Legionnaires' Disease Complicated with Rhabdomyolysis and Acute Kidney Injury in an AIDS Patient.

1. Introduction

Legionella pneumophila (LP) infection is a recognized but rare cause of rhabdomyolysis [1, 2]. It can be further complicated with renal impairment which can be due to acute tubular necrosis (ATN) or acute tubulointerstitial nephritis (ATIN) [3]. This triad of pneumonia, renal failure, and rhabdomyolysis is associated with high morbidity and mortality [4]. We report a case of an immunocompromised patient with Legionella pneumonia complicated with acute kidney injury and rhabdomyolysis. He required dual antibiotics with levofloxacin and azithromycin, in addition to dialysis, and intensive care treatment. He made a full recoverywith normal renal function. After review of the relevant literature on reported cases of this uncommon triad of Legionella pneumonia, renal failure, and rhabdomyolysis, early diagnosis has been shown to have good clinical response. We advocate for timely transfer to the intensive care unit (ICU) and judicious use of dialysis in patients with complicated Legionella pneumophilia as the outcomes are good.

2. Case

A 51-year-old male with a past medical history of HIV, COPD, and hypertension presented with a four-day history of fever, shortness of breath, and nonproductive cough associated with headache and reduced appetite. He had a 30-pack-year history of smoking cigarettes and had not been compliant with his HIV medications as well as trimethoprimsulfamethoxazole. He had no history of nonsteroidal antiinflammatory drug (NSAID), herbal drug, or cocaine use. He denied recent ill contacts, recent travel, or camping. On examination, he was in respiratory distress with blood pressure 143/95 mmHg, pulse 135 beats per minute, respiratory rate 24 breaths per minute, temperature 39.5 degrees Celsius, and sPO2 92% on room air and 98% on 2 litres nasal cannula. He had bronchial breath sounds in the left mid and lower lung fields with crackles, but no wheezing. His heart sounds were normal. Abdomen was soft and nontender, with normal bowel sounds. Other aspects of his examination were unremarkable.

His white cell count was 4.6 (4.5-11 x [10.sup.3]/uL); haemoglobin was 10.7 (12-16 g/dL); platelet was 246 (140-440 thou/ cumm); mean corpuscular volume was 94 (82-101 fl); Prothrombin Time (PT) was 12.9 (11-13.5 seconds); international normalised ratio (INR) was 1.0 (0.8-1.2); partial thromboplastin time (PTT) was 34 (25-35 seconds); HbA1c was 5.7% (4-5.6%); procalcitonin was 31.2ng/mL (<0.15 ng/mL); thyroid stimulating hormone (TSH) was 0.705 (0.27-4.2 uIU-ml); sodium was 137 (135-145 mmol/L); potassium was 4.5 (3.3-4.6 mmol/L); chloride was 95 (101110 mmol/L); BUN was 56 (6-22mg/dL); creatine was 6.98 (0.6-1.17 mg/dL); calcium was 7.8 (8.6-10 mg/dL); albumin was 2.6 (3.8-4.9 g/dL); phosphorus was 5.5 (2.5-4.5 mg/dL); aspartate aminotransferase was 789 (14-33 IU/L); ALT was 235 (10-42 IU/L); anion gap was 22 (4-16); direct bilirubin was 3.3 (0-0.2 mg/dL); indirect bilirubin was 0.4 mg/dL (0.2-1.2 mg/dL); total bilirubin was 3.7 (0.2-1.0 mg/dL); alkaline phosphatase was 66 (40-129 IU/L); total creatine kinase was 51092 U/L (22-195 U/L), and urine was positive for myoglobin. His CD 4 count was 41 cells/ul, and HIV viral load was 34900 copies/mL.

Urine analysis with Alere BinaxNOW lateral flow immunochromatographic assay for Legionella antigen serogroup 1 was positive; urine pneumococcal antigen was negative; blood culture, respiratory culture, and urine culture were without bacterial growth; respiratory viral panel was reported negative for influenza, parainfluenza, rhinovirus, respiratory syncytial virus (RSV) virus, human metapneumovirus, H1, and H3.

