Abstract
Identify risk factors associated with mortality in HIV patients admitted to an ICU in the city of Bogotá. Retrospective cohort study of patients treated in an ICU during the years 2017–2019. The analysis included descriptive statistics, association tests, and a logistic regression model. A predictive model of mortality at the time of admission to the ICU was developed. 110 HIV patients were identified. Association was found between a Charlson index ≥ 6 and mortality (OR = 2.3, 95% CI 1.0–5.1) and an increase in mortality in the first 21 days of ICU stay (OR = 2.2, 95% CI 1.0–4.9). In the logistic regression analysis, the absence of highly active antiretroviral therapy (HAART) upon admission to the ICU (OR = 2.5 95% CI 1.0–6.1) and the first 21 days of ICU stay (OR = 2.3 95% CI 1.0–5.4) were associated with an increase in mortality. The predictive mortality model established that mortality was higher in patients admitted to the ICU without having previously received HAART than in those who did receive therapy at the time of admission to the ICU. In patients with HIV admitted to the ICU, the absence of HAART will negatively impact mortality during their hospital stay.

Abstract
Introduction Combined antiretroviral therapy has led to significant decreases in morbidity and mortality in acquired immunodeficiency syndrome patients. Survival among these patients admitted to intensive care units has also improved in the last years. However, the prognostic predictors of human immunodeficiency vírus patients in intensive care units have not been adequately studied. The main objective of this study was to evaluate if non-adherence to antiretroviral therapy is a predictor of hospital mortality. Methods A unicentric, retrospective, cohort study composed of patients admitted to a 59-bed mixed intensive care unit including all patients with human immunodeficiency vírus infection. Patients were excluded if exclusive palliative care was established before completing 48 h of intensive care unit admission. Clinical and treatment data were obtained, including demographic records, underlying diseases, Simplified Acute Physiology III score at the time of intensive care unit admission, CD4 lymphocyte count, antiretroviral therapy adherence, admission diagnosis, human immunodeficiency vírus-related diseases, sepsis and use of mechanical ventilation and hemodialysis. The outcome analyzed was hospital mortality. Results Overall, 167 patients were included in the study, and intensive care unit mortality was 34.7%. Multivariate analysis indicated that antiretroviral therapy adherence and the Simplified Acute Physiology 3 score were independently related to hospital mortality. antiretroviral therapy adherence was a protective factor (OR 0.2; 95% CI 0.05-0.71; P = 0.01), and Simplified Acute Physiology 3 (OR 1.04; 95% CI 1.01-1.08; P < 0.01) was associated with increased hospital mortality. Conclusion Non-adherence to antiretroviral therapy is associated with hospital mortality in this population. Highly active antiretroviral therapy non-adherence may be associated with other comorbidities that may be associated with a worst prognosis in this scenario.

Abstract
PURPOSE To identify factors associated with do-not-resuscitate (DNR) status in critically ill patients infected with human immunodeficiency virus (HIV) admitted to the Intensive Care Unit (ICU) in the era of combination antiretroviral therapy (cART). MATERIALS AND METHODS Retrospective cohort study of first-time admissions of HIV-infected patients to ICUs in Edmonton, Alberta, from 2002 to 2014. Multivariable logistic regression analysis was performed to identify factors associated with DNR status. RESULTS There were 282 HIV-infected patients with first-time ICU admissions, with an incidence rate of 6.6 per 1000 ICU admissions. Sixty-seven (24%) patients had a DNR designation and support was withdrawn in 37 (13%). In multivariable analysis, APACHE II score (OR 1.13; 95% CI, 1.08-1.19, p < 0.001), coronary artery disease (OR 5.70; 95% CI, 1.18-27.76, p = 0.031), prior opportunistic infection (OR 2.59; 95% CI, 1.20-5.57, p = 0.015) and duration of HIV infection (OR 1.07 per year; 95% CI, 1.01-1.14, p = 0.025) were independently associated with DNR status. Ethnicity, HIV risk factors, CD4 count and viral load were not associated with DNR status. CONCLUSIONS One in four patients had a DNR designation. Illness acuity, selected comorbidity, previous opportunistic infection and HIV duration were associated with DNR designation.

Abstract
Few modern diseases have experienced as rapid and dramatic change in prognosis and treatment as HIV infection. The introduction of active antiretroviral therapy (ART) and effective prophylaxis of opportunistic infections ushered in a new era in the treatment of HIV infection and changed dramatically the natural history of this disease. The rates of admission to the intensive care unit (ICU) and intensive care mortality in patients with HIV infection have shifted repeatedly during the AIDS epidemic, influenced by attitudes of patients and providers toward utility of care. In the ART era, patients with HIV infection admitted to the ICU fall into 3 general categories: those with AIDS-related opportunistic infections, those who are experiencing complications related to ART, and those with medical problems unrelated to HIV infection. In this article, the authors provide a review of the most common life-threatening complications in patients with HIV infection.

