A case of interstitial pneumonia in polymyositis difficult to distinguish from gold pneumonitis

Rheumatoid arthritis was diagnosed in a 48-year-old woman. She received a gold compound, and 4 weeks after the start of that therapy, interstitial pneumonia appeared. Findings from a muscle biopsy, and high serum CPK and LDH levels indicated that she suffered from polymyositis rather than rheumatoid arthritis. The result of a drug lymphocyte stimulation test (DLST) for the gold compound was more than 200%. Because the usefulness of the DLST for the gold compound in the diagnosis of gold pneumonitis is not thoroughly established, the DLST was also done in patients with rheumatoid arthritis who were receiving the gold compound without side effects, and in normal subjects. Many of the rheumatoid arthritis patients and some of the normal subjects had a positive response to the gold compound. Therefore a positive response on the DLST for the gold compound does not always support the diagnosis of gold pneumonitis.     

Prevalence of gold contact hypersensitivity in the west of Scotland

373 patients attending for routine patch testing were tested with 0.5% and 0.05% gold sodium thiosulfate (GST). 8 (2.1%) patients had a positive patch test, and a further 4 (1.0%) patient reactions which were interpreted as irritant 2 out of 8 patients with a positive patch test to GST suspected gold allergy prior to testing, and both of these patients reported that their eczema resolved if they avoided gold jewellery. This is the lowest prevalence of hypersensitivity to GST reported and suggests that gold contact allergy may not be as widespread as has been recently proposed.     

Treatment of pemphigus with gold

BACKGROUND: Although gold has been reported to be useful in treating pemphigus vulgaris, its use has waned in recent years because of concerns regarding efficacy and toxicity. OBJECTIVE: To review 26 patients with pemphigus who were treated with intramuscular gold over a 10-year period. RESULTS: Gold was effective in 62% of patients as a primary treatment for pemphigus or as a steroid-sparing agent. An average of 3 months of therapy was required before the daily prednisone dosage could be halved. Four patients were free of disease and stopped receiving all therapy at the conclusion of the study. Toxic effects due to gold therapy developed in 42% of patients and all adverse effects resolved with its cessation. CONCLUSIONS: While toxic effects limit the use of gold in many patients with pemphigus, it may be effective in treating a large percentage of patients who otherwise are unable to reduce their steroid requirement. Because of its delayed onset of action, patients treated with gold usually require systemic steroids when therapy is initiated. Controlled, prospective trials are needed to further evaluate the efficacy of gold and its potential steroid-sparing effects.     

Adverse reactions to D-penicillamine after gold toxicity

The incidence of adverse reactions to D-penicillamine in 155 patients with rheumatoid arthritis was analysed and compared with their history of adverse reactions to gold. Out of 125 patients who took only D-penicillamine, 45 developed side effects from the drug, whereas of 27 patients with a history of gold toxicity, 18 also reacted adversely to D-penicillamine. All patients who took D-penicillamine within six months after an adverse reaction to gold developed side effects from D-penicillamine. Fourteen patients developed similar adverse reactions to D-penicillamine and gold, and the interval between treatments in this group was significantly shorter (p less than 0.01) than in those who developed either differing adverse reactions to both drugs or no reaction to D-penicillamine after treatment with gold. An interval exceeding six months between treatment with gold and treatment with D-penicillamine in patients who have developed adverse reactions to gold apparently reduces the risk of adverse reactions to D-penicillamine.     

Amyloidosis--incidence and early risk factors in patients with rheumatoid arthritis

In a 15-year follow-up examination, reactive secondary amyloidosis (RSA) was found by subcutaneous fat biopsy in six out of 74 still living patients (8.1%) of an original population of 102 with erosive and seropositive rheumatoid arthritis (RA). Five of the 24 deceased patients had had RSA. Thus the 15-year incidence of RSA in RA was at least 10.9% (11/102). To study early prognostic aspects of RSA, comparison was made of 14 entry variables and the initial treatment in the RSA group (n = 11) and the control group (n = 81) respectively. At onset (< or = 6 months) of RA only serum orosomucoid, but after three years morning stiffness, ESR, serum CRP and orosomucoid were significantly worse in patients whom later developed RSA. Three out of 48 patients treated with gold sodium thiomalate and seven out of 30 treated with chloroquine developed RSA (p = 0.04). It is concluded that continuously active disease was the risk factor underlying RSA. The role of early chloroquine therapy is discussed.     

