chloroquine and Acute Rheumatic Fever

chloroquine has been researched along with Acute Rheumatic Fever in 25 studies

Chloroquine: The prototypical antimalarial agent with a mechanism that is not well understood. It has also been used to treat rheumatoid arthritis, systemic lupus erythematosus, and in the systemic therapy of amebic liver abscesses.
chloroquine : An aminoquinoline that is quinoline which is substituted at position 4 by a [5-(diethylamino)pentan-2-yl]amino group at at position 7 by chlorine. It is used for the treatment of malaria, hepatic amoebiasis, lupus erythematosus, light-sensitive skin eruptions, and rheumatoid arthritis.

Trial Overview

Trial Outcomes

Adjusted Mean Change From Baseline in Log Transformed C - Reactive Protein (CRP) at Day 84

Blood draw for CRP, an acute phase reactant used to identify the presence of nonspecific inflammation. Change=Day 84 value minus Baseline value. Normal serum CRP reference range in this study is 0-4 mg/L (log transformed: -4.2 to 1.4). Participants with measurements for designated time points were included in analysis. An increased CRP level indicates the presence of inflammation. Reduced CRP levels could mean a decrease in inflammation. (NCT00302952)
Timeframe: Baseline (Day 0), Day 84 (Wk 12)

Adjusted Mean Change From Baseline in Serum Anti-cyclic Citrullinated Peptide (Anti-CCP) by ELISA (ELISA: Enzyme-linked Immunosorbent Assay)

Anti-CCP antibodies are autoantibodies frequently detected in the serum of individuals with rheumatoid arthritis. In this study, a positive value for anti-CCP was 8 IU/mL or greater; a negative value for anti-CCP was <8 IU/mL. Change= subtraction of Day 0 from Day 84 anti-CCP value. In general, high levels of the antibody indicate an aggressive rheumatoid arthritis and a higher risk of joint damage. Participants with measurements for designated time points included in analysis. (NCT00302952)
Timeframe: Baseline ( Day 0), Day 84 (Wk 12)

Adjusted Mean Change From Baseline in Serum IgM Rheumatoid Factor by ELISA (ELISA: Enzyme-linked Immunosorbent Assay)

Rheumatoid factor (RF) is an antibody often present in the blood of a person with rheumatoid arthritis. In this study, a positive value for RF was 0.5 IU/mL or greater; a negative value for RF was <0.5 IU/mL. Change= Day 84 value minus Baseline value. In general, presence of the antibody indicates aggressive rheumatoid arthritis and higher risk of joint damage. Participants with measurements for designated time points included in analysis. (NCT00302952)
Timeframe: Baseline (Day 0), Day 84 (Wk 12)

Adjusted Mean Change From Baseline in the Disease Activity Score Using C-reactive Protein (DAS28-CRP) on Day 84

The DAS28-CRP score is on a scale of 0 to 10 and indicates current activity of rheumatoid arthritis (>5.1=high disease activity; 3.2-<=5.1=moderate disease activity; <=3.2=low disease activity; <2.6=remission). The score uses a combination of four variables: 1) the number of tender joints (of the 28 that are measured); 2) the number of swollen joints (of the 28 that are measured); 3) serum C-reactive protein (CRP) lab value in mg/L , and 4) Patient Global Assessment of Disease Activity. Using a formula, the physician determines the score. Participants with measurements for designated time points included in analysis. (NCT00302952)
Timeframe: Baseline (Day 0) to Day 84 (Wk 12)

Change From Baseline in CPK at Day 84

Blood samples were taken from participants at Baseline and Day 84. Participants with measurements for designated time points included in analysis. Change=Day 84 value minus Baseline value. A positive difference reflects an increased laboratory parameter value over time; a negative difference reflects a decreased laboratory parameter value over time. Normal laboratory values depend on a subject age, gender, and the specific laboratory methods that were used to determine the lab values.
