Lupus-like reactions in patients with inflammatory bowel disease treated with anti-TNFs are insidious adverse events: data from a large single-center cohort.

Objectives: Very few data on the incidence, predictors, and clinical outcomes of lupus-like reactions (LLRs) in patients with inflammatory bowel disease (IBD) treated with anti-TNFs have been reported. Materials and methods: All records of consecutive IBD patients who started a treatment with an anti-TNF from January 2006 to June 2018 were retrospectively reviewed. Patients were defined as having LLR by the presence of immunologic abnormalities (positivity for ANA and/or anti-ds-DNA), along with clinical features that included at least two of the following: arthralgia, fatigue, fever, cutaneous manifestations, or serositis, which had a clear temporal association with exposure to the anti-TNFs, and resolved without recurrence once the drug was discontinued. Results: 760 patients (1059 total treatments with anti-TNFs) were included. Participants contributed a total of 2863.5 person-years of follow-up, during which 16 cases of LLRs (2.1% of patients) were reported, accounting for an incidence rate of 5.6 per 1000 person-years. Female gender and being former smokers were more prevalent in the LLR group (75.0% versus 44.1%, p = .02; and 18.8% versus 5.4%, p = .037, respectively), with a hazard ratio of 4.40 (95% CI: 1.40-13.81; p = .011) and 4.87 (95% CI: 1.37-17.38; p = .015), respectively, at Cox regression analysis. All LLRs resolved following discontinuation of the drug after a mean of 8.1 ± 4.2 weeks. Ten patients required corticosteroids to control severe symptoms. Conclusions: In this large cohort of patients treated with anti-TNFs with long follow-up, LLRs were rare adverse events, more common in women and former smokers, occurring with nonspecific and insidious clinical features.

Psoriasis and Inflammatory Bowel Disease.

BACKGROUND: Inflammatory bowel disease (IBD) and psoriasis (PS) are associated conditions. The reason for this association lies in the sharing of predisposition genes and common immunological mechanisms. SUMMARY: This review will focus on the interplay between IBD and PS, with details on prevalence and phenotype of PS in IBD, genetics, pathogenetic pathways, and therapy. Key Messages: Microbiome seems relevant in both conditions: a reduction of beneficial bacteria has been observed. IBD and PS have in common some comorbidities like cardiovascular disease, similar risk of cancer and psychiatric problems. Many biological therapies such as anti-tumour necrosis factor (TNF) and anti-interleukin 23 are effective in both conditions, underlining the common immunological mechanisms. Paradoxical PS has been mainly observed after anti-TNF therapies, but preliminary reports show that it can also occur with other biologics. Genetic predisposition to this phenomenon has been reported.

Tolerability profile of thiopurines in inflammatory bowel disease: a prospective experience.

OBJECTIVES: The occurrence of thiopurine-related adverse events (AEs) may complicate the management of patients with inflammatory bowel disease (IBD). We aimed to evaluate the tolerability of thiopurines in a current IBD setting. MATERIALS AND METHODS: All consecutive patients who started a treatment with azathioprine (AZA) from January 2010 to March 2016 were entered in a prospectively maintained database, and the AEs which led to the permanent discontinuation of the drug were reported. RESULTS: Two hundred and fifty three patients were included. Median total follow-up was 32 months (range: 0.2-75 months). At the end of the study, AZA was discontinued in 160 patients (63.2%). The main reason leading to drug withdrawal was the occurrence of AEs (109/160 patients [68.1%]; cumulative incidence among the entire cohort: 43.1%). Overall, the most frequent AEs leading to treatment withdrawal were nausea (31/253 patients, 12.3%) and subjective symptoms, i.e., poorly defined side effects such as fatigue, headache and muscle pain (20/253 patients, 7.9%). Among the 109 AZA-intolerant patients, a switch to 6-mercaptopurine (6-MP) was performed in 44 cases (40.4%). At the end of follow-up, 6-MP was discontinued in 35/44 patients (79.5%), mostly due to AEs (29/35 patients, 82.8%). Azathioprine-induced hepatic and pancreatic toxicity was associated with male gender (p = .01 and p = .03, respectively), and occurrence of nausea with Crohn's disease (p = .04). CONCLUSIONS: Our real-life prospective cohort showed the higher cumulative incidence of thiopurine withdrawal due to AEs reported to date. Switching from AZA to 6-MP was often ineffective.

Diagnostic accuracy of enhanced liver fibrosis test to assess liver fibrosis in patients with chronic hepatitis C.

