RESUMEN

Background: In 2010-2014, the San Francisco Department of Public Health (SFDPH) established programs to rapidly link people with human immunodeficiency virus (PWH) to care and offer antiretroviral therapy (ART) at human immunodeficiency virus (HIV) diagnosis. Such programs reduced the number of PWH out of care or with detectable HIV viral load (ie, uncontrolled HIV infection). We investigated the role of social determinants of health (SDH) on uncontrolled HIV. Methods: Cross-sectional data from adult PWH diagnosed and reported to the SFDPH as of December 31, 2019, prescribed ART, and with confirmed San Francisco residency during 2017-2019 were analyzed in conjunction with SDH metrics derived from the American Community Survey 2015-2019. We focused on 5 census tract-level SDH metrics: percentage of residents below the federal poverty level, with less than a high school diploma, or uninsured; median household income; and Gini index. We compared uncontrolled HIV prevalence odds ratios (PORs) across quartiles of each metric independently using logistic regression models. Results: The analysis included 7486 PWH (6889 controlled HIV; 597 uncontrolled HIV). Unadjusted PORs of uncontrolled HIV rose with increasingly marginalized quartiles, compared to the least marginalized quartile for each metric. Adjusting for demographics and transmission category, the POR for uncontrolled HIV for PWH in the most marginalized quartile remained significant across metrics for poverty (POR = 2.0; confidence interval [CI] = 1.5-2.6), education (POR = 2.4; CI = 1.8-3.2), insurance (POR = 1.8; CI = 1.3-2.5), income (POR = 1.8; CI = 1.4-2.3), and income inequality (POR = 1.5; CI = 1.1-2.0). Conclusions: Beyond demographics, SDH differentially affected the ability of PWH to control HIV. Despite established care programs, PWH experiencing socioeconomic marginalization require additional support to achieve health outcome goals.

RESUMEN

The HIV-1 epidemic in the US has historically been dominated by subtype B. HIV subtype diversity has not been extensively examined in most US cities to determine whether non-B variants have become established, as has been observed in many other global regions. We describe the diversity of non-B variants and present evidence of local transmission of non-B HIV in San Francisco. Viral sequences collected from patients between 2000 and 2016 were matched to the San Francisco HIV/AIDS case registry. HIV subtype was determined using COMET. Phylogenies were reconstructed using the pol region of subtypes A, C, D, G, CRF01_AE, CRF02_AG, and CRF07_BC, with reference sequences from the LANL HIV database. Associations of non-B subtypes and circulating recombinant forms (CRFs) with patient characteristics were assessed using multivariable logistic regression. Out of 11,381 sequences, 10,669 were from 7235 registry cases, of which 141 (2%) had non-B subtypes and CRFs and 72 (1%) had unique recombinant forms. CRF01_AE (0.8%) and subtype C (0.5%) were the most prevalent non-B forms. The frequency of non-B subtypes and CRFs increased in San Francisco during years 2000-2016. Out of 146 transmission events involving non-B study sequences, 18% indicated local transmission within the study population and 74% appeared to be inward migration of the virus. Compared to 7016 cases with only subtype B, 141 cases with non-B sequences were more likely to be of non-US country of birth (aOR = 11.02; p < 0.001), of Asian/Pacific-Islander race/ethnicity (aOR = 3.17; p < 0.001), and diagnosed after 2009 (aOR = 4.81; p < 0.001). Results suggest that most non-B infections were likely acquired outside the US and that local transmission of non-B forms has occurred but so far has not produced extensive transmission networks. Thus, non-B variants were not widely established in San Francisco, an observation that differs from cities worldwide with more diverse epidemics.

