RESUMO

PURPOSE: Spina bifida is a major disorder that occurs when the membranes of the spinal cord and medulla fail to close during the embryonic period and affects the individual for the rest of life. Some physical, mental, and social difficulties can be observed in the lives of children with spina bifida after surgery. The aim of this study is to determine what kind of volumetric changes occur in the brain when spina bifida occurs in different regions of the cord. METHODS: The volume of intracranial structures of 14 children aged 1 to 9 years (7 cervical, 7 lumbosacral) with different levels of spina bifida compared with vol2Brain. RESULTS: Spina bifida occurring in the cervical region was found to cause a greater volumetric reduction in subcortical structures, cortex and gyrus than spina bifida occurring in the lumbosacral region. CONCLUSION: We believe that our study will help clinicians involved in the management of this disorder.

RESUMO

OBJECTIVE: This research was conducted to evaluate the effects of gentle human touch (GHT) on pain, comfort, and physiologic parameters in preterm infants during heel lancing. METHOD: This prospective, assessor-blind, randomized controlled study was performed between August 10, 2021 and September 10, 2021 in the Neonatal Intensive Care Units (NICU) of a tertiary hospital in the Central Anatolia Region of Turkey. Fifty preterm infants were randomly appointed to GHT and control groups. The researcher applied GHT to the infants in the GHT group by placing one hand on the infant's head and the other hand on the lower abdomen covering the waist and hips for 15 min. Data were collected with a Questionnaire, Physiological Parameters Observation Form, Newborn Infant Pain Scale (NIPS), The Comfort Scale (COMFORT), and Pulse Oximeter. RESULTS: The NIPS and COMFORT mean scores of preterm infants in the GHT group were lower during (p < 0.001, p < 0.05, respectively) and after heel lancing (p < 0.05, p < 0.001, respectively). There was no difference between the preterm infants' peak heart rate, respiratory rate, and SPO2 values in the GHT and control groups during and after heel lancing (p > 0.05). The study found that preterm infants in the GHT group had less crying time during the heel lancing (p < 0.001). CONCLUSION: It could recommend using in painful procedures because GHT may positively affect preterm infants' pain, comfort, and physiologic parameters. The results of this study will contribute to NICU nurses should include non-pharmacological methods such as GHT to decrease pain of preterm infants in procedural pain. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05001191).

RESUMO

OBJECTIVES: Arthrogryposis multiplex congenita-5 (AMC5) is an autosomal recessive disease caused by homozygous or compound heterozygous mutations in the TOR1A gene on chromosome 9q34. Congenital multiple joint contractures with microcephaly, typical facial dysmorphism, developmental delay, strabismus, tremor, and increased tone are the main characteristics defined in seven patients thus far. One third of the individuals with monoallelic mutations of the gene develop isolated early-onset dystonia (DYT1 dystonia), which is inherited in an autosomal dominant fashion, with variable expressivity and incomplete penetrance. We believe that different inheritance patterns of the same gene resulting in different phenotypes will provide an opportunity to understand other similar disease groups and different aspects of gene functions. CASE PRESENTATION: We present a case with severe arthrogryposis multiplex congenita, respiratory failure, and feeding difficulties, with additional hitherto unreported symptoms, such as spontaneous bone fracture, sliding esophageal hernia, and uterine prolapse. The patient carried a novel homozygous variant (c.835delA, p.Lys275Asnfs*3) in the TOR1A gene (NM_000113.2). CONCLUSIONS: We want to contribute to the phenotypic and genotypic spectra of this extremely rare disease.

