The aim of the study was to analyse the burden of cytomegalovirus (CMV) disease in children undergoing hematopoietic stem cell transplantation (HSCT) and its correlation with all-cause mortality. We performed a retrospective study in children up to 18 years of age who underwent allogeneic HSCT between February 2002 to December 2021 in the pediatric blood and marrow transplantation unit. A total of 1035 patients were included where five hundred forty-three (52.4%) patients underwent matched family donor (MFD) HSCT, 213 (20.5%) underwent matched unrelated donor (MUD) HSCT; 279 (26.9%) underwent haploidentical HSCT (T cell replete in 213 and T cell depleted in 66 patients). CMV reactivation was documented in 258 (24.9% patients). CMV was seen in 39 (7.2%) MFD, 77 (36.1%) MUD, 106 T cell replete (49.7%) and 36 T cell depleted (54.5%) transplants. CMV reactivation was predominantly documented in those where donor and recipient were positive (D + /R +) for CMV serostatus (77%)) prior to HSCT. Overall mortality rate was significantly higher in the CMV positive group (103/258, 39.9%), as compared to the CMV negative group (152/777, 19.6%) ( p value = 0.0001). CMV was the direct cause of death in 13/1035 children (1.2%). GvHD as a cause of death was found to be significantly higher among those with CMV ( n  = 32) as compared to those without CMV ( n  = 14) (35.6 versus 9%, p value = 0.0001). The incidence of CMV reactivation was noted in 25% of HSCT recipients, and predominantly in haploidentical HSCTs. CMV reactivation was shown to significantly impact all-cause mortality and there was a significantly increased risk of mortality due to GvHD among those with CMV reactivation., Competing Interests: Conflict of interestThere are no conflicts of interest., (© The Author(s), under exclusive licence to Indian Society of Hematology and Blood Transfusion 2023.

Background : Very early-onset inflammatory bowel disease (VEOIBD) is defined as IBD in children under six years of age. We present outcome data of hematopoietic stem cell transplantation (HSCT) in the above children. Patients and methods : We performed a retrospective study in children under six years of age who underwent HSCT for VEOIBD with an identified monogenic disorder from December 2012 to December 2020. Results : Of the 25 children included, the underlying diagnosis was IL10R deficiency (n = 4), Wiskott-Aldrich syndrome (n = 4), Leukocyte adhesion defect (n = 4), Hyper IgM syndrome (n = 3), Chronic granulomatous disease (n = 2), and one each with XIAP deficiency, severe congenital neutropenia, Omenn syndrome, Hyper IgE syndrome, Griscelli syndrome, MHC Class II deficiency, LRBA deficiency, and IPEX syndrome. Donors included a matched family donor in 10(40%); a matched unrelated donor in 8 (32%), haploidentical in 7 (28%) (T depleted 16%, T replete with post-transplant cyclophosphamide12%). Conditioning was myeloablative in 84% ofHSCTs. We documented engraftment in 22 (88%) children, primary graft failure in 2 children (8%), mixed chimerism in 6 (24%) children with mortality in 4/6 children. Children with a sustained chimerism of > 95% did not have recurrence of any features of IBD. Overall survival was 64%, with a median follow-up of 55 months. Mixed chimerism was associated with a significantly increased risk of mortality (p-value = 0.001). Conclusions : VEOIBD caused by monogenic disorders can be offered HSCT. Early recognition, optimal supportive care, and complete chimerism are essential components to achieving survival., Competing Interests: Conflict of InterestNone.Conflict of InterestThere are no conflicts of interest., (© The Author(s), under exclusive licence to Indian Society of Hematology and Blood Transfusion 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

