Severity assessment
As per DDG/DGRh/GKJR 2021 guidelines:
Consider using the CLASI or revised CLASI to assess disease activity and intensity in patients with CLE.
Consider using the DLQI or Skindex-29 (skin-specific methods for assessing the QoL) to assess the QoL in patients with CLE.

Diagnostic investigations

History and physical examination: as per BAD 2021 guidelines, evaluate for SLE by history, examination and targeted laboratory investigations in patients with CLE.

Diagnostic procedures

Biopsy and histopathology: as per DDG/DGRh/GKJR 2021 guidelines, perform lesional biopsy for histological confirmation of a clinical diagnosis of CLE, while omitting in cases of butterfly rash or mucosal lesions.

Nonpharmacologic interventions

Lifestyle modifications: as per BAD 2021 guidelines, counsel patients with CLE about the importance of lifestyle changes on disease activity and treatment response, such as smoking cessation and the need for a range of photoprotective measures, including the use of a broad-spectrum sunscreen.

Therapeutic procedures

Intralesional corticosteroids: as per BAD 2021 guidelines, consider administering intralesional triamcinolone (0.1 mL/cm² field, starting at 2.5-5 mg/mL for sites at higher risk of atrophy including the face and 10 mg/mL for other sites) as a local treatment option in patients with localized DLE or as an adjunctive therapy for persistent lesions.

Patient education

General counseling
As per BAD 2021 guidelines:
Offer obtaining a pregnancy test in female patients of child-bearing potential before initiating methotrexate, mycophenolate mofetil, acitretin, rituximab, belimumab, cyclophosphamide, thalidomide or lenalidomide therapy. Counsel them regarding the risk of teratogenicity, advise pregnancy prevention and instigate the pregnancy prevention program.
Advise using reliable contraception as a precautionary measure in sexually active male patients during methotrexate, mycophenolate mofetil, thalidomide and lenalidomide therapy, during dose interruption (where applicable) and for periods of time following the cessation of treatment.

Preventative measures

Routine immunizations: as per ACR 2023 guidelines, consider offering high-dose or adjuvanted influenza vaccination, rather than regular-dose influenza vaccination, in ≥ 65 years old patients with rheumatic or musculoskeletal diseases and in 18-65 years old patients with rheumatic or musculoskeletal diseases on immunosuppressive medications.
