[Determination of the rheumatoid factor in gouty patients].

The authors have examined the incidence of the rheumatoid factor in the serum of a group of 100 patients, 95 males and 5 females, suffering from gout, of whom only 6 suffered from chronic gout. The rheumatoid factor in the serum was measured by RA-test (1:40) and by Waaler-Rose test (1:32). The rheumatoid factor was not present in the examined subjects and so we can state that such serum parameter does not represent, for its negativity, a laboratory index of any evidence in the gout and it doesn't represent a reason for diagnostic doubts with other forms with the rheumatoid factor in the serum.

[Determination of plasma levels of apolipoprotein E and of HDL-cholesterol in gouty patients].

The authors have examined the levels of the plasma cholesterol and triglycerides, of the plasma lipoprotein (HDL, LDL, VLDL) and of their main apolipoproteins (apo-A and apo-B) in a group of 34 patients affected by gout and in a population of healthy subjects considered as a contrast group, trying to establish a plausible dislipidemic factor which could justify the major occurrence of coronary heart disease in patients suffering from gout. Statistical analysis was done with the t-test. The group of patients affected by gout had significantly higher levels of triglycerides and VLDL-C and lower levels of HDL-C than the population of healthy subjects. The change of the lipoprotein pattern observed in the patients suffering from gout may be linked to reduction of the catabolism of the triglycerides rich lipoprotein. This reduction is probably linked to a inhibition of lipoprotein lipase.

[Rheumatoid cardiopathy. Observations on a clinical case].

The occurrence of cardiac involvement in RA is frequent but cardiac lesions are observed more frequently at necroscopy than on clinical examination. The case of a RA patient with a serious mitral valves involvement is reported in which the histological examination of the bioptic tissue obtained during surgical valves replacement showed a typical rheumatoid granulomatous inflammation of the endocardium.

A double-blind, interpatient comparison of plain and slow-release ketoprofen in osteoarthritis.

Eighty patients with osteoarthritis of various localization completed a double-blind, parallel-group trial of 2 weeks' duration comparing the efficacy and tolerance of ketoprofen slow-release capsules (150 mg) given either as a morning or a midday or an evening dose with that of ketoprofen conventional capsules (50 mg) 3X daily. All regimens were associated with a statistically significant improvement in pain at rest, pain on active motion, quality of sleep, and spine flexion, but there was no difference between treatments. The tolerance of ketoprofen was also similar in all groups. In view of the alleged better compliance of patients with once-daily medications, the new slow-release formulation of ketoprofen appears to be a useful alternative to the conventional capsules.

[Short-term effects of proglumetacin in arthrosis].

Proglumetacin was administered as a sole treatment during 15 days at 450 mg/day to 20 patients with osteoarthritis localized in several joints. Within the observation period, pain at rest and on loading, joint mobility and morning stiffness improved significantly. Tolerance also resulted very good, as only two patients reported mild and transient gastric upsets. The peculiar combination of good efficacy also in short-term treatment and very good tolerance, points to proglumetacin as a drug of choice for the ambulatory management also of degenerative-reactive joint disorders.

Hormonal aspects of human gout--excretion of adrenal hormone derivatives in gouty patients.

Forty-seven patients with gout, 28 of whom had not previously been treated with allopurinol, and 25 normal subjects, were examined for 24-h urinary excretion of the most important adrenal steroid derivatives. Results were submitted to statistical analysis and several variables have been taken in consideration. The untreated patients showed significantly higher values of uricemia, urinary uric acid, triglycerides, slightly higher values of androsterone, 11-oxo-androsterone + 11-oxo-etiocholanolone, dehydroepiandrosterone, and slightly lower values of 11-hydroxyandrosterone and pregnanetriol, in comparison to normal subjects. The different hormonal pattern seems to discriminate between patients with gout and normal subjects.

A short-term, double-blind comparison between indoprofen and diclofenac in osteoarthritis.

