Epidemiological characteristics, etiological spectrum, and outcomes of adult patients with pericardial effusion at a Teaching Hospital in Somalia.

BACKGROUND

Pericardial effusion (PE) is an abnormal fluid volume in the pericardial space and is a common clinical entity. The incidence of PE is estimated diversely and depends on risk factors, etiologies, and geographic locations.

OBJECTIVES

This study aimed to assess the clinical characteristics, etiologic spectrum, echocardiographic features, and outcomes among patients with different types of PE.

METHOD

This retrospective observational study included 93 patients with confirmed PE. Their medical records were reviewed in the hospital information system of Mogadishu Somali Turkish Training and Research Hospital between April 2022 and September 2022. Patient demographics, clinical characteristics, chest X-rays, echocardiography, laboratory findings, management approaches, and outcome reports were reviewed and recorded.

RESULTS

Out of the 3000 participants, 3.1% ( = 93/3000) met the definition of definitive PE. In this study, we included 51 females and 42 males. Among the patients, 86% ( = 80) had at least one comorbidity, with diabetes (38.7%) and hypertension (37.6%) being the most common. The most frequently reported clinical presentation findings were shortness of breath (67.7%), chest pain (49.4%), cough (47.3%), and palpitations (47.3%). Cardiac tamponade developed in 9.7% ( = 9) of the patients. Pericardial taps were performed in 64.5% of the cases. Our analysis showed that the most common cause of PE was cardiac disease ( = 33, 35.4%), followed by tuberculosis (TB) ( = 25, 26.8%), uremic pericarditis ( = 24, 25.8%), and hypothyroidism ( = 10, 10.7%). Regarding the severity of PE based on echocardiographic findings, nearly half of the patients ( = 46, 49.4%) had mild PE, whereas 26.8% ( = 25) had moderate PE, and 23.6% ( = 22) had severe PE. Two-thirds of the cases (66.6%) were managed with furosemide, 48 (51.6%) patients were treated with an anti-inflammatory, hemodialysis was performed in 24 (25.8%) patients and antituberculous medications were administered to 7 (7.5%) patients. Out of the 93 patients, 24 (25.8%) died during the hospital stay. It was determined that the mortality risk of patients with renal failure was 7.518 times higher than those without ( = 0.004), and the risk for those with TB was 5.554 times higher than those without ( = 0.011). Other variables were not influential on mortality ( > 0.050).

CONCLUSION

Our study results demonstrate the epidemiological profile of PE in Somalia. The leading causes of PE were cardiac diseases, uremic pericarditis, TB, and hypothyroidism. PE is a significant cause of morbidity and mortality in Somalia, especially in individuals with renal failure and TB infection.
