RESUMO

OBJECTIVE: To compare the efficacy and toxicity of cyclosporin A (CsA) monotherapy with CsA plus methotrexate (MTX) combination therapy in patients with early rheumatoid arthritis (RA). PATIENTS AND METHODS: 120 patients with active RA, rheumatoid factor positive and/or erosive, were randomly allocated to receive CsA with MTX (n=60) or CsA with placebo (n=60). Treatment with CsA was started in all patients at 2.5 mg/kg/day and increased to a maximum of 5 mg/kg/day in 16 weeks. MTX was started at 7.5 mg/week and increased to a maximal dose of 15 mg/week at week 16. Primary outcomes were clinical remission (Pinals criteria) and radiological damage (Larsen score), at week 48. RESULTS: Treatment was discontinued prematurely in 27 patients in the monotherapy group (21 because of inefficacy, and six because of toxicity) and in 26 patients in the combination therapy group (14 and 12, respectively). At week 48, clinical remission was achieved in four patients in the monotherapy group and in six patients in the combination therapy group (p=0.5). The median Larsen score increased to 10 (25th, 75th centiles: 3.5; 13.3) points in the monotherapy group and to 4 (1.0; 10.5) points in the combination therapy group (p=0.004). 28/60 (47%) of patients in the monotherapy group v 34/60 (57%) of patients in the combination therapy group had reached an American college of Rheumatology 20% (ACR20) response (p=0.36) at week 48; 15/60 (25%) v 29/60 (48%) of patients had reached an ACR50 response (p=0.013); and 7 (12%) v 12 (20%) of patients had reached an ACR70 response (p=0.11). Their was a tendency towards more toxicity in the combination therapy group. CONCLUSIONS: In patients with early RA, neither CsA plus MTX combination therapy nor CsA monotherapy is very effective in inducing clinical remission. Combination therapy is probably better at improving clinical disease activity, and definitely better at slowing radiological progression. Combination therapy should still be compared with methotrexate monotherapy.

RESUMO

This double-blind, randomized, multi-center study compared the metabolic tolerance of a combined formulation containing estradiol (E2) and trimegestone (TMG) with a standard hormone replacement therapy (HRT) containing estradiol valerate (EV) and norgestrel (NG). Blood lipids, glucose and fibrinogen concentrations were measured in the study which was conducted over 13 cycles, each of 28 days, and included 634 subjects in two randomized groups. A total of 481 subjects completed the study. The circulating concentrations of high density lipoprotein (HDL), HDL2, HDL3 cholesterol and apolipoprotein A1 were increased in the E2 + TMG group and reduced in the EV + NG group. Total cholesterol, low density lipoprotein (LDL) cholesterol, apolipoprotein B and lipoprotein(a) concentrations were decreased in both treatment groups; however, the reduction in LDL cholesterol was greater in the E2 + TMG group. Similar lipid findings were found in a subgroup that excluded subjects who had less than 3 months washout from a previous HRT, who provided a blood sample outside the day 17-28 window, or who were taking beta-blockers or thiazide diuretics. Blood glucose concentrations were reduced slightly in both treatment groups. A significant reduction in fibrinogen was also seen in both groups over the course of the study. The changes in lipid profile, especially HDL cholesterol, were more beneficial in the E2 + TMG group in comparison with the EV + NG group. This reflects the lack of androgenic action of trimegestone in comparison with norgestrel, which exhibits an androgenic effect and prevents the estrogen-induced increase in HDL cholesterol. The results of the study suggest that the use of trimegestone in combination with E2 may be preferable to norgestrel because of the more favorable lipid profile.

RESUMO

This double-blind, randomized, multi-center study compared the efficacy and clinical tolerance of a combined formulation containing 2 mg estradiol (E2) and 0.5 mg trimegestone (TMG) with a standard hormone replacement therapy containing estradiol valerate (E2V) and norgestrel (NG) in the treatment of climacteric symptoms. The study was conducted over 13 cycles, each of 28 days, and involved 634 subjects, of whom 481 completed the study. The primary efficacy variable was the percentage of subjects who showed at least a 50% reduction from baseline in the mean daily number of hot flushes in cycle 3. This was observed in 98.5% of the subjects in the E2 + TMG group and 93.3% of the subjects in the E2V + NG group (95% confidence interval of the difference, -8.6, -1.9). Significant differences in favor of the E2 + TMG combination were observed in the reduction in the mean daily number and severity of hot flushes, and in the percentage of subjects who had hot flushes at baseline but no hot flushes during treatment. There were no significant differences between the treatments in the Kupperman index and in urogenital signs or symptoms. Treatment with the E2 + TMG combination was well tolerated and the incidences of adverse events were similar in the two treatment groups. Breast pain was the main adverse event, possibly related to treatment that resulted in discontinuation. The mean number of bleeding days per cycle was significantly lower with the E2 + TMG combination than with the E2V + NG combination. The incidences of endometrial hyperplasia were low and comparable in both treatment groups. It was concluded that the E2 + TMG combination was either equivalent or superior to the E2V + NG combination in the treatment of hot flushes and other climacteric symptoms, and that its bleeding profile was favorable.

