RESUMEN
AIMS: To assess the extent of off-label drug use and the occurrence of suspected adverse drug reactions (ADRs) among paediatric patients in Italian hospitals. METHODS: We conducted a 2-year prospective cohort study across 22 Italian hospital wards from September 2020 to September 2022. As part of the surveillance project, we performed a 6-month retrieval of all reported ADRs and evaluated all drug prescriptions for their possible off-label use. Following an educational project on pharmacovigilance addressed to healthcare professionals in participating wards, the same data collection was performed. RESULTS: Among the 892 patients included in the study, 64% were admitted to paediatric wards and 36% to neonatal wards. Fifty per cent of all drugs prescribed were used off-label and mainly concerned the administration of a different dose from the one authorized. In neonatal wards, off-label prescriptions occurred slightly more often, with antibacterials being the most frequently used off-label drugs. A total of 35 reports of suspected ADRs were collected, five before the educational project and 30 afterwards. Based on product licence, 10 of the total 35 reports concerned at least one off-label drug use. CONCLUSIONS: The off-label use of drugs in treating paediatric patients was extensive in Italian hospitals. Regulatory interventions are needed to promote the use of drugs based on the latest available literature and improve ADR reporting on children. Paediatric indications and dosages of the drugs most commonly used in children should be supported by appropriate ad hoc studies.

OBJECTIVE: The standard treatment for epilepsy is based on the appropriate use of antiseizure medications (ASMs) to prevent the recurrence of seizures. For the newer ASMs, however, little information on their safety profile is available. This work sought to fill this gap by creating a database for ASM use in a paediatric hospital and the adverse drug reactions (ADRs) reported. METHODS: This observational single-centre study was conducted from January 2018 to December 2020 and recorded the type of ASM treatment for paediatric epileptic patients cared for at the Neuropsychiatry Unit of the Salesi Paediatric Hospital in Ancona, Italy, as well as any ADRs. RESULTS: In all, 519 patients were admitted to the ward with a diagnosis of epilepsy, 362 (69.7%) of whom were prescribed ASMs. Valproic acid was the most frequently prescribed drug (29.96%), followed by levetiracetam (13.97%) and carbamazepine (9.16%). We recorded 24 ADRs in 20 patients, half of which (n=12) occurred with polytherapy. Among the ADRs associated with monotherapy, 25% (n=6) were induced by carbamazepine; 12.5% (n=3) were associated with either valproic acid, clonazepam or lamotrigine; 8.3% (n=2) were associated with perampanel, clobazam or levetiracetam; while one patient experienced ADR due to vigabatrin, one due to ethosuximide and one due to cannabidiol. The median patient age was 7.5 years and most ADRs were not serious. CONCLUSION: During the 3-year observation period, 6% of epileptic patients on ASMs showed one or more ADRs. Carbamazepine was responsible for about a quarter of these reactions, two of which were serious. Half of the ADRs occurred with polytherapy, which often included valproic acid and stiripentol. It is to be hoped that such active pharmacovigilance through the collaboration of hospital pharmacists and physicians will serve to improve the management of treatment.
RESUMEN
BACKGROUND & AIMS: Preterm infants are at increased risk of long-term neurodevelopmental disabilities (NDD). Long chain n-3 fatty acids play a key role during the development of the central nervous system and some studies in preterm infants showed benefits of docosahexaenoic acid and arachidonic acid supplementation for visual and cognitive development. In recent years fish oil has been added to the fat blend of intravenous (IV) lipid emulsions (LE) but to date scanty data are available on neurodevelopmental outcome of preterm infants that received fish oil containing LE. We studied the effect of fish oil containing IV LE vs standard IV LE on neurodevelopment in a large cohort of preterm infants who received routine parenteral nutrition (PN) from birth. METHODS: We retrospectively reviewed the neurodevelopmental outcome of 477 preterm infants (birth weight (BW): 400-1249 g and gestational age (GA) at birth: 24+0 - 35+6 weeks (W)) admitted to our NICU between Oct-2008 and June-2017, who received routine PN with different LE, with and without fish oil (IV-FO vs CNTR). We compared neurodevelopment at 2 years corrected age by the Bayley III development scale and the incidence of NDD. RESULTS: Demographics, birth data and the incidence of the main clinical short-term outcomes of prematurity were similar in the two groups (IV-FO: n = 178, GA 197 ± 14 days, BW 931 ± 182 g; CNTR: n = 192, GA 198 ± 15 days, BW 944 ± 194 g). No differences were found in maternal demographics nor in parental education between the two groups. Cognitive score was not significantly different between IV-FO and CNTR (92 ± 15 vs 93 ± 13, p = 0.5). No differences were found in motor and language scores, and in the incidence of NDD in the two groups. CONCLUSIONS: Contrary to our hypothesis, the use of fish oil containing LE in a large cohort of preterm infants on routine PN did not result in better neurodevelopment. Large randomized controlled trials powered for neurodevelopment are needed to clarify the impact of the widely used fish oil containing LE on neurodevelopment of preterm infants.

