Infliximab Induced Cardiac Tamponade

Aim To report the first case of cardiac tamponade related to Infliximab induction therapy in an Ulcerative Colitis patient. Methods Review of published case reports. Results This complication was likely due to a type 3 hypersensitivity immune-complex reaction resulting in a reactive pericardial effusion Discussion Though rare, this case demonstrates how autoimmune reaction to anti-TNF𝛼 therapy can initially mimic infection, as our patient presented with tachycardia, hypotension, raised inflammatory and infective markers and fever.

Cardiac tamponade as an initial presentation for systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease which follows a relapsing and remitting course that can manifest in any organ system. While classic manifestations consist of arthralgia, myalgia, frank arthritis, a malar rash and renal failure to name a few, cardiac tamponade, however, is a far less common and far more dangerous presentation. We highlight the case of a 61year-old male with complaints of acute onset shortness of breath and generalized body aches associated with a fever and chills in the ER. A bedside echocardiogram revealed a significant pericardial effusion concerning for pericardial tamponade. An emergent pericardiocentesis performed drained 800mL of serosanguinous fluid. While denying a history of any rash, photosensitivity, oral ulcers, or seizures, his physical examination did reveal metacarpal phalangeal joint swelling along with noted pulsus paradoxus of 15-200mmHg. Subsequent lab work revealed ANA titer of 1:630 and anti-DS DNA antibody level of 256IU/mL consistent with SLE. This case highlights cardiac tamponade as a rare but life-threatening presentation for SLE and raises the need to keep it in the differential when assessing patients presenting with pertinent exam findings.

Nontyphoidal cardiac salmonellosis: two case reports and a review of the literature.

Nontyphoidal Salmonella, especially Salmonella enterica, is a rare cause of endocarditis and pericarditis that carries a high mortality rate. Proposed predisposing conditions include immunodeficiency states, congenital heart defects, and cardiac valve diseases. We present 2 cases of cardiovascular salmonellosis. The first case is that of a 73-year-old woman with mechanical mitral and bioprosthetic aortic valves who died from sequelae of nontyphoidal Salmonella mitral valve vegetation, aortic valve abscess, and sepsis. The second case is that of a 62-year-old man with a recent systemic lupus erythematosus exacerbation treated with oral steroids, who presented with obstructive features of tamponade and sepsis secondary to a large S. enteritidis purulent pericardial cyst. He recovered after emergent pericardial drainage and antibiotic therapy. Identifying patients at risk of cardiovascular salmonellosis is important for early diagnosis and treatment to minimize sequelae and death. We reviewed the literature to identify the predisposing risk factors of nontyphoidal Salmonella cardiac infection.

Inflammatory activation after experimental cardiac tamponade.

BACKGROUND/PURPOSE: Cardiac tamponade is a medical emergency situation associated with a high rate of life-threatening complications, even after immediate interventions. Our aim was to characterize the acute inflammatory consequences of this event in a clinically relevant large animal model. METHODS: Cardiac tamponade was induced for 60 min in anesthetized, ventilated and thoracotomized minipigs by intrapericardial fluid administration, the mean arterial pressure (MAP) being maintained in the interval of 40-45 mm Hg (n = 8). A further group (n = 7) served as sham-operated control. The global macrohemodynamics, including the right- and left-heart end-diastolic volumes (RHEDV and LHEDV), the pulmonary vascular resistance index (PVRI) and the superior mesenteric artery (SMA) flow, were monitored for 240 min, and the intestinal microcirculatory changes (pCO2 gap) were evaluated by indirect tonometry. Blood samples were taken for the determination of cardiac troponin T and vasoactive inflammatory mediators, including histamine, nitrite/nitrate, big-endothelin, superoxide and high-mobility group box protein-1 levels in association with intestinal leukocyte and complement activation. RESULTS: The cardiac tamponade induced significant decreases in MAP, cardiac output, LHEDV and SMA flow, while the PVRI and the pCO2 gap increased significantly. After the removal of fluid from the pericardial sac, the MAP and the LHEDV were decreased, while the PVRI and the pCO2 gap remained elevated when compared with those in the sham-operated group. In the posttamponade period, the abrupt release of inflammatory mediators was accompanied by a significant splanchnic leukocyte accumulation and complement activation. CONCLUSIONS: The macrocirculatory and splanchnic microcirculatory disturbances were accompanied by a significant proinflammatory reaction; endothelin and the complement system may be significant components of the inflammatory cascade that is activated in this porcine model of pericardial tamponade.

