Human immune deficiency virus (HIV) is a leading cause of death. It attacks the immune system, thereby rendering the infected host susceptible to many HIV-associated infections, malignancies and neurocognitive disorders. The altered immune system affects the way the human host responds to disease, resulting in atypical presentation of these disorders. This presents a diagnostic challenge and the clinician must use all diagnostic avenues available to diagnose and manage these conditions. The advent of highly active antiretroviral therapy (HAART) has markedly reduced the mortality associated with HIVinfection but has also brought in its wake problems associated with adverse effects or drug interaction and may even modulate some of the HIV-associated disorders to the detriment of the infected human host. Nuclear medicine techniques allow non-invasive visualisation of tissues in the body. By using this principle, pathophysiology in the body can be targeted and the treatment of diseases can be monitored. Being a functional imaging modality, it is able to detect diseases at the molecular level, and thus it has increased our understanding of the immunological changes in the infected host at different stages of the HIV infection. It also detects pathological changes much earlier than conventional imaging based on anatomical changes. This is important in the immunocompromised host as in some of the associated disorders a delay in diagnosis may have dire consequences. Nuclear medicine has played a huge role in the management of many HIV-associated disorders in the past and continues to help in the diagnosis, prognosis, staging, monitoring and assessing the response to treatment of many HIV-associated disorders. As our understanding of the molecular basis of disease increases nuclear medicine is poised to play an even greater role. In this review we highlight the functional basis of the clinicopathological correlation of HIV from a metabolic view and discuss how the use of nuclear medicine techniques, with particular emphasis of F-18 fluorodeoxyglucose, may have impact in the setting of HIV. We also provide an overview of the role of nuclear medicine techniques in the management of HIV-associated disorders.

OBJECTIVETo investigate the mortality of HIV infected clients from methadone maintenance treatment (MMT) clinics in Yili Kazakh autonomous prefecture as well as the factors associated with mortality of HIV infected clients.
METHODSA retrospective cohort study was performed. Data of 860 cases were collected from National Methadone Maintenance Treatment database, National AIDS/HIV database and antiretroviral therapy (ART) treatment database for adults. Information collected included demographic information of HIV infected clients, methadone daily treatment information, CD4 testing information, ART treatment information and death information. Recruiting began from August, 2005 through May, 2011. Cox proportional regression was used to identify factors associated with mortality. The proportional hazard assumption was assessed using Schoenfeld's residuals test. Missing values were imputed using the multiple linear regression method. R software (version 2.13.0) was used to perform data analysis.
RESULTSA total of 860 HIV positive MMT clients were analyzed. The methadone dose for study subjects was (38.2 ± 20.7) mg/d. 27.8% (239/860) of study subjects participated in ART treatment, 38.7% (333/860) had never tested for CD4 count. The age for study subjects was (32.9 ± 6.4) years old. Among all these subjects, 67.3% (579/860) were married. During the observation period, 151 deaths were observed in 2192.9 person years. The average observation time was 2.6 year for each subject. The all-cause mortality rate was 68.9‰. Cox proportion model showed that ART treatment (HR = 0.53, 95%CI: 0.32 - 0.88), baseline CD4 count at 200 - 350 cells/µl (HR = 0.35, 95%CI: 0.20 - 0.60), baseline CD4 count more than 350 cells/µl (HR = 0.16, 95%CI: 0.09 - 0.29), and marriage (HR = 0.55, 95%CI: 0.37 - 0.82) were associated with less mortality compared with control group. Age (more than 45 years old) (HR = 5.20, 95%CI: 2.60 - 10.20) and sharing needles (HR = 1.40, 95%CI: 1.02 - 2.00) were risk factors associated with death.
CONCLUSIONHigh mortality rate was observed among HIV infected clients. Methadone clinic should provide ART treatment or ART referral services.

