简要总结
Multidrug-resistant tuberculosis (MDR-TB) has emerged as a challenge worldwide. Few studies have prospectively reported outcomes in patients with pulmonary MDR-TB treated with adjunctive immunotherapy combined to standard chemotherapy. We aimed to assess whether immunotherapy with Interleukin(IL)-2 enhanced the clinical and immune effects of treatment on MDR-TB patients.We performed a multicentre prospective cohort study extend all over Jiangsu province in China. Two groups were generated based on the adjunctive rhIL-2 therapy during 24 months regiman. Bacteriological and imaging data were followed during 24 months with cure rates analysed.
详细描述
IL-2 therapy regimans are expected to restore the immune response or to change the immunologic status,thus allowing the host to more efficiently contain and eradicate immune responses, primarily those against cancers and infectious diseases.To address this, we performed a prospective randomized controlled multicenter cohort study of 8-month adjunctive immunotherapy with rhIL-2 for MDR-TB patients compared with the standard chemotherapy.
This multicenter prospective clinical study was conducted at 13 tuberculosis centers (coordinating hospital specialized in tuberculosis) across Jiangsu province, China. Joined by the network system of The First Affiliated Hospital of Nanjing Medical University and CDC of Jiangsu province, participants were enrolled from 2009 to 2018. This study protocol was approved by the ethics committee of the First Affiliated Hospital of Nanjing Medical University and was performed adhering to the ethical principles of the Declaration of Helsinki. All patients provided written informed consent before enrollment. The independent data and safety of the study were monitored by the hospital monitoring committee.
Patients enrollment
Eligible MDR-TB participants were identified by triplicate-spot sputum smears that were positive for acid-fast bacilli and a positive sputum culture with resistance to both isoniazid and rifampin, as determined by susceptibility tests and rapid screening tests . The results of these assays were confirmed using an L-G medium base modified in the Jiangsu province Centers for Disease Control and Prevention（CDC）.
Treatment plan for the two cohorts: The patients in rhIL-2 group were given consisted of four courses of low-dose rhIL-2 (500，000 U/m) given subcutaneously (SC) once every other day (q.o.d.) for 30 days. Four courses were carried out separately during months 1, 3, 5, and 7. All enrolled patients with pulmonary MDR-TB received a 24-month standard anti-MDR-TB chemotherapy regimen:6-month Z+KM/AM or CM + PAS/(Pa) + PTO +LFX as an intensive phase treatment, followed by an 18-month Z + LFX + PTO + PAS/(Pa) as a consolidation phase treatment.

研究组 & 干预措施
rhIL-2 Group
The patients in rhIL-2 Group were given consisted of four courses of low-dose rhIL-2 plus standard anti-tuberculosis chemotherapy. rhIL-2 (500，000U/m)regiman was given subcutaneously (SC) once every other day (q.o.d.) for 30 days and four courses were carried out separately during months 1, 3, 5, and 7. Standard anti-MDR-TB chemotherapy regiman was totally 24 months,including 6-month Z+KM/AM or CM + PAS/(Pa) + PTO +LFX as an intensive phase treatment, followed by an 18-month Z + LFX + PTO + PAS/(Pa) as a consolidation phase treatment.Then all the group patients were followed up for a minimum of 36 months.
干预措施: RhIL-2 (Drug)
