Cardiac tamponade as the initial symptom due to systemic lupus erythematosus in a young man: A case report

Case report: Severe sinus tachycardia as a leading manifestation of systemic lupus erythematosus flare

Systemic lupus erythematosus (SLE) is known to have various cardiac manifestations, including arrhythmias and tachycardia. However, it is rare to encounter severe sinus tachycardia as a presenting feature in patients with SLE. Herein, we present a case of a 32-year-old Filipino female with a history of recurrent hospital admissions due to palpitations and uncontrolled tachycardia. Despite trying various symptomatic treatments, her symptoms remained persistent. Ultimately, the patient was diagnosed with SLE during her hospital stay. Eventually, her symptoms improved after initiating steroids. In conclusion, severe sinus tachycardia could be an unusual presentation of SLE that physicians should consider.

Cardiac Tamponade, an Unusual First Presentation of Systemic Lupus Erythematosus: A Case Report in a Rural Tertiary Hospital

Systemic lupus erythematosus (SLE) is a condition that manifests in a variety of ways. Although pericarditis and pericardial effusion are frequent cardiac manifestations of SLE, cardiac tamponade is rarely reported, especially as the initial manifestation of the disease. We describe a 38-year-old Nigerian lady who presented with three months of progressive dyspnea. She had intermittent fever, tachycardia, tachypnea, hypotension, jugular vein distension, and muffled heart sounds. Echocardiography confirmed cardiac tamponade. The ANA, anti-dsDNA, and anti-Sm antibodies were positive. She had a high ESR and low levels of blood complements. The diagnosis of SLE was established based on the 2019 EULAR/ACR classification criteria. She was treated with intravenous methylprednisolone, oral prednisolone, and hydroxychloroquine after undergoing an emergency echo-guided pericardiocentesis. She responded well to treatment, and she is currently being followed up on an outpatient basis. Clinicians should consider SLE as a differential when evaluating patients with pericardial effusion, as an accurate and timely diagnosis could be lifesaving.

Calcified constrictive pericarditis resulting in tamponade in a patient with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with multiorgan involvement, including heart. Pericarditis-the most common cardiac manifestation-occurs in up to 50% of cases, resulting in positive treatment outcomes. Rarely, it evolves to hazardous complications. A 50-year-old woman with SLE in clinical remission, receiving hydroxychloroquine 400 mg/day, presented to us with severe chest pain and low-grade fever. Physical examination revealed a friction rub and decreased breath sounds at the right lung base. Laboratory evaluation demonstrated leukopenia, thrombocytopenia, low C4 levels, and high acute phase reactants. Chest X-ray exhibited cardiomegaly, calcified pericardium, and right pleural effusion, confirmed by CT scan. PPD skin test and IGRA were both negative. Pericardial fluid, blood, and urine cultures for bacteria and fungi, as well as Gram and Ziehl-Neelsen stains were negative. Serological tests for viruses were also negative. The patient was diagnosed with calcified constrictive pericarditis (CP) due to SLE. She was treated with cyclophosphamide and methylprednisolone pulses, without improvement. Her clinical condition deteriorated, developing signs and symptoms compatible with cardiac tamponade (TMP), which was confirmed by Doppler echocardiography. The patient underwent pericardiectomy. A dramatic response was noted and she was discharged with prednisone 50 mg/day and azathioprine 100 mg/day. Thus, we review and discuss the relevant literature of SLE cases with CP or TMP. When an SLE patient presents with CP, infectious causes should be excluded first. To the best of our knowledge, this is the only case of SLE and calcified CP leading to TMP, hence physicians should be aware of this complication.

Cardiac Tamponade in an 18-year-old Male with Undiagnosed Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a multisystem, autoimmune condition of extremely variable presentation and prognosis. While pericardial effusion is a common disease sequela, subsequent tamponade is a rare, potentially fatal complication. We present the case of an 18-year-old, previously healthy male who presented to the emergency department with a chief complaint of abdominal pain and hematochezia. Workup revealed massive pericardial effusion with tamponade pathophysiology requiring emergent pericardiocentesis, with further workup confirming a diagnosis of SLE. While SLE often presents in an indolent manner, cardiac tamponade may be the initial presentation of this disease.
