RESUMO

Background: There is only limited data on the association between psoriasis and metabolic comorbidities in South-Asian children. Objective: To examine metabolic comorbidities among South-Asian children with and without psoriasis. Materials and Methods: A hospital-based, comparative, cross-sectional study was conducted in children with and without psoriasis over 19 months. Anthropometric, clinical, and metabolic comorbidity details (including disease extent and severity scores, obesity, systemic hypertension, diabetes mellitus, lipid abnormalities, and metabolic syndrome) were obtained in both groups according to standard criteria. Results: Fifty-eight children with psoriasis (25 males/33 females, age 11.3 ± 3.0 years, range 4 to 17 years) and 62 children without psoriasis (37 males/25 females, age 11.0 ± 3.6 years, range 4 to 18 years) were recruited. The prevalence of obesity (31.0% versus 14.5%, P = 0.031, odds ratio 2.65) and metabolic syndrome (18.6% versus 4.6%, P = 0.044, odds ratio 4.68) were higher in children with psoriasis than without. The prevalence of other metabolic comorbidities (systemic hypertension, pre-diabetes, lipid abnormalities, elevated serum alanine aminotransferase, and non-alcoholic fatty liver disease) was not different between children with and without psoriasis and between obese and non-obese children with psoriasis. Among children with psoriasis, those with abdominal obesity had significantly lower disease severity and extent scores than those without. Conclusion: Psoriasis is associated with a significantly higher prevalence of obesity and close to significantly higher prevalence of metabolic syndrome in South-Asian children. Screening for metabolic comorbidities is essential even in non-obese children with psoriasis. Disease extent and severity are less in obese compared to non-obese South-Asian children with psoriasis.

RESUMO

PURPOSE OF REVIEW: This review explores the emerging evidence regarding pathogenesis, future trajectories, treatment options, and phenotypes of youth-onset type 2 diabetes (T2D). RECENT FINDINGS: Youth-onset T2D is increasing in incidence and prevalence worldwide, disproportionately affecting First Nations communities, socioeconomically disadvantaged youth, and people of colour. Youth-onset T2D differs in pathogenesis to later-onset T2D and progresses more rapidly. It is associated with more complications, and these occur earlier. While there are limited licensed treatment options available, the available medications also appear to have a poorer response in youth with T2D. Multiple interacting factors likely contribute to this rising prevalence, as well as the increased severity of the condition, including structural inequities, increasing obesity and sedentary lifestyles, and intergenerational transmission from in-utero exposure to maternal hyperglycemia and obesity. Youth-onset T2D is also associated with stigma and poorer mental health, and these impact clinical management. There is an urgent need to develop effective interventions to prevent youth-onset T2D and enhance engagement of affected youth. It is also critical to better understand the differing phenotypes of youth-onset T2D, to effectively target treatments, and to address intergenerational transmission in high-risk populations.

RESUMO

BACKGROUND AND OBJECTIVES: Patient-reported measures of encounters in healthcare settings and consideration of their preferences could provide valuable inputs to improve healthcare quality. Although there are increasing reports of user experiences regarding health care in India in recent times, there is a lack of evidence from Indian healthcare settings on the care provided for patients with chronic diseases. METHODS: We selected diabetes mellitus and cancer as representatives of two common conditions requiring different care pathways. We conducted a scoping review of studies reporting experiences or preferences of patients/caregivers for these conditions, in PubMed, Global Index Medicus and grey literature, from the year 2000 onwards. Both published and emergent themes were derived from the data and summarised as a narrative synthesis. RESULTS: Of 95 included studies (49 diabetes, 46 cancer), 73% (65) were exclusively quantitative surveys, 79% included only patients (75), and 59.5% (44) were conducted in government centres. Studies were concentrated in a few states in India, with the underrepresentation of vulnerable population groups and representative studies. There was a lack of standardised tools and comprehensive approaches for assessing experiences and preferences of patients and caregivers, concerning diabetes and cancers in India. The commonest type of care assessed was therapeutic (74), with 14 cancer studies on diagnosis and nine on palliative care. Repeated visits to crowded centres, drug refill issues, unavailability of specific services in government facilities, and expensive private care characterised diabetes care, while cancer care involved delayed diagnosis and treatment, communication, and pain management issues. CONCLUSIONS: There is a need for robust approaches and standardised tools to measure responsiveness of the healthcare system to patient needs, across geographical and population subgroups in India. Health system reforms are needed to improve access to high-quality care for treatment and palliation of cancer and management of chronic diseases such as diabetes.

