NCT ID: NCT05676346 Completed - Clinical trials for Lower Urinary Tract Symptoms

Genetic DAO Deficiency and Lower Urinary Tract Symptoms

DAO-LUTS
Start date: October 11, 2022
Phase:
Study type: Observational

The aim of this study is to determinate the prevalence os genetic DAO deficiency in patients with lower urinary tract symptoms.

NCT ID: NCT03298568 Completed - Food Intolerance Clinical Trials

Study to Investigate the Effect of an Oral Diamine Oxidase Substitution (DAOsin) in Histamine Intolerant Patients on the Low Endogenous Diamine Oxidase Serum Activity

Start date: August 21, 2017
Phase: N/A
Study type: Interventional

DAOsin is a food supplement for special medical purpose for the treatment of food intolerance provoked by histamine intake. In this uncontrolled, interventional pilot study the effect of an oral diamine oxidase substitution (DAOsin) on the reduced endogenous diamine oxidase activity in histamine intolerant patients will be examined. Patients with a low endogenous diamine oxidase activity (below 10 Units/ml) take DAOsin for one month 3 times a day. During this month the diamine oxidase activity is tested biweekly. Afterwards a follow up period of one month without taking DAOsin follows. Again the diamine oxidase activity is tested biweekly.

NCT ID: NCT02418221 Completed - Clinical trials for Histamine Intolerance

A Provocation Study Using Biogenic Amines to Show the Efficacy of Oral Diamine Oxidase Supplementation

Start date: February 2014
Phase: N/A
Study type: Interventional

This study aims to define a provocation test for histamine intolerance (aka. biogenic amine intolerance syndrome) and test the capability of an oral enzyme supplementation to ameliorate this condition.
