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.

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.

Lung Transplantation in Patients With Systemic Scleroderma-Description of the First Consecutive Cases in Poland: Case Series Report and a Short Literature Review.

Pulmonary complications of systemic scleroderma (SSc), such as interstitial lung disease and pulmonary hypertension (PH), are responsible for up to 60% of deaths among patients. For many years, most centers considered SSc a contraindication to lung transplantation (LTx); however, recent publications show that appropriately selected SSc candidates for LTx give results comparable to patients with idiopathic PH or idiopathic pulmonary fibrosis. This paper presents the cases of a 60-year-old male patient (patient 1) and a 42-year-old female patient (patient 2) diagnosed with SSc in 2019 and 2013, respectively. In both patients, interstitial-fibrotic changes in the lungs leading to respiratory failure were confirmed by high-resolution computed tomography as well as pulmonary hypertension (WHO group 3), which was also diagnosed during right heart catheterization. In both cases, despite pharmacotherapy, pulmonary fibrosis progressed, leading to severe respiratory failure. The patients were referred for LTx qualification. LTx was possible to consider in patients due to the lack of significant changes in other internal organs. Double LTx was successfully performed in both patients (patient 1-July 19, 2022; patient 2-September 14, 2022). They were discharged from the hospital in good condition on the 22nd and 20th postoperative day, respectively. LTx is a last-chance therapy that saves lives among patients with extreme respiratory failure in the course of SSc. It prolongs and improves the quality of life. The selection of appropriate patients is key to the success of the procedure.

Lung Transplantation in Patients With Pulmonary Hypertension With Extracorporeal Membrane Oxygenation (ECMO) Support: 5-Year Experience.

Lung transplantation (LTx) is the only treatment option of patients (pts) with pulmo-nary hypertension (PH) when pharmacologic treatment is unsatisfactory. ECMO is essential during LTx in every patient with pulmonary arterial hypertension and in most patients with sec-ondary PH. This is a retrospective, single-center study comparing LTx outcomes in patients with and without PH covering a 5-year experience. In the years 2018-2023, 219 LTx were performed, of which 56 (25.6%) with ECMO support, among which PH was diagnosed in 34pts (60.7%) in WHO groups 1,3,4: 19pts, 14pts. and 1pt respectively. The veno-arterial type of ECMO was used in patients with PH as intraoperative support (n = 34; 100%). The early (30-day) and long-term survival (1 year) of patients with and without PH did not differ statistically: 91.2% (95% CI: 82.1%-100%) vs. 77.3% (95% CI: 82.1%-100%)(P = .48) and 53.0% (95% CI: 36.6%-76.7 %) vs. 41.3% (95%CI: 23.1-74.0) (P = .48) respectively and the median hospitalization time from ECMO weaning to dis-charge was also comparable: 31 days (Q1-Q3: 21-40; IQR 20) vs. 28 days (Q1-Q3: 24-42; IQR :18) (P = .99). Patients with or without PH undergoing LTx with ECMO have comparable survival and hospital stay outcomes despite being the most challenging of all lung diseases treated with lung transplantation.

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.

Condition of the Oral Cavity in Patients After Heart Transplantation: A Preliminary Report.

BACKGROUND The constant impairment of the immune system caused by lifelong use of immunosuppressive drugs in patients after heart transplantation has a significant impact on oral cavity health. The aim of this study was to analyze the health of the oral cavity in patients after heart transplantation, with particular regard to occurring pathogens. MATERIAL AND METHODS The study included 25 patients after heart transplantation. The research scheme was divided into 2 parts. The first part consisted of a survey on general health and oral hygiene habits. The second part of the examination consisted of an analysis of the health of the oral cavity: the mucosa, periodontium, and hard dental tissues. Particular attention was paid to PET (test for the presence of pathogens causing periodontitis/periimplantitis) and CAT (diagnostic test for the presence of Candida in the oral cavity), which are real-time PCR tests used to detect pathogens causing periodontitis and microorganisms present in oral candidiasis. RESULTS The conducted research and in-depth analysis of the results showed that the oral health condition in patients after heart transplantation is not satisfactory, regardless of the time that has elapsed since the surgery, sex, age, hygiene habits, or the type of immunosuppression used. The oral cavity of patients after heart transplantation is colonized with Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, and Candida albicans. CONCLUSIONS The cooperation of the dentist with the attending physician at each stage of the treatment should play an unquestionable role.

