SD-4 deficiency had no impact on the intrinsic T-cell response to TCR-induced signals, but enhanced these cells’

Sorafenib ic50 responsiveness to APC. Moreover, we showed SD-4 to be a constitutive inhibitor of allo-reactive T cells responsible for GVHD. Hence, SD-4 can be targeted to treat GVHD by increasing the efficacy of allo-HSCT therapy. Female BALB/c and C57BL/6 (6–8 weeks old) mice were purchased from Harland Breeders (Indianapolis, IN), and OT-II transgenic mice were purchased from Taconic Farms (Hudson, NY). Pmel-1 TCR transgenic mice (B6.Cg-Thy1a/CyTg(TcraTcrb)8Rest/J) were bought from Jackson Laboratory (West Grove, PA). SD-4-deficient mice were produced by mating SD-4+/− mice bearing a C57BL/6 genetic background.[14] We also produced SD-4-deficient pmel-1 mice by breeding SD-4−/− and pmel-1 transgenic mice. Control groups included mice with wild-type (WT) genotype (SD-4+/+) from the same generation of backcrosses. Following National Institutes of Health guidelines, mice were housed and cared for in a pathogen-free facility and subjected to experimental procedures approved by the Institutional Animal Care Use Center at The University of Texas Southwestern Medical Center (Dallas, TX). Monoclonal antibodies (mAb) against CD3 (145-2C11), CD4 (RM4-5), CD8 (53-6.7), CD11c (N418), CD19 (eBio 1D3), PD-1 (J43), Foxp3 (FJK-165) and H-2Kb-SIINFEKL (eBio25-D1.16) were purchased from eBioscience (San Diego, CA); mAb against

SD-4 (KY/8.2) were from BD Pharmingen (San Diego, CA); secondary antibodies were obtained from Jackson BAY 80-6946 mw ImmunoResearch (West Grove, PA); and hgp100 peptide (KVPRNQDWL), ovalbumin(257–264)

(OVA257–264) H-2Kb-restricted class I peptide (SIINFEKL), and OVA323–339 H-2Kb-class II peptide (ISQAVHAAHAEINEAGR) were synthesized by the Protein Chemistry Technology Center at UT Southwestern. For flow cytometry, lymph node cells or T cells (5 × 105 to 10 × 105) were treated with 5 μg/ml Fc blocker (BD Pharmingen) on ice for 30 min and incubated Edoxaban with primary antibody (5–10 μg/ml), followed by addition of secondary antibody (2·5 μg/ml). After washing, cell-bound fluorescence was analysed by FACSCablibur (BD Biosciences, San Jose, CA). DC-HIL-Fc, comprising the extracellular domain fused to the Fc portion of human IgG1, was produced in COS-1 cells and purified as described previously.[15] Purity of final preparations was high, as judged by a single band in SDS–PAGE/Coomassie Blue staining or in immunoblotting with anti-DC-HIL mAb or goat anti-human IgG antibody. CD3+, CD4+ and CD8+ T cells were purified from spleen using pan-T-cell, CD4+ and CD8+ T-cell isolation kits (Miltenyi Biotec, Auburn, CA), respectively, according to the manufacturer’s recommendations. For binding of DC-HIL-Fc to T cells,[6] CD4+ or CD8+ T cells (1 × 106) purified from spleens of WT or KO mice were activated by culturing with immobilized anti-CD3 antibody (1 or 3 μg/ml) for 3 days.

It recommends that not just age must be used as a predictor of poor QOL but also physical and mental functioning. This is important as some studies suggest that the physical

effects of deteriorating health are less important to satisfaction with life in older patients vs younger patients. 1. Service Provision The Canadian Society of Nephrology published guidelines for the management of CKD in 2008.[4] This document does not include learn more web-based protocols for management of patient symptoms but gives guidelines on how a programme should function. There is also a published article based on these guidelines[5] on the management of CKD including a section on conservative management stating the need for comprehensive, proactive management. The following summarizes the areas covered in the document Guidelines 3.3–3.6 Comprehensive Conservative Management. All are grade D, opinion guidelines This section, written in 2008, includes discussion on Time-limited trials of dialysis Prognostic tools Membership of an interdisciplinary team Need

