15. NEPHROTIC GNs
less inflammation (proliferation) than the nephritic GNs
“nephrotic” urine:
see less hematuria, more proteinuria
azotemia less common, or at least less rapid
hypertension not as common
16. NEPHROTIC SYNDROME
Is a syndrome, not a disease
collection of symptoms and signs due to a common pathology
Can be caused by a variety of diseases
Must look for the specific disease
17. DEFINITION
Syndrome consisting of the following:
proteinuria > 3.5 grams/24 hrs
hypoalbuminemia
hyperlipidemia and lipiduria
peripheral edema
19. HYPOALBUMINEMIA
due to losses in urine
liver attempts to compensate by albumin synthesis (up to 50-
60%)
probably in response to plasma oncotic pressure
general correlation between urine losses and serum levels
20. MECHANISM
glomerular abnormality “nephrotic” range
proteinuria is initial insult
generally > 3.5 grams/24 hrs
hypoalbuminemia
hyperlipidemia/lipiduria
21. HYPERLIPIDEMIA
see triglycerides, VLDL, LDL, Lp(a) in serum
see lipid in urine in form of:
free fat droplets
fatty casts
oval fat bodies
22.
23. HYPERLIPIDEMIA
vascular risk likely the same as for non-
nephrotics
nephrotic pts may have 5.5x greater risk for MI
HMG CoA reductase inhibitors (“statins”)
are drugs of choice
24. MECHANISM
glomerular abnormality “nephrotic” range
proteinuria is initial insult
generally > 3.5 grams/24 hrs
hyperlipidemia/lipiduria
hypoalbuminemia
peripheral edema
(+ renal salt retention)
25. Glomerulopathy
Primary
Secondary
some glomerulopathy
can present as more than one syndrome at different times
26. The Spectrum of Glomerular

30. OTHER COMPLICATIONS
progression to ESRF
EDEMA
infection
hypercoagulation
risk of complication correlates with degree of proteinuria
reduction of proteinuria leads to reduction in risk
if proteinuria cannot be reduced, then risk must be addressed
hyperlipidemia
34. PATHOGENESIS
MCD and FSGS
T cells produce abnormal cytokine that leads to
glomerular epithelial cell damage
retraction of podocytes due to ?interaction with anchoring
proteins
b-dystroglycan
a3-b1 integrin
Membranous
due to immune complex deposition
35. PATHOGENESIS
Causes
most commonly idiopathic (“primary”)
90% of cases
may be secondary to:
drugs..(NSAIDs, lithium, gold)
malignancy
infections..(HIV, hepatitis B+C)
36. PRESENTATION
Symptoms
usually present with
edema
facial, lower limb,
arms/hands
often quite abrupt
with MCD
otherwise well. .don’t look
sick
may complain of foamy
Signs
pitting edema in
dependent areas
usually not much else
37. INVESTIGATIONS
Urine
dipstick strongly (+) for protein, little
blood
usually more than 3.0g/24 hr on
collection
microscopy shows lipiduria
free fat droplets
oval fat bodies
fatty casts
Blood
hypoalbuminemia
hyperlipidemia
creatinine usually normal or mildly
elevated
40. PROGNOSIS
MCD MGN FSGS
Persistent
proteinuria
60-70% remit or
stabilize
persistent
proteinuria
Renal failure
usually NOT a
concern
30% chance of
progression to ESRF
over 15 yrs
5 yr renal
survival 60-90%
10 yr renal
survival 30-50%
41. TREATMENT
MCD
corticosteroids the drug of choice
in children, biopsy usually not done straight to steroids with nephrotic
syndrome
in adults, biopsy usually done for diagnosis first
1 mg/kg daily usual dose
may require 4-8 wks. before response is seen
42. TREATMENT
MGN
all pts should receive angiotensin converting
enzyme inhibitors (ACEi) or angiotensin receptor
blocking agents (ARBs)
2nd line treatment reserved for those pts at risk of
progression
elevated creatinine at presentation
normal GFR after 3 yrs is good sign
proteinuria > 10g/24 hrs
esp if > 6 months duration
43. TREATMENT
FSGS
corticosteroids the drug of choice
2 mg/kg alternate days is usual dose
may require 3 months before response is seen (often 6-9 months for full
response)
50% remission rate
44. TREATMENT
3 main 2nd line agents include
corticosteroids
variable results when used alone
best used in combination with another agent
cyclophosphamide
probably more effective than steroids alone but
higher toxicity
cyclosporine
may also be useful as first line…usually less toxicity
45. MGN and FSGS
Recommendations
asymptomatic, protein < 3.5 g/day ACEi/ARB
asymptomatic, protein > 3.5 g/day and no risk factors
ACEi/ARB
symptomatic, protein > 3.5 g/day ACEi/ARB + 2nd line
agent
asymptomatic, protein > 3.5 g/day + risk factors
ACEi/ARB + 2nd line agent
47. TAKE HOME MESSAGE
some glomerular diseases present with a
“nephrotic” picture
proteinuria, edema, hyperlipidemia,
hypoalbuminemia
thrombosis, infection
these diseases may progress to ESRF but
usually very slowly
renal Bx is usually the only way to make a
firm diagnosis

Disease Burden
1. 5% of the general population are Sub-clinically Hypothyroid
2. 15 % of all women > 65 yrs. are hypothyroid
3. Detecting sub-clinical hypothyroidism in pregnancy is highly essential
– order for TSH and FT4 routinely in all pregnant women at the
beginning of each trimester
4. All persons aged above 60 years – Order for TSH

• Treatment of choice is levothyroxin
• Branded thyroxine recommended
• No divided doses - illogical

