Study 281 – First report from the US PRIORITY Study 

The PRIORITY study collected self-reported cases of Covid-19 in pregnancy. In this report they describe the outcomes of 179 infants born to mothers who had tested positive and 84 who tested negative. 82% of the former group and 63% of the latter had symptoms (click here or ciaa1411). 44 babies were admitted to NICU, and two were infected. Although not explicitly stated there appear to have been no stillbirths or neonatal deaths. Births occurred at over 100 hospitals across the US so it is likely that many will have been included in other US reports.

A woman with Covid-19 presented to New York City Health and Hospitals/Lincoln on March 12, 2020 (click here or 9795-IN PRESS-52450-5-10-20200908). She had mild disease, was treated as an outpatient and recovered. She was delivered by Caesarean at 37 weeks and the baby was not infected. The authors claim this was the first case of Covid-19 in pregnancy in the US. They may be correct.

Study 271 – 86 “extra” maternal deaths during pandemic in Mexico

These authors used publicly available goverment statisitics (click here) to estimate the excess maternal deaths from Covid-19 in Mexico in 2020 (click here or Excess_Maternal_Deaths_Associated_With_Coronavirus.97254). The predicted maternal mortality ratio was 29.5 per 100,000 live births, and so far in 2020 the actual ratio is 42.4. The excess was entirely confined to respiratory disease. Overall 86 “extra” deaths have ocurred. In comparison the 168 deaths officially reported as due to respiratory disease are made up of 109 deaths due to confirmed COVID-19, 34 for which COVID-19 needs to be confirmed, and 25 due to other respiratory diseases.

Of 66 women with Covid-19 treated between March 1 to Sep 1, 2020, four were admitted to ICU but none required ventilation (click here or taaa158). Two women aborted, 43 delivered, and 21 pregnancies are ongoing. No baby outcomes are reported directly, although one baby tested positive. No women in the series died. However in the discusssion section it is mentioned that in February 2020, a 22-year-old pregnant woman with COVID-19 at 37 weeks had died in the same hospital. It is not clear if she had been included in studies 23, 66 or 67. The women were cared for in Arash Women’s Hospital, which has also reported a set of triplets of which one was infected with SARS-CoV-2 and survived, and the other two who were negative died, (case 5 in study 250).

Of 675 pregnant women admitted for delivery and tested for SARS-CoV-2, 70 were positive, of whom 55 were asymptomatic on presentation (click here or 1471-0528.16403). Three mothers were hypoxic, one was admitted to ITU but none required ventilation. No mothers died. There was one stillbirth to a mother with asymptomatic Covid-19 and other pathology. 73 babies were born, 71 were tested and all were negative. The three hospitals, were Weill Cornell Medical Center, Queens, and Lower Manhattan Hospital. The cases may therefore also have been included in studies 160, 216 and 230. However, they were probably not included in the other NY Presbyterian series namely studies 14, 27, 41, 95, 96 and 136.

Study 233 – case report from Morocco

A woman contracted Covid-19 at 31 weeks gestation, required oxygen therapy and went into premature labour. A Caesarean was performed for fetal distress (click here or 8852816). The mother recovered. The baby tested negative but had severe birth asphyxia and died age 5 days. The mother was cared for at University Hospital of Mohammed VI, Marrakech, which has not previously reported cases. This is the first report from Morocco.

Study 232 – 44 cases from US

Of 44 pregnant or recently postpartum women with COVID-19, 5 had severe disease and 2 required ventilation (click here or ijgo.13333). All mothers survived. Of 11 babies born, 9 tested negative and 2 declined testing. All survived. 31 pregnancies are ongoing. The majority of patients belonged to racial [sic] or ethnic minority groups. From author affiliations the unnamed hospital was probably Brigham and Women’s Hospital, Boston. Some cases may therefore have been reported in study 231, but probably differ from those in studies 129 & 142. Citation: Onwuzurike, C., Diouf, K., Meadows, A.R. and Nour, N.M.

Study 231 – 19 placentas from USA

2/19 placentas of affected pregnancies tested positive for SARS-CoV-2 by in-situ hybrization (click here or s41379-020-0639-4). There were no specific pathologic features compared with 262 control placentas. One fetus was stillborn at 22 weeks and not tested. There were two sets of twins. All liveborn babies survived, and only one tested positive. From the case codes in Table 2 it appears that 10 pregnancies had been cared for at Massachusetts General Hospital, 4 at Brigham and Women’s Hospital & 5 at Beth Israel Deaconess Medical Center, Boston. Some have therefore probably been reported in studies 129 & 142Citation: Hecht, J.L., Quade, B., Deshpande, V. et al. SARS-CoV-2 can infect the placenta and is not associated with specific placental histopathology: a series of 19 placentas from COVID-19-positive mothers. Mod Pathol (2020). https://doi.org/10.1038/s41379-020-0639-4

