HIV (human immunodeficiency virus) infection is prevalent in many areas of sub-Saharan Africa. Seropositivity rates reach 10-15% in urban adults, 21% in critically ill adults and 30% in surgical inpatients aged 21-40 years. AIDS (acquired immune deficiency syndrome) is a multisystem disease which presents to the surgeon with a wide range of pathologies including Kaposi's sarcoma, lymphadenopathy and sepsis. The more common sites for sepsis are the female genital tract, anorectum, pleural cavity, soft tissues (necrotizing fasciitis) and bone and joints. To prevent iatrogenic HIV infection more use should be made of autologous blood. Occupational exposure to HIV infection can be minimized by double-gloving, protecting the eyes when operating and ensuring that theatre gowns are waterproof. The risk of HIV infection from a needlestick injury is 0.4%. Although contact with blood during a surgical procedure is common, the risk is lower than for a hollow needlestick injury. PIP: In Zambia, 10-15% of urban adults are reported HIV positive, as are over 80% of prostitutes. The HIV seroprevalence rate in a Lusaka hospital's intensive care unit was 21% (27% for surgical and 18% for trauma admissions). HIV-infected patients could be clinically recognized by risk factors or symptoms and signs: weight loss, chronic cough, chronic diarrhea, sepsis, septic arthritis, subacute hematogenous osteomyelitis, a history of sexually transmitted diseases (STDs), death of a spouse or of a child under age 2, recent pregnancy unable to go to term, poor quality or thin hair, appearance of aging beyond years, mental slowness, persistent or unexplained fever, lymphadenopathy, aggressive atypical Kaposi's sarcoma, oral thrush, hairy leukoplakia of the tongue, shingles scars, and scars of maculopapular dermatitis. Common sites for HIV-related sepsis are the female genital tract, anorectum, pleural cavity, soft tissues (e.g., necrotizing fascitis), and bone and joints. Autologous blood transfusion and use of donor blood screened for HIV antibodies, preferably limited to emergencies, would reduce the likelihood of iatrogenic HIV transmission. Surgeons should wear two pairs of gloves, a waterproof gown, and goggles to protect themselves from HIV transmission. If they have skin rashes, cuts, or abrasions on the hands or arms, they should not perform operations. Proper cleaning and disinfection of endoscopes are required. The risk of infection from a needle stick is small ( 0.4%).

The prevalence of parasitic infections was investigated in human immunodeficiency virus (HIV)-infected patients (n = 105) who visited Seoul National University Hospital, Seoul, Korea, during the period from 1995 to 2003. Fecal samples were collected from 67 patients for intestinal parasite examinations, and sputum or bronchoalveolar lavage samples from 60 patients for examination of Pneumocystis carinii. Both samples were obtained from 22 patients. Thirty-three (31.4%) of the 105 were found to have parasitic infections; Cryptosporidium parvum (10.5%; 7/67), Isospora belli (7.5%; 5/67), Clonorchis sinensis (3.0%; 2/67), Giardia lamblia (1.5%; 1/67), Gymnophalloides seoi (1.5%; 1/67), and Pneumocystis carinii (28.3%; 17/60). The hospital records of the 11 intestinal parasite-infected patients showed that all suffered from diarrhea. This study shows that parasitic infections are important clinical complications in HIV-infected patients in the Republic of Korea.

The incidence of specific intracranial parenchymal lesions of HIV-infected patients varies considerably between countries. In the Republic of Korea, the number of HIV-infected patients is increasing, but little is known regarding the spectrum of intracranial parenchymal lesions in these patients. The aim of the present study was to obtain this information. To identify HIV patients with intracranial parenchymal lesions, the electronic database of radiological reports for 1,167 HIV-infected patients, seen from 1999 to 2008 at the Seoul National University Hospital, were reviewed. Neuroradiologic studies were performed on 165 of these patients, and intracranial parenchymal lesions were detected in 40 (3.4%) of them. Thirty-seven were male, and median age was 41 yr (range, 26-61). At the time of the diagnosis of intracranial parenchymal lesions, median CD4+ lymphocyte count was 40 cells/microL (range 5-560) and in 33 (82.5%) patients, it was less than 200 cells/microL. Progressive multifocal leukoencephalopathy (12 patients) is the most frequent intracranial parenchymal lesions, followed by intracranial tuberculoma (7 patients), primary central nervous system lymphoma (7 patients), intracranial cryptococcoma (4 patients), Toxoplasma encephalitis (4 patients), and disseminated non-tuberculous mycobacterial infection (3 patients).

OBJECTIVETo assess the incidence of oral candidiasis and its influencing factors in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).

METHODSAn oral examination was conducted in the 1 566 HIV/AIDS patients in the Third Hospital of Kunming from March 2008 to September 2012 (M/F: 1 062/504, age range: 0.2 to 84.0 years old). The HIV viral load (HIV- RNA) and peripheral blood CD4 count were respectively analyzed by Bayer Q340 fluorescence signal surveying instrument (bDNA method) and flow cytometry analysis. The information on usage of highly active anti-retroviral (HAART) drugs and transmission of HIV were obtained through questionnaires. The incidence of oral candidiasis in patients with different HIV-RNA levels and CD4 count and the use of HAART was analyzed and compared.

RESULTSThe total incidence of oral candidosis was 31.0% (486/1 566) and there was no difference in sex. The oral lesions were presented by three types, psudomembranous candidosis (PC), erythematous candidosis (EC) and angular cheilitis (AC), and the morbidity was 13.9% (217/1 566), 17.0% (267/1 566) and 4.9% (77/1 566), respectively. The average level of CD4 count in psudomembranous candidosis, erythematous candidosis and angular cheilitis [81.0 (146.0), 74.0 (152.0) and 69.0 (121.5) cell/µl] showed no significant difference (P > 0.05). The incidence of oral candidiasis in non-HAART and HAART subjects were 36.3% (402/1 107) and 18.3% (84/459), respectively (P = 0.000). The CD4 count and absolute counts of HIV viral load in oral candidiasis patients and non-oral candidiasis patients had significant difference (Z = -10.261, P = 0.000 and Z = -4.762, P = 0.000).

