Pulmonary manifestations of HIV infection in the era of highly active antiretroviral therapy.

STUDY OBJECTIVES: To determine whether the spectrum of HIV-related pulmonary disease seen by a university medical center Pulmonary and Critical Care Medicine Service has changed since the introduction of highly active antiretroviral therapy (HAART). DESIGN: Retrospective chart review. SETTING: A tertiary care university hospital. PATIENTS: All HIV-infected patients referred to the Pulmonary and Critical Care Medicine Service from January 1, 1993, through December 31, 1995 (era 1) and from July 1, 1997, through June 30, 2000 (era 2). INTERVENTIONS: Inpatient and outpatient charts were reviewed for data regarding patient demographics, CD4 cell counts, viral load levels, duration of HIV seropositivity, history of opportunistic infections, and final diagnosis. RESULTS: Pneumocystis carinii pneumonia (PCP) was less common in the HAART era than in the pre-HAART era, whereas bacterial pneumonia and non-Hodgkin's lymphoma (NHL) were more common in the HAART era than in the pre-HAART era. HAART was protective against PCP (odds ratio [OR], 0.37; confidence interval [CI], 0.16 to 0.89) in a manner dependent on the CD4 cell count. Patients receiving HAART were at increased risk for the development of bacterial pneumonia (OR, 2.41; CI, 1.12 to 5.17) and NHL (OR, 15.11; CI, 3.14 to 28.32). A history of PCP indicated a risk factor for bacterial pneumonia (OR, 2.14; CI, 1.13 to 4.04). A history of cytomegalovirus infection indicated a risk factor for NHL (OR, 6.0; CI, 1.27 to 28.32). CONCLUSIONS: There have been significant changes in the spectrum of HIV-related pulmonary complications seen by our Pulmonary and Critical Care Medicine Service in the HAART era.     

Longitudinal assessment (1995-2003) of hospitalizations of HIV-infected patients within a geographical population in Canada

OBJECTIVES: To determine the frequency of and reasons for hospitalization of adult HIV-infected patients compared with the general population. METHODS: Length of stay, primary/secondary diagnoses and discharge status were reviewed for all HIV-infected patients admitted to Calgary-area hospitals between 1995 and 2003. Admissions were classified as HIV- or non-HIV-related using International Classification of Diseases, 9th and 10th revisions (ICD-9/10) codes and confirmed by chart review. Summary comparative data on admissions for the general population were obtained from the regional administrative database. RESULTS: HIV-infected adults were hospitalized more than twice as frequently, experienced longer stays (median length 5 vs 3 days, respectively) and had higher in-hospital mortality rates (9.1 vs 1.3 per 100 admissions, respectively) than the general population (P < 0.01). Hospitalizations of HIV-infected patients declined by 58% from 1995 to 2003. Patients newly diagnosed with HIV infection accounted for 15% of all HIV-related hospitalizations. HIV-related admissions for known HIV-infected patients decreased from 12 per 100 patient-years-followed in 1995 to 3 per 100 patient-years-followed in 2003. Low CD4 counts, AIDS, and no current use of highly active antiretroviral therapy (HAART) were strongly correlated with hospitalizations (P < 0.01). Non-HIV-related hospitalizations for HIV-infected patients increased by 42% and were associated with comorbidities (e.g. substance use and psychological disorders). CONCLUSION: Despite the reduction in HIV-related hospitalizations following the introduction of HAART, all-cause hospitalization rates have increased and have started to erode this benefit.     

Cholestasis in HIV-infected patients

Cholestasis is frequently observed in the HIV-infected population and can be caused by drugs, such as highly active antiretroviral therapy (HAART) and antimicrobial agents, and by opportunistic infections of the liver. Less common causes such as HIV-related malignancies or biliary tract disease are also encountered. Most disorders respond to medical management, but patient outcome was often dictated by the stage of the HIV infection and concomitant illnesses in the pre-HAART era. Prompt recognition and specific treatment may improve the outcome for these patients in the HAART era.     