BACKGROUNDMorbidity and mortality of advanced human immunodeficiency virus infection (HIV) have declined in Western industrialized countries since the availability of highly active antiretroviral therapy (HAART). It is unclear if this has also happened in Hong Kong.
METHODSWe studied a retrospective cohort of patients with advanced HIV disease in Hong Kong, China. First, the mortality of advanced HIV disease per year was calculated for the decade 1993 to 2002, both annually and according to patient observation before and after 1997. Second, the event rates were estimated for the clinical end points of acquired immune deficiency syndrome (AIDS) and death. Univariate and multivariate analyses were then performed to identify associated factors.
RESULTSThe crude mortality of advanced HIV disease declined from 10.8-30.4 per 100 patients during 1993-1996, to 0.8-6.9 per 100 patients during 1997-2002. A rate ratio of 4.04 (95% CI, 2.52-6.47) was evident for those observed in 1993-1996, compared to those in 1997-2002. In a multivariate analysis where calendar period was adjusted, use of highly active antiretroviral therapy was associated with rate ratios of 0.13 (95% CI, 0.05-0.33) for death after AIDS, 0.08 (95% CI, 0.04-0.19) for AIDS after a CD4 cell count < 200/microl, and 0.21 (95% CI, 0.07-0.67) for death after CD4 cell count < 200/microl. In the same analysis, calendar period ceased to be a significant factor after adjustment for use of HAART.
CONCLUSIONSThe mortality and morbidity of advanced human immunodeficiency virus disease have declined in Hong Kong. This improved prognosis was attributable to the use of highly active antiretroviral therapy.

OBJECTIVETo observe the effect of Chinese medicine and pharmacy (CMP) on the mortality of senile HIV/AIDS patients as adjunctive therapy.
METHODSHIV/AIDS patients of a certain rural area of Hanna Province, who were recruited in national CMP HIV treatment trial program (NTCMTP) in 2004, were enrolled as the CMP treatment group. HIV/AIDS patients in the same village without recruiting in NTCMTP were enrolled as the non-CMP treatment group. Data related to subjects were collected from the database of NTCMTP and National HAART Reporting System. Multiple regression analysis under Cox proportional hazard model was applied to examine the risk factors for death of senile HIV/AIDS patients.
RESULTSA total of 436 HIV/AIDS were enrolled in this study, 204 in the CMP treatment group and 232 in the non-CMP treatment group. There were 70 AIDS-relative deaths in the CMP treatment group, with 8-year mortality rate of 37.74%. There were 111 AIDS-relative deaths in the non-CMP treatment group, with 8-year mortality rate of 48.34%. The 8-year mortality rate was higher in the non-CMP treatment group than in the CMP treatment group (chi2 = 5.136, P < 0.05). Results of univariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.41 times that of the CMP treatment group (P < 0.05). Result of multivariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.44 times that of the CMP treatment group (P < 0.05). Besides, gender and marital conditions were significantly associated with death of HIV/AIDS patients.
CONCLUSIONCMP treatment was favorable to lower the mortality rate of senile HIV/AIDS patients, and its objective evaluation awaits for further prospective study.

Although a decrease in acquired immunodeficiency syndrome (AIDS)-related mortality has been documented in highly active antiretroviral therapy (HAART) era, there are no published data comparing specific causes of death between pre-HAART and HAART era in Korea. Mortality and cause of death were analyzed in three treatment periods; pre-HAART (1990-1997), early-HAART (1998-2001), and late-HAART period (2002-2011). The patients were retrospectively classified according to the treatment period in which they were recruited. Although mortality rate per 100 person-year declined from 8.7 in pre-HAART to 4.9 in late-HAART period, the proportion of deaths within 3 months of initial visit to study hospital significantly increased from 15.9% in pre-HAART to 55.1% in late-HAART period (P < 0.001). Overall, 59% of deaths were attributable to AIDS-related conditions, and Pneumocystis pneumonia (PCP) was the most common cause of death (20.3%). The proportion of PCP as cause of death significantly increased from 8.7% in pre-HAART to 31.8% in late-HAART period (P < 0.001). Despite of significant improvement of survival, there was still a high risk of early death in patients presenting in HAART era, mainly due to late human immunodeficiency virus (HIV) diagnosis and late presentation to care.

