A cross-cutting clinical approach
An internal medicine approach connects organ involvement, chronology and targeted findings. It distinguishes diagnostic evidence, inflammatory activity, established damage and treatment complications before escalating immunomodulation.
01 · Build a clinical phenotype
Establish onset, flares, general symptoms and cutaneous, joint, vascular, muscular or visceral features. Look for coherent associations and objective findings rather than adding nonspecific symptoms. The Systemic lupus, Sjögren disease, Systemic sclerosis and Vasculitis courses then develop particular hypotheses. Infection, drug toxicity or another disease can produce a similar presentation.
[1][2][3]02 · Request targeted evidence
Select tests according to clinical probability and the suspected organ: urinalysis and kidney function, blood count, inflammatory markers, targeted immunology or specialist assessment. A single negative result does not exclude all diseases; an isolated positive result does not establish them. Persistent synovitis warrants specialist assessment even with negative serology. Check method, context and clinical agreement before interpreting an abnormality.
[1][2]03 · Separate activity, urgency and damage
New breathlessness, neurological deficit, visual loss, kidney deterioration or major cytopenias requires prompt appropriate assessment. In an already treated patient, compare new findings with baseline and particularly consider infection. Persistent pain or fatigue may reflect damage or comorbidity; it does not automatically justify stronger immunosuppression.
[2][3]04 · Organise continuity of care
Agree on a clinical target and monitoring plan with the patient, coordinating specialties according to organ involvement. Include cardiovascular prevention, infection assessment, individual vaccination planning and discussion of pregnancy plans where relevant. Document treatment, adverse effects and symptoms requiring reassessment. Regularly reconsider benefit and risk instead of continuing a regimen that has become unsuitable.

FICTIONAL SITUATION · WITHOUT A SCORE
Fictional situation: someone with a connective tissue disease develops increased fatigue and recent fever. They assume this must be a flare.
What question should precede treatment escalation?
Read the reasoning
Determine whether this reflects inflammatory activity, infection, toxicity or another cause. Examine the patient, assess severity and target tests to symptoms and treatment. An established autoimmune diagnosis does not remove the need for differential diagnosis. Organ threat requires urgent specialist coordination alongside infection assessment.
