BACKGROUND Sodium valproate is widely used in the treatment of epilepsy in clinical practice. Most adverse reactions to sodium valproate are mild and reversible, while serious idiosyncratic side effects are becoming apparent, particularly hepatotoxicity. Herein, we report a case of fatal acute liver failure (ALF) with thrombotic microangiopathy (TMA) caused by treatment with sodium valproate in a patient following surgery for meningioma. CASE SUMMARY A 42-year-old man who received antiepileptic treatment with sodium valproate after surgery for meningioma exhibited extreme fatigue, severe jaundice accompanied by oliguria, soy sauce-colored urine, and ecchymosis. His postoperative laboratory values indicated a rapid decreased platelet count and hemoglobin level, severe liver and kidney dysfunction, and disturbance of the coagulation system. He was diagnosed with drug-induced liver failure combined with TMA. After plasma exchange combined with hemoperfusion, pulse therapy with high-dose methylprednisolone, and blood transfusion, his liver function deteriorated, and finally, he died. CONCLUSION ALF with TMA is a rare and fatal adverse reaction of sodium valproate which needs to be highly valued.

Objective To investigate the effect of exercise in thermal climates on the renal functions and explore the role of oxidative stress injury in the pathogenesis of exertional heat stroke (EHS). Methods Totally 187 young soldiers in the subtropical area of Southeast China were divided randomly into two groups. All subjects underwent 1.5km, 3km and 5km cross-country running under two different environmental conditions: normal temperature and normal humidity [temperature (26±2) ℃, humidity 50%±5%]; high temperature and high humidity [temperature (33±2) ℃, humidity 65%±5%], and each soldiers' blood samples were taken at pre and post running. The level of Cr, BUN, CK, CK-MB, LDH and SOD were measured by automatic biochemical analyzer. The levels of serum 8-OHdG was detected by enzyme-linked immunosorbent assay (ELISA). Results 1) After exercise, the Cr and BUN of the two groups increased, compared with the pre- exercise the differences were significant (P

Background Immune-tolerant chronic hepatitis B (CHB) patients awaiting assisted reproduction (AR) are required to initiate antiviral therapy because of laboratory safety concerns. The antiviral therapy in this group has not been well assessed. We sought to explore the efficacy and safety of the combination therapy (COM) of tenofovir (TDF) and telbivudine (LdT). Patients and methods In this open-label, randomized, controlled study, we enrolled and randomized hepatitis B virus e-antigen (HBeAg)-positive CHB patients awaiting AR into the study COM group and the control (TDF) group. The COM group received combination therapy of TDF and LdT, and the TDF group received a single treatment of TDF. The patients were followed up for at least 48 weeks. The primary endpoint was the proportion of patients with undetectable HBV DNA level at week 12. Results A total of 121 patients were recruited into the COM group (n=60) and the TDF group (n=61). The percentages of patients with undetectable HBV DNA levels were 90.0% (54/60) in the COM group and 67.2% (41/61) (P=0.002) in the TDF group at week 12; the percentages were 96.6% (58/60) in the COM group and 85.2% (52/61) in the TDF group at week 48 (P=0.028), respectively. HBeAg seroconversion occurred in 5/60 (8.3%) patients in the COM group and 2/61 (3.3%) patients in the TDF group at week 48 (P=0.233). Conclusion TDF and LdT combination therapy shows a rapid antivirological response in immune-tolerant CHB patients awaiting AR, which provide an alternative for this group at AR centers. However, the HBeAg seroconversion rate is unsatisfactory in the short term.
