The case of a 26-year-old man with pneumonia due to Legionella pneumophila associated with acute renal failure is presented, and the English-language literature on legionnaires' disease is reviewed. For this review, acute renal failure was defined as rapid deterioration in renal function indicated by a rise in levels of blood urea nitrogen and creatinine with or without the presence of oliguria. Our patient experienced renal failure and underwent hemodialysis. His condition gradually improved after treatment of legionnaires' disease with erythromycin. Biopsy of the kidney showed acute tubulointerstitial nephritis. Immunofluorescence microscopy demonstrated the presence of L. pneumophila serogroup 1. The laboratory findings suggested rhabdomyolysis. To our knowledge, this is the first case report of a patient with legionnaires' disease who recovered from acute renal failure and in whom the presence of L. pneumophila was demonstrated, and we believe it is the first case in which morphology of the kidney demonstrated the presence of L. pneumophila in a patient with legionnaires' disease, rhabdomyolysis, and renal failure.

It has been suggested that tubular-interstitial damage may be the main cause of Legionnaires disease (LD) associated acute renal failure (ARF). However, this hypothesis has rarely been examined. In China we firstly describe four patients with LD-ARF, who had proteinuria, hematuria, Leukocyturia and cylindruria. Two patients had nephrotic syndrome indicating acute glomerular injure, one of them was histopathologically proven to be rapidly progressive glomerulonephritis. Scr, UNa, RFI and FENa are markedly increased. Our results suggest that both tubular-interstitial and glomerular damage may be the important causes of LD-ARF in Chinese LD patients. To confirm this hypothesis further investigation are needed.

A case report is presented of a young man admitted to a general hospital with leukocytosis, elevated temperature, right lower lobe infiltrate, and confusion. A diagnosis of rhabdomyolysis, acute renal failure, and Legionnaire's disease was made. The patient subsequently had a respiratory arrest and died on the 29th hospital day. This triad is currently an enigma in the field of internal medicine. The diagnosis of each entity is elusive, and in many cases must be made by the astute clinician. Diagnostic features along with early intervention measures and their expected outcomes are discussed. Recognition of the interrelationship of these diseases, risk factors, and vague clinical presentations might allow further prospective intervention methods and diagnostic procedures to be undertaken to avoid the fatal consequences seen in this disease triad.

A patient is described who developed cavitary Legionella pneumonia 2 weeks after kidney transplantation. The initial pulmonary symptoms were followed by severe thrombocytopenia and acute renal failure. Although acute irreversible graft rejection was suspected, this was not supported by the pathology findings in the resected kidney, which were compatible with tubular damage. We presume that the extrapulmonary symptoms were caused by Legionellosis.

The number of different Legionella species is increasing at an impressive rate. In two prospective studies, one involving 110 intensive-care unit (ICU) patients with mainly nosocomial pneumonias and the other 105 patients with community-acquired pneumonias, we investigated the incidence and significance of Legionella pneumophila and non-pneumophila pneumonias on the basis of 17 different main serogroups. In the first study, 14 ICU patients had 15 (13.6%) Legionella pneumonias, which, in 5 cases (33%), were of non-pneumophila etiology. In the second study, 9 patients with community-acquired pneumonias had 10 (9.5%) Legionella pneumonias. Leading this study were 6 L. gormanii infections, followed by 2 L. dumoffii and only 1 L. pneumophila and 1 L. longbeachae pneumonia. Of the total, 22 of 23 patients with Legionnaires' disease suffered from severe basic diseases and complications (acute renal failure, respiratory insufficiency, etc.) predominant among the nosocomial pneumonias. The mortality rate was significant in these patients at 33% (5 patients) in the ICU group and 10% (1 patient) in the group with community-acquired pneumonias. We conclude that non-pneumophila Legionella species should receive more diagnostic and therapeutic consideration in patients with nosocomial or community-acquired pneumonias.

Renal involvement is a well described complication of Legionnaires' disease and is often manifested as mild, transient azotemia, hematuria, proteinuria, pyuria or cylinduria. Acute renal failure complicating Legionnaires' disease has also been described, and some patients have required hemodialysis. Renal morphology has only been described in a few cases. We report two cases of Legionnaires' disease who developed acute renal failure. The serotype of the Legionella pneumophilia isolated from one of the patients had never been isolated from humans before. This patient expired and at autopsy the kidney revealed acute tubular necrosis, but there was no evidence for interstitial or glomerular disease. Renal morphology in six previously reported cases revealed acute tubulointerstitial nephritis in three cases and acute tubular necrosis in the other three. We conclude that acute renal failure may accompany severe Legionnaires' disease, and the development of the renal failure is not related to hemodynamic factors, while nephrotoxic antibiotics may be a contributing factor.

Although the clinical and biochemical features of renal involvement in Legionnaires' disease have been well described, only a few case reports detailed the histological changes. A patient with Legionnaires' disease who developed acute renal failure is described; a biopsy specimen revealed mesangial proliferative glomerulonephritis. The renal morphological changes in Legionnaires' disease are reviewed.

Two cases of Legionnaires' disease proven by seroconversion in indirect immunofluorescence are reported. Creatine phosphokinase (CPK) was increased in both patients, and one had rhabdomyolysis with acute renal failure and acute respiratory distress. A review of the literature brought out 9 other cases of rhabdomyolysis associated with Legionnaires' disease. Myalgias are an inconstant warning symptom; renal impairment is present in more than one half of the cases, and although pulmonary lesions are moderate, respiratory muscle involvement may require mechanical ventilation. In view of the severe complications of rhabdomyolysis, CPK should be systematically assayed in patients with Legionnaires' disease; 57 p. 100 of whom, according to published reports, have high CPK levels. In a retrospective study of bacterial pneumonia caused by common pathogens, we found that CPK was elevated in 31 p. 100 of the cases. The mechanism of muscular involvement is discussed.

In a prospective study (from April, 1980 to April, 1981) of 110 patients with moderately severe to severe pneumonia 11 were found to have 12 manifestations of Legionnaires' disease. Diagnosis was proven by indirect immunofluorescence tests, either a quadruple titre rise to 1 : 128 or a single titre of at least 1 : 256. The clinical picture in all 11 patients was the typical one of severe pneumonia, usually involving the lower lobes, high fever between 39 and 40.4 degrees C, as well as WBC counts between 6.8 and 28.9 X 10(9)/l. In nine cases artificial ventilation was required, in four there was acute renal failure requiring dialysis, in four other definite renal insufficiency. All patients had underlying disease, in some severe, such as chronic obstructive lung disease, diabetes mellitus, heart failure, liver cirrhosis, renal transplantation or extensive operations. Eight patients died, four of them of Legionnaires; disease. The relatively high infection rate (10%) indicates that in patients with risk factors, as well as those with a pneumonia unresponsive to the standard treatment within five to seven days, Legionnaires' disease should be considered in the differential diagnosis.

An acute interstitial nephritis was found in a patient with sudden renal failure and lung infection caused by Legionella pneumophilia. Our patient regained and maintained normal renal function after a short period of dialysis support. The diagnosis should be considered in any patient with a chest infection complicated by acute renal failure especially if confusion is disproportionate to the degree of uremia.
