ABSTRACT
La hepatotoxicidad inducida por medicamentos es un diagnóstico de descarte. Típicamente, se presenta en pacientes que desarrollan cambios clínicos y bioquímicos compatibles con hepatitis, pero relacionados con el inicio reciente de agentes farmacológicos, y que se resuelven tras el retiro de la noxa. Su desarrollo se ha descrito con el uso de algunos antibióticos, antituberculosos, estatinas, herbolarios y antiinflamatorios no esteroideos; sin embargo, hay pocos reportes de casos con el uso de anticonceptivos orales, en los cuales el surgimiento de mecanismos idiosincráticos puede llevar a la presentación de características clínicas como ictericia y anormalidades en los exámenes de laboratorio, como la elevación de las transaminasas. Esto requiere de estudios extensos para descartar otras patologías que pueden presentarse de esta forma, lo que representa un reto clínico. En este artículo se muestra el reporte de un caso de una paciente con antecedente de uso crónico de anticonceptivos implantables y que, tras el ajuste de la terapia con el inicio de anticonceptivos orales, desarrolla un episodio de elevación marcada de transaminasas e ictericia.
Drug-induced liver injury is a rule-out diagnosis. Typically, it occurs in patients who develop clinical and biochemical changes compatible with hepatitis, but related to a history of recent onset of pharmacological agents, and resolves after withdrawal of the noxious substances. Its development has been described with the use of some antibiotics, antituberculosis agents, statins, herbal and nonsteroidal anti inflammatory drugs; however, there are few reports of cases with the use of oral contraceptives, in which the appearance of idiosyncratic mechanisms can lead to the presentation of clinical features such as jaundice and laboratory tests abnormalities, like transaminase elevation, requiring extensive studies to rule out other pathologies that may have this clinical presentation, wich represents a clinical challenge. We present a case report of a patient who had chronic use of implantable contraceptives and who, after adjustment of therapy with the start of oral contraceptives, developed an episode of marked elevation of transaminases and jaundice.
ABSTRACT
Tanto la lesión hepática inducida por drogas (DILI), así como la lesión hepática inducida por hierbas (HILI), son una preocupación creciente en la atención sanitaria contemporánea que plantea importantes desafíos clínicos debido a sus variadas etiologías, presentaciones clínicas y posibles resultados potencialmente mortales. Presentamos el caso de un paciente masculino de 38 años con antecedentes de cálculos renales que consultó por dolor lumbar y hematuria. Al ingreso presentó ictericia, hepatomegalia, dolor a la palpación en fosa ilíaca derecha y no tenía signos de hepatopatía crónica, con pruebas de función hepática anormales, que mostraron un patrón hepatocelular asociado con hiperbilirrubinemia. Se descartó obstrucción biliar, trombosis portal, hepatitis autoinmune y viral, con panel autoinmune negativo. El paciente refirió haber consumido un remedio herbario para los cálculos renales llamado "vino rompe cálculos (chancapiedra)", que se supone contiene Phyllanthus niruri, cinco días antes del inicio de los síntomas. Una biopsia hepática reveló hepatitis aguda con infiltrado inflamatorio mixto. Debido al empeoramiento de las pruebas de función hepática y la sospecha de DILI idiosincrásico, se inició un ensayo terapéutico con corticosteroides, que resultó en una mejoría clínica y del perfil hepático. La gravedad de este caso nos recuerda la necesidad de incrementar el seguimiento por parte de las autoridades reguladoras de medicamentos, implementar campañas educativas para los pacientes e informar a la comunidad sobre productos con alertas activas.
Both drug-induced liver injury (DILI) and herb-induced liver injury (HILI) are a growing concern in contemporary healthcare that poses significant clinical challenges due to their varied etiology, clinical presentations, and potential life-threatening outcomes. We present the case of a 38-year-old male patient with a history of kidney stones who consulted for low back pain and hematuria. On admission he presented with jaundice, hepatomegaly, pain on palpation in the right iliac fossa and no signs of chronic liver disease, with abnormal liver function tests, which showed a hepatocellular pattern associated with hyperbilirubinemia. Biliary obstruction, portal thrombosis, autoimmune and viral hepatitis were ruled out, with negative autoimmune panel. The patient reported consuming an herbal remedy for kidney stones called "stone-breaking wine (chancapiedra)", presumed to contain Phyllanthus niruri, five days before the onset of symptoms. A liver biopsy revealedacute hepatitis with mixed inflammatory infiltrate. Due to worsening liver function tests and suspicion of idiosyncratic DILI, a therapeutic trial with corticosteroids was initiated, which resulted in clinical and liver profile improvement. The severity of this case reminds us of the need to increase follow-up by drug regulatory authorities, implement educational campaigns for patients, and inform the community about products with active alerts.
