RESUMEN
Leprosy is the oldest disease affecting humankind since ancient times. Despite MDT’s availability for disease curability, vast pockets of multi-bacillary (MB) cases persist in the community. We conducted this study to know the clinico-epidemiological trends of leprosy over four years and five months in this era of the COVID-19 pandemic (C19P). A total of 90 cases were registered; 59 (65.5%) were males, and 31 (34.5%) were females. The majority (69%) of cases were in the 15-45 age groups. Childhood leprosy was detected in 3(3.3%) cases. A history of contact with leprosy patients could be established in 16 (17.8%) cases. The cases comprised 54.5% local inhabitants and 45.5% were migrants. The MB cases 77 out of 90 (85.6%) were in higher proportion than pauci-bacillary (PB) cases. In the clinical spectrum, BL leprosy was most common in 39% of cases, followed by LL and BT leprosy. Thirty-seven (41%) patients were suffering from lepra reactions (LR), and out of them, 59.4% had type 2 reactions (T2R), and the rest had type 1 reactions (T1R). Disabilities were found in a total of 56 (62.2%) cases, and grade 2 disabilities (G2D) were recorded in 25 (44.6%) patients. Ulnar nerve (UN) was most commonly affected nerve in 64.4% of cases, followed by lateral peroneal (LPN) and posterior tibial nerve (PTN). We observed the impact of Covid 19 infection peak C19P in two ways; firstly, during the C19P peak in 2020, there was a drastic fall in total registered cases (TRC) to 4/year against 22/year in pre-C19P with a relative increase in LRs and disabilities. In post-C19P peak periods, not only was there a marked rise in TRC (20/5 months), but LR (50%) and disabilities (75%) also showed a significant rise. A high proportion of MB cases, LRs and disability rates indicate the need for population-based studies and subsequent public health measures for early diagnosis and treatment. Further large sample-sized, in-depth studies can tell the exact impact of C19P on leprosy.
RESUMEN
The need of a validated scale or tool to measure a disease condition, particularity its severity, cannot be over emphasized in clinical research. A validated scale can be used to compare a condition across cultures. Reactions in leprosy continue to be important causes of morbidity both systematic as well as local in the form of pain and disabilities. Measurement of their severity may be helpful in rationalizing their proper management. In this article, the salient features of validated tools to measure type 1 and 2 reactions in leprosy developed during last 7-12 years have been reviewed. The processes of validations are described too. Experience so far with the use of these severity scales to classify and monitor the anti-reaction treatment is limited. There is need to gain more experience in different endemic countries/regions so that duration and doses of anti-reaction agents could be better rationalized. Depending upon the field experience, these severity grading systems may be evolved further.
RESUMEN
Despite leprosy being an eliminated disease from most of the countries in the world including India, it continues to remain as a major burden on public health expenditure. The purpose of this study was to determine the current clinico-epidemiological profile of leprosy at tertiary care health institution in Himachal Pradesh. This retrospective study was conducted in the Department of Dermatology, Indira Gandhi Medical College, Shimla, Himachal Pradesh, India. All patients registered from April 2010 to April 2017 were included in this study. Hospital records of 221 patients were analysed according to age, gender, region of permanent residence, history of contact with leprosy patients, number of patients within state or immigrants from nearby state/country, type of disease-multibacillary (MB) or paucibacillary (PB), type of lepra-reactions and grade of disability patient developed. Out of a total 221 patients majority were in the younger age group of 15-30 years (38.9%), with male predominance (male:female ratio 2.7:1). Majority had MB leprosy (85.5%), and had significant proportion of grade II disability (G2D) compared to national and global data. In clinical disease spectrum, Lepromatous Leprosy (LL) and Borderline lepromatous (BL) leprosy were the most common presentations. Migrants from other states or immigrants from neighbouring country constituted a significant proportion (44/221, 20% approximately). Pure-neuritic disease was diagnosed in 7 (3.2%) patients, childhood cases were only 5 (2.3%) patients, indeterminate leprosy in 3 (1.4%) patients and histoid leprosy in 1 patient (0.004%). To know the exact status of leprosy in the country, knowledge and understanding of the epidemiological profile is an essential pre requisite as it will assess and address public health needs and will help in efficient programme planning and management of leprosy cases in the country. High proportion of MB cases and very high disability percentage shows the need to increase the awareness in the community as well as health care workers so that cases report early, are diagnosed early and managed appropriately so that disabilities become zero in near future. Partnerships among different medical institutions in the state are expected to strengthen the quality referral services and research aimed at eradication.
