RESUMEN

RATIONALE: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which quickly spread throughout the world, has been putting medical workers all over the world in difficulty because of the high number of cases combined with the lack of information about the disease. Although pediatric cases are rare, the group age under 12 months has been in general more susceptible to develop severe forms of the disease compared with the patients in the age interval of 1 to 18 years. PATIENT CONCERNS: Three newborns have been tested positive for SARS-CoV-2 infection. One of them presented bilateral decreased air entry, while the other 2 had no respiratory symptomatology. All 3 developed diaper erythema and oral candidiasis. DIAGNOSIS: For building up the report, newborns that were positive for coronavirus disease 2019 (COVID-19) infection were included in the case series. The chest X-ray of the symptomatic patient revealed a medium degree of hilar parenchymal infiltration and a slight infiltration of the visceral pleura. INTERVENTIONS: The patients were admitted in our isolated neonatology ward. All of them received antifungal treatment for the oral candidiasis and topic cream for diaper erythema. The symptomatic patient also received prophylactic antibiotherapy, human immunoglobulins, aminophylline, and parenteral nutrition. OUTCOMES: All 3 neonates were discharged after 2 consecutive negative tests for SARS-CoV-2. Patients 1 and 2 fully recovered, whereas the condition of patient 3 improved. LESSONS: Even if there are only a few reported cases of neonates infected with COVID-19 and most of them present mild manifestations, newborns need a more careful insight because of the nonspecific symptomatology.

RESUMEN

BACKGROUND: Mucocutaneous manifestations are one of the first clinical signs in patients infected with human immunodeficiency virus (HIV). To the best of our knowledge, there has been no previous study describing dermatologic manifestations in Mauritanians infected with HIV. The aim of the present study was to determine the profiles of mucocutaneous manifestations in relation to CD4 T cell count in HIV-positive Mauritanian patients. METHODS: A total of 86 adult patients aged > 18 years old attending the Ambulatory Treatment Center of the National Hospital of Nouakchott, Mauritania, with newly diagnosed HIV and who were not under antiretroviral treatment were included in the study in 2015. Dermatologic manifestations were documented before initiating antiretroviral treatment. RESULTS: Most of the included patients were in clinical stage 3 of the World Health Organization classification at initial diagnosis, with the mean CD4 T cell count (± SD) of 514 ± 319 cells/mm3 (range, 2-1328 cells/mm3 ), and 19 of 86 (22.1%) patients had CD4 T cell counts below 200 cells/mm3 . More than half (64%) of newly diagnosed HIV-infected patients had dermatoses, including the following: pruritic papular eruption (44.2%), seborrheic dermatitis (4.7%), Kaposi's sarcoma (3.5%), extensive xerosis cutis (2.3%), drug-induced skin reactions (1.2%), and various infectious dermatoses (dermatophyte infections [16.3%], oral candidiasis [11.6%], herpes zoster [8.1%], and scabies [2.3%]). A low CD4 T cell count (< 200 cells/mm3 ) was significantly correlated (P < 0.05) with the presence of following dermatoses: dermatophytosis, oral candidiasis, Kaposi's sarcoma, seborrheic dermatitis, and extensive xerosis cutis. CONCLUSION: Mucocutaneous lesions occur throughout the course of HIV infection, and dermatologic findings in Mauritanian HIV-positive patients are similar to those of patients in other countries. Early detection of skin disorders in some patients may help establish the diagnosis of HIV and management of HIV-associated diseases, limiting the cost of care in low-resource countries.

