Impact of early caffeine administration on respiratory outcomes in very preterm infants initially receiving invasive mechanical ventilation. BMJ Open Respir Res 2024; 11:e002285. [PMID: 39209350 PMCID: PMC11367330 DOI: 10.1136/bmjresp-2023-002285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 08/12/2024] [Indexed: 09/04/2024] Open
Abstract
OBJECTIVE The guidelines recommend early caffeine administration for preterm infants requiring non-invasive mechanical ventilation since earlier treatment is associated with better outcomes. The objective was to evaluate the impact of early caffeine therapy (within 24 hours after birth) on respiratory outcomes in very preterm infants who were initially receiving invasive mechanical ventilation. METHODS This was an observation cohort study from 1 January 2018 to 31 December 2022 based on a database that was prospectively collected and maintained. Infants who initially received invasive mechanical ventilation were divided into two groups based on the timing of caffeine initiation: within the first 24 hours after birth (early) and within 48 hours of birth or later (late). Generalised linear mixed models with a random effect model for the centre were used to assess the impact of different caffeine initiation times on neonatal outcomes. RESULTS Among the cohort of 9880 infants born at <32 weeks gestation, 2381 were eligible for this study (early initiation: 1758 (73.8%) and late initiation: 623 (26.2%)). For infants born at more than 28 weeks of gestation, the adjusted generalised linear mixed model showed that the duration of invasive mechanical ventilation was 1.34 (95% CI -2.40 to -0.27) days shorter and the incidence of moderate-to-severe bronchopulmonary dysplasia (BPD) was lower (adjusted OR 0.63; 95% CI 0.41 to 0.96) in the early caffeine group compared with the late caffeine group. CONCLUSION In very preterm infants who initially receive invasive mechanical ventilation, early administration of caffeine within 24 hours after birth can shorten the duration of invasive mechanical ventilation, reduce the incidence of moderate-to-severe BPD and improve respiratory outcomes. The very early initiation of caffeine treatment does not appear to be associated with any adverse outcomes. TRIAL REGISTRATION NUMBER ChiCTR1900025234.

Abstract
To assess the ideal time for caffeine administration in preterms, identifying its effects and safety. Study Design: Meta-analysis conducted including preterms <32 weeks GA or BW < 1500 g, comparing caffeine administration time: <24 x ≥24HOL, <48 x ≥48HOL, <72 x ≥72HOL. 18 studies included 76.998 patients. The median age of starting caffeine was the first 24 HOL. In the overall comparisons, there was reduction in patent ductus arteriosus (OR 0.71 [0.55, 0. 92]; low evidence), retinopathy of prematurity (OR 0.71 [0.54, 0.93]; moderate evidence), severe brain injury (OR 0.79 [0.70, 0.91]; moderate evidence), bronchopulmonary dysplasia (BPD) (OR 0.69 [0.59, 0.81]; moderate evidence), composite outcome of BPD or death (OR 0.76 [0.66, 0.88]; moderate evidence). Mortality increase was found (OR 1.20 [1.12, 1.29], very low evidence).Caffeine in the first 24 HOL has benefits in reducing morbidities associated with prematurity. Mortality finding is potentially due to survival bias.