Care of the imminently dying patients – availability of co-ordinated EOL care. These articles are potentially helpful when assessing personnel and material needs Suplatast tosilate Small molecule library research buy when initiating a conservative care programme. There is a special

emphasis on the need for a multi-disciplinary team to care for patients on the Supportive care pathway. 2. Initiation, withholding and withdrawal of dialysis The Renal Physicians Association (RPA)[6] and the UK Renal Association[7] both have guidelines around initiation, withholding and withdrawal of dialysis. In the USA, the RPA published Clinical Practice Guidelines on Shared Decision-Making in the Appropriate Initiation of and Withdrawal from Dialysis in 2010, jointly with the American Society of Nephrologists. These comprehensive guidelines present a position on aspects such as prognostication, conflict resolution and palliative care. They are presented as recommendations with accompanying explanations and references. These would be useful as a base for setting out guidelines for Identifying patients Estimating prognosis Appropriateness of withholding or withdrawing dialysis Provision of palliative care communication The UK guidelines are ‘Planning, Initiating and Withdrawal of Renal Replacement Therapy’.[8] The evidence for these recommendations has been assessed using the modified GRADE system which classifies expert recommendations (1 Strong, 2 Weak) and quality or level of evidence (A – High to D – very low). Guidelines 6.1–6.5 deal with EOL, conservative management and withdrawal of dialysis.

As severe dengue disease is associated with a second infection with a heterologous serotype of DENV, it would be of interest to determine the magnitude, quality, serotype specificity and enhancing activity of antibodies generated following a second infection with other serotypes and strains of DENV. There is variability in the infection rate and immunological responses detected in BLT-NSG mice. We were unable to find

a correlation between the degree of reconstitution of hCD45+ cells in the blood before infection Caspase inhibitor and the ability of BLT-NSG mice to become productively infected (data not shown). Robust IgM immune responses also did not correlate with viral titres in these mice. Another limitation of the BLT-NSG model

is variable and low DENV-specific IgG responses, which may reflect multiple deficiencies in this model. The inability of mouse cytokines such as B-lymphocyte-stimulating factor to signal effectively to human B cells in the xenogeneic environment may account for poor B-cell development.26,32 Generation of B-lymphocyte-stimulating factor-transgenic NSG mice is currently underway and should enhance both human B-cell and T-cell immune function in humanized mice. Human IgG concentrations in the serum are on average lower in BLT-NSG mice compared with human adults.33,34 Inadequate T-cell help and lack of human follicular dendritic cell engraftment may also contribute to ineffective class switching in these mice. Providing adequate human HLA expression as well as supporting CT99021 in vitro B-cell maturation by addition of human stromal cells with follicular dendritic cell engraftment differentiation capacity should lead to improved humoral responses. We have begun to phenotype human B cells in engrafted BLT-NSG mice and speculate that poor IgG production may be related to high frequencies of immature B cells in the periphery, as Thymidylate synthase has been

shown by other groups.35,36 Biswas et al.37 indicate that 50% of the human B cells in the periphery, but not in the bone marrow, also express the CD5 antigen, which is found only infrequently on mature follicular B cells in humans. Immunization with recombinant viral envelope antigens (HIV-gp140 and West Nile virus envelope proteins) stimulated production of antigen-specific human antibodies to West Nile virus and HIV gp140 that were predominantly of the IgM isotype. Transgenic expression of human-specific molecules and cytokines should better recapitulate immune responses observed in immunocompetent individuals.11,24 In conclusion, we have demonstrated improved DENV-specific adaptive immune responses in BLT-NSG mice. There are still some limitations with current models and further improvement in human engraftment and DENV-specific immune responses are required before these models can be used routinely and reproducibly in vaccine development.

Act1−/− mice displayed a similar skewing in the repertoire from T1 to T2/T3 B cells as previously described for BALB/C.Act1−/− mice (Fig. 5D and Supporting Information GW-572016 datasheet Fig. 4) [2]. Interestingly, also TCRβ/δ−/− mice showed elevated levels of T2 and to a lesser extend T3 B cells, suggesting that either (i) B cells accumulated

at the immature stage due to lack of additional T-cell-driven differentiation factors or (ii) that TCRβ/δ−/− mice expressed increased BAFF production and thus enhanced T2/T3 B-cell survival. It should also be noted that despite variable numbers of total transitional T1, T2, and T3 B cells, the ratios of T2:T1 and T3:T1 B cells were consistently increased in all gene-deficient mice (TCRβ/δ−/−, B6.Act1−/−, and TKO) as compared with WT mice (Fig. 5E). Based on these data, we evaluated if T-cell deficiency affected BAFF signaling. We first tested mice for expression levels of TACI and BAFF-R on spleen-derived transitional

