NON-GONOCOCCAL

 URETHRITIS
(NGU)   
Urethritis with an identified pathogen (except gonococcus) is called NGU.
*
NGU is diagnosed by exclusion, that is, failure to find Neisseria gonorrhoeae in urethral specimen from a man with urethritis. 
*
*Urethritis with unidentified pathogen is called NSU.
           NGU, in male, is characterized by:        
           1. Painful micturation (dysuria),             
           2. Frequency of micturation and                      
           3. A scanty mucoid or mucopurulent
               urethral discharge.                             
           4. It has a long incubation period and             
           5. It has a less acute onset.
       NON-GONOCOCCAL URETHRITIS
     (NGU) IN FEMALE
nNGU, in female, mostly asymptomatic, in about 80% cases or associated with vaginal discharge and/or painful micturation.
n
nPost-coitus or intermenstrual bleeding may be a presenting features.

nExamination may reveal mucopurulant cervicitis, contact bleeding from cervix, evidences of PID or no obvious cause. 
n
nPGU, a special variant of NGU, is seen in men who have been successfully treated for gonococcal infection and either develop symptoms shortly after therapy or remain asymptomatic.
n
nC. trachomatis is responsible for 70% to 90% of cases.
n
nBeta-lactum drugs used to treat gonorrhea are largely ineffective against Chlamydia.
n
nBecause of the high (>20%) double infection rate, CDC and WHO recommend that all cases of gonorrhea be treated presumptively for chlamydial infection.         
n
EPIDEMIOLOGY  OF  NGU
NGU patients are:                                                  
nmore often white, better educated,                          
nmore likely to be students and less likely to be unemployed,                                                         
nmembers of the higher socioeconomic status,  
nolder at the age of first intercourse and                     
nhas fewer sex partners.
              Causes of NGU

àChlamydia tracomatis                50%

à‘Non-specific’                             30%
 
àOther causes                              20%


*Ureaplasm urealyticum.

*Mycoplasma genitalium.

*Trichomonas vaginalis.

*Candida albicans.

*Herpes simplex virus.

*Urethral stricture, Foreign bodies                            

    and associated with Reiter’s diseases.
           Complications of NGU
   In male:
Epididymo-orchitis.

   In female:

 Cervicitis may lead to-

 PID: (lower abdominal pain, dyspareunia

                        & post-coital or intermenstrual bleeding).

Cervical neoplasia.

Adverse pregnancy outcome: (tubal damage

                      leading to infertility or ectopic pregnancy).

In both sexes:
nSexually acquired reactive arthropathy 

          (SARA).

nReiter’s syndrome

       (tried of urethritis, conjunctivitis & arthritis).

nOphthalmia neonatorum.

nConjunctivitis in adult.
