REVIEW
Francisco Javier Carod Artal
OBJECTIVES: To review infectious diseases that may cause autonomic dysfunction. METHODS: Review of published papers indexed in medline/embase. RESULTS: Autonomic dysfunction has been reported in retrovirus (human immunodeficiency virus (HIV), human T-lymphotropic virus), herpes viruses, flavivirus, enterovirus 71 and lyssavirus infections. Autonomic dysfunction is relatively common in HIV-infected patients and heart rate variability is reduced even in early stages of infection...

OBJECTIVE: To investigate the occurrence and clinical characteristics of dapsone-related adverse drug reactions (ADRs) among leprosy patients who underwent multidrug therapy (MDT) from 2010 to 2013 in the western region of Nepal. METHODS: A retrospective review was carried out in the rehabilitation center. Data were collected from the record files of the hospital. RESULTS: From 2010 to 2013, there were 18 patients reported to have dapsone ADRs, with an occurrence rate of 0...

AbstractErythema nodosum leprosum (ENL), also known as type II leprosy reaction, is a severe immune-mediated complication of multibacillary leprosy. For ENL, corticosteroids and thalidomide are the mainstays of treatment. Other immunosuppressants, such as clofazimine, cyclosporine, and azathioprine have also been used. Although most patients with ENL respond well to conventional treatments, a small number are refractory to these therapies and have severe morbidity or mortality. We report the case of a 24-year-old man with refractory ENL treated with high-dose corticosteroids for 15 months...

BACKGROUND: The study of past infectious diseases increases knowledge of the presence, impact and spread of pathogens within ancient populations. AIM: Polymerase chain reaction (PCR) was used to examine bones for the presence of Mycobacterium leprae ancient DNA (aDNA) as, even when leprosy is present, bony changes are not always pathognomonic of the disease. This study also examined the demographic profile of this population and compared it with two other populations to investigate any changes in mortality trends between different infectious diseases and between the pre-antibiotic and antibiotic eras...

The pathways that trigger exacerbated immune reactions in leprosy could be determined by genetic variations. Here, in a prospective approach, both genetic and non-genetic variables influencing the amount of time before the development of reactional episodes were studied using Kaplan-Meier survival curves, and the genetic effect was estimated by the Cox proportional-hazards regression model. In a sample including 447 leprosy patients, we confirmed that gender (male), and high bacillary clinical forms are risk factors for leprosy reactions...

The Horn of Africa suffers from a high prevalence of tuberculosis which is reported to be partly driven by multi-drug resistant (MDR) Mycobacterium tuberculosis strictu sensu strains. We conducted a prospective study to investigate M. tuberculosis complex species causing tuberculosis in Djibouti; along with their in vitro susceptibility to standard anti-tuberculous antibiotics, in addition to clofazimine, minocycline, chloramphenicol and sulfadiazine. Among the 118 mycobacteria isolates from 118 successive patients with suspected pulmonary tuberculosis, 111 strains of M...

BACKGROUND: Leprosy control is based on early diagnosis and multidrug therapy. For treatment purposes, leprosy patients can be classified as paucibacillary (PB) or multibacillary (MB), according to the number of skin lesions. Studies regarding a uniform treatment regimen (U-MDT) for all leprosy patients have been encouraged by the WHO, rendering disease classification unnecessary. METHODOLOGY AND FINDINGS: An independent, randomized, controlled clinical trial conducted from 2007 to 2015 in Brazil, compared main outcomes (frequency of reactions, bacilloscopic index trend, disability progression and relapse rates) among MB patients treated with a uniform regimen/U-MDT (dapsone+rifampicin+clofazimine for six months) versus WHO regular-MDT/R-MDT (dapsone+rifampicin+clofazimine for 12 months)...