Novel Hybrid Treatment for Pulmonary Arterial Hypertension with or without Eisenmenger Syndrome: Double Lung Transplantation with Simultaneous Endovascular or Classic Surgical Closure of the Patent Ductus Arteriosus (PDA).

Patients with pulmonary arterial hypertension (PAH) become candidates for lung or lung and heart transplantation when the maximum specific therapy is no longer effective. The most difficult challenge is choosing one of the above options in the event of symptoms of right ventricular failure. Here, we present two female patients with PAH: (1) a 21-year-old patient with Eisenmenger syndrome, caused by a congenital defect-patent ductus arteriosus (PDA); and (2) a 39-year-old patient with idiopathic PAH and coexistent PDA. Their common denominator is PDA and the hybrid surgery performed: double lung transplantation with simultaneous PDA closure. The operation was performed after pharmacological bridging (conditioning) to transplantation that lasted for 33 and 70 days, respectively. In both cases, PDA closure effectiveness was 100%. Both patients survived the operation (100%); however, patient no. 1 died on the 2nd postoperative day due to multi-organ failure; while patient no. 2 was discharged home in full health. The authors did not find a similar description of the operation in the available literature and PubMed database. Hence, we propose this new treatment method for its effectiveness and applicability proven in our practice.

Assessment of Anti-Human Leukocyte Antigen (HLA)-Antibody-Dependent Humoral Response in Patients before and after Lung Transplantation.

Background and Objectives: Testing for anti-human leukocyte antigen (HLA) antibodies both before and after transplantation is of fundamental significance for the success of lung transplantation. The aim of this study was the evaluation of anti-HLA immunization of patients before and after lung transplant who were subjected to qualification and transplantation. Materials and Methods: Prior to the transplantation, patients were examined for the presence of IgG class anti-HLA antibodies (anti-human leukocyte antigen), the so-called panel-reactive antibodies (PRA), using the flow cytometry method. After the transplantation, the class and specificity of anti-HLA antibodies (also IgG) were determined using Luminex. Results: In the group examined, the PRA results ranged from 0.1% to 66.4%. Low (30%) and average (30-80%) immunization was found in only 9.7% of the group examined. Presence of class I anti-HLA antibodies with MFI (mean fluorescence intensity) greater than 1000 was found in 42.7% of the patients examined, while class II anti-HLA antibodies were found in 38.4%. Immunization levels before and after the transplantation were compared. In 10.87% of patients, DSA antibodies (donor-specific antibodies) with MFI of over 1000 were found. Conclusions: It seems that it is possible to confirm the correlation between pre- and post-transplantation immunization with the use of the two presented methods of determining IgG class anti-HLA antibodies by increasing the size of the group studied and conducting a long-term observation thereof.

Double Lung Transplantation for Idiopathic Pulmonary Fibrosis in a Patient with a History of Liver Transplantation and Prolonged Journey for Disease-Specific Antifibrotic Therapy.

Idiopathic pulmonary fibrosis (IPF) is characterized by uncontrolled progressive lung fibrosis with a median survival of 3 to 5 years. Although currently available pharmacotherapy cannot cure the disease, antifibrotics including pirfenidone and nintedanib were shown to slow disease progression and improve survival in IPF. Nevertheless, there is a knowledge gap on the safety of antifibrotics in patients after liver transplantation receiving concomitant immunosuppressive therapy. This case report of a 68-year-old male patient with IPF illustrates how a complex medical history has led to diagnostic and therapeutic challenges considerably affecting clinical decisions and impacting the patient's journey. The increasing severity of lung function impairment due to the progressive natural history of IPF ultimately led to severe respiratory failure. Double lung transplantation (LTx) was performed as the only therapeutic option in end-stage disease with the potential to improve quality of life and survival. To the best of our knowledge, this is the first case report describing the feasibility and safety of antifibrotic therapy with pirfenidone for IPF in a 68-year-old patient with a history of liver transplantation receiving concomitant immunosuppressive therapy with tacrolimus who underwent successful double lung transplantation when alternative medical interventions had been exhausted.

The Quality of Sex Life Among Patients Before and After Lung Transplantation: A Single-Center Study.

