Objective:To explore the early differential diagnosis method by comparing the clinical characteristics of acquired immunodeficiency syndrome (AIDS) patients complicated with tuberculous meningitis (TBM) and cryptococcus neoformans meningitis (CNM).Methods:The AIDS patients admitted to Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 2011 to February 2022 and diagnosed with combined TBM and CNM after discharge respectively were included. A retrospective study was performed to analyze the clinical features of 21 AIDS patients complicated with TBM (TBM group) and 54 AIDS patients with CNM (CNM group) (all cases were confirmed by etiology). The data of meningitis-related symptoms and signs, blood routine test, CD4 + T lymphocyte counts, imaging characteristics and cerebrospinal fluid examination at admission were collected and analyzed. Statistical analysis was performed by using independent sample t test, rank sum test or chi-square test. Results:The age of patients in the TBM group was (44.6±12.9) years old, which was older than that of patients in the CNM ((37.6±12.6) years old), the difference was statistically significant ( t=-2.15, P=0.035). Forty-eight cases (88.89%) and seven cases (12.96%) in the CNM group experienced headaches and consciousness disorders respectively, with statistically significant differences compared to those in the TBM group (13 cases (61.90%) and nine cases (42.86%), respectively) ( χ2=7.25, P=0.007 and χ2=8.05, P=0.005, respectively). The proportion of leukopenia was 27.78%(15/54), and proportion of thrombocytopenia was 16.67%(9/54) in the CNM group, which were higher than those in the TBM group (4.76%(1/21) and 0(0/21), respectively), and the differences were statistically significant ( χ2=4.77, P=0.029 and χ2=3.98, P=0.042, respectively). The CD4 + T lymphocyte count in the TBM group was 74.0(92.0)/μL, which was higher than 19.5(56.5)/μL in the CNM group, and the difference was statistically significant ( Z=-2.87, P=0.009). The CNM group had 46 cases (85.19%) with cerebrospinal fluid pressure >180 mmH 2O(1 mmH 2O=0.009 8 kPa) and 24 cases (44.44%) with cerebrospinal fluid pressure >330 mmH 2O, which were significantly higher than those in the TBM group with seven cases (33.33%) and four cases (19.05%), respectively, and the differences were statistically significant ( χ2=19.61, P<0.001 and χ2=4.17, P=0.041, respectively). Fifty-two point three eight percent (11/21) of patients in the TBM group had a white blood cell counts>200×10 6/L in the cerebrospinal fluid, which was higher than that in the CNM group (1.85%(1/54)), with a statistically significant difference ( χ2=27.23, P<0.001). The white blood cell counts, protein and adenosine deaminase levels in the cerebrospinal fluid of TBM group were significantly higher than those in the CNM group (200.00(579.50)×10 6/L vs 17.50(66.25)×10 6/L, 1 863(2 858) mg/L vs 672 (513) mg/L and 6.60 (8.55) U/L vs 1.95(2.60) U/L, respectively), and the cerebrospinal fluid chloride level was lower than that in the CNM group ((107.71±8.22) mmol/L vs (115.99±6.55) mmol/L), and all the differences were statistically significant ( Z=4.11, P<0.001, Z=21.23, P=0.008, Z=2.09, P=0.040 and t=4.57, P<0.001, respectively). There was no significant difference in cerebrospinal fluid glucose between the TBM group and the CNM group ((1.86±1.22) mmol/L vs (2.34±1.05) mmol/L, t=-1.72, P=0.090). The proportion of patients with bilateral lung lesions in the TBM group was higher than that in the CNM group, and the difference was statistically significant (100.00%(21/21) vs 40.74% (22/54), χ2=-6.53, P=0.011). Conclusions:Patients with AIDS complicated with TBM are more likely to have consciousness disorders, inflammatory response in the cerebrospinal fluid, and more bilateral lung lesions. In contrast, patients with AIDS complicated with CNM are more frequently to experience severe headache and significant elevation of cerebrospinal fluid pressure, leukopenia and thrombocytopenia, and lower peripheral blood CD4 + T lymphocyte counts.

