Hemosiderosis pulmonar idiopática, caso clínico en México. Importancia de un diagnóstico y tratamiento oportuno / Idiopathic pulmonary hemosiderosis, clinical case in Mexico. The relevance of performed an early diagnosis and treatment

La hemosiderosis pulmonar idiopática (HPI) es una patología poco frecuente; su distribución geográfica, su incidencia y prevalencia se desconocen de manera exacta a nivel mundial. Tiene una fuerte asociación con condiciones autoinmunes y una adecuada respuesta al tratamiento inmunosupresor. A pesar de ser una patología grave, presenta una tasa de morbilidad y mortalidad mediana, siempre que se realice un diagnóstico y tratamiento precoz. Se presenta el caso clínico de una paciente femenina con diagnóstico de HPI quien cursó con la triada clásica de esta enfermedad: hemoptisis, anemia ferropénica e infiltrados pulmonares difusos. Se descartaron otras causas de hemorragia pulmonar difusa y se realizó el diagnóstico por biopsia pulmonar. Se trató con esteroides sistémicos e inhalados y azatioprina. Tras casi 2 años después del diagnóstico, estando sin tratamiento por 3 meses, presentó una exacerbación con hemorragia pulmonar masiva ocasionando el fallecimiento de la paciente.

Idiopathic pulmonary hemosiderosis (IPH) is a rare pathology; its geographic distribution, incidence and prevalence are not accurately known worldwide. It has a strong association with autoimmune conditions and has an adequate response to immunosuppressive treatment. Despite being a serious pathology, it has a medium morbidity and mortality rate, provided that early diagnosis and treatment is performed. We present the clinical case of a female patient diagnosed with IPH who presented with the classic triad of this disease: hemoptysis, iron deficiency anemia and diffuse pulmonary infiltrates. Other causes of diffuse pulmonary hemorrhage were ruled out and the diagnosis was made by lung biopsy. She was managed with systemic and inhaled steroids and azathioprine. After almost 2 years before the diagnosis, being without treatment for 3 month she had a massive pulmonary hemorrhage, causing the death of the patient.

A Case of Pneumocystis Carinii Pneumonia with Diffuse Pulmonary Hemorrhage / 결핵및호흡기질환

Pneumocystis carinii pneumonia (PCP) is an infectious disease of immune-compromised host. Sometimes it is difficult to differentiate PCP with diffuse pulmonary hemorrhage. Association between PCP and diffuse pulmonary hemorrhage has been reported in 30% of PCP with HIV positive patients. But association between PCP and diffuse pulmonary hemorrhage has not been reported in non-HIV positive patients without any known underlying causes of diffuse pulmonary hemorrhage. We report a case of PCP with diffuse pulmonary hemorrhage in 66 years old male patient. We confirmed PCP and diffuse pulmonary hemorrhage with bronchoalveolar lavage. We can exclude the possible other causes of diffuse pulmonary hemorrhage except PCP. PCP may be one of possible cause of diffuse pulmonary hemorrhage in non-HIV immune compromised patient.