Abstract
BACKGROUND Tuberculosis is one of the leading causes of death from infectious diseases worldwide, mainly after the human immunodeficiency virus (HIV) epidemics. Patient with HIV-related illness are more likely to present with severe TB due to immunosuppression. Very few studies have explored HIV/TB co-infection in critically ill patients. The goal of this study was to analyze factors associated with long-term mortality in critically ill patient with HIV-related disease coinfected with TB. METHODS We conducted a retrospective study in an infectious disease reference center in Brazil that included all patient with HIV-related illness admitted to the ICU with laboratory-confirmed tuberculosis from March 2007 until June 2012. Clinical and laboratory variables were analyzed based on six-month survival. RESULTS Forty-four patients with HIV-related illness with a confirmed diagnosis of tuberculosis were analyzed. The six-month mortality was 52 % (23 patients). The main causes of admission were respiratory failure (41 %), severe sepsis/septic shock (32 %) and coma/torpor (14 %). The median time between HIV diagnosis and ICU admission was 5 (1-60) months, and 41 % of patients received their HIV infection diagnosis ≤ 30 days before admission. The median CD4 count was 72 (IQR: 23-136) cells/mm(3). The clinical presentation was pulmonary tuberculosis in 22 patients (50 %) and disseminated TB in 20 patients (45.5 %). No aspect of TB diagnosis or treatment was different between survivors and nonsurvivors. Neurological dysfunction was more prevalent among nonsurvivors (43 % vs. 14 %, p = 0.04). The nadir CD4 cell count lower than 50 cells/mm(3) was independently associated with Six-month mortality (hazard ratio 4.58 [1.64-12.74], p < 0.01), while HIV diagnosis less than three months after positive serology was protective (hazard ratio 0.27, CI 95 % [0.10-0.72], p = 0.01). CONCLUSION The Six-month mortality of HIV critically ill patients with TB coinfection is high and strongly associated with the nadir CD4 cell count less than 50 cels/mm(3).

Abstract
OBJECTIVE Knowledge on characteristics and outcome of ICU patients with AIDS is highly limited. We aimed to determine the main reasons for admission and outcome in ICU patients with AIDS and trends over time therein. DESIGN A retrospective study within the Dutch National Intensive Care Evaluation registry. SETTING Dutch ICUs. PATIENTS We used data collected between 1997 and 2014. Characteristics of patients with AIDS were compared with ICU patients without AIDS, matched for age, sex, admission type, and admission year. Joinpoint regression analysis was applied to study trends over time. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We included 1,127 patients with AIDS and 4,479 matched controls. The main admission diagnoses of patients with AIDS were respiratory infection (28.6%) and sepsis (16.9%), which were less common in controls (7.7% and 7.5%, respectively; both p < 0.0001). Patients with AIDS had increased severity of illness and in-hospital mortality (28.2% vs 17.8%; p < 0.0001) compared with controls, which was associated with a higher rate of infections at admission in patients with AIDS (58.4% vs 25.5%). Over time, the proportion of patients with AIDS admitted with an infection decreased (75% in 1999 to 56% in 2013). Mortality declined in patients with AIDS (39% in 1999 to 16% in 2013), both in patients with or without an infection. Mortality also declined in matched controls without AIDS, but to a lesser extent. CONCLUSION Infections are still the main reason for ICU admission in patients with AIDS, but their prevalence is declining. Outcome of patients with AIDS continued to improve during a time of widespread availability of combination antiretroviral therapy, and mortality is reaching levels similar to ICU patients without AIDS.

Abstract
According to estimates, 1.2 million Americans are infected with human immuno deficiency virus (HIV). Because of antiretroviral therapy, persons who have HIV infection or have progressed to AIDS are living longer. As a result, the likelihood that they will need critical care nursing is increasing. Unlike in years past, when these patients were often admitted because of the consequences of immunosuppression, today they are also being cared for in critical care units for other conditions associated with aging, other chronic health conditions, and trauma. When persons who have HIV disease or AIDS are admitted to the intensive care unit, nurses must be prepared to provide care, especially management of complexities associated with antiretroviral therapy. Therefore, this article examines critical care nurses' role in initiating and administering antiretroviral therapy in the intensive care unit and reducing the risk of drug interactions associated with the therapy.

