Title of the study :“A STUDY ABOUT THE CHANGES IN LEVELS OF

PANCREATIC ENZYMES IN CASES OF CHRONIC

RENAL FAILURE”

Introduction

Chronic renal failure (CRF) encompasses a spectrum of different pathophysiologic process

associated with abnormal kidney function and a progressive decline in glomerular filtration rate

[1].CRF is caused due to many diseases out of which the most common is glomerulo nephritis.

Increase in blood levels of NPN(Urea creatinine and uric acid) is referred to as azotemia [2],

which is the hallmark of kidney failure.

Uraemic syndrome is the terminal manifestation of renal failure, which is characterised by

azotemia, electrolytes imbalance, anaemia, atherosclerosis, hypertension, decreased immunity due to

impaired WBC function which causes susceptibility to many infections, altered calcium metabolism

causing renal osteodystrophy, gastro intestinal(GI) symptoms like loss of appetite, nausea, vomiting

and rarely GI bleeding and very rarely acute pancreatitis.

Diagonising these complications may prevent further worstening of the condition of CRF

patients. Since CRF patients suffer from pain abdomen and vomiting already, it is difficult to

differentiate these symptoms from that of acute pancreatisis. Quantitative estimation of serum

amylase and serum lipase will show a marked increase in level when we compare the levels of these

enzymes in CRF patients without acute pancreatitis.

The present study focuses on the level of pancreatic enzymes in CRF patients without known

pancreatitis and to find out the incidence of acute pancreatitis in these patients.

Aims and Objectives:

The main aim of the study is to investigate about the changes in levels of pancreatic enzymes in

cases of chronic renal failure.The objectives of the study includes the following

a) To detect the incidence prevelance of acute pancreatitis in known CRF patients with or without

dialysis.

b) To find out the diagnostic value of serum amylase by measuring the rate of serum amylase

clearance to the rate of creatinine clearance in relation to the stages of chronic renal failure

(i.e.) mild moderate and severe

c) To evaluate if serum creatinine, serum amylase and serum lipase have any correlation with

the severity of CRF (i.e.) mild moderate and severe

REVIEW OF LITERATURE

A study by Royse VL,Jensen DM, Corwin HL in1987 suggested by serum amylase activity

greater than threefold elevation suggest coexistence of pancreatitis in CRF patients[3].

Another study by Lin XZ,Chen TW, in the year 1988 concluded that elevation of pancreatic

enzymes in CRF patients is more frequent and more extensive and the extent of increase is related to

renal function and not to the dialysis status[4].

Collen MJ and Ansher AF in the year 1990 suggested that elevation of serum amylase is not

evident until creatinine clearance falls below 50 ml/min[5].

1n1976 E.B.Pederson and A.Brock as a result of their work suggested that the ratio of C am/Ccr

was significantly increased in patients with severe renal impairment when compared to patients

treated with renal allotransplantation. The elevation of serum amylase activity in patients with CRF is

primarily due to decreased glomerular filtration rate. So the value of Cam/Ccr for for diagonising acute

pancreatitis is doubtful in patients with severe renal disease[6].

Micheal D and Levitt M.D, in 1969 suggested that in renal insufficiency Cam was in

proportion with Ccr. The clearance of amylase makes urinary amylase and more more sensitive

indicator of pancreatitis than in the serum. The diagonistic value of amylase is enhanced if amylase

excretion is related to creatinine cxcreation[7].

Giuseppe Montalto, Antonio Carroccio, suggested that increase in pancreatic enzymes during

chronic renal pathology is slight but frequent[8].

Pitchumoni, C.S, Arguello.P concluded that acute pancreatitis in CRF is frequently of

unknown cause suggesting the role of either CRF or other factors irrespective of cause acute

pancreatitis in CRF is a serious disease associated with a high morbidity and mortality[9]

WORK ALREADY DONE: No

MATERIALS AND METHODS:

a) Whether the study involves animals humans or both: Humans

b) Type of study: Cross sectional study.

INCLUSION CRITERIA :

c) 50 patients with CRF.from Nephrology Department of Sree Mookambika Institute of

Medical Sciences between the age group from 30 to 80 years

EXCLUSION CRITERIA:-

1) Chronic alcoholics with portal hypertension

2) Known cases of previous pancreatitis

Parameters to be studied: Blood Urea, Serum creatinine, Serum Amylase, Urinary Amylase, Serum

Lipase, Serum Calcium and Serum Phosphorous.

Procedure: The protocol is to be submitted to the human ethical committee for its approval. After

getting approval from the HEC written onformed consent is to be obtained fronm all the volunteers

before enrolling them in to study. The study is to be conducted in collaboration with the nephrology

department of SMIMS.50 volunteers are to be recruited from nephrologic clinic of medicine

department of SMIMS after considering the inclusion and exclusion criteria. 50 patients with CRF

and other matching parameters are to be recruited in to the study.

Before the study the volunteers are to informed about the procedure of the study.

Detailed history of whether the patient is under dialysis will be recorded on a case record form.A sample of 2 hours timed urine is to be collected during whichperiod about 10 cc of blood is to be collected in a dry syringe.Whole blood will be used for blood urea estimation.Amylase,lipase,calcium and phosphorus will be estimated using the serum.

Determination of serum lipase will be done byCNPG3 (ChloroNitroPhenol) method using alpha amylase kit.Determination of serum creatinine is done by Modified Jaffes method using Biosystem kit.Determination of blood urea is done by Urease-GLDH(Glutamate Dehydrogenase )method,using Biosystem kit.Determination of serum calcium is done by modified OCPC(OrthoCresolPhtaleinComplex) method using Biosystem kit.Determination of serum Phosphorus is done by UV End point method using Bayers kit.

Methods of Analysis: Data is to entered in excel spread sheet and is to be analysed using statistical

software Epi Info Version 3.5.3. Analysis is to be done by simple proportion, mean ± SD and

Chisquare test.

Hypothesis

There is appositive correlation and association between serum amllase and serum lipase and the

severity of CRF

OBJECTIVES :-

Chronic renal failure (CRF) is a condition associated with abnormal kidney

function and a progressive decline in glomerular filtration rate. Increase in blood

levels of urea, creatinine and uric acid is the hallmark of kidney failure. Diagnosing

the complications may prevent further worsening of the condition in CRF patients

Since CRF patients suffer from pain abdomen and vomiting already it is

difficult to differentiate these symptoms from that of acute pancreatitis. Estimation of

serum amylase and serum lipase will show a marked increase in level of these

enzymes in CRF patients without known acute pancreatitis. The present study is

done to study the level of pancreatic enzymes in CRF patients without known

pancreatitis & to find out the incidence of acute pancreatitis in these patients.

PROCEDURE :-

50 volunteers with CRF will be recruited from the nephrology department of

SMIMS, who are of the age group between 30 to 80 years for the study.

The study will be done by drawing 10ml of blood from the volunteers & will be

tested for serum amylase & Serum lipase. Prior to the test the procedure will be

explained thoroughly to you. Value of all pancreatic enzymes level obtained from you

will be saved in the computer. Hard copy of all the parameters will be maintained in a

separate file and the values will be taken for analysis.
