Nail changes involving fingernails and toenails were documented as new-onset or pre-existing changes. Disease status, hematological and biochemical tests, inflammatory markers, treatment administered and outcomes were also recorded. The frequency of changes in fingernails and toenails were statistically compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The red half-moon sign (32.5%) and nail bed erythema (34.8%) were the commonest changes seen in fingernails; while apparent leukonychia (46.5%) and distal brown discoloration (51.1%) were commonest changes in toenails. The difference in frequency of changes seen between fingernails and toenails was statistically significant (p &lt; 0.05). Nail changes correlated with systemic involvement in these patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Limitations:<\/jats:title>\n                    <jats:p>Single-center evaluation in a limited number of patients, without using augmented examination techniques like onychoscopy, nail fold capillaroscopy, or fluoroscence.
