Racial Microaggressions Mediate the Association Between Posttraumatic Stress and Alcohol Use Among Women of Color Experiencing Intimate Partner Violence

Objective: Women of Color (WoC) experiencing intimate partner violence (IPV) have elevated rates of posttraumatic stress disorder (PTSD) and alcohol use and related harm (e.g., increased alcohol use and negative consequences). This secondary data analysis assessed the role of racial microaggressions in the association between PTSD and alcohol use and related harm among WoC experiencing IPV. Methods: Participants were 103 WoC currently experiencing IPV and using substances (Mage=40.39, 51.5% Black) who were recruited from the community and completed assessments of PTSD, racial microaggressions, and alcohol use and related harm. Results: Assumptions of Inferiority (e.g., intelligence; B = 1.44, SE = 0.90, 95% CI [0.10, 3.54]) and Environmental Microaggressions (e.g., portrayal in media; B = 1.88, SE = 1.03, 95% CI [0.28, 4.30]) explained the association between PTSD and alcohol use and related harm. Conclusions: Findings underscore the influence of specific microaggressions in the relation between PTSD and alcohol use and related harm among WoC experiencing IPV.

A systematic meta-epidemiologic review on nonabstinence-inclusive interventions for substance use: inclusion of race/ethnicity and sex assigned at birth/gender

Background: Minoritized racial/ethnic and sex assigned at birth/gender groups experience disproportionate substance-related harm. Focusing on reducing substance-related harm without requiring abstinence is a promising approach.Objectives: The purpose of this meta-epidemiologic systematic review was to examine inclusion of racial/ethnic and sex assigned at birth/gender in published studies of nonabstinence-inclusive interventions for substance use.Methods: We systematically searched databases (PubMed and PsycINFO) on May 26, 2022 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Articles were eligible for inclusion if they: 1) reported in English language, 2) had a primary goal of investigating a nonabstinence-inclusive intervention to address substance use, 3) used human subjects, and 4) only included adults aged 18 or older. Two coders screened initial articles and assessed eligibility criteria of full text articles. A third consensus rater reviewed all coding discrepancies. For the remaining full-length articles, an independent rater extracted information relevant to study goalsResults: The search strategy yielded 5,759 records. 235 included articles remained. Only 73 articles (31.1%) fully reported on both racial/ethnic and sex assigned at birth/gender, and only seven articles (3.0%) reported subgroup analyses examining treatment efficacy across minoritized groups. Nine articles (3.8%) mentioned inclusion and diversity regarding both racial/ethnic and sex assigned at birth/gender in their discussion and four articles (1.7%) broadly mentioned a lack of diversity in their limitationsConclusion: Findings highlight that little is known about nonabstinence-inclusive interventions to address substance use for individuals from minoritized racial/ethnic and sex assigned at birth/gender groups.

An investigation of laboratory-based positive and negative emotional suppression in relation to posttraumatic stress disorder symptom clusters

BACKGROUND

Emotional suppression is a clinically significant aspect of emotion regulation with robust associations to psychopathology, including posttraumatic stress disorder (PTSD). Despite the fast-growing body of literature highlighting the role of positive emotion regulation difficulties in the development and maintenance of PTSD, extant work on emotional suppression and PTSD has almost exclusively focused on the role of negative emotions.

OBJECTIVE

The present study aimed to advance this literature by examining the associations between PTSD symptom clusters and participants' use of state emotional suppression during a laboratory task designed to elicit negative or positive emotions.

METHOD

Participants were 108 community women (Mage = 39.55; 33% Black/African American) currently experiencing intimate partner violence (IPV) by a male partner and using substances. Participants were interviewed using a structured diagnostic assessment for PTSD and reported on state emotional intensity and emotional suppression following idiographic negative or positive emotion inductions.

RESULTS

Results of the moderation analyses showed that, when controlling for state emotional intensity, women experiencing clinical levels of PTSD symptom Clusters B (intrusive recollections), D (negative alterations in cognitions and mood), and E (alterations in arousal and reactivity) were significantly more likely to utilize emotional suppression, but only in the context of positive-not negative-emotions.

CONCLUSIONS

Findings provide evidence for a link between PTSD and positive emotional suppression among women currently experiencing IPV by a male partner and using substances, highlighting positive emotional suppression as a potential target in PTSD treatment for IPV populations with comorbid substance use concerns.

Trauma and Substance Use among Indigenous Peoples of the United States and Canada: A Scoping Review

Substance use has been identified by Indigenous populations as contributing to health disparities facing their communities. Rates of trauma exposure and post-traumatic stress disorder are higher in Indigenous, compared to non-Indigenous, populations and have been linked to substance use. Historical trauma is thought to be one mechanism underlying substance use and related disorders. The purpose of the present study is to summarize the current state of the literature focusing on the association between trauma (historical and lived) and substance use among Indigenous populations in the United States and Canada. Databases were systematically searched using the preferred reporting items for systematic reviews and meta-analyses statement. The search strategy initially yielded 4,026 articles. After exclusion of ineligible articles, 63 articles remained for synthesis. Results of the present review provide evidence for a positive link between substance use and both historical trauma (i.e., 86.4% of studies) and lived trauma (i.e., 84.7% of studies). Indigenous participants reported that historical trauma and pain related to loss of cultural identity contributed to substance use in their communities. Indigenous participants also consistently described an association between lived trauma and substance use. Despite heterogeneity among Indigenous communities, findings suggest a significant association between trauma and substance use across many different tribes and settings (e.g., reservation/reserve, rural/urban). Indigenous participants identified healing from trauma and reconnecting with culture as necessary components for reducing substance use and maintaining sobriety. With this, the development and implementation of interventions should partner with Indigenous communities in a manner that promotes and enhances cultural values for healing.

Ground-up approach to understanding the impacts of historical trauma in one reserve-dwelling first nations community

OBJECTIVE

First Nations peoples experience disproportionate health inequities compared to most non-Indigenous populations. Historical trauma is one factor that has received growing attention in relation to health inequities among First Nations populations. The goal of the present study was to improve understanding of the specific forms, impacts, and mechanisms of transmission of events that lead to historical trauma and the historical trauma response in First Nations peoples.

METHOD

Five focus groups were conducted among adult members of one First Nations community in Canada (N = 34; 70.4% female).

