Frequency of anti-heart autoantibodies in HIV positive and negative patients by immunofluorescence
| Cardiac specific (%) | Cardiac cross reactive (%) | |
|---|---|---|
| All HIV+ve (n = 74) | 11 (15)1-150 | 0 |
| HIV+ve normal heart (n = 37) | 4 (11) | 0 |
| HIV+ve HMD (n = 28) | 6 (21)1-150 | 0 |
| HIV+ve RVD (n = 9) | 1 (11) | 0 |
| HIV−ve IDUs (n = 14) | 0 | 2 (14) |
| HIV−ve NBDs (n = 200) | 7 (3.5) | 11 (5.5) |
↵1-150 p < 0.001 v NBD by χ2; no other significant difference between groups by χ2.
HMD, heart muscle disease; IDUs, injection drug users; NBDs, normal blood donors; RVD, isolated right ventricular dilatation; +ve, positive; −ve, negative.
