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.

Coexistence of Systemic Lupus Erythematosus and Syringomyelia: A Case From a Rural Center in Nigeria.

Systemic lupus erythematosus and syringomyelia are two distinct conditions with different pathogenetic pathways as well as diverse genetic and clinical characteristics. The coexistence of these two conditions has not been previously documented in the literature. We describe a 38-year-old male who presented with progressive bilateral weakness and pain in the lower limbs and loss of sphincteric functions three years following a diagnosis of lupus nephritis. Relevant autoantibody testing, hypocomplementemia, and biopsy-proven membranous lupus nephritis confirmed the diagnosis of systemic lupus erythematosus and magnetic resonance imaging of the spine confirmed the presence of syringomyelia. Therapy for lupus nephritis was instituted accordingly, while the patient was referred for neurosurgical intervention. The mechanism underlying syrinx formation in this patient is uncertain and, thus, further research is critical in this area.

Relationship Between Disease Severity and Resting Electrocardiograms of Adults With Sickle Cell Anemia in a Tertiary Institution in Southern Nigeria.

Introduction Sickle cell anemia (SCA) in adults has many clinical manifestations. These manifestations are due to effects of recurrent hemolysis, anemia, and ischemia-reperfusion injury on various organs, including the heart. These factors determine the severity of the disease. Objectives The aim of the study was to assess the severity of SCA using a scoring system consisting of clinical and laboratory parameters. In addition, the study aimed to determine the electrocardiographic abnormalities in the adult SCA population. Study design This was a cross-sectional, observational study conducted in the medical outpatient clinic of Irrua Specialist Teaching Hospital, Irrua, Nigeria. Methodology Sixty SCA patients who were older than 18 years old were recruited for this study between February 2017 and January 2018. Sixty healthy individuals matched for age and sex were recruited to serve as controls. Patients who were pregnant or having an acute crises were excluded from the study. Each participant had an electrocardiogram and a SCA severity score was calculated using their clinical history and complete blood count. Data analysis was carried out using the IBM Statistical Package for Social Sciences Statistics® software, version 21 (IBM SPSS Statistics for Windows, Armonk, NY) and statistical significance assigned to p-values less than 0.05. Results Severity scores for SCA ranged between 7 and 24, with a mean score of 14.5 ± 4.04. Out of the 60 patients, 14 (23.3%), 39 (65%), and seven (11.7%) participants met criteria for mild, moderate, and severe disease, respectively. Tachycardia, prolonged QTc, and the presence of ST-segment and T-wave abnormalities were significantly associated with severe SCA (p = 0.024, p = 0.027, and p = 0.018, respectively). There was positive correlation between SCA severity scores and P-wave duration (r = 0.327, p = 0.011), QRS dispersion (r = 0.298, p = 0.021), QTc interval (r = 0.332, p = 0.010), and QTc dispersion (r = 0.320, p = 0.013). Conclusion This study demonstrated that moderate and severe forms of SCA are common in our region. Tachycardia, left atrial abnormality, prolonged corrected QT interval, and the presence of ST-segment and T-wave changes are electrocardiographic findings associated with more severe forms of the disease. These abnormalities are significant etiologies of cardiac morbidity and mortality in SCA.
