Monoclonal Antibodies in the Management of Inflammation in Wound Healing: An Updated Literature Review. J Clin Med 2024; 13:4089. [PMID: 39064129 PMCID: PMC11278249 DOI: 10.3390/jcm13144089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 07/01/2024] [Accepted: 07/03/2024] [Indexed: 07/28/2024] Open
Abstract
Chronic wounds pose a significant clinical challenge due to their complex pathophysiology and the burden of long-term management. Monoclonal antibodies (mAbs) are emerging as a novel therapeutic option in managing difficult wounds, although comprehensive data on their use in wound care are lacking. This study aimed to explore existing scientific knowledge of mAbs in treating chronic wounds based on a rationale of direct inhibition of the main molecules involved in the underlying inflammatory pathophysiology. We performed a literature review excluding primary inflammatory conditions with potential ulcerative outcomes (e.g., hidradenitis suppurativa). mAbs were effective in treating wounds from 16 different etiologies. The most commonly treated conditions were pyoderma gangrenosum (treated with 12 different mAbs), lipoid necrobiosis, and cutaneous vasculitis (each treated with 3 different mAbs). Fourteen mAbs were analyzed in total. Rituximab was effective in 43.75% of cases (7/16 diseases), followed by tocilizumab (25%, 4/16 diseases), and both etanercept and adalimumab (18.75%, 3/16 conditions each). mAbs offer therapeutic potential for chronic wounds unresponsive to standard treatments. However, due to the complex molecular nature of wound healing, no single target molecule can be identified. Therefore, the use of mAbs should be considered as a translational approach for limited cases of multi-resistant conditions.

HCV Genotype Has No Influence on the Incidence of Diabetes-EpiTer Multicentre Study. J Clin Med 2022; 11:jcm11020379.

Abstract
HCV infection is one of the main reasons for liver cirrhosis and hepatocellular carcinoma. In recent years, one finds more and more extrahepatic manifestations of HCV infection, including its possible influence on the development of diabetes. In the presented work, one finds the frequency analysis of the incidence of diabetes among 2898 HCV infected patients treated in Poland, and the assessment of their relevance to the HCV genotype and the progression of fibrosis. The results indicate that the hepatitis C infection seems to be a risk factor for diabetes in persons with more advanced liver fibrosis, for older people, and for the male gender. Thus, one found no differences regarding the frequency of its incidence depending on HCV genotype, including genotype 3.

Abstract
Sclerodermalike syndromes (SLSs) comprise diseases with mucin deposition (eg, scleromyxedema, scleredema), with eosinophilia (eg, eosinophilic fasciitis), metabolic or biochemical abnormalities (eg, nephrogenic systemic fibrosis), or endocrine disorders (eg, POEMS syndrome, or polyneuropathy, organomegaly, endocrinopathy, monoclonal lymphoproliferative disorder, and hypothyroidism). Chronic graft-versus-host disease may also show sclerodermalike skin changes. Inherited progeria syndromes with early aging (eg, Werner syndrome) and a heterogeneous group of hereditary disorders with either skin thickening (eg, stiff skin syndrome) or atrophy and tightening (eg, acrogeria) can also imitate classic systemic sclerosis (SSc). In addition, SLSs can be provoked by several drugs, chemicals, or even physical injury (eg, trauma, vibration stress, radiation). In SLSs, the distribution of skin involvement seems to be atypical compared with SSc. The acral skin involvement is usually missing, and lack of Raynaud phenomenon, scleroderma-specific antinuclear antibodies, the absence of scleroderma capillary pattern, and internal organ manifestations indicate the presence of an SLS. Skin involvement is sometimes nodular, and the underlying tissues can also be affected. For the differential diagnosis, a skin biopsy of the deeper layers including fascia and muscle is required. Histology does not always allow differentiation between SSc and SLSs; therefore, the diagnosis is often based on the distribution, quality of cutaneous involvement, and other accompanying clinical features.

Abstract
Chronic hepatitis C virus (HCV) infection is one of the major causes of death worldwide due to infectious agents. The advent of direct-acting antivirals has dramatically improved the chance of HCV elimination, even for patients with decompensated cirrhosis. Along with HCV cure, benefits are recognized in terms of regression of liver fibrosis and risk of hepatocellular carcinoma. Furthermore, beyond hepatic outcomes, several extrahepatic benefits may result from sustained HCV eradication, including improvements in the neurocognitive function and reduced cardiovascular disease risk. Finally, there is no doubt that the individual success of direct-acting antivirals is largely contributing to halt HCV transmission globally, in the absence of an effective HCV prophylactic vaccine.

