Abstract
Disseminated mycobacterium avium complex (MAC) infection is rare and is classically associated with immunodeficient states. Osteomyelitis is a rare manifestation of disseminated MAC infection. The overwhelming majority of MAC infections occur in patients with human immunodeficiency virus (HIV). Disseminated MAC infection has been described in interferon gamma receptor deficiency, an immunodeficiency mechanistically linked to mycobacterial infection. We present a case of disseminated MAC vertebral osteomyelitis in a patient with interferon gamma receptor deficiency.

Abstract
Fungi are opportunists: They particularly require a defect of immunity to cause severe or disseminated disease. While often secondary to an apparent iatrogenic cause, fungal diseases do occur in the absence of one, albeit infrequently. These rare cases may be due to an underlying genetic immunodeficiency that can present variably in age of onset, severity, or other infections, and in the absence of a family history of disease. They may also be due to anti-cytokine autoantibodies. This review provides a background on how human genetics or autoantibodies underlie cases of susceptibility to severe or disseminated fungal disease. Subsequently, the lessons learned from these inborn errors of immunity marked by fungal disease (IEI-FD) provide a framework to begin to mechanistically decipher fungal syndromes, potentially paving the way for precision therapy of the mycoses.

Abstract
Objectives To help in diagnosis and treatment of adult-onset Mendelian Susceptibility to Mycobacterial Disease (MSMD). Methods We reported a 27-year-old man who had disease onset at 18 years. Then we reviewed previous reports of adult-onset MSMD patients, and summarized their clinical characteristics. Results The case was diagnosed as MSMD with tyrosine kinase 2 (TYK2) mutation and had dramatic improvement after treatment. In addition to our presented case and through a review of the literature, 12 cases in total were included in our study. Average age of disease onset was 29.4 years. Medium delay of diagnosis was 2.5 years. Four were with IFN-γR1 deficiency, four with IL-12β1 deficiency, two with NEMO deficiency, one with TYK2 deficiency and one with STAT1 deficiency. Common symptoms were lymphadenopathy (6/12, 50.0 %), weight loss (6/12, 50.0 %), bone/joint pain (5/12, 41.7 %), fever (4/12, 33.3 %) and gastrointestinal symptoms (4/12, 33.3 %). Mycobacteria caused infections in lymph nodes (7/12, 58.3 %), bone/joint (5/12, 41.7 %) and skin (5/12, 41.7 %). After treatment, eight (66.7 %) got favorable prognosis, two (16.7 %) died and one (16.7 %) was unknown. Conclusions Adult-onset MSMD have complex clinical presentations and are difficult to recognize, which results in delayed diagnosis. However, once identified, antibiotics and IFN-γ might have good efficacy. Therefore, when encountering adult patients with recurrent and refractory mycobacterial infections, especially in lymph nodes, bone/joints, and skin, MSMD should be considered.

Abstract
Atypical spinal infections (ASIs) of the spine are a challenging pathology to management with potentially devastating morbidity and mortality. To identify patients with atypical spinal infections, it is important to recognize the often insidious clinical and radiographic presentations, in the setting of indolent and smoldering organism growth. Trending of inflammatory markers, and culturing of organisms, is essential. Once identified, the spinal infection should be treated with antibiotics and possibly various surgical interventions including decompression and possible fusion depending on spine structural integrity and stability. Early diagnosis of ASIs and immediate treatment of debilitating conditions, such as epidural abscess, correlate with fewer neurological deficits and a shorter duration of medical treatment. There have been great advances in surgical interventions and spinal fusion techniques for patients with spinal infection. Overall, ASIs remain a perplexing pathology that could be successfully treated with early diagnosis and immediate, appropriate medical, and surgical management.

Abstract
Nontuberculous mycobacteria (NTM) rarely cause vertebral osteomyelitis; however, the clinical characteristics of vertebral osteomyelitis caused by NTM are poorly understood due to its rarity. A 74-year-old man with lung cancer was treated with prednisolone for immune checkpoint inhibitor-associated immune-related adverse events. He had been experiencing mild back pain without febrile episodes for five months, and was admitted to the hospital for worsening back pain and progressive paraplegia. Magnetic resonance imaging showed spinal cord compression at T4-5 due to fractures of the T5 and T7 vertebral bodies. The culture of a sample of pus from the T7 vertebral body obtained at the time of spinal fusion surgery yielded the Mycobacteroides abscessus (M. abscessus) complex. The patient was diagnosed with vertebral osteomyelitis caused by M. abscessus complex and treated with clarithromycin, amikacin, and imipenem; clarithromycin was later replaced by sitafloxacin because of inducible macrolide resistance. However, his neurologic deficits were irreversible, and he died due to a deteriorating general condition. The strain was identified up to subspecies level as M. abscessus subsp. abscessus by hsp65 and rpoB sequencing and nucleic acid chromatography. Although vertebral osteomyelitis due to NTM is rare, delayed diagnosis can lead to serious complications or poor outcomes. A prolonged clinical course, less frequent fever, vertebral destruction or spinal deformity, neurological deficits, or immunosuppressed conditions might be suggestive of NTM vertebral osteomyelitis.

J Allergy Clin Immunol 2021; 149:252-261.e6.

Abstract
BACKGROUND Patients with Mendelian susceptibility to mycobacterial disease (MSMD) experience recurrent and/or persistent infectious diseases associated with poorly virulent mycobacteria. Multifocal osteomyelitis is among the representative manifestations of MSMD. The frequency of multifocal osteomyelitis is especially high in patients with MSMD etiologies that impair cellular response to IFN-γ, such as IFN-γR1, IFN-γR2, or STAT1 deficiency. OBJECTIVES This study sought to characterize the mechanism underlying multifocal osteomyelitis in MSMD. METHODS GM colonies prepared from bone marrow mononuclear cells from patients with autosomal dominant (AD) IFN-γR1 deficiency, AD STAT1 deficiency, or STAT1 gain of function (GOF) and from healthy controls were differentiated into osteoclasts in the presence or absence of IFN-γ. The inhibitory effect of IFN-γ on osteoclastogenesis was investigated by quantitative PCR, immunoblotting, tartrate-resistant acid phosphatase staining, and pit formation assays. RESULTS Increased osteoclast numbers were identified by examining the histopathology of osteomyelitis in patients with AD IFN-γR1 deficiency or AD STAT1 deficiency. In the presence of receptor activator of nuclear factor kappa-B ligand and M-CSF, GM colonies from patients with AD IFN-γR1 deficiency, AD STAT1 deficiency, or STAT1 GOF differentiated into osteoclasts, similar to GM colonies from healthy volunteers. IFN-γ concentration-dependent inhibition of osteoclast formation was impaired in GM colonies from patients with AD IFN-γR1 deficiency or AD STAT1 deficiency, whereas it was enhanced in GM colonies from patients with STAT1 GOF. CONCLUSIONS Osteoclast differentiation is increased in AD IFN-γR1 deficiency and AD STAT1 deficiency due to an impaired response to IFN-γ, leading to excessive osteoclast proliferation and, by inference, increased bone resorption in infected foci, which may underlie multifocal osteomyelitis.