RESUMEN

The Oral HIV/AIDS Research Alliance (OHARA) was established in 2006 to provide the capacity to investigate the oral complications associated with HIV/AIDS within the ACTG infrastructure. Its goals were to explore the effects of potent antiretroviral therapy (ART) on the development of opportunistic infections, and variation and resistance of opportunistic pathogens in the context of immune suppression and long-term ART. The objectives of this talk, presented as part of a plenary session at the 7th World Workshop on Oral Health and Disease in AIDS, were to (i) provide an overview of OHARA's most recent research agenda, and how it evolved since OHARA's inception; (ii) describe OHARA's main accomplishments, including examples of research protocols completed and their key findings; and (iii) describe spin-off projects derived from OHARA, lessons learned, and future directions. OHARA has met its central goal and made key contributions to the field in several ways: (i) by developing/updating diagnostic criteria for oral disease endpoints commonly measured in OHARA protocols and in HIV/AIDS research in general and has creating standardized training modules, both for measuring these oral disease endpoints across clinical specialties, and for collecting oral fluid specimens; (ii) by implementing a total of nine protocols, six of which are completed. Three protocols involved domestic research sites, while three involved international research sites (in Africa, India, and South America); (iii) and by developing and validating a number of laboratory assays used in its protocols and in the field of oral HIV/AIDS research.

RESUMEN

The colonization by Candida species is one of the most important factors related to the development of oral candidiasis in HIV-infected individuals. The aim of the study was to evaluate and discuss the phospholipase, proteinase, DNAse and haemolytic activities of Candida albicans isolated from the oral cavity of HIV individuals with high efficiency antiretroviral therapy. Seventy-five isolates of C. albicans obtained from saliva samples of patients with HIV and 41 isolates from HIV-negative individuals were studied. Haemolytic activity was determined in Sabouraud dextrose agar plates containing 3% glucose and 7% sheep red cells. Culture medium containing DNA base-agar, egg yolk, and bovine albumin were used to determine DNase, phospholipase and proteinase activities, respectively. All isolates from the HIV patients group had haemolytic activity, 98% showed phospholipase activity, 92% were positive for proteinase and 32% DNAse activity. Regarding the group of indivídios HIV negative, all 41 isolates presented hemolytic activity, 90.2% showed phospholipase and proteinase activity and 12.2% were positive for DNAse. The phospholipase activity was more intense for the group of HIV positive individuals. DNase production was more frequently observed in the group of HIV-positive individuals. The percentage of isolates having DNAse activity was also significantly different between the groups of patients not using any antiretroviral therapy, those using transcriptase inhibitors and those using transcriptase inhibitor and protease inhibitor in combination.

RESUMEN

OBJECTIVE: Pediatric HIV is growing at an alarming rate in developing countries. Due to their compromised immune status, children infected with HIV are prone to a number of opportunistic infections. Oral manifestations are the first signs of the disease in many of them. To assess the oral mucosal status of Indian children with HIV, based on their CD4 cell counts. METHODOLOGY: Two hundred and twenty one HIV infected children aged 6-18 years from various HIV centers, were divided into three groups, based on their CD4 cell counts; Group 1: ≥500, Group 2: 201-499 and Group 3: ≤200 cells. The children in each group were further considered as 'prior to antiretroviral treatment (ART)' and 'on ART'. Oral mucosal examination was done based on presumptive criteria given by Ramos-Gomez for diagnosis of oro-facial lesions commonly associated with HIV infection in children. Data obtained was subjected to statistical analysis. RESULTS: Angular cheilitis and pseudomembranous candidiasis were the frequently seen oral lesions. Children with CD4 cell count ≥500 had significantly fewer oral lesions each. CONCLUSION: A high percentage of HIV-infected children were affected with oral mucosal lesions. There was a significant association between immune status and frequency of oral lesions.

