RESUMO

This systematic review evaluates the association between religion, spirituality and clinical outcomes in HIV-infected individuals. A systematic literature review was conducted for all English language articles published between 1980 and 2016 in relevant databases. Six hundred fourteen studies were evaluated. 15 met inclusion criteria. Ten (67%) studies reported a positive association between religion or spirituality and a clinical HIV outcome. Two (13%) studies failed to detect such an association; and two (13%) demonstrated a negative association. One study (7%) identified features of religiosity and spirituality that had both negative and positive associations with HIV clinical outcomes. Recognizing the religious or spiritual commitments of patients may serve as an important component of patient care. Further longitudinal studies and interventions might be required to further clarify the potential impact of religion and spirituality on HIV clinical outcomes.

RESUMO

OBJECTIVES: Certain prescribed opioids have immunosuppressive properties, yet their impact on clinically relevant outcomes, including antiretroviral therapy (ART) response among HIV-infected patients, remains understudied. METHODS: Using the Veterans Aging Cohort Study data, we conducted a longitudinal analysis of 4358 HIV-infected patients initiating ART between 2002 and 2010 and then followed them for 24 months. The primary independent variable was prescribed opioid duration, categorized using pharmacy data as none prescribed, short-term (< 90 days) and long-term (≥ 90 days). Outcomes included CD4 cell count over time. Analyses adjusted for demographics, comorbid conditions, ART type and year of initiation, and overall disease severity [ascertained with the Veterans Aging Cohort Study (VACS) Index]. Sensitivity analyses examined whether effects varied according to baseline CD4 cell count, achievement of viral load suppression, and opioid properties (i.e. dose and known immunosuppressive properties). RESULTS: Compared to those with none, patients with short-term opioids had a similar increase in CD4 cell count (mean rise per year: 74 vs. 68 cells/µL; P = 0.11), as did those with long-term prescribed opioids (mean rise per year: 74 vs. 75 cells/µL; P = 0.98). In sensitivity analysis, compared with no opioids, the effects of short-term prescribed opioids were statistically significant among those with a baseline CD4 cell count ≥ 500 cells/µL (mean rise per year: 52 cells/µL for no opioids vs. 20 cells/µL for short-term opioids; P = 0.04); findings were otherwise unchanged. CONCLUSIONS: Despite immunosuppressive properties intrinsic to opioids, prescribed opioids appeared to have no effect on CD4 cell counts over 24 months among HIV-infected patients initiating ART.

RESUMO

OBJECTIVES: Community viral load (CVL) estimates vary based on analytic methods. We extended the CVL concept and used data from the Veterans Health Administration (VA) to determine trends in the health care system viral load (HSVL) and its sensitivity to varying definitions of the clinical population and assumptions regarding missing data. METHODS: We included HIV-infected patients in the Veterans Aging Cohort Study, 2000-2010, with at least one documented CD4 count, HIV-1 RNA or antiretroviral prescription (n = 37 318). We created 6-month intervals including patients with at least one visit in the past 2 years. We assessed temporal trends in clinical population size, patient clinical status and mean HSVL and explored the impact of varying definitions of the clinical population and assumptions about missing viral load. RESULTS: The clinical population size varied by definition, increasing from 16 000-19 000 patients in 2000 to 23 000-26 000 in 2010. The proportion of patients with suppressed HIV-1 RNA increased over time. Over 20% of patients had no viral load measured in a given interval or the past 2 years. Among patients with a current HIV-1 RNA, mean HSVL decreased from 97 800 HIV-1 RNA copies/mL in 2000 to 2000 copies/mL in 2010. When current HIV-1 RNA data were unavailable and the HSVL was recalculated using the last available HIV-1 RNA, HSVL decreased from 322 300 to 9900 copies/mL. HSVL was underestimated when using only current data in each interval. CONCLUSIONS: The CVL concept can be applied to a health care system, providing a measure of health care quality. Like CVL, HSVL estimates depend on definitions of the clinical population and assumptions about missing data.

