    • Objective: To investigate plasma steroid hormone levels in postmenopausal breast cancer patients with and without adjuvant endocrine therapy and in healthy postmenopausal women.Methods: Steroid hormone levels in postmenopausal breast cancer patients treated with aromatase inhibitors (n = 32) were compared with breast cancer patients treated with tamoxifen (n = 34), breast cancer patients without adjuvant endocrine therapy (n = 15), and healthy postmenopausal women (n = 56). Pregnenolone, 17-hydroxypregnenolone, 17-hydroxyprogesterone, 11-deoxycortisol, cortisol, cortisone, dehydroepiandrosterone (DHEA), androstenedione, total testosterone, dihydrotestosterone, estrone and estradiol were measured using liquid chromatography-tandem mass spectrometry. Sex hormone binding globulin was measured by solid-phase chemiluminescent immunometric assays, and the free androgen index was calculated.Results: Aromatase inhibitor users did not differ in dihydrotestosterone, total testosterone, androstenedione, DHEA, or free androgen index levels from healthy controls or untreated breast cancer patients. The highest total testosterone levels were found in tamoxifen-treated women, who had significantly higher plasma concentrations than both women treated with aromatase inhibitors and breast cancer patients without adjuvant treatment. Concentrations of cortisol and cortisone were significantly greater in aromatase inhibitor users as well as tamoxifen users, in comparison with healthy controls and untreated breast cancer patients. Aromatase inhibitor users had lower estrone and estradiol plasma concentrations than all other groups.Conclusion: Adjuvant treatment with aromatase inhibitors or tamoxifen was associated with increased cortisol and cortisone plasma concentrations as well as decreased estradiol concentrations. Androgen levels were elevated in tamoxifen-treated women but not in aromatase inhibitor users.

  • Sexual dysfunction in women on adjuvant endocrine therapy after breast cancer
  • 2013
  • Ingår i: Menopause. - : Lippincott Williams & Wilkins. - 1072-3714 .- 1530-0374. ; 20:2, s. 162-168

    • Objective: The goal of this study was to investigate sexual function in postmenopausal breast cancer patients treated with aromatase inhibitors.Methods: A population-based, cross-sectional study was conducted among postmenopausal breast cancer patients on adjuvant endocrine treatment and age-matched controls with and without estrogen treatment. Sexual function was assessed with a standardized questionnaire.Results: In all, 42.4% of aromatase inhibitor-treated breast cancer patients were dissatisfied with their sex life in general, and 50.0% reported low sexual interest; this was significantly more common than in tamoxifen-treated patients and controls (P < 0.05). Aromatase inhibitorYtreated patients reported insufficient lubrication in 73.9% and dyspareunia in 56.5% of cases, which were significantly more common than in controls, irrespective of hormonal use (P < 0.05). Tamoxifen-treated patients reported significantly more dyspareunia (31.3%; P < 0.05) but resembled controls in all other concerns.Conclusions: Our findings suggest that sexual dysfunction in aromatase inhibitorYtreated women is a greatly underestimated problem.

  • Urogenital disorders in women with adjuvant endocrine therapy after early breast cancer
  • 2011
  • Ingår i: American Journal of Obstetrics and Gynecology. - : Elsevier BV. - 0002-9378 .- 1097-6868. ; 204:1, s. 26.e1-7

    • OBJECTIVE: To investigate the prevalence of urogenital symptoms and vaginal atrophy in postmenopausal breast cancer patients on adjuvant endocrine therapy. STUDY DESIGN: A population-based, cross-sectional study on postmenopausal breast cancer patients on adjuvant endocrine treatment and age-matched control subjects. Vaginal atrophy was assessed by gynecologic examination and atrophy-related symptoms by validated questionnaires. RESULTS: In all, 57.6% of aromatase inhibitor-treated and 32.4% of tamoxifen-treated breast cancer patients rated at least 1 vaginal atrophy symptom as moderate/severe, which was significantly more common than in control subjects (P < .01). Aromatase inhibitor-treated patients more often had moderate or severe vaginal atrophy (P < .05), a more atrophic cytohormonal evaluation, and significantly higher vaginal pH (P < .05) than all control subjects, irrespective of hormonal use. CONCLUSION: Our findings indicate that the frequency of vaginal atrophy symptoms, particularly in aromatase inhibitor-treated women, might have been underestimated in previous clinical trials.