ABSTRACT
ABSTRACT Objective: To report a pediatric case of drug-induced thrombotic microangiopathy caused by cocaine Case description: We report a nine-month-old patient who developed thrombotic microangiopathies after extreme cocaine intoxication, multiple organ dysfunction syndrome with hemodynamic dysfunction, anuric renal failure, liver failure, encephalopathy, and myocardial injury, corresponding phenotypically to thrombocytopenia-associated multiple organ failure. The patient received continuous venous hemofiltration and therapeutic plasma exchange, recovering satisfactorily. She was discharged after 30 days of hospitalization under the guidance of the childcare service, and was healthy after one year of follow-up. Toxicological samples confirmed high levels of cocaine and derivatives in blood, urine and hair. Comments: To our knowledge, this is the first reported pediatric case. There are particularities of cocaine intoxication pathophysiology that can trigger thrombotic microangiopathies because of vasoconstriction, direct endothelial injury, platelet activation, and increasing von Willebrand factor and fibrinogen levels. All of which results in a prothrombotic state, inflammatory dysregulation, and microvascular thrombi. The increasing use of cocaine, especially among young adults, puts children at high risk of toxicity, either by passive unintentional exposure, or abuse due to the increased availability in homes.
RESUMO Objetivo: Relatar um caso pediátrico de microangiopatia trombótica induzida por drogas causada por cocaína Descrição do caso: Relatamos uma paciente de nove meses de idade que desenvolveu microangiopatia trombótica após intoxicação extrema por cocaína, síndrome de disfunção de múltiplos órgãos com disfunção hemodinâmica, insuficiência renal anúrica, insuficiência hepática, encefalopatia e lesão miocárdica, correspondendo fenotipicamente à falência múltipla de órgãos associada à trombocitopenia. A paciente recebeu hemofiltração venosa contínua e plasmaférese terapêutica, recuperando-se satisfatoriamente. Recebeu alta após 30 dias de internação sob orientação do serviço de puericultura e estava saudável após um ano de seguimento. Amostras toxicológicas confirmaram altos níveis de cocaína e derivados no sangue, urina e cabelos. Comentários: Até onde sabemos, este é o primeiro caso pediátrico relatado. Existem particularidades da fisiopatologia da intoxicação por cocaína que podem desencadear a microangiopatia trombótica devido à vasoconstrição, lesão endotelial direta, ativação plaquetária e aumento do fator de von Willebrand e dos níveis de fibrinogênio. Tudo isso resulta em um estado pró-trombótico, desregulação inflamatória e trombos microvasculares. O uso crescente de cocaína, principalmente entre adultos jovens, coloca as crianças em alto risco de toxicidade, seja por exposição passiva não intencional ou abuso devido à maior disponibilidade nas residências.
ABSTRACT
Abstract Introduction Obstructive sleep apnea (OSA) is a severe form of sleep-disordered breathing (SDB) that is strongly correlated with comorbidities, in which epiglottic collapse (EC) and other contributing factors are involved. Objectives To evaluate the occurrence of EC in OSA patients through drug-induced sleep endoscopy (DISE) and to determine the factors contributing to EC. Methods A retrospective study of 37 adult patients using medical history. Patients were assessed for laryngopharyngeal reflux (LPR) and lingual tonsil hypertrophy (LTH) using reflux symptom index and reflux finding score (RFS); for OSA using polysomnography, and for airway collapse through DISE. An independent t-test was performed to evaluate risk factors, including the involvement of three other airway structures. Results Most EC patients exhibited trap door epiglottic collapse (TDEC) (56.8%) or pushed epiglottic collapse (PEC) (29.7%). Lingual tonsil hypertrophy, RFS, and respiratory effort-related arousal (RERA) were associated with epiglottic subtypes. Laryngopharyngeal reflux patients confirmed by RFS (t(25) = −1.32, p = 0.197) tended to suffer PEC; LTH was significantly associated (X2(1) = 2.5, p = 0.012) with PEC (odds ratio [OR] value = 44) in grades II and III LTH patients; 11 of 16 TDEC patients had grade I LTH. Pushed epiglottic collapse was more prevalent among multilevel airway obstruction patients. A single additional collapse site was found only in TDEC patients. Conclusion Laryngopharyngeal reflux causes repetitive acid stress toward lingual tonsils causing LTH, resulting in PEC with grade II or III LTH. Trap door epiglottic collapse requires one additional structural collapse, while at least two additional collapse sites were necessary to develop PEC. Respiratory effort-related arousal values may indicate EC.
