Predictors of death in infants with probable serious bacterial infection.

BackgroundBacterial infections account for a significant proportion of neonatal and infant mortality globally. We aimed to identify predictors of death in infants with probable serious bacterial infection (PSBI) defined as signs/symptoms of possible serious bacterial infection along with baseline C-reactive protein (CRP) ≥12 mg/l.MethodsWe did a secondary analysis using the data collected from 700 infants with PSBI who participated in a randomized controlled trial in India in which zinc or placebo was given in addition to the standard antibiotics. Logistic regression was used to estimate the associations between relevant variables and death within 21 days.ResultsThose infants who were fed cow's milk or formula before the illness episode had 3.7-fold (95% confidence interval (CI) 1.5-9.3) and 5.3-fold (95% CI 2.0-13.6) higher odds of death, respectively. Lethargy (odds ratio (OR) 2.4, 95% CI 1.1-5.4) and CRP (OR 1.9, 95% CI 1.1-3.3) were also independent predictors of death. In the model including only clinical features, female gender (OR 2.25, 95% CI 1.0-5.0), abdominal distention (3.7, 95% CI 1.1-12.3), and bulging fontanelle (5.8, 95% CI 1.1-30.5) were also independent predictors for death.ConclusionFormula or cow milk feeding prior to the illness, lethargy at the time of presentation, and high serum CRP levels predicted death in infants with PSBI.

Efficacy of Oral Zinc Supplementation in Radiologically Confirmed Pneumonia: Secondary Analysis of a Randomized Controlled Trial.

Objective: To evaluate the effect of zinc as an adjuvant therapy in radiologically confirmed pneumonia in children 2-24 months of age. Patients and Methods: We analyzed data of 212 children with pneumonia for whom chest X-ray films were available at enrollment and at least two radiologists agreed on the diagnosis of pneumonia. We compared the time to recovery in the two groups (n = 121, zinc group and n = 91, placebo group) using a Cox proportional hazards regression model. Results: Time to recovery was similar in both groups [median interquartile range: zinc, 84 h (64, 140 h); placebo, 85 h (65, 140 h)]. The absolute risk reduction for treatment failure was 5.2% (95% confidence interval: -4.8, 15.1) with zinc supplementation. Conclusion: There was no significant beneficial effect of zinc on the duration of recovery or risk of treatment failure in children with radiologically confirmed pneumonia.

Zinc as adjunct treatment in infants aged between 7 and 120 days with probable serious bacterial infection: a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Serious bacterial infections are a major cause of death in early infancy in developing countries. Inexpensive and accessible interventions that can add to the effect of standard antibiotic treatment could reduce infant mortality. We measured the effect of zinc as an adjunct to antibiotics in infants with probable serious bacterial infection. METHODS: In this randomised, double-blind, placebo-controlled trial, we enrolled infants aged 7-120 days with probable serious bacterial infection at three hospitals in New Delhi, India, between July 6, 2005, and Dec 3, 2008. With computer-generated sequences, we randomly assigned infants in permuted blocks of six, stratified by whether patients were underweight or had diarrhoea at enrolment, to receive either 10 mg of zinc or placebo orally every day in addition to standard antibiotic treatment. The primary outcome was treatment failure, which was defined as a need to change antibiotics within 7 days of randomisation, or a need for intensive care, or death at any time within 21 days. Participants and investigators were masked to treatment allocation. All analyses were done by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT00347386. FINDINGS: 352 infants were randomly assigned to receive zinc and 348 to placebo. 332 given zinc and 323 given placebo could be assessed for treatment failure. Significantly fewer treatment failures occurred in the zinc group (34 [10%]) than in the placebo group (55 [17%]; relative risk reduction 40%, 95% CI 10-60, p=0·0113; absolute risk reduction 6·8%, 1·5-12·0, p=0·0111). Treatment of 15 (95% CI eight to 67) infants with zinc would prevent one treatment failure. Ten infants receiving zinc died compared with 17 given placebo (relative risk 0·57, 0·27-1·23, p=0·15). INTERPRETATION: Zinc could be given as adjunct treatment to reduce the risk of treatment failure in infants aged 7-120 days with probable serious bacterial infection.

