MicroRNA-155 is a potential predictive tool for atopic dermatitis severity in children: A preliminary study.

Atopic dermatitis (AD) is one of the most prevalent chronic inflammatory dermatological disorders in childhood. Assessment of AD severity is the initial step in designing the proper therapeutic plan. Moreover, it is imperative for evaluation of disease improvement during and following therapy. This study was designed to assess the prognostic role of miRNA-155 (miR-155) in the prediction of AD severity as the primary outcome. While the secondary outcome was to correlate the serum miR-155 expression levels with the scoring atopic dermatitis (SCORAD) severity index. This case-control study included 24 children with AD and 24 apparently healthy children as a control group. AD children were stratified according to the SCORAD severity index. Approximately 58% of children had mild AD, 25% moderate AD, and about 17% severe AD. Children with AD had statistically significantly higher miR-155 expression levels in comparison to the control children, (p < 0.001). Children with severe AD had statistically significantly higher miR-155 expression levels compared to mild AD children (p=0.001). The receiver operating characteristic curve analysis for miR-155 demonstrated that miR-155 can differentiate between children with mild AD and those with moderate-to-severe AD, with an area under the curve of 0.879, and an excellent discrimination power. A statistically strong significant positive correlation existed between miR-155 levels and SCORAD severity index (rs= 0.666, p < 0.001). In conclusion, MiR-155 could be considered as a non-invasive biomarker of AD severity in children. It is a promising prognostic tool in the prediction of AD severity.

A comparative clinico-dermoscopic study of intralesional injection of combined digoxin and furosemide, Candida antigen, and vitamin D3 for multiple warts.

BACKGROUND: Immunostimulatory and antiproliferative therapies have been widely used for the treatment of multiple warts. Recently, anti-HPV activity of ionic contra viral therapy (ICVT) which is comprised of combined digoxin and furosemide has been demonstrated. AIM: To evaluate and compare the effectiveness and safety of intralesional injection of Candida antigen, vitamin D3, and combined digoxin and furosemide in the treatment of multiple warts. PATIENTS AND METHODS: Seventy-five patients with numerous warts were randomly assigned to one of three equal groups: Candida antigen, vitamin D3, or a combination of digoxin and furosemide. In the Candida antigen group, injections into the biggest wart were done. In the vitamin D3 and combined digoxin/furosemide groups, the agent was injected into each wart with a maximum of five injected warts. Injections were repeated every 2 weeks until clearance or for a total of five sessions. RESULTS: There was a statistically significant difference in the overall therapeutic response among the studied groups in favor of the intralesional Candida antigen group (60%), followed by the vitamin D3 group (48%) and the ionic contraviral therapy group (28%) (p = 0.02). However, the difference between both Candida antigen and vitamin D groups was not significant (p = 0.59). CONCLUSIONS: Intralesional Candida antigen immunotherapy and vitamin D3 antiproliferative therapy are significantly more effective than ICVT. LIMITATIONS: Short follow-up period and relatively small sample size.

Intralesional Versus Intramuscular Hepatitis B Virus Vaccine in the Treatment of Multiple Common Warts.

BACKGROUND: Hepatitis B virus (HBV) vaccination is associated with stimulation of humoral and cell-mediated immunity. Intralesional HBV vaccine has been recently used as an immunotherapy of common warts with relatively low success rate. AIM: To assess the efficacy and safety of intralesional versus intramuscular (IM) HBV vaccine in the treatment of multiple common warts. PATIENTS AND METHODS: The study included 60 patients with multiple common warts who were randomly assigned to 2 groups: intralesional HBV vaccine or IM HBV vaccine. In the intralesional HBV vaccine group, the vaccine was injected into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions. Intramuscular HBV vaccine group received 3 injections in the deltoid muscle at 0, 1, and 6 months. RESULTS: Complete wart clearance was reported in 7 patients (23.3%) of the intralesional HBV vaccine group and 15 patients (50%) of the IM HBV vaccine group. The difference was statistically significant in favor of the IM group ( p = .0479). Adverse effects were mild and insignificant in the 2 groups. CONCLUSION: HBV vaccine, particularly the IM form seems to be a promising, well-tolerated therapeutic option for the treatment of warts. LIMITATIONS: Short follow-up period and small sample size.

Serum immunoglobulin E and Interleukin-17 levels in patients with chronic plaque psoriasis: A case-control study.

BACKGROUND: Psoriasis is a skin disorder mainly mediated by T helper (Th)-1 and Th-17 cells. Recently, high serum immunoglobulin (Ig)-E levels were detected in psoriatic patients. The etiopathogenesis of IgE overproduction in psoriatic patients is still unknown, but IL-17 has been suggested to be responsible for this abnormality. OBJECTIVE: To compare levels of IgE and IL-17 in the sera of patients with chronic plaque psoriasis (CPP) to healthy subjects. METHODS: This study included 40 patients with CPP and 40 age- and sex-matched healthy individuals. Serum IgE and IL-17 concentrations were measured using the enzyme-linked immunosorbent assay (ELISA) technique. RESULTS: Levels of IgE and IL-17 were significantly higher in the sera of psoriatic patients than in controls (p = 0.001 and 0.024, respectively). Psoriatic patients with abnormally high serum IgE levels had higher serum IL-17 levels than those with normal serum IgE levels, but the difference was statistically insignificant (p = 0.080). Furthermore, no significant correlation was found between serum IgE and IL-17 concentrations in psoriatic patients (p = 0.385). CONCLUSIONS: It is possible that IgE and IL-17 interact in psoriasis pathogenesis; however, this was not evident in the current study, possibly due to the small sample size. Therefore, other potential causes of elevated IgE levels in psoriatic patients should be investigated. Moreover, the interaction between IgE and IL-17 should be investigated in patients with other clinical variants of psoriasis.