The Changing Clinical Spectrum of Human Immunodeficiency Virus (HIV)-Related Oral Lesions in 1,000 Consecutive Patients: A 12-Year Study in a Referral Center in Mexico

In developing countries, the variations in the clinical spectrum of human immunodeficiency virus (HIV)-related oral lesions over time, and the possible effects of antiretroviral therapy, have not been described. In this study we evaluate the clinical spectrum of oral lesions in a series of HIV-infected patients when first examined at the acquired immunodeficiency syndrome (AIDS) clinic of a tertiary care institution in Mexico City, Mexico, and the changes observed over 12 years. All HIV-infected adult patients had an oral examination performed by specialists in oral pathology and medicine who used established clinical diagnostic criteria for oral lesions. Four periods were defined according to the evolving pattern of antiretroviral use: the first 2 were before the introduction of highly active antiretroviral therapy (HAART) and the last 2 were during more established use of HAART. For the statistical analysis the chi-square test for contingency tables and the chi-square test for trend were utilized. For dimensional variables, except age, the Kruskal-Wallis or Mann-Whitney rank sum tests were used when applicable and trend was tested with the Spearman correlation coefficient. Age was tested through analysis of variance (ANOVA) and linear regression analysis. Alpha value was set at p = 0.05 for each test. In the 12-year study, 1,000 HIV-infected patients were included (87.9% male). At the baseline examination, oral lesions strongly associated with HIV were present in 47.1% of HIV-infected patients. Oral candidosis (31.6%), hairy leukoplakia (22.6%), erythematous candidosis (21.0%), and pseudomembranous candidosis (15.8%) were the most frequent lesions. Oral Kaposi sarcoma (2.3%), HIV-associated periodontal disease (1.7%), and oral non-Hodgkin lymphoma (0.1%) were less frequent. HIV-related oral lesions decreased systematically-by half during the course of the 4 study periods (p < 0.001). Except for Kaposi sarcoma, all oral lesions strongly associated with HIV showed a trend to decrease significantly during the study period. No apparent variation in the occurrence of salivary gland disease or human papillomavirus-associated oral lesions was found. A significant trend to a lower prevalence was observed in the group of patients who were already taking antiretroviral therapy, non-HAART and HAART (p < 0.001 and p = 0.004, respectively). Only a discrete reduction, barely significant, was noted among untreated patients (p = 0.060). By Period IV (1999-2001), those who received HAART showed the lowest prevalence of oral lesions strongly associated with HIV (p < 0.001). Patients with oral lesions strongly associated with HIV had significantly lower median CD4+ counts and higher viral loads than those without oral lesions strongly associated with HIV (p < 0.001 and p = 0.005, respectively). When CD4+ counts were correlated with prevalence of oral candidosis, a consistently negative association was found; this association prevailed even after the study group was partitioned according to period. In this selected cohort of 1,000 patients with HIV infection, the clinical spectrum of HIV-related oral lesions has changed over the 12-year study, with a decreased prevalence of most oral lesions. Our findings probably represent improvements in medical care of HIV-infected persons, earlier detection of HIV-infected patients at the AIDS clinic, the increasing use of prophylactic drugs to prevent secondary AIDS-related opportunistic infections, and, perhaps most important, the availability of potent antiretroviral therapy in recent years, since the introduction of HAART.     

