Prurigo nodularis (PN) is a skin disease that develops on chronically itchy skin. There are various causes behind the chronic itch. Due to intensive research in recent years different mechanisms that can participate in the development of chronic pruritus have been discovered, opening up new therapeutic targets for treatment. Here we review the various mechanisms behind chronic pruritus and discuss the novel therapies for PN.

Pruritus represents one of the most common symptoms in dermatology and general medicine. Chronic pruritus severely impairs the quality of life of affected patients. During the last two decades a number of modulators and mediator of pruritus have been identified. Recently, Interleukin (IL)-31 and its receptor complex attracted significant interest, as clinical phase two studies demonstrated therapeutic efficacy of the neutralizing IL-31 receptor A (IL-31RA) antibody nemolizumab in patients suffering from atopic dermatitis or prurigo nodularis. IL-31 has also been shown to play relevant roles in allergic contact dermatitis, urticaria, mastocytosis, allergic rhinitis and asthma. Here, we summarize the current knowledge of the novel cytokine IL-31 and its receptor regarding cellular origin, regulation, signaling pathways and their involvement in biological processes such as pruritus, neuronal growth, inflammation, barrier dysfunction and tissue remodeling.

This article explores the diversity of British literary responses to Diaghilev's project, emphasising the way in which the subject matter and methodologies of Diaghilev's modernism were sometimes unexpectedly echoed in expressions of contemporary British writing. These discussions emerge both in writing about Diaghilev's work, and, more discretely, when references to the Russian Ballet find their way into the creative writing of the period, serving to anchor the texts in a particular cultural milieu or to suggest contemporary aesthetic problems in the domain of literary aesthetics developing in the period. Figures from disparate fields, including literature, music and the visual arts, brought to their criticism of the Ballets Russes their individual perspectives on its aesthetics, helping to consolidate the sense of its importance in contributing to the inter-disciplinary flavour of modernism across the arts. In the field of literature, not only did British writers evaluate the Ballets Russes in terms of their own poetics, their relationship to experimentation in the novel and in drama, they developed an increasing sense of the company's place in dance history, its choreographic innovations offering material for wider discussions, opening up the potential for literary modernism's interest in impersonality and in the ‘unsayable’, discussions of the body, primitivism and gender.

This essay combines a consideration of the two-decades-long publishing strategy of Goethe's last major prose work, Wilhelm Meisters Wanderjahre (1808–29), with a reading of specific formal features unique to the final version of the novel. In doing so, it argues that Goethe's use of print and narrative work in concert to form what we might call a particular media imaginary–to reimagine the printed book not according to emerging nineteenth-century criteria of sovereignty, nationality, and permanence but instead according to values more in keeping with the technological capabilities of print media, such as transformation, diffusion, and connectivity. In his vigorous engagement with the material manifestations of his work as a key site of literary work, Goethe offers us an ideal place to explore the productive intersections that the disciplines of book history and literary history are opening up today.

Covid-19 is a pandemic and the whole world is facing the loss in terms of morbidity and mortality of the human resources. Therefore, there is an urgent need for various therapeutic agents or drugs to treat the covid-19 patients. Although, vaccination process is under way, it is not possible to provide the vaccination to whole world in a short period. Therefore, it is an essential strategy to work on the various therapeutic aspects of covid-19 treatment. The present book chapter will discuss and review the various aspects of the treatment strategies of the covid-19. Further, we will provide an overview of the virus and host based potential therapeutic targets along with existing therapeutics which are effective against SARS-CoV-2 virus. Also, the novel vaccines are being developed against covid-19 deadly virus will be discussed.