Abstract
Hepatitis C virus (HCV) is a major cause of liver diseases including liver cirrhosis and hepatocellular carcinoma. Approximately 3% of the world population is infected with HCV. Thus, HCV infection is considered a public healthy challenge. It is worth mentioning, that the HCV prevalence is dependent on the countries with infection rates around 20% in high endemic countries. The review summarizes recent data on HCV molecular biology, the physiopathology of infection (immune-mediated liver damage, liver fibrosis and lipid metabolism), virus diagnostic and treatment. In addition, currently available in vitro, ex vivo and animal models to study the virus life cycle, virus pathogenesis and therapy are described. Understanding of both host and viral factors may in the future lead to creation of new approaches in generation of an efficient therapeutic vaccine.

Abstract
Besides liver cirrhosis and hepatocellular carcinoma, chronic hepatitis C virus (HCV) infection is associated with many extrahepatic manifestations (EHMs). HCV exhibits lymphotropism that is responsible for various EHM. An important characteristic of HCV is escape from the immune system, which enables it to produce chronic infections and autoimmune disorders along with accumulation of circulating immune complexes. These EHMs have large spectrum, because they affect many organs such as heart, lungs, kidney, brain, thyroid, and skin. HCV-related cardiac and pulmonary manifestations include myocarditis, cardiomyopathies, cardiovascular diseases (i.e., Stroke, ischemic heart disease), chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, asthma, and interstitial lung diseases. This review discusses etiology and pathogenesis of HCV-associated cardiac and pulmonary manifestations and how different genes, immune system, indirectly linked factors (mixed cryoglobulinemia), liver cirrhosis, and antiviral treatment are involved in HCV-related heart and lung diseases, however, their exact mechanism is not clear.

Abstract
Parkinson's disease (PD) is a globally prevalent neurodegenerative disorder, characterized by progressive neuronal loss in the substantia nigra and formation of Lewy bodies. These pathological characteristics are clinically translated into motor symptoms, such as bradykinesia, rigidity, resting tremors, and postural instability. Emerging data from epidemiological studies suggest a possible association between PD and hepatitis C virus (HCV) infection, which affects up to 71 million individuals worldwide. Preclinical studies have shown that HCV can penetrate and replicate within the brain macrophages and microglial cells, increasing their production of pro-inflammatory cytokines that can directly cause neuronal toxicity. Other studies reported that interferon, previously used to treat HCV infection, can increase the risk of PD through inhibition of the nigrostriatal dopaminergic transmission or induction of neuroinflammation. In this article, we provide a comprehensive review on the possible association between HCV infection and PD and highlight recommendations for further research and practice in this regard.

Abstract
Chronic hepatitis C virus (HCV) infection is associated with various extrahepatic manifestations, including dermatologic involvement mostly caused by immune complexes. Mixed cryoglobulinemia has a strong relationship with HCV with 95% of these patients being infected with HCV. Lichen planus is a disease of the squamous epithelium and may affect any part of the skin, with 4% to 24% of patients with lichen planus reported to have chronic HCV infection. Porphyria cutanea tarda is the most common form of porphyria, and it is thought that HCV interferes with iron stores, which can promote porphyria cutanea tarda. Finally, necrolytic acral erythema is a rare, psoriasis-like disease closely associated with HCV.

Abstract
A symptomatic joint involvement and arthralgia are frequent in patients with chronic hepatitis C virus (HCV) infection. However, HCV infection-related arthritis (HCVrA) affects up to 4-11% of the subjects suffering from disease. We reported a patient with HCVrA presented with the commonly accepted diagnostic clinical signs and laboratory parameters. The painful joints distinctly demonstrated increased uptake of Tc-99 m methylene diphosphonate in scintigraphy and normal findings in radiography.

Abstract
Extra-hepatic compartments might contribute to hepatitis C virus (HCV) persistence and extra-hepatic manifestations. Therefore, we investigated HCV infection in colonic tissue in patients with chronic hepatitis C (CHC) and its relationship with HCV pathogenesis. Colonic biopsies were collected from three groups with CHC infection: treatment naïve (TN; n=12), non-responders (NR; n=10) to anti-HCV therapy (pegylated interferon-α and ribavirin) and sustained virologic response (SVR; n=10) and from a fourth healthy control group (n=10). Liver biopsies were examined to assess inflammation and fibrosis. HCV infection and colonic T regulatory (Treg) frequency were detected by immunohistochemistry. HCV core and NS3 proteins were detected in B cells and macrophage/monocytes of 42 % and 25 % of TN and 50 % and 30 % of NR, respectively, but not in SVR or control group. The numbers of cells expressing HCV proteins were positively correlated with both HCV viral load and colonic Treg frequency. A significant negative correlation between HCV-expressing cells with both liver inflammation and fibrosis was identified. Our study provides evidence that HCV can infect B cells and macrophages of the colon. The correlations between HCV infection in colonic tissue and HCV viral load and liver pathology underline the significance of this extra-hepatic infection in HCV pathogenesis and response to therapy.

