Wrzody i karbunkuły
Patofizjologia i mechanizm

Wrzody (czyraki, furunkuły) i karbunkuły to bakteryjne infekcje skóry, głównie wywołane przez Staphylococcus aureus, w tym coraz częściej metycylinooporne szczepy MRSA. Wrzód to głęboka ropna martwica mieszka włosowego obejmująca skórę właściwą i tkankę podskórną, rozwijająca się po przerwaniu bariery naskórkowej i wniknięciu bakterii. Karbunkuł to złożona infekcja powstała z połączenia kilku wrzodów, cechująca się większą średnicą (2-10 cm), intensywniejszym bólem, licznymi punktami drenażu oraz objawami ogólnoustrojowymi, jak gorączka. Czynniki ryzyka obejmują m.in. osłabienie odporności (HIV/AIDS, cukrzyca), przewlekłe choroby skóry, nosicielstwo S. aureus, otyłość, urazy skóry oraz nieodpowiednią higienę. Infekcje te najczęściej lokalizują się w miejscach narażonych na tarcie i potliwość, takich jak tył szyi, twarz, pachy, pachwiny, pośladki i uda.

Patogeneza wrzodów i karbunkułów

Wrzody (czyraki, furunkuły) i karbunkuły to infekcje bakteryjne skóry, które różnią się głębokością i stopniem nasilenia procesu zapalnego. Zakażenia te dotyczą mieszków włosowych oraz otaczających tkanek, prowadząc do powstawania bolesnych, wypełnionych ropą zmian skórnych.12

Mechanizm powstawania wrzodów

Wrzód (czyrak) to zlokalizowana głęboka ropna martwicza postać zapalenia mieszka włosowego, obejmująca skórę właściwą i tkankę podskórną. Najczęstszym czynnikiem etiologicznym jest bakteria Staphylococcus aureus.12 Proces rozwoju wrzodu rozpoczyna się, gdy bakterie znajdujące się na powierzchni skóry przedostają się do mieszka włosowego poprzez drobne uszkodzenia naskórka, takie jak zadrapania, otarcia czy niewielkie rany.1

Po wniknięciu bakterii do mieszka włosowego, układ odpornościowy organizmu natychmiast reaguje, wysyłając białe krwinki (leukocyty) w celu zwalczenia infekcji. W wyniku tej odpowiedzi immunologicznej tworzą się bolesne, zaczerwienione guzki wokół mieszka włosowego.12 Z upływem czasu stan zapalny pogłębia się, powodując obumieranie tkanki wewnątrz wrzodu i tworzenie się jamy wypełnionej ropą (ropnia). Ropa składa się z martwych białych krwinek, obumarłych komórek skóry i bakterii.12

Wrzód stopniowo powiększa się, staje się miękki (chełbotliwy) i ostatecznie otwiera się samoistnie po kilku dniach do 1-2 tygodniach, uwalniając rdzeń martwiczej tkanki i ropę.12 Ból zmniejsza się w miarę zmniejszania ciśnienia, a zaczerwienienie i obrzęk ustępują w ciągu dni lub tygodni.1

Tworzenie się karbunkułów

Karbunkuł powstaje, gdy infekcja rozszerza się głębiej pod skórą, powodując połączenie kilku sąsiadujących wrzodów w większy, połączony obszar infekcji.12 Jest to skupisko czyrków (furunkułów), które łączą się podskórnie, tworząc większy i głębszy ropień z wieloma punktami drenażu (wieloma ujściami).12

Karbunkuły powodują głębszą i bardziej nasiloną infekcję niż pojedyncze wrzody. Charakteryzują się one większą średnicą (zazwyczaj 2-10 cm), bardziej intensywnym bólem, większą tendencją do pozostawiania blizn oraz mogą wywoływać objawy ogólnoustrojowe, takie jak gorączka i złe samopoczucie.12 Karbunkuły zazwyczaj wymagają bardziej intensywnego leczenia niż pojedyncze wrzody.1

Rola Staphylococcus aureus w patogenezie

Głównym czynnikiem etiologicznym wrzodów i karbunkułów jest bakteria Staphylococcus aureus, która naturalnie bytuje na skórze i w błonach śluzowych nosa.12 Bakteria ta posiada zdolność wytwarzania koagulazy, enzymu, który może powodować krzepnięcie krwi, co odgrywa istotną rolę w procesie infekcji.1

