BIRTH HISTORY
Antenatal: Not fully documented — no known maternal illness specifically stated. Mother has asthma on MDI (pre-existing).
Natal: Born at term, 37 weeks gestation, via spontaneous vaginal delivery (to confirm). Asymmetrical SGA, birth weight 1.5 kg.
Postnatal/Neonatal:
- Admitted NICU at birth for: resolved sepsis (thrombocytopaenia, pancytopaenia, hypoglycaemia) and resolved neonatal jaundice with conjugated hyperbilirubinaemia.
- Duration of NICU stay not documented — to clarify.
- Treated with antibiotics and phototherapy (to confirm).
FEEDING / DIETARY HISTORY
Currently tolerating adult diet. No feeding difficulties. Orally well on admission.
IMMUNISATION HISTORY
Up to date as per national EPI schedule.
DEVELOPMENTAL HISTORY
| Domain | Milestone |
|---|
| Gross Motor | Ambulant; limited left hip flexion (squatting difficult due to Perthes disease) |
| Fine Motor | Able to write, draw; average student |
| Speech / Language | Fluent, communicates well |
| Social / Behavioural | Active in co-curricular activities at school |
Interpretation: Developmentally age-appropriate. Functional limitation of left hip secondary to Perthes disease — not a developmental delay.
Education: Attending SK Bakar Arang. Average student, active in curricular activities.
FAMILY HISTORY
| Member | Age | Occupation | Medical History |
|---|
| Father | 35 y/o | Technician | NKMI; active smoker |
| Mother | 34 y/o | Housewife | Asthma on MDI |
| 2nd child (sibling) | — | — | Son, NKMI |
No family history of autoimmune disease, HSP, or renal disease specifically documented — to clarify. No consanguinity mentioned.
SOCIAL AND ENVIRONMENTAL HISTORY
- 1st child out of 2 siblings
- Lives with parents and younger brother
- Father is an active smoker — passive smoke exposure at home (relevant given mother has asthma and child is on inhalers)
- Mother has asthma on MDI — atopic family background
- Attends SK Bakar Arang — average student, socially active
- No recent travel, no sick contact
- No pets mentioned
Effect of illness on family:
Recurrent admissions and planned surgery (Perthes — 20/7/2026) place significant physical and emotional burden on family. Mother is primary caregiver. Father works as technician. School attendance likely affected by admissions and hip pain.
SUMMARY OF HISTORY WITH PROVISIONAL DIAGNOSIS
Muhammad Mikhal is an 8-year 5-month-old Malay boy with known HSP (4th admission, discharged 8/6/2026), Perthes disease of left hip (planned operative 20/7/2026), and familial short stature, presenting with 1 week of worsening non-blanching palpable purpuric rash over bilateral limbs, trunk and abdomen, 1 week of frothy urine (resolving), abdominal pain since 1am today (periumbilical, cramping, partially relieved by ibuprofen), and right upper limb swelling noted at ED. UFEME shows blood 2+ with negative protein — raising concern for early HSP Nephritis.
Provisional Diagnosis: Recurrent Henoch-Schonlein Purpura, rule out HSP Nephritis

CLINICAL SUMMARY / ANALYSIS
A. PROVISIONAL DIAGNOSIS: Recurrent Henoch-Schonlein Purpura (HSP), Rule Out HSP Nephritis
Points IN FAVOUR:
- Prior confirmed HSP (4th admission, discharged 8/6/2026)
- Classic tetrad: palpable purpura + abdominal pain + joint involvement (history of hip pain) + renal involvement (frothy urine, haematuria 2+ on UFEME)
- Non-blanching palpable purpuric rash over dependent areas and trunk
- Periumbilical cramping abdominal pain
- UFEME: blood 2+ — haematuria, raising concern for HSP nephritis
- Frothy urine (proteinuria possible — though UFEME protein negative; frothy urine may precede detectable dipstick proteinuria)
- Age and sex consistent (peak 4-7 years; males more commonly affected)
- Recent prior HSP episode — recurrence rate ~30%
Points AGAINST:
- UFEME protein negative (frothy urine not yet confirmed as proteinuria on dipstick — though clinical frothy urine observed by family)
- Platelet count 381 — normal (excludes thrombocytopaenic purpura)
- Afebrile — less consistent with infective trigger
- Right hand swelling unexplained by HSP alone (consider localised oedema vs. trauma vs. IV-related)
B. DIFFERENTIAL DIAGNOSES
I. IgA Vasculitis (HSP) with Nephritis
- For: Purpuric rash, abdominal pain, haematuria, prior HSP. Renal involvement (HSP nephritis) occurs in 20-50% of HSP cases.
- Against: Protein negative on UFEME currently; no nephrotic syndrome features yet.
II. IgA Nephropathy (Berger's Disease)
- For: Haematuria, periumbilical pain, similar age group
- Against: No rash; occurs without systemic vasculitis features; less likely given clear HSP diagnosis
III. Systemic Lupus Erythematosus (SLE)
- For: Multisystem involvement, purpuric rash, renal involvement, ANA in process, C3/C4 obtained previously
- Against: ANA previously negative; rash non-malar in distribution; C3 1.48 and C4 0.56 (both elevated — not consumed as in SLE); male sex (SLE rare in males); age
IV. Immune Thrombocytopaenic Purpura (ITP)
- For: Non-blanching purpuric rash
- Against: Platelet 381 (normal); ITP rash typically non-palpable; no systemic features
V. Meningococcaemia
- For: Non-blanching purpura
- Against: Afebrile, haemodynamically stable, well-appearing, no meningism, no toxic features; rash palpable and over limbs/trunk typical of HSP
INVESTIGATIONS

