ABSTRACT

Purpose@#The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) is considered a predictive marker of preeclampsia. However, the relationship between the sFlt-1/PlGF ratio and perinatal and neonatal outcomes remains unknown. This study aimed to determine the associations of the sFlt-1/PlGF ratio with perinatal and neonatal outcomes in newborns born to mothers with preeclampsia. @*Methods@#This retrospective cohort study reviewed singleton neonates born to mothers with preeclampsia who underwent testing for the sFlt-1/PlGF ratio. We investigated the relationship between maternal sFlt-1/PlGF ratios and gestational age (GA), birth weight (Bwt), Bwt z-score, morbidities, and mortality of neonates born to mothers tested for the sFlt-1/PlGF ratio. Maternal sFlt-1/PlGF ratios examined within 30 days before delivery were used for analysis. Neonatal morbidities and mortality were investigated only in preterm infants born earlier than 32 weeks GA. @*Results@#A total of 225 neonates were included, of which 163 (72.4%) were preterm infants. GA (R=– 0.577, p<0.001), Bwt (R=–0.713, p<0.001), and Bwt z-score (R=–0.608, p<0.001) exhibited significant negative correlations with the sFlt-1/PlGF ratios. Among the 50 preterm infants born earlier than 32 weeks GA, neonatal morbidities were not significantly associated with the sFlt-1/PlGF ratio after adjusting for GA and Bwt. @*Conclusion@#In mothers with preeclampsia, a higher sFlt-1/PlGF ratio was associated with the delivery of newborns with lower GA and lower Bwt. However, this ratio was not associated with increased morbidity or mortality in premature infants born earlier than 32 weeks GA.

ABSTRACT

Background@#This study aimed to compare the occurrence of adverse events (AEs) and disease flares after vaccination against coronavirus disease 2019 (COVID-19) and influenza in patients with autoimmune rheumatic diseases (ARDs). @*Methods@#Between November 2021 and March 2022, a survey was conducted among patients with ARD who received COVID-19 and influenza vaccinations. The questionnaire included 11 mandatory and closed-ended questions, and the following items were collected: medical history, immunization history, type of vaccine, patient-reported AEs, flare-up of the underlying disease after vaccination, and a confirmed diagnosis of COVID-19 or influenza. We compared the occurrence of vaccine-related adverse reactions to the COVID-19 and influenza vaccines based on the survey results. Multivariate logistic regression analysis was used to identify the factors affecting AEs or disease flares and to compare the post-vaccine response to mixed and matched vaccines. @*Results@#We analyzed 601 adults with ARD who received the COVID-19 vaccine, with a mean age of 49.6 years (80.5% female). A total of 255 participants (42.4%) received a complete course of primary vaccination, 342 (56.9%) completed the booster dose, and 132 (38.6%) received a mixed vaccine. The frequencies of AEs (188 [52.2%] vs. 21 [5.8%]; P< 0.001) and disease flares (58 [16.2%] vs. 5 [1.4%]; P < 0.001) after COVID-19 vaccination were significantly higher than those after influenza vaccination. In the risk factor analysis, previous allergic reaction to other vaccines (odds ratio, 1.95; confidence interval, 1.07–3.70; P = 0.034) was the only factor associated with the occurrence of AEs. There was no difference in the post-vaccine responses between the mixed and matched vaccines. @*Results@#We analyzed 601 adults with ARD who received the COVID-19 vaccine, with a mean age of 49.6 years (80.5% female). A total of 255 participants (42.4%) received a complete course of primary vaccination, 342 (56.9%) completed the booster dose, and 132 (38.6%) received a mixed vaccine.