S. aureus wytwarza również enzymy i egzotoksyny, które przyczyniają się do nasilenia infekcji i uszkodzenia tkanek.1 Bakteria zwykle zasiedla skórę nie powodując objawów, koncentrując się głównie w miejscach, takich jak pachy, pachwiny, pośladki i szyja.1 Do infekcji dochodzi, gdy bakterie przedostaną się przez uszkodzoną barierę skórną do mieszka włosowego.1

Coraz częstszym czynnikiem przyczynowym wrzodów i karbunkułów staje się metycylinooporna postać Staphylococcus aureus (MRSA), która wykazuje oporność na niektóre antybiotyki, co może utrudniać leczenie.12

Czynniki predysponujące do rozwoju wrzodów i karbunkułów

Istnieje kilka czynników, które mogą zwiększać ryzyko rozwoju wrzodów i karbunkułów:12

  • Osłabienie układu odpornościowego – choroby takie jak HIV/AIDS, cukrzyca, niedożywienie, alkoholizm lub stosowanie leków immunosupresyjnych12
  • Przewlekłe choroby skóry – np. atopowe zapalenie skóry (AZS), łuszczyca, które naruszają integralność bariery skórnej12
  • Nosicielstwo S. aureus – zwłaszcza w jamie nosowej lub okolicach krocza12
  • Otyłość – zwiększa ryzyko rozwoju wrzodów i karbunkułów12
  • Gorący i wilgotny klimat – sprzyja namnażaniu się bakterii na skórze1
  • Nieodpowiednia higiena osobista1
  • Okluzja lub nieprawidłowa anatomia mieszków (np. zaskórniki w trądziku)1
  • Urazy skóry – drobne skaleczenia, zadrapania, ukąszenia owadów1

Szczególną uwagę należy zwrócić na pacjentów z cukrzycą, u których ryzyko rozwoju wrzodów i karbunkułów jest większe, a infekcje mają tendencję do cięższego przebiegu.1 Nie ma jednak jednoznacznych dowodów na bezpośredni związek między cukrzycą a nawracającymi czyraczycami (furunkulozą).1

Typowa lokalizacja wrzodów i karbunkułów

Wrzody i karbunkuły mogą rozwijać się w różnych częściach ciała, ale najczęściej występują w miejscach, gdzie skóra jest narażona na tarcie, okluzję i zwiększoną potliwość:12

  • Tył szyi12
  • Twarz1
  • Pachy1
  • Klatka piersiowa1
  • Pośladki12
  • Pachwiny1
  • Uda1
  • Talia1

Karbunkuły najczęściej występują na karku, plecach, ramionach lub udach.12

Procesy zapalne i immunologiczne w rozwoju wrzodów i karbunkułów

Rozwój wrzodów i karbunkułów jest ściśle związany z odpowiedzią immunologiczną organizmu na infekcję bakteryjną.1 Po wniknięciu bakterii do mieszka włosowego, układ odpornościowy inicjuje kaskadę reakcji zapalnych mających na celu zwalczenie patogenu.1

Odpowiedź zapalna

Proces zapalny rozpoczyna się od rozpoznania bakterii przez komórki układu odpornościowego. W odpowiedzi na infekcję, organizm wysyła do miejsca zakażenia białe krwinki, głównie neutrofile, które mają za zadanie zniszczyć bakterie.12 Ta odpowiedź immunologiczna powoduje powstanie klasycznych objawów zapalenia: zaczerwienienia, obrzęku, bólu i zwiększonej temperatury lokalnej.1

Neutrofile gromadzą się w miejscu infekcji i fagocytują (pochłaniają) bakterie w celu ich eliminacji. W procesie tym dochodzi do wydzielania enzymów i mediatorów zapalnych, które nasilają reakcję zapalną i powodują uszkodzenie okolicznych tkanek.1 Z czasem w miejscu infekcji gromadzą się martwe białe krwinki, martwe komórki skóry i bakterie, tworząc ropę.12

Formowanie ropnia

W miarę pogłębiania się procesu zapalnego, dochodzi do martwicy tkanki wewnątrz wrzodu i powstania jamy wypełnionej ropą, czyli ropnia.1 Ropa zawiera mieszaninę martwych bakterii, martwych białych krwinek i martwych komórek skóry.12 Organizm dąży do odizolowania infekcji poprzez utworzenie torebki wokół ropnia, co objawia się jako bolesny, zaczerwieniony guzek z centralnie położonym, miękkim obszarem gromadzenia się ropy.1

