Abstract
BACKGROUND Insulin resistance and lipotoxicity are extremely interconnected but fundamental in setting the stage for the development of MASLD/MASH. AIM/METHODS A comprehensive literature search was performed and key themes were synthesised to provide insight into the underlying molecular mechanisms of insulin resistance and lipotoxicity in the liver, muscle, pancreas and adipose tissue and how organ cross-talk is fundamental to driving disease pathogenesis. RESULTS Classical thinking postulates that excess FFA load exceeds the storage capacity of adipose tissue, which is predicated upon both genetic and environmental factors. This results in insulin resistance and compensatory hyperinsulinaemia by pancreatic beta cells to overcome target organ insulin resistance. As adipocyte dysfunction worsens, not only are excess FFA delivered to other organs, including skeletal muscle, pancreas and liver but a pro-inflammatory milieu is established with increases in IL-6, TNF-α and changes in adipokine levels (increased leptin and decreased adiponectin). With increased intramuscular lipid accumulation, lipotoxic species decrease insulin signalling, reduce glucose uptake by downregulation of GLUT4 and decrease glycogen synthesis. With this additional reduced capacity, hyperglycaemia is further exacerbated and increased FFA are delivered to the liver. The liver has the largest capacity to oxidise fat and to adapt to these stressors and, therefore, has become the last line of defence for excess lipid storage and utilisation, the capacity of which may be impacted by genetic and environmental factors. However, when the liver can no longer keep up with increasing FFA delivery and DNL, lipotoxic species accumulate with ensuing mitochondrial dysfunction, increased ER stress, oxidant stress and inflammasome activation, all of which drive hepatocyte injury and apoptosis. The resulting wound healing response, marked by stellate cell activation, drives collagen accumulation, progressive fibrosis, and, ultimately, end organ failure and death. This vicious cycle and complex interplay between insulin resistance, hyperinsulinaemia, lipotoxicity and multi-directional cross-talk among different target organs are critical drivers of MASLD/MASH. CONCLUSIONS Targeting tissue-specific insulin resistance and hyperinsulinaemia while decreasing FFA load (lipotoxicity) through dietary and lifestyle changes remain the best upstream interventions.

Abstract
BACKGROUND Nonalcoholic steatohepatitis (NASH) is a progressive liver disease with no approved treatment. Resmetirom is an oral, liver-directed, thyroid hormone receptor beta-selective agonist in development for the treatment of NASH with liver fibrosis. METHODS We are conducting an ongoing phase 3 trial involving adults with biopsy-confirmed NASH and a fibrosis stage of F1B, F2, or F3 (stages range from F0 [no fibrosis] to F4 [cirrhosis]). Patients were randomly assigned in a 1:1:1 ratio to receive once-daily resmetirom at a dose of 80 mg or 100 mg or placebo. The two primary end points at week 52 were NASH resolution (including a reduction in the nonalcoholic fatty liver disease [NAFLD] activity score by ≥2 points; scores range from 0 to 8, with higher scores indicating more severe disease) with no worsening of fibrosis, and an improvement (reduction) in fibrosis by at least one stage with no worsening of the NAFLD activity score. RESULTS Overall, 966 patients formed the primary analysis population (322 in the 80-mg resmetirom group, 323 in the 100-mg resmetirom group, and 321 in the placebo group). NASH resolution with no worsening of fibrosis was achieved in 25.9% of the patients in the 80-mg resmetirom group and 29.9% of those in the 100-mg resmetirom group, as compared with 9.7% of those in the placebo group (P<0.001 for both comparisons with placebo). Fibrosis improvement by at least one stage with no worsening of the NAFLD activity score was achieved in 24.2% of the patients in the 80-mg resmetirom group and 25.9% of those in the 100-mg resmetirom group, as compared with 14.2% of those in the placebo group (P<0.001 for both comparisons with placebo). The change in low-density lipoprotein cholesterol levels from baseline to week 24 was -13.6% in the 80-mg resmetirom group and -16.3% in the 100-mg resmetirom group, as compared with 0.1% in the placebo group (P<0.001 for both comparisons with placebo). Diarrhea and nausea were more frequent with resmetirom than with placebo. The incidence of serious adverse events was similar across trial groups: 10.9% in the 80-mg resmetirom group, 12.7% in the 100-mg resmetirom group, and 11.5% in the placebo group. CONCLUSIONS Both the 80-mg dose and the 100-mg dose of resmetirom were superior to placebo with respect to NASH resolution and improvement in liver fibrosis by at least one stage.

Abstract
Tremendous effort has been put forth over the past 2 decades in understanding the pathophysiology of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH). Although multiple potential targets for drug development exist, there have been no approved therapies for NAFLD/NASH. Lipotoxicity, owing to increased delivery of fatty acids to the liver, and hepatic de novo lipogenesis are key drivers of disease pathogenesis. Moreover, genetics, environmental factors, and comorbid conditions converge to determine disease progression in individual patients. Given the complexity and heterogeneity of disease pathogenesis, numerous therapeutic targets have emerged and have been tested in clinical trials. Early trial failures have provided key lessons and foundational insights to move the field forward. Current ongoing phase 3 trials and emerging phase 2 trials are reasons for optimism, and 2 drugs, obeticholic acid and resmetirom, are being evaluated for accelerated approval by the US Food and Drug Administration this year. This article highlights key features of NASH pathophysiology and drug targets, the lessons learned from completed trials, and the current landscape of phase 2 and 3 clinical trials in NASH.

Abstract
Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of fatty liver disease, including non-alcoholic fatty liver (NAFL) and its more progressive form, non-alcoholic steatohepatitis (NASH). The prevalence of NAFLD/NASH along with type 2 diabetes and obesity is rising worldwide. In those who develop NASH, unlike those with bland steatosis (NAFL), lipotoxic lipids drive hepatocyte injury, inflammation and stellate cell activation leading to progressive accumulation of collagen or fibrosis, ultimately leading to cirrhosis and increased risk of hepatocellular carcinoma. Hypothyroidism is associated with NAFLD/NASH; specifically, intrahepatic hypothyroidism drives lipotoxicty in preclinical models. Agonists of thyroid hormone receptor (THR)-β, which is primarily found in the liver, can promote lipophagy, mitochondrial biogenesis and mitophagy, stimulating increased hepatic fatty acid β-oxidation, and thereby decreasing the burden of lipotoxic lipids, while promoting low-density lipoprotein (LDL) uptake and favourable effects on lipid profiles. A number of THR-β agonists are currently being investigated for NASH. This review focuses on resmetirom, an orally administered, once-daily, small-molecule, liver-directed, ß-selective THR agonist, as it is furthest along in development. Data from completed clincal studies outlined in this review demonstrate that resmetirom is effective in reducing hepatic fat content as measured by magnetic resonance imaging-derived proton density fat fraction, reduces liver enzymes, improves non-i nvasive markers of liver fibrogenesis and decreases liver stiffness, while eliciting a favourable cardiovascular profile with a reduction in serum lipids, including LDL cholesterol. Topline phase III biopsy data showed resolution of NASH and/or fibrosis improvement after 52 weeks of treatment, with more detailed peer-reviewed findings anticipated in order to certify these findings. Longer term clinical outcomes from both MAESTRO-NASH and MAESTRO-NASH OUTCOMES will be a pivotal juncture in the drug's road towards being approved as a NASH therapeutic.