RESUMO

OBJECTIVE: This study aimed to detect which of the two main medicines suggested in the treatment of postligation cardiac syndrome (PLCS)-dobutamine or mirinone-possesses a more therapeutic effect. While doing this, clinicians are provided with a broader perspective on the treatment and follow-up of cases. The desire was to increase the treatability and monitor ability of the cases in question and hence their survivability. STUDY DESIGN: A retrospective review of a cohort of infants with PLCS was conducted between March 2012 and December 2018. In the treatment of infants with PLCS, dobutamine (dobutamine study group-DSG) or milrinone (milrinone study group-MSG) was used. The respiration, cardiac, echocardiography, and perfusion parameters of the cases were assessed both before and after ligation. Based on the data obtained, both the effects of the medicines on PLCS and the difference between their therapeutic effects were studied. The accuracy of prognostication was assessed with receiver operating characteristic analyses. RESULTS: PLCS was detected in 29 (34.1%) of 85 patent ductus arteriosus ligation cases in total. Of all the PLCS cases, 13 (44.8%) were treated with dobutamine and 16 (55.2%) with milrinone. It was observed that the effects of the medicines on the respiratory system and cardiovascular system manifested in the third and 6th hour, respectively. It was detected that both medicines had more effect on the systolic blood pressure (SBP) (area under the curve [AUC]: 0.997/0.996, p = 0.001/0.002) than on the diastolic blood pressure (AUC: 0.911/0.843, p = 0.032/0.046). CONCLUSION: Dobutamine and milrinone, two primary medicines that can be used in the treatment of cases with PLCS, possess similar therapeutic effects on this pathology. In addition, their postoperative therapeutic effects on the SBP are more in the foreground.

RESUMO

PURPOSE: This randomized controlled double-blinded experimental study was carried out to determine the effects of the daily exercise program on bone mineral density and cortisol level in preterm infants with VLBW matched for birth weight, gestation week, and gender. DESIGN AND METHODS: The study was carried out with preterm infants (n = 24) hospitalized in the NICU of a tertiary hospital. Ethical committee approval, institutional permission, parental written consent were obtained. A daily exercise program was implemented in preterm infants in the exercise group for 30 days, once a day, and continuing for 7-10 min. Before and after the study the following were evaluated in preterm infants in the exercise and control group: anthropometric measurements, tibia speed of sound (SOS) for bone mineral density, serum cortisol levels. RESULTS: Serum cortisol levels (p = 0.05) were decreased, bone SOS values in the exercise group were increased (p = 0.009), after the study. The difference between pre-, post-study bone SOS and serum cortisol values of infants in the exercise group were high (p > 0.05). Percentage increases in anthropometric values in the exercise group were higher than the control group after the study (for all; p > 0.05). CONCLUSIONS: The daily exercise program has positive effect on bone SOS and serum cortisol values in preterm infants. Neonatal nurses can implement the daily exercise program in clinical practice.

RESUMO

OBJECTIVE: Hypoxic-ischemic (HI) brain injury in the human perinatal period often leads to significant long-term neurobehavioral dysfunction in the cognitive and sensory-motor domains. Using a neonatal HI injury model (unilateral carotid ligation followed by hypoxia) in postnatal day seven rats, the present study investigated the long-term effects of HI and potential behavioral protective effect of pentoxifylline. METHODS: Seven-day-old rats underwent right carotid ligation, followed by hypoxia (FiO2 = 0.08). Rats received pentoxifylline immediately after and again 2 hours after hypoxia (two doses, 60‒100 mg/kg/dose), or serum physiologic. Another set of seven-day-old rats was included to sham group exposed to surgical stress but not ligated. These rats were tested for spatial learning and memory on the simple place task in the Morris water maze from postnatal days 77 to 85. RESULTS: HI rats displayed significant tissue loss in the right hippocampus, as well as severe spatial memory deficits. Low-dose treatment with pentoxifylline resulted in significant protection against both HI-induced hippocampus tissue losses and spatial memory impairments. Beneficial effects are, however, negated if pentoxifylline is administered at high dose. CONCLUSION: These findings indicate that unilateral HI brain injury in a neonatal rodent model is associated with cognitive deficits, and that low dose pentoxifylline treatment is protective against spatial memory impairment.

RESUMO

OBJECTIVE: Intraventricular hemorrhage (IVH) is an important problem in neonatal units not only in terms of its consequences but also its follow-up and the prediction of its emergence in newborns. In this study, we have compared platelet parameters such as platelet count (PC), mean platelet volume (MPV), and platelet mass index (PMI) in terms of IHV in very-low-birth-weight (VLBW) newborns. Thus, we have tried to determine platelet values to guide clinicians in both the prediction and follow-up of IVH. STUDY DESIGN: This is a retrospective, multicenter, and case-controlled study. In this study, 386 cases of VLBW newborns (below 1,500 g) and gestational age below 32 weeks, hospitalized and monitored between August 8, 2012, and April 7, 2018, were included. The platelet values of the cases on their 12th hour postpartum (PC1, MPV1, and PMI1) and the platelet values on days 5 to 7 (PC2, MPV2, and PMI2) were recorded in their study cards. A p-value of <0.05 was accepted as statistically significant. RESULTS: While there was no difference of PC1, MPV1, PMI1, PC2, or MPV2 values (p > 0.05), PMI2 values in the severe stage IVH group cases were found to be significantly lower compared with other platelet parameters (p < 0.05). CONCLUSION: PMI2 values can provide clinicians with important knowledge that may aid them in recognizing important pathologies such as IVH.

