Gastrointestinal accumulation of indium-111 labelled granulocytes in reactive arthritis.

Six patients with reactive arthritis (ReA) were examined for gastrointestinal accumulation of Indium-111 labelled granulocytes. Abnormal scintigrams were found in three of six patients all of which showed early (less than 4 h) accumulation of indium-111 labelled granulocytes which may represent small intestinal inflammation. Our findings may indicate that the small intestine is involved in ReA, and that indium-111 granulocyte scintigraphy is a useful method for demonstrating inflammatory changes in the small intestine in reactive arthritis (ReA).

The effects of dietary supplementation with n-3 polyunsaturated fatty acids in patients with rheumatoid arthritis: a randomized, double blind trial.

STUDY OBJECTIVE: To determine the effect of dietary supplementation with n-3 polyunsaturated fatty acids (n-3 PUFA) on disease variables in patients with rheumatoid arthritis. DESIGN: Multicenter, randomized, placebo controlled, double blind. SETTING: Three Danish hospital Departments of Rheumatology. PATIENTS: Fifty-one patients with active rheumatoid arthritis. INTERVENTION: Random allocation to 12 weeks of treatment with either six n-3 PUFA capsules (3.6 g) or six capsules with fat composition as the average Danish diet. MAIN RESULTS: Significant improvement of morning stiffness and joint tenderness. No significant effect on the four other assessed clinical parameters. No serious side effects. CONCLUSIONS: Dietary supplementation with n-3 PUFA in patients with rheumatoid arthritis improved two out of six patient reported disease parameters. Further studies are needed to clarify the more precise role of n-3 PUFA in the treatment of rheumatoid arthritis.

Toxoplasma pericarditis mimicking systemic lupus erythematosus. Diagnostic and treatment difficulties in one patient.

A life-threatening T. gondii pericarditis developed in a patient with symptoms corresponding to systemic lupus erythematosus (SLE) with high concentrations of antinuclear antibodies and lymphadenopathy. The diagnosis would have been SLE-associated serositis, had not pericardial fluid been inoculated into mice, because pericarditis is frequently seen in SLE and false positive toxoplasma seroreactions may occur in ANA positive patients. High IgG T. gondii antibodies without increased IgM antibodies indicated reactivation rather than primary infection. Prolonged high-dose treatment with pyrimethamine-sulphadiazine was needed. Interestingly, the patient's SLE symptoms, including high ANA antibodies, declined to an unexpected remission after treatment for toxoplasmosis. This may not be mere coincidence, but may point to a causative role of toxoplasmosis in some cases of SLE.

[Naproxen versus indomethacin as night-time medication for patients with rheumatoid arthritis].

The investigation consisted of a double-blind cross-over study of the effect of 75 mg indometacin, 500 mg naproxen or a placebo in 63 patients with rheumatoid arthritis accompanied by night pain and morning stiffness. All the patients received day treatment with 250 mg naproxen b.i.d. Only a few patients benefitted from the treatment at night and no differences in the effect of indometacin and naproxen were observed. Naproxen was better tolerated than indometacin. Day treatment with naproxen, which has a relatively long half life time decrease the need for supplementary treatment at night.

Double blind placebo controlled trial of pulse treatment with methylprednisolone combined with disease modifying drugs in rheumatoid arthritis.

OBJECTIVE: To assess whether monthly treatment with intravenous methylprednisolone enhances or accelerates the effect of disease modifying drugs in patients with rheumatoid arthritis. DESIGN: A 12 month double blind, placebo controlled, multicentre trial in which patients with active rheumatoid arthritis were randomly allocated to receive pulses of either methylprednisolone or saline every four weeks for six months. At the start of the pulse treatment all patients were started on penicillamine or azathioprine. SETTING: Four rheumatology departments in Denmark. PATIENTS: 97 Patients (71 women, 26 men) aged 23-84 (mean 60) who had active rheumatoid arthritis of at least four weeks' duration despite treatment with non-steroidal anti-inflammatory drugs. MAIN OUTCOME MEASURES: Monthly clinical recording of morning stiffness, number of tender and swollen joints, blinded observers' evaluation of therapeutic effect, and patients' self assessed condition. Concomitant laboratory measurements of erythrocyte sedimentation rate and concentrations of C reactive protein and haemoglobin. Radiography to determine the number of erosions at the start of treatment and after 12 months. RESULTS: 57 Patients completed the trial, taking the same disease modifying drug throughout. Evaluation four weeks after each pulse treatment and at 12 month follow up showed no significant differences between the methylprednisolone and placebo groups in any of the clinical or laboratory variables. Radiography showed the same degree of progression of erosions in both groups. Evaluation of the total data on 97 patients and on the 57 who completed the trial showed the same lack of significance between the treatment groups. CONCLUSIONS: Intravenous pulse treatment with steroids can be recommended only for rapid temporary relief of flares of disease in patients with rheumatoid arthritis. The response is short lived. Repeated pulses of methylprednisolone at four week intervals do not improve the results of treatment with drugs that induce remission such as penicillamine and azathioprine.

