Clinical efficacy of ulinastatin in the treatment of unliquefied pyogenic liver abscess complicated by septic shock: A randomized controlled trial.

INTRODUCTION: This study determined the therapeutic effect of ulinastatin (UTI) on unliquefied pyogenic liver abscesses complicated by septic shock (UPLA-SS). METHODS: This was a randomized controlled trial involving patients with UPLA-SS who underwent treatment at our hospital between March 2018 and March 2022. The patients were randomly divided into control (n = 51) and study groups (n = 48). Both groups received routine treatment, but the study group received UTI (200,000 units q8h for >3 days). Differences in liver function, inflammatory indices, and effectiveness between the two groups were recorded. RESULTS: Following treatment, the white blood cell count, and lactate, C-reactive protein, procalcitonin, tumor necrosis factor-α, and interleukin-6 levels were significantly decreased in all patients compared to the admission values (p < .05). The study group had a faster decline with respect to the above indices compared to the control group (p < .05). The study group length of intensive care unit stay, fever duration, and vasoactive drug maintenance time were all significantly shorter than the control group (p < .05). The total bilirubin, alanine aminotransferase, and aspartate aminotransferase levels were significantly lower in the study and control groups after treatment compared to before treatment (p < .05); however, the study group had a faster recovery of liver function than the control group (p < .05). The overall mortality rate was 14.14% (14/99); 10.41% of the study group patients died and 17.65% of the control group patients died, but there was no statistically significant difference between the two groups (p > .05). CONCLUSION: UTI combined with conventional treatment significantly controlled the infection symptoms, improved organ function, and shortened the treatment time in patients with UPLA-SS.

Streptococcus pyogenes bacteremia and toxic shock syndrome related to Strongyloides stercoralis hyperinfection: a case report.

BACKGROUND: We describe a patient with Strongyloides stercoralis hyperinfection associated with Streptococcus pyogenes and with streptococcal toxic shock syndrome. To the best of our knowledge this association has not been previously described. CASE PRESENTATION: A 78 year-old Israeli man, who was born in Iraq but lived in Israel for 66 years, presented with multi-organ failure including acute kidney and hepatic injury, coagulopathy, and lactic acidosis. He had a medical history including aortic valve replacement, diabetes mellitus, spinal stenosis, and low back pain treated with repeated local steroid injections. Blood cultures were positive for Streptococcus pyogenes and antibiotic treatment was switched to penicillin G, clindamycin, and intravenous immunoglobulins. Repeated physical examinations failed to identify the source of the bacteremia. On day 12 of hospitalization the serology results for Strongyloides stercoralis sent on admission, because of chronic eosinophilia, came back positive. A microscopic stool examination and stool polymerase chain reaction were positive for Strongyloides stercoralis. Ivermectin therapy was commenced and continued for a total of 4 weeks. He was discharged for rehabilitation after 25 days. He had no exposure to endemic countries or to immigrants. During many years he had multiple gastrointestinal symptoms, respiratory symptoms, cutaneous symptoms, chronic eosinophilia, and high immunoglobulin E levels. He underwent several operative procedures and numerous hospitalizations and medical encounters with different experts but a parasitic infection was not considered. His asymptomatic daughter was also found to be serologically positive. CONCLUSIONS: Strongyloides stercoralis hyperinfection associated with Streptococcus pyogenes bacteremia and toxic shock is described for the first time. The case also highlights the importance of history taking and reviewing past laboratory results, the utility of serological tests for Strongyloides stercoralis, and the importance of screening asymptomatic family members of an infected patient. Strongyloides stercoralis hyperinfection must be considered in the differential diagnosis of any patient with Streptococcus pyogenes bacteremia or toxic shock of no clear source as well as in symptomatic patients with chronic or intermittent eosinophilia, even without any epidemiological risk factors.

Severe Plasmodium knowlesi with dengue coinfection.

We report a case of severe Plasmodium knowlesi and dengue coinfection in a previously healthy 59-year-old Malay man who presented with worsening shortness of breath, high-grade fever with chills and rigors, dry cough, myalgia, arthralgia, chest discomfort and poor appetite of 1 week duration. There was a history mosquito fogging around his neighbourhood in his hometown. Further history revealed that he went to a forest in Jeli (northern part of Kelantan) 3 weeks prior to the event. Initially he was treated as severe dengue with plasma leakage complicated with type 1 respiratory failure as evidenced by positive serum NS1-antigen and thrombocytopenia. Blood for malarial parasite (BFMP) was sent for test as there was suspicion of malaria due to persistent thrombocytopenia despite recovering from dengue infection and the presence of a risk factor. The test revealed high count of malaria parasite. Confirmatory PCR identified the parasite to be Plasmodium knowlesi Intravenous artesunate was administered to the patient immediately after acquiring the BFMP result. Severe malaria was complicated with acute kidney injury and septicaemic shock. Fortunately the patient made full recovery and was discharged from the ward after 2 weeks of hospitalisation.

