Physical disability and Hansen's disease in Brazil in the 21st century: Brief analysis

Risk factors for physical disability in patients with leprosy disease in Yunnan, China: Evidence from a retrospective observational study

BACKGROUND

Leprosy is potentially debilitating. The risk factors related to physical disabilities associated with leprosy disease in Yunnan, China was not clear.

METHODOLOGY/PRINCIPAL FINDINGS

We studied 10644 newly detected leprosy patients from Yunnan, China, from 1990 to 2019. Factors associated with Grade 1 (G1D) and Grade 2 (G2D) physical disabilities or overall physical disabilities (combined G1D and G2D) associated with leprosy were analyzed using multinomial and ordinal logistic regression analyses. The following factors were associated with the development of physical disability in these patients with leprosy: delayed diagnosis [odds ratio (OR): 5.652, 4.399, and 2.275; 95% confidence intervals (CIs): 4.516-7.073, 3.714-5.212, and 2.063-2.509; for ≥ 10, 5-10 y, and 2-5 years, respectively], nerve damage (OR: 3.474 and 2.428; 95% CI: 2.843-4.244, and 1.959-3.008; for 2 and 1 damaged nerves, respectively), WHO classification of PB (OR: 1.759; 95% CI: 1.341-2.307), Ridley-Jopling classification (OR: 1.479, 1.438, 1.522 and 1.239; 95% CI: 1.052-2.079, 1.075-1.923, 1.261-1.838, and 1.072-1.431; for TT, BT, BB, and BL when compared with LL, respectively), advanced age (OR: 1.472 and 2.053; 95% CI: 1.106-1.960 and 1.498-2.814; for 15-59 and over 60 years old, respectively), zero skin lesions (OR: 1.916; 95% CI: 1.522-2.413), leprosy reaction (OR: 1.528; 95% CI: 1.195-1.952), rural occupation (OR: 1.364; 95% CI: 1.128-1.650), Han ethnicity (OR: 1.268; 95% CI: 1.159-1.386), and male sex (OR: 1.128; 95% CI: 1.024-1.243).

CONCLUSIONS

Delayed diagnosis, nerve damage, no skin lesions, WHO and Ridley-Jopling classifications, leprosy reactions, advanced age, rural occupation, Han ethnicity, and male sex were associated with disability in leprosy patients. Identifying risk factors could help to prevent physical disability.

Pure neural leprosy or amyloid neuropathy? Systematic review and clinical case report

OBJECTIVE

To review the literature and to report a clinical case with initial suspicion of pure neural leprosy and final diagnosis of amyloid neuropathy.

METHODS

The study was conducted in two stages. In stage one, a systematic literature review was carried out, with searches performed in the PubMed, Medline, and Lilacs databases, as well as in the leprosy sectoral library of the Virtual Health Library, using the following descriptors: neuritic leprosy, pure neural leprosy, primary neural leprosy, pure neuritic leprosy, amyloid polyneuropathy, amyloid neuropathies, and amyloid polyneuropathy. The search was carried out on May 28, 2020. Clinical trials, cohort studies, cross-sectional studies, clinical cases, and case studies published in Portuguese, English or Spanish between 2010 and 2020 were included. Stage two reports a case with initial suspicion of pure neural leprosy. Laboratory tests, electroneuromyography, ultrasound, and biopsy of the sural nerve were requested.

RESULTS

Twenty-three scientific texts were included. No publications were found that contained both topics together. The challenging diagnosis of pure neural leprosy and the possibility of using auxiliary resources in diagnosis were the most emphasized themes in the studies. In the clinical case, the patient's electroneuromyography showed sensitive and motor polyneuropathy of the lower limbs, which was predominantly sensory and axonal, symmetrical, of moderate intensity, and the mixed type (axonal-demyelinating). Ultrasonography of the sural nerve revealed changes in the contour of the deep fibular nerves; biopsy of the sural nerve showed an accumulation of amorphous eosinophilic material in the nerve path, and Congo red stain showed apple-green birefringence of the deposit under polarized light. The final diagnosis was amyloid neuropathy.

CONCLUSIONS

The final clinical diagnosis was amyloid neuropathy. The diagnosis of pure neural leprosy in endemic areas in Brasil is still a challenge for the health system.

Reviewing the therapeutic management of leprosy in primary care: demand case series referred to a University Hospital in the Midwest region of Brazil

BACKGROUND

Leprosy still represents a negleted public health problem in Brazil. Early and adequate treatment of leprosy, carried out in a primary health network is essential to reduce morbidity and sequelae.