Mycobacteria genus is responsible for deadly diseases like tuberculosis and leprosy. Cell wall of bacteria belonging to this genus is unique in many ways. It plays a major role in pathogenesis and intracellular survival inside the host. In intracellular pathogens, their cell wall acts as molecular shield and interacts with host cell milieu to modulate host defense responses. Unique role of cell wall associated factors that play crucial roles in the biosynthesis of mycobacterial cell wall components like Antigen 85 complex, Glycosyltransferases (GTs), LM (lipomannan) and LAM (lipoarabinomannan), mAGP Complex, lipolytic enzyme have been categorically documented...

Leprosy control has seen little innovation and only limited progress in the past decade. However, research on the disease has increased and important innovations are underway. Here, we comment on efforts to develop tools and approaches to detect leprosy and to stop the transmission of Mycobacterium leprae, the causative bacillus of the disease. The tracing and screening of contacts of known patients with leprosy promises to strengthen early diagnosis, while preventive chemotherapy will reduce the risk of contacts developing the disease by 50-60% within 2 years of administration...

Leprosy is present in more than 100 countries, where it remains a major cause of peripheral neuropathy and disability. Attempts to eliminate the disease have faced various obstacles, including characteristics of the causative bacillus Mycobacterium leprae: the long incubation period, limited knowledge about its mode of transmission, and its poor growth on culture media. Fortunately, the leprosy bacillus is sensitive to several antibiotics. The first antibiotic to be widely used for leprosy treatment was dapsone in the 1950s, which had to be taken over several years and was associated with increasing bacterial resistance...

Our previous study has demonstrated that IL-10 may modulate both indoleamine 2,3-dioxygenase (IDO) and CD163 expression in lepromatous leprosy (LL) cells, favoring Mycobacterium leprae persistence through induction of regulatory pathways and iron storage. Here, we observed that in LL lesion cells there is an increase in the expression of proteins involved in iron metabolism such as hemoglobin (Hb), haptoglobin, heme oxygenase 1 and transferrin receptor 1 (TfR1) when compared to tuberculoid leprosy (BT) cells...

OBJECTIVES: We wished to validate our recently devised 16-item ENLIST ENL Severity Scale, a clinical tool for measuring the severity of the serious leprosy associated complication of erythema nodosum leprosum (ENL). We also wished to assess the responsiveness of the ENLIST ENL Severity Scale in detecting clinical change in patients with ENL.

Tuberculosis (TB) and leprosy are two age-old infections, which we are facing even today. With drug-resistant TB on the rise, we report a case of multidrug-resistant TB with leprosy, which has never been reported previously. The peculiar course of this case forces us to rethink about the upcoming challenges due to their cooccurrence.

Antimicrobial molecules have been used for more than 50 years now and are the basis of modern medicine. No surgery can nowdays be imagined to be performed without antibiotics; dreadful diseases like tuberculosis, leprosis, siphilys, and more broadly all microbial induced diseases, can be cured only through the use of antimicrobial treatments. However, the situation is becoming more and more complex because of the ability of microbes to adapt, develop, acquire, and share mechanisms of resistance to antimicrobial agents...

Primary cutaneous aspergillosis is a rare disease, caused by organisms like Aspergillus flavus and Aspergillus fumigatus. Fine Needle Aspiration Cytology (FNAC) is a simple and well established tool for the diagnosis of mycotic infections. We report a case of forearm swelling that presented clinically as lipoma in a known case of lepromatous leprosy. It was diagnosed as primary cutaneous aspergillosis on FNAC, which was subsequently confirmed on culture. Cutaneous aspergillosis co-existing with leprosy has rarely been reported in the literature and early diagnosis of aspergillosis in immunocompromised patients is mandatory...

Leprosy is a chronic infectious disease that is caused by the obligate intracellular pathogen Mycobacterium leprae (M.leprae), which is the leading cause of all non-traumatic peripheral neuropathies worldwide. Although both myelinating and non-myelinating Schwann cells are infected by M.leprae in patients with lepromatous leprosy, M.leprae preferentially invades the non-myelinating Schwann cells. However, the effect of M.leprae infection on non-myelinating Schwann cells has not been elucidated. Lipid droplets (LDs) are found in M...