B cells. In correlation with our previous observation [2], T1 and T2/T3 B cells from all strains expressed comparable levels of BAFF-R and TACI (Fig. 6A). We then tested levels of serum BAFF and found that B6.Act1−/− mice expressed levels similar to WT mice, while T-cell-deficient mice (TCRβ/δ−/− as well as TKO) displayed increased levels of BAFF (p < 0.0001, as compared with WT and B6.Act1−/−, respectively) (Fig. 6B). These data suggest that the increased levels Akt inhibitor of T2/T3 B cells observed in T-cell-deficient mice could in fact be driven by excess BAFF. Finally, accumulation of MZ B cells is a common readout in autoimmune mouse models and has been attributed a significant role in driving autoantibody production [29-31]. We tested spleen samples for numbers of MZ B cells (B220+AA4.1−CD21+CD23low) by flow cytometry. Deficiency in either T cells (TCRβ/δ−/−) or Act1 (B6.Act1−/−) resulted in significantly increased levels of MZ B cells (p < 0.05 versus WT, Fig 7). Combined deficiency in TKO mice did not result in further increases. BAFF-Tg

Megestrol Acetate mice are known to develop a SLE-like disease independently of T cells [17]. Act1 is well established as a negative regulator of BAFF signaling, and thus we expected the auto-immune phenotype of B6.Act1−/− mice to be T-cell independent as well. Upon analyzing T-cell-deficient B6.Act1−/− mice, it became clear that while all IgG-related abnormalities were absent in TKO mice, IgM-related autoimmune characteristics, including IgM anti-nuclear autoantibodies and IgM-IC deposition in kidney glomeruli, were retained or even elevated in these mice. Both TCRβ/δ−/− and TKO mice experienced similarly elevated IgM levels within the kidney glomeruli, that is, the deposition was not dependent on Act1-deficiency and did not correlate with specific levels of anti-nuclear IgM autoantibodies.

[17-19] Similarly, the PKC family has been shown to have a nuclear function as epigenetic enzymes.[20, 21] In human T lymphocytes, Sutcliffe et al. demonstrated that nuclear-anchored PKCθ forms an active transcription complex with RNA polymerase II (Pol II), the histone kinase MSK1, the adaptor molecule 14-3-3ζ and the lysine demethylase, LSD1 on key immune-responsive gene promoters (Fig. 3).[21] Further results also suggest that the recruitment of PKCθ to coding genes depends

on nuclear factor-κB signalling.[22] These epigenetic modifiers therefore clearly work in co-operation with other modifiers, transcription factors and the transcription machinery. Therefore future research needs to focus on the complexes of effector enzymes that form on chromatin to better understand the impact of histone modifications on gene transcription. In addition to the histone-modifying https://www.selleckchem.com/products/AZD6244.html enzymes, a group of chromatin-remodelling complexes have been described that physically alter chromatin structure and function.[23] These complexes contain a central ATPase component that harnesses

ATP hydrolysis to physically remove or slide histones from DNA. The chromatin-remodelling complexes are categorized into four distinct groups based on the sequence homology of their ATPase subunit: ISWI (Imitation SWItch), INO80/SWR1 (INOsitol requiring/Sick With Rat8 ts), CHD (chromodomain helicase Forskolin mw DNA binding protein) and SWI/SNF (SWItch/Sucrose Non-Fermentable). The Ergoloid best characterized of these complexes is the multi-subunit SWI/SNF complex, which contains either Brm (Brahma) or BRG1 (Brahma-related gene 1) as its ATPase subunit.[24] These ATPases are

able to act alone to remodel nucleosomes in vitro; however, within cells, they are found in complexes containing up to 12 additional proteins referred to as BAFs (BRG1/Brm-associated factors). These associated BAFs are proposed to modulate the targeting and functional specificity of the SWI/SNF complexes.[25, 26] The SWI/SNF complexes are thought to be targeted to specific genes through interactions with transcription factors, co-regulators or components of the transcription machinery. Whereas BRG1 has been found to interact with a range of transcription factors, it is likely that multiple interactions are involved in the recruitment of the SWI/SNF complex to any individual promoter.[27] In addition, several components of the SWI/SNF complex, including BRG1, have bromodomains, which recognize and bind to acetylated histones.[28] Therefore, acetylated histones can act as a platform for BRG1 recruitment, but it is most likely that other interactions are also required. Regardless of the mechanism, numerous studies have now demonstrated that the recruitment of SWI/SNF complex to a target gene reorganizes the associated chromatin, thereby influencing gene activity.