ABSTRACT

Vascular wall-resident stem cells (VW-SCs) play a critical role in maintaining normal vascular function and regulating vascular repair. Understanding the basic functional characteristics of the VW-SCs will facilitate the study of their regulation and potential therapeutic applications. The aim of this study was to establish a stable method for the isolation, culture, and validation of the CD34+ VW-SCs from mice, and to provide abundant and reliable cell sources for further study of the mechanisms involved in proliferation, migration and differentiation of the VW-SCs under various physiological and pathological conditions. The vascular wall cells of mouse aortic adventitia and mesenteric artery were obtained by the method of tissue block attachment and purified by magnetic microbead sorting and flow cytometry to obtain the CD34+ VW-SCs. Cell immunofluorescence staining was performed to detect the stem cell markers (CD34, Flk-1, c-kit, Sca-1), smooth muscle markers (SM22, SM MHC), endothelial marker (CD31), and intranuclear division proliferation-related protein (Ki-67). To verify the multipotency of the isolated CD34+ VW-SCs, endothelial differentiation medium EBM-2 and fibroblast differentiation medium FM-2 were used. After culture for 7 days and 3 days respectively, endothelial cell markers and fibroblast markers of the differentiated cells were evaluated by immunofluorescence staining and q-PCR. Furthermore, the intracellular Ca2+ release and extracellular Ca2+ entry signaling were evaluated by TILLvisION system in Fura-2/AM loaded cells. The results showed that: (1) High purity (more than 90%) CD34+ VW-SCs from aortic adventitia and mesenteric artery of mice were harvested by means of tissue block attachment method and magnetic microbead sorting; (2) CD34+ VW-SCs were able to differentiate into endothelial cells and fibroblasts in vitro; (3) Caffeine and ATP significantly activated intracellular Ca2+ release from endoplasmic reticulum of CD34+ VW-SCs. Store-operated Ca2+ entry (SOCE) was activated by using thapsigargin (TG) applied in Ca2+-free/Ca2+ reintroduction protocol. This study successfully established a stable and efficient method for isolation, culture and validation of the CD34+ VW-SCs from mice, which provides an ideal VW-SCs sources for the further study of cardiovascular diseases.

ABSTRACT

ObjectiveTo explore the effect and mechanism of Zuojinwan (ZJW) in the treatment of ulcerative colitis (UC) through network pharmacology and experimental validation. MethodUsing network pharmacology and molecular docking, the active components and potential mechanism of ZJW in treating UC were preliminarily identified. Forty-eight male C57BL/6J mice were randomly divided into a normal group, a model group, a sulfasalazine group (300 mg·kg-1), and low-, medium-, and high-dose ZJW groups (1.82, 3.64, 7.28 g·kg-1). The UC model was induced by dextran sulfate sodium (DSS), and oral administration of drugs began on the third day of modeling, lasting for 7 days. The general condition of mice was observed daily, and the disease activity index (DAI) was evaluated. Hematoxylin-eosin (HE) staining was performed to observe histopathological changes in colon tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-10 in mouse serum. The molecular mechanism was validated using Western blot. ResultNetwork pharmacology predicted that the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway might be a key pathway in the regulation of UC by ZJW. Molecular docking results showed good binding ability between the key components of ZJW and core targets. Animal experiment results showed that compared with the normal group, the model group had shortened colon length (P<0.01), increased DAI scores, spleen index, colon tissue pathology scores, and levels of TNF-α and IL-6 in serum (P<0.05, P<0.01), increased PI3K, phosphorylated Akt (p-Akt), and B-cell lymphoma-2 (Bcl-2)-associated X protein (Bax) expression in colon tissue (P<0.05, P<0.01), and decreased serum IL-10 levels and colon tissue Bcl-2 protein expression (P<0.01). Compared with the model group, the ZJW groups showed significant improvement in UC symptoms, relieved colon tissue pathological damage, downregulated levels of inflammatory cytokines TNF-α and IL-6 in serum (P<0.01), inhibited expression of PI3K, p-Akt, and Bax proteins in colon tissue (P<0.05, P<0.01), and increased serum IL-10 levels and colon tissue Bcl-2 protein expression (P<0.01), with the high-dose group showing the best effect. ConclusionZJW effectively alleviates DSS-induced UC, and its mechanism may be related to the inhibition of the PI3K/Akt signaling pathway and regulation of apoptosis-related protein expression.

