Abstract

Acute mastoiditis is a well-known complication of acute otitis media in children. Last year we noticed some changes: more virulent pathogens, a more fulminant course of the disease and an increased need for surgical treatment in children with acute mastoiditis admitted to our hospital. Recently, other authors have raised the same concerns. Based on the last 12 consecutive cases of pediatric acute mastoiditis admitted to our hospital and a review of recent literature, we discuss a possible change in presentation, complication rate and microbiology in order to raise vigilance to a possibly changing pathology.

Abstract

We investigated the phenotype and functional capacities of tumour-infiltrating lymphocytes (TIL), freshly isolated from primary renal cell carcinoma (RCC) specimens (n=20). Three-colour flow cytometry immunophenotyping revealed that RCC TIL consist mainly of CD3(+) T cells, with a clear predominance of CD4(-)CD8(+) over CD4(+) CD8(-) T cells, and a marked population of CD4(+) CD8(+) T cells. Natural killer (NK) cells were also strongly represented (> 25% in 15 of 20 tumour samples), while B cells constituted a minor TIL subset (<5% in 18 of 20 tumour samples). More importantly, the T and NK cells within the tumour displayed a significantly higher expression of the early activation marker CD69 than their counterparts in adjacent normal renal tissue and in peripheral blood. Expression of CD54 and of HLA-DR was also elevated on CD3(+) TIL, and HLA-DR expression was further vigorously up-regulated following ex vivo stimulation with anti-CD3, all suggesting enhanced immune activity within the tumour microenvironment. CD3(+) CD4(+) TIL displayed a normal capacity to up-regulate CD25 expression and to secrete both Th1-type (IL-2, tumour necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma)) and Th2-type (IL-4, IL-5 and IL-10) cytokines upon triggering with anti-CD3. Furthermore, cytokine production was susceptible to modulation by CD28 costimulation. CD3(+) CD8(+) TIL, on the other hand, consistently demonstrated a poor up-regulation of CD25 upon triggering with anti-CD3, and displayed poor ex vivo cytolytic activity in an anti-CD3-redirected 4-h cytotoxicity assay against murine P815 cells. Collectively, our findings indicate that the CD3(+) CD4(+) TIL in RCC have normal functional capacities, whereas the proportionally major CD3(+) CD8(+) TIL are functionally impaired. The relevance of these findings to the in vivo local immune response in RCC is discussed.

31. Evaluation of Copan FLOQSwab for the molecular detection of Chlamydia trachomatisby Abbott RealTime CT PCR

Author

Coorevits, L., Vanscheeuwijck, C., Traen, A., Bingé, L., Ryckaert, I., and Padalko, E.

Abstract

Objectives: We evaluated Copan FLOQSwabs next to Abbott swabs for the detection of Chlamydia trachomatis(CT) by Abbott RealTime PCR.Methods: We collected 1062 paired swabs from female sex workers. The study was divided in two arms, according to the order of swab collection.Results: If the Abbott swab was collected first, 501 couples were concordant and two discordant (Abbott negative and Copan positive). If the Copan swab was collected first, 537 couples were concordant and 10 discordant (eight Abbott negative and Copan positive and two Abbott positive and Copan negative). All discordant samples contained low levels of C. trachomatis. Technical issues lead to retesting of 64 Copan and 21 Abbott swabs.Conclusion: Our results show that Copan FLOQSwabs can be used interchangeably with Abbott swabs. While appearing to have an advantage in detecting more positive samples, the use of Copan swabs led to a higher retesting rate due to technical errors.

33. Breakthrough Saprochaete capitata infections in patients receiving echinocandins: case report and review of the literature.