Progression of joint damage in early active severe rheumatoid arthritis during 18 months of treatment: comparison of low-dose cyclosporin and parenteral gold

OBJECTIVE: This study compared the progression of joint damage in patients with early active severe rheumatoid arthritis (RA) treated with cyclosporin or parenteral gold. METHODS: In this open, randomized, multicentre study with a blinded radiological endpoint, 375 patients who had suffered from active severe RA for <3 yr were randomized to be treated for 18 months with low-dose cyclosporin or parenteral gold. The groups were stratified with regard to corticosteroid use. Primary efficacy variables were numbers of erosions, erosion score and the Larsen-Dale joint damage score. RESULTS: Joint damage progressed at similar rates in both treatment arms. In both groups, patients receiving corticosteroids had less X-ray progression. Rheumatoid factor positivity, high swollen joint count, high erythrocyte sedimentation rate and pre-existing X-ray abnormalities predicted progression of joint damage. Although numbers of serious adverse events were similar, more gold patients (n = 65) than cyclosporin patients (n = 45) withdrew from study medication because of adverse events. CONCLUSION: Cyclosporin was comparable to parenteral gold in retarding progression of joint damage and was better tolerated in terms of adherence to therapy. The open label design should be kept in mind when assessing this difference.     

Ocular chrysiasis correlated with gold concentrations in the crystalline lens during chrysotherapy

The eyes of 11 patients with rheumatoid arthritis (RA) who received extended chrysotherapy (mean cumulative dose greater than 7 grams during a mean 6-year period) were examined biomicroscopically. Minute reddish-purple particles were seen in the cornea (corneal chrysiasis) in 5 and in the lens (lens chrysiasis) in 4 patients. Particulate deposits were absent in 11 other RA patients who had not received gold treatment. Seven crystalline lenses from 5 gold-treated patients were removed surgically because of incidental cataract formation and analyzed for gold content using neutron activation analysis. Although the mean lens gold concentration was higher in these patients than in non-gold-treated controls without RA (0.0073 microgram/grams versus 0.001 microgram/grams), the absolute gold level was markedly lower than that found in 25 diverse tissue analyzed previously. This finding is compatible with the absence of clinical gold-related lens disease or visual impairment.     

Modern medical management of pulmonary tuberculosis

Varicoid was administered to 170 patients with rheumatoid arthritis, to 11 patients with a diagnostically uncertain monarthritis, to 12 patients with exudative gonarthrosis and also to 4 patients with lupus erythematodes visceralis. A total of 262 joints were treated. The short-term results, which were evaluated 4 weeks after the administration of Varicocid, revealed improvement is 95% of the patients. After 12 months, 46% of the patients were found to be free from symptoms within the area of the treated joint, and 33% of the patients showed a considerable improvement. An objectively evident improvement was found in 35 out of 40 patients with rheumatoid arthritis followed up over a period of 3 years. Comparable results after treatment with Varicocid were also obtained in patients suffering from any one of the above-mentioned rheumatic diseases. A new inflammation activity/function index for the evaluation of the local joint therapy has been used. The first investigations both of function and of morphology of the synovial membrane treated with Varicocid are reported. In our opinion, chemical synovectomy with Varicocid fills a gap in the therapy of the rheumatoid arthritis. The essential value of this type of therapy is the absence of toxicity, a temporary increase in local reactions only, and also a continuous improvement, especially in early cases.     

Gold: an allergen of growing significance

Gold moved into the limelight of medical literature thanks to the anti-inflammatory activity and effectiveness of gold compounds in the treatment of rheumatoid arthritis, but more recently also because of the growing incidence of hypersensitivity induced by it which is expressed in cutaneous and mucosal reactions. This review discusses dermatotoxicity associated with gold. In some countries gold has moved into second place as allergen, following nickel. Such recognition is mainly due to improved diagnostic methods and to its inclusion in routine dermal patch testing. Some unconventional manifestations of hypersensitivity are associated with use patterns which involve intimate contact with the metal as a component of jewelry. In-depth analysis of the growing number of cases of allergy has revealed various immunological idiosyncrasies as being characteristic of this metal. These include late reactions to challenge, extraordinary persistence of clinical effects, formation of intracutaneous nodules and immunogenic granuloma unresponsive to conventional steroid therapy, the occurrence of eczema at sites distant from the site of contact, and flare-ups of eczema upon systemic provocation with allergen which are characteristic of drug induced allergy. These manifestations demand investigations at the molecular level of the unusual mechanisms of action involved.     

