28例HIV感染儿童口腔损害发病情况初步分析

目的:初步了解云南地区部分HIV感染儿童的口腔健康状况。方法:采用横断面研究设计,对昆明市第三医院感染科28例(女16例,男12例)HIV感染儿童进行口腔检查,记录软组织损害、牙齿龋坏情况,通过问卷询问家长获得儿童人口流行病学信息、口腔卫生行为、饮食习惯和求医行为,通过治疗记录获得最近的CD4+T细胞计数,病毒载量、全身情况、用药等信息。结果:50%的儿童有一至多种口腔损害,口腔念珠菌病(OC)是HIV感染儿童最常发生的口腔损害(10例,占35.7%),其中以假膜型为主要表现形式(占28.6%),其次为牙龈炎(4例,占14.3%)。发生口腔念珠菌病儿童中有70%的CD4计数<200 cells/μL。约一半儿童尚未接受高效抗逆转录病毒治疗。结论:假膜型口腔念珠菌病是HIV感染儿童最常见的口腔病损,可能与CD4水平偏低和病毒载量偏高有关。     

Oral manifestations of primary immunological diseases

BACKGROUND: Primary immunodeficiencies have many oral manifestations. The clinical presentation of these diseases demonstrates the roles of different immune cells for the maintenance of oral health. METHODS: The authors reviewed selected literature describing systemic and oral manifestations of the primary immunodeficiencies published between 1966 and 1999. RESULTS: The authors found that oral candidiasis and herpetic infections are seen frequently in patients with T-cell deficiencies, while patients with B-cell deficiencies are most susceptible to bacterial infections. Periodontitis and oral candidiasis are found in some, but not all, phagocyte deficiencies. CONCLUSIONS: These findings demonstrate that T cells, B cells and phagocytes all have roles in oral immunity. CLINICAL IMPLICATIONS: Acquired conditions that affect the immune system such as diabetes, alcoholism and acquired immunodeficiency syndrome, as well as certain medications, will affect oral defense mechanisms. The effects that acquired immunodeficiencies will have on oral health can be predicted from the oral manifestations of primary immunodeficiencies.     

Sensitivity, specificity, and positive predictive value of oral opportunistic infections in adults with HIV/AIDS as markers of immune suppression and viral burden

OBJECTIVES: The purpose of this study was to assess the use of human immunodeficiency virus (HIV)-related oral opportunistic infections as markers of immune suppression and viral burden in adults with HIV/acquired immunodeficiency syndrome (AIDS). METHODS: The population consisted of a single institution observational cohort involving 606 patients with HIV/AIDS with CD4 count data and 277 with plasma viral load measurements examined between 1995 and 1999 for the presence of oral manifestations of HIV. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value is reported for the association of specific oral lesions and lesion sets with CD4 counts <200 cells/mm(3) and with plasma HIV RNA >/=20,000 copies/mL. RESULTS: Lesions with moderate-to-high PPVs for CD4 <200 cells/mm(3) were as follows: Kaposi's sarcoma (100%; P =.035), pseudomembranous candidiasis (82. 2%; P <.001), linear gingival erythema (70.0%; P =.015), hairy leukoplakia (66.3%; P <.001), angular cheilitis (60.0%; P =.128), and erythematous candidiasis (58.3%; P =.061). Necrotizing ulcerative periodontal diseases, HIV salivary gland disease, oral ulcers, and oral warts had PPVs below 50%. Concurrent infection with candidiasis and hairy leukoplakia had the highest PPV of 89.3%; P <. 001. PPVs for HIV RNA >/=20,000 copies/mL ranged from 27.3% to 100%, with significant association only for pseudomembranous candidiasis. CONCLUSIONS: Specific common oral lesions are strongly associated with immune suppression, as measured by CD4 cell counts, and are modestly associated with high viral burden, thus serving as potential clinical markers of HIV viremia and the consequent destruction of the immune system with progressive HIV disease.     

