Urticaria and bacterial infections

2014

The association between urticaria and infectious diseases has been discussed for >100 years. However, a causal relationship with underlying or precipitating infection is difficult to establish. The purpose of this work was to perform a systematic analysis of the published cases of urticaria associated with bacterial infections. We give an umbrella breakdown of up-to-date systematic reviews and other important publications on the complex association of urticaria and bacterial infections. We did a Medline search, for English language articles published until January 2014, using the key words "urticaria" and "bacteria/bacterial disease"; a second analysis was performed in groups of bacteria an…

A Comparative Study on Nickel Binding to Hpn-like Polypeptides from Two Helicobacter pylori Strains

2021

Combined potentiometric titration and isothermal titration calorimetry (ITC) methods were used to study the interactions of nickel(II) ions with the N-terminal fragments and histidine-rich fragments of Hpn-like protein from two Helicobacter pylori strains (11637 and 26695). The ITC measurements were performed at various temperatures and buffers in order to extract proton-independent reaction enthalpies of nickel binding to each of the studied protein fragments. We bring up the problem of ITC results of nickel binding to the Hpn-like protein being not always compatible with those from potentiometry and MS regarding the stoichiometry and affinity. The roles of the ATCUN motif and multiple His…

Multicentric randomised study ofHelicobacter pylorieradication and pepsinogen testing for prevention of gastric cancer mortality: the GISTAR study

2017

IntroductionPopulation-based eradication ofHelicobacter pylorihas been suggested to be cost-effective and is recommended by international guidelines. However, the potential adverse effects of widespread antibiotic use that this would entail have not been sufficiently studied. An alternative way to decrease gastric cancer mortality is by non-invasive search for precancerous lesions, in particular gastric atrophy; pepsinogen tests are the best currently available alternative. The primary objective of GISTAR is to determine whetherH pylorieradication combined with pepsinogen testing reduces mortality from gastric cancer among 40–64-year-old individuals. The secondary objectives include evaluat…

Helicobacter pylori and Barrett’s esophagus: a protective factor or a real cause?

2017

Nothwithstanding the definite aethiopathogenetic path of certain diseases, the relationship between Helicobacter Pylori (H. Pylori) and barrett's esophagus (BE), a condition that increases the risk for dysplasia and consequently adenocarcinoma of the distal esophagus and esophagogastric junction, remains uncertain. this paper reviews the current scientific literature with emphasis on the protective correlation between H. Pylori infection and BE, and demonstrates that a causal relathionship has not been disproved with certainty. Furthermore, H. Pylori infection could pose a risk for the onset of gastroesophageal reflux disease (GERD), which could in turn trigger BE, a precancerous lesion and…

Role and clinical importance of Helicobacter pylori infection in hemodialysis patients

2008

Dyspepsia is an extrarenal symptom frequently found in hemodialysed patients; it is due to chronic renal failure, and uremic gastritis is a specific associated condition in chronic renal failure (CRF). On the other hand, in the general population, Helicobacter pylori infection is an important dyspepsia-related risk factor; its close connections with gastro-duodenal pathology are already known, above all the peptic disease in a really exclusive way. By observation of a dyalitic group of patients, opportunely matched with a no CRF group, we evaluated CRF-associated uremia and Helicobacter pylori infection which could eventually interact causing symptoms and lesions. A statistical analysis of …

Upper gastrointestinal diseases correlated to helicobacter pylori infection: Comparison between uremic and non-uremic patients. Review of the literat…

2012

Helicobacter Pylori is the first cause of infection of the upper gastrointestinal tract in hemodyalisis patients. The hemodialytic treatment can lead to spontaneous eradication of this bacteria, but the frequency of pathological involving the upper gastrointestinal tract is still higher in these patients compared to hemodialysis patients negative for the infection and normal patients. In consideration of virulence and pathogenicity of helicobacter pylori infection, there is the strong recommendation for eradication therapy in uremic patients, that it has been demonstrated to reduce the incidence of benign and malignant of the upeer gastrointestinal tract.

No invasive methodology to produce a probiotic low humid apple snack with potential effect against Helicobacter pylori

2012

Abstract A probiotic low humid apple snack with potential effect against the infection caused by Helicobacter pylori has been developed from apple (cv. Granny Smith) and mandarin juice with a high microbial content of Lactobacillus salivarius spp . salivarius , by vacuum impregnation and hot air drying techniques. The moisture content reached in the final product (0.144 ± 0.012  g water · g sample - 1 ) ensured stability, and although the drying process affected the microbial content, the concentration in the final product (9.486 ± 0.013) × 10 7  CFU  g dry sample - 1 ) was sufficient to confirm that with this procedure it is possible to obtain a stable probiotic fruit with a low moisture c…

Ģenētisko faktoru asociācija ar Helicobacter pylori seroloģisko prevalenci Latvijas populācijā

2015

Baktērija Helicobacter pylori (HP) izraisa hronisku gastrītu, peptisko čūlu, kuņģa adenokarcinomu, MALT limfomu, un tās radītā infekcija ir visplašāk izplatītā cilvēku infekcija. Populācijas pētījumā atklāts, ka HP prevalence Latvijā ir gandrīz 80%, kas ir augsta. Pamatojoties uz Nīderlandes GWAS pētījumu rezultātiem, tika izvēlēti 5 gēni un to polimorfismi- PCLO (rs147900026), TLR10 (rs12233670), FCGR3A (rs147174426), TLE4 (rs138776142), ADRA1D (rs6107461)- lai noskaidrotu, vai šie polimorfismi asociējas ar HP seroprevalenci un kuņģa gļotādas atrofiju Latvijas populācijā. Rezultāti: PCLO gēna rs147900026 G alēle samazina HP infekcijas risku, FCGR3A gēna rs147174426 T alēle tiek būtiski aso…