BACKGROUND: The prognosis and clinical management of patients with chronic liver diseases are closely related to the severity of liver fibrosis. Liver biopsy is considered the gold standard for the staging of liver fibrosis. However, it is an invasive test sometimes related to complications. This study aimed to assess the diagnostic value of enhanced liver fibrosis (ELF) test to predict liver fibrosis in patients with chronic hepatitis C. METHODS: This study included 162 patients with liver disease and 67 healthy controls. Hyaluronic acid, tissue inhibitor of matrix metalloproteinase type 1, and amino-terminal propeptide type III procollagen were measured by enzyme-linked immunosorbent assay with the ELF test ADVIA Centaur® (Siemens Healthcare Diagnostics Inc.). Fibrosis stage was determined using the Metavir scoring system. RESULTS: In our study, for the diagnosis of significant fibrosis (Metavir F≥2) a cut-off value >7.72 provides a sensitivity of 93.0% and a specificity of 83.0%. The areas under the receiver operator characteristic curve, sensitivity, specificity, and positive and negative predictive values were 0.94, 93.3%, 81.0%, 93.3%, and 81.0%, respectively (P<0.001). For the diagnosis of cirrhosis (Metavir F=4) a cut-off value >9.3 provides a sensitivity of 93.0% and a specificity of 86.0%. The areas under the receiver operator characteristic curve, sensitivity, specificity, and positive and negative predictive values were 0.94, 79.1%, 90.8%, 75.6%, and 92.3%, respectively (P<0.001). CONCLUSIONS: The ELF test is a promising non-invasive method for assessing liver fibrosis in patients with chronic hepatitis C. It is effective in the diagnosis of both fibrosis and cirrhosis.

Testing a novel bioactive marine nutraceutical on osteoarthritis patients.

Osteoarthritis (OA) is a slow, chronic joint disease characterized by focal degeneration of articular cartilage and alterations of the chemical and mechanical articular function and also major cause of pain and physical disability. There is clinical evidence that increasing dietary n-3 relative to n-6 may be beneficial in terms of symptom management in humans but not all studies conclude that dietary n-3 PUFA supplementation is of benefit, in the treatment of OA. Our recent studies highlight the effect of a biomarine compound (LD-1227) on MMPs, collagen metabolism and on chondrocyte inflammatory markers. Thus, the aim of the present work was to test such bioactive compound versus a common nutraceutical intervention (glucosamine/chrondroitin sulfate) in knee osteoarthritis patients. The patients population consisted of 60 subjects with a recent diagnosis of knee osteoarthririts of mild-moderate severity. Patients were randomized in a double-blind study comparing LD-1227 (group A) versus a mixture of glucosamine (500 mg), chondroitin sulfate (400 mg) (group B). Patients were allowed their established painkillers on demand. At 4, 9 and 18 weeks patients were evaluated as for: VAS score assessing pain at rest, and during physical exercise, Lequesne index, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale and KOOS scale. Moreover, serum concentrations of IL-6, IL-ß, CRP, TNF-sR1 and TNF-sR2 were assessed. As compared to GC treatment, LD-1227 yielded a quicker and higher degree of improvement of the whole clinical indexes and a lower NSAIDs use at the end of the study. LD-1227 brought about also a more significant downregulation of the tested cytokines cascade. Taken overall, these data suggest that LD-1227 has the potential to be included in the nutraceutical armamentarium in the management of OA.

A sturgeon-derived bioactive compound beneficially modulates nuclear receptors controlling metabolic functions in patients with metabolic syndrome.

The aim of the present study was to test the possible effects of a novel sturgeon-derived compound  (LD-1227) on inflammatory markers related to metabolic nuclear receptors in patients with metabolic syndrome. The study population consisted of 76 patients with metabolic syndrome and 30 healthy subjects who were maintained to their current treatments and randomly supplemented: A) LD-1227 (n=38) or B) placebo (n=38) as compared to C) healthy controls (n=30). LD-1227 or placebo (water-soluble starch) were given daily at breakfast and dinner for three months. Levels of hs-CRP, IL-6, TNF-α, leptin and adiponectin/ resistin index were assayed at the entry, 1 month and 3 months afterwards. At the end of the study period, as compared to B group, LD-1227-treated patients showed a significant improvement of all parameters tested, irrespective of the presence of diabetes. In particular, levels of adiponectin and adiponectin/ resistin index significantly increased following LD-1227 administration. Although the metabolic syndrome remains a multifaceted condition requiring a complex approach, LD-1227 could be a potential safe therapeutic tool to be integrated into a wider treatment and preventive medicine schedule strategy.

The Addition of an Immunosuppressant After Loss of Response to Anti-TNFα Monotherapy in Inflammatory Bowel Disease: A 2-Year Study.

Background: The addition of an immunosuppressant (IM) after loss of response to anti-TNFα monotherapy is an emerging strategy of therapeutic optimization in patients with inflammatory bowel disease (IBD). However, few clinical data have been reported to date. We aimed to evaluate the efficacy and safety of this selective combination therapy in patients with IBD. Methods: All consecutive patients with loss of response to anti-TNFα monotherapy despite an intensive dose optimization who added an IM from October 2014 to October 2016 were entered into a prospective database. Results: Among 630 patients treated with anti-TNFα agents during the study period, 46 (7.3%) added an IM. A total of 31 patients (67.4%) were treated with an intravenous anti-TNFα (infliximab, as originator or biosimilar), while 15 (32.6%) were treated with a subcutaneous anti-TNFα agent (10 adalimumab and 5 golimumab). The mean duration of follow-up was 12.8 ± 7.3 months. Twenty-one patients (45.7%) remained on combination therapy at the end of follow-up: 15 (32.6%) maintained a steroid-free remission, and 6 (13.0%) achieved a clinical response. In patients who experienced treatment success, the median value of C-reactive protein decreased from baseline to the end of follow-up (13.2 vs 3.0, P = 0.01; normal values <5 mg/L). Adverse events leading to treatment discontinuation were reported in 8 out of 46 patients (17.4%). Conclusions: In the largest cohort on this argument reported to date, the addition of an IM was an effective and safe optimization strategy after loss of response to anti-TNFα monotherapy. Low doses of IM were sufficient to achieve a clinical response.

