Among 659 infants of 30 weeks' gestation or less born in a regional perinatal centre between 1983 and 1989, 195 were ventilated for four days or more and survived to 28 days, and 87 of these developed chronic lung disease. There was a sevenfold increase in the annual incidence of chronic lung disease over time. During the same period there were significant increases in the number of infants who survived, the incidence of septicaemia, and the use of parenteral lipid emulsions. Chronic lung disease was significantly associated with low birth weight, shorter gestation, duration of ventilation, vaginal delivery, sepsis, and the use of lipid. Respiratory and physiological measurements at 96 hours were significantly worse in infants who subsequently developed chronic lung disease. Initial logistic regression showed that gestation, arterial carbon dioxide tension (PaCO2), and ventilation rate at 96 hours; and birth in 1988 or 1989, were independently associated with chronic lung disease, but when septicaemia and use of lipid during the first 21 days were included, only gestational age (odds ratio 0.64, 95% confidence interval (CI), 0.49 to 0.81 for each week) and use of lipid (odds ratio 8.1, 95% CI, 2.32 to 28.0) remained significantly associated with chronic lung disease. The observed increase in incidence of chronic lung disease in this population was associated with earlier use of parenteral lipids in infants of very low gestation rather than with changes in population, survival, or ventilator treatment of respiratory distress syndrome.

A questionnaire-based retrospective clinical and immunological survey was conducted in 73 males with a definite diagnosis of X-linked agammaglobulinemia based on BTK sequence analysis. Forty-four were sporadic and 29 familial cases. At December 2000, the patients' ages ranged from 2 to 33 years; mean age at diagnosis and mean duration of follow-up were 3.5 and 10 years respectively. After the mid-1980s all but 2 were on intravenous immunoglobulin (IVIG) substitution therapy, with residual IgG >500 mg/dl in 94% of the patients at the time of enrollment. Respiratory infections were the most frequent manifestation both prior to diagnosis and over follow-up. Chronic lung disease (CLD) was present in 24 patients, in 15 already at diagnosis and in 9 more by 2000. The cumulative risk to present at diagnosis with CLD increased from 0.17 to 0.40 and 0.78 when the diagnosis was made at the ages of 5, 10, and 15 years respectively. For the 9 patients who developed CLD during follow-up, the duration of follow-up, rather than age at diagnosis; previous administration of intramuscular immunoglobulin; and residual IgG levels had a significant effect on the development of CLD. Chronic sinusitis was present in 35 patients (48%), in 15 already at diagnosis and in 20 by 2000. Sistemic infections such as sepsis and meningitis/meningoencephalitis decreased over follow-up, probably due to optimal protection provided by high circulating IgG levels reached with IVIG.

Advances in obstetrical and neonatal care have increased the survival of very-low-birth-weight (VLBW) infants, defined as infants weighing < or = 1,500 g at birth, in many populations. To understand the morbidity and survival of VLBW infants in Taiwan, the records of all VLBW admitted to the 12 hospitals with a level II+ or level III neonatal intensive care unit (NICU), at < 7 days of age, from January 1 to December 31, 1996, were collected prospectively. A total of 613 VLBW infants (292 males and 301 females) met the enrollment criteria: 305 cases from the northern region, 181 cases from the central region, and 127 cases from the southern region of Taiwan. The mean birth weight was 1,133 g (range, 368-1,500); the mean gestational age (GA) was 28.9 weeks (range, 21-38). Among the VLBW infants, 25.8% were small-for-gestational-age, 90.2% were born to mothers with high-risk factor(s) for preterm delivery, 55% were born by cesarean section, and 68.1% required resuscitation at birth. The percentage of prenatal use of steroids was 52.9%, and < 20% received more than one dose of antenatal steroids. Thirty-three percent were born after antenatal maternal transfer, and the neonatal transfer rate was 23%. The most common neonatal complication was apnea of prematurity (66.1%), followed by respiratory distress syndrome (RDS) (60%). Chronic lung disease occurred in 76 cases (16.5%). The overall survival rate of the 613 VLBW infants was 76.2%; for infants weighing < or = 1000 g at birth, it was 49.2%, and for infants weighing 1,001-1,500 g at birth, it was 88.5%. The survival rate for infants with a GA < or = 26 weeks was 35.3%, and for infants with a GA of 27-36 weeks was 87.5%. No infant with a birth weight < or = 600 g or a GA < 23 weeks survived. The most common cause of death was sepsis, followed by extreme prematurity (GA < or = 23 wks) and RDS. Several perinatal and neonatal factors were related to the mortality. Multiple regression analysis of survival showed that GA < or = 26 weeks, birth weight < or = 800 g, delivery room resuscitation and the occurrence of pneumothorax were related to mortality. Therefore, although the survival rate of VLBW infants admitted to level II(+)-III NICUs showed an improvement over the rate for the previous 20 years in Taiwan, perinatal and neonatal care of extremely preterm infants and neonatal resuscitation programs need to be emphasized to improve the outcome of VLBW infants furthermore.
