Limfadenitis mezenterialny
Patofizjologia i mechanizm
Limfadenitis mezenterialny to zapalenie węzłów chłonnych krezki jelita, najczęściej lokalizujące się w prawym dolnym kwadrancie jamy brzusznej, w okolicy końcowego odcinka jelita krętego. Patogeneza obejmuje penetrację patogenów (wirusów, bakterii) przez ścianę jelita do układu limfatycznego, z namnażaniem się w węzłach chłonnych i wywołaniem stanu zapalnego, który może prowadzić do ropienia. Diagnostycznie ultrasonografia wykazuje powiększone węzły chłonne o wymiarze ≥8 mm w osi krótkiej lub skupisko ≥3 węzłów >5 mm. W patogenezie kluczowe są szlaki sygnałowe NF-κB, TNF oraz AGE-RAGE, które indukują produkcję cytokin prozapalnych (np. TNF-α, IL-1, IL-2, IFN), co manifestuje się bólem brzucha i gorączką. Etiologia obejmuje infekcje wirusowe (rotawirusy, adenowirusy, EBV, Coxsackie, rubeola) oraz bakteryjne (Yersinia enterocolitica, Streptococcus, Staphylococcus, E. coli, Mycobacterium tuberculosis, Salmonella), a także choroby zapalne jelit, chłoniaki i inne schorzenia układu immunologicznego.