A case of rheumatoid pericarditis associated with a high IL-6 titer in the pericardial fluid and tocilizumab treatment.

We report a 60-year-old woman with rheumatoid arthritis complicated by pericarditis. Treatment with tocilizumab improved her polyarthritis, but the pericardial effusion increased so rapidly as to cause cardiac tamponade before the treatment could prove its efficacy. Pericardial effusion disappeared after pericardiocentesis. The pericardial fluid contained a remarkably high concentration of interleukin-6 (IL-6; 351,000 pg/mL), which tocilizumab appeared to have made yet higher compared to the reported IL-6 levels in rheumatoid pericarditis. No further exacerbation of pericarditis was observed after retreatment with tocilizumab. This case has important implications in that it suggests that the prominently elevated IL-6 level in pericardial fluid during tocilizumab treatment may be an indicator of its efficacy for pericarditis.

Surgical treatment of a primary cardiac lymphoma presenting with tamponade physiology.

Primary cardiac lymphomas (PCL) are rare cardiac neoplasms that carry an ominous prognosis. They occur more frequently in immunocompromised patients. We report on an immunocompetent 67-year-old who presented with dyspnea and dysphagia. Echocardiographic evidence of impending cardiac tamponade and obstruction of the inferior vena cava (IVC) with the tumor was seen. The deteriorating hemodynamics of our patient prompted an urgent surgical intervention. Pathohistological diagnosis showed diffuse large B-cell lymphoma of centroblastic subtype. Chemotherapy remains the standard treatment of PCL, with surgery reserved for relieving life-threatening complications of the neoplasm.

Cardiac tamponade as the first manifestation of systemic lupus erythematosus in the elderly.

Although pericardial involvement is very frequent in systemic lupus erythematosus, cardiac tamponade is extremely rare as the first manifestation of the disease. On the other hand, systemic lupus erythematosus is a disease that predominantly affects young women, and it is a very uncommon condition in the elderly. We report a 91-year-old woman diagnosed with cardiac tamponade, which was the presenting clinical feature of a previously undiagnosed case of systemic lupus erythematosus.

A case of anti-Jo1 myositis with pleural effusions and pericardial tamponade developing after exposure to a fermented Kombucha beverage.

The pathogenesis of the idiopathic inflammatory myopathies has been postulated to be an environmental trigger causing the expression of the disease in a genetically predisposed patient. We report a case of anti-Jo1 antibody-positive myositis which was associated with pleural effusions, pericardial effusion with tamponade, and 'mechanic's hands', probably related to the consumption of a fermented Kombucha beverage. Kombucha 'mushroom', a symbiosis of yeast and bacteria, is postulated to be the trigger for our patient's disease owing to the proximity of his symptoms to the consumption of the Kombucha beverage.

A case of rheumatoid pericarditis with high concentrations of interleukin-6 in pericardial fluid.

A case of rheumatoid pericarditis that developed into cardiac tamponade without deterioration of rheumatoid arthritis is described. The concentration of interleukin-6 (IL-6) in pericardial fluid was notably increased compared with serum. IL-6 may be associated with progression or maintenance of rheumatoid pericarditis.

Cardiac tamponade preceding adrenal insufficiency--an unusual presentation of Addison's disease: a report of two cases.

Two cases of young healthy males presenting with cardiac tamponade and developing clinical adrenal insufficiency within a few weeks are described. On presentation they had a brisk inflammatory response with complement activation. Both had signs of subclinical hepatitis, and both have later shown evidence of thyroid involvement. The possibility of a connection between pericarditis and adrenal insufficiency is discussed.