Author

Abstract

We report a rare case of a fatal Saprochaete capitata breakthrough infection in a patient with acute myeloid leukemia receiving empirical caspofungin therapy. S. capitata is an uncommon, yet emerging cause of invasive infections, especially in patients with haematological malignancies. Blood cultures from our patient yielded S. capitata which was found to be resistant, in vitro, to caspofungin. We consecutively reviewed all published cases of breakthrough infections caused by S. capitata in patients receiving echinocandins. S. capitata should be considered in those patients who remain febrile or who develop invasive mould infections while under echinocandin therapy. [ABSTRACT FROM AUTHOR]

Abstract

CD14 is a differentiation-stage-linked glycosyl-phophatidyl-inositol-linked glycoprotein on human peripheral blood monocytes and tissue macrophages, which functions as a receptor for lipopolysaccharide. Here, the effects of granulocyte-macrophage colony-stimulating factor (GMCSF), a cytokine with proliferation- and differentiation-inducing properties on myeloid lineage cells, were studied on CD14 expression by peripheral blood cells. GM-CSF down-regulated the membrane expression of CD14 on monocytes, while it up-regulated expression on neutrophils. GM-CSF also decreased the spontaneous release of CD14 in monocyte culture supernatants. Down-regulation of CD14 expression and release was accompanied by a decrease in the mRNA transcript for CD14, suggesting that it most likely reflects an effect on the transcriptional level. The functional significance of this phenomenon, and its potential relation to the terminal differentiation of monocytes, are discussed. [ABSTRACT FROM AUTHOR]

35. B7-CD28 interaction is a late acting co-stimulatory signal for human T cell responses.

Author

Abstract

The interaction of CD28 with one of the B7 molecules (CD80 and CD86) on professional antigen-presenting cells (APC) is generally considered as the most important co-stimulatory signal for T cell activation. APC in a resting condition express either no or only low levels of B7 molecules. These are up-regulated as a result of interactions with activated T cells, thus suggesting that B7-CD28 interaction is not required at initiation of T cell activation. To study this issue, we blocked B7-CD28 interaction at various time points after in vitro stimulation of peripheral blood T cells with allogeneic monocytes. Epstein-Barr virus-transformed B cells or soluble antigens. We observed that T cell proliferation and IL-2 production were inhibited by B7-blocking agents (CTLA-4-Ig or anti-B7 mAb) almost to the same degree when added either at initiation of culture or 24 h later. B7-blocking agents still resulted in significant inhibition of allogeneic T cell activation when added after 48 h. Furthermore, when CTLA-4-Ig was added at the start of an allogeneic T cell stimulation, addition of anti-CD28 mAb after 24 h of culture nearly fully restored T cell proliferation to control levels. Finally, we demonstrate that delayed addition of B7-blocking agents together with cyclosporin A 1 day after the onset of culture of T cells with allogeneic B cells is highly efficient to induce energy as evaluated by lack of proliferation, cytotoxic T lymphocyte reactivity and IFN-gamma or IL-5 production upon alloantigen rechallenge. Taken together, our data can explain why B7 expression on APC is not required at the time of initial APC-T cell contact, and suggest that the effect of the CD28 signal indeed consists in prolonging IL-2 production and amplifying T cell responses, rather than in providing a critical co-stimulatory signal at the time of initial TCR triggering.

Abstract

Objectives: Sexually transmitted infections (STIs) are a global cause of acute illness. Early detection plays a crucial role in interrupting transmission and preventing complications. However, the accessibility of STI testing is curbed by the lack of an overall preferred sample type. By means of a prospective study in female sex workers (FSW), we compared the sensitivity of samples from different anatomical sites in detecting Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Mycoplasma genitalium and human papillomavirus. Besides, we documented the prevalence of each STI in this high-risk population. Methods: We selected 303 FSW and tested them for each STI by nucleic acid amplification testing on two vaginal and cervical swabs from different manufacturers, cervical smear and first-void urine. The sensitivity of each sample type was compared for each infectious agent in order to identify a consensus sample type. Results: Vaginal swabs were superior to all other sample types, with an overall sensitivity of 86%. The sensitivity was the lowest for first-void urine, detecting only 63% of positive cases. The prevalence was 3.3% (10/299) for Neisseria gonorrhoeae; 9.0% (27/299) for Chlamydia trachomatis; 7.4% (22/298) for Trichomonas vaginalis; 10.8% (32/296) for Mycoplasma genitalium and 55.6% (158/284) for human papillomavirus. Conclusions: When testing for STIs, vaginal swabs are the sample of choice and first-void urine should be avoided. Designating (self-sampled) vaginal swabs as a consensus sample type enables harmonization of STI testing and extension of testing to large numbers of unscreened females.