Patogeneza i mechanizm limfadenitis mezenterialny
Limfadenitis mezenterialny (inaczej zapalenie węzłów chłonnych krezki) to stan zapalny węzłów chłonnych zlokalizowanych w krezce jelita, czyli błonie łączącej jelito ze ścianą jamy brzusznej. Schorzenie to charakteryzuje się obrzękiem i stanem zapalnym węzłów chłonnych, najczęściej w prawym dolnym kwadrancie jamy brzusznej, w okolicy końcowego odcinka jelita krętego.12
Mechanizm infekcji i zapalenia
Proces patogenetyczny limfadenitis mezenterialny przebiega w charakterystyczny sposób. Czynniki patogenne (wirusy, bakterie) dostają się do organizmu drogą pokarmową i penetrują ścianę jelita, przez co uzyskują dostęp do układu limfatycznego jelita. Mikroorganizmy chorobotwórcze przedostają się następnie do węzłów chłonnych krezki za pośrednictwem naczyń limfatycznych.34
Po przedostaniu się do węzłów chłonnych patogeny namnażają się i, w zależności od swojej zjadliwości, wywołują różne stopnie zapalenia, czasami prowadząc nawet do ropienia. Proces ten często rozpoczyna się w tkance limfatycznej związanej z błoną śluzową jelita, szczególnie w kępkach Peyera, skąd zakażenie rozprzestrzenia się regionalnie poprzez drogi limfatyczne do węzłów chłonnych krezki.56
Zmiany morfologiczne w węzłach chłonnych
Makroskopowo węzły chłonne w limfadenitis mezenterialny są powiększone i często miękkie. Krezka sąsiadująca z zajętymi węzłami może być obrzęknięta, z wysiękiem lub bez. Jeśli obecne jest pierwotne źródło zakażenia (np. zapalenie wyrostka robaczkowego), mogą być widoczne oznaki zapalenia otaczających tkanek.78
Mikroskopowo węzły chłonne wykazują niespecyficzny przerost, a w przypadku infekcji ropnej widoczna jest martwica z licznymi komórkami ropy. Badania histopatologiczne zazwyczaj wykazują zmiany reaktywne w węzłach chłonnych bez specyficznych cech dla konkretnego patogenu, co utrudnia identyfikację czynnika wywołującego na podstawie samej morfologii usuniętych węzłów.910
Pierwotne i wtórne limfadenitis mezenterialny
Limfadenitis mezenterialny można sklasyfikować jako pierwotny lub wtórny:1112
- Pierwotne limfadenitis mezenterialny – występuje gdy nie można zidentyfikować konkretnej przyczyny zapalenia węzłów chłonnych. Jest to idiopatyczna limfadenopatia krezki, najczęściej zlokalizowana po prawej stronie, w pobliżu końcowego odcinka jelita krętego, bez uchwytnej ostrej przyczyny zapalnej.
- Wtórne limfadenitis mezenterialny – związane jest z możliwą do zidentyfikowania przyczyną zapalną w jamie brzusznej, taką jak zakażenie bakteryjne, wirusowe, choroba zapalna jelit czy chłoniak.
Czynniki etiologiczne limfadenitis mezenterialny
Istnieje szereg czynników, które mogą prowadzić do rozwoju limfadenitis mezenterialny. Najczęstszą przyczyną są zakażenia, ale rozwinąć się może również na skutek innych procesów chorobowych.1516
Infekcje wirusowe
Infekcje wirusowe są najczęstszą przyczyną limfadenitis mezenterialny. Do głównych wirusów odpowiedzialnych za to schorzenie należą:1718
- Wirusy wywołujące zapalenie żołądka i jelit (gastroenteritis)
- Rotawirusy
- Adenowirusy
- Wirus Epsteina-Barr (EBV)
- Wirusy Coxsackie
- Wirus odry (Rubeola)
Infekcje bakteryjne
Zakażenia bakteryjne również mogą prowadzić do limfadenitis mezenterialny. Wśród najważniejszych patogenów bakteryjnych wymienia się:2122
- Yersinia enterocolitica i Yersinia pseudotuberculosis – uważane za najczęstsze bakteryjne przyczyny limfadenitis mezenterialny w strefach umiarkowanych Europy, Ameryki Północnej i Australii
- Streptococcus (w tym paciorkowce beta-hemolizujące)
- Staphylococcus
- Escherichia coli
- Mycobacterium tuberculosis
- Salmonella
Bakterie Yersinia enterocolitica są szczególnie istotne w epidemiologii limfadenitis mezenterialny. Zakażenie tą bakterią najczęściej wynika ze spożycia niedogotowanego mięsa (zwłaszcza wieprzowiny) lub zakażonej wody. Bakterie te mogą powodować objawy przypominające ostre zapalenie wyrostka robaczkowego, zaburzenia żołądkowo-jelitowe i zapalenie węzłów chłonnych krezki.2627
Inne przyczyny
Oprócz zakażeń, limfadenitis mezenterialny może być związane z innymi schorzeniami:2829
- Choroby zapalne jelit – takie jak choroba Leśniowskiego-Crohna czy wrzodziejące zapalenie jelita grubego
- Chłoniak – pewne podtypy chłoniaków (nowotworów układu limfatycznego) mogą wpływać na węzły chłonne krezki i powodować limfadenitis
- Choroby tkanki łącznej – takie jak toczeń, stwardnienie, czy reumatoidalne zapalenie stawów
- Zapalenie wyrostka robaczkowego – może prowadzić do wtórnego powiększenia węzłów chłonnych krezki
- Infekcje pasożytnicze – np. Giardia lamblia
- Reakcje nadwrażliwości na obce białka
Patofizjologia zapalenia węzłów chłonnych krezki
Rola układu limfatycznego w patogenezie
Układ limfatyczny odgrywa kluczową rolę w patogenezie limfadenitis mezenterialny. Węzły chłonne są częścią układu odpornościowego i pomagają w filtrowaniu obcych substancji, w tym patogenów. Gdy mikroorganizmy, takie jak bakterie lub wirusy, dostają się do organizmu, węzły chłonne zatrzymują je i próbują je zniszczyć, co prowadzi do ich powiększenia i stanu zapalnego.3334