ABSTRACT

Purpose@#Extremely preterm infants are prone to brain injury and underdevelopment. Intraventricular hemorrhage (IVH) is the most common cause of brain injury and a significant risk factor for neurodevelopmental delay in preterm infants. Severe IVH is known to have a poor outcome; however, the outcomes of low-grade IVH remain controversial. This study aimed to evaluate neurodevelopmental outcomes and brain segmental volumes of preterm infants with low-grade IVH. @*Methods@#This retrospective cohort study included 109 extremely preterm infants who underwent term equivalent age-magnetic resonance imaging and neurodevelopmental evaluation at a corrected age of 18 to 24 months. We compared infants with and without low-grade IVH. @*Results@#Among the 109 extremely preterm infants, 25 had low-grade IVH and 84 had no IVH. There were no significant differences in the neurodevelopmental outcomes between the low-grade and no IVH groups. In multivariate analysis, low-grade IVH was associated with a smaller medullary volume (adjusted odds ratio, 0.575; 95% confidence interval, 0.346 to 0.957; P=0.034). @*Conclusion@#We found no significant differences in the neurodevelopmental outcomes of extremely preterm infants at a corrected age of 18 to 24 months between those with low-grade IVH and those without IVH. Low-grade IVH was associated with a smaller medullary volume.

ABSTRACT

To investigate the therapeutic effect and mechanism of Qingwen Baiduyin on acute lung injury (ALI) in mice induced by lipopolysaccharide (LPS). MethodA total of 144 C57BL/6 mice were randomly divided into the following groups: a normal group, a model group (LPS, 5 mg·kg-1), a dexamethasone group (5 mg·kg-1), and low-, medium-, and high-dose Qingwen Baiduyin groups (14.105, 28.21, 56.42 g·kg-1). The mice were treated once daily for 5 days. One hour after the final administration, the ALI model was established by intratracheal instillation of LPS, and samples were collected at 6 h and 24 h after modeling. The arterial blood gas index of mice was analyzed. The total protein content, total cell count, Evans blue dye (EBD) content, and lung tissue wet-to-dry weight ratio (W/D) of bronchoalveolar lavage fluid (BALF) were measured. Hematoxylin-eosin (HE) staining was performed to assess the pathological changes in mouse lung tissue. Western blot was used to detect the expression levels of key proteins in the Janus kinase 1/signal transducer and activator of transcription 1/interferon regulatory factor 1 (JAK1/STAT1/IRF1) signaling pathway in lung tissue. ResultCompared with the normal group, the model group showed reduced arterial oxygen pressure (pO2), oxygen saturation (SO2), and lung tissue W/D (P<0.05, P<0.01), increased carbon dioxide pressure (pCO2), total protein content, total cell count, EBD content, interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), chemokine CXC ligand 1 (CXCL1), chemokine CXC ligand 2 (CXCL2), chemokine CXC ligand 9 (CXCL9), and chemokine CXC ligand 10 (CXCL10) content (P<0.05, P<0.01), thickening of the alveolar walls, fusion of alveolar cavities, and infiltration of inflammatory cells in lung tissue, increased proportion of M1 macrophage polarization and lung cell apoptosis (P<0.05), and increased protein expression levels of JAK1, phosphorylated JAK1 (p-JAK1), inducible nitric oxide synthase (iNOS), STAT1, phosphorylated STAT1 (p-STAT1), IRF1, gasdermin D (GSDMD), and mixed lineage kinase domain-like protein (MLKL) (P<0.05, P<0.01). Compared with the model group, Qingwen Baiduyin significantly increased pO2, SO2, and lung tissue W/D (P<0.05, P<0.01), improved the pathological changes in lung tissue, and reduced pCO2, total protein content, total cell count, EBD content, IFN-γ, TNF-α, IL-1β, CXCL1, CXCL2, CXCL9, and CXCL10 content, proportion of M1 macrophage polarization, and protein expression levels of JAK1, p-JAK1, iNOS, STAT1, p-STAT1, IRF1, GSDMD, and MLKL (P<0.05, P<0.01). ConclusionQingwen Baiduyin can improve the lung inflammatory response and reduce lung cell apoptosis in mice with ALI by inhibiting the JAK1/STAT1/IRF1 signaling pathway, thereby exerting a lung-protective effect.

