Table 1.

Prevalence of non-organ specific autoantibodies in anti-HCV positive patients (n = 78).

Autoantibody (Titer ≥ 1:40 by IFL)	n (%)
ANA	15 (19.2)
SMA	25 (32.0)
AMA	2 (2.6)
ANCA	4 (5.2)
LKM	0 (0)
Any autoantibody	36 (46.2)
ANA and/or SMA	33 (42.3)

All serum autoantibodies were determined by indirect immunofluorescence (IFL). A serum dilution of at least 1:40 was considered as a positive result. ANA, anti-nuclear antibodies; SMA, anti-smooth muscle anibodies; AMA, anti-mitochondrial antibodies, ANCA, anti-neutophil-cytoplasmatic antibodies; LKM, anti liver/kidney microsomal antibodies
