RESUMEN

BACKGROUND: High-dose chemotherapy combined with autologous hematopoietic stem cell transplantation (HDT/AHSCT) is used to treat lymphoma. Although AHSCT has made considerable strides and become safer, HDT-AHSCT infection continues to be a leading cause of morbidity and mortality associated with transplantation. OBJECTIVE: To characterise pathogenic bacterial infections in HDT/AHSCT-treated lymphoma patients. The prevalence of pathogenic microorganisms and the timing of foci after transplantation, along with bloodstream infection (BSI) risk factors, can help determine the need for empirical antibiotics after AHSCT. METHODS: We retrospectively analyzed 133 lymphoma patients treated by HDT/AHSCT from April 2017 to October 2021 at Peking University International Hospital, Beijing, China. We analyzed their clinical characteristics, microbiological distribution characteristics, and BSI risk factors in detail. RESULTS: In order, intestinal infection (56 cases), BSI (17 cases), pulmonary (12 cases), upper respiratory tract (5 cases), and perianal (4 cases) were the most common locations of infection after HDT/AHSCT. The infection sites yielded 92 putative pathogenic pathogens, with bacteria predominating (61.96%), fungi (28.26%), viruses (5.43%), and mycoplasma (4.35%). Gram-negative bacteria (GNB) strains outnumbered gram-positive bacteria (GPB) strains (73.68%). Two strains of Escherichia coli produced extended-spectrum ß-lactamase (ESBL) and one strain of carbapenem-resistant enterobacteriaceae (CRE). Methicillin-resistant Staphylococcus epidermidis (MRSE) had one strain. BSI was caused by Escherichia coli (82.35%), Intestinal mucositis (23.52%), and catheter-associated infections (11.76%). Age, CD34, pretreatment regimen, antibiotic regimen, and past chemotherapeutic agent lung damage were BSI risk variables in univariate analysis. CD34 and past chemotherapeutic drug lung damage were the primary causes of BSI after HDT/AHSCT for lymphoma. CONCLUSION: High-dose chemotherapy combined with autologous hematopoietic stem cell transplantation (HDT/AHSCT) is used to treat lymphoma. Although AHSCT has made considerable strides and become safer, HDT-AHSCT infection continues to be a leading cause of morbidity and mortality associated with transplantation.

RESUMEN

Introduction: The clinical significance of persistent positive in Hepatitis B Virus (HBV) DNA level in patients receiving antiviral therapy is not well known. We investigated factors associated with persistent viremia (PV) in patients with chronic hepatitis B (CHB) given 78-week entecavir. Methods: A total of 394 treatment-naïve CHB patients who had undergone liver biopsy at baseline and week 78 of treatment were analyzed in this prospective multicentre study. We identified patients with PV (above the lower limit of quantification, 20 IU/ml) after 78 weeks of entecavir therapy. Stepwise, forward, multivariate regression analyses of specified baseline parameters were apllied to identify factors associated with PV. Futhermore, we assessed the incidence of hepatocellular carcinoma (HCC) in all patients using models of the risk of HCC development. Results: Of the 394 patients, 90 (22.8%) still with PV after 78-week antiviral treatment. Factors associated significantly with PV (vs complete virological response, CVR) were HBV DNA level ≥8 log10 IU/mL (OR, 3.727; 95% CI, 1.851-7.505; P < 0.001), Anti-HBc level < 3 log10 IU/mL (OR, 2.384; 95% CI, 1.223-4.645; P=0.011), and HBeAg seropositivity (OR, 2.871; 95% CI, 1.563-5.272; P < 0.001). Patients with PV were less likely to have fibrosis progression and HCC development than those with the CVR. Of the 11 HBeAg-positive patients with HBV DNA level ≥8 log10 IU/mL and Anti-HBc level < 3 log10 IU/mL at baseline, 9 (81.8%) had persistent positivity in HBV DNA level and 0 had fibrosis progression at week 78 of treatment. Discussion: In conclusion, HBV DNA level ≥8 log10 IU/mL, Anti-HBc level < 3 log10 IU/mL and HBeAg seropositivity at baseline contribute to PV in patients with CHB receiving 78-week antiviral treatment. In addition, the rate of fibrosis progression and the risk of HCC development in patients with PV were kept low. The complete protocol for the clinical trial has been registered at clinicaltrials.gov (NCT01962155 and NCT03568578).

