Reliability of skin involvement measures in scleroderma. The UK Scleroderma Study Group.

Two methods have been proposed to quantify the extent of skin involvement in scleroderma. These are (1) a scoring system which quantifies and summates this severity rating in 17 areas of skin surface and (2) a method estimating the percentage of skin involvement using a shaded manikin. We report on a study comparing the inter-observer reliability of these two approaches using the ratings of six clinicians on 12 patients. Systematic bias between observers was noted with both methods, but inter-observer agreement, as-assessed by the intraclass correlation coefficient (ICC), was higher with the score method. The manikin method resulted in a greater degree of disagreement between the observers, as well as a higher amount of random error, reflecting the difficulty of defining the bounds of abnormal skin. Despite the presence of bias, the score method is the preferred method for assessing the level of skin involvement.

Recurrent cerebral infarction and the antiphospholipid syndrome: effect of intravenous gammaglobulin in a patient with systemic lupus erythematosus.

A 23 year old woman with systemic lupus erythematosus and antiphospholipid syndrome developed severe thrombocytopenia (5-10 X 10(9)/l) and cerebral infarction. Treatment with high doses of corticosteroids and cytostatic drugs was not effective. The condition was successfully treated only when three courses of intravenous gammaglobulin at 400 mg/kg daily was added. A clear relation was found between the immunoglobulin infusions and rising platelet counts, whereas an effect on the levels of anticardiolipin antibodies could not be recorded. The findings suggested that the mechanisms responsible may be modification and solubilisation of immune complexes or interference with anticardiolipin binding to platelet membranes, or both.

[Favourable surgery of cervical neck instability in rheumatism].

A team project commenced 20 years ago can now present results of 150 surgical stabilising procedures for cervical neck instability in rheumatoid arthritis. The favourable results indicate widened indications. MR examination demonstrated regression of soft tissue swelling ("pannus") after surgery, which possibly contributed to the good results.

Detection of suspected inflammatory joint disease with a new simple self-administered hand test.

A self-administered hand test was used to screen 5262 persons aged 40-70 living in a rural district in southern Sweden. It revealed evidence of hand impairment in 13%. The prevalence of RA was 1.1%. At the screening procedure a subgroup of 48 previously unrecognized individuals with inflammatory joint disease was identified. They were assessed by a rheumatologist, who established the following diagnoses: four definite RA, eight probable RA, three psoriatic arthritis, one unclassifiable arthritis, 10 osteoarthritis and 22 non-specific arthralgia. No advanced RA was detected. Two were seropositive and another was erosive. One with RA, one with psoriatic arthritis and three with arthralgic symptoms were unable to work. Most had only a minor need for further medical aid. The test was thus able to identify persons with hand impairment. Follow-up studies will address the practical implications of the screening procedure.

Reduction of rheumatoid periodontoid pannus following posterior occipito-cervical fusion visualised by magnetic resonance imaging.

Nine patients (four females and five males) with chronic rheumatoid arthritis (RA) and atlanto-axial (AA) instability subjected to occipito-cervical fusion were evaluated clinically and radiologically. All of them had soft tissue formation (pannus) around the odontoid peg. The age ranged from 50 to 79 years (mean: 66). The duration of the RA disease was 3-48 years (mean: 18.5). All patients were seropositive. Both conventional radiography and magnetic resonance imaging (MR) were performed pre- and postoperatively. All fusions except one were stable. One patient was re-fused after 2 months because of wire break. With regard to pain all patients had improved and eight were pain free. Six patients who experienced signs of myelopathy prior to the fusion had improved at follow up. MR revealed reduction of pannus in all nine cases. This was obvious in one patient within 6 weeks postoperatively. The MR findings of a reduction or even disappearance of pannus following posterior fusion should decrease the need for transoral surgery.

Esophageal dysfunction and radionuclide transit in progressive systemic sclerosis.

Sixty patients with progressive systemic sclerosis (PSS) were studied by radionuclide esophageal transit (RT) and esophageal cineradiography. Fifty-two patients (87%) had abnormal RT with prolonged transit time and 28 (47%) had stagnation of radionuclide. RT was positively correlated to duration of disease (p less than 0.01). A positive correlation between transit time and the presence of dysphagia was observed. Reduced esophageal motility evaluated by cineradiography was observed in 44 patients (73%). In patients with moderate-severe esophageal dysfunction there was a positive association between prolonged RT and hypomotility at the radiological examination (p = 0.001). RT is a safe and non-invasive method which is more sensitive than cineradiography and might be used as a screening test to evaluate esophageal involvement in patients with PSS.

Gastrointestinal function in patients with progressive systemic sclerosis.

