History of cigarette smoking and heart transplant outcomes

Background: Active cigarette smoking (CS) is a contraindication for Orthotopic Heart Transplantation (OHT) with a recommendation that HT candidates be free from CS for at minimum 6 months prior to HT. Animal studies have shown that a history of CS is associated with increased risk of allograft rejection, but few studies have examined the association of past CS and HT outcomes. Methods: Data were analyzed from HT recipients captured in the United Network for Organ Sharing (UNOS) transplant registry. Adults aged 18–79 who underwent HT from 1987 to 2018 and with data for all covariates (N = 32,260) were included in this study. The cohort was categorized by past smoking history (CS vs non-CS). Post-transplant outcomes of interest included survival, graft failure, treated rejection, malignancy and hospitalization for infection. Baseline characteristics were compared between the two groups using the chi-squared analysis. Unadjusted associations between CS and patient survival were determined using the Kaplan-Meier estimations and confounding was addressed using multivariable Cox proportional hazards models. Results: HT recipients with a history of CS were older (55 vs 50, p = <0.0001), more likely to be Caucasian (75.7 vs 62.3, p = <0.0001), male (81.7 vs 68.2, p =< 0.0001), and diabetic (27.4 vs 24.4, p =< 0.0001). CS was associated with significantly worse survival (HR: 1.23, p < 0.0001). A history of CS was also associated with increased risk of acute rejection (OR: 1.20, p < 0.0001), hospitalization for infection (OR:1.24, p < 0.0001), graft failure (OR:1.23, p < 0.0001) and post-transplant malignancy (OR:1.43, p < 0.0001). Conclusion: A history of CS is associated with increased risk of adverse events post OHT.

Adequacy of testing, empiric treatment, and referral for adult male emergency department patients with possible chlamydia and/or gonorrhoea urethritis

This study evaluated the adequacy of testing, empiric treatment and referral for further evaluation of adult male emergency department (ED) patients with possible chlamydia and/or gonorrhoea urethritis. Of 968 adult male ED patients, 84% were tested for chlamydia and gonorrhoea, 16% for HIV and 27% for syphilis; 92% received empiric treatment for chlamydia and gonorrhoea and 71% were referred for further evaluation; of those tested, 29% were infected with chlamydia, gonorrhoea or both; and 3% of those tested had a positive syphilis test. The results of logistic regression modelling indicated that testing, treatment and referral were not related to a history of sexual contact with someone known to have a sexually transmitted disease or to the patient's ultimate diagnosis of a laboratory-confirmed infection. Compliance with Centers for Disease Control and Prevention (CDC) recommendations for chlamydia and gonorrhoea testing and treatment regimens was high, but was poor for HIV testing. More explicit guidance from CDC regarding syphilis testing and referral for further evaluation is needed.

A model of integrated primary care for HIV-positive patients with underlying substance use and mental illness

There is a high burden of underlying substance use and mental illness in HIV-infected populations. HIV-care settings provide an important opportunity to assess substance and mental health needs among HIV-positive patients and to provide or make referrals for appropriate treatment services. In 2003, with funding from the Center for Substance Abuse Treatment (CSAT), we developed a model of integrated substance-use counselling and referral for treatment within a primary care HIV-care setting at The Miriam Hospital in Providence, Rhode Island. The project uses a multidisciplinary approach to provide linkage to treatment services for substance use and mental illness as well as to help participants with social service needs, such as housing and medical coverage, to ensure continuity of care and optimal HIV treatment adherence. Twelve percent of the 965 HIV-infected patients in care at our center have been enrolled in the project. Of these, all have a current substance-use disorder and 79.3% have been diagnosed with a mental illness. In addition, most participants are hepatitis C-positive (HCV) (65.5%). The majority of participants are on antiretroviral therapy (76.7%). Participants have been referred for the following treatment modalities: intensive outpatient services, methadone, buprenorphine, outpatient services and residential as well as individual and group counselling. Our model has been successful in assessing the substance-use and mental health needs of HIV-infected individuals with numerous co-morbidities and referring them for ancillary medical and social services.

Heroin use in adolescents and young adults admitted for drug detoxification

PURPOSE

To examine heroin use and associated morbidity in young adults undergoing drug detoxification.

METHODS

A retrospective chart review of all persons (ages 18-25) admitted to either of the two state-funded detoxification facilities in Rhode Island was conducted between June 1998 and June 1999. Only those reporting heroin as a primary drug were included in this study (N=201).

