[Comparative clinical and immunological parameters in convalescence of patients with icterohemorrhagic leptospirosis].

AIM: To investigate clinico-immunological parallels of convalescent period in leptospiral jaundice (LJ). MATERIAL AND METHODS: Clinical and immunological indices were studied in 121 LJ convalescents (97.6% males, age 17-45 years). RESULTS: Acute leptospirosis period was characterized with polymorphic clinical picture impeding precise diagnosis and threatening with such complications as bacterial shock, acute renal failure, acute renal-hepatic failure, DIC-syndrome, respiratory distress. Convalescents for a long time exhibited polyorganic pathology, developed sepsis. In late convalescence one could observe affections of the heart, liver, kidneys, bones, nervous system, eyes. This can be explained by disorders in immunity, especially structural immunodeficiency, and commissures at the sites of hemorrhages. CONCLUSION: Polyorganic pathology in leptospirosis convalescents arises because of immunity disorders which are not associated with the disease form. In late convalescence severe complications may accompany leptospiral jaundice.

[Hepatobiliary alternations in leptospirosis convalescents].

AIM: To study hepatic function in leptospirosis convalescents. MATERIALS AND METHODS: Clinical laboratory and device examinations were performed in 121 leptospirosis convalescents. RESULTS: The majority of the examinees retained biochemical signs of cholestatic, mesenchymal-inflammatory and moderate cytolytic syndromes secondary to hepatic impairment. Ultrasound and radionuclide investigations detected biliary disorders and secondary chronic hepatitis in many of leptospirosis convalescents. CONCLUSION: It is shown that leptospirosis rehabilitation must be targeted. Reasons of development of chronic hepatic and biliary lesions in population of the north Caucus and Kuban in the absence of viral hepatitis markers are suggested.

[Renal involvement in convalescents after icterohemorrhagic leptospirosis].

Icterohemorrhagic spirochetosis convalescents develop slowly regressing renal dysfunctions most frequent of which are chronic renal failure, pyelonephritis and tubulointersticial nephritis, arterial hypertension. Renal disorders may be due to immunopathological reactions followed by activation of bacterial microflora. Damage from commissures at the sites of prior hemorrhage is also possible. In bovine leptospirosis renal damage is not so severe but it tends to progression. So, renal affection in leptospirosis is a specific pathology observed in any clinical form of the disease and demands surveillance in the regions of local focuses.

[Cardiovascular function in leptospirosis convalescents].

AIM: To study mechanisms of cardiovascular damage in leprospirosis convalescents. MATERIALS AND METHODS: Cardiovascular system was investigated in 121 leptospirosis convalescents at the age 17-58 years clinically, electrocardiographically and measuring troponin-T in blood serum. RESULTS: 6-12 months after leptospirosis 42.1% of patients who had leptospiral jaundice (88.4%) and bovine leptospirosis (21.6%) myocardial damages were revealed. In spite of disappearance of cardiac pain ECG readings did not return to normal. The myocardial damage has developed in the advanced stage of leptospirosis due to rhandomyolis: high concentration of myoglobin and troponin-T in the blood serum confirms this suggestion. CONCLUSION: Clinical ECG readings as well as the level of troponin-T in the blood serum may be considered as the index of rehabilitation level in leptospirosis convalescents. It should be taken into consideration that 19.8% of the convalescents develop hypertension of renal genesis. This should be accounted for when planning prophylaxis and rehabilitation programs for young patients living in the North Caucasus--natural source of leptospirosis.

[Clinical features and cellular immunity in patients with icterohemorrhagic leptospirosis].

Time course of cellular immunity parameters was followed up in 56 patients with different forms of icterohemorrhagic leptospirosis of various severity. A grave course of the disease was associated with development of secondary structural immunodeficiency manifesting by reduction of E = RFC count, of immunoregulatory index, and of the count of T lymphocytes. The course of convalescence was found related to the immune response: if immunodeficiency persisted during the early convalescence period, the patients developed late complications.