We aimed to analyze infections in children undergoing hematopoietic stem cell transplantation (HSCT) until engraftment. The spectrum and risk factors associated will help plan interventions to reduce mortality. We performed a retrospective analysis on the infections, associated risk factors, and mortality until engraftment in children up to 18 years of age undergoing HSCT from January 2017 to August 2020. A total of 399 children were included, with a male: female ratio of 1.9:1, with matched related donor HSCT in 36.6%, a matched unrelated donor in 18.3%, and haploidentical HSCT in 38.1% of children. Culture positive bacteremia was documented in 22.1% transplants with gram-negative bacteria (GNB) isolated in 71/88 (80%). Among the GNB, the predominant organism was Klebsiella pneumonia in 38 (53%), E.coli in 16 (22%), Pseudomonas in 9 (12%). Carbapenem resistance was documented in 24/71 (33%). The incidence of possible, probable, and proven fungal infections in the cohort was 63 (15%), 28 (7%), and 6 (1.5%), respectively. Mortality up to engraftment due to sepsis in our cohort is 3.3% (n = 13). There was a significant association between mortality and a perianal focus (30.8%, p value 0.029) and the presence of carbapenem resistance (38%, p value 0.002). Mortality among those who developed proven fungal infections was significantly higher than those with bacteremia ( p value 0.004). Our study has identified fungal sepsis and carbapenem-resistant GNB sepsis as high-risk groups for mortality. Risk directed interventions in these groups would help ensure survival and optimal outcomes., Competing Interests: Conflict of interestThere are no conflicts of interest., (© Indian Society of Hematology and Blood Transfusion 2021.)

Objective: We present outcome data on hematopoietic stem cell transplantation (HSCT) in children with inborn errors of metabolism (IEM)., Methods: We retrospectively analyzed data on children up to 18 years of age, diagnosed with IEM, who underwent HSCT between January, 2002 and December, 2020., Results: 24 children, (mucopolysaccharidosis - 13, Gaucher disease - 4, X-linked adrenoleukodystrophy - 4, metachromatic leukodystrophy - 2, Krabbe disease - 1) were included. Donors were matched family donors in 24%, matched unrelated donors in 34%, and haploidentical fathers in 42% of the transplants, with engraftment in 91% of children. Overall survival was 72% (55-100%) with a median follow-up of 76.5 (10-120 ) months, and progression-free survival of 68% (MPS-76%, X-ALD -60%, Gaucher disease - 50%, and 100% in MLD and Krabbe disease)., Conclusion: HSCT is an available curative option, and early age at HSCT prevents end-organ damage.

Peripheral T-cell lymphoma (PTCL) is a rare form of lymphoma in children with limited published data on treatment and lack of a uniformly accepted treatment algorithm. We retrospectively analyzed the data in children up to 18 years of age diagnosed to have PTCL from January 2016 to June 2020. The study included six children with a median age of 10 years, the youngest being a 7-month-old girl. According to the WHO-PTCL classification, three had PTCL-not otherwise specified (NOS), 2 had hepatosplenic TCL, and 1 had subcutaneous panniculitis-like TCL. All children had presented with advanced disease, 4 in St. Jude stage IV, 2 in St. Jude stage III. Three children received CHOEP chemotherapy including cyclophosphamide, doxorubicin, vincristine, prednisone, etoposide, while 1 child received CHOP. Two children received induction as per acute lymphoblastic leukemia followed by Bendamustine. Two patients succumbed to progressive disease, the infant with PTCL-NOS and 1 child with hepatosplenic TCL. Three children were in remission (median follow up of 44 mo). One child with PTCL-NOS Stage IV had an underlying STAT3 mutated hyperimmunoglobulin E syndrome and was in remission 12 months post a matched unrelated donor hematopoietic stem cell transplantation. He had grade 4 skin graft versus host disease and required extracorporeal photopheresis and ibrutinib, to which he had responded. CHOEP chemotherapy is well-tolerated and subcutaneous panniculitis-like TCL has the best prognosis thus far., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