W przypadku limfadenitis mezenterialny, zapalenie dotyczy węzłów chłonnych zlokalizowanych w krezce jelita, zwłaszcza w okolicy końcowego odcinka jelita krętego. Te węzły chłonne odpowiadają za drenaż limfatyczny z obszaru krętniczo-kątniczego jelita.35
Sekwencja zdarzeń patofizjologicznych
Sekwencja zdarzeń patofizjologicznych w limfadenitis mezenterialny przebiega następująco:36
- Patogen (bakteria/wirus) zostaje spożyty doustnie
- Patogen przenika przez nabłonek jelitowy i dostaje się do krwiobiegu
- Mikroorganizm lokalizuje się w tkance limfatycznej otaczającej błonę śluzową jelita (często w kępkach Peyera)
- Z tego miejsca patogen rozprzestrzenia się regionalnie przez drogi limfatyczne do węzłów chłonnych krezki
- W węzłach chłonnych dochodzi do namnażania się patogenu i reakcji zapalnej
- Węzły chłonne powiększają się i stają się bolesne, co prowadzi do objawów klinicznych
Reakcja zapalna i odpowiedź immunologiczna
Podczas zakażenia liczba białych krwinek wzrasta, a węzły chłonne powiększają się i stają się bolesne. Węzły chłonne znajdujące się najbliżej miejsca zakażenia są zazwyczaj najbardziej dotknięte tym procesem.39
Na poziomie molekularnym, w patogenezie limfadenitis mezenterialny zaangażowane są różne szlaki sygnałowe, w tym:40
- Szlak sygnałowy NF-κB – ważny szlak mediujący odpowiedź zapalną, który może powodować ekspresję czynników zapalnych takich jak TNF-α i IL-1, prowadząc do serii niespecyficznych reakcji zapalnych powodujących nawracający ból brzucha i gorączkę
- Szlak sygnałowy TNF – istotny szlak zaangażowany w ogólnoustrojową odpowiedź zapalną
- Szlak sygnałowy AGE-RAGE (zaawansowane produkty glikacji – receptor dla zaawansowanych produktów glikacji)
Procesy zapalne mogą prowadzić do zwiększonej produkcji cytokin prozapalnych, takich jak interleukina-2 (IL-2) i interferon (IFN), co wzmacnia funkcję immunologiczną i efekt przeciwzapalny.42
Potencjalne powikłania
Limfadenitis mezenterialny zazwyczaj jest schorzeniem samoograniczającym się, ale w niektórych przypadkach może prowadzić do powikłań:4344
- Przedłużające się powiększenie węzłów chłonnych może wskazywać na ciężkie zakażenie bakteryjne, które może rozprzestrzenić się do krwiobiegu i spowodować sepsę
- W rzadkich przypadkach powiększone węzły chłonne krezki mogą spowodować zaburzenia naczyniowe prowadzące do niedokrwiennego zapalenia okrężnicy
- Zakażenie może przekształcić się w ogólnoustrojową odpowiedź zapalną (SIRS), szczególnie u dzieci i pacjentów z obniżoną odpornością
Interesującym odkryciem jest to, że osoby, które przeszły limfadenitis mezenterialny w dzieciństwie, mają znacząco zmniejszone ryzyko rozwoju wrzodziejącego zapalenia jelita grubego w późniejszym życiu, co sugeruje pewien ochronny efekt tego stanu zapalnego przeciwko niektórym chorobom autoimmunologicznym.4748
Diagnostyka i implikacje terapeutyczne
Metody diagnostyczne
Złotym standardem diagnostycznym w limfadenitis mezenterialny jest ultrasonografia jamy brzusznej. W badaniu ultrasonograficznym za diagnostyczne uznaje się obecność co najmniej jednego nieprawidłowo powiększonego węzła chłonnego o wymiarze co najmniej 8 mm w osi krótkiej lub skupisko trzech lub więcej węzłów chłonnych o rozmiarze przekraczającym 5 mm.4950
Badania obrazowe mogą również wykazać pogrubienie ściany jelita oraz powiększone węzły chłonne. Warto jednak zauważyć, że nie istnieje standaryzowany przedział referencyjny dla rozmiaru węzłów chłonnych krezki u bezobjawowych dzieci, a kryterium diagnostyczne obecnie stosowane dla powiększenia węzłów chłonnych krezki było przedmiotem kontrowersji.5152
Implikacje terapeutyczne wynikające z patogenezy
Zrozumienie patogenezy i mechanizmu limfadenitis mezenterialny ma istotne implikacje dla leczenia tego schorzenia:5354
- Ostre limfadenitis mezenterialny jest zazwyczaj samoograniczające się i ustępuje bez leczenia w ciągu 1-4 tygodni
- Leczenie objawowe może obejmować leki przeciwgorączkowe i przeciwbólowe
- Odpoczynek, nawodnienie i ciepło aplikowane na brzuch mogą pomóc złagodzić objawy
- W przypadku ciężkiego zakażenia bakteryjnego mogą być konieczne antybiotyki, aby zapobiec powikłaniom, takim jak posocznica (septicemia)
- Terapia powinna być ukierunkowana na przyczynę zapalenia, jeśli jest ona znana
Na podstawie zrozumienia mechanizmów patogenetycznych, w tradycyjnej medycynie chińskiej stosuje się pary ziół, takie jak Ginseng-Gegen (Panax Ginseng-Radix Puerariae), które działają przeciwzapalnie i przeciw stresowi oksydacyjnemu, co może stanowić potencjalny mechanizm leczenia limfadenitis mezenterialny.5758
Zalecenia dietetyczne wynikające z patofizjologii
Zalecenia dietetyczne dla pacjentów z limfadenitis mezenterialny są oparte na zrozumieniu patofizjologii tego schorzenia:59
- Należy spożywać łatwo strawne pokarmy, pić dużo wody i wybierać niektóre płynne pokarmy
- Zalecane są tosty, banany, krakersy, gotowane warzywa, gotowane ziemniaki i kurczak
- Należy unikać ciężkich, przyprawionych przekąsek lub pikantnych potraw
- Najlepiej unikać mleka i produktów mlecznych przez kilka dni, aby dać żołądkowi odpoczynek, ponieważ produkty te mogą podrażniać żołądek
Zalecenia te mają na celu zmniejszenie obciążenia układu pokarmowego i złagodzenie procesów zapalnych w obszarze jelit i węzłów chłonnych krezki.

