Delivery Method in Patients After Liver or Kidney Transplantation.

Pregnancy following renal or liver transplant is safe for the mother, fetus, and allograft if standard practice guidelines are strictly followed. Cesarean delivery is often required for the safety of the mother and child. The aim of this paper was the evaluation of delivery method in patients after liver (G1) and kidney transplantation (G2) in comparison with the population of healthy pregnant women (G0). MATERIALS: Retrospective analysis included 51 (G1) and 59 (G2) women who delivered between 2000 and 2016. Control group (G0) consisted of 170 nontransplanted patients, who delivered between 2014 and 2016. The results were compared using nonparametric and parametric tests (Fisher exact test, t test). The SAS 9.2 was used for the analysis. RESULTS: The rate of cesarean delivery was high in all pregnancies following kidney (G1 = 80.4%) or liver transplantation (G2 = 67.8%) compared with control group (G0 = 44.1%; P < .05). The most common indication for cesarean delivery in G1 was gestational hypertension/preeclampsia (n = 18; 43.9%), threatening intrauterine asphyxia (n = 12; 29.3%), and failure to progress (n = 2; 4.9%). The most common indications for cesarean delivery in G2 were threatening intrauterine asphyxia (n = 14; 35%), failure to progress (n = 9; 22.5%), and gestational hypertension/preeclampsia (n = 2; 5%). CONCLUSION: Cesarean delivery in patients after kidney or liver transplantation is performed mainly for obstetric reasons. The reported incidence of cesarean delivery in pregnancy following transplant is high, reflecting the high degree of clinical caution exercised in these patients.

Prevalence of Cervical Infection With Human Papillomavirus of High Oncogenic Potential in Immunosuppressed Women on Renal Replacement Therapy With and Without Mammalian Target of Rapamycin Inhibitors.

BACKGROUND: Chronic immunosuppression constitutes a risk factor of human papillomavirus (HPV) related cervical cancer development. Maintenance immunosuppression with mammalian target of rapamycin (mTOR) inhibitors is associated with decreased incidence of de novo malignancies in kidney graft recipients. Recently published data suggest that mTOR inhibitors interfere with viral replication. The aim of the study was to assess if there is a difference in prevalence of HPV cervical infection in women on immunosuppressive regimens with or without mTOR inhibitors. MATERIAL AND METHODS: Cervical swabs taken from 64 immunosuppressed women on renal replacement therapy were analyzed for the presence of high-risk (HR) HPV DNA by means of an Amplicor HPV test and assessed taking into account the recorded data on mTOR inhibitor use. RESULTS: The testing revealed the presence of HR HPV DNA in none of the women that were treated with mTOR inhibitors and in 21.4% of patients that were administered immunosuppressive regimens without mTOR inhibitors (P = .08). Interestingly, 32% of women from the mTOR(-) group in contrast to 12.5% in the mTOR(+) group declared having had more than 2 lifetime sexual partners. CONCLUSIONS: Our results suggest that mTOR inhibitors might constitute a promising therapy modification in women at risk of HPV cervical malignancy development, but the effectiveness of such strategy requires further studies.

In Vitro Fertilization and Pregnancy Outcomes Among Patients After Kidney Transplantation: Case Series and Single-Center Experience.

INTRODUCTION: Kidney transplantation (KTx) is the treatment of choice in patients with end-stage renal failure. Among various medical issues in female graft recipients, the need for maternity can become an overriding one. Gonadal dysfunction usually resolves within 6 months after transplantation; however, the prevalence of infertility is similar to this in the general population. MATERIALS AND METHODS: This case series describes the experience in infertility treatment and following perinatal care among KTx women who underwent successful in vitro fertilization (IVF). We followed three patients who previously received KTx and underwent IVF between 2014 and 2015. The 34-year-old (patient A) and 39-year-old (patient B) women received single KTx, and the 31-year-old (patient C) woman had received three previous transplantations. Patients A and C were diagnosed with primary tubal factor infertility, while patient B suffered from secondary idiopathic infertility. The stimulation protocols had no influence on their general condition nor graft function. Viable singleton pregnancies were confirmed in all cases. All newborns were born preterm, via cesarean section, as a consequence of severe preeclampsia. Patients A and C gave birth at 34th week of gestation (WG) (A: 1810 g and C: 2295 g), while patient B gave birth at 36th WG (2655 g). Other pregnancy complications were intrauterine growth restriction (patient A) and gestational diabetes mellitus (patient B). Although mild graft dysfunction was observed prior to delivery, all clinical measures and hypertension resolved during the puerperium. CONCLUSIONS: In these cases, pregnancy after KTx did not implicate persistent graft dysfunction. Regardless of the method of conception, pregnancy following KTx is associated with an increased incidence of complications, therefore it requires a multidisciplinary approach. IVF itself seems to be a safe procedure in KTx recipients if the pregnancy is advisable.

Should We Be Concerned About Asymptomatic Adnexal Masses in Female Kidney and Liver Graft Recipients?

