Săsăran MO, Mărginean CO, Koller AM. Impact of Helicobacter pylori Infection upon the Evolution and Outcome of Pediatric Immune Thrombocytopenic Purpura: A Comprehensive Review. Diagnostics (Basel) 2023; 13:3205. [PMID: 37892026 PMCID: PMC10606204 DOI: 10.3390/diagnostics13203205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/08/2023] [Accepted: 10/12/2023] [Indexed: 10/29/2023] Open
Abstract
In adults with immune thrombocytopenic purpura (ITP), the identification of H. pylori infection and its subsequent eradication proved to aid platelet recovery. Similar findings, at a smaller scale, were allegedly reported by some pediatric studies. This review's objective was to establish the influence of H. pylori infection and its eradication upon platelet count and recovery in pediatric ITP. Three databases, namely Pubmed, Scopus and Web of Science, were searched for pediatric studies which investigated a link between H. pylori infection and thrombocytopenia. The search results retrieved a number of 21 articles which complied to the inclusion and exclusion criteria. Some studies report lower platelet values among children with ITP and documented H. pylori infection, as well as an improve in platelet numbers after H. pylori treatment. However, results are controversial, as multiple authors failed to identify a higher prevalence of H. pylori among children with ITP or a lack of significant change in therapeutic outcome with the addition of an eradication regimen to standard treatment. The main limitations of current pediatric studies remain the small study samples and the short follow-up periods of the included subjects. Hence, the long-term impact of H. pylori in children with ITP is still uncertain.

Abstract
Background Diagnosis of gastric ulcers by methods other than gastroscopy in dogs has been problematic for many years and biomarkers such as serum gastrin (SG) concentrations have been introduced as a noninvasive way to evaluate gastric diseases. Objectives To determine the time course changes in hematology, SG concentrations, and gastroscopic images of meloxicam‐induced gastric ulceration in dogs and identify a relationship between SG and gastroscopic image analysis in a clinical setting. Animals Fifteen crossbreed dogs. Methods Two groups: control (n = 5) and meloxicam‐treated (n = 10). The meloxicam‐treated group received meloxicam 0.2 mg/kg PO for 15 days. Clinical signs, hematology, SG, and image analysis (PI, pixel intensity; ID, integrated density; RA, relative area; and UI, ulcer index) of the gastroscopic examination were evaluated across time (T5, time 5 day; T10, time 10 day; and T15, time 15 day). Results Significant changes were observed among 3 time points and between the 2 groups in terms of SG, hematology, and gastroscopic image analysis. In the meloxicam‐treated group, decreases in hemoglobin concentration, red blood cell count and packed cell volume at T10 and T15 (P = .0001) were observed, whereas SG, ID, and UI increased over time (P < .0001). The PI decreased significantly (P = .0001) in the meloxicam‐treated group compared to controls. Significant correlations were found between SG and PI, and ID and ulcer area (r = −0.89, 0.81, 0.64), respectively. Conclusion and Clinical Importance Gastroscopy is the gold standard for early descriptive diagnosis of gastric ulcerations in dogs, and SG is a good indicator for meloxicam‐induced gastric ulcers in dogs and can predict the gastroscopic score of the lesion.

Abstract
Helicobacter pylori causes one of the most common infections in human populations. The role of this bacterium in chronic gastritis, gastric ulcer, gastric cancer, as well as extra-digestive diseases such as ischemic heart disease and chronic obstructive pulmonary diseases, is well known. Prevention and control of these diseases can occur by early diagnosis and eradication of H. pylori infection. At present, different methods have been established to detect H. pylori infection. The biopsy-based tests, which are known as invasive methods, such as rapid urease test and histology, have the highest specificity among the others. Similarly, culture of biopsy samples is used for diagnosis of H. pylori infection. It has a high specificity value, and also allows us to perform antibiotic sensitivity testing. On the contrary, polymerase chain reaction and other molecular methods have good sensitivity and specificity, and can be used for detection of H. pylori infection, its virulence factors, and eradication success after treatment. While serological tests are more appropriate for epidemiological studies, their main weakness for clinical use is low specificity. Overall, specificity and sensitivity, cost, usefulness, and limitation of tests should be considered for selection of detection methods of H. pylori in each country.