ABSTRACT
Drug-induced liver injury is caused by the drug itself and/or its metabolites during drug use or occurs due to hypersensitivity or reduced tolerance to the drug in a particular body type. In the last three years of the diagnosis and treatment of coronavirus disease 2019 （COVID-19）， antiviral drugs have played a very important role， but there are many reports on liver injury caused by anti-COVID-19 drugs in China and globally， with unknown pathogenesis of liver injury caused by such drugs. This article reviews the research advances in the types of antiviral drugs for COVID-19 and their mechanism in inducing liver injury， in order to promote the rational use of antiviral drugs.
ABSTRACT
Idiosyncratic drug-induced liver injury (IDILI) has long posed a challenging and pivotal concern in pharmaceutical research. The complex composition of traditional Chinese medicine (TCM) has introduced a bottleneck in current research, hindering the elucidation of the component basis associated with IDILI in TCM. Using Epimedii Folium (EF) and Psoraleae Fructus (PF) as illustrative examples, this study endeavors to establish an in vitro evaluation model, providing a high-throughput and preliminary assessment method for screening components related to TCM-induced IDILI. A TNF-α-mediated HepG2 susceptible model was first established in this study, with the focus on the index components present in EF and PF. The release of lactate dehydrogenase (LDH) in the cell supernatant served as the detection index. A concentration-toxicity response curve was constructed, and the hepatotoxic components of EF and PF were identified utilizing the synergistic toxicity index. The LDH results unveiled the hepatotoxic effects of bavachin, backuchiol, isobavachin, neobavaisoflavone, psoralidin, isobavachalcone, icarisid I, and icarisid II on both normal and susceptible cells, categorizing these 8 components as both direct hepatotoxicity components and idiosyncratic hepatotoxicity components. Bavachin and neobavaisoflavone exhibited no hepatotoxicity on normal cells but demonstrated significant effects on susceptible cells, designating them as potential idiosyncratic susceptible hepatotoxicity components. The study further delineated that 10 EF components and 3 PF components were direct immune-promoting hepatotoxicity components. Additionally, 14 idiosyncratic immune-promoting hepatotoxicity components were identified, encompassing 10 EF components and 4 PF components, with neobavaisoflavone, bavachinin, and isobavachin being potential idiosyncratic susceptible immune-promoting hepatotoxicity components. Synergistic toxicity index results indicated that 13 idiosyncratic immune-promoting hepatotoxicity components (except anhydroicaritin) combined with bavachin demonstrated synergistic hepatotoxicity on susceptible cells. Notably, 3 idiosyncratic susceptible immune-promoting hepatotoxicity components combined with bavachin exhibited synergistic hepatotoxicity, with neobavaisoflavone displaying the highest synergistic toxicity index and bavachinin the lowest. In summary, this methodology successfully screens hepatotoxic and immune-promoting hepatotoxic components in EF and PF, distinguishing the types of components inducing hepatotoxicity, evaluating the hepatotoxicity degree of each component, and elucidating the synergistic relationships among them. Importantly, these findings align with the characteristics of IDILI. The method provides an effective model tool for the fundamental research of TCM-related IDILI components.
ABSTRACT
The incidence rate of drug-induced liver injury （DILI） is increasing year by year with unknown mechanisms， and the treatment methods for DILI mainly include drugs， liver support systems， and liver transplantation， all of which have certain limitations. Therefore， the search for safer and more effective treatment methods has become a research hotspot at present. Studies have shown that mesenchymal stem cells and their exosomes can alleviate liver injury by reducing liver inflammation， promoting hepatocyte proliferation and regeneration， inhibiting the apoptosis of hepatocytes， improving oxidative stress， and regulating immunity. This article briefly reviews the role of mesenchymal stem cells and their exosomes in the treatment of DILI， so as to provide a reference for further research.