Study 230 – Placental features of 74 cases from USA

2/53 placentas from affected pregnancies contained a SARS-CoV-2 viral signal by in-situ hybridization (click here or Zhang, Placenta, AJOGMFM). One baby tested positive, the other negative. Both were asymptomatic. There were no specific histological differences between 74 placentas from SARS-CoV-2 positive pregnancies and 290 controls. The authors are affiliated with the New York Presbyterian, Brooklyn Methodist, Weill Cornell group of hospitals so the clinical aspects of the cases have probably been reported before.  Citation: Zhang P, Heyman T, Salafia C, Dygulska B, Lederman S, Detection of SARS-CoV-2 in placentas with pathology and vertical transmission, American Journal of Obstetrics & Gynecology MFM (2020), doi:  https://doi.org/10.1016/j.ajogmf.2020.100197.

8 August update – studies 225 to 229 added

Study 229 – Some assisted reproduction pregnancies during the pandemic in France.

The authors report 88, or possibly 104, women (numbers are unclear) who conceived by assisted reproduction between December 2019 & March 2020, and were still pregnant after the first reported case of Covid-19 in France on 12th February. Ten had symptoms related to Covid-19, none severe or requiring intensive care (click here or PIIS0301211520304929). Five of the ten were tested and two were positive. 15 women miscarried although their Covid-19 status was not reported. From author affiliations the unnamed centre was probably the Reproductive Biology UnitAntoine Béclère Hospital, Clamart. These cases may therefore feature in studies 150, 157, 184 & 217. The pregnancies were unlikely to have been sufficiently far advanced to have featured in studies 48 & 187.

Study 228 – case report from USA

A pregnant woman contracted severe Covid-19 requiring ventilation at 32 weeks (click here or Ching Case Rep RespMed). She was delivered by Caesarean section for suspected placenta praevia and recovered. The baby required intubation and ventilation for 48 hours but tested negative. The ultimate baby outcome is not reported. The hospital is unnamed but the authors’ affiliation with San Joaquin Critical Care Medical Group, suggests that it was San Joaquin General Hospital in Stockton, California which has not previously reported cases.

Study 227 – case report from USA

A woman with mild Covid-19 gave birth to a male infant vaginally at term (click here or HSU jmv.26386). She recovered. The baby breast fed, tested negative and was fine. The virus was demonstrated in the placenta by immuno-histochemistry using a  SARS-CoV-2 nucleocapsid-specific monoclonal antibody. Mother and baby were cared for at University of Missouri Women and Children’s Hospital Columbia, Missouri, which has not previously reported cases. The clinical details of case 69 differ.

Study 226 – 3 cases treated with remdesivir from USA

Three pregnant women with Covid-19 were treated with remdesivir outside a clinical trial (click here or PIIS0002937820308292). One developed “transaminitis” – I think the authors mean raised liver transaminase. The pre-print is missing a table – which the authors attributed to the remdesivir. That woman later developed intrahepatic cholestasis of pregnancy and delivered normally. The other pregnancies are ongoing. The acknowledgements suggest that the unnamed hospital is Lucile Packard Children’s Hospital at Stanford, California. Although one author is shared with study 115 from another unnamed Stanford hospital, the clinical details differ. These cases have probably not previously been reported.

Study 225 – over 600 cases (412 births) in India

Nair hospital, Mumbai, a dedicated Covid-19 facility, has cared for over 600 pregnant women with the disease (click here or ijgo.13338). There have been 412 births including seven pairs of twins and one set of triplets. No mothers died of Covid-19 directly, although four died of other causes. No baby outcomes reported. The first two cases had originally been cared for elsewhere, and also previously denied admission at four private hospitals, the latter a feature of news reports from India (click here). Two health care workers contracted COVID-19. Nair Hospital has not previously reported cases. The case reported in study 58 was from New Delhi.

Study 213 – 89 cases from Brazil

Of 89 women with Covid-19 cared for in a single institution between March 12 & May 25, 2020, the details of five who experienced a fetal death are reported (click here or 1-s2.0-S2214911220300734-main). No details of the other cases, and no explicit maternal outcomes are reported, but enough details are given for it to be implied that the mothers survived. From author affiliations the unnamed hospital is probably Hospital e Maternidade Santa Joana, São Paulo. Apart from study 194 which was from a different city, all previous reports of Covid-19 in pregnancy from Brazil (studies 66, 138, 182 & 201) have been of maternal deaths. These cases have therefore probably not previously been reported.

Study 201 – 20 maternal deaths from Brazil

Twenty COVID-19 related maternal deaths were identified from the Brazilian Ministry of Health surveillance system (click here or Takemoto Maternal mortality and COVID 19). Ten were in the Northeast region, and nine in the Southeast (5 in São Paulo). They probably overlap with those in studies 138, 182 & 194Citation: Maira L. S. Takemoto , Mariane O. Menezes , Carla B.