BACKGROUND: There is limited data to comprehensively evaluate the epidemiological characteristics of multiple myeloma (MM) in China; therefore, this study determined the characteristics of the disease burden of MM at national and provincial levels in China. METHODS: The burden of MM, including incidence, mortality, prevalence, and disability-adjusted life years (DALYs), with a 95% uncertainty interval (UI), was determined in China following the general analytical strategy used in the Global Burden of Disease, Injuries, and Risk Factors Study 2019. The trends in the burden of MM from 1990 to 2019 were also evaluated. RESULTS: There were an estimated 347.45 thousand DALYs with an age-standardized DALY rate of 17.05 (95% UI, 12.31-20.77) per 100,000 in 2019. The estimated number of incident case and deaths of MM were 18,793 and 13,421, with age-standardized incidence and mortality rates of 0.93 (95% UI, 0.67-1.15) and 0.67 (95% UI, 0.50-0.82) per 100,000, respectively. The age-specific DALY rates per 100,000 increased to more than 10.00 in the 40 to 44 years age group reaching a peak (93.82) in the 70 to 74 years age group. Males had a higher burden than females, with approximately 1.5- to 2.0-fold sex difference in age-specific DALY rates in all age groups. From 1990 to 2019, the DALYs of MM increased 134%, from 148,479 in 1990 to 347,453 in 2019. CONCLUSION The burden of MM has doubled over the last three decades, which highlights the need to establish effective disease prevention and control strategies at both the national and provincial levels.

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.

Objective:To investigate the risk factors of low-level viremia (LLV) among human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients after combined anti-retroviral therapy (ART), and to provide evidence for reducing the risk of LLV.Methods:It was a cross-sectional observation study that enrolled HIV/AIDS patients with LLV (plasma HIV-1 RNA was 50 to 1 000 copies/mL) receiving ART over one year (LLV group) from January 2019 to December 2020 in Guangzhou Eighth People′s Hospital, Guangzhou Medical University. Contemporaneous patients with ART over one year and successful viral suppression (plasma HIV-1 RNA<50 copies/mL) were randomly selected as the control group (suppression group) with a ratio of 1∶2.5, and the risk factors for LLV were analyzed by unconditional logistic regression.Results:A total of 128 and 297 patients were enrolled in LLV group and the suppression group, respectively.ART durations were 3.62(1.83, 4.89) years and 4.91(2.90, 5.88) years, respectively. Multivariate logistic regression analysis showed that the risk factors associated with LLV included the age of initial ART treatment above 50 years old (odds ratio ( OR)=1.82, 95% confidence interval ( CI) 1.01 to 3.26, P=0.046), the baseline HIV-1 RNA over 1×10 5 copies/mL ( OR=2.18, 95% CI 1.30 to 3.68, P=0.003), using the simplified initial ART regimen ( OR=1.82, 95% CI 1.02 to 3.26, P=0.044), missing medication more than three times per year ( OR=2.49, 95% CI 1.55 to 4.01, P<0.001) and changing regimen during ART ( OR=1.90, 95% CI 1.14 to 3.14, P=0.013), while the duration of ART longer than five years could reduce the risk of LLV ( OR=0.37, 95% CI 0.22 to 0.64, P<0.001). In patients with simplified initial ART regimen, the baseline CD4 + T lymphocyte count of whom with LLV was lower than that of whom with viral suppression, and the difference was statistically significant (94.00 (24.00, 281.00)/μL vs 375.00 (310.00, 435.00)/μL, Z=-2.60, P<0.001). Conclusions:The occurrence of LLV is related to the age of initial ART treatment, the baseline HIV-1 RNA, the initial ART regimen, the medication adherence and the change of ART regimen during ART. Strategies may be beneficial to reducing the risk of LLV for HIV/AIDS patients, such as initiating ART as soon as possible, using simplified regimen as initial regimen with caution in patients with low baseline CD4 + T lymphocyte counts, strengthening compliance education, avoiding unnecessary ART regimen changes.

