Abstract

We present the case of a patient with sepsis following a traumatic intra-bladder instillation of Calmette-Guerin Bacillus with pneumonia and possibly hepatitis. These complications are rare and could be induced by both immuno-allergic reaction and bacteremia. There is no specific guideline to treat this condition, but many clinicians depicting similar cases seem to agree on prolonged anti-tuberculous antibiotics with associated corticosteroid therapy. Following this therapy, the prognosis is generally favorable depending upon the fact that diagnosis has correctly been made. Our case highlights the fact that correct diagnosis has to be made especially in the presence of sepsis without a clear septic source.

Abstract

Lactic acidosis results from an acid-base balance disorder of the body due to an excess of lactic acid. It is frequently found in critically ill patients admitted to the intensive care. The most common cause is type A, found in pathologies such as cardiogenic, septic and hypovolemic shock, trauma and severe hypoxemia. The type B is less common and arises without evidence of tissue hypoperfusion or shock. Divers etiologies have been described for this type of hyperlactatemia: Grand Mal seizures, liver failure, hematologic malignancies, congenital enzyme deficiencies, thiamine deficiencies and diabetes mellitus and also alcohol abuse, which may induce a lactic acid under-use or an increased production. The authors describe a rare complication of type 1 Diabetes Mellitus (T1DM), leading to a major and persistent expression of a type B lactic acidosis during ketoacidosis.

Abstract

Gas gangrene (GG) remains a life-threatening and deadly disease. Early recognition together with daily surgical debridement remains the mainstay of therapy. We sought to describe a fatal case of necrotizing soft tissue infection, which was a gas gagrene in this case. This case was remarkable as two main sites were infected simultaneously in geographical zones very far from each other making dissemination between both sites almost impossible. The other particularity was the fact that the infection was caused at the same time by four different bacteria that is atypical in GG similar to that in streptoccocal necrotizing fasciitis where one bacteria is the causative agent (Clostridium perfringens for GG and group A streptococcus for necrotizing fasciitis).

Abstract

The authors describe two cases of metabolic acidosis, caused by diabetic ketoacidosis in the first case and by dehydration following gastroenteritis in the second one. Both patients were followed with noninvasive end-tidal CO2 (ETCO2) monitoring. A correlation between EtCO2 and PCO2 and HCO3− has been established in the literature. Noninvasive ETCO2 is used in only 5–6% of metabolic emergencies. In contrast, users described its use as easy and convenient.

Abstract

Background

Hemofiltration rate, changes in blood and ultrafiltration flow, and discrepancies between the prescribed and administered doses strongly influence pharmacokinetics (PK) and pharmacodynamics (PD) of antimicrobial agents during continuous veno-venous hemofiltration (CVVH) in critically ill patients.

Methods

Ancillary data were from the prospective multicenter IVOIRE (hIgh VOlume in Intensive caRE) study. High volume (HV, 70 mL/kg/h) was at random compared with standard volume (SV, 35 mL/kg/h) CVVH in septic shock patients with acute kidney injury (AKI). PK/PD parameters for all antimicrobial agents used in each patient were studied during five days.

Results

Antimicrobial treatment met efficacy targets for both percentage of time above the minimal inhibitory concentration and inhibitory quotient. A significant correlation was observed between the ultrafiltration flow and total systemic clearance (Spearman test: P < 0.005) and between CVVH clearance and drug elimination half-life (Spearman test: P < 0.005). All agents were easily filtered. Mean sieving coefficient ranged from 38.7% to 96.7%. Mean elimination half-life of all agents was significantly shorter during HV-CVVH (from 1.29 to 28.54 h) than during SV-CVVH (from 1.51 to 33.85 h) (P < 0.05).

Conclusions

This study confirms that CVVH influences the PK/PD behavior of most antimicrobial agents. Antimicrobial elimination was directly correlated with convection rate. Current antimicrobial dose recommendations will expose patients to underdosing and increase the risk for treatment failure and development of resistance. Dose recommendations are proposed for some major antibiotic and antifungal treatments in patients receiving at least 25 mL/kg/h CVVH.
