First Successful Pregnancy After Lung Transplantation in Poland-Case Report.

INTRODUCTION: Lung transplantation is well-established treatment for patients with advanced lung dysfunction in cystic fibrosis (CF). Pregnancy in CF lung transplant recipients is feasible, although it still remains challenging for even professionals and demands a multidisciplinary approach. CASE REPORT: We report the case of pregnancy in a 22-year-old woman after lung transplantation (LTx) due to end-stage respiratory failure in the course of CF. The interval from transplant to conception was 2.5 years. In 2019, orthotopic LTx was performed and a 3-drug immunosuppressive scheme was used-tacrolimus, mycophenolate mofetil, and prednisolone. There were no complications in the postoperative course. In April 2022, the patient was confirmed pregnant. All fetotoxic or teratogenic drugs were discontinued. Throughout the whole pregnancy, the patient was regularly monitored in the transplant and obstetrics centers. Due to the vaginal bleeding and irregular contractions at the 33 weeks of pregnancy, the course of steroids was administered. At 38 weeks and 5 days of gestation, she presented premature rupture of membranes. The caesarean section was performed because of breech presentation of the fetus. A live, term daughter was born and according to the screening test she does not have CF. Currently, 12 months after the delivery, the mother's lung function is good. CONCLUSIONS: Getting pregnant and having a safe pregnancy after LTx is possible, but it requires a specialized and individual approach. The patient should be well informed about possible complications and risks including graft failure. The patient's attitude and her cooperation with doctors play a major role.

Impact of Prolonged Cold Ischemia Time on Long-Term Survival in Lung Transplant Recipients.

BACKGROUND: Cold ischemia time (CIT) influences short- and long-term outcomes in lung transplant recipients. Most studies proved that prolonged CIT causes increased mortality. This study aimed to investigate the impact of prolonged CIT on patient survival time after lung transplantation (LTx). METHODS: The retrospective study group consisted of 139 patients who underwent double LTx in a single center between January 2018 and August 2022. Prolonged ischemic time (PIT) was defined as total ischemic time >6 hours and divided into smaller time intervals according to increasing PIT (6-8, 8-10, 10-12, >12 hours). The assessed outcomes were 1- and 4-year survival. RESULTS: Among the study group, PIT was observed in 98% (n = 137), and its average value was 10.33 hours. The prolonged CIT of 6 to 8 hours occurred in 10% (n = 14), 8 to 10 hours in 34% (n = 47), 10 to 12 hours in 36% (n = 49), and >12 hours in 20% (n = 27). In a comparison of 1-year survival between the PIT 6- to 10-hour group and the >10-hour arm (88% vs 78%), the difference was not statistically significant (P > .05). CONCLUSION: PIT is a risk factor for reduced long-term survival in LTx recipients. Increasing PIT may be associated with higher mortality at 1 and 4 years. All efforts to reduce the duration of ischemic time can benefit patient survival after LTx.

Kidney Transplantation as a Treatment Option of Chronic Renal Failure Among Lung Transplant Recipients: A Single-Center Experience.

INTRODUCTION: Chronic renal failure is one of the most common complications after solid organ transplantation. It is associated with multiple pre-, peri-, and post-transplant factors. In some patients, the available methods of conservative treatment are insufficient and kidney transplantation (KTx) is necessary. The aim of this study was to present our experience in the treatment of renal failure by KTx after lung transplantation (LTx). METHODS: Our study is a single-center retrospective review of clinical data of all 7 LTx recipients who underwent a KTx between the years 2013 and 2021. Patients' clinical condition, pulmonary function, renal function, and survival were examined. RESULTS: There were a total of 7 patients with medium age 36 years (±15). In 3 patients, the period of time from LTx to KTx was less than 3 years, and in 4 of them less than 13 years. Dialysis therapy was required in 4 patients. One patient had pre-LTx renal disease, while 6 patients had renal dysfunction related to post-transplant factors, including the use of calcineurin inhibitors. CONCLUSIONS: Renal protection is a very important aspect among LTx recipients; therefore, physicians must show a holistic and individual approach to patients and minimize exposure to nephrotoxic medication. Patients at high risk of developing chronic renal failure should be identified and, if required, renal replacement therapy should be initiated, including KTx.

Pediatric Lung Transplantations: New Possibilities and Challenges in Treatment of Children With End-Stage Respiratory Failure.

INTRODUCTION: Lung transplantation (LTx) is the last treatment option for children with end-stage respiratory failure. According to the literature, cystic fibrosis remains the most common cause of pediatric LTx. The study aimed to assess the characteristics of pediatric LTx recipients as well as the outcomes of the transplantation. METHODS: Our study is a single-center retrospective review of clinical data of all 11 patients who underwent a LTx before the age of 18 years between the years 2016 and 2020. Medical records were examined for patients' characteristics, general treatment, and complications. RESULTS: There were a total of 11 patients (8 males) with a median age 14.5 years (range: 11-17). The primary diseases that led to LTx were: cystic fibrosis in 8 patients (72.73%), hereditary hemorrhagic telangiectasia in 2 patients (18.18%), and idiopathic pulmonary arterial hypertension in 1 patient (9.09%). Median period from qualification to LTx was 235.55 days (range: 11-748). Two patients (18.18%) underwent lung retransplantation after 3 and 5 years. One patient passed away 10 months after surgery due to noncompliance. CONCLUSIONS: Pediatric lung transplantation is less common than lung transplantation in adults. It also differs in fields of donors accessibility, stronger immune system response and noncompliance that may lead to graft failure.

