Correlation between nail psoriasis severity index score with quality of life in nail psoriasis

Abstract

Background: Psoriasis is a recurring chronic inflammatory disease, which can involve the skin, nails and joints. Nail psoriasis occurred in 50% of psoriasis patients. Nail psoriasis can interfere with the quality of life (QoL) due to its physical, mental, and social impacts. To determine the correlation between Nail Psoriasis Severity Index (NAPSI) score and QoL in nail psoriasis patients.Methods: This was a correlative analytical study with a cross-sectional approach that involved nail psoriasis subjects aged ≥18 years. Data accessed from the recording of basic data. The examination of subjects included an assessment of NAPSI scores and the Nail Psoriasis Quality of Life (NPQ10) questionnaire. Statistical analyses were performed using Pearson’s correlation coefficients, with P<0.05 was considered statistically significant.Results: A total of 26 subjects with nail psoriasis, with the highest proportion, were female (57.7%), age group of 48–57 years (34.6%), duration of psoriasis >5 years (76.9%), NAPSI score 81-100 (30.8%), the mean NAPSI score was 89.42±32.01, and the mean NPQ10 score was 6.96±3.30. There was a significant moderate positive correlation between the NAPSI score and QoL (r=0.632, p=0.001).Conclusion: The higher the NAPSI scores, the worse the quality of life for nail psoriasis patients.
