Seven patients had autoimmune progesterone dermatitis. The morphological findings illustrate the polymorphous nature of the disease in which urticaria, erythema multiforme, and dyshidrosiform lesions were seen. Recurrence of the eruption five to ten days prior to the menses with spontaneous resolution following the menses was present in all cases. Intradermal skin testing to progesterone was done to confirm the diagnosis. Six of the seven patients has a history of use of artificial progestational hormones prior to the beginning of their eruption. It is postulated that the artificial progesterones may have been the trigger for the development of their autosensitivity. Treatment with conjugated estrogens resulted in remission of the disease in five of the seven cases reported.

A double-blind study was carried out to investigate the possibility of therapeutic effect of levamisole on recurrent progenital herpes. One hundred and nine patients, including 53 females, entered the study, but only 75 completed. Levamisole, 50 mg three times daily for 3 days, was started at the first sign of recurrence. The study period consisted of 6 visits or 12 months, whichever came first. No statistical differences were observed between levamisole and placebo groups when comparing the duration of the lesion and the degree of pain, although less pain was observed among those on levamisole. The interval between attacks was increasingly prolonged in the levamisole-treated group, and reached a significant level at the sixth visit. However, analysis on the basis of mean cumulative number of days between attacks showed no significant differences throughout the study period. Because of occasional neutropenia and generalized urticaria, and because of the absence of clear-cut clinical improvement of statistical significance, levamisole was considered of limited benefit to patients with recurrent genital herpes infection.

A case is reported of a female patient who took 140 tablets of the antihistamine, mebhydrolin ('Fabahistin'), in one day for urticaria and experienced virtually no side effects. The urticaria cleared completely when her husband, who had a cardiac condition, died suddenly.

Recent evidence indicates that viral hepatitis is sometimes associated with the production of extrahepatic tissue injury. Hepatitis B virus (HBV) infection is most commonly incriminated but non-type B hepatitis may also be involved. Three types of syndromes have been recognized. First, a serum sickness-like prodrome consisting of skin eruptions, urticaria and polyarthralgias or arthritis may occur from one to six weeks prior to the onset of hepatitis in 15 to 20 per cent of patients and usually disappears by the time the patient becomes jaundiced. There is extensive evidence that circulating immune complexes are responsible for these symptoms. Second, about 30 to 40 per cent of patients with typical polyarteritis nodosa have persistent hepatitis B surface antigenemia (HBs Ag). Circulating immune complexes composed of HBs Ag, antibody, and complement have been demonstrated together with deposits of immune complexes at sites of vascular injury. Third, an immune complex type of glomerulonephritis may occur following hepatitis B virus infection, usually in association with chronic active hepatitis. Thus there is impressive evidence that hepatitis viruses, especially HBV, may produce a variety of extrahepatic manifestations in which the mechanism of pathogenesis involves an immunologic process rather than direct viral invasion and cytopathogenicity.

Two patients with typical Philadelphia chromosome positive chronic granulocytic leukaemia (CGL) developed an accelerated phase of the disease characterized by an increase white blood cell count and marked basophilia in the bone marrow and peripheral blood. Histamine levels were extremely high in both patients. Hyperhistaminaemia was manifested as wheezing, urticaria, diarrhoea, and pruritus in one patient and as peptic ulcer disease and peripheral oedema in both patients. In one case, gastric acid studies revealed a very high basal to stimulated ratio (BAO/MAO). Treatment with the investigational agent metiamide, an H2 receptor histamine antagonist, resulted in marked improvement in symptoms and reduction in gastric acid output. Extreme basophilia in CGL may be associated with hyperhistaminaemia, and manifestations of both the H1 and H2 type may occur.