Study 200 – 23 cases from UK

Of 23 pregnant women with COVID-19, four were admitted to ITU and one died from basilar artery thrombosis, pulmonary embolism, and diabetic ketoacidosis (click here or Antoun EJOG 1-s2.0-S0301211520304486-main). 20 babies were delivered, incl. one set of twins. All survived. Seven babies were tested for SARS-CoV-2 and all were negative. The hospital is unnamed but from its size and author affiliations is likely to be Birmingham Women’s Hospital which has not previously reported cases. However, they will have been included in the UKOSS report study 92. The clinical details of the maternal death suggest this is the same patient as reported in study 107 as having been delivered at Birmingham Heartlands Hospital.

Study 193 – Case report from Belgium

A pregnant woman with twins developed mild Covid-19 at 22 weeks gestation (click here or Pulinx 10096_2020_Article_3964). She was nursed at home, but at 24 weeks went into spontaneous labour. One twin was stillborn and the other died soon after birth. Amniotic fluid and placental tissue tested positive for SARS-CoV-2.

Study 191 – 27 cases from Spain

This preprint reports 27 pregnant women with COVID-19 of whom seven developed some features of HELLP syndrome (click here or 2020.07.10.20133801v1.full). The details are difficult to interpret but I think 12 delivered, 5 by Caesarean, and no mothers or babies died. The patients were cared for in two unnamed hospitals which from author affiliations were probably Hospital de la Santa Creu i Sant Pau and Hospital Sant Joan de Deu, both in Barcelona. These hospitals have not previously reported cases under their own names. However, the patients may have been included in the Spanish Covi-Preg registry study 151.

Study 188 – Four, possibly five, cases from Italy

Four pregnant women with Covid-19 and a further woman who had possible pneumonia one day after delivering twins and two months later had SARS-CoV-2 IgG antibodies, are reported (click here or 10.1080@14767058.2020.1791817) All mothers and babies survived although one of the four definite Covid-19 mothers developed Guillain-Barré syndrome and remains in hospital. All patients were cared for Bolognini Hospital which is a “spoke center” for COVID 19 in pregnancy in Seriate, Bergamo in Lombardy. It is thus likely that they were included in studies 32, 64 & 117.

Study 187 – Case report of neonatal infection from France

A woman contracted Covid-19 at 35 weeks, required Caesarean for fetal distress, and recovered with supportive treatment (click here or s41467-020-17436-6). The baby was initially well but developed neurological symptoms on day 3. Maternal nasopharynx (NP), blood, placental, vaginal and amniotic samples were all positive for SARS-CoV-2. Baby blood and rectal samples, as well as NP samples on days 1, 3 and 18, were also positive. The baby recovered with supportive treatment. From author affiliations the hospital was Antoine Béclère, Paris. Although not cited, this is case two in study 48. The papers share two authors, Alexandra J Vivanti & Alexandra Benachi, from the same hospital, and all reported maternal and baby characteristics, as well as all the mother’s blood values on the day of birth, are identical.

Study 184 – 100 cases from France

One hundred pregnant women with Covid-19 were treated in four Paris hospitals between March 12 & April 13, 2020 (click here). Ten were admitted to ICU of whom 9 required intubation. There were no stillbirths or miscarriages, but one neonatal death due to prematurity. All neonates were tested for SARS-CoV-2. One was positive but did not show signs of respiratory illness. The hospitals were Antoine Béclère, Clamart; Bicêtre Hospital, Le Kremlin Bicêtre; Louis-Mourier, Colombes; and Centre Hospitalier Sud Francilien, Evry. They therefore include one of the cases in study 48, are included in study 150 and probably also overlap with those in study 157.

Study 161 – 54 cases from France

Of 54 pregnant women with confirmed (n=38) or suspected (n=16) COVID-19 in pregnancy treated at Strasbourg University Hospital from March 1 to April 3, there was one miscarriage, 21 live births (12 vaginal, 9 cesarean), and 32 ongoing pregnancies (click here or PIIS0002937820306396). Five women were admitted to ICU, three required mechanical ventilation and one ECMO. No mothers died, although at the time of writing the woman on ECMO remained on it.

