Successful treatments with polymyxin B hemoperfusion and recombinant human thrombomodulin for fulminant Clostridium difficile-associated colitis with septic shock and disseminated intravascular coagulation: a case report
Clostridium difficile (CD)‐associated colitis (CDAC) is endemic and a common nosocomial enteric disease encountered by surgeons in modern hospitals due to prophylactic or therapeutic antibiotic therapies. Currently, the incidence of fulminant CDAC, which readily causes septic shock followed by multiple organ dysfunction syndromes, is increasing. Fulminant CDAC requires surgeons to perform a prompt surgery, such as subtotal colectomy, to remove the septic source. It is known that fulminant CDAC is caused by the shift from an inflammatory response at a local mucosal level to a general systemic inflammatory reaction in which CD toxin-induced mediators’ cascades disseminate. Recently, it has been proven that polymyxin B hemoperfusion (PMX-HP) improves septic shock and recombinant human thrombomodulin (rhTM) controls disseminated intravascular coagulation (DIC). In addition, clinically and basically, it has been shown that these treatments can control serous chemical mediators. Therefore, it is considered that these treatments are promising ones for patients with fulminant CDAC. In the current report, we present that these treatments without surgery contributed to the improvement of sepsis due to fulminant CDAC.
We encountered a case who developed fulminant CDAC with septic shock and DIC after laparoscopic gastrectomy for gastric cancer. At admission to the intensive care unit, his APACHE II score was 22, which indicated an estimated risk of hospital death of 42.4 %. Our therapies were not the subtotal colectomy to remove septic sources but the combination treatments with both PMX-HP and rhTM. These combination therapies resulted in excellent outcomes, namely the dramatic improvement of septic shock and DIC and the patient’s survival. We speculate that these combination therapies completely inhibit the CD toxin-induced mediators’ cascades and correspond to the removal of septic sources.
We recommend both PMX-HP and rhTM for patients who develop fulminant CDAC with septic shock and DIC to increase the survival benefit and replace the need for surgical treatment.

Clostridium difficile (CD)-associated colitis (CDAC), which is one of the common nosocomial enteric diseases encountered by surgeons, is typically due to the exposure of antibiotics and consequently endemic disease in modern hospitals [1, 2, 3]. Recently, the incidence of fulminant CDAC, which readily causes septic shock followed by multiple organ dysfunction syndromes (MODS), is increasing [4, 5, 6, 7]. Fulminant CDAC often requires surgeons to perform a prompt invasive surgical treatment, such as a subtotal colectomy, in order to remove the septic source and improve the patient’s fatal situation [7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19].
Recently, it has been proven that polymyxin B hemoperfusion (PMX-HP) improves septic shock [20, 21, 22, 23] and recombinant human thrombomodulin (rhTM) controls disseminated intravascular coagulation (DIC) [24, 25, 26, 27, 28, 29]. In addition, clinically and basically it has been shown that these treatments can control serous chemical mediators. On the other hand, it is known that fulminant CDAC with MODS is caused by the shift from an inflammatory response at a local mucosal level to a general systemic inflammatory reaction in which CD toxin-induced mediators’ cascades disseminate [30, 31, 32, 33, 34, 35, 36]. Therefore, it is considered that these treatments are promising ones for patients with fulminant CDAC.
In the current report, we present that these treatments without surgery contributed to the improvement of sepsis due to fulminant CDAC.

Currently, CDAC is endemic and a common nosocomial enteric disease encountered by surgeons in modern hospitals due to prophylactic or therapeutic antibiotic therapies [1, 2, 3]. Recently, both the incidence and the severity of CDAC have been increasing, and one possible explanation for these increases is the emergence of highly toxigenic and lethal strains of CD [4, 5, 6, 7]. The above shows the need for surgeons to consider more serious treatment against CDAC. In fulminant CDAC, which has a higher lethal rate, it is especially necessary for surgeons to promptly decide whether or not to perform an invasive surgical treatment, such as subtotal colectomy, which means the removal of the septic sources and probable improvement of the patients’ ill condition [7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19].
In our case that suddenly developed fulminant CDAC with septic shock requiring vasopressor agents and MODS composed of DIC and ARF, prompt surgical treatment in order to remove the septic sources was recommended. However, we alternatively treated the patient with both PMX-HP and rhTM therapies. The reason for having chosen these treatments is as follows: (1) there was neither colonic perforation nor toxic megacolon, which absolutely requires surgery; (2) PMX-HP is an effective extracorporeal blood purification treatment for improving septic shock ; and (3) rhTM can effectively inhibit systemic dissemination of intravascular coagulation [24, 25, 26, 27, 28, 29]. The combination therapies produced excellent outcomes in this case, namely the dramatic improvement of septic shock and DIC, the inhibition of MODS progression, and the patient’s survival. We speculate that the two below-mentioned factors corresponded to the removal of the septic source, namely as result of the surgical treatment. First, oral VCM medication could suppress CD’s proliferation and the further production of CD toxins. Second, both PMX-HP and rhTM could completely inhibit the CD toxin-induced mediators’ cascades. This notion is based on the following evidence. First, fulminant CDAC with MODS is caused by the shift from an inflammatory response at a local mucosal level to a general systemic inflammatory reaction in which CD toxin-induced mediators’ cascades disseminate [30, 31, 32, 33, 34, 35, 36]. Second, although PMX-HP removes circulating endotoxin by adsorption and theoretically prevents the progression of the biological cascade of sepsis, several studies and published reports have demonstrated that PMX-HP can reduce the plasma levels of cytokines and sepsis-related factors, namely TNF-α, IL-6, IL-10, N-arachidonoylethanolamine (AEA), 2-arachidonoyl glycerol (2-AG), and high-mobility group box-1 (HMGB-1) [21, 23, 38, 39]. Indeed, there were case reports published which showed that PMX-HP decreases the serum levels of endogenous cannabinoids (anandamide and 2-AG) and inflammatory cytokine (IL-6) in parallel with the clinical improvement of fulminant CDAC [40, 41]. Third, many studies and fundamental researches have shown that rhTM also has an anti-inflammatory ability through both the activated protein C and the lectin-like domain-dependent pathway [42, 43, 44, 45, 46]. In particular, the thrombin-rhTM complex demonstrates an anti-inflammatory ability through neutralizing HMGB-1 [47, 48], which is known to be a mediator of lethality and is released from necrotic cells or macrophages/activated dendritic cells with potent pro-inflammatory function, which in turn causes shock or MODS when being disseminated in the systemic circulation [49, 50, 51]. Finally, septic shock and MODS in our case were not induced by endotoxemia or bacteremia, and a dramatic improvement was observed immediately after the initiation of the combination therapies.
Both PMX-HP and rhTM therapies for patients who develop fulminant CDAC with septic shock and DIC can provide survival benefits and replace the need for invasive surgical treatments to remove the septic sources.
