چکیده

مقدمه: 35-10 درصد از جمعیت بزرگسالان سراسر جهان به بیماری کبد چرب غیر الکلی مبتلا می‌باشند. تا کنون هیچ درمان قطعی برای این بیماری پیشنهاد نشده است. اسیدهای چرب امگا 3 درای اثرات مفیدی در درمان هایپرلیپیدمی و بیماری‌های قلبی- عروقی می‌باشند و به تازگی برای درمان بیماری کبد چرب غیر الکلی استفاده می‌شوند. هدف از این مطالعه، مرور مطالعاتی بود که نقش اسیدهای چرب امگا 3 در پیشگیری و درمان بیماری کبد چرب غیر الکلی را بررسی کرده بودند.روش‌ها: ابتدا از پایگاه‌های PubMed و ISI مقالاتی که در متن خود دارای کلمات NAFLD (Non-alcoholic fatty liver disease)، NASH (Nonalcoholic steatohepatitis)، Nonalcoholic fatty liver، Steatosis، DHA (Docosahexaenoic acid)، EPA (Eicosapentaenoic acid)، Fish oil و 3Omega  بودند، جستجو شدند. سپس مقالات به سه دسته مطالعات حیوانی، مطالعات مقطعی و مورد- شاهدی و مطالعات کارآزمایی بالینی تقسیم‌بندی شدند که در مجموع، 21 مقاله مورد ارزیابی قرار گرفتند.یافته‌ها: نتایج مطالعات مقطعی و مورد- شاهدی همسو نبود، اما نتایج مطالعات قوی‌تر نشان می‌داد که دریافت ناکافی از منابع غذایی امگا 3 با بروز بیماری کبد چرب در ارتباط می‌باشد. بیشتر مداخلات انجام شده در مطالعات حیوانی و انسانی، تأثیر مثبتی از مصرف مکمل امگا 3 در کاهش تری گلیسیرید و چربی کبدی در مبتلایان به کبد چرب غیر الکلی گزارش کرده‌اند.نتیجه‌گیری: کاهش دریافت امگا 3 از منابع غذایی به دلیل عادات غذایی نادرست، می‌تواند یکی از دلایل چند عاملی بودن بیماری کبد چرب باشد. همچنین مصرف مکمل آن می‌تواند در کنار اصلاح الگوی غذایی و سبک زندگی برای این بیماران مفید باشد.

چکیده [English]

Background: 10 to 35% of the adult population all round the world is infected with nonalcoholic fatty liver disease (NAFLD). So far, no cure is recommended for this disease. Omega-3 fatty acids have beneficial effects in the treatment of hyperlipidemia and cardiovascular disease; the resort is recently used for the treatment of nonalcoholic fatty liver disease. The aim of this study was to review the studies about the role of omega-3 fatty acids on the prevention and treatment of nonalcoholic fatty liver disease.Methods: First, PubMed and ISI databases were searched for the papers in their text there were the words NAFLD, NASH, nonalcoholic fatty liver, steatosis, DHA, EPA, fish oil and omega 3. Then, the papers were divided into tree groups: animal studies, cross-sectional studies, and case-control studies and clinical trials. Totally, 21 articles were evaluated.Findings: The results of cross-sectional and case-control studies were not similar, but more robust studies showed that inadequate intakes of dietary sources of omega-3 was associated with fatty liver disease. Most interventions have been conducted in animal and human studies that have been reported positive effects of omega-3 supplementation in reducing triglycerides and fatty liver in patients with nonalcoholic fatty liver.Conclusion: According to the available evidence, it seems that reduction of omega-3 food sources due to poor eating habits can be one of the reasons of multi-factorial fatty liver disease. In addition, the use of omega-3 supplement along with modification of the diet pattern and lifestyle is beneficial for patients.