RESUMEN

Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is one of the broad host ranges and economically-important insect pests in tropical and subtropical areas. A wide range of hosts means they have strong adaptation ability to changes in dietary macronutrients (e.g., sucrose and protein). However, the effects of dietary conditions on the phenotypes and genotypes of B. dorsalis are still unclear. In this study, we aimed to investigate the effects of larval dietary sucrose on the life history traits and stress tolerance of B. dorsalis, and its defense response at the molecular level. The results showed that low-sucrose (LS) induced decreased body size, shortened developmental duration, and enhanced sensitivity to beta-cypermethrin. Otherwise, high-sucrose (HS) diet increased developmental duration, adult fecundity, and tolerance to malathion. Based on transcriptome data, 258 and 904 differentially expressed genes (DEGs) were identified in the NS (control) versus LS groups, and NS versus HS groups, respectively. These yielded DEGs were relevant to multiple specific metabolisms, hormone synthesis and signaling, and immune-related pathways. Our study will provide biological and molecular perspective to understand phenotypic adjustments to diets and the strong host adaptability in oriental fruit flies.

RESUMEN

BACKGROUND: The optimum prophylactic regimen against hepatitis B virus (HBV) recurrence after liver transplantation (LT) in HBV-infected patients is uncertain but of great clinical relevance. New evidence suggests that hepatitis B immunoglobulin (HBIG)-free approach would become a reasonable choice in the era of high-potency nucleos(t)ide analogues (HPNAs). We aimed to provide robust estimates for long-term survival and HBV recurrence in patients receiving different HBV-prophylaxis strategies after LT. METHODS: We did a systematic review and meta-analysis using both pseudo-individual patient data recovered from included studies (IPDMA) and conventional trial-level aggregate data meta-analysis (ADMA). Hazard ratios (HRs) were calculated using different Cox proportional hazard models accounting for inter-study heterogeneity. ADMA was conducted to pool outcomes at specific time points. RESULTS: A total of 16 studies involving 7897 patients and 41 studies involving 9435 were eligible for IPDMA and AMDA, respectively. Cumulative HBV recurrence rate and overall survival (OS) at 1, 3, 5 and 10 years post-LT were 0.3%, 0.9%, 1.2%, 1.7% and 95.6%, 89%, 86.4%, 86.4% in the HPNAs (i.e., entecavir and tenofovir) + HBIG combination group vs. 0.6%, 0.6%, 1.2%, 1.7% and 94.5%, 86.8%, 84.8%, 81.2% in the HPNAs monotherapy group (HR 1.20, 95% CI 0.56-2.60, p = 0.64; HR 1.09, 95% CI 0.70-1.69, p = 0.72), respectively. The results were compatible with AMDA. CONCLUSION: A similar HBV recurrence and overall survival were found in patients who used HPNAs (mainly entecavir) monotherapy as in those who received a combination of HPNAs and HBIG. These findings address concerns regarding the safety and effectiveness of HPNAs monotherapy.

RESUMEN

Background and Aims: Chronic hepatitis B (CHB) can cause liver fibrosis and lead to cirrhosis and cancer. As the effectiveness of antiviral therapy to reverse liver fibrosis is limited, We aimed to evaluate the effect of An-Luo-Hua-Xian pill (ALHX) on fibrosis regression in CHB patients treated with entecavir (ETV). Methods: Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX (ETV+ALHX) between October 1, 2013 and December 31, 2020. Demographic, laboratory, and liver histology data before and after 78 weeks of treatment were collected. The Ishak fibrosis score (F) was used and fibrosis regression required a decrease in F of ≥1 after treatment. Results: A total of 780 patients were enrolled, and 394 with a second liver biopsy after treatment were included in the per-protocol population, 132 in ETV group and 262 in ETV+ALHX group. After 78 weeks of treatment, the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients: 124/211 (58.8%) vs. 45/98 (45.9%), p=0.035. The percentage of patients with a decreased liver stiffness measurement (LSM) was higher in the ETV+ALHX group: 156/211 (73.9%) vs. 62/98 (63.%), p=0.056. Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression [odds ratio (OR)=1.94, p=0.018], and a family history of hepatocellular carcinoma was on the contrary. (OR=0.41, p=0.031). Conclusions: ETV combined with ALHX increased liver fibrosis regression in CHB patients.

