Utility of RNTCP (NTEP) guidelines in microbiological confirmation of pediatric tuberculosis.

OBJECTIVE: To estimate the proportion of microbiologically confirmed disease among children diagnosed with tuberculosis using RNTCP guidelines. MATERIALS AND METHODS: Retrospective chart review of a cohort of 151 children (aged between 1 month and 18 years) diagnosed with Tuberculosis between December 2016 and June 2020 at a pediatric department of a tertiary care hospital. We collected information on AFB (Acid Fast Bacillus) smear and Cartridge Based Nucleic Acid Amplification Test (CB NAAT) results. RESULTS: Out of 151 children with a diagnosis of Tuberculosis, 66 (44%) children were found to have microbiologically confirmed disease. Confirmatory rate was almost equal in children less than <5 and >5 years (48% vs 52%). Confirmatory rate did not differ between pulmonary and extra pulmonary samples (49% and 53%). Cartridge Based Nucleic Acid Amplification Test outperformed AFB by 10%, which was statistically significant (p = .000 by fisher exact test). CONCLUSION: Although considered paucibacillary in nature, microbiological confirmation can be obtained in almost up to half of children with a diagnosis of TB by using RNTCP guidelines. Neither young age nor type of TB is a deterrent to bacteriologically confirm TB in children.

Clinical and immunological profile of children with Mendelian Susceptibility to Mycobacterial Diseases (MSMD) from an Indian tertiary care hospital.

Inherited disorders of interferon gamma (IFN) γ, also known as Mendelian Susceptibility to Mycobacterial Diseases (MSMD), have been classified as Primary Immuno Deficiency 6, ie, defect in intrinsic and innate immunity. As IFN-γ plays an important role in conferring immunity to mycobacterial infections, its disorders have been increasingly reported in association with disseminated BCG/Non Tubercular Mycobacterial infections. So far germline mutations in 16 genes have been reported, most common being IL12RB1 followed by IFNGR1 and IFNGR2. There is limited published data on MSMD from India and here we report 4 unrelated children with proven mutations in IL12RB1 in 2 children and IFNGR1 and IFNGR2 in one each with disseminated opportunistic mycobacterial infections from a tertiary care centre in India.

Revised Antituberculosis Drug Doses and Hepatotoxicity in HIV Negative Children.

OBJECTIVES: To compare the incidence of anti tuberculosis drug-induced hepatotoxicity (ATDH) with those on old vs. revised WHO doses in human immunodeficiency virus (HIV) negative children. The secondary objective was to determine the overall incidence of hepatitis in children on Anti tubercular treatment (ATT) and isoniazid prophylactic therapy (IPT). METHODS: Children attending pediatric outpatient / admitted in wards, on ATT/ IPT between January 2007 and December 2017 (11 y) were included. Children were divided into Group 1 (treated based on old doses, from January 2007 to December 2011) and Group 2 (treated based on revised doses from January 2012 to December 2017). Children with multi drug resistant tuberculosis (MDRTB) and pre-existing liver disease were excluded. RESULTS: A total of 515 children were enrolled. Twelve children developed ATDH with an overall incidence of 2.3%. Five out of 260 (1.9%) developed hepatitis with old doses vs. 7 of the 255 (2.7%) with revised doses; this difference was not statistically significant. When calculated only for active TB (excluding children on IPT), overall incidence of hepatitis was 2.7%. Comparison between group 1 (2.04%) and group 2 (3.5%) was again not statistically significant. Ten out of 12 children who developed hepatitis were restarted on ATT without recurrence. No child on IPT developed hepatitis. There was no mortality. CONCLUSIONS: Revised WHO dosing does not increase incidence of hepatitis compared to old dosing in HIV negative children. Overall incidence was 2.3%. Hepatitis did not occur with IPT.

Clinical profile and outcome of clinical BCG disease in infants.

OBJECTIVE: To describe the clinical profile, immunological status and outcome of BCG disease in infants. METHODS: All infants with a diagnosis of BCG disease in a period of 17 months were followed up. RESULTS: Among 25 infants with BCG disease; 19 had local/regional involvement and 6 had suspected or confirmed distant/disseminated disease, Mean (range) age of presentation was 3.6 (1.5-9) months. Two of 6 infants with disseminated disease required second-line anti-tubercular treatment. One infant with confirmed disseminated disease had INFg R1 receptor deficiency. There was no mortality. CONCLUSION: Most infants with BCG- related disease have local or regional disease.

Severe lipoid pneumonia following aspiration of machine oil: successful treatment with steroids.

Lipoid pneumonia in children follows mineral oil aspiration and may result in acute respiratory failure. Majority of the patients recover without long-term morbidity, though a few may be left with residual damage to the lungs. We report a case of a two-and-a-half-year-old child with persistent lipoid pneumonia following accidental inhalation of machine oil, who was successfully treated with steroids.

Berardinelli Seip syndrome with insulin-resistant diabetes mellitus and stroke in an infant.

Berardinelli Seip congenital lipodystrophy (BSCL) is a rare metabolic disorder characterized by severe generalized lipodystrophy, insulin resistance, and dyslipedemia since infancy, and onset of overt diabetes mellitus in adolescence. Here we report a 5-month-old infant with clinical and metabolic manifestations of Berardinelli Seip syndrome including overt diabetes mellitus and stroke, which are very rare at this age.

Intermittent short course therapy for pediatric tuberculosis.

