NEFROPATIILE TOXICE IN INTOXICATIILE ACUTE LA COPIL SI ADOLESCENT – PREVALENTA, CAUZE SI FACTORI DE RISC

REZUMAT

Obiective. Incidenţa şi prevalenţa reală a afectării renale în cadrul intoxicaţiilor copilului nu este pe deplin cunoscută, modificările funcţionale şi structurale renale cauzate de nefrotoxine sunt nespecifice şi de multe ori etiologia toxică este trecută în plan secund. Studiul de faţă îşi propune evaluarea prevalenţei nefropatiilor toxice la copii spitalizaţi pentru intoxicaţii acute, etiologia, aspectele clinice şi paraclinice, factorii de prognostic pozitiv sau negativ, frecvenţa folosirii tehnicilor de epurare extrarenală şi impactul acestora asupra supravieţuirii.

Material şi metodă. Am realizat un studiu observaţional, retrospectiv, bicentric pe o perioadă de 10 ani, pe un lot ce a cuprins 82 de pacienţi între 0-18 ani din două centre antitoxice pediatrice: în cadrul secţiei de Toxicologie a SCUC „Grigore Alexandrescu“, Bucureşti şi în cadrul secţiei de Nefrologie şi Toxicologie Pediatrică din cadrul Spitalului Clinic de Urgenţă de Copii din Cluj-Napoca. În lotul de studiu au fost incluşi pacienţi cu intoxicaţie acută ce au prezentat în evoluţie injurie renală acută definită după criteriile AKIN.

Rezultate. Prevalenţa injuriei renale acute toxice a fost de 1%. Etiologia acesteia este dominată de medicamente – 36,6% urmate de ciuperci – 24,4%, insecticide – 18,3% şi alcooli cu 11%. În procente mult mai mici au fost implicate substanţele caustice, hidrocarburile, substanţele methemoglobinizante şi plumbul. În grupul intoxicaţiilor medicamentoase au predominat intoxicaţiile plurimedicamentoase, urmate de intoxicaţiile cu antibiotice, cel mai frecvent fiind implicată gentamicina. În cazul intoxicaţiilor plurimedicamentoase substanţele cel mai frecvent implicate au fost: combinaţii de AINS cu Paracetamol şi Metamizol. În cadrul intoxicaţiilor cu ciuperci în majoritatea cazurilor au fost implicate ciupercile cu durată de incubaţie lungă, cel mai probabil Amanita Phalloides. Etiologia intoxicaţiilor cu alcooli a cuprins cel mai frecvent etilenglicolul. În intoxicaţiile cu insecticide etiologia a fost reprezentată mai ales de către insecticidele organofosforice şi carbamate. Pe lotul studiat de 82 de cazuri, s-au înregistrat 26 de decese, mortalitatea a fost de 32%. Au reprezentat factori de risc pentru deces următorii: oliguria, anuria, edemele, manifestările hemoragice, polipneea, semnele de şoc, coma, hepatocitoliza şi insuficienţa hepatică. Metodele de epurare extrarenală sau substituţie renală au fost aplicate în 41% din cazuri. Ele nu au reprezentat factori de protecţie pe lotul studiat.

Concluzii. Intoxicaţiile acute la copil înregistrează o creştere importantă în ultimii ani în toată ţara. Cazurile cu injurie renală acută toxică au un prognostic de multe ori rezervat, astfel că acestea, precum şi factorii de risc asociaţi trebuie identificate şi diagnosticate rapid în vederea instituirii unui tratament ierarhizat precoce şi eficient.

ACUTE KIDNEY INJURY IN CHILDREN AND ADOLESCENT POISONING – PREVALENCE, ETIOLOGY AND RISK FACTORS

Alexandru-Ioan Ulmeanu, Aurel Bizo and Coriolan Ulmeanu

ABSTRACT

Objectives. The incidence and prevalence of renal disease in actual children poisoning is not fully known because renal structural and functional changes caused by nephrotoxins are nonspecific and toxic etiology is often overshadowed. This study aims to assess the prevalence of toxic nephropathies in a pediatric population, the etiology, clinical and laboratory aspects, prognostic factors, frequency of use of extra renale puration techniques and their impact on survival.

Materials and methods. We conducted an observational, retrospective, multicentric study, over a period of 10 years, between 2003 and 2012, on 82 patients aged 0-18 years from two pediatric poison centers: the department of Toxicology SCUC “Grigore Alexandrescu” Bucharest and the Department of Pediatric Nephrology and Toxicology at the Emergency Clinical Hospital for Children in Cluj-Napoca. In the study group were included patients with acute intoxication who presented acute kidney injury defined by the AKIN criteria.