BACKGROUND: Lung transplantation (LTx) is the only effective method of treatment for patients with end-stage lung diseases; LTx prolongs and increases the quality of life (QoL). An important aspect of QoL that changes in the course of severe diseases is the quality of sex life. This aspect is yet to be discussed in relationship to LTx. We aim to compare patients' quality of sex life at the qualification process with patients' who underwent LTx. METHODS: The studied group consisted of 100 patients (24 women before and 16 after LTx, 39 men before and 21 after LTX) who were admitted to the lung transplantology department for qualification or to control the function after LTx. To assess the patients' quality of sex life, we used The Changes in Sexual Functioning Questionnaire (CSFQ) and World Health Organization (WHO) QoL-BREF. To assess lung function, patients underwent a 6-Minute-Walk-Test (6MWT). RESULTS: Patients after LTx obtained higher results-compared to patients qualified for LTx-in the WHO QoL-BREF in every domain (somatic, psychological, social, and environment). Men after LTx got more points in every domain and better total score (53 ± 5.62 vs 44.23 ± 10.28 point; P < .05) in CSFQ. Women before and after LTx obtained comparable results in CSFQ. Results of 6-Minute-Walk-Test were better among patients after LTx than in qualified patients (523.62 ± 95.71 vs 333.14 ± 145.38 and 524.12 ± 56.17 vs 317.20 ± 141.6, respectively for men and women). CONCLUSIONS: Patients after LTx show better pulmonary function and quality of sex life than qualified. Preliminary results encourage us to conduct research on a larger group.

Lung Transplant as a Treatment for Patients with End-Stage Respiratory Failure Due to COVID-19.

BACKGROUND: COVID-19 may lead to development of irreversible acute respiratory distress syndrome. Some patients sustain severe respiratory failure after infection subsides. They may require lung transplant as a last resort treatment. The aim of the study is to assess the effect and feasibility of lung transplant as a treatment for patients with severe irreversible respiratory failure due to COVID-19. METHODS: This retrospective study pertains to analysis of 119 patients in critical condition who were referred to Lung Transplant Ward (Zabrze, Poland). between July 2020 and June 2021 after developing respiratory failure requiring extracorporeal membrane oxygenation, invasive ventilation, or both, as well as a few patients on high-flow oxygen therapy. Inclusion criteria for referral were confirmed lack of viral disease and exhaustion of other therapeutic options. RESULTS: Of the referred patients, 21.84% were disqualified from such treatment owing to existing contraindications. Among the suitable patients, 75.8% died without transplant. Among all patients who were qualified for lung transplant, only 9 patients became double lung transplant recipients. Intraoperative mortality for this procedure was 33%. Four patients were discharged after the procedure and are currently self-reliant with full respiratory capacity. CONCLUSIONS: Patients with severe irreversible respiratory failure after COVID-19 present significantly high mortality without lung transplant. This procedure may present satisfactory results but must be performed in a timely fashion owing to critical condition and scarcity of lung donors, only aggravated around the time of peak infection waves.

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.

First in Poland Simultaneous Liver-Lung Transplantation With Liver-First Approach for Recipient Due to Cystic Fibrosis: A Case Report.

Cystic fibrosis is an autosomal progressive disease affecting the lung, pancreas, and liver. Some patients develop end-stage respiratory and liver failure. For such patients, combined lung-liver transplantation remains the only therapeutic option. In this article we present the first simultaneous lung-liver transplantation in Poland, as well as in Central and Eastern Europe, with detailed clinical history, surgical aspects, and postoperative course.

Results of Lung Transplantations Among Cystic Fibrosis Patients: A Single-Center Study.

BACKGROUND: Lung transplantation remains the ultimate treatment for patients who have exhausted all other therapeutic options in the course of end-stage lung disease due to cystic fibrosis (CF). The aim of the study was to assess the results of lung transplantations performed via mini-thoracotomy in a single center. METHODS: This retrospective study assesses the survival and need for reoperation among 56 primary lung transplant recipients due to CF in a single center between 2018 and 2021. Intraoperative death was also assessed, yet it was established as an exclusion criterion for the post-transplant survival analysis. RESULTS: Only one patient died intraoperatively (1.79%). Reoperation at an early postoperative stage was required among 2 patients (3.58%), due to vascular complication for one and pulmonary leakage for the other. Mortality at 30 days was 0%. In-hospital mortality was low (3.58%). Survival at 1, 2, and 3 years was respectively 87%, 85%, and 75%. Mean forced expiratory volume in 1 second as a percentage of predicted value at discharge was approximately 60% and did not decrease after 12 and 24 months. Mean BMI at 12-month follow-up was 20.11 (range, 13-28.7) with 71.4% of patients being qualified as presenting within the normal range of 18.5 to 24.9. CONCLUSIONS: Double lung transplantation is a safe and feasible surgical option. Despite being more technically difficult and challenging than clamshell approach for surgeons, it is more beneficial for patients.