Voriconazole is superior to combined itraconazole/isotretinoin therapy and itraconazole monotherapy in recalcitrant dermatophytosis.

BACKGROUND: There has been an emergence of recalcitrant, recurrent, and difficult-to-treat tinea. Monotherapy with oral antifungals leads to partial clearance or high recurrence of lesions. Isotretinoin is a good adjuvant to systemic antifungals in chronic dermatophytosis. Voriconazole could be a future alternative due to its efficacy against dermatophytes and little resistance. OBJECTIVE: To evaluate the efficacy and safety of oral itraconazole, combined itraconazole/isotretinoin therapy, and voriconazole for recalcitrant tinea. PATIENTS AND METHODS: This study included 90 patients with chronic, recurrent and/or recalcitrant tinea. They were equally divided into three groups: itraconazole monotherapy, combined itraconazole/isotretinoin therapy, and voriconazole monotherapy. All patients received treatments for 6 weeks. The clinical response was classified as either a complete or incomplete clinical cure. Potassium hydroxide microscopy and culture were performed to identify mycological cure. Patients with complete cure were followed up for another 6 months to detect any recurrence. RESULTS: Complete clinical cure was observed in 53.3% of the itraconazole group, 70% of the itraconazole/isotretinoin group, and 83.3% of the voriconazole group. Mycological cure was detected in 56.7% of the itraconazole group, 83.3% of the itraconazole/isotretinoin group, and 86.7% of the voriconazole group. There was a statistically significant difference between the three groups in favour of voriconazole, then the combined group. No significant adverse effects were observed. The recurrence rate was significantly lower in the voriconazole group compared with the other two groups. CONCLUSIONS: Voriconazole could be a future alternative for the treatment of recalcitrant dermatophytosis.

Triple Intralesional Antigen Immunotherapy versus Monoantigen in the Treatment of Multiple Recalcitrant Warts.

INTRODUCTION: Warts can be resistant to treatment or recur despite the use of various destructive and immunotherapeutic modalities. Combination immunotherapy might contribute to better response rates. The aim of this study was to assess the effectiveness and safety of a triple intralesional immunotherapy combination composed of purified protein derivative (PPD), Candida antigen, and measles-mumps-rubella vaccine (MMR), versus each agent alone, in the management of multiple recalcitrant warts. METHODS: In total, 160 patients with numerous resistant extragenital warts were included in the research. They were randomly assigned to one of four groups (each with 40 patients): PPD, Candida antigen, and MMR, or combination of the three antigens. Injections into the biggest wart were repeated every 2 weeks until clearance or for a total of five sessions. RESULTS: Complete wart clearance was reported in 31 patients (77.5%) who received triple-antigen immunotherapy, 23 patients (57.5%) who received intralesional PPD, 29 patients (72.5%) injected with Candida antigen, and 25 patients (62.5%) who received MMR. The combined therapy was found to be superior to the other therapies and had the lowest recurrence rate, but the difference was not statistically significant. CONCLUSIONS: Triple intralesional antigen immunotherapy is as safe as, and more effective than, monoantigen immunotherapy, and can be added to the armamentarium against recalcitrant human papilloma virus (HPV) infections.

Intralesional immunotherapy for multiple recalcitrant plantar warts: Candida antigen is superior to intralesional purified protein derivative.

Treatment of recalcitrant plantar warts represent a highly challenging issue for both patients and physicians. Candida antigen and purified protein derivative (PPD) have shown promising efficacy in the treatment of warts, however no previous studies have compared both antigens for recalcitrant plantar warts. To assess the efficacy and safety of intralesional Candida antigen versus intralesional PPD in the management of recalcitrant plantar warts. The study included 120 adult patients with multiple recalcitrant plantar warts. They were randomly assigned to one of three groups; Candida antigen, PPD, or normal saline. Injections into the largest wart were repeated every 2 weeks until clearance or for a maximum of five sessions. Complete wart clearance was reported in 33 patients (82.5%) of the Candida antigen group, in 22 patients (55.6%) of the PPD group, and in one patient (5%) of the control saline group. A statistically significant difference was found between the studied groups in favor of Candida antigen. Adverse effects were mild and insignificant in the three groups. Intralesional antigen immunotherapy by Candida antigen or PPD is a promising, safe, and cost-effective therapeutic option for multiple recalcitrant plantar warts, with statistically significant superiority of Candida antigen.