Z upływem czasu ropień dojrzewa, formuje „główkę” i ostatecznie pęka, uwalniając zawartość, co jest naturalnym mechanizmem oczyszczania infekcji.12 W przypadku wrzodów proces ten może trwać od kilku dni do 1-2 tygodni.1

Przejście od zapalenia mieszka włosowego do wrzodu i karbunkuła

Zapalenie mieszka włosowego (folliculitis) może przejść w głębszą infekcję, jaką jest czyrak (wrzód, furunculus), gdy proces zapalny rozszerza się na głębsze warstwy skóry i tkankę podskórną.12 Takie głębsze zapalenie mieszków włosowych ma zazwyczaj charakter infekcyjny, a najczęstszym patogenem jest Staphylococcus aureus.1

Jeśli proces zapalny obejmie kilka sąsiadujących mieszków włosowych, które łączą się ze sobą podskórnie, tworzy się karbunkuł.12 Karbunkuł charakteryzuje się obecnością wielu punktów drenażu (ujść) na powierzchni skóry, przez które wydobywa się ropa.1 Infekcja w karbunkule jest głębsza i bardziej rozległa niż w pojedynczym wrzodzie, co prowadzi do większego uszkodzenia tkanek i większego ryzyka pozostawienia blizny.1

Rola osłabionej odporności w rozwoju infekcji

Stan układu odpornościowego pacjenta odgrywa kluczową rolę w podatności na rozwój wrzodów i karbunkułów oraz w przebiegu infekcji.1 Osoby z osłabionym układem odpornościowym, na przykład w wyniku cukrzycy, HIV/AIDS, niedożywienia, alkoholizmu lub stosowania leków immunosupresyjnych, są bardziej narażone na rozwój tych infekcji.12

U osób z osłabioną odpornością bakterie mogą łatwiej wnikać do mieszków włosowych i mnożyć się, zanim układ odpornościowy zdoła je zniszczyć.1 Ponadto, infekcje u tych pacjentów mają tendencję do cięższego przebiegu, dłuższego trwania i większego ryzyka powikłań.1

Niektóre osoby mogą wykazywać większą podatność na wrzody niż inne, nawet jeśli są ogólnie zdrowe. Może to być związane z nosicielstwem specyficznego szczepu gronkowca, określanego jako PVL Staphylococcus (wytwarzającego toksynę Panton-Valentine Leukocydin), który zwiększa ryzyko nawracających infekcji skóry.1

Kolonizacja bakteryjna i jej rola w rozwoju infekcji

Kolonizacja skóry i błon śluzowych przez bakterie Staphylococcus aureus jest istotnym czynnikiem w patogenezie wrzodów i karbunkułów.1 Zrozumienie tego procesu pomaga wyjaśnić, dlaczego niektóre osoby są bardziej podatne na nawracające infekcje.

Nosicielstwo S. aureus

S. aureus jest częścią normalnej flory bakteryjnej skóry i błon śluzowych u wielu osób. Bakteria ta najczęściej kolonizuje:12

  • Jamę nosową – najbardziej powszechne miejsce kolonizacji1
  • Skórę – szczególnie w fałdach skórnych, takich jak pachy, pachwiny1
  • Okolice krocza i odbyt1

U osób będących nosicielami S. aureus, bakterie te żyją na skórze lub w nosie nie powodując objawów, ale mogą stać się przyczyną infekcji, gdy przedostaną się do uszkodzonej skóry.1 Nosicielstwo zwiększa ryzyko rozwoju wrzodów i karbunkułów oraz ich nawrotów.1

Mechanizm przejścia z kolonizacji do infekcji

Przejście od bezobjawowej kolonizacji do aktywnej infekcji wymaga naruszenia bariery skórnej, co umożliwia bakteriom wniknięcie do mieszków włosowych.1 Do typowych czynników ułatwiających to przejście należą:12

  • Drobne urazy skóry – zadrapania, otarcia, skaleczenia1
  • Ukąszenia owadów1
  • Tarcie skóry – np. przez ubranie, co może powodować obrzęk mieszka włosowego i zamknięcie jego ujścia1
  • Pocieranie i drapanie skóry – zwłaszcza w przypadku współistniejących chorób skóry1