Study 160 – 241 cases from USA

Of 241 pregnant women with laboratory-confirmed SARSCoV-2 infection who gave birth between March 13 & April 12, there were 245 live births to 241 women (6 sets of twins), & 2 stillbirths (click here or Characteristics_and_Outcomes_of_241_Births_to.97310). 17 women were admitted to ITU and 9 intubated. No mothers died, although one woman remained intubated at time of writing. 27% of neonates were admitted to NICU. Of liveborns with SARS-CoV-2 test results 236/230 tested negative. No further neonatal outcomes reported. The five hospitals were “Montefiore Medical Center; Mount Sinai Health System, including Mount Sinai Hospital and Mount Sinai West; its affiliate, NYC Health and Hospitals- Elmhurst Hospital; NY-Presbyterian Hospital- Columbia University; and NY University Langone Health, including NYU Langone Hospitals, Manhattan campus, and NYU Langone Hospitals-Brooklyn”. These cases therefore likely overlap with studies 14, 27, 41, 49, 83, 85, 86, 95, 95, 119, 135, 136, & 152. They probably do not overlap with women in studies 61, 113, 118, 122 & 134, which included women cared for in different centres. Women in Study 99 are unclear.

Study 141 – 201 women from the Netherlands Covid in pregnancy registry

The 22nd May update of NethOSS (click here), accessed 4 June 2020, contains the following. 7/176 women with brief additional details were admitted to intensive care. One mother died after prolonged admission and intubation as a result of pulmonary infection with multiple pulmonary emboli. 49 women have given birth, 16 by Caesarean. 124 pregnancies are ongoing. No baby has died. No babies were infected. Citation: See Studies 42, 46 & 120. Available here. Accessed 4 June 2020.

Study 140 – 42 cases from Spain

Forty two pregnant women with Covid-19 between March 13 & April 10 (click here or 1471-0528.16339). Eight required admission to ICU of whom 6 developed some features of pre-eclampsia, 4 requiring Caesarean, one of which was due to HELLP syndrome. No maternal or baby outcomes are reported but it is implied “after recovery from severe pneumonia, hypertensive therapy was no longer required in all cases” that all women recovered. The “tertiary care” hospital is not named but from author affiliations is likely to be Hospital Universitari Vall d’Hebron, Universitat Autònoma de Barcelona. If so, these cases have not been previously reported.

Study 139 – 13 cases in USA

Twelve women with Covid-19 were detected through targeted testing, and one by universal screening (click here or ciaa675). No separate clinical details given for the SARS-Cov2 positive women.  Patients were treated at the University of Washington Montlake Labor and Delivery Unit and Northwest Birth Center. They therefore likely overlap with Study 102.

A 37-year-old woman tested positive for SARS-Cov2 and presented two days later with an ectopic pregnancy (click here or Ectopic_Pregnancy_During_Coronavirus_Disease_2019.97340). The authors discuss treatment options but give no further clinical details. Although the report is ambiguous, it is conventional in educational medical reports to present real cases unless stated otherwise. From author affiliations the patient was likely cared for in South Dakota or Texas. Citation: Hansen, Keith A; Stovall, Dale W.

Study 133 – 3 cases identified by screening in Italy

By screening 533 women admitted for delivery for SARS-CoV2 between March 26th & April 1st in North Tuscany and Liguria, these authors identified 3 positives, who all gave birth without clinical problems (click here or PIIS0002937820305421). The women birthed in all the 6 hospitals of Azienda USL “Toscana Nord Ovest” (Tuscany), and Gaslini Children’s Hospital (Genoa, Liguria). They have therefore probably not previously been reported.

May 6th update – study 79 (HT Shakila Thangaratinam) & studies 80 & 81 added.

Study 81 – Case report from China

A 31 year old woman developed Covid-19 at 35 weeks gestation (click here, or ijgo.13189). The mother’s condition deteriorated rapidly, requiring ventilation, and later ECMO. The baby was delivered by emergency caesarean but died within two hours. The mother survived. This is the second pregnant woman requiring ECMO reported from China. Zhongshan People’s Hospital disambiguates as grid.476868.3 and no patients from Zhongshan have previously been reported, not in Study 3, nor in studies 55 or 57. This case is therefore likely original. Citation: Li J, Wang Y, Zeng Y, Song T, Pan X, Jia M, He F, Hou L, Li B, He S, Chen D. Critically ill pregnant patient with COVID-19 and neonatal death within two hours of birth. Int J Gynaecol Obstet. 2020 May 5. doi: 10.1002/ijgo.13189.

Revised comment 7 May. The city of Zhongshan is in the province of Guangdong. Study 3, which initially mentioned “patient 6”, a 31 year old woman at 34 weeks on ECMO, whose baby had died, included one patient from Guangdong. Study 57 described a 32-year-old woman at 35 weeks from Zhongshan, Guangdong whose baby had died soon after birth. At the time of the report that woman had been weaned off ECMO but remained an inpatient. Despite the minor inconsistencies in maternal and gestational ages, it is likely that all three reports refer to the same woman. If so there has only been one pregnant woman with Covid-19, treated with ECMO, and reported from China. She survived.

