Predominant Involvement of the Aortic Root in a Patient with Anti-neutrophil Cytoplasmic Antibody-associated Vasculitis: Congestive Heart Failure due to Subacute Severe Aortic Regurgitation and Reversible Conduction Disturbance.

Predominant Involvement of the Aortic Root in a Patient with Anti-neutrophil Cytoplasmic Antibody-associated Vasculitis: Congestive Heart Failure due to Subacute Severe Aortic Regurgitation and Reversible Conduction Disturbance. Intern Med. 2019 Nov 08;: Authors: Yatomi A, Mori S, Kawauchi H, Shono A, Shimoyama S, Tanaka H, Okano T, Inoue T, Jimbo N, Morinobu A, Hirata KI Abstract A 72-year-old woman was referred to our institution with decompensated congestive heart failure owing to subacute severe aortic regurgitation and mitral regurgitation. Her blood sample tested positive for myeloperoxidase anti-neutrophil cytoplasmic antibody (ANCA). Cardiac computed tomography revealed abnormal thickening and shortening of the aortic valvar leaflets as well as wall thickening of the sinuses of Valsalva. Based on the diagnosis of ANCA-associated vasculitis, predominantly involving the aortic root, prednisolone administration was initiated, which failed to improve the valvar dysfunction. The patient underwent aortic root replacement and mitral annuloplasty. Histopathology confirmed severe inflammation involving both the aortic valvar sinuses and leaflets.

Authors: Guo L, Chen B, Zhang L, Deng Y, Li H, Shi QD Abstract A 49-year-old female patient developed chest tightness and shortness of breath without apparent cause and presented to a local hospital. Chest radiography indicated increased thickening of the lung texture, increased multiple patchy densities in the lower lobes of the bilateral lungs and a slightly enlarged thyroid. The patient was treated for pulmonary infection with antibiotics but the symptoms persisted. A repeated CT scan revealed ground-glass attenuation of the bilateral lungs with multiple flaky exudates and visible bronchogenic signs. The symptom...

He was evaluated at an outside hospital two months earlier, and was found to have methicillin-resistant Staphylococcus aureus bacteremia, lower extremity cellulitis, and acute decompensated congestive heart failure (CHF). He clinically improved over one week, his autoimmune workup was negative, and he was discharged. He failed to follow up with nephrology, cardiology, and dermatology, and st...

We present a case of this condition in a 65-year-old woman with a past medical history of rhinosinusitis and recent episodes of asthma, that developed palpable purpura, sensory deficiency and excruciating pain mainly in the lower limbs. A significant hypereosinophilia and elevated troponin level were found, although she had not cardiac symptomatology. Cardiovascular magnetic resonance revealed late gadolinium enhancement and a severe reduction of the left ventricular ejection fraction. Mononeuritis multiplex was documented and diagnosis was confirmed by biopsy. Complementary cardiac investigation is mandatory in any patien...

The workup included urinalysis, which showed proteinuria, and the exam was consistent with myxedema and pedal edema. He had a history of rheumatoid arthritis, leukocytoclastic vasculitis and Sjögren's syndrome, diabetes, and monoclonal gammopathy of unknown significance (MGUS).The patient also had shortness of breath for a month and pleural effusions on outpatient chest x-ray. He had taken Humira, methotrexate (MTX), and steroids, but his arthritis and Sjögren'...

Authors: Nakayama T, Murai S, Ohte N Abstract Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare type of systemic vasculitis. Cardiac involvement is the main cause of death in patients with this disease. We herein report a case of congestive heart failure in a patient with EGPA. Neither 67Ga scintigraphy nor cardiac magnetic resonance imaging detected inflammation of the myocardium; however, myocardial biopsy revealed numerous infiltrating inflammatory cells, thereby fulfilling the criteria of inflammatory dilated cardiomyopathy. We improved the LV systolic function by increasing the patient's prednisol...

We report a rare case of type I cryoglobulinemic vasculitis with cardiac involvement who developed progressive heart failure during the diagnosis. Diagnosis was made by the presence of cryoglobulins and endomyocardial biopsy. After bortezomib-containing treatments, plasma cryoglobulin turned to negative and clinical condition gradually improved. We report a rare case of a 42-year-old man with cryoglobulinemia (CG) in whom a progressive congestive heart failure developed during the diagnosis. Diagnosis was confirmed by endomyocardial biopsy. An anti-plasma cell dyscrasia treatment strategy was adopted and produced a favorab...

​BY AARON SNYDER, MDInfectious processes, such as streptococcal infections, can partially masquerade as alternative diagnosis. Streptococcal infections are a frequent source of infection treated by emergency physicians, and it is crucial that the appropriate tests, antibiotics, and hospitalization are used to recognize rash patterns and to identify causes and the differential of causation.A 60-year-old woman presented from her primary medical doctor's office with fever, fatigue, tachycardia, and facial discomfort for two days that developed into a malar rash. The patient reported one day of fever, several days of sore th...

CONCLUSION: In patients with inflammatory rheumatic diseases, the elevated cardiovascular risk should be kept in mind and preventive measures should be initiated early. This subject should be further studied in controlled trials so that the treatment options for patients with cardiac involvement can be evaluated. PMID: 28407841 [PubMed - in process]
