Portuguese Consensus on Acute Porphyrias: Diagnosis, Treatment, Monitoring and Patient Referral

Acute porphyrias are a group of rare genetic metabolic disorders, caused by a defect in one of the enzymes involved in the heme biosynthesis, which results in an abnormally high accumulation of toxic intermediates. Acute porphyrias are characterized by potentially life-threatening attacks and, for some patients, by chronic manifestations that negatively impact daily functioning and quality of life. Clinical manifestations include a nonspecific set of gastrointestinal, neuropsychiatric, and/or cutaneous symptoms. Effective diagnostic methods are widely available, but due to their clinical heterogeneity and non-specificity, many years often elapse from symptom onset to diagnosis of acute porphyrias, delaying the treatment and increasing morbidity. Therefore, increased awareness of acute porphyrias among healthcare professionals is paramount to reducing disease burden. Treatment of acute porphyrias is centered on eliminating the potential precipitants, symptomatic treatment, and suppressing the hepatic heme pathway, through the administration of hemin or givosiran. Moreover, properly monitoring patients with acute porphyrias and their relatives is fundamental to preventing acute attacks, hospitalization, and long-term complications. Considering this, a multidisciplinary panel elaborated a consensus paper, aiming to provide guidance for an efficient and timely diagnosis of acute porphyrias, and evidence-based recommendations for treating and monitoring patients and their families in Portugal. To this end, all authors exhaustively reviewed and discussed the current scientific evidence on acute porphyrias available in the literature, between November 2022 and May 2023.

Association Between Weekend and Holiday Admission with Pneumonia and Mortality in a Tertiary Center in Portugal: A Cross-Sectional Study

INTRODUCTION

Acute bacterial pneumonia is a common and potentially fatal disease where early recognition and treatment are crucial. Increasing medical literature suggests worse outcomes in patients admitted for medical and surgical conditions during the weekend. Little is known about this effect in patients with acute bacterial pneumonia. Obective: The aim of this study was to evaluate the impact of weekend and holiday hospital admission on the outcomes of acute bacterial pneumonia.

MATERIAL AND METHODS

Retrospective analysis of adult patients (> 18 years) with acute bacterial pneumonia collected from a tertiary referral center database. Length of stay, total cost, admission to intensive care unit, development of sepsis and organ failure, and mortality were compared between patients admitted on a weekday and patients admitted during a weekend or holiday.

RESULTS

We analyzed 53 854 hospital admissions from 42 512 patients (median age 84.0 years, range 18 - 118 years), corresponding to 30 554 admissions during weekdays, 21 222 at weekends and 2078 during public holidays. Weekend and holiday admission was not associated with increased costs, length of stay, intensive care unit admission, development of sepsis, organ failure, and mortality.

CONCLUSION

A weekend/holiday effect in acute bacterial pneumonia was not evident in our series.
