NCT ID: NCT03737630 Not yet recruiting - Cystic Fibrosis Clinical Trials

Inspiratory Muscle Training in Individuals With Cystic Fibrosis

Start date: December 2018
Phase: N/A
Study type: Interventional

Cystic fibrosis is a genetic disease that affects some organs of the human body. Among them, the lungs tend to be the most affected due to the accumulation of mucus in the airways, which in addition to avoiding the passage of air, favors pulmonary infections. With the evolution of the condition, secondary complications arise, such as postural changes, decreased respiratory muscle strength, decreased functional capacity and, consequently, quality of life. Therefore, respiratory muscle training may be an intervention that improves the respiratory condition of these individuals, allowing an improvement in the quality of life and may delay the evolution of respiratory symptoms. Thus, this study aims to investigate a home protocol of respiratory muscle training on respiratory muscle strength, lung function, quality of life, posture and functional capacity in adolescents and adults with cystic fibrosis. The researchers believe that the training can cause an improvement in the studied variables, and can be inserted in the usual treatment of these patients.

Molecular Diagnosis of Respiratory Viral Infections on Sputum From Cystic Fibrosis Patients

Start date: October 3, 2018
Study type: Observational

The main objective of this project is to evaluate the agreement between nasopharyngeal and sputum specimens in terms of detection of viral infection in Cystic Fibrosis (CF) participants.This is a 12-month national, multicenter prospective study (7 centers). Inclusions concern CF participants (children or adults) with signs of acute respiratory infection seen in consultation or hospitalized in their CF Research Center. A molecular viral multiplex search is performed on both nasopharyngeal and expectoration collected samples for each included participant. Determination of viral detection agreement between the two CF respiratory samples is then performed.

NCT ID: NCT03734822 Enrolling by invitation - Cystic Fibrosis Clinical Trials

Comparative Analysis of CO2 Monitoring Methods in Patients With CF Undergoing General Anesthesia

Start date: March 10, 2016
Phase: N/A
Study type: Interventional

Four methods are routinely used to monitor CO2 in patients. End tidal CO2 (EtCO2) is monitored through the endotracheal tube during general anesthesia. CO2 is also monitored in other healthcare settings transcutaneously (TCO2), via finger stick capillary CO2 (CapCO2), and arterial blood gas (ABG). The purpose of this study is to perform all four measurements simultaneously during general anesthesia to identify which measure provides the most accurate data with the least amount of patient risk.

NCT ID: NCT03734744 Not yet recruiting - Cystic Fibrosis Clinical Trials

PK/PD of Vitamin D3 in Adults With CF

Start date: November 1, 2018
Phase: N/A
Study type: Interventional

Despite the extensive literature on adverse clinical outcomes associated with vitamin D deficiency, there are currently no proven treatment strategy that effectively achieves and maintains optimal serum vitamin D status in cystic fibrosis (CF) patients. For the treatment of vitamin D deficiency, CF Foundation currently recommends 2,000 IU daily. However, because achieving adequate serum 25(OH)D levels is a challenge in CF, higher doses of vitamin D may be necessary to reach and maintain vitamin D sufficiency. Poor oral bioavailability of ergocalciferol has been demonstrated in CF patients, which may potentially also be an issue with cholecalciferol. In order to optimize the treatment of vitamin D deficiency in CF, the kinetic disposition must be well understood. However, there are very few data currently available describing the kinetics of both vitamin D and 25-hydroxyvitamin D, and to the investigator's knowledge, no studies have yet characterized the pharmacokinetic disposition of vitamin D and its metabolites in cystic fibrosis. Addressing this issue is crucial in effectively and safely correcting vitamin D deficiency in CF.

