Viral B and C hepatitis are a major current health issue, both diseases having a chronic damaging effect on the liver and its functions. Chronic liver disease can lead to even more severe and life-threatening conditions, such as liver cirrhosis and hepatocellular carcinoma. Recent years have uncovered an important interplay between the liver and the gut microbiome: the gut-liver axis. Hepatitis B and C infections often cause alterations in the gut microbiota by lowering the levels of ‘protective’ gut microorganisms and, by doing so, hinder the microbiota ability to boost the immune response. Treatments aimed at restoring the gut microbiota balance may provide a valuable addition to current practice therapies and may help limit the chronic changes observed in the liver of hepatitis B and C patients. This review aims to summarize the current knowledge on the anato-functional axis between the gut and liver and to highlight the influence that hepatitis B and C viruses have on the microbiota balance, as well as the influence of treatments aimed at restoring the gut microbiota on infected livers and disease progression. 相似文献

Radiographic contrast nephropathy (RCN), acute worsening of renal function due to contrast agents, can occur in 15%-40% of patients with baseline renal dysfunction undergoing percutaneous coronary intervention (PCI) and is associated with increased morbidity and in-hospital mortality. The purpose of this study was to evaluate whether the selective dopamine-1 (DA-1) receptor agonist fenoldopam would be beneficial in patients with chronic renal insufficiency (CRI) undergoing PCI and also to design a protocol for prevention of RCN. We analyzed 150 consecutive patients with CRI [baseline serum creatinine (BSCr) +/- 1.5% mg] who underwent PCI and received fenoldopam during and after the procedure, in addition to saline hydration. RCN, defined as > 25% increase of BSCr 48-72 hr after PCI, occurred in 4.7% (n = 7) of 150 PCI patients receiving fenoldopam and 3.5% in diabetics (n = 85) vs. 6.1% in nondiabetics (n = 65; P = NS). No patients required dialysis. The observed 4.7% incidence of RCN with fenoldopam was significantly lower than 18.8% incidence in the historical control group (P < 0.001). Our data suggest that fenoldopam is a useful adjunct in the prevention of RCN during PCI, especially in diabetics. 相似文献

We sought to determine whether Litomosoides sigmodontis, a filarial infection of rodents, protects against type 1 diabetes in non‐obese diabetic (NOD) mice. Six‐week‐old NOD mice were sham‐infected or infected with either L3 larvae, adult male worms, or adult female worms. Whereas 82% of uninfected NOD mice developed diabetes by 25 weeks of age, no L. sigmodontis‐infected mice developed disease. Although all mice had evidence of ongoing islet cell inflammation by histology, L. sigmodontis‐infected mice had greater numbers of total islets and non‐infiltrated islets than control mice. Protection against diabetes was associated with a T helper type 2 (Th2) shift, as interleukin‐4 (IL‐4) and IL‐5 release from α‐CD3/α‐CD28‐stimulated splenocytes was greater in L. sigmodontis‐infected mice than in uninfected mice. Increased circulating levels of insulin‐specific immunoglobulin G1, showed that this Th2 shift occurs in response to one of the main autoantigens in diabetes. Multicolour flow cytometry studies demonstrated that protection against diabetes in L. sigmodontis‐infected NOD mice was associated with significantly increased numbers of splenic CD4+ CD25+ FoxP3+ regulatory T cells. Interestingly, injection of crude worm antigen into NOD mice also resulted in protection against type 1 diabetes, though to a lesser degree than infection with live L. sigmodontis worms. In conclusion, these studies demonstrate that filarial worms can protect against the onset of type 1 diabetes in NOD mice. This protection is associated with a Th2 shift, as demonstrated by cytokine and antibody production, and with an increase in CD4+ CD25+ FoxP3+ regulatory T cells. 相似文献

SUMMARY
Filarial worms cause highly morbid diseases such as elephantiasis and river blindness. Since the 1940s, researchers have conducted vaccine trials in 27 different animal models of filariasis. Although no vaccine trial in a permissive model of filariasis has provided sterilizing immunity, great strides have been made toward developing vaccines that could block transmission, decrease pathological sequelae, or decrease susceptibility to infection. In this review, we have organized, to the best of our ability, all published filaria vaccine trials and reviewed them in the context of the animal models used. Additionally, we provide information on the life cycle, disease phenotype, concomitant immunity, and natural immunity during primary and secondary infections for 24 different filaria models. 相似文献8.

The manifestations of many congenital and acquired conditions can be seen in the ribs of children. Normal variants are usually clinically insignificant; they are occasionally palpated at clinical examination or detected incidentally at chest radiography. Signs of abnormality can appear in the ribs as variations in number, size, mineralization, and shape. These changes can be focal or generalized. Abnormalities detected in the ribs may be the initial indication of previously unsuspected systemic disease. The ribs can yield important diagnostic clues in the work-up of patients with congenital bone dysplasias, acquired metabolic diseases, iatrogenic conditions, trauma (especially child abuse), infection, and neoplasms. Routine evaluation of the ribs on every chest radiograph is important so that valuable diagnostic data will not be overlooked. The diagnostic information obtained from evaluation of the ribs can help tailor the radiologic and laboratory studies that may be necessary to complete a patient's diagnostic work-up. 相似文献
