Which of the following is NOT a diagnostic criterion for SLE?

The presence of a chronic cough is not recognized as a diagnostic criterion for systemic lupus erythematosus (SLE). Diagnostic criteria for SLE include manifestations such as a malar rash, which presents as a butterfly-shaped rash across the cheeks and nose, as well as photosensitivity, where exposure to sunlight can trigger or exacerbate skin lesions. Additionally, renal disorders that involve proteinuria are indicative of lupus nephritis, a common and significant complication of SLE.

In contrast, while a chronic cough can occur in various medical conditions, it is not specific to SLE and does not fall under the established criteria for making a diagnosis of this particular autoimmune disease. Understanding the specific criteria helps healthcare providers accurately identify SLE and differentiate it from other conditions presenting with similar symptoms.
