Update

We had a meeting with the doctors earlier. Long meeting but short story. Kay is showing signs of (continuing) infection. The most likely alternative is one or more fungal infections. Treatment for fungal infections is being broadened. The next most likely alternative is bacterial infection, treatment for which is also being reintroduced. They have also been experimenting with the ventilation this afternoon and have reduced the rate of fluid extraction.

It looks like some or all of this has had an effect already, but the usual caveats apply. Her blood pressure has risen and the support medication is being reduced. Her breathing is a little better. But of course it will take longer before we can be certain of a positive improvement.

My biggest concern really is that Kay has been without an effective immune system for so long now that she's developed an entire potpourri of infections. The medic's thinking seems to be taking them in that direction. There is talk of not one, but potentially a variety of fungal and/or bacterial infections. The ultimate (and potentially only) cure for these things increasingly becomes Kay's own immune system. But of course, the more medication she gets, the more negative load there is on her own system and the harder it becomes for her to assist/take over the fight. Her immune system is showing a little bit of resiliance, her white cell count was 0.8 on Friday, 0.9 yesterday and 1.0 today. Tiny improvements, but more importantly no further drop.
