Kassas ME, Hegazy OMO, Salah EM. Effect of treating chronic hepatitis C with direct-acting antivirals on extrahepatic cutaneous manifestations. World J Hepatol 2020; 12:841-849. [PMID: 33200021 PMCID: PMC7643207 DOI: 10.4254/wjh.v12.i10.841] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 05/25/2020] [Accepted: 09/15/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) is a disease with a significant global impact, affecting approximately 2%-2.5% of the world’s population. New direct-acting antivirals (DAAs) have been introduced over the past few years with great success in viral eradication. The association of chronic HCV infection with a wide spectrum of cutaneous manifestations has been widely reported in the literature.
AIM To assess the effect of treating HCV with DAAs on the extrahepatic cutaneous manifestations of HCV.
METHODS This prospective observational study included 1039 HCV positive Egyptian patients who were eligible to receive DAAs. A total of 30 patients were diagnosed with extrahepatic cutaneous manifestations and fulfilled the inclusion criteria of the study. Of these patients, 6 had classic lichen planus, 8 were diagnosed with psoriasis vulgaris and 16 had pruritus. All patients received DAAs from October 2018 to July 2019 in the form of a three-month course of sofosbuvir/daclatasvir combination. Patients with lichen planus or psoriasis were dermoscopically evaluated before treatment and 6 mo after treatment, while patients with hepatic pruritus were assessed using the 12-Item Pruritus Severity Scale over the same period.
RESULTS All patients with psoriasis showed significant improvement in all psoriatic plaques, and all patients with hepatic pruritus scored 0 on the 12-Item Pruritus Severity Scale indicating total improvement of pruritus. In addition, four of six patients with lichen planus showed complete improvement.
CONCLUSION Treatment of HCV with DAAs was significantly effective in improving virus-related extrahepatic cutaneous manifestations.

Abstract
Chronic hepatitis C virus (HCV) infection has been associated with both organ-specific and systemic autoimmune diseases, with cryoglobulinemia being the most frequent associated disease. Experimental, virologic, and clinical evidence have demon-strated a close association between HCV infection and some systemic autoimmune diseases, especially Sjögren's syndrome, but also rheumatoid arthritis and lupus. A higher prevalence of hematological processes has also been described in patients with HCV infection, including cytopenias and lymphoproliferative disorders (B-cell lymphoma). In addition, patients with chronic HCV infection have a higher frequency of other extrahepatic manifestations including endocrine, metabolic and cardiovascular disorders that may worse the prognosis of patients, along with neuropsychiatric manifestations and general symptoms that have a significant influence on the quality of life of the patient. Direct-acting antiviral therapies (DAAs) that have recently begun to be used are providing the opportunity to effectively cure chronic HCV infection and reduce the burden of both hepatic and extrahepatic complications.

Abstract
BACKGROUND The current study aimed at testing the effect of corticosteroid therapy on serum levels of interleukin-10 (IL-10) and IL-17 as well as lncRNA-AF085935 in patients of rheumatoid arthritis (RA) associated with hepatitis C virus (HCV) and evaluating the usefulness of using these parameters to predict the therapeutic efficacy of steroids in these patients. METHODS Thirty healthy control subjects and 65 chronic HCV patients with RA were included in our study. Patients were subjected to clinical examination, abdominal ultrasound, and liver biopsy and received 6-methyl-prednisolone (PDN) 16 mg/day for 48 weeks. Blood samples were collected from all subjects and serum was separated to assess IL-10 and IL-17 by ELISA and HCV RNA and lncRNA-AF085935 by qRT-PCR. RESULTS Our study revealed that there were significant increases in serum levels of IL-10, IL-17 and lncRNA-AF085935 in RA patients associated with HCV compared with healthy control subjects. Also there were significant increases in serum levels of IL-10 and HCV RNA and a significant decrease in serum level of IL-17 in patients after corticosteroid therapy, while lncRNA-AF085935 is not significantly changed. CONCLUSION LncRNA-AF085935 might be a useful candidate biomarker for the early detection of RA associated with HCV, providing potential new strategies for early screening and therapy of these patients. IL-17 is a non-invasive prognostic marker to predict the efficacy of corticosteroid therapy in RA patients associated with chronic hepatitis C.