RESUMEN

Mixed methods studies of human disease that combine surveillance, biomarker, and qualitative data can help elucidate what drives epidemiological trends. Viral genetic data are rarely coupled with other types of data due to legal and ethical concerns about patient privacy. We developed a novel approach to integrate phylogenetic and qualitative methods in order to better target HIV prevention efforts. The overall aim of our mixed methods study was to characterize HIV transmission clusters. We combined surveillance data with HIV genomic data to identify cases whose viruses share enough similarities to suggest a recent common source of infection or participation in linked transmission chains. Cases were recruited through a multi-phase process to obtain consent for recruitment to semi-structured interviews. Through linkage of viral genetic sequences with epidemiological data, we identified individuals in large transmission clusters, which then served as a sampling frame for the interviews. In this article, we describe the multi-phase process and the limitations and challenges encountered. Our approach contributes to the mixed methods research field by demonstrating that phylogenetic analysis and surveillance data can be harnessed to generate a sampling frame for subsequent qualitative data collection, using an explanatory sequential design. The process we developed also respected protections of patient confidentiality. The novel method we devised may offer an opportunity to implement a sampling frame that allows for the recruitment and interview of individuals in high-transmission clusters to better understand what contributes to spread of other infectious diseases, including COVID-19.

RESUMEN

BACKGROUND: San Francisco has implemented several programs addressing the needs of two large vulnerable populations: people living with HIV and those who are homeless. Assessment of these programs on health outcomes is paramount for reducing preventable deaths. METHODS: Individuals diagnosed with HIV/AIDS and reported to the San Francisco Department of Public Health HIV surveillance registry, ages 13 years or older, who resided in San Francisco at the time of diagnosis, and who died between January 1, 2002, and December 31, 2016 were included in this longitudinal study. The primary independent variable was housing status, dichotomized as ever homeless since diagnosed with HIV, and the dependent variables were disease-specific causes of death, as noted on the death certificate. The Cochran-Armitage test measured changes in the mortality rates over time and unadjusted and adjusted Poisson regression models measured prevalence ratios (PR) and 95% confidence intervals (CI) for causes of death. RESULTS: A total of 4158 deceased individuals were included in the analyses: the majority were male (87%), ages 40-59 years old at the time of death (64%), non-Hispanic White (60%), men who have sex with men (54%), had an AIDS diagnosis prior to death (87%), and San Francisco residents at the time of death (63%). Compared to those who were housed, those who were homeless were more likely to be younger at time of death, African American, have a history of injecting drugs, female or transgender, and were living below the poverty level (all p values < 0.0001). Among decedents who were SF residents at the time of death, there were declines in the proportion of deaths due to AIDS-defining conditions (p < 0.05) and increases in accidents, cardiomyopathy, heart disease, ischemic disease, non-AIDS cancers, and drug overdoses (p < 0.05). After adjustment, deaths due to mental disorders (aPR = 1.63, 95% CI 1.24, 2.14) were more likely and deaths due to non-AIDS cancers (aPR = 0.63, 95% CI 0.44, 0.89) were less likely among those experiencing homelessness. CONCLUSIONS: Additional efforts are needed to improve mental health services to homeless people with HIV and prevent mental-health related mortality.

RESUMEN

OBJECTIVE: We explored potential HIV transmission typologies that involve transgender women to obtain insights on sexual and needle-sharing networks as sources of HIV infection. DESIGN: San Francisco residents diagnosed with HIV in care at public facilities who had available viral pol sequences from June 2001 to January 2016 were included in the analysis. METHODS: Viral sequence data were matched to the San Francisco HIV/AIDS Case Registry to obtain demographic and risk classification information. Transmission clusters with at least two cases were identified by bootstrap values at least 90% and mean pairwise genetic distances 0.025 or less substitutions per site. RESULTS: Transgender women represented 275 of 5200 patients; 86 were present in 70 clusters. Four typologies were hypothesized: first, transgender women in clusters with MSM; second, transgender women who inject drugs in clusters with cisgender women and men who inject drugs; third, multiple transgender women in clusters with one man; and fourth, multiple transgender women who do not inject drugs in clusters with men and cisgender women who inject drugs. CONCLUSION: Transmission patterns of transgender women may stand apart from MSM epidemics. Transgender women clustered with people who inject drugs, and with men who have sex with transgender women and cisgender women. Aggregation of transgender women into the category of MSM may obscure understanding of how they acquire HIV and to whom they may transmit infection. Phylogenetic insights strengthen the case that HIV prevention programs for MSM may not be applicable to transgender women or their partners.

