RESUMO

AIM: To develop a score based on clinical and laboratory parameters in acute-phase of GBS to predict outcome at 6 months. METHODS: Clinical and laboratory assessment at admission including blood neutrophil-to-lymphocyte ratio (NLR), pre and post-immunotherapy serum albumin was prospectively performed in pediatric-GBS cases at a tertiary-care hospital over 1 year. Clinical features and laboratory test results were compared between children with complete (Hughes Disability Score; HDS ≤ 1) and incomplete recovery (HDS > 1) at 6 months from onset, using univariate and multivariate analysis. Area-under-receiver-operating-characteristic-curve (AUC) of predictors of prognosis and their optimal cutoffs were assessed. RESULTS: Forty-six patients were enrolled (mean age 69.1 ± 35.2 months; male 57.6%). Factors on admission that independently predicted poor-outcome at 6 months were older age, feeble voice, lower NLR and lower post-immunotherapy serum albumin. AUCs and optimal cutoffs of NLR and post-immunotherapy serum albumin for predicting disability at 6 months were 0.729, 0.781 and ≤ 1.65, ≤ 34.5 g/L, respectively. AUCs of clinical parameters such as older age and feeble voice were 0.749 and 0.713 respectively. King GBS outcomescore including all predictors had maximum AUC of 0.971 (95% CI 0.921-1.02). The score at cutoff ≥ 3 demonstrated excellent sensitivity (92.3%) and specificity (96.7%) to determine poor outcome. CONCLUSIONS: This new prognostic system may be beneficial in recognising children-at-risk of poor prognosis who may benefit from additional treatment.

RESUMO

OBJECTIVE: To describe the clinical-laboratory profile of pediatric Guillain-Barre syndrome and delineate features associated with need of mechanical ventilation. METHODS: In a prospective observational study at tertiary care hospital, clinical-laboratory assessment and nerve conduction studies were documented in consecutive children hospitalized with Guillain-Barre syndrome according to Brighton criteria. Clinical-laboratory features were compared between ventilated and nonventilated patients using univariate and multivariate analysis. RESULTS: Forty-six children (27 boys) with a mean age of 69.1±35.2 months were enrolled. History of preceding infection was present in 47.8%, bulbar palsy in 43.5%, feeble voice in 41.3%, sensory involvement in 13%, and autonomic involvement in 39.5%. Tetraparesis was noted in 87% of cases. Hughes disability scale >3 was noted in 44 children at admission and 39 (84.7%) at discharge. The most common electrophysiological type was acute motor axonal neuropathy (46.5%) followed by acute motor sensory axonal neuropathy (39.5%), acute inflammatory demyelinating polyneuropathy (7%), and inexcitable nerves (7%). Nine (19.7%) children were ventilated, 3 (6.5%) died or were lost, and 43 were discharged. Factors associated with need of mechanical ventilation on univariate analysis were older age, hypertension, bulbar palsy, feeble voice, lower Medical Research Council (MRC) sum, raised total leucocyte count, and history of preceding infection. Logistic regression revealed older age, history of predisposing illness, lower MRC sum at presentation, and bulbar palsy as independent predictors of mechanical ventilation. CONCLUSIONS: The most common electrophysiological subtype in northern Indian children is acute motor axonal neuropathy. Older age, preceding infection, low MRC sum, and bulbar palsy are predictors of mechanical ventilation in pediatric Guillain-Barre syndrome.

RESUMO

Severe acute malnutrition (SAM) is a major cause of child mortality and morbidity. Children treated for SAM are at risk of refeeding hypophosphataemia (HP). The study was done to find out the incidence and various predictors of moderate/severe HP in SAM among North Indian children. This prospective observational study was conducted from August 2014 to July 2015 in the inpatients' department of Department of Paediatrics at King George's Medical University, Lucknow, Uttar Pradesh, North India, a tertiary care teaching hospital. Before inclusion, ethical approval and written informed consent was obtained. Included in the study were sixty-five children aged 6-59 months of age, who were admitted to the hospital with SAM as per the WHO guidelines. SAM was defined as a mid-upper arm circumference <115 mm and/or weight-for-height/length <-3 z-scores of the WHO growth standards and/or have bilateral oedema. Serum P levels were measured on admission and for five consecutive days after starting feed. HP was defined as mild, moderate and severe with a cut-off of 1·19-0·65, 0·65-0·32 and <0·32 mmol/l, respectively. About 60 % children had HP, with 20 % having moderate/severe HP at admission. The proportion of HP increased to 83·1 %, with 38·5 % having moderate/severe HP on day 3 after feeding. It was concluded that HP is a common biochemical abnormality in SAM. Considering its impact on the health of the child, serum P levels should be monitored in patients with SAM who are treated with enteral feeding.