RESULTS

Clients were largely male (64%), and white (79%), with a mean age of 22. Of those that reported heroin as their primary drug, 62% used primarily by injection. Mean age of initiation for heroin use was 18.3 years. Twenty-two percent reported a psychiatric diagnosis, and 80% reported a substance-abusing family member. Injection, previous overdose, and a mother with a history of substance use were associated with early initiation of heroin use.

CONCLUSIONS

The majority of young adults with heroin addiction undergoing detoxification began using heroin during late adolescence. Concurrence of psychiatric and medical diagnoses with heroin addiction was common, and may contribute to the severity of drug use. Efforts to identify risk factors for heroin and other injection drug use in adolescents and young adults will be critical for the design of effective interventions to prevent injection drug use and its associated morbidities.

Risk factors for syphilis among incarcerated women in Rhode Island

Syphilis remains a significant problem in the United States. The prison environment is an ideal location to identify and treat syphilis. We undertook this study to describe the correlates and risk factors for syphilis among incarcerated women in Rhode Island. The study design was a review of all cases of syphilis identified through routine screening in the state prison and a case control study. Between 1992 and 1998, among 6,249 incarcerated women, 86 were found to have syphilis; of these, 29 were primary and secondary cases representing 49% of infectious cases of syphilis in women in the state. The prison environment offers a unique opportunity for the diagnosis and treatment of syphilis.

Successful linkage of medical care and community services for HIV-positive offenders being released from prison

Human immunodeficiency virus (HIV) infection is more prevalent among the incarcerated than the general population. For many offenders, incarceration is the only time that they may access primary care. Project Bridge is a federally funded demonstration project that provides intensive case management for HIV-positive ex-offenders being released from the Rhode Island state prison to the community. The program is based on collaboration between colocated medical and social work staff. The primary goal of the program is to increase continuity of medical care through social stabilization; it follows a harm reduction philosophy in addressing substance use. Program participants are provided with assistance in accessing a variety of medical and social services. The treatment plan may include the following: mental illness triage and referral, substance abuse assessment and treatment, appointments for HIV and other medical conditions, and referral for assistance to community programs that address basic survival needs. In the first 3 years of this program, 97 offenders were enrolled. Injection drug use was reported by 80% of those enrolled. There were 90% followed for 18 months, 7% moved out of state or died, and 3% were lost to follow-up. Reincarceration happened to 48% at least once. Of those expressing a need, 75% were linked with specialty medical care in the community, and 100% received HIV-related medical services. Of those expressing a need for substance abuse treatment, 67% were successful in keeping appointments for substance abuse treatment within the community. Project Bridge has demonstrated that it is possible to maintain HIV-positive ex-offenders in medical care through the provision of ongoing case management services following prison release. Ex-offenders will access HIV-related health care after release when given adequate support.

Syringe prescription to prevent HIV infection in Rhode Island: a case study

Injection drug users (IDUs) are a population at high risk for many diseases, including AIDS, and are clearly in need of medical and substance abuse treatment. Access to sterile syringes is critical for lowering the risk of transmission of HIV and other blood-borne pathogens among IDUs. Previously tried strategies include needle exchange programs and changing laws to allow the legal purchase and possession of syringes. An alternative strategy is to have physicians prescribe syringes to IDUs. To the best of our knowledge, this has previously been tried by only a few physicians in rare situations and never on a programmatic basis. This report describes the genesis of physician's syringe prescription in Rhode Island and some of the lessons learned to date. Because of the illicit nature of drug use, a tremendous amount of mistrust and fear on the part of IDUs often leads to poor interaction with the medical establishment. Prescription of syringes by a physician can serve as a tool for reaching out to a high-risk and often out-of-treatment population of drug users. It is a way for the health care community to tap into drug-using networks and bring those populations into a medical care system.

Factitious HIV syndrome in young women

Factitious HIV infection has been observed at our center in women presenting with a false history of HIV/AIDS. In a 2-year period, 4 women presented for HIV-related care, indicating they were HIV-seropositive, while repeated serologic testing revealed no evidence of HIV infection. In all cases, the women were either quite angry or appeared surprised when told that they did not have HIV infection. A common denominator in all 4 women was a history of prolonged sexual, physical, or emotional abuse. Three of the 4 had been to other physicians, changing doctors as soon as the absence of HIV infection was established. Appropriate psychiatric support is an important aspect in care of these women, although it may not be accepted. All presentations of HIV infection should be confirmed either by identifying hard-copy data of HIV test results or by retesting all patients before evaluation and treatment of presumed HIV-related illnesses.