RESUMEN

OBJECTIVE: San Francisco, California, has experienced a 44% reduction in new HIV diagnoses since 2013 supported by its 'Getting to Zero' initiative; however, the age-adjusted mortality rate in people with HIV (PWH) has not decreased. We sought to identify factors associated with death among PWH in San Francisco. DESIGN: Population-based incidence-density case-control study. METHODS: Among PWH in the San Francisco HIV surveillance registry, a random sample of 48 decedents from 1 July 2016 to 31 May 2017 were each matched to two to three controls who were alive at the date of death (108 controls matched on age and time since diagnosis). Covariates included demographics, substance use, housing status, medical conditions, and care indicators from the study population. We used matched-pair conditional logistic regression to examine factors associated with mortality. RESULTS: Of the 156 PWH in the study, 14% were African-American, 14% Latino, and 8% female sex. In adjusted analysis, factors associated with higher odds of death included: homelessness at HIV diagnosis [adjusted odds ratio (AOR) = 27.4; 95% confidence interval (CI) = 3.0-552.1], prior-year IDU (AOR = 10.2; 95% CI = 1.7-128.5), prior-year tobacco use (AOR = 7.2; 95% CI = 1.7-46.9), being off antiretroviral therapy at any point in the prior year (AOR = 6.8; 95% CI = 1.1-71.4), and being unpartnered vs. married/partnered (AOR = 4.7; 95% CI = 1.3-22.0). CONCLUSION: People homeless at HIV diagnosis had 27-fold higher odds of death compared with those with housing; substance use and retention on antiretroviral therapy in the prior year are other important intervenable factors. New strategies to address these barriers, and continued investment in supportive housing and substance use treatment, are needed.

RESUMEN

BACKGROUND: Early initiation of antiretroviral therapy (eiART) can improve clinical outcomes for persons with HIV and reduce onward transmission risk. Baseline drug resistance testing (bDRT) can inform regimen selection upon subsequent treatment initiation. We examined the uptake of eiART and bDRT within 3 months and 30 days of HIV diagnosis. METHODS: We analyzed a population-based sample from the San Francisco Department of Public Health HIV/AIDS Case Registry of newly-diagnosed HIV/non-AIDS individuals between 2001 and 2015 who received care at publicly-funded facilities (N = 3,124). RESULTS: Uptake of eiART within 3 months of diagnosis increased significantly from 2001 to 2015 (p<0.001), peaking at 74% in 2015. bDRT uptake also increased significantly (p<0.001), peaking at 55% in 2012. eiART uptake was observed to be significantly associated with gender, age, race/ethnicity and transmission risk. There were no significant differences observed in demographic and risk characteristics of persons receiving bDRT in the more recent years. Of 990 persons diagnosed between 2010 and 2015, eiART uptake within 30 days of diagnosis increased from 13% to 38% (p<0.001); bDRT uptake increased from 35% to 39% but the change was not significant (p = 0.141). CONCLUSIONS: Observed increases in eiART and bDRT uptake from 2010 to 2015 may reflect the adoption of treatment as prevention and a local public health policy statement in 2010 recommending treatment initiation at time of diagnosis irrespective of CD4 count. Concerns about stigma may underlie disparities in eiART, however such concerns would not bear as directly on a provider-initiated laboratory test like bDRT.

