Abstract

Background

The aim of this study was to ascertain the clinical characteristics associated with herpes simplex virus (HSV) urethritis in men and to compare those with chlamydial urethritis.

Methods

We compared clinical and laboratory data from men diagnosed with polymerase chain reaction confirmed HSV urethritis with those of men with chlamydial urethritis presenting to Melbourne Sexual Health Centre between 2000 and 2015.

Results

Eighty HSV urethritis cases were identified: 55 (68%, 95% confidence interval, 58–78) were by HSV-1 and 25 (32%, 95% confidence interval, 22–42) by HSV-2. Compared with chlamydial urethritis, men with HSV urethritis were significantly more likely to report severe dysuria (20% vs 0%, P < 0.01) or constitutional symptoms (15% vs 0%, P < 0.01). Men with HSV urethritis were significantly more likely to have meatitis (62% vs 23%, P < 0.01), genital ulceration (37% vs 0%, P < 0.01), or inguinal lymphadenopathy (30% vs 0%, P < 0.01) but less likely to have urethral discharge (32% vs 69%, P < 0.01). There was no significant difference in the proportion of men who had raised (≥5) polymorphonuclear leukocytes per high-powered field between the two groups (P = 0.46).

Conclusions

The clinical presentation of HSV urethritis in men may differ from those of chlamydial urethritis and guide testing for HSV in men presenting with non-gonococcal urethritis.