RESUMEN

The objective of the study was to determine the prevalence of pediatric human immunodeficiency virus 1 (HIV-1) mucocutaneous manifestations in the era of highly active antiretroviral therapy (HAART). We conducted population-based, prospective, multicenter pediatric HIV-1 surveillance in 276 children with perinatally acquired HIV-1 from 1988 to 2009. Centers for Disease Control and Prevention (CDC)-defined HIV-1 related mucocutaneous conditions among the 276 children were: category A (n = 152), B (n = 60), and C (n = 1). Nearly half of the category A and B diagnoses (43.4% [66/152] and 35.0% [21/60], respectively) occurred in the first year of life, with 59.2% (90/152) and 61.7% (37/60), respectively, occurring in the first 2 years of life. The most frequent infectious diagnosis was oropharyngeal thrush (n = 117, 42.4%); the most common inflammatory diagnosis was diaper dermatitis (n = 71, 25.7%). There was a temporal decline in the prevalence of A (pre-HAART cohort, 123; post-HAART cohort, 29; p < 0.01) and B (pre-HAART, 55; post-HAART, 5; p < 0.01) mucocutaneous diagnoses. In children with perinatal HIV-1, there was a significant decline in CDC category A and B mucocutaneous diagnoses by temporal cohort, consistent with the introduction of antiretroviral medications and HAART. Clinical category A and B mucocutaneous diagnoses were most common in the first 2 years of life, emphasizing the importance of early HIV-1 testing and HAART initiation.

RESUMEN

Oropharyngeal candidiasis (OPC) is a very common oral symptom for HIV infected patients. OPC is often caused by overgrowth of commensal Candida strains which asymptomatically colonize oral cavity of HIV+ patients. HIV infection can not only weaken the systemic and local mucosal immunity but also interact with Candida species colonizing in oral cavity. These changes in host immunity and Candida species may facilitate Candida colonization in oral cavity of HIV infected patients. This review will discuss oral Candida colonization (including asymptomatic Candida carriage and OPC) prevalence, colonization spectrum, colonization intensity, relationship between oropharyngeal Candida colonization and peripheral blood CD4+ T cell counts, association of plasma levels of HIV RNA and Candida colonization, and other factors related with Candida colonization in HIV+ patients.

RESUMEN

BACKGROUND: Oral lichen planus (OLP) is seen frequently in patients with hepatitis C virus (HCV) infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN) therapy for HCV infection. METHODS: Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years) who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. RESULTS: Cultures of Candida from the tongue surfaces were positive in 7 (50.0%) of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14) of patients: OLP in three (21.4%), angular cheilitis in three (21.4%) and recurrent aphthous stomatitis in one (7.1%). OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1) and the 7 patients in whom Candida was not detected during IFN therapy (group 2). The prevalence of oral mucosal lesions (P=0.0075) and incidence of external use of steroids (P=0.0308) in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088). Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0.0550). According to multivariate analysis, one factor, the presence of oral mucosal lesions, was associated with the detection of Candida. The adjusted odds ratio for the factor was 36.00 (95% confidence interval 2.68-1485.94). CONCLUSION: We should pay more attention to oral candidiasis as well as other oral mucosal lesions, in patients with weight loss during IFN treatment.

RESUMEN

OBJECTIVE: To describe symptoms, physical examination findings, and set-point viral load associated with acute HIV seroconversion in a heterosexual cohort of HIV-discordant couples in Zambia. DESIGN: We followed HIV serodiscordant couples in Lusaka, Zambia from 1995 to 2009 with HIV testing of negative partners and symptom inventories 3 monthly, and physical examinations annually. METHODS: We compared prevalence of self-reported or treated symptoms (malaria syndrome, chronic diarrhea, asthenia, night sweats, and oral candidiasis) and annual physical examination findings (unilateral or bilateral neck, axillary, or inguinal adenopathy; and dermatosis) in seroconverting vs. HIV-negative or HIV-positive intervals, controlling for repeated observations, age, and sex. A composite score comprised of significant symptoms and physical examination findings predictive of seroconversion vs. HIV-negative intervals was constructed. We modeled the relationship between number of symptoms and physical examination findings at seroconversion and log set-point viral load using linear regression. RESULTS: Two thousand, three hundred and eighty-eight HIV-negative partners were followed for a median of 18 months; 429 seroconversions occurred. Neither symptoms nor physical examination findings were reported for most seroconverters. Seroconversion was significantly associated with malaria syndrome among nondiarrheic patients [adjusted odds ratio (aOR) = 4.0], night sweats (aOR = 1.4), and bilateral axillary (aOR = 1.6), inguinal (aOR = 2.2), and neck (aOR = 2.2) adenopathy relative to HIV-negative intervals. Median number of symptoms and findings was positively associated with set-point viral load (P < 0.001). CONCLUSION: Although most acute and early infections were asymptomatic, malaria syndrome was more common and more severe during seroconversion. When present, symptoms and physical examination findings were nonspecific and associated with higher set-point viremia.

