ABSTRACT

O presente estudo foi realizado para determinar a prevalência geral de toxoplasmose em pavões de plumagem diferente e seu efeito nas enzimas de teste da função hepática dos hospedeiros. Um total de cem pavões de plumas diferenciais, como ombro preto (n = 52), azul (n = 28), branco (n = 10) e arlequim (n = 10) foram estudados no zoológico de Bahawalpur, no Paquistão, usando o Latex Agglutination Test (LAT) e ensaio imunossorvente ligado a enzima (ELISA). A prevalência geral por LAT e ELISA foi de 37% e 30%, respectivamente. Por LAT, observou-se uma prevalência não significativamente maior (P≥0,05) em gênero (37,77%) nos machos do que nas fêmeas (36,36%), enquanto os adultos apresentaram uma prevalência maior (37,97%) em relação aos jovens (33,33%). De acordo com o ELISA, uma prevalência significativamente (P <0,05) maior (35,55%) foi observada nos machos do que nas fêmeas (25,45%) e significativamente (P <0,05) maior prevalência (31,64%) foi registrada nos adultos do que nos jovens (23,80%). A análise do perfil bioquímico sérico mostrou que o nível de bilirrubina não teve elevação significativa nos hospedeiros infectados, em comparação aos não infectados, enquanto a concentração de albumina, alanina aminotransferase (ALT), aspartato aminotransferase (AST), fosfatase alcalina (ALP) foi significativamente (P <0,05) diferente nos hospedeiros infectados. Conclui-se que a toxoplasmose afeta as enzimas do teste da função hepática. Essa é uma pesquisa preliminar e requer mais pesquisas em todo o país, com populações e amostras maiores.(AU)

ABSTRACT

Resumen La bilirrubina es el producto final de la degradación del grupo hem. La bilirrubina no conjugada (BNC) se forma en las células retículoendoteliales, transportada al hígado, donde es conjugada a glucurónidos y secretada a los canalículos. La BNC se solubiliza en el suero por medio de su fuerte unión con la albúmina. La unión bilirrubina-albúmina es una función de las concentraciones de la albúmina y de la bilirrubina y de la afinidad de unión por la bilirrubina. La fracción de bilirrubina no unida o bilirrubina libre plasmática (Bf) se incrementa significativamente conforme el nivel de bilirrubina sérica total (BST) alcanza la capacidad de unión de la albúmina. La Bf es considerada un mejor indicador de neurotoxicidad que la BST, a causa de que solamente la bilirrubina libre puede cruzar la barrera hematoencefálica. En la práctica médica la bilirrubina es un marcador de disfunción hepática, colestasis o enfermedad hemolítica. Una variedad de factores limita la sensibilidad y la especificidad de la medición de la bilirrubina para detectar anormalidades: lipemia, hemólisis, exposición a la luz visible y el estado de ayuno. La hiperbilirrubinemia puede ser clasificada como prehepática, hepática y poshepática, y esto brinda un marco útil para identificar la causa subyacente. Además, hay bilirrubina conjugada y no conjugada. La hiperbilirrubinemia y la ictericia neonatales se presentan en casi todos los recién nacidos y puede ser benigna si su progresión a hiperbilirrubinemia es reconocida, monitoreada y prevenida o tratada en una manera oportuna.


Abstract Bilirubin is the end product of heme breakdown. Unconjugated bilirubin (UB) is formed in reticuloendothelial cells, transported to the liver where it is conjugated to glucuronides, and then secreted into the canaliculi. UB is solubilized in serum via very tight linkage to albumin. Bilirubin-albumin binding is a function of the concentration of bilirubin and albumin and the binding affinity for bilirubin. The fraction of unbound bilirubin or plasma free bilirubin (Bf) increases significantly as the total serum bilirubin (TSB) level approaches the binding capacity of albumin. Bf is thought to be better indicator of neurotoxicity than TSB, because only plasma free bilirubin can cross the blood-brain barrier. In medical practice bilirubin is a marker of liver dysfunction, cholestasis or hemolytic disease. A variety of factors limit both the sensitivity and the specificity of bilirubin measurement to detect the abnormalities: lipemia, hemolysis, exposure of visible light and fasting state. Hyperbilirubinemia can be categorised as prehepatic, hepatic or poshepatic, and this provides a useful framework for identifying the underlying cause. In addition, there are conjugated and unconjugated bilirubin. Neonatal hyperbilirubinemia and jaundice occur in almost all newborns and may be benign if its progression to extreme hyperbilirubinemia is recognized, monitored and prevented or managed in a timely manner.

