Course of acute traumatic uveitis was evaluated in 146 patients with penetrating wounds of different severity in scores starting from the first days after the injury was inflicted and after operations performed in early terms after the injury. The inflammatory process normalized by weeks 2-3 in a favorable course, while in severe injuries and early reoperations and in wounds of the fourth degree of severity posttraumatic uveitis persisted during weeks 3-4, and 35.2% patients developed chronic posttraumatic uveitis. Clinical signs of immunological insufficiency, presenting mainly as the infectious syndrome (28%), were detected in 35.6% patients with penetrating injuries on the basis of case history analysis by means of a universal diagnostic chart and clinical findings. Penetrating wounds of the third and fourth degree of severity, reoperations during early terms after primary surgical treatment, chronic inflammatory diseases (mainly of the ENT and bronchopulmonary system, indicating secondary immunodeficiency, which necessitate prescription of immunocorrectors starting from the first days after the injury) are factors of risk of protracted or chronic course of posttraumatic uveitis.

Nonspecific and specific immunity values were studied in 70 children before and in various periods after 74 operations on the anterior segment of the eyeball. In children with persistent autosensitization to ocular tissue autoantigens (alpha-crystalline and S-antigen) postoperative uveitis presented as an immunocomplex disease with signs of exhaustion of the functional potential of the phagocytosis and complement systems. In children without autosensitization uveitis was associated with immunity activation. Phagocytosis system and cooperation of lymphocyte subpopulations, including normal killers (CD16+), play an important role in prevention of sensitization to ocular tissue autoantigens. Therefore, complex immunological examinations of children before surgery and regular check-ups after it will help differentiate immunodeficiency from compensatory immunosuppression preventing autoimmune disease, which is important in prescription of immunostimulating therapy.

Therapeutic and prophylactic regimens directed specifically against Mycobacterium avium complex (MAC) are increasingly being used in patients infected with the human immunodeficiency virus (HIV). Several of the drugs used in the management of MAC have been associated with significant drug interactions involving the cytochrome P450 (CYP) enzyme system. This enzyme system is also highly influenced by other drugs used in the management of patients with HIV, particularly the protease inhibitors, non-nucleoside reverse transcriptase inhibitors (NNRTIs) and azole antifungals. This article reviews the published concentrations or subtherapeutic concentrations of other drugs have been described. In particular, concurrent use of rifabutin with clarithromycin or fluconazole has resulted in increased concentrations of rifabutin and an accompanying increase in the incidence of rifabutin toxicities, including uveitis and leucopenia. Similar results have been seen when rifabutin is combined with protease inhibitors or delavirdine. The macrolides, clarithromycin and azithromycin, have also been associated with significant drug interactions. Clarithromycin has a higher affinity for CYP than azithromycin and, thus, is more frequently associated with clinically significant drug interactions. Clarithromycin is an inhibitor of CYP and may result in toxic concentrations of other drugs metabolised by this enzyme system. Such interactions have been described with rifabutin and the statin lipid-lowering agents. In addition, nevirapine and efavirenz have been shown to significantly reduce clarithromycin concentrations, whereas the protease inhibitors and delavirdine may increase clarithromycin concentrations. Other drugs used in the management of patients with MAC are not metabolised by CYP and thus have a lower incidence of interactions, although the absorption of ciprofloxacin may be impaired when it is given with products containing multivalent cations, such as didanosine. However, clinicians must remain vigilant for drug interactions when reviewing a patient's medication profile, keeping in mind both interactions that have been described in the literature and those that may be predicted based upon known pharmacokinetic profiles.

Clinical course of wound process in the eye was studied in 279 patients with penetrating wounds of different severity. Modern microsurgical and drug treatment of penetrating wounds results in a favorable course in 2/3 (77.4%) of patients, while in the rest 22.6% the course of healing was complicated by intraocular infection (10.7%) and chronic noninfectious posttraumatic uveitis (11.7%). Risk factors of a complicated course were defined, among which of special importance are specific features of the injury and secondary immunodeficiency, clinically manifesting by chronic inflammatory diseases, predominantly of the ENT organs and bronchopulmonary system.