RESUMEN

BACKGROUND: Oropharyngeal candidiasis (OPC) is the most common opportunistic infection among persons infected with human immunodeficiency virus (HIV). Once-daily miconazole 50 mg buccal tablet (MBT) is a novel delivery system using an extended-spectrum azole with potent in vitro activity against many Candida species, including some that may be resistant to other azoles. METHODS: This phase 3, double-blind, double-dummy, multicenter trial evaluated 578 randomized patients with HIV infection and OPC. The study compared the efficacy and safety of MBT once daily with clotrimazole 10 mg troches (CT) 5 times daily for 14 days. The co-primary efficacy endpoints were clinical cure at test of cure (TOC) visit (days 17-22) in the intent-to-treat (ITT) and per protocol (PP) populations. RESULTS: Clinical cure rate at TOC visit for MBT-treated patients was statistically noninferior to CT-treated patients in both the ITT (61% vs 65%) and PP (68% vs 74%) populations. Secondary endpoints, safety, and tolerability were similar between treatment groups. CONCLUSIONS: In this large trial, once-daily MBT was shown to be noninferior to CT 5 times daily in the treatment of OPC in HIV-positive patients. MBT offers an effective, safe, and well-tolerated topical treatment option for OPC administered as a convenient once-daily dose.

RESUMEN

BACKGROUND: The role of the oral mucosa as a target of human immunodeficiency virus (HIV-1) infection and persistence is unclear. HIV-1 has been reported in oral epithelial cells, but this has not been confirmed. Cellular reservoirs may impede antiretroviral therapies and should be identified. This study was performed to determine the presence of HIV-1 in oral epithelial and Langerhans cells (LCs) of HIV-1-positive antiretroviral naïve patients. Non-invasive brush biopsy technique for future in vivo HIV research was also evaluated. METHODS: Oral mucosal cells were harvested from the buccal mucosae, dorsal tongue and the gingiva of the mandibular teeth of 35 HIV-1-positive patients using a Cytobrush Plus cell collector. Epithelial cells were purified from the samples by flow cytometric cell sorting using cytokeratin stains after which the epithelial cell samples were further purified and divided into superficial and deep epithelial cells by laser microdissection on Pap stained cytospin smears. LCs were picked up individually by laser microdissection from CD1a stained cytospin smears. Purified epithelial and LC samples were tested for the presence of HIV-1 DNA by polymerase chain reaction analysis. RESULTS: Ten of the patients had HIV-1 DNA in one or more of the sampled anatomical locations. No HIV-1 DNA could be demonstrated in any of the purified superficial or deep epithelial or LC samples. CONCLUSIONS: HIV-DNA can be found using non-invasive oral brush biopsies and should be investigated further as an experimental model for in vivo oral HIV research. Better ways to purify the different cell types should be investigated.

RESUMEN

OBJECTIVE: We aimed to describe factors associated with mortality among children receiving antiretroviral treatment (ART) at a pediatric hospital in Kinshasa, Democratic Republic of the Congo. RESULTS: Two hundred ninety-nine children, <18 years old, were followed for a median of 77 weeks (interquartile range: 61-103) post-ART initiation. Survival probability was 89.6% [95% confidence interval (CI): 85.5-92.6%] at 12 months; 24 of 31 deaths (77.4%) occurred within 2 months of ART initiation. Predictors of mortality in bivariate analysis were >/=2 opportunistic infections before ART initiation, severe immunosuppression as defined by age-specific CD4 count or percentage criteria, hemoglobin <9 g/dL, oral candidiasis, and severe malnutrition. In multivariate analysis, weight for age z-score [hazard ratio (HR): 0.39; 95% CI: 0.27-0.61; P < 0.001] and oral candidiasis (HR: 5.86; 95% CI: 2.34-14.65; P = 0.0002) were independent predictors of mortality. Suspected septic shock was the most common cause of death (n = 12/31, 38.7%). CONCLUSIONS: Children receiving ART in this resource-poor setting were at the highest risk of dying in the first 2 months of ART, particularly when they presented with malnutrition or oral candidiasis. Optimal timing of ART initiation during nutritional rehabilitation should be determined. Promotion of early care seeking, strengthened health care, and prevention services are important to further improve outcome of pediatric ART in resource-poor settings.