RESUMO

Background: The data on the bone mineral density (BMD) and bone turnover markers (BTMs) in Indian adolescents are limited. Objectives: To assess BMD at lumbar spine (LS, L1-L4) and femoral neck (FN) in South Indian post-menarchal girls and correlate it with dietary calcium intake (mg/day), physical activity score and post-menarchal years. The study also assessed serum BTMs and their correlation with chronological age in the study population. Methods: This cross-sectional study included apparently healthy post-menarchal adolescent girls aged 12-16 years randomly selected from the community. Participants with vitamin D deficiency were excluded. The data on calcium intake and physical activity were obtained using validated questionnaires. All participants were evaluated with serum calcium, 25-hydroxy vitamin D, parathyroid hormone, N-terminal propeptide of type 1 collagen (P1NP) and Beta-CrossLaps (CTx) and BMD at LS and FN using dual X-ray absorptiometry (DXA). Statistical Analysis: EpiData version 3.1 was used for the data entry. The data analysis was done using Statistical Package for Social Sciences (SPSS) version 21. Continuous variables were expressed as mean ± SD. Pearson's correlation coefficient (r) was calculated, and two-tailed Kendall's tau-b test was used for assessing correlation of all nonparametric measures. Results: A total of 103 participants were screened, and data from 77 were analysed. There was a significant positive correlation of BMD at LS with chronological age (r: +0.235, P = 0.036), but not at FN. Positive correlation of BMD with increase in post-menarchal years was also noted at LS (r: +0.276, P = 0.015). There was no significant association of BMD with calcium intake and physical activity scores at both sites. There was a significant negative correlation of serum BTMs with age CTx (r: -0.596, P = 0.0001) and P1NP (r: -0.505, P = 0.0001). Conclusion: This study provides insight into the reference BMD range at LS spine and FN in South Indian rural post-menarchal adolescent girls. BMD positively correlated, whereas BTMs negatively correlated with age. The study also provides the first Indian reference range for serum BTMs in this age group.

RESUMO

Hyperhomocysteinemia is a rare neurometabolic syndrome with diverse manifestations in the pediatric age group, thereby posing a diagnostic challenge. Biochemical testing is imperative to guide plan of evaluation, which may include appropriate genetic testing, in inherited disorders. Through this case-based approach, we demonstrate the heterogeneity of clinical presentation, biochemical and genetic evaluation, and treatment strategies that may reverse this condition among children.

RESUMO

OBJECTIVE: Incomplete surgical removal of craniopharyngiomas frequently results in suboptimal oncological control. Radiation therapy is usually offered in these cases to prevent local recurrence of disease; however, the efficacy of radiation is limited by its potential adverse effect, particularly in younger patients. This study was undertaken to compare long-term outcomes and rates of postoperative obesity and endocrinopathy in patients undergoing either upfront adjuvant radiation after surgery, or postoperative surveillance with progression-contingent intervention. METHODS: Thirty-seven patients aged <25 years who had undergone primary incomplete surgical resection of craniopharyngiomas were retrospectively identified and categorized according to the prescribed treatment strategy. Recurrence rates, functional status, neuro-ophthalmologic, and endocrine outcomes were studied in both groups of patients. RESULTS: Twenty-three patients received upfront adjuvant radiation, and 14 patients underwent postoperative surveillance. Adjuvant radiation in the former group was delivered using either conventional (n=10), 3D-conformal (n=4), or fractionated stereotactic (n=9) techniques using a linear accelerator. The mean follow-up duration was 64.7 months (range 14-134 months). Disease progression was significantly higher in patients undergoing surveillance as compared to those undergoing upfront adjuvant radiation (71.4 versus 17.4%; p=0.002). Median progression-free survival times were 129 months and 27 months in the upfront adjuvant radiation and surveillance groups, respectively (p=0.007). In patients undergoing surveillance, 50% ultimately required irradiation, and the median radiation-free survival time in this subgroup was 57 months. Two children in the adjuvant radiation group developed asymptomatic radiation-related vasculopathies on follow-up; however, there were no statistically significant differences between the two groups in terms of visual, functional, or pituitary-hypothalamic function at last follow-up. CONCLUSIONS: In comparison to upfront adjuvant radiation following incomplete craniopharyngioma resection significantly, a strategy of postoperative surveillance resulted in less durable disease control but allowed radiation therapy to be delayed by a median time of 57 months, without significant detriment to global functional, visual, and neuro-endocrinological outcomes. The merits and demerits of either strategy should be carefully considered in the post-surgical management of these patients.

