Ferritin (Ftn), a globular protein, sequesters 4500 atoms of iron per molecule. Elevated serum Ftn levels (hyperferritinemia) is an indicator of iron homeostasis disorders. We present the results of an observational study involving 17 patients with hyperferritinemia unrelated to hereditary hemochromatosis (HH). All participants received treatment with 200 mg of bovine lactoferrin (bLf) once ( n  = 14) or twice ( n  = 3) a day before meals. The patients, treated with 200 mg/day of bLf, exhibited a significant increase in red blood cells (+10%, p  < 0.001), hemoglobin (+4%, p  < 0.001), and hematocrit (+15%, p  = 0.004), accompanied by a significant reduction in serum Ftn levels (-52%, p  < 0.001), C-reactive protein (CRP) (-85.0%, p  < 0.001), and D-dimers (-19%, p  < 0.001). Among the three patients treated with 400 mg/day of bLf, two had effects similar to those of patients bLf-treated with 200 mg/day and one experienced a strong reduction of Ftn, CRP, and erythrocyte sedimentation rate (from -97% to -75%). The decrease in serum Ftn levels due to bLf treatment was largely independent of gender ( p  = 0.78), age ( p  = 0.66), baseline symptoms ( p  = 0.20), and concomitant acute ( p  = 0.34) and chronic ( p  = 0.53) infections. Although this observational pilot study yields positive effects in patients with hyperferritinemia unrelated to HH treated with bLf, a larger sample size is needed for conclusive results., Competing Interests: Anna Maria Costanzo is an employee of Pharmaguida s.r.l.

Uropathogenic Escherichia coli (UPEC) strains are the primary cause of urinary tract infections (UTIs). UPEC strains are able to invade, multiply and persisting in host cells. Therefore, UPEC strains are associated to recurrent UTIs requiring long-term antibiotic therapy. However, this therapy is suboptimal due to the increase of multidrug-resistant UPEC. The use of non-antibiotic treatments for managing UTIs is required. Among these, bovine lactoferrin (bLf), a multifunctional cationic glycoprotein, could be a promising tool because inhibits the entry into the host cells of several intracellular bacteria. Here, we demonstrate that 100 μg/ml bLf hinders the invasion of 2.0 ± 0.5 × 10 4  CFU/ml E. coli CFT073, prototype of UPEC, infecting 2.0 ± 0.5 × 10 5 cells/ml urinary bladder T24 epithelial cells. The highest protection (100%) is due to the bLf binding with host surface components even if an additional binding to bacterial surface components cannot be excluded. Of note, in the absence of bLf, UPEC survives and multiplies, while bLf significantly decreases bacterial intracellular survival. After these encouraging results, an observational survey on thirty-three patients affected by recurrent cystitis was performed. The treatment consisted in the oral administration of bLf alone or in combination with antibiotics and/or probiotics. After the observation period, a marked reduction of cystitis episodes was observed (p < 0.001) in all patients compared to the episodes occurred during the 6 months preceding the bLf-treatment. Twenty-nine patients did not report cystitis episodes (87.9%) whereas the remaining four (12.1%) experienced only one episode, indicating that bLf could be a worthwhile and safe treatment in counteracting recurrent cystitis., (© 2022.

Objective: To study the efficacy of liposomal bupivacaine on postoperative opioid requirement and pain following abdominal wall reconstruction., Summary Background Data: Despite the widespread use of liposomal bupivacaine in transversus abdominis plane block, there is inadequate evidence demonstrating its efficacy in open abdominal wall reconstruction. We hypothesized that liposomal bupivacaine plane block would result in decreased opioid requirements compared with placebo in the first 72 hours after surgery., Methods: This was a single-center double-blind, placebo-controlled prospective study conducted between July 2018 and November 2019. Adult patients (at least 18 yrs of age) undergoing open, elective, ventral hernia repairs with mesh placed in the retromuscular position were enrolled. Patients were randomized to surgeon-performed transversus abdominis plane block with liposomal bupivacaine, simple bupivacaine, or normal saline (placebo). The main outcome was opioid requirements in the first 72 hours after surgery. Secondary outcomes included total inpatient opioid use, pain scores determined using a 100 mm visual analog scale, length of hospital stay, and patientreported quality of life., Results: Of the 164 patients who were included in the analysis, 57 patients received liposomal bupivacaine, 55 patients received simple bupivacaine, and 52 received placebo. There were no differences in the total opioid used in the first 72 hours after surgery as measured by morphine milligram equivalents when liposomal bupivacaine was compared with simple bupivacaine and placebo (325 ± 225 vs 350 ± 284 vs 310 ± 272, respectively, P = 0.725). Similarly, there were no differences in total inpatient opioid use, pain scores, length of stay, and patient-reported quality of life., Conclusions: There are no apparent clinical benefits to using liposomal bupivacaine transversus abdominis plane block when compared with simple bupivacaine and placebo for open abdominal wall reconstruction., (Copyright © 2020 Wolters Kluwer Health, Inc.
