Clinical Information

Endocarditis - Inflammation of the inner lining of the heart (ENDOCARDIUM), the continuous membrane lining the four chambers and HEART VALVES. It is often caused by microorganisms including bacteria, viruses, fungi, and rickettsiae. Left untreated, endocarditis can damage heart valves and become life-threatening.

Endocarditis, Bacterial - Inflammation of the ENDOCARDIUM caused by BACTERIA that entered the bloodstream. The strains of bacteria vary with predisposing factors, such as CONGENITAL HEART DEFECTS; HEART VALVE DISEASES; HEART VALVE PROSTHESIS IMPLANTATION; or intravenous drug use.

Endocarditis, Non-Infective - Formation of a non-infectious THROMBUS, referred to as vegetation, on previously undamaged ENDOCARDIUM. It usually occurs as a complication of connective-tissue diseases and cancers because of the associated hypercoagulable state (see THROMBOPHILIA).

Endocarditis, Subacute Bacterial - ENDOCARDIUM infection that is usually caused by STREPTOCOCCUS. Subacute infective endocarditis evolves over weeks and months with modest toxicity and rare metastatic infection.

Eosinophils - Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.

Hypereosinophilic Syndrome - A heterogeneous group of disorders with the common feature of prolonged eosinophilia of unknown cause and associated organ system dysfunction, including the heart, central nervous system, kidneys, lungs, gastrointestinal tract, and skin. There is a massive increase in the number of EOSINOPHILS in the blood, mimicking leukemia, and extensive eosinophilic infiltration of the various organs.

Rat-Bite Fever - A syndrome characterized by recurring fever, rash, and arthralgias occurring days to weeks after a rat bite. The causative agents are either Streptobacillus moniliformis or Spirillum minus.