How hepatitis C virus modifies the immunological profile of Sjögren syndrome: analysis of 783 patients. Arthritis Res Ther 2015; 17:250. [PMID: 26370711 PMCID: PMC4570241 DOI: 10.1186/s13075-015-0766-3] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2015] [Accepted: 08/24/2015] [Indexed: 12/27/2022] Open
Abstract
INTRODUCTION We conducted a study to analyze how infection by hepatitis C virus (HCV) may influence the immunological serum pattern of patients with Sjögren syndrome (SS). METHODS Since 1994, we have tested serum HCV-IgG antibodies in 783 patients with SS diagnosed according to the 1993 European classification criteria. The immunological profile at diagnosis was compared according to the presence or absence of HCV. RESULTS Of the 783 patients with SS, 105 (13.4 %) tested positive for HCV-IgG antibodies (88 females, 17 males, mean age at SS diagnosis: 62.9 years). Multivariate analysis showed that patients with SS-HCV had a higher mean age and a higher frequency of low C3/C4 levels, cryoglobulins, and hematological neoplasia compared with patients without HCV. The frequency of anti-La antibodies compared with anti-Ro antibodies was higher in patients with SS-HCV (17 % vs. 15 %) and lower in patients without HCV infection (30 % vs. 43 %). The frequency of concomitant detection of the three main cryoglobulin-related markers (cryoglobulins, rheumatoid factor activity, and C4 consumption) was threefold higher in patients with SS-HCV compared with patients without HCV. SS-HCV patients with genotype 1b showed the highest frequencies of immunological abnormalities related to cryoglobulins and the lowest frequencies of anti-Ro/La antibodies. CONCLUSIONS We found HCV infection in 13 % of a large series of Spanish patients with SS. The HCV-driven autoimmune response was characterized by a lower frequency of anti-Ro/La antibodies, an abnormal predominance of anti-La among anti-Ro antibodies, and a higher frequency of cryoglobulinemic-related immunological markers in comparison with patients without HCV infection. This immunological pattern may contribute to the poor outcomes found in patients with SS-HCV.

Abstract
Hepatitis C virus (HCV) affects millions of people worldwide, and an estimated 3.2 million people in the United States. HCV is a hepatotropic and lymphotropic virus that causes not only liver disease, but also a significant number of extrahepatic manifestations (EHMs). Up to 74% of patients affected by HCV will have HCV-related EHMs of some severity in their lifetime. The EHMs vary from simple cutaneous palpable purpura to complex lymphoproliferative disorders, including lymphomas and immune-complex deposit diseases causing local and/or systemic complications. Mixed cryoglobulinemia (MC) is manifested by multiple systemic organ involvement, mainly skin, kidney, peripheral nerves, and salivary glands, and less frequently causes widespread vasculitis and malignant lymphoma. MC affects up to 3% of HCV-infected patients with cryoglobulinemia of clinical significance, i.e. >6%. Severe disease requires immunosuppressive or plasma exchange therapy. HCV prevalence in the United States in patients with porphyria cutanea tarda (PCT) was reported to be 66%, much higher than that in general population. Therefore, all patients with PCT should be screened for HCV. The skin rash of PCT varies from large blisters to small vesicles and/or milia on the hands. Skin manifestations due to PCT usually respond to anti-HCV treatment together with reducing skin sun exposure, avoiding triggers, having routine phlebotomy (especially for people with chronic iron overload states), and using chloroquine. Lichen planus (LP), which typically affects both the skin and oral mucosa is a chronic inflammatory disease of squamous cell origin affecting about 1% of the worldwide population. The prevalence of HCV in patients with LP varies based on geographic location. We review here the basic pathophysiology, clinical features, and management of dermatologic manifestations of HCV.