Po przedostaniu się bakterii do mieszka włosowego, rozpoczyna się proces zapalny, który może prowadzić do powstania wrzodu, a następnie karbunkuła, jeśli infekcja rozprzestrzeni się na sąsiednie mieszki włosowe.1

Nawracające infekcje i rola nosicielstwa

Osoby z nawracającymi wrzodami (przewlekła czyraczność, furunkuloza) często są nosicielami S. aureus, co predysponuje ich do ponownych infekcji.1 U takich pacjentów bakterie mogą pozostawać w jamie nosowej lub okolicach krocza, stanowiąc rezerwuar dla przyszłych infekcji.1

Badania wykazują, że około 10% pacjentów z wrzodem lub ropniem rozwija nawrotową infekcję w ciągu 12 miesięcy.1 Czynniki związane z nawracającymi infekcjami to:1

  • Młodszy wiek (poniżej 30 lat)1
  • Nosicielstwo bakterii S. aureus12
  • Cukrzyca12
  • Otyłość12
  • Palenie tytoniu1
  • Stosowanie antybiotyków w ciągu sześciu miesięcy przed początkową infekcją12

W przypadku przewlekłej czyraczności istotne jest poszukiwanie i leczenie źródła nosicielstwa, a także rozważenie możliwych źródeł zewnętrznych, takich jak członkowie rodziny lub bliscy kontakty, którzy również mogą być nosicielami.12

Metycylinooporne szczepy S. aureus (MRSA)

Coraz większym problemem w patogenezie wrzodów i karbunkułów staje się zakażenie metycylinoopornymi szczepami Staphylococcus aureus (MRSA).1 MRSA to szczep bakterii, który wykazuje oporność na wiele powszechnie stosowanych antybiotyków, co utrudnia leczenie infekcji.1

Infekcje wywołane przez MRSA mogą być szczególnie problematyczne, ponieważ wymuszają zastosowanie silniejszych, często droższych antybiotyków. W przypadku podejrzenia infekcji MRSA, zaleca się wykonanie posiewu i antybiogramu w celu określenia wrażliwości bakterii na antybiotyki.12

Wrzody i karbunkuły wywołane przez MRSA mogą wymagać specjalistycznego leczenia, szczególnie jeśli nie są odpowiednio drenowane lub jeśli infekcja rozprzestrzeniła się poza pierwotne ognisko.1

Powikłania wrzodów i karbunkułów

Chociaż większość wrzodów i karbunkułów goi się bez poważnych konsekwencji, w niektórych przypadkach mogą wystąpić powikłania, szczególnie u osób z osłabionym układem odpornościowym.12

Lokalne powikłania

Do najczęstszych lokalnych powikłań wrzodów i karbunkułów należą:12

  • Zapalenie tkanki łącznej (cellulitis) – infekcja rozszerza się na głębsze warstwy skóry i tkankę podskórną12
  • Bliznowacenie – szczególnie w przypadku większych wrzodów i karbunkułów12
  • Nawracające infekcje – wrzody mogą nawracać w tym samym obszarze lub nigdy całkowicie nie ustąpić1
  • Przewlekła czyraczność (furunkuloza) – nawracające wrzody w różnych lokalizacjach1

Ogólnoustrojowe powikłania

W rzadkich przypadkach bakterie z wrzodu lub karbunkuła mogą przedostać się do krwiobiegu, powodując poważne infekcje ogólnoustrojowe:12

  • Bakteriemia – obecność bakterii we krwi1
  • Posocznica (sepsa) – ciężka, ogólnoustrojowa reakcja na infekcję we krwi12
  • Zapalenie wsierdzia – infekcja wewnętrznej wyściółki serca12
  • Zapalenie kości i szpiku (osteomyelitis) – infekcja kości12
  • Zakrzepowe zapalenie zatoki jamistej – rzadkie, ale poważne powikłanie wrzodów i karbunkułów na twarzy1
  • Ropnie mózgu – bardzo rzadkie powikłanie12

Ryzyko tych poważnych powikłań jest większe u pacjentów z osłabionym układem odpornościowym oraz w przypadku nieskutecznego lub opóźnionego leczenia.1

Nawracające infekcje

U niektórych pacjentów wrzody mają tendencję do nawracania, co określa się jako przewlekłą czyraczność (furunkulozę).1 Czynniki ryzyka nawracających infekcji obejmują:12

