Immunosuppressive therapy protects the transplanted organ but predisposes the recipient to chronic infections and malignancies. Transplant patients are at risk of cervical intraepithelial neoplasia (CIN) and cervical cancer resulting from an impaired immune response in the case of primary infection or of reactivation of a latent infection with human papillomavirus of high oncogenic potential (HR-HPV).

To determine and compare maternal, neonatal and graft outcomes in pregnant women after kidney or liver transplantation, who had delivered from 1 January 2005 to 1 February 2010. A retrospective, single-center study provided in Warsaw, Poland. Complete data were collected in 38 deliveries in 37 women. Preexisting hypertension was present in 15 of 19 (79%) pregnant kidney recipients and in 2 of 19 (10.5%) women after liver transplantation (p < 0.000). The incidence of preeclampsia was also more often in pregnant kidney recipients (p = 0.04). Mean gestational age at labor was lower in the kidney group (34.9 ± 3.56 vs. 37.5 ± 1.62, p = 0.000). A similar relation was observed in the frequency of preterm deliveries before 37 weeks of gestation (42% vs. 11%, respectively, p = 0.02) and neonates small for gestational age (47% vs. 11%, respectively, p = 0.008). Cesarean sections were performed in approximately 79% (15/19) and 95% (18/19) liver and kidney posttransplant pregnancies, respectively. Four of 38 infants presented structural malformations. Pregnancies after kidney transplantation are complicated with a higher prevalence of prematurity and worse neonatal prognosis, which depends mainly on the underlying condition.

Female kidney graft recipients are regarded as a group at risk of cervical cancer development. The objective of this study was to assess the prevalence of cervical high-risk human papilloma virus (HR-HPV) infection and cervical intraepithelial neoplasia (CIN) in female kidney graft recipients in comparison to healthy controls. We assessed the prevalence of HR-HPV and CIN in 60 female kidney graft recipients of reproductive age in outpatient care of the First Department of Obstetrics and Gynecology, Medical University of Warsaw. The control group consisted of 60 healthy women. Cervical swabs were analyzed with use of Amplicor HPV Roche Molecular Systems test, detecting DNA of 13 types of high-risk HPV: 6, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. HR-HPV was detected in 11/60 kidney recipients and 15/60 healthy women (p=0.37). There was no correlation between HR-HPV presence and immunosuppressive regimen, underlying disease, graft function, or time interval from transplantation. In both groups, higher prevalence of HR-HPV was observed in females with ≥2 lifetime sexual partners. Abnormal Pap test results in 2 kidney recipients (2 cases of HSIL) and 2 healthy women (LSIL and HSIL) required colposcopy-guided cervical biopsy, which in all cases revealed CIN2+. Female kidney graft recipients seem to be equally exposed to cervical infection with HPV of high oncogenic potential as the healthy population.

The rate of post-transplant mothers who breastfeed while on immunosuppression is progressively increasing. Data on breastfeeding while on cyclosporine-based regimens are limited. Therefore, we assessed the amount of cyclosporine and its metabolites that might be ingested by a breastfed infant by measuring the concentration of cyclosporine and its metabolites in the colostrum of seven post-transplant mothers. The mean concentration of cyclosporine in the colostrum was 22.40 ± 9.43 mcg/L, and the estimated mean daily dose of the drug was 1049.22 ± 397.41 ng/kg/24 h. Only three metabolites (AM1, DHCsA, and THCsA) had mean colostrum amounts comparable to or higher than cyclosporine itself, with the daily doses being 468.51 ± 80.37, 2757.79 ± 1926.11, and 1044.76 ± 948.56 ng/kg/24 h, respectively. Our results indicate a low transfer of cyclosporine and its metabolites into the colostrum in the first two days postpartum and confirm the emerging change to the policy on breastfeeding among post-transplant mothers. A full assessment of the safety of immunosuppressant exposure via breastmilk will require further studies with long-term follow-ups of breastfed children.

The aim was to investigate, among pregnant women, (1) the use of food supplements and (2) the awareness of food supplement recommendations and beliefs about food supplement use in four European countries: Finland, Italy, Poland, and the United Kingdom. The participants (n = 1804) completed an online questionnaire with predefined statements. Daily intakes of vitamins and minerals were calculated using uploaded pictures or weblinks of the supplement packages. Country differences were assessed. Most participants (91%) used at least one food supplement during pregnancy. A prenatal multivitamin was the most commonly used supplement type (84% of the users), and 75% of the participants thought consumption of multivitamin is recommended. Of the participants, 81% knew that folic acid is recommended during pregnancy while 58% knew the recommendation for vitamin D. In 19% of the supplement users, the daily safe upper intake limit of at least one nutrient was exceeded. Nevertheless, most participants agreed that they knew which supplements (91%) and doses of supplements (87%) needed to be used during pregnancy. To conclude, the majority of the participants used food supplements, but lower proportions knew and adhered to the recommended intakes. Between-country differences were observed in the use and knowledge of and beliefs regarding supplements. The results suggest a need for assessment and monitoring of supplement use in antenatal care to ensure appropriate use.
