    Full Text Available The coexistence of leprosy with neurofibromatosis is rare both the diseases present with nerve thickening and skin lesions (patches and nodules. The coexistence of neurofibroma with borderline tuberculoid, lepromatous, histoid, and neuritic leprosy has been reported in the past. We report here a case of borderline lepromatous leprosy coexisting with neurofibromatosis in a 60 year-old male, who presented with neurofibromata and nerve thickening. Histopathology of skin biopsy from the leprosy and neurofibroma nodules confirmed the diagnosis of leprosy and neurofibroma.

    Full Text Available Leprosy is commonly seen over cooler parts of the body and very rarely found over external genitalia because of their warm temperature.We report a case of lepromatous leprosy of prepuce in a 79 years old male who presented with phimosis. Local examination revealed anodule over prepuce and the clinical diagnosis was carcinoma of penis. This case highlights that leprosy should be kept in mind in the differential diagnosis of penile lesions.

    In Brazil, leprosy is a widespread infectious and contagious disease. Clinicians and specialists view leprosy broadly as a systemic infection, since, in its manifestations, it mimics many conditions, such as rheumatic, vascular, ENT, neurological and dermatological diseases. There are few studies that characterize the factors associated with ulcers in leprosy. These injuries should be prevented and treated promptly to avoid serious problems like secondary infections, sepsis, carcinomatous degeneration and amputations. We describe a patient with ulcers on his legs, involving late diagnosis of lepromatous leprosy. PMID:27828650

    Full Text Available Background and Design: Leprosy is a chronic infectious disease caused by Mycobacterium leprae bacillus affecting the skin and peripheral nervous system. Leprosy can lead to severe deformities depending on the extent of the disease. In this study, we aimed to investigate the quality of life of patients with lepromatous leprosy. Materials and Methods: Thirty-five patients with lepromatous leprosy and 35 healthy controls were included in the study. The patients were evaluated with the Turkish version of the Dermatology Life Quality Index (DLQI and the 36-Item Short Form Health Survey (SF-36. The relationship of quality of life with age, gender, marital status, and the grade of the visual impairment was studied and compared with the healthy controls. Results: Total and all the subgroup DLQI scores were higher in the leprosy group than in the control group (p<0.05. The patients with grade 2 visual impairment were more severely affected by the disease with regard to symptoms/feelings and school/work life as compared to the patients with grade 1 visual impairment (p=0.04, p=0.03, respectively. SF-36 physical functioning, physical role functioning, general health perceptions, vitality, social role functioning, and emotional role functioning scores were statistically lower in the patient group than in the control group (p<0.05. Conclusion: We observed that DLQI scores were lower in patients with lepromatous leprosy than in the control group, while increasing impairment in eyes was found to have a negative impact on quality of life. The SF-36 revealed that physical functioning, physical role functioning, general health perceptions, vitality, social role functioning, emotional role functioning, and mental health were negatively influenced in patients with lepromatous leprosy.

    Full Text Available A 25-year-old electrician presented with gradually, asymptomatic swelling on left of the neck since 2 years. The swelling which was initially diagnosed as cervical lymphadenitis by the internist represented the enlarged left great auricular nerve. Cutaneous examination revealed an ill-defined, hypoaesthetic macule with minimal atrophy on the pinna of the left ear. The histopathology of the nerve showed a lepromatous neuritis with bacteriological index (BI of 5+.

    We report on the histologic changes occurring in single cutaneous lesions, from six active lepromatous patients, 1 week following the administration of three daily intradermal injections, 35 micrograms each, of recombinant interferon gamma (rIFN-gamma). Except for a strong induration at the injection site, rIFN-gamma produced no adverse systemic reactions and was able to promote a remarkable influx of T-lymphocytes, mononuclear phagocytes with large nuclei, nonvacuolated cytoplasm, and reduced lysozyme reactivity. Furthermore, despite no clear-cut reduction of mycobacterial dermal burden, bacilli showed a clear increase in the granular appearance. Present findings provide a basis for further elucidation of rIFN-gamma as an additional tool for leprosy treatment.

    Full Text Available Leprosy (Hansen’s disease is a chronic granulomatous infectious disease that primarily affects the peripheral nerves, skin, upper respiratory tract mucosa, eyes and certain other tissues. It is diagnosable and curable if recognized early and treated adequately. A twenty nine-year-old male from Jessore, Bangladesh reported in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh with the complaints of multiple erythematous, large, raised and circumscribed lesions with loss of sensations on different parts of the body, especially distal portions of all four limbs for last eight months. Subsequently he developed ulcers on the anesthetic fingers due to smoking and few ulcerative lesions on both feet. Skin examination revealed multiple erythematous, large nodular lesions on both sides of the cheek and forehead, multiple erythematous, indurated, large plaques with raised margin and central clearing on the trunk, waist and all four limbs, few satellite lesions around the large plaques on the trunk, few hypopigmented patches and plaques on buttock and lower limbs, multiple painless ulcers on dorsal surface of fingers of both hands, both lateral malleoluses and right sole. On examination of peripheral nerves, left great auricular nerve, both ulnar nerves and both common peroneal nerves were moderately enlarged and tender. Slit skin smear for AFB (modified Z-N stain was done and revealed that there were large number of acid and alcohol-fast bacilli arranged in straight and curved parallel bundles with globular masses (cigar-bundle appearance, morphologically resembling Mycobacterium leprae. Skin biopsy for histopathological examination revealed extensive infiltration of macrophages in the dermis, separated from epidermis by narrow grenz zone, with destruction of skin adnexa. Few foci of poorly defined granuloma in dermis were also noted. The patient was managed with rifampicin, clofazimine, dapsone, prednisolone and omeprazole.

    Leprosy is a chronic granulomatous infection of skin and peripheral nerves caused by Mycobacterium leprae and is considered the main infectious cause of disability worldwide. Despite the several studies regarding leprosy, little is known about its effects on microvascular structure and function in vivo. Thus, we have aimed to compare skin capillary structure and functional density, cutaneous vasomotion (spontaneous oscillations of arteriolar diameter), which ensures optimal blood flow distribution to skin capillaries) and cutaneous microvascular blood flow and reactivity between ten men with lepromatous leprosy (without any other comorbidity) and ten age- and gender-matched healthy controls. Orthogonal polarization spectral imaging was used to evaluate skin capillary morphology and functional density and laser Doppler flowmetry to evaluate blood flow, vasomotion and spectral analysis of flowmotion (oscillations of blood flow generated by vasomotion) and microvascular reactivity, in response to iontophoresis of acetylcholine and sodium nitroprusside. The contribution of different frequency components of flowmotion (endothelial, neurogenic, myogenic, respiratory and cardiac) was not statistically different between groups. However, endothelial-dependent and -independent vasodilatations elicited by acetylcholine and sodium nitroprusside iontophoresis, respectively, were significantly reduced in lepromatous leprosy patients compared to controls, characterizing the existence of microvascular dysfunction. These patients also presented a significant increase in the number of capillaries with morphological abnormalities and in the diameters of the dermal papilla and capillary bulk when compared to controls. Our results suggest that lepromatous leprosy causes severe microvascular dysfunction and significant alterations in capillary structure. These structural and functional changes are probably induced by exposure of the microvascular bed to chronic inflammation evoked by

    We are reporting an unusual case of secondary syphilis, in a homosexual male patient, which resembled borderline lepromatous leprosy, and in whom the diagnosis was considered on clinical grounds. The patient also had concomitant HIV infection, with asymptomatic neurosyphilis. His rapid plasma reagin test was reactive in 1:128 dilution. He improved with three standard, weekly injections of benzathine penicillin, along with 2 g of intravenous ceftriaxone daily for 15 days. This case is being reported to highlight the need for a high index of suspicion in diagnosing unusual cases of secondary syphilis, especially in those with concomitant HIV infection. PMID:26692613

    Dapsone hypersensitivity syndrome (DHS) can be classified as a 'drug reaction with eosinophilia and systemic symptoms' (DRESS). It has a variable course, it is not dose dependent and may present with different clinical and laboratory abnormalities. In some cases it may be fatal. We describe a 31 year old man with lepromatous leprosy in whom DHS developed 4 weeks after initiation of World Health Organization multibacillary multidrug therapy (dapsone, clofazimine and rifampin). He had fever, dehydration, diffuse rash, pain on abdominal palpation and inguinal painless lymph nodes. Severe anaemia, abnormal liver function and hyperbilirubinaemia were also found. The patient was treated with prednisone 50 mg daily. There was gradual improvement in the clinical and laboratory signs. We encourage health professionals to be aware of the risk of DHS and to have in mind the development of investigative studies related to HLA and MHC in these patients.

    We have examined a 5th to 6th century inhumation from Great Chesterford, Essex, UK. The incomplete remains are those of a young male, aged around 21-35 years at death. The remains show osteological evidence of lepromatous leprosy (LL) and this was confirmed by lipid biomarker analysis and ancient DNA (aDNA) analysis, which provided evidence for both multi-copy and single copy loci from the Mycobacterium leprae genome. Genotyping showed the strain belonged to the 3I lineage, but the Great Chesterford isolate appeared to be ancestral to 3I strains found in later medieval cases in southern Britain and also continental Europe. While a number of contemporaneous cases exist, at present, this case of leprosy is the earliest radiocarbon dated case in Britain confirmed by both aDNA and lipid biomarkers. Importantly, Strontium and Oxygen isotope analysis suggest that the individual is likely to have originated from outside Britain. This potentially sheds light on the origins of the strain in Britain and its subsequent spread to other parts of the world, including the Americas where the 3I lineage of M. leprae is still found in some southern states of America.

  19. Lepromatous leprosy patients produce antibodies that recognise non-bilayer lipid arrangements containing mycolic acids

    Full Text Available Non-bilayer phospholipid arrangements are three-dimensional structures that form when anionic phospholipids with an intermediate structure of the tubular hexagonal phase II are present in a bilayer of lipids. Antibodies that recognise these arrangements have been described in patients with antiphospholipid syndrome and/or systemic lupus erythematosus and in those with preeclampsia; these antibodies have also been documented in an experimental murine model of lupus, in which they are associated with immunopathology. Here, we demonstrate the presence of antibodies against non-bilayer phospholipid arrangements containing mycolic acids in the sera of lepromatous leprosy (LL patients, but not those of healthy volunteers. The presence of antibodies that recognise these non-bilayer lipid arrangements may contribute to the hypergammaglobulinaemia observed in LL patients. We also found IgM and IgG anti-cardiolipin antibodies in 77% of the patients. This positive correlation between the anti-mycolic-non-bilayer arrangements and anti-cardiolipin antibodies suggests that both types of antibodies are produced by a common mechanism, as was demonstrated in the experimental murine model of lupus, in which there was a correlation between the anti-non-bilayer phospholipid arrangements and anti-cardiolipin antibodies. Antibodies to non-bilayer lipid arrangements may represent a previously unrecognised pathogenic mechanism in LL and the detection of these antibodies may be a tool for the early diagnosis of LL patients.

La respuesta a la terapéutica fue satisfactoria con desaparición de las lesiones cutáneas. La disminución de la respuesta inmunológica celular genera un terreno propicio para la infección de estos gérmenes y al compartir área endémica la asociación entre ambas patologías puede ocurrir.Lepra and Paracoccidioidomycosis are endemic diseases in Argentina. We report a case of a patient with an unusual perianal ulceration and cutaneous manifestations of Hansen's disease. The biopsy of perianal lesion and subsequent studies revealed a disseminated form of paracoccidioidomycosis, as well as skin biopsy and baciloscopic finding diagnostic of Lepromatous Leprosy. The main portal of entry of paracoccidioides is the lung. Hematogenous dissemination of the fungus may occur at this time, with the establishment of metastatic foci in any organ. Anal and perianal lesions are present only in 1.3 to 2.4% of the patients. The pathogenesis of anal lesions remains unclear, it may be secondary from a systemic or a local disease.

    Full Text Available The A.A. started a new series of experiments upon the transmission of Leprosy to man by means of one of the more widespread hematophagi of the hinterland of Brazil, the Triatomidae. Two species of these insects were found naturally infected with Hansen's bacillus in huts of lepers in the interior of the State of Minas Gerais and one of the writers (S.A. upon feeding the same insects on lepromatous cases could obtain two strains of acid-fast bacilli cultures smearing Lowenstein medium with the intestinal contains of the same. The first phase of the experiments lasted five months and the results, partially positive, are here describe. More than one hundred Triatomidae (Triatoma infestans and Panstrongylus megistus bred in the Institute Oswaldo Cruz and fed in normal pigeons until convenient growth were put on lepromatous lesions, which they sucked many times, and them after one or more days they were put to be fed on selected regions of the skin of four negativated cases of leprosy. The arguments in favour and against the possibility of obtaining new lesions of leprosy in such burnet out patients were discussed. The A.A. are not authorized to draw any definite conclusions, but the few facts registered are worth of divulgation, in orther that other workers send their suggestions. Three out of the four volunteers showed moderate local reactions between 1 to 4 days after being sucked by the infected insectes. After five months experiments subcutanous lymph were obtained from the points where the insects have bitten. A very few acid-fast bacilli were found in such material. The patients, being kept in separation from infectious cases, will be followed up during months or a year in order to be detected any suspicious experimental lesions of leprosy.

    More than three million persons are disabled by leprosy worldwide. The main complication of sensory nerve damage is neuropathic ulceration, particularly of the feet. In this review we explored interventions that can prevent and treat secondary damage to skin and limbs. To assess the effects of self-care, dressings and footwear in preventing and healing secondary damage to the skin in persons affected by leprosy. We searched the Cochrane Skin Group Specialised Register (April 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2008), MEDLINE (from 2003 to April 2008), EMBASE (from 2005 to April 2008), CINAHL (1982-2006) and LILACS (1982- April 2008 ) as well as online registers of ongoing trials (April 2008). Randomised controlled trials involving anyone with leprosy and damage to peripheral nerves treated with any measures designed to prevent damage with the aim of healing existing ulcers and preventing development of new ulcers. Two authors assessed trial quality and extracted data. Eight trials with a total of 557 participants were included. The quality of the trials was generally poor. The interventions and outcome measures were diverse. Although three studies that compared zinc tape to more traditional dressings found some benefit, none of these showed a statistically significant effect. One trial indicated that topical ketanserin had a better effect on wound healing than clioquinol cream or zinc paste, RR was 6.00 (95% CI 1.45 to 24.75). We did not combine the results of the two studies that compared topical phenytoin to saline dressing, but both studies found statistically significant effects in favour of phenytoin for healing of ulcer (SMD -2.34; 95% CI -3.30 to -1.39; and SMD -0.79; 95% CI -1.20 to 0.39). Canvas shoes were not much better than PVC-boots, and double rocker shoes did not promote healing much more than below-knee plasters.

Medical College, Gorakhpur from July 2005 to October 2006. This was a prospective case control study in which 20 healthy, age and sex matched people with no evidence of any disease (particularly nerve involvement were included. Limitation: Lesser number of cases were studied. Result: The proximal motor conduction latency was significantly prolonged in both ulnar and common peroneal nerve and proximal motor conduction velocity was also significantly reduced. On examining the values beyond 2S.D. of the control value, distal latency was not affected and only proximal conduction was affected in ulnar nerve. Conclusion: In Type II lepra reaction the motor conduction abnormalities are not prominent. Abnormalities are relatively more marked in the proximal segment.

    Objective. To determine the incidence of bone islands in leprosy patients. Design. X-rays of feet and hands of patients with Hansen`s disease (leprosy) were reviewed retrospectively. A second group of related age- and sex-matched patients who did not have Hansen`s disease was used for control purposes. Controls had undergone hand or foot X-rays during diagnosis of other pathologies. The patients with Hansen`s disease were compared with the control group, and were also analyzed as subgroups with different types of leprosy. The results were subjected to statistical analysis. Patients. Ninety patients with Hansen`s disease were randomly selected for this study. Patients who had had ulcers on hands or feet were excluded from the study. Results and conclusions. Bone islands were demonstrated in 20 patients with Hansen`s disease; no bone islands were observed in the controls. This was statistically significant (P<0.01). Bone islands were only seen in patients with lepromatous leprosy and borderline types but were not demonstrated in patients with tuberculoid leprosy. There was also a statistically significant relationship for a disease duration of 15 years or more. The cause of this raised incidence of enostosis in leprosy patients is not clear, but there may be a genetic predisposition in patients with leprosy, or it may be a side effect of leprosy, especially the lepromatous form.

    A*0101, Cw*04011, and Cw*0602 leprosy patients was observed when compared to the controls. Further haplotype A*1102-B*4006-Cw*1502 was significantly increased among the lepromatous leprosy patients when compared to the controls. It seems that HLA class I alleles play vital roles in disease association/pathogenesis with leprosy among Indians.

    Histoplasmosis is a genus of dimorphic fungi having various varieties of which the commonest one causing infection is Histoplasma capsulatum known to cause histoplasmosis. It has a varied disease spectrum ranging from an acute infection to chronic disease especially in lungs, disseminated disease and cutaneous disorder. Histoplasma capsulatum usually causes subclinical infection and serious infections only manifest in immunocompromised patients. Frank cases of infection are seen in pulmonary histoplasmosis. The spores of these organisms are seen to be strongly associated with droppings of birds and bats. A combination of these droppings and some soil types provide for an excellent environment for the proliferation of spores. Pulmonary histoplasmosis and disseminated disease are very common in AIDS patients and are a great cause of morbidity and mortality in these patients. Primary cutaneous histoplasmosis is very rare and occurs due to penetrating injuries. Once diagnosis is made, the lesions respond very well to oral itraconazole, fluconazole or amphotericicn B. We report a rare case of Cutaneous Histoplasmosis (CHP) in a 70-year-old male with complaints of multiple nodules all over his body in a HIV seronegative and otherwise immunocompetent patient.

    Full Text Available Hundreds of new leprosy cases are still diagnosed in Dakar despite all the efforts in the struggle by the national program for elimination of leprosy by the Institute of Applied Leprosy in Dakar. The aim of our study was to evaluate the epidemiological, clinicopathological and outcome of new cases of leprosy. A prospective study was conducted over a period of one year listing all new cases of leprosy based on clinical diagnosis, bacteriology and histology. 73 new cases were recorded. The sex ratio was 1.5 and the mean age of 39.5 years. Children aged from 0 to 15 years old represented 12%. The clinical forms were rated in order of decreasing frequency Borderline 47.94%, 30.13% lepromatous lepromatous, indeterminate 8.21, borderline lepromatous 6.84, TT: 5.47%, 1.36 and neurological bb%. Neurological signs were enlarged nerve in 50 cases, a neurological deficit in 16 cases and a sensitive deficit in 16 cases. The complications were burns and ulcerations in 10 cases, a claw in 7 cases, a reversal reaction in 7 cases, erythema nodosum in 4 cases and neuritis in 8 cases. The number of new cases mutilated was 24.65%. The smear was positive in 42% and histology contribution in 91.37% of cases. Our study highlights the significant number of patients with multibacillary contagious, affected children, the high proportion of disability grade 2/OMS reflecting the delay in diagnosis. This delay is due to ignorance, to traditional treatments and low socio-economic status and lack of trained diagnostic teams in different areas apart from referral centres.

    Full Text Available Background: Leprosy is a chronic granulomatous disease and affects many internal organs in addition to the skin and peripheral nerves. Endocrine dysfunction is often silent and is often missed in patients of leprosy leading to significant morbidity. We studied the presence of occult endocrine disorders in leprosy patients and compared the same with disease parameters. Materials and Methods: We evaluated 40 patients of leprosy (aged 18-70 years, any duration in this cross-sectional, observational study. All subjects were assessed for pituitary, thyroid, adrenal, gonadal function, and dynamic testing was done when deemed necessary. The participants were divided into two groups: Group 1 (Leprosy, n = 40 and Group 2 (Controls, n = 20 and the data were analyzed with appropriate statistical tests. Results: The study participants (35 males, 5 females had a mean age of 36.4 ± 11.3 years, and duration of the disease was 2.5 ± 5.5 years. Eleven out of 40 patients showed results consistent with an endocrine disorder, including subclinical hypothyroidism (n = 4, sick euthyroid syndrome (n = 3, growth hormone (GH deficiency (n = 2, primary hypogonadism (n = 2 and secondary hypogonadism in one patient. One patient had partial hypopituitarism (GH deficiency and secondary hypogonadism and none of the controls showed any hormonal dysfunction. Testosterone levels showed inverse correlation with the number of skin patches (P = 0.0006. Conclusion: Occult endocrine dysfunction is seen in a quarter of patients with leprosy. Thyroid and gonadal axes abnormalities are common, and the severity is more in lepromatous forms of the disease. Further large studies are required to confirm the findings observed in our study.

    Full Text Available It is important to understand the mechanisms that enable peripheral neurons to regenerate after nerve injury in order to identify methods of improving this regeneration. Therefore, we studied nerve regeneration and sensory impairment recovery in the cutaneous lesions of leprosy patients (LPs before and after treatment with multidrug therapy (MDT. The skin lesion sensory test results were compared to the histopathological and immunohistochemical protein gene product (PGP 9.5 and the p75 nerve growth factor receptors (NGFr findings. The cutaneous neural occupation ratio (CNOR was evaluated for both neural markers. Thermal and pain sensations were the most frequently affected functions at the first visit and the most frequently recovered functions after MDT. The presence of a high cutaneous nerve damage index did not prevent the recovery of any type of sensory function. The CNOR was calculated for each biopsy, according to the presence of PGP and NGFr-immunostained fibres and it was not significantly different before or after the MDT. We observed a variable influence of MDT in the recovery from sensory impairment in the cutaneous lesions of LPs. Nociception and cold thermosensation were the most recovered sensations. The recovery of sensation in the skin lesions appeared to be associated with subsiding inflammation rather than with the regenerative activity of nerve fibres.

    Full Text Available Pretty leprosy is one of the rare severe forms of lepromatous leprosy. It is a reaction pattern that occurs in untreated pure primitive diffuse lepromatous leprosy or lepromatous leprosy. The skin of the patient is diffusely infiltrated and shiny, so that natural wrinkles are obliterated. It generates a moist and myxoedematous complexion imparting a healthy aspect to the patient. Thus the disease got the name. In this review we have reviewed almost all available literature to point more light toward the clinical variant pretty leprosy. A search was made in PubMed central to know the availability of information about pretty leprosy, but the response was nil for pretty leprosy. 37 articles were spotted in PubMed media on Lucioleprosy; 3 review articles are present and the rest were case reports.

    Nerve biopsy examination is an important auxiliary procedure for diagnosing pure neural leprosy (PNL). When acid-fast bacilli (AFB) are not detected in the nerve sample, the value of other nonspecific histological alterations should be considered along with pertinent clinical, electroneuromyographical and laboratory data (the detection of Mycobacterium leprae DNA with polymerase chain reaction and the detection of serum anti-phenolic glycolipid 1 antibodies) to support a possible or probable PNL diagnosis. Three hundred forty nerve samples [144 from PNL patients and 196 from patients with non-leprosy peripheral neuropathies (NLN)] were examined. Both AFB-negative and AFB-positive PNL samples had more frequent histopathological alterations (epithelioid granulomas, mononuclear infiltrates, fibrosis, perineurial and subperineurial oedema and decreased numbers of myelinated fibres) than the NLN group. Multivariate analysis revealed that independently, mononuclear infiltrate and perineurial fibrosis were more common in the PNL group and were able to correctly classify AFB-negative PNL samples. These results indicate that even in the absence of AFB, these histopathological nerve alterations may justify a PNL diagnosis when observed in conjunction with pertinent clinical, epidemiological and laboratory data.

    Full Text Available Although immunopathology dictates clinical outcome in leprosy, the dynamics of early and chronic infection are poorly defined. In the tuberculoid region of the spectrum, Mycobacterium leprae growth is restricted yet a severe granulomatous lesion can occur. The evolution and maintenance of chronic inflammatory processes like those observed in the leprosy granuloma involve an ongoing network of communications via cytokines. IL-10 has immunosuppressive properties and IL-10 genetic variants have been associated with leprosy development and reactions.The role of IL-10 in resistance and inflammation in leprosy was investigated using Mycobacterium leprae infection of mice deficient in IL-10 (IL-10-/-, as well as mice deficient in both inducible nitric oxide synthase (NOS2-/- and IL-10 (10NOS2-/-. Although a lack of IL-10 did not affect M. leprae multiplication in the footpads (FP, inflammation increased from C57Bl/6 (B6nerves containing CD4+ cells were present in 10NOS2-/- FP.The 10NOS2-/- strain offers insight on the regulation of granuloma formation and maintenance by immune modulators in the resistant forms of leprosy and presents a new model for investigating the pathogenesis of neurological involvement.

    Full Text Available Objective: Leprosy is a contagious chronic granulomatous disease and commonly affects the eyes and the internal organs. Leprosy can be classified according to the level of immune response. Leprosy is a disease that is associated with defects in cellular immunity. This is why we have investigated the leprosy patients that were referred to our hospital for chronic hepatitis B and C co-infections. Methods: Fifty patients who were treated in the leprosy unit of Elazığ Research and Training hospital between the dates of June-December 2011 were enrolled to this descriptive study. Macro ELISA assay was performed for Hepatitis B,C and HIV. Results: Fifty patients who were treated in the leprosy unit of our hospital participated in the study. A total of 8% HBsAg presence was noted. A total of 16 Anti HCV presence was noted in the patient group. Anti HCV positivity was determined at seven of 14 patients with tuberculoid form leprosy (50% and nine of 33 lepromatous leprosy form (27,2%. Conclusion: In conclusion, leprosy patients, especially lepromatous leprosy group, are immunologically vulnerable to HBV and HCV co-infections. Thus, physicians should be aware of HBV coinfections in these patients and education should be given to patients to increase their knowledge regarding risky situations for transmission of the disease.

    Full Text Available Earlier studies have shown sonographic enlargement of the ulnar nerve in patients with Hansen's neuropathy. The present study was performed to determine whether sonography or electrophysiological studies can detect the specific site of ulnar nerve pathology in leprosy.Eighteen patients (thirty arms with Hansen's disease and an ulnar neuropathy of whom 66% had borderline tuberculoid (BT, 27% lepromatous leprosy (LL and 7% mid-borderline (BB leprosy were included in the study. Cross-sectional area (CSA of ulnar nerve was measured every two centimeters from wrist to medial epicondyle and from there to axilla. All patients underwent standard motor and sensory nerve conduction studies of the ulnar nerve. Thirty age and sex matched controls underwent similar ulnar nerve CSA measurements and conduction studies.Ulnar nerve was clinically palpable in 19 of the 30 arms of patients. Motor and sensory nerve conduction studies of the ulnar nerve showed a reduced compound motor action potential and sensory nerve action potential amplitude in all patients. Motor Conduction Velocity (MCV in patients were slower in comparison to controls, especially at the elbow and upper arm, but unable to exactly locate the site of the lesion. In comparison to controls the ulnar nerveCSA was larger in the whole arm in patients and quite specific the maximum enlargement was seen between nulnar sulcus and axilla, peaking at four centimeters above the sulcus.A unique sonographic pattern of nerve enlargement is noted in patients with ulnar neuropathy due to Hansen's disease, while this was not the case for the technique used until now, the electrodiagnostic testing. The enlargement starts at ulnar sulcus and is maximum four centimeters above the medial epicondyle and starts reducing further along the tract. This characteristic finding can help especially in diagnosing pure neuritic type of Hansen's disease, in which skin lesions are absent, and alsoto differentiate leprosy from

    -alcohol-resistant bacilli (AARB called Mycobacterium leprae. Infection has a long incubation period and mainly affects skin, mucous membranes and peripheral nerves. Its clinical presentation comprises two polar types, lepromatous leprosy (LL, tuberculoid leprosy (TL and three borderline expressions. Here we report a case of a 36 year-old male patient, who suffers since two years ago skin lesions characterized by hyperchromic macules that progressed to nodules, initially in hands and feet, then spread throughout the body, without respect of palm of hands and feet. Preceded by Dengue infection (20 days before, and a histopathological diagnosis as Glomangiosarcoma. Upon admission, the patient had countless indurated, multiform and confluent nodular lesions, associated to unaltered superficial or deep sensitivity or neuromuscular symptoms. Radiological studies from thorax, abdomen and pelvis showed no musculoskeletal or visceral lesions without nodal involvement. The second biopsy reported chronic inflammation, few lymphocytic infiltrate, foamy macrophages, countless and slightly curved intracellular (macrophages AARB. Lepromin test was negative reported. The final diagnosis was lepromatous leprosy. Triple multitherapy (dapsone, rifampicin, clofazimine was prescribed and two months later, evidence of improvement in the number and size of lesions was observed. Early diagnoses through clinical, histopathological, immunological tests are central to the broader context of clinical presentations in Leprosy.

    Lepromatous leprosy (LL) represents the highest infective and multibacillary form of leprosy. Clinical manifestations are consequent to the haematogenous spread of bacilli and include macules, plaques and nodules in a symmetric distribution or a diffuse infiltration of the skin. LL may mimic many different inflammatory and neoplastic skin diseases and in a small percentage of patients, skin manifestation may be atypical. This article reports the case of a South American child with LL presenting with symmetrically distributed hypopigmented macules previously misdiagnosed as pytiriasis alba, atopic dermatitis and pityriasis versicolor. Atopy and pityriasis versicolor are common skin conditions that can be also observed in leprosy patients and that can masquerade the diagnosis of LL, especially if occurring in dark skin. Dermatologists in Europe should be aware of this unusual form of presentation of leprosy and must take in mind Hansen disease in the differential diagnosis in patients coming from endemic areas.

    Full Text Available Leprosy is an ancient deforming disease caused by Mycobacterium leprae, which is still poorly understood and often feared by the general public and even by some in the health care professions Fortunately, the outlook for patients has dramatically improved over the last three decades with the introduction of multi-drug treatment and management strategies that have somewhat diminished the stigma of this diagnosis. We report a rare case of leprosy of larynx. A 45 year old man presented with complaints cough, dyspnea and hoarseness since many years ago. Because of demonstration of acid fast bacilli in smear of his sputum, the diagnosis of tuberculosis was made and anti tuberculosis treatment was initiated. But he developed fever and his symptoms exacerbated. In examination there was a tender erythematous nodule on right supraclavicular region, loss of eyebrows and lashes and disseminated hyper and hypo pigmented cutaneous lesions on abdomen, thorax, back with normal chest x ray. Laryngoscopy to rule out laryngeal tuberculosis was done and granulomatous lesion was seen. Laryngeal and skin biopsy was performed which numerous acid fast bacilli, macrophages and foamy cells suggestive of lepromatous leprosy were demonstrated in both specimens. Treatment was started on multi bacillary regime of WHO multidrug therapy. In conclusion, this report highlights the importance of systemic involvement in lepromatous leprosy especially when the initial presentation is laryngitis or respiratory symptoms. Laryngeal leprosy may mistaken with tuberculosis laryngitis due to respiratory problems and existence of acid fast bacilli in respiratory secretions.

    Demonstration of lepra bacilli is essential for definite or unequivocal diagnosis of pure neuritic leprosy (PNL) on nerve biopsy. However, nerves always do not show bacilli owing to the changes of previous therapy or due to low bacillary load in tuberculoid forms. In absence of granuloma or lepra bacilli, other morphologic changes in endoneurium and perineurium can be of help in making a probable diagnosis of PNL and treating the patient with multidrug therapy. Forty-six biopsies of PNL were retrospectively reviewed and histologic findings were compared with 25 biopsies of non leprosy neuropathies (NLN) including vasculitic neuropathy and chronic inflammatory demyelinating polyneuropathy (CIDP). The distribution of endoneurial infiltrate and fibrosis, perineurial thickening, and myelin abnormalities were compared between PNL and NLN biopsies and analyzed by Chi-square test. Out of 46 PNL casses, 24 (52.17 %) biopsies were negative for acid fast bacilli (AFB). In these cases, the features which favor a diagnosis of AFB-negative PNL were endoneurial infiltrate (51.1%), endoneurial fibrosis (54.2%), perineurial thickening (70.8%), and reduced number of myelinated nerve fibers (75%). Nerve biopsy is an efficient tool to diagnose PNL and differentiate it from other causes of NLN. In absence of AFB, the diagnosis of PNL is challenging. In this article, we have satisfactorily evaluated the various hisopthological features and found that endoneurial inflammation, dense fibrosis, and reduction in the number of myelinated nerve fibers are strong supportive indicators of PNL regardless of AFB positivity.

    Thirty lepromatous and Borderline lepromatous leprosy patients were treated with multidrug therapy in an open trial. Fifteen of them received the standard WHO multidrug regimen ie., rifampicin 600 mg and clofazimine 300 mg monthly, supervised, and dapsone 100 mg daily and clofazimine 100 mg on alternate days as self administered; the other 15 received a modified multidrug therapy regimen comprising of rifampicin 600 mg, clofazimine 100 mg and dapsone 100 mg daily for 21 days as suggested by the Indian Association of Leprologists, followed by the standard WHO regimen. The observation period was six months. Clinical, bacteriological, histological and immunological parameters were studied. The fall in morphological index was much faster in patients receiving modified multidrug therapy regimen compared to those receiving the standard WHO regimen. Otherwise, there was no difference between the two groups of patients. Five patients developed type I (upgrading) reaction with one developing ulnar nerve paralysis. No untoward effects of drugs were noted in the study subjects except for darkening of skin colour of all the patients.

    Full Text Available Background: Combating Mycobacterium leprae is known to be via T-helper1 response. However, other T-helper effector cells; T-helper17 and T-helper2; play a role, particularly in the context of disease type. Aims: We aimed to evaluate serum levels of interleukin (IL-17 (T-helper17 cytokine and IL-4 (T-helper2 cytokine in untreated patients with different types of leprosy, compared to controls. Methods: Using enzyme-linked immunosorbent assay, serum IL-17 and IL-4 levels were estimated in 43 leprotic patients and 43 controls. Patients were divided into six groups; tuberculoid, borderline cases, lepromatous, erythema nodosum leprosum (ENL, type 1 reactional leprosy, and pure neural leprosy. Patients were also categorized according to bacillary load and the presence or absence of reactions. Results: Serum IL-17 was significantly lower in cases (4-61.5 pg/mL; median 19, compared to controls (26-55 pg/mL; median 36 (P < 0.001, and was significantly lower in each type of leprosy compared to controls, with the lowest level in lepromatous leprosy (4-61.5 pg/mL; median 12.5. Significantly elevated serum IL-4 was found in patients (1.31-122.4 pg/mL; median 2.31 compared to controls (1.45-5.72 pg/mL; median 2.02 (P = 0.008, with the highest level among lepromatous leprosy patients (2-87.2 pg/mL; median 28.9, and the lowest in type 1 reactional leprosy (1.4-2.5 pg/mL; median 1.87 (P = 0.006. Conclusion: Defective secretion of IL-17 is related to disease acquisition as well as progression toward lepromatous pole in leprosy patients. The overproduction of IL-4 in patients with lepromatous leprosy may infer their liability to develop ENL. Nevertheless, the small number of the studied population is a limitation.

    Full Text Available Leprosy neuropathy is characterized by initial involvement of the small nerve fibers, later followed by involvement of the large fibers, when routine nerve conduction studies become abnormal. To increase the diagnostic yield and precocity of these studies, we applied the near nerve technique to the sural nerve of 8 leprosy patients. Contrary to our expectations, the main component of the sural nerve sensory action potential was abnormal in all patients, but the minimum conduction velocity originating from small 3-6 mm fibers was normal or only mildly involved in three patients. Also, although Schwann cells are the first to be involved in leprosy, the results are suggestive of axonal degeneration instead of demyelination. To better understand the neurophysiology and physiology of leprosy and to increase the accuracy and precocity of the diagnosis, it will be necessary to investigate patients in the very early stages of the disease and to correlate these findings with the corresponding nerve pathology.Na hanseníase, as fibras de pequeno calibre são acometidas antes que as fibras mais grossas, ocasião em que o estudo da condução torna-se anormal. Neste estudo, utilizou-se a técnica de registro com eletrodos justa-nervo com a finalidade de aumentar a precocidade e a acurácia diagnóstica, devido à sua capacidade de detectar potenciais oriundos de fibras com cerca de 3-6 mm. Contrário às nossas expectativas, o componente principal do potencial sensitivo do nervo sural foi anormal em todos os pacientes, enquanto a velocidade de condução mínima foi normal ou discretamente alterada em 3 pacientes. Além disso, os resultados são sugestivos de degeneração axonal e não mielinopatia, como seria esperado em uma doença que compromete inicialmente a bainha de mielina. Para um melhor entendimento da fisiologia e fisiopatologia, e para aumentar a precocidade diagnóstica, é fundamental estudar casos bem precoces e correlacionar os dados

    2013-01-01

    Full Text Available Background: The diagnosis of pure neural leprosy (PNL remained subjective because of over-dependence of clinical expertise and a lack of simple yet reliable diagnostic tool. The criteria for diagnosis, proposed by Jardim et al., are not routinely done by clinicians in developing country as it involves invasive nerve biopsy and sophisticated anti-PGL-1 detection. We conducted a study using fine needle aspiration cytology (FNAC coupled with Ziehl Neelsen staining (ZN staining and Multiplex- Polymerase Chain Reaction (PCR specific for M. leprae for an objective diagnosis of pure neural leprosy (PNL, which may be simpler and yet reliable. Aim: The aim of the study is to couple FNAC with ZN staining and multiplex PCR to diagnose pure neural leprosy patients rapidly, in simpler and yet reliable way. Methods: Thirteen patients of PNL as diagnosed by two independent consultants were included as case, and 5 patients other than PNL were taken as control in the study. Fine needle aspiration was done on the affected nerve, and aspirates were evaluated for cytology, ZN staining and multiplex- PCR. Results: Out of the 13 cases where fine needle aspiration was done, M. leprae could be elicited in the nerve tissue aspirates in 5 cases (38.4% with the help of conventional acid-fast staining and 11 cases (84.6% with the help of multiplex PCR. On cytological examination of the aspirates, only 3 (23% cases showed specific epithelioid cells, whereas 8 (61.5% cases showed non-specific inflammation, and 2 (15.3% cases had no inflammatory cells. Conclusion: Our study demonstrates that in the field of laboratory diagnosis of PNL cases, FNAC in combination with ZN staining for acid-fast bacilli (AFB and Multiplex-PCR can provide a rapid and definitive diagnosis for the majority of PNL cases. FNAC is a less-invasive, outdoor-based and simpler technique than invasive nerve biopsy procedure. Thus, this study may enlighten the future path for easy and reliable diagnosis of

    Full Text Available Skin and nerve biopsies were done in 33 cases of different clinical types of leprosy selected from Dermatology OPD of Medical College and Hospitals, Calcutta during 1994-95. Histopathological results were compared with emphasis on the role of nerve biopsies in detection of patients with multibacillary leprosy. The evident possibility of having patients with multibacillary leprosy in peripheral leprosy with multiple drugs. It is found that skin and nerve biopsy are equally informative in borderline and lepromatour leprosy and is the only means to diagnose polyneuritic leprosy. Nerve biopsy appears to be more informative in the diagnosis of all clinical types of leprosy.

    Full Text Available Leprosy in pregnancy is a rarely encountered event. Out of the 2000 patients detected of leprosy annually, two to three are pregnant women and majority of them are diagnosed in the third trimester. We, hereby, report a case of borderline tuberculoid leprosy with Type I lepromatous reaction in a 26-year-old pregnant woman in early second trimester with a large raised red coloured lesion over the forehead and six other small lesions involving the trunk and limbs with reduced sensory perception over involved skin. Occurrence of leprosy in an obstetric patient belonging to low prevalence area of India is infrequent especially in the post elimination era. However, we do need to have a high index of suspicion in lesions suggestive of the disease.

    Lucio's phenomenon (LPh) is considered a necrotizing panvasculitis and a variant of leprosy Type 2 reaction, clinically characterised by necrotic-haemorrhagic lesions on the extremities and trunk. LPh is observed in diffuse lepromatous leprosy (DLL or Lucio-Latapí leprosy). This is a distinct form of lepromatous leprosy (LL) reported mainly in Mexico. Anti-phospholipid antibody syndrome (APS) has been rarely described in LPh. We report a case of Lucio-Latapí leprosy with LPh observed in a patient from the province of El Oro in Ecuador, who presented clinical manifestations of long standing DLL (non-nodular infiltration of the skin, collapse of the nasal pyramid, madarosis, atrophy of the earlobes), of LPh (necrotic-haemorrhagic macules with irregular shapes) and of APS (necrosis of the right big and second toe). Histopathology showed perineural and periadnexal foamy macrophages with numerous bacilli (diagnostic of LL) in the subcutis, a mild lobular panniculitis with a large subcutaneous vessel infiltrated by macrophages in the wall (typical of LPh) and vessels of the superficial and mid dermis occluded by thrombi but without signs of vasculitis (typical of occlusive vasculopathy as in APS). Our observations suggest that some cases of LPh may be associated with APS. Anti-cardiolipin antibodies (aCL) and lupus anticoagulant (LA) should be tested in patients with LPh because this may have therapeutic implications.

    Summary Background Mycobacterium leprae was the only known cause of leprosy until 2008, when a new species, named Mycobacterium lepromatosis, was found to cause diffuse lepromatous leprosy (DLL), a unique form of leprosy endemic in Mexico. Methods We sought to differentiate the leprosy agents among 120 Mexican patients with various clinical forms of leprosy and to compare their relative prevalence and disease features. Archived skin biopsy specimens from these patients were tested for both M. leprae and M. lepromatosis using polymerase chain reaction-based species-specific assays. Results Eighty-seven (72.5%) patients were confirmed for etiologic species, including 55 with M. lepromatosis, 18 with M. leprae, and 14 with both organisms. The endemic regions of each agent differed but overlapped. Patients with M. lepromatosis were younger and from more states, and their clinical diagnoses included 13 DLL, 34 lepromatous leprosy (LL), and eight other forms of leprosy. By contrast, the diagnoses of patients with M. leprae included none DLL, 15 LL and three other forms. Thus, M. lepromatosis caused DLL specifically (p=0.023). Patients with M. lepromatosis also showed more variable skin lesions and the extremities were the commonest biopsy sites. Finally, patients with dual infections manifested all clinical forms and accounted for 16.1% of all species-confirmed cases. Conclusions M. lepromatosis is another cause of leprosy and is probably more prevalent than M. leprae in Mexico. It mainly causes LL and also specifically DLL. Dual infections caused by both species may occur in endemic area. PMID:22788812

    Full Text Available This study sought to verify the correlation between leprosy types and the adverse effects of treatment drugs. This quantitative, prospective, nested study was developed at the Dona Libânia Dermatology Centre in Fortaleza, Brazil. Data were collected from November 2007-November 2008. During this period, 818 leprosy patients were diagnosed and began treatment. Forty patients with tuberculoid leprosy (TT were selected. Twenty patients followed a standard therapy of dapsone and rifampicin and 20 were administered dapsone, rifampicin and clofazimine (U-MDT. Twenty patients with borderline lepromatous (BL and lepromatous leprosy (LL were also selected and treated with U-MDT. All of the subjects received six doses. With the exception of haemolytic anaemia, there was a low incidence of adverse effects in all the groups. We did not observe any differences in the incidence of haemolytic anaemia or other side effects across groups of patients with TT, BL or LL treated with U-MDT.

    Full Text Available Pure neuritic leprosy has always been an enigma due to its clinical and management ambiguities. Although only the Indian Association of Leprologist's classification recognizes 'pure neuritic leprosy' as a distinct sub group of leprosy, cases nonetheless are reported from various countries of Asia, Africa, South America and Europe, indicating its global relevance. It is important to maintain pure neuritic leprosy as a subgroup as it constitutes a good percentage of leprosy cases reported from India, which contributes to more than half of global leprosy numbers. Unfortunately, a high proportion of these patients present with Grade 2 disability at the time of initial reporting itself due to the early nerve involvement. Although skin lesions are absent by definition, when skin biopsies were performed from the skin along the distribution of the affected nerve, a proportion of patients demonstrated leprosy pathology, revealing sub-clinical skin involvement. In addition on follow-up, skin lesions are noted to develop in up to 20% of pure neuritic leprosy cases, indicating its progression to manifest cutaneous disease. Over the decades, the confirmation of diagnosis of pure neuritic leprosy has been subjective, however, with the arrival and use of high-resolution ultrasonography (HRUS for nerve imaging, we have a tool not only to objectively measure and record the nerve thickening but also to assess the morphological alterations in the nerve including echo texture, fascicular pattern and vascularity. Management of pure neuritic leprosy requires multidrug therapy along with appropriate dose of systemic corticosteroids, for both acute and silent neuritis. Measures for pain relief, self-care of limbs and physiotherapy are important to prevent as well as manage disabilities in this group of patients.

    Full Text Available Dada la frecuencia con que la lepra afecta al sistema nervioso, consideramos de interés realizar un estudio electromiográfico en zonas corporales clínicamente sanas. Hemos elegido para tal fin 14 enfermos que no tenían lesión sensitivo-motora clínicamente perceptible en el nervio cubital izquierdo. Hemos estudiado tambén un grupo de control de 5 enfermos con lesión evidente del mismo nervio. Se ha comprobado que de los 14 enfermos que aparentemente no tenían lesión del nervio cubital izquierdo, en 12 de ellos surgieron alteraciones electromiográficas que señalan la lesión del nervio, aunque en um grado menor que en el grupo de control. Este hecho nos hace pensar que la agresión que sufre el sistema nervioso periférico es de una extensión mayor que lo hace suponer la clínica, o que las lesiones anatómicas no retrogradan como nos lo sugiere el examen de los pacientes.Considering the frequency of the peripheral nervous system envolvement in leprosy 14 patients without clinical signs indicating impairment of the left ulnar nerve were submitted to electromyographic studies. All were chronic cases in which the disease had an evolution of three years for the most recent one, the longest during thirty one years. All patients were under leprosy treatment: nine had lepromatous leprosy, four had tuberculoid form, one had a dimorfous form. At the same time, as a control group, were studied 5 patients presenting clinical signis of injury of the left ulnar nerve. An electromiograph DISA with 3 channels, a Multistin estimulator and concentric electrodes were employed. In all the 19 cases the espontaneous activity, the type of recruiting reaction and the conduction velocity were analysed. Results were synthetized in Tables 1 and 2. The finding of electromyographic abnormalities in clinically healthy territores of 12/14 patients examined lead to the conclusion that in leprosy the agression to the peripheral nervous system is more extensive than

    Full Text Available This is a case report of 22-year-old man who was suffering from epididymo-orchitis for more than 2 years. Several months after the onset of the condition, the patient developed bilateral upper-limb and lower-limb numbness and tingling sensation with hypothesia, which was further complicated by nonhealing foot ulcer, arthralgia, and generalized maculopapular skin rash. The patient was initially managed as rheumatoid arthritis associated with vasculitis, which was later diagnosed as lepromatous leprosy. Musculoskeletal complaints are not exclusive to only autoimmune diseases; it can also be observed in several disorders, such as infectious diseases. It is challenging for any physician to properly diagnose patients with leprosy as differentiating leprosy from other systemic rheumatic disease is pivotal.