[The incidence of fibromyalgia in patients admitted to a rheumatology department].

One hundred patients admitted consecutively to Kong Christian X Hospital for rheumatic conditions were examined for symptoms of fibromyalgia. 47% of the patients had not only histories of pain in three or more anatomically separate regions but also presence of at least seven tender points in the soft tissues on palpation of 15 sites of predilection for tender points. This investigation suggests a high incidence of secondary fibromyalgia in patients admitted on account of various rheumatic conditions.

[Examination of tender points in soft tissue. Palpation versus pressure-algometer].

Tender points may be identified by two methods, either by palpation or employment of a pressure-algometer. The inter- and intra-observer agreements between the two methods are investigated in the present article. The investigation consists of three sections: 1. Twenty-five female patients with various rheumatic conditions were examined by two investigators for tender points at 15 sites of predilection, immediately after one another both as regards palpation/palpation and pressure-algometer/pressure-algometer. Acceptable inter-observer agreement was found on palpation with an average value employing Cohen's kappa-coefficient of 0.68 and an unacceptable inter-observer agreement with average values employing Cohen's kappa-coefficient of 0.42, 0.39 and 0.44 with pressure thresholds of under 3.0, 4.0 and 5.0 kg/cm2. 2. Twenty-five female volunteers in whom only knees were visible were examined twice immediately after one another by the same examiner by palpation on the medial fat pad of the right knee and by pressure with the pressurealgometer on the medial fat pad of the left knee. Good intra-observer agreement was found by both methods with Cohen's kappa-coefficient ranging between 0.75 and 0.83. 3. Sixty-five consecutive patients admitted to Kong Christian X Hospital for Rheumatic Diseases were examined for tender points at 15 sites of predilection by two examiners immediately after one another employing palpation/pressure-algometer. Poor agreement was found between the two methods. Employment of the pressure-algometer may be useful in research where quantitating of the threshold of pain is desired, but, in the daily clinical routine, palpatory examination for tender points is just as good or better than employment of an algometer.

Anaemia of rheumatoid arthritis: serum erythropoietin concentrations and red cell distribution width in relation to iron status.

Immunoreactive serum erythropoietin concentrations were measured in 35 patients with anaemia associated with active rheumatoid arthritis. Based on an evaluation of stainable iron in the bone marrow (marrow iron grade 0-4) and serum ferritin concentrations (concentrations less than or equal to 60 micrograms/l compatible with iron deficiency) the anaemia was found to be complicated by iron deficiency in 19/35 (54%) of the patients. The mean serum erythropoietin level (57.6 (SD) 27.3) U/l) was sufficiently raised for the degree of anaemia irrespective of the size of the marrow iron stores. Thus the data do not support the contention that suppressed secretion of erythropoietin is involved in the pathogenesis of anaemia of chronic disorders. There was a significant inverse correlation between the haemoglobin concentration and log serum erythropoietin in the patients with rheumatoid arthritis. In the patients with adequate iron stores, but not in the iron depleted patients, there was a tendency for serum erythropoietin concentrations to correlate positively both with C reactive protein and erythrocyte sedimentation rate. Red cell distribution width (mean (SD) 16.3 (1.8)%) was above normal (11.5-14.5%) both in the iron replete and the iron depleted patients, and the mean red cell distribution width values did not differ significantly among the two subpopulations. The plasma lactoferrin concentration (mean (SD) 137.6 (109.9) micrograms/l) was normal and did not differ significantly between the iron deficient patients and those with adequate iron.

Antikeratin antibodies in synovial fluid in rheumatoid arthritis.

Serum and synovial fluid of 20 patients with classical or definite rheumatoid arthritis (RA) were tested for antikeratin antibodies (AKA) by indirect immunofluorescence using rat esophagus as antigen. AKA were found in 80% of the RA patients, in serum as well as in synovial fluid. None of the 54 serum control patients were AKA positive in serum. None of the 17 synovial fluid control patients were AKA positive in synovial fluid. F(ab)'2 fragments prepared from AKA positive RA serum retained antibody activity. AKA belonged to the IgG class of immunoglobulins. Corrected for the lower IgG content in synovial fluid, AKA constituted a higher percentage of the IgG in synovial fluid than in serum. This could imply a possibility of local production of AKA in the joint.

