General complications of angina to group A streptococcus (GAS)
Strep Throat Symptoms
usually heal spontaneously after a few days, whether viral or bacterial. In cases have now become extremely rare, tonsillitis beta hemolytic streptococcus group A (GAS), however, can lead to immunological complications (rheumatic fever, acute glomerulonephritis, Sydenham's chorea).
Rheumatic fever (RAA) is an inflammatory disease that affects the large joints and, in some cases, the heart valves.
In 60-70 years, the risk of developing rheumatic fever following an untreated angina was estimated at 3-4 cases per 1,000 patients affected *. Today, the number of new cases per year in industrialized countries is estimated at between 0.5 and 1.5 per 100,000 children aged 5 to 17 to 18 years **.
Acute glomerulonephritis (GNA)
Acute glomerulonephritis is a disorder that affects the kidneys.
This is a disease that has virtually disappeared from us. The number of admissions to a GNA has changed from 3.4 to 6 per 100,000 per year during 1968-1970 to 0.7 to 1.3 per 100,000 per year during 1983-1987. ***
Sydenham's chorea (St. Vitus's dance)
Sydenham's chorea or "St. Vitus Dance" is a central nervous system that causes involuntary movements and is accompanied by fever. This disease occurs in 10% of cases of attacks of rheumatic fever. It usually heals spontaneously within a few weeks.