We aimed to analyze data in children with primary hemophagocytic lymphohistiocytosis (HLH) who underwent hematopoietic stem cell transplantation (HSCT). We performed a retrospective study where children up to 18 years, with primary HLH and who underwent HSCT from January 2011 to December 2019, were included. Twenty-five children with genetic HLH underwent HSCT, including variants (Griscelli syndrome (GS2) 7, Chediak-Higashi syndrome (CHS) 2, XIAP mutation 2). Donors were matched family 8 (32%), umbilical cord blood unit 3 (12%), matched unrelated 2 (8%), haploidentical HSCT 12 (48%), (TCR alpha/beta depletion 2 and post-transplant cyclophosphamide 10). With treosulfan-based conditioning, engraftment was achieved in 23/25 (92%) transplants (100% in haplo-HSCT), with sustained complete chimerism in 87%. Disease-free survival was noted in 2/3 children with stable mixed chimerism. Graft-versus-host disease (GVHD) of grade I/II was noted in 6 (24%), grade III in 3 (13%); chronic limited skin GVHD in 2 (12%) children. Overall survival was 72% (87.5% in matched donor, 66.7% in the haplo-HSCT), 71% in GS2, 50% in CHS, 100% in XIAP. HSCT is curative in primary HLH with acceptable disease-free survival with mixed chimerism. Haplo-HSCT is a viable option for those without matched family or unrelated donors., Competing Interests: Conflict of interestThere are no conflicts of interest., (© Indian Society of Hematology and Blood Transfusion 2021.)

Background: We aimed to describe an algorithm for the management of cytokine release syndrome (CRS) associated with haploidentical hematopoietic stem cell transplantation (haploSCT)., Patients and Methods: We performed a prospective study where children up to 18 years of age undergoing haploSCT with post-transplant cyclophosphamide from September 2014 to March 2020 were included. Supportive care included low-dose adrenaline, high-flow nasal cannula, and N-acetylcysteine (NAC). Methylprednisolone and tocilizumab were administered in the peri-engraftment phase for grade 2 CRS or one-log increase and grade 3 CRS or a two-log increase in ferritin, respectively., Results: Data were analyzed in 135/148 children as 13 children died before engraftment due to sepsis. CRS was noted in 97% transplants (grade 1-74.1%, grade 2-15.6%, grade 3-6.7%, grade 4-1.4%). Grade 2 and above CRS was higher in non-malignant conditions (33% vs 13%, P-value .009). The percentage median rise in ferritin was 129%-grade 1, 171%-grade 2, and 344%-grade 3. Seven children received tocilizumab, and two of whom had ferritin values greater than 100 000 ng/mL with no mortality in this group. Low-dose adrenaline, high-flow nasal cannula, and ventilator support were needed in 13%, 10%, and 4%, respectively. Mortality in our cohort was 3/135 (2.2%), with two deaths due to sepsis and one due to grade 4 CRS., Conclusions: A risk-stratified approach using steroids in grade 2 and tocilizumab in grade 3/4 in the setting of haploSCT with NAC infusion and early use of low-dose adrenaline and HFNC can help provide adequate control of CRS, thereby ensuring optimal outcomes and survival., (© 2020 Wiley Periodicals LLC.)

We present our experience on the use of fludarabine, cytarabine, granulocyte colony-stimulating factor in combination with Bortezomib. In total, 13 children with relapsed/refractory leukemia (acute lymphoblastic leukemia=9 and acute myeloid leukemia=4) were included from January 2018 to May 2019. Culture-positive sepsis and intensive care unit admission rates were 38% and 30%, respectively, with no postchemotherapy mortality in this cohort. Morphologic remission was documented in 92% and negative minimal residual disease was achieved in 61%, with 100% remission in those with acute myeloid leukemia. These results bear significant relevance in developing countries where multidrug-resistant sepsis is on the rise., Competing Interests: The authors declare no conflict of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

