Vuxna patienters upplevelser av att leva med HIV : En litteraturstudie

Grudzinska, Maja, Öberg, Johanna January 2016 (has links)
Bakgrund: HIV (Human Immunodeficiency Virus) är en sjukdom som påverkar människors immunförsvar. Ca 30–35 miljoner människor lever med HIV i världen. HIV är en sjukdom som påverkar de drabbade både psykiskt och fysiskt. Syfte: Att beskriva vuxna patienters upplevelser av att leva med HIV med fokus på psykiska och fysiska aspekter samt beskriva hur undersökningsgruppen ser ut i de valda artiklarna. Metod: En beskrivande litteraturstudie baserat på 10 vetenskapliga artiklar med kvalitativ ansats. Databasen Cinahl användes till litteratursökningen. Huvudresultat: Resultatet i denna litteraturstudie visade att människor som lever med HIV känner rädsla, depression, oro och stress över att leva med sjukdomen. Känslorna kopplas till upplevelser av stigmatisering och diskriminering från vården och samhället. Människorna som lever med HIV är ofta rädda för hur de blir bemötta av allmänheten. Fysiska symtom som till exempel trötthet påverkar människor som lever med HIV negativt, och förmågan att leva ett normalt liv blir förhindrat. I litteraturstudien presenteras undersökningsgruppen tydligt utifrån vad författarna till de granskade studierna beskrivit. Slutsats: HIV-positiva personer kan mötas i alla vårdinsatser. Känslor av bland annat skuld och skam förekommer ofta hos personer med HIV. Som sjuksköterska är bemötandet av människor med HIV väldigt viktigt. / Background: HIV (Human Immunodeficiency Virus) is a disease that affect the human immune system. Around 30–35 million people are living with HIV in the world. HIV affects people, both mentally and physically. Aim: To describe adults/adult patients experiences of living with HIV, focusing on mental and physical aspects, and to describe how the study group looks in the selected studies. Method: A descriptive literature study, based on 10 scientific articles with qualitative approach. The database that was used to find the articles was Cinahl. Main Results: The result of this literature study shows that people living with HIV daily feel emotions of fear, depression, anxiety and stress due to living with the disease. The emotions connect directly to experiences of stigmatization and discrimination within the healthcare and community. People living with HIV are often afraid how other people will react their disease. Physical symptoms like fatigue affect their everyday life negative, and the ability to live a normal life is prevented. The study group is clearly presented based on what the authors of the audited studies describes. Conclusion: HIV-positive people can be found in all healthcare facilities. Emotions of guilt and shame often occure with people who are living with HIV. As a nurse, the attitude towards people with HIV is very important.

Exploring the trends in prevalence of human immunodeficiency virus drug resistance in South Africa over the course of the HIV epidemic

Chopera, Denis Rutendo January 2018 (has links)
Magister Public Health - MPH / Background: Antiretroviral therapy (ART) was rolled out in South Africa in the public sector in 2004 and the treatment coverage has increased over the years to 56% in 2016. The increased treatment coverage has the potential to increase the level of HIV drug resistance. Drug resistance presents a major challenge to the management of HIV infection through antiretroviral therapy at the population level. The aim of this study was to determine the impact of the public sector antiretroviral therapy rollout on the prevalence of HIV drug resistance in South Africa and the factors associated with drug resistance. Methodology: A cross-sectional analytical study was used to determine the prevalence of drug resistance before and after ART rollout. The study population was HIV infected South Africans (infected between 1996 and 2011) who were not on antiretroviral therapy. The study sample was therapy naïve HIV infected South Africans who participated in published studies conducted between 1996 and 2011. HIV DNA sequences and associated data (participants’ age, gender, geographic location and estimated year of HIV infection) were accessed through the Los Alamos HIV Database. The database contains all HIV DNA sequences and associated data from all published studies and the data was freely accessible. A descriptive analysis was carried out on the data to determine characteristics of the study sample. Drug resistance mutations were detected using Calibrated Population Resistance Program on the Stanford University HIV Drug Resistance database. The output from the Calibrated Population Resistance Program analysis were used to determine the prevalence of drug resistance mutations. Results: There were 1701 DNA sequences obtained from the Los Alamos HIV Database for the three gene regions targeted by ART (reverse transcriptase, protease and integrase). Of these, 604 (35,5%) were for reverse transcriptase, 794 (46,7%) were for protease and 303 (17,8%) were for integrase. There was overrepresentation of DNA sequences from female participants (91%). There was no significant difference in the prevalence of drug resistance mutations between 1996-2004 (before ART rollout) and 2005-2011 (after ART rollout) in all the drug classes. There was also no association between drug resistance and age as well as gender. Conclusion: The data from this study suggest that the public sector rollout of ART did not result in an increase in the prevalence of drug resistance mutations in therapy naïve HIVinfected South Africans. There is need for further studies, which have a wider coverage of the South African population.