ABSTRACT

ABSTRACT Objective The chia seed, an ancient pseudocereal, is rich in omega-3 fatty acids and polyphenols, and has been suggested to possess several health benefits. Although it has gained popularity among nutritionists, little is known about the systemic effects of chia and their interactions. Hence, hepatorenal indicators and plasma vitamin concentrations in chia-supplemented aluminum-exposed rats were investigated. Methods Wistar albino rats were either fed on a chia-rich- or standard-diet for 21 days and exposed to aluminum. Liver function tests (Alanine Aminotransferase, Aspartate Aminotransferase, Alkaline Phosphatase, Lactate Dehydrogenase), kidney function tests (Urea Nitrogen, Creatinine), and vitamin B12 and folic acid measurements were performed by using an automated analyzer. Results Aluminum exposure had no influence on renal function, as did chia supplementation. However, liver function was disturbed with the exposure to Aluminum and chia was of no use against it. Surprisingly, it was found that the animals fed on a chia-rich diet displayed higher concentrations of vitamin B12 which was not the case for folic acid. Conclusion It was deduced that a chia-rich diet has no effect on the renal function and is not able to reverse aluminum-induced hepatotoxicity; however, it may be of benefit against vitamin B12 insufficiency and thus, it may offer a novel treatment option which is particularly important in the vegan diet.


RESUMO Objetivo A semente de chia, um antigo pseudocereal, é rica em ácidos graxos ômega-3 e polifenóis e tem sido sugerida como tendo vários benefícios para a saúde. Embora tenha ganhado popularidade entre os nutricionistas, na verdade, pouco se sabe sobre os efeitos e interações sistêmicas da chia. Assim, investigamos os indicadores hepatorrenais e as concentrações plasmáticas de vitamina em ratos expostos ao alumínio suplementados com chia. Métodos Ratos albinos Wistar foram alimentados com dieta rica em chia ou padrão por 21 dias e expostos ao alumínio. Testes de função hepática (Alanina Aminotransferase, Aspartato Aminotransferase, Fosfatase Alcalina, Lactato Desidrogenase), testes de função renal (ácido úrico, Creatinina) e medições de vitamina B12 e ácido fólico realizada usando um analisador automático. Resultados A exposição ao alumínio não influenciou a função renal, assim como a suplementação de chia. No entanto, a função hepática foi perturbada com a exposição e a chia foi inútil contra ela. Surpreendentemente, descobrimos que os animais que se alimentavam de uma dieta rica em chia apresentavam concentrações mais elevadas de vitamina B12, o que não era o caso do ácido fólico. Conclusão Deduzimos que a dieta rica em chia não tem efeito sobre a função renal e não é capaz de reverter a hepatotoxicidade induzida pelo alumínio; no entanto, pode ser benéfico contra a insuficiência de vitamina B12 e, portanto, pode oferecer uma nova opção de tratamento que é particularmente importante na dieta vegana.

