Abstract
INTRODUCTION Chronic hepatitis C virus (HCV) infection has been associated with myriad extrahepatic manifestations, often resulting from aberrant immune responses. Among the most common immune-mediated manifestations of HCV infection, mixed cryoglobulinemia is the best known extra-hepatic complication. Areas covered: Here we review less common extrahepatic manifestations of HCV infection, with ascertained or presumed immune pathogenesis and the role of the new all oral direct-acting antiviral agents. Rheumatologic, dermatologic, ophthalmologic, renal, pulmonary, hematologic, cardiovascular, and neuropsychiatric manifestations of HCV infection have been considered. Expert commentary: Pathogenesis of HCV-induced aberrant immune responses resulting in peculiar clinical manifestations is not restricted to a single mechanism. A sound approach would therefore consider implementation of an etiologic treatment, through use of antiviral medications, to stop upstream in the pathogenic process all the immune mechanisms leading to hepatic and extrahepatic abnormalities. With the recent introduction of interferon-free, direct antiviral agents, capable of warranting cure for nearly all HCV-infected patients subjected to therapy, both common and uncommon extrahepatic manifestations of chronic hepatitis C are expected to no longer constitute a matter of comorbidity in the course of HCV infection.

Abstract
Chronic viral infections including those by hepatitis B (CHB) virus and hepatitis C (CHC) virus have been reported to be comorbidities of chronic spontaneous urticaria (CSU). Here, we performed the first comprehensive review of the peer-reviewed literature (PubMed, Web of Science and Google Scholar) on the prevalence of CHB and CHC in patients with CSU and vice versa. The prevalence of CHB and CHC in CSU does not appear to be increased. Less than 5% and 2% of patients with CSU have markers of CHB and CHC, respectively, according to most of the 32 studies reviewed. Urticarial rash including CSU occurs in ≤3% of patients with CHC as reported by most of 20 studies analysed. Very few patients have been assessed for the effects of antiviral hepatitis treatment on their CSU, and two but not all reportedly showed improvement. Hepatitis B/C infections appear unlikely to be linked to CSU. We suggest that routine screening for these infections in patients with CSU is not relevant or cost-effective and should not be performed unless liver function tests are abnormal, risk factors or symptoms of viral hepatitis are present, or urticarial vasculitis is suspected.

Abstract
A 62-year-old white woman with a history of hepatitis C and type 2 diabetes mellitus developed urticaria during treatment with ustekinumab for plaque psoriasis. The patient received two 45-mg ustekinumab injections in her first 2 months and then one 45-mg injection every 3 months for her psoriasis. After 10 months, she developed a round red rash on her skin diffusely on her body. She also complained of joint pain in her hands. Rheumatology became involved, and investigations revealed that her antinuclear antibody titer was negative, but her rheumatoid factor, erythrocyte sedimentation rate, and liver function enzymes were elevated. She was diagnosed with urticaria, and ustekinumab was discontinued. A Naranjo assessment score of 6 was obtained, indicating a probable relationship between the patient's urticaria and her use of ustekinumab. Ustekinumab was subsequently discontinued, and the patient received a course of Harvoni® (Gilead Sciences, Inc., Forest City, California, United States) (ledispasvir/sofosbuvir) with clearance of the hepatitis C virus. The patient is currently receiving another biologic agent, ixekizumab, and reports no complaints, including that of urticaria.

Abstract
This guidance for the management of patients with chronic urticaria and angioedema has been prepared by the Standards of Care Committee of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is aimed at both adult physicians and paediatricians practising in allergy. The recommendations are evidence graded. During the development of these guidelines, all BSACI members were included in the consultation process using a Web-based system. Their comments and suggestions were carefully considered by the Standards of Care Committee. Where evidence was lacking, a consensus was reached by the experts on the committee. Included in this management guideline are clinical classification, aetiology, diagnosis, investigations, treatment guidance with special sections on children with urticaria and the use of antihistamines in women who are pregnant or breastfeeding. Finally, we have made recommendations for potential areas of future research.

Abstract
Urticaria has a documented association with the prodromal phases of hepatitis A, B and, although still contentious, likely hepatitis C. Despite the documented association there are few actual reported cases of urticaria occurring with hepatitis A infection and in all of the cases reported so far the urticaria preceded the diagnosis of hepatitis A and was acute rather than chronic. We describe a case of urticaria occurring following acute infection with hepatitis A, which persisted beyond 6 weeks and therefore was by definition chronic. Although chronic urticaria has been reported to be associated with other forms of viral hepatitis, to the best of our knowledge this has not been reported previously with hepatitis A.

