Reactivation of hepatitis B virus following rituximab-based regimens: a serious complication in both HBsAg-positive and HBsAg-negative patients.
Hepatitis B virus (HBV) reactivation is a well-known complication of lymphoma treatment in the pre-rituximab era. This complication has not been as well studied, however, since monoclonal anti-CD20 antibody became the standard regimen for B cell lymphoma. In this retrospective study, 115 B cell lymphoma patients who received rituximab-containing therapy were analyzed. ⋯ Eight of ten HBV carriers without lamivudine prophylaxis experienced HBV-related hepatitis, including one fatal hepatic failure. Four (4.2%) of 95 HBsAg-negative patients developed de novo HBV-related hepatitis and two died of fulminant hepatitis. In conclusion, rituximab-based therapy may cause serious HBV-related complications and even death in both HBsAg-positive and HBsAg-negative patients.

Multicenter Study Clinical TrialImpact of infusion speed on the safety and effectiveness of prothrombin complex concentrate: a prospective clinical trial of emergency anticoagulation reversal.
Prothrombin complex concentrate (PCC) infusion is preferred for emergency reversal of coumarin therapy. Rapid infusion can potentially save crucial time; however, the possible impact of high infusion speed on PCC safety and effectiveness has not been delineated. In a prospective multinational clinical trial with 43 patients receiving PCC (Beriplex P/N) for emergency reversal of coumarin therapy, infusion speeds were selected by the investigators. ⋯ None of the evaluated thrombogenicity marker pharmacokinetic parameters was affected by infusion speed. Infusions in one patient with questionable hemostatic efficacy and another with a possibly PCC-related thromboembolic event were at moderate and slow speeds, respectively. This study provides the first direct evidence that Beriplex P/N can be rapidly infused for emergency coumarin therapy reversal without altering safety or effectiveness.

Review Case ReportsSheehan's syndrome with pancytopenia--complete recovery after hormone replacement (case series with review).
Reports of pancytopenia in patients with Sheehan's syndrome are rare, because the disorder is not commonly seen in western countries. A case series of pancytopenia in three patients of Sheehan's syndrome is presented. Three women aged 22, 30, and 34 years developed Sheehan's syndrome preceded by post partum hemorrhage. ⋯ Treatment with thyroxine and glucocorticoids resulted in complete recovery after attaining euthyroid and eucortisolemic state. Review of literature revealed the rarity of the disorder, with only four cases reported so far. Multiple anterior pituitary hormone deficiencies in Sheehan's syndrome are responsible for pancytopenia; replacement of thyroid and cortisol hormones results in complete recovery.
