Primary human immunodeficiency virus type 1 infection in a patient with acute rhabdomyolysis

Primary human immunodeficiency virus type 1 (HIV-1) infection (acute retroviral syndrome) has been well characterized as a mononucleosis-like illness. Manifestations of HIV-1 infection such as pharyngitis, fever, morbilliform rash, myalgias, arthralgias, nausea, headache, emesis, and lymphadenopathy have been reported. Acute rhabdomyolysis has been reported as part of the acute retroviral syndrome on 11 different occasions. We report the case of a primary HIV-1 infection with acute rhabdomyolysis and review critically the other case reports.     

Rhabdomyolysis associated with acute renal failure in patients with severe acute respiratory syndrome

An outbreak of severe acute respiratory syndrome (SARS) occurred in Taiwan in 2003. SARS complicated with rhabdomyolysis has rarely been reported. This study reported three cases of rhabdomyolysis developing during the clinical course of SARS. Thirty probable SARS patients were admitted to the isolation wards at Linkou Chang Gung Memorial Hospital between 4 April and 4 June 2003. Thirty patients, including four men and 26 women aged from 12 to 87 years (mean age 40). Eleven (36.7%) patients had respiratory failure and required mechanical ventilation with paralytic therapy; three (10%) patients had rhabdomyolysis complicated with acute renal failure and one received haemodialysis; four (13.3%) patients died. Three cases with rhabdomyolysis all received sedative and paralytic therapy for mechanical ventilation. Haemodialysis was performed on one patient. Two patients died from multiple organ failure, and one patient fully recovered from rhabdomyolysis with acute renal failure. SARS is a serious respiratory illness, and its aetiology is a novel coronavirus. Rhabdomyolysis resulting from SARS virus infection was strongly suspected. Immobilisation under paralytic therapy and steroids may also be important in developing rhabdomyolysis.     

Rhabdomyolysis and renal failure associated with gemfibrozil monotherapy

OBJECTIVE: To report a case of rhabdomyolysis and acute renal failure associated with gemfibrozil monotherapy of hyperlipidemia. CASE SUMMARY: A 30-year-old white man with hypertension, type 1 diabetes mellitus, and hyperlipidemia was hospitalized due to myalgias, nausea, and vomiting that began after he started working as a jackhammer operator 4 days previously. His medications were lisinopril, aspirin, insulin, and gemfibrozil. Creatine kinase and creatinine, which previously had been mildly elevated and normal, respectively, were markedly elevated, consistent with rhabdomyolysis with acute renal failure. DISCUSSION: As of December 8, 2003, this is the only report of a patient with normal baseline creatinine level who developed rhabdomyolysis with acute renal failure associated with gemfibrozil monotherapy. Strenuous exertion, hypovolemia, and lisinopril use may have contributed to the severity of illness. An objective causality assessment revealed that an adverse drug reaction to gemfibrozil was possible. CONCLUSIONS: Gemfibrozil monotherapy of hyperlipidemia may predispose to rhabdomyolysis with acute renal failure. Patients using gemfibrozil should be cautioned regarding strenuous exertion, dehydration, and the need for prompt evaluation of myalgias.     

Early identification of leptospirosis as an ignored cause of multiple organ dysfunction syndrome

Leptospirosis is the most common zoonosis in the world but remains underreported, owing to protean manifestations and ignorance about the disease among health care providers in Taiwan. From September 2000 to March 2006, surveillance of 455 patients with multiple organ dysfunction syndrome with unclear cause or clinical suspicion of leptospirosis was performed. Diagnosis was further confirmed by microscopic agglutination test or isolation of Leptospira. Cases were classified as excluded based on confirmed etiology other than leptospirosis or negative paired serologic test. Forty-two patients were confirmed as having leptospirosis, which accounted for 9.2% of total patients with multiple organ dysfunction syndrome. Forty-nine excluded cases were identified for a case-control analysis for clinical distinction. The most common presentations of leptospirosis were fever (97.6%), acute kidney injury (85.7%), and jaundice (61.9%). The leptospirosis group showed lower urine specific gravity (cutoff value, 1.0145) and enlarged kidney size (cutoff value, 11.05 cm) as compared with the excluded cases by multivariate logistics regression. Delayed antibiotic administration prolongs the duration of hospitalization (R2 = 0.486, P < 0.01). No mortality has been found in the leptospirosis group after initiation in 2003 of rapid immunoglobulin M serology assay that showed considerably high sensitivity and specificity. Leptospirosis accounts for a salient cause of multiple organ dysfunctions in Taiwan. Early awareness of leptospirosis by distinct presentations, followed by prompt antibiotics therapy, can dramatically save the patients. The easily performed rapid immunoglobulin M serology assay is suitable as a rapid screening test for the diagnosis of leptospirosis.     

