The clinical picture with, among other things, muscular swelling, fever and nocturnal sweating in three males aged 30, 37 and 52 years, suggested a neoplasm and sepsis. Ultimately, they were found to suffer from focal myositis, localized nodular myositis and polymyositis, respectively. The ESR and leukocyte counts were increased, the serum creatinine kinase (CK) activity was normal or slightly increased. The symptoms decreased after prednisone treatment. Both localized and generalized inflammatory muscular diseases may be present without the serum CK activity being raised.

The effect of an ethanol extract of Commiphora myrrha oleo-gum resin on hematological and pathophysiological parameters of male Wistar rats was examined. The extract was given daily for 2 w at 1000 mg/kg bw per os, 500 mg/kg bw i.m. or 250 mg/kg bw i.p. Depression, huddling together, soft feces, jaundice, ruffled hair, hepatonephropathy, hemorrhagic myositis and patchy peritonitis (at the injection site) and death were accompanied by increases in serum ALP and ALT activities, bilirubin, cholesterol and creatinine concentrations, and decreases in total protein and albumin levels, and macrocytic anemia and leucopenia. When administered at 500 mg extract/kg bw/d per os or 250 mg extract/kg bw/d i.m. for 2 w it was not lethal, and when given daily for 1 w the effect was less marked.

Seven members of a 15-man U.S. military team that had operated in rural Malaysia developed an acute illness consisting of fever, myalgias, bronchospasm, fleeting pruritic rashes, transient lymphadenopathy, and subcutaneous nodules associated with eosinophilia, elevated erythrocyte sedimentation rate, and elevated levels of muscle creatinine kinase. Sarcocysts of an unidentified Sarcocystis species were found in skeletal muscle biopsies of the index case. Albendazole ameliorated symptoms in the index case; however, his symptoms persisted for more than 5 years. Symptoms in 5 other men were mild to moderate and self-limited, and 1 team member with laboratory abnormalities was asymptomatic. Of 8 team members tested for antibody to Sarcocystis, 6 were positive; of 4 with the eosinophilic myositis syndrome who were tested, all were positive. We attribute this outbreak of eosinophilic myositis to accidental tissue parasitism by Sarcocystis.

Myositis associated with graft-versus-host-disease (GVHD) typically presents with proximal muscle weakness, myalgias, and a raised creatinine phosphokinase (CPK) level. We report a case of a 51 year old man who developed respiratory muscle weakness five years after an allogeneic bone marrow transplant for multiple myeloma. His symptoms included tachypnoea, abdominal paradox, and orthopnoea. Pulmonary function tests revealed diminished vital capacity and maximal inspiratory and expiratory pressures. Serum CPK levels were raised and a peripheral muscle biopsy specimen was consistent with GVHD. He improved with immunosuppressive therapy.

Eleven cases (5 F + 6 M; mean age 48.0 years) of acute noninflammatory renal failure (ANRF) in the course of rhabdomyolysis (RBM) were treated with hemodialysis in years 1995-1999. The causes of RBM were the following: ischemia of lower limbs after vascular operations (4 cases), exhausting exercise with rapid body cooling (3 cases), multiorgan failure after traffic accident, acute myositis (1 case), status epilepticus (1 case), rapid clinical course of viral infection (1 case). It was necessary to perform from 1 to 13 hemodialyses in every patient. In nine cases, complete normalization of renal function during 5 to 30 days of therapy was achieved. Two patients died due to multiorgan complications after vascular operations despite effective dialysis therapy. The following correlation were found: positive between initial values of creatine phosphokinase (CPK) activity and creatinine and uric acid concentrations in the blood and negative correlation between CPK and serum calcium concentrations. The higher initial values of CPK activity were observed the more hemodialysis procedures were necessary and the longer time was needed to normalize renal function. On the base of initial, limited up to now, own results it seems that hemodialysis in ANRF in the course of RBM should be started immediately in cases with high activity of CPK in the blood (above 10,000 U/L).

