The authors report their experience of the clinical and echocardiographic aspects and course of tricuspid infectious endocarditis, based upon 12 cases collected between September 1985 and December 1992. The diagnosis was confirmed on the basis of the association of signs of septicemia (12 cases), at least two positive blood cultures for the same organism (9 cases) and well-defined vegetations seen by trans-thoracic echocardiography (12 cases). All patients were young women: mean age = 21.8 +/- 4.7. None were heroin addicts but one was positive for human immune deficiency virus. Tricuspid infectious endocarditis was most often acute (9 cases), primary (10 cases, post-abortum (11 cases), due to Staphylococcus aureus (5 cases), and complicated by cardiac failure (12 cases) and lung abscess (4 cases). Four patients died of septicemia (2 cases), of cardiac failure and lung abscess (2 cases). One had severe tricuspid incompetence requiring surgery. It has not yet been possible to operate on this patient because of the lack of cardiac surgery facilities in Congo. The prevention of tricuspid infectious endocarditis depends above all on the fight against clandestine abortions and against the development of intravenous drug abuse.

The incidence of infective endocarditis in drug addicts is increasing with the spread of intravenous drug abuse. The tricuspid valve is involved most commonly, followed by the mitral. We evaluated 22 patients prospectively with a mean age of 23 years, presenting with addiction-associated endocarditis and referred to our institution during a three-year period. The tricuspid valve was involved in 13 instances, the mitral in four, mitral plus tricuspid valves in five patients and the aortic valve in one. Staphylococcus aureus was the most frequent infective organism (15 cases), followed by streptococci (4 cases), corynebacteria (2 cases) and one case with a mixed infection. Six patients were HIV positive and 17 had evidence of chronic viral hepatitis. Ten patients (three of them HIV positive) were treated surgically. Resection of the tricuspid valve with (one case) or without replacement (four cases), resection of vegetations and tricuspid repair (two cases), mitral valve replacement (2 cases) and aortic valve replacement (one case) were performed. Operative mortality (< 30 days) was high (2/10, 20%); one patient died from cerebral hemorrhage and another from multi-organ failure. Another three patients died after a mean follow up of 10 months. In 12 patients, surgery was not attempted because of still existing intravenous drug abuse or renal and liver failure. Five of these patients died after a mean follow up of 13 months, two from septicemia, two from AIDS-related complications and one from drug overdose. The prognosis of drug-associated endocarditis treated with antibiotics is generally good.(ABSTRACT TRUNCATED AT 250 WORDS)

Cryofiltration apheresis (CA) is a specific therapy for treatment of patients with cryoglobulinemia. We evaluated the safety and efficacy of CA in patients with mixed cryoglobulinemia associated with hepatitis C. As reported previously, the Cryoglobulin Filter comprises a membrane module inside a refrigeration unit on-line with a Spectra Apheresis System (COBE, Denver, CO). The efficacy of cryofiltration was measured by comparing the sieving coefficient of cryoprecipitable proteins (CPP) to that of albumin and comparing the systemic CPP concentration ratio post to pre treatment. Five patients were enrolled in this study, and a minimum of 10 procedures were performed for each patient. The risk for hepatitis C was multiple blood transfusions, intravenous drug abuse, immunosuppressive therapy, or renal transplantation. Four patients had Type II mixed cryoglobulinemia, and one patient had Type III. Four patients had chronic renal failure; one with liver cirrhosis received alpha interferon along with CA. One patient had no response to conventional plasma exchange and immunosuppressive therapy secondary to repeated infections and sepsis; CA was the only viable therapy for this patient. The maximum CPP concentration before therapy ranged from 1,440 to 7,440 micrograms/ml. The plasma CPP sieving coefficient at 1 L filtrate ranged from 0.25 to 0.74 (average +/- SE, 0.51 +/- 0.19; n = 39). The sieving coefficient for albumin was 1 (n = 50). The systemic CPP ratio post to pre treatment ranged from 0.28 to 0.83 (average +/- SE, 0.59 +/- 0.20; n = 37). No adverse effects specific to CA were observed. The CA was safe and effective and possibly the only choice of therapy in patients with cryoglobulinemic hepatitis C who have no response to plasma exchange and immunosuppressive therapy.

We studied the infection rate of long-term intravenous access used for daily home treatment of cytomegalovirus (CMV) disease in 61 AIDS patients who had 75 central venous catheters implanted for antiviral maintenance therapy between February 1989 and December 1994. In 39 patients (64%) the risk factor for AIDS was intravenous drug abuse. Sixty-three catheters were Hickman type and 12 were totally implanted ports. The cumulative follow-up time was 19000 catheter-days (52 patient-years), with median duration of placement of 249 days. The infection rate was 0.22 infections per 100 catheter days. The probability of remaining free of catheter-related sepsis was 58% at 6 months. In 25 cases (61%) antimicrobial therapy without catheter removal was successful. Three patients died because of a catheter-related infection (mortality rate 7.3%). Infection-free survival time was not related to the risk factor for AIDS (p = 0.44) or type of device (p = 0.41). The total infection rate in these patients receiving daily home maintenance therapy for CMV disease through a long-term catheter was similar to that in other AIDS patients receiving weekly treatment in hospital facilities.