Sexual behaviours and HIV protective practices amongst men who have sex with men (MSM) and men who have sex with men and women (MSMW) in Soweto

Dladla, Sibongile Hillaray 19 February 2014 (has links)
there is a growing body of research on men who have sex with men (MSM) and risk factors for HIV in South Africa. However, in order to develop more appropriate and relevant interventions to reduce the transmission of HIV amongst MSM and MSMW, there was a need to deepen our understanding of sexual risk behaviour and protective practices. The aim of the study was to explore the sexual risk and protective behaviour of men who have sex with men and women in Soweto, South Africa.

Factors affecting the utilisation of voluntary counselling and testing (VCT) services for HIV/AIDS in Sowa, Botswana.

Akhiwu, Patrick 17 January 2012 (has links)
Introduction Voluntary Counselling and Testing (VCT) play a crucial role in the control and management of the HIV/AIDS epidemic. It is essential to understand the factors that influence the utilisation of VCT to improve implementation of measures that encourage VCT uptake. The purpose of this study was to determine factors affecting the utilisation of Voluntary Counselling and Testing (VCT) services for HIV/AIDS in Sowa, Botswana. Methodology A cross-sectional study was carried out by collecting data from 71 randomly selected participants residing in the community of Sowa, Botswana. Open and close ended questions were used. Relevant demographic data were collected from each respondent. Univariate and multivariate analysis was done using chi square test and logistic regression models through STATA11 statistical software. Results About half of the respondents were willing to utilise the VCT services. Willingness to utilise VCT was significantly associated with the respondents' choice of VCT centres, worry about confidentiality at VCT centres, and concern about their partners' being aware of their use of VCT. The expected reactions of their partner, family and community to the use of VCT by the respondents, in addition to the willingness of respondents to inform their partners the result of their HIV test, were other factors associated with the use of VCT. Multivariate regression showed that being "not worried" (AOR 33.48; 95CI 5.63 - 199.15) about confidentiality at VCT centres predicted the willingness to use VCT. In addition, not worried that their partners were aware they had utilised VCT (AOR 7.25; 95CI 1.69- 31.14), and readiness to inform their partners about the result of their HIV test (AOR 14.96; 95CI 3.74- 59.85), predicted the willingness of respondents to utilise VCT. Similarly, the expectation of a happy reaction from partner (AOR 47.02; 95CI 3.83- 577.11) and family (AOR 45.13 95CI 3.28-620.72) on being aware the respondent had used VCT, also predicted willingness to use VCT. Conclusion This study confirmed that stigma related to VCT use and confidentiality at VCT centres influence the utilisation of VCT services. Also, concern about partner's awareness that a respondent had used VCT and the expected response of partner, family, and community, were all important influencing factors to the utilisation of voluntary counseling and HIV testing services. These issues need to be addressed in order to increase VCT uptake among individuals and the community.

Clinical outcome of HIV patients who commence antiretroviral therapy at different CD4 levels