RESULTS

Conventional content analysis revealed the numerous forms that historical trauma take in this First Nations community; individual-, familial-, community-, and societal-level impacts of historical trauma; and ways in which historical trauma has been transmitted in this community. Loss of culture, alcohol use, and parenting were major themes identified across these domains.

CONCLUSIONS

Findings provide important information on the experience of historical trauma in one First Nations community, highlighting the roles of loss of culture; alcohol use; and parenting in the forms, impacts, and transmission of historical trauma.

Online crowdsourcing to study trauma and mental health symptoms in military populations: A case for Amazon's Mechanical Turk (MTurk) platform

INTRODUCTION

Amazon's Mechanical Turk (MTurk) appears to be a reliable resource for studying clinical populations and accessing hard-to-reach populations. Recent research suggests that MTurk may also be a viable option for military recruitment.

OBJECTIVE

The goal of the current study was to examine the utility of collecting clinical data on military samples recruited via MTurk.

METHOD

Participants were 535 military veterans (Mage = 37.45; 71.8% men; 69.5% White) who completed measures assessing trauma and mental health.

RESULTS

Findings indicate that rates of military traumas and mental health diagnoses were higher than published comparisons; posttraumatic stress disorder (PTSD) and depression symptoms were found to be higher than values found in a nationally representative sample, lower than a treatment-seeking sample, and comparable to a MTurk-recruited military sample. Alcohol misuse was found to be higher than both nationally representative and treatment-seeking samples. Psychometric analyses indicated support for convergent validity of measures, and confirmatory factor analysis results demonstrated that empirically supported factor models of PTSD were replicated in the current sample; the hybrid model demonstrated the best fit.

CONCLUSIONS

Our findings support the utility of MTurk for collecting clinical data on military samples. Increasing access to and recruitment of military samples is important for advancing the field of military psychology. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Ecological investigation of the co-occurrence of posttraumatic stress disorder symptoms and cannabis use among community women experiencing intimate partner violence

BACKGROUND

Women experiencing intimate partner violence (IPV) are at increased risk for developing hazardous patterns of cannabis use. Research suggests that women experiencing IPV use cannabis to cope with posttraumatic stress disorder (PTSD) symptoms. To advance research, we used experience sampling methods to explicate the within-day concurrent and proximal relations between PTSD symptom clusters and cannabis use among women experiencing IPV.

METHOD

Participants were 145 community women (M age = 40.66, 41.6% white, 31.4% Black, 10.9% Hispanic or Latina, 8% American Indian/Alaska Native, 5.8% Bi-/multi-racial) experiencing IPV and using substances who completed three surveys a day for 30 days.

RESULTS

Externalizing behavior (OR = 1.37, 95% CI [1.15, 1.65], p < 0.001) and dysphoric arousal (OR = 1.27, 95% CI [1.09, 1.49], p = 0.002) PTSD symptom clusters were associated with cannabis use reported in the same survey period. Results from the lagged models found no proximal associations between PTSD symptom clusters and cannabis use.

CONCLUSIONS

Results highlight the acute effects of externalizing behavior and dysphoric arousal PTSD symptoms on cannabis use among women experiencing IPV. These findings may inform prevention and intervention efforts for cannabis use in this population.

Measurement Invariance and Application of an Alcohol-Related Consequence Scale for American Indian Adolescents

American Indian (AI) adolescents experience disproportionate alcohol-related consequences. The present study evaluated the psychometric properties and application of the American Drug and Alcohol Survey (ADAS™) alcohol-related consequence scale for AI adolescents through a secondary analysis of a large population-based sample of adolescents living on or near AI reservations. We found support for the ADAS alcohol-related consequence scale as a one-factor model, invariant discretely across race, sex assigned at birth, and age, and with good internal consistency. Evidence for construct validity was found through significant positive correlations between frequency of past 12 months of drinking, frequency of past 12 months of intoxication, and lifetime alcohol-related consequences. AI adolescents were significantly more likely to report more alcohol-related consequences than their non-Hispanic White peers. Race significantly interacted with frequency of drinking in predicting alcohol-related consequences such that these associations were stronger for AI adolescents. However, race did not significantly interact with frequency of intoxication in predicting alcohol-related consequences. Results from this study demonstrate the utility of the ADAS alcohol-related consequence scale for use across demographic groups with little risk of measurement bias.

Measurement invariance and other psychometric properties of the Short Inventory of Problems (SIP-2R) across racial groups in adults experiencing homelessness and alcohol use disorder

OBJECTIVE

People experiencing homelessness are disproportionately impacted by alcohol-related harm. Racially minoritized groups are disproportionately represented in the homeless population and are likewise disproportionately impacted by alcohol-related harm. Most alcohol outcome measures have not been adequately psychometrically studied in this marginalized population and across racial groups. This study documents psychometric properties, including measurement invariance, reliability, and convergent validity, of a measure of alcohol-related harm, the Short Inventory of Problems (SIP-2R), across Black, North American Indigenous (NAI), and White adults experiencing homelessness and alcohol use disorder (AUD).

METHOD

Adults experiencing homelessness and AUD who had participated in one of two randomized controlled trials of harm-reduction treatment (N = 493; NAI = 205, Black = 125, and White = 163) were included in this psychometric study of the 15-item SIP-2R.

RESULTS

Multigroup confirmatory factor analysis (MGCFA) indicated that a model comprising one general alcohol-related harm factor overarching five factors, showed close fit and partial scalar invariance, χ²(329, N = 493) = 624.902, p < .001, comparative fit index (CFI) = .966, root-mean-square error of approximation (RMSEA) = .074, 90% CI [.066, .083], standardized root-mean-square residual (SRMR) = .063, confirming acceptable measurement equivalence across racial groups. The SIP-2R showed internal consistency (α = .94, ω = .95) and convergent validity, that is, positive correlation between the total SIP-2R score and the number of drinks consumed the heaviest drinking day, ρ(490) = .30, p < .001.