Myocarditis can

spontaneously resolve, but the primary long-term consequences are dilated cardiomyopathy (DCM) and heart Obeticholic Acid failure [1, 3]. The disease occurs most frequently in children and young adults, with 10–20% of sudden unexpected deaths being associated with myocarditis and DCM [4, 5]. Management of the disease suffers not only from insufficiently validated and established diagnostic procedures [6], but also from the lack of novel therapeutic options [3] such as immune-targeted therapies that are available for other inflammatory diseases [7, 8]. Thus, in order to target the critical effector pathways in inflammatory heart disease, it is important to resolve the molecular basis of the immune processes involved in the initiation of cardiac inflammation and the transition from myocarditis

to DCM. Cardiac inflammation in myocarditis/DCM is frequently triggered by infection with viruses or other microbial pathogens [2, 9, 10]. Both the infection itself and the resulting innate and adaptive immune responses may inflict significant damage to the myocardium. Rapid clearance of the pathogen will result in the resolution of the inflammation, whereas a failure in pathogen elimination and/or induction of chronic autoimmune reactions against cardiac antigens [11, 12] may foster the development of DCM. Several cardiac autoantigens that are targeted during chronic cardiac inflammation RO4929097 solubility dmso have been described, including β-1 adrenergic receptors [13], troponin-1 [14], and cardiac myosin [12, 15, 16]. The myosin heavy chain alpha (myhca) is expressed exclusively in the heart and contains a highly immunogenic epitope (myhca614–629) that causes myocarditis in susceptible mouse

strains [17]. Immunization with myhca protein [18] or peptide [17] leads to activation of heart-specific CD4+ T cells that elicit pronounced cardiac inflammation and thereby uncouples the autoimmune process from an infectious trigger. However, protein- or peptide-induced experimental autoimmune myocarditis (EAM) with complete Freund’s adjuvant (CFA) emulsified immunogens is a rather mild disease that completely 3-mercaptopyruvate sulfurtransferase resolves unless particular host factors such as IFN-γ [19], the IFN-γ receptor (IFNGR) [20], or IL-13 [21] are missing. Likewise, application of myhca614–629 via bone marrow derived dendritic cells (DCs) elicits only mild myocarditis, and progressive disease in this regimen can only be induced by additional application of myhca614–629 in CFA [22]. Thus, a model with spontaneous occurrence of myocarditis and progression to DCM that circumvents the strongly immune-biasing application of CFA or other adjuvants would permit a better resolution of the mechanisms underlying immune-mediated myocardial damage. T-cell receptor (TCR) transgenic animal models have greatly improved the understanding of the pathological principles of various inflammatory diseases including multiple sclerosis [23] and insulin-dependent diabetes mellitus [24].

The neuropathological

hallmarks of this type are: (i) a degenerated posterior column of the spinal cord; (ii) degeneration of Clarke’s column and the spinocerebellar tract; and (iii) Lewy body-like hyaline inclusions (LBHIs) in the remaining neurons.[2, 3] Approximately 20% of FALS cases are caused by mutations in the superoxide dismutase 1 (SOD1) gene.[1, 4] To date, 168 different SOD1 mutations have been reported (http://alsod.iop.kcl.ac.uk) to cause FALS, one being the well-known A4V mutation.[5, 6] The I113T mutation is also one of the common SOD1 mutations of FALS, having clinically variable phenotypic expression and low penetrance.[1, 7-9] In spite of progestogen antagonist several reports concerning mutations and clinical features, detailed clinico-neuropathological reports of FALS cases with this mutation are not so numerous. In fact, there have been only six autopsied cases with the I113T mutation reported.[10-14] Herein we report the seventh autopsied case of ALS with this I113T mutation. Although this case had no family history and presented a clinical course like that of SALS, neuropathological examination disclosed the presence of conglomerate inclusions (CIs), which are a feature of familial ALS with a SOD1 mutation. Aurora Kinase inhibitor Therefore, frozen-brain DNA of this

case was analyzed and shown to harbor the I113T SOD1 mutation. This case is the first showing both LBHIs and CIs in the motor neurons, in addition to the neurofibrillary tangles (NFTs) in the mesencephalic tegmentum. The patient had been healthy until the age of 64 years, when he noticed weakness in his arms and dyspnea upon exertion. Four months later he visited our hospital. Family history of neuromuscular diseases was negative. Upon neurological examination, weakness, muscle atrophy Montelukast Sodium and muscle fasciculations in the arms, legs and body trunk were noted. Deep tendon reflexes were hyperreactive in upper extremities, and plantar responses were bilaterally extensor. Dementia and parkinsonism were not seen. Eye movements were normal and no abnormality was found in other cranial nerves. The sensory system and bladder