  • Ongoing or previous mental disorders predispose to adverse mood reporting during combined oral contraceptive use
  • 2018
  • Ingår i: European Journal of Contraception and Reproductive Health Care. - : Informa UK Limited. - 1362-5187 .- 1473-0782. ; 23:1, s. 45-51
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Previous studies have emphasised that women with pre-existing mood disorders are more inclined to discontinue hormonal contraceptive use. However, few studies have examined the effects of combined oral contraceptives (COC) on mood in women with previous or ongoing mental disorders. Materials and methods: This is a supplementary analysis of an investigator-initiated, double-blinded, randomised clinical trial during which 202 women were treated with either a COC (1.5mg estradiol and 2.5mg nomegestrolacetate) or placebo during three treatment cycles. The Mini International Neuropsychiatric Interview was used to collect information on previous or ongoing mental disorders. The primary outcome measure was the total change score in five mood symptoms on the Daily Record of Severity of Problems (DRSP) scale in the intermenstrual phase of the treatment cycle. Results: Women with ongoing or previous mood, anxiety or eating disorders allocated to COC had higher total DRSP -scores during the intermenstrual phase of the treatment cycle in comparison with corresponding women randomised to placebo, mean difference 1.3 (95% CI 0.3-2.3). In contrast, among women without mental health problems, no difference in total DRSP -scores between COC- and placebo users was noted. Women with a risk use of alcohol who were randomised to the COC had higher total DRSP -scores than women randomised to placebo, mean difference 2.1 (CI 95% 1.0-3.2). Conclusions: Women with ongoing or previous mental disorders or risk use of alcohol have greater risk of COC-induced mood symptoms. This may be worth noting during family planning and contraceptive counselling.

  • Expression of calcium release-activated and voltage-gated calcium channels genes in peripheral blood mononuclear cells is altered in pregnancy and in type 1 diabetes
  • 2018

    • Calcium (Ca2+) is an important ion in physiology and is found both outside and inside cells. The intracellular concentration of Ca2+ is tightly regulated as it is an intracellular signal molecule and can affect a variety of cellular processes. In immune cells Ca2+ has been shown to regulate e.g. gene transcription, cytokine secretion, proliferation and migration. Ca2+ can enter the cytoplasm either from intracellular stores or from outside the cells when Ca2+ permeable ion channels in the plasma membrane open. The Ca2+ release-activated (CRAC) channel is the most prominent Ca2+ ion channel in the plasma membrane. It is formed by ORAI1-3 and the channel is opened by the endoplasmic reticulum Ca2+ sensor proteins stromal interaction molecules (STIM) 1 and 2. Another group of Ca-2(+) channels in the plasma membrane are the voltage-gated Ca2+ (Ca-V) channels. We examined if a change in immunological tolerance is accompanied by altered ORAI, STIM and Ca-V gene expression in peripheral blood mononuclear cells (PBMCs) in pregnant women and in type 1 diabetic individuals. Our results show that in pregnancy and type 1 diabetes ORAI1-3 are up-regulated whereas STIM1 and 2 are down-regulated in pregnancy but only STIM2 in type 1 diabetes. Expression of L-, P/Q-, R- and T-type voltage-gated Ca2+ channels was detected in the PBMCs where the Ca(V)2.3 gene was up-regulated in pregnancy and type 1 diabetes whereas the Ca(V)2.1 and Ca(V)3.2 genes were up-regulated only in pregnancy and the Ca(V)1.3 gene in type 1 diabetes. The results are consistent with that expression of ORAI, STIM and Ca-V genes correlate with a shift in immunological status of the individual in health, as during pregnancy, and in the autoimmune disease type 1 diabetes. Whether the changes are in general protective or in type 1 diabetes include some pathogenic components remains to be clarified.