Background::Chronic liver disease has emerged as a leading cause of non-acquired immune deficiency syndrome (AIDS)-related mortality in hepatitis C virus (HCV)/human immunodeficiency virus (HIV)-coinfected patients. The relationship between CD4 cell count and HIV-related opportunistic infections and tumors has been well characterized; however, it is unclear whether CD4 cell count is associated with HCV-related hepatic events.Methods::This observational cohort study enrolled HCV/HIV-coinfected patients from the National Free Antiretroviral Treatment Program of China from 2004 to 2019 in Guangzhou. The primary outcome was a composite of hepatic events, including cirrhosis complications, hepatocellular carcinoma (HCC), and liver-related mortality. Kaplan-Meier survival and multivariate logistic regression analyses were performed.Results::Among the 793 patients, 43 developed hepatic events during a median follow-up of 6.7 years, including 35 cirrhosis complications, 13 HCC cases, and 14 cases of liver-related mortality. The 5-year and 10-year cumulative incidences of hepatic events were 4.2% and 9.3%, respectively. Patients who developed hepatic events had a less satisfactory increase in CD4 cell count, lower peak CD4 (354.5 cells/μL vs. 560.0 cells/μL, P < 0.001), and lower percentage of peak CD4 > 500 cells/μL (30.2% vs. 60.7%, P < 0.001) after the initiation of antiretroviral therapy (ART) than those who did not. The cumulative incidences of hepatic events were higher in patients with lower peak CD4 levels with adjusted odds ratios of 3.96 (95% confidence interval [CI]: 1.51-10.40), 2.25 (95% CI: 0.87-5.86), and 0.98 (95% CI: 0.35-2.74) for patients with peak CD4 at <200 cells/μL, 200-350 cells/μL, and 351 to 500 cells/μL, respectively, relative to those with peak CD4 > 500 cells/μL. Peak CD4 was negatively associated with the risk of hepatic events in a dose-response manner ( P-value for trend = 0.004). Conclusion::Persistently low CD4 cell counts after ART are independently associated with a high risk of hepatic events in HCV/HIV-coinfected patients, highlighting the important role of immune reconstitution in improving liver outcomes.

Objective To investigate the efficacy of switching to co-formulated elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/c/F/TAF) combined with sofosbuvir/velpatasvir (SOF/VEL) in the treatment of previously untreated chronic hepatitis C patients with HIV/HCV co-infection and the changes in blood lipid levels. Methods This prospective cohort study was conducted among 10 previously untreated chronic hepatitis C patients with HIV/HCV co-infection who attended Department of Infectious Diseases in Tangdu Hospital from July 2019 to May 2021 and achieved continuous HIV suppression after antiretroviral treatment (ART). As for anti-HIV therapy, the ART regimen was switched to the E/c/F/TAF regimen for 32 weeks, and for anti-HCV therapy, the SOF/VEL regimen was started since week 4 after switching and lasted for 12 weeks. Related indices were monitored before and after switching to E/c/F/TAF for anti-HCV therapy and SOF/VEL for anti-HCV therapy, including body weight, body mass index, HCV genotype, alpha-fetoprotein, liver stiffness measurement, CD4 + T cell count, CD4 + T/CD8 + T ratio, hepatic and renal function parameters, blood lipids, HIV RNA, HCV RNA, SVR12, SVR24, and adverse reactions. The Mann-Whitney U test was used for comparison of continuous data between two groups, and a Spearman correlation analysis was performed. Results After 4 weeks of treatment with E/c/F/TAF, 10 patients (HCV genotypes 2a and 1b) had HIV RNA below the lower limit of detection (20 IU/ml) and a significant reduction in albumin ( Z =-2.801, P =0.003 7), with the other indices remaining stable, and the patients reported significant improvements in the adverse events of anti-HIV therapy with the former ART regimen. After 4 weeks of E/c/F/TAF combined with SOF/VEL, the patients had HCV RNA below the lower limit of detection (15 IU/ml), and both SVR12 and SVR24 reached 100%; after 12 weeks of anti-HCV therapy, there were significant reductions in alanine aminotransferase ( Z =-2.732, P =0.004 8) and aspartate aminotransferase ( Z =-2.501, P =0.010 7) and significant increases in total cholesterol (TC) ( Z =-2.797, P =0.003 9) and low-density lipoprotein cholesterol (LDL-C) ( Z =-2.343, P =0.018 5), with a significantly positive correlation between them ( r =0.87, P < 0.001), and all the other indices were normal. Conclusion For previously untreated chronic hepatitis C patients with HIV/HCV co-infection, switching to E/c/F/TAF combined with SOF/VEL has good efficacy, tolerability, and safety, and the combination of the two regimens can avoid drug interaction, achieve a high HCV cure rate, and maintain HIV suppression. Transient increases in TC and LDL-C are observed during combination treatment, which suggests dyslipidemia caused by HCV infection and the pharmacological action of this regimen.

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA_1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA_1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

Under the background of the comprehensively implementing the rule of law, the construction of legal practice of medical institutions in China is directly related to the sustainable and high-quality development of the medical service industry. However, at present, each medical institution lacked a systematic plan for the construction of legal practice, and the health administrative department mostly implemented the measures of inspection and punishment for illegal practice, which led to the situation that the illegal practice of medical institutions was " investigated but not corrected, and changed but invalid" . This paper creatively put forward the application research of administrative reconciliation theory in the legal practice management of medical and health institutions, for promoting medical and health institutions and medical staff to strengthen legal practice management, standardizing medical behavior, ensuring medical safety, and achieving high-quality development through the institutional incentive and guidance.
