An Exposure-Response Perspective on the Clinical Dose of Pretomanid.

Pretomanid was approved by the U.S. FDA, via the limited population pathway for antibacterial and antifungal drugs, as part of a three-drug regimen with bedaquiline and linezolid for the treatment of extensively drug-resistant and treatment-intolerant or nonresponsive multidrug-resistant tuberculosis.

Association between human leukocyte antigen class II alleles and genotype of Borrelia burgdorferi in patients with early lyme disease.

Background: On the basis of a polymerase chain reaction-restriction fragment-length polymorphism analysis of the 16S-23S ribosomal DNA intergenic spacer, clinical isolates of Borrelia burgdorferi can be classified into 3 genotypes designated as RST1, RST2, and RST3. RST1 strains are the most pathogenic, and RST3 strains are the least pathogenic.

Methods: Human leukocyte antigen (HLA) class II alleles were determined for a group of culture-positive patients with Lyme disease-associated erythema migrans and were evaluated for an association with the genotype of the infecting B.

A randomized study of the use of fluconazole in continuous versus episodic therapy in patients with advanced HIV infection and a history of oropharyngeal candidiasis: AIDS Clinical Trials Group Study 323/Mycoses Study Group Study 40.

Background: In human immunodeficiency virus (HIV)-infected patients, fluconazole prophylaxis is associated with reductions in the rate of fungal infection. However, concerns exist with regard to the use of fluconazole prophylaxis and the risk of development of fluconazole treatment-refractory infections.

Methods: We performed a randomized, open-label trial that compared oral fluconazole given continuously (200 mg 3 times weekly; the "continuous fluconazole arm") with fluconazole that was provided only for episodes of orophayngeal candidiasis (OPC) or esophageal candidiasis (EC) (the "episodic fluconazole arm") in HIV-infected persons with CD4+ T cell counts of <150 cells/mm3 and a history of OPC.

A case-control study to examine HLA haplotype associations in patients with posttreatment chronic Lyme disease.

In a comparison of 95 patients with systemic symptoms that persisted after antibiotic treatment for acute Lyme disease (posttreatment chronic Lyme disease) and 104 control subjects without such symptoms after antibiotic treatment, we sought associations between human leukocyte antigen class II (DRB1 and DQB1) markers and posttreatment chronic Lyme disease. No strong association between posttreatment chronic Lyme disease and any class II allele or genotype was found.

Relationship of peripheral arterial compliance and standard cardiovascular risk factors.

Abnormalities of peripheral arterial compliance are clinically useful markers of atherosclerosis and risk of vascular events. Local peripheral arterial compliance can be easily and accurately assessed in the clinic by computer-controlled pulse volume recordings (air plethysmography). The purpose of this study was to investigate the relationship between clinical cardiovascular risk factors, a surrogate of atherosclerotic burden, and peripheral arterial compliance in the thigh and calf determined by quantification of local pulse volume recordings in patients undergoing coronary angiography.
