Safety and efficacy of filtered sunlight in treatment of jaundice in African neonates.

ABSTRACT: Evaluate safety and efficacy of filtered-sunlight phototherapy (FS-PT).Term/late preterm infants #14 days old with clinically significant jaundice, assessed by total bilirubin (TB) levels, were recruited from a maternity hospital in Lagos, Nigeria. Sunlight was filtered with commercial window-tinting films that remove most UV and significant levels of infrared light and transmit effective levels of therapeutic blue light. After placing infants under an FS-PT canopy, hourly measurements of axillary temperatures, monitoring for sunburn, dehydration, and irradiances of filtered sunlight were performed. Treatment was deemed safe and efficacious if infants were able to stay in FS-PT for $5 hours and rate of rise of TB was ,0.2 mg/dL/h for infants #72 hours of age or TB decreased for infants .72 hours of age.A total of 227 infants received 258 days of FS-PT. No infant developed sunburn or dehydration. On 85 (33%) of 258 treatment days, infants were removed briefly from FS-PT due to minor temperature-related adverse events. No infant met study exit criteria. FS-PT was efficacious in 92% (181/197) of evaluable treatment days. Mean 6 SD TB change was –0.06 6 0.19 mg/dL/h. The mean 6 SD (range) irradiance of FS-PT was 38 6 22 (2–115) mW/cm2/nm, measured by the BiliBlanket Meter II.With appropriate monitoring, filtered sunlight is a novel, practical, and inexpensive method of PT that potentially offers safe and efficacious treatment strategy for management of neonatal jaundice in tropical countries where conventional PT treatment is not available.

Project description:BackgroundSevere neonatal jaundice and its progression to kernicterus is a leading cause of death and disability among newborns in poorly-resourced countries, particularly in sub-Saharan Africa. The standard treatment for jaundice using conventional phototherapy (CPT) with electric artificial blue light sources is often hampered by the lack of (functional) CPT devices due either to financial constraints or erratic electrical power. In an attempt to make phototherapy (PT) more readily available for the treatment of pathologic jaundice in underserved tropical regions, we set out to test the hypothesis that filtered sunlight phototherapy (FS-PT), in which potentially harmful ultraviolet and infrared rays are appropriately screened, will be as efficacious as CPT.Methods/designThis prospective, non-blinded randomized controlled non-inferiority trial seeks to enroll infants with elevated total serum/plasma bilirubin (TSB, defined as 3 mg/dl below the level recommended by the American Academy of Pediatrics for high-risk infants requiring PT) who will be randomly and equally assigned to receive FS-PT or CPT for a total of 616 days at an inner-city maternity hospital in Lagos, Nigeria. Two FS-PT canopies with pre-tested films will be used. One canopy with a film that transmits roughly 33% blue light (wavelength range: 400 to 520 nm) will be used during sunny periods of a day. Another canopy with a film that transmits about 79% blue light will be used during overcast periods of the day. The infants will be moved from one canopy to the other as needed during the day with the goal of keeping the blue light irradiance level above 8 μW/cm²/nm.Primary outcomeFS-PT will be as efficacious as CPT in reducing the rate of rise in bilirubin levels. Secondary outcome: The number of infants requiring exchange transfusion under FS-PT will not be more than those under CPT.ConclusionThis novel study offers the prospect of an effective treatment for infants at risk of severe neonatal jaundice and avoidable exchange transfusion in poorly-resourced settings without access to (reliable) CPT in the tropics.Trial registrationClinicalTrials.gov Identifier: NCT01434810.

Project description:BACKGROUND: In many resource-limited settings, the availability of effective phototherapy for jaundiced infants is frequently hampered by lack of, or inadequate resources to acquire and maintain conventional electric-powered phototherapy devices. This study set out to ascertain maternal experience and satisfaction with a novel treatment of infants with significant hyperbilirubinemia using filtered sunlight phototherapy (FSPT) in a tropical setting with irregular access to effective conventional phototherapy. METHODS: A cross-sectional satisfaction survey was conducted among mothers of jaundiced infants treated with FSPT in an inner-city maternity hospital in Lagos, Nigeria from November 2013 to March 2014. Mothers' experience during treatment was elicited with a pretested questionnaire consisting of closed and open-ended items. Satisfaction was rated on a five-point Likert scale. Correlates of overall maternal satisfaction were explored with descriptive and inferential non-parametric statistics. RESULTS: A total of 191 mothers were surveyed, 77 (40%) of whom had no prior knowledge of neonatal jaundice. Maternal satisfaction was highest for quality of nursing care received (mean: 4.72?±?0.55, median: 5[IQR: 5-5]) and lowest for physical state of the test environment (mean: 3.85?±?0.74, median: 4[IQR: 3-4]). The overall rating (mean: 4.17?±?0.58, median: 4[IQR: 4-5]) and the observed effect of FSPT on the babies (mean: 4.34?±?0.58, 4[IQR: 4-5]) were quite satisfactory. FSPT experience was significantly correlated with the adequacy of information received (p?<?0.0005), test environment (p?=?0.002) and the observed effect of FSPT on the child (p?<?0.0005). Almost all mothers (98.4%) indicated willingness to use FSPT in future or recommend it to others, although some (30 or 15.7%) disliked the idea of exposing newborns to sunlight. CONCLUSIONS: Mothers of jaundiced newborns in this population are likely to be satisfied with FSPT where it is inevitable as an alternative to conventional electric-powered phototherapy. Adequate information, good test environment and friendly nursing care must be ensured for satisfactory maternal experience.