RESUMEN

Oropharyngeal candidiasis (OPC) continues to be a common opportunistic infection in patients infected with Human Immunodeficiency Virus (HIV) and is predictive of increasing immunosuppression. Though Candida albicans remains the predominant isolate, a rise in the frequency of isolation of non-albicans Candida (NAC) species is being observed. The levels of virulence and the sensitivities to available antifungal drugs vary among these species. Of 340 HIV seropositive patients in this study, 132 (38.8%) had oral lesions suggestive of candidiasis. Samples were collected from the lesion using sterile cotton swabs. Isolation and speciation were done by standard techniques. Antifungal drug susceptibility testing was done by macro broth dilution. The total number of Candida isolates was 135, of which, 45 (33.3%) were NAC species and 90 were C.albicans (66.6%). Of the NAC species, C. dubliniensis was the predominant pathogen (22,48.9%). Antifungal susceptibility testing showed that 14 (31.1%) of the NAC species and 11 (12.2%) of C. albicans were resistant to fluconazole (MIC > 8 microg/ml). A very high MIC of > 32 microg/ml was noted among the NAC species resistant to fluconazole.

RESUMEN

OBJECTIVES: To estimate oral disease prevalence among Zimbabwean women by HIV serostatus and CD4 cell count and to assess accuracy of oral disease diagnoses made by nurses as compared with an oral surgeon. METHODS: Standardized oral mucosa examinations were performed by trained nurse-examiners and by an oral surgeon among women recruited in Harare, Zimbabwe. RESULTS: A total of 461 women (320 HIV-infected, 141 uninfected) were seen by nurses and an oral surgeon within a 2-week period. Oral candidiasis (OC) was the most common lesion diagnosed in nearly one quarter of HIV-infected women, whereas hairy leukoplakia and Kaposi sarcoma were found in <3%. The prevalence of OC diagnosed by nurses or the surgeon was significantly higher among women with a CD4 count <200 cells/mm than in women with a CD4 count from 200 to 499 cells/mm3 or a CD4 count >499 cells/mm3. The sensitivity of nurse examinations compared with examinations by the oral surgeon among HIV-infected women for the diagnosis of OC was 73%, the specificity was 95%, and the kappa-statistic was 0.71. CONCLUSIONS: OC was the most common lesion in HIV-infected women and was strongly associated with a low CD4 cell count. Interexaminer agreement was good for the diagnosis of OC among HIV-infected women. This study suggests that OC may play a role, in combination with other clinical indicators as a marker of disease progression in resource-poor settings.

RESUMEN

Oral lesions are common in women and children with HIV/AIDS and may decrease the overall quality of life in these patients because of pain, dry mouth, and difficulty in eating. An oral cavity screening is an easy, noninvasive, quick, and inexpensive procedure that provides nurses with invaluable information about the need for referral, treatment, and health education. Nurses can use the information obtained from a careful oral screening to decrease the symptoms experienced with oral lesions and optimize a patient's ability to chew and enjoy food. Common oral manifestations of HIV infection include fungal, viral, and bacterial infections, although neoplasms, periodontal disease, salivary gland disease, and lesions of uncertain origin are also seen. Oral lesions such as candidiasis, oral hairy leukoplakia, herpetic ulcers, and Kaposi's sarcoma are often among the first symptoms of HIV infection.

