目的探讨艾滋病病毒(HIV)感染者/艾滋病(AIDS)病人(简称HIV/AIDS病人)合并血流感染者病原菌的分布特点,为临床诊疗提供参考。方法回顾性分析76例血培养阳性的HIV/AIDS病人的临床资料,并与同期普通病人的资料进行比较。结果研究期间,共收集血培养阳性菌株1263株,其中79株分离自HIV/AIDS病人的血培养标本,1184株分离自普通病人的血培养标本。HIV/AIDS病人血培养病原菌主要以分枝杆菌最常见(22.8%),其次是马尔尼菲青霉菌(21.5%)和新型隐球菌(11.4%);普通病人血培养病原菌则以大肠埃希菌(23.1%)、肺炎克雷伯菌(13.3%)和屎肠球菌(6.6%)最常见。两组病人真菌感染的比例有显著差异(P0.001),且真菌的菌种分布明显不同。结论 HIV/AIDS病人易发生由分枝杆菌和马尼菲青霉菌等引起的血流感染,临床上应加强对HIV/AIDS病人血流感染病原菌的监测,积极防治血流感染的发生。  相似文献

农村社区HIV感染者/AIDS病人分级管理模式探讨   总被引:3,自引:0,他引:3  
加强对艾滋病病毒(HIV)感染者和艾滋病(AIDS)病人的管理,是控制HIV进一步传播的重要措施。我国80%的HIV感染者分布在农村,对HIV感染者/AIDS病人管理主要在社区进行。目前已有地区在探索对HIV感染者/AIDS病人的管理方法,并提出一些好的建议。上蔡县20世纪90年代中期部分农民因不规范有偿供血而感染HIV,且造成二三代传播。截止2005年底,HIV感染者和AIDS病人达6千多人。  相似文献

菏泽市HIV感染者生存现状和需求的调查   总被引:2,自引:1,他引:1  
菏泽市自2000年12月发现首例艾滋病病毒(HIV)感染者以来,随着近几年艾滋病监测力度的不断加大,越来越多的HIV感染者和艾滋病(AIDS)病人被检出。由于这部分感染人群以青壮年为主,他们在面临不断恶化的健康状况时,还将陷入因劳动力迅速丧失而导致的家庭经济困难。同时,普遍存在的对HIV感染者/AIDS患者的歧视,使他们的生存环境日益恶化。因此,关注HIV感染者/AIDS患者的生存环境和生活质量,  相似文献

This study employed culture and polymerase chain reaction (PCR) to examine the prevalence of Ureaplasma urealyticum, Mycoplasma hominis, Mycoplasma genitalium, Mycoplasma fermentans, Mycoplasma penetrans and Mycoplasma pirum in 210 HIV/AIDS patients, 455 sexually transmitted infection (STI) clinic attendees and 245 healthy volunteers from first-void urine specimens for men and endocervical swabs for women. U. urealyticum and M. hominis were detected in 107 (51.0%) and 69 (32.9%) patients in the HIV/AIDS group. At least one of the other four organisms was detected in 34 (16.2%) HIV/AIDS patients, 29 (6.4%) STI clinic attendees and six (2.5%) healthy volunteers. This study showed that U. urealyticum, M. hominis and M. fermentans were significantly more prevalent in HIV/AIDS patients, as were other mycoplasmas. Our results suggest a possible role for co-infection.  相似文献

The magnitude of intestinal parasitic infection in human immunodeficiency virus (HIV) /AIDS patients requires careful consideration in the developing world. However, there have been very few studies addressing this issue in Ethiopia. This study was conducted to determine the prevalence of intestinal parasitic infection in HIV/AIDS patients at Jimma Hospital, Southwest Ethiopia, between January and February 2002. Stool specimens from HIV/AIDS patients and control groups were screened for intestinal parasitic infections using direct and formalin-ether sedimentation concentration methods. Out of 78 HIV/AIDS patients, 52.6% (41/78), and out of 26 HIV-negative individuals, 42.3% (11/26), were infected with one or more types of intestinal protozoa and/or helminthes. The parasites detected among HIV/AIDS patients included Ascaris lumbricoides (30.8%), Blastocystis spp. (14.1%), Entamoeba histolytica (10.3%), Trichuris trichiura (6.4%), Strongyloides stercoralis (5.1%), Giardia lamblia (3.8%), Schistosoma mansoni (2.5%), hookworm species (2.5%), and Taenia spp. (1.3%). Multiple infections were more common among HIV/AIDS patients. Blastocystis spp. were found to be significantly higher in HIV/AIDS patients than in controls (P < 0.05). The magnitude of intestinal parasitic infection was high both in HIV/AIDS patients and in controls. Routine examinations of stool samples for parasites would significantly benefit the HIV-infected and uninfected individuals by contributing to reduce morbidity.  相似文献

