Unwanted Pregnancy Among Kidney Transplant Recipients in Iran

Family Planning and Assessment of the Frequency of Exposure to Drugs Contraindicated in Pregnancies After Kidney or Liver Transplantation: A Retrospective Cross-Sectional Study

BACKGROUND

A successful organ transplant restores gonadal function in the first months after surgery, which leads to the normalization of menstrual cycles and increases the chance of pregnancy. Recipients of organ transplants should effectively prevent pregnancy for a minimum of 1 year and optimally up to 2 years after surgery. This study aimed to evaluate the incidence of unplanned pregnancies in female organ transplant recipients METHODS: A cross-sectional, single-center survey study of 46 pregnant organ recipients who were hospitalized at the Department of Obstetrics and Gynaecology.

RESULTS

In the post-transplant period, we recorded 46 patients, including 27 kidney recipients (59%) and 19 liver recipients (41%). Forty-nine respondents reported 66 pregnancies, of which 52 ended in live births (79%). Twenty of the pregnancies were not planned. In that group, 16 pregnancies ended in labor, 2 in miscarriage, and 2 in termination. In 10 of the unplanned pregnancies, the women were treated with potentially teratogenic drugs in the first trimester. The duration of the pregnancy was shorter in the group of women who had not planned their pregnancies and had conceived during potentially teratogenic therapy (30.66 ± 3.61 weeks) than in women who had planned their pregnancies (34.95 ± 4 weeks, P < .0215).

CONCLUSION

Women after organ transplantation are at high risk for pregnancy complications. Therefore, conception planning is an important element of post-transplant care, especially because the percentage of unplanned pregnancies in this group remains high despite the use of potentially teratogenic drugs.

Overview of pregnancy in solid-organ transplantation

PURPOSE OF REVIEW

Pregnancy in solid organ transplantation (SOT) is a very complex part of transplant medicine wherein there is scarce information available in the literature. Solid organ transplant recipients often have comorbidities, such as hypertension and diabetes, which add additional risk to a pregnancy.

RECENT FINDINGS

We present this review article on the various aspects of different types of immunosuppressant medications used in pregnancy with added inputs on contraception and fertility after transplant. We described the antepartum and postpartum considerations and discussed the adverse effects of the immunosuppressive medications. Maternal and fetal complications of each SOT have been also discussed in this article.

SUMMARY

This article will serve as the primary review articles for the use of immunosuppressive medications during pregnancy with consideration during pregnancy after SOT.

Contraceptive use among women with kidney transplants in the United States

Background

Kidney transplant improves reproductive function in women with end-stage kidney disease. Little is known about contraceptive use in women with history of kidney transplants.

Methods

Using data from the United States Renal Data System, we evaluated for each calendar year women with kidney transplantation between 1/1/2005 and 12/31/2013 who were aged 15–44 years with Medicare as the primary payer and linked data from the United Network for Organ Sharing, for up to three entire years after the date of transplantation. We determined rates of contraceptive use and used multivariable logistic regression to identify factors associated with contraceptive use.

Results

The study cohort included 13,150 women and represented 26,624 person-years. The rate of contraceptive use was 9.5%. Compared to women aged 15–24 years, contraceptive use was lower in women aged 30–34 years (OR 0.67; CI 0.58–0.78), 35–39 years (OR 0.36; CI 0.31–0.43), and 40–44 years (OR 0.23; CI 0.19–0.28). Compared to white women, contraceptive use was higher both in black women (OR 1.26; CI 1.10–1.43) and Native American women (OR 1.52; CI 1.02–2.26). Women had lower rates of contraceptive use in the second-year post-transplant (OR 0.87; CI 0.79–0.94) and the third-year post-transplant (OR0.69; CI 0.62–0.76) than in the first-year post-transplant. Women with a history of diabetes had a lower likelihood of contraceptive use (OR 0.80; CI 0.65–0.99).

Conclusion

Among women with kidney transplants, contraceptive use remains low at 9.5%. Factors associated with a higher likelihood of contraceptive use include younger age and black and Native American race/ethnicity; and second- and third-year post-transplant. The history of diabetes is associated with a lower likelihood of contraceptive use. The study highlights the need of increasing awareness for safe and effective contraceptive use in women with kidney transplants.

Prevalence of unwanted pregnancy in Iranian women: a systematic review and meta-analysis

BACKGROUND

Unwanted pregnancies are considered as one of the most important public health risks. Regarding the importance of the unwanted pregnancy in the country and helping health policy-makers obtain more accurate information on this issue, this study aims to provide a systematic review and meta-analytical on the prevalence of unwanted pregnancies in Iran.

