Petley E, Yule A, Alexander S, Ojha S, Whitehouse WP. The natural history of ataxia-telangiectasia (A-T): A systematic review. PLoS One 2022; 17:e0264177. [PMID: 35290391 PMCID: PMC9049793 DOI: 10.1371/journal.pone.0264177] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Accepted: 02/06/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Ataxia-telangiectasia is an autosomal recessive, multi-system, and life-shortening disease caused by mutations in the ataxia-telangiectasia mutated gene. Although widely reported, there are no studies that give a comprehensive picture of this intriguing condition. OBJECTIVES Understand the natural history of ataxia-telangiectasia (A-T), as reported in scientific literature. SEARCH METHODS 107 search terms were identified and divided into 17 searches. Each search was performed in PubMed, Ovid SP (MEDLINE) 1946-present, OVID EMBASE 1980 -present, Web of Science core collection, Elsevier Scopus, and Cochrane Library. SELECTION CRITERIA All human studies that report any aspect of A-T. DATA COLLECTION AND ANALYSIS Search results were de-duplicated, data extracted (including author, publication year, country of origin, study design, population, participant characteristics, and clinical features). Quality of case-control and cohort studies was assessed by the Newcastle-Ottawa tool. Findings are reported descriptively and where possible data collated to report median (interquartile range, range) of outcomes of interest. MAIN RESULTS 1314 cases reported 2134 presenting symptoms. The most common presenting symptom was abnormal gait (1160 cases; 188 studies) followed by recurrent infections in classical ataxia-telangiectasia and movement disorders in variant ataxia-telangiectasia. 687 cases reported 752 causes of death among which malignancy was the most frequently reported cause. Median (IQR, range) age of death (n = 294) was 14 years 0 months (10 years 0 months to 23 years 3 months, 1 year 3 months to 76 years 0 months). CONCLUSIONS This review demonstrates the multi-system involvement in A-T, confirms that neurological symptoms are the most frequent presenting features in classical A-T but variants have diverse manifestations. We found that most individuals with A-T have life limited to teenage or early adulthood. Predominance of case reports, and case series demonstrate the lack of robust evidence to determine the natural history of A-T. We recommend population-based studies to fill this evidence gap.

Abstract
OBJECTIVES To study the incidence, clinical manifestations, and genetic spectrum of primary immunodeficiency diseases (PID)/inborn errors of immunity (IEI) in a tertiary care hospital in Southern India. METHODS A retrospective analysis of all patients with a clinical suspicion of PID/IEI seen at a tertiary care hospital was performed. All patients had at least one or more warning signs of PID. Serum immunoglobulin levels and other targeted investigations were performed as warranted by the clinical presentation. All families with suspected PID were counseled and offered genetic testing. RESULTS A total of 225 children were evaluated for PID during the study period of 6 y. Fifty-six of them did not meet the European Society of Immunodeficiencies (ESID) criteria (working definition of clinical diagnosis) and were excluded. An IEI was found in 30/49 (61.2%) patients. The most frequent reason for referral was recurrent/unusual or serious infections (28%), or cytopenia (16%). Group IV diseases of immune dysregulation was the most common category (19%), followed by group III predominant antibody deficiencies in 23/163 (14%), as per the International Union of Immunological Societies (IUIS) classification. CONCLUSIONS This study highlights the heterogeneity of the present cohort, the underuse of genetic tests, and efforts to provide optimal care for children with possible IEI in this center.

Spectrum of Inborn errors of immunity in a cohort of 90 patients presenting with complications to BCG vaccination in India. Scand J Immunol 2021; 93:e13010.

Abstract
World Health Organisation recommends the practice of BCG vaccination at birth in countries which have a high incidence of tuberculosis and/or high leprosy burden. The BCG vaccination is considered safe for a competent immune system. However, in children with weakened immune systems cause of which can be primary or secondary, the vaccine may lead to side effects which can be localized or disseminated. In this study, we report a spectrum of inborn errors of immunity (IEI) commonly referred to as primary immunodeficiency disorders (PIDs) diagnosed in a large cohort of patients presenting with complications to BCG vaccination from India. Retrospective data analysis of patients referred to ICMR- National Institute of Immunohematology (ICMR-NIIH) for IEI workup between 2007 and 2019 was done. IEI was identified in n = 52/90 (57.7%) patients presenting with BCG complications. Of these, n = 13(14.4%) patients were diagnosed with severe combined immune deficiency, n = 15(16.7%) with chronic granulomatous disease, n = 19(21.1%) with Inborn errors of IFN-γ immunity, n = 4(4.4%) with Combined immunodeficiency and n = 1(1.1%) with Leucocyte Adhesion Deficiency type1. Majority of cases with BCGosis (88%) had an underlying IEI. This study strongly highlights the need for evaluation of patients with BCG complications for underlying IEI. While disseminated BCGosis strongly predicts underlying IEI, even localized persistent adenitis may be a warning sign of underlying IEI. It is also strongly recommended to record a family history of previous sibling death prior to administration of this live vaccine and deferring live vaccine till the diagnosis of IEI is ruled out in cases with a positive family history.