Abstract
Respiratory failure in HIV-infected patients is a relatively common presentation to ICU. The debate on ICU treatment of HIV-infected patients goes on despite an overall decline in mortality amongst these patients since the AIDS epidemic. Many intensive care physicians feel that ICU treatment of critically ill HIV patients is likely to be futile. This is mainly due to the unfavourable outcome of HIV patients with Pneumocystis jirovecii pneumonia who need mechanical ventilation. However, the changing spectrum of respiratory illness in HIV-infected patients and improved outcome from critical illness remain under-recognised. Also, the awareness of certain factors that can affect their outcome remains low. As there are important ethical and practical implications for intensive care clinicians while making decisions to provide ICU support to HIV-infected patients, a review of literature was undertaken. It is notable that the respiratory illnesses that are not directly related to underlying HIV disease are now commonly encountered in the highly active antiretroviral therapy (HAART) era. The overall incidence of P. jirovecii as a cause of respiratory failure has declined since the AIDS epidemic and sepsis including bacterial pneumonia has emerged as a frequent cause of hospital and ICU admission amongst HIV patients. The improved overall outcome of HIV patients needing ICU admission is related to advancement in general ICU care, including adoption of improved ventilation strategies. An awareness of respiratory illnesses in HIV-infected patients along with an appropriate diagnostic and treatment strategy may obviate the need for invasive ventilation and improve outcome further. HIV-infected patients presenting with respiratory failure will benefit from early admission to critical care for treatment and support. There is evidence to suggest that continuing or starting HAART in critically ill HIV patients is beneficial and hence should be considered after multidisciplinary discussion. As a very high percentage (up to 40%) of HIV patients are not known to be HIV infected at the time of ICU admission, the clinicians should keep a low threshold for requesting HIV testing for patients with recurrent pneumonia.

Abstract
INTRODUCTION Intensive care mortality of HIV-positive patients has progressively decreased. However, critically ill HIV-positive patients with sepsis present a worse prognosis. To better understand this condition, we propose a study comparing clinical, etiological and inflammatory data, and the hospital course of HIV-positive and HIV-negative patients with severe sepsis or septic shock. METHODS A prospective observational study enrolling patients with severe sepsis or septic shock associated or not with HIV infection, and admitted to intensive care unit (ICU). Clinical, microbiological and inflammatory parameters were assessed, including C-reactive protein (CRP), procalcitonin (PCT), interleukin-6, interleukin-10 and TNF-α. Outcome measures were in-hospital and six-month mortality. RESULTS The study included 58 patients with severe sepsis/septic shock admitted to ICU, 36 HIV-positive and 22 HIV-negative. All HIV-positive patients met the criteria for AIDS (CDC/2008). The main foci of infection in HIV-positive patients were pulmonary and abdominal (p=0.001). Fungi and mycobacteria were identified in 44.4% and 16.7% of HIV-positive patients, respectively. In contrast, the main etiologies for sepsis in HIV-negative patients were Gram-negative bacilli (36.4%) and Gram-positive cocci (36.4%) (p=0.001). CRP and PCT admission concentrations were lower in HIV-positive patients (130 vs. 168 mg/dL p=0.005, and 1.19 vs. 4.06 ng/mL p=0.04, respectively), with a progressive decrease in surviving patients. Initial IL-10 concentrations were higher in HIV-positive patients (4.4 pg/mL vs. 1.0 pg/mL, p=0.005), with moderate accuracy for predicting death (area under receiver-operating characteristic curve =0.74). In-hospital and six-month mortality were higher in HIV-positive patients (55.6 vs. 27.3% p=0.03, and 58.3 vs. 27.3% p=0.02, respectively). CONCLUSIONS The course of sepsis was more severe in HIV-positive patients, with distinct clinical, etiological and inflammatory characteristics.

Abstract
Background The purpose of this study was to assess the short- and long-term outcomes of HIV-infected patients admitted to intensive care units (ICU) according to immunovirological status at admission and highly active antiretroviral therapy (HAART) use in ICU. Methods Retrospective study of 98 HIV-infected patients hospitalized between 1997 and 2008 in two medical ICU in Montpellier, France. The primary outcome was mortality in ICU. The secondary end point was probability of survival in the year following ICU admission. Results Eighty-two (83.6%) admissions in ICU were related to HIV infection and 45% of patients had received HAART before admission. Sixty-two patients (63.3%) were discharged from ICU, and 34 (34.7%) were alive at 1 year. Plasma HIV RNA viral load (VL) and CD4+ cell count separately were not associated with outcome. Independent predictors of ICU mortality were the use of vasopressive agents (odds ratio (OR), 3.779; 95% confidence interval (CI), 1.11–12.861; p = 0.0334) and SAPS II score (OR, 1.04; 95% CI, 1.003-1.077; p = 0.0319), whereas introducing or continuing HAART in ICU was protective (OR, 0.278; 95% CI, 0.082-0.939; p = 0.0393). Factors independently associated with 1-year mortality were immunovirological status with high VL (>3 log10/ml) and low CD4 (<200/mm3; hazard ratio (HR), 5.19; 95% CI, 1.328-20.279; p = 0.0179) or low VL (<3 log10/ml) and low CD4 (HR, 4.714; 95% CI, 1.178-18.867; p = 0.0284) vs. high CD4 and low VL, coinfection with C hepatitis virus (HR, 3.268; 95% CI, 1.29-8.278; p = 0.0125), the use of vasopressive agents (HR, 3.68; 95% CI, 1.394-9.716; p = 0.0085), and SAPS II score (HR, 1.09; 95% CI, 1.057-1.124; p <0.0001). Introducing HAART in a patient with no HAART at admission was associated with a better long-term outcome (HR, 0.166; 95% CI, 0.043-0.642; p = 0.0093). Conclusions In a population of HIV-infected patients admitted to ICU, short- and long-term outcomes are related to acute illness severity and immunovirological status at admission. Complementary studies are necessary to identify HIV-infected patients who benefit from HAART use in ICU according to immunovirological status and the reasons of ICU admission.

