Production of frothy, dark urine should raise suspicion for glomerular disease. One common cause of postinfectious glomerulonephritis is infection with β-hemolytic streptococci, such as Streptococcus pyogenes. In addition to causing nephritic syndrome, S. pyogenes can also cause acute rheumatic fever if left untreated. Although rheumatic fever is a well-known cause of pancarditis, it can also induce Sydenham chorea, a restless, uncontrollable movement of the extremities.
