The increase of tuberculosis incidence in last decade stimulated elaboration of both new antituberculous drugs and also searches ofoptimiting delivery systems for existing drugs. It is determined by their side effects and low bioavailability of effective first line drug rifampicin. Various nanosystems for transport of antituberculous drugs are considered on the basis of various polymers, liposomes, lipid nanoparticles, nanoemulsios, nanosuspensions, dendrimers, cyclodextrines. Influence of drug incorporation into nanoparticles, most often for rifampicin, on pharmacokinetics and efficiency in tuberculosis models is discussed. The most of works are devoted to polymer nanoparticles for oral administration where increased circulation time and efficiency were shown. The best results were observed after drug inclusion into solid lipid nanoparticles. The liposomes formulations were investigated mostly for inhalation and injection administrations. Positive results were also observed. Authors underline the viability of incorporation of antituberculous drugs into phospholipid nanoparticles that may increase intestinal absorption and bioavailability. It is confirmed by authors' own data that showed increase of rifampicin efficiency after their incorporation into such nanoparticles.

Most of the drugs that we use in our everyday clinic cause ocular side effects or toxicity, depending on the drug duration and dose. Eye care physicians should be familiar with any possible ocular side effects linked to these medications, which could save the physicians' time to determine the diagnosis of the ocular irritation or toxicity. Not all medications are listed in this review, but we did go over the most common systemic medications based on our experience seeing patients in our everyday clinic.

This comparative study aimed at qualifying a broth microdilution (BMD) assay for phenotypic drug susceptibility testing (pDST) of complex (MTBC) strains for implementation in a routine DST workflow. The assay was developed based on the EUCAST (European Committee on Antimicrobial Susceptibility Testing) reference protocol for determination of the minimum inhibitory concentration (MIC) of 14 anti-tuberculous drugs (isoniazid [INH], rifampicin [RIF], ethambutol [EMB], amikacin [AMI], moxifloxacin [MFX], levofloxacin [LFX], bedaquiline [BDQ], clofazimine [CFZ], delamanid [DLM], pretomanid [PA], para-aminosalicylic acid [PAS], linezolid [LZD], ethionamide [ETH], and cycloserine [CS]). Forty MTBC strains with various drug resistance profiles were tested to determine the agreement between MIC results and genotypic drug susceptibility testing (gDST) results derived from whole-genome sequencing (WGS).

Tuberculosis (TB) is an infectious disease caused by (MTB). Disseminated TB can cause various types of complications. Extrapulmonary TB includes TB meningitis, abdominal TB, skeletal TB, Pott's disease (spine), scrofula, and genitourinary TB.

Objectives: Cutaneous tuberculosis (CTB) may be over-diagnosed due to imprecise diagnostic criteria or overlooked where mycobacterial investigations are negative. We evaluated the distinction between multibacillary and paucibacillary forms of CTB, as well as drug resistance and cure rates according to the results of mycobacterial investigations.
Methods: We included retrospectively all patients diagnosed with CTB from 1995 to 2018 in two hospitals in Paris.

Tuberculosis (TB) continues to be a major global health burden, with high incidence and mortality rates, compounded by the emergence and spread of drug-resistant strains. The limitations of current TB medications and the urgent need for new drugs targeting drug-resistant strains, particularly multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB, underscore the pressing demand for innovative anti-TB drugs that can shorten treatment duration. This has led to a focus on targeting energy metabolism of Mycobacterium tuberculosis (Mtb) as a promising approach for drug discovery.
