Improving Drug Safety in Pediatric and Young Adult Patients with Hemato-Oncological Diseases: A Prospective Study of Active Pharmacovigilance.

The acquisition of relevant pediatric clinical safety data is essential to ensure tolerable drug therapies. Comparing the real number of Adverse Drug Reaction (ADR) reports in clinical practice with the literature, the idea of ADR underreporting emerges. An active pharmacovigilance observational prospective study was conducted to assess the safety of oncology pharmacological prescriptions in patients aged 0-24 years at Institute for Maternal and Child Health IRCCS Burlo Garofolo in Trieste and IRCCS CRO National Cancer Institute in Aviano (Italy) between January 2021 and October 2023. Prescriptions and ADRs were evaluated by a multidisciplinary team. A total of 1218 prescriptions for 38 patients were analyzed, and 190 ADRs of grade 3-5 were collected. As compared to historical data, we registered a significant increase (p < 0.001) in the number of ADRs. The risk of ADR was 3.4 times higher in the case of off-label prescriptions compared to on-label ones (OR 3.4; [1.47; 7.89]; p-value = 0.004). The risks of error and near-miss were reported for 6.3% and 18.2% of total prescriptions, respectively. Of the total of 133 interactions, 47 (35.3%) resulted in ADRs. This study shows the importance of pro-active pharmacovigilance to efficiently highlight ADRs, and the fundamental role of multidisciplinary teams (oncologist, pharmacist, pharmacologist, pediatrician, nurse) in improving patients' safety during therapy.

Gestational diabetes mellitus: Impact of adherence on patient management and maternal-neonatal complications.

BACKGROUND: Gestational diabetes mellitus is a form of diabetes whose prevalence is constantly increasing, thus leading to a growth in the necessary resources and organization of diabetes and obstetric facilities. The literature suggests that adherence to diet and therapy in patients with GDM might be highly variable and only sometimes optimal, and that this suboptimal compliance might be associated with more complicated treatment management or some adverse perinatal outcomes. This study evaluates this adherence and the benefits of constant blood glucose monitoring regarding maternalneonatal complications. METHODS: We conducted a multicentre prospective observational study, including all patients diagnosed with gestational diabetes mellitus and aged ≥ 18 years, between January 2019 and November 2021. We measured patients' adherence by clinical diary monitoring (medical evaluation) and observation of data obtained from glycaemic control (glucometer analysis). Patients were divided into three groups the adherent patient group, the non-adherent patient group and the partially adherent patient group; then, we compared the groups to assess the impact of non-adherence on patients' health. RESULTS: 122 (46.9 %) were classified in the adherent group (AG), 91 (35.0 %) in the partially adherent group (PG), and 47 (18.1 %) in the non-adherent group (NG) out of a population of 260 patients. The AG and PG groups were associated with a RRR of 74 % (95 % CI:0.13-1.03, p = 0.057) and 32 % (95 % CI:0.25-1.84, p = 0449) in operative delivery, respectively. Finally, this study proved that full or partial adherence is associated with decreased insulin administration during labour in 67 % (OR=0.33 p = 0.038). CONCLUSION: The study showed that patients' adherence to diet and/or therapy proposed by the diabetologist could significantly influence optimal glycaemic control during pregnancy Better compliance may lead to a lower incidence of operative deliveries and insulin utilization during pregnancy and labour.

Compounded Effervescent Magnesium for Familial Hypomagnesemia: A Case Report.

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive disorder affecting <1/1,000,000 people. It is caused by mutations in the CLDN16 (FHHNC Type 1) or CLDN19 (FHHNC Type 2) genes, which are located on Chromosomes 3q27 and 1p34.2, respectively. There are no drug therapies for this condition. Although magnesium salts represent an important class of compounds and exhibit various therapeutic actions as a supplement for magnesium deficiency in FHHNC, various formulations on the market have different bioavailability. We report the case of a patient with FHNNC first treated, in our Pediatric Institute, with high doses of magnesium pidolate and magnesium and potassium citrate. The patient began to neglect this therapy after experiencing frequent daily episodes of diarrhoea. Our pharmacy received a request for an alternative magnesium supplement that would better comply by ensuring a good magnesium intake which will result in adequate blood magnesium levels. In response, we developed a galenic compound in the form of effervescent magnesium. Here, we report on the promise of this formulation not only for better compliance than pidolate, but also for better bioavailability.