    Full Text Available A cross-sectional clinical trial in which the serum anti-phenolic glycolipid (anti-PGL-1 antibodies were analysed in household contacts (HHC of patients with leprosy as an adjunct early leprosy diagnostic marker was conducted. The families of 83 patients underwent clinical examination and serum anti-PGL1 measurement using enzyme-linked immunosorbent assay. Of 320 HHC, 98 were contacts of lepromatous leprosy (LL, 80 were contacts of borderline lepromatous (BL, 28 were contacts of borderline (BB leprosy, 54 were contacts of borderline tuberculoid (BT, 40 were contacts of tuberculoid (TT and 20 were contacts of indeterminate (I leprosy. Consanguinity with the patients was determined for 232 (72.5% HHC. Of those 232 contacts, 183 had linear consanguinity. Forty-nine HHC had collateral consanguinity. Fifty-eight contacts (18.1% tested positive for anti-PGL1 antibodies. The number of seropositive contacts based on the clinical forms of the index case was 17 (29.3% for LL, 15 (25.9% for BL, one (1.7% for BB, 14 (24.1% for BT, three (5.2% for TT and eight (13.7% for I. At the one year follow-up, two (3.4% of these seropositive contacts had developed BT leprosy. The results of the present study indicate that the serum anti-PGL-1 IgM antibody may be useful for evaluating antigen exposure and as a tool for an early leprosy diagnosis in HHC.

  2. Genetics of leprosy reactions: an overview

    Full Text Available Type-1 (T1R and Type-2 (T2R leprosy reactions (LR, which affect up to 50% of leprosy patients, are aggressive inflammatory episodes of sudden onset and highly variable incidence across populations. LR are often diagnosed concurrently with leprosy, but more frequently occur several months after treatment onset. It is not uncommon for leprosy patients to develop recurring reactional episodes; however, they rarely undergo both types of LR. Today, LR are the main cause of permanent disabilities associated with leprosy and represent a major challenge in the clinical management of leprosy patients. Although progress has been made in understanding the immunopathology of LR, the factors that cause a leprosy patient to suffer from LR are largely unknown. Given the impact that ethnic background has on the risk of developing LR, host genetic factors have long been suspected of contributing to LR. Indeed, polymorphisms in seven genes [Toll-like receptors (TLR1, TLR2, nucleotide-binding oligomerisation domain containing 2, vitamin D receptor, natural resistance-associated macrophage protein 1, C4B and interleukin-6] have been found to be associated with one or more LR outcomes. The identification of host genetic markers with predictive value for LR would have a major impact on nerve damage control in leprosy. In this review, we present the recent advances achieved through genetic studies of LR.

    Full Text Available BACKGROUND: Patients with localized tuberculoid and generalized lepromatous leprosy show respectively Th1 and Th2 cytokine profile. Additionally, other patients in both types of leprosy also show a non discriminating Th0 cytokine profile with both interferon-γ and IL-4. The present study investigated the role of Th17 cells which appear to be a distinct subtype of Th subtypes in 19 tuberculoid and 18 lepromatous leprosy patients. Five healthy subjects with long term exposure to infection and 4 skin biopsies from healthy subjects undergoing cosmetic surgery were used as controls. METHODOLOGY/PRINCIPLE FINDINGS: An array of Th17 related primers for cytokines, chemokines and transcription factors was used in real time reverse transcribed PCR to evaluate gene expression, ELISA for cytokine secretion in the supernatants of antigen stimulated PBMC cultures and flow cytometry for establishing the phenotype of the IL-17, IL-21 producing cells. CONCLUSIONS/SIGNIFICANCE: IL-17 isoforms showed significantly higher expression and release in supernatants of antigen stimulated PBMC cultures and dermal lesions of healthy contacts and tuberculoid leprosy as compared to lepromatous leprosy (p<0.003. This was further confirmed by Th17 associated transcription factor RORC, cytokines IL-21, IL-22, and IL-23, chemokines MMP13, CCL20, CCL22. Of interest was the association of IL-23R and not IL-6R with IL-17(+ cells. The Th17 cells were CD4(+ CCR6(+ confirming their effector cell lineage. Polarized Th1 cytokines were seen in 3/7 tuberculoid and Th2 cytokines in 5/10 lepromatous leprosy patients. Of importance was the higher association of Th17 pathway factors with the non-polarized Th0 types as compared to the polarized Th1 and Th2 (p<0.01. Our study draws attention to a third type of effector Th cell that may play a role in leprosy.

    Non-healing chronic trophic ulceration is very common in leprosy patients. Marjolin's ulcer consists of the malignant transformation of a chronic ulcerative lesion. Nodular melanoma developing from Marjolin's ulcer, caused by a trophic ulceration of a leprosy patient, is very rare with only a few cases reported in the literature. Due to the disguised presentation of these malignancies within trophic ulceration lesions in leprosy, neoplastic transformation is frequently overlooked, leading to misdiagnosed and delayed treatment. This paper reports a case of an 83-year-old man with lepromatous leprosy and chronic ulceration on the foot for 22 years. Over a period of 2 months, the ulcer enlarged, turned black, and became more painful. The patient underwent regional excision and immunotherapy after the diagnosis of malignant nodular melanoma. After 9 months follow-up, no metastasis was found. There were no external sources of funding for this study. The authors have no conflicts of interest to declare.

    To evaluate musculoskeletal involvement and autoantibodies in pediatric leprosy patients. 50 leprosy patients and 47 healthy children and adolescents were assessed according to musculoskeletal manifestations (arthralgia, arthritis, and myalgia), musculoskeletal pain syndromes (juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome, and tendinitis), and a panel of autoantibodies and cryoglobulins. Health assessment scores and treatment were performed in leprosy patients. At least one musculoskeletal manifestation was observed in 14% of leprosy patients and in none of the controls. Five leprosy patients had asymmetric polyarthritis of small hands joints. Nerve function impairment was observed in 22% of leprosy patients, type 1 leprosy reaction in 18%, and silent neuropathy in 16%. None of the patients and controls presented musculoskeletal pain syndromes, and the frequencies of all antibodies and cyoglobulins were similar in both groups (p > 0.05). Further analysis of leprosy patients demonstrated that the frequencies of nerve function impairment, type 1 leprosy reaction, and silent neuropathy were significantly observed in patients with versus without musculoskeletal manifestations (p = 0.0036, p = 0.0001, and p = 0.309, respectively), as well as multibacillary subtypes in leprosy (86% vs. 42%, p = 0.045). The median of physicians' visual analog scale (VAS), patients' VAS, pain VAS, and Childhood Health Assessment Questionnaire (CHAQ) were significantly higher in leprosy patients with musculoskeletal manifestations (p = 0.0001, p = 0.002, p = 0002, and p = 0.001, respectively). This was the first study to identify musculoskeletal manifestations associated with nerve dysfunction in pediatric leprosy patients. Hansen's disease should be included in the differential diagnosis of asymmetric arthritis, especially in endemic regions. Copyright © 2014 Sociedade Brasileira de Pediatria.

    Leprosy, or Hansen's disease, is a chronic infectious disease caused by the bacillus Mycobacterium leprae. In 2000, the World Health Organization (WHO) defined the elimination of the disease as a global prevalence of less than one case per 10,000 population. However, disease transmission is an ongoing worldwide public health concern, as evidenced by the more than 220,000 new cases diagnosed each year. This study is an update of the incidence and prevalence of leprosy in Puerto Rico for the period of 2000-2014. A retrospective analysis of data was obtained from the Tropical Disease Clinic (TDC) of the University of Puerto Rico School of Medicine. Sixty-three new cases of leprosy are detailed in this study. Disease incidence and prevalence were 1.65 and 5.26 per 100,000 inhabitants (of the island of Puerto Rico), respectively, and an average of 4.2 new cases per year. Most of the male patients in the study suffered from lepromatous leprosy (P = 0.026). In all, 47 (74.6%) patients had been born in Puerto Rico, and 29 (46%) had an affected family member or were in close contact with someone with leprosy. Compared to those of previous studies, these results demonstrate a decrease in both the incidence and prevalence of leprosy in Puerto Rico over the past 15 years. The relatively high prevalence of leprosy in Puerto Rico means that it remains endemic on the island. Concerted efforts must be undertaken to achieve the goal of the elimination of this old and stigmatized disease. © 2017 The International Society of Dermatology.

    Full Text Available Erythema nodosum leprosum (ENL is a common immune-mediated complication of lepromatous (LL and borderline lepromatous (BL leprosy. Most patients experience chronic or multiple acute ENL over many years during an economically active period of their lives. Understanding the economic burden of ENL is essential to provide effective patient support, yet this area has not been investigated.Ninety-one patients with LL or BL leprosy attending a leprosy hospital in Purulia district of West Bengal, India, were interviewed using a structured questionnaire. Cases (n = 53 were identified as those who had one or more episodes of ENL within the last 3 years. Controls (n = 38 had LL or BL leprosy but no history of ENL. Data were collected on household income, direct and indirect costs, and coping strategies.The total household cost was Rs 1543 per month or 27.9% (IQR 13.2-52.6 of monthly household income for cases, and Rs 237 per month or 4.9% (IQR 1.7-13.4 of monthly household income for controls. Indirect costs accounted for 65% of total household costs for cases. Direct costs accounted for the remaining 35% of household costs, and resulted almost entirely from treatment-seeking in the private sector. Total household costs exceeded 40% of household income for 37.7% of cases (n = 20 and 2.6% of controls (n = 1 [1 USD = 59 INR].Households affected by ENL face significant economic burden and are at risk of being pushed further into poverty. Health policy should acknowledge the importance of private sector provision and the significant contribution to total household costs of lost productivity (indirect cost. Further work is needed to explore this area and identify solutions.

    Multibacillary leprosy may involve the oral mucosa, with or without apparent lesions. There are few studies that deal with this issue in the era of multidrug therapy. To assess the frequency of oral mucosa involvement in multibacillary leprosy patients. A transversal study with twenty non-treated multibacillary leprosy patients. The patients were treated in Dracena, São Paulo, between 2000 and 2002. Clinical examination of the oral mucosa was carried out. All patients were submitted to jugal mucosa, soft palate and tongue biopsies, in altered or in pre-established sites. The cross-sections were stained by techniques of hematoxilin-eosin and Ziehl-Neelsen. Granuloma and alcohol-acid-resistant bacilli findings determined the specific histopathological involvement. The study involved 19 patients with an average of 2.5 years of disease progression. Specific histopathological involvement occurred in the tongue and soft palate of one lepromatous patient with an apparently normal oral mucosa. (1) Clinical alterations in the oral mucosa does not imply disease involvement, it is necessary to have histopathological confirmation. (2) Apparent specific clinical alterations are rare. (3) The clinically normal oral mucosa can show specific histopathological involvement.

    For many years, the biblical term tzaraat has referred to leprosy. In fact, the disease or diseases described under this name have no relationship to leprosy, as it was known in the Middle Ages or today; moreover, the term referred not only to skin disease, but also to the state of the ritual impurity and punishment for the sins. Although the real nature of tzaraat remains unknown, the differential diagnosis might include the following: Psoriasis, seborrheic dermatitis, favus, dermatophyte infections, nummular dermatitis, atopic dermatitis, pityriasis rosea, crusted scabies, syphilis, impetigo, sycosis barbae, alopecia areata, furuncles, scabies, neurodermatitis, scarlet fever, lupus erythematosus, lichen sclerosus et atrophicus, folliculitis decalvans, morphea, sarcoidosis, and lichen planopilaris. Leprosy became interchangeable with the biblical leprosy due to two inaccurate translations: The Hebrew tzaraat was first translated into Greek as leprosy in the sixth century, and later, the word leprosy was translated into Arabic as lepra in the ninth century.

    Full Text Available Introduction. Damage of testicles is frequent in lepromatous leprosy worsen by the presence of erythema nodosum leprosum.
    Objective. One patient is presented who developed lepromatous leprosy and erythema nodosum leprosum with important testicular compromise.
    Material and methods. A 28 year old man patient who had lepromatous leprosy since his 22 was studied. During a polychemotherapy treatment for the lepromatous leprosy, he presented chronic erythema nodosum leprosum that affected both testicles and did not respond to the conventional treatment. A left orchidectomy was practiced to treat the persistent pain.
    Results. The extracted testis evidenced the following findings: tubular atrophy, remarkable fibrosis, cumulus of foamy macrophages without rods, focal Leydig cell hyperplasia, linfocitary and granulomatous arteritis and endarteritis of small and medium size vessels. These changes were also observed in the epididymis. Two years after the polychemoterapy and the orchidectomy, the patient revealed azoospermy, normal total testosterone, discretely diminished free testosterone and elevated luteinizing hormone and follicle-stimulating hormone. No loss of libido or sexual activity. We reviewed general concepts about erythema nodosum leprosum and the pathologic changes produced by leprosy in the testis.
    Conclusion. Lepromatous leprosy may lead to hypogonadism. This should be considered by the leprosy programs in order to avoid and treat the consequences of the possible hypogonadism.

    Full Text Available INTRODUCTION: This study was developed to evaluate the situation of leprosy in the general population of the municipality of Buriticupu, State of Maranhão, Brazil. METHODS: We used the method of active search to identify new cases from 2008 to 2010. Bacilloscopy of intradermal scrapings was performed in all patients with skin lesions compatible with leprosy, and histopathological examination in those who had doubts on the definition of the clinical form. RESULTS: The study included 19,104 individuals, with 42 patients diagnosed with leprosy after clinical examination, representing a detection rate of 219.84 per 100,000 inhabitants. The predominant clinical presentation was tuberculoid with 24 (57.1% cases, followed by borderline with 11, indeterminate with four, and lepromatous with three cases. The study also allowed the identification of 81 patients with a history of leprosy and other skin diseases, such as pityriasis versicolor, dermatophytosis, scabies, vitiligo, and skin carcinoma. The binomial test showed that the proportion of cases in the headquarters was significantly higher than that in the villages (p = 0.04, and the generalized exact test showed that there was no association between age and clinical form (p = 0.438 and between age and gender (p = 0.083. CONCLUSIONS: The elevated detection rate defines the city as hyperendemic for leprosy; the active search for cases, as well as the organization of health services, is an important method for disease control.

    Full Text Available We report a case of misdiagnosed leprosy in a 21-year-old Malagasy male, who, improperly treated, developed secondary mycobacterial resistance to fluoroquinolone. The patient contracted the infection 9 years prior to the current consultation, displaying on the right thigh a single papulonodular lesion, which progressively spread to the lower leg, back, and face. Initial administration of ciprofloxacin and prednisolone led to temporary and fluctuating improvement. Subsequent long-term self-medication with ciprofloxacin and corticosteroid did not heal the foul and nonhealing ulcers on the legs and under the right sole. Histopathological findings were compatible with lepromatous leprosy. Skin biopsy was positive for acid-fast bacilli and PCR assay confirmed the presence of a fluoroquinolone-resistant strain of Mycobacterium leprae (gyrA A91V. After 6 months of standard regimen with rifampicin, clofazimine, and dapsone, clinical outcome significantly improved. Clinical characteristics and possible epidemiological implications are discussed.

    Full Text Available Leprosy (Hansen’s disease is a chronic granulomatous bacterial infection mainly affecting the skin and peripheral nervous system yet also involving other organs and systems as a result of a pathological process. The causative agent of leprosy - Mycobacterium leprae - is an obligate intracellular microorganism. Despite the removal of a threat of a leprosy epidemic, European countries still record outbreaks of the disease mainly among migrants coming from endemic areas. A golden standard of the treatment of leprosy is a WHO-recommended combined drug therapy comprising drugs such as dapsone, clofazimine and rifampicin. The article provides current data on the mechanisms of action, efficacy and safety of these drugs and their combined scheme of treatment obtained as a result of clinical trials. Moreover, it also reviews new regimens of the drug therapy of leprosy including those with the use of drugs from the group of fluoroquinols as well as immunotherapy of the disease.

    Full Text Available Bombay Leprosy Project has conducted operational research into cost effective ways of using therapeutic management for prevention of disabilities (POD. The goal of achieving this are broadly divided as 1 prevention of impairments and disabilities [POID] and 2 prevention of worsening of disabilities [POWD]. About 33-56% of newly registered leprosy patients already have clinically detectable nerve function impairment [NFI], often no longer amenable to MDT. An analysis of 892 leprosy cases treated with WHO-MDT stresses the need to focus attention on leprosy patients having > 5 skin lesions and multiple nerve thickening. Assessment of 454 disabled leprosy patients after 4 years indicated that the compliance for the services offered was good and it helped to improve the disability status in more than 50% of patients. In terms of effectiveness of the services, it was found to be effective in preventing worsening of deformities in hands and healing of trophic ulcers in feet. The methodology adopted has also helped us to develop an operational research model about the necessity to systematize the assistance and support to be given if the services can be routed through a public health facility. Because of the large numbers of leprosy patients with disability living in this region and the limited resources available, the services have to be targeted towards those who are most in need. The major advantage of such community based program is an attempt to eliminate the social stigma in the patients′ families and the education of the community.

    Leprosy is caused by Mycobacterium leprae and manifests as damage to the skin and peripheral nerves. The disease is dreaded because it causes deformities, blindness and disfigurement. Worldwide, 2 million people are estimated to be disabled by leprosy. Multidrug therapy is highly effective in curing leprosy, but treating the nerve damage is much more difficult. The World Health Assembly targeted to eliminate leprosy as a public health problem from the world by 2000. The objective of the review was to assess the successes of the leprosy elimination strategy, elimination hurdles and the way forward for leprosy eradication. A structured search was used to identify publications on the elimination strategy. The keywords used were leprosy, elimination and 2000. To identify potential publications, we included papers on leprosy elimination monitoring, special action projects for the elimination of leprosy, modified leprosy elimination campaigns, and the Global Alliance to eliminate leprosy from the following principal data bases: Cochrane data base of systematic reviews, PubMed, Medline, EMBASE, and the Leprosy data base. We also scanned reference lists for important citations. Key leprosy journals including WHO publications were also reviewed. The search identified 63 journal publications on leprosy-related terms that included a form of elimination of which 19 comprehensively tackled the keywords including a book on leprosy elimination. In 1991, the 44th World Health Assembly called for the elimination of leprosy as a public health problem in the world by 2000. Elimination was defined as less than one case of leprosy per 10000-population. Elimination has been made possible by a confluence of several orders of opportunities: the scientific (the natural history of leprosy at the present state of knowledge), technological (multi-drug therapy and the blister pack); political (commitment of governments) and financial (support from NGOs for example the Nippon Foundation that

    Full Text Available Leprosy, a chronic infectious disease caused by Mycobacterium leprae, is a major public health problem in poor and developing countries of the Americas, Africa, and Asia. MicroRNAs (miRNAs, which are small non-coding RNAs (18–24 nucleotides, play an important role in regulating cell and tissue homeostasis through translational downregulation of messenger RNAs (mRNAs. Deregulation of miRNA expression is important for the pathogenesis of various neoplastic and non-neoplastic diseases and has been the focus of many publications; however, studies on the expression of miRNAs in leprosy are rare. Herein, an extensive evaluation of differentially expressed miRNAs was performed on leprosy skin lesions using microarrays. Leprosy patients, classified according to Ridley and Jopling’s classification or reactional states (R1 and R2, and healthy controls (HCs were included. Punch biopsies were collected from the borders of leprosy lesions (10 tuberculoid, 10 borderline tuberculoid, 10 borderline borderline, 10 borderline lepromatous, 4 lepromatous, 14 R1, and 9 R2 and from 9 HCs. miRNA expression profiles were obtained using the Agilent Microarray platform with miRBase, which consists of 1,368 Homo sapiens (hsa-miRNA candidates. TaqMan quantitative real-time reverse transcription polymerase chain reaction (RT-PCR was used to validate differentially expressed miRNAs. Sixty-four differentially expressed miRNAs, including 50 upregulated and 14 downregulated (fold change ≥2.0, p-value ≤ 0.05 were identified after comparing samples from patients to those of controls. Twenty differentially expressed miRNAs were identified exclusively in the reactional samples (14 type 1 and 6 type 2. Eight miRNAs were validated by RT-PCR, including seven upregulated (hsa-miR-142-3p, hsa-miR-142-5p, hsa-miR-146b-5p, hsa-miR-342-3p, hsa-miR-361-3p, hsa-miR-3653, and hsa-miR-484 and one downregulated (hsa-miR-1290. These miRNAs were differentially expressed in leprosy and

    Leprosy is a chronic granulomatous disease caused by the bacillus Mycobacterium leprae. It primarily affects the skin and peripheral nerves and is still endemic in various regions of the world. Clinical presentation depends on the patient's immune status at the time of infection and during the course of the disease. Leprosy is associated with disability and marginalization. Diagnosis is clinical and is made when the patient has at least 1 of the following cardinal signs specified by the World Health Organization: hypopigmented or erythematous macules with sensory loss; thickened peripheral nerves; or positive acid-fast skin smear or skin biopsy with loss of adnexa at affected sites. Leprosy is treated with a multidrug combination of rifampicin, clofazimine, and dapsone. Two main regimens are used depending on whether the patient has paucibacillary or multibacillary disease.

    2018-03-01

    Full Text Available Leprosy remains as a public health problem and its physiopathology is still not fully understood. MicroRNAs (miRNA are small RNA non-coding that can interfere with mRNA to regulate gene expression. A few studies using DNA chip microarrays have explored the expression of miRNA in leprosy patients using a predetermined set of genes as targets, providing interesting findings regarding the regulation of immune genes. However, using a predetermined set of genes restricted the possibility of finding new miRNAs that might be involved in different mechanisms of disease. Thus, we examined the miRNome of tuberculoid (TT and lepromatous (LL patients using both blood and lesional biopsies from classical leprosy patients (LP who visited the Dr. Marcello Candia Reference Unit in Sanitary Dermatology in the State of Pará and compared them with healthy subjects. Using a set of tools to correlate significantly differentially expressed miRNAs with their gene targets, we identified possible interactions and networks of miRNAs that might be involved in leprosy immunophysiopathology. Using this approach, we showed that the leprosy miRNA profile in blood is distinct from that in lesional skin as well as that four main groups of genes are the targets of leprosy miRNA: (1 recognition and phagocytosis, with activation of immune effector cells, where the immunosuppressant profile of LL and immunoresponsive profile of TT are clearly affected by miRNA expression; (2 apoptosis, with supportive data for an antiapoptotic leprosy profile based on BCL2, MCL1, and CASP8 expression; (3 Schwann cells (SCs, demyelination and epithelial–mesenchymal transition (EMT, supporting a role for different developmental or differentiation gene families, such as Sox, Zeb, and Hox; and (4 loss of sensation and neuropathic pain, revealing that RHOA, ROCK1, SIGMAR1, and aquaporin-1 (AQP1 may be involved in the loss of sensation or leprosy pain, indicating possible new therapeutic targets

    Even though health workers have treated all registered cases of leprosy in Sri Lanka with multiple drug therapy since 1982, it continues to be transmitted. The government has launched a social marketing and social mobilization campaign to reduce the incidence of leprosy. It has expanded the network of leprosy services. A national advertising program included mass media ads, posters, stickers on buses, and radio and television serials to create awareness of the early signs of leprosy and to reduce fear to leprosy. Health workers distributed leaflets and booklets to the general public and to new patients. The Anti-Leprosy Campaign of Sri Lanka organized 1-week health education programs for administrative officer, village leaders, religious leaders, teachers, and voluntary workers. Skin camps were set up to detect leprosy cases and to treat minor skin disorders. Teachers received flip charts on leprosy to help them teach colleagues and children about leprosy. All primary level staff, medical officers in hospital staff, and estate medical and paramedical staff have undergone special training on diagnosing leprosy and on reducing their fear of it. Almost every district has at least 1 leprosy control specialist. 2 leprosy control specialists work in those districts where leprosy is endemic Each district has a trained medical laboratory technician, who stains and interprets leprosy smears. In 1992, school, contact, and mass surveys have found 31, 149, and 225 new cases, respectively. Active case findings methods found 16.5% of new cases. 50% of new cases are self- reported, compared to less than 10% in 1989, suggesting increased awareness of early signs of leprosy and a reduced fear of it. 25 more clinics opened in 1991 to meet the demand for leprosy services.

The neural symptoms presented were sensory impairment (41, parasthesia (28, nerve enlargement (22, nerve tenderness (20, paresia (20, amyotrophy (8. Leprosy was diagnosed in ten out of the total number of patients studied. Leprosy was confirmed by the appearance of reactional neuritis (4, reversal reaction (2, biopsy of the hypoesthesic area (3 and the appearance of non-reactional cutaneous lesion. We reported an experience in the diagnosis of neuritic leprosy and its most frequent clinical presentation with which clinicians have to be acquainted. We can also state that the clinical follow-up was an effective strategy for the diagnosis of the disease when diagnostic facilities are not available or have not confirmed the diagnosis.

    2009-08-01

    Full Text Available Abstract Background Many epidemiological studies have shown that the genetic factors of the host play a role in the variability of clinical response to infection caused by M. leprae. With the purpose of identifying genes of susceptibility, the present study investigated the possible role of HLA-DRB1 and DQA1/DQB1 alleles in susceptibility to leprosy, and whether they account for the heterogeneity in immune responses observed following infection in a Southern Brazilian population. Methods One hundred and sixty-nine leprosy patients and 217 healthy controls were analyzed by polymerase chain reaction amplification and reverse hybridization with sequence-specific oligonucleotide probes and sequence-specific primers(One Lambda®, CA, USA. Results There was a positive association of HLA-DRB1*16 (*1601 and *1602 with leprosy per se (7.3% vs. 3.2%, P = 0.01, OR = 2.52, CI = 1.26–5.01, in accord with previous serological studies, which showed DR2 as a marker of leprosy. Although, HLA-DQA1*05 frequency (29.8% vs. 20.9%, P = 0.0424, OR = 1.61, CI = 1.09–2.39 was higher in patients, and HLA-DQA1*02 (3.0% vs. 7.5%, P = 0.0392, OR = 0.39, CI = 0.16 – 0.95 and HLA-DQA1*04 (4.0% vs. 9.1%, P = 0.0314, OR = 0.42, CI = 0.19 – 0.93 frequencies lower, P-values were not significant after the Bonferroni's correction. Furthermore, HLA-DRB1*1601 (9.0% vs. 1.8%; P = 0.0016; OR = 5.81; CI = 2.05–16.46 was associated with susceptibility to borderline leprosy compared to control group, and while HLA-DRB1*08 (11.2% vs. 1.2%; P = 0.0037; OR = 12.00; CI = 1.51 – 95.12 was associated with susceptibility to lepromatous leprosy, when compared to tuberculoid leprosy, DRB1*04 was associated to protection. Conclusion These data confirm the positive association of HLA-DR2 (DRB1*16 with leprosy per se, and the protector effect of DRB1*04 against lepromatous leprosy in Brazilian patients.

    Full Text Available Introduction Leprosy is a chronic disease that affects skin and peripheral nerves. Disease complications include reactional episodes and physical impairment. One World Health Organization (WHO goal of leprosy programs is to decrease the number of grade 2 impairment diagnoses by 2015. This study aims to evaluate clinical factors associated with the occurrence of leprosy reactions and physical impairment in leprosy patients. Methods We conducted a retrospective study of data from medical records of patients followed in two important centers for the treatment of leprosy in Aracaju, Sergipe, Brazil, from 2005 to 2011. We used the chi-square test to analyze associations between the following categorical variables: gender, age, operational classification, clinical forms, leprosy reactions, corticosteroid treatment, and physical impairment at the diagnosis and after cure. Clinical variables associated with multibacillary leprosy and/or reactional episodes and the presence of any grade of physical impairment after cure were evaluated using the logistic regression model. Results We found that men were more affected by multibacillary forms, reactional episodes, and grade 2 physical impairment at diagnosis. Leprosy reactions were detected in a total of 40% of patients and all were treated with corticosteroids. However, physical impairment was observed in 29.8% of the patients analyzed at the end of the treatment and our multivariate analysis associated a low dose and short period of corticosteroid treatment with persistence of physical impairments. Conclusions Physical impairment should receive an increased attention before and after treatment, and adequate treatment should be emphasized.

    No disease has been more closely associated with stigma than leprosy such that it has become a metaphor for stigma. Stigma has been difficult to measure and little research has been done on this issue. Stigma reduction has not been an important component of anti-leprosy program. The study was undertaken to measure the stigma associated with leprosy by using P scale which is used for assessing participation restriction of those affected by the disease. This comparative questionnaire based study was carried out in two sets of patients. Two groups of 30 patients each were studied. First group belonged to a Government run Leprosarium and group two from a tertiary care skin and leprosy centre. The study used the Participation (P) scale and data was collected by interviewing the patients. Participation restriction was defined as any score equal to and more than 13. Participation restriction was observed in 27 (90%) cases of group 1while participation restriction was present in only 7 (23.3%) subjects of group 2. It was observed that mean score of participation restriction in group 1 was quite high at 31.9 while it was only 8.3 for group 2. The participation restriction was directly related to the duration of disease and the grade of disability. Longer the duration of disease, greater was the likelihood of restriction. The participation restriction was found to be negatively correlated with the education. Recommendation about prevention of disability would require program about early diagnosis of nerve damage and subsequent action at the patient-family-community level and health care providers.

    Leprosy is a disease with different ratings due to the diversity of clinical manifestations. The most used classification by Reference Centers is the histopathological, which has been considered to have better specificity and sensitivity. Thus, the aim of this study was to determine the histopathological types of profile of Leprosy patients from different parts of Sergipe, Brazil, from 1985 to 2005. For this purpose, it was used histopathological diagnosis reports filed at Prof. Dr. Nestor Piva Memorial from 1985 to 2005. There were 2,102 reports with Leprosy diagnosis, from which 1,165 (55.4%) cases were women, 1,224 (58.2%) cases were of mixed race and 1,835 (87.3%) were from the metropolitan area of Aracaju/SE. The mean age was 36.62 year. The smear microscopy classified 1,669 (79.4%) lesions as paucibacillary and there was a predominance of tuberculoid and indeterminate forms. Men were more likely to be multibacillary, as well as being the lepromatous pole. The determination of histopathological forms and the knowledge about the association and the epidemiological profile are important tools to contribute to public health policies.

    Leprosy, caused by Mycobacterium leprae, is a chronic and progressive granulomatous disease affecting mainly the skin and the peripheral nervous system. If left unrecognized, the infection can lead to permanent nerve damage and disability. The clinical presentation depends on the immune response of the patient and can result in a wide spectrum of symptoms. Leprosy is a rare encounter in Scandinavia but remains endemic in some parts of the world, with some areas reporting an increasing incidence. We performed a retrospective record review of leprosy cases in Denmark from 1980 to 2010 with the purpose of presenting the most common geographical, demographic and clinical findings and to discuss the diagnostic and therapeutic challenges of patients with leprosy. In total 15 cases were reviewed. The majority (87%) of leprosy patients in Denmark were born in South- and Southeast Asia, and were presumed to have contracted the infection in their countries of origin. Patients were predominately young males (mean age: 28.6 years). Anaesthetic skin lesion with or without nerve enlargement were the most common clinical presentations (73%). Immunological leprosy reactions were seen in 40% of the cases. Diagnoses were based on clinical findings and skin biopsies. Treatment length varied but all patients received multidrug regimens. Leprosy should be kept in mind when encountering patients with suspicious skin lesions originating from leprosy endemic areas or with history of travel or work in the tropics. Due to the long incubation period with symptoms presenting long after immigration or return, clinicians often do not have the diagnosis in mind. The wide spectrum of symptoms and immunological reactions further complicates the diagnostic process. Treatment of leprosy and the complicated immunological reactions, which frequently accompanies the infection, should be performed in collaboration with a specialist.

    2016-01-01

    Full Text Available The persistence of Mycobacterium leprae (M. leprae infection is largely dependent on the types of host immune responses being induced. Macrophage, a crucial modulator of innate and adaptive immune responses, could be directly infected by M. leprae. We therefore postulated that M. leprae-infected macrophages might have altered immune functions.Here, we treated monocyte-derived macrophages with live or killed M. leprae, and examined their activation status and antigen presentation. We found that macrophages treated with live M. leprae showed committed M2-like function, with decreased interleukin 1 beta (IL-1beta, IL-6, tumor necrosis factor alpha (TNF-alpha and MHC class II molecule expression and elevated IL-10 and CD163 expression. When incubating with naive T cells, macrophages treated with live M. leprae preferentially primed regulatory T (Treg cell responses with elevated FoxP3 and IL-10 expression, while interferon gamma (IFN-gamma expression and CD8+ T cell cytotoxicity were reduced. Chromium release assay also found that live M. leprae-treated macrophages were more resistant to CD8+ T cell-mediated cytotoxicity than sonicated M. leprae-treated monocytes. Ex vivo studies showed that the phenotype and function of monocytes and macrophages had clear differences between L-lep and T-lep patients, consistent with the in vitro findings.Together, our data demonstrate that M. leprae could utilize infected macrophages by two mechanisms: firstly, M. leprae-infected macrophages preferentially primed Treg but not Th1 or cytotoxic T cell responses; secondly, M. leprae-infected macrophages were more effective at evading CD8+ T cell-mediated cytotoxicity.

  18. Curing the stigma of leprosy.

    The stigma of leprosy is a real phenomenon in many people's lives that affects their physical, psychological, social and economical well-being. There are many causes for this damaging image of leprosy. There is no one easy answer to dispelling this image; it is something that has to be done in partnership with communities and patients. Many papers document the effects of stigma, but few discuss or trial solutions. Education and media campaigns counteract false beliefs about leprosy and raise awareness of new advances in the field. Leprosy care is increasingly provided in an integrated setting showing patients and their communities that leprosy is not a disease apart. Physical and socio-economic rehabilitation is worthwhile in restoring self worth and status in the community and helps patients to find employment. Group counselling can allow those with leprosy to talk about their feelings and experiences to empower one another. Gradually attitudes towards leprosy are changing, but there is still much to be done if the underlying menace of stigma is to be dealt with. We as health professionals must be prepared to make the first move and give that first touch. Certainly more research is needed. In the highly endemic countries the road to elimination may yet be long. Perhaps with effort we will one day be able not only to treat the disease, but also to cure the stigma of leprosy, and make that road an easier one.

    Full Text Available The involvement of skeletal striated muscle in leprosy is considered secondary due to peripheral neuropathy, but some studies point it to a primary muscle lesion. In order to investigate the muscle involvement in leprosy, we studied 40 patients (lepromatous 23, tuberculoid 13, borderline 2 and indeterminate 2. The motor nerve conduction of the peroneal nerves had a reduction of the velocity, decreased compound muscle action potential and sometimes absence of potentials. The electromyographic study of the anterior tibial muscle showed signs of recent and chronic denervation in 77.5% of the cases and no myopathic potentials. The anterior tibial muscle biopsy revealed denervation in 45% of the cases, interstitial inflammatory myopathy in 30% and mixed (myopathic and neuropathic pattern in 12.5%. Acid fast bacillus was detected in 25% of the cases, always in the interstitial tissue. Inflammatory reaction was present in the interstitial space and in patients with the lepromatous type. The histological findings clearly defined the presence of the so-called "Leprous Interstitial Myositis" on the top of denervation signs.O envolvimento do músculo estriado na lepra é considerado secundário à lesão dos nervos periféricos, mas alguns estudos relataram acometimento muscular primário. A fim de verificar esta controvérsia estudamos 40 pacientes com lepra, sendo 23 da forma lepromatosa, 13 da tuberculoide, 2 borderline e 2 indeterminada. Realizamos a neurocondução do nervo peroneiro, junto com eletromiografia e biópsia do músculo tibial anterior. Encontramos redução de velocidade de condução, da amplitude e algumas vezes ausência de potenciais no nervo peroneiro. A eletromiografia do tibial anterior mostrou sinais de desinervação recente e crônica em 77,5% dos casos e não foi encontrada evidência de padrão "miopático". A biópsia do músculo tibial anterior revelou desinervação em 45% dos casos, miopatia inflamatória intersticial em

    Full Text Available Background: Leprosy has been a major public-health problem in many developing countries for centuries. According to the National Leprosy Elimination Programme report of March 2012, there were a total of about 0.13 million cases of leprosy in India, 9.7% of which were children. Numerous studies have investigated child leprosy amongst reported cases however, studies pertaining to proportion and characteristics of undetected childhood cases in the community are very few. Aim: To examine the clinical, bacteriological, and histopathological characteristics of newly detected child leprosy cases in the community. Methods: The population survey conducted from June to September 2007 and the defined rural areas, which included five primary health centers of Panvel Taluka, in Raigad district and urban areas, which included M-east ward of the municipal corporation of greater Mumbai of western Maharashtra, India. Results: House-to-house survey yielded 32 and 37 so far, undetected child cases of leprosy in the rural and urban region, and the prevalence rate was 10.5 and 1.5 per 10,000, respectively. The age of child leprosy cases detected, ranged from 3 to 14 years with a mean of 10.06 ± 3.35 years in the rural and 9.97 ± 3.12 years in the urban area. Most of the cases were paucibacillary (62%. A large proportion of children (49% had single skin lesion (SSL. Of the 19 SSL cases examined histopathologically, 15 (99% showed features of borderline tuberculoid, 1 (5% borderline lepromatous and 3 (16% had indeterminate type of leprosy. Tuberculoid leprosy was not seen in any, indicating less likelihood of self-healing. Overall, three cases had deformity (grade 1 = 1 and grade 2 = 2 and 31% of multibacillary cases were smear positive. Conclusion: The clinical, bacteriological, and histopathological characteristics of newly detected child cases in the community evidently indicate the grave nature of the problem of undetected child leprosy, recent active

    Advanced lesions of the face, nasopharynx, and oropharynx have played an important role in the medical and social history of Hansen's disease. Renaissance artists included detailed portrayals of these lesions in some of their paintings, a testimony not only to their artistic skill and powers of observation but also to the common presence of these patients in European cities and towns of the period. The disease is now understood as a broad immunologic spectrum of host responses to Mycobacterium leprae, with a variety of clinical and pathologic manifestations in nerve, soft tissues, and bone. This review incorporates the findings of 2 extraordinary studies (one from Europe and the other from Japan) of pharyngeal and facial lesions. In the 1950s, studies of skeletal remains from the churchyard of a Danish leprosarium revealed a triad of maxillofacial lesions unique to leprosy and designated facies leprosa. In pre-World War II Japan, before effective treatment had been discovered, a prominent otorhinolaryngologist studying oropharyngeal and nasopharyngeal lesions prepared watercolor illustrations of the natural progression of untreated Hansen's disease. As a result of effective antimicrobial therapy, such advanced lesions are now rarely seen, but the presenting signs and symptoms of leprosy still occasionally arise in the nasal and oral mucosa. The nasopharynx and oropharynx may be important early sites of inoculation and infection by M leprae, and they require additional emphasis in worldwide efforts toward early diagnosis and treatment of Hansen's disease.

    This paper, the last in a series of three on 'feline leprosy', provides a detailed description of disease referable to the previously unnamed species, Candidatus 'Mycobacterium lepraefelis', a close relative of the human pathogens Mycobacterium leprae and Mycobacterium lepromatosis. Cases were sourced retrospectively and prospectively for this observational study, describing clinical, geographical and molecular microbiological data for cats definitively diagnosed with Candidatus 'M lepraefelis' infection. A total of 145 cases of feline leprosy were scrutinised; 114 'new' cases were sourced from the Victorian Infectious Diseases Reference Laboratory (VIDRL) records, veterinary pathology laboratories or veterinarians, and 31 cases were derived from six published studies. Thirty-eight cats were definitively diagnosed with Candidatus 'M lepraefelis' infection. Typically, cats tended to be middle-aged or older when first infected, with a male predilection. Affected cats typically had widespread cutaneous lesions, in some cases after initially localised disease. Advanced cases were often systemically unwell. All cats had outdoor access. The histological picture was lepromatous in the majority of patients, although two cases had tuberculoid disease. In one case that underwent necropsy, lesions were evident in the liver, spleen and lungs. Treatment was varied, although most cats received a combination of oral clarithromycin and rifampicin. Prognosis for recovery was variable, but typically poor. Candidatus 'M lepraefelis' typically causes high bacterial index (lepromatous) feline leprosy that in some cases progresses to systemic mycobacteriosis. The disease has a variable clinical course and prognosis. Many cases either died or were euthanased due to the infection. Multilocus sequence analysis reveals a heterogeneous picture and further analysis of draft genome sequencing may give clues to the taxonomy and epidemiology of this organism.

    Full Text Available Abstract Background Caused by Mycobacterium leprae (ML, leprosy presents a strong immune-inflammatory component, whose status dictates both the clinical form of the disease and the occurrence of reactional episodes. Evidence has shown that, during the immune-inflammatory response to infection, the growth hormone/insulin-like growth factor-I (GH/IGF-I plays a prominent regulatory role. However, in leprosy, little, if anything, is known about the interaction between the immune and neuroendocrine systems. Methods In the present retrospective study, we measured the serum levels of IGF-I and IGBP-3, its major binding protein. These measurements were taken at diagnosis in nonreactional borderline tuberculoid (NR BT, borderline lepromatous (NR BL, and lepromatous (NR LL leprosy patients in addition to healthy controls (HC. LL and BL patients who developed reaction during the course of the disease were also included in the study. The serum levels of IGF-I, IGFBP-3 and tumor necrosis factor-alpha (TNF-α were evaluated at diagnosis and during development of reversal (RR or erythema nodosum leprosum (ENL reaction by the solid phase, enzyme-labeled, chemiluminescent-immunometric method. Results The circulating IGF-I/IGFBP-3 levels showed significant differences according to disease status and occurrence of reactional episodes. At the time of leprosy diagnosis, significantly lower levels of circulating IGF-I/IGFBP-3 were found in NR BL and NR LL patients in contrast to NR BT patients and HCs. However, after treatment, serum IGF-I levels in BL/LL patients returned to normal. Notably, the levels of circulating IGF-I at diagnosis were low in 75% of patients who did not undergo ENL during treatment (NR LL patients in opposition to the normal levels observed in those who suffered ENL during treatment (R LL patients. Nonetheless, during ENL episodes, the levels observed in RLL sera tended to decrease, attaining similar levels to those found in NR LL patients

    Leprosy control activities in Yemen are reviewed historically and up to the present time. Since 1983 the World Health Organization's multidrug therapy has been used in the National Leprosy Control Programme. Current activities are carried out in 63 leprosy clinics distributed all over the country and staffed by trained primary health care workers and medical assistants. In Yemen leprosy prevalence has declined from 1400 per 10,000 population in 1990 to 647 in 1997. Over the same period, new case detection rates per 10,000 population increased from 185 to 517. A backlog of leprosy cases continues to transmit the disease in Yemen.

    Full Text Available BACKGROUND: Neuropathic pain has been little studied in leprosy. We assessed the prevalence and clinical characteristics of neuropathic pain and the validity of the Douleur Neuropathique 4 questionnaire as a screening tool for neuropathic pain in patients with treated leprosy. The association of neuropathic pain with psychological morbidity was also evaluated. METHODOLOGY/PRINCIPAL FINDINGS: Adult patients who had completed multi-drug therapy for leprosy were recruited from several Bombay Leprosy Project clinics. Clinical neurological examination, assessment of leprosy affected skin and nerves and pain evaluation were performed for all patients. Patients completed the Douleur Neuropathique 4 and the 12-item General Health Questionnaire to identify neuropathic pain and psychological morbidity. CONCLUSIONS/SIGNIFICANCE: One hundred and one patients were recruited, and 22 (21.8% had neuropathic pain. The main sensory symptoms were numbness (86.4%, tingling (68.2%, hypoesthesia to touch (81.2% and pinprick (72.7%. Neuropathic pain was associated with nerve enlargement and tenderness, painful skin lesions and with psychological morbidity. The Douleur Neuropathique 4 had a sensitivity of 100% and specificity of 92% in diagnosing neuropathic pain. The Douleur Neuropathique 4 is a simple tool for the screening of neuropathic pain in leprosy patients. Psychological morbidity was detected in 15% of the patients and 41% of the patients with neuropathic pain had psychological morbidity.

    Here we report a unique case of tuberculoid leprosy and cytomegalovirus retinitis in a 27-year-old female patient with AIDS, suggestive of highly active antiretroviral therapy (HAART)-induced immune restoration disease. After initiation of HAART, the patient presented with decreased visual acuity, hypoesthetic patch with local nerve thickening, and an increase in her CD4+ T cell count. On further investigations cytomegalovirus retinitis and tuberculoid leprosy were confirmed. To our knowledge no case with such a co-existence has previously been reported.

    2016-01-01

    Full Text Available Five years after both right ulnar and median nerve decompression for paraesthesias and palsy, a patient, coming from Nigeria but living in Italy, came to our unit claiming to have persistent pain and combined median and ulnar palsy. Under suspicion of leprosy, skin and left sural nerve biopsy were performed. Skin tests were negative, but Schwann cells resulted as positive for acid-fast bacilli (AFB, leading to the diagnosis of Pure Neuritic Leprosy (PNL. The patient was given PB multidrug therapy and recovered from pain in two months. After nine months both High Resolution Ultrasonography (HRUS and Magnetic Resonance Imaging (MRI were performed, revealing thickening of the nerves. Since demyelination is common in PNL, the Authors started to use Diffusion Tensor Imaging Tractography (DTIT to get better morphological and functional data about myelination than does the traditional imaging. DTIT proved successful in showing myelin discontinuity, reorganization, and myelination, and the Authors suggest that it can give more information about the evolution of the disease, as well as further indications for surgery (nerve decompression, nerve transfers, and babysitting for distal effector protection, and should be added to traditional imaging tools in leprosy.