Serum aminoterminal type III procollagen peptide in inflammatory and degenerative rheumatic disorders.

Measurement of the aminoterminal type III procollagen peptide in serum has been suggested as a marker of the biosynthesis of collagen type III, a major connective tissue component in repair processes. In the present study the propeptide level correlated with the inflammatory synovial mass in rheumatoid arthritis and osteoarthritis. This implies that the propeptide level reflects the collagen type III synthesis occurring in the synovial repair processes, whether they were caused by inflammatory or degenerative rheumatic disorders. Physical activity did not enhance the transition of the propeptide from the synovial fluid or the inflamed synovial membrane to the blood. Normal serum propeptide values were observed in most patients with ankylosing spondylitis and degenerative diseases of the spine. This may reflect the lower amount of inflammatory tissue in these diseases and hence the sensitivity of the assays.

Giant-cell arteritis. Histological, immunohistochemical and electronmicroscopic studies.

Biopsies from the temporal artery of 32 patients suspected of giant-cell arteritis were evaluated retrospectively by light microscopy, histochemical, and immunohistochemical methods, as well as by transmission electron microscopy (TEM). At the clinical follow-up the 32 patients included four clinical groups: temporal arteritis (8 patients), polymyalgia rheumatica (10 patients), rheumatoid arthritis (4 patients), and a group of miscellaneous diseases unrelated to inflammatory rheumatic diseases (10 patients). There were a number of similarities between age-related alterations in the arteries and the changes in giant-cell arteritis. The most important differences were the inflammatory cellular infiltration of the media, the perifocal accumulation of fibronectin, and the occurrence of deposits of fibrin/fibrinogen and fibrin/fibrinogen degradation products. In addition, alpha-2 macroglobulin, lysozyme and factor VIII were also noted in giant-cell arteritis. The alterations in giant-cell arteritis show a number of similarities to the changes following experimental vascular injury of the rabbit aorta. The nature of the findings in human giant-cell arteritis, as well as the similarity to the experimental arteritis, indicate that giant-cell arteritis may reflect a non-specific reaction to injury, independent of the cause of the disease.

Combination of methylprednisolone pulse therapy and remission inducing drugs in rheumatoid arthritis.

Thirty patients with rheumatoid arthritis were allocated to either methylprednisolone pulse therapy or placebo at the beginning of treatment with either gold salts, penicillamine, or azathioprine. Methylprednisolone pulse therapy produced an immediate but temporary anti-inflammatory effect lasting for a maximum of four to eight weeks. It also caused a lasting depression of serum IgG, but no effect was observed on the proportion of T and B lymphocytes, proliferative responses, or on concanavalin A induced suppressor cell activity, and there was no effect on the amount of circulating immune complexes. The bone mineral content decreased similarly in the two groups, and methylprednisolone pulses had no effect on the progression of erosions on x rays during an observation period of eight months. A single pulse of methylprednisolone can give a short lasting anti-inflammatory effect but is of little or no value in the long term treatment of rheumatoid arthritis.

Randomised study of the influence of non-steroidal anti-inflammatory drugs on the treatment of peptic ulcer in patients with rheumatic disease.

Sixty-seven patients with rheumatic disease, treated with non-steroidal anti-inflammatory drugs (NSAIDs), entered a controlled trial with a diagnosis of duodenal (n = 51), gastric (n = 14), or gastric and duodenal (n = 2) ulcers. The main objectives of the study were a comparison of ranitidine and sucralfate in ulcer treatment, and to observe the influence of continued NSAID administration during peptic ulcer therapy. Ulcers healed within nine weeks in 52 patients. The mean healing time was similar in 27 patients given ranitidine 150 mg bd (4.9 weeks) and 25 patients given sucralfate 1 g qid (4.6 weeks). In patients with unhealed ulcers after nine weeks of treatment, healing was obtained in seven after further therapy for 3-9 weeks. Of the 30 patients who continued NSAIDs during treatment with either ranitidine or sucralfate, 23 ulcers healed (mean healing time: 5.0 weeks). Of 32 patients in whom NSAIDs were stopped, ulcer healing was documented in 29 (mean healing time: 4.6 weeks). The difference in healing rates was not statistically significant (p greater than 0.10). The outcome of ulcer treatment did not differ in patients with rheumatoid arthritis and patients suffering from osteoarthritis. During a 12 month follow up 14 symptomatic ulcer recurrences were recorded.