OBJECTIVES: To study the association of hypertriglyceridemia and of lipid tolerance with clinical and nutritional data in preterm infants receiving routine parenteral nutrition. DESIGN: We retrospectively studied 672 preterm infants (gestational age <32 weeks) with birth weight <1250 g, consecutively admitted to our NICU, born between 2004 and 2018. Selected prenatal data and interventions, parenteral intakes and diseases were considered. Hypertriglyceridemia was defined as plasma triglycerides >250 mgâ dL-1. Lipid tolerance was defined as the ratio of plasma triglycerides to the intravenous lipid intake at the time of sampling. Variables associated to hypertriglyceridemia and to lipid tolerance were identified by multiple logistic and linear regression analyses. RESULTS: Hypertriglyceridemia occurred in 200 preterm infants (30%), ranging from 67% at 23 weeks to 16% at 31 weeks' gestation. In 138 infants (69%) hypertriglyceridemia occurred at a lipid intake of 2.5 gâ kg-1 or less. Lipid tolerance was reduced especially in infants of less than 28 weeks' gestation (14.3 ± 9.3 vs 18.8 ± 10.2, respectively, p < 0.001). Lipid tolerance was negatively associated with respiratory distress syndrome (OR = -1.14, p = 0.011), patent ductus arteriosus (OR = -1.73, p < 0.001), small for gestational age (OR = -2.96, p < 0.001), intraventricular haemorrhage (OR = -3.96, p < 0.001), late onset sepsis (OR = -8.56, p = 0.039). CONCLUSION: Preterm infants on routine parenteral nutrition were able to tolerate markedly lower intravenous lipid intakes than the recommended target values of current guidelines. Lipid tolerance was associated with some of the major complication of prematurity, possibly at risk of developing hypertriglyceridemia.

INTRODUCTION: The benefits of intravenous (IV) fish oil (FO), as a source of n-3 long-chain polyunsaturated fatty acids, on lung growth in preterm infants, remain controversial. AIM: To evaluate if IV FO improves lung growth in small preterm infants on routine parenteral nutrition (PN). MATERIALS AND METHODS: We retrospectively reviewed prospectively collected data of preterm infants with a birth weight <1250 g who received routine PN from birth. We compared patients who received FO containing IV lipid emulsions with infants who received conventional emulsions (CNTR). The oxygen saturation (SpO2 ) to a fraction of inspired oxygen (FiO2 ) ratio (SFR) at 36 weeks (W) of gestation was chosen as the primary outcome variable to assess lung growth. RESULTS: Four hundred and seventy-seven infants were studied: 240 received IV FO and 237 CNTR. While exposure to antenatal glucocorticoids was higher in IV FO group than in CNTR (95 vs 90%, P = .04), there were no differences in birth data, enteral and parenteral nutrition intakes, ventilator supports and drug therapies. The incidence of the most common complications of prematurity at 36 W was not different (bronchopulmonary dysplasia was 27 vs 21% in IV FO vs CNTR infants, P = .1). Weight gain from birth to 36 W was marginally, but significantly, higher (+0.5 g/kg/d, P = .03) in IV FO group vs CNTR. SFR increased from 32 W to 36 W in all study patients (P < .001). IV FO infants had significantly lower SpO2 from 33 W to 35 W (P < .001) and lower (worse) SFR at 36 W (432 ± 57 vs 444 ± 51, P = .026) compared to CNTR. CONCLUSION: Contrary to our hypothesis, the use of FO containing IV lipid emulsions for the routine PN of the preterm infant did not improve lung growth compared to the infants who received conventional IV lipid emulsions.

