Semin Arthritis Rheum 2024; 65:152352. [PMID: 38185078 DOI: 10.1016/j.semarthrit.2023.152352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/15/2023] [Accepted: 12/08/2023] [Indexed: 01/09/2024]
Abstract
OBJECTIVE To depict the clinical panorama of spontaneous pneumomediastinum (SPM) in anti-MDA5 antibody-positive dermatomyositis (anti-MDA5+ DM). METHODS A total of 1352 patients with idiopathic inflammatory myopathy (IIM), including 384 anti-MDA5+ DM patients were retrospectively enrolled. The clinical profiles of anti-MDA5+ DM-associated SPM were analyzed. RESULTS We identified that 9.4 % (36/384) of anti-MDA5+ DM patients were complicated with SPM, which was significantly higher than that of non-anti-MDA5+ DM and other IIM subtypes (P all <0.001). SPM developed at a median of 5.5 (3.0, 12.0) months after anti-MDA5+ DM onset. Anti-MDA5+ DM patients complicated with SPM showed a significantly higher frequency of fever, dyspnea, and pulmonary infection including viral and fungal infections compared to those without SPM (P all < 0.05). Cytomegalovirus (CMV) and fungal infections were identified to be independent risk factors for SPM development in the anti-MDA5+ DM. SPM and non-SPM patients in our anti-MDA5+ DM cohort showed comparable short-term and long-term survival (P = 0.236). Furthermore, in the SPM group, we found that the non-survivors had a lower peripheral lymphocyte count, higher LDH level, and higher frequency of intensification of immunosuppressive treatment (IST) than survivors. The elevated LDH level and intensification of IST were independent risk factors for increased mortality in anti-MDA5+ DM-associated SPM patients. CONCLUSIONS Nearly one-tenth of patients with anti-MDA5+ DM develop SPM. Both CMV and fungal infections are risk factors for SPM occurrence. The development of SPM does not worsen the prognosis of anti-MDA5+ DM patients, and the intensification of IST does harm to the SPM prognosis.

Abstract
A 50-year-old woman with a history of systemic lupus erythematosus and a recent infection with COVID-19 presented to the emergency department with acute shortness of breath twice in 10 days. She was diagnosed with myopericarditis attributed to COVID-19 infection (first admission), and chest X-ray revealed a small left-sided pneumothorax, pericardial effusion (second admission), with no mediastinal shift or other signs of tension. Computed tomography confirmed these results and revealed a few small cysts in the right lung. An echocardiogram demonstrated normal heart anatomy and filling dynamics. The patient was diagnosed with simple pneumothorax and ongoing myopericarditis managed with colchicine, ibuprofen, and low-dose prednisolone. The patient responded to treatment and was discharged. Pneumothorax association with COVID-19 is reported in a small number of publications, but the association is less clear with SLE. Our patient may have been predisposed to developing pneumothorax after COVID-19 infection due to her existing connective tissue disorder.

Abstract
Objective To identify factors associated with pneumomediastinum during management of connective tissue disease (CTD)-related interstitial lung disease (ILD). Methods Patients diagnosed with pneumomediastinum after the initiation of corticosteroid therapy for their CTD-ILD were enrolled. The baseline characteristics of patients who developed pneumomediastinum after the initiation of corticosteroid therapy (n=13, all occurring within 120 days) were compared to those of patients who did not develop pneumomediastinum (n=49). A multivariate logistic regression analysis was performed to identify factors associated with pneumomediastinum. A receiver operating characteristic (ROC) curve analysis was also performed to assess the predictive performance. Results The body mass index (BMI) [odds ratio (OR) (95% confidence interval (CI)) 0.482 (0.272-0.853)] and serum lactate dehydrogenase (LDH) [OR (95% CI) 1.013 (1-1.025)] levels at baseline were identified as independent factors associated with pneumomediastinum after corticosteroid initiation. The optimal cut-off points of the BMI and LDH levels for predicting pneumomediastinum development, as estimated by the Youden index, were 20.2 kg/m2 and 378 U/L, respectively. LDH showed a sensitivity of 61.5% and the highest specificity of 87.8%. Importantly, combining these markers resulted in the highest sensitivity of 100% and a specificity of 71.4%. Conclusion A low BMI and high serum LDH levels at baseline are useful predictive factors for pneumomediastinum development in CTD-ILD patients.

