    Background: Chronic hepatitis C virus (HCV) is associated with extra hepatic autoimmune disorders, while peg-IFNa-2a/RBV combination therapy may exacerbate these conditions. Autoantibodies to cytoplasmic structures, called rod and ring particles (RR), have strong associations with these patients and are identified by HEp-2 cells. Objectives: Our purpose was to study the correlation of autoantibodies to cytoplasmic rod and ring particles in the serum of patients with chronic HCV infection with their response to standard therapy. Methods: Serum samples were gathered from 120 patients with HCV infection (40 naive treatments, 40 with sustained virological response (SVR), and 40 with relapse response) during peg-IFNa-2a/RBV combination therapy and analyzed for the presence of RR antibodies by IIF on commercially available HEp-2 cell substrate slides from Euroimmun (Lu beck, Germany). Results: Anti-rod and ring (anti-RR) autoantibodies were detected in only the serum of 1 out of 120 patients (0.8), which belonged to a patient (out of 40) with relapse response (2.5). No correlation was found between the types of response to peg-IFNa-2a/RBV combination therapy and the presence of anti-RR autoantibodies. Conclusions: The only HCV patient with RR autoantibodies previously had received IFN/ribavirin antiviral therapy. The presence of these autoantibodies is extremely rare in Iranian HCV patients. Further studies are warranted to determine the role of genetic background and geographical pattern in the prevalence of these novel autoantibodies worldwide. � 2016, Kowsar Corp

    The adult age occurs when somebody reaches 65 years of age. It consists of gradually destruction of the structure and organism of the body during a long period. It leads to transformation of structure and process of different organs, such as: turning the hair white, hair falling, skin wrinkling, visual and hearing reducing, back curving, muscle power reducing, memory and perception disordering and reducing in capacity and function of pulmonary and cardiovascular systems."nTheories presented in the field of the adult age consisting of: A) biological theories classified by three groups: 1. Immunity theory 2. Cellular aging theory 3. Free radical theory B) psychological theories Qsociological theories that are classified by four groups: 1. Theory of non-commitment 2. Activity theory 3. Continuity theory 4. Interaction theory"nEach of the above theories provides justifications regarding the aging process and it is of importance to be aware of those theories in order to establish an information network for practically determinations regarding the adult age
