CDC Study: Transplanted Lungs May Transmit Deadly Legionella Infection
Organ Transplant Recipients Die from Infected Donated Organs
Tragic news has emerged regarding two organ transplant recipients who have reportedly died from deadly bacteria that infected the donated organs. The U.S. Centers for Disease Control and Prevention (CDC) revealed that both patients had received lung transplants from the same donor, who tragically drowned in a river. The CDC suspects that the transplanted lungs were the source of the infection, which was caused by Legionella bacteria and resulted in Legionnaires’ disease, a severe form of pneumonia.
This shocking incident marks the first time that an organ transplant is believed to have spread Legionella bacteria. Legionnaires’ disease is typically contracted by inhaling water droplets contaminated with the bacteria. Approximately one in ten people with the disease succumb to its effects.
The CDC has issued a warning to clinicians, urging them to consider Legionella infection in patients who have received organs from donors who drowned in fresh water. Prompt diagnosis and treatment are crucial for increasing the chances of a full recovery.
Factors Pointing to the Transplanted Lungs as the Source
While the study did not provide definitive clinical or genomic evidence linking the transplanted lungs to the infection, it highlighted three factors that strongly suggest their involvement:
- The two patients had different species of Legionella, which could be explained by the diverse bacteria present in the river where the donor drowned.
- Water parameters at the hospital where the transplants took place remained within expected ranges, indicating that the hospital’s water system was unlikely to be the source of infection.
- No other cases of Legionnaires’ disease were reported from the transplant facility within a year of the two cases, further supporting the theory that the transplanted lungs were responsible.
Infection Symptoms and Risk Factors
Legionella bacteria are naturally found in freshwater environments but become a health concern when they contaminate human-made water systems. These systems include showerheads, hot water tanks, hot tubs, decorative fountains, and plumbing systems. Legionella can even grow in a vehicle’s windshield wiper fluid tank.
Once the bacteria enters these systems, it can spread through droplets that people inhale. However, it is important to note that the infection is not typically transmitted from person to person.
Individuals who are 50 years or older, current or former smokers, cancer patients, those with weak immune systems, chronic lung disease, and underlying illnesses like kidney failure, diabetes, and liver failure are at a higher risk of falling ill when exposed to Legionella.
Common symptoms of Legionnaires’ disease include shortness of breath, muscle aches, headaches, fever, and cough. These symptoms usually appear within two to 14 days after exposure to the bacteria.
While the mortality rate for the infection is approximately one in ten, it rises to one in four for individuals who contract the disease during a stay at a healthcare facility.
The CDC’s report also highlights a significant increase in Legionnaires’ disease cases over the past decade, with a peak of 2.71 cases per 100,000 persons in 2018. Most cases do not have a known source, although around 18 percent are associated with exposure in healthcare facilities.
It is worth noting that three additional organ transplant recipients received organs from the same donor, including a heart, liver, and right kidney. Although these patients experienced some complications, there was no indication of Legionella infection.
What infections can lung transplant recipients get?
Lung transplant recipients have a high rate of invasive fungal infections, with invasive aspergillosis (IA) being the most frequent culprit. Impaired cough reflex and mucociliary clearance of the host contribute to colonization and potential progression to invasive infection. The hospital during the same time period, further implicating the transplanted lungs as the source of infection.
This tragic incident serves as a reminder of the risks involved in organ transplantation and the importance of strict protocols to ensure patient safety. Organ procurement organizations and transplant centers must work together to minimize the chances of infection transmission. One crucial step is the meticulous screening of potential organ donors. It is essential to thoroughly assess the medical history of potential donors, including any recent infections or exposure to contaminated environments. This information can help identify potential risks and prevent the spread of infections through transplantation. In addition, transplant centers should follow strict guidelines for organ preservation and transportation to minimize the risk of bacterial contamination. Proper organ storage and transportation practices, including the use of sterile solutions and maintaining appropriate temperatures, can help decrease the chances of infection transmission. Furthermore, healthcare providers must be vigilant in monitoring organ transplant recipients for any signs of infection. Prompt diagnosis and immediate treatment are crucial for preventing complications and increasing the chances of a successful recovery. The tragic deaths of the two organ transplant recipients highlight the importance of thorough screening, prevention measures, and vigilant monitoring in organ transplantation. While this incident is an isolated case, it serves as a reminder that patient safety must always be the top priority in the field of organ transplantation. Organ transplant recipients, especially those who have received organs from donors who drowned in fresh water, should be aware of the risks and seek immediate medical attention if they experience symptoms such as high fever, chills, cough, and difficulty breathing. By learning from this unfortunate event, healthcare professionals can work towards further improving safety measures and protocols to protect organ transplant recipients from the risk of infection.Preventing Infections in Organ Transplants