RESUMO

OBJECTIVES: In HIV-uninfected populations, obstructive sleep apnoea (OSA) is commonly associated with cardiovascular disease, metabolic syndrome, and cognitive impairment. These comorbidities are common in HIV-infected patients, but there are scarce data regarding OSA in HIV-infected patients. Therefore, we examined the prevalence and correlates of OSA in a cohort of HIV-infected and uninfected patients. METHODS: An observational cohort study was carried out. Electronic medical record and self-report data were examined in patients enrolled in the Veterans Aging Cohort Study (VACS) between 2002 and 2008 and followed until 2010. The primary outcome was OSA diagnosis, determined using International Classification of Diseases, 9th edition (ICD-9) codes, in HIV-infected compared with uninfected individuals. We used regression analyses to determine the association between OSA diagnosis, symptoms and comorbidities in adjusted models. RESULTS: Of 3683 HIV-infected and 3641 uninfected patients, 143 (3.9%) and 453 (12.4%) had a diagnosis of OSA (p<0.0001), respectively. HIV-infected patients were more likely to report symptoms associated with OSA such as tiredness and fatigue. Compared with uninfected patients with OSA, HIV-infected patients with OSA were younger, had lower body mass indexes (BMIs), and were less likely to have hypertension. In models adjusting for these traditional OSA risk factors, HIV infection was associated with markedly reduced odds of OSA diagnosis (odds ratio 0.48; 95% confidence interval 0.39-0.60). CONCLUSIONS: HIV-infected patients are less likely to receive a diagnosis of OSA. Future studies are needed to determine whether the lower prevalence of OSA diagnoses in HIV-infected patients is attributable to decreased screening and detection or to a truly decreased likelihood of OSA in the setting of HIV infection.

RESUMO

Limited data exist on whether sexual partner notification practices among HIV-infected men, particularly those who have sex with men (MSM), vary by HIV viral load. We examined factors associated with complete (all partners) versus incomplete partner notification in 760 HIV-infected individuals across the United States, 49 % of whom were MSM. Thirty-four percent reported incomplete partner notification. Incomplete partner notification was more likely among black men, MSM, and those reporting casual partners and non-condom use. Partner notification practices did not vary by HIV viral load except among those with casual partners in whom a detectable viral load was associated with incomplete partner notification. Increased sexual partner notification among HIV-infected men, especially MSM, is needed.

RESUMO

BACKGROUND: While scholarship on alcohol use and homelessness has focused on the impact of alcohol abuse and dependence, little is known about the effects of lower levels of misuse such as hazardous use. Veterans receiving care in the Department of Veterans Affairs Health Care System (VA) constitute a population that is vulnerable to alcohol misuse and homelessness. This research examines the effects of hazardous drinking on homelessness in the Veterans Aging Cohort Study, a sample of 2898 older veterans (mean age=50.2), receiving care in 8 VAs across the country. METHODS: Logistic regression models examined the associations between (1) hazardous drinking at baseline and homelessness at 1-year follow-up, (2) transitions into and out of hazardous drinking from baseline to follow-up and homelessness at follow-up, and (3) transitioning to hazardous drinking and transitioning to homelessness from baseline to follow-up during that same time-period. RESULTS: After controlling for other correlates including alcohol dependence, hazardous drinking at baseline increased the risk of homelessness at follow-up (adjusted odds ratio [AOR]=1.39, 95% confidence interval [CI]=1.02, 1.88). Transitioning to hazardous drinking more than doubled the risk of homelessness at follow-up (AOR=2.42, 95% CI=1.41, 4.15), while more than doubling the risk of transitioning from being housed at baseline to being homeless at follow-up (AOR=2.49, 95% CI=1.30, 4.79). CONCLUSIONS: Early intervention that seeks to prevent transitioning into hazardous drinking could increase housing stability among veterans. Brief interventions which have been shown to be effective at lower levels of alcohol use should be implemented with veterans in VA care.