ABSTRACT

To explore the feasibility and clinical value of CT-based arterial enhancement fraction (AEF) for evaluating liver function in liver cirrhosis patients.
 Methods: Fifty-two patients with liver cirrhosis (Child-Pugh A, B, and C group included 13, 20, and 19 patients, respectively) and 17 patients without liver diseases as control were prospectively enrolled, respectively. All individuals underwent three-phase hepatic CT, and the color mapping of AEF were obtained in CT kinetics software, as well as the corresponding parameters, i.e., hepatic AEF (HAEF) and the ratio of HAEF to spleen AEF (H/S). The AEF parameters were compared among different groups, and the area under the receiver operating characteristic curve (AUROC) was calculated. The Spearman correlation analysis was performed between the AEF parameters and model for end-stage liver disease (MELD) score in liver cirrhosis patients.
 Results: The interobserver agreement of HAEF and H/S were perfect, and the intraclass correlation coefficient (ICC) were 0.918 (95% CI 0.871 to 0.949), 0.946 (95% CI 0.915 to 0.966), respectively. The HAEF and H/S among those groups were significant different (both P<0.001), and they elevated with the increase of Child-Pugh classification in liver cirrhosis patients (all P<0.05, except the H/S between Child-Pugh A and B). In all patients with liver cirrhosis, the AUROC of HAEF and H/S were 0.933 and 0.821 for Child-Pugh A, and were 0.925 and 0.915 for Child-Pugh C, respectively. The HAEF and H/S of patients with liver cirrhosis were significantly correlated with the MELD score (HAEF: r=0.752, P<0.001; H/S: r=0.676, P<0.001).
 Conclusion: CT-based AEF parameters including HAEF and H/S are closely associated with the severity and prognosis of patients with liver cirrhosis, which have the potential to estimate the liver function in liver cirrhosis patients quantitatively and effectively.

ABSTRACT

BACKGROUND/AIMS: Hepatitis B virus reactivation (HBVr) following chemotherapy (CMT) is well-known among hematologic malignancies, and screening recommendations are established. However, HBVr data in solid organ malignancy (SOM) patients are limited. This study aims to determine hepatitis B surface antigen (HBsAg) screening rates, HBV prevalence, and the rate of significant hepatitis caused by HBVr in SOM patients undergoing CMT.METHODS: Based on the Oncology unit’s registration database from 2009–2013, we retrospectively reviewed records of all SOM patients ≥18 years undergoing CMT at Songklanagarind Hospital who were followed until death or ≥6 months after CMT sessions. Exclusion criteria included patients without baseline liver function tests (LFTs) and who underwent CMT before the study period. We obtained and analyzed baseline clinical characteristics, HBsAg screening, and LFT data during follow-up.RESULTS: Of 3,231 cases in the database, 810 were eligible. The overall HBsAg screening rate in the 5-year period was 27.7%. Screening rates were low from 2009–2012 (7.8–21%) and increased in 2013 to 82.9%. The prevalence of HBV among screened patients was 7.1%. Of those, 75% underwent prophylactic antiviral therapy. During the 6-month follow-up period, there were three cases of significant hepatitis caused by HBVr (4.2% of all significant hepatitis cases); all were in the unscreened group.CONCLUSIONS: The prevalence of HBV in SOM patients undergoing CMT in our study was similar to the estimated prevalence in general Thai population, but the screening rate was quite low. Cases of HBVr causing significant hepatitis occurred in the unscreened group; therefore, HBV screening and treatment in SOM patients should be considered in HBV-endemic areas.

ABSTRACT

PURPOSE: Screening nonalcoholic fatty liver disease (NAFLD) by body mass index (BMI) as a single surrogate measure for obesity has limitations. We suggest considering body composition zones by drawing a body composition chart composed of body composition indices, including BMI and percent body fat (PBF), to visualize the risk of NAFLD in obese children and adolescents.METHODS: Thirty-eight boys diagnosed with NAFLD were selected retrospectively from patients who visited Konkuk University Medical Center from 2006 to 2015. They had gone through body composition analysis by bioelectrical impedance analysis (BIA), and biochemical analyses, including a liver function test (LFT) and lipid panel, were performed. Fat-free mass index (FFMI) and fat mass index (FMI) were calculated from body composition analysis and height. We plotted FFMI and FMI of patients on a body composition chart and classified the patients into zones A to D. In addition, we analyzed the correlations between LFT, lipid panel, and body composition indices.RESULTS: Thirty-three of 38 boys (86.8%) were located in zone C, corresponding to high BMI and PBF. Four boys (10.5%) were located in zone D, which correlates with sarcopenic obesity. One boy located in zone B was a muscular adolescent. Alanine aminotransferase level was positively correlated with PBF, FMI, and BMI z-score.CONCLUSION: Body composition zones on a body composition chart might be useful in risk assessment in obesity-related diseases such as NAFLD. Zones on a body composition chart could have practical applications, especially in sarcopenic obese children and adolescents.

