Oral manifestations in a patient with a history of asymptomatic COVID-19: Case report

The pandemic situation has led to public health measures that have forced patients with and without the SARS-CoV-2 virus to remain isolated and take steps to prevent the spread. Many of these patients have been unable to attend the control of medical-dental services, which in many cases complicates their situation. This study reports on the oral manifestations of an asymptomatic COVID-19 patient treated interdisciplinary by teleconsultation due to the sudden appearance of lesions in the oral mucosa. Lesions are diagnosed, therapeutic measures are taken, and improvement is shown. This case shows that the problems that arise in the oral mucosa in patients with suspected or confirmed SARS-CoV-2 infection can be monitored through interdisciplinary teleconsultation during the pandemic with the support of information technology currently available worldwide. It also decreases the risk of transmission of SARS-Cov-2 between patients and health professionals.

(A1) Identification of Oral Health Care Needs in Children and Adults, Management of Oral Diseases

The workshop considered five questions reviewing the identification of international oral health care needs of children and adults, and the management of oral diseases in resource-poor countries: (1) What is the role of the dental profession in the management of the HIV-infected individual? (2) Identifying health care needs-What are the epidemiology and disparities of HIV-associated oral lesions in children from different continents? (3) How effective is HIV treatment in controlling oral diseases? (4) Could we develop basic inexpensive oral and dental care protocols for economically deprived HIV-infected patients? and (5) What is the best method of arranging resources to meet the oral health care needs of people with HIV disease? The consensus of the workshop participants was that there is a need to re-target research efforts to non-established market economy countries and prioritize research in these regions to children with HIV disease. It will be important to assess commonalities and variations in oral health needs across geographical and cultural boundaries, and research efforts should be centralized in resource-poor countries to support multi-center longitudinal standardized studies. It is essential that oral health research be integrated into other health care research programs, to make these research priorities and public health initiatives feasible.

Prevalence of oral candidiasis in HIV/AIDS children in highly active antiretroviral therapy era. A literature analysis

SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy.

Levels of salivary IgA antibodies to Candida spp. in HIV-infected adult patients: a systematic review

OBJECTIVE

To perform a systematic review of published data with the aim of evaluating the levels of IgA antibodies to Candida albicans in HIV-infected adult patients.

METHODS

The search strategy was based on PubMed, Web of Science, Google Scholar, Cochrane and EMBASE databases. Also, the reference lists of included studies were searched. All abstracts found by electronic searches were independently scrutinized by two reviewers. To be eligible for review, the controlled studies had to present the following characteristics: samples of both HIV-infected adults and noninfected adults; appropriate HIV-diagnostic tests for both patient groups (case and control); IgA-diagnostic test applied to a similar population sample.

RESULTS

Of 144 studies found, only six met the initial eligibility criteria, but three were excluded after a thorough analysis. To assess the methodological quality of the three remaining studies, they were categorized according the risk of bias. The three selected studies revealed that the levels of C. albicans-specific IgA antibody were higher in HIV-infected individuals compared with the control group.

CONCLUSION

Adequate IgA antibody responses to C. albicans appear to be maintained, since the levels of these antibodies were higher in all studies selected. Although the findings of this systematic review are encouraging, the scientific evidence should be interpreted carefully because there are only a few reports in the literature, mostly because of the lack of important methodological details or the varying methodologies employed.

Salivary microbiota of HIV-positive children and its correlation with HIV status, oral diseases, and total secretory IgA

AIM

This study aimed to investigate the prevalence and levels of salivary microorganisms in HIV-positive children, and their correlation to HIV status, oral lesions, and salivary IgA levels.

DESIGN

Forty-two HIV-positive and 36 control children were clinically examined, had their saliva collected and processed for the microbiological analysis of 38 bacterial taxa by the checkerboard method, and salivary IgA quantification by ELISA.