METHODS

The present study was carried out using meta-analysis. Articles related to the topic were obtained through SID, Magiran, Scopus, PubMed, and ScienceDirect and Google Scholar databases from 2001 to 2017, Articles written based on cross-sectional studies were included in the study and other overviews, case-control, cohort, and interventional studies were excluded from the list of articles. Heterogeneity of studies was investigated using I2 index and data analysis was performed in Comprehensive Meta-Analysis software (Version 3).

RESULTS

In 23 articles, the prevalence of unwanted pregnancy in Iranian women was 27.9% (95%CI: 24-32.1%). The meta-regression analysis was used in two sample sizes and years of study. It was reported that as the sample size and Years increases, the prevalence of the unwanted pregnancy decrease, this difference was also statistically significant (P = 0.000).

CONCLUSION

Considering that the prevalence of unwanted pregnancy is high in Iran, it is necessary that health policy makers take effective measures to enhance the awareness of couples and public information about the risks of the unwanted pregnancy.

Unintended pregnancies and family planning among women after kidney or liver transplantation

Background: To evaluate the incidence of unplanned pregnancies in female organ transplant recipients.Methods: In a single-center cross-sectional study 252 women aged 18-45 years who underwent kidney or liver transplantation were asked to fill in a survey form.Results: 217 (86%) women were enrolled in the study. Fifty-three percent of women declared 181 pregnancies, of which 30% (54/181) were unplanned. Women more frequently consulted their conception with a doctor post-transplantation (74 versus 88%, p = .064). The number of unplanned pregnancies decreased post-transplantation (34 versus 20%, p = .051). The mean time elapsed from an organ transplant to unintended conception was 27.0 ± 12.5 (3.0-63.0) months. Women with longer (>24 months) rather than shorter (≤24 months) time elapsed from the transplant became pregnant less frequently (38 versus 15%, p = .060). In 70% (38/54) of unplanned pregnancies women did not use any birth control. All cases of conceptions within the post-transplant year were unintentional. Every third woman, who underwent the transplantation up to 1 year before the study enrolment, was unaware of the necessity to prevent the pregnancy.Conclusions: Although unwanted pregnancies occur more frequently in the early post-transplant period, it seems that women after kidney or liver transplantation seem to plan their pregnancies more carefully.

Pregnancy management of women with kidney transplantation

Women with renal disease, besides many dysfunctions, face increasing infertility and high-risk pregnancy due to uremia and changes of the hormonal functions. After renal transplantation, sexual dysfunction improves, providing the possibility of successful pregnancy for women of childbearing age. However, kidney transplanted patients are high-risk pregnant patients with increased maternal and fetal risks, and the graft also may be compromised during pregnancy; most studies report on several successive deliveries due to multidisciplinary team management. In clinical practice, the graft is rarely affected during the period of gestation. Fetal development disorders are also rare although preterm delivery and intrauterine growth retardation are common. For now, several studies and clinical investigations proved that, under multidisciplinary control, kidney transplanted female patients are also possible to have safe pregnancy and successful delivery. There are conflicting data in the literature about the prevention of complications and the timing of pregnancy. Herein, we would like to present some experience of our centre. A total of 847 kidney transplantations have been performed between June 1993 and December 2013 with 163 childbearing aged females (18-45 years) in our center. We report on three kidney transplanted patients who have given birth to healthy newborns. In our practice, severe complications have not been observed.

Reproductive health care after transplantation

Contraception, cervical cancer screening, human papillomavirus (HPV) vaccination, sexually transmitted infection (STI) screening, and menstrual disorders are issues that need to be addressed in all reproductive-aged women, including those with a history of solid organ transplantation. There are specific considerations that may alter routine care in this population. Due to teratogenic immunosuppressive medications, highly effective contraception is important to planning or appropriately timing pregnancy. Estrogen-containing methods (pill, patch, and ring) may be contraindicated. Immunosuppression is also a consideration when screening for and treating STIs including precancerous conditions of the cervix. This chapter will provide a framework to address the specific gynecologic needs of women with a history of solid organ transplantation.

Contraceptive awareness and birth control selection in female kidney and liver transplant recipients

OBJECTIVE(S)

Interest has increased regarding the issue of contraception in transplant recipients. The purpose of this study was to assess birth control selection and the role of contraceptive counseling sessions in female kidney transplant (KT) and liver transplant (LT) recipients.

