Henoch-Schonlein Purpura: Follow-up
Updated: Sep 28, 2009
Follow-up
Further Inpatient Care
- Management of Henoch-Schoenlein purpura (HSP) includes adequate hydration; immediate discontinuation of any exposure to antigenic stimulants (ie, drugs); and follow-up each week for the first month, every other week for the second month, and monthly thereafter until abnormal urinary findings subside.
Further Outpatient Care
- Monitor kidney function in patients who initially had kidney involvement.
Inpatient & Outpatient Medications
- Once the initial course of prednisone is administered, additional prednisone appears to have no role.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) can be administered for joint problems. Because of Reye syndrome, the use of NSAIDs should be discussed with the patient's physician.
Complications
- Myocardial infarction
- Pulmonary hemorrhage
- Pleural effusion
- Intussusception
- GI bleeding
- Bowel infarction
- Renal failure
- Hematuria
- Proteinuria
- Seizures
- Mononeuropathies
- Recurrence of symptoms, specifically those of renal impairment (rare)
Prognosis
- The prognosis is excellent; however, complications arise in rare cases.
- The disease usually spontaneously resolves.
- Children younger than 3 years have a shorter, milder course than that of other patients and fewer recurrences than other patients.
- A clinical course with complete resolution of the disease usually occurs in patients with the following:
- Mild kidney involvement
- No neurologic complications
- Disease that lasts less than 4-6 weeks initially
- Recurrences occur in 50% of patients within 6 weeks but can happen as late as 7 years after the initial disease. The higher the number of recurrences, the higher the likelihood of permanent renal damage.
- Persistent renal disease develops in 2-5% of patients (<1% develop ESRF). Age older than 6 years is a negative prognostic indicator.
- Predictors of serious nephropathy or ESRF include the following:
- Bloody stools
- Rash persistence
- Signs of nephritis or nephrotic syndrome (progresses to ESRF within 10 years in 50% of patients)
- Renal biopsy with extensive glomerular crescents
Patient Education
- Inform patients that the disease is most likely to resolve with few residual adverse effects but that relapses are possible. Explain that severe kidney involvement is rare, but if it does occur, they may require aggressive treatment.
- For excellent patient education resources, visit eMedicine's Kidneys and Urinary System Center. Also, see eMedicine's patient education article Blood in the Urine.
Miscellaneous
Medicolegal Pitfalls
- Failure to diagnosis Henoch-Schoenlein purpura (HSP) and monitor patients appropriately
- Failure to adequately monitor patients with Henoch-Schoenlein purpura and renal involvement for signs of renal dysfunction and failure
- Failure to deal with rare complications involving the kidneys, intestines, CNS, or joints
Special Concerns
- All pregnant women with even mild renal symptoms at Henoch-Schoenlein purpura onset should be carefully observed during and after pregnancy.
- In adults with Henoch-Schoenlein purpura, permanent renal involvement is not uncommon.
- Hematuria at disease onset and persistence of renal manifestations during the occurrence of Henoch-Schoenlein purpura can be significant predictors of possible development of renal sequelae.
- These manifestations plus other features, such as onset in summer, anemia at disease onset, or relapses of the disease, may predict the development of renal sequelae in most patients.
- Henoch-Schoenlein purpura may mimic an abdominal emergency and, in its severest form, result in small-bowel infarction and/or perforation.
- When terminal renal failure develops, long-term hemodialysis should be instituted until a kidney is available for transplantation. Mesangial deposits of IgA are common in the graft, but they rarely lead to clinical manifestations of recurrent glomerulonephritis.
- Medications can cause Henoch-Schoenlein purpura. Losartan therapy has been reported to induce Henoch-Schoenlein purpura.
- Children who have demonstrated renal manifestations in the acute phase and continue to have hematuria or proteinuria should be examined every 3-6 months because renal failure or hypertension can develop up to 10 years after disease onset.
- When patients present with nephrotic syndrome, hypertension, and rapidly deteriorating renal function, biopsy frequently shows circumferential crescents in most of the glomeruli. Approximately 60% of patients develop renal failure, either in the acute phase of the disease or after an interval of several years.
