Abstract
Cystic Fibrosis (CF) is the most common autosomal recessive genetic multisystemic disease. In Germany, it affects at least 8000 people. The disease is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene leading to dysfunction of CFTR, a transmembrane chloride channel. This defect causes insufficient hydration of the airway epithelial lining fluid which leads to reduction of the mucociliary clearance.Even if highly effective, CFTR modulator therapy has been available for some years and people with CF are getting much older than before, recurrent and chronic infections of the airways as well as pulmonary exacerbations still occur. In adult CF life, Pseudomonas aeruginosa (PA) is the most relevant pathogen in colonisation and chronic infection of the lung, leading to further loss of lung function. There are many possibilities to treat PA-infection.This is a S3-clinical guideline which implements a definition for chronic PA-infection and demonstrates evidence-based diagnostic methods and medical treatment in order to give guidance for individual treatment options.

Abstract
Cystic fibrosis is a monogenic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) protein, which transports chloride ions in secretory organs. Modulator therapies are small molecules that correct CFTR dysfunction and can lead to a wide range of benefits for both pulmonary and extrapulmonary complications of cystic fibrosis. With advancements in airway, antimicrobial and nutritional therapies and now introduction of modulator therapies, most people living with cystic fibrosis in Australia are now adults. For adults with cystic fibrosis, endocrine manifestations such as cystic fibrosis-related diabetes, metabolic bone disease, and reproductive health are becoming increasingly important, and emerging evidence on the endocrine effects of CFTR modulator therapies is promising and is shifting paradigms in our understanding and management of these conditions. The management of cystic fibrosis-related diabetes will likely need to pivot for high responders to modulator therapy with dietary adaptions and potential use of medications traditionally reserved for adults with type 2 diabetes, but evidence to support changing clinical care needs is currently lacking. Increased attention to diabetes-related complications screening will also be required. Increased exercise capacity due to improved lung function, nutrition and potentially direct modulator effect may have a positive impact on cystic fibrosis-related bone disease, but supporting evidence to date is limited. Fertility can improve in women with cystic fibrosis taking modulator therapy. This has important implications for pregnancy and lactation, but evidence is lacking to guide pre-conception and antenatal management. Provision of multidisciplinary clinical care remains ever-important to ensure the emergence of endocrine and metabolic complications are optimised in adults with cystic fibrosis.

Abstract
The introduction of mutation-specific therapy led to a revolution in cystic fibrosis (CF) care. These advances in CF therapies have changed the disease profile from a severe incurable disease with limited survival to a treatable disease with improved quality of life and survival into adulthood. CF patients are now able to plan their future, including marriage and parenthood. Side by side with the optimism, new issues and concerns are arising, including fertility and preparation for pregnancy, maternal and fetal care during pregnancy, and post-partum care. While cystic fibrosis transmembrane regulator (CFTR) modulators show promising results for improving CF lung disease, data on their safety in pregnancy are still limited. We performed a literature review on pregnancy in CF from the past, with the first described pregnancy in 1960, through the current fascinating changes in the era of CFTR modulators, to ongoing studies and future directions. Current advances in knowledge give hope for improved outcomes of pregnancy, towards the best possible prognosis for the mother and for the baby.

Abstract
BACKGROUND People with cystic fibrosis (CF) are living longer and healthier lives as a result of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies, and are pursuing pregnancy. As the number of pregnancies in CF continue to increase, clinician attitudes and practices regarding care of pregnant people with CF remain largely unknown. OBJECTIVE To evaluate the current attitudes and practices of CF clinicians regarding pregnancy planning and care in CF. METHODS We conducted a national survey investigating practice patterns related to pregnancy care in CF. We used descriptive statistics to summarize responses and paired t-tests to compare population means. RESULTS A total of 93 clinicians completed the survey. Eighty-six percent of respondents believed family planning and pregnancy discussions should start before the age of 21 years, of which 67% believed these discussions should occur prior to age 18 years. Our results demonstrate variability in CF clinician comfort and management of various aspects of pregnancy care in CF including 1) potential complications of pregnancy 2) continuation of chronic CF therapies 3) continuation of CFTR modulators during pregnancy and lactation, and 4) approach to treatment of pulmonary exacerbation during pregnancy. CONCLUSIONS As more people with CF pursue pregnancy in the era of CFTR modulators, CF providers should be initiating discussions surrounding pregnancy early and often. Establishing best practices in the management of pregnancy in CF, expanding peri‑pregnancy expertise within the CF community, and future studies investigating the maternal-fetal effects of CF therapies are needed.

