Toxicidad pulmonar secundaria a bleomicina. Reporte de un caso / Pulmonary Toxicity Secondary to Bleomycin. A Case Report

La toxicidad pulmonar por antineoplásicos es muy variable dependiente del grupo far-macológico; la bleomicina es uno de los medicamentos en los que se ha reportado este evento. Este citostático puede lesionar el endotelio pulmonar y el epitelio alveolar para llevar a un proceso inflamatorio y fibrótico del intersticio con repercusiones potencial-mente fatales.A continuación, se presenta un caso de enfermedad intersticial tipo neumonía organi-zada asociada a bleomicina en un paciente de 68 años con diagnóstico linfoma Hodg-kin clásico de tipo esclerosis nodular, con estudio imagenológico normal previo al tratamiento

Antineoplastic pulmonary toxicity is highly variable depending on the pharmacological group; bleomycin is one of the drugs in which this event has been reported. This cyto-static can injure the pulmonary endothelium and the alveolar epithelium to lead to an in-flammatory and fibrotic process of the interstitium with potentially fatal repercussions. The following is a case of interstitial disease type organizing pneumonia associated with bleomycin in a 68-year-old patient diagnosed with classical Hodgkin lymphoma of nodular sclerosis type, with imaging study prior to normal treatment

Serum 25-hydroxyvitamin D levels throughout pregnancy: a longitudinal study in healthy and preeclamptic pregnant women.

BACKGROUND: Worldwide there is a high prevalence of 25-hydroxyvitamin D (25OHD) deficiency and has been associated with adverse outcomes during pregnancy. OBJECTIVE: This is a nested, case-control study in a longitudinal cohort to compare the serum 25OHD levels and other biomarkers throughout pregnancy in a group of 20 preeclamptic women and 61 healthy pregnant women. An additional group of 29 healthy non-pregnant women were also studied during the two phases of the menstrual cycle. RESULTS: Mean 25OHD levels in non-pregnant women were 31.9 ng/mL and 34.9 ng/mL during follicular and luteal phase, respectively (P < 0.01). Mean serum 25OHD levels in healthy pregnant women were 26.5, 30.1 and 31.9 ng/mL, at first, second and third trimester, respectively (P < 0.001). The first trimester levels of 25OHD were lower than those of healthy non-pregnant women (P < 0.001), showing a significant recovery at third trimester. In the group of healthy pregnant women, the 25OHD levels were 25.7 ng/mL and 27.2 ng/mL at 3 and 6 months postpartum, respectively; both values were lower than those observed in the non-pregnant women (P < 0.001). In preeclamptic women, 25OHD serum levels were similar to those of healthy pregnant women; nevertheless, they remained almost unchanged throughout pregnancy. CONCLUSION: There were no significant differences between healthy and preeclamptic pregnant women in terms of 25OHD levels throughout the pregnancy. Serum 25OHD levels in non-pregnant women were higher during luteal phase compared with follicular phase. The 25OHD levels of non-pregnant women tended to be higher than those of pregnant women.
