Dysfunctional coping is related to impaired skin-related quality of life and psychological distress in patients with neurofibromatosis type 1 with major skin involvement

Quality of Life in Children with Neurofibromatosis Type 1: Agreement between Parents and Patients, and the Role of Disease Severity and Visibility

BACKGROUND

Neurofibromatosis type 1 (NF1) is a genetic disorder that affects multiple systems in the body, often leading to physical disfigurements and a wide range of clinical symptoms. This study aims to investigate the relationship between NF1 severity and visibility and the quality of life (QoL) in children.

METHODS

The Pediatric Quality of Life Inventory (PedsQL) and a modified version of the Ablon scale were used to assess QoL and NF1 severity and visibility, respectively. Self-reported and parent-reported QoL scores were compared, and the associations between NF1 severity/visibility and QoL were explored.

RESULTS

Thirty-eight pediatric NF1 patients and their parents were enrolled. QoL scores did not differ significantly between patient self-reports and parent reports. However, correlational analyses revealed that higher NF1 severity was associated with lower physical QoL in patients, and greater NF1 visibility was linked to lower physical and social QoL. For parents, higher NF1 severity correlated with lower school functioning, whereas NF1 visibility did not show a significant correlation with QoL.

CONCLUSION

The severity and visibility of NF1 have distinct impacts on various aspects of QoL in children, highlighting the need for tailored interventions that address both physical and psychological challenges. These findings underscore the importance of comprehensive care approaches in managing NF1 in pediatric populations.

The impact of cutaneous neurofibromas on quality of life and mental health in neurofibromatosis type 1

The skin manifestations of neurofibromatosis 1 significantly reduce health-related quality-of-life. However, data on the utility of existing surveys in capturing neurofibromatosis 1 skin treatment outcomes are lacking. This quantitative study examined the relationship between clinician-rated severity and visibility and patient-rated itch and quality-of-life (QoL) to (1) establish baseline levels of skin- and condition-specific-related QoL, itch, depression and anxiety; (2) identify patient concerns to inform the development and evaluation of skin interventions; and (3) compare the sensitivity of different QoL measures. Validated scales included Skindex-29, Dermatology Life Quality Index (DLQI), Neurofibromatosis 1-adult quality-of-life (NF1-AdQOL) questionnaire, and the Hospital Anxiety and Depression Scale (HADS). We recruited 100 participants (response rate: 95%). Of these, 42% reported itch and 23% had probable clinical anxiety. Our cohort had higher levels of anxiety and total HADS scores compared to a control population. Using multivariate regression analysis, increasing visibility significantly predicted poorer QoL using the Skindex-29, NF1-AdQOL, and DLQI (p < 0.05); and itch significantly predicted worse QoL in Skindex-29 and NF1-AdQOL (p < 0.05). The highest mean scoring questions in Skindex-29 and NF1-AdQOL concerned worry about worsening skin disease and embarrassment. The highest mean scoring questions in DLQI were regarding itch, pain, and embarrassment. Items asking specifically about cutaneous neurofibromas (cNF) scored higher than comparable skin-specific questions (t-test p value <0.05). In summary, this study provides insights into the factors contributing to impaired QoL, anxiety, and mood in NF1 patients with cutaneous neurofibromas. Key factors identified for use in cNF measures include visibility, itch, anxiety, embarrassment, fears of worsening skin disease, and cNF-specific questions.

Self-Esteem and Coping Strategies in Adolescent Cancer Patients during the Period of Illness and Follow-Up

The importance of self-esteem during the course of oncological illness has been well-documented by some previous studies. However, data assessing its association with various coping strategies, especially considering the period of illness, are still scarce. The objective of this study is to analyze the differences in coping strategies among oncological adolescents, taking into account their self-esteem, illness period, age, and sex. A total of 201 oncological patients between the ages of 12 and 17 from three different Spanish cities were included in this study. All of them were asked to answer a tailored questionnaire, encompassing information about age, sex, and illness period. Additionally, the coping strategies were measured using the ACS scale, while self-esteem was evaluated using the SENA questionnaire. The results demonstrated that male adolescents and older individuals exhibited higher levels of self-esteem. The main coping strategies associated with higher self-esteem were "ignore the problem", "focus on positive", "physical recreation", and "wishful thinking" both during the treatment and the follow-up phases. We conclude that higher self-esteem is associated with some of the coping strategies such as "focus on positive", "ignore the problem", and "wishful thinking". Sociodemographic variables influence the relationship between self-esteem and coping strategies, but no differences were found regarding the period of illness.

cNF-Skindex in Adults Living with Neurofibromatosis 1: Severity Strata in France and Validation in United States Adults

Cutaneous neurofibromas (cNF) contribute to the impairment of QOL in individuals with neurofibromatosis 1. The cNF-Skindex, validated in a French population, specifically assesses the cNF-related QOL. In this study, we first defined severity strata using an anchoring approach on the basis of patient's burden. In total, 209 patients answered the anchor question and the cNF-Skindex. We tested the agreement among the three strata, generated by all potential couples of cut-off values of the cNF-Skindex and the three strata defined in the anchor question. The cut-off values 12 and 49 provided the highest Kappa value (κ = 0.685, 95% confidence interval = 0.604-0.765). Second, we validated the score and the strata in a United States population using the answers provided by 220 French and 148 United States adults. In the multivariable linear regression analysis, the country of origin was not a factor associated with the score (P = 0.297). The number of cNF along the different severity strata was similar between the French and the United States populations. In conclusion, stratification constitutes a powerful tool to better interpret the cNF-Skindex in daily practice and in clinical trials. This study validates its use in two populations that together constitute a large cohort of patients willing to participate in clinical research.