Abstract
Background We present the first case to our knowledge of a spontaneous twin pregnancy in a 16-year-old Caucasian patient with cystic fibrosis and systemic lupus erythematosus. Cystic fibrosis is one of the most common autosomal recessive genetic disorders and primarily affects the respiratory and digestive systems. Systemic lupus erythematosus is a chronic inflammatory disease of unknown cause that affects nearly every organ. Patients with cystic fibrosis or systemic lupus erythematosus are progressively having longer life expectancy and better quality of life, which has led a greater number of female patients reporting the desire to become mothers. Case presentation We present a case of a Caucasian 16-year-old pregnant with twins being treated for both cystic fibrosis and systemic lupus erythematosus. She has two CFTR mutations: p.F508del and 1812_1G>A. In the second trimester, she was admitted for possible preterm labor, which was successfully stopped. The patient’s nutritional status worsened, and she had a pulmonary exacerbation as well as a flare of systemic lupus erythematosus. At the 28th gestational week, she presented with a massive hemoptysis episode. The cesarean delivery had no complications, and there were no serious immediate postpartum complications. Discussion and conclusions While adolescent pregnancies in and of themselves are considered high risk for both the young mothers and their children, they are further complicated when the mother has two chronic diseases and a twin pregnancy. We achieved positive results using a multidisciplinary approach; however, the risks involved were so high that major efforts are to be taken by our medical community to prevent unplanned pregnancies in all patients with cystic fibrosis, especially when a serious comorbidity like the one in this case is present.

Abstract
As people with cystic fibrosis (CF) live longer and healthier lives, increasing numbers are considering the full range of reproductive options for their futures, including parenthood, pregnancy, or pregnancy prevention. As the face of CF changes, the CF care model must adapt to meet the reproductive health needs of both parents and nonparents with CF. This article summarizes the reproductive goals and family-building concerns faced by people with CF, including fertility, pregnancy, and alternative paths to parenthood, the impact of parenthood on mental and physical health, and important future research.

Abstract
Women with cystic fibrosis (CF) face several unaddressed concerns related to their health. These areas of concern include explanations and guidance on a sex disparity in outcomes, timing of puberty, effects of contraception, prevalence of infertility and impact of pregnancy, and prevention of urinary incontinence and osteoporosis. These understudied topics leave women with numerous unanswered questions about how to manage sexual and reproductive health in the setting of CF. Because people with CF are living longer and healthier lives, there is an increasing awareness of these important aspects of care and multiple ongoing studies to address these understudied topics.

Abstract
Cystic fibrosis (CF) was historically a disease largely afflicting children. Due to therapeutic advancements, there are now more adults with CF than children. In the past decade, medications including Cystic Fibrosis Transmembrane conductance Regulator (CFTR) modulators became available that treat the underlying cause of CF and are dramatically improving lung function as well as quality and quantity of life for people with CF. As a result, more women with CF are becoming pregnant. We gathered a panel of experts in CF care, family planning, high risk obstetrics, nutrition, genetics and women with CF to review current literature on pregnancies and to provide care recommendations for this unique population.