Abstract
Myasthenia gravis is occasionally associated with thymoma that needs surgical resection and may progress to severe respiratory failure. We experienced a rare case of myasthenia crisis during antiviral therapy for chronic hepatitis C, in whom mediastinal thymoma was discovered and successfully managed with surgical thymectomy and meticulous medical care.A 47-year-old-male patient complained of sudden diplopia 1 week after stopping 11-week administration of pegylated-interferon and ribavirin for chronic hepatitis C. Ophthalmologic examinations revealed ptosis on the right eyelid and restricted right eye movement. Myasthenia gravis was confirmed by positive repetitive nerve stimulation test and positive serum antiacetylcholine receptor antibody test, and mediastinal thymoma was found on chest CT scan. The ocular myasthenia gravis progressed to respiratory failure even after discontinuing antiviral treatment but eventually recovered with thymectomy, anticholinesterase administration, steroid pulse therapy, and prolonged ventilator care. We describe the clinical features of this life-threatening complication of interferon treatment along with previous myasthenia crisis cases by interferon for chronic hepatitis C.In patients with chronic hepatitis C who is going to receive interferon-based antiviral treatment, physicians need to keep in mind the potential life-threatening manifestations of myasthenia gravis before and during antiviral treatment especially when patients complain of muscular weakness and easy fatigability.

Abstract
The opportunity for total joint arthroplasty (TJA) in patients with chronic infectious liver disease is rapidly expanding. This is the product of both superior survival of chronic hepatitis patients, evolving implant technologies, and improvement of techniques in TJA. Unfortunately, treating this group of patients is not without significant challenges that can stem from both intrahepatic and extrahepatic clinical manifestations. Moreover, many subclinical changes occur in this cohort that can alter hemostasis, wound healing, and infection risk even in the asymptomatic patient. In this review, we discuss the various clinical presentations of chronic infectious liver disease and summarize the relevant literature involving total joint arthroplasty for this population. Hopefully, through appropriate patient selection and perioperative optimization, treating surgeons should see continued improvement in outcomes for patients with chronic infectious liver disease.

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
There are several extrahepatic cutaneous manifestations associated with hepatitis B and hepatitis C virus infection. Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection. The clinico-pathogenic associations of these skin conditions are not completely defined but appear to involve activation of the host immune system including the complement system. Management of the aforementioned cutaneous manifestations of viral hepatitis is often similar to that done in cases without viral hepatitis, with control of immune activation being a key strategy. In cases associated with hepatitis B and C, control of viral replication with specific antiviral therapy is also important and associated with improvement in most of the associated clinical manifestations.

Abstract
Treatment of hepatitis C virus (HCV) with pegylated interferon and ribavirin (IFN/RBV) can be associated with neuropsychiatric side effects, which may necessitate dose reductions or treatment discontinuation. This study aimed to characterize the time course and predictors of cognitive and affective/mood symptoms after IFN/RBV treatment initiation. Forty individuals enrolled in a longitudinal project underwent comprehensive cognitive, medical, and psychiatric assessment at baseline and 10 weeks, 6 months, 12 months, and 18 months after treatment initiation. Analyses were conducted to determine the prevalence of neurocognitive impairment over time; explicate the relationship between neurocognitive impairment, neuropsychiatric symptoms, and liver disease at each time point; and identify predictors of neurocognitive decline as well as cognitive effects of viral clearance. By 10 weeks after initiating IFN/RBV, the prevalence of neurocognitive impairment rose from 22.5 to 47.4% (p < 0.05). Infection with genotype 1 and premorbid depression were associated with more severe declines (p < 0.05). After 18 months, 42.5% remained neurocognitively impaired, independent of viral clearance, severity of liver disease, and current depressive symptoms. Undetectable viral load was not associated with improvement 18 months after initiating treatment (p > 0.10). Results of the current study indicate that IFN/RBV treatment-emergent neurocognitive declines are significant, prevalent, and may persist long after treatment cessation. Clinicians should monitor cognition throughout the course of treatment for HCV, noting that early declines may indicate individuals at elevated risk for persistent neurocognitive impairment. Longer-term studies are needed to determine whether lasting declines may remit over longer intervals or with newer direct acting agents.