Mothapo, Khutjo Peter January 2011 (has links)
A research report submitted to the faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Medicine (Pharmacotherapy) / Background: The decision of when to start treatment in an HIV-infected individual has always been problematic as far as CD4 count is concerned. Aims: To determine the clinical outcome of patients who commence HAART at different CD4 cell count levels. Method: Retrospective analysis of records of a cohort of patients who are received ART at workplace wellness clinics in three mines in Limpopo province from January 2003 to December 2009. Patients were divided into three groups based on their baseline, group A (CD4 <100), group B (CD4 101-200) and group C (CD4 201-250) Each patient’s data was analyzed one year after his/her commencement. Results: The percentage of patients who died in group A (16%) differs significantly from the percentage of patients who died in group B (4%) (Fisher exact test p= 0.038) and also differ significantly from the percentage of patients who died in group C (0%) (Fisher exact test p= 0.011). The percentages of patients who developed TB in the three groups are 8%, 8% and 2.9% respectively. When compared statistically, these percentages do not differ significantly (Fisher exact test p=0.059).The percentages of patients with severe bacterial pneumonia in the three groups (2%, 2% and 0% respectively) do not differ significantly (Fisher exact test p=0,276).The percentage of hospital admissions for patients in group A (18%) differ significantly from the percentage in group B (6%) and the percentage in group C (6%) (Fisher exact test p= 0.05). The percentage of patients with weight loss of more than 10% of baseline value in group A (24%) differ significantly from the percentage in group B (4%) (Fisher exact test p= 0.003) and also differ significantly to from the percentage in group C (0%) (Fisher exact test p= 0.001). The percentage of patients with undetectable viral load in group B (89%) is significantly different from the percentage in group A (69%) (Fisher exact test p= 0.03) and is also significantly different from the percentage in group C (61%) (Fisher exact test p= 0.008).The change in mean CD4 cell count was found to be statistically significant within each group (paired t test, p<0.0001), but the mean changes between the three groups (132,141 and 172) respectively, do not differ significantly (ANOVA test). Conclusion: Patients with baseline CD4 cell count of less than 100 have a poor clinical outcome when compared to patients with baseline CD4 cell count of more than 100. Efforts must be made to identify patients early before CD4 cell count fall to below 100 and preferably initiate HAART when CD4 cell count is above 200.

Salmoneloses: avaliação epidemiológica, clínica e laboratorial dos pacientes do Instituto de Infectologia Emílio Ribas com infecção por Salmonella spp. no período de janeiro de 1992 a dezembro de 2002 / Salmonellosis: epidemiological, clinical and laboratorial evaluation of the patients from \"Instituto de Infectologia Emílio Ribas\" with infection due to Salmonella spp. in the period from January 1992 to December 2002

