Explanation

Group A Streptococcus pyogenes is a bacitracin sensitive beta-hemolytic gram-positive bacterium which can cause pyogenic, toxigenic and immunologic illnesses. This patient most likely has scarlet fever which presents with streptococcal pharyngitis, circumoral pallor and a sandpaper-like body rash. Streptococcal infections can be complicated with rheumatic fever or post streptococcal glomerulonephritis. Laboratory findings include the presence of anti-DNase B antibodies and elevated anti-streptolysin (ASO) titers. Antibodies to the M protein enhance host defenses but can also cause rheumatic fever due to molecular mimicry. Prophylaxis with penicillin is indicated to prevent rheumatic fever. Rheumatic fever is characterized by myocarditis, migratory polyarthritis, erythema marginatum, Sydenham chorea and subcutaneous nodules. Acute post streptococcal glomerulonephritis presents with hematuria, periorbital edema and hypertension. Muscular spasms are not features of rheumatic fever or post streptococcal glomerulonephritis.