Abstract
With an estimated 3% of the world's population chronically infected, hepatitis C virus (HCV) represents a major health problem for which an efficient vaccination strategy would be highly desirable. Indeed, chronic hepatitis C is recognized as one of the major causes of cirrhosis, hepatocarcinoma and liver failure worldwide and it is the most common indication for liver transplantation, accounting for 40-50% of liver transplants. Much progress has been made in the prevention of HCV transmission and in therapeutic intervention. However, even if a new wave of directly acting antivirals promise to overcome the problems of low efficacy and adverse effects observed for the current standard of care, which include interferon-α and ribavirin, an effective vaccine would be the only means to definitively eradicate infection and to diminish the burden of HCV-related diseases at affordable costs. Although there is strong evidence that the goal of a prophylactic vaccine could be achieved, there are huge development issues that have impeded reaching this goal and that still have to be addressed. In this article we address the question of whether an HCV vaccine is needed, whether it will eventually be feasible, and why it is so difficult to produce.

Measuring the response of extrahepatic symptoms and quality of life to antiviral treatment in patients with hepatitis C. HEPATITIS RESEARCH AND TREATMENT 2013; 2013:910519.

Abstract
Background. HCV infection is associated with musculoskeletal manifestations such as chronic widespread pain, sicca syndrome, polyarthritis, and a reduced HRQOL. Little data is available on the effect of treatment on these manifestations. This study measured changes in extrahepatic symptoms and HRQOL before and after antiviral treatment in a large UK patient cohort. Methods. 118 patients completed HQLQ and rheumatological questionnaires before and after treatment with pegylated interferon-α and ribavirin, with specific regard to chronic widespread pain, sicca syndrome, and sustained virological response. Results. There was significant improvement in HQLQ domains of physical functioning, physical disability, social functioning, limitations and health distress due to hepatitis, and general health. There was significant deterioration in domains of positive well-being, health distress, and mental health. There was a significant decline prevalence of CWP (26.3% versus 15.3%, P = 0.015). Sicca syndrome prevalence fell insignificantly (12.7% versus 11%). SVR was associated positively with all HRQOL changes and significantly with CWP remission. Conclusions. HCV antivirals significantly improve poor HRQOL scores and CWP. Before treatment, both were common, coassociated, and unaccounted for through mixed cryoglobulinemia alone. Although a role of the hepatitis C virus in CWP cannot be deduced by these results, symptomatic improvement via antiviral treatment exists for this subset of patients.

Abstract
While most of those infected with hepatitis C virus (HCV) are asymptomatic or only develop liver manifestations, a significant percentage evolves with autoimmune and lymphoproliferative disorders, resulting in a clinical condition called HCV syndrome. This work involving case studies of six patients with hepatitis C and varied skin manifestation aimed to report skin lesions occurring with HCV infection and its treatment. Skin manifestations in hepatitis C have been based on epidemiological studies. This justifies the need for studies that correlate HCV infection and its treatment with skin manifestations.

Abstract
Vasculitis has long been associated with chronic viral infections, thus the twin perils of the infection and the immune response against it that bedevils the specialties of infection and immunity. After HIV was identified, it too became associated with vasculitic syndromes. Later, hepatitis C virus was also isolated, identified and described with its own spectrum of vasculitic diseases, including hepatitis C virus-associated cryoglobulinaemia. With the increasing prevalence of HIV and hepatitis C virus coinfection, there has come an increasing recognition of the range of vasculitides that can occur in this population leading to significant morbidity, diagnostic and treatment challenges. In this review, we examine the epidemiology, pathogenesis and general principles of treatment of these systemic diseases in HIV/hepatitis C virus coinfected individuals.

Abstract
OBJECTIVE To investigate the prevalence of thyroid dysfunction (TD) and IgG subclasses of thyroid autoantibodies (TAs) and to determine the predictive factors of TD in chronic hepatitis C (CHC) patients. DESIGN Three hundred and twelve untreated hepatitis C virus-infected patients without a history of TD or treatment with thyroid hormones were enrolled in a cross-sectional study. Clinical and biological factors were statistically analyzed to determine the correlation between TD and this patient population. RESULTS The incidence of TD WAS 12.5% in CHC patients. Clinical hypothyroidism (5.8%) and subclinical hypothyroidism (3.8%) were more frequent than clinical hyperthyroidism (1.6%) and subclinical hyperthyroidism (1.3%). The percentage of TA-positive patients was significantly higher in people 60 years than in those 60 years (31.9 VS 18.6%; P=0.042). Positive thyroid peroxidase antibody (TPOAb) was more frequent, and alanine aminotransferase (ALT) levels were lower in patients who displayed TD (TPOAb: 62.1 vs 10.8%, P=0.000; ALT: 43.5 vs 51 IU/l, P=0.046). The positive percentage of TPOAb IgG2 subclass in the TD group was significantly higher than that of patients without TD (66.7 vs 16.7%, P=0.005). Multiple logistic regression analysis indicated that only TPOAb IgG2 subclass positivity was an independent risk factor for TD in CHC patients (odds ratio=8; 95% CI: 1.225-52.246; P=0.030). CONCLUSIONS TPOAb IgG2 subclass positivity is a risk factor for TD in CHC patients before antiviral treatment. IgG2 subclass of TPOAb might play an important role in the presence of TD in CHC patients.