Abstract
A 38-year-old hypertensive male with a smoking history presented to the emergency room with significant hemoptysis, arthritis, and a purpuric rash. Other findings included a dropping hemoglobin and acute kidney injury with microscopic hematuria. The pulmonary computed tomography was significant for alveolar hemorrhage and a rarely reported pneumomediastinum. Along with this constellation of findings, a positive antiproteinase 3 helped to confirm this patient's diagnosis of granulomatosis with polyangiitis. Treatment commenced with sessions of plasma exchange and pulse steroids along with cyclophosphamide infusions. The patient had since improved and made a full recovery. This case report highlights the rarely described pneumomediastinum in association with vasculitides.

Abstract
BACKGROUND Spontaneous pneumomediastinum (SP) is an uncommon disorder but has been described in cases with connective tissue diseases (CTDs), most commonly dermatomyositis and polymyositis. We aimed to explore this relationship by analyzing the characteristics of CTD patients with SP. METHODS Using a computer-assisted search, we identified 25 patients with CTD and SP evaluated between January 1997 and December 2016 at our institution. Clinicoradiologic characteristics, treatment, and outcomes were extracted and chest computed tomography studies analyzed. RESULTS We identified 25 patients with CTD and SP. Median (range) age at SP occurrence was 55 (18-82) years, and 60% of the patients were women. Smoking history was present in 37%. Spontaneous pneumomediastinum was symptomatic in 56% of patients. Eighteen patients (72%) had a known CTD diagnosis, and 20 patients (80%) manifested radiologic evidence of interstitial lung disease. Spontaneous pneumomediastinum diagnosis was achieved with chest radiography in 20% of cases and chest computed tomography in the other cases. Spontaneous pneumomediastinum was managed with expectant observation alone in 22 cases (88%). Four patients (16%) had concomitant pneumothorax, 1 of whom required chest tube drainage. There were no deaths attributable to SP during the median (range) follow-up of 13 (0-174) months. Cumulative survival was 52% at 1 year and 40% at 2 years. CONCLUSIONS Spontaneous pneumomediastinum is an uncommon manifestation of CTD and usually occurs in the presence of interstitial lung disease. Although SP seems to be associated with a relatively benign short-term course, occurrence of SP in CTD patients may be a poor prognostic factor.

Abstract
Subacute-acute, hyperacute, or even catastrophic and fulminant respiratory events occur in almost all classic connective tissue disorders (CTDs); they may share systemic life-threatening manifestations, may precipitously lead to respiratory failure requiring ventilatory support as well as a combination of specific therapeutic measures, and in most affected patients constitute the devastating end-of-life event. In CTDs, acute respiratory events may be related to any respiratory compartment including the airways, lung parenchyma, alveolar capillaries, lung vessels, pleura, and ventilatory muscles. Acute respiratory events may also precipitate disease-specific extrapulmonary organ involvement such as aspiration pneumonia and lead to digestive tract involvement and heart-related respiratory events. Finally, antirheumatic drug-related acute respiratory toxicity as well as lung infections related to the rheumatic disease and/or to immunosuppression complete the spectrum of acute respiratory events. Overall, in CTDs the lungs significantly contribute to morbidity and mortality, since they constitute a common site of disease involvement; a major site of infections related to the 'mater' disease; a major site of drug-related toxicity, and a common site of treatment-related infectious complications. The extreme spectrum of the abovementioned events, as well as the 'vicious' coexistence of most of the aforementioned manifestations, requires skills, specific diagnostic and therapeutic means, and most of all a multidisciplinary approach of adequately prepared and expert scientists. Avoiding lung disease might represent a major concern for future advancements in the treatment of autoimmune disorders.