Abstract
OBJECTIVE To review the current knowledge of common comorbidities in the intensive care unit, including diabetes mellitus, chronic obstructive pulmonary disease, cancer, end-stage renal disease, end-stage liver disease, HIV infection, and obesity, with specific attention to epidemiology, contribution to diseases and outcomes, and the impact on treatments in these patients. DATA SOURCE Review of the relevant medical literature for specific common comorbidities in the critically ill. RESULTS Critically ill patients are admitted to the intensive care unit for various reasons, and often the admission diagnosis is accompanied by a chronic comorbidity. Chronic comorbid conditions commonly seen in critically ill patients may influence the decision to provide intensive care unit care, decisions regarding types and intensity of intensive care unit treatment options, and outcomes. The presence of comorbid conditions may predispose patients to specific complications or forms of organ dysfunction. The impact of specific comorbidities varies among critically ill medical, surgical, and other populations, and outcomes associated with certain comorbidities have changed over time. Specifically, outcomes for patients with cancer and HIV have improved, likely related to advances in therapy. Overall, the negative impact of chronic comorbidity on survival in critical illness may be primarily influenced by the degree of organ dysfunction or the cumulative severity of multiple comorbidities. CONCLUSION Chronic comorbid conditions are common in critically ill patients. Both the acute illness and the chronic conditions influence prognosis and optimal care delivery for these patients, particularly for adverse outcomes and complications influenced by comorbidities. Further work is needed to fully determine the individual and combined impact of chronic comorbidities on intensive care unit outcomes.

Abstract
France is one of main countries affected by the HIV-outbreak in Europe with more than 120,000 cases, among which 34,600 patients having developed an AIDS. The antiretroviral combination therapies (combined antiretroviral therapy [cART]) reduced by half the mortality. A low compliance to cART alters the virologic control and increases the morbimortality. If required, the therapeutic break should be the shortest possible, including the whole treatment (to limit the risk of viral resistance). The perioperative care should take into account the underlying conditions. During the preoperative period, the clinical picture could combine various complications: 1: respiratory impairment; 2: impairment of neuronal functions (related to viral factors, host response and environmental factors such as alcohol, drug addiction, HCV co-infection) inducing a cognitive dysfunction or a peripheral neuropathy; 3: lipodystrophy, dyslipidemia and insulin resistance are the main metabolic cART-related side effects, responsible for atherosclerosis and coronaropathy; 4: major nutritional impairment. Anesthesia for HIV patients is almost the same than usual, without HIV-related contraindication to regional anesthesia. Anesthetic drugs can be associated to cART. The main restriction belongs to the protease inhibitors, which could affect the metabolic pathways of opioids, NSAIDs and benzodiazepines (over dosage risks). During the postoperative period, the follow-up should include the thromboembolism prevention (increased risk compared to main people), the cardiovascular side effects, the nutritional status and the continuation of the treatment. Moreover, the psychological status related and a close collaboration with the corresponding physician is critical.

Abstract
As HIV-infected persons on combination antiretroviral therapy (ART) are living longer and rates of opportunistic infections have declined, serious non-AIDS-related diseases account for an increasing proportion of deaths. Consistent with these changes, non-AIDS-related illnesses account for the majority of ICU admissions in more recent studies, in contrast to earlier eras of the AIDS epidemic. Although mortality after ICU admission has improved significantly since the earliest HIV era, it remains substantial. In this article, we discuss the current state of knowledge regarding the impact of ART on incidence, etiology, and outcomes of critical illness among HIV-infected patients. In addition, we consider issues related to administration of ART in the ICU and identify important areas of future research.

