  Abstract 


The science and practice of organ transplant have evolved, and a lung transplant is now a viable option that can add years and quality to life. The connective tissue diseases (CTDs) at present form a very small percentage of the indications for which lung transplants are done today. Patients with interstitial lung disease or those with respiratory failure as a result of pulmonary vascular disease may benefit from transplants if done in the right setting. The various nonpulmonary manifestations of CTDs influence the odds of the success of a lung transplant and need to be taken into account beforehand. Evaluation of the individual candidate, ensuring disease remission at the time of the transplant, anticipating the surgical and anesthetic challenges and the postsurgical intensive care-related challenges is important. Careful patient selection and meticulous preprocedure evaluation are likely to result in good outcomes.

  Introduction Top


The proportion of lung transplantations (LT) performed for connective tissue diseases (CTD) is small, accounting for 0.9% of all cases being reported to the International Society for Heart and LT in 2019.[1] Rheumatoid arthritis (RA) and undifferentiated CTD (UCTD), followed by scleroderma, account for more than 70% of these transplants.[1] The concern about LT in CTDs is because of the presence of unfavorable risk factors for posttransplant outcomes in these patients (notably esophageal disease, bone marrow involvement, cardiac disease, and pulmonary hypertension [PH]), the association with preformed anti-HLA antibodies, the difficulty in distinguishing posttransplant rejection from severe flares of CTDs and concerns about long-term outcome in this group of patients.[2],[3],[4] Several carefully selected cohorts show excellent outcomes and we review the relevant literature addressing these concerns.


  Connective Tissue Diseases and Associated Pulmonary Syndromes Top


Five major CTDs, namely systemic lupus erythematosus, systemic sclerosis (SSc), inflammatory myositis, RA, and Sjogren's syndrome,[5],[6],[7],[8],[9] can all have associated ILD. In addition, ILD can be associated with overlap syndromes like mixed connective tissue disorder, as well as with UCTD. Further, a significant proportion of patients with ILD manifest some autoimmune features but do not fulfill the criteria for a definitive CTD and are referred to as Interstitial Pneumonia with Autoimmune Features.[10] The pulmonary vasculitis syndromes are diseases characterized by primary damage to the small blood vessels in the pulmonary tree and are included here because the concerns about LT for pulmonary vasculitis are similar to those with the CTD syndromes. A wide variety of pleuropulmonary manifestations have been reported with the CTD syndromes. These manifestations may lead to respiratory failure, necessitating evaluation for LT. Some of the features associated with CTDs may also impact transplant candidacy or are contraindications to LT, e.g., shrinking lung syndrome.[11],[12],[13],[14],[15]


  Extrapulmonary Conditions Associated with Connective Tissue Diseases Relevant to Lung Transplantation Top


The CTD syndromes have characteristic but variable extrapulmonary manifestations. Several of these are absolute contraindications to LT or place prospective lung transplant recipients at substantially higher risk after LT. Specific attention is paid to cardiac involvement, right ventricular function, and PH in SSc-ILD. PH in SSc-ILD can be due to pulmonary arterial hypertension (Group 1), extensive interstitial lung disease and sleep apnea (Group 3), left heart disease or diastolic dysfunction (Group 2), pulmonary thromboembolism (Group 4), or venous-occlusive disease. Phenotyping before LT is important for management in the perioperative period.


  Listing Criteria and Contraindications to Lung Transplantation in General Top


The indications for referral and listing for LT are usually related to interstitial lung disease and PH related to the CTD syndrome. The usual listing criteria for both these indications are summarized in [Table 1]. There are several absolute contraindications to LT as well as factors that place recipients at substantially high-risk posttransplantation; these have been summarized in [Table 2]. Severe esophageal dysmotility, kidney disease with glomerular filtration rate <60 mL/min, bone marrow involvement due to disease or therapy, coronary artery disease related to accelerated atherosclerosis, and severe PH are of particular relevance to patients with CTDs.[16]

  Candidate Evaluation for Lung Transplantation in Connective Tissue Diseases Top


The evaluation for LT in a patient with CTD proceeds as in any patient for LT; in addition, careful attention is paid to the extrapulmonary manifestations that are of relevance to a patient undergoing transplantation by focused investigations [Table 3]. The specific contraindications or risk factors for poor outcomes in patients with individual CTDs in addition to factors previously listed in [Table 2] are summarized in [Table 4]. In patients with scleroderma, discussion on the expected period of nil per oral after transplant and the use of postpyloric feeds should occur before listing.[2]

Connective tissue disease remission before transplant

The CTD must be in remission before the transplant. This requires coordination between the transplant team and the rheumatologist. Rarely, LT evaluation is undertaken in the setting of recent life-threatening activity like severe lupus pneumonitis or anti-MDA5 syndrome.

Surgical and anesthesia-related challenges

Transplant procedure

Bilateral LT (BLT) is usually the procedure of choice given the younger age and PH in patients with CTD. Patients with severe structural or cardiac functional abnormalities or dysfunction, not likely to improve with normalization of pulmonary pressures, in conjunction with intrinsic lung disease or severe PH, are considered for heart-lung transplant. This decision must be balanced with the likelihood of recovery of right ventricle failure (RV) after BLT in the absence of objective assessment of infarcts or fibrotic changes of the RV.