Predictors for poor daily weight gain in preterm neonates exposed to different dose regimens of caffeine in ICU- a retrospective cohort study. BMC Pediatr 2024; 24:401. [PMID: 38898410 PMCID: PMC11188204 DOI: 10.1186/s12887-024-04850-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND With a wide therapeutic index, efficacy, ease of use, and other neuroprotective and respiratory benefits, caffeine citrate(CC) is currently the drug of choice for preterm neonates (PTNs). Caffeine-induced excessive energy expenditure, diuresis, natriuresis, and other CC-associated potential side-effects (CC-APSEs) result in lower daily-weight gain (WG) in premature neonates. This study aimed to evaluate the risk factors for daily-WG in neonates exposed to different dose regimens of caffeine in ICU. METHOD This retrospective cohort study included neonates of ≤ 36weeks gestational age (GA) and received CC-therapy. The same participants were followed for data analysis in two postnatal phases: 15-28 and 29-42 days of life (DOL). Based on daily CC-dose, formed group-I (received; standard-doses = 5 mg/kg/day), group-II (received;>5-7 mg/kg/day), and group-III (received;>7 mg/kg/day). Prenatal and postnatal clinical characteristics, CC-regimen, daily-WG, CC-APSEs, and concomitant risk-factors, including daily-caloric intake, Parenteral-Nutrition duration, steroids, diuretics, and ibuprofen exposure, were analyzed separately for group-II and group-III using group-I as standard. Regression analysis was performed to evaluate the risk factors for daily-WG. RESULTS Included 314 PTNs. During 15-28 DOL, the mean-daily-WG(MD-WG) was significantly higher in group-I than group-II [19.9 ± 0.70 g/kg/d vs. 17.7 ± 0.52 p = 0.036] and group-III [19.9 ± 0.70 g/kg/d vs. 16.8 ± 0.73 p < 0.001]. During 29-42 DOL the MD-WG of group-I was only significantly higher than group-III [21.7 ± 0.44 g/kg/d vs. 18.3 ± 0.41 g/kg/d p = 0.003] and comparable with group-II. During 15-28 DOL, observed CC-APSEs was significantly higher in group-II and III but during 29-42 DOL it was only significant in group-III. In the adjusted regression analysis for daily-WG during 15-28DOL, with respect to standard-dose, 5-7 mg/kg/day (β=-1.04; 95%CI:-1.62,-0.93) and > 7-10 mg/kg/day (β=-1.36; 95%CI:-1.56,-1.02) were associated with a lower daily-WG. However, during 29-42DOL, this association was present only for > 7-10 mg/kg/day (β=-1.54; 95%CI:-1.66,-1.42). The GA ≤ 27weeks (β=-1.03 95%CI:-1.24, -0.88) was associated with lower daily-WG only during 15-28DOL. During both periods of therapy, higher cumulative-caffeine dose and presence of culture proven sepsis, tachypnea, hyponatremia, and feeding intolerance were significantly associated with lower daily-WG. Conversely, daily kcal intake was found to be linked with an increase in daily-WG in both periods. CONCLUSION In this study cohort exposure to higher caffeine daily and cumulative doses is associated with lower postnatal daily-WG in PTNs than standard-daily doses, which may be due to its catabolic effects and CC-APSEs.

Abstract
Background Caffeine citrate (CC)-induced excessive energy expenditure, diuresis, natriuresis, and other CC-associated potential side effects (CC-APSEs) result in lower daily weight gain (WG) in premature neonates. This study aimed to assess higher CC-doses' effect on the mean daily-WG (MD-WG) and CC-APSE development, considering 5 mg/kg/day as the standard regimen. Method This retrospective cohort study included neonates of ≤36 weeks gestational age and received CC-therapy. The same participants were followed for data analysis in two postnatal phases: 15-28 and 29-42 days of life (DOL). Based on daily CC-dose, formed group-I=(5 mg/kg/day), group-II=(>5-7 mg/kg/day), and group-III=(>7 mg/kg/day). Data was analyzed separately for group-II and group-III using group-I as the standard. Results The study included 284 neonates. During phase-I, the MD-WG was significantly higher in group-I than group-II (19.9 ± .88 g/kg/d vs 17.5 ± .49, P = .031) and group-III (19.9 ± .88 g/kg/d vs 16.7 ± .71, P < .001). During 29-42 DOL, the MD-WG of group-I was only significantly higher than group-III (21.5 ± .42 g/kg/d vs 18.1 ± .39 g/kg/d, P = .003) and comparable with group-II. During 15-28 DOL, CC-APSEs were significantly higher in group-II and group-III but during 29-42 DOL was significant only in group-III. Conclusion Exposure to higher caffeine doses in this study cohort is associated with lower postnatal WG in preterm neonates than standard daily doses may be due to its catabolic effects and CC-APSEs.

Abstract
AIM To understand the variations in practice for caffeine use among neonatal units in the United Kingdom. METHODS An online survey was sent to every neonatal unit in the United Kingdom. RESULTS We received a response from 92 neonatal units (47%) with the proportion of response from special care, Local neonatal units, neonatal intensive care units and neonatal surgical units were 23%, 34%, 23% and 21% respectively. All the units reported the use of caffeine, and 40 units (46%) initiated caffeine within 24 h of birth. Fifty-nine units (64%) reported routine use of caffeine for pre-term infants <32 weeks. Seventy-one units (77%) reported that they continue caffeine for infants needing mechanical ventilation. Thirty-one units (34%) discontinued caffeine at 34 weeks post-menstrual age, irrespective of the respiratory support. Ten units (11%) reported discontinuation of caffeine only after weaning off all respiratory support, and 40% of units had a variable practice of discontinuing caffeine depending on the individual baby. Seventy-nine units (86%) reported they would regularly optimise caffeine dose based on weight checks. CONCLUSION Our survey showed some variation in practice with regards to the timing of caffeine initiation, gestational age cut-off for routine caffeine prescription and discontinuation.

