This is a challenging case I've been facing, about a 65-year-old lady presenting with weekly recurrences of herpes infection on sacrum and inner thigh (most likely HSV type 2) in the last 20 years. Recurrent vaginal candidiasis coexists. I suspected of acquired immunosuppression and her immunological panel revealed:
leukocytes 1,908
lymphocytes 816
CD4+ 542
CD8+ 166
IgA 44mg/dl
Hb 14,4g%
plat 219,000
Complement levels and other immunoglobulins are within the normal range.
She takes the following drugs continuously (could any of them explain leukopenia + lymphopenia?): omeprazole, ranitidine, amitriptyline, desvenlafaxine, pregabalin, and vaginal ovules of boric acid.
I prescribed imiquimod cream locally, 3 times a week, and she reports parcial improvement of frequency and severity of skin infection.
My doubts now are regarding the continuation of propaedeutics and therapeutics. Any thoughts? Relevant literature?
