RESUMEN

A 42-year-old male patient presented with profound impairment of vision in both eyes, just as he was recovering from COVID-19. A known diabetic and hypertensive, he suffered from COVID-19 pneumonia further complicated by ARDS, septicaemia and acute kidney injury. His vision on presentation was finger counting close to face bilaterally with multiple, yellowish lesions at the posterior pole. Based on the clinical findings and previous blood culture report, it was diagnosed as candida retinitis and treated with oral and intravitreal anti-fungals. The lesions were regressing at follow-up. This is a post COVID-19 presumed candida retinitis case report.

RESUMEN

INTRODUCTION: The role of fungi in infections in immunocompromised patients is a growing problem in both diagnosis and treatment. Candida species are the most common cause of fungal, endogenous endophthalmitis and infections of the cornea. CASE STUDY: A patient was admitted to hospital due to acute inflammation of the tissue of the left orbit, 1.5 years after the corneal penetrating transplantation of the left eye with intracapsular extraction of lens and simultaneous anterior vitrectomy. The microbiological system identified: Streptococcus pyogenes, Staphylococcus aureus, and Candida glabrata in the patient. CONCLUSIONS: The factors conducive to fungal infections are: patient's old age, immune disorders and diabetes, as well as the presence of a necrotic tissue or a foreign body. All these parameters were met in this case. Only antibiotic therapy and long-term antifungal therapy, together with surgical debridement of the site of the ongoing infection produces clinical effects in such severe cases.

RESUMEN

Candida lesion of Palatine tonsils was studied in 32 HIV-infected patients in the late stages of the disease using histological and cytological methods. There were used conventional methods during pathomorphological studies of palatine tonsils tissue fragments obtained by biopsy, and smears from the surface of the organ. It was found that micromycetes Candida spp. were located in association with various bacteria (mainly Streptococcus spp.), as well as Cryptococcus spp., with the formation of the biofilms, both on the surface of the Palatine tonsils and in the depth of their parenchyma. We revealed the minimal response cellular protective reaction to the deep introduction of the pathogen. Mycosis proceeded against the background of pronounced follicular lymphoid depletion of the tissue of the Palatine tonsils. The examined patients represent a risk group for invasion of Candida micromycetes into the vascular channel and their dissemination with the development of generalized candidiasis.

RESUMEN

Sexually transmitted infections (STIs) disproportionately affect young people, with more than half of the infections occurring in youth aged 15 to 25 years. (1)(2) This review, the second in a 2-part series on STIs, focuses on infections that may cause abnormal vaginal or penile discharge, including trichomonas, chlamydia, gonorrhea, and pelvic inflammatory disease (PID). Most infected persons, however, are asymptomatic. Nucleic acid amplification tests are the most sensitive and specific for the detection of chlamydia, gonorrhea, and trichomoniasis, and they can be performed on provider- or patient-collected swabs. Providers should have a low threshold for diagnosing and treating PID because untreated PID can have serious long-term complications for young women. Indications for hospitalization for PID include the presence of a tubo-ovarian abscess, severe illness with systemic symptoms, pregnancy, human immunodeficiency virus infection, and failure to respond to outpatient oral treatment (within 48-72 hours) or inability to tolerate the oral treatment.

RESUMEN

Detection of microbial nucleic acids in body fluids has become the preferred method for rapid diagnosis of many infectious diseases. However, culture-based diagnostics that are time-consuming remain the gold standard approach in certain cases, such as sepsis. New culture-free methods are urgently needed. Here, we describe Single MOLecule Tethering or SMOLT, an amplification-free and purification-free molecular assay that can detect microorganisms in body fluids with high sensitivity without the need of culturing. The signal of SMOLT is generated by the displacement of micron-size beads tethered by DNA probes that are between 1 and 7 microns long. The molecular extension of thousands of DNA probes is determined with sub-micron precision using a robust and rapid optical approach. We demonstrate that SMOLT can detect nucleic acids directly in blood, urine and sputum at sub-femtomolar concentrations, and microorganisms in blood at 1 CFU mL-1 (colony forming unit per milliliter) threefold faster, with higher multiplexing capacity and with a more straight-forward protocol than amplified methodologies. SMOLT's clinical utility is further demonstrated by developing a multiplex assay for simultaneous detection of sepsis-causing Candida species directly in whole blood.