Abstract
OBJECTIVE To quantify trends in caffeine use in infants born at <32 weeks' gestational age (GA), and to investigate the effects of early vs late caffeine on neonatal outcomes. STUDY DESIGN Retrospective propensity score matched cohort study using routinely recorded data from the National Neonatal Research Database of infants born at <32 weeks' GA admitted to neonatal units in England and Wales (2012-2020). RESULTS 89% (58 913/66 081) of infants received caffeine. In 70%, caffeine was started early (on the day of birth or the day after), increasing from 55% in 2012 to 83% in 2020. Caffeine was given for a median (IQR) of 28 (17-43) days starting on day 2 (1-3) and continued up to 34 (33-34) weeks postmenstrual age.In the propensity score matched cohort of 13 045 pairs of infants, the odds of preterm brain injury (early caffeine, 2306/13 045 (17.7%) vs late caffeine, 2528/13 045 (19.4%), OR=0.89 (95% CI 0.84 to 0.95)) and bronchopulmonary dysplasia (BPD) (early caffeine, 4020/13 045 (32.8%) vs late caffeine, 4694/13 045 (37.7%), OR=0.81 (95% CI 0.76 to 0.85)) were lower in the group that received early caffeine compared with those who received it later. CONCLUSIONS Early use of caffeine has increased in England and Wales. This is associated with reduced risks of BPD and preterm brain injury. Randomised trials are needed to find the optimal timing of caffeine use and the groups of infants who will benefit most from early administration of caffeine.

Abstract
OBJECTIVE To estimate if the odds of spontaneous intestinal perforation (SIP) are increased when antenatal steroids (ANS) given close to delivery are combined with indomethacin on day 1 after birth (Indo-D1). STUDY DESIGN A retrospective cohort study using the Neonatal Research Network (NRN) database of inborn infants, gestational age 220-286 weeks or birth weight of 401-1000 g, born between January 1, 2016 and December 31, 2019, and surviving >12 hours. The primary outcome was SIP through 14 days. Time of last ANS dose prior to delivery was analyzed as a continuous variable (using 169 hours for durations >168 hours or no steroid exposure). Associations between ANS, Indo-D1, and SIP were obtained from a multilevel hierarchical generalized linear mixed model after covariate adjustment. This yielded aOR and 95% CI. RESULTS Of 6851 infants, 243 had SIP (3.5%). ANS exposure occurred in 6393 infants (93.3%) and IndoD1 was given to 1863 infants (27.2%). The time (median, IQR) from last dose of ANS to delivery was 32.5 hours (6-81) vs 37.1 hours (7-110) for infants with or without SIP, respectively (P = .10). Indo-D1 was given to 51.9 vs 26.3% of infants with SIP vs no SIP, respectively (P < .0001). Adjusted analysis indicated no interaction between time of last ANS dose and Indo-D1 for SIP (P = .7). Indo-D1 but not ANS was associated with increased odds of SIP (aOR: 1.73, 1.21-2.48, P = .003). CONCLUSION The odds of SIP were increased after receipt of Indo-D1. Exposure to ANS prior to Indo-D1 was not associated with an increase in SIP.

[PMID: 37388282 PMCID: PMC10303785 DOI: 10.3389/fped.2023.1158286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 05/22/2023] [Indexed: 07/01/2023] Open
Abstract
Introduction Since December 2012, the prophylactic use of caffeine to treat AOP in preterm infants has been approved in China. This study aimed to investigate the relationship between early caffeine treatment initiation and the incidence of oxygen radical diseases in neonatology (ORDIN) in Chinese preterm infants. Methods A retrospective study was conducted at two hospitals in South China, involving 452 preterm infants with gestational ages less than 37 weeks. The infants were divided into early (227 cases, initiating within 48 h after birth) and late (225 cases, initiating over 48 h after birth) caffeine treatment group. Logistic regression analysis and Receiver Operating Characteristic (ROC) curves were used to evaluate the association between early caffeine treatment and the incidence of ORDIN. Results The results showed that extremely preterm infants in early treatment group had a lower incidence of PIVH and ROP compared to those in the late treatment group (PIVH, 20.1% versus 47.8%, P = 0.02; ROP, 70.8% versus 89.9%, P = 0.025). Very preterm infants in the early treatment group had a lower incidence of BPD and PIVH compared to those in the late treatment group (BPD, 43.8% versus 63.1%, P = 0.002; PIVH, 9.0% versus 22.3%, P = 0.001). Moreover, VLBW infants who received early caffeine treatment exhibited a decreased incidence of BPD (55.9% versus 80.9%, P = 0.000), PIVH (11.8% versus 33.1%, P = 0.000), and ROP (69.9% versus 79.8%, P = 0.043) compared to those in the late treatment group. Infants in the early caffeine treatment showed a reduced likelihood of PIVH (adjusted odds ratio, 0.407; 95%CI, 0.188-0.846) but did not exhibit a significant association with other terms of ORDIN. ROC analysis revealed that early initiation of caffeine treatment was associated with lower risk of BPD, PIVH, and ROP in preterm infants. Discussion In conclusion, this study demonstrates that early initiation of caffeine treatment is associated with a decreased incidence of PIVH in Chinese preterm infants. Further prospective investigations are necessary to verify and elucidate the precise effects of early caffeine treatment on complications in preterm Chinese infants.