To investigate the pathogenesis of influenza myositis in animals, juvenile BALB/c mice were inoculated with influenza B/Lee virus intramuscularly into the right quadriceps muscle. Chicken normal allantoic fluid (NAF) or phosphate-buffered saline (PBS) was injected into the left quadriceps of control mice and in some virus-infected mice. Serum creatinine phosphokinase (CPK) levels rose significantly on days 1 and 2 post-inoculation (PI) in only virus-inoculated mice. On days 2 and 3 PI, right quadriceps muscles developed scattered foci of a predominantly mononuclear inflammation in the perimysial connective tissue often adjacent to degenerating or necrotic muscle fibers. Immunofluorescent staining with specific anti-influenza B virus antisera showed muscle fibers that contained specific staining in nuclei and adjacent cytoplasm. Skip areas of staining within muscle fibers suggested that not all muscle nuclei within an individual muscle fiber were infected. A continuous fall in infectious virus titer in the right quadriceps muscles suggested the initial virus inoculum became inactivated and progeny virions were not produced. Left quadriceps muscle never had muscle necrosis or endomysial inflammation, specific staining of viral antigen, virus isolation, or viral RNA detected by the reverse transcriptase polymerase chain reaction assay. These findings support the hypothesis that a non-permissive influenza viral infection can develop in murine skeletal muscle that can damage specific nuclear domains of muscle fibers producing muscle degeneration or necrosis. A similar type of muscle infection may develop in humans that occasionally develop focal myositis during influenza.

A 54-year-old woman developed polymyositis 6 months after allogeneic bone marrow transplantation (BMT) for acute myelogenous leukemia transformed from myelodysplasia. At the onset of myositis, the patient had oral dryness, and the histology of oral mucosa was compatible with chronic graft-versus-host disease (GVHD). Muscle biopsy revealed focal muscle necrosis with massive lymphocytic infiltration. She was diagnosed with polymyositis, and the dose of cyclosporine was increased. Three months later, a complete resolution of myositis had been obtained, and the cyclosporine was tapered off. However, 51 months after the first episode of myositis, she again noted severe myalgia and was diagnosed with a recurrence of polymyositis based on high serum creatinine kinase (CK) and the findings of magnetic resonance imaging (MRI). At that time, chronic GVHD in other organs was not present. She achieved a second remission of polymyositis with cyclosporine, and has remained in remission for 4 years. The pathogenesis of myositis can be attributed to the immunologic imbalance characteristic of the post-allogeneic BMT setting.

Fibric acid derivatives are a class of hypolipidaemic drugs used in the treatment of patients with hypertriglyceridaemia, mixed hyperlipidaemia and diabetic dyslipidaemia. Fibrate therapy results in a significant decrease in serum triglycerides and an increase in high-density lipoprotein (HDL) cholesterol levels. The latest drugs of this class are also effective in lowering low-density (LDL) cholesterol levels and can change the distribution of LDL towards higher and larger particles. The effects of fibrates on lipid metabolism are mostly mediated through the activation of peroxisome proliferator-activated receptors (PPARalpha). A number of angiographic and clinical trials have confirmed that fibrates can slow the progression of atherosclerotic disease and decrease cardiovascular morbidity and mortality. Recently published data suggest that the ability of fibrates to prevent atherosclerosis is not related only to their hypolipidaemic effects but also to other 'pleiotropic effects', such as their anti-inflammatory, antioxidant and antithrombotic effects, as well as their ability to improve endothelial function. Interestingly, fibrates may favourably influence the thrombotic/fibrinolytic system. In fact, most of these drugs can significantly decrease plasma fibrinogen levels and inhibit tissue factor expression and activity in human monocytes and macrophages. Some studies have shown that fibrates can improve carbohydrate metabolism in patients with dyslipidaemia, including diabetic patients. Among fibrates only fenofibrate can significantly decrease serum uric acid levels by increasing renal urate excretion. Fibrates, with the possible exception of gemfibrozil, can significantly increase serum creatinine and homocysteine levels. Finally, a reduction in serum alkaline phosphatase and gamma glutamyltranspeptidase (gammaGT) activity is a well-documented effect of therapy with fibrates. The fibrates are generally well-tolerated drugs with few side-effects. The most important side-effect is myositis, which is observed in patients with impaired renal function or when statins are given concomitantly.

