I'm pleased my comments were helpful. EWH
Dear Doc , many thanks for your advice . Returned to GUM clinic on monday last and was prescribed doxycycline after test showed WBCs . Symptoms have now gone (although I am obviously completing the course of meds).Your advice was invaluable as I felt very empowered to discuss options with my doc . Thanks again
Welcome to our Forum. Your doctor treated you is just the way the CDC recommends. He sounds well informed. There are several possible reasons for your continued discharge and I will be happy to outline them and suggest an approach. By way of background, all NSU (or NGU as an alternate term) is not due to chlamydia and in a fair number of cases despite rigorous microbiological evaluation, no obvious cause is discovered. Whether such cases in which we cannot identify a cause represent a health hazard is unclear.
Further NSU is typically defined in part by symptoms- do you have burning on urination which accompanies your persisting discharge? The reason I ask is that it is normal for men to have erections during their sleep and following this there may be a small amount of residual discharge present in the morning- this is normal.
Alternatively, your persisting discharge could represent several other processes. Chlamydial treatment failures are rare following azithromycin treatment but they do occur. Alternatively, as the active partner in rectal intercourse fecal bacteria resistant to azithromycin might have been introduced and be the source of your discharge.
My suggestions are:
1. You need to know if this discharge is normal or not- a test for white blood cells, either from a urethral swab (best approach) or testing urine collected just as you start to urinate, would help to sort this out. If no WBCs, no reason for concern.
2. A repeat chlamydial test is reasonable.
3. If there are increased WBCs present or a chlamydial test is positive, the next step would be to treat, this time using doxycycline 100 mg twice daily for 7 days would be the next appropriate step.
I hope this information is helpful. EWH