Tumors in rheumatoid arthritis

Benign (bTu) and malignant tumours (mTu) were studied in a randomised autopsy material of 161 patients with rheumatoid arthritis (RA). The tissue specimens were fixed in 8% formaldehyde solution at pH 7.6 and embedded in paraffin. The tumours were diagnosed histologically and confirmed by immunohistochemical methods. Five benign (3.1%), and thirteen malignant tumours (8.1%) found observed in 18 (11.2%) of 161 cases. There was no significant difference between laboratory parameters of patients with malignant tumours and without tumours. One benign (0.62%) and seven malignant (4.35%) tumours led to death in 8 (4.97%) of 18 cases altogether. Neoplasms were detected clinically in 8 of 18 cases (44.4 rel%). None of tumorous patients received immunosuppressive treatment and only five had gold (Tauredon) therapy. Paraneoplastic syndromes with rheumatoid complaints may be excluded by the onset and duration of RA and tumours. Benign neurogenic tumours and malignant bronchioloalveolar carcinoma were frequently associated with RA not treated by immunosuppressive drugs. Our data do not support the assumption of a high risk of malignant lymphomas associated with RA treated with immunosuppressive therapy.     

Sesame oil in injectable gold: two drugs in one?

To investigate the potential anti-inflammatory effects of sesame oil, which is present in the injectable gold preparation Auromyose, the synthesis of tumour necrosis factor alpha (TNF-alpha), prostaglandin E2 (PGE2) and leukotriene B4 (LTB4) by in vitro stimulated blood cells was measured before, during and after 12 weeks of dietary supplementation with 18 g of sesame oil daily in 11 healthy male volunteers. Neither TNF-alpha, PGE2 nor LTB4 production levels showed statistically significant changes during the 12 weeks of dietary supplementation with sesame oil. These results do not suggest an anti-inflammatory effect of sesame oil as present in injectable gold preparations which are used in the treatment of rheumatoid arthritis.     

Do minocycline and other tetracyclines have a place in rheumatology?

Tetracyclines are a family of antimicrobials with activity against a broad range of organisms including those that develop intracellularly. Links have been reported between some infections and some inflammatory joint diseases, with the most notable example involving mycoplasmas and rheumatoid arthritis. Reactive arthritides are known to be triggered by organisms found in the gastrointestinal or genitourinary tract, and antigenic material from these organisms has recently been demonstrated in synovial tissue from patients with reactive arthritis. These facts led to the hypothesis that tetracyclines may be useful in rheumatoid arthritis and reactive arthritis. Two controlled studies found that minocycline benefited rheumatoid arthritis patients when it was given either as an adjunct to another second-line treatment or as the only slow-acting drug. Lymecycline has been found to expedite recovery from reactive arthritis due to Chlamydia trachomatis, and tetracycline to decrease the incidence of reactive arthritis due to sexually-transmitted diseases. The safety profiles of these treatments were acceptable in all available studies but require further investigation during long-term administration. The benefits may be related to the immunomodulating effects of tetracyclines and/or to their ability to inhibit metalloproteases such as collagenases. Whether tetracycline therapy influences the course of radiologic lesions in rheumatoid arthritis remains unknown. However, minocycline therapy has given sufficient proof of its efficacy to make it an attractive alternative in rheumatoid arthritis.     

A long-term five-year randomized controlled trial of hydroxychloroquine, sodium aurothiomalate, auranofin and penicillamine in the treatment of patients with rheumatoid arthritis

OBJECTIVE: To compare the efficacy of hydroxychloroquine, penicillamine, sodium aurothiomalate and auranofin in the treatment of active rheumatoid arthritis over a period of 5 yr. METHOD: Five hundred and forty-one patients with definite or classical rheumatoid arthritis were entered into an open randomized controlled trial with a flexible dose regimen designed to reflect clinical practice. Decisions to stop treatment with any one of the disease-modifying anti-rheumatic drugs (DMARDs) were based on an agreed trial protocol which defined criteria for adverse reactions and therapeutic failure. The managing physicians' decisions were confirmed in a separate monitor clinic. RESULTS: The proportion of patients who remained on their first DMARD or who were in remission at 5 yr was 53% for penicillamine, 34% for sodium aurothiomalate, 31%, for auranofin and 30% for hydroxychloroquine (P < 0.001). In patients who stayed on their first DMARD, all groups showed a 30-50% improvement in C-reactive protein, erythrocyte sedimentation rate, Ritchie Index and joint stiffness, and a deterioration in their Larsen score. There was no evidence of physician bias to explain the larger proportion of patients remaining on penicillamine for 5 yr. CONCLUSION: Despite the increased popularity of sulphasalazine and inmmunosuppressives, the drugs in this study continue to be used worldwide. The natural history of rheumatoid arthritis requires long-term follow up to establish drug efficacy. Evidence is needed as to whether the newer regimens will prove to be more effective and safer in the longer term than the commonly prescribed DMARDs. The data from this trial will provide a reference for comparison with future studies.     

