Abstract
The use of pulmonary function tests (PFTs) has been widely described in airway diseases like asthma and cystic fibrosis, but for children's interstitial lung disease (chILD), which encompasses a broad spectrum of pathologies, the usefulness of PFTs is still undetermined, despite widespread use in adult interstitial lung disease. A literature review was initiated by the COST/Enter chILD working group aiming to describe published studies, to identify gaps in knowledge and to propose future research goals in regard to spirometry, whole-body plethysmography, infant and pre-school PFTs, measurement of diffusing capacity, multiple breath washout and cardiopulmonary exercise tests in chILD. The search revealed a limited number of papers published in the past three decades, of which the majority were descriptive and did not report pulmonary function as the main outcome.PFTs may be useful in different stages of management of children with suspected or confirmed chILD, but the chILD spectrum is diverse and includes a heterogeneous patient group in all ages. Research studies in well-defined patient cohorts are needed to establish which PFT and outcomes are most relevant for diagnosis, evaluation of disease severity and course, and monitoring individual conditions both for improvement in clinical care and as end-points in future randomised controlled trials.

Pediatr Pulmonol 2017; 52:1335-1339.

Abstract
AIM To determine the association among fractional exhaled nitric oxide (FENO), pulmonary function, and disease activity in children with systemic lupus erythematosus (SLE). METHODS Children aged 7-18 years, diagnosed with SLE under the criteria of the American Rheumatism Association (revised 2012), were enrolled. All eligible participants had disease activity, FENO, and pulmonary function evaluated and re-evaluated at 6-month follow-up. RESULTS Twenty-four children (95.8% female; mean age 15.2 ± 2 years; median disease duration 2.4 years) were studied. The mean FENO1 and FENO2 were 19.6 ± 7.2 parts per billion (ppb) and 17.4 ± 4.5 ppb, respectively. At baseline, 20.8% had abnormal pulmonary functions (all restrictive defects) and increased to 29.2% at follow-up (isolated restrictive defect 25% and restrictive with diffusion defect 4.2%). Most of their disease activities at baseline and second assessment were non-active (58.3%, 70.8%) or mild disease activities (20.8% both). There was significant correlation between FENO and disease activity (r = 0.49; P-value = 0.02). The significant negative correlation between total lung capacity (TLC) and disease activity was detected in children with active SLE (r = -0.71; P-value = 0.02). CONCLUSION Decreased TLC and high FENO were common in SLE children who had no respiratory symptoms and correlated with disease activity. FENO should be considered as an additional pulmonary function to evaluate disease activity in children with SLE.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) is a rare, multisystem and potentially life-threatening autoimmune disorder with significant associated morbidity. Evidence-based guidelines are sparse and management is often based on clinical expertise. SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) was launched to optimise and disseminate management regimens for children and young adults with rheumatic diseases like cSLE. Here, we provide evidence-based recommendations for diagnosis and treatment of cSLE. In view of extent and complexity of cSLE and its various manifestations, recommendations for lupus nephritis and antiphospholipid syndrome will be published separately. Recommendations were generated using the EULAR (European League Against Rheumatism) standard operating procedure. An expert committee consisting of paediatric rheumatologists and representation of paediatric nephrology from across Europe discussed evidence-based recommendations during two consensus meetings. Recommendations were accepted if >80% agreement was reached. A total of 25 recommendations regarding key approaches to diagnosis and treatment of cSLE were made. The recommendations include 11 on diagnosis, 9 on disease monitoring and 5 on general treatment. Topics included: appropriate use of SLE classification criteria, disease activity and damage indices; adequate assessment of autoantibody profiles; secondary macrophage activation syndrome; use of hydroxychloroquine and corticosteroid-sparing regimens; and the importance of addressing poor adherence. Ten recommendations were accepted regarding general diagnostic strategies and treatment indications of neuropsychiatric cSLE. The SHARE recommendations for cSLE and neuropsychiatric manifestations of cSLE have been formulated by an evidence-based consensus process to support uniform, high-quality standards of care for children with cSLE.

Abstract
Pleuropulmonary manifestations of rheumatological diseases are rare in children but pose a significant risk to overall morbidity and mortality. We have reviewed the literature to provide an overview of the respiratory complications of the commonest rheumatological diseases to occur in children (juvenile systemic lupus erythematosus, scleroderma, juvenile dermatomyositis, mixed connective tissue disease, granulomatosis with polyangitis and juvenile idiopathic arthritis). Pulmonary function testing in these patients can be used to refine the differential diagnosis and establish disease severity, but also has a role in ongoing monitoring for respiratory complications. Early detection of pulmonary involvement allows for prompt and targeted therapies to achieve the best outcome for the child. This is best achieved with joint specialist paediatric rheumatology and respiratory reviews in a multidisciplinary setting.