ABSTRACT

Aripiprazole is an atypical antipsychotic that acts as a partial agonist of dopamine type 2 receptors as well as 5-HT1A receptors. It is used in the treatment of schizophrenia and in type 1 bipolar disorder for mania. Because aripiprazole is well tolerated with few side effects it is used off-label in other psychotic disorders. The prevalence of abnormal liver function tests with antipsychotic use is 32%, with clinically significant effects in 4% of cases. No cases of aripiprazole-induced liver injury have been published. We report a 28-year-old female who presented with non-affective first-episode psychosis and who was treated with aripiprazole. Initially she was medicated with 10 mg per day, with an increase to 20 mg per day on the 12th day of hospitalization. Nine days after she became icteric, with nausea and had a vomiting episode. Laboratory analysis revealed a very high level of alanine aminotransferase, and minor to moderately high levels of aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, and bilirubin. Aripiprazole was tapered and paliperidone was started with the improvement of clinical and laboratory findings.

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to describe the diagnostic yield of endoscopic ultrasound (EUS) in patients with isolated elevated levels of amylase and/or lipase. METHODS: A retrospective chart review was conducted at a large academic medical center from 2000 to 2016. Patients were selected based on having elevated amylase, lipase, or both, but without a diagnosis of pancreatitis or known pancreatobiliary disease. Patients were excluded if they had abnormal liver function tests or abnormal imaging of the pancreas. RESULTS: Of 299 EUS procedures performed, 38 met inclusion criteria. Symptoms were present in 31 patients, most frequently abdominal pain (87%). In 20 patients (53%), initial EUS most commonly found chronic pancreatitis (n=7; 18%), sludge (5; 13%), or new diagnosis of pancreas divisum (3; 8%). In the asymptomatic patients (7), 3 had a finding on EUS, most importantly sludge (2), stone (1), and pancreas divisum (1). No patients were diagnosed with a mass or pancreatic cyst. During the follow up period, 6 patients (22%) had cholecystectomy. CONCLUSIONS: In our study of patients with isolated elevations in amylase and/or lipase without acute pancreatitis who underwent EUS, approximately 50% had a pancreatobiliary finding, most commonly chronic pancreatitis or biliary sludge.

ABSTRACT

BACKGROUND: Biliary atresia is an extrahepatic progressive obliterate cholangiopathy that occurs in infants. Kasai procedure, a surgical method that can help re-establish bile flow from the liver into the intestine, is its first line treatment. Since infants with biliary atresia already have advanced hepatic dysfunction, all kinds of schemes should be considered to minimize further liver damage during surgery. The objective of this study was to compare the postoperative hepatic functions between the two commonly used inhalational anesthetics in infants undergoing the Kasai procedure (i.e., desflurane and sevoflurane). METHODS: This prospective, randomized, double-blind, single-center, and parallel group study included 40 children undergoing Kasai procedure. They were randomly allocated to Group S (sevoflurane) or Group D (desflurane). All the patients were anesthetized with designated anesthetic agent with the end-tidal concentration of about 0.8–1 minimum alveolar concentration. Postoperative hepatic functions were assessed by aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, prothrombin time, and total bilirubin. RESULTS: A total of 38 patients were selected for the study. In both groups, AST, ALT were increased in magnitude to the peak on postoperative day 0 and decreased to preoperative value at postoperative day 3. There were no significant differences between the groups in any laboratory results related to liver function. CONCLUSIONS: Sevoflurane and desflurane, inhalation anesthetics for maintaining anesthesia used in infants undergoing the Kasai procedure, did not show any difference in preserving postoperative hepatic function.

