Brief Summary:
Correlation between the presence of intracellular viruses/bacteria and the incidence of miscarriage during the first trimester of pregnancy.

Condition or disease Intervention/treatment
Pregnancy Loss Diagnostic Test: Spontaneous miscarriage Diagnostic Test: Voluntary pregnancy interruption

Detailed Description:

In this study we will analyse chorionic villi derived from abortion during the first trimester of pregnancy (spontaneous abortion vs voluntary pregnancy interruption), in order to correlate the presence of infective viruses/bacteria and the incidence of miscarriage.

The first objective of this project will be to find the viral DNA of HPV, BK and JC polyomaviruses and bacterial DNA of Chlamydia trachomatis, Ureaplasma parvum, Ureaplasma urealyticum, Mycoplasma hominis in the aborted tissues collected from spontaneous abortions, and to compare the prevalence of these DNAs to those derived from elective specimens.

DNA: deoxyribonucleic acid HPV: human papillomavirus PCR: polymerase chain reaction HPyV: human polyomavirus PBMC: peripheral blood mononucleated cell BKV: BK polyomavirus JCV: JC polyomavirus

Primary Outcome Measures :
  1. Individuation of DNA of intracellular agents (viral und bacterial) in chorionic tissue und blood sample. [ Time Frame: December 2014 - April 2017 ]
    The primary outcome of this project is to find the DNA of viral (HPV, HPyV,BK and JC), or bacterial agents (Chlamydia trachomatis, Ureaplasma parvum, U. urealyticum, Mycoplasma hominis) in samples obtained from spontaneous abortion or elective interruption of pregnancy.


Biospecimen Retention:   Samples With DNA

All samples, both spontaneous (spontaneous miscarriage) and elective (voluntary interruption of pregnancy), will be obtained after uterine cavity curettage.

All women underwent PBMC extraction from peripheral whole blood.
