ABSTRACT
OBJETIVO: El microorganismo Mycoplasma genitalium se ha relacionado con la uretritis no gonocócica (UNG). La técnica de PCR se ha convertido en el principal método de detección de este patógeno. En consecuencia, debe aplicarse un método de diagnóstico mediante la amplificación de fragmentos de ADN por la técnica PCR. MATERIAL Y MÉTODOS: Se seleccionaron los cebadores MGF-MGR y MgPaF-MgPaR, complementarios de los genes de ARNr 16S y MgPa de M. genitalium, respectivamente. Se efectuaron ensayos de especificidad y sensibilidad y se estudiaron muestras clínicas. RESULTADOS: La PCR con cada grupo de cebadores utilizado fue específica sólo para M. genitalium y la sensibilidad fue mayor con el grupo de cebadores MGF-MGR. En el estudio de 34 muestras clínicas, 18.5por ciento fue positivo a M. genitalium y se encontró un mayor número de muestras positivas al utilizar los cebadores MgPaF-MgPaR. CONCLUSIONES: Debe aplicarse en la práctica clínica el diagnóstico de M. genitalium mediante la amplificación del ADN por PCR en los pacientes con UNG(AU)
OBJECTIVE: Mycoplasma genitalium has been associated with nongonococcal urethritis (NGU). Diagnosis by PCR has become the primary detection method for this organism. Thus, diagnosis by DNA amplification using the PCR technique should be utilized. MATERIAL AND METHODS: GMF/GMR and MgpF/MgpR primer pairs, complementary to the M. genitalium 16S rRNA and MgPa genes, respectively, were selected. Specificity and sensibility assays were conducted and clinical samples were studied. RESULTS: The PCR with each primer pair was specific only for M. genitalium, and the sensibility was higher with the GMF/GMR primers. In the study of 34 clinical samples, 18,5percent were positive for M. genitalium, with more positive samples when the MgpF/MgpR primers were used. CONCLUSIONS: DNA amplification by PCR should be applied in clinical practice to the diagnosis of M. genitalium in patients with NGU should using(AU)

OBJECTIVE: To compare the epidemiology and hospital course of patients with acute salpingitis with and without coincident human immunodeficiency virus (HIV) seropositivity. METHODS: Patients admitted to the UMDNJ-University Hospital in Newark, New Jersey from January 1, 1991, to December 31, 1991, with acute salpingitis were studied. RESULTS: Eight percent of all hospitalized patients with acute salpingitis were HIV-positive. The mean age of the HIV-negative group was 25.4 compared with 29.6 years in the HIV-positive group. Gonorrhea and chlamydia were present in 49% and 22%, respectively, in HIV-negatives and in 40% and 20% of HIV-positives. Two of 5 (40%) HIV-positive patients had tuboovarian abscesses compared with 12 of 59 (20%) HIV-negative patients. Three of 5 (60%) HIV-positive patients had admission WBC counts fewer than 10,000/mm(3) compared to 6 of 59 (12%) of HIV-negatives (P = 0.024). The hospital stay was 5.4 days for HIV-positives and 5.8 days for HIV-negatives. CONCLUSIONS: Eight percent of hospitalized patients with acute salpingitis were HIV-seropositive. Neisseria gonorrhoeae and chlamydia were commonly found organisms in both groups. The initial WBC count was lower for HIV-positive patients. The hospital course of both groups was similar.