ABSTRACT

PURPOSE: Donor safety is the most important problem of living donor liver transplantation (LDLT). Although laparoscopic liver resection has gained popularity with increased surgical experience and the development of laparoscopes and specialized instruments, a totally laparoscopic living donor right hepatectomy (LDRH) technique has not been investigated for efficacy and feasibility. We describe the experiences and outcomes associated with LDRH in adult-to-adult LDLT in order to assess the safety of the totally laparoscopic technique in donors. METHODS: Between May 2016 and July 2017, we performed hepatectomies in 22 living donors using a totally laparoscopic approach. Among them, 20 donors underwent LDRH. We retrospectively reviewed the medical records to ascertain donor safety and the reproducibility of LDRH; intra-operative and post-operative results including complications were demonstrated after performing LDRH. RESULTS: The median donor age was 29 years old and the median body mass index was 22.6 kg/m2. The actual graft weight was 710 g and graft weight/body weight (GRWR) was 1.125. No donors required blood transfusion, conversion to open surgery, or reoperation. The postoperative mortality was nil and postoperative complications were identified in two donors. One had fluid collection in the supra-pubic incision site for graft retrieval and the second had a minor bile leakage from the cutting edge of the right hepatic duct stump. All the liver function tests returned to normal ranges within one month. CONCLUSION: LDRH is a feasible operation owing to low blood loss and few complications. However, LDRH can be initially attempted after attaining sufficient experience in laparoscopic hepatectomy and LDLT techniques.

ABSTRACT

BACKGROUND: Insulin therapy is the treatment of choice in type 2 diabetes mellitus (T2DM) patients who are not achieving glycemic goals despite triple oral hypoglycemic agent (OHA) combination therapy. However, there is still no additional treatment option for patients who cannot afford insulin therapy or who have various clinical limitations. The purpose of this study was to evaluate the clinical efficacy and safety of four OHA combination therapy in poorly controlled T2DM patients who could not afford insulin therapy. METHODS: Forty-seven T2DM patients were enrolled according to the following criteria: 1) glycosylated hemoglobin [HbA1c] > 8.5%, 2) ongoing treatment with 3 OHA combination therapy (metformin, sulfonylurea, dipeptidyl peptidase-4 inhibitor), or 3) combined limitations for applying insulin therapy. Patients were given the fourth OHA (pioglitazone) in addition to their previous treatment for 12 months. We evaluated changes in HbA1c, body weight, hypoglycemic events, and side effects. RESULTS: At study completion, mean HbA1c and fasting plasma glucose were significantly reduced from 9.6% to 8.04% and from 198.4 mg/dL to 161.5 mg/dL, respectively (P < 0.001). Mean body weight was significantly increased from 66.7 kg to 69.3 kg. Hypoglycemia and side effects were observed 18 times and only 3 cases showed abnormal liver function tests or edema. In addition, subjects with higher initial HbA1c levels and HOMA-beta showed an independent association with a greater reduction in HbA1c. CONCLUSION: The 4 OHA combination therapy is effective and safe when insulin is not feasible.

ABSTRACT

Hepatic duct diverticulum is a rare form of choledochal cyst that does not fit into the most widely used Todani classification system. Because of its rarity, it may be difficult for clinicians to diagnose and treat it. Here, we present a case of left hepatic diverticulum in a 57-year-old woman with epigastric pain. At presentation, there were mild elevations in the liver function tests. Computed tomography and magnetic resonance cholangiopancreatography showed diverticulum-like cystic lesion with sludge ball near the confluence portion of both intrahepatic bile duct, but the origin of the lesion could not be identified. The clinical impression was type II choledochal cyst. Surgical excision was planned due to recurrent abdominal pain. The operative findings revealed diverticulum arising from left hepatic duct. Histopathology confirmed the lesion to be diverticulum lined by biliary epithelium. The patient had no postoperative complication and no further symptoms since the operation.

