Sepsis caused by Klebsiella pneumoniae after multifetal pregnancy reduction: a case report
This case report details a rare instance of *Klebsiella pneumoniae*-induced sepsis and subsequent fetal loss following multifetal pregnancy reduction, emphasizing the critical need for preoperative microbiome screening and multidisciplinary management to prevent postoperative intrauterine infections in assisted reproductive procedures.

Modern medicine has given many couples who struggle to conceive a path to parenthood through assisted reproductive technologies. These medical interventions, which include stimulating the ovaries to release eggs and placing embryos into the uterus, have helped countless families grow. However, these powerful tools carry a specific risk: they can sometimes result in a pregnancy with more than one baby at a time. When a woman carries three or more fetuses, the risks to both her health and the babies' survival rise significantly. To protect everyone involved, doctors often recommend a delicate procedure called multifetal pregnancy reduction. This involves carefully removing one or more fetuses early in the pregnancy to allow the remaining ones to develop safely. While this procedure is generally safe and effective, the human body is a complex system, and even rare complications can have severe consequences.
A recent case report from a hospital in China details a rare and dangerous complication that occurred after such a procedure. A twenty-nine-year-old woman, who had a history of fertility issues and a condition affecting her hormone levels, successfully conceived triplets through in vitro fertilization. Following medical advice, she underwent a procedure to reduce the number of fetuses from three to two. The surgery itself went smoothly, and for the first day afterward, she seemed to be recovering well. However, her condition took a sharp turn for the worse. She developed a high fever, and her body began to show signs of a severe systemic infection. Doctors discovered that a bacterium called Klebsiella pneumoniae, which can live harmlessly in the body but cause serious illness when it enters the bloodstream, had invaded her system. This infection led to sepsis, a life-threatening reaction where the body's immune response damages its own tissues, and ultimately caused the loss of the remaining twins.
The medical team faced a difficult challenge as they worked to save the mother's life. Initially, the woman's symptoms, including a sore throat and mild congestion, led doctors to suspect a common throat infection. They treated her with standard antibiotics, but her fever spiked to dangerous levels, reaching forty degrees Celsius. Blood tests revealed that her white blood cell count, which usually fights infection, had dropped dangerously low, while markers of severe inflammation in her blood soared. It became clear that the infection was not just in her throat but had spread through her blood. The medical team consulted specialists in infectious diseases, who identified the specific bacteria causing the crisis. They switched her treatment to a powerful antibiotic known as meropenem, which is effective against tough bacterial strains. Despite the aggressive treatment, the infection persisted, and the bacteria continued to thrive in the uterus.
The turning point in the case came when the doctors realized that the source of the infection was trapped inside the womb. The remaining pregnancy tissue provided a perfect environment for the bacteria to multiply, shielding them from the antibiotics circulating in the blood. To stop the infection from killing the mother, the medical team had to make the heartbreaking decision to remove the pregnancy tissue. Once the infected material was cleared from the uterus, the woman's fever broke, and her blood tests began to return to normal. She recovered fully from the infection. In a remarkable turn of events, she went on to conceive naturally two more times in the following years, delivering healthy babies via cesarean section each time.
This case offers a critical lesson for medical practice regarding safety before surgery. The woman had a history of frequent throat infections and was showing mild signs of a respiratory issue at the time of her procedure. The report suggests that any sign of active infection in the body, even one as seemingly minor as a sore throat, should be a reason to postpone invasive surgery on a pregnant woman. The bacteria likely traveled from her throat or another part of her body into her bloodstream during the procedure. The authors emphasize that before performing such delicate operations, doctors must rigorously check for infections in every part of the body, not just the reproductive system. They also recommend testing the bacteria present in the reproductive tract to ensure no dangerous pathogens are waiting to cause trouble.
The story of this patient highlights the importance of a coordinated medical response when things go wrong. It was the quick involvement of infectious disease specialists and the willingness to escalate treatment that saved the mother's life. While the loss of the twins was a tragedy, the successful recovery of the mother and her ability to have children later shows that the body can heal from even the most severe infections if the source is removed and the right treatment is given. The report concludes that strict screening for infections and a readiness to act quickly with the help of multiple medical experts are essential to keeping mothers and babies safe during these complex procedures.
