Hi Allerian,
I'm sorry you've got this added worry too:hug:
April is a long time away still. Is there a possibility of moving the appointment forward? Alternatively you should call your rheumtologist for advice.
My feeling is it is certainly possible that your hypertension is related to early nephritis. Early on in my lupus life I had pretty much the same - mild (around 500mg/24hrs) proteinuria and hypertension ranging about 140/90 to 160/110. At that time, my nephrologist was also pretty relaxed about it and didn't want to biopsy either. However since my other lupus symptoms weren't well controlled and I wanted to cncieve, my rheumatologist added first prednisolone to my plaquenil and later azathioprine, and like magic the blood pressure and urine returned to normal. So - even if treatement 'wasn't needed', my body responded favourably to the more aggressive treatment, and I'm glad about it.
So, my point is, I'd be pushing for at least some intervention. If I remember rightly your lupus is not very well controlled at the moment in other respects either? What meds are you on at the moment?
It would be worth considering an ACE inhibitor to help with the blood pressure. This has the added benifit of renal protection. I wouldn't wait til April to ask aboout this, but try to get onto it ASAP.
The other thing is to consider further lupus drugs. Am I remembering right that your rheumy is considering rixutan (sp:worried

for you? If the proteinuria was the only issue, I can understand holding off doing anything, but in the light of other serious issues, it makes sense to treat 'aggressively' and halt the progression of the lupus.
It is probably sensible if you invest in your own sphygmomanometer and stethescope (yes, they are more accurate than the machines, and I'm presuming you've learnt at med school to use them

) and keep an eye on your blood pressure at home. Also, home urine testing is worth doing, daily if there are abnormalities, and less frequently if everything is OK. Certainly this is what my rheumy and nephrologist wanted. For a long time I kept a graph of proteinuria readings. I think it helped demonstrate to them that it was a real issue, not just a fluke finding. It also helped calm me to know I had it under obstervation and could act if it suddenly got worse.
Let us know how you are getting on?