Abstract
People with Cystic fibrosis (pwCF) have experienced increased survival and wellbeing in recent decades, such that more than half of those living with CF are adults. Consequently, sexual and reproductive health is increasingly important for pwCF as many are considering parenthood. Most men and some women with CF (wwCF) will have reduced fertility, which in both sexes is multifactorial. However, unplanned pregnancies in women are not rare, and contraception and its interaction with CF complications need to be addressed by the CF team. Reduced fertility may be overcome in most pwCF through use of assisted reproductive technologies; however, the risk of having offspring with CF must be considered. Most wwCF will have normal pregnancies, but premature birth is common especially in the setting of reduced lung function and CF related diabetes (CFRD); optimization of treatment is recommended during pregnancy planning. Parenting imposes an increased burden on pwCF, with the challenges of caring for the newborn, postpartum physiologic changes and maintaining CF treatments. Most drugs used to treat CF are considered safe in pregnancy and lactation, but exceptions need to be acknowledged, including the limited data regarding safety of CF transmembrane conductance regulator (CFTR) modulators during conception, pregnancy, and lactation. As most pwCF are eligible for highly effective CFTR modulators, fertility, contraception, and pregnancy in people with CF is changing. Prospective studies regarding these issues in people treated with CFTR modulators are paramount to provide evidence-based guidance for management in the current era of CF care.

Abstract
Cystic fibrosis (CF) is an autosomal recessive genetic disorder impacting approximately 80,000 people of all races and ethnicities world-wide. CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene which encodes a protein of the same name. Protein dysfunction results in abnormal chloride and bicarbonate transport in mucus membranes, including those in the respiratory, gastrointestinal and reproductive tracts. Abnormal anion transport causes viscous secretions at the site of involvement. The majority of people with CF succumb to respiratory failure following recurrent cycles of infection and inflammation in the airways. Historically, providers treated the signs and symptoms of CF, but since 2012, have been able to impact the basic defect for the subset of people with CF who have mutations that respond to the new class of drugs, CFTR protein modulators. With the improved health and longevity afforded by CFTR modulators, more women are interested in parenthood and are becoming pregnant. Furthermore, this class of drugs likely increases fertility in women with CF. However, the safety of CFTR modulators in pregnancy and lactation is only beginning to be established. We summarize available data on the impact of CFTR modulators on fertility, pregnancy and lactation in women with CF.

Abstract
PURPOSE OF REVIEW With improving life expectancy and quality of life, sexual and reproductive health (SRH) has become an increasingly important aspect of patient-centered cystic fibrosis care. This review aims to describe advances in cystic fibrosis-related SRH and highlight optimal practices. RECENT FINDINGS Recent publications suggest that people with cystic fibrosis follow a similar trajectory of sexual development and activity as their noncystic fibrosis peers, although contraception use is lower. Although fertility is reduced in patients with cystic fibrosis, improved survival and assisted reproductive technologies have led to an increasing pursuit and incidence of pregnancy. Cystic fibrosis transmembrane regulator modulators that correct the underlying cystic fibrosis defect might improve fertility and thus far appear safe in pregnancy, though data are limited.Despite medical knowledge of SRH in cystic fibrosis, patients continue to report they lack sufficient education about these aspects of their healthcare, and cystic fibrosis multidisciplinary teams are ill prepared to counsel their patients. SUMMARY Understanding of the effects of cystic fibrosis on SRH continues to improve, although many questions remain regarding optimal care from the choice of contraception to the safety of cystic fibrosis-specific medications in pregnancy. Further development of cystic fibrosis-informed interdisciplinary specialist networks and a wider framework of practice would both enhance health outcomes and better support patients.

Abstract
BACKGROUND With the improved health afforded by cystic fibrosis transmembrane conductance regulator (CFTR) modulators, pregnancy rates are increasing in women with CF. In animal reproductive models, the three components of elexacaftor-tezacaftor-ivacaftor (ETI) did not cause teratogenicity at normal human doses. Although the limited human data available in the literature for previously approved modulators did not suggest cause for concern, there is currently no data in the literature regarding use of ETI in pregnant women. Thus, the decision to continue therapy during pregnancy (with the associated unknown fetal impact) versus discontinuing therapy (with the known risk of maternal health decline) is challenging. METHODS CF Center staff completed an anonymous questionnaire regarding pregnancy and infant outcomes for women who used ETI during pregnancy and/or lactation. RESULTS Of 45 ETI-exposed pregnancies reported to date, complications in 2 mothers and in 3 infants (2 born to mothers with poorly controlled diabetes) were rated by clinicians as unknown (possible) or suspected relatedness to ETI use. Two women terminated unplanned pregnancies. Miscarriage rates were consistent with that known in the general U.S. POPULATION Five of the six women who discontinued ETI out of concern for unknown fetal risk restarted because of clinical deterioration. No infant cataracts were reported though only two infants were formally evaluated. CONCLUSIONS In the context of the known increased rate of complications in women with CF and their infants, data from this retrospective survey is reassuring for women who choose to continue ETI during pregnancy. However, a large, multi-center prospective study is needed to assess impact of use of ETI in pregnancy.

