Objective:To investigate the epidemic trend and risk change of acquired immunodeficiency syndrome (AIDS) complicated with malignant tumors after combination antiretroviral therapy (cART).Methods:The types of malignant tumors in patients with AIDS at different stages of cART were analyzed among anti-human immunodeficiency virus (HIV)-positive population in Hubei Province screened in National AIDS/HIV prevention and control information system from 1st January, 2004 to 31st December, 2018. The standardized incidence ratios(SIR) of malignant tumors in AIDS patients was analyzed based on the incidence of malignant tumors in the general population in Hubei Province or China in 2013. The changes in risks for development of malignant tumors in AIDS patients at different cART stages from 2004 to 2013 and 2014 to 2018 were compared.Chi-square test was used for statistical analysis.Results:Three hundred and twenty-three out of 22 994 AIDS patients were diagnosed with malignant tumors. Non-Hodgkin lymphoma(NHL) and cervical cancer were most common types in acquired immunodeficiency syndrome-defining cancers (ADC), while liver cancers and lung cancers were the most common types in non-acquired immunodeficiency syndrome-defining cancers (NADC). The overall risk of malignancy in AIDS patients was similar to that in the general population (SIR=1.06, χ2=0.62, P=0.426). However, the risks of Kaposi sarcoma, NHL, Hodgkin lymphoma, cervical cancer, and head and face cancers (excepting nasopharyngeal cancer) in AIDS patients were significantly higher than those in the general population (SIR=834.09, 9.65, 13.33, 5.22 and 2.94, respectively, χ2=11 747.27, 625.54, 56.65, 184.21 and 13.66, respectively, all P<0.01). The risks of lung cancer, colorectal anal cancer, stomach cancer and breast cancer in AIDS patients were significantly lower than those in the general population (SIR=0.33, 0.36, 0.43 and 0.45, respectively, χ2=33.43, 12.84, 9.01 and 7.21, respectively, all P<0.05). The SIR of cervical cancer, liver cancer and colorectal anal cancer from 2014 to 2018 were 4.06, 0.43 and 0.10, respectively, which were significantly lower than those from 2004 to 2013 (7.42, 1.96 and 0.84, respectively). The differences were all statistically significant ( χ2=5.39, 19.52 and 10.86, respectively, all P<0.05). Conclusions:At present, there are no significant differences of the incidences of malignant tumors between AIDS patients and general population, but the tumor types are different. The most common malignant tumors in this region are NHL and cervical cancer, which should be noted that HIV screening among patients with such tumors is conducive to comprehensive treatment to improve the efficacy.

Objective:To investigate the relationship between positive rate and titer of hepatitis B surface antibody (anti-HBs) and CD4 + T lymphocyte count level in human immunodeficiency virus (HIV) infected patients after hepatitis B virus (HBV) exposure. Methods:A total of 4 893 HIV-infected patients were admitted to Zhongnan Hospital of Wuhan University from January 2010 to December 2018. The demographic data, HIV-related diagnosis, treatment information, CD4 + T lymphocyte count and serum markers of HBV infection of HIV infected patients were retrospectively analyzed. The patients were grouped according to the CD4 + T lymphocyte count and serum markers of HBV infection, and the differences of anti-HBs positive rate and HBV exposure rate in patients with different CD4 + T lymphocyte counts were compared.The differences of CD4 + T lymphocyte count in patients with different titer of anti-HBs were compared. Statistical analysis was performed using chi-square test, analysis of variance or t test. Results:Patients with HIV infection were divided into CD4 + T lymphocyte count<200/μL group (3 293 cases), 200-500/μL group (1 200 cases) and CD4 + T lymphocyte count>500/μL group (400 cases). The HBV exposure rates in the three groups were 78.0%(2 569/3 293), 77.0%(924/1 200) and 76.2%(305/400), respectively. The anti-HBs positive rates were 38.2%(1 258/3 293), 53.8%(645/1 200) and 62.5%(250/400), respectively. The anti-HBs titers were (120.00±36.45) IU/L, (148.00±26.40) IU/L and (212.00±92.08) IU/L, respectively. The exposure rates of HBV in the three groups were similar ( χ2=0.992, P=0.609), but the positive rates and titers of anti-HBs were significantly different ( χ2=146.779 and F=45.362, respectively, both P<0.01). When the patients were grouped by anti-HBs titer, 2 740 cases were divided into anti-HBs negative group (<10 IU/L), 1 220 cases in low anti-HBs group (10-99 IU/L), 693 cases in medium anti-HBs group (100-499 IU/L) and 240 cases in high anti-HBs group (≥500 IU/L). The CD4 + T lymphocyte count levels of the four groups were (150.00±8.42)/μL, (185.00±7.08)/μL, (243.00±12.07)/μL and (308.00±22.60)/μL, respectively. The overall CD4 + T lymphocyte count levels among the four groups were significantly different ( F=68.479, P<0.01). Among the 90 HIV infected patients who received anti-retroviral therapy (ART), the anti-HBs titer increased from (91.96±21.87) IU/L to (200.76±56.43) IU/L after treatment, and the anti-HBs level before and after treatment was significantly different ( t=-2.542, P=0.035). Among 208 patients with negative HBV markers, no patients had hepatitis B surface antigen switched to positive when monitored for an interval time of (26.2±5.3) months. Conclusions:The risk of HBV exposure in patients with HIV infection is not significantly related to the disease stage, but the positive rate and titer of anti-HBs are significantly positively correlated with CD4 + T lymphocyte count level. The monitoring of anti-HBs and the serum markers of HBV infection in the same individual is conducive to the in-depth understanding of the protective effect of anti-HBs and the scientific evaluation of the risk of infection after HBV exposure.