RESUMEN

Background: San Francisco has launched interventions to reduce new human immunodeficiency virus (HIV) infections and HIV-associated morbidity and mortality during the San Francisco "Getting to Zero" era. We measured recent changes in HIV care indicators to assess the success of these interventions. Methods: San Francisco residents with newly diagnosed HIV infection, diagnosed from 2009 to 2014, were included. We measured temporal changes from HIV diagnosis to (1) linkage to care in within ≤3 months, (2) initiation of antiretroviral therapy (ART) within ≤12 months, (3) viral suppression within ≤12 months, (4) development of AIDS within ≤3 months, (5) death within ≤12 months, and (6) retention in care 6-12 months after linkage. Kaplan-Meier analyses stratified by year of HIV diagnosis measured time from diagnosis to linkage, ART initiation, viral suppression, AIDS, and death. Results: Overall, the number of new diagnoses declined from 473 in 2009 to 329 in 2014. The proportion of new diagnoses among men (P = .005), Latinos and Asian/Pacific Islanders (P = .02), and men who have sex with men (P = .003) increased. ART initiation and viral suppression ≤12 months after diagnosis increased (P < .001), while the proportion with AIDS diagnosed ≤3 months after HIV diagnosis declined (P < .001). Time to ART initiation and time to viral suppression were significantly shorter in more recent years of diagnosis (P < .001). Time from HIV to AIDS diagnosis was significantly longer in more recent years (P < .001). Retention in care did not significantly change. Conclusions: In San Francisco new HIV diagnoses have declined and HIV care indicators have improved during the Getting to Zero era. Continued success requires attention to vulnerable populations and monitoring to adjust programmatic priorities.

RESUMEN

There were 1311 newly diagnosed HIV cases in San Francisco between 2005 and 2011 that were linked to care at publicly funded facilities and had viral sequences available for analysis. Of the 214 cases characterized as recently infected with HIV at the time of diagnosis, 25% had a recent sexually transmitted infection diagnosis (vs. 10% among longer-standing HIV infections, P < 0.001) and 57% were part of a phylogenetic transmission cluster (vs. 42% among longer-standing HIV infection, P < 0.001). The association observed between recent HIV infection and having a sexually transmitted infection diagnosis during the interval overlapping likely HIV acquisition points to potential opportunities to interrupt HIV transmission.

RESUMEN

OBJECTIVES: To describe the epidemiology of people coinfected with hepatitis B virus (HBV) or hepatitis C virus (HCV) and HIV in San Francisco, the San Francisco Department of Public Health's Communicable Disease Control and Prevention Section and the HIV Epidemiology Section collaborated to link their registries. METHODS: In San Francisco, hepatitis reporting is primarily through passive laboratory-based surveillance, and HIV/AIDS reporting is primarily through laboratory-initiated active surveillance. We conducted the registry linkage in 2010 using a sequential algorithm. RESULTS: The registry match included 31,997 HBV-infected people who were reported starting in 1984; 10,121 HCV-infected people who were reported starting in 2001; and 34,551 HIV/AIDS cases reported beginning in 1981. Of the HBV and HCV cases, 6.3% and 12.6% were coinfected with HIV, respectively. The majority of cases were white males; however, black people were disproportionately affected. For more than 90% of the HBV/HIV cases, male-to-male sexual contact (men who have sex with men [MSM]) was the risk factor for HIV infection. Injection drug use was the most frequent risk factor for HIV infection among the HCV/HIV cases; however, 35.6% of the HCV/HIV coinfected males were MSM but not injection drug users. CONCLUSIONS: By linking the two registries, we found new ways to foster collaborative work and expand our programmatic flexibility. This analysis identified particular populations at risk for coinfection, which can be used by viral hepatitis and HIV screening, prevention, and treatment programs to integrate, enhance, target, and prioritize prevention services and clinical care within the community to maximize health outcomes.