Abstract
Women with cystic fibrosis (CF) are living longer and healthier lives, and opportunities for childbearing are increasingly promising. However, this population can also face sexual and reproductive health concerns, including menstrual irregularities, unplanned pregnancies, infertility and pregnancy complications. Additionally, more women are entering menopause and are at risk for the consequences of estrogen deficiency. The exact mechanisms involved in female reproductive health conditions in CF are not clearly understood, but are thought to include cystic fibrosis transmembrane regulator (CFTR)-mediated abnormalities, changes in female sex hormones, and other CF health-related factors. In the era of CFTR modulator therapy, new data are necessary to understand the impact of CFTR modulation on contraceptive effectiveness, fertility, and pregnancy outcomes to help guide future clinical care. This article reviews the current scientific knowledge of major reproductive health issues for women with CF.

Abstract
Cystic fibrosis (CF) is a life-shortening genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. These mutations lead to abnormal ion transport in mucous membranes throughout the body, including in the respiratory and gastrointestinal and reproductive tracts. Improvements in care and therapy have led to substantial increases in the quantity and quality of life for those with CF. Consequently, women with CF are increasingly interested in having families. Although pregnancy was once discouraged for women with CF, at this point, even women with moderately severe lung disease can successfully navigate pregnancy. With the recent approval of a triple combination CFTR modulator therapy that improves lung function, nutritional status, and quality of life for people with a single copy of the most common CFTR mutation, it is expected that the number of women with CF who choose to become pregnant will continue to increase. Although animal reproduction models show no alarming signals for use during pregnancy at normal human doses, there is a paucity of human safety data in pregnancy and lactation. This review summarizes what is currently known about the impact of use of CFTR modulators on fertility, pregnancy, and lactation in women with CF.

Abstract
The recent development of modulators of cystic fibrosis transmembrane conductance regulator (CFTR) has allowed the life expectancy of cystic fibrosis patients to increase substantially resulting in more women with cystic fibrosis reaching child-bearing age. This however raises the issue of whether long-term use of CFTR modulators during pregnancy and breastfeeding is safe for the fetus and newborn, especially for their developing brain. A very limited number of case reports available so far has shown that the fetus or breastfed newborn is likely to be exposed to maternally administered CFTR modulators. Potential impacts of drug exposure on the developing brain are of particular importance as the consequences might not be immediately noticeable upon birth but may manifest later in life as permanent neurobehavioral problems. In order for drugs in maternal circulation to enter the fetal brain, they must overcome the placental barrier followed by a series of brain barriers, each consisting of cellular components and physiological mechanisms such as efflux transporters. The extent of protection they offer during development will provide valuable insights into the potential entry and the effects of CFTR modulators in the developing brain. This review aims to explore the current understanding of the safety of CFTR modulators, especially ivacaftor, during pregnancy and breastfeeding, characterize the pharmacokinetics and pharmacodynamics of ivacaftor, both under normal conditions and during pregnancy, to provide context for its potential impact on the developing brain. Finally, we discuss the determinants that need to be taken into consideration when investigating the entry of drugs into the fetus and newborn.

