Introduction

Cystic Fibrosis (CF) is a genetic disorder that affects primarily the lungs and digestive system. Despite its relatively low prevalence compared to other diseases, CF has a significant impact on individuals and their families. With advancements in medical science, our understanding of CF has deepened, leading to improved treatments and increased life expectancy. However, challenges remain, and the quest for a cure continues.[1,2].

CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene is responsible for producing a protein that regulates the movement of salt and water in and out of cells. When CFTR is faulty, it results in the production of thick, sticky mucus in the lungs and digestive system.In the lungs, this thick mucus obstructs airways, making it difficult to breathe and providing a breeding ground for bacteria, leading to recurrent lung infections and eventually respiratory failure. In the digestive system, the mucus blocks ducts in the pancreas, preventing digestive enzymes from reaching the intestines, which can lead to malnutrition and poor growth.[3,4].

Symptoms of CF vary from person to person but commonly include persistent coughing, wheezing, recurrent lung infections, poor weight gain despite a good appetite, and salty-tasting skin. Diagnosis often occurs in infancy through newborn screening or later in childhood or adulthood when symptoms become apparentManaging CF is complex and requires a multidisciplinary approach. Treatment aims to alleviate symptoms, prevent complications, and improve quality of life. This often involves a combination of medications, airway clearance techniques, exercise, and nutritional support.[5,6].

One of the main challenges in CF management is the constant threat of lung infections. Antibiotics are frequently used to treat infections, but over time, bacteria can become resistant, making infections harder to treat. Additionally, the thick mucus in the airways makes it difficult for antibiotics to penetrate deeply into the lungs.Another challenge is the nutritional aspect of CF. Individuals with CF often struggle to maintain a healthy weight due to malabsorption and increased energy requirements. Nutritional supplements and a high-calorie diet are typically prescribed, but achieving and maintaining optimal nutrition can be challenging 7,8].

Despite these challenges, significant progress has been made in the treatment of CF in recent decades. The development of CFTR modulator therapies, such as ivacaftor, lumacaftor, and tezacaftor, has revolutionized CF care. These drugs target specific defects in the CFTR protein, helping to restore its function and improve symptoms. Trikafta, a combination therapy approved by the U.S. Food and Drug Administration (FDA) in 2019, has been particularly transformative. It has shown remarkable efficacy in improving lung function and reducing exacerbations in individuals with CF, regardless of their specific CFTR mutations. In addition to pharmacological therapies, advances in airway clearance techniques, nutritional support, and lung transplantation have also contributed to improved outcomes for individuals with CF.While these advancements are promising, there is still no cure for CF. Research efforts are ongoing to better understand the underlying mechanisms of the disease and to develop more effective treatments.Gene editing technologies, such as CRISPR-Cas9, hold potential for correcting the underlying genetic mutations responsible for CF. Clinical trials investigating gene therapy approaches are underway, offering hope for a future where CF can be treated at its root cause.[9,10].

Conclusion

Cystic fibrosis remains a challenging disease, but advancements in research and treatment have significantly improved outcomes and quality of life for affected individuals. With continued dedication to scientific research and innovation, there is hope for a future where CF is no longer a life-limiting condition.
