Diagnosis and Treatment of Neisseria gonorrhoeae Infections - Article

ABSTRACT: The most common site of Neisseria gonorrhoeae infection is the urogenital tract. Men with this infection may experience dysuria with penile discharge, and women may have mild vaginal mucopurulent discharge, severe pelvic pain, or no symptoms. Other N. gonorrhoeae infections include anorectal, conjunctival, pharyngeal, and ovarian/uterine. Infections that occur in the neonatal period may cause ophthalmia neonatorum. If left untreated, N. gonorrhoeae infections can disseminate to other areas of the body, which commonly causes synovium and skin infections. Disseminated gonococcal infection presents as a few skin lesions that are limited to the extremities. These legions start as papules and progress into bullae, petechiae, and necrotic lesions. The most commonly infected joints include wrists, ankles, and the joints of the hands and feet. Urogenital N. gonorrhoeae infections can be diagnosed using culture or nonculture (e.g., the nucleic acid amplification test) techniques. When multiple sites are potentially infected, culture is the only approved diagnostic test. Treatments for uncomplicated urogenital, anorectal, or pharyngeal gonococcal infections include cephalosporins and fluoroquinolones. Fluoroquinolones should not be used in patients who live in or may have contracted gonorrhea in Asia, the Pacific islands, or California, or in men who have sex with men. Gonorrhea infection should prompt physicians to test for other sexually transmitted diseases, including human immunodeficiency virus.


Drug Treatment of Common STDs: Part I. Herpes, Syphilis, Urethritis, Chlamydia and Gonorrhea - Article

ABSTRACT: In 1998, the Centers for Disease Control and Prevention released guidelines for the treatment of sexually transmitted diseases. Several treatment advances have been made since the previous guidelines were published. Part I of this two-part article describes current recommendations for the treatment of genital ulcer diseases, urethritis and cervicitis. Treatment advances include effective single-dose regimens for many sexually transmitted diseases and improved therapies for herpes infections. Two single-dose regimens, 1 g of oral azithromycin and 250 mg of intramuscular ceftriaxone, are effective for the treatment of chancroid. A three-day course of 500 mg of oral ciprofloxacin twice daily may be used to treat chancroid in patients who are not pregnant. Parenteral penicillin continues to be the drug of choice for treatment of all stages of syphilis. Three antiviral medications have been shown to provide clinical benefit in the treatment of genital herpes: acyclovir, valacyclovir and famciclovir. Valacyclovir and famciclovir are not yet recommended for use during pregnancy. Azithromycin in a single oral 1-g dose is now a recommended regimen for the treatment of nongonococcal urethritis.


Epididymitis and Orchitis: An Overview - Article

ABSTRACT: Epididymitis and orchitis are commonly seen in the outpatient setting. Men between 14 and 35 years of age are most often affected, and Chlamydia trachomatis and Neisseria gonorrhoeae are the most common pathogens in this age group. In other age groups, coliform bacteria are the primary pathogens. Men with epididymitis and orchitis typically present with a gradual onset of scrotal pain and symptoms of lower urinary tract infection, including fever. This presentation helps differentiate epididymitis and orchitis from testicular torsion, which is a surgical emergency. Typical physical findings include a swollen, tender epididymis or testis located in the normal anatomic position with an intact ipsilateral cremasteric reflex. Laboratory studies, including urethral Gram stain, urinalysis and culture, and polymerase chain reaction assay for C. trachomatis and N. gonorrhoeae, help guide therapy. Initial outpatient therapy is empirical and targets the most common pathogens. When C. trachomatis and N. gonorrhoeae are suspected, ceftriaxone and doxycycline are recommended. When coliform bacteria are suspected, ofloxacin or levofloxacin is recommended.

Diagnosis and Treatment of Urethritis in Men - Article

ABSTRACT: Symptoms of urethritis in men typically include urethral discharge, penile itching or tingling, and dysuria. A diagnosis can be made if at least one of the following is present: discharge, a positive result on a leukocyte esterase test in firstvoid urine, or at least 10 white blood cells per high-power field in urine sediment. The primary pathogens associated with urethritis are Chlamydia trachomatis and Neisseria gonorrhoeae. Racial disparities in the prevalence of sexually transmitted infections persist in the United States, with rates of gonorrhea 40 times higher in black adolescent males than in white adolescent males. Recent studies have focused on identifying causes of nongonococcal urethritis and developing testing for atypical organisms, such as Mycoplasma genitalium and Ureaplasma species. Less common pathogens identified in patients with urethritis include Trichomonas species, adenovirus, and herpes simplex virus. History and examination findings can help distinguish urethritis from other urogenital syndromes, such as epididymitis, orchitis, and prostatitis. The goals of treatment include alleviating symptoms; preventing complications in the patient and his sexual partners; reducing the transmission of coinfections (particularly human immunodeficiency virus); identifying and treating the patient’s contacts; and encouraging behavioral changes that will reduce the risk of recurrence. The combination of azithromycin or doxycycline plus ceftriaxone or cefixime is considered first-line empiric therapy in patients with urethritis. Expedited partner treatment, which involves giving patients prescriptions for partners who have not been examined by the physician, is advocated by the Centers for Disease Control and Prevention and has been approved in many states. There is an association between urethritis and an increased human immunodeficiency virus concentration in semen.