ABSTRACT

Physicians of all specialties are required to assess abnormal results of liver function tests. Many patients with abnormal results in liver function tests do not have primary liver disease; most of the frequently requested tests are influenced by myriad non-hepatic factors. The most common tests are those for serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and bilirubin. Hepatocellular injury is indicated by abnormally elevated AST and ALT levels compared to the ALP level. Cholestatic injury is indicated by an abnormally elevated ALP level compared to AST and ALT levels. The majority of bilirubin circulates as unconjugated bilirubin, and an elevated conjugated bilirubin level is a marker of hepatocellular or cholestatic injury. Obtaining a detailed medical history, a clinical examination, and optimal interpretation of abnormal results of liver tests can enable the determination of the cause of liver diseases, facilitating their diagnosis and therapy.

ABSTRACT

Benign recurrent intrahepatic cholestasis (BRIC), a rare cause of cholestasis, is characterized by recurrent episodes of cholestasis without permanent liver damage. BRIC type 2 (BRIC2) is an autosomal recessive disorder caused by ABCB11 mutations. A 6-year-old girl had recurrent episodes of jaundice. At two months of age, jaundice and hepatosplenomegaly developed. Liver function tests showed cholestatic hepatitis. A liver biopsy revealed diffuse giant cell transformation, bile duct paucity, intracytoplasmic cholestasis, and periportal fibrosis. An ABCB11 gene study revealed novel compound heterozygous mutations, including c.2075+3A>G in IVS17 and p.R1221K. Liver function test results were normal at 12 months of age. At six years of age, steatorrhea, jaundice, and pruritus developed. Liver function tests improved following administration of phenylbutyrate and rifampicin. Her younger brother developed jaundice at two months of age and his genetic tests revealed the same mutations as his sister. This is the first report of BRIC2 confirmed by ABCB11 mutations in Korean siblings.

ABSTRACT

ABSTRACT Objective To study the relationship between exercise and malnourishment because recent evidence suggests that exercise can cause the beneficial adaptation of antioxidant systems, whereas malnourishment can cause harmful adaptation of these systems. Methods Thirty-two female Fischer rats were equally divided into Sedentary Control, Trained Control, Sedentary Malnourished and Trained Malnourished groups. The training protocol consisted of swimming for 30 minutes continuously for 5 days/week for 8 weeks. Results It was demonstrated that aspartate aminotransferase and alanine aminotransferase activities increased in malnourished rats, but physical training reversed these effects by lowering the raised levels. The glutathione level was diminished by malnourishment whereas physical training increased the levels of liver carbonyl protein and increased the levels of thiobarbituric acid reactive substances that were diminished by malnourishment. In addition, Trained Malnourished rats had a higher average body weight than Sedentary Malnourished ones (62.77g vs. 55.08g, respectively). Conclusion The data show that exercise was able to reverse or reduce damage caused by malnourishment, such as weight loss and liver dysfunction by a pathway independent of the participation of enzymes involved in antioxidant defense and that there is no interaction between exercise and malnutrition.


RESUMO Objetivo Estudar a relação entre exercício e desnutrição, pois evidências recentes sugerem que o exercício físico pode causar a adaptação benéfica de sistemas antioxidantes, enquanto a desnutrição pode causar adaptação prejudicial a esses sistemas. Métodos Trinta e duas ratas Fischer foram igualmente divididas nos grupos Controle Sedentário, Controle Treinado, Desnutrido Sedentário e Desnutrido Treinado. O protocolo de treinamento consistiu em nadar por 30 minutos continuamente por 5 dias/semana por 8 semanas. Resultados Demonstramos que as atividades de aspartato aminotransferase e alanina aminotransferase aumentaram em ratos desnutridos, mas o treinamento físico reverteu esses efeitos. O nível de glutationa foi diminuído pela desnutrição, enquanto o treinamento físico aumentou os níveis de proteína carbonilada do fígado e aumentou os níveis de substâncias reativas ao ácido tiobarbitúrico que foram diminuídas pela desnutrição. Além disso, os ratos desnutridos treinados tiveram um peso corporal médio maior que os desnutridos sedentários (62,77g vs 55,08g, respectivamente). Conclusão Os dados mostram que o exercício foi capaz de reverter ou reduzir os danos causados pela desnutrição, como perda de peso e a disfunção hepática por uma via independente da participação de enzimas envolvidas na defesa antioxidante e que não há interação entre exercício e desnutrição.