Protective Effects of Early Caffeine Administration in Hyperoxia-Induced Neurotoxicity in the Juvenile Rat. Antioxidants (Basel) 2023; 12:antiox12020295. [PMID: 36829854 PMCID: PMC9952771 DOI: 10.3390/antiox12020295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/12/2023] [Accepted: 01/24/2023] [Indexed: 01/31/2023] Open
Abstract
High-risk preterm infants are affected by a higher incidence of cognitive developmental deficits due to the unavoidable risk factor of oxygen toxicity. Caffeine is known to have a protective effect in preventing bronchopulmonary dysplasia associated with improved neurologic outcomes, although very early initiation of therapy is controversial. In this study, we used newborn rats in an oxygen injury model to test the hypothesis that near-birth caffeine administration modulates neuronal maturation and differentiation in the hippocampus of the developing brain. For this purpose, newborn Wistar rats were exposed to 21% or 80% oxygen on the day of birth for 3 or 5 days and treated with vehicle or caffeine (10 mg/kg/48 h). Postnatal exposure to 80% oxygen resulted in a drastic reduction of associated neuronal mediators for radial glia, mitotic/postmitotic neurons, and impaired cell-cycle regulation, predominantly persistent even after recovery to room air until postnatal day 15. Systemic caffeine administration significantly counteracted the effects of oxygen insult on neuronal maturation in the hippocampus. Interestingly, under normoxia, caffeine inhibited the transcription of neuronal mediators of maturing and mature neurons. The early administration of caffeine modulated hyperoxia-induced decreased neurogenesis in the hippocampus and showed neuroprotective properties in the neonatal rat oxygen toxicity model.

Comparative efficacy and safety of caffeine citrate and aminophylline in treating apnea of prematurity: A systematic review and meta-analysis. PLoS One 2022; 17:e0274882. [PMID: 36121807 PMCID: PMC9484669 DOI: 10.1371/journal.pone.0274882] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Accepted: 09/06/2022] [Indexed: 11/18/2022] Open
Abstract
Background
Methylxanthine, including caffeine citrate and aminophylline, is the most common pharmacologic treatment for apnea of prematurity. However, due to the lack of high-quality evidence, there are no clear recommendations or guidelines on how to choose between caffeine and aminophylline.
Objective
This meta-analysis aimed to assess the comparative efficacy and safety of caffeine and aminophylline for apnea of prematurity, and provide reliable evidence for clinical medication in the treatment for apnea of prematurity.
Methods
PubMed, Scopus, Embase, EBSCO, Web of Science, and Cochrane databases were systematically searched from May 1975 to June 2022.
Results
Ten studies including a total of 923 preterm infants were evaluated. Our results showed that there was no significant difference in the effective rate of 1-3days between caffeine and aminophylline (OR 1.05, 95%CI: 0.40–2.74, P = 0.914). However, for side effects such as tachycardia (OR 0.22, 95%CI: 0.13–0.37, P<0.001) and feeding intolerance (OR 0.40, 95%CI: 0.23–0.70, P = 0.001), the incidence rate was lower in the caffeine group compared with the aminophylline group. No significant difference was found in hyperglycemia (OR 0.45, 95%CI: 0.19–1.05, P = 0.064).
Conclusion
This meta-analysis reveals that caffeine citrate and aminophylline have similar therapeutic effectiveness on respiratory function, but caffeine has fewer side effects and should be considered first for treatment.

Caffeine Restores Neuronal Damage and Inflammatory Response in a Model of Intraventricular Hemorrhage of the Preterm Newborn. Front Cell Dev Biol 2022; 10:908045. [PMID: 36035990 PMCID: PMC9411947 DOI: 10.3389/fcell.2022.908045] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
Germinal matrix-intraventricular hemorrhage (GM-IVH) is the most frequent intracranial hemorrhage in the preterm infant (PT). Long-term GM-IVH-associated sequelae include cerebral palsy, sensory and motor impairment, learning disabilities, or neuropsychiatric disorders. The societal and health burden associated with GM-IVH is worsened by the fact that there is no successful treatment to limit or reduce brain damage and neurodevelopment disabilities. Caffeine (Caf) is a methylxanthine that binds to adenosine receptors, regularly used to treat the apnea of prematurity. While previous studies support the beneficial effects at the brain level of Caf in PT, there are no studies that specifically focus on the role of Caf in GM-IVH. Therefore, to further understand the role of Caf in GM-IVH, we have analyzed two doses of Caf (10 and 20 mg/kg) in a murine model of the disease. We have analyzed the short (P14) and long (P70) effects of the treatment on brain atrophy and neuron wellbeing, including density, curvature, and phospho-tau/total tau ratio. We have analyzed proliferation and neurogenesis, as well as microglia and hemorrhage burdens. We have also assessed the long-term effects of Caf treatment at cognitive level. To induce GM-IVH, we have administered intraventricular collagenase to P7 CD1 mice and have analyzed these animals in the short (P14) and long (P70) term. Caf showed a general neuroprotective effect in our model of GM-IVH of the PT. In our study, Caf administration diminishes brain atrophy and ventricle enlargement. Likewise, Caf limits neuronal damage, including neurite curvature and tau phosphorylation. It also contributes to maintaining neurogenesis in the subventricular zone, a neurogenic niche that is severely affected after GM-IVH. Furthermore, Caf ameliorates small vessel bleeding and inflammation in both the cortex and the subventricular zone. Observed mitigation of brain pathological features commonly associated with GM-IVH also results in a significant improvement of learning and memory abilities in the long term. Altogether, our data support the promising effects of Caf to reduce central nervous system complications associated with GM-IVH.

