Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: 1. Written informed consent. 2. >=18 years old. 3. Patients that are recently diagnosed with pemphigoid (bullous or nonbullous) or pemphigoid patients that were in complete remission without therapy and experience a relapse can be included. [The following diagnostic criteria are used for cutaneous pemphigoid: a positive DIF with linear IgG and/or C3c along the BMZ, and/or positive IIF on SSS or monkey esophagus, in combination with compatible clinical presentation, histopathological findings, or other immunoserological tests.] If the criteria are fulfilled, patients will be categorized into the nonbullous phenotype (no history and no current blistering on the skin) or the bullous phenotype. 4. Active disease with skin lesions.

Exclusion criteria

Exclusion criteria: 1. The use of systemic immunosuppressive medication, such as prednisolone (>0.3mg/kg/day), methotrexate, azathioprine or dapsone (see guideline Feliciani et al)5 within the last 4 weeks before the sample collection. Prednisolone in a dosage

Design outcomes

Primary

MeasureTime frame
1. Differences in gene expression levels in the skin of healthy persons, nonbullous pemphigoid patients and bullous pemphigoid patients by RNA sequencing. 2. Differences in the number of activated and apoptotic eosinophils and IL-31 expression in the skin and blood between healthy controls, nonbullous pemphigoid and bullous pemphigoid by immunofluorescence staining and flowcytometry .