Expectations, symptoms, and quality of life before and after 1 year of Pirfenidone treatment in patients with idiopathic pulmonary fibrosis: A single-arm, open-label nonrandomized study.

Background and Aims: Antifibrotic therapies reduce lung function decline in patients with idiopathic pulmonary fibrosis (IPF). This single-arm, open-label, nonrandomized study aimed to determine the influence of antifibrotic treatment on patients' reported symptoms and expectations of the therapy. Methods: Fifty-two patients with confirmed IPF at a mean age of 65 ± 8.63 years (73% male) completed the following surveys at baseline and after 12 months of Pirfenidone treatment: Short Form Healthy Survey (SF-36), St. George's Respiratory Questionnaire (SGRQ), Baseline Dyspnea Index (BDI), Fatigue Assessment Scale (FAS), Leicester Cough Questionnaire (LCQ), and Patient's Needs and Expectations Authors' Survey. Results: The most important patients' needs were access to novel therapy, fast and easy access to health centers specializing in IPF treatment, and the improvement of the general condition or the maintenance of its level. These needs did not change with time, except for the significantly more important right of deciding on disease management after 12 months of treatment (p = 0.014). The quality of life per SF-36, after 1 year of Pirfenidone treatment, significantly improved in the physical cumulative score (p = 0.004) and mental cumulative score (p = 0.003). Significant deteriorations were observed in bodily pain and vitality. For the remaining questionnaires (SGRQ, BDI, FAS, and LCQ), no significant changes in the course of the study were noticed. Around one in 10 patients subjected to Pirfenidone therapy had achieved general symptom improvement in all areas; that is, quality of life improvement as well as cough and dyspnea reduction. Conclusions: One year of antifibrotic treatment resulted in a general improvement in the quality of life per the SF-36 questionnaire. Patients' expectations of disease management did not change; also, access to novel therapies and easy access to health centers specializing in IPF management remained their top needs.

Forced Oscillation Measurements in Patients with Idiopathic Interstitial Pneumonia Subjected to Pulmonary Rehabilitation.

(1) Background: Pulmonary rehabilitation (PR) plays a significant therapeutic role for patients with idiopathic interstitial pneumonia (IIP). The study assessed the impact of physical activity on lung function measured by forced oscillation technique (FOT). (2) Methods: The study involved 48 patients with IIP subjected to a 3-week inpatient PR. The control group included IIP patients (n = 44) on a 3-week interval without PR. All patients were assessed at baseline and after 3 weeks of PR by FOT, spirometry, plethysmography, grip strength measurement and the 6-minute walk test. (3) Results: There were no significant changes in FOT measurements in the PR group, except for reduced reactance at 11 Hz, observed in both groups (p < 0.05). Patients who completed PR significantly improved their 6-min walk distance (6MWD) and forced vital capacity (FVC). The change in 6MWD was better in patients with higher baseline reactance (p = 0.045). (4) Conclusions: Patients with IIP benefit from PR by an increased FVC and 6MWD; however, no improvement in FOT values was noticed. Slow disease progression was observed in the study and control groups, as measured by reduced reactance at 11 Hz. Patients with lower baseline reactance limitations achieve better 6MWD improvement.

COVID-19 Among Lung Transplant Recipients: A Single Center Study.

BACKGROUND: When COVID-19 became a pandemic, it was difficult to predict how it would affect lung transplant recipients. The aim of this study was to assess the mortality, influence on graft function as well as attitude toward SARS-CoV-2 vaccination among lung transplant recipients from a single center. METHODS: We analyzed medical data pertaining to 124 recipients who received lung transplants between 2008-2021 from a single center and original questionnaire on the COVID-19 severity classification system and the patients' attitude toward SARS-CoV-2 vaccination. Graft function was assessed by spirometry and a 6-minute walk test (6MWT), at least at the first postCOVID-19 visit. RESULTS: Among 29 patients who were confirmed to have COVID-19, 6 people died during or directly after contracting this infectious disease. The significant decrease in spirometry and distance in a 6MWT has been rarely observed in COVID-19 survivors. After vaccination ( n=107 patients) , most patients reported mild symptoms with slight pain and discomfort at the injection site being the most common (51.4%). 67.7% of all studiedpatients did not have any fears regarding the vaccination. Others reported being significantly worried about its effects (19.4% agreed to receive a vaccination anyway and 12.9% refused to be vaccinated). CONCLUSIONS: COVID-19 may present significant mortality among lung transplant recipients. The short-term safety and outcomes of vaccinations among these patients seemed encouraging. We are aware of the small study group limitations and hope to research this issue further.
