Two cases of monomicrobial intraabdominal abscesses due to KPC - 3 Klebsiella pneumoniaeST258 clone
2011
Abstract Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection…
Role of microglia in blood pressure and respiratory responses to acute hypoxic exposure in rats
2021
AbstractMicroglia modulate cardiorespiratory activities during chronic hypoxia. It has not been clarified whether microglia are involved in the cardiorespiratory responses to acute hypoxia. Here we investigated this issue by comparing cardiorespiratory responses to two levels of acute hypoxia (13% O2 for 4 min and 7% O2 for 5 min) in conscious unrestrained rats before and after systemic injection of minocycline (MINO), an inhibitor of microglia activation. MINO increased blood pressure but not lung ventilation in the control normoxic condition. Acute hypoxia stimulated cardiorespiratory responses in MINO-untreated rats. MINO failed to significantly affect the magnitude of hypoxia-induced bl…
Treatment of human brucellosis with rifampin plus minocycline
2003
In order to evaluate the efficacy and tolerability of a high intravenous dose of rifampin plus oral minocycline (administered daily for 3 weeks) for the treatment of acute brucellosis, we retrospectively reviewed the outcome of 239 consecutive patients (135 adults and 104 children) diagnosed and treated over a 17-year period in Italy. The combination used resulted in 100% response and a relapse rate lower than 2%. Fifty-two (30 adults and 22 children) (29.8%) complained of mild adverse effects including an increase in aspartate aminotransferase (>250 IU) observed in 12 cases and considered related to rifampin and in 11 cases a reversible hyperpigmentation of the tongue attributed to minocyc…

Cetuximab-induced skin exanthema: Improvement by a reactive skin therapy
2010
More than 80% of patients treated with cetuximab develop an acneiform follicular skin exanthema. Grade 3 exanthema develops in 9-19% of these cases, bearing the risk of cetuximab dose-reduction or cessation. We retrospectively analysed a cohort of 20 patients treated with cetuximab and an in-house reactive skin protocol upon development of an exanthema. The reactive skin protocol was built up as follows: grade 1 exanthema: topical cleansing syndet (Dermowas®) + topical metronidazole cream (Rosiced®); grade 2 exanthema: grade 1 treatment + oral minocycline 50 mg twice per day; grade 3 exanthema: grade 2 treatment + topical corticoid (Dermatop®) + topical nadifloxacin (Nadixa®). As soon as a …
Reversible neural stem cell niche dysfunction in a model of multiple sclerosis
2011
Objective The subventricular zone (SVZ) of the brain constitutes a niche for neural stem and progenitor cells that can initiate repair after central nervous system (CNS) injury. In a relapsing-remitting model of experimental autoimmune encephalomyelitis (EAE), the neural stem cells (NSCs) become activated and initiate regeneration during acute disease, but lose this ability during the chronic phases of disease. We hypothesized that chronic microglia activation contributes to the failure of the NSC repair potential in the SVZ. Methods Using bromodeoxyuridine injections at different time points during EAE, we quantified the number of proliferating and differentiating progenitors, and evaluate…
Erratum to: Cetuximab-induced skin exanthema: prophylactic and reactive skin therapy are equally effective
2013
Purpose Treatment with cetuximab is accompanied by the development of an acneiform follicular skin exanthema in more than 80 % of patients. Severe exanthema (grade III/IV) develops in about 9–19 % of patients with the necessity of cetuximab dose reduction or cessation. Methods The study presented was a retrospective analysis of 50 gastrointestinal cancer patients treated with cetuximab in combination with either FOLFIRI or FOLFOX. One cohort of 15 patients received an in-house reactive skin protocol upon development of an exanthema. A second cohort of 15 patients received a skin prophylaxis starting with the first dose of cetuximab before clinical signs of toxicity. A third historic group o…
Antibiotic susceptibility of cocultures in polymicrobial infections such as peri-implantitis or periodontitis: an in vitro model.
2011
Although polymicrobial infections, such as peri-implantitis or periodontitis, were postulated in the literature to be caused by synergistic effects of bacteria, these effects remain unclear looking at antibiotic susceptibility. The aim of this study is to compare the antibiotic susceptibilities of pure cultures and definite cocultures.Laboratory strains of Aggregatibacter actinomycetemcomitans (Aa) (previously Actinobacillus actinomycetemcomitans), Capnocytophaga ochracea (Co), and Parvimonas micra (Pm) (previously Peptostreptococcus micros) were cultivated under anaerobic conditions, and their susceptibilities to 10 antibiotics (benzylpenicillin G, ampicillin, amoxicillin, ampicillin/sulba…
No findings of dental defects in children treated with minocycline
2004
Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…
Cardiac safety and potential efficacy: two reasons for considering minocycline in place of azithromycin in COVID-19 management
2020
Currently, there is no effective therapy for COVID-19, and several approaches are under investigation. Nevertheless, some drugs are used off-label despite the absence of clear data on their effectiveness. Among these, hydroxychloroquine suppresses SARS-CoV-2 replication in vitro,1 and clinical trials are ongoing to evaluate its use as an anti-COVID-19 agent. To date, the FDA and EMA allow its use only in hospitalized patients with severe COVID-19 or in those at high risk, in cases where other trials are not feasible. According to a small non-randomized study, hydroxychloroquine’s efficacy might be enhanced by azithromycin, as the combination of these two drugs appeared to accelerate viral c…
