Vitamin D status of pregnant women and their infants in South India: VIPIS study

Background: Aim was to estimate the prevalence of vitamin D deficiency in pregnant women and their infants and to analyse the effect of maternal vitamin D deficiency on the infant.Methods: A prospective study was done in the Department of Obstetrics and Neonatology in a tertiary centre in South India with 150 women seen in the antenatal clinic after 36 weeks of pregnancy were recruited. Serum vitamin D levels were obtained. Babies were followed up and sampled once between 10 and 20 weeks of age for vitamin D, calcium, phosphate and alkaline phosphatase. Vitamin D levels less than 20 ng/ml was considered as deficiency. Analysis of the data was done using SPSS 16.0 version.Results: Vitamin D deficiency was seen in 64.8% of the pregnant women. Follow up of 76 babies showed vitamin D deficiency in 72.6% infants. Significantly high levels of alkaline phosphatase were noted in infants who were born to mothers with vitamin D deficiency, which indicates risk of developing bone disease.Conclusions: This study highlights the high prevalence of Vitamin D deficiency in pregnant women and their infants in South India in a region with abundant sunshine. This study also emphasises treating vitamin D deficiency in pregnancy to reduce the risk of developing rickets in infancy.

Phase Changing Material for Therapeutic Hypothermia in Neonates with Hypoxic Ischemic Encephalopathy – A Multi-centric Study

Objective: To assess the feasibility and safety of coolingasphyxiated neonates using phase changing material baseddevice across different neonatal intensive care units in India.Design: Multi-centric uncontrolled clinical trial.Setting: 11 level 3 neonatal units in India from November 2014 toDecember 2015.Participants: 103 newborn infants with perinatal asphyxia,satisfying pre-defined criteria for therapeutic hypothermia.Intervention: Therapeutic hypothermia was provided usingphase changing material based device to a target temperature of33.5±0.5oC, with a standard protocol. Core body temperature wasmonitored continuously using a rectal probe during the coolingand rewarming phase and for 12 hours after the rewarming wascomplete.Outcome measures: Feasibility measure - Time taken to reachtarget temperature, fluctuation of the core body temperatureduring the cooling phase and proportion of temperaturerecordings outside the target range. Safety measure - adverseevents during coolingResults: The median (IQR) of time taken to reach targettemperature was 90 (45, 120) minutes. The mean (SD) deviationof temperature during cooling phase was 33.5 (0.39) ºC.Temperature readings were outside the target range in 10.8%(5.1% of the readings were <33oC and 5.7% were >34oC). Mean(SD) of rate of rewarming was 0.28 (0.13)oC per hour. Thecommon adverse events were shock/ hypotension (18%),coagulopathy (21.4%), sepsis/probable sepsis (20.4%) andthrombocytopenia (10.7%). Cooling was discontinued before 72hours in 18 (17.5%) babies due to reasons such as hemodynamicinstability/refractory shock, persistent pulmonary hypertension orbleeding. 7 (6.8%) babies died during hospitalization.Conclusion: Using phase changing material based coolingdevice and a standard protocol, it was feasible and safe to providetherapeutic hypothermia to asphyxiated neonates across differentneonatal units in India. Maintenance of target temperature wascomparable to standard servo-controlled equipment.

Background: Percutaneous central line insertion is a common procedure in the neonatal intensive care unit. Case characteristics: A preterm baby, who had a percutaneous central line inserted developed an erythematous swelling over the infraclavicular area. Observation: A diagnosis of abscess was made, and an incision and drainage done that revealed a white fluid with high triglyceride content, confirming lipid extravasation. Outcome: The lesion healed completely few days after removal of the catheter. Message: This case highlights the importance of proper placement and confirmation of central line position.

Perinatal Outcome of Infants Born to Diabetic Mothers in a Developing Country- Comparison of Insulin and Oral Hypoglycemic Agents.

Objective: To study the perinatal outcomes of infants born to mothers with gestational diabetes treated with insulin or oral hypoglycemic agents in a developing country. Design: Prospective observational cohort study. Setting: Tertiary-care perinatal center in southern India. Participants: Babies born to mothers with gestational diabetes. Methods: Maternal details were obtained and physical examination was performed on the neonates. Babies were given hourly feeds soon after birth and blood glucoses checked at 1, 3, 5, 9 and 12 hours of life; hematocrit and calcium levels were also measured. Perinatal outcomes were compared between mothers who required insulin or an oral hypoglycemic agent for treatment of diabetes. Results: Of the 10,394 mothers who delivered during the study period, 574 (5.5%) were diagnosed to have gestational diabetes. 137 were treated with insulin and 141 with oral hypoglycemic agents. 44 (15.8%) babies were born preterm, 97 (35%) were large for gestational age, 13 (4.7%) were small for gestational age and 9 (3.2%) were macrosomic. Hypoglycemia was seen in 26 (9.3%) babies, congenital anomalies in 15 (5.4%) and birth injuries in 7 (2.5%). There was no difference between the two groups in any of the outcomes except for hyperbilirubinemia, which was more in the insulin group (13.7% vs 6.5%, P=0.04). Conclusions: There was no difference in the perinatal outcome whether the mother received insulin or an oral hypoglycemic agent for treatment of gestational diabetes other than the increased incidence of hyperbilirubinemia in the insulin group.

Whole Body Cooling in Newborn Infants with Perinatal Asphyxial Encephalopathy in a Low Resource Setting: A Feasibility Trial.