Neuropsychiatric Manifestations, Reduced Self-Esteem and Poor Quality of Life in Children and Adolescents with Neurofibromatosis Type 1 (NF1): The Impact of Symptom Visibility and Bullying Behavior

Neurofibromatosis type 1 (NF1) is an autosomal dominant condition, associated with neurocutaneous manifestations and neuropsychiatric manifestations. The present study explored the prevalence of bullying/cyberbullying behaviors and victimization behaviors in a cohort of children and adolescents with NF1. Possible gender differences and predictors of psychological symptoms, quality of life (QoL), and self-esteem were also examined. Thirty-eight school-aged participants with NF1 completed a psychological evaluation designed to assess anxiety and depression symptomatology, QoL, self-esteem, and the prevalence and extent of bullying/cyberbullying and victimization behaviors. We found that our participants frequently reported victimization behaviors rather than bullying/cyberbullying ones. Moreover, participants complained of depressive and anxiety symptomatology together with reduced self-esteem, and low psychosocial quality of life, with females reporting more severe performances than males. Furthermore, we found that reduced self-esteem was associated with more visibility of the NF1 symptoms, and victimization behaviors were found to mediate the relationship between anxiety and psychosocial QoL. Our findings indicated the presence of a maladaptive loop in children and adolescents with NF1 patients characterized by psychological symptoms, unfavorable self-perception, low self-esteem, and psychosocial difficulties that might be worsened by experiencing victimization behaviors. These results suggest the need to use a multidisciplinary approach in the diagnosis and treatment of NF1.

Sexual Self-Esteem and Psychological Burden of Adults With Neurofibromatosis Type 1

Neurofibromatosis type 1 (NF1) is one of the most common tumor predisposition syndromes which primarily affects the skin. NF1 is characterized by various degrees of skin tumors and pigmentation abnormalities such as café-au-lait macules. Other skin diseases, such as psoriasis or neurodermatitis, have a negative influence on sexuality and quality of life and represent a psychological burden for those affected. The present study investigated the extent to which skin tumors (disfigurement) are related to sexuality and psychosocial factors in NF1 individuals. An anonymous online survey was carried out on Facebook and the webpage of the German Neurofibromatosis Association and a total of 166 persons participated. Of these participants, 92 were affected by NF1.74 healthy persons took part in the survey as a comparative group. Results show a significant relation between sexuality, body image, quality of life and the presence of depressive symptoms of the NF1 affected persons. Individuals with NF1 show a more negative sexual self-esteem. These concerns should be taken into account in NF1- related health care approaches.

Quality of life in neurofibromatosis 1: development and validation of a tool dedicated to cutaneous neurofibromas in adults

BACKGROUND

Cutaneous neurofibromas (cNF), present in 95% of individuals with neurofibromatosis 1 (NF1), are considered as one of the greatest medical burden because of physical disfigurement. No specific score evaluates their impact on quality of life (QoL).

OBJECTIVE

To develop a specific score assessing cNF-related QoL.

METHODS

Through a multidisciplinary workshop including 10 patients, 3 expert-in-NF1 physicians, 3 health care workers (nurses and psychologist) and 1 methodologist, the French version of the Skindex-16 was modified by adding 3 items. The new cNF-Skindex was validated among patients with NF1 recruited in the ComPaRe online cohort, in France (N=284). Construct validity was assessed by comparing it with the EQ-5D-5L, its visual analog scale and the MYMOP2 and by assessing its association with patients' characteristics. Reliability was assessed by a test-retest. An English version of the tool was developed using a back forward translation.

RESULTS

A total of 228 individuals with NF1, with cNF answered the 19-item questionnaire. These items fitted into 3 domains: emotions, symptoms, functioning. One was dropped during analysis because >90% responders were not concerned. The cNF-Skindex significantly correlated with the EQ-5D-5L (N=193) and MYMOP2 (N=210) indicating good external validity: rs 0.38 (p<0.001), and 0.58 (p<0.001) respectively. Having >50 cNF was the only independent variable associated with the total score cNF-Skindex (β=15.88, 95%CI 6.96 - 24.81, p=0.001), and with the 3 sub-scores: "functioning" (β=2.65, 95%CI 0.71 - 4.59, p=0.008), "emotions" (β=17.03, 95%CI 4.11 - 29.96, p=0.010) and "symptoms" (β=3.90, 95%CI 1.95 - 5.85, p<0.001). Test-retest reliability (N=133) found an ICC at 0.96 demonstrating good reproducibility.