Evaluation criteria in follow-up studies of flexor tendon therapy

Oxphenisatin is known to induce liver damage and is suspected to cause or perpetuate chronic liver disease. In order to evaluate the hepatotoxic effect of long-term therapy with oxyphenisatin 26 consecutive patients with rheumatoid arthritis were investigated for the presence of liver disease. In all cases, liver biopsy, biochemical liver function tests and determination of Hepatitis-B antigen were performed. Ten patients showed no pathological changes in the liver biopsy and a further 2 had only non-specific changes. Seven patients had fatty liver, 5 passive congestion, one haemosiderosis and only one had cirrhosis of the liver. No correlation was found between the activity of rheumatoid arthritis, and duration of the disease, the drug therapy given, and the liver damage.     

Institute of Rheumatology and progress of antirheumatic therapy

The paper deals with the achievements of the Institute of Rheumatology in antirheumatic therapy, among them there are methods of objective assessment of antirheumatic drugs, the first use of antimalarials in the treatment of chronic rheumatic fever, discovery of immunodepressive properties of these drugs, specification of the mechanism of action of several NSAIDs. Antilymphocytic globulin, salazopyridazine and the alkylating drug dopan were used for the first time in therapy of rheumatic diseases. Administration of the most potent NSAIDs diclofenac or indomethacin to patients with acute rheumatic fever proved to be as effective as prednizolone. Special attention is paid to the combination treatment of rheumatoid arthritis with NSAIDs. The concurrent administration of aurannofin and methotrexate was shown to cause a more rapid development of clinical improvement than monotherapy with either drug. A combination of gold aurothiomalate and hydroxychloroquine and that of low doses of D-penicillamine and cyclophosphamide had no advantages over monotherapy. Revealing the therapeutical potential of antibodies to interferon-gamma in the treatment of rheumatic arthritis and psoriatic arthritis was the most important achievement of recent years. These studies open new vistas for anticytokine treatment of rheumatic diseases.     

Treatment of rheumatoid arthritis of senile onset with methotrexate

Elderly onset rheumatoid arthritis is a not rare disease with relevant social implications. The most important question is represented by the therapeutic choice, in relation to the typical problems of the elderly patients and to the frequent coexistence of other diseases. In this work, we evaluated the practicability and the efficacy of methotrexate therapy, at the dose of 5 mg/week, in 27 patients affected by elderly onset rheumatoid arthritis (mean age 73.76 +/- 3.39 years, range 70-83). Low dose prednisone was associated in order to control painful symptoms. Also sulindac was allowed. Frequent clinical and hematochemical controls were made in order to precociously evaluate the appearance of side effects. All the 27 patients completed the first year of treatment; during this period there was no drop out. Sixteen patients finished the second year too; during this year one patient dropped out because of significant hypertransaminasemia and another patient did not respect the follow-up. Clinical and hematochemical parameters were monitored. A significant improvement of all data was observed from the third month. A further amelioration was recorded in the following months. Our data suggest the efficacy and the safety of low dose methotrexate in the treatment of elderly onset rheumatoid arthritis. A careful evaluation of side effects is obviously necessary.     

Latex allergy in health services workers

The studies were performed in 20 workers from the Health Service (13 women and 7 men in the age 25-57) suffering from hand urticaria (6 persons) and hand dermatitis (14 persons) suspected of the allergy to latex gloves. In all patients the familial and personal predispositions to allergy were evaluated by the anamnesis, the estimation of total IgE serum level and the skin prick tests (SPT) with inhalant allergens. The latex allergy was diagnosed by SPT and contact test with standardized extract of the natural latex allergen in the concentration 1000 PNU/ml (Nexter-Allergopharma) and by estimation of specific to latex IgE serum level. In addition to this, contact tests with glove's material as well European standard contact allergens (Hermal) were done and the one with antiseptic substances to which the patient was exposed at his work. The allergy type I to latex gloves was confirmed in all 6 cases with contact urticaria. The SPT with standard extract of the natural latex was more valuable than latex specific IgE in the serum. Contact allergy (type IV) to latex gloves was confirmed in 10 from 14 suspected cases. In the next 4 the allergy to antiseptic substances was the reasons of the illness. The allergy to latex gloves appears more often in women. No case showed the familial predisposition to allergy and only 4 patients additionally suffered from the allergy to pollen and mites. Moreover in both groups of patients we showed the presence of the additional contact allergy to different allergens (to metals and antiseptic substances).     