A point-source epidemic of leptospirosis. Description of cases, cause, and prevention

Leptospirosis is a zoonotic disease that consists of fever, headache, myalgias, and multiple organ involvement, has varying clinical severity and morbidity, and can occur in epidemic form. Diagnosis is based on culture or serologic demonstration of recent infection. There is evidence that doxycycline therapy started early in the course of the disease favorably affects duration and severity. Antibiotic therapy is often initiated because of a strong suspicion of the disease, before bacteriologic or serologic confirmation of the diagnosis is completed. Public health measures play an important role in minimizing the incidence of leptospirosis.     

Severe leptospirosis: treatment with intravenous corticosteroids and supportive care

Leptospirosis is a common zoonotic infection worldwide and is recognized as an emerging public health problem. Although commonly thought of as a tropical disease, incidence in temperate climates is increasing, with recent outbreaks in the United States and Germany, among other countries. The disease presents with symptoms ranging from fever, headache, nausea, and vomiting to life-threatening multiorgan failure characterized by acute liver failure, nephritis, pulmonary hemorrhage, meningitis, and cardiac arrhythmia. We describe a case of an otherwise healthy 28-year-old man who had just returned from a 2-month trip to Southeast Asia. He presented to our emergency department twice after his return with the complaint of fever and malaise. Initially, he was treated with symptomatic measures and discharged home with malaria smears and blood cultures pending. On his final presentation before admission, he presented with severe fatigue, myalgia, acute renal failure, and marked thrombocytopenia. After several days, inpatient testing revealed the patient's leptospira antibody titer was markedly positive. Given the nonspecificity of patient symptoms, early diagnosis of leptospirosis can be challenging. Diagnostic uncertainty may lead to delay in recommended intravenous antibiotic treatment. We present a case of severe leptospirosis treated exclusively with supportive measures and intravenous corticosteroids.     

Legionella pneumonia presenting with rhabdomyolysis and acute renal failure: a case report

Legionella pneumophila infection is a recognized but rare cause of rhabdomyolysis. While the mechanism of rhabdomyolysis associated with Legionella is unknown, theories include direct invasion of Legionella into the muscle itself, or the release of its endotoxin into the circulation with subsequent muscle injury. In this case report, we describe a case of Legionella pneumonia presenting as altered mental status, high fever, and rhabdomyolysis with acute renal failure. We review the epidemiology, clinical and laboratory findings, and treatment of the disease.     

Acute bacterial meningitis in children and adults. A perspective

Bacterial meningitis is an acute and serious illness associated with significant morbidity and mortality. Although methods to make the diagnosis are relatively simple and effective antimicrobial agents are available, bacterial meningitis accounts for more than 2000 reported deaths per year in the United States. The majority of cases and deaths occur in otherwise healthy individuals.     

Nontraumatic pneumocephalus due to nosocomial Enterobacter cloacae infection

Nosocomial meningitis is rare, and routine cerebrospinal fluid study is seldom recommended for hospitalized patients with fever and acute delirium. We present a case of Enterobacter cloacae meningitis complicated with a nontraumatic pneumocephalus. Maintaining a high index of suspicion of nosocomial meningitis is crucial in patients with acute delirium and multiple underlying comorbid conditions.     

Secondary headache in children

Headache is one of the common symptoms of fever and headache without fever is also not rare in general pediatric clinics. The common causes of these headaches involve extracranial infection due to viral illness, migraine and trauma. Headache with vomiting, fever and meningeal signs suggests meningitis. Taking blood pressure is necessary, even though headache caused by hypertension is rare in children. Neuroimaging should be performed with abnormal neurological findings, atypical headache pattern, or significant change of preexisting headache. Serious underlying diseases, such as brain tumor or intracranial hemorrhage, are uncommon, however they should be diagnosed immediately using neuroimaging because of their urgency.     

Acute renal failure due to leptospirosis: clinical features and outcome in six cases

Six cases of severe leptospiral infection with renal failure are described. Five of the six patients had acute oliguric renal failure requiring dialysis. Renal function recovered over three weeks and by two months all patients had plasma creatinine levels less than 200 mumol/litre. The initial diagnosis of leptospirosis depended on clinical and epidemiological features because serological confirmation was not possible during the first week of the illness. All the patients had either high risk occupations or a history of exposure to external sources of infection. All had fever, myalgia, jaundice and muscle tenderness. Although bilirubin levels were high (greater than 350 mumol/litre in five) the elevations of aspartate transaminase and alkaline phosphatase levels, and prolongations of prothrombin times were relatively slight. Thrombocytopenia occurred in five of the six cases. Leptospira complement fixation tests were weakly positive or negative on admission in five cases but rose to significant levels subsequently. Penicillin treatment resulted in Jarisch-Herxheimer reactions in three cases. The important complications were: upper gastro-intestinal haemorrhage (five cases), thrombocytopenia less than 30 000 platelets/mm3 (four cases), atrial fibrillation (three cases), drowsiness with asterixis (four cases). All six patients were seriously ill and required intensive supportive therapy. All survived.     