Trends in HIV-related morbidity among patients admitted to a South Indian tertiary hospital between 1997 and 2003

This paper describes trends in HIV-related morbidity among people living with HIV/AIDS (PLWHA) admitted to a tertiary hospital in Chennai, South India, between 1997 and 2003. Patients comprised HIV-infected men, women and children who had been admitted at least once to YR Gaitonde Centre for AIDS Research and Education (YRGCARE). A non-parametric trends analysis was conducted to observe trends in clinical and demographic parameters and diagnoses at admission over the seven-year period. Among clinical and demographic parameters, we identified a significantly increasing time trend in the use of antiretroviral therapy (p<0.001) and a significant decrease in the mean hemoglobin level (p=0.01). Among diagnoses at admission, we identified a decreasing time trend for admissions due to pulmonary tuberculosis (p<0.001) and increasing trends for admissions due to extra pulmonary tuberculosis (p<0.01), toxoplasmosis (p<0.01), Pneumocystis carinii pneumonia (p=0.02) and anemia (p<0.001). The results indicate a changing pattern among the clinical conditions requiring admission. With increasing proportions of patients initiating highly active antiretroviral therapy (HAART), it is probable that adverse events due to HAART will account for larger proportions of admissions in the years to come, as is being seen in the industrialized countries.     

Impact of HAART advent on admission patterns and survival in HIV-infected patients admitted to an intensive care unit

BACKGROUND: Several studies found increased survival times and decreased hospitalization rates since the introduction of highly active antiretroviral therapy (HAART). OBJECTIVE: To examine the impact of HAART on admission patterns and survival of HIV-infected patients admitted to an intensive care unit (ICU). DESIGN: Prospective observational cohort study. SETTING AND SUBJECTS: All HIV-infected patients admitted from 1 January 1995 to 30 June 1999, to an infectious diseases ICU located in Paris. MAIN OUTCOME MEASURES: ICU utilization and admission patterns, and survival. RESULTS: A total of 426 HIV-related admissions were included. Sepsis increased from 16.3% to 22.6% from the pre- to the post-HAART era, whereas AIDS-related admissions decreased from 57.7% to 37% (P < 0.05). No significant difference in ICU utilization was found. In both periods, half of the patients were not on antiretroviral treatment at ICU admission. In-ICU mortality was 23%, without significant difference between the study periods. By multivariable analysis, in-ICU mortality was significantly associated with SAPS II > 40, Omega score > 75 and mechanical ventilation; and long-term survival with admission in the HAART era and AIDS at ICU admission. Cumulative survival rates after ICU discharge were 85.3% and 70.8% after 12 and 24 months, respectively. CONCLUSIONS: HAART had little impact on ICU utilization by HIV-infected patients. After the introduction of HAART AIDS-related conditions decreased and sepsis increased as reasons for ICU admission. Whereas ICU survival was dependent on usual prognostic markers, long-term survival was clearly dependent on HIV disease stage and HAART availability. In both study periods, at least a half of the HIV infected patients were not on anti-retroviral treatment at the time of ICU admission.     

Current status of inpatient HIV care at a tertiary care center in Nepal

The success of the WHO's '3 by 5' programme will depend on the ability of developing countries to provide antiretroviral therapy. The purpose of this study was to determine the current status of HIV care at a major teaching hospital in eastern Nepal. A retrospective cohort study was conducted of admitted HIV-infected patients at BPKIHS between 1993 and 2003, evaluating reasons for admission and the care received. There were 2, 2, 2, 3, 5 and 18 admissions, respectively, from 1998 to 2003. Only 4 were female patients. Two were children, both admitted in the last y studied. 10 admissions (31% of the total) were for opportunistic infections (OIs). Seven patients were prescribed OI prophylaxis, with incorrect dosages in 6. Four patients were prescribed antiretroviral therapy, all in inappropriate dosages or combinations. 13 patients were rapidly discharged without further care as soon as a diagnosis of HIV was made. Hospital admissions of HIV-infected individuals are increasing rapidly. Important segments of the HIV-infected population such as women and children are not receiving medical services. Most admissions are not due to OIs. The care of HIV-infected patients even at a major tertiary care teaching hospital in Nepal is sub-optimal.

