Infective endocarditis frequently causes rheumatic symptoms, with 25% of patients experiencing disabling musculoskeletal issues. Streptococcus bovis endocarditis specifically shows a strong association with low back pain.

Area of Science:

  • Infectious Diseases
  • Rheumatology
  • Cardiology

Background:

  • Infective endocarditis (IE) is a serious infection affecting heart valves.
  • Rheumatic manifestations are frequently observed in patients with IE, but their spectrum and specific associations require further elucidation.

Purpose of the Study:

  • To analyze the prevalence and characteristics of rheumatic manifestations in patients with infective endocarditis.
  • To investigate potential associations between specific microorganisms and particular musculoskeletal symptoms.

Main Methods:

  • Retrospective case analysis of 87 patients with 93 episodes of infective endocarditis over an 11-year period (1980-1990).
  • Documentation and categorization of musculoskeletal symptoms and signs, including low back pain, arthralgia, arthritis, and other localized pains.

Main Results:

  • Twenty-two percent (25%) of patients experienced disabling musculoskeletal symptoms.
  • Low back pain was common (13 patients), with two cases showing septic discitis or vertebral osteomyelitis.
  • Streptococcus bovis endocarditis was associated with prominent low back pain in four out of seven patients.

Conclusions:

  • Rheumatic manifestations are a significant clinical feature of infective endocarditis.
  • Specific bacterial species, such as Streptococcus bovis, may have a predilection for causing particular musculoskeletal symptoms, notably low back pain.
