[Significance of monitoring histamine serum levels, cryoglobulins and complement titers during cold tests in patients with cold allergy and Raynaud's phenomenon].

The aim of our investigations is to evaluate blood histamine, complement titer and cryoglobulins before and after cold stimulation (extremity water immersion test) in patients with cold urticaria and Raynaud phenomenon. In our investigations patients were put into five groups according to the following diagnoses: cold urticaria (40 patients), chronic urticaria (15 patients), Urticaria-Vasculitis Syndrome (15 patients), Raynauds Disease (16 patients), and Raynauds phenomenon (15 patients). The investigations demonstrated that the test was always positive in cold urticaria and that a high percentage of patients had a rise in blood histamine. This was found in 50% of the patients while cryoglobulins were found in one third of the patients. Consequently they can be grouped in secondary cold urticarias. A number of patients with chronic urticaria and Urticaria-Vasculitis Syndrome gave a positive history of cold sensitivity. Positive tests were accompanied by a rise in histamine, although (less frequently) there was a decrease in the complement titer and the occurence of cryoglobulins. Raynauds Disease was accompanied by a positive test in 94% of the patients, while patients with Raynauds Phenomenon (whose etiology was Thoracic Outlet Syndrome) had a negative test (60% of the patients). Significant changes were not found in the remaining groups. Positive tests were accompanied by abnormal values of cryoglobulins and of complement titer as well as an increase in histamine. The rise in histamine was not significant in Raynauds Phenomenon, while one patient had a decrease in the complement titer and the appearance of cryoglobulins.

[Clinico-laboratory characteristics of physical urticaria].

Physical urticarias represent a specific reaction of the skin, which is characterised by local erythema, edema and pruritus at the site where the physical stimulus has been applied. However, local changes can be associated with various systemic manifestations. Specific cutaneous reactions due to physical factors may be the first manifestation of a systemic and/or infectious disease, which should be taken into account as physical urticarias generally occur in young patients. In view of the above mentioned, as well as unpredictable course of the disease and relatively limited therapeutic effects, the etiology and pathogenesis of the physical urticarias are one of the most interesting fields of investigation in contemporary medicine.

[Effect of ranitidine on the pharmacokinetics of theophylline in patients with obstructive pulmonary disease].

Investigations were performed on 20 patients with mild and moderately severe forms of bronchiale asthma or chronic obstructive bronchitis. Theophylline for oral use (sustained release form) and Ranitidine (second generation H2-blocker) were used in the first group of patients (7 females and 3 males, average age 37.9). Dosage of theophylline from patients sera was monitored at 3, 6 and 12 hours, beginning with the initial morning dose. The second group of patients (9 females and 1 male, average age 46.3) were on Ranitidine therapy, along with 250 mg intravenous theophylline-ethylene-diamine. Fractionated dosage of theophylline was done within 12 hours. Pharmacokinetic parameters were calculated according to the concentration of theophylline in the sera of patients in the second group. Significant differences were not found by statistical analysis (T-test) in the pharmacokinetic parameters of theophylline although significantly higher concentrations of theophylline were found in the sera of patients in the first group. This indicated that there are individual differences on the metabolism of theophylline drugs with concomitant use of Ranitidine.

[Proteinuria in dermal vasculitis (incidence, degree and possible mechanisms of onset)].

The paper comprises 63 patients with diagnosed vasculitis of the skin who had abnormal findings in the urine. Thirteen of these patients had positive skin findings and abnormal findings in the urine, with concomitant attacks of dyspnea as seen in bronchial asthma. These patients account for 20% of the entire group, while there was an incidence of 37% of systemic manifestations. Skin findings: 45% had a maculopapular rash, 36% had urticarial findings, 13% had urticaria and angioedema and 6% had angioedema alone. Nonspecific biologic syndrome of evolution was statistically significant while no significant changes were found in the number of white blood cells and eosinophils. The degree of proteinuria ranged from 0.1 g/L to 1.16 g/L. Most patients with proteinuria above 0.25 g/L had microhematuria. Slightly over 50% of the patients had signs of complement activation by the alternative pathway, along with the presence of cryoglobulins. Increased histamine in the serum was found in over 50% of the patients although the values of histamine did not correlate with the degree of proteinuria. Proteinuria was not detected in patients with very high values of histamine (and without signs of vasculitis), which indicates that histamine itself responsible for changes in the glomeruli. There is a possibility that local tissue hyperhistaminemia is responsible for the increased permeability of the basal membrane of the glomeruli. According to the obtained results, the etiology of proteinuria and microhematuria should be pursued in the pathogenesis of vasculitis as signs of complement activation indicate. Other possible causes for proteinuria were excluded. The proteinuria was selective, benign according to its course and degree, occurred concomitantly with skin findings and was absent during remission of the disease.

