Influence of Cystic Fibrosis-Related Diabetes on Mental Health in Adults: A Single-Center Study

Coping and learning to Manage Stress with cystic fibrosis (CALM): A multisite telehealth randomized controlled trial to reduce depression and anxiety symptoms in adults with cystic fibrosis

BACKGROUND

Adults with cystic fibrosis (AWCF) have higher rates of depression and anxiety than comparable community members. This multisite randomized waitlist-controlled trial tested the efficacy of "Coping and Learning to Manage Stress with CF" (CALM), a 6-session+booster telehealth intervention to improve depression and anxiety symptoms (primary outcomes) and perceived stress, coping self-efficacy, and key health-related quality of life domains (secondary outcomes).

METHODS

AWCF reporting mild to severe symptoms of depression and/or anxiety were randomized to receive CALM immediately (immediate, n = 66) or after a 13-week delay (waitlist, n = 66). Group differences post-intervention and at 1-month were examined via linear mixed models. Maintenance of treatment gains from baseline to 3-month follow-up was examined using combined data from both groups. Effect size calculations using Cohen's d assessed treatment effect magnitude.

RESULTS

Compared to the waitlist group, those that received CALM immediately reported lower depression and anxiety symptoms post-intervention and at 1-month follow-up (ps<0.001). For depression there was a large effect size post-intervention (d = 0.85) and a medium effect size at 1-month follow-up (d = 0.70); anxiety had a medium effect size post-intervention (d = 0.65) and at 1-month follow-up (d = 0.66). The immediate group also reported significantly higher coping self-efficacy, less stress, and increased vitality post-CALM and at 1-month follow-up (ps<0.01). Treatment gains were maintained at 3-month follow-up for all outcomes.

CONCLUSIONS

CALM was efficacious for AWCF in reducing symptoms of depression, anxiety, and perceived stress while improving coping self-efficacy and vitality with evidence of treatment sustainability. Next steps are dissemination and implementation to CF psychosocial clinicians.

Cystic Fibrosis-Related Diabetes in Poland

Cystic fibrosis (CF) is the most common autosomal recessive inherited monogenic disease in Caucasians. As medical technology progresses and the quality of patient care improves, the survival time of patients with CF has increased, which results in more frequent comorbidities such as cystic fibrosis-related diabetes (CFRD). CFRD is the result of abnormal glucose metabolism characterized primarily by insulin deficiency, exacerbated periodically by insulin resistance. The aim of our study was to analyze the epidemiology of patients with CFRD in Poland on the basis of data collected from six CF treatment centers. Analyses were performed on 1157 CF patients who were treated at one of the six CF care centers. CFRD was diagnosed according to standard criteria. All data including demographics, types of CFTR mutations, CFRD duration, and microorganisms in the sputum were obtained from the patients’ medical history. Our study indicates that the prevalence of CFRD in Poland is 12.9%. CFRD was most often diagnosed between the ages of 11 and 20 (60% of patients), while 23% of patients were diagnosed between 21 and 30 years of age. Furthermore, we observed that approximately 3–5% of patients under the age of 10 had CFRD. We found out that the type of mutation did not affect the frequency of CFRD development. Factors that increased the risk of developing CFRD include underweight and chronic Pseudomonas aeruginosa infection. Due to the extended lifespan of CF patients, the number of CFRD patients is currently increasing. We believe that the results of our study may complement information from other studies or may be useful in planning health policy in Poland.

Cystic fibrosis-related diabetes: The patient perspective

Cystic fibrosis-related diabetes (CFRD) affects nearly 20% of adolescents and 40-50% of adults. However, the impact on patients and their families is poorly understood. Here, we examine how patients perceive CFRD and identify gaps in our understanding of the patient experience. Despite its relatively high prevalence, data suggest that many individuals are not aware of the possibility of developing CFRD or compare it to other types of diabetes. Annual oral glucose tolerance testing (OGTT) may serve as an opportunity to provide education and prepare individuals for the possibility of developing abnormalities in glucose tolerance. Many cite lack of awareness of CFRD as the most difficult part of the diagnosis. While factors such as older age and a strong support system promote acceptance, most individuals view the diagnosis negatively and struggle to balance the demands of diabetes with other obligations, including airway clearance, nebulizer therapies, supplementation nutrition, and administration of vitamins and medications. Relatively few people with CFRD monitor their blood glucoses consistently, which is attributed to time constraints or an attempt to avoid pain. In addition, many feel that they are not prone to hypoglycemia and are not concerned with long-term complications, anticipating that they will succumb to their pulmonary disease before these become problematic. The adolescent period presents unique challenges for adherence as children work to develop autonomy. Factors that promote CFRD adherence include incorporating management into daily CF routines and the support of knowledgeable providers to help develop an individualized approach to management. Diabetes technology has the potential to reduce treatment burden and improve glycemic control, but data in CFRD are limited, and additional study is needed. Given that CFRD is associated with a decline in health-related quality of life, it is critical that providers understand patients' perspectives and address gaps in understanding and barriers to management.