RESUMEN

Peripheral nerve injury is one of the rare complications of adult-onset Still's disease (AOSD). We report a 20-year-old woman diagnosed with AOSD combined with severe sensory neuropathy. She presented with a sore throat, joint pain, rash, and lymphadenopathy. After receiving glucocorticoid therapy, her fever, rash, and inflammatory markers improved. Unexpectedly, 3 weeks after the onset, she experienced sudden paresthesia in her extremities, decreased muscle strength, and diminished tendon reflexes. The electrophysiological examination and peripheral nerve biopsy confirmed immune-mediated severe sensory neuropathy. For the first time, we report typical Wallerian degeneration in AOSD patients with sensory neuropathy by nerve biopsy. Compared with other common symptoms, the delayed aggravation of neurological symptoms may be an important characteristic of sensory neuropathy secondary to AOSD. We emphasize that intensive attention to neurological symptoms after general symptoms control, administration of adequate and appropriate prolonged immunosuppressive therapy, and long-term follow-up are essential for these patients.

RESUMEN

A total internal reflection system based on the weak value amplification principle is set up for the precise measurement of the thickness of an ultra-thin film. In this system, the film thickness is derived from the change of the double-peak pointer caused by the effective refractive index of the film, which is correlated to its thickness. The sensitivity and resolution of this system reached 2727.21 nm/RIU and 7.2×10-6 R I U, respectively, determined by using a sodium chloride solution with a refractive index of 1.331911. The growth process of TA/Fe(III) assembled films with thicknesses in the few nanometers range is monitored using the as-set-up system, and the experimental results are consistent with a theoretical calculation based on the Maxwell Garnett effective medium. Additionally, we theoretically calculated the detection limit for the thickness measurement of the film as 22 pm. We clearly provide a potential method for the precise measurement of the thickness of an ultra-thin film.

RESUMEN

BACKGROUND AND AIMS: Chronic hepatitis B is the main cause of liver cancer. However, the most neglected group has been treatment-naive chronic hepatitis B patients with normal alanine aminotransferase (ALT). People have tended to subjectively assume that the liver lesions of these patients are not serious and do not need antiviral treatment. However, the truth is not as optimistic as we thought. We aimed in this study to analyze the proportion of significant inflammation or fibrosis in aforementioned patients. METHODS: Medline, Embase, and Cochrane Library were searched up to January 10th 2020, to identify studies of these patients with liver biopsy. The double arcsine method was used with a random-effect model to combine the proportion of significant inflammation or fibrosis. Potential heterogeneity was explored by subgroup analysis and meta-regression. Outcome of interests included the proportion of significant inflammation or fibrosis and cirrhosis. The secondary outcome was to find the risk factors of significant histological changes. RESULTS: Nineteen eligible studies, with 2,771 participants, were included. The pooled proportion of significant inflammation or fibrosis was 35% [95% confidence interval (CI): 27 to 43] and 30% (95% CI: 25 to 36), respectively. The pooled proportion of cirrhosis was 3% [95% CI: 1 to 5, (12 studies; 1,755 participants)]. In subgroup analysis, old age [vs. young (<40 years-old), 44% vs. 26%, p=0.012] was significantly associated with higher fibrosis stage as well as cirrhosis [vs. young (<40 years-old), 4.8% vs. 1.8%, p<0.001]. CONCLUSIONS: About 1/3 of the treatment-naive chronic hepatitis B patients with normal ALT show significant histological changes, and some even have cirrhosis.

