RESUMO
BACKGROUND: Clinical presentation and prevalence of organ involvement is highly variable in sarcoidosis and depends on ethnic, genetic and geographical factors. These data are not extensively studied in a Dutch population. AIM: To determine the prevalence of organ involvement and the indication for systemic immunosuppressive therapy in newly diagnosed sarcoidosis patients in the Netherlands. METHODS: Two large Dutch teaching hospitals participated in this prospective cohort study. All adult patients with newly diagnosed sarcoidosis were prospectively included and a standardized work-up was performed. Organ involvement was defined using the WASOG instrument. RESULTS: Between 2015 and 2020, a total of 330 patients were included, 55% were male, mean age was 46 (SD 14) years. Most of them were white (76%). Pulmonary involvement including thoracic lymph node enlargement was present in 316 patients (96%). Pulmonary parenchymal disease was present in 156 patients (47%). Ten patients (3%) had radiological signs of pulmonary fibrosis. Cutaneous sarcoidosis was present in 74 patients (23%). Routine ophthalmological screening revealed uveitis in 29 patients (12%, n = 256)). Cardiac and neurosarcoidosis were diagnosed in respectively five (2%) and six patients (2%). Renal involvement was observed in 11 (3%) patients. Hypercalcaemia and hypercalciuria were observed in 29 (10%) and 48 (26%, n = 182) patients, respectively. Hepatic involvement was found in 6 patients (2%). In 30% of the patients, systemic immunosuppressive treatment was started at diagnosis. CONCLUSIONS: High-risk organ involvement in sarcoidosis is uncommon at diagnosis. Indication for systemic immunosuppressive therapy was present in a minority of patients.

PURPOSE OF REVIEW: In recent years new recommendations have been published about organ assessment in the diagnosis of sarcoidosis. RECENT FINDINGS: Screening for pulmonary, cardiac, ocular, neurologic and renal involvement and hypercalcemia is recommended in the work-up for sarcoidosis, additionally, screening for hypercalciuria at the time of the diagnosis might be beneficial. SUMMARY: One of the goals in the work-up of sarcoidosis is to assess the extent and severity of organ involvement. Timely and accurate assessment leads to determination of treatment indication. Screening for pulmonary involvement should include pulmonary imaging and pulmonary function tests. Screening for cardiac involvement should include a clear history including palpitations and collapse and a baseline electrocardiogram or 24-h Holter monitoring. At diagnosis, ophthalmological assessment is recommended. Furthermore, serum calcium level and serum creatinine level should be obtained. Although routine 24-h urinary calcium excretion is not included in the guidelines, performing this test routinely can be considered. On indication, neurologic, rheumatologic or dermatologic assessment can be performed.

INTRODUCTION: Besides dyspnoea and cough, patients with idiopathic pulmonary fibrosis (IPF) or sarcoidosis may experience distressing non-respiratory symptoms, such as fatigue or muscle weakness. However, whether and to what extent symptom burden differs between patients with IPF or sarcoidosis and individuals without respiratory disease remains currently unknown. OBJECTIVES: To study the respiratory and non-respiratory burden of multiple symptoms in patients with IPF or sarcoidosis and to compare the symptom burden with individuals without impaired spirometric values, FVC and FEV1 (controls). METHODS: Demographics and symptoms were assessed in 59 patients with IPF, 60 patients with sarcoidosis and 118 controls (age ≥18 years). Patients with either condition were matched to controls by sex and age. Severity of 14 symptoms was assessed using a Visual Analogue Scale. RESULTS: 44 patients with IPF (77.3% male; age 70.6±5.5 years) and 44 matched controls, and 45 patients with sarcoidosis (48.9% male; age 58.1±8.6 year) and 45 matched controls were analyzed. Patients with IPF scored higher on 11 symptoms compared to controls (p<0.05), with the largest differences for dyspnoea, cough, fatigue, muscle weakness and insomnia. Patients with sarcoidosis scored higher on all 14 symptoms (p<0.05), with the largest differences for dyspnoea, fatigue, cough, muscle weakness, insomnia, pain, itch, thirst, micturition (night, day). CONCLUSIONS: Generally, respiratory and non-respiratory symptom burden is significantly higher in patients with IPF or sarcoidosis compared to controls. This emphasizes the importance of awareness for respiratory and non-respiratory symptom burden in IPF or sarcoidosis and the need for additional research to study the underlying mechanisms and subsequent interventions.