Abstract
Isoniazid (INH) is a first-line tuberculosis (TB) drug and is currently recommended as part of active and latent TB treatment in all ages. INH adverse reactions range from mild hepatitis to severe neurological symptoms and psychosis. Since its introduction in the 1950s, many case reports have explored INH-induced psychosis. We describe a 12-year-old girl with acute onset hallucinations and delusions as a rare complication of INH and review previous case reports and identified risk factors. Pediatricians need to be aware of this less common side effect as they work through a differential of acute psychosis in children.

Abstract
INTRODUCTION The prevalence of undiagnosed primary immunodeficiency diseases is remarkably high and contributes to increasing the rate of morbidity and mortality among this group of patients. OBJECTIVE To examine the 10 warning sign scoring system in patients suspected of primary immune deficiency and also estimate the diagnostic delay in patients with proven disease. METHODS This descriptive cross-sectional study was carried out during the years 2015-2016 in Ali Asghar (AS) Clinic and Hospital. Two hundred patients with suspected primary immune deficiency disease were eligible for inclusion in the study. Multivariable logistic regression analysis was used to determine the relation between findings. RESULTS In this study, the majority of suspected cases of immunodeficiency were males (57%) with a mean age of 3.33±2.89 years. Twenty-one (10.5%) patients were diagnosed with immunodeficiency disease. The mean diagnostic delay among primary immune deficient patients was 2.05±1.7 years. There was a significant relationship between having parental consanguinity (OR=2.68, 95% CI: 1.07-6.70), allergies (OR=5.03, 95% CI: 1.13-22.31), vaccine adverse effects (OR=9.31, 95% CI: 1.24-69.96) and primary immune deficiency diagnosis. No association was observed between age (OR=0.98, 95% CI: 0.84-1.14), gender (OR=0.99, 95% CI: 0.39-2.47), immune deficiency scoring (OR=0.68, 95% CI: 0.31-1.45) and primary immune deficiency diagnosis. CONCLUSION Ten warning sign scoring system is of less value to consider a patient suspected of having primary immune deficiency. There is a meaningful delay in diagnosis of primary immune deficiencies especially in antibody deficiency defects which seeks further upgrading of knowledge in physicians.

Abstract
Background Primary Immunodeficiency Disorders (PIDs) are well-known disorders in the West. but the recognition and diagnosis of these disorders is challenging in developing countries. We present the spectrum of PIDs seen at a tertiary care center in Pakistan, identified using clinical case definitions and molecular methods. Methods A retrospective chart review of children suspected to have PID was conducted at the Aga Khan University Hospital (AKUH) Karachi, Pakistan from 2010 to 2016. Data on demographics, clinical features, family history of consanguinity, sibling death, details of laboratory workup done for PID and molecular tests targeted panel next generation sequencing (NGS) or whole exome sequencing (WES) performed at the Geha laboratory at Boston Children’s Hospital, USA was collected. The study was exempted from the Ethical Review Committee of AKUH. Results A total of 43 children visited the hospital with suspected PID during the study period. Genetic testing was performed in 31/43 (72.1%) children. A confirmed diagnosis of PID was established in 20/43 (46.5%) children. A pathogenic gene variant was identified in 17(85%) of the 20 confirmed cases (Table 1). Twelve (60%) of the confirmed cases of PID were male. The most common presenting symptom was recurrent diarrhea 11/20 (55%). The mean (±S.D) age of the cases at the time of diagnosis was 4.2 (±4.1) years. Chronic granulomatous disease (CGD) was the most common 6/20 (30%) disorder, followed by severe combined immunodeficiency (SCID) 3/20 (15%), leukocyte adhesion deficiency (LAD) 3/20 (15%), agammaglobulinemia/hypogammaglobulinemia 3/20 (15%), and Hermansky-Pudlak Syndrome (HPS) 2/20 (10%). Wiskott-Aldrich Syndrome, Immunodeficiency Centromeric Instability and Facial Anomalies Syndrome (ICF 2), Trichohepatoenteric syndrome (TRES), and C3 deficiency were each diagnosed once {1/20 (4.3%) each} (Table 1). Of these 20 confirmed cases, almost all 19/20 (95%) had a family history of consanguinity. Sibling death was reported in 5/20 (25%) of these cases. Five out of the 20 (25%) children died over the 7-year period for various reasons. Conclusion PIDs are not uncommon in Pakistan; their diagnosis may be missed or delayed due to the overlapping of clinical features of PID with other diseases and a lack of diagnostic facilities. There is a need to build capacity for early recognition and diagnosis of PIDs to decrease morbidity and mortality.