Abstract
INTRODUCTION Although access to highly active antiretroviral therapy (HAART) has prolonged survival and improved life quality, HIV-infected patients with severe immunosuppression or comorbidities may develop complications that require critical care support in intensive care units (ICU). This study aimed to describe the etiology and analyze the prognostic factors of HIV-infected Taiwanese patients in the HAART era. METHODS Medical records of all HIV-infected adults who were admitted to ICU at a university hospital in Taiwan from 2001 to 2010 were reviewed to record information on patient demographics, receipt of HAART, and reason for ICU admission. Factors associated with hospital mortality were analyzed. RESULTS During the 10-year study period, there were 145 ICU admissions for 135 patients, with respiratory failure being the most common cause (44.4%), followed by sepsis (33.3%) and neurological disease (11.9%). Receipt of HAART was not associated with survival. However, CD4 count was independently predictive of hospital mortality (adjusted odds ratio [AOR], per-10 cells/mm3 decrease, 1.036; 95% confidence interval [CI], 1.003 to 1.069). Admission diagnosis of sepsis was independently associated with hospital mortality (AOR, 2.91; 95% CI, 1.11 to 7.62). A hospital-to-ICU interval of more than 24 hours and serum albumin level (per 1-g/dl decrease) were associated with increased hospital mortality, but did not reach statistical significance in multivariable analysis. CONCLUSIONS Respiratory failure was the leading cause of ICU admissions among HIV-infected patients in Taiwan. Outcome during the ICU stay was associated with CD4 count and the diagnosis of sepsis, but was not associated with HAART in this study.

Abstract
With the introduction of highly active antiretroviral therapy (HAART), HIV has become a chronic disease. As HIV-infected patients are aging, they are at increased risk for comorbid diseases. These non-AIDS related diseases account for a growing proportion of intensive care unit (ICU) admissions in HIV-infected patients in recent studies. HIV-infected patients still present to the ICU with HIV-related conditions such as Pneumocystis jirovecii pneumonia (PCP), but these conditions are becoming less common. Respiratory failure remains the most common indication for ICU admission. Immune reconstitution inflammatory response syndrome and toxicities related to HAART may also result in ICU admission. While ICU survival has improved since the earliest era of the HIV epidemic, hospital mortality for HIV-infected patients admitted to the ICU remains around 30%. Risk factors for ICU mortality include poor functional status, weight loss, more than one year between HIV diagnosis and ICU admission, lower serum albumin, higher severity of illness, need for mechanical ventilation, and respiratory failure-particularly if due to PCP and accompanied by pneumothorax. The impact of HAART on ICU outcomes is unclear. HAART administration in the ICU can be challenging due to limited delivery routes, concern for viral resistance and medication toxicities. There are no data to determine the safety or efficacy of HAART initiation in the ICU. Future studies are needed to address the role of age, associated comorbidities and impact of HAART on outcomes of HIV-infected patients admitted to the ICU.

Abstract
OBJECTIVE We aimed to investigate the prognosis of HIV-infected patients with acute neurological complications at the highly active antiretroviral therapy (HAART) era. METHODS We performed a retrospective study in HIV-infected patients admitted to a medical ICU with neurological complications between 2001 and 2008. RESULTS Among the 210 studied patients (median [interquartile range] CD4-cell count: 80 [18-254]/μL; HIV viral load: 4.8 [2-5.3] log₁₀/mL), 40 (19%) had unknown HIV status at admission. Neurological complications consisted in delirium (45%), coma (39%), seizures (32%) and/or intracranial hypertension (21%). Admission diagnoses were AIDS-defining CNS disease for 88 (42%) patients, non-AIDS-defining CNS disease for 45 (21%), and systemic disease with neurological signs for 77 (37%). Seizures (p=0.003), focal deficit (p<0.001) and intracranial hypertension (p<0.001) were more frequently observed in patients with AIDS-defining CNS disease. Factors independently associated with ICU mortality (29.5%) were intracranial hypertension [odds ratio (OR), 5.09; 95% confidence interval (95% CI), 2.17-11.91], vasopressor use [OR, 3.92; 95% CI, 1.78-8.60] and SAPS II score [per 10-point increment, OR, 1.59; 95% CI, 1.31-1.93]. CONCLUSIONS Prognosis of HIV-infected patients with neurological complications depends rather on clinical presentation than on HIV-related parameters. Intracranial hypertension symptoms at admission have a major impact on outcome.

Abstract
BACKGROUND AND OBJECTIVE To survey the Italian intensivist policy towards critically ill patients with HIV or AIDS in the era of highly active antiretroviral therapy (HAART). METHODS This was a multicentre questionnaire survey involving all of the 239 ICUs of the GiViTI (Italian Group for Evaluation of Interventions in ICU) network. In January 2006, a detailed questionnaire (see Appendix) was e-mailed to the GiViTI referring ICU physician in each of the 239 ICUs on the GiViTI list. There were no interventions. RESULTS A total of 126 ICU physicians (52.7%) responded. The number of referred yearly admissions was low: 85.7% of ICUs usually admit five or fewer patients infected with HIV or AIDS per year; only 10.2 and 4.2% of them admitted at least 15 HIV-infected and at least 15 AIDS patients, respectively; the admission of patients with HIV or AIDS is perceived as always appropriate in only 30.4 and 14.3% of ICUs, respectively. A bivariate correlation was found between the presence of an infectious disease ward and the number of referred yearly admissions of both HIV-infected (Spearman rho=0.295, P<0.05) and AIDS patients (Spearman rho=0.304, P<0.05) and the decision to admit or not patients with HIV or AIDS patients to ICU. If an infectious disease ward was available, the intensivist was more likely to take the decision to admit a patient with HIV (Spearman rho=0.637, P<0.05) or AIDS in consultation with an infectious disease specialist (Spearman rho=0.578, P=0.01). CONCLUSION The recorded wide variation in intensivists' approach towards patients with HIV or AIDS requires the production of high-quality evidence to identify an optimal shared policy for such patients.

