Brief Answer: Subtype not going to affect the treatment pattern Detailed Answer: Hi, Welcome to XXXXXXX Thanks for sending your query. You need not bother about sub-types as it has nothing to do with the treatment pattern. Sub-type is useful only for epidemiological purpose to identify and trace the source. HIV is well manageable disease nowadays with the help of very good Antiretroviral drugs. One can live not less than thirty years after infection without much of problem. They can earn their livelihood and support their family. Meanwhile there is every chance for a total cure in the recent future by which one can wash out their infection totally. Approach a HIV care center and follow their guidance regularly. You will have decent and comfortable life. Dr S.Murugan

Brief Answer: Negative RNA PCR/CMIA confirms you are HIV free. Detailed Answer: Hi, Welcome back. Sorry if I had understood your question in wrong way and answered. A negative RNA PCR 1/2 and CMIA 7 months after the high risk activity is very much conclusive that your absolutely HIV free. No more test is necessary. When your test was negative why do we have to bother about the subtypes prevalent in Thailand? It is definite whatever may be your symptoms, they are not related to HIV. No second thought is necessary. Forget about that incident. Dr S.Murugan

Brief Answer: Symptoms not related to HIV as DUO test is negative Detailed Answer: Hi, Welcome once again. You had described all your past symptoms. As your DUO test was negative after 7 months and all your STD test came negative, These symptoms could not be due to HIV/STD. Earliest symptoms for HIV can occur only after 4 weeks of possible infection. Your symptoms started after two days. Swollen lymph nodes, dry cough, chest pain, ARS like symptoms ,oral ulcers and also boils over scalp for your partner can occur without the presence of HIV, in other ordinary infections. You need not worry about these. Just forget about the past incidence. Dr S.Murugan

hi only urethral burning started post 2 days all other symptoms started ard 3-4 eeeks later also girlfrnd had ulcers on labia (pink area) of vagina that lasted for a month despite antibiotics ...application of nadibact cream helped though ..experienced all symptoms in the book though ...including perephral neuropathy (tingling itching crawling on face while sleeping)what else could cause all of this kindly advice
doctor
Answered by Dr. Sankaranantham Murugan (2 hours later)
Brief Answer: Examination, further investigations to fix cause Detailed Answer: Hi, Welcome back. Urethral burning 2 days after sex needed evaluation of urine for STD causes. Ulcers on labia of your girl friend also have to be examined whether they are just scratch ulcers or due to any STDs. If necessary tests for STD s to be repeated as there might be a possibility window period for these tests. Throat infection, ordinary flu or a viral fever could have appeared as ARS. Once again assure you that you need not bother about HIV, otherwise repeat the test after 90 days to get a doubly sure negative HIV result along with antibody detection component of the DUO test also reliable at that time.

Brief Answer: No need to repeat test for STD,consult physician. Detailed Answer: Hi, Welcome once again. I can understand your concern. If the STD tests had been carried out 6 months after exposure no further STD tests are necessary. Regarding the ulcers over vulva of your girl friend I could extend more inputs only if had examined her lesions. Without that it would not possible to arrive at any diagnosis. Scaling of palms, seborrhea, pins and needles are not earlier symptoms in HIV. Those can occur after 5-7 years after infection when the immunity of the individual goes beyond the threshold stages. Contact dermatitis of palms had to be ruled out. Seborrhea can occur to anybody. Pins and needles indicates peripheral neuropathy. Alcoholism, diabetes have to be ruled out. Your physician can guide you better. Dr S.Murugan

all these things including diabetes have been ruled out ...also could such ulcers on the pink area be caused due to waxing
doctor
Answered by Dr. Sankaranantham Murugan (4 hours later)
Brief Answer: Walking will not cause genital ulcers in females. Detailed Answer: Hi, Do you mean walking or waxing? 1. Diabetes has to ruled out in patients who had pin and needles sensation and not for labial ulcer. 2. Vulval or labial ulcers cannot be caused by walking. I do not expect waxing to cause ulcers lasting for months. While sexual trauma can cause ulcers in genitals of both sex. But these can be easily differentiated by mere inspection only by an experienced genito-urinary, or a STD physician or a Dermato-venereologist. Dr S.Murugan

