Vaccine helps to prevent and control tuberculosis Positive the infeted are apter to recur
It is caused that the recurring of tuberculosis can infect tubercle bacillus or original disease and recur again. A few days ago, the hygiene of London of Britain and researcher of the tropical medical college found, the infection rate increases at HIV patient's tuberculosis. Its result of study is published on the recent " lemology periodical ".
Positive the infeted are apter to recur
HIV is infected with and can increase tuberculosis new morbidity and recuring rate, but tuberculosis formed because the tubercle bacillus is infected again recurs, it is or not that the incidence in HIV infects is not yet clear to infect in HIV. Hygiene and tropical Dr. JudithR of medical college and his colleague of London of Britain have analysed and researched the situation of recuring of South African gold mine workers' tuberculosis, 342 people of HIV person who infects masculine gender among them, HIV infects 321 persons of the negative one, has participated in the early research about sending pulmonary tuberculosis newly.
The result of study reveals, in HIV infects the miner of the masculine gender, 34% present the tuberculosis to recur, infect in the negative miner in HIV, 21% recur tuberculosis only. According to calculation this, midyear such as every 100 people, HIV-positive the infeted have illness coming on again the example is counted (19.7) Higher than HIV, infect getting negative obviously ' 7.7) .
Vaccine can offer effective protection
Influence factor that tuberculosis recur there are a lot of, until tuberculosis have illness coming on in the patient of the history once, HIV recuring rate of tuberculosis caused to infect increase greatly ' The risk is to 2.8) ; In addition, isonicotinyl hydrazine able to bear tubercle bacillus of medicine infect, change from the intersection of HIV and serum issue infect total length that sustain before the issue to HIV the taking place rate had sure influence and then to tuberculosis too. And infect the male patient of the masculine gender to HIV, the time that the first tuberculosis has illness coming on relates to recurring rate, especially have illness coming on at tuberculosis for the first time in 2 years, the recuring rate of tuberculosis of the infeted of male HIV is higher.
Researchers say, after minimizing the possible factor resulting in recuring, in HIV infects the negative and positive patient, the recuring rate may be 3 times that of sending rate for the first time of tuberculosis. Tubercle bacillus tuberculosis of person who is infect with recur again, so many higher than the beginning morbidity, indicate more easily infected group have heterogeneity, mean that can still offer effective protection to crowd through the inoculation of vaccine, and can strengthen second prevention to that tuberculosis recurs of patient.
American Maryland State Barr rubs the university Dr. RichardE of Sri Lankan of Hopkin, John of city, the intersection of fort and the intersection of and GavinJ of hygiene research institute Dr. Luo, Johannes of South African, say, approve to conclusion of research this, they write, develop one prevent and control tuberculosis take place and recur for the first time effectively in not commenting Basic vaccine latent energy is getting larger very,even so, let's prevent tuberculosis two methods best that be had illness coming ons, take precautions against the happening for the first time of tuberculosis after all.
