Effect of androgen deprivation therapy on local symptoms and tumour progression in men with metastatic carcinoma of the prostate.

OBJECTIVE: To evaluate and compare the effects of medical or surgical castration combined with either nilutamide (Anandron) or placebo on symptoms of local tumour progression in men with carcinoma of the prostate. METHODS: The results from twin, randomised, prospective, placebo-controlled trials were analysed. 434 patients received nilutamide 300 mg/day for 1 month and 150 mg thereafter, and 434 received a matched placebo from either the day of orchidectomy or the first leuprolide injection. Before treatment, and at months 1, 3, 6 and every 6 months thereafter, urinary obstruction and tumour volume were evaluated. Data on adverse or intercurrent events affecting the urological system were documented. RESULTS: Before treatment, urinary obstructive symptoms and tumour volume were similar in both treatment groups. After treatment, improvement in urinary obstructive symptoms accompanied a decrease in prostate volume. The majority of men in both treatment groups reported an improvement in obstructive voiding symptoms. However, total adverse events secondary to local symptoms were significantly less frequent in the nilutamide-treated patients (20%) compared with the placebo-treated patients (35%). Only a small percentage of men in both treatment groups had disabling local symptoms and only 2% experienced problems with incontinence. CONCLUSIONS: Local symptoms from primary tumour growth are relatively common in patients with metastatic carcinoma of the prostate and are favourably influenced by hormonal therapy. In these trials, the problems resulting from local tumour progression were significantly fewer in the group treated with castration plus nilutamide compared with the group treated with castration plus placebo.

[Acadione, a new long-term treatment of rheumatoid polyarthritis].

This article summarizes the authors' experience and data from the literature regarding acadione, a medication like D-penicillamine with a thiol radical, in the treatment of rheumatoid arthritis. Two control studies versus placebo and two control trial versus D-penicillamine prove the effectiveness of the treatment and demonstrate a similar activity between 1 g of acadione and 600 mg of D-penicillamine. The side-effects of acadione are similar of those of D-penicillamine, essentially rash, toxic dermatitis, agueusia, proteinuria, which disappear upon discontinuation of the treatment. The fact that the patient exhibited a side effect with D-penicillamine, increases, the risk with acadione, but this is not systematic, which is the main advantage of this product.

[Tiopronine and rheumatoid polyarthritis].

This article summarises the authors' experience and the data of the literature concerning Tiopronine, a drug with a thiol function like D-penicillamine, in the treatment of rheumatoid arthritis. Two controlled trials versus placebo and two controlled trials versus D-penicillamine demonstrated the effectiveness of treatment and the identical action of 1 g of Tiopronine and 600 mg of D-penicillamine. The side effects of Tiopronine are very similar to those of D-penicillamine: essentially rash, toxiderma, aguestia, proteinuria, which resolve when treatment is stopped. Patients with a past history of side effects with D-penicillamine have an increased risk of developing side effects with Tiopronine, but this risk is not systematic, which constitutes the principal value of this drug.

[Algodystrophy and metabolic abnormalities].

The French Society of Rheumatology national study of reflex dystrophy revealed a serum glucose greater than 1.20 g/l in 9.09 p. cent of cases, a serum uric acid greater than 70 mg/l in 25 p. cent of men and greater than 60 mg/l in 14 p. cent of women. Serum cholesterol was normal in males, but higher than the mean + 2 sigma in 23 p. cent of females. Serum triglycerides were higher than m + 2 sigma in 55 p. cent of men and 56 p. cent of women. From a group of 80 patients, 54 (67.5 p. cent) had at least one of the three metabolic abnormalities and 49 (61.25 p. cent) were hypertriglyceridaemic. This hypertriglyceridaemia is the most frequent abnormality found. When hyperglycaemia or hyperuricaemia are present it is almost always in association with hypertriglyceridaemia. Hypertriglyceridaemia is more common in algoneurodystrophy of the lower limbs (54/78, 69 p. cent) than in algoneurodystrophy of the upper limbs (5/22, 22.7 p. cent). Algoneurodystrophy is more often primary, when it occurs in the lower limbs and post-traumatic when it occurs in the upper limbs. A prospective study comparing several parameters of lipid metabolism in 24 patients with algoneurodystrophy and 15 matched controls showed a significant drop in the HDL Chol/HDL P1 ratio and in the DHL - HDL Chol/TG ratio in patients with algoneurodystrophy. Serum insulin was comparable in the 2 groups. Lecithin cholesterol acyl transferase (LCAT), SGOT, SGPT and GGT were normal. The essential role of hypertriglyceridaemia in the genesis of the characteristic bony lesions of algoneurodystrophy is discussed.