RESUMO

CONTEXT: Methadone maintenance is an effective treatment for opioid dependence, yet its use is restricted to federally licensed narcotic treatment programs (NTPs). Office-based care of stabilized methadone maintenance patients is a promising alternative but no data are available from controlled trials regarding this type of program. OBJECTIVE: To determine the feasibility and efficacy of office-based methadone maintenance by primary care physicians vs in an NTP for stable opioid-dependent patients. DESIGN: Six-month, randomized controlled open clinical trial conducted February 1999-March 2000. SETTING: Offices of 6 primary care internists and an NTP. PATIENTS: Forty-seven opioid-dependent patients who had been receiving methadone maintenance therapy in an NTP without evidence of illicit drug use for 1 year and without significant untreated psychiatric comorbidity were randomized; 1 patient refused to participate after treatment assignment to NTP. INTERVENTIONS: Patients were randomly assigned to receive office-based methadone maintenance from primary care physicians, who received specialized training in the care of opioid-dependent patients (n = 22), or usual care at an NTP (n = 24). MAIN OUTCOME MEASURES: Illicit drug use, clinical instability (persistent drug use), patient and clinician satisfaction, functional status, and use of health, legal, and social services, compared between the 2 groups. RESULTS: Eleven of 22 (50%; 95% confidence interval [CI], 29%-71%) patients in office-based care compared with 9 of 24 (38%; 95% CI, 21%-57%) of NTP patients had a self-report or urine toxicology test result indicating illicit opiate use (P =.39). Hair toxicology testing detected an additional 2 patients in each treatment group with evidence of illicit drug use, but this did not change the overall findings. Ongoing illicit drug use meeting criteria for clinical instability occurred in 4 of 22 (18%; 95% CI, 7%-39%) patients in office-based care compared with 5 of 24 (21%; 95% CI, 9%-41%) NTP patients (P =.82). Sixteen of the 22 (73%; 95% CI, 54%-92%) office-based patients compared with 3 of the 24 (13%; 95% CI, 0%-26%) NTP patients thought the quality of care was excellent (P =.001). There were no differences over time within or between groups in functional status or use of health, legal, or social services. CONCLUSIONS: Our results support the feasibility and efficacy of transferring stable opioid-dependent patients receiving methadone maintenance to primary care physicians' offices for continuing treatment and suggest guidelines for identifying patients and clinical monitoring.

RESUMO

Illicit drug use is an important public health problem with broad social costs. The low effectiveness of prevention efforts leaves treatment of drug dependence as one of the most powerful means of fighting illicit drug use. Treatment reduces drug use and crime and increases individuals' functioning. However, programs that treat drug dependence have high dropout rates and low completion rates. In addition, some individuals continue to use drugs while in treatment, and relapse is common. Furthermore, only a fraction of those who need treatment receive it. Recently, there have been important innovations that reduce barriers and increase effectiveness of treatment. These innovations include new pharmacological agents, novel counseling strategies, promising ways to motivate, and treatment in new settings. This paper describes standard treatments and recent innovations designed to increase (a) effectiveness of treatment, (b) motivation to seek care, (c) access, (d) retention, and (e) cost-effectiveness. We provide criteria on how these innovations should be evaluated in order to determine which should be adopted, funded, and transferred to existing and future treatment programs.

RESUMO

This paper addresses the clinical presentation of patients with alcohol problems including screening, diagnosis, detoxification, treatment, referral, and longitudinal follow-up. The case-based discussion focuses on the clinical management of a patient whose hazardous drinking progresses to alcohol dependence and requires coordinated care. Ways in which internists can aid patients with alcohol problems by screening, giving brief advice, and providing appropriate referrals when indicated are discussed.