Mesenteric adenitis is a syndrome characterized by right lower quadrant pain secondary to an inflammatory condition of mesenteric lymph nodes. […] The etiologies of mesenteric adenitis include several causes of inflammatory response within mesenteric lymph nodes. These include viral infections, bacterial infections, inflammatory bowel disease, or lymphoma. […] Primary mesenteric adenitis is most commonly lymphadenopathy in the mesentery near the terminal ileum without a discoverable underlying cause for the inflammation. Mesenteric adenitis also presents secondary to bacterial or viral gastroenteritis. The pathophysiology for such infection to occur takes place as follows: The bacteria/virus is ingested orally and able to enter the body’s bloodstream via invasion through the intestinal epithelium. The organism then localizes to the nodal lymph tissue of the body surrounding intestinal mucosa; this commonly occurs in Peyer’s patches. From there, the organism can spread regionally through lymphatic pathways to mesenteric lymph nodes resulting in mesenteric adenitis.

Mesenteric lymphadenitis is swelling of the lymph nodes in the mesentery. […] An infection in the intestines, such as a virus, is the usual cause of mesenteric lymphadenitis. […] The most common cause of mesenteric lymphadenitis is a viral infection, such as gastroenteritis. Gastroenteritis is often called stomach flu. This infection causes inflammation and swelling in the lymph nodes in the thin tissue that attaches the intestine to the back of the wall around the stomach area, called mesentery. […] Other causes of mesenteric lymphadenitis include bacterial infection, inflammatory bowel disease and lymphoma. […] Any infection that causes inflammation and swelling in the lymph nodes in the tissue that attaches the bowel to the abdominal wall increases the risk of mesenteric lymphadenitis.

Microbial agents are thought to gain access to the lymph nodes via the intestinal lymphatics. Organisms subsequently multiply and, depending on the virulence of the invading pathogen, elicit varying degrees of inflammation and, occasionally, suppuration. […] Grossly, the lymph nodes are enlarged and often soft. The adjourning mesentery may be edematous, with or without exudates. If a contiguous primary source of infection (eg, the appendix) is present, evidence of inflammation is often apparent. […] Microscopically, the lymph nodes show nonspecific hyperplasia and, in suppurative infection, necrosis with numerous pus cells.

Mesenteric lymphadenitis refers to inflammation of the mesenteric lymph nodes. This process may be acute or chronic, depending on the causative agent. It causes a clinical presentation that is often difficult to differentiate from acute appendicitis. […] The frequent association of this condition, especially in children with upper respiratory tract infection, has popularized a theory that swallowed pathogen-laden sputum may be the primary source of infection. Fecal-oral transmission occurs in Y enterocolitica infection and may present as a common source outbreak. This infection has also been associated with meat, milk, and water contamination. Rarely, person-to-person or zoonotic contacts with fecal carriers can lead to infection. […] Microbial agents are thought to gain access to the lymph nodes via the intestinal lymphatics. Grossly, the lymph nodes are enlarged and often soft. The adjourning mesentery may be edematous, with or without exudates. Microscopically, the lymph nodes show nonspecific hyperplasia and, in suppurative infection, necrosis with numerous pus cells.

Mesenteric adenitis (rare plural: adenitides), less commonly called mesenteric lymphadenitis (rare plural: lymphadenitides), is a self-limiting inflammatory process that affects the mesenteric lymph nodes in the right lower quadrant and is clinically often thought initially to be acute appendicitis, a common diagnostic mimic. […] The pathogenic micro-organisms are thought to gain access via intestinal lymphatics and then multiply in mesenteric lymph nodes. On gross pathology, lymph nodes are enlarged and soft. On microscopy, there is non-specific hyperplasia and when suppurative, there is necrosis and pus. […] Yersinia enterocolitica is considered the most common pathogen in temperate Europe, North America and Australia. It is more common in boys. […] Occasionally, enlarged mesenteric lymph nodes may result in vascular compromise leading to ischemic colitis.