Is Early Preventive Caffeine Safe and Effective in Premature Neonates? A Clinical Trial. Int J Pediatr 2022; 2022:8701598. [PMID: 35692738 PMCID: PMC9184212 DOI: 10.1155/2022/8701598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 03/16/2022] [Accepted: 05/17/2022] [Indexed: 11/30/2022] Open
Abstract
Background Advantages of caffeine for the treatment of apnea of prematurity (AOP) have prompted clinicians to use it as a preventive drug even before the occurrence of apnea. Objective To compare the effect of early preventive caffeine therapy with routine late preventive caffeine on the occurrence rate of apnea of prematurity, bronchopulmonary dysplasia (BPD) and related radiographic changes, necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), and patent ductus arteriosus (PDA), the need for mechanical ventilation, the length of mechanical ventilation, and the length of hospitalization. Materials and Methods In this open randomized clinical trial study, 90 preterm neonates with the gestational age of 25-35 weeks were divided into 2 groups: group A received caffeine during the first two days of life (early preventive caffeine), while group B received caffeine during the third to the tenth day of life (late preventive caffeine). The occurrence rate of AOP and other outcomes were the primary outcomes. The adverse effects of caffeine in each group were the secondary outcomes. Results The total occurrence rate of AOP was significantly higher (32.6%) in the late group versus (6.8%) in the early group (p = 0.002). The total occurrence rate of BPD was also significantly higher (37%) in the late group versus (18.2%) in the early group (p = 0.047). On the other hand, we found a lower need for mechanical ventilation, shorter length of mechanical ventilation, shorter length of hospitalization, and a lower occurrence rate of PDA, NEC, and IVH in the early group that was not significant. No adverse effect of caffeine was observed in each group. Conclusions Early preventive caffeine administration was associated with a significantly lower occurrence rate of AOP, BPD, and BPD radiologic changes. As other outcomes occurred lesser in the early group that were not significant, future studies with more participants are recommended. This study has been registered at the Iranian Registry of Clinical Trials (IRCT20160827029535N8).

Abstract
Bronchopulmonary dysplasia (BPD) is a chronic respiratory disease that occurs during the neonatal period and is commonly associated with prematurity. This condition results in a severe economic burden on society and the families involved. Caffeine is used not only for the treatment of apnea in prematurity, but also for the prevention of BPD. There are multiple clinical benefits of caffeine treatment, including improved extubation success, a reduced duration of mechanical ventilation, improved lung function, and a reduction of patent ductus arteriosus requiring treatment. These clinical benefits of caffeine for the treatment of BPD are supported by both clinical trials and evidence from animal models. However, the mechanism by which caffeine protects against BPD remains unclear. Here, we review the clinical value of caffeine in the prevention of BPD and its potential mechanisms of action, including anti-inflammatory, antioxidant, antifibrotic, and antiapoptotic properties, the regulation of angiogenesis, and diuretic effects. Our aim is to provide a new theoretical basis for the clinical treatment of BPD.

Abstract
Premature babies often suffer apnea of prematurity as a physiological consequence of an immature respiratory system. Hypercapnia may develop, and neonates with apnea of prematurity are at an increased risk of morbidity and mortality. The long-term effects of apnea of prematurity or their treatments are less clear. While a number of treatment options exist for apnea of prematurity, there is no clear-cut "first-line" approach or gold standard of care. Effective treatments, such as caffeine citrate, carbon dioxide inhalation, nasal continuous positive airway pressure, nasal intermittent positive pressure ventilation, and others, may be associated with safety concerns. More conservative treatments are available, such as kangaroo care, postural changes, and sensory stimulation, but they may not be effective. While apnea of prematurity resolves spontaneously as the respiratory system matures, it can complicate neonatal care and may have both short-term and long-term consequences. The role, if any, that apnea of prematurity may play in mortality of preterm neonates is not clear.

