Evaluation of the Effect of Sulphur Mineral, Thermal Water on Skin Microbiome in Plaque Psoriasis, a Pilot Study
Study Overview
Detailed Description
Psoriasis is a chronic inflammatory skin disease. It is associated with several important medical conditions, including psoriatic arthritis, and cardiometabolic syndrome. Its most common form, chronic plaque.The aim of this study is to evaluate how Lake Hévíz sulphur thermal mineral water therapy influences the composition of microbial communities that colonizes skin in patients with psoriasis, and the extent and severity of skin symptoms of psoriasis.
The planned participants number is 16 outpatients between 18 and 70 years of age with mild to moderate psoriasis. The balneotherapy takes place in Lake Hévíz, five times a week for three weeks.
The skin microbiome is collected from two different place by swabbing method from the patient. One sample is collected from the normal skin, which is not affected by psoriasis (crook of the arm), the second sample is collected from psoriatic plaque of the elbow. The samples is processed for a sequence-based microbiome analysis.
The skin microbiome is evaluated by the analysis of the sample metagenome compositions, and the activity of psoriasis is evaluated on The Psoriasis Area and Severity Index (PASI), is taken at week 0., at week 3.

The skin microbiome was collected by swabbing method from the crook of the arm (normal skin) and the nearest plaque's surface. Balneotherapy in Lake Hévíz, 36℃ sulphur, carbonate, calcium, magnesium, hydrogen carbonate and very light radon-content thermal-mineral water 15 times in 3 weeks 30-minute therapy sessions. The total mineral substance of the water is 754 mg/l. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
1. Alpha diversity
Time Frame: baseline to week 3
|
Determination of microbiom in samples (bacterial DNA are isolated from the skin to determine the microbial composition) Number of species with Shannon-, Simpson and Chao1 indexes
|
baseline to week 3
|
|
2. Change in microbiota diversity before and after balneotherapy treatment
Time Frame: baseline to week 3
|
Change in alpha diversity before and after treatment:to compare normal samples before and after treatment, to compare psoriasis samples before and after treatment and the comparison of normal and psoriasis samples before treatment.Differences in genus abundances to determine with the core function of the microbiome R package (Lahti et al., 2019), with detection 100 and prevalence 0.1.
|
baseline to week 3
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
1. Beta diversity
Time Frame: baseline to week 3
|
Inter-sample genus composition differences by the Bray-Curtis beta-diversity metric
|
baseline to week 3
|
|
2. The Psoriasis Area and Severity Index (PASI) allows evaluating the extent and severity of skin symptoms of psoriasis.
Time Frame: baseline to week 3
|
Percentage of Participants With a 50% Reduction From Baseline Psoriasis Area and Severity Index (PASI 50) at Week 3. The PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination.
The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis.
PASI 50 is defined as at least a 50% reduction in PASI score compared with the Baseline PASI score.
