Patients’ recollection about the onset of Sjögren’s disease – a mixed methods study on the patients’ perspective

Abstract

Abstract Background Little is known about the symptoms at the onset of Sjögren’s Disease (SjD) and it is unclear whether SjD starts with characteristic symptoms that could be differentiated from dryness of other origin (sicca syndrome). The aim of this study was to investigate patients’ recollection of initial events and first symptoms of SjD. The second aim was to verify and quantify these aspects in a representative cohort. Methods All SjD patients fulfilled the EULAR/ACR 2016 classification criteria. In the first part of the study, consecutive SjD patients were recruited for individual, semi-structured interviews. All interviews were audio-recorded and transcribed verbatim, and an inductive thematic data analysis was performed. In the second part, the identified aspects of the qualitative analysis were grouped into a checklist with ten items. Results One-hundred and thirty-four patients participated in the study. 31 SjD patients completed the qualitative part. Major aspects emerged of how patients experienced the beginning and first symptoms of SjD: (1) “classic” SjD symptoms (fatigue, pain, dryness) (2), sicca symptoms started after initial swelling of parotid and/or lymph nodes (3), after hormonal transition or infections before the onset of SjD symptoms. In the second part of the study, the previous identified major aspects were verified in an independent cohort of 103 SjD patients. The main symptom before diagnosis was dryness (n = 77, 74.8%) with migratory joint pain (n = 51, 49.5%) and fatigue (n = 47, 45.6%). In 38.8% (n = 40), patients reported a swelling/inflammation of the parotid gland at the onset of disease. Conclusions We describe patients’ recollection of the onset of SjD. Raising awareness of the symptoms identified among physicians and among the general public may allow earlier diagnosis of SjD.