Abstract
A primary immune deficiency disorder is often suspected in children with recurrent deep seated and fungal infections and those admitted to pediatric intensive care units. Chronic granulomatous disease (CGD) is inherited disorder leading to infections caused due to defective superoxide production. Cases referred for testing for a primary immunodeficiency disorder were tested for Dihydrorhodamine 123 (DHR) assay by flow cytometry and nitroblue tetrazolium dye (NBT) slide test. The unstimulated and stimulated samples were tested for oxidative burst activity which gives bright fluorescence due to formation of Rhodamine 123 on flow cytometry and blue formazan pigment in NBT slide test. The test results were reported in real time. From a total of 330 patients screened for chronic granulomatous disease using DHR and NBT slide test, 17 patients (5.1%) were found to have CGD. These included 12 boys and 5 girls. They presented with deep seated infections, recurrent and multiple abscess, recurrent pneumonia and granulomatous lymphadenitis. The causative organisms were Mycobacteriae, Staphylococcus, Burkholderia cepacia, Pseudomonas, Aspergillus and Cytomegalovirus. In 6 out of 17 positive cases family studies were carried out. On follow up five children succumbed to disease, two patients underwent allogeneic bone marrow transplant, the chimerism status was demonstrated by repeat DHR assay at day 50 post-transplant. Rest are in follow up under prophylactic antibiotics and supportive care. As facilities for molecular testing are not easily available for primary immuno deficiency disorders, flow cytometry based clinical laboratories can help to screen for some of the frequently suspected disorders like chronic granulomatous disease. This has aided in paediatric care in our centre.

Abstract
The pathogenesis of tuberculosis (TB) remains poorly understood, as no more than 5-10% of individuals infected with Mycobacterium tuberculosis go on developing clinical disease. The contribution of human genetics to TB pathogenesis has been amply documented by means of classic genetics since the turn of the twentieth century. Over the last 20 years, following-up on the study of Mendelian susceptibility to mycobacterial disease (MSMD), monogenic disorders have been found to underlie TB in some patients. Rare inborn errors of immunity, such as autosomal recessive, complete IL-12Rβ1 and TYK2 deficiencies, impairing the IL-12- and IL-23-dependent induction of IFN-γ, were initially identified in a few patients. More recently, homozygosity for a common variant of TYK2 (P1104A) that selectively disrupts cellular responses to IL-23 was found in two cohorts of TB patients. It shows high penetrance in areas endemic for TB and appears to be responsible for about 1% of TB cases in populations of European descent. Both rare and common genetic etiologies of TB affect IFN-γ immunity, providing a rationale for novel preventive and therapeutic approaches for TB control, including the use of recombinant IFN-γ.

Primary Immunodeficiency Diseases and Bacillus Calmette-Guérin (BCG)-Vaccine-Derived Complications: A Systematic Review. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2020; 8:1371-1386. [PMID: 32006723 DOI: 10.1016/j.jaip.2020.01.038] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 01/13/2020] [Accepted: 01/14/2020] [Indexed: 02/08/2023]
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
OBJECTIVES To report the distribution pattern of various categories of primary immunodeficiency disorders (PIDs) in children from North India, frequency of warning signs and critical parameters for evaluation. METHODS In this retrospective study, 528 children below 18 y of age after clinical assessment and presentation suggestive of PID were further screened by immunophenotyping for immune cell markers by flow cytometry. RESULTS A total of 120 (23%) children were diagnosed with PID with median age at diagnosis being 2.5 y in males and 3.5 y in females and an average delay in diagnosis from onset of symptoms being approximately 5 y. Chronic lower respiratory tract infections, gastrointestinal symptoms like persistent diarrhea and failure to thrive were amongst the most common warning signs in these patients. PIDs were classified according to the International Union of Immunological Societies' (IUIS) criteria. The diagnosis of index study subjects included combined humoral and cellular immunodeficiency (29%), phagocytic defects (29%), followed by predominantly antibody deficiency (18%), innate immunity and dysregulation (17%) and other well-defined syndromes (7%). A family history of PID (23%), consanguineous marriage (8%) and previous sibling death (23%) were observed as major clinical predictors/clues for underlying PID. All children received prophylactic antibiotics and/or antifungals in addition to specific therapy for underlying immune deficiency. CONCLUSIONS The field of PIDs in India remains largely unexplored and we are faced with various challenges in the diagnosis of PIDs due to lack of awareness as well as absence of equipped immunological laboratory support. The authors propose a methodical step-wise laboratory diagnostic approach that can facilitate early diagnosis and timely intervention of these mis/underdiagnosed disorders.