RESULTS

The majority of the species tested were more prevalent in control children than in the HIV group. Mean concentration of total salivary IgA was similar in both groups. High levels of Veillonella parvula were found in children with cheilitis and herpes. Tannerella forsythia, Eikenella Corrodens, and Propionibacterium acnes were prevalent in children with gingivitis, while Fusobacterium periodonticum, Streptococcus gordonii, and Streptococcus oralis were significantly more frequent in children with no oral lesions. Significant negative correlations between salivary IgA levels and Eubacterium nodatum and oral streptococci were observed (P < 0.05).

CONCLUSION

HIV-seropositive children presented significantly lower prevalence and levels of several bacterial species in saliva; HIV-positive children are able to mount a mucosal immune response; HIV-seropositive children under highly active antiretroviral therapy presented low prevalence of oral lesions.

Prevalence of oral hairy leukoplakia in 120 pediatric patients infected with HIV-1

Oral hairy leukoplakia (OHL) is an EBV (Epstein-Barr virus) opportunistic infection found in HIV-infected patients. It is an asymptomatic lesion that has an important prognostic value in AIDS. Differently from what takes place with HIV adult patients, OHL has been described in the literature as having a very small prevalence in pediatric patients. Therefore, the aim of this study was to investigate the prevalence of OHL in HIV pediatric patients using cytopathology. The sample consisted of 120 patients who were submitted to oral examination and had material scraped from both sides of their tongues. The diagnostic criterion was based on the identification of nuclear alterations. Clinical OHL was identified in two (1.67%) patients. The cytopathology revealed twenty (16.7%) cases of subclinical OHL. Our results show that in pediatric patients the prevalence of OHL may be larger than that described in the literature.

Oral manifestations of HIV infection in 36 Nigerian children

Oral manifestations of HIV/AIDS are early and common clinical indicators of HIV infection. There has been no report on the clinical prevalence of oral lesions associated with HIV infection in children in sub-Saharan Africa. We report the findings of a cross sectional study of 36 Nigerian children seen at the Pediatrics Infectious Disease Clinic of the AIDS Prevention Initiative in Nigeria (APIN), Jos University Teaching Hospital (JUTH) Jos, Nigeria.

Viral coinfection in the oral cavity of HIV-infected children: relation among HIV viral load, CD4+T lymphocyte count and detection of EBV, CMV and HSV

Viral coinfection in the oral cavity associated to HIV infection was evaluated in 180 children from birth to 13 years of age of both sexes. The oral examinations were performed at the Pediatric AIDS Outpatient Clinic, São Lucas Hospital and Clinic Hospital, both in Porto Alegre, Brazil and at the School of Dental Medicine, University Hospital Center, State University of New York at Stony Brook, USA. The aim of this study was to identify the presence of viral infections in the oral cavity. PCR technique was used to determine opportunistic viral infections caused by CMV, EBV, and HSV in mucosal swabs. A high frequency of viral infection was detected in the oral cavity of HIV-infected children determined by the PCR technique. HIV-infected children with viruses had a favorable CD4+T lymphocyte count and unfavorable viral load.

Pediatric HIV-related oral manifestations: a five-year retrospective study

The purpose of this study was to carry out a five-year retrospective descriptive follow-up of the oral manifestation frequency, systemic condition and type of medication used in HIV-infected children and adolescents after the introduction of combined antiretroviral therapy. Fifty-eight patients were examined in 2001/2002, and their previous medical and dental records (1997 to 2000) were researched from files. There was an occurrence of 7 new cases of AIDS in a sample of 19 children, while 46.5% of the entire sample (n = 58) progressed as to classification of HIV infection. No difference was noted among the frequencies of oral manifestations, categories of the immunosuppression and viral load categories. The oral manifestations in the group of children and adolescents followed up in this study remained stable, even after treatment with combined antiretroviral therapy. However, a downward trend in the frequency of oral candidiasis and parotid enlargement was noted.
