NCT04626557

Brief Summary

To investigate if asthma affects the inflammatory balance of the endometrium and thereby interfere with implantation, as indicated by the characteristics of the inflammatory cells in the endometrium and airways in women with asthma who are referred for IUI or IVF due to infertility, compared to otherwise healthy women who are referred for IUI or IVF due to infertility.

Outcome Measures

Primary Outcomes (1)

  • type of inflammatory cells

    To classify the type of inflammatory cells, (ie. cytokines and inflammatory cells), found in the uterine lining (endometrium) in women with asthma suffering from infertility, compared to non-asthmatic controls.

    6 months

Secondary Outcomes (3)

  • airway inflammation vs inflammation in the endometrium.

    6 months

  • systemic inflammation vs local inflammation

    6 months

  • Severity

    6 months

Study Arms (2)

Women with astma

At the 7th -14th cycle day, an endometrium sample from the uterus lining will be obtained together with sputum, as indicators of the system inflammation expressed both in the lungs and the uterus, and blood samples.

Procedure: biopsy

Women without asthma

At the 7th - 14th cycle day, an endometrium sample from the uterus lining will be obtained together with sputum, as indicators of the system inflammation expressed both in the lungs and the uterus, and blood samples.

Procedure: biopsy

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

30 participants divided into two groups: 15 women with asthma and 15 non-asthmatic controls. The patients will go through an asthma work-up (diagnosis, allergy, medication, and inflammation). Menstrual blood will be collected at home using the menstrual cup and at the 7th-14th cycle day, an endometrium sample from the uterus lining will be obtained together with sputum, as indicators of the system inflammation expressed both in the lungs and the uterus, and blood samples.

You may qualify if:

  • Asthma n= 15:
  • Informed consent.
  • Diagnosis of asthma.
  • years.
  • Referred to Intra Uterine Insemination (IUI) or in vitro fertilization (IVF)
  • Non-asthmatic n= 15:
  • Informed consent.
  • years.
  • Referred to Intra Uterine Insemination (IUI) or in vitro fertilization (IVF)

You may not qualify if:

  • Asthma only:
  • Other respiratory diseases than asthma.
  • Other inflammatory disease or a disease that affects fertility.
  • Infections requiring antibiotics or anti-viral treatment within 30 days.
  • Current smokers and/or life-time tobacco exposure \> 10 pack-years.
  • Endometriosis.
  • Infertility due to other reasons than male factor, tubal factor or unexplained infertility.
  • No pelvic inflammatory disease (PID) within the last 6 months.
  • No contraceptive intrauterine device (IUD), or other contraceptive for the last 6 months.
  • Non-asthmatic controls:
  • No respiratory diseases.
  • Other inflammatory disease or a disease that affects fertility.
  • Infections requiring antibiotics or anti-viral treatment within 30 days.
  • Current smokers and/or life-time tobacco exposure \> 10 pack-years.
  • Endometriosis.