Abstract
BACKGROUND Chronic granulomatous disease (CGD) is an X-linked (XL) or autosomal recessive (AR) primary immunodeficiency disease. Respiratory burst assessment by flow cytometry is a rapid test of granulocyte stimulation, and results predict the underlying genotype. This study aims to describe the immune-phenotypic profile of patients with CGD diagnosed in our center and correlate that with underlying genetic mutations. METHODS Immuno-phenotypic and genetic data on all patients with CGD diagnosed at Sultan Qaboos University Hospital (SQUH) were reviewed. RESULTS A total of 32 patients were diagnosed with CGD using molecular studies. Genetically confirmed individuals included 1 patient with XL-CGD (a large deletion involving the CYBB and XK genes resulting in a McLeod phenotype), 27 patients with AR-CGD with a c.579G>A (p.Trp193X) mutation at the NCF1 gene, and 4 patients with AR-CGD with a c.784G>A (p.Gly262Ser) mutation at the NCF1 gene. Flow cytometry and molecular results were available for comparison in 26 patients with AR-CGD. The patients with AR-CGD had a range of flow cytometry-generated fluorescent patterns as follows: reduced neutrophil stimulation with a sharp peak (12/26), reduced neutrophil stimulation with a broad peak (11/26), and a complete lack of neutrophil stimulation (3/26). No consistent flow cytometry-generated fluorescent pattern was observed in either of the 2 AR mutations identified in our patients. CONCLUSION Flow cytometry is a robust test of CGD diagnosis. However, results should be interpreted with caution when predicting the underlying probable genotype, and results need to be complemented with definitive molecular studies.

Serial Serum Immunoglobulin G (IgG) Trough Levels in Patients with X-linked Agammaglobulinemia on Replacement Therapy with Intravenous Immunoglobulin: Its Correlation with Infections in Indian Children. J Clin Immunol 2017; 37:311-318.

Abstract
Patients with primary antibody deficiency (PAD) are being increasingly diagnosed in the developing world. However, care of these children continues to remain suboptimal due to financial and social constraints. Immunoglobulin (Ig) trough level is an important predicting factor for infections in children on replacement immunoglobulin therapy. There are no data on this aspect from the developing world. Therefore, we studied serial immunoglobulin G (IgG) trough levels in 14 children with X-linked agammaglobulinemia (XLA) receiving replacement intravenous immunoglobulin (IVIG). Infections during the course of enrolment were documented prospectively. Mean age at the time of diagnosis was 5.1 years (range 2-11 years). Mean time from onset of symptoms and initiation of therapy was 3.3 years. Two children had established chronic lung disease prior to enrolment. Total numbers of major and minor infections were 7 and 40, respectively. At a mean dose of 414 mg/kg/month of IVIG, mean trough IgG level was 435 mg/dl. Median IgG trough levels during the episodes of major and minor infections were 244 and 335 mg/dl, respectively. An escalation in IVIG dose of 100 mg/kg produced an increase in serum IgG levels by 53.6 mg/dl. Median trough IgG level of 354 mg/dl was found to be protective with 64% sensitivity and 75% specificity. A median dose of 397 mg/kg was required to keep children free of infections. Despite financial constraints and several challenges in the context of a developing country, children with XLA have good outcome on replacement immunoglobulin therapy. Furthermore, mean biological trough IgG levels are much lower than reported in for Western patients; however, studies involving larger number of subjects are required in future to draw firm conclusions.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (M.tb) and a few related mycobacteria, is a devastating disease, killing more than a million individuals per year worldwide. However, its pathogenesis remains largely elusive, as only a small proportion of infected individuals develop clinical disease either during primary infection or during reactivation from latency or secondary infection. Subacute, hematogenous, and extrapulmonary disease tends to be more frequent in infants, children, and teenagers than in adults. Life-threatening primary TB of childhood can result from known acquired or inherited immunodeficiencies, although the vast majority of cases remain unexplained. We review here the conditions conferring a predisposition to childhood clinical diseases caused by mycobacteria, including not only M.tb but also weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria. Infections with weakly virulent mycobacteria are much rarer than TB, but the inherited and acquired immunodeficiencies underlying these infections are much better known. Their study has also provided genetic and immunological insights into childhood TB, as illustrated by the discovery of single-gene inborn errors of IFN-γ immunity underlying severe cases of TB. Novel findings are expected from ongoing and future human genetic studies of childhood TB in countries that combine a high proportion of consanguineous marriages, a high incidence of TB, and an excellent clinical care, such as Iran, Morocco, and Turkey.