Abstract
BACKGROUND Bacillus Calmette-Guérin (BCG) vaccine is a live attenuated bacterial vaccine derived from Mycobacterium bovis, which is mostly administered to neonates in regions where tuberculosis is endemic. Adverse reactions after BCG vaccination are rare; however, immunocompromised individuals and in particular patients with primary immunodeficiencies (PIDs) are prone to develop vaccine-derived complications. OBJECTIVE To systematically review demographic, clinical, immunologic, and genetic data of PIDs that present with BCG vaccine complications. Moreover, we performed a meta-analysis aiming to determine the BCG-vaccine complications rate for patients with PID. METHODS We conducted electronic searches on Embase, Web of Science, PubMed, and Scopus (1966 to September 2018) introducing terms related to PIDs, BCG vaccination, and BCG vaccine complications. Studies with human subjects with confirmed PID, BCG vaccination history, and vaccine-associated complications (VACs) were included. RESULTS A total of 46 PIDs associated with BCG-VAC were identified. Severe combined immunodeficiency was the most common (466 cases) and also showed the highest BCG-related mortality. Most BCG infection cases in patients with PID were reported from Iran (n = 219 [18.8%]). The overall frequency of BCG-VAC in the included 1691 PID cases was 41.5% (95% CI, 29.9-53.2; I2 = 98.3%), based on the results of the random-effect method used in this meta-analysis. Patients with Mendelian susceptibility to mycobacterial diseases had the highest frequency of BCG-VACs with a pooled frequency of 90.6% (95% CI, 79.7-1.0; I2 = 81.1%). CONCLUSIONS Several PID entities are susceptible to BCG-VACs. Systemic neonatal PID screening programs may help to prevent a substantial amount of BCG vaccination complications.

Abstract
Background The interleukin-12 receptor β1 (IL-12Rβ1) deficiency is a primary immunodeficiency (PID), affecting the immunological pathway of interleukin 12/interferon- γ (IL12/IFN-γ) axis and interleukin 23 receptor (IL23R). Defect in this pathway is mainly affecting the cellular immunity-related disorders. IL-12Rβ1 is a receptor chain of both the IL-12 and the IL-23 receptors and thus, deficiency of IL-12Rβ1 abolishes both IL-12 and IL-23 signaling. Material and methods In this study, we performed whole exon sequencing and confirmatory Sanger sequencing in IL-12Rβ1. Evaluation of the IL12/IFN-γ axis was performed by assessment of patients’ whole blood cell to IL12/IFN-γ responding. Total and surface IL-12Rβ1expression was evaluated, in peripheral blood mononuclear cells (PBMCs) and T cell- derived PBMCs, and Th17 count was assessed. Results In the present study, we described a c.1791 + 2T > G mutation at a splicing site position in IL-12Rβ1, using whole exome sequencing, and confirmed with targeted Sanger sequencing in a 26- year-old patient with Mendelian susceptibility to mycobacterial disease (MSMD) and Crohn's disease (CD). Complete lack of IL-12Rβ1 protein expression was detected in patient's PBMCs, compared to the healthy control. Furthermore, no IL-12Rβ1 protein was expressed on the cell surface. Interestingly, IL-12Rβ1-mutant cells showed an impaired response to IL12, and Bacillus Calmette–Guérin stimulation, confirming that the mutation is causative in this patient. Conclusion A 3′splicing site mutation in IL12Rβ1, can be corresponding to the abolished expression of IL12Rβ1 in patients' cells, and associated with an impaired IL12-mediated signaling, which may lead not only to MSMD, but also to inflammatory bowel disease (IBD).

Abstract
PURPOSE Inborn errors of IFN-γ-mediated immunity underlie Mendelian Susceptibility to Mycobacterial Disease (MSMD), which is characterized by an increased susceptibility to severe and recurrent infections caused by weakly virulent mycobacteria, such as Bacillus Calmette-Guérin (BCG) vaccines and environmental, nontuberculous mycobacteria (NTM). METHODS In this study, we investigated four patients from four unrelated consanguineous families from Isfahan, Iran, with disseminated BCG disease. We evaluated the patients' whole blood cell response to IL-12 and IFN-γ, IL-12Rβ1 expression on T cell blasts, and sequenced candidate genes. RESULTS We report four patients from Isfahan, Iran, ranging from 3 months to 26 years old, with impaired IL-12 signaling. All patients suffered from BCG disease. One of them presented mycobacterial osteomyelitis. By Sanger sequencing, we identified three different types of homozygous mutations in IL12RB1. Expression of IL-12Rβ1 was completely abolished in the four patients with IL12RB1 mutations. CONCLUSIONS IL-12Rβ1 deficiency was found in the four MSMD Iranian families tested. It is the first report of an Iranian case with S321* mutant IL-12Rβ1 protein. Mycobacterial osteomyelitis is another type of location of BCG infection in an IL-12Rβ1-deficient patient, notified for the first time in this study.

Abstract
The integrity of the interferon (IFN)-γ circuit is necessary to mount an effective immune response to intra-macrophagic pathogens, especially Mycobacteria. Inherited monogenic defects in this circuit that disrupt the production of, or response to, IFN-γ underlie a primary immunodeficiency known as Mendelian susceptibility to mycobacterial disease (MSMD). Otherwise healthy patients display a selective susceptibility to clinical disease caused by poorly virulent mycobacteria such as BCG (bacille Calmette-Guérin) vaccines and environmental mycobacteria, and more rarely by other intra-macrophagic pathogens, particularly Salmonella and M. tuberculosis. There is high genetic and allelic heterogeneity, with 19 genetic etiologies due to mutations in 10 genes that account for only about half of the patients reported. An efficient laboratory diagnostic approach to suspected MSMD patients is important, because it enables the establishment of specific therapeutic measures that will improve the patient's prognosis and quality of life. Moreover, it is essential to offer genetic counseling to affected families. Herein, we review the various genetic and immunological diagnostic approaches that can be used in concert to reach a molecular and cellular diagnosis in patients with MSMD.