目的 了解中国部分HIV/MDS患者在高效抗逆转录病毒治疗(HAART)后HIV相关脂肪营养不良综合征(HIV-LD)的临床特点和危险因素.方法 收集2007年3-5月期间在我院门诊随诊的成年HIV/AIDS患者55例,根据患者报告和医师评估结果 ,将上述患者分成HIV-LD组与非脂肪营养不良综合征(HIV-NLD)组.对两组HIV/AIDS患者进行全身双能X射线扫描(DEXA),并比较两组间临床特点、治疗过程及实验室检查指标的差异,分析发生HIV-LD的可能危险因素.结果 55例HIV/AIDS患者中,脂肪异常分布发生率为47.3%.多因素分析结果 显示,HAART暴露2年以上、司他夫定(d4T)暴露1年以上与HIV-LD的发生独立相关.DEXA结果 显示,HIV/AIDS患者脂肪异常分布主要表现为外周脂肪萎缩.结论 脂肪异常分布在接受HAART的AIDS患者中有较高发生率,表现为外周脂肪萎缩.HAART长期治疗及使用d4T方案,尤其后者,是HIV-LD的独立危险因素.     

Analysing the workload from HIV inpatients: a 10-month retrospective study

To assess the clinical and laboratory workload arising from human immunodeficiency virus (HIV)-related inpatient admissions in a London teaching hospital, a 10-month retrospective audit was performed of the casenotes of all HIV-infected inpatients admitted under the care of one consultant physician. During this period, 84 inpatients were identified who generated 371 admissions, of whom 71 (84.5%) had acquired immunodeficiency syndrome (AIDS). Over two-thirds of admissions were essentially day cases, attributed to blood transfusions, antimicrobial and tumour, chemotherapy, and minor surgery; with blood transfusions alone accounting for 43% of all admissions. Pulmonary infections (pyogenic and cell-mediated opportunist) accounted for 46 (12%) of admissions, with Pneumocystis carinii pneumonia second only to blood transfusions in caseload prevalence score (see below). Neurological complications of AIDS were associated with the longest admissions. Laboratory-based investigations were heavily utilized by AIDS inpatients, particularly bacteriological services. Choice of radiological investigation correlated with the anatomical site of disease presentation: plain radiology for chest symptoms, ultrasound for abdominal symptoms and computerized tomography (CT scanning) for neurological presentations. Drug-induced anaemia accounted for a substantial number of HIV-related admissions for red cell transfusions, which together with the disproportionate workload from daycase-type admissions, might be better handled in lower dependency day wards.     

A significant proportion of HIV-infected patients admitted to hospital have immunosuppression as a result of failure of highly active antiretroviral therapy

OBJECTIVES: To investigate the immunological and virological features of patients on highly active antiretroviral therapy (HAART) admitted to a tertiary centre. METHODS: A retrospective study was carried out on HIV-infected patients on HAART admitted to the Regional Infectious Disease Unit in Edinburgh between June 2002 and July 2003. RESULTS: A total of 125 patients who had been on HAART for at least 6 months were admitted during the study period. The frequencies of hepatitis C virus (HCV) and hepatitis B virus (HBV) coinfection were 52% (78 of 150 patients) and 48% (72 of 150 patients), respectively (P>0.05 for comparison of frequencies of hepatitis B and C). Of patients who had been on HAART for at least 6 months, 50% (63 of 125 patients) were immuno-suppressed and had significantly higher bed-days 6 (3-12) compared with those with CD4>200 cells/microL (P<0.002). Amongst immuno-suppressed patients, 38% (24 of 63) had undetectable viral load after at least 6 months of therapy. Those patients were mostly (67%) intravenous drug users and had a significantly higher median age (43 years; range 38-47 years) than other patients (P<0.001). CONCLUSIONS: Earlier start of HAART and addition of interleukin (IL)-2 to the treatment regimens of patients at risk of slow CD4 T-cell count recovery may reduce the duration of their subsequent hospital admissions.     

