1. INTRODUCTIONAcute cholecystitis and cholelithiasis are one of common health problems of Libyans. [1] Acute cholecystitis or bile gallbladder stones are one of the major surgical problems in the Libyan population and account for many hospital admissions and surgical interventions. This study was done to estimate causes and risk factors of AC among general population of Benghazi city in Libya. Reflux of pancreatic secretions into the biliary duct due to a defect in motility of gallbladder or biliary tree or spastic episodes of Sphincter Oddi may cause injury to gallbladder mucosa and biliary tract which may precipitate acute cholecystitis. Pancreatic biliary reflux (PBR) therefore may cause such reflux of pancreatic juice into gallbladder and biliary tract. This problem is probably related to obesity, cardiovascular disorders (CVD), metabolic syndrome, and dietary habits. Studies on gallstone composition carried out a close link with dietary habits and ethnicity. The biliary composition has been demonstrated by many researches for several years. Gallstone formation is relatively increased with consumption of dietary fats, age and gender. [2], [3] Estimation of pancreatic amylase in gallbladder bile as well as in serum of patients with acute cholecystitis (AC) may be considered as a biomarker of PB reflux. Serum and bile pancreatic amylase levels as marker for diagnosis of acute cholecystitis" by investigate biliary composition especial alpha amylase pancreatic, total amylase, liver enzymes estimation the correlation between (AST, ALT, ALP and Bilirubin total, C-RP and lipid profile in gallstone disease patients and estimate the correlation between (Cholesterol, HDL, LDL, VLDL) concentration in serum and biliary gallbladder, presence of gallstones, age, in both gender patient with gallbladder diseases. 2.
MATERIALS
AND METHODS
Twelve hours fasting overnight venous blood samples were collected from (103) acute cholecystitis cases, undergoing elective open or laparoscopic cholecystectomy. Simultaneously, the anesthesiologist obtained a (5) ml sample of venous blood from a peripheral vein blood was collected in ethylene di amine tetra acetic acid (EDTA) and plain tubes. After removing the needle, the blood was allowed to clot for at least (10-15) min at room temperature then serum was separated by centrifugation at 3000 rpm for 15 minutes. In addition, carefully transferred to plastic tubes and stored at 2-8 ºC for 24 hours prior to assay. Serum samples were either analyzed immediately or stored at -20 ºC until they were analyzed for further use. The bile gallbladder samples were collected from patients
(103) had acute cholecystitis, undergoing elective open or laparoscopic
cholecystectomy remove gallbladder during surgery, before initiating the dissection of the Calot’s triangle
5 ml of bile obtained from the gallbladder using a sterile syringe were
stored at 4-8 oC, and analyzed for pancreatic alpha amylase, total
amylase, lipid profile, C- reactive protein and liver enzyme within a week. The biliary and serum
samples were kept at room temperature (21 -25.8°C), delivered for processing and
analysis within 2 hrs. 3. RESULTSFrom the results it is observed
mean values ± SD of the study group included 103 patients with a mean age and ±

In the patients group there was a significant positive correlation between pancreatic alpha amylase and total cholesterol [r ꞊ 0 .746**, p꞊ 0.000]. Serum Triglycerides [r ꞊0 .857**, p꞊ 0.000]. High density lipoprotein- cholesterol (HDL-C), [ r꞊0.772**, p ꞊ 0.000], low density lipoprotein-cholesterol [r ꞊ 0.789**, p꞊ 0.000] and very low density lipoprotein [r꞊0.860**, p꞊ 0.000]. C-reactive protein – CRP (mg/l) showed no significant correlation. Approximately 65 % of patients had high pancreatic alpha amylase levels in bile gallbladder. The mean total cholesterol, TG, HDL-C, LDL-C and VLDL-C levels were significantly higher in the acute cholesystitis (AC) in bile patients compared to the serum them patients. Table 5: Show

that the abnormal biochemical
liver function test of almost all patients resolved rapidly and spontaneously
after cholecystectomy and indicates that there is an acute hepato-cellular
injury in symptomatic gallstones with cholecystitis in the absence of common
bile duct stones and this injury is mild and transient (AST) [r꞊ 0. 923**, p꞊ 0.000], alanine aminotransferase
(ALT) [r꞊ 0 .953**, p꞊ 0.000], alkaline phosphatase (ALP) [r꞊ 0. 900**, p꞊ 0.000], and bilirubin total (TBIL) [r꞊ 0 .932**, p꞊ 0.000]. Patients without significant pancreatic-biliary reflux (PBR) had normal bile levels of pancreatic enzymes (such as amylase). In recent investigation, patients without gallstones showed very low or absence of pancreatic enzymes in their gallbladder bile. Lipid profile did not show significant changes in female patients whereas in male patients levels of cholesterol and triglycerides are increased. Liver function tests showed that AST, ALT and ALP levels are elevated in patients with AC especially in bile of these patients. Therefore, increase in bile levels of amylase along with elevations in liver enzymes may help in early detection of AC. There was significant association between age of the patients and bile amylase levels. Table 7: Show

