Using the Revised Centers for Disease Control and Prevention Staging System to Classify Persons Living With Human Immunodeficiency Virus in New York City, 2011-2015.

The proportion of persons living with human immunodeficiency virus (HIV) in New York City in stage 1 (CD4 ≥ 500 cells/mm) increased from 50.6% in 2011 to 59.6% in 2015. The revised Centers for Disease Control and Prevention staging system of HIV infection is a useful tool with which to classify persons living with HIV.

Directriz para reducir el riesgo de transmisión de mycobacterium abscessus durante la práctica clínica odontológica / Guideline to reduce the risk of transmission of mycobacterium abscessusin clinical dental practice

Las medidas de bioseguridad están predestinadas a reducir el riesgo de transmisión de microorganismos a partir de fuentes de infección reconocidas o no reconocidas en clínicas dentales vinculadas con lacontaminación de los materiales, aparatos y/o instrumentos. Un microorganismo reemergente es el Mycobacterium abscessus, que es unabacteria ambiental que puede ocasionar problemas de salud muy serios, por lo que debe ser controlada y prevenida su transmisión.

Biosafety measures are designed to reduce the risk of transmission ofmicroorganisms from recognized or unrecognized sources of infectionin dental procedures associated with the contamination of materials,apparatus, and/or instruments. One reemerging microorganism isMycobacterium abscessus, which is an environmental bacterium thatcan cause serious health problems and therefore needs to be controlledand prevented.

Manifestaciones de la cavidad bucal por infección del virus de la inmunodeficiencia humana: reporte de caso clínico / Oral manifestations of the HIV virus: report of a clinical case

Las manifestaciones orales por la infección del virus de la inmunode-ficiencia humana son en ocasiones el primer signo de la enfermedad yen muchos casos un indicador de la progresión de la infección hacia elsíndrome de inmunodeficiencia adquirida. Las ulceraciones indoloras,diferentes tipos de gingivitis agresivas y la leucoplasia vellosa, se desarrollan muy fácilmente en individuos cuyo sistema inmunológico está comprometido, como el de los pacientes que sufren del virus deinmunodeficiencia adquirida.

Oral manifestations caused by the human immunodefi ciency virusare often the fi rst indication that the person is infected and oftenan indicator of its progression into AIDS. Painless ulcers, assortedtypes of aggressive gingivitis, and hairy leukoplakia develop easilyin individuals whose immune system is compromised, such as thoseinfected with HIV.

Prevalence of oral mucosal lesions and related factors in 200 HIV+/AIDS Iranian patients.

BACKGROUND: Human immunodeficiency virus infection is a worldwide problem, which affects both developed and developing countries the same. Oral lesions related to this disease are important because they affect the patient's quality of life. In developed countries, these lesions are well classified, but fewer reports on this subject are available in developing countries. Regarding the wide range of oral lesions and lack of solid status in Iran, this study has been performed on the prevalence of oral mucosal lesions and related factors in human immunodeficiency virus positive/acquired immune deficiency syndrome patients referred to behavioural disease management centres of Shahid Beheshti University in 2008-2009, Tehran. METHODS: This descriptive cross-sectional study was performed by means of observations, clinical examination, completing questionnaire and also evaluating the 200 patients' medical records to find oral mucosal lesions. Sampling was made by sequential method and after recording the finding a SPSS (version 16) software, and ordinal regression, Fisher and k^2 tests were used to analyse the results. RESULTS: One hundred and forty-nine of 200 human immunodeficiency virus positive/acquired immune deficiency syndrome patients (193 men and 7 women) had oral lesions (74.5%). Oral candidiasis (22%), linear gingival erythema (16.55%) and lymphadenopathy (13.5%) were the most common lesions. CONCLUSION: With respect to the resulted prevalence in this study (74.5%), early detection of oral lesions must be emphasized on the diagnosis and early management of human immunodeficiency virus positive/acquired immune deficiency syndrome patients.

[AIDS and transmissible opportunistic diseases in the Brazilian border area]. / AIDS e doenças oportunistas transmissíveis na faixa de fronteira Brasileira.

