ABSTRACT
Objective To investigate clinical efficacy of the NB-UVB phototherapy combined with calcipotriol ointment and halometasone cream in the treatment of psoriasis.Methods 90 patients with psoriasis were selected and randomly divided into control group and observation group with 45 cases of patients.In both two groups,calcipotriol ointment,1 time/d,were used combined with halometasone cream,1 time/d,with a total of 4 weeks.On the basis of these,patients of observation group were added NB-UVB phototherapy (Germany Waldmann7001K ultraviolet light therapy device),1 time every other day with starting dose of 0.5J/cm2,each increment of 0.1J/cm2,for treatment of 15 times.Before and after treatment in patients of two groups,PASI score and clinical efficacy were observed.Visual analogue scale (VAS) were was used to observe itching skin lesions before and after treatment.By using Dermatology Life Quality Index (DLQI),qualities of life in two groups of patients before and after treatment were evaluated.observe two patients before and after treatment expression levels of serum IL-17A,IL-22 and IL-1βwere also observed in patients of the two groups.Results The total efficiency of the observation group was 88.89％,which of the control group was 80.00％,the clinical efficacy of the observation group which was higher than that of the control group,and the difference was statistically significant (x2 =5.23,P ＜ 0.05).Before treatment,the difference of PASI,VAS score and DLQI in the two groups of patients were not statistically significant (P ＞ 0.05).After treatment,scores in the two groups of patients were significantly decreased,and the degree of decrease in the observation group was higher than the control group,the difference was significant (P ＜ 0.05).Before treatment,the differences in serum IL -17A,IL-22 and IL-1β expression levels of both two groups were not statistically significant (P ＞0.05).After treatment,these expression levels of the two groups of patients decreased significantly,and the decreased of observation group was more significantly than that of the control group (P ＜ 0.05).Conclusion NB-UVB phototherapy combined with calcipotriol ointment and halometasone cream in treatment of psoriasis vulgaris patients can significantly improve patients' skin lesions,and can improve patients' quality of life score,which is worthy of promotion.
ABSTRACT
Aim TodevelopandvalidateaLC-MS/MS assay to quantify halometasone in rabbit plasma and study pharmacokinetics of halometasone after dermal topical administration of Halometasone Cream.Meth-ods Theplasmasamplewassubmittedtoliquid-liquid extraction using methyl tertiary butyl ether,with dexa-methasone as the internal standard (IS ).Chromato-graphic separations were performed on a Diamonsil C18 column(100 mm ×4. 6 mm,5 μm)with a linear gra-dient of methanol and 2 mmol · L-1 ammonium ace-tate.Halometasone and dexamethasone(IS)were ion-ized with an ESI source operated in negative ion mode, and the detected ions were m/z 503. 1→413. 0 (halo-metasone),m/z 391. 0→361. 0 (dexamethasone ). The test article could be monitored in rabbit plasma when following single dermal topical administration of Halometasone Cream at 1 g/100 cm2 to rabbits by u-singavalidatedLC-MS/MSassay.Results Calibra-tion curve was linear over the concentration range of0. 02~20 μg·L-1 in rabbit plasma.For low,medi-um,high concentration of QC solutions,the intra-and inter-day precision was in the range of 3. 72% ~7. 87%, and the accuracy was within 99. 1% to 103%. The pharmacokinetic parameters in rabbits were as follows:Tmax,Cmax,AUC0-t,T1/2 was (7. 38 ± 1. 06)h,(1. 16 ±0. 527)μg·L-1,(18. 8 ±7. 23)h·μg·L-1 ,(13. 8 ±3. 70)h,respectively.Conclusions ThisLC-MS/MSanalysismethodhashighsensitivi-ty,and sample processing method is simple,which has been rigorously validated.The method could be suc-cessfully applied to the pharmacokinetic study of halo-metasone after skin administration of Halometasone Cream to rabbits.
ABSTRACT
Objective To observe the efficacy and safety of fusidic acid cream and halometasone cream in the treatment of psoriasis vulgaris.Methods Fifty-four patients with psoriasis vulgaris were enrolled in this study and were divided into observation group and control group.26 patients in observation group were treated with halometasone cream,28 patients in control group were treated with fusidic acid cream combined with halometasone cream.The psoriasis area and severity index (PASI) and abverse events of treatment were recorded.At the same time,34 normal people taking physical examination were selected as health group,the infections of pathogenic microorganism were compared between psoriasis vulgaris patients and normal people.Results The pathogenic infection rate of patients with psoriasis vulgaris was 72.22％,the infection rate was 75.00％ in observation group and 69.23％ in control group.The infection rate in health group was 38.24％,the difference in the pathogenic infection rate was statistically significant between paitents with psoriasis vulgaris and normal people (P ＜0.05).After treatment,the rate of negative infections was 95.24％ in observation group and 72.22％ in control group,there was significant difference between two groups (P＜0.05).The PASI scores and VAS scores of observation group were significantly lower than those of control group (P＜0.05).The total effective rate of treatment was 71.43％ in observation group and 34.62％ in control group,the difference was statistically significant (P＜0.05).There was no significant difference in rate of adverse events between observation group and control group (P ＞0.05)Conclusion The pathogenic infection is closely correlated with psoriasis vulgaris,fusidic acid cream combined with halometasone cream has good efficacy and safety in treatment of psoriasis vulgaris and worth of popularization and application.
ABSTRACT
Aim To study the effect of halometasone in combination with scutellaria baicalensis georgi on the vitiligo mice induced by monobenzone. Methods 40% monobenzone cream was applied to induce vitiligo in C57BL/6 mice. Through the halometasone, halo-metasone and scutellaria baicalensis georgi combined with 40% monobenzone cream, the influence of halo-metasone and scutellaria baicalensis georgi on mice de-colorizing was studied. Hair decolorizing was observed with the naked eye, the skin decolorizing was observed by reflectance confocal microscopy ( RCM ) , and CD8 +T cell infiltration was tested with immunofluores-cence detection. The serum levels of interleukin-6(IL-6 ) and tumor necrosis factor-α( TNF-α) were deter-mined by enzyme linked immunosorbent assay ( ELISA) . Results Mice in model group showed de-pigmentation at both the monobenzone application part and non-application part. The halometasone group did not show significant therapeutic efficacy. In halometa-sone and scutellaria baicalensis georgi treatment group, there was less decolorization, the occurrence ratio, the scores of occurring time and size were lower compared with model group. There were fewer infiltrated lympho-cytes and CD8 +T cells. Halometasone and scutellaria baicalensis georgi group also showed that the serum levels of IL-6,TNF-α decreased. Conclusion Halo-metasone and scutellaria baicalensis georgi have thera-peutic effect on vitiligo mice induced by monobenzone.
ABSTRACT
[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.