DISCUSSION
Cholecystitis is inflammation of the gallbladder that develops over hours, usually because a gallstone obstructs the cystic duct, if it develops slowly overtime it is called chronic cholecystitis. Symptoms include right upper quadrant pain and tenderness, sometimes accompanied by fever, chills nausea and vomiting. [3]. In a study done by Geraghty and Goldin in 1994, they stated that there were high proportion (66%) of patients with gallstones and cholecystitis having abnormal liver histology. [4] The most common findings were non-specific reactive hepatitis and large droplet fatty change. Cholecystitis should be regarded as a cause of reactive hepatitis. Some patients with reactive hepatitis had acute inflammatory cells in the portal tracts and that correlated with acute inflammation in the gallbladder Analyses of
frequency showed that acute cholecystitis was more common in females than males
with percent (9% male and 91% female) witch approximately fold higher in
females, this finding similar to previous finding that, out of 904 study
population the predominantly are female which account of 798 (88%), and 106
(12%) were male. 5The Sphincter of Oddi, which regulates the outflow
of bile and pancreatic secretions, is deficient inanomalous union of the
pancreatic biliary duct (AUPBD) due to the long common channel, allowing
two-way regurgitation. Pancreatic biliary reflux can result in various pathological
conditions including choledocholithiasis, cholangitis, gallstones, acute
pancreatitis, bile duct cancer, gallbladder cancer, and pancreatic ductal
carcinoma. [6] In
the present study showed, that bilirubin total concentration was highest in
biliary and lowest in serum. It was significantly higher in biliary compared to
serum (p<0.01). The finding of bacterial proteins in stones, therefore,
confirms these observations. The ability of bacterial β-glucuronidase
enzymes to hydrolyse the bilirubin glucuronide complex thus releasing a poorly
soluble bilirubin has been proposed to explain the formation of pigment stones.
[7], [8] We Showed ALP,
AST, ALT, and T. BILI were high mean significantly increased in biliary males
and positive high correlation more than compared females biliary. Abnormal
liver function tests were most common in patients with choledocholithiasis. An
obstructive pattern with raised alkaline phosphatase values was the most
frequent abnormality, which was similar to the findings of others [9] Our results LFT parameter in this study showed increased in AST, ALT, ALP and
bilirubin total levels are in agreement with Peng et al., 2005 findings. [10] When levels were greatly
increased, all parameters were specific in predicting the presence of bile duct
stones. However, that bilirubin showed an early breakdown, indicating that at a
lower cut-off value bilirubin is no longer specific in predicting CBD stones.
Evaluating role of liver enzymes in prediction of extra liver obstruction in
patients will delay diagnosis of CBD stone. They found that serum level of
bilirubin was the best predictor CBD stenosis due to stone or malignancy. In our study serum level of
bilirubin had higher none significant difference between three study groups compared to biliary levels. [11], [12] As expected, the bilirubin content was
highest in pigment stones (PS). This has been demonstrated in many earlier
studies. The bilirubin in these stones is mostly unconjugated because the
conjugated form is water soluble and excreted through bile. Decreased secretion
of biliary acids, increased secretion of unconjugated bilirubin into the bile,
and infection of the biliary tract are the most important causative factors. [2] That bile duct obstruction due to
stones results in a typical cholestatic biochemical profile, with a greater
rise in ALP than transaminases. Increases AST were likely to equal or exceed
raise ALP in common bile duct stone patients. The possibility of extra hepatic
biliary obstruction should not be overlooked when AST is the predominantly
elevated enzyme. In particular, if pain is associated with a hepatic pattern of LFTs obstructing
biliary stones should be suspected, although pain associated with jaundice
should always suggest gallstone disease, high AST levels, at peak
hyperbilirubinaemia without biliary pain may be misleading, clinicians may
erroneously diagnose a hepatitic illness rather than a cholestatic illness,
since grossly elevated AST levels were found. [13] Acute cholecystitis is the most common complication of cholelithiasis.
