ABSTRACT

Tuberculosis (Tb) is a chronic infectious disease in which the cellular immunity (specifically CD4+ and CD8 lymphocytes) provides the most important defense in controlling infection. CD4 lymphopenia is a well-defined risk factor for the development of active tuberculosis in patients infected with Human Immunodeficiency Virus. In HIV - negative patients, CD4 and CD8 cell count suppression has been associated with Tb infection. Our study was designed to determine the baseline and post-treatment values of CD4 and CD8 in HIV negative patients diagnosed with active Tb in Saudi Arabian patients. We recruited twenty-eight, non-HIV patients with tuberculosis for the study group comprising 16 males and 12 females with either disseminated or localized active Tb infection. Two control groups were selected one of twenty-one matched healthy controls and the second of forty-two subjects from pool of controls of an ongoing study in same population for normal CD4 and CD8 counts. The baseline pre-treatment CD4 and CD8 counts in the study group were significantly lower than either control group. Specifically the mean ± SD of CD4 counts were 556.79 ± 298.81 in the study group vs 1,132.38 ± 259.90 in control group 1 and 1,424.38 ± 870.98 in control group 2 (p 0.000). Likewise the CD8 counts in the study group were 1,136.00 ± 512.06 vs. 1,461.90 ± 367.02 in control group 1 and 1,495.90 ± 565.32 in control group 2 (p 0.000) respectively. After treatment of tuberculosis, the study patients experienced a significant increase in their mean ± SD CD4 and CD8 cell counts, from 556.79 ± 297.81 to 954.29 ± 210.90 for CD4 cells (p 0.005) and 1136.00 ± 512.06 to 1,316.54 ± 286.17 for CD8 cells (p 0.002). Analysis of study patients with disseminated disease found significantly lower CD4 cells (but not lower CD8 cells) compared to study patients with localized disease, both at baseline and after treatment. The mean ± SD baseline CD4 cells were 247.60 ± 187.80 with disseminated vs 728.56 ± 186.32 for localized disease (p = 0.000) which rose to 842.30 ± 93.55 vs 1016.50 ± 233.51 (p = 0.033) respectively. We conclude that tuberculosis may be associated with CD4 and CD8 lymphopenia even in patients without human immunodeficiency virus infection, there was the tendency of recovery towards normality especially of the CD4 and CD8 counts after treatment, and that disseminated disease is associated specifically with profound CD4 lymphopenia.

ABSTRACT

Tuberculous liver abscess is rare worldwide. We report a 45-year-old man who presented with abdominal pain, fever and weight loss. Ultrasound and computed tomography of the abdomen showed multiple cystic lesions in the liver. Ultrasound guided needle aspiration revealed yellowish brownish aspirate, which was flooded with acid-fast bacilli. The abscess was drained under ultrasound guidance. Subsequent abdominal ultrasound a few days later showed resolution of the abscess cavity. He was concomitantly started on systemic antituberculous therapy. A tuberculous liver abscess has to be thought of in the differential diagnosis of liver abscesses and to consider the role of percutaneous drainage along with systemic antituberculous chemotherapy as an alternative to surgery in the management. A greater awareness of this clinical entity is required for successful treatment.

ABSTRACT

OBJECTIVE: To report a life-threatening anaphylactoid reaction to oral pefloxacin in a patient with AIDS and to review the pertinent literature. CASE SUMMARY: A 32-year-old woman with AIDS developed an anaphylactoid reaction following a second exposure to oral pefloxacin. This reaction was characterized by severe hypotension, dizziness, itching, and fever. DISCUSSION: Fluoroquinolones are broad-spectrum antimicrobial agents. They are used frequently in patients with AIDS for numerous indications, including treatment of Mycobacterium avium complex. Pefloxacin, a broad-spectrum fluoroquinolone, was introduced in France in 1985. Since then, many patients with AIDS have been treated with this drug. Several cases of anaphylactoid reactions to ciprofloxacin have been documented in patients with HIV infection. To our knowledge, this is the first reported case of an anaphylactoid reaction to pefloxacin in a patient with AIDS. CONCLUSIONS: There is a need for continued vigilance in the reporting of adverse drug reactions in patients with AIDS, especially with new drug. Also, care must be taken in introducing drugs, including fluoroquinolones, to this patient population.

ABSTRACT

Brucellosis is one of the main zoonoses in the world. In Saudi Arabia, it was recognized as a major health problem in 1983G and since then many measures have been implemented to control the disease. We conducted a study to determine the yearly incidence and seasonal variation of blood culture positive brucellosis (Brucella cases) diagnosed at King Khalid University Hospital (KKUH) in Riyadh between 1985G and 1991G. The results showed that there was a fivefold decline in the incidence of Brucella cases over the seven years of the study from 8.6 cases/1000 admissions in 1985G to 1.4 cases/1000 admissions in 1991G. The disease showed a prevalence that extended throughout year with the majority of cases occurring during spring, summer and early fall. The possible reasons for the seasonal variation and decreasing incidence of brucellosis noted in this study are discussed.

ABSTRACT

The prevalence of pathogenic intestinal parasites among preschool children in Al-Medina district, Saudi Arabia, was determined through a randomized multistage sampling of 8000 preschool children. Duplicate specimens from each child were examined using a simple sedimentation technique. The overall prevalence of intestinal parasites among children screened was 18.4%. The most common parasite isolated was Giardia lamblia (14.5%). This was followed by Entamoeba histolytica (2.7%), Enterobius vermicularis (1.4%), Ascaris lumbricoides (1.0%) and others. Out of the 1462 children positive for parasites, 183 (12.5%) had mixed parasitic infections. Prevalence among preschool children was highly associateed with older age, rural residence, non-municipal water supply, inadequate latrine type, low level of parental education, abdominal pain, and diarrhea.