Abstract
Hepatitis C virus (HCV) infection in more than 170 million chronically infected patients with no developed preventive vaccine is a globally important issue. In addition to expected hepatic manifestations, a number of extrahepatic manifestations, such as mixed cryoglobulinemia, glomerulonephritis, polyarteritis nodosa, rashes, renal disease, neuropathy, and lymphoma, have been reported following HCV infection, which are believed to be influenced by the virus or the host immune response. HCV combination therapy with pegylated interferon and ribavirin might be associated with side effects as well. The association of HCV with special oral conditions has also been reported recurrently; the mechanism of most of which remains unclear. This article reviews the association of HCV infection with some of the oral conditions such as oral health, Sjogren's syndrome, lichen planus and oral cancer.

Vasculitic leg ulcers are a cutaneous manifestation of hepatitis C virus (HCV) infection often associated with cryoglobulinemia. Their treatment is difficult and is based on steroids and immunosuppressive drugs with an erratic response and a high probability of adverse reaction. We report three patients with vasculitic leg ulcers associated with hepatitis C virus infection who were treated successfully with rituximab. The pain control and healing were achieved quickly. No adverse effects with rituximab in these patients were presented.

Abstract
Hepatitis C virus (HCV) infection is a growing international health problem, and more than 170 million people are chronic carriers. Up to 50% of HCV-positive patients develop at least one extrahepatic manifestation during the course of disease. To varying degrees of certainty, there is evidence of an association between chronic HCV infection and a variety of neuromuscular diseases. The pathogenesis of most extrahepatic diseases remains unclear but possibly includes HCV lymphotropism and/or HCV-induced autoantibodies. The therapeutic approach to HCV-associated autoimmune disorders entails eradication of HCV with one of the recombinant interferon-alpha preparations with or without additional immunosuppressive drugs.

Abstract
OBJECTIVE To evaluate the rate of pediatric hepatitis C virus (HCV) case ascertainment relative to the estimated number of actual cases. STUDY DESIGN Data from Florida and United States health departments were used to assess pediatric HCV case ascertainment rates in Florida and nationwide. The percentage of children infected with HCV from Miami-Dade County receiving medical care by a pediatric gastroenterologist was estimated based on data obtained from physician questionnaires. RESULTS From 2000 through 2009, 2007 children were identified as having positive HCV antibody tests in Florida, only 12% of the expected number (n = 12 155). An estimated 1.6% of the expected children with HCV who tested Ab-positive (37 of 1935) were actively followed by a pediatric gastroenterologist in Miami-Dade County, Florida. Across the United States, only 4.9% of the expected cases have been identified. CONCLUSIONS The identification of children infected with HCV in the nation as a whole is grossly inadequate. Only a small fraction of cases are identified. In Florida, less than 2% of children identified receive treatment. Lack of identification and lack of treatment of children infected with HCV constitute critical public health problems. Strategies to increase awareness of HCV infection and to screen at-risk individuals could substantially improve morbidity and mortality while reducing health care costs.

Abstract
Mixed cryoglobulinemia (MC) is a syndrome resulting from cold-insoluble immunoglobulin complexes or cryoglobulins (CGs) that precipitate in the serum of 40% to 50% of patients with chronic hepatitis C virus (HCV) infection. The pathogenesis of cryoglobulinemia likely occurs due to chronic viremia and generation of rheumatoid factor following continuous presentation of antigen-immunoglobulin complexes to B cells. CGs are thought to be responsible for a variety of extrahepatic manifestations associated with HCV, including vasculitis, glomerulonephritis, arthritis, and neuropathies, which occur in approximately 10% of HCV patients with CGs. CGs also are a powerful predictive factor for progressive liver disease and the aggressive reoccurrence of liver disease in HCV-positive patients after liver transplantation. First-line therapy for MC due to HCV infection is antiviral therapy with pegylated interferon-alpha and ribavirin. Viral eradication usually produces marked reduction of physical complications and arrests end organ damage concomitant with clearance of CG. Additional prospective, controlled studies are necessary to determine whether CG influences patient virologic response and/or its durability to antiviral therapy. Immunomodulators such as corticosteroids and cyclophosphamide are efficacious for palliative treatment of the symptomatology of HCV cryoglobulinemia but may enhance viral replication. Consequently, prolonged therapy with immunomodulatory agents should be limited to severe vasculitis or aggressive glomerulonephritis in patients with MC due to HCV who have failed to respond to antiviral therapy. In acute, fulminant presentations, plasmapheresis may provide temporary relief and arrest the rapid progression of the disease so that additional therapy can be initiated.

