Management of chronic hepatitis B infection in women of childbearing age and measures and effects of prophylaxis and treatment of mother-to-child transmission Han Guorong, Chen Chao, Zhou Guanlun, Jiang Hongxiu 2021, 6 (4):  270-274.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.001 Abstract ( 334)    PDF (886KB) ( 582 )    China is now working with the world to achieve the goal of eliminating viral hepatitis by 2030. Chronic hepatitis B infection is a high pandemic in China. It is vital to eliminate hepatitis B virus infection from the source via blocking mother-to-child transmission (MTCT). The history of blocking hepatitis B MTCT has gone through nearly 30 years. Taking the effects of Department of Obstetrics and Gynecology, the Second Hospital of Nanjing, Nanjing University of Chinese Medicine in preventing hepatitis B MTCT as an example, more than 30 000 chronic HBV infected pregnant women and paired infants have been included in whole-process management and prevention in the past 20 years. Among them, more than 4000 HBV infected pregnant women have been treated with antiviral therapy. From 2010 to 2015, 4820 pregnant women with hepatitis B finished MTCT follow-op while 3607 maternal-infant pairs were in the follow-up between 2016 and 2019 with an overall MTCT rate of 99.7%. Based on evidence-based medical, the management process of HBV infected pregnant women, the standardized blocking of MTCT and long-term follow-up system of infants were first established and improved. The MTCT rate has decreased from 8%-10% in 2010 to 0.3% in 2020 by achieving the process of fertility counseling, preconception screening and evaluation, antiviral therapy, infant immunoprophylax and other measures. The results have been included in domestic and international guidelines for hepatitis B prophylaxis and treatment as vital evidence-based medical evidence and have been awarded the Outstanding Contribution Award of Antiretroviral Pregnancy Registry (APR). The clinical research results have been promoted and applied in nearly 100 hospitals nationwide and more than 5000 doctors have been trained, which established a typical model for preventing hepatitis B MTCT in China. Furthermore, great social and economic benefits were obtained. Further promotion of the overall process nationwide will realize the ultimate goal of eliminating hepatitis B.

Analysis of cellular immune function in patients with HBV/TP superinfection with different HBeAg status Chen Siyu, Bai Lan, Zhang Jin 2021, 6 (4):  298-301.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.007 Abstract ( 377)    PDF (906KB) ( 535 )    Objective To compare the cellular immune function of patients with hepatitis B virus/Treponema pallidum (HBV/TP) superinfection with different hepatitis B virus e antigen (HBeAg) status, and to further understand the changes of cellular immune function in patients with HBV/TP coinfection. Methods The clinical data of 79 patients with HBV/TP superinfection admitted to our hospital from January 2019 to January 2020 were retrospectively analyzed. All patients were divided into 2 groups according to the different HBeAg status before treatment, 41 HBeAg-positive patients were included in the HBeAg-positive group, and 38 HBeAg-negative patients were included in the HBeAg-negative group. The levels of HBV-DNA, T cell-related cytokines and T lymphocyte subsets in the peripheral blood of the two groups were compared. Results The level of HBV-DNA in the HBeAg-positive group was substantially higher than that in the HBeAg-negative group (P<0.05). The levels of CD3+T, CD4+T, CD4+T/CD8+T and natural killer (NK) cells in the HBeAg-positive group were higher than those in the HBeAg-negative group (P<0.05), and the CD8+T cell level was lower than that in the HBeAg-negative group (P<0.05). The levels of interferon-γ (IFN-γ), tumor necrosis factor (TNF-α), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-17 (IL-17), transforming growth factor-β (TGF-β) in the HBeAg-positive group were substantially higher than those of the HBeAg-negative group (P<0.05). The levels of interleukin-4 (IL-4) and interleukin-10 (IL-10) in the HBeAg-positive group were not significantly different from those in the HBeAg-negative group (P>0.05). Conclusion HBeAg level affects the immune function of patients with HBV/TP coinfection, which may induce the body to start cellular immunity, improve the level of T lymphocyte subsets and promote the secretion of related cytokines.

