- Brief Summary
Psoriasis affects around 4% of world population. The disease could be disabling and disfiguring dermatologic condition. World Health Organization (WHO) has recently drawn the attention to the inadequate treatment options psoriasis patients suffer from among other problems. Furthermore, the available treatment options have many side effects. A lot of the effective treatment options are either expensive or not appropriate for hepatic patients who represent a large subset of Egyptian psoriatic patients. This highlights the need for inexpensive and safe alternative. The effectiveness of Turmeric in psoriasis treatment have been addressed in few reports. Having an immune modulatory effect especially as anti NFκB it is expected to be effective therapy with minimal side effect. Up to the investigator's knowledge this is the first study addressing the efficacy of combined turmeric and olive oil based topical therapy in psoriasis treatment
- Detailed Description
Psoriasis is a prevalent skin disorder. It affects around 4% of world's population. It can be disfiguring and disabling in severe cases. There is dysregulated immune response in psoriatic patients to unknown injurious agents with upregulation of Th1/Th17 pathways which is mediated via Nuclear Factor kappa B (NFκB). NFκB is a key player in psoriasis development; its activation and nuclear translocation is present in every step of the way of psoriasis starting from keratinocyte release of cytokines -in response to stress- to the maturation and activation of dendritic cells, to the continuous loop of T cell activation.
Turmeric extract has anti-inflammatory, anti-oxidant, anti-microbial and anti-carcinogenic effects. It has inhibitory effects on NF-κB and various cytokines production.
In this clinical trial 5 groups of patients with mild to moderate psoriasis are recruited; group (A) Receiving the Turmeric extract based ointment only. Group (B) receiving Turmeric extract + olive oil based treatment. Group (C) will serve as negative control receiving only petrolatum base. Group (D) will receive NB UVB serving as positive control. Group (E) will receive established topical treatment serving as positive control.
Each patient will be assessed on weekly bases clinically for the disease severity using PASI score and via dermatoscope. Histopathological evaluation (H\& E along with NFkB expression analysis) will be done at 4 points of time baseline, 4 weeks, 8 weeks, 12 weeks through the study.

Group Intervention Description Turmeric Extract group Turmeric Extract 10 psoriasis patients receiving turmeric based ointment levigated in glycerin twice daily and assessed for response and side effects weekly for 12 weeks Turmeric extract + olive oil group Turmeric Extract in Olive oil 10 psoriasis patients receiving turmeric extract levigated in olive oil instead of glycerin. The ointment will be applied twice daily for 12 weeks \& will be assessed weekly NBUVB group NB-UVB 10 Psoriasis patients will receive two sessions of NBUVB weekly for 12 weeks and will be assessed weekly clinically and with dermoscope. Established ttt group calcipotriol/ Betamethasone 10 Psoriasis patients will receive topical betamethasone dipropionate or calcipotriol cream twice daily for 12 weeks and will be assessed on weekly basis clinically and by dermoscope Petrolatum group Petrolatum 10 Psoriasis patients will receive the base of the therapeutic ointment which is the petrolatum. Patients will apply it twice daily and will be assessed weekly clinically and dermoscopically for 12 weeks
- Primary Outcome Measures
Name Time Method Change in NFϰB expression Baseline and every 4 weeks till the end of 12 weeks. The NFϰB expression will be identified by the percentage of positive nuclear stained epidermal cells in slide at base line and every 4 weeks till the end of study which is 12 week
Change in psoriasis severity Weekly basis for 12 weeks Response to therapy will be assessed using dermatoscope with software mediated image analysis.
Change in Psoriasis Area & Severity Index (PASI) 12 weeks Response to therapy is assessed via measurement of (PASI) every week for 12 w. The range of PASI score is from 0 (no disease) - 72 (sever disease). In PASI, the body is divided into four sections (head; arms; trunk; legs). Each of the sections is scored by itself, and then the four scores are combined into the final PASI. For each section, area of involved skin is given a grade from 0 to 6: 0= 0% of involved area, 1 = \< 10% involved, 2=10-29% involved, 3 =30-49% involved area, 4 = 50-69% involved, 5 =70-89% involved, 6 = 90-100%involved. Within each section, the severity is estimated in three clinical parameters: erythema (redness), induration (thickness) and desquamation (scaling). Severity parameters are measured on a scale of 0 to 4, from none to maximum. The sum of three severity parameters is calculated for each section of body, multiplied by the area score for that section and multiplied by weight of respective section (0.1 for head, 0.2 for arms, 0.3 for body and 0.4 for legs).
Change on pathology level Baseline and every 4 weeks for the period of the study (12 w) Histopathologic evaluation of hematoxylin and eosin stained slides from psoriatic lesions before and after treatment or placebo. The slides will be given a score based on the presence or absence of each of the following: Hyperkeratosis (0.5), One mitosis/3 rete ridges (0·5), Acanthosis (1),Dermis lymphocytic infiltrate; Mild (0·5) Moderate (1) Marked (2·0) Parakeratosis (1),Papillary congestion (0.5),Lack of granular layer (1), Munro abscesses (2), Thinning above the papillae (0.5), Length of rete ridges (0.5), Clubbing of rete ridges (0·5). The sum score of each patient's slide will be recorded at baseline \& every 4 week