Validation of a Predictive Score for HAST

Start date: October 29, 2018
Study type: Observational

Patients with chronic lung diseases travelling by plane often suffer with symptoms related to lower oxygen levels they are exposed to while flying. Therefore, patients with respiratory conditions are routinely assessed to establish if they need supplemental oxygen in flight. A hypoxic altitude simulation test (HAST) is often part of this assessment and consists in having patients breathe a oxygen/nitrogen blend with a lower oxygen concentration compared to normal room air, simulating in-flight conditions. Oxygen levels are measured before and after the test through a blood sample (from the earlobe or an artery in the wrist) and with a finger probe. In-flight oxygen is required if the oxygen level in the blood is lower than 6.6 kPa. HASTs are time consuming, costly, and require a dedicated hospital appointment. Using historical data, we developed scores based on capillary blood gas (blood sample from the earlobe), diagnosis and sex to predict the outcome of the HASTs. We validated the proposed scores in a separate historic cohort of patients and showed it had good concordance with the HASTs results. In this study, we want to confirm prospectively if the score, based on blood results (venous and/or earlobe), can predict the outcome of the HASTs and therefore reduce the number of tests performed, travel time for patients, and costs for the NHS. All patients, aged 18 or older, who are having a HAST for clinical purposes at the cardio-respiratory lab at Leeds Teaching Hospital NHS Trust will be invited to take part in the study. We will record diagnosis, results of HAST and previous spirometry from the medical notes, perform a spirometry if not done in the previous 12 months and collect a blood sample (one tube, 4 mls). With these data, we will calculate the score and assess its agreement with the outcome of the HAST. Each participant's involvement in the study will last for approximately 90-120 minutes, which is the normal duration of a HAST. We aim to include up to 280 subjects in the study.

NCT ID: NCT03724955 Not yet recruiting - Clinical trials for Cystic Fibrosis Related Bone Disease

Pilot E2 for Hypogonadal Women With CFBD

Start date: December 2018
Phase: Phase 4
Study type: Interventional

The study is a prospective, double blinded, placebo controlled, randomized study to evaluate the effects of daily oral estrogen supplements on bone health, sexual and reproductive health, quality of life and markers of inflammation and lung function when given to hypogonadal women with Cystic Fibrosis related Bone Disease (CFBD).

NCT ID: NCT03713437 Not yet recruiting - Clinical trials for Cystic Fibrosis-related Diabetes

Measurement of Beta Cell Death in Individuals With Cystic Fibrosis

Start date: November 2018
Study type: Observational

This study evaluates the feasibility of using differentially methylated insulin DNA, a biomarker of beta cell death, in determining the time course of beta cell death and development of diabetes in people with cystic fibrosis. Study participants with cystic fibrosis and healthy control participants will have a blood sample drawn in order to measure the levels of differentially methylated insulin DNA.

NCT ID: NCT03710538 Not yet recruiting - Cystic Fibrosis Clinical Trials

The Effect of a Pre-meal Snack and/or Exercise on Post-prandial Glycemic Excursions in Adults With Cystic Fibrosis

Start date: October 15, 2018
Phase: N/A
Study type: Interventional

The investigators aim to test the feasibility and effectiveness of a pre-meal snack to reduce the postprandial glycemia (PPG) excursion after a breakfast consumption in adult patients with cystic fibrosis (CF). The investigators also want to investigate the impact of a postprandial exercise to reduce the PPG excursion. An improvement in PPG excursions can improve the condition of CF patients primarily by delaying the onset of cystic fibrosis related diabetes (CFRD) and / or by reducing the risk of lung function loss.

NCT ID: NCT03699982 Recruiting - Cystic Fibrosis Clinical Trials

Resting Energy Expenditure in Patients With Cystic Fibrosis: A Pilot Study

Start date: October 10, 2018
Phase: N/A
Study type: Interventional

Cystic fibrosis is an inherited disorder that causes severe damage to the lungs, digestive system, and other organs in the body. Individuals with cystic fibrosis often have poor weight gain and growth that can negatively impact health further by worsening lung function. Additionally, persons with the disease typically need more than the usual calories on a daily basis. Most institutions estimate these patients' caloric needs using weight, age, and sex based mathematical formulae. However, numerous studies show that use of these formulae often yields inaccurate caloric values. Use of indirect calorimetry may give more accurate estimates of caloric needs in patients with cystic fibrosis. The aim of our study is to assess the accuracy of caloric estimates generated using one such widely used mathematical formula, the Harris-Benedict equation, and to compare this calorie value with that obtained from indirect calorimetry testing in pediatric and adult patients with cystic fibrosis. Study investigators will use the newly calculated caloric requirements in dietary counseling. Changes in weight and lung function after 3 months will be compared to participants' historical changes.