RESUMO

The aim of this study was to evaluate the therapeutic effect of lycopene on a hyperoxia-induced lung injury model in rat pups. Full-term rat pups were included in the study 12-24 h after delivery. The pups were separated into 4 groups: normoxia control (NC), hyperoxia control (HC), hyperoxia + lycopene (HL), and normoxia lycopene (NL). The normoxia groups were housed in ambient air, and the hyperoxia groups in > 85% O2. HL and NL groups received 50 mg lycopene in oil/kg body weight/day delivered intraperitoneally (i.p.), the other groups received oil alone. On day 11, the rat pups were sacrificed and their lungs removed. Statistically significant injury was observed in all histological parameters measured (MLI, proliferating cell nuclear antigen (PCNA), and apoptosis) in the HC group (HC vs NC, p = 0.001). This injury could not be reversed with lycopene treatment (HC vs HL, 0.05; NC vs HL, p = 0.001). With hyperoxia, statistically significant decreases were observed in biochemical parameters in terms of SOD, MDA, and IL-6 values (HC vs NC: SOD, p = 0.02; MDA, p = 0.043; IL-6, p = 0.001). The use of lycopene did not provide any improvement in these values (HC vs HL, p > 0.05). Hyperoxia or lycopene had no effect on IL-1ß and GPx (p > 0.05). When comparing NC and NL groups, negative effects were observed in the group given lycopene in terms of MLI, PCNA, apoptosis, and IL-6 (all parameters, p = 0.001). We observed that 50 mg lycopene in oil/kg body weight/day given via i.p. had no curative effect on the hyperoxia-induced lung injury in newborn rats and may even induce adverse effects.

RESUMO

BACKGROUND: Extensively resistant Acinetobacter baumannii has emerged and spread worldwide as a significant cause of health care-associated infections and outbreaks. It also causes life-threatening infections among neonates, including bacteremia. The aim of this study was to investigate an outbreak of A baumannii bacteremia (ABB) among neonates. MATERIALS AND METHODS: A retrospective, case-control study was conducted from July 2014 to July 2015 in a neonatal intensive care unit (NICU). Risk factors associated with ABB in univariate and multivariate analysis with logistic regression was performed. Molecular typing by pulsed field gel electrophoresis was used to confirm relatedness of bacteremic A baumannii strains. RESULTS: During the 5-year period (2011-2016), 68 patients in our NICU were diagnosed with BSI due to A baumannii. The case-control study included 41 case patients within the outbreak caused by a major epidemic clone and 108 control patients. Risk factors (by univariate analysis) associated with ABB were intubation, 14-day mortality, and use of peritoneal dialysis and an umbilical catheter. Multivariate analysis identified 14-day mortality (odds ratio, 5.75; 95% confidence interval, 2.58-12.79) and umbilical catheter use (odds ratio, 2.44; 95% confidence interval, 1.1-5.4) as independent risk factors for ABB. CONCLUSIONS: This outbreak of bacteremia due to resistant A baumannii affected 41 infants and was associated with 58% mortality. Control of the outbreak was achieved by implementing long-term sustained infection control measures within the unit.