RESUMEN

BACKGROUND: Oral lesions are often characteristic in HIV patients and in the majority of cases can be diagnosed by their clinical features alone. To date there is no study addressing the prevalence of oral and perioral lesions in HIV patients in Ethiopia. OBJECTIVES: To assess prevalence of oral and perioral manifestations, the clinical symptoms of oral disease, and to assess the association of oral and perioral lesions to the socio- demographic status and CD4 count of ART naive HIV patients. METHODS: A cross-sectional study on 384 consecutive HIV patients before initiation of ARV treatment was conducted. Oral and perioral lesions were diagnosed according to the EC-clearinghouse's classification and diagnostic criteria for oral lesions in HIV infection and WHO collaborating centre on oral manifestations of HIV, 1992. RESULTS: One hundred and twenty six (32.8%) of the study subjects were males and 258 (67.2%) were females and mean age was 35.4 +/- 9.94 years (range of 14-84 years). Overall prevalence of oral lesions was 64.3%, and perioral lesions was 15.4%. Nearly half (44%) had dental caries. Pseudomembraneous candidiasis (20.1%), linear gingival erythema (11.7%), and erythematous candidiasis (9.1%) were the three most common HIV associated oral lesions. Angular cheilitis (8%) and molluscum contagiosum (4%) were the two most common perioral conditions. The most common oral symptoms reported were dry mouth (34.4%), difficulty eating (27.9%), and oral pain (27.3%). Oral symptoms and a CD4 count < 200 mm(-3) were significantly (X2 = 22.4, P = 0.0001) associated with presence of oral and perioral lesions. Age above 40 years (31%) was significantly associated with oral lesions (P = 0.016), but not with perioral lesions (P = 0.26). CONCLUSION: Oral and perioral lesions were common in HIV positive adults at Tikur Anbessa Specialized hospital and represent a treatable morbidity associated with this disease. Thus, a comprehensive oral examination is important in the clinical evaluation, management, and follow up of patients with HIV.

RESUMEN

OBJECTIVE: Oropharyngeal candidiasis (OPC), caused by Candida albicans, is the most common oral infection in HIV(+) persons. Oral epithelial cells are considered important for innate host defense against OPC with production of cytokines in response to C. albicans and the ability to inhibit Candida growth in vitro. The purpose of this study was to determine if Candida similarly induces cytokines by oral epithelial cells from HIV(+) persons, including those with OPC, as well as to determine if cytokines can influence the oral epithelial cell anti-Candida activity. METHODS: Supernatants from oral epithelial cells from HIV(+) persons with and without OPC cultured with Candida were evaluated for cytokines by ELISA, or cytokines were added to the standard growth inhibition assay using epithelial cells from HIV(-) persons. RESULTS: Results showed low Candida-induced epithelial cell cytokine production from HIV(+) persons, but with some elevated proinflammatory cytokines (TNF-alpha, IL-6) in those with OPC compared to those without OPC. The addition of specific proinflammatory or Th cytokines had no effect on oral epithelial cell anti-Candida activity in healthy HIV(-) persons. CONCLUSION: These results suggest that oral epithelial cells from HIV(+) persons can contribute at some level to the oral cytokine milieu in response to Candida during OPC, but that cytokines do not appear to influence oral epithelial cell anti-Candida activity.

RESUMEN

In this study, we investigated the yeasts colonization of genus Candida, including C. dubliniensis, isolated of HIV-infected patients oral cavities and we accessed in vitro susceptibility pattern of the Candida isolates to four antifungal agents. Out of 99 patients investigated, 62 (62.6%) were colonized with yeasts. C. albicans was the prevailing species (50%). C. dubliniensis isolates were not recovered in our study. We verified that 8.1% of the yeasts isolated were resistant to fluconazole, 8.1% to itraconazole and 3.2% to voriconazole. The isolates demonstrated very low voriconazole MICs, in which 79% (49/62) presented values of 0.015 mug/ml. All Candida isolates were susceptible to amphotericin B. The results reported here showed that although C. albicans continues to be present in one-half of oral Candida carriage of HIV-infected patients, Candida non-albicans species are increasing among these patients. Besides, the findings of resistant isolates endorse the role of antifungal susceptibility testing whenever antifungal treatment with azoles is planned.