Nascimento, João Manoel Cruz 24 April 2007 (has links)
OBJETIVOS: conhecer os perfis epidemiológico, clínico e laboratorial dos pacientes com infecção por Salmonella spp. e o perfil de sensibilidade antimicrobiana destas cepas de Salmonella spp., no Instituto de Infectologia Emílio Ribas, São Paulo (SP), no período de 1992 a 2002.MÉTODOS: revisão dos prontuários médicos dos pacientes e avaliação do perfil de sensibilidade das cepas de Salmonella ssp. pelo método de disco difusão das cepas aos antimicrobianos ciprofloxacina, ceftriaxone, cloranfenicol, ácido nalidíxico, ampicilina, sulfametoxazol-trimetropim (SMX-TMP), tetraciclina e estreptomicina. RESULTADOS: um total de 146 cepas de Salmonella spp. foram isoladas a partir de pacientes diferentes durante o período avaliado. Cento e onze (76,0%) pacientes eram do sexo masculino e 35 (24,0%), do feminino. A média de idade dos pacientes foi de 29,33 ± 12,76 anos (mínima de um ano e máxima de 70 anos). Cento e seis (72,6%) pacientes residiam na cidade de São Paulo. Em 128 (87,7%) casos, a fonte provável de contaminação por Salmonella spp. era desconhecida. A febre, diarréia, náuseas e/ou vômitos e sintomatologia respiratória estiveram presentes em, respectivamente, 111(76%), 92 (63%), 67 (45,9%) e 63 (43,2%) pacientes na admissão hospitalar. Em indivíduos HIV-positivos, os sintomas respiratórios foram mais os comuns. A maior parte das cepas foi obtida de sangue e fezes, respectivamente, 109 (74,4%) e 22 (15,1%) cepas. Trinta e cinco (24,0%) cepas eram do sorotipo Salmonella Typhi e 111 (76%), sorotipos não-Typhi, sendo os sorotipos mais comuns Enteritidis com 42 (37,8%) cepas; Typhimurium, 23 (20,7%); I,4,[5],12:i:-, 16 (14,4%) e Dublin, 16 (14,4%). Noventa e sete (66,4%) pacientes tinham sorologia para HIV positiva e seis (4,1%), negativa. Quarenta e três (29,5%) pacientes tinham sorologia anti-HIV desconhecida. Entre os 97 pacientes HIV-positivo, em 14 (14,4%), o episódio atual de salmonelose, com ou sem patologias oportunistas, foi a responsável pela descoberta da infecção pelo HIV ou desenvolvimento para a sida em indivíduos já sabidamente HIV-positivo. Os seguintes percentuais de sensibilidade foram encontrados nos antimicrobianos estudados: ciprofloxacina, 100% de sensibilidade; ceftriaxone, 99,3%; cloranfenicol, 96,6%; ácido nalidíxico, 95,2%; ampicilina, 92,5%; sulfametoxazoltrimetoprim, 91,8%; tetraciclina, 86,3% e estreptomicina, 65,8%. Trinta e oito (26,0%) pacientes evoluíram para o óbito, sendo todos HIV-positivo/AIDS (p< 0,0001) e em todos isoladas cepas de Salmonella não-Typhi (p = 0,0001). CONCLUSÕES: a ocorrência dos sorotipos Typhi e não-Typhi e a sintomatologia diferem segundo a condição sorológica para o HIV. A cultura do sangue e de fezes deve fazer parte da rotina do diagnóstico. Ciprofloxacina, ceftriaxone,cloranfenicol e ampicilina constituem opções terapêuticas adequadas para a infecção por Salmonella spp.. Foram fatores de risco para o óbito, sorologia anti-HIV positiva e o isolamento de Salmonella não-Typhi. / OBJECTIVES: knwon the epidemiological, clinical and laboratorial characteristics of the patients with infection due to Salmonella spp. and the pattern of susceptibility to antimicrobials of such isolates of Salmonella spp., from \"Instituto de Infectologia Emílio Ribas, São Paulo\" (SP), in the period of January 1992 to December 2002. METHODS: review of the patients charts and evaluation of the pattern of susceptibility from the isolates of Salmonella spp. performing the disk diffusion method to the antimicrobials ciprofloxacin, ceftriaxone, chloramphenicol, nalidixic acid, ampicillin, trimethoprim/sulfamethoxazole, tetracycline and streptomycin. RESULTS: a total of 146 isolates were obtained from different patients in the period evalueted. One-hundred and eleven (76.0%) patients were male and 35 (24.0%), female. The median age was 29.33 ± 12.76 years (range one year 70 years). One-hundred and six (72.6%) patients lived in the city of São Paulo. In 128 (87.7%) cases, the probable source of contamination with Salmonella spp. was unknwon. Fever, diarrhoea, nausea and/or vomiting and respiratory sintomatology were present, respectively, in 111(76%), 92 (63%), 67 (45.9%) and 63 (43.2%) patients at presentation. In HIV-seropositive patients, respiratory sintomatology was the most common. Most of the isolates were obtained from blood and stool, respectively, 109 (74.4%) and 22 (15.1%) isolates. Thirty-five (24.0%) isolates belonged to serotype Salmonella Typhi and 111 (76%) to non-Typhi serotypes, being the most common Enteritidis with 42 (37.8%) isolates; Typhimurium, 23 (20.7%); I,4,[5],12:i:-, 16 (14.4%) and Dublin, 16 (14.4%). Ninety-seven (66.4%) patients had HIVserology positive and six (4.1%) patients, negative. In 43(29.5%) patients, the HIV serology was unknown. Considering the 97 HIV-seropositive patients, in 14 (14,4%), the actual episode of salmonellosis, with or without oportunistic infections, was the responsible for the discovery of the HIV infection or to development to Acquired Immunodeficiency Syndrome in already known HIV-seropositive patients. The following percentages of susceptibility were found in the antimicrobials analysed: ciprofloxacin, susceptibility of 100%; ceftriaxone, 99.3%; chloramphenicol, 96.6%; nalidixic acid, 95.2%; ampicillin, 92.5%; trimethoprim/sulfamethoxazole, 91.8%; tetracycline, 86.3% and streptomycin, 65.8%. Thirtyeight (26.0%) evoluted to death, being all HIV-positive patients (p < 0.0001) with infection to non-typhoidal Salmonellae (p = 0.0001). CONCLUSIONS: the occurrence of serotypes Typhi and non-Typhi and the patients sintomatology depends on the HIV-serology. Culture of blood and stool should be part of the diagnosis. Ciprofloxacin, ceftriaxone, chloramphenicol and ampicillin are good therapeutic options for Salmonella spp. infection. HIV-serology positive and the isolation of non-Typhi Salmonella were risk factors to death.

