Drug interactions are a frequent and clinically important cause of poor blood pressure control, adverse effects of antihypertensive treatment and worsening kidney function. In general practice, it is important to consider not only interactions among antihypertensive agents themselves, but also commonly used prescription and over-the-counter drugs that may increase blood pressure or reduce treatment efficacy. The most relevant examples include non-steroidal anti-inflammatory drugs, nasal decongestants with sympathomimetic activity, selected antidepressants, glucocorticoids and hormonal therapy. Particularly important are combinations of renin-angiotensin...

The HIV pandemic has lasted for more than four decades. However, a significant number of people continue to become newly infected. Antiretroviral therapy (ART) can ensure a good quality of life and is also used as prevention. After a certain period of use, ART leads to an undetectable viral load and effectively prevents the transmission of HIV to other people. For this reason, since 2015 it has been initiated in all individuals as soon as possible after an HIV diagnosis is established. Due to the increasing number of newly diagnosed HIV-positive clients with reduced immunity at the HIV Centre in Ostrava, we decided to analyse the percentage of individuals...

Acute mesenteric ischaemia (AMI) is a serious clinical condition with overall short-term mortality exceeding 50-60 %. Although the incidence of the acute form surpasses 60/100 000 inhabitants per year in the population of patients over 70, the diagnosis is still established with an alarming frequency of delay or only at autopsy. The key prerequisite for patient survival is not so much the availability of modern treatment as active clinical suspicion on the part of the first-contact physician. This review summarises the pathophysiology, aetiological classification, diagnostic algorithm and therapeutic options for both forms of ischaemia - acute and...

Perimenopause and menopause represent key phases of reproductive aging in women, triggering endocrine, metabolic and cellular changes. Traditionally, they have been perceived primarily as hormonally conditioned processes with the occurrence of vasomotor symptoms. Current findings show that menopause reflects a broader biological aging process involving molecular and systemic alterations. The associated hormonal imbalance contributes to bone loss, central fat accumulation, changes in the urogenital, immune and nervous systems with an increased cardiovascular risk. The menopausal period also predisposes women to type 2 diabetes and metabolic syndrome....

Gastroesophageal reflux disease (GERD) is one of the most common diseases encountered by both primary care physicians and gastroenterologists in their specialized outpatient clinics. Reflux symptoms such as heartburn, regurgitation, or chest pain may indicate not only true reflux disease, but also extra-esophageal diseases, including disorders of impaired autonomic nervous system balance. The management of patients with reflux symptoms has changed significantly in recent years, mainly due to the increased use of diagnostic methods such as 24-hour pH metry with impedance, wireless esophageal pH metry, and high-resolution esophageal manometry. These...

Vitamin D has traditionally been associated with skeletal health; however, current knowledge indicates that its biological role extends beyond calcium-phosphate metabolism. The active form, 1,25(OH)₂D, acts through the vitamin D receptor expressed in numerous tissues and may be involved in the regulation of immune functions, inflammatory responses, cardiovascular homeostasis, cellular proliferation, and other extraskeletal processes. At the same time, vitamin D deficiency remains highly prevalent, especially in regions with limited seasonal cutaneous synthesis. The clinical relevance of vitamin D therefore lies not only in its pleiotropic biological...