RESUMO

Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder due to enzyme defects in adrenal steroidogenesis. Several genes code for these enzymes, out of which mutations in the CYP21A2 gene resulting in 21 hydroxylase deficiency, contribute to the most common form of CAH. However, pseudogene imposed challenges complicate genotyping CYP21A2 gene, and there is also a lack of comprehensive molecular investigations in other genetic forms of CAH in India. Here, we describe a cost-effective, highly specific, and sensitive Allele Specific PCR (ASPCR) assay designed and optimized in-house to screen eight common pathogenic mutations in the CYP21A2 gene. We have also established and utilized a multiplex PCR assay for target enrichment and Next-generation sequencing (NGS) of CYP11B1, CYP17A1, POR, and CYP19A1 genes. Following preliminary amplification of the functional gene CYP21A2, ASPCR based genotyping of eight common mutations - P30L, I2G, 8BPdel, I172N, E6CLUS (I235N, V236E, M238K) V281L, Q318X, and R356W was carried out. These results were further validated using Sanger and Next-generation sequencing. Once optimized to be specific and sensitive, the advantage of ASPCR in CYP21A2 genotyping extends to provide genetic screening for both adult and paediatric subjects and carrier testing at a low cost and less time. Furthermore, multiplex PCR coupled NGS has shown to be cost-effective and robust for parallel multigene sequencing in CAH.

RESUMO

Aim and Objectives: 1. To study the clinical outcome, growth and glycaemic control, 2. To study the frequency and type of genetic mutations. Methods: This is a retrospective study with a review of data of medical records from 2008 till date. Results: Twelve patients (six males) with neonatal diabetes mellitus (NDM) were identified. Median (interquartile range - (IQR)) age at diagnosis was 72 (31-95) days with a history of consanguinity in 75%. The median birth weight (range) was 2345 (900-3300) g. Follow-up data were available for eight patients with a median age at (IQR) follow-up of 3.3 (3-5.3) years. At follow-up, the mean annual HbA1c was 8.2% at a mean insulin dose of 1.1 U/kg/d. One patient with Wolcott-Rallison syndrome (WRS) and 21α-hydroxylase deficiency had poor growth and intellectual difficulty. The rest demonstrated satisfactory growth with an increase of mean weight centile from 2nd to 13th, height centile from 6.5th to 20th and normal neuro-cognitive development. Eleven patients underwent genetic testing with a molecular diagnosis in 54% (6/11): EIF2AK3 (n = 2) and one each in INS, PDX1, IL2RA and FOXP3. None had variants in ABCC8 or KCNJ11. One with immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome underwent haematopoietic stem cell transplant (HSCT) and later succumbed. Conclusion: Our study demonstrates good clinical outcomes among NDM patients without immune dysfunction. Molecular diagnosis was attained only in around half of the patients (54%) with a great genetic heterogeneity.

RESUMO

BACKGROUND: AICA (5-aminoimidazole-4-carboxamide) ribosiduria is an inborn error in purine biosynthesis caused due to biallelic pathogenic variants in the 5-aminoimidazole-4-carboxamide ribonucleotide-formyltransferase/imp cyclohydrolase (ATIC) gene located on chromosome 2q35. ATIC codes for a bifunctional enzyme, AICAR transformylase and inosine monophosphate (IMP) cyclohydrolase, which catalyse the last two steps of de novo purine synthesis. This disorder has been previously reported in only 4 cases worldwide, and herein, we report the first from India. CASE REPORT: The proband presented with global developmental delay, developmental hip dysplasia (DDH), acyanotic heart disease and nystagmoid eye movements. Whole exome sequencing (WES) identified compound heterozygous pathogenic variants in the ATIC. A novel splice site variant; c.1321-2A > G and a previously reported missense variant; c.1277A > G (p.Lys426Arg) were identified. Segregation analysis of parents showed the father to be a heterozygous carrier for the splice site variant and the mother, a heterozygous carrier for the missense variant. CONCLUSION: This case of a rare genetic disorder of purine biosynthesis of ATIC deficiency is the first case reported from India. Early diagnosis lead to early interventional therapy and genetic counselling.

