Clinical Remission of Chronic Spontaneous Urticaria (CSU): A Targeted Literature Review

Table 4 Proportions of patients who had not entered remission at the different time points (months)

Study^a	Included patients	6	12	24	36	48	60	120	300
Beltrani, 2002 [6]	Persistent urticaria patients	50%	–	–	30%	–	10%	–	≤ 8%
Van der Valk, 2002 [10]	CSU patients with or without angioedema	–	–	–	–	–	66%	51%	–
Toubi, 2004 [14]	Mild to severe CSU patients	94%	75%	52%	43%	–	14%	–	–
Nebiolo, 2009 [9]	All patients	–	–	74%	–	–	54%	–	–
Kim, 2018 [13]	All patients	–	78%	67%	61%	57%	55%	–	–

For Toubi et al. [14] and Nebiolo et al. [9], values are presented as reported in citations, while for Beltrani et al. [6], Van der Valk et al. [10] and Kim et al. [13] values were calculated (assuming overall population constituted 100%, proportion not entering remission were calculated after subtracting the patients who had remitted in the overall population). The studies of Kozel et al. [7], Kulthanan et al. [8], Boonpiyathad et al. [11] and Chuamanochan et al. [12] were not included due to the limited number of data points which made them inappropriate for curve fitting to predict remission
