Can Uti Make Dogs’ Liver Enzymes Higher?

Liver enzymes are proteins produced by the liver that help carry out various metabolic functions in the body, breaking down and metabolizing substances such as drugs, metabolites, and toxins. In dogs, the most commonly measured liver enzymes in blood tests are ALT, AST, ALP, and GGT.

Liver inflammation in dogs can be caused by fungal infections, causing symptoms such as jaundice, yellowing of the eyes, gums, or skin, and lethargy. High liver enzymes in dogs can indicate various conditions, such as losing appetite, needing to urinate more, vomiting, or being generally lethargic. These signs are not specific to liver disease and can be mild and self-limiting.

Dog food can also affect a dog’s liver health, as kibble can contain dangerous mycotoxins called aflatoxins. Lab reports showing abnormal liver enzyme activity may indicate a variety of conditions, including bladder stones or UTI. Common causes of elevated liver enzymes in dogs include medications like prednisone, Cushing’s disease, liver inflammation such as hepatitis, and certain exam findings suggest an extrahepatic disease is causing increased liver enzyme activities.

In summary, liver enzymes are proteins produced by the liver that help carry out various metabolic functions in the body. Elevated liver enzymes in dogs can indicate various conditions, such as kidney stones, bladder stones, and liver inflammation. It is important to understand the causes, diagnosis, treatment, and prognosis of liver enzyme elevations in dogs to ensure their health and safety.

Can infection cause elevated liver enzymes in dogs?

AST and ALT are enzymes found within liver cells that can be elevated in the blood due to cell damage. Elevations in AST without a similar increase in ALT may indicate muscle damage rather than liver damage. Non-liver diseases, such as heart failure and intestinal inflammation, can indirectly affect the liver and cause increases in ALT. Ingestion of certain toxins or chronic liver inflammation due to infection, immune system overreaction, or genetic disorders can also cause significant ALT elevations.

Cholestatic enzymes, ALP and GGT, are contained in cells that line the bile ducts, which guide the flow of bile from the liver to the small intestine. If bile flow is blocked, these cells increase production of ALP and GGT and release them into the blood. Causes of poor bile flow within the liver include nodular hyperplasia, overwhelming infection, cancerous tumors, and blood vessel abnormalities.

There are several different forms of ALP in dogs, and routine laboratory tests cannot differentiate between them. Dogs under a year old usually have elevated ALP due to bone growth, while dogs taking steroid medication often have elevated ALP due to a form stimulated by steroids. Certain dog breeds, such as Scottish terriers, Siberian huskies, and miniature Schnauzers, also have benign elevations in ALP. Cholestatic enzymes also increase due to the effect of non-liver diseases on the liver, such as pancreatitis, gall bladder disease, intestinal inflammation, and certain endocrine diseases.

Can a dog recover from high liver enzymes?

ALT, the most liver-specific liver enzyme, is found in the cytosol of hepatocytes and is released with increased cell membrane permeability or cell death. It is considered a sensitive and specific marker of liver injury, and severe ALT increases don’t necessarily mean irreversible disease. In dogs, aspartate aminotransferase (AST) is found in both the mitochondria and cytosol of hepatocytes, and is mainly found in the mitochondria. Increases in AST parallel those in ALT, but muscle disease can increase serum AST activity. AST is considered less liver-specific than ALT and is often removed from basic chemistry panels at Texas A and M.

ALP, the least liver-specific and most commonly elevated liver enzyme, causes problems in dogs due to its association with various forms of ALP isoenzymes. Some of these isoforms are not measured by the assay, but they have a trivial contribution to the overall activity of ALP in the serum. In the liver, ALP is bound to the membranes of hepatocytes that form the bile canaliculi and sinusoidal membranes. In cholestasis, the membrane-bound ALP is released into circulation and the synthesis of this enzyme is induced. ALP is considered a sensitive marker of cholestasis in dogs, but because of other isoenzymes, it is not liver-specific.

In summary, liver enzymes like ALT, AST, and ALP play crucial roles in diagnosing liver conditions. While some enzymes may be more liver-specific than others, their role in determining liver damage and regenerative capacity remains a topic of interest.

Can UTI cause liver problems in dogs?

Other problems that can result from this infection include inflammation of the abdominal cavity, bands of scar tissue in the abdomen or intestines, and liver disease. Signs of the infection include blood in the urine, excessive urination, weight loss, and pain in the abdomen or in the area around the kidneys.

Is UTI connected to liver?

Background: Liver cirrhosis is prone to the development of urinary tract infection (UTI). Urine culture is a golden standard for the diagnosis of UTI, but it is often missing in routine clinical practice.

Introduction. Bacterial infection is one of the most significant complications in patients with decompensated liver cirrhosis . Spontaneous bacterial peritonitis (SBP) and urinary tract infection (UTI) are the most common types of bacterial infections in cirrhotic patients . The proportion of UTI in all bacterial infections is 20–25% , and the most common bacteria that cause UTI are Escherichia coli . Bacterial infections confer to a 4-fold increase in the mortality of cirrhosis . However, it remains unclear whether or not UTI increases the risk of mortality in cirrhotic patients .