Abstract
OBJECTIVE The purpose of this study was to evaluate whether individuals consider their HCV infection to be a potentially traumatic experience. Additionally, we investigated its association with Post-Traumatic Stress Disorder (PTSD) and the impact of PTSD diagnosis on health-related quality of life (HRQoL) in HCV infected subjects. METHODS We conducted a cross-sectional survey of 127 HCV-infected outpatients recruited at a University Hospital in Salvador, Brazil. All subjects answered an orally-administered questionnaire to gather clinical and socio-demographic data. We investigated traumatic experiences and the subject's perception of the disease using the Trauma History Questionnaire. PTSD and other psychiatric diagnoses were assessed through the Mini International Neuropsychiatric Interview-Brazilian Version 5.0.0 (M.I.N.I. PLUS). HRQoL was assessed using Short-Form 36 (SF-36). RESULTS Approximately 38.6% of the patients considered hepatitis C to be a traumatic experience. Of these, 60.7% had a PTSD diagnosis. PTSD was associated with significant impairment in quality of life for individuals in seven SF-36 domains as shown bymultivariate analysis: Role-Physical (β: -24.85; 95% CI: -42.08; -7.61), Bodily Pain (β: -19.36; 95% CI: -31.28; -7.45), General Health (β: -20.79; 95% CI: -29.65; -11.92), Vitality (β: -11.92; 95% CI: -20.74; -3.1), Social Functioning (β: -34.73; 95% CI: -46.79; -22.68), Role-Emotional (β: -26.07; 95% CI: -44.61; -7.53), Mental Health (β: -17.46; 95% CI: -24.38; -10.54). CONCLUSION HCV is frequently a traumatic experience and it is strongly associated with PTSD diagnosis. PTSD significantly impaired HRQoL.

Abstract
Cryoglobulinemia is characterized by a wide range of causes, symptoms, and outcomes. Hepatitis C virus (HCV) infection is detected in 30%-100% of patients with cryoglobulins. Although more than half the patients with cryoglobulinemic vasculitis present a relatively benign clinical course, some may present with potentially life-threatening situations. We conducted the current study to analyze the clinical characteristics and outcomes of HCV patients presenting with life-threatening cryoglobulinemic vasculitis. We evaluated 181 admissions from 89 HCV patients diagnosed with cryoglobulinemic vasculitis consecutively admitted to our department between 1995 and 2010. In addition, we performed a systematic analysis of cases reported to date through a MEDLINE search.The following organ involvements were considered to be potentially life-threatening in HCV patients with cryoglobulinemic vasculitis: cryoglobulinemic, biopsy-proven glomerulonephritis presenting with renal failure; gastrointestinal vasculitis; pulmonary hemorrhage; central nervous system (CNS) involvement; and myocardial involvement. A total of 279 patients (30 from our department and 249 from the literature search) fulfilled the inclusion criteria: 205 presented with renal failure, 45 with gastrointestinal vasculitis, 38 with CNS involvement, 18 with pulmonary hemorrhage, and 3 with myocardial involvement; 30 patients presented with more than 1 life-threatening cryoglobulinemic manifestation. There were 146 (52%) women and 133 (48%) men, with a mean age at diagnosis of cryoglobulinemia of 54 years (range, 25-87 yr) and a mean age at life-threatening involvement of 55 years (range, 25-87 yr). In 232 (83%) patients, life-threatening involvement was the first clinical manifestation of cryoglobulinemia. Severe involvement appeared a mean of 1.2 years (range, 1-11 yr) after the diagnosis of cryoglobulinemic vasculitis. Patients were followed for a mean of 14 months (range, 3-120 mo) after the diagnosis of life-threatening cryoglobulinemia. Sixty-three patients (22%) died. The main cause of death was sepsis (42%) in patients with glomerulonephritis, and cryoglobulinemic vasculitis itself in patients with gastrointestinal, pulmonary, and CNS involvement (60%, 57%, and 62%, respectively). In conclusion, HCV-related cryoglobulinemia may result in progressive (renal involvement) or acute (pulmonary hemorrhage, gastrointestinal ischemia, CNS involvement) life-threatening organ damage. The mortality rate of these manifestations ranges between 20% and 80%. Unfortunately, this may be the first cryoglobulinemic involvement in almost two-thirds of cases, highlighting the complex management and very elevated mortality of these cases.