We conducted this study to assess the efficacy of intermittent short course therapy in all forms of pediatric tuberculosis using a coordinated approach with Revised National Tuberculosis Control Programme (RNTCP). Sixty five children were treated using RNTCP protocols with some modifications, such as dose adjustments or prolongation of treatment in selected children. Overall response rate was 95%(pulmonary 94% and extra pulmonary 97%). There was one case with possible relapse. With dynamic inputs from both the treating pediatrician and personnel from Directly Observed Treatment Short course (DOTS) centers, we could successfully implement RNTCP protocols in childhood tuberculosis.

Anemia and growth failure among HIV-infected children in India: a retrospective analysis.

BACKGROUND: Anemia and poor nutrition have been previously described as independent risk factors for death among HIV-infected children. We sought to describe nutritional status, anemia burden and HIV disease correlates among infected children in India. METHODS: We analyzed retrospective data from 248 HIV-infected children aged 1-12 years attending three outpatient clinics in South India (2004-2006). Standard WHO definitions were used for anemia, HIV staging and growth parameters. Statistical analysis included chi square, t tests, univariate and multivariate logistic regression analyses. RESULTS: The overall prevalence of anemia (defined as hemoglobin < 11 gm/dL) was 66%, and 8% had severe anemia (Hb < 7 gm/dL). The proportion of underweight and stunted children in the population was 55% and 46% respectively. Independent risk factors of anemia by multivariate analysis included the pre-school age group (age younger than 6 years) (OR: 2.87; 95% CI: 1.45, 5.70; p < 0.01), rural residence (OR: 12.04; 95% CI: 5.64, 26.00; p < 0.01), advanced HIV disease stage (OR: 6.95; 95% CI: 3.06, 15.79; p < 0.01) and presence of stunting (Height-for-age Z Score < -2) (OR: 3.24; 95% CI: 1.65, 6.35; p < 0.01). Use of iron/multivitamin supplementation was protective against risk of anemia (OR: 0.44; 95% CI: 0.22, 0.90; p = 0.03). Pulmonary tuberculosis was an independent risk factor in multivariate analysis (OR: 3.36; 95% CI: 1.43, 7.89; p < 0.01) when correlated variables such as HIV disease stage and severe immunodeficiency, and nutritional supplement use were not included. Use of antiretroviral therapy (ART) was associated with a reduced risk of anemia (OR: 0.29; 95% CI: 0.16, 0.53; p < 0.01). No significant association was found between anemia and gender, cotrimoxazole, or ART type (zidovudine versus stavudine). CONCLUSION: The high prevalence and strong interrelationship of anemia and poor nutrition among HIV-infected children in India, particularly those living in rural areas underscores the need for incorporating targeted nutritional interventions during national scale up of care, support and treatment among HIV-infected children.

Juvenile Paget's disease.

Juvenile Pagets disease (JPD), a rare genetic disorder characterized by markedly accelerated bone turnover, presents in early childhood. We report a child with typical features of JPD who remained undiagnosed till 15 years of age. Rarity of this disease in Indian literature and need for early diagnosis to prevent progression of disease prompted us to report this case.

Primary hypothyroidism with precocious puberty and bilateral cystic ovaries.

It is a general observation that children with hypothyroidism have delayed sexual maturation and delayed puberty. However, longstanding untreated hypothyroidism could be associated with isosexual precocious puberty. Here we report a nine year old girl with longstanding untreated hypothyroidism presenting with precocious puberty and bilateral multicystic ovaries, which promptly responded to thyroid hormone replacement.

Tuberculosis of the breast in an adolescent girl: a rare presentation.

Tuberculosis (TB) of the breast is a rare condition and usually affects women in the reproductive age group. Its further rarity in children, even in India, where TB is rampant, poses challenges in its diagnosis. Histopathology plays an important role in the diagnosis of this condition. We report a case of TB of the breast in a 15-year-old girl proven by histopathological study.

Do the length-based (Broselow) Tape, APLS, Argall and Nelson's formulae accurately estimate weight of Indian children?

This study was aimed at validating the usefulness of a length based pediatric emergency tape (Broselow) in an Indian population. The secondary objective was to validate age based weight estimation formulae (Nelson, Argalls, APLS) for emergency needs (doses, sizes). This cross sectional study was done at a tertiary teaching hospital on a sample of 500 children attending outpatient clinic. Inclusion criteria was age between 1 month to 12 years. Children who were unstable, uncooperative or critically ill requiring emergency care and those measuring more than 145 cm in length or weighing more than 35 kg weight were excluded from the study. Measurement of actual weights, calculation of weight, adrenaline dose, fluid bolus and endotracheal tube size was done by all four methods. Results indicated good positive correlation between actual measured weights and weights estimated using Broselow Tape (r = 0.974), APLS (r = 0.902), Argalls modification (r = 0.902), and combined Nelson formulae (0.935). However, specific Nelson formulas for 7-12 yr and 3-12 mo were especially poor in correlation. Bland-Altman Plots comparing actual weight showed least mean bias for Broselow Tape estimations in < 15 kg group (0.080 +/- 0.96 kg) and maximum bias with Nelsons formula for 7 to12 yr (5.204 +/- 4.272 kg). For adrenaline doses and fluid bolus calculations, Broselow estimations were valid estimates. Broselow tape did underestimate endotracheal tube size (mean bias -0.53 +/- 0.18). To conclude, length based pediatric emergency tape (Broselow) correlates well with overall emergency decision making process in our setting. This is especially validated in the age group 0.1 to 6.7 yr weighing less than 15 kg.

Congenital Nephrotic Syndrome with adrenal calcification and cardiac malformation.

Congenital Nephrotic Syndrome (CNS) with adrenal calcification and CNS with congenital heart disease (CHD) have rarely been reported. However, CNS with both these rare associations has never been previously reported. Here we report a case of CNS with both rare associations, perhaps the first report from India to the best of our knowledge.
