Table of Contents
Che cos’è la leishmaniosi ?
Il termineleishmaniosisi riferisce a uno spettro di malattie infettive provocate da protozoi emoflegellati del genereLeishmaniatrasmesse all’uomo da un insetto vettore (il flebotomo) che si possono presentare con manifestazioni cutanee (leishmaniosi cutanea), mucose (leishmaniosi mucosa) o viscerali (leishmaniosi viscerale). Nella patogenesi delle infezioni daleishmaniaqualunque sia la specie coinvolta o lo spettro clinico determinato, un ruolo importante è sostenuto dallarisposta immunitaria dell’ospite, e soprattutto dalla sua componente cellulo-mediata.
Leishmaniosi viscerale
Nella leishmaniosi viscerale l’incubazione è in genere lunga (2-6 mesi)e la lesione in sede di inoculazione è di solito assente. L’esordio è raramente acuto, diversamente da quanto avviene per altre cause di febbre da emoparassiti, come la malaria, ed è spesso caratterizzato da febbricola intermittente.
La fase di stato della malattia è caratterizzata soprattutto da:
- Febbre intermittente o continuo-remittente(non sempre con i caratteristici due picchi giornalieri)
- Astenia ingravescente
- Dimagrimento progressivo, che può eventualmente evolvere fino alla cachessia
- Emorragie(frequenti l’epistassi e le gengivorragie)
- Dolori addominali
- Epigastralgie
- Tosse
- Diarrea e/o dissenteria
- Altralgie diffuse.
L’esame obiettivo evidenzia unasplenomegalia dura, indolente,epatomegalia,linfoadenomegaliaed eventuale ittero. Nelle persone con infezione daHIVsi osserva spesso una diffusione sistemica degliamastigoti di Leishmaniache possono essere ritrovati, oltre che nelle sedi tipiche (midollo osseo, fegato, milza) anche a livello polmonare, pleurico, gastroenterico, urogenitale e cutaneo.
Leishmaniosi cutanea
Laleishmaniosicutanea è conosciuta anche comebottone l’Orienteo bottone tropicale, foruncolo di Delhi o di AleppoUta o piaga del chiclero o framboesia della foresta.
Le principali specie causali sono:
L. major e L. tropica:Europa meridionale, Asia e Africa.
L. mexicana:Messico e America centrale e meridionale.
L. braziliensis:America centrale e meridionale.
Il cane e i roditori costituiscono l’habitat del parassita che è trasmesso da unflebotoma(Phlebotomus papatasi). La trasmissione interumana è possibile dal contatto diretto della pelle graffiata con le lesioni di un malato. L’epidemiologia dipende dalla presenza del flebotoma e comprende le rive del Mediterraneo, del Mar Caspio, il Medi Oriente, l’India, Africa orientale e centrale.
Sintomi
Forma cutanea (L. tropica): il periodo di incubazione dura da 2 a 8 settimane; nel punto della puntura del flebotoma, si ha uneritemaseguito da unapapulache dopo alcuni giorni si trasforma in unnodulo sopraelevato, rosso, che si copre di squame bianche.La lesione può regredire a questo stadio o evolvere verso un’ulcerazione di alcuni centimetri di diametro, diventando sempre più profonda e circondata da uneritema o da un edema. L’evoluzione è lenta e l’ulcera può persistere per diversi mesi prima di guarire lasciando una cicatrice escavata.
Forma muco-cutanea (L. braziliensis)
Nella leishmaniosi muco-cutanea, la lesione cutanea è complicata da ulcere torbide delle mucose naso-faringee (espundia) che spesso si sovrainfettano. Successivamente, mesi o anni più tardi, compaiono le tipiche lesioni mucose, che talvolta possono comportare estese mutilazioni del naso e del palato.
Diagnosi
Nellaleishmaniosi visceralesi osserva con una certa frequenza una pancitopenia o soltanto un quadro di anemia normocromica, piuttosto che di leucopenia con spiccata neutropenia o piastrinopenia; la PCR è solitamente elevata e caratteristiche è ladisprotidemia.
Nellaleishmaniosicutaneasi osservano raramente alterazioni dei comuni esami di laboratorio.
La forma cutaneo-mucosa, nella sua fase di invasione delle mucose, è spesso accompagnata da segni indiretti di infiammazione.
Decorso e prognosi
Di solaleishmaniosivisceraleraramente si muore, ma le complicanze sono numerose e spesso fatali:
- Progressivo decadimento dello stato generale
- Aplasia midollare
- Dissenteria
- Compromissione cardiaca e renale
- Edemi
- Ascite
- Morte per infezioni o complicanze intercorrenti.
Le più frequenti sono rappresentate da infezioni broncopolmonari (polmonite pneumococcica,tubercolosi),sepsiinfezioni del tratto gastroenterico (amebiasi, sighellosi ecc..). Fortemente invalidanti sono altre complicanze, come le emorragie retiniche.
Il decorso dellaleishmaniosicutaneaè di solito benigno; dopo un periodo variabile da alcuni mesi fino al massimo di un anno, l’ulcera guarisce lasciando una cicatrice piatta, atrofica e depigmentata. Rare sono le forme recidivanti a distanza di anni e ancora più raro è l’interessamento mucoso.
La formacutaneo-mucosa è fortemente invalidanteperla sede delle lesioni mucose; può essere anche fatale per la possibilità di determinare ostruzioni progressive delle vi aeree superiori e polmonitiab ingestis.
Terapia
Il trattamento locale (attraverso l’uso di creme o iniezioni cutanee) è indicato per le forme cutanee con piccole lesioni non complicate.
Per il trattamento della leishmaniosi viscerale è indicata:
- Amfotericina B liposomialeper via orale o parenterale (rientra spesso nella terapia della forma mucocutanea e della forma viscerale); scarsi effeeti secondari: ipertermia, brividi, reazioni allergiche. Costo elevato, sostenibile solo in Paesi con adeguate risorse economiche.
- Antifungini azolicicome, ad esempio, fluconazolo, itraconazolo, ecc.
- Paromomicina per via orale;
- Pentamidina per via parentarale (utilizzata nella leishmaniosi cutanea e viscerale).

In the earliest Greek inscriptions dating to the 8th century BC following
the Greek Dark Ages, the letter rests upon its side. Its name in most
other languages matches the letter’s pronunciation in open syllables.
Learn a new word every day. In the King James Version of
the Old Testament and occasionally in writing and speech an is used before h in a stressed syllable.
Before unstressed or weakly stressed syllables with initial
h both a and an are used in writing.
A is the letter that was used to represent a team in an old TV
show, The A-Team. In musical notation, the letter A is the
symbol of a note in the scale, below B and above G. That is not surprising,
because it means the same sound. To add A, a to a word list please sign up or log in. There are also precomposed character encodings for ⟨A⟩ and ⟨a⟩
with diacritics, for most of those listed above; the remainder are produced using combining diacritics.
The double ⟨aa⟩ sequence does not occur in native English words, but is found in some words derived
from foreign languages such as Aaron and aardvark.
