Effectiveness of the Nugent Score System in the diagnosis of bacterial vaginosis
Keywords:
Vaginosis bacteriana, criterios de Amsel, prueba de Nugent, infección vaginal, diagnóstico.Abstract
Background: the bacterial vaginosis is the commonest cause of vaginal infection.
Objective: to establish the diagnostic effectiveness of the Nugent test in the bacterial vaginosis diagnosis.
Methods: a transversal study of evaluation of diagnostic tests in a universe of 26 patients diagnosed with bacterial vaginosis according to the Amsel criteria, in the the "Luis Enrique de la Paz Reyna" clinic in Yara, Granma. Age, risk factors, results of the perspired vaginal and results of the Nugent test were identified.
Results: from 26 patients diagnosed with bacterial vaginosis the average age was 29, 31 years. The most found risk factor was the inadequate genital toilet technique (76,92 %). The perspired vaginal result gave positive to Gardenella vaginalis in 88,47 %. The analysis of the results of the Nugent test, by means of the construction of the ROC curve, was in under the curve area of 98,72 % (IC 95 %: 95,83 %; 100 %), with standard error of 0,0083.
Conclusions: the bacterial vaginosis is diagnosed mainly in very young adults, taking into account the inadequate techniques of toilet, being the main risk factor. A high percentage of Gardenella vaginalis positive cultivations was obtained. The Nugent punctuation system resulted in a test with a high diagnostic capacity.
