[PMID: 39147906 DOI: 10.1038/s41390-024-03482-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 07/24/2024] [Accepted: 07/25/2024] [Indexed: 08/17/2024]
Abstract
BACKGROUND Rapidly progressive necrotizing enterocolitis (RP-NEC) is a particular subtype of NEC known for its rapid progression and high mortality rate. The objective of this study was to establish a predictive model for RP-NEC. METHODS This was a retrospective single-center cohort study. Patients were newborn infants with NEC (Bell's stage ≥ IIB) admitted from January 1, 2016 to December 31, 2023. The primary outcome was RP-NEC defined as the need for surgical intervention and/or death within 48 hours of the onset of NEC. RESULTS Totally 334 newborn infants were included, among which 82 (24.6%) were RP-NEC cases with a gestation age 34.1 (31.0, 37.0) weeks and birth weight 2100 (1413, 2800) g. Plasma sodium <135 mmol/L, C-reactive protein ≥10 mg/L, platelet count <100 × 109/L, lymphocyte count <1.5 × 109/L, pH <7.2 in blood gas, and ascites at NEC onset were identified as independent risk factors for RP-NEC. The model established presented an AUC value of 0.983 (95% CI 0.97-0.99). The calibration curve for validation was applied revealing a slope close to unity while the Hosmer-Lemeshow test yielded χ2 = 2.550 (p = 0.636). CONCLUSION The predictive model established on the above 6 items of RP-NEC is highly promising. IMPACT Currently, there is a paucity of research on this specific type of severe necrotizing enterocolitis (NEC) characterized by rapid progression. Our study was to investigate the risk factors associated with surgical intervention and/or death within 48 hours following onset in infants with NEC, establish a predictive model for infants with rapidly progressive NEC. The new data presented in this study was the ROC curve combining the above factors as well as hyponatremia.

Abstract
AIM There is limited literature available about necrotising enterocolitis (NEC) in low- and middle-income countries. This study sought to determine the proportion, pattern and risk factors for mortality among very low birth weight (VLBW) neonates with NEC in a middle-income setting. METHODS A retrospective observational cohort study was conducted on all infants with birth weights less than 1501 g admitted from 2018 to 2020 at Groote Schuur Hospital, Cape Town, South Africa. Data were obtained from the Vermont Oxford Network and hospital folders. RESULTS A total of 104/1582 (6.6%) neonates were diagnosed with NEC with a median onset of 8 days of life. The mortality rate was 39.0%, compared to the all-cause mortality rate of 18.7% for VLBW neonates. Thirty-two (32.0%) neonates with NEC were transferred for surgery of whom 10 (31.3%) died. Small for gestational age (p = 0.13), NEC stage 2B or above (p = 0,002), a positive blood culture (p = 0.018), a raised C-reactive protein (p = 0.013), hyponatraemia (p = 0.004), anaemia requiring blood transfusion (p = 0.003) and thrombocytopenia requiring platelet transfusion (p = 0.033) were associated with mortality. A positive blood culture was found in 37.0% with a predominance of Klebsiella pneumoniae isolates. CONCLUSION NEC has an early onset and a high mortality rate in our setting.

[PMID: 38177247 DOI: 10.1038/s41390-023-02999-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/07/2023] [Accepted: 12/11/2023] [Indexed: 01/06/2024]
Abstract
BACKGROUND This study aimed to investigate gestational age-specific hematological features in preterm infants with necrotizing enterocolitis (NEC) and identify predictive hematological biomarkers for surgical NEC. METHODS We conducted a retrospective study comparing gestational age (GA)-specific clinical data between medical NEC (m-NEC) and surgical NEC (s-NEC) subgroups, stratified by GA as <28 weeks, 28 ≤ GA < 32 weeks, and 32 ≤ GA < 37 weeks. Multivariate logistic analysis and receiver operating characteristic curve were used to identify the independent predictors of s-NEC. RESULTS In comparison to m-NEC at NEC onset, s-NEC infants exhibited the following findings: In GA < 28 weeks, s-NEC infants had lower platelet counts. In 28 ≤ GA < 32 weeks, lower absolute lymphocyte counts, and significant percent drop in platelets, lymphocytes, and monocytes were observed. In 32 ≤ GA < 37 weeks, lower absolute lymphocyte counts and significant percent drop in lymphocytes were found. Independent predictors were able to distinguish s-NEC from m-NEC. The area under the curve (AUC) for platelet counts in GA < 28 weeks was 0.880, while C-reactive protein in 28 ≤ GA < 32 weeks had an AUC of 0.889. The AUC for lymphocyte counts in 32 ≤ GA < 37 weeks was 0.892. CONCLUSION This study identified hematological abnormalities in the development of NEC based on gestational age. Independent predictors may help clinicians distinguish surgical NEC from medical NEC. IMPACT Necrotizing enterocolitis (NEC) patients with different gestational ages (GA) exhibit different hematological features and independent predictors of surgical NEC differ among different GAs. Our research made the current studies about peripheral hematological features with NEC more complete by analyzing peripheral data collected within 24 h of birth, at day 5-7, day 3-4, day 1-2 before NEC onset, at the time of NEC onset, day 1, day 2, day 3, day 4-5, day 6-7 after NEC onset. Our study is helpful to clinicians in developing a more detailed diagnostic strategy based on GA for the early identification of surgical NEC.

Abstract
The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.
