The following are the most important diseases or complications that may be contributed to by vasculitides:
Consequential diseases in general
- Vasculitis can lead to stenosis (narrowing) and obliteration (occlusion) of a vessel, as well as to aneurysm (bulging of a vessel)
Eosinophilic granulomatosis with polyangiitis (EGPA), formerly Churg-Strauss syndrome (CSS)
Diseases
Respiratory System (J00-J99)
- Pulmonary syndrome – combination of renal and pulmonary vasculitis (inflammation of the (mostly) arterial blood vessels in the kidneys and lungs) including necrotizing extracapillary proliferative glomerulonephritis (inflammation of the glomeruli (renal corpuscles) of the kidneys)
Cardiovascular system (I00-I99).
- Cardiac arrhythmias (arrhythmias), unspecified.
- Myocardial infarction (heart attack)
- Thromboembolism (occlusion of a pulmonary artery by a blood clot).
Psyche – nervous system (F00-F99; G00-G99)
- Paralysis, unspecified
Granulomatosis with polyangiitis (GPA), formerly Wegener’s granulomatosis
Diseases
Respiratory System (J00-J99)
- Pulmonary syndrome – combination of renal and pulmonary vasculitis (inflammation of the (mostly) arterial blood vessels in the kidneys and lungs) including necrotizing extracapillary proliferative glomerulonephritis (inflammation of the glomeruli (renal corpuscles) of the kidneys)
Eyes and eye appendages (H00-H59).
- Episcleritis – inflammation of connective tissue layers on the sclera (3.5%).
- Keratoconjunctivitis sicca (KCS) – inflammation of the conjunctiva associated with decreased tear secretion and keratitis (4-15%).
- Pseudotumor orbitae – nonspecific inflammatory infiltration of the orbit (bony orbit), which usually occurs unilaterally.
- Scleritis – inflammation of the sclera (16-38%).
Cardiovascular system (I00-I99)
- Ischemias, especially in the heart, CNS (central nervous system), kidney, liver, gastrointestinal tract (gastrointestinal tract).
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).
- Pulmonary hemorrhage
Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99)
- Acute renal failure (ANV)
Further
- Acute organ failure, unspecified
Kawasaki syndrome (MCLS)
Diseases
Cardiovascular system (I00-I99)
- Myocardial infarction (heart attack)-likely based on aneurysms of the coronaries (vascular outpouchings of the coronary arteries) as a late consequence of the disease
Microscopic polyangiitis (MPA)
Respiratory System (J00-J99)
- Pulmonary syndrome – combination of renal and pulmonary vasculitis (inflammation of the (mostly) arterial blood vessels in the kidneys and lungs) including necrotizing extracapillary proliferative glomerulonephritis (inflammation of the glomeruli (renal corpuscles) of the kidneys)
Musculoskeletal system and connective tissue (M00-M99).
- Capillaritis of the lung with alveolar hemorrhage syndrome (hemorrhage).
Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99).
Polyarteritis nodosa (PAN; panarteritis nodosa)
Diseases
Cardiovascular System (I00-I99).
Schönlein-Henoch purpura
Diseases
-
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Ileus (intestinal obstruction)
- Ischemia (reduced blood flow) in a section of the intestine.
- Perforation (rupture) of the intestine
- Ulcus ventriculi (stomach ulcer)
Genitourinary system (kidneys, urinary tract – reproductive organs) (N00-N99)
- Acute renal failure
- Chronic renal insufficiency (kidney weakness)
- Mesangioproliferative glomerulonephritis (inflammation of the glomeruli/renal corpuscles) with mesangial IgA deposits.