A double-blind crossover trial was carried out in 60 patients with osteoarthritis of large joints. Patients received both indoprofen 600 mg daily and diclofenac 100 mg daily for one week without any interval between treatments. The variables investigated were: pain at rest, pain on active motion under load, quality of sleep, articular flexion and patient's preference. The assessments were made before and at the end of each treatment period. Significant improvements were found for all variables with both drugs. No significant differences were detected between the two drugs. Ten patients (6 on indoprofen and 4 on diclofenac) reported adverse reactions i.e. slight gastralgia in most cases. No withdrawals of treatment were observed.

[Inhibition of fructose-induced hyperuricacidemia by pretreatment with phosphates].

To test the hypothesis that intravenous injections of fructose rapidly decreases liver ATP and Pi and results in the rapid degradation of adenine nucleotides and hyperuricemia, fructose was administered intravenously to a group of normal and gouty subjects; 4 gouty patients were treated with a phosphate solution prior fructose loading. The results obtained show that fructose administration plus phosphate solution prevents Pi depletion and inhibits fructose-induced hyperuricemia.

[Drug-induced changes in chemotaxis under normal conditions and in rheumatoid arthritis].

The effects of agents used in RA treatment, various drugs, RF, rheumatoid nodule and synovial fluid was studied on chemotaxis of PMNs. NSAIDS, corticosteroids, theophylline, colchicine, SOD, RF, rheumatoid nodule and synovial fluid were found to inhibit the chemotactic responsiveness while AMPc, GMPc, PGEI and immunodulator drugs enhanced chemotaxis. The results support the hypothesis that drugs tested may modulate chemotactic function by affecting cellular microtubules assembly and/or GMPc accumulation.

[The production of superoxide anion (O2-) by polymorphonuclear cells in patients with rheumatoid arthritis].

Superoxide anion production has been determined in controls and RA patients PMNs stimulated with zymosan, rheumatoid synovial membrane, nodule and synovial fluid, rheumatoid factor, aggregated gamma-globulins, Mycoplasma and Epstein-Barr virus. Patients with RA showed an increased production of O2- after incubation with zymosan and rheumatoid tissue extracts or synovial fluid in comparison to normal controls. The findings indicate that rheumatoid PMNs become activated by different stimuli to produce an excess of O2- which can contribute to chronic inflammatory process.

Indoprofen in rheumatic patients with acute episodes: a multicentre trial.

The results are reported of an open multicentre trial in 228 rheumatic patients with flare-ups. Fourteen centres adopting the same investigational protocol collaborated in the study. Indoprofen was administered for 1 week at a daily dosage of 1000 mg according to a treatment schedule used with success in acute gouty arthritis: a 400 mg i.v. bolus was followed by 200 mg (1 tablet) t.i.d. Subjective (pain) and objective variables were used for reliable assessment of activity. Marked reduction of pain intensity was already noticeable on day 1 of treatment and was followed by progressive improvement in subjective and objective variables for all the diagnoses considered. According to the patients' own overall assessments, results were good or very good in more than 50% of cases. The best outcomes were obtained in low back pain, acute gout and psoriatic arthritis. At the end of treatment only 7.4% of patients experienced no change or deterioration of symptoms. Adverse reactions, consisting mostly of mild and reversible gastrointestinal disturbances, were reported by 9.2% of patients, but only in 1.8% was treatment discontinued. Indoprofen administered according to the above schedule is an appropriate treatment for acute episodes of rheumatic diseases.

[Apical pulmonary fibrosis in the course of ankylosing spondyloarthritis].

Two cases of an association between lung TB and ankylosing spondyloarthritis are presented. In the first case, spondyloarthritis appeared about 1 yr after fibrocavitary lesions of the LSD. The literature contains only 1 similar case, in which the gap was two years. In the second case, such lesions appeared 8 yr after spondyloarthritis. Neither patient received radiation treatment. The first received cortisone for massive joint inflammation when typical lung TB lesions were already evident. It is felt that these two additions to the literature are of interest in clarifying the delicate questions of diagnosis that arise when ankylosing spondylarthritis is accompanied by lung involvement.
