Gene expression of SAP 4-6 based on the detection of mRNA was observed in Candida albicans isolates from HIV-positive patients with oral candidiasis and commensal from healthy individuals. The species of C. albicans strains were selectively isolated from both sources using CHROMagar Chromogenic Media. The obtained isolates were then induced to express SAP 4-6 using SAP 4-6 gene inducer media. Analysis of gene expression was performed on a molecular basis using the RT-PCR method. Molecular analysis of gene expression showed that the isolates CH3 from HIV-positive patients with oral candidiasis could express SAP 4-6 gene, while commensal isolates from healthy people could not. Based on the results of this study, it could be concluded that, in terms of molecular detection, only isolates from HIV-positive patients (CH3) could express their SAP 4-6 gene.

Oral candidosis in non-Hodgkin's lymphoma: a case report

J Oral Sci, 2003 Sep;45(3):161-4.

PMID: 14650581

Though oral candidosis is an opportunistic fungal infection that commonly affects immunocompromised patients, little is known of its occurrence as a complication of Non-Hodgkin's lymphoma. This paper reports a case of oral candidosis in a 20-year-old Indonesian woman with this lymphoproliferative disease. She presented with acute pseudomembranous candidosis on the dorsum and lateral borders of the tongue, bilateral angular cheilitis and cheilocandidosis. The latter is a rare clinical variant of oral candidosis, and the lesions affecting the vermilion borders presented as an admixture of superficial erosions, ulcers and white plaques. Clinical findings were confirmed with oral smears and swabs that demonstrated the presence of hyphae, pseudohyphae and blastospores, and colonies identified as Candida albicans. A culture from a saline rinse was also positive for multiple candidal colonies. Lip and oral lesions were managed with Nystatin. The lesions regressed with subsequent crusting on the lips, and overall reduction in oral thrush. As Non-Hodgkin's lymphoma is a neoplastic disease that produces a chronic immunosuppressive state, management of its oral complications, including those due to oral candidosis, is considered a long-term indication.

Chronic mucocutaneous candidiasis with deficient CD2 (E receptor) but normal CD3 mononuclear cells

Noh LM, Hussein SH, Sukumaran KD, Rose I, Abdullah N

J Clin Lab Immunol, 1991 Jun;35(2):89-93.

PMID: 1688166

A case of chronic mucocutaneous candidiasis in a Malaysian child who subsequently developed disseminated tuberculosis and toxoplasmosis is described. The phenotype of her peripheral blood mononuclear cells showed discordance for her T cell markers. The presence of a subpopulation of CD2-/CD3+ mononuclear cells leading to an immunodeficiency state is consistent with failure of activation of CD2-mediated alternative pathway resulting in immunodeficiency. Such abnormal CD2-/CD3+ subpopulations have been described in lepromatous leprosy and foetal abortuses.

Fulltext Oral Candidal Load and Oral Health Status in Chronic Obstructive Pulmonary Disease (COPD) Patients: A Case-Cohort Study

Khijmatgar S, Belur G, Venkataram R, Karobari MI, Marya A, Shetty V, et al.

Biomed Res Int, 2021;2021:5548746.

PMID: 34545329 DOI: 10.1155/2021/5548746

Objective: The objective of this study was to determine the candidal load of the patients with Chronic Obstructive Pulmonary Disease (COPD) and evaluate the oral health status of subjects with COPD. Material and Methods. N = 112 COPD subjects and N = 100 control subjects were included in the study. The selection of COPD cases was confirmed based on the set criteria from the American College of Physicians. The oral health status was assessed as per WHO criteria to determine the score of decayed, missing, and filled teeth (DMFT), significant caries index (SiC), community periodontal index and treatment needs (CPITN), and oral hygiene index-simplified (OHI-S). Gram staining was performed to identify Candida using the whole saliva. Quantitative evaluation of the candidal load was carried out using Sabouraud Dextrose Agar (SDA). Chrome agar was used to differentiate between the commensal carriages. A statistical analysis paired t-test and 95% confidence interval (CI) for proportions was carried out using STATA software.

Results: Candidal growth was found in 21.42% (n = 24) of COPD cases and 1.1% (n = 11) of control cases (p < 0.05) (95% CI 0.45, 0.59). The DMFT score was 8.26 in COPD subjects and 4.6 in controls, the SiC score was 16.42 in COPD subjects and 10.25 in controls, and the CPITN score for both COPD and control cases was score 2.

Conclusion: In conclusion, there was a higher candidal load among subjects suffering from COPD. Theophylline medication can be a risk factor for increased candidal load in COPD patients.

Managing complications of radiation therapy in head and neck cancer patients: Part VI. Management of opportunistic infections

Ngeow WC, Chai WL, Ramli R, Rahman RA

Singapore Dent J, 2006 Dec;28(1):19-21.

PMID: 17378338

Head and neck cancer is becoming a more recognizable pathology to the general population and dentists. The modes of treatment include surgery and/or radiation therapy. Where possible, pretreatment dental assessment shall be provided for these patients before they undergo radiation therapy. There are occasions, however, whereby head and neck cancer patients are not prepared optimally for radiation therapy. Because of this, they succumb to complicated oral adverse effects after radiation therapy. The last part of this series reviews the opportunistic infections that can occur to the perioral structure. Their management is briefly discussed.

Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients.

The AIDS epidemic in Southeast Asia has led to a marked rise in the incidence of talaromycosis (penicilliosis) marneffei. The aim of this cross-sectional study was to determine the clinico-epidemiological features and outcome predictors of talaromycosis in Malaysia. We identified Talaromycosis marneffei cases from cultures of sterile specimens from 191 human immunodeficiency virus (HIV)- infected patients. Talaromycosis increased from 20-25 (2010-2011) to 45-50 cases per year (2012-2014). Talaromycosis was the HIV-presenting illness in 117 (61.3%) patients. The incidence of talaromycosis as HIV-presenting illness showed an increasing trend from 10.7 (2010) to 26.4 (2014) cases per 1000 new HIV patients. The patients were between 19 and 74 of age (mean 37.2+9.4 years) and the male to female ratio was 7.7:1. Malay (73, 38.2%) and Chinese (70, 36.3%) were the most prevalent ethnic groups. Common clinical manifestations included loss of weight (85.9%), fever (84.8%) and cough (67%), while skin lesions were only present in 42.9% cases. Common concurrent infections were oral candidiasis (79.6%), tuberculosis (36.1%) and hepatitis C infection (20.9%). Most patients (93.7%) were anaemic with mean haemoglobin level of 9.9+2.3 g/dL, 39% had impaired liver function, and 18.8% were neutropaenic. Median CD4 cell count was 16 cells/L. Most patients (70.4%) received intravenous amphotericin B followed by itraconazole. At 8-month follow up, 148 (81.8%) patients were alive while 33 (18.2%) had died. Intravenous drug abuse, concurrent toxoplasma encephalitis and concurrent Pneumocystis jiroveci pneumonia independently predicted death outcome in both univariate and multivariate logistic regression analyses.