    Immunological characterization of mycobacterial peptides may help not only in the preparation of a vaccine for leprosy but also in developing in vitro T-cell assays that could perhaps be used as an in vitro correlate for treatment outcome. The main goal of this study was to evaluate the use of Mycobacterium bovis recombinant 32-kDa protein (r32-kDa) antigen-stimulated T-cell assay as a surrogate marker for treatment outcome and monitor vitamin D receptor (VDR)-mediated anti-microbial responses during multidrug therapy (MDT) in leprosy. Newly diagnosed tuberculoid and lepromatous leprosy patients were enrolled and followed up during their course of MDT at 6 and 12 months. IFN-γ, IL-10, IL-17 and IL-23 levels in culture supernatants and expression of VDR, TLR2, LL37 and DEFB in r32-kDa-stimulated PBMCs were measured. Controls comprised household contacts (HHCs) and healthy endemic subjects (HCs). Significant differences were observed in the levels of IFN-γ, IL-17, IL-23, VDR and anti-microbial peptides LL37 and DEFB after treatment and when compared with that of HHCs and HCs, respectively. These findings suggest that responses to r32-kDa antigen reflect an improved immunological and anti-microbial response in leprosy patients during therapy, thereby indicating its potential use as an immune correlate in the treatment of leprosy patients. © The Japanese Society for Immunology. 2016.

    Overpopulation of urban areas results from constant migrations that cause disordered urban growth, constituting clusters defined as sets of people or activities concentrated in relatively small physical spaces that often involve precarious conditions. Aim. Using residential grouping, the aim was to identify possible clusters of individuals in São José do Rio Preto, Sao Paulo, Brazil, who have or have had leprosy. Methods. A population-based, descriptive, ecological study using the MapInfo and CrimeStat techniques, geoprocessing, and space-time analysis evaluated the location of 425 people treated for leprosy between 1998 and 2010. Clusters were defined as concentrations of at least 8 people with leprosy; a distance of up to 300 meters between residences was adopted. Additionally, the year of starting treatment and the clinical forms of the disease were analyzed. Results. Ninety-eight (23.1%) of 425 geocoded cases were located within one of ten clusters identified in this study, and 129 cases (30.3%) were in the region of a second-order cluster, an area considered of high risk for the disease. Conclusion. This study identified ten clusters of leprosy cases in the city and identified an area of high risk for the appearance of new cases of the disease. PMID:24288467

    Full Text Available Mucus and lymph smears collected from leprosy patients (9 and their household contacts (44 in the Caño Mochuelo Indian Reservation, Casanare, Colombia, were examined with monoclonal antibodies (MoAb against Mycobacterium leprae. The individuals studied were: 5 borderline leprosy (BB patients, 4 with a lepromatous leprosy (LL, all of whom were undergoing epidemiological surveillance after treatment and 44 household contacts: 21 of the LL and 23 contacts of the BB patients. The MoAb were reactive with the following M. leprae antigens: 65 kd heat shock protein, A6; soluble antigen G7 and complete antigen, E11. All the samples were tested with each of the MoAb using the avidin-biotin-peroxidase technique and 3,3 diaminobenzidine as chromogen. The patients and household contacts studied were all recorded as Ziehl-Neelsen stain negative. The MoAb which showed optimal reaction was G7, this MoAb permited good visualization of the bacilli. Five patients with BB diagnosis and one with LL were positive for G7; of the BB patients' household contacts, 9 were positive for G7; 7 of the LL patients' household contacts were positive for the same MoAb. MoAb G7 allowed the detection of bacillar Mycobacterium spp. compatible structures in both patients and household contacts. G7 permited the visualization of the complete bacillus and could be used for early diagnosis and follow-up of the disease in patients.

  19. Predicting neuropathy and reactions in leprosy at diagnosis and before incident events-results from the INFIR cohort study.

    Directory of Open Access Journals (Sweden)

    W Cairns S Smith

    Full Text Available BACKGROUND: Leprosy is a disease of skin and peripheral nerves. The process of nerve injury occurs gradually through the course of the disease as well as acutely in association with reactions. The INFIR (ILEP Nerve Function Impairment and Reactions Cohort was established to identify clinically relevant neurological and immunological predictors for nerve injury and reactions. METHODOLOGY/PRINCIPAL FINDINGS: The study, in two centres in India, recruited 188 new, previously untreated patients with multi-bacillary leprosy who had no recent nerve damage. These patients underwent a series of novel blood tests and nerve function testing including motor and sensory nerve conduction, warm and cold detection thresholds, vibrometry, dynamometry, monofilament sensory testing and voluntary muscle testing at diagnosis and at monthly follow up for the first year and every second month for the second year. During the 2 year follow up a total of 74 incident events were detected. Sub-clinical changes to nerve function at diagnosis and during follow-up predicted these new nerve events. Serological assays at baseline and immediately before an event were not predictive; however, change in TNF alpha before an event was a statistically significant predictor of that event. CONCLUSIONS/SIGNIFICANCE: These findings increase our understanding of the processes of nerve damage in leprosy showing that nerve function impairment is more widespread than previously appreciated. Any nerve involvement, including sub-clinical changes, is predictive of further nerve function impairment. These new factors could be used to identify patients at high risk of developing impairment and disability.

    INTRODUCTION Leprosy, an infectious disease caused by Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy. OBJECTIVES Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control. EVIDENCE ACQUISITION The historiological method was applied using document review, complemented by interviews with experts on leprosy and its control. Archived documents, medical records, disease prevalence censuses conducted since 1942, and incidence and prevalence statistics for 1960-2015 from the Ministry of Public Health's National Statistics Division were reviewed. Reports and scientific literature published on the Program and the history of leprosy in Cuba were also reviewed. DEVELOPMENT Leprosy has been documented in Cuba since 1613. In 1938, the Leprosy Foundation was created with ten dispensaries nationwide for diagnosis and treatment. The first National Leprosy Control Program was established in 1962, implemented in 1963 and revised five times. In 1972, leper colonies were closed and treatment became ambulatory. In 1977, rifampicin was introduced. In 1988, the Program instituted controlled, decentralized, community-based multidrug treatment and established the criteria for considering a patient cured. In 2003, it included actions aimed at early diagnosis and prophylactic treatment of contacts. Since 2008, it prioritizes actions directed toward the population at risk, maintaining five-year followup with dermatological and neurological examination. Primary health care carries out diagnostic and treatment

    Leprosy and tuberculosis (TB) both are still rampant in India. Leprosy predominantly presents through skin manifestations whereas cutaneous manifestations of TB though not so frequent but are not rare. Lupus vulgaris (LV), the commonest of all cutaneous manifestations of TB, mimics leprosy very closely and may prompt the examiner to misdiagnose leprosy, especially, by health workers (HW), in a field situation, where leprosy is diagnosed and treated on clinical basis alone as per NLEP guidelines. Because of existing stigmata, such wrong diagnosis can put the patient and the party under psychological stress and creates unnecessary complications.

    Full Text Available Mycobacterium leprae infects skin and peripheral nerves causing deformities and disability. The M. leprae bacterium binds to ErbB2 on the Schwann cell surface causing demyelination and favoring spread of the bacilli and causing nerve injury. Polymorphisms at the ERBB2 gene were previously investigated as genetic risk factors for leprosy in two Brazilian populations but with inconsistent results. Herein we extend the analysis of ERBB2 variants to a third geographically distinct population in Brazil. Our results show that there is no association between the genotyped SNPs and the disease (p > 0.05 in this population. A gene set or pathway analysis under the genomic region of ERBB2 will be necessary to clarify its regulation under M. leprae stimulus.

    Leprosy and tuberculosis (TB) are endemic to India, however, their coinfection is not frequently encountered in clinical practice. Here, we report a 32-year-old female patient who presented with a history of high-grade intermittent fever, cough and painless skin lesions since a month, along with bilateral claw hand (on examination). The haematological profile was suggestive of anaemia of chronic disease, chest radiograph showed consolidation, sputum smears were positive for Mycobacterium tuberculosis, and skin slit smear confirmed leprosy. The patient was prescribed WHO recommended multidrug therapy for multibacillary leprosy with three drugs. Additionally, prednisolone was added to her regimen for 2 weeks to treat the type 2 lepra reaction. For treatment of TB, she was placed on the standard 6-month short course chemotherapy. She was lost to follow-up, and attempts were made to contact her. Later, it came to our notice that she had discontinued medications and passed away 3 months after diagnosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Nine burials excavated from the Magdalen Hill Archaeological Research Project (MHARP) in Winchester, UK, showing skeletal signs of lepromatous leprosy (LL) have been studied using a multidisciplinary approach including osteological, geochemical and biomolecular techniques. DNA from Mycobacterium leprae was amplified from all nine skeletons but not from control skeletons devoid of indicative pathology. In several specimens we corroborated the identification of M. leprae with detection of mycolic acids specific to the cell wall of M. leprae and persistent in the skeletal samples. In five cases, the preservation of the material allowed detailed genotyping using single-nucleotide polymorphism (SNP) and multiple locus variable number tandem repeat analysis (MLVA). Three of the five cases proved to be infected with SNP type 3I-1, ancestral to contemporary M. leprae isolates found in southern states of America and likely carried by European migrants. From the remaining two burials we identified, for the first time in the British Isles, the occurrence of SNP type 2F. Stable isotope analysis conducted on tooth enamel taken from two of the type 3I-1 and one of the type 2F remains revealed that all three individuals had probably spent their formative years in the Winchester area. Previously, type 2F has been implicated as the precursor strain that migrated from the Middle East to India and South-East Asia, subsequently evolving to type 1 strains. Thus we show that type 2F had also spread westwards to Britain by the early medieval period. PMID:23638071

    Full Text Available A Borderline Lepromatous (BL leprosy case was treated with Mercurius solubilis, a homoeopathic medicine for two years. The clinical, immunological and histological assessment of the patient before and after treatment was recorded. The patient showed appreciable improvement in clinical signs and symptoms. Lesions on the skin almost disappeared; no swelling of hand and feet was noted along with disappearance of infiltration on eye brows. Nodular lesions on both the ear lobes diminished remarkably. Regain of sensation to touch, pain and pressure were noted and their test responses were normal. Slit skin smears were negative from all sites with 0 Bacteriological Index [BI] which was positive for acid fast bacilli [AFB] with an average of 4+ BI before treatment. Histologic study revealed absence of granuloma in dermis except the presence of occasional clusters of lymphocytes. Lepromin reaction which was negative before treatment was positive with 14 mm after 2 years of treatment. Estimation of different cytokines after completion of treatment showed appreciable changes with remarkable reduction in the levels of proinflammatory cytokines (IFN and TNF.

Um homem de 58 anos foi admitido com edema de membros inferiores e dispnéia. Na admissão, havia retenção de escórias nitrogenadas, anemia, hipercalemia e acidose metabólica, com necessidade de hemodiálise. Referia história de hanseníase virchoviana. Foi realizada biopsia renal, compatível com amiloidose. O paciente evoluiu estável, sem recuperação da função renal, permanecendo em tratamento hemodialítico. A hanseníase deve ser investigada em todo paciente com perda de função renal, sobretudo naqueles que apresentam lesões cutâneas ou outras manifestações sugestivas de hanseníase.Renal involvement in leprosy includes glomerulonephritis, amyloidosis and tubulointerstitial nephritis. A 58-year-old man was admitted with complaints of lower limb edema and dyspnea. At admission, nitrogen retention, anemia, hyperkalemia and metabolic acidosis were observed, requiring hemodialysis. The patient had a history of lepromatous leprosy. A renal biopsy was performed that was compatible with amyloidosis. The patient had a stable outcome, but without renal function recovery and remained on regular hemodialysis. Leprosy should be investigated in every patient with renal function loss, particularly in those with cutaneous lesions or other manifestations suggestive of leprosy.

    Full Text Available Objective: To explore the psychosocial condition and consequences of the people affected by leprosy and the related deformity in some selected areas of Bangladesh. Methods: A cross-sectional study was conducted from July to December 2015 among 92 leprosy-affected people. A pretested semi-structure questionnaire was used for collecting data by face to face interview from both the low prevalent areas of Khulna and the high prevalent area of Rangpur Division in Bangladesh. Results: Nearly two-fifth of respondents were observed having deformity. Among them, around four-fifth was from Khulna region, about half were above 50 years of age and more than half had monthly family income lower than 5 000 BDT. The development of deformity is found having highly significant association with region (P < 0.001, residence (P < 0.004, and family income (P < 0.004. Differences in consequences between ‘with deformity’ and ‘without deformity’ were found very high. About 65% of the respondents with deformity ‘think less’ of himself, and nearly 60% felt ashamed or embarrassed, 53% had to change job, and 47% was used to think having less respect in the society where the percentage was much lower in all cases to ‘without deformity’ group. Conclusions: Early diagnosis and start multidrug therapy at the earliest stages have chanced to reduce the leprosy-resulted deformity, disfigurement and disability. For those who already have had some nerve damages, health education is highly important to prevent further injury and hence psychosocial consequences.

    To evaluate hand muscle weakness detected through dynamometry as an indicator for change in motor nerve function detected by Voluntary Muscle Testing (VMT) of ulnar and median nerves. The research was carried out as part of the INFIR Cohort Study among 303 subjects newly diagnosed with MB leprosy in two centres in UP state, northern India. To assess grip strength, key pinch and pulp-to-pulp pinch we adapted the cuffs of adult and neonatal sphygmomanometers. The testing was carried out at diagnosis and at each visit during a 2-year follow-up. 303 subjects with newly diagnosed MB leprosy were included in the study. We found statistically significant differences in grip strength, key pinch and pulp-to-pulp pinch between groups defined by ulnar VMT grades at time of diagnosis. There was also a statistically significant difference in hand grip between groups defined by median VMT at diagnosis. In each case, strength tended to reduce with increasing motor involvement. We explored reduction in grip strength, key pinch or pulp-to-pulp pinch as indicators of change in ulnar VMT during follow-up. A 25% reduction over two visits was the most effective indicator. Changes were also associated with marginal changes in motor and sensory nerve function, most commonly associated with Type I reactions. Dynamometry is recommended as an additional method that may be used to monitor changes in nerve function in leprosy, particularly in subjects with early motor impairment of the ulnar nerve.

    Full Text Available Catastrophic antiphospholipid syndrome is an acute and life threatening variant of antiphospholipid syndrome with a high mortality rate. Many infections are known to be accompanied by the thrombotic manifestations of this syndrome. We came across a patient of leprosy who developed bowel ischaemia secondary to mesenteric venous thrombosis as a part of catastrophic antiphospholipid syndrome and later on succumbed. We thereby wish to highlight the need for early diagnosis and aggressive treatment of this potentially fatal condition in patients with infections.

    Leprosy is a chronic infectious disease caused by Mycobacterium leprae, which primarily infects macrophages and Schwann cells, affecting skin and peripheral nerves. Clinically, the most common form of identification is through the observation of anesthetic lesions on skin; however, up to 30% of infected patients may not present this clinical manifestation. Currently, the gold standard diagnostic test for leprosy is based on skin lesion biopsy, which is invasive and presents low sensibility for suspect cases. Therefore, the development of a fast, sensible and noninvasive method that identifies infected patients would be helpful for assertive diagnosis. The aim of this work was to identify lipid markers in leprosy patients directly from skin imprints, using a mass spectrometric analytical strategy. For skin imprint samples, a 1 cm(2) silica plate was gently pressed against the skin of patients or healthy volunteers. Imprinted silica lipids were extracted and submitted to direct-infusion electrospray ionization high-resolution mass spectrometry (ESI-HRMS). All samples were differentiated using a lipidomics-based data workup employing multivariate data analysis, which helped electing different lipid markers, for example, mycobacterial mycolic acids, inflammatory and apoptotic molecules were identified as leprosy patients' markers. Otherwise, phospholipids and gangliosides were pointed as healthy volunteers' skin lipid markers, according to normal skin composition. Results indicate that silica plate skin imprinting associated with ESI-HRMS is a promising fast and sensible leprosy diagnostic method. With a prompt leprosy diagnosis, an early and effective treatment could be feasible and thus the chain of leprosy transmission could be abbreviated.

  18. Specific antigen serologic tests in leprosy: implications for epidemiological surveillance of leprosy cases and household contacts

    Directory of Open Access Journals (Sweden)

    Ana Paula Mendes Carvalho

    Full Text Available BACKGROUND There is a lack of straightforward tests for field application and known biomarkers for predicting leprosy progression in infected individuals. OBJECTIVE The aim was to analyse the response to infection by Mycobacterium leprae based on the reactivity of specific antigens: natural disaccharide linked to human serum albumin via an octyl (NDOHSA, a semisynthetic phenolic glycolipid-I (PGL-I; Leprosy Infectious Disease Research Institute Diagnostic-1 (LID-1 and natural disaccharide octyl - Leprosy Infectious Disease Research Institute Diagnostic-1 (NDOLID. METHODS The study population consisted of 130 leprosy cases diagnosed between 2010 and 2015 and 277 household contacts. An enzyme-linked immunosorbent assay (ELISA was used to analyse the reactivity of antibodies against NDOHSA, LID-1 and NDOLID. The samples and controls were tested in duplicate, and the antibody titer was expressed as an ELISA index. Data collection was made by home visits with application of questionnaire and dermatological evaluation of all household contacts to identify signs and symptoms of leprosy. FINDINGS Significant differences in the median ELISA results were observed among leprosy cases in treatment, leprosy cases that had completed treatment and household contacts. Higher proportions of seropositivity were observed in leprosy cases in treatment. Seropositivity was also higher in multibacillary in relation to paucibacillary, with the difference reaching statistical significance. Lower titers were observed among cases with a longer treatment time or discharge. For household contacts, the differences according to the clinical characteristics of the leprosy index case were less pronounced than expected. Other factors, such as the endemicity of leprosy, exposure outside the residence and genetic characteristics, appeared to have a greater influence on the seropositivity. MAIN CONCLUSIONS Serologic tests could be used as auxiliary tools for determining the

  19. Degree of skin denervation and its correlation to objective thermal sensory test in leprosy patients.

    Directory of Open Access Journals (Sweden)

    Ismael Alves Rodrigues Júnior

    Full Text Available BACKGROUND: Leprosy is an infectious disease affecting skin and peripheral nerves resulting in increased morbidity and physical deformities. Early diagnosis provides opportune treatment and reduces its complications, relying fundamentally on the demonstration of impaired sensation in suggestive cutaneous lesions. The loss of tactile sensitivity in the lesions is preceded by the loss of thermal sensitivity, stressing the importance of the thermal test in the suspicious lesions approach. The gold-standard method for the assessment of thermal sensitivity is the quantitative sensory test (QST. Morphological study may be an alternative approach to access the thin nerve fibers responsible for thermal sensitivity transduction. The few studies reported in leprosy patients pointed out a rarefaction of thin dermo-epidermal fibers in lesions, but used semi-quantitative evaluation methods. METHODOLOGY/PRINCIPAL FINDINGS: This work aimed to study the correlation between the degree of thermal sensitivity impairment measured by QST and the degree of denervation in leprosy skin lesions, evaluated by immunohistochemistry anti-PGP 9.5 and morphometry. Twenty-two patients were included. There were significant differences in skin thermal thresholds among lesions and contralateral skin (cold, warm, cold induced pain and heat induced pain. The mean reduction in the density of intraepidermal and subepidermal fibers in lesions was 79.5% (SD = 19.6 and 80.8% (SD = 24.9, respectively. CONCLUSIONS/SIGNIFICANCE: We observed a good correlation between intraepidermal and subepidermal fibers deficit, but no correlation between these variables and those accounting for the degree of impairment in thermal thresholds, since the thin fibers rarefaction was homogeneously intense in all patients, regardless of the degree of sensory deficit. We believe that the homogeneously intense denervation in leprosy lesions should be objective of further investigations focused on its

    Across-sectional epidemiological study was carried out at a Leprosy Referral Hospital in Delhi to assess the nutritional status of multibacillary leprosy patients in comparison to the general population using BMI. 150 people affected with multibacillary leprosy were included in the study, of whom 108 (72%) had WHO Grade 2 disability. 100 non leprosy patients were also included as a control group. Socio-demographic and clinical details as well as their height and weight were measured and the BMI computed. The findings clearly showed that under-nutrition (BMI disability made the incidence of under-nutrition more likely. The duration of disease, number of lesions or bacterial index had no impact on the level of nutrition. There may be multiple factors working together to lead to this under-nutrition and these are discussed briefly. If, we aim to provide high quality services with a holistic approach, a mandatory BMI should be calculated for every patient and if under nourished, a qualitative diet summary should be done and suitable nutritional advice given. Further, studies are needed for a better understanding of the occurrence and progression of under-nutrition in leprosy to find efficient ways to combat this problem.

    Leprosy is a chronic infectious disease that has stigmatised people affected since ancient times until now. This has resulted in difficulties in the lives of those affected. This literature review was conducted to understand the concept, causes, and determinants of stigma in leprosy. Electronic searches were undertaken using PubMed (Medline), CINAHL and PsycInfo databases. The internet was searched through Google Scholar for papers not found in these databases. The main inclusion criteria were papers related to stigma or leprosy written in Thai or English. After searching the databases, 84 papers were identified, 3 were removed because of duplication and parallel publication, and 20 were removed on abstract screening. After reading 61 full papers, 7 were excluded. Finally, 54 were included in this review. It was found that the concept of stigma involves not only characteristics considered undesirable, but also the social context of the individual or group. Reported causes and determinants of stigma related to leprosy are the external manifestations of the disease, cultural and religious beliefs, fear of transmission, association with people considered inferior and public health-related interventions. Stigma is a complex phenomenon that has multiple causes, often linked to the cultural context in which it occurs. Despite this, many similarities were found in leprosy-related stigma across countries and cultures, which would facilitate the development of interventions.

    Leprosy was a well-recognized and dreaded disease in medieval Europe. The disease is reported to have reached Germany with the Roman invasion and it was present in Scandinavia in the first centuries AD. This paper estimates and analyzes the frequency of leprosy among adult people buried in one of five medieval cemeteries in the city of Schleswig. Seven different dichotomous osteological lesions indicative of leprosy were analyzed, and it was possible to score at least one of these conditions on 350 adult skeletons (aged 15 or older). The scores were transformed to a statistic indicating the likelihood that the person to whom the skeleton belonged suffered from leprosy. It was found that the frequency of leprosy in the five cemeteries varied between 9 and 44%. Four of the five cemeteries showed frequencies ranging from 35 and 44% and with no statistically significant differences among them. The fifth cemetery showed a significantly lower frequency of leprosy (9%). The distribution of female age at death does not appear to be affected by leprosy status. This means that females experienced a considerably elevated risk of dying once they had contracted leprosy as the disease usually has a mid-adulthood age of onset. In four of the five cemeteries males with leprosy died in higher ages than men without leprosy--in two of the cemeteries the difference was statistically significant. This indicates that leprosy usually added less to the risk of dying among men than among women in medieval Schleswig.

    Full Text Available Leprosy is among the world′s oldest and most dreaded diseases and it has been synonymous with stigma and discrimination due to the hideous deformities it produced, mystery around its aetiology and transmission and lack of any effective remedy till recently. Leprosy control started with the use of chaulmoogra oil and for the last three decades, multi drug therapy (MDT has been our main tool against leprosy. In the last two decades, the reported global prevalence of active leprosy infection has dropped by almost 90 per cent by the combined efforts of the World Health Organization (WHO, local governments, health professionals, and non-governmental organizations (NGOs, however, a parallel drop in the incidence or new case detection rate (NCDR has not occurred. From 1994 through 2011, more than 100,000 new cases are being detected annually, of whom maximum case load is from India. There is need for research on tools for early diagnosis, short and effective treatment, and prevention of deformities and disabilities. Evaluating the role of immunotherapy and immunoprophylaxis will also lead us to better understanding of their mode of action. Further molecular analysis of Mycobacterium leprae genome may provide the requisite basis for all this. The current reality is that there is a need to sustain and provide quality leprosy services to all persons through general health services, including good referral system. All these provisions in the integrated health care approach will go a long way in further reducing the stigma. Efforts need to be made to reduce deformity through early detection, self care, physiotherapy and reconstructive surgery and developing sound surveillance systems. With all the remarkable achievements in the fight against leprosy, the stage is now set for the final assault. It is hoped that with the efforts of all the stake holders and strong political will, the disease will be eradicated in the near future.

    2013-01-01

    Full Text Available Leprosy (also known as Hansen’s disease is an infectious peripheral neurological disorder caused by Mycobacterium leprae that even today leaves millions of individuals worldwide with life-long disabilities. The specific mechanisms by which this bacterium induces nerve injury remain largely unknown, mainly owing to ethical and practical limitations in obtaining affected human nerve samples. In addition to humans, nine-banded armadillos (Dasypus novemcinctus are the only other natural host of M. leprae, and they develop a systemically disseminated disease with extensive neurological involvement. M. leprae is an obligate intracellular parasite that cannot be cultivated in vitro. Because of the heavy burdens of bacilli they harbor, nine-banded armadillos have become the organism of choice for propagating large quantities of M. leprae, and they are now advancing as models of leprosy pathogenesis and nerve damage. Although armadillos are exotic laboratory animals, the recently completed whole genome sequence for this animal is enabling researchers to undertake more sophisticated molecular studies and to develop armadillo-specific reagents. These advances will facilitate the use of armadillos in piloting new therapies and diagnostic regimens, and will provide new insights into the oldest known infectious neurodegenerative disorder.

In this case we report a 24 yr-old male patient who presented to our dermatology department with diagnosed paucibacillary leprosy by his local dermatologist, and confirmed by perineurovascular lymphocytic infiltrate in the histopathological exam. On physical examination we found new plaque lesions that were suggestive of morphea with alteration of sensitivity. A new biopsy was performed showing sclerotic superficial dermis with thickening of the collagen bundles in deep dermis and linear arrays lymphocytic infiltrate between the collagen bundles that confirm the diagnosis of morphea.

    Leprosy is clinically characterized by involvement of peripheral nerves and skin. The immunological profile of the individual defines the diversity of clinical manifestations, from skin disorders to systemic manifestations, especially the articulation ones, common in multibacillary forms, which may mimic collagen diseases and often posing diagnostic difficulties in endemic areas. This is a case report of asymmetric polyarthritis of small and large articulations associated with skin lesions which had been treated by a rheumatologist for 2 years with initial clinical diagnosis of rheumatoid arthritis, and later, with the appearance of skin lesions, of systemic lupus erythematosus.

    Full Text Available 50% of leprosy patients suffer from episodes of Type 1/ reversal reactions (RR and Type 2/ Erythema Nodosum Leprosum (ENL reactions which lead to morbidity and nerve damage. CD4+ subsets of Th17 cells and CD25+FOXP3+ regulatory T cells (Tregs have been shown to play a major role in disease associated immunopathology and in stable leprosy as reported by us and others. The aim of our study was to analyze their role in leprosy reactions.Quantitative reverse transcribed PCR (qPCR, flowcytometry and ELISA were used to respectively investigate gene expression, cell phenotypes and supernatant levels of cytokines in antigen stimulated PBMC cultures in patients with stable disease and those undergoing leprosy reactions. Both types of reactions are associated with significant increase of Th17 cells and associated cytokines IL-17A, IL-17F, IL-21, IL-23 and chemokines CCL20, CCL22 as compared to matching stable forms of leprosy. Concurrently patients in reactions show reduction in FOXP3+ Treg cells as well as reduction in TGF-β and increase in IL-6. Moreover, expression of many T cell markers, cytokines, chemokines and signaling factors were observed to be increased in RR as compared to ENL reaction patients.Patients with leprosy reactions show an imbalance in Th17 and Treg populations. The reduction in Treg suppressor activity is associated withhigherTh17cell activity. The combined effect of reduced TGF-β and enhanced IL-6, IL-21 cytokines influence the balance between Th17 or Treg cells in leprosy reactions as reported in the murine models and autoimmune diseases. The increase in Th17 cell associated cytokines may contribute to lesional inflammation.

  14. Job of the Bible: leprosy or scabies?

    Proposing a medical diagnosis a posteriori of a person who died a long time ago is not as impossible as it sounds if sufficient medical history is available.A whole book of the Bible is devoted to Job and his trials. The diagnosis of leprosy has been generally accepted by medieval commentators because the verses of the Book speak of ulcers disseminated over the skin, and also because leprosy is an exemplary sanction imposed by way of example by God to punish those who have committed a sin. In this paper, we have taken the different verses with a medical content from the Book of Job, and reconstructed the clinical picture as if the patient had turned up in the 21st century in order to see if the diagnosis of leprosy may be called into question, and to discuss the limits of the medico-historic approach. The clinical picture of the disease consists of deterioration in the general condition, with widespread pain, confusion, skin eruptions, bilious vomiting, and so on. Under these conditions, if Job did exist, and if the retrospective medical history is reliable, the most likely diagnosis is that of scabies rather than leprosy.

    Full Text Available Fifty fresh and untreated patients of leprosy constituted the study group. Fifty, age and sex matched healthy individuals formed the controls. Ridly and Jopling system of classification was used in the study. Majority i.e 21 cases were of BT group, 12 of BB, 7 of BL, 9 of LL and one case was of TT leprosy. The serum triglyceride level was lower than normal in TT, showed no alteration in BT or BB and was insignificantly increased in bL and LL patients. The total cholesterol was lowerthan normal in TT, showed no alteration in BT or BB and was insignificantly increased in Bland LL patients. The total cholesterol was lower than normal in TT, whereas in BT, BB, BL and LL groups the levels were statistically decreased. The HDL cholesterol was within normal range in TT, significantly decreased in BT and LL patients, showed no significant alteration in BB and was insignificantly decreased in BL group. The LDL cholesterol in TT was low but was not so low statistically when compared with the controls, whereas in BT, BB, BL and LL groups the levels were statistically decreased. The VLDL cholesterol was within normal range in TT and BT, was raised insignificantly in 3 of 12 cases of BB, was within normal range in BL and in LL leprosy it was raised in one out of 9 cases. In the absence of any derangement of liver function tests, it can be concluded that leprosy per se leads to alterations in lipid metabolism. However, no correlation could be established between the group/type of leprosy, bacterial indices and levels of different lipid fractions in the present study.

    Some of the leprosy patients facing problems in many aspects such as social, economic, cultural and national security. Both the debilitating effects and disfigurements of leprosy, the society tends to stigmatize negatively those suffering from leprosy. The impact of negative stigma on society causes depression and problems in workplace cause difficulty in patient’s daily life. Neuropathic pain disturbs the quality of life of leprosy patients which could become so severe and significant. The neuropathic pain will lower their productivity which later caused difficulties in finding a job. This study was an analytical observational study to identify the correlation between neuropathic pain and quality of life in Leprosy Hospital of Scanning in Medan Belawan. The result showed that there is a correlation between neuropathic pain and disruption of quality of life (p=0.017). In conclusion, the milder the neuropathic pain experienced by persons with leprosy, the less the quality of life will be disturbed.

    Full Text Available INTRODUCTION: This study aimed to evaluate the effect of the neural mobilization technique on electromyography function, disability degree, and pain in patients with leprosy. METHODS: A sample of 56 individuals with leprosy was randomized into an experimental group, composed of 29 individuals undergoing treatment with neural mobilization, and a control group of 27 individuals who underwent conventional treatment. In both groups, the lesions in the lower limbs were treated. In the treatment with neural mobilization, the procedure used was mobilization of the lumbosacral roots and sciatic nerve biased to the peroneal nerve that innervates the anterior tibial muscle, which was evaluated in the electromyography. RESULTS: Analysis of the electromyography function showed a significant increase (p<0.05 in the experimental group in both the right (Δ%=22.1, p=0.013 and the left anterior tibial muscles (Δ%=27.7, p=0.009, compared with the control group pre- and post-test. Analysis of the strength both in the movement of horizontal extension (Δ%right=11.7, p=0.003/Δ%left=27.4, p=0.002 and in the movement of back flexion (Δ%right=31.1; p=0.000/Δ%left=34.7, p=0.000 showed a significant increase (p<0.05 in both the right and the left segments when comparing the experimental group pre- and post-test. The experimental group showed a significant reduction (p=0.000 in pain perception and disability degree when the pre- and post-test were compared and when compared with the control group in the post-test. CONCLUSIONS: Leprosy patients undergoing the technique of neural mobilization had an improvement in electromyography function and muscle strength, reducing disability degree and pain.

    Pure neuritic variety of leprosy (PNL) presents as peripheral neuropathy with absent skin lesions and negative skin smears. Diagnosing PNL is an uphill task as most of these patients have nonspecific changes on nerve biopsy. In such circumstances, additional molecular diagnostic tools like polymerase chain reaction (PCR) has proven to be useful in diagnosing leprosy. The present study was planned to evaluate the role of PCR in nerve biopsy specimens of patients with PNL. Patients attending the neuromuscular clinic from January 2013 to June 2014 with mononeuropathy multiplex underwent detailed diagnostic evaluation to ascertain the cause of neuropathy. Patients where this evaluation failed to establish an etiology underwent a nerve biopsy. Nerve biopsy was done in 52 patients, of which 35 were diagnosed as pure neuritic leprosy. Definite leprosy with positive wade fite staining for lepra bacilli was seen in 13 patients and 22 biopsies revealed a probable leprosy without lepra bacilli being identified. PCR for M. leprae was positive in 22 patients (62%). 12 of the 13 cases with definite leprosy on histopathology were PCR positive while in the AFB negative group, PCR was positive in 10 cases. PCR had a sensitivity of 92.3%, specificity of 54.5%. The positive and negative predictive value of PCR was 54.5% and 92.3% respectively. PCR helps in diagnosing PNL in doubtful cases. A positive PCR increases the sensitivity of detection of M. leprae especially in cases of probable PNL group where AFB cannot be demonstrated on histopathology. Copyright © 2017 Elsevier B.V.

    2013-04-01

    Leprosy is a chronic infection of the skin and peripheral nerves caused by the bacterium Mycobacterium leprae, which causes peripheral insensitivity and disfigurements of the skin, limbs, and digits. Social stigma is a common consequence of leprosy and may differ according to level of physical disfigurement and geographic location. The objective of this study was to assess social stigma encountered by patients with leprosy in clinical settings located in rural Tanzania and urban USA and to compare the social stigma reported in these regions.   A total of 56 respondents were recruited from one leprosy inpatient facility in Shirati, Tanzania (n = 28), and one outpatient clinic in Los Angeles, USA (n = 28). Cross-sectional data were obtained from face-to-face interviews, which were conducted with respondents at each clinic location. Measures of perceived stigma were assessed in family relationship, vocational, social interaction, and interpersonal contexts.   Patients in Tanzania, as compared with those in the USA, reported significantly higher levels of stigma in family relationship and vocational contexts. Tanzanian patients also reported higher levels of stigma in social interaction and self-esteem contexts, but these differences were marginally significant and may reflect the small sample size.   Leprosy-related social stigma is a major problem in regions of both developed and developing countries; however, patients with leprosy in developing countries reported higher levels of stigma in four social contexts. A public health role in dermatology is discussed as an agent of early diagnosis, control, and education in order to reduce social stigma and promote social rehabilitation. © 2013 The International Society of Dermatology.

    Full Text Available Cell-mesate,d immune (CMI response to lepromin and dinitrochloro benzene (DNCB was evaluatt-d in 60 freshly detected leprosy cases. It was observed that 70%, ( 28 of 40 of the pa across tie leprosy spectrum except LL cases revealed delayed hypersensitivity to DNCB as -against 42.5% (1-7 of 40 to lepromin. DNCB test was found superior to lepromin test to measure CMI because of its simplicity and easy interpretation of skin reactivity. It detected CMI in 40% of BL cases who were lepromin negative. Grading of skin reactivity showed a program decrease in delayed hypersensitivity across the spectrum of leprosy from TT to LL. It can be concluded that there is no gross impairment of non-specific CMI in leprosy patients other than LL cases and this non-specific CMI depression correlates well with Ridley-Jopling clinical scale of leprosy.

    2012-06-01

    This study evaluated the degree of disability, pain levels, muscle strength, and electromyographic function (RMS) in individuals with leprosy. We assessed 29 individuals with leprosy showing common peroneal nerve damage and grade 1 or 2 disability who were referred for physiotherapeutic treatment, as well as a control group of 19 healthy participants without leprosy. All subjects underwent analyses of degree of disability, electromyographic tests, voluntary muscle force, and the Visual Analog Pain Scale. McNemar's test found higher levels of grade 2 of disability (Δ = 75.9%; p = 0.0001) among individuals with leprosy. The Mann-Whitney test showed greater pain levels (Δ = 5.0; p = 0.0001) in patients with leprosy who had less extension strength in the right and left extensor hallucis longus muscles (Δ = 1.28, p = 0.0001; Δ = 1.55, p = 0.0001, respectively) and dorsiflexion of the right and left feet (Δ = 1.24, p = 0.0001; Δ = 1.45, p = 0.0001, respectively) than control subjects. The Kruskal-Wallis test showed that the RMS score for dorsiflexion of the right (Δ = 181.66 m·s-2, p = 0.001) and left (Δ = 102.57m·s-2, p = 0.002) feet was lower in patients with leprosy than in control subjects, but intragroup comparisons showed no difference. Leprosy had a negative influence on all of the study variables, indicating the need for immediate physiotherapeutic intervention in individuals with leprosy. This investigation opens perspectives for future studies that analyze leprosy treatment with physical therapeutic intervention.

  16. Double-blind trial of the efficacy of pentoxifylline vs thalidomide for the treatment of type II reaction in leprosy

    Directory of Open Access Journals (Sweden)

    A.M. Sales

    2007-02-01

    Full Text Available Type II reaction in leprosy, or erythema nodosum leprosum (ENL, is often characterized by severe clinical symptoms together with nerve function impairment leading to permanent disabilities. Thalidomide has been shown to be a highly effective drug for the treatment of ENL. It is, however, contraindicated for women of childbearing age due to its teratogenicity. On the other hand, pentoxifylline, used to treat hypercoagulable states, is not teratogenic and, like thalidomide, can inhibit the synthesis of tumor necrosis factor-a and other cytokines. In the present randomized double-blind clinical study we compared the effectiveness of orally administered pentoxifylline vs thalidomide in treating type II reaction in 44 patients. Daily doses of 300 mg thalidomide or 1.2 g pentoxifylline were administered for 30 days to multibacillary leprosy patients undergoing type II reaction. Randomly chosen patients were included in the study before, during, and after specific multidrug therapy. Clinical evaluations were performed on the 1st, 7th, 14th, 21st, and 30th days of treatment and laboratory tests were carried out on the 1st and 30th days. As expected, overall, thalidomide proved to be more effective in the treatment of type II leprosy reaction. Nevertheless, continuous treatment with pentoxifylline was effective in relieving the clinical signs of ENL, especially limb edema and systemic symptoms, in 62.5% of the patients.

  17. ASSESSMENT OF PATIENTS’ PERCEPTIONS TOWARDS THE DIAGNOSIS OF LEPROSY

    Directory of Open Access Journals (Sweden)

    S. V. Jezus

    2018-02-01

    Full Text Available Leprosy is a contagious, long-term infection, which manifests dermatological and neurological symptoms and signs, being considered an endemic, widespread disease, regarded as a serious health problem in Brazil. Early diagnosis of leprosy and its proper treatment prevents disease from progressing, avoiding physical disabilities, which are frequent as the infection evolves, and constitute a major cause of stigma, leading the patient to social isolation. This study aimed to verify the patient's perceptions regarding Hansen's disease diagnosis, seeking to contribute to the prevention of physical disabilities. It was carried out in Sinop in the State of Mato Grosso, being classified as a qualitative research approach. Patients diagnosed with leprosy, enrolled for annual treatment in Nações Basic Health Unity (Unidade de Saúde Básica Nações, took part in the research. Data was collected using semi-structured interviews, and the results were analyzed in categories, these being, the implications on the patients’ self-esteem after diagnosis of leprosy; patients’ perceptions of treatment and changes in socioeconomic status after leprosy. It is worth noting that leprosy as a public health issue does not restrict to the immense amount of cases and its potential to cause physical disability, which interferes in the psychosocial context, should be taken into consideration. It is valid to point out that leprosy affects several aspects of the pacient’s life, including their physical, mental and social well-being, requiring a holistic and humane nursing care.

  18. The leprosy asylum in India: 1886-1947.

    Science.gov (United States)

    Robertson, Jo

    2009-10-01

    Writing against a historical practice that situates the leprosy asylum exclusively within prison-like institutions, this article seeks to show the variation in leprosy asylums, the contingencies of their evolution, and the complexity of their designs, by devoting attention to the characteristics of the leprosy asylum in India from 1886 to 1947, in particular to the model agricultural colony. Drawing upon the travel narratives of Wellesley Bailey, the founder of the Mission to Lepers in India, for three separate periods in 1886, 1890-91, and 1895-96, it argues that leprosy asylums were formed in response to a complex conjunction of impulses: missionary, medical, and political. At the center of these endeavors was the provision of shelter for persons with leprosy that accorded with principles of good stewardship and took the form of judicious use of donations provided by benefactors. As the Mission to Lepers began to bring about improvements and restructuring to asylums, pleasant surroundings, shady trees, sound accommodation, and good ventilation became desirable conditions that would confer physical and psychological benefits on those living there. At the same time, the architecture of the asylum responded to economic imperatives, in addition to religious and medical aspirations, and asylums moved towards the regeneration of a labor force. Leprosy-affected people were increasingly employed in occupations that contributed to their sustenance and self-sufficiency, symbolically reincorporating the body damaged by leprosy into the economic world of productive relations.

  19. Pride and prejudice--identity and stigma in leprosy work.

    Science.gov (United States)

    Harris, Kristine

    2011-06-01

    This article sets out to expand the way stigma, and those affected by it, are understood within leprosy discourse and to apply these insights to the analysis of the experiences of leprosy workers. The term stigma is often used simply as shorthand for 'negative social experience'. However, to reduce the negative aspects of complex everyday life experiences to a single word is often overly simplistic and can serve to objectify, rather than illuminate, the experiences of those affected. This article argues that in order to understand the lived experience of stigma we must come to understand stigma as an ongoing, dialectical social process and develop an approach to stigma that analytically separates stigma from its negative social consequences. The article applies these insights to data collected during 14 months of fieldwork with front-line leprosy workers in India, which suggests that falling leprosy prevalence rates and a rapidly changing policy landscape have led to leprosy workers feeling marginalised and stigmatised within their own organisation. The article argues that, rather than seeing stigma merely as a negative process in which leprosy workers are passive victims, we must recognise that stigma also plays a key role in the creation and maintenance of leprosy workers' identity and is utilised as a strategic tool in the struggle for influence between different groups within the organisation. Finally, the article argues for the benefit of expanding our understanding of stigma across public health and of applying these insights to designing future interventions.

  20. Can social marketing approaches change community attitudes towards leprosy?

    Science.gov (United States)

    Brown, Wendy

    2006-06-01

    This essay explores how the concept of social marketing can be employed to change attitudes towards leprosy. Firstly, the concept of social marketing is discussed, then the attitudes that people have about leprosy, the stigma that people with leprosy and their families may face, and the detrimental effects that this can have on their lives. The effect of knowledge and education on attitudes towards leprosy is discussed, as this can be a key component of social marketing campaigns. Various methods of social marketing used to change attitudes and reduce stigma are examined, such as mass media campaigns, school based education, methods which involve community leaders, and the integration and improvement of leprosy services. Principles of social marketing which can lead to the success of campaigns such as incorporating local beliefs are emphasized. The success of the social marketing campaign in Sri Lanka is described, which aimed to remove the fear of leprosy, and to encourage patients to seek and comply with treatment. Finally, it is argued that social marketing, used correctly, can be highly effective at changing community attitudes towards leprosy, reducing stigma and improving the lives of patients, who become able to seek treatment sooner as they lose their fear of stigmatization.

    Leprosy or Hansen disease is caused by an infection of Mycobacterium leprae. The large number of undetected cases (2000-2012 years 4 mln people) remains a threat to the elimination of leprosy. Leprosy is an unheard in Poland and generally is considered a condition so "exotic" that it is not worth to spend more attention to it. Forgotten disease in developed countries still thrives in an environment of poor and uneducated. Regardless of the conclusion that in the 21st century none infectious disease should not be treated as a disease on the designated regions of the world, other than our own, it should be recalled that the M. leprae was discovered in Europe, where for many years there were leprosaria and still infectious hospitals in Great Brittan, France or Spain get patients suspected of leprosy. The mobility of the inhabitants of the globe caused by wars, ethnic conflicts or a simple tourism causes that any infectious disease can not be treated as solely limited to distant us regions. The best proof of this were the viral diseases, formerly found in only in Asia or Africa, and currently transmitted to Europe [1]. At any moment, we can stand up against the problem of diagnostics of humans toward leprosy. Many medical reports indicate that leprosy as a disease with many symptoms encountered difficulties in its diagnosis. Only the experience of medical professionals and good microbiological diagnosis may speed up the diagnosis of leprosy.

    On the basis of correlative data on the global distribution of leprosy, its bacteria metabolizing fossil fuels (FF), and the FF themselves, the origin of leprosy in the world as a whole, and in the leprosy-free countries, in particular, as indigenous cases, appeared to be primarily due to a soil-to-man, and secondarily due to a man-to-man infection. These findings helped to elucidate similar problems of animal leprosies and nocardial diseases.