Objective:To investigate the risk factors associated with death among patients with coronavirus disease 2019 (COVID-19).Methods:A total of 217 COVID-19 patients admitted to Zhongnan Hospital, Wuhan University from December 29, 2019 to January 31, 2020 were enrolled. The general conditions, clinical symptoms, comorbidities, laboratory test indicators and clinical outcomes of the COVID-19 patients were analyzed. According to prognosis, the COVID-19 patients were divided into the death group and the survival group, and the clinical manifestations and laboratory examination results of the two groups were compared by t test and chi-square test. The binary logistics regression model was used to analyze the risk factors related to death. Results:Among the 217 COVID-19 cases, 124 were males and 93 were females, as of March 4, 2020, 25 died and 192 survived, with the mortality of 11.5%. Eighty-nine patients (41.0%) had confirmed history of exposure to the Huanan seafood market or had close contact with another patient with confirmed COVID-19. Among the patients who died, 21(84.0%) were male, 21(84.0%) had comorbidities, 15(60.0%) had more than three types of clinical symptoms, 14(56.0%) had alaine aminotransferase or aspartate aminotransferase>1.5 upper limit of normal (ULN), 13(52.0%) had creatinine (Cr) >104 μmol/L, and 18(72.0%) had procalcitonin (PCT) >0.05 μg/L, whereas the above indicators among the survival patients were 103(53.6%), 95(49.5%), 92(47.9%), 23(12.0%), 14(7.3%) and 47(24.5%), respectively. The differences of the above indicators between the two groups were all statistically significant ( χ2=11.506, 7.889, 14.897, 30.307, 40.585 and 23.807, respectively, all P<0.01). The multivariate analysis results showed that age≥65 years old (odds ratio ( OR)=5.968, 95% confidence interval ( CI)1.991-17.888, P=0.001), male ( OR=6.009, 95% CI 2.504-14.422, P<0.01), comorbidities ( OR=7.152, 95% CI 2.058-24.851, P=0.002), having more than three types of clinical symptoms ( OR=7.944, 95% CI 2.280-27.676, P=0.001), alanine aminotransferase or aspartate aminotransferase>1.5×ULN ( OR=9.552, 95% CI 3.760-24.269, P<0.01), Cr>104 μmol/L ( OR=11.458, 95% CI 4.289-30.613, P<0.01), lactic acid dehydrogenase (LDH)>243 U/L ( OR=7.591, 95% CI 1.683-34.249, P=0.008) and PCT>0.05 μg/L( OR=12.410, 95% CI 4.433-34.744, P<0.01) were risk factors for death among COVID-19 infection patients. Conclusion:For elderly male COVID-19 patients with comorbidities, impaired liver and kidney functions, elevated LDH and PCT are early warning signs for disease deterioration.

The data of patients with HIV/AIDS from Hubei Province during 2004 to 2018 were obtained from the National AIDS Comprehensive Prevention and Control Information System. A total of 22 980 HIV-positive or AIDS patients were followed up for 113 164 person-years and 323 malignant tumors were diagnosed. Non-Hodgkin′s lymphoma (NHL), cervical cancer, liver cancer, lung cancer, and Kaposi sarcoma (KS) accounted for 70.0% (226/323) of all malignant tumors in this population. The average crude incidence and mortality of malignant tumors in HIV-infected patients were 285.43/100 000(269.11/100 000 in males and 325.87/100 000 in females), and 169.67/100 000(184.78/100 000 in males and 132.19/100 000 in females), respectively. The result indicates that the overall cancer incidence and mortality in HIV/AIDS population under widely implementation of combination anti-retroviral therapy (cART) are similar to those in the general population of the region. But the incidence and mortality of AIDS-related tumors such as KS, NHL, HD and cervical cancer are higher than those in general population, and attention should be given to screening of these malignancies in HIV/AIDS population.