In 24 patients with progressive systemic sclerosis (PSS) the pentagastrin-stimulated gastric acid secretion was determined to investigate if acid hypersecretion is associated with reflux-oesophagitis--the most common complication to oesophageal involvement in PSS. Gastro-oesophageal reflux was observed in 12, reflux-oesophagitis in 9 and oesophageal mycosis in 8 patients. Gastric acid secretion was increased in 13 (54%) patients and tended to be higher in patients with oesophagitis. Patients with reflux and increased acid secretion seemed to be free from oesophageal mycosis. Bacterial overgrowth and malabsorption are known complications to intestinal scleroderma and these items were investigated using non-invasive methods. Four patients had increased bile acid deconjugation, 3 had increased (14C)xylose degradation indicating bacterial overgrowth and 7 patients had decreased fat absorption in the triolein breath test. Nutritional status with respect to selenium, folate, cobalamin and fat-soluble vitamins was essentially normal.

Systemic lupus erythematosus in an adult population in southern Sweden: incidence, prevalence and validity of ARA revised classification criteria.

In a defined Swedish population an annual incidence of 4.8 cases, a mortality of 1.3 cases and a prevalence of 39 cases per 100 000 individuals was found for systemic lupus erythematosus. Sensitivities were comparable (94%, cf. 92%) for ARA criteria of 1982 and those of 1971. Males had more internal organ criteria and showed a tendency to fewer cutaneous criteria than females. Spontaneous abortion was rare and hospitalization infrequent among the 65 patients studied.

Systemic lupus erythematosus and infection: a controlled and prospective study including an epidemiological group.

An epidemiological group of 60 SLE patients was studied; 162 infections were observed prospectively for an aggregate of 1366 months. Bacterial infection was more frequent in the SLE patients than in matched controls but only slightly more frequent than in matched rheumatoid arthritis patients. The rheumatoid arthritis patients, also matched with regard to corticosteroid dosage, showed a tendency towards an increased infection rate only. Lower urinary tract infections were comparable in all three matched groups. In a total of 102 SLE patients studied, including the epidemiological group, clinical SLE activity was accompanied by an increase in the frequency of bacterial infection. In 49 patients bacterial infections were more common after flare than before. There was a high incidence of mucocutaneous infections induced by S. aureus, where skin traumatisation was an added risk factor. No increase of opportunistic infections was found in matched groups, but 26 such infections occurred in the subjects as a whole, and they were seen to be more frequent in conjunction with steroid-treated active SLE. Admission to hospital because of suspected infection was common, and infection was the cause or a contributory factor in five of the seven deaths among SLE patients.

Ultrasound examination of skin thickness in patients with progressive systemic sclerosis (scleroderma).

A new ultrasound technique for measuring skin thickness in 40 patients with progressive systemic sclerosis (scleroderma) and in 10 healthy control subjects has been evaluated. High frequency (10 MHz) dynamic ultrasound examination was performed at the proximal and middle phalanges of both second fingers. Measurements of the control subjects on two separate occasions demonstrated a good reproducibility of the technique with a standard deviation of 0.06 mm. The skin was thicker in patients with scleroderma 3.3 +/- 0.7 mm (mean +/- SD) compared with control subjects 2.5 +/- 0.2 mm (p less than 0.001). No relation between skin thickness and duration of disease was observed. This method can be used to monitor changes in skin thickness over time.

Serum aminoterminal type III procollagen peptide in early rheumatoid arthritis: relation to disease activity and progression of joint damage.

Serum levels of the aminoterminal type III procollagen peptide (S-PIIINP) have been used as markers of proliferative inflammation in rheumatoid arthritis (RA) and a prognostic significance has been suggested. To test this further we have measured S-PIIINP longitudinally for 2 years in 66 patients with definite RA and a disease duration of less than 2 years, and related the levels to clinical, biochemical, and radiographic findings. In this patient group the correlations between S-PIIINP and ESR and CRP, respectively, were higher than those obtained between S-PIIINP and articular indices, and markedly higher than in patients with RA of longer duration. Patients with normal mean levels of S-PIIINP during the study period had a significantly slower rate of radiographic progression than patients with elevated mean levels of S-PIIINP. ESR yielded in general higher correlations with the joint damage process than did S-PIIINP. The correlations between S-PIIINP and the joint damage scores increased with time. A multiple regression analysis showed that ESR explained most of the variance in joint damage progression over 2 years, but S-PIIINP added independent information. About one third of the variance could be explained by the two variables.

Inhibition of in vivo leucocyte migration by NSAIDs.

Leucocyte migration was studied in vivo using a skin window technique, and in vitro by migration under agarose. No difference was found between 28 patients with rheumatoid arthritis (RA), 10 patients with psoriatic arthritis (PA) and 30 healthy controls. Most patients were under treatment with anti-rheumatic drugs. Patients treated with non-steroidal anti-inflammatory drugs (NSAIDs) had significantly lower values (p less than 0.01) than untreated patients. In vivo but not in vitro migration decreased during short-term treatment with diclofenac and naproxen, an effect observed both in patients and in healthy individuals. After pre-incubation of normal polymorphonuclear leucocytes with diclofenac, in vitro migration was diminished only at concentrations of 50 micrograms/ml and above, which are at least 10 times higher than those attained clinically. The in vivo effect of NSAIDs on leucocyte migration may imply a long-term disease modifying influence in chronic arthritides.