RESUMO

BACKGROUND: There is limited literature on outcomes after surgical treatment of giant craniopharyngiomas in adult and pediatric patients. METHODS: A retrospective review of 159 patients undergoing surgery for craniopharyngiomas at a single institution was performed. Patients with giant craniopharyngiomas (maximum dimension ≥4.5 cm) were compared with nongiant tumors in terms of various clinical and radiological parameters and long-term surgical outcomes. Extent of resection was determined by postoperative magnetic resonance imaging. Factors associated with post-treatment obesity were also analyzed. RESULTS: Giant craniopharyngiomas (n = 66) were characterized by higher rates of childhood presentation, visual impairment, neurological deficits, multicompartmental involvement, and hydrocephalus as compared with nongiant tumors (n = 139). Giant tumors also were less likely to undergo transsphenoidal resection and were associated with a higher rate of postoperative neurological morbidity. There were no significant differences between the 2 groups in terms of extent of resection, use of postoperative radiation therapy, and long-term endocrinological outcomes. Overall recurrence rates over a mean follow-up period of 4.1 years were similar between giant and nongiant tumors; however, recurrences after presumed gross total resection/near total resection were significantly higher in the former subgroup versus the latter (39.4% vs. 18.4%; P = 0.044). Risk factors for post-treatment obesity in giant craniopharyngiomas included adult age (P = 0.001), preoperative obesity (P = 0.003), and hypothalamic involvement (P = 0.012). CONCLUSION: Gross total resection/near total resection of giant craniopharyngiomas can be achieved at rates comparable to nongiant tumors. However, there remains a greater risk of postoperative neurological morbidity. Radiation therapy mitigates the risk of recurrence on long-term follow-up.

RESUMO

CONTEXT: Wolfram syndrome (WFS) is a rare autosomal recessive disorder characterized by juvenile-onset diabetes, diabetes insipidus, optic atrophy, deafness, and progressive neurodegeneration. However, due to the progressive nature of the disease and a lack of complete clinical manifestations, a confirmed diagnosis of WFS at the time of onset of diabetes is a challenge. OBJECTIVE: With WFS1 rare heterozygous variants reported in diabetes, there is a need for comprehensive genetic screening strategies for the early diagnosis of WFS and delineating the phenotypic spectrum associated with the WFS1 gene variants in young-onset diabetes. METHODS: This case series of 11 patients who were positive for WFS1 variants were identified with next-generation sequencing (NGS)-based screening of 17 genemonogenic diabetes panel. These results were further confirmed with Sanger sequencing. RESULTS: 9 out of 11 patients were homozygous for pathogenic/likely pathogenic variants in the WFS1 gene. Interestingly, 3 of these probands were positive for the novel WFS1 (NM_006005.3): c.1107_1108insA (p.Ala370Serfs*173) variant, and haplotype analysis suggested a founder effect in 3 families from Southern India. Additionally, we identified 2 patients with young-onset diabetes who were heterozygous for a likely pathogenic variant or a variant of uncertain significance in the WFS1 gene. CONCLUSION: These results project the need for NGS-based parallel multigene testing as a tool for early diagnosis of WFS and identify heterozygous WFS1 variants implicated in young-onset diabetes.

RESUMO

Genetic screening of Congenital Adrenal Hyperplasia (CAH) is known to be challenging due to the complexities in CYP21A2 genotyping and has not been the first-tier diagnostic tool in routine clinical practice. Also, with the advent of massive parallel sequencing technology, there is a need for investigating its utility in screening extended panel of genes implicated in CAH. In this study, we have established and utilized an Allele-Specific Polymerase Chain Reaction (ASPCR) based approach for screening eight common mutations in CYP21A2 gene followed by targeted Next Generation Sequencing (NGS) of CYP21A2, CYP11B1, CYP17A1, POR, and CYP19A1 genes in 72 clinically diagnosed CAH subjects from India. Through these investigations, 88.7% of the subjects with 21 hydroxylase deficiency were positive for eight CYP21A2 mutations with ASPCR. The targeted NGS assay was sensitive to pick up all the mutations identified by ASPCR. Utilizing NGS in subjects negative for ASPCR, five study subjects were homozygous positive for other CYP21A2 variants: one with a novel c.1274G>T, three with c.1451G>C and one with c.143A>G variant. One subject was compound heterozygous for c.955C>T and c.1042G>A variants identified using ASPCR and NGS. One subject suspected for a Simple Virilizing (SV) 21 hydroxylase deficiency was positive for a CYP19A1:c.1142A>T variant. CYP11B1 variants (c.1201-1G>A, c.1200+1del, c.412C>T, c.1024C>T, c.1012dup, c.623G>A) were identified in all six subjects suspected for 11 beta-hydroxylase deficiency. The overall mutation positivity was 97.2%. Our results suggest that ASPCR followed by targeted NGS is a cost-effective and comprehensive strategy for screening common CYP21A2 mutations and the CAH panel of genes in a clinical setting.