Abstract
Cardio-pulmonary manifestations of systemic lupus erythematosus (SLE) are well recognized in adults. We report the occurrence of clinically significant cardio-pulmonary disease in a cohort of predominantly Caucasian children with SLE. All children with SLE attending the Royal Liverpool Children’s NHS Trust between 1995 and 2003 were reviewed. Of 29 children with SLE, 27 (93%) were Caucasian. Nine (31%) had cardio-respiratory complications: cardiac only (n = 1); respiratory only (n = 4); both cardiac and respiratory manifestations (n = 4). Median (range) duration of follow-up of affected children: four years (six months to 11 years). Six out of eight (75%) presented with respiratory complications before SLE was diagnosed. Three children had pericardial effusions, one requiring pericardiocentesis for tamponade. One had cardiac conduction defects and another significant pulmonary hypertension. Respiratory complications comprised: interstitial lung disease (n = 4), with two showing evidence of pulmonary fibrosis; pleural effusions (n = 2), pulmonary haemorrhage (n = 1) and lupus pneumonitis (n = 1). Disease course was complicated by CMV infection in one child. Lung biopsy was performed in five cases. Seven were treated with cyclophosphamide with significant improvement in symptoms/lung function. Of this predominantly Caucasian paediatric cohort with SLE, 31% had significant cardio-pulmonary involvement. All children with SLE should have regular monitoring of their cardio-respiratory status.

Abstract
Objective The aims of this study were to analyze the pulmonary function of childhood-onset systemic lupus erythematosus (cSLE) patients and to identify possible correlations between the high-resolution computed chest tomography (HRCT) score, disease activity, disease cumulative damage, and the participants’ quality of life. Methods Forty cSLE patients, median age: 14.1 years (range: 7.4–17.9), underwent spirometry and plethysmography. Carbon monoxide diffusing capacity (DLCO), HRCT, disease activity, disease cumulative damage, and quality of life were assessed. Results Pulmonary abnormalities were evident in 19/40 (47.5%) cSLE patients according to spirometry/DLCO. Forced expired volume in one second (FEV1%) was the parameter most affected (30%). The HRCT showed some abnormality in 22/30 patients (73%), which were minimal in 43%. Signs of airway affects were found in 50%. Twelve patients were hospitalized due to cSLE-related pulmonary complications before the study began (median discharge: 2.1 years earlier). Total lung capacity (TLC%), vital capacity (VC%), forced vital capacity (FVC%), and FEV1% were significantly lower in the group with hospitalization compared to the group without hospitalization ( p = 0.0025, p = 0.0022, p = 0.0032, and p = 0.0004, respectively). Of note, DLCO was positively correlated with disease duration ( r = +0.4; p = 0.01). The HRCT-score was negatively correlated with FEV1/VC ( r = −0.63; p = 0.0002), FEV1 ( r = −0.54; p = 0.018), FEF25%–75% ( r = −0.67; p < 0.0001), and HRCT-score was positively correlated with resistance ( r = +0.49; p = 0.0056). Conclusions Almost half of patients with cSLE had subclinical pulmonary abnormalities, especially airway abnormalities. The cSLE-related pulmonary complications seem to determine long-term functional damage.

Abstract
OBJECTIVES The aim of this study was to investigate the frequency of pulmonary function abnormalities in clinically asymptomatic children with Systemic Lupus Erythematosus and to determine the relationship of these abnormalities to clinical, laboratory, and immunological parameters as well as to disease activity. METHODS Forty-two children with childhood onset Systemic Lupus Erythematosus were included in this study. Demographic, clinical, laboratory and immunological parameters, as well as disease activity were assessed. Pulmonary function tests (PFT) were performed routinely to screen for subclinical lung disease. RESULTS Out of the 42 children, 19% (n=8) had clinical evidence of pulmonary involvement. The patients with no clinical evidence of pulmonary involvement (n=34) represent the study cohort. From our cohort of patients with no clinical evidence of pulmonary involvement 79% (n=27) had PFT abnormality; including 62% (n=21) had reduced FVC, 71% (n=24) had reduced FEV1, and 67% (n=12) had reduced DLCO. Similarly, 56% (n=15) had a restrictive PFT pattern, and 2.6% (n=2) had an obstructive PFT pattern, while 33% (n=7) had an isolated impairment of diffusion capacity. Due to small sample size; it was not possible to find a statistically significant difference between the cohort of asymptomatic SLE patients with abnormal PFT findings (n=27) and those with normal PFT findings (n=7) in terms of clinical, laboratory, immunological or disease activity index score. CONCLUSION Subclinical lung disease, as demonstrated by abnormal PFT in patients with normal radiographs, may be common but should be interpreted with caution as an early sign of lung disease. Although PFT studies do not correlate well with pulmonary symptoms in patients with childhood onset SLE, they nevertheless provide objective quantification of the type and severity of the functional lesions.

