Clinical and laboratory assessment for the inflammation role in chronic spontaneous urticaria: A clinical study

Chronic spontaneous urticaria (CSU) is triggered by unknown causes. We would like to explore the possible effect of hemogram parameters and several biochemical markers on CSU presence and also the severity of the disease. We also aimed to discuss the relationship between CSU and inflammation associated with these values. The study was planned prospectively. We selected patients already diagnosed with CSU who applied to the dermatology outpatient clinic and healthy controls. The patients and the healthy controls were tested for complete blood count, neutrophil/lymphocytes ratio and platelets/lymphocytes ratio, erythrocyte sedimentation rate, C-reactive protein, serum albumin and total bilirubin and indirect bilirubin levels. Urticaria activity score over 7 days (UAS-7) was calculated for the CSU patients. Forty patients with CSU and 55 healthy subjects were included in the study. Mean white blood cell (WBC) count is 8.37 ± 2.14 in the patients' group and 7.41 ± 2.01 in the healthy subjects group. Mean neutrophil (NEU) count is 4.88 ± 1.65 in the patients' group and 4.19 ± 1.39 in the healthy subjects group. Mean platelets (PLT) count is 308.48 ± 88.32 in the patients' group and 268.65 ± 64.80 in the healthy subjects group. We also detected positive correlations between UAS-7 score-WBC counts and UAS-7 score-NEU counts. Future studies are needed to investigate this possible relationship and confirm these results.

Comorbidity of viral hepatitis and chronic spontaneous urticaria: A systematic review

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.