OBJECTIVE

To analyze the therapeutic management of leprosy patients referred from primary healthy services to a specialized service.

METHODS

An analytical retrospective study using medical records and the Notifiable Diseases Information System. Patients diagnosed with leprosy, referred to a specialized outpatient clinic, between 2016 and 2017, in Goiás state, were included. The treatment carried out in the primary health services was compared to the Ministry of Health guidelines.

RESULTS

Two-hundred twenty-five leprosy patients were included, of whom 33.3% were referred by leprosy reactions, 27.1% by sequelae, and 10.2% by suspected recurrence or reinfection. Reviewing the therapeutic management, 123 (54.7%) were considered inadequate, 92 (40.9%) adequate, and 10 (4.4%) inconclusive. Of the 200 multibacillary patients, 39.5% had adequate management. In contrast, 12 (85.1%) out of 14 paucibacillary patients had adequate management (χ² = 11.43 and p < 0.001). Regarding the leprosy reactions and sequelae management, 56.9% and 19.5% were considered inadequate, respectively. There was no difference between the percentage of adequate or inadequate management when considering the Goiás health macroregions (χ² = 7.23; 4 degrees of freedom; p = 0.12).

STUDY LIMITATIONS

Use of recorded data, with incomplete medical records and lack of patient follow-up.

CONCLUSIONS

The study demonstrated the equivocal multibacillaryleprosy management conducted in healthy primary care, with an emphasis on leprosy reactions and sequelae. Training and monitoring the medical staff in the primary healthy services could reduce the morbidity and sequelae of leprosy.

Epidemiological, temporal and spatial dynamics of leprosy in a municipality in northeastern Brazil (2008-2017): an ecological study

INTRODUCTION

Leprosy is a chronic infectious disease caused by Mycobacterium leprae.This study aimed to analyze the epidemiological, temporal, and spatial dynamics ofleprosy in a municipality in northeastern Brazil.

METHODS

This is an ecological study on new leprosy cases in the population of Arapiraca (Alagoas, Northeast Region, Brazil), from 2008 to 2017. Data extracted from a national database were analyzed forepidemiological indicators, factors associated with physical disabilities, and spatialanalysis in the neighborhoods of Arapiraca.

RESULTS

A total of 292 new cases of leprosy were recorded, particularly occurring among the following groups: women, the age group of 46-59 years, brown-skinned individuals, people with less than eight years of schooling, and urban residents; the new cases were also predominantly the tuberculoid form and were of the paucibacillary classification of the disease. Almost 1/3 of the people had some degree of physical disability, which was mainly associated with the group 60 years of age and older, black ethnicity, and the multibacillary clinical form of leprosy. The joinpoint regression showed a stationary temporal behavior of indicators. There was a heterogeneous spatial distribution with active transmission areas, especially in the neighborhoods Primavera, Baixão, Ouro Preto, and downtown.

CONCLUSIONS

The epidemiological indicators revealed complexity in the process of leprosy development. These spatial and temporal studies are relevant to help in the planning, monitoring, and guidance of interventions in the municipality. The spatial analysis showed heterogeneous distribution in the analyzed neighborhoods.

Disabilities in leprosy: an open, retrospective analyses of institutional records

BACKGROUND AND OBJECTIVES

Leprosy remains a leading cause of peripheral neuropathy and disability in the world. Primary objective of the study was to determine the incidence of deformities present at a time of diagnosis and new deformities that patients develop over follow up period.

MATERIAL AND METHODS

An open, retrospective cohort study was performed at a tertiary medical center in western India. Recruitment phase of the study was of 2 years (2009-2010) followed by observation/follow up phase of 7 years till 31st December 2017. New patients with leprosy and released from treatment cases who presented with deformity as defined by WHO disability grade (1998) and subsequently developing new deformities during the follow up period of up to 7 years were included in the study.

RESULTS

The study included 200 leprosy patients. Of the total 254 deformities, 168 (66.14%) deformities were noticed at the moment of diagnosis, 20 (7.87%) deformities occurred during the follow up phase. Of all patients, 21.25% had Grade 1 deformity and 6.31% had Grade 2 or more severe deformity. Deformities of hand were most common in 44.48%, followed by feet 39.76%, and face 15.74% respectively.

LIMITATION OF STUDY

Mode of inclusion of patient was self-reporting during follow up phase so there is possible under reporting of the disabilities.

CONCLUSION

New deformities continue to develop in certain forms of leprosy even after release from treatment. Long-term & regular follow up of patients who have been released from treatment is required.
