Out of 1,251 patients above 65 years of age staying at the Charles Foix Hospital (prolonged hospitalization) and the St. Joseph Hospital (acute cases), 168 had one or more positive blood cultures. Urinary tract infection is a major source of septicemia due to gram negative bacilli. It is important to stress cases of septicemia due to pneumococcal pneumoniae, eschars, and other skin lesions. Mortality varies between 33 and 36%, depending upon the hospital. Collapse, although infrequent, still portends a grave prognosis (61% of cases of collapse led to death at Charles Foix Hospital). The combination of more than two risk factors considerably worsens the prognosis. Hypoproteinemia and dementia are every bit as grave as diabetes and cancer. A better isolation of the microorganisms involved in cases of septicemia in the elderly will lead to a more judicious choice of antibiotics. The administration of chemotherapy immediately after the samples were obtained remains the main guarantee of successful therapy.

Pseudomembranous enterocolitis is reported in five children. The clinical syndrome, characterized by the acute onset of profuse diarrhea, occurred postoperatively in 2 patients. All the patients had received or were taking antibiotics (penicillin, ampicillin, clindamycin). The disease was severe in 4 persons who presented with hypoproteinemia. Related complications were edema, ascites, pleural effusion, septicemia and/or shock. The diagnosis was made on the basis of typical rectosigmoidoscopic findings. Despite intensive therapy 2 children died. The use of parenteral nutrition is advocated in severe cases with exudative enteropathy. When profuse diarrhea occurs postoperatively or does not rapidly subside with discontinuation of antibiotic therapy, a high index of suspicion should be maintained, even in children, for the possibility of pseudomembranous enterocolitis. An emergency rectosigmoidoscopy should be done in order to make an early diagnosis.

To determine the importance of bacteremia in hospitalized patients with diarrhea in Bangladesh, from September 1982 through August 1983 the authors obtained blood for culture from 1,824 patients who were suspected of having sepsis (44% of all admissions). Nontyphoid bacteremia occurred in 243 patients. The most common pathogens were the Enterobacteriaceae (n = 66 episodes), Staphylococcus aureus (n = 65), Pseudomonas aeruginosa and other non-glucose-fermenting bacilli (n = 50), Streptococcus pneumoniae (n = 40), and Haemophilus influenzae (n = 16). When compared with an equal number of control patients without bacteremia, bacteremic patients were significantly (p less than 0.05) more likely to be under 1 year of age (46.5% of bacteremic patients vs. 30.0% of control patients) and more often had abdominal tenderness (20.1% vs. 11.5%), hypoproteinemia (a serum protein level less than 60 g/liter) (58.9% vs. 42.9%), and a prior intravenous infusion (49.0% vs. 30.9%). The case-fatality rate was 29.7% in bacteremic patients versus 7.8% in controls (relative risk (RR) = 3.8, p less than 0.001). Factors that were associated with an increased risk of death in bacteremic patients were infection with a Gram-negative pathogen (RR = 2.48), decreased peristalsis (RR = 2.66), hypoproteinemia (RR = 3.36), hypothermia (RR = 2.54), and hypotension (RR = 2.19). Bacteremia appears to be an important link between diarrheal illness and death in Bangladesh. In children with diarrhea who are suspected of being septic, early implementation of antimicrobial therapy that is effective against the broad range of pathogens identified appears to be indicated.

Fifty-four elderly patients with thermoregulatory failure were evaluated retrospectively. The most commonly associated cause was underlying sepsis, which occurred in 78% of cases. Underlying conditions that increased the incidence of hypothermia were hypoproteinemia (50%), cachexia (30%), and neuroleptic medications (21%), most commonly thioridazine. Digoxin toxicity was a common finding (20% of all cases). One third of the patients developed hypothermia in warm months and half of them developed it while in the hospital. Patients who presented with hypothermia from out of the hospital had lower temperatures, were more bradycardic and hemoconcentrated, and died more rapidly than the in-hospital group. This could be explained by lower outside temperature or delay in diagnosis and treatment of the underlying disease. The overall mortality rate was extremely high (74%) in both groups. The mortality rate was not affected by age, sex, or degree of hypothermia. We conclude that thermo-regulatory failure in the elderly can occur in warm as well as cold environments or climates. The development of hypothermia in elderly patients should be promptly treated as sepsis unless proven otherwise, in light of the poor prognosis of this condition.