INTRODUCTION: Person-to-person transmission of HIV and other communicable diseases may be associated with human geographic mobility. This article evaluated the incidence of transmissible opportunistic diseases among AIDS cases that had been reported by municipalities in the Brazilian border area. METHODS: Brazilian border area municipalities were grouped into three cultural regions; the source data was AIDS cases registered with the Ministry of Health from 1990 to 2003, which were classified according to CDC-adapted, Rio de Janeiro/Caracas and death criteria; detected communicable opportunistic diseases were categorized into groups according to transmission: 1) inhalation agent; 2) contaminated water and/or food ingestion, and 3) interpersonal contact. The descriptive evaluation considered cultural region, years of schooling, sex and age group. RESULTS: Different AIDS incidence patterns were observed among groups of opportunistic diseases in each cultural region. The extreme southern region showed the greatest incidence of AIDS; the absolute incidence of female cases was greatest in the category of heterosexual transmission; the number of male cases was greatest among intravenous drug users; transmission was most frequent in the interpersonal contact group, particularly incidences of candidiasis; tuberculoses and pneumonias were most frequent in the inhalation agent transmission group; the contaminated water/food ingestion transmission group showed an unchanged pattern of absolute incidence. CONCLUSIONS: The Brazilian border area is a very important and heterogeneous geographic phenomenon; AIDS programs must recognize different cultural geographies.

AIDS e doenças oportunistas transmissíveis na faixa de fronteira Brasileira / AIDS and transmissible opportunistic diseases in the Brazilian border area

INTRODUÇÃO: A transmissão do HIV e de outras doenças transmissíveis, de pessoa a pessoa, pode ser associada à mobilidade humana. Este trabalho avaliou a incidência de doenças oportunistas transmissíveis entre os casos de AIDS, nos municípios da faixa de fronteira brasileira. MÉTODOS: Os municípios da faixa de fronteira brasileira foram agrupados em três regiões culturais; foram consideradas as notificações feitas ao Ministério da Saúde, entre 1990 e 2003, que tenham sido feitas com os critérios de definição CDC adaptado, Rio de Janeiro/Caracas e óbito; as doenças oportunistas detectadas foram agrupadas de acordo com o tipo de transmissão: 1) inalação do agente; 2) ingestão de água/alimento contaminado e 3) contato interpessoal. A análise descritiva considerou regiões culturais, anos de escolaridade, categoria de transmissão, sexo e faixa etária. RESULTADOS: Houve diferentes padrões de incidência de AIDS nos grupos de doenças oportunistas em cada região cultural. A região extremo-sul apresentou a maior incidência de AIDS; o número de casos de AIDS do sexo feminino foi maior na categoria heterossexual; o número de casos de AIDS do sexo masculino foi maior entre usuários de drogas injetáveis; as doenças transmitidas pelo contato interpessoal foram as mais frequentes, destacando a incidência de monilíases; a tuberculose e a pneumonia foram as mais frequentes dentre as doenças transmitidas pela inalação do agente; as doenças transmitidas pela ingestão de água/alimentos contaminados mostraram um padrão de incidência estável. CONCLUSÕES: A fronteira brasileira é um espaço geográfico importante e heterogêneo; o enfrentamento da AIDS deve reconhecer as diferentes geografias culturais.

Opportunistic infections in HIV disease.

Since the emergence of the HIV pandemic in the 1980s, there have been great advances in the treatment of HIV through potent and effective antiretroviral therapy. This has led to HIV-infected individuals presenting with fewer opportunistic infections and, subsequently, leading longer lives in better health. Nevertheless, there are HIV-positive people in both high- and low-resource settings who may present late with marked immunodeficiency or have no access to adequate medical care and antiretroviral therapy. Within these populations, opportunistic infections rate still remain unacceptably high. This article outlines the variety of opportunistic infections that can be seen in clinical practice, and highlights the way in which these infections can be pre-empted, diagnosed and treated according to best practice guidelines.

Mortality due to systemic mycoses as a primary cause of death or in association with AIDS in Brazil: a review from 1996 to 2006.