Abstract
OBJECTIVE The main objective of this study was to estimate the prevalence of hepatitis C virus (HCV) infection and to determine the HCV genotypes in urticaria patients of Saudi Arabia. METHODS After thorough clinical examination by a consultant dermatologist, urticaria patients and individual healthy controls were enrolled. Venous blood collected from subjects was analyzed for LFT (aspartate transaminase [AST], alanine transaminase [ALT], albumin, and bilirubin), hepatitis B surface antigen (HBsAg), and HCV antibodies--HCV-RNA-PCR screening and genotyping. RESULTS Upon enzyme immunoassay (EIA) screening for HCV infection, 5/70 (7.1%) urticaria patients and none among the controls tested positive for the presence of anti-HCV antibodies (p=0.005). Genotyping analysis revealed that HCV belongs to types 3 and 4 with subtypes 3a, 4a, and 4c. No significant variations were seen in the mean serum levels of ALT, AST, albumin, and bilirubin between the patients based on their HCV sero-positivity status. CONCLUSION This prospective study indicated that HCV infection plays a significant role in urticaria. However, larger studies in different ethnicities could ascertain the association between different HCV genetic variants and the urticaria.

Abstract
BACKGROUND The causal association between hepatitis virus infections and lichen planus (LP) remains a matter of controversy. Reliable figures for German patients are still lacking. PATIENTS AND METHODS We analyzed the prevalence of serum antibodies against hepatitis B and C viruses (HBV, HCV) in 265 LP patients and compared the results to 257 patients with chronic urticaria (URT) and 222 patients with malignant melanoma (MM). Additionally, we analyzed age- and sex-specific differences. RESULTS The prevalence of HBV (13.2 % or 14.7 %) antibodies was significantly higher in patients with LP and URT patients than in the MM control group (HBV: 5.4 %, p < 0.001). The prevalence of HCV antibodies among LP and URT patients (2.6 % or 0.8 %) was not significantly greater (p > 0.05) than in MM patients (0.4 %). The prevalences of HBV and HCV in the MM control group were comparable to those in the general German population (HBV: 5-8 %, HCV: 0.4-0.7 %). An analysis by sub-groups showed that these differences resulted from sex- and age-dependent prevalences. HBV antibodies were significantly more common only in male LP patients (16.1 %) and in male (20.0 %) and female URT patients (15.6 %) aged 31-60 years. The greater prevalence of HCV in female LP patients older than 60 years of age was not significant. CONCLUSIONS LP is not specifically associated with hepatitis B or C antibodies in the Caucasian population of Germany. The higher prevalences of HBV antibodies found in LP and URT patients may be a reflection of age- and sex-related factors rather than disease-specific exposure to HBV infections. The increased prevalences seen in patients with LP or URT compared to MM patients may suggest that HBV infection serves as an unspecific trigger for a specific immune reaction of another origin.

Abstract
Urticaria is often classified as acute, chronic, or physical based on duration of symptoms and the presence or absence of inducing stimuli. Urticarial vasculitis, contact urticaria, and special syndromes are also included under the broad heading of urticaria. Recent advances in our understanding of the pathogenesis of chronic urticaria include the finding of autoantibodies to mast cell receptors in nearly half of patients with chronic idiopathic urticaria. These patients may have more severe disease and require more aggressive therapies. Extensive laboratory evaluation for patients with chronic urticaria is typically unrevealing and there are no compelling data that associate urticaria with chronic infections or malignancy. Pharmacologic therapy consists primarily of the appropriate use of first- and second-generation histamine H(1) receptor antihistamines. Additional therapy may include leukotriene receptor antagonists, corticosteroids, and immunomodulatory agents for severe, unremitting disease. Despite our greater understanding of the pathogenesis of urticaria, the condition remains a frustrating entity for many patients, particularly those with chronic urticaria.

Abstract
PURPOSE OF REVIEW The pathogenesis of chronic urticaria is multifactorial and a specific treatment is lacking. In acute urticaria there is no doubt of a causal relationship with infections and all chronic urticaria must start as the acute form. However, in the chronic form a primary role for infection is controversial, although it is undeniable that concurrent infections exacerbate the condition. This is the first English language review based on a detailed analysis of current peer-reviewed publications dealing with infections and chronic urticaria. RECENT FINDINGS In chronic urticaria there is a lot of evidence for different infections, but randomized controlled trials are missing. The prevalence of infections is not increased but in susceptible patients the immune response may lead to the development of chronic urticaria. Interestingly, there is evidence for an infection-associated autoreactive response at least in the subgroup with a positive autologous serum skin test. A variety of mechanisms have been invoked to explain these observations, including molecular mimicry. SUMMARY Actually the arguments for an important role of underlying causal infections in chronic urticaria are weak, from an evidence-based viewpoint, but there are data suggesting a link. Moreover, an association with underlying or precipitating infectious causes is difficult to establish because there is no possibility for challenge and the number of other urticarial triggers is vast. For the future it will be necessary to reveal the link between urticaria, autoreactivity, non-immunoglobulin E-mediated hypersensitivity reactions and infections to find attractive and specific therapeutic interventions for urticarial symptomatology.