Prescribing syringes to prevent HIV: a survey of infectious disease and addiction medicine physicians in Rhode Island

This article describes the assessment of physicians' attitudes and practices regarding prescribing syringes to injection drug users (IDUs). A brief, anonymous, self-administered questionnaire was sent to all Infectious Disease and Addiction Medicine specialists in Rhode Island. Of 49 eligible physicians, 39 responded (response rate 80%). Most (95%) indicated that there is a legitimate medical reason for IDUs to obtain sterile syringes. Many (71%) agreed that they would prescribe syringes to prevent disease in IDUs if it were clearly legal to do so. We can conclude that physician syringe prescription to IDUs may be an acceptable supplement to existing HIV prevention strategies.

Multicenter evaluation of hepatitis C RNA levels among female injection drug users

The purpose of this investigation was to identify factors that determine the blood level of hepatitis C virus (HCV) RNA. By use of a quantitative polymerase chain reaction assay, the level of HCV RNA was ascertained in stored serum samples from 676 women enrolled in a multicenter prospective investigation who were seropositive for anti-HCV antibodies. HCV RNA levels ranged from undetectable to 22.4x106 copies/mL in these women. Among the 520 women with detectable HCV RNA, levels were higher among those who were >41 years old and those who had human immunodeficiency virus (HIV) infection. After adjusting for age in a multivariate linear regression model, HCV RNA levels were more strongly associated with HIV RNA levels than with CD4(+) lymphocyte counts. However, <6% of person-to-person variance was explained by the factors evaluated. Additional research is needed to ascertain what determines the level of HCV RNA in blood.

Blood-borne and sexual transmission of human herpesvirus 8 in women with or at risk for human immunodeficiency virus infection

BACKGROUND

Human herpesvirus 8 (HHV-8), the causal agent of Kaposi's sarcoma, is transmitted sexually among homosexual men, but little is known of its transmission among women. Although HHV-8 has been detected in blood, there has been no clear evidence of blood-borne transmission.

METHODS

We identified risk factors for HHV-8 infection in 1295 women in Baltimore, Detroit, New York, and Providence, Rhode Island, who reported high-risk sexual behavior or drug use. HHV-8 serologic studies were performed with two enzyme-linked immunosorbent assays.

RESULTS

In univariate analyses, HHV-8 was associated with black race, Hispanic ethnic background, a lower level of education, and infection with syphilis, the human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV). The risk of seropositivity for HHV-8 increased with the frequency of injection-drug use (P<0.001); HHV-8 seroprevalence among the women who used drugs daily was three times that among women who never injected drugs. Among the women with a low risk of sexual transmission, HHV-8 seroprevalence was 0 percent in those who had never injected drugs and 36 percent in those who had injected drugs (P<0.001). However, injection-drug use was linked less strongly to HHV-8 infection than to infection with HBV or HCV. In a multivariate analysis, independent predictors of HHV-8 seropositivity included HIV infection (odds ratio, 1.6; 95 percent confidence interval, 1.1 to 2.2), syphilis infection (odds ratio, 1.8; 95 percent confidence interval, 1.1 to 2.8), and daily injection-drug use (odds ratio, 3.2; 95 percent confidence interval, 1.4 to 7.6).

CONCLUSIONS

Both injection-drug use and correlates of sexual activity were risk factors for HHV-8 infection in the women studied. The independent association of HHV-8 infection with injection-drug use suggests that HHV-8 is transmitted through needle sharing, albeit less efficiently than HBV, HCV, or HIV.

Plasma viral load testing in the management of HIV infection

The polymerase chain reaction assay, branched DNA assay and nucleic acid sequence-based amplification assay quantitate human immunodeficiency virus (HIV) RNA levels. Plasma viral load (PVL) testing has become a cornerstone of HIV disease management. Initiation of antiretroviral drug therapy is usually recommended when the PVL is 10,000 to 30,000 copies per mL or when CD4+ T-lymphocyte counts are less than 350 to 500 per mm3 (0.35 to 0.50 x 10(9) per L). PVL levels usually show a 1- to 2-log reduction within four to six weeks after therapy is started. The goal is no detectable virus in 16 to 24 weeks. Periodic monitoring of PVL is important to promptly identify treatment failure. When feasible, the same assay should be used for serial PVL testing in the individual patient. At least two PVL measurements usually should be performed before antiretroviral drug therapy is initiated or changed. PVL testing may be helpful in the rare instance of indeterminate HIV antibody testing, especially in a patient with recent infection.

Hepatitis B vaccination practices in state and federal prisons

OBJECTIVE

Incarcerated populations are a group at high risk for hepatitis B. About 30% of people experiencing acute hepatitis B virus infection (HBV) have a history of incarceration. Offering routine HBV vaccinations to incarcerated individuals could have a significant effect on public health. The objective of this study is to identify current vaccine practices and the perceived feasibility of routine vaccinations for hepatitis B within correctional settings.

