Combination of methotrexate and sulphasalazine vs methotrexate alone: a randomized open clinical trial in rheumatoid arthritis patients resistant to sulphasalazine therapy.

To compare efficacy, toxicity, and the pharmacokinetics of the combination of sulphasalazine (SASP) and methotrexate (MTX) vs MTX alone in the treatment of SASP-resistant RA we conducted a controlled open clinical trial. Forty RA patients with active arthritis despite adequate SASP therapy, were allocated randomly to regimes of either SASP+MTX or MTX alone. The patients were evaluated openly by a single observer for 24 weeks. In the first 15 patients using the combination, pharmacokinetics of MTX without and with SASP were studied. Thirty-eight patients completed the trial. The mean decrease in the disease activity score in the group of patients receiving the combination was significantly greater than in the MTX group (-2.6 vs -1.3 respectively). The same pattern was seen concerning the other efficacy variables. There was no difference in the occurrence of toxicity. SASP had no influence on the pharmacokinetics of MTX. In conclusion in this open study the efficacy of the combination of MTX and SASP seems to be superior to MTX alone, the toxicity of both therapies was similar. This effect was not explained by the pharmacokinetics of MTX which were not altered by concomitant SASP administration.

Hyperimmunoglobulinemia D and periodic fever syndrome. The clinical spectrum in a series of 50 patients. International Hyper-IgD Study Group.

We studied 50 patients (28 male and 22 female) with the hyper-IgD and periodic fever syndrome. Most patients originated from Europe, namely The Netherlands (28 cases; 56%), France (10 cases, 20%), and Italy (3 cases, 6%), but 1 patient was from Japan. A hereditary component is suggested by 18 patients coming from 8 families. The syndrome is typified by a very early age at onset (median, 0.5 years) and life-long persistence of periodic fever. Characteristically, attacks occur every 4-8 weeks and continue for 3-7 days, but the individual variation is large. Attacks feature high spiking fever, preceded by chills in 76% of patients. Lymphadenopathy is commonly present (94% of patients). During attacks, 72% of patients complained of abdominal pains, 56% of vomiting, 82% of diarrhea, and 52% of headache. Joint involvement is common in the hyper-IgD syndrome with poly-arthralgia in 80% and a non-destructive arthritis, mainly of the large joints (knee and ankle), in 68% of patients. Eighty-two percent of patients reported skin lesions with some attacks; these demonstrated vasculitis histologically. Serositis has been seen in only 3 patients (6%), while amyloidosis has not been recorded in any of the patients with this syndrome. Immunizations precipitated attacks in 54% of patients. All patients had a persistently elevated serum IgD level (> 100 U/mL), and in 82% of cases the serum IgA was likewise elevated. During attacks there is an acute-phase response adjudged by leukocytosis, neutrophilia, and increased ESR. The etiology remains to be elucidated, and treatment is supportive. The hyper-IgD syndrome is distinct from other periodic fever syndromes like systemic-onset juvenile rheumatoid arthritis, adult-onset Still disease, and familial Mediterranean fever.

[The effect of admission to a geriatric department of a general hospital on drug consumption of the elderly].

Admission to a geriatric department of a general hospital of 100 elderly patients admitted in succession, resulted in a slight decrease in number of the prescribed medication. The data were gathered retrospectively. Cardiovascular drugs accounted for the main decrease, sedatives and laxatives showed the highest increase. The use of diuretics is significantly associated with dehydration; 43% of the users of diuretics were dehydrated. The most striking conclusion was that 25% of the prescriptions could be stopped for lack of indication.
