A 9-year-old boy is brought to the clinic because of brightly colored orange urine that he noticed this morning when he urinated after sleeping.
He has had one other urination this morning that was also bright orange in color. He had no pain, frequency or urgency. His mother states that he has been drinking well and feeling well.
He was started on Rifampin yesterday by a local public health official after the child seated next to him at school each day was diagnosed with Neisseria meningititis.
The family history and review of systems are negative including no rash, fever, headache or trauma.
The pertinent physical exam shows a normally developed child with normal vital signs and a negative examination.
The laboratory evaluation showed a bright orange colored urine that had a pH of 6.5, specific gravity of 1.015 with 0-1 white blood cells and was otherwise normal.
The diagnosis of rifampin colored urine was made and the patient and family was reassured.
They were also counseled about symptoms to watch for and the need to seek medical care promptly because of the Neisseriaexposure.
Neisseria meningitis is highly invasive with an attack rate for household contacts of 500-800 times higher than the general population.
Therefore, close contacts should ideally receive chemoprophylaxis within 24 hours of diagnosis of the primary case.
High risk contacts include:
- Household contacts especially young children
- Child care or nursery school contacts within the past 7 days
- Direct exposure to secretions
- Mouth to mouth resuscitation
- Frequently slept or ate in same dwelling
- Passengers seated directly next to the index case for more than 8 hours on airline flights
Recommendations for expanded immunization coverage for Neisseria meningitis were made in 2005.
Most urine color changes are harmless.
They often are due to eating particular food or drugs.
Usually parents can be reassurred that once the child stops ingesting the offending agent, the urine will return to normal color in a short time.
Sometimes infections or other medical problems cause color changes. Some urine color changes occur over time as the urine sits and is exposed to oxygen.
The causes of urine color changes include:
- Red/Burgundy Urine
- Old urine
- Red blood cells
- Food coloring
- Serratia marcescens infection
- Orange Urine
- Congo red dye
- Yellow Urine
- Deep Yellow/Yellow Brown Urine
- Anti-malarial drugs
- Carotene-containing foods
- B-complex vitamins
- Green/Blue Urine
- Blue Diaper Syndrome
- Pseudomonas infection
- Indigo blue dye
- Methylene blue dye
- Copper clasp on diaper holder
- Black Urine
- Old blood
- Hemogentistic urine
Questions for Further Discussion
1. When should health care professionals receive chemoprophylaxis for Neisseria meningitis?