RESUMEN

BACKGROUND: Although the majority of rashes in the diaper area are caused by irritation from urine and feces, irritant diaper dermatitis; IDD, there are some less common but potentially serious cutaneous eruptions associated with systemic diseases that should not be discounted. METHODS: This prospective descriptive study aimed to explore variation in cutaneous disease in the diaper area. It was conducted as a prospective descriptive study between October 2016 and November 2019 in the pediatric department of a tertiary-level hospital. RESULTS: Three hundred consecutive patients with rashes in the diaper area were enrolled. The most common diagnosed was IDD (125 cases; 41.7%), followed by rashes exacerbated by the diaper (101 cases; 33.67%) and non-diaper-related rashes (74 cases; 24.67%). CONCLUSIONS: Our finding suggests that when diagnosing rashes that occur in the diaper area, general pediatricians should consider, in addition to IDD, the possibility of less-common conditions. The simultaneous presence of cutaneous lesions at other sites was linked to diagnoses of systemic diseases other than IDD, (P < 0.001).

RESUMEN

BACKGROUND: Fungal otitis externa is prevalent in tropical and sub-tropical climates; however, over the past two decades, there has been a reported increase in the prevalence of otomycosis in paediatric patients from more temperate climates. This study aimed to review the children diagnosed with otomycosis at the University Hospital Limerick with reference to frequency, causative organism, predisposing factors and management. METHODS: A retrospective review was conducted of paediatric patients from 2001 to 2015. Patients with positive fungal ear swabs and a diagnosis of otomycosis were identified. RESULTS: Ninety-three patients were positive for candida (mean age, 5.8 years), 10 patients were positive for aspergillus (mean age, 9.1 years) and 1 patient had mixed fungal infection containing both fungi. There was a positive correlation between a diagnosis of otomycosis and prior treatment with topical fluoroquinolones (r = 0.8; p < 0.01). CONCLUSION: The incidence of otomycosis has been increasing since 2001, which correlates with an increase in the use of topical fluoroquinolones. Previous studies identify aspergillus as the commonest causative fungi; however, this study found that candida was the commonest isolated fungi in the paediatric population.

RESUMEN

BACKGROUND: Four new variants of Chlamydia trachomatis (nvCTs), detected in several countries, cause false-negative or equivocal results using the Aptima Combo 2 assay (AC2; Hologic). We evaluated the clinical sensitivity and specificity, as well as the analytical inclusivity and exclusivity of the updated AC2 for the detection of CT and Neisseria gonorrhoeae (NG) on the automated Panther system (Hologic). METHODS: We examined 1004 clinical AC2 samples and 225 analytical samples spiked with phenotypically and/or genetically diverse NG and CT strains, and other potentially cross-reacting microbial species. The clinical AC2 samples included CT wild type (WT)-positive (n = 488), all four described AC2 diagnostic-escape nvCTs (n = 170), NG-positive (n = 214), and CT/NG-negative (n = 202) specimens. RESULTS: All nvCT-positive samples (100%) and 486 (99.6%) of the CT WT-positive samples were positive in the updated AC2. All NG-positive, CT/NG-negative, Trichomonas vaginalis (TV)-positive, bacterial vaginosis-positive, and Candida-positive AC2 specimens gave correct results. The clinical sensitivity and specificity of the updated AC2 for CT detection was 99.7 and 100%, respectively, and for NG detection was 100% for both. Examining spiked samples, the analytical inclusivity and exclusivity were 100%, i.e., in clinically relevant concentrations of spiked microbe. CONCLUSIONS: The updated AC2, including two CT targets and one NG target, showed a high sensitivity, specificity, inclusivity and exclusivity for the detection of CT WT, nvCTs, and NG. The updated AC2 on the fully automated Panther system offers a simple, rapid, high-throughput, sensitive, and specific diagnosis of CT and NG, which can easily be combined with detection of Mycoplasma genitalium and TV.