Abstract
Background Several case series have reported on clinical and radiographic characteristics of patients with vertebral osteomyelitis (VO) caused by non-tuberculous mycobacteria (NTM). However, only a few patients were included, and systematic reviews are still lacking. The aim of this study was to update and summarise the pre-disposing conditions, clinical and radiographic characteristics of such cases due to NTM. Methods In this study, a systematic review was conducted of the English-language literature from 1961-2014 to investigate the pre-disposing conditions and characteristics of cases of VO due to NTM. Also, six additional cases diagnosed in the study hospitals were described; these cases are included in an analysis of a total of 69 cases of NTM VO. Results The most common species, regardless of the presence of HIV co-infection, was M. avium Complex followed by M. xenopi. Ten cases with HIV infection had a median CD4 lymphocyte count of 320/mm(3) (range = 41-465/mm(3)) at the time of diagnosis of NTM VO. The VO in the cases with HIV infections occurred at an earlier age and more often involved the thoracic spine than in the cases without HIV infection. Pre-disposing trauma or surgery was reported in 14.5% (10/69) of the cases. A variety of immunosuppressive diseases were observed in 49.3% of the patients, including the 10 with HIV infections and corticosteroids were used in 27.5% of the cases. Surgery was performed in 67.6% and improvement was reported in 80.6%. Conclusion NTM should be considered in immunocompromised patients with indolent VO without confirmation of tuberculosis.

Abstract
Osteomyelitis caused by nontuberculous mycobacteria (NTM) can have severe consequences and a poor prognosis. Physicians therefore need to be alert to this condition, especially in immunocompromised patients. Although the pathogenesis of NTM osteomyelitis is still unclear, studies in immunodeficient individuals have revealed close relationships between NTM osteomyelitis and defects associated with the interleukin-12-interferon-γ-tumor necrosis factor-α axis, as well as human immunodeficiency virus infection, various immunosuppressive conditions, and diabetes mellitus. Culture and species identification from tissue biopsies or surgical debridement tissue play crucial roles in diagnosing NTM osteomyelitis. Suitable imaging examinations are also important. Adequate surgical debridement and the choice of appropriate, combined antibiotics for long-term anti-mycobacterial chemotherapy, based on in vitro drug susceptibility tests, are the main therapies for these bone infections. Bacillus Calmette-Guerin vaccination might have limited prophylactic value. The use of multiple drugs and long duration of treatment mean that the therapeutic process needs to be monitored closely to detect potential side effects. Adequate duration of anti-mycobacterial chemotherapy together with regular monitoring with blood and imaging tests are key factors determining the recovery outcome in patients with NTM osteomyelitis.

Abstract
Mendelian susceptibility to mycobacterial disease (MSMD) is a rare condition characterized by predisposition to clinical disease caused by weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria, in otherwise healthy individuals with no overt abnormalities in routine hematological and immunological tests. MSMD designation does not recapitulate all the clinical features, as patients are also prone to salmonellosis, candidiasis and tuberculosis, and more rarely to infections with other intramacrophagic bacteria, fungi, or parasites, and even, perhaps, a few viruses. Since 1996, nine MSMD-causing genes, including seven autosomal (IFNGR1, IFNGR2, STAT1, IL12B, IL12RB1, ISG15, and IRF8) and two X-linked (NEMO, and CYBB) genes have been discovered. The high level of allelic heterogeneity has already led to the definition of 18 different disorders. The nine gene products are physiologically related, as all are involved in IFN-γ-dependent immunity. These disorders impair the production of (IL12B, IL12RB1, IRF8, ISG15, NEMO) or the response to (IFNGR1, IFNGR2, STAT1, IRF8, CYBB) IFN-γ. These defects account for only about half the known MSMD cases. Patients with MSMD-causing genetic defects may display other infectious diseases, or even remain asymptomatic. Most of these inborn errors do not show complete clinical penetrance for the case-definition phenotype of MSMD. We review here the genetic, immunological, and clinical features of patients with inborn errors of IFN-γ-dependent immunity.

Abstract
Osteomyelitis due to Mycobacterium bovis Bacille Calmette-Guerin (BCG) often develops in patients with interferon-γ receptor 1 (IFNγR1) deficiency. In these patients, susceptibility appears to be caused by impaired interleukin-12- and IFNγ-mediated immunity. Here we report the case of a one-year-old girl with dominant partial IFNγR1 deficiency who suffered from lymphadenitis and multiple sites of osteomyelitis due to BCG infection. She was allergic to isoniazid and rifampicin--the prescribed standard treatment--and required prior desensitization therapy. She was subsequently treated with these drugs, but her symptoms did not improve. IFNγ therapy was added to the antitubercular therapy, increasing the serum level of IFNγ and leading to the resolution of the lymphadenitis and osteomyelitis. In conclusion, high dose IFNγ therapy in combination with antitubercular drugs led to resolution of BCG infection in a patient with dominant partial IFNγ deficiency.

Abstract
PURPOSE Poly-ostotic Langerhans Cell Histiocytosis (LCH) can be difficult to distinguish clinically and histologically from disseminated infection in manifesting specific subtypes of Mendelian Susceptibility to Mycobacterial Disease (MSMD). In MSMD-patients, dominant negative germline mutations in the IFN-γR1 gene, in particular in exon 6, lead to autosomal dominant IFN-γ receptor 1 deficiency (ADIFNGR1) and can mimic LCH. We hypothesized that similar defects might underlie the pathogenesis of LCH. METHODS IFN-γR1 expression was immunohistochemically determined at disease onset in biopsies from 11 LCH-patients and four ADIFNGR1-patients. IFN-γR1 function was analyzed in 18 LCH-patients and 13 healthy controls by assessing the IFN-γ-induced upregulation of Fc-gamma-receptor I (FcγRI) expression on monocytes. Pro-inflammatory cytokine production was measured after stimulation of whole blood with LPS and IFN-γ. Exon 6 of the IFN-γR1 gene was sequenced in 67 LCH-patients to determine whether mutations were present. RESULTS IFN-γR1 expression was high in three LCH-affected biopsies, similar to ADIFNGR1-affected biopsies, but varied from negative to moderate in eight other LCH-affected biopsies. No functional differences in IFN-γ signaling were detected between LCH-patients with active or non-active disease and healthy controls. No germline mutations in exon 6 of the IFN-γR1 gene were detected in any of the 67 LCH-patients. CONCLUSIONS In contrast to ADIFNGR1-patients, IFN-γ signaling is fully functional in LCH-patients. Either performed before, during or after treatment, these non-invasive functional assays can distinguish LCH-patients from ADIFNGR1-patients and thereby facilitate correct therapy regimens for patients with recurrent osteolytic lesions.