RESUMEN

OBJECTIVE: AIDS-related primary central nervous system lymphoma (AR-PCNSL) has a poor prognosis. Improved understanding of specific patient, infectious, diagnostic, and treatment-related factors that affect overall survival (OS) is required to improve outcomes. DESIGN: Population-based registry linkage study. METHODS: Adult cases from the San Francisco AIDS registry (1990-2000) were matched with the California Cancer Registry (1985-2002) to ascertain AR-PCNSL data. Survival time was assessed through 31 December 2007. Risk factors and temporal trends for death were measured using two-sided Kaplan-Meier and Cox analyses. RESULTS: Two hundred and seven AR-PCNSL patients were identified: 68% were white, 20% Hispanic, 10% African-American, and 2% Asian. Nineteen percent of patients had central nervous system (CNS) opportunistic infections diagnosed prior to AR-PCNSL. Fifty-seven percent of patients received radiation and/or chemotherapy and 12% used HAART prior to or within 30 days of AR-PCNSL diagnosis. One hundred and ninety-nine patients died (34 deaths/100 person-years). In adjusted analysis, prior CNS opportunistic infection diagnosis increased risk of death (hazard ratio 1.9, P = 0.0006) whereas radiation and/or chemotherapy decreased risk (hazard ratio 0.6, P < 0.0001). AR-PCNSL diagnosis 1999-2002 had a lower mortality risk (hazard ratio = 0.4, P = 0.02) compared to 1990-1995. African-Americans had an increased risk of death compared to whites or Asians (hazard ratio = 2.0, P = 0.007). CONCLUSION: OS among AR-PCNSL patients improved over time but remains poor, especially among African-Americans. Prospective evaluation of curative therapy in AR-PCNSL is urgently needed. Accurate diagnosis of CNS mass lesions in patients with AIDS is required and for those with AR-PCNSL, antiretroviral therapy with concomitant AR-PCNSL therapy, and antimicrobial supportive care may improve OS.

RESUMEN

BACKGROUND: Men who have sex with men (MSM) who have a current or recent history of rectal Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) infection are at greater risk for HIV than MSM with no history of rectal infection. Screening and treating MSM for rectal CT/GC infection may help reduce any increased biological susceptibility to HIV infection. METHODS: We used 2 versions of a Markov state-transition model to examine the impact and cost-effectiveness of screening MSM for rectal CT/GC infection in San Francisco: a static version that included only the benefits to those screened and a dynamic version that accounted for population-level impacts of screening. HIV prevention through reduced susceptibility to HIV was the only potential benefit of rectal CT/GC screening that we included in our analysis. Parameter values were based on San Francisco program data and the literature. RESULTS: In the base case, the cost per quality-adjusted life year gained through screening MSM for rectal CT/GC infection was $16,300 in the static version of the model. In the dynamic model, the cost per quality-adjusted life year gained was less than $0, meaning that rectal screening was cost-saving. The impact of rectal CT/GC infection on the risk of HIV acquisition was the most influential model parameter. CONCLUSIONS: Although more information is needed regarding the impact of rectal CT/GC screening on HIV incidence, rectal CT/GC screening of MSM can potentially be a cost-effective, scalable intervention targeted to at-risk MSM in certain urban settings such as San Francisco.

RESUMEN

We use HIV testing history of persons newly diagnosed with HIV through HIV partner services to identify persons who might not otherwise have tested. Seventeen percent had never been tested, 44% had not been tested in the previous 2 years, and none had been tested routinely. These data demonstrate that HIV partner services were successful in reaching persons who may not have initiated testing without this service.

RESUMEN

People aged 50 and older are an increasing proportion of the population of persons living with AIDS (PLWA) in the USA. We used San Francisco's population-based HIV/AIDS surveillance registry to examine trends in the age distribution of people diagnosed and living with AIDS in San Francisco, California. AIDS case reporting is highly complete. Death ascertainment is complete through 2009 and 95% complete for 2010. At the end of 2010, 9796 persons were living with AIDS in San Francisco. Of these, more than half (5112 or 52%) were 50-years old or older. This proportion has steadily increased since 1990 in San Francisco. Our data also indicate that age at AIDS diagnosis has increased in San Francisco during the years 1990-2010. The proportion of PLWA who are aged 50 years or older is now a majority among PLWA in San Francisco. We believe that San Francisco is the first local jurisdiction in the USA to reach this milestone. The growing population of older persons with AIDS presents new challenges for research, medical care and support services.

