The following are the most important diseases or complications that may be contributed to by leptospirosis (Weil disease):
Respiratory system (J00-J99)
- ARDS (adult respiratory distress syndrome; shock lung).
Eyes and eye appendages (H00-H59).
- Chorioretinitis – inflammation of the choroid (choroid) with retinal (retina) involvement.
- Iritis (inflammation of the menstrual membrane).
- Iridocyclitis – inflammation of the iris with involvement of the ciliary body.
- Uveitis – inflammation of the middle eye skin.
Blood, blood-forming organs – immune system (D50-D90).
- Hemolysis – destruction of red blood cells.
Cardiovascular system (I00-I99)
- Heart failure (cardiac insufficiency)
- Myocarditis (inflammation of the heart muscle)
- Pericarditis (inflammation of the pericardium)
Liver, gallbladder, and bile ducts-pancreas (pancreas) (K70-K77; K80-K87).
- Liver failure
Mouth, esophagus (food pipe), stomach and intestines (K00-K67; K90-K93).
- Gastrointestinal bleeding
Musculoskeletal system and connective tissue (M00-M99).
- Rhabdomyolysis – decay of large muscle masses that may be due to severe injury.
Psyche – nervous system (F00-F99; G00-G99).
- Aseptic meningitis (meningitis).
- Cerebral hemorrhage
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).
- Cardiogenic shock – form of shock caused by weakened pumping action of the heart.
- Pulmonary hemorrhage
Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99)
- Renal insufficiency (kidney weakness) to renal failure.
Further
- Multi-organ failure (MODS, Multi organ dysfunction syndrome; MOF: Multi organ failure) – simultaneous or sequential failure or severe functional impairment of various vital organ systems of the body.