Abstract

Background: Polyethylene glycol (PEG) and polysorbate 80 (PS80) allergy preclude from SARS-CoV-2 vaccination. The mechanism(s) governing cross-reactivity and PEG molecular weight dependence remain unclear., Objectives: To evaluate PEGylated lipid nanoparticle (LNP) vaccine (BNT162b2) tolerance and explore the mechanism of reactivity in PEG and/or PS80 allergic patients., Methods: PEG/PS80 dual- (n = 3), PEG mono- (n = 7), and PS80 mono-allergic patients (n = 2) were included. Tolerability of graded vaccine challenges was assessed. Basophil activation testing on whole blood (wb-BAT) or passively sensitized donor basophils (allo-BAT) was performed using PEG, PS80, BNT162b2, and PEGylated lipids (ALC-0159). Serum PEG-specific IgE was measured in patients (n = 10) and controls (n = 15)., Results: Graded BNT162b2 challenge in dual- and PEG mono-allergic patients (n = 3/group) was well tolerated and induced anti-spike IgG seroconversion. PS80 mono-allergic patients (n = 2/2) tolerated single-dose BNT162b2 vaccination. Wb-BAT reactivity to PEG-containing antigens was observed in dual- (n = 3/3) and PEG mono- (n = 2/3), but absent in PS80 mono-allergic patients (n = 0/2). BNT162b2 elicited the highest in vitro reactivity. BNT162b2 reactivity was IgE mediated, complement independent, and inhibited in allo-BAT by preincubation with short PEG motifs, or detergent-induced LNP degradation. PEG-specific IgE was only detectable in dual-allergic (n = 3/3) and PEG mono-allergic (n = 1/6) serum., Conclusion: PEG and PS80 cross-reactivity is determined by IgE recognizing short PEG motifs, whereas PS80 mono-allergy is PEG-independent. PS80 skin test positivity in PEG allergics was associated with a severe and persistent phenotype, higher serum PEG-specific IgE levels, and enhanced BAT reactivity. Spherical PEG exposure via LNP enhances BAT sensitivity through increased avidity. All PEG and/or PS80 excipient allergic patients can safely receive SARS-CoV-2 vaccines., (Copyright © 2023 The Authors. Published by Elsevier Inc. All rights reserved.)

Abstract

Objectives: To evaluate the analytical performance of the TB-IGRA® assay on the VIDAS3 platform (bioMérieux) when testing a predominantly low risk population in a low incidence area., Results: Eighty-eight percent of the results were concordant between QuantiFERON®-TB Gold-Plus (QFT®-Plus, QIAGEN) and TB-IGRA®. All 12 of 99 (12.1%) discordant results were determined positive only with the TB-IGRA® assay. In 11 of 12 of these discordant cases, no explanation could be found in the medical record. Five of these discrepant results were probably caused by the use of contaminated stimulation reagents. The remaining 6 discrepant samples were also part of the reproducibility experiment and only 2 results were reproducible positive. Overall, in the reproducibility experiment 5 of 25 (20.0 %) results were not repeatable., Conclusions: the TB-IGRA® assay seems prone to contamination. Besides, we documented a reproducibility of only 80.0% with the TB-IGRA® assay., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

