BACKGROUND: Bismuth quadruple therapies (BQTs) including bismuth, a proton pump inhibitor (PPI) and two antibiotics have been shown to be highly effective for treating Helicobacter pylori infection even in areas of high bacterial antibiotic resistance. OBJECTIVE: To describe the time trends of use, effectiveness and safety of BQT in Europe using the European Registry on Helicobacter pylori Management (Hp-EuReg). DESIGN: Patients registered in the Hp-EuReg from 2013 to 2021 who had received BQT were included. The regimens prescribed, the number of eradication attempts, effectiveness, adherence and safety were analysed. The effectiveness was assessed by modified intention to treat (mITT). Time-trend and multivariate analyses were performed to determine variables that predicted treatment success. RESULTS: Of the 49 690 patients included in the Hp-EuReg, 15 582 (31%) had received BQT. BQT use increased from 8.6% of all treatments in 2013 to 39% in 2021. Single-capsule BQT-containing bismuth, metronidazole and tetracycline-plus a PPI (single-capsule BQT, ScBQT) was the most frequent treatment mode (43%). Schemes that obtained an effectiveness above 90% were the 10-day ScBQT and 14-day BQT using tetracycline plus metronidazole, or amoxicillin plus either clarithromycin or metronidazole. Only ScBQT achieved above 90% cure rates in all the geographical areas studied. Using the ScBQT scheme, adherence, the use of standard or high-dose PPIs, 14-day prescriptions and the use of BQT as first-line treatment were significantly associated with higher mITT effectiveness. CONCLUSION: The use of BQT increased notably in Europe over the study period. A 10-day ScBQT was the scheme that most consistently achieved optimal effectiveness. TRIAL REGISTRATION NUMBER: NCT02328131.

OBJECTIVES: To evaluate the efficacy and tolerability of a single dose of oral cefixime 800 mg plus oral doxycycline 100 mg twice a day for 7 days, compared with a recommended single dose of ceftriaxone plus single dose of oral azithromycin, for treatment of uncomplicated urogenital, rectal, or pharyngeal gonorrhoea. METHODS: A noninferiority, open-label, multicentre randomized controlled trial was conducted in Prague, Czech Republic. Some 161 patients, 18-65 years of age diagnosed with uncomplicated urogenital, rectal, or pharyngeal gonorrhoea by nucleic acid amplification test (NAAT) were randomized to treatment with single dose of cefixime 800 mg plus doxycycline 100 mg twice a day for 1 week or a single dose of ceftriaxone 1 g intramuscularly plus single dose of azithromycin 2 g. The primary outcome was the number of participants with negative culture and NAAT at 1 week and 3 weeks, respectively, after treatment initiation. RESULTS: In all, 161 patients were randomized and 152 were included in per-protocol analyses. All 76 (100%; 95% CI, 0.95-1.00) patients treated with ceftriaxone plus azithromycin achieved negative cultures and NAAT after treatment. In the cefixime plus doxycycline arm at week 1, culture was negative in all 76 (100%) patients; at week 3, culture was negative in 70 of the 76 patients (92%; 95% CI, 0.84-0.97) and NAAT negative in 66 of the 76 patients (87%; 95% CI, 0.77-0.94). At week 3, culture and NAAT were negative in 65 of the 76 patients (86%; 95% CI, 0.76-0.93). Per-protocol risk difference was 14.5%; 95% CI, 6.56-22.38. All treatment failures observed in the cefixime arm were pharyngeal gonorrhoea cases. DISCUSSION: The combination of cefixime and doxycycline did not achieve noninferiority to ceftriaxone and azithromycin for treatment of gonorrhoea when including pharyngeal gonorrhoea. It did, however, show high efficacy for urogenital and rectal gonorrhoea.