Abstract
Cystic fibrosis (CF) is a common multi-system genetically inherited condition, predominately found in individuals of Caucasian decent. Since the identification of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene in 1989, and the subsequent improvement in understanding of CF pathophysiology, significant increases in life-expectancy have followed. Initially this was related to improvements in the management and systems of care for treating the various affected organ systems. These cornerstone treatments are still essential for CF patients born today. However, over the last decade, the major advance has been in therapies that target the resultant genetic defect: the dysfunctional CFTR protein. Small molecule agents that target this dysfunctional protein via a variety of mechanisms have led to lung function improvements, reductions in pulmonary exacerbation rates and increases in weight and quality-of-life indices. As more patients receive these agents earlier and earlier in life, it is likely that general CF care will increasingly pivot around these specific therapies, although it is also likely that effects other than those identified in the initial trials will be discovered and need to be managed. Despite great excitement for modulator therapies, they are unlikely to be suitable or available for all; whether this is due to a lack of availability for specific CFTR mutations, drug-reactions or the health economic set-up in certain countries. Nevertheless, the CF community must be applauded for its ongoing focus on research and development for this life-limiting disease. With time, personalised individualised therapy would ideally be the mainstay of CF care.

Abstract
BACKGROUND As their long-term prognosis improves, women with CF are increasingly choosing to have children, but the safety of CFTR modulators in pregnancy and breastfeeding is currently unknown. METHODS A survey was sent to lead clinicians of adult CF centres in Europe, the United Kingdom (UK), United States of America (USA), Australia and Israel requesting anonymised data on pregnancy outcomes in women using CFTR modulators before and during pregnancy and lactation. RESULTS We identified 64 pregnancies in 61 women taking IVA (n = 31), LUM/IVA (n = 26) or TEZ/IVA (n = 7), resulting in 60 live births. In 44 pregnancies, CFTR modulators were either continued throughout pregnancy or temporarily stopped and then restarted. Two maternal complications were deemed related to CFTR modulator therapy; cessation of modulator therapy resulted in clinical decline in 9 women prompting resumption of therapy during pregnancy. No modulator-related complications were reported in infants exposed in utero and/or during breastfeeding. CONCLUSIONS CFTR modulators were reported to be generally well tolerated in pregnancy and breastfeeding, with only 2 maternal complications that were deemed related to CFTR modulator therapy. Women stopping CFTR modulators in pregnancy may experience a decline in clinical status and in the cases identified in this survey, restarting therapy led to a clinical improvement. Current experience remains limited and longer-term prospective follow-up is required to exclude delayed adverse effects.

Abstract
Women with cystic fibrosis (CF) desire to become pregnant and accomplish the same life
goals as women without CF. The underlying pathology of CF and medications used to treat
this genetically transmitted disease can affect women’s reproductive potential. An
interview with Ana (pseudonym), who became pregnant twice while taking the medication
lumacaftor/ivacaftor (LUMA/IVA), was analyzed using thematic analysis. She described her
experiences related to “Fertility and Pregnancy Surrounding LUMA/IVA,” the major theme
that emerged from her narrative. While there are anecdotal reports of infants conceived by
women on LUMA/IVA and other CF precision medications, pregnancy rates and outcomes are not
systematically tracked. Education about risks and benefits of these medications should be
provided as part of comprehensive clinical care.

Abstract
Introduction: Cystic fibrosis (CF) is a complex, multi-system, genetic disease affecting over 70,000 people worldwide. The underlying defect is a mutation in the CFTR gene. Dysfunctional CFTR protein results in abnormal anion movement across epithelial membranes in affected organs. There has been a paradigm shift in CF treatment over the last decade with the advent of CFTR modulation, treatments which target this underlying genetic defect and have the potential to change the course of CF clinical disease.Areas covered: Available CFTR modulators in current clinical practice are reviewed in this article, with a direct comparison and summary of relevant pivotal clinical trials. The approval of ivacaftor and subsequent development of lumacaftor and tezacaftor dual combinations represents an exciting development in CF management in recent years.Expert opinion: Tezacaftor/ivacaftor (tez/iva) appears to have a more favorable adverse event and drug-drug interaction profile than lumacaftor/ivacaftor. Tez/iva has been approved, alongside Phe508del, for a large number of 'residual function' CFTR mutations, with some based on response to in vitro culture. Dual therapy with tez/iva has paved the way for triple CFTR modulation currently in clinical trials with an ultimate view to provide modulation therapy to the majority of CF genotypes in the future.