CONCLUSIONSThe morbidity of oral candidiasis in HIV/AIDS patients in Yunnan Province was high, including PC, EC and AC and hyperplastic candidosis was not detected. The incidence was related to the degree of immune suppression and HIV viral load.

OBJECTIVETo analyze Helicobacter pylori infection in the gastric mucosa of patients with HIV/AIDS in different clinical stages.

METHODSThis study involved 170 patients with HIV/AIDS and 34 HIV-negative patients. All the patients underwent upper endoscopy and antral gastric biopsy to determine the status of Helicobacter pylori infection using aniline red staining and rapid urease test. The patients with HIV/AIDS were stratified based on CD4(+)T lymphocyte counts and clinical setting into asymptomatic HIV infection (A1, A2) group, symptomatic HIV infection (B1, B2) group and AIDS (A3, B3, C1-3) group.

RESULTSThe prevalence of Helicobacter pylori infection in HIV/AIDS patients was 16.5% (28/170), and in the 3 groups classified, the infection rates were 23.4% (11/47), 14.0% (8/57), and 13.6% (9/66), respectively; the infection rate was 47.1% (16/34) in the control group. Helicobacter pylori infection rate in the gastric mucosa of the patients with HIV/AIDS in different clinical stages was significantly lower than that of the control group (P<0.05); the infection rates in symptomatic HIV-infected (B1, B2) group and AIDS (A3, B3, C1-3) group were significantly lower than that in asymptomatic HIV-infected (A1, A2) group (P<0.05).

CONCLUSIONThe low Helicobacter pylori infection rate in HIV/AIDS patients may result from severe immunodeficiency in the gastric mucosa.

A retrospective analysis was performed in two major HIV/AIDS referral hospitals in Beijing to evaluate the prevalence of Mycobacterium tuberculosis (MTB) and non-tuberculous mycobacterial (NTM) infections in HIV-infected patients. A total of 627 patients' data were reviewed, and 102 (16.3%) patients were diagnosed with culture-confirmed mycobacterial infection, including 84 with MTB, 16 with NTM, and 2 with both MTB and NTM. The most frequent clinical complication by mycobacterial infection was pulmonary infection (48/102, 47.1%). The overall rates of multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) were 11.9% and 3.4%, respectively. This study underlines the urgent need to intensify screening for mycobacteria coinfection with HIV and to prevent the spread of drug-resistant TB among HIV-infected patients.

The clinical features of HIV/AIDS-related ocular manifestations in Korean patients were investigated in this study. Data on 200 consecutive Korean patients diagnosed with AIDS who visited the Seoul National University Hospital from January 2003 to June 2008 were reviewed. Fifty-seven patients (28.5%) had ocular manifestations, and they showed significantly lower CD4+ T cell count than patients without ocular manifestations. Among them, 23 (40.3%) patients showed retinal microvasculopathy, and 22 (38.5%) patients showed cytomegalovirus (CMV) retinitis. Other manifestations included retinal vein occlusion (n = 4), herpes zoster ophthalmicus (n = 4), syphilitic uveitis (n = 2), acute retinal necrosis (n = 1), and progressive outer retinal necrosis (n = 1). The mean CD4+ lymphocyte counts of the patients with retinal microvasculopathy and cytomegalovirus retinitis were 108.5 cells/microL and 69.4 cells/microL, respectively. In conclusion, ocular manifestations including CMV retinitis are common complications in Korean patients with AIDS even in the era of highly active anti-retroviral therapy. Compared to previous reports in western countries, prevalence of CMV retinitis is relatively low and CD4+ lymphocytes count at the time of diagnosis is relatively high.

INTRODUCTIONHighly active antiretroviral therapy (HAART) has greatly changed the epidemiology of human immunodefi ciency virus (HIV) mortality. The aim of this study is to compare the causes of death and factors associated with early death in HIV-infected persons in the pre- and peri-highly active antiretroviral therapy (HAART) periods.

MATERIALS AND METHODSWe conducted a retrospective review of 483 HIV-infected persons who were diagnosed with HIV from 1985 to 2000, and had died within 5 years of the diagnosis. We examined the temporal change in the primary causes of death between those who were diagnosed in the pre-HAART (1985 to 1995) and peri-HAART (1996 to 2000) periods, and compared the demographic and clinical characteristics of the 2 groups.

RESULTSDuring the peri-HAART period, HIV encephalopathy, cryptococcal meningitis, and lymphoma were no longer the leading causes of death. Opportunistic infections remained important causes of death. Early deaths from the peri-HAART period were older (60 years and above) at diagnosis (Adj OR 7.50; 95% CI, 1.78 to 31.58), more likely to be divorced (Adj OR 5.05, 95% CI, 1.96 to 13.02) and tended to have a low baseline CD4 cell count of <50 cells/ uL (Adj OR 2.18, 95% CI, 1.14 to 4.16) , and were more likely to have received HAART (Adj OR 5.19; 95% CI, 2.22 to 12.12) than early deaths from the pre-HAART period.

CONCLUSIONIn the peri-HAART era, HIV-infected persons who died within 5 years of diagnosis were those who were older (≥60 years), divorced, or who presented with very late-stage disease (CD4 <50) at diagnosis. More targeted public health interventions, such as targeted public health messages and outreach to increase access to HIV testing and treatment should be developed for these subpopulations.