INTRODUCTION AND PURPOSE: Mycobacterium (M.) chelonae is responsible for a half of relatively rare nontuberculous mycobacteria (NTM) keratitis. We report a case of M. chelonae keratitis in a woman following sclerocorneal suture extraction after cataract surgery. RESULTS: A 70-year-old woman presented with a red eye and corneal infiltration of her left eye six weeks following sclerocorneal suture extraction after an elective cataract surgery in another institute. She complained of a sharp, cutting pain and photophobia. Since initial corneal scrapes and conjunctival swabs proved no pathogen using culture and PCR methods, non-specific antibiotics and antifungal agents were administered. As keratitis was complicated by an inflammation in the anterior chamber and vitreous, samples of the vitreous fluid were sent for microbiologic examination. DNA of Epstein-Barr virus (EBV) was repeatedly detected. Since the intrastromal abscess had formed, corneal re-scrapings were performed and M. chelonae was detected using culture, MALDI-TOF MS and PCR methods. Therapy was changed to a combination of oral and topical clarithromycin, intravitreal, topical and intracameral amikacin, and oral and topical moxifloxacin. The successful therapy led to stabilization. The optical penetrating keratoplasty was performed and no signs of the infection recurrence were found. CONCLUSIONS: The diagnosis of nontuberculous mycobacterial keratitis is difficult and often delayed. An aggressive and prolonged antimicrobial therapy should include systemic and topical antibiotics. Surgical intervention in the form of corneal transplantation may be required in the active and nonresponsive infection. In the presented case this was necessary for visual rehabilitation due to scarring.

Úvod a cíl: Infekce bakterií Helicobacter pylori (H. pylori) zůstává významným celosvětovým problémem, vč. České republiky. Cílem této studie je poskytnout přehled současných léčebných přístupů v první linii u infekce H. pylori v České republice na základě dat z Evropského registru managementu H. pylori (Hp-EuReg) a zhodnotit nejefektivnější eradikační režimy. Metodika: Hp-EuReg je mezinárodní, multicentrický registr o léčbě H. pylori, ze kterého jsme čerpali data z České republiky od roku 2019 až do ledna 2024. Tento registr shromažďuje demografická data, diagnostické postupy, předepsané eradikační režimy a výsledný efekt terapie. Pro vyhodnocení účinnosti léčby byla provedena analýza podle původního léčebného záměru (mITT). Výsledky: Do analýzy bylo zařazeno 546 pacientů ze 14 center v České republice, u kterých byla zahájena první linie terapie H. pylori. Nízké dávky inhibitorů protonové pumpy (PPI – proton pump inhibitor) (tj. 20 mg omeprazolu dvakrát denně) byly podávány u 89 % pacientů a nejčastější délka eradikačního režimu byla 14 dní (40 %). Celková účinnost první linie léčby byla 85 %. Účinnost léčby nízkými dávkami PPI (20 mg omeprazolu dvakrát denně) a vysokými dávkami PPI (80 mg omeprazolu dvakrát denně) byla 86 %, pro standardní dávku PPI (40 mg omeprazolu dvakrát denně) 82,5 %. Účinnost léčby podle délky byla pro 7denní terapii 83 %, nižší než tomu bylo u 10- a 14denní terapie, která dosáhla úspěšnosti 86 %. Nejčastěji používaným eradikačním režimem byla trojkombinace PPI, amoxicilinu a klarithromycinu u 67 % pacientů, dosahující s účinností 87 % u 7- a 14denního režimu. Optimální účinnost (>90 % dle mITT) byla dosáhnuta u 10denní sekvenční terapie a 14denní nebismutová čtyřkombinační terapie, které obě zahrnují PPI, amoxicilin, klarithromycin a metronidazol, dosahující úspěšnosti 96 % (48/50 pacientů) a 97 % (34/35 pacientů). Zbývající terapie měly účinnost nižší než 90 %, nejnižší účinnost byla dosažena u kombinace PPI, klarihtromycin a metronidazol (66 %; 35/53 pacientů). Závěr: V České republice byla celkově účinnost empirické první linie terapie suboptimální (<90 %); avšak 10denní sekvenční terapie a 14denní čtyřkombinační terapie, obě zahrnující PPI, amoxicilin, klarithromycin a metronidazol, dosáhly úspěšnosti u více než 90 % pacientů.