BACKGROUND: CT Severity Score (CT-SS) can be used to assess the extent of severe coronavirus disease 19 (COVID-19) pneumonia. Follow-up CT-SS in patients surviving COVID-19-associated hyperinflammation and its correlation with respiratory parameters remains unknown. This study aims to assess the association between CT-SS and respiratory outcomes, both in hospital and at three months after hospitalization. METHODS: Patients from the COVID-19 High-intensity Immunosuppression in Cytokine storm Syndrome (CHIC) study surviving hospitalization due to COVID-19 associated hyperinflammation were invited for follow-up assessment at three months after hospitalization. Results of CT-SS three months after hospitalization were compared with CT-SS at hospital admission. CT-SS at admission and at 3-months were correlated with respiratory status during hospitalization and with patient reported outcomes as well as pulmonary- and exercise function tests at 3-months after hospitalization. RESULTS: A total of 113 patients were included. Mean CT-SS decreased by 40.4% (SD 27.6) in three months (P < 0.001). CT-SS during hospitalization was higher in patients requiring more oxygen (P < 0.001). CT-SS at 3-months was higher in patients with more dyspnoea (CT-SS 8.31 (3.98) in patients with modified Medical Council Dyspnoea scale (mMRC) 0-2 vs. 11.03 (4.47) in those with mMRC 3-4). CT-SS at 3-months was also higher in patients with a more impaired pulmonary function (7.4 (3.6) in patients with diffusing capacity for carbon monoxide (DLCO) > 80%pred vs. 14.3 (3.2) in those with DLCO < 40%pred, P = 0.002). CONCLUSION: Patients surviving hospitalization for COVID-19-associated hyperinflammation with higher CT-SS have worse respiratory outcome, both in-hospital and at 3-months after hospitalization. Strict monitoring of patients with high CT-SS is therefore warranted.

BACKGROUND: Diagnosing concomitant pulmonary embolism (PE) in COVID-19 patients remains challenging. As such, PE may be overlooked. We compared the diagnostic yield of systematic PE-screening based on the YEARS-algorithm to PE-screening based on clinical gestalt in emergency department (ED) patients with COVID-19. METHODS: We included all ED patients who were admitted because of COVID-19 between March 2020 and February 2021. Patients already receiving anticoagulant treatment were excluded. Up to April 7, 2020, the decision to perform CT-pulmonary angiography (CTPA) was based on physician's clinical gestalt (clinical gestalt cohort). From April 7 onwards, systematic PE-screening was performed by CTPA if D-dimer level was ≥1000 ug/L, or ≥500 ug/L in case of ≥1 YEARS-item (systematic screening cohort). RESULTS: 1095 ED patients with COVID-19 were admitted. After applying exclusion criteria, 289 were included in the clinical gestalt and 574 in the systematic screening cohort. The number of PE diagnoses was significantly higher in the systematic screening cohort compared to the clinical gestalt cohort: 8.2% vs. 1.0% (3/289 vs. 47/574; p<0.001), even after adjustment for differences in patient characteristics (adjusted OR 8.45 (95%CI 2.61-27.42, p<0.001) for PE diagnosis). In multivariate analysis, D-dimer (OR 1.09 per 1000 µg/L increase, 95%CI 1.06-1.13, p<0.001) and CRP >100 mg/L (OR 2.78, 95%CI 1.37-5.66, p = 0.005) were independently associated with PE. CONCLUSION: In ED patients with COVID-19, the number of PE diagnosis was significantly higher in the cohort that underwent systematic PE screening based on the YEARS-algorithm in comparison with the clinical gestalt cohort, with a number needed to test of 7.1 CTPAs to detect one PE.

Bronchial stenosis is an uncommon but potentially life-threatening complication of granulomatosis with polyangiitis (GPA). The development of lower respiratory tract stenoses in patients with GPA is thought to be the result of persistent inflammation of the cartilaginous tissue. New assessment methods for this severe GPA complication are highly needed. Herein, we show the value of 18F-fluorodeoxyglycose positron emission tomography/computed tomography (18F-FDG-PET/CT) in the diagnosis, prediction of progression to bronchial stenosis and response to treatment of endobronchial involvement in a patient with GPA.