Myelofibrosis: a cause of increased transfusion requirement in a child with ß-thalassemia intermedia.

A 10-year-old girl presented with gradually increasing pallor and abdominal distension for 1 year and fever for 6 months. She required 3 packed cell transfusions during this interval. Investigations done revealed that the child had thalassemia intermedia and parents were carrier of ß-thalassemia gene. The increased transfusion requirement in this case prompted further investigations, which revealed the presence of myelofibrosis. Case reports of myelofibrosis and myelodysplastic syndromes with acquired hemoglobin disorders exist in literature, especially α-thalassemia. To the best of our knowledge, this is the first reported case of ß-thalassemia intermedia in association with myelofibrosis.

Steroid-resistant nephrotic syndrome associated with steroid sulfatase deficiency-x-linked recessive ichthyosis: a case report and review of literature.

UNLABELLED: Nephrotic syndrome associated with X-linked recessive ichthyosis due to steroid sulfatase deficiency has rarely been reported in English literature. We describe a 4 and a half-year-old boy presenting with steroid-resistant nephrotic syndrome (SRNS) with an underlying ichthyotic skin present since birth. Renal biopsy revealed minimal change disease. As many of the male members of the family also showed similar skin manifestations, genetic analysis was done on the patient, which revealed deletion of the steroid sulfatase (STS) gene spanning both the 3' as well as the 5'ends. The patient was thus diagnosed with SRNS associated with X-linked recessive ichthyosis. He was started on cyclosporine regimen, and remission was achieved in 5 weeks. We speculate that the deficiency of STS resulting in increased cholesterol sulfate accumulation interferes with the integrity of adherens junctions present between glomerular epithelial cells of the slit diaphragm, and this results in proteinuria and nephrotic syndrome. The nephrotic syndrome remitted with a calcineurin inhibitor medication. CONCLUSION: We suggest that the deficiency of STS is another one in an increasing list of genetic causes of podocytopathy and nephrotic syndrome. Remission of proteinuria in such a case may be achieved with immunosuppressive medication.

Refractory pancytopenia and megaloblastic anemia due to falciparum malaria.

Anemia is a common complication in malarial infection. Direct destruction and ineffective erythropoesis does not adequately explain the cause of anemia in malaria. We present a case with refractory megaloblastic anemia with asymptomatic falciparum malaria. We hypothesize that promoter variants in the inducible nitric oxide synthase gene might be the cause of severe refractory megaloblastic anemia and pancytopenia in our patient. Malaria should always be kept in mind as a cause of anemia especially in endemic areas even if the child is asymptomatic or there is no demonstrable parasite on routine smear examination.

Predictors of poor outcome in children with steroid sensitive nephrotic syndrome.

BACKGROUND AND OBJECTIVE: Nearly 50% of the children with steroid sensitive nephrotic syndrome (SSNS) have a frequently relapsing (FR) or steroid dependent (SD) course, experiencing steroid toxicities and complications of immunosuppression. The study aimed to compare parameters between children with infrequent relapsing (IFR) and FR/SD nephrotic syndrome and to identify the factors associated with a FR/SD course. METHODS: A retrospective analysis of medical records from 2009 to 2014, of children with SSNS attending the pediatric nephrology clinic in a tertiary care medical college and hospital. RESULTS: Out of 325 children (226 males) with SSNS, 213 were IFR and 112 were FRNS/SDNS. The median age of onset was 34 (IQR 24-48) months. The median time to the first relapse was 4 (IQR 3-7) months and 6 (IQR 4-12) months in FR/SD and IFR group respectively. Multivariate logistic regression analysis showed "adequate treatment (≥12 weeks) of the first episode" (odds ratio 0.56, 95% CI 0.34-0.91; p value=0.02) and "shorter median time to the first relapse" (odds ratio 1.04, 95% CI=1.01-1.08; p value=0.04) to be independent predictors of FR/SD course. An ROC curve was constructed which showed that time to first relapse <5.5 months was associated with a sensitivity of 69% and specificity of 60% in predicting a FR/SD course. CONCLUSION: Adequate treatment of the first episode is associated with less chance of an FR/SD course. After treatment of first episode, the first relapse occurring within 5.5 months may predict a frequently relapsing or steroid dependent course.

