Title: Associations between HLA-DRB1 alleles and leprosy in an Indonesian population. Source: Int. J. Lepr;65(2):190-196, Jun. 1997. tab. Abstract: To investigate whether the susceptibility to leprosy (type), subclinical infection with Mycobacterium leprae and the antibody response against M. leprae-specific antigens are associated with HLA-DR phenotypes sequence-specific oligonucleotide HLA-DRB1 and DQA1 typing and antibody assays have been performed in 79 leprosy patients (41 TT/BT and 38 LL/BL) and 50 healthy controls from a Javanese population in Yogyakarta, Indonesia. DRB1*02 was associated with LL/BL [odds ratio (OR) 2.54, 95% confidence interval (CI) 0.97-9.78, p = 0.037 and attributable risk (AR) 41.5%] but not with TT/BT leprosy (p > 0.05). HLA-DRB1*12 was negatively associated with leprosy (either LL/BL or TT/BT [OR 0.33-0.35, p < 0.05, prevented fraction (PF) 58.8%-65.3%]. No significant association was found between HLA-DRB1 or DQA1 type, anti-M. leprae antibody level and subclinical infection with M. leprae. These data indicate that in this population susceptibility to lepromatous leprosy is associated with HLA-DRB1*02, while resistance to leprosy is associated with HLA-DRB1*12. These associations are not paralleled with associations of the same HLA types with anti-M. leprae antibody level. Finally, the results of this study also support the notion that infection with M. leprae per se is not associated with HLA-DRB1 or DQA1 alleles. (AU)^ien.

Title: Humoral and cellular immune reactivity to recombinant M. leprae antigens in HLA-Typed leprosy patients and healthy controls. Source: Int. J. Lepr;65(2):178-189, Jun. 1997. tab, graf. Abstract: In our search for Mycobacterium leprae antigens that might specifically induce immunity or immunopathology, we have tested both humoral and cellular immune reactivity against purified recombinant M. leprae antigens in 29 paucibacillary (PB), 26 multibacillary (MB) leprosy patients, and 47 matched healthy contacts. The following M. leprae antigens were tested: 2L-1 (65L-1, GroEl-1), 2L-2 (65L-2, GroEl-2), 4L (SoDA), 43L, 10L (B) and 25L (Sra). The individuals were also typed for HLAD-RB1 and DQB1 in order to see whether leprosy status and/or immune reactivity to these antigens might be associated with certain HLA types. We also tested sera from another 48 patients before, during and after multidrug therapy (MDT) to study the relationship between antibody reactivity to recombinant M. leprae antigens and MDT. Antibody titers to the four recombinant M. leprae antigens tested and to D-BSA were higher in MB patients compared to PB patients and healthy controls, and declined with treatment. From a diagnostic or monitoring point of view none of the recombinant antigens seemed to be an improvement over D-BSA, mainly due to the lower sensitivity. IgG subclasses were measured in positive sera of untreated patients. These were mainly of the IgG1 and IgG3 subclasses, but subclass diversity was also observed and antigen dependent: all four subclasses could be detected against 10L (B), only IgG1 and IgG3 against 43L and only IgG1 against 25L and 2L-1. Cellular immune reactivity against the purified recombinant M. leprae antigens was measured in a lymphocyte stimulation test (LST). As for M. leprae, there was an inverse correlation between antibody and T-cell reactivity. However, the number of LST responders to recombinant antigens was much lower than to M. leprae. The 43L antigen was recognized most often (19%-24% of individuals tested) and more often than the 10L (B) antigen (10%-12%). No clear correlation was observed with leprosy type or protection and, in general, M. leprae nonresponders were also negative with recombinant antigens. Finally, we confirmed that HLA-DRB1*02 is associated with leprosy in this population, and we observed an association between DQB1*0601 and lepromatous leprosy. The number of positive individuals was too small to allow a meaningful analysis of the relationship between HLA type and immune reactivity. Although these data do not allow a conclusion as to one of these purified recombinant antigens being either protection or disease related, the antigen-dependent IgG subclass diversity warrants further study on antigen-specific qualitative differences in immune reactivity that may be relevant for the outcome of an infection with M. leprae.

