Cytostatic treatment of glomerular diseases. III. A double-blind cross-over study of the effect of cyclophosphamide report from a copenhagen study group of renal diseases.

Fifty patients with renal glomerular diseases entered a double-blind cross-over study on the effect of cyclophosphamide; 38 had received neither corticosteroids nor cytostatic drugs before joining the study. Cyclophosphamide was given for 4 months in doses decreasing from 3 to 1.5 mg/kg b.wt. Cyclophosphamide caused a 46% decrease in the 24-hour excretion of urinary protein and a decrease in serum creatinine within the normal range. Albumin, transferrin and IgA in urine, as well as albumin clearance and the sieving coefficient of albumin, changed parallel to the total urinary protein. The initial values of proteinuria and serum complement were of prognostic significance for the effect of cyclophosphamide in serum creatinine. We were unable to demonstrate a prognostic significance for the variables: clinical diagnosis, renal histology, arterial BP, initial values of serum creatinine and IgG, IgA and IgM in serum and urine. ESR appeared to be the most reliable acute phase reactant. No differences were found between the changes in renal histology during cyclophosphamide or placebo.

Beclomethasone dipropionate aerosol treatment of hay fever. A dose-response investigation.

In a controlled, double-blind study 20 children and adults, suffering from summer hay fever, were treated intranasally with a daily dose of 200 mug, 300 mug or 400 mug beclomethasone dipropionate (Beconase, Becotide Nasal) or with placebo for 2 weeks during the hay fever season. No beneficial effect of the placebo treatment was observed. In patients treated with 200 mug and 300 mug beclomethasone dipropionate a day there was a moderate decrease in nasal symptom scores and in use of antihistamine tablets. As the results indicated 400 mug a day to have the most pronounced effect on nasal symptoms, this dosage is recommended for children as well as adults suffering from summer hay fever.

Deposits of immunoglobulins and complement C3 in clinically normal skin of patients with lupus erythematosus.

Deposits of immunoglobulins and/or complement C3 were found in two-thirds of biopsies from clinically normal skin of 64 patients with systemic lupus erythematosus, as judged by well defined criteria. The incidence of deposits in clinically normal skin was identical in patients with and without clinical skin lesions. IgM was found more frequently in the deposits (88%) than was IgG (36%) but equally frequently in involved and uninvolved skin, whereas C3 was found more often in patients with skin lesions (59% in involved skin, 36% in uninvolved skin) than in patients without skin lesions (14%). The occurrence of IgG and IgA was less frequent than that of C3 but the distribution was similar to that of C3. In normal skin of 20 patients with chronic discoid LE, deposits were found in one. Deposits were found in the skin of one-third of patients with nuclear antibodies in their sera and symptoms compatible with SLE but with a score of symptoms too low to meet the criteria.

DNA-antibodies in sera from patients with systemic lupus erythematosus.

DNA-antibody determinations using the Farr technique and LE cell tests were performed on single serum samples from 55 patients with SLE according to well defined criteria. It was found that the DNA-antibody test was just as sensitive as the LE cell test, and studies of sera from patients with questionable SLE, discoid LE, other connective-tissue diseases, psoriasis, and from healthy persons, indicated that the DNA-antibody test is highly specific for SLE. Neither the DNA-antibody test nor the LE cell test could discriminate between SLE patients with active and inactive disease as estimated by clinical criteria or by the serum concentrations of complement C3 and C4.

Anti-basement membrane antibodies in sera from patients without bullous pemphigoid.

Sera from 208 individuals were examined for antibasement membrane (anti-BM) antibodies by means of an indirect immunofluorescence technique. In sera from patients with bullous pemphigoid 19 of 25 had anti-BM antibodies in titres varying from 80 to 32 000. In 2 of 42 sera from patients with psoriasis, anti-BM antibodies were demonstrated (titres 40-640). Of 58 sera from patients with leg ulcers, antibodies were found in 4 (titres 40-320). Antibodies were found in 2 of 43 patients with cardio-vascular disease (titre 80) and in 1 of 40 control persons (titre 40). Serum from one of the patients with leg ulcers caused a punctate staining pattern unlike the tubular pattern seen in all other positive sera.

Deposits of immunoglobulins and complement in the dermoepidermal junction of patients with anaphylactoid purpura.

Skin biopsies from 3 patients with anaphylactoid purpura examined by an immunofluorescence technique revealed deposits of immunoglobulins, complement C3, and fibrinogen in the dermo-epidermal junction and in vessel walls of clinically involved as well as uninvolved skin. The deposits in the dermo-epidermal junction are similar to those seen in the skin of patients with systemic lupus erythematosus.
