Sepsis, severe sepsis and septic shock in paediatric multiple organ dysfunction syndrome

Goh A, Lum L

J Paediatr Child Health, 1999 Oct;35(5):488-92.
PMID: 10571765

OBJECTIVES: To determine the association between severity of sepsis with outcome and severity of illness in children with multiple organ dysfunction syndrome (MODS).
MATERIALS: Four hundred and ninety-five consecutive paediatric intensive care unit (PICU) admissions were analysed. multiple organ dysfunction syndrome was defined as simultaneous dysfunction of >/= 2 organ system and sepsis by the American College of Chest Physicians and Society of Critical Care Medicine Consensus Conference definition.
RESULTS: Eighty-four patients developed MODS. The incidence of sepsis, severe sepsis and septic shock in these patients was 10.7%, 23.8% and 17.9%, respectively. Worsening categories of sepsis were associated with: (1) a higher mean admission Paediatric Risk of Mortality (PRISM II): 36.6 +/- 25.9, 56.8 +/- 32.1 and 73.6 +/- 28.5%, respectively (P = 0. 005), (2) a larger number of organ dysfunctions: mean MODS index of 37%, 46% and 58%, respectively (P = 0.007), and (3) a higher mortality: 22.2%, 65% and 80%, respectively (P = 0.03).
CONCLUSION: Presence of sepsis, severe sepsis and septic shock was associated with an increasing severity of illness, increased number of organ dysfunctions and a distinct risk of mortality among critically ill children.

High cut-off hemofiltration versus standard hemofiltration: effect on plasma cytokines

Atan R, Peck L, Visvanathan K, Skinner N, Eastwood G, Bellomo R, et al.

Int J Artif Organs, 2016 Nov 11;39(9):479-486.
PMID: 27834446 DOI: 10.5301/ijao.5000527

PURPOSE: To study the effects of continuous veno-venous hemofiltration (CVVH) with high cut-off filters (CVVH-HCO) on plasma cytokine levels, sieving coefficient and clearance compared to CVVH using standard filters (CVVH-Std) in a nested cohort within a double-blind randomized controlled trial in severe acute kidney injury (AKI) patients.
METHODS: We measured plasma and post-filter levels of IL-6, TNF-alpha, IL-8, IL-1 beta, RANTES, IL-10, IFN-gamma and IFN-alpha in both study groups. We also measured cytokine levels in the ultrafiltrate and calculated sieving coefficients and clearances.
RESULTS: By 72 hours of treatment, IL-6 had decreased during both treatments (p = 0.009 and 0.005 respectively). In contrast, IL-10 had decreased with CVVH-Std (p = 0.03) but not CVVH-HCO (p = 0.135). None of the other cytokines showed changes over time. There were also no significant between group differences in plasma levels for each cytokine over the 72-hour treatment period. For all cytokines combined, however, the median sieving coefficient was higher for CVVH-HCO (0.31 vs. 0.16; p = 0.042) as was the mass removal rate by ultrafiltration (p = 0.027). While overall combined cytokine levels had fallen to 62.2% of baseline at 72 hours for CVVH-HCO (p<0.0001) and to 75.9% of baseline with CVVH-Std (p = 0.008) there were no between group differences.
CONCLUSIONS: CVVH-HCO achieved greater combined sieving coefficient and mass removal rate by ultrafiltration for a group of key cytokines than CVVH-Std. However, this effect did not differentially lower their plasma level over the first 72 hours. Our study does not support the use of CVVH-HCO to lower cytokines in critically ill patients with AKI.

Fulltext Comprehensive care of a patient with obesity of BMI >70 kg/m2

Kabir S, Hossain AT, Shimmi SC, Jie CS

BMJ Case Rep, 2020 Dec 28;13(12).
PMID: 33372011 DOI: 10.1136/bcr-2020-236197

A 31-year-old woman, with a body mass index of 70.31 kg/m2, presented with progressive worsening of dyspnoea for 3 days. She had multiple comorbidities, including obesity hypoventilation syndrome. The patient developed type II respiratory failure with respiratory acidosis along with multiorgan failure. She was intubated and put on a mechanical ventilator and treated with intravenous diuretics, subcutaneous low-molecular-weight heparin and other supportive measures. Later, she was on noninvasive, continuous positive airway pressure ventilation overnight. She was prescribed a very-low-calorie diet along with physiotherapy and exercise. The patient underwent bariatric surgery 2 months after resolution of acute illness. Ten months after surgery, her body weight reduced from 180 kg to 121 kg, and her general condition improved. Successful management before and after surgical intervention depends on multidisciplinary teamwork, which includes the dietician, physiotherapist, endocrinologist, pulmonologist, nursing care and other supportive care.

A novel ITPA variant causes epileptic encephalopathy with multiple-organ dysfunction

Sakamoto M, Kouhei D, Haniffa M, Silva S, Troncoso M, Santander P, et al.

J Hum Genet, 2020 Sep;65(9):751-757.

Inborn errors of metabolism can cause epileptic encephalopathies. Biallelic loss-of-function variants in the ITPA gene, encoding inosine triphosphate pyrophosphatase (ITPase), have been reported in epileptic encephalopathies with lack of myelination of the posterior limb of the internal capsule, brainstem tracts, and tracts to the primary visual and motor cortices (MIM:616647). ITPase plays an important role in purine metabolism. In this study, we identified two novel homozygous ITPA variants, c.264-1 G > A and c.489-1 G > A, in two unrelated consanguineous families. The probands had epilepsy, microcephaly with characteristic magnetic resonance imaging findings (T2 hyperintensity signals in the pyramidal tracts of the internal capsule, delayed myelination, and thin corpus callosum), hypotonia, and developmental delay; both died in early infancy. Our report expands the knowledge of clinical consequences of biallelic ITPA variants.
