Clinical outcomes of people living with human immunodeficiency virus (HIV) with diffuse large B-cell lymphoma (DLBCL) in Shanghai, China / 中华医学杂志(英文版)

BACKGROUND@#Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).@*METHODS@#A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple regression model was constructed to identify related factors for OS.@*RESULTS@#A total of 54 eligible patients were included in the final analysis with a median follow-up of 14 months (interquartile range [IQR]: 8-29 months). The proportion of high international prognostic index (IPI) patients was much larger in the DA-EPOCH-R group (n = 29) than that in the R-CHOP group (n = 25). The CD4 cell counts and HIV RNA levels were not significantly different between the two groups. The 2-year OS for all patients was 73%. However, OS was not significantly different between the two groups, with a 2-year OS rate of 78% for the DA-EPOCH-R group and 66% for the R-CHOP group. Only an IPI greater than 3 was associated with a decrease in OS, with a hazard ratio of 5.0. The occurrence of grade 3 and 4 adverse events of chemotherapy was not significantly different between the two groups.@*CONCLUSIONS@#Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.

Clinical features and treatment outcomes of human immunodeficiency virus-associated cryptococcal meningitis: a 2-year retrospective analysis / 中华医学杂志(英文版)

BACKGROUND@#Cryptococcal meningitis (CM) is one of the most common opportunistic infections caused by Cryptococcus neoformans in human immunodeficiency virus (HIV)-infected patients, and is complicated with significant morbidity and mortality. This study retrospectively analyzed the clinical features, characteristics, treatment, and outcomes of first-diagnosed HIV-associated CM after 2-years of follow-up.@*METHODS@#Data from all patients (n = 101) of HIV-associated CM hospitalized in Shanghai Public Health Clinical Center from September 2013 to December 2016 were collected and analyzed using logistic regression to identify clinical and microbiological factors associated with mortality.@*RESULTS@#Of the 101 patients, 86/99 (86.9%) of patients had CD4 count <50 cells/mm, 57/101 (56.4%) were diagnosed at ≥14 days from the onset to diagnosis, 42/99 (42.4%) had normal cerebrospinal fluid (CSF) cell counts and biochemical examination, 30/101 (29.7%) had concomitant Pneumocystis (carinii) jiroveci pneumonia (PCP) on admission and 37/92 (40.2%) were complicated with cryptococcal pneumonia, 50/74 (67.6%) had abnormalities shown on intracranial imaging, amongst whom 24/50 (48.0%) had more than one lesion. The median time to negative CSF Indian ink staining was 8.50 months (interquartile range, 3.25-12.00 months). Patients who initiated antiretroviral therapy (ART) before admission had a shorter time to negative CSF Indian ink compared with ART-naïve patients (7 vs. 12 months, χ = 15.53, P < 0.001). All-cause mortality at 2 weeks, 8 weeks, and 2 years was 10.1% (10/99), 18.9% (18/95), and 20.7% (19/92), respectively. Coinfection with PCP on admission (adjusted odds ratio [AOR], 3.933; 95% confidence interval [CI], 1.166-13.269, P = 0.027) and altered mental status (AOR, 9.574; 95% CI, 2.548-35.974, P = 0.001) were associated with higher mortality at 8 weeks.@*CONCLUSION@#This study described the clinical features and outcomes of first diagnosed HIV-associated CM with 2-year follow-up data. Altered mental status and coinfection with PCP predicted mortality in HIV-associated CM.

Epidemiological and clinical features of occult hepatitis B in HIV infection without antiretroviral treatment / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate and analyze the differential prevalence, as well as the risk factors and clinical features, of occult hepatitis B virus (HBV) infection in the human immunodeficiency virus (HIV)-infected population without antiretroviral therapy (ART) as compared to the general (non-HIV-infected) population.</p><p><b>METHODS</b>Two-hundred-and-forty-eight individuals with confirmed HIV infection but ART naive (males: 220, females: 28; 15-82 years old) were enrolled in the study, along with 121 healthy individuals (confirmed HIV antibody-negative; males: 53, females: 68; 20-88 years old). HBV markers (hepatitis B surface antigen (HBsAg); hepatitis B e antigen (HBeAg); anti-HBs, anti-HBe and anti-hepatitis B core (HBc) antibodies) were detected by microparticle enzyme-linked immunosorbent assay (AxSYM immunology analyzer manufactured by Abbott Laboratories); all cases and controls were confirmed negative for hepatitis B surface antigen (HBsAg). Then, the HBV DNA level in serum was detected using nucleic acid amplification assay (COBAS AmpliPrep/COBAS TaqMan HBV test, version 2.0 manufactured by Roche). CD4+ T lymphocytes were measured by flow cytometry, and alanine aminotransferase (ALT, marker of liver function) was measured by enzymatic assay.</p><p><b>RESULTS</b>Twenty-four of the HIV cases (9.7%) and four of the healthy controls (3.3%) tested positive for HBV DNA; the amount of individuals with HBV DNA-positivity was significantly higher in the HIV-infected group (P = 0.035). Among the 24 cases of HBV DNA(+) HIV-infected individuals, the lowest HBV DNA load was < 20 IU/ml and the highest was 3.22 x 10s IU/ml; nine of the individuals (37.5%) had HBV DNA load > 100 IU/ml, four (16.7%) had 20-99 IU/ ml, and 11 (45.8%) had < 20 IU/ml. Among the total HIV-infected cases with HBV DNA-positivity, 7.3% (8/110) were anti-HBc(+)/anti-HBs(+), 20.8% (11/53) were anti-HBc(+)/anti-HBs(-), 14.3% (3/21) were anti-HBc(-)/anti-HBs(+), and 3.1% (2/64) were anti-HBc(-)/anti-HBs(-). The amount of individuals with HBV DNA-positivity in the anti-HBc(+)/anti-HBs(-) group was significantly different from those in the anti-HBc(+)/anti-HBs(+) group (P = 0.018) and the anti-HBc(-)/anti-HBs(-) group (P = 0.003). However, multiple comparison of HBV DNA loads detected between the four groups of HBV marker status revealed no significant difference (P = 0.805). Furthermore, statistical analysis provided no evidence to support that occult hepatitis B infection in HIV-infected individuals had any impact on CD4+ T lymphocytes count (Z = 1.902, P = 0.059) or ALT levels (Z =1.401, P = 0.161).</p><p><b>CONCLUSION</b>HIV-infected individuals who are ART naive and HBsAg(-) have a higher incidence of HBV DNA-positivity than individuals in the general (non-HIV-infected) population. In addition, the highest rate of occult hepatitis B among the HIV-infected cases occurred among individuals who were anti-HBc(+)/anti-HBs(-).</p>

