Background and Purpose: Candida species are the common opportunistic pathogens during the course of human immunodeficiency virus (HIV) infection. Oropharyngeal candidiasis (OPC) is generally known as the initial sign of HIV infection. The aim of this study was to compare demographic characteristics and frequency of Candida species between HIV/AIDS patients and non-HIV subjects in Kerman, southeast of Iran. Materials and Methods: This study was conducted on 143 samples collected from the oral cavity of 81 HIV/AIDS patients and 35 non-HIV subjects. The samples were cultured on Sabouraud dextrose agar and CHROMagar. The identification of Candida species was accomplished using the color of colony and polymerase chain reaction-restriction fragment length polymorphism. Results: According to the results, C. albicans (n=25, 69.14%) was the most prevalent species isolated from the HIV/AIDS patients, followed by C. glabrata (n=19, 23.46%). Other isolated species included C. parapsilosis (n=4, 4.94 %), C. krusei (n=1, 1.24%), and C. kefyr (n=1, 1.24%). Out of the 35 Candida species recovered from the oral samples of non-HIV subjects, 23 (65.71%) and 12 (34.29%) cases were C. krusei and C. albicans, respectively. Candida krusei was the only non-albicans species found in the non-HIV subjects that was also the predominant isolated species. Regarding the HIV/AIDS patients, the highest prevalence of OPC was observed in the age group of 41-50 years. However, in the non-HIV subjects, the age group of 31-40 years had the highest prevalence of this infection. Furthermore, no correlation was observed between the gender and number of Candida isolates. Conclusion: Consideration of the epidemiologic data showed that the two groups were significantly different in terms of the prevalence of Candida species, which could play a major role in the selection of effective drugs for the treatment of candidiasis.

Background and Purpose: Aspergillus fumigatus as a ubiquitous fungus can be found in the respiratory tract of the asthmatic and healthy people. The inhalation of Aspergillus spores leads to an immune response in individuals with asthma and results in the aggravation of the clinical symptoms. The present study aimed to investigate the prevalence of specific immunoglobulin E and G (IgE and IgG) against A.fumigatus in asthmatic patients. Materials and Methods: This study was conducted on 200 consecutive patients with moderate to severe asthma referring to Masih Daneshvari hospital Tehran, Iran, from January 2016 to February 2018. Skin prick test (SPT) was performed in all subjects with Aspergillus allergens. Moreover, all patients underwent specific IgE testing for Aspergillus using Hycor method. Enzyme immune assay was applied to measure total IgE and Aspergillus-specific IgG. Results: According to the results, the mean age of the patients was 45.8 years (age range: 18-78 years). The mean levels of total IgE and Aspergillus specific IgE in asthmatic patients were obtained as 316.3 (range: 6-1300 IU/ml) and 1.5 (range: 0.1- 61.3 IU/ml), respectively. Out of 200 patients, 27 (13.5%), 65 (32.5%), 22 (11.0%), and 86 (43.0%) cases had positive Aspergillus SPT, total IgE of > 417 IU/ml, Aspergillus-specific IgE, and IgG, respectively. The level of these variables in patients with severe asthma were 16 (16.5%), 36 (37.1%), 15 (15.5%), and 46 (47.4%), respectively. Conclusion: As the findings indicated, reactivity to Aspergillus is a remarkable phenomenon in asthmatic patients. It is also emphasised that the climatic condition may affect the positive rate of hypersensitivity to Aspergillus.

Background and Purpose: Candida albicans is the most prevalent Candida species isolated from animals. Candidiasis can be systemic in animals or may affect a single organ, such as the mouth, urinary tract, and skin. The aim of the present study was to determine the genetic diversity of C. albicans isolated from different animals and investigate the presence of a relationship between host specificity and genetic typing of C. albicans. Materials and Methods: For the purpose of the study, DNA extraction was performed on 27 clinical isolates of C. albicans obtained from animals. Subsequently, they were subjected to 25S ribosomal DNA amplification and ALT repeats in repetitive sequences (RPSs). The minimum inhibitory concentrations of fluconazole, ketoconazole, clotrimazole, nystatin, amphotericin B, and caspofungin were determined using the microdilution method based on the Clinical and Laboratory Standards Institute M27-S4 standard. Results: Out of 27 C. albicans strains, 11, 6, 5, and 5 cases were recognized as genotypes A (40.8%), E (22.2%), B (18.5%), and C (18.5%), respectively, through amplification using AS-I, which revealed 17 different types of C. albicans. By combining the two typing methods, 27 C. albicans strains were finally divided into 22 genotypes. Conclusion: Different genotypes showed genetic diversity among the C. albicans strains isolated from animal sources. The results revealed no special genotype relationship according to the host, anatomical source of isolation, and antifungal susceptibility.