ABSTRACT

Objetivo: A hepatite B é uma doença infecciosa que atinge, aproximadamente, 2 bilhões de pessoas. Apresenta fase aguda que pode evoluir para a cura ou cronificar. O quadro da doença é avaliado por meio de enzimas hepáticas e marcadores sorológicos, que detectam anticorpos e antígenos produzidos pelo vírus. Esse trabalho teve como objetivo avaliar os diferentes marcadores da hepatite B através de exames laboratoriais de indivíduos infectados, correlacionando testes de função hepática com a evolução da doença. Métodos: Trata-se de estudo transversal retrospectivo realizado de 2010 a 2015, utilizando banco de dados de um laboratório de Caxias do Sul-RS. As variáveis estão apresentadas em média e desvio-padrão e foram comparadas utilizando o teste t Student para amostras dependentes e as variáveis entre os grupos pelo teste t Student para amostras pareadas. Resultados: Um total de noventa indivíduos foi incluído, com média de idade de 46,0±13,5 anos (51% homens). Quanto à evolução, 31% dos pacientes evoluíram para a cura e 69% para a crônica. Encontramos significância entre as enzimas ALT e GGT, no momento do diagnóstico, com as últimas dosadas pelo laboratório (p < 0,008 e p< 0,007, respectivamente). Entre os grupos, houve diferença entre ALT (inicial e final) do grupo cura (p = 0,012), o que não ocorreu no grupo que cronificou (p= 0,848). Conclusão: O estudo pôde revelar o comportamento das transaminases e GGT frente à contaminação pelo vírus da hepatite B, ficando evidente a importância do correto acompanhamento da hepatite B através desses exames laboratoriais para se conhecer a noção real do estado da patologia.

ABSTRACT

RESUMEN El virus de la hepatitis C es la principal infección trasmitida por los derivados de la sangre en los Estados Unidos, con 3.2 millones de individuos infectados. El alfa interferón inyectable ha sido históricamente la piedra angular en la terapia del virus de hepatitis C. Se revisaron las publicaciones los trabajos publicados en Medline, Scielo, PubMed, e Hinari, hasta comienzos del año 2016. Las principales palabras clave utilizadas fueron virus de la hepatitis C, hepatitis C crónica, Interferón, antivirales. Recientes adelantos han llevado a la disponibilidad de nuevos medicamentos antivirales, que con el desarrollo de nuevas terapias orales libres de interferón han convertido la terapia del virus de la hepatitis C más eficaz además de simplificar los regímenes del tratamiento. Aunque estos regímenes de tratamiento aún permanecen complicados, las nuevas recomendaciones y guías evolucionan rápidamente. El rápido desarrollo de nuevas terapias para la hepatitis C, han logrado métodos más eficaces con menos reacciones adversas que optimizan el tratamiento de estos enfermos (AU).


ABSTRACT The hepatitis C virus is the main infection transmitted by blood products in the United States, with 3.2 million of infected individuals. The injected alpha interferon has historically been the key stone in the therapy of the hepatitis C virus. The works published in Medline, Scielo, PubMed and Hinary until the beginning of 2016 were reviewed. The main used key words were HVC, cronic hepatitis C, interferon, antivirals. Recent advances have led to the availability on new antiviral drugs, developing new interferon-free oral therapies that make the therapy of hepatitis C virus more efficacious and make easier the treatment regimens. Although these treatment regimens are still complicated, the new recommendations and guidelines evolve quickly. The fast development of new therapies against hepatitis C has led to more efficacious methods with less adverse reactions, optimizing the treatment of these patients (AU).