Mesenteric lymphadenitis due to Yersinia enterocolitica infection is not common in Korea. […] The findings on laparotomy in such patients are usually enlarged mesenteric nodes with a normal or slightly inflamed appendix. […] Because histologic examination of the removed mesenteric lymph nodes reveals reactive hyperplasia in most cases, it is usually difficult to suspect Yersinia enterocolitica infection on morphology of the resected nodes. […] But suppurative granulomata of mesenteric lymph nodes, uncommonly encountered in Yersinia enterocolitica infection, strongly suggest yersinial infection.

Mesenteric adenitis, also known as mesenteric lymphadenitis, is a secondary syndrome caused by inflammation of the lymph nodes found in a membrane fold that joins the intestines to the abdominal wall, known as the mesentery. […] Primary mesenteric adenitis is idiopathic, meaning it develops for no known reason. When there are no abnormalities or heightened levels of inflammation in the abdomen causing the symptoms of mesenteric adenitis, it is considered primary. […] Secondary, on the other hand, can be caused by a variety of factors, including inflammatory bowel diseases (IBD, including Crohn’s disease and ulcerative colitis), chronic inflammatory diseases such as sarcoidosis and systemic lupus erythematosus (lupus), human immunodeficiency virus (HIV), tuberculosis (serious illness mainly affecting the lungs), infections such as mononucleosis, salmonella poisoning, and yersiniosis, viral infections that cause inflammation of the ileum, typhoid fever, and stomach flu. […] These infections cause the lymph nodes to swell when the body tries to filter them out of its system.

Mesenteric lymphadenitis reflects the mesenteric lymph node (MLN) response to an underlying infection of uncertain etiology, usually viral. […] Mesenteric adenitis is categorized as primary (nonspecific) and secondary. Primary mesenteric adenitis is mostly right sided, without an identifiable acute inflammatory cause. Secondary mesenteric adenitis is associated with a demonstrable intra-abdominal inflammatory etiology. […] MLN enlargement can be due to a primary etiology or else can be secondarily attributed to other causes such as infective etiology, malignancy, and inflammatory bowel diseases. […] In many children, no organic cause for recurrent abdominal pain can be established, and even when an abnormality is detected, it may be difficult to link the finding to the abdominal pain.

Mesenteric adenitis is a syndrome characterized by right lower quadrant pain secondary to an inflammatory condition of mesenteric lymph nodes. […] The etiologies of mesenteric adenitis include several causes of inflammatory response within mesenteric lymph nodes. These include viral infections, bacterial infections, inflammatory bowel disease, or lymphoma. […] Primary mesenteric adenitis is most commonly lymphadenopathy in the mesentery near the terminal ileum without a discoverable underlying cause for the inflammation. Mesenteric adenitis also presents secondary to bacterial or viral gastroenteritis. The pathophysiology for such infection to occur takes place as follows: The bacteria/virus is ingested orally and able to enter the body’s bloodstream via invasion through the intestinal epithelium. The organism then localizes to the nodal lymph tissue of the body surrounding intestinal mucosa; this commonly occurs in Peyer’s patches. From there, the organism can spread regionally through lymphatic pathways to mesenteric lymph nodes resulting in mesenteric adenitis.

SIRS is a generalized state of inflammation that can be triggered by a myriad of infectious and non-infectious causes, potentially leading to severe outcomes like sepsis or organ failure. […] Studies indicate that while mesenteric lymphadenitis is primarily a localized infection, systemic symptoms suggesting SIRS can occasionally emerge, especially if the lymphadenitis is part of a broader infectious or inflammatory process. […] Furthermore, the progression from mesenteric lymphadenitis to SIRS appears to be influenced by factors such as patient age, immune status, and presence of comorbid conditions. Young children and immunocompromised patients are particularly susceptible to such progression because of their relatively weaker immune responses. […] Management strategies for mesenteric lymphadenitis should therefore not only focus on alleviating local symptoms but also monitor signs of systemic inflammation to prevent escalation to SIRS. Early intervention with antibiotics or supportive care reduces the likelihood of progression and improves outcomes.
