ABSTRACT
OBJECTIVES: To define the vitamin B12 levels and other micronutrients status in severe acute malnutrition (SAM) children. METHODS: This was a prospective hospital based cross-sectional study. INCLUSION CRITERIA: Children with severe acute malnutrition as per WHO criteria. EXCLUSION CRITERIA: (i) Pernicious anemia (ii) Autoimmune gastritis (iii) SAM children on exclusive vitamin B12 supplementation. All enrolled children underwent a detailed clinical history, general physical examination with more emphasis on clinical features of vitamin B12 and other micronutrients deficiencies. Three ml of venous blood was collected to estimate vitamin B12 and other micronutrients. Primary outcome was percentage of deficiency of serum vitamin B12, zinc, copper, selenium, manganese, molybdenum and cobalt in SAM children. RESULTS: Fifty children were included in the study. The mean age of children was 15.60±12.90 mo with male to female ratio 0.85:1. The common clinical presentation in order of frequency were upper respiratory infection (URI) symptoms 35 (70%), hepatomegaly 24 (48%), Hyperpigmentation 17 (34%), angular cheilitis 14 (28%), tremors 11 (22%), edema 07 (14%), and hypotonia 05 (10%). Anemia was found in 44 (88%) children. Prevalence of vitamin B12 deficiency was 34%. Other micronutrient deficiencies observed were cobalt 24 (100%), copper 05 (12%), zinc 04 (9.5%), and molybdenum 03 (12.5%). No statistical significance was found between clinical symptoms and levels of vitamin B12 with different age and sex. CONCLUSIONS: Prevalence of low vitamin B12 and cobalt were more common than other micronutrients.

OBJECTIVE: To determine the utility of CSF Xpert MTB/RIF (GeneXpert) in diagnosis of tubercular meningitis in children in the age group of 2 mo to 12 y. METHODS: This hospital based prospective observational study was conducted at Department of Pediatrics, Karnataka Institute of Medical Sciences (KIMS), Hubli from December 2015 through November 2016. All children with clinically suspected tuberculous meningitis (TBM) were included in the study. These children underwent a detailed history taking, clinical examination, blood investigations, lumbar puncture and CT brain. Cerebrospinal fluid (CSF) samples were sent for CSF GeneXpert examination. Statistical analysis was done using IBM SPSS Statistics Version 20. RESULTS: A total of 28 children were enrolled in the study. Six (21.4%), 4 (14.3%) and 18 (64.3%) cases were definite, probable and possible TBM cases respectively. Most common age group affected was <5 y (83.33%) with median age 2.5 y (IQR 4.875). Male:female ratio was 1.5:1. CSF GeneXpert was tested positive in 6 cases (21.4%). The sensitivity of the test against the clinical scoring (>/=10) was 46.15% (95% CI, 19.22-74.87) and specificity was 100% (95% CI, 78.20-100). There was a significant association between CSF GeneXpert and Mantoux test (P = 0.002), CSF cell type >50% lymphocytes (P = 0.005) and CSF protein >100 mg/dl (P = 0.025) along with CT hydrocephalus (P = 0.021), granuloma (P = 0.009) and basal exudates (P = 0.025). None of the cases were tested smear positive for acid-fast bacilli (AFB). CONCLUSIONS: CSF GeneXpert is superior to smear for AFB in TBM.
