  • Annual result of retinopathy of prematurity screening in Shanghai area

    Objective To investigate the incidence of retinopathy of prematuri ty (ROP) in the area of Shanghai, and to provide the preliminary data for the ev aluation of present criteria for ROP screening. Methods Record s of 289 prematur e infants who had undergone ROP screening from the four NICU in Shanghai between February 2004 and January 2005 were analyzed. Screening criteria included prete rm infants or low birth weight (LBW) infants with BW of 2000g or less. The first examination starts at 4 to 6 weeks chronologic age or 32 weeks post conceptual age. Results In the 289 screened infants, 19 had developed acu te ROP. There we re 3 threshold ROP, 7 prethreshold ROP and 9 developed ROP less than prethreshol d. The incidence of ROP was 6.6%. According to the British recommended guideline s(BWle;1500 g or GAle;31 weeks), only 119 out of 289 needed screening and one ca se of stage 1 ROP was missed; the incidence of ROP was 15.1% (18/119). When lowered sc reening criteria to the American guidelines(BWle;1500g or GAle;28 weeks), t here were only 83 infants needed screening, and we missed 2 stage 1 and 1 prethreshold ROP and the incidence of ROP was 19.3% (16/83). Conclusions The i ncidence of ROP i s 6.6% according to our study. It is lower than other reports and it has somethi ng to do with our present screening guideline. Further epidemiological data are needed to modify the guideline accordingly.

  • The economic evaluation of screening and early diagnosis of primary immunodeficiency diseases: a systematic review

    ObjectiveTo systematically review the economics evaluation studies on the early screening or diagnosis of primary immunodeficiency diseases (PID). MethodsWeb of Science, CRD, PubMed, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect the economics evaluation studies on the early screening or diagnosis of PID from inception to July 1st, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, a descriptive systematic review was performed. ResultsA total of 10 studies focusing on SCID were included. The results showed that under a relatively high threshold, the early screening and diagnosis of SCID were cost-effective, which can reduce severe infections in patients and treatment costs while improving patient’s survival. ConclusionCurrent evidence shows that early diagnosis of PID can reduce costs and improve benefits. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.

  • Diagnostic accuracy of TRECs in newborn screening for severe combined immunodeficiency: a meta-analysis

    ObjectiveTo systematically review the accuracy of T-cell receptor excision circles (TRECs) in screening newborns for severe combined immunodeficiency (SCID). MethodsThe PubMed, EMbase, Cochrane Library, Web of Science, CBM, WanFang Data and CNKI databases were electronically searched to collect the diagnostic accuracy studies related to the objects from inception to October 26, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies using the QUADAS-2 scale. Meta-analysis was performed using Stata 15.0 and Meta-Disc 1.4 software. ResultsA total of 18 studies involving 6 243 718 neonates were included. The results of meta-analysis showed that the pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnosis odds ratio (DOR) were 0.97 (95%CI 0.92 to 0.99), 1.00 (95%CI 1.00 to 1.00), 1447.05 (95%CI 528.49 to 3962.11), 0.13 (95%CI 0.08 to 0.22) and 11698.21 (95%CI 2853.44 to 47958.98), respectively. The area under the summary receiver operating characteristic curve (SROC) was 0.97. ConclusionThe application of TRECs in screening neonatal SCID has high accuracy, which is helpful for early diagnosis of SCID. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.

  • Analysis of the clinical characteristics of retinopathy in multiple premature infants

