Abstract
Sepsis is a leading cause of neonatal mortality and morbidity in low and middle-income countries. We designed a double-blinded randomised controlled trial in a neonatal intensive care unit (NICU) of a tertiary care teaching hospital to determine the role of intravenous immunoglobulin (IVIG) in decreasing hospital stay. Eighty neonates with clinical features of sepsis were enrolled in the study and placebo groups to receive 500 mg/kg of IVIG for three consecutive days or a placebo. The primary outcome measure was duration of hospital stay in days. The babies in both groups were comparable in terms of birth weight, gestation and sex distribution. There was no significant difference in duration of hospital stay (days) in the study and placebo groups. We found that treatment with IVIG did not shorten the duration of hospital stay in our setting.

Abstract
OBJECTIVES To summarize the role of therapeutic plasma exchange (TPE) in critically ill adults and children with severe sepsis. DATA COLLECTION A systematic search was performed using the following databases: Medline, EMBASE, CINAHL, and Cochrane from January 1990 till December 2022. Comparative studies of TPE in severe sepsis were selected. Adult and pediatric data were analyzed separately. DATA SYNTHESIS Eight randomized control trials and 6 observational studies (n = 50,142 patients) were included. Centrifugal TPE was the most common modality (209/280, 74.6% adults and 952/1026, 92.7% children). Every TPE study utilized different volume exchanges. Most TPE sessions (1173/1306, 89.8%) employed fresh frozen plasma (FFP) as replacement fluid and heparin as anticoagulant. Adults with severe sepsis supported with TPE using FFP had lower mortality (risk ratio, RR: 0.64 [95% confidence interval, CI: 0.49, 0.84]) compared to those who did not. In contrast, TPE was associated with increased mortality in septic children without thrombocytopenia-associated multiorgan failure (RR: 2.23, 95% CI: 1.93, 2.57). There was no difference in outcomes in patients supported with centrifugal and membrane TPE. In both populations, patients supported on TPE as a continuous regime had poorer outcome. CONCLUSION Current evidence indicates that TPE is a potential adjunct therapy in adults with severe sepsis but not in children.
PICO Summary
Population
Critically ill adults and children with severe sepsis or septic shock (14 studies, n= 50,142).
Intervention
Therapeutic plasma exchange (TPE) alone, or in combination with hemofiltration, hemadsorption, or conventional treatment of sepsis.
Comparison
Various comparators, including: other forms of blood purification therapy, immunomodulation and conventional treatment.
Outcome
Centrifugal TPE was the most common modality (209/280, 74.6% adults and 952/1,026, 92.7% children). Every TPE study utilized different volume exchanges. Most TPE sessions (1,173/1,306, 89.8%) employed fresh frozen plasma (FFP) as replacement fluid and heparin as anticoagulant. Adults with severe sepsis supported with TPE using FFP had lower mortality (risk ratio (RR), 0.64 [95% confidence interval (CI) [0.49, 0.84]) compared to those who did not. In contrast, TPE was associated with increased mortality in septic children without thrombocytopenia-associated multiorgan failure (RR, 2.23; 95% CI [1.93, 2.57]). There was no difference in outcomes in patients supported with centrifugal and membrane TPE. In both populations, patients supported on TPE as a continuous regime had poorer outcome.

Journal of neonatal-perinatal medicine. 2022
Abstract
BACKGROUND Despite appropriate antibiotic therapy, the risk of mortality in neonatal sepsis still remains high. We conducted a systematic review to comprehensively evaluate different adjuvant therapies in neonatal sepsis in a network meta-analysis. METHODS We included randomized controlled trials (RCTs) and quasi-RCTs that evaluated adjuvant therapies in neonatal sepsis. Neonates of all gestational and postnatal ages, who were diagnosed with sepsis based on blood culture or sepsis screen were included. We searched MEDLINE, CENTRAL, EMBASE and CINAHL until 12th April 2021 and reference lists. Data extraction and risk of bias assessment were performed in duplicate. A network meta-analysis with bayesian random-effects model was used for data synthesis. Certainty of evidence (CoE) was assessed using GRADE. RESULTS We included 45 studies involving 6,566 neonates. Moderate CoE showed IVIG [Relative Risk (RR); 95% Credible Interval (CrI): 1.00; (0.67-1.53)] as an adjunctive therapy probably does not reduce all-cause mortality before discharge, compared to standard care. Melatonin [0.12 (0-0.08)] and granulocyte transfusion [0.39 (0.19-0.76)] may reduce mortality before discharge, but CoE is very low. The evidence is also very uncertain regarding other adjunctive therapies to reduce mortality before discharge. Pentoxifylline may decrease the duration of hospital stay [Mean difference; 95% CrI: -7.48 days (-14.50-0.37)], but CoE is very low. CONCLUSION Given the biological plausibility for possible efficacy of these adjuvant therapies and that the CoE from the available trials is very low to low except for IVIG, we need large adequately powered RCTs to evaluate these therapies in sepsis in neonates.

