[Bone scintigraphy in psoriasis (author's transl)].

Since 1973 bone scintigraphy using 99mTc-phosphate-complexes was carried out in 382 patients with psoriasis. For comparison with the results of nuclear medicine, roentgenologic and clinical findings a group of 121 patients with psoriasis aged between 11 and 74 years was compared to a group of 42 patients aged between 20 and 49 years without roentgenologic and clinical signs of psoriatic arthritis. We found by means of isotope investigation that an essentially greater part of the bones adjacent to the joints was involved than was expected according to X-ray and clinical findings. In addition, in 205 patients with psoriasis whole-body scintigraphy, using 99mTc-MDP, was carried out sine 1977/78. In 17 patients we found an increased accumulation of activity in the region of extraarticular structures of the skull as well as of the skeletal thorax. According to these results we conclude that in addition to the clinically and roentgenologically defined psoriatic arthritis in patients with psoriasis and osteopathy may exist, which can only be demonstrated by skeletal scintigraphy and which is localized in bones adjacent to the joints but can also be demonstrated in the region of extraarticular bones.

[Zinc deficiency syndrome during long-term parenteral nutrition in a patient with Crohn's disease and cirrhosis of the liver. Casuistry and zinc-pharmacokinetic (author's transl)].

A 29 year old patient with Crohn's disease and posthepatitic HBsAg-positive cirrhosis developed zinc deficiency in the course of complete parenteral nutrition. Zinc deficiency was proven by a low plasma zinc level of 12 microgram/dl. The daily input of zinc was 0.5 mg as calculated from the zinc concentration of infusion solutions used in parenteral nutrition during 3 1/2 months of treatment. The clinical picutre was that of acrodermatitis enteropathica. Cirrhosis of the liver and Crohn's disease were contributory causes of zinc deficiency. 6 bolus injections of 12-36 mg of zinc (total amount 144 mg) were given during 13 days. The plasma zinc level increased to 60-80 microgram/dl. 52% of the total amount of zinc injected were excreted by urine. The plasma half-life times of zinc were independent from basic zinc concentrations and averaged 1.55 +/- 0.22 h. It is concluded that severe signs of zinc deficiency will develop during parenteral nutrition in the presence of conditions leading to a negative zinc balance. In the case of long-term complete parenteral nutrition zinc should be substituted from the beginning of the treatment on.

Immunological studies in patients with alopecia areata.

Cellular and humoral immune parameters were studied in 10 patients with alopecia areata totalis and universalis. Trends to low normal immunoglobulins levels and in vitro lymphocyte transformation to concanavalin A were observed. Serum CH-50 levels and skin test responses to mumps, candida, trichophytin and dinitrochlorobenzene (DNCB) not found in vitro. 1 patient with alopecia universalis of 33 years duration developed hair at the site of DNCB skin testing. The findings point to rather subtle immune defects in patients with this disease.

The absorption of benzoyl peroxide from leg ulcers.

Absorption and clinical efficacy of a preparation containing 20% benzoyl peroxide were studied in 20 patients with leg ulcers of varying etiology. Benzoic acid formed from benzoyl peroxide on penetration through the skin cannot be demonstrated in the plasma until three days after commencing application at the earliest. This indicates a building up of deposits of benzoyl peroxide in the skin. The plasma benzoic acid levels in all patients amounted to less than 5 mumol/l and is therefore toxicologically inoffensive. Clinically, the known therapeutic effects of benzoyl peroxide were confirmed. Neither sensitization nor allergic reactions were found in the 20 patients taking part in this study.

[Studies on percutaneous absorption of flumetasone pivalate and salicylic acid from a corticoid combination for topical use (author's transl)].

The combination of 0.02% flumetasone pivalate and 1% salicylic acid in a water-alcohol solution (Locasalen) is a novel therapeutic for topical treatment of the hairy scalp and also for the cosmetically acceptable treatment of other skin areas, that is, exposed skin. An investigation was carried out in 6 patients with psoriasis capitis and 6 control subjects in order to determine whether the use of Locasalen Tincture on the hairy scalp leads to percutaneous absorption of the corticosteroid and the salicylic acid. In the patients with psoriasis a few slight transient changes in biochemical-endocrinological parameters were observed, but not in the control subjects. However, these changes remained within the normal, non-pathological range so that they are of no clinical consequence. Percutaneous absorption of salicylic acid was not observed in either patient group.

[HLA antigen frequencies in patients with progressive systemic sclerosis and morphea (author's transl)].

Forty three patients with progressive systemic sclerosis and 24 patients with morphea are typed for 30 antigens of the HLA-A and B series. There is an increase of the frequency of HLA-B8 in patients with progressive systemic sclerosis (37% vs. 20% in controls: P less than 0.001, Pcorr. = n.s.). The increase of the HLA-B8 frequency seems to be most pronounced in patients with a diffuse form of progressive systemic sclerosis. 4 out of 5 patients are HLA-B8 positive (P = 0.00672). In patients with acrosclerosis is HLA-B8 only slightly increased (32%), but the increase is greater in male patients (44%) and in patients with an early onset of the disease (36%). With the exception of HLA-A1 there is no deviation of the frequencies of any other HLA antigen tested, especially not of HLA-Aw24. The number of patients with morphea is to small for statistical evaluation.

[Bone findings in psoriasis].

Three female patients out of 40 psoriatics examined with scintigraphical methods (Tc-diphosphonate) were found to have a diffuse and circumscribed pathological increase of nuclide at the skull. These abarticular signes of proliferation at the bone-area indicate an early affection of skeleton of patients with psoriasis which is similar to the joint-scan that is mostly obtained in positive bone-scan.

[Treatment of arthritic psoriasis with Demoplas Clinical and scintigraphic study in 10 patients (author's transl)].

Clinical, X-ray, and scintigraphic (6mCi 99mtechnetium pertechnetate, 4mCi 99mtechnetium pyrophosphate) tests for joint involvement were conducted on 11 inpatients with psoriasis (4 female, 7 male), 6 of them cases of what is conventionally termed psoriatic arthropathy. These tests were performed both before and after a 12-day period of therapy with daily 4 x 1 coated tablets of Demoplas containing 150 mg phenylbutazone Scintigraphic tests showed that pathological radionuclide concentrations were present in at least one joint or group of joints in 10 out of 11 patients. Following therapy the previously pathological scintigraphic findings had stabilized completely in 4 patients and partially in 3 patients, but had not stabilized in 3 patients. The results of therapy with Demoplas as demonstrated by joint scintigraphy were thus good to satisfactory in 7 patients and unsatisfactory in 3 patients- possibly owing to the short duration of therapy. The improvement in scintigraphic results testifies to the therapeutic action of phenylbutazone on arthritic psoriasis. This can also be regarded as additional proof that psoriatic joint involvement is of an inflammatory and proliferative nature.