RESUMEN

The use of biological drugs in psoriasis is replacing traditional therapies due to their specific mechanism and limited side effects. However, the use of Interleukin 17 inhibitors and the modification of its cytokine pathway could favor the risk of fungal infections. All-trans retinoic acid is an active metabolite of vitamin A with anti-inflammatory and immunoregulatory properties through its capacity to stimulate both innate and adaptive immunity and to its effects on proliferation, differentiation and apoptosis in a variety of immune cells. Furthermore, it has been recently discovered that All-trans retinoic acid has a direct fungistatic effect against Candida and Aspergillus Fumigatus. On the basis of these new insights, in the current review, we suggest that the evaluation of serum level of All-trans retinoic acid or vitamin A should be considered as a predictive marker for the development of fungal infections among psoriatic patients treated with Interleukin 17 inhibitors. In clinical practice, vitamin A test could be added in the routine hospital diagnostic management for a better selection of psoriatic patients eligible to Interleukin 17 inhibitors.

RESUMEN

Candida tropicalis is a prominent non-Candida albicans Candida species involved in cases of candidemia, mainly causing infections in patients in intensive care units and (or) those presenting neutropenia. In recent years, several studies have reported an increase in the recovery rates of azole-resistant C. tropicalis isolates. Understanding C. tropicalis resistance is of great importance, since resistant strains are implicated in persistent or recurrent and breakthrough infections. In this review, we address the main mechanisms underlying C. tropicalis resistance to the major antifungal classes used to treat candidiasis. The main genetic basis involved in C. tropicalis antifungal resistance is discussed. A better understanding of the epidemiology of resistant strains and the mechanisms involved in C. tropicalis resistance can help improve diagnosis and assessment of the antifungal susceptibility of this Candida species to improve clinical management.

RESUMEN

The aim of this study was to compare the Candida bromcresol green (BCG) medium with the chromogenic (CHROM) Brilliance Candida agar and Sabouraud dextrose agar (SDA) media in regard to their capability of detecting Candida isolates from mono- or dual-species cultures. We prepared Candida isolates' suspensions to obtain mono-species (n = 18) or dual-species (n = 153) culture plates per each medium, and three readers independently observed 513 plates at 24-h, 48-h and 72-h incubation time. We scored reading results as correct, over or under detection compared to the expected species number(s). BCG showed significantly higher correct-detection and lower under-detection rates for all Candida species when observed by at least one reader. At 24-h reading, 12 mono-species cultures had correct (or over) detections in all media, whereas 106, 60 and 78 dual-species cultures had correct (or over) detections in BCG, CHROM or SDA, respectively. BCG provides the basis for an accurate laboratory diagnosis of Candida infections.

RESUMEN

BACKGROUND: Invasive candidiasis is the most important health-care-associated fungal infection worldwide. In the last two decades, the cause of the increase of fungal infections is immunosuppression or serious underlying diseases. Additionally, Rhodotorula species, Blastoschizomyces capitatus, and Trichosporon species are emerging as important human pathogens in immunocompromised patients with hematological malignancy. METHODS: Between January 2012 and January 2018, a total of 603 fungal organisms were isolated from blood culture samples and included in the study. All of the isolates were identified by using standard mycological methods, MALDI TOF MS system, and the Phoenix system. Sequence analysis was performed on yeasts that could not be definitively identified by using SMM and incompatible according to the results with Phoenix and MALDI-TOF MS analysis. RESULTS: 603 fungal isolates including 594 Candida spp. and 9 other yeasts like species were analyzed. C. albicans was the most frequently isolated species. The results of identification by conventional methods and MALDI TOF MS were compared to the results of the Phoenix system. The observed concordance was 99.2%. The compatibility with other systems of the Phoenix system was 100%, 100%, 97.3%, 100%, and 96.9% for C. albicans, C. parapsilosis, C. tropicalis, C. glabrata, and C. krusei, respectively. CONCLUSIONS: The BD Phoenix system was found to be a simple, reliable, and effective method to identify the main species of the genus Candida in our study.

