The contraceptive vaginal ring in women with renal and liver transplantation: analysis of preliminary results.

INTRODUCTION: Vaginal administration seems to be the best route to achieve steady and precise doses of contraceptive hormones, resulting in stable serum concentrations and low exposure. The aim of this study was to evaluate the contraceptive efficacy, cycle control, tolerability and acceptability of a contraceptive vaginal ring (NuvaRing) in renal and liver transplant recipients. MATERIAL AND METHODS: Renal or liver transplant recipients, asking for contraception, were enrolled into the study. The duration of treatment was 12 cycles, with each vaginal ring releasing an average of 120 mg etonogestrel and 15 mg ethinylestradiol daily. Study visits were scheduled at screening, in the first week following cycles 3, 6, and 12 (172 cycles). RESULTS: Among 17 females included into the study: were 9 renal (mean age, 30 +/- 7.2 years) and 8 liver transplant recipients (mean age, 32.6 +/- 6.6 years). At the onset of therapy all patients showed at least 6 months of stable graft function with no signs of allograft rejection. The mean posttransplant follow-up was 4 +/- 3.6 and 5.3 +/- 2.1 years for women with renal and hepatic transplantations respectively (P = NS). The immunosuppressive therapy was not changed for any patient. We demonstrated good cycle control: 162 cycles did not exhibit any bleeding; 7 cycles, only spotting episodes, whereas 2 cycles had 1 bleeding episode during the ring period. The estrogen-related adverse events (nausea and breast tenderness) were reported in 2 patients. One patient experienced significant bleeding related to thrombocytopenia. DISCUSSION: Nuvaring, in our preliminary findings, may be considered to be an highly effective contraceptive method for female transplant recipients that additionally regulate menstrual bleeding and seems to positively influence well-being. Vaginal administration may diminish the chance of drug interactions and therefore be safer for patients.

Pregnancy and renal transplantation: a case report of the risk of antibody induction against partner antigens.

Renal transplantation has provided women of childbearing age with increased fertility and the possibility of successful pregnancy outcomes. Approximately 14,000 births among women with transplanted organs have been reported worldwide, but pregnancy complications have been frequent: spontaneous or therapeutic abortion, preterm birth, low birth weight, and intrauterine growth restriction. Herein we have described a case of an acute rejection episode in a renal transplant recipient, occurring 6 months after successful delivery, despite the fulfillment of all European best practice guidelines criteria and the maintenance of adequate immunosuppression. Our case demonstrated that even a presumably low-risk patient can face worsening of renal function during or after pregnancy. Acute immune activation is uncommon but may occur in late-onset fashion. Despite adequate levels of maintenance immunosuppression, there is a risk of developing antibodies against the partner or the donor, causing acute renal immune damage.

Quality of life in renal transplant patients over 60 years of age.

Kidney transplantation not only drastically improves the life-expectancy of hemodialyzed patients, but it also affords psychological and social advantages with improvements in short- and long-term personal and working lives. Quality of life (QoL) is one of the parameters of psychological well-being. There is an improvement of QoL from pre- to posttransplant, but it is not to the level of healthy samples. The aim of this study was to examine QoL in older renal transplant recipients. All recipients older than age 60 were included, with a minimum follow-up of 12 months. To measure QoL, the nationally standardized ShortForm-36 (SF-36) questionnaire was administered. The SF-36 responses by our patients were compared with national age- and gender-appropriate norms, and also between genders. The enrolled population included 19 women (36.5%) and 33 men (63.5%), with a mean age of 66.8 years (range, 60-73 years). Enrolled women reported significant limitations compared to gender- and age-matched norms in social activities (42.11 vs 70.58), perception of pain (22.11 vs 59.17), and general health perception (39.58 vs 48.69). Enrolled men reported significant limitations compared to gender- and age-matched norms in social activities (46.59 vs 78.35), perception of pain (18.18 vs 73.62), psycho-physical energy (50.15 vs 67.88), and general health perception (37.33 vs 61.66). No significant differences were noted between the genders. This study clearly showed how the psychological state was not as good as the clinico-physical recovery following renal transplantation in older recipients.
