December 15. The survey of patients in the EUROHELICAN project was successfully completed in Alūksne

 

In the Alūksne research center, which was opened by the Institute of Clinical and Preventive Medicine of the University of Latvia on September 14, 2023, 340 patients were examined until mid-December.
 
The project "Accelerating the reduction of the spread of stomach cancer in Europe by eradicating H. pylori", or EUROHELICAN for short, is a project supported by the EU program EU - Health (EU4Health). As part of this, a population-based strategy for testing and eradicating the bacterium H. pylori will be evaluated. Infection with Helicobacter pylori or H. pylori significantly increases the risk of developing stomach cancer - most cases of stomach cancer are related to this infection. As a result of the project, world and European experts will develop recommendations for the implementation of gastric cancer prevention measures and for evaluating their effectiveness.

The researcher of the Institute of Clinical and Preventive Medicine of the University of Latvia, gastroenterologist Dr. med Danute Ražuka-Ebela said that this year the survey of the participants of the GISTAR study, which has been ongoing for 10 years, was started in three Latvian cities: in 2014. The work is currently being continued by the research center in Cēsis. 1150 people were surveyed within the project. We are very grateful to the research participants for the time invested in the name of a common goal."

On the other hand, in 2024, research centers will start working in other Latvian cities as well.
 
In Latvia, the EUROHELICAN project is led by the Institute of Clinical and Preventive Medicine of the University of Latvia (LU KPMI) in cooperation with the National Institute of Public Health of Slovenia (The National Institute of Public Health - NIJZ), the International Agency for Research on Cancer of the World Health Organization - IARC/WHO France), Nantes University Hospital (Nantes University Hospital, France) and Maribor Dr. Community Healthcare Center dr.

August 28. Successfully completed clinical activities of the HYCOR project at the Liepāja Research Center

 

On August 28, successfully completed the clinical activities of the HYCOR project at the Liepāja Research Center in collaboration with the Institute of Clinical and Preventive Medicine of the University of Latvia (LU KPMI) and the Liepāja Regional Hospital.

The GISTAR project, a multicenter randomized trial focused on reducing gastric cancer mortality through H. pylori eradication and pepsinogen measurement, served as the foundation for the implementation of the HYCOR project. HYCOR, short for hybrid-sensor breath analysis for colorectal cancer screening, represents an innovative approach in our ongoing research to devise strategies for reducing gastric cancer mortality in high-risk areas. Within the GISTAR study, a total of 11,223 participants participated, with 842 individuals being part of the study center in Liepāja.

Invitations were extended to healthy individuals between the ages of 40 and 64 to voluntarily participate in this scientific endeavor. Study participants were required to complete a comprehensive questionnaire, covering lifestyle factors, prior medical history, and any health-related complaints. Subsequently, selected participants expressing interest were invited for further investigations. While participants were randomly chosen, diagnostic tests were strongly recommended for those in immediate need of medical attention. A specific group of participants underwent blood tests to identify signs of gastric atrophy, a condition associated with an elevated risk of stomach cancer, and an occult blood test in stool to identify patients at higher risk of colorectal cancer. Those testing positive (showing abnormalities) were encouraged to undergo endoscopic examinations.

Out of the participants, 35 individuals were identified as needing colonoscopies (lower endoscopies) due to positive occult blood test results, with 23 of them already examined. Simultaneously, 22 study participants were invited to undergo upper endoscopy, with 16 having undergone the procedure. All participants were informed of their endoscopic findings, and when necessary, were referred to the appropriate specialists.

Among the 842 residents who participated in the study, 206 were found to be infected with Helicobacter pylori, a bacterium associated with stomach cancer development. These participants were prescribed eradication therapy for the bacteria, which they will continue until the end of August.

Additionally, at the Liepāja research center, research participants underwent specialized breath measurements using a hybrid breath analyzer. The objective of this endeavor was to develop a mathematical model for colorectal cancer detection and evaluate the sensor performance of a specially designed device for this purpose. While this device currently cannot provide an accurate diagnosis, it is contributing to the development of experimental technology for potential colorectal cancer screening. It's important to note that active analysis of the collected data and interpretation of results are ongoing.

The scientists engaged in the GISTAR study emphasize the significant global impact of digestive system tumors, accounting for a substantial portion of worldwide cancer cases. Annually, there are 3.88 million new diagnoses of this disease, resulting in 2.83 million fatalities. Colorectal (colon and rectal) cancer and stomach cancer are the most prevalent among these tumors. Importantly, many of these cancer cases can be prevented through timely diagnosis, as most digestive system tumors, including colorectal and stomach cancer, respond well to treatment when identified early. GISTAR stands as a scientific endeavor aimed at contributing to the reduction of gastric cancer mortality.

