Prevalence of Findings in Routine Abdominal Ultrasound in Patients with Systemic Autoimmune Rheumatic Diseases and Their Impact on Therapeutic Decision Making

Patients with systemic autoimmune rheumatic diseases (SARD) often receive abdominal ultrasound examinations to screen for organ involvement; yet, the spectrum of findings and their clinical relevance are poorly understood. We conducted a retrospective chart review of inpatients from a rheumatological referral centre with an abdominal ultrasound between 1 January2006 and 31 December 2015, examining 1092 SARD patients with a total of 1695 inpatient stays. The mean age was 55.1 years (range: 17–90 years, SD: 15.8), and the mean disease duration was 6.4 years (range: 0.0–52.8 years, SD: 9.1). A total of 87.5% of the patients were female. The most frequent ultrasound findings were hepatic steatosis (in 26.8% of all patients), splenomegaly (15.2% of all patients), pancreatic lipomatosis (14.3% of all patients) and aortic sclerosis (13.9% of all patients). Based on glucocorticoid and disease-modifying antirheumatic drug use, we identified cases where immuno-modulatory medication was escalated; there was an association between therapy escalation and the findings of hepatomegaly and pleural effusion (as tested via Fisher’s exact test). In patients with several examinations during the defined time span (n = 318), we found ultrasound findings to change, especially findings of hepatomegaly, pleural effusion and splenomegaly. When justifying decisions regarding the further treatment of a patient in the discharge letter, abdominal ultrasound results were rarely discussed. Abdominal ultrasound rarely yielded disease-specific or treatment-changing results.

Rickettsiosis with Pleural Effusion: A Systematic Review with a Focus on Rickettsiosis in Italy

Background: Motivated by a case finding of Mediterranean spotted fever (MSF) associated with atypical pneumonia and pleural effusion in which Rickettsia conorii subsp. israelensis was identified by molecular methods in the pleural fluid, we wanted to summarize the clinical presentations of rickettsiosis in Italy by systematic research and to make a systematic review of all the global cases of rickettsiosis associated with pleural effusion. Methods: For the literature search, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was followed. We chose to select only the studies published in last 25 years and confirmed both with serological and molecular assays. Results: Human cases of rickettsiosis in Italy were reported in 48 papers describing 2831 patients with very different clinical presentations; the majority was MSF accounted to R. conorii and was reported in Sicily. Pleural effusion associated with infection with microorganisms belonging to Rickettsiales was described in 487 patients. It was rarely associated with microorganisms different from O. tsutsugamushi; also rarely, cases of scrub typhus were reported outside Southeast Asia and in the largest majority, the diagnosis was achieved with serology. Conclusions: MSF, especially when caused by R. conorii subsp. israelensis, may be a severe disease. A high index of suspicion is required to promptly start life-saving therapy. Pleural effusion and interstitial pneumonia may be part of the clinical picture of severe rickettsial disease and should not lead the physician away from this diagnosis

Multidetector CT findings of primary pleural angiosarcoma : a systematic review, an additional cases report

Background To demonstrate and analyze the relatively common imaging findings in this rare primary pleural angiosarcoma (PPA). Case presentation Three cases of PPA, proven by video-assisted thoracic surgery biopsies are retrospectively reviewed. Patients were all male. Age ranges from 65 to 75 years old age (mean; 69). Major chief complaints were dyspnea and chest pain. One has a history of colon cancer, the other has a tuberculosis history and the other has no known history. Multidetector chest CT and PET CT were all done. Immunohistochemical studies were performed including CD31, CD34, or factor VIII-related antigen, vimentin, and cytokeratin. We also review the literatures on recently published PPA. All masses were from 1 to 10 cm. All three patients had multiple pleural based masses, which were ovoid in shape with relatively sharp margin in unilateral hemithorax. Multiple small circumscribed pleural masses are limited in the pleural space in two patients, whereas two, huge lobulated masses about up to 10 cm were present with pleural and extrapleural involvement in one patient. In two patients with pleural mass only, multiple pleural masses were only seen in parietal pleura in one patient and were in both visceral and parietal pleura in one patient. Pleural effusion were found in one side in one patient and in both sides in one patient. One angiosarcoma was arised from chronic tuberculotic pleurisy sequelae. All pleural masses are heterogenous with irregular internal low densities in all patients. Hematogenous metastases were found in liver, vertebra, rib in one patient, and were in lungs with mediastinal lymph node metastases in the other patient. Three patients survived for longer than 3months after diagnosis, but continued to deteriorate rapidly. Two patients underwent chemotherapy after surgical excision, and the other one with multiple metastases treated chemotherapy after CT-guided biopsy, but eventually all died. As a result of comparative analysis of a total of 13 patients’ images including 10 cases previously published, there was pleural effusion in all except 2 cases. Conclusions PPA were all necrotic without any vascularized enhancing nature, and manifested as unilateral circumscribed or localized pleural-based masses.

Total Protein–Chloride Ratio in Pleural Fluid Independently Predicts Overall Survival in Malignant Pleural Effusion at the First Diagnosis

ObjectivePre-treatment biomarkers to estimate overall survival (OS) for malignant pleural effusion (MPE) are unidentified, especially those in pleural fluid. We evaluated the relationship between OS and total protein–chloride ratio in malignant pleural effusion (PE TPClR).Materials and MethodsA retrospective study was undertaken to identify patients from 2006 to 2018 who had pathologically or cytologically confirmed MPE and received no tumor-targeted therapy. We recorded the pre-treatment clinicopathologic characteristics and follow-up status. OS was estimated by the Kaplan–Meier method, and the association between variables and OS was evaluated by Cox proportional hazards models.ResultsWe screened 214 patients who met the eligibility criteria. The optimal cutoff value for the PE TPClR was set at 0.53. The univariate analysis showed that there was a significant correlation between PE TPClR and OS (P < 0.001). The multivariate analysis between OS and the variables selected from the univariate analysis showed that the levels of neutrophil, alkaline phosphatase, neuron-specific enolase, platelets, albumin in peripheral blood, and white blood cells in pleural effusion were also independent predictors of OS.ConclusionIn patients with MPE, pre-treatment PE TPClR independently predicts OS. Although further research is necessary to generalize our results, this information will help clinicians and patients to determine the most appropriate treatment for MPE patients.