ABSTRACT
Polygonum multiflorum （PM）， a commonly used Chinese herbal medicine in clinical practice， has been associated with frequent reports of liver injury in recent years， and the medication safety of PM has attracted more and more attention in China and globally. This article reviews the recent research advances in the signaling pathways and mechanisms of PM in causing drug-induced liver injury （DILI） and aims to provide new ideas for the proper and rational use of PM in clinical practice. The results show that PM is involved in the regulation of various signaling pathways， and it leads to the death of hepatocytes by destroying mitochondrial function， exacerbating bile acid accumulation， and inducing immune response， oxidative stress， and endoplasmic reticulum stress， thereby inducing the development and progression of DILI through multiple targets， pathways， and levels.
ABSTRACT
Pharmacotherapy is the primary treatment method for hyperthyroidism. Antithyroid drugs can induce liver injury， and the diagnosis of drug-induced liver injury is mostly exclusive based on medical history collection， clinical symptoms， serum biochemistry， radiological examination， and histology. According to the severity of liver injury， drug-induced liver injury can be classified into mild， moderate， severe， and fatal degrees. Drug withdrawal may not be necessary for patients with mild liver injury， but regular monitoring of liver function is required； in severe cases， patients may develop liver failure， which may lead to a mortality rate， and early identification， timely drug withdrawal， and reasonable pharmacotherapy can help to avoid fatal consequences. The treatment principles of liver injury induced by antithyroid drugs include promoting the recovery of liver injury， preventing the severe exacerbation and chronicity of liver injury， and reducing the risk of death. Standardized medication， timely monitoring， early identification， and early treatment are important measures for the prevention and treatment of liver injury induced by antithyroid drugs.
ABSTRACT
ObjectiveTo investigate the influencing factors for the clinical outcome of patients with drug-induced liver injury （DILI）， and to establish a nomogram prediction model for validation. MethodsA retrospective analysis was performed for the general information and laboratory data of 188 patients with DILI who were admitted to Heilongjiang Provincial Hospital Affiliated to Harbin Institute of Technology from January 2017 to December 2022， and according to their clinical outcome， they were divided into good outcome group with 146 patients and poor outcome group with 42 patients. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate Logistic regression analyses were used to investigate the independent influencing factors for the clinical outcome of DILI patients. R Studio 4.1.2 software was used to establish a nomogram model， and calibration curve， receiver operating characteristic （ROC） curve， and decision curve analysis （DCA） were used to perform internal validation. ResultsThe univariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI， platelet count， cholinesterase， albumin， prothrombin time activity， IgM， and IgG were associated with adverse outcomes in patients with DILI. The multivariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI （odds ratio ［OR］=0.072， 95% confidence interval ［CI］： 0.022 — 0.213， P<0.001）， clinical classification （OR=0.463， 95%CI： 0.213 — 0.926， P=0.039）， alanine aminotransferase （OR=0.999， 95%CI： 0.998 — 1.000， P=0.025）， prothrombin time activity （OR=0.973， 95%CI： 0.952 — 0.993， P=0.011）， and IgM （OR=1.456， 95%CI： 1.082 — 2.021， P=0.015） were independent influencing factors for clinical outcome in patients with DILI. The nomogram prediction model was established， and after validation， the calibration curve was close to the reference curve. The area under the ROC curve was 0.829， and the DCA curve showed that the model had good net clinical benefit. ConclusionThe nomogram prediction model established in this study has good clinical calibration， discriminative ability， and application value in evaluating the clinical outcome of patients with DILI.

Introduction: Antipsychotics are drugs that can produce transient elevations of hepatic enzymes. Clozapine is an atypical antipsychotic used in treatment-resistant schizophrenia and there is evidence that it can produce elevations of hepatic transaminases, expression of liver damage in a hepatocellular pattern. Methods: Case report and non-systematic review of the relevant literature. Case presentation: A 39-year-old woman with a diagnosis of paranoid schizophrenia attended the emergency department of a general hospital for nausea, vomiting and jaundice that appeared after the initiation of clozapine. There was no clinical improvement during hospitalization, and death occurred after 44 days. Literature review: Clozapine can increase the liver enzyme levels transiently and asymptomatically; however, there are clinical criteria that recommend the withdrawal of the antipsychotic. Conclusions: This is the third case reported in the literature of a fatal outcome of clozapine-induced hepatotoxicity.