Differences in risk factors among clinical types of oral candidiasis in the Women's Interagency HIV Study.

OBJECTIVES: The purpose of this study was to determine the prevalence and concurrence/associations of oral candidiasis types and multiple risk factors in women. STUDY DESIGN: A cross-sectional analysis of baseline data for 577 human immunodeficiency virus (HIV)-seropositive and 152 HIV-seronegative women from the Women's Interagency HIV Study was conducted. Pseudomembranous candidiasis (PC) and erythematous (EC) candidiasis, angular cheilitis (AC), and denture stomatitis (DS) were studied, and bivariate and multivariate regression analyses were performed. RESULTS: Prevalences were 8% for PC, 7% for EC, 18% for DS, and 3% for AC; all except AC usually occurred alone. HIV seropositivity was associated with PC, EC, and DS, but not AC. Among HIV-seropositive women, low CD4 cell counts were associated with PC, but not with EC or DS. Heroin/methadone use was associated with PC and EC; salivary hypofunction was associated with PC; high viral load was associated with EC, and poor oral hygiene, with EC and DS. CONCLUSIONS: Risk factors varied among candidiasis types, suggesting differences in pathogenic mechanisms and usefulness as markers of HIV infection/progression.     

Oral lesions and conditions associated with human immunodeficiency virus infection in 300 south Indian patients

BACKGROUND: Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) is a major health problem in India. The National AIDS Control Organisation (NACO) of India reports a seropositivity of 25.03 per thousand for the whole country, as of October 1999. In spite of this high prevalence there are very few reports of oral lesions and conditions in Indian HIV/AIDS patients, which are important in early diagnosis and management of these patients. OBJECTIVE AND SETTING: The present report describes the oral lesions in 300 HIV positive symptomatic patients presenting to us at RAGAS-YRG CARE, a non-governmental organisation in Chennai, South India, over a period of 9 months in 1998. METHOD: Lesions were diagnosed on clinical appearance using international criteria. RESULTS: Of the 300 patients 89% had acquired the infection through heterosexual contact. There were 205 males and 95 females, aged from 7 months to 72 years. Forty-seven percent of the patients were in the age group 21-30 years. CD4 counts were ascertained for 105 patients, 64 (62%) had CD4 counts < or = 200. A total of 217 (72%) of the 300 patients had some oral lesion when examined. Gingivitis (47%) and pseudomembranous candidiasis (33%) were the most common oral lesions. The other oral lesions seen were oral mucosal pigmentation (23%), erythematous candidiasis (14%), periodontitis (9%), angular cheilitis (8%), oral ulcers (3%), oral hairy leukoplakia (3%), hyperplastic candidiasis (1%), oral submucous fibrosis (2%) and one case of leukoplakia. CONCLUSIONS: Oral lesions occur commonly in HIV infection. A comprehensive oral examination may not only suggest HIV disease but may also be useful in monitoring the disease progression. This is a cost-effective procedure, which may be useful in screening large populations in developing countries like India.     

HIV/AIDS患者口腔病损的临床特点分析

目的了解艾滋病相关口腔病损的临床特点及其与CD4计数和高效抗逆转病毒治疗（highly active antiretroviral therapy,HAART）之间的关系。方法回顾性研究2012~2013年在我院收治的109例HIV/AIDS患者的临床资料,包括流行病史、艾滋病临床阶段、口腔表现、全身症状、CD4计数、治疗及预后等,通过Excel建立数据库,进行统计学分析。结果 109例HIV/AIDS患者中48例出现艾滋病相关口腔病损,其中口腔念珠菌感染48例（44.03%）,以假膜型为主,口腔深大溃疡5例（4.59%）,卡波西肉瘤和淋巴瘤各2例（1.83%）,牙龈线型红斑、口腔单纯疱疹和口腔疣各1例（0.92%）。CD4〈200个/ul组口腔病损的发生率高于CD4≧200个/ul（P〈0.01）,HAART治疗组口腔病损的发生率低于未治疗组（P〈0.01）,差异有显著性。结论口腔是HIV/AIDS患者最常见的机会性感染部位。口腔病损中以假膜型口腔念珠菌病最常见,其次是口腔深大溃疡、口腔恶性肿瘤。卡波西肉瘤和淋巴瘤死亡率高,早期口腔表现易与淋巴结炎、牙龈炎混淆,应尽早进行病理检查,早期诊断。HIV/AIDS患者口腔病损的发生与CD4计数减少有关,HAART治疗能显著降低口腔病损的发生。     

