Epidemiology of human immunodeficiency virus-associated opportunistic infections in the United States in the era of highly active antiretroviral therapy.

The incidence of nearly all AIDS-defining opportunistic infections (OIs) decreased significantly in the United States during 1992-1998; decreases in the most common OIs (Pneumocystis carinii pneumonia ¿PCP, esophageal candidiasis, and disseminated Mycobacterium avium complex ¿MAC disease) were more pronounced in 1996-1998, during which time highly active antiretroviral therapy (HAART) was introduced into medical care. Those OIs that continue to occur do so at low CD4+ T lymphocyte counts, and persons whose CD4+ counts have increased in response to HAART are at low risk for OIs, a circumstance that suggests a high degree of immune reconstitution associated with HAART. PCP, the most common serious OI, continues to occur primarily in persons not previously receiving medical care. The most profound effect on survival of patients with AIDS is conferred by HAART, but specific OI prevention measures (prophylaxis against PCP and MAC and vaccination against Streptococcus pneumoniae) are associated with a survival benefit, even when they coincide with the administration of HAART. Continued monitoring of incidence trends and detection of new syndromes associated with HAART are important priorities in the HAART era.

Clinical, Virologic, and Immunologic Follow-Up of Convalescent Ebola Hemorrhagic Fever Patients and Their Household Contacts, Kikwit, Democratic Republic of the Congo

A cohort of convalescent Ebola hemorrhagic fever (EHF) patients and their household contacts (HHCs) were studied prospectively to determine if convalescent body fluids contain Ebola virus and if secondary transmission occurs during convalescence. Twenty-nine EHF convalescents and 152 HHCs were monitored for up to 21 months. Blood specimens were obtained and symptom information was collected from convalescents and their HHCs; other body fluid specimens were also obtained from convalescents. Arthralgias and myalgia were reported significantly more often by convalescents than HHCs. Evidence of Ebola virus was detected by reverse transcription-polymerase chain reaction in semen specimens up to 91 days after disease onset; however, these and all other non-blood body fluids tested negative by virus isolation. Among 81 initially antibody negative HHCs, none became antibody positive. Blood specimens of 5 HHCs not identified as EHF patients were initially antibody positive. No direct evidence of convalescent-to-HHC transmission of EHF was found, although the semen of convalescents may be infectious. The existence of initially antibody-positive HHCs suggests that mild cases of Ebola virus infection occurred and that the full extent of the EHF epidemic was probably underestimated.

Update: Interim Guidance for Health Care Providers Caring for Women of Reproductive Age with Possible Zika Virus Exposure — United States, 2016

CDC has updated its interim guidance for U.S. health care providers caring for women of reproductive age with possible Zika virus exposure to include recommendations on counseling women and men with possible Zika virus exposure who are interested in conceiving. This guidance is based on limited available data on persistence of Zika virus RNA in blood and semen. Women who have Zika virus disease should wait at least 8 weeks after symptom onset to attempt conception, and men with Zika virus disease should wait at least 6 months after symptom onset to attempt conception. Women and men with possible exposure to Zika virus but without clinical illness consistent with Zika virus disease should wait at least 8 weeks after exposure to attempt conception. Possible exposure to Zika virus is defined as travel to or residence in an area of active Zika virus transmission ( http://www.cdc.gov/zika/geo/active-countries.html), or sex (vaginal intercourse, anal intercourse, or fellatio) without a condom with a man who traveled to or resided in an area of active transmission. Women and men who reside in areas of active Zika virus transmission should talk with their health care provider about attempting conception. This guidance also provides updated recommendations on testing of pregnant women with possible Zika virus exposure. These recommendations will be updated when additional data become available.