Objective: To understand the survival of HIV/AIDS patients after receiving antiretroviral therapy for 10 year in Henan province and related factors. Methods: The database of national integrated management system of HIV/AIDS was used to collect the basic information and follow-up information of HIV/AIDS patients who received antiretroviral therapy between 2003 and 2005 in Henan province. Software SPSS 23.0 was used to analyze the patients' survival and related factors based on the life-table method and Cox proportional hazards model. Results: Among the 2 448 HIV/AIDS patients who started antiretroviral therapy during 2003-2005, the men accounted for 53.5%, and women accounted for 46.5%. Up to 70.1% of the patients were aged 40-59 years and 95.5% of the patients had blood borne infections. The patients were observed for 10 years after antiviral treatment, and 719 cases died from AIDS related diseases, with a mortality rate of 3.78/100 per year (719/19 010 per year). The cumulative survival rates of patients within 1-year, 3 years, 5 years and 10 years were 0.94, 0.86, 0.78, 0.69 respectively. Compared with the patients aged <40 years, the HRs of the patients aged 40-, 50-, 60- and ≥70 years were 1.417 (95%CI: 0.903-2.222), 1.834 (95%CI: 1.174-2.866), 2.422 (95%CI: 1.539-3.810) and 3.424 (95%CI: 2.053-5.709) respectively. Compared with patients with baseline CD(4+)T lymphocyte >350 unit/ul, the HRs of the patients with CD(4+)T lymphocyte <50 unit/μl, 50-199 unit/ul and 200-350 unit/ul were 7.105 (95%CI: 5.449-9.264), 4.175 (95%CI: 3.249-5.366) and 2.214 (95%CI: 1.691-2.900) respectively. Compared with the women, the HR of the men was 1.480 (95%CI: 1.273-1.172). Compared with the patients who received second line ART therapy, the HR of patients receiving no second line therapy was 11.923 (95%CI: 9.410-15.104). Conclusions: The cumulative survival rate the HIV/AIDS patients after 10 years of antiretroviral therapy reached 0.69 in Henan. Male, old age, low basic CD(4+)T lymphocyte count and receiving no second line therapy were the risk factors for long-term survival of AIDS patients.

INTRODUCTIONHighly active antiretroviral therapy (HAART) has greatly changed the epidemiology of human immunodefi ciency virus (HIV) mortality. The aim of this study is to compare the causes of death and factors associated with early death in HIV-infected persons in the pre- and peri-highly active antiretroviral therapy (HAART) periods.
MATERIALS AND METHODSWe conducted a retrospective review of 483 HIV-infected persons who were diagnosed with HIV from 1985 to 2000, and had died within 5 years of the diagnosis. We examined the temporal change in the primary causes of death between those who were diagnosed in the pre-HAART (1985 to 1995) and peri-HAART (1996 to 2000) periods, and compared the demographic and clinical characteristics of the 2 groups.
RESULTSDuring the peri-HAART period, HIV encephalopathy, cryptococcal meningitis, and lymphoma were no longer the leading causes of death. Opportunistic infections remained important causes of death. Early deaths from the peri-HAART period were older (60 years and above) at diagnosis (Adj OR 7.50; 95% CI, 1.78 to 31.58), more likely to be divorced (Adj OR 5.05, 95% CI, 1.96 to 13.02) and tended to have a low baseline CD4 cell count of <50 cells/ uL (Adj OR 2.18, 95% CI, 1.14 to 4.16) , and were more likely to have received HAART (Adj OR 5.19; 95% CI, 2.22 to 12.12) than early deaths from the pre-HAART period.
CONCLUSIONIn the peri-HAART era, HIV-infected persons who died within 5 years of diagnosis were those who were older (≥60 years), divorced, or who presented with very late-stage disease (CD4 <50) at diagnosis. More targeted public health interventions, such as targeted public health messages and outreach to increase access to HIV testing and treatment should be developed for these subpopulations.

