Efficacy and Safety of Oral Probiotics on Ocular Symptoms and Gut Microbiome of Children with Vernal Keratoconjunctivitis

The primary goal of this study is to determine the effects of oral probiotics on the severity of ocular symptoms and the alterations of the gut microbiome of children (4-18 years old) with vernal keratoconjunctivitis. The current study will also assess the safety of oral probiotics among children with vernal keratoconjunctivitis. The main questions it aims to answer: 1- Does treatment with oral probiotics improve the severity of ocular symptoms in children with vernal keratoconjunctivitis? 2- Does treatment with oral probiotics alter the gut microbiome of children with vernal keratoconjunctivitis? Researchers will compare the ocular symptoms and gut microbiome between two groups receiving oral probiotics and placebo among children with vernal keratoconjunctivitis. Participants The participants will receive the oral probiotics and placebo ever day for one month. Record their regimen and keep a diary of their symptoms.

Impact of Probiotics on Gut Microbiome During Antibiotic Prophylaxis in Elective Orthopedic Surgery

This study aims to evaluate whether probiotics can help maintain a healthy gut microbiome in patients receiving prophylactic antibiotics during elective orthopedic surgery. Antibiotics, while effective in preventing infections, can disrupt the balance of gut bacteria, leading to dysbiosis. The study hypothesizes that the use of probiotics during the perioperative period can prevent or reduce this disruption, supporting gut health and overall well-being. The research seeks to answer whether combining probiotics with routine antibiotic prophylaxis can preserve gut microbiome balance and improve patient outcomes.
