Private Complex Inflammatory Disease Assessment in London

Some inflammatory diseases affect more than one part of the body and can be difficult to diagnose, especially when symptoms do not fit neatly into a single organ system.

Complex inflammatory conditions may include adult-onset Still’s disease, Behçet’s disease, sarcoidosis, inflammatory serositis, recurrent pericarditis, recurrent fever syndromes and other multisystem inflammatory disorders.

Symptoms may include recurrent fevers, rashes, joint pain, mouth ulcers, eye inflammation, chest pain, breathlessness, lymph node enlargement, raised inflammatory markers or unexplained systemic symptoms.

Dr Animesh Singh offers consultant-led rheumatology assessment in London for patients with suspected or established complex inflammatory disease, unexplained inflammation or diagnostic uncertainty.

The aim is to review the full clinical pattern, identify whether symptoms suggest a systemic inflammatory, autoimmune, autoinflammatory or granulomatous condition, and guide targeted investigation, treatment and multidisciplinary care where appropriate.

Dr Animesh Singh

Dr Animesh Singh is a Consultant Rheumatologist and General Internal Medicine Physician at the Royal Free Hospital, where he is Clinical Lead for Rheumatology. He offers private assessment in London for patients with suspected or established complex inflammatory disease, including adult-onset Still’s disease, Behçet’s disease, sarcoidosis, inflammatory serositis, recurrent or unexplained pericarditis, recurrent fever and multisystem inflammatory symptoms.

These conditions can be challenging because inflammation may affect joints, skin, eyes, blood vessels, lungs, lymph nodes, the heart, serosal linings or other organ systems. Symptoms can sometimes overlap with infection, malignancy, autoimmune disease, autoinflammatory disease, granulomatous disease or organ-specific conditions.

Dr Singh’s approach is to review the full clinical picture, examine carefully, interpret previous investigations in context and advise on targeted next steps. Where appropriate, assessment may involve blood tests, imaging, specialist radiology review, MRI, cardiac MRI, CT or PET-CT, as well as coordination with specialist colleagues in respiratory medicine, cardiology, ophthalmology, dermatology, infectious diseases, haematology, gastroenterology, renal medicine or other relevant specialties. The aim is to provide diagnostic clarity, identify clinically important inflammation, avoid unnecessary repeated testing where possible and guide appropriate treatment or multidisciplinary care.

Dr Singh is highly rated by patients on Doctify and Google, with more than 800 patient reviews.

Symptoms and Presentations That May Need Assessment

Complex inflammatory diseases can present in different ways, and symptoms may involve more than one organ system.

A specialist rheumatology assessment may be helpful when inflammation is persistent, unexplained or difficult to localise.

🔹 Recurrent Fever and Systemic Symptoms

Some inflammatory conditions cause systemic symptoms such as:

  • recurrent fever

  • drenching sweats

  • weight loss

  • severe fatigue

  • sore throat

  • lymph node enlargement

  • joint or muscle pain

  • raised inflammatory markers

These symptoms may require careful assessment to distinguish inflammatory disease from infection, malignancy or other medical causes.

🔹 Chest Pain, Serositis or Pericarditis

Inflammation can sometimes affect the lining around the heart or lungs.

Symptoms may include:

  • pleuritic chest pain

  • recurrent pericarditis

  • chest pain that varies with posture or breathing

  • shortness of breath

  • pleural or pericardial effusions

  • raised inflammatory markers during flares

Assessment may involve collaboration with cardiology, respiratory medicine and specialist imaging colleagues where appropriate.

🔹 Rashes, Mouth Ulcers and Eye Symptoms

Some systemic inflammatory diseases affect the skin, mouth or eyes.

Features may include:

  • recurrent mouth ulcers

  • genital ulcers

  • inflammatory eye disease

  • painful red eyes

  • skin rashes

  • nodules or tender skin lesions

  • photosensitive or unusual rashes

These symptoms can be important clues in conditions such as Behçet’s disease, sarcoidosis, lupus, vasculitis or other inflammatory disorders.

🔹 Breathlessness or Lung Inflammation

Some inflammatory diseases can involve the lungs, lymph nodes or chest.

Symptoms and findings may include:

  • breathlessness

  • cough

  • chest discomfort

  • abnormal chest X-ray or CT findings

  • enlarged lymph nodes in the chest

  • lung inflammation

  • reduced exercise tolerance

Respiratory review, CT imaging or multidisciplinary discussion may be needed in selected patients.

🔹 Raised Inflammatory Markers

Raised CRP, ESR, ferritin or other inflammatory markers can occur in many conditions.

These may include:

  • infection

  • autoimmune disease

  • autoinflammatory disease

  • sarcoidosis

  • vasculitis

  • malignancy

  • inflammatory pericarditis or serositis

  • adult-onset Still’s disease

The interpretation depends on the full clinical pattern, not the blood result alone.

🔹 Multisystem Diagnostic Uncertainty

Some patients have symptoms that do not fit neatly into one diagnosis.