ABSTRACT

AIM: To investigate the difference, correlation, and consistency of corneal thickness and the thinnest point position detected by Pentacam HR corneal topography map and RTVue optical coherence tomography(OCT)in patients with keratoconus.METHODS: Cross-sectional comparative study. The corneal curvature map, corneal thickness map, thinnest point position, and thinnest point thickness were detected by Pentacam HR and RTVue OCT. Paired sample t-test was used for data consistent with normal distribution, and paired sample rank sum test was used for data inconsistent with normal distribution. Spearman correlation analysis and Bland-Altman analysis were used for the correlation and consistency of the two measurement methods.RESULTS: A total of 63 patients(105 eyes)with keratoconus were included in this study, including 49 males(77.8%)and 14 females(22.2%), aged 22.24±6.19 years; among them, relevant data of Pentacam HR topographic map: Km was 47.85±4.73D and Kmax was 55.43±8.72D. In measuring central corneal thickness and the thinnest point thickness of keratoconus, the Pentacam HR was 4.70μm and 19.46μm thicker than the mean value measured by RTVue OCT(P&#x003C;0.05). There was no significant difference between the horizontal and vertical coordinates of the thinnest points measured by the two devices(P&#x003E;0.05). The central corneal thickness and the thinnest point thickness measured by the two devices were highly correlated, the horizontal coordinate of the thinnest point was moderately correlated, and the vertical coordinate of the thinnest point was weakly correlated. Bland-Altman analysis showed that the central corneal thickness, the thinnest point thickness, the horizontal coordinate of the thinnest point, and the vertical coordinate of the thinnest point were 95.2%(100/105)and 93.3%(98/105), 95.2%(100/105), 95.2%(100/105)respectively, which were within the 95% consistency limit, while the consistency ranges were -36.00~+26.62μm, -42.27~+3.36μm, -0.80~+0.84mm, and -1.95~+1.06mm, respectively.CONCLUSION: In keratoconus, the central corneal thickness and the thinnest point thickness measured by Pentacam HR were higher than those measured by RTVue OCT. It is not recommended that the central corneal thickness and the thinnest point thickness measured by the two instruments be interchangeable in clinical use because of the wide range of consistency between the two instruments' results. The position of the thinnest corneal point measured by the two instruments is similar and consistent, so it could be considered to replace the measured values of the two instruments in clinical use.

ABSTRACT

Background and Objectives@#Nonpharmacologic interventions (NPIs), such as social distancing and preventive measures, were administered during the coronavirus disease (COVID-19) pandemic, which may influence the incidence of upper respiratory diseases (URDs). The present study compared the incidence of URDs during the COVID-19 pandemic and during the years prior to COVID-19, and investigated the effect of NPIs on URD in the nationwide general population.Subjects and Method This is an epidemiologic study based on the Korean National Health Insurance Database from March 2016 to February 2021. We compared the monthly incidence of URDs from March 2020 to February 2021 (12 months) with that of the past four years. A negative binomial regression model was used to evaluate the annual difference in the incidence of each URD and adjusting temperature, humidity, and the level of particulate matter 10 (PM10). @*Results@#The monthly incidence of ‘the five common URDs’ in 2020 was significantly lower than that in the past four years. The incidence of other chronic diseases, however, such as hypertension and diabetes mellitus, was comparable or higher in the past four years. Among the five common URDs, influenza virus infections decreased most dramatically, nearing 99%, from 296.4-377.1 per 100000 people during the period of 2016 to 2019 to 3.7 per 100000 people in 2020. @*Conclusion@#The present study shows that the incidence of ‘five common URDs’ significantly decreased during the era of COVID-19 in Korea. We believe that nationwide NPI might prevent the transmission of COVID-19 as well as other infectious sources associated with URDs.

ABSTRACT

Background@#This study was conducted to examine the effect of adverse childhood experiences on depressive symptoms in university students and to verify whether positive psychological resources act as a protective factor for depression. @*Methods@#Data from 1,317 young adults aged 18-29 years who took part in the university-based cross-sectional survey were analyzed. All participants completed self-report questionnaires that included demographic variables, the Adverse Childhood Experience (ACE) Scale, the Patient Health Questionnaire-9, and the Positive Resources Test. @*Results@#The incidence of depression was 33.3% and was higher in women than in men. Based on the 10 ACE categories, 32.7% of the students reported one or more adverse childhood experiences, and 14.4% reported two or more forms of adverse childhood experiences. Students with depressive symptoms were likely to report more traumatic experiences in childhood and fewer positive psychological resources than those without depressive symptoms. Hierarchical regression analysis indicated that positive psychological resources moderated the relationship between adverse childhood experiences and depression. @*Conclusion@#Based on these results, professionals should consider identifying adverse childhood experiences early and provide active mental health service support, including positive psychological and social resources for individuals who have adverse experiences during childhood.

