On examination: temperature- 38,5°C, swollen knee and ankle joints, pulse- 106 bpm, rhythmic, AP- 90/60 mm Hg, heart borders without changes, sounds are weakened, soft systolic apical murmur. What indicator is connected with possible etiology of the process?

Answer options

1. Seromucoid
2. Antistreptolysine-0

Explanation

A 18 y.o. male patient complains of pain in knee and ankle joints, temperature elevation to 39,50C.He had a respiratory disease 1,5 week ago. On examination: temperature- 38, 50C, swollen knee and ankle joints, pulse- 106 bpm, rhythmic, AP- 90/60 mm Hg, heart borders without changes, sounds are weakened, soft systolic apical murmur. What indicator is connected with possible etiology of the process?The antistreptolysin O (ASO) titer test is a blood test that checks for a strep infection. The patient has respiratory disease 1.5 weeks ago. Pain in knee and ankles elevated temperature thus suspect of step infection that is associated with rheumatic fever. ASO titer test measures antibodies produced by our body in response to a toxin known as streptolysin O. Streptolysin O is a toxin produced by group A Streptococcus (GAS) bacterium.