Abstract
PURPOSE OF REVIEW To summarize the recent developments concerning the potential viral pathomechanisms and involvement of viruses in Sjögren's syndrome, and to highlight the areas for future research and therapies. RECENT FINDINGS Activated IFN-1 pathway plays an important part in the autoimmune disease process of Sjögren's syndrome; therefore, several therapies aiming to reduce or inhibit the IFN-1 production and its effects may be a target for future treatment plans. Activated aryl hydrocarbon receptor may interact with latent Epstein-Barr virus (EBV) infection, which in turn may predispose to the development of Sjögren's syndrome. It is estimated that the population is 95% positive for EBV serology. Microbial factors may incite autoimmune disease. Although this hypothesis is proven in a few illnesses such as rheumatic fever, there is no definitive evidence of an infectious environmental trigger in Sjögren's syndrome. However, there are circumstantial data with regard to viruses and several potential mechanisms of disease. These include antigen mimicry, polyclonal lymphocyte activation, and infection-mediated innate end-organ inflammation. In addition, hepatitis C virus infection clearly causes a Sjögren's-syndrome-like illness. SUMMARY Data continue to implicate viral infection in the cause of Sjögren's syndrome, but there are no definitive studies incriminating a particular virus.

Abstract
Background Both type I interferon (IFN), also known as IFN-α and tumor necrosis factor alpha (TNF-α) have been implicated in the pathogenesis of sarcoidosis. We investigated serum levels of these cytokines in a large multi-ancestral sarcoidosis population to determine correlations between cytokine levels and disease phenotypes. Methods We studied serum samples from 98 patients with sarcoidosis, including 71 patients of African-American ancestry and 27 patients of European-American ancestry. Serum type I IFN was measured using a sensitive reporter cell assay and serum TNF-α was measured using a commercial ELISA kit. Clinical data including presence or absence of neurologic, cardiac, and severe pulmonary manifestations of sarcoidosis were abstracted from medical records. Twenty age-matched non-autoimmune controls were also studied from each ancestral background. Differences in cytokine levels between groups were analyzed with Mann-Whitney U test, and correlations were assessed using Spearman's rho. Multivariate logistic regression models were used to detect associations between cytokines and clinical manifestations. Results Significant differences in cytokine levels were observed between African- and European-American patients with sarcoidosis. In African-Americans, serum TNF-α levels were significantly higher relative to matched controls (P = 0.039), and patients with neurologic disease had significantly higher TNF-α than patients lacking this manifestation (P = 0.022). In European-Americans, serum type I IFN activity was higher in sarcoidosis cases as compared to matched controls, and patients with extra-pulmonary disease represented a high serum IFN subgroup (P = 0.0032). None of the associations observed were shared between the two ancestral groups. Conclusions Our data indicate that significant associations between serum levels of TNF-α and type I IFN and clinical manifestations exist in a sarcoidosis cohort that differ significantly by self-reported ancestry. In each ancestral background, the cytokine elevated in patients with sarcoidosis was also associated with a particular disease phenotype. These findings may relate to ancestral differences in the molecular pathogenesis of this heterogeneous disease.

Abstract
A clinical picture of dry eye and dry mouth with the histological counterpart of focal lymphocytic sialoadenitis, usually detected in minor salivary glands, is considered the hallmark of Sjögren's syndrome. The association of sicca complaints and focal sialoadenitis can be also found in a number of other diseases, including some systemic viral infections. Among these conditions, chronic hepatitis C virus infection, associated with mixed cryoglobulinaemia and extra-hepatic manifestations, and HIV infection, particularly in the phase of diffuse interstitial lymphocytic infiltration, may mimic the clinical and histological aspects of Sjögren's syndrome. However, each disorder is characterised by specific, disease-related immunopathological aspects. Besides sicca complaints, the various disorders may also share a number of systemic extra-glandular features and the possible development of mucosa-associated lymphoid tissue lymphomas. This latter event represents in all of these diseases the final result of an antigen-driven chronic stimulation of B lymphocytes.