Abstract
A 73-year-old woman was diagnosed with interstitial pneumonia in 2006; however, the disease was not progressive. Four years later, purpura, peripheral neuropathy, and increased levels of myeloperoxidase anti-neutrophil cytoplasmic antibodies (583 EU/mL) and C-reactive protein (2.27 mg/dL) were observed, and a diagnosis of microscopic polyangiitis was made. Treatment with prednisolone and azathioprine was initiated. However, on the 35th hospital day, chest computed tomography showed pneumomediastinum and subcutaneous emphysema without aggravation of the interstitial pneumonia. To our knowledge, this is the first report of pneumomediastinum as a complication of microscopic polyangiitis associated with interstitial pneumonia.

Abstract
Pneumomediastinum has been described as a rare complication of connective tissue diseases. Here, we report four cases of pneumomediastinum: three of which are associated with dermatomyositis and one with mixed connective tissue disease. All our patients had interstitial lung disease. The first case of dermatomyositis described below was complicated by epidural emphysema (pneumorrhachis) in addition to pneumomediastinum. Pneumorrhachis is reported in many isolated case reports and series in the setting of asthma, pneumothorax, blunt chest trauma, etc. Less than 10% of pneumomediastinum cases develop this complication and vast majority of cases resolve spontaneously. The mechanism behind this has been postulated to be the passage of air through the intervertebral foramen. Others suggest entrapment of air which dissects between paraspinal soft tissues and along the vascular and nerve sheaths into the epidural space. This is the first ever reported case of epidural emphysema in connective tissue disease to the best of our knowledge.

Abstract
Pneumothorax is a rare pleuropulmonary manifestation of systemic lupus erythematosus. We encountered a 37-year-old Japanese woman who had systemic lupus erythematosus complicated by recurrent pneumothorax during treatment for recurrent serositis with glucocorticoid therapy. She was admitted for the third episode of lupus peritonitis in December 2005. Intravenous cyclophoshamide and increased dose of oral prednisolone were administered. In early January 2006, hemoptysis was observed and bronchofiberscopy revealed hemorrhage from the left lower lobe. After intravenous methylprednisolone pulse therapy and oral cyclosporine therapy were added, pleurisy and pulmonary hemorrhage improved. On February 22nd, she suddenly developed pneumothorax on the right side, followed by pneumothorax on the left side after 2 days. This pneumothorax on the left side did not improve despite chest tube drainage for over one month. She underwent thoracoscopic partial lobectomy of lower lobe of the left lung, and her symptoms improved. Review of the literature identified 10 case reports of systemic lupus erythematosus complicated by pneumothorax. All of the patients including our case had underlying pulmonary lesions, and 9/11 patients had pleurisy. Besides 10/11 patients received glucocorticoid therapy before the occurrence of pneumothorax. Tissue fragility caused by these factors might contribute to the complication of pneumothorax in patients with systemic lupus erythematosus.

Abstract
We report a case of a 29-year-old woman who is known to have systemic lupus erythematosus and idiopathic interstitial pneumonia; she presented with a 1-day history of substernal chest pain and increasing shortness of breath. On examination, she was found breathless, but was not distressed or afebrile or normotensive. Auscultation of the heart revealed a positive Hamman's sign. There was chest-wall crepitus, and auscultation of the lung showed bilateral crepitations. Full blood count and biochemical profile were unremarkable. Chest x-ray showed signs of idiopathic interstitial pneumonia in addition to pneumomediastinum (linear band of air within mediastinal planes and continuous diaphragm sign) and chest-wall subcutaneous emphysema. She was treated with high-concentration oxygen. A repeat chest x-ray 5 days later showed complete resolution of the pneumomediastinum and subcutaneous emphysema, but signs of idiopathic interstitial pneumonia continued to persist.

Abstract
We present a case of persistent spontaneous pneumomediastinum precipitated by an upper respiratory infection in a patient with interstitial fibrosis associated with rheumatoid arthritis who was receiving chronic corticosteroid treatment. The persistent nature of the mediastinal emphysema over 2 months eventually required treatment with high concentrations of inhaled oxygen that resulted in rapid resolution of the pneumomediastinum without recurrence over 6 months of follow-up. This case, along with others in the medical literature, emphasizes the need for early use of high-concentration inhaled oxygen in the treatment of pneumomediastinum in high-risk patients, such as those with connective tissue disorders.
