Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of DIHYDROERGOTAMINE with potent CYP 3A4 inhibitors including protease inhibitors and macrolide antibiotics. Because CYP 3A4 inhibition elevates the serum levels of DIHYDROERGOTAMINE, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of these medications is contraindicated. (See also CONTRAINDICATIONS and WARNINGS section)

The PROMISE study: PROphylaxis of MIgraine with SEglor (dihydroergotamine mesilate) in French primary care. 
INTRODUCTION: Seglor capsules, a unique modified-release formulation of dihydroergotamine mesilate, have long been in clinical use in France for migraine prophylaxis. The aim of the PROMISE (PROphylaxis of MIgraine with SEglor) study was to establish the efficacy and tolerability of Seglor in the prevention of migraine in a general practice setting... CONCLUSION: These results support the effectiveness of Seglor in patients with migraine-related quality-of-life impairment. The findings of the PROMISE study also suggest that patients' quality of life should be assessed systematically before initiating a preventive treatment for migraine.
Comparison of intravenous valproate versus intramuscular dihydroergotamine and metoclopramide for acute treatment of migraine headache. [2001.11]
OBJECTIVE: To determine the effectiveness and tolerability of intravenous valproate for the acute treatment of migraine headache with or without aura (International Headache Society diagnostic criteria 1.1 and 1.2) compared with intramuscular metoclopramide 10 mg followed 10 minutes later by intramuscular dihydroergotamine 1 mg. BACKGROUND: Divalproex sodium is approved for prophylaxis of migraine headache. We studied the possible effectiveness of intravenous sodium valproate for the treatment of acute migraine headache. Valproate offers a treatment option for patients with migraine who recently have used a triptan or dihydroergotamine, theoretically avoiding the risk of drug interactions or cardiovascular complications... CONCLUSIONS: Intravenous valproate is similar in effectiveness to dihydroergotamine/metoclopramide as abortive therapy for prolonged moderate-to-severe acute migraine headache. Although the results were not statistically significant (P =.3635), intravenous valproate appears to offer a safe, effective, and well-tolerated treatment for patients with acute migraine. Relative to dihydroergotamine/metoclopramide, however, headache relief was not as likely to be sustained at 24 hours as with intravenous valproate.
Haemodynamic effects of three doses of dihydroergotamine during spinal anaesthesia. [2001.09]
We performed a randomized study comparing the haemodynamic effects of three doses of the vasopressor dihydroergotamine (DHE) (5, 10 and 15 microg x kg(-1)) in 30 ASA 1 and 2 patients, aged 53-87 yr, undergoing spinal anaesthesia. Non-invasive systolic arterial pressure (SAP), heart rate and central venous pressure (CVP) were recorded continuously for 25 min...

HELP-Apheresis in Diabetic Ischemic Foot Treatment (H.A.D.I.F) [Recruiting]
Diabetic foot (DF) is a common, severe and costly complication of diabetes. DF is underlied
by neuropathy, atherosclerosis of distal arteries and infection, which result in tissue
ulcers and necrosis. Alterations in microcirculatory function and in blood rheology may
concur in causing tissue damage.
In recent years there has been accumulating evidence that LDL apheresis (LA) does not only
reduce cholesterol but also has a series of pleiotropic effects that improve the
microcirculation, increasing peripheral tissue perfusion.
HADIF is a randomized, multicentric, prospective clinical study aimed at assessing the
effect of LDL apheresis treatment in association with traditional therapy for ulcers, in
patients with an ischemic diabetic foot ulcer (class I and II Texas Wound Classification
System)and peripheral vasculopathy not susceptible to revascularization. A total of 132
patients will be enrolled. Participants will be centrally randomized to receive traditional
therapy alone (TT) or in association with LA. TT includes standard medication of ulcers,
antiaggregant therapy and statins. LA will be performed with HELP system, for a total of 10
sessions in 9 weeks. The primary end-point of the study is ulcer healing; secondary
endpoints include improvements of peripheral oxygenation, resolution of pain, reduction of
circulating inflammatory markers, cardiovascular events during one year's follow-up.
This clinical Study has been approved by local EC on 25 may 2011 (Study number 1953).
TO BE NOTED: since diabetic patients in our "Diabetic-Foot UNIT" often presented foot ulcers
more severe than class II Texas, a formal amendment has been submitted to EC for recruiting
patients with diabetic foot ulcer of class III Texas. The amendment was already approved on
5 may 2012.
Exercise for Depression in Young People [Completed]
Exercise as an adjunct to routine treatment may be useful for helping young people recover
from distressing mental health problems, but they seldom get sufficient support to help them
to exercise. The reasons for this may be that services cannot agree on the benefits of
exercise, and the lack of reliable evidence showing the benefits of exercise in young people
who use mental health services. Compliance with prescribed exercise is generally low, but
the investigators think that relatively few young people will drop out of our specially
designed programme. The investigators have found that young 'healthy' people may respond
better if exercise is matched to their ability. The investigators are not sure if this would
work with young people with mental health difficulties, so the investigators want to test
it. The investigators have also found that our enabling exercise plan, with social support
and motivational coaching, helps people with depression to take part, and not to drop out.
The aims of our study are to see if exercise matched to their ability, with support in
taking part, helps young people recover from distressing mental health difficulties. The
investigators also want to ask young people how they feel about exercise as a part of their
recovery. The investigators want to see if motivational coaching can help ongoing
participation in exercise, and the investigators want to follow up the young people after
six months to see if they are still doing exercise. The investigators believe that this
study is important because it will help young people feel better about themselves, and
improve their quality of life. This is an important national public health goal and should
enable young people to grow into healthy adults, and maintain their health throughout
adulthood. If our study is successful, the investigators believe that it has the potential
to change the way in which mental health services deliver care to young people. If the
investigators can help young people feel better about themselves, and improve their general
health and well being through exercise, the investigators may reduce their reliance on
mental health services.
Research hypotheses A tailored exercise intervention will lead to significantly improved
mental health outcomes and reduced exercise attrition rates in young people with depression.
