RESUMO
This study retrospectively investigated the clinical features and risk factors of allergic reactions induced by oxaliplatin administration. This study investigated the incidence of allergic reactions and analysed the background and laboratory data in patients with colorectal cancer treated with oxaliplatin-based chemotherapy at Kyushu Medical Center between April 2012 and September 2012. A total of 62 patients were included in this study. The number of patients in the allergic and non-allergic groups was 7 and 55 respectively. The incidence of allergic reactions was 11.3%. We compared the patients' characteristics and laboratory data between the two groups and found that the average dose of dexamethasone in the allergic group was significantly lower than that observed in the non-allergic group (P = 0.0111). Furthermore, the incidence of allergic reactions in the group that received prophylaxis of less than 12 mg of dexamethasone was significantly higher than that observed in the group that received more than 12 mg of dexamethasone (P = 0.0103). In conclusion, a lower dexamethasone dose is a possible risk factor for allergic reactions induced by the administration of oxaliplatin; however, given the retrospective design used in this study, further validation of this finding is warranted.

Two viruses were isolated from bovine blood in the southernmost part of Japan in 1994 and 2001, respectively. Genetic analyses showed that the viruses were Batai virus of the genus Orthobunyavirus of the family Bunyaviridae. The sequencing of three genomic RNA segments of the Japanese and Malaysian Batai virus strains revealed that the M RNA segment of Batai virus had high sequence identity with that of Ngari virus. Our results indicate that Ngari virus is a genetic reassortant with S and L RNA segments from Bunyamwera virus and an M RNA segment from Batai virus.
