not-yet-known not-yet-known not-yet-known unknown 1 Methods Blood investigations revealed a white blood cell (WBC) count of 7,090 cells/µL (normal: 3,000-11,000 cells/µL) with neutrophil predominance at 83% (normal: 40-75%), followed by lower lymphocytes 12% (normal: 20-45%). Other differential counts were within normal limits. Hemoglobin was measured at 9.6 g/dL (normal: 11-16 g/dL), and platelet count was 152,000 cells/µL (normal: 150,000-450,000 cells/µL). Red blood cell count (RBC) was slightly low at 3.34 million/µL, and the packed cell volume (PCV) was 28.4% (normal: 36-46%). Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW) were all within normal ranges. Inflammatory markers showed a C-reactive protein (CRP) level of 103 mg/L [Less than 0.3 mg/dL is normal) and procalcitonin at 10 ng/mL (less than 0.1 ng/mL is normal), indicating a significant inflammatory response. Based on the history, examination and blood parameters, inflammatory complication of septic abortion was made and to further narrow down, additional investigations was suggested. Blood cultures were positive for methicillin-resistant Staphylococcus aureus (MRSA), while urine cultures were sterile. An iron profile revealed low serum iron levels at 11.1 µg/dL, elevated total iron-binding capacity (TIBC) at 431 µg/dL, iron saturation of 2.6%, and ferritin levels of 259.86 ng/mL, suggesting anemia of chronic disease. Liver function tests (LFTs) and renal function tests (RFTs) were within normal limits, although serum potassium was slightly reduced at 3.4 mmol/L (normal: 3.5-5.0 mmol/L). Ultrasound of Abdomen and Pelvis and Electrocardiography was normal. Echocardiography was performed, revealing vegetation on the tricuspid valve leaflet, with moderate tricuspid regurgitation (TR) and spontaneous echo contrast in the right atrium. Tricuspid annular plane systolic excursion (TAPSE) was measured and was 1.9 cm, indicating preserved systolic function with maximum length of the vegetation was measured at 2.5 cm.