Abstract
Severe mycobacterial disease is mostly confined to patients who are immunocompromized either by acquired or inherited causes. One such genetic disorder is Mendelian Susceptibility to Mycobacterial Disease (MSMD), a hot topic within the field of primary immunodeficiency. This single gene disorder is characterized by isolated infection with mycobacteria or Salmonella due to a defect in the type-1 cytokine response. In the last two decades, ten genes have been labeled as causing MSMD when they harbor germline mutations, namely IL12B, IL12RB1, IFNGR1, IFNGR2, STAT1, IKBKG, CYBB, TYK2, IRF8 and ISG15. The mutations lead to either insufficient production of IFN-γ, or to an insufficient response to the cytokine. Current treatment options include recombinant IFN-γ and hematologic stem cell transplantation (HSCT). In the future, gene therapy, antisense-mediated exon skipping and chemical intervention in glycosylation problems may become successful alternatives. Furthermore, it is likely that many new candidate genes and pathways crucial for mycobacterial immunity will be identified.

Abstract
Understanding molecular immunity against mycobacterial infection is critical for the development of effective strategies to control tuberculosis (TB), which is a major health issue in the developing world. Host immunogenetic studies represent an indispensable approach to understand the molecular mechanisms against mycobacterial infection. A superb paradigm is the identification of rare mutations causing Mendelian susceptibility to mycobacterial diseases (MSMD). Mutations in the interferon-gamma (IFN-γ) receptor genes are highly specific (although not exclusive) for mycobacterial infection. Only dominant negative mutations of STAT1 have specific susceptibility to mycobacterial infection. Mutations in the interleukin-12 (IL-12) signaling genes have phenotypes with non-specificity. Current studies highlight a complex molecular network in antimycobacterial immunity, centered on IFN-γ signaling.

Abstract
IFN-gammaR1 deficiency is a genetic etiology of Mendelian susceptibility to mycobacterial diseases, and includes two forms of complete recessive deficiency, with or without cell surface expression, and two forms of partial deficiency, dominant or recessive. We report here a novel form of partial and recessive Interferon gamma receptor 1 (IFN-gammaR1) deficiency, which is almost as severe as complete deficiency. The patient is homozygous for a mutation of the initiation codon (M1K). No detectable expression and function of IFN-gammaR1 were found in the patient's fibroblasts. However, IFN-gammaR1 expression was found to be impaired, but not abolished, on the EBV-transformed B cells, which could respond weakly to IFN-gamma. The mechanism underlying this weak expression involves leaky translation initiation at both non-AUG codons and the third AUG codon at position 19. It results in the residual expression of IFN-gammaR1 protein of normal molecular weight and function. The residual IFN-gamma signaling documented in this novel form of partial IFN-gammaR1 deficiency was not ubiquitous and was milder than that seen in other forms of partial IFN-gammaR1 deficiency, accounting for the more severe clinical phenotype of the patient, which was almost as severe as that of patients with complete deficiency.

Abstract
Interferon (IFN) was originally identified as a substance 'interfering' with viral replication in vitro. The first IFNs to be identified were classified as type I IFNs (IFN-alpha/beta and related molecules), two other types have since been identified: type II IFN (IFN-gamma) and type III IFNs (IFN-lambda). Each IFN binds to one of three type-specific receptors. In the mouse model of experimental infections in vivo, IFN-alpha/beta are essential for immunity to most viruses tested, whereas IFN-gamma is important for immunity to a smaller number of viruses, together with bacteria, fungi, and parasites, consistent with IFN-gamma acting as the 'macrophage activating factor.' The precise role of IFN-lambda remains unclear. In recent years, inborn errors affecting the production of, or the response to, IFNs have been reported in human patients, shedding light onto the function of IFNs in natura. Disorders of IFN-gamma production, caused by IL12B, IL12RB1, and specific NEMO mutations, or of IFN-gamma responses, caused by IFNGR1, IFNGR2, and dominant STAT1 mutations, confer predisposition to mycobacterial disease in patients resistant to most viruses. By contrast, disorders of IFN-alpha/beta and IFN-lambda production, caused by UNC93B1 and TLR3 mutations, confer predisposition to herpes simplex encephalitis (HSE) in otherwise healthy patients. Consistently, patients with impaired responses to IFN-alpha/beta, IFN-gamma, and presumably IFN-lambda (carrying recessive mutations in STAT1), or with impaired responses to IFN-alpha/beta and impaired IFN-gamma production (carrying mutations in TYK2), or with impaired production of IFN-alpha/beta, IFN-gamma, and IFN-lambda (carrying specific mutations in NEMO), are vulnerable to mycobacterial and viral infections, including HSE. These experiments of nature suggest that the three types of IFNs play at least two different roles in host defense. IFN-gamma is essential for anti-mycobacterial immunity, whereas IFN-alpha/beta and IFN-lambda are essential for anti-viral immunity. Future studies in humans aim to define the specific roles of IFN-alpha/beta and IFN-lambda types and individual molecules in host defense in natura.