A 47-year-old white woman with a history of stage III squamous cell carcinoma of the anus was transferred to Johns Hopkins Hospital for further evaluation of renal failure, hemolytic anemia, and thrombocytopenia. The patient was first diagnosed with squamous cell carcinoma of the anus 1 year before admission. She was treated with external beam radiation of the pelvis and two cycles of mitomycin C-based chemotherapy (a cumulative dose, 34 mg/m(2)). Her clinical course was complicated by Clostridium difficile colitis and myositis successfully treated with prednisone. Three months before admission, the patient developed dysuria. Her creatinine increased from normal to 1.7 mg/dL, and microscopic hematuria was present. A renal ultrasound and an abdominal computed tomographic scan showed no abnormalities or obstruction. One month before admission, she underwent a cystoscopy, which showed only radiation-induced changes in the bladder. Two weeks before admission, the patient became delirious and was taken to a hospital, where she was found to be anemic, with a hematocrit level of 23.7%, and thrombocytopenic with a platelet count of 110,000/mm(3). Her creatinine level was 5.9 mg/dL. Previous values of hematocrit, platelet count, and serum creatinine were normal. On admission at Johns Hopkins Hospital the patient had no complaints. She was afebrile on physical examination and had normal vital signs. Head, neck, chest, cardiovascular, and abdominal examinations were normal. There was skin pallor, but no echymoses or petechiae. She was alert and oriented with normal mental status. Her neurologic examination was normal. Laboratory data showed a white blood cell count of 6390/mm(3), a hematocrit level of 26.5%, and a platelet count of 26,000/mm(3). Her blood urea nitrogen level was 57 mg/dL, creatinine level was 4.0 mg/dL, and lactate dehydrogenase was 550 U/L (reference, 115 to 275 U/L). Urinalysis showed innumerable red blood cells and large protein. A peripheral blood smear showed fragmented red blood cells, schistocytes, no abnormal white blood cells, and few platelets. There was no radiographic or clinical evidence of relapse of her squamous cell carcinoma. What is the diagnosis?

Transient weakness of the legs developed in a 17 year-old male high school student three weeks after the initial injection of a hepatitis B vaccine. Seventeen days after the second injection of the vaccine, low-grade fever, a pruritic maculopapular rash appeared and weakness of the legs recurred. This was associated with elevation of the creatinine kinase to 2,406 U/L. The day after admission he became afebrile and in the subsequent four days the rash improved but leg weakness persisted. One-month later, muscle strength had returned; and the creatinine kinase had returned to normal levels. The only case of dermatomyositis associated with hepatitis B vaccination and the findings in the six reported cases of surface antigen-positive hepatitis associated with polyomyositis or dermatomyositis are briefly reviewed. Hepatitis B vaccination should be encouraged, but it is important to be aware that, rarely, dermatomyositis, polymyositis or neurovascular complications may occur. Polymyositis associated with the administration of the hepatitis B vaccine or with hepatitis B virus infection is a rare occurrence. A Medline Search performed from 1960 to January 2002 associating hepatitis B vaccine or hepatitis B virus with myopathy, myositis, polymyositis and dermatomyositis, showed only one case of dermatomyositis related to the hepatitis B vaccine, and six case reports relating polymyositis to hepatitis B virus infection. We present a case where a causal relationship between polymyositis and hepatitis B vaccination appears quite likely.