The safety, tolerability and effectiveness of generic antiretroviral drug regimens for HIV-infected patients in south India

We investigated the safety, tolerability and effectiveness of locally produced generic highly active antiretroviral therapy (HAART) regimens with a chart review conducted at YRG CARE, a tertiary HIV referral centre in India. A total of 333 patients had been on Indian-manufactured generic HAART for at least 3 months. In this cohort, generic HAART was safe, well tolerated and effective at increasing CD4 T-lymphocyte counts in patients with advanced HIV, comparable to the experience with proprietary HAART.     

The spectrum of HIV-related disease in rural Central Thailand

To determine the spectrum of HIV-related illnesses presenting to a rural primary and secondary healthcare facility in Central Thailand, a cross-sectional study was conducted. Routinely collected data were extracted from outpatient medical notes for all adult HIV-infected new attenders of the Manorom Christian Hospital Infectious Disease Clinic. Data concerning inpatient admissions of HIV-infected individuals were collected from ward admission books and discharge summaries. Complete data were available for 229 outpatients, 70% of whom were men. The median age at presentation was 31 years for men and 30 years for women. The majority of the outpatients were married (69%) and infected heterosexually (91%). The commonest conditions requiring admission were cryptococcal meningitis (15%), bacterial pneumonia (12%), extrapulmonary tuberculosis (12%), Pneumocystis carinii pneumonia (7%), cerebral toxoplasmosis (4%) and pulmonary tuberculosis (3%). Of the patients presenting for the first time, 32% had AIDS-defining illnesses. Presentations with some conditions, such as tuberculosis and septicemia, were fewer than expected. The common opportunistic infections among HIV-infected adults in this rural region are treatable and preventable. Most patients present with advanced disease and earlier diagnosis, through improved access to voluntary counseling and testing, would enable them to receive appropriate preventive therapies and antiretrovirals as they becomes available. The high prevalence of cryptococcal disease suggests that prophylactic anti-fungal therapy may be of value in this area. Septicemia and tuberculosis may be under-diagnosed, highlighting the need for improved diagnostic laboratory facilities or treatment based upon validated clinical algorithms. Community care and palliative care services for HIV-infected individuals will increasingly be required in this region.     

The spectrum of HIV-1-related disease among outpatients in New York City.

OBJECTIVES: To define the spectrum of HIV-1-related disease in New York City (NYC) and to determine how the clinical spectrum of illness differs in various populations. DESIGN AND METHODS: The medical records of the 2983 HIV-infected individuals who had received care through 1989 at four hospital outpatient clinics and two private physicians' offices were reviewed retrospectively. RESULTS: Sixty-one per cent of the study patients and 48% of patients seen in 1989 had AIDS. HIV-infected women were significantly less likely to have AIDS and CD4 lymphocyte counts less than 200 x 10(6)/l than men. For every 100 AIDS patients seen in 1989, there were 88 non-AIDS patients with CD4 counts less than 500 x 10(6)/l, of whom 41 had CD4 counts less than 200 x 10(6)/l; thus, in addition to an estimated 16,425 individuals living with AIDS in NYC, we estimate that there are at least 14,454 HIV-infected individuals without AIDS with CD4 counts less than 500 x 10(6)/l, of whom 6734 have CD4 counts less than 200 x 10(6)/l. Men who have sex with men were significantly more likely to have Kaposi's sarcoma, cytomegalovirus disease and retinitis, cryptosporidiosis and lymphoma, and significantly less likely to have Pneumocystis carinii pneumonia, esophageal candidiasis, extrapulmonary tuberculosis (TB) and bacterial pneumonia than intravenous drug users. Whites were significantly less likely to have pulmonary TB than Hispanics, non-Haitian and Haitian blacks, toxoplasmosis than Hispanics and Haitian blacks, and salmonella septicemia than non-Haitian blacks. The frequencies of most diagnoses did not differ by sex; gynecologic diseases were recorded infrequently in the medical records of women in this study. CONCLUSIONS: These data indicate that there are more than 30,000 HIV-infected adults living in NYC with significant immunosuppression, that an increasing proportion of AIDS cases in NYC will occur among women, and that the spectrum of HIV-related disease varies markedly in different populations.     