RESUMO

Prospective multicenter evaluation of the WHO classification and the morphometric D-score to predict endometrial hyperplasia cancer progression. In 132 endometrial hyperplasias WHO classification was performed by two experienced gynecologic pathologists. The D-score was assessed blindly by technicians in a routine diagnostic setting. Development of endometrial carcinoma during a 1-10-year follow-up was used as the end point. Eleven of 132 patients (8%), 10 of 61 (16%) atypical hyperplasias, and 1 of 71 (1%) nonatypical hyperplasias developed cancer. Twenty-six curettings had a D-score < or = 0 ("unfavorable" or endometrial intraepithelial neoplasia) of which 10 (38%) developed cancer. None of the 86 cases with a D-score > 1 ("favorable") and one of the 20 (5%) cases with 0 < D-score < or = 1 ("uncertain") developed cancer. Sensitivity of the D-score was 100%, specificity 82%, the positive and negative predictive values were 38% and 100%, respectively. These values are similar to those in three prior retrospective D-score studies but higher than the WHO values (which are 91%, 58%, 16%, and 99%, respectively). The D-score in endometrial hyperplasias is a more sensitive and specific marker for cancer prediction than the WHO classification, can be assessed in a routine clinical setting on standard hematoxylin and eosin sections (15-30 minutes per case), and is highly reproducible and cost-effective (U.S. $50 per case).

RESUMO

The aim of this study was to assess the value of Ki-67 immunoquantitation with a computerized image analysis system for grading support in cervical intraepithelial neoplasia (CIN). Sixty-five 'blind' consensus biopsies (23 CIN 1, 22 CIN 2, and 20 CIN 3) were used as a learning set. Measurements were done in the carefully selected most severely dysplastic part of the epithelium of each CIN case. The resulting discriminating combination of quantitative features was then prospectively applied on 121 new biopsies (test set) and compared with the classical CIN grade assessed routinely by six different pathologists and with the blind review grades assessed by two experienced pathologists. In the learning set of 65 cases, a jack-knifed stepwise discriminant analysis showed that the 90th percentile of the stratification index and the number of positive nuclei per 100 microm basal membrane are the best discriminating set of features to distinguish the three CIN grades at the same time. With these features, two CIN 1 cases were 'misclassified' as CIN 2 and nine CIN 2 cases as CIN 3. Overall agreement, therefore, was only 83%. However, recut of the paraffin blocks in the two 'misclassified' CIN 1 cases revealed CIN 2 in the first and CIN 3 in the other, while the other CIN 1 cases that were correctly classified with Ki-67 quantitation remained CIN 1. Likewise, nine CIN 2 cases were misclassified as CIN 3, but in two of these nine cases histological follow-up clearly indicated CIN 3. Agreement may thus be higher than the 83% in the learning set suggests. In the subsequent prospective evaluation on 121 routine CIN cases (test set), agreement between routine CIN grades (by six independent different pathologists) and quantitative Ki-67 classification was 78%. However, when compared with the blind review CIN grades of two expert pathologists, agreement was 97% and sensitivity, specificity, and positive and negative predictive value were very high. It is concluded that Ki-67 immunoquantitation is a useful diagnostic adjunct to distinguish different CIN grades and may also be a sensitive biological indicator of progression of seemingly low-grade CIN.