Avaliação das subpopulações de linfócitos T CD4+, linfócitos T CD8+ e da razão CD4+/CD8+ em gatos com gengivite crônica e infectados naturalmente pelo vírus da imunodeficiência dos felinos (FIV) / Evaluation of CD4+ and CD8+ T-Lymphocytes count and CD4+:CD8+ ratio in cats with chronic gingivitis and naturally-infected with feline immunodeficiency virus (FIV)

Haipek, Katia 14 July 2006 (has links)
A gengivite crônica e intratável observada em gatos infectados pelo vírus da imunodeficiência felina (FIV) é um problema bastante freqüente na clínica de pequenos animais. O papel do FIV na etiologia da estomatite persistente ainda está por ser determinado. As manifestações orais são freqüentemente os primeiros sintomas observados em pacientes humanos infectados pelo HIV e podem ser usadas como indicadores da progressão da doença. O objetivo do presente estudo foi quantificar os linfócitos T CD4+, T CD8+ e a razão CD4+/CD8+ em uma colônia de gatos com gengivite crônica e naturalmente infectados pelo FIV. Para tanto, foram utilizados 20 gatos, todos apresentando gengivite com graus variando de 1 a 4. Desse total, 10 gatos não eram infectados pelo FIV e os outros 10 felinos eram infectados pelo FIV. Utilizou-se como controle 20 gatos sem gengivite, sendo 10 infectados pelo FIV e outros 10 não infectados pelo Retrovírus. As contagens dos linfócitos T CD4+ e CD8+ foram realizadas utilizando-se a técnica de citometria de fluxo. Os resultados obtidos demonstraram que os gatos com gengivite e infectados pelo FIV apresentaram uma contagem significativamente menor de linfócitos T CD4+ quando comparado aos gatos com gengivite e não infectados pelo FIV. Não houve diferença significativa na contagem de linfócitos T CD8+ entre os gatos com gengivite, infectados ou não pelo FIV. A razão CD4+/CD8+ também se mostrou em declínio nos gatos com gengivite e infectados pelo FIV. Concluiu-se que nas condições do presente estudo, a infecção pelo FIV compromete a resposta imunológica de felino diante da inflamação gengival. / Chronic and intractable gingivitis in FIV-infected cats is a relatively common clinical problem in veterinary practice. The role of FIV in the etiology of persistent stomatitis is still undetermined. Oral manifestations often found in HIV-infected people are frequently the first clinical sign of the infection and can be considered as an indicator of the progression of the HIV infection. The purpose of this study was to evaluate the CD4+ and CD8+ T-lymphocytes count and CD4+:CD8+ ratio in a colony of cats with chronic gingivitis. To achieve these goals, a colony of twenty domestic shorthair cats was used. All cats had some degree of gingival inflammation with scores ranging from 1 through 4. Ten cats were FIV-positive and ten were FIV-negative. As a control, twenty cats without gingivitis were used (ten cats were FIV-positive and ten were FIV-negative). CD4+ and CD8+ T-lymphocytes counts were performed by means of flow cytometry in all forty cats and results compared. The results showed that cats with gingivitis and FIV-infected had a lower CD4+ T cells count than cats with gingivitis but not FIV-infected. There was no difference in CD8+ T lymphocytes count among the cats with gingivitis infected or not with the FIV. The CD4+:CD8+ ratio was lower in cats with gingivitis and FIV-infected. One can conclude that FIV infection induces immunological disorders in cats with gingival inflammation.

Diagnóstico das lesões esofágicas em pacientes HIV-positivos utilizando a reação em cadeia da polimerase (PCR). / Diagnosis of esophageal lesions in HIV-positive patients by the polymerase chain reaction (PCR).