Abstract
Background & Aims The prevalence and aetiology of liver fibrosis vary over time and impact racial/ethnic groups unevenly. This study measured time trends and identified factors associated with advanced liver fibrosis in the United States. Methods Standardised methods were used to analyse data on 47,422 participants (≥20 years old) in the National Health and Nutrition Examination Survey (1999-2018). Advanced liver fibrosis was defined as Fibrosis-4 ≥2.67 and/or Forns index ≥6.9 and elevated alanine aminotransferase. Results The estimated number of people with advanced liver fibrosis increased from 1.3 million (95% CI 0.8-1.9) to 3.5 million (95% CI 2.8-4.2), a nearly threefold increase. Prevalence was higher in non-Hispanic Black and Mexican American persons than in non-Hispanic White persons. In multivariable logistic regression analysis, cadmium was an independent risk factor in all racial/ethnic groups. Smoking and current excessive alcohol use were risk factors in most. Importantly, compared with non-Hispanic White persons, non-Hispanic Black persons had a distinctive set of risk factors that included poverty (odds ratio [OR] 2.09; 95% CI 1.44-3.03) and susceptibility to lead exposure (OR 3.25; 95% CI 1.95-5.43) but did not include diabetes (OR 0.88; 95% CI 0.61-1.27; p =0.52). Non-Hispanic Black persons were more likely to have high exposure to lead, cadmium, polychlorinated biphenyls, and poverty than non-Hispanic White persons. Conclusions The number of people with advanced liver fibrosis has increased, creating a need to expand the liver care workforce. The risk factors for advanced fibrosis vary by race/ethnicity. These differences provide useful information for designing screening programmes. Poverty and toxic exposures were associated with the high prevalence of advanced liver fibrosis in non-Hispanic Black persons and need to be addressed. Impact and Implications Because liver disease often produces few warning signs, simple and inexpensive screening tests that can be performed by non-specialists are needed to allow timely diagnosis and linkage to care. This study shows that non-Hispanic Black persons have a distinctive set of risk factors that need to be taken into account when designing liver disease screening programs. Exposure to exogenous toxins may be especially important risk factors for advanced liver fibrosis in non-Hispanic Black persons.

Abstract
While the interactions between HIV and various liver cell populations have been explored, the relevance of these interactions when patients are well-controlled on ART is less clear. Therefore, we focus this perspective on HIV-related alterations that may drive hepatic inflammation and fibrosis in aviremic patients, with a focus on Kupffer cells and Hepatic Stellate Cells. Persistent CD4+ T cell depletion in the gut resulting in increased gut permeability has been postulated to play a role in systemic immune activation in HIV patients. The liver, with its unique location, remains the gatekeeper between the gut and the systemic circulation. The resident liver macrophage, Kupffer cell, is responsible for clearing and responding to these products. We propose that changes in Kupffer cell biology, in the context of HIV infection, creates a mileu that drives hepatic inflammation and fibrosis in response to microbial translocation. Targeting these pathways may be helpful in improving liver-related outcomes in HIV patients.

Abstract
BACKGROUND Non-alcoholic steatohepatitis (NASH) is characterised by hepatic steatosis, inflammation, hepatocellular injury, and progressive liver fibrosis. Resmetirom (MGL-3196) is a liver-directed, orally active, selective thyroid hormone receptor-β agonist designed to improve NASH by increasing hepatic fat metabolism and reducing lipotoxicity. We aimed to assess the safety and efficacy of resmetirom in patients with NASH. METHODS MGL-3196-05 was a 36-week randomised, double-blind, placebo-controlled study at 25 centres in the USA. Adults with biopsy confirmed NASH (fibrosis stages 1-3) and hepatic fat fraction of at least 10% at baseline when assessed by MRI-proton density fat fraction (MRI-PDFF) were eligible. Patients were randomly assigned 2:1 by a computer-based system to receive resmetirom 80 mg or matching placebo, orally once a day. Serial hepatic fat measurements were obtained at weeks 12 and 36, and a second liver biopsy was obtained at week 36. The primary endpoint was relative change in MRI-PDFF assessed hepatic fat compared with placebo at week 12 in patients who had both a baseline and week 12 MRI-PDFF. This trial is registered with ClinicalTrials.gov, number NCT02912260. FINDINGS 348 patients were screened and 84 were randomly assigned to resmetirom and 41 to placebo at 18 sites in the USA. Resmetirom-treated patients (n=78) showed a relative reduction of hepatic fat compared with placebo (n=38) at week 12 (-32·9% resmetirom vs -10·4% placebo; least squares mean difference -22·5%, 95% CI -32·9 to -12·2; p<0·0001) and week 36 (-37·3% resmetirom [n=74] vs -8·5 placebo [n=34]; -28·8%, -42·0 to -15·7; p<0·0001). Adverse events were mostly mild or moderate and were balanced between groups, except for a higher incidence of transient mild diarrhoea and nausea with resmetirom. INTERPRETATION Resmetirom treatment resulted in significant reduction in hepatic fat after 12 weeks and 36 weeks of treatment in patients with NASH. Further studies of resmetirom will allow assessment of safety and effectiveness of resmetirom in a larger number of patients with NASH with the possibility of documenting associations between histological effects and changes in non-invasive markers and imaging.

Abstract
Healthcare reimbursement is shifting from fee-for-service to fee-for-value. Cirrhosis, which costs the U.S. healthcare system as much as heart failure, is a prime target for value-based care. This article describes models in which physician groups or health systems are paid for improving quality and lowering costs for a given population of patients with cirrhosis. If done correctly, we believe that such frameworks, once adopted, could help reduce burnout by freeing physicians of the burden of checking boxes in the electronic medical record so that they can devote their energies to managing populations. Conclusion: Value-based payment models for cirrhosis have the potential to benefit patients, physicians, and healthcare insurers.