Bedaquiline in the treatment of pulmonary drug-resistant tuberculosis: safety and efficacy Yang Liangzi, Ren Tantan, Fu Xiangdong, Liu Zhi, Luo Lan, Zhang Peize 2021, 6 (4):  302-305.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.008 Abstract ( 592)    PDF (881KB) ( 610 )    Objective To evaluate the efficacy and safety of bedaquiline (BDQ)in patients with drug resistant pulmonary tuberculosis (DR-PTB)and to provide guidance for clinical rational and safe drug use. Methods We retrospectively reviewed 44 DR-TB patients (including multi-drug resistant pulmonary tuberculosis, MDR-PTB and extensively-drug-resistant TB (XDR-TB) treated with bedaquiline-containing regimen between January 2020 and August 2020 in the Third People's Hospital of Shenzhen. Results The conversion rate of acid-fast bacilli smear was 97.4%(38/39) and the culture conversion rates was 92.9%(26/28) at 24 weeks. There were 49 adverse events in total, including 18 cases of prolonged QTc interval (36.7%) and 10 cases of liver toxicity (20.4%). Among the 18 QTc prolonged adverse events, 3 were clearly related to bedaquiline, accounting for 6.1% of the total adverse events. Treatment was halted in four patients because of prolonged corrected QTc interval, one of which was associated with a single factor of bedaquiline. Conclusion Bedaquiline-containing regimen was effective and safe for patients with pulmonary DR-TB. But it was still necessary to closely monitor adverse reactions, especially the occurrence of prolonged QTc interval.

A retrospective cohort study of clinical characteristics and treatment regimens of drug-resistant tuberculosis containing isoniazid-resistance Fu Liang, Liao Weiming, Zhang Huihua, Deng Guofang 2021, 6 (4):  306-310.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.009 Abstract ( 445)    PDF (889KB) ( 606 )    Objective To analyze the clinical characteristics and treatment regimens of drug-resistant tuberculosis containingisoniazid-resistance (Hr)DR-TB patients, and provide evidence for clinical practice and further research. Methods We retrospectively enrolled patients with (Hr)DR-TB, including Hr-TB and multidrug-resistant tuberculosis (MDR-TB) during January 2011 to December 2016 in Shenzhen Third People's Hospital, collected the demographic data, history of anti-tuberculosis treatment, phenotypic drug susceptibility testing (pDST) results of Mycobacterium tuberculosis and the changes of pDST, treatment regimens and adjustment strategy, treatment outcomes, and divided these data into new cases and retreated cases for comparative analysis. Results ①There are 37.5% (232/619) of Hr-TB and 62.5% (387/619) of MDR-TB in total, 49.7% and 50.3% in new cases, and 22.8% and 77.2% in retreated cases. Some patients experienced changes in the drug resistance spectrum during anti-tuberculosis treatment or after TB recurrence. 10.8% (67/619) of anti-tuberculosis drugs changed from drug-susceptible to drug-resistant.7.4% (46/619) changed from drug-resistant to drug-susceptible. ②Among 235 cases of Hr-TB, according to the pDST results, 8.5% (20/235) of patients with levofloxacin resistance and 8.9% (21/235) of patients with ethambutol resistance were found. Among the retreated cases, levofloxacin-resistant patients accounted for 20.9% (14/67), which was more than that in new cases (20.9% vs 3.6%, P>0.05). Among those who were sensitive to levofloxacin, 80.5% (167/215) used isoniazid in the initial regimen. Among those resistant to levofloxacin, 70% (14/20) used levofloxacin. After the pDST was reported, most cases (86.4%, 203/235) ignored the results and did not adjust their regimens. In terms of treatment outcome, 71.5% (168/235) were lost to follow-up, and 26.4% (62/235) maintained in the cohort. The treatment success rate of newly cases was higher than that of retreated cases (29.8%, 50/168 vs 16.4%, 11/67, P<0.01). Conclusion The most of (Hr)DR-TB patients were young and middle-aged men, and most of them were combined with rifampicin resistance. The drug resistance spectrum was easy to change during treatment. During the treatment of HR-TB, the treatment was rarely adjusted according to drug sensitivity, and more than 70% of cases were lost to follow-up. Attention should be paid to the standardized diagnosis and treatment of (HR) Dr-TB, especially Hr-TB.

