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.

Amphotericin B (AmB) is one of the most effective antifungal drugs, with a strong, dose-dependent activity against most Candida and Aspergillus species responsible for life-threatening infections. However, AmB is severely toxic, which hinders its broad use. In this proof-of-concept study, we demonstrate that prodrugging AmB considerably decreases AmB toxicity without affecting its fungicidal activity. For this purpose, we modified the AmB structure by attaching a designer phosphate promoiety, thereby switching off its mode of action and preventing its toxic effects. The original fungicidal activity of AmB was then restored upon prodrug activation by host plasma enzymes. These AmB prodrugs showed a safer toxicity profile than commercial AmB deoxycholate in Candida and Aspergillus species and significantly prolonged larval survival of infected Galleria mellonella larvae. Based on these findings, prodrugging toxic antifungals may be a viable strategy for broadening the antifungal arsenal, opening up opportunities for targeted prodrug design.

INTRODUCTION: SARS-CoV-2 respiratory infection is associated with significant morbidity and mortality, especially in hospitalized high-risk patients. We aimed to evaluate the effects of treatment options (vitamin D, anticoagulation, isoprinosine, ivermectin) on hospital mortality in non-vaccinated patients during the 2021 spring wave in the Czech Republic. METHODS: Initially, 991 patients hospitalized in the period January 1, 2021, to March 31, 2021, with PCR-confirmed SARS-CoV-2 acute respiratory infection in two university and five rural hospitals were included in the study. After exclusion of patients with an unknown outcome, a total of 790 patients entered the final analysis. The effects of different treatments were assessed in this cohort by means of propensity score matching. RESULTS: Of the 790 patients, 282 patients died in the hospital; 37.7% were male and 33.3% were female. Age, sex, state of the disease, pneumonia, therapy, and several comorbidities were matched to simulate a case-control study. For anticoagulation treatment, 233 cases (full-dose) vs. 233 controls (prophylactic dose) were matched. The difference in mortality was significant in 16 of the 50 runs. For the treatment with isoprinosine, ivermectin, and vitamin D, none of the 50 runs led to a significant difference in hospital mortality. CONCLUSION: Prophylactic-dose anticoagulation treatment in our study was found to be beneficial in comparison with the full dose. Supplementation with vitamin D did not show any meaningful benefit in terms of lowering the hospital mortality. Neither ivermectin nor, isoprinosine was found to significantly decrease hospital mortality.

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.

The current global scenario presents us with a growing increase in infections caused by fungi, referred to by specialists in the field as a "silent epidemic", aggravated by the limited pharmacological arsenal and increasing resistance to this therapy. For this reason, drug repositioning and therapeutic compound combinations are promising strategies to mitigate this serious problem. In this context, this study investigates the antifungal activity of the non-toxic, low-cost and widely available cationic polyelectrolyte Poly(diallyldimethylammonium chloride) (PDDA), in combination with different antifungal drugs: systemic (amphotericin B, AMB), topical (clioquinol, CLIO) and oral (nitroxoline, NTX). For each combination, different drug:PDDA ratios were tested and, through the broth microdilution technique, the minimum inhibitory concentration (MIC) of these drugs in the different ratios against clinically important Candida species strains was determined. Overall, PDDA combinations with the studied drugs demonstrated a significant increase in drug activity against most strains, reaching MIC reductions of up to 512 fold for the fluconazole resistant Candida krusei (Pichia kudriavzevii). In particular, the AMB-PDDA combination 1:99 was highly effective against AMB-resistant strains, demonstrating the excellent profile of PDDA as an adjuvant/association in novel antifungal formulations with outdated conventional drugs.

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.
