Table 3.

The treatment delay, frequency, length and efficiency of the glucocorticoid therapy and the number of nephritis relapses. The data are presented separately for patients with isolated tubulointerstitial nephritis, patients with uveitis and chronic uveitis

	TIN n = 19	TINU n = 12	TINU with chronic uveitis n = 21	p value
Corticosteroid therapy, n (%)	18 (100)	10 (83)	17 (81)	0.15
Treatment delay, days	31 (11–173)	41 (13–190)	38 (18–190)*	0.16
Duration of medication, months	7.5 (2–24)	2 (0.1–12)	6.5 (2–66) n = 15	0.01
Time to normal creatinine, months	1 (1–12)*	1 (0–3)#	2 (0–36)	0.06
Time to normal ESR, months	2 (1–6) n = 16	1 (0–6)#	1 (0–11)	0.67
Nephritis relapse, n (%)	5 (26)	1 (8)	6 (29)*	0.40

Data is presented as n (%) or median (range). Analyses performed by Chi-squared or Kruskal–Wallis test, as appropriate. A two-tailed p value is reported. Treatment delay was defined as the time from onset of symptoms to the beginning of cortisone treatment. ESR, erythrocyte sedimentation rate
