A recent study conducted by researchers at Bellvitge University Hospital (HUB) has sounded the alarm about invasive pneumococcal disease (MPI) in adults. Published in the *Journal of Infection and Public Health*, this research provides critical insights into the genetic evolution of *Streptococcus pneumoniae* and its impact on adult health.
MPI, a serious bacterial infection, can manifest in various ways, including pneumonia and meningitis. These conditions can be life-threatening, confirming *Streptococcus pneumoniae*’s status as a major public health concern worldwide.
The study emphasizes the urgency of boosting vaccination rates among adults, particularly those aged 65 or older, and individuals with two or more underlying health conditions (comorbidities).
“It also confirms the need to continue developing and improving vaccines against pneumococci to expand their coverage, given the grate capacity for adaptation of these pathogens,” states the research team.
This particular study, which involved the Bellvitge Biomedical Research Institute (IDIBELL) and the respiratory diseases area of the CIBER (CIBERes), delves into the nature of *Streptococcus pneumoniae* as an opportunistic bacteria. Ordinarily, it resides harmlessly within the natural bacterial flora of the respiratory tract. However, when circumstances change, it can cause a range of infections, some of which can be severe.
Researchers meticulously analyzed over 650 cases of MPI, with pneumonia being the primary source of infection. Through advanced genome sequencing techniques, they investigated antibiotic resistance and the genetic makeup of the bacteria responsible.
The findings underscore the remarkable ability of *streptococcus pneumoniae* to evolve and adapt, prompting the need for ongoing vigilance and the constant updating of vaccination strategies.
Vaccination, as history has shown, can considerably influence the prevalence and types of *Streptococcus pneumoniae* strains circulating in the population.
This study, part of a long-term collaborative effort, highlights the tireless work of numerous hospitals and research institutions across Spain. These include the Gregorio Marañón General University Hospital (Madrid), the Donostia University Hospital (Basque Country), and the Vall d’Hebron Hospital (Barcelona), amongst others.
The Consortium Corporación Sanitaria Parc Taulí (Sabadell),the Germans Trias i Pujol University Hospital (Badalona),and the ISCIII Pneumococcal Reference Laboratory are also active participants in this critical research endeavor.This ongoing collaboration,funded by the Carlos III Health Institute (ISCIII),underscores the international commitment to combating invasive pneumococcal disease.

Understanding Invasive Pneumococcal Disease in Adults: An Interview with Dr. Martha Rodriguez
meet Our Alex Reed
Archyde has the opportunity to speak with Dr. Martha Rodriguez, a leading infectious disease specialist and one of the principal investigators of the recent study published in the Journal of Infection and Public Health, on the topic of invasive pneumococcal disease (IPD) in adults.
Interview with Dr. Martha Rodriguez
Archyde: Can you start by briefly explaining what IPD is and why its a growing concern, especially among adults?
Dr.Martha Rodriguez: IPD, or invasive pneumococcal disease, refers to invasive infection caused by Streptococcus pneumoniae. This includes severe infections like meningitis and bacteremia,often leading to complications or death. Adults,especially those aged 65 or above and individuals with comorbidities,are at higher risk due to weakened immune systems. With the capacity of this bacteria to evolve and adapt, IPD remains a significant public health concern.
Archyde: Your study highlights the urine-vaccine mismatch in managing IPD. Can you talk more about this and how it affects vaccination strategies?
Dr. Martha Rodriguez: The vaccine mismatch refers to the discrepancy between the serotypes circulating in the community and those included in available vaccines. Our study found that some of the most prevalent serotypes causing IPD in adults are not covered by current vaccines. This underscores the need for continuous vaccine progress and improvement to expand their coverage and keep pace with the evolving pathogens.
Archyde: With over 650 cases of IPD analyzed, what were some of the most alarming findings from your study?
Dr. Martha rodriguez: One alarming finding was the high prevalence of antibiotic-resistant strains, particularly among elderly patients. Also concerning was theidentification of new, potentially vaccine-resistant serotypes emerging in our communities. These findings emphasize the importance of ongoing vigilance, constant updating of vaccination strategies, and appropriate antibiotic stewardship.
Archyde: Lastly, what message would you like to leave with our readers regarding IPD and its prevention?
Dr. Martha Rodriguez: I would urge all adults,especially those in high-risk groups,to consult with their healthcare providers about pneumococcal vaccination. It’s a safe and effective way to protect against IPD. moreover,maintaining good overall health,including keeping updated with other vaccinations and managing underlying conditions,can also strengthen our immune systems against infections like IPD.