    Full Text Available Resistance to multidrug therapy (MDT is one of the complications in the treatment of Hansen’s disease/Morbus Hansen (MH. There are two types of resistancy, which are primary and secondary. MDT-multibacillary (MB resistance must be suspected when no clinical improvement and the acid-fast bacilli (AFB index is not reduced after 12 months of therapy. A 28-year-old woman with paresthesia on her face, arms and legs since 2.5 years ago, accompanied by thickening of the right posterior tibial nerve. The AFB examination showed a bacteriological index (BI of 15/6 and morphological index (MI of 0.50%. The second case, a 42-year-old man came with paresthetic lesions on his face, chest, back, both arms and legs since 2 years ago, accompanied by thickening of ulnar and lateral peroneal nerve. The BI was 12/5 and the MI was 0.40%. Both patients were diagnosed with borderline lepromatous type of MH and received MDT-MB for 12 months. Diagnosis of suspected resistance was established because no clinical improvement or any significant decrease of AFB index after completing the MDT treatment. The patients had secondary resistance after polymerase chain reaction evaluation showed that they were still rifampicin-sensitive. There was clinical improvement and significant decrease in FAB index after the patients continued the MDT-MB treatment with 600 mg additional rifampicin. The diagnosis of bacterial resistance should be made based on clinical evaluation before completion of treatment. Based on the two case reports, the resistance suspected may be secondary. Treatment using additional regimen can be initiated once the resistance has been proven.

    Full Text Available BACKGROUND: This study aimed to evaluate the risk factors associated with developing leprosy among the contacts of newly-diagnosed leprosy patients. METHODOLOGY/PRINCIPAL FINDINGS: A total of 6,158 contacts and 1,201 leprosy patients of the cohort who were diagnosed and treated at the Leprosy Laboratory of Fiocruz from 1987 to 2007 were included. The contact variables analyzed were sex; age; educational and income levels; blood relationship, if any, to the index case; household or non-household relationship; length of time of close association with the index case; receipt of bacillus Calmette-Guérin (BGG vaccine and presence of BCG scar. Index cases variables included sex, age, educational level, family size, bacillary load, and disability grade. Multilevel logistic regression with random intercept was applied. Among the co-prevalent cases, the leprosy-related variables that remained associated with leprosy included type of household contact, [odds ratio (OR = 1.33, 95% confidence interval (CI: 1.02, 1.73] and consanguinity with the index case, (OR = 1.89, 95% CI: 1.42-2.51. With respect to the index case variables, the factors associated with leprosy among contacts included up to 4 years of schooling and 4 to 10 years of schooling (OR = 2.72, 95% CI: 1.54-4.79 and 2.40, 95% CI: 1.30-4.42, respectively and bacillary load, which increased the chance of leprosy among multibacillary contacts for those with a bacillary index of one to three and greater than three (OR = 1.79, 95% CI: 1.19-2.17 and OR: 4.07-95% CI: 2.73, 6.09, respectively. Among incident cases, household exposure was associated with leprosy (OR = 1.96, 95% CI: 1.29-2.98, compared with non-household exposure. Among the index case risk factors, an elevated bacillary load was the only variable associated with leprosy in the contacts. CONCLUSIONS/SIGNIFICANCE: Biological and social factors appear to be associated with leprosy among co-prevalent cases, whereas the factors related to the

    We present a patient with leprosy who developed Hodgkin's disease of the nodular sclerosing type. There are two previous reports describing the combination of leprosy and Hodgkin's disease in a single patient [3, 9]. Hodgkin's disease was diagnosed 14 months after the complete disappearance of mycobacterium leprae from the skin lesions, under treatment with DDS (diamino-diphenyl-sulfone). Hodgkin's disease was treated by irradiation and chemotherapy. Obstructive jaundice developed which resolved under treatment by irradiation of the hilar area of the liver, chemotherapy and hormones. During two years of immuno-suppressive therapy, without DDS, no exacerbation of the leprosy occurred.

    Full Text Available Background: Leprosy a chronic infectious affliction, is a communicable disease that posses a risk of permanent and progressive disability. The associated visible deformities and disabilities have contributed to the stigma and discrimination experienced by leprosy patients, even among those who have been cured. Aims and Objectives: 1 To assess the knowledge, attitude and belief about leprosy in leprosy patients compared with community members. 2 To find the perceived stigma among leprosy patients. 3. To evaluate the quality of life in leprosy patients as compared to community members using WHO Quality of Life assessment questionaire (WHOQOL- BREF. Materials and Methods: A cross sectional study was conducted at Leprosy Rehabilitation Centre, Shantivan, Nere in Panvel Taluka, district Raigad from October - December 2009. A pre-designed and pre-structured questionaire was used to evaluate knowledge, attitude and perceived stigma among leprosy patients and community members. WHO Quality of life questionaire (WHOQOL-BREF was used to assess quality of life in leprosy patients and controls. Data analysis was done with the help of SPSS package. Result: Among the cases and control, 43.13% of cases were aware that leprosy is an infectious disease compared to 20.69% of control. 68.62% of cases had knowledge of hypopigmented patches being a symptom of leprosy compared to the 25.86% in control. There was overall high level of awareness about disease, symptoms, transmission and curability in leprosy patients as compared to control. Among control group, 43.10% of population said that they would not like food to be served by leprosy patients as compared to 13.73% in study group. It was seen that the discrimination was much higher in female leprosy patients as compared to male leprosy patients. The mean quality of life scores for cases was significantly lower than those for control group in physical and psychological domain but not in the social relationship and

    Jose Luiz Fernandes Vieira

    Full Text Available The objective of this work was to determine the methemoglobinemia and correlate with dapsone levels in multibacillary leprosy patients under leprosy multi-drug therapy. Thirty patients with laboratory and clinical diagnosis of multibacillary leprosy were enrolled. Dapsone was analyzed by high performance liquid chromatography and methemoglobinemia by spectrophotometry. The mean dapsone concentrations in male was 1.42 g/mL and in female was 2.42 g/mL. The mean methemoglobin levels in male was 3.09 µg/mL; 191%, and in female was 2.84 ± 1.67%. No correlations were seen between dapsone levels and methemoglobin in male and female patients. Our results demonstrated that the dosage of dapsone in leprosy treatment does not promote a significant methemoglobinemia.

    Directory of Open Access Journals (Sweden)

    Geraldo Bezerra da Silva Junior

    2015-02-01

    Full Text Available Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are the so called reactional states, in which the immune system reacts against the bacilli, exacerbating the clinical manifestations. Different renal lesions have been described in leprosy, including acute and chronic glomerulonephritis, interstitial nephritis, secondary amyloidosis and pyelonephritis. The exact mechanism that leads to glomerulonephritis in leprosy is not completely understood. Leprosy treatment includes rifampicin, dapsone and clofazimine. Prednisone and non-steroidal anti-inflammatory drugs may be used to control acute immunological episodes.

    After tuberculosis, leprosy (Mycobacterium leprae) and Buruli ulcer (M. ulcerans infection) are the second and third most common mycobacterial infections in humankind, respectively. Recent advances in both diseases are summarized. Leprosy remains a public health problem in some countries, and new case detections indicate active transmission. Newly identified M. lepromatosis, closely related to M. leprae, may cause disseminated leprosy in some regions. In genome-wide screening in China, leprosy susceptibility associates with polymorphisms in seven genes, many involved with innate immunity. World Health Organization multiple drug therapy administered for 1 or 2 years effectively arrests disseminated leprosy but disability remains a public health concern. Relapse is infrequent, often associated with higher pretreatment M. leprae burdens. M. ulcerans, a re-emerging environmental organism, arose from M. marinum and acquired a virulence plasmid coding for mycolactone, a necrotizing, immunosuppressive toxin. Geographically, there are multiple strains of M. ulcerans, with variable pathogenicity and immunogenicity. Molecular epidemiology is describing M. ulcerans evolution and genotypic variants. First-line therapy for Buruli ulcer is rifampin + streptomycin, sometimes with surgery, but improved regimens are needed. Leprosy and Buruli ulcer are important infections with significant public health implications. Modern research is providing new insights into molecular epidemiology and pathogenesis, boding well for improved control strategies.

    In Central America, few cases of leprosy have been reported, but the disease may be unrecognized. Diagnosis is based on clinical criteria and histology. Preliminary field work in Nicaragua and Honduras found patients, including many children, with skin lesions clinically suggestive of atypical cutaneous leishmaniasis or indeterminate leprosy. Histology could not distinguish these diseases although acid-fast organisms were visible in a few biopsies. Lesions healed after standard antimicrobial therapy for leprosy. In the present study, patients, family members, and other community members were skin-tested and provided nasal swabs and blood samples. Biopsies were taken from a subgroup of patients with clinical signs of infection. Two laboratories analyzed samples, using local in-house techniques. Mycobacterium leprae , Leishmania spp. and Leishmania infantum were detected using polymerase chain reactions. Mycobacterium leprae DNA was detected in blood samples and nasal swabs, including some cases where leprosy was not clinically suspected. Leishmania spp. were also detected in blood and nasal swabs. Most biopsies contained Leishmania DNA and coinfection of Leishmania spp. with M. leprae occurred in 33% of cases. Mycobacterium leprae DNA was also detected and sequenced from Nicaraguan and Honduran environmental samples. In conclusion, leprosy and leishmaniasis are present in both regions, and leprosy appears to be widespread. The nature of any relationship between these two pathogens and the epidemiology of these infections need to be elucidated.

    Leprosy is caused by the Mycobacterium leprae bacillus. Pockets of high endemicity remain in a number of countries including Sri Lanka, in spite of the fact that elimination has been achieved at the national level. In 2012, in a village in the Puttlam district, dermatologists reported an increase in individuals with leprosy. This village had been established in the 1990s for people displaced from Northern Sri Lanka during a civil war. A comprehensive household survey was conducted by district health officials from June to July 2012, and all household members present during the survey period were examined for leprosy lesions. Patients with suspected leprosy were referred to a dermatology clinic for clinical or pathological confirmation. The prevalence of leprosy was high (511 per 10 000 population). Household contact with another patient with leprosy increased the risk of leprosy (odds ratio = 6.69; P < .001). Continued vigilance is needed to keep leprosy at bay in high-risk communities.

    The study aims at describing the achievements and challenges of Leprosy control in Kaduna State using appropriate indicators. The study was a five year (2004-2008) retrospective review of the Leprosy records and annual reports of all the twenty three LGAs in Kaduna State. Various Leprosy indicators were calculated and presented in different graphic presentations. Focus group discussions were organised with the aim of identifying current challenges of Leprosy control in the State. There was a decline in the new Leprosy cases detected annually from 226 cases in 2004 to 140 cases in 2008. The prevalence rate ranged between 0.3-0.4 per 10,000 population within the five year period. The proportion of children among new cases dropped from 12% in 2004 to 5% in 2007 and increased to 9% in 2008. Grade 2 disability among new cases was very high (between 21%-27%) within the same period. Leprosy elimination target has been achieved in Kaduna State, but new cases with high proportion of children and WHO grade 2 disability were still been reported.

    Leprosy is a disease that causes not only physical problems, but also mental and social problems. In the post integration era, every health care professional needs to understand about leprosy, to be able to diagnose and treat them. Physiotherapy students, in their usual syllabus, have minimal exposure to leprosy, in spite of the fact that they have a major role in preventing impairments and disabilities caused by leprosy, as well as treating such impairments. In order to educate physiotherapy students on leprosy, a one-week intensive training course was organised. This study was done to assess if the intensive training to physiotherapy students resulted in increase in their knowledge on leprosy and change their attitude positively. A batch consisting of 42 physiotherapy students went through the one-week training programme. The improvement in knowledge and attitude were assessed through a pre-test and a post-test design. Results showed that there was significant improvement in knowledge (53.05%) and brought positive change in attitude (75.0%). Such training programmes are recommended for all physiotherapy students.

    Full Text Available Background. Leprosy reactions are acute inflammatory episodes that occur mainly in the multibacillary forms of the disease. The reactions are classified as type 1 (reverse reaction or type 2 (erythema nodosum leprosum. Leprosy-associated oxidative stress has been widely demonstrated. Several recent studies have shown uric acid (UA to have antioxidative effects under pathologic conditions. The objective of this study was to assess serum levels of UA in patients with leprosy reactions, with the aim of monitoring their levels before and after treatment, compared with levels in leprosy patients without reactions. Methods. The study included patients aged 18–69 years assisted at a leprosy treatment reference center in the Central Region of Brazil. Patients who were pregnant; were using immunosuppressant drugs or immunobiologicals; or had an autoimmune disease, human immunodeficiency virus infection, acquired immune deficiency syndrome, or tuberculosis were excluded. Upon recruitment, all individuals were clinically assessed for skin lesions and neural or systemic impairment. Some patients had already completed treatment for leprosy, while others were still undergoing treatment or had initiated treatment after being admitted. The treatment of the reactional episode was started only after the initial evaluation. Laboratory assessments were performed upon admission (baseline and at approximately 30 and 60 days (time points 1 and 2, respectively. Results. A total of 123 leprosy patients were recruited between June 2012 and June 2015; among them, 56, 42, and 25 presented with type 1, type 2, and no reactions, respectively. Serum UA levels were significantly reduced in patients with type 2 leprosy reactions compared with patients in the control group and remained lower in the two subsequent assessments, after initiation of anti-reaction treatments, with similar values to those recorded before the treatment.

    Full Text Available It has been stated, in different types of texts, that there are only twelve pairs of cranial nerves. Such texts exclude the existence of another cranial pair, the terminal nerve or even cranial zero. This paper considers the mentioned nerve like a cranial pair, specifying both its connections and its functional role in the migration of liberating neurons of the gonadotropic hormone (Gn RH. In this paper is also stated the hypothesis of the phylogenetic existence of a cerebral sector and a common nerve that integrates the terminal nerve with the olfactory nerves and the vomeronasals nerves which seem to carry out the odors detection function as well as in the food search, pheromone detection and nasal vascular regulation.

    ABSTRACT The genetic inheritance of resistance to leprosis, the most important viral disease of citrus in Brazil, was characterized through the phenotypic assessment of 143 hybrids resulting from crosses between tangor 'Murcott' (Citrus sinensis x C. reticulata) and sweet orange 'Pêra' (C. sinensis), considered to be resistant and susceptible to the disease, respectively. All plants were grafted onto Rangpur lime (C. limonia) and inoculated with Citrus leprosis virus, cytoplasmic type through the infestation with viruliferous mites, Brevipalpus phoenicis. The experiments were arranged in a completely randomized block design with 10 replicates. Incidence and severity of the disease in leaves and stems as well as plant growth parameters (plant height and stem diameter) were recorded for 3 years after the infestation with the viruliferous mites. The average values of all variables were analyzed using principal component analysis, discriminant factorial analysis, estimation of the clonal repeatability coefficients, and frequency of the distributions of the average values for each measured variable. The principal component analysis resulted in the identification of at least two groups with resistance and susceptibility to leprosis, respectively. About 99% of all hybrids were correctly classified according to the discriminant factorial analysis. The broad-sense heritability coefficients for characteristics associated with incidence and severity of leprosis ranged from 0.88 to 0.96. The data suggest that the inheritance of resistance to leprosis may be controlled by only a few genes.

    Full Text Available Abstract Leprosy remains a public health problem in developing countries. Among communicable diseases, it is one of the leading causes of permanent disability. Brazil had not reached the goal of reducing cases to less than 1 per 10,000 population. This study aimed to analyze the spatial distribution of leprosy cases in Brazil, using a literature review. The search strategy included the LILACS and MEDLINE databases with no language or period restriction. Ecological studies with spatial data analysis were considered as a criterion for the inclusion. We found 38 studies for review after the selection criteria. Among the epidemiological indicators of the disease, the most common was the new case detection rate. Several articles have explored the association between spatial distribution of leprosy and socioeconomic, demographic, and environmental factors. The most common unit of analysis was the municipality. The spatial distribution methods mostly used were: empirical Bayesian method, autocorrelation (Moran’s I index and Kernel estimates. The distribution of leprosy was very heterogeneous, independent of the unit of analysis. There was a decrease in the rate of detection and among under-15-year-olds, but some regions maintained high endemicity during the study period. The distribution and risk of illness were directly related to living conditions of the population. Improved access to health services was associated with increased detection rate in some regions. Spatial analysis seems to be a very useful tool to study leprosy and to guide interventions and surveillance.

    The results of bacteriological and histological examinations of the organs of mice infected in the footpad with human leprosy bacilli by the Shepard method are summarized. The periods of observation ranged from a few days to 2 years. The disease developed in mice as a chronic infection with a lengthy “incubation” period of 3-4 months or more without symptoms. Usually about 2 years after inoculation, or in some cases after a shorter interval, the disease became generalized. Different types of tissue reaction occurred: simple inflammatory infiltration, tuberculoid granuloma, and leproma-like granuloma, similar to the clinical types of leprosy in man. When the infection became general, cells resembling lepra cells formed in the internal organs and at the site of infection. These cells contained massive intracellular aggregations of mycobacteria and compact globi with lipids and a vacuolized protoplasm, similar in origin and morphology to the lepra cells in human lesions. Changes were found in the neuroreceptor apparatus of the skin of the mice, with groups of leprosy bacilli in the endoneurium, the Schwann cells, and the perineural spaces. The length of the experiments and the histological examination of material from the sacrificed mice at different stages of the infective process revealed biological parallels with human leprosy and threw light on a number of aspects of the pathogenesis of leprosy.

PURPOSES: To find out the pattern of psychiatric morbidity in leprosy patients and the relationship of various factors with the morbidity. METHODS: Ninty patients attending leprosy clinic were randomly chosen for the study group alongwith 40 patients suffering from acute skin problem other than leprosy as control group. The socio-demographic data were recorded in semi-structural proforma; all patients were given Goldbery Health Questioneaire (GHQ. Patients having GHQ score> 2 was assessed by Disability Assessent Questionaire (DAQ. The psychiatric diagnoses was made according to ICD-10 by W ho0 and physical deformity by W ho 0 Disability Scale. FINDINGS: The mean GHQ score of the study grant was 3.44 and that of control group was 1.62. The mean DAQ score was 45.13. Psychiatric disorder was seen in 44.4% and 7.5% of study group and control group respectively. The psychiatric illness was generalised anoxidy disorder (GAD (27.8%. CONCLUSIONS: Leprosis highly associated with psychiatric mobidity. LIMITATIONS: The findings can not be generalised due to small sample size and clinic-based data.

    The objective of this cross-sectional comparative study was to find the effects of environment and education on knowledge and attitude of nursing students towards leprosy. Data were collected, using a pretested questionnaire, from the first year and third year students of a School of Nursing attached to a leprosy specialty hospital and also from a comparable School of Nursing attached to a general hospital. The results showed that trainees acquired more knowledge on leprosy during training in both schools of nursing. However, those trained in leprosy hospital environment had higher knowledge and attitude scores than those trained in general hospital environment. The attitude of the trainees attached to leprosy hospital was favourable even before they had formal training in leprosy. Those trained in the general hospital showed more favourable attitude after training compared to before training. School of Nursing attached to leprosy hospital provided an atmosphere conducive to learning and understanding more about leprosy. The trainees retained what was learnt because of regular association with patients affected by leprosy. For employment in hospital or community based services or research related to leprosy, nurses trained in a leprosy hospital would have added value of knowledge and attitude.

    Leprosy is among the world's oldest and most dreaded diseases and it has been synonymous with stigma and discrimination due to the hideous deformities it produced, mystery around its aetiology and transmission and lack of any effective remedy till recently. Leprosy control started with the use of chaulmoogra oil and for the last three decades, multi drug therapy (MDT) has been our main tool against leprosy. In the last two decades, the reported global prevalence of active leprosy infection has dropped by almost 90 per cent by the combined efforts of the World Health Organization (WHO), local governments, health professionals, and non-governmental organizations (NGOs), however, a parallel drop in the incidence or new case detection rate (NCDR) has not occurred. From 1994 through 2011, more than 100,000 new cases are being detected annually, of whom maximum case load is from India. There is need for research on tools for early diagnosis, short and effective treatment, and prevention of deformities and disabilities. Evaluating the role of immunotherapy and immunoprophylaxis will also lead us to better understanding of their mode of action. Further molecular analysis of Mycobacterium leprae genome may provide the requisite basis for all this. The current reality is that there is a need to sustain and provide quality leprosy services to all persons through general health services, including good referral system. All these provisions in the integrated health care approach will go a long way in further reducing the stigma. Efforts need to be made to reduce deformity through early detection, self care, physiotherapy and reconstructive surgery and developing sound surveillance systems. With all the remarkable achievements in the fight against leprosy, the stage is now set for the final assault. It is hoped that with the efforts of all the stake holders and strong political will, the disease will be eradicated in the near future.

    Leprosy, which in particular affects poor people of developing countries, was also a challenge for social and charitable activities. This was possible due to the engagement of "great community workers," people who devoted their professional and family life, passions, and their own material goods to conduct socio-medical activities among leprosy affected persons. This contribution discusses the work of the lepro-activists of international fame, Albert Schweitzer and Mother Teresa of Calcutta, as well as those who are less well known, Wanda Maria Błeńska and Marian Żelazek.

    Full Text Available La inmunidad protectora contra Mycobacterium leprae requiere IFN-g. Los pacientes con lepra tuberculoide producen localmente citoquinas Th1, mientras que los pacientes lepromatosos producen citoquinas Th2. La molécula linfocitaria activadora de señales (SLAM y la proteína asociada a SLAM (SAP participan en la diferenciación celular que conduce a producción de patrones específicos de citoquinas. A fin de investigar la vía SLAM/SAP en la infección por M. leprae, determinamos expresión de ARN mensajero (ARNm de SAP, IFN-g y SLAM en pacientes con lepra. Observamos que la expresión de SLAM correlacionó en forma directa con la expresión de IFN-g, mientras que la expresión de SAP correlacionó inversamente con la expresión de ambas proteínas. Así, nuestros resultados indican que SAP interferiría con las respuestas de citoquinas Th1 mientras que SLAM contribuiría con la respuesta Th1 en lepra, señalando a la vía SLAM/SAP como potencial blanco modulador de citoquinas en enfermedades con respuestas Th2 disfuncionales.Tuberculoid leprosy patients locally produce Th1 cytokines, while lepromatous patients produce Th2 cytokines. Signaling lymphocytic activation molecule (SLAM and the SLAM-associated protein (SAP participate in the differentiation process that leads to the production of specific patterns of cytokines by activated T cells. To investigate the SLAM/SAP pathway in M. leprae infection, we determined the expression of SAP, IFN-g and SLAM RNA messenger in leprosy patients. We found a direct correlation of SLAM expression with IFN-g expression, whereas the expression of SAP was inversely correlated with the expression of both SLAM and IFN-g. Therefore, our data indicate that SAP might interfere with Th1 cytokine responses while SLAM expression may contribute to Th1 responses in leprosy. This study further suggests that the SLAM/SAP pathway might be a focal point for therapeutic modulation of T cell cytokine responses in diseases

    Leprosy is a chronic infectious disease caused by bacteria of leprosy (Mycobacterium leprae). Leprosy has become an important thing in Indonesia because its morbidity is quite high. Based on WHO data in 2014, in 2012 Indonesia has the highest number of new leprosy patients after India and Brazil with a contribution of 18.994 people (8.7% of the world). This number makes Indonesia automatically placed as the country with the highest number of leprosy morbidity of ASEAN countries. The province that most contributes to the number of leprosy patients in Indonesia is East Java. There are two kind of leprosy. They consist of pausibacillary and multibacillary. The morbidity of multibacillary leprosy is higher than pausibacillary leprosy. This paper will discuss modeling both of the number of multibacillary and pausibacillary leprosy patients as responses variables. These responses are count variables, so modeling will be conducted by using bivariate poisson regression method. Unit experiment used is in East Java, and predictors involved are: environment, demography, and poverty. The model uses data in 2012, and the result indicates that all predictors influence significantly.

    Mycobacterium leprae is the only pathogenic bacteria able to infect peripheral nerves. Neural impairment results in a set of sensitive, motor and autonomic disturbances, with ulcers originating primarily on the hands and feet. The study objectives were to analyze the clinic-epidemiological characteristics of patients attended at one specialized dressing service from a leprosy-endemic region of the Brazilian Amazon and to evaluate the effect of low level laser therapy (LLLT) on wound healing of these patients. Clinic-epidemiological evaluation of patients with leprosy sequelae was performed at the reference unit in sanitary dermatology of the state of Pará in Brazil. We conducted anamnesis, identification of the regions affected by the lesions and measurement of ulcer depth and surface area. After that, we performed a randomized clinical trial. Fifty-one patients with ulcers related to leprosy were evaluated, twenty-five of them were randomly assigned to a low level laser therapy group or a control group. Patients were treated 3 times per week for 12 weeks. Outcome measures were ulcer surface area, ulcer depth and the pressure ulcer scale for healing score (PUSH). Ninety-seven ulcers were identified, with a mean (SD) duration of 97.6 (111.7) months, surface area of 7.3 (11.5) cm2, and depth of 6.0 (6.2) mm. Statistical analysis of the data determined that there were no significant differences in the variables analyzed before and after treatment with low level laser therapy. Ulcers in patients with leprosy remain a major source of economic and social losses, even many years after they have been cured of M. leprae infection. Our results indicate that it is necessary to develop new and more effective therapeutic tools, as low level laser therapy did not demonstrate any additional benefits to ulcer healing with the parameters used in this study. The trial was registered at ClinicalTrials.gov as NCT00860717.

  2. Are human peripheral nerves sensitive to X-ray imaging?

    Directory of Open Access Journals (Sweden)

    Jonas Francisco Scopel

    Full Text Available Diagnostic imaging techniques play an important role in assessing the exact location, cause, and extent of a nerve lesion, thus allowing clinicians to diagnose and manage more effectively a variety of pathological conditions, such as entrapment syndromes, traumatic injuries, and space-occupying lesions. Ultrasound and nuclear magnetic resonance imaging are becoming useful methods for this purpose, but they still lack spatial resolution. In this regard, recent phase contrast x-ray imaging experiments of peripheral nerve allowed the visualization of each nerve fiber surrounded by its myelin sheath as clearly as optical microscopy. In the present study, we attempted to produce high-resolution x-ray phase contrast images of a human sciatic nerve by using synchrotron radiation propagation-based imaging. The images showed high contrast and high spatial resolution, allowing clear identification of each fascicle structure and surrounding connective tissue. The outstanding result is the detection of such structures by phase contrast x-ray tomography of a thick human sciatic nerve section. This may further enable the identification of diverse pathological patterns, such as Wallerian degeneration, hypertrophic neuropathy, inflammatory infiltration, leprosy neuropathy and amyloid deposits. To the best of our knowledge, this is the first successful phase contrast x-ray imaging experiment of a human peripheral nerve sample. Our long-term goal is to develop peripheral nerve imaging methods that could supersede biopsy procedures.

    Full Text Available BackgroundNotwithstanding its beneficial immunoprophylactic outcomes regarding leprosy and childhood TB, BCG vaccination may cause adverse events, particularly of the skin. However, this local hyper-immune reactivity cannot be predicted before vaccination, nor is its association with protection against leprosy known. In this study we investigated the occurrence of adverse events after BCG (revaccination in contacts of leprosy patients and analyzed whether the concomitant systemic anti-mycobacterial immunity was associated with these skin manifestations.MethodsWithin a randomized controlled BCG vaccination trial in Bangladesh, 14,828 contacts of newly diagnosed leprosy patients received BCG vaccination between 2012 and 2017 and were examined for adverse events 8 to 12 weeks post-vaccination. From a selection of vaccinated contacts, venous blood was obtained at follow-up examination and stimulated with Mycobacterium leprae (M. leprae antigens in overnight whole-blood assays (WBA. M. leprae phenolic glycolipid-I-specific antibodies and 32 cytokines were determined in WBAs of 13 individuals with and 13 individuals without adverse events after vaccination.ResultsOut of the 14,828 contacts who received BCG vaccination, 50 (0.34% presented with adverse events, mainly (80% consisting of skin ulcers. Based on the presence of BCG scars, 30 of these contacts (60% had received BCG in this study as a booster vaccination. Similar to the pathological T-cell immunity observed for tuberculoid leprosy patients, contacts with adverse events at the site of BCG vaccination showed elevated IFN-γ levels in response to M. leprae-specific proteins in WBA. However, decreased levels of sCD40L in serum and GRO (CXCL1 in response to M. leprae simultaneously indicated less T-cell regulation in these individuals, potentially causing uncontrolled T-cell immunity damaging the skin.ConclusionSkin complications after BCG vaccination present surrogate markers for protective

    Full Text Available OBJECTIVE: This study aimed to determine the frequency of coinfections in leprosy patients and whether there is a relationship between the presence of coinfections and the development of leprosy reactional episodes. METHOD: A cross-sectional study based on an analysis of the medical records of the patients who were treated at the Leprosy Clinics of the Ribeirão Preto Medical School, University of São Paulo, was conducted from 2000 to 2010. Information was recorded regarding the age, sex, clinical status, WHO classification, treatment, presence of reactions and coinfections. Focal and systemic infections were diagnosed based on the history, physical examination, and laboratory tests. Multinomial logistic regression was used to evaluate the associations between the leprosy reactions and the patients' gender, age, WHO classification and coinfections. RESULTS: Two hundred twenty-five patients were studied. Most of these patients were males (155/225 = 68.8% of an average age of 49.31±15.92 years, and the most prevalent clinical manifestation was the multibacillary (MB form (n = 146, followed by the paucibacillary (PB form (n = 79.

    Full Text Available Leprosy and hepatitis B virus (HBV are highly endemic in some regions of the state of Mato Grosso, in central Brazil. The association of leprosy with HBV and hepatitis C virus (HCV was assessed using a seroprevalence study and 191 leprosy outpatients were included. Demographic data and the clinical classification of leprosy were recorded. Evidence of previous HBV infection was present in 53 patients (27.7%, 95% confidence interval: 21.9-34.5 and two (1% were HBsAg positive. Five (2.6% had antibodies to HCV. The prevalence of previous exposure to HBV was higher than expected for an adult population in central Brazil. In contrast, the prevalence of anti-HCV antibodies was not much higher regarding the age range of participants. HBV markers were associated with a higher number of sex partners and the use of injections without proper sterilisation of the syringes. The number of HBV carriers was small, suggesting that there was no increased likelihood of chronification among these patients.

    This study discusses the relationship between work and living conditions among leprosy patients enrolled in the São Paulo municipal public health system in 1996. Social patterns were studied based on the theory of social determination of the health-disease process. The main purpose of the study was to emphasize evidence of the disease determination network, seeking new knowledge to improve public policies on leprosy. Data were gathered from a sample of leprosy patients registered in the city's public health system. Although patients' families are characterized by a common social thread, different work/life possibilities allow for a classification of patients into three social groups. The majority belong to groups that are marginalized from social production, living in areas where social exclusion is more extreme, on the outskirts of the city. If the trends in this study persist, incident leprosy cases will result from the social exclusion of migrants from Brazil's Southeast and Northeast. The study also discusses the position of young people and female patients in the determination network of this infectious disease in the city of São Paulo.

    Leprosy is an infectious chronic disease with a wide range of clinical and serological manifestations. We report a case of a woman presenting with a malar rash, painless oral ulcers, photosensitivity, arthritis, positive antinuclear antibodies test and leuko-lymphopenia. Our case illustrates an unusual presentation of leprosy initially diagnosed as systemic lupus erythematosus (SLE). After the confirmation of multibacillary leprosy and multidrug therapy recommended by the World Health Organization, a good clinical response was observed. Recognition of rheumatic manifestations in leprosy is important as they may be confused with SLE. A literature review is presented to encourage clinicians to consider leprosy as a differential diagnosis. Specifically in patients with unusual rheumatic manifestations and persistent skin lesions, and when neurological symptoms are present. Leprosy has not been eradicated, so misdiagnosis can be frequent. It is necessary to increase medical practitioner awareness in order start proper treatment. © The Author(s) 2015.

STH can profoundly dysregulate host immune responses towards Th2 bias, which can be restored over time after deworming. We hypothesize that STH co-infection is associated with leprosy reaction (denoted as simply “reaction” herein) occurrence within a co-endemic population. Methods A cohort study was performed on a cohort of Nepalese leprosy patients across treatment and d...

    Leprosy is characterized by a broad spectrum of clinical manifestations that extend from paucibacillary (PB) to multibacillary (MB) depending upon the different immunologic response to the invading of M. leprae 3,4 . It has been widely accepted that genetic predisposition plays the crucial role in the different clinical manifestations. Host susceptibility to leprosy is modified by number of genes via two stages. In the first stage, a group of genes confers susceptibility to leprosy per se; A second group of genes are associated to the type of host immune response and leprosy subtype 5 .

    Full Text Available Introduction The immune response caused by Mycobacterium leprae is a risk factor for the development of oxidative stress (OS in leprosy patients. This study aimed to assess OS in leprosy patients before the use of a multidrug therapy. Methods We evaluated the nitric oxide (NO concentration; antioxidant capacity; levels of malondialdehyde, methemoglobin and reduced glutathione; and the activity of catalase and superoxide dismutase (SOD in leprosy patients. Results We observed lower SOD activity in these leprosy patients; however, the NO levels and antioxidant capacity were increased. Conclusions The infectious process in response to M. leprae could primarily be responsible for the OS observed in these patients.

    The aim of the present study was to clinically evaluate the oral mucosa lesions of leprosy patients during and after multi-drug therapy. Clinical examination, medical and dental history examination was performed in 100 leprosy patients. The results revealed that 71 patients, 50 men and 21 women, exibited oral lesions. The most frequent lesions were: fissured tongue (18 cases), inflammatory papillary hyperplasia (16 cases), chronic atrophic candidiasis (10 cases), fibroma (10 cases), erythematous candidiasis (eight cases), and traumatic ulceration (seven cases). We conclude that leprosy-related lesions are not present in patients undergoing treatment for leprosy, probably due to response to multidrug therapy.

    Leprosy remains an important cause of preventable disabilities. After the advent of multidrug therapy, new leprosy cases have come down dramatically. Despite this achievement, India, which contributes 60% of the global leprosy burden, faces some challenges to eliminate the disease, including active transmission in the community and delayed diagnosis of leprosy patients. The objectives of the study were 1) to determine sociodemographic and clinical characteristics of newly diagnosed adults and children (less than 15 years) with leprosy and their trends over time (2008-2015) and 2) to describe the profile of surgical procedures among leprosy patients registered for reconstructive surgeries during 2006-2015. Retrospective descriptive study was conducted involving a record review of new patients with leprosy registered in Vimala Dermatological Centre, Mumbai. A total of 578 new leprosy cases were registered in the hospital during 2008-2015. There has been a steady increase in the trend of child cases (less than 15 years) registered in the facility (from 3% in 2008 to 18% in 2015), x 2 =12.11, p< 0.01. The majority of the patients (68%) were migrants of Uttar Pradesh and Bihar. Targeting children and migrants and ensuring early diagnosis and treatment initiation are essential components for leprosy elimination in an urban metropolis in India.

This case-series study evaluates the benefits of the combined use of steroids and MDT in preventing nerve damage in patients with pure neural leprosy (PNL. In addition to MDT, 24 patients (88% male aged 20-79 years, median=41 received a daily morning dose of 60 mg prednisone (PDN that was gradually reduced by 10 mg during each of the following 5 months. PNL was clinically diagnosed and confirmed by nerve histopathology or PCR. A low prevalence (8.3% of reaction was observed after release from treatment. However, most of the clinical parameters showed significant improvement; and a reduction of nerve conduction block was observed in 42% of the patients. The administration of full-dose PDN improved the clinical and electrophysiological condition of the PNL patients, contributing to the prevention of further neurological damage.A poliquimioterapia (PQT, com rifampicina, dapsona, e clofazimina, trata a infecção na hanseníase, mas é insuficiente para interromper ou prevenir o comprometimento neurológico que causa as incapacidades e desabilidades, nesta enfermidade.

    A lot of time and money was needed during the diagnosis and treatment process of leprosy, the delayed leprosy would also impair the labor capability of patients as well, and these put a heavy burden for the leprosy patients. The migrant leprosy patient is a special group and need more concern. Our goal was to assess the economic burden of leprosy on migrant and resident patient populations in Guangdong province, China. We conducted a population-based cross-sectional survey from February to July of 2016. A self-designed questionnaire was administered to leprosy patients who: (1) had registered in Leprosy Management Information System in China (LEPMIS) by the end of February 2016, (2) had received multiple drug treatment (MDT) drugs at a local leprosy control institution for three consecutive months or had had at least one physical check in the past half year, and (3) were willing to take part in the investigation and give informed written consent. Demographic characteristics, Financial and disease information, and costs before and after leprosy diagnosis were collected and compared using t-test and χ2 test. A total of 254 participants completed the questionnaires, including 168 males and 86 females. Migrants and residents accounted for 33.9% and 66.1% of patients, respectively. Among migrant patients, the median cost before diagnosis was $131.6 (39.2-450.9), the median yearly cost of leprosy treatment after diagnosis was $300.6 (158.4-868.5), and the median yearly cost of leprosy complications was $69.5 (11-178.4). In comparison, among residents the median yearly costs were $152.4 (30.7-770.9) pre-diagnosis, $309.7 (103.2-1016.7) after diagnosis, and $91.9 (32.6-303.1) for leprosy complications. Base on this, we determined that the median yearly total expense after diagnosis amounted to 15% of migrant and 38% of resident patients' annual income. Leprosy places a heavy economic burden on both migrant and resident leprosy patients and governmental policies and

    Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC), which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

    Full Text Available Public health policies continue to play important roles in national and international health reforms. However, the influence and legacies of the public health eras during which such policies are formulated remain largely underappreciated. The limited appreciation of this relationship may hinder consistent adoption of public health policies by nation-states, and encumber disinvestment from ineffective or anachronistic policies. This article reviews seven public health eras and highlights how each era has influenced international policy formulation for leprosy control—“the fertile soil for policy learning”. The author reiterates the role of health leadership and health activism in facilitating consistency in international health policy formulation and implementation for leprosy control.

    The physiological changes in obese subjects can modify the pharmacokinetic profiles of drugs influencing the therapeutic efficacy. In this study, the authors compare plasma dapsone trough levels of multibacillary leprosy subjects stratified by body mass index (BMI) to evaluate if obesity plays a significant role on drug levels. The relationship between drug levels and BMI was also determined. Dapsone was measured by high-performance liquid chromatography and BMI based on World Health Organization criteria. At steady state, the median plasma dapsone trough level was significantly lower in obesity class 2 group, when compared with other groups, but they were similar between normal weight and preobesity groups. A weak association between drug levels and BMI was observed. Obesity promotes a significant reduction in plasma dapsone trough levels of subjects with multibacillary leprosy with a weak association between drug levels and BMI.

    Full Text Available Abstract INTRODUCTION: This study evaluated leprosy rates in Rio Grande do Sul, an area with a historically low prevalence. However, recent studies are lacking. METHODS: Data extracted from a National Database were analyzed for clinical features and compared to 1980s data. Tendency was assessed via stationarity analysis. RESULTS: Between 1990 and 2011, 4,770 cases were reported (0.21/10,000 inhabitants; 95% CI = 0.19-0.24. Detection was slightly higher among males, 1.9% cases were among children and most multibacillary (74.7% at diagnosis. CONCLUSIONS: Leprosy is controlled in RS, but most cases are multibacillary. Early identification is important to avoid disabilities due to late diagnosis.

    Full Text Available The diagnosis of single-lesion paucibacillary leprosy remains a challenge. Reviews by expert dermatopathologists and quantitative polymerase chain reaction (qPCR results obtained from 66 single-plaque biopsy samples were compared. Histological findings were graded as high (HP, medium (MP or low (LP probability of leprosy or other dermatopathy (OD. Mycobacterium leprae-specific genes were detected using qPCR. The biopsies of 47 out of 57 clinically diagnosed patients who received multidrug therapy were classified as HP/MP, eight of which were qPCR negative. In the LP/OD (n = 19, two out of eight untreated patients showed positive qPCR results. In the absence of typical histopathological features, qPCR may be utilised to aid in final patient diagnosis, thus reducing overtreatment and delay in diagnosis.

    Full Text Available Osteomyelitis, a major complication of neuropathic feet in leprosy may occur as a result of infiltration of Mycobacterium leprae in the periosteum of bones or due to secondary bacterial infection of chronic plantar ulcer. There is no effective treatment for healing of planter ulcer and osteomyelitis. Keeping in mind of the limitation of conservative treatment, twenty patients who completed with multi drug therapy but suffering from neuropathic foot with ulcer was treated with Mercurius solubilis, a homoeopathic medicine in 200 potency for one year. All these patients had different degrees of osteomyelitic changes and after treatment showed regeneration and remodeling of bones which may be considered as significant improvement. Based on the radiological finding it may be concluded that Mercurius solubilis found to be effective in the treatment of osteomyelitis in leprosy affected patients.

    Leprosy is a chronic disease caused by infection with Mycobacterium leprae, an obligate intracellular parasite. A problem in studying the transmission of leprosy is the small amount of variation in bacterial genomic DNA. The discovery of variable number of tandem repeats (VNTRs) allowed the detection of strain variation in areas with a high prevalence of leprosy. Four genotypes of M. leprae based on three single-nucleotide polymorphism (SNPs) were also discovered to be useful for analysis of the global spread of leprosy. In this present study, we examined the allelic diversity of M. leprae at 16 select VNTR and three SNP loci using 89 clinical isolates obtained from patients mainly from the neighbouring states of São Paulo and Rio de Janeiro Brazil. By use of a PCR-RFLP-based procedure that allows the recognition of SNP types 3 and 4 without the need for the more expensive DNA sequencing steps, characterisation of the main M. leprae genotypes was easy. When applied on the study population, it was found that the SNP type 3 is most frequent in these two states of Brazil, and that VNTRs provided further discrimination of the isolates. Two Short Tandem Repeats (STRs) were monomorphic, with the remaining 14 STRs represented by two to 18 alleles. Epidemiological associations with township or state were not evident in this random collection and require further investigations. In phylogenetic trees, branches formed by all 16 STRs clearly separated SNP type 3 organisms from the other types while the allelic patterns of two minisatellite loci 27-5 and 12-5 were highly correlated with SNP type 3. This strain typing study provide the basis for comparison of M. leprae strain types within Brazil and with those from other countries, and informed selection of genomic markers and methods for future studies.

    We report on a 60-year-old man suffering from borderline leprosy. He was treated many times with DDS and Clofazimin and underwent the so-called multiple drug treatment (MDT). Under this therapy, the patient developed allergic photodermatitis. Unfortunately his file was lost and, as nobody was informed about his allergic reaction, he was again treated with the preparations mentioned above. Consequently, he responded once more with photodermatitis.

  17. Models for leprosy. An appraisal of graphic representations of the "spectrum" concept as models and a suggestion for a catastrophe theory model for leprosy.

    Science.gov (United States)

    Srinivasan, H

    1984-09-01

    Graphic representations of the spectrum concept of leprosy are examined in some detail as models for this disease. This reveals that this concept is somewhat inadequate and that the spectrum metaphor may itself be inappropriate because, by its very linearity of logic, it may not be able to depict the nonlinear behavior of leprosy properly. The assumptions underlying this concept and their logical consequences, brought out by the graphic representations, include an invariable relation between CMI and BI, identity of one type of leprosy with one specific level of CMI, a fixed sequence of types, and the consequent impossibility of skipping the sequence. However, our experience with leprosy does not bear out these assumptions. Further, development and progress of leprosy from a normal (nonleprous) state cannot be represented in these models. A search for alternative conceptual models therefore appears reasonable and even necessary. The catastrophe theory (a branch of topology in mathematics) describes a number of models for explaining how continuous causes could produce sudden or discontinuous changes. Of the various catastrophe theory models available, the relatively simple "cusp" model appears capable of application to leprosy. This model, as applied here, requires two control factors (identified tentatively as the amount of dead bacilli and the amount of living bacilli or their indicators) and one pattern of behavior, identified as progress towards limited or extensive disease. This model suggests under what conditions leprosy will change from one type to another and whether that will happen gradually or suddenly. It also suggests that for certain values of control factors the disease may manifest in one of two forms of borderline leprosy, and that lesions very similar to start with can progress to quite different states under similar conditions of change. The behavior of leprosy agrees more or less with that suggested by this model. The cusp model thus seems to: a

    To Study the incidence and clinical characteristics of dapsone hypersensitivity syndrome (DHS) among MDT-treated leprosy patients from 2006 to 2009 in China. A retrospective survey was carried out throughout China using a specially designed questionnaire. From 2006 to 2009, there were 63 new patients reported to have DHS with an incidence of 1.0%. Among these patients, 13 were complete types of DHS, the others were incomplete ones. The average age of patients with DHS was 38 years and the male to female ratio was 2.15. The average incubation period from taking dapsone to DHS onset was 32.8 days (2-6 weeks). There were 60 (95.2%) patients who presented with various skin lesions, 56 (88.9%) with fever, 40 (63.5%) with hepatic damage and 22 (34.9%) with lymphopathy. Seven patients died with a death rate of 11.1% among all patients with DHS. DHS is a serious adverse event resulted from dapsone. It can occur in a small number of new leprosy patients treated with dapsone containing regimen. Some patients may die of DHS if not taking timely and adequate management. Therefore local doctors should pay an attention to DHS among leprosy patients newly treated with the dapsone-containing MDT regimen.

    Despite a natural reservoir of Mycobacterium leprae limited to humans and free availability of an effective antibiotic treatment, more than 200,000 people develop leprosy each year. This disease remains a major cause of disability and social stigma worldwide. The cause of this constant incidence is currently unknown and indicates that important aspects of the complex relationship between the pathogen and its human host remain to be discovered. An important contribution of host genetics to susceptibility to leprosy has long been suggested to account for the considerable variability between individuals sustainably exposed to M. leprae. Given the inability to cultivate M. leprae in vitro and in the absence of relevant animal model, genetic epidemiology is the main strategy used to identify the genes and, consequently, the immunological pathways involved in protective immunity to M. leprae. Recent genome-wide studies have identified new pathophysiological pathways which importance is only beginning to be understood. In addition, the prism of human genetics placed leprosy at the crossroads of other common diseases such as Crohn's disease, asthma or myocardial infarction. Therefore, novel lights on the pathogenesis of many common diseases could eventually emerge from the detailed understanding of a disease of the shadows. Copyright © 2013 Elsevier Masson SAS.

    Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin biopsies were performed when the clinical findings suggested leprosy. Anti-phenolic glycolipid antibodies in blood were determined in special cases. 86 % of the 2 844 school children were examined; 833 had skin diseases and 16 % of these required evaluation by specialists. Four new cases of paucibacillary leprosy, two indeterminate and two primary polyneuritic cases were found. Pediculosis capitis, pityriasis alba, tinea versicolor, hypopigmented nevus, insect bites and miliaria were frequently detected. BCG vaccination scars were absent in 387 children; following several logistical problems, they were vaccinated. Four children had signs of childhood abuse. An 11-year-old girl presented hypopigmented mycosis fungoides. All diseases and conditions found were treated. The community received information regarding the results, emphasising the importance of an early diagnosis of leprosy. The incidence of leprosy found (16/10,000) was 123 times higher than the rest of the country's incidence. It is advisable to continue clinical examinations in Agua de Dios and research into risk factors for acquiring leprosy.

    Full Text Available It is imperative to consider the meaning of leprosy and everyday experiences of people affected by leprosy and key persons in the community if one aims to make leprosy services more effective, which appears necessary in Indonesia given the large numbers of new cases detected annually. However, little is written in the international literature about the experiences of people currently being treated for leprosy, those cured, or other key informants. This paper analyses the narratives of the people by drawing upon in-depth interviews with 53 participants and 20 focus groups discussions. The participants were purposively selected. We provide insights into the experiences of people and the meaning they give to leprosy and highlight aspect of aetiology, spirituality, religion, darkening of the skin, and sorcery. We also examine experiences of seeking care and focused on the impact of the disease in particular on the elderly and children. In conclusion, the continued need for implementation of leprosy services in Indonesia is very evident. The diversities in people’s experiences with leprosy indicate a demand for responsive leprosy services to serve the diverse needs, including services for those formally declared to be “cured.”

    Full Text Available Although BCG has been found to impart protection against leprosy in many populations, the utility of repeat or booster BCG vaccinations is still unclear. When a policy of giving a second BCG dose to school children in Brazil was introduced, a trial was conducted to assess its impact against tuberculosis, and a leprosy component was then undertaken in parallel.to estimate the protection against leprosy imparted by a second dose of BCG given to schoolchildren.This is a cluster randomised community trial, with 6 years and 8 months of follow-up.City of Manaus, Amazon region, a leprosy-endemic area in Brazil.99,770 school children with neonatal BCG (aged 7-14 years at baseline, of whom 42,662 were in the intervention arm (revaccination.BCG given by intradermal injection.Leprosy (all clinical forms.The incidence rate ratio of leprosy in the intervention over the control arm within the follow-up, in schoolchildren with neonatal BCG, controlled for potential confounders and adjusted for clustering, was 0.99 (95% confidence interval: 0.68 to 1.45.There was no evidence of protection conferred by the second dose of BCG vaccination in school children against leprosy during the trial follow-up. These results point to a need to consider the effectiveness of the current policy of BCG vaccination of contacts of leprosy cases in Brazilian Amazon region.

    Full Text Available Abstract Background Although leprosy was eliminated globally in 2000, the disease continues to be the significant cause of peripheral neuropathy, disability and disfigurement in some developing countries. However, recent population-based prevalence data are lacking to inform evidence-based renewed commitment for the final push for leprosy elimination at national and sub-national levels. Methods Community camp-based cross-sectional descriptive study was conducted in four selected districts. World Health Organisation guidelines and tools for leprosy elimination monitoring were used to evaluate the Malawi National Leprosy Programme. Results A total of 6,338 people (60% females, 35% children aged less than 15 years were examined for leprosy and other skin diseases. Prevalence of skin diseases was 18%, the commonest being fungal (9%, eczema/dermatitis (3% and leprosy (1%. Of the fungal skin conditions, pityriasis versicolor and Tinea capatis were the commonest (22% and 21% respectively then Tinea corporis (9%, Tinea cruris (6% and Tinea pedis (2%. A total of 66 leprosy cases were detected out of 6,338 people screened giving a prevalence of 104.1 per 10,000 population (range by district 67.1 to 194.1. Of the leprosy cases, 37 were new, 6 were defaulters and 23 were on treatment, 30 were females and 9 were children aged less than 15 years old. Of the 37 new leprosy cases, 9 (24.3% were children, 25 (67.6% had 1–5 leprosy lesions and 8 (21.6% had grade 2 disability. The most frequent location of leprosy lesions was the head and neck (24.1%, arms (24.1%, chest (17.2%, legs (13.8%, back (13.8% and abdomen (7.0%. Between 2006 and 2011, trends of leprosy prevalence and detection increased, prevalence/detection ratios were over 1 and cure rates by cohort analysis of 2009 multibacillary and 2010 paucibacillary cases were 33% and 63% respectively far below the expected 80% although the national prevalence remained at less than 1 case per 10

    With the promotion of community-based rehabilitation (CBR) as a solution to health-related issues across the global South, leprosy colonies have long been out of vogue for nongovernmental organizations and State institutions alike. Such colonies, however, have endured. As is being increasingly recognized by those working in the leprosy field, such places have played a particular role not only in the provision of leprosy-related care but also in forging new and collective identities for people affected by leprosy that might otherwise not have been possible. In this article, I draw on ethnographic fieldwork in one such colony in coastal Andhra Pradesh, South India, and explore the values invested in it as a particular kind of place; its geographical location on the peripheries; and its architecture and layout (inspired in part by colonial sanatoriums), which have particular implications for how leprosy and its ramifications are constituted and managed.

    Multidrug therapy for leprosy is currently done with dapsone, clofazimine and rifampicin. Dapsone is known to cause hemolytic anemia (HA) and this adverse event during MDT seems to be more frequent than reported. The aim of this report is to discuss and grade HA due to dapsone during MDT treatment for leprosy. This is a retrospective study of 194 leprosy patients from a Leprosy Control Programme Unit in Vit6ria-ES, Brazil. HA was observed in 48 (24.7%) patients and occurred within the first 3 months in 51% of these. Mean hematocrit levels fell from 38.5 to 31.5 and hemoglobin from 12.8 to 10.3. Dapsone used in the MDT regime for leprosy decreases the hematocrit and hemoglobin levels due to a low grade hemolysis, which can result in significant anemia.

    Full Text Available Background: Genomic reduction helps obligate intracellular microbes to survive difficult host niches. Adaptation of Mycobacterium leprae in cases of pure neural leprosy (PNL in the intracellular niche of peripheral nerves can be associated with some gene loss. Recently, a stable but variable number of tandem repefzats (TTC have been reported in strains of M. leprae. FolP and rpoB genes are the two common mutation sites which deal with the susceptibility of the bacteria to drugs. Aim: We attempted to find if genomic reduction of M. leprae in context of these TTC repeats or mutations in folP1 and rpoB can be the reason for the restriction of M. leprae in the nerves in PNL. Materials and Methods: DNA extracts taken from fine needle aspiration of affected nerves of 24 PNL cases were studied for tandem repeats with 21TTC primer in multiplex-PCR. Mutations were also studied by PCR Amplification of SRDR (Sulphone Resistance Determining Region of the folP1 and multiple primer PCR amplification refractory mutation system (MARS of the rpoB. Results: Of the 24 PNL, only 1 patient showed mutation in the rpoB gene and none in the folp1 gene. Studying the mutation in TTC region of the M. leprae gene we found that all the cases have a loss of a few bases in the sequence. Conclusion: We can conclude that there is consistent loss in the bases in the TTC region in all cases of pure neural Hansen and we postulate that it may be an adaptive response of the bacteria to survive host niche resulting in its restriction to peripheral nerves.

    Full Text Available A broad variety of factors have been associated with leprosy among contacts, including socioeconomic, epidemiological, and genetic characteristics. Data from 7,174 contacts of leprosy patients from a leprosy outpatient clinic in Rio de Janeiro, Brazil, 1987–2010, were analyzed to investigate the effects of kinship, individual, and contextual factors on leprosy. Multivariate analyses were performed using a robust estimation method. In the prevalence analysis, close kinship (sibling OR = 2.75, offspring OR = 2.00, and other relatives OR = 1.70, socioeconomic factors, and the duration of exposure to the bacillus were associated to leprosy. In the incidence analysis, significant risks were found for all categories of kinship (parents RR = 10.93, spouse, boyfriend/girlfriend, and bride/groom RR = 7.53, sibling RR = 7.03, offspring RR = 5.34, and other relatives RR = 3.71. Once the treatment of the index case was initiated, other factors lost their significance, and the index case bacteriological index and BCG (Bacillus Calmette-Guérin vaccine protection had a greater impact. Our findings suggested that both genetic susceptibility and physical exposure play an important role in the epidemiology of leprosy, but it was not possible establishing the role of genetic factor. Analyses of other factors related to the genotype of individuals, such as genetic polymorphisms, are needed.

    Rogerio Del Arco

    Full Text Available ABSTRACT Objective: to identify the difficulties in diagnosing and treating neuropathic pain caused by leprosy and to understand the main characteristics of this situation. Methods: 85 patients were treated in outpatient units with reference to leprosy and the accompanying pain. We used a questionnaire known as the Douleur Neuropathic 4 test and we conducted detailed neurological exams. As a result, 42 patients were excluded from the study for not having proved their pain. Results: Out of the 37 patients that experienced pain, 22 (59.5% had neuropathic pain (or a mixture of this pain and their existing pain and of these 90.8% considered this pain to be moderate or severe. 81.8% of the sample suffered with this pain for more than 6 months. Only 12 (54.5% of the patients had been diagnosed with neuropathic pain and in almost half of these cases, this pain had not been diagnosed. With reference to medical treatment (n=12 for neuropathic pain, 5 (41.6% responded that they became better. For the other 7 (58.4% there were no changes in relation to the pain or in some cases the pain worsened in comparison to their previous state. Statistical analysis comparing improvements in relation to the pain amongst the patients that were treated (n=12 and those that were not, showed significant differences (value p=0.020. Conclusion: we noted difficulties in diagnosing neuropathic pain for leprosy in that almost half of the patients that were studied had not had their pain diagnosed. We attributed this to some factors such as the non-adoption of the appropriate protocols which led to inadequate diagnosis and treatment that overlooked the true picture.

  12. Leprosy on Reunion Island, 2005-2013: Situation and Perspectives.

    Full Text Available Reunion Island is a French overseas territory located in the south-western of Indian Ocean, 700 km east of Madagascar. Leprosy first arrived on Reunion Island in the early 1700s with the African slaves and immigration from Madagascar. The disease was endemic until 1980 but improvement of health care and life conditions of inhabitants in the island have allowed a strong decrease in new cases of leprosy. However, the reintroduction of the disease by migrants from endemic neighbouring countries like Comoros and Madagascar is a real and continuing risk. This observational study was then conducted to measure the number of new cases detected annually on Reunion Island between 2005 and 2013, and to describe the clinical features of these patients.Data were collected over two distinct periods. Incident cases between 2005 and 2010 come from a retrospective study conducted in 2010 by the regional Office of French Institute for Public Health Surveillance (CIRE of Indian Ocean, when no surveillance system exist. Cases between 2011 and 2013 come from a prospective collection of all new cases, following the implementation of systematic notification of all new cases. All patient data were anonymized. Among the 25 new cases, 12 are Reunion Island residents who never lived outside Reunion Island, and hence are considered to be confirmed autochthonous patients. Registered prevalence in 2014 was 0.05 /10 000 habitants, less than the WHO's eradication goal (1/10 000.Leprosy is no longer a major public health problem on Reunion Island, as its low prevalence rate indicates. However, the risk of recrudescence of the disease and of renewed autochthonous transmission remains real. In this context, active case detection must be pursued through the active declaration and rapid treatment of all new cases.

  13. Evaluation of qPCR-based assays for leprosy diagnosis directly in clinical specimens.

    Full Text Available The increased reliability and efficiency of the quantitative polymerase chain reaction (qPCR makes it a promising tool for performing large-scale screening for infectious disease among high-risk individuals. To date, no study has evaluated the specificity and sensitivity of different qPCR assays for leprosy diagnosis using a range of clinical samples that could bias molecular results such as difficult-to-diagnose cases. In this study, qPCR assays amplifying different M. leprae gene targets, sodA, 16S rRNA, RLEP and Ag 85B were compared for leprosy differential diagnosis. qPCR assays were performed on frozen skin biopsy samples from a total of 62 patients: 21 untreated multibacillary (MB, 26 untreated paucibacillary (PB leprosy patients, as well as 10 patients suffering from other dermatological diseases and 5 healthy donors. To develop standardized protocols and to overcome the bias resulted from using chromosome count cutoffs arbitrarily defined for different assays, decision tree classifiers were used to estimate optimum cutoffs and to evaluate the assays. As a result, we found a decreasing sensitivity for Ag 85B (66.1%, 16S rRNA (62.9%, and sodA (59.7% optimized assay classifiers, but with similar maximum specificity for leprosy diagnosis. Conversely, the RLEP assay showed to be the most sensitive (87.1%. Moreover, RLEP assay was positive for 3 samples of patients originally not diagnosed as having leprosy, but these patients developed leprosy 5-10 years after the collection of the biopsy. In addition, 4 other samples of patients clinically classified as non-leprosy presented detectable chromosome counts in their samples by the RLEP assay suggesting that those patients either had leprosy that was misdiagnosed or a subclinical state of leprosy. Overall, these results are encouraging and suggest that RLEP assay could be useful as a sensitive diagnostic test to detect M. leprae infection before major clinical manifestations.

  14. Factors preventing early case detection for women affected by leprosy: a review of the literature.

    Price, Victoria Grace

    Although leprosy can affect both sexes equally, it is globally reported that men are affected, or simply report, more often than females at the average ratio of 2:1. If cases are simply not being reported, women may be suffering in silence more often than men, and, therefore, understanding the social reasons for this in a number of countries could support the prevention of long-term disabilities caused as a result of leprosy. The objective of this review is to recognise the current academic literature surrounding the potential factors for late diagnosis of women affected by leprosy, giving possible explanations for the 2:1 gender disparity observed in case detection globally. It is hoped that health practitioners will become more equipped to recognise these barriers and ensure they are doing whatever possible to encourage women to report the early symptoms of leprosy. The review used a systematic search process in order to identify gender-related publications using robust research, useful for gleaning a cross-cultural perception of issues women may confront on the prospect of a diagnosis of leprosy. Identifying 12 publications from just five countries, the review found there to be four overarching areas which may be considered barriers more often faced by women: societal stigma; women's dependence and low status; self-stigmatising attitudes; and the gender insensitivity of leprosy services. Stigma surrounding leprosy experienced from these four overarching areas can all be attributed to the later diagnosis of women affected by leprosy, in relation to their male counterparts. The need for future research surrounding the specific experience of women affected by leprosy is pressing.

    The World Health Organization targeted to eliminate leprosy from the world with multidrug therapy (MDT) by 2000. But, leprosy remains a problem in Essimbiland of Menchum Division of Cameroon, with a prevalence of 1.7/10,000 and high rate of case detection in children. To assess knowledge and practices on the cure of leprosy, treatment duration, drug availability and problems faced by leprosy patients acquiring drugs in order to enhance MDT implementation and leprosy elimination in Menchum and Boyo divisions. Observational study in which a structured questionnaire was administered to leprosy patients, their contacts and a control group. 480 respondents were interviewed and 405 (84.8%) (95% confidence interval [CI]: 81.6-87.2%) knew that leprosy can be cured. These respondents comprised 166 (92.2%) of 180 contacts, 129 (93.5%) of 138 patients and 110 (67.9%) of 162 controls. Two hundred and fourteen (44.6%) (95% CI: 40.1-48.9%) respondents knew that leprosy treatment is free, comprising of 110 (51.4%) patients, 99 (46.3%) contacts and five (2.3%) controls. A statistically significant difference in the knowledge on free treatment of leprosy was found to exist between leprosy patients, contacts and controls, with leprosy patients having a better knowledge (79.71%) (95% CI: 73-86.42%), followed by contacts (55.0%) (95% CI: 47.73-62.26%) and controls (3.1%) (95% CI: 0.43-5.77%) (P = 0.00). Pertinent problems faced by patients in getting MDT included distant health facilities and poor road network (91[19.0%]), lack of confidence in treatment (56 [11.7%]), MDT shortage (45 [9.4%]), few health facilities (52 [10.8%]), gratification demands (25 [5.2%]), disturbance from other illnesses (24 [5.0]), ignorance (21 [4.4%]) and poor relationship with nurses (24 [5.0%]). Patients still face problems in getting free MDT. Better MDT implementation and leprosy elimination strategies are proposed.

    Hansen disease, commonly known as leprosy, is uncommon in the United States and poses difficult diagnostic and treatment challenges. A 10-year-old girl was adopted from Ethiopia with a history of "multibacillary leprosy" and "multidrug treatment" for 12 months. Three months after her arrival in the United States and 4 months after treatment was completed, she presented with new papules and plaques on her left nose and ear. Herein, we present her case and review current treatment options in leprosy in children and the management of immunologic reactions.

    Full Text Available Abstract Background Mycobacterium leprae is the only pathogenic bacteria able to infect peripheral nerves. Neural impairment results in a set of sensitive, motor and autonomic disturbances, with ulcers originating primarily on the hands and feet. The study objectives were to analyze the clinic-epidemiological characteristics of patients attended at one specialized dressing service from a leprosy-endemic region of the Brazilian Amazon and to evaluate the effect of low level laser therapy (LLLT on wound healing of these patients. Methods Clinic-epidemiological evaluation of patients with leprosy sequelae was performed at the reference unit in sanitary dermatology of the state of Pará in Brazil. We conducted anamnesis, identification of the regions affected by the lesions and measurement of ulcer depth and surface area. After that, we performed a randomized clinical trial. Fifty-one patients with ulcers related to leprosy were evaluated, twenty-five of them were randomly assigned to a low level laser therapy group or a control group. Patients were treated 3 times per week for 12 weeks. Outcome measures were ulcer surface area, ulcer depth and the pressure ulcer scale for healing score (PUSH. Results Ninety-seven ulcers were identified, with a mean (SD duration of 97.6 (111.7 months, surface area of 7.3 (11.5 cm2, and depth of 6.0 (6.2 mm. Statistical analysis of the data determined that there were no significant differences in the variables analyzed before and after treatment with low level laser therapy. Conclusions Ulcers in patients with leprosy remain a major source of economic and social losses, even many years after they have been cured of M. leprae infection. Our results indicate that it is necessary to develop new and more effective therapeutic tools, as low level laser therapy did not demonstrate any additional benefits to ulcer healing with the parameters used in this study.

    A study was made in a group of 117 leprosy patients in differents clinical conditions, under treatment, in drug rest or virgins of treatment. They were divided in sub-groups for the following tests: the radioiodine uptake of 2-24 hours; neck-thigh ratio; thyrobinding index; protein-bound radioiodine (PB 131 I) levels of plasma. The results led to the following conclusions: 1) Leprosy patients present a low uptake in conjunction with a decrease in the velocity of thyroid clearance in the majority of the cases. Even the remaining presented values within the low limit of normality; 2) In view of these results, the tests were repeated after thyroid stimulating hormone (TSH) with exogenous TSH, in the sub-group of patients virgin of treatment. With the positive response observed (increase in the uptake, in the neck-thigh ratio and the PB 131 I) the low uptake was considered secondary with regard to a deficit of the endogenous TSH; 3) The TBI and PB 131 I tests were not in sufficient agreement for an appraisal of the phase of organic binding and release of hormone [pt

Biopsies were compared with those taken from the same body site in the remission stage of the same patient. We found a relative increase of TMC in the inflammatory infiltrate of the reactional biopsies compared to the post-reactional biopsy. Also, the total number of mast cells and the TMC/TCMC ratio in the inflammatory infiltrate was significantly higher than in the intervening dermis of the biopsies of both periods. No significant difference was found regarding neuroptide expression in the reactional and post-reactional biopsies. The relative increase of TMC in the reactional infiltrates could implicate this mast cell subset in the reported increase of the immune response in leprosy reactions.

    Citrus leprosis is the most important viral disease of citrus. Knowledge of its spatiotemporal structure is fundamental to a representative sampling plan focused on the disease control approach. Such a well-crafted sampling design helps to reduce pesticide use in agriculture to control pests and diseases. Despite the use of acaricides to control citrus leprosis vector (Brevipalpus spp.) populations, the disease has spread rapidly through experimental areas. Citrus leprosis has an aggregate spatial distribution, with high dependence among symptomatic plants. Temporal variation in disease incidence increased among symptomatic plants by 4% per month. Use of acaricides alone to control the vector of leprosis is insufficient to avoid its incidence in healthy plants. Preliminary investigation into the time and space variation in the incidence of the disease is fundamental to select a sampling plan and determine effective strategies for disease management. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

    Leprosy is one of the oldest ailments known to the mankind. Many of the ancient texts and scriptures reveal that leprosy was not categorised as a specified disease but was grouped along with other skin diseases. However, in certain texts categorical mention of this disease does exist. The prime objective of this article is to highlight the age old traditional line of perception about this disease. A literature review was done to up-date the socio-cultural perception of leprosy in Indian religions and ancient texts. References were obtained through examining relevant bibliographies and the views/suggestions of eminent scholars engaged in this field were also included. An analysis of the secondary sources of data, particularly the ancient texts reveals that in good old days, leprosy had been considered to be an infliction of wrong-doings and sins. This viewpoint has been significantly reflected in these texts.

    As we approach the third decade since the WHO started addressing the eradication of poliomyelitis and leprosy, a reflection of the previous campaigns efficacy and an evaluation of further elimination feasibility is important to adapt and intensify the next steps. We performed a critical review of the poliomyelitis and leprosy eradication campaigns to evaluate their technical and operational feasibilities. Vaccination and active case search are highly effective tools against poliomyelitis. If political stability and good vaccination coverage is achieved, poliomyelitis will be an easy target for eradication. Leprosy, on the other hand, faces many barriers towards elimination. The lack of a high efficacy vaccine, the long asymptomatic but infective period, the lack of screening tests and a poorly established elimination target, prevents this disease from being eliminated. In a world where resources and funding are limited, it is apparent that poliomyelitis is a more feasible target for elimination than leprosy.

    Leprosy, or Hansen's disease, continues to be feared and poorly understood in the United States, where knowledge of the disease is limited and prevalence is low. The presence of leprosy among immigrants, however, provides fuel for those with an anti-immigration agenda. In recent years, there have been several examples of popular media distortions of statistics and of information on leprosy's properties and contagiousness. As in previous eras of U.S. history, public fears about leprosy seem to be related to anti-immigration or nativist sentiment, which often mask underlying concerns about the potential economic threat of immigrant populations. In this article, I analyse the role of the U.S. media and other stakeholders who may have an interest in generating public fear associated with leprosy, in presenting and at times manipulating data about the disease to create an association between leprosy and undocumented immigration.

    Full Text Available INTRODUCTION: This study evaluated the intracellular profile of interleukin-2 (IL-2, interleukin-4 (IL-4, interleukin-10 (IL-10 and interferon-γ (IFN-γ in peripheral blood mononuclear cells (PBMCs from leprosy patients based on oral infections presence to determine whether these coinfections could be associated with pro-inflammatory activity in leprosy. METHODS: Leprosy patients regardless of clinical form and specific leprosy treatment (n=38 were divided into two groups: Group I - leprosy patients with oral infections (n=19, and Group II - leprosy patients without oral infections (n=19. Non-leprosy patients presenting oral infections were assigned to the control Group (n=10. Intracellular IL-2, IL-4, IL-10 and IFN-γ production was evaluated by flow cytometry (FACS before and 7 days after controlling the oral infection in the Group I, before and 7 days after dental prophylaxis in the Group II, and during oral infection process in control Group. RESULTS: Low percentages of CD3+ lymphocytes bearing IL-2, IL-10 and IFN-γ were observed in the Group I and Group II at baseline and 7 days after therapy or prophylaxis compared to controls. Group I showed reduced percentages of IL-4 at baseline and 7 days after therapy compared to controls, or at baseline of Group II, and the Group II showed reduced percentages of CD3+ cells bearing IL-4 compared to control. An increase of the percentages of CD3+cells bearing IL-4 was observed in the Group I after the oral infections treatment. CONCLUSIONS: The occurrence of oral infections favors the intracellular cytokines expression and, probably, the inflammatory reaction operating as a stimulatory signal triggering the leprosy reactions.

    Background: Skin, which is the largest organ in the body, carries immense psychological significance. Disfiguring skin disorders may impact negatively on the mental health of individuals. Aim: This study compared the psychiatric morbidity of subjects with leprosy and albinism. Subjects and Methods: One hundred subjects with leprosy and 100 with albinism were interviewed. Sociodemographic questionnaire and General Health Questionnaire (GHQ-28) assessed the sociodemographic characteristics and psychiatric morbidity, respectively. GHQ positive cases and 10% of noncases for each group were interviewed with Mini International Neuropsychiatric Inventory for specific ICD-10 diagnoses. Results: Fifty-five percent (55/100) subjects with leprosy were GHQ positive cases while 41% (41/100) with albinism were GHQ positive cases. The risk of developing psychiatric morbidity was significantly higher in subjects with leprosy than in subjects with albinism (OR = 1.76, CI = 1.00 – 3.08, P = 0.04). The prevalence of specific psychiatric disorders among subjects with leprosy were depression 49% (49/100), generalized anxiety disorder (GAD) 18% (18/100), alcohol/drug abuse 16% (16/100), whereas in albinism depression was 51% (51/100), GAD 27% (27/100), and alcohol/drug abuse 7% (7/100). Male, married and uneducated subjects with leprosy had significantly higher psychiatric morbidity than the male, married and uneducated subjects with albinism, respectively. Conclusion: Psychiatric morbidity was higher in subjects with leprosy than in subjects with albinism. Male, married and uneducated subjects with leprosy significantly had higher morbidity than male, married and uneducated subjects with albinism respectively. PMID:26097762

    Full Text Available Abstract: An integrative literature review was conducted to synthesize available publications regarding the potential use of serological tests in leprosy programs. We searched the databases Literatura Latino-Americana e do Caribe em Ciências da Saúde, Índice Bibliográfico Espanhol em Ciências da Saúde, Acervo da Biblioteca da Organização Pan-Americana da Saúde, Medical Literature Analysis and Retrieval System Online, Hanseníase, National Library of Medicine, Scopus, Ovid, Cinahl, and Web of Science for articles investigating the use of serological tests for antibodies against phenolic glycolipid-I (PGL-I, ML0405, ML2331, leprosy IDRI diagnostic-1 (LID-1, and natural disaccharide octyl-leprosy IDRI diagnostic-1 (NDO-LID. From an initial pool of 3.514 articles, 40 full-length articles fulfilled our inclusion criteria. Based on these papers, we concluded that these antibodies can be used to assist in diagnosing leprosy, detecting neuritis, monitoring therapeutic efficacy, and monitoring household contacts or at-risk populations in leprosy-endemic areas. Thus, available data suggest that serological tests could contribute substantially to leprosy management.

    Studies have demonstrated that the geographical distribution of leprosy is related to different socioeconomic factors. This article aims to study the geographical distribution of leprosy in the state of Rio de Janeiro. The cases of leprosy reported in the 2001-2012 period were mapped according to municipality. Epidemiological and socioeconomic indicators were calculated. The ArcMap program was used for the construction of maps and Earth View to calculate the Bayesian rate. It was observed that leprosy is presented in hyper-endemic levels especially in the metropolitan area. However, there is also a reduction of the detection rate in the most recent study period. In municipalities in the metropolitan region and the north western region detection in children under 15 is high, indicating an active transmission situation. In municipalities in the south-central region and especially in the coastal region, there was a high proportion of cases diagnosed with level II disability, reflecting late diagnosis. There was no linear correlation between socioeconomic indicators and leprosy rate. These results contribute to the analysis of the geographical distribution of leprosy, important for the identification of areas for resource allocation, aiming to control and eliminate the disease.

    Full Text Available Mycobacteria leprae(leprosy and HIV coinfection are rare in Kenya. This is likely related to the low prevalence (1 per 10,000 of population of leprosy. Because leprosy is no longer a public health challenge there is generally a low index of suspicion amongst clinicians for its diagnosis. Management of a HIV-1-leprosy-coinfected individual in a resource-constrained setting is challenging. Some of these challenges include difficulties in establishing a diagnosis of leprosy; the high pill burden of cotreatment with both antileprosy and antiretroviral drugs (ARVs; medications’ side effects; drug interactions; scarcity of drug choices for both diseases. This challenge is more profound when managing a patient who requires second-line antiretroviral therapy (ART. We present an adult male patient coinfected with HIV and leprosy, who failed first-line antiretroviral therapy (ART and required second-line treatment. Due to limited choices in antileprosy drugs available, the patient received monthly rifampicin and daily lopinavir-/ritonavir-based antileprosy and ART regimens, respectively. Six months into his cotreatment, he seemed to have adequate virological control. This case report highlights the challenges of managing such a patient.

    Summary Introduction Leprosy is a public health problem in Brazil where 31,044 new cases were detected in 2013. Rio Grande do Norte is a small Brazilian state with a rate of leprosy lower than other areas in the same region, for unknown reasons. Objectives We present here a review based on the analysis of a database of registered leprosy cases in Rio Grande do Norte state, comparing leprosy's geographic distribution among municipalities with local socio-economic and public health indicators and with historical documents about human migration in this Brazilian region. Results The current distribution of leprosy in Rio Grande do Norte did not show correlation with socio-economic or public health indicators at the municipal level, but it appears related to economically emerging municipalities 100 years ago, with spread facilitated by railroads and train stations. Drought-related migratory movements which occurred from this state to leprosy endemic areas within the same period may be involved in the introduction of leprosy and with its present distribution within Rio Grande do Norte. Conclusions Leprosy may disseminate slowly, over many decades in certain circumstances, such as in small cities with few cases. This is a very unusual situation currently and a unique opportunity for epidemiologic studies of leprosy as an emerging disease. PMID:26964429

Há poucos estudos que tratam deste assunto na era da multidrogaterapia. OBJETIVO: Verificar a freqüência do comprometimento da mucosa oral em pacientes de hanseníase multibacilar. CASUÍSTICA E MÉTODOS: Foi realizado um estudo transversal em vinte pacientes de hanseníase multibacilar, não-tratados, atendidos consecutivamente em Dracena, São Paulo, entre o período de 2000 e 2002. Foi realizado exame clínico completo da mucosa oral. Os pacientes foram submetidos a biópsias na mucosa jugal, na língua e no palato mole, em alteração ou em pontos pré-estabelecidos. Os cortes foram corados pelas técnicas da hematoxilina-eosina e Ziehl-Neelsen. O encontro de granuloma e bacilos álcool-ácido-resistentes ao exame histopatológico determinou o comprometimento específico. RESULTADOS: O estudo envolveu 19 pacientes multibacilares com tempo médio de evolução de 2,5 anos. Ocorreu comprometimento histopatológico específico em apenas um paciente virchowiano, com mucosa oral clinicamente normal, na língua e no palato mole. CONCLUSÕES: 1. Alteração clínica na mucosa oral não implica em comprometimento pela doença, é necessário confirmação histopatológica. 2. Alterações clínicas específicas aparentes são raras. 3.

    Full Text Available BACKGROUND: With 249,007 new leprosy patients detected globally in 2008, it remains necessary to develop new and effective interventions to interrupt the transmission of M. leprae. We assessed the economic benefits of single dose rifampicin (SDR for contacts as chemoprophylactic intervention in the control of leprosy. METHODS: We conducted a single centre, double blind, cluster randomised, placebo controlled trial in northwest Bangladesh between 2002 and 2007, including 21,711 close contacts of 1,037 patients with newly diagnosed leprosy. We gave a single dose of rifampicin or placebo to close contacts, with follow-up for four years. The main outcome measure was the development of clinical leprosy. We assessed the cost effectiveness by calculating the incremental cost effectiveness ratio (ICER between the standard multidrug therapy (MDT program with the additional chemoprophylaxis intervention versus the standard MDT program only. The ICER was expressed in US dollars per prevented leprosy case. FINDINGS: Chemoprophylaxis with SDR for preventing leprosy among contacts of leprosy patients is cost-effective at all contact levels and thereby a cost-effective prevention strategy. In total, $6,009 incremental cost was invested and 38 incremental leprosy cases were prevented, resulting in an ICER of $158 per one additional prevented leprosy case. It was the most cost-effective in neighbours of neighbours and social contacts (ICER $214, slightly less cost-effective in next door neighbours (ICER $497 and least cost-effective among household contacts (ICER $856. CONCLUSION: Chemoprophylaxis with single dose rifampicin given to contacts of newly diagnosed leprosy patients is a cost-effective intervention strategy. Implementation studies are necessary to establish whether this intervention is acceptable and feasible in other leprosy endemic areas of the world.

    Leprosy has a wide range of clinical and socio-economic consequences. India, Indonesia and Nepal contribute significantly to the global leprosy burden. After integration, the health systems are pivotal in leprosy service delivery. The Leprosy Post Exposure Prophylaxis (LPEP) program is ongoing to investigate the feasibility of providing single dose rifampicin (SDR) as post-exposure prophylaxis (PEP) to the contacts of leprosy cases in various health systems. We aim to compare national leprosy control programs, and adapted LPEP strategies in India, Nepal and Indonesia. The purpose is to establish a baseline of the health system's situation and document the subsequent adjustment of LPEP, which will provide the context for interpreting the LPEP results in future. The study followed the multiple-case study design with single units of analysis. The data collection methods were direct observation, in-depth interviews and desk review. The study was divided into two phases, i.e. review of national leprosy programs and description of the LPEP program. The comparative analysis was performed using the WHO health system frameworks (2007). In all countries leprosy services including contact tracing is integrated into the health systems. The LPEP program is fully integrated into the established national leprosy programs, with SDR and increased documentation, which need major additions to standard procedures. PEP administration was widely perceived as well manageable, but the additional LPEP data collection was reported to increase workload in the first year. The findings of our study led to the recommendation that field-based leprosy research programs should keep health systems in focus. The national leprosy programs are diverse in terms of organizational hierarchy, human resource quantity and capacity. We conclude that PEP can be integrated into different health systems without major structural and personal changes, but provisions are necessary for the additional monitoring

    Full Text Available Leprosy is a major public health problem in many low and middle income countries, especially in India, and contributes considerably to the global burden of the disease. Leprosy and poverty are closely associated, and therefore the economic burden of leprosy is a concern. However, evidence on patient's expenditure is scarce. In this study, we estimate the expenditure in primary care (outpatient by leprosy households in two different public health settings.We performed a cross-sectional study, comparing the Union Territory of Dadra and Nagar Haveli with the Umbergaon block of Valsad, Gujrat, India. A household (HH survey was conducted between May and October, 2016. We calculated direct and indirect expenditure by zero inflated negative binomial and negative binomial regression.

The age of the leprosy patients and type of health facilities were the major predictors of total expenditure on leprosy primary care. The higher the age, the higher the expenditure at both sites. The private facilities are more expensive than the government facilities at both sites. If the public health system is enhanced, government facilities are the first preference for patients.An enhanced public health system reduces the patient's expenditure and improves the health seeking behaviour. We recommend investing in health system strengthening to reduce the economic burden of leprosy.

    Full Text Available In leprosy, classic diagnostic tools based on bacillary counts and histopathology have been facing hurdles, especially in distinguishing latent infection from active disease and diagnosing paucibacillary clinical forms. Serological tests and IFN-gamma releasing assays (IGRA that employ humoral and cellular immune parameters, respectively, are also being used, but recent results indicate that quantitative PCR (qPCR is a key technique due to its higher sensitivity and specificity. In fact, advances concerning the structure and function of the Mycobacterium leprae genome led to the development of specific PCR-based gene amplification assays for leprosy diagnosis and monitoring of household contacts. Also, based on the validation of point-of-care technologies for M. tuberculosis DNA detection, it is clear that the same advantages of rapid DNA detection could be observed in respect to leprosy. So far, PCR has proven useful in the determination of transmission routes, M. leprae viability, and drug resistance in leprosy. However, PCR has been ascertained to be especially valuable in diagnosing difficult cases like pure neural leprosy (PNL, paucibacillary (PB, and patients with atypical clinical presentation and histopathological features compatible with leprosy. Also, the detection of M. leprae DNA in different samples of the household contacts of leprosy patients is very promising. Although a positive PCR result is not sufficient to establish a causal relationship with disease outcome, quantitation provided by qPCR is clearly capable of indicating increased risk of developing the disease and could alert clinicians to follow these contacts more closely or even define rules for chemoprophylaxis.

    To understand the situation of child leprosy patients in the low prevalence situation pertaining in China. A retrospective survey by questionnaire was carried out in all 32 provinces of mainland of China in 2011. All data concerning child cases detected from January 2005 to December 2009 were collected by professional health workers working at county level. During the study, only 165 questionnaires were collected for analysis. Among 165 child cases, 96 were boys, 69 were girls with an average age of 11-7 years old. 80% of child cases were members of families with other leprosy affected people. 145 (85%) child cases took their MDT secretly (nobody outside the family knew the child suffered from leprosy), and three (1.8%) children died, one each from dapsone syndrome, suicide and severe pneumonia. During follow-up, four child cases developed new disability increasing the Grade 2 disability rate to 13.3% (22/165). At end of the study, 8.2% of children had discontinued their study at school, and 7.5% had moved to a remote place to do casual work, while 6.3% stayed at home. 31% of child patients thought that leprosy caused a negative impact on their daily life. Two children had a hostile attitude toward society due to the stigma caused by leprosy. In both high and low endemic areas, as long as there is an infectious source of leprosy in the family, there is a possibility for children to develop leprosy. Contact surveys should be done to detect early disease, especially when there are children in the household.

    This study looked at the integration of leprosy services in the GHS in context of health and socioeconomic situations using predefined indicators. It also looked at clients' perception of MDT services. The Indian states of Chhattisgarh and Kerala, which are at two extremes in leprosy endemicity, health situation and socioeconomic development, have been compared using predefined integration indicators related to the training of health workers, availability of MDT services, maintenance of MDT stock and involvement of Sub-centres in leprosy care. Data was collected by surveys of health facilities, sub-centres and communities in the two states, during 2006-2007. Information was collected by interviewing health personnel and clients, checking of records and on the spot observations using specifically designed formats. Results showed that integration is more inclusive in Chhattisgarh and has reached up to Sub-centre level. Both the community and health systems are sensitive and responsive to leprosy as it is perceived to be a major public health threat. But in Kerala, despite integration, it continues as a vertical programme with dependence on specialists and districts hospitals for diagnosis and treatment. MDT stock management is even poorer. Clients' perception towards MDT services are similar in both states.

    Polymorphisms present in the TNF promoter region has shown to influence the gene transcription. Leprosy displays different clinical manifestations according to the immune responses of the individual infected with Mycobacterium leprae. In this study, we evaluated the single nucleotide polymorphisms (SNPs) -238 G/A (rs361525), -308 G/A (rs1800629), -857 C/T (rs1799724), -863 A/C (rs1800630) and -1031 T/C (rs1799964) in the promoter region of the TNF to see whether these SNPs influence host-susceptibility to leprosy and the different clinical manifestation. Nucleotide sequencing was performed with DNA samples from 108 leprosy patients and 253 control subjects. An association between -1031 C/C genotype and protection from leprosy was observed when leprosy patients were compared to controls (OR 0.11; 95% CI=0.01-0.82; p=0.012). The -857 C/T genotype may be associated with susceptibility to leprosy (OR=1.81; 95% CI=1.09-3.00; p=0.028). Similar genotype and allele frequencies for the SNPs -308 G/A and -238 G/A were observed between leprosy patients and control subjects. Altogether, TNF polymorphisms in the promoter region may be predictive of leprosy outcome. Copyright © 2015 American Society for Histocompatibility and Immunogenetics. Published by Elsevier Inc.

    Full Text Available In Brazil, leprosy is endemic and concentrated in high-risk clusters. Internal migration is common in the country and may influence leprosy transmission and hamper control efforts. We performed a cross-sectional study with two separate analyses evaluating factors associated with migration in Brazil’s Northeast: one among individuals newly diagnosed with leprosy and the other among a clinically unapparent population with no symptoms of leprosy for comparison. We included 394 individuals newly diagnosed with leprosy and 391 from the clinically unapparent population. Of those with leprosy, 258 (65.5% were birth migrants, 105 (26.6% were past five-year migrants, and 43 (10.9% were circular migrants. In multivariate logistic regression, three independent factors were found to be significantly associated with migration among those with leprosy: (1 alcohol consumption, (2 separation from family/friends, and (3 difficulty reaching the healthcare facility. Separation from family/friends was also associated with migration in the clinically unapparent population. The health sector may consider adapting services to meet the needs of migrating populations. Future research is needed to explore risks associated with leprosy susceptibility from life stressors, such as separation from family and friends, access to healthcare facilities, and alcohol consumption to establish causal relationships.

    Currently, leprosy control relies on the clinical diagnosis of leprosy and the subsequent administration of multidrug therapy (MDT). However, many health workers are not familiar with the cardinal signs of leprosy, particularly in low-endemic settings including Cambodia. In response, a new approach to early diagnosis was developed in the country, namely retrospective active case finding (RACF) through small mobile teams. In the frame of RACF, previously diagnosed leprosy patients are traced and their contacts screened through "drives". According to the available records, 984 of the 1,463 (67.3%) index patients diagnosed between 2001 and 2010 and registered in the national leprosy database were successfully traced in the period 2012-2015. Migration (8.4%), death (6.7%), operational issues (1.6%) and unidentified other issues (16.0%) were the main reasons for non-traceability. A total of 17,134 contacts of traced index patients (average: 2.2 household members and 15.2 neighbors) and another 7,469 contacts of the untraced index patients could be screened. Among them, 264 new leprosy patients were diagnosed. In the same period, 1,097 patients were diagnosed through the routine passive case detection system. No change was observed in the relation between the rate at which new patients were identified and the number of years since the diagnosis of the index patient. Similar to leprosy patients diagnosed through passive case detection, the leprosy patients detected through RACF were predominantly adult males. However, the fraction of PB leprosy patients was higher among the patients diagnosed through RACF, suggesting relatively earlier diagnosis. It appears that RACF is a feasible option and effective in detecting new leprosy patients among contacts of previously registered patients. However, a well-maintained national leprosy database is essential for successful contact tracing. Hence, passive case detection in the frame of routine leprosy surveillance is a precondition

    >94% of new annual leprosy cases are diagnosed in populations co-endemic for soil-transmitted helminths (STH). STH can profoundly dysregulate host immune responses towards Th2 bias, which can be restored over time after deworming. We hypothesize that STH co-infection is associated with leprosy reaction (denoted as simply "reaction" herein) occurrence within a co-endemic population. A cohort study was performed on a cohort of Nepalese leprosy patients across treatment and diagnostic classifications who were screened by routine fecal smear microscopy and multiplex quantitative PCR (qPCR) for Ascaris lumbricoides (Al), Strongyloides stercoralis (Ss), Ancyclostoma duodenale (Ad) and Necator americanus (Na). Among 145 patients, 55% were positive for ≥1 STH (STH+): 34% Al+, 18% Ss+, 17% Ad+and 5% Na+. Significant inverse STH and reaction relationships were evidenced by the bulk of cases: 63% reaction-negative were STH+ of total cases (p=0.030) while 65% reaction-positive were STH- in new cases (96; p=0.023). Strikingly, the majority of STH+ were reaction-negative, even when considering each species: 59% Al+, 60% Ss+, 62% Ad+and 67% Na+of new leprosy cases. Absence of STH co-infection is associated with leprosy reaction at diagnosis within a co-endemic population. This is likely due to immune reconstitution effects after deworming or interruption of chronic STH-mediated immune dysregulation. Copyright © 2017. Published by Elsevier B.V.

    2018-01-01

    Background Leprosy is a condition that has long been associated with stigma and discrimination, even when infected persons have been cured. This paper describes stigma and discrimination as viewed by caregivers who are associated with people affected by leprosy in Ghana. Methods A qualitative interview with semi-structured interviews were conducted for twenty caregivers. Results Findings indicated that caregivers were of the view that people affected by leprosy in Ghana are stigmatized and discriminated against by the larger society thus making their movements and interactions restricted to the Leprosarium. Besides, employments opportunities are unavailable to them thus making them exposed to financial challenges. The livelihood Empowerment Against poverty (LEAP) money given them is not sufficient for their daily upkeep. Conclusion People affected by leprosy in Ghana are stigmatized and therefore find it difficult to interact freely with the public. The associated physical deformities with the disease also tend to impede their ability to relate to the general public. The LEAP cash given to people affected by leprosy is helpful however, it could be enhanced to keep pace with prevailing economic conditions in the country. PMID:29377890

    BACKGROUND Leprosy is an infectious disease caused by Mycobacterium leprae, able to infect large numbers of people. This work is relevant to Juazeiro-BA, a hyper-endemic area for leprosy, since unravel the behavior of the disease in the area, may suggest the decision making for sectors of surveillance, establishing strategies, organizing and evaluating programs and services. OBJECTIVES To analyze the epidemiology of leprosy in Juazeiro-BA, from 2002 to 2012. METHODS A descriptive, cross-sectional study was conducted based in data of the Diseases Notification System, assigned by the service of Epidemiology from Juazeiro-BA, between 2002 and 2012. RESULTS 1,916 new cases of leprosy were detected between 2002 and 2012, of which 921 (48.07%) represented male sex, 995 (51.93%) female, and there was a reduction in the incidence rate of leprosy per 100,000 inhabitants. Most carriers were brown individuals, with low levels of education, living in the urban area, being more prevalent in the economically active age group. Through statistical analysis we found that there are more chances of developing sequelae among men, and multibacillary individuals older than 45 years. CONCLUSIONS The work serves to direct efforts to control this disease, and highlights the importance of active search for new cases to achieve an early diagnosis, reducing the number of sequels and allowing breaking the chain of disease transmission.

    2010-12-01

    This paper reviews the 13-year evolution of the social economic activities in Northern Nigeria from a welfare-oriented to a community-centred programme for people affected by leprosy. The review relied on the analysis of policy and strategy documents, programme guidelines and statistical and evaluation reports. Findings revealed that the transformation among other things, demanded formulation of new programme policies and guidelines; and staff training in CBR principles and practice. Findings also showed that adopting CBR principles and community development projects can stimulate improvements in living conditions, self-esteem and acceptance of people affected by leprosy into the community. Regardless of becoming a more inclusive and participatory programme wherein people affected by leprosy contribute to programme implementation and evaluation; groups affected by leprosy remain economically dependent on the programme and partnership mobilisation is weak. This explains why the priorities for sustaining the processes and impacts generated through CBR in northern Nigeria include: i) empowering groups to access mainline services; ii) working through partners to implement CBR and attract extra funding/ownership of interventions, and iii) promoting human rights of people affected by leprosy and working for a barrier free environment. In the absence of an agreeable understanding and method of assessing sustainability in CBR, we recommend the field-testing of a proposal for evaluating sustainability, to determine its utility in different contexts. Such field-tests have the potential of influencing policy and practice in the future.

