[Show abstract][Hide abstract] ABSTRACT: Neridronate is a third generation bisphosphonate with established efficacy in metabolic bone disease. In this randomized, open-label study, 118 adults with β-thalassaemia and bone mineral density (BMD) Z scores ≤-2·0 were randomized 1:1-500 mg calcium with 400 international unis (iu) vitamin D daily or 500 mg calcium with 400 iu vitamin D daily plus neridronate 100 mg intravenously every 90 d. Significant increases in BMD at the lumbar spine and total hip were noted in the neridronate group at 6 and 12 months from baseline (P < 0·001), and values were significantly higher than the control group at both time intervals. Neridronate also significantly decreased serum bone alkaline phosphatase and C-telopeptide of collagen type 1 levels from as early as 3 months (P = 0·04 and P < 0·001, respectively), reaching significantly lower values at 12 months compared with the control group (P < 0·05). Reductions in back pain and analgesic use were also evident, starting 3 months from commencing treatment. Treatment was well tolerated by all patients. In this largest randomized trial in thalassaemia-induced osteoporosis to date, neridronate was safe and effective in reducing bone resorption and increasing BMD. The associated reduction in back pain and improved quality of life will encourage adherence to therapy. (Clinicaltrials.gov identifier NCT01140321.).

[Show abstract][Hide abstract] ABSTRACT: We report the case of an 8-year-old boy with a red cell membrane disorder who developed, soon after undergoing laparoscopic cholecystectomy and splenectomy, complete thrombosis of the right branch and a partial occlusion of the left branch of the portal vein. The child was affected by a right hemiparesis because of a hypoxic-ischemic disorder that occurred in the first hours of life and was heterozygous for the methylenetetrahydrofolate reductase gene mutation 677C-T. Intravenous heparin and aspirin were initiated on postoperative day 7. Heparin treatment was switched to the subcutaneous route after the first 24 hours. The symptoms subsided 3 days after the beginning of treatment, whereas complete resolution of portal vein thrombosis was observed 2 months later. A review of the literature is reported, and the possible pathogenetic mechanisms underlying portal vein thrombosis are discussed.