RESUMO

OBJECTIVE: To assess reasons why patients undergo elective percutaneous coronary revascularization (PCR), patient expectations of the benefits of PCR, and their understanding of the risks associated with PCR. We hypothesized that patients overestimate the benefits and underestimate the risks associated with PCR. DESIGN: A prospective, semistructured questionnaire. PARTICIPANTS: Patients undergoing their first elective PCR. MAIN RESULTS: Fifty-two consecutive patients with a mean age of 64.3 years (range 39-87) completed the interview. Although 30 (57%) patients cited relief of symptoms as at least 1 reason to have PCR, 32 (62%) patients cited either an abnormal diagnostic test result (i.e., exercise stress test or catheterization) or "pathophysiologic" problem (i.e., "I have a blockage"), with 17 patients (33%) citing these reasons alone as indications for PCR. Thirty-nine (75%) patients believed PCR would prevent a future myocardial infarction, and 37 (71%) patients felt PCR would prolong their life. Regarding the potential complications, only 24 patients (46%) could recall at least 1 possible complication. However, on a Deber questionnaire, the majority of patients (67%) stated that they should determine either mostly alone or equally with a physician how acceptable the risks of the procedure are for themselves. CONCLUSIONS: The majority of patients had unrealistic expectations about the long-term benefits of elective PCR and was not aware of the potential risks, even though they expressed a strong interest in participating in the decision to have PCR. More work is needed to define the optimal strategy to educate patients about the benefits and risks of elective PCR, and whether such education will affect patient decision making.

RESUMO

Patients with heroin dependence frequently present to internists and other physicians for heroin-related medical, psychiatric, and behavioral health problems and often seek help with reducing their heroin use. Thus, physicians should be familiar with the identification and diagnosis of heroin dependence in their patients and be able to initiate treatment of heroin dependence both directly and by referral. Recent research has provided much information concerning effective pharmacologically based treatment approaches for managing opioid withdrawal and helping patients to remain abstinent Methadone maintenance and newer approaches using L-alpha acetylmethadol and buprenorphine seem to be particularly effective in promoting relapse prevention. Although these treatments are currently provided in special drug treatment settings, recent and ongoing research indicates that the physician's office may be an effective alternative site for these treatments.

RESUMO

BACKGROUND: Primary care physicians can play a unique role in recognizing and treating patients with alcohol problems. OBJECTIVE: To evaluate the accuracy of screening methods for alcohol problems in primary care. METHODS: We performed a search of MEDLINE for years 1966 through 1998. We included studies that were in English, were performed in primary care, and reported the performance characteristics of screening methods for alcohol problems against a criterion standard. Two reviewers appraised all articles for methodological content and results. RESULTS: Thirty-eight studies were identified. Eleven screened for at-risk, hazardous, or harmful drinking; 27 screened for alcohol abuse and dependence. A variety of screening methods were evaluated. The Alcohol Use Disorders Identification Test (AUDIT) was most effective in identifying subjects with at-risk, hazardous, or harmful drinking (sensitivity, 51%-97%; specificity, 78%-96%), while the CAGE questions proved superior for detecting alcohol abuse and dependence (sensitivity, 43%-94%; specificity, 70%-97%). These 2 formal screening instruments consistently performed better than other methods, including quantity-frequency questions. The studies inconsistently adhered to methodological standards for diagnostic test research: 3 (8%) provided a full description of patient spectrum (demographics and comorbidity), 30 (79%) avoided workup bias, 12 (of 34 studies [35%]) avoided review bias, and 21 (55%) performed an analysis in pertinent clinical subgroups. CONCLUSIONS: Despite methodological limitations, the literature supports the use of formal screening instruments over other clinical measures to increase the recognition of alcohol problems in primary care. Future research in this field will benefit from increased adherence to methodological standards for diagnostic tests.

RESUMO

Primary care physicians are frequently involved in the longitudinal care of patients with alcohol problems and in helping patients to decrease their alcohol consumption. Recent clinical trials provide evidence in support of new treatment strategies for these patients. Brief interventions have been used successfully to reduce alcohol consumption in patients with hazardous and harmful drinking. Twelve-step facilitation, cognitive behavioral, and motivational enhancement therapies have produced sustained drinking reductions in patients with alcohol dependence. Pharmacologic therapies, such as naltrexone and acamprosate, have been effective in decreasing alcohol consumption when provided along with psychosocial counseling in patients with alcohol dependence. The current review highlights the application of these new therapies to primary care physicians' efforts on behalf of their patients with alcohol problems.