Abstract
Cirrhosis and hepatocellular carcinoma are the prototypic complications of chronic hepatitis C virus infection in the liver. However, hepatitis C virus also affects a variety of other organs that may lead to significant morbidity and mortality. Extrahepatic manifestations of hepatitis C infection include a multitude of disease processes affecting the small vessels, skin, kidneys, salivary gland, eyes, thyroid, and immunologic system. The majority of these conditions are thought to be immune mediated. The most documented of these entities is mixed cryoglobulinemia. Morphologically, immune complex depositions can be identified in small vessels and glomerular capillary walls, leading to leukoclastic vasculitis in the skin and membranoproliferative glomerulonephritis in the kidney. Other HCV-associated entities include porphyria cutanea tarda, lichen planus, necrolytic acral erythema, membranous glomerulonephritis, diabetic nephropathy, B-cell non-Hodgkin lymphomas, insulin resistance, sialadenitis, sicca syndrome, and autoimmune thyroiditis. This paper highlights the histomorphologic features of these processes, which are typically characterized by chronic inflammation, immune complex deposition, and immunoproliferative disease in the affected organ.

Abstract
Hepatitis C virus (HCV) infection remains a major global health burden. Hepatitis C causes significant liver-related morbidity and mortality due to hepatic decompensation and development of hepatocellular carcinoma. In addition, extra-hepatic manifestations of hepatitis C are frequent. There is a very large interindividual variability in the natural history of both acute and chronic hepatitis C which can be explained in part by a combination of various host, viral and environmental factors. Successful antiviral treatment can prevent short- and long-term complications of HCV infection in many patients. Still, the relative contribution of distinct risk factors for disease progression in different phases of HCV infection needs to be better defined. Personalized treatment approaches for HCV infection should consider individual risk profiles to avoid both under- and over-treatment - which will remain important also in upcoming era of interferon-free treatment of hepatitis C.

Dermatological side effects of hepatitis C and its treatment: patient management in the era of direct-acting antivirals. J Hepatol 2012; 56:455-63. [PMID: 21884670 DOI: 10.1016/j.jhep.2011.08.006] [Citation(s) in RCA: 104] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2011] [Revised: 07/26/2011] [Accepted: 08/02/2011] [Indexed: 12/15/2022]
Abstract
Dermatological adverse events (AEs) are an existing concern during hepatitis C virus (HCV) infection and peginterferon/ribavirin treatment. HCV infection leads to dermatological and muco-cutaneous manifestations including small-vessel vasculitis as part of the mixed cryoglobulinemic syndrome. Peginterferon/ribavirin treatment is associated with well-characterized dermatological AEs tending towards a uniform entity of dermatitis. New direct-acting antivirals have led to significant improvements in sustained virologic response rates, but several have led to an increase in dermatological AEs versus peginterferon/ribavirin alone. In telaprevir trials, approximately half of treated patients had rash. More than 90% of these events were Grade 1 or 2 (mild/moderate) and in the majority (92%) of cases, progression to a more severe grade did not occur. In a small number of cases (6%), rash led to telaprevir discontinuation, whereupon symptoms commonly resolved. Dermatological AEs with telaprevir-based triple therapy were generally similar to those observed with peginterferon/ribavirin (xerosis, pruritus, and eczema). A few cases were classified as severe cutaneous adverse reaction (SCAR), also referred to as serious skin reactions, a group of rare conditions that are potentially life-threatening. It is therefore important to distinguish between telaprevir-related dermatitis and SCAR. The telaprevir prescribing information does not require telaprevir discontinuation for Grade 1 or 2 (mild/moderate) rash, which can be treated using emollients/moisturizers and topical corticosteroids. For Grade 3 rash, the prescribing information mandates immediate telaprevir discontinuation, with ribavirin interruption (with or without peginterferon) within 7 days of stopping telaprevir if there is no improvement, or sooner if it worsens. In case of suspicion or confirmed diagnosis of SCAR, all study medication must be discontinued.