  13. Oral health conditions in leprosy cases in hyperendemic area of the Brazilian Amazon

    Full Text Available ABSTRACT Leprosy is a hyperendemic chronic condition in the Rondônia State . Despite the significant impact of oral health on the quality of life and clinical evolution of leprosy patients, systematic evaluation of oral health status has been neglected. To analyze the dental-clinical profile, self-perceived oral health and dental health service access of leprosy cases in the municipality of Cacoal in Rondônia State , North Brazil, from 2001 to 2012. A descriptive, cross-sectional study design was performed based on dental evaluation and standardized structured instruments. We investigated clinically assessed and self-perceived oral health status, as well as dental health service access. A total of 303 leprosy cases were included; 41.6% rated their oral health as good, and 42.6% reported being satisfied with their oral health. Self-reported loss of upper teeth was 45.5%. The clinical evaluation revealed that 54.5% had active caries. Most (97.7% cases reported having been to the dentist at least once in their life and 23.1% used public health services. The poor standard of oral health in this population may increase the risk for leprosy reactions, consequently reducing quality of life. Low access to public health dental services and poor self-perceived oral health reinforce the need to achieve comprehensive health care in this population.

    1989-01-01

    Full Text Available Effectiveness of community-based leprosy control operations spanning almost a decade in two locations, a small self settled leprosy colony (I of about 800 subjects as well as a large slum (II with a population of about 20,000 in the metropolitan city of Bombay are compared. New case detection through survey in location I and voluntary reporting in location II during the period 1982-86 is taken as an index of the impact of the intervention, which consisted of field based administration of multi-drug therapy. Though the leprosy colony concentrates an abnormal reservoir of infectious cases in a small population, it was relatively easier to achieve success in reducing the transmission rate through field-based chemotherapy programme. The same degree of success however, could not be achieved in a normal slum. Health care delivery system in relation to leprosy eradication at the grass-root levels has to be planned giving maximum importance to cost-effective methods of identification of multi-bacillary leprosy patients and monitoring their movements carefully during the treatment phase.

    To review all notified cases of leprosy in England and Wales between 1953 and 2012. National surveillance study of all reported cases. England and Wales. Number and characteristics of reported cases. During this period, a total of 1449 leprosy cases were notified. The incidence fell from 356 new cases notified between 1953 and 1962 to 139 new cases between 2003 and 2012. Where data were available, leprosy was more common in men, 15-45 year olds and those from the Indian subcontinent. There was considerable undernotification in 2001-2012. The high level of under-reporting indicates a need for improved surveillance in the UK. Public Health England, in collaboration with the UK Panel of Leprosy opinion, has revised the UK Memorandum on Leprosy in order to provide updated guidance on diagnostic procedures, treatment, case management, contact tracing and notification.

    Leprosis refers to two diseases of citrus that present similar necrotic local lesions, often surrounded by chlorotic haloes on citrus. Two distinct viruses are associated with this disease, one that produces particles primarily in the nucleus of infected plant cells (Citrus leprosis virus nuclear type [CiLV-N]; Dichorhavirus) and another type that produces particles in the cytoplasm of infected plant cells (Citrus leprosis virus cytoplasmic type [CiLV-C]; Cilevirus). Both forms are transmitted by Brevipalpid mites and have bipartite, single-stranded, RNA genomes. CiLV-C and CiLV-N are present in South and Central America and as far north as parts of Mexico. Although leprosis disease was originally described from Florida, it disappeared from there in the 1960s. The United States Department of Agriculture-Agricultural Research Service maintains preserved citrus specimens identified at inspection stations 50 or more years ago with symptoms of citrus leprosis. We isolated RNA from these samples and performed degradome sequencing. We obtained nearly full-length genome sequences of both a typical CiLV-C isolate intercepted from Argentina in 1967 and a distinct CiLV-N isolate obtained in Florida in 1948. The latter is a novel form of CiLV-N, not known to exist anywhere in the world today. We have also documented the previously unreported presence of CiLV-N in Mexico in the mid-20th century.

    In leprosy, oral health is often neglected and poorly understood. This study aimed to evaluate the prevalence and risk indicators of dental caries in patients with leprosy in China. This cross-sectional, multicentre study included 613 patients with leprosy and 602 control subjects. Based on the established standards of the World Health Organization, we investigated dental caries in cluster samplings from six so-called 'leprosy villages' in three Chinese provinces. Clinical oral examinations were performed and data were reported as decayed (D), missing (M) and filled (F) teeth (DMFT scores). The average DMFT scores were 10.39 in patients with leprosy (D = 4.43; M = 5.94; and F = 0.02) and 4.39 in control individuals (D = 2.29; M = 2.02; F = 0.08). The DMFT scores were statistically significantly different in patients with different ages, educational backgrounds and daily brushing frequency (P caries. Effective therapy and oral health education should be enhanced for this group of patients. © 2016 The Authors.

    Full Text Available Geospatial methods were used to study the associations of the environmental thermal-hydrological regime with leprosy prevalence in the Oromia and Amhara regions of Ethiopia. Prediction models were developed that indicated leprosy prevalence was related to: (i long-term normal climate grid data on temperature and moisture balance (rain/potential evapo-transpiration; (ii satellite surveillance data on the Normalized Difference Vegetation Index (NDVI and daytime earth surface temperature (Tmax from the Advanced Very High Resolution Radiometer (AVHRR; and (iii a Genetic Algorithm Rule-Set Prediction (GARP model based on NDVI and Tmax data in relation to leprosy prevalence data. Our results suggest that vertical transmission is not the only means of acquiring leprosy and support earlier reports that a major factor that governs transmission of leprosy is the viability of Mycobacterium leprae outside the human body which is related to the thermal-hydrologic regime of the environment.

    Full Text Available Social determinants can affect the transmission of leprosy and its progression to disease. Not much is known about the effectiveness of welfare and primary health care policies on the reduction of leprosy occurrence. The aim of this study is to evaluate the impact of the Brazilian cash transfer (Bolsa Família Program-BFP and primary health care (Family Health Program-FHP programs on new case detection rate of leprosy.We conducted the study with a mixed ecological design, a combination of an ecological multiple-group and time-trend design in the period 2004-2011 with the Brazilian municipalities as unit of analysis. The main independent variables were the BFP and FHP coverage at the municipal level and the outcome was new case detection rate of leprosy. Leprosy new cases, BFP and FHP coverage, population and other relevant socio-demographic covariates were obtained from national databases. We used fixed-effects negative binomial models for panel data adjusted for relevant socio-demographic covariates. A total of 1,358 municipalities were included in the analysis. In the studied period, while the municipal coverage of BFP and FHP increased, the new case detection rate of leprosy decreased. Leprosy new case detection rate was significantly reduced in municipalities with consolidated BFP coverage (Risk Ratio 0.79; 95% CI  =0.74-0.83 and significantly increased in municipalities with FHP coverage in the medium (72-95% (Risk Ratio 1.05; 95% CI  =1.02-1.09 and higher coverage tertiles (>95% (Risk Ratio 1.12; 95% CI  =1.08-1.17.At the same time the Family Health Program had been effective in increasing the new case detection rate of leprosy in Brazil, the Bolsa Família Program was associated with a reduction of the new case detection rate of leprosy that we propose reflects a reduction in leprosy incidence.

    When British attention was drawn to the issue of leprosy in the Empire, humanitarian organisations rose to take on responsibility for the 'fight against leprosy'. In an effort to fundraise for a distant cause at a time when hundreds of charities competed for the financial support of British citizens, fundraisers developed propaganda to set leprosy apart from all other humanitarian causes. They drew on leprosy's relationship with Christianity, its debilitating symptoms, and the supposed vulnerability of leprosy sufferers in order to mobilise Britain's sense of humanitarian, Christian, and patriotic duty. This article traces the emergence of leprosy as a popular imperial humanitarian cause in modern Britain and analyses the narratives of religion, suffering, and disease that they created and employed in order to fuel their growth and sell leprosy as a British humanitarian cause.

    A handy device for testing the thermal sensibility of skin lesions has been developed and field tested in various centres in Africa and India. The instrument performed satisfactorily and its use made testing for thermal sensibility in the field practicable and straightforward. Analysis of the results of testing 260 persons, most of whom exhibited a few lesions that were characteristic of early leprosy, showed that the rate of diagnosis of sensory impairment of such skin lesions, and hence the diagnosis of leprosy, would be about 15-25% more if thermal sensibility testing using this device were added to the other tests of sensibility routinely carried out in the field. Regular use of the device in the field would help to bring more leprosy patients under treatment than at present. Images Fig. 5 PMID:2699276

    2018-01-01

    This study explored experiences of courtesy stigma among caregivers of people affected by leprosy. Using a qualitative research approach, twenty participants were purposively selected and in-depth interviews conducted. The interviews were audio-recorded, transcribed, and analyzed to identify emerging themes that addressed objectives of the study. The findings indicated that caregivers of people affected by leprosy experienced courtesy stigma. Evidence showed that fear of contagion underpinned caregivers' experiences, especially in employment and romantic relationships. In addition, participants adopted different strategies (disregarding, concealment, education, faith-based trust) to handle courtesy stigma. The findings demonstrate that psychosocial support and financial assistance to caregivers are necessary considerations for attainment of effective care for people affected by leprosy.

    This study aims to assess the oxidative stress in leprosy patients under multidrug therapy (MDT; dapsone, clofazimine and rifampicin), evaluating the nitric oxide (NO) concentration, catalase (CAT) and superoxide dismutase (SOD) activities, glutathione (GSH) levels, total antioxidant capacity, lipid peroxidation, and methemoglobin formation. For this, we analyzed 23 leprosy patients and 20 healthy individuals from the Amazon region, Brazil, aged between 20 and 45 years. Blood sampling enabled the evaluation of leprosy patients prior to starting multidrug therapy (called MDT 0) and until the third month of multidrug therapy (MDT 3). With regard to dapsone (DDS) plasma levels, we showed that there was no statistical difference in drug plasma levels between multibacillary (0.518±0.029 µg/mL) and paucibacillary (0.662±0.123 µg/mL) patients. The methemoglobin levels and numbers of Heinz bodies were significantly enhanced after the third MDT-supervised dose, but this treatment did not significantly change the lipid peroxidation and NO levels in these leprosy patients. In addition, CAT activity was significantly reduced in MDT-treated leprosy patients, while GSH content was increased in these patients. However, SOD and Trolox equivalent antioxidant capacity levels were similar in patients with and without treatment. These data suggest that MDT can reduce the activity of some antioxidant enzyme and influence ROS accumulation, which may induce hematological changes, such as methemoglobinemia in patients with leprosy. We also explored some redox mechanisms associated with DDS and its main oxidative metabolite DDS-NHOH and we explored the possible binding of DDS to the active site of CYP2C19 with the aid of molecular modeling software.

    Full Text Available A national sample survey of leprosy was undertaken in partnership with Indian Council of Medical Research (ICMR institutions, National Leprosy Eradication Programme (NLEP, Panchayati Raj members, and treated leprosy patients to detect new cases of leprosy in India. The objectives of the survey were to estimate the new leprosy case load; record both Grade 1 and Grade 2 disabilities in the new cases; and to assess the magnitude of stigma and discrimination prevalent in the society. A cluster based, cross-sectional survey involving all States was used for the door-to-door survey using inverse sampling methodology. Rural and urban clusters were sampled separately. The population screened for detecting 28 new cases in rural and 30 in urban clusters was enumerated, recorded and analyzed. Data capture and analysis in different schedules were the main tools used. For quality control three tiers of experts were utilized for the confirmation of cases and disabilities. Self-stigma was assessed in more than half of the total new patients detected with disabilities by the approved questionnaire. A different questionnaire was used to assess the stigma in the community. A population of 14,725,525 (10,302,443 rural; 4,423,082 urban was screened and 2161 new cases - 1300 paucibacillary (PB and 861 multibacillary (MB were detected. New case estimates for leprosy was 330,346 (95% Confidence limits, 287,445-380,851. Disabilities observed in these cases were 2.05/100,000 population and 13.9 per cent (302/2161 in new cases. Self-stigma in patients with disabilities was reduced, and the patients were well accepted by the spouse, neighbour, at workplace and in social functions.

  7. Imaging the trigeminal nerve

    Of all cranial nerves, the trigeminal nerve is the largest and the most widely distributed in the supra-hyoid neck. It provides sensory input from the face and motor innervation to the muscles of mastication. In order to adequately image the full course of the trigeminal nerve and its main branches a detailed knowledge of neuroanatomy and imaging technique is required. Although the main trunk of the trigeminal nerve is consistently seen on conventional brain studies, high-resolution tailored imaging is mandatory to depict smaller nerve branches and subtle pathologic processes. Increasing developments in imaging technique made possible isotropic sub-milimetric images and curved reconstructions of cranial nerves and their branches and led to an increasing recognition of symptomatic trigeminal neuropathies. Whereas MRI has a higher diagnostic yield in patients with trigeminal neuropathy, CT is still required to demonstrate the bony anatomy of the skull base and is the modality of choice in the context of traumatic injury to the nerve. Imaging of the trigeminal nerve is particularly cumbersome as its long course from the brainstem nuclei to the peripheral branches and its rich anastomotic network impede, in most cases, a topographic approach. Therefore, except in cases of classic trigeminal neuralgia, in which imaging studies can be tailored to the root entry zone, the full course of the trigeminal nerve has to be imaged. This article provides an update in the most recent advances on MR imaging technique and a segmental imaging approach to the most common pathologic processes affecting the trigeminal nerve.

    Leprosy is a chronic human disease caused by the yet-uncultured pathogen Mycobacterium leprae. Although readily curable with multidrug therapy (MDT), over 200,000 new cases are still reported annually. Here, we obtain M. leprae genome sequences from DNA extracted directly from patients' skin biopsies using a customized protocol. Comparative and phylogenetic analysis of 154 genomes from 25 countries provides insight into evolution and antimicrobial resistance, uncovering lineages and phylogeographic trends, with the most ancestral strains linked to the Far East. In addition to known MDT-resistance mutations, we detect other mutations associated with antibiotic resistance, and retrace a potential stepwise emergence of extensive drug resistance in the pre-MDT era. Some of the previously undescribed mutations occur in genes that are apparently subject to positive selection, and two of these (ribD, fadD9) are restricted to drug-resistant strains. Finally, nonsense mutations in the nth excision repair gene are associated with greater sequence diversity and drug resistance.

    Full Text Available Acute phase reactants i. e. ESR, C-reactive proteins, alpha 1 antitrypsin, complement (C3 and circulation immune complexes were evaluated in relation with the activity of the disease in leprosy. Levels of all the acute phase reactants were significantly raised during the active plase (LL and ENL, while these were normal during the arrested phase of the disease. Appearance of, circulating immune complexes also followed the same pattern. It is concluded that raised levels of ESR (C-reactive proteins, alpha-1 antitrypsin, complement (C3 and circulating immune complexes suggest active phase (LL ENL of the disease in leprosy.

    Full Text Available Abstract INTRODUCTION: We aimed to investigate the feasibility of assistive technology (AT devices to improve leprosy patients' occupational performances and satisfaction. METHODS: This is a pretest-posttest design study. The Canadian Occupational Performance Measure was used to assess the occupational performance and satisfaction of five leprosy participants with grade 2 disabilities before and after ten 45-minute interventions using assistive technology devices. RESULTS: The data showed a statistically significant 7-point average improvement (p<0.05 in participants' post-intervention performance and satisfaction scores. CONCLUSIONS: Assistive technology devices may be useful therapeutic tools to enhance autonomy/independence and satisfaction of leprosy patients with grade 2 disabilities.

    The exact mode of transmission of leprosy is not clearly understood; however, many studies have demonstrated active transmission of leprosy around a source case. Families of five active leprosy cases and their household contacts were chosen from a high endemic area in Purulia. Fifty-two soil samples were also collected from different areas of their houses. DNA was extracted from slit-skin smears (SSS) and soil samples and the Mycobacterium leprae-specific RLEP (129 bp) region was amplified using PCR. Molecular typing of M. leprae was performed for all RLEP PCR-positive samples by single nucleotide polymorphism (SNP) typing and confirmation by DNA sequencing. SSS of these five patients and six out of the total 28 contacts were PCR positive for RLEP whereas 17 soil samples out of 52 showed the presence of M. leprae DNA. SNP typing of M. leprae from all RLEP PCR-positive subjects (patients and smear-positive contacts) and 10 soil samples showed the SNP type 1 genotype. M. leprae DNA from the five leprosy patients and the six contacts was further subtyped and the D subtype was noted in all patients and contacts, except for one contact where the C subtype was identified. Typing followed by subtyping of M. leprae clearly revealed that either the contacts were infected by the patients or both patients and contacts had the same source of infection. It also revealed that the type of M. leprae in the soil in the inhabited areas where patients resided was also of the same type as that found in patients. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

  14. Begotten of Corruption? Bioarchaeology and "othering" of leprosy in South Asia.

    2016-12-01

    Leprosy is strongly stigmatized in South Asia, being regarded as a manifestation of extreme levels of spiritual pollution going back through one or more incarnations of the self. Stigma has significant social consequences, including surveillance, exclusion, discipline, control, and punishment; biologically speaking, internalized stigma also compounds the disfigurement and disability resulting from this disease. Stigma results from an othering process whereby difference is recognized, meaning is constituted, and eventually, sufferers may be negatively signified and marked for exclusion. This paper traces the history of leprosy's stigmatization in South Asia, using archaeology and an exegesis of Vedic texts to examine the meaning of this disease from its apparent zero-point-when it first appears but before it was differentiated and signified-in the mature Indus Age. Results suggest that early in the second millennium BCE, leprosy was perceived as treatable and efforts were apparently made to mitigate its impact on the journey to the afterworld. Ignominy to the point of exclusion does not emerge until the first millennium BCE. This paper uses archaeology to create an effective history of stigma for leprosy, destabilizing what is true about this disease and its sufferers in South Asia today. Copyright © 2016 Elsevier Inc.

    2016-01-01

    Full Text Available Aim: After the introduction of the multidrug therapy, the incidence of leprosy is decreasing every year. However, periodontal complaints are commonly seen in these patients due to compromised immunity and impaired oral hygiene. The aim of the present study is to assess the oral and periodontal status of the leprosy patients in Dindigul district. Materials and Methods: The study was conducted on 62 patients treated in a leprosy center at Dindigul district. Among these, 22 (35.5% were female patients and 40 were male patients (64.5%. Age ranges between 40 and 70 with the mean age being 52. Facial changes, periodontal status, dental caries, attrition, tooth loss, plaque index (Silness and Loe, and calculus component of oral hygiene index-simplified were assessed. Results: Majority of the patients presented with loss of eyebrows and eyelashes, saddle nose, ocular involvement, and leonine facies. Gingival recession (54.8% was a predominant finding followed by tooth loss (69.5%, mobility (60.86%, attrition (56%, chronic pulpitis (34.7%, and dental caries (26%. Most of the patients had severe periodontitis. Conclusions: Compromised immunity and altered autonomy pave way for many dental complaints such as periodontitis and deposits in tooth with poor oral hygiene. Awareness about the oral health problems and reinforcement of oral hygiene should be insisted to the leprosy patients to prevent further morbidity.

    Full Text Available Persons affected by leprosy or by disabilities face forms of stigma that have an impact on their lives. This study seeks to establish whether their experiences of stigma are similar, with a view to enabling the two groups of people to learn from each other. Accounts of experiences of the impact of stigma were obtained using in-depth interviews and focus group discussion with people affected by leprosy and by disabilities not related to leprosy. The analysis shows that there are a lot of similarities in impact of stigma in terms of emotions, thoughts, behaviour, and relationships between the two groups. The main difference is that those affected by leprosy tended to frame their situation in medical terms, while those living with disabilities described their situation from a more social perspective. In conclusion, the similarities offer opportunities for interventions and the positive attitudes and behaviours can be modelled in the sense that both groups can learn and benefit. Research that tackles different aspects of stigmatization faced by both groups could lead to inclusive initiatives that help individuals to come to terms with the stigma and to advocate against exclusion and discrimination.

    Full Text Available Background: Leprosy, a chronic infectious disease presents a broad clinical spectrum that is correlated with the immunological response of the patient, mainly related to Th1/Th2 cells. IL-10 is a major cytokine produced by Th2 cells inhibits imunostimulatory cytokine produced by Th1 cells. Suppressive effects of IL-10 in monocytes and cytokine synthesis by Th1 cells presumably because IL-10 has a general suppressive effect on immune function. Nigella sativa has a potent potentiating effect on cellular immunity through suppression of Th2 cells and IL-10, resulting in potentiation of Th1 cells. Method: The study design is a randomized pretest and posttest controlled design involving 40 subjects of MB leprosy patients. Serum levels of IL-10 were measured by ELISA. Result: The mean decrease in serum levels of IL-10 (IL-10 delta in the treatment group (average fell 3.12 pg/ml is greater than the control group (average rose 0.21 pg/ml, where the difference is statistically significant (p = 0.029. Nigella sativa giving significant correlation with a decrease in IL-10 compared to the control group (p=0.044, OR: 10.23. Conclusion: supplementation of Nigella sativa 3 x 1000 mg for 2 months in patients with MB leprosy can reduce levels of IL-10, thus increasing the cellular immune response in patients with MB leprosy.

    Full Text Available Leprosy is an infectious disease caused by the obligate intracellular pathogen Mycobacterium leprae and remains endemic in many parts of the world. Despite several major studies on susceptibility to leprosy, few genomic loci have been replicated independently. We have conducted an association analysis of more than 1,500 individuals from different case-control and family studies, and observed consistent associations between genetic variants in both TLR1 and the HLA-DRB1/DQA1 regions with susceptibility to leprosy (TLR1 I602S, case-control P = 5.7 x 10(-8, OR = 0.31, 95% CI = 0.20-0.48, and HLA-DQA1 rs1071630, case-control P = 4.9 x 10(-14, OR = 0.43, 95% CI = 0.35-0.54. The effect sizes of these associations suggest that TLR1 and HLA-DRB1/DQA1 are major susceptibility genes in susceptibility to leprosy. Further population differentiation analysis shows that the TLR1 locus is extremely differentiated. The protective dysfunctional 602S allele is rare in Africa but expands to become the dominant allele among individuals of European descent. This supports the hypothesis that this locus may be under selection from mycobacteria or other pathogens that are recognized by TLR1 and its co-receptors. These observations provide insight into the long standing host-pathogen relationship between human and mycobacteria and highlight the key role of the TLR pathway in infectious diseases.

    to identify the difficulties in diagnosing and treating neuropathic pain caused by leprosy and to understand the main characteristics of this situation. 85 patients were treated in outpatient units with reference to leprosy and the accompanying pain. We used a questionnaire known as the Douleur Neuropathic 4 test and we conducted detailed neurological exams. As a result, 42 patients were excluded from the study for not having proved their pain. Out of the 37 patients that experienced pain, 22 (59.5%) had neuropathic pain (or a mixture of this pain and their existing pain) and of these 90.8% considered this pain to be moderate or severe. 81.8% of the sample suffered with this pain for more than 6 months. Only 12 (54.5%) of the patients had been diagnosed with neuropathic pain and in almost half of these cases, this pain had not been diagnosed. With reference to medical treatment (n=12) for neuropathic pain, 5 (41.6%) responded that they became better. For the other 7 (58.4%) there were no changes in relation to the pain or in some cases the pain worsened in comparison to their previous state. Statistical analysis comparing improvements in relation to the pain amongst the patients that were treated (n=12) and those that were not, showed significant differences (value p=0.020). we noted difficulties in diagnosing neuropathic pain for leprosy in that almost half of the patients that were studied had not had their pain diagnosed. We attributed this to some factors such as the non-adoption of the appropriate protocols which led to inadequate diagnosis and treatment that overlooked the true picture. identificar as dificuldades em diagnosticar e tratar a dor neuropática causada pela hanseníase, bem como determinar as características principais dessa situação. examinaram-se 85 pacientes tratados no ambulatório de referência para hanseníase e referiam dor.

    Leprosy has been eliminated as a public health problem in most countries of the world according to the WHO, but the social stigma to the disease is still very high. The present study was performed to investigate the role of social stigma as a determinant for leprosy elimination in a leprosy endemic region of Cameroon. Focus group discussions, in-depth interviews and structured questionnaires were used to investigate leprosy social stigma among lepers, their contacts and a control group consisting of patients attending a health facility for reasons other than leprosy. Informed consent was sought and gained prior to starting the study. Focus group discussions and in-depth interviews identified three types of stigma: lack of self-esteem, tribal stigma and complete rejection by society. From the 480 structured questionnaires administered, there were overall positive attitudes to lepers among the study population and within the divisions (P=0.0). The proportion of participants that felt sympathetic with deformed lepers was 78.1% [95% confidence interval (CI): 74.4-81.8%] from a total of 480. Three hundred and ninety nine (83.1%) respondents indicated that they could share a meal or drink at the same table with a deformed leper (95% CI: 79.7-86.5%). Four hundred and three (83.9%) participants indicated that they could have a handshake and embrace a deformed leper (95% CI: 80.7-87.3%). A total of 85.2% (95.0% CI: 81.9-88.4%) participants affirmed that they could move with a deformed leper to the market or church. A high proportion of 71.5% (95.0% CI: 67.5%-75.5%) participants stated that they could offer a job to a deformed leper. The results indicate that Menchum division had the lowest mean score of 3.3 on positive attitudes to leprosy compared with Mezam (4.1) and Boyo (4.8) divisions. The high proportion of positive attitudes among the participants and in different divisions is a positive indicator that the elimination of leprosy social stigma is progressing in the

    Full Text Available INTRODUCTION: To analyze the knowledge, feelings and perceptions involving patients affected by leprosy, as a better understanding of these factors may be useful to decrease the stigma and prejudice associated with the condition. METHODS: The study cohort consisted of 94 patients who underwent treatment for leprosy at the Health Units in the City of Cuiabá, Mato Grosso (MT, Brazil. The study questionnaire included items to collect information on socio-demographic data, knowledge about the disease, stigma, prejudice, self-esteem and quality of life of leprosy patients. Bivariate analyses were used to assess the data based on the chi-square test with a 5% significance threshold. RESULTS: The results revealed that the study population consisted predominantly of males (55.3% with an income between 1 and 3 times the minimum wage (67%. The survey respondents reported that the most significant difficulties related to the treatment were the side effects (44.7% and the duration of the treatment (28.7%. A total of 72.3% of the subjects were knowledgeable about the disease, of whom 26.6% had the leprosy reaction. Stigma and prejudice were cited by 93.6% of the participants. Based on the responses, 40.4% of patients reported being depressed and sad, and 69.1% of the subjects encountered problems at work after being diagnosed. A total of 45.7% of the patients rated their quality of life between bad and very bad. CONCLUSIONS: Our results suggest that leprosy causes suffering in patients beyond pain and discomfort and greatly influences social participation.

  9. Experimental Infection of Rhodnius prolixus (Hemiptera, Triatominae with Mycobacterium leprae Indicates Potential for Leprosy Transmission.

    Directory of Open Access Journals (Sweden)

    Arthur da Silva Neumann

    Full Text Available Leprosy is a chronic dermato-neurological disease caused by infection with Mycobacterium leprae. In 2013 almost 200,000 new cases of leprosy were detected around the world. Since the first symptoms take from years to decades to appear, the total number of asymptomatic patients is impossible to predict. Although leprosy is one of the oldest records of human disease, the mechanisms involved with its transmission and epidemiology are still not completely understood. In the present work, we experimentally investigated the hypothesis that the mosquitoes Aedes aegypti and Culex quinquefasciatus and the hemiptera Rhodnius prolixus act as leprosy vectors. By means of real-time PCR quantification of M. leprae 16SrRNA, we found that M. leprae remained viable inside the digestive tract of Rhodnius prolixus for 20 days after oral infection. In contrast, in the gut of both mosquito species tested, we were not able to detect M. leprae RNA after a similar period of time. Inside the kissing bug Rhodnius prolixus digestive tract, M. leprae was initially restricted to the anterior midgut, but gradually moved towards the hindgut, in a time course reminiscent of the life cycle of Trypanosoma cruzi, a well-known pathogen transmitted by this insect. The maintenance of M. leprae infectivity inside the digestive tract of this kissing bug is further supported by successful mice footpad inoculation with feces collected 20 days after infection. We conclude that Rhodnius prolixus defecate infective M. leprae, justifying the evaluation of the presence of M. leprae among sylvatic and domestic kissing bugs in countries endemic for leprosy.

    Full Text Available Abstract INTRODUCTION Leprosy often results in sensory and physical limitations. This study aimed to evaluate these limitations using a quantitative approach in leprosy patients in Belém (Pará, Brazil. METHODS This epidemiological, cross-sectional study measured the sensory impairment of smell and taste through the use of a questionnaire and evaluated activity limitations of daily life imposed by leprosy through the Screening of Activity Limitation and Safety Awareness (SALSA Scale. Data were collected from 84 patients and associations between the degree of disability and clinical and epidemiological characteristics were assessed. RESULTS The majority of patients were men (64.3%, married (52.4%, age 31-40 years old (26.2%, had primary education (50%, and were independent laborers (36.9%. The multibacillary operational classification (81%, borderline clinical form (57.1%, and 0 degrees of physical disability (41.7% were predominant. SALSA scores ranged from 17 to 59 points, and being without limitations was predominant (53.6%. The risk awareness score ranged from 0 to 8, with a score of 0 (no awareness of risk being the most common (56%. Evaluation of smell and taste sensory sensitivities revealed that 70.2% did not experience these sensory changes. Patients with leprosy reactions were 7 times more likely to develop activity limitations, and those who had physical disabilities were approximately four times more likely to develop a clinical picture of activity limitations. CONCLUSIONS Most patients showed no sensory changes, but patients with leprosy reactions were significantly more likely to develop activity limitations. Finally, further studies should be performed, assessing a higher number of patients to confirm the present results.

A total of 45.7% of the patients rated their quality of life between bad and very bad. Our results suggest that leprosy causes suffering in patients beyond pain and discomfort and greatly influences social participation.

    Stigma negatively affects the quality of life of leprosy-affected people. Instruments are needed to assess levels of stigma and to monitor and evaluate stigma reduction interventions. We conducted a validation study of such instruments in Tamil Nadu and West Bengal, India. Four instruments were tested in a 'Community Based Rehabilitation' (CBR) setting, the Participation Scale, Internalised Scale of Mental Illness (ISMI) adapted for leprosy-affected persons, Explanatory Model Interview Catalogue (EMIC) for leprosy-affected and non-affected persons and the General Self-Efficacy (GSE) Scale. We evaluated the following components of validity, construct validity, internal consistency, test-retest reproducibility and reliability to distinguish between groups. Construct validity was tested by correlating instrument scores and by triangulating quantitative and qualitative findings. Reliability was evaluated by comparing levels of stigma among people affected by leprosy and community controls, and among affected people living in CBR project areas and those in non-CBR areas. For the Participation, ISMI and EMIC scores significant differences were observed between those affected by leprosy and those not affected (p = 0.0001), and between affected persons in the CBR and Control group (p < 0.05). The internal consistency of the instruments measured with Cronbach's α ranged from 0.83 to 0.96 and was very good for all instruments. Test-retest reproducibility coefficients were 0.80 for the Participation score, 0.70 for the EMIC score, 0.62 for the ISMI score and 0.50 for the GSE score. The construct validity of all instruments was confirmed. The Participation and EMIC Scales met all validity criteria, but test-retest reproducibility of the ISMI and GSE Scales needs further evaluation with a shorter test-retest interval and longer training and additional adaptations for the latter.

    Full Text Available BACKGROUND: Contacts of leprosy patients are at increased risk of developing leprosy and need to be targeted for early diagnosis. Seropositivity to the phenolic glycolipid I (PGL-I antigen of Mycobacterium leprae has been used to identify contacts who have an increased risk of developing leprosy. In the present study, we studied the effect of seropositivity in patient contacts, on the risk of developing leprosy, stratified by Bacille Calmette Guerin (BCG vaccination after index case diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: Leprosy contacts were examined as part of the surveillance programme of the Oswaldo Cruz Institute Leprosy Outpatient Clinic in Rio de Janeiro. Demographic, social, epidemiological and clinical data were collected. The presence of IgM antibodies to PGL-I in sera and BCG vaccination status at the time of index case diagnosis were evaluated in 2,135 contacts. During follow-up, 60 (2.8%; 60/2,135 leprosy cases were diagnosed: 41 among the 1,793 PGL-I-negative contacts and 19 among the 342 PGL-I-positive contacts. Among PGL-I-positive contacts, BCG vaccination after index case diagnosis increased the adjusted rate of developing clinical manifestations of leprosy (Adjusted Rate Ratio (aRR = 4.1; 95% CI: 1.8-8.2 compared with the PGL-I-positive unvaccinated contacts (aRR = 3.2; 95% CI: 1.2-8.1. The incidence density was highest during the first year of follow-up for the PGL-I-positive vaccinated contacts. However, all of those contacts developed PB leprosy, whereas most MB cases (4/6 occurred in PGL-I-positive unvaccinated contacts. CONCLUSION: Contact examination combined with PGL-I testing and BCG vaccination remain important strategies for leprosy control. The finding that rates of leprosy cases were highest among seropositive contacts justifies targeting this specific group for close monitoring. Furthermore, it is recommended that PGL-I-positive contacts and contacts with a high familial bacteriological index

    Full Text Available In Nepal, many people live with leprosy-related disabilities. The objective of this study was to evaluate differences in socio-economic characteristics, quality of life (QOL, perceived stigma, activity and participation among people affected by leprosy as a group and between this group and the general population, and to identify prime determinants of QOL among the leprosy-affected people. People with leprosy-related disabilities (N=100; 54DGI/46DGII and community controls (N=100 were selected from Morang district, South-East Nepal, using quota sampling. QOL, perceived stigma and participation and activity limitations were measured using the Nepali abbreviated version of the World Health Organisation Quality of Life (WHOQOL assessment and the Nepali versions of the Jacoby Scale, Participation Scale and Green Pastures Activity Scale (GPAS, respectively. Total QOL, participation and activity levels of people affected by leprosy were worse than those of the general population. Regression analysis showed that the ability to maintain a family, satisfaction with health, vocational training, sex, activity and participation limitations (the latter for QOL only, perceived stigma and living situation (i.e. joint family, type of house were significantly associated with a deterioration in QOL and higher participation restriction in one or both of the grading groups. There is an urgent need for interventions focused on quick referral of people with leprosy, to minimize the development of visible impairments, and social rehabilitation. The latter can be achieved by creating more public awareness, providing (financial support for income generating projects and /or vocational training to leprosy- affected people, and by encouraging them to be involved in all community development activities. The current results indicate that such measures would help improve the quality of life of people with leprosy-related disabilities.DOI 10.5463/DCID.v22i1.15

    Full Text Available Citrus leprosis is considered the main viral disease for the Brazilian citrus production, particularly for the State of São Paulo, due to the high costs spent for the chemical control of its vector, the tenuipalpid mite Brevipalpus phoenicis. In addition, its global importance has significantly increased in the last years, with the dissemination of the virus to new countries in South and Central America. In Brazil, despite its economical importance and occurrence for more than seven decades, the most significant advances towards understanding the pathosystem interactions have been obtained only in the last ten years. This review focuses on various aspects of the disease, beginning with a historical view, its main characteristics, alternatives for its control, its increasing economical importance in Brazil and abroad, and the new data on the search for understanding the interactions amongst the mite vector, the virus, and the plant host.A leprose dos citros é considerada a principal virose na citricultura brasileira, com maior destaque no Estado de São Paulo, principalmente pelos altos custos demandados para o controle químico do vetor, o ácaro Brevipalpus phoenicis. Além da relevância dessa virose para a citricultura local, sua importância mundial vem sendo ampliada consideravelmente nos últimos anos, principalmente com a disseminação do vírus em novos países da América do Sul e Central. No Brasil, apesar da sua importância econômica e ocorrência por mais de sete décadas, os mais importantes avanços no entendimento das interações do patossistema leprose têm sido obtidos apenas nos últimos dez anos. Essa revisão aborda os diferentes aspectos dessa doença, trazendo um breve histórico da doença, principais características da leprose, alternativas de controle, sua crescente importância econômica na cadeia citrícola nacional, os mais recentes relatos de sua ocorrência em outros países e os novos resultados obtidos

    Axillary nerve injury is common after brachial plexus injuries, particularly with shoulder luxation. Nerve grafting is the traditional procedure for postganglionic injuries. Nerve transfer is emerging as a viable option particularly in late referrals. At the proximal arm the radial and axillary nerves lie close by. Sacrificing one of the triceps muscle nerve branches induces little negative consequences. Transferring the long head of the triceps nerve branch is a good option to recover axillary nerve function. The surgical technique is presented in a video, stressing the steps to achieve a successful result. The video can be found here: https://youtu.be/WbVbpMuPxIE .

  12. SOCIAL PARTICIPATION OF DIABETES AND EX-LEPROSY PATIENTS IN THE NETHERLANDS AND PATIENT PREFERENCE FOR COMBINED SELF-CARE GROUPS

    Directory of Open Access Journals (Sweden)

    Henry John Christiaan De Vries

    2014-08-01

    Full Text Available Introduction: Earlier we showed that neuropathic complications limit social participation of ex-leprosy patients, even in a non-endemic leprosy setting like the Netherlands. Self-care groups for ex-leprosy patients can strengthen self-worth of participants, prevent further handicap, and enable the exchange of coping strategies. For non-endemic leprosy settings with a very low rate of leprosy patients a self-care group exclusively for (exleprosy patients is not likely to be feasible. A combined group with patients facing comparable morbidity would be more efficient than disease specific self-care groups. Here, we studied the comparability in social constraints of diabetic patients and ex-leprosy patients. Moreover, we investigated if combined self-care groups for ex-leprosy patients and diabetic patients would be desirable and acceptable for possible participants.Methods: Social participation was studied based on in-depth interviews and Participation Scale information collected from 41 diabetic patients and compared with the data of 31 ex-leprosy patients from a prior study. Moreover, we made an inventory of potential strengths and limitations and attitudes towards combined self-care groups for diabetic patients with neuropathy.Results: The following themes emerged among diabetic patients: disease confrontation, dependency, conflict with partner or relatives, feelings of inferiority, stigma, abandoning social activities, fear of the future, lack of information and hiding the disease. These themes were very similar to those voiced by the previously interviewed ex-leprosy patients. The latter more often mentioned stigma and disease ignorance among Dutch health care workers. Whereas ex-leprosy patients perceived stigma on multiple fronts, diabetic patients only mentioned feeling inferior. Diabetic patients experienced some form of participation restriction in 39% of the cases as opposed to 71% of the ex-leprosy patients. Diabetic patients did

    In 2012 the WHO Expert Committee on Leprosy published its 8th report, 14 years after the publication of its 7th report in 1998. This report, the first since the leprosy reduction goal was met in 2000, highlights key points such as improvements in the quality of various services available to patients and the efforts of individuals and societies, in addition to medical progress in diagnosis and treatment. This review will mainly describe the changes made since the 7th report. Some of the main modifications are the deletion of single lesion paucibacillary type, elongated treatment of patients with high bacterial indices, the introduction of promising new drugs, and a shift from reducing the statistical number of patients to a new target for disability prevention.

    The article investigates how knowledge of medicinal plants and related treatment practices are assimilated and transformed. Taking as its focus the use of chaulmoogra oil to treat leprosy, it examines how information on this plant was incorporated and transformed into scientifically validated knowledge when 'Brazilian chaulmoogra' came onto the scene. Pointing to the addition of chaulmoogra byproducts to the Instituto Oswaldo Cruz's production agenda in the 1920s, the study establishes links between productive processes and relates these to the period's scientific context. From the late nineteenth century until the 1940s, chaulmoogra oil was the great hope in efforts to cure leprosy. During this period, chaulmoogric treatment earned a place as scientific knowledge thanks to research studies conducted in laboratories throughout the Western world.

  15. Regeneration of Optic Nerve

    Directory of Open Access Journals (Sweden)

    Kwok-Fai So

    2011-05-01

    Full Text Available The optic nerve is part of the central nervous system (CNS and has a structure similar to other CNS tracts. The axons that form the optic nerve originate in the ganglion cell layer of the retina and extend through the optic tract. As a tissue, the optic nerve has the same organization as the white matter of the brain in regard to its glia. There are three types of glial cells: Oligodendrocytes, astrocytes, and microglia. Little structural and functional regeneration of the CNS takes place spontaneously following injury in adult mammals. In contrast, the ability of the mammalian peripheral nervous system (PNS to regenerate axons after injury is well documented. A number of factors are involved in the lack of CNS regeneration, including: (i the response of neuronal cell bodies against the damage; (ii myelin-mediated inhibition by oligodendrocytes; (iii glial scarring, by astrocytes; (iv macrophage infiltration; and (v insufficient trophic factor support. The fundamental difference in the regenerative capacity between CNS and PNS neuronal cell bodies has been the subject of intensive research. In the CNS the target normally conveys a retrograde trophic signal to the cell body. CNS neurons die because of trophic deprivation. Damage to the optic nerve disconnects the neuronal cell body from its target-derived trophic peptides, leading to the death of retinal ganglion cells. Furthermore, the axontomized neurons become less responsive to the peptide trophic signals they do receive. On the other hand, adult PNS neurons are intrinsically responsive to neurotrophic factors and do not lose trophic responsiveness after axotomy. In this talk different strategies to promote optic-nerve regeneration in adult mammals are reviewed. Much work is still needed to resolve many issues. This is a very important area of neuroregeneration and neuroprotection, as currently there is no cure after traumatic optic nerve injury or retinal disease such as glaucoma, which

    Leprosy was highly prevalent among African slaves in the Dutch West Indian colony of Suriname. Largely based on observations in Suriname, Dutch physicians described the aetiology of leprosy in terms of'a substrate' to which all sorts of mixtures of infection, heredity and hygiene contributed ('seed and soil'). This explanatory model with multiple options for prevention and treatment left room for different developmental trajectories to control the spread of the disease in the various tropical colonies of the Dutch empire. In Suriname there was a growing worry in the 19th century regarding the spread of leprosy, threatening the health of slaves, settlers and colonial administrators. And this could be harmful to an already weakening plantation economy. This concern prompted the local administration to develop a rigorous policy of strict isolation of leprosy sufferers. This, in turn, intersected with a changing insight in Europe - including the Netherlands - that leprosy was non-contagious. However,'in splendid isolation' in the economically and politically marginal colony Suriname, Dutch physicians like Charles Landre and his son, Charles Louis Drognat Landré, could afford to ignore the European non-contagious approach and continue to support the strict isolation policies. Moreover, they developed a dissident radical explanation of leprosy as a disease caused only by contagion. In the absence of a receptive Dutch audience Drognat Landré published his contagion theory in French and so succeeded in inspiring the Norwegian Hansen, who subsequently discovered the culpable micro-organism. At the same time colonial administrators and physicians in the economically and politically important Dutch colonies in the East Indies adhered to the prevailing European concept and changed policies: the system of isolation was abolished. Given the rather different trajectories of leprosy health policies in the Dutch East and West Indies we point out the importance of a comparative

    Full Text Available Leprosy, whose etiological agent is Mycobacterium leprae, is a chronic infectious disease that mainly affects the skin and peripheral nervous system. The diagnosis of leprosy is based on clinical evaluation, whereas histopathological analysis and bacilloscopy are complementary diagnostic tools. Quantitative PCR (qPCR, a current useful tool for diagnosis of infectious diseases, has been used to detect several pathogens including Mycobacterium leprae. The validation of this technique in a robust set of samples comprising the different clinical forms of leprosy is still necessary. Thus, in this study samples from 126 skin biopsies (collected from patients on all clinical forms and reactional states of leprosy and 25 slit skin smear of leprosy patients were comparatively analyzed by qPCR (performed with primers for the RLEP region of M. leprae DNA and routine bacilloscopy performed in histological sections or in slit skin smear. Considering clinical diagnostic as the gold standard, 84.9% of the leprosy patients were qPCR positive in skin biopsies, resulting in 84.92% sensitivity, with 84.92 and 61.22% positive (PPV and negative (NPV predictive values, respectively. Concerning bacilloscopy of histological sections (BI/H, the sensitivity was 80.15% and the PPV and NPV were 80.15 and 44.44%, respectively. The concordance between qPCR and BI/H was 87.30%. Regarding the slit skin smear, 84% of the samples tested positive in the qPCR. Additionally, qPCR showed 100% specificity, since all samples from different mycobacteria, from healthy individuals, and from other granulomatous diseases presented negative results. In conclusion, the qPCR technique for detection of M. leprae using RLEP primers proved to be specific and sensitive, and qPCR can be used as a complementary test to diagnose leprosy irrespective of the clinical form of disease.

    An E.M. study was carried out to investigate whether Mycobacterium leprae occur intracellularly in epidermal melanocytes. As this could not be confirmed, the selective killing of melanocytes by cytotoxic lymphocytes could not explain the hypopigmentation in types of leprosy with a relative good immune response. There were indications that these hypopigmented lesions resulted from a disturbed transfer of melanosomes from melanocytes to keratinocytes. Further research is in progress.

    To analyze the epidemiology of leprosy according to spatial distribution and living conditions of the population. Ecological study based on the spatial distribution of leprosy in the municipality of Manaus, Northern Brazil, from 1998 to 2004. The 4,104 cases identified in the Sistema de Informações de Agravos de Notificação (Sinan -National Notification System) were georeferenced according to the addresses in the 1,536 urban census tracts through four different sources: postal service (73.7% of addresses found), Property Registration Program (7.3%), Family Health Program (2.1%), and Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics) data sheet (1.5%). Calculation of detection coefficient was performed based on the 2001 population. Local empirical Bayesian method was used for the spatial distribution analysis, in order to estimate leprosy risk, making rate variation shorter when they were calculated for small areas. Logistic regression was employed to analyze the association between geographical distribution and risk factors. The incidence of cases in children under 15 (severity indicator) and Social Need Index built from variables of the 2000 census were adopted as explicative variables. The mean coefficient of detection was hyperendemic in 34.0% of the census tracts, and very high in 26.7%. Odds ratio was obtained for explicative variables and proved to be significant. Low-income and incidence in children under 15 were combined to identify priority areas for intervention. Spatial analysis of leprosy showed that the distribution of the disease is heterogeneous and is more strongly present in regions inhabited by more vulnerable groups.