RESUMO

Aicardi-Goutieres Syndrome (AGS) is a heterogeneous genetic syndrome, manifesting early as encephalopathy and is associated with abnormal neurologic findings, hepatosplenomegaly, elevated liver enzymes, thrombocytopenia and intracranial calcification. The most severe neonatal type, AGS1, is caused by biallelic disease-causing variants in TREX1. In this study, we describe four patients with TREX1-related AGS1 whose phenotype overlaps with intra-uterine infections and neonatal lupus. Exome sequencing identified a previously reported TREX1 variant, c.223dup (NM_016381.5; p. Glu75GlyfsTer82) in all the four patients belonging to the Indian subcontinent. The functional consequence of the disease-causing variant was predicted by using a new combination of bioinformatics softwares. The recurrence of this pathogenic variant indicates a possible founder effect in TREX1 for AGS1 in this population. The phenotypic variability in those with this founder mutation can mimic intrauterine infections and neonatal lupus, thereby leading to misdiagnosis warranting a targeted genetic testing approach to be a part of the diagnostic workup to obtain a definite, early and cost-effective diagnosis in patients from Indian subcontinent with early onset encephalopathy.

RESUMO

INTRODUCTION: Gaucher disease (GD) is a rare autosomal recessive lysosomal storage disorder, in which biallelic pathogenic variants in the Glucosidase beta acid (GBA) gene result in defective functioning of glucosylceramidase that causes deposition of glucocerebroside in cells. GD has 3 major types namely, non-neuronopathic (type I), acute neuronopathic (type II), and chronic neuronopathic (type III). Definite treatment options are limited and expensive. They succumb early to the disease, if untreated. There is paucity of studies from the Indian subcontinent, which elicit the factors resulting in their premature mortality. MATERIALS AND METHODS: A retrospective study was carried out in a tertiary care setting of South India to assess the clinical profile, mutation spectrum, and various management strategies (only supportive therapy, enzyme replacement therapy [ERT], substrate reduction therapy [SRT] haematopoietic stem cell transplant [HSCT]), and mortality predictors of patients with GD from 2004 to 2019. A Kaplan-Meier survival curve was plotted. In silico predictions were performed for novel variants. RESULTS: There were 60 patients with all types of GD seen over the study period of 15 years. Their median age at diagnosis was 2 years. The median follow-up was for 5 years (interquartile range [IQR] = 2-8). The overall mortality rate was 35%; however, it was only 10% in those receiving definite treatment. Mortality was higher (47.5%) by more than 4 folds in those only on supportive therapy. The median survival from the time of diagnosis was 6.3 years (IQR = 3.5-10.8) in the definite treatment group and 3.5 years (IQR = 1-5) in those on supportive therapy. The Kaplan-Meier survival analysis showed significant (p value 0.001) mortality difference between these groups. The multiple logistic regression analysis found the neuronopathic type (OR = 5) and only supportive therapy (OR = 6.3) to be the independent risk factors for premature mortality. CONCLUSION: GD is a rare disease with a high mortality rate, if left untreated. ERT and SRT are the definitive treatments which increase the survival. In resource-limited settings like India, with higher prevalence of the neuronopathic type, HSCT may be a more suitable definitive treatment option, due to its one-time intervention and cost, assuming similar efficacy to ERT. However, the efficacy and safety of HSCT in GD needs to be established further by substantial patient numbers undergoing it.