To describe the epidemiologic and clinical features associated with invasive amebiasis in Bangladesh, 85 hospitalized diarrheal patients with hematophagous trophozoites of Entamoeba histolytica in their stools were compared to a control group of 84 hospitalized diarrheal patients without amebiasis. Postmortem examinations were carried out in 22 deaths due to amebiasis. For the patients with amebiasis, there was a bimodal age distribution with peaks at 2-3 years and greater than 40 years, whereas the control patients had a unimodal distribution with the peak at 0-1 year. The sex distribution was equal in childhood but young adults were predominantly female and older adults predominantly male. The clinical features significantly associated with amebiasis were prolonged dysentery, prior measles rash, malnutrition, hyponatremia, hypokalemia, and hypoproteinemia (all P less than 0.05). The case fatality rate in amebiasis was 29%, which was significantly higher than 11% for the controls (P less than 0.05). Postmortem findings included extensive colitis with deep ulcers and complications, including colonic perforation in 2 cases, peritonitis in 4 cases, pneumonia in 9 cases, and septicemia in 5 cases. These results indicate that invasive amebiasis in this population differs from other diarrheal diseases, affecting mainly children greater than 2 years and adults and causing severe and fatal illness characterized by extensive colitis with diverse systemic consequences.

The pathophysiology of renal dysfunction in generalized sepsis remains unknown. In this study, 24 hours after surgical induction of peritonitis in 20 volume-loaded sheep, three patterns of renal function were seen. In group 1 (n = 8), glomerular filtration rate (GFR) decreased by 70%, urine volume by 85%, absolute sodium excretion by 95%, and fractional sodium excretion by 83%. Group 2 (n = 4) exhibited similar sodium retention but GFR did not fall. Group 3 (n = 8) showed no change in GFR or urine volume and only minimally reduced sodium excretion. Mean arterial pressure fell 17% in group 1 only; central venous pressure, pulmonary capillary wedge pressure, and plasma volume were maintained at or above presepsis values in all groups. Cardiac index was either increased or unchanged, and renal plasma flow was maintained in all groups; there was thus no hemodynamic evidence to suggest volume contraction. Histologic examination showed only minor changes with no consistent pattern. Renal functional changes correlated with other manifestations of severe sepsis--GFR and sodium retention correlated significantly with increased cardiac index, decreased systemic vascular resistance, pulmonary arterial hypertension, leukopenia, hypoproteinemia, and hypoglycemia. All of these changes were most marked in group 1. In groups 1 and 2, plasma renin activity (PRA) increased and urinary kallikrein excretion decreased. PRA correlated inversely with GFR, urine volume, and sodium excretion; urinary kallikrein excretion correlated positively with urine volume and sodium excretion. Urinary excretion of 6-keto-PGF1 alpha was increased in groups 1 and 2 and correlated inversely with mean arterial pressure in group 1 animals. During sepsis, urinary thromboxane B2 excretion continued at presepsis values in all groups. The results suggest that unusual reciprocal changes in activity of the renin-angiotensin and renal kallikrein-kinin systems may play a role in the renal response to sepsis. PGI2 synthesis is increased and may affect systemic hemodynamics and renal function; the role of thromboxane A2 in this context is unknown.

Toxic epidermal necrolysis resulting from severe hypersensitivity to medication has a reported mortality of up to 66%. A patient surviving two episodes with more than a 50% skin loss is unprecedented in the medical literature. Mortality has been associated with many factors, including delayed reepithelialization, persistent skin slough, coagulopathy, severe hypoproteinemia, and sepsis. It may be possible to decrease morbidity and mortality by preventing the shearing of epidermis, thereby limiting the denuded areas. This case report describes the successful management of our patient's second episode of toxic epidermal necrolysis. The treatment of this patient in our specialized burn center consisted of careful fluid and electrolyte management, nutritional support, standard topical antimicrobials, and new modalities of local wound management.

