Treatments for multi-system inflammatory syndrome in children - discharge, fever, and second-line therapies.

Scarce evidence exists about the best treatment for multi-system inflammatory syndrome (MIS-C). We analyzed the effects of steroids, intravenous immunoglobulin (IVIG), and their combination on the probability of discharge over time, the probability of switching to second-line treatment over time, and the persistence of fever 2 days after treatment. We did a retrospective study to investigate the effect of different treatments on children with MIS-C from 1 March 2020 to 1 June 2021. We estimated the time-to-event probability using a Cox model weighted by propensity score to balance the baseline characteristics. Thirty of 132 (22.7%) patients were initially treated with steroids alone, 29/132 (21.9%) with IVIG alone, and 73/132 (55%) with IVIG plus steroids. The probability of early discharge was higher with IVIG than with IVIG plus steroids (hazard ratio [HR] 1.65, 95% CI 1.11-2.45, p = 0.013), but with a higher probability of needing second-line therapy compared to IVIG plus steroids (HR 3.05, 95% CI 1.12-8.25, p = 0.028). Patients on IVIG had a higher likelihood of persistent fever than patients on steroids (odds ratio [OR] 4.23, 95% CI 1.43-13.5, p = 0.011) or on IVIG plus steroids (OR 4.4, 95% CI 2.05-9.82, p < 0.001). No differences were found for this endpoint between steroids or steroids plus IVIG.    Conclusions: The benefits of each approach may vary depending on the outcome assessed. IVIG seemed to increase the probability of earlier discharge over time but also of needing second-line treatment over time. Steroids seemed to reduce persistent fever, and combination therapy reduced the need for escalating treatment. What is Known: • Steroids plus intravenous immunoglobulin, compared with intravenous immunoglobulin alone for multi-system inflammatory syndrome (MIS-C) might reduce the need for hemodynamic support and the duration of fever, but the certainty of the evidence is low. What is New: • Intravenous immunoglobulin, steroids, and their combination for MIS-C may have different outcomes. • In this study, intravenous immunoglobulin increased the probability of discharge over time, steroids reduced persistent fever, while combination therapy reduced the need for second-line treatments.

A Case of Toxic Epidermal Necrolysis Secondary to Acetaminophen in a Child.

OBJECTIVE: To report and discuss a serious cutaneous adverse reaction in a child who was treated with acetaminophen (paracetamol). CASE SUMMARY: A five years old male child presented a pruriginous maculopapular rash and a "drug-induced Stevens-Johnson syndrome/Toxic Epidermal Necrolysis" was suspected. Applying Spanish Pharmacovigilance System probability algorithm (modified Karch-Lasagna algorithm) for the suspected drugs (acetaminophen, ibuprofen and azithromycin), the causality of this adverse reaction was possible for acetaminophen and unlikely for the other two drugs. In this case it was recommended suspending and avoiding treatment with acetaminophen. This adverse reaction was reported to the Spanish Pharmacovigilance System (notification number: 10-600428). DISCUSSION: Skin adverse reactions induced by drugs are uncommon but often serious and potentially fatal. There are few cases reports of "Stevens-Johnson syndrome/Toxic Epidermal Necrolysis" associated with acetaminophen in the literature. We present a documented case in a child. According to modified Karch-Lasagna algorithm, this case represents a possible adverse reaction. CONCLUSION: Hypersensitivity reactions with skin involvement are rarely associated with acetaminophen ingestion, but in a population such as the paediatric population, in which its use is widespread, the involvement of this drug should always be suspected if no other possible cause at sight.

Después del proceso terapéutico: ¿curación, recaída o recidiva? / After of therapeutic process: cure, relapsed?

Los autores centran su ensayo en torno a la necesidad de establecer criterios de curación, mejoría, restablecimiento, recaída, recidiva y fracaso terapéutico en el trabajo con farmacodependiente. Establecen los criterios que al respecto orientan el tratamiento, la rehabilitación y la reincorporación social en la Unidad de Atención al Farmacodependiente del Hospital Psiquiátrico de Caracas