His electrocardiogram showed sinus tachycardia. Chest X-ray (CXR) showed a homogenous consolidation in the left lower lung field (Figure 1). CT chest showed consolidation in the left lingual with air bronchograms consistent with lobar pneumonia, without pleural effusion (Figures 2 and 3). Echocardiograph showed a left ventricular ejection fraction of 65%. Renal ultrasound showed normal sized kidneys with normal echogenicity without hydronephrosis.

He was diagnosed with Legionella pneumonia, rhabdomyolysis, and acute renal failure and started on levofloxacin and atovaquone. He became further oliguric, with rising creatine and BUN, with worsening respiratory status requiring intubation and ventilation in addition to dialysis which were commenced on the second day of admission. Azithromycin was added to his antibiotic regimen in the ICU. His maximum creatine was 13.04 mg/dL, and BUN was 153 mg/dL during his hospital course. His respiratory and renal function improved during his ICU stay. He was extubated after six days. With improvement in his urine output and renal indices; he no longer required dialysis. On discharge, after 28 days of hospital stay and seven days of ICU stay, his creatine was 2.6 md/dL, BUN 36 md/dL, total creatine kinase (CK) 69 U/L, aspartate aminotransferase (AST) 16 IU/L, alanine aminotransferase (ALT) 30 IU/L, direct bilirubin 0.1 mg/dL, indirect bilirubin 0.1 mg/dL, and total bilirubin 0.2 mg/dL. After three-weeks follow-up in the outpatient setting, his creatine was back to normal at 1.06 (0.6-1.17 mg/dL), with resolution of the chest X-ray consolidation (Figure 4). Renal biopsy was not pursued in light of recovery of normal renal function.

3. Discussion

In adults, Legionella causes 2-15% of community acquired pneumonia (CAP) cases that require hospitalization [5]. It is the second most common cause of serious pneumonia that needs admission in an intensive care unit (ICU) [5]. The first report that associated Legionella and rhabdomyolysis was published in 1980 by Posner et al. [5] It is a recognized but rare cause of rhabdomyolysis [1, 2]; a clinical syndrome characterized by elevated serum concentrations of creatine phosphokinase (CPK) and myoglobinuria leading to renal dysfunction [17].

Renal impairment in Legionella pneumophila infection accompanied by rhabdomyolysis can be due to ATN or ATIN [3]. Legionellosis-associated ATIN could be either indirectly associated with Lpneumophila via rhabdomyolysis or directly affected by L pneumophila [3]. Interestingly, renal anomalies can develop days before the imaging demonstration of pneumonia [18].

Many of the laboratory findings are nonspecific and include renal and hepatic dysfunction, hyponatremia, hypophosphatemia, thrombocytopenia, leukocytosis, hematuria, and proteinuria [1]. The gold standard is culture and sensitivity on specialized charcoal media, which has a sensitivity of 70-80% [1]. However, this is not a rapid test and usually takes 3-5 days [1]. Urine antigen test is a rapid, practical, and inexpensive method for the diagnosis of the disease, characterized by sensitivities of 70-90% and specificities approaching 100% [4, 5]. In our case the use of urine antigen testing confirmed the etiology of the pneumonia.

From a search on PubMed and Google with the terms "Legionella", "rhabdomyolysis", and "renal failure" we analysed case reports (Table 1) of 16 patients with the triad of renal failure, rhabdomyolysis, and Legionella pneumonia with focus on CK levels, need for dialysis, intensive care admission, outcomes after treatment, and the use of quinolones, macrolides, or both.

Thirteen patients made full recovery, five of which were treated with a quinolone and macrolide, with the others having either a quinolone or macrolide as part of their treatment. Observational studies suggest that quinolones are more likely to achieve a favourable outcome in terms of patient survival and length of hospitalization [5]. Combined treatment is believed to be superior to monotherapy in cases of severe clinical disease or in immunosuppressed subjects [5]. In our case early treatment with a quinolone and macrolide led to good outcome.