Sixty-two severe and critical patients with 2009 influenza A (H1N1) in Shanghai, China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Pandemic influenza A (H1N1) emerged rapidly in China in May 2009. Preliminary comparisons with seasonal influenza suggest that pandemic 2009 influenza A (H1N1) disproportionately affects younger ages and causes generally mild disease. To characterize disease progress, comorbidities, and treatment outcomes among consecutive severe and critically ill patients in a hospital served as a reference center for the care of patients with H1N1 in Shanghai, China.</p><p><b>METHODS</b>A retrospective study on 62 severe and critically ill patients with 2009 influenza A (H1N1) was conducted in Shanghai Public Health Clinical Center. Demographic data, symptoms, comorbidities, disease progression, treatments, and clinical outcomes were collected for analysis.</p><p><b>RESULTS</b>Sixty-two severe or critically ill patients were admitted to the hospital with confirmed 2009 influenza A (H1N1) infection. The median age of the study cohort was 40 years old with a range from 18 years to 75 years, and 67.7% were males. All patients presented with fever and respiratory symptoms. At presentation, 34 patients (54.8%) had comorbidities such as smoking (29.0%), hypertension (29.0%) and hepatitis B virus infection (9.7%). The median time from symptom onset to hospital admission was 6 days (interquartile-range 3 - 14 days) and 23 critically ill patients were admitted to Intensive Care Unit after admission. All the patients received neuraminidase inhibitors (oseltaminir), while 60 patients (96.7%) were treated with antibiotics, and 39 (62.9%) with corticosteroids. Twenty-three critical cases received noninvasive mechanical ventilation on the first day of admission, and 3 of them ultimately required invasive ventilation. Four death reports (6.5%) were filed within the first 14 days from the onset of critical illness with the primary causes of severe acute respiratory distress syndrome, hypoxemia, or complications, secondary infection and sepsis, pyopneumothorax and stroke.</p><p><b>CONCLUSIONS</b>Severe illness from 2009 influenza A (H1N1) infection in Shanghai occurred among young individuals. Critical cases were associated with severe hypoxemia, multisystem organ failure, and a requirement for mechanical ventilation. Most patients had a good prognosis.</p>

Peg-interferon alfa-2a and highly active antiretroviral drug therapy on hepatitis C patients with AIDS / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To evaluate the clinical effect and side-effect of peg-interferon alfa-2a (PEG-IFN alfa-2a) and highly active antiretroviral therapy (HAART) for patients infected with hepatitis C virus (HCV) and co-infected with human immunodeficiency virus (HIV).</p><p><b>METHODS</b>Twenty-two patients with HCV/HIV co-infection received highly active antiretroviral therapy initially; after their CD4 lymphocyte counts rose to over 0.20x10(9)/L, they were separated into two groups: one group with CD4 lymphocytes over 0.35x10(9)/L (high group) and one group with CD4 lymphocytes below 0.35x10(9)/L (low group). Both groups were given 180 microg of PEG-IFN alfa-2a every week intramuscularly. HCV RNA and HIV RNA loads, blood cell and CD4 lymphocyte counts, and liver functions were routinely examined.</p><p><b>RESULTS</b>After 12, 24 and 48 weeks of PEG-IFN alfa-2a therapy, mean HCV RNA loads reduced 2.0650 log10 copies/ml (t=3.8733), 2.9146 log10 copies/ml (t=7.6741) and 2.4315 log10 copies/ml (t=5.8202) from the baseline at week 0 in the 13 patients in the high group, and reduced 1.1522 log10 copies/ml (t = 2.8937), 1.4189 log10 copies/ml (t=2.4422) and 1.1167 log10 (t=1.1261) in the 8 patients of the low group. However, there was no significant difference between the early viral response rate (EVR) and the end of treatment viral response rate (ETVR) of the two groups. In the high group, the white blood cell count was lower at 24 weeks than the base line (t=2.4700), and the blood platelet count was lower both at 24 and 48 weeks than the base line (t=2.3273 and t=3.6149).</p><p><b>CONCLUSIONS</b>PEG-IFN alfa-2a can effectively reduce HCV RNA loads in patients with HCV-/HIV co-infection, and the inhibition rate in patients with higher CD4 lymphocyte counts is better. The EVR and ETVR of the two groups of patients show similar results after the treatment. PEG-IFN alfa-2a can reduce the white blood cell counts and the blood platelet counts in the peripheral blood.</p>