RESUMO

OBJECTIVE: Cystatin C (CysC) is commonly used as a marker of renal failure in premature infants. The aim of this study was to investigate serum CysC levels in osteopenia of prematurity (OP) and determine whether CysC could be safely used as a marker of renal insufficiency in infants with OP. METHODS: Subjects were 50 preterm infants (≤32 gestational weeks). Calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) serum levels were measured in postnatal week nine, and bone density was measured concurrently by quantitative ultrasonography. Patients with a Z score of <-2 were considered to have OP. RESULTS: The mean serum CysC levels in preterm infants in postnatal week nine were 1.50±0.19 mg/L. Serum CysC levels were not correlated with speed of sound values, Z scores, serum Ca, P or ALP levels. Serum CysC levels were not significantly different between infants with OP [1.50 (1.35-1.61) mg/L] and in infants without OP [1.58 (1.28-1.70) mg/L]. CONCLUSION: The presence of OP does not affect the safety of CysC as a marker of renal insufficiency in preterm infants.

RESUMO

PURPOSE: Retinopathy of prematurity (ROP) is one of the major problems of surviving premature infants with several ophthalmic morbidities such as increased risk of refractive errors, strabismus, and cortical visual impairment. Use of propranolol hydrochloride (PH) for the prevention of ROP is a new promising treatment modality. However, long-term effects are still to be defined. In our study, we aimed to investigate the short-term refractive effects of PH used for ROP prophylaxis in very preterm newborns. METHODS: This is a prospective, randomized, double-blind, placebo-controlled study. Very preterm newborns with a birthweight less than or equal to 1500 g and/or born prior to 32 gestational weeks were included in the study. The subjects were randomly divided into two groups: control group (CG, n = 37) given placebo and PH group (PHG, n = 34) given PH starting from 4 weeks after birth (27.1 ± 2.1 day). PHG patients received PH therapy for about 1 month (25.7 ± 7.8 day). Anthropometric measurements including weight, length, and head circumference were recorded before PH treatment (at birth) and during eye control (at corrected age). Cycloplegic refraction values were measured by retinoscopy at corrected age (CG: 10.3 ± 4.3 months, PHG: 11.4 ± 4.8 months). RESULTS: Anthropometric measurements including gestational age, weight, length, and head circumference were similar at birth and corrected age in both groups. The mean level of spherical refraction was significantly less hyperopic in the PHG than in the CG (CG: 1.37 ± 1.40 D, PHG: 0.37 ± 1.44 D) (p = 0.005). CONCLUSION: PH may lead to myopic shift by affecting the beta-adrenergic receptors in the choroid or ciliary body of the developing eye. Long-term refractive follow-up is required in order to elucidate the effects of PH on emmetropization process of these very preterm infants.

RESUMO

BACKGROUND: Health care programs for children with Down syndrome (DS) help improve the overall outcome and quality of life of these children. It is therefore very important to focus on the most common and serious problems of these patients, such as congenital heart defects and cardiac problems, and to keep medical guidelines updated with regard to these problems. OBJECTIVES: The aim of this study was to evaluate aortic intima-media thickness (aIMT), lipid profiles and blood pressure in DS patients in comparison with a control group of ageand gender-matched neonates without DS. MATERIAL AND METHODS: Serum concentrations of lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglyceride), blood pressure and abdominal aIMT were measured in newborns with DS, and compared with the measurements from ageand gender-matched newborns without DS. RESULTS: No statistically significant differences between the 2 groups of newborns were detected with respect to aIMT, lipid levels or blood pressure. CONCLUSIONS: This study represents the first investigation of aIMT - one of the most important indicators of atherosclerosis - in DS patients, but neither a significantly increased aIMT, nor any significant changes in lipid profiles or blood pressure were detected in this group of patients. Whether aIMT differs according to the type of congenital heart defect (such as atrial septal defect, ventricular septal defect, patent ductus arteriosus, and atrioventricular septal defect) among DS patients remains to be determined in future studies.

