Assessment of catabolic state in infants with the use of urinary titin N-fragment. Pediatr Res 2022; 91:1748-1753. [PMID: 34274960 DOI: 10.1038/s41390-021-01658-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 06/30/2021] [Accepted: 07/02/2021] [Indexed: 11/09/2022]
Abstract
BACKGROUND Urinary titin N-fragment levels have been used to assess the catabolic state, and we used this biomarker to evaluate the catabolic state of infants. METHODS We retrospectively measured urinary titin N-fragment levels of urinary samples. The primary outcome was its changes according to postmenstrual age. The secondary outcomes included differences between gestational age, longitudinal change after birth, influence on growth, and relationship with blood tests. RESULTS This study included 219 patients with 414 measurements. Urinary titin N-fragment exponentially declined with postmenstrual age. These values were 12.5 (7.1-19.6), 8.1 (5.1-13.0), 12.8 (6.0-21.3), 26.4 (16.4-52.0), and 81.9 (63.3-106.4) pmol/mg creatinine in full, late, moderate, very, and extremely preterm infants, respectively (p < 0.01). After birth, urinary levels of titin N-fragment exponentially declined, and the maximum level within a week was associated with the time to return to birth weight in preterm infants (ρ = 0.39, p < 0.01). This was correlated with creatine kinase in full-term infants (ρ = 0.58, p < 0.01) and with blood urea nitrogen in preterm infants (ρ = 0.50, p < 0.01). CONCLUSIONS The catabolic state was increased during the early course of the postmenstrual age and early preterm infants. IMPACT Catabolic state in infants, especially in preterm infants, was expected to be increased, but no study has clearly verified this. In this retrospective study of 219 patients with 414 urinary titin measurements, the catabolic state was exponentially elevated during the early postmenstrual age. The use of the urinary titin N-fragment clarified catabolic state was prominently increased in very and extremely preterm infants.

Abstract
The concept of the developmental origins of health and disease (DOHaD) views unfavorable perinatal circumstances as contributing to the development of diseases in later life. It is well known that such unfavorable circumstances play an important role as a risk factor for chronic kidney disease (CKD) in infants born with prematurity. Low birthweight (LBW) is believed to be a potential contributor to CKD in adulthood. Preterm and/or LBW infants are born with incomplete nephrogenesis. As a result, the number of nephrons is low. The poor intrauterine environment also causes epigenetic changes that adversely affect postnatal renal function. After birth, hyperfiltration of individual nephrons due to low nephron numbers causes proteinuria and secondary glomerulosclerosis. Furthermore, the risk of CKD increases as renal damage takes a second hit from exposure to nephrotoxic substances and acquired insults such as acute kidney injury after birth among infants in neonatal intensive care. Meanwhile, unfortunately, recent studies have shown that the number of nephrons in healthy Japanese individuals is approximately two-thirds lower than that in previous reports. This means that Japanese premature infants are clearly at a high risk of developing CKD in later life. Recently, several DOHaD-related CKD studies from Japanese researchers have been reported. Here, we summarize the relevance of CKD in conjunction with DOHaD and review recent studies that have examined the impact of the upward LBW trend in Japan on renal health.

The Secretive Liaison of Particulate Matter and SARS-CoV-2. A Hypothesis and Theory Investigation. Front Genet 2020; 11:579964. [PMID: 33240326 PMCID: PMC7680895 DOI: 10.3389/fgene.2020.579964] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Accepted: 09/11/2020] [Indexed: 12/29/2022] Open
Abstract
As the novel coronavirus disease sweeps across the world, there is growing speculation on the role that atmospheric factors may have played on the different distribution of SARS-CoV-2, and on the epidemiological characteristics of COVID-19. Knowing the role that environmental factors play in influenza virus outbreaks, environmental pollution and, in particular, atmospheric airborne (particulate matter, PM) has been considered as a potential key factor in the spread and mortality of COVID-19. A possible role of the PM as the virus carrier has also been debated. The role of PM in exacerbating respiratory and cardiovascular disease has been well recognized. Accumulating evidence support the hypothesis that PM can trigger inflammatory response at molecular, cellular and organ levels. On this basis, we developed the hypothesis that PM may play a role as a booster of COVID-19 rather than as a carrier of SARS-CoV-2. To support our hypothesis, we analyzed the molecular signatures detected in cells exposed to PM samples collected in one of the most affected areas by the COVID-19 outbreak, in Italy. T47D human breast adenocarcinoma cells were chosen to explore the global gene expression changes induced by the treatment with organic extracts of PM 2.5. The analysis of the KEGG's pathways showed modulation of several gene networks related to the leucocyte transendothelial migration, cytoskeleton and adhesion system. Three major biological process were identified, including coagulation, growth control and immune response. The analysis of the modulated genes gave evidence for the involvement of PM in the endothelial disease, coagulation disorders, diabetes and reproductive toxicity, supporting the hypothesis that PM, directly or through molecular interplay, affects the same molecular targets as so far known for SARS-COV-2, contributing to the cytokines storm and to the aggravation of the symptoms triggered by COVID-19. We provide evidence for a plausible cooperation of receptors and transmembrane proteins, targeted by PM and involved in COVID-19, together with new insights into the molecular interplay of chemicals and pathogens that could be of importance for sustaining public health policies and developing new therapeutic approaches.
