Familial cold autoinflammatory syndrome with rheumatoid arthritis.

Familial cold autoinflammatory syndrome (FCAS) is a cryopyrin-associated periodic syndrome that presents with episodic fever, skin rash, and joint pain after exposure to cold temperatures. Although the diagnosis is often singular, there are several instances of concurrent underlying autoimmune pathologies with either rheumatoid arthritis (RA) or amyloidosis. Because symptoms of the two entities overlap, it can be difficult to address a potential dual diagnosis of FCAS and an autoimmune disorder.

Treatment of Kounis syndrome.

Kounis syndrome is potentially a life-threatening medical emergency with both a severe allergic reaction and acute coronary syndrome. Most of the information about this syndrome has come from the case reports. The management of these patients may be challenging for clinicians, and unfortunately guidelines have not been established yet.

Derivation and validation of murine histologic alterations resembling asthma, with two proposed histologic grade parameters.

Background: The objective was to define murine histologic alterations resembling asthma in a BALB/c OVA model and to suggest grading criteria. Identified were six salient histologic findings in lungs with putative allergic inflammation: 1) bronchoarterial space inflammation; 2) peri-venular inflammation; 3) inflammation about amuscular blood vessels; 4) inter-alveolar space inflammation, not about capillaries; 5) pleural inflammation; and 6) eosinophils within the inflammatory aggregates. An initial study comprised six groups of twelve mice each: 1) stressed, control; 2) stressed, sensitized; 3) stressed, challenged; 4) not physically stressed, control; 5) not physically stressed, sensitized; 6) not physically stressed, challenged.

Cytokine expression in peripheral blood lymphocytes before and after aspirin desensitization in aspirin-exacerbated respiratory disease.

Aspirin intolerance is the hallmark of aspirin-exacerbated respiratory disease (AERD). Overproduction of cysteinyl-leukotrienes (Cys-LTs) has been implicated as major mediators of AERD; however, the LT receptor antagonist montelukast is only partially effective in inhibiting aspirin responses. Several studies have documented the importance of cytokine production by T lymphocytes in asthma.

Exhaled nitric oxide in asthma: variability, relation to asthma severity, and peripheral blood lymphocyte cytokine expression.

Exhaled nitric oxide has been used as a means of indirectly measuring the underlying inflammation in asthma. The objectives of the study were to measure exhaled nitric oxide levels in asthma patients and healthy volunteers, to study peripheral blood lymphocyte cytokine expression, and to study the relationship between exhaled nitric oxide and intracellular cytokine expression. Exhaled nitric oxide was elevated in patients with moderate to severe asthma and with treatment decreased in the first week reaching to a near normal level by 4 weeks.