Background and Purpose: Oral candidiasis is one of the most common fungal infections in humans. The treatment and prophylaxis of the patients suffering from this infection require the identification of new anti-Candida agents with no side effects or toxicity like medicinal plants. The present study was conducted to compare the antifungal activities of the aqueous, ethanolic, and methanolic extracts of the bark and roots of P. granatum with those of two routine antifungal agents (i.e., fluconazole and nystatin) on oral Candida strains isolated from liver transplant recipients. Materials and Methods: Minimum inhibitory concentrations (MICs) of the ethanolic, methanolic, and aqueous extracts of the bark and root of Punica granatum against C. albicans and C. glabrata isolated from oral cavities were evaluated according to the CLSI M27-A3. All data were analyzed in SPSS (version 16.0) by pairwise comparison and Kruskal-Wallis test. Results: The MIC50 and MIC90 values for the methanolic and ethanolic extracts of the bark and root of P. granatum against C. albicans were both obtained as 0.05 mg/ml with the geometric mean (GM) of 0.07. Furthermore, the MIC90 values for the aqueous extracts of bark and root were estimated as 0.05 and 0.2 mg/ml, respectively. With regard to C. glabrata, the MIC50 and MIC90 values for the methanolic and ethanolic extracts of the bark and root were 0.05 mg/ml. However, the MIC90 value for the aqueous extract against this species was obtained as 25 mg/ml. The GM values for the aqueous extracts of the bark and root were 9.49 and 0.32, respectively. Conclusion: As the findings indicated, the methanolic and ethanolic extracts of the bark and root of Punica granatum had anti-Candida activities. Therefore, they can be considered as mouthwash or toothpaste to prevent and treat Candida infections in the oral cavity.

Background and Purpose: The incidence of invasive fungal infections has been increased in recent years. The growing use of azole drugs for prophylactic and therapeutic purposes has resulted in the gradual emergence of azole-resistant species. Accordingly, the introduction of a new strategy to improve the management of Candida infections is an urgent need. Regarding this, the present study was performed to evaluate the antifungal activities of crocin (Cro) alone and in combination with fluconazole. Materials and Methods: This study was conducted on 50 clinical isolates of four different Candida species. The identity of the isolates was confirmed using the internal transcribed spacer identification system. The interactions of Cro with fluconazole were investigated using a microdilution checkerboard method based on the Clinical and Laboratory Standards Institute reference technique with 96-well microtiter plates. Furthermore, the assessment of the interaction of drug combinations was accomplished using the fractional inhibitory concentration index (FICI) based on the Loewe additivity theory. Results: According to the results, Cro alone showed a relatively high MIC50 value (1 g/ml) against Candida species. Our results demonstrated indifferent interactions between Cro and fluconazole with a FICI range of 0.5-4 against Candida strains. Conclusion: The high MIC value for Cro against Candida species indicated its failure to show appropriate antifungal activity against this species. The MIC of this agent was not significantly reduced even by the addition of fluconazole. Therefore, other mechanisms which are not related to the mechanism of azole drugs are involved at high concentration of Cro.

Skin is an important organ of the body due to offering an accessible and convenient site for drug administration. One of the disadvantages of transdermal drug delivery is the low penetration rate of drugs through the skin. Over the past decades, nanoparticles have been used as drug delivery systems to increase therapeutic effects or reduce toxicity. Encapsulation of drugs in nanoparticulate vesicles simplifies the transports of drugs into and across the skin. Niosome nanoparticles are among these drug delivery systems, which have numerous applications in drug delivery and targeting. Niosomes are frequently used for loading drugs serving different purposes (e.g., anticancer, antiviral, and antibacterial agents). In recent years, there has been much research on the use of niosomal systems for the delivery of fungal drugs. A review of the literature investigating the advantages of niosomes in antifungal drug delivery can elucidate the efficiency and superiority of this nanocarrier over other nanocarriers.

Invasive fungal infections (IFIs) are among the life-threatening issues in patients with impaired immune system. High administration of antifungals in these patients imposes a heavy economic burden on the national health system. In addition, despite the usually expensive antifungal regimens, the mortality rate due to fungal infections is still high, resulting in the loss of hundreds of lives per year. Survival rate is an indicator of the success of national healthcare policies. Early diagnosis of IFI is critical because any delays may be fatal. The weakness of the old-fashioned culture-based diagnostic methods lies in their time-consuming laboratory procedures. To overcome this problem, several diagnostic approaches have been developed to facilitate the early diagnosis of invasive candidiasis as the most prevalent IFI. These methods are based on the detection of serologic and molecular footprints. However, nowadays, antibiotic resistance and proper and cost-effective use of antibiotics are given special attention in national healthcare policies. The instructions for controlling these indices have been collected under the name of antibiotic stewardship. The present review study was targeted toward providing insight into novel diagnostic biomarkers and antifungal stewardship programs. The simultaneous investigation of these two issues facilitates the achievement of a novel health policy for the treatment of systemic candidiasis in immunocompromised patients. Keywords:
