BACKGROUND: Hepatitis B surface antigen (HBsAg) clearance is vital for a functional cure of hepatitis B virus (HBV) infection. However, the incidence and predictors of HBsAg seroclearance in patients co-infected with HBV and human immunodeficiency virus (HIV) remain largely unknown in Guangdong, China. METHODS: Between 2009 and 2019, patients co-infected with HBV/HIV undergoing antiretroviral therapy (ART) in Guangzhou Eighth People's Hospital affiliated to Guangzhou Medical University were retrospectively reviewed with the endpoint on December 31, 2020. The incidence and risk factors for HBsAg seroclearance were evaluated using Kaplan-Meier and multivariate Cox regression analyses. RESULTS: A total of 1550 HBV/HIV co-infected patients were included in the study, with the median age of 42 years and 86.0% (1333/1550) males. Further, 98.3% (1524/1550) received ART containing tenofovir disoproxil fumarate (TDF) plus lamivudine (3TC). HBV DNA was examined in 1283 cases at the last follow-up. Over the median 4.7 years of follow-up, 8.1% (126/1550) patients achieved HBsAg seroclearance, among whom 50.8% (64/126) obtained hepatitis B surface antibody, 28.1% (137/488) acquired hepatitis B e antigen seroconversion, and 95.9% (1231/1283) undetectable HBV DNA. Compared with patients who maintained HBsAg positive, cases achieving HBsAg seroclearance showed no differences in age, gender, CD4 + T cell count, alanine aminotransferase (ALT) level, or fibrosis status; however, they presented lower HBV DNA levels, lower HBsAg levels, and higher rates of HBV genotype B at the baseline. Multivariate analysis showed that baseline HBsAg <1500 cutoff index (COI) (adjusted hazard ratio [aHR], 2.74, 95% confidence interval [95% CI]: 1.48-5.09), ALT elevation >2 × upper limit of normal during the first six months after receiving ART (aHR, 2.96, 95% CI: 1.53-5.77), and HBV genotype B (aHR, 3.73, 95% CI: 1.46-9.59) were independent predictors for HBsAg seroclearance (all P <0.01). CONCLUSIONS Long-term TDF-containing ART has high anti-HBV efficacy including relatively high overall HBsAg seroclearance in HBV/HIV co-infected patients. Lower baseline HBsAg levels, HBV genotype B, and elevated ALT levels during the first six months of ART are potential predictors of HBsAg seroclearance.

Direct-acting antivirals (DAAs) can strongly inhibit the replication of hepatitis C virus (HCV) and effectively clear the infection, but it may cause hepatitis B virus (HBV) reactivation, leading to severe liver damage and fulminate hepatitis in patients with HCV/HBV coinfection. In this review, we summarized the different replication process of HCV and HBV in infected hepatocytes and consequent innate immune response, and then discussed the molecular mechanism and clinical significance of HBV reactivation, and put forward the clinical precaution.

Clinically, patients with tuberculosis (TB) combined with hepatitis C virus (HCV) infection often require simultaneous treatment. Consequently, when anti-HCV and TB drugs are used in combination drug-drug interactions (DDIs), anti-TB drug-induced hepatotoxicity, and liver disease states need to be considered. This paper focuses on discussing the metabolic mechanisms of commonly used anti-TB and HCV drugs and the selection options of combined drugs, so as to provide rational drug use for TB patients combined with HCV infection.

Objective: To estimate the prevalence of HIV/HCV co-infection and explore the influence factors and their interaction on HIV/HCV co-infection of patient's access to methadone maintenance treatment (MMT). Methods: A face to face interviews were conducted among 750 patients at two MMT clinics in Guangxi Zhuang Autonomous Region. The questionnaires information included demographic characteristics, HIV and HCV infection status, history of drug abuse, urine test for morphine, high risk sex behaviors, needle sharing, dropped out etc. Methods of χ(2) test one-way, multivariate logistic regression and interactions were used to analyze the related factors of HIV/HCV co-infection. Results: The study subjects included 750 participants, 18.31% (127/691) of patients were co-infected with HIV and HCV. The HIV/HCV co-infection rate in patients who shared needles with others or dropped out of treatment was 35.84% (81/226) and 19.88% (64/322) respectively, which were higher than those who have never shared needles or dropped out (9.89%, 46/465 and 17.07%, 63/369). Logistic regression analysis results showed that after adjusted for confounding factors, patients who shared needles (OR=4.50, 95%CI: 2.72-7.43) and dropped out of treatment (OR=1.71, 95%CI: 1.04-2.80) were more likely to be infected with HIV/HCV. Interaction analysis showed that sharing needles and dropping out of treatment exist additive effect on co-infection of HIV and HCV (RERI=4.21, AP=0.44, SI=1.95). Conclusions: Needle sharing and dropping out of treatment are associated with HIV/HCV co-infection. Health education, psychological counseling and other measures should be taken to reduce needle sharing and dropping out of MMT.

BACKGROUND/AIMS: We investigated the time of onset of antituberculous drug-induced hepatotoxicity (ADIH) and related characteristics. METHODS: Adult patients (n = 1,031) treated with first-line antituberculous drugs between February 2009 and January 2013 were enrolled. RESULTS: Of the 1,031 patients, 108 patients (10.5%) developed ADIH a mean of 39.6 +/- 43.7 days after treatment initiation. Twenty-eight patients (25.9%) developed ADIH within 7 days, 73 (67.6%) within 30 days, and the rest after 30 days. The < or = 30-day group was characterized by higher peak alanine aminotransferase (ALT) level and a high proportion of patients with maintenance of first-line antituberculous drugs compared to the > 30-day group. In subgroup analysis, the < or = 7-day group was characterized by higher baseline aspartate aminotransferase and ALT, high proportion of patients with maintenance of first-line antituberculous drugs, and high proportion of patients with extrapulmonary tuberculosis compared to patients with ADIH that developed beyond 7 days. In multivariate analysis, serum ALT > 40 IU/L (odds ratio [OR], 2.995; 95% confidence interval [CI], 1.580 to 5.680; p = 0.001) and presence of anti-hepatitis C virus (OR, 4.204; 95% CI, 1.822 to 9.700, p = 0.001) were independent risk factors for development of ADIH. CONCLUSIONS: Approximately 70% of the cases of ADIH occurred in the first month of antituberculous treatment, and were associated with continuation of the first-line drug regimen.