42. Alpha-amylase as the culprit in an occupational mealworm allergy case.

Author

Abstract

Background: Occupational allergy has been described in employees working in contact with mealworms in pet stores, live fish bait or infested stored grains and recently, in mealworm farming for animal feed and human consumption. Mealworm allergens linked to occupational allergy are troponin C, cockroach-like allergen, tropomyosin, arginine kinase, early-staged encapsulation inducing- and larval cuticle proteins., Objective: We report a case of occupational mealworm allergy and studied the culprit component., Methods: Diagnosis was done by skin prick, specific IgE, basophil activation and lung function testing. Allergen purification was performed by anion-exchange chromatography and immunoblotting with patient IgE. Allergens were identified by in-gel trypsin digest and tandem mass spectrometry. Allergenicity and specificity further confirmed by IgE inhibition and passive basophil activation experiments., Results: We describe a new case of occupational mealworm allergy in a laboratory worker, with sensitization to different developmental stages and derivates of the mealworm. In basophil activation tests, the majority of patient's basophils (69%-91%) degranulated upon stimulation with the lowest concentration of mealworm extracts (0.16 µg/ml). Despite strong sensitization to mites, the patient did not show cross-reactivity to other insects. We were able to identify alpha-amylase as the main allergen and through inhibition experiments, we demonstrated that low amounts (0.1 µg/ml) of this allergen could strongly inhibit mealworm specific IgE by 79.1%. Moreover, passive BAT experiments demonstrated the IgE-alpha-amylase interaction to be functional, inducing up to 25.5% degranulation in healthy donor basophils., Conclusion: Alpha-amylase can be identified as the responsible allergen in this specific case of occupational mealworm allergy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Ganseman, Ieven, Frans, Coorevits, Pörtner, Martens, Bullens, Schrijvers, Breynaert and Proost.)

Abstract

Introduction: The high variability of SARS-CoV-2 serological response after COVID-19 infection hampers its use as indicator of the timing of infection. A potential alternative method is the determination of affinity maturation of SARS-CoV-2 IgG, expressed as the SARS-CoV-2 IgG avidity., Methods: SARS-CoV-2 IgG concentration and avidity were measured in sera of hospitalized COVID-19 patients sampled at two weeks and ≥12 weeks post symptom onset using an in-house developed protocol based on EUROIMMUN (anti-spike) and EDI™ (anti-nucleocapsid) SARS-CoV-2 IgG ELISA protocols., Results: We included 68 confirmed COVID-19 patients that tested positive for SARS-CoV-2 IgG in both the initial and follow-up specimen sampled at a median of 14 (range 10-18) days and 120 (range 84-189) days, respectively, post symptom onset. The median anti-spike and anti-nucleocapsid SARS-CoV-2 IgG avidity response was 40% (range 9-93%) and 72% (range 27-104%), respectively, for the first sample, and 66% (range 28-90%) and 57% (range 25-94%), respectively, for the second sample. The proportion of SARS-CoV-2 IgG avidity results ≥60% was significantly lower for anti-spike compared to anti-nucleocapsid IgG for initial samples ( p < 0.01) and vice versa for follow-up samples ( p < 0.01)., Conclusion: Anti-nucleocapsid SARS-CoV-2 IgG maturation occurs faster and avidity decreases faster than anti-spike IgG, indicating different kinetics of anti-spike and anti-nucleocapsid IgG. Further, affinity maturation after SARS-CoV-2 infection is frequently incomplete.

