Abstract
Infection is an important cause of death during infancy worldwide and is a frequent etiology of sudden unexpected death in infancy (SUDI). Procalcitonin (PCT) is a useful marker to diagnose infection in patients, and several studies report the stability of PCT after death. The added value of a biological marker, such as the PCT level in the blood, remains controversial in investigating SUDI. The aim of this study was to determine if PCT can help clinicians determine whether infection caused SUDI. We conducted a retrospective, multicenter study with the French SUDI registry (Observatoire National des Morts Inattendues du Nourrisson; OMIN). We collected data from this registry on children who died between May 2015 and June 2021. The levels of PCT in the blood of 540 SUDI patients were measured. We compared PCT and other biological tests performed in terms of infection status, autopsy results, and cause of death using clinical and biological data compiled by pediatricians at the SUDI referral center. PCT levels were significantly higher in the children who died from infection than in those who did not (0.12 µg/L vs. 0.08 µg/L, p < 0.001). A PCT blood level exceeding 0.2 µg/L was more frequently observed when infection was present than in the absence of infection (44.3% vs. 15.4%, p < 0.001). The same data were obtained with a 0.5 µg/L cut-off (36.1% with infection vs. 9.2% without, p < 0.001). Conclusions: PCT is a sensitive biomarker for detecting infections postmortem; thus, additional samples may be necessary during autopsy. What is known: • PCT is a stable marker postmortem and increases earlier than CRP, i.e., 2-4 h after the beginning of an infection vs. 6 h. • PCT can be measured up to 140 h after death. What is new: • PCT is a sensitive marker for detecting infection in SUDI patients postmortem. • This test can reveal an infection from non-standardized samples obtained during autopsy if such an infection was not determined before death.

Procalcitonin and Adrenomedullin in Infectious Diseases. MICROBIOLOGY RESEARCH 2023.

Abstract
Calcitonin (CT) and adrenomedullin (ADM) are members of the CT family. Procalcitonin (PCT) is a prohormone of CT. Elevations in serum PCT and ADM levels are associated with severe sepsis and coronavirus disease 2019 (COVID-19). PCT enhances sepsis mortality and it binds to the CGRP receptor, which is a heterodimer of CT receptor-like receptor and receptor activity-modifying protein 1. The N-terminal truncated form of PCT, PCT3-116, is produced by the cleavage of PCT by dipeptidyl peptidase 4 (DPP-4) and is the main form of PCT in serum during sepsis, inducing microvascular permeability. Mid-regional pro-adrenomedullin (MR-proADM) is used instead of ADM as a biological indicator because ADM is rapidly degraded, and MR-proADM is released at the same rate as ADM. ADM reduces endothelial permeability and promotes endothelial stability. Endothelial dysfunction is responsible for multiple organ failure in sepsis and COVID-19 patients. Therefore, ADM may be an important molecule for improving the severity associated with sepsis and COVID-19. This review focuses on the current knowledge of PCT and ADM in sepsis and COVID-19.

Abstract
Background: Recent guidelines recommend avoiding venipuncture to prevent lymphedema for breast cancer patients. This study investigated whether single or multiple sterile venipuncture procedures develop a systemic inflammation or infection and increase lymphedema in the rabbit ear lymphedema model. Methods and Results: Eighteen New Zealand white female rabbits were included. The right ear lymphedema model was created by surgical procedure; then, rabbits were divided into three randomized groups. Single and multiple venipuncture procedures were applied at least the 60th day after surgery for Group I and II, respectively. Group III was a control group. C-reactive protein (CRP) and procalcitonin (PCT) levels were analyzed to determine inflammation and infection. Ear thickness measurements were applied using a vernier caliper to assess the differences in lymphedema between the ears. All rabbits were euthanized on the 90th day after surgery. Histopathological analysis was performed to evaluate lymphedema by measuring tissue thicknesses. Ear thickness measurements showed that ear lymphedema was developed and maintained with surgical operation in all groups (p < 0.05). There was no difference in the ear thickness measurements between and within-groups results (p > 0.05). CRP and PCT levels were below the lower detection levels in all groups. According to the differences of histopathological ear distances, there were significant differences within-groups for all groups (p < 0.05), and no differences were identified between groups (p > 0.05). Conclusion: This experimental study demonstrated that single or multiple sterile venipuncture procedures did not trigger infection or inflammation and did not exacerbate ear lymphedema in the rabbit ear lymphedema model.

[PMID: 31661804 PMCID: PMC6963620 DOI: 10.3390/antibiotics8040199] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2019] [Revised: 10/18/2019] [Accepted: 10/25/2019] [Indexed: 12/11/2022] Open
Abstract
Sepsis is a leading cause of morbidity and mortality worldwide. It is defined as the presence of a Systemic Inflammatory Response Syndrome, and it represents a significant burden for the healthcare system. This is particularly true when it is diagnosed in the setting of nosocomial infections, which are usually a matter of concern with regard to medical liability being correlated with increasing economic costs and people's loss of trust in healthcare. Hence, the Italian governance promotes the clinical risk management with the aim of improving the quality and safety of healthcare services. In this context, the role of medico-legal experts working in a hospital setting is fundamental for performing autopsy to diagnose sepsis and link it with possible nosocomial infections. On the other hand, medico-legal experts are party to the clinical risk management assessment, and deal with malpractice cases and therefore contribute to formulating clinical guidelines and procedures for improving patient safety and healthcare providers' work practices. Due to this scenario, the authors here discuss the role of medico-legal experts in Italy, focusing on sepsis and nosocomial infections.
