RESUMO
INTRODUCTION: Fibrosing mediastinitis (FM) is a rare disease characterized by excessive proliferation of fibrous tissue in the mediastinum and can cause bronchial stenosis, superior vena cava obstruction, pulmonary artery and vein stenosis, etc. CASE PRESENTATION: An aging patient with intermittent chest tightness and shortness of breath was diagnosed with FM associated pulmonary hypertension (FM-PH) by echocardiography and enhanced CT of the chest, and CT pulmonary artery (PA)/ pulmonary vein (PV) imaging revealed PA and PV stenosis. Selective angiography revealed complete occlusion of the right upper PV, and we performed endovascular intervention of the total occluded PV. After failure of the antegrade approach, the angiogram revealed well-developed collaterals of the occluded RSPV-V2b, so we chose to proceed via the retrograde approach. We successfully opened the occluded right upper PV and implanted a stent. CONCLUSIONS: This report may provide new management ideas for the interventional treatment of PV occlusion.

Accessory cardiac bronchus (ACB) is a rare congenital anomaly mainly located in the medial wall of the intermediate bronchus. This anomaly can present with dyspnea, recurrent infections, and hemoptysis. It usually has a blind ending, which may have an impact on airflow patterns and lobar distribution regardless of its diameter and depth. There have been very few cases with ACB. However, the airflow pattern and lobar distribution have not been well studied. In our case with ACB, the proportion of airflow in the right lung was higher than in the model without ACB, while mean airflow velocities were similar in both models. In this regard, quantitative lung ventilation scintigraphy could be better than the anatomical formula in predicting postoperative forced expiratory volume 1 in patients with accessory cardiac bronchus who will undergo lung resection.

Ocrelizumab is an anti-CD20 monoclonal antibody used in the treatment of primary progressive and relapsing multiple sclerosis (MS). Although cases of organizing pneumonia have been reported in association with other antiCD20 agents such as rituximab, there is insufficient data in the literature on Ocrelizumab-associated lung involvement. Herein, we present a case of organizing pneumonia in a 37-year-old female patient with multiple sclerosis following Ocrelizumab use.

Interstitial lung disease (ILD) is one of the common extra-articular manifestations of rheumatoid arthritis (RA) and it is associated with high mortality rate. The usual interstitial pneumonia (UIP) pattern of RA associated ILD (RA-ILD) shows some similarities to idiopathic pulmonary fibrosis, suggesting that antifibrotic therapies may have potential positive affects. In this review, we discuss the effectiveness of antifibrotic therapy for RA-ILD.

The COVID-19 pandemic has occupied the world agenda since December 2019. With no effective treatment yet, vaccination seems to be the most effective method of prevention. Recently developed vaccines have been approved for emergency use only and are currently applied to large populations. Considering both the underlying pathogenic mechanisms of autoimmune/autoinflammatory rheumatological diseases (AIIRDs) and the immunosuppressive drugs used in treatment, vaccination for COVID-19 deserves special attention in such patients. In this article, we aimed to give simple messages to the clinicians for COVID-19 vaccination in patients with AIIRDs based upon the current evidence regarding the use of other vaccines in this patient group. For this purpose, we conducted a "Pubmed search" using the following keywords: Influenza, Hepatitis B, Pneumococcal, and Shingles vaccines and the frequently used conventional and biologic disease-modifying antirheumatic drugs (DMARDs). Likewise, an additional search was performed for the COVID-19 immunization in patients with AIIRDs and considering such drugs. In summary, patients with AIIRDs should also be vaccinated against COVID-19, preferably when disease activity is under control and when there is no concurrent infection. Low-degree immunosuppression does not appear to decrease antibody responses to vaccines. Ideally, vaccinations should be done before the initiation of any biological DMARDs. Patients receiving rituximab should be vaccinated at least 4 weeks before or 6 months after treatment. Since tofacitinib may also reduce antibody responses, especially in combination with methotrexate, it may be appropriate to discontinue this drug before vaccination and to restart after 14 days of immunization. Key points ⢠COVID-19 vaccinations should preferably be made during remission in patients with autoimmune/autoinflammatory rheumatological diseases. ⢠Low-degree immunosuppression may not interfere with antibody response to vaccines. ⢠Ideally, vaccinations should be made before the initiation of any biological DMARDs. ⢠Timing of vaccination is especially important in the case of rituximab.