Inflammatory bowel disease, consisting of Crohn’s disease and ulcerative colitis, causes chronic gastrointestinal symptoms and can lead to morbidity and mortality if uncontrolled or untreated. However, for patients with moderate-to-severe disease, currently available therapies do not induce or maintain remission in >50% of patients. This underscores the need for additional therapies. In this review, the authors detail the novel therapies vedolizumab, tofacitinib, and ustekinumab and delve into therapies which may come onto the market within the next 10 years, including JAK-1 inhibitors (filgotinib and upadacitinib), IL-23 inhibitors (guselkumab, mirikizumab, and risankizumab), the anti-β4β7 and anti-βEβ7 integrin monoclonal antibody etrolizumab, the sphingosine-1-phosphate subtypes 1 and 5 modulator ozanimod, and mesenchymal stem cells. Further studies are required before these emerging therapies gain approval.

Background: Chronic pruritus is a debilitating condition associated with a wide range of dermatologic, systemic and psychogenic etiologies. In patients with chronic pruritus that is refractory to conventional therapy, symptoms can significantly decrease quality of life by contributing to anxiety, sleep disturbances, and in many cases depression. Recent studies have demonstrated the effectiveness of mirtazapine in relieving chronic itch that is refractory to standard first-line therapies. Methods: We searched PubMed for English-language articles containing the words (“pruritus” or “itch”) AND “antidepressant” and then conducted a systematic review of the current literature to summarize the efficacy of mirtazapine in treating chronic itch. Results: All studies reported a reduction in itch intensity following the administration of mirtazapine. Conclusion: Collectively, these studies suggest the potential for mirtazapine to relieve chronic itch attributed to dermatological causes and malignancies. As, such mirtazapine may be an option for patients with chronic pruritus that is refractory to typical first-line treatments.

Abstract Background TTC7A mutation is a rare autosomal recessive disease that can present with various phenotypes including multiple intestinal atresia (MIA), very early onset inflammatory bowel disease (VEOIBD), and profound combined immunodeficiency with hypoplastic thymus, altered T- and B-cell maturation, lymphopenia, monocytosis and agammaglobulinemia. Although TTC7A mutation mostly affects immune and gut function, it is a multisystemic disease. Chronic pruritus has not been described yet. Aims To describe the case of a child with TTC7A mutation with chronic pruritus and the potential treatment options. Methods Case report and review of literature Results We report a child with TTC7A mutation who developed severe chronic pruritus. The child presented ileal atresia and pyloric stenosis and underwent ileo-caecal resection and pyloroplasty at birth. She required a latero-lateral anastomosis between the stomach and the duodenum because of recurring pyloric stenosis and several dilatations of her ileo-colic anastomosis. She remained dependant on parenteral nutrition for most of her caloric needs. Her immune deficiency manifested with a very low lymphocyte count and low immunoglobulins. She had pneumocystis Carinii infection at 3 months of age and was put on gammaglobulin injections and pentamidine prophylaxis. At 3 years of age, she developed severe pruritus that led to skin infection and recurrent Staphylococcus Aureus sepsis. A skin biopsy revealed eczematous dermatitis with eosinophilic infiltration. Various treatments were attempted. Replacing lipid fat emulsion by fish oil emulsion in her parenteral nutrition did not improve her symptoms. Amitryptiline, gabapentine, hydroxyzine hydrochloride and levofloxacine also failed. Corticosteroids seemed to have a mild effect. A trial of Mepolizumab (anti-IL 5) was unsuccessful. At age of 4, after a sepsis treated by vancomycin, she presented with severe bullous skin disease. Skin biopsy was compatible with linear IgA bullous dermatosis. She was put on dupilumab and systemic corticosteroids. Dupilumab inhibits signaling of both IL-4 and IL-13, two cytokines involved in inflammation that contribute to atopic dermatitis. With this combination of IV steroids and dupilumab, pruritus has improved significantly. Conclusions Our patient’s evolution suggests that some TTC7A mutation can be complicated with severe pruritus and IgA linear bullosis. Skin disease, combined with immunodeficiency and the presence of a central line can lead to life threatening sepsis. Pruritus did not respond to usual treatments but improved the combination of intravenous steroids and dupilumab suggesting a role of IL-4 and IL-13 in the pathophysiology of the pruritus associated with this disease. Hematopoietic stem cell transplantation, may be an alternative solution. Funding Agencies None