Objective: To determine the feasibility and safety of whole body cooling in newborn infants with perinatal asphyxial encephalopathy in a low resource setting. Design: Feasibility trial. Setting: Tertiary care perinatal centre. Subjects: Infants born at  35 weeks gestation with perinatal asphyxia were included in the study. Interventions: Infants were cooled to a rectal temperature of 33±0.5°C for 72 hours using cloth-covered ice-gel packs. Vital parameters were monitored continuously. Outcome measures: The primary outcome was the achievement of target temperature within 1 hour of initiation of treatment and maintaining the target temperature for 72 hours. Adverse events and possible complications of hypothermia were the secondary outcomes measured. Results: Twenty infants were included in the study. The mean time taken to achieve target rectal temperature was 52±25 minutes. The mean rectal temperature during cooling was 32.9±0.11ºC. The target temperature could be maintained for 72 hours without difficulty in all babies. Adverse events observed during cooling were thrombocytopenia (25%), sinus bradycardia (25%), deranged bleeding parameters (20%), aposteatonecrosis (15%), hyperglycemia (15%), hypoglycemia (10%), hypoxemia (5%), life-threatening coagulopathy (5%) and death (5%). Shivering was noted in many of the babies, especially in the initial phase of cooling. Conclusion: Whole body cooling in term infants with perinatal asphyxia is achievable, safe and inexpensive in a low-resource setting.

Prevalence of Extendedspectrum β-lactamase Producing Escherichia coli and Klebsiella spp in a Neonatal Intensive Care Unit.

This study reports the prevalence of extended-spectrum β- lactamase producing Escherichia coli and Klebsiella spp among septicemic neonates. Over a five year period, there were 94 isolates of Klebsiella spp and E .coli. Of these, 68 (72.3%) were ESBL producers. Forty (80%) of the Klebsiella spp isolates produced ESBL as compared to 28 (63.6%) of E.coli.

Neonatal hydrothorax following migration of a central venous catheter.

The use of a central venous catheter may occasionally be associated with complications like sepsis, effusions and thrombosis. Migration of the central catheter is an unusual complication that often goes unrecognized. This case report is of a neonate who developed hydrothorax resulting from a migrating central line and highlights the need for a high level of clinical suspicion in diagnosing catheter related problems.

Tyrosinemia type I: a clinico-laboratory case report.

Progressive hepatocellular dysfunction in a neonate, resulting in elevated serum alpha-fetoprotein together with raised blood levels of tyrosine and methionine, a generalized amino aciduria and the absence of urinary delta-aminolevulinic acid and succinylacetone, suggests a diagnosis of tyrosinemia type Ib. Classical tyrosinemia type I arises from a deficiency of fumarylacetoacetate hydrolase while the variant tyrosinemia type Ib results from a deficiency of maleylacetoacetate isomerase.

Short rib polydactyly syndrome-Type I.

Short rib polydactyly syndrome (SRPS) consists of a group of lethal skeletal dysplasias presenting with short limbs and ribs, hypoplastic thorax and polydactyly with or without visceral abnormalities. The authors report a case of SRPS in a fresh stillborn baby who had these features along with dysplastic kidneys. Clinical and radiological findings in this baby were consistent with SRPS - Type I (Saldino-Noonan Type). The diagnosis of SRPS, as in this case, can be made by antenatal ultrasonography.

Neonatal spinal cord injury.

Neonatal spinal cord injury (SCI) is well described in the literature, though its diagnosis is often delayed or missed in the neonatal period. We present a neonate who was referred with upper gastrointestinal bleed and a diagnosis of spinal cord injury was subsequently made clinically and confirmed radiologically.

Safety and immunogenicity of Haemophilus influenzae type B vaccine given in combination with DTwP at 6, 10 and 14 weeks of age.

OBJECTIVE: To assess the immunogenicity and reactogenicity of a tetanus conjugate Haemophilus influenzae type b vaccine (Act-Hib) when extemporaneously mixed and administered as a DTwP-Hib combination using an Indian DTwP vaccine (BE DTwP) in comparison with a licensed DTwP-Hib combination vaccine. METHODS: 378 healthy infants were enrolled and randomly allocated to receive either three doses, at 6, 10 and 14 weeks of age, of Act-Hib in combination with BE DTwP (Group A, n = 160), TetrAct-Hib (Group B, n = 160), or BE DTwP and Act-Hib as separate injections (Group C, n = 58). Sera collected before the first dose and one month after the third dose were tested for antibodies to vaccine antigens. Safety was determined using parental diary cards. RESULTS: Anti-Hib antibody concentrations indicative of short-term protection (> 0.15 g/ml) were elicited in all but one subject in Group A (99.3%), and all subjects in Groups B and C. The concentration of 1 g/ml, considered to provide long-term protection, was achieved in 96.7%, 100% and 98.2% of the infants in Groups A, B and C, respectively. All children displayed satisfactory responses to the three DTwP component antigens, TetrAct-Hib eliciting higher titers against diphtheria and tetanus than BE DTwP. No vaccine-associated serious adverse events occurred. The BE DTwP vaccine was associated with more reports of fever than TetrAct-Hib, but most symptoms were regarded as mild and all resolved without sequelae. CONCLUSIONS: Combining Act-Hib and a local DTwP vaccine did not affect the anti-Hib response. In countries where DTwP vaccine available for use in the EPI program is manufactured by a local or other developing country manufacturer, mixing it with lyophilised Act-Hib is a reasonable option though the immunogenicity may have to be documented before routine use. However, use of TetrAct-Hib combination vaccine would be preferable in view of its lower reactogenicity and superior immunogenicity with respect to diphtheria and tetanus.