METHOD

The authors surveyed the medical directors of state correctional facilities in all 50 states and the federal prison system regarding current HBV vaccine practices. Surveys were faxed or mailed between July 1 and September 1, 2000.

RESULTS

Thirty-five states and the federal system responded (response rate = 70.6%). These systems account for 77% of all inmates in federal or state prisons and jails. Two states give hepatitis B vaccine routinely, nine states offer no hepatitis B vaccine, and 26 states and the Federal Bureau of Prisons offer hepatitis vaccine to some inmates. Most states do not spend enough money to vaccinate even those prisoners at highest risk. Under the Vaccine for Children program, 19,520 youths could receive vaccine immediately. According to the respondents, if vaccine were available at no-cost, 25 states and the Federal Bureau of Prisons would routinely offer vaccination to all inmates.

CONCLUSIONS

Most correctional systems do not routinely offer vaccine to their incarcerated populations, but would if funds were available. There exists now a unique public health opportunity to prevent a significant proportion of new hepatitis B infections.

Laboratory testing for infection with the human immunodeficiency virus: established and novel approaches

The enzyme-linked immunosorbent assay (ELISA) and the Western blot are the primary tests for the diagnosis and confirmation of human immunodeficiency virus (HIV) infection. The ELISA, an inexpensive screening test for antibodies to HIV-1, is both sensitive and specific. The HIV-1 Western blot is a reliable confirmatory test following a repeatedly reactive ELISA. False-positive HIV-1 results with this sequence of tests are extremely rare but can occur, and test results that are inconsistent with clinical or other laboratory information should be questioned, repeated, or supplemented. The US Food and Drug Administration has also approved rapid and more accessible testing methods. Oral mucosal transudate and urine testing are noninvasive testing methods; rapid and home sample collection kits offer easier access to testing.

Report of a false-positive HIV test result and the potential use of additional tests in establishing HIV serostatus

Considering the lifelong implications of a positive human immunodeficiency virus (HIV) test result, physicians should be aware of the limitations of tests for HIV. A 43-year-old man had a reactive enzyme-linked immunosorbent assay and an indeterminate result on Western blot analysis. The results of subsequent enzyme-linked immunosorbent assay and Western blot tests were interpreted as positive, and the patient was informed that he had HIV infection. Persistently undetectable plasma HIV-1 RNA, combined with normal physical examination findings, CD4(+) cell count, and CD4/CD8 ratio, prompted further testing, which revealed that the patient was not infected with HIV. False-positive HIV test results are uncommon, but they can occur. In the appropriate clinical setting, follow-up and the use of other laboratory tests, such as determination of plasma viral load, may help identify such cases.

Physician prescribing of sterile injection equipment to prevent HIV infection: time for action

Injection drug users, their sex partners, and their children are at high risk for acquiring HIV infection and other bloodborne diseases. The risk for disease transmission in the United States is partly the result of restricted access to sterile injection equipment. Physicians and pharmacists can play an important role in providing syringe access by prescribing and dispensing syringes to patients who use injection drugs and cannot or will not enter drug treatment Prescribing and dispensing injection equipment are ethical, clinically appropriate, and fully consistent with current public health guidelines on disease prevention. An analysis of the laws of the 50 U.S. states, the District of Columbia, and Puerto Rico finds that physicians in nearly all these jurisdictions may legally prescribe sterile injection equipment to prevent disease transmission among drug-using patients and that pharmacists in most states have a clear or reasonable legal basis for filling the prescriptions. Given these medical and legal findings, physicians may wish to take a larger role in improving access to sterile injection equipment by prescribing this equipment for their patients where this practice is legal, and by joining efforts to change the law where it poses a barrier.

High street prices of syringes correlate with strict syringe possession laws

The current epidemic of injection drug use in the United States and abroad has precipitated an increase in transmission of infectious diseases, including human immunodeficiency virus (HIV), hepatitis B, hepatitis C, and human T-lymphotrophic virus II (HTLV-II) in injection drug users (IDUs) who share syringes and other injection equipment. Sharing is often due to a lack of available sterile syringes, which is, in part, a result of laws and regulations controlling the purchase and possession of syringes. These laws, in turn, raise the price of questionably sterile black market syringes, inadvertently encouraging the reuse and sharing of syringes. To date, very little information has been gathered on the street price of syringes in different communities. We surveyed 42 needle exchange programs (NEPs) in the United States in July and August 1998 to determine the street prices of syringes. The relationship among local laws regulating syringe possession, the enforcement of those laws, and street syringe prices was examined. There was a strong correlation between the presence of syringe possession laws and higher street syringe price ($2.87 vs. $1.14, p< .01). In areas with syringe possession laws, cost was significantly higher when laws were perceived to be enforced strictly ($3.66 vs. $2.08, p<.01). Street prices for syringes are an easily quantifiable indirect measure of availability of sterile syringes and may reflect syringe sharing and reuse.

