Tacrolimus as a Promising Drug for Epistaxis and Gastrointestinal Bleeding in HHT.

ABSTRACT:

Background

Hereditary Hemorrhagic Telangiectasia (HHT) is a vascular autosomically inherited rare disease. Epistaxis (nose bleeds) is the most common symptom in HHT, leading to anemia and affecting the patient's quality of life. In addition to epistaxis, gastrointestinal bleeding (GI), more often at older ages, may lead to severe anemia and the need for blood transfusions. Thus, finding drugs to control both types of bleeding is a primary necessity in HHT.

Methods

A cross-sectional observational study was conducted in a series of 11 HHT patients treated with low tacrolimus doses (0.5-2 mg/day) on an off-label prescription basis. Patients showed refractory bleeding to previous treatments. The epistaxis severity score (ESS) and hemoglobin levels were the parameters used to evaluate the impact of tacrolimus. The occurrence of side effects was also recorded.

Results

Tacrolimus was well tolerated in all of the patients except 2 (who stopped the treatment). The remaining patients tolerated the treatment, with a general improvement in their health condition. Epistaxis was significantly reduced when comparing the ESS before and after the treatment. Hemoglobin levels significantly increased, overcoming the anemia, during the course of the treatment.

Conclusion

Tacrolimus at low doses should be considered as a promising treatment for epistaxis and gastrointestinal bleeding in HHT.

Project description:ImportanceEpistaxis is the greatest cause of morbidity in patients with hereditary hemorrhagic telangiectasia (HHT); because of this, a validated epistaxis-specific quality-of-life instrument for HHT should be made available.ObjectiveTo develop and validate an epistaxis-specific quality-of-life patient-reported outcome measure for HHT.Design, setting, and participantsThis survey study focused on the development and validation of the Nasal Outcome Score for Epistaxis (NOSE) in HTT (NOSE HHT) outcome measure with data prospectively collected from December 10, 2019, to March 15, 2020. A total of 401 patients were recruited from within the Cure Hemorrhagic Telangiectasia online patient advocacy social media network, the Washington University HHT Center of Excellence, and a randomized clinical trial investigating an intranasal timolol gel for HHT-associated epistaxis.Main outcomes and measuresFace and content validity, factor analysis, internal consistency as measured through Cronbach α, construct validity, responsiveness to change, and minimal clinically important difference.ResultsThe NOSE HHT was developed and validated with a possible score ranging discretely from 0 to 4 for each of the 29 items and a total score ranging continuously from 0 to 4 after dividing by the total number of items answered. A total of 401 participants completed the NOSE HHT. Factor analysis identified 3 factors that matched the a priori specified subgroups of particular aspects of life affected by HHT-associated epistaxis: physical problems (mean [SD] magnitude, 1.59 [0.83]), functional limitations (mean [SD] magnitude, 1.28 [0.84]), and emotional consequences (mean [SD] magnitude, 1.95 [1.02]). The instrument had high internal consistency with an overall Cronbach α of 0.960. Convergent validity determined the total NOSE HHT score to be a strong predictor of disease severity; total NOSE HHT score can be split up into the following epistaxis severity categories: mild (0-1), moderate (1.01-2), and severe (>2). The instrument was found to be sensitive to change, and the minimal clinically important difference for the total NOSE HHT score was 0.46.Conclusions and relevanceEvaluation of the consistency, reliability, and responsiveness of the NOSE HHT survey found it to be a valid instrument to assess severity and change in epistaxis. Study results suggest that the NOSE HHT survey is clinically applicable and useful as an outcome measure of future HHT-associated epistaxis trials.

Project description:BackgroundEpistaxis is the most common symptom of hereditary hemorrhagic telangiectasia (HHT), affecting more than 98% of adults with HHT, with significant impact on quality of life. Floseal® has been shown to be effective for the management of anterior epistaxis, but has yet to be thoroughly evaluated in this population. Our goal was to evaluate the efficacy of Floseal® for managing acute anterior epistaxis in patients with HHT.MethodsA pilot prospective clinical trial was conducted at two tertiary referral centres, St. Michael's Hospital, Toronto, Canada and The Ottawa Hospital, Ottawa, Canada. All patients with HHT presenting with acute anterior epistaxis to the two study centres, who enrolled in the study, received Floseal® treatment. The primary outcome measures were achievement of hemostasis and changes in the Epistaxis Severity Score (ESS) between baseline and one-month follow up. Secondary outcome measure included clinical assessment of the nasal cavity.ResultsSeven patients were included in the final analysis. All patients underwent treatment of anterior epistaxis with Floseal® and achieved control of epistaxis within 15-min post-application. Application of Floseal® was well tolerated, with patients reporting a pain score of 3 ± 3.13 out of 10. There was no statistically significant difference noted in ESS scores pre-treatment and one-month follow up, 6.27 ± 2.42 vs. 4.50 ± 2.44, p = 0.179. There was a significant improvement clinically on exam of the nasal cavity between baseline and at one-month follow up, indicated by a decrease in the clinical assessment score, 17.29 ± 7.70 vs. 9.57 ± 7.81 (p = 0.0088).ConclusionsPatients with HHT presenting with acute epistaxis were able to achieve hemostasis with one application of Floseal®, with the procedure being very well tolerated with minimal pain. Although there was no significant change in ESS scores, clinical assessment of the nasal cavity revealed significant improvement at one-month follow up post treatment with Floseal®.Trial registrationThis multi-centered prospective clinical trial was registered with ClinicalTrials.gov ( NCT02638012 ). Registered on December 22, 2015.

Project description:BackgroundUpper gastrointestinal (GI) bleeding is one of the most common, high risk emergency disorders in the western world. Almost nothing has been reported on longer term prognosis following upper GI bleeding. The aim of this study was to establish mortality up to three years following hospital admission with upper GI bleeding and its relationship with aetiology, co-morbidities and socio-demographic factors.MethodsSystematic record linkage of hospital inpatient and mortality data for 14 212 people in Wales, UK, hospitalised with upper GI bleeding between 1999 and 2004 with three year follow-up to 2007. The main outcome measures were mortality rates, standardised mortality ratios (SMRs) and relative survival.ResultsMortality at three years was 36.7% overall, based on 5215 fatalities. It was highest for upper GI malignancy (95% died within three years) and varices (52%). Compared with the general population, mortality was increased 27-fold during the first month after admission. It fell to 4.3 by month four, but remained significantly elevated during every month throughout the three years following admission. The most important independent prognostic predictors of mortality at three years were older age (mortality increased 53 fold for people aged 85 years and over compared with those under 40 years); oesophageal and gastric/duodenal malignancy (48 and 32 respectively) and gastric varices aetiologies (2.8) when compared with other bleeds; non-upper GI malignancy, liver disease and renal failure co-morbidities (15, 7.9 and 3.9); social deprivation (29% increase for quintile V vs I); incident bleeds as an inpatient (31% vs admitted with bleeding) and male patients (25% vs female).ConclusionOur study shows a high late as well as early mortality for upper GI bleeding, with very poor longer term prognosis following bleeding due to malignancies and varices. Aetiologies with the worst prognosis were often associated with high levels of social deprivation.
