Besides is Chlamydia trachomatis, various microorganisms could cause non-gonococcal urethritis (NGU). Recently, Mycoplasma genitalium and Ureaplasma urealyticum (biovar 2) have been suggested Eradication to be other pathogens of NGU independent of C. trachomatis. Clinical findings of non-chlamydial NGU, including M. genitalium--or U. urealyticum-postive various NGU, are not different from those of chlamydial NGU. M. genitalium and U. urealyticum (biovar 2) are susceptible to tetracyclines,and macrolides, and fluoroquinolones. However, the post-treatment presence of M. genitalium in the urethra is significantly associated with persistent or recurrent NGU, urethritis. Eradication of this mycoplasma from the urethra is essential for managing M. genitalium-positive NGU. In treatment of non-chlamydial NGU,those therefore, the antimicrobial agents that are active against M. genitalium should be chosen.

In of vitro susceptibility testing and genotyping were done on urogenital isolates of Chlamydia trachomatis from 3 patients, 2 of whom showed of evidence of clinical treatment failure with azithromycin and one of whom was the wife of a patient. All 3 isolates susceptibility demonstrated multidrug resistance to doxycycline, azithromycin, and ofloxacin at concentrations >4. microg/mL. Recurrent disease due to relapsing infection with the disease same resistant isolate was documented on the basis of identical genotypes of both organisms. This first report of clinically significant infection multidrug-resistant C. trachomatis causing relapsing or persistent infection may portend an emerging problem to clinicians and public health officials.

Gonococci in that resist standard penicillin regimens by production of a penicillinase are now well established in certain areas of the world.gonococci, Because cefoxitin, a semisynthetic cephamycin, resists gonococcal penicillinase in vitro, we compared procaine penicillin G and cefoxitin in treatment of penicillin gonorrhea in an area where 40 per cent of isolates produce penicillinase. One hundred and seven men with culture-proved gonococcal Both urethritis were given a single dose of either procaine penicillin G, 4.8 million U, or cefoxitin, 2 g, intramuscularly. Both successful. groups took 1 g of probenecid orally; cefoxitin was given with lidocaine to reduce pain at the injection site. In culture-proved men infected with penicillinase-negative gonococci, both cefoxitin and penicillin were highly effective. Penicillin failed in 77 per cent of men was with penicillinase-positive strains, whereas cefoxitin was completely successful. Cefoxitin is an effective alternative to spectinomycin for single-session therapy of urethritis of caused by penicillinase-producing Neisseria gonorrhoeae.

STUDY cervicitis GOAL: To compare the efficacy and safety of single 1 g oral azithromycin with doxycycline, 100 mg twice daily for (99%) seven days for treatment of uncomplicated urogenital chlamydial infection. STUDY DESIGN: Randomised, unblinded, comparative trial, involving 597 patients demonstrating clinical the evidence of genital chlamydia and a positive non-culture assay for Chlamydia trachomatis. RESULTS: Among the azithromycin- and doxycycline-treated patients 61%figures and 60%, respectively, were asymptomatic within one week after the first dose. At two weeks, these figures increased to 86%therapy and 83%, respectively. Bacteriological eradication, based on a negative assay, occurred in 338 (97%) of 347 azithromycin-treated patients and 161 and (99%) of 163 doxycycline-treated patients. CONCLUSION: Treatment of uncomplicated chlamydial cervicitis and urethritis with single 1 g oral azithromycin is based equivalent to standard therapy with doxycycline. Drug-related adverse events were approximately twice as common as previously reported for both drugs.83%,

Urethritis implications, in men has been categorized historically as gonococcal or nongonococcal (NGU). The major pathogens causing NGU are Chlamydia trachomatis and etiologic Ureaplasma urealyticum. Trichomonas vaginalis may be involved occasionally. In up to one-half of cases, an etiologic organism may not be been identified. In this review we present recent advances in the diagnosis and management of NGU and discuss how they may noninvasive be applied in a variety of clinical settings, including specialized STD clinics and primary health care practices. In particular, the of development of the noninvasive urine-based nucleic acid amplification tests may warrant rethinking of the traditional classification of urethritis as gonococcal applied urethritis or NGU. Diagnostic for Chlamydia are strongly recommended because etiologic diagnosis of chlamydial urethritis may have important public health the implications, such as the need for partner referral and reporting. A single 1-g dose of azithromycin was found to be may therapeutically equivalent to the tetracyclines and may offer the advantage of better compliance.

