Lupus (SLE) in Nigeria

A complex autoimmune disease disproportionately affecting Nigerian women

Systemic lupus erythematosus (SLE), commonly called lupus, is a chronic autoimmune disease in which the immune system attacks healthy tissue throughout the body — particularly the skin, joints, kidneys, brain, and heart. It affects women 9 times more frequently than men, with peak onset between ages 15–45. In Nigeria, lupus is significantly underdiagnosed — partly due to limited rheumatology services (fewer than 50 consultant rheumatologists in the country) and partly due to overlap of lupus symptoms with more common conditions like malaria, typhoid, and anaemia. Delayed diagnosis leads to severe organ damage, particularly lupus nephritis (kidney disease).

Signs and Symptoms

✓ Butterfly rash (malar rash): red rash across the cheeks and bridge of the nose

✓ Photosensitivity: skin rashes or flares triggered by sun exposure

✓ Joint pain and swelling — multiple joints, usually symmetric, without deformity

✓ Persistent fatigue disproportionate to activity

✓ Hair loss (alopecia) — diffuse thinning or patchy

✓ Oral ulcers — painless ulcers on the roof of the mouth or inside cheeks

✓ Fever without clear infection source

✓ Raynaud's phenomenon: fingers turn white, then blue, then red in the cold

✓ Serositis: pleuritis (chest pain with breathing) or pericarditis (central chest pain)

✓ Kidney involvement: frothy urine, ankle oedema, high blood pressure, reduced urine output

✓ Neuropsychiatric lupus: seizures, psychosis, cognitive impairment, headaches

Risk Factors

Female sex: 9:1 female to male ratio
Age 15–45 (reproductive years — oestrogen influence)
African ancestry: SLE in Black African women is typically more severe and more likely to involve kidneys
Family history of lupus or other autoimmune disease
UV light exposure (sun triggers flares)
Infections: EBV, CMV may trigger lupus in genetically susceptible individuals
Medications that can cause drug-induced lupus: hydralazine, procainamide, isoniazid, minocycline

When to Seek Help

Kidney symptoms: frothy urine, ankle swelling, high BPLupus nephritis is the leading cause of serious organ damage — early treatment prevents dialysis

Neurological symptoms: seizures, confusion, stroke-like symptomsNeuropsychiatric lupus is a medical emergency

Chest pain with breathing difficultyPleuritis or pericarditis — may be lupus flare or blood clot (antiphospholipid syndrome — common in SLE)

Severe fatigue + rash + joint painThe triad of lupus — seek rheumatology opinion rather than treating as malaria or arthritis alone

Known lupus with new feverInfection must be excluded in immunosuppressed lupus patients before treating as a flare

Tests & Diagnosis

🧪 ANA (antinuclear antibody)

Positive in > 95% of SLE cases — very sensitive but not specific (also positive in other conditions and 5% of healthy people)

🧪 Anti-dsDNA antibody

More specific for SLE — levels correlate with disease activity, especially kidney involvement

🧪 Anti-Sm antibody

Highly specific for SLE — present in about 25% of Nigerian patients

🧪 Complement levels (C3, C4)

Low C3 and C4 indicate active lupus (complement being consumed in immune complexes)

🧪 Full blood count

Anaemia, low white cells (leucopoenia), low platelets (thrombocytopaenia) — all hallmarks of SLE

🧪 Urinalysis and renal function

Proteinuria, red cells in urine, rising creatinine — signs of lupus nephritis. A 24-hour urine protein > 0.5g/day is significant

🧪 Kidney biopsy

Confirms type of lupus nephritis (Class I–VI) and guides intensity of immunosuppressive treatment

🧪 Antiphospholipid antibodies

Lupus anticoagulant, anti-cardiolipin antibodies — present in 30–40% of SLE, causes blood clots and recurrent miscarriage

Treatment Options

Hydroxychloroquine (Plaquenil)

The cornerstone of SLE treatment — reduces flares, organ damage, and mortality. 200–400mg daily. Takes 3–6 months for full effect. Requires annual eye check (very rare retinopathy). Should be on this medication lifelong for most patients

NSAIDs

For joint pain and mild serositis. Use with caution — monitor kidneys

Corticosteroids (prednisolone)

Used for flares — high dose for severe organ involvement, tapered once controlled. Side effects with long-term use: weight gain, diabetes, osteoporosis, infection risk

Immunosuppressants for organ-threatening disease

Azathioprine (maintenance), mycophenolate mofetil (nephritis), or cyclophosphamide (severe nephritis/neuropsychiatric) — available at tertiary hospitals in Nigeria

Belimumab

Biologic agent specifically targeting lupus pathogenesis. Available in Nigeria but expensive — limited access

Sun protection

SPF 50+ sunscreen daily, sun-protective clothing, avoiding peak sun hours (10am–4pm) — UV exposure is a major flare trigger in Nigeria's climate

Contraception in lupus

Oestrogen-containing contraceptives may worsen lupus. Progestogen-only methods or IUD preferred

Frequently Asked Questions

Can lupus be cured?

There is currently no cure for SLE. However, with proper treatment most people achieve remission — periods where the disease is inactive and causes no symptoms. The goal is to suppress the immune attack, prevent organ damage, and maintain quality of life long-term.

Does lupus affect pregnancy?

Yes — lupus increases the risk of miscarriage, preterm birth, preeclampsia, and lupus flares during pregnancy. However, with careful planning (conceive during remission), specialist care, and appropriate medications (hydroxychloroquine is continued in pregnancy), most women with SLE can have successful pregnancies.

Is lupus common in Nigeria?

Lupus is underdiagnosed in Nigeria, not uncommon. Studies suggest a prevalence of 20–150 per 100,000 in Nigerian populations — comparable to other Sub-Saharan African countries. It is frequently misdiagnosed as malaria, rheumatic fever, or anaemia due to overlapping symptoms and limited rheumatology services.

Where can I see a rheumatologist in Nigeria?

Rheumatology services are available at UCH Ibadan, LUTH Lagos, UNTH Enugu, Aminu Kano Teaching Hospital, and a small number of other tertiary hospitals. Private rheumatology practice is growing in Lagos and Abuja. Waiting lists are long — early referral is important.
