A case of a 44 year old woman with antrum gastritis and H. pylori infection was reported. After unsuccessful treatment of the disorder with bismuth and tinidazole, an auto-vaccine was prepared from the bacterium in order to eliminate the infection. After the first injection of the vaccine a generalised urticaria was observed. In the development of the skin eruptions a type I, and a type IV allergic reaction could be demonstrated using the H. pylori specific RAST-test and leukocyte migration inhibition respectively. After eradication of the bacterium by amoxycillin treatment, the clinical signs of both the gastrointestinal and allergic diseases disappeared.

The most common adverse effects of nonsteroidal anti-inflammatory drugs are gastritis, peptic ulceration, and depression of renal function, all of which result primarily from prostaglandin inhibition. The types of side effects observed with diclofenac are similar to those of other nonsteroidal anti-inflammatory drugs and are unavoidable given that the drugs are prostaglandin inhibitors. However, the incidences of such side effects may be lower with diclofenac than with some of the other nonsteroidal anti-inflammatory drugs. Worldwide experience with diclofenac exceeds 7.6 million patient-years, which should provide estimates of the frequency of very rare adverse reactions. The latter include blood dyscrasias, erythema multiforme, hepatitis, and others, such as aseptic meningitis, anaphylaxis, and urticaria. Moreover, some nonsteroidal anti-inflammatory drugs appear to have unique side-effect profiles. Examples include a higher incidence of ulceration and erythema multiforme with piroxicam, and acute pancreatitis, in rare instances, with sulindac. From a careful survey of the world's accumulated literature and reports to CIBA-GEIGY, diclofenac does not appear to have any unusual adverse reactions.

Excluding the most frequent kinds of problems seen with the nonsteroidal antiinflammatory drugs (NSAID)--gastritis, peptic ulceration and renal effects--published reports indicate that these drugs may cause a wide variety of rare adverse reactions. The most serious of these are hypersensitivity reactions: blood dyscrasias (aplastic anemia, thrombocytopenia, agranulocytosis, hemolytic anemia), erythema multiforme and hepatitis. Aseptic meningitis and anaphylactoid reactions may strike patients with underlying immunologic abnormalities; urticaria, bronchospasm and proctocolitis may affect aspirin-sensitive patients. Other unusual reactions include several kinds of bullous dermatitis, febrile reactions, pneumonitis, esophageal ulceration, parotitis, pancreatitis and neurological or psychological effects.

A random group of 37 patients with chronic recurrent urticaria, 26 female and 11 male, was subjected to multidimensional personality tests (Freiburg personality inventory, FPI, Freiburg aggression test, FAF) whereas, deviating from establishing standards, introversion, nervousness, psychosomatic disturbance were more pronounced in the urticaria group, the following traits in deviation from normal standards were not noted: depression, irritability, sociability, emotional instability, composure. Nevertheless, this group appeared to be less communicative, more inhibited, compliant, and less dominant and aggressive. Neither did they show signs of socially accepted expression of negative and annoyed emotions nor socially desirable signs of assertiveness. A high rate of coincidence with other psychosomatic disorders such as frequent headache (18/37), chronic gastritis (19 of 37) and ulcus duodeni (5 of 37) and migraineous headache (6 of 37) was also found in this group. In all cases explorable latent conflictive situations (frequent ambivalence) and negative childhood experience are further indicative of psychosomatic diseases.

A questionnaire was used from 1972-1978 for 330 consecutive patients with recurrent urticaria of 3 months to 40 years duration. Fifty men and fifty women had only urticaria. The rest had both urticaria and angio-oedema and most of them were women between 24 and 38 years of age. Urticarial attacks were less frequent during the daytime. A personal history of rhinitis, asthma or atopic dermatitis was recorded in more than one-third. Nasal polyps, migraine and arthralgia were found in 6-7% of the patients. Severe psychiatric problems were mentioned by 16%. Abdominal problems, mainly gastritis, were described by 44%. A history of side effects from drugs was found in 32% of the patients. Food was mentioned as a factor worsening the weals by 30% and drinks by 18%. Fruits, vegetables and nuts were the most common. Despite all cases with physical urticaria having been excluded, physical factors such as exercise were considered by 20% to make the urticaria worse. Provocation tests with various food additives such as azo dyes, benzoates, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA) sorbic acid, quinoline yellow, carotene, canthaxanthine, annatto and nitrite revealed one or more positive reactions in one-third of the patients, one-third showed negative provocation tests and, in the rest, one or several tests were questionable. Routine history of other diseases. The fibrin microclot generation test which test which indicates the presence of circulating endotoxins was positive in 24%.

At some time in their lives one in a five persons is affected by urticaria and/or angioedema. The cause of urticaria may never be found in up to one quarter of patients with acute urticaria and in up to 90-95% with chronic urticaria. In this study we present results of our compounded approach (clinical follow up, laboratory findings, allergological testing) to patients with chronic urticaria and autoimmune diseases that progressed into chronic urticaria or started before the onset of the chronic urticaria. Our first case was a 56 year old woman with a 10 month history of chronic urticaria, angioedema and chronic gastritis before the diagnoses of insulin dependent Diabetes mellitus and Hypothyreoidismus primarius were established. Allergological testing reveals specific clinical significant immediate reaction to Balsam Peru. After adequate substitutional therapy was advocated and with specific clinical avoidance of offended allergen, remission was obtained. The second case was a 46 year old female suffering from chronic urticaria (with clinical features of urticaria like vasculitis) associated with hypocomplementemia (particularly C4 depressed) with negative antinuclear antibodies but positive circulating immune complexes after a 2 year follow up the patient developed Systemic lupus erythematosus. The third case was a 63 year old woman who developed chronic urticaria 3 years after total thyroidectomy, with pathological finding of Thyroiditis lymphocytaria-Hashimoto; after the allergological testing, positive lymphocyte transformation test revealed allergical sensitization to Vobenol was substituted with Thyvoral, complete remission was obtained.