RESUMO

INTRODUCTION: Spotted Fever Rickettsiosis (SFR), an acute febrile illness caused by Rickettsia rickettsii, R. conorii and R. akari which is associated with considerable morbidity and mortality. SFR is one of the most covert emerging infections of the present time which is prevalent in various parts of India as shown by the increase in the number of clinically diagnosed patients in various states except Uttar Pradesh. AIM: To diagnose SFR in clinically suspected patients using serological tests and recognition of common epidemiologic situations and clinical manifestations of SFR in the state of Uttar Pradesh. MATERIALS AND METHODS: Patients of all age groups presented with a diagnosis of Pyrexia of Unknown Origin (PUO) from May 2013 to February 2015 were evaluated. Testing was done using a nonspecific Weil felix test followed by more specific Enzyme Linked Immunosorbent Assay (ELISA) and a gold standard Immunofluorescence Assay (IFA) test for specific IgM antibodies against Rickettsia conorii. The data was statistically analysed on Graph Pad Prism (5.0) software by using Chi-square test. RESULTS: Of the 432 patient samples tested by non specific Weil felix test, 200 (46.29 %) samples showed titre 1:80 or more and were taken as positive. Similarly out of the 432 blood samples tested by both ELISA and IFA based test against Rickettsiaconorii IgM antibody, only 115 (26.62%) samples were found to be positive and these samples were also positive by Weil felix. The common symptoms noted were fever, hepatomegaly, thrombocytopenia, lymphadenopathy and rashes, nausea followed by icterus, cyanosis, headache, oedema and abdominal pain. Eschar was found in only four (3.4%) patients. We also found that 31 patients with SFR also had associated co-infections like typhoid, malaria, dengue and hepatitis. CONCLUSION: Our findings demonstrated that Weil Felix test can fill in as an underlying yet not sole strategy to perceive and analyse rickettsial ailments, as it needs specificity. So, it may be used to assess the burden in the area and later on other tests like ELISA or IFA can be added, as these are more specific diagnostic tests. Further, our results also showed that if a patient tests positive for the more common endemic infections, we must test for rickettsiosis so that appropriate treatment could be administered.

RESUMO

OBJECTIVE: This study aimed to find out incidence, predictors, onset and severity of respiratory distress including meconium aspiration syndrome (MAS) among vigorous neonates born through meconium stained amniotic fluid (MSAF), which may or may not be evident at birth. METHODS: Two hundred ninety vigorous neonates were studied. Data were collected on perinatal risk factors, clinical course and development of respiratory distress. Predictors of respiratory distress were identified by logistic regression and a score based on adjusted OR was assigned for each. Diagnostic performance of the score (0-24) was assessed on another 247 vigorous neonates using receiver operator characteristic analysis (ROC). RESULTS: Respiratory distress developed in 97(33.4 %) infants, MAS in 75(25.9 %). The distress appeared within 12 h in 97.9 %, was severe in only 21.7 %. Of 10 risk factors significantly associated with respiratory distress, seven entered in regression analysis. Fetal distress(adj OR = 11.8; 95%CI = 6.2-22.5), prolonged labor(adj OR = 5.2; 95%CI = 2.5-10.7), and absent/poor cry(adj OR = 5.6; 95%CI = 2.4-13.3) were identified as independent predictors; each assigned a score of 12, 6 and 6, respectively. To predict respiratory distress, a cut-off score of 9 points had sensitivity-74.1 % (95%CI = 63.3 %-82.7 %), specificity-84.6 % (95 % CI = 77.9 %-89.6 %), positive predictive value- 71.6 % (95%CI = 60.8 %-80.4 %), negative predictive value- 86.2 % (95 % CI = 79.6 %-90.9 %), likelihood ratio (LR) + ve 4.8(95%CI = 3.3-7.0) and LR-ve 0.3(95%CI = 0.2-0.4). CONCLUSIONS: Respiratory distress occurred in one third neonates, mostly had onset within 12 h of birth, and it was mild to moderate in majority. Fetal distress, prolonged labor, and absent/poor cry predicted respiratory distress and were validated. However, larger studies in different settings are required to confirm its utility.