Central nervous system aspergillosis in patients with human immunodeficiency virus infection. Report of 6 cases and review

Central nervous system (CNS) aspergillosis is a relatively uncommon complication of human immunodeficiency virus (HIV) infection. We describe 6 patients with the acquired immunodeficiency syndrome (AIDS) who developed CNS aspergillosis, and we review a total of 33 cases of CNS aspergillosis among HIV-infected individuals that were diagnosed by histology and/or culture. All patients were diagnosed with advanced HIV infection. Major risk factors for the disease included neutropenia and corticosteroid use. The most common presenting symptoms were nonspecific neurologic manifestations including headache, cranial or somatic nerve weakness or paresthesia, altered mental status, and seizures. The most common sites of additional Aspergillus involvement were the lungs, sinuses, ears, and orbits, while in one-fourth of the cases CNS was the only site of Aspergillus infection. The final diagnosis of CNS aspergillosis was made on autopsy in more than half the cases, and medical treatment of CNS aspergillosis was unsuccessful in all cases. CNS aspergillosis should be included in the differential diagnosis of HIV-infected patients who present with nonspecific neurologic symptoms and signs. If we take into account the much higher prevalence of invasive aspergillosis of the lungs, the findings in the present report suggest that CNS aspergillosis in HIV-infected individuals occurs more often as a result of direct extension from the sinuses, orbits, and ears than through hematogenous spread from the lungs. Physicians should be aware that the CNS might be the only site of Aspergillus involvement and include CNS aspergillosis in the differential diagnosis of HIV-infected patients presenting with focal neurologic signs and symptoms, especially when the head CT reveals hypodense lesions.

Strategies to optimize the impact of needle exchange programs

In the United States today, half of all new HIV infections are injection drug use-associated, many of which are a result of the reuse and sharing of contaminated syringes. Thus, providing access to sterile syringes for injection drug users is an important part of preventing HIV transmission. Needle exchange programs (NEPs) have been established as one successful approach to providing sterile injection equipment. The medical literature shows that these programs are effective in decreasing both syringe sharing and HIV incidence in injection drug users. In addition, many NEPs are also beneficial because they provide other injection drug use-relevant services. There are several strategies that can be adopted in order to optimize the impact of needle exchange programs, at both the community and national levels. These include establishing NEPs in communities that need them, expanding and improving those that already exist, and implementing such programs on a larger national scale with the provision of federal funds.

Adherence to antiretroviral therapy among HIV-infected methadone patients: effect of ongoing illicit drug use

Methadone maintenance patients infected with human immunodeficiency virus (HIV) currently receiving antiretroviral therapy had HIV RNA testing and were surveyed regarding their adherence to their treatment regimens. Adherence was measured using self-report on four questions relating to medication use in the last day and last month and whether the patient took "drug holidays." Of the patients (N = 42), 52% were receiving two-drug antiretroviral therapy and 48% were receiving triple therapy that included a protease inhibitor. Persons on triple therapy reported higher rates of adherence on all measures and were more likely to have undetectable HIV RNA levels than persons on dual therapy (60% vs. 50%). Ongoing illicit drug injection was the only factor significantly associated (p < .05) with multiple measure nonadherence; however, it was not associated with undetectable HIV RNA level. Levels of nonadherence were comparable to estimates from other chronic diseases, but this finding has important implications for patients receiving highly active antiretroviral therapy.

Comprehensive medical care among HIV-positive incarcerated women: the Rhode Island experience

Our objective was to characterize the clinical presentation of human immunodeficiency virus (HIV) infection among incarcerated women in a program that provides HIV testing and primary care to all state prisoners in Rhode Island. A retrospective medical chart review on all HIV-seropositive women who were incarcerated between 1989 and 1994 and had at least two medical visits with an HIV medical care provider was used. At the Rhode Island Adult Correctional Institution (ACI), under mandatory testing laws between 1989 and 1994, 28% (172 of 623) of all women were identified with HIV infection. Of the 172 women who tested seropositive in prison, 110 were included in the study. Of the 110 women followed, 84% reported injection drug use (IDU) as their primary risk factor, and 30% reported both IDU and sex work. The median CD4 count was 596/mm3, with 60% having a CD4 count >500 cells/mm3. The most common medical conditions were vaginal candidiasis, oral candidiasis, and bronchitis. Antiretroviral therapy was well accepted and followed community standards. Continuity of medical care after release was facilitated by the same physician caring for the patient in the community setting, with 83% of women following up for HIV care after release. The medical conditions noted reflect that these women are early in the course of their HIV disease when they are initially diagnosed. This comprehensive program in Rhode Island's state prison plays a central role in the diagnosis of HIV-seropositive women and provides counseling, primary medical and gynecological care, and linkage to community resources after release.

