Multiple Systemic Infectious Disease Syndrome (MSIDS)

MSIDS is a term coined by Richard Horowitz, MD, used to describe a “symptom complex”  that can create persistent and tenacious illness. Instigated by Lyme disease and/or associated tick borne co-infections, other factors, such as parasitic or fungal infections, allergies, environmental toxicity, and compromised immune function, and many other, can create an illness that may be unique to an individual, making diagnosis and treatment a difficult and puzzle-solving process.

MSIDS Symptoms Can Include:

  • Abnormal liver functions
  • Allergies
  • Autonomic nervous system dysfunction
  • Endocrine abnormalities
  • Environmental toxicity
  • Enzyme deficiencies
  • Functional medicine abnormalities in biochemical pathways
  • Gastrointestinal abnormalities
  • Immune dysfunction
  • Inflammation
  • Mitochondrial dysfunction
  • Neuropsychological issues
  • Nutritional deficiencies
  • POTS (Postural Orthostatic Tachycardia Syndrome)
  • Pain issues
  • Physical de-conditioning
  • Sleep disorders
  • Day sweats, night sweats, chills
  • Shortness of breath with unexplained cough, possibly from babesiosis, a malaria-type parasite contracted through tick bites.
