Multidrug-resistant bacterial infections are being increasingly treated in clinics with polymyxins, a class of antibiotics associated with adverse effects in the kidney, nervous system, or airways of a significant proportion of human and animal patients. Although many of the resistant pathogens display enhanced virulence, a hazard of cytotoxic interactions between polymyxin antibiotics and bacterial virulence factors (VFs) has not been assessed, to date. We report here on testing paired combinations of four Pseudomonas aeruginosa VF phenazine toxins, pyocyanin (PYO), 1-hydroxyphenazine (1-HP), phenazine-1-carboxylic acid (PCA), phenazine-1-carboxamide (PCN), and two commonly prescribed polymyxin drugs, colistimethate (CMS)/colistin and polymyxin B, in three human airway cell lines, BEAS-2B, HBE-1, and CFT-1...

BACKGROUND: Artemisia scoparia Waldst and Kit is a famous traditional Chinese medicine widely distributed in Xinjiang, China. Flavonoids extracted from it exhibits inhibitory activities against several influenza virus strains. Despite this fact, the antiviral properties of CST, one of such flavonoids, against the influenza virus has not been reported. Thus, the aim of this study is to investigate the anti-influenza virus efficacy and antiviral mechanism of CST. METHODS: The inhibitory activity of CST against influenza viruses was assessed by using viral titers and performing Western blot, qRT-PCR, and immunofluorescence assays in Madin-Darby canine kidney (MDCK) cells and a human monocytic cell line (THP-1)...

Our previous studies demonstrated that the nonstructural NV protein of infectious hematopoietic necrosis virus (IHNV) was essential for efficient viral replication and pathogenicity, and that the amino acid residues 32 EGDL35 of the NV protein were responsible for nuclear localization, and played important roles in suppressing IFN and inhibiting NF-κB activity. However, little is known about the influence of 32 EGDL35 on IHNV replication and pathogenicity. In the present study, two recombinant IHNV strains with deletions of NV 32 EGDL35 were generated and the effect on IHNV replication and pathogenicity was explored...

BACKGROUND: In people living with HIV, much is known about chronic kidney disease, defined as a glomerular filtration rate under 60mL/min. However, there is scarce data about prevalence and risk factors for milder impairment (60-89mL/min). OBJECTIVE: The present study aims to assess the influence of sex, antiretroviral therapy, and classical risk factors on the occurrence of mild decreased renal function in a large Spanish cohort of HIV-infected patients. METHODS: Cross-sectional, single center study, including all adult HIV-1-infected patients under antiretroviral treatment with at least two serum creatinine measures during 2014, describing the occurrence of and the risk factors for mildly decreased renal function (eGFR by CKD-EPI creatinine equation of 60-89mL/min)...

The catastrophic antiphospholipid syndrome (CAPS) is a life-threating variant of the antiphospholipid syndrome characterized by the development of multiple thrombosis in a short period of time, usually ending up in the failure of function of several vital organs. Most CAPS episodes are related to a prothrombotic situation or precipitating factor such as infections, surgical procedures or malignant diseases. In patients with CAPS, the development of multiple thrombosis leads to an important cytokine release that worsens the already critical patient's situation...

BACKGROUND: The prevalence of end-stage renal disease is increasing worldwide. The best treatment is kidney transplantation, although life-long immunosuppressive therapy is then mandatory. Currently, the cornerstone immunosuppressive therapy relies on tacrolimus, a calcineurin inhibitor that is nephrotoxic but whose exposition can be minimized in a delicate balance. Area covered: We addressed whether, in the setting of kidney transplantation, tacrolimus-based therapy can be tailored to medical needs: to achieve this, we searched for suitable articles in PubMed...

Invasive candidiasis is a serious pathogen of late-onset sepsis in very-low-birth- weight (VLBW) infants. Kidney is the most common organ involved and it causes morbidity and mortality, especially when fungal balls are formed. We report a 34-day-old female infant (28 weeks, 1152 gm) with systemic fungal infection complicated obstructive uropathy. On sonography, the fungal balls filled the entire pelvis without hydronephrosis. Percutaneous nephrostomy was not feasible. In addition to systemic antifungals, we successfully performed cystoscopy-assisted retrograde ureteral catheterization (RUC) to decompress the pelvis, which also provided a route for local amphotericin B irrigation to achieve therapeutic concentration without nephrotoxicity...

Interleukin-1β (IL-1β) is one of the pivotal early pro-inflammatory cytokines, which play important roles in regulating immune response and inducing a series of inflammatory reactions to infections. Interleukin-1 type I receptor (IL-1RI) is a receptor of the IL-1β that can mediate IL-1-dependent activation. In this study, partial cDNA sequences of the Pf_IL-1β and Pf_IL-1RI genes were cloned from yellow catfish (Pelteobagrus fulvidraco). The open reading frames (ORF) of Pf_IL-1β and Pf_IL-1RI genes encode putative peptides of 280 and 543 amino acids, respectively...