AIMS: We aim to evaluate the clinical pharmacokinetics of a single dose interleukin-6 (IL-6) antibody tocilizumab (TCZ) in methylprednisolone (MP)-treated COVID-19 patients with cytokine storm syndrome (CSS). METHODS: MP pre-treated patients with COVID-19-associated CSS, defined as at least two elevations of C-reactive protein (CRP) >100 mg/L, ferritin >900 µg/L or D-dimers >1500 µg/L, received intravenous TCZ (8 mg/kg, max. 800 mg) upon clinical deterioration. A nonlinear-mixed effects model was developed based on TCZ serum concentrations and dosing information. Population pharmacokinetic parameters were estimated and concentration-time profiles were plotted against individual predicted values. Fixed dose simulations were subsequently performed based on the final model. RESULTS: In total 40 patients (mean [SD] age: 62 [12] years, 20% female, body weight: 87 [17] kg) with COVID-19 induced CSS were evaluated on pharmacokinetics and laboratory parameters. A biphasic elimination of TCZ serum concentration was described by a homogeneous population pharmacokinetic model. Serum TCZ concentrations above the 1 µg/L target saturation threshold were covered for 16 days in all evaluated patients treated with a single dose of 8 mg/kg. In a simulation with TCZ 400 mg fixed dose, this condition of full IL-6 receptor occupancy at minimum serum concentration was also met. CONCLUSIONS: A single dose (8 mg/kg, max. 800 mg) is sufficient to cover a period of 16 days of IL-6-mediated hyperinflammation in COVID-19-induced CSS in MP-treated patients. Based on body weight PK simulations, a fixed-dose tocilizumab of 400 mg should be considered to prevent overtreatment, future drug shortage and unnecessary drug expenditure.
RESUMO
BACKGROUND: Sarcoidosis-associated fatigue is highly prevalent and is often reported as the most burdensome symptom of sarcoidosis. Management of fatigue is challenging, and evidence-based therapies are lacking. In this TIRED trial, we aimed to assess the effects of a 12-week online mindfulness-based cognitive therapy (eMBCT) on fatigue. METHODS: This study was a prospective, open-label, multicentre randomised controlled trial, conducted at three centres in the Netherlands. Eligible patients were 18 years or older, had stable sarcoidosis, and a score of more than 21 points on the Fatigue Assessment Scale (FAS). Patients were randomised into either the eMBCT or the control group. Participants completed patient-reported outcome measures at baseline, after intervention (T1), and 12 weeks after completion of eMBCT (T2). The primary outcome was the change in FAS score at T1 in the eMBCT group compared with the control group, assessed with the independent students't test in all patients who started the study. Secondary outcomes included within-group difference in FAS score at T1 and T2, between-group difference in FAS score at T2, and changes in the Hospital Anxiety and Depression Scale, the Freiburg Mindfulness Inventory-Short Form, and the Kings Sarcoidosis Questionnaire. The study was registered at the Netherlands Trial Register, NL7816. FINDINGS: Between June 5, 2019, and Oct 28, 2021, 99 patients were randomly assigned to the eMBCT (n=52) or the control (n=47) groups. Six patients withdrew consent after psychological screening before the start of eMBCT. Baseline FAS score was similar in both groups (34·57 [SD 6·07] for 46 patients in the eMBCT group and 35·51 [4·65] for 47 patients in the control group). Mean change in FAS score at T1 was -4·53 (SD 5·77; p<0·0001) in the eMBCT group and -1·28 (3·80; p=0·026) in the control group (between-group difference 3·26 [95% CI 1·18 to 5·33; p=0·0025]). Furthermore, the eMBCT group had a significant improvement in anxiety (mean between-group difference 1·69, 95% CI 0·22-3·16; p=0·025), depressive symptoms (1·52, 0·08-2·95; p=0·039), mindfulness (3·1, 0·70-5·49; p=0·022), and general health status (6·28, 2·51-10·06; p=0·002) at T1, compared with the control group. INTERPRETATION: 12 week eMBCT improves fatigue, anxiety, depression, mindfulness, and health status in patients with sarcoidosis-associated fatigue.

