Introduction

Gallbladder polyps are generally small benign lesions that do not enlarge for years. However, follow-up with ultrasound examination is initially recommended to detect unexpected malignancy. The diagnosis of a gallbladder polyp is generally made with ultrasound examination, and in many instances the polyp is detected while performing the ultrasound examination in the diagnostic workup of a condition not related to the gallbladder [1-7].

Patients and Methods

The occurrence of a gallbladder polyp in a bodybuilder with symptomatic uremia is described, and an educational ultrasound image is provided.

Results

At about the age of 50 years (March, 2022), a professional bodybuilder presented with progressive symptomatic uremia associated with nausea, vomiting, pruritus, and mild anemia. He was not havening reduction in urine output, edema or hypertension. His weight was about 100 Kg, and before his current illness he reported that his bench press single maximum repetition was 140Kg. On the 19th of March, blood urea level was 162 mg /dL and serum creatinine was 6.2 mg /dL. Urinalysis showed 2 plus albuminuria and one plus amorphous urate. Blood calcium and serum electrolytes were within normal ranges, but he had mild hyperphosphatemia with serum phosphorus of 4.9 mg/dL (Normal range 2.4- 4.4mg/dL). Hemoglobin was 10.7 mg/dL (Normal ranges: 11.5-16.5 g/dL). Liver function tests were normal (Total serum bilirubin 0.8 mg/dL, Aspartate aminotransferase (SGOT) 25 iu/L, Alanine aminotransferase (SPOT) 21 iu/L, alkaline phosphatase 284 iu/L)

He reported history of episodes of hyperglycemia that in the case of bodybuilders is generally attributed to growth hor- mone administration in excessive doses. However, the pa- tient was reluctant to provide details about the performance enhancing medications such as anabolic steroids and growth hormone, and he was not confirming or denying the use of such agent. He was simply saying that he was taking protein supplements. Renal ultrasound (Figure-1) confirmed the chronicity of renal failure and showed small kidneys (RK: 8 x 4, cortex 6 mm, LK: 8.2 x 4, cortex 6 mm). The kidneys had hyper-echoic texture with reduced cortical thickness and loss of the corti- cortico-medullary differentiation. There were small cysts on both kidneys, not more than 1, 5 cm in diameter. Abdominal ultrasound also showed small polyp in the gall bladder (Figure 2) and mild enlargement of the prostate with a volume of 27 cm3 (Normally up to 25).

The patient initially required oral prochorperazine 5 mg for two days control the nausea and vomiting, and oral antihistamine plus topical crotamiton 10% to control pruritus. The conservative dietary (Acacia gum supplementation plus very low protein diet) and pharmacological managements were prescribed according to the latest published intestinal dialyis guidelines and included oral iron and folic acid capsule, and calcium carbonate [8-22]. He also received oral finasteride 5 mg daily for the prostatic enlargement. After two weeks, the patient was asymptomatic and blood urea was lowered to 126.4 mg/dL, and the hemoglobin was increased to 11g/d. Ultrasound showed normal prostate size of 20 cm3. Literature review suggested that the addition of essential amino acids and ketoanalogues in the management of chronic renal failure with intestinal dialysis can contribute to its enhancement 25- 26, 2-7]. Therefore, Ketosteril (Fresenius), was prescribed in a low initial dose of three tablets, and was ordered to be brought to the patient from Turkey.

Discussion

Gallbladder polyp has been recognized as a medical condition as early as the 1911. Sand and Mayer reported eight patients with gallbladder polyps who had histopathological diagnosis of papilloma, and seven of them had gallstones [1]. In 1923, Abell reviewed 283 cholecystectomies, and found 8 cases of gallbladder polyps with histopathological diagnosis of adenoma [2]. In 1933, Kirklin reported the initial cholecystographic diagnosis of gallbladder polyps which had histopathological diagnosis of papilloma [3]. In 1934, Wellbrock, reviewed 9550 cholecystectomies, and found 69 cases of gallbladder polyps with histopathological diagnosis of adenoma [4]. However, in 1940, Walters and Snell reported finding gallbladder polyps with histopathological diagnosis of papilloma associated with eholesterolosis in about 8% of cholecystectomies [5]. In 1957, Kozoll and Meyer suggested that gallbladder polyps appear initially an inflammatory reaction to irritating cholesterol and infection. Thereafter, a superficial epithelial adenomatoid hyperplasia ensues within a cholesterol and macrophage-filled stroma with (Cholesterotoma). The occurrence of a significant glandular hyperplasia leads to the formation of a papilloma [6]. Until now, there is no evidence to support that high protein diet per se can cause chronic renal failure. However, nephrocalcinosis caused exogenous vitamin D intoxication was reported to cause renal failure in a bodybuilder athlete [23]. Therefore, an accurate causation of the chronic renal failurecan not be determined.

Carrero etal (2020) emphasized the importance and benefits of fruits and vegetables in patients with chronic renal failure. The intake of fruits and vegetables is associated with a higher fiber intake which can cause a shift in the gut microbiota towards reduced production of uremic toxins. The intake of fruits and vegetables is also associated with lower intake phosphorus, and thus help in controlling hyperphosphataemia [28]. However, the latest published intestinal dialysis guidelines have already suggested intake of fruits and vegetables [22]. The use of Ketoanalogues of essential amino acids in the management of chronic renal failure has been reported as early as the 1970s (Walser, 1978; Bauerdick and colleagues, 1978, Giovannetti etal, 1980) [24-25- 26]. In 1981, Barsotti etal emphasized that treatment of chronic renal failure a very low protein diet plus essential amino acids and ketoanalogues is not associated with reduction of creatinine clearance, while treatment with hemodialysis and free protein intake is associated with reduction of creatinine clearance [27].

Conclusion

The rare association of a gallbladder polyp in a bodybuilder with symptomatic uremia is reported.