Abstract
IL-1β is an important mediator of innate inflammatory responses and has been shown to contribute to liver injury in a number of etiologies. HIV patients have increased necroinflammation and more rapid fibrosis progression in chronic liver injury compared to non-HIV-infected patients. As the resident liver macrophage is critical to the IL-1β response to microbial translocation in chronic liver disease, we aim to examine the impact of HIV-1 and LPS stimulation on the IL-1β response of the resident hepatic macrophages. We isolated primary human liver macrophages from liver resection specimens, treated them with HIV-1BaL and/or LPS ex vivo, examined the IL-1β response, and then studied underlying mechanisms. Furthermore, we examined IL-1β expression in liver tissues derived from HIV-1 patients compared to those with no underlying liver disease. HIV-1 up-regulated TLR4 and CD14 expression on isolated primary CD68+ human liver macrophages and contributed to the IL-1β response to LPS stimulation as evidenced by TLR4 blocking. Nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) was shown to be involved in the IL-1β response of liver macrophages to HIV-1 infection and NLRP3 blocking experiments in primary CD68+ liver macrophages confirmed the contribution of the NLRP3-caspase 1 inflammatory signaling pathway in the IL-1β response. High in situ IL-1β expression was found in CD68+ cells in human liver tissues from HIV-1-infected patients, suggesting a critical role of IL-1β responses in patients infected by HIV. HIV infection sensitizes the IL-1β response of liver macrophages to LPS through up-regulation of CD14 and TLR4 expression and downstream activation of the NLRP3-caspase 1 pathway. These findings have implications for enhanced immune activation in HIV+ patients and mechanisms for rapid fibrosis progression in patients with chronic liver injury.

Abstract
AIM To assess the real-world effectiveness and cost of simeprevir (SMV), and/or sofosbuvir (SOF)-based therapy for chronic hepatitis C virus (HCV) infection.
METHODS The real-world performance of patients treated with SMV/SOF ± ribavirin (RBV), SOF/RBV, and SOF/RBV with pegylated-interferon (PEG) were analyzed in a consecutive series of 508 patients with chronic HCV infection treated at a single academic medical center. Patients with genotypes 1 through 4 were included. Rates of sustained virological response - the absence of a detectable serum HCV RNA 12 wk after the end of treatment [sustained virological response (SVR) 12] - were calculated on an intention-to-treat basis. Costs were calculated from the payer’s perspective using Medicare/Medicaid fees and Redbook Wholesale Acquisition Costs. Patient-related factors associated with SVR12 were identified using multivariable logistic regression.
RESULTS SVR12 rates were as follows: 86% (95%CI: 80%-91%) among 178 patients on SMV/SOF ± RBV; 62% (95%CI: 55%-68%) among 234 patients on SOF/RBV; and 78% (95%CI: 68%-86%) among 96 patients on SOF/PEG/RBV. Mean costs-per-SVR12 were $174442 (standard deviation: ± $18588) for SMV/SOF ± RBV; $223003 (± $77946) for SOF/RBV; and $126496 (± $31052) for SOF/PEG/RBV. Among patients on SMV/SOF ± RBV, SVR12 was less likely in patients previously treated with a protease inhibitor [odds ratio (OR): 0.20, 95%CI: 0.06-0.56]. Higher bilirubin (OR: 0.47, 95%CI: 0.30-0.69) reduced the likelihood of SVR12 among patients on SOF/RBV, while FIB-4 score ≥ 3.25 reduced the likelihood of SVR12 (OR: 0.18, 95%CI: 0.05-0.59) among those on SOF/PEG/RBV.
CONCLUSION SVR12 rates for SMV and/or SOF-based regimens in a diverse real-world population are comparable to those in clinical trials. Treatment failure accounts for 27% of costs.

Abstract
UNLABELLED Hepatitis C virus (HCV) is unique among RNA viruses in its ability to establish chronic infection in the majority of exposed adults. HCV persists in the liver despite interferon (IFN)-stimulated gene (ISG) induction; robust induction actually predicts treatment failure and viral persistence. It is unclear which forms of HCV RNA are associated with ISG induction and IFN resistance during natural infections. To thoroughly delineate HCV RNA populations, we developed conditions that fully separate the strands of long double-stranded RNA (dsRNA) and allow the released RNAs to be quantified in reverse transcription/polymerase chain reaction assays. These methods revealed that dsRNA, a pathogen-associated molecular pattern (PAMP), comprised 52% (standard deviation, 28%) of the HCV RNA in the livers of patients with chronic infection. HCV dsRNA was proportionally higher in patients with the unfavorable IL28B TT (rs12979860) genotype. Higher ratios of HCV double-stranded to single-stranded RNA (ssRNA) correlated positively with ISG induction. In Huh-7.5 cells, IFN treatment increased the total amount of HCV dsRNA through a process that required de novo viral RNA synthesis and shifted the ratio of viral dsRNA/ssRNA in favor of dsRNA. This shift was blocked by ribavirin (RBV), an antiviral drug that reduces relapse in HCV patients. Northern blotting established that HCV dsRNA contained genome-length minus strands. CONCLUSION HCV dsRNA is the predominant form in the HCV-infected liver and has features of both a PAMP and a genomic reservoir. Interferon treatment increased rather than decreased HCV dsRNA. This unexpected finding suggests that HCV produces dsRNA in response to IFN, potentially to antagonize antiviral defenses. (Hepatology 2017;66:357-370).

Abstract
BACKGROUND Patients who are chronically infected with hepatitis C virus (HCV) and who do not have a sustained virologic response after treatment with regimens containing direct-acting antiviral agents (DAAs) have limited retreatment options. METHODS We conducted two phase 3 trials involving patients who had been previously treated with a DAA-containing regimen. In POLARIS-1, patients with HCV genotype 1 infection who had previously received a regimen containing an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive either the nucleotide polymerase inhibitor sofosbuvir, the NS5A inhibitor velpatasvir, and the protease inhibitor voxilaprevir (150 patients) or matching placebo (150 patients) once daily for 12 weeks. Patients who were infected with HCV of other genotypes (114 patients) were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. In POLARIS-4, patients with HCV genotype 1, 2, or 3 infection who had previously received a DAA regimen but not an NS5A inhibitor were randomly assigned in a 1:1 ratio to receive sofosbuvir-velpatasvir-voxilaprevir (163 patients) or sofosbuvir-velpatasvir (151 patients) for 12 weeks. An additional 19 patients with HCV genotype 4 infection were enrolled in the sofosbuvir-velpatasvir-voxilaprevir group. RESULTS In the three active-treatment groups, 46% of the patients had compensated cirrhosis. In POLARIS-1, the rate of sustained virologic response was 96% with sofosbuvir-velpatasvir-voxilaprevir, as compared with 0% with placebo. In POLARIS-4, the rate of response was 98% with sofosbuvir-velpatasvir-voxilaprevir and 90% with sofosbuvir-velpatasvir. The most common adverse events were headache, fatigue, diarrhea, and nausea. In the active-treatment groups in both trials, the percentage of patients who discontinued treatment owing to adverse events was 1% or lower. CONCLUSIONS Sofosbuvir-velpatasvir-voxilaprevir taken for 12 weeks provided high rates of sustained virologic response among patients across HCV genotypes in whom treatment with a DAA regimen had previously failed.