Abstract
BACKGROUND Hepatitis C virus (HCV) chronic infection affects 10% to 15% of patients with bipolar disorder. Patients with HCV infection and comorbid psychiatric illness pose a tremendous clinical and therapeutic challenge. The cases presented in this report illustrate several critical issues facing clinicians who manage patients with comorbid HCV infection and bipolar disorder. METHOD Five cases are described in which patients with DSM-IV bipolar disorder were treated with interferon-alpha-based therapies and ribavirin to induce viral clearance of HCV. In all cases, the patients were treated using an integrated model of care, and the treatment decision was a consensus between the treating hepatologists and psychiatrists. RESULTS In the first case, the patient had no significant neuropsychiatric adverse effects and had viral clearance. In 2 other cases, viral clearance of HCV was achieved through the delicate management of affective symptoms induced by interferon-alpha and ribavirin. Interferon-alpha and ribavirin treatment was halted due to mania and suicidal ideation in the 2 remaining cases. CONCLUSION These cases suggest that patients with hepatitis C and bipolar disorder should be evaluated for HCV antiviral treatments, as these patients can receive and tolerate these treatments if assessed meticulously, observed carefully, and followed extensively during interferon-alpha and ribavirin treatment. This case series will hopefully spark a dialogue about when HCV antiviral treatment should be withheld or delayed in these difficult cases.

Abstract
Virus-induced spinal cord damage results from a cytolytic effect on anterior horn cells or from predominantly cellular immune-mediated damage of long white matter tracts. Infection with the hepatitis virus group, most notably hepatitis C virus, has infrequently been associated with the occurrence of myelitis. The pathogenesis of hepatitis virus-associated myelitis has not been clarified: virus-induced autoimmunity (humoral or cell-mediated, possibly vasculitic) seems the most likely disease mechanism. Limited available information offers no evidence of direct hepatitis virus infection of the spinal cord. Virus neuropenetration may occur after virus-infected mononuclear cells penetrate the blood-brain barrier, but a true neurolytic effect has not been demonstrated. Attacks of acute myelitis usually respond favorably to immunomodulatory therapy. Antiviral therapy plays no confirmed role in the treatment of acute bouts of myelitis, but may limit the relapsing course of HCV-associated myelitis.

Abstract
Hepatitis C virus (HCV) infection appears to contribute to the development of insulin resistance (IR). Among the multiple determinants of IR, body mass index (BMI) is the most important. We investigated the contribution of HCV to BMI-associated IR using a transgenic mouse model expressing HCV core protein. Eight transgenic and five nontransgenic littermate controls were evaluated. Glucose and insulin tolerance tests (ITT) were performed on two separate occasions. Multivariate linear mixed modelling was used to evaluate and compare the effect of weight on IR between HCV core transgenic and nontransgenic controls. There were no statistically significant differences in glucose or ITT (P = 0.58 and P = 0.59, respectively) between the two groups, and no difference in median weights between transgenic and control mice (P = 0.11). However, there was greater variance in the distributions of Tg when compared to nontransgenic mice for both glucose and insulin tolerance. When evaluating this closely, a differential contribution of weight to IR curves between these groups was noted (P = 0.05). Among nontransgenic mice, IR curves for mice of different weights were comparable, however, for transgenic mice, higher weights resulted in larger levels of IR curves with slower decay. In all animals, steatosis was absent or minimal. We conclude that weight has a greater effect on IR in HCV core expressing transgenic mice than littermate controls. HCV therefore synergizes with weight in the promotion of IR. Steatosis was not a prerequisite for the development of IR, implying that HCV's effects on IR may be independent of steatosis.

Abstract
PURPOSE To assess the prevalence and predictive factors of extrahepatic manifestation (EM) in patients with chronic hepatitis C (CHC) infection in Poland. MATERIAL AND METHODS 340 consecutive patients (mean age: 42 years) with untreated CHC were studied between 2000 and 2006. The HCV infection was defined by positive serology and serum HCV RNA. The inflammation grade and fibrosis stage were assessed according to Ishak. Demographic, laboratory and liver biopsy data were collected. The patients with liver cirrhosis, concomitant HBV or HIV infection, autoimmune liver diseases and alcohol abusers were excluded from the analysis. RESULTS 210 patients with CHC (61.7%) presented at least 1 extrahepatic manifestation, including mixed cryoglobulinemia (37.1%), thrombocytopenia (27.6%), thyroid autoimmunity (16.2%), dermatological disorders (4.1%) and type 2 diabetes (4.1%). Other EM such as the sicca syndrome, nephropathy, polyneuropathy and B-cell lymphoma were observed in single cases. In multivariate analysis lower platelet count was found as a predictive factor of EM in patients with CHC. CONCLUSIONS The majority of patients with CHC, living in Poland, have EM, of which cryoglobulinemia, thrombocytopenia, thyroid autoimmunity, dermatological disorders and type 2 diabetes are most common. Through the multivariate analysis the lower platelet predicts extrahepatic manifestations associated with chronic hepatitis C.