Colares, Jeová Keny Baima 07 December 2001 (has links)
Os pacientes infectados pelo vírus da imunodeficiência humana (HIV) freqüentemente apresentam alterações digestivas, sendo o esôfago um alvo comum de lesões estruturais. A etiologia infecciosa é a mais freqüente neste grupo de pacientes. Múltiplos agentes já foram implicados como causadores de lesões esofágicas. As infecções virais são uma das principais causas de tais lesões, sendo os vírus mais implicados o citomegalovirus (CMV) e o vírus herpes simples (HSV). Muitas lesões ulceradas permanecem sem diagnóstico etiológico, mesmo após exaustiva investigação, sendo denominadas úlceras idiopáticas ou aftosas. Os métodos de diagnóstico usuais são demorados e pouco sensíveis. Assim, nosso estudo tem como principal objetivo estudar o papel do método da reação em cadeia da polimerase (PCR) no diagnóstico destas lesões. Durante o período de outubro de 1996 a outubro de 1997, foram estudados 79 pacientes HIV-positivos, que foram submetidos ao exame de endoscopia digestiva alta por indicação clínica. Estes foram submetidos a 89 exames endoscópicos, sendo colhidas 96 biópsias, as quais foram armazenadas em nitrogênio líquido (50) ou em freezer a –70oC (46). O DNA foi extraído usando método baseado na lise hipotônica, digestão com proteinase K, extração com fenol-clorofórmio e precipitação em etanol. Uma quantidade fixa foi usada para amplificação em ciclador térmico, utilizando primers específicos para CMV, Herpesvirus, HPV, HIV, Haemophilus ducreyi, Treponema pallidum e as micobactérias M. tuberculosis, M. avium e M. intracellulare. O produto final foi submetido a uma eletroforese em gel de agarose e corado com brometo de etídeo. A endoscopia não revelou alterações esofágicas em 26 exames (29,2%). As alterações observadas foram monilíase esofágica em 33 exames (37,1%), úlceras em 22 (24,7%); esofagite em 10 (11,2%) e áreas lugol-negativas em 9 (10,1%). A PCR resultou positiva para o CMV em 19 amostras (19,8%), para o Herpes em 4 (4,2%), para o HPV em 17 (17,7%), para o HIV em 37 (38,5%) e para o H. ducreyi em 3 (3,1%). Nenhuma amostra foi positiva para o T. pallidum e para micobactérias. No estudo de 29 amostras de 22 úlceras esofágicas a PCR detectou o CMV em 9 amostras (31%), o Herpes em 3 (10,3%), o HPV em 6 (20,7%), o HIV em 19 (65,5%) e o H. ducreyi em 2 (6,9%) e em 8 (36,4%) não foi detectado nenhum agente. O CMV foi detectado com freqüência nas úlceras esofágicas, sendo difícil diferenciar se havia infecção ativa ou latente. O HIV teve uma incidência elevada nas biópsias de úlceras, o que pode sugerir um possível papel etiológico deste agente em tais lesões. O HPV foi o terceiro agente mais freqüente, mas não foi possível caracterizá-lo como causador de lesões esofágica ulceradas. A PCR apresentou potencial para tornar-se um método útil na investigação das lesões esofágicas em pacientes infectados pelo HIV. / Patients infected by Human Immunodeficiency Virus (HIV) usually present digestive abnormalities and the esophagus is a common target of structural lesions. Infections are the most frequent cause of esophageal lesions in these patients. Several agents were already implied in this process. Viral infections are one of the main causes of such lesions and cytomegalovirus (CMV) and herpes simplex virus (HSV) were the most involved agents. Many ulcerated lesions persist without etiologic diagnosis even after exhaustive investigation, being denominated idiopathic or aphthous ulcers. The usual diagnostic methods are difficult and have low sensitivity. Thus, the main objective of our study was to evaluate the role of the polimerase chain reaction (PCR) method in the diagnosis of these lesions. During the period of October of 1996 to October of 1997, 79 HIV-positive patients were studied. They were submitted to upper digestive endoscopies, which were indicated on clinical basis. These patients were submitted to 89 upper digestive endoscopies, being obtained 96 biopsies, which were stored in liquid nitrogen or in a 70oC freezer. DNA was extracted using a method based on hypotonic lyses, proteinase K digestion, extraction with phenol-chloroform and precipitation in ethanol. A fixed amount was used for amplification in thermal cycler, using specific primers for CMV, herpesvirus, human papillomavirus (HPV), HIV, Haemophilus ducreyi, Treponema pallidum, Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium intracellulare. The final products were submitted to an electrophoresis in agarose gel and stained with ethidium bromide. The endoscopies did not reveal esophageal alterations in 26 exams(29,2%). The abnormalities observed were esophageal candidiasis in 33 exams (37,1%), ulcers in 22 (24,7%); esophagitis in 10 (11,2%) and lugol-negative areas in 9 (10,1%). The PCR was positive to CMV in 19 samples (19,8%), for Herpes in 4 (4,2%), for HPV in 17 (17,7%), for HIV in 37 (38,5%) and for the H. ducreyi in 3 (3,1%). No sample was positive for T. pallidum or micobacterium. In the study of the esophageal ulcers by PCR, CMV was detected in 9 samples (31%), Herpes in 3 (10,3%), HPV in 6 (20,7%), HIV in 19 (65,5%), H. ducreyi in 2 (6,9%) and any agent was detected in 8 samples (36,4%). CMV was frequently detected in esophageal ulcers, being difficult to differentiate between active and latent infections. The HIV had an elevated incidence in ulcer biopsies, which may suggest a possible etiologic role of this virus in such lesions. HPV was the third more frequent agent, but it was not possible to attribute the esophageal lesions to that virus. In conclusion, this study suggests that the PCR can be an useful method in the investigation of esophageal lesions in HIV infected patients.

