Intralipid (Fresenius Kabi) was the most commonly used lipid emulsion in parenteral nutrition (PN), with a 100% soybean oil composition, a low vitamin E content, and a ω-6: ω-3 ratio of 7:1. A recent alternative formulation is SMOFlipid (Fresenius Kabi), with a ω-6: ω-3 ratio of 5:2 and higher vitamin E content. A retrospective observational study was conducted to determine neonatal morbidity in very low birth weight (VLBW) premature infants during two periods: P1, when PN was based exclusively on Intralipid, and P2, when only SMOFlipid was supplied. In total, 170 VLBW neonates were analyzed, of whom 103 received PN for more than 6 days, 56 during P1, and 47 during P2. In both periods, the antenatal and neonatal characteristics of the cohort were comparable. In this analysis, the prevalence of associated comorbidities was determined. During P2, there were fewer cases of moderate to severe bronchopulmonary dysplasia (BPD) and of cholestasis, but more cases of late sepsis, mainly Staphylococcus epidermidis. No changes in the prevalence of other neonatal comorbidities were observed. We believe that the SMOFlipid used in PN could discreetly improve the prevalence of cholestasis or BPD.

We observed a severe case of cerebral toxoplasmosis in a 22‐year‐old woman diagnosed with dermatomyositis in 2016 in Venezuela, and treated with rituximab and azathioprine. The patient met clinical and microbiological criteria. Treatment with pyrimethamine and sulfadiazine was initiated, and the patient was discharged. She was rehospitalized with signs and symptoms of a manic episode. During hospitalization, the patient developed acute kidney injury related to sulfadiazine crystalluria. Finally, acute kidney injury was resolved and the patient was successfully discharged.
