Background: Omalizumab is approved in the UK as add-on treatment for chronic spontaneous urticaria (CSU) in patients with inadequate response to H1-antihistamines. Ciclosporin is an established but unlicensed 3rd line option for CSU. Two parallel retrospective observational studies were conducted to describe outcomes of treatment and adverse events with omalizumab or ciclosporin for CSU treatment.Methods: Data from UK specialist centres prescribing omalizumab (five centres) or ciclosporin (three centres) in CSU patients were collected from hospital records by clinical staff and pooled for analysis.Results: Forty-six patients prescribed omalizumab and 72 patients prescribed ciclosporin were included. Twenty-two (48%) omalizumab-treated patients had paired Urticaria Activity Scores (UAS7), showing a 25.4 point improvement during treatment (P < 0.0001). Paired Dermatology Life Quality Index (DLQI) was available in 28 (61%) omalizumab-treated and 17 (24%) ciclosporin-treated patients. At least a 75% improvement in DLQI score was observed in 79% of omalizumab-treated and 41% of ciclosporin-treated patients, and 65% of omalizumab-treated patients had complete resolution of their quality-of-life impairment (DLQI 0–1) versus 21% of ciclosporin-treated patients. Clinician comments reported symptom clearance in 15/36 (42%) omalizumab-treated and 10/60 (17%) ciclosporin-treated patients. Proportions of patients with adverse events were similar but those for omalizumab resembled CSU symptoms, making causality assignment difficult, whereas those for ciclosporin were consistent with its known adverse effect profile.Conclusions: Validated patient-reported measures of disease severity and quality of life should be used routinely in CSU management. Based on clinician comments and DLQI scores, symptoms and quality of life showed a greater improvement in the omalizumab-treated cohort than in the ciclosporin-treated cohort.

Background Chronic palmoplantar pustulosis (PPP) is a chronic inflammatory skin condition characterised by crops of sterile pustules (yellow pus spots) on the palms and soles which erupt repeatedly over months or years. The affected areas tend to become red and scaly; cracks may form and these are often painful. Many different treatments have been used for palmoplantar pustulosis but none is generally accepted as being reliably effective. Objectives To assess the effects of treatments for palmoplantar pustulosis, both in reducing disease severity and in maintaining remission once achieved. Search methods We searched the Cochrane Skin Group Specialised Register (January 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2003), MEDLINE (1966 to February 2003), EMBASE (1988 to February 2003). We also cross-checked with the Salford Database of Psoriasis Trials and reference lists of articles. We also contacted authors included trials, members of the Cochrane Skin Group and dermatologists interested in psoriasis. Selection criteria Any randomised controlled trial in which patients with chronic palmoplantar pustulosis were randomised to receive one or more interventions. Data collection and analysis At least two reviewers independently assessed trial eligibility and quality. Study authors were contacted for additional information. Adverse effects information was collected from the trials. Main results Twenty-three trials involving 724 people were included. There is evidence supporting the use of systemic retinoids (improvement rate difference 44%, 95 CI 28 to 59%), oral PUVA (improvement rate difference 44%, 95 CI 26 to 62%). However, a combination of PUVA and retinoids is better than the individual treatments. The use of topical steroid under hydrocolloid occlusion is beneficial. It would also appear that low dose ciclosporin, tetracycline antibiotics and Grenz Ray Therapy may be useful in treating PPP. Colchicine has a lot of side effects and it is unclear if it is effective and neither was topical PUVA (rate difference of 0.00, 95% CI -0.04 to +0.04). There is no evidence to suggest that short-term treatment with hydroxycarbamide (hydroxyurea) is effective. Authors' conclusions Many different interventions were reported to produce "improvement" in PPP. There is, however, no standardised method for assessing response to treatment, and reductions in pustule counts or other empirical semi-quantitative scoring systems may be of little relevance to the patient. This review has shown that the ideal treatment for PPP remains elusive and that the standards of study design and reporting need to be improved to inform patients and those treating them of the relative merits of the many treatments available to them.
