My wife, 40yrs old. Oct. 2009 noticed difficulty in climbing stairs and muscle waste.After evaluation, by doctors, was put on 20mg of prednisolone/day, without any established diagonsis. SLE and GBS combination was suspected by the doctors.ANA and antiDNA test were ngative. By June 2010 her condition was rather deteroriating. Moved to another hospital where Polymyositis was diagonised, total CK 3500U/L.After about a week of 60mg of prednisolone/day she was put on 20mg of azathioprine/day with light physiotherapy. By Dec. 2010 she started walking with minimal assistance In March.2011 she had a seizure, walking again became difficult, and on Dec. 31, 2011 she had the third seizure. Never had seizures before now. Ten (10) days ago she came down with herpes- zosters ophthalmicus, HZO (on the right eye). Valtrex was administered for 7days, within 2 days of the attack. The pains has subsided. But persistent itching on the forehead and right side head is making her rather uncomfortable As I write she is on the following medications; Azathiopprine 12mg daily Tegretol 200mg CR daily TryptIzol 1 tab daily at night Vit E 1 capsule daily Nuerovite Forte 1 tab daily Omeprazole 1 tab daily Last CK test showed 780u/l (7800u/l result was obtained in a 10:1 dilution) Walking is still difficult, coupled with; fatigue, pains on the right eye, itching on the forehead and flabby body muscles. Last LFT shows an S-AST value of 107u/l and S-ALT of 77u/l, Total CK is about 1098u/l from700u/l a 6 weeks ago. The LFT printout also indicated possible iron deficiency anaemia. What can we do?