Alternate donor HSCT for thalassemia major from a matched unrelated donor or haploidentical family donor is a feasible therapeutic option in children with no matched family donor. Aggressive pretransplant immunosuppression, reduced toxicity conditioning, and PTCY result in excellent thalassemia-free survival. We describe here our experience in this cohort. We performed a retrospective analysis of the data on children who underwent a haploidentical HSCT for thalassemia major with PTCY at our center from August 2017 to August 2019. All children received pretransplant immune suppression for 6 weeks with fludarabine and dexamethasone, hypertransfusion and chelation with intravenous desferrioxamine. Conditioning included thiotepa, fludarabine, rabbit ATG, and cyclophosphamide, and GvHD prophylaxis included PTCY with tacrolimus. Twenty children were included and nineteen children engrafted. Acute hypertension occurred in five children, bacterial infection in eight children and viral respiratory infection in three children. Three children suffered from graft rejection. Reactivation of viruses namely CMV, adenovirus, and BK virus was seen in 60% of children. Grades 1-2 acute GvHD of the skin in four children (20%) and limited chronic GvHD of the skin in four children (20%). Immune cytopenia was documented in three children (15%). Haploidentical HSCT offers a therapeutic option for children with thalassemia major with no suitably matched family or unrelated donors. Our reduced toxicity regimen with PTCY offers a DFS of 75% and OS of 95% with low transplant-related mortality of 5%., (© 2020 Wiley Periodicals LLC.)

Background: Amikacin is a semisynthetic antibiotic used in the treatment of gram-negative bacterial infections and has a narrow therapeutic index. Although therapeutic drug monitoring is recommended for amikacin, it is not routinely performed because of the use of a less toxic once-daily regimen. Only few studies have evaluated the role of therapeutic drug monitoring in patients treated with amikacin. The objective of our study was to find an association between the pharmacokinetic parameters of amikacin and the time required for a clinical cure, creatinine clearance, and frequency of ototoxicity in patients with urinary tract infection treated for 7 or more days., Methods: A prospective study was conducted on patients with urinary tract infections who were administered amikacin for 7 or more days. Blood samples were obtained from the patients to measure the maximum drug concentration (Cmax) and trough concentration (Ctrough). Minimum inhibitory concentration (MIC) values were determined for patients with positive urine cultures. Serum creatinine levels were estimated every 3 days. The auditory assessment was performed using pure tone audiometry at baseline and weekly until the patients were discharged. Levels of amikacin were analyzed using a validated liquid chromatography-tandem mass spectrometry method., Results: Of 125 patients analyzed, the median time required for a clinical cure was less in the group of patients who achieved a Cmax/MIC ratio ≥8 than it was in those who did not achieve this level [7 versus 8 days (P = 0.02)]. The Ctrough of amikacin was associated with the change in serum creatinine level (P = 0.01) and the incidence of nephrotoxicity (P = 0.004)., Conclusions: In patients receiving short-term amikacin therapy, Cmax/MIC value can be used to predict the time required for a clinical cure. Ctrough can be used to predict the occurrence of nephrotoxicity in patients receiving amikacin therapy.

Fanconi anemia is the most common inherited bone marrow failure syndrome, and hematopoietic stem cell transplantation (HSCT) is the only curative option. Post-transplant cyclophosphamide (PTCy) is challenging in this group of children, given their increased sensitivity to chemotherapy. We performed a retrospective analysis of the data on children diagnosed with Fanconi anemia who underwent a haploidentical HSCT with PTCy from January 2014 to December 2019. Nineteen children (male/female, 0.75:1) underwent 21 haplo-HSCTs with PTCy. Fludarabine, low-dose cyclophosphamide, and 200 centi-gray total body irradiation were included in the conditioning regimen with 25 mg/kg PTCy on days +3 and +4. Haplo-graft was from a sibling in 38% and father in 57% of transplants. The source of stem cells was peripheral blood stem cells in 81% and bone marrow in 19% of transplants, with a median CD34 dose of 5.0 × 10 6 /kg. We documented engraftment in 84% and primary graft failure in 10% of transplants. N-acetylcysteine (NAC) was infused concomitantly during cyclophosphamide in 13 children. Grade 2 and 3 mucositis was lower among those who received NAC as compared to those who did not (30% and 15% versus 33% and 50%), while transaminitis was higher among those who did not receive the infusion. The incidence of acute graft-versus-host disease (GVHD) was 68%, and 81% of these were steroid responsive (grade I/II). We documented chronic GVHD in 25% children, predominantly involving the skin and mouth, which responded to low-dose steroids and ruxolitinib. Serum ferritin was monitored twice weekly as a surrogate marker for cytokine release syndrome due to nonavailability of IL-6 levels. A 1- or 2-log increase in the titers of ferritin associated with clinical features guided the early addition of steroids in the periengraftment period. The mean survival was found to be less among those with high serum ferritin (>10,000 ng/dL) in the periengraftment period as compared to those with ferritin <10,000 ng/dL (mean survival of 25 ± 10 months versus 50 ± 6 months, respectively). The overall survival in our cohort was 68.4%, with a mean survival time of 41.5 months (95% confidence interval, 29.3 to 53.8 months), with a statistically significant correlation between inferior outcome and having received over 15 transfusions before HSCT (P = .01). PTCy can be considered a viable option in children with Fanconi anemia, particularly in resource-limited settings given the high costs of HSCTs. Focused interventions in this subset of children help improve survival outcomes. Early identification of cytokine release syndrome and risk-adapted steroid therapy during engraftment helps prevent mortality. The concomitant use of NAC during cyclophosphamide infusion helps reduce oxygen free radical related tissue damage and regimen-related toxicity., (Copyright © 2020 American Society for Transplantation and Cellular Therapy.