(Re)construção de si: significados discursivos em torno do viver com HIV/aids / Re)self-construction: discursive meanings relating to living with HIV/AIDS

Oliveira, Cassiara Boeno Borges de 01 September 2017 (has links)
Este estudo objetivou compreender os significados de viver com o vírus da imunodeficiência adquirida/síndrome da imunodeficiência adquirida (HIV/aids) sob a perspectiva de pessoas vivendo com HIV (PVH), acompanhadas no Serviço de Atendimento Especializado em doenças infectocontagiosas (SAE) de São José do Rio Preto, São Paulo. Estudo com abordagem qualitativa, edificado no referencial teórico-metodológico da Análise de Discurso de matriz francesa. A população de estudo foi constituída por 11 sujeitos, os quais foram admitidos no SAE no ano 2000 e estavam em seguimento clínico ambulatorial no referido serviço em 2015. A geração de dados foi realizada entre os meses de maio e agosto de 2015. Aplicou-se a técnica de entrevista semidirigida norteada por roteiro de entrevista e utilizou-se, ainda, formulário de coleta de dados que considerou dados secundários (prontuário individual) e os relatos dos sujeitos. As entrevistas foram áudio-gravadas, transcritas na íntegra e armazenadas no software Atlas ti 7.0. Os gestos interpretativos possibilitaram a elaboração de dois blocos discursivos (BD): Sentidos de incorporação e (re)produção do discurso biomédico; e Da normalização à resistência: processos de experienciar o HIV/aids em cronicidade. No primeiro BD, os sujeitos adoecidos incorporaram o discurso biomédico, pautando suas experiências no cientificismo e na patologia. Com efeito, reproduziram o discurso dominante reverberando sentidos de seguimento ininterrupto da terapêutica medicamentosa, bem como de práticas e de comportamentos legitimados como salutares (alimentação saudável, higiene pessoal). No segundo BD, foram analisados os sentidos de normalização discursiva do HIV/aids, de modo que os sujeitos relacionaram as experiências de adoecimento às atividades do cotidiano que, sobretudo, deveriam minimizar exposição a situações de risco à saúde. Observou-se, porém, que tais sentidos de normalização estão envoltos em contextos fragilizadores, tais como o preconceito, o estigma e a discriminação ante ao HIV. Aspectos que pareceram estar na base de um discurso de resistência dos sujeitos adoecidos que, por sua vez, pareceu justificar momentos/períodos de interrupção do tratamento medicamentoso. Concluiu-se que o cuidado às PVH em cronicidade requer, entre outros, a constituição de reflexões (outras) que favoreçam uma relação dialógica proximal entre os profissionais de saúde e os sujeitos adoecidos. De tal sorte que se compreenda a dinamicidade de uma condição de adoecimento em constante devir, balizada pelo modo de ser e de estar de cada sujeito em seu meio / The goal of this study was to understand the meanings of living with the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) by the perspective of people living with HIV (PLH), assisted by the Specialized Service of infectious diseases (SS), São José do Rio Preto, São Paulo. Study through a qualitative approach, based on the theoretical-methodological referential of french Discourse Analysis framework. The study population consisted of 11 subjects, who were admitted to the SS in the year 2000 and were in an outpatient clinical follow-up in the same medical facility in 2015. Data were generated between May and August 2015. The semi-guided interview technique was applied guided by interview script. In addition, data collection form was used which considered secondary data (individual records) and the subjects\' reports. The interviews were audio-recorded, transcribed in full and stored in the software Atlas ti 7.0. The interpretative gestures allowed the elaboration of two discursive blocks (DB): Sense of incorporation and (re)production of the biomedical discourse; and From normalization to resistance: processes of experiencing HIV/AIDS in chronicity. In the first DB, the sick individuals incorporated the biomedical discourse, guiding their experiences in scientism and pathology. In fact, they reproduced the dominant discourse reverberating meanings of uninterrupted follow-up of drug therapy, as well as practices and behaviors legitimized as healthy (healthy eating, personal hygiene). In the second DB, the meanings of discursive normalization of HIV/AIDS were analyzed, so that the subjects related the experiences of illness to daily activities that, above all, should minimize exposure to health risk situations. It has been observed, however, that such meanings of normalization are embedded in fragilizing contexts, such as prejudice, stigma and discrimination against HIV. Aspects that seemed to be the basis of the sick subjects\' resistance discourse, which, in turn, seemed to justify moments/periods of interruption of drug treatment. It was concluded that care for chronical PLH requires, among other things, the constitution of reflections (others) that favor a proximal dialogical relationship between health professionals and those who are ill. So that the dynamicity of a condition of illness in constant becoming can be understood, distinguished by the way of being and being of each subject in its environment