Study 70 – Maternal death from Iran

A 22-year-old developed Covid-19 at 32 (or possibly 30) weeks gestation, and was treated at Imam Khomeini Hospital of Mazandaran University, Sari (click here or ZAMANIYAN M_Iran_Prenatal diagnosis). She was delivered by Caesarean section, but on day 10 required ventilation, and died on day 15. The first baby swabs were negative, but amniotic fluid and later baby swabs were positive. Apart from developing a fever the baby did well. The clinical details suggest that she was not included in Study 67.

Study 57. 116 cases from 25 hospitals in China

This preprint from Am J Obstet Gynecol (click here) includes 116 mothers with Covid-19 (65 lab confirmed, 51 clinically diagnosed), of whom 8 had severe disease. None died. 99 mothers had delivered 100 babies (one set of twins) of whom one died. This paper claims to be an “an expanded series that have included 33 published cases.16,18-20”. Their reference 16 is our Study 1, ref 18 is our Study 38 and ref 19 is our Study 6a.  Their reference 20 is as follows:  “Lei D, Wang C, Li C, et al. Clinical characteristics of COVID-19 in pregnancy: analysis of nine cases. Chin J Perinat Med 2020,23:doi: 10.3760/cma.j.cn113903-20200216-00117.” Although cited in a number of reviews we have so far been unable to find the original source. Update 18 December – see Study 511

The patients were collected from 25 hospitals within and outside Hubei province, between January 20 and March 24, 2020. Three recruiting hospitals, all from Wuhan, listed in the supplementary material, overlap with those in study 55 (appendix table s1). These are Zhongnan Hospital of Wuhan univerisity, the Central Hospital of Wuhan, and Tongi Hospital, all multiple reporters of Covid-19 in pregnancy. Thus it is likely that, in addition to the studies cited, this series overlaps considerably with Study 55. Not added to running totals. The patient requiring ECMO came from Zhongshan, Guangdong. She is probably the same woman reported as treated with ECMO from the city in Study 3. She survived.

16 April update. Studies 44 & 45 added. HT @Belinda_J_Lowe for study 45. We’ve also done some housekeeping today. Study 13 probably overlaps with study 1, so S13 has been removed from running totals. Study 3 includes 13 patients from multiple centres, both in and outside Hubei province, who may overlap with other studies. 12 mothers (3 undelivered) and 9 babies therefore removed from the running total. Only S3, case 6, woman on ECMO & baby stillborn & preterm, does not appear to have been reported elsewhere, so remains in the running totals.

Study 43. A maternal death from Covid-19 in Iran

25 June update. This paper has been withdrawn because the case, as we had suspected, had also been included in Study 67. Study 67 had been submitted first, albeit to another journal, so the authors judged that it had priority. Details on Retraction Watch (click here)

A 27 year old woman was transferred to Vali-e-asr Hospital at 30 weeks gestation (click here or Karami Travel med Apr 11 2020) with severe respiratory failure. She required intubation and ventilation. A few hours later she delivered a stillborn baby vaginally, and a few hours after that she died. Post-mortem on the mother confirmed SARS-Cov-2 in the lungs. No further details are given about the baby.  Vali-e-asr Hospital does not appear on Grid.ac but is part of Zanjan University of Medical Sciences. grid.469309.1.

However the series probably includes the 16 cases also reported from Remnin in Chinese (study 6a), which included the same number, three, preterm patients, all also delivered by Caesarean. They may also overlap with study 10; both studies mention two doctors delivered by Caesarean in Renmin. The obstetrican on study 36, Bi-heng Cheng, is shared with study 6a. We have therefore not included these cases in the running total.

Study 35. Four neonates with Covid-19 from China

Four infected neonates (age less than 1 month) all born by Caesarean section (click here). They were identified by searching the national database of 81,026 laboratory-confirmed cases up to March 13 using the same methods as in a study of infants age 1 month to one year reported in JAMA (click here but not listed in this blog post). It seems likely that they overlap with the three infected neonates reported earlier in JAMA (study 12), the case report in Clinical Infectious Diseases (study 11) or the infected neonate reported in Lancet Inf Dis (study 15). We have therefore not included them in the running totals. Citation: Zhi-Jiang Zhang, Xue-Jie Yu, Tao Fu, Yu Liu, Yan Jiang, Bing Xiang Yang, Yongyi Bi.

Study 34. Case report of uninfected baby from China

Abstract (click here). Full text (here). A 25 year old woman with Covid-19 at 35 weeks recovered and had a normal vaginal birth of a 3070g boy at 38w + 4d. The baby had no signs of past or present infection with SARS-COV-2. The birth occurred at YouAn Hospital, Capital Medical University, Beijing, which has not previously reported cases in pregnancy, but the mother had been transferred from an unnamed hospital in Wuhan. Nevertheless we have included this as a non-duplicated case in summary totals. Citation: Xiali Xiong, Hong Wei, Zhihong Zhang, Jing Chang, Xiaopeng Ma, Xiang Gao, Qiang Chen, Qiumei Pang.

