Persistent joint pain, swelling, stiffness or unexplained symptoms involving several parts of the body may require assessment beyond general musculoskeletal care. Rheumatologists assess conditions affecting the joints, muscles, connective tissues and immune system, including inflammatory arthritis and systemic autoimmune diseases.
Choosing a rheumatologist in Singapore may involve considering the doctor’s qualifications, clinical interests, scope of services, consultation process and ability to coordinate care where several organ systems are affected.
Dr Anindita Santosa is the Founding Medical Director of Aaria Rheumatology and practises as a Consultant Rheumatologist, Clinical Immunologist and Allergist. Her clinical scope includes autoimmune diseases, inflammatory arthritis, allergic disorders, immune dysregulation and adult immunodeficiency.

Dr Santosa’s work covers rheumatology, clinical immunology and allergy. This combined scope may be relevant when symptoms overlap across inflammatory, autoimmune, allergic and immune-related conditions.
The assessment or treatment recommended depends on the patient’s symptoms, medical history, examination findings and available investigation results.
Inflammatory arthritis occurs when inflammation affects one or several joints. Symptoms may include swelling, warmth, stiffness, pain and reduced movement.
Conditions assessed at Aaria Rheumatology include:
Rheumatoid arthritis
Psoriatic arthritis
Axial spondyloarthritis
Peripheral spondyloarthritis
Suspected early inflammatory arthritis
Some inflammatory joint diseases may also produce symptoms outside the joints. The areas affected and pattern of symptoms can therefore form part of the diagnostic assessment.
Systemic autoimmune diseases develop when immune activity affects the body’s own tissues. Depending on the condition, the joints, skin, muscles, blood vessels, lungs, kidneys or other organs may be involved.
Conditions within the clinic’s stated scope include:
Systemic lupus erythematosus
Sjögren’s syndrome
Systemic sclerosis, also known as scleroderma
Idiopathic inflammatory myopathies
Mixed connective tissue disease
Undifferentiated connective tissue disease
Autoimmune overlap syndromes
Patients with multi-system conditions may require monitoring by several medical disciplines. The specialists involved will depend on the diagnosis and organs affected.
The clinic also assesses gout, hyperuricaemia and calcium pyrophosphate deposition disease.
Gout can cause episodes of joint pain, swelling and inflammation. Assessment may involve reviewing the pattern of attacks, medication history, blood test results and related health factors.
The treatment plan will depend on the diagnosis, frequency of symptoms and the patient’s medical circumstances.
Vasculitis refers to a group of disorders involving inflammation of the blood vessels. The symptoms can vary according to the type of vasculitis and the organs affected.
Conditions listed within the clinic’s scope include:
ANCA-associated vasculitis
Large-vessel vasculitis
Medium-vessel vasculitis
Behçet’s disease
Autoinflammatory disorders
Other immune-mediated rheumatic conditions
Not every joint or muscle condition is caused by systemic inflammation. Rheumatology assessment may also cover:
Osteoarthritis
Soft tissue rheumatism
Chronic widespread pain
Fibromyalgia
Joint hypermobility syndromes
Assessment can help distinguish inflammatory disease from degenerative, mechanical or non-inflammatory causes of pain.
Dr Santosa has a stated special interest in Clinical Immunology and Allergy and completed formal subspecialty training in these areas in 2023.
Clinical immunology services at Aaria Rheumatology include:
Evaluation of immune-mediated inflammatory diseases
Assessment of complex immune dysregulation syndromes
Primary immunodeficiency assessment
Secondary immunodeficiency assessment
Evaluation of recurrent infections
Autoimmune serology and immune investigations
Interpretation of complex or inconclusive immune test results
Recurrent infections or unusual investigation findings do not necessarily confirm an immune disorder. A clinical assessment is required to determine whether an immune evaluation is appropriate.
Allergy services listed by the clinic include assessment of:
Suspected drug hypersensitivity
Possible vaccine allergy
Allergic rhinitis
Allergic conjunctivitis
Urticaria
Angioedema
Food allergies
Environmental allergies
Conditions involving overlapping allergic and immune-mediated features
Care may involve reviewing the suspected trigger, timing and pattern of symptoms, previous reactions and relevant medical history. Risk assessment and continuing management may be discussed where applicable.
The treatment considered for a rheumatic or immune-related condition depends on the diagnosis, disease activity, previous response to treatment and the patient’s wider health circumstances.
Medication categories available within the clinic’s stated services include:
Conventional synthetic disease-modifying antirheumatic drugs
Biologic therapies
Targeted synthetic therapies, including JAK inhibitors
Immunomodulatory medicines
Immunosuppressive medicines
The potential benefits, risks and alternatives of treatment should be discussed before medication is started or changed.
Procedural services include:
Joint injections
Soft tissue injections
Musculoskeletal assessments
Guided interventions
Nailfold capillaroscopy
Infusion and therapy planning where applicable
Nailfold capillaroscopy examines the small blood vessels around the nail bed and may form part of the assessment for certain connective tissue or vascular conditions.