ABSTRACT
Abstract Introduction Alterations in upper airway flow dynamics and sites of airway obstruction immediately after tonsillectomy and adenoidectomy (TA) have not been assessed. Identification of the changes in airway obstruction patterns after TA potentially improves the surgical management of children with obstructive sleep apnea (OSA). Objectives To evaluate the effect of TA on upper airway obstruction patterns detected with drug-induced sleep endoscopy (DISE). Methods The medical records of patients who underwent pre-TA DISE during the induction of anesthesia and post-TA DISE at the end of TA were reviewed. Data pertaining to polysomnography and DISE findings were analyzed. Results Twenty-seven patients (15 male and 12 females aged between 2 and 18 years old) were identified. All patients had obstruction at multiple sites of the upper airway. Prior to TA, airway obstruction was at the level of the velum in 27 patients, of the oropharynx/lateral walls in 27, of the tongue in 7, and of the epiglottis in 4. After TA, airway obstruction was at the level of the velum in 24 patients, of the oropharynx/lateral walls in 16, of the tongue in 6, and of the epiglottis in 4. The degree of obstruction at the levels of the velum and oropharynx/lateral walls after TA was significantly decreased. Conclusions Drug-induced sleep endoscopy performed prior to TA revealed that most of the sites of airway obstruction persisted after TA in OSA children with multiple sites of airway obstruction. Further studies in larger group of children with OSA are needed to establish the value of DISE findings in predicting residual OSA after TA, surgical planning, determining the need for post TA sleep study, and counseling caregivers.
ABSTRACT
Naproxen is a widely used nonsteroidal anti-inflammatory drug (NSAID) in pediatric population, used for mild-to-moderate pains, arthritis, and other immune-mediated disorders. It rarely causes clinically apparent liver injury in the adult population taking high doses of the drug over a prolonged period and is reported even rarer in pediatric population. We present a case of drug-induced liver injury (DILI) in a 13-year-old girl taking naproxen in therapeutic doses for juvenile rheumatoid arthritis. There was a complete recovery of liver function following discontinuation of naproxen therapy.
ABSTRACT
Acetaminophen is a drug widely used in the world and easily accessible due to its antipyretic, analgesics characteristics, among others (1); however, exposure to toxic doses causes organic damage and even death. We present the case of an 18-year-old female patient who ingested 40 grams of acetaminophen and developed severe liver dysfunction, being treated with N-acetylcysteine (NAC) antidotal therapy according to the simplified scheme: Scottish and Newcastle Anti-emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presenting improvement in the clinical course and decrease in liver profiles, coagulation disorder, INR and resolution of the condition.
El acetaminofén es un fármaco ampliamente usado en el mundo y de fácil acceso por sus características antipiréticas, analgésicas, entre otras (1); sin embargo la exposición a dosis tóxicas produce daños a nivel orgánico e incluso la muerte. Presentamos el caso de una paciente mujer de 18 años que ingirió 40 gramos de acetaminofén y desarrolló injuria hepática severa, siendo tratada con terapia antidotal de N-acetilcisteína (NAC) según el esquema simplificado: Scottish and Newcastle Anti-Emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presentando mejoría del curso clínico y disminución de los perfiles hepáticos, trastorno de coagulación, INR y resolución del cuadro.
ABSTRACT
Los medicamentos homeopáticos y fitoterapéuticos que contienen productos herbarios son cada vez más utilizados, sin embargo, se desconoce el potencial de efectos adversos por parte de los usuarios y personal sanitario. Se reporta el caso de una mujer de 34 años quien consulta por dolor abdominal y náuseas, con alteraciones al ingreso de función hepática con patrón hepatocelular, se descartaron múltiples etiologías y se consideró que pudiera ser lesión hepática medicamentosa secundaria al consumo de medicamentos desde hacía una semana para dismenorrea, y a fitoterapéuticos que consumía de forma crónica, los cuales se suspendieron. A los doce días de su egreso, reingresó por sintomatología similar; se documentó nuevamente perfil hepático con patrón hepatocelular. Al reinterrogatorio, la paciente comentó la ingesta crónica de Valeriana officinalis y Passiflora incarnata, que retomó al egreso hospitalario, por lo que luego de descartar diagnósticos diferenciales, se consideró que el cuadro era inducido por el consumo de dichos medicamentos. Durante la hospitalización se suspendió su consumo, con normalización del perfil hepático. Es importante que los consumidores estén informados sobre los riesgos potenciales de los productos herbarios, sus efectos por consumos prolongados y las implicaciones de la autoformulación.