  • Nosicielstwo S. aureus w jamie nosowej lub na skórze1
  • Cukrzyca12
  • Otyłość12
  • Ekspozycja zawodowa lub przemysłowa na czynniki drażniące1
  • Współistniejące choroby skóry, takie jak atopowe zapalenie skóry1

W leczeniu nawracających infekcji istotne jest identyfikowanie i eliminowanie potencjalnego źródła nosicielstwa oraz stosowanie odpowiednich środków zapobiegawczych.12

Powikłania związane z MRSA

Infekcje wywołane przez metycylinooporne szczepy Staphylococcus aureus (MRSA) mogą być szczególnie trudne do leczenia i mogą prowadzić do poważniejszych powikłań.1 MRSA jest związany z wyższym ryzykiem nawracających infekcji oraz z cięższym przebiegiem choroby.1

W przypadku podejrzenia infekcji MRSA, szczególnie ważne jest odpowiednie drenowanie zmiany oraz wdrożenie odpowiedniego leczenia antybiotykami, dobranego na podstawie antybiogramu.12

Znaczenie odpowiedniego drenażu w leczeniu wrzodów i karbunkułów

Podstawowym elementem skutecznego leczenia wrzodów i karbunkułów jest zapewnienie odpowiedniego drenażu ropnia.12 Jest to kluczowy krok, który umożliwia usunięcie martwiczej tkanki i ropy, przyspieszając proces gojenia.

Mechanizm drenażu i jego znaczenie

Drenaż wrzodu lub karbunkuła pozwala na usunięcie ropy, która zawiera martwe białe krwinki, bakterie i martwą tkankę.1 Usunięcie tej zawartości jest niezbędne do prawidłowego procesu gojenia, ponieważ:12

  • Zmniejsza presję wewnątrz ropnia, co przynosi ulgę w bólu1
  • Usuwa środowisko sprzyjające namnażaniu się bakterii1
  • Przyspiesza proces gojenia1
  • Ogranicza formowanie się blizn1
  • Zmniejsza ryzyko rozprzestrzenienia się infekcji1

Wrzody i karbunkuły zwykle muszą zostać zdrenowane, aby mogły się zagoić.1 W przypadku karbunkułów, które są głębszymi i bardziej złożonymi infekcjami, szczególnie ważne jest ich nacięcie i drenaż, aby umożliwić odpływ ropy.1

Samoistny drenaż

Mniejsze wrzody mogą samoistnie drenować się po dojrzeniu i utworzeniu „główki”.1 Proces ten zazwyczaj następuje w ciągu 5-7 dni u zdrowych osób.12 Po samoistnym pęknięciu wrzodu i odpływie ropy, ból zmniejsza się, a proces gojenia przyspiesza.1

Karbunkuły również mogą drenować się samoistnie, ale proces ten trwa dłużej i może być niepełny ze względu na ich głębsze położenie i złożoną strukturę z wieloma połączonymi ropniami.1 Samoistny drenaż karbunkuła zazwyczaj następuje w ciągu dwóch tygodni.1

Drenaż chirurgiczny wykonywany przez lekarza

W przypadku większych wrzodów, karbunkułów lub gdy samoistny drenaż nie następuje, niezbędna jest interwencja medyczna.12 Procedura drenażu chirurgicznego polega na:12

  • Znieczuleniu miejsca zmiany za pomocą środka miejscowo znieczulającego1
  • Wykonaniu małego nacięcia na wrzodzie lub karbunkule1
  • Drenażu ropy i usunięciu martwiczej tkanki1
  • W przypadku głębokich infekcji, które nie mogą być całkowicie zdrenowane, można zastosować sterylną gazę do wchłonięcia i usunięcia dodatkowej ropy1

Karbunkuły zazwyczaj wymagają drenażu chirurgicznego ze względu na ich głębsze położenie i większy rozmiar.1 Procedura ta jest zazwyczaj wykonywana ambulatoryjnie, w znieczuleniu miejscowym.1

Zastosowanie ciepła w ułatwianiu drenażu

Ciepłe kompresy mogą pomóc w ułatwieniu drenażu wrzodów i karbunkułów poprzez:12

  • Zwiększenie przepływu krwi do obszaru infekcji1
  • Przyspieszenie dojrzewania wrzodu i formowania „główki”1
  • Zmiękczenie tkanek, co ułatwia naturalny drenaż1