Helicobacter pylori, a microaerophilic gram-negative bacterium, is the major cause of gastritis, plays a key role in the etiology of peptic ulcer and is a risk factor for gastric cancer. Although 50% of the population is affected, dermatologist seem to be unaware of the impact H. pylori may have on cutaneous pathology. Among skin diseases, H. pylori has been related so far only with chronic urticaria and rosacea. In rosacea, histology of the stomach mucosa revealed tht 84% of 31 patients were H. pylori positive. Twenty percent of them were serologically negative, but, overall, 100% of the 20 patients with both histology and serology were H. pylori positive with either test. The consistency between clinical success with metronidazole and abatement of H. pylori isolates and serology after treatment was an additional evidence suggesting an etiologic relationship between rosacea and H. pylori infection. Rosacea has often been linked with gastrointestinal disturbances. H. pylori, therefore, may link them to the well-known beneficial activity of metronidazole on rosacea lesions. The role of H. pylori is more probable in erythrotic rosacea than in its papulopustular and granulomatous stages. As in Bacillus subtilis intoxication, a flush-inducing toxin cannot be excluded. Despite the difficulty to find patients accepting bioptic gastroscopies, large case-control studies should be done before a causal relationship with urticaria and rosacea is firmly established.

Helicobacter pylori, the most important cause of gastritis and peptic ulcer, recently has been associated with several extradigestive diseases. The aim of this study was to assess the prevalence of Helicobacter pylori infection and the effects of bacterium eradication in 42 consecutive patients affected by idiopathic chronic urticaria. Helicobacter pylori was assessed by [13C]urea breath test. Amoxicillin, clarithromycin, and lansoprazole were given to infected patients for seven days. Urticaria and gastrointestinal symptoms were assessed on enrollment and after eradication. Fifty-five percent of patients proved to be infected by Helicobacter pylori. Prevalence of gastrointestinal symptoms did not differ between infected and uninfected patients. Eighty-eight percent of infected patients in whom the bacterium was eradicated after therapy showed a total or partial remission of urticaria symptoms. Conversely, symptoms remained unchanged in all uninfected patients. In conclusion, Helicobacter pylori affects a high percentage of patients with idiopathic chronic urticaria; however, typical gastrointestinal symptoms do not identify infection status. Bacterium eradication is associated with a remission of urticaria symptoms, suggesting a possible role of Helicobacter pylori in the pathogenesis of this skin disorder.

There are several types of immunological tests available for the diagnosis and management of Helicobacter pylori infection. Most commercially available serological kits use the enzyme linked immunosorbent assay (ELISA) test format. Originally the kits used crude antigen preparations although many of the newer kits use a more purified antigen preparation, with often increased specificity but lower sensitivity. Near patient test kits are based either on latex agglutination or immunochromatography. Generally they have low sensitivities compared with laboratory tests. Western blotting, ELISA, and recombinant immunoblot assays (RIBA) have also been developed into commercially available kits and can be used to indicate the presence of specific virulence markers. An antigen detection kit has been developed for the detection of Helicobacter pylori in faeces. Immunological reagents have also been combined with other diagnostic modalities to develop immunohistochemical stains and DNA immunoassays. Helicobacter pylori is now recognised as the cause of gastritis and most cases of peptic ulcer disease (PUD); its long term carriage increases the risk of gastric adenocarcinoma sixfold and it is designated as a class I carcinogen. H pylori has also been implicated as a cause of gastric mucosa associated lymphoid tissue lymphomas. Its relation to non-ulcer dyspepsia remains controversial. Additionally, long term carriage of the organism may be associated with short stature in young girls and, in the general population, as a possible risk factor for the development of vasospastic disorders and possibly skin immunopathology such as urticaria. With the recognition of H pylori as an important human pathogen, it has become one of the growing number of organisms to have its complete genome sequence mapped. Serology is an important method of determining colonisation status and can be used for diagnosis, as a screening procedure, or to follow the efficacy of eradication regimens. Most serological assays are in the ELISA format although some are based on the latex agglutination reaction. These latter are used principally as near patient assays. Most assays detect IgG in serum although some detect serum IgA. More recently developed assays detect IgA in saliva and the production of affinity purified antibodies has led to the development of an antigen detection assay for faecal specimens. Serological reagents have also been used in immunocytochemistry and to speed up the detection of amplified products of the polymerase chain reaction (PCR)-DNA immunoassays.

The etiology of chronic urticaria is largely unknown. The role of Helicobacter pylori infection, which is the most important cause of gastritis and peptic ulcer, is not clear in the pathophysiology of chronic urticaria. In this study, we aimed to define the impact of H. pylori on chronic urticaria. Thirty-eight patients who had chronic urticaria of unknown origin and dyspepsia were included in the study. In all patients, standard laboratory tests for detection of urticaria etiology were performed. Mean urticaria symptom scores of patients were carried out. All patients underwent upper gastrointestinal endoscopy. The presence of H. pylori was investigated using urease testing and histopathology. Duodenal fluid aspirated during upper endoscopy was examined for the presence of Giardia lamblia. H. pylori infection was detected in 29 patients. After successful eradication of H. pylori infection, the mean symptom score of patients did not change significantly (2.6 +/- 0.6 vs., 2.4 +/- 0.8). Only one patient had a total disappearance of urticaria symptoms. Out of 38 patients, only one had G. lamblia infection. The results of our study suggest that there is no association between H. pylori infection and chronic urticaria.