Abstract: This study demonstrates that the platysma is occasionally palsied in leprosy and that this only occurs when the facial nerve already has some other palsy. That there needs to be a facial palsy before there can be a platysma palsy is strongly suggested, in that there was no case of an isolated platysma palsy. Patients, regardless of age or other factors, could mimic a platysma contraction. This obviates the need for electrical testing to examine for a platysma palsy. It also means that a nonfunctioning platysma on clinical examination is, in fact, a palsied platysma. While lagophthalmos is regularly examined for, and any obvious facial paresis would be noticed, less severe forms of facial muscle paresis will only be found if formally examined for. The mechanism whereby the facial nerve is involved in leprosy is not clarified, but our findings suggest that proximal spread of a lesion that began in the zygomatico-temporal branches and reaches to the facial nerve trunk is more likely than new lesions developing de novo in other peripheral facial nerve branches. That the primary lesion is within the facial nerve trunk in all cases but we only see the frequent zygomatic sequelae due to secondary factors is not excluded. (AU)^ien.

Title: Study of brain stem auditory-evoked potentials (BAEPs)and visual-evoked potentials (VEPs) in leprosy. Source: Int. J. Lepr;65(2):157-165, Jun. 1997. tab. Abstract: A study of brain stem auditory-evoked potentials (BAEPs) and visual-evoked potentials (VEPs) was done on 25 newly diagnosed patients with leprosy whose diagnosis was confirmed by skin biopsy. The results were compared with 25 age- and sex-matched healthy controls. In BAEPs the important observations were the prolonged latency of wave V in 13 (52%), delayed interpeak latency (IPL) of wave I-III in 5 (20%) cases, of wave III-V in 12/25 (40%), suggesting a conduction abnormality of the VIII cranial nerve in its peripheral part, in its nucleus and in its connection in the brain stem. In VEPs, a delayed peak latency of major positive potential (P100) was seen in 20 cases (80%; 11/13, 84.6% TT; 7/10, 70% LL; 2/2, 100% BL), suggestive of subclinical optic nerve involvement. The BAEPs and VEPs were both abnormal in 10 cases (40%; 3/13, 23% TT; 5/10, 50% LL; 2/2, 100% BL). Conduction abnormalities of the central nervous system (CNS) were observed more frequently in lepromatous leprosy, as in other forms of peripheral neuropathy such as hereditary motor sensory neuropathy type I (HMSN I). There is a fair possibility of similar multiple demyelinating lesions in the CNS also, as is seen in leprous peripheral neuropathy. This hypothesis requires further strengthening by an extensive study of multimodality evoked potentials with magnetic resonance imaging in the patients. Histopathological and immunofluorescent studies of autopsy material of the brain can also contribute significantly to solve the dilemma. (AU)^ien.

Title: Pathologic changes in a tibial nerve with surviving M. leprae in a healed tuberculoid leprosy patient. Source: Int. J. Lepr;65(1):90-94, Mar., 1997. tab. Abstract: A tibial nerve from a disease-arrested borderline tuberculoid (BT) leprosy patient was dissected out and examined almost in its entirety using hematoxylin and eosin staining, a modified Fite's stain for acid-fast bacilli (AFB), solochrome cyanin stain for myelin, and van Gieson's stain for fibrous tissue. Fibrosis of the perineurium and epineurium and fibrous replacement of the nerve parenchyma, which was maximum at the ankle joint area, were seen. In focal areas inflammation was present, especially in the epineurium around blood and lymph vessels. Even 21 years after adequate antileprosy therapy, AFB were present in the endoneurium in all except 2 of the 10 segments of the nerve, evoking hardly an inflammatory reaction or other ill effects. It is pointed out that BT leprosy should also be considered a generalized disease, especially when there is peripheral nerve trunk involvement and, in such cases, a longer duration of currently available antileprosy therapy is advisable. Trauma to nerve trunk plays a major role in producing nerve destruction and paralysis. (AU)^ien. Descriptors: Mycobacterium leprae/imunol Hanseníase Tuberculóide/imunol Location: BR191.1

