    The urinary uroporphyrin and 7-carboxylated porphyrin levels were markedly elevated along with smaller elevations of 5- and 6-carboxylated porphyrins. The fecal coproporphyrins and isocoproporphyrins were also elevated Table II. The porphyrin profiles of immediate family members could not be assessed because of lack of consent. Oct 30, 2019 Hydroxychloroquine can be detected in the cord blood at delivery in concentrations similar to those in the maternal serum Costedoat-Chalumeau 2002. In animal reproduction studies with chloroquine, accumulation in fetal ocular tissues was observed and remained for several months following drug elimination from the rest of the body. Anuric individuals can be readily diagnosed by assaying a plasma or serum specimen for the characteristic elevated levels of polycarboxylated porphyrins. Quantitative plasma porphyrin levels are often much higher than those of patients with normal renal function, who excrete large amounts of these water-soluble porphyrins in urine.

Infection with dengue virus DENV is a global public health problem, and we lack an antiviral drug for DENV.
