Specificity of dysuria and discharge complaints and presence of urethritis in male patients attending an STD clinic in Malawi

• OBJECTIVE: This study evaluated the specificity of discharge and dysuria for laboratory confirmed urethritis in symptomatic men presenting to an urban STD clinic in Malawi for treatment and returning for follow up evaluation.METHODS: Clinical treatment trial where consecutive consenting men with urethritis were enrolled and administered a questionnaire, examined, tested, and given one of five urethritis treatments with an efficacy range of 33-95%. Men returning for follow up were questioned, examined, and tested.RESULTS: The presence of both discharge and dysuria were highly specific for laboratory confirmed urethritis (over 90%). Compared with men who had complaints of both discharge and dysuria, men with complaints of dysuria alone were more likely to have reported prior treatment, 72% v 48% (p = 0.003), and less likely to have had gonorrhoea, 64% v 83% (p = 0.04). Men with complaints of discharge or dysuria without evidence of discharge were rare but half of them had documented urethritis. Among men who returned for follow up, 72% had no symptoms of either discharge or dysuria. However, among the 238 men with no symptoms at follow up, laboratory documented gonorrhoea occurred in 9% and non-gonococcal urethritis in 21%.DISCUSSION: In this population of men discharge or dysuria were specific symptoms for urethritis. The symptom of dysuria should be added as an entry criterion for evaluation for urethritis in the World Health Organisation's treatment recommendations. The high prevalence of asymptomatic infection at follow up in a population of men who received suboptimal antimicrobial therapy suggests that the most effective therapy available should be given at the first visit.