RESUMO

OBJECTIVES: To identify endocrinologic problems, particularly those concerning growth, in collodion babies (CBs). METHODS: Clinically identified newborn CBs were included in the study group (group 1). Because CBs are generally born premature, small for gestational age (SGA), or both, a control group matched to the study group in terms of gestational age and birthweight (group 2) was also established. Blood specimens were collected from both groups for thyroid function tests and to measure serum growth hormone (GH), insulinlike growth factor 1 (IGF-1) and IGF binding protein-3 (IGFBP-3) levels. RESULTS: Group 1 consisted of 42 CBs (25 male, 17 female) with gestational ages of 32 to 42 weeks and birthweights of 1,400 to 4,000 g. Twelve were assessed as premature and 17 as SGA. Serum IGF-1 and IGFBP-3 levels were lower and serum GH levels higher than in controls. Primary hypothyroidism was diagnosed in 10 patients in the study group, subclinical hypothyroidism in 2, and central hypothyroidism in 1. A statistically significant difference was determined between the groups in terms of primary hypothyroidism (p = 0.01). Serum GH levels were weakly negatively correlated with birthweight (correlation coefficient [r] = -0.32, p = 0.04) and serum IGF-1 (r = -0.38, p = 0.001) and IGFBP-3 (r = -0.36, p = 0.002) levels. CONCLUSION: Premature birth and SGA are common in CBs. GH levels are high and IGF-1 and IGFBP-3 levels low at birth as a sign of GH resistance in these patients. The greater prevalence of hypothyroidism in these children is also significant.

RESUMO

Hemophagocytic lymphohistiocytosis (HLH) is characterized by activation of cytotoxic T and natural killer (NK) cells, and macrophages related to a spectrum of hyperinflammatory disorders. The clinical findings mainly include high fever, cytopenia, splenomegaly, phagocytosis, and proliferation of histiocytes in lymphoreticular tissue. To the best of our knowledge, transfusion-associated graft versus host disease (TA-GVHD) in a 13-day old male newborn with HLH is being reported first time in the literature. The aim of this report was to emphasize the importance of blood products irradiation in the prevention of the development of graft versus host disease especially among high-risk subjects such as newborns with HLH.

RESUMO

BACKGROUND: Iodine deficiency (ID) during the fetal and neonatal periods can lead to neonatal hypothyroidism. This study was conducted to evaluate the effect of ID on the thyroid hormone level of newborns living in Turkey. METHODS: Between 1998 and 2013, 71 newborns with a urinary iodine concentration <100 µg/L were recruited into the study. Data on thyroid volume, free triiodothyronine (fT3), free thyroxine (fT4), thyroid stimulating hormone (TSH), and thyroglobulin (Tg) were collected from all newborns, and on breast milk iodine from their mothers. Infants who were classified as having congenital hypothyroidism (TSH >40 mU/L and fT4 <8.5 pmol/L) were treated with levothyroxine (n=26, T group), while the remaining infants remained untreated (n=45, UT group). Thyroid hormones were subsequently measured 7-14 days later in a sub-sample of both treated and untreated infants. RESULTS: The average values at the time of admission were as follows [median (min-max)]. fT3: 5.0 (2.8-7.1) pmol/L, fT4: 7.7 (0.13-19.1) pmol/L, TSH: 75 (14-426) mU/L, Tg: 464 (226-1100) ng/mL, urinary iodine concentration (UIC): 30 (0-61) µg/L, breast milk iodine levels: 21 (10-150) µg/L, thyroid ultrasound (USG): 1.10 (0.24-1.95) mL for the T group; and fT3: 5.7 (1.7-12.7) pmol/L, fT4: 16.2 (9.9-33.5) pmol/L, TSH: 5.4 (0.63-41.8) mU/L, Tg: 171 (15-2124) ng/mL, UIC: 39 (0-90) µg/L, breast milk iodine levels: 47 (10-120) µg/L, thyroid USG: 0.75 (0.35-1.72) mL for the UT group. A significant difference was found between groups in respect to fT3, fT4, TSH and Tg levels. No significant difference in thyroid ultrasonography, UIC, and breast milk iodine levels was found between the two groups. The Tg levels of 50 out of 71 patients were measured, 40 (80%) of whom had Tg levels above the normal range (101 ng/mL). CONCLUSIONS: In our country, despite the use of iodized salt, congenital hypothyroidism due to ID remains a problem. The Tg level of newborns can be used as a good indicator of ID.