Variability of clinical manifestations of rheumatoid uveitis, possibility of an atypical course (peripheral or panuveitis), and greater severity and specific features of the disease in case of its early (before the age of 3 years) manifestation are demonstrated on the basis of observations of 79 patients with rheumatoid uveitis. Despite systemic therapy with corticosteroids and cytostatics, no manifest post-steroid immunodeficiency was observed. Moderately expressed gammapathies were detected in 60% cases; hypoimmune states predominated, which were more often detected in children aged under 6 years. No cases of pronounced suppression of functional activity of lymphocytes were observed. Humoral and cellular response to persistent ophthalmotropic infections were observed more rarely than in children with uveitis of other etiology. Positive rheumatoid factor was detected in 9% cases, antinuclear antibodies in 60%. Antibodies to DNA were detected in the sera of 10% examinees, to native and denatured DNA in the lacrimal fluid of 21.2 and 16.7%, respectively. The causes of absence of obvious post-steroid immunodeficiency and relatively low rate of interorgan autosensitization in children with juvenile rheumatoid arthritis and uveitis are discussed. Further investigation of clinical and immunological correlations are needed for improving the prediction of the course of rheumatoid uveitis and development of treatment strategy.

Ocular tuberculosis is relatively rare; however, the most common ocular lesion during ocular tuberculosis is uveitis. The recrudescence of this disease is probably caused by human immunodeficiency virus or long-term corticotherapy. The authors report a of chronic unilateral tuberculosis-related uveitis complicated by panophthalmia with subconjunctival abcesess and scleral fistula. A histopathological study revealed a granulomatous inflammation with caseous material. An extensive work-up revealed no extraocular lesion. A systemic bactericidal treatement associated with topical steroids decreased the local inflammation with phthisis bulbi, and with no spread of the infection. The authors discuss the etiopathogenic, clinical, and therapeutic aspects of tuberculosis-related uveitis.

Twenty-one patients with syphilitic posterior uveitis were investigated retrospectively to study the disease spectrum, associations with neurosyphilis, and therapeutic implications. Ophthalmologic manifestations of syphilitic posterior uveitis are differentiated into acute and chronic uveitides. The several distinct acute uveitic syndromes are usually florid and are associated with early syphilis, with VDRL-positive syphilitic meningitis, and frequently with human immunodeficiency virus coinfection. The chronic posterior uveitides are often insidious, a manifestation of late syphilis, and associated commonly with subclinical neurosyphilis. All patients with acute cases and 54% of patients with chronic cases in our study received penicillin therapy appropriate for neurosyphilis. The frequent association of syphilitic posterior uveitis with neurosyphilis and the analogous spirochetal sequestration beyond the blood-brain and the blood-ocular barriers suggest that all patients with syphilitic posterior uveitis, irrespective of ocular disease intensity, should undergo evaluation of cerebrospinal fluid and be treated with penicillin regimens appropriate for neurosyphilis.

In females and males with uveitis, a similar picture was to be seen of changes in indices for the titre of antibodies in the peripheral blood. It could be summarized that a more profound immunodeficiency in those specimens demonstrating elevated parameters for acetylation is associated with a stronger impact of products of the inflammatory reaction in the eye to immunocompetent cells. But more in-depth research is needed into this question to resolve it.

Sixteen human immunodeficiency virus (HIV)-infected patients with inactive cytomegalovirus (CMV) retinitis who had discontinued systemic anti-CMV therapy while receiving highly active antiretroviral therapy (HAART) were prospectively observed. Fifteen patients developed immune recovery uveitis (IRU); 3 of the patients developed extensive retinal neovascularization, 1 of whom required vitrectomy for recurrent vitreous hemorrhages. These late complications indicate a need for continued ophthalmologic follow-up of HIV-infected patients who have a history of CMV retinitis, even for individuals who have not required anti-CMV therapy for >4 years.

Infection with human T-cell lymphotrophic virus-I (HTLV-I) is now a global epidemic, affecting 10 to 20 million people. This virus has been linked to life-threatening, incurable diseases, adult T-cell leukemia/lymphoma (ATLL), and HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP), as well as several chronic illnesses, such as uveitis and dermatitis. The cumulative lifetime risk of developing these incurable diseases is approximately 5% in asymptomatic patients. For operating room personnel performing surgery among patients from high-risk groups, HTLV-I and its associated diseases are presenting an increasing challenge. This report describes its transmission, seroprevalence, treatment, and public health initiatives that must be instituted to prevent the spread of this retrovirus. Coinfection with HTLV-I and human immunodeficiency virus (HIV) has been shown to accelerate the progression of acquired immune deficiency syndrome (AIDS).