RESUMO

BACKGROUND AND OBJECTIVES: In our institution, we have an ongoing newborn thyroid screening (NBS) program since July 2001. In the initial 9 months, we used cord blood thyroid-stimulating hormone (TSH) (CBTSH) cutoff of 20 mIU/L and thereafter the cutoff was increased to 25 mIU/L. Our objective was to evaluate whether a CBTSH cutoff of 25 mIU/L is sensitive and cost-effective in NBS of congenital hypothyroidism (CH). MATERIALS AND METHODS: All in-born babies are screened and those with CBTSH ≥25 mIU/L are recalled for confirmatory TSH/T4/FT4 tests. CH is confirmed with elevated TSH and low T4/FT4. Those with CBTSH 20-24.99 mIU/L were recalled for confirmatory tests in initial period of our NBS and prospectively between January and August 2017. Statistical analysis was done to derive positive predictive value and sensitivity to diagnose CH for each CBTSH between 20 and 30 mIU/L. RESULTS: A total of 164,163 neonates were screened from July 2001 to August 2017. Of the 2352 babies with CBTSH ≥25-30 mIU/L, 1763 returned for retesting and 5 confirmed as CH (4 gland-in-situ and 1 absent uptake on nuclear scan). Of the 14,742 screened during the study period, 195 of the 293 babies with CBTSH 20-24.99 mIU/L returned for retesting and none diagnosed as CH. A CBTSH of 25 mIU/L has 99.2% sensitivity and 97.5% specificity. A lower screen TSH cutoff 20 mIU/L would result in recall of additional 300 babies/year with no definite improvement in sensitivity. CONCLUSIONS: Our data justify the continuation of using screen TSH cutoff of 25 mIU/L while using cord blood for NBS in our population. With a diverse and large population, it is important that we use feasible regional screen cutoffs for optimal use of our resources.

RESUMO

BACKGROUND: The optimal management of pediatric craniopharyngiomas remains controversial. This study aimed to characterize long-term outcomes in a contemporary cohort of children undergoing surgery for craniopharyngiomas. METHODS: This was a retrospective review of 37 consecutive children who underwent surgery for craniopharyngioma with a median follow-up duration of 79 months (range 5-127 months). Patients were stratified by extent of resection (EOR) and need for adjuvant radiation therapy (RT). Imaging studies were reviewed to grade extent of hypothalamic involvement. Data on functional outcomes, pituitary function, and obesity were analyzed. RESULTS: Gross total resection was achieved in 16 patients (43.2%), near total resection in six patients (16.2%), and subtotal resection (STR) in 15 patients (40.5%). The recurrence-free survival rate was 81.1% and 70.3% at 5- and 10-year follow-up, respectively. Survival analysis showed superior disease control in patients undergoing STR + RT (p = 0.008). Functional outcomes were independent of EOR, postoperative RT or recurrence. Diabetes insipidus was present in 75% and 44.4% of patients required >2 hormone replacements at last follow-up. Obesity was present in 36.1% patients after treatment, and was associated with preoperative obesity (p = 0.019), preoperative hypothalamic involvement (p = 0.047) and STR + RT (p = 0.011). CONCLUSIONS: Gross or near total resection may be achieved safely in almost 60% of cases; however, radical surgery does not eliminate the risk of recurrence. Over long-term follow-up, STR + RT offers the best disease control rates. Patients with preoperative hypothalamic involvement, obesity, and those with tumors not amenable to radical resection are at risk for developing obesity on long-term follow-up.

RESUMO

BACKGROUND: Glycogen storage disease (GSD) is typified by early morning seizures. Absence of this results in delayed diagnosis, especially the non-GSD 1 group. Data are limited to few patients with unclear outcome. OBJECTIVES: 1. Study the common presentation and types of GSD. 2. Study the clinical and biochemical outcome. 3. Review genetic mutations. METHODS: Observational study from May 2016-April 2019 at metabolic clinic at our center. RESULTS: Total of 30 patients were diagnosed with GSD. Ten were excluded-Fanconi-Bickel (3) and <4 months follow-up (7). Data were analyzed for 20 patients (16 males). Mean age at presentation was 4.3 yrs. All had hepatomegaly, 90% had short stature, and 40% had early morning seizures. Mean follow-up was 22 months. There was a statistically significant improvement in metabolic parameters on treatment (mean)-fasting glucose from 50.4 to 79.5 mg/dl, SGPT from 416 to 199 U/L. Lipid profile showed reduction in triglycerides (318-225 mg/dl) but minimal increase in cholesterol (178-188 mg/dl). Mean weight centile improved from 14.1 to 20.3 and height centile from 2.3 to 7.9. Genetic testing confirmed types VI (3), III (3), IXa (1), IXc (1), and Ia (1). Liver biopsy confirmed GSD in 15/20. All were managed with uncooked corn starch. In addition, omega-3 fatty acid was used in 8/20 and high protein diet in 2 with GSD type III. CONCLUSION: Awareness of GSD needs to improve among pediatricians and hepatologists. The most common symptoms are asymptomatic hepatomegaly and short stature. Dietary therapy with uncooked corn starch remains mainstay of treatment. Mixed hyperlipidemia is difficult to control despite good metabolic improvement. Role of omega-3 fatty acid needs to be explored further. Genetic mutation analysis can assist with tailoring treatment and should get precedence over liver biopsy.