Various Aspects of Bacterial Infections in the Early Postoperative Stage Among Lung Transplant Recipients on Broad-Spectrum Antibiotics: A Single Center Study.

BACKGROUND: Life-long immunosuppression after lung transplantation increases the risk of bacterial infections, hence broad-spectrum antibiotics can be implemented after transplant. The aim of this study is to assess various aspects of bacterial infections in the early postoperative stage among lung transplant recipients on broad-spectrum antibiotics at a single center. METHODS: This retrospective study consists of 134 primary lung transplant recipients transplanted between 2014 and 2021 at a single center. Study analyzed the occurrence of de novo bacterium in bronchoalveolar lavage sampled 2 to3 weeks after lung transplantation, as well as survival and the occurrence of bacterial sepsis. Studied antibiotics include linezolid, meropenem, tobramycin, and cloxacillin. RESULTS: None of the patients from the broad-spectrum antibiotics developed bacterial sepsis within the first 30 postoperative days. In-hospital mortality due to bacterial sepsis among patients in the broad-spectrum group was 1.89%. The most common new pathogen in first couple of days after lung transplantation was Burkholderia multivorans (42%). After its occurrence, Ceftazidime was administered. It significantly reduced the occurrence of hospital-acquired B multivorans after 2 to 3 weeks post-transplant (χ2 = 8.01, P = .005). CONCLUSION: Broad-spectrum antibiotics seem to be an efficient approach against bacterial infections for lung transplant recipients in the early post-transplant period, as patients treated this way very rarely develop fatal bacterial infections in the studied period. Ceftazidime proved efficient for treatment for B multivorans among the studied group. Patients, who acquired new pathogen during post-transplant hospital stay presented comparable lung function at discharge in comparison to those who were not.

Influence of Bronchoscopic Interventions on Graft Function of Double Lung Transplant Recipients due to Cystic Fibrosis.

BACKGROUND: Healing of bronchial anastomoses may sometimes be complicated and require bronchoscopic intervention (BI). The main aim of the study was to assess whether patients who require BI present comparable lung function after reaching 1-year posttransplant survival to those who did not require any BI by means of spirometry and 6-minute walk test (6MWT). METHODS: This retrospective study included an analysis of 44 primary double lung transplant recipients who underwent transplant for end-stage respiratory failure in the course of cystic fibrosis transplanted in a single center between 2018 and 2021. Bronchoscopic intervention is defined as performing endoscopic bronchoplasty through balloon dilatation, cryoprobe, argon plasma, and/or laser treatment. Group 1 (25 patients who required at least 1 BI) presented similar spirometry parameters at qualification as group 2 (no BI). RESULTS: Statistically significant differences between the groups for the following parameters were reported: forced expiratory volume in 1 second (FEV1), FEV1 (%), Tiffeneau-Pinelli index (FEV1/forced vital capacity percentage of predicted value), oxygen saturation after conclusion of 6MWT (%) and oxygen saturation before 6MWT (%). In each case, the mean for the BI group in the first year was lower. All patients in this group received an average amount of 6.8 ± 4.9 bronchoscopic procedures during the first year (minimum = 1; maximum = 18). Strong negative correlations were observed between the number of balloons in the first year and the FEV1 (%) and FEV1/forced vital capacity percentage of predicted value indicators after the first year. CONCLUSIONS: Lung transplant recipients who underwent transplant because of cystic fibrosis and required at least 1 BI during the first posttransplant year presented inferior spirometry and 6MWT results in comparison with those who did not require any.

Diagnostics of the Epstein-Barr Virus Before and After Lung Transplantation in a Patient With Developing Posttransplant Lymphoproliferative Disease: A Case Report.