Oral lesions as indicators of HIV infection among routine dental patients in Lagos, Nigeria

OBJECTIVES: To document the incidental oral lesions of human immunodeficiency virus (HIV) infection, the pattern and frequency of the lesions based on clinical presentation and oral manifestations in routine dental patients who tested positive in Nigeria. SUBJECTS AND METHODS: The study was conducted at the Oral Diagnosis/Oral Medicine clinic of the Lagos University Teaching Hospital, Lagos, Nigeria between May 2002 and April 2003. During this period, all patients with oral lesions suggestive of HIV/acquired immunodeficiency syndrome (AIDS) as described in the EEC-WHO Classification and diagnostic criteria of oral lesions of HIV were counseled and offered voluntary HIV testing. All the 35 patients who consented and tested positive were included in this study. RESULTS: Of a total of 700 patients 53 patients with oral lesions suggestive of HIV/AIDS were seen, thirty-eight (72%) consented to HIV screening, 15 patients (28%) refused. Thirty-five patients (92%), mean age 36 +/- 13 years were confirmed positive for HIV. Oral candidiasis was the commonest lesion seen (43%) the second common being Herpes zoster (23%). Other lesions seen included erythema multiforme in two (6%), facial palsy in two (6%) and oral hairy leukoplakia in one (3%). CONCLUSION: An oral mucosal lesion may be the presenting lesion of HIV/AIDS in routine patients attending the dental clinic. Oral health care workers should practice optimal infection control based on the Centers for Disease Control 'Standard Precautions' guidelines on infection control for all patients to minimize occupational transmission of HIV.     

Oral lesions among persons with HIV disease with and without highly active antiretroviral therapy in southern India

BACKGROUND: The advent of highly active antiretroviral therapy (HAART) has changed the scenario of human immunodeficiency virus (HIV) infection. HIV patients in India have now access to generic HAART and this is the first report describing oral lesions in patients on HAART from our country. METHODS: Oral lesions were studied in HIV seropositive patients (n = 50 on HAART and n = 50 not on HAART) attending a tertiary HIV referral care centre in India and patients on HAART were followed up. RESULTS: There was a difference in the occurrence of oral candidiasis (OC) between HAART and non-HAART participants (8%, 24%; P < 0.05). Pseudomembranous candidiasis was 4% and 18% in HAART and non-HAART groups respectively (P < 0.05). In patients with CD4 count 200, pigmentation was 43.8% in the HAART group and 14.8% in the non-HAART group (P < 0.05). CONCLUSION: The prevalence of OC in patients who had access to HAART was less when compared with those who did not have access to HAART.     

Treatment of refractory oral candidiasis with fluconazole. A case report

We describe a patient with the acquired immunodeficiency syndrome who had persistent oral esophageal pseudomembranous candidiasis clinically refractory to nystatin, clotrimazole, and ketoconazole. In vitro resistance to clotrimazole was demonstrated as well. The patient received temporary relief with intravenous amphotericin B therapy, but this was associated with serious adverse effects, including transfusion-requiring anemia, azotemia, and severe thrombophlebitis. Despite two courses of intravenous amphotericin B therapy, the patient's highly symptomatic, recurrent oral and esophageal candidiasis continued. The patient was then treated with fluconazole and obtained immediate relief without associated adverse effects.     

