Abstract
Background Purple urinary bag syndrome (PUBS) is a visually striking and rare manifestation of urinary tract infection characterised by purple discolouration of the catheter and the urobag, which are seen primarily in patients who are on long-term indwelling catheter. This rare syndrome results due to the breakdown of indole, a by-product of dietary tryptophan metabolism, to coloured pigments indigo and indirubin by urinary bacteria, which reacts with the catheter and the bag to impart a purple colour. Methods This was a prospective observational study, wherein all cases of PUBS diagnosed between March 2012 and February 2020 were analysed and followed up. Results A total of five patients were presented with PUBS. Among them, four were women, and four were chronically constipated. All of them were elderly and debilitated with either being bed bound or having restricted mobility. Three of them had associated chronic kidney disease. All of them were treated successfully with change of catheters and antibiotics. Conclusion This rare but alarming condition occurs in elderly patients who are on long-term indwelling catheters. The diagnosis is visually apparent, and the treatment may be just a simple change of catheter with oral antibiotics. The awareness may help in correct diagnosis and treatment.

[PMID: 34354830 PMCID: PMC8321942 DOI: 10.1016/j.amsu.2021.102570] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 07/09/2021] [Accepted: 07/13/2021] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Purple Urine Bag Syndrome (PUBS) is an uncommon event that can be described as purple discoloration of urine due to a series of chemical reactions induced by Urinary Tract Infections (UTIs). PUBS has been reported in the past but still remains unrecognized by healthcare givers leading to misdiagnosis and inappropriate management. We report our case alongside a literature review of previously published cases. CASE PRESENTATION We present the first case report of Purple Urine Bag Syndrome in Jordan of a catheterized 80-year-old wheel-chaired female with a history of type 2 Diabetes Mellitus (DM), stage 5 Chronic Kidney Disease (CDK), Hypertension, and ischemic stroke. Her condition was initially misdiagnosed for hematuria but later on was correctly diagnosed with PUBS. She was treated with a course of appropriate antibiotic and by changing her urinary catheter and bag. The patient returned for a follow up visit and her problem resolved with the color of her urine in the urine bag returning back to normal. CLINICAL DISCUSSION PUBS is an uncommon event that occurs in association with UTIs. Such cases are mostly seen in elderly catheterized patients with other risk factors. CONCLUSION Purple Urine Bag Syndrome can be managed by changing urinary catheter, and by the administration of appropriate antibiotics. Such event can be easily misdiagnosed thus leading to unnecessary and consuming measures. Creating a better awareness of this condition among physicians and healthcare givers is essential for better patient outcomes.

Abstract
“Purple urine bag syndrome” (PUBS) is a rare but distressing presentation of urinary tract infection (UTI) among moribund patients on indwelling urinary catheter. A 56-year-old woman with carcinoma of the left breast and metastasis in vertebrae and liver was bed ridden. She was on Foley's catheter for 9 months, with the last catheter changed 3 weeks back. A 75-year-old woman presented with non-Hodgkin's lymphoma for 2 years and moderately differentiated squamous cell carcinoma of the right parotid region (8 months). She experienced fall and fracture of femur, bed ridden, and on Foley's catheter for 7 years. She had facial wound with maggots for 3 days. Both the women developed purple-colored urine with no other symptoms of UTI. No investigations were carried out and they were empirically treated with nitrofurantoin, catheter change reassurance, and increased fluid intake. Urine color was normal by a week. PUBS can be managed easily at home with simple antibiotics, adequate hydration, and family/patient counseling in palliative care settings.

Abstract
Purple urine bag syndrome (PUBS) is rarely observed in clinical practice. The present study aimed to identify the epidemiological trends in PUBS in recent decades. A search of PubMed articles published between 1980 October and 2016 August was conducted, in which 106 articles (174 cases) described PUBS. Of these cases, 58 cases were excluded: 14 cases without mention of gender, 4 cases without description of age, 37 cases without mention of white blood cell (WBC) count, shock status, fever status or description of etiology, and 3 cases without information on mortality. The remaining 116 PUBS cases were collected and analyzed in the present study. The articles were divided into three groups by publication year: 1991 to 2000, 2001 to 2010 and 2011 to 2016. The χ2 test was used for statistical analysis, with P<0.05 (two-tailed) defined as the threshold for significance. Of the total enrolled cases, there were 47 men (40.5%) and 69 women (59.5%), with a mean age ± standard deviation of 75.6±12.8 years. Of these, 98 cases (84.5%) were elderly (≥65 years old). A total of 93.1% of cases had a urine pH >7 while 6.9% of cases had acidic urine (pH <7). Furthermore, although WBC count elevated progressively, the mortality rate of patients with PUBS decreased over subsequent decades. This necessitates the advancement of antibiotics and application of early goal-directed therapy. Additionally, the overall mortality rate of PUBS (1980-2016) was 6.8%, which decreased to 4.3% in the last 5 years (2011-2016). In conclusion, although PUBS has previously been considered a benign process in the majority of indwelling catheterized patients, emphasis is required on early examination and aggressive antibiotic administration.

Abstract
Purple discolouration of urine is not commonly encountered in accident and emergency departments. We report a case of an elderly gentleman on long-term urinary catheter who presented with purple discolouration of urine. He was found to have urinary tract infection caused by the bacteria Proteus mirabilis. The urine became clear after urinary catheter change and antibiotic treatment. This is called the purple urine bag syndrome and emergency physicians should be aware of this uncommon condition and the associated potentially dangerous conditions in order to initiate appropriate management.

Abstract
Purple urine bag syndrome (PUBS) is an infrequent condition, seen mostly in elderly female patients, characterized by an intense purple discoloration of contents of urine bag following long-term indwelling urinary catheterization. The purple discoloration is most often due to the presence of indigo and indirubin pigments which are metabolites of tryptophan. Urinary bacteria with indoxyl sulphatase activity metabolize indoxyl sulphate to produce indigo and indirubin, particularly in alkaline urine. We report an elderly woman with a urinary tract infection and constipation who presented with PUBS. The purple urine disappeared after antibiotic therapy and change of the urine bag. To the best of our knowledge, this is the first case of PUBS reported from this region.

Abstract
Since time immemorial uroscopic analysis has been a staple of diagnostic medicine. It received prominence during the middle ages with the introduction of the matula. Urinary discoloration is generally due to changes in urochrome concentration associated with the presence of other endogenous or exogenous pigments. Observation of urine colors has received less attention due to the advances made in urinalysis. A gamut of urine colors can be seen in urine bags of hospitalized patients that may give clue to presence of infections, medications, poisons, and hemolysis. Although worrisome to the patient, urine discoloration is mostly benign and resolves with removal of the offending agent. Twelve urine bags with discolored urine (and their predisposing causes) have been shown as examples. Urine colors (blue-green, yellow, orange, pink, red, brown, black, white, and purple) and their etiologies have been reviewed following a literature search in these databases: Pubmed, EBSCO, Science Direct, Proquest, Google Scholar, Springer, and Ovid.
