RESUMO
The aim of this retrospective study carried out from January 2000 to December 2014 was to determine and map the epidemiological evolutionary trends and the clinical forms of leprosy cases notified in Togo. All the 2,630 new leprosy cases notified by all districts to the National Leprosy/Buruli Ulcer Control Program (PNLLUB-Togo) were included. The mean annual incidence was 175 cases with extremes of 73 to 266 cases. The median age of patients was 40 years, and the sex-ratio was 1.13. Children aged 0 to 15 accounted for 5.5% of the cases. The plateau region in the center of the country had the highest annual incidence (around 800 cases). Multibacillary forms accounted for 74.2% of cases. All patients were treated with multidrug therapy (MDT). WHO grade 2 disease was found in 15% of patients and 9.5% were lost to follow-up. Our results confirm that leprosy is no longer a major public health problem in Togo. However, the high incidence of leprosy in some areas of the country, could permit a resurgence of the disease.
Le but de cette étude était de déterminer les tendances épidémiologiques et les formes cliniques des cas notifiés de lèpre au Togo. Il s'agit d'une étude rétrospective portant sur les cas de lèpre notifiés par l'ensemble des districts sanitaires au Programme national de lutte contre la lèpre, l'ulcère de Buruli et le pian du 1er janvier 2000 au 31 décembre 2014. Deux mille six cent trente nouveaux cas de lèpre ont été notifiés. L'incidence annuelle moyenne était de 175 cas avec des extrêmes de 73 et 266 cas. L'âge médian des patients était de 40 ans, et le sex-ratio de 1,13. Les enfants âgés de 0 à 15 ans représentaient 5,5 % des cas. La région des Plateaux dans le centre du pays cumulait l'incidence annuelle la plus élevée (environ 800 cas). Sur le plan clinique, les formes multibacillaires représentaient 74,2 % des cas. Tous les patients étaient traités par polychimiothérapie. L'infirmité de grade 2 de l'OMS était retrouvée chez 15 % des patients, et 9,5 % étaient perdus de vue. Nos résultats confirment que la lèpre n'est plus un problème majeur de santé publique au Togo. On note une incidence élevée de la lèpre dans certaines régions du pays, pouvant faire craindre une recrudescence de la maladie.

The purpose of this study was to describe the epidemiological, clinical, therapeutic profile and the outcome of Buruli ulcer (BU) in the National Reference Center for Buruli ulcer treatment (NRCBUT) in Togo. It was a retrospective and descriptive study of records of patients treated for BU in the NRCBUT between June 2007 and December 2010. During the study period, 119 patients (56.3% males) were treated in the NRCBUT for BU. The median age of patients was 14 years. The proportion of children (< 15 years) was 56.3%. On admission, 85 patients were at ulcer stage and 34 patients at the pre-ulcer stage. BU wounds were mainly located on lower limbs (50.4%), followed by upper limbs (32.6%) and trunk (13.3%). The location of the wounds on the lower limbs were more frequent in patients older than 15 years (P < 0.001), while those on the upper limbs (P = 0.002) and trunk (P = 0.03) were more frequent in patients aged less than 15 years. All patients had received medical treatment which was based on rifampicin-streptomycin combination for eight weeks. This treatment was coupled to surgery in 30 cases. The outcome was punctuated by complications in 7 patients, limb amputation in 3 patients, and sequels in 10 patients. This study confirmed that the BU is the prerogative of young subjects and the exposed areas in the skin facilitates transmission. Apart from these classic features, some unique aspects including the age-dependent distribution are related to the pathogenesis of this disease.