The effect of exchange transfusion on mortality in neonatal sepsis: a meta-analysis
Mathias S, Balachander B, Bosco A, Britto C, Rao S
European journal of pediatrics. 2021
Abstract
Although antimicrobials are the cornerstone of neonatal sepsis management, adjunctive therapies are required to improve outcomes. The aim of our study was to evaluate the effect of exchange transfusion (ET) on mortality (primary outcome) in neonatal sepsis, as well as on immunoglobulin, complement and neutrophil levels and assess its complications (secondary outcomes). Databases searched include PubMed, NCBI, Google Scholar, CINHAL, Ovid and Scopus. Randomized controlled trials (RCTs), controlled observational studies (COSs) and uncontrolled observational studies (UOSs) reporting mortality data from using ET in neonatal sepsis were included. Studies with additional interventions, non-septic ET indications and populations aged > 28 days were excluded. Data extracted include demographics, features of study, sepsis and ET, as well as mortality rates, immunological and laboratory changes and complications. Data was meta-analysed and displayed using forest plots. The meta-analysis of 14 studies (3 RCTs, 11 COSs) revealed a mortality benefit in septic neonates who underwent ET-RR 0.72 (CI 0.61-0.86, p = 0.01) and a significant increase in pooled immunological parameters (immunoglobulin, complement levels) (SMD 1.13, [0.25, 2.02], p = 0.02) and neutrophil levels (SMD 1.07 [0.04, 2.11], p = 0.03) compared to controls. The descriptive analysis of 9 UOSs revealed thrombocytopenia as the most frequently reported complication (n = 48). Moderate-high risk of bias was largely due to inadequate sample sizes and follow-up durations.Conclusion: Currently, the use of ET in neonatal sepsis is not directly recommended due to low certainty of evidence, inadequate power and moderate-high risk of bias and heterogeneity.Trial registration: PROSPERO (CRD42020176629) ( https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=176629 ) What is Known: • Exchange transfusion is one of the adjunctive methods for treatment of neonatal sepsis. What is New: • The pooled analysis of all studies shows that exchange transfusion has a low certainty of evidence in the context of neonatal mortality. However, at this point, this intervention cannot be refuted or recommended due to heterogeneity of studies and inadequate power.

Nassir KF, Al-Saddi YI, Abbas HM, Al Khames Aga QA, Al Khames Aga LA, Oudah AA
Indian journal of pharmacology. 2021;53(5):364-370
Abstract
OBJECTIVES The purpose of this research was to determine the effectiveness of Pentaglobin® as adjuvant therapy in the treatment of sepsis in preterm newborns. MATERIALS AND METHODS It was a prospective, observational, randomized study for 272 premature neonates and very low birth weight (VLBW) that were diagnosed with sepsis carried at neonatal intensive care units. The patients randomized into control group who received standard sepsis antibiotic treatments, and an intervention group who received Pentaglobin® 5 ml/kg daily for 3 consecutive days as an adjunct therapy to a standard sepsis antibiotic treatment. RESULTS Multiple organisms that isolated from culture specimens were Gram-negative bacteria, Gram-positive, and candida (56.25%, 42.28%, and 1.47%, respectively). The disease duration was distinctively longer in patients who were treated by the standard antibiotic protocol (mean ± standard deviation [SD]: 30.76 ± 3.97, odds ratio [OR]: 30.76, 95% confidence interval [CI]: 30.051, 31.473) comparing to the patients who received Pentaglobin adjuvant therapy (mean ± SD: 26.48 ± 5.55, OR: 26.48, 95% CI: 25.489, 27.477) (P < 0.000). Patients treated by standard antibiotic protocol were associated to a substantially increased risk of death (11.76%, hazard ratio 4.400, 95% CI: 1.432, 13.529, P = 0.009). CONCLUSION Neonatal sepsis is more common in premature and VLBW newborns, and Pentaglobin® management of newborn nosocomial sepsis might be used in addition to other therapies.