Results. The etiology of poisoning that have associated acute kidney injury is dominated by drugs – 36.6%, followed by mushrooms – 24,4%, insecticides – 18.3% and alcohols – 11%. In smaller percentages we noted poisonings with caustic substances, hydrocarbons, nitrites and lead. Looking in detail we can observe that for the etiology of drug poisonings multidrug intoxications prevailed followed by poisonings with antibiotics most commonly gentamicin. In the case of multi drug poison ings the substances most frequently involved were: combination of Paracetamol, NSAIDs andMetamizol.In mushroom poisonings, in most cases were involved mushrooms with long incubation period probably Amanita Phalloides. For the Insecticide poisonings the etiology was represented mainly by organophosphorus and carbamate insecticides. The etiology of alcohol poisoning most commonly included cases of ethylenglycol. On the group of 82 cases studied, 26 deaths were recorded, mortality was 32%. We observed that oliguria, anuria, edema, hemorrhagic manifestations, polypnea, signs of shock, coma, and hepatic hepatocytolisis were risk factors for death in our study. The methods of extrarenal epuration or renal replacement treatment were carried out in 41% of cases. They were not protective factors in the study group.

Conclusions. Acute poisoning cases in children show asignificant increasein recent years in our country. The cases oftoxic acute renal injury often have severe prognosis. Associated risk factorsshould be identified and diagnosed quickly to establish aprioritized early and effective treatment.

REZUMAT

Introducere. Pneumonia comunitară reprezintă una din cauzele principale de deces în lume la copii cu vârsta sub 5 ani. Detecţia virală prin PCR multiplex este din ce în ce mai utilizată în practică, ea este utilă pentru a înţelege epidemiologia şi impactul virusurilor asupra populaţiei pediatrice însă există în continuare multe discuţii legate de cum influenţează detecţia virală modul efectiv de îngrijire al pacientului.

Obiective. În studiul efectuat ne-am propus analiza impactului pe care l-a avut identificarea etiologiei virale asupra duratei spitalizării şi asupra tratamentului administrat pe parcursul internării în spital.

Material şi metodă. Am efectuat un studiu retrospectiv pe o perioadă de 4 ani, au fost selectaţi copii între 0-5 ani cu infecţie severă de tract respirator inferior. Am comparat 3 grupuri: un grup cu infecţie virală specificată, un grup cu infecţie virală nespecificată şi un grup cu infecţie bacteriană.

Rezultate. În perioada analizată 72 de copii ce au prezentat semne de insuficienţă respiratorie acută au avut stabilit un diagnostic etiologic concret de infecţie virala, doar 2% din totalul infecţiilor virale diagnosticate în spital. Etiologia principală a fost reprezentată de virusul sinciţial respirator (VSR) în 73,5% dintre cazuri, urmat de Influenza cu 11%, Parainfluenza cu 4,2%, Metapneumovirusul (HMPV), Rinovirus, Bocavirus şi Adenovirus toate cu 2,8%. În cadrul infecţiei virale nespecifi cate s-au folosit antibiotice în 85,5% (n = 53) dintre cazuri. În cadrul infecţiei virale specificate deşi etiologia virală a fost certă, rata de folosire a antibioticelor a fost mai ridicată de 92% (n = 57) Durata spitalizării a fost în medie de cu 2,5 zile mai lungă în cadrul lotului cu infecţie virală specificată, faţă de lotul cu infecţie virală nespecifi cată. Deşi diagnosticul de infecţie virală a fost cert, dat fiind tabloul clinic sever şi vârsta mica a copiilor cheltuielile realizate pentru cei cu infecţie virală specificată au fost cu 30% mai mari faţă de cei cu infecţie virală nespecificată.

Concluzii. În studiul efectuat VSR este virusul cel mai frecvent implicat în etiologia ITRI virale, fiind implicat în forme severe de boală mai ales la sugarii mici şi foştii prematuri. Antibioterapia este utilizată în mod frecvent în formele severe de ITRI, chiar dacă etiologia virală este certă şi cunoscută, clasele de antibiotice folosite fiind asemănătoare. Determinarea etiologiei virale nu a redus spitalizarea, şi nici nu a dus la schimbarea atitudinii terapeutice a medicului curant.

