To the editor

Scleroderma is a disease characterized by functional and structural abnormalities in blood vessels and fibrous involvement of skin and internal organs.1 Although the treatment effort is directed mostly against visceral lesions that can diminish life expectancy, scleroderma patients may also experience difficulties with less serious organ damage. Scleroderma patients may present hand dysfunctions that cause difficulties in performing daily activities. Hand dysfunction in scleroderma cases may be caused by RP (Raynaud phenomenon) with finger ulcers,1 arthralgia, arthritis, tendonitis,1 weakness2 and skin thickening, which cause loss of dexterity.1,2 Nacci et al.1 observed that the most limiting determinant was joint involvement. Others3 observed that rigidity, RP and weakness were the major contributors.

We studied hand dysfunction in 46 patients with scleroderma (four males and 42 females; mean age of 50.5 years; mean disease duration of 7.4 years). Twenty-nine presented the limited form, 11 presented the diffuse form and six cases overlapped with other connective tissue diseases. In this sample, 28.2% were employed workers; 10.8% were homemakers; 36.9% had retired due to health problems; and 15.2% had retired because of age. The patients were asked about the presence of hand symptoms and answered the Dreiser index questionnaire.4 This questionnaire contains 11 questions about activities of daily living. It is measured through a Likert scale (0 = no difficulty; 1 = slight difficulty; 2 = moderate difficulty; 3 = impossible to perform) and ranges from 0 (no dysfunction) to 33 (maximum dysfunction). It was initially created to evaluate hand osteoarthritis but has also been used in scleroderma cases.1 Patients with pain and stiffness were asked to grade their symptoms through a visual analogue scale (VAS) on which 0 corresponded to no symptoms and 10 to the maximum symptoms.

We found the following: RP in 93.5%; arthritis (present or previous) in 73.9%; hand stiffness in 73.9%; pain in the hand (overall) in 71.73%; arthralgia in 65.2%; skin ulcerations (present or previous) in 58.6%; and calcinosis in 26.6%. The Dreiser index results ranged from 0 to 25 (mean: 8.69 ± 8.02). The association between the Dreiser index and hand symptoms is shown in Table 1.

 

 

The mean VAS obtained for pain in the hand was 7.12 ± 2.26 and for stiffness, it was 6.17 ± 2.05. There were positive correlations between the Dreiser index values and the VAS for pain (r = 0.47; P = 0.006) and between the index and the VAS for stiffness (r = 0.69; P < 0.0001).

Hand dysfunction is not always taken into account in scleroderma cases, but Roberts-Thomson et al.5 showed that it can be as incapacitating as in rheumatoid arthritis.

We found that pain and stiffness were the symptoms that most affected functionality. Every effort should be directed towards treating these symptoms, in order to improve scleroderma patients' wellbeing.
