NFVIs, especially those due to V. vulnificus, demonstrate high morbidity and mortality. Persons with liver disease should be advised of the risks associated with seawater exposure if a wound is already present or is likely to occur. Clinicians should consider Vibrio species as an etiologic agent in infections occurring in persons with recent seawater exposure, even if the individual was only exposed during recreational marine activities. Immediate antibiotic treatment with aggressive monitoring is advised in suspected cases.

Summary Background Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Aim To report incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) in the tofacitinib UC programme. Methods DVT and PE were evaluated from one phase 2 and two phase 3 induction studies, one phase 3 maintenance study and an ongoing, open‐label, long‐term extension (OLE) study (September 2018 datacut). Data were analysed in induction, maintenance and overall (patients receiving ≥ 1 dose of tofacitinib 5 or 10 mg b.d. in any phase 2, 3 or OLE study) cohorts. Results 1157 patients (2404 patient‐years’ exposure; ≤ 6.1 years’ tofacitinib treatment) were evaluated in the overall cohort. In induction, one placebo‐treated patient had DVT and one had PE; no tofacitinib‐treated patients had DVT/PE. In maintenance, one placebo‐treated patient had DVT and one had PE; no tofacitinib‐treated patients had DVT/PE. In the overall cohort, one patient had DVT (incidence rate [patients with events/100 patient‐years; 95% CI]: 0.04 [0.00‐0.23]); four had PE (0.16 [0.04‐0.41]); all received predominant dose tofacitinib 10 mg b.d.; all had venous thromboembolism risk factors alongside UC. Conclusions In this post hoc analysis of patients with UC, during tofacitinib exposure, one patient had DVT and four had PE, all during the OLE study, on predominant dose 10 mg b.d. (83% of overall cohort patients received predominant dose 10 mg b.d.) with venous thromboembolism risk factors. This analysis is limited by small sample size and limited drug exposure; further studies are needed. ClinicalTrials.gov: NCT00787202, NCT01465763, NCT01458951, NCT01458574, NCT01470612.

Validation studies of claims data published in the English language in the Asia-Pacific region are very limited. Given the increased reliance on administrative health care databases for pharmacoepidemiology and the need for ensuring the credibility of results from such data, additional support for the conduct of validation research of claims data in the Asia-Pacific region is needed.
