Doxycycline and changes in weight.
We observed that 11/48 (23%) treated patients showed abnormal weight gain (+2 to +13 kg, corresponding to +4% to +18% ΔBMI), and this proportion was significantly different from that in the controls (0/34 [0% according to our definition]; P = 0.001, two-sided Barnard's test) (Fig.
It is effective against bacteria such as Moraxella catarrhalis, Brucella melitensis, Chlamydia pneumoniae, and Mycoplasma pneumoniae. Additionally, doxycycline is used in the prevention and treatment of serious conditions like anthrax, leptospirosis, bubonic plague, and Lyme disease.
Clarithromycin is an antibiotic. It's used to treat chest infections such as pneumonia, skin problems such as cellulitis, and ear infections. It's also used to treat Helicobacter pylori, a bacteria that can cause stomach ulcers.
RESULTS: Duration of frequent daytime cough after entry was a mean of 1.5 days shorter in the group of 71 patients receiving doxycycline than in the group of 69 patients on placebo (4.7 days versus 6.2 days, respectively).
Background Doxycycline has a high degree of activity against many common respiratory pathogens and has been used in the outpatient management of lower respiratory tract infections, including pneumonia.