Abstract

Background: Over the last few years, studies have shown that the majority of egg allergic children tolerate baked egg (e.g., cake), and that consuming baked egg accelerates the resolution of egg allergy. However, few prospective studies demonstrate the step-wise reintroduction of egg at home after developing baked egg tolerance. Although this could have a positive impact on the children's quality of life and nutrition. Additionally, research supporting the theoretical concept that heating in the presence or absence of wheat causes reduced allergenicity of egg proteins is limited., Objective: To investigate the clinically most favorable duration of gradual egg-tolerance induction in baked egg tolerant children at home, with regard to complete raw egg tolerance., Methods: Baked egg tolerant children above 12 months of age were randomly assigned to a short- or long arm protocol. In the short arm, egg-tolerance induction was studied over 18 months compared to 30 months in the long arm. Children were guided through this protocol involving the step-wise introduction of increasingly allergenic forms of egg starting with baked egg offered as cake, followed by hard-boiled egg, omelet/waffle/pancake, soft-boiled egg, and finally raw egg. We hereby designed this protocol based on the influence of thermal processing in the presence or absence of wheat on egg proteins, as investigated by ELISA, SDS-PAGE, and immunoblotting. At inclusion, children either passed an in-hospital cake challenge or had ovomucoid sIgE ≤1.2 kUA/L, which was considered safe for introduction at home., Results: Gel electrophoresis revealed that the ovalbumin band became weaker with heating, while the ovomucoid band remained stable. In accordance, the IgE-binding to ovalbumin decreased with extensive heating, as opposed to ovomucoid. However, heating in the presence of wheat led to a decreased IgE reactivity to ovomucoid. Of the 78 children in the intention-to-treat group, 39 were randomized to each arm. Fifty-eight children reached the raw egg tolerance endpoint, of which 80% were in the short arm and 69% in the long arm. Within the short arm, the median time to raw egg tolerance was 24 months (95% CI, 21-27 months) compared to 30 months (95% CI, 28-32 months) in the long arm ( p = 0.005). No grade IV reactions or cases of eosinophilic esophagitis were observed. The short arm was considered to be non-inferior to the long arm., Conclusion: Our gradual short arm protocol appears to be safe and allows clinicians to guide baked egg tolerant children toward raw egg tolerance at home. The allergenicity of the egg proteins was affected by heating temperature and duration, as well as the presence of wheat., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 De Vlieger, Nuyttens, Matton, Diels, Verelst, Leus, Coppens, Sauer, Dilissen, Coorevits, Matthys, Schrijvers, Raes and Bullens.)

Abstract

Background: Molecular detection of SARS-CoV-2 in respiratory samples is the gold standard for COVID-19 diagnosis but it has a long turnaround time and struggles to detect low viral loads. Serology could help to diagnose suspected cases which lack molecular confirmation. Two case reports are presented as illustration., Objectives: The aim of this study was to evaluate the performance of several commercial assays for COVID-19 serology. We illustrated the added value of COVID-19 serology testing in suspect COVID-19 cases with negative molecular test., Study Design: Twenty-three sera from 7 patients with a confirmed molecular diagnosis of SARS-CoV-2 were tested using 14 commercial assays. Additionally, 10 pre-pandemic sera and 9 potentially cross-reactive sera were selected. We calculated sensitivity and specificity. Furthermore, we discuss the diagnostic relevance of COVID-19 serology in a retrospective cohort of 145 COVID-19 cases in which repetitive molecular and serological SARS-CoV-2 tests were applied., Results: The interpretation of the pooled sensitivity of IgM/A and IgG resulted in the highest values (range 14-71% on day 2-7; 88-94% on day 8-18). Overall, the specificity of the assays was high (range 79-100%). Among 145 retrospective cases, 3 cases (2%) remained negative after sequential molecular testing but positive on final SARS-CoV-2 serology., Conclusion: Sensitivity of COVID-19 serological diagnosis was variable but consistently increased at >7 days after symptom onset. Specificity was high. Our data suggest that serology can complement molecular testing for diagnosis of COVID-19, especially for patients presenting the 2 nd week after symptom onset or later.