|---|
| Total Protein | 82 g/L | 60 - 80 | Mildly elevated — to monitor |
| Albumin | 34 g/L | 35 - 50 | Mildly low — early hypoalbuminaemia; watch for nephrotic syndrome development |
| Total Bilirubin | 8 µmol/L | < 21 | Normal |
| ALP | 155 U/L | 100 - 350 (paediatric) | Normal for age |
| AST | 17 U/L | < 40 | Normal |
Complement (from 4th admission): C3 1.48, C4 0.56 — both within/above normal (not consumed; argues against SLE/MPGN).
Specific Investigations
UFEME:
| Parameter | Result | Interpretation |
|---|
| pH | 5 | Normal |
| Blood | 2+ | Haematuria — renal involvement in HSP; monitor for progression |
| Protein | Negative | No proteinuria currently — however frothy urine reported clinically |
Urine C&S: Pending — sent to exclude UTI as cause of haematuria.
CXR: Clear — no cardiomegaly, no pulmonary oedema, no consolidation.
AXR: No dilated bowel, no obstruction.
Bedside Abdominal Ultrasound (ED): No free fluid — no significant haemoperitoneum or bowel intussusception.
Pending investigations (ordered):
- ANA (trace result from 4th admission — in process)
- Repeat UFEME and Urine C&S
- FBC, renal profile, LFT, coagulation, blood C&S, CRP at review
FINAL DIAGNOSIS
Recurrent Henoch-Schonlein Purpura (IgA Vasculitis) with Haematuria (Rule Out HSP Nephritis)
MANAGEMENT PLAN
- Observe under room air — keep SpO₂ > 95%
- Nephrotic chart — strict input/output, daily urine dipstick for protein and blood
- Watchout for: bleeding tendencies, worsening rash, abdominal pain escalation, haemodynamic compromise, worsening haematuria or onset of proteinuria
- Continue existing medications:
- MDI Salbutamol 200 mcg PRN
- MDI Budesonide 200 mcg BD
- Avoid NSAIDs (ibuprofen given at home) — ibuprofen use in HSP nephritis may worsen renal function; switch analgesia to paracetamol
- Syr Paracetamol PRN for pain and fever
- Encourage oral intake
- Monitor rash distribution and character — document extent and evolution daily
- Repeat UFEME daily — watch for proteinuria development
- Trace pending ANA result
- Renal team review if proteinuria develops or haematuria worsens
- Appointments to maintain:
- TCA Paeds Ortho HKB for operative procedure — 20/7/2026
- TCA Paeds Surgical HSAH for phimosis — 18/10/2026
- TCA Paeds Clinic — 7/7/2026

- Haemodynamically stable
- Parents educated: monitor urine daily, avoid NSAIDs, return for any renal warning signs
- Appointments confirmed: Paeds Clinic 7/7/2026, Ortho HKB 20/7/2026, Surgical HSAH 18/10/2026
Discharge Diagnosis: Recurrent Henoch-Schonlein Purpura (IgA Vasculitis) with Haematuria — no nephritis, resolved
Key clinical flags:
- Ibuprofen was given at home — counsel parents firmly to avoid all NSAIDs in future; paracetamol is the safe alternative
- Albumin 34 — mildly low; monitor for nephrotic syndrome development at follow-up
- Planned surgery 20/7/2026 — ensure HSP is in remission before operative intervention; inform orthopaedic team of HSP diagnosis and renal status
- Passive smoking exposure — counsel father to quit smoking; relevant to mother's asthma and child's respiratory health
