Sexual health in Belgian cervical cancer survivors: an exploratory qualitative study.

PURPOSE: To assess experiences of sexuality and of receiving sexual healthcare in cervical cancer (CC) survivors. METHODS: A qualitative phenomenological study using semistructured one-on-one interviews was conducted with 15 Belgian CC survivors recruited in 5 hospitals from August 2021 to February 2022. The interviews were audiotaped and transcribed verbatim. Data were analyzed using inductive thematic analysis. COREQ and SRQR reporting guidelines were applied. RESULTS: Most participants experienced an altered sexuality after CC treatment with often long-term loss/lack of sex drive, little/no spontaneity, limitation of positions to avoid dyspareunia, less intense orgasms, or no sexual activity at all. In some cases, emotional intimacy became more prominent. Physical (vaginal bleeding, vaginal dryness, dyspareunia, menopausal symptoms) and psychological consequences (guilt, changed self-image) were at the root of the altered sexuality. Treatment-induced menopause reduced sex drive. In premenopausal patients, treatment and/or treatment-induced menopause resulted in the sudden elimination of family planning. Most participants highlighted the need to discuss their altered sexual experience with their partner to grow together toward a new interpretation of sexuality. To facilitate this discussion, most of the participants emphasized the need for greater partner involvement by healthcare providers (HPs). The oncology nurse or sexologist was the preferred HP with whom to discuss sexual health. The preferred timing for information about the sexual consequences of treatment was at treatment completion or during early follow-up. CONCLUSION: Both treatment-induced physical and psychological experiences were prominent and altered sexuality. Overall, there was a need for HPs to adopt proactive patient-tailored approaches to discuss sexual health.

Vaginal morbidity, sexual functioning, and health-related quality of life in cervical cancer survivors: a cross-sectional multicenter study (VAMOS).

PURPOSE: To compare sexual/vaginal functioning between early cervical cancer (ECC) and locally advanced cervical cancer (LACC) survivors. METHODS: VAMOS was a multicenter, cross-sectional, questionnaire, noninferiority study including ECC patients treated with surgery and, if clinically indicated, adjuvant (chemo)radiotherapy and LACC patients treated with neoadjuvant (chemo)radiotherapy followed by surgery. Patient-reported outcomes (PROs) were assessed using the EORTC QLQ-C30, EORTC QLQ-CX24, and Female Sexual Functioning Index (FSFI) questionnaires. Clinical reported outcomes (ClinROs) consisted of vaginal morbidity scored according to the CTCAE v4.0 scoring system. RESULTS: One hundred forty-three patients were included. Compared to ECC patients (n = 97), LACC patients (n = 46) were significantly less sexually active in the 4 weeks prior to completion of the questionnaires (65% vs. 41%; p = .005). The primary endpoint was not met: LACC patients reported a higher mean score (more problems) for sexual/vaginal functioning than ECC patients, with a non-clinically relevant mean difference of 6.38 ([95% CI: - 6.41, 19.17]; p = .570 for noninferiority). Regarding the secondary endpoints, the prevalence of sexual dysfunction between the two groups did not differ significantly (p = 0.124). Compared to ECC patients, LACC patients did not have significantly more vaginal morbidity (adjusted odds ratio [OR] 1.51 [95% CI: 0.22, 10.29]; p = .674). Moreover, there was poor agreement between any vaginal morbidity and sexual dysfunction (Cohen's kappa of 0.17). CONCLUSION: Compared to ECC survivors, LACC survivors were significantly less sexually active and reported equivalent or worse sexual/vaginal functioning, although the proportion of patients with sexual dysfunction was similar. Clinical assessment of vaginal morbidity was poorly correlated with sexual dysfunction.

Pertussis Immunization During Pregnancy: Assessment of the Role of Maternal Antibodies on Immune Responses in Term and Preterm-Born Infants.

BACKGROUND: Limited data exist on the impact of maternal tetanus, diphtheria, acellular pertussis (Tdap) vaccination for preterm born infants. We report its effect at birth and on antibody-mediated immune responses to a DTaP-IPV-HB-PRP~T vaccine in preterm compared with term infants. METHODS: Women delivering at term or prematurely were either vaccinated with a Tdap vaccine (Boostrix; GSK) during pregnancy or not vaccinated in the last 5 years. Cord and maternal blood were collected at delivery. Infants were vaccinated with DTaP-IPV-HB-PRP~T vaccine (Hexyon; Sanofi Pasteur) and blood collected before and 1 month after primary (8-12-16 weeks) and before and 1 month after booster vaccination (13 or 15 months for preterm and term, respectively). Immunoglobulin G antibodies against all antigens included in DTaP-IPV-HB-PRP~T vaccine were measured (NCT02511327). RESULTS: Cord blood geometric mean concentrations (GMCs) in preterm infants from Tdap-vaccinated women were significantly higher than in term and preterm infants from unvaccinated women. A longer time interval between maternal vaccination and delivery resulted in higher cord blood GMCs in preterm infants. Equal GMCs in term and preterm infants from Tdap-vaccinated women were observed after primary vaccination. After boosting, significantly lower GMCs were seen for pertussis toxin, filamentous hemagglutinin, and tetanus toxoid in preterm compared with term infants from Tdap-vaccinated women, yet still comparable to GMCs in both term and preterm infants from unvaccinated women. CONCLUSIONS: Preterm infants profit from maternal Tdap vaccination. Prematurity did not influence primary immune responses in the presence of maternal antibodies but was associated with a lower booster immune response.