RESUMO

OBJECTIVE: To assess the contraceptive reliability, cycle control and tolerability of a new monophasic oral contraceptive containing 30 g ethinylestradiol plus 3 mg drospirenone (Yasmin, Schering AG, Berlin, Germany), it was compared with an established oral contraceptive containing 30 g ethinylestradiol plus 150 g desogestrel (Marvelon, NV Organon, Oss, The Netherlands). METHODS: A randomized, open-label, 13-cycle study was performed at 80 European centers. Contraceptive reliability, cycle control, blood pressure, body weight, the incidence of adverse events and skin condition were assessed during 13 cycles of oral contraceptive use, and at follow-up. Subjects recorded body weight on three consecutive days pretreatment and weekly thereafter. RESULTS: Of 2069 women who started the study and received the trial preparations in a ratio of 4:1 (ethinylestradiol/drospirenone, n = 1657; ethinylestradiol/desogestrel, n = 412), 1615 completed the 13 cycles plus follow-up, providing data for over 23,000 evaluable cycles. Eleven pregnancies occurred during treatment, only one of which (in the ethinylestradiol/drospirenone group) could not be ascribed to user failure or interaction with other factors. Both preparations provided effective contraception and cycle control. Pre-existing acne and seborrhea were improved and blood pressure was essentially unchanged. The two treatments differed in their effect on body weight, the difference being statistically significant. In the ethinylestradiol/drospirenone group, there was a distinct decrease over the whole treatment phase, while a subtle and less distinct decrease was documented in the ethinylestradiol/desogestrel group. CONCLUSIONS: The combination of 30 g ethinylestradiol/3 mg drospirenone provides effective oral contraception, excellent cycle control, good tolerability and a level of weight loss that may have a significant beneficial effect on compliance in women with a tendency to weight gain due to water retention.

RESUMO

If rheumatoid arthritis (RA) patients with a mild disease course could be identified early in the phase of the disease, therapy with less aggressive and probably less toxic antirheumatic drugs seems to be rational. The aim of this study was to investigate which factors at baseline could predict a clinical response (American College of Rheumatology preliminary response criteria) after treatment with chloroquine for 16 weeks. Two hundred and three early RA patients with active disease were treated with oral chloroquine sulphate (Nivaquine) at a daily dose of 300 mg during the first 4 weeks, 200 mg during the second 4 weeks and 100 mg thereafter. One hundred and eighty-three patients (90%) completed the study and 20 patients prematurely discontinued treatment. Of all the patients, 43 patients (21%) met the response criteria. A low level of C-reactive protein (CRP) was the only independent predictor for clinical response [relative risk: 0.97 (95% confidence interval: 0.95-0.98)]. It was concluded that a clinical response to chloroquine therapy in early RA patients can be predicted by a low CRP level at baseline.

RESUMO

OBJECTIVES: To investigate (1) whether the increase in serum creatinine observed during cyclosporin A (CsA) therapy was reversible in a group of patients with rheumatoid arthritis (RA) treated before the current guidelines for safe use in RA were developed and (2) whether the application of these guidelines prevents serum creatinine increases in the long term. PATIENTS AND METHODS: Eighty-three RA patients who had started low-dose CsA therapy between September 1990 and October 1992, and who were treated according to guidelines that allowed a 50% rise in serum creatinine, were tested for serum creatinine levels in December 1995 if they had discontinued CsA for at least 3 months. Predictors for irreversibility of renal function were determined by using multiple regression analysis. RESULTS: The mean level of serum creatinine gradually increased from 69+/-14 (mean+/-S.D.) micromol/l when starting CsA therapy to 88+/-23 micromol/l (28% above baseline) at the moment of CsA discontinuation, and had decreased to 80+/-17 micromol/l (16% above baseline) at follow-up, 35+/-14 months after drug discontinuation. During CsA therapy, the mean level of serum creatinine had increased to 82+/-19 micromol/l (26% above baseline) at 6 months and to 87+/-22 micromol/1 (39% above baseline) at 42 months. The mean CsA dose had decreased from 3.1+/-0.9 mg/kg/day at 6 months to 1.9+/-0.8 mg/kg/day at 42 months. The absolute number of months that serum creatinine levels were > 30% above baseline was an independent predictor for a persistent increase of the serum creatinine after CsA discontinuation. More than 2 months with a serum creatinine increase of > or = 30% resulted in a higher percentage irreversible increase than for less than 2 months with a > or = 30% increase: 27 and 6%, respectively (P < 0.0001). CONCLUSION: Long-term low-dose CsA administration in RA patients was associated with an increase in serum creatinine which was partially irreversible after drug discontinuation. The increase in serum creatinine was completely reversible in the patient group that was treated according to the current guidelines for safe use of CsA.

