Prevalence of Disease
The prevalence of Vitiligo has been reported as 0.5%
to 1% in the world with the highest prevalence in India at about 8.8%, mostly
in the states of Rajasthan and Gujarat.
Need of Study
Vitiligo is considered as an autoimmune disease
which causes depigmentation of the skin. The quality of the life of the
patients is significantly affected because of its disfiguring nature. When
considering the prevalence of Vitiligo, the highest number of patients are
found in the states of Rajasthan and Gujarat with the prevalence varying in the
range of 0.46% to 8.8% and it impacts the quality of life of the patients.
Therefore there is a need to explore more treatment procedures to make aware of
the patients and their families to manage their condition effectively and
improve their quality of life.
PUVA therapy has been used as the main treatment for
Vitiligo since 2000 BC with the use of plant-origin synthetic compounds. But it
has been associated with side effects due to Psoralen intake and, relapses, and
recurrences of the condition. Furthermore, no clinical studies have been conducted
to assess the effect of UVA along with the use of Ayurvedic formulation. Hence hereby
it is the need of hour to conduct such clinical trials to import better results
in the management of Shvitra (Vitiligo).
Research Gap
There is no data found on the studies that have been
conducted to assess the efficacy of UVA phototherapy along with Ayurveda
classical medicines. Therefore to fill this gap, a comparative clinical trial
to assess the efficacy of Aragvadhadya Taila and Shashilekha Vati
with and without Ultra Violet Rays Band A on VASI Score in Shvitra will
be conducted to find out the relative efficacy and safety.
Rationale for selection of interventions/
justification for selection of trial drugs
In this study, Aragvadhadya Taila and Shashilekha
Vati will be used. Aragvadhadya Taila is an
external application mentioned in Chakradatta and Shashilekha Vati
is an internal medicinal preparation mentioned in Yogaratnakar. These
two classical formulations have ingredients that are found to be effective in
the management of Shvitra and cost-effective. Therefore, this study will
be carried out to assess the efficacy of Ultra Violet Rays Band A along with Aragvadhadya
Taila and Shashilekha Vati on VASI score in Shvitra.
Research Question
Is there any difference in efficacy of Aragvadhadya
Taila and Shashilekha Vati when used alone versus Aragvadhadya
Taila and Shashilekha Vati when used with UVA in the management of Shvitra?
Hypothesis
Null hypothesis (H0):
There is no any difference in efficacy of Aragvadhadya
Taila and Shashilekha Vati versus Aragvadhadya Taila and Shashilekha
Vati when used with UVA in the management of Shvitra.
Alternate hypothesis (H1):
There is a difference in efficacy of Aragvadhadya
Taila and Shashilekha Vati versus Aragvadhadya Taila and Shashilekha
Vati when used with UVA in the management of Shvitra.
Aim
To assess the
efficacy of Aragvadhadya Taila and Shashilekha Vati with and
without UVA on VASI Score in Shvitra in and around National Institute of
Ayurveda, Jaipur.

Randomized Comparative Clinical Trial
·
Prospective
Number of groups
2 groups
Group A - 20 Subjects
Group B - 20 Subjects
Site of Study: National
Institute of Ayurveda Hospital, Jaipur.
Study
Setting: OPD and
IPD of National Institute of Ayurveda Hospital, Jaipur. 40 subjects will be
selected according to inclusion criteria from those who are visiting the OPD
& IPD of National Institute of Ayurveda. Subjects will be categorized into
two groups, namely Group A and Group B each group containing 20 subjects.
Informed written consent will be taken from the subjects and a sensitivity test
for Aragvadhadya Taila & Phototherapy will be done prior to
commencement of the trial.
Sensitivity Test for Aragvadhadya Taila &
Phototherapy
Consent of the patient will be taken.
A small amount of the Aragvadhadya Taila will
be applied on the anterior surface of the elbow (inner elbow/Cubital fossa) and
after 10 minutes this area will be exposed to phototherapy for 5 minutes. The patient
will be asked to stay in the premises for 30 minutes for observation and if there
is no reaction, the patient will be informed to observe the marked area for 24
hours and report for any allergic reaction.
Participants/ population of Interest: Patients
who are visiting the OPD and IPD of National Institute of Ayurveda
Hospital, Jaipur.

Sample
Size:
Where n= Sample size, z = z score,
p = estimated prevalence, d = margin of error
Although, the calculated sample
size for the present study is approximately 113, but due to time and budget
constraints the present study will be conducted on 40 subjects and selected
subjects will be divided in to 2 groups as Group A and Group B each group
containing 20 subjects.
Screening criteria:
Subjects will be selected by
clinical examination and by examining the skin using a Wood’s lamp.
Diagnostic criteria:
The
condition of the subjects will be diagnosed by reviewing their medical history
and examining the skin using Wood’s lamp.
The
condition will be assessed based on the number, size, and the colour of the
patches and the VASI (Vitiligo Area Scoring Index) Score.
Withdrawal Criteria:
i.
Subjects who develop any adverse drug
reaction during the process of the treatment.
ii.
Subjects who are not willing to continue
the treatment process.

In the occasion of any adverse drug
reaction (ADR) or Adverse Drug Event (ADE).

Vitiligo Area Scoring Index (VASI)[3]
The
Vitiligo Area Scoring Index (VASI) is determined by the product of the area of
vitiligo in each body region in hand units and the extent of depigmentation
within each hand unit.
One
hand unit, approximately equivalent to 1% of the total body surface area.