Introduction: Pulmonary embolism (PE) is a frequent complication in COVID-19. However, the influence of PE on the prognosis of COVID-19 remains unclear as previous studies were affected by misclassification bias. Therefore, we evaluated a cohort of COVID-19 patients whom all underwent systematic screening for PE (thereby avoiding misclassification) and compared clinical outcomes between patients with and without PE. Materials and methods: We included all COVID-19 patients who were admitted through the ED between April 2020 and February 2021. All patients underwent systematic work-up for PE in the ED using the YEARS-algorithm. The primary outcome was a composite of in-hospital mortality and ICU admission. We also evaluated long-term outcomes including PE occurrence within 90 days after discharge and one-year all-cause mortality. Results: 637 ED patients were included in the analysis. PE was diagnosed in 46 of them (7.2%). The occurrence of the primary outcome did not differ between patients with PE and those without (28.3% vs. 26.9%, p = 0.68). The overall rate of PE diagnosed in-hospital (after an initial negative PE screening in the ED) and in the first 90 days after discharge was 3.9% and 1.2% respectively. One-year all-cause mortality was similar between patients with and without PE (26.1% vs. 24.4%, p = 0.83). Conclusions: In a cohort of COVID-19 patients who underwent systematic PE screening in the ED, we found no differences in mortality rate and ICU admissions between patients with and without PE. This may indicate that proactive PE screening, and thus timely diagnosis and treatment of PE, may limit further clinical deterioration and associated mortality in COVID-19 patients.
RESUMO
Background: Chronic granulomatous disease (CGD) is a rare immunodeficiency disorder resulting in phagocytic cell dysfunction. It is characterized by deficient cellular immunity against bacteria and fungi, and an excessive inflammatory response resulting in granuloma formation. It manifests, usually in early childhood, with recurrent bacterial and fungal infections or inflammatory complications. The infections, such as invasive pulmonary aspergillosis, can be life-threatening. Case description: Our patient was a 40-year-old man with no pulmonary history who presented with bilateral pulmonary nodules and pronounced eosinophilia in peripheral blood and bronchoalveolar lavage fluid, mimicking eosinophilic pneumonia. During treatment with corticosteroids, the patient deteriorated clinically and radiographically. Extensive investigations failed to provide a diagnosis. A lung biopsy demonstrated the presence of granulomas and Aspergillus fumigatus hyphae. Advanced screening to detect underlying immunodeficiency revealed CGD. Discussion: This case report describes a unique first presentation of CGD. It reminds physicians of the possibility of CGD as an underlying immune disorder in invasive aspergillosis and highlights the challenges of diagnosing invasive pulmonary aspergillosis. We discuss the diagnostic pitfalls of this case and propose a diagnostic work-up for eosinophilic lung disease. LEARNING POINTS: Pulmonary aspergillosis can present as eosinophilic pneumonia and should be included in the differential diagnosis of eosinophilic lung disease.In case of invasive pulmonary aspergillosis, investigation for chronic granulomatous disease should be considered.Chronic granulomatous disease in adults is probably underdiagnosed because of its variable clinical presentations.
RESUMO
BACKGROUND: Pirfenidone slows down disease progression in idiopathic pulmonary fibrosis (IPF). Recent studies suggest a treatment effect in progressive pulmonary fibrosis other than IPF. However, the safety and effectiveness of pirfenidone in asbestosis patients remain unclear. In this study, we aimed to investigate the safety, tolerability and efficacy of pirfenidone in asbestosis patients with a progressive phenotype. METHODS: This was a multicenter prospective study in asbestosis patients with progressive lung function decline. After a 12-week observational period, patients were treated with pirfenidone 801 mg three times a day. Symptoms and adverse events were evaluated weekly and patients completed online patient-reported outcomes measures. At baseline, start of therapy, 12 and 24 weeks, in hospital measurement of lung function and a 6 min walking test were performed. Additionally, patients performed daily home spirometry measurements. RESULTS: In total, 10 patients were included of whom 6 patients (66.7%) experienced any adverse events during the study period. Most frequently reported adverse events were fatigue, rash, anorexia and cough, which mostly occurred intermittently and were reported as not very bothersome. No significant changes in hospital pulmonary function (forced vital capacity (FVC), diffusion capacity of the lung for carbon monoxide (DLCO), 6 min walking test or patient-reported outcomes measures before and after start of pirfenidone were found. Home spirometry demonstrated a FVC decline in 12 weeks before start of pirfenidone, while FVC did not decline during the 24 week treatment phase, but this difference was not statistically significant. CONCLUSIONS: Treatment with pirfenidone in asbestosis has an acceptable safety and tolerability profile and home spirometry data suggest this antifibrotic treatment might attenuate FVC decline in progressive asbestosis. Trial registration MEC-2018-1392; EudraCT number: 2018-001781-41.

BACKGROUND: COVID-19 is an ongoing pandemic leading to exhaustion of the hospital care system. Our health care system has to deal with a high level of sick leave of health care workers (HCWs) with COVID-19 related complaints, in whom an infection with SARS-CoV-2 has to be ruled out before they can return back to work. The aim of the present study is to investigate if the recently described CoLab-algorithm can be used to exclude COVID-19 in a screening setting of HCWs. METHODS: In the period from January 2021 till March 2021, HCWs with COVID-19-related complaints were prospectively collected and included in this study. Next to the routinely performed SARS-CoV-2 RT-PCR, using a set of naso- and oropharyngeal swab samples, two blood tubes (one EDTA- and one heparin-tube) were drawn for analysing the 10 laboratory parameters required for running the CoLab-algorithm. RESULTS: In total, 726 HCWs with a complete CoLab-laboratory panel were included in this study. In this group, 684 HCWs were tested SARS-CoV-2 RT-PCR negative and 42 cases RT-PCR positive. ROC curve analysis showed an area under the curve (AUC) of 0.853 (95% CI: 0.801-0.904). At a safe cut-off value for excluding COVID-19 of -6.525, the sensitivity was 100% with a specificity of 34% (95% CI: 21 to 49%). No SARS-CoV-2 RT-PCR cases were missed with this cut-off and COVID-19 could be safely ruled out in more than one third of HCWs. CONCLUSION: The CoLab-score is an easy and reliable algorithm that can be used for screening HCWs with COVID-19 related complaints. A major advantage of this approach is that the results of the score are available within 1 hour after collecting the samples. This results in a faster return to labour process of a large part of the COVID-19 negative HCWs (34%), next to a reduction in RT-PCR tests (reagents and labour costs) that can be saved.