Hematopoietic stem cell transplantation (HSCT) is the only curative option available for patients with thalassemia major in India with increasing access to alternate donor transplantation for patients with no matched family donor. We aimed to analyze the impact of family and alternate donor HSCT on morbidity and mortality post-HSCT. We conducted a retrospective study in the department between July 2007 and December 2018 where all children who underwent HSCT for thalassemia major were included. A total of 264 children were included with a median age of 6 years (male/female, 1.4:1). The graft source was matched related donor (MRD) (76%; parent 15%, sibling 85%) and matched unrelated donor (MUD) (22%). All children received a myeloablative conditioning regimen with treosulfan/thiotepa/fludarabine in 93% and busulfan/cyclophosphamide in 7%. The source of stem cells was peripheral blood in 61%, bone marrow in 38%, and umbilical cord blood in 3%. The incidence of bacteremia was 14% versus 25% in MRD versus MUD groups. There was a higher incidence of posterior reversible encephalopathy syndrome (PRES) in the MUD group (10% versus 3%). Engraftment occurred in 97% with a higher trend toward mixed chimerism in the MRD group (12% versus 2%). When indicated, whole-blood donor lymphocyte infusion was used to ensure complete chimerism in children in the MRD group. A statistically significant difference was found in the incidence of graft versus host disease (GVHD), both acute and chronic between the MUD versus MRD groups, 60% versus 20% and 41% versus 17%, respectively (P = .001). Similarly, immune cytopenia and cytomegalovirus reactivation were also significantly higher in the MUD group, 27% versus 1.4% and 25% versus 2%, respectively (P = .001). Thalassemia-free survival in our cohort was 96%, 94%, and 84% with a median follow-up of 65 months in the matched sibling donor, matched family donor, and MUD groups, respectively. Overall survival of 95% and 90% with a median follow-up of 65 months was noted in those who underwent transplantation less than and greater than 7 years of age, respectively. MUD transplantation for patients with thalassemia major involves specific challenges such as PRES and unusual manifestations of GVHD such as immune cytopenia. Early interventions to optimize supportive care and measures to reduce GVHD are required to ensure survival rates of over 90%., (Copyright © 2020 American Society for Transplantation and Cellular Therapy.

Acute kidney injury (AKI) is a neglected and least studied complication of dengue. AKI secondary to thrombotic thrombocytopenic purpura (TTP) in dengue is extremely rare and there are few case reports. A 2.5-year-old boy with dengue who developed TTP in the critical phase of illness is described. He presented with microangiopathic haemolysis, thrombocytopenia and AKI. Haemolytic uraemic syndrome (HUS)/TTP was suspected and he underwent seven cycles of plasma exchange along with renal replacement therapy, following which he made a complete recovery. Prompt recognition of renal complications in dengue fever and early initiation of appropriate renal replacement therapy along with plasma exchange are essential for a good outcome. Abbreviations : AKI, acute kidney injury; GCS, Glasgow coma scale; HUS, haemolytic uraemic syndrome; LDH, lactate dehydrogenase; NS1, non-structural protein 1; pRIFLE, paediatric risk, injury, failure, loss, end-stage renal disease; SLED, sustained low-efficiency dialysis; TMA, thrombotic microangiopathy; TTP, thrombotic thrombocytopenic purpura.