Deaths caused by systemic mycoses such as paracoccidioidomycosis, cryptococcosis, histoplasmosis, candidiasis, aspergillosis, coccidioidomycosis and zygomycosis amounted to 3,583 between 1996-2006 in Brazil. When analysed as the underlying cause of death, paracoccidioidomycosis represented the most important cause of deaths among systemic mycoses (approximately 51.2%). When considering AIDS as the underlying cause of death and the systemic mycoses as associated conditions, cryptococcosis (50.9%) appeared at the top of the list, followed by candidiasis (30.2%), histoplasmosis (10.1%) and others. This mortality analysis is useful in understanding the real situation of systemic mycoses in Brazil, since there is no mandatory notification of patients diagnosed with systemic mycoses in the official health system.

Opportunistic infections and HIV clinical disease stage among patients presenting for care in Phnom Penh, Cambodia.

This prospective, cross-sectional study sought to assess the spectrum of HIV-associated complications and disease stage among individuals presenting for first-time care in Phnom Penh, Cambodia between November 2001 and September 2002. One hundred patients participated in this study. All study participants presented with advanced stages of HIV disease. Seventy-four percent of the subjects had CD4 cell counts <50 cells/mm3. Tuberculosis was the most common AIDS-defining illness among participants, with a prevalence of 43%. A spectrum of other opportunistic infections, including cryptosporidiosis (13%), severe bacterial infections (12%), cryptococcosis (12%), and Pneumocystis jiroveci pneumonia (10%), was identified. These findings underscore the need for widespread HIV treatment and prevention in this setting. Increased screening for HIV and routine health maintenance for those infected are urgently needed in order to facilitate management of both opportunistic infections and the secondary prevention of HIV infection.

HIV superinfection.

Worldwide, 16 cases of HIV-1 superinfection in humans have been reported since 2002. Superinfection is defined as the reinfection of an individual who already has an established infection with a heterologous HIV strain. Controversy exists surrounding superinfection, because it has implications concerning our understanding of worldwide HIV diversity, individual immunity and disease progression, and vaccine development. Here, we review the current understanding of HIV superinfection.

CDC issues guidelines on treating OIs among adults. ART is cornerstone of treatment plan.

The CDC has confirmed that in the age of antiretroviral therapy clinicians may choose to treat some opportunistic infections (OIs) less aggressively. The CDC's recent guidelines emphasize the importance of antiretroviral therapy in reducing the incidence of OIs, particularly in individuals who have a CD4 t-cell count of less than 200 cells. But they also confirm that some OI treatment might pose more risks than benefits.

Clinical profile of HIV in India.

The clinical course of human immunodeficiency virus (HIV) disease and pattern of opportunistic infections varies from patient to patient and from country to country. The clinical profile of HIV disease in India includes a wide range of conditions like tuberculosis, cryptococcal meningitis, popular pruritic eruptions, and cytomegalovirus retinitis, among others. Tuberculosis is the most common opportunistic infection in Indian patients with HIV. Occurrence of various AIDS-associated illnesses determines disease progression. Mean survival time of Indian patients after diagnosis of HIV is 92 months. In this review, we discuss the clinical profile of HIV disease through an organ system-based approach. With the availability of antiretroviral therapy at lower cost, the clinical profile of HIV disease in India is now changing to include drug-related toxicities and immune reconstitution syndrome.

Progress in diagnosis of opportunistic infections in HIV/AIDS.

The impact of HIV/AIDS is different in developed and developing countries including India. Limited access to health care facilities, lack of infrastructure for diagnostic set up and cost of anti retroviral therapy are some of the reasons. Early accurate diagnosis of opportunistic infections (OIs), the common presenting symptom of the patients, is the key for success of effective management. This review attempts an overview of few of the important OIs with which majority of Indian patients present in the clinics. Emphasis has been on conventional method of diagnostic approach, which is possible in most of the diagnostic laboratory set up in India. Awareness of the disease and maintenance of high index of clinical suspicion are required. An integrated approach to patient management with active interaction between clinicians and microbiologists would be highly beneficial. Introduction of routine in vitro antimicrobial testing system especially for Candida sp, Cryptococcus sp and Mycobacterium sp, is also important, in order to obtain a baseline data on the susceptibility pattern, which not only have therapeutic relevance, but also can predict in advance, any shift in these patterns in the Indian population. Administrative support for the skill development of personnel, facility for data preservation and telemedicine can extend the diagnostic expertise to the remote areas, without affecting the patients mobility.