Health-Related Beliefs and Decisions about Accessing HIV Medical Care among HIV-Infected Persons Who Are Not Receiving Care

In the United States, the publically supported national HIV medical care system is designed to provide HIV medical care to those who would otherwise not receive such care. Nevertheless, many HIV-infected persons are not receiving medical care. Limited information is available from HIV-infected persons not currently in care about the reasons they are not receiving care. From November 2006 to February 2007, we conducted five focus groups at community-based organizations and health departments in five U.S. cities to elicit qualitative information about barriers to entering HIV care. The 37 participants were mostly male (n = 29), over the age of 30 (n = 34), and all but one had not received HIV medical care in the previous 6 months. The focus group discussions revealed health belief-related barriers that have often been overlooked by studies of access to care. Three key themes emerged: avoidance and disbelief of HIV serostatus, conceptions of illness and appropriate health care, and negative experiences with, and distrust of, health care. Our findings point to the potentially important influence of these health-related beliefs on individual decisions about whether to access HIV medical care. We also discuss the implications of these beliefs for provider-patient communication, and suggest that providers frame their communications with patients such that they are attentive to the issues identified by our respondents, to better engage patients as partners in the treatment process.

Aging cohort of perinatally human immunodeficiency virus-infected children in New York City

BACKGROUND New York City (NYC) pediatricians are now caring for fewer HIV-infected infants and more school age children and adolescents than earlier in the epidemic. METHODS Clinical, laboratory and demographic data were abstracted from medical records at 10 NYC centers participating in the CDC Pediatric Spectrum of HIV Disease project. Pediatric AIDS cases and HIV-related deaths reported to the NYC Department of Health were examined. RESULTS Median age of HIV-infected children in care increased from 3 years in 1989 to 1991 to 6 years in 1995 to 1998. The number of HIV-infected women giving birth in NYC declined 50% from 1990 to 1997 (1630 to 831); increasing numbers were identified prenatally (14% in 1989; 78% after 1995); and most received prenatal zidovudine prophylaxis (73% in 1997). Estimated perinatal transmission decreased to 10% by 1997. Improved identification of seropositive status in infants was associated with an increased proportion of infected infants receiving Pneumocystis carinii pneumonia (PCP) prophylaxis, 84% in 1997. AIDS free survival was longer for children born 1995 to 1998 than for those born before 1995, P = 0.004. In 1998 among children with advanced immunosuppression (CDC category 3), 66% were prescribed 3 or more antiretroviral medicines and 88% received PCP prophylaxis. Citywide AIDS cases and HIV-related deaths fell precipitously beginning in 1996. CONCLUSIONS Based on the observations of this study, the cohort of NYC HIV-infected children in care is aging, associated with a decline in new HIV infections, high rates of PCP prophylaxis and increased time to AIDS. Falling HIV-related deaths citywide support these observations.

HIV testing factors associated with delayed entry into HIV medical care among HIV-infected persons from eighteen states, United States, 2000-2004.

Despite the importance of timely entry into care after HIV diagnosis, the timing of care entry has not been described recently in a large, diverse population of persons with HIV. Dates of HIV diagnosis and entry into HIV care were obtained by interview of HIV-infected adults, most of whom had entered care for HIV, in 18 U.S. states from 2000 through 2004. Time to care entry was analyzed as a dichotomous variable; delayed care entry was defined as care entry greater than 3 months after HIV diagnosis. Multivariable logistic regression models were used to describe HIV testing-related factors associated with delayed care entry. Among 3942 respondents, 28% had delayed care entry. Diagnostic testing-related characteristics associated with delayed care entry included anonymous and first-time HIV testing. Providers of HIV testing should be aware that those who test positive anonymously and those whose first HIV test is positive may have increased risk for delayed HIV care entry. Developing programs that reinforce timely linkage to HIV care, targeted at those at increased risk for delaying care entry, should be a public health priority.

Human immunodeficiency virus-infected adolescents: a descriptive study of older children in New York City, Los Angeles County, Massachusetts and Washington, DC.

