Nonbladder related symptoms in patients with interstitial cystitis

Area of Science:

• Urology
• Internal Medicine

Background:

• Interstitial cystitis (IC) is a chronic condition often associated with non-bladder symptoms.
• Previous studies suggest a link between IC and other bodily complaints, but this has not been rigorously tested.
• A validated questionnaire is needed to assess these associated symptoms in IC patients compared to controls.

Purpose of the Study:

• To compare symptom scores in patients with interstitial cystitis (IC) to age-matched controls using the University of Wisconsin (UW) questionnaire.
• To investigate the prevalence of non-bladder related symptoms in IC patients.
• To determine if IC patients report a higher burden of generalized symptoms.

Main Methods:

• 35 female patients diagnosed with interstitial cystitis (IC) participated.
• 35 age-matched healthy female controls were recruited.
• The University of Wisconsin (UW) questionnaire, assessing 7 bladder and 18 non-bladder symptoms, was administered to all participants.

Main Results:

• Interstitial cystitis (IC) patients showed significantly higher scores for bladder-related symptoms (p = 0.0001).
• IC patients reported significantly higher scores for 9 non-bladder symptoms, including pelvic discomfort, backache, dizziness, chest pain, joint aches, nausea, heart pounding, and headache (p < 0.01).
• IC patients did not report higher scores for all non-bladder symptoms, and most had a zero score for many reference symptoms.

Conclusions:

• Patients with interstitial cystitis (IC) experience a higher prevalence of specific non-bladder symptoms, not generalized complaints.
• These findings suggest that the pathophysiology of IC may extend to other organ systems.
• Alternatively, associated factors like sleep disturbances related to IC could contribute to these symptoms.