Rare case of severe rhabdomyolysis secondary to human granulocytic anaplasmosis

Anaplasma phagocytophilum (AP) is the causative agent of human granulocytic anaplasmosis (HGA), a tick-borne illness with highest incidence in north-eastern regions of the United States. This condition presents with vague constitutional symptoms and has been associated with laboratory derangements such as leukopenia, thrombocytopenia and transaminitis1. Rhabdomyolysis, however, is not one of these associations. We report a case of confirmed HGA associated with severe rhabdomyolysis, where no other cause was identified. The etiology of rhabdomyolysis secondary to AP infection is still unknown. A presumptive diagnosis of HGA can be made in the presence of fever, non-specific symptoms such as myalgias, laboratory derangements such as leukopenia and thrombocytopenia in an individual residing in an endemic area3. Serological confirmation should not delay treatment, given the rapid progression of this dangerous infection. Rhabdomyolysis should also be considered as part of supporting data in the diagnostic consideration for HGA.     

Acute rhabdomyolysis following viral infection with coxsackie A4 in a 50-day-old infant with Fukuyama congenital muscular dystrophy

BackgroundFukuyama congenital muscular dystrophy (FCMD), which is characterized by generalized muscle weakness, hypotonia, and motor delay during early infancy, gradually progresses with advanced age. Although acute rhabdomyolysis following infection in patients with FCMD has occasionally been reported, no studies have investigated rhabdomyolysis following viral infection in FCMD patients during early infancy.Case reportWe report the case of a 50-day-old girl with no apparent symptoms of muscular dystrophy who developed severe acute rhabdomyolysis caused by viral infection, resulting in quadriplegia and respiratory failure therefore requiring mechanical ventilation. Brain magnetic resonance imaging incidentally showed the typical characteristics of FCMD, and FCMD was confirmed by genetic analysis, which revealed a 3-kb retrotransposon insertion in one allele of the fukutin gene and a deep intronic splicing variant in intron 5 in another allele. The virus etiology was confirmed to be Coxsackie A4.ConclusionWe report a severe case of acute rhabdomyolysis with the earliest onset of symptoms due to the Coxsackie A4 virus in a patient with FCMD. The present findings indicate that physicians should consider FCMD with viral infection a differential diagnosis if the patient presents with acute rhabdomyolysis following a fever.     

Multiple organ dysfunction and rhabdomyolysis associated with moonwort poisoning: Report of four cases

BACKGROUND Moonwort is a widely used Chinese herbal medicine. It has various pharmacological effects, such as relieving cough and preventing asthma. To date,multiple organ dysfunction and rhabdomyolysis caused by moonwort poisoning have not been reported.CASE SUMMARY Here we report four cases of moonwort poisoning that presented with multiple organ dysfunction and rhabdomyolysis accompanied by vomiting, fatigue, and muscle aches. One patient was an adult male, two were adult females, and one was a boy, with an age range of 7–64 years. The adults were treated with hemoperfusion and symptomatic therapies, while the child was treated with plasma exchange and symptomatic therapies. All four patients recovered.CONCLUSION Blood purification combined with symptomatic treatment may be an effective method for managing multiple organ dysfunction and rhabdomyolysis caused by acute moonwort poisoning.     

Salmonella meningitis in an immunocompetent adult

Non-enteric salmonella infections in immunocompetent adults are exceedingly rare in the United States, and meningitis is one of the least common extra-intestinal sites. In addition, it is very unusual for a patient with bacterial meningitis to present with classic meningitis signs and symptoms of > 72 h duration. The objective of this work is to describe a rare case of salmonella meningitis in an immunocompetent adult and, in the context of previously published case reports, describe the frequently atypical clinical course of salmonella meningitis along with the potential pitfalls encountered during its evaluation and treatment. An otherwise healthy 45-year-old man presented to our Emergency Department with frontal headache, fever, and stiff neck of 7 days duration. He was alert and oriented in triage, where he was noted to be afebrile, mildly tachycardic, with a normal blood pressure and respiratory rate; shortly after triage he developed a high fever, severe tachycardia, hypotension, and a change in mental status. He was resuscitated according to our severe sepsis protocol and treated empirically for bacterial meningitis. Blood and cerebrospinal fluid cultures grew group D Salmonella berta. An evaluation for underlying immunodeficiency was unrevealing. The patient was discharged home on hospital day 7 in good condition. Salmonella meningitis can present with an indolent course and can mimic, in many misleading ways, the less serious diagnosis of aseptic meningitis. This case highlights the need for an unbiased clinical assessment, aggressive management of critical illness, and point-for-point correspondence between clinical data and assigned diagnosis.     