A simian acquired immunodeficiency syndrome (SAIDS) associated with retroperitoneal fibromatosis (RF) has been observed in several species of macaque at the Washington Regional Primate Research Center. Clinical signs were recurrent diarrhea, weight loss, mesenteric lymphadenopathy, and opportunistic infections. Most affected macaques in the later stages of illness showed marked immunodeficiency. Response of peripheral blood mononuclear cells to mitogens was impaired significantly. There was sharply depressed primary and secondary antibody response to the T-cell dependent antigen, bacteriophage phi X174. Affected monkeys did not switch from IgM to IgG antibody following a secondary immunization, as did normal macaques. Twenty-four (67%) of 36 affected animals with progressive RF or deteriorated stages of illness had hypoproteinemia and hypoalbuminemia. Quantitative serum immunoglobulins of 23 cases showed that eight (35%) had hypogammaglobulinemia, six (26%) had hypergammaglobulinemia, and the remainder (39%) were within the normal range. Opportunistic infections were predominantly bacterial pathogens. Type D retrovirus appeared to be closely associated with RF-affected macaques (12/12 or 100%). The case fatality rate (including animals sacrificed after prolonged illness) was 98%. The leading cause of death was due directly to RF lesions in 43%, to enterocolitis in 36%, septicemia in 12%, amyloidosis in 5%, and malignant lymphoma (2%). Clinical, immunologic and pathologic changes reveal an acquired immunodeficiency syndrome that has many similarities to human AIDS. SAIDS and RF may be a useful model for studying human AIDS.

The aetiology, pathogenesis, diagnosis and therapy of sepsis are dealt with in this paper. These problems are discussed on the basis of 151 patients treated for sepsis. The cases with monoinfection are 73.6% and those with polyinfection are 24.4%. Monoinfection is caused mainly by Staphylococci -65,3%, followed by E. coli - 15.2%, Proteus - 13% and Klebsiella - 3.3%. For the cases of polyinfection the gram-negative bacteria are 3:1 in respect to the gram-positive bacteria. The bacteriological finding from the haemoculture (92.8% mono- and 7.2% polyinfection) is not equal to this from the input source. Here also the cases of monoinfection are mainly caused by Staphylococci - 70.9%, followed by Proteus - 7.7%, E. coli - 6%, Klebsiella aerogenes - 5.1% and Streptococcus 2.6%. The gram-negative bacteria prevail in the cases of polyinfection. The virulent aggressive infection, bacteria resistant to antibiotics, the aggressive local infection, hypoproteinemia, anaemia, diabetes, a prolonged corticosteroid treatment and unsuitable antibiotic treatment are discussed as main factors predisposing to sepsis. All the 151 patients were treated with the complex therapy, recommended in this paper. It includes a surgical cleaning-up of the initial nidus, intensive reasonable antibiotic treatment against the gram-positive and gram-negative aerobes and anaerobes. Additionally, substitution of infusion therapy, parenteral nutrition, regulation of the pathophysiological deviations and stimulating therapy are carried out. 74.2% from the patients were cured, 25.8% died. 16.6% of the patients who died had sepsis caused by gram-positive bacteria, and 46.1% had sepsis caused by gram-negative bacteria. 17% of the patients who died had septicaemia and 22% had septicopyaemia.(ABSTRACT TRUNCATED AT 250 WORDS)

Peripheral edema, hypoproteinemia, and increased fluid requirements are characteristically seen with sepsis. Our purpose was to determine whether the soft tissue edema is caused by a direct vascular injury from sepsis or is secondary to hypoproteinemia. We determined the effect of endotoxin on peripheral (soft tissue) microvascular integrity using lymph flow (QL) and lymph/plasma (L/P) protein ratio to reflect fluid flux and increased permeability. Response was compared with that seen in the lung. Fourteen unanesthetized sheep were given intravenous E. coli endotoxin 2 micrograms/kg. Vascular pressures and cardiac output (CO) were maintained constant with the necessary fluid infusion. Lung QL increased two- to fourfold in all animals with lymph being protein-rich, indicating increased permeability. Peripheral QL increased transiently in response to an initial increase in vascular pressure returning rapidly to baseline except in those animals (N = 5) demonstrating hypoproteinemia where QL remained increased by 50 to 75%. The increased QL was totally explained by the degree of protein depletion, with no evidence of increased permeability. To assure an adequate endotoxin exposure to the peripheral microvessels, endotoxin (2 micrograms/kg) was also directly injected into the tissue drained by the soft tissue lymphatic. We noted a characteristic endotoxin pulmonary hypertension phase but, again, no increase in peripheral microvascular permeability was found. We conclude that endotoxemia does not alter peripheral microvascular permeability if tissue perfusion is maintained, while the lung is clearly a target organ. Hypoproteinemia may be responsible for the early edema in soft tissues with sepsis.