Abstract
OBJECTIVE To evaluate the impact of human immunodeficiency virus infection on hospital mortality in patients with acute lung injury and to evaluate predictors of mortality among acute lung injury patients with human immunodeficiency virus. DESIGN, SETTING, AND PATIENTS Retrospective study of human immunodeficiency virus-infected patients enrolled in an ongoing prospective cohort study of acute lung injury patients conducted at 13 intensive care units in four teaching hospitals in Baltimore, Maryland. MEASUREMENTS AND MAIN RESULTS Of 520 consecutive acute lung injury patients, 66 (13%) were human immunodeficiency virus-positive. In human immunodeficiency virus-positive vs. human immunodeficiency virus-negative patients, pneumonia was the most common acute lung injury risk factor (43 [65%] vs. 184 [41%]; p=.001), and the median (interquartile range) Acute Physiology and Chronic Health Evaluation II score was modestly higher (27 [22-33] vs. 26 [20-33]; p=.06). There was no difference in crude hospital mortality (44% vs. 46%; p=.78) between human immunodeficiency virus-positive and human immunodeficiency virus-negative acute lung injury patients. After adjustment for potential confounders, human immunodeficiency virus infection was not an independent predictor of hospital mortality (odds ratio, 1.39; 95% confidence interval, 0.69-2.78; p=.35). In the human immunodeficiency virus-infected acute lung injury patients, among 23 relevant measures of intensive care unit and human immunodeficiency virus severity of illness, only the presence of an opportunistic infection before hospital admission was independently associated with hospital mortality (odds ratio, 6.4; 95% confidence interval, 1.27-32.3; p=.025). CONCLUSIONS In patients with acute lung injury, human immunodeficiency virus-positive patients had similar hospital mortality as human immunodeficiency virus-negative patients; hence, human immunodeficiency virus status should not influence estimates of short-term prognosis for acute lung injury patients in the intensive care unit. Among human immunodeficiency virus-positive patients with acute lung injury, the presence of a previous opportunistic infection, rather than traditional measures of severity of illness, may be most strongly predictive of hospital mortality.

Abstract
Introduction The widespread use of highly active antiretroviral therapy (ART) has reduced HIV-related life-threatening infectious complications. Our objective was to assess whether highly active ART was associated with improved survival in critically ill HIV-infected patients. Methods A retrospective study from 1996 to 2005 was performed in a medical intensive care unit (ICU) in a university hospital specialized in the management of immunocompromised patients. A total of 284 critically ill HIV-infected patients were included. Differences were sought across four time periods. Risk factors for death were identified by multivariable logistic regression. Results Among the 233 (82%) patients with known HIV infection before ICU admission, 64% were on highly active ART. Annual admissions increased over time, with no differences in reasons for admission: proportions of patients with newly diagnosed HIV, previous opportunistic infection, CD4 counts, viral load, or acute disease severity. ICU and 90-day mortality rates decreased steadily: 25% and 37.5% in 1996 to 1997, 17.1% and 17.1% in 1998 to 2000, 13.2% and 13.2% in 2001 to 2003, and 8.6% in 2004 to 2005. Five factors were independently associated with increased ICU mortality: delayed ICU admission (odds ratio (OR), 3.04; 95% confidence interval (CI), 1.29 to 7.17), acute renal failure (OR, 4.21; 95% CI, 1.63 to 10.92), hepatic cirrhosis (OR, 3.78; 95% CI, 1.21 to 11.84), ICU admission for coma (OR, 2.73; 95% CI, 1.16 to 6.46), and severe sepsis (OR, 3.67; 95% CI, 1.53 to 8.80). Admission to the ICU in the most recent period was independently associated with increased survival: admission from 2001 to 2003 (OR, 0.28; 95% CI, 0.08 to 0.99), and between 2004 and 2005 (OR, 0.13; 95% CI, 0.03 to 0.53). Conclusions ICU survival increased significantly in the highly active ART era, although disease severity remained unchanged. Co-morbidities and organ dysfunctions, but not HIV-related variables, were associated with death. Earlier ICU admission from the hospital ward might improve survival.

