Kathmandu, Nepal — February 11, 2026
A recent case report published in the Annals of Medicine & Surgery has shed light on the diagnostic challenges of Immunoglobulin A vasculitis (IgAV) in adults, documenting the first known case in Nepal where the disease masqueraded as recurrent gastroenteritis for an entire year.
Historically known as Henoch-Schönlein purpura, IgAV is a small-vessel vasculitis common in children but rare—and often more severe—in adults. This specific case involved a 57-year-old male who suffered through five episodes of abdominal pain, vomiting, and loose stools over 12 months before the tell-tale sign of the disease—a purple, patchy rash—finally appeared.[If possible, please give a short introduction of IgA in a line, maybe to let the readers know what it is and why it is important to know]
A “Diagnostic Blind Spot”
The patient’s journey highlights what researchers call a “diagnostic blind spot”. Because his initial symptoms were strictly gastrointestinal, his condition was repeatedly misidentified as acute gastroenteritis and treated temporarily with antibiotics.
It wasn’t until the patient developed palpable purpura (raised reddish spots) on his limbs and trunk, along with mild knee pain and signs of kidney involvement, that clinicians at the Nepal Medical College and Teaching Hospital were able to reach a diagnosis.
Challenges in the Nepali Context
The report underscores the practical hurdles of diagnosing rare autoimmune conditions in resource-constrained settings:
- Reliance on Clinical Criteria: While biopsy with immunofluorescence is considered the gold standard for diagnosis, it is often unavailable or financially inaccessible for many patients in Nepal.
- Clinical Vigilance: In this case, doctors relied on the EULAR/PRINTO/PRES criteria, which include the presence of purpura plus at least one other symptom like abdominal pain or renal involvement.
Rapid Recovery and Lessons Learned
Despite the year-long delay, the patient’s recovery was swift once the correct treatment began. He was prescribed 60 mg of oral prednisolone daily.
- 1 Week:Marked clinical improvement with complete recovery of the rash and abdominal pain.+1
- 6 Months: The patient remained asymptomatic with no recurrence of symptoms after a two-month steroid taper.
Medical experts involved in the study emphasize that IgAV should be considered in adults presenting with unexplained, recurrent abdominal pain, even in the absence of an initial rash. Early recognition and timely initiation of corticosteroid therapy can significantly improve patient outcomes and help prevent long-term complications, including persistent kidney disease.