Conversely, about (95%) of patients with acute cholecystitis have
cholelithiasis. When a stone becomes impacted in the cystic duct and
persistently obstructs it, acute inflammation results. Bile stasis triggers
release of liver enzymes e.g., serum, ALP, AST and ALT along with serum
bilirubin level. The gallstones block fluid from passing out of the gallbladder
that results in an irritated and swollen gallbladder. [14] These
patients had elevated levels of bile transaminases. In a study done by Chen-Wang and his colleagues; he stated that
hepatocellular injury, (diagnosed clinically by elevation of aminotransferase
and bilirubin levels) was common. The incidence was higher and the
aminotransferase elevations were more marked in those with stones, but some
patients without CBD stones also had a degree of Hepatocellular injury. [15]
Patients with acute
calculus cholecystitis had a serum bilirubin level between 2 to 5 mg/dL with no
CBD abnormality. Also, over one third of patients with calculus cholecystitis
had an elevated bilirubin level with a normal CBD. [16] In some studies, there is a correlation
between the bilirubin concentration and lipid peroxidation in cases of biliary
tract diseases, with the presence of interaction between free radical
reactions, gallbladder formation and the degree of cholecystitis. [17]
It was found in previous study that pigment Stones (PS) was the most common
type of gallstones, and cholesterol seemed to be the major component in all
types of stones. High cholesterol content in cholesterol stone (CS) specific
suggests super saturation of cholesterol in bile consequent to dyslipidemia
(excessive cholesterol and altered lipid metabolism) is an etiological factor.
Higher triglycerides content in mixed stones also suggests that dyslipidemia
plays a key role in its pathogenesis. [18] In the current study positive
correlation was observed in TC, TG, HDL, LDL and VLDL. Some investigators found
positive association between gallstone disease and increased levels of biliary
total cholesterol, Triglycerides, LDL cholesterol, HDL cholesterol and VLDL cholesterol. Interruption
of the enter hepatic circulation of bile acid increases serum triglyceride by
increasing the production of very low density lipoproteins (VLDL). [19]
LDL cholesterol are cleared from the
circulation, increased catabolism of LDL cholesterol can fully explain the
increased cholesterol secretion into bile, the stimulated LDL cholesterol
uptake would in turn had to be explained by an increased cholesterol production
[20]. Highly positive
significant correlations were found between HDL and total cholesterol. The mean
biliary HDL and total cholesterol were higher than in serum lipids, a number of studies have shown that patients with
elevated VLDL, triglyceride had higher than normal rates of bile acid synthesis
and increased rates of cholesterol synthesis. [21]
Total cholesterol,
TAG was significantly higher in cholesterol bile, compared to serum (p<0.001).