BACKGROUND & AIMS: Long chain n-3 fatty acids (n-3 LCPUFA) play a pivotal role during central nervous system development and the provision of docosahexaenoic acid (DHA) is recommended for the preterm infant. However, there are concerns that oral fish oil, which is a good source of DHA, may adversely affect growth of preterm infants, as it decreases arachidonic acid (ARA). It has been about ten years since fish oil was added to the fat blend of intravenous (IV) lipid emulsions (LE) but information on growth and other clinical outcomes of preterm infants is still scarce. We studied the effect of fish oil containing IV LE vs standard IV LE on growth in a large cohort of preterm infants who received routine parenteral nutrition (PN). METHODS: We retrospectively reviewed growth data of 546 preterm infants with a birth weight (BW) < 1250 g consecutively admitted to our NICU between Oct-2008 and Jun-2017 who received PN starting from the first day of life. Individual patients received only one of 5 commercially available IV LE. For the purpose of this study we grouped the patients who received the fish oil containing LE (IV-FO) and those who received conventional LE (CNTR). We compared PN and enteral nutrition (EN) intakes, and growth from birth to 36+0 weeks post-menstrual age (W PMA). RESULTS: Demographics, birth data and the incidence of the main complications of prematurity were similar between the two groups (IV-FO: n = 240, Gestational age (GA) 197 ± 16 d, BW 942 ± 181 g; CNTR: n = 237, GA 199 ± 17 d, BW 960 ± 197 g). No difference was found in PN and EN energy and macronutrient intakes from birth to 36+0W PMA, as well as in the proportion of human milk to infant milk formula. Weight gain from the regained BW to 36+0W PMA was slightly but significantly higher in IV-FO group: 17.3 ± 2.8 and 16.8 ± 2.7 gâkg-1âd-1, IV-FO and CNTR respectively (p = 0.03). There was no difference in length gain and head growth nor in body size at 36+0W PMA between the two groups. CONCLUSIONS: The use of IV fish oil did not negatively affect weight gain in a cohort of preterm infants. Large randomized controlled trials are needed to assess the effect of IV fish oil on the complication of prematurity and on selected domains of infant development.

Several studies reported the association between total plasma phytosterol concentrations and the parenteral nutrition-associated cholestasis (PNAC). To date, no data are available on phytosterol esterification in animals and in humans during parenteral nutrition (PN). We measured free and esterified sterols (cholesterol, campesterol, stigmasterol, and sitosterol) plasma concentrations during PN in 16 preterm infants (500-1249 g of birth weight; Preterm-PN), in 11 term infants (Term-PN) and in 12 adults (Adult-PN). Gas chromatography-mass spectrometry was used for measurements. Plasma concentrations of free cholesterol (Free-CHO), free phytosterols (Free-PHY) and esterified phytosterols (Ester-PHY) were not different among the three PN groups. Esterified cholesterol (Ester-CHO) was statistically lower in Preterm-PN than Adult-PN. Preterm-PN had significantly higher Free-CHO/Ester-CHO and Free-PHY/Ester-PHY ratios than Adult-PN (Free-CHO/Ester-CHO: 1.1 ± 0.7 vs. 0.6 ± 0.2; Free-PHY/Ester-PHY: 4.1 ± 2.6 vs. 1.3 ± 0.8; *P < 0.05). Free-CHO/Ester-CHO and Free-PHY/Ester-PHY ratios of Term-PN (Free-CHO/Ester-CHO: 1.1 ± 0.4; Free-PHY/Ester-PHY: 2.9 ± 1.7) were not different from either Preterm-PN or from Adult-PN. Plasma Free-CHO/Ester-CHO and Free-PHY/Ester-PHY were unchanged after 24 h on fat-free PN both in Preterm-PN and in Adult-PN. Free-PHY/Ester-PHY did not correlate with phytosterol intake in Preterm-PN. Free-PHY/Ester-PHY of Preterm-PN was positively correlated with the Free-CHO/Ester-CHO and negatively correlated with gestational age and birth weight. In conclusion, PHY were esterified to a lesser extent than CHO in all study groups; the esterification was markedly decreased in Preterm-PN compared to Adult-PN. The clinical consequences of these findings warrant further investigations.