Abstract
BACKGROUND Therapeutic initiation of methyxanthines for treatment of apnea in preterm infants was the standard policy. Caffeine therapy is beneficial for various outcomes of preterm infants. AIM To evaluate the efficacy of early prophylactic compared to routine therapeutic caffeine therapy on duration of oxygen support and other outcomes of preterm infants. METHODS In a randomized controlled trial including preterm infants < 32 weeks' gestation, prophylactic (in the first 72 h of life) versus therapeutic (only if apnea exists or infant requires mechanical ventilation) decision of caffeine was compared. The primary outcome was the duration of oxygen therapy. Secondary outcomes included duration of respiratory support modalities; bronchoplumonary dysplasia (BPD); necrotizing enterocolitis; intra-ventricular hemorrhage; retinopathy of prematurity; length of hospital stay (LOS); neonatal mortality; and caffeine side effects. RESULTS We enrolled 90 infants in the prophylactic and 91 infants in therapeutic groups respectively. Prophylactic caffeine decreased the duration of oxygen therapy [median and IQR of 28 (18-36) days versus 34 (23-51) days, p = .005 respectively]. Prophylactic caffeine significantly decreased the durations of respiratory support modalities, LOS, and incidences of mild to moderate BPD without reported effects on the incidence of severe BPD or other clinical outcomes compared to therapeutic caffeine. A significantly higher proportion of infants in the prophylactic caffeine group did not require mechanical ventilation during their NICU admission and a significant lower proportion required late mechanical ventilation compared to the prophylactic caffeine group. CONCLUSION Prophylactic caffeine decreased the duration of oxygen therapy, invasive and noninvasive ventilation, incidences of mild to moderate BPD, and LOS in preterm infants.

Abstract
Caffeine as tested in the CAP trial is safe and effective for preterm infants with birthweights less than 1250 g. Evidence for its use beyond the indications and timing used in this trial is of low quality and conflicting. Some studies suggest that earlier use of caffeine increases the risk of mortality while others suggest it has important benefits. It appears that infants with apnea of prematurity and those receiving assisted ventilation are the most likely to benefit from caffeine. Based on currently available evidence, routine early prescription of caffeine does not appear to be indicated. Infants continue to have potentially damaging episodes of hypoxia secondary to apnea beyond 34 weeks' postmenstrual age. It is unclear whether prolonged use of caffeine improves outcomes in these infants. Randomized trials to resolve these uncertainties are required. They need to be large, at least the size of the CAP trial, and include neurodevelopmental outcomes.

Abstract
BACKGROUND Caffeine is indicated for the management of apnoea of prematurity and extubation in preterm infants. Early initiation of caffeine administration has increased in the past decades with the purpose of reducing respiratory morbidity. However, there might be harms associated with this approach. This systematic review aims to assess whether early administration of caffeine reduces morbidity and mortality in preterm infants. METHODS The methods were published in a preregistered protocol. The literature search was performed in February 2019 with no restrictions for language or publication date. Randomised controlled trials (RCTs) and cohort studies comparing early versus late caffeine administration to infants born before week 34 were included. RESULTS Two RCTs and 14 cohort studies were included. All studies but one had a serious/critical overall risk of bias. Few studies reported on long-term or patient-relevant outcomes. No meta-analysis could be performed. CONCLUSION Based on the available evidence, no conclusions about the optimal timing of caffeine administration can be drawn. There are inherent methodological problems in the cohort studies. RCTs are needed to answer the question of optimal timing for caffeine administration in neonatal care. Future trials should focus on outcomes relevant to patients and their families and include long-term outcomes.

Abstract
Objective There are differences in the adoption rates of less invasive surfactant administration (LISA) worldwide. We aimed to describe and analyze the process of LISA introduction at the country level. Methods A standardized training program (33 courses covering >500 neonatologists) was followed by a cohort study. Data regarding consecutive LISA procedures were acquired over 12 months in 31 tertiary neonatal centers, using a dedicated on-line platform. Results Of 500 LISA procedures, 75% were performed by specialists and 25% by residents. The mean percentage share of LISA in all surfactant therapies was 24%, which represents a 6-fold increase compared to previous years. After 12 months, 76% of the procedures were rated “easy/very easy” vs 59% at baseline (p<0.05). Surfactant re-treatment rate was 15%. Twenty-three percent of infants required mechanical ventilation within 72 hours of life. Oxygen desaturation and surfactant reflux were the most frequent complications. Unlike previous reports describing exclusive use of nasal continuous positive airway pressure (nCPAP) during LISA, majority of procedures (63%) were carried out using nasal intermittent positive pressure ventilation (NIPPV) or Bilevel Positive Airway Pressure (BiPAP). Efficacy of LISA with NIPPV or BiPAP was not significantly different from that with nCPAP (22.4% vs 24.5% of cases requiring intubation). Ventilation was provided with nasal cannulas or nasal masks (90%) and rarely with “RAM” cannulas or nasopharyngeal tubes. Rigid catheters were preferred (88.4%); tracheal insertion was successful at first attempt in 87% of cases. Majority of infants (79%) received no premedication prior to the procedure and almost all were given caffeine citrate. Median time of instillation was 1.5 minutes. Conclusions The LISA procedure does not appear to be technically difficult to master. Training combining theory with practical exercises is an efficient implementation strategy. Variations in adoption rates indicate the need for additional, more personalized teachings in some centers.

