Profile of 208 patients with inborn errors of immunity at a tertiary care center in South India

Primary immune deficiencies or inborn errors of immunity (IEI) are a heterogeneous group of disorders that predispose affected individuals to infections, allergy, autoimmunity, autoinflammation and malignancies. IEIs are increasingly being recognized in the Indian subcontinent. Two hundred and eight patients diagnosed with an IEI during February 2017 to November 2021 at a tertiary care center in South India were included in the study. The clinical features, laboratory findings including microbiologic and genetic data, and treatment and outcome details were analyzed. The diagnosis of IEI was confirmed in a total of 208 patients (198 kindreds) based on relevant immunological tests and/or genetic tests. The male-to-female ratio was 1.8:1. Of the 208 patients, 72 (34.6%) were < 1 yr, 112 (53.8%) were 1-18 years, and 24 (11.5%) were above 18 years. The most common IEI in our cohort was SCID (17.7%) followed by CGD (12.9%) and CVID (9.1%). We also had a significant proportion of patients with DOCK8 deficiency (7.2%), LAD (6.2%) and six patients (2.8%) with autoinflammatory diseases. Autoimmunity was noted in forty-six (22%) patients. Molecular testing was performed in 152 patients by exome sequencing on the NGS platform, and a genetic variant was reported in 132 cases. Twenty-nine children underwent 34 HSCT, and 135 patients remain on supportive therapy such as immunoglobulin replacement and/or antimicrobial prophylaxis. Fifty-nine (28.3%) patients died during the study period, and infections were the predominant cause of mortality. Seven families underwent prenatal testing in the subsequent pregnancy. We describe the profile of 208 patients with IEI, and to the best of our knowledge, this represents the largest data on IEI from the Indian subcontinent reported so far.

Indian Academy of Pediatrics Position Paper on Nurturing Care for Early Childhood Development

Early childhood development (ECD) refers to the physical, motor, socio-emotional, cognitive, and linguistic development of a young child. The 'Countdown to 2030' global distribution of 'children at risk of poor development' indicates the need for urgent action and investment in ECD. Nurturing care enhances ECD, even in the presence of adversities. Strategic actions should exist at multiple levels: the family, community, health care providers and government. Previously, child health related policies and programs of the Government of India functioned in isolation, but have recently started demonstrating multi-sectoral collaboration. Nonetheless, the status of ECD in India is far from optimal. There is strong evidence that parenting programs improve outcomes related to ECD. This is dependent on key programmatic areas (timing, duration, frequency, intensity, modality, content, etc.), in addition to political will, funding, partnership, and plans for scaling up. Each country must implement its unique ECD program that is need-based and customized to their stakeholder community. Barriers like inadequate sensitization of the community and low competency of health care providers need to be overcome. IAP firmly believes that responsive parenting interventions revolving around nurturing care should be incorporated in office practice. This paper outlines IAP's position on ECD, and its recommendations for pediatricians and policy makers. It also presents the roadmap in partnership with other stakeholders in maternal, neonatal, and child health; Federation of Obstetric and Gynaecological Societies of India (FOGSI), National Neonatology Forum (NNF), World Health Organization (WHO), and United Nation Children Fund (UNICEF).

Clinical and Molecular Findings in Mendelian Susceptibility to Mycobacterial Diseases: Experience From India

Mendelian Susceptibility to Mycobacterial diseases (MSMD) are a group of innate immune defects with more than 17 genes and 32 clinical phenotypes identified. Defects in the IFN-γ mediated immunity lead to an increased susceptibility to intracellular pathogens like mycobacteria including attenuated Mycobacterium bovis-Bacillus Calmette-Guérin (BCG) vaccine strains and non-tuberculous environmental mycobacteria (NTM), Salmonella, fungi, parasites like Leishmania and some viruses, in otherwise healthy individuals. Mutations in the IL12RB1 gene are the commonest genetic defects identified. This retrospective study reports the clinical, immunological, and molecular characteristics of a cohort of 55 MSMD patients from 10 centers across India. Mycobacterial infection was confirmed by GeneXpert, Histopathology, and acid fast bacilli staining. Immunological workup included lymphocyte subset analysis, Nitro blue tetrazolium (NBT) test, immunoglobulin levels, and flow-cytometric evaluation of the IFN-γ mediated immunity. Genetic analysis was done by next generation sequencing (NGS). Disseminated BCG-osis was the commonest presenting manifestation (82%) with a median age of presentation of 6 months due to the practice of BCG vaccination at birth. This was followed by infection with Salmonella and non-typhi Salmonella (13%), Cytomegalovirus (CMV) (11%), Candida (7%), NTM (4%), and Histoplasma (2%). Thirty-six percent of patients in cohort were infected by more than one organism. This study is the largest cohort of MSMD patients reported from India to the best of our knowledge and we highlight the importance of work up for IL-12/IL-23/ISG15/IFN-γ circuit in all patients with BCG-osis and suspected MSMD irrespective of age.

