Brief summary

This randomized controlled trial at Sahiwal Teaching Hospital (April 2024-March 2025) compared azithromycin and erythromycin for managing preterm premature rupture of membranes (PPROM) in 250 women (28-33+6 weeks gestation). Participants received either azithromycin 500 mg once daily or erythromycin 250 mg every six hours for seven days.

Detailed description

Background: Preterm premature rupture of membranes (PPROM) is a significant contributor to preterm births and neonatal morbidity worldwide. While erythromycin has traditionally been used for this purpose, limitations related to tolerability and dosing frequency have prompted the evaluation of alternative agents such as azithromycin. Objective: To compare the clinical efficacy of azithromycin versus erythromycin in the management of PPROM, focusing on latency period, maternal infection rates, neonatal outcomes, and overall drug tolerability. Methodology: This randomized controlled trial was conducted at Sahiwal Teaching Hospital from 01-04-2024 to 31-03-2025. A total of 250 pregnant women with confirmed PPROM between 28+0 and 33+6 weeks of gestation were randomly allocated into two groups: Group A oral dose of azithromycin 500mg once daily for seven days, while Group B received erythromycin 250 mg orally every six hours for seven days. Primary outcomes included latency period, incidence of chorioamnionitis, mode of delivery, and key neonatal indicators such as APGAR scores, NICU admission rates, respiratory distress syndrome (RDS), and neonatal mortality.

Primary

MeasureTime frameDescription
Maternal Outcome07 DaysPrimary Outcome Measure 1 Name: Incidence of Clinical Chorioamnionitis Description: Clinical chorioamnionitis will be diagnosed based on predefined clinical criteria including maternal fever (≥38°C), maternal tachycardia, uterine tenderness, and foul-smelling amniotic fluid, supported by laboratory evidence of infection. Measurement Tool: Daily standardized clinical assessment and laboratory evaluation. Time Frame: Within 7 days of enrollment or until delivery, whichever occurs earlier. Unit of Measure: Number of participants diagnosed with clinical chorioamnionitis. Primary Outcome Measure 2 Name: Maternal Laboratory Evidence of Infection Description: Maternal inflammatory response will be assessed using total leukocyte count (TLC) and C-reactive protein (CRP) levels to support the diagnosis of infection. Measurement Tool: Venous blood sampling for TLC and CRP. Time Frame: Measured on alternate days until delivery
Neonatal Outcomes07 daysPrimary Outcome Measure 3 Name: Neonatal Birth Weight Description: Neonatal birth weight measured immediately after delivery. Measurement Tool: Calibrated digital weighing scale. Time Frame: At birth. Unit of Measure: Grams. Primary Outcome Measure 4 Name: APGAR Score at 1 Minute Description: Assessment of neonatal APGAR score at 1 minute after birth. Measurement Tool: Standard APGAR scoring system. Time Frame: 1 minute after birth. Unit of Measure: Score (0-10).
