The study aimed to examine some laboratory changes in alcoholism patients suffering from community acquired pneumonia. Retrospective descriptive study included 36 alcoholism patients with community pneumonia diagnosed alcohol dependence according to ICD. 10 and diagnosed community acquired pneumonia. The results showed that all patients were male, mean age was 9.2 +/- 48.3, average alcoholism duration was 13.6 +/- 6.2 years, daily alcohol consumption less than 1L/day. Patients had mild anemia, medium MCV was 98 +/- 8. 1. 39 percent of patients had platelet decrease 50 G/I, the mortality rate among severely thrombocytopenia was higher than that in other groups (p 0.01). The percentage of patients with changes in SGOT and SGPT enzymes was 91.6 percent and 54 percent, respectively. 100 percent of patients had increased GGT, average GGT level was 386 +/- 34.4. 84 percent of the patients had increased blood creatinine 120 umol/L, 58 percent of patients with hyponatremia. The average serum potassium was 3.8 +/- 0.6 mmol/L, 6/36 patients had K+ 3.5 mmol/L and 3/36 patients had K + 4,5 mmol/L. Some laboratory characteristics related to increased mortality as malnutrition, severe thrombocytopenia, electrolyte disorders should have early intervention strategy for patients with alcoholism community pneumonia.