Abstract
End-stage liver disease is a common cause of non-AIDS-related mortality in HIV+ patients, despite effective anti-retroviral therapies (ARTs). HIV-1 infection causes gut CD4 depletion and is thought to contribute to increased gut permeability, bacterial translocation, and immune activation. Microbial products drain from the gut into the liver via the portal vein where Kupffer cells (KCs), the resident liver macrophage, clear translocated microbial products. As bacterial translocation is implicated in fibrogenesis in HIV patients through unclear mechanisms, we tested the hypothesis that HIV infection of KCs alters their response to LPS in a TLR4-dependent manner. We showed that HIV-1 productively infected KCs, enhanced cell-surface TLR4 and CD14 expression, and increased IL-6 and TNF-α expression, which was blocked by a small molecule TLR4 inhibitor. Our study demonstrated that HIV infection sensitizes KCs to the proinflammatory effects of LPS in a TLR4-dependent manner. These findings suggest that HIV-1-infected KCs and their dysregulated innate immune response to LPS may play a role in hepatic inflammation and fibrosis and represent a novel target for therapy.

Abstract
AIM Activation of hepatic stellate cells and development of chronic inflammation are two key features in the progression of hepatic fibrosis. We have shown that in vitro activated stellate cells increase their expression of CXCL12 as well as the receptor CXCR4 and that receptor engagement promotes a profibrogenic phenotype. Furthermore, injury promotes increased hepatic expression of CXCL12 and a massive infiltration of CXCR4-expressing leukocytes, granulocytes and myeloid cells. The primary site of inflammatory cell accumulation is around the CXCL12-rich portal tracts and within fibrotic septae, indicating a role for CXCR4 during injury. In order to characterize the relevance of the CXCR4/CXCL12 chemokine axis during hepatic injury we inhibited the axis using AMD3100, a CXCR4 small molecule inhibitor, in models of chronic and acute liver injury. METHODS Mice were subjected to acute and chronic CCl4 liver injury with and without AMD3100 administration. The degree of liver injury, fibrosis and the composition of the intrahepatic inflammatory response were characterized. RESULTS Treatment of mice with AMD3100 in the chronic CCl4 model of liver injury led to an increase in hepatic inflammation and fibrosis with a specific increase in intrahepatic neutrophils. Furthermore, in an acute model of CCl4 -induced liver injury, AMD3100 led to an increase in the number of intrahepatic neutrophils and a trend towards worse necrosis. CONCLUSION Together, this data suggests that inhibition of the CXCR4/CXCL12 chemokine axis is injurious through modulation of the hepatic inflammatory response and that this axis may serve a protective role in liver injury.

Abstract
Hepatic expression levels of CXCL12, a chemokine important in inflammatory and stem cell recruitment, and its receptor, C-X-C chemokine receptor 4, are increased during all forms of liver injury. CXCL12 is expressed by both parenchymal and nonparenchymal hepatic cells, and on the basis of immunohistochemistry, biliary epithelial cells (BECs) are thought to be a predominant source of hepatic CXCL12, thereby promoting periportal recruitment of C-X-C chemokine receptor 4-expressing lymphocytes. Our study aims to show that BECs may, in fact, not be the predominant source of hepatic CXCL12. We measured CXCL12 secretion and expression from human and murine BECs using enzyme-linked immunosorbent assay and Western blot analysis from cell culture supernatants and whole cell lysates, respectively, whereas CXCL12 expression in murine livers was analyzed in a Cxcl12-Gfp reporter mouse. Cell culture supernatants and whole cell lysates from BECs failed to demonstrate their expression of CXCL12. Furthermore, we confirmed these results with a Cxcl12-Gfp reporter mouse in which green fluorescent protein expression is notably absent from BECs. Interestingly, on the basis of green fluorescent protein expression, we demonstrate a population of CXCL12-expressing cells within the portal tract that are distinct, yet intimately associated with BECs. These findings indicate that BECs are not a predominant source of CXCL12.

Abstract
Liver fibrosis, with subsequent development of cirrhosis and ultimately portal hypertension, results in the death of patients with end-stage liver disease if liver transplantation is not performed. Hepatic stellate cells (HSCs), central mediators of liver fibrosis, resemble tissue pericytes and regulate intrahepatic blood flow by modulating pericapillary resistance. Therefore, HSCs can contribute to portal hypertension in patients with chronic liver disease (CLD). We have previously demonstrated that activated HSCs express functional chemokine receptor, CXCR4, and that receptor engagement by its ligand, CXCL12, which is increased in patients with CLD, leads to further stellate cell activation in a CXCR4-specific manner. We therefore hypothesized that CXCL12 promotes HSC contraction in a CXCR4-dependent manner. Stimulation of HSCs on collagen gel lattices with CXCL12 led to gel contraction and myosin light chain (MLC) phosphorylation, which was blocked by addition of AMD3100, a CXCR4 small molecule inhibitor. These effects were further mediated by the Rho kinase pathway since both Rho kinase knockdown or Y-27632, a Rho kinase inhibitor, blocked CXCL12 induced phosphorylation of MLC and gel contraction. BAPTA-AM, a calcium chelator, had no effect, indicating that this pathway is calcium sensitive but not calcium dependent. In conclusion, CXCL12 promotes stellate cell contractility in a predominantly calcium-independent fashion. Our data demonstrates a novel role of CXCL12 in stellate cell contraction and the availability of small molecule inhibitors of the CXCL12/CXCR4 axis justifies further investigation into its potential as therapeutic target for portal hypertension.