Study 33. US Centres for Disease Control reports 143 pregnant women

Preliminary data on lab-confirmed COVID-19 reported to CDC Feb 12–March 28, 2020. Of 7,162 cases, 143 were pregnant. Of these 72 stayed home, 31 hospitalised (non ICU), 4 entered ICU, and  36 had unknown hospitalisation status. “[…] for […] pregnancy, few severe outcomes were reported […].” Many probably reported elsewhere, so not added to running totals.

Study 32. 42 women from Italy

This pre-print Ferrazzi Lombardy ijgo.13162 cites a paper in press describing 42 pregnant women from Lombardy, Italy who had Covid-19 and delivered, 18 by Caesarean, and 24 vaginally. Two were spontaneously preterm. Seven women required CPAP or were admitted to ICU, but all “eventually did well”. No baby details are given. This is the first scientific report from Italy.

Study 30. 16 women with Covid-19 pneumonia from Hubei province, China

Sixteen pregnant women with confirmed COVID-19 pneumonia, and 18 with pneumonia on chest imaging who tested negative, were compared with two groups of control pregnancies (click here or ciaa352). The comparative design is similar to study 6a which, apart from an English abstract, has only been published in Chinese. However the hospital and authors differ, so I’m confident there is no overlap.

Study 29. ICNARC report 4 April 2020

This report ICNARC COVID-19 report 2020-04-04.pdf  or click here, from the UK Intensive Care National Audit & Research Centre (ICNARC) mentions two currently, and six recently (<6 weeks) pregnant women with Covid-19 who were also critically ill. One of the currently pregnant, and two of the recently pregnant women, were receiving advanced respiratory support. Excluded from running totals.

Study 28. Seven cases from New Jersey USA

Pre-print from Am J Obstet Gynecol MFM 1-s2.0-S2589933320300434-main, or click here, of two pregnant women with Covid-19 who developed cardiomyopathy. Report also mentions five other pregnant women with Covid-19 in Newark Beth Israel Medical Center.  Details are only given for the two women with cardiomyopathy, and no baby details are given.

6 April update. No new scientific reports today. But obstetricians & midwives will enjoy reading the first newspaper report of a Covid-19 pregnancy and birth in France. Case 10 here. Better written and more detailed than many scientific reports.

5 April update. Study 26 added. The first report of puerperal Covid-19. Not added to running totals.

Study 26. The first case report of puerperal COVID-19, China

This baby developed COVID-19 symptoms at age 10 days and was admitted to Wuhan Children’s Hospital age 17 days on February 5, 2020.  Click here for the article in Chinese. What follows is based on Google translate. Both parents are reported to have had Covid-19 symptoms from three days before admission, i. e. day 14 after birth. This is therefore not a case of COVID infection in pregnancy or at birth, and therefore excluded from the running totals. However, the mother had puerperal Covid-19 and is, I believe, the first such case reported. The baby recovered and by implication, albeit not stated explicitly, so did the parents. The first author Zeng Lingkong shares a name with the first author of the series of 33 neonatal cases reported in JAMA Paediatrics, Study 8., but this is clearly not one of the three infected babies reported in that paper. Citation: Zeng Lingkong, Tao Xuwei, Yuan Wenhao, et al. The first neonatal coronavirus pneumonia in China [J]. Chinese Journal of Pediatrics, 2020,58 (04): 279-280.

In an investigation of 147 pregnant women (64 confirmed, 82 suspected and 1 asymptomatic), 8% had severe disease and 1% were critical.” Neither raw numbers, a citation, nor any further details are given. Assuming the percentages are of all 147, this would imply 12 women with severe disease, and one or two who were critical. In view of the high possibility of double counting – cases notified to the WHO team are likely to have also got reported elsewhere – I’ve left these out of the running total.

3 April update Studies 23 & 24 added. Study 23 is judged unreliable for reasons given below, and study 24 included no pregnancies. Neither have been included in the running totals.

Study 24. No SARS-COV-2 in vaginas of non-pregnant women with severe Covid-19

Although not a study of pregnancy, this report of ten women with confirmed severe COVID-19 pneumonia in Tongji Zhongfa Hospital, Wuhan, China (click here or ciaa375) is reassuring for vaginal birth. None were positive for SARS-CoV-2 by RT-PCR assay in vaginal fluid. Citation: Lin Qiu, Xia Liu, Meng Xiao, Jing Xie, Wei Cao, Zhengyin Liu, Abraham Morse, Yuhua Xie, Taisheng Li, Lan Zhu.