Goal : normalize TSH level – 25, 50 and 100 mcg tablets avail.
Starting dose for healthy patients < 50 years at 1.0 µg/kg/day
Starting dose for healthy patients > 50 years should be < 50 µg/day. Dose ↑
by 25 µg, if needed, at 6 to 8 weeks intervals.
Starting dose for patients with heart disease should be 12.5 to 25 µg/day and
increase by 12.5 to 25 µg/day, if needed, at 6 to 8 weeks intervals
Start Low and Go Slow

How the patient improves
Feels better in 2 – 3 weeks
Reduction in weight is the first improvement
???????????????????
Facial puffiness then starts coming down
Skin changes, hair changes take long time to regress
TSH starts showing decrements from the high values
TSH returns to normal eventually

• Case Report
• A 60years old male patient presented with symptoms of
insidious onset, painless, progressive abdominal
distension since 2 months and progressive swelling of
both lower limbs since 1 month.
• He also had constipation and progressive hoarseness
of voice for 2 months.
• He had no history of chest pain, shortness of breath,
orthopnea, paroxysmal nocturnal dyspnea, jaundice,
abdominal pain, hematemesis, melena, urinary symptoms,
anorexia or weight loss.
• He was a chronic smoker for last 25 years and non-
alcoholic.
78. www.drsarma.in
78
• Examination revealed mild periorbital and facial puffiness along
with bilateral pitting pedal edema.
• His skin was dry and coarse.
• Neurological examination revealed delayed relaxation of ankle
jerks.
• The patient was afebrile with a pulse rate of 75/min, blood pressure
130/80 mm of Hg and elevated jugular venous pressure.
• On cardiopulmonary examination there was muffled heart sounds
with absent breath sounds.
• Chest radiograph showed massive cardiomegaly with bilateral
pleural effusion.
• Ultrasonography abdomen showed moderate ascites and computed
tomography chest and abdomen revealed massive pericardial
effusion, bilateral pleural effusion and moderate ascites.
79. www.drsarma.in
79
• Electrocardiogram showed low voltage QRS complexes .
• 2D Echocardiogram done subsequently showed a large
circumferential echo free space consistent with massive pericardial
effusion and evidence of cardiac tamponade (diastolic collapse of
right atrium and right ventricle free wall) with preserved left
ventricular systolic function, ejection fraction 55%.
• Viral serology for both hepatitis B and C were negative,
• UGI endoscopy and colour doppler of abdomen were done to
rule out portal hypertension and both were normal.
80. www.drsarma.in

Ascitic fluid study showed total cells of 100/ cumm with 98%
lymphocytes, high protein (3.24 gm%) and high serum ascitic
albumin gradient (SAAG - 1.91) and normal adenosine
deaminase level (ADA - 6.8 U/L) .
Pleural fluid examination showed total cells of 200 / cumm
with 90% lymphocytes, high protein (3 . 97 gm%), normal
sugar and normal ADA level (8.1 U/L).
Cytology of both the fluids were negative for malignancy.
In view of cardiac tamponade, pericardiocentesis was done with
aspiration of about 1500 ml straw colour fluid.
Analysis of fluid showed total cells of 10 /cumm with high protein
(5.3 gm%), normal ADA level (8.3 U/L), and cytology revealed
mainly lymphoid and degenerated cells but no malignant
cells.
Culture of the pericardial fluid was negative for bacteria and acid
81. www.drsarma.in

Thyroid function tests showed TSH 137.8 mIU/ml (normal
range 0.4 – 4), free T4 0.45 ng/dl (normal range 0.89
– 1.76), and free T3 0.63 pg/ml (normal range 0.92 – 2.78).
Ultrasonography revealed atrophic changes in both thyroid
lobes. TPO antibody was negative.
Subsequent hospital course was uncomplicated and he was
discharged with gradually escalating dose of levothyroxine
from 50 to 100 microgram daily.
On 4 weeks follow up he was in good health and had
abatement of ascites, pleural effusion and tissue edema
and only minimal pericardial effusion left.
His TSH was 30.1m IU/ ml and he continued on a
maintenance dose of 100 microgram with regular follow up.
82. www.drsarma.in
82
The recent studies, however, conclude that PE is extremely
infrequent in hypothyroidism, with an incidence of 3% to 6%.
The mainstay of treatment for thyroid PE is simple thyroxine
replacement, except in those patients w i t h pericardial
tamponade or impending tamponade, this condition mandates
urgent pericardiocentesis.
Pleural effusion per se due to hypothyroidism is rare and
requires careful exclusion of other associated conditions.
Effusions solely due to hypothyroidism have borderline
characteristics between exudates and transudates and show
little evidence of inflammation.
83. www.drsarma.in
83
In conclusion hypothyroidism can have rare modes of
presentations
.
It can present with either isolated effusion or in
combination of multiple body cavity effusions along with
tissue edema.
High index of clinical suspicion is required to diagnose
such cases.
The treatment is simple and gratifying with almost
complete regression of findings after thyroid hormone

Editor's Notes
Spectrum of glomerular diseases. At one extreme, specific injury to podocytes or structural alteration of the glomerulus affectingpodocyte function (for example, by scarring or deposition of excess matrix or other material) causes proteinuria and nephrotic syndrome (see Box 17.11 ,p. 475). The histology to the left shows diabetic nephropathy. At the other end of the spectrum, inflmmation leads to cell damage and proliferation,breaks form in the GBM and blood leaks into urine. In its extreme form, with acute sodium retention and hypertension, such disease is labelled nephriticsyndrome. The histology to the right shows a glomerulus with many extra nuclei from proliferating intrinsic cells, and inflx of inflmmatory cells showscrescent formation (arrows) in response to severe post-infectious glomerulonephritis. (FSGS = focal and segmental glomerulosclerosis; MCGN =mesangiocapillary glomerulonephritis)