Abstract
Adenosine is a potent modulator of liver fibrosis and inflammation. Adenosine has been shown to regulate such diverse activities as chemotaxis, contraction, and matrix production in hepatic stellate cells (HSC). Ecto-5'-nucleotidase/CD73 [EC 3.1.3.5] is the rate-limiting enzyme in adenosine production. Cd73-deficient mice are resistant to experimental liver fibrosis and have impaired adenosine generation. However, cell-specific expression and regulation of CD73 within the fibrotic liver have not been defined. In particular, prior evidence demonstrating that liver myofibroblasts, the cells believed to be responsible for matrix formation in the liver, express CD73 is lacking. Thus we tested the hypothesis that HSC and portal fibroblasts (PF), cells that undergo differentiation into liver myofibroblasts, express CD73 in a regulated fashion. We found that CD73 is weakly expressed in quiescent HSC and PF but is markedly upregulated at the transcriptional level in myofibroblastic HSC and PF. We furthermore found that CD73 protein and its functional activity are strongly increased in fibrous septa in rats subjected to experimental fibrosis. To determine the mechanism for the upregulation of Cd73 gene, we cloned the rat Cd73 promoter and then used serial truncation and site-directed mutagenesis to identify key regulatory elements. We identified two consensus SP1 motifs and one SMAD binding site, each of which was necessary for Cd73 gene upregulation. In conclusion, activated HSC upregulate Cd73 gene expression, via specific SP1 and SMAD promoter elements, after myofibroblastic differentiation. The ecto-5'-nucleotidase/CD73 enzyme is a novel cellular marker of activated liver myofibroblasts in vivo and in vitro and thus represents a promising molecular target for antifibrotic therapies in liver diseases.

Abstract
BACKGROUND AND AIMS Matrix metalloproteinase-2 (MMP-2), a type IV collagenase secreted by activated hepatic stellate cells (HSCs), is upregulated in chronic liver disease and is considered a profibrotic mediator due to its proliferative effect on cultured HSCs and ability to degrade normal liver matrix. Although associative studies and cell culture findings suggest that MMP-2 promotes hepatic fibrogenesis, no in vivo model has definitively established a pathologic role for MMP-2 in the development and progression of liver fibrosis. We therefore examined the impact of MMP-2 deficiency on liver fibrosis development during chronic CCl(4) liver injury and explored the effect of MMP-2 deficiency and overexpression on collagen I expression. METHODS Following chronic CCl(4) administration, liver fibrosis was analyzed using Sirius Red staining with quantitative morphometry and real-time polymerase chain reaction (PCR) in MMP-2-/- mice and age-matched MMP-2+/+ controls. These studies were complemented by analyses of cultured human stellate cells. RESULTS MMP-2-/- mice demonstrated an almost twofold increase in fibrosis which was not secondary to significant differences in hepatocellular injury, HSC activation or type I collagenase activity; however, type I collagen messenger RNA (mRNA) expression was increased threefold in the MMP-2-/- group by real-time PCR. Furthermore, targeted reduction of MMP-2 in cultured HSCs using RNA interference significantly increased collagen I mRNA and protein, while overexpression of MMP-2 resulted in decreased collagen I mRNA. CONCLUSIONS These findings suggest that increased MMP-2 during the progression of liver fibrosis may be an important mechanism for inhibiting type I collagen synthesis by activated HSCs, thereby providing a protective rather than pathologic role.

Abstract
UNLABELLED Patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) develop more rapid fibrosis than those infected with HCV only. In HIV/HCV-coinfected patients, fibrosis progression correlates with HIV RNA levels, suggesting a direct role of HIV in liver fibrogenesis. Chemokine (C-C motif) receptor 5 (CCR5) and cysteine-X-cysteine receptor 4 (CXCR4), the two major coreceptors required for HIV entry into cells, are expressed on activated hepatic stellate cells (HSCs), the principle fibrogenic cell type in the liver. We therefore examined whether HIV can infect HSCs, explored the potential mechanisms of viral entry, and assessed the impact of infection as reflected by the ability of HSCs to transfer virus to T lymphocytes and elicit a proinflammatory and profibrogenic response. We report that the laboratory-adapted viruses HIV-IIIB (CXCR4-tropic or X4) and HIV-BaL (CCR5-tropic or R5) and primary HIV isolates can infect both a human stellate cell line, LX-2, and primary human HSCs. HIV entry and gene expression in HSCs was confirmed using HIV-green fluorescent protein (GFP) expression viral constructs in the presence or absence of the reverse-transcriptase inhibitor azidothymidine. CD4 expression on a subset of primary HSCs was demonstrated using fluorescence-activated cell sorting and immunofluorescence staining. Blocking experiments in the presence of anti-CD4, anti-CXCR4, and anti-CCR5 revealed that HIV entry into HSCs is predominantly CD4/chemokine coreceptor-independent. HIV infection promoted HSC collagen I expression and secretion of the proinflammatory cytokine monocyte chemoattractant protein-1. Furthermore, infected LX-2 cells were capable of transferring GFP-expressing virus to T lymphocytes in a coculture system. CONCLUSION Taken together, our results suggest a potential role of HIV in liver fibrosis/inflammation mediated through effects on HSCs. The role of early highly active antiretroviral therapy initiation in patients with HIV/HCV coinfection warrants further investigation.

Abstract
UNLABELLED Chemokine interactions with their receptors have been implicated in hepatic stellate cell (HSC) activation. The hepatic expression of CXCR4 messenger RNA is increased in hepatitis C cirrhotic livers and plasma levels of its endogenous ligand, stromal cell-derived factor-1alpha (SDF-1alpha), correlate with increased fibrosis in these patients. The expression of CXCR4 by HSCs has not been reported. We therefore examined whether HSCs express CXCR4 in vivo and in vitro and explored whether SDF-1alpha/CXCR4 receptor engagement promotes HSC activation, fibrogenesis, and proliferation. The hepatic protein expression of both CXCR4 and SDF-1alpha is increased in hepatitis C cirrhotic livers and immunoflourescent and immunohistochemical staining confirms that HSCs express CXCR4 in vivo. Immortalized human stellate cells as well as primary human HSCs express CXCR4, and cell surface receptor expression increases with progressive culture-induced activation. Treatment of stellate cells with recombinant SDF-1alpha increases expression of alpha-smooth muscle actin and collagen I and stimulates a dose-dependent increase in HSC proliferation. Inhibitor studies suggest that SDF-1alpha/CXCR4-dependent extracellular signal-regulated kinase 1/2 and Akt phosphorylation mediate effects on collagen I expression and stellate cell proliferation. CONCLUSION HSCs express CXCR4 receptor in vivo and in vitro. CXCR4 receptor activation by SDF-1alpha is profibrogenic through its effects on HSC activation, fibrogenesis, and proliferation. Extracellular signal-regulated kinase 1/2 and phosphoinositide 3-kinase pathways mediate SDF-1alpha-induced effects on HSC expression of collagen I and proliferation. The availability of small molecule inhibitors of CXCR4 make this receptor an appealing target for antifibrotic approaches.

