Gross haematuria was found to be associated with AKI in one study, whereas another study concluded high ASO titer
, high urine specific gravity, severe haematuria and pyuria in the early phase of illness with APSGN to be possible risk factors for an atypical presentation.
The contribution of ASO titer
to the diagnosis is only important in terms of exclusion of the disease when low levels are found.
Equally, ASO titer
reached normal values after treatment.
was raised in 65% psoriatics and 19.6% non-psoriatic controls.
When the ASO titer
does not rise, the anti-DNAase B titer usually does.
This study has proved anemia (88.89%), elevated ESR (47.2%) positive CRP (86.11%) and ASO titer
more than 400 IU/ml (69.44%) are the frequent laboratory abnormalities among the children with Acute Rheumatic fever / Rheumatic heart disease.
Our patient's neuropsychiatric symptoms have disappeared completely following the antibiotic treatment despite the persistence of high ASO titer
. ASO is an antibody response peaking in 2-4 weeks and its blood levels may remain high for about 6-8 weeks.
A probable case of GAS pneumonia required a positive throat or sputum culture for GAS or an ASO titer
of >250 Todd units in the absence of another identified etiologic agent.
There is an ongoing debate among clinicians about the real utility of ASO titer
Recommended work-up to investigate possible triggers includes a CBC with differential, sedimentation rate, CRP, ASO titers
or anti-DNase B titers, tuberculin skin test or interferon-gamma TB test, and chest x-ray.
