BACKGROUND Extensively drug-resistant tuberculosis has been reported in 45 countries, including countries with limited resources and a high burden of tuberculosis. We describe the management of extensively drug-resistant tuberculosis and treatment outcomes among patients who were referred for individualized outpatient therapy in Peru. METHODS A total of 810 patients were referred for free individualized therapy, including drug treatment, resective surgery, adverse-event management, and nutritional and psychosocial support. We tested isolates from 651 patients for extensively drug-resistant tuberculosis and developed regimens that included five or more drugs to which the infecting isolate was not resistant. RESULTS Of the 651 patients tested, 48 (7.4%) had extensively drug-resistant tuberculosis; the remaining 603 patients had multidrug-resistant tuberculosis. The patients with extensively drug-resistant tuberculosis had undergone more treatment than the other patients (mean [±SD] number of regimens, 4.2±1.9 vs. 3.2±1.6; P<0.001) and had isolates that were resistant to more drugs (number of drugs, 8.4±1.1 vs. 5.3±1.5; P<0.001). None of the patients with extensively drug-resistant tuberculosis were coinfected with the human immunodeficiency virus (HIV). Patients with extensively drug-resistant tuberculosis received daily, supervised therapy with an average of 5.3±1.3 drugs, including cycloserine, an injectable drug, and a fluoroquinolone. Twenty-nine of these patients (60.4%) completed treatment or were cured, as compared with 400 patients (66.3%) with multidrug-resistant tuberculosis (P=0.36). CONCLUSIONS Extensively drug-resistant tuberculosis can be cured in HIV-negative patients through outpatient treatment, even in those who have received multiple prior courses of therapy for tuberculosis.
Background Multidrug-resistant tuberculosis (MDR-TB) disproportionately affects young adults, including women of childbearing age; however, treatment of MDR-TB during pregnancy is still controversial. This study looks at the treatment and pregnancy outcomes of a ten-year cohort of women who were treated for MDR-TB during pregnancy. Methods A retrospective case series was performed using a standardized data collection form and data from three ranked sources of patient records. All 38 participants were treated with individualized regimes which included second-line tuberculosis medications during pregnancy. We examined the frequency of favorable and adverse outcomes in terms of disease and pregnancy. Results Upon completion of MDR-TB treatment, 61% of the women were cured, 13% died, 13% defaulted, 5% remain in treatment, and 5% failed. Four of the women experienced clinical deterioration of TB during pregnancy. Five of the pregnancies terminated in spontaneous abortions and one child was stillborn. Among the live births, 3 were born with low birth weight, one was premature, and one had fetal distress. Conclusions The rates of success in treating MDR-TB in our cohort are comparable to those of other MDR-TB treatment programs in Peru. The birth outcomes of our cohort are similar to data on the general Peru population. Therefore, we advocate that a woman should be given the option to continue treatment of MDR-TB rather than termination of pregnancy or discontinuation of MDR-TB treatment.
The purpose of this study was to validate the Spanish version of the Berger HIV Stigma Scale in an urban Spanish-speaking population in Peru and create a valid and reliable abridged version of the scale. Participants were HIV-infected adults enrolled in an observational study to examine the effectiveness of a community-based antiretroviral therapy adherence intervention. Approximately half of participants were female, and the median age at enrollment was 30.5 years. The Spanish version of the full HIV Stigma Scale was internally reliable, demonstrated good construct validity, and was sensitive to change over time. The full HIV Stigma Scale was abbreviated by removing items that impaired subscale internal reliability, did not correlate with other subscale items, or demonstrated low factor correlations. The resulting abridged scale contained 21 of the 40 original items and revealed properties similar to the full Spanish version.
From December 2005 to April 2007, we enrolled 60 adults starting antiretroviral therapy (ART) in a health district of Lima, Peru to receive community-based accompaniment with supervised antiretroviral (CASA). Paid community health workers performed twice-daily home visits to directly observe ART and offered additional medical, social and economic support to CASA participants. We matched 60 controls from a neighboring district by age, CD4 and primary referral criteria (TB status, female, neither). Using validated instruments at baseline and 12 months (time of DOT-HAART completion) we measured depression, social support, quality of life, HIV-related stigma and self-efficacy. We compared 12 month clinical and psychosocial outcomes among CASA versus control groups. CASA participants experienced better clinical and psychosocial outcomes at 12 months, including proportion with virologic suppression, increase in social support and reduction in HIV-associated stigma.
The essential role of the nurse as a provider of emotional support in the development or implementation of similar programmes with MDR-TB should, in future, be taken into account.