Long-term non-progression of HIV-1 in a patient coinfected with HTLV-II

A 37-year-old man coinfected with HIV-1 and human T-lymphotropic virus type II presumably through injection drug use had a high CD4+ count and low HIV viral load without anti-retroviral therapy for over six years. As an HIV long-term non-progressor, his case supports the hypothesis that coinfection with HTLV-II does not adversely affect the course of HIV disease.

The infectious complications of anabolic-androgenic steroid injection

One million individuals in the United States alone are estimated to be current or past users of anabolic-androgenic steroids. In the United States fifty-percent of anabolic-androgenic steroid users administer their compounds intramuscularly, and twenty-five percent of adolescent anabolic-androgenic steroid users share needles, placing these young adults at risk for infections related to injection. To examine the medical literature for reports of infections attributable to anabolic-androgenic steroids, we conducted a MEDLINE (1966-1998) and AIDSLINE (1980-1998) world literature review to examine all references that attributed infections to anabolic-androgenic steroid injection. Infections associated with anabolic-androgenic steroid injection include three cases of HIV, one case of hepatitis B, one case of hepatitis C, eight abscesses, and a case of fungal endophthalmitis. No cross-sectional or prospective studies exist that document the risk of infections related to anabolic-androgenic steroid injection. These serious infectious complications of anabolic-androgenic steroid injection may be avoided with education and prevention techniques. Infections occurring in anabolic-androgenic steroid users are not as common as in intravenous drug users.

Prevalence and incidence of HIV among incarcerated and reincarcerated women in Rhode Island

This study explores recent temporal trends in HIV prevalence among women entering prison and the incidence and associated risk factors among women reincarcerated in Rhode Island. Results from mandatory HIV testing from 1992 to 1996 for all incarcerated women were examined. In addition, a case control study was conducted on all seroconverters from 1989 to 1997. In all, 5836 HIV tests were performed on incarceration in 3146 women, 105 of whom tested positive (prevalence, 3.3%). Between 1992 and 1996, the annual prevalence of HIV among all women known to be HIV-positive was stable (p = .12). Age >25 years, nonwhite race, and prior incarceration were associated with seropositivity. Of 1081 initially seronegative women who were retested on reincarceration, 12 seroconverted during 1885 person-years (PY) of follow-up (incidence, 0.6/100 PY). Self-reported injection drug use (IDU; odds ratio [OR], 3.7; 95% confidence interval [CI], 1.3-10.1) was significantly associated with seroconversion, but sexual risk was not (OR, 1.1; 95% CI, 0.4-3.5). Incarceration serves as an opportunity for initiation of treatment and linkage to community services for a population that is at high risk for HIV infection.

Hepatitis B and C in the context of HIV disease: implications for incarcerated populations

HIV-infected inmates are often co-infected with hepatitis B and/or hepatitis C virus. To describe the burden of HIV in the incarcerated population today, one must consider the impact of co-infection. HIV may dramatically modify the course of viral hepatitis infection, especially chronic hepatitis C. The converse is uncertain: chronic hepatitis does not seem to accelerate HIV disease progression. In this article, we offer guidelines for selecting appropriate candidates for treatment among co-infected inmates.

Needle exchange program participation by anabolic steroid injectors, United States 1998

A significant number of people are currently misusing and abusing anabolic steroids. Hepatitis B, C, and HIV have all been documented to occur among anabolic steroid injectors (ASIs), most likely from the sharing of injection equipment. A survey was administered to 42 needle exchange programs (NEPs) from 17 states in the US to determine ASI participation. Sixty percent of the NEPs surveyed reported having at least some ASIs as participants, however, only 512 ASIs were identified among the 36,000 total monthly participants (1.4%). With the expanding number of NEPs in the US, it is possible to reach a higher proportion of ASIs with clean syringes and education, thus offering the means to prevent the spread of infection in this population.

Obstacles to needle exchange participation in Rhode Island

OBJECTIVE

This study explores obstacles to participation in needle exchange programs (NEPs) among injection drug users (IDUs) in the state of Rhode Island, U.S.A.

METHODS

A written questionnaire was administered at two Rhode Island drug detoxification sites in 1998.