    • The amino acid glutamate opens cation permeable ion channels, the iGlu receptors. These ion channels are abundantly expressed in the mammalian brain where glutamate is the main excitatory neurotransmitter. The neurotransmitters and their receptors are being increasingly detected in the cells of immune system. Here we examined the expression of the 18 known subunits of the iGlu receptors families; alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), kainate, N-methyl-D-aspartate (NMDA) and delta in human peripheral blood mononuclear cells (PBMCs). We compared the expression of the subunits between four groups: men, non-pregnant women, healthy pregnant women and depressed pregnant women.Out of 18 subunits of the iGlu receptors, mRNAs for 11 subunits were detected in PBMCs from men and nonpregnant women; AMPA: GluA3, GluA4, kainate: GluK2, GluK4, GluK5, NMDA: GluN1, GluN2C, GluN2D, GluN3A, GluN3B, and delta: GluD1. In the healthy and the depressed pregnant women, in addition, the delta GluD2 subunit was identified. The mRNAs for GluK4, GluK5, GluN2C and GluN2D were expressed at a higher level than other subunits. Gender, pregnancy or depression during pregnancy altered the expression of GluA3, GluK4, GluN2D, GluN3B and GluD1 iGlu subunit mRNAs. The greatest changes recorded were the lower GluA3 and GluK4 mRNA levels in pregnant women and the higher GluN2D mRNA level in healthy but not in depressed pregnant women as compared to non-pregnant individuals. Using subunit specific antibodies, the GluK4, GluK5, GluNl, GluN2C and GluN2D subunit proteins were identified in the PBMCs. The results show expression of specific iGlu receptor subunit in the PBMCs and support the idea of physiology-driven changes of iGlu receptors subtypes in the immune cells.

    • AimThe concept of nerve-driven immunity recognizes a link between the nervous and the immune system. -aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain, and receptors activated by GABA can be expressed by immune cells. Here, we examined whether the expression of GABA receptors and chloride transporters in human peripheral blood mononuclear cells (PBMCs) was influenced by gender, pregnancy or mental health. MethodsWe used RT-qPCR to determine the mRNA expression level in PBMCs from men (n=16), non-pregnant women (n=19), healthy pregnant women (n=27) and depressed pregnant women (n=15). ResultsThe 2 subunit had the most prominent expression level of the GABA-A receptor subunits in all samples. The and 2 subunits were up-regulated by pregnancy, whereas the epsilon subunit was more frequently expressed in healthy pregnant women than non-pregnant women who, in turn, commonly expressed the 6 and the 2 subunits. The 1 and epsilon subunits expression was altered by depression in pregnant women. The GABA-B1 receptor was up-regulated by depression in pregnant women, while the transporters NKCC1 and KCC4 were down-regulated by pregnancy. The changes recorded in the mRNA expression levels imply participation of GABA receptors in establishing and maintaining tolerance in pregnancy. Importantly, the correlation of mental health with the expression of specific receptor subunits reveals a connection between the immune cells and the brain. Biomarkers for mental health may be identified in PBMCs. ConclusionThe results demonstrate the impact gender, pregnancy and mental health have on the expression of GABA receptors and chloride transporters expressed in human PBMCs.

  • Socioeconomic characteristics, housing conditions and criminal offences among women with cervical neoplasia
  • 2013
  • Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - : Wiley. - 0001-6349 .- 1600-0412. ; 92:8, s. 888-894

    • Objective. To investigate the association between cervical neoplasia and socioeconomic factors, housing conditions and criminal offences. Design. Longitudinal observational study. Setting. Falun county hospital, Sweden. Population. A total of 1331 women diagnosed with cervical intraepithelial neoplasia I-III or cervical cancer between 1967 and 1978 were compared with 2604 age-matched controls from the same geographical area in Sweden. Methods. The Population and Housing Censuses were used for information about civil status, education, housing conditions, employment and socioeconomic status. The Swedish Register of Conviction Decisions was used to access information on criminal offences. Main outcome measures. Socioeconomic status, housing conditions, criminal offences. Results. Women with cervical neoplasia had a lower socioeconomic status and a lower educational level than their age-matched controls. They were more often divorced and did not own their home as often as controls. A significant association with criminal offences was observed, and it persisted after adjustment for socioeconomic status. Differences in socioeconomic factors between women with cervical neoplasia and their controls had not diminished in the younger, compared with the older, part of the study population. Conclusions. The results indicate that women with cervical neoplasia belong to a socioeconomically disadvantaged group. Furthermore, the study provides information about an association with criminal offences.