Patients looking for a rheumatologist may wish to understand how consultations, investigations and continued care are structured. Dr Santosa’s practice covers several aspects of rheumatic and immune-related disease management.
Symptoms do not always fall within a single medical category. Joint inflammation may occur alongside skin, respiratory, allergic or immune-related concerns.
Dr Santosa’s scope across rheumatology, clinical immunology and allergy allows these overlapping symptoms to be considered within the same specialist practice. Referral to another discipline may still be required when a condition falls outside this scope or affects an organ requiring separate specialist management.
An initial consultation begins with a discussion of symptoms, medical history, previous investigations and earlier treatments. The doctor may also ask how the condition affects work, mobility, family responsibilities and daily activities.
A focused physical examination may follow, based on the patient’s symptoms and concerns.
Patients may bring available medical information such as:
Consultation notes or clinic letters
Hospital discharge summaries
Blood test results
X-ray, ultrasound, CT or MRI reports
Biopsy or pathology findings
A current medication and supplement list
Information about treatments previously stopped
A written summary of symptoms
Questions they would like to discuss
Pregnancy plans, vaccinations, recent infections, family history and relevant life events may also be discussed where applicable.
A confirmed diagnosis may not always be possible during the initial consultation. Autoimmune and immunological diseases can produce overlapping symptoms, and some conditions become clearer through observation and follow-up.
Where applicable, the consultation may explain:
The working diagnosis
Other conditions being considered
Findings that are currently understood
Areas that remain uncertain
Investigations that may be useful
Possible treatment options
Follow-up arrangements
Additional tests may be suggested when they are relevant to diagnosis or management.
Patients may be involved in discussions concerning treatment options, potential benefits, risks and alternatives. The consultation may also cover medication use, vaccination planning, lifestyle considerations and symptoms to monitor between appointments.
This process can help patients understand why a particular investigation, treatment or monitoring plan is being considered.
Systemic autoimmune diseases can affect several parts of the body. Aaria Rheumatology lists collaboration with professionals in:
Obstetrics
Nephrology
Dermatology
Respiratory medicine
Neurology
Allied health services
The care team will depend on the patient’s diagnosis and the organs or functions affected.
Some rheumatic diseases follow a chronic or fluctuating course. Continued care may involve:
Monitoring symptoms and disease activity
Reviewing investigation results
Assessing medication tolerance
Revising treatment where clinically indicated
Discussing possible flare symptoms
Reviewing mobility and daily function
Considering rehabilitation and lifestyle support
Providing disease and medication education
Follow-up intervals vary according to the condition, treatment plan and clinical findings.
Dr Santosa is involved in clinical education, academic writing and professional development. Her clinic profile also lists involvement with the Singapore Society of Rheumatology and the Asia Pacific League of Associations for Rheumatology.
She is involved with the Lupus Association Singapore in patient education, advocacy and awareness relating to systemic autoimmune diseases.
Autoimmune and inflammatory diseases may require specific planning during pregnancy, breastfeeding, fertility treatment, contraception and menopause.
Services available at Aaria Rheumatology include:
Autoimmune disease management during pregnancy
Care planning during breastfeeding
Fertility discussions
Contraception counselling
Medication counselling
Menopause-related considerations
Disease management across different life stages
These discussions can help patients understand how their condition and medication plan relate to reproductive health and life-stage changes.
A rheumatology consultation may be considered when symptoms persist, recur or begin to affect normal activities.
Reasons for seeking an assessment can include:
Persistent joint pain
Joint swelling, warmth or redness
Prolonged stiffness after waking
Reduced joint movement
Recurrent gout attacks
Chronic back pain accompanied by stiffness
Unexplained fatigue with joint, skin or systemic symptoms
Persistent dry eyes or dry mouth
Recurring fever or rashes with musculoskeletal symptoms
Blood tests suggesting inflammation or autoimmune activity
Symptoms affecting several organ systems
A suspected or confirmed autoimmune condition
Recurrent infections requiring an immune evaluation
A suspected medicine, vaccine, food or environmental allergy
The need for diagnostic clarification or a treatment review
These symptoms can have several possible causes and do not confirm a rheumatic or immunological disorder. A medical assessment is required to determine whether specialist investigations or treatment are appropriate.
The suitability of a rheumatologist depends on the condition being assessed, the doctor’s clinical scope and the patient’s individual needs. Practical factors such as clinic location, communication preferences, continued monitoring and coordination with other specialists may also be relevant.
Dr Anindita Santosa practises across rheumatology, clinical immunology and allergy at Aaria Rheumatology. Her stated interests include inflammatory arthritis, systemic autoimmune connective tissue diseases, allergic disorders, immune dysregulation, adult immunodeficiency, osteoporosis and women’s health.
Patients can contact Aaria Rheumatology to enquire whether their symptoms or condition fall within the clinic’s scope before arranging a consultation.