A multitude of factors has been postulated in the formation of gallstones, and
amongst them the concept of cholesterol super saturation in the formation of
cholesterol gallstone is the most widely accepted one. The cause of cholesterol
super saturation is usually due to the hyper secretion of cholesterol into the
bile by liver. This may be due to increased DE novo synthesis of cholesterol by
the liver; this hypothesis is given ground by some clinical trials in which it
was observed that use of statin group of drugs decreases the incidence of
gallstone disease. [22]
Super saturation of cholesterol
can also be due to the defect in bile acid synthesis or metabolism. Cholesterol
being a non-polar molecule is transported in clusters of bile acids called
micelles. Increased ratio of cholesterol to bile acid may lead to the bile
being supersaturated with cholesterol, thus predisposing to the formation of
gallstones. The patients with gallstones under study were classified into two
groups depending on their age. The results showed that there was significant
(p< 0.000) increase in concentration of cholesterol, TAG, HDL, LDL and VLDL
in age group (41-45) significant (p<0.000), our results are in disagreement
with (Al-Saadi et al., 2018). In the present study an
increase in bile total cholesterol, TAG, VLDL-C, LDL-C and a decrease HDL-C
were observed. It was reported that an increase in the dietary cholesterol
resulted in an increase in biliary cholesterol secretion in gallstone patient
compared to controls suggesting that dietary cholesterol might be important in
the pathogenesis of cholesterol gallstones [23] These findings support the
hypothesis that hepatic metabolism of cholesterol in gallstone patients differs
from those without stones. Low HDL
cholesterol and a latrogenic biliary profile, multiple factors may lead to
patients to develop cholesterol gallstones and features of the metabolic
syndrome. [24] In male patients showed age range (43 to 45), 8%
very high significant correlation between the relative change in biliary lipids
and serum were found high positive correlation. Some
investigators found a positive association between gallstone disease and
increased levels of serum triacylglycerol, LDL cholesterol and increased HDL
cholesterol. Our results were show increased TC, TG,
LDL cholesterol, V LDL cholesterol and HDL cholesterol in biliary levels
positive very high significant (r
Value= .000) and positive strong
correlation compared to serum. Our study demonstrates that high mean level of
bile triglycerides. Lipid comparison of
biliary and serum showed mean that the concentration of total cholesterol was
about two times more than that in the serum. Lipid comparison of biliary and
serum showed mean that the concentration of TAG was two times more than that in
the serum. Lipid comparison of biliary and serum showed mean that the
concentration of LDL-C was about three times more than that in the serum. Lipid
comparison of biliary and serum showed mean that the concentration of HDL
cholesterol was increased abnormality in the serum. Endogenous
hypertriglyceridemia is a multifactorial disorder of very low density
lipoprotein (VLDL) metabolism, resulting in elevated serum triglyceride (TAG)
concentrations and high levels of high density lipoprotein (HDL) cholesterol. Hypertriglyceridemia
is associated with cardiovascular disease which is prevalence in males higher
than females. This suggests that changes in serum lipid profile are a
possible consequence of the presence of gallstones, especially through biliary
obstruction. Biliary cholesterol saturation is increased in obesity 24and
hypertriglyceridemia is frequently accompanied by obesity. [25] Supersaturated
bile in hypertriglyceridemia may be related to the presence of obesity rather
than to hypertriglyceridemia itself. To date, it is not known whether
gallbladder motility contributes to the increased risk of cholelithiasis to
hypertriglyceridemia. In female were studied, rang of age 20 to 42 years.
Seem to be in accordance with the findings of other investigators who had
reported. Women had
smaller total bile acid pools and increased biliary cholesterol content that
predisposes them to super saturation of cholesterol in the bile pool, resulting
in gallstone formation. 26We found positive correlation significance
between of bile and serum in TC, TAG, LDL, and VLDL. Our results were quite
contrary to the findings of Nadeem et al. 24High cholesterol in bile
as compared to bile acids and bile salts leads to nucleation of cholesterol
which results in the development of gall stones.25. Schirmer has
also reported that cholelithiasis is more common in females higher than males,
while the incidence becomes equal in both gender in older age. [26] The present study had
showed serum female HDL cholesterol higher than level compared to bile patients
and was very high significantly increased (r Value= .000). Other study
is in disagreement in accordance with the findings in (Naseem et al., 2010). Current study showed that in
gallstone disease (GD) patients the serum levels of HDL cholesterol was high
compared to bile patients an unusual observation which could be a result of
poor hepatic uptake of HDL cholesterol in GD patients, our results were in
agreement with (Jaraari et al., 2010). Among female
patients had gallstones, bile lipids levels (total cholesterol, triglyceride,