BACKGROUND & AIMS: Provision of long chain polyunsaturated fatty acids (LCP) both of the omega-3 and omega-6 families is recommended for preterm infants (PI). Fish oil (FO) contains omega-3 and omega-6 LCP and it is incorporated in the fat blend of the new generation lipid emulsions (LE). Omega-3 LCP have been shown to reduce the expression of genes involved in lipogenesis, which could be important for several organs development. The aim of this study was to ascertain if the use of intravenous FO has an effect on lipogenesis in PI. METHODS: Forty PI were randomized to receive two LE: MSF (50:40:10 Medium Chain Triglycerides (MCT): Soybean oil (SO): FO) or MS (50:50 MCT:SO). We measured plasma lipids on day 7 and the fractional and absolute synthesis rates (FSR and ASR) of cholesterol and of selected fatty acids (FA) after (2)H2O body water labeling. RESULTS: Plasma phospholipids (PL), free cholesterol (FC), and cholesterol esters (CE) concentrations were all lower in MSF than in MS. In spite of lower plasma FC and CE concentrations, cholesterol biosynthesis was similar between the two study groups (FC: FSR 16.0 ± 1.4 vs 14.1 ± 1.1%/d, p = 0.74; ASR 6.8 ± 0.6 vs 7.1 ± 0.6 mg kg(-1) d(-1), p = 0.93; CE: FSR 3.6 ± 0.5 vs 4.2 ± 0.4%/d, p = 0.38; ASR: 3.3 ± 0.4 vs 4.4 ± 0.5 mg kg(-1) d(-1), p = 0.13, in MSF and MS respectively). FSR and ASR of selected FA were, or tended to be, lower in MSF than in MS. ASR of PL palmitate (4.0 ± 0.3 vs 4.8 ± 0.4 mg kg(-1) d(-1), p = 0.045), PL oleate (0.2 ± 0.04 vs 0.4 ± 0.05 mg kg(-1) d(-1), p = 0.02) and CE oleate (0.5 ± 0.1 vs 0.9 ± 0.1 mg kg(-1) d(-1), p = 0.03) were significantly lower in MSF than in MS. There were no differences in plasma TG FA biosynthesis. CONCLUSIONS: Cholesterol biosynthesis was not affected by 10% FO during neonatal parenteral nutrition. Ten percent FO caused a statistically significant reduction in the lipogenesis of selected FA and an overall tendency towards a reduced lipogenesis. The magnitude seems to be limited and the biological significance is unknown. Our data warrant follow-up studies in PI who receive intravenous FO, especially in those infants who receive larger doses than in the present study. Since this trial started in 2007, trial registration was not required.

BACKGROUND & AIMS: Lipid emulsions containing fish oil, as source of long chain omega 3 fatty acids, have recently became available for parenteral nutrition in infants, but scanty data exist in extremely low birth weight preterms. The objective of this study was to compare plasma fatty acids and lipid tolerance in preterm infants receiving different doses of a 15% fish oil vs. a soybean oil based lipid emulsion. METHODS: Preterm infants (birth weight 500-1249 g) were randomized to receive parenteral nutrition with MOSF (30% Medium-chain triglycerides, 25% Olive oil, 30% Soybean oil, 15% Fish oil) or S (S, 100% Soybean oil) both at two levels of fat intake: 2.5 or 3.5 g kg(-1) d(-1), named 2.5Fat and 3.5Fat respectively. Plasma lipid classes and their fatty acid composition were determined on postnatal day 7 and 14 by gas chromatography together with routine biochemistry. RESULTS: We studied 80 infants. MOSF infants had significantly higher plasma phospholipid Docosahexaenoic acid and Eicosapentaenoic and lower Arachidonic acid. Plasma phospholipids, triglycerides and free cholesterol were all significantly higher in the MOSF-3.5Fat group, while cholesterol esters were lower with MOSF than with S. The area under the curve of total bilirubin was significantly lower with MOSF than with S. CONCLUSIONS: The use of a lipid emulsion with 15% FO resulted in marked changes of plasma long-chain fatty acids. Whether the benefits of increasing Docosahexaenoic acid outweigh the potential negative effect of reduced Arachidonic acid should be further studied. MOSF patients exhibited reduced lipid tolerance at 3.5 g kg(-1) d(-1) fat intake. The trial was conducted between January 2008 and December 2012 so we had not registered it in a public trials registry as it is now required for trials that started after July 2008.

