To quantify the enhancing activity of Freund's complete adjuvant (FCA), the humoral immune response of hens to the antigen human serum albumin (HSA) injected intramuscularly combined with FCA was measured. Local tissue reaction was examined on macroscopic and microscopic level. Other hens were injected with HSA in physiological sodium-chloride solution and served as controls. The immunization of hens without using FCA resulted in a short-term rise in immunoglobulin G (IgG) antibody titres, while the hens injected with HSA and FCA developed a long-term response (plateau-form of antibody titres). Local tissue reaction after injection of HSA in sodium-chloride solution was a mild and transient form of interstitial myositis. The immunization with HSA combined with FCA regularly resulted in a persisting granulomatous myositis. It is therefore a matter of animal protection to demand restricted use of FCA and to promote adjuvants of comparable efficiency, but better tolerance.

A 2-year-old boy developed acute myositis associated with rotavirus gastroenteritis. He had remarkable swelling and subcutaneous edema, mostly in the legs, 4 days after the onset of gastroenteritis. Marked elevation of creatine kinase was observed while serum albumin, immunoglobulin, and complement were decreased.

We report an infant case of rotavirus myositis, a rare complication of rotavirus infection. Complement levels of the patient were normal when serum creatine kinase (CK) level was at its peak and then decreased when the CK level became normalized. In a previous case report of rotavirus myositis, transient decrease of serum albumin, immunoglobulin, and complement levels was reported. The authors speculated that intravascular complement activation was caused by rotavirus and resulted in the pathogenesis of myositis, although complement levels at onset were not measured by the authors. In this report, however, we demonstrate that the complement activation of our patient is a result of, rather than the cause of, skeletal muscle damage.

Murine typhus occurs relatively commonly in southern Texas, as well as in California. We reviewed records of 90 adults and children in whom murine typhus was diagnosed during a 3-year period in 2 hospitals in southern Texas, USA. Most patients lacked notable comorbidities; all were immunocompetent. Initial signs and symptoms included fever (99%), malaise (82%), headache (77%), fatigue (70%), myalgias (68%), and rash (39%). Complications, often severe, in 28% of patients included bronchiolitis, pneumonia, meningitis, septic shock, cholecystitis, pancreatitis, myositis, and rhabdomyolysis; the last 3 are previously unreported in murine typhus. Low serum albumin and elevated procalcitonin, consistent with bacterial sepsis, were observed in >70% of cases. Rash was more common in children; thrombocytopenia, hyponatremia, elevated hepatic transaminases, and complications were more frequent in adults. Murine typhus should be considered as a diagnostic possibility in cases of acute febrile illness in southern and even in more northern US states.