RESUMEN

BACKGROUND: Persistent liver inflammatory damage is the main risk factor for developing liver fibrosis, cirrhosis, and even hepatocellular carcinoma in chronic hepatitis B (CHB) patients. Thus, accurate prediction of the degree of liver inflammation is a high priority and a growing medical need. AIM: To build an effective and robust non-invasive model for predicting hepatitis B-related hepatic inflammation. METHODS: A total of 650 treatment-naïve CHB (402 HBeAg-positive and 248 HBeAg-negative) patients who underwent liver biopsy were enrolled in this study. Histological inflammation grading was assessed by the Ishak scoring system. Serum quantitative hepatitis B core antibody (qAnti-HBc) levels and 21 immune-related inflammatory factors were measured quantitatively using a chemiluminescent microparticle immunoassay. A backward feature elimination (BFE) algorithm utilizing random forest (RF) was used to select optional features and construct a combined model. The diagnostic abilities of the model or variables were evaluated based on the estimated area under the receiver operating characteristics curve (AUROC) and compared using the DeLong test. RESULTS: Four features were selected to predict moderate-to-severe inflammation in CHB patients using the RF-BFE method. These predictive features included qAnti-HBc, ALT, AST, and CXCL11. Spearman's correlation analysis indicated that serum qAnti-HBc, ALT, AST, and CXCL11 levels were positively correlated with the histology activity index (HAI) score. These selected features were incorporated into the model to establish a novel model named I-3A index. The AUROC [0.822; 95% confidence interval (CI): 0.790-0.851] of the I-3A index was significantly increased compared with qAnti-HBc alone (0.760, 95%CI: 0.724-0.792, P < 0.0001) in all CHB patients. The use of an I-3A index cutoff value of 0.41 produced a sensitivity of 69.17%, specificity of 81.44%, and accuracy of 73.8%. Additionally, the I-3A index showed significantly improved diagnostic performance for predicting moderate-to-severe inflammation in HBeAg-positive and HBeAg-negative CHB patients (0.829, 95%CI: 0.789-0.865 and 0.810, 95%CI: 0.755-0.857, respectively). CONCLUSION: The selected features of the I-3A index constructed using the RF-BFE algorithm can effectively predict moderate-to-severe liver inflammation in CHB patients.

RESUMEN

BACKGROUND: The management of discharge COVID-19 patients with recurrent positive SARS-CoV-2 RNA is challenging. However, there are fewer scientific dissertations about the risk of recurrent positive. The aim of this study was to explore the relationship between SARS-COV-2 RNA positive duration (SPD) and the risk of recurrent positive. METHODS: This case-control multi-center study enrolled participants from 8 Chinese hospital including 411 participants (recurrent positive 241). Using unadjusted and multivariate-adjusted logistic regression analyses, generalized additive model with a smooth curve fitting, we evaluated the associations between SPD and risk of recurrent positive. Besides, subgroup analyses were performed to explore the potential interactions. RESULTS: Among recurrent positive patients, there were 121 females (50.2%), median age was 50 years old [interquartile range (IQR): 38-63]. In non-adjusted model and adjusted model, SPD was associated with an increased risk of recurrent positive (fully-adjusted model: OR = 1.05, 95% CI: 1.02-1.08, P = 0.001); the curve fitting was not significant (P = 0.286). Comparing with SPD < 14 days, the risk of recurrent positive in SPD > 28 days was risen substantially (OR = 3.09, 95% CI: 1.44-6.63, P = 0.004). Interaction and stratified analyses showed greater effect estimates of SPD and risk of recurrent positive in the hypertension, low monocyte count and percentage patients (P for interaction = 0.008, 0.002, 0.036, respectively). CONCLUSION: SPD was associated with a higher risk of recurrent positive and especially SPD > 28 day had a two-fold increase in the relative risk of re-positive as compared with SPD < 14 day. What's more, the risk may be higher among those with hypertension and lower monocyte count or percentage.