PURPOSE: Retinopathy of Prematurity (ROP) is a proliferative vitreoretinopathy which is one of the most frequent causes of blindness in children. In an attempt to find a solution to this important problem in preterm children, the search for new, effective treatment modalities with fewer side effects is underway. In our study, which was planned for this reason, we aimed to investigate the effects of propranolol treatment applied to cases of ROP in various stages during the second phase (known as the neovascularization-hypoxia phase) and to determine the correlation of these effects with the platelet mass index (PMI). METHOD: A total of 171 preterm infants at risk of ROP were selected randomly for inclusion in the study. All of the patients were classified according to their stage of ROP and were divided into control and treatment groups. While the cases in the control group were administered physiological saline solution, those in the treatment group were administered propranolol in the period that corresponded to the second stage of the disease. The thrombocyte and PMI values in the first and second stages of each study group were recorded. RESULTS: A significant difference was found between the control and treatment groups of the stage 2 ROP study subjects. In the stage 2 ROP study group, no significant difference was detected between the control and treatment cases in terms of platelet counts in phase 1 or in the PMI values and the thrombolytic counts in phase 2. On the other hand, in phase 2 of the stage 2 ROP study subjects significant differences were detected between the control and treatment group in terms of PMI values. CONCLUSION: In the study, it was found in the stage 2 ROP study group that propranolol reduced the need for laser photocoagulation significantly. Also, in parallel to the efficacy of propranolol in this study group, a decrease was observed in PMI values.

RESUMO

OBJECTIVES: To assess whether TSH and fT4 have a role in the angiogenesis of vaso-obliteration and neovascularization which are the basic pathophysiology of ROP. METHODS: In this retrospective case-control study, the control group (n = 56) included preterm newborns with risk for ROP while the laser group (n = 63) was recruited from cases who developed severe neovascularization and needed laser photocoagulation therapy. Considering the first (vaso-obliteration) and second (neovascularization) phases of the disease, in this study we researched the distribution of thyroid function tests between groups. RESULTS: With regard to the first phase of the disease, TSH and fT4 showed no significant differences between the control and laser groups accordingly (P > 0.05). Likewise, in the second phase of ROP, there was no significant difference between the control and laser groups with respect to TSH and fT4 levels (P > 0.05). CONCLUSION: We found that between the study groups, the levels of thyroid function tests did not have any significant differences, either in the first or the second phases of ROP which are the principal pathophysiology of the disease. Therefore, it was concluded that thyroid hormone values were not informative markers in the course of the disease in preterm babies at risk of developing ROP.

RESUMO

This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications. Administration of corticosteroid, tocolysis for two days and prophylactic antibiotics (intravenous ampicillin/sulbactam, and oral azithromycin) were the standard management protocol. The mean age at PPROM was 29 weeks 2 days (±3 weeks), the mean age at birth was 30 weeks 5 days (±20 days). CRP levels were not different between groups. Uni/multivariate analysis showed that maternal CRP levels were not related with neonatal outcomes. Neonatal complications in PPROM are related with the degree of prematurity and maternal WBC counts.

RESUMO

In spite of advances in neonatal care and the new generation of antibiotics, neonatal sepsis is still a major cause of morbidity and mortality. Early diagnosis of neonatal sepsis is difficult because clinical signs are non-specific. Thus, new biomarkers are still needed for diagnosis. Gelsolin is an actin-binding plasma protein. Furthermore, extracellular gelsolin binds lipopolysaccharide and lipoteichoic acid, which are major virulence factors of Gram-negative and Gram-positive bacteria. The result of this binding is the inhibition of gelsolin's F-actin depolymerizing activity. Thus, gelsolin inhibits the release of IL-8 from human neutrophils subjected to lipoteichoic acid, lipopolysaccharide and heat-inactivated bacteria treatment. Our hypothesis is that pGSN levels decrease in neonatal infants with sepsis and this decrease might be used as a reliable biological marker. Forty patients who were diagnosed with severe sepsis at a neonatal intensive care unit were enrolled in the sepsis group. Twenty patients who were followed for prematurity were enrolled in the control group. The pGSN level at the time of diagnosis in the sepsis group was 33.98±11.44µg/ml, which was significantly lower than that of control group (60.05±11.3µg/ml, P<0.001) and after treatment (53.38±31.26µg/ml, P=0.003). Area under ROC curve was 0.96 (p: 0.0001, 95% CI; 0.90-0.99). Sensitivity was 90.32 (95% CI; 74.2-97.8), specificity was 95 (95% CI; 75.1-99.2). Plasma gelsolin significantly decreased in septic patient and recovery of decreased gelsolin levels correlated with clinical improvement. Thus, plasma gelsolin may be a usable marker for severe sepsis.