A 46-year-old Hispanic male with a history of intravenous drug abuse and sexual promiscuity received a cadaveric renal transplant in January 1984. He tested positive for HIV- 1 in February 1986. Infectious complications began 19 months after transplantation and were managed successfully until his death from sepsis 109 months posttransplant. Other HIV-infected long-term solid organ transplant survivors are reviewed from the literature. The effects of prednisone and cyclosporine on HIV- 1 expression are discussed briefly.

Primary renal mucormycosis is a rare infection capable of acute illness with sepsis. Few cases have been reported. We report a case of an acute primary renal mucormycosis and review the published reports. The incidence of primary renal mucormycosis has risen in recent years. The most frequently reported underlying predisposing disorders are human immunodeficiency virus infection, intravenous drug abuse, and diabetes mellitus. Primary renal mucormycosis should be suspected in patients with an immunocompromising illness or particular risk factors, when persistent flank pain and fever with sterile urine not responding to appropriate antibiotics are associated with enlarged heterogeneous kidneys.

Cholestasis in a patient with Hodgkin's disease is uncommon, and the causes of cholestasis are mainly direct tumor involvement of the liver, hepatotoxic effects of drugs, viral hepatitis, sepsis and opportunistic infections. Vanishing bile duct syndrome (VBDS) represents a very rare cause for cholestasis in this disease. We report here on a case of a 45-year-old man who developed VBDS during the complete remission stage of Hodgkin's lymphoma. There was no history of hepatitis or intravenous drug abuse, and the patient had negative results for hepatitis A virus, hepatitis B virus, hepatitis C virus, cytomegalovirus, and human immunodeficiency virus. The serological studies for antinuclear antibodies, anti-mitochondrial antibodies and anti-smooth muscle antibodies were also negative. Liver biopsy disclosed the absence of interlobular bile ducts in 9 of 10 portal tracts without any active lymphocyte infiltration and there were no Reed-Sternberg cell in the liver. The patient's cholestasis was in remission and the serum bililrubin level was normalized after two months without treatment, but tumor recurrence was noted at multiple sites of the abdominal lymph nodes on follow-up abdomino-pelvic computed tomogram.

Gemella morbillorum, a microaerophilic Gram-positive coccus, is a natural inhabitant of the human oropharyngeal, gastrointestinal and urogenital flora. However, it is an infrequently isolated organism and a rare cause of pulmonary or pleural infections. We report on a 26-y-old male subject with a past medical history of epilepsy and intravenous drug abuse, who presented with imminent sepsis and respiratory failure. Computed tomography of the thorax revealed a pleuropulmonary consolidation of the left lower lobe, and ultrasound guided thoracentesis resulted in aspiration of pus. Microbiological analysis revealed Gemella morbillorum in the pleural fluid. Thoracic drainage and antibiotic therapy resulted in full recovery. We discuss previous cases of pleuropulmonary infections due to Gemella morbillorum and review the available literature of this rare occurrence.

Infective endocarditis, a serious microbial infection of the cardiac endothelial surface, may involve any heart valve. However, right-sided endocarditis is uncommon in non-intravenous drug abusers without underlying heart disease, and the contextual involvement of the left-sided valve is exceptional. A 63-year-old man with no evidence of intravenous drug abuse or heart disease, presented with persistent fever, worsening of breath, and aphasia. His medical history was notable for mild arterial hypertension and serious lymphangitis with cutaneous erosions on the legs. Transesophageal echocardiography was performed for suspicious endocarditis and showed a pedunculated and highly mobile vegetation adhered to the atrial portion of the posterior leaflet of the mitral valve, protruding into the left ventricle through the valvar orifice. Another large vegetation was seen at the tricuspid valve surface and protruded into the right ventricle during diastole. Cerebral and thoraco-abdominal computed tomography scan revealed multiple embolism to the left kidney, spleen, lungs and central nervous system. Blood cultures identified Staphylococcus aureus. The only risk factor was large skin sepsis. Despite successful antibiotic therapy, the patient died for development of renal and respiratory failure.

Isolated endocarditis of the native pulmonary valve is a rare clinical condition. It usually appears in association with certain predisposing factors, particularly intravenous drug abuse, alcohol abuse, sepsis, endovascular infections or congenital heart disease. The authors describe the case of isolated pulmonary valve endocarditis due to Pseudomonas aeruginosa of possible nosocomial origin in the absence of the predisposing factors mentioned above. Native pulmonary valve infection due to Pseudomnzonas aeruginosa in the absence of predisposing factors has not been described in the literature. The authors stress the importance of diagnosing this entity as early as possible as it is associated with high mortality and is on the increase due to the growing number of invasive procedures applied to patients in the hospital environment.