A prospective study of the natural history of acute hepatitis B was performed in 38 patients. Fatigue started median 4 weeks, abdominal symptoms median 3 weeks and signs of cholestasis median 2.5 weeks before peak SGPT values were reached. Extrahepatic manifestations occurred throughout the prodromal stage, the presence of arthropathy, urticaria or skin rashes was not related to the biochemical severity of liver disease. The higher the the maximal values of serum bilirubin and/or the older the patient, the longer the period of bilirubin elevation; a maximal bilirubin elevation less than 20 X the upper limit of normal was associated with normalisation of serum bilirubin within 6 weeks. No such correlations were found between the height of serum glutamic pyruvic transaminase, alkaline phosphatase, thymol turbidity and cholesterol levels and the subsequent duration of their abnormality. The elevation of alkaline phosphatase as well as the abdominal complaints might partly be caused by gastro-intestinal involvement. Immobilisation before peak SGPT was attained was associated with normalisation of serum glutamic pyruvic transaminase levels within 8 weeks after peak levels. 37 patients recovered completely. In one HBs-antigenemia and slight SGPT elevation persisted. Long term follow up was possible in 33 patients for 4 to 7 years, median 5 years.

The changes in disease pattern in a Danish skin clinic during the period 1947 to 1977 is reported. The data rest upon comparisons from patient registrations taken with ten years interval. The study also comprises comparison of frequencies of positive patch tests between 1947 and 1977. The data show, that the disease pattern was far from stable. An increased frequency was registered in atopic dermatitis, allergic contact dermatitis, drug eruptions, urticaria, skin cancer, psoriasis and viral diseases. While reductions were found in all other infectious diseases, seborrheic dermatitis, and so called "non classified eczema". The changes are postulated to be of a multifactorial origine. Environment was supposed to be the main factor in regard to contact dermatitis and some infections and to be of great importance to skin cancer, while better therapeutic posibilities seem to have influenced the frequency of most of the remaining disease groups. Pronounced changes were also registered among the ten most commonly detected contact allergens. It is stated that preventive measures are extremely important within this area. The decrease in contact allergy to balsam of Peru is used as an example of the effects of good preventive medicine.

Serum immunoglobulins, complement and alpha 1-antitrypsin were assayed in forty-eight patients with chronic urticaria. Thirteen cases had chronic cold urticaria and thirty-two had chronic idiopathic urticaria. Elevated mean serum IgM was found in chronic cold urticaria. Seven patients had partial immunoglobulin deficiencies. IgE was elevated in sixteen cases of chronic idiopathic and in two with chronic cold urticaria. Eight patients had depressed serum total haemolytic complement activity. Low C3 and normal C4 serum protein concentrations in four cases suggested alternative complement pathway activation. Twenty of forty-six patients were atopic, although specific allergies responsible for the urticaria were not identified in any of them. alpha 1-antitrypsin levels were normal in all patients. The data suggest that the aetiology and pathogenesis of chronic urticarias in this study are heterogeneous. No evidence of abnormality of the protease inhibitor system in either chronic idiopathic or chronic cold urticaria was found.

Because previous studies have suggested an important link between eosinophilia and immunologic reactivity, we investigated various components of the immune system in a large number of patients with the idiopathic hypereosinophilic syndrome (HES) to elucidate a possible role for immunologic phenomena in the etiology and pathogenesis of this disease. Immunoglobulin G, A, or M levels were only rarely abnormal. However, in 8 of 21 (38%) patients with HES, IgE levels were markedly elevated suggesting an association of an IgE-mediated mechanism with eosinophilia in this subgroup. Severe dermatographism was present in three fourths of patients, and 2 patients with intermittently elevated histamine levels manifested an unusual form of immediate-pressure urticaria. Serum complement determinations showed elevated C4 and C3 levels in 27% and 77% of patients, respectively. Antigen-antibody complexlike material measured by C1q binding was elevated in the serum of 7 of 22 (32%) patients; this finding may relate to the known ability of eosinophils to avidly phagocytose antigen-antibody complexes. When compared with normals, lymphocytes from patients with HES showed a variety of abnormalities of lymphocyte surface receptors and lymphocyte function. Thus, patients with HES demonstrate a variety of immunologic abnormalities which may be related primarily or secondarily to the pathogenesis of this syndrome.
