Treatment Summary

Neomycin is a type of antibiotic used to treat bacterial infections. It is made from the metabolic products of a certain type of bacteria. Neomycin is a complex made up of three different components, with neomycin B and C being the active ingredients. It is mainly used to treat bacterial infections in the ear, eye, and skin. Neomycin sulfate is the most common form of the drug and is available as a solution, otic suspension, and ophthalmic preparation. It is also available in over-the-counter topical products.

Effectiveness

How Neomycin Sulfate Affects Patients

Neomycin works by blocking the production of proteins in bacteria, which stops them from growing and surviving. This effect can last for up to 72 hours after taking the drug. Additionally, neomycin helps reduce the number of bacteria in the colon that produce ammonia, which can help improve neurological symptoms in those with hepatic coma. Neomycin works on both gram-positive and gram-negative bacteria, including the common species of E. coli and Klebsiella-Enterobacter group. However, some strains of E. coli, Klebsiella, and Proteus spp. have developed resistance to neomycin

How Neomycin Sulfate works in the body

Neomycin is an antibiotic that works by preventing bacteria from making proteins, which stops them from multiplying. It does this by binding to the bacterial ribosomes, which are responsible for making proteins, and blocking them from working correctly.

Neomycin Sulfate Toxicity & Overdose Risk

Neomycin sulfate has a low toxicity in mice, with an oral LD50 greater than 8 g/kg, a subcutaneous LD50 of 200 mg/kg in rats and 190 mg/kg in mice, and an intraperitoneal LD50 of 305 mg/kg in mice. It is unlikely to cause an overdose through oral ingestion, since it is poorly absorbed. However, it can still cause serious side effects such as nerve damage, hearing loss, and kidney damage when administered over time, especially in those with kidney impairment. Pregnant women should not take neomycin as it may cause total irreversible bilateral congen

Antibiotic Duration for Infections in Children

60 - 17

All Sexes

Birmingham, AL

Infections like pneumonia, skin and soft tissue infection (also called SSTI or cellulitis), and urinary tract infections (UTI) are some of the most common reasons children get admitted to the hospital. All three of these conditions require antibiotics for treatment. Although antibiotics are needed to treat the infection and help children feel better, taking them longer than needed can negatively impact children and their families. Negative impacts include things like the burdens of taking more medications and medication side effects. There are guidelines (instructions) from expert medical organizations that suggest the number of days children need antibiotics, but they give a wide range (between 5 and 14 days). Unfortunately, these guidelines are not based on high-quality studies. National data suggests that doctors often choose on the higher end of this range when writing prescriptions for children in the hospital. Our three caregiver co-investigators, other parents of hospitalized children, doctors, other care providers, and researchers, all believe that additional study is needed to determine the best length of antibiotic treatment that weighs both the benefits and harms of antibiotics. The goal of our study is to understand if 5 total days of antibiotic treatment compared to 10 total days of antibiotic treatment is better for children who have been in the hospital for pneumonia, SSTI, or UTI. We will study this question through a randomized control trial. In other words, half of the children will receive 5-days of antibiotics and the other half will receive 10-days of antibiotics. Children in this study (and their caregivers) will not know how many days of antibiotics they will receive to cure their infection because some children will take a placebo (or a pill without antibiotics in it). Only the pharmacy will know if a child is getting antibiotic or placebo (for days 6-10 of treatment). During the first phase of the trial (feasibility phase), 4 hospitals will enroll children in the study. We plan on enrolling 50 patients during this phase. We are starting with just 4 hospitals, so our study team can create and update our study plans if needed. We will closely review information about how many patients and families agree to participate, and if they have any trouble completing any part of the study. We will also interview families to understand the choice to participate in the study, the choice not to participate in the study, and what it is like to be in the study. During the second study phase, we will enroll 1150 more patients across all 11 hospitals. Families will complete short, daily surveys until the 15th day after they started antibiotics, then a larger survey at day 15, at day 20, and at day 30. These surveys will ask about the child's symptoms and recovery from their illness, how the antibiotics are making them feel, and if they had to go back to their doctor, emergency room, or hospital. The answers to these questions will be combined to measure how well the child did, balancing feeling better and having bad effects from the antibiotics. We will use mathematical tests to determine which antibiotic duration is better for treating these illnesses. We will complete other mathematical tests to see if all children should receive the same length of antibiotics or if certain children should be prescribed shorter courses and others longer courses.

Educational Tool for Urinary Tract Infections

18+

All Sexes

Houston, TX

Urine culture is the most common microbiological test in the outpatient setting in the United States. Unfortunately, contamination during collection is prevalent and undermines test accuracy, leading to incorrect diagnosis, unnecessary treatment, wasted laboratory resources, and inflated costs. Unnecessary antibiotic treatment increases the risk of developing antimicrobial resistance, one of the most serious threats to patients and public health. The goal of this clinical trial is to test whether a bilingual (English and Spanish) educational intervention, an animated video and pictorial flyer, can reduce urine culture contamination and associated inappropriate antibiotic use in adult patients visiting safety-net primary care clinics. The main questions it aims to answer are: 1. Does providing patients with a bilingual educational intervention reduce urine culture contamination rates? 2. Does the intervention lead to fewer unnecessary urinary antibiotic prescriptions? 3. Does providing patients with a bilingual educational intervention reduce contaminated urinalyses? Researchers will compare patients randomized to receive the educational intervention (video and flyer) to those receiving usual care to see if the intervention improves urine collection accuracy and reduces inappropriate antibiotic use. Participants will watch a short, animated video with step-by-step instructions for proper midstream clean-catch urine (MSCC) collection, receive a pictorial flyer (with stills from the video) reinforcing the instructions, and provide a urine sample for culture. Hypothesis: patients who receive the educational intervention will have: lower urine culture contamination rates (primary outcome), fewer urinary antibiotic prescriptions (secondary outcome), and fewer contaminated urinalyses (secondary outcome). The objectives are to (1) develop educational tools: Create an animated video and pictorial flyer with step-by-step urine collection instructions for women and men, developed through an iterative, stakeholder-engaged process, (2) assess acceptability: Use mixed methods (quantitative surveys and qualitative interviews) to evaluate and refine the tools for usability and cultural/linguistic appropriateness, and (3) test effectiveness: Conduct a randomized controlled trial to assess the intervention's impact on urine contamination rates, antibiotic prescribing, and patient satisfaction.