function were intact. His relative vital capacity was decreased to 65.2%. A needle electromyograph (EMG) study revealed acute and chronic denervation in the extremities. The patient displayed lower motor-neuron signs in three regions and upper motor-neuron signs in two regions, and so he was diagnosed as probable ALS according to El Escorial’s criteria.[15] The weakness and dyspnea progressed rapidly, and he became unable to eat due to severe dyspnea 5 months after onset. He had repeated aspiration pneumonia and died of respiratory failure 7 months after onset. Autopsy was performed 5 h after death. The left tip of the frontal pole and a part of the spinal cord were frozen for biochemical analysis, and the rest of the brain and spinal cord were fixed in 10% neutral formalin and processed into paraffin sections.

Hence, intraorally, the pathogenic yeast may undergo a brief exposure to antifungal drugs. The objective of this study was to investigate the Selleckchem ICG-001 effect of brief exposure to sub-lethal concentrations of these antifungals on the germ tube formation and CSH of C. dubliniensis. After determining the minimum inhibitory concentration of the

drugs, 20 oral isolates of C. dubliniensis were exposed to sub-lethal concentrations of these antifungals for 1 h. Following this brief exposure, the drugs were removed, and following subsequent incubation in a germ tube inducing medium and exposure to bi-phasic hydrocarbon assay, the germ tube formation and CSH of these isolates was quantified respectively. Compared with controls, exposure to amphotericin B almost completely suppressed the ability to

form germ tubes with a mean percentage reduction of 95.91% (P < 0.0001), whereas ketoconazole and fluconazole also significantly inhibited germ tube formation but to a lesser degree with a mean percentage reduction of 18.73% and 12.01% respectively (P < 0.05). Compared with controls, exposure to amphotericin B and ketoconazole elicited a significant suppression on CSH with a mean percentage reduction PD0325901 mw of 33.09% and 21.42%, respectively (P < 0.001), whereas exposure to fluconazole did not elicit a significant suppression on CSH (9.21%; P > 0.05). In clinical terms it appears that, even a short exposure to sub-lethal concentrations of these drugs, a situation all too familiar in the oral environment, would continue to exert an antifungal effect by suppressing the pathogenic potency of C. dubliniensis. “
“Antimicrobial photodynamic therapy (aPDT) is an emerging alternative to treat infections based on the use of photosensitisers (PSs) and visible light. To investigate the fungicidal effect of PDT against azole-resistant Candida albicans strains using two PSs with a different mechanism of action, hypericin (HYP) and 1,9-dimethyl

methylene blue (DMMB), comparing their efficacy and the Ibrutinib research buy reactive oxygen species (ROS) species involved in their cytotoxicity. Azole-resistant and the azole-susceptible C. albicans strains were used. Solutions of 0.5 and 4 McFarland inoculum of each Candida strain were treated with different concentrations of each PS, and exposed to two light-emitting diode light fluences (18 and 37 J cm−2). Mechanistic insight was gained using several ROS quenchers. The minimal fungicidal concentration of HYP for ≥3 log10 CFU reduction (0.5 McFarland) was 0.62 μmol l−1 for most strains, whereas for DMMB it ranged between 1.25 and 2.5 μmol l−1. Increasing the fluence to 37 J cm−2 allowed to reduce the DMMB concentration. Higher concentrations of both PSs were required to reach a 6 log10 reduction (4 McFarland). H2O2 was the main phototoxic species involved in the fungicidal effect of HYP-aPDT whereas 1O2 was more important for DMMB-based treatments.

