Actinomyces odontolyticusinfection 3 months post-robotic-assisted laparoscopic prostatectomy

Abstract

Actinomyces odontolyticus infection is a rare bacterial infection with only 46 cases reported from its discovery in 1958. This case highlights an immunocompetent patient who presented with an infected lymphocele and bacteraemia following a robotic-assisted laparoscopic prostatectomy and extended pelvic lymph node dissection 3 months previously. He was treated for a fever of unclear origin initially using amoxicillin, gentamicin and metronidazole. Subsequently, he was found to have an infected lymphocele, which required surgical drainage. He was discharged 19 days after admission with three times daily oral amoxicillin which is to be continued for 6–12 months. This case highlights the need for effective communication between the laboratory and medical teams, and the importance of prompt source control.

Infección intraabdominal por actinomyces odontolyticus tras bypass gástrico laparoscópico

“…Hay pocos casos descritos en la literatura sobre actinomicosis abdominal. De hecho, sólo hay 47 casos descritos en la literatura de infecciones producidas por Actinomyces odontolyticus (10). Actinomices es una bacteria saprofita de la cavidad oral, tracto gastrointestinal y aparato genital femenino (7).…”

“…Como factores de riesgo se encuentran la inmunosupresión, la hipoproteinemia y la diabetes (4). Es poco frecuente que un paciente inmunocompetente pueda presentar una infección por actinomices (10). En nuestro caso se trata de una paciente mujer inmunocompetente, que presenta una ruptura de la barrera mucosa gástrica en dos ocasiones.…”

“…Sin embargo, la forma de afectación descrita es por afectación de la pared gástrica por actinomyces, sin que el germen pase a la cavidad abdominal. En segundo lugar, la cepa de actinomyces causante del proceso infeccioso es poco frecuente, de hecho, es el segundo caso descrito en la literatura de infección por A. odontolyticus en una paciente inmunocompetente (10).…”

Infecciones abdominales por Actinomyces odontolyticus: comunicación de dos casos

“…La incidencia mundial es de un caso en 300.000 habitantes 9 . La forma de presentación más común es el compromiso de la región cervicofacial, pero también puede haber compromiso torácico, pélvico, abdominal y del sistema nervioso central 3 .…”

Sepsis due to Actinomyces odontolyticus as a Rare Complication of Neobladder

“…While multiple forms of A. odontolyticus culture-positive invasive infections have been reported, the incidence of A. odontolyticus bacteremia remains extremely rare. Immunosuppression is essential or having a significant risk factor for infection, including poor oral hygiene, intravenous drug use, and previous mucosal manipulation to develop bacteremia with A. odontolyticus [ 4 – 6 ]. Gram staining and pathology of infected tissue is usually more sensitive than the culture since it is often difficult to identify in the lab and can be culture-negative and might remain sterile in more than 50% of cases, but when combined with immunofluorescence technique, they provide a highly specific diagnosis [ 7 ].…”