We present our experience in haploidentical stem cell transplantation (haplo SCT) in children with benign disorders. We performed a retrospective study where children aged up to 18 years diagnosed to have benign disorders and underwent haplo SCT from 2002 to September 2017 were included. Of the 54 children, the most common indications were Fanconi anaemia 12 (22%), severe aplastic anaemia 8 (14%) and primary immune deficiency disorders (PID) 25 (46%). Post-transplant cyclophosphamide (PTCy) was used in 41 (75.9%) and ex vivo T depletion in 13 (24.1%). Engraftment rates were 70% with acute graft versus host disease in 36% and cytomegalovirus reactivation in 55% children. There was a statistically significant difference found between survival with siblings as donors as compared to parents ( p value 0.018). Overall survival was 60% which is the 1-year survival, with 68% survival among those with PIDs. Cytokine release syndrome was noted in 12/41 (29%) of children who received T replete graft and PTCy. In children over 6 months of age, PTCy at a cost of INR 1200 provides cost effective T cell depletion comparable with TCR α/β depletion priced at INR 1200,000. Haplo SCT is feasible option for cure in children with benign disorder., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest.

Collagen, an extracellular matrix protein, has been used for diverse biological applications due to its clinically safe in nature and for the development of various biomedical devices. As the ECM protein is prone to degradation process, it is necessary to stabilize the collagen. In the present study, we have carried out the stabilization of collagen using newly synthesized gold nanoparticles conjugated with Ru(II) complexes (NCs) possessing different ligand environment. From the DLS measurements, the size of the nanoparticles varies from 20 ± 6 nm. Fibrillation assay studies show that the NCs in the presence of photo-irradiation delays the fibrillation process significantly, while in the presence of persulfate, the acceleration in fibrillation process occurs. Circular dichroic and infra-red spectroscopic studies reveal that no alteration in triple helical structure observed for the photo-irradiated samples. SDS-PAGE analysis data reveal that the NCs facilitate the collagen crosslinks and hinders the enzymatic digestion, while neither Au-NPs nor Ru(II) complexes alone did not impart any stability to the collagen. The results from this study help us to understand the photochemical reaction of nanoparticle conjugate on collagen crosslinking and might be helpful in developing new photocatalyst for corneal application., (Copyright © 2019 Elsevier B.V.

Haploidentical stem cell transplantation (haplo SCT) has emerged as an acceptable alternative to matched family donor transplantation for children diagnosed to have primary immune deficiency disorders (PIDs). We present data over 4 years on the challenges and efficacy of unmanipulated T cell replete haplo SCTs with post-transplant cyclophosphamide (PTCy) in children diagnosed to have PIDs. We performed a retrospective study in the pediatric blood and marrow transplantation unit where all children less than 18 years of age diagnosed to have PIDs and who underwent haplo SCT with PTCy from January 2014 to February 2018 were included in the study. Of the 16 transplants included in the study, 5 children were diagnosed to have Wiskott-Aldrich syndrome, 3 with congenital hemophagocytic lymphohistiocytosis, 2 each with Griscelli syndrome and Mendelian susceptibility to mycobacterial diseases, and one each with Chediak-Higashi syndrome, ORAI 1 mutation immune deficiency, severe combined immune deficiency, and Hyper IgM syndrome. The source of stem cells was PBSC in 62.5% and bone marrow in 32.5%. Engraftment by day 16-21 post hematopoietic stem cell transplantation was achieved in 75% transplants with 91% of these remaining in sustained complete chimerism. Acute skin and gut graft versus host disease of grade 2-3 were noted in 50% transplants and cytomegalovirus (CMV) reactivation in 43.7% transplants. One child with congenital HLH succumbed to refractory CMV, adenovirus, and BK virus infection. Cytokine release syndrome (CRS) was noted in 75% transplants with 2 children succumbing to the illness. Tocilizumab was successfully used early in one child. Overall mortality was found to be 37.5% with overall survival of 62.5% with a median follow-up of 23.3 months. In resource limited settings, PTCy has the potential to provide a cost-effective advantage in terms of accessibility of this curative procedure among children with PIDs.

