Women seeking care in Madagascar for genital discharge ( n =1066) were evaluated for syphilis seroreactivity; bacterial vaginosis (BV) and trichomoniasis. Chlamydial infection was assessed by ligase chain reaction (LCR) and by direct immunofluorescence (IF); gonorrhoea by direct microscopy, culture and LCR. Leucocytes were determined in endocervical smears and in urine using leucocyte esterase dipstick (LED). Gonococcal isolates were tested for minimal inhibitory concentrations. BV was found in 56%, trichomoniasis in 25%, and syphilis in 6% of the women. LCR detected gonorrhoea in 13% and chlamydial infection in 11% of the women. Detection of Gram(-) intracellular diplococci in endocervical smears, and gonococcal culture were respectively 23% and 57% sensitive and 98% and 100% specific compared to LCR. Chlamydia antigen detection by IF was 75% sensitive and 77% specific compared to LCR. Leucocytes in endocervical smears and LED testing lacked precision to detect gonococcal and chlamydial infections. Of 67 gonococcal strains evaluated, 19% were fully susceptible to penicillin, 33% to tetracycline; all were susceptible to ciprofloxacin, ceftriaxone, and spectinomycin. Patients who present with genital discharge in Madagascar should be treated syndromically for gonococcal and chlamydial infections and screened for syphilis. Gonorrhoea should be treated with ciprofloxacin.

To examine sexually transmitted infections (STIs) and associated socio-demographic and behavioural factors in women seeking care for genital discharge syndrome in Antananarivo, Madagascar.One thousand and sixty-six consecutive symptomatic women were interviewed and examined; bacterial vaginosis (BV), vulvovaginal candidiasis, trichomoniasis (TV), cervical infection (CI) due to chlamydial or gonococcal infections, and syphilis seroreactivity were determined by laboratory diagnosis. Associations between STIs and individual characteristics were evaluated using bivariate and logistic regression analyses.The prevalence of BV, TV, CI, and syphilis seroreactivity was, respectively, 85%, 16%, 49%, 16% in 94 prostitutes; 70%, 18%, 30%, 13% in 96 occasional sex traders; and 53%, 24%, 17%, and 4% in 876 general women. CI was independently and positively associated with a symptomatic partner, new sex partner in last 3 months, unfaithful partner, prostitution, joblessness and being25 years old. Syphilis was associated with low schooling, young age at coital debut, sex trading, and1 sex partner in the previous 3 months.These high STI rates and associated characteristics suggest the local vulnerability to rapid HIV spread and show the need for prevention efforts that involve youth, prostitutes, occasional sex traders, sex clients, and men who have concurrent sexual partnerships.

Ulcer material from consecutive patients attending clinics in Antananarivo, Madagascar, was tested using multiplex polymerase chain reaction (M-PCR) to detect Treponema pallidum, Haemophilus ducreyi, and herpes simplex virus. Sera were tested for syphilis and for IgG and IgM antibodies to Chlamydia trachomatis by microimmunofluorescence testing (MIF). By M-PCR, 33% of 196 patients had chancroid, 29% had syphilitic ulcers, and 10% had genital herpes; 32% of the ulcer specimens were M-PCR negative. Compared with M-PCR, syphilis serology was 72% sensitive and 83% specific. The sensitivity of clinical diagnosis of syphilis, chancroid, and genital herpes was 93%, 53%, and 0% and specificity was 20%, 52%, and 99%, respectively. Less schooling was associated with increased prevalence of syphilitic ulcers (P=.001). Sixteen patients (8%) were clinically diagnosed with lymphogranuloma venereum (LGV); 1 plausible case of LGV was found by MIF. In Madagascar, primary care of genital ulcers should include syndromic treatment for syphilis and chancroid.

Data concerning the spectrum and antimicrobial susceptibility of STDs in Madagascar are scarce.Improvement of STD patient management in Madagascar.Assessment of the spectrum of STDs and improvement of therapy.Etiologic study of 400 patients (169 men, 231 women) under consultation at the major STD service in Antananarivo for one or more of the STD syndromes, urethral discharge, cervicovaginal discharge, genital ulcers, or condylomata according to a fixed diagnostic schedule.Of genital ulcers, syphilis accounted for 46%, lymphogranuloma venereum for 24%, chancroid for 16%, and herpes for 1%. Of the syphilis cases, 51% presented as condyloma lata. Discharge was found in 124 men and 210 women. Counting concomitant infections separately, gonorrhea occurred in 69% of the men and 20% of the women with discharges, chlamydia infection in 42% and 52%, trichomoniasis in 9% and 31%, candidiasis in 12% and 30%. Bacterial vaginosis was found in 37% of the women with discharges. In 32% of male and 71% of female gonorrhea cases, there was concurrent chlamydia infection. Infection with HIV 1 or 2 was not detected. Determination of the antibiotic susceptibility of Neisseria gonorrhoea revealed high efficacy of ampicillin, ciprofloxacin, and spectinomycin; but frequent resistance to tetracycline and cotrimoxazole.High priority should be given to the management of infections with chlamydia and with Treponema pallidum as well as to educational measures to increase awareness of genital ulcer disease.Between November 1992 and April 1993, interviews were conducted with 400 patients (169 men, 231 women) aged 14-52 years at the sexually transmitted disease (STD) clinic of the Institut d'Hygiene Sociale in Antananarivo, Madagascar, to determine the pattern of STDs and to improve treatment of the leading STDs. The 400 patients presented with 434 syndromes. 124 men had urethral discharge. 210 women had cervicovaginal discharge. 43 men and 18 women had genital ulcers. Clinicians could not establish a diagnosis in 33 patients. 171 patients had more than one infection. Chlamydia infection was the most common infection associated with another STD (gonorrhea in 22% of men and 11% of women with discharge, trichomoniasis in 2.4% of men and 13% of women, candidiasis in 1.6% of men and 9% of women, and bacterial vaginosis in 15% of women with discharge). Gonorrhea was the most common etiology for male discharge (69%) while chlamydia infection was for female discharge (52%). Women with discharge were more likely than men with discharge to have chlamydia infection (52% vs. 42%), trichomoniasis (30% vs. 9%; p 0.00001), and candidiasis (32% vs. 12%; p 0.00001). 37% of women with discharge had bacterial vaginosis. Chlamydia infection was the most common STD in this population (45%). 32% of male and 71% of female gonorrhea cases also had chlamydia infection. 70 patients had syphilis. 36 of them had secondary stage syphilis. No one had HIV-1 or HIV-2 infection. The most efficacious antibiotics for gonorrhea were ampicillin, ciprofloxacin, and spectinomycin (100% susceptibility). 31% and 26% of isolates were susceptible to tetracycline and cotrimoxazole, respectively. Public facilities in Madagascar do not have the capabilities to diagnosis chlamydia, resulting in many untreated chlamydia cases. These findings stress the need to improve combined treatment of gonorrhea and chlamydia infection and for educational efforts to increase awareness of genital ulcer disease.
