Anti-C1s, Anti-HMGB1 and Anti-C1q Autoantibodies in Systemic Lupus Erythematosus (DYSALARM-322)
This research is investigating certain natural substances found in the blood, called autoantibodies (anti-C1s, anti-HMGB1, and anti-C1q), in people with active lupus. Lupus is a long-term condition where the body's immune system mistakenly attacks its own healthy tissues. We're trying to understand how these specific autoantibodies might play a role in causing lupus symptoms and the damage seen in the body. The study will look at blood samples from 30 lupus patients to find out exactly what these autoantibodies target and how they affect important body functions. By learning more about these substances, we hope to improve our understanding of lupus, which could eventually lead to better ways to manage the condition.

על מה המחקר הזה?
Lupus (Systemic Lupus Erythematosus or SLE) is a condition where your body's defence system, called the immune system, mistakenly attacks your own healthy tissues. This can lead to widespread inflammation and damage in many parts of the body. In people with lupus, the body often produces special proteins called 'autoantibodies' that target its own components. This study is focusing on three specific types of these autoantibodies: anti-C1s, anti-HMGB1, and anti-C1q.
Scientists believe that some proteins involved in how our immune system works, specifically C1q and C1s, and another protein called HMGB1, might not be working correctly in people with lupus. These autoantibodies might be interfering with how these proteins usually behave. We don't fully understand yet what these autoantibodies do, especially outside of their well-known roles in the body's natural defence system. This study aims to shed more light on this mystery.
This small study will involve 30 patients who have active lupus. Researchers will take blood samples, which are already part of regular patient care. They will then look closely at these samples to see what specific parts of the body these autoantibodies are targeting. They will also explore how these autoantibodies affect the way certain parts of your immune system and other body processes work. By understanding this better, we hope to gain valuable insights into what causes lupus symptoms.
נקודות עיקריות
- A research study looking at specific immune proteins in lupus patients.
- Aims to understand what causes lupus symptoms.
- Uses existing blood samples from routine care.
- Could help develop better lupus treatments in the future.
- Involves 30 patients with active lupus.
מי עשוי להיות זכאי?
To be considered for this study, you need to be at least 18 years old and weigh 40 kilograms (about 6 stone 4 pounds) or more. You also need to have valid health insurance. Most importantly, you must have a confirmed diagnosis of lupus based on specific medical criteria, and your lupus should be active, particularly affecting your joints and/or kidneys, as measured by a specific lupus activity score (SLEDAI score over 5).
There are also some reasons why you wouldn't be able to join the study. These include if you are under 18, pregnant, or breastfeeding. Also, if you are undergoing dialysis or plasma exchange treatments, you wouldn't be able to participate. This also applies to anyone who is legally protected, such as those under a guardianship, in prison, or compulsorily hospitalised.
האם מחקר זה יכול להתאים לך?
ענה על השאלות המהירות הללו כדי לבדוק אם אתה עשוי להיות זכאי. זהו מדריך בלבד — צוות המחקר מקבל את ההחלטה הסופית.
- האם אתה בן 18 או יותר?
- Do you weigh at least 40 kilograms (about 6 stone 4 pounds)?
- Do you have a current diagnosis of lupus with active symptoms, especially affecting your joints or kidneys?
- האם את לא בהריון או מניקה?
- Are you NOT currently on dialysis or plasma exchange treatments?
מה כרוך בהשתתפות?
This is a pilot study, meaning it's a small initial investigation. It involves taking blood samples that are already part of your routine medical care for your lupus. You will not receive any new medication as part of this study. There is no specific duration mentioned for individual patient participation beyond the collection of routine blood samples. It focuses on laboratory analysis of these samples to understand the autoantibodies.

שאלות נפוצות
What is lupus?
Lupus is a long-term condition where your body's immune system mistakenly attacks its own healthy tissues and organs.
What are autoantibodies?
Autoantibodies are special proteins made by your immune system that, in conditions like lupus, wrongly target and attack your own body's cells or tissues.
Will I get new medication in this study?
No, this study does not involve giving new medication. It uses blood samples already taken during your routine medical care.
What does a 'pilot study' mean?
A pilot study is a small, initial research project designed to test an idea or method before conducting a larger, more detailed study.
How many people are in this study?
This study plans to include 30 patients who have active lupus.
