    J Dermatol, 2000 Apr;27(4):225-32.
    PMID: 10824485
    A retrospective analysis of 182 HIV positive Malaysians was done in two centers, the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic and clinical data were analyzed. The analysis showed that 130 out of 182 patients had mucocutaneous disorders (71.4%). In the study there were 125 males (96.2%) and 5 females (3.8%). The majority of the patients were in the age group from 20 to 50 years. The patients who presented with mucocutaneous disease also had low CD4+ T lymphocyte counts, and most of them had AIDS defining illnesses. The number of cases with generalized hyperpigmentation was very high (35.7%), followed by papular eruptions (29.1%) and xerosis (27.5%). Seborrheic dermatitis was seen in 19.2% of the cases and psoriasis in 7.7%. The most common infections were oral candida 35.7%, tinea corporis and onychomycosis 9.9%, and herpes infection 4.3%. However, mucocutaneous manifestations of Kaposi's sarcoma were rare. The results suggested that mucocutaneous findings are useful clinical predictors of HIV infection or a sign of the presence of advanced HIV infection.

    Southeast Asian J. Trop. Med. Public Health, 2000 Jun;31(2):283-6.
    PMID: 11127327
    The HIV-1 genetic variation in 60 infected Malaysian intravenous drug users (IDU) was studied by comparison of the nucleotide sequences and their predicted amino acid sequences in the V3 loop of the external glycoprotein gp120. In this study, HIV-1 B, C and E subtypes were identified among Malaysian IDU, with HIV-1 B being the predominant subtype (91.7%). HIV-1 C and HIV-1 E were minority subtypes among Malaysian IDU. Analysis of the amino acid alignment of the C2-V3 region of the env gene suggests a genetic relationship between Thai and Malaysian B and E subtype strains. This study serves as a baseline for monitoring HIV-1 genetic diversity and spread in Malaysia.

  4. Fine needle aspiration cytology of lymph nodes in HIV-infected individuals
    Jayaram G, Chew MT
    Acta Cytol., 2000 Nov-Dec;44(6):960-6.
    PMID: 11127753
    OBJECTIVE: To assess the role of fine needle aspiration cytology (FNAC) in lymphadenopathy in human immunodeficiency virus-infected individuals (HIVII).

    STUDY DESIGN: Thirty-nine HIVII presenting with lymphadenopathy at University Hospital, Kuala Lumpur, were subjected to FNAC. Cytologic smears were routinely stained with May-Grünwald-Giemsa stain. Special stains and immunostains were used when necessary.

    RESULTS: In nine cases, the cytologic appearance was compatible with HIV type A and in one case with HIV type C lymphadenopathy. In 21 cases, acid-fast bacilli (AFB) were demonstrated in the cytologic smears, enabling a diagnosis of mycobacterial lymphadenitis. In one of these cases there was a concomitant infection with Penicillium marneffei that was overlooked on initial cytologic examination. The cause of granulomatous lymphadenitis could not be ascertained in one case, where neither AFB nor any other organisms were demonstrable. Two cases of histoplasma and one of cryptococcal lymphadenitis were diagnosed, as was one high grade non-Hodgkin's lymphoma that could be immunophenotyped on cytologic material. In three cases the aspirates were inadequate for a cytologic diagnosis.

    CONCLUSION: Lymph node FNAC is a valuable investigative modality in HIVII. Most opportunistic infections (bacterial and fungal) can be correctly identified, and high grade lymphoma can be diagnosed and phenotyped.