The impact of pediatric nephrotic syndrome on parents' health-related quality of life and family functioning: an assessment made by the PedsQL 4.0 family impact module.

The multi-dimensional impact on the quality of life (QOL) of families of children with the nephrotic syndrome (NS) has not been studied sufficiently in the literature. We aimed to study this aspect and the predictors of poor QOL among Indian families having children with NS. A cross-sectional study was conducted to compare the parents of children with chronic NS on treatment for at least one year with parents of a matched healthy control group. The parents of both groups were asked to complete the standard self-administered multi-dimensional questionnaire of Pediatric Quality of Life Inventory 4 (PedsQL TM ) Family Impact Module (FIM). Descriptive and analytical statistics were performed to compare scores between the two groups. Possible predictors of poor outcome in each of the summary scales among the cases were assessed by both univariate and multivariate analysis. The parents of 61 cases and 72 controls completed the PedsQL TM FIM questionnaire. The scores in each of the categories, namely FIM Total Scale Score, Parent HRQOL Summary Score, Family Functioning Summary Score and eight individual domains, were found to be significantly higher among controls. Female gender of the affected child was an independent risk factor for poor Family Functioning Summary Score. Also, presence of serious complications during the course of the disease independently predicted poor Total FIM and Parent HRQOL Summary Scores. Even a relatively benign and potentially curable chronic disorder in children, like the NS, can disturb the QOL of parents in multiple domains of functioning.

Predictors of time to recovery in infants with probable serious bacterial infection.

INTRODUCTION: Serious bacterial infections continue to be an important cause of death and illness among infants in developing countries. Time to recovery could be considered a surrogate marker of severity of the infection. We therefore aimed to identify clinical and laboratory predictors of time to recovery in infants with probable serious bacterial infection (PSBI). METHODS: We used the dataset of 700 infants (7-120 days) enrolled in a randomised controlled trial in India in which 10mg of oral zinc or placebo was given to infants with PSBI. PSBI was defined as signs/symptoms of possible serious bacterial infection along with baseline C-reactive protein(CRP) level >12mg/L. Time to recovery was defined as time from enrolment to the end of a 2-day period with no symptoms/signs of PSBI and daily weight gain of at least 10g over 2 succesive days on exclusive oral feeding. Cox proportional hazard regression was used to measure the associations between relevant variables and time to recovery. RESULTS: Infants who were formula fed prior to illness episode had 33% longer time to recovery (HR-0.67, 95%CI-0.52, 0.87) than those who were not. Being underweight (HR-0.84, 95%CI-0.70, 0.99), lethargic (HR-0.77, 95%CI-0.62, 0.96) and irritable (HR-0.81, 95%CI-0.66, 0.99) were independent predictors of time to recovery. Baseline CRP was significantly associated with time to recovery (P<0.001), higher CRP was associated with longer time to recovery and this association was nearly linear. CONCLUSION: Simple clinical and laboratory parameters such as formula feeding prior to the illness, being underweight, lethargic, irritable and having elevated CRP levels could be used for early identification of infants with PSBI at risk for protracted illness and could guide prompt referral to higher centers in resource limited settings. This also provides prognostic information to clinicians and family as longer recovery time has economic and social implications on the family in our setting.