ABSTRACT

BACKGROUND: Chronic inflammation can lower the seizure threshold and have influence on epileptogenesis. The components of red ginseng (RG) have anti-inflammatory effects. The abundance of peripherally derived immune cells in resected epileptic tissue suggests that the immune system is a potential target for anti-epileptogenic therapies. The present study used continuous electroencephalography (EEG) to evaluate the therapeutic efficacy of RG in intrahippocampal kainic acid (IHKA) animal model of temporal lobe epilepsy.METHODS: Prolonged status epilepticus (SE) was induced in 7-week-old C57BL/6J mice via stereotaxic injection of kainic acid (KA, 150 nL; 1 mg/mL) into the right CA3/dorsal hippocampus. The animals were implanted electrodes and monitored for spontaneous seizures. Following the IHKA injections, one group received treatments of RG (250 mg/kg/day) for 4 weeks (RG group, n=7) while another group received valproic acid (VPA, 30 mg/kg/day) (VPA group, n=7). Laboratory findings and pathological results were assessed at D29 and continuous (24 h/week) EEG monitoring was used to evaluate high-voltage sharp waves on D7, D14, D21, and D28.RESULTS: At D29, there were no differences between the groups in liver function test but RG group had higher blood urea nitrogen levels. Immunohistochemistry analyses revealed that RG reduced the infiltration of immune cells into the brain and EEG analyses showed that it had anticonvulsant effects.CONCLUSION: Repeated treatments with RG after IHKA-induced SE decreased immune cell infiltration into the brain and resulted in a marked decrease in electrographic seizures. RG had anticonvulsant effects that were similar to those of VPA without serious side effects.

ABSTRACT

BACKGROUND/AIMS: To evaluate the impact of isoniazid (INH) treatment for latent tuberculosis infection (LTBI) on the development of liver function test (LFT) abnormality and the persistence of tumor necrosis factor (TNF) inhibitors in rheumatoid arthritis (RA) patients. METHODS: We retrospectively enrolled patients with RA who were treated with TNF inhibitors at a university hospital between December 2000 and November 2011. After dividing the patients into two groups based on the occurrence of LFT abnormality during follow-up, we compared demographic and clinical features between the two groups. A multivariable logistic regression analysis was performed to identify the impact of INH treatment on LFT abnormality. The impact of INH treatment on the persistence of TNF inhibitors was also evaluated with the log-rank test and the Cox-proportional hazards model. RESULTS: A total of 312 RA patients including 96 patients (30.9%) who took INH for LTBI were included in this analysis. Thirty-nine patients (12.5%) experienced LFT abnormalities while using TNF inhibitors. The use of INH was associated with LFT abnormalities (odds ratio, 3.01; 95% confidence interval [CI], 1.39 to 6.48) after adjusting for covariates, including methotrexate use. However, the persistence of TNF inhibitors over 5 years did not differ between patients receiving or not receiving INH treatment (49.4 vs. 54.6%, p = 0.79). INH treatment was not a risk factor for discontinuation of TNF inhibitors (hazard ratio, 1.01; 95% CI, 0.66 to 1.57). CONCLUSION: INH treatment for LTBI in RA patients who started TNF inhibitors is associated with the occurrence of LFT abnormality; however, it does not lead to discontinuation of TNF inhibitors.

ABSTRACT

PURPOSE: To provide effective palliative care, it is important to predict not only patients' life expectancy but their discharge status at a time of inpatient admission to a hospice care facility. This study was aimed to identify meaningful life expectancy indicators that can be used to predict patients' discharge status on admission to the facility. METHODS: Among 568 patients who were admitted to the hospice ward of P hospital from April 1, 2016 through December 31, 2017, 377 terminal cancer patients were selected. This retrospective cohort study was performed by using performance status, symptoms and signs, socioeconomic status, laboratory findings on admission. RESULTS: Alive discharge was associated with a good performance status that was measured with the Karnofsky and Eastern Cooperative Oncology Group (ECOG) scales and the Global health and Mental status. Less anorexia, dyspnea, dysphagia and fatigue were also associated with symptoms and signs. Associated laboratory findings were close to normal Complete Blood Cell (CBC) count, Liver Function Test (LFT) and Blood Urea Nitrogen (BUN). CONCLUSION: Our findings suggest that Karnofsky Performance Status (KPS), ECOG, Global health, Mental status, anorexia, dyspnea, dysphagia, fatigue, CBC, LFT, BUN are meaningful indicators when predicting discharge status for inpatients. Further investigation is warranted.