Abstract

Objective: To reduce the inappropriate use of broad-spectrum antibiotics in a 1000+ bed acute tertiary care hospital by the introduction of cascade antimicrobial susceptibility reporting for Enterobacterales., Methods: Over a 1-year period, we selectively suppressed reporting of susceptibility to the broad-spectrum antibiotics piperacillin-tazobactam (TZP) and meropenem (MEM) for Enterobacterales strains susceptible to amoxicillin-clavulanic acid (AMC) and negative for extended-spectrum β-lactamase (ESBL). We measured the effects on hospital-wide antibiotic consumption (defined daily doses/1000 admissions) and resistance of Escherichia coli and Klebsiella pneumoniae on two levels. First, we compared resistance and antibiotic use for the antibiotics impacted by the intervention (AMC, TZP and MEM) with control antibiotics that were consistently reported (fluoroquinolones, trimethoprim-sulfamethoxazole and third-generation cephalosporins). Second, we compared the resistance for TZP and MEM with a control pathogen ( Pseudomonas aeruginosa ) and studied the impact on rate of Clostridioides difficile -associated diarrhoea in our hospital., Results: We observed an overall increased use of AMC relative to overall antibiotic consumption (20.0%, p<0.0001) together with a decreased use of TZP (-11.9%, p=0.049) and unchanged use of MEM (p=0.68) relative to overall antibiotic consumption. As for resistance, the number of ESBL-positive K. pneumoniae strains diminished by 5.9% (p<0.0001). When focusing on intensive care units, the carbapenemase-producing Enterobacterales (CPE) rate also decreased by 4.5% (p=0.0091). For E. coli , no significant difference in ESBL (p=0.33) and CPE (p=0.48) rates were observed. No significant difference in the rate of C. difficile infections was observed (p=0.40)., Conclusions: Restricted susceptibility reporting of TZP and MEM was associated with a significant increased use of AMC and decreased use of TZP relative to overall antibiotic consumption and significant reduction in ESBL- and CPE-positive K. pneumoniae strains., Competing Interests: Competing interests: JDW: grant from the Flanders Research Foundation during the conduct of the study (Senior Clinical Investigator Grant); consulted for Accelerate, Bayer Healthcare, Cubist, Grifols, MSD and Pfizer (honoraria were paid to his institution)., (© European Association of Hospital Pharmacists 2022.

Abstract

Background: Early 2020, a COVID-19 epidemic became a public health emergency of international concern. To address this pandemic broad testing with an easy, comfortable and reliable testing method is of utmost concern. Nasopharyngeal (NP) swab sampling is the reference method though hampered by international supply shortages. A new oropharyngeal/nasal (OP/N) sampling method was investigated using the more readily available throat swab., Results: 35 patients were diagnosed with SARS-CoV-2 by means of either NP or OP/N sampling. The paired swabs were both positive in 31 patients. The one patient who tested negative on both NP and OP/N swab on admission, was ultimately diagnosed on bronchoalveolar lavage fluid. A strong correlation was found between the viral RNA loads of the paired swabs (r = 0.76; P < 0.05). The sensitivity of NP and OP/N analysis in hospitalized patients (n = 28) was 89.3% and 92.7% respectively., Conclusions: This study demonstrates equivalence of NP and OP/N sampling for detection of SARS-CoV-2 by means of rRT-PCR. Sensitivity of both NP and OP/N sampling is very high in hospitalized patients.