[Laboratory study of patients with endemic nephropathy].

The introduction deals with the main characteristics of two representatives of high risk pregnancies: diabetes mellitus and EPH gestoses. Particular interest was shown in risks that may occur in pregnant diabetics, with which they must be acquainted. Some theories are given on the pathogenesis of EPH gestoses. The aim of our investigation was to determine the concentration at which immunoglobulins G, M and A pass in cord blood, amniotic fluid and urine, and whether there is a significant difference between control group and among pregnant diabetics or those with EPH gestoses. The investigation was performed by the nephelometric technique on the Immunochemistry Analyzer. Each group consisted of 20 women, with a total of 60. Immunoglobulins A, M and G were determined in the mothers' sera, cord blood or amniotic fluid. IgG was obtained in urine in measurable concentrations. A significant increase of IgG was found in the urine of pregnant diabetics. IgM was significantly increased in the sera of diabetic mothers. IgA was significantly increased in pregnant diabetics, while both high risk pregnancy groups had an increased IgA in cord blood. The values of IgA in amniotic fluid were decreased in the EPH gestoses group in comparison to the group of diabetics. The authors find these variations interesting and feel they should be followed in other high risk pregnancy groups.

[Total allergen-specific IgE antibodies in the serum and skin reactivity induced by a mixture of pollens in allergic individuals].

Skin puncture test is fast and precise method for revealing IgE-mediated allergen hypersensitivity. In the diagnosis of pollinosis and other atrophic diseases, expensive tests for revealing the allergen-specific IgE antibodies in the serum are frequently inaccessible. The subject of our investigation was how and if the skin test with mixture of pollen could replace the expensive in-vitro method in diagnostic procedure. In 41 patients with pollinosis were performed skin tests by the mixture of pollen of grass, weeds and trees (produced by Torlak Institute, Belgrade) and determined the concentration of overall and allergen-specific IgE serum (EIA, enzyme immuno-assay, Pharmacia Uppsala; RAST Phadesim, multidisk, Pharmacia). Obtained results pointed out that the sex of investigated subjects did not influence the size of skin reaction in case when the pollen mixture (grass, weed or trees) was used. With high significance rate was established that in skin puncture test, just the size of the reaction, defined by 5 mm papule or larger, indicated the hypersensitive person. We consider that this can be taken as the diagnostic criterion and replace in-vitro method for determination of allergen-specific IgE antibodies in serum. Also, overall IgE of serum positively correlated (p < 0.05) with the size of skin reaction only in the persons with extremely high concentrations (RAST class 4) allergen-specific IgE antibodies in serum.

[The effect of ranitidine on theophylline pharmacokinetics in patients with obstructive lung disease].

The study was performed in 20 patients with mild and moderately severe forms of bronchial asthma or chronic obstructive bronchitis. Theophylline for oral use (sustained release form) and ranitidine was used in the first group of patients (7 females and 3 males, mean years of age 37.9). Dosage of theophylline from patients' sera was monitored prior and at 3, 6, and 12 hours beginning with the initial morning dose. The second group of patients (9 females and 1 male, mean age 46.3 years) were on ranitidine therapy along with 250 mg intravenous theophylline-ethylene-diamine. Fractionated dosage of theophylline was made within 12 hours. Pharmacokinetic parameters were calculated according to the concentration of theophylline in the sera of patients in the second group. In the sera of patients in the first group significantly higher concentrations of theophylline were found at 3 and 6 hour of the initial morning dose (p less than 0.05). In the second group a significant difference was not registered for the assessed pharmacokinetic parameters. This investigation indicates that there are individual differences of the metabolism of theophylline drugs with concommitant use of ranitidine.
