Treatment

Treatment HCFA TEAM February 15, 2023

From the first moment of diagnosis, patients with CF are followed for life in a specialised Cystic Fibrosis centre and undergo a combination of time-consuming treatments on a daily basis. Patients’ daily struggle requires dedication and discipline. For patients in the final stages of respiratory failure, the only chance of survival is a lung transplant.

Symptomatic treatments

Cystic fibrosis patients follow a combination of time-consuming daily treatments that last 3-4 hours each day and follow a strict medical care protocol. They also require regular hospitalisation at a specialist CF centre.

The main aim of the treatments is to prevent and treat respiratory infections that lead to respiratory failure, but also to relieve the symptoms of the disease. They also aim to keep the lungs in particular, but also the patient’s body in general, in the best possible condition.

Physiotherapy helps to mobilise and remove the thick secretions and sputum that accumulate in the airways of patients’ lungs. It is done on a daily basis and its frequency and duration vary with each patient. There are various techniques that are used, such as autogenous drainage, active cycle breathing techniques, positive expiratory pressure with devices such as PEP mask, flutter, aerobics, acapella, etc.

In combination with physiotherapy, frequent exercise helps to mobilise the mucus in patients’ lungs, strengthen their musculoskeletal system and improve their physical condition.

Patients receive daily medication through inhalation into a nebuliser, which is a device that turns drugs into a cloud. These drugs can be either bronchodilators, mucolytics to break down mucus (Dornase alpha), or antibiotics (tobramycin, azreonam, colistin, levofloxacin, etc.) to keep the microbial load in the patients’ lungs low.

Patients need to follow a diet rich in calories, fat and protein in order to maintain a good weight and good nutrition. To improve the absorption of nutrients in food, they take daily pancreatic enzymes with every meal or snack. Enzymes are essential for breaking down food into components that can be absorbed by the body for normal digestion.

Due to exacerbations of the disease, patients are often hospitalized for about 2-3 weeks in specialized Cystic Fibrosis Centers, where they receive intravenous treatments to treat respiratory infections or other complications of the disease.

Due to malabsorption many patients take ABDEK vitamin preparations, but also dietary supplements. Also some patients are given insulin to treat Cystic Fibrosis Diabetes Mellitus. Various treatments are used to treat chronic sinusitis, such as nasal washes with sea water, antihistamines, corticosteroids and antibiotics. Nasal polyps can be treated surgically, but recurrences are very common. Patients are also recommended to hydrate frequently and eat salty foods, especially during the summer months, to avoid dehydration.

Innovative CFTR Modulators treatments

Innovative CFTR modulator therapies (CFTR Modulators) act on the causes of the disease. They improve the function of the defective CFTR gene, which causes Cystic Fibrosis, and “freeze” the disease, significantly slowing its progression.

Thanks to innovative CFTR modifier therapies, the health and quality of life of patients with Cystic Fibrosis has improved significantly in recent years, and their survival rate is gradually increasing.

In 2012, the first innovative CFTR Modulator therapy Ivacaftor was launched under the trade name Kalydeco, which targets the causes of the disease and is administered to a small number of patients, as it targets a limited number of gene mutations. A few years later, the next two CFTR treatments lumacaftor/ivacaftor (Orkambi) and tezacaftor/ivacaftor (Symkevi) were released, targeting a larger number of gene mutations. These treatments can be given to patients who are homozygous for the most common gene mutation F508del, but they do not have the same efficacy as the first treatment.