Abstract
AIM To investigate interinstitutional differences in preterm infant stabilisation between two European tertiary neonatal centres with particular focus on intubation timing, surfactant administration, caffeine therapy and neonatal morbidity and mortality. METHODS Retrospective (2012-2014) study of very low birth weight (VLBW) preterm infants admitted to John Radcliffe Hospital (UK centre) and Charité Medical Centre (German centre). Timing of intubation, surfactant and caffeine administration and respiratory outcomes were examined. RESULTS Gestational age, birth weight and five-minute Apgar scores of VLBW infants from the UK centre (n = 86) were comparable to those from the German centre (n = 96). Significant differences in antenatal steroid therapy, intubation timing and surfactant therapy were noted. Timing of caffeine initiation differed significantly between centres (median 0 [0-2.5] UK vs. 2 [1.5-4] days German centre); however, caffeine was discontinued at a similar corrected gestational age of 34.7 weeks. Mechanical ventilation was significantly longer at the UK centre, but there was no difference in bronchopulmonary dysplasia (BPD) (44% UK vs. 36% German centre) or mortality (15% UK vs. 13% German centre). CONCLUSION Timing of primary intubation and caffeine therapy differed significantly between centres. However, earlier intubation and caffeine administration in the UK centre were not associated with a changed incidence of BPD.

Abstract
Aim: To evaluate the effect of the initial dose of poractant alfa on clinical outcomes in neonatal respiratory distress syndrome (RDS) and to assess adherence to treatment guidelines recommending a dose of 200 mg/kg. Methods: Records of neonates who received poractant alfa with a less invasive technique (LISA) or with the INtubate-SURfactant-Extubate (INSURE) technique were retrieved from the aggregated datasets of three prospective RDS studies conducted between 2015 and 2019. The impact of poractant dose on neonatal outcomes was analyzed by multivariate logistic regression. The primary endpoint was the need for early (<72 h of life) mechanical ventilation (MV). Typical complications of prematurity and the need for surfactant retreatment were secondary endpoints. Deviation from the 200 mg/kg dose of surfactant was a measure of compliance with the treatment guidelines. As a complementary analysis, the rates of adverse outcomes were compared for infants receiving high (200 mg/kg ±10%) and low (100 mg/kg ±10%) doses of poractant. Results: Of 994 eligible infants, 574 received poractant alfa with LISA, and 420 received poractant with INSURE. A logistic regression model using data from all 994 infants showed that the surfactant dose had a significant effect on reducing the need for MV and retreatment; the respective odds ratios were 0.92 (95% CI: 0.90-0.95) and 0.93 (95% CI: 0.90-0.96) per 10-mg/kg dose increment of poractant alfa. This dose effect was observed across all gestational age ranges and in infants treated with LISA. In newborns treated with INSURE, the dose of surfactant only influenced the rates of retreatment (p = 0.036) but not MV (p = 0.170). No impact on other neonatal outcomes was observed. In the subset of infants who received high (N = 502) and low (N = 58) doses of poractant, the high-dose group had lower rates of MV (34 vs. 48%, p = 0.042) and lower rates of retreatment (11 vs. 21%, p = 0.045). Surfactant underdosage increased with gestational age and ranged from a minimum of -3 mg/kg in <26 weeks to a maximum of -23.5 mg/kg in >32 weeks. Conclusions: The initial dose of poractant alfa significantly impacts the need for invasive ventilation and retreatment. More mature newborns are at a greater risk of underdosing.