Bridging

Patients with right ventricular dysfunction related to PH may need bridging with venoarterial-extracorporeal membrane oxygenation (VA-ECMO), while interstitial lung disease alone can be bridged with venovenous-ECMO (VV-ECMO).

Anaesthesia and intra-operative hemodynamic support and monitoring

Difficult airway and intubation-related cervical subluxation can occur in patients with microstomia and RA respectively, and awareness reduces these complications. Particular care during anesthesia induction in patients with PH is essential to prevent hemodynamic collapse. In this case, awake VA-ECMO provides preoperative cardiovascular support, avoids cardiac arrest related to induction, and is a useful adjunct for continued intraoperative and postoperative support. The goal includes avoiding increasing pulmonary vascular resistance, maintaining preload while avoiding fluid overload, reducing RV afterload, and reducing tachycardia. The use of a pulmonary artery catheter to monitor pressures and cardiac output is essential during surgery.

Patients with CTD-ILD have small chest cavities and PH, and intra-operative central VA-ECMO helps avoid hypotension during cardiac retraction. Transesophageal echocardiography guides the management of right ventricular function intraoperatively.

Patients with CTD are at higher risk of vascular access-related complications such as hematomas, pseudoaneurysms, fistulas, and limb ischemia. Use of ultrasound and restricting radial artery and subclavian access duration along with the use of topical nitroglycerin, warm gloves, blankets as adjuncts can potentially reduce complications. Avoiding vasopressors and optimizing fluid and cardiac function can help avoid extremity vessel and coronary artery spasm as complications.


  Intensive Care Challenges Top


Cardiac management

Cardiac dysfunction can be related to left ventricular diastolic dysfunction; SSc-related right ventricular dysfunction; PH-related post-LT left ventricular systolic dysfunction; tachyarrhythmias and constrictive pericarditis. There is an association between CTD-ILD and primary graft dysfunction (PGD); this is possibly confounded by the association of PH in CTD leading to PGD; optimizing other donor and recipient factors could potentially reduce PGD incidence.

The use of low tidal volume ventilation (6 mL/kg) and donor lung size-guided volume-based ventilation can also reduce PGD incidence. A conservative fluid strategy is preferred to avoid unfavorable right ventricular preload and flooding the allograft; low-dose vasopressors can help if hemodynamic support is required despite appropriate fluid resuscitation. Inhaled nitric oxide has favorable pulmonary vasodilator activity and is useful in the setting of persistent PH with reduced cardiac output. Severe right ventricular dysfunction requires VA-ECMO support postoperatively.

Weaning

Patients with ILD retain rapid shallow breathing patterns in the early transplant period and patients whose work of breathing during spontaneous breathing is normal should be considered for a trial of extubation.

Acute kidney injury

Acute kidney injury is often a concern in patients with CTD because of renal involvement, especially in SSc-ILD. Scleroderma renal crises can occur in up to 5-10 percent of patients with SSc. Avoiding high dose steroids postoperatively, blood pressure management, and use of tacrolimus (over cyclosporine) can avoid renal injury in this setting. In other CTD patients, good hemodynamic management and aggressive management of infections prevent kidney injury.

Gastroesophageal reflux and gastroparesis

Multidisciplinary management of scleroderma with speech pathologists, gastroenterologists, nutritionists, pulmonologists, and surgeons is required to device a plan for these complex patients as there is no consensus on management of patients with esophageal dysmotility postoperatively. Keeping nil per oral, liberal use of prokinetics, attention to the texture of allowed enteral diet, and exclusive use of postpyloric tubes postoperatively till 3–6 months is recommended to avoid reflux, aspiration, and early allograft dysfunction. Patients with Sjogren's syndrome may require artificial saliva due to xerostomia and attention to oral candidiasis postoperatively.

pH manometry and gastric emptying are repeated 6–12 weeks postoperatively. In patients with severe gastroparesis postoperatively, prokinetics agents and antiemetics are the first-line treatment. In patients with refractory symptoms, placement of a venting gastrostomy-jejunostomy tube allows patients to maintain good nutrition. Gastric electrical stimulation and postpyloric botulinum toxin-A injection have been reported in refractory cases. A surgical fundoplication is an option in patients who are clinically stable about 3 months from their transplantation with refractory gastroparesis.


  Survival and Outcomes of Patients with Connective Tissue Diseases after Lung Transplantation Top


Small single-center series of carefully selected patients with SSc-ILD show similar outcomes with no difference in rates of acute rejection or long-term survival [Table 5]. The data on other CTDs are smaller but promising.[27]

  Conclusion Top


Lung transplant has emerged as an option in patients with advanced pulmonary involvement as a result of CTDs. The nonpulmonary manifestations pose a significant challenge in the success of transplant in patients with CTD-related pulmonary disease. A thorough evaluation and selection of the right transplant candidates are important determinants of the success of the procedure.
