The new crown pneumonia epidemic eased, but pneumococcal “relay” hit Hong Kong. A specialist in respiratory system pointed out that the incidence of pneumococcus in Hong Kong continues to be high, and it not only affects young children and the elderly. Overseas research shows that in the middle-aged group aged 50 to 64, 2 out of 10 people are infected and cause meningitis The rate is higher than the elders. Among them, serotype 3 belongs to the “worst” type, and more than half of the infected patients are adult patients. Patients are highly resistant to commonly used antibiotics, making treatment more difficult. There was a 60-year-old woman who was infected with pneumococcus and developed pulmonary hemorrhage. She needed to be admitted to the ICU for up to 1 month.
Pneumonia is the second leading killer in Hong Kong. The incidence rate of pneumococcal disease has reached about 1.7 to 2.9 per 100,000 people from 2009 to 2019. In addition to infants and the elderly, the threat to adults cannot be ignored. Cao Zhonghao, a specialist in the respiratory system, pointed out that overseas studies have shown that the incidence rate of healthy people aged 50 to 64 is 20,000 per 100,000 people, which is similar to 24,000 per 100,000 people aged 65 or above; The rate of meningitis is higher, 60% for those aged 50 to 64, and only 51% for those over 65 years old, showing that the middle-aged are also at high risk.
Mortality due to multiple complications can be as high as 47%
Cao continued to point out that there are more than 100 serotypes of pneumococcus, about 30 of which can cause human infection, and serotype 3 is the “worst”, accounting for about 45% to 53% of invasive pneumococcal cases in Hong Kong from 2016 to 2020. It accounted for more than half of the cases, and nearly 70% of the children’s cases. “Recently, a 2-year-old girl developed white lung after infection.”
He said that serotype 3 cases are prone to multiple complications, such as bacteremic shock, etc., and the mortality rate can be as high as 47%. Some studies even pointed out that serotype 3 is resistant to commonly used antibiotics such as erythromycin and tetracycline in 54.6% and 71.2%, which increases the difficulty of treatment. Moreover, the toxicity of serotype 3 is higher than that of other serotypes, and its unique dependent pathway will protect the strain from phagocytosis and reduce the body’s protection against viruses, and the 13-valent and 23-valent vaccines selected by the Hong Kong subsidized vaccination program are not aimed at serotype 3 , “Some studies have inferred that existing vaccines require 8 times or more serotype 3 antibodies to effectively protect.”
A 60-year-old woman who is infected needs to be admitted to the ICU for 1 month
Cao also said that the 50-year-old group is mostly “sandwich people” at home. They have to take care of Gaotang at home and children at home. They are still very active in social and work, which may increase the risk of infection. “In addition, many people have chronic diseases. , such as diabetes, kidney disease, etc., are also prone to concurrent pneumonia.” A 64-year-old woman once contracted pneumococcus, developed severe pneumonia and sepsis, and had pleural effusion on the right side, requiring broad-spectrum antibiotics. Make a tracheostomy and use a ventilator. Cao said: “The patient can walk. Although he has diabetes and bronchiectasis, the degree is mild. However, after being infected with pneumococcus, his health is obviously much worse. After being discharged from the hospital, he has to use a wheelchair, and he still needs to use crutches for follow-up visits.”
