Use of gelsolin to diagnose and treat inflammatory diseases
The invention relates to the use of gelsolin to treat inflammatory diseases (e.g., rheumatoid arthritis) and to the use of gelsolin to diagnose, monitor, and evaluate therapies of inflammatory diseases (e.g., rheumatoid arthritis).
1. A method for treating a subject having an inflammatory disease comprising:
administering to a subject in need of such a treatment an effective amount of plasma gelsolin to treat the subject, wherein the inflammatory disease is rheumatoid arthritis or inflammatory bowel disease.
2. The method of claim 1 , wherein the subject is otherwise free of indications calling for treatment with gelsolin.
3. The method of claim 1 , wherein the inflammatory disease is rheumatoid arthritis.
4. The method of claim 1 , wherein the inflammatory disease is inflammatory bowel disease.
5. A method for treating a subject having an inflammatory disease comprising:
administering to a subject in need of such a treatment an effective amount of plasma gelsolin to raise the level of gelsolin in the subject above a predetermined value, wherein the inflammatory disease is rheumatoid arthritis or inflammatory bowel disease.
6. The method of claim 5 , wherein the subject is otherwise free of indications calling for treatment with gelsolin.
7. The method of claim 5 , wherein the predetermined level of gelsolin is a level of gelsolin in an apparently healthy control population.
8. The method of claim 5 , wherein the predetermined value of gelsolin is about 250 mg/L of plasma or higher.
9. The method of claim 5 , wherein the inflammatory disease is rheumatoid arthritis.
10. The method of claim 5 , wherein the inflammatory disease is inflammatory bowel disease.
11. A method for treating a subject to reduce the risk of an inflammatory disease comprising:
(i) selecting a subject who has a below-normal level of gelsolin and
(ii) administering to the subject plasma gelsolin and/or a second agent in an effective amount to reduce the risk of the subject developing the inflammatory disease, wherein the inflammatory disease is rheumatoid arthritis or inflammatory bowel disease.
12. The method of claim 11 , wherein the subject is otherwise free of indications calling for treatment with gelsolin.
13. The method of claim 11 , wherein the inflammatory disease is rheumatoid arthritis.
14. The method of claim 11 , wherein the inflammatory disease is inflammatory bowel disease.
15. A method for treating a subject to reduce the risk of an inflammatory disease comprising:
(i) selecting a subject who has a below-normal level of gelsolin and
(ii) administering to the subject plasma gelsolin and/or a second agent in an effective amount to raise the level of gelsolin in the subject above a predetermined value, wherein the inflammatory disease is rheumatoid arthritis or inflammatory bowel disease.
16. The method of claim 15 , wherein the subject is otherwise free of indications calling for treatment with gelsolin and/or is apparently healthy.
17. The method of claim 15 , wherein the inflammatory disease is rheumatoid arthritis.
18. The method of claim 15 , wherein the inflammatory disease is inflammatory bowel disease.