Abstract
Primary immunodeficiencies (PIDs) were long thought to be exclusively recessive traits -- autosomal recessive (AR) in most cases, with a few X-linked recessive (XR) diseases. In recent years, autosomal dominant (AD), mitochondrial, polygenic, and even somatic PIDs have been described. However, AR remains the most frequent inheritance pattern among recently described PIDs. Some PIDs have been shown to be genetically heterogeneous. Mendelian susceptibility to mycobacterial diseases (MSMD) displays a high level of genetic heterogeneity. There are 6 MSMD-causing genes, including 1 X-linked gene (nuclear factor-kappaB-essential modulator [NEMO]) and 5 autosomal genes (IFN-gamma receptor 1 [IFNGR1], IFN-gamma receptor 2 [IFNGR2], signal transducer and activator of transcription 1 [STAT1], IL-12 p40 subunit [IL12P40], and IL-12 receptor beta-subunit [IL12RB1]). The X-linked trait is XR; STAT1 deficiency is AD; the IFNGR2, IL12P40 subunit, and IL12RB1 deficiencies are AR; and IFNGR1 deficiency may be AD or AR. Two of the AR traits (IFNGR1, IFNGR2) may be subdivided into complete and partial deficiencies, and 3 AR complete deficiencies (IFNGR1, IFNGR2, IL12RB1) may be subdivided into disorders with and without cell surface expression. Finally, there are 2 types of AD STAT1 deficiency, depending on whether the mutation impairs phosphorylation or DNA binding. Thirteen genetic disorders conferring MSMD have been described, involving 1 XR, 3 AD (2 genes), and 9 AR traits (4 genes). However, no genetic etiology has yet been identified for about half of all patients with MSMD. We expect to identify new XR and AD causes of MSMD, but new AR etiologies of MSMD are also likely to be discovered. The investigation of children from areas in which consanguineous marriages are common will probably facilitate the description of many more AR traits.

Abstract
A yellow-pigmented, scotochromogenic, slowly growing mycobacterial strain, designated T1921(T), was isolated from the disseminated osteomyelitic lesions of a 7-year-old child with an underlying partial gamma interferon receptor alpha-1 deficiency. Hybridization by the line probe assay indicated the presence of a Mycobacterium species. Sequencing of the 16S rRNA gene, the internally transcribed spacer (ITS) region and the hsp65 and rpoB genes revealed that strain T1921(T) could be differentiated from all recognized species of the genus Mycobacterium. Phylogenetic analysis based on the 16S rRNA gene indicated that strain T1921(T) was related most closely to Mycobacterium intracellulare, whereas analysis based on the ITS and hsp65 and rpoB genes indicated that it was most closely related to Mycobacterium avium. Phenotypic tests were not able to differentiate strain T1921(T) from similar slowly growing mycobacteria. Strain T1921(T) is considered to represent a novel species of the genus Mycobacterium, for which the name Mycobacterium arosiense sp. nov. is proposed. The type strain is T1921(T) (=DSM 45069(T) =ATCC BAA-1401(T)).

Abstract
To investigate whether protective immune responses can be induced in the absence of normal interleukin-12/23/gamma interferon (IL-12/23/IFN-gamma) axis signaling, we vaccinated with the seasonal influenza virus subunit vaccine two patients with complete IL-12/23 receptor beta1 (IL-12/23R beta 1) deficiencies, two patients with partial IFN-gamma receptor I (pIFN-gamma RI) deficiencies, and five healthy controls. Blood samples were analyzed before, 7 days after, and 28 days after vaccination. In most cases, antibody titers reached protective levels. Moreover, although T-cell responses in patients were lower than those observed in controls, significant influenza virus-specific T-cell proliferation, IFN-gamma production, and numbers of IFN-gamma-producing cells were found in all patients 7 days after the vaccination. Interestingly, influenza virus-specific IFN-gamma responses were IL-12/23 independent, in striking contrast to mycobacterium-induced IFN-gamma production. In conclusion, influenza virus vaccination induces IL-12/23-independent IFN-gamma production by T cells and can result in sufficient humoral protection in both IL-12/23R beta 1- and pIFN-gamma RI-deficient individuals.

Abstract
BACKGROUND Atypical mycobacteria can cause systemic infections in patients with certain types of immunodeficiency. METHODS Clinical samples were decontaminated and cultured to assess the presence of mycobacterial species. Gene sequencing was performed to reveal interferon-gamma receptor 1 (IFN-gamma R1) deficiency. RESULTS The index patient received a diagnosis of dominant IFN-gamma R1 deficiency during treatment for a serious infection due to atypical mycobacteria. She belongs to a Norwegian multiplex family comprising 3 generations and 5 patients with dominant IFN-gamma R1 deficiency. Four of these patients have been treated with tuberculostatics because of extensive infection due to atypical mycobacteria, such as Mycobacterium avium-intracellulare, Mycobacterium scrofulaceum, Mycobacterium bovis (bacille Calmette-Guérin), Mycobacterium bohemicum, and Mycobacterium gordonae. Two of the patients have also received subcutaneous injections of IFN-gamma. One family member with the deficiency has not received treatment and is still healthy at 13 years of age. CONCLUSIONS Serious infection due to atypical mycobacteria should initiate a search for primary immunodeficiencies, particularly IFN-gamma R1 deficiency. Treatment with IFN-gamma should be started when serious infection due to atypical mycobacteria is verified and dominant partial IFN-gamma R1 deficiency is suspected.

Abstract
BACKGROUND Patients with interferon-gamma receptor 1 (IFNgammaR1) deficiency show selective susceptibility to intracellular pathogens such as mycobacteria. IFNgammaR1 deficiency is an inherited immunodeficiency disorder, which can be either recessive or dominant. Dominant forms of IFNgammaR1 deficiency are known to be associated with mutations that introduce a premature stop codon in the intracellular domain of IFNgammaR1. One such mutation, 818del4, is believed to be the most common type. Although these mutations are presumed to exert a dominant-negative effect on IFNgamma signal transduction, the underlying molecular mechanism is unresolved. OBJECTIVE We characterised the 774del4 mutant of IFNgammaR1 using a gene-expression system to examine the effects of this mutation on IFNgamma signal transduction. RESULTS We identified a novel dominant mutation in IFNGR1, designated 774del4, which produced a truncated form of IFNgammaR1 in a patient with recurrent mycobacterial infections. IFNgammaR1 was overexpressed on the surfaces of CD14-positive cells from the peripheral blood of this patient, and STAT1 phosphorylation in response to high doses of IFNgamma was partially deficient. We expressed two truncated forms of IFNgammaR1, 774del4 and 818del4, in HEK 293 cells using transient transfection and found that these mutants overexpressed IFNgammaR1 on the cell surface because of impaired receptor stability, which resulted in a dominant-negative effect on IFNgamma signal transduction. CONCLUSION Like the 818del4 mutation, 774del4 produces a truncated form of IFNgammaR1, which has a dominant-negative effect on IFNgamma signal transduction through altered receptor stability.