Abstract
Sarcoidosis is a systemic inflammatory disease of an unknown origin and it is characterized by the presence of noncaseating epitheloid cell granulomas in multiple organs. Herein we report on a case of cutaneous and pulmonary sarcoidosis that was associated with interferon alpha treatment for hepatitis C. A 39-year-old man, a former intravenous drug user, presented with several erythematous papules on both antecubital areas. The histopathologic finding of a skin biopsy showed noncaseating granuloma. The mediastinal and axillary lymph nodes were enlarged on chest X-ray and computed tomography. To the best of our knowledge, this is the first report of cutaneous and pulmonary sarcoidosis that was associated with interferon treatment in the Korean dermatologic literature.

Abstract
OBJECTIVE To describe the clinical and immunologic characteristics of a large series of patients with systemic autoimmune diseases (SAD) associated with chronic hepatitis C virus (HCV) infection. METHODS The HISPAMEC Registry is a multicenter international study group dedicated to collecting data on patients diagnosed with SAD with serological evidence of chronic HCV infection. The information sources are cases reported by physicians of the HISPAMEC Study Group and periodic surveillance of reported cases by a Medline search updated up to December 31, 2007. RESULTS One thousand twenty HCV patients with SAD were included in the registry. Patients were reported from Southern Europe (60%), North America (15%), Asia (14%), Northern Europe (9%), South America (1%), and Australia (1%). Countries reporting the most cases were Spain (236 cases), France (222 cases), Italy (144 cases), USA (120 cases), and Japan (95 cases). The most frequently reported SAD were Sjögren's syndrome (SS; 483 cases), rheumatoid arthritis (RA; 150 cases), systemic lupus erythematosus (SLE; 129 cases), polyarteritis nodosa (78 cases), antiphospholipid syndrome (59 cases), inflammatory myopathies (39 cases), and sarcoidosis (28 cases). Twenty patients had 2 or more SAD. Epidemiological data were available in 677 cases. Four hundred eighty-seven (72%) patients were female and 186 (28%) male, with a mean age of 49.5 +/- 1.0 years at SAD diagnosis and 50.5 +/- 1.1 years at diagnosis of HCV infection. The main immunologic features were antinuclear antibody (ANA) in 61% of patients, rheumatoid factor (RF) in 57%, hypocomplementemia in 52%, and cryoglobulins in 52%. The main differential aspect between primary and HCV-related SAD was the predominance of cryoglobulinemic-related markers (cryoglobulins, RF, hypocomplementemia) over specific SAD-related markers (anti-ENA antibodies, anti-dsDNA, anti-cyclic citrullinated peptide) in patients with HCV. CONCLUSION In the selected cohort, the SAD most commonly reported in association with chronic HCV infection were SS (nearly half the cases), RA and SLE. Nearly two thirds of SAD-HCV cases were reported from the Mediterranean area. In these patients, ANA, RF and cryoglobulins are the predominant immunological features.

Abstract
Hepatitis C virus (HCV) infection is frequently associated with anti-SSA/Ro and anti-SSB/La autoantibodies. The objective of this study is to examine the prevalence of anti-SSA/Ro and anti-SSB/La autoantibodies in HCV-infected patients and their possible associations with HLA-DRB1 polymorphism in Chinese patients in Taiwan. About 288 HCV-infected patients were recruited for autoantibody detection and HLA-DRB1 typing. Anti-SSA/Ro and anti-SSB/La autoantibodies were detected in 12.8 and 9.7% of HCV-infected patients. Anti-SSA/Ro antibody was positively associated with age over 55 [p = 0.04; odds ratio = 2.17; 95% confidence interval (CI), 1.03-4.57]. Anti-SSB/La antibody was negatively associated with HLA-DR2 carriage (p = 0.024; odds ratio = 0.30; 95% CI, 0.10-0.90). No significant correlation was found between autoantibody production and gender, autoimmune manifestation, presence of cirrhosis, or hepatocellular carcinoma in HCV infection. In conclusion, anti-SSA/Ro and anti-SSB/La antibodies present frequently in HCV-infected patients. Anti-SSB/La antibody is negatively associated with HLA-DR2 in HCV-infected patients in Taiwan.

