[Cycloferon administration in chronic pyelonephritis: changes in interferon status]
Aim:
To detect correlations between changes in interferon (INF) system and a course of chronic pyelonephritis (CP), to ascertain a corrective effect of cyclopheron in combined treatment with antibacterial drugs.
Material And Methods:
We examined 30 CP patients in different periods of the disease: group 1 had latent CP without laboratory evidence for exacerbation, group 2 had CP exacerbation treated with antibiotics, group 3 had exacerbation given basic treatment and cyclopheron by a standard scheme. All the patients were examined for interferon status, patients of groups 2 and 3 were examined once more after therapy.
Results:
Patients of all the groups showed diminished ability of blood leukocytes to produce IFN, especially IFN-gamma. Cyclopheron addition to antibacterial therapy significantly stimulated production of IFN alpha and gamma by blood cells compared to basic therapy. Examination of 5 patients after 1-year follow-up detected preserved ability of blood cells to produce IFN and reduce the number of exacerbations after combined treatment with cyclopheron.
Conclusion:
Administration of cyclopheron in combination with standard antibacterial treatment results in persistent correction of IFN status.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