RESUMO

BACKGROUND: Educational experiences in ambulatory medicine vary by site. PURPOSE: To evaluate variations in patient mix and challenges in patient care at 3 ambulatory training sites. METHOD: Patients (n=123) receiving care at a VA medical center (VA), an urban academic medical center's primary care center (PCC), and a community group practice (CGP) were evaluated. RESULTS: Patients at the VA (n=55), compared with those at the PCC (n=44) and the CGP (n=24), were older, more likely to be male, and white (all P<0.05). Patients at the VA and the PCC reported difficulty with functional and health status more frequently than those at the CGP (all P<0.05). Common medical diagnoses varied across sites and comorbidity scores were > or = 2 in 48% of VA subjects compared with 16% at the PCC and 29% at the CGP (P<0.05). Challenges most frequently cited were administrative issues at the VA (44%), patient-physician communication at the PCC (39%), and medical decisions at the CGP (50%) (P<0.05). CONCLUSIONS: Ambulatory training sites can differ greatly with respect to characteristics beyond diagnosis. Plans for increased and improved ambulatory training of internal medicine residents should include attention to these issues to ensure exposure to an adequate patient spectrum.

RESUMO

The objective of this study was to determine if increased alcohol exposure is associated with greater use of health services among older veterans. A total of 129 older veterans (> or =65 years old), receiving longitudinal care in a Veterans' Administration primary care clinic, were followed retrospectively for up to 42 months. Subjects were screened at baseline for problem drinking with the CAGE or the quantity-frequency questions from the Alcohol Use Disorders Identification Test (QF-AUDIT), and stratified by exposure into three categories: abstainers, social drinkers, and problem drinkers. Outcomes included total outpatient clinic visits, laboratory tests, radiologic and other technologic procedures, as well as acute care hospitalizations. For all subjects (N = 129), no association was found between alcohol exposure and use of any outpatient services. Among CAGE-screened (n = 62) abstainers, social drinkers, and problem drinkers, significant differences were found in the median number of laboratory tests (7.3 vs. 3.4 vs. 7.1, P = 0.004) and hospitalizations (0.3 vs. 0.0 vs. 0.3, P = 0.001) per patient year of follow-up. No exposure-outcome associations were present, however, among QF-AUDIT-screened subjects (n = 67). We were unable to demonstrate a consistent relationship between alcohol exposure and health services utilization. The effects of alcohol on older veterans' use of health services varied with the method used to measure alcohol exposure. Additional studies are needed to determine whether multiple, or possibly new, measures can more precisely define the health effects of alcohol in older populations.

RESUMO

Increasing emphasis has been placed on the detection and treatment of hazardous and harmful drinking disorders, particularly among patients who are seen in primary care settings. In this review, we summarize the epidemiology and health-related effects of hazardous and harmful drinking and discuss current methods for their detection and treatment. Hazardous drinking is defined as a quantity or pattern of alcohol consumption that places patients at risk for adverse health events, while harmful drinking is defined as alcohol consumption that results in adverse events (e.g., physical or psychological harm). Prevalence estimates range from 4% to 29% for hazardous drinking and from less than 1% to 10% for harmful drinking. Data from several recent large prospective studies suggest that alcohol consumption in quantities consistent with hazardous or harmful drinking may increase risk for adverse health events, such as hemorrhagic stroke and breast cancer. Existing screening instruments, such as the Michigan Alcoholism Screening Test (MAST) or the CAGE questionnaire, while excellent for detecting alcohol abuse or dependence, should not be used alone to screen for hazardous and harmful drinking. The Alcohol Use Disorders Identification Test (AUDIT) is currently the only instrument specifically designed to identify hazardous and harmful drinking. Treatment of these disorders in the form of brief interventions can be successfully accomplished in primary care settings, as demonstrated by a number of well-conducted randomized trials. Given its proven efficacy in the primary care setting, we recommend routine application of this treatment approach.