Methods The clinical data of 1134 children with lower respiratory infection (LRI) in Hubei Maternal and Child Health Hospital from January 2017 to December 2019 were collected. Based on retrospective research method, the unified clinical research forms were formulated to read the clinical data of children in detail. The related data were collected and summarized, including gender, age, admission time, clinical symptoms and test results of MP antibody. Results Among the 1134 LRI children from 2017-2019, there were 155 cases (13.67%) with positive MP. The ratios of MP infection in 2017, 2018 and 2019 were 14.40%, 11.17% and 15.49%, respectively. And the difference was not statistically significant (P>0.05). The ratios of MP infection in males and females were 13.11% (78/595) and 14.29% (77/539), and the difference was not statistically significant between the groups (P>0.05). The ratio of MP infection was gradually increased with age. The ratio of MP infection was the lowest in LRI children aged 0-3 years (10.26%), followed by 4-5 years old (15.41%) and 6-14 years old (16.44%). After comparison, ratio of MP infection in LRI children aged 0-3 years was significantly lower than that aged 4-5 years old and 6-14 years old (P<0.05). There was MP infection throughout the year, with the highest ratio of MP infection within October-December (17.21%), followed by January-March (14.01%), April-June (10.67%) and July-September (9.28%). After comparison, ratio of MP infection within October-December was significantly higher than that within April-June and July-September (P<0.05). Conclusion Children aged 4-14 years old are the susceptible population. The main symptoms include cough, fever and wheezing. And the disease is more likely to appear in autumn and winter.

Research progress of the impact of COVID-19 on AIDS patients worldwide Zhan Xiangming, Lu Hongzhou 2021, 6 (4):  356-360.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.021 Abstract ( 490)    PDF (890KB) ( 636 )    The coronavirus disease 2019 is spreading all over the world, triggering a global crisis of medical and health resources, and leading to the reduction or interruption of HIV prevention and treatment services. Studies by many countries and health institutions have pointed out that HIV infection is not directly related to the poor prognosis of COVID-19 but indirectly causes difficulties in obtaining medical resources for HIV positive patients, inadequate antiretroviral treatment, and decline in mental health. As a result, the infection and fatality rate of some HIV positive people in COVID-19 have increased. The reason may be related to the epidemic prevention policies of various countries. This article reviews the impact of COVID-19 on the infection and fatality rate of HIV positive people, the existing problems of HIV positive individuals during the COVID-19 epidemic, and current recommendations and countermeasures. It is expected to provide reference for PLWH in the prevention and treatment of COVID-19.

The global tuberculosis report 2021: key data analysis for China and the global world Lu Chunrong, Fang Hongxia, Lu Puxuan, Ji Lecai 2021, 6 (4):  368-372.  DOI: 10.19871/j.cnki.xfcrbzz.2021.04.023 Abstract ( 1377)    PDF (991KB) ( 3136 )    The global tuberculosis(TB) report 2021 provides a comprehensive overview of the global situation of TB, the impact of Coronavirus disease 2019(COVID-19) pandemic on TB control, the progress in achieving TB milestones, diagnosis and treatment. The report shows that worldwide, an estimated 9.9 million people fell ill with TB in 2020, equivalent to 127 cases per 100 000 population, but only 5.8 million cases were notified in 2020. That were 4.1 million cases off estimate. Best estimates for 2020 are 1.3 million TB deaths among HIV-negative people and an additional 214 000 among HIV-positive people, with the number of deaths increasing and the incidence of the disease declining slowly. The 2021 Report suggests that our progress towards achieving TB milestones and targets had been hit hard by the COVID-19 pandemic. It will be have a more adverse effect in 2021 and later. It is an urgent need to take action, such as recover the accessibility of basic service of TB, increase the application and popularization of the technology of digital health, increase investment in capital and research for TB services, and try our best to reduced reverse the adverse impact of the COVID-19 pandemic on TB. We strive to realize the beautiful vision of “a world free of TB” as soon as possible!