Journal of neonatal-perinatal medicine. 2021
Abstract
BACKGROUND Refractory septic shock in neonates is still associated with high mortality, necessitating an alternative therapy, despite all currently available treatments. This study aims to assess the vasopressor effect of methylene blue (MB) in comparison to terlipressin (TP) as adjuvant therapy for refractory septic shock in the preterm neonate. METHODS A double-blinded randomized controlled trial was conducted in the Neonatal Intensive Care Units at Ain Shams University, Egypt. Thirty preterm neonates with refractory septic shock were randomized to receive either MB or TP as an adjuvant to conventional therapy. Both MB and TP were administered as an intravenous loading dose followed by continuous intravenous infusion. The hemodynamic variables, functional echocardiographic variables, and oxidant stress marker were assessed over a 24 h period together with the side effects of MB. RESULTS MB causes significant improvement in mean arterial blood pressure with a significant decrease of the norepinephrine requirements (1.15±0.21μm/kg/min at baseline vs. 0.55±0.15μm/kg/min at 24 h). MB infusion causes an increase of the pulmonary pressure (44.73±8.53 mmHg at baseline vs. 47.27±7.91 mmHg after 24 h) without affecting the cardiac output. Serum malonaldehyde decreased from 5.45±1.30 nmol/mL at baseline to 4.40±0.90 nmol/mL at 24 h in the MB group. CONCLUSION Administration of MB to preterm infants with refractory septic shock showed rapid increases in systemic vascular resistance and arterial blood pressure with minimal side effects.

Abstract
Critically ill children with sepsis may develop catastrophic thrombotic and hemorrhagic syndrome of disseminated intravascular coagulopathy as a final common pathway. OBJECTIVES Evaluation of the outcome of early hemostatic management of disseminated intravascular coagulopathy in patients with severe sepsis/septic shock admitted to PICU, before the development of clinically overt disseminated intravascular coagulopathy. DESIGN Prospective interventional, open label randomized controlled clinical trial. SETTING PICU at Alexandria University Children's Hospital. PATIENTS The study included 80 patients with proven severe sepsis/septic shock in nonovert disseminated intravascular coagulopathy stage. They were randomly assigned into two groups (group 1 and group 2). INTERVENTIONS Specific intervention was applied for group 1 (plasma transfusion, low-dose unfractionated heparin, and tranexamic acid). MEASUREMENTS All patients had assessment of Pediatric Index of Mortality 2 score, Pediatric Logistic Organ Dysfunction score, inotropic score, routine laboratory, and hemostatic tests including fibrin degradation products and D-dimers. Disseminated intravascular coagulopathy risk assessment scores were calculated on daily basis. RESULTS Mortality rate was significantly higher in group 2. Progression to overt disseminated intravascular coagulopathy was significantly more common among group 2 patients than group 1 (45% and 10%, respectively) (p < 0.0001). Disseminated intravascular coagulopathyRisk Assessment Scores were significantly higher on the second and fifth days among group 2 patients. The initial specific hemostatic intervention was the only significant predictor of survival and prevention of progression to overt disseminated intravascular coagulopathy. CONCLUSIONS Our results suggest that early use of a combination of fresh frozen plasma transfusion, low-dose heparin, and tranexamic acid in children with severe sepsis/septic shock in the "window of opportunity" before the development of overt disseminated intravascular coagulopathy stage was associated with better outcome for survival and prevention of progression to overt disseminated intravascular coagulopathy, with no increase in bleeding risk. Larger multicenter studies are needed to further prove this practice.

Bancalari Molina A, Munoz Perez T, Martinez Bengoechea P
Journal of neonatal-perinatal medicine. 2019
Abstract
BACKGROUND Neonatal infections are a leading cause of morbi-mortality despite advances in antimicrobials and neonatal care. Preterm infants have greater susceptibility to sepsis due to an immature immune system and lower immunoglobulin levels. Intravenous immunoglobulins (IVIG) have been used in several studies as an adjuvant treatment to improve this physiological immune deficiency, with different outcomes. METHODS Very low birth weight (VLBW) infants who developed sepsis in the neonatal ICU were studied. They were randomly divided in 2 groups: one group was treated with antibiotics (Group I), and the other received antibiotics plus a 500 mg/kg/dav of IVIG during 7 days (Group II). Serum IgG concentration was determined at initiation, during and after treatment Group I, and daily during the 7 days of therapy in Group II. RESULTS The baseline IgG concentration in group II was 486 g/dL, and increased to 852 mg/dL after the first dose of IVIG (p < 0.01). After the seventh day of infusion a mean IgG level of 1898 mg/dL was achieved. A direct correlation (r = 0.94) between IgG concentration and days of treatment was observed. Blood cultures were positive in 70% of the infants in group I and 75.5% in group II. Staphylococcus epidermidis was the most frequent isolated bacteria in blood cultures. The lethality rate was 25.0% in group I and 5.0% in Group II (p < 0.03). We did not observe collateral effects with the administration of IVIG. CONCLUSIONS Therapy with IVIG seems to be safe and effective as an adjuvant treatment in VLBW infants with sepsis.