Abstract
Chronic urticaria is a common condition that can be very disabling when severe. A cause for chronic idiopathic urticaria (CIU) is only infrequently identified. Potential causes include reactions to food and drugs, infections (rarely) and, apart from an increased incidence of thyroid disease, uncomplicated urticaria is not usually associated with underlying systemic disease or malignancy. About one-third of patients with CIU have circulating functional autoantibodies against the high affinity IgE receptor or against IgE, although it is not known why such antibodies are produced, or how the presence of such antibodies alters the course of the disease or response to treatment. There are only a few publications relating to childhood urticaria, but it is probably similar to the adult form, except that adult urticaria is more common. The diagnosis is based on patient history and it is vital to spend time documenting this in detail. Extensive laboratory tests are not required in the vast majority of patients. Chronic urticaria resolves spontaneously in 30-55% of patients within 5 years, but it can persist for many years. Treatment is aimed firstly at avoiding underlying causative or exacerbating factors. Histamine H1 receptor antagonists remain the mainstay of oral treatment for all forms of urticaria. The newer low-sedating antihistamines desloratadine, fexofenadine, levocetirizine and mizolastine should be tried first. Sedating antihistamines have more adverse effects but are useful if symptoms are causing sleep disturbance. Low-dose dopexin is effective and especially suitable for patients with associated depression. There is controversy as to whether the addition of an histamine H2 receptor antagonist or a leukotriene antagonist is helpful. For CIU, second-line agents include ciclosporin (cyclosporine) [which is effective in approximately 75% of patients], short courses of oral corticosteroids, intravenous immunoglobulins and plasmapheresis, although the last two were found to be beneficial in small trials only. Treatments for CIU with only limited or anecdotal supportive evidence include sulphasalazine, methotrexate, stanazol, rofecoxib and cyclophosphamide. The efficacy of photo(chemo)therapy is controversial. Physical urticarias may respond to H1 receptor antagonists, although in delayed pressure urticaria, and cold, solar and aquagenic urticaria, the response may be disappointing. Second-line agents for physical urticarias vary depending on the urticaria and most have limited supportive evidence. The potential for spontaneous resolution, the variation in the disease activity and the unpredictable nature of the disease makes the efficacy of treatments difficult to assess.

Abstract
Urticaria is a common disorder affecting one-fifth of the world's population. The pathophysiology is characterized by an increased propensity for mast cell degranulation with the release of potent mediators into the dermal and subdermal tissues with resulting vasoactive, chemotactic, and inflammatory effects. The final clinical manifestation of the typical urticarial lesion is the effect of several diverse effects and causes. The general classification is acute, chronic, and physical urticaria. In general, allergenic triggers can be identified in between 60-80% of acute urticarias. Physical urticarias are characterized by the onset after the specific inciting stimulus, which can reproduce the characteristic lesion which is usually of shorter duration (with the exception of delayed pressure urticaria). Chronic idiopathic urticaria is associated with thyroid autoimmunity and, more recently, anti-mast cell receptor antibodies. An extensive work-up is usually not indicated or helpful in identifying a cause. Food or other allergens are rare causes of this type of presentation. The evaluation and work-up is dependent on clues identified by history. The treatment is removal of specific and non-specific triggers and the use of symptomatic medications generally attenuating the mediator effects.

Abstract
Hepatitis C is an important and common cause of chronic hepatitis and cirrhosis. Cutaneous manifestations are often the first signs of infection. Dermatologists must be aware of these manifestations, because early diagnosis is the best treatment. HCV Ab by ELISA should be ordered in patients with LCV-urticarial vasculitis, cryoglobulinemia, lichen planus, Sjögren's syndrome, unexplained pruritus, PCT, PAN, chronic urticaria, patients starting methotrexate, unexplained pruritus, and any patient initiating therapy with a potentially hepatotoxic drug.

Abstract
Viral hepatitis is a common disease with significant morbidity and mortality that is found throughout the world. It is a known cause of acute and chronic liver disease. Because the disease can be asymptomatic in its acute stages, the diagnosis is often missed. This article reviews the extrahepatic manifestations of the disease, in particular the visible cutaneous lesions, which offer clues to the diagnosis of viral hepatitis. Familiarity with the most common skin lesions associated with each type of hepatitis virus will be useful in identifying previously undiagnosed individuals. This article serves as a review of the most widely published associations between skin diseases and specific subtypes of viral hepatitis.

Abstract
Hepatitis C virus (HCV) is a common cause of chronic hepatitis and is frequently associated with extrahepatic disease. Recently, cutaneous disorders have been a presenting manifestation of HCV infection. Porphyria cutanea tarda (PCT) is one of the cutaneous diseases associated with hepatitis C. PCT manifests in an acute form with tense bullae and erosions and in a chronic form with milia, scarring, and sclerodermatous changes. HCV has also been implicated as a cause of vasculitis through immune complex deposition. We report a patient in whom HCV was associated with sclerodermoid PCT and a medium vessel vasculitis. This case underscores the importance of HCV and its potential cutaneous manifestations, as well as the importance of recognizing cutaneous manifestations of internal disease that may be the first clue to diagnosis of HCV.
