Question: What is diagnosis?
What is the cause of metabolic abnormality and how will u manage the patient?



Answere:  Diagnosis is Rhabdomyolysis. There are two important clues. One is that patient had a fall. Second there is renal failure with disproportionally raised creatine. There is muscle injury ( myositis). Myoglobin is released which is toxic to renal tubules and precipitate renal failure. calcium is found decrease and it binds with myoglobin and potassium and phosphate are high and there are liberated heavilly from damaged muscles.
The management involves adequate hydaration and alkalinization of the urine to reduce precipitation of myoglobin in the renal tubules. Avoid loop diuretic as they cause acidic urine.

Spina Bifida(Neurogenic bladder.)

 Neurogenic bladder , which is usually treated by ileal conduit. It is urinary diversion procedure in which terminal part of intestine , Ileum is dissected and anastomosed with ureters with one end and second end with skin (Stoma formation). we often come across cases in nephrology practice where patients with history of Spina bifida come as renal failure which is complication of this neurogenic bladder.
Now these patients usually need renal replacement therapy. Whenever we consider Peritoneal dialysis in these patients, we must consider patients ventriculo-peritoneal shunt which is often placed in these pateint because of Hydrocephalous. Therefor these children would be prone to meningitis if PD is initiated.

Interstitial nephritis

How interstitial nephritis is presented and what are the some of the drugs which cause?

It is usually presented with fever. maculopapular rash, eosinophilia, eosinophilurea.

Penicillin analogue, cephalosporin, sulphonamide, NSAIDs, cimitidine, allopurinol etc.

Question solution

1. A 30 year female of Chronic nephritis/CRF had a live related renal transplant 1 year back. She seeks your advice regarding future pregnancy. She is receiving Prednisolone, Cellcept and cyclosporine as maintenance immunosuppression . Her BP is well controlled with Enalpril 5mg once daily.

a)      How would u assess her suitability of successful outline of pregnancy what advice would you give?

b)      What if any modification in her current medication is required should she become pregnant?

c)       What complications are expected?

Answere:   Assessment of suitability regarding pregnancy and advice entails:

Assessment of her current renal function, her urine detail report and her course post transplant sofar.

At least 1 year post‐transplantation

 Stable renal function with creatinine <2 mg/dl

No recent episodes of acute rejection

 BP ≤140/90 mmHg on medications

 Proteinuria <500 mg/day

Prednisone ≤15 mg/day Azathioprine ≤2 mg/kg/day

Cyclosporin ≤4 mg/kg/day

 Normal allograft ultrasound

b) Replace cellcept with azathioprin and enalpril with methyldopa. Atenolol and metoprolol can also be given. In severe hypertension nefidipine and hydralazine can be given.

d)     Gestational diabetes, preeclamsia, preterm labour .

 Rate of uti more especially whose primarily renal disease is secondary to Pyelonephritis.

Nephrotic syndrom

What are the diagnostic criteria for nephrotic syndrome?
Nephrotic syndrome is a syndrome that results from severe proteinuria. Heavy glomerular
protein losses (3.5 g in an adult or .40 mg/m2/hour in a child) lead to the other three
criteria for nephrotic syndrome: hypoalbuminemia, hyperlipidemia, and usually edema.
From a practical standpoint, measuring a urine total protein/creatinine ratio is preferable
to collecting a 24-hour urine for protein. A ratio of 3.5 correlates with nephrotic-range
proteinuria.
2. What is minimal change disease (minimal change nephrotic syndrome)?
Minimal change disease (MCD) is a disorder of glomeruli that leads to heavy proteinuria.
Renal biopsy shows normal glomeruli by light microscopy but will show effacement of the
podocyte foot processes by electron microscopy. Immunofluorescent microscopy typically
is negative, although some patients may show staining for immunoglobulin M (IgM) in the
mesangial regions of the glomeruli. Technically, a patient cannot be said to have MCD with
certainty without having had a kidney biopsy. However, so many young children with
nephrotic syndrome have MCD that kidney biopsies are only performed in those children
with atypical findings or in those who are resistant to immunosuppressive therapy. Older
adolescents and adults are diagnosed with MCD after a kidney biopsy is performed.
3. How likely is MCD to be the cause of nephrotic syndrome in any individual?
MCD is the cause of nephrotic syndrome in about 90% of children younger than age 6, in
about 65% of older children, and in about 20% to 30% of adolescents. In adults only about
10% to 25% of nephrotic syndrome results from MCD, but it represents the third most
common cause of nephrotic syndrome in adults after membranous nephropathy and focal,
segmental glomerulosclerosis.
4. What causes MCD?
MCD is an immune-mediated disease, felt to be mediated by a circulating factor capable of
inducing proteinuria. Presumably the circulating factor is secreted by lymphoid cells, and it
functions as a vascular permeability factor that directly affects the function of the podocytes.
Although the majority of cases of MCD are idiopathic, MCD, particularly in adults, may be
associated with neoplastic disease such as lymphoma, toxic or allergic reactions to drugs,
certain infections, allergies, or other autoimmune disorders.
5. How common is MCD?
The prevalence of MCD in children is about 16 per 100,000 children, but it is much less
prevalent in adults.
6. What is the typical clinical presentation of MCD?
Patients with MCD typically present with mild to severe edema. Because the onset with
periorbital edema commonly follows an upper respiratory infection in young children,
nephrotic syndrome may sometimes be confused with an allergic reaction until a more
thorough evaluation is performed. I
