Les spécialistes du rein en Tunisie recommandent l'utilisation des solutions QuantiFERON de QIAGEN

TUNIS, Tunisie, 28 sept. 2023 (GLOBE NEWSWIRE) — QIAGEN annonce que l'utilisation de ses tests de la gamme QuantiFERON a t recommande par les cliniciens de la Socit Tunisienne de Nphrologie pour la prise en charge des patients greffs, dialyss et atteints de maladies rnales, marquant ainsi la premire recommandation de ce type au niveau mondial mise par un organisme professionnel spcialis dans la mdecine rnale.

Afin de mieux prvenir le plus tt possible les complications potentiellement mortelles pour ce type de patients, la Socit Tunisienne de Nphrologie, Dialyse et Transplantation Rnale (STNDT) conseille ses cliniciens d'utiliser QuantiFERON–CMV pour valuer la rponse immunitaire cellulaire spcifique au cytomgalovirus (CMV), QuantiFERON Monitor pour valuer l'intensit de la rponse immunitaire cellulaire en gnrale, et QuantiFERON–TB Gold Plus pour dpister l'infection tuberculeuse latente (ITBL) avant qu'elle ne devienne une maladie active.

Cette premire recommandation au monde par des spcialistes du rein constitue un vote de confiance en faveur des tests de rponse immunitaire QuantiFERON de QIAGEN , a dclar Simona GRANDITS, directrice ventes et marketing EEMEA chez QIAGEN. Les cliniciens de Tunisie trouveront en le QuantiFERON–CMV un outil innovant dans la prise en charge des patients compltant les tests PCR pour CMV. Par ailleurs, QuantiFERON Monitor et QuantiFERON–TB Gold Plus s'avreront inestimables pour surveiller des rponses immunitaires plus larges et spcifiques respectivement. Ces tests permettront la mise en place d'un traitement prventif personnalis, vitant ainsi l'utilisation excessive de mdicaments potentiellement toxiques et onreux .

Avec un taux d'incidence entre 8% et 32%, la maladie due au CMV reprsente la complication infectieuse la plus prvalente suite des interventions de greffe rnale. Les mdicaments immunosuppresseurs requis, essentiels pour viter le rejet d'organe, affaiblissent le systme immunitaire du patient, rendant plus difficile le contrle des infections virales. Le CMV post–greffe pose le risque de causer de graves complications telles une dtrioration directe de l'organe transplant, un dysfonctionnement ou rejet de greffe ainsi qu'une susceptibilit accrue d'autres infections.

Le contrle de la rponse immunitaire pour le CMV donne aux professionnels de sant la possibilit d'identifier les patients davantage risque de dvelopper des complications, leur permettant ainsi d'administrer des traitements adapts afin de rduire les risques de dveloppement d'une maladie lie au CMV ou que la greffe choue. En consquence, la STNDT conseille l'utilisation de QuantiFERON–CMV pour une surveillance nationale de la rponse immunitaire au cours de l'anne suivant l'intervention chirurgicale. Les patients avec un test QuantiFERON–CMV positif et une rponse immunitaire adquate face au virus pourront cesser le traitement prophylactique au bout de trois mois, tandis que ceux obtenant un test ngatif, plus risque de dvelopper la maladie due au CMV, devront tre surveills jusqu' six mois. Cette approche personnalise amliore non seulement les rsultats pour les patients, mais contribue galement la diminution des dpenses de sant. En effet la gestion de la maladie due au CMV pouvant tre particulirement coteuse, ces tests raliss pro–activement rduiront le cot de prise en charge en fournissant un soin cibl aux individus risque.

Pour aider les cliniciens dterminer la bonne posologie des mdicaments immunosuppresseurs afin d'viter la fois le rejet d'organe et les infections post–greffe, la STNDT recommande l'utilisation de QuantiFERON Monitor en accord avec l'intervention chirurgicale. La ralisation de tests avant une greffe rnale permet de mettre en place des mesures correctives pour les patients chez lesquels on dcle un faible systme immunitaire, tandis que les tests post–chirurgicaux aideraient les cliniciens ajuster le schma de mdicaments immunosuppresseurs administrer, crucial aprs toute greffe.

On estime qu'un individu sur quatre prsente une infection tuberculeuse latente, et que 5 10% de ces derniers pourraient dvelopper une tuberculose active, maladie contagieuse et potentiellement mortelle qui affecte gnralement les poumons. Les individus prsentant des dficiences de leur systme immunitaire sont bien plus risque de dvelopper une maladie active. Le STNDT conseille donc l'utilisation de QuantiFERON–TB Gold Plus pour le dpistage de la tuberculose dans des cas nphrologiques spcifiques, notamment les patients gs atteints d'insuffisance rnale chronique, ceux souffrant de comorbidits comme le diabte ou la malnutrition et les candidats une transplantation. De plus, il est recommand aux patients hmodialyss et ceux qui sont sur le point de commencer un traitement immunomodulateur en raison d'une insuffisance rnale. L'Organisation mondiale de la sant (OMS) recommande aussi fortement le dpistage de l'infection tuberculeuse chez tous les patients immunodprims, y compris ceux candidats une greffe d'organe ou hmatologique ainsi que les patients dialyss. QuantiFERON–TB Gold Plus ne ncessite qu'une visite du patient et est bien plus prcis pour dpister une ITBL dans les populations les plus susceptibles d'tre infectes, par rapport au test cutan la tuberculine (IDR), vieux de plus de cent ans, et qui requrait deux visites.

