Official scientific title Effectiveness of Fiberoptic Phototherapy Compared to Conventional Phototherapy in Treating Hyperbilirubinemia Amongst Term Neonates Receiving Care at Kilimanjaro Christian Medical Centre
Brief summary describing the background and objectives of the trial Globally an estimated 50% of term newborns develop hyperbilirubinemia (which may manifest as jaundice), typically 2-4 days after birth and about 25% of these babies will require phototherapy to avoid the effect of high serum unconjugated bilirubinaemia which can lead to Bilirubin-Induced Neurologic Dysfunction (BIND) which occurs when bilirubin crosses the blood-brain barrier and binds to brain tissue resulting in brain injury if not treated appropriately in a timely fashion. (Hülya, Eren and Ahmet, 2008; Jardine and Woodgate, 2015; Maisels, 2017) Three interventions are used to reduce total serum bilirubin (TSB) levels for infants with or at-risk for developing hyperbilirubinemia, which are promotion of enteral feeds, phototherapy, and exchange transfusion. Phototherapy is now the preferred method of treatment for neonatal hyperbilirubinemia by virtue of its non-invasive nature and its safety. Phototherapy refers to the use of light of specific wavelengths and doses to convert lipophilic bilirubin molecules in the body into water soluble isomers that can be excreted by the body to reduce TSB. Currently there are several forms of phototherapy: conventional, fiberoptic and LED used in the treatment of hyperbilirubinaemia (Al-Alaiyan, 1996). Conventional and fiberoptic phototherapy has been proven to be equally effective in treatment of hyperbilirubinaemia among preterm neonates (Heijden, 1998). However, a Cochrane review reported the efficacy of fiberoptic phototherapy in a number of different clinical situations and patient populations, they found that fiberoptic phototherapy was less effective than conventional phototherapy at lowering serum bilirubin (SBR) in term neonates (Mills and Tudehope, 2009). These findings were attributed to the low irradiance and the surface area illuminated by the mat of the fiberoptic phototherapy units used in previous studies (Costello et al., 1995; Heijden, 1998). Therefore, this study aims to compare the fiberoptic phototherapy unit with a larger illuminated area and high irradiance to conventional phototherapy with regard to bilirubin reduction rate, side effects and duration of treatment among term neonates with hyperbilirubinemia. Improved effectiveness with fiberoptic phototherapy might mitigate the disadvantages of conventional phototherapy, create greater mother neonate bonding and encourage breastfeeding. Findings will assist to minimize hospital stay which has an impact on workload in the NCU and economic burden to the family and hospital.