Coinfection of Leishmania guyanensis and Human Immunodeficiency Virus-Acquired Immune Deficiency Syndrome: Report of a Case of Disseminated Cutaneous Leishmaniasis in Ecuador.

AbstractReported herein is the first case of Leishmania-human immunodeficiency virus (HIV) coinfection in Ecuador. In Ecuador, HIV infections overlap endemic areas of leishmaniasis. Immunosuppression is a well-established risk factor for developing severe disease. This is a severe case of a 32-year-old man presenting with disseminated pleomorphic ulcers, papules, and cutaneous plaque-like lesions over his whole body. Numerous amastigotes were observed in both skin scrapings and biopsies. The sequence of the cytochrome b gene confirmed the presence of Leishmania guyanensis. The patient was treated but failed to respond to meglumine antimoniate and amphotericin B. Six months later, the patient died due to bacterial septic shock.

Strongyloidiasis: an unusual cause of septic shock with pneumonia and enteropathy in western countries.

We report a case of invasive strongyloidiasis in a patient from the French Antilles who had been living in France for many years, with no history of immunosuppression, and who was hospitalised in the intensive care unit for septic shock with multimicrobial hypoxaemia pneumonia and exudative enteropathy. Initiation of systemic corticosteroid therapy for septic shock seems to have precipitated onset of the parasitic infection, with recurrence of hypoxaemic pneumonia complicated by hypoxic cardiac arrest. The diagnosis was confirmed after roundworm larvae were found on bronchoalveolar lavage. Treatment with ivermectin was initiated, but the patient died in a context of postanoxic encephalopathy.

Disseminated toxoplasmosis presenting as septic shock five weeks after renal transplantation.

We discuss a case of acute disseminated toxoplasmosis in a renal transplant recipient presenting with septic shock. Our literature review of disseminated toxoplasmosis presenting as septic shock reveals a disease process that is rapid and almost uniformly fatal. This unusual presentation warrants a high index of suspicion in transplant recipients with immediate administration of appropriate empiric antimicrobials.

Fatal septicemic shock associated with Strongyloides stercoralis infection in a patient with angioimmunoblastic T-cell lymphoma: a case report and literature review.

INTRODUCTION: Strongyloides stercoralis infection can persist in the host for several decades, and patients with cancer and other clinical conditions who are exposed to immunosuppressive therapy are at risk of developing hyperinfection. CASE REPORT: This is a case of angioimmunoblastic T-cell lymphoma (AITL) in a patient with lymphadenopathy and bulky neck mass. Severe sepsis and episodes of diarrhea were observed upon the first cycle of cyclophosphamide, doxorubicin, oncovin (vincristine) and prednisone (CHOP) regime chemotherapy preceded by high dose of dexamethasone. There was Klebsiella pneumoniae bacteremia and moderate eosinophilia. Rhabditiform S. stercoralis larvae were observed in the stool, and this was confirmed by real-time PCR. Strongyloides-specific IgG and IgG4 were also positive. The patient was treated with oral albendazole (400mg/day) for 3 days and intravenous tazocin (4.5gm/6 hours) for 5 days; however he succumbed following multi-organ failure. CONCLUSION: This is likely a case of Strongyloides hyperinfection with secondary bacteremia.

Fatal case of ectopic enterobiasis: Enterobius vermicularis in the kidneys.

Enterobius vermicularis is one of the most common intestinal parasites found in humans. They commonly infest the terminal ileum and large intestine, and are usually considered an innocuous parasite that can be easily eradicated with proper treatment. However, extraintestinal migration of worms, although very rare, may lead to severe health disorders or even death. This article, reports the first fatal case of ectopic enterobiasis known to the authors, which developed in an adult patient with E. vermicularis infection, causing perforation of the large intestine and generalized bacterial peritonitis. Despite emergency laparotomy, the patient died from septic shock on the day after surgery. During pathological examination, worms were found not only in the large intestine, but also in the renal parenchyma; worm eggs were found deposited in the lungs as well.

[Malignant hydatid disease--clinical case]. / Hidatidoza maligna--caz clinic.