STUDY DESIGN

A cross-sectional single-center survey study of 217 female organ recipients (KT, 137 and LT, 80), aged 18-45 years, met the study criteria. Patients were asked 43 questions regarding their pre- and posttransplantation use of contraceptive methods, birth control awareness, contraception counseling and the factors determining the selection of effective contraception (hormonal contraception, intrauterine devices and female sterilization).

RESULTS

Thirty-three percent (5/15) of patients who had undergone the transplantation within 1 year prior to study inclusion were unaware of the necessity to use contraception. Both of the groups studied did not differ significantly in terms of the rates of pre- and posttransplantation consultations on effective contraception (KT: 26% vs. 34%; p=0.153 and LT 38% vs. 35%; p=0.729). Effective posttransplantation contraception was used by one in three patients, as indicated by posttransplantation consultations (KT: 30% vs. LT: 29%; p=0.910). The following factors affected the posttransplantation use of effective contraception: the presence of posttransplantation counseling on effective contraception [odds ratio (OR): 6.67; 95% confidence interval (CI): 2.12-20.1] and infrequent sexual activity prior to transplantation (OR: 0.56; 95% CI: 0.35-0.89).

CONCLUSION(S)

The selection of effective contraception in KT and LT recipients remain suboptimal. Despite the low numbers of women who received contraceptive counseling in this study, consultation was nonetheless associated with choosing an effective method of contraception.

IMPLICATION

Current literature and data regarding contraception among female organ transplant recipients remain limited and are predominantly limited to a single population. The purpose of the study was to assess the level of satisfaction and the reasons underlying birth control selection in female kidney and LT recipients.

Prevalence of unwanted pregnancy in Iran: a systematic review and meta-analysis

INTRODUCTION

Different studies show that a considerable number of pregnancies are unwanted and can have side effects on mothers'' children's and finally society's health. Accordingly, this meta-analysis study has been carried out to estimate a relatively accurate level of unwanted pregnancies in Iran.

METHODS

Present studies and published documents were retrieved from Persian and English electronic databases. To increase sensitivity and to select more studies, the reference list of the published studies was checked. After studying the titles and texts of documents, repeated and irrelevant ones were excluded. Data was analyzed using STATA V.11.

RESULTS

Forty-nine qualified papers were selected with a 43,061 sample size. The meta-analysis of unwanted pregnancy prevalence in Iran equals 30.6% (CI = 28.1-33.1). Also' according to the present meta-analysis' the most common contraceptive methods used by couples prior to unwanted pregnancies are as follows: pills 27.1%' withdrawal 38.6%' IUD 11.4%' injection contraceptives 2.8%' vasectomy 0.28% and no method 24.5%.

DISCUSSION AND CONCLUSION

The results of meta-analysis showed that about one-third of pregnancies in Iran are unwanted and a high percent of them are among women who had used contraceptives. Therefore' it is necessary to adopt more appropriate policies on the following: education, proper pregnancy age, using contraceptive methods, men's role in family planning programs and quality promotion in family planning services.

Pregnancy after transplantation

The National Transplantation Pregnancy Registry (NTPR) was established in 1991 to study the outcomes of pregnancies in female transplant recipients and pregnancies fathered by male transplant recipients. Data from the NTPR have helped to endorse the reassurances from publications of smaller experiences that successful pregnancies are possible in the transplant population. In our last review for this journal (2000), we noted that important future issues would include the reassessment of prepregnancy guidelines, gestational and organ-specific problems, the role of new immunosuppressive drugs, and the long-term effects of pregnancy on both graft and child. Data collected by the NTPR over the last 7 years have addressed these issues, thus providing additional information for health care providers of transplant recipients of childbearing age. There has been some refinement of prepregnancy guidelines, but there is a need for additional data collection so that organ-specific outcomes and risks can further be identified. To date, the outcomes of the children followed have been encouraging, and specific remote effects have not been identified, but continued surveillance is still vital. Of special concern are the new immunosuppressive drugs, specifically for mycophenolate mofetil (CellCept, Roche Laboratories Inc., Nutley, New Jersey), where data reported to the NTPR and through postmarketing surveillance have shown an increased incidence of nonviable outcomes and a specific pattern and increased incidence of malformation in the newborn, which has resulted in a pregnancy category change. Newer information points to an increased need for vigilance among centers and continued monitoring of pregnancy outcomes in this population. As the first reported pregnancy after transplantation occurred in a kidney recipient 50 years ago, in March 1958, this review also highlights the first reported pregnancies in other solid organ recipients.