RESUMO

OBJECTIVE: To evaluate the cyclosporin A (CSA)-attributed risk of developing malignancies in general and malignant lymphoproliferative diseases (LPDs) and skin cancers in particular, as well as the CSA-attributed incidence of mortality in patients with rheumatoid arthritis (RA). METHODS: In a retrospective, controlled cohort study, the incidence of malignancies and mortality was evaluated in 208 CSA-treated patients with RA compared with 415 matched control patients with RA between 1984 and 1995. Patients were followed up for a median of 5.0 years (range 1.4-12.0). RESULTS: Forty-eight cases of malignancy (8 in the CSA group and 40 in the control group; relative risk [RR] 0.40, 95% confidence interval [95% CI] 0.19-0.84) were identified, of which 8 were malignant LPDs (2 CSA versus 6 control; RR 0.67, 95% CI 0.14-3.27) and 14 were skin cancers (2 CSA versus 12 control; RR 0.33, 95% CI 0.08-1.47). Seventy-three patients died (16 CSA versus 57 control; RR 0.56, 95% CI 0.33-0.95) due primarily to cardiovascular diseases (4 CSA versus 22 control; RR 0.36, 95% CI 0.13-1.04) or a malignancy (3 CSA versus 8 control; RR 0.67, 95% CI 0.18-2.43). Proportional hazards regression analysis with correction for potential confounding factors did not significantly change the results. CONCLUSION: The study findings suggest that CSA treatment in RA patients does not increase the risk of malignancies in general or the risk of malignant LPDs or skin cancers in particular. Moreover, the incidence of mortality in CSA-treated RA patients was comparable to that in matched control RA patients.

RESUMO

OBJECTIVE: To investigate whether there is interaction between chloroquine and cyclosporine (CyA) at the level of efficacy and toxicity in patients with recent onset rheumatoid arthritis (RA). METHODS: Eighty-eight patients with recent onset RA, who had shown a suboptimal clinical response on low dose chloroquine monotherapy, were randomly assigned to additional treatment with placebo, CyA 1.25 mg/kg/day, or CyA 2.50 mg/kg/day (fixed doses) for another 24 weeks. The tender joint count was the primary outcome assessment of efficacy and the serum creatinine of toxicity. The 1995 preliminary ACR response criteria for improvement were applied to evaluate individual clinical responses. RESULTS: Two patients in the placebo group (n = 29), 7 patients in the CyA 1.25 mg group (n = 29), and 8 patients in the CyA 2.50 mg group (n = 30) (p = 0.06) discontinued study medication prematurely for inefficacy or adverse events. The intention-to-treat analysis revealed that the tender joint count decreased 2.2 +/- 6.1 (mean +/- SD) joints in the placebo group, 2.2 +/- 6.6 joints in the CyA 1.25 mg group, and 5.0 +/- 5.8 joints in the CyA 2.50 mg group (p = 0.04). The 1995 preliminary ACR response criteria for clinical improvement were met by 8 (28%) patients in the placebo group, 10 (34%) patients in the CyA 1.25 mg group, and 15 (50%) patients in the CyA 2.50 mg group (p = 0.07). The serum creatinine increased 2 +/- 7 micromol/l in the placebo group, decreased 1 +/- 8 micromol/l in the CyA 1.25 mg group, and increased 10 +/- 15 micromol/l in the CyA 2.50 mg group (p < 0.001). CONCLUSION: The addition of low dose CyA is moderately effective in patients with early RA already treated with low dose chloroquine, but results in statistically significant renal function loss.

RESUMO

Meloxicam is a new nonsteroidal anti-inflammatory drug (NSAID), which, in animal tests, displays a high potency for anti-inflammatory and analgesic action. The aim of this study was to investigate the efficacy and tolerability of 15 mg meloxicam in comparison with 100 mg slow-release diclofenac in patients with osteoarthritis of the knee. Two hundred and fifty-eight patients were included in the intent-to-treat analysis; these were randomized into two groups to receive either 15 mg meloxicam (N = 128) or 100 mg diclofenac (N = 130) for a period of 6 weeks. The results with respect to efficacy showed a trend in favor of meloxicam regarding pain on movement, global efficacy and paracetamol consumption, although these differences did not reach statistical significance. The most frequently-occurring adverse events in both groups were of a gastrointestinal (GI) nature. However, there was a higher incidence (26 vs 16%) of GI adverse events in the diclofenac group compared with the meloxicam group. Both drugs were well tolerated when assessed by the patients on a visual analog scale (VAS). Thus, 15 mg meloxicam is an effective and well-tolerated therapy for osteoarthritis and compares favorably with diclofenac 100 mg, a well-established treatment for this indication.