The golden standard for diagnosis of UTI is a urine culture with significant colony counts of a single organism in a sterile manner . However, urine culture is not frequently used in clinical practice, especially in outpatient settings , for several reasons. First, a urine culture is time consuming requiring 48 hours for the growth and identification of the pathogen and additional 48–72 hours for determining its antimicrobial susceptibility. Second, a large number of cirrhotic patients with UTI are asymptomatic so that a urine culture is often not obtained . Third, the clinicians often use their clinical judgment rather than the standard diagnostic criteria for bacterial infections .

By comparison, urinalysis, microscopy, and bedside urine dipsticks are readily and rapidly available, which allows the clinicians to initiate empiric treatment for suspected UTI while awaiting urine culture results . Fernandez et al. also put forward that uncountable leukocytes can be used as a basis for the diagnosis of UTI, even without the urine culture result .

Can a UTI cause fatty liver?

More recent studies are pointing to the fact that NAFLD may be related to urinary tract infections by pathophysiologic mechanisms distinct from those associated with metabolic syndrome. Nseir et al. recently completed a retrospective case-control review of recurrent UTI in premenopausal women admitted to the hospital . In this study, the incidence of NAFLD was higher in the group of patients with recurrent UTI than in the controls (43. 5% vs. 21. 5%), raising the probability of an association between the two entities. It also showed that patients with recurrent urinary tract infection were more likely to be vitamin D-deficient.

There also seems to be an independent association between NAFLD and vitamin D deficiency ( 32, 104, 105 ), with the degree of deficiency related to the severity of nonalcoholic fatty liver disease . Vitamin D deficiency may independently increase the risk of UTI given that vitamin D is known to stimulate the cathelicidin, an antimicrobial peptide that can be found in the epithelial cells of the urinary bladder ( 97, 106 ).

Multiple studies and even meta-analyses have shown an association between nonalcoholic fatty liver disease and urolithiasis ( 107 – 109 ), potentially illustrating another pathophysiologic mechanism for urinary tract infections in this chronic illness. Finally, contributions from defects in both innate and adaptive immunity cannot be ruled out.

Does inflammation raise liver enzymes?

Elevated liver enzymes often are a sign of inflamed or damaged cells in the liver. Inflamed or injured liver cells leak higher levels of certain chemicals into the bloodstream. These chemicals include liver enzymes that may appear higher than usual on blood tests.

Can dehydration cause high liver enzymes in dogs?

Alanine aminotransferase (ALT) The level of this enzyme often rises when the dog has liver and bile-duct disease. Alkaline Phosphatase (ALKP) Produced by the liver, this enzyme can be elevated as a result of liver disease, Cushing’s syndrome or steroid therapy. Mildly elevated levels can be normal in puppies.

Amylase (AMYL) The pancreas produces this enzyme to help in digestion. High levels can indicate pancreatitis, or inflammation of the pancreas.

Blood Urea Nitrogen (BUN) Urea nitrogen is a waste product created by the liver and excreted by the kidneys. High levels might indicate kidney abnormalities or dehydration, while low levels can signal liver disease. Often compared with creatinine levels (see below).

Can antibiotics cause elevated liver enzymes?

The study examines the impact of antibiotics on liver enzyme elevation in patients with diastolic liver failure (DILI). The maximum levels of AST and ALT were 181. 5U/L and 201. 0 U/L, respectively. After medication stop, all DILI patients naturally recovered without any cases of liver transplantation or death. The most common antibiotics that elevated liver enzyme levels were flomoxef, cetrazole, ceftriaxone, vancomycin, piperacillin/tazobactam, and amoxicillin/clavulanate. Flomoxef was the most common antibiotic that caused DILI, with eight patients out of 24 patients showing elevated liver enzymes more than three times. In outpatients, flomoxef was the most common antibiotic prescribed for outpatients, followed by ceftriaxone, ciprofloxacin, sulfamethoxazole/tripethoprim, isoniazid, and amoxicillin/clavulanate. The prevalence of abnormal liver enzyme was highest in the flomoxef group, with 32 patients showing elevated levels exceeding the upper normal limit. Ciprofloxacin, isoniazid, ceftriaxone, sulfamethoxazole/trimethoprim, and amoxicillin/clavulanate were the most common antibiotics prescribed for outpatients. The study found that the frequency and degree of liver enzyme elevation by antibiotics varied, with flomoxef being the most common.

Can UTI cause liver enzymes to be high?

A previous study has investigated aminotransferase levels during acute pyelonephritis in adult patients, but such a study has not been performed in children . In the present study, we found that many patients with UTI had elevated aminotransferase levels. The prevalence of increased aminotransferase levels in UTI patients without pre-existing liver disease was approximately 20%.

In the present study, patients with increased aminotransferase levels were younger than those with normal levels. Consequently, clinicians should carefully consider hepatic dysfunction in younger patients with UTI.

A previous study has reported neonatal cholestasis in the context of an UTI , but there was no significant increase in total bilirubin level in the present study. Liver dysfunction is not as severe in patients with UTI as in those with cholestasis.

What happens if a dog has a UTI for too long?

If it is not, then it is important to investigate additional issues that may contribute to a persistent UTI. If the infection is not treated, your dog will experience ongoing discomfort. Complications can also occur, such as bladder stones or a kidney infection called pyelonephritis.