    ObjectiveTo observe the clinical features of retinopathy of prematurity (ROP) in multiple fetuses.MethodsRetrospective clinical study. From December 2009 to June 2018, 758 premature or low-weight multiple fetuses (multiple fetuses group) and 2363 simultaneous single fetuses (single fetuses group) who were admitted to the Department of Ophthalmology and Neonatal Department of Dongguan People’s Hospital and underwent ROP screening were included in the study. Among the multiple pregnancy group, there were 735 twins and 23 triplets; 441 males and 317 females. The mean gestational age was 32.22±2.14 weeks, and the mean body weight was 1.69±0.43 kg. There were 202 of natural births and 556 of cesarean sections. A total of 750 cases have a history of oxygen. Among the singleton group, 1421 were males and 942 were females. The mean gestational age was 32.06±2.52 weeks, and the mean body weight was 1.70±0.46 kg. There were 1146 of natural births and 1217 of cesarean sections. A total of 2333 cases have a history of oxygen. The detection rate of multiple ROP, gestational age, birth weight, sex composition ratio, mode of birth, time of first ROP diagnosis, and severity of ROP were observed. χ2 test was used to compare the rate between groups, and t test was used to compare the mean between groups.ResultsAmong the multiple pregnancy group, there were 68 cases (8.97%) of ROP. Among them, 64 twins (8.71%, 64/735), 4 triplets (17.39%, 4/23). Among the singleton group, there were 187 cases (7.91%) of ROP. With the increase of fetal number, the detection rate of ROP increased, but there was no significant difference (χ2=3.097, P=0.213). There was no significant difference in the detection rate of ROP between multiple fetuses and single fetuses (χ2=0.855, P=0.355). There was no significant difference in sex ratio (χ2=0.069), mode of production (χ2=1.900), birth weight (t=0.139), gestational age (t=-0.478), and time of first ROP diagnosis (t=0.371) between ROP cases of multiple fetuses and single fetuses (P=0.793, 0.168, 0.889, 0.633, 0.371). There was no significant difference in the constituent ratio of severity of ROP lesions between multiple fetuses and single fetuses (χ2=3.003, P=0.223).ConclusionThere is no significant difference in ROP incidence, gestational age, birth weight, diagnosis time and severity of ROP between multiple fetuses and single fetuses under the same conditions.

  • The incidence of retinopathy of prematurity in Shenzhen during the past ten years

    ObjectiveTo retrospectively analyze incidence and trends of retinopathy of prematurity (ROP) from 2004 to 2013 in Shenzhen. MethodsA total of 9100 preterm children (5401 males, 3699 females) were screened for ROP in Shenzhen from January 2004 to June 2013 using binocular ophthalmoscope or RetCam Ⅱ. First examination was performed from 4-6 weeks after birth. The birth weight was 520-2990 g with an average of (1710±410) g.The gestational age were 24-36 weeks with an average of (31.57±1.99) weeks. The gestational age of 208 children were <28 weeks, 3608 children were 28-32 weeks, 3553 children was 33-34 weeks, 1731 children was >34 weeks. The ocular findings were recorded according to the International Classification of ROP and The Early Treatment for ROP. Only the more aggressive eye of bilateral asymmetrical cases was counted for statistical purpose, and the cases required surgeries were defined as severe cases. The 10 years period was divided into first phase (2004-2008) and second phase (2009-2013). The incidence of ROP and severe ROP of these two phases was compared and statistics was analyzed. ResultsIn the past 10 years, the overall incidence of ROP and sever ROP in Shenzhen was 12.49% and 4.99% in this screen. The children were divided into 4 groups according to the birth weight, the ROP incidences of birth weight <1000 g, 1000-1499 g, 1500-1999 g and ≥2000 g were 62.62%, 28.40%, 11.34% and 3.63% respectively. The severe ROP incidences were 34.95%, 12.21%, 3.73% and 0.49% respectively in these birth weight groups. The children were divided into 4 groups according to gestational weeks, the ROP incidences of gestational age <28 weeks, 28-32 weeks, 33-34 weeks and >34 weeks were 67.31%, 25.27%, 7.22% and 3.87% respectively. Severe ROP incidences were 37.02%, 10.71%, 1.79% and 0.68% in these gestational age groups respectively. ROP and severe ROP incidences were decreased from 14.64% at first phase to 11.47% at second phase, and from 6.52% at first phase to 4.26% second phase respectively, the differences were statistical significant (χ2=26.96, 26.61; P<0.05). ROP and severe ROP incidence in <1000 g birth weight group at second phase were much less than the first phase (χ2=13.676, 5.271; P<0.05). In <28 weeks gestational age group, the ROP incidence was the same in first phase and second phase (χ2=0.843, P>0.05), but the severe ROP incidence at second phase was much less the first phase (χ2=4.757,P<0.05). ConclusionFrom 2004 to 2013, the incidences of ROP and severe ROP have decreased significantly in Shenzhen.