Title: Differential development of CD4 and CD8 cytotoxic T cells (CTL) in PBMC across the leprosy spectrum IL-6 with IFN-gamma or IL-2 generate CTL in multibacillary patients. Source: Int. J. Lepr;65(1):45-55, Mar., 1997. tab, graf. Abstract: In the present study we evaluated the contribution of CD4 and CD8 T cells on the antigen-specific cytotoxic activity induced by whole Mycobacterium leprae in leprosy patients and normal controls (N) as well as the modulation of this activity by some cytokines. Peripheral blood mononuclear cells (PBMC) from N or from leprosy patients were stimulated with antigen in the presence or absence of cytokines for 7 days. M. leprae-stimulated PBMC were depleted of CD4 or CD8 antigen-bearing cells and employed as effector cells in a 4-hr [31Cr]-release assay against autologous M. leprae-pulsed macrophages. Our results demonstrate that both CD4 and CD8 T cells contribute to M. leprae-induced cytotoxic activity, with differences observed in paucibacillary (PB) and multibacillary (MB) patients. CD8-mediated cytotoxic activity is higher than that of CD4 cells in PB patients, while in MB patients CD4 cytotoxicity is predominant. Our data also demonstrate that the generation of CD4 and CD8 cytotoxic T lymphocytes (CTL) can be modulated differentially by interleukin-4 (IL-4), IL-6, gamma interferon (IFN-gamma), or IL-2. Although MB patients developed the lowest CTL response, cytokines such as IL-6 plus IL-2 or IFN-gamma were able to generate both CD4 and CD8 cytotoxic T cells from MB patients. In PB patients, IL-6 plus IFN-gamma displayed the highest stimulation on CD8 effector cells. Thus, an important role may be assigned to IL-6, together with IL-2 or IFN-gamma, in the differentiation of M. leprae-specific CTL effector cells. (AU)^ien.

Title: Daily multidrug therapy for leprosy; results of a fourteen-year experience. Source: Int. J. Lepr;65(1):37-44, Mar., 1997. graf. Abstract: Between 1980 and 1994, 67 new or relapsing leprosy patients were treated by daily administered multidrug regimens. Tuberculoid patients (23 TT/BT) received either bitherapy [rifampin + dapsone or clofazimine (RMP + DDS or CLO)] or tritherapy [RMP + DDS and/or CLO and/or ethionamide (ETH)] until clinical cure. Lepromatous patients (44 BB/BL/LL) received tritherapy (RMP + DDS and/or CLO and/or ETH) at least until bacteriological negativity. Of the 23 tuberculoid patients only one patient (5%) was cured at 6 months and about 70% needed between 6 and 24 months of treatment to obtain clinical cure (mean 19.5 months). In the 44 lepromatous patients, the achievement of bacteriological negativity was significantly linked to the initial bacterial index (BI), and it occurred after 2 to 7 years (mean 66.5 months) of multidrug therapy (MDT). The average BI decrease per year was 1.1+ during the first year, 0.9+ the second year, and then < 0.5+ per year. Reactional states significantly (p < 0.01) influenced the BI course: reversal reactions (RR) accelerated while erythema nodosum leprosum (ENL) delayed the BI decrease. Three of the 23 (13%) tuberculoid and 19 of the 44 (43%) lepromatous patients (p < 0.02) exhibited a RR and 18 of 44 (41%) lepromatous patients had ENL during MDT. A late RR (LRR) was observed in 1 (5%) and 6 (17%) of our tuberculoid and lepromatous patients, respectively, and 3 (8%) of our lepromatous patients suffered post-MDT ENL. No confirmed relapse has been observed within a follow-up period of 6 months to 7 years and 3 months [59 person-years at risk (PYR)] for TT/BT patients and of 4 months to 5 years and 10 months (100 PYR) for BB/BL/LL patients. When compared to the recommended WHO/MDT, it appears that daily MDT does not increase the clinical or the bacteriological cure rates either at 6 months in paucibacillary tuberculoid patients or at 2d years in multibacillary lepromatous patients. Moreover, as does the WHO/MDT, our regimens show a high frequency of reactional states both during and after treatment. This fact constitutes the main new problem of the actual treatment of leprosy.

