Recall 1 :
1- A 14-year-old boy presents with flank pain, hematuria, and proteinuria. He recently had a flu-like illness, and a similar episode occurred two days ago. What is the most likely diagnosis?
A) Post-streptococcal glomerulonephritis
B) IgA nephropathy
C) Henoch-Schönlein purpura (HSP)
D) Lupus nephritis

Recall 2:
An 18-year-old man is evaluated because of acute kidney injury 3 days after an upper respiratory tract infection. Examination reveals lower limb pitting edema up to the knee levels. His laboratory investigations were normal 3 days ago but are repeated today (see lab results). Which of the following is the most likely diagnosis?
A. IgA nephropathy
B. Lupus nephritis
C. Acute interstitial nephritis
D. Post-infectious glomerulonephritis
Right is : A. IgA nephropathy

Recall 3 :
Q-20-year-old man with hematuria occurring 1-dayfollowing a throat infection. Which of the following is the most likely diagnosis?
A – IgA nephropathy
B-Membranous nephropathy
C-Post-infectious glomerular nephritis
D-Focal segmental glomerulosclerosis
Right is: A – IgA nephropathy
الكلمة السرية للتشخيص: IgA nephropathy
يقولك في سيناريو أمريض من يوم إلى ثلاثة أيام كان عنده upper respiratory tract infection، ثم حصل له hematuria — بالضبط نفس مرض post-infectious glomerulonephritis، لكن الفرق هنا في الوقت.
لذلك، مرض IgA nephropathy يقولك:
من يوم إلى ثلاثة أيام كان عنده upper respiratory tract infection، ثم بعد يوم حصل له hematuria.
واحفظوها بهذه الطريقة:
كلمة (IgA) فيها ثلاث حروف = يعني من يوم إلى ثلاثة أيام.
بينما مرض post-infectious glomerulonephritis، لأن مصطلحه طويل، فالسؤال يقولك:
منذ أسبوعين إلى ثلاثة أسابيع كان عنده infection.
اربطوها بالطريقة هذه عشان ما تنسوها أبداً.

A. Steroids
B. Diuretics
C. ACE inhibitors
D. Antibiotics
Correct answer: A. Steroids
Note :
Observation is the most appropriate management • steroids / immunosuppressants not be shown to be useful. Treatment with corticosteroids is usually reserved for those patients with hypertension and a rising creatinine.
• When there is nephrotic range proteinuria (>3 g/day) an 8-12 week course of prednisolone should be prescribed.
• If the proteinuria is <3 g/day an ACE inhibitor can be used.