Abstract
The prospect of reversing hepatic fibrosis has generated great interest now that basic science advances are being translated into promising new antifibrotic therapies. It is appropriate to recognize both the historical advances that created the framework for these successes, and the important role that Hepatology has played in disseminating them. A sense of urgency underlies this effort as the epidemics of HCV and NASH are becoming associated with advancing fibrosis. To maintain progress and minimize confusion among investigators and clinicians it is essential to standardize terms referring to fibrosis 'reversal' and 'regression.' There must also be rapid optimization of non-invasive markers of fibrosis to relieve this current bottleneck to conducting clinical trials. Progress in identifying genetic determinants of fibrosis could further refine patient selection for clinical trials and shorten their duration, as well as unearthing new directions of scientific inquiry. Realistic expectations for successful anti-fibrotic therapies reflect solid evidence of fibrosis regression in patients treated effectively for viral liver disease, as well as growing clarity in the understanding mechanisms of extracellular matrix production and degradation. The paradigms of stellate cell activation and apoptosis remain valuable frameworks for understanding pathways of hepatic fibrogenesis and fibrosis regression, respectively. Continued progress is essential in order to identify the determinants and dynamics of fibrosis reversibility, to discover additional targets for anti-fibrotic therapy, and to develop customized multi-drug regimens. These advances are sure to be captured in the next 25 years by Hepatology , and to profoundly impact the prognosis of patients with chronic liver disease.

Abstract
OBJECTIVE Matrix metalloproteinases (MMP) are critical to smooth muscle cell (SMC) migration in vivo. MMP-2 dysregulation has been implicated in the pathogenesis of abnormal arterial remodeling, aneurysm formation, and atherosclerotic plaque structure and stability. The chemokine receptors CCR3 and CXCR4 are present and functional on SMC and are up-regulated in vascular diseases such as atherosclerosis. We sought to determine a potential mechanism for chemokine receptor-mediated effects on the vasculature by asking whether the chemokines eotaxin (CCL11), the ligand for CCR3, and stromal cell-derived cell factor (SDF-1, CXCL12), the ligand for CXCR4, induce MMP-2 in SMC. Studies were then performed to define the signaling pathways involved. METHODS AND RESULTS As determined by RT-PCR, Western blotting and zymography, SDF-1 and eotaxin induce MMP-2 mRNA, protein, and activity in SMC. An anti-CCR3 antibody and a CXCR4 antagonist blocked proMMP-2 induction by SDF-1 and eotaxin, the respective ligands for the chemokine receptors CXCR4 and CCR3, suggesting that the inductions by these chemokines are receptor-mediated. Receptor cross-talk between G-protein-coupled receptors (GPCR) and the epidermal growth factor receptor (EGFR) is a method of expanding the GPCRs' signaling repertoire. We demonstrate, for the first time to our knowledge, that in SMC, chemokine induction of proMMP-2 is dependent on activation of the EGFR. Interestingly, by blocking the ligand binding domain of EGFR, we demonstrate that activation of EGFR by SDF-1 and eotaxin occurs through different cellular pathways. CONCLUSION The pro-inflammatory chemokines eotaxin and SDF induce proMMP-2 activation of EGFR through two different pathways. SDF and eotaxin, as regulators of proMMP-2 expression and by engaging in receptor cross-talk, may play critical roles in atherosclerosis, restenosis, and plaque rupture. These ligands and their respective receptors, CXCR4 and CCR3, therefore may serve as future potential therapeutic targets.

Abstract
BACKGROUND/AIMS Interleukin-6 stimulates liver regeneration and promotes hepatoprotection following experimental liver injury, but underlying mechanisms have not been fully characterized. Because studies suggest matrix metalloproteinase-2 (MMP-2) may promote liver injury, we examined whether IL-6 exerted its protective effects via regulation of MMP-2. METHODS MMP-2 was analyzed in livers of IL-6-/- and IL-6+/+ mice following CCl(4) administration. IL-6-/- mice were pretreated with IL-6 and liver histology and MMP-2 expression were examined after liver injury. IL-6-/- mice were treated with an MMP-2 inhibitor and assessment of injury (histology and serum ALT levels), apoptosis by TUNEL assay, and hepatocyte proliferation by BRDU-labeling was performed. These studies were complemented by analysis of cultured stellate cells. RESULTS MMP-2 mRNA, protein, and activity was increased in IL-6-/- livers. Restoration of IL-6 signaling in IL-6-/- mice rescued injury and restored MMP-2 expression to wild-type levels. Furthermore, pharmacologic inhibition of MMP-2 decreased hepatocellular injury and apoptosis in IL-6-/- mice. In cultured stellate cells, recombinant IL-6 suppressed endogenous MMP-2 mRNA and protein expression. CONCLUSIONS IL-6 may be hepatoprotective in acute injury through down-regulation of MMP-2. These findings suggest a role for MMP-2 in amplifying liver injury in vivo.

Abstract
Enoxacin, a new 6-fluoroquinolone known to be active in vitro against most common pulmonary pathogens, was evaluated in comparison with ceftazidime, a third generation cephalosporin proven to be effective in the treatment of gram negative pneumonias. Clinical and microbiologic responses to therapy were satisfactory and comparable in both antibiotic groups. Enoxacin could be an effective alternative choice in the treatment of lower respiratory tract infections caused by gram negative organisms.

Abstract
This prospective, randomized controlled study compared the efficacy and safety of ciprofloxacin alone versus a conventional two-drug regimen, clindamycin with gentamicin. The study group included 71 patients hospitalized for pelvic infections such as acute (N = 33) and chronic (N = 8) salpingitis, tubo-ovarian abscesses (N = 11), endometritis (N = 9), septic abortion (N = 3), and other categories (N = 7). Twenty-two of 35 patients on ciprofloxacin and 20 of 36 on clindamycin plus gentamicin had culturable pathogens: gonococci in 28, anaerobes in six, chlamydia in four, and associated pathogens in 19. Complete clinical and bacteriologic cure was achieved in 21 of 22 (95%) in the ciprofloxacin group and 19 of 20 (95%) in the clindamycin plus gentamicin group. The mean duration of intravenous/oral ciprofloxacin therapy was 3.7/7.2 days, and it was 3/6.6 days for clindamycin plus gentamicin. Ciprofloxacin, a new quinolone, appears to be safe as a single-drug therapy and was as effective as the combination of clindamycin plus gentamicin for the treatment of severe pelvic infections requiring hospitalization.

Abstract
Intravenous ciprofloxacin therapy was evaluated in comparison with i.v. ceftazidime in the treatment of skin and soft tissue infections and were found to be comparable. Intravenous or peroral forms of ciprofloxacin may be used instead of intravenously given third generation cephalosporins or aminoglycosides in the treatment of even severe infections of the skin and soft tissue.