    Leprosy-related disability is a challenge to public health, and social and rehabilitation services in endemic countries. Disability is more than a mere physical dysfunction, and includes activity limitations, stigma, discrimination, and social participation restrictions. We assessed the extent of disability and its determinants among persons with leprosy-related disabilities after release from multi drug treatment. We conducted a survey on disability among persons affected by leprosy in Indonesia, using a Rapid Disability Appraisal toolkit based on the International Classification of Functioning, Disability and Health. The toolkit included the Screening of Activity Limitation and Safety Awareness (SALSA) scale, Participation Scale, Jacoby Stigma Scale (anticipated stigma), Explanatory Model Interview Catalogue (EMIC) stigma scale and Discrimination assessment. Community members were interviewed using a community version of the stigma scale. Multivariate linear regression was done to identify factors associated with social participation. Overall 1,358 persons with leprosy-related disability (PLD) and 931 community members were included. Seventy-seven percent of PLD had physical impairments. Impairment status deteriorated significantly after release from treatment (from 59% to 77%). Around 60% of people reported activity limitations and participation restrictions and 36% anticipated stigma. As for participation restrictions and stigma, shame, problems related to marriage and difficulties in employment were the most frequently reported problems. Major determinants of participation were severity of impairment and level of education, activity and stigma. Reported severity of community stigma correlated with severity of participation restrictions in the same districts. The majority of respondents reported problems in all components of disability. The reported physical impairment after release from treatment justifies ongoing monitoring to facilitate early prevention

    The present study aims at evaluating the decentralisation of the leprosy control activities in the municipality of Betim, Minas Gerais, Brazil. A quantitative study was undertaken using data from SINAN (Sistema Nacional de Agravos de Notificação) and patient records. The study included 435 new cases registered and living in Betim. The pre (1995-2000) and post (2001-2005) decentralisation periods were compared using the chi-square test. Besides this, units which already had leprosy control activities were compared to those which implemented them from 2001 on. There was a decrease in the percentage of cases diagnosed with deformities after decentralisation, as well as an increase in the number of cases detected through self-reporting. More patients were notified closer to home after decentralisation. The selected indicators did not show any difference between the quality of assistance regarding prevention of disabilities when comparing health units which already had leprosy activities to those which implemented them from 2001 onwards. Decentralisation, in Betim, did not lead to an increase in the number of cases, but led to earlier diagnosis and patients being treated closer to their homes. The study did not show evidence of decrease in the quality of care after decentralisation.

    The Millennium Development Goals have provided much needed attention to extreme poverty reduction. However, people with disabilities are disproportionately affected by poverty and in some countries, even the goal of US$1 per day is far out of reach. For people with leprosy-related disability living in ultra-poverty (on less than 50 cents a day), many mainstream poverty reduction strategies are inaccessible and inappropriate. A project in north-west Bangladesh developed a more contextually meaningful definition of ultra-poverty according to nutrition energy intake. A total of 2372 people with leprosy-related disability were surveyed. Of those, 1285 individuals fell below the ultra-poverty line. Individualised interventions were implemented over an extended period of time, comprised of targeted practical assistance, enhancing community links, advocacy for entitlements, and further linking with other initiatives. Follow-up data available for 856 individuals showed an average increase in per capita income of 83%. Personal contribution to the family income increased by 65%. There was a 51% increase in families having access to a latrine. Finally families reported eating 30% more meals per day, up from an average of two meals per day. The initiative sought to address poverty in a wide variety of ways, using minimal inputs. Over several years, the results indicate a significant change in the economic situation of individuals with leprosy related disabilities. Other organisations are encouraged to duplicate the intervention and share their results.

    Leprosy is an infectious, chronic granulomatous disease, caused by M. leprae. It is one of the most seriously disabling and economically important disease. In Sudan it affects about 20 thousands people. In this study 60 patients of MB leprosy were included. Historry and physical examination were carried out for each patient. BI was done for all patients and were subjected to x-ray investigations of the paranasal sinuses, hands and feet. 85%(51) of these patients were found to have radiographic changes in paranasal sinuses, 35 patients with mucosal thickening and 16 with diffuse opacified sinuses. 86.7% (52) of those patients were found to have radiographic bone changes in their hand and feet. 23.6% and 75.4% were found with specific and non-specific bone changes in their hands and feet respectively. A spectrum of radiographic bone changes was found in the hands and feet including; destruction, fractures, phalangeal resoption, distal phalangeal tapering, flexion deformities, osteoarthritic changes, charcot's joints, osteoporosis cystic bone changes and enlarged nutrient bone foramina. The majority of patients with radiographic changes in the paranasal sinsuses, hands and feet, were found to have long duration of the disease and more bacterial load. The disability in hands and feet is the major risk factor in bone affection in MB leprosy. (Author)

    Full Text Available Abstract Introduction In previous studies, women are less aware of causation and symptoms of leprosy and have less access to health care coverage than men, thus contributing to their delay in seeking for treatment. We assess the gender differences in leprosy cases admitted to a rural referral hospital in Ethiopia for 7 and a half years. Methods Retrospective data of the leprosy patients admitted to referral hospital were collected using leprosy admission registry books from September 2002 to January 2010. Variables were entered in an Excel 97 database. Results During the period of study, 839 patients with leprosy were admitted; 541 (64.5% were male, and 298 (35.6% female. Fifteen per cent of female patients, and 7.3% of male patients were paucibacillary leprosy cases while 84.8% of female patients and 92.7% of males were multibacillary leprosy cases (p Conclusions Female patients with leprosy admitted to hospital were younger, had a different profile of admission and a higher mortality rate than male ones.

    To compare the functional and EMG outcomes of long-nerve grafts to nerve transfers for complete axillary nerve palsy. Over a 10-year period at a single institution, 14 patients with axillary nerve palsy were treated with long-nerve grafts and 24 patients were treated with triceps-to-axillary nerve transfers by the same surgeon (S.W.W.). Data were collected prospectively at regular intervals, beginning before surgery and continuing up to 11 years after surgery. Prior to intervention, all patients demonstrated EMG evidence of complete denervation of the deltoid. Deltoid recovery (Medical Research Council [MRC] grade), shoulder abduction (°), improvement in shoulder abduction (°), and EMG evidence of deltoid reinnervation were compared between cohorts. There were no significant differences between the long-nerve graft cohort and the nerve transfer cohort with respect to postoperative range of motion, deltoid recovery, improvement in shoulder abduction, or EMG evidence of deltoid reinnervation. These data demonstrate that outcomes of long-nerve grafts for axillary nerve palsy are comparable with those of modern nerve transfers and question a widely held belief that long-nerve grafts do poorly. When healthy donor roots or trunks are available, long-nerve grafts should not be overlooked as an effective intervention for the treatment of axillary nerve injuries in adults with brachial plexus injuries.

    This paper evaluates the utility of multiplanar reconstructions (MPRs) of three-dimensional (3D) MR angiography data sets in the examination of patients with cranial nerve palsies. The authors hypothesis was that 3D data could be reformatted to highlight the intricate spatial relationships of vessels to adjacent neural tissues by taking advantage of the high vessel-parenchyma contrast in high-resolution 3D time-of-flight sequences. Twenty patients with cranial nerve palsies and 10 asymptomatic patients were examined with coronal T1-weighted and axial T2-weighted imaging plus a gadolinium-enhanced 3D MRA sequence (40/7/15 degrees, axial 60-mm volume, 0.9-mm isotropic resolution). Cranial nerves II-VIII were subsequently evaluated on axial and reformatted coronal and/or sagittal images

    Vitamin D Receptor (VDR) is a transacting transcription factor which mediates immunomodulatory function and plays a key role in innate and adaptive immune responses through its ligand and polymorphisms in VDR gene may affect its regulatory function. To investigate the association of three VDR gene polymorphisms (TaqI rs731236, FokI rs2228570 and ApaI rs7975232) with leprosy. The study group includes 404 participants of which 222 were leprosy patients (paucibacillary=87, multibacillary=135) and 182 healthy controls. Genotyping was done using PCR-RFLP technique. Statistical analysis was performed using SNP Stats and PLINK software. The VDR FokI (rs2228570) ff genotype, ApaI (rs7975232) AA, Aa genotype and haplotype T-f-a, T-F-A were positively associated with leprosy when compared to healthy controls. The two variants at Fok and Apa positions in VDR gene are significantly associated with leprosy. Genotypes at FokI (ff), ApaI (aa) and haplotype (T-F-a, T-f-a) may contribute to the risk of developing leprosy by altering VDR phenotype/levels subsequently modulation of immune response.

    Hand and upper extremity function is instrumental to basic activities of daily living and level of independence in cervical spinal cord injury (SCI). Nerve transfer surgery is a novel and alternate approach for restoring function in SCI. This article discusses the biologic basis of nerve transfers in SCI, patient evaluation, management, and surgical approaches. Although the application of this technique is not new; recent case reports and case series in the literature have increased interest in this field. The challenges are to improve function, achieve maximal gains in function, avoid complications, and to primum non nocere. Copyright © 2016 Elsevier Inc. All rights reserved.

    A variety of lesions may involve the optic nerve. Mainly, these lesions are inflammatory or vascular lesions that rarely necessitate surgery but may induce significant visual morbidity. Orbital tumors may induce proptosis, visual loss, relative afferent pupillary defect, disc edema and optic...... atrophy, but less than one-tenth of these tumors are confined to the optic nerve or its sheaths. No signs or symptoms are pathognomonic for tumors of the optic nerve. The tumors of the optic nerve may originate from the optic nerve itself (primary tumors) as a proliferation of cells normally present...... in the nerve (e.g., astrocytes and meningothelial cells).

    The purpose of this study was to compare functional outcomes between nerve grafting and nerve transfer procedures in the setting of isolated, posttraumatic axillary nerve injuries. A systematic review was performed using the PubMed, Scopus, and Cochrane databases to identify all cases of isolated, posttraumatic axillary nerve injuries in patients aged 18 years or older. Patients who underwent axillary nerve reconstruction were included and categorized by technique: graft or transfer. Demographics were recorded, including age, time to operation, and presence of concomitant injuries. Functional outcomes were evaluated, including British Medical Research Council strength and range of motion for shoulder abduction. Ten retrospective studies met criteria, for a total of 66 patients (20 nerve grafts and 46 nerve transfers). Median time from injury to operation was equivalent across the nerve graft and nerve transfer groups (8.0 months versus 7.0 months; p = 0.41). Postoperative follow-up was 24.0 months for nerve grafting versus 18.5 months for nerve transfer (p = 0.13). Clinically useful shoulder abduction, defined as British Medical Research Council grade M3 or greater, was obtained in 100 percent of nerve graft patients versus 87 percent of nerve transfer patients (p = 0.09). Grade M4 or better strength was obtained in 85 percent of nerve graft patients and 73.9 percent of nerve transfer patients (p = 0.32). Significant differences in functional outcomes between nerve graft and transfer procedures for posttraumatic axillary nerve injuries are not apparent at this time. Prospective outcomes studies are needed to better elucidate whether functional differences do exist. Therapeutic, IV.

    The causal agents of Citrus leprosis are viruses; however, extant diagnostic methods to identify them have failed to detect known viruses in orange, mandarin, lime and bitter orange trees with severe leprosis symptoms in Mexico, an important citrus producer. Using high throughput sequencing, a virus associated with citrus leprosis was identified, belonging to the proposed Dichorhavirus genus. The virus was termed Citrus Necrotic Spot Virus (CNSV) and contains two negative-strand RNA components; virions accumulate in the cytoplasm and are associated with plasmodesmata—channels interconnecting neighboring cells—suggesting a mode of spread within the plant. The present study provides insights into the nature of this pathogen and the corresponding plant response, which is likely similar to other pathogens that do not spread systemically in plants.

    Full Text Available We studied the roles of vitamin D and its receptor, VDR, in the progression of leprosy. The majority of individuals with leprosy from Kolkata, India, with a type 1 or type 2 reaction have low levels of vitamin D3 in serum samples. Interestingly, individuals with a type 2 reaction associated with neuritis/erythema nodosum leprosum had very low VDR mRNA expression levels, ranging from 5% to 10%, compared to that of healthy control subjects; these patients also had a high bacilli index, ranging from 3+ to 5+. This is the first report to indicate that VDR expression levels may determine the complexity and severity of the progression of leprosy.

    2014-12-01

    To investigate spatial clusters and possible associations between relative risks of leprosy with socio-economic and environmental factors, taking into account diagnosed cases in children under 15 years old. An ecological study was conceived using data aggregated by municipality to identify possible spatial clusters of leprosy from 2005 to 2011. Relative risks were calculated accounting for the respective covariate gender. The second stage of the analysis consisted of verifying possible associations between the relative risks of leprosy as a dependent variable, and socio-economic and environmental variables as independent. This was performed using a multivariate regression analysis according to a previously defined conceptual framework. Overall rates have decreased from 0.88/10 000 in 2005 to 0.52 in 2011. Spatial scan statistics identified 4 high-risk and 6 low-risk clusters. In the regression model, after allowing for spatial dependence, relative risks were associated with higher percentage of water bodies, higher Gini index, higher percentage of urban population, larger average number of dwellers by permanent residence and smaller percentage of residents born in Bahia. Although relative risks of leprosy in Bahia have been decreasing, they remain very high. The association between relative risks of leprosy and water bodies in the proposed geographic scale indicates that hypothesis linking M. leprae and humid environments cannot be discarded. Socio-economic conditions such as inequality, a greater number of dwellers by residence and migration are derived from the urbanisation process carried out in this State. Precarious settlements and poor living conditions in the cities would favour the continuity of leprosy transmission. © 2014 John Wiley & Sons Ltd.

  6. Human Genetic Ancestral Composition Correlates with the Origin of Mycobacterium leprae Strains in a Leprosy Endemic Population.

    Directory of Open Access Journals (Sweden)

    Nora Cardona-Castro

    Full Text Available Recent reports have suggested that leprosy originated in Africa, extended to Asia and Europe, and arrived in the Americas during European colonization and the African slave trade. Due to colonization, the contemporary Colombian population is an admixture of Native-American, European and African ancestries. Because microorganisms are known to accompany humans during migrations, patterns of human migration can be traced by examining genomic changes in associated microbes. The current study analyzed 118 leprosy cases and 116 unrelated controls from two Colombian regions endemic for leprosy (Atlantic and Andean in order to determine possible associations of leprosy with patient ancestral background (determined using 36 ancestry informative markers, Mycobacterium leprae genotype and/or patient geographical origin. We found significant differences between ancestral genetic composition. European components were predominant in Andean populations. In contrast, African components were higher in the Atlantic region. M. leprae genotypes were then analyzed for cluster associations and compared with the ancestral composition of leprosy patients. Two M. leprae principal clusters were found: haplotypes C54 and T45. Haplotype C54 associated with African origin and was more frequent in patients from the Atlantic region with a high African component. In contrast, haplotype T45 associated with European origin and was more frequent in Andean patients with a higher European component. These results suggest that the human and M. leprae genomes have co-existed since the African and European origins of the disease, with leprosy ultimately arriving in Colombia during colonization. Distinct M. leprae strains followed European and African settlement in the country and can be detected in contemporary Colombian populations.

    Carla Andréa Avelar Pires

    Full Text Available Leprosy, caused by Mycobacterium leprae, can lead to scarring and deformities. Human immunodeficiency virus (HIV, a lymphotropic virus with high rates of replication, leads to cell death in various stages of infection. These diseases have major social and quality of life costs, and although the relevance of their comorbidity is recognized, several aspects are still not fully understood.Two cohorts of patients with leprosy in an endemic region of the Amazon were observed. We compared 40 patients with leprosy and HIV (Group 1 and 107 leprosy patients with no comorbidity (Group 2 for a minimum of 2 years. Group 1 predominantly experienced the paucibacillary classification, accounting for 70% of cases, whereas Group 2 primarily experienced the multibacillary classification (80.4% of cases. There was no significant difference in the prevalence of leprosy reactions among the two groups (37.5% for Group 1 vs. 56.1% for Group 2, and the most frequent reaction was Type 1. The appearance of Group 1 patients' reversal reaction skin lesions was consistent with each clinical form: typically erythematous and infiltrated, with similar progression as those patients without HIV, which responded to prednisone. Patients in both groups primarily experienced a single episode (73.3% in Group 1 and 75% in Group 2, and Group 1 had shorter reaction periods (≤3 months; 93.3%, moderate severity (80%, with 93.3% of the patients in the state of acquired immune deficiency syndrome, and 46.7% presenting the reaction at the time of the immune reconstitution inflammatory syndrome.This study used a large sample and makes a significant contribution to the clinical outcomes of patients in the reactive state with comorbid HIV and leprosy. The data indicate that these diseases, although concurrent, have independent courses.

  8. The challenge of producing skin test antigens with minimal resources suitable for human application against a neglected tropical disease; leprosy.

    Directory of Open Access Journals (Sweden)

    Becky L Rivoire

    Full Text Available True incidence of leprosy and its impact on transmission will not be understood until a tool is available to measure pre-symptomatic infection. Diagnosis of leprosy disease is currently based on clinical symptoms, which on average take 3-10 years to manifest. The fact that incidence, as defined by new case detection, equates with prevalence, i.e., registered cases, suggests that the cycle of transmission has not been fully intercepted by implementation of multiple drug therapy. This is supported by a high incidence of childhood leprosy. Epidemiological screening for pre-symptomatic leprosy in large endemic populations is required to facilitate targeted chemoprophylactic interventions. Such a test must be sensitive, specific, simple to administer, cost-effective, and easy to interpret. The intradermal skin test method that measures cell-mediated immunity was explored as the best option. Prior knowledge on skin testing of healthy subjects and leprosy patients with whole or partially fractionated Mycobacterium leprae bacilli, such as Lepromin or the Rees' or Convit' antigens, has established an acceptable safety and potency profile of these antigens. These data, along with immunoreactivity data, laid the foundation for two new leprosy skin test antigens, MLSA-LAM (M. leprae soluble antigen devoid of mycobacterial lipoglycans, primarily lipoarabinomannan and MLCwA (M. leprae cell wall antigens. In the absence of commercial interest, the challenge was to develop these antigens under current good manufacturing practices in an acceptable local pilot facility and submit an Investigational New Drug to the Food and Drug Administration to allow a first-in-human phase I clinical trial.

    Full Text Available Abstract Background Leprosy is a chronic infectious disease that has an impact on the Health-Related Quality of Life (HRQOL of sufferers as well as their children. To date, no study has investigated the effects of parental leprosy on the well-being of adolescent children. Methods A cross-sectional study was conducted in the Lalitpur and Kathmandu districts of Nepal. Adolescents with leprosy-affected parents (n = 102; aged 11–17 years and those with parents unaffected by leprosy (n = 115; 11–17 years were investigated. Self-reported data from adolescents were collected using the Kinder Lebensqualität Fragebogen (KINDLR questionnaire to assess HRQOL, the Center for Epidemiological Studies-Depression Scale (CES-D, and the Rosenberg Self-esteem Scale (RSES. Analysis of covariance (ANCOVA was used to compare scores between the two groups. Multiple regression analysis was conducted to explore the determinants of HRQOL for adolescents with leprosy-affected parents. Results ANCOVA revealed that the KINDLR and RSES scores were significantly lower among adolescents with leprosy-affected parents compared with unaffected parents. However, the scores of “Friends” and “School” subscales of KINDLR were similar between the two groups. The CES-D score was significantly higher among adolescents with leprosy-affected parents than for adolescents with unaffected parents. The KINDLR scores for adolescents with both parents affected (n = 41 were significantly lower than the scores for those with one parent affected (n = 61. Multiple regression analysis revealed that adolescents with leprosy-affected parents who had higher levels of depressive symptoms were more likely to have lower KINDLR scores. A similar result was seen for adolescents where both parents had leprosy. Conclusions Adolescents with leprosy-affected parents had higher levels of depressive symptoms, lower levels of self-esteem, and lower HRQOL compared with adolescents whose

Adolescents with leprosy-affected parents (n = 102; aged 11-17 years) and those with parents unaffected by leprosy (n = 115; 11-17 years) were investigated. Self-reported data from adolescents were collected using the Kinder Lebensqualität Fragebogen (KINDLR) questionnaire to assess HRQOL, the Center for Epidemiological Studies-Depression Scale (CES-D), and the Rosenberg Self-esteem Scale (RSES). Analysis of covariance (ANCOVA) was used to compare scores between the two groups. Multiple regression analysis was conducted to explore the determinants of HRQOL for adolescents with leprosy-affected parents. ANCOVA revealed that the KINDLR and RSES scores were significantly lower among adolescents with leprosy-affected parents compared with unaffected parents. However, the scores of "Friends" and "School" subscales of KINDLR were similar between the two groups. The CES-D score was significantly higher among adolescents with leprosy-affected parents than for adolescents with unaffected parents. The KINDLR scores for adolescents with both parents affected (n = 41) were significantly lower than the scores for those with one parent affected (n = 61). Multiple regression analysis revealed that adolescents with leprosy-affected parents who had higher levels of depressive symptoms were more likely to have lower KINDLR scores. A similar result was seen for adolescents where both parents had leprosy. Adolescents with leprosy-affected parents had higher levels of depressive symptoms, lower levels of self-esteem, and lower HRQOL compared with adolescents whose parents were unaffected by leprosy. Thus, mental health support

    There is a large scala of pathology affecting the vestibulocochlear nerve. Magnetic resonance imaging is the method of choice for the investigation of pathology of the vestibulocochlear nerve. Congenital pathology mainly consists of agenesis or hypoplasia of the vestibulocochlear nerve. Tumoral pathology affecting the vestibulocochlear nerve is most frequently located in the internal auditory canal or cerebellopontine angle. Schwannoma of the vestibulocochlear nerve is the most frequently found tumoral lesion followed by meningeoma, arachnoid cyst and epidermoid cyst. The most frequently encountered pathologies as well as some more rare entities are discussed in this chapter.

    Vascularized nerve grafts (VNG) were introduced in 1976 but since then, there have been no reports of their usage in lower extremity reconstruction systematically. The factors influencing outcomes as well as a comparison with conventional nerve grafts will be presented.Since 1981, 14 lower extremity nerve injuries in 12 patients have been reconstructed with VNG. Common peroneal nerve was injured in 12 and posterior tibial nerve in 5 patients. The level of the injury was at the knee or thigh. Twelve sural nerves were used as VNG with or without concomitant vascularized posterior calf fascia.All patients regained improved sensibility and adequate posterior tibial nerve function. For common peroneal nerve reconstructions, all patients with denervation time less than 6 months regained muscle strength of grade at least 4, even when long grafts were used for defects of 20 cm or more. Late cases, yielded inadequate muscle function even with the use of VNG.Denervation time of 6 months or less was critical for reconstruction with vascularized nerve graft. Not only the results were statistically significant compared with late cases, but also all early operated patients achieved excellent results. VNG are strongly recommended in traction avulsion injuries of the lower extremity with lengthy nerve damage.

    Leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae), which has massive genomic decay and dependence on host metabolism. Accumulating evidence showed a crucial role of mitochondria in metabolism and innate immunity. We hypothesized that the mitochondrial-related antimicrobial/antiviral immune genes MAVS (mitochondrial antiviral signaling protein), MITA (mediator of IRF3 activation) and MFN2 (mitofusin 2) would confer a risk to leprosy. In this study, we performed a case-control study to analyze 11 tag and/or non-synonymous SNPs of the MAVS, MITA and MFN2 genes in 527 leprosy patients and 583 healthy individuals, and directly sequenced the three genes in 80 leprosy patients with a family history from Yunnan, Southwest China. We found no association between these SNPs and leprosy (including its subtypes) based on the frequencies of alleles, genotypes and haplotypes between the cases and controls. There was also no enrichment of potential pathogenic variants of the three genes in leprosy patients. Our results suggested that genetic variants of the MAVS, MITA and MFN2 genes might not affect the susceptibility to leprosy. Copyright © 2016 Elsevier B.V. All rights reserved.

    The purpose of this study was to observe whether our custom made shoes and total contact insoles can effectively increase the plantar contact areas and reduce peak pressures in patients with leprosy. In the rehabilitation laboratory of a tertiary medical center. Six male and two female leprosy patients were recruited in this study. In this study, parameters related to foot pressures were compared between these patients wearing commercial available soft-lining kung-fu shoes and our custom made shoes with total contact insoles. The custom made shoes were made with larger toe box and were able to accommodate both the foot and the insoles. Custom made total contact insoles were made with the subtalar joints under neutral and non-weight-bearing positions. The insole force measurement system of Novel Pedar-X (Novel, Munich, Germany) was used to measure the plantar forces. The parameters of contact area (cm(2)), peak plantar pressures (kPa), contact time (s), and pressure time integral (kPa s) were measured. There were significant contact area increases in the right and left foot heel areas, left medial arch, and second to fifth toes after wearing the custom made shoes and insoles. There were significant decreases in peak plantar pressures in bilateral heels, left lateral midfoot, bilateral second to fourth metatarsal areas, and left fifth metatarsal head after wearing the custom made shoes and insoles (pshoes and total contact insoles were proven to be effective in increasing contact areas and decreasing peak pressures in plantar surfaces, and may therefore be a feasible treatment option in preventing leprosy patients from developing plantar ulcers. © 2015 Elsevier B.V.

    Full Text Available Since leprosy is both treated and controlled by multidrug therapy (MDT it is important to monitor recurrent cases for drug resistance and to distinguish between relapse and reinfection as a means of assessing therapeutic efficacy. All three objectives can be reached with single nucleotide resolution using next generation sequencing and bioinformatics analysis of Mycobacterium leprae DNA present in human skin.DNA was isolated by means of optimized extraction and enrichment methods from samples from three recurrent cases in leprosy patients participating in an open-label, randomized, controlled clinical trial of uniform MDT in Brazil (U-MDT/CT-BR. Genome-wide sequencing of M. leprae was performed and the resultant sequence assemblies analyzed in silico.In all three cases, no mutations responsible for resistance to rifampicin, dapsone and ofloxacin were found, thus eliminating drug resistance as a possible cause of disease recurrence. However, sequence differences were detected between the strains from the first and second disease episodes in all three patients. In one case, clear evidence was obtained for reinfection with an unrelated strain whereas in the other two cases, relapse appeared more probable.This is the first report of using M. leprae whole genome sequencing to reveal that treated and cured leprosy patients who remain in endemic areas can be reinfected by another strain. Next generation sequencing can be applied reliably to M. leprae DNA extracted from biopsies to discriminate between cases of relapse and reinfection, thereby providing a powerful tool for evaluating different outcomes of therapeutic regimens and for following disease transmission.

    The diagnosis of cerebral venous sinus thrombosis still remains a real challenge. Seizure, unusual headache with sudden onset, unexplained persistently unilateral vascular headache and neurologic deficit-which is difficult to be attributed to a vascular territory are some of the suggestive symptoms. An isolated sixth nerve palsy is discussed as a rare presentation for cerebral venous thrombosis. Following the extensive investigation to rule out other possible diagnoses, magnetic resonance venogram revealed the final etiology of sixth nerve palsy that was ipsilateral left transverse sinus thrombosis; therefore, anticoagulant treatment with low molecular weight heparin was administered. Rapid and accurate diagnosis and treatment cause to achieve excellent outcomes for most patients. Considering different clinical features, risk factors and high index of suspicion are helpful to reach the diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    At the Abony-Turjányos dűlő site, located in Central Hungary, a rescue excavation was carried out. More than 400 features were excavated and dated to the Protoboleráz horizon, at the beginning of the Late Copper Age in the Carpathian Basin, between 3780-3650 cal BC. Besides the domestic and economic units, there were two special areas, with nine-nine pits that differed from the other archaeological features of the site. In the northern pit group seven pits contained human remains belonging to 48 individuals. Some of them were buried carefully, while others were thrown into the pits. The aim of this study is to present the results of the paleopathological and molecular analysis of human remains from this Late Copper Age site. The ratio of neonates to adults was high, 33.3%. Examination of the skeletons revealed a large number of pathological cases, enabling reconstruction of the health profile of the buried individuals. Based on the appearance and frequency of healed ante- and peri mortem trauma, inter-personal (intra-group) violence was characteristic in the Abony Late Copper Age population. However other traces of paleopathology were observed on the bones that appear not to have been caused by warfare or inter-group violence. The remains of one individual demonstrated a rare set of bone lesions that indicate the possible presence of leprosy (Hansen's disease). The most characteristic lesions occurred on the bones of the face, including erosion of the nasal aperture, atrophy of the anterior nasal spine, inflammation of the nasal bone and porosity on both the maxilla and the bones of the lower legs. In a further four cases, leprosy infection is suspected but other infections cannot be excluded. The morphologically diagnosed possible leprosy case significantly modifies our knowledge about the timescale and geographic spread of this specific infectious disease. However, it is not possible to determine the potential connections between the cases of possible leprosy

    Full Text Available Abstract: INTRODUCTION: The incidence of Hansen's disease is high in overlooked populations. METHODS: Data of Hansen's disease cases reported in the information system of the Department of Informatics, Brazilian Unified Health System, from 2013 to 2014 were analyzed. RESULTS: Among 434 studied cases of Hansen's disease, the female sex (52.5%, adult age (73.7%, low educational level (61.8%, and multibacillary form were associated with higher prevalence rates. CONCLUSIONS: Hansen's disease is more frequent among female adults with a low educational level, and the prevalence of multibacillary leprosy reflects disease detection at late stages.

    Ismail, Hossam El-din Ali

    2017-01-01

    Full Text Available Introduction: The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients. The current study is to present our clinical experience and evaluate the use of sural flap with posterior tibial neurovascular decompression (PTND in recurrent foot ulcers in leprosy patients.Patient and methods: A total number of 9 patients were suffering from chronic sequelae of leprosy as recurrent foot ulcers. All the patients were reconstructed with the reverse sural artery fasciocutaneous flap with posterior tibial neurovascular decompression from September 2012 to August 2015. Six patients were male and three were female with a mean age of 39.8 years (range, 30–50 years. All the soft tissue defects were in the weight-bearing area of the inside of the foot. The flap sizes ranged from 15/4 to 18/6 cm. Mean follow-up period was 21.2 months (range, 35–2 months.Results: All the flaps healed uneventfully. There was no major complication as total flap necrosis. Only minor complications occurred which were treated without surgical intervention except in two patients who developed superficial necrosis of the skin paddle. Surgical debridement was done one week later. The flap was completely viable after surgery, and the contour of the foot was restored. We found that an improvement of sensation occurred in those patients in whom the anesthesia started one year ago or less and no sensory recovery in patient in whom the anesthesia had lasted for more than two years.Conclusion: The reverse sural artery flap with posterior tibial neurovascular decompression provides a reliable method for recurrent foot soft tissue reconstruction in leprosy patients with encouraging

    In previous studies, women are less aware of causation and symptoms of leprosy and have less access to health care coverage than men, thus contributing to their delay in seeking for treatment. We assess the gender differences in leprosy cases admitted to a rural referral hospital in Ethiopia for 7 and a half years. Retrospective data of the leprosy patients admitted to referral hospital were collected using leprosy admission registry books from September 2002 to January 2010. Variables were entered in an Excel 97 database. During the period of study, 839 patients with leprosy were admitted; 541 (64.5%) were male, and 298 (35.6%) female. Fifteen per cent of female patients, and 7.3% of male patients were paucibacillary leprosy cases while 84.8% of female patients and 92.7% of males were multibacillary leprosy cases (p<0.001). Female leprosy patients were younger than male ones (median: 36 versus 44 years) (p<0.001). In the multivariate analysis, age (odds ratio [OR]: 0.97; 95% confidence interval [CI]: 0.96-0.98; p<0.001), admission for cardiovascular diseases (OR: 7.6, 95% CI: 1.9-29.3; p=0.004), admission for gastroenteritis (OR: 14.0; 95% CI: 1.7-117; p=0.02), admission from out patients clinic (OR: 2.04; 95% CI: 1.1-4.01; p=0.02), and mortality as final outcome (OR: 3.1, 95% CI: 1.2-8.0; p=0.02) were independently associated with female gender. Female patients with leprosy admitted to hospital were younger, had a different profile of admission and a higher mortality rate than male ones.

    Full Text Available Optic nerve hypoplasia (ONH is a congenital anomaly of the optic disc that might result in moderate to severe vision loss in children. With a vast number of cases now being reported, the rarity of ONH is obviously now refuted. The major aspects of ophthalmic evaluation of an infant with possible ONH are visual assessment, fundus examination, and visual electrophysiology. Characteristically, the disc is small, there is a peripapillary double-ring sign, vascular tortuosity, and thinning of the nerve fiber layer. A patient with ONH should be assessed for presence of neurologic, radiologic, and endocrine associations. There may be maternal associations like premature births, fetal alcohol syndrome, maternal diabetes. Systemic associations in the child include endocrine abnormalities, developmental delay, cerebral palsy, and seizures. Besides the hypoplastic optic nerve and chiasm, neuroimaging shows abnormalities in ventricles or white- or gray-matter development, septo-optic dysplasia, hydrocephalus, and corpus callosum abnormalities. There is a greater incidence of clinical neurologic abnormalities in patients with bilateral ONH (65% than patients with unilateral ONH. We present a review on the available literature on the same to urge caution in our clinical practice when dealing with patients with ONH. Fundus photography, ocular coherence tomography, visual field testing, color vision evaluation, neuroimaging, endocrinology consultation with or without genetic testing are helpful in the diagnosis and management of ONH.

    The nerves and nerve endings in the skin of tropical cattle were studied using histological and histochemical techniques. Many nerve trunks and fibres were present in the reticular and papillary dermis in both hairy and non-hairy skin sites. In non-hairy skin locations such as the muzzle and lower lip, encapsulated endings akin to Krause and Ruffini end bulbs, which arise from myelinated nerve trunks situated lower down the dermis were observed at the upper papillary layer level. Some fibre trunks seen at this level extended upwards to terminate within dermal papillae as bulb-shaped longitudinally lamellated Pacinian-type endings, while other onion-shaped lamellated nerve structures were located either within dermal papillae or near the dermo-epidermal area. Intraepidermal free-ending nerve fibres, appearing non-myelinated were observed in areas with thick epidermis. Intraepidermal free-ending nerve fibres, appearing non-myelinated were observed in areas with thick epidermis. On hairy skin sites, however, organized nerve endings or intraepidermal nerve endings were not readily identifiable.

    Peripheral nerve injury can lead to great morbidity in those afflicted, ranging from sensory loss, motor loss, chronic pain, or a combination of deficits. Over time, research has investigated neuronal molecular mechanisms implicated in nerve damage, classified nerve injury, and developed surgical techniques for treatment. Despite these advancements, full functional recovery remains less than ideal. In this review, we discuss historical aspects of peripheral nerve injury and introduce nerve transfer as a therapeutic option, as well as an adjunct therapy to transplantation of Schwann cells and their stem cell derivatives for repair of the damaged nerve. This review furthermore, will provide an elaborated discussion on the sources of Schwann cells, including sites to harvest their progenitor and stem cell lines. This reflects the accessibility to an additional, concurrent treatment approach with nerve transfers that, predicated on related research, may increase the efficacy of the current approach. We then discuss the experimental and clinical investigations of both Schwann cells and nerve transfer that are underway. Lastly, we provide the necessary consideration that these two lines of therapeutic approaches should not be exclusive, but conversely, should be pursued as a combined modality given their mutual role in peripheral nerve regeneration.

    Background Few studies have evaluated the association between quality of life (QoL) and functional activity limitations (FAL) of leprosy patients as determined by the Screening of Activity Limitation and Safety Awareness scale (SALSA). Aim To identify the association between FALs and the QoL of patients during and post leprosy treatment. Materials and Methods Cross-sectional survey of 104 patients with leprosy followed in specialist reference centres in Sergipe, Brazil, between June and October 2014. QoL was evaluated using the World Health Organization-QoL-BREF (WHOQoL-BREF) questionnaire. The SALSA scale was used to measure FALs. Results Low SALSA scores were present in 76% of patients. QoL scores were lower for the physical and environmental domains, with median (interquartile range (IQR)) scores of 53.6 (32.1–67.9) and 53.1 (46.9–64.8), respectively. There was a statistical association between increasing SALSA scores and lower QoL as measured by the WHOQoL-BREF. Conclusion Functional limitations are associated with lower QoL in leprosy patients, especially in the physical and environmental WHOQoL-BREF domains. PMID:26132166

    Polymorphisms present in the first intron of IFN-γ may have an important role in the regulation of the immune response, which could have functional consequences for gene transcription. Leprosy patients are characterized by different immune responses in different clinical forms. We investigated a possible association of the +874 polymorphism and CA repeats present in the first intron of IFN-γ with susceptibility to leprosy and with the manifestation of the different clinical forms. Nucleotide sequencing was performed with samples from 108 leprosy patients and 113 controls subjects, as well as immunophenotyping of CD(4)(+), CD(8)(+) and CD(69)(+) T cells by flow cytometry. The data showed that there were no significant differences between patients and control subjects, as well as according classification of Ridley-Jopling. However, the A/A genotype was significantly increased in paucibacillary patients (p=0.028) and the microsatellite encoding 16 CA repeats were significantly associated with paucibacillary compared to multibacillary patients (p=0.019). Individuals homozygous for the +874 A allele, the mean level of CD(4)(+) and CD(69)(+) T cells was higher. Our data suggest that polymorphisms present in the first intron of IFN-γ are not associated with susceptibility to leprosy, nevertheless, the +874 polymorphism and the CA repeats number encoded in IFN-γ gene may be related to a higher cellular immune response in patients and are consistently more frequently detected in PB patients.

    Full Text Available There are currently no available options to promote nerve regeneration through chronically denervated distal nerve stumps. Here we used a rat model of delayed nerve repair asking of prior insertion of side-to-side cross-bridges between a donor tibial (TIB nerve and a recipient denervated common peroneal (CP nerve stump ameliorates poor nerve regeneration. First, numbers of retrogradely-labelled TIB neurons that grew axons into the nerve stump within three months, increased with the size of the perineurial windows opened in the TIB and CP nerves. Equal numbers of donor TIB axons regenerated into CP stumps either side of the cross-bridges, not being affected by target neurotrophic effects, or by removing the perineurium to insert 5-9 cross-bridges. Second, CP nerve stumps were coapted three months after inserting 0-9 cross-bridges and the number of 1 CP neurons that regenerated their axons within three months or 2 CP motor nerves that reinnervated the extensor digitorum longus (EDL muscle within five months was determined by counting and motor unit number estimation (MUNE, respectively. We found that three but not more cross-bridges promoted the regeneration of axons and reinnervation of EDL muscle by all the CP motoneurons as compared to only 33% regenerating their axons when no cross-bridges were inserted. The same 3-fold increase in sensory nerve regeneration was found. In conclusion, side-to-side cross-bridges ameliorate poor regeneration after delayed nerve repair possibly by sustaining the growth-permissive state of denervated nerve stumps. Such autografts may be used in human repair surgery to improve outcomes after unavoidable delays.

    Full Text Available Objective: To study leprosy patients in tribal concentrated Bastar district of Chhattisgarh, India in terms of their knowledge, attitudes and the stigma they have experienced. Method: This cross-sectional study included 101 registered Leprosy patients, in a single leprosy treatment centre between April, 2012 - June, 2013. The data collection tool (a pre tested close-ended questionnaire was based on leprosy related socio-demographic variables, knowled geregarding different kinds of problems and issues experienced by the patients/participants. The investigators collected the data in face to face interviews and house hold visit. Results: Overall the majority of the respondents (85.1% were between 16 and 60 years of age. 74.3% were males, 80.2% were married, and 54.5% were literate. The majority (67.3% articulated positive knowledge about transmission of the disease, 75.3% knew that numbness of hands is an early symptom, 88.12% that it is curable, 91.1% had untreated deformities. Experiences reported included disturbed marital relationships (90.1% or social life (94.1%, loss of employment (54.5%, isolation with the sitation to talk to people (29.7%, family members not sharing food (94.1%; being forced to leave the family (54.45%. Health education interventions improved the knowledge of 91.1% of participants. Multi-Bacillary leprosy was higher in newly registered cases with higher disabilities in the hands and feet (60.4%, eyes (29.7%. 9.9% of WHO grade-2 disabilities were due to a delayed diagnosis. 67.5% of the patients/participants with some form of disability had experienced a delay in diagnosis up to 12 months. Conclusion: The study noted that the tribal people were affected by leprosy not only in terms of the physical problems, but also by the stigmatization that affects their social participation. These need to be addressed by the progress of the national leprosyp rogram.Keywords: Leprosy, social stigma, disability grading, India

    Full Text Available Citrus leprosis virus (C i LV was detected in Colombia at the eastern plains in 2004; it is a threat the disease spreads to other regions of the country. The main vector is Brevipalpus yothersi Baker (formerly identified as Brevipalpus phoenicis. This research determined the viability of B. yothersi to transmit C i LV to citrus plants, after been hosted in non-citrus plants. To virus acquisition, mites spent three days on symptomatic orange (Citrus x sinensis leaves positives to C i LV-C2; then mites were placed on six non-citrus plants (Dieffenbachia sp., Hibiscus rosa-sinensis,Codiaeum variegatum, Swinglea glutinosa, Sida acutaand Stachytarpheta cayennensis. A randomized design with 6 treatments and 4 replicates was carried out. After scheduled time in non-citrus plants, mites were three days relocated on C. x sinensis healthy plants. Leaves of receptor plants, were evaluated to the occurrence or absence of symptoms and collected for RT-PCR tests. B. yothersi mites were able to transmit the C i LV virus over 85 % of Valencia orange plants (Citrus x sinensis L., after feeding from 2-20 days on non-citrus host plants. The first leprosis symptoms on C. x sinensis leaves was confirmed from 14 to 51 days after transmission. The present research work further established that C i LV-C2 is a persistently transmitted virus. The implement quarantine diagnostic measures to prevent spread of CiLV to disease-free zones is suggested.

    Leprosy is one of the oldest diseases of humanity and persists as a serious public health problem. Brazil has the highest incidence and second highest prevalence. In the Americas, it accounts for 93% of the cases, according to World Health Organization data from 2008. The objective of this study was to ascertain the profile of leprosy patients in the municipalities of the Association of Municipalities of the Carboniferous Region (AMREC), over the period from January 1, 2001, to December 31, 2007. This was a retrospective cross-sectional study carried out in the AMREC region in Santa Catarina, Brazil. The sample was of census type, in which all the patients notified were analyzed. 54 patients were analyzed, among whom 57% were female and 42.6% were male. The most prevalent age group was from 30 to 39 years old (31.5%) and 79.6% had white skin color. The occupation was unknown in 51 cases, as was bacilloscopy in 98%. The tuberculoid and Virchowian forms each presented a frequency of 27.8%. The coefficient of detection observed in the municipalities ranged from low to very high. Neither multibacillary nor paucibacillary forms predominated in the analysis, nor any specific clinical form. Nevertheless, it is known that cases are being diagnosed late because of the low percentage of indeterminate cases, with predominance among females. Added to this, the information on the notification forms is sparse, which makes it impossible to show the realities of the study population.

    A review of the case files of 194 leprosy patients registered at a representative skin and venereal diseases out-patient clinic was done to assess the epidemiological and clinical patterns of the disease in Yemen. Almost all patients came from the poorer social groups and there was clustering of patients around some families. About 55% of the patients were aged 20 to 39 years and about 35% were aged over 40 years at the time of detection. Males were affected about three times as females; in males MB cases occurred about twice as often as PB cases and 12% of the cases presented as pure neuritic leprosy. Reactions were noticed in 39 cases (20%), six having type 1 and 27 having type 2 reaction. Bacterial index (BI) among 123 positive cases ranged from 0.1 to 6, about 70% of these cases showing mean BI of more than 2.0. Patients' response to treatment (MDT) was very good and BI decreased by about 1.55 (+/-0.05) logs per year. About 50% of the patients had some disability (14% grade 1), and the disability rate among PB cases was about 70%. Our findings indicate the need for earlier diagnosis and better disability preventive measures.

    Leprosy is a chronic disease caused by a bacillus Mycobacterium leprae and characterised by the formation of nodules or of macules that enlarge and spread accompanied by loss of sensation with eventual paralysis and production of deformities and mutilation. The wound of the disease can be treated by using conventional method such as Zinc Oxide (ZnO) Ointment with sterile gauze. Human amnion membranes have been used as a biological burn dressing with good results for several decades. A comparison study on using that conventional dressings and radiation sterilised lyophilised amnion membranes has been done at Sitanala Leprosarium to observe the effectiveness of using amnion membranes as leprosy wound dressing. Number of patients observed were 85, age from 12 to 60 years old. The locations of the wounds observed were at the leg and arm, with two types of wound i.e. reaction and simple ulcer. Parameter observed was the length of the healing time of the wounds. Results show that the average length of the healing time of the wound can be reduced from 64 days to 30 days when using amnion membranes compared to using the conventional wound dressing. The length of the healing time of the simple ulcer is longer that those of reaction wound using both of the dressings

  18. The colonial world as mission and mandate: leprosy and empire, 1900-1940.

    2000-01-01

    The history of medicine in twentieth-century empires has been dominated by studies of "imperial tropical medicine" (ITM) and its consequences. Historians have been fascinated by the work of medical scientists and doctors in the age of high imperialism, and there are many studies of medicine as a "tool of empire." This paper reviews work that explores colonial medicine as a broader enterprise than ITM in three spheres: missionary activity, modernization, and protection of the health and welfare of indigenous peoples. To illustrate the themes of mission and mandate, it discusses the development of policies to control leprosy in the tropical African and Asian colonies of Britain in the first half of this century, especially the work of the British Empire Leprosy Relief Association (BELRA). Although BELRA's efforts did little to change imperial medical and health agendas, they had an important impact locally and ideologically, and show how closely interwoven the themes of Christian caring, medical humanism, colonial development, and welfare policy had become by the outbreak of the Second World War.

