Table 1.
Distribution of patients with acute and chronic Q fever that showed specific autoantibodies (IgG isotype) by indirect immunofluorescence.
| Specific autoantibodies | Acute Q fever (n = 24)(%) | Chronic Q fever (n = 34)(%) |
| ANA | 3(12.5) | 5(14.7) |
| dsDNA | 1(4.1) | 3(8.8) |
| ANCA | 3(12.5) | 4(11.8) |
| ASMA | 7(29.2)* | 9(26.5)* |
| PCA | 0 | 3(8.8) |
| CMA | 3(12.1)* | 13(38.3)# |
| Total positive patients | 13(54.2) | 23(67.6) |
ANA: Anti-nuclear antibodies;
dsDNA: Anti-double strand DNA antibodies;
ANCA: Anti-neutrophil antibodies;
ASMA: Anti-smooth muscle antibodies;
PCA: Anti-parietal cells antibodies;
CMA: Anti-cardiac muscle antibodies.
*: p < 0.05 as compared with healthy controls