Homeopathic and phytotherapeutic medicines containing herbal products are increasingly used, however the potential for adverse effects on users and healthcare personnel is unknown. We report the case of a 34-year-old woman who consulted for abdominal pain and nausea, accompanied by hepatocellular pattern on liver function tests. Multiple etiologies were ruled out and it was considered that it could be a drug-induced liver injury secondary to the consumption of medications she had been taking a week prior for dysmenorrhea, and phytotherapeutics that she had been taking for seve-ral years, which were all discontinued. Twelve days after her discharge, she was readmitted due to similar symptoms; a liver profile with a hepatocellular pattern was again documented. Upon further questioning, the patient mentioned a chronic intake of Valeriana officinalis and Passiflora incarnata, which she resumed upon discharge. After ruling out the differential diagnoses, it was concluded that the symptoms of the patient were induced by the consumption of these herbal products. During hos-pitalization, their consumption was suspended, with normalization of the liver profile. It is important that consumers are informed about the potential risks of herbal products, their effects from long-term use, and the implications of self-medication.
ABSTRACT
La enfermedad inflamatoria intestinal (EII) engloba dos entidades, la enfermedad de Crohn (EC) y la colitis ulcerativa (CU), las cuales son enfermedades inmunomediadas, crónicas y recurrentes que, aunque afectan al intestino, pueden ir acompañadas de manifestaciones extraintestinales de tipo hepatobiliar en el 5 % de los casos. Entre ellas, las más frecuentes son la enfermedad por hígado graso no alcohólico (EHGNA), la colelitiasis, la colangitis esclerosante primaria (CEP), la colangitis relacionada con IgG4, la hepatitis autoinmune (HAI), el síndrome de superposición HAI/CEP, así como la lesión hepática inducida por fármacos (DILI); y otras menos frecuentes como la colangitis biliar primaria (CBP), la trombosis de la vena porta, los abscesos hepáticos, la hepatitis granulomatosa, las hepatitis B y C, la reactivación de la hepatitis B por terapia inmunosupresora, y la amiloidosis. Estas manifestaciones hepatobiliares cursan con una fisiopatología similar o inclusive la misma de la EII, en la que participan el sistema inmune innato y adaptativo, alteración de la microbiota (disbiosis), permeabilidad intestinal, factores de riesgo genéticos (comunes para EII y manifestaciones hepatobiliares) y desencadenantes ambientales. La primera manifestación de un trastorno hepatobiliar es la alteración del perfil de función hepática, por lo que el abordaje diagnóstico se debe dirigir a evaluar y monitorizar las enzimas hepáticas y su asociación a algún patrón diferencial de alteración hepatocelular o colestásico, con el fin de tomar decisiones oportunas con respecto a la suspensión, indicación o modificación de algún medicamento, o cualquier otro abordaje que impida o retrase la evolución de la enfermedad hepatobiliar, y al mismo tiempo garantice el control de la EII, mejorando potencialmente el pronóstico de estos pacientes.
Inflammatory bowel disease (IBD) encompasses two entities, Crohn's disease (CD) and ulcerative colitis (UC), which are chronic, recurrent, immune-mediated inflammatory diseases that, although affect the gut, may be accompanied by extraintestinal hepatobiliary manifestations in 5% of the cases. Among them, the most frequent are non-alcoholic fatty liver disease (NAFLD), cholelithiasis, primary sclerosing cholangitis (PSC), IgG4-related cholangitis, autoimmune hepatitis (AIH), AIH/PSC overlap syndrome, as well as drug-induced liver injury (DILI); and other less frequent such as primary biliary cholangitis (PBC), portal vein thrombosis, liver abscesses, granulomatous hepatitis, hepatitis B and C, reactivation of hepatitis B due to different drugs, and amyloidosis. These hepatobiliary manifestations present with a pathophysiology similar or even the same as that of IBD, where several factors participate, including the innate and adaptive immune system, an interaction with the components of the microbiota, leaky gut, genetic risk factors (common for both IBD and hepatobiliary manifestations) and environmental triggers. The first manifestation of a hepatobiliary disorder is the alteration of the liver profile; therefore, the diagnostic approach should be aimed at evaluating and monitoring liver enzymes and their association with some differential pattern of hepatocellular or cholestatic changes, in order to make appropriate decisions regarding the suspension or modification of any medication, or any other approach that prevents or delays the evolution of hepatobiliary disease, and at the same time guarantees control of IBD, improving the prognosis of these patients.

