Alexithymia in HIV, HCV and coinfections.

Recent studies show that alexithymia, an impairment of emotional processing, plays a role in HIV and HCV infections, although little is known about about alexithymia in HIV/HCV coinfection. This study aimed to assess alexithymia in patients suffering from HIV, HCV or HIV/HCV coinfection and observe major differences. We selected 153 subjects, excluding those with psychiatric diagnosis, cognitive impairment or opportunistic diseases, of whom 70 (46%) had HIV infection, 57 (37%) HCV infection and 26 (17%) HIV/HCV coinfection. For the evaluation of alexithymia, we used the Toronto Alexithymia Scale (TAS-20), a self-report questionnaire which allows the results to be assessed both on a dimensional level and on defined cutoff scores. Data analysis showed significant differences between monoinfected and coinfected subjects. The coinfected group had a mean score of 54.00 ±13.43, higher than HIV (48.11 ± 12.38) and HCV (48.28 ± 10.71) (p <0.05). Furthermore, we found clinically relevant scores (≥51) in 65.38% of coinfected subjects, in 42.85% of HIV and in 40.35% of HCV (p <0.05). Given the medical and behavioral correlates of alexithymia highlighted in the literature, we suggest that further investigations are needed to clarify the relationship between alexithymia and HIV/HCV coinfection.
