Objective We aimed to define the clinical features of liver dysfunction in patients with systemic lupus erythematosus (SLE). Methods The frequency and causes of liver dysfunction were examined in 206 patients with SLE. Results Liver dysfunction was evident in 123 (59.7%) of the 206 patients. Liver dysfunction in patients with SLE can be drug-induced (30.9%) or caused by SLE itself (28.5%), fatty liver (17.9%), autoimmune hepatitis (AIH) (4.9%), primary biliary cirrhosis (2.4%), cholangitis (1.6%), alcohol (1.6%) or viral hepatitis (0.8%), and it tends to be mild except when caused by AIH. Values for aminotransferase were significantly increased when AIH was the cause, whereas alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (γ-GTP) were significantly increased when AIH or drugs were the cause. The liver was already dysfunctional at the time of SLE onset in 56 (45.5%) of 123 patients with liver dysfunction. Neurological involvement was more common among patients with than without liver dysfunction, whereas SLE activity and prognosis did not significantly differ between the two groups. Conclusion Liver dysfunction in the presence of SLE can be caused by many factors, but when extant at the time of SLE onset, either SLE itself or drugs can be the cause. Autoimmune hepatitis should be considered when liver dysfunction is relatively severe.
A review of functional brain imaging studies of bladder control in participants with normal control and pathological conditions. In the normal condition, bladder and urethral afferents received in the periaqueductal gray relay the information to the insula, the anterior cingulate cortex and the prefrontal cortex. During the storage phase, these superior regions control the pontine micturition center to inhibit voiding. In overactive bladder patients, brain responses are different. Cortical responses become exaggerated, especially in the anterior cingulate cortex and the supplementary motor area. That is what presumably evokes the "urgency". The supplementary motor area is activated during contraction of the pelvic floor muscles, and provides protection against incontinence. We believe that functional brain imaging studies are promising not only for the understanding of bladder dysfunction, but also as an aid to the development of therapeutic options for chronic disorders.
To date, only limited evidence has supported the notion that resistance exercise positively impacts non-alcoholic fatty liver disease. We evaluated the effects of resistance exercise on the metabolic parameters of non-alcoholic fatty liver disease (NAFLD) in 53 patients who were assigned to either a group that performed push-ups and squats 3 times weekly for 12 weeks (exercise group; n=31) or a group that did not (control; n=22). Patients in the control group proceeded with regular physical activities under a restricted diet throughout the study. The effects of the exercise were compared between the 2 groups after 12 weeks. Fat-free mass and muscle mass significantly increased, whereas hepatic steatosis grade, mean insulin and ferritin levels, and the homeostasis model assessment-estimated insulin resistance index were significantly decreased in the exercise group. Compliance with the resistance exercise program did not significantly correlate with patient background characteristics such as age, sex, BMI and metabolic complications. These findings show that resistance exercise comprising squats and push-ups helps to improve the characteristics of metabolic syndrome in patients with non-alcoholic fatty liver disease.
Background: Coexistence of primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) is referred to as PBC-AIH overlap. Pathogenesis of PBC-AIH is not well understood and its diagnosis is challenging. We previously reported the clinical characteristics of 10 patients diagnosed with PBC-AIH overlap. Aims: The aim of the study was extend the earlier series and evaluate the diagnostic criteria, biological characteristics, potential therapy, and long-term outcomes of patients with PBC-AIH overlap. Methods and Results:We retrospectively analyzed clinical, biochemical, and histological characteristics of 144 patients diagnosed with PBC and 73 diagnosed with AIH. We identified 16 cases of PBC-AIH overlap, according to criteria established by Chazouillères et al. and other studies. PBC preceded AIH in 6 patients and both diseases occurred simultaneously in the remaining 10 patients. PBC-AIH overlap has clinical, biochemical, and histological characteristics of both PBC and AIH. Thirteen patients treated with both ursodeoxycholic acid (UDCA) and immunosuppressive therapy responded well, with normal alanine aminotransferase (ALT) and alkaline phosphatase (ALP) levels. The remaining three patients treated with either prednisolone (PSL) or UDCA alone developed cirrhosis, varices, ascites, encephalopathy, or died of liver-related causes at the 5, 12, and 14-year follow up. Conclusions: PBC-AIH overlap is not a rare entity; it was observed in 11% of PBC patients in this study. Further studies will be required to investigate whether PBC-AIH overlap is distinct from the two individual diseases in terms of long-term outcomes and therapeutic implications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