Impact of Maternal Pertussis Antibodies on the Infants' Cellular Immune Responses.

INTRODUCTION: Maternal antibody interference of the infant's humoral immune responses raises some concern to the strategy of maternal Tdap (tetanus, diphtheria, acellular pertussis [aP]) vaccination. This study assessed the impact of maternal Tdap antibodies on the infant's pertussis-specific T lymphocyte responses following infant vaccination with an aP containing vaccine, in a term and preterm born cohort. METHODS: Heparin samples (±0.5 mL) were conveniently drawn from infants of a Belgian prospective cohort study (N = 79, NCT02511327), including Tdap vaccinated (Boostrix®) and nonvaccinated women (no Tdap vaccine in the last 5 years) that delivered at term or prematurely. Sampling was performed before and 1 month after primary (8-12-16 weeks) and booster vaccination (13 or 15 months) with DTaP-IPV-HB-PRP~T vaccine (Hexyon®). Pertussis toxin (PT)-specific CD3+, CD3+ CD4+ and CD3+ CD8+ lymphoblasts and their cytokine secretions were measured using a flow cytometric assay on whole blood (FASCIA) and multiplex technology (Meso Scale Discovery), respectively. RESULTS: In total, 57% of all infants were considered PT-specific CD3+ CD4+ lymphoblasts responders after primary and booster vaccination, whereas 17% were CD3+ CD8+ lymphoblast responders. Interferon (IFN)-γ, interleukin (IL)-13, IL-17A, and IL-5 cytokine secretions after primary and booster vaccination were indicative of a mixed T helper (Th) 1/Th2/Th17 cell profile. Lymphoblast and cytokine levels were comparable between term and preterm infants. Nonresponders for IL-13 after booster vaccination had higher maternal PT immunoglobulin G (IgG) levels at birth when compared to responders. CONCLUSIONS: Term and preterm born infants are capable of inducing Th1, Th2, and Th17 responses after aP vaccination, yet maternal vaccination modulate these responses. Evaluation of this effect in larger trials is needed.

Breast Milk Antibody Levels in Tdap-Vaccinated Women After Preterm Delivery.

BACKGROUND: Enrichment of breast milk (BM) with immunoglobulin (Ig) A and IgG through maternal vaccination could help infants combat targeted pathogens. However, evidence on this effect after preterm delivery is lacking. In this study, we investigated the total and anti-pertussis toxin (anti-PT)-specific IgA and IgG production in BM after term and preterm delivery in the presence of maternal Tdap (tetanus, diphtheria, acellular pertussis) vaccination. METHODS: Serum and BM samples of lactating women who delivered at term or prematurely and did or did not receive Tdap vaccine (Boostrix, GSK Biologicals) during pregnancy were collected as part of a clinical study (N = 234). Anti-PT IgA/IgG (IBL assay; Meso Scale Discovery assay) and total IgA/IgG (Thermofisher, on BM samples only) immunosorbent assays were performed on all samples collected at 72 hours and 4, 8, and 12 weeks postpartum. RESULTS: BM after preterm delivery contained anti-PT IgA and IgG geometric mean concentrations (GMCs) comparable to those after term delivery (eg, colostrum anti-PT IgA, 5.39 IU/mL vs 6.69 IU/mL, respectively). Maternal Tdap vaccination induced significantly higher anti-PT IgG GMCs in colostrum of vaccinated compared with unvaccinated women who delivered at term (0.110 IU/mL vs 0.027 IU/mL, P = .009). Anti-PT antibodies persisted up to 12 weeks postpartum. CONCLUSIONS: This study provides evidence that maternal Tdap vaccination induces high Ig levels in BM after both term and preterm delivery and that these antibodies remain abundantly present throughout lactation, possibly offering additional mucosal protection during the most vulnerable period in early life. CLINICAL TRIAL REGISTRATION: NCT02511327.

The effect of maternal antibodies on the cellular immune response after infant vaccination: A review.

During the last few decades, maternal immunization as a strategy to protect young infants from infectious diseases has been increasingly recommended, yet some issues have emerged. Studies have shown that for several vaccines, such as live attenuated, toxoid and conjugated vaccines, high maternal antibody titers inhibit the infant's humoral immune response after infant vaccination. However, it is not clear whether this decreased antibody titer has any clinical impact on the infant's protection, as the cellular immune responses are often equally important in providing disease protection and may therefore compensate for diminished antibody levels. Reports describing the effect of maternal antibodies on the cellular immune response after infant vaccination are scarce, probably because such studies are expensive, labor intensive and utilize poorly standardized laboratory techniques. Therefore, this review aims to shed light on what is currently known about the cellular immune responses after infant vaccination in the presence of high (maternal) antibody titers both in animal and human studies. Overall, the findings suggest that maternally derived antibodies do not interfere with the cellular immune responses after infant vaccination. However, more research in humans is clearly needed, as most data originate from animal studies.