Chinese Journal of Lung Cancer 2018;21(4):327-332
BACKGROUND:
To observe clinical features, clinical stagings, types ofpathology, treatment options and clinical effects of patients suffer from HIV infection combined with lung cancer, and also to provide guidance for individualized comprehensive treatment of HIV combined with lung cancer.
METHODS:
Through the retrospective analysis of 53 cases of HIV merger of lung cancer patients admitted in our department, 47 cases of non-small cell lung cancer (NSCLC), 6 cases of small cell lung cancer (SCLC), 24 cases accepted surgery combined chemotherapy, 22 patients with simple chemotherapy, 7 cases give up treatment; 28 cases are in stages I-III, 25 cases are in stage IV; 24 patients received combined chemotherapy in 28 patients with stages I-III, 2 cases gave up treatment, 2 cases with severe chronic obstructive pulmonary disease (COPD) could not tolerate chemotherapy plus surgery. According to the situation of patients before highly active anti-retroviral therapy (HAART) treatment, patients who received HAART before treatment were divided into observation group (n=27), patients who did not receive HAART were divided into control group (n=19). The survival and the independent influencing factors between the two groups were analyzed.
RESULTS:
Among the 53 HIV infected cases a toal of 46 patients received treatment among 53 cases of treatment in patients with lung cancer merger of HIV, there are no differences of 1 year survival rate, 2 years survival rate between observation group and control group; patients in I-III phase 1 year survival rate was 76.0%, 2 years survival rate was 60.0%. Patients in IV phase 1 year survival rate was 13.6%, 2 years survival rate was 0%. 24 patients with surgery combined chemotherapy 1 year survival rate was 83.3%, 2 years survival rate was 62.5%; 22 cases treated with simple chemotherapy 1 year survival rate was 18.0%, 2 years survival rate was 0%.
CONCLUSIONS
HIV merger in patients with lung cancer can improve the patients survival rate after different individualized comprehensive treatment, early surgery with combined chemotherapy has remarkable effect.

A retrospective review of 4,721 human immunodeficiency virus (HIV)-infected patients, followed at St. Luke's Roosevelt Hospital Center, New York City, was conducted from January 1, 2005 to December 31, 2009. HIV-Hepatitis B virus (HBV) co-infection rate was 218/4,721, 4.6%. Among co-infected patients, 19 patients (19/218, 8.7%) died; 13 patients (13/19, 68.4%) died from non-acquired immune deficiency syndrome (AIDS) defining including 2 patients with liver failure. More non-survivors (5 patients, 5/19, 26.3%) had liver cirrhosis than those who survived (8 patients, 8/199, 4.0%; P = 0.002). There were more patients with positive HBV e antigen (HBeAg) among non-survivors, (12 patients, 12/19, 63.2%) than among survivors (74 patients, 74/199, 37.2%; P = 0.047). HIV-HBV co-infection is associated with increased overall mortality. Therefore, use of dual active antiretrovirals, particularly, tenofovir (TDF) based regimen for optimal suppression of HIV-HBV and immune restoration with prevention of high risk behaviors may contribute to improved outcomes.

A retrospective study was conducted to determine the mortality, causes and risk factors for death among HIV-infected patients receiving antiretroviral therapy (ART) in Korea. The outcomes were determined by time periods, during the first year of ART and during 1-5 yr after ART initiation, respectively. Patients lost to follow-up were traced to ascertain survival status. Among 327 patients initiating ART during 1998-2006, 68 patients (20.8%) died during 5-yr follow-up periods. Mortality rate per 100 person-years was 8.69 (95% confidence interval, 5.68-12.73) during the first year of ART, which was higher than 4.13 (95% confidence interval, 2.98-5.59) during 1-5 yr after ART. Tuberculosis was the most common cause of death in both periods (30.8% within the first year of ART and 16.7% during 1-5 yr after ART). During the first year of ART, clinical category B and C at ART initiation, and underlying malignancy were significant risk factors for mortality. Between 1 and 5 yr after ART initiation, CD4 cell count < or = 50 cells/microL at ART initiation, hepatitis B virus co-infection, and visit constancy < or = 50% were significant risk factors for death. This suggests that different strategies to reduce mortality according to the time period after ART initiation are needed.