RESUMEN

We used data from HIV/AIDS surveillance case registry to assess the timing of entry into medical care, level of care received after HIV diagnosis, and to identify characteristics associated with delayed and insufficient care among persons diagnosed with HIV/AIDS between 2006 and 2007 in San Francisco. Laboratory reports of HIV viral load and CD4 test results were used as a marker for receipt of medical care. The time from HIV diagnosis to entry into care was estimated using Kaplan-Meier product limit method and independent predictors of delayed entry into care were determined using the proportional hazards model. Insufficient care was defined as less than an average of two viral load/CD4 tests per person-year of follow-up. Predictors of insufficient care were evaluated using a logistic regression model. An estimated 85% of persons diagnosed with HIV/AIDS entered care within three months after HIV diagnosis; the proportion increased to 95% within 12 months after diagnosis. Persons who were born outside of the USA and those tested at the public counseling and testing sites were more likely to delay care. Nineteen percent of persons were determined to have received insufficient care. Younger persons and those diagnosed at a hospital were more likely to receive insufficient care. A high proportion of persons diagnosed with HIV/AIDS in San Francisco established timely and adequate care after HIV diagnosis. However, delays for some individuals in entry into care and markers of insufficient care suggest that there remains a need to improve access to and sustainability of HIV-specific medical care.

RESUMEN

OBJECTIVES: To assess the impact of HAART use on AIDS-defining Kaposi's sarcoma and non-Hodgkin lymphoma (NHL) among adults with AIDS. DESIGN: Registry linkage study. METHODS: Adults diagnosed with AIDS from 1990 to 2000 in the San Francisco AIDS case registry were matched with cancer cases diagnosed from 1985 to 2002 in the California Cancer Registry. Multivariate Cox proportional hazard models were used to evaluate the risk and survival of AIDS-related Kaposi's sarcoma, systemic NHL, and primary central nervous system (CNS) lymphoma. RESULTS: Of the 14 183 adults with AIDS, 3028 were diagnosed with Kaposi's sarcoma, 776 with systemic NHL, and 254 with CNS NHL. After adjustment for potential confounders, more recent calendar period and use of HAART were significantly associated with a decreased risk of Kaposi's sarcoma, whereas HAART use but not calendar period was significantly associated with systemic and CNS NHL. In adjusted analysis of Kaposi's sarcoma survival time, there was strong evidence of a reduced risk of death associated with HAART use and more recent calendar period. In contrast, in adjusted analyses of systemic NHL survival time, HAART use was not associated with improved survival time; however, calendar period was associated with longer survival. In adjusted analysis of CNS NHL survival time, only cancer treatment was associated with a longer survival time. CONCLUSION: After controlling for calendar period and other confounders, use of HAART decreased the risk of Kaposi's sarcoma, systemic NHL, and CNS NHL. Use of HAART also increased Kaposi's sarcoma survival time but not NHL survival time.

RESUMEN

Prior evidence suggests that the health and longevity benefits of antiretroviral therapy (ART) for persons living with AIDS (PLWAs) have not been equally distributed across racial/ethnic groups in the United States. Notably, black PLWAs tend to fare worse than their counterparts. We examine the role of neighborhood socioeconomic context on racial/ethnic differences in AIDS treatment and survival in San Francisco. The study population encompassed 4211 San Francisco residents diagnosed with AIDS between 1996 and 2001. Vital status was reported through 2006. Census data were used to define neighborhood-level indicators of income, housing, demographics, employment and education. Cox proportional hazards models were employed in multivariate analyses of survival times. Compared to whites, blacks had a significant 1.4 greater mortality hazard ratio (HR), which decreased after accounting for ART initiation. PLWAs in the lowest socioeconomic neighborhoods had a significant HR of 1.4 relative to those in higher socioeconomic neighborhoods, independent of race/ethnicity. The neighborhood association decreased after accounting for ART initiation. Path analysis was used to explore causal pathways to ART initiation. Racial/ethnic differences in neighborhood residence accounted for 19-22% of the 1.6-1.8 black-white relative odds ratio (ROR) and 14-15% of the 1.3-1.4 Latino-white ROR for delayed or no treatment. Our findings illuminate the independent and synergistic contributions of race and place on treatment disparities and highlight the need for future studies and interventions to address treatment initiation as well as neighborhood effects on treatment differences.