CONCLUSION

This study provided support for the internal consistency, convergent validity, and cross-group measurement equivalence of the SIP-2R for NAI, Black, and White adults experiencing homelessness with AUD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Posttraumatic stress as a moderator of the association between HPA-axis functioning and alcohol use disorder among a community sample of women currently experiencing intimate partner violence

Women experiencing intimate partner violence (IPV) experience a heightened prevalence of alcohol use disorder (AUD). Hypothalamic-pituitary-adrenal (HPA)-axis functioning has been associated with increased risk for AUD in other populations, including individuals with posttraumatic stress disorder (PTSD) symptoms. The goal of the present study was to determine whether PTSD symptom severity exacerbates the relationship between HPA-axis functioning and AUD. Participants were 151 community women who had experienced physical or sexual IPV in the past 30 days by their current male partners and used any amount of alcohol or drugs. A two-phase emotion induction protocol was utilized: Neutral mood induction followed by randomly assigned negative, positive, or neutral emotion induction. Saliva cortisol samples were obtained immediately following the neutral mood induction (baseline HPA-axis functioning), 20 min following the individualized emotion induction script (HPA-axis reactivity), and 40 min post the emotionally evocative cue (HPA-axis recovery). Findings revealed that PTSD symptom severity moderated the relations between baseline HPA-axis functioning and HPA-axis recovery and log odds of meeting criteria for AUD. Specifically, baseline HPA-axis functioning was positively associated with log odds of meeting criteria for AUD at high (but not low) PTSD symptom severity, whereas HPA-axis recovery was negatively associated with log odds of meeting criteria for AUD at high (but not low) PTSD symptom severity. Results contribute to our understanding of the biological processes involved in the etiology and maintenance of AUD among women experiencing IPV-specifically the prominent role of PTSD symptom severity.

Cultural identity affiliation and alcohol use and related consequences among American Indian and White adolescents: A latent profile analysis

BACKGROUND

Adolescent alcohol use is a significant public health concern and rates of alcohol use are higher among American Indian (AI) adolescents than national samples of non-AI youth. A potential factor in understanding AI alcohol use is cultural identity, which can vary widely based on experiences of historical trauma. We used latent class analysis to examine cultural identity in AI and White adolescents and their alcohol use outcomes in relation to the latent class solutions.

METHODS

The samples included 3189 AI adolescents (M_age  = 14.76, 48.9% female) and 1579 White adolescents (M_age  = 15.56, 48.7% female) living on or near a reservation. Participants completed self-report measures of AI and White cultural identity affiliation, alcohol use, and alcohol-related problems. We examined (1) the best-fitting latent class solution with respect to American Indian (AI) and White cultural identity; (2) equivalence of the latent class solution; and (3) alcohol use outcomes across the optimal latent class solution.

RESULTS

Latent profile analyses indicated an optimal 3-class solution in both the AI and White samples, which differed by level of affiliation with AI and White cultural identity. While the optimal number of classes were similar across racial groups (configural profile similarity), the nature of the classes differed (structural profile dissimilarity). The three classes represented low overall scores on AI and White cultural identity (Marginalized), a mixture of high and low scores on AI and White cultural identity (Third Culture), and overall high scores on AI and White cultural identity (Bicultural). Alcohol-related problems predicted membership in the Third Culture class compared with the Marginalized class and the Bicultural class. Specifically, youth in the Third Culture class reported significantly fewer alcohol-related problems than youth in the Marginalized and Bicultural classes. Alcohol use did not predict latent class membership.

CONCLUSIONS

The future-oriented nature of the Third Culture class may provide protection against adverse alcohol-related outcomes. Research is needed to test interventions that target greater future orientation and future plans to integrate culture into adolescents' lives.

Harm reduction acceptability and feasibility in a North American indigenous reserve community

AIMS

The present study assessed community and culturally specific alcohol-related harm among North American Indigenous (NAI) individuals, as well as the acceptability and feasibility of harm reduction approaches in one reserve-based NAI community.

METHODS

Participants lived on or near a NAI reserve in Canada. Semi-structured focus groups were conducted with health care workers (N = 8, 75% NAI) and community members (N = 9, 100% NAI). Self-report questionnaires were administered that measured acceptability and feasibility of harm reduction strategies.

RESULTS

Conventional content analysis revealed loss of culture as culturally specific alcohol-related harm. Health care workers rated harm reduction approaches to be acceptable and feasible, while community participants were more mixed. Majority of participants felt that some harm reduction strategies could provide opportunities for individuals who use alcohol to connect to Indigenous culture and traditions. However, there were mixed findings on whether harm reduction strategies are consistent with Indigenous cultural traditions and values.

CONCLUSION

Future research is needed to evaluate potential utility of harm-reduction approaches for NAI communities.

Modeling reciprocal relations between emotion dysregulation and alcohol use using dynamic structural equation modeling: A micro-longitudinal study

BACKGROUND

Research examining emotion dysregulation and alcohol use has increased exponentially over the past decade. However, these studies have been limited by their use of cross-sectional designs and narrow definitions of emotion dysregulation. To address these significant gaps in the extant literature, this study utilized state-of-the-art methodology (i.e., experience sampling) and statistics (i.e., dynamic structural equation modeling) to examine potential reciprocal associations between negative and positive emotion dysregulation and alcohol use at the momentary level.

METHODS

Participants were 145 community women (mean age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances. Surveys assessing negative and positive emotion dysregulation and alcohol use (i.e., number of standard drinks) were administered three times a day for 30 days using phone-based interactive voice recording.

RESULTS

Significant contemporaneous effects indicated that negative and positive emotion dysregulation both co-occurred with alcohol use. However, levels of negative and positive emotion dysregulation did not predict later alcohol use, nor did alcohol use predict later levels of negative or positive emotion dysregulation. There was significant variability among participants in cross-lagged effects.

CONCLUSIONS

Findings showed that negative and positive emotion dysregulation co-occurred with alcohol use and that there was significant interindividual variability in the cross-lagged associations between negative and positive emotion dysregulation and alcohol use. Research using idiographic approaches may identify women experiencing IPV for whom negative and positive emotion dysregulation drive alcohol use and alcohol use drives negative and positive emotion dysregulation.

Assaultive trauma, alcohol use, and alcohol-related consequences among American Indian adolescents

BACKGROUND

American Indian (AI) adolescents report disproportionate higher rates of alcohol use and alcohol-related consequences than adolescents from other racial/ethnic groups. Trauma exposure is also reported at high rates among AI individuals and likely confers risk for alcohol use. The purpose of the present study was to examine the effects of assaultive trauma experiences (e.g., physical assault, sexual assault) on alcohol use and alcohol-related consequences in AI adolescents.

