Clinical profile and natural history of children with HIV infection.

OBJECTIVE: As the HIV infection spreads in India, increasing number of children are affected. We report the clinical manifestations, the laboratory parameters and follow up of these children. METHODS: We reviewed case records of all children diagnosed as pediatric HIV infection since 1995 in our department at a tertiary care hospital in north India. Since September 1999, all children with HIV infection registered in our clinic were prospectively followed up. Complete clinical and laboratory evaluation was performed at baseline and thereafter children were followed up. The children were managed according to standard treatment guidelines. RESULTS: 109 children (82 boys, 27 girls) were diagnosed to have HIV infection. The median (range) age at presentation was 48 months (range: 0.75 months-180 months). Eighty one (74.3%) children acquired the infection vertically. Ninety-one (83.5%) children were symptomatic at time of presentation. The common symptoms in the former were failure to thrive (81.3%), recurrent fever (73.6%), diarrhea (50.5%) and recurrent or persistent pneumonia (44%). All children had poor nutritional status at baseline. Of the 67 children who followed up, 36 were receiving antiretroviral drugs (32 received 3 drugs), while families of 31 children did not opt for antiretroviral therapy. Children receiving antiretroviral therapy showed improvement in nutritional parameters. CONCLUSION: Majority of children with HIV infection presented with various clinical manifestations, poor nutritional status and immunosuppression. Administration of nevirapine based antiretroviral therapy leads to improvement in growth and immune restoration.

Antiretroviral therapy in HIV-1 infected children.

Highly active antiretroviral therapy is beyond reach of most HIV-infected children in developing countries. There is paucity of data on more affordable regimens such as ones based on nevirapine and 2 nucleoside reverse transcriptase inhibitors. We report our experience with the use of antiretroviral therapy in children with HIV-1 infection at a tertiary care hospital in north India. The study subjects were HIV-1 infected children, who were receiving 3-drug antiretroviral therapy for a period of three or more months. The children were regularly followed up for any complications, changes in anthropometry, and changes in CD4 counts. The mean age of children at diagnosis (n=26; 22 boys) was 68.5 +- 33.4 months. These children were followed up for a mean of 19.7 +- 18.7 months. Twenty four children received nevirapine based regimen. There was statistically significant improvement in weight for height and body mass index on follow up. The mean CD4 count changed from baseline (n=24) of 584.3 +- 685.9 mm3 to 614.4 +- 455.7 mm3 (n=15) at last follow up. One child developed minor skin rash in the initial two weeks of starting nevirapine. One child developed pancreatitis. We conclude that administration of nevirapine based ART for HIV-1 infected children is feasible in resource poor setting. There is improvement in growth parameters with use of this therapy.

Neonatal management of the growth-restricted infant.

Close collaboration between obstetricians and neonatologists is essential for proper care of the growth-restricted fetus. A joint decision on the appropriate timing of delivery is made, based on the risk of fetal compromise compared with that of neonatal morbidity. A neonatal resuscitative team should be available at delivery. Gestational assessment, anthropological measurements and physical examination are necessary to confirm the diagnosis of intra-uterine growth retardation and establish the symmetric, asymmetric, combined or dysmorphic classification. Neonatal management requires special attention to a number of significant morbidities that growth-restricted infants are more prone to develop compared with normally grown infants, including asphyxia, meconium aspiration syndrome, respiratory distress syndrome, massive pulmonary haemorrhage, chronic lung disease, hypothermia, hypoglycaemia, hypocalcaemia, polycythaemia-hyperviscosity, intraventricular haemorrhage, sepsis, necrotizing enterocolitis, coagulation abnormalities, and congenital anatomical and genetic abnormalities. Intra-uterine growth retardation is associated with a higher stillbirth rate and infant mortality rate in preterm, term and post-term infants.

Continuous positive airway pressure - a gentler approach to ventilation.

Continuous positive airway pressure (CPAP) has become a useful modality in management of respiratory distress, especially in preterm babies. Main indications for use of CPAP are respiratory distress syndrome (RDS) and apnea of prematurity. It decreases the need of invasive and costly mechanical ventilation. This review details the physiological effects of CPAP, its methods of delivery, and its need in a country like India. It also describes the guidelines for initiating and weaning CPAP. The review concludes that use of CPAP in respiratory distress syndrome is associated with lower rates of failed treatment, decreased incidence of chronic lung disease and lower overall mortality, specially in infants with birth weight above 1500 grams. Early use of CPAP is more beneficial, Surfactant and CPAP act in conjunction for babies with RDS. CPAP is a low-cost, simple and noninvasive option for a country like India, where most places lack facilities of mechanical ventilation. Systematic reviews, randomized and quasi-randomized trials by searching MEDLINE and the Cochrane Library formed the basis of this update.

Survival and morbidity in extremely low birth weight (ELBW) infants.

We report the morbidity and mortality in extremely low birth weight neonates (ELBW) from a tertiary care hospital over seven years (1994-2000). Data regarding maternal and neonatal details was obtained from old records, computer database and medical files. Of the 12,807 live births during this period, 137 (1.07%) were ELBW infants. All of them were managed without surfactant. Overall, 67 infants (48.7%) survived to discharge. The most commonly encountered morbidities were hyperbilirubinemia(65%), respiratory distress(65%), sepsis(52%), intraventricular hemorrhage(29%), pneumonia (25%) and retinopathy of prematurity(24%). Need for resuscitation, pulmonary hemorrhage, seizures, acute renal failure, sclerema and air leak syndromes were significantly associated with mortality. Sepsis accounted for 41% of all deaths while immaturity was the second most important cause, accounting for 24% deaths. The average length of stay for survivors was 49 days (SD +/- 15.9 days)

Polycythemia in the newborn.

Polycythemia is defined as a venous hematocrit above 65%. The relationship between viscosity and hematocrit is almost linear till 65% and exponential thereafter. Increased viscosity of blood is associated with symptoms of hypo-perfusion. The hematocrit in a newborn peaks at 2 hours of age and decreases gradually after that. The etiology of polycythemia is related either to intra-uterine hypoxia or secondary to fetal transfusion. Clinical features related to hyperviscosity may affect all organ systems and this entity should be screened for in high-risk infants. Polycythemia maybe symptomatic or asymptomatic and guidelines for management of both types are provided in the protocol.