    PMID: 12118468
    The human immunodeficiency virus (HIV) epidemic has had a profound influence on the epidemiology of tuberculosis (TB). The potential for HIV-associated TB cases to transmit M. tuberculosis and to produce a secondary increase in TB morbidity is unknown. A cross-sectional study was carried out to compare the prevalence of M. tuberculosis infection among the household contacts of HIV-positive and HIV-negative pulmonary tuberculosis (PTB) patients. Records of tuberculin (Mantoux) tests administered during routine contact investigations at the Chest Clinic, Hospital Kota Bharu, from 1999 to 2000 were reviewed. The HIV status of the patients was based on the results of ELISA tests while information on household contacts was gathered during visits to their houses. Ninety-four contacts of 39 HIV-negative patients and 44 contacts of 17 cases of HIV-positive patients were included in this preliminary study. 30% (12/40) of the contacts of HIV-positive PTB had a positive tuberculin compared with 52.8% (47/ 94) of the contacts of HIV-negative patients [OR = 0.41, 95% Confidence interval (CI) 0.17 - 0.97; p = 0.016]. The difference was still significant after performing multivariate logistic regression analysis to adjust for variables associated with infectiousness of TB (adjusted OR = 0.24, 95% CI 0.07 - 0.87; p = 0.03). This study has shown that HIV-infected PTB patients are less infectious to their contacts than HIV-negative patients. The presence of MV in the community may not necessitate a change of the current policy of the management of contacts.

  6. Fulltext Seroepidemiology of toxoplasmosis among HIV-infected patients and healthy blood donors
    Nissapatorn V, Kamarulzaman A, Init I, Tan LH, Rohela M, Norliza A, et al.
    Med J Malaysia, 2002 Sep;57(3):304-10.
    PMID: 12440270 MyJurnal
    A cross-sectional study was carried out in University of Malaya Medical Centre, Kuala Lumpur. Blood samples from 100 HIV-infected patients and 203 Healthy Blood Donors (HBD) were collected and anti-Toxoplasma antibodies were detected by using conventional ELISA. The seroprevalence of toxoplasmosis in HIV/AIDS and Healthy Blood Donors were found to be 21% and 28.1% respectively. There was no significant association between the seroprevalence of toxoplasmosis and various possible risk factors i.e. contact with cat, consumption of undercooked meat and history of blood transfusion in both groups. No significant differences between Toxoplasma seroprevalence in HIV/AIDS and Healthy Blood Donors in association with presence of single or multiple risk factors were found. The mean CD4 count among HIV/AIDS patients in this study was 202.23 cell/cumm. There was no significant association between CD4 count and seropositivity for Toxoplasma antibodies in HIV/AIDS patients.

  7. Fulltext AIDS-related opportunistic infections in Hospital Kuala Lumpur
    Nissapatorn V, Lee C, Quek KF, Abdullah KA
    Jpn J Infect Dis, 2003 Oct-Dec;56(5-6):187-92.
    PMID: 14695428
    We retrospectively reviewed 419 HIV/AIDS patients in Hospital Kuala Lumpur from 1994 to 2001. In the male group, the age range was 20-74, with a mean age 37 years, while in the female group it was 17-63, with a mean age of 33 years. With regard to age group, it was found that the preponderant age group was 25-34 years. The majority of male subjects were Chinese (52.5%), single (56.3%), and unemployed (55.1%), whereas the females were Malay (42.3%), married (79.5%), and non-laborer (64.1%). Also, both groups resided in Kuala Lumpur and had heterosexual contact as the leading cause of HIV transmission. More than half of the patients had CD4 cell counts of <200 cells/cumm. We found that the acquisition of HIV infection via intravenous drug use (IDU) was directly related to the incidence of tuberculosis infection (P < 0.05). Further analysis showed HIV-related tuberculosis with IDU was also dependently correlated with occupational status (unemployed) (P < 0.05). The four main AIDS-defining diseases include tuberculosis (48%), Pneumocystis carinii pneumonia (13%), toxoplasmic encephalitis (11%), and cryptococcal meningitis (7%); in addition, 53% of these patients were found to have CD4 cell counts of less than 200 cells/cumm at the time of diagnosis.