RESUMEN

Highly active antiretroviral therapy (HAART) has dramatically reduced the incidence of acquired immunodeficiency syndrome (AIDS) and increased AIDS survival time, but little is known about its impact on cancer. Data from adults in the San Francisco, California, AIDS surveillance registry were computer matched with the California Cancer Registry. Age-, sex-, and race-adjusted standardized incidence ratios (SIRs) were computed, and proportional hazards models evaluated the effect of HAART use on cancer incidence and cancer survival time. Among 14,210 adults with AIDS diagnosed in 1990-2000, 482 non-AIDS-defining cancers were diagnosed. Compared with rates for the general population, significantly increased cancer incidence rates were observed for anal (SIR = 13.4), Hodgkin's lymphoma (SIR = 11.5), liver (SIR = 3.6), oral cavity and pharynx (SIR = 2.6), respiratory (SIR = 2.6), leukemia (SIR = 2.4), skin melanoma (SIR = 2.4), and prostate (SIR = 1.7) cancers. Risk of liver cancer was lower with HAART use (relative hazard (RH) = 0.32). Risk of anal cancer increased after 1995 (RH = 2.9). Respiratory cancer (RH = 0.40) and Hodgkin's lymphoma (RH = 0.17) showed increased cancer survival time with HAART use, while anal cancer survival may have been slightly decreased (RH = 1.4). The impact of HAART on non-AIDS-defining cancer incidence rates and survival is not uniform, and the mechanism(s) responsible for these differences should be investigated further.

RESUMEN

OBJECTIVE: Depressive symptoms are associated with an increased risk of cardiac events in patients with heart disease. Elevated catecholamine levels may contribute to this association, but whether depressive symptoms are associated with catecholamine levels in patients with heart disease is unknown. METHOD: The authors examined the association between depressive symptoms (defined by a Patient Health Questionnaire score > or =10) and 24-hour urinary norepinephrine, epinephrine, and dopamine excretion levels in 598 subjects with coronary disease. RESULTS: A total of 106 participants (18%) had depressive symptoms. Participants with depressive symptoms had greater mean norepinephrine excretion levels than those without depressive symptoms (65 microg/day versus 59 mug/day, with adjustment for age, sex, body mass index, smoking, urinary creatinine levels, comorbid illnesses, medication use, and cardiac function). In logistic regression analyses, participants with depressive symptoms were more likely than those without depressive symptoms to have norepinephrine excretion levels in the highest quartile and above the normal range. Depressive symptoms were not associated with dopamine or epinephrine excretion levels. CONCLUSIONS: In patients with coronary disease, depressive symptoms are associated with elevated norepinephrine excretion levels. Future longitudinal studies are needed to determine whether elevations in norepinephrine contribute to adverse cardiac outcomes in patients with depressive symptoms.

RESUMEN

BACKGROUND: Depression leads to adverse outcomes in patients with coronary heart disease (CHD). Medication nonadherence is a potential mechanism for the increased risk of CHD events associated with depression, but it is not known whether depression is associated with medication nonadherence in outpatients with stable CHD. METHODS: We examined the association between current major depression (assessed using the Diagnostic Interview Schedule) and self-reported medication adherence in a cross-sectional study of 940 outpatients with stable CHD. RESULTS: A total of 204 participants (22%) had major depression. Twenty-eight (14%) of 204 depressed participants reported not taking their medications as prescribed compared with 40 (5%) of 736 nondepressed participants (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.7-4.7; P<.001). Twice as many depressed participants as nondepressed participants (18% vs 9%) reported forgetting to take their medications (OR, 2.4; 95% CI, 1.6-3.8; P<.001). Nine percent of depressed participants and 4% of nondepressed participants reported deciding to skip their medications (OR, 2.2; 95% CI, 1.2-4.2; P = .01). The relationship between depression and nonadherence persisted after adjustment for potential confounding variables, including age, ethnicity, education, social support, and measures of cardiac disease severity (OR, 2.2; 95% CI, 1.2-3.9; P = .009 for not taking medications as prescribed). CONCLUSIONS: Depression is associated with medication nonadherence in outpatients with CHD. Medication nonadherence may contribute to adverse cardiovascular outcomes in depressed patients.