Severe scrub typhus infection: Clinical features,diagnostic challenges and management

Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay(IFA) for the detection of Ig M antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%.     

SARS-CoV-2 infection presenting as rhabdomyolysis: case report and review

Coronavirus disease 2019 (COVID-19) is the health crisis of our time and a great challenge we face, requiring the implementation of worldwide general containment. The symptoms and complications of COVID-19 are diverse, and rhabdomyolysis is an atypical manifestation. We report a case of a 63-year-old patient, admitted to the emergency room for myalgia and fever evolving over 5 days, in whom laboratory and other examinations indicated rhabdomyolysis complicated by renal insufficiency. During the diagnostic workup, the real-time polymerase chain reaction (RT-PCR) test result for COVID-19 was positive, revealing infection with sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the severity of COVID-19 infection relates mainly to acute respiratory syndrome, other complications can be prognostic, and these complications make the management of this disease difficult. Rhabdomyolysis is one of the fatal complications; first, because the pathophysiological mechanism is not yet understood, and second, because rhabdomyolysis, itself, is usually complicated by acute renal failure. This complication makes the disease management difficult, especially in patients with SARS. Rhabdomyolysis during COVID-19 infection represents a significant challenge, given the few reported cases, and further research is required to develop a therapeutic consensus.     

Brucella meningitis

A 36-year-old Hispanic man came into the emergency department with nonspecific symptoms (headache, myalgias, low-grade temperature, and low white blood cell count) and was diagnosed with brucella meningitis. The patient said he had consumed unpasteurized goat's milk and cheese in Mexico, and had been treated 3 months previously for a febrile illness diagnosed as Malta fever (brucellosis). Cultures of both the blood and cerebrospinal fluid yielded Brucella melitensis. Blood agglutinin results for B abortus were positive at greater than 1:160. Unpasteurized milk and cheese are consumed in many countries where brucellosis is endemic. Emergency physicians are occasionally confronted with patients from developing countries with diseases that require rapid and specific diagnosis for optimal treatment.     

Recurrent arthralgias in a patient with previous Mayaro fever infection

Mayaro fever is an acute, self-limited, febrile, mosquito-borne viral disease manifested by fever, chills, headache, myalgias, and arthralgias. The virus belongs to the family Togaviridae and the genus Alphavirus. Five other mosquito-borne viruses have been described as causing a similar dengue-like illness. The virus was first isolated in 1954, and the first epidemics were described in 1955 in Brazil and Bolivia. Other cases have been reported in Suriname, Brazil, Peru, French Guiana, and Trinidad. Up to 10 to 15% of febrile illnesses in endemic areas have been attributed to Mayaro virus. The exact pathogenesis and pathophysiology among humans is unknown. Animal models have demonstrated necrosis of skeletal muscle, periosteum, perichondrial tissues, and evidence of meningitis and encephalitis. All previous cases of Mayaro fever describe a self-limited illness. No reports of recurrent symptoms exist in the literature. This report describes a case of recurrent arthralgias in a military service member presenting to the emergency department.     

Japanese spotted fever associated with multiorgan failure

A 49-year-old man was admitted to our hospital, with a diagnosis of multiple organ failure, on June 10, 2000. Physical examination revealed high fever, generalized maculopapular erythema, and an eschar on his lower leg. Laboratory findings revealed severe renal and liver dysfunction, disseminated intravascular coagulation (DIC), and markedly elevated soluble interleukin 2-receptor (sIL2-R) level (>10 000 U/ml). Administration of minocycline was started immediately, with a diagnosis of rickettsial infection. Simultaneously, anti-thrombin III and heparin were started to treat the DIC, and hemodialysis was also initiated. However, the day after admission, his consciousness level lapsed, to the level of coma, and blood pressure was less than 60 mmHg, indicating shock. Therefore, 500 mg of methylprednisolone was administered once; as a result, rapid pyretolysis and improvement of consciousness disturbance were achieved. Laboratory data indicative of inflammation gradually improved after a few days. Hemodialysis was required ten times. During the recovery period, the level of specific IgM antibody against Rickettsia japonica increased to ×2560, and he was diagnosed as having Japanese spotted fever. On July 11, he was discharged without sequelae. The course in our patient was very severe, and treatment with minocycline alone may have resulted in a fatal outcome. The level of sIL2-R, which is produced by activated lymphocytes, was markedly increased. Therefore, markedly elevated lymphocyte activation and hypercytokinemia may have been present on admission. The short-term steroid therapy may have been effective in inhibiting the excessive activation of lymphocytes in the critical stage. In the severe form of Japanese spotted fever with organ failure, combination therapy with minocycline and short-term steroids may be very useful. Received: May 10, 2001 / Accepted: July 6, 2001