METHODS

We conducted a secondary analysis of self-reported data on trauma exposure, alcohol consumption, and lifetime alcohol-related consequences provided by AI 7th to 12th graders residing on or near a reservation (n = 3498, M_age  = 14.8; 49.5% female). Institutional Review Boards, tribal authorities, and school boards approved the study protocols prior to beginning data collection.

RESULTS

Nearly half (49.3%, n = 1498) of AI adolescents reported having experienced at least one assaultive trauma in their lifetime. Those who had experienced assaultive trauma were more likely to report lifetime alcohol use (χ²  = 111.84, p < 0.001) and experienced greater alcohol-related consequences (t(1746) = 12.21, p < 0.001) than those with no assaultive trauma exposure. Multilevel regression analyses indicated that a greater number of assaultive traumatic events was significantly associated with greater odds of lifetime alcohol use (p < 0.001, OR = 1.81, 95% CI [1.65, 2.00]) and having experienced a greater number of alcohol-related consequences (b = 0.36, SE = 0.04, t = 16.95, p < 0.001, 95% CI [0.31, 0.46]).

CONCLUSIONS

Findings of the present study highlight the relevance of exposure to assaultive trauma to AI adolescents' use of alcohol and experiences of alcohol-related consequences. These findings support the need for trauma-informed interventions in addressing alcohol use among AI adolescents.

Posttraumatic Stress Disorder and Substance Misuse Among Black Emerging Adults: The Influence of Social Support

Objective: Black emerging adults are significantly impacted by substance misuse. Posttraumatic stress disorder (PTSD) is associated with heightened substance misuse among Black emerging adults. However, limited research has identified protective factors that may influence the strength of the relation between PTSD and substance misuse in this population. Addressing this important limitation, the present study examined the potential moderating role of perceived social support in the association between PTSD symptoms and substance (i.e., alcohol and drug) misuse. Methods: Participants were 182 trauma-exposed Black emerging adults (M age = 20.50; 71.3% women) who completed self-report measures assessing PTSD symptoms, alcohol and drug misuse, and perceived social support. Results: PTSD symptoms were significantly and positively correlated with both alcohol and drug misuse. Moderation analyses indicated that positive relations between PTSD symptoms and both alcohol and drug misuse were only significant among Black emerging adults with lower (but not higher) levels of perceived social support. Conclusions: These findings suggest the potential utility of addressing social support in the assessment and treatment of substance misuse in trauma-exposed Black emerging adults.

A Framework for the Adaptation of Positive Psychological Interventions to North American Indigenous Populations

Positive psychology research has led to the development of brief interventions designed to promote positive emotions: positive psychological interventions (PPIs). Randomized controlled trials examining PPIs have found them to be effective in increasing well-being and decreasing depressive symptoms. PPIs have been studied in samples consisting primarily of White Americans; however, PPIs may be useful for members of North American Indigenous groups. PPIs align well with Indigenous views on health, which tend to be strengths-based, holistic, and encompassing the whole body (including the medicine wheel's four dimensions of spirit, mind, heart, and body). This paper provides a framework for the adaptation of PPIs for Indigenous communities and a review of preliminary data on the relationships between positive psychological characteristics and health outcomes including substance use. Implications include the potential widespread impact of culturally adapted PPIs given their alignment with Indigenous thoughts on health and relative ease of administration.

Characterizing components of and attendance at resident-driven Housing First programming in the context of community-based participatory research

AIMS

This secondary study characterized components of and engagement in the life-enhancing alcohol-management program (LEAP), which is resident-driven housing first programming.

METHODS

We used a process akin to conventional content analysis to operationalize the LEAP according to its component activities. We used generalized linear modeling to identify predictors of LEAP activity participation and to predict alcohol and quality-of-life outcomes from participation in specific LEAP activities categories.

RESULTS

Overall, 86% of participants attended at least one LEAP activity, which comprised three categories: administrative leadership opportunities, meaningful activities, and pathways to recovery. Employment status alone predicted LEAP activity attendance: Employed residents attended 88% fewer LEAP activities than unemployed residents. Participants who sought out more pathways to recovery activities were more likely daily drinkers and more impacted by alcohol-related harm. Those engaging in administrative leadership opportunities were overall less impacted by alcohol use and had a higher quality of life generally, and their alcohol outcomes further improved over time.

CONCLUSIONS

Programming developed with Housing First residents was well-attended but could be made more inclusive by including evening programming to accommodate residents employed full time and engaging more severely impacted participants in administrative leadership activities, where the greatest benefits of programming were seen.

The protective effects of self-compassion on alcohol-related problems among First Nation adolescents

Given the disproportionate alcohol-related consequences experienced by North American Indigenous youth, there is a critical need to identify related risk and protective factors. Self-compassion, which has been found to mitigate the effects of trauma exposure, may serve as one such protective factor given the high-degree of historical trauma and contemporary discrimination identified as contributing to the alcohol-related disparities experienced by Indigenous communities. However, no research has examined how self-compassion (i.e., the ability to be kind and accepting and to extend compassion towards oneself) plays a unique role in Indigenous peoples' experiences with alcohol. First Nation adolescents between the ages of 11 and 18 living on a reserve in Eastern Canada (N=106, M _age =14.6, 50.0% female) completed a pencil-and-paper survey regarding their alcohol use, alcohol-related problems, and self-compassion. Self-compassion was significantly inversely associated with alcohol-related problems (b=-.51, p=.01, 95%CI [-.90, -.12], and significantly interacted with frequency of alcohol use in predicting alcohol-related problems (b=-.42, p=.04, 95%CI [-.82, -.03]). Simple slopes analyses revealed that the association between frequency of alcohol use and frequency of experiencing alcohol-related problems was significant and positive at low (b=4.68, p<.001, 95%CI [2.62, 6.73]), but was not significant at high (b=-.29, p=.89, 95%CI [-4.35, 3.77]) levels of self-compassion. Binary logistic regression revealed that higher scores of self-compassion were associated with a lower odds of being in the high-risk group for AUD (OR=0.90, 95%CI [0.83, 0.98], p=.02). Our results suggest self-compassion may be protective against experiencing alcohol problems in Indigenous youth and thus may be a target for behavioral interventions.

