Trial summary

Bullous pemphigoid (BP) is the most common autoimmune bullous dermatosis. It mainly affects the elderly, and its cutaneous manifestations are extremely varied. Since the publication of the first case of PB associated with sulfasalazine in 1970, several drugs have been reported for their potential link with the… Read more about this study

Study population: Patients from three university departments of Dermatology with type 2 diabetes and a diagnosis of PB diagnosed for the first time between January 1, 2014 and July 31, 2016

Who may be able to join

  • Case: Patients from three university departments of Dermatology (Marseille North, Marseille La Timone, Bern) with type 2 diabetes, and a diagnosis of PB diagnosed for the first time between January 1, 2014 and July 31, 2016.

  • Witnesses: Patients from two university departments of Endocrinology (Marseille La Conception and Bern) with type 2 diabetes, and matched 1: 2 to cases for sex and age.

Who cannot join

  • Case: Patients with another bullous dermatosis, not meeting the inclusion criteria. Patients biopsied before consultation in University Hospital, or patients seen in private dermatology practices.

About this study

Official title: Dipeptidyl Peptidase-IV Inhibitors, Risk Factor for Development of Bullous Pemphigoid? : Multicenter Retrospective Study in France and Switzerland

Bullous pemphigoid (BP) is the most common autoimmune bullous dermatosis. It mainly affects the elderly, and its cutaneous manifestations are extremely varied. Since the publication of the first case of PB associated with sulfasalazine in 1970, several drugs have been reported for their potential link with the development of PB. Recently, cases of PB associated with dipeptidyl peptidase-IV (DPP4) inhibitors, also known as gliptins, have been reported. DPP4 inhibitors are oral antidiabetic agents prescribed to patients with type 2 diabetes, as monotherapy, in combination with other oral antidiabetic agents or with insulin.

In recent years, an increasing number of cases have been published, describing the potential role of gliptins in PB induction. All these clinical cases and pharmacovigilance analyzes tend to show an increased risk of developing BP in case of gliptin exposure.

The main objective is to evaluate the risk of developing a PB under DPP4 inhibitor treatment, comparing cases of diabetic patients with BP, to matched diabetic controls for sex and age, from French departments. Endocrinology in a retrospective study from 1 January 2014 to 31 July 2016.

The study will be conducted using databases of clinical and histological records. The investigators will perform a retrospective 1: 2 case-control study comparing cases with type 2 diabetes and BP to matched diabetic controls for sex and age, randomly drawn from French endocrinology departments (Marseille La Conception ) and Switzerland (Bern), between January 1, 2014 and July 31, 2016. the investigators will compare gliptin exposure in the case-control group versus the control group, adjusting for potential confounding bias using models. logistic regression.

Read the detailed description

Bullous pemphigoid (BP) is the most common autoimmune bullous dermatosis. It mainly affects the elderly, and its cutaneous manifestations are extremely varied. Since the publication of the first case of PB associated with sulfasalazine in 1970, several drugs (spironolactone, furosemide, chloroquine, beta-blockers and various antibiotics) have been reported for their potential link with the development of PB. Recently, cases of PB associated with dipeptidyl peptidase-IV (DPP4) inhibitors, also known as gliptins, have been reported. DPP4 inhibitors are oral antidiabetic agents prescribed to patients with type 2 diabetes, as monotherapy, in combination with other oral antidiabetic agents or with insulin.

Problem raised:

In recent years, an increasing number of cases have been published, describing the potential role of gliptins in PB induction. All these clinical cases and pharmacovigilance analyzes tend to show an increased risk of developing BP in case of gliptin exposure, but this hypothesis has not yet been confirmed by a quality controlled study.

Goal:

The main objective is to evaluate the risk of developing a PB under DPP4 inhibitor treatment, comparing cases of diabetic patients with BP, to matched diabetic controls for sex and age, from French departments. Endocrinology (Marseille La Conception) and Dermatologie (Marseille North, Marseille La Timone) and Swiss (Bern), in a retrospective study from 1 January 2014 to 31 July 2016.

Material and methods:

The study will be conducted in three university departments of Dermatology (Marseille North, Marseille La Timone, Bern), using databases of clinical and histological records. The investigators will perform a retrospective 1: 2 case-control study comparing cases with type 2 diabetes and BP to matched diabetic controls for sex and age, randomly drawn from French endocrinology departments (Marseille La Conception ) and Switzerland (Bern), between January 1, 2014 and July 31, 2016. The investigators will compare gliptin exposure in the case-control group versus the control group, adjusting for potential confounding bias using models. logistic regression.

Criteria for inclusion:

  • Case: Patients from three university departments of Dermatology (Marseille North, Marseille La Timone, Bern) with type 2 diabetes, and a diagnosis of PB diagnosed for the first time between January 1, 2014 and July 31, 2016. The diagnosis of PB is based on compatible clinical presentation, compatible histology, positive direct immunofluorescence (IFD), and in some cases positive indirect immunofluorescence (IFI) and / or the presence of autoantibodies (BP180 and / or BP230) by ELISA.
  • Witnesses: Patients from two university departments of Endocrinology (Marseille La Conception and Bern) with type 2 diabetes, and matched 1: 2 to cases for sex and age.

Exclusion criteria:

  • Case: Patients with another bullous dermatosis, not meeting the inclusion criteria. Patients biopsied before consultation in University Hospital, or patients seen in private dermatology practices.
  • Witnesses: Patients suffering at the time of inclusion of a chronic dermatosis, in particular of a bullous dermatosis.

Questions about this trial

What is this clinical trial studying?

An observational study of Bullous Pemphigoid, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Michael Joseph BENZAQUEN (+33 491964962, MICHAEL.BENZAQUEN@ap-hm.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

numbers of patients exposed to gliptin (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2018.