Abstract
AIM To report the prevalence and reversibility of pulmonary function test (PFT) abnormalities among systemic lupus erythematosus (SLE) patients, refractory to therapy, undergoing hematopoietic stem cell transplantation (HSCT). METHODS Thirty-four SLE patients received 200 mg/kg cyclophosphamide and 90 mg/kg equine antithymocyte globulin followed by HSCT. PFTs were performed prior to, at 6 months, and yearly following HSCT. RESULTS The prevalence of significant PFT abnormalities was high (97%). Low FEV(1) and FVC occurred in 26 of 34 patients (76%). A significant abnormality in diffusion capacity of the lung for carbon monoxide (Dlco) occurred in 26 of 32 individuals able to complete Dlco testing (81%). Dlco <or= 50% of predicted occurred in 18 of 32 patients (56%). Of these 18 patients, 4 had no thoracic diagnosis and 7 had no pulmonary diagnosis. For 3 of 11 patients with a Dlco <or= 50% of predicted and a prior pulmonary diagnosis, the only diagnosis had been pleurisy. Ten of the 34 patients (29%) identified the lung as a target organ of the lupus and carried a pulmonary diagnosis, as indicated in Table 1 . Three patients had acute alveolar hemorrhage, four patients had acute lupus pneumonitis, two patients had shrinking lung syndrome (SLS), and one patient had SLE-related pulmonary hypertension. Of these 10 patients, 4 had received prior mechanical ventilation, and 7 had required home supplemental inspired oxygen. Patients have been monitored <or= 77 months, and 28 patients have been monitored > 18 months after HSCT. Five of 28 patients had a normal entry FVC; for each, the FVC remains normal. Of the 23 patients with an abnormal baseline FVC, 18 have improved, 15 completely and 3 partially. Eight of these 18 patients also have improved Dlco. The two patients with a diagnosis of SLS and one patient with SLE-related pulmonary hypertension improved in both parameters. Only 5 of 23 patients with an abnormal FVC did not improve. Each of these five patients retained active lupus in spite of HSCT. CONCLUSION The prevalence of lung impairment among SLE patients requiring long-term immune suppression is high. Following HSCT, pulmonary impairments can improve, which is sustained if disease control is sustained.

Abstract
The aim of this paper was to investigate the frequency of echocardiography (ECHO) and pulmonary function test (PFT) abnormalities in childhood onset systemic lupus erythematosus (SLE), and to determine the relationship of these abnormalities to disease activity. The charts of 50 patients with childhood onset SLE attending a pediatric rheumatology clinic were reviewed for ECHO and PFT studies. The frequency and description of ECHO and PFT abnormalities were documented. Possible associations of PFT and ECHO abnormalities with clinical cardiopulmonary disease, radiographic findings, and measures of lupus disease activity were evaluated. Forty patients (80%) had at least one ECHO study. Twenty-seven (68%) had an abnormal initial study. Nine of 14 patients with an initial abnormal ECHO had normal findings on repeated study. Three abnormalities were considered moderately severe. Thirty-three patients (66%) had at least one PFT performed. Sixteen (48%) were abnormal initially. Four of these 'abnormal' studies were repeated and the abnormalities persisted. Nine patients (27%) were considered to have a severe abnormality. Thirty-one children (62%) had both studies performed. An initial abnormal ECHO and abnormal PFT was found in 10 (32%) of these children. No relationship between ECHO or PFT abnormality and any measure of disease activity (physician's global assessment, anti DNA, C3 or ESR) could be found. Occult cardiac and pulmonary disease as demonstrated by ECHO or PFT occurs frequently in childhood onset SLE. If we wish to understand the natural history of these abnormal heart and lung findings, it will be necessary to do serial testing with ECHO and PFTs in this population.

Abstract
Pleuro-pulmonary involvement has been well recognized in adults affected with systemic lupus erythematosus (SLE), but few studies have been carried out in children. A longitudinal study on a group of 15 children affected with juvenile SLE (JSLE), asymptomatic for lung disease, was performed, and the prevalence and the features of respiratory function alterations, over a period of 12 months, were analysed. Moreover, a possible correlation between any pulmonary function test (PFT) and disease duration, disease activity, visceral involvement and immunological pattern was evaluated. At baseline, a significant functional lung impairment was present in 40% of patients, with a significantly reduced FVC, VA and DLCO in 26% of them; in 60% of patients at 6 months and in 33% of patients at 12 months. At 6 and 12 months, our data did not show any significant modification in PFTs and the restrictive pattern, observed at baseline, remained unchanged. No correlation between altered PFTs and disease duration, activity and/or immunological findings was found. At baseline, the presence of neurological involvement was the only extra-pulmonary feature correlated to reduced FVC.