RESUMEN
BACKGROUND: Lepra reactions occur in 10-30% of patients with leprosy. The standard of treatment is prednisone. However , prolonged steroid use may cause side effects such as osteoporosis, hypertension, hyperlipidemia, atherosclerosis and infections. Fusidic acid targets cytokine systems responsible for the production of Type 1 lepra reaction (T1R) and erythema nodosum leprosum (ENL). It may be given as a steroid-sparing agent in treating lepra reactions. OBJECTIVE: To determine the safety and efficacy of fusidic acid as a steroid-sparing agent in the treatment of Type 1 and Type 2 lepra reactions. METHODS: A randomized controlled trial was conducted on 67 subjects with lepra reactions, aged 18-60, each assigned to receive either prednisone or prednisone + fusidic acid for 12 weeks. Severity of lepra reactions were graded quantitatively using a modified scale by Walker et al and van Brakel et al, and qualitatively using modified National Leprosy Control Program (NLCP) Guidelines at baseline, weeks 2,4,6,8,10 and 12. Doses of prednisone needed to control lepra reactions were also noted at each follow up and statistical analyses were done . Adverse reactions were noted. RESULT: Sixty subjects (89.55%) completed the study. The prednisone + fusidic acid group had lower quantitative and qualitative scores compared to the prednisone group. There were significant differences between the two groups for the quantitative severity scores (p=1.44x10-11) and qualitative severity grading (p=9.36x10-14) at week 12. The mean dose of prednisone was 21.5 mg in the prednisone group and 2 mg in the prednisone + fusidic acid group at week 12 (p=1.01x10-12). No adverse reactions were reported. CONCLUSION: Fusidic acid tablet 250mg/tab two tablets three times a day is an effective and safe steroid-sparing agent for the treatment of lepra reactions.

Background Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae. The principal manifestations are skin lesions and peripheral neuropathy. The aims of the study is to improve the understanding of leprosy cases managed in Penang General Hospital and to analyse the demographics, clinical patterns, treatment regimen and outcome of leprosy in Penang Hospital. Materials and Methods This retrospective study covered a 10-year period from 1997 to 2006. Demographic characteristics, clinical patterns, treatment regimen of leprosy and outcome were analysed. Results A total of 95 patients were diagnosed to have leprosy (prevalence rate of 0.68 per 100,000). The mean age at presentation was 40.4 years ± 17.9 (range from 3 to 91 years old). There were 35 Malays (36.8%), 34 Chinese (35.8%), 5 Indians (5.2%) and 21 others. Patients experienced symptoms for a mean of 21.4 months before being referred to our clinic. Only 29 patients (30.5%) had a family history of leprosy. 34 patients (35.8%) presented with lepromatous leprosy. 95 patients (100%) presented with skin lesions, 61 patients (61.2%) with nerve lesions, 17 patients (17.9%) with deformities and 12 (12.6%) with reactions. The skin lesions occurred predominantly over the lower limbs, face and trunk. 95.8% of skin lesions were hypo/anaesthetic. Common thickened nerves observed were ulnar nerve (40.0%), great auricular nerve (38.9%) and posterior tibialis nerve (25.3%). The lepra reaction rate was 51.6%. Type 1 reaction commonly involved those with borderline spectrum but type 2 reaction commonly involved those with lepromatous spectrum. Common side effects observed with MDT were dapsone induced hemolytic anaemia (10.5%), cutaneous adverse drug reaction (8.4%) and drug induced hepatitis (2.1%). None of them experienced severe drug toxicity. In terms of treatment for leprosy, 71.6% of patients had completed their treatment and 18.9% were still on treatment. 24.1% of patients had their regimen changed because of side effects and drug resistance. 6 patients died (due to unrelated cause) and another 3 patients defaulted treatment. Conclusions Our study showed similar epidemiological findings as other studies except for a higher reaction rate. There was a significant delay in diagnosis in our cohort. Identification of the reasons of delay in diagnosis, and the risk factors of lepra reaction are important in the management of leprosy. Anti-leprotic treatment is relatively safe and effective in treating leprosy.