Abstract
PURPOSE OF REVIEW Respiratory infections remain a major cause of morbidity among HIV-infected persons. Thus, knowledge of recent advances regarding HIV-associated opportunistic pneumonias is crucial for optimal care of HIV-infected persons. RECENT FINDINGS Bacterial pneumonia is the most common HIV-associated opportunistic pneumonia in the USA and its incidence remains appreciable. Worldwide, tuberculosis dominates the clinical picture. The absence of rapid, affordable diagnostics for active and latent tuberculosis remains a major obstacle that must be overcome if the global epidemic is to be slowed. The specter of extensively drug resistant tuberculosis and its overlap with HIV infection highlight the importance of rapid diagnostics and the need for accessible drug susceptibility testing. Pneumocystis (carinii) jirovecii pneumonia appears to be a more common pneumonia among HIV-infected persons residing in developing countries than was previously appreciated. Similar to tuberculosis, the absence of available diagnostics in developing areas is a major obstacle to clinical care and epidemiologic studies. The critical care of HIV-infected persons is challenging. SUMMARY Although tremendous advances have been made in our understanding of the management, treatment, and prevention of HIV and its associated respiratory infections, significant gaps remain. Thus, continued epidemiologic, clinical, and bench research is needed.

Abstract
BACKGROUND Little is known about the effect of provider type and experience on outcomes, resource use, and processes of care of hospitalized patients with human immunodeficiency virus (HIV) infection. Hospitalists are caring for this population with increasing frequency. METHODS Data from a natural experiment in which patients were assigned to physicians on the basis of call cycle was used to study the effects of provider type-that is, hospitalist versus nonhospitalist-and HIV-specific inpatient experience on resource use, outcomes, and selected measures of processes of care at 6 academic institutions. Administrative data, inpatient interviews, 30-day follow-up interviews, and the National Death Index were used to measure outcomes. RESULTS A total of 1207 patients were included in the analysis. There were few differences in resource use, outcomes, and processes of care by provider type and experience with HIV-infected inpatients. Patients who received hospitalist care demonstrated a trend toward increased length of hospital stay compared with patients who did not receive hospitalist care (6.0 days vs. 5.2 days; P = .13). Inpatient providers with moderate experience with HIV-infected patients were more likely to coordinate care with outpatient providers (odds ratio, 2.40; P = .05) than were those with the least experience with HIV-infected patients, but this pattern did not extend to providers with the highest level of experience. CONCLUSION Provider type and attending physician experience with HIV-infected inpatients had minimal effect on the quality of care of HIV-infected inpatients. Approaches other than provider experience, such as the use of multidisciplinary inpatient teams, may be better targets for future studies of the outcomes, processes of care, and resource use of HIV-infected inpatients.

Abstract
BACKGROUND Little is known about the most severe forms of Pneumocystis jiroveci pneumonia (PCP) in HIV-negative as compared with HIV-positive patients. Improved knowledge about the differential characteristics and management modalities could guide treatment based on HIV status. METHODS We retrospectively compared 72 patients (73 cases, 46 HIV-positive) admitted for PCP from 1993 to 2006 in the intensive care unit (ICU) of a university hospital. RESULTS The yearly incidence of ICU admissions for PCP in HIV-negative patients increased from 1993 (0%) to 2006 (6.5%). At admission, all but one non-HIV patient were receiving corticosteroids. Twenty-three (85%) HIV-negative patients were receiving an additional immunosuppressive treatment. At admission, HIV-negative patients were significantly older than HIV-positive patients (64 [18 to 82] versus 37 [28 to 56] years old) and had a significantly higher Simplified Acute Physiology Score (SAPS) II (38 [13 to 90] versus 27 [11 to 112]) but had a similar PaO2/FiO2 (arterial partial pressure of oxygen/fraction of inspired oxygen) ratio (160 [61 to 322] versus 183 [38 to 380] mm Hg). Ventilatory support was required in a similar proportion of HIV-negative and HIV-positive cases (78% versus 61%), with a similar proportion of first-line non-invasive ventilation (NIV) (67% versus 54%). NIV failed in 71% of HIV-negative and in 13% of HIV-positive patients (p < 0.01). Mortality was significantly higher in HIV-negative than HIV-positive cases (48% versus 17%). The HIV-negative status (odds ratio 3.73, 95% confidence interval 1.10 to 12.60) and SAPS II (odds ratio 1.07, 95% confidence interval 1.02 to 1.12) were independently associated with mortality at multivariate analysis. CONCLUSION The yearly incidence of ICU admissions for PCP in HIV-negative patients in our unit increased from 1993 to 2006. The course of the disease and the outcome were worse in HIV-negative patients. NIV often failed in HIV-negative cases, suggesting that NIV must be watched closely in this population.