Background and Aim: Helicobacter pylori (H. pylori) infection remains a significant public health concern worldwide, including in the Czech Republic. The study aims to provide an overview of the current first-line treatment approaches for H. pylori infection in the Czech Republic based on data from the European Registry on H. pylori Management (Hp-EuReg), and to evaluate the most effective treatment regimens. Methods: Hp--EuReg is an international multicentric registry on the management of H. pylori, from which we extracted data from the Czech Republic from 2019 to January 2024. This registry collects demographic information, diagnostic procedures, treatment prescriptions, and outcomes for H. pylori infection management by gastroenterologists. A modified intention-to-treat (mITT) analysis was performed to evaluate the effectiveness of the treatments. Results: A total of 546 patients from 14 centres in the Czech Republic who receive first-line treatment were analysed. Low-dose (i.e.; 20 mg omeprazole equivalent twice daily) proton pump inhibitors (PPIs) were administered in 89% of patients, and the most common length of treatments was 14 days (40%). The overall mITT effectiveness of first-line treatment was 85%, obtaining 86% when prescriptions were combined either with low-dose (20 mg omeprazole equivalent twice daily), and high dose (80 mg omeprazole equivalent twice daily) PPIs, and 82.5% with standard-dose (40 mg omeprazole equivalent twice daily) PPIs. The effectiveness of 7-day prescriptions was reported to be 83%, lower than that of 10- and 14-day, both of which achieved effectiveness of 86%. The most frequently used treatment scheme was triple therapy with PPI, amoxicillin and clarithromycin, which was used in 67% of patients, reaching 87% effectiveness both with 7- and 14-day prescriptions. Optimal (>90% mITT) effectiveness was obtained with both 10-day, sequential therapy and with 14-day non-bismuth quadruple concomitant therapy including both PPI, amoxicillin, clarithromycin and metronidazole, providing 96% (48/50 patients) and 97% (34/35 patients) cure rates, respectively. The remaining therapies provided all an effectiveness lower than 90%, the lowest one obtained with PPI, clarithromycin and metronidazole (66%; 35/53 patients). Conclusions: In the Czech Republic, the first-line empirical treatment overall effectiveness was suboptimal (<90%); however, 10-day non-bismuth quadruple sequential and 14-day concomitant therapies, both composed of PPI, amoxicillin, clarithromycin and metronidazole, achieved over 90% cure rates.

Haemophilus ducreyi (HD) is an important cause of cutaneous ulcers in several endemic regions, including the Western Pacific Region, especially among children. An HD sequence typing on swab samples taken from 1,081 ulcers in the Namatanai district of Papua New Guinea, during the pilot study for treatment of yaws, has been performed using the Grant typing system. Of the 363 samples that tested positive for the 16S rDNA of HD, the dsrA sequences of 270 samples were determined. Altogether they revealed 8 HD strain types circulating in Namatanai, including seven strain types of Class I (I.3, I.4, I.5, I.9, I.10, I.11, I.12) and one strain of Class II (II.3); four Class I types (I.9, I.10, I.11, I.12) were novel. The southern region of Namatanai (Matalai Rural) was identified as the region with the lowest genotype diversity and with most infections caused by HD Class II. The middle and northern subdistricts were affected mainly by HD Class I. Analysis of patient characteristics revealed that Class II HD infections were more often represented by longer-lasting ulcers than Class I HD infections. An increase in the prevalence of the I.10 strain was found after azithromycin administration compared to the untreated population at baseline likely reflecting higher infectivity of HD Class I, and more specifically strain type I.10.

OBJECTIVES: To characterize the genetic basis of azithromycin resistance in Escherichia coli and Salmonella collected within the EU harmonized antimicrobial resistance (AMR) surveillance programme in 2014-18 and the Danish AMR surveillance programme in 2016-19. METHODS: WGS data of 1007 E. coli [165 azithromycin resistant (MIC > 16 mg/L)] and 269 Salmonella [29 azithromycin resistant (MIC > 16 mg/L)] were screened for acquired macrolide resistance genes and mutations in rplDV, 23S rRNA and acrB genes using ResFinder v4.0, AMRFinder Plus and custom scripts. Genotype-phenotype concordance was determined for all isolates. Transferability of mef(C)-mph(G)-carrying plasmids was assessed by conjugation experiments. RESULTS: mph(A), mph(B), mef(B), erm(B) and mef(C)-mph(G) were detected in E. coli and Salmonella, whereas erm(C), erm(42), ere(A) and mph(E)-msr(E) were detected in E. coli only. The presence of macrolide resistance genes, alone or in combination, was concordant with the azithromycin-resistant phenotype in 69% of isolates. Distinct mph(A) operon structures were observed in azithromycin-susceptible (n = 50) and -resistant (n = 136) isolates. mef(C)-mph(G) were detected in porcine and bovine E. coli and in porcine Salmonella enterica serovar Derby and Salmonella enterica 1,4, [5],12:i:-, flanked downstream by ISCR2 or TnAs1 and associated with IncIγ and IncFII plasmids. CONCLUSIONS: Diverse azithromycin resistance genes were detected in E. coli and Salmonella from food-producing animals and meat in Europe. Azithromycin resistance genes mef(C)-mph(G) and erm(42) appear to be emerging primarily in porcine E. coli isolates. The identification of distinct mph(A) operon structures in susceptible and resistant isolates increases the predictive power of WGS-based methods for in silico detection of azithromycin resistance in Enterobacterales.