Jail and Emergency Department Utilization in the Context of Harm Reduction Treatment for People Experiencing Homelessness and Alcohol Use Disorder

People experiencing homelessness are disproportionately affected by alcohol use disorder (AUD). Abstinence-based treatment, however, does not optimally engage or treat this population. Thus, Harm Reduction Treatment for Alcohol (HaRT-A) was developed together with people with the lived experience of homelessness and AUD and community-based agencies that serve them. HaRT-A is a compassionate and pragmatic approach that aims to help people reduce alcohol-related harm and improve quality of life (QoL) without requiring abstinence or use reduction. The parent RCT showed that HaRT-A precipitated statistically significant reductions in alcohol use, alcohol-related harm, AUD symptoms, and positive urine toxicology tests. This secondary study tested HaRT-A effects on more distal, 6-month pre-to-posttreatment changes on jail and emergency department (ED) utilization. People experiencing homelessness and AUD (N = 168; 24% women) were recruited in community-based clinical and social services settings. Participants were randomized to receive HaRT-A or services as usual. Over four sessions, HaRT-A interventionists delivered three components: (a) collaborative tracking of participant-preferred alcohol metrics, (b) elicitation of harm-reduction and QoL goals, and (c) discussion of safer-drinking strategies. Administrative data on jail and ED utilization were extracted for 6 months pre- and posttreatment. Findings indicated no statistically significant treatment group differences on 6-month changes in jail or ED utilization (ps > .23). Exploratory analyses showed that 2-week frequency of alcohol use was positively correlated with number of jail bookings in the 12 months surrounding their study participation. Additionally, self-reported alcohol-related harm, importance of reducing alcohol-related harm, and perceived physical functioning predicted more ED visits. Future studies are needed to further assess how harm-reduction treatment may be enhanced to move the needle in criminal justice and healthcare utilization in the context of larger samples, longer follow-up timeframes, and more intensive interventions.

Valuing Cultural Activities Moderating the Association Between Alcohol Expectancies and Alcohol Use Among First Nation Adolescents

OBJECTIVE

Indigenous youth often exhibit high rates of alcohol use and experience disproportionate alcohol-related harm. We examined the moderating role that valuing cultural activities has on the relationship between positive alcohol expectancies and alcohol use and heavy drinking in a sample of Indigenous youth.

METHOD

First Nation adolescents between ages 11 and 18 living on a reserve in eastern Canada (N = 106; mean age = 14.6; 50.0% female) completed a pencil-and-paper survey regarding their positive alcohol expectancies, alcohol use, and beliefs about the importance of cultural activities.

RESULTS

A significant interaction was identified between positive alcohol expectancies and valuing cultural activities on past-3-month alcohol use (b = -0.01, SE = 0.001, p < .001) and past-3-month heavy drinking (b = -0.01, SE = 0.001, p < .001). Simple slopes analysis revealed that the association between positive alcohol expectancies and past-3-month alcohol use and heavy drinking was significant for those with low (b = 0.06, SE = 0.007, p < .001; b = 0.07, SE = 0.008, p < .001; respectively) but not high levels of valuing cultural activities (b = 0.01, SE = 0.008, p = .12; b = 0.01, SE = 0.009, p = .08; respectively).

CONCLUSIONS

Highly valuing cultural activities may interrupt the relationship between positive alcohol expectancies and alcohol use. This suggests that community interventions and treatment programs targeting alcohol use among Indigenous adolescents should prioritize increasing the value of cultural activities by perhaps making them more available.

Testing the competing life reinforcers model for substance use in reserve-dwelling First Nation youth

PURPOSE

North American Indigenous (NAI) communities often cite substance misuse as problematic in their communities. The Competing Life Reinforcers (CLRs) model suggests that when reinforcers are valued, important, and incompatible with substance use, they will be associated with less substance misuse. Three categories of CLRs were identified in our formative work and include the following: cultural, social, and extracurricular activities. The aims of the current study were to test the associations among valuing and availability of CLRs and NAI adolescent alcohol and marijuana use.

METHODS

Adolescents living in rural First Nation reserve communities (N = 106, 50.0% female) reported their substance use and perceived availability and valuing of CLRs (e.g., smudging and after school activities).

FINDINGS

Greater value placed on cultural reinforcers was significantly associated with reduced likelihood of past 3-month drinking to get drunk (OR = 0.85, 95% CI[0.73, 0.98]). Greater value placed on social reinforcers was associated with lower likelihood of past 3-month drinking (OR = 0.94, 95% CI[0.89, 0.995]) and past-3 month drinking to get drunk (OR = 0.94, 95% CI[0.88, 0.99]). Greater valuing extracurricular activities were associated with lower likelihood of past month marijuana use (OR = 0.84, 95% CI[0.72, 098]), past 3-month drinking (OR = 0.77, 95% CI[0.64, 0.92]), and past 3-month drinking to get drunk (OR = 0.76, 95% CI[0.63, 0.92]).

CONCLUSIONS

Identifying Competing Life Reinforcers for Substance Use in First Nation Adolescents

Background: Indigenous youth are at increased risk of initiating substance use at early ages and suffer greater negative consequences related to substance use as compared to non-Indigenous youth. Behavioral Theories of Choice suggests that substance use is contingent on the availability of substances and the availability of alternatives to substance use. Objectives: The present study aimed to investigate risk and protective factors associated with substance use in one group of First Nation adolescents. Methods: Using a modified grounded theory approach, the present study conducted qualitative focus groups and individual interviews with fifteen reserve-dwelling (75% female, M age = 15.2 years) First Nation adolescents to assess categories of risk and protective factors based upon Behavioral Theories of Choice. Results: Adolescents identified peer influences, parental/family influences, and community influences and issues as risk and protective factors associated with substance use. Conclusions: Results highlight possible targets of culturally appropriate prevention strategies for Indigenous populations.

Randomized controlled trial of harm reduction treatment for alcohol (HaRT-A) for people experiencing homelessness and alcohol use disorder

BACKGROUND

People experiencing homelessness are disproportionately affected by alcohol use disorder (AUD). Abstinence-based treatment, however, does not optimally engage or treat this population. Thus, harm reduction treatment for alcohol (HaRT-A) was developed together with people with lived experience of homelessness and AUD and community-based agencies that serve them. HaRT-A is a compassionate and pragmatic approach that aims to help people reduce alcohol-related harm and improve quality of life (QoL) without requiring abstinence or use reduction. A three-month, two-arm randomized controlled trial was conducted to test the initial efficacy of HaRT-A compared to a services-as-usual control condition.

