Management of Leukorrhoea Without Vaginitis
Diagnostic Confirmation
- The Centers for Disease Control and Prevention recommends that before concluding leukorrhoea is non-pathologic, infectious causes must be systematically excluded through diagnostic testing, including vaginal pH measurement, wet mount microscopy with saline, and KOH preparation 1, 2, 3
- Normal vaginal pH is 3.8-4.5; pH >4.5 suggests bacterial vaginosis or trichomoniasis, as indicated by the Centers for Disease Control and Prevention 1, 2, 4
- Wet mount microscopy with saline should be performed to look for motile trichomonads or clue cells, as recommended by the Centers for Disease Control and Prevention 1, 2, 3
- The whiff test, which identifies a fishy amine odor with KOH application, indicates bacterial vaginosis, according to the Centers for Disease Control and Prevention 1, 2, 5
When Leukorrhoea Alone May Be Significant
- The Centers for Disease Control and Prevention suggests that leukorrhoea (>10 WBCs per high-power field on vaginal fluid microscopy) can indicate cervical inflammation even without vaginitis 6
- If cervicitis is suspected, the Centers for Disease Control and Prevention recommends testing for Chlamydia trachomatis and Neisseria gonorrhoeae using nucleic acid amplification testing (NAAT) 6
Management Approach
- The primary intervention for confirmed non-infectious leukorrhoea is identification and elimination of irritants, such as discontinuing douching, which is associated with bacterial vaginosis risk, as recommended by the Centers for Disease Control and Prevention 7
Critical Pitfalls to Avoid
- The Centers for Disease Control and Prevention advises against empiric antimicrobial therapy when testing fails to identify a cause, as it may lead to more frequent return visits 1, 2, 3
- Up to 50% of women meeting clinical criteria for bacterial vaginosis are asymptomatic, and physiologic discharge is common and requires no treatment, according to the Centers for Disease Control and Prevention 1, 2, 7
