Definition of CKD
Structural or functional abnormalities of the
kidneys for >3 months, as manifested by
either:
1. Kidney damage, with or without decreased GFR, as
defined by
• pathologic abnormalities
• markers of kidney damage, including abnormalities in
the composition of the blood or urine or abnormalities in
imaging tests
2. GFR <60 ml/min/1.73 m2, with or without kidney
damage

*Stages 1-4 from NHANES III (1988-1994). Population of 177 million with age 20. Stage 5 from USRDS (1998), includes
approximately 230,000 patients treated by dialysis, and assuming 70,000 additional patients not on dialysis. GFR estimated
from serum creatinine using MDRD Study equation based on age, gender, race and calibration for serum creatinine. For
Stage 1 and 2, kidney damage estimated by spot albumin-to-creatinine ratio 17 mg/g in men or 25 mg/g in women in two
measurements.

Management
1 renal chart.
2 insensible loss + urine output as IVF
3IV ceftriaxone 1g daily for UTI
4 renal replacement therapy
5 plan for hemodialysis

PCKD
Autosomal dominant
 The age of presentation of
renal impairment
 Family hx not present and new
mutation only 7%
Autosomal recessive
 The age of presentation of
renal impairment

Follow up
 patient was showing signs of improvement with the vomiting stopped and
activity increases gradually
 RFT was improving after hydration never the less still high:

Follow up

and to start regular dialysis in the day after.

History and history again
 4 weeks ago my patient has had sore throat with associated fever and vomiting and was admitted
to a nearby health center for 2 days receiving injectable penicillin and was discharged on good
condition.
She also has had a complaint of
joint pain with the same episode
and did receive analgesia.

History history and history again
analgesia.
Diclofenac sodium inj 75 mg TDS for 3 days.
Ibuprofen tabs 600 mg 6 hourly for 5 days

NSAID kidney syndromes:
1 prerenal AKI.
2 AIN (acute interstitial nephritis).
 3 AIN plus minimal change nephropathy ( nephrotic
syndrome).
 4 salt and water retention.
 5 hyperkalemia.
 6 CKD and papillary necrosis ( analgesic nephropathy).

AIN
 Acute interstitial nephritis (AIN) is a renal lesion that causes a
decline in creatinine clearance and is characterized by an
inflammatory infiltrate in the kidney interstitium . It is most
often induced by drug therapy.
 AIN is also caused by autoimmune disorders or other systemic
disease (e.g., systemic lupus erythematosus [SLE], Sjögren's
syndrome, sarcoidosis), a variety of infections remote to the
kidney (e.g., Legionella, leptospirosis, and streptococcal
organisms).

Drugs induced AIN ( 90-95%)
The most common drug causes of AIN now include
●Nonsteroidal anti-inflammatory agents (NSAIDs),(60-90%) including selective
cyclooxygenase (COX)-2 inhibitors
●Penicillin's and cephalosporin's ( 20-30%)
●Rifampicin
●Antimicrobial sulfonamides, including trimethoprim-sulfamethoxazole
●Diuretics, including loop diuretics such as furosemide and bumetanide, and thiazide-type
diuretics
●Ciprofloxacin and, perhaps to a lesser degree, other quinolones
●Cimetidine (only rare cases have been described with other H-2 blockers such as ranitidine)

AIN
Clinical manifestations — With AIN from any cause, patients may present with nonspecific
signs and symptoms of acute renal dysfunction. These may include the acute or subacute
onset of nausea, vomiting, and malaise. However, many patients are asymptomatic .
Patients may be oliguric; in a retrospective study that included 60 cases of AIN (92 percent
of which were drug induced, with the remainder idiopathic), oliguria was present among
51 percent . Gross hematuria occurs in approximately 5 percent of individuals .
Radiographic findings – There are no radiographic findings that are diagnostic for AIN.
Radiographic findings, including marked enlargement of kidneys with multicystic
appearance.

Variable course and prognosis with the majority of patient
tend to recover.
Patients with associated connective tissue diseases have the
worst prognosis
Management is stop the drug and manage as AKI

History is the key and core of clinical practice always ask as always there is a
hidden thing.
RFT should be a routine for any ill patient especially if non specific presentation
is encountered.
AKI and CKD can be very challenging in differentiating them.
NSAID are hazardous drugs and need to be used in the lowest effective dose.