RESUMEN

BACKGROUND: Bloodstream Candida infection is a life-threatening event among ICU admitted patients. This infection is caused by a diverse range of Candida species having varied minimum inhibitory concentrations. OBJECTIVES: To identify Candida species causing bloodstream infections with their antifungal susceptibility determination. METHODS: Candida species isolated from the blood of ICU admitted patients were identified by phenotypic as well as by molecular methods including PCR-RFLP using MspI restriction enzyme and MALDI TOF MS. The minimum inhibitory concentration of fluconazole, voriconazole, amphotericin B and caspofungin was determined against isolated Candida species by CLSI M27A3 guidelines. RESULTS: A total of 119 Candida species were isolated. Among them, C. tropicalis(n=29) was the predominant isolate followed by C. parapsilosis(n=18), C. glabrata (n=12), C. krusei (n=11) and C. albicans(n=11). Uncommon Candida species isolated were; Wickerhamomyces anomalus(n=15), Kodaemia ohmeri(n=8), C. lusitaniae (n=5) and C. auris (n=2). A varied antifungal MIC values were observed. Caspofungin had the lowest MIC among the tested antifungals. Increased fluconazole MIC was observed against the isolated Candida species including C. tropicalis. All the isolated C. lusitaniae and C. auris strains have ≥1mcg/ml amphotericin B MIC. In comparison to fluconazole, voriconazole was more effective when tested in vitro. CONCLUSION: Emergence of uncommon Candida species having varied antifungal MIC warns the physicians to have a prompt, accurate identification with antifungal MIC determination in each case of bloodstream Candida infections.

RESUMEN

BACKGROUND: A large proportion of neonates are treated for presumed bacterial sepsis with broad spectrum antibiotics even though their blood cultures subsequently show no growth. This study aimed to investigate PCR-based methods to identify pathogens not detected by conventional culture. METHODS: Whole blood samples of 208 neonates with suspected early onset sepsis were tested using a panel of multiplexed bacterial PCRs targeting Streptococcus pneumoniae, Streptococcus agalactiae (GBS), Staphylococcus aureus, Streptococcus pyogenes (GAS), Enterobacteriaceae, Enterococcus faecalis, Enterococcus faecium, Ureaplasma parvum, Ureaplasma urealyticum, Mycoplasma hominis and Mycoplasma genitalium, a 16S rRNA gene broad-range PCR and a multiplexed PCR for Candida spp. RESULTS: Two-hundred and eight samples were processed. In five of those samples, organisms were detected by conventional culture; all of those were also identified by PCR. PCR detected bacteria in 91 (45%) of the 203 samples that did not show bacterial growth in culture. S. aureus, Enterobacteriaceae and S. pneumoniae were the most frequently detected pathogens. A higher bacterial load detected by PCR was correlated positively with the number of clinical signs at presentation. CONCLUSION: Real-time PCR has the potential to be a valuable additional tool for the diagnosis of neonatal sepsis.

RESUMEN

In this consensus we mainly present the etiology, epidemiology, risk factors, microbiology, clinical diagnosis and general principles of treatment, as well as the detailed diagnosis and treatment of common candidiasis. Though mucocutaneous candidiasis such as oral, esophageal and vulvovaginal infections are known as non-invasive diseases, they are included in this consensus, considering their high prevalence and the potential to be the source of systematic infections.In order to be accordant with the practical situation in China, new technologies and drugs that have not been well developed or routinely applied are not recommended in this consensus. As to the differences from foreign guidelines, we address the explanations. Individualized treatment and management should be administrated based on the specific underlying conditions, organism distribution and drug resistance profile of Candida species.