Oral manifestations of HIV infection and their correlation with CD4 count

Human Immunodeficiency Virus (HIV)-related oral lesions can be used as markers of the immune status. The present cross-sectional study was conducted to identify the oral manifestations in HIV-infected individuals and their association with reduced Cluster of Differentiation 4 (CD4) count. The study population included known HIV-positive patients. A detailed case history of 399 HIV-positive patients was obtained and general examination was carried out. Diagnosis of oral lesions was done based on presumptive criteria of EEC Clearinghouse, 1993. The CD4 count was determined in 369 patients and correlated with oral manifestations. The prevalence of oral lesions was found to be 76.70% (n = 306). Oral candidiasis (157 (39.3%)) was the most common oral lesion associated with HIV infection. Amongst various forms of oral candidiasis, erythematous candidiasis (122 (39.3%)) outnumbered the other forms. The mean CD4 count of patients with oral lesions (207 cells/mm(3)) was less than in patients without oral lesions (291 cells/mm(3)) (P = 0.002). Oral candidiasis was found to be significantly correlated to a reduced CD4 cell count below 200 cells/mm(3) (P = 0.000; Odds ratio = 3.1; 95% Confidence interval 1.9-4.9) with good sensitivity, best specificity and positive predictive value. Oral manifestations may be used as an alternative to CD4 count at field-based settings to diagnose the immune compromised status of HIV-infected individuals.     

Aetiological factors for oral manifestations of HIV

OBJECTIVES: Describe the oral diseases in HIV-infected individuals in London, UK and identify social and medical factors related to the presence of specific oral diseases.
DESIGN: Cross-sectional analytic study.
SETTING: Dental clinics.
SUBJECTS: Consecutive sample of 456 patients with HIV infection.
METHODS: Social and medical history and clinical examinations. Univariate and logistic regression analysis.
OUTCOMES: Presence of HIV-associated oral disease.
RESULTS: 80% of patients with AIDS and 50% of patients with HIV had a specific oral disease. The most common diseases were hairy leukoplakia (30%), erythematous candidiasis (24%), pseudomembranous candidiasis (14%), angular chielitis (6%), necrotising periodontal disease (8%) and non-recurrent ulceration (6%).
CONCLUSIONS: The presence of erythematous candidiasis was not related to advanced HIV disease. Pseudomembranous candidiasis, hairy leukoplakia and mucosal ulceration were significantly associated with advanced HIV disease. Smoking was also identified as a strong aetiological factor in oral diseases. Longitudinal studies are required to further explore the prognostic significance of oral diseases in HIV infection.     

Oral lesions associated with HIV/AIDS in HIV‐seropositive patients attending a counselling and treatment centre in Dar es Salaam

Objective: To assess the prevalences and patterns of oral lesions occurring in human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). Methods: A cross‐sectional study was conducted among 200 people living with HIV/AIDS (PlwHA) who regularly attended a counselling and treatment centre in Dar es Salaam, Tanzania. A questionnaire‐guided interview and clinical oral assessment were used. Strict confidentiality and adherence to ethical codes were observed. Results: The mean age of participants was 38.91 years (standard deviation: 10.424; mode: 35 years; median: 37.0 years; range: 15–76 years). Most participants (58.5%) were aware of predispositions towards the occurrence of oral lesions such as oral candidiasis (60.0%) in HIV/AIDS and most of these (72.0%) were aware that the lesions are treatable. Some participants reported occurrences of oral thrush (22.5%) and lip ulcerations (28.5%), although only 47.0% of these had sought medical advice. Examinations revealed that 29.0% of participants had at least one oral lesion associated with HIV/AIDS. Prevalences of the various types of lesion were: 11.5% for herpes simplex; 7.5% for oral candidiasis; 4.0% for oral hairy leukoplakia; 3.5% for Kaposi’s sarcoma; 1.5% for dry mouth; 0.5% for angular cheilitis, and 0.5% for acute necrotising ulcerative gingivitis. Herpes simplex and Kaposi’s sarcoma were more frequently observed in males (56.5% and 71.4%, respectively), whereas oral candidiasis and dry mouth were observed more often in females (86.7% and 66.7%, respectively) (χ² = 16.692, P = 0.016). Conclusions: Prevalences of oral lesions associated with HIV/AIDS in PlwHA and using antiretroviral therapy are persistent, of moderate intensity and vary according to individual immune status. These patients’ level of awareness about oral lesions was satisfactory, but formal medicodental lines of management were not prioritised. Contemporary protocol for the management of oral lesions should be understood and disseminated to the general public by dentists.     