Background. Children infected with HIV are entering adolescence with challenging and changing medical and social needs. Through chart review we describe certain medical and social characteristics of adolescents who acquired HIV as children. Methods. HIV‐infected children 12 years of age and older in 1995 were monitored through the Pediatric Spectrum of HIV Disease study from four US sites. In addition to standard 6‐month medical chart reviews, a special chart abstraction in 1997 collected available psychosocial and sexual history information. Results. A total of 131 adolescents HIV‐infected as children were studied: 52 infected perinatally; 44 infected through a contaminated blood transfusion; 30 through receipt of contaminated blood products for hemophilia; and 5 with unknown transmission mode. Mean age at last medical contact was 15.5 years, 67% were Hispanic or African‐American, 12% were employed, 66% attended regular school, 66% knew their HIV status and 48% (8% for the perinatally infected) lived with their biologic mother. Information on sexual activity showed that 18% had sexual relations, 28% did not and for 53% sexual activity was not recorded in the medical chart. Four percent used illicit drugs, which along with sexual activity showed a positive association with age. Forty‐two percent had an AIDS‐defining opportunistic infection, and 56% had a recent CD4+ lymphocyte count <200 cells/&mgr;l. Conclusions. Adolescents in this study represent a heterogeneous group of surviving HIV‐infected children some of whom are sexually active and potential sources of HIV transmission. Clinicians who treat HIV‐infected and high risk adolescents face the challenges of providing care and prevention services appropriate to adolescent development.

Lack of Definitive Severe Mitochondrial Signs and Symptoms among Deceased HIV-Uninfected and HIV-Indeterminate Children ≤ 5 Years of Age, Pediatric Spectrum of HIV Disease Project (PSD), USA

Abstract: Background: In response to recent reports of mitochondrial dysfunction in HIV‐uninfected infants exposed to antiretroviral (ARV) prophylaxis, the Perinatal Safety Review Working Group reviewed deaths in five large HIV‐exposed perinatal cohorts in the United States to determine if similar cases of severe mitochondrial toxicity could be detected. We describe the results of this review for the PSD cohort.

Serologic Survey among Hospital and Health Center Workers during the Ebola Hemorrhagic Fever Outbreak in Kikwit, Democratic Republic of the Congo, 1995

From May to July 1995, a serologic and interview survey was conducted to describe Ebola hemorrhagic fever (EHF) among personnel working in 5 hospitals and 26 health care centers in and around Kikwit, Democratic Republic of the Congo. Job-specific attack rates estimated for Kikwit General Hospital, the epicenter of the EHF epidemic, were 31% for physicians, 11% for technicians/room attendants, 10% for nurses, and 4% for other workers. Among 402 workers who did not meet the EHF case definition, 12 had borderline positive antibody test results; subsequent specimens from 4 of these tested negative. Although an old infection with persistent Ebola antibody production or a recent atypical or asymptomatic infection cannot be ruled out, if they occur at all, they appear to be rare. This survey demonstrated that opportunities for transmission of Ebola virus to personnel in health facilities existed in Kikwit because blood and body fluid precautions were not being universally followed.

HIV stigma experienced by young men who have sex with men (MSM) living with HIV infection.

Stigma can compromise the health of persons living with HIV. Although HIV is increasingly affecting young men who have sex with men (MSM), little is known about their experiences with HIV stigma. We used narrative data to examine HIV stigma experienced by young MSM living with HIV. Data came from 28 qualitative interviews with young MSM. We used inductive content analysis to identify themes across these interviews. Participants commonly discussed negative perceptions and treatment of persons living with HIV. Stigma could result in nondisclosure of HIV status, internalized stigma, and avoidance of HIV-related things. Some men discussed strategies that might combat stigma. Findings suggest that HIV stigma might challenge young MSMs health by undermining health-conducive resources (e.g., social support) and contributing to HIV vulnerability. Interventions that counteract HIV stigma may help to create environments that promote well-being among young MSM living with HIV.