Abstract
The effects of alterations in pH, size of inoculum, addition of human serum, and repeated exposure to sub-minimum inhibitory concentration of ciprofloxacin against anaerobic bacteria were assessed. Increase in the size of the inoculum and human serum had no effect on the minimum inhibitory concentration, whereas decrease in pH and exposure to sub-MIC decreased the activity of ciprofloxacin against Bacteroides fragilis. We tested for synergism of ciprofloxacin with cefoxitin, clindamycin and metronidazole against B. fragilis.

Abstract
Ciprofloxacin at a concentration of 2 micrograms/mL inhibited the growth of approximately 90% of 584 strains of aerobic bacteria isolated from cultures of blood drawn from septicemic patients. An increase in the inoculum size did not result in an increased MIC, but serial passages through media containing ciprofloxacin at sub-MIC levels increased the MIC for Escherichia coli, Klebsiella pneumoniae, and Proteus vulgaris. In experimental subcutaneous abscesses in the mouse model, ciprofloxacin was more active than cefotaxime against a mixed infection induced with E. coli and Bacteroides fragilis. Against mixed E. coli and Staphylococcus aureus infection, no significant differences were noted between the two drugs. In a double-blind, prospective, randomized clinical study, perorally administered ciprofloxacin was compared with intravenously administered cefotaxime in the treatment of skin and soft-tissue infections severe enough to require hospitalization. In 70 patients treated, the therapeutic efficacy of peroral ciprofloxacin was comparable to that of intravenous cefotaxime, with two differences: S. aureus infections responded less favorably to oral ciprofloxacin (62%) than to intravenous cefotaxime (90%), and aerobic gram-negative bacillary infections responded more favorably to ciprofloxacin (92%) than to cefotaxime (64%).

Abstract
We determined the MICs of difloxacin (A-56619) and A-56620 against anaerobic bacteria and assessed the effects of alterations in pH, size of inoculum, addition of human serum, and repeated exposure to subinhibitory levels of antibiotics. We tested for synergism of these drugs with cefoxitin against Bacteroides spp. We found that difloxacin and A-56620 were as active as ciprofloxacin, inhibiting about 90% of B. fragilis (4 micrograms/ml) and other Bacteroides spp. (8 micrograms/ml), A-56620 being more active than difloxacin against several isolates. Increased inoculum size and changes in pH did not alter their MICs much, but human serum and exposure to sub-MICs of antibiotic effected increases in their MICs against Bacteroides spp. Cefoxitin was not synergistic with either difloxacin or A-56620 against B. fragilis.

Abstract
The combination of clavulanic acid (CA) with penicillin or ticarcillin was evaluated in a rat intra-abdominal abscess model. Gelatin capsules filled with a mixture of Bacteroides fragilis and Escherichia coli were implanted intraperitoneally in male Wistar rats. Four different groups of animals with appropriate controls were treated with penicillin or ticarcillin alone or in combination with CA. The treatment was started either immediately or delayed for 48 h after peritoneal inoculation. The therapeutic regimen was given for ten days at 8-hourly intervals. The mortality rate decreased to almost one-half when antibiotic therapy was started within 6 h. Seventy-nine to 89% of animals were cured when treated with ticarcillin in combination with CA showing that ticarcillin + CA was the most effective regimen of those tested in the treatment of experimental intra-abdominal abscess of rats caused by Bact. fragilis and E. coli.

Abstract
A formulation of 3.0 g of ticarcillin and 0.1 g of clavulanic acid was evaluated in the treatment of skin and soft tissue infections, and its efficacy was compared with that of moxalactam in a randomized open study. Thirty-three patients received 3.1 g of ticarcillin plus clavulanic acid every six hours via intravenous infusion, and 36 patients received 2.0 g of moxalactam every eight hours via intravenous infusion. Diagnostic categories included intramuscular abscesses, cellulitis, skin ulcers, gangrene, and perirectal abscesses. The average age of the patients and the duration of therapy were similar in both groups. Overall, 45 aerobic and 25 anaerobic bacteria were isolated from the ticarcillin plus clavulanic acid-treated patients; 58 aerobic and 24 anaerobic bacteria were isolated from the moxalactam-treated patients. Thirty of 33 patients in the ticarcillin plus clavulanic acid-treated group had a satisfactory response; a skin rash developed in one patient; therapy failed in one patient with Staphylococcus aureus infection; and one patient died as a result of a bleeding peptic ulcer. In the moxalactam-treated group, 32 of 36 patients had a satisfactory response; a skin rash developed in one patient; therapy failed in a patient with Pseudomonas aeruginosa infection; and two patients were unevaluable. Ticarcillin plus clavulanic acid as a single agent was found to be as effective as moxalactam in the treatment of skin and soft tissue infections.

Abstract
The efficacy of ticarcillin plus clavulanic acid was compared with that of certain broad-spectrum antibiotics such as ticarcillin, azlocillin, and piperacillin against blood culture isolates of aerobic bacteria obtained from seriously ill patients and anaerobic bacteria obtained from other miscellaneous infections. Ticarcillin plus clavulanic acid was found to be as effective as other broad-spectrum antibiotics against most of the 285 septicemic isolates tested. Ticarcillin plus clavulanic acid was most effective against 351 anaerobic bacteria, including B. fragilis. Further, 32 strains of B. fragilis that were relatively resistant to ticarcillin and azlocillin were tested with a mixture of ticarcillin or azlocillin, each in combination with clavulanic acid. Ticarcillin plus clavulanic acid inhibited all 32 strains of B. fragilis. Addition of clavulanic acid to cephalothin, penicillin, or azlocillin also augmented the antibiotic activity against B. fragilis by 4- to 64-fold. These in vitro data suggest that ticarcillin plus clavulanic acid may be used as a single antibiotic in the cases of bacterial septicemias and that the combination may be used in the treatment of multiple-antibiotic-resistant bacterial strains. In a related study, the augmentation activity of clavulanic acid with penicillin or ticarcillin was evaluated against B. fragilis in a rat intra-abdominal abscess model. Gelatin capsules filled with a mixture of B. fragilis and Escherichia coli were implanted intraperitoneally in male Wistar rats. Four different groups of animals with appropriate controls were treated with penicillin or ticarcillin alone or in combination with clavulanic acid. Treatment was started immediately or delayed for 48 hours after peritoneal soilage. The mortality rate decreased by almost one half when antibiotic therapy was started immediately. Treatment with ticarcillin plus clavulanic acid resulted in a cure in 70 to 89 percent of animals, showing that this combination is the most effective regimen in the treatment of rats with experimental intra-abdominal abscesses caused by B. fragilis and E. coli.