Oral manifestations related to immunosuppression degree in HIV-positive children.

Oral manifestations often found in HIV-infected children are frequently the first clinical sign of the infection. This article aims to report the prevalence of oral manifestations in soft tissues and their relationship with the degree of immunosuppression in 80 HIV-infected patients (average age 6.30 +/- 3.32 years old) at the IPPMG-UFRJ. Thirty children (38%) presented some type of oral lesion and the percentage of CD4 was lower than that found in lesion-free children (p < 0.05); 22.5% presented candidiasis, 17.5% gingivitis, 8.8% enlargement of parotids, 1.3% herpes simplex and 1.3% hairy leukoplakia. Of the 30 children with lesions, 70% showed severe immunosuppression, 23.3% moderate immunosuppression and in only 6.7% was immunosuppression absent. Oral manifestations were directly related to the degree of immunosuppression and such lesions can be considered as indicators of the progression of the HIV infection in children.     

Oral manifestations associated with human immunodeficiency virus infection in a Spanish population

A study was made of the oral manifestations in 396 patients with human immunodeficiency virus (HIV) infection. The following risk groups were established: intravenous drug users (79.5%), homosexuals (7.8%), homosexual intravenous drug users (3.3%). heterosexuals (8.1%) and hemophiliacs/transfusion patients (1.3%). The oral lesions, in decreasing order of frequency, were: periodontal disease (78.28%). candidiasis (65.65%). hairy leukoplakia (16.16%). herpes simplex virus lesions (5.30%), Kaposi's sarcoma (2.27%), recurrent aphthous ulceration (RAS) (1.01%), lichen planus (0.5%), non-Hodgkin's lymphoma (0.25%). tuberculous lesion of the tongue (0.25%) and ulcerations of uncertain etiology (0.25%). Attention is drawn to the greater predominance of these lesions in patients with CD4 values of less than 200/mm³, compared with those who have higher lymphocyte counts.     

Oral manifestations in 45 HIV-positive children from Northern Thailand

Forty-five Northern Thai children with HIV infection or AIDS were examined for oral manifestations. Of these children, 51.1% (n=23) were asymptomatic (category N), 48.9% were mildly, moderately or severely symptomatic (category A, B, C) and 48.9% (n=22) revealed oral lesions. Eleven patients (24.4%) showed one oral lesion, eight (17.8%) had two and three (6.6%) had three oral lesions. Erythematous candidiasis was the most common lesion (17.8%). Oral hairy leukoplakia was seen in 6.7% (n=3). Geographic tongue, not usually considered to be associated with HIV infection, was seen in 6.7% (n=3). Only 15 patients (33.3%) received antiretroviral therapy (ART). Comparison of patients with or without ART did not show differences in the prevalence of oral lesions. More studies in Thai HIV-infected children are needed to reveal the prevalence of oral manifestations, as well as for the predictive value of the most common or specific oral manifestations.     

