Meta-analysis of the controlled trials of garlic to reduce hypercholesterolemia showed a significant reduction in total cholesterol levels. The best available evidence suggests that garlic, in an amount approximating one half to one clove per day, decreased total serum cholesterol levels by about 9% in the groups of patients studied.

ACE inhibition initiated prior to severe renal insufficiency may offer long-term renal survival benefits in HIVAN. Diagnosis should be sought early in patients with clinical signs suggestive of HIVAN.

Using a commercially available immunoblot test kit, the presence of any 2 IgM bands is proposed as a positive result. The predictive value of a positive IgM immunoblot result, however, is poor in patients with minimal clinical evidence for Lyme disease.

We showed for the first time in Central European Slovak population that MS onset age is an early marker that is in the positive correlation with disease disability progression rate, evaluated by MSSS score. We conclude that relapsing-remitting MS patients older at clinical onset have a higher risk of unfavorable prognosis (Tab. 2, Fig. 1, Ref. 21).

To improve the accuracy of testing for antibody to Borrelia burgdorferi, 2-stage conditional testing has been recommended, in which sera that yield positive or equivocal results in a first-stage test (e.g., an ELISA) are then tested by immunoblot assay. The increased specificity anticipated with sequential testing, however, depends on immunoblot assays and ELISAs being independent tests. To examine whether they are independent, control serum samples were tested with 2 different commercially available IgM ELISAs and with an IgM immunoblot assay kit. The frequency of false-positive IgM immunoblot assays was significantly higher with ELISA-reactive than with ELISA-negative serum samples (P
