ABSTRACT
Drug induced liver injury (DILI) can be can be triggered by many medications including antituberculosis drugs. We present the case of a 37-year-old woman with a smear- positive pulmonary tuberculosis who started treatment with first-line antituberculosis drugs and 4 weeks later presented jaundice, somnolence and a morbilliform generalized rash with progressive neurologic deterioration which had a fatal outcome. Antituberculosis drugs can cause DILI in 2 to 28% of patients and drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) in 1.2%. Acute liver failure (ALF) can occur in 35% of patients with DILI with an overall mortality of 9.7%. If the ALF is unresponsive to medical treatment, liver transplantation has shown promising results and can avoid progression of complications. DILI can be a serious medical condition in patients receiving antituberculosis drugs. If ALF develops and is unresponsive to medical treatment, liver transplantation should be considered as the treatment of choice.
La injuria hepática inducida por fármacos (IHIF) puede ser desencadenado por varios medicamentos incluyendo fármacos anti tuberculosos. Presentamos el caso de una paciente mujer de 37 años con un frotis positivo para tuberculosis pulmonar quien inició tratamiento de primera línea y 4 semanas después, presentó ictericia, somnolencia y un exantema generalizado de tipo morbiliforme con deterioro neurológico progresivo y un desenlace fatal. Los fármacos anti tuberculosos pueden producir injuria inducida por fármacos en 2 a 28% de pacientes y síndrome de DRESS (reacción de sensibilidad a medicamentos con eosinofilia y síntomas sistémicos) en 1,2%. La falla hepática aguda (FHA) en pacientes con injuria hepática inducida por fármacos, puede presentarse en un 35% con una mortalidad del 9,7%. Si la FHA no responde a tratamiento médico, el trasplante hepático ha mostrado resultados positivos y evita la progresión de complicaciones. La IHIF puede ser una condición médica grave en pacientes que reciben medicamentos antituberculosos. Si se desencadena una FHA y no responde a tratamiento médico, debe considerarse con urgencia la posibilidad de trasplante hepático.
ABSTRACT
RESUMEN La tuberculosis multidrogo resistente (TB-MDR) surgió poco después de la introducción de rifampicina en la década de 1960, cuando la resistencia a la isoniazida ya había emergido a mediados de la década de 1950. Sin estos dos medicamentos, la tuberculosis es muy difícil y costosa de tratar, con tasas inaceptablemente altas de fracaso del tratamiento, muertes, pérdidas durante el seguimiento y ningún tratamiento preventivo conocido. La atención global se centró por primera vez en la TB-MDR en la década de 1990 cuando se reportaron brotes hospitalarios con altas tasas de letalidad en muchos países. Los datos de prevalencia para TB-MDR a escala global estaban por primera vez disponibles en 1997. En 2016, 4,1% de aproximadamente 10,4 millones de pacientes nuevos más el 19% de un millón de pacientes tratados previamente, hacían un aproximado de 600 000 personas que desarrollaron TB-MDR o resistencia a la rifampicina; y 250 000 murieron dicho año. Hace diez años, menos del 5% de ellos fueron diagnosticados e iniciaron el tratamiento, aumentando a aproximadamente en 21,6% en 2016, dejando un amplio margen para mejorar. Durante ese mismo período de tiempo, se han fomentado avances para combatir la TB-MDR, incluidos los avances en diagnóstico, terapéutica y atención; descentralizando la atención en el paciente junto con el apoyo social; crecientes mejoras en la prevención de la transmisión; uso cada vez mayor de tratamientos antirretrovirales de alta efectividad; comunicación, abogacía y movilización social; liderazgo y actualización del enfoque de las políticas. Teniendo en cuenta las tendencias epidemiológicas a largo plazo, todos estos factores junto con el financiamiento del Fondo Mundial y otros donantes importantes, sugieren que podemos estar a punto de acelerar la disminución de la morbilidad y mortalidad por TB-MDR. La pobreza extrema, que permite el incremento de la tuberculosis ha disminuido en aproximadamente mil millones de personas en los últimos 25 años. Lo que se necesita ahora es voluntad política por parte de los gobiernos nacionales para aplicar estos avances con diligencia y buscar una mayor reducción de pobreza, empujando las tendencias epidemiológicas más allá del punto de inflexión hacia una pendiente descendente. Todo esto se puede acelerar con un mayor apoyo para la ciencia que conduzca a un mejor diagnóstico, tratamiento y una vacuna efectiva para sostener y acelerar las reducciones reportadas hasta el momento.
ABSTRACT Multidrug-resistant (MDR) tuberculosis (TB) emerged shortly after introduction of rifamycins in the 1960s; isoniazid resistance had already emerged by the mid-1950s. Without these two drugs, tuberculosis is very difficult and costly to treat, with unacceptably high rates of treatment failure, death, loss to follow-up, and no known preventive treatment. Global attention first focused on MDR TB in the early 1990s when nosocomial outbreaks with high case fatality rates were reported in many countries. Prevalence data for MDR TB on a global scale first became available in 1997. In 2016, about 4.1% of estimated ~10.4 million new TB patients plus 19% of ~1 million previously treated patients, that is ~600,000 people develop MDR TB or rifampicin resistant TB; 250,000 die annually. Ten years ago, <5% of them were diagnosed and enrolled on treatment, increasing to about 21.6% in 2016, leaving much room for improvement. Over that same period of time, momentum has been building to combat MDR TB, including advances in diagnostics, therapeutics, and care; decentralizing patient-centered care coupled with social support; growing improvements in prevention of transmission; increasing use of highly effective antiretroviral treatment; communications, advocacy, and social mobilization; leadership and updated policy guidance. Taking into account long-term epidemiological trends, all of these factors coupled with funding from the Global Fund and other major donors, suggest we may be on the verge of accelerating declines in MDR TB morbidity and mortality. Extreme poverty, which allows tuberculosis to flourish, has actually decreased by about one billion people over the past 25 years. What is needed now is political will on the part of national governments to apply these advances diligently and further reductions in poverty, pushing epidemiological trends past the inflection point to the downward slope. All these can be accelerated with increased support for science leading to better diagnosis, treatment and an effective vaccine to sustain and accelerate the meager declines reported thus far.

HIV global pandemic has represented an immense challenge when diagnosing, treating and preventing tuberculosis- the main cause of morbidity and mortality among persons living with HIV/AIDS. The high indexes or early mortality documented in persons with both maladies states the necessity of fast diagnostic tests and opportune treatment because of the atypicity of their presentation, the presence of the immune reconstitution inflammatory syndrome at the beginning of the antirretroviral therapy, and the development of different resistance levels to antituberculosis drugs.