La technologie QuantiFERON de QIAGEN est une mthode de diagnostic in vitro unique pour dtecter les rponses immunitaires mdiation cellulaire partir d'chantillons de sang entier. Elle fonctionne en identifiant des lymphocytes T spcifiques chez des individus exposs des agents infectieux. Lorsqu'un antigne spcifique une infection est associ au sang, une rapide re–stimulation des lymphocytes T spcifiques l'antigne se produit, conduisant la scrtion d'interfrons gamma (IFN–), qui peuvent tre mesurs en guise de marqueur d'une rponse immunitaire.

QIAGEN’s QuantiFERON solutions recommended for use by kidney specialists in Tunisia

  • Tunisian Society of Nephrology first professional body in the field to publish nationwide guidance
  • Association of specialists recommends national immune response monitoring for cytomegalovirus (CMV) after kidney transplant
  • Professional vote of confidence in QuantiFERON–CMV, QuantiFERON Monitor and QuantiFERON–TB Gold Plus

TUNIS, Tunisia, Sept. 28, 2023 (GLOBE NEWSWIRE) — QIAGEN today announced that the comprehensive QuantiFERON immune response blood tests have been recommended for use by clinicians in Tunisia to help kidney disease, transplant and dialysis patients "" the world's first–ever guidance of this type by a professional body in kidney medicine.

To catch potentially deadly complications as early as possible, the Tunisian Society of Nephrology (TSN) advises specialist clinicians to use QuantiFERON–CMV to gauge the immune response of patients to cytomegalovirus (CMV), QuantiFERON Monitor to determine the strength of their immune systems more generally, and QuantiFERON–TB Gold Plus to detect latent tuberculosis infection (LTBI) before it becomes an active disease.

"The world's first recommendation by kidney specialists is a vote of confidence in QIAGEN's QuantiFERON immune–response tests," said Simona Grandits, Senior Director, Head of Sales and Marketing EEMEA at QIAGEN . "Clinicians in Tunisia will find QuantiFERON–CMV an innovative patient management tool to complement PCR testing for CMV "" and QuantiFERON Monitor and QuantiFERON–TB Gold Plus invaluable for monitoring specific and wider immune responses. They will be able to tailor preventive treatment and reduce the use of potentially toxic and costly medications."

With an incidence rate ranging from 8% to 32%1, CMV disease stands as the most prevalent infectious complication following kidney transplant procedures. The required immunosuppressive medications, essential for preventing organ rejection, weaken the patient's immune system, making it more challenging to control viral infections. Post–transplant CMV poses the risk of causing severe complications such as direct harm to the transplanted organ, graft rejection or dysfunction, and heightened susceptibility to other infections.

CMV immune response monitoring enables healthcare providers to pinpoint patients with higher risks of developing complications, thereby allowing them to administer suitable treatments and mitigate the chances of full–blown CMV disease and transplant loss. As a result, the TSN advises QuantiFERON–CMV to be used for nationwide immune response monitoring the year after surgery. Patients testing positive with an adequate immune response to the virus should be released from prophylactic treatment after three months, while those testing negative, and more at risk to CMV disease, should be monitored for up to six months. This tailored approach not only enhances patient outcomes, but also contributes to cost savings within the healthcare system. Managing CMV disease can be financially burdensome, and proactive testing helps to alleviate this burden by providing targeted care for those at risk.

To help clinicians determine the right dosage of immunosuppressive drugs to prevent both organ rejection and post–transplant infections, the TSN recommends the use of QuantiFERON Monitor before and after surgery. Testing before a kidney transplant allows for corrective measures for patients found to have weak immune systems, while post–surgical testing would aid clinicians in adjusting the regime of immunosuppressive medication that is crucial after any transplant.

One in four people are thought to have latent TB infections, with 5–10% of them expected at some point to develop active TB, a contagious and potentially deadly disease that usually affects the lungs. People with immune–system impairments are at a significantly higher risk of developing active disease. The TSN, therefore, advises the use of QuantiFERON–TB Gold Plus for tuberculosis screening in specific nephrological cases, including elderly patients with chronic renal failure, those with coexisting conditions like diabetes or malnutrition, and transplant candidates. Additionally, it's recommended for patients undergoing hemodialysis and those about to start immunomodulatory treatment due to renal insufficiency. The World Health Organization (WHO) also strongly recommends TB infection screening for all immunocompromised patients including those receiving organ or hematological transplants and those on dialysis. QuantiFERON–TB Gold Plus requires only one patient visit and is much more accurate for diagnosing latent TB in populations that are at the highest risk for infection than the century–old, two–visit Tuberculin skin test (TST).

QIAGEN's QuantiFERON Technology is a unique in vitro diagnostic method for detecting cell–mediated immune responses from whole blood samples. It works by identifying specific T–cells in individuals with infectious agent exposure. When an infection–specific antigen is combined with the blood, rapid re–stimulation of antigen–specific T–cells occurs, leading to the secretion of interferon–gamma (IFN–), which can be measured as a marker of an immune response.