Consensus Statement of the Indian Academy of Pediatrics on Evaluation and Management of Attention Deficit Hyperactivity Disorder

JUSTIFICATION

Attention-Deficit/Hyperactivity Disorder (ADHD) is highly prevalent in children worldwide. Management of ADHD requires a systematic, multidisciplinary approach and therefore evidence-based, standardized national guidelines are essential.

PROCESS

A meeting for formulation of national consensus guidelines on neurodevelopmental disorders was organized by Indian Academy of Pediatrics in Mumbai, on 18th and 19th December, 2015. The invited experts included Pediatricians, Developmental Pediatricians, Pediatric Neurologists, Psychiatrists, Remedial Educators and Clinical Psychologists. The participants framed guidelines after extensive discussions.

OBJECTIVE

To provide consensus guidelines on evaluation and management of ADHD in children in India.

RECOMMENDATIONS

ADHD is a chronic condition and thus education of patients, families, and teachers regarding the diagnosis is an integral part of management. Involvement of patient the and the family in the management program is extremely vital. Management of ADHD centers on the achievement of target outcomes, which are chosen in collaboration with the child, parents, and school personnel. Coexisting conditions must be treated concurrently with ADHD. Modalities of management of ADHD include behavioral interventions, medications, and educational interventions. These modalities can be implemented individually or in combination.

Phase I safety & preliminary acceptability of nonoxynol-9 vaginal pessary as a vaginal microbicide in low risk women in Pune, India

BACKGROUND & OBJECTIVES

Though nonoxynol-9 (N-9) is available in India as a spermicidal pessary, data on its safety as a potential microbicide among Indian women are not available. Nonoxynol-9 containing compounds have shown anti-HIV activity in in vitro studies and protection against cervical infections. Nonoxynol-9 is being extensively evaluated as a vaginal microbicide world-wide. We assessed the safety and preliminary acceptability of nonoxynol-9 pessary as a vaginal microbicide in women at low risk for human immunodeficiency virus (HIV) infection and sexually transmitted diseases (STDs).

METHODS

Twenty three HIV seronegative women enrolled in the study were given Today pessarys containing 5 per cent of nonoxynol-9 for vaginal use at bedtime for 14 days. Colposcopy was done at enrollment and on day 14 and speculum examination on day 7 to assess the local toxicity.

RESULTS

Most of the women (16/23, 69.6%) did not experience any symptoms of genital irritation. The remaining 7 (30.4%, 95% CI 11.6-49.2) women reported 11 episodes of mild irritative symptoms of short duration. On clinical examination, three adverse events were reported of which one could have been product related. Eight (34.8%) women showed willingness to use the product for protection against HIV transmission if it was approved.

INTERPRETATION & CONCLUSION

Nonoxynol-9 vaginal pessary was found to be safe and acceptable in once daily dose in low risk women after consecutive use for 14 days. Willingness for future use, if found safe and effective for HIV prevention was shown by 8 (34.8%) women.

Aetiology and clinical features of acute childhood diarrhoea in an outpatient clinic in Vellore, India

The aetiology of acute diarrhoea was investigated in 245 children less than 3 years old in a paediatric outpatient clinic in southern India. In 55% of the children organisms were found in the stools, and one quarter were infected with multiple organisms. Viruses, enteropathogenic E. coli, shigella and campylobacter species accounted for 75% of all isolates. Cholera and helminthiasis were rare, and no child had amoebiasis. Clinical findings were useful in the diagnosis of shigella and rotavirus infection only. Children with shigellosis had classical dysentery, and a greater number of stools; they were unlikely to be breast-fed, to be less than 6 months old, or to have watery stools. Rotavirus infections were characterized by vomiting. Only 20% of the 245 children had an infection which could be treated effectively with antimicrobials.