ObjectiveTo determine the magnitude of opportunistic and non-opportunistic intestinal parasitic infections among HIV/AIDS patients in Bahir Dar.MethodsCross-sectional study was conducted among HIV/AIDS patients attending Gambi higher clinic from April1-May 30, 2009. Convenient sampling technique was employed to identify the study subjects and hence a total of 248 subjects were included. A pre-tested structured questionnaire was used to collect socio-demographic data of patients. Stool samples were examined by direct saline, iodine wet mount, formol-ether sedimentation concentration and modified Ziehl-Neelsen staining technique.ResultsOut of 248 enrolled in the study, 171(69.0%) (90 males and 81 females) were infected with one or more intestinal parasites. The highest rate of intestinal parasites were observed among HIV/AIDS patients (80.3%, 151/188), and the infection rate of HIV negative individuals was 33.3% (20/60). Cryptosporidum parvum (43.6%), Isospora belli (15.5%) and Blastocystis hominis (10.5%) were opportunistic parasites that were found only in HIV/AIDS patients.ConclusionsOpportunistic parasite infections are common health problem among HIV/AIDS patients in the study area. Therefore, early detection and treatment of these parasites are important to improve the quality of life of HIV/AIDS patients.  相似文献

Sixty-four episodes of bacterial infection were identified over a 44-month period in 16 of 28 patients with the acquired immune deficiency syndrome (AIDS) and 14 of 31 patients with AIDS-related complex. Nineteen of the 30 infected patients were parenteral drug abusers, 10 were from Caribbean Islands and had no identified risk factor, and one was a homosexual male. Fourteen patients had 21 episodes of community-acquired pneumonia: Streptococcus pneumoniae (10), Haemophilus influenzae (three), other Haemophilus species (three), group B beta-hemolytic streptococci (one), Staphylococcus aureus (one), Branhamella catarrhalis (one), Legionella pneumophila (one), and Mycoplasma pneumoniae (one). Seven patients had eight episodes of nosocomial pneumonia caused by gram-negative bacilli. Twenty-five episodes of community-acquired bacteremia and nine episodes of nosocomial bacteremia were associated with specific sites of infection. Other infections included meningitis (two), urinary tract infection (one), and abscesses involving subcutaneous and deep tissues (12). Sixteen patients had recurrent infections; 11 of these had or eventually had AIDS. Community-acquired bacterial infections in patients with AIDS or AIDS-related complex are common and may be recurrent but have low fatality rates. In comparison, nosocomial bacterial infections occur primarily in patients with AIDS and have high fatality rates.  相似文献

In order to verify the occurrence of intestinal parasitic infections in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients, 100 HIV/AIDS patients (Group 1) and 85 clinically healthy individuals (Group 2) were submitted to coproparasitological examination. Intestinal parasites were detected in 27% of patients from Group 1 and in 17.6% from Group 2. In Group 1 the most frequent parasites were Strongyloides stercoralis (12%), with 2 cases of hyperinfection; Isospora belli, 7%; Cryptosporidium sp., 4%; with 1 asymptomatic case and hookworm, 4%. Of the infected patients from Group 1 who reported to be chronic alcoholics, 64.3% had strongyloidiasis. Only 6 of the 27 infected patients from Group 1 were on highly antiretroviral therapy (HAART). In Group 2 the most frequent parasites were S. stercoralis, 7.1%; hookworm, 7.1% and Giardia lamblia, 3.5%. In conclusion, diagnosing intestinal parasites in HIV/AIDS patients is necessary especially in those who report to be chronic alcoholics or are not on antiretroviral treatment.  相似文献

OBJECTIVE: To compare the clinical manifestations observed in AIDS patients infected with HIV2 and HIV1 infection. METHODS: The medical records of AIDS patients hospitalized between January 1986 and July 1997 at the Department of Infectious Diseases of Fann Hospital, Dakar, were reviewed. RESULTS: 599 hospitalizations (76%) were HIV1 seropositive patients, 137 (17%) were HIV2 seropositive patients and 54 (7%) were patients serologically dually reactive to HIV1 and HIV2. There was no significant difference in medium CD4 lymphocyte count between patients with HIV1 and HIV2 infection. Chronic diarrhoea and diarrhoea caused by bacterial infections were more frequently observed in HIV2-infected individuals. Oral candidiasis and chronic fever were more often noted in patients with HIV1 infection. Bacterial and cryptococcal meningitis was only observed among patients with HIV1 infection. CONCLUSIONS: Certain clinical differences were observed comparing AIDS patients with HIV1 and those with HIV2 infection. As there is no clear physiopathological explanation for these differences, additional studies with larger numbers of AIDS patients are needed to determine whether these differences are real.  相似文献