The emergence of AIDS in Guatemala: inpatient experience at the Hospital General San Juan de Dios

Little is known about the effect of human immunodeficiency virus (HIV) infection on the Central American healthcare system. We describe HIV-related admissions in a Guatemalan medical service. The study was conducted at Guatemala City's largest public hospital. Data were derived from standardized data collection sheets maintained by the HIV testing service and by HIV clinic physicians. Data were collected for 295 medicine admissions of 257 HIV-infected adults during an 18-month period in 1999 and 2000; 30% of the patients were women. Average age was 33 years. Only 12.5% of the patients had been diagnosed with HIV infection prior to 1999 and nearly all had symptomatic AIDS. 60.3% of the patients were diagnosed with HIV infection during their hospitalization. The most common discharge diagnoses were tuberculosis (13.9%), toxoplasmosis, diarrhoea, candida and other fungal infections, and meningitis. Mean length of stay for HIV-positive patients was 17 days. 23.7% of the patients died during their hospitalization; this was double the mortality of non-HIV patients. HIV-infected patients represented 5.8% of the total admissions of the general medical wards. In a country where HIV prevalence is thought to be less than 1%, AIDS is now responsible for over 5% of admissions to a large medical service at a cost of $500,000 per year. These findings underline the importance of HIV infection in Central America and demonstrate the utility of tracking hospital admission data as a method of surveillance.     

Effect of hepatitis C infection on progression of HIV disease and early response to initial antiretroviral therapy

OBJECTIVES: To describe the effect of hepatitis C virus (HCV) on the progression of HIV disease and on early changes in the CD4 cell count and HIV viral load after HAART initiation. DESIGN AND METHODS: Data were from a longitudinal medical records review project conducted in over 100 US medical clinics from 1998 to 2004. We analysed data from HIV-infected patients who received antiretroviral therapy (ART), calculated adjusted hazard ratios describing the hazard of death or progression to an AIDS-defining opportunistic illness (AIDS-OI) associated with prevalent HCV infection, and estimated the change in CD4 cell count and HIV viral load after HAART initiation, stratified by HCV status. RESULTS: A total of 10 481 HIV-infected individuals were followed for a median of 1.9 years; 19% had HCV. HCV infection was not associated with progression to AIDS-OI or death after controlling for important confounding conditions. Factors significantly confounding the risk of both death and diagnosis of an AIDS-OI were alcoholism, drug-induced hepatitis, and the type of ART prescribed. Acute and chronic hepatitis B infection confounded the risk of AIDS-OI diagnosis. During the 12 months after starting HAART, proportional increases in CD4 cell counts did not differ between HCV-infected and HCV-uninfected individuals. Likewise, the short-term change in viral load did not differ. CONCLUSION: In our cohort, HCV did not increase the risk of death or AIDS-OI, and did not affect the early immunological or virological response to initial HAART. Clinicians should evaluate patients with HCV for other, manageable problems, including alcoholism and other viral hepatitis.     

Mortality and progression to AIDS after starting highly active antiretroviral therapy

OBJECTIVES: To examine survival and progression to AIDS among HIV-infected patients after starting highly active antiretroviral therapy (HAART). METHODS: The study population consisted of 3724 patients from the ATHENA observational cohort who initiated HAART. We considered progression to either an AIDS-defining disease or death, distinguishing HIV-related and non-related (including therapy-related) deaths. A time-dependent multivariate hazards model was fitted to the patient data and 5-year survival probabilities under various therapy scenarios estimated. RESULTS: A total of 459 patients developed AIDS and 346 died during 12 503 person-years of follow-up. HIV-related mortality decreased from 3.8 to 0.7 per 100 person-years between 1996 and 2000 whereas non-HIV-related mortality did not change (0.4 and 0.9, respectively, P = 0.25). For asymptomatic and symptomatic therapy naive patients younger than 50 years with CD4 counts above 10 x 10(6) and 150 x 10(6) cells/l, respectively, predicted 5-year survival probabilities were above 90% when HAART was used continuously. This limit was 450 x 10(6) cells/l when HAART was used during 20 weeks in each 24 week-period of follow-up, and 110 x 10(6) cells/l when patients delayed initiation of HAART for 1 year after becoming eligible for treatment. CONCLUSIONS: Survival probabilities were high among HIV-infected patients initiating HAART at an early stage of infection. The best therapy strategy is therefore to start HAART at this stage of infection. However, deferring HAART in patients with high CD4 cell counts may be clinically more appropriate given toxicity and adherence problems. The lack of any change in non-HIV-related mortality suggests that toxicity has not yet become a major risk factor for death.     