BACKGROUND: Adherence to Helicobacter pylori (H. pylori) eradication treatment is a cornerstone for achieving adequate treatment efficacy. OBJECTIVE: To determine which factors influence compliance with treatment. METHODS: A systematic prospective non-interventional registry (Hp-EuReg) of the clinical practice of European gastroenterologists. Compliance was considered adequate if ≥90% drug intake. Data were collected until September 2021 using the AEG-REDCap e-CRF and were subjected to quality control. Modified intention-to-treat analyses were performed. Multivariate analysis carried out the factors associated with the effectiveness of treatment and compliance. RESULTS: Compliance was inadequate in 646 (1.7%) of 38,698 patients. The non-compliance rate was higher in patients prescribed longer regimens (10-, 14-days) and rescue treatments, patients with uninvestigated dyspepsia/functional dyspepsia, and patients reporting adverse effects. Prevalence of non-adherence was lower for first-line treatment than for rescue treatment (1.5% vs. 2.2%; p < 0.001). Differences in non-adherence in the three most frequent first-line treatments were shown: 1.1% with proton pump inhibitor + clarithromycin + amoxicillin; 2.3% with proton pump inhibitor clarithromycin amoxicillin metronidazole; and 1.8% with bismuth quadruple therapy. These treatments were significantly more effective in compliant than in non-compliant patients: 86% versus 44%, 90% versus 71%, and 93% versus 64%, respectively (p < 0.001). In the multivariate analysis, the variable most significantly associated with higher effectiveness was adequate compliance (odds ratio, 6.3 [95%CI, 5.2-7.7]; p < 0.001). CONCLUSIONS: Compliance with Helicobacter pylori eradication treatment is very good. Factors associated with poor compliance include uninvestigated/functional dyspepsia, rescue-treatment, prolonged treatment regimens, the presence of adverse events, and the use of non-bismuth sequential and concomitant treatment. Adequate treatment compliance was the variable most closely associated with successful eradication.

Primary ciliary dyskinesia (PCD) is a genetic disorder associated with recurrent and chronic respiratory infections due to functional defects of motile cilia. In this study, we aimed to elucidate inflammatory and proliferative responses in PCD respiratory epithelium and evaluate the effect of Azithromycin (AZT) on these responses. Airway basal cells (BCs) were isolated from nasal samples of Wild-type (WT) epitope of healthy donors and PCD donors with bi-allelic mutations in DNAH5, DNAH11 and CCDC39. Cells were expanded in vitro and stimulated with either Lipopolysaccharide (LPS) or vehicle control. Post stimulation, cells were treated with either Azithromycin (AZT) or vehicle control. Cell proliferation was imaged in real-time. Separately, BCs from the same donors were expanded and grown at an air-liquid interface (ALI) to generate a multi-ciliated epithelium (MCE). Once fully mature, cells were stimulated with LPS, AZT, LPS + AZT or vehicle control. Inflammatory profiling was performed on collected media by cytokine Luminex assay. At baseline, there was a significantly higher mean production of pro-inflammatory cytokines by CCDC39 BCs and MCEs when compared to WT, DNAH11 and DNAH5 cells. AZT inhibited production of cytokines induced by LPS in PCD cells. Differences in cell proliferation were noted in PCD and this was also corrected with AZT treatment.