Abstract
In humans, genetic factors have long been suspected to contribute to the onset and outcome of tuberculosis. Such effects are difficult to identify owing to their complex inheritance, and to the confounding impact of environmental factors, notably pathogen-associated virulence determinants. Recently, forward genetic approaches in mouse models and in human populations have been used to elucidate a molecular basis for predisposition to mycobacterial diseases. The genetic dissection of host predisposition to infection with Mycobacterium bovis BCG and M. tuberculosis will help to define the key molecules involved in host antituberculous immunity and should provide new insights into this important infectious disease.

Abstract
Mendelian susceptibility to mycobacterial diseases confers predisposition to clinical disease caused by weakly virulent mycobacterial species in otherwise healthy individuals. Since 1996, disease-causing mutations have been found in five autosomal genes (IFNGR1, IFNGR2, STAT1, IL12B, IL12BR1) and one X-linked gene (NEMO). These genes display a high degree of allelic heterogeneity, defining at least 13 disorders. Although genetically different, these conditions are immunologically related, as all result in impaired IL-12/23-IFN-gamma-mediated immunity. These disorders were initially thought to be rare, but have now been diagnosed in over 220 patients from over 43 countries worldwide. We review here the molecular, cellular, and clinical features of patients with inborn errors of the IL-12/23-IFN-gamma circuit.

Abstract
INTRODUCTION Environmental non tuberculous mycobacteria and Bacillus Calmette-Guerin vaccines are weakly virulent mycobacteria. Nevertheless they may cause severe diseases in otherwise healthy children with no overt immunodeficiency. Parental consanguinity and familial forms are frequently observed among these patients, therefore this syndrome was named "Mendelian Susceptibility to Mycobacterial Disease". STATE OF THE ART In the last nine years, fife genes have been found to be mutated in patients with this syndrome: IFNGR1, IFNGR2, STAT1, IL12B, IL12RB1. Allelic heterogeneity accounts for ten distinct genetic disorders. Clinical phenotype differs between patients. The spectrum of disease extends from early-onset overwhelming mycobacterial infection to adult-onset localized disease and tuberculosis. Impaired IFN-gamma-mediated immunity is the common mechanism of the disease, outlining its major role in mycobacterial immunity. PERSPECTIVES AND CONCLUSIONS Better understanding of these disorders reveals an expanding clinical phenotype which justifies studying adult patients with pulmonary non tuberculous mycobacterial infection without known risk factors, severe BCGitis and recurrent tuberculosis. Molecular diagnosis makes it possible to introduce a specific regimen based on physiopathology.

Abstract
BACKGROUND Cutaneous nontuberculous mycobacterial infections result from external inoculation, spread of a deeper infection, or haematogenous spread of a disseminated infection. There are two species-specific infections (fish-tank or swimming-pool granuloma, due to Mycobacterium marinum, and Buruli ulcer, caused by M. ulcerans). Most infections, however, produce a nonspecific clinical picture. OBJECTIVES To define clinical patterns of cutaneous disease in nontuberculous mycobacterial infections. METHODS Fifty-one patients with cutaneous nontuberculous mycobacterial infections were reviewed. Clinical and histopathological features of normal hosts and immunosuppressed patients were compared. Two subgroups of immunosuppressed patients were distinguished: patients with cutaneous infection and patients with a disseminated infection and cutaneous involvement. RESULTS In immunosuppressed patients the number of lesions was significantly higher. Abscesses and ulceration were also more frequently observed. Different species were found in normal hosts and immunosuppressed patients. Several clinical patterns of cutaneous infection were defined: lymphocutaneous or sporotrichoid lesions; nonlymphocutaneous lesions at the site of trauma; folliculitis and furunculosis involving the lower extremities; disseminated lesions on the extremities in immunosuppressed patients. Two patterns were observed in patients with a disseminated infection: localized cutaneous lesions and disseminated cutaneous and mucosal lesions. CONCLUSIONS Cutaneous manifestations of nontuberculous mycobacterial infections may be classified according to criteria such as cutaneous lesions and immune status.

Abstract
IL-12, IL-23 and IFN-γ form a loop and have been thought to play a crucial role against infectious viruses, which are the prototype of “intracellular” pathogens. In the last 10 years, the generation of knock-out (KO) mice for genes that control IL-12/IL-23-dependent IFN-γ-dependent mediated immunity (STAT1, IFN-γR1, IFNγR2, IL-12p40 and IL-12Rβ1) and the identification of patients with spontaneous germline mutations in these genes has led to a re-examination of the role of these cytokines in anti-viral immunity. We here review viral infections in mice and humans with genetic defects in the IL-12/IL-23-IFN-γ axis. A comparison of the phenotypes observed in KO mice and deficient patients suggests that the human IL-12/IL-23-IFN-γ axis plays a redundant role in immunity to most viruses, whereas its mouse counterparts play a more important role against several viruses.

Abstract
Infection with Mycobacterium tuberculosis results in disease in 5-10% of exposed individuals, whereas the remainder controls infection effectively. Similar inter-individual differences in disease susceptibility are characteristic features of leprosy, typhoid fever, leishmaniasis and other chronic infectious diseases, including viral infections. Although the outcome of infection is influenced by many factors, it is clear that genetic host factors play an important role in controlling disease susceptibility to intracellular pathogens. Knowledge of the genes involved and their downstream cellular pathways will provide new insights for the design of improved and rationalized strategies to enhance host-resistance, e.g. by vaccination. In addition, this knowledge will aid in identifying better biomarkers of protection and disease, which are essential tools for the monitoring of vaccination and other intervention trials. The recent identification of patients with deleterious mutations in genes that encode major proteins in the type-1 cytokine (IL-12/IL23-IFN-gamma) axis, that suffered from severe infections due to otherwise poorly pathogenic mycobacteria (non-tuberculous mycobacteria (NTM) or M. bovis Bacille Calmette-Guerin (BCG)) or Salmonella species has revealed the major role of this system in innate and adaptive immunity to mycobacteria and salmonellae. Clinical tuberculosis has now been described in a number of patients with IL-12/IL23-IFN-gamma system defects. Moreover, unusual mycobacterial infections were reported in several patients with genetic defects in NEMO, a key regulatory molecule in the NFkappaB pathway. These new findings will be discussed since they provide further insights into the role of type-1 cytokines in immunity to mycobacteria, including M. tuberculosis.

