“…In two of nine patients reported, remission of CSU was seen after HCV‐specific treatment and improvement (Table ). In 16 patients with CHB, specific antiviral therapy did not reduce CSU disease activity . This is in line with the assessment by Kulthanan et al that the treatment of chronic viral diseases including hepatitis usually does not result in the remission of CSU or the improvement of its symptoms.…”

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.

“…Some studies report that urticaria may disappear in the patients with parasitic infection after specific treatment for the parasite [14]. In a study, 16 CSU patients with IPI were treated with anti-parasitic therapy and 43.7% of them had regression in urticaria symptoms [23].…”

Introduction: Chronic spontaneous urticaria (CSU) which develops without a known stimulation is defined as the occurrence of spontaneous wheals, angioedema or both for longer than six weeks. Infections, autoimmunity, food intolerance and internal parasitic infections are supposed to be underlying causes of CSU. The aim of this study was to evaluate the intestinal parasites in children and adult patients diagnosed as CSU, to determine the frequency of parasites in chronic urticaria, and to compare these patients with healthy demographic control groups. Methodology: Seventy six children and 38 adult patients with CSU were examined in terms of parasitic infections. The patients whom parasites were detected received anti-parasitic therapy and the improvements in CSU symptoms were evaluated. Stool samples were examined with direct microscopic examination (native-lugol), stool concentration and trichrome staining methods. Results: In pediatric patient group, 18.4% (n = 14) of the stool samples were positive for Blastocystis sp., 2.6% (n = 2), Dientamoeba fragilis and 1.3% (n = 1), Giardia duodenalis. In adult patient group, Blastocystis sp. was detected in 18.4% (n = 7) of the stool samples. Anti-parasitic therapy yielded substantial improvement in urticaria symptoms in 57.1% of pediatric and 60.0% of adult patients. Conclusions: Blastocystis sp. and D. fragilis may play a role in chronic urticaria which seriously disrupts the patient's quality of life. Parasitic infections should not be neglected in patients with cutaneous manifestations.

“…For example, Anisakis simplex , a sea fish nematode, has only been discussed as a possible cause of recurrent acute spontaneous urticaria in areas of the world where uncooked fish is eaten frequently . The relevance of H. pylori , dental or ear, nose and throat infections also appears to vary between patient groups . More research is needed to make definitive recommendations regarding the role of infection in urticaria.…”

This evidence- and consensus-based guideline was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. The conference was held on 1 December 2016. It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-founded network of excellence, the Global Allergy and Asthma European Network (GA²LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO) with the participation of 48 delegates of 42 national and international societies. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell-driven disease, presenting with wheals, angioedema, or both. The lifetime prevalence for acute urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria are disabling, impair quality of life and affect performance at work and school. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms. In addition, it outlines evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria.
