Background Caffeine is a routinely prescribed pharmacological active compound in neonatal intensive care units (NICU) for treating apnea of prematurity (AOP), which also decreases the risk of bronchopulmonary dysplasia and cerebral palsy in neonates. Caffeine-induced excessive calcium loss can promote the development of metabolic bone disease (MBD) in preterm neonates. This study aimed to evaluate the effect of the caffeine regimen on the development of osteopenia of prematurity (OOP), using serum alkaline phosphatase (serum-ALP) concentrations as a surrogate marker at the 4th week of life. Methods This retrospective cohort study was conducted including neonates of < 32 weeks gestational age (GA) and birth weight < 1500 g, admitted to NICU from April-2017 to December-2018 and received caffeine therapy till 28 days of life for AOP. Based on serum-ALP levels, formed the high and low-ALP groups. Neonatal characteristics, caffeine regimen, risk factors for OOP, including duration of parenteral nutrition (PN), exposure to medicines associated with MBD, and intake of essential vitamins and minerals, were compared in both groups. Predictors of OOP were analyzed through logistic regression. Results From the total of 268 participants, 52 (19%) developed OOP, mostly female (61.5%). In the high ALP group, the serum-ALP levels were significantly higher than in the low-ALP group (725.0 ± 143.8 vs 273.6 ± 55.0 units/L, p < 0.001). The high-ALP group received significantly (p < 0.001) higher daily and cumulative caffeine doses and were associated with a higher likelihood of developing OOP in this study cohort [cumulative dose (mg) (AOR = 1.082 95% CI 1.011 to 1.157) and daily dose (mg/kg/day) (AOR = 2.892 95% CI 1.392 to 6.007)]. Smaller GA was found directly related to OOP. Among the other medical risk factors, phosphorus intake was significantly low in the high-ALP group. No, significant relationship between duration of PN and use of steroids and diuretics, and intake of vitamins and minerals were identified. Conclusion The daily and cumulative doses of caffeine and smaller GA are associated with the development of OOP in this study cohort. Clinical randomized control studies are needed to validate the outcomes and determine the range of safest and most effective caffeine doses for treating AOP in preterm neonates.

Background: Community acquired pneumonia (CAP) is a common cause of childhood morbidity, attributed to every 1 in 500 hospitalization of children under the age of 5 years. While science made therapeutic advancements to battle CAP, the pathogens too have acquired resistance to many drugs. In this fight for dominance, Ampicillin plus Gentamicin and 3rd Gen Cephalosporins are nowadays the cornerstone of treatment. However, their efficacy varies in different parts of the world owing to differing levels of drug resistance. Objective: To compare the effect of Ampicillin and Gentamicin vs. third generation cephalosporin in treatment of severe community acquired pneumonia. Methodology: This Randomized Controlled Trial was conducted at the Dept. of Pediatrics (Ziauddin University Hospital) upon a sample of 74 patients (in two equal groups) of either gender, aged 2 months to 5 years, presenting with CAP. After taking written informed consent, data was recorded onto a pre-structured questionnaire containing inquiries pertaining to basic biodata, sociodemographic details, presenting complaints, immunization status of the pneumococcal and HIB vaccine, laboratory values, and treatment outcome. Results: The mean age of the sample stood at 15 months (SD ± 3) with a majority of the sample comprising of male children (52.7%). The mean weight stood at 8.7 kg (SD ± 0.9) and the mean height was recorded to be 74.2 cm (SD ± 11). The commonest symptoms included fever, fast breathing, chest in-drawing and added sounds. It was revealed that both treatments achieved successful treatment outcomes in all patients with no mortality. The resolution of symptoms however varied with faster resolution observed in the Cephalosporin group. Conclusion: After careful consideration, it can be concluded that 3rd generation cephalosporins is more efficacious at treatment of CAP with significantly faster resolution of disease symptoms.