Abstract
Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly affects the exocrine glands and usually presents as persistent dryness of the mouth and eyes because of functional impairment of the salivary and lacrimal glands. The histological hallmark is a focal lymphocytic infiltration of the exocrine glands, and the spectrum of the disease extends from an organ-specific autoimmune disease (autoimmune exocrinopathy) to a systemic process with diverse extraglandular manifestations. In the absence of an associated systemic autoimmune disease, patients with this condition are classified as having primary SS. The differential diagnosis includes processes that specifically involve the exocrine glands. On the one hand, some chronic viral infections may induce lymphocytic infiltration of the exocrine glands, in some cases indistinguishable from that observed in primary SS. On the other hand, some processes may mimic the clinical picture of SS through nonlymphocytic infiltration of the exocrine glands. This review focuses on these two groups of diseases that mimic SS (infections and infiltrating processes).

Abstract
To determine whether the clinical and immunological expression of patients with cryoglobulinaemia associated with chronic hepatitis C virus (HCV) infection varied according to HCV-RNA load, HCV genotype or human immunodeficiency virus (HIV) coinfection. We studied 340 HCV patients (188 women and 152 men, with a mean age of 49 years) consecutively diagnosed with cryoglobulinaemia between 1993 and 2003 in our hospital. HCV infection was confirmed by serum HCV-RNA determination in all patients. Two hundred and forty-eight (73%) patients had asymptomatic cryoglobulinaemia and 92 (27%) presented cryoglobulinaemic symptoms. Patients with genotype 1 had a higher mean age at diagnosis of cryoglobulinaemia (48.2 vs 40.2 yrs, P < 0.001) and a higher prevalence of cryoglobulinaemic symptoms (25%vs 10%, P = 0.02), especially of vasculitic features (19%vs 5%, P = 0.014). In comparison with monoinfected HCV patients, those with HIV coinfection had a lower mean age at diagnosis of cryoglobulinaemia (40.4 vs 52.8 years, P < 0.001), a lower prevalence of cryoglobulinaemic symptoms (15%vs 34%, P < 0.001), vasculitis (10%vs 28%, P < 0.001), associated systemic autoimmune disease (3%vs 14%, P = 0.001), rheumatoid factor (30%vs 70%, P = 0.001) and hypocomplementaemia (50%vs 78%, P = 0.01). In HCV-HIV patients, a high viral load was associated with a high frequency of symptomatic cryoglobulinaemia, especially in patients with a high viral load of the two viruses (50%vs 7%, P = 0.001) A higher frequency of cryoglobulinaemic symptoms (especially vasculitis) was found in patients with HCV monoinfection and in those carrying HCV genotype 1. In contrast, patients with HIV coinfection presented a threefold lower prevalence of vasculitis. Associated HIV infection significantly attenuated the clinical and immunological expression of cryoglobulinaemia, except in coinfected patients with high viral loads for the two viruses.

Abstract
Dr. Josep Font (Barcelona, 1953-2006) devoted his professional career to the care of patients with systemic autoimmune diseases (SAD). In 1995, he created the Department of Autoimmune Diseases at the Hospital Clinic in Barcelona, a pioneering unit in Europe specifically dedicated to the clinical management of these patients. The research output of Dr. Font has been prodigious, with a total of over 500 scientific articles published in 25 years, and was especially focused on the clinical and immunological characterization of systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (SS). This review briefly analyzes some of the main contributions of Josep Font to our current knowledge about these diseases. In SLE, the research was centered on the epidemiological and clinical characterization, the study of cardiovascular and vasculitic involvements, and the investigation of the etiopathogenic role of the innate immunity. In primary SS, basic research conducted by Dr. Font contributed to a better understanding of the autoimmune etiopathogenesis of the disease, while the clinical research expanded our knowledge about the systemic and immunological expression of the disease and its frequent association with lymphoma, other SAD, and chronic viral infections.
