Presence of Serum Antinuclear Antibodies Does Not Impact Long-Term Outcomes in Nonalcoholic Fatty Liver Disease
2020
Introduction We investigated the longitudinal impact of antinuclear antibody (ANA) on clinical outcomes and survival in nonalcoholic fatty liver disease (NAFLD). Methods ANA were found in 16.9% of 923 biopsy-proven NAFLD patients, but none of them had histologic autoimmune hepatitis (AIH) or developed AIH after a mean follow-up of 106±50 months. Results Although ANA-positive cases had a higher prevalence of nonalcoholic steatohepatitis at baseline, the occurrence of liver-related events, hepatocellula carcinoma, cardiovascular events, extrahepatic malignancy, and overall survival were similar to ANA-negative. Discussion Once AIH has been ruled out, the long-term outcomes and survival are un…
A real life comparison of the effectiveness of adalimumab and golimumab in moderate-to-severe ulcerative colitis, supported by propensity score analy…
2018
Abstract Background Adalimumab and golimumab are effective in the treatment of moderate to severe ulcerative colitis. Aims We reported the comparative effectiveness of adalimumab and golimumab in ulcerative colitis. Methods 118 patients treated with adalimumab and 79 treated with golimumab were included and evaluated at 8 weeks and at the end of follow up. Results Overall clinical benefit was 72.6% at 8 weeks and 58.9% at the end of follow up. Patients with longer disease duration and those treated with adalimumab had a better outcome. Clinical benefit was 78.8% in adalimumab patients and 63.3% in golimumab patients (p = 0.026) after 8 weeks; it was 66.9% in adalimumab patients and 46.8% in…
Trastuzumab-emtansine induced pleural and pericardial effusions
2021
Introduction Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate which combine trastuzumab (T), a monoclonal antibody targeting the human epidermal growth factor receptor-2 (HER2), and a cytotoxic molecule derived from maytansine (DM1). Case report We report the first case of T-DM1-associated pleural and pericardial effusions three weeks after the second course of T-DM1 in a patient with breast cancer. Drug-induced pleural and pericardial effusions was implicated in the absence of other etiologies. The Naranjo Scale indicated a probable drug-induced adverse reaction. Management & outcome: The patient fully recovered after thoracentesis and discontinuation of T-DM1. The patient h…
The challenge of using the rheumatoid arthritis diagnostic criteria in clinical practice.
2015
The new 2010 ACR/EULAR (American College of Rheumatology/European League Against Rheumatism) criteria of Rheumatoid Arthritis recently published, have been released to classify and identify patients with early RA who could benefit from early therapy. They recommend anti-citrullinated protein antibody (ACPA) testing as an alternative criterion to Rheumatoid Factor (RF) and ACPA that were introduced together with the other classic criteria in a scoring system. We previously criticized these new criteria because of unavailable specificity and sensibility in the first paper, and the use of ACPA as dichotomous criterion (presence/absent) and alternatives to rheumatoid factor. Our previous work p…
MINIMIZING INFLIXIMAB TOXICITY IN THE TREATMENT OF INFLAMMATORY BOWEL DISEASE
2008
Abstract Background Infliximab is a widely used biological agent for the treatment of inflammatory bowel disease, and has a favorable risk/benefit ratio. Aim It is useful to know that patients treated with infliximab are exposed to developing adverse events that could be reduced with a prudent and a rational clinical approach and by optimizing the treatment protocol. Methods PubMed (including Epub) was searched in October 2006 and again in March 2007. Results The high immunogenic potential of infliximab determines the antibodies that inhibit the effect of infliximab and the appearance of subsequent acute and delayed infusion reactions. Infliximab has an immunomodulatory effect, thus increas…
Early Treatment of Systemic Juvenile Idiopathic Arthritis with Canakinumab and Complete Remission After 2 Years of Treatment Suspension: Case Report …
2019
Systemic juvenile idiopathic arthritis (sJIA) is an autoinflammatory disease characterised by fever and arthritis. We describe the case of a 14-year-old girl hospitalised with fever associated with rash, myalgia, arthralgia and polyarticular involvement. Examinations revealed increased levels of C-reactive protein, erythrocyte sedimentation rate, ferritin, triglycerides, leukocytes, neutrophils, lactate dehydrogenase, fibrinogen, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT). Bone marrow biopsy showed polyclonal leukocyte activation. A genetic study revealed a heterozygous mutation of the MEFV gene, c.442G>C (E148Q), which is typical of…
Immune-mediated rippling muscle disease with myasthenia gravis: a report of seven patients with long-term follow-up in two.
2009
We report seven patients with immune-mediated rippling muscle disease (iRMD) and AChR-antibody positive myasthenia gravis (MG) without germline caveolin-3 gene mutations. We describe the follow-up of two patients and the clinical features of five new patients (1 female, 4 male, aged 32 to 69 years). These presented with significant generalized, exercise-induced and electrically-silent muscle rippling with myalgia, combined with generalized MG. In two of the seven patients, MG appeared before iRMD. Mediastinal imaging excluded thymic alterations in all, although two had other coincident tumours. Myalgia and rippling were aggravated by acetylcholinesterase-inhibitor treatment. Generalized MG …
Metalloproteinases and Tissue Inhibitors in Generalized Myasthenia Gravis. A Preliminary Study
2022
Introduction: Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) have recently been proposed as promising biomarkers in different immune-mediated disorders. We evaluated the plasma levels of MMP-9 and MMP-2 and their tissue inhibitors TIMP-1 and TIMP-2 in a patients’ cohort with generalized myasthenia gravis (MG). Methods: Plasma concentrations of MMP-9, MMP-2, TIMP-1 and TIMP-2 were evaluated in 14 patients with generalized MG and 13 age- and sex-matched healthy controls. The severity of disease was assessed by the modified Osserman classification. Results: Compared to the healthy subjects, MG patients had increased plasma concentrations of MMP-9, but redu…
Pathogenesis and autoimmunity initiated by a viral protein-induced apoptotic bodies
2016
Ihmisen parvovirus B19 (B19) on laajalle levinnyt, yleinen virus, joka aiheuttaa lapsissa parvorokkoa (viides tauti). Aikuisille B19 aiheuttaa erinäisiä sairauksia, muun muassa nivelkipuja ja – tulehdusta, anemiaa, sekä raskaana oleville sikiöpöhöä. Lisäksi B19 infektio saattaa johtaa autoimmuunisairauksiin, kuten punahukkaan (systemic lupus erythematosus, SLE), nivelreumaan ja sydänlihastulehdukseen. Toisaalta infektio voi olla myös täysin oireeton. Mekanismit, jotka johtavat B19 tartunnasta autoimmuunisairauteen, ovat vielä tuntemattomia. Kuitenkin tiedetään, että B19:n ei-rakenteellinen proteiini NS1 on soluille tuhoisa ja aiheuttaa niiden kuoleman (apoptoosin) muodostaen solunjäännösten…
Lack of reactivation of tuberculosis in patients with psoriasis treated with secukinumab in a real-world setting of latent tuberculosis infection
2022
Background Some biologics for psoriasis, especially anti-tumor necrosis factor (TNF)-alpha therapies, may re-activate latent tuberculosis (TBC) infection with consequent morbidity and mortality. However, there is a low reported incidence of conversion to positive TBC status among patients with psoriasis treated with second-generation biologic therapies, particularly anti-interleukin (IL)-17 therapies such as secukinumab. Objectives To evaluate the safety profile of secukinumab in psoriasis patients with latent TBC infection. Methods Real-life data were collected by retrospective chart review on patients with moderate-to-severe psoriasis who showed positivity for TBC screening at baseline an…