Experimental Group Fiberoptic phototherapy The BiliBlu LED fiberoptic phototherapy unit has a body surface area of 25cm x 40cm,with a constant setting of 34 microW/cm2/nm light irradiance. This was wrapped around the newborn Once a newborn’s total serum bilirubin levels reached the threshold phototherapy level on the AAP phototherapy nomogram, phototherapy was initiated.Serum bilirubin reduction rate was measured to monitor response to treatment, this was assessed as the decline in the TSB levels for the duration of exposure to phototherapy, expressed as a percentage of decline per hour. This was monitored through daily (every 24 hours of exposure) sampling of blood for total serum bilirubin. Treatment failure was defined as the need for additional phototherapy units (‘double phototherapy ‘) determined by serial serum bilirubin response while on phototherapy, of which a rise in serum bilirubin level more than 9 μmol /L per hour after phototherapy initiation was an indicator for double phototherapy. Phototherapy was stopped when serum bilirubin levels were <50micromol/l on the AAP nomogram, and treatment duration was then assessed as the duration of time exposure to phototherapy in hours. A parallel randomized control trial to test three treatment groups was conducted in the neonatal care unit (NCU) at the Kilimanjaro Christian Medical Centre (KCMC) in Northern Tanzania from January 2019 to May 2019. The NCU has a bed capacity of 62 babies, with an average of 6 enrolled and registered nurses caring for neonates per shift. The babies are nursed in locally made heated cots which use incandescent bulbs to heat up the cot. In our neonatal care unit, phototherapy is the only treatment modality used for unconjugated hyperbilirubinaemia. 65 term neonates (>37 weeks of gestation), less than 7 days of age, admitted with jaundice, were identified by clinicians working in the neonatal unit and screened for eligibility. We included those with hemolytic and non-hemolytic unconjugated hyperbilirubinemia with a total bilirubin level that has reached phototherapy threshold values as per the American Academy of Pediatrics (AAP) nomogram, which is a validated tool used for making decision regarding phototherapy in infants with unconjugated hyperbilirubinemia. Newborns receiving phenobarbitone; newborns with bilirubin levels that have reached exchange transfusion levels on the AAP nomogram; newborns with conjugated hyperbilirubinaemia; newborns who have already received phototherapy prior to enrollment and those whose parents refused to consent were excluded from the study. The study proposal was reviewed and approved by the ethics committee of the Kilimanjaro Christian Medical University College. Once a newborn’s total serum bilirubin levels reached the threshold phototherapy level on the AAP phototherapy nomogram, we offered parents or guardians verbal and written information on phototherapy, including all of the following: why phototherapy is being considered, why phototherapy may be needed to treat hyperbilirubinaemia, the possible side effects of phototherapy, the need for eye protection and routine eye care, reassurance that short breaks for feeding, nappy cha 13
Control Group Blue light conventional phototherapy The blue light PT unit “Olympic Bili-Lit model 66”, consists of four blue fluorescent bulbs placed 20 cm above the newborn with a constant irradiance of 27 µW/cm2/nm. Eye pads were used to prevent damage to the retina. Once a newborn’s total serum bilirubin levels reached the threshold phototherapy level on the AAP phototherapy nomogram, phototherapy was initiated.Serum bilirubin reduction rate was measured to monitor response to treatment, this was assessed as the decline in the TSB levels for the duration of exposure to phototherapy, expressed as a percentage of decline per hour.

Detailed explanation of what will happen during phototherapy was also provided: the newborn will be nursed in a supine and prone position unless other clinical conditions prevent this, treatment will be applied to the maximum area of skin, newborn's temperature will be monitored, and the hydration of the newborn will be assessed by daily weighing. Formal consent was obtained from the parent of the study participant. We observed confidentiality of the names of the study participants by using code numbers. We included 41 term neonates who met the inclusion criteria. In order to obtain our sample size, we used the 34µmol/L effect size in the three arms, with a level of significance of 5%, power of 85% . The minimal sample size in addition to non-response rate of 20% was 39. A questionnaire was used to collect demographic data such as sex, gestation age at birth (determined according to the maternal history and Ballard’s scoring system), mode of delivery, birth weight in kilograms, residents, age at enrollment in days, and type of feeding mode. Participants were randomized , then allocated to intervention groups by the research assistants. Simple randomization was performed by drawing a paper from a container containing 45 folded papers: 15 marked ‘FB’ (Fiberoptic BiliBlanket), 15 marked ‘B’ (Bluelight PT) and 15 marked ‘W’ (White light PT). Thus, the choice of the intervention was not according to the preference of the research assistant, nor were they informed about the total serum bilirubin levels of the newborns at the study entry, in order to prevent bias. This was an open label trial whereby both the parent of the participants and the researchers knew which intervention the newborn was receiving. Before phototherapy initiation, a clinical assessment was done on the newborn, which includes physical examination by a certified clinician; body weighing of the naked newborn 13 Active-Treatment of Control Group

Yes In our study, phototherapy was effective in decreasing bilirubin levels in all three groups. The response was greater in the blue light conventional phototherapy (0.84%/h), followed by fiberoptic phototherapy (0.74%/h), whereas the white light conventional phototherapy (0.29%/h) had the lowest response in lowering serum bilirubin levels. The effectiveness of fiberoptic PT and blue light conventional PT were comparable in terms of bilirubin reduction rate and treatment duration, whereas fiberoptic phototherapy was more effective than white light conventional PT, with a significantly lower bilirubin reduction rate and treatment duration. No side effects were reported in the fiberoptic PT group, while both conventional PT groups reported loose stool. A transient erythematous skin rash was noted with blue light conventional PT. 29/03/2020 30/04/2020
