BMC Gastroenterol 2024; 24:21. [PMID: 38182992 PMCID: PMC10770890 DOI: 10.1186/s12876-023-03110-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 12/28/2023] [Indexed: 01/07/2024] Open
Abstract
BACKGROUND Liver disorders are important adverse effects associated with antifungal drug treatment. However, the accuracy of Clinical International Classification of Diseases (ICD)-10 codes in identifying liver disorders for register based research is not well-established. This study aimed to determine the positive predictive value (PPV) of the ICD-10 codes for identifying patients with toxic liver disease, hepatic failure, and jaundice among patients with systemic antifungal treatment. METHODS Data from the Swedish Prescribed Drug Register and the National Patient Register were utilized to identify adult patients who received systemic azole antifungal drugs and had a recorded diagnosis of toxic liver disease (K71.0, K71.1, K71.2, K71.6, K71.8, K71.9), hepatic failure (K72.0, K72.9), or jaundice (R17) between 2005 and 2016. The medical records of all included patients were reviewed. Prespecified criteria were used to re-evaluate and confirm each diagnosis, serving as the gold standard to calculate PPVs with 95% confidence intervals (95% CI) for each diagnostic group. RESULTS Among the 115 included patients, 26 were diagnosed with toxic liver disease, 58 with hepatic failure, and 31 with jaundice. Toxic liver disease was confirmed in 14 out of 26 patients, yielding a PPV of 53.8% (95% CI 33.4-73.4%). Hepatic failure was confirmed in 26 out of 38 patients, resulting in a PPV of 62.1% (95% CI 48.4-74.5%). The highest PPV was found in jaundice, with 30 confirmed diagnoses out of 31, yielding a PPV of 96.8% (95% CI 83.3-99.9%). CONCLUSION Among patients who received azole antifungal treatment and were subsequently diagnosed with a liver disorder, the PPV for the diagnosis of jaundice was high, while the PPVs for toxic liver disease and hepatic failure were lower.

Gaisenok O, Drapkina O. Gender differences in the detection of carotid atherosclerosis: DUPLEX registry cross-sectional study results. Monaldi Arch Chest Dis 2022; 92. [PMID: 35130677 DOI: 10.4081/monaldi.2022.2128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 01/22/2022] [Indexed: 11/23/2022] Open
Abstract
The aim of this study was to assess the features of detecting carotid atherosclerosis depending on gender, age, the presence of arterial hypertension, other major diseases and conditions according to The Duplex Registry Database. The registry sequentially included the results of duplex scanning of the carotid arteries (DSCA) of all patients who underwent it at the United Hospital with Outpatient Department in 2013 (n=2548). The incidence of carotid atherosclerosis (CAS) was higher in men than in women (58.6% (n=763) vs 45.5% (n=568), p<0.0000001). This was noted in all categories according to the gradation of stenosis, including in the category of the most severe lesion (>70%): 2.9% (n=32) vs 1.0% (n=13), p=0.003. The presence of CAD significantly increased the chances of detecting CAS in men (OR 4.47 vs 2.6, p<0.0000001). Signs more significant in their influence in women compared to men were the following: age (OR 5.3 [4.12; 6.71] p<0.0000001); arterial hypertension (OR 2.7 [2.12; 3.39] p<0.0000001) and cerebrovascular disease (OR 1.63 [1.13; 2.36] p=0.004). The OR of CAS detection for the "acute cerebrovascular accident" diagnosis in men and women differed 2 times (OR 1.2, p=0.4 vs 2.4, p=0.15). The "hypercholesterolemia" diagnosis when referred for DSCA did not show itself as a predictor of CAS detection in all study groups. Disorders of autonomic nervous system, hearing loss and screening examination showed a significant decrease in the probability of CAS detecting for the whole group (OR 0.14 [0.08;0.24] p<0.0000001; OR 0.16 [0.02;0.66] p=0.004 and OR 0.3 [0.25 0.37] p<0.0000001, respectively), so and separately for males and females. The present study revealed significant gender differences in the prevalence of carotid atherosclerosis and in the influence of various signs on an increase in the chances of its detection. The most significant signs were (OR men vs women): gender (1.3 vs 0.8), age (4.2 vs 5.3), arterial hypertension (1.8 vs 2.7), CAD (4.4 vs 2.6), cerebrovascular disease (1.26 vs 1.63).

Abstract
INTRODUCTION Idiosyncratic drug-induced liver injury (DILI) is an important cause of liver injury that is difficult to diagnose and identify in the electronic medical record (EMR). OBJECTIVE Our objective was to develop a computerized algorithm that can reliably identify DILI cases from the EMR. METHODS The EMR was searched for all encounters with an International Classification of Diseases, Tenth Revision (ICD-10) T code for drug toxicity and a K-71 code for toxic liver injury between 1 October 2015 and 30 September 2018. Clinically significant liver injury was defined using predetermined laboratory values. An expert opinion causality score (1-3 = probable DILI, 4/5 = non-DILI), Roussel Uclaf Causality Assessment Method (RUCAM) score, and severity score was assigned to each case. RESULTS Among the 1,211,787 encounters searched, 517 had both an ICD-10 T code and a K-71 code, with 257 patients meeting the laboratory criteria. After excluding 75 cases of acetaminophen hepatotoxicity, the final study sample included 182 cases of potential DILI, with antineoplastics and antibiotics being the most frequently implicated agents. Causality assessment identified probable DILI in 121 patients (66.5%), whereas 61 (33.5%) had an alternative cause of liver injury. Although age, sex, race, and suspect drugs were similar, the probable DILI cases were more likely to present with a hepatocellular injury profile and have more severe liver injury than the non-DILI cases (p < 0.05). CONCLUSION A computerized algorithm based on a combination of ICD-10 codes identified 182 potential DILI cases with 121 true positives, 61 false positives, and a positive predictive value of 66.5%. Future studies incorporating natural language processing may further improve the utility of this algorithm in identifying high-causality idiosyncratic DILI cases.