Zaleca się stosowanie ciepłych, wilgotnych kompresów na obszar infekcji przez 20-30 minut, 3-4 razy dziennie.12 W przypadku większych zmian można również stosować poduszkę grzewczą na obszar infekcji przez około 20 minut.1

Po drenażu wrzodu lub karbunkuła, nadal zaleca się stosowanie ciepłych kompresów, aby ułatwić dalszy odpływ ropy i przyspieszać gojenie.1

Znaczenie antybiotyków po drenażu

W przypadku odpowiedniego drenażu, antybiotyki często nie są konieczne do leczenia niepowikłanych wrzodów i karbunkułów.1 Jednak w niektórych sytuacjach, antybiotykoterapia jest zalecana:12

  • Gdy pacjent ma obniżoną odporność1
  • Gdy występuje gorączka lub inne objawy ogólnoustrojowe1
  • Gdy istnieje ryzyko zapalenia wsierdzia1
  • Gdy zmiany są wieloogniskowe lub rozszerzają się1
  • Gdy występuje zapalenie tkanki łącznej (cellulitis) wokół zmiany1
  • W przypadku infekcji MRSA, które nie zostały całkowicie zdrenowane1

W takich przypadkach, wybór antybiotyku powinien być oparty na posiewie i antybiogramie, aby zapewnić skuteczność przeciwko konkretnym bakteriom wywołującym infekcję.12

    Boils (furuncles) are a localized deep suppurative necrotizing form of folliculitis which involve the dermis and the subcutaneous tissue. Staphylococcus aureus is the most common causative agent. Following an abrasion or cut, the pathogen uses the wound site to invade and colonize the hair follicle. This leads to the formation of tender, erythematous, perifollicular nodule. The boil later becomes painful and fluctuant leading to discharge of pus and formation of necrotic plugs, which may leave a scar.

    A boil is a painful, pus-filled bump that forms under your skin when bacteria infect and inflame one or more of your hair follicles. A carbuncle is a cluster of boils that form a connected area of infection under the skin. […] Most boils are caused by Staphylococcus aureus, a type of bacterium commonly found on the skin and inside the nose. A bump forms as pus collects under the skin. Boils sometimes develop at sites where the skin has been broken by a small injury or an insect bite, which gives the bacteria easy entry. […] A carbuncle is a cluster of boils that form a connected area of infection. Compared with single boils, carbuncles cause a deeper and more severe infection and are more likely to leave a scar.

    A boil (furuncle) is a pus-filled bump in the skin that is caused by a bacterial infection. […] Boils develop when a hair follicle and the surrounding tissue become infected. […] The infection causes the skin tissue inside the boil to die, creating a pus-filled hollow space (an abscess). […] If several boils merge into a larger bump, its called a carbuncle. […] Boils are caused by bacteria, most commonly by Staphylococcus aureus bacteria (a staph infection). […] For this reason, boils are more common in people with medical conditions such as diabetes, chronic infections or cancer. […] If several boils develop in neighboring hair follicles and merge into a larger connected area of infection under the skin, its called a carbuncle. […] Doctors can feel the boil with their hands to see whether that is the case. […] Antibiotics are only needed if complications are likely or have already occurred for instance, if several boils have merged and developed into a carbuncle. […] It is particularly important that carbuncles are cut open so that the pus can escape.

    A furuncle (boil) is a deep-seated infection (abscess) caused by S. aureus and involving the entire hair follicle and adjacent subcutaneous tissue. […] By way of contrast, a carbuncle consists of several furuncles developing in adjoining hair follicles and coalescing to form a conglomerate, deeply situated mass with multiple drainage points. […] The abscess is either rounded or conical. It gradually enlarges, becomes fluctuant, and then softens and opens spontaneously after a few days to 1-2 weeks to discharge a core of necrotic tissue and pus. […] Potential complications of staphylococcal infection include septicemia. […] Treatment consists primarily of incision and drainage for all loculated suppurations. Systemic antibiotics are usually given although they offer little beyond adequate incision and drainage.