RESULTS

488 self-administered surveys were completed, 226 (46.3%) respondents had injected drugs in the past 6 months. 62.1% reported sharing syringes in the past 6 months, and each syringe was used a mean of 10.7 times. Major obstacles to NEP participation were a lack of awareness of the program (25.6%), inconvenient location or hours (15.9%), and fear of identification and/or police harassment (12.2%). Non-white race was a significant predictor of being unaware of the NEP (p = .01) and not participating in the NEP (p = .03). 13.1% of IDUs who used the NEP were referred to the detoxification program by the NEP. Among all IDUs surveyed, 51.0% had participated in a NEP.

CONCLUSIONS

NEPs are important in reducing the spread of bloodborne pathogens among IDUs and are effective referral sources for drug treatment. Surveys of IDUs at sites other than NEPs, such as detoxification facilities, can identify obstacles to the use of NEPs.

Use of cerebrospinal fluid shunt for the management of elevated intracranial pressure in a patient with active AIDS-related cryptococcal meningitis

Persistently elevated intracranial pressure (ICP) is one of the most accurate predictors of a poor prognosis in patients with AIDS-related cryptococcal meningitis. We present a severe case of persistent cryptococcal meningitis in a patient with advanced AIDS, complicated by elevation of ICP. A ventriculoperitoneal shunt was placed that successfully lowered the ICP and alleviated the associated symptoms. The elevated ICP secondary to AIDS-related cryptococcal meningitis should be treated aggressively. Despite the risk of shunt complications, cerebrospinal fluid shunts can be considered in these patients if they do not respond to other treatment.

Highly active antiretroviral therapy leading to resolution of porphyria cutanea tarda in a patient with AIDS and hepatitis C

The association between HIV infection and porphyria cutanea tarda (PCT) is not well established. Since almost all HIV-infected patients with PCT previously described in the literature had additional risk factors for PCT, it is still unclear if HIV infection and not a cofactor such as hepatitis C virus is the trigger for PCT in this population. We describe a patient with AIDS and hepatitis C who developed bullous lesions due to PCT. The cutaneous lesions persisted for 18 months and resolved after he was placed on highly active antiretroviral therapy for HIV. No other therapeutic interventions were undertaken, while exposure to other known precipitants remained unchanged. During follow-up, skin lesions reappeared when the patient discontinued antiretroviral therapy, but PCT lesions again resolved after he restarted highly active antiretroviral therapy and HIV infection was controlled. This case supports the hypothesis that a direct causative relationship exists between HIV and the development of PCT.

Reduction in recidivism of incarcerated women through primary care, peer counseling, and discharge planning

Prior to release from the Rhode Island state prison, women at the highest risk for reincarceration and HIV infection are assigned to the Women's HIV/Prison Prevention Program (WHPPP), a discharge program designed to reduce the likelihood of reincarceration and HIV infection. Candidates for the WHPPP must meet at least one of three criteria: intravenous drug use or crack use, commercial sex work, or a history of prison recidivism with poor educational history and poor employment prospects. While incarcerated, the program participant develops a relationship with a physician and a social worker and establishes an individualized discharge plan. After release, the same physician and social worker continue to work with the client and assist an outreach worker in implementing the discharge plan. Data were collected from questionnaires administered to 78 women enrolled in the WHPPP between 1992 and 1995. The population in this program was primarily composed of ethnic minorities (55%), 25-35 years of age (55%), unmarried (90%), had children (72%), and displayed a variety of HIV risk behaviors. The WHPPP recidivism rates were compared with those of a mostly white (65%), similarly aged (51% were between 25 and 35 years of age) historical control group of all women incarcerated in Rhode Island in 1992. The intervention group demonstrated lower recidivism rates than the historical control group at 3 months (5% versus 18.5%, p = 0.0036) and at 12 months (33% versus 45%, p = 0.06). Assuming that recidivism is a marker for high-risk behavior, participation in the WHPPP was associated with a reduction in recidivism and in the risk of HIV disease in this very high risk group of women.

Abscess related to anabolic-androgenic steroid injection

One million individuals in the United States, predominantly males under 25 yr of age, are current or past users of anabolic-androgenic steroids. Fifty percent of these young adults administer their drugs intramuscularly, placing them at risk for infections related to injection. We present here a case report of an injection-related thigh abscess in a 26-yr-old anabolic steroid injector who did not use sterile injection technique and reported sharing multidosage vials with two other weightlifting colleagues. Reported infections associated with anabolic-androgenic steroid injection include abscesses attributable to Mycobacterium smegmatis, Staphylococcus, Streptococcus, and Pseudomonas organisms as well as HIV, hepatitis B, and hepatitis C. These infections are primarily related to nonsterile injection technique, shared injection equipment, and are avoidable with appropriate prevention techniques. Education is needed to prevent infectious complications such as abscesses and blood-borne pathogens among anabolic-androgenic steroid injectors.