Study 23. Three cases from Iran

This review (click here, full text here) from researchers in both Tehran and Shiraz, includes a report of the births of three infants from infected mothers, apparently not previously reported. The authors’ source was this Iranian ministry website (click here). All three babies were uninfected and survived, but two of the three mothers developed acute respiratory distress syndrome (ARDS) after delivery and died; presumably related to their Covid-19 infection.

Comment by Jim. Although these cases are reported in a scientific journal, the source is a website. The authors do not claim to have treated either the women nor the babies. The women are said to have delivered in Mazandaran and Zanjan provinces. None of the authors give these provinces as their address.  A google translation of the link provided reveals a report of a single case of a woman with COVID-19 who delivered at 36 weeks in Babol. Mother and baby doing well. Again none of the article authors came from Babol. It seems likely that the source of these three cases is the website alone. We have therefore excluded them from our running totals.

30th March update

Study 17. Five from China

Two Caesarean and three vaginal births delivered in the Maternal and Child Hospital of Hubei Province, Tongji Medical College grid.412793.a (click here). Or siyu chen.  All mothers recovered. All babies well. According to Wikipaedia the MCH of HP is the 10th clinical college/hospital associated with Tongji Medical College. It is distinct from both Union hospital and Tongji hospital. These five births are therefore additional to those in the various Union Hospital reports, and to those in study 15. Citation: Chen S, Liao E, Shao Y.

Study 16. Three non-cases from Shenzhen 2nd People’s Hospital.

Shenzen, a city of 13 million had had 420 confirmed cases of Covid-19, the second highest number outside Hubei, up to March 11th. Despite an annual birth rate in the city of 188,000, the 2nd People’s Hospital saw no COVID-19 infected pregnant women. Instead they report three suspected cases who, after barrier nursing, and in one case surgery for an ectopic pregnancy, were later confirmed negative.

29th March – 3rd update

Study 15. Seven cases from China

These seven cases (click here) delivered at Tongji Hospital, Tongji Medical College grid.412793.a, Huazhong University of Science and Technology, Wuhan, between Jan 1 and Feb 8, 2020. All mothers had mild Covid-19 disease and all were delivered around term by Caesarean section. One baby (Patient 1) tested positive for Covid-19 by throat PCR at 36 hours and was transferred to Wuhan Children’s hospital. His mother’s age, gravidity, parity, lack of direct contact with Hunan seafood market and history of hypothyroidism all suggest this is the same mother/infant dyad as in report 11. Note however the reported birthweights differ 3250g v 3205g. No babies had any clinical symptoms and all (including the transferred one) were discharged home well. Wikipedia lists ten different hospitals/clinical colleges affiliated with Tongji Medical College in Wuhan. The 1st clinical college is called Wuhan Union Hospital. The 2nd clinical college is called Wuhan Tongji Hospital. This series is therefore unlikely to overlap with the various case series from Union Hospital Tongji.

29th March update. Four more primary reports including ten more cases. All previously unreported.

Study 13. Cord blood serology from six babies in China

Six cases reported in JAMA (click here). All births by Caesarean in Zhongnan Hospital, Wuhan. All mothers mild disease. All babies asymptomatic. Since they were born in a different hospital these are probably additional to the other 33 Wuhan neonates reported in JAMA. Revision 16 April: These are from the same hospital as study 1 and may overlap. Therefore removed from running totals.  Citation: Hui Zeng, Chen Xu, Junli Fan, Yueting Tang, Qiaoling Deng, Wei Zhang, Xinghua Long. Antibodies in Infants Born to Mothers With COVID-19 Pneumonia.

Study 12. Case report from China

Case report in JAMA of baby, born at Renmin Hospital, Wuhan, by Caesarean, 23 days after mother developed Covid-19, had IgM antibodies detected in cord blood (click here). This is additional to the two Remnin cases below, because the clinical details differ substantially. Citation: Lan Dong, Jinhua Tian, Songming He, Chuchao Zhu, Jian Wang, Chen Liu, Jing Yang. Possible Vertical Transmission of SARS-CoV-2 From an Infected Mother to Her Newborn. JAMA. Published online March 26, 2020. doi:10.1001/jama.2020.4621

Study 11. Caesarean birth & neonatal infection, China

Case report (click here) of a baby born by Caesarean to an infected mother at Wuhan Tongji Hospital.  The baby was separated from the mother at birth but became infected (pharyngeal PCR at 36 hours). Both mother and baby recovered. I believe this case report is additional to the 33 Wuhan neonatal cases reported in JAMA, because the details (e.g. birth weight) do not align. This is therefore the fourth infected baby born by Caesarean.

Study 10. Two cases from Renmin Hospital, Wuhan, China

Two pregnant doctors with Covid-19 both delivered by Caesarean at term (click here). Also remnin two cases.  Babies separated and not infected. Probably additional to the 33 JAMA Wuhan neonates because neither neonate was transferred to Wuhan Children’s Hospital.

