The prevalence of non-vascular pulmonary manifestations in Takayasu's Arteritis patients: A Retrospective multi-centred Turkish cohort study.

OBJECTIVES: Takayasu's arteritis (TAK) is a rare vasculitis characterized by inflammation of intermediate- to large-size arteries. Although pulmonary artery involvement (PAI) is an expected finding in some TAK patients, data on non-vascular pulmonary involvement (NVPI) are limited. We aimed to investigate the frequency of NVPI, including parenchymal infiltration, nodules/cavities, pleural effusion, and haemorrhage, in TAK. METHOD: We assembled a retrospective cohort of TAK patients from nine tertiary centres in Turkey. The demographics and clinical characteristics of patients were extracted from medical records and the imaging findings were evaluated for pulmonary manifestations. RESULTS: As of January 2021, 319 TAK patients (female/male 276/43; mean age 42.4 ± 13.5 years) were recruited. Eighty-two patients had cough and/or dyspnoea and four had haemoptysis as pulmonary symptoms. On computed tomography assessment, the overall frequency of NVPI was 7.2%; parenchymal infiltrations were present in 10 (3.1%), pleural effusion in eight (2.5%), nodules/cavities in six (1.9%), and pulmonary haemorrhage in four patients (1.3%). In the whole cohort, 10.3% of patients had pulmonary artery hypertension (PAH) and 5.6% had PAI. Among patients with PAH or PAI, the overall frequency of NVPI was significantly higher than in the rest of the group. CONCLUSIONS: In this TAK cohort from Turkey, we observed NVPI in 7.2% of patients, with parenchymal infiltrations being the most common, followed by pleural effusion. Notably, NVPI was more frequent in patients with PAH or PAI. Although not as common as PAI, NVPI should be kept in mind, especially in TAK patients with PAH or PAI.

Risk factors for malignancy in systemic sclerosis patients.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.

Rheumatoid pleural effusion with nodular pleuritis. A rare presentation of rheumatoid arthritis.

Rheumatoid pleural effusion and lung nodules are unusual complications of rheumatoid disease that typically present subsequently to other more common manifestations of rheumatoid illness. However, these complications may occasionally occur before or concurrently with the development of joint manifestations of disease. We report the case of a 41-year-old female patient with rheumatoid pleural effusion and lung nodule arising simultaneously with the onset of joint symptoms. The patient underwent thoracentesis followed by video-assisted thoracoscopic biopsy to result in a diagnosis of rheumatoid pleuritis and nodular disease. A high index of suspicion and coexistence of the cytologic and histopathologic effusion picture characteristic of rheumatoid pleuritis are of clinical importance in making a diagnosis.
