A 61-year-old man was admitted to the hospital with an atypical pain lumbar with oligoanuria. Other comorbidities were: arterial hypertension, diabetes mellitus and smoking .On examination the patient was comfortable at rest, with a heart rate of 89 b.p.m. and a blood pressure of 147/2 mmHg. Normal S1 and S2 heart sounds were present. There were no signs of heart failure present. Patients complained of pain in hypogastrium on palpation. Creatinine 2.33 mg / dL. PCR 72. The immunological studies were normal (including IgG and IgA serological levels, antinuclear antibodies, extractable nuclear antigens, anti-neutrophil cytoplasmic antibodies. An Body CT was performed, it shows mass that includes the ureters as well as the iliac arteries and parietal thickening in aorta wall. The positron emission tomography–computed tomography (PET CT) scans was performed that evidences pathological hypermetabolism that surrounds both primitive iliac arteries with maximum SUV 12 g / ml. Pathological hypermetabolism in ascending aorta until reaching arch with maximum SUV of 9.1 mg / ml compatible with periaortitis in the ascending aorta. A study was completed with retroperitoneal mass biopsy that showed areas of retroperitoneal fibrosis with predominantly lymphoplasmacytic areas. IgG4 / IgG> 40% , Obliterative involvement of small venules suggestive of IgG4 disease. A transthoracic echocardiogram was performed which showed normal biventricular function, absence of significant valvular disease and thickening of the aortic wall compatible with periaortitis. The patient started glucocorticoid therapy with favorable response. A PET CT control was performed that showed disappearing retroperitoneal masses around iliac vessels and disappearance of activity in lateral wall of aorta and decrease activity about ascendent aorta. DIAGNOSIS : IgG4 -related aortitis Abstract P273 Figure.

Background The Combination Antibiotic therapy for MEthicillin Resistant Staphylococcus Aureus (CAMERA2) trial ceased recruitment in July 2018, noting a higher proportion of patients in the intervention arm (combination therapy) developed acute kidney injury (AKI) compared to the standard therapy (monotherapy) arm. We analysed the long-term outcomes of participants in CAMERA2 to understand the impact of combination antibiotic therapy and AKI. Methods Trial sites obtained additional follow-up data. The primary outcome was all-cause mortality, censored at death or the date of last known follow up. Secondary outcomes included renal failure or a reduction in kidney function (a 40% reduction in eGFR to less than 60 mL/min/1.73m2). To determine independent predictors of mortality in this cohort, adjusted hazard ratios were calculated using a Cox proportional hazards regression model. Results This post-hoc analysis included extended follow-up data for 260 patients. Overall, 123 of 260 (47%) of participants died with a median population survival estimate of 3.4 years (235 deaths per 1000 person years). Fifty-five patients died within 90 days after CAMERA2 trial randomisation; another 68 deaths occurred after day 90. Using univariable Cox proportional hazards regression, mortality was not associated with either the assigned treatment arm in CAMERA2 (hazard ratio 0.83 [95% CI 0.59–1.19], p = 0.33) or experiencing an AKI (hazard ratio at one year 1.04 [95% CI 0.64–1.68], p = 0.88). Conclusion In this cohort of patients hospitalised with MRSA bacteraemia, we found no association between either treatment arm of the CAMERA2 trial or AKI (using CAMERA2 trial definition) and longer-term mortality.

The conglomerate of microorganisms, inflammatory cells, fibrin and platelets that constitutes the characteristic lesion of infectious endocarditis, that is, vegetation, was considered as a major criterion of infectious endocarditis in the 90s thanks to the development of ultrasound. Ecocardiography allows the diagnosis of complications derived from the infection, such as valvular perforation, prosthetic dehiscence, fistula or abscesses. One of the most infrequent complications is the mitral pseudoaneurysm. It has its origin in the impact of a jet of aortic regurgitation on the anterior leaflet of the mitral valve, which is why we have called it mitral fracking. A 60-year-old man who had a recent history of pneumonia and for whom he was still receiving antibiotic treatment, debuted suddenly with dyspnea of minimal effort. He went to a cardiology clinic where he was found to have severe mitral regurgitation. He was directly derived to cardiac surgery of our hospital. Prior to the intervention, a transesophageal ultrasound study was performed in our department, which showed the following findings: a bicuspid aortic valve with a small vegetation on its aortic surface (Figure A, surgical piece), a protuberance on the anterior mitral leaflet (Figure B) with internal flow that caused systolic expansion towards the atrium (Figure C) and diastolic collapse towards the ventricle (figure D): the mitral pseudoaneurysm. The therapeutic action was based on the replacement of both valves with mechanical prostheses. The blood cultures were negative, but the surgical piece revealed unequivocal histological findings of infectious endocarditis. Currently, the patient is stable and the valves are normofunctional in the regular follow-up controls. Abstract 91 Figure.