RESUMEN

BACKGROUND: Hepatitis B core-related antigen (HBcrAg) is a promising disease-monitoring marker for chronic hepatitis B (CHB). We investigated correlations between HBcrAg with antiviral efficacy and virological and histological variables. METHODS: One hundred and forty-five CHB patients from the mainland of China between August 2013 and September 2016 who underwent liver biopsy received entecavir therapy and had paired liver biopsy at 78 weeks. We analyzed correlations between HBcrAg and virological and histological variables in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. We also explored the predictors of HBeAg loss after 78 weeks of antiviral therapy. Pearson correlation analysis and logistic forward stepwise regression were the main statistic methods. RESULTS: HBeAg-positive patients (n = 93) had higher baseline HBcrAg (median 7.4 vs. 5.3 log10 U/mL P < 0.001) and greater HBcrAg declines (median 1.6 vs. 0.9 log10 U/mL P = 0.007) than HBeAg-negative patients after 78 weeks of therapy. At baseline, HBcrAg correlated with hepatitis B virus (HBV) DNA in both HBeAg-positive (r = 0.641, P < 0.001) and -negative patients (r = 0.616, P < 0.001), with hepatitis B surface antigen (HBsAg) in HBeAg-positive patients (r = 0.495, P < 0.001), but not with anti-hepatitis B virus core antibody (anti-HBc). Weak correlations existed between HBcrAg, histology activity index (HAI; r = 0.232, P = 0.025), and Ishak fibrosis score (r = -0.292, P = 0.005) in HBeAg-positive patients. At 78 weeks, significant correlations existed only between HBcrAg and anti-HBc in HBeAg-positive (r = -0.263, P = 0.014) and HBeAg-negative patients (r = -0.291, P = 0.045). Decreased HBcrAg significantly correlated with reduced HBV DNA (r = 0.366, P = 0.001; r = 0.626, P < 0.001) and HBsAg (r = 0.526, P = 0.001; r = 0.289, P = 0.044) in HBeAg-positive and -negative patients, respectively, and with reduced HAI in HBeAg-positive patients (r = 0.329, P = 0.001). Patients with HBeAg loss (n = 29) showed a larger reduction in HBcrAg than those without (median 2.3 vs. 1.3 log10 U/mL, P = 0.001). In multivariate analysis, decreased HBcrAg was an independent predictor of HBeAg loss (P = 0.005). CONCLUSIONS: HBcrAg reflects viral replication and protein production. Decreased HBcrAg could predict HBeAg loss after antiviral therapy.

RESUMEN

BACKGROUND AND AIMS: A proportion of chronic hepatitis B virus (HBV) infection patients with normal alanine aminotransferase (ALT) should start antiviral therapy based on liver biopsy. We aim to evaluate the proportion of such patients, find noninvasive methods for identifying and then evaluate antiviral efficacy. METHODS: 253 chronic HBV infection patients with normal ALT were analyzed at baseline and 57 patients with histological indication for antiviral therapy (Histology activity index ≥5 and/or Ishak fibrosis score ≥3) and 140 patients with elevated ALT received entecavir therapy and were followed-up to 78 weeks with a second liver biopsy in this multi-center study. RESULTS: 127 (50.2%) of 253 patients with normal ALT fulfilled histological indication for antiviral therapy. Aspartate aminotransferase (P=0.049), anti-hepatitis B virus core antibody (P=0.001) and liver stiffness measurement (P=0.000) were independent variables for identifying histological indication for antiviral therapy. A noninvasive model (AAF) performed best among independent variables and other noninvasive models with area under the operating characteristic curve of 0.887. Antiviral efficacy showed that 38 (66.7%) of 57 patients had undetectable HBV DNA. 12 (41.4%) of 29 patients who were hepatitis B e antigen (HBeAg)-positive at baseline achieved HBeAg loss and 3 (10.3%) achieved HBeAg seroconversion. 25 (43.9%) of 57 patients achieved histological response. Moreover, 57 patients with normal ALT had a similar antiviral therapy efficacy with 140 patients with elevated ALT (P>0.1) except proportion of inflammation improvement and histological response (P=0.005, P=0.049). CONCLUSIONS: Half of chronic HBV patients with normal ALT should start antiviral therapy based on liver biopsy. A noninvasive model could be used as a reliable tool for antiviral therapy decision. Patients with normal or elevated ALT had a similar antiviral efficacy.

