Rationale: Nontuberculous mycobacterial (NTM) diseases are difficult-to-treat infections, especially in lung transplant (LTx) candidates. Currently, there is a paucity of recommendations on the management of NTM infections in LTx, focusing on Mycobacterium avium complex (MAC), M. abscessus and M. kansasii ., Methods: Pulmonologists, infectious disease specialists, LTx surgeons and Delphi experts with expertise in NTM were recruited. A patient representative was also invited. Three questionnaires comprising questions with multiple response statements were distributed to panellists. Delphi methodology with a Likert scale of 11 points (5 to -5) was applied to define the agreement between experts. Responses from the first two questionnaires were collated to develop a final questionnaire. The consensus was described as a median rating >4 or <-4 indicating for or against the given statement. After the last round of questionnaires, a cumulative report was generated., Results: Panellists recommend performing sputum cultures and a chest computed tomography scan for NTM screening in LTx candidates. Panellists recommend against absolute contraindication to LTx even with multiple positive sputum cultures for MAC, M. abscessus or M. kansasii. Panellists recommend MAC patients on antimicrobial treatment and culture negative can be listed for LTx without further delay. Panellists recommend 6 months of culture-negative for M. kansasii , but 12 months of further treatment from the time of culture-negative for M. abscessus before listing for LTx., Conclusion: This NTM LTx study consensus statement provides essential recommendations for NTM management in LTx and can be utilised as an expert opinion while awaiting evidence-based contributions., Competing Interests: Conflict of interest: H.

A variety of phenotypic categorisations have been developed for sarcoidosis. Phenotyping has been used for genetics studies and to guide treatment selection. The authors participated in a Delphi expert consensus panel to develop a proposed phenotype categorisation and treatment recommendations for pulmonary sarcoidosis patients. Panellists reached consensus that asymptomatic patients with normal pulmonary function and adenopathy alone or normal chest imaging do not require therapy, while symptomatic patients with impaired pulmonary function or infiltrates should be treated. The panel did not reach consensus on asymptomatic patients with abnormal chest imaging or reduced pulmonary function, or symptomatic patients with normal chest imaging and pulmonary function. The proposed phenotype categories and associated treatment recommendations are asymptomatic (no therapy), acute (disease duration <1-2 years, apparently self-limited, corticosteroids), chronic (antimetabolites and other second-line therapies) and advanced (biologics). Some clinical settings, such as dyspnoea/hypoxaemia at rest, severely impaired or rapidly decreasing pulmonary function tests, and severe cardiac, neurologic, ocular or renal involvement warrant immediate therapy., Competing Interests: Conflict of interest: R.P.

In patients treated with repository corticotrophin injection (RCI) for pulmonary sarcoidosis, effective management of adverse events may improve adherence. However, management of adverse events may be challenging due to limitations in real-world clinical experience with RCI and available published guidelines.We surveyed 12 physicians with a modified Delphi process using three questionnaires. Questionnaire 1 consisted of open-ended questions. Panellists' answers were developed into a series of statements for Questionnaires 2 and 3. In these, physicians rated their agreement with the statements using a Likert scale.Key consensus recommendations included a starting dose of 40 units twice a week for patients with less severe disease, continued at a maintenance dose for patients who responded, particularly those with chronic refractory sarcoidosis. Panellists reached consensus that concomitant steroids should be quickly tapered in patients receiving RCI, but that concomitant use of immunosuppressive medications should be continued. Panellists developed consensus recommendations for adverse event management, and reached consensus that RCI should be down-titrated or discontinued if other interventions for the adverse effects fail or if the adverse effect is severe.In the absence of clinical evidence, our Delphi consensus opinions may provide practical guidance to physicians on the management of RCI to treat pulmonary sarcoidosis., Competing Interests: Conflict of interest: F.F.

Pulmonary sarcoidosis presents substantial management challenges, with limited evidence on effective therapies and phenotypes. In the absence of definitive evidence, expert consensus can supply clinically useful guidance in medicine. An international panel of 26 experts participated in a Delphi process to identify consensus on pharmacological management in sarcoidosis with the development of preliminary recommendations.The modified Delphi process used three rounds. The first round focused on qualitative data collection with open-ended questions to ensure comprehensive inclusion of expert concepts. Rounds 2 and 3 applied quantitative assessments using an 11-point Likert scale to identify consensus.Key consensus points included glucocorticoids as initial therapy for most patients, with non-biologics (immunomodulators), usually methotrexate, considered in severe or extrapulmonary disease requiring prolonged treatment, or as a steroid-sparing intervention in cases with high risk of steroid toxicity. Biologic therapies might be considered as additive therapy if non-biologics are insufficiently effective or are not tolerated with initial biologic therapy, usually with a tumour necrosis factor-α inhibitor, typically infliximab.The Delphi methodology provided a platform to gain potentially valuable insight and interim guidance while awaiting evidenced-based contributions., Competing Interests: Conflict of interest: F.F.
