Neuropaattinen käsikipu nivelreumassa
Reumatoidisen käsikivun neuropaattiset ominaisuudet ja sen suhde aistinvaraisiin kynnyksiin ja unen laatuun: tapauskontrollitutkimus
Investigators have aimed to estimate prevalence of neuropathic hand pain in RA patients and it's relation with sleep quality and sensory thresholds. For this purpose a case-control study design was planned. Age- and sex-matched control subjects will be chosen among individuals submitted to out-patient clinic with the complaint of nociceptive/mechanical pain other than in hand, lasting more than three months

Yksityiskohtainen kuvaus
Rheumatoid arthritis (RA) is a chronic, inflammatory rheumatic disease that predominantly affecting peripheral joints. Patients with RA are suffered from severe hand pain and functional loss because of synovitis in hand joints. The fact that patients with low disease activity may complain from hand pain suggests that pain is mediated by mechanisms other than inflammation. Contribution of central sensitization to pain sensation of RA patients is of interest currently. Several authors reported the neuropathic characteristics of hand pain in RA. Hand pain is primarily nociceptive in RA patients but the possibility of variances in cutaneous sensitivity due to nociceptive input from joints has been suggested. Increased sensitivity with light touch has been demonstrated over hands of RA patients. In RA patients, alterations in central processing of somatosensory function and allodynia over inflamed joints have been reported. Poor sleep quality is another issue for RA patients and it's association with pain was reported. However impact of neuropathic hand pain on sleep quality was not understood exactly probably due to the scarce of the studies investigating this association. Also, to the best of investigators' knowledge, the relation between neuropathic component of pain and sensory threshold alterations in rheumatoid hand was not studied to date.
So, investigators have aimed to estimate prevalence of neuropathic hand pain in RA patients and it's relation with sleep quality and sensory thresholds. For this purpose a case-control study design was planned. Age- and sex-matched control subjects will be chosen among individuals submitted to out-patient clinic with nociceptive/mechanical pain complaint other than in hand lasting more than three months. Also whether sensory thresholds in rheumatoid hands differ from healthy hands will be assessed. Participants in control group will be subjected to same exclusion criteria too.
This design will allow the investigators to determine whether hand pain in RA patients displays neuropathic character more frequently than any other chronic nociceptive pain does. Moreover, it will be possible to compare sensory thresholds between healthy and rheumatoid hand. RA patients diagnosed according to the 1987 American College of Rheumatology criteria will be recruited. Demographics and disease related variables will be recorded.

Neuropathic pain
Aikaikkuna: Once, at baseline
|
It will be assessed using the painDETECT questionnaire. This questionnaire, contains nine questions all of which are selfreport. Seven items are rated on a six point Likert scale and thus are scored between 0-5. These seven questions query some sensations such as burning, tingling or prickling, allodynia, numbness etc. Apart from these seven items, one item assesses the radiation of pain and the other one item looks for the temporal characteristics of pain. A total score of 12 or less indicates neuropathic component is unlikely, 13-18 means possible neuropathic component and19 or greater means a neuropathic component is likely. Beside these, there are three items in a separate section measuring severity of pain at the time of evaluation, on average and maximum over the past month. This section is not taken into account in scoring |
Once, at baseline
|
|
Sleep quality
Aikaikkuna: Once, at baseline
|
It will be assessed using Pittsburgh Sleep Quality Index (PSQI). It was developed by Buysse and coworkers in 1989. This index measures sleep quality quantitatively and covers 24 questions. Nineteen questions are self-rated and scoring is based on these self-rated questions, other five questions that rating by partner are not taken into account while calculating total score. Questionnaire measures seven domains; subjective sleep quality (question 6), sleep latency (question 2 and 5a), sleep duration (question 4), habitual sleep efficiency (question 1,3,4), sleep disturbances (question 5b-j), use of sleep medication (question 7), and daytime dysfunction (question 8 and 9) over the last month. Seven domain scores give a result on a 0 to 3 scale. To yield a total score the domain scores are summed. Total score varies between 0 and 21. Higher scores indicate worse sleep quality. |

Light touch-pressure threshold
Aikaikkuna: Once, at baseline
|
It will be assessed using Semmes-Weinstein monofilament test composing of five filaments ranging in thickness from 2.83 to 6.65 mm and applying force ranging from 0.07 g to 300 g. The procedure is started by getting the thinnest filament in contact to relevant skin region. If it is not felt after three trials with same filament, examiner proceeds with the next more larger filament until touch felt by the patient. |

Depression
Aikaikkuna: Once, at baseline
|
It will be assessed using Beck Depression Inventory. It is is a 21-question multiple-choice self-report inventory quantifies the symptoms of depression. Each question is rated between 0 and 3 to reflect the intensity of statements. All points are summed arithmetically to obtain a total score which ranges between 0 and 63. Higher scores indicate more intense depressive symptoms. |