Abstract
BACKGROUND Interferon gamma receptor 1 (IFNgammaR1) deficiency is a primary immunodeficiency with allelic dominant and recessive mutations characterised clinically by severe infections with mycobacteria. We aimed to compare the clinical features of recessive and dominant IFNgammaR1 deficiencies. METHODS We obtained data from a large cohort of patients worldwide. We assessed these people by medical histories, records, and genetic and immunological studies. Data were abstracted onto a standard form. FINDINGS We identified 22 patients with recessive complete IFNgammaR1 deficiency and 38 with dominant partial deficiency. BCG and environmental mycobacteria were the most frequent pathogens. In recessive patients, 17 (77%) had environmental mycobacterial disease and all nine BCG-vaccinated patients had BCG disease. In dominant patients, 30 (79%) had environmental mycobacterial disease and 11 (73%) of 15 BCG-vaccinated patients had BCG disease. Compared with dominant patients, those with recessive deficiency were younger at onset of first environmental mycobacterial disease (mean 3.1 years [SD 2.5] vs 13.4 years [14.3], p=0.001), had more mycobacterial disease episodes (19 vs 8 per 100 person-years of observation, p=0.0001), had more severe mycobacterial disease (mean number of organs infected by Mycobacterium avium complex 4.1 [SD 0.8] vs 2.0 [1.1], p=0.004), had shorter mean disease-free intervals (1.6 years [SD 1.4] vs 7.2 years [7.6], p<0.0001), and lower Kaplan-Meier survival probability (p<0.0001). M avium complex osteomyelitis was more frequent in dominant than in recessive patients (22/28 [79%] vs 1/8 [13%], p=0.002), and this disorder without other organ involvement arose only in dominant patients (9/28 [32%]). Disease caused by rapidly growing mycobacteria was present in more recessive than dominant patients (7/22 [32%] vs 1/38 [3%], p=0.002). INTERPRETATION Recessive complete and dominant partial IFNgammaR1 deficiencies have related clinical phenotypes, but are distinguishable by age at onset, dissemination, and clinical course of mycobacterial diseases. A strong correlation exists between IFNGR1 genotype, cellular responsiveness to interferon gamma, and clinical disease features.

Abstract
PURPOSE OF REVIEW Cytokines are soluble mediators involved in the development or function of the immune system. This paper reviews the literature on childhood-onset inherited disorders associated with impaired cytokine-mediated immunity. RECENT FINDINGS Cytokine-mediated immunity defects can be classified into seven different groups: defects in the interleukin (IL)-7 receptor (IL7RA), in the common cytokine receptor gamma chain (gammac) of the IL-2, -4, -7, -15, and -21, and in Jak3 (JAK3) downstream of the gamma chain; mutation in the IL-2 receptor alpha (IL-2RA) and defective expression of the IL-2Rbeta chain; mutations in the gene encoding for a chemokine receptor, CXCR4; mutations in five genes involved in the IL-12/23-interferon-gamma axis (IL12B, IL12RB1, IFNGR1, IFNGR2, STAT1); mutations in three genes involved in the nuclear factor-kappaB signaling pathway (IRAK4, NEMO, IkappaBA); mutations in the tumor necrosis factor receptor signaling pathway (TNFRSF1A); and mutations in the transforming growth factor-1 gene (TGFB1). SUMMARY Genetic cytokine-mediated immunity defects are associated with a highly heterogeneous group of clinical features, ranging from susceptibility to infections to developmental defects. This heterogeneity highlights the diversity and pleiotropy of cytokines. It is likely that many more cytokine defects and their responsive pathways will be discovered in the coming years, expanding further the heterogeneity associated with this group of childhood-onset illnesses.

Abstract
The ability to develop adequate immunity to intracellular bacterial pathogens is unequally distributed among human beings. In the case of tuberculosis, for example, infection with Mycobacterium tuberculosis results in disease in 5-10% of exposed individuals, whereas the remainder control infection effectively. Similar interindividual differences in disease susceptibility are characteristic features of leprosy, typhoid fever, leishmaniasis, and other chronic infectious diseases, including viral infections. The outcome of infection is influenced by many factors, such as nutritional status, co-infections, exposure to environmental microbes, and previous vaccinations. It is clear, however, that genetic host factors also play an important part in controlling disease susceptibility to intracellular pathogens. Recently, patients with severe infections due to otherwise poorly pathogenic mycobacteria (non-tuberculous mycobacteria or Mycobacterium bovis BCG) or Salmonella spp have been identified. Many of these patients were unable to produce or respond to interferon gamma, due to deleterious mutations in genes that encode major proteins in the type 1 cytokine (interleukin 12/interleukin 23/interferon gamma) axis (interleukin 12p40/interleukin 23p40, IL12 receptor beta1/IL23 receptor beta1, interferon gamma receptors 1 and 2, or signal transducer and activator of transcription 1). This axis is a major immunoregulatory system that bridges innate and adaptive immunity. Unusual mycobacterial infections were also reported in several patients with genetic defects in inhibitor of NFkappaB kinase gamma, a key regulatory molecule in the nuclear factor kappaB pathway. New findings discussed in this review provide further and sometimes surprising insights into the role of type 1 cytokines, and into the unexpected heterogeneity seen in these syndromes.

Abstract
Vertebral osteomyelitis caused by non-tuberculous mycobacteria is a rare disease, with only 31 cases and one nosocomial outbreak reported in the literature (MedLine review between 1965 and December 2003). The clinical features are often indistinguishable from those of pyogenic osteomyelitis. Early diagnosis of such infections is a major challenge because of the slow growth of these microorganisms. No consensus guidelines for the treatment of these infections exist. Prolonged anti-mycobacterial therapy in combination with surgical debridement is recommended.