Acessibilidade dos pacientes com a Síndrone da Imunodeficência Adquirida SIDA/AIDS em estabelecimentos odontológicos na Cidade de São Paulo / Dental clinical accessibility among patients with acquired immunodeficiency syndrome SIDA/AIDS in the city of São Paulo

Araujo, Sheila Soares de 14 December 2009 (has links)
O paciente portador de necessidades especiais pode ser descrito como aquele indivíduo que não se adapta de maneira física, intelectual ou emocional aos parâmetros normais, considerando os padrões de crescimento, desenvolvimento mental e controle emocional, além dos relacionados à conservação da saúde. A Organização Mundial de Saúde (OMS) estima que a prevalência das deficiências no mundo seja de uma pessoa a cada dez e mais de dois terços não recebe nenhum tipo de assistência odontológica. O objetivo do estudo foi verificar a percepção dos profissionais odontólogos sobre a acessibilidade do paciente com Síndrome da Imunodeficiência Adquirida (SIDA/AIDS) em estabelecimentos odontológicos na cidade de São Paulo e comparar com um grupo controle, representados por pacientes com Diabetes Mellitus. A informação para o estudo foi baseada em conversações telefônicas com cirurgiões-dentistas, onde foi realizada uma entrevista semi-estruturada. A análise de conteúdo das entrevistas foi executada segundo método de Lefèvre e Lefèvre (2000) e foi realizada destacando-se a idéia central. Do total de entrevistados, 55,14% eram do gênero feminino e 53,27% trabalhavam em consultório particular. Em relação à acessibilidade, 96,26% já tinham tratado de pacientes com Diabetes, 55,14% com SIDA/AIDS. Concluiu-se que a principal dificuldade para tratar pacientes com diabetes é a prática clínica, principalmente relacionada com problemas de coagulação. Entre os pacientes com SIDA/AIDS embora tenham sido citadas dificuldades clínicas, pôde ser verificado que a maior dificuldade ainda é o preconceito contra eles. / The patient who has special needs can be described as the individual that can´t adapt himself to normal physical, intellectual or emotional parameters, considering the growing patterns, mental development and emotional stability, in addition to those related to the health maintenance. The World Health Organization (WHO) estimates that the deficiencies prevalence is about one in ten individuals allover the world and more than two thirds don´t have any dental assistance. The objective of the study was to verify the dental professional perception with relation to the accessibility among patients with Acquired Immunodeficiency Syndrome (SIDA/AIDS) in clinical settings in the city of São Paulo, and to compare this perception with a control group, patients with Diabetes Mellitus. The study information was based on telephone conversations with Dentistis. A semi-structured interview was prepared. Content analysis was performed as per Lefèvre and Lefèvre (2000) with the relief of the central ideas. Among the participants, 55.14% were female and 53.27% worked in private settings. Regarding the accessibility, 96.26% had already treated patients with Diabetes, 55.14% with SIDA/AIDS. It was concluded that the main difficulty to treat diabetes patients is the clinical practice, mainly with problems related to blood coagulation. Among SIDA/AIDS patients, even though it had been listed clinical difficulties, it could be verified that the main difficulty is still prejudice amongst them.