was talking about waxing the ulcers have healed completely now though they looked like ulcers caused by STDs but me nvr got genital ulcer and also she had a facial rash which was probably triggered as an allergy to over use of an acne cream....all in all can one simply rely on these tests at least as far as HIV is concerned irrwspective of subtypes or symptoms or other things ...also why such coincidental symptoms in terms of time also coincidental
doctor
Answered by Dr. Sankaranantham Murugan (6 hours later)
Brief Answer: Waxing can cause ulceration at the sites. Detailed Answer: Hi XXXX, Welcome back. Waxing can cause ulcers like this and they can heal spontaneously by natural healing power of the body or with some antibiotic creams like Nadibact. Our body is susceptible for so many changes due to natural process and also due to the environmental conditions. So, also acne, seborrheic, flu, throat infection, rashes allergic reactions can occur to anybody and it can coincide with our other activities including sex. So ignore those minor ailments. You need not worry as you are HIV/STD free.

COBAS® AmpliPrep/COBAS® TaqMan® HIV-1 Test and CMIA 4TH GENRRATION DUO TEST AG/AB are the tests conducted could u please confirm their conclusivity as far as my case is concerned...at 6 mths over....one has done tridot also but apparently tridot (j.mitra) dsnt detect subtype E ....read it on their page ....thank u for ur tremendous support
doctor
Answered by Dr. Sankaranantham Murugan (6 hours later)
Brief Answer: CMIA 4th generation test is superior to Tridottest Detailed Answer: Hi, Welcome again and again. Tridot is definitely inferior to the CMIA 4th generation test and CMIA 4th generation test detects both P24 antigen and antibodies against HIV. As you had this test 6 months after the high risk activity and the negative test had ruled out both Antigen and Antibodies against HIV, there is no chance of HIV for you anymore. Just forget the same and continue your activities as usual. Regarding COBASA Ampliprep/Cobasa is also from a highly reputable company and highly reliable one, but it measures mainly HIV RNA and it is useful only to already infected people to assess the prognosis of the disease (severity and response to treatment). That in not an opt test for you whereas a negative CMIA 4th generation test is more than sufficient and it is confirmed that you are HIV free and no more further test is necessary. Dr S.Murugan

Brief Answer: DNA PCR is more useful in diagnosis of HIV. Detailed Answer: Hi, Welcome back. Some experts are using HIV RNA PCR to confirm or rule out HIV. In my opinion DNA PCR is more useful for diagnostic purpose and RNA PCR for prognostic purpose. Regarding the detection of sero-typing of HIV and usefulness of COBAS AMPLIPREP, I don't have any clinical experience and with my patients. Sorry I am not in a position to say more about this sero-typing. Dr S.Murugan

Brief Answer: CD4 count is within normal limits. Detailed Answer: Hi XXXX, Glad to hear from you. Your CD4 count is quite normal. Anything ranging in between 500-1200 cells/cu.mm is quite within normal limits. During a spell of an viral episode or some other infection it may likely to fall. Once the body recovers from the infection, and not due to the medicine you took, CD4 count will recover to normal level. This is normal for anybody and not related to HIV anyway. So once again relax and nothing to worry. Dr S.Murugan

hi urethral swab done 6 weeks post exposr had come pos for gram positv diplococci, gram negatv bacilli and throat swab came pos for streptococcus does it explain anything
doctor
Answered by Dr. Sankaranantham Murugan (15 hours later)
Brief Answer: If no symptom, just ignore the same. Detailed Answer: Hi XXXX, Pleased to answer your question. Presence of Gram Negative diplococcic (gono cocci) indicates the presence of STD infection as a cause for urethritis. Your results of urethral swab did not reveal any Gram negative diplococci. Gram positive diplococci and Gram negative bacilli may be a component of normal urethral flora and likely to be non-pathogenic. You need not worry about the same. If you have any complaints related to urinary tract like burning sensation or fever then it has to be treated. Otherwise it can be ignored. Dr S.Murugan

doctor
Answered by Dr. Sankaranantham Murugan (34 minutes later)
Brief Answer: Streptococcus sore throat common and easy to treat Detailed Answer: Hi XXXX, Throat infection is such a common condition throughout the world, especially in India. Stretococcus is a common pathogen in throat. It can be easily treated with appropriate antibiotics. Any physician, especially an ENT surgeon will be able to treat the condition without much difficulty. If necessary a culture and sensitive test has to be carried out and the outcome of the result will guide the physician for the appropriate management. It has unlikely to have any relation to HIV as you are free from HIV. Dr S.Murugan