The leading international journal in gastroenterology and hepatology, "Gut" with the Impact Factor 31.795 has published a new scientific article “Clarithromycin-containing triple therapy for Helicobacter pylori eradication is inducing increased long-term resistant bacteria communities in the gut”. This study was conducted by scientists from UL ICPM (University of Latvia, Institute of Clinical and Preventive Medicine): Olga Sjomina, Reinis Vangravs, Elīna Ļeonova, Inese Poļaka, Dārta Pūpola, Kristaps Čivkulis, Sergejs Paršutins, Ilmārs Stonāns, and Mārcis Leja. Aleksandra Janiceka, a scientist from the Faculty of Medicine at the University of Latvia (represented also by prof. M. Leja un Elīna Ļeonova), also contributed to the research as well. International colleagues Dr. Jin Young Park from the International Agency for Research on Cancer and Prof. Lars Engstrand from the Department of Microbiology, Tumor and Cell Biology at the Karolinska Institute were part of the research team.

The importance of gut resistome induction following H. pylori eradication therapies has been debated for years, and the available information is controversial; the general thought is that normal gut microbiota is restored 3–6 months after antibiotic treatment. Therefore, a randomised controlled clinical trial as part of the GISTAR study in Latvia was conducted by evaluating alterations in gut microbiota before and 6 months after administering two treatment regimens for H. pylori eradication. The obtained results suggest that gut resistome remained increased for at least 6 months after the 14-day clarithromycin-containing regimen, which was not observed in the amoxicillin/bismuth-containing treatment and control groups. Based on the study's findings, the researchers propose that prior to implementing new antibiotic-based treatment protocols, such as those aimed at preventing gastric cancer, it is crucial to assess the long-term impact on the potential induction of gut resistome.

Study is implemented by ERDF (European Regional Development Fund ) within the framework of 2nd part of measure 1.1.1.1. "Practical Studies", project ID Nr. 1.1.1.1/18/A/184 "Optimisation of H.pylori eradication therapy for population-based gastric cancer prevention"

The GISTAR study, conducted in Liepāja by the University of Latvia Institute of Clinical and Preventive Medicine (UL ICPM) and the Liepāja Regional Hospital proves that every fourth resident of the Liepāja region should carefully monitor the health of their digestive tract.

Of the 584 residents who have participated in the study so far, 119 have been diagnosed with H.pylori, a bacteria promoting development of stomach cancer. In such cases, research participants are prescribed eradication therapy for the mentioned bacteria. For those study participants who are found to have deviations from the norm in their blood or fecal samples, which has been the case in another 30 cases, additional examinations are prescribed - upper endoscopy or colonoscopy.

The statistics of cancer of the digestive system in Latvia, in Europe and throughout the world are increasing every year. Every fourth newly diagnosed cancer develops in the digestive tract. Gastrointestinal tumors are the third leading cause of cancer deaths. Colorectal (colon and rectal) cancer and stomach cancer are the most common tumors of the digestive system. About 1,100 people are diagnosed with colorectal cancer and 700 die from it in Latvia annually. Every year, 500 - 600 inhabitants of Latvia fall ill with stomach cancer, which, compared to the indicators of European Union countries, is one of the highest in relation to the number of inhabitants. Scientists involved in the GISTAR study remind that a  detection of malignant tumors allows for successful treatment, which also significantly increases the survival rate of the patients.

Also currently, the residents of Liepāja and the surrounding area between the ages of 40 and 64 are invited to check upon health of their digestive tract. Free health examinations are held in Liepāja, 23 Jūrmalas Street, every working day from 7:00 a.m. to 1:00 p.m. More information about the the tests is available on the research website www.gistar.eu, application by phone - 25679868

The project is funded by the ERDF (European Regional Development Fund) 1.1.1.1. project ‘Practical Studies’, 4th phase, project ID Nr. 1.1.1.1/20/A/035 ‘Hybrid-sensor breath analysis for colorectal cancer screening’.

At the congress, L. Anarkulova presented the poster presentation "Application of modular multi-sensor VOC analyzer for non-invasive detection of colorectal cancer" that is based in the project HYCOR results. The poster presentation was on the screening of colorectal cancer with a breath analysis, based on the detection of volatile organic compounds in the breath using a sensor breath analyzer.

The aim of the study was to differentiate between colorectal cancer patients and individuals without cancer. Participants in these two groups – colorectal cancer patients and a control group - performed a breath test in a sensor breath analyzer. The obtained results showed that the sensor breath analyzer is able to distinguish between colorectal cancer patients and control group study participants. The study will be continued to build and evaluate more specific detection models in larger patient groups.