Of the 16 patients analysed, 8 patients had CK levels greater than 5,000 U/L at presentation, with four out of those 8 having levels >20,000 U/L. Our patient also had a significantly high CK level at 51092 U/L. Considering that patients present to the hospital days after the onset of disease, this may give the bacteria sufficient time to cause muscle injury. The exact mechanism of muscle injury caused by Legionella is still unclear [19]. However, release of an endotoxin or exotoxin that causes rhabdomyolysis and direct bacterial invasion seem to be the most probable mechanisms [19]. In another report published in 1992 that studied renal failure in patients with Legionella disease, 8 patients had rhabdomyolysis out of 45 cases, three of which died; 2 of which did not undergo dialysis [6]. Physicians should always anticipate rhabdomyolysis and check for its presence in patients with Legionella disease, as early anticipation of this event and initiation of early aggressive fluid resuscitation are critical in reducing the risk of myoglobinuric acute kidney injury [20]. CK levels have been shown to correlate well with severity of rhabdomyolysis in some reports [21]. Furthermore, in one study of 1,769 adult patients, serum CK > 773 U/L correlated well with the onset of acute kidney injury (AKI) and rhabdomyolysis [21]. Many of the patients from our analysis in addition to our patient had the presence of renal impairment with CK levels > 773 U/L [22].

From our analysis of 16 patients, most cases required ICU care (10 cases). A 1998 study of 392 cases of community acquired pneumonia revealed 12.5% due to Legionella and 20.4% of those requiring ICU admission [1]. It is reported that chronic lung disease, immunodeficiency, malignancies, renal impairment, diabetes mellitus, nosocomial acquisition, and delayed initiation of specific antimicrobial therapy are associated with poor outcomes [5]. Our patient had four of these factors which could have predisposed him to a more severe course of Legionella disease. Additionally, it is reported that late but not early admission to the ICU for community acquired pneumonia is associated with poorer outcomes in comparison to patients managed on medical wards [23]. From our analysis, of the 10 patients admitted to the ICU, seven had good outcomes. Our patient also had a good recovery. It is important that there be early identification of patients who may develop severe Legionella pneumonia within the very first days of hospital stay to intensify the level of care and to propose early ICU transfer as the outcomes may be better.

From this review of 16 patients, most of these patients became progressively oliguric with worsening renal indices during their hospital course eventually requiring dialysis as seen in 12 of these cases. Our patient took a similar course despite aggressive fluid resuscitation. With this trend, frequent monitoring of renal indices and urine output is critical in patients with Legionella disease in light of the propensity for this disease to follow the path of eventually requiring dialysis, as seen in our case. The timing of initiating dialysis is a challenge and should not be determined solely by myoglobin or CK serum concentration but by the status of renal impairment, with complications such as life-threatening hyperkalemia, hypercalcemia, hyperazotemia, anuria, or hyperhydration without response [21].

It is generally accepted that patients with immune paresis, especially cell-mediated, are susceptible to Legionella infection [24]. Nevertheless, Legionella pneumophila is not commonly described in persons with infection due to human immunodeficiency virus (HIV) [25]. There is no clear relation between incidence of Legionella CAP and CD4 count [26, 27]. In a 10-year retrospective single center study, 15 cases of Legionella CAP were observed. When compared with pneumococcal CAP, disease was more severe with Legionella with a higher incidence of bilateral pneumonia, respiratory failure, and need for ventilatory support. Extra respiratory symptoms, hyponatremia, and increased creatine phosphokinase were more frequent in Legionella pneumonia [27]. Our patient was not compliant with prophylactic trimethoprimsulfamethoxazole (TMP-SMX). This drug has some activity against Legionella and in previous reports there is a low incidence of Legionella pneumonia in persons on TMPSMX prophylaxis [25]. Health professionals should have high suspicion for Legionella as a possible etiology for pneumonia, in AIDS patients with TMP-SMX noncompliance.

4. Conclusion

Consider Legionella pneumonia in patients presenting with rhabdomyolysis, renal failure, and respiratory symptoms. Early diagnosis and appropriate treatment have been shown to have good clinical response. Timely intensive care management, together with early and judicious use of dialysis, in patients complicated with rhabdomyolysis and renal failure may lead to good outcomes.