The most important risk factor for the development of posttransplant lymphoproliferative disorders (PTLD) is Epstein-Barr virus (EBV) infection after transplant. It increases in seronegative EBV recipients from 23% to 50%. The aim of the study was to assess the serologic status of EBV infections (before lung transplant) and the expression of the virus itself after lung transplant in a 25-year-old patient with cystic fibrosis. In a 25-year-old patient with cystic fibrosis, immediately before lung transplant, all diagnostically significant antibodies related to EBV infection were determined in blood serum using enzyme-linked immunosorbent assay methods, using tests by Euroimmun and PerkinElmer Company. Additionally, the organ donor's serologic profile was assessed with the same tests. After lung transplant, the risk of EBV infection was monitored in whole blood and virus expression was determined by reverse transcriptase-polymerase chain reaction with Biomerieux Argene tests. Before lung transplant, the patient was shown to have no antibodies against EBV in both IgM and IgG classes. The constellation of organ donor antibodies clearly indicated a past infection. The presence of EBV virus copies in whole blood was demonstrated in the patient 9 months after transplant. Constant monitoring of the patient and modification of the treatment did not, unfortunately, protect him from the development of PTLD. The obtained results clearly confirm the purposefulness of both serologic and molecular determinations in lung recipients related to EBV. The likelihood of developing PTLD increases both in people who have not had EBV infection and patients with reactivation of the infection.

Effect of Bronchoscopic Interventions on Long-Term Lung Function Among Lung Transplant Recipients due to Cystic Fibrosis: A Single-Center Study.

BACKGROUND: Patients with end-stage lung disease owing to cystic fibrosis may require lung transplant, provided other therapeutic options were exhausted. During the posttransplant period, bronchial anastomoses' healing may sometimes be complicated and require bronchoscopic intervention (BI). The main aim of this study was to assess BI and its effect on long-term lung function among cystic fibrosis lung transplant recipients who have reached 2-year survival. METHODS: This retrospective study includes 22 patients with cystic fibrosis who underwent primary double lung transplant in a single center between 2018 and 2020 and have checked in for their 2-year follow-up visit. BI is defined as performing endoscopic bronchoplasty through balloon dilatation, cryoprobe, argon plasma, and/or laser treatment. RESULTS: All patients, who did not require BI during the first year, did not need bronchoplasty during the second posttransplant year as well. Results of forced expiratory volume in 1 second as percentage of predicted value and the 6-minute walk distance were similar at 2-year follow-up to those obtained at the end of 1 year for all patients. Significant time effects were observed for forced vital capacity (FVC) (weak effect), FVC as percentage of predicted value (weak effect), and forced expiratory volume in 1 second/FVC (moderate effect). CONCLUSIONS: Patients who had never had bronchoscopic intervention owing to airway stenosis, as well as those who did in the first posttransplant year, maintained forced expiratory volume in 1 second as percentage of predicted value at a comparable level at the second posttransplant year follow-up visit. The number of BIs significantly decreased among patients, who were undergoing such procedures during the first posttransplant year.

Antifungal Prophylaxis and Treatment Among Lung Transplant Recipients in Early Postoperative Stage: A Single-Center Study.

BACKGROUND: Lung transplantation remains the only feasible option for certain patients with end-stage lung disease. Lifelong immunosuppression increases the risk of infection, including fungal infections. The aim of this study was to assess the effect of antifungal prophylaxis and treatment among lung transplant recipients in the early postoperative stage. METHODS: This retrospective analysis included 127 patients who underwent lung transplantation between 2014 and 2021 in the lung transplant ward, 65.35% of whom were males. The most common indication for lung transplantation was cystic fibrosis (n = 59; 46.46%). All of the patients were receiving inhaled amphotericin B. Within this group there were patients who also were treated with intravenous caspofungin, intravenous/oral voriconazole, or both. RESULTS: The difference in the efficacy against Candida spp. between caspofungin and voriconazole in the early post-transplant period was not statistically significant (χ2 = 0.5, P = .477). Moreover, the difference in the efficacy against Candida spp. between itraconazole and voriconazole during the first post-transplant year was not statistically significant (χ2 = 0.46, P = .496). CONCLUSION: Caspofungin and voriconazole are proper and relatively efficient antifungal prophylaxis and treatment options after lung transplantation. There was no significant difference between voriconazole and caspofungin as antifungal agents used in the early post-transplant stage. There was no significant difference between voriconazole and itraconazole as antifungal agents used during the first post-transplant year. Further research on this issue is required.