RESUMO

Forty-four patients with early RA who had participated in a six months double-blind trial, comparing cyclosporine A (CsA) (n = 22) with chloroquine (Chl) (n = 22), were followed for a further 18 months irrespective of their treatment status. At two years follow up, the mean CsA dose was 2.7 +/- 1.1 mg/kg/day (n = 15) and the dose of Chl (n = 11) was 100 mg/day in every patient. Maximal difference in efficacy (represented by the percentage of patients who fulfilled the Paulus 50% response) was reached at one year (CsA group: 68% and Chl group: 36%; p = 0.07). At two years, the differences in efficacy and toxicity between the two groups had diminished. The conclusions of this follow-up study are: 1. maximal efficacy of low dose CsA in early RA patients is reached after one year of therapy. 2. CsA can maintain clinical efficacy and safety comparable to Chl for a period of at least two years.

RESUMO

The relative bioavailability of cyclosporin A (CsA) from a new microemulsion oral formulation (NEO) and the currently used soft gelatine capsule (SGC) was determined at steady state in 12 patients with rheumatoid arthritis. The AUC(0,12 h) values of cyclosporin A were significantly greater after NEO than SGC (2873 +/- 848 ng ml-1 h (mean +/- s.d.) vs 2355 +/- 1128 ng ml-1 h; P = 0.02, 95% CI (confidence interval of the difference: 81 to 955 ng ml-1 h). Cmax values were significantly higher after NEO than after SGC (811 +/- 244 ng ml-1 vs 495 +/- 291 ng ml-1, P < 0.0001, 95% CI of the difference: 209 to 422 ng ml-1).

OBJECTIVE: To investigate in common clinical practice the toxicity/efficacy ratio of low dose cyclosporine A (CsA) in patients with advanced rheumatoid arthritis (RA) after 12 months CsA administration. METHODS: One hundred and two patients with RA were included in the study. The initial dose of CsA was 2.5 mg/kg/day, the mean maximum dose was 3.2 mg/kg/day and the dose at 12 months was 2.8 mg/kg/day. RESULTS: Sixty-nine (68%) patients completed 12 months of treatment. Seventeen (17%) patients discontinued for lack of efficacy and 16 (16%) for toxicity (of which 50% for gastrointestinal intolerance). The clinical efficacy variables improved significantly by 36-42% between entry and Month 6 and remained stable thereafter. The C-reactive protein decreased from 43 U/ml at entry to 22 U/ml (p < 0.0001) at 12 months. Forty-four percent of the patients and 47% of the physicians judged the efficacy as good or very good. The median number of adverse events/patient was 3 but most adverse events were either not clinically important or disappeared after dose reduction. Gastrointestinal (GI) intolerance and nephrotoxicity (> 30% increase in serum creatinine) each occurred in 50% of the patients. GI intolerance was transient in 80% of the patients but accounted for 50% of the premature discontinuations for toxicity. Nephrotoxicity persisted in the 50% of the patients in whom it occurred, despite dose reduction. The mean serum creatinine rose from 70 (13) mumol/l at entry to 86 (23) mumol/l at 12 months (23% increase; p < 0.0001), and this increase had been entirely reached after 3 months. Variables that could significantly predict the occurrence of nephrotoxicity could not be identified. CONCLUSION: CsA can be safely and effectively administered to patients with RA for a duration of at least 12 months. An acceptable renal function at entry, close monitoring of the serum creatinine concentration and dose reductions when appropriate are prerequisities.

RESUMO

OBJECTIVE: To investigate whether low-dose cyclosporin A (CSA) is safe and effective in comparison with chloroquine (CQ) in patients with early rheumatoid arthritis (RA). METHODS: We performed a randomized, double-blind study comparing CSA with CQ in patients with early RA (duration < 2 years) who had had active disease for at least 3 months. Forty-four RA patients with a mean disease duration of 6 months were randomly allocated to receive CSA (initial dosage 2.5 mg/kg/day, maintenance dosage 3.6 mg/kg/day) or CQ (initial dosage 300 mg/day, maintenance dosage 100 mg/day) for 24 weeks. RESULTS: Five patients (2 taking CSA and 3 taking CQ) discontinued the study prematurely. Intention-to-treat analysis disclosed a decrease in the swollen joint count by 7 in both groups. The erythrocyte sedimentation rate and C-reactive protein level did not change significantly. CSA and CQ were tolerated equally well, although mild paraesthesia occurred more frequently in the CSA-treated group. The serum creatinine level increased by 13 mumoles/liter (95% confidence interval [95% CI] 4, 22) in the CSA group and by 6 mumoles/liter (95% CI 1, 11) in the CQ group (difference not statistically significant). CONCLUSION: Both CSA and CQ are effective in alleviating the symptoms of active early RA. There is only slightly impaired renal function after 24 weeks of drug administration of either drug in patients with early RA.