Abstract
INTRODUCTION HIV infection is increasingly characterized as a chronic condition that can be managed through adherence to a healthy lifestyle, complex drug regimens, and regular treatment and monitoring. The location, quality, and/or affordability of a person's housing can be a significant determinant of his or her ability to meet these requirements. The objective of this systematic review is to inform program and policy development and future research by examining the available empirical evidence on the effects of housing status on health-related outcomes in people living with HIV/AIDS. METHODS Electronic databases were searched from dates of inception through November 2005. A total of 29 studies met inclusion criteria for this review. Seventeen studies received a "good" or "fair" quality rating based on defined criteria. RESULTS A significant positive association between increased housing stability and better health-related outcomes was noted in all studies examining housing status with outcomes of medication adherence (n = 9), utilization of health and social services (n = 5), and studies examining health status (n = 2) and HIV risk behaviours (n = 1). CONCLUSIONS Healthcare, support workers and public health policy should recognize the important impact of affordable and sustainable housing on the health of persons living with HIV.

Abstract
The efficacy of boosted protease inhibitor monotherapy (BPIm) in HIV-positive patients with complex medical problems was assessed in ten patients. With BPIm, median (range) HIV viral load reduction was log10 2.15 (1.62-3.1) by 4-8 weeks; in four patients, viral load was < 400 copies/ml. During follow-up, at median (range) = 50 (8-156) weeks, no patient had an opportunistic illness; one patient developed new PI mutations after 48 weeks. These very preliminary data need further confirmation on a larger scale.

Abstract
PURPOSE Critical care outcomes among HIV-infected patients have improved because of advances in HIV therapy and general improvements in intensive care unit (ICU) management. There is a high co-occurrence of drug and alcohol dependence among HIV-infected patients, and the independent role of drug and alcohol dependence among patients with and without HIV infection in outcomes of critical illness is unclear. MATERIALS AND METHODS We analyzed a prospectively collected database of 7015 index ICU admissions at 2 teaching hospitals between January 1999 and January 2006. The ICU diagnoses were determined from prospective chart review and classified according to the dictionary of diagnoses developed by the Intensive Care National Audit and Research Council. We used logistic regression to determine the independent association of drug and alcohol dependence as well as HIV infection with in-hospital mortality. Covariates that were adjusted for included acute drug overdose, Acute Physiology and Chronic Health Evaluation II score, age, sex, hospital site, and socioeconomic variables. RESULTS Of all patients, 4.4% (309 of 7015) were HIV infected; and of these, 56% (173 of 309) had a history of drug and alcohol dependence, whereas only 7.4% (502 of 6706) of the HIV-negative group had a history of drug and alcohol dependence. Drug and alcohol dependence was not independently associated with hospital mortality in either the model including all admissions (adjusted odds ratio [AOR] 0.80; 95% confidence interval [CI] 0.62-1.03) or the model including pneumonia and sepsis admissions only (AOR 0.92; 95% CI 0.59-1.41). Infection with HIV was independently associated with hospital mortality (AOR 2.16; 95% CI 1.60-2.93). CONCLUSIONS Although HIV infection is associated with increased hospital mortality, drug and alcohol dependence is not associated with an increased hospital mortality independent of HIV infection.

Abstract
Combinatorial therapies for the treatment of HIV infection have changed the course of the AIDS epidemic in developed nations where the antiviral drug combinations are readily available. Despite this progress, there are many problems associated with chemotherapy for AIDS including toxicities and emergence of viral mutants resistant to the drugs. Our goal has been the development of a hematopoietic gene therapy treatment for HIV infection. Like chemotherapy, gene therapy for treatment of HIV infection should be used combinatorially. We have thus combined three different inhibitory genes for treatment of HIV infection into a single lentiviral vector backbone. The inhibitory agents engage RNAi via a short hairpin RNA targeting HIV tat/rev mRNAs, a nucleolar localizing decoy that binds and sequesters the HIV Tat protein, and a ribozyme that cleaves and downregulates the CCR5 chemokine receptor used by HIV for cellular entry. This triple combination has proven to be highly effective for inhibiting HIV replication in primary hematopoietic cells, and is currently on track for human clinical application.

Abstract
Since the initial description of a concentrated outbreak of pneumocystis carnii pneumonia in 1981, the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) pandemic has accounted for nearly 25 million deaths worldwide. This review focuses on estimations of prevalence by geographic region and identification of high-risk populations within each region, outcome for trauma patients with HIV and AIDS and risk management for health care workers who sustain occupational exposures. Trauma surgeons are more likely to encounter patients infected with HIV in geographic areas where HIV prevalence is high or in areas where intravenous drug use, high-risk sexual behaviours and penetrating trauma are more common. Patients with HIV may be expected to have higher rates of infectious and respiratory complications if they have active AIDS and/or liver disease caused by one of the hepatitis viruses. Certain aspects of therapy may change in this group of patients. Clinicians should be aware that highly active anti-retroviral therapy (HAART) might produce complications. Occupational exposure among healthcare workers is uncommon. Cases of infection in healthcare workers from needlesticks are rare. Certain precautions regarding body fluid and needlestick exposures have been widely adopted over the past decade. When percutaneous injury results in known exposure to HIV, post-exposure prophylaxis (PEP) should be used and can be expected to be effective in preventing infection in the large majority of cases.
