About this study

This study will compare the pattern of Th17 immune response in active and inactive pemphigus subjects. Skin and serum samples will be taken at the moment of enrollment.

Read the detailed description

Pemphigus is an autoimmune disease characterized by production of autoantibodies against desmogleins 1 and 3, which are part of the epidermis desmosomes. The first line of treatment are corticosteroids with or without the use of adjuvants (e.g. azathioprine, mycophenolate or rituximab). T lymphocytes are responsible for the initiation and maturation of the humoral response and the B cell activation required for the production of autoantibodies. In the last decade, the Th17 immune response has been implicated in the pathogenesis of pemphigus. Recently, the existence of tertiary lymphoid organ-like structures within the skin lesions was suggested. This structures contain T lymphocytes, B lymphocytes and plasma cells; these cells interact and create a local microenvironment for the production of autoantibodies. Most of the T cells in this structures are T helper CD4+ and express IL-21, and half of them produce IL-17.

In this study the investigators aim to evaluate comparatively the Th17 and T regulatory immune response in the lesional skin and serum of active and inactive pemphigus subjects that are treated with corticosteroids with or without adjuvants and a third group of healthy subjects. The investigators will study skin and serum due to the difference of lymphocytes and cytokines in both tissues. The primary hypothesis is: active pemphigus vulgaris subjects will have different levels of TH17 response in comparison to inactive patients.

The investigators will use descriptive statistics, association and correlation test of hypothesis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of Th17 cytokines in skin of pemphigus vulgaris subjects

    The level of IL-17a, IL-21, IL-22, and IL-23 mRNA from skin biopsies at the time of enrollment and when the subject reaches 75% of PDAI improvement or after a year of follow-up (termination visit). The percentage of change in these two determinations will be calculated.

What does the primary outcome measure?

Level of Th17 cytokines in skin of pemphigus vulgaris subjects (time frame: Enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04096222, which also lists 70 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