RESUMEN

Since December 2019, coronavirus disease (COVID-19) has rapidly swept the world. So far, more than 30 million people have been infected and nearly one million have died. Although the world is still in the stage of COVID-19 pandemic, the treatment of new cases and critically ill patients is the focus of the current work. However, COVID-19 patients lead to pulmonary fibrosis, such a serious threat to the prognosis of complications were also worthy of our attention. First of all, we proposed the possible mechanism of pulmonary fibrosis caused by SARS-CoV-2, based on the published data of COVID-19 ((i) Direct evidence: pulmonary fibrosis was found in autopsy and pulmonary puncture pathology. (ii) Indirect evidence: increased levels of fibrosis-related cytokines[transforming growth factor [TGF]- ß, tumor necrosis factor [TNF]- α, interleukin [IL]-6, etc] in peripheral blood of severe patients.) What is more, we summarized the role of three fibrosis-related signaling pathways (TGF- ß signal pathway, WNT signal pathway and YAP/TAZ signal pathway) in pulmonary fibrosis. Finally, we suggested the therapeutic value of two drugs (pirfenidone and nintedanib) for idiopathic pulmonary fibrosis in COVID-19-induced pulmonary fibrosis.

RESUMEN

BACKGROUND: Noninvasive measurements including transient elastography (TE) and two-dimensional shear wave elastography (SWE) have been used clinically instead of liver biopsy for regular assessment of liver fibrosis in chronic hepatitis B (CHB) patients. AIM: To investigate the diagnostic efficiency of SWE compared to TE by assessing independent influencing factors and performance for diagnosing significant fibrosis based on our cohort of treatment-naive CHB patients. METHODS: Fifty-four treatment-naive CHB patients who underwent liver biopsy to determine whether to initiate antiviral therapy were enrolled. SWE, TE, serum tests and liver biopsy were performed for all participants. The fibrosis-4 and aspartate aminotransferase to platelet ratio index scores were also calculated. Potential independent influencing factors on SWE and TE values were analyzed. Based on liver pathology results, the agreement and correlation were determined, and a comparison of the two methods was performed. RESULTS: There were 27 cases (50%) of mild fibrosis (F0-F2) and 27 (50%) cases of significant fibrosis (F3-F6); fibrosis was assessed with the Ishak scoring system. Multivariate linear regression analyses revealed that the fibrosis stage was the only factor that affected the SWE values (P < 0.001), whereas the total bilirubin level (P = 0.013) and fibrosis stage (P = 0.037) were independent factors that affected TE values. Orthogonal partial least squares discriminant analysis showed that the number of independent factors (VIP > 1) was higher for TE than SWE. Bland-Altman analysis showed satisfactory agreement between liver stiffness measurements (LSMs) of SWE and TE. Both SWE and TE could significantly discriminate significant fibrosis from mild fibrosis (P < 0.001). SWE exhibited a higher correlation with LSMs of liver fibrosis than TE (r = 0.65 and 0.50, P < 0.001). The diagnostic performance of SWE was better than that of TE for significant fibrosis (F > 2). The areas under the receiver operating characteristic curves of SWE and TE were 0.786 and 0.714, respectively. The optimal LSM cutoff values of SWE and TE were 9.05 kPa and 8.15 kPa, respectively. CONCLUSION: Compared to the TE value, the SWE value was less affected by other factors. SWE may be more sensitive and precise than TE in predicting significant fibrosis (> F2) in CHB patients.

RESUMEN

Background and AIM: To explore the efficacy treatment regimen in refractory PBC. METHODS: Triple treatment including ursodeoxycholic acid, prednisolone and immunosuppressant was prescribed to 47 refractory patients. Biochemistries, immune parameters, non-invasive liver fibrosis assessments were measured during follow-up. RESULTS: Triple therapy resulted in significant decrease in ALP, GGT, ALT, AST, TBIL, ALB, IgG, IgM, APRI, FIB-4 and S-INDEX. The biochemical cumulative normalization rates of ALP and other biochemical parameters were higher in long-term follow-up. Poor outcome was observed in patients with lower ALB, higher TBIL, PT, sp100 positivity and advanced liver pathology at baseline. Osteoporosis and bone fracture were observed in 15% patients. CONCLUSIONS: Triple therapy is associated with marked decrease and normalization of ALP and other parameters. ALB, TBIL, PT, sp100 and pathology were related with poor outcome. Osteoporosis should be closely monitored


