    Historical Control Studies
    مطالعه با کنترل گذشته نگر
    This is a randomized controlled clinical trial with parallel design. We apply balanced block randomization method for randomization. Randomization sequence will be give to a person out of the research team in order to perform concealment.
    این مطالعه یک کارآزمایی بالینی تصادفی و کنترل شده با طراحی موازی است. بیماران به ترتیب ورود به پژوهش و بر اساس روش Balanced Block Randomization در یکی از این دو گروه قرار می گیرند. گروه یک به عنوان گروه مداخله ( داروی NAC) و گروه دو به عنوان گروه کنترل (پلاسبو) در نظر گرفته می شوند. به منظور پنهان سازی فهرست توالی بیماران در اختیار فردی خارج از گروه تحقیق قرار داده می شود و با ورود هریک از بیماران به مطالعه، گروه مطالعه از وی سوال خواهد شد.
    NAC and placebo are made in the form of similar tablets by the pharmaceutical company. Only one person on the study team who is responsible for randomization takes the tables, puts them in similar packages and encodes as a sequence of numbers according to a list of Balanced Block Randomization. Upon arrival of the each eligible patient, the coded package will be provided with a label that includes the drug numerical code, patient name, and study code. Except for the above person, no body, including the treating physician, the person in charge of data collection and analysis, statistical analyzer, and the patient himself, are aware of the type of drug. Allocation concealment samples are done by the people of the center that they and patients do not have any information about the researcher's aim.
    داروی NAC و پلاسبو به صورت قرص های مشابه توسط شرکت دارویی ساخته شده و در اختیار یک فرد از تیم مطالعه قرار خواهد گرفت. این فرد دارو ها را در بسته بندی های مشابه قرار داده و آنها را به صورت توالی اعداد بر حسب یک لیست Balanced Block Randomization کدگزاری می نماید و هنگام ورود بیمار واجد شرایط مطالعه، داروی کد گزاری شده با یک برچسب که شامل کد عددی دارو، نام بیمار و کد مطالعه می باشد، در اختیار پزشک درمان گر بیمار قرار خواهد داد . غیر از فرد فوق همه افراد تیم پژوهش شامل پزشک درمان گر، مسئول جمع آوری کننده اطلاعات و آنالیزور، تحلیل کننده و خود بیمار از نوع دارو آگاه نیستند.

    گروه مداخله: بیماران کاندید پیوند آلوژن که شرایط ورود به مطالعه را دارند قرص NAC به صورت خوراکی (200 میلی گرمی) و با دوز 400 mg 3 بار در روز و دوز توتال 1200 میلی گرم روزانه از یک هفته قبل از پیوند تا یکماه بعد از پیوند ( -7 تا +30 ) به شرط عدم عود بیماری یا عوارض غیر قابل تحمل دریافت می کنند.

    گروه کنترل : همه بیمارانی که از سال 2014 تا 2020 با پروتکل استاندارد پیوند هاپلوایدنتیکال تحت پیوند قرار گرفته اند به عنوان گروه کنترل گذشته نگر در نظر گرفته می شود.
    گروه کنترل: بیماران کاندید پیوند آلوژن که شرایط ورود به مطالعه را دارند پلاسبو را سه بار در روز از یک هفته قبل از پیوند تا یکماه بعد از پیوند ( -7 تا +30 ) به شرط عدم عود بیماری یا عوارض غیر قابل تحمل دریافت می کنند.