INTRODUCTIONAtopic dermatitis is a common, chronic pruritic condition affecting both children and adults, which has a negative impact on the quality of life. These guidelines were developed by an expert workgroup appointed by the Dermatological Society of Singapore, to provide doctors with information to assist in the management of their patients with atopic dermatitis. The workgroup members are experienced dermatologists with interest and expertise in eczemas.

MATERIALS AND METHODSWorkgroup members arrived at a consensus on the topics to be included. Relevant studies from the literature were assessed for best evidence, supplemented by the collective experience of the workgroup.

RESULTSFor mild atopic dermatitis, emollients, mild potency topical steroids and topical calcineurin inhibitors are recommended. For moderate-to-severe atopic dermatitis, the use of emollients, moderate-to-potent topical steroids, topical calcineurin inhibitors, wet dressings, antimicrobials for secondary skin infection, phototherapy, and systemic therapy (e.g. prednisolone, cyclosporine, azathioprine or methotrexate) may be warranted. Patients with moderate-to-severe atopic dermatitis should be managed in conjunction with a dermatologist.

CONCLUSIONGood outcomes can be achieved with an individualised therapeutic approach combined with adequate patient and parental education.

BACKGROUNDThe prevalence of hepatitis B virus (HBV) infection is high among individuals infected with human immunodeficiency virus (HIV) in China. Both HIV and HBV can be treated with tenofovir disoproxil fumarate (TDF) and lamivudine (3TC), so we evaluated the safety and efficacy of combination antiretroviral therapy (ART) that included TDF, 3TC, and efavirenz (EFV) among ART-naive individuals who were co-infected with HIV and HBV.

METHODSOne hundred HIV/HBV co-infected ARV-naive individuals were started on the regimen of TDF, 3TC, and EFV, and the levels of plasma HBV DNA, HIV RNA, and biochemical evaluation related to the function of liver and kidney were analyzed.

RESULTSConcerning efficacy, this study found that by week 48, the vast majority co-infected participants receiving this ART regimen had undetectable HBV DNA levels (71%) and/or HIV RNA levels (90%). Concerning safety, this study found that the median estimated glomerular filtration rate of participants decreased from baseline (109 ml·min-1·1.73 m-2) to week 12 (104 ml·min-1·1.73 m-2) but was almost back to baseline at week 48 (111 ml·min-1·1.73 m-2).

CONCLUSIONThis combination ART regimen is safe and effective for patients with HIV/HBV co-infection.

OBJECTIVETo analyze the clinical manifestations of refractory Mycoplasma pneumoniae pneumonia (RMPP) which unresponded to methylprednisolone in the dosage of 2 mg/(kg·d) for 3 days.

METHODRetrospective analysis was performed on the clinical data of 110 children (64 boys and 46 girls) with RMPP. The patients were divided into "effective group" and "ineffective group" according to initial effect of 2 mg/(kg·d) methylprednisolone. The clinical manifestations, laboratory examination, radiological features and bronchofibroscopic findings of the children were compared. In order to seek the reference indexes which indicate nonresponsive to 2 mg/(kg·d) methylprednisolone, an ROC curve was made, of which the diagnostic cut-off was five independent correlation factors while grouping was made according to patients' different response to glucocorticosteroid.

RESULTThe effective group had 86 (86/110, 78.2%) children while ineffective group had 24 (24/110, 21.8%). The ineffective group children had the following performance: 16 children (16/24, 66.7%) in ineffective group had ultrahyperpyrexia (T ≥ 40 °C), which was significantly more severe compared to those in effective group (32/86, 37.3%, P < 0.01); the levels of white blood cell (WBC) count, percentage of neutrophils count (N), C-reactive protein (CRP), serum ferritin (SF), alanine transaminase (ALT), lactic dehydrogenase (LDH), creatine kinase isoenzyme (CK-MB) and fibrinogen (Fib) in ineffective group were significantly higher than those in effective group(P < 0.01); while percentage of lymphocyte count (L) was lower than that in effective group(P < 0.01). Proportion of mixed infection in ineffective group was higher than that in effective group (33.3% vs. 4.7%). Radiological manifestations: It was more frequently seen in ineffective group that chest CT scan indicated high density consolidation in no less than a whole pulmonary lobe and pulmonary necrosis (41.7% vs. 0%). Abundant secretions blockage (45.0% vs. 16.9%) and mucosal necrosis (37.5% vs. 8.1%) on bronchofibroscopy were more frequently seen in ineffective group. The critical values of the five independent correlation factors were CRP 110 mg/L, SF 328 mg/L, LDH 478 IU/L, N 0.78, L 0.13.

CONCLUSIONTreatment with 2 mg/(kg·d) methylprednisolone can improve clinical symptoms and radiological manifestations of most children with RMPP quickly, but it may be ineffective in some situations such as lasting high fever or ultrahyperpyrexia for more than 7 days, CRP ≥ 110 mg/L, N ≥ 0.78, L ≤ 0.13, serum LDH ≥ 478 IU/L, SF ≥ 328 µg/L, chest CT scan indicating high density consolidation in more than a whole pulmonary lobe involved and moderate-abundant pleural effusion.
