简要总结
Based on ADVOR trial, the potential of adding acetazolamide in increasing the success of decongestion, the amount of natriuresis and diuresis. However, the use of intravenous acetazolamide may not be possible in Indonesia, where the intravenous formulation is not available. This clinical research study is being conducted in single hospitals in Indonesia. We aim to learn if Oral Acetazolamide in addition to Furosemide intravenous works to treat congestion in Acute Decompensated Heart Failure, besides evaluating the total urinary output, change of NT pro BNP level, and safety profile of oral Acetazolamide.
The hypothesis of this study is oral acetazolamide works well to achieve successful decongestion.
详细描述
This is a randomized, double blind study with 2 treatment groups. Participants diagnosed with ADHF who meet the inclusion criteria and no exclusion criteria are given an explanation regarding the research and additional therapy that will be given, then informed consent is requested. Participants will be randomized to one of the two treatment groups by chance. Patients randomized to the first group will receive intravenous furosemide and oral acetazolamide. Patients randomized to the other treatment group will receive a combination of iv furosemide and placebo. It is expected that the patients of the treatment group with the combination therapy will have a faster reduction of their fluid overload. In consequence the treatment duration and total dose of diuretics administered will be shorter.

- •Patients with a clinical diagnosis of acute decompensated heart failure with at least one clinical sign of volume overload with a congestion score ≥2 (ADVOR Score) (e.g. edema (score 2 or more), ascites confirmed by physical examination or ultrasonography or pleural effusion confirmed by chest x-ray or echocardiography).
- •Patients on routine oral loop diuretic therapy with a dose of ≥40 mg furosemide for ≥1 month
- •Plasma NT-proBNP levels that increase ≥300 pg/mL or the applicable cut-off according to the age range at the time of examination in the ER.
排除标准

- •Subjects in cardiogenic shock.
- •Estimated glomerular filtration rate <20 mL/min/1.73m² at the time of examination.
- •Use of renal replacement therapy or ultrafiltration at any time before the study was included.
- •Treatment with acetazolamide within 1 month before randomization.

研究组 & 干预措施
Group A (Oral Acetazolamide)
Participants who received intravenous furosemide plus acetazolamide 250 mg / 12 hours orally for up to 3 days.
干预措施: Oral Acetazolamide (Drug)
Group B (Placebo)
Participants who received intravenous furosemide plus Placebo / 12 hours orally for up to 3 days.
干预措施: Placebo (Drug)
结局指标
主要结局
Successful Decongestion
时间窗: within 3 days
Conditions without volume overload, no signs of excess volume within 3 days of treatment. Congestion was assessed using the volume assessment score (also called congestion score) from the ADVOR trial. The absence of fluid volume excess was defined as no more than mild edema, no residual pleural effusion, and no residual ascites. Total score ≤1 indicates that decongestion has been achieved, score \>1 is considered to indicate persistent fluid volume excess (decongestion not achieved).
次要结局
- NT pro BNP(within 3 days)
- Renal Function(From date of randomization until the date of first documented worsening renal function (increased of creatinine serum level >50% of baseline creatinine) or date of death from any cause, evaluation every 48 hours or whichever came first, up to 90 days)
- Urinary Output(From date of randomization until participants discharge from hospital up to 7 days post discharge.)
- Length of Stay(From date of randomization until the date of first documented progression and discharge from hospital or date of death from any cause, whichever came first, assessed up to 30 days.)