Abstract
OBJECTIVES The aim of this work is to investigate the association between transfusion history and cancer mortality in a prospective follow-up study. METHODS We conducted a prospective cohort study in four areas of Akita Prefecture, Japan, in 10,451 individuals (4,401 men and 6,050 women, aged 40-79 years) without history of cancer. The subjects were followed until 31 December 2003 and the number of deaths from cancer was recorded. RESULTS After mean follow-up of 12.76 years (140,259 person-years), 520 individuals (333 men and 187 women) died of cancer. History of blood transfusion before 1990 was mildly but significantly associated with overall cancer mortality (hazard ratio = 1.75, 95% confidence interval: 1.32-2.18) and nonliver cancer mortality (HR = 1.68, 95% CI: 1.25-2.26). This significant association remained unchanged after excluding deaths that occurred within 5 years of baseline for overall cancer mortality (HR = 1.47, 95% CI: 1.04-2.09) and for nonliver cancer mortality (HR = 1.43, 95% CI: 1.00-2.04). The significant association for nonliver cancer mortality was confirmed in subjects with no smoking history and/or alcohol consumption (HR = 2.01, 95% CI: 1.35-3.00). Site-specific analysis showed a possible association between transfusion history and death from pancreatic cancer. CONCLUSIONS History of blood transfusion before 1990 was found to be associated with increased risk for cancer mortality and was independent of liver diseases. The mechanism of the association between blood transfusion and cancer mortality warrants further research.

Abstract
Mixed cryoglobulinemia is a chronic immune complex-mediated disease strongly associated with hepatitis C virus (HCV) infection. Mixed cryoglobulinemia is a vasculitis of small and medium-sized arteries and veins, due to the deposition of complexes of antigen, cryoglobulin and complement in the vessel walls. The main clinical features of mixed cryoglobulinemia vasculitis include the triad of palpable purpura, arthralgias, and weakness, and other pathological conditions such as glomerulonephritis, peripheral neuropathy, skin ulcers, and widespread vasculitis. The treatment of HCV-related mixed cryoglobulinemia is difficult due to the multifactorial origin and clinical polymorphism of the syndrome. It can be directed to eradicate the HCV infection, suppress the B-cell clonal expansion and cryoglobulin production, or ameliorate symptoms. The choice of the most appropriate treatment is strictly related to the assessment of disease activity, and to the extent and severity of organ involvement.

Abstract
Hepatitis C virus (HCV) is an important causative agent of liver diseases. However, HCV infection is also associated with numerous hematologic, renal, dermatologic, rheumatic, and autoimmune disorders. These include arthralgia, arthritis, vasculitis, sicca syndrome, myalgia, and fibromyalgia. The purpose of this article is to review the prevalence and spectrum of rheumatic disorders and autoimmune phenomena in HCV-infected patients. It evaluates and current treatment options including nonsteroidal anti-inflammatory drugs, low-dose corticosteroids, hydroxychloroquine, methotrexate, penicillamine, combined antiviral therapy, cyclosporin A, anti-TNF-a agents, and rituximab. It concludes that larger, controlled studies are needed to establish further the treatment indications, efficacy, and safety of these agents.

Abstract
Since the identification of hepatitis C virus (HCV) in 1989 as a causative agent for a number of the extrahepatic alterations related to HCV infection an underlying immune mediated pathogenetic mechanism has been postulated. HCV-associated thrombocytopenia may be considered complex and multifactorial in origin, since different mechanisms have been implicated in its pathophysiology. With respect to autoimmune thrombocytopenia in chronic HCV infection, the detection of specific antibodies against platelet glycoproteins have been reported only in a few studies, but no systematic study has been carried out. We examined the clinical, laboratory, and virological characteristics of a case series of 10 patients with autoimmune thrombocytopenia (platelet count <150.0 x 10(9)/L) related to chronic HCV infection. Cases, six males and four females, aged 57.1 +/- 12.6 years, presented high titers of antibodies against platelet glycoprotein (GP) IIb/IIIa, GP Ia/IIa, and/or GP Ib/IX, and no other mechanism involved in the pathogenesis of HCV-associated thrombocytopenia was identified. Furthermore, cases were not associated with particular HCV genotype. Complete platelet response was observed in two patients treated with pegylated interferon plus ribavirin, and partial platelet response was seen in two patients treated with anti-D Ig and one patient treated with corticosteroids. These findings indicate that an autoimmune mechanism may play a role in the pathogenesis of HCV-associated thrombocytopenia in a proportion of these patients.
