| Summary: | Introduction. Patients with primary antibody deficiency (PAD) can complicate with liver disease. This study was performed in order to study the prevalence and causes of hepatobiliary diseases in Iranian patients with PAD.Material and methods. Sixty-two patients with PAD were followed-up and signs and symptoms of liver disease were recorded. All patients were screened for hepatitis C virus (HCV-RNA) and those patients with any sign of liver disease or gastrointestinal complaints were tested for Cryptosporidium parvum.Results. Clinical evidences of liver disease, including hepatomegaly, were documented in 22 patients (35.5%). Eight patients (13%) had clinical and/or laboratory criteria of chronic liver disease. Only one patient was HCV-RNA positive; he had stigmata of chronic liver disease and pathologic evidence of chronic active hepatitis with cirrhosis. Cryptosporidium parvum test was positive for one patient with hyper-IgM syndrome. In liver biopsy of patients with liver involvement, one had histological findings related to sclerosing cholangitis, and five had mild to moderate chronic active hepatitis with unknown reason.Conclusions. Chronic active hepatitis is the most common pathologic feature of liver injury in Iranian patients with PAD. Liver disease in PAD usually accompanies with other organ involvements and could increase the mortality of PAD. Whether this high rate of liver disease with unknown origin (75%) is the result of an unidentified hepatotropic virus or other mechanisms such as autoimmunity, is currently difficult to understand.