Title: Low serum HDL-cholesterol is associated with raised tumor necrosis factor-alpha during ENL reactions. Source: Int. J. Lepr;65(1):1-11, Mar., 1997. tab, graf. Abstract: The concentrations of serum lipids and tumor necrosis factor (TNF) were measured in leprosy patients across the spectrum of the disease and in erythema nodosum leprosum (ENL) patients at the onset of the reaction and after the reaction had clinically subsided. Lepromatous/borderline lepromatous (LL/BL) patients had significantly higher serum triglyceride and lower HDL-cholesterol levels; there was no such change in the tuberculoid/borderline tuberculoid (TT/BT) patients. The household contacts (HC) of the LL/BL patients also had significantly lower serum HDL levels. ENL patients during the acute phase of the reaction had significantly lower total, LDL-, HDL-cholesterol levels compared to the stable LL/BL patients, and these changes were reversible to pre-ENL levels after the reaction had subsided. Serum TNF levels were significantly higher in household contacts and in LL/BL patients but were not statistically different in TT/BT patients. Serum TNF levels were also significantly higher during the acute phase of ENL, and declined after the clinical remission of the reaction to levels comparable with those of LL/BL patients. There was a significant negative correlation between serum TNF and HDL-cholesterol levels during and after ENL reaction. However, there was no such correlation between TNF and total or LDL-cholesterol levels in ENL patients. Our results suggest that the changes in HDL-cholesterol metabolism are a specific part of the host response to lepromatous leprosy and to the ENL reaction and may be mediated by increased TNF production.

Source: Int J Lepr;57(2):506-510, June 1989. ^bilus. Abstract: The dermal lymphatic vessels in lepromatous and tuberculoid leprosy lesions were studied by light- and electron-microscopy. In the lepromatous patient, lymphatic vessels were seen in both intra- and peri-granulomatous areas. The lymphatic lining cells contained lipid droplets, lysosomes, and numerous pinocytotic vesicles. Cells bearing bacilli were only occasionally seen. In the tuberculoid cases, lymphatic vessels were seen only along the edges of the granulomas and the lining cells were less prominent. Inflammatory cells, both lymphocytes and histiocytes, were found traversing the walls of lymphatic vessels in both groups of patients. The results of the study confirm the continued and increased functioning of the lymphatic drainage system in dermal leprosy lesions, and indicates that it may be a major route for the clearance of lipids from the lipid-rich bacilliferous lesions in the lepromatous patient. The lymphatic pathway appears to be a minor pathway for the dissemination of Mycobacterium leprae in comparison with the blood vascular system^ien.

Source: Int J Lepr;57(2):499-505, June 1989. ^bilus. Abstract: Liver function tests and liver biopsies were studied in 23 leprosy patients in reaction and 10 without reaction. The liver biopsies in leprosy patients with reaction showed exudative lesions, epithelioid and tuberculoid granulomas, and foam-cell granulomas. Portal vasculitis was encountered in a few cases. Neutrophilic infiltration into the foam-cell granulomas was seen in a few cases of lepromatous (LL) leprosy with reaction. In six cases of borderline (BL, BB and BT) leprosy with reaction, a spectrum of lesions bearing footprints of exudative lesions were seen evolving into epithelioid-cell granulomas. Foam-cell granulomas and tuberculoid and epithelioid granulomas along with exudative lesions were encountered in two cases on individual biopsy strips. An altered albumin-to-globulin ratio was the chief functional derangement observed in these cases. The spectrum of changes observed in borderline leprosy with reaction could be discrete steps in the evolution of upgrading reaction^ien.

Title: Studies of human leprosy lesions in situ using suction induced blisters 1. Cellular components of new, uncomplicated lesions. Source: Int J Lepr;57(2):492-498, June 1989. ^btab, ^bgraf. Abstract: The cellular contents of blisters induced by suction over new, uncomplicated leprosy lesions, and in the skin of cured, control patients, have been examined with enzyme- and immuno-histochemical staining over a period of 4 days. The total cellularity of the blisters varied over a wide range, not correlated with the type of leprosy. Mononuclear cells predominated at all times studied, with nearly equal percentages of monocytes and T lymphocytes. The T-helper: suppressor ratio was significantly greater in BT than in BL and LL lesions at 48 hr. Suction blisters offer a painless, quantitative, reproducible, multiple-sampling method for obtaining cells from the cutaneous infiltrates of leprosy for phenotyping or functional analysis^ien.

Abstract: The diagnosis of primary neuritic leprosy (PNL) and its differentiation from other causes of peripheral neuropathy is difficult since acid-fast bacilli (AFB) smears and skin biopsy are negative from anesthetic areas. A biopsy of the involved nerve is the only conclusive method of diagnosis. Such a biopsy may not necessarily be free of complications when a large nerve is involved. However, fine needle aspiration has in this study proved to be a simple technique to demonstrate inflammation granulomas and AFB from these involved nerves in 18 of the 27 cases suspected to have PNL. The validity of the cytological classification into morphological subtypes may have to be supplemented by a large series of studies. (AU)^ien.