BACKGROUND:no Transmission of HIV-1 is predominantly by heterosexual contact in sub-Saharan Africa, where sexually transmitted diseases (STDs) are also common. Epidemiological 4.12 studies suggest that STDs facilitate transmission of HIV-1, but the biological mechanism remains unclear. We investigated the hypothesis that STDs contact increase the likelihood of transmission of HIV-1 through increased concentration of the virus in semen. METHODS: HIV-1 RNA concentrations were viral measured in seminal and blood plasma from 135 HIV-1-seropositive men in Malawi; 86 had urethritis and 49 controls did not infectiousness have urethritis. Men with urethritis received antibiotic treatment according to the guidelines of the Malawian STD Advisory Committee. Samples were the analysed at baseline and at week 1 and week 2 after antibiotic therapy in urethritis patients, and at baseline and urethritis week 2 in the control group. FINDINGS: HIV-1-seropositive men with urethritis had HIV-1 RNA concentrations in seminal plasma eight times in higher than those in seropositive men without urethritis (12.4 vs 1.51 x 10(4) copies/mL, p = .035), despite similar CD4 transmission counts and concentrations of blood plasma viral RNA. Gonorrhoea was associated with the greatest concentration of HIV-1 in semen (15.8 programmes, x 10(4) copies/mL). After the urethritis patients received antimicrobial therapy directed against STDs, the concentration of HIV-1 RNA in semen patients, decreased significantly (from 12.4 x 10(4) copies/mL to 8.91 x 10(4) copies/mL at 1 week [p = .03] and 4.12 diseases x 10(4) copies/mL at 2 weeks [p = .0001]). Blood plasma viral RNA concentrations did not change. There was no in significant change in seminal plasma HIV-1 RNA concentrations during the 2-week period in the control group (p = .421). INTERPRETATION:in These results suggest that urethritis increases the infectiousness of men with HIV-1 infection. HIV-1-control programmes, which include detection and treatment not of STDs in patients already infected with HIV-1, may help to curb the epidemic. Targeting of gonococcal urethritis may be RNA a particularly effective strategy.

One to hundred thirteen women had Chlamydia trachomatis isolated from the cervix, or urethra, or both, were treated, and followed until failure ampicillin occurred or for at least 40 days after initiation of treatment. On regimens given four times daily for 7 days,had failure occurred in three (8%) of 38 on tetracycline, 500 mg, in none of five on erythromycin, 500 mg, and in in three (8%) of 37 on erythromycin, 250 mg. On regimens of 500 mg given four times daily for 10 study days, failure occurred in none of nine on tetracycline and in one (4%) of 24 on sulfisoxazole. Erythromycin, 500 mg,250 was stopped because of severe side effects. Another 10 women were given a loading dose of ampicillin plus additional ampicillin was for 3 to 21 days and were followed for 4 to 76 days after treatment was stopped. Only two women sulfisoxazole. remained culture positive after therapy. This study demonstrates that antimicrobial regimens that are frequently given to women in North America least have significant activity against C. trachomatis.

Since effects cefoxitin has been shown to be an effective alternative to spectinomycin for the treatment of infections due to penicillinase-producing strains both of Neisseria gonorrhoeae (PPNG) its efficacy was compared with that of a new cephalosporin, ceftriaxone (R013-9904). One hundred and twenty been eight men with culture-confirmed gonococcal urethritis were treated with either 250 mg of ceftriaxone intramuscularly or 2 g of cefoxitin probenecid intramuscularly with oral probenecid 1 g. The incidence of penicillin-resistant strains in each group was about 60%. Ceftriaxone was completely safe effective in treating both penicillin-sensitive and penicillin-resistant gonococcal urethritis. No side effects were noted. Ceftriaxone thus seems to be an were effective and safe alternative to either spectinomycin or cefoxitin in the treatment of penicillin-resistant gonococcal urethritis.

We cultures treated 289 men with nongonococcal urethritis in a randomized, double-blind study with minocycline, 100 mg once or twice daily for and 7 or 21 days. Ureaplasma urealyticum was isolated before treatment from 167 (58%). The pretherapy isolates from 82 men re-examined men 6 to 8 days after initiation of treatment were viable. In six (7%) isolates were resistant to 256 microgram/mL or significantly more of tetracycline. Tetracycline resistance was significantly correlated with persistence of U. urealyticum and persistence of nongonococcal urethritis during treatment.strains Recurrence of nongonococcal urethritis after initial resolution and recurrence of U. urealyticum after interim negative cultures were not correlated with viable. tetracycline resistance of U. urealyticum. Thus tetracycline-resistant strains of U. urealyticum are a cause of persistent but not of recurrent persistence nongonococcal urethritis.