METHODS

People experiencing homelessness and AUD (N = 168; 24% women) were recruited in community-based clinical and social services settings. Self-reported alcohol use, alcohol-related harm, motivation, and QoL as well as urinary ethyl glucuronide were assessed over a 3-month follow-up. Participants were randomized to receive HaRT-A or services as usual. Over four sessions, HaRT-A interventionists delivered three components: a) collaborative tracking of participant-preferred alcohol metrics, b) elicitation of harm-reduction and QoL goals, and c) discussion of safer-drinking strategies.

RESULTS

Compared to control participants, HaRT-A participants reported significantly greater increases in confidence to engage in harm reduction and decreases in peak alcohol use, alcohol-related harm, AUD symptoms, and positive urinary ethyl glucuronide tests (ps < .05). Findings were inconclusive regarding group differences on QoL (ps > .12).

CONCLUSION

A low-barrier, low-intensity, patient-driven, harm-reduction approach has at least short-term efficacy in improving AUD outcomes in this population. Future studies are needed to establish its longer-term efficacy.

Harm reduction treatment for smoking (HaRT-S): findings from a single-arm pilot study with smokers experiencing chronic homelessness

Background: Smoking prevalence and mortality is 5 times higher for the chronically homeless versus general population. Unfortunately, traditional smoking cessation treatment does not optimally engage this population. In a preliminary study, smokers experiencing chronic homelessness suggested providers avoid giving advice to quit and instead use a more compassionate, nonjudgmental style to discuss a broader menu of patient-driven options, including safer nicotine use. Most had negative perceptions of smoking cessation medications; however, 76% expressed interest in a switchover to electronic nicotine delivery systems (ENDS). Methods: Using a community-based participatory research approach, we codeveloped harm-reduction treatment for smoking (HaRT-S) together with people with lived experience of chronic homelessness and smoking and a community-based agency that serves them. In HaRT-S, interventionists embody a compassionate, advocacy-oriented "heart-set" and deliver manualized components: a) participant-led tracking of smoking-related outcomes, b) elicitation of harm-reduction goals and progress made toward them, c) discussion of relative risks of nicotine delivery systems, and d) distribution and instructions on use of safer nicotine products. We then conducted a single-arm, 14-week pilot of HaRT-S (N = 44). Results: Participants rated procedures "totally acceptable/effective," which was reflected in 26% overrecruitment within a 4-month period and 70% retention at the 14-week follow-up. For each week in the study, participants experienced an 18% increase in odds of reporting 7-day, biochemically verified, point-prevalence abstinence. All participants reporting abstinence used ENDS. Participants evinced reductions in cigarette dependence (-45%), frequency (-29%), and intensity (-78%; ps < .05). Participants who used ENDS experienced an additional 44% reduction in smoking intensity and a 1.2-point reduction in dependence compared to participants who did not. Conclusions: Harm-reduction counseling plus ENDS shows promise for smokers experiencing chronic homelessness. Randomized controlled trials are needed to establish the efficacy of this approach in decreasing smoking-related harm and improving health-related quality of life for this marginalized and disproportionately affected population.

B-cell activating factor (BAFF) plasma level at the time of chronic GvHD diagnosis is a potential predictor of non-relapse mortality

Biological markers for risk stratification of chronic GvHD (cGvHD) could improve the care of patients undergoing allogeneic hematopoietic stem cell transplantation. Increased plasma levels of B-cell activating factor (BAFF), chemokine (C-X-C motif) ligand 9 (CXCL9) and elafin have been associated with the diagnosis, but not with outcome in patients with cGvHD. We evaluated the association between levels of these soluble proteins, measured by ELISA at the time of cGvHD diagnosis and before the initiation of therapy, with non-relapse-mortality (NRM). Based on the log-transformed values, factor levels were divided into tertiles defined respectively as low, intermediate, and high levels. On univariable analysis, BAFF levels were significantly associated with NRM, whereas CXCL9 and elafin levels were not. Both low (⩽2.3 ng/mL, hazard ratio (HR)=5.8, P=0.03) and high (>5.7 ng/mL, HR=5.4, P=0.03) BAFF levels were associated with a significantly higher NRM compared with intermediate BAFF level. The significant effect of high or low BAFF levels persisted in multivariable analysis. A subset of cGvHD patients had persistently low BAFF levels. In conclusion, our data show that BAFF levels at the time of cGvHD diagnosis are associated with NRM, and also are potentially useful for risk stratification. These results warrant confirmation in larger studies.

Suicidality Among Chronically Homeless People with Alcohol Problems Attenuates Following Exposure to Housing First

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low-barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2-year follow-up. Baseline suicidal ideation was over four times higher than in the general population. Two-year, within-subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow-up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2-year follow-up.

High-dose corticosteroids with or without etanercept for the treatment of idiopathic pneumonia syndrome after allo-SCT

Idiopathic Pneumonia Syndrome (IPS) is a common complication after allo-SCT and results in high mortality rates. Conventional treatment for IPS typically includes supportive care and high-dose corticosteroids (CS). Data suggests that TNF-α is important in the pathogenesis of IPS and that the TNF-α inhibitor etanercept may be useful for IPS treatment. We performed a retrospective comparison of consecutive patients treated at our center for IPS with CS only from 1999 to 2003 (group 1, n=22) or CS plus etanercept from 2004 to 2007 (group 2, n=17). In all, 18% of patients in group 1 vs 53% in group 2 were successfully taken off respiratory support and discharged from the hospital (P=0.039). OS was significantly better for recipients of CS plus etanercept (P=0.003). The estimated survival at 28 days and 2 years after IPS was 36.4% (95% CI 17-56%) and 9.1% (95% CI 2-25%) for group 1 and 88.2% (95% CI 61-97%) and 18% (95% CI 4-38%) for group 2, respectively. Our retrospective comparison suggests that the addition of etanercept to CS for IPS improves response rates and OS. However, outcomes remain limited in both groups, highlighting the need for more effective interventions to treat early and late complications of IPS.