Introduction: Outcome data in pediatric plasma exchange, especially in nonrenal indications are scarce. We aimed to evaluate its role and outcome in our patients., Subjects and Methods: A retrospective study of children admitted in the year 2016 to the Pediatric Intensive Care Unit requiring plasma exchange for nonrenal indications was undertaken. Plasma exchange was given as adjunctive therapy along with primary treatment for the disease concerned. Demographic and clinical data were studied, and descriptive statistical analysis was carried out., Results: Ten children underwent plasma exchange during this 1-year period with a male: female ratio of 3:2 and a mean age of 10 years (range 3-16 years). The indications were acute disseminated encephalomyelitis ( n = 2), acute neuromyelitis optica ( n = 1), catastrophic antiphospholipid antibody syndrome secondary to systemic lupus erythematosus (SLE) ( n = 1), severe SLE with cerebritis/hemophagocytic lymphohistiocytosis (HLH) ( n = 2), severe dengue sepsis with HLH/multi-organ dysfunction syndrome ( n = 2), and thrombotic microangiopathy secondary to snake bite envenomation ( n = 2). All received either 1.5 or 2 times plasma volume exchange (mean sessions - 4, range = 1-6). The mean duration of stay in hospital was 17.2 days (range = 3-40 days), and follow-up was 78 days (range = 3-180 days), with the majority of children (8/10, 80%) survived from the catastrophic illness at the time of discharge. Two children (2/10, 20%) succumbed due to the disease per se in severe dengue sepsis in one and enterobacteriaceae sepsis (hospital-acquired pneumonia) in another., Conclusion: Plasma exchange was found to be beneficial as complementary therapy in a critical care setting, especially for nonrenal indications., Competing Interests: There are no conflicts of interest.

Objectives: To evaluate the cardiovascular aberrations using multimodal monitoring in fluid refractory pediatric septic shock and describe the clinical characteristics of septic myocardial dysfunction., Design: Prospective observational study of patients with unresolved septic shock after infusion of 40 mL/kg fluid in the first hour., Setting: Two tertiary care referral Indian PICUs., Patients: Patients aged 1 month to 16 years who had fluid refractory septic shock., Interventions: Changes in therapy were based on findings of clinical assessment, bedside echocardiography, and invasive blood pressure monitoring within 6 hours of recognition of septic shock., Measurements and Main Results: Over a 4-year period, 48 patients remained in septic shock despite at least 40 mL/kg fluid infusion. On clinical examination, 21 patients had cold shock and 27 had warm shock. Forty-one patients (85.5%) had vasodilatory shock on invasive blood pressure; these included 14 patients who initially presented with cold shock. The commonest echocardiography findings were impaired left ± right ventricular function in 19 patients (39.6%) and hypovolemia in 16 patients (33%). Three patients who had normal myocardial function on day 1 developed secondary septic myocardial dysfunction on day 3. Echocardio graphy, along with invasive arterial pressure monitoring, allowed fluid, inotropy, and pressors to be titrated more precisely in 87.5% of patients. Shock resolved in 46 of 48 patients (96%) and 44 patients (91.6%) survived to discharge., Conclusion: Bedside echocardiography provided crucial information leading to the recognition of septic myocardial dysfunction and uncorrected hypovolemia that was not apparent on clinical assessment. With invasive blood pressure monitoring, echocardiography affords a simple noninvasive tool to determine the cause of low cardiac output and the physiological basis for adjustment of therapy in patients who remain in shock despite 40 mL/kg fluid.

A 5-month-old infant with Shaken Baby Syndrome is reported. This form of physical child abuse is often overlooked. It should be suspected in infant who present with drowsiness, coma, seizures or apnea.
