ABSTRACT
Objective:To evaluate the therapeutic effect of intense pulsed light on rosacea.Methods:From December 2022 to April 2023, the Dermatology Department of the Affiliated Hospital of Shaanxi University of Chinese Medicine searched PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP, CBM and other Chinese and English databases to collect clinical randomized controlled studies on intense pulsed light treatment of rosacea for ameta-analysis.Results:A total of 559 patients were included in 6 randomized controlled trials. The efficacy of the combination of strong pulsed light and medication in the treatment of rosacea was significantly better than that of medication alone ( Z=6.15, P<0.001). After subgroup analysis, the combination of strong pulsed light and tetracycline drugs was more effective in treating rosacea than using tetracycline drugs alone ( Z=3.17, P<0.05). The efficacy of the combination of strong pulsed light and minocycline in the treatment of rosacea was better than that of minocycline alone ( Z=2.37, P<0.05), and clinical evaluation showed the improvements of erythema, papules, and pustules. The differences in scores for itching and capillary dilation were statistically significant ( P<0.05). Conclusions:The efficacy of intense pulsed light therapy for rosacea is definite, and its combination with topical or oral medication is superior to that of medication alone. However, the stability of the effect needs to be confirmed by more high-quality randomized controlled trials.
ABSTRACT
OBJECTIVE:To investigate the characteristics and rules of new and severe ADR induced by TCM for removing blood stasis and clearing heat in our hospital,and to provide reference for safe drug use in clinic. METHODS:New and severe ADR induced by TCM for removing blood stasis and clearing heat reported to national ADR monitoring center were collected from our hospital during Jan. 2006-Dec. 2016. Those ADR cases were analyzed retrospectively in respects of gender,age,allergic history,route of administration,drug type and dosage form,occurrence time,organs/systems involved and clinical manifestations, outcome. RESULTS:Among 298 reports,the incidence of ADR in female(70.13%)was higher male(29.87%),especially in patients aged 50-59(21.48%);there were 77 allergic cases(25.84%). Route of administration was mainly oral administration (57.37%),and dosage form was mainly injection(25.50%). Main ADR-inducing drug was Chinese patent medicine(53.53%). ADR mostly occurred over 1 d after medication(48.32%). Systems/organs involved in ADR were mainly lesion of skin and its appendants,systemic damage and gastrointestinal damage. Main clinical manifestations were rash,contact dermatitis,pruritus, infusion reaction,chills,fever,nausea,vomiting,diarrhea,etc.After drug withdrawal or symptomatic treatment,97.99% patients were revered and cured. There was no death case. CONCLUSIONS:TCM for removing blood stasis and clearing heat causes most new and severe ADR.Clinical drug use should be monitored closely to reduce the occurrence of ADR.
