Systematic review with meta-analysis: mortality in acute severe ulcerative colitis

BACKGROUND

Acute severe ulcerative colitis (ASUC) is a life-threatening condition. Mortality in ASUC decreased in published series but there is uncertainty as to whether this also applies to the real-life setting.

AIM

To perform a systematic review and meta-analysis of mortality in ASUC in studies from referral centres and in population-based studies, separately and combined. A second aim was to identify risk factors of mortality in ASUC.

METHODS

We searched pubmed and embase from 1998 to 2016, to identify studies that reported 3-month or 12-month mortalities of acute UC in adult patients treated in referral centres, and in population-based studies.

RESULTS

Six population-based studies with 741 743 patients and 47 referral centre-based studies with 2556 patients were included. The pooled 3-month and 12-month mortalities were respectively 0.84% and 1.01%. Advanced age was significantly associated with both 3 month and 12 month mortalities (OR = 1.15 per year, 95% CI: 1.10-1.20 and OR = 1.19 per year, 95% CI: 1.15-1.23 respectively). The pooled 3-month and 12-month mortalities were 0.78% and 0.85% in studies with median age of less than 50 and 2.81% and 4.17% in studies with median age of 50 or more, respectively. After adjustment for age, 3-month and 12-month mortalities did not differ between population-based and referral centre-based studies.

CONCLUSIONS

Mortality in acute severe ulcerative colitis is approximately 1%; it is higher in older patients. Efforts should be made to improve the care of elderly patients with severe UC.

Personalization of regorafenib treatment in metastatic gastrointestinal stromal tumours in real-life clinical practice

Background:

Regorafenib (REG) has now been approved as the standard third-line therapy in metastatic gastrointestinal stromal tumour (GIST) patients at the recommended dose and schedule of 160 mg once daily for the first 3 weeks of each 4-week cycle. However, it has a relevant toxicity profile that mainly occurs within the first cycles of therapy, and dose and schedule adjustments are often required to reduce the frequency or severity of adverse events and to avoid early treatment discontinuation. To date, large amounts of data on the use of REG in metastatic GIST patients in daily clinical practice are not available, and we lack information about how this treatment personalization really affects the quality of life (QoL) of patients. The aim of the present retrospective study is to build a comprehensive picture of all alternative REG strategies adopted in daily clinical practice for use in metastatic GIST patients.

Methods:

Metastatic GIST patients treated with dose adjustment or alternative schedules of REG at seven reference Italian centres were retrospectively included.

Results:

For a total of 62 metastatic GIST patients, we confirmed that REG treatment adjustment is common in clinical practice and that it is very heterogeneous, with approximately 20 different strategies being adopted. Independent of which strategy is chosen, treatment personalization has led to a clinical benefit defined as complete or partial resolution of side effects in almost all patients, affecting the duration of REG treatment.

Conclusions:

The personalization of REG, even if it is heterogeneous, seems to be crucial to maximize the overall treatment duration.