Cross-sectional epidemiological survey of rheumatoid arthritis patients seen in private practice in France. Descriptive results (1629 cases)

OBJECTIVE: To conduct an epidemiological study of rheumatoid arthritis patients seen by office-based rheumatologists in France (first semester of 1996). METHODS: Cross-sectional study of 1629 rheumatoid arthritis patients conducted by 373 office-based rheumatologists who volunteered for the study (one visit per patient). Each rheumatologist was to complete a 200-variable questionnaire for the first four rheumatoid arthritis patients who came to their office. RESULTS: Women contributed 81% of the sample (mean age, 57 years); 19% of patients were seen in the Paris area, 20% in the North East, 20% in the North West, 22% in the South East and 19% in the South West. Twenty-nine per cent of patients had a paid job and 21.1% (all women) were homemakers. Among the patients with a paid job, 44% were on sick leave, with the reason for the sick leave being the rheumatoid arthritis in 36% of cases. Nineteen per cent of patients had stopped working permanently because of their rheumatoid arthritis, after a mean disease duration of six years. Mean disease duration in the overall sample was eight years. The diagnosis was established within six months of symptom onset in 75% of cases. A family history of rheumatoid arthritis was found in 11% of patients and a family history of other autoimmune diseases in 2%. The disease was precipitated by a stressful life event in 17% of cases. Follow-up was being provided only by the study rheumatologist in 59% of cases and also by a general practitioner in 39%. The disease was quiescent in 9% of cases, minimally active in 32%, moderately active in 46% and severely active in 13%. Eighty-four per cent of patients were on one (78%) or more (6%) second-line drugs including methotrexate (45%), an antimalarial (17%), intramuscular gold (14%), tiopronin (9%), D-penicillamine (6%) and sulfasalazine (12%). Fifty-two per cent of patients were on steroid therapy (mean dose, 7.5 +/- 5.7 mg/d). Other drugs included nonsteroidal antiinflammatory agents (61%), analgesics (61%), gastroduodenal protective agents (45%) and anxiety-relieving agents (10%). Twenty-four per cent of patients had had one or more surgical procedures (mean, 3/patient) for their joint disease. CONCLUSION: This nation-wide epidemiological survey conducted in France provides a database on the socioeconomic and demographic characteristics of rheumatoid arthritis patients followed in private practice.     

How Canadian and US rheumatologists treat moderate or aggressive rheumatoid arthritis: a survey

OBJECTIVE: To determine which second line agents Canadian and US rheumatologists use to treat patients with active rheumatoid arthritis (RA). METHODS: A one page survey was sent by fax or mail to all 263 members of the Canadian Rheumatology Association and 320 members of the American College of Rheumatology (10% random sample weighted by region) known to practice adult rheumatology. The survey asked for first and second treatment preferences in patients with (1) aggressive RA; (2) moderate RA; and (3) aggressive RA failing a trial of methotrexate (MTX) 25 mg. RESULTS: Altogether 231 (87.8%) Canadian and 230 (71.7%) US rheumatologists responded, and 214 responses in each survey were analyzable. In aggressive RA. MTX was the drug of first choice of most Canadian (68.7%) and US (78.5%) rheumatologists. Intramuscular gold was a drug of first choice for 14.5 and 1.9% of Canadians and Americans, respectively. 93.9% of Canadian and 90.2% of US respondents preferred single agents for the treatment of moderate RA. Among US rheumatologists. no clear leader emerged as a single agent alternative for the management of aggressive RA unresponsive to MTX. Most said they would use combination (38.3%) or triple (23.8%) therapy involving MTX plus sulfasalazine and/or hydroxychloroquine. 52.3% of Canadians preferred single agent therapy, with 34.6% choosing gold as an alternative to MTX. CONCLUSION: Canadian and US rheumatologists preferred MTX for the treatment of aggressive RA. Canadian rheumatologists saw a small but significant role for intramuscular gold. No single agent emerged as a clear alternative to MTX among US rheumatologists.