Title: Induction of lepromin positivity and immunoprophylaxis in household contacts of multibacillary leprosy patients: a pilot study with a candidate vaccine, Mycobacterium w. Source: Int. J. Lepr;68(2):136-142, Jun., 2000. tab. Abstract: We screened 487 household contacts of multibacillary (MB) patients for evidence of disease and their lepromin status. From the 444 results available, 302 (68.02%) were lepromin positive and 142 (31.98%) were lepromin negative on initial testing. The initial lepromin status as assessed in the group of 54 contacts having disease at the outset showed 24 out of 46 (52.2%) to be lepromin positive and 22 of 46 (47.8%) to be lepromin negative. In the same group, among 24 lepromin positives, 22 (91.7%) had paucibacillary (PB) and 2 (8.3%) had multibacillary (MB) disease; among the lepromin negatives, 12 (54.5%) had PB and 10 (45.5%) had MB disease. Out of 72 initially lepromin-negative contacts administered Mycobacterium w vaccine and followed up, the cumulative percentages show that 53 (73.6%) converted to positivity after a single dose, 10 (87.5%) after a second dose and 67 (93.1%) after the third dose. The incidence of new cases with leprosy was 8 out of 231 (3.46%) among lepromin-positive contacts and 5 out of 93 (5.38%) among lepromin-negative contacts administered Mycobacterium w vaccine. Among 231 lepromin-positive contacts, the new cases occurred in those with a 1+ and 2+ lepromin response only, and no case occurred among 51 contacts with a 3+ lepromin response. The incidence among lepromin-positive contacts in this study (3.46%) was similar to the observations in two other studies: 3.2% by Dharmendra, et al. and 6.9% by Chaudhary, et al. However, the incidence among lepromin-negative contacts administered Mycobacterium w vaccine was significantly lower than that observed among lepromin-negative contacts not administered any vaccination in the other two studies (14.1% by Dharmendra, et al. and 29.0% by Chaudhary, et al.). To conclude, although a study of small sample size, the preliminary evaluation indicates that administration of Mycobacterium w vaccine seems to have the potential to reduce the incidence of leprosy among household contacts of leprosy patients. More explicit results about the vaccine will be available from the ongoing field trials in Kanpur Dehat in the near future. (AU)^ien.

S. Title: Single lesion paucibacillary leprosy: baseline profile of the Brazilian Multicenter Cohort Study. Source: Int. J. Lepr;68(3):247-257, Sept., 2000. tab, graf, mapa. Abstract: In Brazil, there is little information about the clinical and epidemiological characteristics of paucibacillary, single skin lesion leprosy patients (SSL-PB). Only recently has the official notification system distinguished leprosy patients with a single lesion as a clinical entity, for whom the single-dose ROM (rifampin, ofloxacin and minocycline) regimen has been recommended. In this paper, we describe the baseline clinical features and the immunological background of a multicenter cohort of SSL-PB leprosy cases enrolled between December 1997-1998. Patients were recruited at health centers located in the following regions: Southeast = Rio de Janeiro; North = Amazon and Rondônia states and Center-West = Goiás state. Eligible cases were newly detected, untreated single-lesion leprosy patients without thickened nerve involvement, and were assessed by clinical, bacilloscopic and histopathological exams. The Mitsuda skin test and anti-PGL-I serology (ELISA) were also performed. Of the 299 SSL-PB leprosy patients, 259 (86.6%) fulfilled the criteria for single-dose ROM intervention. Our results showed that patients recruited from different sites had similar features, considering the clinical and immunological profiles. There was a predominance of adults (mean age 32.4; S.D. = 16.0), and a BCG scar was detected in 76.7% of the children (< or = 15 years old). Only 7 cases were diagnosed as the multibacillary type, representing less than 3% of the patients being misclassified. Our data indicate that in Brazil SSL-PB case ascertainment based on clinical and bacilloscopic criteria can be accurately defined under a routine control program; 75.0% of SSL-PB cases were Mitsuda positive (> or = 5 mm) and seropositivity for anti-PGL-I was detected in 17.3% of the patients. These data are compatible with effective cell-mediated immunity and low bacillary load, suggesting favorable clinical outcomes for most SSL-PB participants of this cohort. (AU)^ien.