Has allogeneic stem cell cryopreservation been given the 'cold shoulder'? An analysis of the pros and cons of using frozen versus fresh stem cell products in allogeneic stem cell transplantation

Donor stem cells for allogeneic transplant traditionally are collected and transfused 'fresh' into the recipient on the day of transplant; alternatively such cells can be collected in advance and cryopreserved until needed. Most centers favor the former approach based on theoretical concerns that cryopreservation and thawing may worsen clinical outcomes. Limited published data from single institution retrospective studies show no significant impairment of engraftment or reduced day 100 survival for cryopreserved bone marrow recipients. There are no reported outcomes for recipients of cryopreserved peripheral blood allografts. Use of cryopreserved stem cells is associated with a higher incidence of adverse events (transfusion reactions, bacterial graft contamination and collection of grafts which are not utilized). Conversely, use of cryopreserved grafts introduces a greater flexibility into a stressed healthcare system and results in a more streamlined experience for the donor. Some data suggest that transplantation with a cryopreserved product may lower the incidence of acute graft-versus-host disease. We compare the pros and cons of using 'fresh' versus cryopreserved stem cell products for allogeneic transplantation and suggest that the current standard of using 'fresh' products may not be warranted. We also suggest future areas of exploration to better elucidate this issue.

Long-term event-free survivors after high-dose therapy and autologous stem-cell transplantation for low-grade follicular lymphoma

Although follicular lymphoma (FL) is generally responsive to conventional-dose chemotherapy, improved survival in patients with this disease has been difficult to demonstrate. High-dose chemo/radiotherapy followed by autologous stem-cell transplantation (ASCT) can improve response rates, although its effects on survival remain controversial. Between 1990 and 2003, we transplanted 49 patients with low-grade FL at our institution. Twenty-two patients (45%) had undergone histologic transformation at the time of ASCT. In all, 44 patients (90%) had relapsed disease and five patients (10%) were resistant to chemotherapy at the time of transplantation. After ASCT, 30 patients (61%) were in complete remission (CR). The median overall survival (OS) has not been reached, while the median event-free survival (EFS) is 2.4 years. At a median follow-up of 5.5 years (longest 12.4 years), a plateau has been reached with 56% of patients remaining alive, and 35% event-free. ASCT was well tolerated except for two (4%) treatment-related deaths. In multivariable analysis, CR after ASCT and age less than 60 years are the best predictors of EFS and OS. ASCT is thus a safe therapeutic approach in FL, resulting in long-term EFS and OS for some patients, even with transformed disease.

Intensive graft-versus-host disease prophylaxis is required after unrelated-donor nonmyeloablative stem cell transplantation

Nonmyeloablative stem cell transplantation (NST) harnesses the graft-versus-tumor effect while minimizing regimen-related toxicity, and can result in donor chimerism and remission. Acute graft-versus-host disease (GVHD) and infections are major complications after sibling NST. Toxicity of unrelated-donor (UD) NST and the most appropriate GVHD prophylaxis in this setting remain poorly defined. We describe 25 patients who received UD-NST conditioned with fludarabine and cyclophosphamide. The first six patients received cyclosporine (Cs) and mycophenolate mofetil (MMF) (n=5) or methotrexate (MTX) (n=1) as GVHD prophylaxis (group 1) and all developed grade III-IV acute GVHD. The next 19 patients received the same conditioning regimen with the addition of alemtuzumab, and all received Cs/MTX post-transplant. Engraftment and donor chimerism were achieved in all but one evaluable patient. In all, 15 patients died: five of six deaths in group 1 were attributable to acute GVHD, while deaths in group 2 were due to infection or progressive disease (P=0.05). The combination of Cs/MMF is inadequate GVHD prophylaxis for UD-NST. The use of Cs, MTX, and alemtuzumab eliminated severe acute GVHD; its impact on response merits further study.

Defining the role of novel high-dose chemotherapy regimens for the treatment of high-risk breast cancer

We have explored several novel high-dose combinations in an attempt to increase antitumor activity while decreasing treatment-related toxicity. From October 1989 through June 1997, we performed phase I/II dose-escalation trials exploring novel high-dose regimens including ifosfamide/carboplatin/etoposide, mitoxantrone/thiotepa, and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/mitoxantrone/thiotepa. We have also evaluated busulfan/cyclophosphamide and cyclophosphamide/thiotepa/carboplatin in phase II trials. Three hundred ninety-three patients have been treated in these trials and followed for a minimum of 3 months. Event-free survival (including relapses and treatment-related mortality; +/-SE) at 3 years by stage and chemosensitivity is as follows: stage II, four to nine positive nodes (n=16), 52%+/-17%; stage II, greater than nine nodes (n=30), 46%+/-11%; stage III (n=59), 50%+/-8%; inflammatory stage III (n=15), 27%+/-17%; stage IV, anthracycline responsive (n=69), 19%+/-5%; stage IV, anthracycline refractory but responsive to salvage therapy with ifosfamide, carboplatin, and etoposide or paclitaxel (n=53), 12%+/-6%; stage IV, refractory (n=128), 5%+/-2%; and stage IV, not evaluable for response (n=23), 10%+/-8%. Treatment-related mortality was 4% for both phase I and II studies involving stage II breast cancer patients, 5% for stage III breast cancer, 15% for inflammatory breast cancer, and 18% for all stage IV breast cancers, responsive and refractory. We conclude that high-dose therapy for the treatment of high-risk early stage breast cancer or metastatic breast cancer results in durable remissions. Chemosensitivity to induction regimens remains the most important prognostic indicator, although long-term survival has been seen even in patients with highly refractory disease. Further studies are necessary to define optimal high-dose strategies based on stage and chemosensitivity of disease.

Nephrotoxicity of high-dose ifosfamide/carboplatin/etoposide in adults undergoing autologous stem cell transplantation

The objective of this study was to evaluate nephrotoxicity in adult patients treated with high-dose ifosfamide, carboplatin, and etoposide followed by autologous stem cell transplantation. We conducted a retrospective analysis of clinical and laboratory data from 131 patients with various malignancies who received treatment with escalating doses of ifosfamide, carboplatin, and etoposide followed by autologous stem cell transplantation as part of a phase I/II therapeutic trial. Abnormalities in glomerular filtration were evaluated by measuring peak creatinine levels and tubular dysfunction by the lowest recorded serum levels of potassium, magnesium, and bicarbonate, at different time periods after administration of ifosfamide, carboplatin, and etoposide, and after autologous stem cell transplantation. For the entire group of 131 patients, peak creatinine levels were > 1.5 mg/dL but < 3.0 mg/dL in 37% and levels were > 3.0 mg/dL in 11% at some time during their hospital stay. At the time of discharge, creatinine levels were 1.6 mg/dL to 3.0 mg/dL in 25% of patients and were > 3 mg/dL in 5%. Immediately after high-dose therapy, peak creatinine levels were significantly higher in patients receiving higher doses of ifosfamide compared to those receiving lower doses (P < 0.00001) and those receiving intermediate doses (P < 0.005). There was a dramatic decrease in serum bicarbonate, potassium, and magnesium levels immediately after chemotherapy, and they remained significantly decreased throughout the patient's hospital stay, despite massive replacement efforts (P ranging between < 0.008 and < 0.001). This is the largest adult population study documenting the incidence and severity of ifosfamide/carboplatin/etoposide-associated acute nephrotoxicity. Renal dysfunction was dose related and reversible in the majority of patients.