CONCLUSION

The cNF-Skindex demonstrated excellent psychometric properties. The global and sub-scores were increased with higher number of cNF arguing for its use in further trials aiming to reduce their number or prevent their development. Cross-cultural validation and evaluation of its responsiveness are the next steps.

Assessing Psychiatric Comorbidity and Pharmacologic Treatment Patterns Among Patients With Neurofibromatosis Type 1

Background and objective

Neurofibromatosis 1 (NF1) is a genetic disorder that is accompanied by psychiatric comorbidities such as depression, anxiety, and attention-deficit hyperactivity disorder (ADHD) in more than half of the patients. However, there are limited data describing optimal treatment strategies for these conditions. This study aimed to address that gap in understanding and explore the neurobiological basis of psychiatric comorbidities in NF1.

Materials and methods

A retrospective cohort study was conducted among NF1 patients with a comorbid diagnosis of depression, anxiety, and/or ADHD. These disease states were chosen based on their relatively high reported prevalence in NF1 and shared pathophysiological mechanisms via monoaminergic dysfunction. Information regarding demographics, psychotherapeutic medication use, and clinical outcomes was gathered from electronic medical records. Relationships between patient- and medication-related factors and outcome measures were assessed using statistical analysis.

Results

The study population (n = 82) consisted of NF1 patients with a comorbid diagnosis of depression (76.8%), anxiety (53.7%), and/or ADHD (23.2%). The use of second-generation antipsychotic agent augmentation therapy or hydroxyzine monotherapy was associated with significantly more behavioral health (BH)-related emergency department (ED) visits, admissions, and inpatient days in the study population. Conversely, the use of bupropion augmentation therapy, buspirone augmentation therapy, and stimulants was associated with improved clinical outcomes, though these results were not statistically significant.

Conclusions

Based on our findings in this real-world study setting, patients with NF1 and psychiatric comorbidities appear to experience significant benefits from medications that enhance dopaminergic neurotransmission (e.g., bupropion, stimulants) when compared to drugs that oppose it (e.g., second-generation antipsychotics).

Metalloproteinase 1 downregulation in neurofibromatosis 1: Therapeutic potential of antimalarial hydroxychloroquine and chloroquine

Neurofibromatosis type 1 is an autosomal dominant genetic disorder caused by mutation in the neurofibromin 1 (NF1) gene. Its hallmarks are cutaneous findings including neurofibromas, benign peripheral nerve sheath tumors. We analyzed the collagen and matrix metalloproteinase 1 (MMP1) expression in Neurofibromatosis 1 cutaneous neurofibroma and found excessive expression of collagen and reduced expression of MMP1. To identify new therapeutic drugs for neurofibroma, we analyzed phosphorylation of components of the Ras pathway, which underlies NF1 regulation, and applied treatments to block this pathway (PD184352, U0126, and rapamycin) and lysosomal processes (chloroquine (CQ), hydroxychloroquine (HCQ), and bafilomycin A (BafA)) in cultured Neurofibromatosis 1 fibroblasts. We found that downregulation of the MMP1 protein was a key abnormal feature in the neurofibromatosis 1 fibroblasts and that the decreased MMP1 was restored by the lysosomal blockers CQ and HCQ, but not by the blockers of the Ras pathway. Moreover, the MMP1-upregulating activity of those lysosomal blockers was dependent on aryl hydrocarbon receptor (AHR) activation and ERK phosphorylation. Our findings suggest that lysosomal blockers are potential candidates for the treatment of Neurofibromatosis 1 neurofibroma.

The Relevance of Assessing Subjective Experiences of Skin Toxicity During Adjuvant Radiotherapy for Breast Cancer

Purpose

Radiodermatitis is likely to be an inevitable side effect of radiotherapy (RT) but experiencing pain relief during RT might contribute making treatment more acceptable and less impairing. The current study aimed to assess the subjective perceptions and experiences of skin toxicity in a sample of women undergoing adjuvant RT for breast cancer.

Methods

Eighty patients were randomly assigned to one out of two groups: treatment (i.e., a newly developed topical product) and control (i.e., standard-of-care). Patients underwent adjuvant RT for 3 weeks. Clinical assessment of radiodermatitis and self-reported levels of pain, relief, and perceptions of treatment response were collected at the initiation of RT (T1), during RT (T2 and T3), and 2 weeks after treatment completion (T4). To assess changes in skin-related QoL, a subgroup of patients completed the Padua Skin-Related QoL questionnaire at T0 (before the initiation of RT) and at T4.

Results

A comparable timing of onset and severity of radiodermatitis during treatment was observed in both groups. The treatment group reported lower levels of pain and higher levels of relief compared to the control group when skin toxicity was at its highest levels (T2 and T3). Independent of the group, levels of perceived improvements in clinical status increased over time, whereas skin-related QoL worsened from T0 to T4.

Conclusion

Current findings outline the relevance of integrating clinical evaluations of radiodermatitis with patients’ subjective experiences of skin toxicity in interventional studies. Moreover, they provide preliminary evidence about the soothing effect of a newly developed topical product, thus supporting its usefulness of as a supportive care.