We report the case of a 79-year-old woman admitted for sepsis from a hepatic hydatid cyst with multiple disseminations diagnosed one month earlier who refused the surgical treatment. Her family history was irrelevant with regard to the circumstances leading to Taenia Echinococcus infestation, and given her poor health status and absence of previous medical documents no useful information was obtained from her medical history. The patient also presented chronic ischemic heart disease and anemia secondary to a bleeding duodenal ulcer, found at necropsy, which worsened the already unfavorable course by the acute hepatic and renal failure secondary to toxic and septic shock. Despite the complex treatment, death occurred 6 days later, following a second episode of upper digestive hemorrhage. Particular to this case is the absence in patient's history of the anaphylactic/allergic reactions suggestive of hepatic hydatid cyst dissemination.

Delayed onset of severe neonatal toxoplasmosis.

We report a case of severe neonatal infection on day 6 of life due to Toxoplasma gondii mimicking septic shock syndrome associated with multiple organ failure such as acute respiratory distress syndrome with persistent pulmonary hypertension, neurological distress, thrombocytopenia with disseminated intravascular coagulopathy and transaminitis. Clinicians facing an unexplained life-threatening condition in the first week of life should take into consideration the possibility of neonatal toxoplasmosis.

Septic shock due to visceral leishmaniasis, probably transmitted from blood transfusion.

A case of visceral leishmaniasis (VL) in a 77-year-old woman, with renal failure on haemodialysis, admitted in the intensive care unit (ICU) with vascular instability requiring vassopressor treatment, is presented. Initially, no co-infection could be detected. The patient initially responded well when liposomal amphotericin B was administered, after bone marrow demonstrated multiple intra-cellular Leishmania amastigotes and extra-cellular promastigotes. However, the patient died from uncontrolled septic shock from a secondary bacterial infection, the tenth day of admission. To our knowledge, vascular instability has not been reported in VL. Moreover, non-vector transmission was also suspected in this case. The patient had undergone cholecystectomy three months earlier, during which two blood units had been transfused; IgG anti-Leishmania antibodies at a high titer were detected in one of the two healthy blood donors, later.

Two cases of Plasmodium vivax Malaria with the clinical picture resembling toxic shock.

Fatal complications of Plasmodium falciparum malaria have been reported. However, complicated P. vivax malaria is rare. We observed two unusual cases of P. vivax malaria who presented with clinical pictures of toxic shock. Both showed disseminated intravascular coagulation with marked thrombocytopenia, oliguric renal failure, and pulmonary edema. Examination of initial blood smears showed a P. vivax parasitemia of 2,352/microL and 12,376/microL, respectively. The patients were treated with hydroxychloroquine and primaquine without an antibacterial agent. These cases emphasize the importance of considering the possibility of P. vivax malarial infection in patients with a clinical picture resembling toxic shock if they have a travel history to malaria-endemic areas.

[Septic shock due to congenital disseminated toxoplasmosis?]. / Toxoplasmose congénitale disséminée responsable d'un choc septique?

Congenital toxoplasmosis secondary to maternal primary infection acquired late during pregnancy is generally asymptomatic at birth. We report a case of a newborn infant whose mother had been infected between the 27th and the 33rd week of gestation. No treatment had been given during gestation. The infant had a disseminated form of toxoplasmosis with hepatosplenomegaly, pneumonitis, purpura, hepatitis. On the third day of life, he developed shock. The patient died early despite therapy. Septic shock is unusual in congenital toxoplasmosis, although it has been described in immunocompromised patients, notably in patients infected with the human immunodeficiency virus.

Septic shock due to babesiosis.

We present the case of a 69-year-old man with an unremarkable past medical history and an intact spleen who developed shock and renal failure due to babesiosis. Despite hemodynamic parameters showing severe distributive shock with hyperdynamic cardiac function, the patient recovered fully after treatment with quinine sulfate and clindamycin.

Ascaris-induced liver abscess.