Mycophenolate mofetil is a valid option in patients with inflammatory bowel disease resistant to TNF-α inhibitors and conventional immunosuppressants.

BACKGROUND: Few studies investigated the role of mycophenolate mofetil in inflammatory bowel disease, and none of them had specifically focused on patients with previous multiple intolerances and/or nonresponses to conventional immunosuppressants and biologics. AIMS: To evaluate clinical benefit and tolerability profile of mycophenolate mofetil in patients with inflammatory bowel disease and limited treatment options. METHODS: All consecutive patients with previous multiple intolerances and/or nonresponses to immunosuppressants and biologics who started an off-label treatment with mycophenolate mofetil from January 2014 to February 2016 were entered in a prospectively maintained database. RESULTS: Twenty-four patients were included. Four weeks after initiation of mycophenolate mofetil therapy, a steroid-free remission was achieved in 4 patients (16.7%), while a clinical response in 13 (54.1%). At the end of follow-up, 12 patients (50.0%) remained on mycophenolate mofetil. Six achieved and maintained steroid-free remission throughout the study period (25.0%), and a further 6 patients (25.0%) achieved a clinical response with complete discontinuation of steroids. Twelve patients (50.0%) were considered as treatment failure, and five of them underwent surgery. CONCLUSIONS: This is the first experience reporting a clinical benefit and tolerability of mycophenolate mofetil in patients with inflammatory bowel disease and multiple previous failures to other immunosuppressants and/or biologics.

Gut-targeted immunonutrition boosting natural killer cell activity using Saccharomyces boulardii lysates in immuno-compromised healthy elderly subjects.

The aim of this study was to assess the immunomodulatory effect of KC-1317 (a symbiotic mixture containing Saccharomyces boulardii lysate in a cranberry, colostrum-derived lactoferrin, fragaria, and lactose mixture) supplementation in immune-compromised but otherwise healthy elderly subjects. A liquid formulation of KC-1317 was administered in a randomized controlled trial (RCT) fashion to healthy volunteers (65-79 years) previously selected for low natural killer (NK) cell activity, and this parameter was checked at the completion of the study. A significant improvement in NK cell activity of KC-1317 consumers was observed as compared to placebo at the end of 2 months. Although preliminary, these beneficial immune-modulatory effects of KC-1317 in aged individuals might indicate its employment within a wider age-management strategy.

Anti-inflammatory and anti-mutagenic effect of the YHK phytocompound in hepatocytes: in view of an age-management liver-protecting approach.

The receptor for advanced glycation end products (RAGE) regulates cellular proliferation in hepatocellular carcinoma (HCC). The aim of this study was to test the in vitro effect of Yo Jyo Hen Shi Ko (YHK), a nutraceutical with prior data suggesting its hepatocyte-protecting role, in regulating RAGE in the proliferation of the HCC cell line HuH7 as well checking also its potential modulation in the expression of the transcriptional factor nuclear factor-κB (NF-κB) p65. Our study showed that YHK significantly reduced cellular growth in the HuH7 cell line (p<0.05). Moreover, this phytocompound partly reduced gene expression of NF-κB p65 (by 35%, p<0.05). These data suggest that YHK has a potential role as a modulator of RAGE and RAGE ligands for potential healthy liver intervention in HCC prevention strategies.

The hidden phenomenon of oxidative stress during treatment of subclinical-mild hypothyroidism: a protective nutraceutical intervention.

Recent studies suggest that subjects with hypothyroidism under therapy with levothyroxine (L-T4) might develop oxidative stress. The aim of this study was to test a redox-balance modulator, fermented papaya-based nutraceutical (FPP), together with subclinical (SH) or mild hypothyroidism (MH) treatment in view of biochemical changes. A total of 60 females treated for SH-MH were divided into two matched groups and received either FPP 3 grams 1 sachet three times a day (t.i.d.) or placebo for 3 months. A significant baseline increase of all oxidative markers was observed in SH-MH (p<0.05 vs. control) and even more under T4 treatment (p<0.05). FPP caused a normalization of redox markers (p<0.01 vs. placebo). Thyroid supplementation accelerates mitochondrial oxygen consumption and oxidative stress, whereas a redox-modulator therapy is advisable, given the long-lasting treatment in such cases.