In October 2019, the fourth in a series of CFTR Modulator therapy of the triple combination ivacaftor/tezacaftor/elexacaftor/elexacaftor in combination with ivacaftor, branded Trikafta (Kaftrio in Europe), was approved in the US, which affects 90% of Cystic Fibrosis patients worldwide. This treatment can be given to patients who are heterozygotes with one F508del mutation and those who are homozygotes with two F508del mutations. After pressure from the Hellenic Cystic Fibrosis Association, in April 2020, the early access programme for the revolutionary treatment that “freezes” the disease was launched in Greece, saving the lives of 30 critically ill Greek patients. In Europe, the new treatment was approved by the European Medicines Agency (EMA) in August 2020 for patients aged 12 years and older under the name Kaftrio. Kaftrio treatment is given in combination with Kalydeco. The innovative treatment is available to all eligible patients with Cystic Fibrosis in Greece. Thanks to the treatment, the vast majority of Cystic Fibrosis patients have regained their breath, as their respiratory function and general health has improved significantly. Based on an analysis of data from the US Cystic Fibrosis Patient Registry (CFFPR) in 2022, Kaftrio/Kalydeco treatment not only improved patients’ lung function, but also reduced the risk of exacerbations by 77% compared to before the start of treatment. It also reduced the risk of lung transplantation by 87% and the risk of death by 74%, compared with 2019 American Registry of C.I. data. This demonstrates that taking Kaftrio/Kalydeco has a very significant impact on the course of respiratory function in Cystic Fibrosis patients.

Gene therapy

Gene therapy aims to replace the defective CFTR gene in the airway cells of patients with Cystic Fibrosis and is aimed at all patients, regardless of their mutations. At present, gene therapy is in the clinical trials stage, with further developments expected in the coming years.

Lung transplantation

For patients with Cystic Fibrosis who are not eligible for an innovative CFTR modifier therapy or do not have the expected results from innovative therapies and are in the final stages of respiratory failure, the only survival option is lung transplantation.

The transplant is carried out if they are approved for inclusion on the transplant list. To be included on the list, a patient must meet certain criteria, which are established through a series of tests during pre-transplant screening. When a suitable graft is found in time, the transplantation procedure takes place. Before and after the transplantation, the patient is given medication to prevent the rejection of the transplant.

The monitoring of the transplant patient never stops and is done every three or six months, depending on the patient’s condition. Several times hospitalisation is needed in case of any deterioration of respiratory function or if any symptoms from the respiratory system occur. A major issue facing a transplant patient is graft rejection, as well as frequent and serious infections. Based on the statistics, the median survival for lung transplantation in patients with Cystic Fibrosis is longer compared to other respiratory diseases, due to the young age of Cystic Fibrosis patients transplanted.

Until 2014, there was no stable long-term programme for lung transplantation in Greece. With pressure from the Hellenic Cystic Fibrosis Association in cooperation with the State and the competent bodies, a transnational cooperation agreement between the National Transplantation Organisation (EOM) and the Austrian Transplant Centre (AKH) was signed in 2014. Thanks to this agreement, more than 25 patients with Cystic Fibrosis, as well as patients with other respiratory diseases, were able to undergo successful lung transplantation in Austria from 2015 to 2019.

In June 2019, the transnational cooperation agreement between Greece and Vienna, under which Greek patients were referred to the AKH hospital for lung transplantation, expired. Since 2019, the National Lung Transplant Program has been launched in Greece at the Onassis Cardiosurgery Center with the support of the Onassis Foundation. This is where all Greek patients who need a lung transplant are referred to. Between 2020 and November 2022, 18 lung transplants were performed in the Greek programme. The first two successful lung transplants in Cystic Fibrosis patients were performed in 2022.

In Greece, organ donation rates are low. Lungs in particular require even more effort than other organs, as they are a fragile and sensitive graft. The timely identification of potential donors in hospital ICUs and the timely procurement of organs is a difficult process, which requires a well-organised health system with a sufficient number of qualified scientists. To become an organ donor, a person must be certified in the ICU as having brain death, which is an irreversible condition. Organ donation is the ultimate act of love and altruism, as one donor can save eight of our fellow human beings.

The Hellenic Cystic Fibrosis Association participates in the national effort to increase the number of organ donors in Greece with the successful campaign “Breath unlimited – Be a life donor”. The Association created the campaign from 2021, under the auspices of the National Transplantation Organisation, with the aim of raising public awareness of organ donation and transplantation.

Campaign communication actions: TV video spots, murals in major hospitals of the country with stories of real transplanted Greek patients with C.I. who won the second chance in life, awareness concert.

Honorary Supporter of the Campaign is the President of the Republic.

The campaign has been awarded the Silver Healthcare Award 2021, as in 2020-2021 during covid-19 it contributed to a tripling of organ donor registrations, with 631 new registrations in the National Transplantation Agency’s Organ Donor Registry.
