The Effect of Peri-Operative Adjunctive Probiotics on Immunological Markers in Cases of Prosthetic Joint Infection of the Hip and Knee

Not Applicable

Not yet recruiting

• Conditions: Prosthetic-joint Infection

• Registration Number: NCT06919913
• Lead Sponsor: NYU Langone Health

Brief Summary

The purpose of this study is to determine whether probiotics in addition to standard of care (SOC) can improve immunological markers following treatment for prosthetic joint infection (PJI). The study aims to determine whether probiotics in addition to SOC decrease immunological markers following treatment for PJI, improve medical and surgical complications and mortality in patients with PJI, and lead to improved gastrointestinal (GI)-specific patient reported outcomes measures (PROMs) in patients with PJI.

Primary Outcome Measures

Name	Time	Method
Change in erythrocyte sedimentation rate (ESR)	Baseline, 6 weeks post-antibiotic therapy
Change in concentration of C-reactive protein (CRP)	Baseline, 6 weeks post-antibiotic therapy
Patient-Reported Outcomes Measurement Information System (PROMIS) - Global Health	Baseline, 6 weeks post-antibiotic therapy	The PROMIS Global Health measure consists of 10 items designed to assess an individual's overall health status, encompassing physical, mental, and social well-being. Each item is scored on a Likert scale of 1-5. Scores are reported on a T-score metric, with a mean of 50 and a standard deviation of 10, meaning a score of 50 represents the average for the reference population. Higher scores indicate better health.
Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR)	Baseline, 6 weeks post-antibiotic therapy	HOOS-JR contains 6 items from the original HOOS survey. Items are coded from 0 to 4, none to extreme, respectively. HOOS, JR is scored by summing the raw response (range 0-24) and then converting it to an interval score. The interval score ranges from 0-100, where 0 represents total hip disability and 100 represents perfect hip health.
Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR)	Baseline, 6 weeks post-antibiotic therapy	KOOS-JR contains 7 items from the original KOOS survey. Items are coded from 0 to 4, none to extreme respectively. KOOS, JR is scored by summing the raw response (range 0-28) and then converting it to an interval score. The interval score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.

Secondary Outcome Measures

Name	Time	Method
Number of participants with medical complications from prosthetic joint infection (PJI)	12 months post-surgery	Outcome measure will be assessed using review of electronic medical record.
Number of participants with surgical complications from PJI	12 months post-surgery	Outcome measure will be assessed using review of electronic medical record.
Mortality from PJI	12 months post-surgery
Digestion-associated Quality of Life Questionnaire (DQLQ)	12 months post-surgery	The DQLQ is a 9-items questionnaire assessing how digestive events and experiences affect mental well-being and physical ability. Participants respond based on how digestive events over the past seven days affected their quality of life using a 7-point frequency Likert scale (0 = never to 1 = always). Scores can range from 0 to 9; higher scores indicate a poorer digestion-associated quality of life.
The Short Health Scale for GI symptoms (SHS-GI)	12 months post-surgery	The SHS-GI is a 4-item questionnaire assessing the impact of gastrointestinal symptoms on quality of life, focusing on symptoms, social function, disease-related worry, and general well-being. Responses are graded on a 100-mm visual analog scale and maximum sum score for all items is 400, with higher values indicating worse outcome.