    Decentralization policies are an integrated component of health sector reform in an increasing number of countries. The ability of such policies to improve the health system's quality and efficiency is backed up by limited scientific evidence. This study intends to evaluate the impact of decentralization on a specialized field of disease control (leprosy control) in Colombia and Brazil. It analyses the respective juridical base, epidemiological indicators and local publications. Furthermore, 39 semi-structured interviews with key informants were conducted. In both countries, the devolution of technical responsibility and financial resources to the municipalities was the implemented form of decentralization. Access to preventive and curative health care and the community participation in decision-making improved clearly only in Brazil. The decentralization to private providers in Colombia had dubious effects on service quality in general and still more on public health. The flow of finances (including finance collection through state-owned taxes instead of insurance companies) seemed to be better controlled in Brazil. Leprosy control in Brazil took advantage of the decentralization process; in Colombia, it came close to a collapse.

  1. Humanitarian quarantine in practice: medicine, religion and leprosy in New Caledonia.

    Sykes, Ingrid J

    2017-12-01

    Medicine and religion worked in close synchronisation during the leprosy outbreak of New Caledonia (1890-1950). Once isolation of leprosy-affected people became mandatory doctors and missionaries came together to promote a particular form of medical practice that tied charitable zeal with cutting-edge medical research, developing a sophisticated set of medical practices that catered for the soul as well as the body. Such practices went hand-in-hand with ideas developed by doctors in the earlier stages of the epidemic about the way in which the disease had entered the Kanak (local Melanesian) population. Doctors and missionaries admitted that immoral colonial channels had upset the delicate balance of local social and biological rhythms. Yet they also believed that the highly contagious nature of the outbreak was linked to the inferior state of Kanak. This paper aims to highlight the way in which the leprosaria system in New Caledonia represented a double-edged moral high-ground within the French medical colonial narrative. It tracks the complex way in which emotionally charged arguments about contagion, science and spirituality constructed an ideology of humanitarian quarantine which was used to justify a highly aggressive form of medical biocontrol.

    Full Text Available This article presents a case of relapse, with isolated neural manifestation, in a multibacillary patient previously treated with multidrug therapy for multibacillary leprosy (24 doses. The patient returned to the service six years after the end of treatment, with pain in hands and legs. He was investigated, and the serological monitoring showed an important increase in anti-phenolic glycolipid serum levels. A neural recurrence was suspected, since the patient had no new skin lesions. A new biopsy in the right ulnar nerve showed a bacilloscopy of 2 +, compatible with relapse. This is a literature review of the etiological, clinical, propedeutical and diagnostic aspects of this situation so poorly understood.O presente artigo relata um caso de recidiva, com manifestação neural isolada, em paciente multibacilar previamente tratado com poliquimioterapia para multibacilar 24 doses. O paciente retorna ao serviço, seis anos depois do fim do tratamento, com dores em mãos e pernas. Na investigação, o acompanhamento da sorologia anti-glicolipídeo fenólico 1 demonstrou aumento importante dos níveis séricos, e foi aventada a hipótese de recidiva neural, já que o paciente não apresentava lesões cutâneas novas. Uma nova biópsia, em nervo ulnar direito, demonstrou baciloscopia de 2+, compatível com recidiva.

    Aplasia of the optic nerve is an extraordinarily rare congenital anomaly that affects one or both optic nerves and is associated with the absence of the central retinal vessel and retinal ganglion cells. We report a case of unilateral optic nerve aplasia in a 4-month-old infant who was found to have left microphthalmos on routine postnatal checkup. Family history, antenatal history, and systemic evaluation were unremarkable. Magnetic resonance imaging showed absent left optic nerve with left microphthalmos. The optic chiasm was present and slightly deviated towards the right side. The remaining cerebral and ocular structures were normal.

    Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remains from 6th-8th century Northern Italy, 7th-11th century Hungary, 8th-9th century Austria, the Slavic Greater Moravian Empire of the 9th-10th century and 8th-10th century Byzantine samples from Northern Anatolia. These data were analyzed alongside findings published by others. M. leprae is an obligate human pathogen that has undergone an evolutionary bottleneck followed by clonal expansion. Therefore M. leprae genotypes and sub-genotypes give information about the human populations they have infected and their migration. Although data are limited, genotyping demonstrates that historical M. leprae from Byzantine Anatolia, Eastern and Central Europe resembles modern strains in Asia Minor rather than the recently characterized historical strains from North West Europe. The westward migration of peoples from Central Asia in the first millennium may have introduced different M. leprae strains into medieval Europe and certainly would have facilitated the spread of any existing leprosy. The subsequent decline of M. leprae in Europe may be due to increased host resistance. However, molecular evidence of historical leprosy and tuberculosis co-infections suggests that death from tuberculosis in leprosy patients was also a factor. Copyright © 2015 Elsevier B.V.

    To analyze a profile of patients treated at a national leprosy outpatient referral clinic in metropolitan Rio de Janeiro, Brazil, over a period of more than two decades, and the subgroup of nationally registered leprosy cases from the same residential area, as well as all registered cases statewide. An observational, descriptive analysis was carried out for patients treated from 1986 to 2007 at the Souza Araújo Outpatient Clinic (Ambulatório Souza Araújo, ASA), a national referral center for the diagnosis and treatment of leprosy at the Oswaldo Cruz Foundation (Fiocruz) that serves clients from the city of Rio de Janeiro and other municipalities in the metropolitan area of Rio de Janeiro State. Demographic and clinical data for the subgroup of leprosy cases registered with Brazil's National Disease Notification System (Sistema Nacional de Informação de Agravos de Notificação, SINAN) between 2001 and 2007 and residing in the same municipalities as the ASA patients, and for all registered cases statewide, were also analyzed. Among the ASA patients, there was a decrease in average family income (from 3.9 to 2.7 times the minimum salary between the periods 1998-2002 and 2003-2007); the proportion of multibacillary (MB) patients (from 52.7% to 46.9%); and the proportion of patients younger than 15 years old (from 12.8% to 8.7%). Among the MB patients, the average initial and final bacilloscopic indices were significantly higher in 2003-2007. Compared with the SINAN cases, more ASA cases involved disability and were younger than 15 years old. Patients living with leprosy in the metropolitan area of the state of Rio de Janeiro belong to the most deprived social strata and have not benefited from the overall improvement in socioeconomic conditions in Brazil.

    Full Text Available INTRODUCTION: Neural damages are among the main factors that contribute to physical disability in leprosy. Systematic monitoring using a broad physical, psychological and social approach is necessary. OBJECTIVE: The objective of this study was to characterize the limitation of activity and social participation and its correlation with disabilities and/or impairment in individuals after being discharged from a multidrug leprosy therapy. METHOD: A cross-sectional study conducted in Araguaína, state of Tocantins, which is a leprosy hyperendemic municipality. We included cases of patients who were discharged from treatment considered as cured from January 2004 to December 2009. We performed dermatological examination and applied the Screening Activity Limitation and Safety Awareness (SALSA and social participation scales. RESULTS: We included 282 individuals (mean age: 45.8 years old. The paucibacillary operational classification was more common (170; 60.3%. The eye-hand-foot score ranged from 0 to 12 (mean: 0.7. A total of 84 (29.8% individuals presented limited activity. A slight restriction in social participation occurred in 18 (6.3% cases. There was a statistically significant correlation between activity limitation, age (r = 0.40; p < 0.0001 and degree of functional limitation (r = 0.54; p < 0.0001, as well as of restricted social participation, activity limitation (r = 0.56, p < 0.0001 and functional limitations (r = 0.54, p < 0.0001. CONCLUSION: Functional limitation due to leprosy had an impact on the conduct of activities and social participation after the discharge from a leprosy treatment. The association between Screening of Activity Limitation and Safety Awareness and participation scales will assist in designing evidence-based assistance measures.

    Corticosteroids and/or thalidomides have been associated with thromboembolism events (TBE) in multibacillary (MB) leprosy. This report aimed to determine genetic and laboratory profiles associated with leprosy and TBE. Antiphospholipid antibodies (aPL), coagulation-related exams, prothrombin and Leiden's factor V mutations, and ß2-glycoprotein-I (ß2GPI) Val247Leu polymorphism were assessed. Six out of seven patients with leprosy were treated with prednisone and/or thalidomide during TBE and presented at least one positive aPL. All patients presented ß2GPI polymorphism, and one showed prothrombin mutation. Corticosteroid or thalidomide adverse effects and aPL and ß2GPI polymorphisms may cause TBE in patients with MB leprosy.

    Full Text Available ABSTRACT Objective In this study, we propose a modification to the simple decompression technique that contains the ulnar nerve in the cubital fossa, thus preventing subluxation during forearm flexion movements. Methods Five consecutive patients with leprosy-associated cubital tunnel syndrome underwent surgery with the modified technique between July 2011 and October 2012. Results The most common symptoms were neuropathic pain and sensory changes (both 60%. On the McGowan scale, three patients maintained their preoperative score and two patients improved by two points, while on the Louisiana State University Health Sciences Center scale, two patients maintained the same scores, two improved by two points, and one improved by one point. Four patients were able to discontinue corticosteroid use. The mean follow-up time was 25.6 months (range 2-48 months. There were no recurrences or subluxations in the long-term. Conclusion This alternative technique resulted in excellent functional results, as well as successful withdrawal from corticosteroids. Furthermore, it resulted in no ulnar nerve subluxations.

    The most common neurological defect in traumatic anterior glenohumeral dislocation is isolated axillary nerve palsy. Most recover spontaneously; however, some have persistent axillary neuropathy. An intact rotator cuff may compensate for an isolated axillary nerve injury; however, given the high rate of rotator cuff pathology with advancing age, patients with an axillary nerve injury are at risk for complete shoulder disability. To review reconstruction of the axillary nerve to alleviate shoulder pain, augment shoulder stability, abduction and external rotation to alleviate sole reliance on the rotator cuff to move and stabilize the shoulder. A retrospective review of 10 patients with an isolated axillary nerve injury and an intact rotator cuff who underwent a triceps nerve branch to axillary nerve transfer was performed. Patient demographics, surgical technique, deltoid strength, donor-site morbidity, complications and time to surgery were evaluated. Ten male patients, mean age 38.3 years (range 18 to 66 years), underwent a triceps to axillary nerve transfer for isolated axillary nerve injury 7.4 months (range five to 12 months) post-traumatic shoulder dislocation. Deltoid function was British Medical Research Council grade 0/5 in all patients preoperatively and ≥3/5 deltoid strength in eight patients at final follow-up (14.8 months [range 12 to 25 months]). There were no complications and no donor-site morbidity. A triceps to axillary nerve transfer for isolated axillary neuropathy following traumatic shoulder dislocation improved shoulder pain, stability and deltoid strength, and potentially preserves shoulder function with advancing age by alleviating sole reliance on the rotator cuff for shoulder abduction and external rotation.

    To evaluate the health-related quality of life (HRQL) in pediatric leprosy patients. A cross-sectional study included 47 leprosy patients and 45 healthy subjects. The HRQL was measured by Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0), and evaluated physical, emotional, social and school domains. The leprosy patients were classified by Ridley and Jopling classification criteria and assessed according to clinical musculoskeletal manifestations, laboratory and radiographic examinations. The median of current age was similar in leprosy patients and controls [12(6-18) vs. 15(5-18)years, p = 0.384], likewise the frequencies of female gender (p = 0.835) and middle/lower Brazilian socio-economic classes (p = 1.0). The domain school activities according the child-self report was significantly lower in leprosy patients compared to controls in the age group of 13-18 years [75(45-100) vs. 90(45-100), p = 0.021]. The other domains were alike in both groups (p > 0.05). At least one musculoskeletal manifestation (arthralgia, arthritis and/or myalgia) was observed in 15% of leprosy patients and none in controls (p = 0.012). Further comparison between all leprosy patients showed that the median of the physical capacity domain [81.25(50-100) vs. 98.44(50-100), p = 0.036] and school activities domain by child-self report [60(50-85) vs. 80(45-100), p = 0.042] were significantly lower in patients with musculoskeletal manifestations compared to patients without these manifestations. No differences were evidenced between the other HRQL parameters in both groups, reported by patients and parents (p > 0.05). Reduced physical capacity and school activities domains were observed in pediatric leprosy patients with musculoskeletal manifestations. Copyright © 2015 Elsevier Editora Ltda. All rights reserved.

    2001-11-01

    A neuroma of a calcaneal nerve has never been reported. A series of 15 patients with heel pain due to a neuroma of a calcaneal nerve are reviewed. These patients previously had either a plantar fasciotomy (n = 4), calcaneal spur removal (n = 2), ankle fusion (n = 2), or tarsal tunnel decompression (n = 7). Neuromas occurred on calcaneal branches that arose from either the posterior tibial nerve (n = 1), lateral plantar nerve (n = 1), the medial plantar nerve (n = 9), or more than one of these nerves (n = 4). Operative approach was through an extended tarsal tunnel incision to permit identification of all calcaneal nerves. The neuroma was resected and implanted into the flexor hallucis longus muscle. Excellent relief of pain occurred in 60%, and good relief in 33%. One patient (17%) had no improvement and required resection of the lateral plantar nerve. Awareness that the heel may be innervated by multiple calcaneal branches suggests that surgery for heel pain of neural origin employ a surgical approach that permits identification of all possible calcaneal branches.

    To assess the effectiveness of social skills training in leprosy patients to raise self-esteem and reduce self-perceived stigma. Five leprosy patients were given 10 day-long group-sessions of social skills training over 3 weeks. Training involved: identification of the emotions and concerns of patients when interacting socially; analysis of positive and negative social interactions and non-verbal and verbal skills training. Role-plays, videos and live models were used. Self-esteem and a reduction in self-perceived stigma were assessed qualitatively before and after training using semi-structured interviews. Assessment of change was scored under the indicators: self-perception, family, wider community and job. Patients were assessed for displaying new ways of interacting with people and changes in expectations for the future. Qualitative analysis of the interviews before and after training suggested that social skills training could raise the self-esteem of leprosy patients and combat self-perceived stigma. Increase in self-esteem, as evident through the verbal interactions with the interviewers and behavioural changes in the community, were noted in the majority of patients. Social skills training along with counseling may be able to increase the self-esteem of leprosy patients, and so be a useful part of leprosy rehabilitation schemes to try and combat the stigma of leprosy.

    After India and Brazil, Indonesia has the third highest incidence/prevalence of leprosy in the world. Every year thousands of new cases and case with grade-2 disability are reported and, while the recovery rate lingers only 80-90 %. Therefore, more than 10 % of leprosy patients drop out of treatment and can be a source of new infections in the community. Our research was aimed at determining apparent difficulties in the leprosy control program as well as how a health information system (HIS) could assist the Indonesian leprosy control program. We used qualitative method with deep interview and observation of document. One of the difficulties which the Indonesian leprosy control program faces is discontinuity of patient's data due to rotating staff as well as the treatment monitoring and queries patients which should be monitored after treatment has ceased. Technology implementation is feasible through short message service (sms) reminders and web base applications. The leprosy control program urgently needs to implement continuous monitoring and recording of patients because of the particular characteristics of this contagious disease.

    Full Text Available Leprosy is an infectious and contagious spectral disease accompanied by a series of immunological events triggered by the host response to the aetiologic agent, Mycobacterium leprae . The induction and maintenance of the immune/inflammatory response in leprosy are linked to multiple cell interactions and soluble factors, primarily through the action of cytokines. The purpose of the present study was to evaluate the serum levels of tumour necrosis factor (TNF-α and its soluble receptors (sTNF-R1 and sTNF-R2 in leprosy patients at different stages of multidrug treatment (MDT in comparison with non-infected individuals and to determine their role as putative biomarkers of the severity of leprosy or the treatment response. ELISA was used to measure the levels of these molecules in 30 healthy controls and 37 leprosy patients at the time of diagnosis and during and after MDT. Our results showed increases in the serum levels of TNF-α and sTNF-R2 in infected individuals in comparison with controls. The levels of TNF-α, but not sTNF-R2, decreased with treatment. The current results corroborate previous reports of elevated serum levels of TNF-α in leprosy and suggest a role for sTNF-R2 in the control of this cytokine during MDT.

    For the diagnostics of nerve lesions an imaging method is necessary to visualize peripheral nerves and their surrounding structures for an etiological classification. Clinical neurological and electrophysiological investigations provide functional information about nerve lesions. The information provided by a standard magnetic resonance imaging (MRI) examination is inadequate for peripheral nerve diagnostics; however, MRI neurography is suitable but on the other hand a resource and time-consuming method. Using ultrasonography for peripheral nerve diagnostics. With ultrasonography reliable diagnostics of entrapment neuropathies and traumatic nerve lesions are possible. The use of ultrasonography for neuropathies shows that a differentiation between different forms is possible. Nerve ultrasonography is an established diagnostic tool. In addition to the clinical examination and clinical electrophysiology, structural information can be obtained, which results in a clear improvement in the diagnostics. Ultrasonography has become an integral part of the diagnostic work-up of peripheral nerve lesions in neurophysiological departments. Nerve ultrasonography is recommended for the diagnostic work-up of peripheral nerve lesions in addition to clinical and electrophysiological investigations. It should be used in the clinical work-up of entrapment neuropathies, traumatic nerve lesions and spacy-occupying lesions of nerves. (orig.)

    Individuals in contact with patients who have leprosy have an increased risk of disease exposure, which reinforces the need for chemoprophylactic measures, such as the use of rifampicin. The objective of the review was to synthesize the best available evidence regarding the effectiveness of rifampicin chemoprophylaxis for contacts with patients with leprosy, and to synthesize the best available evidence on the experience and acceptability of rifampicin chemoprophylaxis as reported by the contacts and health professionals involved in the treatment of leprosy or Hansen's disease. In the quantitative component, individuals in contact with leprosy patients were included. In the qualitative component, in addition to contacts, health professionals who were in the practice of treating leprosy were included. The quantitative component considered as an intervention rifampicin at any dose, frequency and mode of administration, and rifampicin combination regimens.The qualitative component considered as phenomena of interest the experience and acceptability of rifampicin chemoprophylaxis. The quantitative component considered experimental and observational studies whereas the qualitative component considered studies that focused on qualitative data, including but not limited to, designs such as phenomenology, grounded theory, ethnography and action-research. The quantitative component considered studies that reported on outcomes such as the development of clinical leprosy in the contacts of patients who had leprosy, incidence rates, adverse effects and safety/harmful effects of the intervention. A three-step strategy for published and unpublished literature was used. The search for published studies included: PubMed, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Scopus, Web of Science, National Institute for Health and Clinical Excellence, Latin American and Caribbean Health Sciences Literature; and Google Scholar and EVIPnet for unpublished

    Though the impact of social inequality on health conditions is widely known, its impact on the chronic and stigmatized disease, leprosy, has received little attention. Deformity sometimes leads to disabilities and to handicaps causing problems to the patient and his family. In this paper an attempt has been made to understand the impact of social inequality, prevalent in the form of the caste system in India on the deformed leprosy patients and on their families. This impact was examined in terms of the problems faced by the patients. A sample of 150 deformed patients and their families, drawn from two districts in Tamil Nadu, was selected for the study. About 57% of the deformed patients experienced their deformity as a handicap which caused social and economic problems while the rest did not. Of the three caste groups, the Lower Caste group experienced more severe economic problems while the Upper Caste group faced more social problems. The extent of acceptance of deformed patients in their family varied significantly among those facing and not facing problems due to their deformity. The deformed patients without any handicap were accepted in a large majority of their families (82%) regardless of their caste status. In contrast the deformed but handicapped patients were accepted differentially among the three caste groups with the Upper group accepting them in most of their families (80%) while in the Lower group much less number of families (54%) did. All the families of the deformed but not handicapped patients desired to keep their patients till their death irrespective of their caste status. On the contrary, while all the families in the Upper Caste group expressed their willingness to keep their handicapped patients in the family till their death, 10% in the Middle and 22% in the Lower Caste groups did not want to do so. This suggests the gradual marginalization, rejection and dehabilitation of the affected. Thus, one's caste status can be a broad indicator

  4. Vagus Nerve Stimulation.

    The vagus nerve stimulation (VNS) is an approach mainly used in cases of intractable epilepsy despite all the efforts. Also, its benefits have been shown in severe cases of depression resistant to typical treatment. The aim of this study was to present current knowledge of vagus nerve stimulation. A new value has emerged just at this stage: VNS aiming the ideal treatment with new hopes. It is based on the placement of a programmable generator on the chest wall. Electric signals from the generator are transmitted to the left vagus nerve through the connection cable. Control on the cerebral bioelectrical activity can be achieved by way of these signal sent from there in an effort for controlling the epileptic discharges. The rate of satisfactory and permanent treatment in epilepsy with monotherapy is around 50%. This rate will increase by one-quarters (25%) with polytherapy. However, there is a patient group roughly constituting one-thirds of this population, and this group remains unresponsive or refractory to all the therapies and combined regimes. The more the number of drugs used, the more chaos and side effects are observed. The anti-epileptic drugs (AEDs) used will have side effects on both the brain and the systemic organs. Cerebral resection surgery can be required in some patients. The most commonly encountered epilepsy type is the partial one, and the possibility of benefiting from invasive procedures is limited in most patients of this type. Selective amygdala-hippocampus surgery is a rising value in complex partial seizures. Therefore, as epilepsy surgery can be performed in very limited numbers and rather developed centres, success can also be achieved in limited numbers of patients. The common ground for all the surgical procedures is the target of preservation of memory, learning, speaking, temper and executive functions as well as obtaining a good control on seizures. However, the action mechanism of VNS is still not exactly known. On the other hand

    Nineteen patients with isolated suprascapular entrapment neuropathy were seen between 1980 and 1986. A neurogenic cause and absence of other deficits were confirmed by electromyography. Electroneurographic tests were performed in 13 and demonstrated delayed conduction time and (or) reduction in stimulus response amplitude. In 16 patients there was an acute or chronic mechanical cause (direct pressure on the suprascapular nerve, forced dislocation of the shoulder blade). Two types of paralysis could be distinguished, an upper one affecting both the infra- and the supraspinatus muscles (12 patients), and a lower one involving only the infraspinatus muscle (4 patients). In two patients an inflammatory cause was considered likely, while in one the cause remained unclear. Restricting movement brought about an improvement in most patients, while in one the neurophysiological parameters improved after neurosurgical intervention, without complete clinical restoration.

    Full Text Available The leprosis disease shows a viral etiology and the citrus leprosis virus is considered its etiologic agent. The disease may show two types of cytopatologic symptom caused by two virus: nuclear (CiLV-N and cytoplasmic (CiLV-C types. The aim of this study was to compare the morpho-anatomical differences in the lesions caused by leprosis virus-cytoplasmic and nuclear types in Citrus sinensis (L. Osbeck 'Pêra'. Leaf and fruit lesions were collected in Piracicaba/São Paulo (cytoplasmic type and Monte Alegre do Sul/São Paulo and Amparo/São Paulo (nuclear type. The lesions were photographed and then fixed in Karnovsky solution, dehydrated in a graded ethylic series, embedded in hydroxy-ethyl methacrylate resin (Leica Historesin, sectioned (5 μm thick, stained and mounted in synthetic resin. The digital images were acquired in a microscope with digital video camera. Leaf and fruit lesions caused by the two viruses were morphologically distinct. Only the lesion caused by CiLV-N virus presented three well-defined regions. In both lesions there was the accumulation of lipidic substances in necrotic areas that were surrounded by cells with amorphous or droplets protein. Only leaf and fruit lesions caused by CiLV-N virus exhibited traumatic gum ducts in the vascular bundles.A doença leprose dos citros tem etiologia viral sendo o citrus leprosis virus seu agente etiológico.

    In response to an international strategy to prioritise and focus research efforts in leprosy, this conceptual protocol outlines a research plan to address key translational research priorities. The protocol describes in broad terms a five-phase psychosocial and service-related research programme to facilitate: prevention of delay in diagnosis, improvement of adherence with multi-drug therapy, the roll out of chemoprophylaxis and increased participation in community based rehabilitation. The protocol proposes a model of research utilisation and the notion of complexity to form an integrating theoretical framework for exploring and enhancing research translation. The proposed sequential research programme is characterised by traditional and participatory strategies, culminating in participatory implementation of findings. Publication of the conceptual protocol prior to operationalisation and commencement of the research aims to encourage debate, refinement of strategies, collaboration and the optimisation of resources.

    Based on the theories of social representation (SC) and Central Core (CC), a structural study was undertaken regarding the neologism hanseniase (Hansen's disease), the term adopted by Brazil's Ministry of Health in the 1970s. Carried out during 2001, this study interviewed eight hundred housewives residing in the Rio de Janeiro and Duque de Caxias municipalities. It found that Hansen's disease is part of a process of modernization of common thinking, anchored in the additional representation of leprosy. This finding is understandable from the perspective that the central structure of a social representation has a historical determination, so short -and middle-term changes are not to be expected. Furthermore, there has been no ongoing investment in social marketing to make the new terminology more widely known. The authors discuss the relation between social representation and the concept of the history of mentalities.

    In the submitted review the author deals with the development of peripheral nerve surgery (PN) from ancient times to the present time incl. hithero unpublished details. He analyses in great detail the period of the last 40 years which is divided into three stages--the mechanical, biological period and the period of neurotrophism. From the Second World War to the sixties the period bears the term mechanical. The results of reinnervation during this period were not satisfactory as the nerves were connected without the use of a microscope, in major defects they were connected under considerable traction and the only criterion was the resistance against dehiscence. Significant improvement of results of regeneration of PN was recorded during the biological period. Mechanical ideas were overcome and biological and physiological reactions of the peripheral nerves were taken into account. Suture of nerves under traction was refuted and into clinical practice the surgical microscope, microsurgical technique and microsurgical autotransplantation with a nervous graft were introduced. The anatomical structure of the nerve with a plexiform pattern of the fascicles became however the limitation of surgical methods. After discovery of NGF (nerve growth factor) we can speak of the onset of a new period, neurotrophism. In laboratory experiments many substances are studied and theoretically new non-surgical possibilities how to promote regeneration lie ahead. However they cannot be applied yet in clinical practice. In injuries of peripheral nerves the only correct reconstruction method is still microsuture of the nerve and in case of losses microsurgical autotransplantation using a nerve graft.

  14. Molecular analysis of a leprosy immunotherapeutic bacillus provides insights into Mycobacterium evolution.

    Directory of Open Access Journals (Sweden)

    Niyaz Ahmed

    Full Text Available BACKGROUND: Evolutionary dynamics plays a central role in facilitating the mechanisms of species divergence among pathogenic and saprophytic mycobacteria. The ability of mycobacteria to colonize hosts, to proliferate and to cause diseases has evolved due to its predisposition to various evolutionary forces acting over a period of time. Mycobacterium indicus pranii (MIP, a taxonomically unknown 'generalist' mycobacterium, acts as an immunotherapeutic against leprosy and is approved for use as a vaccine against it. The large-scale field trials of this MIP based leprosy vaccine coupled with its demonstrated immunomodulatory and adjuvant property has led to human clinical evaluations of MIP in interventions against HIV-AIDS, psoriasis and bladder cancer. MIP, commercially available as 'Immuvac', is currently the focus of advanced phase III clinical trials for its antituberculosis efficacy. Thus a comprehensive analysis of MIP vis-à-vis evolutionary path, underpinning its immanent immunomodulating properties is of the highest desiderata. PRINCIPAL FINDINGS: Genome wide comparisons together with molecular phylogenetic analyses by fluorescent amplified fragment length polymorphism (FAFLP, enterobacterial repetitive intergenic consensus (ERIC based genotyping and candidate orthologues sequencing revealed that MIP has been the predecessor of highly pathogenic Mycobacterium avium intracellulare complex (MAIC that did not resort to parasitic adaptation by reductional gene evolution and therefore, preferred a free living life-style. Further analysis suggested a shared aquatic phase of MAIC bacilli with the early pathogenic forms of Mycobacterium, well before the latter diverged as 'specialists'. CONCLUSIONS/SIGNIFICANCE: This evolutionary paradigm possibly affirms to marshall our understanding about the acquisition and optimization of virulence in mycobacteria and determinants of boundaries therein.

    This study evaluates the outcome of axillary nerve injuries treated with nerve grafting. Thirty-six patients were retrospectively reviewed after a mean of 53 months (minimum 12 months). The mean interval from injury to surgery was 6.5 months. Recovery of deltoid function was assessed by the power of both abduction and retropulsion, the deltoid bulk and extension lag. The deltoid bulk was almost symmetrical in nine of 34 cases, good in 22 and wasted in three. Grade M4 or M5* was achieved in 30 of 35 for abduction and in 32 of 35 for retropulsion. There was an extension lag in four patients. Deltoid bulk continued to improve with a longer follow-up following surgery. Nerve grafting to the axillary nerve is a reliable method of regaining deltoid function when the lesion is distal to its origin from the posterior cord.

    Full Text Available Nerve sheath myxoma has been described as a rare neural tumor arising from Schwann cells. It is observed most frequently in the central area of the face, neck and upper extremities. In the past the term neurothekeoma was used as synonym for nerve sheath myxoma but according to new reports, they are separate entities which can be confirmed by immunohistochemistry as in our case. Oral involvement of this tumor is extremely rare. Here, we present an unusual case of nerve sheath myxoma in the mandible of a 22-year old female patient. This case appears to be the first myxomatous variant which is centrally located in the mandible.

    1999-01-01

    Full Text Available The authors studied 70 leprosy patients and 20 normal individuals, comparing the traditional sera collection method and the finger prick blood with the conservation on filter paper for specific antibodies against the native phenolic glycolipid-I (PGL-I from Mycobacterium leprae. The finger prick blood dried on filter paper was eluated in phosphate buffer saline (PBS containing 0.5% gelatin. The classical method for native PGL-I was performed for these eluates, and compared with the antibody determination for sera. It was observed that there is a straight correlation comparing these two methods; although the titles found for the eluates were lower than those obtained for serology. This blood collection method could be useful for investigation of new leprosy cases in field, specially in contacts individuals.

    Conclusions: In peripheral nerve repairing in children by using nerve conduits, the outcome has been widely effective even when dealing with mixed and motor nerve, thus nerve tubulization might be considered as an alternative to nerve grafting. Conversely, considering the uncertain result obtained in brachial plexus repairing, the conduits cannot be considered as afirst choice of treatment in brachial plexus reconstruction.

    The occurrence of leprosy has decreased in the world but the perspective of its elimination has been questioned. A proposed control measure is the use of post-exposure chemoprophylaxis (PEP) among contacts, but there are still questions about its operational aspects. In this text we discuss the evidence available in literature, explain some concepts in epidemiology commonly used in the research on this topic, analyze the appropriateness of implementing PEP in the context of Brazil, and answer...

    Background This study is about the contribution of occupational therapy inside a rehabilitation group, and we focus on the autonomy of patients with disabilities due to leprosy. There are few studies on the use of assistive technology by leprosy patients; to our knowledge, none of them aim to have a subjective approach of care. Our purpose was to analyze the repercussions of assistive technology on autonomy of care of the self in patients with sequels of leprosy. Methods A qualitative, descriptive exploratory study with a semi-structured interview and a field observation as a research method was conducted between November 2014 and February 2015 at a University Hospital in Rio de Janeiro. Findings Eight patients from the service of Occupational Therapy were interviewed, and 44 hours of observation were performed. Interviews followed a semi-structured script and a field journal was used to take notes. Analysis was conducted by the hermeneutic approach. Costs were obtained after a global cost analysis of the fixed and variable expenses and direct and indirect costs to the manufactured products with an amount of 100 dollars. Results were grouped according to the following categories: contribution of the adapted devices for the care of the self and feelings and sensations provoked by the use of self-help devices. The reports revealed feelings, perceptions and meaningful contents about the social, familiar and individual dimensions, also the stigma coupled with leprosy. However, forms of re-signification were elaborated. Conclusions Assistive technology empowers the subject to perform care of the self and promotes social inclusion. PMID:27124408

    The aim of the study was to investigate the internal consistency and screening properties of the General Health Questionnaire-12 (GHQ-12) and the Hospital Anxiety and Depression Scale (HADS) in Turkish patients with leprosy. The two screening instruments and a fully structured diagnostic interview (CIDI) were administered to 65 people drawn from all leprosy inpatient units in Turkey between March and June of 2001. The scales were evaluated using Cronbach's alpha and Receiver Operating Characteristics (ROC) analyses. For each scale, criterion validity was assessed for any psychiatric disorder, depressive disorder and anxiety disorder. The Cronbach alpha coefficients for the GHQ-12 and HADS were 0.84 and 0.81 respectively. For detecting any psychiatric disorder, the optimal cut-off for the GHQ-12 was 4/5 (sensitivity 0.82, specificity 0.62). The optimal cut-off for the HADS total score was 12/13 (sensitivity 0.80, specificity 0.77). The results indicate that the General Health Questionnaire-12 and Hospital Anxiety and Depression Scale have satisfactory internal consistency, and performed well to a similar extent for detecting psychiatric disorders in leprosy patients.

    Full Text Available This study discusses the diagnosis and detection of the new citrus leprosis virus cytoplasmic type 2 (CiLV-C2 in samples collected in Meta and Casanare States, using molecular techniques performed RT-PCR on plant tissue and mite vectors Brevipalpus phoenicis (Geijskes. RT-PCR tests were carry out using specific primers MP and CPG. The use of CPG primers allows the detection of CiLV-C2, in tissue plant samples with leprosis symptoms on fruits and leaves of Valencia orange (Citrus sinensis L. and Swinglea gluinosa Merr. leaves, which confirms the presence of this virus in Colombia. The MP primers did not detect the CiLV-C2 in any of performed tests. The RT-PCR technique allows detection of CiLV-C2 in samples of B. phoenicis mite vectors, with the specific CPG primers. Molecular detection of CiLV-C2 by RT-PCR technique is a fundamental tool for the virus diagnosis in Colombia, and should be used in diagnosis and prevention programs of citrus leprosis in the country.

    Background This paper assesses the impact of a counselling intervention on reducing leprosy-related stigma in Cirebon District, Indonesia. The unique features of this intervention are its rights-based approach, the underlying Cognitive Behavioural Therapy (CBT) model, the three types of counselling and the lay and peer counsellors who were involved. Methodology/principal findings Mixed methods (e.g. three scales, interviews, focus group discussions and reflection notes) were used to assess the impact of the intervention, which ran over a two-year period. There was a control area with no interventions. The study participants were people affected by leprosy and other key persons (e.g. family members). The sample size differs per method, for example, data regarding 67 counselling clients and 57 controls from a cohort, and notes from 207 counselling clients were examined. The notes showed that most clients faced stigma on a daily basis, whether internalized, anticipated and/or enacted. A significant reduction was found between the before and after total scores of the SARI Stigma Scale (p-value stigma, promoting the rights of people with leprosy and facilitating their social participation. More research is needed on how to create a more sustainable intervention, preferably structurally embedded in the health or social services. PMID:27959932

    OBJECTIVE The accessory nerve is frequently repaired or used for nerve transfer. The length of accessory nerve available is often insufficient or marginal (under tension) for allowing direct coaptation during nerve repair or nerve transfer (neurotization), necessitating an interpositional graft. An attractive maneuver would facilitate lengthening of the accessory nerve for direct coaptation. The aim of the present study was to identify an anatomical method for such lengthening. METHODS In 20 adult cadavers, the C-2 or C-3 connections to the accessory nerve were identified medial to the sternocleidomastoid (SCM) muscle and the anatomy of the accessory nerve/cervical nerve fibers within the SCM was documented. The cervical nerve connections were cut. Lengths of the accessory nerve were measured. Samples of the cut C-2 and C-3 nerves were examined using immunohistochemistry. RESULTS The anatomy and adjacent neural connections within the SCM are complicated. However, after the accessory nerve was "detethered" from within the SCM and following transection, the additional length of the accessory nerve increased from a mean of 6 cm to a mean of 10.5 cm (increase of 4.5 cm) after cutting the C-2 connections, and from a mean of 6 cm to a mean length of 9 cm (increase of 3.5 cm) after cutting the C-3 connections. The additional length of accessory nerve even allowed direct repair of an infraclavicular target (i.e., the proximal musculocutaneous nerve). The cervical nerve connections were shown not to contain motor fibers. CONCLUSIONS An additional length of the accessory nerve made available in the posterior cervical triangle can facilitate direct repair or neurotization procedures, thus eliminating the need for an interpositional nerve graft, decreasing the time/distance for regeneration and potentially improving clinical outcomes.

  12. Unilateral traumatic oculomotor nerve paralysis

    The present authors report a case of unilateral traumatic oculomotor nerve paralysis which shows interesting CT findings which suggest its mechanism. A 60-year-old woman was admitted to our hospital with a cerebral concussion soon after a traffic accident. A CT scan was performed soon after admission. A high-density spot was noted at the medial aspect of the left cerebral peduncle, where the oculomotor nerve emerged from the midbrain, and an irregular, slender, high-density area was delineated in the right dorsolateral surface of the midbrain. Although the right hemiparesis had already improved by the next morning, the function of the left oculomotor nerve has been completely disturbed for the three months since the injury. In our case, it is speculated that an avulsion of the left oculomotor nerve rootlet occurred at the time of impact as the mechanism of the oculomotor nerve paralysis. A CT taken soon after the head injury showed a high-density spot; this was considered to be a hemorrhage occurring because of the avulsion of the nerve rootlet at the medial surface of the cerebral peduncle.

    OBJECTIVE Spinal accessory nerve (SAN) injury results in a series of shoulder dysfunctions and continuous pain. However, current treatments are limited by the lack of donor nerves as well as by undesirable nerve regeneration. Here, the authors report a modified nerve transfer technique in which they employ a nerve fascicle from the posterior division (PD) of the ipsilateral C-7 nerve to repair SAN injury. The technique, first performed in cadavers, was then undertaken in 2 patients. METHODS Six fresh cadavers (12 sides of the SAN and ipsilateral C-7) were studied to observe the anatomical relationship between the SAN and C-7 nerve. The length from artificial bifurcation of the middle trunk to the point of the posterior cord formation in the PD (namely, donor nerve fascicle) and the linear distance from the cut end of the donor fascicle to both sites of the jugular foramen and medial border of the trapezius muscle (d-SCM and d-Traps, respectively) were measured. Meanwhile, an optimal route for nerve fascicle transfer (NFT) was designed. The authors then performed successful NFT operations in 2 patients, one with an injury at the proximal SAN and another with an injury at the distal SAN. RESULTS The mean lengths of the cadaver donor nerve fascicle, d-SCM, and d-Traps were 4.2, 5.2, and 2.5 cm, respectively. In one patient who underwent proximal SAN excision necessitated by a partial thyroidectomy, early signs of reinnervation were seen on electrophysiological testing at 6 months after surgery, and an impaired left trapezius muscle, which was completely atrophic preoperatively, had visible signs of improvement (from grade M0 to grade M3 strength). In the other patient in whom a distal SAN injury was the result of a neck cyst resection, reinnervation and complex repetitive discharges were seen 1 year after surgery. Additionally, the patient's denervated trapezius muscle was completely resolved (from grade M2 to grade M4 strength), and her shoulder pain had disappeared

    Full Text Available The supracondylar humerus fracture (SCHF in children is common and can be complicated with nerve injury either primarily immediate post-trauma or secondarily posttreatment. The concept of neurapraxic nerve injury makes most surgeons choose to ‘watch and see’ the nerve recovery before deciding second surgery if the nerve does not recover. We report three cases of nerve injury in SCHF, all of which underwent nerve exploration for different reasons. Early reduction in the Casualty is important to release the nerve tension before transferring the patient to the operation room. If close reduction fails, we proceed to explore the nerve together with open reduction of the fracture. In iatrogenic nerve injury, we recommend nerve exploration to determine the surgical procedure that is causing the injury. Primary nerve exploration will allow early assessment of the injured nerve and minimize subsequent surgery.

    Background. Leprosy is a chronic infectious disease caused by the intracellular acid-fast bacilli Mycobacterium leprae; it has been determined that genetic factors of the host play an important role in the disease susceptibility. Thus, in this case-control study, we evaluated the possible association between the IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780) gene SNPs and susceptibility to leprosy disease in Mexican population. Methods. Seventy-five leprosy patients and sixty-nine control subjects were included. Both SNPs were genotyped with the polymerase chain reaction-restriction fragment length polymorphism technique. Results. We found nonsignificant differences in genotype and allele frequencies related to IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780) gene SNPs in MB as well as subclinical forms of leprosy disease versus healthy individuals. Conclusions. Since the sample size is not large enough, it is difficult to sustain an association of susceptibility to leprosy with genotypes or allele frequencies of IL-17A G-197A (rs227593) and IL-17F A7488G (His161Arg, rs763780), suggesting that IL-17 polymorphisms have no significant role in the genetic susceptibility to development of this disease in the Mexican Mestizo population.

    Because of the large numbers of leprosy patients with disability and the limited resources available, it is important that socio-economic rehabilitation (SER) is targeted towards those who are most in need. Towards this purpose, current assessments of leprosy patients prior to initiating SER include the evaluation of income, assets and household possessions. Conspicuously absent is the nutritional assessment of the patient. In the absence of weight loss associated with illness, population studies indicate that undernutrition reflects poor socio-economic conditions. In this study of 151 cured leprosy patients with disability, 57% of the patients were found to be undernourished using body mass index (kg/m2) derived from body weight and height, and 10% of the patients were severely undernourished (grade III). Undernutrition in the patients was poorly though significantly correlated with personal income (r = 0.18, P nutritional status evaluation by anthropometry as part of the initial screening of leprosy patients prior to instituting SER. We believe that this simple and objective evaluation can add to the assessment of 'threat' of economic deprivation or actual economic 'dislocation', and thus help in the prioritization of leprosy patients for SER.

    Background Can deliberate interaction between the public and persons affected by leprosy reduce stigmatization? The study described in this paper hypothesises that it can and assesses the effectiveness of a ‘contact intervention’. Methods/Principal Findings This cluster-randomized controlled intervention study is part of the Stigma Assessment and Reduction of Impact (SARI) project conducted in Cirebon District, Indonesia. Testimonies, participatory videos and comics given or made by people affected by leprosy were used as methods to facilitate a dialogue during so-called ‘contact events’. A mix of seven quantitative and qualitative methods, including two scales to assess aspects of stigma named the SDS and EMIC-CSS, were used to establish a baseline regarding stigma and knowledge of leprosy, monitor the implementation and assess the impact of the contact events. The study sample were community members selected using different sampling methods. The baseline shows a lack of knowledge about leprosy, a high level of stigma and contrasting examples of support. In total, 91 contact events were organised in 62 villages, directly reaching 4,443 community members (mean 49 per event). The interview data showed that knowledge about leprosy increased and that negative attitudes reduced. The adjusted mean total score of the EMIC-CSS reduced by 4.95 points among respondents who had attended a contact event (n = 58; p stigma against other neglected tropical diseases and conditions should be evaluated.

    Full Text Available A hanseníase é doença infecciosa milenar que, apesar da existência de terapêutica eficaz, ainda persiste como problema de saúde pública em seis países, entre eles o Brasil, líder mundial em prevalência da doença. Ao longo das últimas décadas, a hanseníase vem sendo estudada por perspectiva talvez inesperada para uma doença infecciosa: modernos métodos de análise experimental têm sido empregados para evidenciar a importância do componente genético no controle da susceptibilidade do hospedeiro à hanseníase e seus fenótipos. Esses estudos indicam que constituição genética favorável do hospedeiro, somada a fatores propícios, ambientais e relativos ao agente patogênico, tem alto impacto na definição da susceptibilidade tanto à infecção propriamente dita quanto à evolução clínica da doença. Hoje, diversos genes e regiões genômicas já foram relacionados ao controle da susceptibilidade à hanseníase. Outros estudos estão em andamento, visando ao avanço no entendimento das bases moleculares de controle da susceptibilidade do hospedeiro à doença. O conjunto de resultados desses estudos pode levar a formas mais eficazes de diagnóstico, tratamento e prevenção da hanseníase e outras doenças infecciosas.Leprosy is an ancient chronic infectious disease that, despite the existence of efficient therapy, still persists as a public health problem in six countries, including Brazil, the world leader in leprosy prevalence. During the past decades, leprosy has been studied from a somewhat unusual perspective for an infectious disease: modern methods for experimental analysis have been applied to demonstrate the existence of an important genetic effect controlling host susceptibility to leprosy and its phenotypes. These studies indicate that a favorable host genetic make-up, combined with environmental and pathogen-related variables, has a high impact on the definition of susceptibility to both infection and clinical

  20. Phrenic nerve transfer to the musculocutaneous nerve for the repair of brachial plexus injury: electrophysiological characteristics

    2015-01-01

    Full Text Available Phrenic nerve transfer is a major dynamic treatment used to repair brachial plexus root avulsion. We analyzed 72 relevant articles on phrenic nerve transfer to repair injured brachial plexus that were indexed by Science Citation Index. The keywords searched were brachial plexus injury, phrenic nerve, repair, surgery, protection, nerve transfer, and nerve graft. In addition, we performed neurophysiological analysis of the preoperative condition and prognosis of 10 patients undergoing ipsilateral phrenic nerve transfer to the musculocutaneous nerve in our hospital from 2008 to 201 3 and observed the electromyograms of the biceps brachii and motor conduction function of the musculocutaneous nerve. Clinically, approximately 28% of patients had brachial plexus injury combined with phrenic nerve injury, and injured phrenic nerve cannot be used as a nerve graft. After phrenic nerve transfer to the musculocutaneous nerve, the regenerated potentials first appeared at 3 months. Recovery of motor unit action potential occurred 6 months later and became more apparent at 12 months. The percent of patients recovering ′excellent′ and ′good′ muscle strength in the biceps brachii was 80% after 18 months. At 12 months after surgery, motor nerve conduction potential appeared in the musculocutaneous nerve in seven cases. These data suggest that preoperative evaluation of phrenic nerve function may help identify the most appropriate nerve graft in patients with an injured brachial plexus. The functional recovery of a transplanted nerve can be dynamically observed after the surgery.