Abstract
Life expectancy for individuals with cystic fibrosis (CF) has significantly increased during the last few decades, and subsequently, more women with CF are considering pregnancy. A detailed understanding of the management of pregnancy, specific pulmonary treatments, and necessary medications is essential to provide specialized care for women with CF. In this article, we present the physical and psychosocial aspects of care for pregnant women with CF and describe a case involving the planned pregnancy of a nulliparous woman with CF. We suggest vigilant monitoring for adequate nutrition, weight gain, and pulmonary function throughout pregnancy as implications for nursing care.

Abstract
BACKGROUND To investigate how poor pre-gestational pulmonary function influenced pregnancy outcome and clinical status evolution in women with cystic fibrosis. METHODS Pregnancies in women without lung transplantation with a first delivery reported to the French cystic fibrosis registry between 2000 and 2012 were identified. Pregnancy outcomes and clinical trends (body mass index - BMI, and pulmonary function) over a 4-year follow-up in women with poor pre-gestational pulmonary function, defined as forced expiratory volume (FEV1) ≤ 50%, were compared to those in women with FEV1 ˃ 50%. RESULTS A total of 149 women had a first delivery and 36 (24.2%) of these had pre-gestational FEV1 ≤ 50%. There was no significant difference in age or frequency of assisted conception between the 2 groups. The rate of cesarean section was significantly higher in women with FEV1 ≤ 50% (43.7% vs. 21.1%, p = .01). The frequency of preterm birth did not differ significantly between the two groups, but median infant birthweight was significantly lower in women with FEV1 ≤ 50% (2705 g; range: 650-3700 vs. 3044 g; range: 1590-3860, p = .003). Despite significantly lower FEV1 and BMI the year before pregnancy for women with poor pulmonary function, the decline in these parameters during the study period did not differ significantly between the two groups. CONCLUSION Poor pre-gestational pulmonary function in women with cystic fibrosis was associated with a higher rate of cesarean section and a clinically significant impact on fetal growth, but was not associated with more important pulmonary and nutritional decline over the study period.

Abstract
RESEARCH QUESTION Although the impact of cystic fibrosis on male fertility is well known, very few studies have investigated its effect on female fertility. This study aimed to evaluate the fertility status of women with cystic fibrosis. DESIGN A questionnaire was sent to 220 women with cystic fibrosis. The questions concerned their desire to become a parent, achievement or not of a pregnancy, the time to become pregnant, the means of achieving pregnancy (spontaneously or with medical assistance) and the outcome of the pregnancy. Ninety-eight patients responded to the questionnaire. RESULTS Of the 46 women who sought pregnancy, 25 (54%) had at least one live birth without treatment, while 11 (24%) required infertility treatment to obtain a live birth and 10 (22%) had no delivery. The mean time-to-pregnancy was 12 months (1-180). The reasons for preferring not to become pregnant were mainly fear of the interaction between cystic fibrosis and pregnancy and of the transmission of cystic fibrosis to children. CONCLUSIONS Fertility seems to be slightly impaired in women with cystic fibrosis, because 37% of them failed to become pregnant without medical assistance. Because the outcome of pregnancies appears normal, patients should be informed about the possibility of becoming mothers and be made aware of the risk of unwanted pregnancies.

Abstract
With the growing class of CFTR modulator therapy available to more patients and with increasing pregnancies in individuals with CF, there is a growing need to understand the effects of these agents during pregnancy. There are few reports of their continued use in the literature, although it is likely that this is not an uncommon occurrence. We report the uncomplicated and successful pregnancy of a woman treated with lumacaftor/ivacaftor, as well as the clinical course of the infant during the first 9 months of life. We also report drug levels in plasma from the mother, cord blood, breast milk, and infant to estimate fetal and infant drug exposure.