THE IMPORTANCE OF VIRAL ETIOLOGY DETERMINATION IN SEVERE LOWER RESPIRATORY TRACT INFECTIONS IN INFANTS AND CHILDREN

Alexandru-Ioan Ulmeanu, Carmen Zapucioiu, Maria Dorina Craciun and Coriolan Ulmeanu

ABSTRACT

Introduction. Community-acquired pneumonia is one of the leading causes of death worldwide in children under 5 years. In practice, viral detection using multiplex PCR is becoming increasingly used, it is most useful to understand the epidemiology and impact of viruses on the pediatric population but there are still many debates regarding the influence of viral detection on patient care.

Objectives. In this study we aimed to analyze the impact of viral etiology determination on the duration of hospitalization and on the administered treatment.

Material and methods. The selection criteria was: children between 0-5 years with severe lower respiratory tract infection. We have analyzed three groups of patients: a group with specified viral infection, a second group with unspecified viral infection and a third group with bacterial infection.

Results. In the analyzed period 72 children under 5 years of age who have shown signs of acute respiratory failure have been diagnosed with a specifi c viral infection, only 2% of the total viral infections. The main etiology was represented by respiratory syncytial virus (RSV) in 73.5% of cases, followed by Influenza 11%, Parainfluenza 4.2%, metapneumovirus (hMPV), Rhinovirus, Adenovirus and Bocavirus all with 2.8%. Within the unspecified viral infection group antibiotics were used in 85.5% (n = 53) of the cases. Within the specified viral infection group although viral etiology was firmly established antibiotics usage rate was higher 92% (n = 57). Duration of hospital stay was 2,5 days higher in the viral specified group compared with the unspecified one. Thus we found that although the diagnosis of viral infection was certainly given because of severe clinical picture and young age of children the expenses were 30% higher.

Conclusions. In our study, RSV is the most common virus involved in the etiology of viral LRTI and is encountered in the most severe forms of the disease especially in young infants and prematures. Antibiotics are commonly used in the severe forms of LRTI, even if the viral etiology is certain and the groups of antibiotics used are similar. Determination of viral etiology has not reduced hospitalization, nor has led to changing of physician therapeutic approach.

REZUMAT

Metoda de investigaţie standard în cazul suspiciunii unui reflux gastroesofagian este reprezentată de pH-metria esofagiană. Cu toate acestea, marea majoritate a episoadelor de reflux la sugari şi copii sunt slab-acide (pH>4), iar simptomele extradigestive pot fi declanşate de către episoade de reflux atât acid, cât şi slab-acid. Pentru a depăşi aceste aspecte, o nouă metodă a fost dezvoltată în ulltimii douăzeci de ani şi supusă evaluării ştiinţifice: impedanţa esofagiană. În combinaţie cu pH-metria esofagiană standard, aceasta aduce mult mai multe informaţii decât simpla pH-metrie, deoarece permite analiza refluxului non-acid şi a asocierii temporale dintre acesta şi simptome. Informaţia analizată precizează compoziţia bolusului (gaz, fluid, solid), înălţimea, du rata refluxului şi timpul de clearance al bolusului. Deşi nu sunt încă disponibile valori pentru limitele normalului în populaţia pediatrică, impedanţ-pH-metria promite să devină noul gold-standard în investigarea refluxului gastroesofagian.

PRINCIPLES OF COMBINED ESOPHAGEAL IMPEDANCE-PH MONITORING IN CHILDREN: INDICATIONS, BENEFITS AND LIMITATIONS

Mihai-Mirel Stoicescu, Felicia Galos, Mihai Munteanu, Simina Visan, Coriolan Ulmeanu and Mihaela Balgradean

ABSTRACT

The standard test for suspected gastroesophageal reflux is pH monitoring. However, the majority of gastroesophageal reflux episodes in infants and children are nonacidic (pH > 4) and extraesophageal symptoms apparently can be caused by both acidic (pH < 4) and nonacidic reflux. In order to overcome these aspects, a new technique has been developed and placed under scrutiny in the past twenty years: multichannel intraluminal impedance. Combined with standard pH recording, it provides more information than simple pH measurement because it allows the study of non-acid reflux and the temporal association between symptoms and nonacid reflux. Data can be analyzed for bolus composition (gas, fluid, solid) and reflux height, duration, and clearance. Although normal values for the pediatric population are not yet available, combined multichannel intraluminal impedance and pH measurement has the potential to become the new “gold standard” for gastroesophageal reflux testing
