Ref.: (LML) Slit-skin smear positive leprosy
From: Salvatore Noto, Bergamo, Italy
Dear Pieter,
Thank you to Dr Rao for his message (LML 20-08-2021). Slit-skin smear result should report about bacteriological index (BI) and morphological index (MI).
BI is about the total number of bacilli, that is to say:- "solids", "fragmented" and "granular" and, takes years to decrease down to zero; roughly it decreases of one degree of positivity per year. For example a BI 4+ will take four years to become zero.
MI indicates the percentage of the so called "solids" bacilli. These are considered viable bacilli and, they disappear a few months after a successful anti-leprosy treatment.
In the case of Dr Rao's patient, we do not have this information. If he can discuss further with the microscopist, it will be good , if not he should rely on clinical data only. If the patient has a form leprosy that by definition has a high bacterial load like borderline lepromatous or lepromatous leprosy, I suggest continuing treatment for one year more.
Best regards,
S. Noto
