چکیده

مقدمه: واژینوز باکتریال، شایع‌ترین نوع واژینیت در زنان سنین باروری است که توسط معیارهای بالینی آمسل و یا سیستم نمره‌دهی میکروسکوپی ناجنت (رنگ‌آمیزی گرم)، تشخیص داده می‌شود. مطالعه حاضر با هدف مقایسه معیارهای بالینی آمسل با روش استاندارد رنگ‌آمیزی گرم در تشخیص واژینوز باکتریال انجام شد.
روش‌کار: این مطالعه تجربی به‌منظور مقایسه معیارهای بالینی آمسل با روش استاندارد رنگ‌آمیزی گرم در تشخیص واژینوز باکتریال در سال 95-1394 بر روی 100 زن متأهل مراجعه‌کننده به درمانگاه‌های زنان شهر خرم‌آباد انجام شد. سیستم نمره‌دهی ناجنت به‌عنوان روش تشخیصی استاندارد طلایی واژینوز باکتریال در نظر گرفته شد. حساسیت، ویژگی، ارزش اخباری مثبت و ارزش اخباری منفی معیارهای آمسل با سیستم نمره‌دهی ناجنت مقایسه گردید. تجزیه و تحلیل داده‌ها با استفاده از نرم‌افزار آماری SPSS (نسخه 20) انجام شد. میزان p‌ کمتر از 05/0 معنی‌دار در نظر گرفته شد.
یافته‌ها: میانگین سن، طول مدت ازدواج، سن اولین قاعدگی و اولین بارداری واحدهای پژوهش به ترتیب 93/8±96/31، 50/3± 96/18، 85/0±99/12 و 84/3±03/20 سال بود. در ارزیابی ارزش تشخیصی سیستم نمره‌دهی ناجنت در مقایسه با معیارهای آمسل، معیارهای آمسل دارای حساسیت 100%، ویژگی 46%، ارزش اخباری مثبت 5/92% و ارزش اخباری منفی 100% بود.
نتیجه‌گیری: معیارهای آمسل به‌اندازه سیستم امتیازدهی ناجنت در تشخیص این عفونت دقت ندارند و رنگ­آمیزی گرم برای تشخیص صحیح واژینوز باکتریال نیاز است.

چکیده [English]

Introduction: Bacterial Vaginosis is the most common type of vaginitis in women of reproductive age which is diagnosed by Amsel’s clinical criteria and the Nugent microscopic scoring system (Gram stain). This study was performed with aim to compare Amsel clinical criteria with standard method of Gram stain for diagnosis of bacterial vaginosis.
Methods: The experimental study was conducted to compare Amsel's clinical criteria with standard gram stain method for diagnosis of bacterial vaginosis on 100 married women referred to women clinics of Khorramabad in 2015-2016. Nugent scoring system was considered as the gold standard method for diagnosis of bacterial vaginosis. Sensitivity, specificity, positive predictive value, and negative predictive value of Amsel's criteria was compared with those of the Nugent scoring system. Data was analyzed by SPSS software (version 20). P<0.05 was considered statistically significant.
Results: The mean of age, duration of marriage, age of the first menstruation and first pregnancy were 31.96 ± 8.93, 18.96 ± 3.50, 12.99± 0.85, and 20.03 ± 3.84 years. In the evaluation of diagnostic value of the Nugent scoring system in comparison with the Amsel's criteria, Amsel's criteria had sensitivity 100%, specificity 46%, positive predictive value 92.5%, and negative predictive value of 100%.
Conclusion: Amsel's criteria are not as accurate as the Nugent scoring system in the diagnosis of this infection and Gram staining is needed to correctly diagnose bacterial vaginosis.
