ALICE
Analysis of Infectious Chronic Endometritis

 ALICE detects the bacteria causing chronic endometritis to improve your patient's reproductive outcome

Overview

  • Chronic endometritis is a persistent inflammation of the endometrial lining caused by the infection of the uterine cavity, mainly by bacterial pathogens.
  • Independent studies show that this condition affects up to 30% of infertile patients, and in cases of repeated implantation failure or recurrent pregnancy loss, this can rise to 66%*.

  • According to our scientific publication The diagnosis of chronic endometritis in infertile asymptomatic women: a comparative study of histology, microbial cultures, hysteroscopy, and molecular microbiology, ALICE method is similar in reliability to the three classic diagnostic methods.

    Moreno et al. Am J Obstet Gynecol. 2018, DOI: 10.1016/j.ajog.2018.02.012.

ALICE can be performed on a small piece of endometrial biopsy.

If the patient is undergoing an ERA test, a small portion of the same biopsy can be used, so no additional sample will be required.

Benefits

  • ALICE is a diagnostic test to detect and quantify the eight most common pathogenic bacteria causing chronic endometritis, recommending appropriate antibiotic and probiotic treatment.
  • ALICE microbiology method allows the identification of culturable and nonculturable endometrial pathogens associated with chronic endometritis
  • If ALICE tests positive, the report will focus on the detection of those specific bacteria causing said condition.
  • A list with the recommended antibiotics and probiotics will be provided depending on ALICE results.
  • Microbiology counseling will be available. 
  • Histology is the current gold-standard method for the assessment of CE.
  • Only microbial culture can provide information about the causative infectious agents.
  • It has been demonstrated that between 20 and 60% of bacteria cannot be cultured or are not assessed in the clinical setting. Among them, Gardnerella vaginalis, one of the most common pathogens of the reproductive tract, is not culturable under the standard microbiological methods. The molecular assessment of the microbiome using NGS allows to detect culturable and non-culturable bacteria.
  • Una serie de muestras analizadas mediante histología, histeroscopia y cultivo microbiano obtuvieron una concordancia del 20% en los resultados obtenidos. El análisis mediante NGS obtuvo coincidencia para el 78% de las muestras analizadas.

Indications

ALICE can be beneficial for any patient wishing to conceive, by assessing the microbiological environment that the embryo will encounter at implantation.

ALICE may also be beneficial for patients with a history of recurrent pregnancy loss or recurrent implantation failure because chronic endometritis has been linked to these events.

Indications

Technology

ALICE uses the latest Next Generation Sequencing technology to provide microbiome information in endometrial tissue by analyzing the abundance of specific bacteria causing chronic endometritis.