Opportunistic Infections and Other AIDS-defining Illnesses in Poland in 2000–2002

Abstract Background: The introduction of highly active antiretroviral therapy (HAART) led to a decreased incidence of the most severe opportunistic infections (OIs) in HIV-infected patients. In Poland, HAART became widely used in 1998. Materials and Methods: This study was based on data from medical records data collected in the years 2000–2002 from medical centers for HIV-infected patients in Poland. The aim of the study was to determine the incidence of opportunistic infections (OIs) and other AIDS defining illnesses (ADIs). The χ² test was used to determine any significant trends. Results: The incidence of ADIs was 6.8, 6.5 and 4.8/100 persons/year in 2000–2002, respectively. The most common diagnosed OIs were: fungal infections, tuberculosis, recurrent pneumonia, PCP and toxoplasmosis. In patients receiving HAART (HAART+) the incidence of ADIs was significantly lower than in non-ARV-treated as well as in all HIV+ (p < 0.02, p < 0.001, p < 0.001, respectively). A significant decrease in the incidence of ADIs in HAART+ patients between 2000 and 2002 (p < 0.0001) was observed. From 25% to 30% of ADIs among HAART+ patients were diagnosed within the first 3 months of antiretroviral therapy. In HAART+ patients the most common ADIs were fungal infections and tuberculosis. The diagnosis of ADIs resulted in the recognition of HIV status in 8.7–8.9% of patients. Conclusions: Five years after the introduction of HAART the incidence of ADIs had declined. Fungal infections and tuberculosis were the most common OIs in HIV+ patients in Poland.     

Survival of HIV-infected patients admitted to the intensive care unit in the era of highly active antiretroviral therapy

We retrospectively studied outcomes for HIV-infected patients admitted to the intensive care unit (ICU) between January 1999 and June 2009. Patient demographics, receipt of highly active antiretroviral therapy (HAART), reason for ICU admission and survival to ICU and hospital discharge were recorded. Comparison was made against outcomes for general medical patients contemporaneously admitted to the same ICU. One hundred and ninety-two HIV-infected patients had 222 ICU admissions; 116 patients required mechanical ventilation (MV) and 43 required renal replacement therapy. ICU admission was due to an HIV-associated diagnosis in 113 patients; 37 had Pneumocystis pneumonia. Survival to ICU discharge and hospital discharge for HIV-infected patients was 78% and 70%, respectively, and was 75% and 68% among 2065 general medical patients with 2274 ICU admissions; P = 0.452 and P = 0.458, respectively. HIV infection was newly diagnosed in 42 patients; their ICU and hospital survival was 69% and 57%, respectively. From multivariable analysis, factors associated with ICU survival were patient's age (odds ratio [OR] = 0.74 [95% confidence interval (CI) = 0.53-1.02] per 10-year increase), albumin (OR = 1.05 [1.00-1.09] per 1 g/dL increase), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR = 0.55 [0.35-0.87] per 10 unit increase), receipt of HAART (OR = 2.44 [1.01-4.94]) and need for MV (OR = 0.14 [0.06-0.36]). In the era of HAART, HIV-infected patients should be offered ICU admission if it is likely to be of benefit.