Aradhya AS, Sundaram V, Kumar P, Ganapathy SM, Jain A, Rawat A
Indian Journal of Pediatrics. 2016;83((2)):107-13.
Abstract
OBJECTIVES To study the efficacy and safety of double volume exchange transfusion (DVET) in neonates>1000 g birth weight with severe sepsis. METHODS Eighty-three neonates weighing >1000 g with severe sepsis were randomly assigned to DVET or standard therapy (ST) group. Primary outcome was mortality by 14 d from enrollment. RESULTS A 21 % reduction in mortality, albeit non-significant, by 14 d from enrollment was observed in DVET group in comparison to ST group [RR: 0.79 (95 % C.I 0.45-1.3); p 0.4]. A similar trend in mortality reduction was observed with early mortality and mortality by discharge in DVET group. No difference was observed in normalization of dysfunctional organs by 14 d. Cardiovascular and hematological system benefitted the most, followed by renal dysfunction with DVET. A significant improvement in post DVET IgG, IgA, IgM, C3 and base deficit was observed. No serious adverse effects occurred following DVET. CONCLUSIONS In neonates >1000 g with severe sepsis, DVET was associated with a trend towards decrease in mortality by 14 d from enrollment. A significant improvement in immunoglobulin and complement C3 levels and acid base status were observed following DVET. DVET is a safe procedure in severely sick and septic neonates.

Abstract
BACKGROUND Severe anaemia in children is a leading cause of hospital admission and a major cause of mortality in sub-Saharan Africa, yet there are limited published data on blood transfusion in this vulnerable group. METHODS We present data from a large controlled trial of fluid resuscitation (Fluid Expansion As Supportive Therapy (FEAST) trial) on the prevalence, clinical features, and transfusion management of anaemia in children presenting to hospitals in three East African countries with serious febrile illness (predominantly malaria and/or sepsis) and impaired peripheral perfusion. RESULTS Of 3,170 children in the FEAST trial, 3,082 (97%) had baseline haemoglobin (Hb) measurement, 2,346/3,082 (76%) were anaemic (Hb <10 g/dL), and 33% severely anaemic (Hb <5 g/dL). Prevalence of severe anaemia varied from 12% in Kenya to 41% in eastern Uganda. 1,387/3,082 (45%) children were transfused (81% within 8 hours). Adherence to WHO transfusion guidelines was poor. Among severely anaemic children who were not transfused, 52% (54/103) died within 8 hours, and 90% of these deaths occurred within 2.5 hours of randomisation. By 24 hours, 128/1,002 (13%) severely anaemic children had died, compared to 36/501 (7%) and 71/843 (8%) of those with moderate and mild anaemia, respectively. Among children without severe hypotension who were randomised to receive fluid boluses of 0.9% saline or albumin, mortality was increased (10.6% and 10.5%, respectively) compared to controls (7.2%), regardless of admission Hb level. Repeat transfusion varied from <2% in Kenya/Tanzania to 6 to 13% at the four Ugandan centres. Adverse reactions to blood were rare (0.4%). CONCLUSIONS Severe anaemia complicates one third of childhood admissions with serious febrile illness to hospitals in East Africa, and is associated with increased mortality. A high proportion of deaths occurred within 2.5 hours of admission, emphasizing the need for rapid recognition and prompt blood transfusion. Adherence to current WHO transfusion guidelines was poor. The high rates of re-transfusion suggest that 20 mL/kg whole blood or 10 mL/kg packed cells may undertreat a significant proportion of anaemic children. Future evaluation of the impact of a larger volume of transfused blood and optimum transfusion management of children with Hb of <6 g/dL is warranted.