Objective: To analysis the manifestations of chest CT imaging in acquired immunodeficiency syndrome (AIDS) patients complicated with pulmonary cryptococcosis. Methods: The clinical data of 72 AIDS patients complicated with pulmonary cryptococcosis were analyzed retrospectively. There were 3 cases (4.2%) diagnosed with pulmonary cryptococcosis by biopsy, including 1 case of pulmonary cryptococcosis and 2 cases of disseminated cryptococcosis; 69 cases (95.8%) with pulmonary manifestations and clinically diagnosed with pulmonary cryptococcosis, including 43 cases of cryptococcal meningitis and 26 cases of disseminated cryptococcosis. The imaging features of chest CT, in terms of the morphology, size, number, distribution, internal features and margins of the lesions were analyzed. Results: The chest CT findings were solid nodules or mass in 49 cases (68.1%), patchy shadows in 40 cases (55.6%), cavitary nodules or mass in 10 cases (13.9%), mediastinal and hilar lymph node enlargement in 17 cases (23.6%) and pleural effusion in 10 cases (13.9%). Conclusion The chest CT findings of AIDS patients complicated with pulmonary cryptococcosis mainly are multiple solid nodules or masses, patchy shadows and solitary cavitary pulmonary nodules or mass. For early diagnosis and treatment, cryptococcus screening should be performed in HIV-infected patients with pulmonary nodules or mass on chest CT.

Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.

OBJECTIVETo investigate the incidence of hepatotoxicity in acquired immunodeficiency syndrome (AIDS) patients on combined anti-retroviral therapy (cART) containing nevirapine (NVP) and to assess the risk factors and its impact on cART.

METHODS330 AIDS patients from March 2003 to June 2008 at local county were enrolled and a retrospective study using Kaplan-meier survival and Multivariate logistic regression modeling was conducted.

RESULTS267 out of 330 patients received NVP based cART and 63 cases received EFV-based cART. The deference of prevalences of hepatotoxicity between the two groups is statistically significant (Chi2 = 6.691, P = 0.01). 133 out of 267 (49.8%) patients on NVP based cART had at least one episode of ALT elevation during a median 21 months (interquartile ranges, IQR 6, 37) follow-up time, amounts for 28.5 cases per 100 person-years. Baseline ALT elevation (OR = 14.368, P = 0.017)and HCV co-infection (OR = 3.009, P = 0.000) were risk factors for cART related hepatotoxicity, while greatly increased CD4+ T(CD4) cell count was protective against hepatotoxicity development (OR = 0.996, P = 0.000). Patients co-infected with HCV received NVP-based cART had the higher probability of hepatotoxicity than those without HCV co-infection (Log rank: Chi2 = 16.764, P = 0.000). 23 out of the 133 subjects (17.3%) with NVP related hepatotoxicity discontinued cART temporarily or shifted NVP to efavirenz.

CONCLUSIONNVP related hepatotoxicity was common among ARV naive HIV infected subjects in our cohort. Baseline ALT elevation and HCV co-infection were associated statistically with the development of hepatotoxicity. Hepatotoxicity led to discontinuing cART temporarily or switching to other regimens in some subjects. It suggested that NVP should be used with caution in patients co-infected with HCV among whom anti-HCV therapy before cART initiation may contribute to minimizing the probability of NVP associated hepatotoxicity.

OBJECTIVESalt-sensitivity plays an important role in essential hypertension and is associated with more severe target organ injury and higher mortality in patients with essential hypertension. However, the pathologic mechanism of salt-sensitivity is poorly understood and endothelial dysfunction might be involved in salt-sensitive hypertension. We, therefore, observed the endothelial function changes by measuring plasma and urine nitric oxide (NO) concentrations in salt-sensitive (SS) normotensive and mild hypertensive subjects underwent various salt loading protocols and the effects of potassium supplement.

METHODSThirty-nine normotensive and mild hypertensive subjects (< 160/100 mm Hg), aged 16-60, were enrolled and the study protocol is as follows: 3 days baseline investigation, 1 week low-salt loading (3 g/day), 1 week. high-salt loading (18 g/day) and 1 week high-salt loading plus potassium chloride (4.5 g/day).

RESULTSPlasma and urine NO levels were significantly lower in SS (n = 8) subjects at baseline, low-salt and high-salt loading phases compared with salt-resistant subjects (SR, n = 31) and oral potassium supplement to SS subjects with high salt loading significantly increased plasma and urine NO levels.

CONCLUSIONEndothelial function is impaired in normotensive and mild hypertensive SS subjects. Oral potassium supplement could improve endothelial function in normotensive and mild hypertensive SS subjects.