Abstract

Objectives: As Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are the most commonly reported STIs in Belgium and the majority of women infected are asymptomatic, targeted screening of patients in specified risk groups is indicated. To prevent long-term complications and interrupt transmission, extragenital samples should be included. As this comes with a substantial extra cost, analysis of a pooled sample from vaginal and extragenital sites could be a solution. In this study, we evaluated the feasibility of molecular testing for CT and NG in pooled versus single-site samples in a large cohort of female sex workers., Methods: Women were sampled from three anatomical sites: a pharyngeal, a vaginal and a rectal swab. Each sample was vortexed, and 400 µL of transport medium from each sample site was pooled into an empty tube. NAAT was performed using the Abbott RealTime CT/NG assay on the m2000sp/rt system., Results: We included 489 patients: 5.1% were positive for CT; 2.0% were positive for NG and 1.4% were coinfected, resulting in an overall prevalence of 6.5% (95% CI 4.5% to 9.1%) for CT and 3.5% (95% CI 2.0% to 5.5%) for NG. From the 42 patients positive on at least one non-pooled sample, only 5 gave a negative result on the pooled sample, resulting in a sensitivity of 94% (95% CI 79% to 99%) for CT and 82% (95% CI 57% to 96%) for NG. The missed pooled samples were all derived from single-site infections with low bacterial loads. The possibility of inadequate self-sampling as a cause of false negativity was excluded, as 4/5 were collected by the physician. Testing only vaginal samples would have led to missing 40% of CT infections and 60% of NG infections., Conclusions: Pooling of samples is a cost-saving strategy for the detection of CT and NG in women, with minimal decrease in sensitivity. By reducing costs, more patients and more extragenital samples can be tested, resulting in higher detection rates., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

49. Tintelnotia destructans as an emerging opportunistic pathogen: First case of T. destructans superinfection in herpetic keratitis.

Author

Roels D, Coorevits L, and Lagrou K

Abstract

Purpose: Only recently Tintelnotia was described as a new genus in the Phaeosphaeriaceae family of fungi containing two species, T. opuntiae and T. destructans . Until now, T. destructans keratitis was associated with contact lens wear and ocular trauma. We present the first case of T. destructans keratomycosis presenting as a superinfection in herpetic keratitis., Observations: We present a case of a 53-year-old woman who presented with a unilateral keratitis since 3 weeks without history of trauma or contact lens wear, not responding to topical ofloxacin. Polymerase Chain Reaction (PCR) of the corneal ulcer was positive for Herpes Simplex Virus type 1 (HSV-1). Signs and symptoms progressively improved after starting topical and systemic antiviral therapy. Six weeks later however, our patient presented with a new white infiltrate in the previous herpetic epithelial defect. In vivo confocal microscopy showed fungal hyphae and culture from corneal scrapings identified a hyphomycete. Intensive antimycotic therapy could not prevent a corneal perforation 1 week later. Penetrating keratoplasty was performed with intracameral injection of amphotericin B. Culture of the corneal button and PCR and sequence analysis on the fungal isolate confirmed the diagnosis of T. destructans keratomycosis. Six months after penetrating keratoplasty, biomicroscopy showed a clear graft without recurrence of fungal activity., Conclusions and Importance: T. destructans is an emerging opportunistic pathogen causing severe keratomycosis. Despite intensive antimycotic therapy, rapid progression to corneal perforation can be seen. Early diagnosis using confocal microscopy, fungal culture and PCR can allow prompt initiation of treatment, which should be guided by in vitro susceptibility testing., Competing Interests: The authors declare that they have no conflicts of interest., (© 2020 The Authors.)

Abstract

In this report we evaluated a diagnostic algorithm, proposed by the Belgian Superior Health Council, to detect acute and past Epstein-Barr virus (EBV) infections by means of serology in donors of human body material for transplantation. The available EBV serology parameters were tested on eighty serum samples on three random access analysers: Architect i2000 SR, Liasion XL and BioPlex 2200. The EBV sero-status was determined according to the proposed algorithm and results were compared between the different analysers. Seventy one % of the samples gave concordant interpretations on the three analysers. Most of the discordant results were attributable to early antigen (EA) IgG. The knowledge of the EA IgG and heterophile antibodies (HA) IgM status provided only limited added value and was only useful to distinguish between a very early acute infection and false positivity of viral capsid antigen IgM. The diagnostic algorithm proposed by the Belgian Superior Health Council is merely directive and each individual lab remains responsible for the interpretation and implementation of test combinations for the detection of EBV infections. Our study shows the limited added value of testing for EA IgG and HA IgM, based both on clinical and technical performance.