high density lipoprotein cholesterol were higher than compared to serum except
serum very low density lipoprotein levels was higher than compared to bile
biliary very high significant and positive very strong correlation. In
comparison between serum lipids and biliary lipids, in our study the mean of
serum cholesterol were not high in females (138.85 mg/dl). In our study patients male and females showed prevalence of cholecystitis increasing with age were male higher than compared to females. Cholesterol gallstones occur more frequently in women than in men in every population examined; the present study clearly demonstrates that the effect of exogenous estrogens on biliary lipid composition is the consequence of an increased secretion of cholesterol, and not of a decreased secretion of bile acids. [27] We demonstrated that the ratio of females was higher ratio of males, and this finding is consistent with several similar studies. [28] This difference between the sexes begins during puberty and continues through the fertile years, focusing attention on the effects of female sex hormones. Cholecystitis and cholelithiasis are very common particularly in fatty, fertile and female in their forties. It is prevalence varies with age, sex and ethnic group. [29] We suggest the reason in males were biliary TAG, TC, HDL, and LDL were higher than female. The scavenger receptor, class B type 1 (SR-B1), is multi ligand membrane receptor protein that functions as a physiologically relevant high-density lipoprotein (HDL) receptor whose primary role is to mediate selective uptake or influx of HDL derived cholesterol esters into cells and tissues. SR-B1 also facilitates the efflux of cholesterol from peripheral tissues, including macrophages, back to liver. [30] Biliary lipid absorption by the gall bladder mucosa and the cholesterol content of the gall bladder wall appear to play a role in cholesterol gall stone formation. As the scavenger receptor class B type I (SR- BI) regulates cellular cholesterol uptake, we studied its expression in human and murine gall bladders, its regulation by increased biliary lipid content, and its role in gall stone formation, abnormalities of serum lipoprotein metabolism are known to affect biliary cholesterol secretion [31]. In our results finding mean of serum TC, TAG, LDL and VLDL in male were higher than female, in comparison of lipids between males and females, serum HDL were higher in males than females. Schirmer has reported that cholelithiasis is more common in females higher than males, with female to male ratio of about (4:1), while the incidence becomes equal in both genders in older age. This may be because of the basic hormonal differences between males and females, together with the differences that might exist due to co-expression of sex hormone receptors in the gallbladder of both [31] The present study showed demonstrates a correlation of serum and biliary lipid profiles with gallstones in Libyan population, our results were in agreement with the previous studies. [32] Acute cholecystitis (AC) is a syndrome which entails the continuation of clinic pathological states; one end of this range is acute cholecystitis. In our study showed elevated serum CRP level compared to bile, and observed significantly associated with patients having cholecystitis. Some studies reported that CRP cannot play a suitable role in cholecystitis diagnosis, but can be a factor indicating the severity of cholecystitis usually, pain of the acute cholecystitis is constant and severe with some associated symptoms of including anorexia and vomiting or nausea along with the history of fatty food intolerance estimated >1 hour before the early onset of the pain. [33] CRP up to 2 mg/L because severity of inflammation does not influence the LFT’s parameters and this is comparable with our results (Peng et al., 2005). The study by Juvonen et al. showed that large increases in CRP were associated with both infected bile and gangrene of the gallbladder. The Tokyo guidelines have used CRP of >3 mg/L as one of the diagnostic criteria but have not used it with different cut-offs for diagnosing severity [34] In patients of acute cholecystitis with high levels of CRP, conversion from laparoscopic to open procedure was found to be at higher rates, Prediction of the grade of acute cholecystitis by plasma level of C-reactive protein (Kabul et al., 2015). 5. CONCLUSIONPatients with acute cholecystitis
show abnormal increase in levels of alpha amylase both in blood and bile
samples if patients taken for our study. It appears that estimation of
serum or bile amylase could be added as diagnostic biomarker for patients with
AC, taking patient's case history into consideration (Classic mantra of fat,
forty, fertile, and flatulent) and possibly ruling out acute pancreatitis. Routine investigation of bile
pancreatic alpha amylase in patient having cholecystitis can be used as method
for early detection of cancer lesions. Reason why such levels of
pancreatic alpha enzymes are refluxed into biliary tree and gallbladder in
patients with gallbladder disease should be clarified by further research and
wider scale study. Our study shows abnormal biochemical liver function test of almost patients after cholecystectomy and indicates the presence of acute hepatocellular injury in patients with symptomatic gallstones with cholecystitis in absence of common bile duct stones.