Abstract
BACKGROUND/AIM The aim of this study was to investigate the role of the platelet-to-lymphocyte ratio (PLR)-neutrophil-to-lymphocyte ratio (NLR) combination, in the prediction of the presence of Helicobacter pylori (HP) and its associated complications in the gastrointestinal system. PATIENTS AND METHODS In all, 1289 patients who underwent esophagogastroduodenoscopy and biopsy for HP were included in the study. RESULTS The ratio of patients with moderate and severe chronic gastritis was higher in HP (+) group than HP (-) group. The ratio of patients with levels 1-3 atrophy and intestinal metaplasia was higher in HP (+) group. Compared with HP (-) group, HP (+) had higher PLR and NLR levels. The ratio of HP (+) patients was higher in high-risk group compared with low- and medium-risk groups. HP invasion stage, the intestinal metaplasia level, and the ratio of patients with atrophy level "3" were higher in high-risk group compared with low- and medium-risk groups. Regression analysis showed that the PLR-NLR combination was an independent risk factor for both HP presence and moderate and severe chronic gastritis. CONCLUSION We found the PLR-NLR combination to be a good predictor of HP presence and gastrointestinal complications associated with HP.

Abstract
To evaluate the influence of Helicobacter pylori and sex difference on peripheral platelet counts, dyspeptic patients without immunohaematologic disorders were evaluated. H. pylori infection was verified with the rapid urease test and serum anti-H. pylori IgG antibody. Platelet counts were analysed with a reference to H. pylori infection and sex difference. Among H. pylori-eradicated patients, changes in platelet counts were separately evaluated. Totally, 655 patients were enrolled: 340 patients were infected with H. pylori and 178 patients received eradication therapy, with a success rate of 88.2% (157/178). Females with H. pylori infection definitely manifested elevated platelet counts (infected vs. uninfected 244 ± 57 vs. 219 ± 54 × 10(9)/l; p < 0.0001). H. pylori eradication reduced peripheral platelets by 8 weeks, 5-6 months, 1, 2 and ≥3 years after eradication in females from 248 ± 54 to 237 ± 49, 237 ± 54, 229 ± 48, 238 ± 61 and 232 ± 50 × 10(9)/l (p = 0.0003, 0.0182, 0.0041, 0.0398 and 0.0289), respectively. In males, the reduction was verified by 8 weeks, 1 year and ≥3 years from 226 ± 52 to 217 ± 47, 214 ± 44 and 200 ± 49 × 10(9)/l (p = 0.0464, 0.0164 and 0.0016), respectively. In conclusion, H. pylori infection upregulates platelet counts mainly in females, and eradication reduced peripheral platelets in both sexes. Females appeared more susceptible to H. pylori infection than males with regard to upregulation of platelet counts.

Abstract
Helicobacter pylori eradication is becoming a first-line therapy against idiopathic thrombocytopenic purpura (ITP) and its long term efficacy has already been reported. In contrast, eradication therapy reduced peripheral platelets in non-ITP patients 8 weeks later. To confirm the long term efficacy of Helicobacter eradication on platelet counts in non-ITP patients, we evaluated changes in peripheral platelet counts in endoscopically diagnosed patients with Helicobacter infection. Endoscopically diagnosed patients with Helicobacter infection received eradication therapy using amoxicillin (1500 mg/day), clarithromycin (400 mg/day) and lansoprazole (60 mg/day). The changes in platelet counts after Helicobacter eradication were serially evaluated for as long as 3 years or more. In total, 294 patients were enrolled: 243 patients successfully received eradication therapy and 51 were unsuccessfully treated. As a whole, peripheral platelet counts significantly decreased after Helicobacter eradication, being reduced by more than 1.0 × 10⁹/l by 5-6 months, 1 year, 2 years and 3 years or more (from 24.2+/-5.6 to 23.1+/-5.0, 23.0+/-5.0, 22.1+/-4.5, 22.4+/-5.6, and 21.6+/-5.3 × 10⁹/l: p = <0.0001, <0.0001, 0.0001, 0.0052, and <0.0001, respectively). Helicobacter pylori eradication finally reduced peripheral platelet counts around 2.0 × 10⁹/l in non-ITP patients. There was a definite difference in platelet regulation by Helicobacter pylori between ITP and non-ITP patients. These bivalent effects, upregulation and downregulation, on the peripheral platelet induced by Helicibacter pylori infection appeared to originate from quite different mechanisms.

Abstract
Today there is evidence that Helicobacter pylori has a critical role in different extragastric diseases. The discovery of a number of other novel Helicobacter species has stimulated the research in different extragastric diseases, in which an infectious hypothesis is plausible. Enterohepatic Helicobacter species have been hypothesized to play a role in different disorders, including hepatocellular carcinoma, gallstones formation and cholangiocellular carcinoma, as well as enteric diseases and inflammatory bowel diseases. Concerning the extragastric manifestations of H. pylori infection, idiopathic thrombocytopenic purpura, and sideropenic anemia represent, based on the current data, the diseases in which the pathogenic link appears to be strongest. There is also an increasing evidence for a possible association of H. pylori with cardiovascular disease.