Abstract
Context: Camellia nitidissima Chi (Theaceae) is an evergreen shrub, the leaves of which are used in many medicinal applications.Objective: To characterize the chemical composition of a 10% aqueous ethanol extract of C. nitidissima leaves (CNE), and to explore the protective effect of the extract against acute liver injury (ALI) in rats.Materials and methods: Male Sprague-Dawley rats were divided into six groups (n = 10): control and negative (0.5% CMC-Na, 5 mL/kg/d), thiopronin (20 mg/kg/d) and CNE (40, 80 and 160 mg/kg/d). All groups were treated for seven consecutive days, and then, except for the control, carbon tetrachloride was administered intraperitoneally. The biochemical parameters, mRNAs, and proteins were analyzed using enzyme-linked immunoassays kits, quantitative polymerase chain reaction and western blot. Chemical components were identified using mass spectroscopy, and the phenol and flavonoid content determined by ultraviolet spectrophotometry.Results: Pre-treatment with CNE (160 mg/kg) attenuated the pathological changes in liver tissues and decreased alanine transaminase (62 and 60%), aspartate transaminase (49 and 53%) and malondialdehyde (35 and 42%) levels in serum and liver tissues. Moreover, CNE reduced the concentrations of reactive oxygen species (55%), tumour necrosis factor-α (26%), interleukin-1β (19%) and IL-6 (19%) and blocked the nuclear translocation of p65. Pre-treatment with CNE increased anti-heme oxygenase-1 (40%), superoxide dismutase (108%) and glutathione (97%) levels through upregulating nuclear factor erythroid-2-related factor 2. Twelve compounds were detected; the content of phenols and flavonoids was determined as 34.474 ± 1.026 and 15.228 ± 0.422 mg/g crude drug in CNE, respectively.Discussion and conclusions: These results suggested that CNE is a promising agent for functional food and hepatoprotective drug against ALI.

Abstract
PURPOSES Drug induced acute liver injury (ALI) is a frequent cause of liver failure. Case-based designs were empirically assessed and calibrated in the French National claims database (SNDS), aiming to identify the optimum design for drug safety alert generation associated with ALI. METHODS All cases of ALI were extracted from SNDS (2009-2014) using specific and sensitive definitions. Positive and negative drug controls were used to compare 196 self-controlled case series (SCCS), case-control (CC), and case-population (CP) design variants, using area under the receiver operating curve (AUC), mean square error (MSE) and coverage probability. Parameters that had major impacts on results were identified through logistic regression. RESULTS Using a specific ALI definition, AUCs ranged from 0.78 to 0.94, 0.64 to 0.92 and 0.48 to 0.85, for SCCS, CC and CP, respectively. MSE ranged from 0.12 to 0.40, 0.22 to 0.39 and 1.03 to 5.29, respectively. Variants adjusting for multiple drug use had higher coverage probabilities. Univariate regressions showed that high AUCs were achieved with SCCS using exposed time as the risk window. The top SCCS variant yielded an AUC = 0.93 and MSE = 0.22 and coverage = 86%, with 1/7 negative and 13/18 positive controls presenting significant estimates. CONCLUSIONS SCCS adjusting for multiple drugs and using exposed time as the risk window performed best in generating ALI-related drug safety alert and providing estimates of the magnitude of the risk. This approach may be useful for ad-hoc pharmacoepidemiology studies to support regulatory actions.

Abstract
Insufficient real-world data on acute liver injury (ALI) risk associated with oral anticoagulants (OACs) exist in patients with nonvalvular atrial fibrillation (NVAF). Using the French national healthcare databases, a propensity-weighted nationwide cohort study was performed in NVAF patients initiating OACs from 2011 to 2016, considering separately those (1) with no prior liver disease (PLD) as main population, (2) with PLD, (3) with a history of chronic alcoholism. A Cox proportional hazards model was used to estimate the hazard ratio with 95% confidence interval (HR [95% CI]) of serious ALI (hospitalised ALI or liver transplantation) during the first year of treatment, for each non-vitamin K antagonist (VKA) oral anticoagulant (NOAC: dabigatran, rivaroxaban, apixaban) versus VKA. In patients with no PLD (N = 434,015), only rivaroxaban new users were at increased risk of serious ALI compared to VKA initiation (adjusted HR: 1.41 [1.05–1.91]). In patients with chronic alcoholism history (N = 13,173), only those initiating dabigatran were at increased risk of serious ALI compared to VKA (2.88 [1.74–4.76]) but an ancillary outcome suggested that differential clinical follow-up between groups might partly explain this association. In conclusion, this study does not suggest an increase of the 1-year risk of ALI in NOAC versus VKA patients with AF.