BACKGROUND: Pathological changes of uterine adnexa are frequently encountered in patients after solid-organ transplantation. The aim of the study was to evaluate the incidence of malignancies among recipients operated with the diagnosis of adnexal tumor with or without clinical symptoms. METHODS: We retrospectively analyzed data from 146 solid-organ recipients who underwent surgery in the First Department of Obstetrics and Gynecology, Medical University of Warsaw, in the years 2000 to 2014. Among them, we identified 80 patients of mean age 40.9 ± 11.1 years with suspected adnexal tumor. Data on symptoms reported by patients were compared with the results of histopathological examination after surgical treatment. RESULTS: Kidney recipients were 76.2% of the group studied (including 5 women after kidney and pancreas transplantation); the remaining 23.75% of patients were liver recipients (including 1 kidney and liver). The majority of patients (71.25%) reported no clinical symptoms. The remaining 28.75% of patients had clinical complaints, with the most common symptom being abdominal pain (in 60% of patients). Analysis of the results of histopathological examination revealed that in both groups, the most often encountered pathological findings were serous cystadenoma (33.3% and 47% of patients, respectively), endometrial cysts (24.6% and 21.7%, respectively), and functional cysts (22.8% and 17.3%, respectively). None of the asymptomatic patients were diagnosed as malignant, whereas 2 cases (both ovarian and fallopian tube cancer) were diagnosed among women who reported clinical symptoms. CONCLUSIONS: Observations of patients after organ transplantation indicate a recurring nature of adnexal changes, resulting in qualification for surgical treatment. The survey results suggest that solid-organ recipients with pathology in the uterine adnexa, with non-suspicious ultrasound image and not reporting clinical symptoms, could safely be subjected to clinical observation providing strict supervision.

Hypertension in Pregnant Renal and Liver Transplant Recipients.

BACKGROUND: Pregnancies in transplant recipients involve risks for both grafts and the fetus, and need to be carefully managed. Hypertension is the most frequent complications in pregnant transplant recipients, especially in renal transplant recipients. Strict control of blood pressure is essential for a favorable obstetric outcome and long-term graft survival. The aim of the study was to evaluate the influence of hypertension on obstetric outcome and graft function in pregnant renal transplant recipients (RTR) or liver transplant recipients (LTR) in comparison with healthy pregnant women. PATIENTS AND METHODS: This retrospective analysis included 46 RTR and 55 LTR who delivered between the years 2000 and 2014. The control group consisted of 187 nontransplant patients aged 20-45 years who delivered between 2010 and 2013. The analyzed group was divided into 2 subgroups: patients with hypertension and patients without hypertension. Descriptive data analysis, Fisher Exact test, unpaired Student t test, and analysis of the variance were performed. RESULTS: Hypertension prevalence among the RTR, LTR, and control group was 73.5%, 34.5%, and 4.3% respectively. In the RTR group, the mean gestational age at delivery inp patients with hypertension vs without hypertension was 36 vs 34.5 weeks (P < .05); IUGR was diagnosed in 20% vs 8.5% pregnant women (P > .05). In the TRL group, the mean gestational age at delivery in group with hypertension vs without hypertension was 37 vs 3.9 weeks (P < .05); IUGR was diagnosed in 10.5% vs 5% of pregnant women (P > .05). Hypertension in RTR patients had a negative influence on graft function (P > .05). CONCLUSION: Hypertension is common in organ recipients, and is associated with adverse pregnancy outcomes and loss of graft function.

Contraception in women after organ transplantation.

INTRODUCTION: Organ transplantation has improved the quality and length of life for many people suffering from end-stage diseases, among them women of reproductive age. Therefore, it has made pregnancy possible for those previously unable to conceive. Nevertheless, conception itself should be desired and properly timed in these specific patients to ensure the best possible perinatal outcome. OBJECTIVE: The objective of the study was to assess whether female graft recipients apply proper family planning methods and use effective contraception. METHODS: In a single-center, observational study, information was collected using a self-administered questionnaire distributed among 100 female graft recipients (post-transplant group [TG]) and 67 healthy female volunteers (control group [CG]). The survey covered data regarding present menstrual patterns, sexual activity, gynecological counseling, and contraceptive methods used. RESULTS: Female graft recipients were more sexually active after than before transplantation (87% vs 64%, P = .0001) and equally active as controls. Sexually active post-transplantation patients used contraception less frequently than sexually active controls (51.72% vs 82.76%, P < .0001). Condoms were the most frequently used method in TG, and oral contraception in CG. Oral contraception was used more rarely by counseled graft recipients than by counseled controls (3.9% vs 60.7%, P < .0001). After counseling, intrauterine device usage increased and oral contraception usage decreased in TG. Among women with chronic diseases, intrauterine device was used more often in TG (4% vs 0%), whereas oral contraception was used more often in CG (8.3% vs 50%, P < .0001). CONCLUSIONS: Despite the fact that post-transplantation women of reproductive age have many indications for highly effective contraception, only few of them actually use it. Contraceptive counseling has to be included as part of routine post-transplantation care by all health professionals involved in the management of female graft recipients of reproductive age.