Persistent parvovirus B19 related anemia of seven years' duration in an HIV-infected patient: complete remission associated with highly active antiretroviral therapy

A human immunodeficiency virus (HIV)-infected individual was first diagnosed with red blood cell aplasia due to B19 parvovirus infection in late 1989. Over the subsequent seven-year period, he received a total of 119 units of red blood cells (RBCs) and intravenous immunoglobulin every 2-3 weeks. In 1996 combination antiretroviral treatment with a protease inhibitor was initiated. He received four more units during the following two months and then required no more transfusions for the subsequent 24 months of follow-up. His CD4 count progressively increased and DNA polymerase chain reaction for parvovirus B19 became undetectable. Aggressive antiretroviral treatment may effectively diminish transfusion requirements among HIV-infected individuals with pure RBC aplasia resulting from parvovirus B19 infection.

Misdiagnosis of HIV infection by HIV-1 plasma viral load testing: a case series

BACKGROUND

The availability of sensitive assays for plasma HIV viral load and the trend toward earlier and more aggressive treatment of HIV infection has led to the inappropriate use of these assays as primary tools for the diagnosis of acute HIV infection.

OBJECTIVE

To describe limitations in the use of plasma viral load testing for the diagnosis of HIV infection.

DESIGN

Case series.

SETTING

Academic medical centers in Providence, Rhode Island, and Worcester, Massachusetts.

PATIENTS

Three persons in whom HIV infection was falsely diagnosed by plasma viral load testing.

MEASUREMENTS

Laboratory measures and clinical outcomes.

RESULTS

Two cases of false-positive results obtained by using branched-chain DNA plasma viral load assays and one case of a false-positive result obtained by using reverse transcriptase-polymerase chain reaction plasma viral load assay are reported. All three plasma viral load tests yielded positive results with low values (1254 copies/mL, 1574 copies/mL, and 1300 copies/mL). Infection with HIV was initially diagnosed in all three patients, but each patient subsequently tested negative by HIV-1 enzyme-linked immunosorbent assay and repeated plasma viral load testing.

CONCLUSION

Physicians should exercise caution when using plasma viral load assays to detect primary HIV infection, particularly when the pretest probability of infection is low.

Detection of HIV-1 nucleic acid and HIV-1 antibodies in needles and syringes used for non-intravenous injection

BACKGROUND

HIV antibodies and HIV DNA have been detected in needles and syringes that have been used for intravenous injections in HIV-infected persons. During intravenous injection, blood is typically aspirated into the lumen of the syringe. During intramuscular or subcutaneous injection, however, blood is not usually introduced into the syringe.

OBJECTIVES

To investigate the presence of HIV antibodies, HIV proviral DNA, HIV RNA, and human DNA in needles and syringes that had been used for intramuscular or subcutaneous injection in persons known to have HIV infection.

METHODS

Discarded disposable needles and syringes used by health-care personnel for medically indicated intramuscular or subcutaneous injections of HIV-infected patients were collected. Residual material was extracted from the syringes. The extracts were analyzed by enzyme immunoassay for the presence of HIV antibodies. PCR was conducted to detect HIV and human DNA, as well as HIV RNA.

RESULTS

HIV antibodies were detected in 16 (6.2%) out of 260 syringes. Human DNA or HIV-specific DNA were not detected. A second set of 80 syringes was collected to examine the presence of HIV RNA. HIV RNA was detected in three (3.8%) out of 80 syringes.

CONCLUSION

This analysis demonstrates that the risk of transmitting HIV from syringes that have been used for intramuscular or subcutaneous injection may be low, but is not zero.

Pulmonary aspergillosis and invasive disease in AIDS: review of 342 cases

Aspergillosis is an infrequent but commonly fatal infection among HIV-infected individuals. We review 342 cases of pulmonary Aspergillus infection that have been reported among HIV-infected patients, with a focus on invasive disease. Invasive pulmonary aspergillosis usually occurs among patients with <50 CD4 cells/mm3. Major predisposing conditions include neutropenia and steroid treatment. Fever, cough, and dyspnea are each present in >60% of the cases. BAL is often suggestive, but biopsy specimens are necessary for definite diagnosis. Amphotericin B is the mainstay of treatment and mortality is > 80%. Avoiding neutropenia and judicious use of steroids may be helpful in prevention. Aggressive diagnostic approach, early initiation of treatment, adequate dosing of antifungals, and close follow-up may improve the currently dismal prognosis.