  8. Toxoplasmosis in HIV/AIDS patients: a current situation
    Nissapatorn V, Lee C, Quek KF, Leong CL, Mahmud R, Abdullah KA

    PMID: 15329448
    The seroprevalence of toxoplasmosis among 505 of human immunodeficiency virus (HIV)/AIDS patients was 226 (44.8%; 95% CI 42.64-51.76): 27 (47.4%) and 199 (44.4%) showed Toxoplasma seropositivity with and without toxoplasmic encephalitis (TE), respectively (P <0.05). The majority of these patients were in the 25-34 age group (44 versus 39%), male (86 versus 76%), and Chinese (49 versus 53%), though no statistical significance was found between the two. Significant differences between these two groups were noted, however, in terms of marital status, occupation, and present address. The heterosexual exhibited the most frequent behavior at risk for HIV infection, and accounted for 51 and 59% of patients with and without TE, respectively. Only 17/260 (6.5%) and 1/137 (0.7%) of them later acquired TE after receiving primary chemoprophylaxis (cotrimoxazole) and antiretroviral therapy including HAART (P <0.05). Fifty-seven (11.3%) out of those 505 patients were diagnosed with AIDS-related TE. The most common clinical manifestation was headache (56%). The computed tomography scan findings showed most lesions to be multiple (96.4%), hypodense (66.7%), and in the parietal region (39.3%). Twenty-seven (47.4%) patients had chronic (latent) Toxoplasma infection as evidenced by seropositivity for anti-Toxoplasma (IgG) antibody. At the time of diagnosis, the range of CD4 cell count was from 0-239 with a median of 25 cells/cumm. We also found that a CD4 count of less than 100 cells/cumm was significantly associated with development of TE (P <0.05). Clinical outcomes showed that among those who survived, 21 (36.8%), 16 (28.1%), and 2 (3.5%) of patients had completed treatment, transferred out, and were lost to follow up, respectively. Unfortunately, 18 (31.6%) of the cases were officially pronounced dead. Overall, 7 (12.3%) patients were detected as recurrent TE in this study.

  10. Global overview of injecting drug use and HIV infection among injecting drug users
    Aceijas C, Stimson GV, Hickman M, Rhodes T, United Nations Reference Group on HIV/AIDS Prevention and Care among IDU in Developing and Transitional Countries
    AIDS, 2004 Nov 19;18(17):2295-303.
    PMID: 15577542
    OBJECTIVE: To provide global estimates of the prevalence of injecting drug use (IDU) and HIV prevalence among IDU, in particular to provide estimates for developing and transitional countries.

    METHODS: Collation and review of existing estimates of IDU prevalence and HIV prevalence from published and unpublished documents for the period 1998-2003. The strength of evidence for the information was assessed based on the source and type of study.

    RESULTS: Estimates of IDU prevalence were available for 130 countries. The number of IDU worldwide was estimated as approximately 13.2 million. Over ten million (78%) live in developing and transitional countries (Eastern Europe and Central Asia, 3.1 million; South and South-east Asia, 3.3 million; East-Asia and Pacific, 2.3 million). Estimates of HIV prevalence were available for 78 countries. HIV prevalence among IDU of over 20% was reported for at least one site in 25 countries and territories: Belarus, Estonia, Kazakhstan, Russia, Ukraine, Italy, Netherlands, Portugal, Serbia and Montenegro, Spain, Libya, India, Indonesia, Malaysia, Myanmar, Nepal, Thailand, Viet Nam, China, Argentina, Brazil, Uruguay, Puerto Rico, USA and Canada.

    CONCLUSIONS: These findings update previous assessments of the number of countries with IDU and HIV-infected IDU, and the previous quantitative global estimates of the prevalence of IDU. However, gaps remain in the information and the strength of the evidence often was weak.

