Interferon alpha-induced hashimoto thyroiditis followed by transient graves disease in a patient with chronic HCV infection.

The case of a 37-year-old man with chronic hepatitis C virus (HCV) infection is presented. The patient had received a 6-month course of antiviral therapy with peg interferon alpha-2a and ribavirin, with concomitant clearance of hepatitis C virus ribonucleic acid (HCV-RNA) from serum at the end of treatment. Three months after the treatment course he developed clinical and laboratory features of hypothyroidism along with high titers of thyroid peroxidase antibodies.

Circulating osteoprotegerin and receptor activator of NF-kappaB ligand system in patients with beta-thalassemia major.

Osteoporosis represents an important cause of morbidity in patients with beta-thalassemia major, and its etiology is multifactorial. Thus, the aim of this study was to characterize the possible role of the osteoprotegerin (OPG) and receptor activator of the NF-kappaB ligand (RANKL) system in thalassemia-related bone loss. Serum concentrations of OPG, soluble RANKL (s-RANKL), markers of bone turnover, and lumbar spine bone mineral density (BMD) were measured in random samples of males (n = 29; mean age +/- SEM, 24.