Abstract
We identified two siblings homozygous for a single base pair deletion in the IFN-gammaR2 transmembrane domain (791delG) who presented with multifocal Mycobacterium abscessus osteomyelitis (patient 1) and disseminated CMV and Mycobacterium avium complex infection (patient 2), respectively. Although the patients showed no IFN-gammaR activity, their healthy heterozygous parents showed only partial IFN-gammaR activity. An HLA-identical bone marrow transplant from the mother led patient 1 to complete hemopoietic reconstitution, but only partial IFN-gammaR function. We cloned and expressed fluorescent fusion proteins of the wild-type IFN-gammaR2, an IFN-gammaR2 mutant previously described to produce a complete autosomal recessive deficiency (278del2), and of 791delG to determine whether the intermediate phenotype in the 791delG heterozygous state was caused by haploinsufficiency or a dominant negative effect. When cotransfected together with the wild-type vector into IFN-gammaR2-deficient fibroblasts, the fusion protein with 791delG inhibited IFN-gammaR function by 48.7 +/- 5%, whereas fusion proteins with 278del2 had no inhibitory effect. Confocal microscopy of 791delG fusion proteins showed aberrant diffuse intracellular accumulation without plasma membrane localization. The fusion protein created by 791delG did not complete Golgi processing, and was neither expressed on the plasma membrane, nor shed extracellularly. The mutant construct 791delG exerts dominant negative effects on IFN-gamma signaling without cell surface display, suggesting that it is acting on pathways other than those involved in cell surface recognition of ligand.

Abstract
Mycobacterium avium-intracellulare (MAI) rarely causes disease of the spine in healthy individuals. We describe an elderly woman who had isolated skeletal involvement with MAI, mimicking Pott's disease. She responded well to surgical excision of the inflamed tissue and antibiotic therapy. Osteomyelitis due to MAI must be differentiated from that due to Mycobacterium tuberculosis because the treatment regimens are different.

Abstract
Patients with defects in IFN-gamma- or IL-12-mediated immunity are susceptible to infections with Salmonella and non-tuberculous mycobacteria, but rarely suffer from infections with other intracellular pathogens such as Toxoplasma gondii. Here we describe macrophage and T cell function in eight individuals with partial IFN-gamma receptor 1 (IFN-gammaR1) deficiency due to a mutation that results in elevated cell surface expression of a truncated IFN-gammaR1 receptor that lacks the intracellular domain. We show that various effector mechanisms dependent on IFN-gammaR signaling are affected to different extents. Whereas TNF-alpha production was normally up-regulated in response to IFN-gamma, IL-12 production and CD64 up-regulation were strongly reduced, and IFN-gamma-mediated killing of the intracellular pathogens Salmonella typhimurium and T. gondii was completely abrogated in patient's macrophages. Since these patients suffer selectively from infections with non-tuberculous mycobacteria and Salmonella, but not T. gondii, despite sero-immunity in six of eight patients, which indicates previous contact with this pathogen, we next studied the role of TNF-alpha as a possible immune compensatory mechanism. IFN-gamma-induced killing of T. gondii appeared to be partially mediated by TNF-alpha, and addition of TNF-alpha could compensate for the abrogated killing of T. gondii in the patient's macrophages. In contrast, IFN-gamma-mediated killing of S. typhimurium appeared to be independent of TNF-alpha. We propose that the divergent role of TNF-alpha in IFN-gamma-induced killing of T. gondii and S. typhimurium may at least partially explain the highly selective susceptibility of patients.

Abstract
Host genetic factors are important in determining the outcome of infections caused by intracellular pathogens, including mycobacteria and salmonellae, but until now have been poorly characterized. Recently, some individuals with severe infections due to otherwise weakly pathogenic mycobacteria (non-tuberculous mycobacteria or Mycobacterium bovis bacille Calmette-Guérin) or Salmonella species have been shown to be unable to produce or respond to interferon-gamma. This inability results from mutations in any of five genes encoding essential proteins of the type 1 cytokine cascade: interleukin-12p40, interleukin-12R beta 1, interferon-gamma R1, interferon-gamma R2 or STAT1. Ten syndromes have thus far been identified. Recent insights in genetically controlled host defense and susceptibility to mycobacterial disease are discussed.

Abstract
Humans are exposed to a variety of environmental mycobacteria (EM), and most children are inoculated with live Bacille Calmette-Guérin (BCG) vaccine. In addition, most of the world's population is occasionally exposed to human-borne mycobacterial species, which are less abundant but more virulent. Although rarely pathogenic, mildly virulent mycobacteria, including BCG and most EM, may cause a variety of clinical diseases. Mycobacterium tuberculosis, M. leprae, and EM M. ulcerans are more virulent, causing tuberculosis, leprosy, and Buruli ulcer, respectively. Remarkably, only a minority of individuals develop clinical disease, even if infected with virulent mycobacteria. The interindividual variability of clinical outcome is thought to result in part from variability in the human genes that control host defense. In this well-defined microbiological and clinical context, the principles of mouse immunology and the methods of human genetics can be combined to facilitate the genetic dissection of immunity to mycobacteria. The natural infections are unique to the human model, not being found in any of the animal models of experimental infection. We review current genetic knowledge concerning the simple and complex inheritance of predisposition to mycobacterial diseases in humans. Rare patients with Mendelian disorders have been found to be vulnerable to BCG, a few EM, and M. tuberculosis. Most cases of presumed Mendelian susceptibility to these and other mycobacterial species remain unexplained. In the general population leprosy and tuberculosis have been shown to be associated with certain human genetic polymorphisms and linked to certain chromosomal regions. The causal vulnerability genes themselves have yet to be identified and their pathogenic alleles immunologically validated. The studies carried out to date have been fruitful, initiating the genetic dissection of protective immunity against a variety of mycobacterial species in natural conditions of infection. The human model has potential uses beyond the study of mycobacterial infections and may well become a model of choice for the investigation of immunity to infectious agents.

Abstract
Patients with genetic lesions in the Type-1 cytokine/cytokine receptor pathway exhibit a selective susceptibility to severe infections with poorly pathogenic mycobacteria and non-typhi salmonella spp. These experiments of nature demonstrate that IL-12-dependent IFNgamma production is critical for granuloma formation and therefore host immunity against such pathogens. The essential role of granuloma formation for protective immunity to these organisms is emphasized by the differing granuloma forming capabilities and resultant clinical sequelae observed in these patients which seems to reflect their ability to produce or respond to IFNgamma (Fig. 9). At one pole of this spectrum, represented by the complete IFNgammaR1/2 deficient patients, there is a complete absence of mature granuloma formation, whereas with the less severe mutations (i.e. partial IFNgammaR1/2, complete IL-12p40 and complete IL-12Rbeta1 deficiency), granuloma formation is very heterogenous with wide variations in composition being observed. This suggests that in the latter individuals, who produce partial but suboptimal IFNgamma responses, other influences, including pathogen virulence and host genotype may also affect the type and scale of the cellular response elicited.