  11. Treatment of chronic hepatitis B in HIV co-infected patients
    Guan R
    Med J Malaysia, 2005 Jul;60 Suppl B:52-6.
    PMID: 16108174
    In the Asia Pacific region Human Immunodeficiency virus (HIV) is often acquired in individuals already infected with hepatitis B virus (HBV). The immune suppression caused by HIV infection reduces cellular immune response against HBV and liver inflammation may improve, but the risk of developing cirrhosis is not. HBV infection does not affect the progression of HIV disease. Anti-retroviral agents may be directly hepatotoxic and cause ALT elevations in patients with chronic hepatitis. Highly active anti-retroviral therapy (HAART) improves immunity and as cytotoxic lymphocyte responses improve, hepatitis flares can occur, usually r within 3 months of initiation of HAART. These hepatitis flares may be followed by normalization of ALT and clearance of HBVDNA. If lamivudine is included in the HAART regime, hepatitis flares may not occur till late and these late flares signal the development of lamivudine resistant HBV strains (90% of HBV/HIV co-infection). Treatment options for chronic HBV infection include interferon (IFN), and nucleoside analogues. Lamivudine, adefovir dipivoxil, tenofovir disoproxil fumarate (DF) are nucleoside analogues with activity against both HBVDNA polymerase and HIV reverse transcriptase. The latter two compounds have added activity against lamivudine resistant HBVDNA. Lamivudine should be avoided in the initial treatment of both hepatitis B as well as HIV because of the high incidence of resistance. Interferon should be considered first for treatment of HBV in HIV co-infected individuals and is usually unsuccessful in the later stages of HIV infection when immune suppression is extreme. As new and improved agents in HAART continue to prolong survival, the use of liver transplantation for cirrhotic patients co-infected with HIV and HBV may increase.

    Southeast Asian J. Trop. Med. Public Health, 2005;36 Suppl 4:30-3.
    PMID: 16438176
    A total of 66 fecal specimens obtained from patients infected with human immunodeficiency virus (HIV) from Kajang Hospital were screened for Cryptosporidium oocysts. The fecal specimens were concentrated using the formalin ethyl acetate concentration technique, stained with modified Ziehl-Neelsen and confirmed with immunofluorescence stain. It was established that 2 (3.0%) were positive for Cryptosporidium. The two cases involved a Chinese local man (with diarrhea) and an Indonesian foreigner (without diarrhea). A higher index of suspicion for clinical cryptosporidiosis in HIV patients, including those with chronic weight loss with or without diarrhea, is recommended. In addition, laboratory testing for Cryptosporidium in HIV-infected patients is highly recommended in order to have a better understanding of the epidemiology and management of the disease in Malaysia.

    Human Immunodeficiency Virus (HIV)-related pulmonary hypertension is a relatively rare disease that can affect HIV sufferers. This is almost always associated with a poor outcome and death. An 18 month-old girl, probably the youngest on record, was diagnosed to have pulmonary hypertension (PHT) and retrospectively found to have HIV infection. Sildenafil was used to control her PHT and she remains alive even after 2 years.

    PMID: 17896968
    Attempts to address the significant impact of HAART on medical variables on the Malaysian HIV/AIDS population have yet to be evaluated. This study aims to analyze the proportions of AIDS-defining illnesses (ADIs) before and after HAART. A retrospective study was carried out on 128 new cases of HIV infected patients who first commenced HAART in 2004 at the national HIV reference center. Before commencement of HAART, 76 clinical episodes of ADIs were recorded in 52 patients. Most common being pulmonary Mycobacterium tuberculosis (28.9%), PCP (27.6%) and disseminated and extrapulmonary Mycobacterium tuberculosis (11.8%). During HAART, 8 clinical episodes of ADIs were documented in 7 patients with a median time of onset of 10 weeks after initiation of HAART (range, 4-36 weeks). The median CD4 count at the time of the commencement of HAART for these patients was 11 cells/mm(3). ADIs reported include PCP (2 episodes), disseminated and extrapulmonary Mycobacterium tuberculosis (2 episodes), extrapulmonary cryptococcosis (1 episode), esophageal candidiasis (1 episode), recurrent pneumonia (1 episode) and disseminated or extrapulmonary histoplasmosis (1 episode). Three (37.5%) of these occurred despite a reduction of viral load by at least 2 log(10) and an increased in the CD4 cell count. In conclusion, ADIs can still present after the initiation of successful HAART especially in those with CD4 counts below 100 cells/mm(3). In Malaysia, ADIs are the major causes of HIV/AIDS associated morbidity and mortality, thus increased awareness on the management of these illnesses is warranted especially in the months following HAART.