BACKGROUND: Elevated plasma phytosterol concentrations are an untoward effect of parenteral nutrition (PN) with vegetable oil-based lipid emulsions (LEs). Phytosterols are elevated in neonatal cholestasis, but the relation remains controversial. OBJECTIVE: The objective was to study the effect of 5 LEs on plasma phytosterols in preterm infants. DESIGN: One hundred forty-four consecutive admitted preterm infants (birth weight: 500-1249 g) were studied. Patients were randomly assigned to receive 1 of 5 different LEs: S [100% soybean oil (SO)], MS [50% medium-chain triglycerides (MCTs) and 50% SO], MSF (50% MCTs, 40% SO, and 10% fish oil (FO)], OS (80% olive oil and 20% SO), or MOSF (30% MCTs, 25% olive oil, 30% SO, and 15% FO). Phytosterols in the LEs and in plasma (on postnatal day 7 and day 14) were measured by gas chromatography-mass spectrometry. RESULTS: Patients in the S group had significantly higher total phytosterol intakes than did the other study groups. On PN days 7 and 14, plasma phytosterol concentrations were highest in the S group and lowest in the MOSF group. Despite similar ß-sitosterol intakes between the MS and MSF groups, plasma concentrations were significantly lower in the MSF than in the MS group. Only 3 patients (2.1%) developed cholestasis: 1 in the MS, 1 in the MSF, and 1 in the MOSF group. No cases of cholestasis were observed in the S and OS groups. CONCLUSIONS: In uncomplicated preterm infants receiving routine PN, we found a correlation between phytosterol intake and plasma phytosterol concentrations; however, cholestasis was rare and no difference in liver function at 6 wk was observed.

UNLABELLED: Acute gastroenteritis (AG) represents both the main cause of acute vomiting in children under 3 years old and a major cause of access to the emergency department. Even if several drugs may be able to reduce the emesis, the pharmacological treatment of vomiting in children remains a controversial issue, and several drugs are prescribed outside their authorized drug label with respect dosage, age, indication, or route of administration and are named as off-label. The aim of present study was to assess the off-label use of antiemetic drugs in patients less than 18 years with vomiting related to AG. This study was carried out in eight pediatric emergency departments in Italy. The following data were obtained crossing the pharmacy distribution records with emergency departments' patient data: sex and age of the patients and detailed information for each drug used (indication, dose, frequency, and route of administration). We recorded that antiemetic drugs were prescribed in every year, particularly in children up to 2 years old, and compared with both literature data and data sheet; 30 % of the administered antiemetics were used off-label. In particular, domperidone was the only antiemetic used labeled for AG treatment in pediatric patients, while metoclopramide and ondansetron have been off-label for both age and indications (i.e., AG treatment). CONCLUSIONS: In conclusion, we documented an off-label use of antiemetics in children, and this could represents a problem of safety for the patient and a legal risk for the prescribing physician if patients have an unwanted or bad outcome from treatment.

OBJECTIVE: To compare plasma lipids in preterm infants given a new lipid emulsion containing 10% fish oil, 50% medium-chain triacylglycerols, and 40% soybean oil, compared with a standard preparation containing 50:50 medium-chain triacylglycerols: soybean oil. STUDY DESIGN: Preterm infants weighing <1250 g at birth (n=47) were randomly assigned to receive parenteral nutrition with a fish oil lipid (n=23) or soybean oil (n=24). Plasma lipid classes and plasma and red blood cell fatty acids were determined by gas chromatography in cord blood and on postnatal days 7 and 14. RESULTS: On day 7, the infants receiving fish oil lipid had significantly lower plasma phospholipids, cholesterol esters, and free cholesterol but similar triglyceride concentrations. They also had significantly higher phospholipid docosahexaenoic acid (2.77 ± 0.08 versus 2.46 ± 0.01 mol%, P<.01) and eicosapentaenoic acid (1.58 ± 0.01 versus 0.25 ± 0.01 mol%, P<.01) as well as lower arachidonic acid (10.64 ± 0.29 versus 11.93 ± 0.29 mol%, P<.01) compared with those receiving soybean oil. Similar differences were found in red blood cells. CONCLUSIONS: The fish oil lipid emulsion was well tolerated, and infants receiving fish oil had lower plasma lipids and improved fatty acids status. The effect of these changes on inflammation, growth, and neurodevelopment should be explored.