Efficacy of zinc given as an adjunct in the treatment of severe and very severe pneumonia in hospitalized children 2-24 mo of age: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Pneumonia is a leading cause of death; in India, an estimated 370,000 children die of pneumonia each year. Zinc has multiple influences on the immune response to infections. Zinc supplementation has been shown to prevent diarrhea and pneumonia in children. However, zinc's therapeutic effect on respiratory infections is less clear. OBJECTIVE: We evaluated the role of zinc as an adjunct to antibiotics in the treatment of children hospitalized for severe or very severe pneumonia. DESIGN: In this randomized, double-blind, placebo-controlled trial, we enrolled 550 children aged 2-24 mo with severe or very severe pneumonia. Within each hospital and pneumonia-severity stratum, children were randomly assigned to receive zinc (20 mg elemental zinc/d) or a placebo in addition to antibiotics and supportive care. RESULTS: The time to recovery from severe or very severe pneumonia was similar in both groups (HR: 0.98; 95% CI: 0.82, 1.17). In the stratified analysis, zinc was shown to be efficacious in reducing the time to recovery in children with very severe pneumonia (HR: 1.52; 95% CI: 1.03, 2.23); however, the effect was no longer statistically significant after adjustment for differences in severely underweight children in the 2 groups. CONCLUSIONS: This study showed no overall benefit of the addition of zinc to antibiotics in reducing the time to recovery from pneumonia but showed a possible benefit of zinc supplementation in a subgroup of children with very severe pneumonia. Additional research is needed in specific subgroups such as children with very severe pneumonia. This trial was registered at http://www.controlled-trials.com as ISRCTN48954234.

Tetanus - still a scourge in the 21st century: a paediatric hospital-based study in India.

Tetanus remains endemic in India. A retrospective hospital-based study was conducted to review the profile of all children admitted with diagnosis of tetanus between January 2009 and December 2010. A total of 140 cases of tetanus were admitted; 45 cases of neonatal tetanus (NT) and 77 cases of post-neonatal tetanus (PNT) were studied. Age of presentation of NT was 9.4 ± 1.2 days. Home-delivered children accounted for 86.7% of cases, with 77.8% being attended by untrained birth attendants. Unimmunized mothers accounted for 93.4%. In PNT, otogenic route of infection and trauma were present in 58.4% and 23.3% of cases, respectively. The rate of hospital admission of tetanus remains high. Unlike previously published reports, otogenic route is the most common mode of PNT infection in this study. Improving immunization, increasing deliveries by skilled birth attendants and prompt treatment of suppurative otitis media are the main areas in which public health initiatives need to be focused.

Clinical and laboratory observation systemic lupus erythematosus and acute lymphocytic leukemia: An unusual case.

The association of systemic lupus erythematosus (SLE) and myeloproliferative and lymphoproliferative malignancies is widely reported. There is scarce information available with regards to the association of SLE and malignancy in children. Usually, SLE precedes the onset of lymphoproliferative disease, but the neoplasia can occur earlier or even simultaneously. There are only five pediatric cases of SLE and associated acute lymphoblastic leukemia (ALL) reported in literature. All of these except one satisfied the revised American College of Rheumatology Criteria for SLE. Three of these cases developed SLE several years after successful treatment of ALL. While two cases reported had simultaneous onset of SLE and ALL, one of the cases in this two-patient series, did not fulfill ≥4 criteria for diagnosis of SLE. We present a case of a 3-year-old boy with SLE and coexistent ALL. To the best of our knowledge, only two such cases of simultaneous presentation of both these diseases are present in literature.

Cumulative cardiac toxicity of sodium stibogluconate and amphotericin B in treatment of kala-azar.

Kala-azar or visceral leishmaniasis is a disseminated protozoal infection caused by parasites of the genus Leishmania (Leishmania donovani in India). Conventional therapy for visceral leishmaniasis continues to be pentavalent antimony (sodium antimony gluconate [SAG]). Amphotericin B is widely used for SAG-unresponsive cases and sometimes even as a first-line drug, especially in endemic areas. With the conventional regimen of SAG, cardiac toxicity has been reported in 8% to 17% of cases with 5% to 7% of them having fatal toxicity. Cardiac toxicity is uncommon with amphotericin B with only few isolated reports. We report some patients with kala-azar in whom coadministration of SAG and amphotericin B led to arrhythmia and sudden death.