ABSTRACT

The research on the processing mechanism of Chinese medicine is the key and core foundation to improve processing technologies of Chinese medicine, formulate the quality standards of Chinese medicinal pieces, enhance the clinical efficacy of Chinese medicine, enrich Chinese medicine processing theories, and promote the development of Chinese medicine processing. Many researc-hers have conducted in-depth exploration on the processing mechanism of Chinese medicine in the 20 years in the 21 st century. Significant progress has been made in the transformation of chemical components during the processing, the change of active components in the body, the law of toxicity attenuation in the processing of toxic Chinese medicine, the mechanism of efficacy enhancement and toxicity attenuation of processing with auxiliary materials, and the application of new biomedical technologies. At present, the processing mechanism of multiple Chinese medicines has been preliminarily clarified, which has greatly promoted the development of Chinese me-dicine processing. The development of the processing mechanism of Chinese medicine reveals that the in vitro transformation of chemical components is combined with the in vivo absorption, transport, and metabolism, and the macroscopic biological effects of the organism are combined with the cells, molecules, targets, and pathways in the study of the processing mechanism of Chinese medicine. More attention has been paid to exploring the processing mechanism from the overall level, and a modern systematic research system on the processing mechanism of Chinese medicine has been initially formed. To further promote the scientific development of Chinese me-dicine processing, the present study proposed that the research on the processing mechanism of Chinese medicine should take Chinese medicine properties into account, focus on the influence of disease condition on the mode of action and effect strength of the drugs, comply with the characteristics of clinical compound compatibility of Chinese medicine, use the holistic view research strategies of systems bio-logy, and deeply explore the processing mechanism of Chinese medicine from traditional Chinese medicine theories and the characteristics of clinical medication of Chinese medicine.

ABSTRACT

Objectives@#Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study investigated the impact of maternal ACEs on PTSD in the offspring. @*Methods@#A total of 156 mothers with children aged 13–18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. @*Results@#Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). @*Conclusion@#Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

ABSTRACT

By preparing 15 batches of substance benchmarks of Taohong Siwu Decoction, the methodology of the characteristic spectrums of substance benchmarks was established. The paste-forming rate range, the contents and the transfer rate range of the index components, hydroxy safflower yellow A, ferulic acid and paeoniflorin, the characteristic peaks and the similarity range of the characteristic spectrums of Taohong Siwu Decoction were determined to define key quality attributes of substance benchmarks of Taohong Siwu Decoction.In the 15 batches of substance benchmarks of Taohong Siwu Decoction, the similarity of characteristic spectrums was higher than 0.9. Furthermore, based on summarization of the characteristic peak information, there were 13 characteristic peaks in the whole decoction. Baishao had three characteristic peaks, Honghua had seven characteristic peaks, and Chuanxiong and Danggui had three characteristic peaks. The paste-forming rate of the 15 batches of substance benchmarks was controlled at 33.11%-40.62%. The content of hydroxy safflower yellow A was 0.129%-0.203%, with the average transfer rate of 16.596%±0.669%.The content of ferulic acid was 0.043%-0.055%, with the average transfer rate of 20.489%±1.772%.The content of paeoniflorin was 0.676%-0.943%, with the average transfer rate of 29.112%±3.273%.The quality value transfer of substance benchmarks of classical prescription Taohong Siwu Decoction was analyzed by the combination of characteristic spectrums, paste-forming rate and the content of index components. The established substance benchmark quality evaluation method was stable and feasible, and could provide a basis for quality control and subsequent development of relevant preparations of Taohong Siwu Decoction.

Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. @*Results@#Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). @*Conclusion@#Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

ABSTRACT

Background@#To address the high suicide rate in Korea, determining the suicidality risk factors is a key concern in policymaking and prevention. This study aimed to describe the effects of traumatic childhood experiences on suicidality among young adults. @*Methods@#This study included 1,379 subjects from two universities in Jeju, Korea. All participants completed selfadministered questionnaires that included demographic variables, the Adverse Childhood Experiences (ACE) scale to evaluate traumatic childhood experiences, and a Korean version of the Suicide Module of the Mini International Neuropsychiatric Interview to evaluate suicidality. @*Results@#Of the subjects, 33.2% reported experiencing traumatic childhood experiences, and the prevalence of positive suicidality was 21.8%. Regression analyses indicated a significant association between traumatic childhood experiences and positive suicidality after controlling for multiple variables. Furthermore, subjects with positive suicidality were likely to report experiencing more traumatic childhood experiences (p<0.001). After categorizing the subjects into two groups according to ACE score, the positive ACE group showed a higher risk of suicidal ideation (p<0.001, adjusted odds ratio [AOR]=2.09) and suicidal attempt (p<0.001, AOR=4.15) than those negative ACE. @*Conclusion@#Intervention and practical strategies for college students with a history of traumatic childhood experiences must be considered for suicide prevention.

ABSTRACT

Objectives@#Osteoporosis and fracture are known complications of systemic lupus erythematosus (SLE). We assessed the prevalence and risk factors for osteoporosis in patients with SLE. @*Methods@#A total of 155 female SLE patients were recruited retrospectively in 5 university hospitals. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry, and the fracture risk assessment tool (FRAX) for high-risk osteoporotic fractures was calculated with and without BMD. @*Results@#The mean age was 53.7 ± 6.8 years, and osteoporotic fractures were detected in 19/127 (15.0%) patients. The proportion of patients having a high-risk for osteoporotic fractures in the FRAX with and without BMD, and osteoporosis by the World Health Organization (WHO) criteria were 25 (16.1%), 24 (15.5%), and 51 (32.9%), respectively, and 48.0–68.6% of them were receiving treatment. On multivariate logistic analysis, nephritis (odds ratio [OR] 11.35) and cumulative dose of glucocorticoid (OR 1.1) were associated with high-risk by the FRAX with BMD, and low complement levels (OR 4.38), erythrocyte sedimentation rate (ESR) (OR 1.04), and cumulative dose of glucocorticoid (OR 1.05) were associated with osteoporosis by the WHO criteria in patients with SLE. @*Conclusions@#Among Korean female patients with SLE, the proportion of patients having a high-risk of osteoporotic fractures by the FRAX tool was 15.5%–16.1% and the proportion of patients having osteoporosis by the WHO criteria was 32.9%. In SLE, nephritis, low level of complement, ESR, and cumulative dose of glucocorticoids may contribute to fracture risk.

ABSTRACT

Background@#Abnormal chest radiographs are frequently encountered in patients with scrub typhus. This study aimed to investigate whether chest radiography on admission is significant as a predictive factor for acute kidney injury (AKI) in patients with scrub typhus. @*Methods@#From 2010 to 2016, 467 patients were diagnosed with scrub typhus in our hospital. We divided the patients into two groups: normal chest radiograph (NCR) and abnormal chest radiograph (AbNCR), based on chest radiography findings. The incidence, clinical characteristics, and severity of AKI were compared between AKI and non- AKI groups according to the RIFLE classification. @*Results@#Of the 467 patients, 96 (20.6%) constituted the AbNCR group. Compared with NCR patients, AbNCR patients were older (71 ± 11 vs. 62 ± 13 years, P < 0.001) and had higher total leukocyte counts (9.43 × 103/mL vs. 6.98 × 103/mL, P < 0.001). The AbNCR group had significantly longer duration of hospital stay (8.9 ± 5.5 vs. 6.3 ± 2.8 days, P < 0.001) and higher incidence of AKI (46.9% vs. 15.1%, P < 0.001). The common abnormal chest radiographic findings were pulmonary abnormalities, such as pulmonary congestion and pleural effusion. The overall AKI incidence was 21.6%, of which 12.4%, 7.9%, and 1.3% cases were classified as risk, injury, and failure, respectively. In a multivariable logistic regression analysis for association with AKI, old age, presence of chronic kidney disease or hypertension, leukocytosis, hypoalbuminemia, and chest radiographic abnormalities on admission were significant predictors of AKI. @*Conclusion@#Chest radiographic abnormalities on admission were independently associated with AKI in patients with scrub typhus.