This may include combinations of:

  • fever

  • rash

  • joint pain

  • chest pain

  • breathlessness

  • eye inflammation

  • mouth ulcers

  • abnormal scans

  • raised inflammatory markers

  • previous inconclusive investigations

A consultant-led rheumatology assessment can help connect the pattern and decide what further tests or specialist input are needed.

CONDITIONS

Conditions Considered

Complex inflammatory disease assessment may involve considering several possible diagnoses.

The focus is on matching symptoms, examination findings, blood tests and imaging results to the full clinical pattern.

  • Adult-Onset Still’s Disease

    Adult-onset Still’s disease is an inflammatory condition that can cause:

    • recurrent high fevers

    • joint pain or arthritis

    • sore throat

    • rash

    • raised inflammatory markers

    • markedly raised ferritin in some patients

    • swollen lymph nodes, liver or spleen involvement in some cases

    It can sometimes be difficult to distinguish from infection, malignancy or other inflammatory diseases.

    A careful assessment is important, particularly if fevers, rash and systemic inflammation are recurrent or unexplained.

  • Behçet’s Disease

    Behçet’s disease is a multisystem inflammatory condition that can affect the mouth, skin, eyes, joints, blood vessels, nervous system or gut.

    Features may include:

    • recurrent mouth ulcers

    • genital ulcers

    • inflammatory eye disease

    • skin lesions

    • joint pain or swelling

    • vascular inflammation in some patients

    • neurological or gastrointestinal involvement in some cases

    Assessment often requires careful history-taking and, where appropriate, input from ophthalmology, dermatology, neurology, gastroenterology or vascular specialists.

  • Sarcoidosis

    Sarcoidosis is a granulomatous inflammatory condition that most commonly affects the lungs and lymph nodes, but it can involve other organs.

    Features may include:

    • cough or breathlessness

    • enlarged lymph nodes in the chest

    • abnormal chest imaging

    • skin lesions

    • eye inflammation

    • joint pain

    • raised calcium levels in some patients

    • heart or neurological involvement in selected cases

    Assessment may involve respiratory medicine, ophthalmology, cardiology, neurology or specialist imaging depending on the organs involved.

  • Inflammatory Serositis and Recurrent Pericarditis

    Serositis refers to inflammation of the lining around organs, such as the pleura around the lungs or the pericardium around the heart.

    Inflammatory serositis or recurrent pericarditis may cause:

    • chest pain

    • pain worse with breathing or posture

    • shortness of breath

    • pleural or pericardial effusion

    • recurrent inflammatory flares

    • raised inflammatory markers

    • abnormal echocardiogram, cardiac MRI or CT findings in selected cases

    Rheumatology assessment can help consider whether symptoms suggest an autoimmune, autoinflammatory or systemic inflammatory cause, alongside cardiology or respiratory input.

  • Autoinflammatory and Recurrent Fever Syndromes

    Some patients have recurrent inflammatory episodes driven by autoinflammatory mechanisms.

    Symptoms may include:

    • recurrent fever

    • rash

    • abdominal pain

    • chest pain

    • joint pain

    • raised inflammatory markers during attacks

    • family history or early-life symptoms in some cases

    These conditions are uncommon, and assessment may require specialist investigation or referral depending on the clinical pattern.

  • Other Multisystem Inflammatory Conditions

    Other inflammatory diseases can sometimes mimic or overlap with adult-onset Still’s disease, Behçet’s disease, sarcoidosis or inflammatory serositis.

    These may include:

    • lupus or connective tissue disease

    • vasculitis

    • inflammatory arthritis

    • infection-related inflammation

    • immune-mediated lung or cardiac inflammation

    • haematological or malignant causes of inflammation

    • drug-related inflammatory reactions

    Assessment focuses on identifying the most likely explanation and deciding which investigations or specialist colleagues should be involved.

Assessment

How Complex Inflammatory Disease Is Assessed

Assessment begins by reviewing the full clinical pattern, including symptoms, examination findings, previous blood tests, imaging results, specialist opinions and response to previous treatments.

Complex inflammatory diseases often require careful interpretation because symptoms may overlap with infection, malignancy, autoimmune disease, autoinflammatory disease, granulomatous disease or organ-specific conditions.

Treatment

Treatment, Investigation and Multidisciplinary Care

Treatment depends on the diagnosis, organ systems involved, severity of inflammation, previous treatment response and the balance of risks and benefits.

Because this page covers several different inflammatory diseases, treatment is best considered in broad categories rather than as a single pathway.

Key Message

Complex inflammatory diseases often require careful diagnosis before treatment decisions are made.

Treatment may involve monitoring, anti-inflammatory medication, corticosteroids, steroid-sparing immunosuppression, biologic therapy or organ-specific specialist care, depending on the diagnosis and severity.

The aim is to identify clinically important inflammation, involve the right specialists and develop a targeted plan rather than applying a one-size-fits-all approach.