Abstract
Primary immunodeficiency disorders (PID) are under-reported from the developing world. We present data regarding diagnosis and outcome from a hospital-based registry in India. Forty-seven patients fulfilled diagnostic criteria. Majority were males. Subgroups were disorders of immune dysregulation-29%, B&T-cell abnormalities-28%, predominant antibody deficiencies-23%, other well-defined immunodeficiencies-15%, and phagocyte disorders-4%. Molecular diagnosis was attempted in 12 and was positive in seven. Overall 24 children died. Only three out of 28 children needing stem cell transplant (SCT) underwent the same. Registry data highlights that molecular diagnosis and SCT are a rarity for children with PIDs in the developing world and mortality is high.

Abstract
The authors report a series of seven cases of X-linked Agammaglobulinemia, diagnosed and receiving treatment at a tertiary care centre in Mumbai. The ages of the patients ranged from 15 mo to 15 y. After diagnosis at a mean age of 3 ½ y, all were advised intravenous immunoglobulin (IvIg) infusion therapy in doses of 400-600 mg/kg every 3-4 wk. They were followed up for an average duration of 9 y, throughout which the complications and overall response to immunoglobulin therapy have been observed. The clinical profiles of each of these cases were retrospectively analysed with respect to age at diagnosis, frequency and severity of infections before and after initiation of treatment, co-morbidities and response to therapy. The results demonstrate the importance of early diagnosis and its correlation with decreased complications.

Abstract
Chronic granulomatous disease (CGD) results from an inherited defect in the phagocytic cells of the immune system. It is a genetically heterogenous disease caused by defects in one of the five major subunits of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. There is a paucity of data from India on CGD. We herein describe the clinical features in 17 children with CGD from a single tertiary referral center in India. A detailed analysis of the clinical features, laboratory investigations and outcome of 17 children 7 with X-linked (XL) and 10 with autosomal recessive (AR) form was performed. Diagnosis of CGD was based on an abnormal granulocyte oxidative burst evaluated by either Nitroblue Tetrazolium (NBT) test or flow cytometry based Dihyrorhodamine 123 assay or both. The molecular diagnosis was confirmed by genetic mutation analysis in 13 cases. The mean age at diagnosis and the age at onset of symptoms was significantly lower in children diagnosed with XL- CGD compared those with AR disease. Mutations were detected in CYBB gene in 6 patients with XL-CGD and NCF-1 gene mutations were observed in 7 cases of AR- CGD. The course and outcome of the disease was much worse in children diagnosed with X-linked form of disease compared to AR forms of the disease; 4/7 (57%) children with X-CGD were dead at the time of data analysis. This is one of the largest series on chronic granulomatous disease from any developing country.

Abstract
Primary immunodeficiencies (PIDs) are genetic disorders of the immune system comprising many different phenotypes. Although previously considered rare, recent advances in their clinical, epidemiological, and molecular definitions are revealing how much we still need to learn about them. For example, geographical and ethnic variations as well as the impact of certain practices influence their frequency and presentation, making it necessary to consider their study in terms of regions. The Latin American Society for Immunodeficiencies was established as an organization dedicated to provide scientific support for basic and clinical research and to develop tools and educational resources to promote awareness in the medical community. Initiatives such as these are positively influencing the way PIDs are tackled in these countries, as shown by recent reports and publications. This paper provides a historical compilation and a current view of the many issues faced by scientists studying these diseases in these countries, highlighting the diverse scientific contributions and offering a promising perspective for the further developments in this field in Latin America.