    PMID: 18830542
    Tuberculosis (TB) affects one-third of the world's population. Anti-TB drugs with isoniazid, rifampicin and pyrazinamide are very effective but they can cause hepatotoxicity. Many risk factors have been recognised. Data on prevalence of anti-TB drug-induced hepatitis as well as the contributing risk factors are scarce in Malaysia. This observational case control study was designed to look at the prevalence and the risk factors of drug-induced hepatitis in our population.

  16. Detection of IgM and IgG antibodies to Cryptococcus neoformans proteins in blood donors and HIV patients with active cryptococcosis
    Chai HC, Tay ST
    Mycoses, 2009 Mar;52(2):166-70.
    PMID: 18643920 DOI: 10.1111/j.1439-0507.2008.01549.x
    The serological responses to Cryptococcus neoformans proteins of blood donors and HIV patients with active cryptococcosis from a tropical region were investigated in this study. Exposure to C. neoformans, an organism ubiquitous in the environment, contributes to the antibody responses observed in the blood donors. IgG responses to cryptococcal proteins were stronger than IgM responses in most sera tested in this study. A 53-kDa cryptococcal protein fragment was identified as the most immunoreactive protein on the IgM immunoblots of both blood donors and patients. Overall, there was no obvious difference in IgG responses of patients when compared with blood donors. Some immunogenic protein fragments (27.5, 76, 78 and 91.5 kDa) were detected at least two times more frequently on IgM immunoblots of patients compared with those of blood donors. It is yet to be investigated whether the proteins identified in this study may have any potential to be used as biomarker for cryptococcosis.

    This represents the first study to determine the genetic diversity of Blastocystis sp. among cancer and HIV/AIDS patients. Forty Blastocystis sp. isolates obtained from 20 cancer and 20 HIV/AIDS patients were genotyped by PCR using seven pairs of known sequenced-tagged site primers. Out of the 40 isolates, 38 were identified as one of the known genotypes and two isolates were negative with all the STS primers. Blastocystis sp. subtype 3 which is reported to be associated with disease was found to be predominant among the study subjects.

    Although drugs are haram and therefore prohibited in Islam, illicit drug use is widespread in many Islamic countries throughout the world. In the last several years increased prevalence of this problem has been observed in many of these countries which has in turn led to increasing injecting drug use driven HIV/AIDS epidemic across the Islamic world. Whilst some countries have recently responded to the threat through the implementation of harm reduction programmes, many others have been slow to respond. In Islam, The Quran and the Prophetic traditions or the Sunnah are the central sources of references for the laws and principles that guide the Muslims' way of life and by which policies and guidelines for responses including that of contemporary social and health problems can be derived. The preservation and protection of the dignity of man, and steering mankind away from harm and destruction are central to the teachings of Islam. When viewed through the Islamic principles of the preservation and protection of the faith, life, intellect, progeny and wealth, harm reduction programmes are permissible and in fact provide a practical solution to a problem that could result in far greater damage to the society at large if left unaddressed.

    PMID: 19627508 DOI: 10.1111/j.1439-0507.2009.01750.x
    This study describes the isolation of Cryptococcus neoformans and Cryptococcus gattii from patients with chronic meningitis who were admitted to 16 Malaysian hospitals, from 2003 to 2004. Of the 96 cryptococcal cases reported over the 2-year period, 74 (77.1%) patients were male and 45 (46.9%) patients were between 30 and 39 years old. Cryptococcosis was uncommon in children. A total of 57 (59.4%) and 23 (24.0%) patients were Malay and Chinese respectively. Human immunodeficiency virus infection was the major underlying disease reported in 36 (37.5%) patients. C. neoformans var. grubii (serotype A and molecular type VNI) was the predominant Cryptococcus species isolated from 88.5% of cryptococcal cases in this country. Cryptococcal cases due to C. neoformans var. grubii were reported from all the five regions in Malaysia, with the most number of cases reported from the central and northern regions. Cryptococcus gattii (all were serotype B and molecular types VGI/II) was isolated from all regions except the southern region. Compared with a study conducted prior to the AIDS era, our findings show substantial changes in the demographical characteristics of patients.