Abstract
Cefmenoxime, a new third-generation cephalosporin, was used as a single drug in the therapy for female genital tract infections. Therapeutic response was considered satisfactory in 21 of 22 cases of pelvic inflammatory disease, six of nine tuboovarian abscesses, two of three severe wound infections, and all five cases of endometritis. Overall, 34 of 39 patients responded. The peak serum antibiotic levels in this study ranged from 15.8 to 64 (average 48.7) micrograms/mL, and the trough level ranged from 0.9 to 4 (average 3.1) micrograms/mL. Cefmenoxime was tested in vitro against 424 isolates of anaerobes including 208 strains of bacteroides of which 80 were Bacteroides fragilis. Cefmenoxime inhibited the growth of 90% or greater of the organisms (minimal inhibitory concentration 90) at less than or equal to 64 micrograms/mL. The minimal inhibitory concentration for 75% of B fragilis was 32 micrograms/mL. This study suggests that cefmenoxime as a single-drug therapy is effective in the treatment of female genital tract infections caused by aerobic (including the gonococcus) and anaerobic bacteria.

Abstract
The 90% MIC of cefbuperazone (BMY 25182) was 32 micrograms/ml for Bacteroides fragilis and Bacteroides spp., 128 micrograms/ml for Fusobacterium and Clostridium spp., 64 micrograms/ml for Eubacterium and Peptococcus spp., 8 micrograms/ml for Actinomyces spp., and 32 micrograms/ml for Peptostreptococcus spp. The level of activity of cefbuperazone was higher against B. fragilis and lower against anaerobic cocci than those of related cephalosporins, i.e., cefoxitin, cefoperazone, cefotaxime, ceftizoxime, and cefmenoxime. However, the activity of cefbuperazone was comparable to that of moxalactam against all groups tested. Size of inoculum and type of media used did not alter the MICs of cefbuperazone for B. fragilis. Cefbuperazone showed synergistic activity when combined with cefoxitin against resistant strains of B. fragilis.

Abstract
The effect of clavulanic acid on the in vitro activity of beta-lactam antibiotics against Bacteroides fragilis (154 strains) was tested. The MIC90 on 154 strains of B. fragilis tested was greater than 64 micrograms/ml for penicillin and cephalothin, and greater than 128 for ticarcillin alone. 32 strains of B. fragilis relatively resistant to the test beta-lactam antibiotics (most of them beta-lactamase producers) were retested with the addition of clavulanic acid. 90% of the strains were then inhibited by less than or equal to 8 micrograms/ml of penicillin and cephalothin, and by 32 micrograms/ml of ticarcillin. The strongest beta-lactamase producers were the most susceptible, and this was not influenced by change in pH of the diluent for clavulanic acid from 6.0 to 7.4. Both penicillin and cephalothin when combined with clavulanic acid were highly effective against B. fragilis but the therapeutic relevance of these combinations remains to be evaluated.

Abstract
Azlocillin was active against 90% of 154 strains of Bacteroides fragilis at a concentration of 64 micrograms/ml. Twenty-eight strains of B. fragilis with an azlocillin MIC of greater than or equal to 8 micrograms/ml were retested with a combination of azlocillin plus clavulanic acid. Of these strains, 71% showed a 4- to 32-fold decrease in the MIC of azlocillin plus clavulanic acid.

Abstract
Antistaphylococcal activity of three beta-lactam antibiotics, i.e. cefmenoxime, cefotaxime and latamoxef (moxalactam) was compared with that of nafcillin by studying cure rates of aortic valvular endocarditis caused by one of three clinical isolates of Staphylococcus aureus in New Zealand white male rabbits. The animals were randomly allocated to a control and four antibiotic treatment groups. Each animal except the controls received 60 mg/kg of one antibiotic intramuscularly twice daily for two weeks, beginning 24 h after induction of endocarditis. The aortic valve was sterilized in 11 of 15 (73%) animals treated with cefmenoxime, nine of 13 (69%) treated with cefotaxime, 11 of 13 (85%) treated with latamoxef and 12 of 15 (80%) treated with nafcillin. All nine animals in the control group developed aortic valvular vegetations with an average of 2.4 X 10(9) cfu/g. The differences in sterility rates resulting from treatment with the four antibiotics were not statistically significant (P greater than 0.70).

Abstract
In vitro susceptibility of 473 isolates of anaerobic bacteria derived from patients hospitalized for treatment of abdominal trauma was tested against third-generation cephalosporins--moxalactam, cefotaxime, ceftizoxime, cefmenoxime--and a penicillin--N-formimidoyl thienamycin--by serial agar dilution method in the anaerobic glove box. There were 208 Bacteroides isolates including 80 Bacteroides fragilis and 100 peptococci and peptostreptococci. The minimal inhibitory concentration (MIC) 75% of B. fragilis was less than or equal to 32 micrograms/ml for the cephalosporins tested and less than or equal to 8 micrograms/ml for thienamycin. The MIC of B. fragilis and Bacteroides vulgatus was not much influenced by increased inoculum size. Characteristically, peptostreptococci and peptococci were resistant to all four cephalosporins tested with MIC 75% being 32-64 micrograms/ml. All five antibiotics in this study appear suitable for therapy of intraabdominal suppurative infections, but the poor activity of third-generation cephalosporins on anaerobic cocci can be a cause of concern.

Abstract
Carbenicillin, piperacillin, and mezlocillin, when combined with cefoxitin, exhibited synergism against 20, 13, and 10 isolates of Bacteroides fragilis, respectively, and no antagonism was observed in 19 of 20 strains. These results suggest that if beta-lactamase was induced from B. fragilis by cefoxitin, it was ineffective against the antibiotics tested.

Abstract
In vitro activity of pipecolic acid amide of clindamycin (U-57930E) against 265 isolates of anaerobic bacteria, including 66 strains of Bacteroides fragilis, was compared with those of clindamycin, chloramphenicol, and cefoxitin. At therapeutically achievable concentrations, the activities of all four antibiotics against anaerobic bacteria were similar.

Abstract
The antimicrobial efficacy of BU-2313B, a new antibiotic, was evaluated in comparison with clindamycin, chloramphenicol and cefoxitin against 265 clinical anaerobic isolates. BU-2313B inhibited 88% of 66 isolates of Bacteroides fragilis tested at 2 micrograms/ml, whereas clindamycin, chloramphenicol and cefoxitin inhibited 98, 97 and 92% of them at 2, 8 and 16 micrograms/ml, respectively. BU-2313B was severalfold more effective than chloramphenicol and cefoxitin, but it was eight times less effective than clindamycin.
