Potential limitations of activity tracking devices in monitoring effects of treatment for sarcoidosis.

INTRODUCTION:   activity tracker device usage can help analyze the impact of disease state and therapy on patients in clinical practice.  factors such as age, race, and gender may contribute to difficulties with using such technology.  Objective: we evaluated the effect of age, race, and gender on the usability of the Fitbit OneTM activity tracking device in sarcoidosis patients and the impact of device on sarcoidosis patients' activity. METHOD: patients participated in a six-month prospective study where were asked to wear a Fitbit OneTM activity tracker daily. device usage education was provided at study enrollment.  weekly data download and submission reports to participating centers was required. patients were asked to complete a post-study questionnaire reviewing the motivation of the activity tracker on daily activity. RESULTS: at three centers, 91 patients completed all study visits and the post study questionnaire with a mean age of 55 and 75% were female and 34% african american. accurate downloads occurred >75% of the time, regardless of age, race, or sex. results of the post-study questionnaire did not show a correlation between the likelihood of wearing the device and motivation to increase activity. CONCLUSION: using an activity tracking device to evaluate and/or correlated with quality of life (QOL) instruments may prove beneficial for gathering more data on patients.  age, race, and gender did not contribute to differences in usability among sarcoidosis patients.

ERS clinical practice guidelines on treatment of sarcoidosis.

BACKGROUND: The major reasons to treat sarcoidosis are to lower the morbidity and mortality risk or to improve quality of life (QoL). The indication for treatment varies depending on which manifestation is the cause of symptoms: lungs, heart, brain, skin or other manifestations. While glucocorticoids remain the first choice for initial treatment of symptomatic disease, prolonged use is associated with significant toxicity. Glucocorticoid-sparing alternatives are available. The presented treatment guidelines aim to provide guidance to physicians treating the very heterogenous sarcoidosis manifestations. METHODS: A European Respiratory Society Task Force committee composed of clinicians, methodologists and patients with experience in sarcoidosis developed recommendations based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) methodology. The committee developed eight PICO (Patients, Intervention, Comparison, Outcomes) questions and these were used to make specific evidence-based recommendations. RESULTS: The Task Force committee delivered 12 recommendations for seven PICOs. These included treatment of pulmonary, cutaneous, cardiac and neurologic disease as well as fatigue. One PICO question regarding small-fibre neuropathy had insufficient evidence to support a recommendation. In addition to the recommendations, the committee provided information on how they use alternative treatments, when there was insufficient evidence to support a recommendation. CONCLUSIONS: There are many treatments available to treat sarcoidosis. Given the diverse nature of the disease, treatment decisions require an assessment of organ involvement, risk for significant morbidity, and impact on QoL of the disease and treatment.

Sarcoidosis: patient treatment priorities.

Sarcoidosis patient survey reveals QoL and functionality are required as core outcomes in treatment and care, along with more multidisciplinary working by clinicians and the establishment of specialist sarcoidosis centres in every European country http://ow.ly/DTvt30mQnqc.

New advances in the development of sarcoidosis models: a synopsis of a symposium sponsored by the Foundation for Sarcoidosis Research.

Sarcoidosis is a complex disease with variable phenotypes that will require a multisystem approach to understand pathophysiology. One of the most challenging problems in sarcoidosis research is the absence of valid and widely accepted experimental models that accurately simulate human disease. The Foundation of Sarcoidosis Research (FSR) has funded five projects for the development of novel experimental models for sarcoidosis, presented and discussed in a workshop organized during the European Respiratory Society Congress held in Milan from September 9th to 13th. The experimental, in vivo or in sillico models presented may be quite helpful for investigating specific pathogenic and therapeutic questions, addressing especially severe forms of sarcoidosis.
