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.
This detailed case history traces the first 5 years of a psychosocial support group intervention aimed to improve adherence to individualized drug regimens for multidrug-resistant tuberculosis (MDR-TB) in Peru. A total of eight groups were established in metropolitan Lima and two provinces of Peru led by teams of psychiatrists and nurses. The intervention consisted of bi-monthly support groups, recreational excursions, symbolic celebrations, and periodic family workshops. Notably, of the 285 patients who participated in this intervention, only 3.5% defaulted from treatment. Details include the description of services, patient data, major psychosocial difficulties faced by this population, key challenges, and implications. Psychosocial support is a crucial component of treatment for MDR-TB in order to ensure completion of complicated treatment regimens and enable psychosocial rehabilitation after treatment.
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 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.
RationaleA better understanding of the composition of optimal treatment regimens for multidrug-resistant tuberculosis (MDR-TB) is essential for expanding universal access to effective treatment and for developing new therapies for MDR-TB. Analysis of observational data may inform the definition of an optimized regimen.ObjectivesThis study assessed the impact of an aggressive regimen–one containing at least five likely effective drugs, including a fluoroquinolone and injectable–on treatment outcomes in a large MDR-TB patient cohort.MethodsThis was a retrospective cohort study of patients treated in a national outpatient program in Peru between 1999 and 2002. We examined the association between receiving an aggressive regimen and the rate of death.Measurements and Main ResultsIn total, 669 patients were treated with individualized regimens for laboratory-confirmed MDR-TB. Isolates were resistant to a mean of 5.4 (SD 1.7) drugs. Cure or completion was achieved in 66.1% (442) of patients; death occurred in 20.8% (139). Patients who received an aggressive regimen were less likely to die (crude hazard ratio [HR]: 0.62; 95% CI: 0.44,0.89), compared to those who did not receive such a regimen. This association held in analyses adjusted for comorbidities and indicators of severity (adjusted HR: 0.63; 95% CI: 0.43,0.93).ConclusionsThe aggressive regimen is a robust predictor of MDR-TB treatment outcome. TB policy makers and program directors should consider this standard as they design and implement regimens for patients with drug-resistant disease. Furthermore, the aggressive regimen should be considered the standard background regimen when designing randomized trials of treatment for drug-resistant TB.
Multidrug-resistant tuberculosis (MDR-TB) is a global public health problem affecting women of childbearing age. Little is known, however, about the safety of the drugs used to treat MDR-TB during pregnancy. We describe 7 patients who were treated for MDR-TB during pregnancy. These patients had chronic tuberculosis that had caused extensive parenchymal damage and had high-grade resistance to antituberculous drugs. All patients received individualized antituberculous therapy prior to delivery of healthy term infants. Neither obstetrical complications nor perinatal transmission of MDB-TB was observed. One patient experienced treatment failure, and another abandoned therapy. The other 5 patients are currently cured or in treatment and have culture-negative status. In each of these 7 cases, excellent treatment outcomes were obtained for the women and their children. Under certain circumstances, MDR-TB can be successfully treated during pregnancy.
The structured clinical interview for diagnosis (axis 1) according to the Diagnostic and Statistical Manual for Mental Disorders (DSM-III-R) was used to assess psychiatric morbidity in 110 infertile patients. They were divided into two groups according to whether referral to the service of psychosomatic medicine was deemed advisable by the physician in charge. Psychiatric disorders were diagnosed in 39 of 56 (69.6%) patients in the referred group and in 13 of 54 (24.1%) in the non-referred group. Psychiatric morbidity was found in 61.1% of females and 21% of males. Adjustment disorders were found in 59.6% (31/52) of all patients, in 59% (24/39) of patients among the referred group and in 61.5% (8/13) of patients among the non-referred group. Fourteen (67%) of 21 women in the referred group with adjustment disorders suffered from anxiety. In addition, 33.3% of patients in the non-referred group showed important psychological dysfunction, although DSM-III-R criteria were not met. Psychiatric morbidity was significantly associated with the number of treatment cycles and female gender in the whole study population, as well as with the type and length of infertility in the non-referred group. Psychological services in an infertility clinic help to identify at an early stage those individuals who are more likely to be vulnerable. This would enable psychological interventions to be targeted towards those in greater need.
From December 2005 to April 2007, we enrolled 60 adults starting antiretroviral therapy (ART) in Lima, Peru to receive community-based accompaniment with supervised antiretrovirals (CASA), consisting of 12 months of DOT-HAART, as well as microfinance assistance and/or psychosocial support group according to individuals' need. We matched 60 controls from a neighboring district, and assessed final clinical and psychosocial outcomes at 24 months. CASA support was associated with higher rates of virologic suppression and lower mortality. A comprehensive, tailored adherence intervention in the form of community-based DOT-HAART and matched economic and psychosocial support is both feasible and effective for certain individuals in resource-poor settings.
