Multiple pregnancies are more frequently associated with adverse maternal and neonatal outcomes. The incidence of multiple pregnancies has increased with the use of assisted reproductive technologies (ART): they account for between 15% and 25% of twin births. ART has also been associated with adverse outcomes in both singleton and multiple pregnancies, although the available evidence is limited and heterogeneous. Objective. To evaluate maternal and perinatal outcomes in spontaneously conceived twin pregnancies and compare them with those conceived through ART. Population and methods. Patients aged 18 years or older with twin pregnancies who reached a gestational age of 24.0 weeks and who underwent first-trimester screening, follow-up, and delivery at the Hospital Italiano de Buenos Aires between January 2014 and December 2022. A composite outcome of maternal and neonatal adverse events was analyzed. Neurological development was monitored until age 2. Results. A total of 243 twin pregnancies were included (148 ART; 95 spontaneous). The ART group had a higher prevalence of advanced maternal age, nulliparity, obesity, and chronic diseases, with statistically significant differences (p <0.001). There were no significant differences in primary maternal outcomes (29% vs. 23%; p = 0.347) or neonatal outcomes (16% vs. 19%; p = 0.371). We found an increased frequency of autism spectrum disorders in pregnancies conceived through ART. Conclusion. Twin pregnancies resulting from ART showed similar maternal and neonatal outcomes to those resulting from spontaneous conception, despite significant differences in baseline maternal characteristics. Long-term follow-up studies are needed.","PeriodicalId":8338,"journal":{"name":"Archivos argentinos de pediatria","volume":" ","pages":"e202510997"},"PeriodicalIF":0.5,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148026167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present the case of a 2-year-old boy with severe bone marrow aplasia and septic shock who required ECMO as a bridge to hematopoietic stem cell transplantation. High-flow venoarterial support was initiated, initially without anticoagulation, due to marked thrombocytopenia and a high risk of bleeding. A multidisciplinary discussion was held involving the treating medical team and the institutional Ethics Committee. The patient was successfully weaned from support, showed favorable clinical progress until receiving the transplant, and achieved effective hematopoietic recovery.

Pneumocystis jirovecii pneumonia (PJP) is a life-threatening infection that affects patients with impaired immunity (primarily cellular immunity). Given that few studies have evaluated the incidence of PJP in pediatric patients with solid tumors, the objective of this study was to estimate the incidence of PJP among pediatric patients with solid tumors treated at a general hospital. Population and methods. A retrospective cohort study of 251 patients under 18 years of age with a confirmed diagnosis of solid organ cancer treated at a general hospital. Clinical, oncological, and infectious disease characteristics were evaluated. The cumulative incidence and incidence density of PJP were calculated, along with their respective 95% confidence intervals. Results. The cumulative incidence of PJP was 2.4% (95%CI 0.9-5.1), with an incidence rate of 8.4 cases per 1000 person-years (95%CI 3.8-18.6), and a median time from cancer diagnosis to infection of 2.7 months (IQR 2-4.5)-most patients presented with moderate symptoms. Conclusion. PJP can occur in children and adolescents with solid tumors, although its incidence is low and the prognosis is generally favorable in this cohort. These findings provide important insights into the risk profile in this population and highlight the need for further studies to determine its clinical impact and the role of prophylaxis.","PeriodicalId":8338,"journal":{"name":"Archivos argentinos de pediatria","volume":" ","pages":"e202510972"},"PeriodicalIF":0.5,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148148265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hematopoietic stem cell transplantation (HSCT) represents a key and potentially curative treatment option for selected patients with IEI. Nevertheless, HSCT is a complex procedure associated with clinical and immunological complications that may arise at different stages during post-transplant follow-up. This article summarizes the consensus recommendations developed by the Pediatric Immunology Work Group of the Sociedad Argentina de Pediatría, in collaboration with transplant specialists, regarding the essential principles for clinical and immunological evaluation of patients with IEI after HSCT.