Abstract
The incidence of preterm birth is increasing, leading to a growing population with potential long-term pulmonary complications. Apnoea of prematurity (AOP) is one of the major challenges when treating preterm infants; it can lead to respiratory failure and the need for mechanical ventilation. Ventilating preterm infants can be associated with severe negative pulmonary and extrapulmonary outcomes, such as bronchopulmonary dysplasia (BPD), severe neurological impairment and death. Therefore, international guidelines favour non-invasive respiratory support. Strategies to improve the success rate of non-invasive ventilation in preterm infants include pharmacological treatment of AOP. Among the different pharmacological options, caffeine citrate is the current drug of choice. Caffeine is effective in reducing AOP and mechanical ventilation and enhances extubation success; it decreases the risk of BPD; and is associated with improved cognitive outcome at 2 years of age, and pulmonary function up to 11 years of age. The commonly prescribed dose (20 mg·kg-1 loading dose, 5-10 mg·kg-1 per day maintenance dose) is considered safe and effective. However, to date there is no commonly agreed standardised protocol on the optimal dosing and timing of caffeine therapy. Furthermore, despite the wide pharmacological safety profile of caffeine, the role of therapeutic drug monitoring in caffeine-treated preterm infants is still debated. This state-of-the-art review summarises the current knowledge of caff-eine therapy in preterm infants and highlights some of the unresolved questions of AOP. We speculate that with increased understanding of caffeine and its metabolism, a more refined respiratory management of preterm infants is feasible, leading to an overall improvement in patient outcome.

Abstract
BACKGROUND This study assessed the clinical characteristics of neonatal acute respiratory distress syndrome (ARDS) and differences in therapy in comparison to RDS. MATERIAL AND METHODS The clinical data of 925 preterm infants with respiratory distress were collected and divided into 4 groups. Group A and B both met the diagnosis of neonatal RDS, whereas infants in group B also showed inflammatory response. Group C met the Montreux definition of neonatal ARDS and group D was the control. RESULTS We found that 73.50% of the 925 preterm infants were diagnosed with RDS, of which RDS with inflammatory response accounted for 42.05%. ARDS accounted for 5.29% and control group accounted for 21.19%. Group C infants were the heaviest (2168.16±654.43 g) and had the oldest gestational age. The pregnancy-induced hypertension was highest (30.07%) in group B and lowest in group D (13.26%). Group C had higher iNO and longer invasive ventilator times, but had less frequent surfactant treatment, as well as shorter oxygen time and hospital stay. Group B had significantly longer invasive ventilator use than in Group A. In group A, PDA, ROP, and PPHN were the most common complications, with morbidity rates at 78.35%, 8.4%, and 25.77%, respectively, while group C had higher incidence of PDA (71.42%) and coagulation disorders (38.77%). CONCLUSIONS ARDS mainly occurs in late preterm infants. Its treatment is dependent on iNO and invasive ventilator-assisted therapy, and the surfactant treatment rate was relatively lower in comparison to RDS. RDS accompanied with inflammatory response is also dependent on prolonged use of an invasive ventilator.

Abstract
Phosphodiesterases (PDEs) are a superfamily of enzymes that catalyze the hydrolysis of phosphodiester bonds of 3',5' cyclic adenosine and guanosine monophosphate (cAMP and cGMP). PDEs control hydrolysis of cyclic nucleotides in many cells and tissues. Inhibition of PDEs by selective or nonselective PDE inhibitors represents an effective targeted strategy for the treatment of various diseases including respiratory disorders. Recent data have demonstrated that PDE inhibitors can also be of benefit in respiratory distress in neonates. This article outlines the pharmacological properties of nonselective and selective PDE inhibitors and provides up-to-date information regarding their use in experimental models of neonatal respiratory distress as well as in clinical studies.

Abstract
Background and Aim: To analyze the influence on weight gain of infants exposed to two dosage regimens of oral caffeine citrate (CC) for apnea of prematurity. Methods: Retrospective descriptive observational study of an eligible very low birth weight cohort over a 15-year period in an Irish University hospital. Data were analyzed between two distinct postnatal ages: 14–28 and 29–56 days. Results: During the 15-year study, 457 infants were prescribed caffeine. Among the 14–28-day group, after applying exclusion criteria, 418 infants qualified. Two hundred forty-eight infants received 5 mg/(kg·day) and 170 received 10 mg/(kg·day) of CC. Among the 29–56-day group, 362 infants were identified and after applying exclusions, 332 fulfilled entry criteria [214 on 5 mg/(kg·day) and 118 on 10 mg/(kg·day) regimen]. Baseline characteristics of infants were comparable between groups without statistically significant differences. Mean daily weight gain (MDWG) in grams from day 14 to 28 showed a higher rate of increase for the 5 mg/(kg·day) group compared with the 10 mg/(kg·day) group (17.2 ± 12 g vs. 13.0 ± 10.2 g [p = 0.04]). From day 29 to 56, also MDWG was higher among infants on 5 mg/(kg·day) of CC compared with 10 mg/(kg·day) group (15.6 ± 10.8 g vs. 10.2 ± 9.8 g [p = 0.011]). Conclusion: While a variety of measures are optimized to promote postnatal weight gain of premature infants close to an ideal intrauterine growth curve, not paying sufficient attention to one of the most widely used catabolic agents in neonatology is questionable and warrants vigilance. Additional nutritional measures could be offered to those with prolonged caffeine exposure.