RESUMO

The efficacy and toxicity of cyclosporine in the treatment of patients with rheumatoid arthritis (RA) are reviewed. Most of the early trials were restricted to patients with intractable RA. The initial daily dose of cyclosporine was 5 to 10 mg/kg, which is now considered high. Of 283 cyclosporine-treated patients in nine studies, 8% discontinued the drug prematurely because of inefficacy and 17% because of adverse reactions. Cyclosporine improves clinical parameters but does not influence the erythrocyte sedimentation rate. The most important side effects are gastrointestinal intolerance and nephrotoxicity. The former is of minor importance with the present dosage schedule (starting daily dose, 2.5 mg/kg), and increments should follow the principle "go low, go slow." Guidelines are given to avoid or reduce nephrotoxicity. It may be beneficial to administer cyclosporine early in the course of RA.

RESUMO

Seventy-three patients with undiagnosed arthritis of undetermined aetiology, 94 patients with classified arthritis (rheumatoid arthritis, ankylosing spondylitis, etc.) and 70 controls were studied for clinical and serological manifestations of Lyme borreliosis. The patients were recruited from the three rheumatology units in the most southern part of The Netherlands. A clinical diagnosis of possible Lyme borreliosis was made in seven of 73 patients with arthritis of undetermined aetiology, in four of 94 patients with classified arthritis and in one of the controls. A definite diagnosis of Lyme borreliosis could be made in only one patient who belonged to the arthritis of undetermined aetiology group. This patient had erythema migrans, arthritis of the knee joint and showed positive antibodies to B. burgdorferi. In the southern part of The Netherlands, Lyme arthritis does not seem to be a frequent cause of arthritis of undetermined aetiology.

RESUMO

Plasma viscosity (PV) and erythrocyte sedimentation rate (ESR) are considered to reflect the complex of acute phase reactants in inflammations. Both tests were studied with regard to their ability to discriminate between inflammatory and non-inflammatory rheumatic diseases. PV and ESR were measured using the Coulter Viscometer II and the Westergren method, respectively. ESR was found to be a better parameter for rheumatoid arthritis and ankylosing spondylitis than PV, independent of the chosen reference values, age, gender and the hemoglobin level. ESR may still be regarded as an acceptable parameter for monitoring inflammatory rheumatic diseases.

RESUMO

OBJECTIVE: To determine whether hydrotherapy in a thermomineral institution is superior to the same hydrotherapy in an ordinary hospital exercise-bath. DESIGN: Controlled therapeutic trial. SETTING: The thermomineral institution at Arcen and the exercise bath at the Maasland Hospital in Sittard, the Netherlands. PATIENTS AND METHODS: 46 patients with rheumatoid arthritis were treated in a by a skilled physiotherapist, according to a standardized exercise-scheme: 27 were treated in the thermomineral institution and 19 (control-group) in the hospital exercise-bath. Each patient received 12 treatments in 12 weeks. ENDPOINTS PARAMETERS: Morning stiffness, erythrocyte sedimentation rate, Ritchie index, amount of pain, answers to 11 questions concerning the activities of daily life, and psychosocial aspects of the disease. The various subjective and objective parameters were scored by the same physician. RESULTS: Statistically significant improvement was observed in both groups concerning morning stiffness. Other subjective parameters improved, but did not reach significance. Objective parameters did not change significantly. Between-group differences were not found. CONCLUSION: Hydrotherapy has a positive effect on some subjective but not on objective parameters in patients with rheumatoid arthritis, whether it is applied in a thermomineral institution or an ordinary hospital exercise bath.

RESUMO

Ninety-two patients with active rheumatoid arthritis (RA) were entered in a randomized double blind study of 24 weeks comparing cyclosporine (initial daily dose 5 mg/kg) with D-penicillamine (initial daily dose 250 mg). The groups were well balanced in baseline characteristics. In the cyclosporine group, 10 patients stopped prematurely, one because of inefficacy. In the D-penicillamine group, 9 patients stopped prematurely, 3 because of inefficacy. The 2 antirheumatic drugs were equally effective in reducing disease activity, except for a significant (p = 0.005) decrease in erythrocyte sedimentation rate with D-penicillamine treatment. We conclude that under the conditions of this trial, cyclosporine can serve as an alternative to D-penicillamine for the treatment of patients with RA.