The prevalence, symptomatology, and outcome of Ascaris-induced liver abscess was studied prospectively in Kashmir, India, which is an endemic area of ascariasis, from December 1987 to December 1997. Of 510 patients with liver abscess admitted during this period, 74 had biliary ascariasis as the cause (14.51%). Of these 74 patients, 11 had intact ascaridae (live or dead) within the abscess. Six patients had a single abscess, and five had multiple abscesses. Seven patients had associated worms in the bile ducts. Ultrasonography was the main diagnostic procedure used. Ten patients were diagnosed based on clinical and ultrasound findings, and one was diagnosed during laparotomy. Most of the patients were young (age range 3-40 years) with a mean age of 17.20 years. Seven were females, and four were males. Ten patients underwent surgery; nine recovered completely, and one died postoperatively due to septicemia. Another patient died as well: a young child who presented late, was in refractory septic shock following suppurative cholangitis and liver abscess, and could not be taken for surgery. The mortality thus was 9.9%. Liver abscess following invasion of intrahepatic biliary radicles by ascaridae through the ampulla is an unusual complication of an otherwise common disease in Kashmir Valley, affecting children and young adults. The outcome depends on early diagnosis and surgical drainage of the abscess with extraction of worms from the ducts.

Acute respiratory distress syndrome due to falciparum malaria in a pregnant woman.

We report the case of a pregnant woman (29th week), living in a Paris suburb, about 20 miles from an international airport. She presented with septic shock and severe acute respiratory distress syndrome (ARDS). A few parasitized erythrocytes were discovered in a hemorrhagic bronchoalveolar lavage (BAL), specimen and many were found on examination of the placenta after a caesarean section had been performed. The patient's condition dramatically improved once given quinine therapy. This is an uncommon case on account of: (1) the unusual clinical course with no organ failure but ARDS, (2) the unusual way the diagnosis was made, (3) the very unusual way the patient became contaminated (airport malaria), (4) the pregnant condition of the patient.

Intestinal obstruction caused by Ascaris lumbricoides.

PURPOSE: The aim of this study is to present patients, to discuss causes of morbidity and mortality, and to ascertain prognostic indexes and therapeutic options influencing outcome of patients with intestinal obstruction caused by Ascaris lumbricoides. MATERIALS AND METHODS: During the past 20 years, between 1975 and 1995, a total of 17 patients with intestinal obstruction attributable to A. lumbricoides underwent surgery. Five were adults, and 12 were children. The most frequent symptoms and physical findings were abdominal pain, distention, nausea, vomiting, and constipation. Enterotomy was performed in ten patients and resection in two patients. Manual exposition and advancement of the parasitic bundle toward the colon was attempted in five patients. Morbidity and mortality rates were 29 and 17 percent, respectively, and septic shock was the major cause of death. RESULTS: This study suggests that simple bowel obstruction is the fatal complication of A. lumbricoides infestation, which is seen particularly in pre-school and young school-aged children living in unhygienic conditions, and illustrates the need for heightened awareness of A. lumbricoides by the emergency physician in the differential diagnosis. CONCLUSIONS: Early diagnosis and surgical intervention are essential to minimize high morbidity and mortality.

Septic shock due to toxoplasmosis in patients infected with the human immunodeficiency virus.

PURPOSE: To describe the presentation and clinical course of septic shock due to Toxoplasma gondii in patients infected with the human immunodeficiency virus (HIV). PATIENTS AND METHODS: From April 1988 to February 1992, nine HIV-infected patients were admitted because of predominant septic shock (7 patients) or developed septic shock in the ICU (2 patients). The recent CD4+ cell count ranged from 2 to 84 x 10(6)/L. RESULTS: The main clinical features were (1) a history of fever for longer than 15 days, with a recent increase to more than 39.5 degrees C; (2) a recent history of dyspnea (< 15 days, 8 cases; < 7 days, 3 cases); and (3) recent onset of thrombocytopenia (6 of 9 cases). All patients were in shock (hyperkinetic profile in 6 of 7; hypokinetic in 1 of 7), and 8 of 9 were in respiratory distress (ratio of PaO2 over fractional concentration of oxygen in the inspired gas of 117 +/- 23; range, 88 to 155). Chest roentgenograms revealed diffuse alveolar infiltrates in six of nine cases. The serum lactate dehydrogenase (LDH) activity was 6,510 +/- 5,080 IU/L (range, 1,010 to 15,450 IU/L). Serologic tests for T gondii were negative in two cases. Toxoplasma gondii was isolated from lung (9/9), bone marrow (5/7), or blood (2/2). One, 3, and 2 patients had brain, ocular, and myocardial involvement, respectively. No other microbial pathogens were isolated. Seven patients died, 5 less than 3 days after admission. CONCLUSION: Disseminated toxoplasmosis can cause septic shock in HIV-infected patients. In two cases, the disease was probably a primary infection. The association of high fever, acute dyspnea, recent onset of thrombocytopenia, and a very high level of LDH activity is suggestive of disseminated toxoplasmosis.