Oro-facial manifestations in paediatric HIV: a comparative study of institutionalized and hospital outpatients

The aim of the study was to compare dental caries status and the number and type of oral mucosal lesions in HIV positive children from a hospital outpatient department and an institutionalized setting. Oral examinations were performed using presumptive diagnostic criteria. The Fisher's Exact and the Mann-Whitney tests were used for statistical comparison of the two study groups. A total of 169 children were examined of whom 42% were institutionalized and 58% hospital outpatients. One institutionalized child presented with Noma. Twenty-one percent of the institutionalized population presented with molluscum contagiosum, while none of the hospital outpatients presented with this condition. Significantly more intraoral mucosal lesions were observed in the hospital compared with the institutionalized group. The most frequently encountered oral lesion was candidiasis. Pseudomembranous candidiasis was the most common type. Twice as many intraoral ulcers were recorded in the institutionalized group. Thirty-nine percent of the hospitalized patients had multiple lesions compared with 28% in the institutionalized group. Almost three quarters of both populations were caries-free. The mean DMFT was considerably higher in the hospital population. For both the permanent and primary teeth, the decayed component (D/d) made up the major part of the DMFT/dmft, followed by the missing (M/m) component. No fillings were recorded in either the primary or permanent teeth for both groups. Oral lesions are common in HIV populations and were seen in both the hospital and institutionalized groups, at high prevalence levels (63 and 45%). HIV infected children should be considered high risk for caries because of the use of chronic medications, and to receive appropriate care in terms of both treatment and services.     

Oral soft tissue manifestations in HIV-positive vs. HIV-negative children from an inner city population: a two-year observational study

PURPOSE: Data accrued after two years of longitudinal observation of oral soft tissue lesions in a cohort of HIV-infected children and comparisons to a group of uninfected controls is presented. SUBJECTS AND METHODS: One hundred and four HIV-positive subjects were enrolled from an inner city pediatric HIV clinic and HIV-negative household peers served as control. Oral exams were performed at six-month intervals while laboratory data of interest were obtained from the children's medical records. RESULTS: HIV-positive children had significantly more oral soft tissue lesions than their HIV-negative peers. In particular, the prevalence of candidiasis, linear gingival erythema and median rhomboid glossitis were high. However, oral lesions were not good predictors of mortality and only candidiasis was associated with a low CD4 count. CONCLUSIONS: Oral soft tissue lesions were common among HIV-positive children. While candidiasis was correlated with advanced disease, oral lesions were not good predictors of mortality.     

Oral manifestations in HIV-positive adults from Northern Thailand

Eighty-seven HIV-infected patients in a provincial hospital in Northern Thailand were examined for oral manifestations of HIV disease and AIDS. The median age was 31.3 years. Seventy-four of the patients were women, 13 were men. 96.6% had a history of heterosexual transmission. Sixty-one patients were CDC-category A, 20 were category B and 6 were category C (AIDS). Thirty-eight percent of the patients revealed oral lesions; 23% had one oral lesion and 13.8% had two oral lesions. Common lesions were oral candidiasis (10.3% pseudomembranous candidiasis, 6.9% erythematous candidiasis and 3.4% both forms), oral hairy leukoplakia (11.5%) and exfoliative cheilitis (6.9%). Gingival linear erythema was seen in 8% of the patients; periodontal lesions and necrotising ulcerative gingivitis were not observed. Men were more commonly affected by oral manifestations than women (P < 0.004). The spectrum of oral lesions is comparable to other studies from the region, although most of these reported more men than women. Also, the degree of immunosuppression was more marked (AIDS).     

Oral manifestations of disseminated Cryptococcus neoformans in a patient with acquired immunodeficiency syndrome

A palatal lesion was the initial manifestation of disseminated cryptococcosis in a patient with acquired immunodeficiency syndrome (AIDS). The diagnosis was initially verified with cytologic smears in situ and later confirmed with pathologic findings from an excisional biopsy specimen. As cryptococcosis is one of the major opportunistic infections in persons with AIDS, an increased incidence of oral manifestations of cryptococcosis can be expected.