RESUMO

Patients with moderately severe or severe alcoholic hepatitis, described in a companion paper in this issue, had serial studies of energy and protein metabolism and elemental balances before and during treatment for 21 days with one of four randomly assigned regimens: 1) standard therapy, consisting of abstinence, a balanced, nutritionally adequate diet, and multivitamins; 2) oxandrolone (20 mg orally four times a day) plus standard therapy; 3) nutritional supplementation, consisting of 2 liters of 3.5% crystalline amino acids in 5% dextrose given by peripheral vein (PPN) plus standard therapy; and 4) a combination of the other three treatments. Dietary and intravenous intakes and weights were recorded daily, and weekly averages were calculated. Anthropometric measurements and blood studies were done weekly; blood studies included white blood cell counts and differentials, serum prealbumin, transferrin, and total protein and plasma aminograms. Four-days complete balance studies and measures of 15N,1-13C-leucine metabolism also were performed at baseline and after the treatment period. Major findings were as follows: a) Intakes of total calories and protein were significantly higher in PPN-treated than in other groups. b) All patients had positive elemental balances, both at baseline and at the end of the treatment period. However, those treated with PPN (with or without oxandrolone) had higher positive balances of nitrogen, potassium, phosphorus, and magnesium, indicating improvement in lean body mass. c) Anthropometric measurements showed no significant changes, but measures of the visceral protein compartment (serum prealbumin, transferrin, total protein, total lymphocyte count) improved significantly with time. For most of these variables, increases were significantly greater in those treated with PPN with or without oxandrolone than in the other groups. However, for prealbumin, the increase was greatest in the oxandrolone-treated group d) PPN treatment produced dramatic increases in levels of branched-chain amino acids and improvement in the ratio of plasma branched chain to aromatic amino acids. Other treatments had no effect on plasma aminograms. e) Metabolism of 15N,1-13C-leucine was normal and was not affected significantly by treatment. Therapy with PPN and/or oxandrolone was tolerated well. We conclude that PPN has favorable effects on energy and protein metabolism in florid alcoholic hepatitis; oxandrolone has lesser effects, although it may exert some additional action and particularly increases serum prealbumin levels. The results support the use of nutritional supplementation in therapy of moderately severe or severe alcoholic hepatitis.

RESUMO

The present studies were designed to provide careful measures of effects of oxandrolone, an anabolic steroid, intravenous nutritional supplementation, and the combination of these two treatments on liver functions, metabolic balances, nitrogen metabolism, and nutritional status in patients with moderate to severe alcoholic hepatitis. Of 43 patients originally recruited, 39 (19 men, 20 women) with typical clinical and laboratory features of alcoholic hepatitis (11 Child's-Pugh class B; 28 class C) were admitted to a metabolic unit and completed a 35-day three-phase protocol. Phase I was a 10-day baseline period of observation, during which routine and special quantitative tests of liver function (galactose and antipyrine metabolism), a 7-day elemental balance study, and a 15N, 13C-leucine metabolism study were done. Phase II was a 21-day treatment period during which patients were randomly assigned to receive one of four regimens: 1) standard therapy, consisting of abstinence, a balanced, nutritionally adequate diet, and multivitamins; 2) oxandrolone (20 mg orally four times a day) plus standard therapy; 3) nutritional supplementation, consisting of 2 L daily of 3.5% crystalline amino acids (in 5% dextrose), given by peripheral vein; or 4) a combination of oxandrolone and nutritional supplementation, along with standard therapy. Metabolic balances were repeated during phase II. Phase III was 2 or 3 days posttreatment, during which special studies of liver functions and volumes and leucine metabolism were repeated. All patients who completed phase I of study and were randomly allocated to one of the four treatment groups completed the subsequent two phases. Overall, with time, patients showed highly significant improvements in most clinical and laboratory features. For most standard laboratory tests (e.g., serum albumin, transferrin, prothrombin time) improvements were more marked in patients treated with nutritional supplementation and/or oxandrolone than in those given standard therapy alone. Liver volumes fell in all treatment groups, with greater improvement in those treated with nutritional supplementation. Improvements in galactose and antipyrine metabolism rates were significant only in those treated with nutritional supplementation or oxandrolone. Effects of treatments on metabolic balances, nitrogen metabolism, and measures of nutrition are described in this issue in a companion paper. We conclude that the addition of nutritional supplementation and oxandrolone to standard therapy of moderately severe or severe alcoholic hepatitis is well tolerated, and leads to more rapid improvement in the laboratory parameters measured.