To explore the effect of TIPE2 in childhood asthma, we firstly detected the levels of TIPE2 mRNA and protein in PBMC of asthmatic children and normal controls. SAR245409 manufacturer The results showed both TIPE2 mRNA and protein in children with asthma were downregulated compared with healthy children. Now, the abnormal expression of TIPE2 has been found in several

human inflammatory diseases. It was reported that TIPE2 mRNA expression was significantly decreased in patients with SLE compared with healthy controls, and the TIPE2 mRNA expression levels negatively correlated with the SLE disease activity index (SLEDAI) and the myxoma resistance protein (MX1) mRNA expression levels in all the patients with SLE [7]. In addition, Xi W et al. [8] reported that patients with chronic hepatitis B had significantly reduced levels of TIPE2 expression in PBMC as compared to healthy individuals, and the TIPE2 expression negatively correlated with the blood levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (Tbil) as well as the HBV load of the patients. However, it has been found that TIPE2 expression was significantly increased in glomeruli from streptozotocin (STZ)-induced diabetic rats and renal biopsies of patients with diabetes [9]. Furthermore, Jia L et al. [23] found that the expression of TIPE2 in PBMC of chronic rejection group was significantly higher than that of the healthy control. The results suggest that

the abnormal expression of TIPE2 could participate in the pathogenesis AZD1152-HQPA cost of some chronic inflammatory diseases, but the mechanism may be different. The main immunological pathogenesis of asthma

is an imbalance in Th1 cell and Th2 cell. In this study, we measured the levels of Th1-type cytokine IL-4, Th2-type cytokine IFN-γ, serum total IgE and eosinophil count in patients with asthma and healthy controls. We found significantly higher levels of serum IL-4, IgE and eosinophil count, and lower Oxalosuccinic acid level of serum IFN-γ in asthmatic children, which suggests a Th2-dominated response in childhood asthma. These results were in line with the previous reports that elevated IL-4 and decreased IFN-γ protein secretion in allergic diseases were associated with overproduction of IgE and increase in eosinophil [24, 25]. To further determine the mechanism and significance of TIPE2 in patients with asthma, we analysed the correlations of TIPE2 mRNA expression with IL-4, IFN-γ, IgE and eosinophil count. The results showed obviously negative correlations of TIPE2 expression with IL-4, IgE and EO. Unfortunately, no statistically significant correlation was observed between TIPE2 and IFN-γ. It was reported that TIPE2 inhibited T cells activation through negatively regulating the TCR-mediated signalling pathway in mice, and purified T cells from TIPE2−/− mice were hyper-reactive to TCR ligation and produced significantly higher levels of Th17 cytokines as compared to WT controls [6].

[1, 2] However, it has also been described in patients with no underlying disease.[1, 2] The emergence of mucormycosis is being reported globally, with an alarming rise in the number of cases from developing countries including India.[1, 2, 4, 7-9] The precise epidemiology of this disease in developing world is not well known due to limited data as a result of sub-optimal awareness, inadequate reporting and diagnostic facilities at many of the healthcare centers.[1] However, the available literature suggests a considerable variation between the developing and developed nations, with differences in the prevalence, risk factors and causative agents involved.[1,

4-7] Certain peculiarities have been observed in cases of mucormycosis in India compared with the western world, including a high incidence of this disease; uncontrolled diabetes and diabetic ketoacidosis as the principal risk factor; rhino-orbito-cerebral

(ROC) form as the most LEE011 ic50 common clinical presentation; isolated renal mucormycosis as a new entity; and a wide and varied spectrum of pathogens involved in such infections.[1] Seasonal variations in incidence of mucormycosis with respect to temperature, rainfall and humidity have also been noted.[10] In this review, we highlight these distinct features of mucormycosis with reference to India. An upsurge of mucormycosis is being reported throughout the world over the past two decades, however, the rise in developing countries including India has been phenomenal.[1, 2, 4, 7-9] Three consecutive Selleck Talazoparib case series on mucormycosis have been reported from a single tertiary-care centre in India: 129 cases over 10 years (1990–1999), 178 cases during the subsequent 5 years (2000–2004) and then 75 cases in an 18 month period during 2006–2007.[4-6] Many other Indian centres have also subsequently published multiple series of this disease in different risk groups.[10-13] This increasingly high incidence of mucormycosis in India has been attributed primarily to a triclocarban continued increase in the patient population with uncontrolled diabetes, which is a one of the major risk factors for this disease in developing countries.[1] In fact, India has the second largest

diabetic population globally (65.1 million),[14] with nearly 70% of these cases being those of uncontrolled diabetes.[15] Environmental factors, such as tropical and sub-tropical humid climate and high environmental temperature in most parts of India, further provide an optimum set-up for survival of these fungi, and perhaps contribute to the disease prevalence.[1] Better awareness, expertise and diagnostic facilities in many of the healthcare centres have also significantly contributed to an increased recognition of this disease over the past years.[3] Majority of the reported cases from India have been those of proven mucormycosis, diagnosed based on culture and histopathology.[3] Very few authors have included probable mucormycosis in their series.
