Clinical impact of pre-existing acute exacerbation in patients with interstitial lung disease who underwent lung transplantation. Respir Res 2023; 24:307. [PMID: 38062465 PMCID: PMC10701919 DOI: 10.1186/s12931-023-02614-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 11/22/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Acute exacerbation of interstitial lung disease (AE-ILD) significantly impacts prognosis, leading to high mortality rates. Although lung transplantation is a life-saving treatment for selected patients with ILD, its outcomes in those presenting with AE-ILD have yielded conflicting results compared with those with stable ILD. This study aims to investigate the impact of pre-existing AE on the prognosis of ILD patients who underwent lung transplantation. METHOD We conducted a single-center retrospective study by reviewing the medical records of 108 patients who underwent lung transplantation for predisposing ILD at Asan Medical Center, Seoul, South Korea, between 2008 and 2022. The primary objective was to compare the survival of patients with AE-ILD at the time of transplantation with those without AE-ILD. RESULTS Among the 108 patients, 52 (48.1%) experienced AE-ILD at the time of lung transplantation, and 81 (75.0%) required pre-transplant mechanical ventilation. Although the type of ILD (IPF vs. non-IPF ILD) did not affect clinical outcomes after transplantation, AE-ILD was associated with worse survival outcomes. The survival probabilities at 90 days, 1 year, and 3 years post-transplant for patients with AE-ILD were 86.5%, 73.1%, and 60.1%, respectively, while those for patients without AE-ILD were higher, at 92.9%, 83.9%, and 79.6% (p = 0.032). In the multivariable analysis, pre-existing AE was an independent prognostic factor for mortality in ILD patients who underwent lung transplantation. CONCLUSIONS Although lung transplantation remains an effective treatment option for ILD patients with pre-existing AE, careful consideration is needed, especially in patients requiring pre-transplant mechanical respiratory support.

Incidence, risk factors, and clinical characteristics of airway complications after lung transplantation. Sci Rep 2023; 13:667. [PMID: 36635329 PMCID: PMC9837050 DOI: 10.1038/s41598-023-27864-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 01/09/2023] [Indexed: 01/14/2023] Open
Abstract
Airway complications may occur after lung transplantation and are associated with considerable morbidity and mortality. We investigated the incidence, risk factors, and clinical characteristics of these complications. We retrospectively reviewed the medical records of 137 patients who underwent lung transplantation between 2008 and 2021. The median follow-up period was 20 months. Of the 137 patients, 30 (21.9%) had postoperative airway complications, of which 2 had two different types of airway complications. The most common airway complication was bronchial stenosis, affecting 23 patients (16.8%). Multivariable Cox analysis revealed that a recipient's body mass index ≥ 25 kg/m2 (hazard ratio [HR], 2.663; p = 0.013) was a significant independent risk factor for airway complications, as was postoperative treatment with extracorporeal membrane oxygenation (ECMO; HR, 3.340; p = 0.034). Of the 30 patients who had airway complications, 21 (70.0%) were treated with bronchoscopic intervention. Survival rates did not differ significantly between patients with and without airway complications. Thus, our study revealed that one fifth of patients who underwent lung transplantation experienced airway complications during the follow-up period. Obesity and receiving postoperative ECMO are risk factors for airway complications, and close monitoring is warranted in such cases.

Kim OH, Shim TS, Jo KW. Drug-level change and optimal dose adjustment of tacrolimus with the use of rifabutin for treating mycobacterial disease in solid organ transplant recipients. Transpl Infect Dis 2022; 24:e13893. [PMID: 35822673 DOI: 10.1111/tid.13893] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 05/24/2022] [Accepted: 06/14/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Little is known about the change in drug level and the need for dose adjustment of calcineurin inhibitor when it is used with rifabutin in solid organ transplant (SOT) recipients. We aimed to analyze whether the drug level of tacrolimus significantly reduced after the use of rifabutin and to assess optimal adjustment of tacrolimus dose in SOT recipients. METHODS Of the SOT recipients in a tertiary referral center in South Korea in 2000-2019, 50 patients who maintained an unchanged dose of tacrolimus after the use of rifabutin for treating mycobacterial disease were enrolled. Their medical records were reviewed retrospectively. RESULTS The mean age of the patients was 53.9 ± 11.5 years. The most commonly transplanted organ was the liver (66.0%). The most common indication of rifabutin use was for treating active tuberculosis (78.0%). After rifabutin initiation, the trough level of tacrolimus decreased significantly to the subtherapeutic range in 38 (76.0%) patients. The drug levels of these 38 patients dropped from 7.2 to 3.8 ng/mL (p < 0.001) after rifabutin treatment. In these patients, the median 1.5-fold increase in the tacrolimus dose was required to restore the drug level to the within-therapeutic range. CONCLUSIONS These findings indicate that careful tacrolimus drug-level monitoring and dose adjustment are necessary for most SOT recipients when rifabutin is administered for the treatment of mycobacterial disease.

Looking Beyond the Allograft Survival: Long-Term, 5-Year Renal Outcome in Lung Transplant Recipients. Transplant Proc 2021; 53:3065-3068. [PMID: 34756711 DOI: 10.1016/j.transproceed.2021.09.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 09/17/2021] [Accepted: 09/30/2021] [Indexed: 11/22/2022]
Abstract
With the increased incidence and survival of lung transplant (LTx) recipients, the risk for chronic sequelae such as chronic kidney disease (CKD) is on the rise. Data on the long-term renal outcome are scarce. We performed a retrospective chart review of 171 adults with LTx from January 1, 2014, to January 1, 2019. Primary outcomes were prevalence of CKD/end-stage renal disease, acute kidney injury (AKI) as a risk factor for future CKD, and all-cause mortality in recipients with CKD compared with the non-CKD group. Secondary outcomes were frequency of utilization of modalities for CKD (urinalysis, imaging, biopsy, nephrology consultations). Baseline median creatinine and estimated glomerular filtration rate (eGFR) were 0.8 mg/dL and 90 mL/min/1.73 m2, respectively. Of the participants, 60% (96 of 161), 67% (102 of 153), 79% (37 of 47), 86% (10 of 12) had CKD at the end of 6, 12, 36, and 60 months, respectively, and 16% were on dialysis at the end of the study period; 3% received a subsequent renal transplant, and 27% mortality was noted over a 5-year follow-up period. The odds of CKD development in patients with an AKI during index hospitalization vs no AKI was 6.22 (2.87 to 13.06, P < .0001). The odds ratio of all-cause mortality in patients with CKD compared with non-CKD was 3.36 (95% confidence interval, 1.44-8.64, P = .005). Measurement of hematuria/proteinuria, imaging, and renal biopsy were infrequently used. Given the high prevalence of AKI and CKD in this population, a multidisciplinary team approach with an early nephrology consultation will be key to improve the overall and renal outcomes in LTx recipients.