[Role of pregnancy and related conditions on experimental arthritis of the rat (author's transl)].

Pregnancy in Rat induces, as in humans suffering from rheumatoid arthritis, a striking improvement of adjuvant arthritis. This improvement is not associated with an enhancement of corticosteronemia; it does not appear either in pseudo-pregnancy, or in experimental deciduoma. It could rather be related to an immune mechanism; an enhancement of T suppressor lymphocytes associated to a decrease of T helper lymphocyte activity in peripheral blood as suggested by a high response to ConA and low response PHA and PWM during arthritis plus pregnancy. The influence of hormonal factors on recirculation and/or activity of peripheral lymphocytes is not excluded.

Tiopronin (N-[2-mercaptopropionyl] glycin) in rheumatoid arthritis.

Two controlled trials have demonstrated that tiopronin, a new sulfhydryl compound, is active as a slow-acting antirheumatic drug in rheumatoid arthritis. One trial compared 10 patients receiving placebos and 20 receiving tiopronin, 1 gm/day; the second compared two groups of 16 patients who received either placebos or tiopronin, 1.5 gm/day. In addition, 80 patients (56 from the 2 trials plus 24 other patients) were followed up for a long period. Dropout rate for intolerance or inefficacy was comparable to that fund with D-penicillamine. Secondary toxic reactions resembled those of other sulfhydryl compounds.

Adjuvant arthritis in rat during pregnancy and lactation.

We have studied, in the female rat, the influence of pregnancy, lactation and pseudo-pregnancy on adjuvant arthritis. Pregnancy has a suppressive effect on the arthritis all the more marked as arthritis onset occurs during the third part of pregnancy. Pseudo-pregnancy with or without decidualization of the uterus does not modify the arthritis course; thus the corpus luteum and the decidual tissue cannot account for the observed improvement. Lactation has a beneficial effect that lasts until weaning. Amount of estradiol which insured approximate serum level of pregnant rats improves the polyarthritis. In the same conditions, progesterone remains inactive. Suppression by estradiol is observed in ovariectomized and intact females. Thus, in the female rat, pregnancy, lactation and physiological doses of estradiol improve adjuvant arthritis.

Effectiveness of levamisole in rheumatoid arthritis: Immune changes and long-term results.

After a double-blind trial of 4 months, 40 patients with RA were treated with 100 mg Levamisole. Clinical results were good or excellent in 50%. The immunological status is not a valuable criterion for the selection of patients apt to respond to Levamisole. A good correlation was found between clinical improvement, reduction of ESR, percentage of immunoblasts, rheumatoid factor titre and the enhancement of lymphoblastic response to polyclonal mitogens. The treatment maintenance rate for efficacy was much lower for Levamisole than for D-penicillamine.

[Tiopronine, new anti-rheumatic drug, has slow action in rheumatoid arthritis].

2 mercapto propionyl glycine (tiopronine) has, like D-penicillamine, a thiol radicle; it is a powerful chelating agent of heavy metals. This analogy suggests that it may be used in rheumatoid arthritis. A preliminary double blind study lasting four months comparing 1g./day in 20 patients and a placebo in 10 patients showed slight (non significant) efficacy concerning all parameters. An open study using 1.5 g. daily is being carried out in 32 patients, and we note a beneficial effect on the morning stiffness, the joint index, the functional index, the prehension strength, the E.S.R., and the joint swelling. The side effects are similar to those of D-penicillamine: loss of taste, proteinuria, mucous ulceration, which required stopping treatment. The therapeutic effect within 4 months and was maintained for 18 months in the 15 patients under treatment. A new double blind trial comparing placebo and tiopronine at a dose of 1.5 g. daily is in progress.

Xanthinuria : study of a large kindred with familial urolithiasis and gout.

We have carried out biochemical and clinical studies on a large family in which xanthinuria, xanthine lithiasis, uric acid lithiasis and/or gout were discovered. The analysis of its pedigree has shown that : a) the mode of transmission of xanthinuria is autosomal recessive; b) the occurence of xanthine urolithiasis is likely to be due to the association of a second genetic disorder.
