They also found that VEGF regulates cytotrophoblast survival and that expression is deregulated in severe forms of PE.[ 10] Several authors reported an association between some VEGF polymorphisms and PE in selected populations, with some discrepancies [ 3, 11- 14].
In patients with localised self healing CL (LCL) caused by L. major, an increased proportion of CXCR3/CD4+ and/or CD8+ T-cells provided a protective role40, whereas, in severe forms of CL caused by L. braziliensis, increased disease severity occurred secondary to dysregulated CD8+ T-cell cytotoxicity41.
In severe forms we observed a trend for earlier diagnosis throughout 3 consecutive periods from 1980 to 1994.
Objective: The "red complex," composed of Bacteroides forsythus, Porphyromonas gingivalis, and Treponema denticola, is implicated in severe forms of periodontal diseases.
However, in severe forms of retinopathy of prematurity, the stalled blood vessels break through to the surface of the retina and proliferate extensively.
Mutations in NR5A1 have been initially associated with primary adrenal insufficiency and 46,XY gonadal dysgenesis and more recently with less severe phenotypes, including preliminary descriptions in severe forms of male factor infertility.
These results are unexpected, given the observed mortality ratios in severe forms of ARDS [1 3].
Lung involvement is variable, although it has been reported in severe forms of the disease [61].
In severe forms, respiratory failure and cardiovascular collapse have been reported [1 6].
In addition to treatment of the cause, respiratory assistance is necessary in severe forms.
It is mainly characterised by intrahepatic lithiasis and, in severe forms, by bile duct dilatations and rarely, secondary cholangitis.