High-dose chemotherapy and autologous peripheral blood stem cell transplantation in patients with multiple myeloma and renal insufficiency

Six patients with multiple myeloma and chronic renal insufficiency (serum creatinine >3.0 mg/dl), including four on dialysis, received high-dose busulfan and cyclophosphamide (BUCY) followed by autologous peripheral stem cell transplantation. Peripheral blood stem cells were collected after priming with cyclophosphamide, etoposide and G-CSF. Patterns of engraftment and toxicities were not apparently different from those seen in myeloma patients with normal renal function. There was one toxicity-related death, resulting from a massive spontaneous subdural hematoma. One patient died of disease progression 6 months after transplant, while the remaining four patients are alive and free of myeloma progression 6 to 39 months after high-dose therapy. Two of these patients have remained in complete remission for 28 and 39 months. Our experience suggests that high-dose therapy with BUCY and autologous peripheral blood stem cell rescue is feasible in patients with multiple myeloma and renal failure.

Dexamethasone, cyclophosphamide, idarubicin and etoposide (DC-IE): a novel, intensive induction chemotherapy regimen for patients with high-risk multiple myeloma

We evaluated toxicities and responses to a novel, dose intensive and time sequenced, chemotherapy programme (DC-IE) in 45 patients with high-risk myeloma. DC-IE consisted of: dexamethasone (days 1-4); cyclophosphamide (day 5); idarubicin and etoposide (days 8-10). Complete response (CR) was achieved in four patients, six patients achieved near complete responses (nCR) and 21 patients achieved a partial remission (PR). Overall response rate was 76% (CI 56-94%) for newly diagnosed patients (n = 21) and 62% (CI 36-81%) for relapsed/refractory patients (n = 24). Toxicities were limited to myelosuppression; two patients died of sepsis during neutropenia (4%). DC-IE is active and tolerable for high-risk multiple myeloma, including patients with relapsed or refractory disease to anthracycline containing regimens.

Phase I-II study of high-dose busulfan and cyclophosphamide followed by autologous peripheral blood stem cell transplantation for hematological malignancies: toxicities and hematopoietic recovery

In a phase I-II study, we evaluated toxicities, tolerability, pace of engraftment, and tumor responses to high-dose bulsulfan and cyclophosphamide followed by autologous peripheral blood stem cell transplantation in patients with hematological malignancies. We treated 51 patients with various hematological malignancies involving the bone marrow with busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) followed by reinfusion of autologous peripheral blood stem cells. Stem cells were previously collected during hematopoietic recovery after cyclophosphamide (100 mg/kg) and etoposide (600 mg/m2) followed by G-CSF (5 micrograms/kg/day). Neutrophil recovery (>0.5 x 10(9)/I) was rapid in the majority of patients (median 10 days after transplant, range 7-91 days), resulting in a low number of days with severe neutropenia (median 7 days, range 5-85 days) and with fever (median 5 days, range 1-13 days). Platelet recovery, however, was delayed in 60% of patients. There was one acute transplant-related death (2%). Four patients died of late, presumed infections, pulmonary complications (interstitial pneumonia). Tumor responses were documented in a significant proportion of these patients with high-risk hematological malignancies. We conclude that peripheral blood stem cell transplantation results in rapid recovery of neutrophils but variable recovery of platelets after high-dose busulfan and cyclophosphamide, when stem cells are harvested following priming with cyclophosphamide/etoposide and G-CSF. The regimen is well-tolerated with limited non-hematological toxicities and transplant-related mortality. While significant tumor responses were documented in this trial, the ultimate efficacy of the regimen needs to be further defined.

Human cytomegalovirus (HCMV) enhances bovine papilloma virus (BPV) transformation in vitro

Infection of NIH 3T3 cells with a combination of HCMV and BPV resulted in more foci than infection with BPV alone. Foci were microscopically apparent at 4 days in the mixed infection and did not appear until 2 days later in the cultures infected with BPV alone. The enhancement was abolished by heat inactivation of the HCMV and also when the HCMV was replaced by a "mock inoculum." Southern blot analysis of cellular DNA from transformed cells showed a similar amount of extrachromosomal BPV DNA in cells infected by BPV alone and in cells co-infected with HCMV. No HCMV antigens could be found in these cells by immunofluorescence. The mechanisms of the enhancement are not known. Stimulation of host DNA synthesis by HCMV could possibly increase the transforming efficiency of BPV. Alternatively, the increase in BPV transforming efficiency could be due to a transient increase in BPV-1 transcription by an HCMV transcriptional transactivation factor. Since both HCMV and human papillomaviruses are commonly found in the uterine cervix, HCMV may play a role in human cervical cancer by enhancing the carcinogenic potential of human papillomavirus.

A multidisciplinary approach to treating child neglect

Although the multidisciplinary team approach is useful in treating child abuse and neglect, it is underutilized in the first instance and rarely employed in the second. The authors discuss the rationale, process, function, and effectiveness of such a team in dealing with child neglect.

Mixed infection with human cytomegalovirus and human polyomavirus (BKV)

Mixed infection, the infection of a single cell by two distinguishable viruses, has been demonstrated electron microscopically in human embryo lung (HEL) and human embryo kidney (HEK) cells infected with human cytomegalovirus (HCMV) and human polyomavirus (BKV). There was no evidence of enhancement of HCMV by BKV in either cell system; however, in HEL cells under certain conditions, HCMV enhanced the growth rate of BKV. Since both BKV and HCMV are often found in the urine of immunosuppressed patients, the enhancement of BKV by HCMV may be of clinical significance.
