their special location in Erg11p.</p>

ABSTRACT

<p><b>BACKGROUND</b>Invasive pulmonary aspergillosis (IPA) is a severe and frequently fatal disease in patients receiving treatment with immunosuppressive agents such as cyclophosphamide. Aspergillus fumigatus (A. fumigatus) now is a leading cause of IPA. Dectin-1 and Toll-like receptor 2 (TLR2) are important pattern recognition receptors involved in immune responses to A. fumigatus in vitro. However, the expression of the two receptors during the infection of A. fumigatus in vivo is not completely understood. The effects of cyclophosphamide treatment on the expression of the receptors need to be further studied.</p><p><b>METHODS</b>We established different immune status in mice models with or without A. fumigatus infection. On days 1, 3 and 5 post inoculation, pulmonary tissues from mice of the different groups were harvested. Dectin-1 and TLR2 mRNA expression in the lungs of the mice were investigated by real-time PCR. The pulmonary fungal burden in the mice with A. fumigatus infection was also evaluated.</p><p><b>RESULTS</b>In the immunocompetent mice, three days after A. fumigatus inoculation, dectin-1 and TLR2 expression increased markedly compared with the normal control group. Cyclophosphamide inhibited the clearance of pathogens and the expression of dectin-1 with or without A. fumigatus infection in the lungs as well. There was no statistical difference in TLR2 expression between the different immune status groups.</p><p><b>CONCLUSIONS</b>Our results suggest that in vivo, dectin-1 and TLR2 are activated during the experimental period which would provide a broad range of possibilities for a specific and effective inflammatory response to kill A. fumigatus. Inhibition of dectin-1 expression may be one of the mechanisms of cyclophosphamide in the development of IPA.</p>

ABSTRACT

Objective To explore the clinical characteristics ,diagnosis, treatment and prognosis of phaeohyphomycosis. Methods Clinical data were collected, including history, physical examination, cranial and spinal imaging. Brain biopsy was performed. Data of the pathology and incubation of brain tissue were analyzed. Responsiveness to treatment was followed up. Results A previously healthy three and half years old boy was presented to our unit, with a three- month history of recurrent headache, vomiting, progressive paraplegia accompanied by urinary continence and constipation. A computed tomogram scan and magnetic resonance imaging of the brain revealed multiple lesions located in the region of the parietal - occipital lobes, periventricular area and frontal lobe, with prominent surrounding edema and irregular peripheral enhancement of the mass after the administration of contrast materials. A cerebral biopsy was performed and the pathological report was cerebral phaeohyphomycosis. The culture of the tissue and cerebrospinal fluid grew a same fungus identified as exo-phiala dermatitidis. The patient's response to therapy was poor, the parents of the boy gave up therapy, and the boy died 1 month later. Conclusions Cerebral Phaeohyphomycosis caused by Exophiala dermatitidis is rare, but the most serious form of fungus infection. Pathology and incubation of the tissue are essential for diagnosis. There is no curative therapy and the prognosis is poor.

ABSTRACT

In recent years,with the increasing of immunocompromised patients in clinical practice,invasive candidiasis has been increased accordingly. Although several antifungal drugs,including polyenes,azoles,5-flucytosine,and echinocandins,have been used widely to treat invasive candidiasis,the treatment failure that caused by the resistance of Candida albicans to these antifungal drugs have been reported widely. Here,we reviewed the molecular mechanisms of resistance to azoles,polyenes,5-flucytosine,and echinocandins,such that to provide an update on these issues.