28 March 2020 update. Three more more primary scientific reports.

Study 9. A Caesarean birth from China

This case report is in Chinese but has an English abstract. Click here. It’s from the First Affiliated Hospital, College of Medicine, Zhejiang University School of Medicine, Hangzhou. There appears to be no overlap of the authors with the Zhejiang Caesarean below, so this may be a new case. The Caesarean is reported as being “successful” which presumably means both mother and baby survived. Citation: Kang X, Zhang R, He H, Yao Y, Zheng Y, Wen X, Zhu S. Anesthesia management in cesarean section for a patient with coronavirus disease 2019. Zhejiang Da Xue Xue Bao Yi Xue Ban. 2020 May 25;49(1):0. Chinese. PMID: 32207592   

12 June reconsideration. The hospitals in S9 & S4 are both First Affiliated Hospital Zhejiang University grid.452661.2.  The full Chinese text of S9 seems to be no longer available so not possible to compare clinical details. Assume this is same case as that in S4.

Study 8. The 33 neonatal cases from China

A series of 33 neonates born to mothers who had Covid-19. All from Wuhan Children’s Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan. Reported in JAMA here. It seems possible that some or all of these infants are also included in the other Union Hospital Tongji series below.  Of the 26 neonates delivered by Caesarean three became infected. One born at 30 weeks and 2 days developed RDS, pneumonia and suspected sepsis, and required non-invasive ventilation. The authors speculate that some of his problems were related to prematurity rather than COVID-19. The other two neonates were healthy. All three survived. By inference, although this is not specifically stated in the paper, none of the seven infant born vaginally became infected.  Citation: Lingkong Zeng, Shiwen Xia, Wenhao Yuan, Kai Yan, Feifan Xiao, Jianbo Shao, Wenhao Zhou, Neonatal Early-Onset Infection With SARS-CoV-2 in 33 Neonates Born to Mothers With COVID-19 in Wuhan, China.

Study 7. The Quingdao case, China

This appears to be the first pregnancy case from  that city. Click here. The mother developed Covid-19 at 30 weeks but recovered and was discharged. At the time the report was written the pregnancy was ongoing.

22 March 2020 estimate. Assuming all the Union Hospital Tongji cases overlap, i.e. that Tongji has reported only 15 in total, there have been 38 published cases (39 babies) of Covid-19 infection in pregnancy. There have been no reports in the scientific literature of any maternal deaths, and all neonates have survived and not been infected. Four neonates remain undelivered.

Note 22 March 2020.  David A Schwarz (click here) in a review in Arch Pathol (preprint available March 21st) also makes the total 38 published cases.  However he includes a series published only in Chinese (his reference 17) Zhang I, Jiang Y, Wei M, Cheng BH, Zhou XC, Li J, et al. 湖北地区新型冠状病毒肺炎流行期间孕妇的 384 妊娠结局分析 [Analysis of the Pregnancy Outcomes in Pregnant Women With COVID-19 in Hubei Province]. Zhonghua Fu Chan Ke Za Zhi . 2020;55(0), E009. Available from: http://rs.yiigle.com/yufabiao/1184338.htm (accessed and translated 12 March 2020).  He reports this as including 16 cases.  For the moment I’ve not included this Hubei series, (but see Study 6a added 1 April).

Study 6a. 16 cases from Remnin, China

The cases included by David Schwarz on March 21 (see note above). English abstract (click here). Full text in Chinese here. Google translate used. The authors come from Remnin Hospital, but the paper reports that all 16 women were delivered by Caesarean at the Eastern Hospital of Wuhan University People’s Hospital.  Therefore assume no duplicates.

Study 6. The 15 Union hospital Tongji cases, China

A series of 15 pregnant women, of whom 11 had delivered and four remained undelivered from Union Hospital, Tongji Medical College, click here.

Study 3. The Sun Yat Sen series from China

These 13 cases were reported from the First Affiliated Hospital of Sun Yat-sen University, Guangzhou 510080, Province. Guangdong. (click here). Also pre-publication text 10.1016@j.jinf.2020.02.028). They included 3 patients from Zhejiang, 3 from other cities of Hubei and 1 each from Fujian, Shanxi, Beijing, Guangdong, Jiangxi, Heilongjiang and Anhui.   No infected neonates but one mother seriously ill on ECMO.  16 April update. Since patients in this series came from multiple centres, both in and outside Hubei province, they are likely to overlap with other studies. 12 mothers (3 undelivered) and 9 babies have therefore been removed from the running total. However case 6, where the woman was reported to be on ECMO and the baby stillborn, does not appear to have been reported elsewhere, so remains in the running totals.