ANTECEDENTES Y OBJETIVO: Explorar el régimen de tratamiento de eficacia en PBC refractario. MÉTODOS: Se prescribió un tratamiento triple que incluyó ácido ursodesoxicólico, prednisolona e inmunosupresor a 47 pacientes refractarios. Las bioquímicas, los parámetros inmunes, las evaluaciones no invasivas de fibrosis hepática se midieron durante el seguimiento. RESULTADOS: La triple terapia resultó en una disminución significativa de ALP, GGT, ALT, AST, TBIL, ALB, IgG, IgM, APRI, FIB-4 y S-INDEX. Las tasas de normalización bioquímica acumulada de ALP y otros parámetros bioquímicos fueron mayores en el seguimiento a largo plazo. Se observó un resultado deficiente en pacientes con ALB más bajo, TBIL más alto, PT, positivo de SP100 y enfermedad hepática avanzada al inicio del estudio. La osteoporosis y la fractura ósea se observaron en el 15% de los pacientes. CONCLUSIONES: La triple terapia se asocia con una marcada disminución y normalización de ALP y otros parámetros. ALB, TBIL, PT, SP100 y la enfermedad se relacionaron con un mal resultado. La osteoporosis debe estar bajo estrecha supervisión

RESUMEN

BACKGROUND AND AIM: We reviewed the medical records of primary biliary cholangitis patients who were diagnosed by liver biopsy and treated with the corresponding treatment. We evaluated the therapeutic effect and long-term prognostic indicators. METHODS: This observational cohort study enrolled 80 eligible patients diagnosed by liver biopsy between December 2013 and December 2018 in our department. UDCA monotherapy or UDCA added to prednisolone and immunosuppressant triple therapy was prescribed to patients. We analyzed and compared the demographic characteristics, biochemistry profiles, immune parameters, and noninvasive liver fibrosis assessments at baseline as well as the treatment efficacy, long-term outcomes and adverse effects at baseline and at each visit between the two groups. The indicators that could affect prognosis were assessed. RESULTS: Thirty-eight primary biliary cholangitis patients received UDCA monotherapy (group A), and another 42 patients received UDCA, prednisolone and immunosuppressant triple therapy (group B). After therapy, all patients showed significant improvements in liver biochemical parameters, immune indicators, and noninvasive fibrosis indicators (Fibrosis-4 (FIB-4), aspartate aminotransferase-to-platelet ratio index (APRI)), all P values<0.0001. The Mayo score also decreased significantly after treatment (P=0.022). Triple therapy was more effective, and there was a significant difference between the two groups. In addition, multivariate analysis showed that anti-gp210 antibody positivity; antimitochondrial antibody (AMA) negativity; high alkaline phosphatase (ALP), total bilirubin (TBIL) and globulin levels; and a severe degree of fibrosis at baseline were independent predictors of a poor prognosis. CONCLUSIONS: Triple therapy was a treatment option for UDCA-refractory PBC patients. Anti-gp210 antibody positivity; AMA negativity; high ALP, TBIL and globulin levels; and a severe degree of fibrosis at baseline were associated with a poor prognosis.

RESUMEN

Since December 2019, a viral pneumonia, named coronavirus disease 2019 (COVID-19), from Wuhan, China, has swept the world. Although the case fatality rate is not high, the number of people infected is large and there is still a large number of patients dying. With the collation and publication of more and more clinical data, a large number of data suggest that there are mild or severe cytokine storms in severe patients, which is an important cause of death. Therefore, treatment of the cytokine storm has become an important part of rescuing severe COVID-19 patients. Interleukin-6 (IL-6) plays an important role in cytokine release syndrome. If it is possible to block the signal transduction pathway of IL-6, it is expected to become a new method for the treatment of severe COVID-19 patients. Tocilizumab is an IL-6 receptor (IL-6R) blocker that can effectively block the IL-6 signal transduction pathway and thus is likely to become an effective drug for patients with severe COVID-19.
