Common Causes of Pain in Systemic Sclerosis: Frequency, Severity, and Relationship to Disease Status, Depression, and Quality of Life.

BACKGROUND: In routine clinical practice, healthcare professionals draw little attention to pain in patients with systemic sclerosis (SSc). Pain has adverse effects on functional ability, social and emotional wellbeing. AIMS: This study aims to assess the frequency and severity of different types of pain in patients with SSc, and the relationship of pain with disease status, depression and quality of life. DESIGN: Consecutive patients with SSc were included in this cross-sectional study. Patients with previously diagnosed painful diseases or conditions (other rheumatic diseases, angina pectoris, neurological disorders, etc.) were excluded. SETTINGS: Patients, who visited our rheumatology outpatient clinic from February to November 2016, participated in this study. PARTICIPANTS/SUBJECTS: 42 consecutive patients with SSc (38 women and 4 men), mean age 56.5 years, mean disease duration 9.5 years, were included. METHODS: All patients filled in a questionnaire, to indicate the presence or absence of some predefined pain syndromes. Disease status was assessed using the Scleroderma Assessment Questionnaire (SAQ), symptoms of depression by the Beck's Depression Inventory (BDI), whilst the quality of life was evaluated using the EuroQol questionnaire. RESULTS: It was found that 92.9% of SSc patients suffer from different types of pain, and 45.2% of patients have pain every day. Joint pain was the most common type of pain, present in 78.6% of patients, followed by pain associated with Raynaud's phenomenon (69%), back pain (47.6%), headache (31%), chest pain (23.8%), odynophagia (21.4%) and painful digital ulcers (19%). Symptoms of neuropathic pain were noticed in 26.2% of patients. Severe joint pain, everyday pain and symptoms of neuropathic pain in SSc were associated with more severe disease and poorer quality of life. Pain related to Raynaud's phenomenon, digital ulcers, odynophagia and joint pain were associated with significant symptoms of depression. CONCLUSION: The majority of patients with SSc suffer from different types of pain. Pain is associated with more severe disease, depression and poor quality of life.

The Serbian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR).

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient-reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Serbian language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the three Likert assumptions, floor/ceiling effects, internal consistency, Cronbach's alpha, interscale correlations, test-retest reliability, and construct validity (convergent and discriminant validity). A total of 248 JIA patients (5.2% systemic, 44.3% oligoarticular, 23.8% RF-negative polyarthritis, 26.7% other categories) and 100 healthy children were enrolled in three centres. The JAMAR components discriminated healthy subjects from JIA patients. All JAMAR components revealed good psychometric performances. In conclusion, the Serbian version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practice and clinical research.

Neurological and electroneurography findings in patients with systemic sclerosis and symptoms of neuropathic pain in extremities.

OBJECTIVE: To analyze neurological and electroneurography (ENG) findings in patients with systemic sclerosis (SSc) and symptoms of neuropathic pain in upper and lower extremities. PATIENTS AND METHODS: Using the PainDetect questionnaire, 42 consecutive patients with SSc (38 women and 4 men) were screened for the presence of neuropathic pain in upper and/or lower extremities. Patients with previously diagnosed diabetes or other metabolic diseases, malignancy, other autoimmune disorders, or any neurological or psychiatric disease, were not included. Neurological examination, ENG, and laboratory analyses (glycated hemoglobin-HbA1C, and vitamin B12) were performed in SSc patients with neuropathic pain in extremities. Methods of descriptive statistics were used to summarize the data. RESULTS: Eleven patients (26.2%) had significant symptoms of neuropathic pain in extremities. Neurological examination indicated polyneuropathy in 10/11 (90.9%) of patients. Symmetrical hyperesthesia in the lower and/or upper extremities was found in ten patients. Symmetrical hyporeflexia was found in 7/11 (63.6%) of patients in the arms, and 6/11 (54.4%) of patients in the legs. Proprioception was diminished in 3/11 (27.3%), whilst pallhypesthesia was present in all patients. However, polyneuropathy could be confirmed by ENG only in four out of ten SSc patients, who had typical neurological findings for polyneuropathy. Hypoesthesia in a specific lumbar root dermatome, suggesting radiculopathy, was found in 6/11 (54.5%) of patients. Asymmetrical hyporeflexia was noticed in 2/11 (18.1%) of patients in the lower limbs. Seven patients (63.6%) had signs of radiculopathy in at least one root dermatome on ENG. CONCLUSION: A significant number of SSc patients with neuropathic pain in the upper and/or lower extremities have symptoms and signs of polyneuropathy undetectable by ENG, which indirectly suggests the presence of small-fiber polyneuropathy in these patients. In some patients, radiculopathy cannot be excluded as possible co-morbid non-scleroderma condition associated with neuropathic pain.

[Ability of the Childhood Health Assessment Questionnaire in predicting outcome of patients with juvenile idiopathic arthritis].

INTRODUCTION: Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease associated with decreased functional capacity and potentially long-term consequences. The establishment of early prognostic factors could help in the prevention of joint damage and improve the quality of life in children with JIA. OBJECTIVE: The aim of the study was to evaluate the functional status of children with JIA by using the Childhood Health Assessment Questionnaire (CHAQ) and to assess its ability in predicting the outcome of the disease. METHODS: The study included 87 patients, average age 14 years, under follow-up on the average of 3.7 years. Parents/ patients over 12 years completed CHAQ based on which disability index (DI) was calculated. Disease outcome was determined according to the preliminary criteria for clinical remission. RESULTS: At the end of the follow-up period, functional ability improved significantly (0.541 vs. 0.398; p<0.05). During the study, in 52.8% of patients treatment with biologic drug etanercept was introduced. CHAQ showed good predictive validity when a baseline DI was compared with disease outcome at the final examination (F=18.349; p<0.001). Using the patients with normal functional ability (DI=0) as the reference group, in patients with moderate and more severe functional disability the odds ratio for the disease to be active at the end of the follow-up period (DI> or =0.6) was 4.6 (p=0.044). CONCLUSION: Functional ability of patients with JIA significantly improved during the follow-up period owing to the efficient therapy. The questionnaire for the assessment of the functional status is a simple tool, with good ability to predict disease outcome, and should thus be used in everyday clinical practice with the aim to identify patients with poor prognosis.