Los riesgos teratogénicos ocasionados por la exposición intrauterina a fármacos antiepilépticos (FAE) son conocidos, por lo que su prescripción se mantiene bajo estricto control. Describir los efectos adversos fetales de la exposición a FAE durante la gestación, reportados en la literatura durante el período 2016-2022. Revisión sistematizada de estudios que reportaron los efectos adversos fetales inducidos por la exposición a FAE en mujeres embarazadas en tratamiento por diagnósticos neurológicos, principalmente de epilepsia. La búsqueda se realizó en PubMed, Cochrane, Web of Science, SCOPUS, Biblioteca Virtual en Salud, Lilacs y SciELO. Se identificaron 37 artículos distribuidos en 13 países de Asia, Europa, América del Norte y Oceanía. Se observaron resultados perinatales adversos, tanto físicos como cognitivos, en la mayoría de los estudios. Los fármacos identificados como los más utilizados en los últimos años fueron valproato, topiramato, carbamazepina, lamotrigina y levetiracetam. Los FAE tienen potencial teratogénico en distintos grados de riesgo, provocando anomalías congénitas o efectos adversos en múltiples sistemas del cuerpo humano, siendo los sistemas nervioso, circulatorio y osteomuscular los más afectados.
The teratogenic risks caused by intrauterine exposure to antiepileptic drugs (AED) are known, so their prescription is kept under strict control. To describe the fetal adverse effects AED exposure during gestation, reported in the literature during the period 2016-2022. Systematized review of studies that reported fetal adverse effects induced for the exposure to AED in pregnant women in treatment for neurological diagnoses, mainly epilepsy. The search was carried out in PubMed, Cochrane, Web of Science, SCOPUS, Virtual Health Library, Lilacs and SciELO. 37 articles distributed in thirteen countries in Asia, Europe, North America and Oceania were identified. Adverse perinatal outcomes, both physical and cognitive, were observed in most studies. The most common drugs identified were valproate, topiramate, carbamazepine, lamotrigine and levetiracetam. AED have teratogenic potential in different degrees of risk, causing congenital anomalies or adverse effects in multiple systems of the human body, being the nervous, circulatory and musculoskeletal systems the most affected.

AIM: To report 5 cases with drug-induced bilateral acute ciliochoroidal effusion(DBACE)and myopic shift, with or without ocular hypertension(OHT), summarize patients' clinical characteristics and recovery process of DBACE, and investigate the possible pathophysiological mechanism.METHODS:A retrospective observational case study conducted from June 2017 to February 2021. The included patients were subjected to a series of ocular examinations listed as follows: 1)best corrected visual acuity; 2)intraocular pressure(IOP); 3)slit-lamp microscopy; 4)fundus photography; 5)ultrasound biomicroscopy(UBM); 6)subjective optometry; 7)axial length and anterior chamber depth. All patients were followed up every 2d until the diopters were completely restored to the state before the disease onset.RESULTS:In total, 5 patients aged 10-45 years old, including 3 female and 2 male patients, were enrolled in this study. All patients were bilaterally involved(5/5), and had myopic shift(5/5), of whom 3 patients had OHT(3/5). With the increase of age, myopic shift decreased, while OHT increased. Based on OHT, the dynamic aggravation process of DBACE was subdivided into 2 stages, stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). With the deterioration of DBACE, when myopic shift approached or exceeded the minimum amplitude of accommodation(MAA), IOP gradually rose, and DBACE progressed from stage 1 to stage 2. With the recovery of DBACE after discontinuing the suspicious drugs, DBACE in stage 2 first returned to stage 1, and then returned to normal.CONCLUSION:Pathophysiological mechanism of DBACE was subdivided into 2 stages, including stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). The transition between the two stages depends on the imbalance between myopic shift and MAA.
ABSTRACT
@#A patient presents with jaundice three weeks into commencement of anti-tuberculosis therapy (ATT). Tuberculosis drug-induced liver injury (TB-DILI) is a main concern in patients commencing ATT. Studies have reported various risk factors associated with TB-DILI, urging vigilance in monitoring liver enzymes in these patients. We aim to review the causes of jaundice in a patient with transfusion dependent thalassaemia commenced on ATT and highlight the risk factors associated with TB-DILI.