    Eradication of nasal carriage of staphylococci can be achieved with a cream of chlorhexidine with neomycin (Naseptin) applied to the nostrils four times a day for 10 days. […] Oral flucloxacillin or erythromycin are usually effective against S. aureus infections. […] In chronic furunculosis, the choice of antibiotic ideally should be guided by sensitivities. […] Boils and carbuncles can leave scars. […] Surrounding cellulitis or bacteraemia may develop if furunculosis or carbuncles extend. […] Cavernous sinus thrombosis can complicate boils or carbuncles on the face but this is rare. […] Metastatic infection is rare but can include osteomyelitis, acute endocarditis or brain abscess. Septicaemia is a very rare complication of both furuncles and carbuncles. […] Over a course of two days to three weeks the boil becomes necrotic and develops into an abscess. It ruptures and discharges pus and often a core of necrotic material. Pain subsides as pressure is reduced; the redness and oedema diminish over days to weeks.

    Furuncles (boils) are skin abscesses caused by staphylococcal infection, which involve a hair follicle and surrounding tissue. Carbuncles are clusters of furuncles connected subcutaneously, causing deeper suppuration and scarring. […] Diagnosis is by appearance. Treatment is warm compresses and often oral antistaphylococcal antibiotics. […] Both furuncles and carbuncles may affect healthy young people but are more common among people who have obesity, are immunocompromised (including those with neutrophil defects), are older, and possibly those who have diabetes. […] Predisposing factors include bacterial colonization of skin or nares, hot and humid climates, and occlusion or abnormal follicular anatomy (eg, comedones in acne). […] Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause.

    After incision and drainage, oral antibiotics are typically initiated; this is of particular importance if the patient has any systemic symptoms or if there is any surrounding cellulitis. […] The differential diagnosis for carbuncle includes cystic acne, hidradenitis suppurativa, cellulitis, osteomyelitis, orf, anthrax, and arthropod bite. […] A carbuncle develops over several days to several weeks, reaching a diameter of 2 to 10 cm.

    Boils are painful, red, pus-filled lumps on your skin caused by an infection of hair follicles. […] One infected hair follicle is called a furuncle, and a group of infected follicles joined together is known as a carbuncle. […] Boils are usually caused by infection with the bacteria staphylococcus aureus. These bacteria usually live on your skin without causing harm, but can sometimes infect hair follicles, for example, if the skin is broken. The infection can spread to other parts of your body, or to other people. […] For larger boils and carbuncles, see your doctor. They may need to make a small cut in the boil to help the pus drain, and you may need antibiotics. Large boils and carbuncles can leave a scar on the skin. […] Sometimes there is a cluster of boils (carbuncle). If you have a carbuncle, you may have fever and feel generally unwell. Carbuncles are more likely to need antibiotics and see a doctor to have the pus drained.

    https://my.clevelandclinic.org/health/diseases/15153-boils-and-carbuncles
    A boil is a skin infection that is usually caused by the bacteria Staphylococcus aureus (staph). A carbuncle is a group of boils located in one area of the body. Boils are usually caused by the bacteria Staphylococcus aureus (staph infection). These painful skin abscesses result from bacteria infecting a hair follicle. Carbuncles develop when more than one hair follicle gets infected. The infection is deeper and more severe than one boil. Boils are usually caused by the bacteria Staphylococcus aureus (staph infection), but other bacteria and fungi can cause them too. Bacteria enter your skin through a cut or a hair follicle (the opening in your skin where hair grows out). Your body’s immune system responds by sending infection-fighting white blood cells to the area. The white blood cells build up, along with damaged skin, to form pus.
  • #1 Boil – Wikipedia
    https://en.wikipedia.org/wiki/Boil
    A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. […] Most human infections are caused by coagulase-positive S. aureus strains, notable for the bacteria’s ability to produce coagulase, an enzyme that can clot blood. […] S. aureus strains first infect the skin and its structures (for example, sebaceous glands, hair follicles) or invade damaged skin (cuts, abrasions). […] Sometimes the infections are relatively limited (such as a stye, boil, furuncle, or carbuncle), but other times they may spread to other skin areas (causing cellulitis, folliculitis, or impetigo).

    S. aureus strains also produce enzymes and exotoxins that likely cause or increase the severity of certain diseases. Such diseases include food poisoning, septic shock, toxic shock syndrome, and scalded skin syndrome. […] Poor immune system function such as from HIV/AIDS, diabetes, malnutrition, or alcoholism. […] An associated skin disease favors recurrence. This may be attributed to the persistent colonization of abnormal skin with S. aureus strains, such as is the case in persons with atopic dermatitis.

