An easy-to-perform immunologic test for histoplasmosis is described. The test, involving precipitin reactions in agar gel, appears to have greater sensitivity and specificity than currently available tests for histoplasmosis. It is useful in the study of small or large numbers of patients. It has been possible to demonstrate at least one antigen common to H. capsulatum, B. dermatitidis, and C. immitis. This antigen may be responsible for cross reactions. Instances are cited wherein problems of cross reactions and false-positive reactions have been clarified by means of precipitin-in-gel studies. Precipitin reactions in agar have provided presumptive diagnosis of histoplasmosis in a patient with acute pericarditis, which rapidly progressed to constrictive pericarditis necessitating pericardiectomy.

Abstract In recent years it has been well documented that the characteristic increase in plasma lipoproteins in patients with obstructive jaundice is the result of the presence of a low-density lipoprotein (relative density 1.006-1.063 g/ml) of abnormal composition and properties. This abnormal lipoprotein has been designated "LP-X." The development of a simple immunologic test system for determining LP-X provides the basis for a new clinical chemical test that is of use in the differential diagnosis of jaundice. In this study, 2680 LP-X determinations were performed on 1481 subjects: 1309 patients with or without liver disease, and 172 healthy volunteers. Statistical analysis of this series revealed a power of 0.99 and a specifity of 0.98 to demonstrate or exclude cholestasis. In this regard the new test is superior to other blood-chemical assessments. It was never positive in patients without liver disease. However, the LP-X test alone is not adequate to distinguish between intrahepatic cholestasis and extrahepatic biliary obstruction

OBJECTIVES: This study aimed to systematically review and quantitatively synthesize the association between HLA-B*5701 and abacavir-induced hypersensitivity reaction (ABC-HSR). METHODS: We searched for studies that investigated the association between HLA-B genotype and ABC-HSR and provided information about the frequency of carriers of HLA-B genotypes among cases and controls. We then performed a meta-analysis with a random-effects model to pool the data and to investigate the sources of heterogeneity. RESULTS: From 1,026 articles identified, ten studies were included. Five using clinical manifestation as their diagnostic criteria, 409 and 1,883 subjects were included as cases and controls. Overall OR was 23.6 (95% CI = 15.4 – 36.3). Whereas, the another five studies using confirmed immunologic test as their diagnostic criteria, 110 and 1,968 subjects were included as cases and controls, respectively. The association of ABC-HSR was strong in this populations with HLA-B*5701. Overall OR was 1,056.2 (95% CI = 345.0 – 3,233.3). CONCLUSIONS: Using meta-analysis technique, the association between HLA-B*5701 and ABC-HSR is strong in the studies using immunologic confirmation to identify ABC-HSR. These results support the US FDA recommendations for screening HLA-B*5701 allele before initiating abacavir therapy.This article is open to POST-PUBLICATION REVIEW.

Sjögren's Syndrome (SS) is a chronic, multisystem. autoimmune disorder. It is characterized by (1) generalized exocrine gland dysfunction, (2) serologic abnormalities, and (3) organ-system changes. Oral changes are a prominent feature of this disease. Among these are xerostomia and hypofunction of the salivary glands. Given the intimate relationship between SS and the salivary glands, it is reasonable to postulate that whole saliva (WS) contains the stigmata associated with the presence of this disease. But few studies have been conducted on this secretion. Indeed, WS has largely been neglected and ignored by physicians, dentists, and scientists. Objections to its use have included the fact that it is "impure", that it does not adequately represent what is present in the salivary glands, that no standards have been established for its rate of flow, and that findings based on it lack specificity. Yet, it is this secretion which coats and protects the hard and soft oral tissues, enables us to prepare our food for digestion, and assists our speech. This review will demonstrate that there is a uniqueness and constancy to whole saliva and that it may be used to diagnose the presence of SS. "Screening tests", which include several simple-to-perform sialometric, chemical, and microbiologic procedures, may be conducted in doctors' offices to establish the "profile" of an SS patient. Electrophoretic studies may be used to study the nature of the salivary proteins, and an immunologic test, which is performed on WS and utilizes Western Blot Autoantibody Strips (ImmunoVision. Springdale, AR). may be used to establish the definitive diagnosis of SS.

Numbers and percentages of T and B cells in peripheral blood; blastogenic responses to PHA, Con A, and PWM; and serum levels of albumin, total protein, and IgA were assessed in patients with stages I to III operable squamous cell carcinoma of the upper aerodigestive passageways in the head and neck. The patients were categorized into two groups: those who remained tumor free and those in whom cancer recurred. It was found that pretreatment PHA- and Con A-induced blastogenesis was often depressed in patients in whom clinically apparent recurrences developed regardless of stage or nodal involvement. This point is consistent with the idea that cellular immune function (blastogenesis) can identify, within the clinical staging system (TN), subpopulations of patients who are less likely to survive after conventional therapy.
