RESULTS
Of the 101 patients included in the study, 57 (56.4%) were female and 44 (43.4%) were male. The ages of the patients ranged from 18 to 77, and the mean age was 49.72 ± 16.37. 64 (64%). Of the 100 patients in the control group, 64 (64%) were female and 36 (36%) were male. The ages of the control group ranged from 18 to 78 years, with a mean age of 49.16 ± 17.61. There was no significant difference between the patient group and the control group in terms of age and gender (p = 0.83).
Thirty five (34.7%) of the zona zoster patients applied to the outpatient clinic in winter, 5 (5%) in spring, 30 (29.7%) in summer and 31 (30.7%) in autumn. Zona zoster developed in the thoracic region in 42 patients, in the lumbar region in 31 patients, in the ophthalmic region in 7 patients, in the leg region in 10 patients, in the arm region in 2 patients, in the cervical region in 8 patients, and in the mandibular region in 1 patient (Table 1).
25-OH vitamin D levels were calculated as <20 µg / L deficiency, 21-29 µg / L insufficiency and> 30 µg / L sufficient dose. The 25-OH vitamin D levels of the patients ranged from 2.37 to 32.98 µg / L and the mean value was 14.25 ± 7.20 µg / L. In the patient group, the number of patients with deficiency of 25-OH vitamin D level was 82 (81.2%), the number of patients with insufficient level was 15 (14.9%), and the number of patients with sufficient level was 4 (4%). In the control group, 25-OH vitamin D levels ranged between 10.3 and 44.25 µg / L, and the mean value was 24.9 ± 6.24 µg / L. In the control group, the number of individuals with 25-OH vitamin D deficiency was 20 (20%), the number of individuals with insufficient level was 59 (59%), and the number of individuals with sufficient level was 21 (21%). 25-OH vitamin D levels in the patient group were significantly lower than the levels in the control group (p <0.001) (Table 2).