    A boil (furuncle) is an infection of a hair follicle. A carbuncle occurs when a group of hair follicles next to each other become infected. It is like a multiple boil. Chronic furunculosis is a condition where you have crops of boils that occur over a longer period of time. […] Boils are caused by germs (bacteria) multiplying below the skin surface. […] Your immune system is important in helping you to fight off infection. […] That means you have a higher risk of developing a boil or carbuncle if germs get under your skin and your immune system does not kill them quickly enough to stop them multiplying. […] One cause of recurring boils if you are otherwise healthy is that you, or someone in your family or household, may be a carrier of a special type of staphylococcal germ (bacteria), which is called PVL staphylococcus. This means that a certain number of these bacteria live harmlessly on your skin, or in your nose. If you are a carrier, you tend to be more prone to skin infections and boils.

  • #1 What Is a Carbuncle?
    https://www.drhoffmandermatology.com/blog/446193-what-is-a-carbuncle
    A boil is an infection of the hair follicle that develops under the skin. When multiple boils develop this is known as a carbuncle. In a carbuncle, this cluster of boils is interconnected under the skin and can lead to pain, inflammation, and redness. This infection most often develops on areas of the body that contain hair such as the neck, back, or armpits, but can also develop on the thighs and groin. […] Most of the time, bacteria known as staphylococcus aureus are to blame for carbuncles. This bacteria is already present on the skin, but can easily get into a hair follicle through a cut or opening. Since a carbuncle is the result of a bacterial infection, the infection can be spread to others by sharing items such as towels or through skin-to-skin contact. […] It is important that you do not pick at or squeeze the bump, as this can spread the infection even further or lead to scarring. Apply warm compresses to the area several times a day. Make sure to keep the area clean (wash with soap and water) and cover the area. Since heat can help to facilitate natural drainage, you may want to use a heating pad on the area for up 20 minutes at a time.

    A boil is a skin infection that is usually caused by the bacteria Staphylococcus aureus (staph). A carbuncle is a group of boils located in one area of the body. Boils are usually caused by the bacteria Staphylococcus aureus (staph infection). These painful skin abscesses result from bacteria infecting a hair follicle. Carbuncles develop when more than one hair follicle gets infected. The infection is deeper and more severe than one boil. Boils are usually caused by the bacteria Staphylococcus aureus (staph infection), but other bacteria and fungi can cause them too. Bacteria enter your skin through a cut or a hair follicle (the opening in your skin where hair grows out). Your body’s immune system responds by sending infection-fighting white blood cells to the area. The white blood cells build up, along with damaged skin, to form pus.

[…] A boil is a localized infection in the skin that begins as a reddened, tender area. Over time, the area becomes firm, hard, and increasingly tender. Eventually, the center of the boil softens and becomes filled with infection-fighting white blood cells from the bloodstream to eradicate the infection. This collection of white blood cells, bacteria, and proteins is known as pus. Finally, the pus „forms a head,” which can be surgically opened or may spontaneously drain out through the surface of the skin. A pus enclosed within tissue is referred to as an abscess.

    https://www.verywellhealth.com/carbuncle-8770485
    The most common cause of a carbuncle is a bacterial infection caused by the Staphylococcus aureus bacteria, also known as a staph infection. Methicillin-resistant S. aureus (MRSA), which is resistant to some common antibiotics, is also becoming a common cause of carbuncles. […] For healing to occur, a carbuncle must first be drained. In some cases, the growth will rupture and drain on its own within two weeks of its development. However, those that are deeper may not do so independently and require the help of a healthcare provider. […] If medical removal is necessary, a healthcare provider must perform a surgical procedure known as an incision and drainage. To drain a carbuncle, a healthcare provider will numb the site with local anesthesia and make an incision in the carbuncle to help remove the pus.

    A boil is a tender red lump on your skin caused by an infection of a hair root or sweat pore. […] Boils are usually caused by a bacteria called Staphylococcus aureus, which often lives harmlessly on human skin. However, any break in your skin barrier leaves it vulnerable to infection and can lead to the development of a boil. Large boils can form an abscess, which is the build-up of pus in a pocket under your skin. A cluster of boils that have multiple white pus heads is called a carbuncle. […] Larger boils and abscesses might need to be drained to get the pus out. This means that your healthcare provider will make a small cut in your skin so the pus can drain out. This is also called lancing the boil. […] Antibiotics arent usually needed after drainage of a straightforward abscess. But you might need them if the abscess is infected, or you have/are at risk of cellulitis (an infection that affects the deeper layers of your skin).
